As shown in fig. 1 to 9, the present invention provides a rainwater collecting apparatus capable of reducing wind resistance, which is installed on a trunk, and includes a guide rail 100, an umbrella collector 200, and a driving means 300.

The number of the guide rails 100 is two, the two guide rails 100 are arranged in parallel, one end of each guide rail is connected with the trunk through a connecting device, and the other end of each guide rail extends in a direction away from the trunk. .

The umbrella collector 200 is slidably mounted on two rails 100.

The driving device 300 is used for driving the umbrella collector 200 to perform reciprocating linear motion along the length direction of the guide rail 100, and when the umbrella collector 200 moves from one end of the guide rail 100 close to the trunk to one end far away from the trunk, the umbrella collector 200 is unfolded, and when the umbrella collector 200 moves from one end of the guide rail 100 far away from the trunk to one end close to the trunk, the umbrella collector 200 is folded.

Thus, in use, the rainwater collecting apparatus is located at one end of the guide rail 100 near the trunk in an initial state, and the driving apparatus 300 drives the umbrella collector 200 to move to the other end of the guide rail 100 while unfolding the umbrella collector 200 to collect rainwater in a rainy day. When the rain falls through the weather, the driving device 300 drives the umbrella collector 200 to move to the end of the guide rail 100 near the trunk and folds the umbrella collector 200. Therefore, when rainwater is collected in rainy days, the rainwater is prevented from being shielded by branches and leaves, and the collection efficiency is improved.

In one embodiment, umbrella collector 200 comprises umbrella shaft 210, runner 220, hub 230, umbrella frame 240, and canopy 250.

Wherein, one end of the umbrella shaft 210 is arranged between the two guide rails 100 and is connected with the two guide rails 100 in a sliding way, and the other end extends upwards freely.

The sliding sleeve 220 is slidably sleeved on the middle of the umbrella shaft 210 and is in threaded connection with the umbrella shaft 210, and the sliding sleeve 220 is located above the shaft sleeve 230.

The shaft sleeve 230 is sleeved on one end of the umbrella shaft 210 close to the guide rails 100 and is rotatably connected with the umbrella shaft 210, and the shaft sleeve 230 is located above the two guide rails 100 and is slidably connected with the two guide rails 100.

The number of the umbrella frames 240 is multiple, the umbrella frames 240 are evenly distributed around the axial lead of the umbrella shaft 210, the umbrella frame 240 comprises a first support 241 and a second support 242, one end of the first support 241 is hinged with the shaft sleeve 230, the other end of the first support 241 freely extends towards one side away from the umbrella shaft 210, one end of the second support 242 is hinged with the sliding sleeve 220, and the other end of the second support 242 is hinged with the first support 241.

Canopy 250 is fixedly mounted to frame 240.

The umbrella collector 200 is similar to an umbrella, but differs in that a sliding sleeve 220 is threadedly coupled to an umbrella shaft 210, and a sleeve 230 is rotatably coupled to the umbrella shaft 210, so that the sliding sleeve 220 can be moved by rotating the umbrella shaft 210 to control the unfolding and folding of the umbrella collector 200.

The umbrella collector 200 of this structure is convenient for controlling the expansion and folding thereof.

In one embodiment, the driving device 300 includes a screw 310, a slider 320, a friction wheel 330, a friction guide 340, a locking disk 350, and a driving motor.

Wherein, the screw 310 is located at the lower side of the two guide rails 100 and is rotatably connected with the guide rails 100.

The slider 320 is connected with the screw 310 by screw thread and is connected with the guide rail 100 by sliding, and the umbrella shaft 210 is installed on the top of the slider 320 and is connected with the slider 320 by rotating. Specifically, the bottom of the umbrella shaft 210 is inserted into the slider 320 and is rotatably connected to the slider 320.

The friction wheel 330 is coaxially disposed with the umbrella shaft 210 and fixedly connected with the umbrella shaft 210, and the friction wheel 330 is located at one end of the umbrella shaft 210 facing the guide rail 100 and below the guide rail 100.

The friction guide 340 is located at the bottom of one of the two guide rails 100 and is fixedly connected to the guide rail 100.

