as another implementation of the gully 5, as shown in fig. 2B, it may include: the rainwater collecting device comprises a second cavity 512, a first water collecting hanging basket 511, a second intercepting pipe 513 and a second on-off switch, wherein a second opening is formed in the top of the second cavity 512, rainwater and/or sewage are received through the first water collecting hanging basket 511 arranged on the second opening of the second cavity 512, when the rainwater and/or sewage in the second cavity 512 need to be intercepted, the rainwater and/or sewage received by the second opening are intercepted through the second intercepting pipe 513 arranged in the second cavity 512 and the second on-off switch, when the rainwater and/or sewage entering the second cavity 512 do not need to be intercepted, the second on-off switch is closed, so that the sewage and/or rainwater flows into a filtering device 6 from a first water outlet channel of the second cavity, and the sewage and/or rainwater received by the first water outlet channel are filtered through the filtering device 6; for example: in the early stage of rainfall, after the initial rainwater on the ground enters the second cavity 512, the second on-off switch is turned on, so that the initial rainwater is intercepted and discharged to the second downstream pipeline 7 through the second intercepting pipe 513; after the middle and later period rainwater in the middle and later periods of rainfall flows into the second cavity 512, the second on-off switch is closed, so that the middle and later period rainwater flows into the filtering device 6 through the first water outlet channel, is filtered by the filtering device 6 and then is discharged into the second downstream pipeline 7; therefore, the initial rainwater at the early stage of rainfall and the middle and later stage rainwater at the middle and later stages of rainfall are shunted through the first downstream pipeline 8 and the second downstream pipeline 7, and the technical means of shunting and intercepting sewage achieves the technical effect of shunting and discharging the initial rainwater and/or sewage (which can be understood as dirty water) with serious pollution and the clearer middle and later stage rainwater (which can be understood as clean water).

As for the gully 5, as another implementation manner of the gully 5, as shown in fig. 2C, it may further include: the third cavity 522, the second catchment cradle 521, the third cutoff pipe 523 and the third disconnecting switch 525 collect rainwater and/or sewage through the second catchment cradle 521 arranged on a third opening on the third cavity 522, when the rainwater and/or the sewage in the third cavity need to be cut off, the third cutoff pipe 523 and the third disconnecting switch 525 arranged in the third cavity 522 cut off the rainwater and/or the sewage received by the second catchment cradle 521, and when the rainwater and/or the sewage entering the third cavity do not need to be cut off, the third disconnecting switch is closed, so that the sewage and/or the rainwater flows into the filtering device 6 from a fourth water outlet of the third cavity, and the sewage and/or the rainwater received by the fourth water outlet is filtered by the filtering device 6; for example: after the mixed water of the initial rainwater and the sewage enters the third cavity 522 from the third water outlet 524 of the second catchment hanging basket 521 at the initial stage of rainfall, the on-off switch is turned on, so that the initial rainwater is intercepted and discharged to the first downstream pipeline 8 through the third intercepting pipe 523; after the rainwater in the middle and later periods of rainfall flows into the third cavity 522, the on-off switch is turned off, so that the rainwater in the middle and later periods flows into the filtering device 6 through the third water outlet 524, is filtered by the filtering device 6 and then is discharged into the second downstream pipeline 7; therefore, the initial rainwater at the early stage of rainfall and the rainwater at the middle and later stages are shunted through the first downstream pipeline 8 and the second downstream pipeline 7, and the technical means of shunting and intercepting sewage achieves the technical effect of shunting and discharging the initial rainwater and/or sewage (which can be understood as dirty water) with serious pollution and the rainwater at the middle and later stages (which can be understood as clean water) with clearer pollution.

Further, referring to fig. 2D, for the filtering device 6 in the above embodiment, it may include: the rainwater and/or sewage are filtered by the filtering filler 603 after entering from a first water inlet of the outer barrel 601, so that the filtered rainwater and/or sewage enters a first downstream pipeline through a second water inlet arranged on the inner barrel 602. Wherein, the filter filler 603 is made of an elastic compressible material, such as: filtering cotton and sponge; compared with the solid filling materials such as gravel, zeolite, quartz sand, alumina, activated carbon, perlite and the like in the prior art, the composite material has the advantage of light weight.

