Description

Technical Field

[0001] This invention relates to the technical field of water conservancy engineering, and in particular to a sluice gate sand flushing structure and its dredging method for water conservancy engineering. Background Technology

[0002] In water conservancy projects, sluice gates are important facilities for regulating water flow, controlling water levels, and discharging sediment and floodwater. As a key component of sluice gates, the sediment flushing structure is mainly used to prevent sediment accumulation and ensure smooth water flow in the river channel and upstream of the gate. During long-term operation, sediment carried by the water flow tends to accumulate on the surface of the filter screen. If it is not cleaned in time, it will quickly cause the filter screen to become clogged, seriously affecting the flow capacity and sediment flushing effect. Traditional structures mostly rely on external power for cleaning, which has problems such as untimely cleaning, high maintenance costs, and dependence on external energy.

[0003] Water flow often contains hard particles such as pebbles. During the filtration process, some pebbles may become embedded in the gaps of the filter screen or get stuck in the transmission mechanism as the cleaning components move. This can cause the cleaning blades and other components to scrape the surface of the filter screen, or even damage the entire sludge removal mechanism, affecting the reliability and service life of the equipment. The sludge separated after filtration often contains large stones or compacted sludge. If discharged directly, it can easily block the sludge discharge channel and is not conducive to subsequent resource collection and utilization. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the current water conservancy project sluice gate sand flushing structure, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a sluice gate sand flushing structure for water conservancy projects, which aims to: flush sand and filter, provide elastic filtration and protection, remove stones by vibration, and disperse mud and sand.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sluice gate mechanism, comprising a gate inlet pipe, a gate pipe fixedly connected to the right side of the gate inlet pipe, a sluice gate disposed on the right side of the inner cavity of the gate pipe, a central control pipe fixedly connected to the right side of the gate pipe, a mud-leaking pipe fixedly connected to the right side of the central control pipe, a filter pipe fixedly connected to the right side of the mud-leaking pipe, and a water outlet fixedly connected to the right side of the filter pipe; characterized in that:

[0008] A sludge cleaning mechanism includes an annular ring disposed on the left side of the inner cavity of a filter tube. The surface of the annular ring is slidably connected to the inner wall of the filter tube. A filter screen is fixedly connected to the left side of the inner cavity of the filter tube and corresponding to the left side of the annular ring. A turntable is movably connected to the inner cavity of the filter screen via a rotating shaft. A circular disc is fixedly connected to the left side of the turntable. Six cleaning blades are fixedly connected to the surface of the circular disc and are evenly distributed. A synchronizing rod is fixedly connected to the right side of the turntable. The top and bottom of the synchronizing rod are fixedly connected to the top and bottom of the inner wall of the annular ring.

[0009] The drive mechanism is mounted on the central control tube. The drive mechanism can drive the sludge cleaning mechanism to perform cleaning work. It uses the flushing force of the water flow to drive the components to rotate, preventing mud and sand from depositing on the filter screen surface and causing the filter screen to become clogged.

[0010] The sweeping plate mechanism is set on the sweeping blade. The sweeping plate mechanism can assist the mud cleaning mechanism in cleaning mud and sand, and prevent the sweeping blade from directly scraping the surface of the filter screen. Once a stone gets stuck in the filter screen, it will jam the entire transmission component.

[0011] An anti-jamming mechanism is installed on the surface of the filter screen. The anti-jamming mechanism can further assist the cleaning plate mechanism by using a tapping method to loosen the stones stuck in the gaps of the filter screen, preventing the stones from embedding into the gaps of the filter screen and making them impossible to remove, thus preventing the filter screen from becoming clogged.

[0012] The dispersing mechanism is installed on the mud-leaking pipe. The dispersing mechanism enables the sluice gate mechanism to perform collection work by dispersing larger mud, sand and stones when the filter screen filters the mud and sand, making it easier to collect and recycle.

