Technical Field

The invention relates to the field of fluid power, in particular to a novel efficient fluid driving device.

Background

The breadth of our country is wide and the topography is complex. In mountain cities, a plurality of dispersed small and medium-sized sewage treatment stations have terrain drops, and the sewage potential energy can be used for driving rotary sewage treatment devices such as biological rotating cages, biological rotating discs and the like to realize the processes of mixing, oxygenating and the like, thereby saving the operation energy consumption and realizing the low energy consumption and even zero energy consumption removal of pollutants.

At present, the traditional biological rotating disk is driven by a trough body or a fan blade, namely, the trough body or the fan blade is arranged on the circumferential side surface of the rotating disk, a high water source impacts the trough body or the fan blade, the trough body or the fan blade is impacted by water to rotate the rotating disk, and the potential energy of the water is converted into the kinetic energy of the rotating disk. However, since the lower half part of the turntable is located in water, when the turntable rotates, the back of the tank body or the back of the fan blade on the turntable can be subjected to the resistance of water, so that the kinetic energy of the turntable is lost to a certain extent, and the kinetic energy conversion rate of the fluid still needs to be further improved.

Disclosure of Invention

The invention aims to provide a novel high-efficiency fluid driving device to reduce the loss of kinetic energy of a rotary disc.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a novel high-efficient fluid drive device, includes the carousel, and the circumference distributes on the carousel has a plurality of drive groove, is equipped with the water inlet on the drive groove, is equipped with the delivery port on the bottom in drive groove, and swing joint has the valve on the bottom in drive groove, and one side of carousel is the drive side, and the opposite side of carousel is non-drive side, and the valve that the carousel rotated the in-process and is located the drive groove of drive side is in the closed condition, and the valve that is located the drive groove of non-drive side is in the open condition.

The working principle and the effect of the scheme are as follows: the driving side is the side where water flowing down from a high place impacts the driving groove, and the non-driving side is the side where the driving groove on the turntable cannot be impacted by the water flowing down from the high place. In this scheme, the carousel drive side is because the valve is in the state of closing, and the delivery port in drive groove is closed, consequently can block eminence downflow water, and downflow water will stop in the drive groove, relies on the gravity of water to provide drive power to make the carousel rotate. And along with the pivoted going on, the driving groove slope and pour out liquid, when the driving groove on the carousel rotated the non-drive side of carousel, the valve was in the state of opening, the delivery port in driving groove was opened, water inlet and delivery port intercommunication, the area of driving groove bottom and water contact reduces like this, the bottom in the driving groove of non-drive side receives the resistance under water and reduces, thereby can prevent that the carousel from receiving great resistance under water and making carousel kinetic energy loss great because of the bottom in driving groove, do benefit to and make the carousel rotate, fluid kinetic energy, the conversion rate of potential energy to carousel kinetic energy conversion has been improved.

Furthermore, one end of the valve is rotatably connected to the bottom of the driving groove, and the other end of the valve is abutted to the bottom of the driving groove. Thus, the advantages of the shutter design are: when the drive groove rotates to the bottom of the rotary disc, the valve can automatically rotate and automatically open under the thrust of water and the action of the gravity of the valve, and the contact area of the bottom of the drive groove and the water is reduced, so that the resistance of liquid to the rotation of the rotary disc can be automatically reduced. When the driving groove rotates to the top of the rotary disc, the valve rotates reversely under the action of self gravity to automatically close the water outlet, so that the valve is automatically closed, the driving groove on the driving side can contain certain liquid, and the rotary disc normally rotates.

Furthermore, a push block is connected to the valve in a sliding mode, a push rod is connected to the push block in a rotating mode, the push rod penetrates through the drive groove and is connected to one side, away from the turntable, of the drive groove in a sliding mode, a first magnetic sheet is fixedly connected to the end portion, abutted to the bottom of the drive groove, of the valve, and a second magnetic sheet which is mutually exclusive with the first magnetic sheet is fixedly connected to the bottom of the drive groove. From this, when the drive slot rotated the bottom of carousel, push rod and ejector pad slided downwards under the effect of gravity, and the push rod does not block the valve, and the valve is opened under the effect of the repulsion of first magnetic sheet and second magnetic sheet, and when the valve was opened in this scheme, first magnetic sheet and second magnetic sheet repelled each other for the valve was opened more easily. When the driving groove rotates to the top of the rotary disc, the push rod and the push block move downwards under the action of gravity, the push rod pushes the push block to move downwards, the push block pushes the valve to close the valve by overcoming the repulsive force between the first magnetic sheet and the second magnetic sheet, and the push rod is inserted into the driving groove at the moment, so that the valve can be prevented from being opened by the repulsive force between the first magnetic sheet and the second magnetic sheet.

Furthermore, a plurality of groove cavities distributed circumferentially are arranged on the circumferential side surface of the rotary table, the driving groove is connected in the groove cavities in a radial sliding manner, and a control mechanism for controlling the driving groove to slide in the groove cavities is arranged on the rotary table. The slot cavity may be adapted to receive a drive slot. Therefore, whether the driving grooves slide out of the groove cavities or not can be controlled through the control mechanism, so that the number of the driving grooves on the outer side of the rotary table can be controlled, when the number of the driving grooves is large, the total volume of liquid in the driving grooves on the driving side of the rotary table is large, the gravity of water in the driving grooves is increased, and the rotating speed of the rotary table is increased; when the number of the driving grooves is small, the total volume of liquid in the driving groove on the driving side of the turntable is correspondingly reduced, the gravity of water in the driving groove is reduced, and the rotating speed of the turntable is reduced. From this, can realize the regulation of carousel rotational speed through this scheme to the demand of different carousel output rotational speeds is adapted to.