The top of the locking disc 350 is provided with a first tooth structure 351, the bottom of the shaft sleeve 230 is provided with a second tooth structure 231 matched with the first tooth structure 351, the locking disc 350 is rotatably sleeved on the umbrella shaft 210 and is positioned below the shaft sleeve 230, and the locking disc 350 is slidably connected with the two guide rails 100. Specifically, the bottom of the locking disk 350 is provided with a connecting portion 352, and the locking disk 350 is slidably engaged between the two rails 100 through the connecting portion 352, so that the locking disk 350 can only move along the rails 100 and cannot rotate with the umbrella shaft 210.

The driving motor is used for driving the screw 310 to rotate.

Thus, in use, in the initial state, the umbrella collector 200 is located at the end of the rail 100 facing the trunk.

When it rains, the driving motor drives the screw 310 to rotate in a forward direction, thereby driving the slider 320 to move along the guide rail 100 toward the end of the guide rail 100 away from the trunk.

In the process, the friction wheel 330 and the friction guide 340 are mutually matched, so that the friction wheel 330 is driven to rotate through the friction guide 340, and the umbrella shaft 210 is driven to rotate. Because the locking disk 350 is slidably captured between the rails 100 by the connecting portion 352, the locking disk 350 can only move along the rails 100 and cannot rotate with the shaft 210. The hub 230 cannot rotate with the shaft 210 due to the first and second tooth structures 351 and 231, and the rotation of the sliding sleeve 220 is limited by the umbrella frame 240, so that the sliding sleeve 220 can be moved linearly along the shaft 210 by the rotation of the shaft 210. In the process, the umbrella shaft 210 rotates in a forward direction, thereby driving the sliding sleeve 220 to move downwards, and further unfolding the rainwater collector. When the umbrella collector 200 is moved to the end of the rail 100 away from the trunk, the umbrella collector 200 is fully deployed and the friction wheel 330 and the friction rail 340 are disengaged from each other.

Similarly, when it rains on a sunny day, the driving motor drives the screw 310 to rotate in the opposite direction, so that the sliding block 320 is driven to move along the guide rail 100 to the end of the guide rail 100 close to the trunk. In the process, under the action of the friction wheel 330 and the friction guide 340, the friction guide 340 drives the friction wheel 330 to rotate reversely, so as to drive the umbrella shaft 210 to rotate reversely, so as to drive the sliding sleeve 220 to move upwards, and further fold the umbrella collector 200. When the umbrella collector 200 is positioned at the end of the rail 100 near the trunk, the umbrella collector 200 is fully collapsed and the friction wheel 330 and the friction rail 340 are disengaged from each other.

The driving device 300 with the structure converts the linear motion of the sliding block 320 into the rotation of the umbrella shaft 210 through the friction wheel 330 and the friction guide 340, thereby realizing the unfolding and folding of the umbrella-type collector 200 and having simple structure.

In one embodiment, a supporting portion 211 is fixedly disposed at one end of the umbrella shaft 210 facing the guide rails 100, the first sliding groove 110 is opened at the opposite side of the two guide rails 100, and the supporting portion 211 is slidably disposed in the first sliding groove 110. Specifically, the support portion 211 has a cylindrical shape such that the support portion 211 can rotate with the umbrella shaft 210 while moving along the guide rail 100.

This configuration facilitates support of the guide rail 100 to the umbrella collector 200.

In one embodiment, the locking device further comprises a first spring 360, a connecting portion 352 is disposed at the bottom of the locking disc 350, a limiting portion 353 is disposed at the bottom of the connecting portion 352, the locking disc 350 is slidably connected to the two guide rails 100 through the connecting portion 352, a second sliding groove 120 is disposed at one side of the two guide rails 100, the first spring 360 is sleeved on the connecting portion 352 and located in the second sliding groove 120, two ends of the first spring are respectively abutted to the limiting portion 353 and the guide rails 100, and in a natural state, the first spring 360 has a tendency of enabling the locking disc 350 to move in a direction away from the shaft sleeve 230.

