DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 7 As shown, the embodiment of the present invention provides a water conservancy project gate structure, including a valve body 1, a water outlet 15 is opened on the top of the valve body 1, a first flange 3 is fixedly installed on the top of the water outlet 15, a water inlet pipe 2 is fixedly installed on the right side of the valve body 1, a driving chamber 4 is fixedly installed on the bottom of the valve body 1, a guide cylinder 18 is fixedly installed inside the valve body 1, and a valve stem 19 is movably installed inside the guide cylinder 18;

[0030] A second flange 5 is placed on the top of the first flange 3, and the first flange 3 and the second flange 5 are fixedly connected by bolts. A filter bin 6 is fixedly installed on the top of the second flange 5, a connecting pipe 7 is fixedly installed on the left side of the filter bin 6, a filter cartridge 8 is movably installed inside the filter bin 6, a first spring 9 is arranged between the top of the filter cartridge 8 and the filter bin 6, a movable plate 16 is fixedly installed on the bottom of the filter cartridge 8, the movable plate 16 abuts against the water outlet 15 through the elastic potential energy of the first spring 9, a guide groove 10 is opened on the top outer wall of the filter cartridge 8, a guide block 11 is fixedly installed on the inner wall of the filter bin 6, and one end of the guide block 11 is movably installed inside the guide groove 10.

[0031] When it is necessary to use the valve to control the water flow, the staff will first install the device. At this time, the water flow will enter the interior of the valve body 1 from the water inlet pipe 2. However, at this time, the water outlet 15 is blocked by the valve core 17, and the valve is closed. Then the staff starts the motor 20, and the output shaft of the motor 20 drives the gear 21 to rotate. The gear 21 and the valve stem 19 are meshed with each other through the teeth 23, so that the rotation of the gear 21 drives the valve stem 19 to move downward along the guide cylinder 18. Further, the valve core 17 moves downward along the guide cylinder 18 synchronously, and the water outlet 15 is opened. The water flow will enter the inside of the water outlet 15, and as the water level rises, the movable plate 16 is pushed up by the water pressure, and when the movable plate 16 moves upward, the filter cartridge 8 will also move upward. At this time, the first spring 9 is compressed, and when the filter cartridge 8 moves, since the outer wall of the filter cartridge 8 begins to have a guide groove 10, the inside of the filter bin 6 A guide block 11 is fixedly installed so that the filter cartridge 8 rotates along the inclined direction of the guide groove 10 when it is lifted. At this time, the first spring 9 is compressed. When the filter cartridge 8 cannot continue to rise, the water flow will lift the plug 13 upward and further enter the interior of the filter cartridge 8 from the water inlet hole 12. The water flows through the filter cartridge 8 and is discharged from the connecting pipe 7. After a single drainage operation is completed, the staff resets the valve core 17 and further closes the valve. The movable plate 16 that loses the water flow squeeze will reset downward by the elastic potential energy of the first spring 9, and the plug 13 will block the water inlet hole 12 by the elastic potential energy of the second spring 14. When the filter cartridge 8 is reset, the guide block 11 will move to the bottom along the vertical groove of the guide groove 10, thereby completing the filtering function. In addition, during each drainage, the filter cartridge 8 will move upward and rotate, so that each filtering surface of the filter cartridge 8 can be fully utilized.

[0032] Through the setting of the filter cartridge 8, when the water outlet 15 is opened, the water flow will lift and rotate the filter cartridge 8, and then the water flow enters the interior of the filter cartridge 8 for filtration. Through the modular design of the filter chamber 6 and the valve body 1, the filter chamber 6 can be easily disassembled, which is convenient for cleaning the filter cartridge 8. Compared with the traditional device, the device can filter the water flow and then discharge it, which effectively guarantees the quality of the water flow, and each time the water is drained, the filter cartridge 8 will rotate slightly, thereby ensuring that the filtering surface of the filter cartridge 8 can be fully used, preventing the filter cartridge 8 from being blocked, and reducing the cleaning burden of the staff.

