Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment: As Figures 1-12As shown in the figure, the present invention provides a technical solution for a sewage and sludge filtering and water purification device for a water conservancy project gate, including a dam 1 and a gate structure. The gate structure includes a gate passage 2 fixedly penetrated on the dam 1, an opening and closing assembly installed on the gate passage 2, a filter net 7 arranged on one side of the opening and closing assembly, a collection box 8 arranged on one side of the filter net 7, and a metal net 9 fixedly installed on one side inside the collection box 8. A plurality of expansion members 13 are fixedly installed inside the collection box 8. A gate valve 11 and a position control assembly are installed on the top of the collection box 8. The collection box 8 is formed with a diversion cavity 10, and the diversion cavity 10 communicates with the plurality of expansion members 13. The gate valve 11 is fixedly installed on the top of the collection box 8 and communicates with the inside of the diversion cavity 10. A diversion elbow 12 is fixedly installed on the top of the gate valve 11. A sealing plate 29 is fixedly installed at the bottom of the collection box 8. A sewage discharge groove 30 is opened at the bottom of the inner cavity of the gate passage 2. A high-pressure water pipe 31 is arranged between the filter net 7 and the opening and closing assembly. A plurality of high-pressure nozzles 32 are fixedly installed on the outer side of the high-pressure water pipe 31. A cleaning assembly is arranged between the high-pressure nozzles 32 and the opening and closing assembly.

[0022] Specifically, the mounting frame one 6 in the opening and closing assembly is fixedly inserted into the gate passage 2. The gate plate 5 penetrated inside the mounting frame one 6 is slidably connected with the gate passage 2. The gate plate 5 can only move up and down inside the gate passage 2. A hydraulic cylinder one 3 and two telescopic rods one 4 are fixedly installed between the gate plate 5 and the dam 1. The two telescopic rods one 4 further support and limit the gate plate 5. The gate plate 5 can only move up and down. By controlling the telescopic rod one 4 to work, the gate plate 5 moves upward, reducing the volume of the gate plate 5 inside the gate passage 2, connecting the waters on both sides of the dam 1, and enabling water to flow through the gate passage 2.

[0023] Specifically, a filter net 7 is arranged on one side of the gate plate 5. The filter net 7 is fixedly connected with the gate passage 2. The filter net 7 and the collection box 8 arranged on one side of the filter net 7 are located upstream of the water area. The filter net 7 filters and purifies the water entering the downstream water area through the gate passage 2. An inlet slot 45 is opened on one side of the collection box 8 close to the filter net 7. The position of the filter net 7 near the gate plate 5 is higher, and the position of the filter net 7 far from the gate plate 5 is lower. The filter net 7 is inclined. The contact end of the collection box 8 with the filter net 7 is an inclined surface, and the collection box 8 is attached to the filter net 7. Therefore, the impurities and mud intercepted by the filter net 7 move through the inlet slot 45 under the action of gravity and enter the inside of the collection box 8, collecting the mud and impurities intercepted by the filter net 7, which is convenient for subsequent collection and treatment of the impurities.

[0024] Specifically, a diversion chamber 10 is formed on the collecting box 8, and a plurality of expansion members 13 fixedly installed inside the collecting box 8 are all connected to the diversion chamber 10, and a gate valve 11 fixedly installed on the top of the collecting box 8 is connected to the inside of the diversion chamber 10, and a diversion elbow 12 is fixedly installed on the top of the gate valve 11, and the open end of the diversion elbow 12 faces downward to prevent the diversion elbow 12 arranged inside the gate 2 from being blocked by impurities. After the gate valve 11 is opened, liquid is infused into the diversion chamber 10 through the diversion elbow 12 and the gate valve 11, and the liquid is diverted by the diversion chamber 10 to the interior of the plurality of expansion members 13, and the plurality of expansion members 13 expand. After expansion, the plurality of expansion members 13 are all inclined, and the plurality of expansion members 13 are used to support and hook impurities such as plastic bags, ropes, and rubber sheets that enter the collecting box 8 to prevent them from being discharged through the holes in the metal mesh 9; a metal mesh 9 fixedly installed on one side inside the collecting box 8 blocks large-volume impurities to prevent large-volume impurities in the water flow from entering the collecting box 8.