In the first embodiment, the elastic filtering filler 603 is arranged in the clamping cavity between the inner barrel 602 and the outer barrel 601 to filter the rainwater and/or sewage entering the outer barrel 601, and the weight of the filtering device 6 can be greatly reduced because the filtering filler 603 is made of the elastic material; therefore, compared to the prior art that solid filling materials such as gravel, zeolite, quartz sand, alumina, activated carbon, perlite, etc. are used, the present embodiment proposes a technical solution that the pressing plate 607 is used to extrude the filtering filler 603 with elasticity and the filtering filler 603 is restored to its original state after extrusion, so as to change the density of the filtering filler 603 and further control the filtering density of the rainwater and/or sewage passing through the filtering filler 603, therefore, the present embodiment further promotes the filtering degree of the rainwater and/or sewage on the basis of the advantage of light weight brought by the material of the filtering filler 603, in the first embodiment, the filtering device 6 further includes: a pressure plate 607 and an adjusting mechanism, the pressure plate 607 is arranged in the clamping cavity and is positioned above the filter filler 603; the adjusting mechanism is connected with the pressing plate 607, the height of the pressing plate 607 in the clamping cavity is adjusted by the adjusting mechanism, when the external water flow is small (for example, in a non-rainfall period) and the filtering requirement is high, the pressing mechanism is adjusted to control the pressing plate 607 to extrude towards the direction of the filtering filler 603, so that the density of the filtering filler 603 is increased, the density of sewage and/or rainwater passing through the filtering filler 603 is increased, and finally the filtering effect of the filtering filler 603 is improved; when the external rainwater and/or sewage flow is large (for example, in a rainfall period), the pressing mechanism is adjusted to control the pressing plate 607 to displace towards the direction away from the filtering filler 603, so that the density of the squeezed filtering filler 603 is slowly restored to the initial state, and further the density of the filtering filler 603 is controlled to be reduced, so that the filtering density of the rainwater and/or sewage passing through the filtering filler 603 is reduced, and the technical effects of quickly filtering the rainwater and/or sewage and quickly flowing into a downstream pipeline are achieved.

Based on the above embodiment in which the adjusting mechanism adjusts the pressing plate 607 to control the density of the filter filler 603, please continue to refer to fig. 2E, this embodiment provides a preferred embodiment for the adjusting mechanism, which specifically includes: a mounting plate 610 and a first screw 608, wherein the mounting plate 610 is connected to the other end of the inner cylinder 602, and the mounting plate 610 is provided with a first screw hole; the first screw 608 is screwed in the first screw hole; the end of the first screw 608 connected to the first screw hole abuts against the pressure plate 607, when the first screw 608 displaces in the direction of the filter filler 603, the first screw 608 pushes the pressure plate 607 to press the filter filler 603, so as to increase the density of the filter filler 603, and increase the filter density of the filter filler 603, so that the filter density of the filter filler 603 increases, and the filter effect becomes better, and when the first screw 608 displaces in the direction away from the filter filler 603, the filter filler 603 rebounds, so that the density of the filter filler 603 returns to the density of the original volume, thereby achieving the technical effects of rapidly filtering sewage and/or rainwater and rapidly flowing into a downstream pipeline.