Further, control mechanism includes the control shaft, the control shaft traversing and sliding connection are on the centre of a circle position of carousel, a plurality of first magnetic stripes of fixedly connected with on the side of control shaft, second magnetic stripe and third magnetic stripe, first magnetic stripe, second magnetic stripe and third magnetic stripe all include attraction section and repulsion section, the length of the attraction section of first magnetic stripe, the length of the attraction section of second magnetic stripe and the length of the attraction section of third magnetic stripe grow gradually, the length of the repulsion section of first magnetic stripe, the length of the repulsion section of second magnetic stripe and the length of the repulsion section of third magnetic stripe shorten gradually, equal fixedly connected with magnet on the position that the drive groove is located the vallecular cavity, magnet repels with the repulsion section, magnet and attraction section attract mutually. Therefore, in the sliding process of the control shaft relative to the rotating disc, the relative position of the magnet relative to the repelling section and the attracting section can be changed, and the magnet can be opposite to the corresponding number of attracting sections or repelling sections in the moving process of the control shaft due to the fact that the length of the attracting section of the first magnetic strip, the length of the attracting section of the second magnetic strip and the length of the attracting section of the third magnetic strip are different, and the length of the repelling section of the first magnetic strip, the length of the repelling section of the second magnetic strip and the length of the repelling section of the third magnetic strip are different. In the moving process of the control shaft, when the magnets attract all the attraction sections, the magnets on all the driving grooves are attracted by the corresponding magnets and the attraction sections to enter the groove cavities, the number of the driving grooves on the outer side of the turntable is zero, and the turntable cannot rotate; along with the movement of the control shaft, when the driving groove corresponding to the first magnetic strip is opposite to the repelling section and the driving grooves corresponding to the second magnetic strip and the third magnetic strip are still opposite to the attracting section, the repelling section of the first magnetic strip repels the driving groove corresponding to the first magnetic strip, so that the driving groove corresponding to the first magnetic strip extends out of the groove cavity of the turntable; with the continuous movement of the control shaft, when the driving grooves corresponding to the first magnetic strip and the second magnetic strip are opposite to the corresponding repelling sections and the driving groove corresponding to the third magnetic strip is attracted to the attracting section, the magnets corresponding to the driving grooves on the second magnetic strip are subjected to the repelling force of the corresponding repelling sections and extend out of the groove cavity of the turntable, so that the number of the driving grooves outside the turntable is increased; as the control shaft continues to move, the magnets on the driving grooves are opposite to all the repelling segments, so that the magnets opposite to the driving grooves on the third magnetic strip are subjected to the repelling force of the corresponding repelling segments to extend out of the groove cavity of the turntable, and the number of the driving grooves on the outer side of the turntable is further increased. Therefore, the number of the driving grooves on the outer side of the rotary table is controlled through the control shaft, and the operation is simple and convenient.

Furthermore, control mechanism still includes promotes axle, handle bar and bearing, promotes axle fixed connection and circles in the bearing, promotes the tip fixed connection of axle and circles on the tip of control shaft, handle bar fixed connection is on the outer lane of bearing. From this, can promote bearing lateral shifting through the handlebar stem, the bearing drives control shaft lateral shifting through promoting the axle again, can realize the lateral shifting of control shaft through controlling of handlebar stem promptly, and then can realize the control of the drive groove quantity in the carousel outside, easy operation is convenient. The pushing shaft is connected with the handle rod through the bearing, so that the pushing shaft cannot drive the handle rod to rotate when the pushing shaft rotates.

Further, be equipped with the pole chamber with the vallecular cavity intercommunication on the carousel, the pole chamber radially sets up along the carousel, fixedly connected with catch bar on the drive groove, catch bar sliding connection is in the pole chamber, and magnet fixed connection is on the tip that the drive groove was kept away from to the catch bar. Therefore, the magnet is positioned on the end part of the push rod, and is closer to the control shaft than the magnet is positioned on the driving groove, so that the sensitivity of the magnet to the magnetic force can be improved.

Further, the shutter is rotatably connected to the bottom of the driving groove through a hinge. Therefore, the bottom of the valve and the bottom of the driving groove are rotatably connected, and the hinge connection is a common rotating connection mode.

Furthermore, a rotating shaft is coaxially and fixedly connected to the rotating disc. The rotation of the rotary disc can be output to the outside through the rotating shaft.

Furthermore, the end part of the push rod, far away from the push block, is fixedly connected with a first magnet block, a second magnet block mutually repelling with the first magnet block is arranged above the rotary disc, and a third magnet block mutually attracting with the first magnet block is arranged below the rotary disc. From this setting, when the drive slot rotated the below of carousel, the third magnet piece attracted first magnet piece to exert external magnetic force for the push rod, compare the push rod and move down under the effect of gravity alone, be favorable to the push rod to move down more, make the valve can further smooth opening. In a similar way, when the drive slot rotated the top of carousel, the second magnet piece rejected first magnet piece, compares the push rod and moves down under the effect of gravity alone, is favorable to the push rod to move down more for the valve can be further smooth the closing.
