Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a lifting type water conservancy gate for water conservancy projects. Background Art

[0002] The existing lifting hydraulic gates used in water conservancy projects can effectively control the water level and regulate the flow in the process of intercepting the water flow, but they are insufficient in dealing with garbage in the water. The gates will intercept the floating garbage in the water in the process of intercepting the water flow. When the gates intercept the garbage in the water, in order to prevent the garbage from flowing into the farmland or downstream, it is usually necessary to manually remove the garbage when the gates are opened. The garbage removed manually is mainly floating objects on the water surface, and there is still garbage under the water and it cannot be effectively cleaned up. The cleaning of underwater garbage is relatively difficult, resulting in an increase in the accumulation of garbage near the gates, which increases the pressure on the gates and affects the service life of the gates. Summary of the invention

[0003] Based on this, it is necessary to provide a lifting type hydraulic gate for water conservancy projects in view of the problems existing in the garbage cleaning near the current hydraulic gates.

[0004] The above purpose is achieved through the following technical solutions:

[0012] A cleaning bucket is connected to a side of the second sliding block away from the connecting rod and has an opening. When the active elliptical gear rotates to drive the driven elliptical gear to rotate, the second sliding block moves vertically along the sliding groove, so that the cleaning bucket moves up and down driven by the second sliding block, and moves from the downstream side of the gate to the upstream side of the gate, so that debris in the upstream liquid enters the cleaning bucket through the opening.

[0013] Furthermore, the lock chamber comprises:

[0014] An upstream connecting section, one side of which is higher than the upstream liquid level, and an upstream flow channel is provided in the upstream connecting section;

[0015] A downstream connecting section has one side connected to the other side of the upstream connecting section and arranged in a step, and the other side is higher than the downstream liquid level. A downstream flow channel connected to the upstream flow channel is provided in the downstream connecting section, and the gate is provided in the upstream flow channel.

[0016] Furthermore, the lifting type hydraulic gate for water conservancy projects also includes:

[0017] A base, which is embedded in the lock chamber, and a lifting slot is provided on the base;

[0018] A lifting cylinder is arranged in the lifting slot, and a power output end of the lifting cylinder is connected to the adjusting bracket. When driven by the lifting cylinder, the adjusting bracket moves along the lifting slot to open and close the gate.

[0019] Furthermore, the lifting type hydraulic gate for water conservancy projects also includes:

[0020] An auxiliary frame, one end of which is connected to the lower part of the adjusting bracket and is located on the upper side of the lifting slot, and the other end of which extends in a direction away from the lifting slot to the center position of the adjusting bracket;

[0021] A motor is arranged on the auxiliary frame and connected to the active elliptical gear. The arrangement position of the motor corresponds to the center position of the adjustment bracket. The motor is used to drive the active elliptical gear to rotate.

[0022] Furthermore, the auxiliary frame includes:

[0023] A first C-shaped frame, the center of the closed end of which is connected to the adjustment bracket;

[0024] The second C-shaped frame has an open end connected to the open end of the first C-shaped frame, the second C-shaped frame is perpendicular to the first C-shaped frame, and a motor is installed at the center of the closed end of the second C-shaped frame.

[0025] Furthermore, grooves are respectively provided on opposite sides of the gate chamber, the base, the lifting slot and the auxiliary frame are installed in the grooves, and the grooves are independent of the upstream flow channel.

[0026] Further, the cleaning bucket includes:

[0027] A barrel body, one side of which is provided with an opening, and the barrel body is provided with a connecting shaft;

[0028] A plurality of cleaning blades are evenly arranged on the outer wall of the connecting shaft;

[0029] A power source is arranged in the barrel body and connected to the connecting shaft. The power source is used to drive the cleaning blades to rotate so as to introduce the debris in the upstream liquid into the barrel body through the opening.

[0030] Further, the cleaning bucket includes:

[0031] The barrel body has an opening on one side, a filter hole is provided on the outer peripheral wall of the barrel body to allow the upstream liquid to enter the barrel body, and a connecting shaft is provided in the barrel body;

[0032] A plurality of cleaning blades are evenly arranged on the outer wall of the connecting shaft. The cleaning blades rotate under the impact of the upstream liquid to introduce the debris in the upstream liquid into the barrel body through the opening.

[0033] Further, the cleaning blade comprises:

[0034] A straight plate, one end of which is connected to the connecting shaft, and a filter hole is provided on the straight plate;

[0035] A curved plate, one end of which is connected to the other end of the straight plate, and the other end of which is bent toward the downstream direction. A filter hole is provided on the curved plate so that when the upstream liquid impacts the cleaning blade to drive it to rotate, part of the impact force of the upstream liquid on the cleaning blade is removed.