[0025] Specifically, two guide grooves 15 are provided on both sides inside the gate 2, and guide plates 14 are provided inside the four guide grooves 15 with the same inclination angle as the filter screen 7. The guide plates 14 are fixedly installed on the outside of the collecting box 8. Under the limit of the guide plates 14 and the guide grooves 15, the telescopic rod 4 moves according to the preset inclination trajectory. The outside of the filter screen 7 is cleaned during the movement of the collecting box 8. The maintenance work of the filter screen 7 can be completed during the collection of impurities inside the collecting box 8, thereby reducing the labor cost investment. A positioning bracket 28 is fixedly installed on the top of the collecting box 8.

[0026] Specifically, the metal rope 16 in the position control component is fixedly installed on the top of the collection box 8, and the forward and reverse motor 22 and the brake 24 are fixedly installed inside the equipment installation box 21 fixedly installed on the dam 1. The take-up frame 23 fixedly installed on the outer side of the output shaft of the forward and reverse motor 22 is fixedly connected to the end of the metal rope 16 inserted into the equipment installation box 21, so the forward and reverse motor 22 is controlled to work forward or reverse, so that the take-up frame 23 rotates clockwise or counterclockwise, and the metal rope 16 is unwound. Or winding; a mounting frame 17 is fixedly installed on a supporting roller 18 arranged on the outside of the metal rope 16, and a hydraulic cylinder 19 and two telescopic rods 20 are fixedly installed between the mounting frame 17 and the equipment installation box 21. Under the support of the hydraulic cylinder 19 and the telescopic rod 20 that can only perform lateral expansion and contraction, the supporting roller 18 changes the direction of the metal rope 16. When the metal rope 16 is unwound, the collection box 8 moves downward under the action of gravity. When the metal rope 16 is wound up, the collection box 8 is subjected to an upward force.

[0027] The brake 24 fixedly installed inside the equipment installation box 21 is sleeved on the outer side of the output shaft of the forward and reverse motor 22. After the forward and reverse motor 22 finishes working, the brake 24 works to limit the output shaft of the forward and reverse motor 22, and the take-up frame 23 is limited.

[0028] Specifically, a guiding frame 25 is fixedly installed on one side of the mounting frame II 17 away from the equipment installation box 21. Between the tops of two guiding vertical rods 27 passing through the guiding frame 25, a grip 26 is fixedly installed. A positioning bracket 28 is fixedly installed on the top of the collection box 8. Before the collection box 8 is lowered, after holding the grip 26, the two guiding vertical rods 27 are inserted into the positioning bracket 28 after passing through the guiding frame 25. The bottom end of the guiding vertical rod 27 is in an interference fit with the positioning bracket 28. The speed of the unwinding of the first metal rope 16 is controlled. Also, because the positioning bracket 28 is relatively inclined at the top of the positioning bracket 28, under the action of the positioning bracket 28, the collection box 8 limited and guided by the guiding vertical rod 27 moves horizontally after maintaining a certain inclination angle, so that the bottom surface of the collection box 8 is parallel to the top of the right end of the gate channel 2, and the guiding plate 14 fixedly installed on the collection box 8 can enter the guiding groove 15 opened in the gate channel 2. During the process of controlling the forward and reverse motor I 22 to work and unwind the first metal rope 16, the hydraulic cylinder II 19 is controlled to work and extend to push the mounting frame II 17, the first support roller 18, the guiding frame 25 and the two guiding vertical rods 27 to move, so that the collection box 8 moves to adjust the relative position between the collection box 8 and the gate channel 2. Finally, the guiding plate 14 enters the guiding groove 15, the collection box 8 enters the gate channel 2, and the sealing plate 29 fixedly installed on the collection box 8 enters the sewage discharge groove 30 opened in the gate channel 2, and the collection box 8 can be quickly installed into the gate channel 2, completing the installation and disassembly work of the collection box 8.