[0013] As a preferred embodiment of the sluice gate sand flushing structure of the water conservancy project described in this invention, the driving mechanism includes a blade, which is disposed at the top of the inner wall of the central control tube. The front end of the blade and the inner wall of the central control tube are movably connected by a rotating shaft. A blade rod is fixedly connected to the back end of the blade, and the back end of the blade rod is fixedly connected to the inner wall of the central control tube. A protrusion is fixedly connected to the top of the central control tube, and a metal rod is movably connected to the back end of the protrusion via a rotating shaft. The metal rod and the blade rod are connected by a transmission belt. A first gear is fixedly connected to the back end of the metal rod. A second gear is movably connected to the top of the central control tube via a rotating shaft. The front end of the second gear and the bottom of the first gear are meshed. A gear rod is fixedly connected to the top of the second gear. A rotating rod is movably connected to the inner cavity of the filter tube via a rotating shaft. The top of the rotating rod penetrates the top of the filter tube. The rotating rod and the gear rod are connected by a transmission belt. A synchronous gear is fixedly connected to the bottom of the rotating rod, penetrating the top of the inner wall of the filter tube. The left side of the synchronous gear and the right side of the annular ring are meshed.

[0014] As a preferred embodiment of the sluice gate sand flushing structure of the water conservancy project described in this invention, the cleaning plate mechanism includes a cleaning plate blade, which is disposed in the inner cavity of the cleaning plate blade. The surface of the cleaning plate blade and the inner cavity of the cleaning plate blade are movably connected. The left side of the cleaning plate blade extends through the left side of the cleaning plate blade. A spring assembly is fixedly connected to the left side of the cleaning plate blade. The left side of the spring assembly is fixedly connected to the left side of the inner wall of the cleaning plate blade. The right side of the cleaning plate blade contacts the left side of the filter screen.

[0015] As a preferred embodiment of the sluice gate sand flushing structure of the water conservancy project described in this invention, the anti-jamming mechanism includes a triangular plate, the right side of the triangular plate is fixedly connected to the back end of the left side of the filter screen, and the left inclined surface of the triangular plate is in contact with the right side of the cleaning blade.

[0016] As a preferred embodiment of the sluice gate sand flushing structure of the water conservancy project described in this invention, the dispersing mechanism includes a dispersing rod, the top of which is fixedly connected to the bottom of the filter pipe through the inner wall of the filter pipe, the left side of which is meshed with the bottom of the right side of the annular ring, the bottom of which is connected to the bottom of the filter pipe through the bottom of the filter pipe, the bottom of which is connected to the rotating column through a rotating shaft, the top of which is fixedly connected to a dispersing blade, and the rotating column and the dispersing rod are connected by a transmission belt.

[0017] As a preferred embodiment of the water conservancy project sluice gate sand flushing structure of the present invention, wherein: a protective shell is fixedly connected to the top of the central control pipe, and the right side of the bottom of the protective shell is fixedly connected to the top of the filter pipe.

[0018] As a preferred embodiment of the sluice gate sand flushing structure of the water conservancy project described in this invention, the right side of the annular ring is provided with a toothed groove, which meshes with the synchronous gear, the dispersing gear, and the annular ring.

[0019] As a preferred embodiment of the sluice gate sand flushing structure of the water conservancy project described in this invention, the bottom of the mud-leaking pipe is fixedly connected to a collection plate, the right side of the top of the collection plate is fixedly connected to the bottom of the filter pipe, and a collection groove is provided on the top of the collection plate at the position corresponding to the dispersing blade.

[0020] In view of the problems existing in the current method for dredging sluice gates in water conservancy projects, the present invention is proposed.

[0021] Therefore, the purpose of this invention is to provide a method for dredging sluice gates in water conservancy projects, which aims to: flush sand and filter, provide elastic filtration protection, remove stones by vibration, and disperse silt.

[0022] To solve the above-mentioned technical problems, the present invention provides the following technical solution: the water flow in the central control pipe drives the blades to rotate, and the water energy is used to drive the removal of mud and sand deposited on the surface of the filter screen. The cleaning blades make elastic contact with the filter screen with the help of the spring assembly, generating a knocking effect, which loosens and discharges the stones stuck in the gaps of the filter screen. The breaking blades rotate at the bottom of the mud-leaking pipe, breaking up and crushing large pieces of mud, sand and stones that fall into the mud-leaking pipe after being filtered by the filter screen.