[0036] Furthermore, the adjustment bracket is a cross-shaped structure, and the sliding groove is a cross through groove.

[0037] The beneficial effects of the present invention are:

[0038] The present invention provides an adjustment bracket and a connecting rod and a sliding block that move along the adjustment bracket, so that the gate and the cleaning bucket can be staggered and do not interfere with each other when working together. When the gate moves back and forth from upstream to downstream, the cleaning bucket can move up and down accordingly, which can not only clean floating objects on the water surface, but also clean the garbage on the bottom of the water, thereby improving the comprehensiveness of cleaning. In addition, when cleaning the garbage on the bottom of the water, the amount of sediment accumulated near the upstream gate can also be reduced, effectively reducing the pressure on the gate and extending the service life of the gate.

[0039] The linkage mechanism of the present invention is driven by the special-shaped gears used in conjunction. The special-shaped gears can enable the cleaning bucket to run at a slower speed during the water inlet and outlet processes, which helps to better collect garbage and improve the environmental protection effect and work efficiency of the water conservancy project.

[0055] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0056] The embodiment of the present invention provides a lifting type hydraulic gate for hydraulic engineering, such as Figure 1-Figure 5 As shown, it includes a lock chamber 100 , a lock gate 200 , an adjustment bracket 300 , a connecting rod 305 , a driving elliptical gear 3041 , a driven elliptical gear 3042 and a cleaning bucket 400 .

[0057] The gate 200 is disposed in the gate chamber 100, and is used to seal the gate chamber 100. The adjustment bracket 300 is disposed on opposite sides of the gate chamber 100, and can move along the vertical direction of the gate chamber 100. The adjustment bracket 300 is provided with a sliding groove 306, wherein the adjustment bracket 300 is a cross-shaped structure, and the sliding groove 306 is a cross-through groove, so that the sliding groove 306 provides a sliding path in multiple directions.

[0058] When the adjusting bracket 300 moves upward along the vertical direction of the gate chamber 100, the gate 200 is opened. Otherwise, the gate 200 is closed. By providing a movable adjusting bracket 300, the lifting and lowering of the gate 200 can be accurately controlled to achieve the sealing performance of the gate 200.

[0059] like Figure 8 As shown, the two ends of the connecting rod 305 are respectively provided with a first sliding block 3031 and a second sliding block 3032, the first sliding block 3031 and the second sliding block 3032 penetrate the sliding groove 306 and can move along the sliding groove 306, the first sliding block 3031 is connected to the gate 200 at a side away from the connecting rod 305, and the first sliding block 3031 moves horizontally along the sliding groove 306 to drive the gate 200 to reciprocate from upstream to downstream. Among them, the first sliding block 3031 and the second sliding block 3032 are respectively rotatably connected to the two ends of the connecting rod 305.

[0060] The center of the driving elliptical gear 3041 is colinear with the center of the sliding groove 306, that is, the center of the driving elliptical gear 3041 is located on the same center line as the center of the sliding groove 306. The driven elliptical gear 3042 is meshed with the driving elliptical gear 3041 and connected to the connecting rod 305. When the gate 200 is in the initial state, the long diameter of the driving elliptical gear 3041 is perpendicular to the long diameter direction of the driven elliptical gear 3042.

[0061] The driven elliptical gear 3042 is fixedly mounted on the connecting rod 305 through the matching rod 3051. When the connecting rod 305 is located on the left side of the adjustment bracket 300 (i.e., the side close to the upstream), the long diameter of the driven elliptical gear 3042 on the connecting rod 305 is parallel to the horizontal plane, and the long diameter of the driving elliptical gear 3041 is perpendicular to the horizontal plane. The driving elliptical gear 3041 and the driven elliptical gear 3042 are in the form of meshing with special-shaped gears, which ensures that the cleaning bucket 400 runs at a slower speed during the process of launching and discharging water, which helps to better collect garbage and improve the environmental protection effect and work efficiency of the water conservancy project.

[0062] The cleaning bucket 400 is connected to the side of the second sliding block 3032 away from the connecting rod 305 and has an opening. When the active elliptical gear 3041 rotates to drive the driven elliptical gear 3042 to rotate, the second sliding block 3032 moves vertically along the sliding groove 306, so that the cleaning bucket 400 moves up and down under the drive of the second sliding block 3032, and moves from the downstream side of the gate 200 to the upstream side of the gate 200, so that the debris in the upstream liquid enters the cleaning bucket 400 through the opening. Among them, the first sliding block 3031 is fixedly connected to the gate 200, and the second sliding block 3032 is fixedly connected to the cleaning bucket 400.

