[0020] 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.

[0021] See also Figure 1-Figure 7 A separate sluice pump desilting mechanism includes a dam body 1, a hydraulic cylinder 3 is installed on the dam body 1, and a sluice pump assembly 4 is connected to the output end of the hydraulic cylinder 3. A filter screen 2 is arranged on the dam body 1, and the filter screen 2 is arranged tilted. The setting of the filter screen 2 is mainly to filter some weeds or floating objects to prevent the sluice pump from being blocked by these debris, and the tilted setting can facilitate the subsequent cleaning by operators.

[0022] The gate pump assembly 4 includes a gate mechanism, a pump body device 403, a pump adjustment device and a cleaning mechanism 406; the gate mechanism includes a gate 401, which is connected to the output end of the hydraulic cylinder 3 through a connecting piece, and the middle part of the gate 401 is connected to a rotating gate 402 through an axle body, and the pump adjustment device is connected to the rotating gate 402 on the rotating gate 402 of the pump body device 403, and is used to adjust the orientation angle of the pump body device 403. The separate gate pump desilting mechanism, through the gate of a special structure, can firstly control the change of the depth of the pump body to drain water flows of different depths, and at the same time can also control the rotation of the pump body to make it rotate upward, and then directly close the gate 401, and transform it into a traditional gate 401 structure, thereby improving the diversification of the use of the gate 401, and applying it to the drainage of different water flow characteristics.

[0023] The pump regulating device includes a worm 405, which is rotatably connected to the gate 401, and one end of the worm 405 is fixedly connected to a rotating wheel 404, and a threaded tooth is provided on the rotating gate 402, and the worm 405 meshes with the threaded tooth on the rotating gate 402. The rotating wheel 404 is directly rotated, and the rotating gate 402 is driven to rotate by the rotation and engagement of the worm 405, and the rotating gate 402 will drive the pump body device 403 to convert the angle, so that the pump body device 403 is directed to waters of different depths, so as to divert water flows of different depths. At the same time, when the rotating gate 402 rotates to the limit, the entire rotating gate 402 will drive the pump body device 403 upward, and the water outlet at the tail will rotate and block the inside of the gate 401, at this time, the water flow will be cut off, and the structure of the closed gate of the traditional technology is formed as a whole, and the whole is closed.

[0024] The pump body device 403 includes a pump cover 4031, and a pump blade 4032 is arranged inside the pump cover 4031. The pump cover 4031 is rotatably connected to the inside of the rotating gate 402. One end of the pump blade 4032 is fixedly connected to a key 4034, and the key 4034 is engaged with the rotating gate 402. By rotating the pump cover 4031, the internal pump blade 4032 will be synchronously driven to rotate together, and then the key 4034 behind the pump blade 4032 will be driven to rotate in the slot 4035, rotate to the opening of the slot 4035, and then pull it outward, and the entire pump body will be pulled out, thereby realizing separation, which is convenient for the replacement and maintenance of the pump body in the later stage.

[0025] The rotating gate 402 is internally connected to a rotating gear sleeve 4033, which is provided with a slot 4035, and a key 4034 is engaged in the slot 4035. One side of the rotating gear sleeve 4033 is connected to the cleaning mechanism 406. Because the pump blade 4032 and the rotating gear sleeve 4033 are in a state of engagement, the rotating gear sleeve 4033 will be synchronously driven to rotate, and the large plate gear 4061 will be slowly driven to rotate through the meshing of the side teeth, and the flow force of the water flow is used as the power to drive the autonomous movement of the cleaning mechanism 406, thereby saving energy consumption.