The top of the supporting part 211 is provided with a first permanent magnet 212, the bottom of the locking disc 350 is provided with an electromagnet 354, the opposite side of the electromagnet 354 and the first permanent magnet 212 has the same magnetism, and one end of the two guide rails 100 far away from the trunk is provided with an accommodating groove 130.

Thus, when the umbrella collector 200 moves to the end of the rail 100 away from the trunk, the locking disk 350 moves downward by the first spring 360, so that the locking disk 350 is released from the restriction of the rotation of the bushing 230. When the driving device 300 needs to drive the umbrella collector 200 to move towards the direction close to the trunk of the tree to fold the umbrella collector 200, the electromagnet 354 is energized, and repulsion force is generated between the electromagnet 354 and the first permanent magnet 212 according to the principle that like poles repel each other, so that the locking disc 350 overcomes the elasticity of the first spring 360 and moves upwards to be matched with the shaft sleeve 230, thereby limiting the rotation thereof.

This structure facilitates the locking and unlocking of the restriction of the rotation of the hub 230, and when the locking disc 350 is unlocked from the hub 230, the umbrella collector 200 can be rotated along with the rotation of the umbrella shaft 210.

In one embodiment, a second permanent magnet 213 and an impeller 260 are also included.

The second permanent magnet 213 is fixedly sleeved on the umbrella shaft 210 and is positioned below the sliding sleeve 220, the bottom of the sliding sleeve 220 is provided with a third permanent magnet 221, and the opposite sides of the second permanent magnet 213 and the third permanent magnet 221 have opposite magnetism. Thus, when the sliding sleeve 220 moves to the position where the umbrella collector 200 is fully opened, the second permanent magnet 213 and the third permanent magnet 221 are in contact, and according to the opposite attraction, an attraction force is generated between the second permanent magnet 213 and the third permanent magnet 221, thereby limiting the movement of the sliding sleeve 220.

The number of the impellers 260 is not less than four, one end of the umbrella shaft 210, which is far away from the guide rail 100, is fixedly provided with not less than four connecting shafts, and any one of the connecting shafts is rotatably provided with the impellers 260.

Thus, when the umbrella collector 200 is opened, the locking disc 350 releases the restriction of the rotation of the sleeve 230, and the second permanent magnet 213 and the third permanent magnet 221 contact each other and generate a suction force to restrict the movement of the sliding sleeve 220, so that the whole umbrella collector 200 is rotated by the rotation of the umbrella shaft 210, thereby reducing the wind resistance.

Specifically, when wind starts, the wind drives the impellers 260 to rotate, and since a plurality of (not less than four) impellers 260 are arranged on the top of the umbrella shaft 210 around the axis thereof, the impellers 260 can rotate and also drive the umbrella shaft 210 to revolve around the axis of the umbrella shaft 210 during wind starts, thereby driving the umbrella collector 200 to rotate, and further reducing wind resistance.

In one embodiment, the umbrella further comprises a connector 400, and the umbrella shaft 210 is provided with a plurality of first water outlets 201, a plurality of second water outlets 202, and a water channel 203 for communicating the first water outlets 201 with the second water outlets 202. Specifically, the first water outlet 201 is located above the shaft sleeve 230, the second water outlet 202 is located above the friction wheel 330, the inner circumferential surface of the connector 400 is provided with an annular groove 410, the outer circumferential surface is provided with a pipeline connecting portion 420, the pipeline connecting portion 420 is communicated with the annular groove 410, the connector 400 is sleeved on the umbrella shaft 210 and located at the second water outlet 202, the connector 400 is rotatably connected with the umbrella shaft 210 and keeps sealed, and the connector 400 is communicated with the water storage tank through a water pipe.

The rainwater collected by the umbrella type collector 200 enters the water channel 203 through the first water outlet 201, then enters the annular groove 410 from the second water outlet 202, then flows into the pipeline through the pipeline connecting part 420 from the annular groove 410, and finally flows into the water storage tank from the pipeline for collection and storage.

With this structure, the connection head 400 does not affect the flow of water nor the rotation of the umbrella type collector 200.

In one embodiment, the bottom of the other of the two guide rails 100 is opened with a third sliding groove 401, and the pipe connecting portion 420 is slidably inserted into the third sliding groove 401.

