Abstract
Description
Technical Field
[0001] This invention relates to the field of gate pump dredging technology, specifically a separate gate pump dredging mechanism. Background Technology
[0002] During the construction of water conservancy projects, gates and pumps are usually installed on the river. The gates mainly serve to block the river water, while the pumps are mainly used to pump water from one side of the gate to the other. The combined use of the two plays an important role in the management of the water environment, the construction of water conservancy ecology, and flood control and drainage in the region.
[0003] Currently, in the operation of gate pumps, the pump body is directly installed on the gate, making it impossible to effectively control the gate pump. For example, when the gate pump needs to be closed, both pump bodies are still in a dredging state, and water can still flow out through the gate pump. Therefore, the existing integrated gate pump is quite limited in use. At the same time, after long-term use, silt will accumulate on one side of the gate at the water inlet of the gate pump. Over time, the accumulation will put great pressure on the gate and may even damage it. Therefore, a separate gate pump dredging mechanism is proposed to solve the above-mentioned problems.

[0018] (III) Beneficial Effects
[0019] Compared with the prior art, the present invention provides a separate gate pump dredging mechanism, which has the following beneficial effects:
[0020] 1. This separate gate pump dredging mechanism, through the specially designed gate, can first control the pump body to change its depth to divert water flow at different depths. At the same time, it can also control the rotation of the pump body to make it rotate upwards, thereby directly closing the gate and transforming it into a traditional gate structure. This improves the versatility of the gate's use and allows it to be applied to divert water with different flow characteristics.
[0021] 2. This separate gate pump sludge removal mechanism, through the set cleaning mechanism, can use the power of the pump blade rotation to drive the cleaning mechanism to spirally squeeze the sludge deposited at the bottom, and squeeze it upward from the position of the conveying pipe, so that it can be directly separated from one side of the gate and directly conveyed to the other side of the gate through spiral squeezing. This avoids excessive sludge accumulation, which would cause the gate to be under great stress, and the situation where sludge adheres to the gate for a long time.
[0022] 3. This separate gate pump sludge removal mechanism, through the pressure display device, allows for real-time observation of water flow velocity and pressure via a dial display during water diversion. This facilitates operator control of the gate, determining whether to raise it or to what height for discharge, thus preventing excessive water pressure from causing pressure damage to the gate.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figures 1-7 A separate gate pump dredging mechanism includes a dam body 1, on which a hydraulic cylinder 3 is installed. The output end of the hydraulic cylinder 3 is connected to a gate pump assembly 4. A filter screen 2 is installed on the dam body 1. The filter screen 2 is inclined, and its main purpose is to filter weeds or floating objects to prevent the gate pump from being blocked by these debris. The inclined design also facilitates cleaning by operators later.
[0033] The gate pump assembly 4 includes a gate mechanism, a pump body device 403, a pump adjusting 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 via a connector. A rotary gate 402 is connected to the middle of the gate 401 via a shaft. The pump body device 403 is mounted on the rotary gate 402, and the pump adjusting device is connected to the rotary gate 402 to adjust the orientation angle of the pump body device 403. This separate gate pump sludge removal mechanism, through the specially structured gate, can first control the pump body to change its depth to divert water flow at different depths. Simultaneously, it can control the rotation of the pump body, causing it to rotate upwards, thereby directly closing the gate 401 and transforming it into a traditional gate 401 structure. This improves the versatility of the gate 401's application to divert water with different flow characteristics.
[0034] The pump regulating device includes a worm gear 405, which is rotatably connected to a gate 401. One end of the worm gear 405 is fixedly connected to a rotating wheel 404. The rotating gate 402 is provided with threads, and the worm gear 405 meshes with the threads on the rotating gate 402. Directly rotating the rotating wheel 404, the rotation of the worm gear 405 drives the rotating gate 402 to rotate. The rotating gate 402 then drives the pump body device 403 to change angles, thus orienting the pump body device 403 towards waters of different depths, thereby diverting water flows of different depths. When the rotating gate 402 rotates to its limit, the entire rotating gate 402 will drive the pump body device 403 upwards, and the outlet at the tail will rotate and block the inside of the gate 401, at which point the water flow will be stopped. The whole device forms the structure of a traditional closed gate, achieving complete closure.