[0023] As a preferred embodiment of the sluice gate dredging method for water conservancy projects described in this invention, the method includes: a drive mechanism that utilizes the flushing force of water flow within a central control pipe to rotate the paddles, causing the sweeping blades and sweeping plates to continuously clean the filter screen surface. This self-driven water-powered process removes sediment deposited on the filter screen surface, preventing filter screen blockage due to sediment accumulation and ensuring the long-term stable operation of the sluice gate's dredging structure. Furthermore, by incorporating a sweeping plate mechanism and an anti-jamming mechanism, the sweeping plates elastically contact the filter screen via springs, preventing the sweeping blades from directly and rigidly scraping the filter screen surface. The triangular plate in the anti-jamming mechanism generates a knocking effect when the cleaning blades move, loosening and discharging stones stuck in the gaps of the filter screen. This prevents stones from embedding in the filter screen and causing the sludge cleaning mechanism to jam, thus protecting the service life of the filter screen and transmission components. By setting up a dispersing mechanism, the rotation of the ring drives the dispersing gear to rotate, which in turn drives the dispersing blades to rotate at the bottom of the sludge discharge pipe. This breaks up large pieces of mud, sand, and stones that fall into the sludge discharge pipe after being filtered by the filter screen. These are then collected centrally through the collection plate and collection trough, facilitating subsequent resource utilization and preventing large deposits from clogging the sludge discharge channel.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention sets up a drive mechanism and a sludge cleaning mechanism. The water flow in the central control pipe drives the blades to rotate. The gear transmission system drives the ring and turntable to rotate synchronously, so that the cleaning blades and cleaning plates continuously clean the filter screen surface. This achieves water-powered self-driven sludge cleaning without the need for an external power source. It effectively prevents mud and sand from depositing on the filter screen surface and causing blockage, and ensures the long-term stable operation of the sluice gate's sand flushing structure.

[0026] 2. By setting up a cleaning plate mechanism, the present invention provides an elastically telescopic cleaning plate on the cleaning blade. With the help of a spring assembly, the cleaning plate and the filter screen are always kept in elastic contact, which avoids the cleaning blade directly scraping the surface of the filter screen. This further reduces the rigid friction loss between the cleaning components and the filter screen and extends the service life of the filter screen and the cleaning components.

[0027] 3. This invention, by setting an anti-jamming mechanism, fixes a triangular plate on the surface of the filter screen. The left inclined surface of the triangular plate and the right side of the cleaning blade generate a periodic knocking effect during the movement, causing the stones stuck in the gaps of the filter screen to be vibrated and loosened and discharged. This further improves the anti-jamming function in the sludge cleaning process and effectively prevents stones from embedding in the filter screen and causing the sludge cleaning mechanism to jam or be damaged.

[0028] 4. This invention, by setting up a dispersing mechanism, utilizes the rotation of the annular ring to simultaneously drive the dispersing gear to rotate, and drives the dispersing blades to rotate at the bottom of the sludge-leaking pipe via a transmission belt. This disperses and breaks up large pieces of mud, sand, and stones that fall into the sludge-leaking pipe after being filtered by the filter screen, and collects them centrally through a collection plate and collection trough. This further improves the function of fine treatment and resource recycling of mud and sand, avoids large silt deposits clogging the sludge discharge channel, and realizes the effective reuse of filtered waste.

[0044] Example 1

[0045] The sluice gate mechanism 100 includes a gate inlet pipe 101, a gate pipe 102 fixedly connected to the right side of the gate inlet pipe 101, a sluice gate 103 provided on the right side of the inner cavity of the gate pipe 102, a central control pipe 104 fixedly connected to the right side of the gate pipe 102, a mud leakage pipe 105 fixedly connected to the right side of the central control pipe 104, a filter pipe 106 fixedly connected to the right side of the mud leakage pipe 105, and a water outlet 107 fixedly connected to the right side of the filter pipe 106.

[0046] One embodiment of this example is as follows: a sludge cleaning mechanism 200, which includes an annular ring 201. The annular ring 201 is disposed on the left side of the inner cavity of the filter tube 106. The surface of the annular ring 201 is slidably connected to the inner wall of the filter tube 106. A filter screen 202 is fixedly connected to the left side of the inner cavity of the filter tube 106 and corresponding to the left side of the annular ring 201. A turntable 203 is movably connected to the inner cavity of the filter screen 202 through a rotating shaft. A circular disk 204 is fixedly connected to the left side of the turntable 203. A cleaning blade 205 is fixedly connected to the surface of the circular disk 204. Six cleaning blades 205 are provided and are evenly distributed. A synchronizing rod 206 is fixedly connected to the right side of the turntable 203. The top and bottom of the synchronizing rod 206 are fixedly connected to the top and bottom of the inner wall of the annular ring 201.