Further, in order to better drive the pressing plate 607 to move up and down to avoid the defect that the pressing plate 607 cannot move back only by the elastic tension of the elastic filler due to too large gravity of the pressing plate 607, please refer to fig. 2F, this embodiment proposes an embodiment to solve the defect, and the embodiment includes: a mounting plate 610, wherein the mounting plate 610 is connected to the other end of the inner cylinder 602, the mounting plate 610 is provided with a hole, a bearing is fixed in the hole, a first screw 608 is fixed in the hole, the first screw 608 penetrates through the bearing to be in threaded connection with a pressure plate 607, and threads which are arranged on the pressure plate 607 and are matched with the first screw 608 are provided; the first screw 608 can drive the pressing plate 607 to move linearly in the clamping cavity in the forward direction or the reverse direction, so that the first screw 608 displaces in the direction away from the filter filler 603 to drive the pressing plate 607 to move away from the filter filler 603. For example, when the flow demand of rainwater or sewage increases in rainy days, the first screw 608 is adjusted to be screwed in a direction away from the filtering filler 603, so that the first screw 608 drives the pressing plate 607 to be lifted, and the filtering filler 603 is rapidly restored to its original volume, thereby achieving the technical effects of rapidly filtering the sewage and/or the rainwater and rapidly flowing into a downstream pipeline.

Specifically, as for the water outlet structure, as an implementation manner of the water outlet structure, it may be a siphon pipe 3 as shown in fig. 1, and a water inlet end of the siphon pipe 3 is disposed in the storage structure 2, and a water outlet end of the siphon pipe 3 is disposed outside the storage structure 2, when a level of rainwater collected by the storage structure 2 and flowing in from the rainwater stand pipe 1 reaches a siphon level, rainwater in the storage structure 2 flows in from the water inlet end of the siphon pipe 3 and is guided to the ground through the water outlet end thereof, so as to implement a water outlet process of rainwater stored in the storage structure 2 through the water outlet structure; it should be noted that, in the embodiment of the present application, a manner of implementing water outlet by using a siphon principle through the siphon 3 is already the prior art, and therefore, this embodiment will not be described in detail.

As another implementation manner of the water outlet structure, the water outlet structure can also be a water outlet hole, and the water outlet hole is formed at the bottom of the buffer device; it can be understood that in the implementation manner of the water outlet structure, relatively clean rainwater on the top surface of the target building 4 flows into the storage structure 2 of the buffer device through the rainwater stand pipe 1, and then the rainwater in the storage structure 2 is directly guided to the ground by the water outlet hole for natural seepage or for irrigating vegetation near the storage structure 2; it should be noted that the aperture of the water outlet is far smaller than the diameter of the vertical rainwater pipe 1, that is: the water inlet flow of the rainwater vertical pipe 1 is far greater than the water outlet flow of the water outlet hole; therefore, in the process of draining the rainwater into the storage structure 2 through the rainwater vertical pipe 1, a small amount of rainwater can be discharged from the water outlet at the bottom of the storage structure 2, and as time increases, the water level in the storage structure 2 can still continuously increase until the preset water level is reached, it can be understood that when the storage structure 2 collects and stores rainwater on the top floor of the target building 4, the water outlet can continuously guide the rainwater in the storage structure 2 to the outside of the storage structure 2, so that the time for the storage structure 2 to collect the rainwater to the preset water level is increased, further, in order to avoid continuous water outlet of the water outlet when the storage device collects the rainwater, the time for the storage structure 2 to collect the rainwater to the preset water level is slowed down, a conducting piece is arranged on the water outlet to control the conduction of the water outlet; it can be understood that in the implementation of this kind of water structure, when needs are by the apopore play water, through this circulation that switches on a control this apopore, when need not be by the apopore play water, close through this apopore of this piece control that switches on.