[0063] In this embodiment, the working process of the lifting water conservancy gate is as follows:

[0064] In the initial state, the long diameter of the driven elliptical gear 3042 is parallel to the horizontal plane, and the long diameter of the driving elliptical gear 3041 is perpendicular to the horizontal plane. When the driving elliptical gear 3041 starts to rotate, the rotation of the driving elliptical gear 3041 drives the driven elliptical gear 3042 meshing therewith to rotate.

[0065] The driven elliptical gear 3042 is connected to the connecting rod 305, so that the first sliding block 3031 and the second sliding block 3032 at both ends of the connecting rod 305 move along the sliding groove 306 on the adjusting bracket 300. When the first sliding block 3031 moves horizontally in the sliding groove 306, the gate 200 connected thereto reciprocates from upstream to downstream. At this time, the gate 200 is not opened, and the water flow from upstream cannot flow to downstream through the gate chamber 100.

[0066] At the same time, the second sliding block 3032 moves vertically in the sliding groove 306, so that the cleaning barrel 400 moves from the downstream side of the gate 200 to the upstream side of the gate 200, so that the upstream debris can enter the barrel through the opening of the cleaning barrel 400, thereby realizing the cleaning function.

[0067] The present invention realizes the coordinated work of the gate 200 and the cleaning bucket 400 by setting an up-and-down staggered linkage mechanism. While the gate 200 moves from upstream to downstream, the cleaning bucket 400 can move up and down, which can not only clean floating objects on the water surface, but also clean the garbage on the bottom of the water, thereby improving the comprehensiveness of the cleaning. In addition, when cleaning the garbage on the bottom of the water, the amount of sediment accumulated near the upstream gate 200 can also be reduced, effectively reducing the pressure on the gate 200 and extending the service life of the gate 200.

[0068] In one embodiment, if Figure 1 and Figure 3 As shown, the lock chamber 100 includes an upstream connecting section 101 and a downstream connecting section 102 .

[0069] One side of the upstream connection section 101 is higher than the upstream liquid level, and an upstream flow channel is provided in the upstream connection section 101. One side of the downstream connection section 102 is connected to the other side of the upstream connection section 101 and is arranged in a step, and the other side is higher than the downstream liquid level, and a downstream flow channel connected to the upstream flow channel is provided in the downstream connection section 102, and a gate 200 is provided in the upstream flow channel.

[0070] The upstream flow channel and the downstream flow channel are located in the same plane, and the top surface of the downstream connecting section 102 is slightly higher than the bottom surface of the downstream flow channel to allow staff to enter.

[0071] The design of the upstream connecting section 101 and the downstream connecting section 102 of the present invention enables water to flow smoothly through the gate 200 , while the step layout facilitates workers to stand on the downstream connecting section 102 to perform operations.

[0072] In one embodiment, if Figure 4 , Figure 6 and Figure 7 As shown, the lifting type hydraulic gate for water conservancy projects also includes a base 301 and a lifting cylinder 302.

[0073] The base 301 is embedded in the gate chamber 100 and has a lifting slot 3011 formed on the base 301. The lifting cylinder 302 is disposed in the lifting slot 3011 and its power output end is connected to the adjusting bracket 300. The adjusting bracket 300 moves along the lifting slot 3011 under the driving of the lifting cylinder 302 to open and close the gate 200.

[0074] In this embodiment, during the opening and closing process of the gate 200, the power output end of the lifting cylinder 302 is connected to the adjusting bracket 300. Through the driving force of the lifting cylinder 302, the adjusting bracket 300 moves along the lifting groove 3011, thereby driving the connecting rod 305 and the gate 200 to rise and fall, thereby realizing the opening and closing of the gate 200.

[0075] The present invention can realize automatic lifting of the adjustment bracket 300 through the driving of the lifting cylinder 302, thereby controlling the opening and closing of the gate 200, and reducing the labor intensity of manual operation.

[0076] In one embodiment, if Figure 6 and Figure 7 As shown, the lifting type hydraulic gate for water conservancy projects also includes an auxiliary frame 307 and a motor 308.

[0077] One end of the auxiliary frame 307 is connected to the lower part of the adjustment bracket 300 and is located on the upper side of the lifting slot 3011, and the other end extends in a direction away from the lifting slot 3011 to the center position of the adjustment bracket 300;

[0078] The motor 308 is arranged on the auxiliary frame 307 and connected to the active elliptical gear 3041. The setting position of the motor 308 corresponds to the center position of the adjustment bracket 300. The motor 308 is used to drive the active elliptical gear 3041 to rotate. The rotation of the active elliptical gear 3041 causes the driven elliptical gear 3042 meshing with it to rotate. The rotation of the driven elliptical gear 3042 causes it to move along the outer edge of the active elliptical gear 3041, and causes the first sliding block 3031 and the second sliding block 3032 on the connecting rod 305 to move along the sliding groove 306 respectively without interfering with each other.