[0026] The cleaning mechanism 406 includes a large disc gear 4061, which is rotatably connected to the gate 401. One side of the large disc gear 4061 is provided with teeth, which mesh with the rotating gear sleeve 4033 for transmission. A small gear 4062 is meshed below the large disc gear 4061, and a shaft 4063 is fixedly connected to the small gear 4062. Mud covers 4065 are rotatably connected to both ends of the shaft 4063. The mud cover 4065 is fixedly connected to the gate 401, and a spiral blade 4064 is fixedly connected to the shaft 4063. A conveying pipe 4067 is connected to the mud cover 4065, and an output pipe 4069 is connected to the top of the conveying pipe 4067. The rotation of the large disc gear 4061, followed by the meshing of the gears, will drive the shaft 4063 on the small gear 4062 to rotate, and the spirally structured blades 4064 on the shaft 4063 will move the silt at the bottom into the interior of the mud cover 4065. As the blades 4064 rotate, some silt will be squeezed and gradually enter the bottom of the conveying pipe 4067. The spiral-shaped blades 4064 will provide a certain extrusion force to squeeze the silt into the conveying pipe 4067. As the silt accumulates, it is slowly squeezed upward and discharged from the position of the output pipe 4069 to the back side of the gate 401, thereby cleaning the bottom silt.

[0027] The surface of the delivery pipe 4067 is provided with a filter hole 4068, two blades 4064 are provided, and the two blades 4064 are symmetrically arranged, and an open groove 4066 is provided on the mud cover 4065. Through the provided filter hole 4068, because the blade 4064 is at the bottom of the water flow, the water flow is prevented from being discharged from the position of the output pipe 4069 together, so the filter hole 4068 is provided. After the water flow is transported into the interior of the delivery pipe 4067, the liquid will flow into the water flow again from the position of the filter hole 4068, and the silt impurities will be blocked by the filter hole 4068 and will be directly discharged from the tail of the output pipe 4069.

[0028] It also includes a pressure display component 5 for displaying the real-time water flow pressure value; The pressure display component 5 includes a display plate 501, which is fixed on the gate 401. A pointer 502 is arranged on the display plate 501. One end of the pointer 502 is fixedly connected to a rotating column 503 through a connecting rod. A spiral groove 504 is provided on the rotating column 503. A sliding rod 505 is slidably connected to the spiral groove 504. A connecting plate 507 is slidably connected to the bottom of the sliding rod 505. A sliding pressure plate 508 is rotatably connected to the bottom of the connecting plate 507. A central shaft 509 is slidably connected to the middle of the sliding pressure plate 508. The central shaft 509 is installed inside the rotating gate 402. The central shaft 509 is located at the sliding pressure plate 508. One side is connected with a damping spring 510. When water flows through the internal hole of the rotating gate 402, the water flow will drive the sliding pressure plate 508 to slide in the central axis 509, thereby squeezing the damping spring 510. The sliding pressure plate 508 will drive the sliding pressure plate 508 to move backward, thereby driving the sliding rod 505 to move horizontally. The sliding rod 505 slides in the spiral groove 504 on the rotating column 503, which will drive the rotating column 503 to rotate, and finally drive the pointer 502 to rotate on the display panel 501. The operator can judge the flow rate pressure value flowing through the rotating gate 402 at this time according to the pointer 502. It is convenient for the maintenance personnel or operators to control the gate at a later stage.