Further, as for the water outlet structure, the water outlet structure may further include another water outlet structure formed by combining the siphon pipe 3 and the water outlet hole, and the implementation manner of the water outlet structure includes: a siphon pipe 3 is arranged on the storage structure 2, the water inlet end of the siphon pipe 3 is arranged in the storage structure 2, the water outlet end of the siphon pipe 3 is arranged outside the storage structure 2, and when the water level of rainwater in the storage structure 2 reaches the siphon water level, the rainwater in the storage structure 2 enters from the water inlet end of the siphon pipe 3 and is guided to the ground through the water outlet end of the siphon pipe; when the water level of rainwater in the storage structure 2 does not reach the siphon water level and the rainwater in the storage structure 2 needs to be emptied, the rainwater in the storage structure 2 is discharged through the gravity of the rainwater by forming a water outlet at the bottom of the storage structure 2; when the rainwater on the top floor of the target building 4 needs to be discharged in time staggered manner with the initial rainwater on the ground, the rainwater on the top floor of the target building 4 needs to be temporarily collected and stored through the storage structure 2 in the early stage of rainfall, then when the rainwater reaches the middle and later stages of rainfall, the rainwater in the storage structure 2 is discharged to the ground and mixed and discharged with the initial rainwater on the ground, and finally the purpose of discharging the rainwater on the top floor of the target building 4 in time staggered manner with the initial rainwater on the ground is achieved, however, if the rainfall in the early stage of rainfall is large, the water level in the storage structure 2 is stored to the siphon water level when the rainwater does not transit to the middle and later stages of rainfall, so that the rainwater on the top floor of the target building 4 flows into the ground in advance to be mixed with the initial rainwater on the ground, and the preset time for shunting in time staggered manner is disturbed, the water amount on the ground is increased, the drawback of underground drainage system pressure increase, based on this, this embodiment utilizes the apopore that sets up in storage device's bottom to solve above-mentioned problem, and it should be said that, the aperture of apopore is less than 1 diameter of rainwater riser far away, promptly: the water inlet flow of the rainwater vertical pipe 1 is far greater than the water outlet flow of the water outlet hole; therefore, when the rainwater vertical pipe 1 conducts drainage into the storage structure 2, a small amount of rainwater can be discharged from the water outlet hole at the bottom of the storage structure 2, as time increases, the water level in the storage structure 2 will continue to increase, until a predetermined water level is reached, however, during the water level increase of the storage structure 2, rainwater will continuously flow out from the water outlet, and thus the time for the water level in the storage structure 2 to rise will be reduced, as will be appreciated, when the storage structure 2 collects and stores the rainwater on the top surface of the target building 4, the water outlet hole can continuously guide the rainwater in the storage structure 2 to the outside of the storage structure 2, and the water outlet flow of the water outlet hole is far smaller than the water inlet flow of the rainwater vertical pipe 1, therefore, the time for the water level in the storage structure 2 to rise to the siphon water level is only slowed down, so that the problem that the water level in the storage device flows into the ground too early due to overlarge rainfall in the early stage of rainfall is avoided; further, when the rain volume becomes less, if the rainwater in storage structure 2 still flows out from the apopore, will cause the water level in storage structure 2 can't reach the siphon water level at the predetermined time point, this embodiment one provides the implementation mode that sets up a piece that switches on the apopore, can control switching on and closing of apopore at any time through this piece that switches on.

Example two:

the second embodiment of the invention provides a method for distributing roof rainwater, which comprises the following steps: in the early stage of rainfall, collecting initial rain drainage on the top surface of the target building 4 to a buffer device for storage, and discharging the initial rain on the ground to a rainwater port 5, and shunting the initial rain to a first downstream pipeline 8 from the rainwater port 5; and in the middle and later periods of rainfall, the initial rain collected by the buffer device is discharged to the ground, so that the initial rain and the middle and later periods of rain on the ground are collected and discharged to the rainwater port 5, and are distributed to the second downstream pipeline 7 by the rainwater port 5.