[0033] The bottom of the guide cylinder 18 penetrates into the interior of the driving chamber 4, and a sealing block 22 is fixedly installed at the bottom of the guide cylinder 18. The bottom of the valve stem 19 penetrates below the sealing block 22, and the outer wall of the valve stem 19 is provided with teeth 23.

[0034] A motor 20 is fixedly installed inside the driving compartment 4 , a gear 21 is fixedly installed on the output shaft of the motor 20 , and the gear 21 and the valve stem 19 are transmission-connected via teeth 23 .

[0035] Water will flow into the interior of the valve body 1 from the water inlet pipe 2. However, at this time, the water outlet 15 is blocked by the valve core 17, and the valve is closed. Then the staff starts the motor 20. The output shaft of the motor 20 drives the gear 21 to rotate. The gear 21 and the valve stem 19 are meshed with each other through the teeth 23, so that the rotation of the gear 21 drives the valve stem 19 to move downward along the guide cylinder 18. Further, the valve core 17 moves downward along the guide cylinder 18 synchronously, the water outlet 15 is opened, and water will flow into the interior of the water outlet 15.

[0036] Through the operation of the motor 20, the gear 21 drives the valve stem 19 to move up and down along the guide cylinder 18 through the teeth 23, and further moves the valve core 17 up and down to realize the opening and closing of the valve. Compared with the traditional device, the device can accurately control the movement path of the valve core 17, thereby realizing the adjustment of the water flow size, which can effectively meet the needs of water conservancy construction and ensure work efficiency.

[0037] Among them, a fixing groove 27 is opened on the outer wall of the connecting pipe 7, and a water outlet pipe 24 is detachably installed on the connecting pipe 7. A telescopic groove 26 is opened on the outer wall of the water outlet pipe 24. The positions of the telescopic groove 26 and the fixed groove 27 correspond to each other. A fixing block 28 is movably installed inside the telescopic groove 26. The bottom of the fixing block 28 and the telescopic groove 26 are elastically connected by a fourth spring 29, and the fixing block 28 penetrates into the interior of the fixed groove 27.

[0038] When it is necessary to clean the filter cartridge 8 inside the filter bin 6, the staff first presses the fixing block 28. At this time, the fourth spring 29 is compressed and the fixing block 28 is received into the telescopic groove 26. The fixing relationship between the water outlet pipe 24 and the connecting pipe 7 is released. Subsequently, the elastic potential energy of the third spring 25 will pop the water outlet pipe 24 outward, thereby removing the water outlet pipe 24. Then the staff unscrews the bolts between the second flange 5 and the first flange 3 to disassemble the filter bin 6 as a whole. When it is necessary to reinstall, the staff aligns the fixing block 28 and the fixing groove 27 at the right end of the water outlet pipe 24 with each other, and then inserts the water outlet pipe 24 into the connecting pipe 7. At this time, the shape design of the fixing block 28 makes the fixing block 28 squeezed into the telescopic groove 26 by the inner wall of the connecting pipe 7. After the telescopic groove 26 and the fixing groove 27 are aligned, the fixing block 28 is reset by the elastic potential energy of the fourth spring 29, thereby completing the installation between the water outlet pipe 24 and the connecting pipe 7.

[0039] By pressing the fixing block 28 so that the fixing block 28 is stored in the telescopic groove 26, the fixing relationship between the water outlet pipe 24 and the connecting pipe 7 is released, and the water outlet pipe 24 is popped outward by the elastic potential energy of the third spring 25, so that the water outlet pipe 24 is disassembled. Compared with the traditional device, after the filter bin 6 is installed, the connecting pipe 7 and the water outlet pipe 24 can be easily and quickly connected, which reduces the workload and improves the work efficiency.