[0029] Specifically, the sealing box 33 in the cleaning assembly is rotatably sleeved on the outer side of the high-pressure water pipe 31. A forward and reverse motor II 34 is fixedly installed inside the sealing box 33 fixedly connected to the inner wall of the gate channel 2. A first transmission gear 35 fixedly installed on the outer side of the output shaft of the forward and reverse motor II 34 meshes with a second transmission gear 36. The second transmission gear 36 is fixedly installed on the outer side of the high-pressure water pipe 31. Therefore, by controlling the forward or reverse rotation of the forward and reverse motor II 34, under the action of the first transmission gear 35 and the second transmission gear 36, the high-pressure water pipe 31 rotates clockwise or counterclockwise, so that a plurality of high-pressure nozzles 32 fixedly installed on the outer side of the high-pressure water pipe 31 rotate, controlling the orientation of the high-pressure nozzles 32; ​Moreover, two wire reels II 37 fixedly installed on the outer side of the high-pressure water pipe 31 are both fixedly installed with wire ropes II 38. When the high-pressure water pipe 31 rotates clockwise or counterclockwise, the wire ropes II 38 are unreeled or reeled in; and a weight-increasing frame 42 is fixedly installed at the top of a scraper 43 arranged on one side of the gate plate 5 close to the filter net 7. One ends of the two wire ropes II 38 both penetrate through the scraper 43 and the weight-increasing frame 42 and are fixedly connected to the top of the weight-increasing frame 42. A supporting roller III 41 is arranged inside an installation cavity 40 opened at the top of the gate channel 2. The supporting roller III 41 fixedly connected to the gate channel 2 changes the direction of the wire rope II 38. A supporting roller II 39 on the outer side of the wire rope II 38 is fixedly installed at the bottom of the inner cavity of the gate channel 2. Under the action of the supporting roller III 41 and the supporting roller II 39, when the wire rope II 38 is unreeled, the scraper 43 quickly moves downward under the action of the weight-increasing weight-increasing frame 42, and when the wire rope II 38 is reeled in, the scraper 43 moves upward.

[0030] Two guiding tracks 44 penetrated through on both sides of the scraper 43 are fixedly installed inside the dam 1. Under the action of the guiding tracks 44, the scraper 43 can only move downward.

[0031] In this application, the specific application method of the gate structure is as follows: Embodiment 1: After the control hydraulic cylinder I 3 works to drive the gate plate 5 to move upward, both sides of the gate channel 2 are communicated, and the water on one side of the dam 1 enters the other side of the dam 1 through the gate channel 2.

[0032] During the process of water flowing inside the gate channel 2, the filter net 7 inside the gate channel 2 intercepts impurities and silt in the water. Under the action of the inclined filter net 7, the impurities and silt settle into the collection box 8 through the feeding groove 45 under the action of gravity.

[0033] When the water discharge is completed and the inside of the gate channel 2 enters a waterless state, the control hydraulic cylinder I 3 works to push the gate plate 5 downward, the gate channel 2 is cut off, and then the control forward and reverse motor II 34 works to drive a plurality of high-pressure water pipes 31 to rotate clockwise. A plurality of high-pressure nozzles 32 fixedly installed on the outer side of the high-pressure water pipes 31 face the filter net 7, completing the preparation work for impurity and silt separation.

[0034] Subsequently, high-pressure water flow is input into the high-pressure water pipes 31. The high-pressure water flow dredges the filter net 7 and enters the collection box 8. Objects such as small silt particles and stones inside the collection box 8 that can pass through the holes in the metal net 9 leave the inside of the collection box 8. A plurality of expansion members 13 fixedly installed inside the collection box 8 and in an expanded state are all inclined. The staggered plurality of expansion members 13 support and hook impurities such as plastic bags, ropes, and rubber sheets entering the collection box 8, separating the polluting impurities from the sludge. Subsequently, the control forward and reverse motor II 34 rotates forward for a period of time and then reverses for a period of time, and repeats multiple times, so that the high-pressure nozzles 32 rotate reciprocally within a certain angle to dredge and maintain the filter net 7, completing the dredging and maintenance work of the filter net 7.