[0047] By setting up a sludge removal mechanism 200, the water flow can drive the cleaning blade 205 to rotate the circular disk 204 and the turntable 203. The turntable 203 drives the annular ring 201 to slide on the inner wall of the filter pipe 106 through the synchronizing rod 206, thereby scraping off the sludge accumulated on the surface of the filter screen 202 and pushing it to the sludge leakage pipe 105 for discharge. This solves the problem that the filter screen 202 in the sluice gate structure is easily blocked by sludge, which affects the drainage efficiency and requires frequent manual cleaning.

[0048] A protective shell 104a is fixedly connected to the top of the central control tube 104, and the bottom right side of the protective shell 104a is fixedly connected to the top of the filter tube 106.

[0049] By setting up a protective shell 104a, the transmission components exposed outside the central control tube 104 and filter tube 106 in the drive mechanism 300 can be sealed and protected to prevent foreign matter from entering, ensure the stable operation of the transmission system, and solve the problem that external environmental factors can easily cause damage or jamming of transmission components and affect the normal operation of the mud cleaning mechanism 200.

[0050] The right side of the annular ring 201 is provided with a toothed groove 201a, which meshes with the synchronous gear 309, the dispersing gear 602, and the annular ring 201.

[0051] By setting the tooth groove 201a, the synchronous gear 309 and the dispersing gear 602 can simultaneously form a stable meshing transmission with the ring 201, accurately transmitting the power of the drive mechanism 300 to the mud cleaning mechanism 200 and the dispersing mechanism 600, realizing the dual functions of synchronous driving of a single ring 201 for cleaning and dispersing, and solving the problems of unstable power transmission and poor coordination of multiple mechanisms.

[0052] Example 2

[0053] Based on Embodiment 1, this embodiment considers that simply relying on the direct water flow to clean the cleaning blades 205 cannot provide a continuous and stable rotational power for the sludge removal mechanism 200, and that the annular ring 201 is prone to jamming or asynchronous movement due to uneven resistance when sliding on the inner wall of the filter tube 106, resulting in incomplete sludge removal and uneven removal of sludge from the surface of the filter screen 202. Therefore, this embodiment provides a drive mechanism 300, which includes a paddle 301. The paddle 301 is located at the top of the inner wall of the central control tube 104. The front end of the paddle 301 is movably connected to the inner wall of the central control tube 104 via a rotating shaft. A paddle rod 302 is fixedly connected to the back end of the paddle 301, and the back end of the paddle rod 302 is fixedly connected to the inner wall of the central control tube 104. A protrusion 303 is fixedly connected to the top of the central control tube 104. The back end of the lifting block 303 is movably connected to a metal rod 304 via a rotating shaft. The metal rod 304 and the paddle rod 302 are connected via a transmission belt. The back end of the metal rod 304 is fixedly connected to a first gear 305. The top of the central control tube 104 is movably connected to a second gear 306 via a rotating shaft. The front end of the second gear 306 is meshed with the bottom of the first gear 305. The top of the second gear 306 is fixedly connected to a gear rod 307. The inner cavity of the filter tube 106 is movably connected to a rotating rod 308 via a rotating shaft. The top of the rotating rod 308 penetrates the top of the filter tube 106. The rotating rod 308 and the gear rod 307 are connected via a transmission belt. The bottom of the rotating rod 308 penetrates the inner wall of the filter tube 106 and the top is fixedly connected to a synchronous gear 309. The left side of the synchronous gear 309 is meshed with the right side of the annular ring 201.

[0054] By setting up a drive mechanism 300, the scouring force of the water flow in the central control pipe 104 can be used to drive the blade 301 to rotate. The power is transmitted to the synchronous gear 309 through the paddle rod 302, transmission belt, metal rod 304, first gear 305, second gear 306, gear rod 307, and rotating rod 308 in sequence. The synchronous gear 309 meshes with the tooth groove 201a of the ring 201 to provide stable and continuous rotational power to the sludge cleaning mechanism 200. This achieves the effect of self-driving by water energy and automatically completing the sludge cleaning operation on the surface of the filter screen 202 without external energy. This solves the problem of insufficient driving force and incomplete sludge cleaning caused by relying on external power or simply relying on direct water flow in traditional structures.