[0040] A water inlet hole 12 is fixedly mounted on the top of the movable plate 16 , and the water inlet hole 12 is located inside the filter cartridge 8 .

[0041] Among them, the water inlet hole 12 and the water outlet hole 15 are connected to each other, and a plug 13 is movably installed inside the water inlet hole 12. The top of the plug 13 and the water inlet hole 12 are elastically connected by a second spring 14. The plug 13 blocks the bottom of the water inlet hole 12 through the elastic potential energy of the second spring 14.

[0042] By providing the plug 13 and the second spring 14 , the water inlet 12 forms a small one-way valve to prevent impurities in the filter cartridge 8 from falling into the water inlet and outlet 15 .

[0043] The top of the guide cylinder 18 is movably sleeved with a valve core 17 , the top of the valve core 17 blocks the water outlet 15 , and the bottom of the valve core 17 is fixedly connected to the valve stem 19 .

[0044] The arrangement of the valve core 17 realizes the opening and closing function of the valve.

[0045] The rightmost end of the water outlet pipe 24 and the connecting pipe 7 are elastically connected via a third spring 25 , and the fixing block 28 abuts against the fixing groove 27 via the elastic potential energy of the third spring 25 .

[0046] The third spring 25 can not only eject the water outlet pipe 24 when it is removed, but also increase the friction between the fixing block 28 and the inner wall of the fixing groove 27 to prevent the water outlet pipe 24 from loosening.

[0047] The cross-sectional shape of the fixing block 28 is a right-angled trapezoid, and the inclined surface thereof is opened to the right.

[0048] After the staff aligns the fixing block 28 and the fixing groove 27 at the right end of the water outlet pipe 24 with each other, the water outlet pipe 24 is inserted into the connecting pipe 7. At this time, the shape design of the fixing block 28 allows the fixing block 28 to be squeezed into the telescopic groove 26 by the inner wall of the connecting pipe 7.

[0049] Working principle and usage process:

[0050] When it is necessary to use the valve to control the water flow, the staff will first install the device. At this time, the water flow will enter the interior of the valve body 1 from the water inlet pipe 2. However, at this time, the water outlet 15 is blocked by the valve core 17, and the valve is closed. Then the staff starts the motor 20, and the output shaft of the motor 20 drives the gear 21 to rotate. The gear 21 and the valve stem 19 are meshed with each other through the teeth 23, so that the rotation of the gear 21 drives the valve stem 19 to move downward along the guide cylinder 18. Further, the valve core 17 moves downward along the guide cylinder 18 synchronously, and the water outlet 15 is opened. The water flow will enter the inside of the water outlet 15, and as the water level rises, the movable plate 16 is pushed up by the water pressure, and when the movable plate 16 moves upward, the filter cartridge 8 will also move upward. At this time, the first spring 9 is compressed, and when the filter cartridge 8 moves, since the outer wall of the filter cartridge 8 begins to have a guide groove 10, the inside of the filter bin 6 A guide block 11 is fixedly installed so that the filter cartridge 8 rotates along the inclined direction of the guide groove 10 when it is lifted. At this time, the first spring 9 is compressed. When the filter cartridge 8 cannot continue to rise, the water flow will lift the plug 13 upward and further enter the interior of the filter cartridge 8 from the water inlet hole 12. The water flows through the filter cartridge 8 and is discharged from the connecting pipe 7. After a single drainage operation is completed, the staff resets the valve core 17 and further closes the valve. The movable plate 16 that loses the water flow squeeze will reset downward by the elastic potential energy of the first spring 9, and the plug 13 will block the water inlet hole 12 by the elastic potential energy of the second spring 14. When the filter cartridge 8 is reset, the guide block 11 will move to the bottom along the vertical groove of the guide groove 10, thereby completing the filtering function. In addition, during each drainage, the filter cartridge 8 will move upward and rotate, so that each filtering surface of the filter cartridge 8 can be fully utilized.