This structure helps to guide and restrain the connection head 400.

The working principle of the invention is as follows:

in use, in an initial state, the umbrella collector 200 is positioned on the side of the rail 100 facing the trunk of the tree.

When raining, the driving motor drives the screw 310 to rotate in a forward direction, so that the sliding block 320 is driven to move away from the trunk of the tree, and further the umbrella collector 200 is carried together, and under the interaction of the friction wheel 330 and the friction guide 340, the linear motion of the sliding block 320 carrying the umbrella collector 200 is converted into the rotation of the umbrella shaft 210, and the umbrella shaft 210 rotates in a forward direction.

In the process, since the locking disc 350 is slidably engaged between the two rails 100 through the connecting portion 352, the locking disc 350 can only move along the rails 100 and cannot rotate with the umbrella shaft 210. The hub 230 cannot rotate with the shaft 210 due to the first and second tooth structures 351 and 231, and the rotation of the sliding sleeve 220 is limited by the umbrella frame 240, so that the sliding sleeve 220 can be moved linearly along the shaft 210 by the rotation of the shaft 210. The umbrella shaft 210 is rotated in a forward direction to drive the sliding sleeve 220 downward, thereby deploying the umbrella collector 200. When the umbrella collector 200 is completely unfolded, the second permanent magnet 213 and the third permanent magnet 221 contact each other, thereby generating an attractive force to restrict the movement of the sliding sleeve 220.

When the umbrella collector 200 is positioned at an end of the guide rail 100 away from the trunk, the locking disc 350 corresponds to the receiving groove 130, and at this time, the electromagnet 354 is not energized, so that no repulsive force is generated between the first permanent magnet 212 and the electromagnet 354, and the locking disc 350 is lowered into the receiving disc by the first spring 360, thereby releasing the locking of the rotation of the sleeve 230 while the friction wheel 330 and the friction guide 340 are separated from each other.

When wind blows, the impellers 260 rotate under the action of the wind and simultaneously drive the umbrella shaft 210 to revolve around the axis line of the umbrella shaft 210, the second permanent magnet 213 and the third permanent magnet 221 are mutually supported to generate suction force, so that the movement of the sliding sleeve 220 is limited, and meanwhile, the locking disc 350 releases the locking of the rotation of the shaft sleeve 230, so that the rotation of the umbrella shaft 210 drives the whole umbrella collector 200 to rotate through the sliding sleeve 220, and the force of the wind on the umbrella collector 200 is reduced, namely, the wind resistance is reduced.

In rainy weather, the electromagnet 354 is first energized, so that a repulsive force is generated between the first permanent magnet 212 and the electromagnet 354, and the locking disk 350 is moved upward against the elastic force of the first spring 360 until the first tooth structure 351 of the locking disk 350 is engaged with the second tooth structure 231 of the shaft sleeve 230, thereby restricting the rotation of the shaft sleeve. The driving motor drives the screw 310 to rotate reversely, and then drives the slider 320 to move in a direction approaching the trunk. Under the action of the friction wheel 330 and the friction guide 340, the umbrella shaft 210 is driven to rotate reversely, so as to drive the sliding sleeve 220 to move upwards, and further, the folding of the umbrella collector 200 is realized.

According to the rainwater collecting device capable of reducing wind resistance, when raining, the driving device 300 drives the umbrella-type collector 200 to move in the direction away from the trunk, so that the shielding of branches and leaves is avoided, the umbrella-type collector 200 is unfolded at the same time, the collecting efficiency is improved, and when the rain is rainy and sunny, the driving device 300 drives the umbrella-type collector 200 to move in the direction close to the trunk, and the umbrella-type collector 200 is folded at the same time. And the automatic folding and unfolding of the umbrella collector 200 is realized in the process that the driving device 300 drives the umbrella collector 200 to move, and the umbrella collector is simple in structure, convenient and fast.

In addition, when the rain starts, the impeller 260 is used for driving the umbrella shaft 210 to rotate, so that the umbrella type collector 200 is driven to rotate, and the wind resistance is reduced.