[0055] Example 3

[0056] Based on Embodiment 2, this embodiment considers that the driving mechanism 300 in Embodiment 2 can provide stable rotational power to the annular ring 201 to drive the cleaning blades 205 to clean the surface of the filter screen 202. However, the cleaning blades 205 still have direct rigid contact with the filter screen 202, which can easily cause wear and damage to the filter screen 202 over long-term operation. Furthermore, when hard objects such as stones get stuck in the gaps of the filter screen 202, the cleaning blades 205 cannot adaptively avoid them, which can easily lead to jamming or even damage to the transmission components. Therefore, this embodiment... In this embodiment, a cleaning plate mechanism 400 is provided, which includes a cleaning plate blade 401. The cleaning plate blade 401 is disposed in the inner cavity of the cleaning blade 205. The surface of the cleaning plate blade 401 is movably connected to the inner cavity of the cleaning blade 205. The left side of the cleaning plate blade 401 penetrates the left side of the cleaning blade 205. A spring assembly 402 is fixedly connected to the left side of the cleaning plate blade 401. The left side of the spring assembly 402 is fixedly connected to the left side of the inner wall of the cleaning blade 205. The right side of the cleaning plate blade 401 contacts the left side of the filter screen 202.

[0057] By setting up a cleaning plate mechanism 400, the cleaning plate blade 401 is elastically connected to the cleaning blade 205 through the spring assembly 402. When rotating with the cleaning blade 205, it always maintains elastic contact with the surface of the filter screen 202. This achieves the function of effectively scraping off the silt attached to the surface of the filter screen 202, and automatically compressing and avoiding hard objects such as stones when encountering them, thus avoiding rigid scraping damage to the filter screen 202 or jamming of the transmission components.

[0058] Example 4

[0059] Based on Embodiment 3, this embodiment considers that the cleaning plate mechanism 400 in Embodiment 3 can achieve elastic contact between the cleaning plate blade 401 and the filter screen 202, avoiding rigid scraping damage, and automatically avoids stones. However, when stones or other hard objects are partially stuck in the mesh gaps of the filter screen 202, elastic scraping alone cannot effectively push them out. The stones may continue to be embedded in the gaps of the filter screen 202, causing local blockage to worsen. In fact, with the repeated movement of the cleaning plate blade 401, the stones are pushed tighter and tighter, causing permanent blockage of the filter screen 202 or obstruction of the movement of the cleaning plate blade 401. Therefore, this embodiment provides an anti-jamming mechanism 500. The anti-jamming mechanism 500 includes a triangular plate 501. The right side of the triangular plate 501 is fixedly connected to the back end of the left side of the filter screen 202, and the left inclined surface of the triangular plate 501 contacts the right side of the cleaning plate blade 401.

[0060] By setting up an anti-jamming mechanism 500, the left inclined surface of the triangular plate 501 and the right side of the sweeping blade 401 generate periodic compression during relative movement. Under the action of the spring assembly 402, the sweeping blade 401 generates radial displacement along the inclined surface and forms an instantaneous rebound impact. This achieves the function of continuously applying intermittent vibration impact to the surface of the filter screen 202 during the cleaning process, forcing the stones stuck in the gaps of the filter screen 202 to loosen and fall out, preventing the stones from being embedded for a long time and causing the filter screen 202 to become clogged or the transmission components to jam. At the same time, the guiding effect of the inclined surface helps the sweeping blade 401 to smoothly cross obstacles.

[0061] Example 5

[0062] Based on Embodiment 1, this embodiment considers that the sludge removal mechanism 200 in Embodiment 1 can use water flow to drive the sweeping blades 205 to rotate, scraping off the sludge accumulated on the surface of the filter screen 202 and pushing it to the sludge discharge pipe 105 for discharge, effectively preventing filter screen blockage. However, there are still large particles of mud, sand and stones mixed in with the scraped sludge. These large materials are prone to depositing and caking inside the pipe after entering the sludge discharge pipe 105, and may even block the sludge discharge pipe 105 and subsequent sludge discharge channels, resulting in unsmooth sludge removal and discharge, and large sludge deposits are difficult to directly recover and utilize. To address the issue of dispersing, this embodiment includes a dispersing mechanism 600. The dispersing mechanism 600 includes a dispersing rod 601. The top of the dispersing rod 601 is fixedly connected to the bottom of the inner wall of the filter tube 106. The left side of the dispersing gear 602 is meshed with the bottom of the right side of the annular ring 201. The bottom of the dispersing rod 601 is connected to the bottom of the filter tube 106. The bottom of the mud-leaking pipe 105 is movably connected to a rotating column 603 via a rotating shaft. The top of the rotating column 603 is fixedly connected to a dispersing blade 604. The rotating column 603 and the dispersing rod 601 are connected by a transmission belt.