In the technical scheme, the technical purpose of staggered discharge of relatively clean rainwater on the top layer of the building and relatively dirty initial rainwater on the ground is achieved by separately treating the rainwater in the early stage of rainfall and in the middle and later stages of rainfall; in the early stage of rainfall, firstly, relatively clean rainwater on the top layer surface of the target building 4 is drained and collected to the buffer device for storage, and then relatively dirty early rainwater on the ground is shunted to the first downstream pipeline 8 through the rainwater inlet 5, so that the relatively dirty early rainwater on the ground is firstly drained to the first downstream pipeline 8; in the middle and later periods of rainfall, when the rainwater in the middle and later periods on the ground is clear relative to the rainwater in the early period, the relatively clean rainwater collected by the buffer device is discharged to the ground to be mixed with the rainwater in the middle and later periods on the ground, and is discharged to a second downstream pipeline 7 together in a shunting manner through a rainwater inlet 5; it can be understood that, at the early stage of rainfall, collect the storage to the rainwater of the top floor of target building 4, and the initial rainwater on ground shunts to first downstream pipe 8 through inlet for stom water 5, in the middle and later stages of rainfall, converge the rainwater in storage structure 2 with the middle and later stages rainwater on ground, and shunt the rainwater after converging to second downstream pipe 7 through inlet for stom water 5, so as to realize separately discharging the rainwater on roof and the initial rainwater on ground, reach the technical purpose of discharging the reposition of redundant personnel in a staggered time, in order to solve the old district because of the limited road surface ponding's that leads to of underground pipe network hydrophobic ability technical problem.

Specifically, for the method of collecting the rainwater drainage on the top floor of the target building 4 to the buffer device for buffering, it may communicate with the top floor of the target building 4 through a rainwater riser 1, so that the initial rainwater on the top floor of the target building 4 is collected into the storage structure 2 through the rainwater riser 1 for storage, which may be implemented as follows: in the early stage of rainfall, comparatively clean rainwater on the top deck of target building 4 is drained to storage structure 2 through rainwater riser 1 and temporarily stored, and then distinguishes technical effect with the dirty early stage rainwater on ground.

Another implementation method for collecting rainwater drainage on the top floor of the target building 4 to the buffer device for buffering can be realized by communicating the storage structure 2 through a siphon 3, so that a water inlet end of the siphon 3 is arranged in the storage structure 2, and a water outlet end of the siphon 3 is arranged outside the storage structure 2, when the rainwater level collected by the storage structure 2 and flowing in from the rainwater stand pipe 1 reaches a siphon water level, rainwater in the storage structure 2 flows in from the water inlet end of the siphon 3 and is guided to the ground through the water outlet end thereof, so that a rainwater outlet process of the rainwater stored in the storage structure 2 is realized through the water outlet structure; it should be noted that, in the embodiment of the present application, a manner of implementing water outlet by using a siphon principle through the siphon 3 is already the prior art, and therefore, this embodiment will not be described in detail.

In another implementation method for draining and collecting rainwater on the top floor of the target building 4 to the buffer device for buffering, a water outlet hole is formed in the bottom of the storage structure 2, so that initial rainwater flowing into the storage structure 2 from the rainwater stand pipe 1 flows to the ground under the action of gravity of the initial rainwater, and it can be understood that in the implementation manner of the water outlet structure, relatively clean rainwater on the top floor of the target building 4 flows into the storage structure 2 of the buffer device through the rainwater stand pipe 1, and then the rainwater in the storage structure 2 is directly guided to the ground by the water outlet hole for natural leakage or for irrigating vegetation near the storage structure 2; it should be noted that the aperture of the water outlet is far smaller than the diameter of the vertical rainwater pipe 1, that is: the water inlet flow of the rainwater vertical pipe 1 is far greater than the water outlet flow of the water outlet hole; therefore, in the process of draining the rainwater into the storage structure 2 through the rainwater vertical pipe 1, a small amount of rainwater can be discharged from the water outlet at the bottom of the storage structure 2, and as time increases, the water level in the storage structure 2 can still continuously increase until the preset water level is reached, it can be understood that when the storage structure 2 collects and stores rainwater on the top floor of the target building 4, the water outlet can continuously guide the rainwater in the storage structure 2 to the outside of the storage structure 2, so that the time for the storage structure 2 to collect the rainwater to the preset water level is increased, further, in order to avoid continuous water outlet of the water outlet when the storage device collects the rainwater, the time for the storage structure 2 to collect the rainwater to the preset water level is slowed down, a conducting piece is arranged on the water outlet to control the conduction of the water outlet; it can be understood that in the implementation of this kind of water structure, when needs are by the apopore play water, through this circulation that switches on a control this apopore, when need not be by the apopore play water, close through this apopore of this piece control that switches on.

Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