[0035] Subsequently, control the positive and negative motor 1 22 to work and wind up the metal rope 1 16, applying an upward force to the collection box 8. At the same time, control the hydraulic cylinder 2 19 to contract to control the position of the mounting frame 2 17, so that the upward force applied by the metal rope 1 16 to the collection box 8 becomes an inclined upward force. The upward force received by the collection box 8 is approximately the same as the inclination angle of the guide plate 14. The collection box 8 moves upward and one side of the bottom of the collection box 8 fits against the filter screen 7. During the upward movement of the collection box 8, the outside of the filter screen 7 is cleaned. When the collection box 8 leaves the inside of the gate channel 2, since the metal rope 1 16 is fixedly installed at one end of the top of the collection box 8 close to the feed slot 45, the collection box 8 inclines under the action of gravity, and the end of the collection box 8 where the metal mesh 9 is installed inside enters the lower state to prevent impurities inside the collection box 8 from falling; Under the action of the positive and negative motor 1 22 and the hydraulic cylinder 2 19, after the collection box 8 moves upward, the collection box 8 approaches the dam 1. The staff can carry the collection box 8 to the top of the dam 1, and then open the gate valve 11. The pressure in the diversion cavity 10 is relieved, and the expansion member 13 contracts due to pressure relief. Then, the impurities inside the collection box 8 can be easily cleaned out. Through the settings of structures such as the filter screen 7, the collection box 8, the high-pressure water pipe 31, multiple high-pressure nozzles 32, the cleaning component, the position control component, and the gate valve 11, the water flowing inside the gate channel 2 is filtered and purified, and impurities such as plastic bags, ropes, and rubber sheets that cause pollution can be separated from the sludge. The impurities that pollute the water area can be fished out to ensure the effect of water filtration.

[0036] Embodiment 2: After the inside of the collection box 8 is cleaned, the collection box 8 is suspended on one side of the dam 1. Then, hold the handle 26 and insert the two guide vertical rods 27 through the guide frame 25 and into the positioning bracket 28. The bottom end of the guide vertical rod 27 is in an interference fit state with the positioning bracket 28. Control the unwinding speed of the metal rope 1 16. Under the action of the positioning bracket 28, the collection box 8 limited and guided by the guide vertical rod 27 moves horizontally downward after maintaining a certain inclination angle. The bottom surface of the collection box 8 is parallel to the top of the right end of the gate channel 2. During the process of controlling the positive and negative motor 1 22 to work and unwind the metal rope 1 16, control the hydraulic cylinder 2 19 to work and extend to push the mounting frame 2 17, the support roller 1 18, the guide frame 25, and the two guide vertical rods 27 to move. The collection box 8 moves to adjust the relative position between the collection box 8 and the gate channel 2. Finally, the guide plate 14 enters the guide groove 15, and the collection box 8 enters the inside of the gate channel 2. The sealing plate 29 fixedly installed on the collection box 8 enters the sewage discharge groove 30 opened in the gate channel 2. The sealing plate 29 is arranged on one side of the bottom of the filter screen 7 to prevent the water that has not passed through the filter screen 7 from entering between the filter screen 7 and the gate plate 5 through the sewage discharge groove 30, completing the installation work of the collection box 8. Finally, pull up the handle 26, and the two guide vertical rods 27 are separated from the positioning bracket 28. Moreover, the collection box 8 can move only when it receives an inclined upward force, and the collection box 8 is not affected.

[0037] Embodiment 3: When the gate structure has not been used for a long time, control the forward and reverse motor two 34 to rotate forward for a period of time and then reverse for a period of time, so that the metal rope two 38 is unreeled and then reeled, and the scraper 43 moves up and down to clean one side of the gate plate 5, and at the same time, high-pressure water is conveyed into the high-pressure water pipe 31, and multiple high-pressure nozzles 32 spray high-pressure water to stir the water inside the high-pressure nozzles 32, so as to play a role in cleaning one side of the gate plate 5, avoid the attachment and growth of microorganisms when the gate plate 5 has not been used for a long time, and reduce the corrosion time of the gate plate 5; After the collection box 8 is moved up, the sealing plate 29 fixedly installed on the collection box 8 leaves the inside of the sewage discharge groove 30 opened in the gate channel 2. The sewage discharge groove 30 connects the two sides of the filter net 7. At this time, control the forward and reverse motor two 34 to rotate forward for a period of time and then reverse for a period of time again, so that the high-pressure water sprayed by multiple high-pressure nozzles 32 flushes the position of the gate channel 2 between the gate plate 5 and the filter net 7, and the sewage is discharged from the inside of the gate channel 2 through the sewage discharge groove 30, completing the cleaning and maintenance work of the gate plate 5 and slowing down the corrosion speed of the gate plate 5.