[0063] By setting up the dispersing mechanism 600, the dispersing rod 601, the transmission belt-driven rotating column 603, and the dispersing blades 604 can continuously rotate and break at the bottom of the mud-leaking pipe 105, thereby breaking large pieces of mud, sand, and stones that fall into the mud-leaking pipe 105 into fine particles, avoiding large silt from blocking the mud discharge channel, and facilitating subsequent centralized collection and resource utilization.

[0064] A collection plate 105a is fixedly connected to the bottom of the mud-leaking pipe 105. The right side of the top of the collection plate 105a is fixedly connected to the bottom of the filter pipe 106. A collection groove 105b is provided on the top of the collection plate 105a and at the position corresponding to the dispersing blade 604.

[0065] By setting up a collection plate 105a and a collection trough 105b, the small particles of mud and sand after being crushed by the dispersing blade 604 are received, guided and collected in a centralized manner, preventing the crushed mud and sand from scattering everywhere and causing secondary siltation or pollution. This facilitates regular cleaning and resource recycling, while also preventing mud and sand from accumulating at the bottom of the mud leakage pipe 105 and affecting the normal operation of the dispersing blade 604.

[0066] In summary, water flows through the gate inlet pipe 101 into the gate pipe 102, and after being regulated by the sluice gate 103, it flows into the central control pipe 104. The scouring force of the water flow in the central control pipe 104 acts on the blade 301, driving the blade 301 to rotate around the shaft. The blade 301 drives the blade rod 302 to rotate synchronously. The blade rod 302 drives the metal rod 304 to rotate through the transmission belt. The metal rod 304 drives the first gear 305 to rotate. The first gear 305 meshes with the second gear 306, causing the second gear 306 and the gear rod 307 to rotate. The gear rod 307 drives the rotating rod 308 to rotate through the transmission belt. The rotating rod 308 drives the synchronous gear 309 to rotate. The synchronous gear 309 meshes with the tooth groove 201a on the right side of the annular ring 201, causing the annular ring 201 to slide on the inner wall of the filter pipe 106.

[0067] The annular ring 201 drives the turntable 203 and the circular disk 204 to rotate via the synchronous rod 206. The six cleaning blades 205 on the circular disk 204 rotate accordingly. The cleaning blades 205 drive the cleaning plate blades 401 to continuously clean the surface of the filter screen 202, scraping off the sludge deposited on the surface of the filter screen 202 and pushing it to the sludge leakage pipe 105. The cleaning plate blades 401 are elastically connected to the cleaning blades 205 via the spring assembly 402, always maintaining elastic contact with the left side of the filter screen 202 to avoid rigid scraping damage to the filter screen 202. When the cleaning plate blades 401 move to the position of the triangular plate 501, the right side of the cleaning plate blades 401 contacts the left inclined surface of the triangular plate 501, generating periodic squeezing and releasing, forming an instantaneous rebound and knocking effect, which loosens and falls off the stones stuck in the gaps of the filter screen 202, preventing the transmission components from jamming.

[0068] When the annular ring 201 rotates, the toothed groove 201a on its right side synchronously drives the dispersing gear 602 to rotate. The dispersing gear 602 drives the dispersing rod 601 to rotate. The dispersing rod 601 drives the rotating column 603 and the dispersing blades 604 to rotate continuously at the bottom of the mud-leaking pipe 105 through the transmission belt. Large pieces of mud, sand and stones scraped from the filter screen 202 and falling into the mud-leaking pipe 105 are broken into fine particles by the dispersing blades 604. The broken mud and sand particles fall into the collection trough 105b at the top of the collection plate 105a for centralized collection, which facilitates subsequent regular cleaning and resource recycling.

10. A method for dredging sluice gates in a water conservancy project according to claim 9, characterized in that: include, By setting up a drive mechanism (300), the water flow in the central control pipe (104) drives the blades (301) to rotate, so that the cleaning blades (205) and cleaning plate blades (401) continuously clean the surface of the filter screen (202).