[0035] The pump body assembly 403 includes a pump cover 4031, inside which a pump impeller 4032 is disposed. The pump cover 4031 is rotatably connected to the inside of a rotary gate 402. One end of the pump impeller 4032 is fixedly connected to a locking key 4034, which engages with the rotary gate 402. By rotating the pump cover 4031, the pump impeller 4032 inside will rotate synchronously, thereby causing the locking key 4034 behind the pump impeller 4032 to rotate within a slot 4035. When the key rotates to the opening of the slot 4035, it can be pulled outwards, thus separating the pump body for easy replacement and maintenance in the future.
[0036] The rotary gate 402 is internally connected to a rotating gear sleeve 4033. The rotating gear sleeve 4033 has a slot 4035, and a key 4034 engages inside 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 engaged, the pump blade 4032 will synchronously drive the rotating gear sleeve 4033 to rotate. Through the meshing of the side teeth, the pump blade 4033 will slowly drive the rotation of the large disc gear 4061. The flow of water is used as the power source to drive the autonomous movement of the cleaning mechanism 406, thereby saving energy.
[0037] 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 meshes below the large disc gear 4061. 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 covers 4065 are fixedly connected to the gate 401. A spiral blade 4064 is fixedly connected to the shaft 4063. A conveying pipe 4067 is connected to the mud cover 4065. An output pipe 4069 is connected to the top of the conveying pipe 4067. The rotation of the large disc gear 4061, through the meshing of the gears, will drive the shaft 4063 on the small gear 4062 to rotate. The spiral blades 4064 on the shaft 4063 will push the sludge at the bottom into the interior of the mud cover 4065. As the blades 4064 rotate, some sludge will be squeezed and gradually pushed into the bottom of the conveying pipe 4067. The spiral blades 4064 will provide a certain squeezing force, squeezing the sludge into the conveying pipe 4067. As the sludge accumulates, it will be slowly squeezed upwards and discharged from the output pipe 4069 to the rear of the gate 401, thus cleaning the sludge at the bottom.
[0038] The surface of the delivery pipe 4067 is provided with filter holes 4068, and two blades 4064 are provided, which are arranged symmetrically. The mud cover 4065 is provided with an opening groove 4066. Because the blades 4064 are located at the bottom of the water flow, the filter holes 4068 are provided to prevent the water from being discharged from the outlet pipe 4069. After the water flow enters the interior of the delivery pipe 4067, the liquid will flow back into the water flow through the filter holes 4068, while the sludge and impurities will be blocked by the filter holes 4068 and discharged directly from the tail of the outlet pipe 4069.
[0039] It also includes a pressure display component 5, used to display real-time water flow pressure values;
[0040] The pressure display assembly 5 includes a display panel 501, which is fixed to the gate 401. A pointer 502 is mounted on the display panel 501. One end of the pointer 502 is fixedly connected to a rotating column 503 via a connecting rod. A spiral groove 504 is formed on the rotating column 503, and 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, and 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 rotary gate 402 and is located within the sliding pressure plate 508. A damping spring 510 is connected to one side. When water flows through the internal holes of the rotary gate 402, the water flow will drive the sliding pressure plate 508 to slide within the central shaft 509, thereby compressing the damping spring 510. The sliding pressure plate 508 will then move backward, causing the sliding rod 505 to move laterally. The sliding rod 505 slides within the spiral groove 504 on the rotating column 503, causing the rotating column 503 to rotate. Ultimately, this causes the pointer 502 to rotate on the display panel 501, allowing the operator to determine the flow velocity and pressure value passing through the rotary gate 402 based on the pointer 502. This facilitates the control of the gate by maintenance personnel or operators.
[0041] A sliding groove is provided on the display panel 501, and a limiting rod 506 is fixedly connected to the sliding rod 505. The limiting rod 506 is slidably connected inside the sliding groove. A clearance groove 511 is provided on the rotary gate 402, and a connecting plate 507 is located inside the clearance groove 511. By allowing the limiting rod 506 to slide within the sliding groove, the sliding rod 505 is restricted to maintain lateral movement. Furthermore, the clearance groove 511 ensures that the connecting plate 507 will not interfere with the rotary gate 402 when it rotates. During normal flow, the connecting plate 507, positioned within the clearance groove 511, also prevents water from flowing out of the clearance groove 511.