[0029] The display panel 501 is provided with a slide groove, and the sliding rod 505 is fixedly connected with a limiting rod 506, and the limiting rod 506 is slidably connected inside the slide groove. The rotating gate 402 is provided with a clearance groove 511, and the connecting plate 507 is located inside the clearance groove 511. The limiting rod 506 is set to slide in the slide groove, and the sliding rod 505 is restricted to always maintain lateral movement. In addition, the setting of the clearance groove 511 can prevent the connecting plate 507 from interfering with the rotating gate 402 when it rotates. In normal flow, the connecting plate 507 is in the clearance groove 511, and it will also block the water flow from the clearance groove 511. Working principle: first, after the water flows through the dam body 1, it will pass through the filter 2 and enter the area of ​​the gate 401. The filter 2 is mainly set to filter some weeds or floating objects to prevent the gate pump from being blocked by these debris. After that, the water will flow from the pump cover 4031, pass through the internal flow channel of the rotating gate 402, and be discharged to the tail of the gate 401. The water can also drive the pump blade 4032 to rotate during the flow process. If the water flow is turbid and the operator needs to divert the water flow in the upper area, he can directly rotate the wheel 404 and use the rotation and engagement of the worm 405 to drive the rotating gate 402 to rotate, and the rotating gate 402 will drive the pump body device 403 to change the angle, so as to direct the pump body device 403 to water areas of different depths, thereby diverting water flows of different water depths. At the same time, when the rotating gate 402 is rotated to the limit, the entire rotating gate 402 will drive the pump body device 403 upward, and the water outlet at the tail will rotate and block the inside of the gate 401. At this time, the water flow will be cut off, and the overall structure of a closed gate will be formed. And the pump body device 403 of the whole scheme is in a split plug-in design with the rotating gate 402. When the hand presses the large plate gear 4061, the internal rotating gear sleeve 4033 is meshed by the teeth and will be relatively fixed. At this time, rotating the pump cover 4031 will synchronously drive the internal pump blade 4032 to rotate together, and then drive the key 4034 behind the pump blade 4032 to rotate in the slot 4035, rotate to the opening of the slot 4035, and then pull it outward, and the whole pump body will be pulled out, thereby realizing separation, which is convenient for the later replacement and maintenance of the pump body. After the water flows through the pump body device 403, the internal water flow will drive the pump blade 4032 to rotate. Then, because the pump blade 4032 and the rotating gear sleeve 4033 are in a locked state, the rotating gear sleeve 4033 will be driven to rotate synchronously. After the meshing of the side teeth, the large plate gear 4061 will be slowly driven to rotate. Then, after the meshing between the gears, the shaft 4063 on the small gear 4062 will be driven to rotate, and the spirally structured blades 4064 on the shaft 4063 will move the silt at the bottom into the interior of the mud cover 4065. As the blades 4064 rotate, some silt will be squeezed and gradually enter the bottom of the delivery pipe 4067. As the spiral-shaped blades 4064 will provide a certain extrusion force, the silt is squeezed into the delivery pipe 4067. As the silt accumulates, it is slowly and gradually squeezed upward from the position of the output pipe 4069 to the rear side of the gate 401, so as to clean the bottom silt and reduce the accumulation of silt.The whole device is also provided with a pressure display component 5, which can display the real-time flow rate. Because when the water flows through the internal holes of the rotating gate 402, the water flow will drive the sliding pressure plate 508 to slide in the central axis 509, thereby squeezing the damping spring 510, and the sliding pressure plate 508 will drive the sliding pressure plate 508 to move backward, thereby driving the sliding rod 505 to move horizontally, and the sliding rod 505 slides in the spiral groove 504 on the rotating column 503, which will drive the rotating column 503 to rotate, and finally drive the pointer 502 to rotate on the display panel 501, and the operator can judge the flow rate pressure value flowing through the rotating gate 402 at this time according to the pointer 502, thereby judging how much the gate is opened and discharging the flow. If the angle of the rotating gate 402 is adjusted, the connecting plate 507 is in rotational connection with the sliding pressure plate 508, so the connecting plate 507 forms a certain angle with the sliding pressure plate 508, and the sliding of the sliding pressure plate 508 will also drive the connecting plate 507 to slide. When the connecting plate 507 slides, the sliding rod 505 will shrink in the connecting plate 507 during the lateral movement, which is convenient for giving way. At the same time, the setting of the limiting rod 506 will also limit the sliding rod 505 to always keep lateral movement. And the setting of the giving way groove 511 can prevent the connecting plate 507 from interfering with the rotating gate 402 when it rotates. In normal flow, the connecting plate 507 is in the giving way groove 511, which will also block the water flow from flowing out of the giving way groove 511.