[0042] Working principle: First, after the water flows through the dam body 1, it will pass through the filter screen 2 and enter the area of the gate 401. The filter screen 2 is mainly set to filter some weeds or floating objects to prevent the gate pump from being blocked by these objects. Then, the water will flow from the pump cover 4031 into the internal flow channel of the rotary gate 402 and be discharged to the tail of the gate 401. In addition, the water flow can also drive the pump blades 4032 to rotate during the flow. If the water flow is turbid and the operator needs to divert the water flow from the upper area, they can directly rotate the wheel 404. The rotation of the worm gear 405 will drive the rotary gate 402 to rotate, which will in turn drive the pump body device 403 to change its angle, thus orienting the pump body device 403 towards waters of different depths and diverting water flow at different depths. When the rotary gate 402 rotates to its limit, the entire rotary gate 402 will drive the pump body device 403 upward, and the outlet at the tail will rotate and block the inside of the gate 401, thus stopping the water flow and forming a closed gate structure. Furthermore, the pump body device 403 of the entire scheme is designed as a separate plug-in unit with the rotary gate 402. When the large disc gear 4061 is pressed by hand, the internal rotating gear sleeve 4033 is engaged 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, thereby driving the retaining key 4034 behind the pump blade 4032 to rotate in the retaining groove 4035. When it rotates to the opening of the retaining groove 4035, it is pulled outward, and the entire pump body will be pulled out, thus achieving separation, which facilitates the replacement and maintenance of the pump body in the future. After the water flows through the pump body 403, the internal water flow will drive the pump blades 4032 to rotate. Then, because the pump blades 4032 and the rotating gear sleeve 4033 are in a snap-fit state, the rotating gear sleeve 4033 will rotate synchronously. Through the meshing of the side teeth, the large disc gear 4061 will be slowly driven to rotate. Then, through the meshing between the gears, the shaft 4063 on the small gear 4062 will be driven to rotate. The spiral blades 4064 on the shaft 4063 will push the sludge at the bottom into the interior of the mud cover 4065. As the blades 4064 rotate, some sludge will be squeezed and gradually enter the bottom of the conveying pipe 4067. The spiral blades 4064 will provide a certain squeezing force, squeezing the sludge into the conveying pipe 4067. As the sludge accumulates, it will be slowly squeezed upward and discharged from the output pipe 4069 to the rear of the gate 401, thus cleaning the sludge at the bottom and reducing the accumulation of sludge.The entire device is also equipped with a pressure display component 5, which can display the real-time flow rate. When the water flows through the internal holes of the rotary gate 402, it will drive the sliding pressure plate 508 to slide within the central shaft 509, thereby compressing the damping spring 510. The sliding pressure plate 508 will then move backward, thereby driving the sliding rod 505 to move laterally. The sliding rod 505 slides within the spiral groove 504 on the rotating column 503, which will drive the rotating column 503 to rotate. Finally, the pointer 502 will rotate on the display panel 501. The operator can then judge the flow rate and pressure value flowing through the rotary gate 402 based on the pointer 502, thereby determining how much the gate should be opened and releasing the flow. If the rotary gate 402 is adjusted, the connecting plate 507 is now rotatably connected to the sliding pressure plate 508. Therefore, the connecting plate 507 and the sliding pressure plate 508 will form a certain angle. The sliding of the sliding pressure plate 508 will also cause the connecting plate 507 to slide. During the sliding of the connecting plate 507, the sliding rod 505 will retract within the connecting plate 507 to facilitate movement. Simultaneously, the limiting rod 506 will restrict the sliding rod 505 from maintaining lateral movement. Furthermore, the clearance groove 511 ensures that the connecting plate 507 will not interfere with the rotary gate 402 when it rotates. During normal flow, the connecting plate 507, positioned within the clearance groove 511, will also prevent water from flowing out of the clearance groove 511.