[0079] In this embodiment, the auxiliary frame 307 provides a stable installation position for the motor 308. The motor 308 is connected to the active elliptical gear 3041 through the auxiliary frame 307. The drive of the motor 308 causes the active elliptical gear 3041 to rotate, thereby driving the operation of the entire gate 200 system.

[0080] The arrangement of the auxiliary frame 307 and the motor 308 of the present invention makes the rotation of the active elliptical gear 3041 more stable and accurate, and the driving method of the motor 308 improves the response speed and control accuracy, thereby improving work efficiency.

[0081] In one embodiment, if Figure 6 and Figure 7 As shown, the auxiliary frame 307 includes a first C-frame and a second C-frame.

[0082] The center of the closed end of the first C-shaped frame is connected to the adjustment bracket 300, the open end of the second C-shaped frame is connected to the open end of the first C-shaped frame, the second C-shaped frame is perpendicular to the first C-shaped frame, and the motor 308 is installed at the center of the closed end of the second C-shaped frame.

[0083] In this embodiment, the combination of the first C-frame and the second C-frame forms the structure of the auxiliary frame 307, and the motor 308 is installed at the center of the closed end of the second C-frame. This design provides a stable support structure, making the installation of the motor 308 more stable, and also facilitates the driving of the active elliptical gear 3041 by the motor 308, which helps to improve the stability and durability of the entire device.

[0084] In one embodiment, if Figure 1 and Figure 4 As shown, grooves are respectively provided on opposite sides of the lock chamber 100, and the base 301, the lifting groove 3011 and the auxiliary frame 307 are installed in the grooves, and the grooves are independent of the upstream flow channel. When water flows through the lock chamber 100, the water flow will not enter the grooves, and will not cause damage to the base 301, the lifting groove 3011 and the auxiliary frame 307.

[0085] The adjusting bracket 300 includes a horizontal section and a vertical section in a cross-shaped structure, and the groove includes two oppositely arranged first side walls and two oppositely arranged second side walls, the first side walls are arranged along the flow direction of the water flow, and the two first side walls are parallel to each other. The two second side walls are parallel to each other, and the first side wall is perpendicular to the second side wall.

[0086] The horizontal section is arranged outside the groove, and the two ends of the horizontal section protrude from the two ends of the first side wall. When the lifting cylinder 302 drives the adjusting bracket 300 to move along the lifting groove 3011, the horizontal section of the adjusting bracket 300 is always located outside the groove.

[0087] The size of the auxiliary frame 307 matches the size of the groove, and the auxiliary frame 307 is located outside the lifting groove 3011 when the lifting cylinder 302 is reset.

[0088] In this embodiment, the opening of the groove allows the base 301, the lifting groove 3011 and the auxiliary frame 307 to be embedded in both sides of the lock chamber 100, which saves space and enhances the stability of the structure. The position layout of the adjustment bracket 300, the auxiliary frame 307 and the lifting groove 3011 ensures their stable installation in the groove.

[0089] In one embodiment, if Figure 3 As shown, the cleaning barrel 400 includes a barrel body, a plurality of cleaning blades 401 and a power source.

[0090] An opening is provided on one side of the barrel body, and a connecting shaft is provided in the barrel body. A plurality of cleaning blades 401 are evenly arranged on the outer wall of the connecting shaft. A power source is arranged in the barrel body and connected to the connecting shaft, and the power source is used to drive the cleaning blades 401 to rotate so as to introduce the debris in the upstream liquid into the barrel body from the opening.

[0091] In this embodiment, one end of the cleaning blade 401 is made of a deformable material, and the cleaning blade 401 is located in the barrel. Due to the obstruction of the inner wall of the barrel, the end of the cleaning blade 401 away from the connecting shaft is bent. When the cleaning blade 401 rotates to the opening, the inner wall of the barrel no longer obstructs the cleaning blade 401, and the end of the cleaning blade 401 away from the connecting shaft extends out of the barrel and presents a convex structure to bring garbage and mud into the barrel.

[0092] Specifically, the power source is started, and the power source drives the cleaning blade 401 on the connecting shaft to rotate, so that the cleaning blade 401 introduces the garbage and silt at the opening into the barrel body, thereby increasing the efficiency of guiding and collecting the debris by the cleaning blade 401. At the same time, cleaning the debris and silt accumulated on the upstream bottom of the water can prevent the debris and silt from damaging the gate 200, and also reduce the impact of the debris on the downstream water flow.

[0093] In another embodiment, if Figure 3As shown, the cleaning barrel 400 includes a barrel body and a plurality of cleaning blades 401 .

[0094] An opening is provided on one side of the barrel body, and a filter hole is provided on the outer peripheral wall of the barrel body to allow the upstream liquid to enter the barrel body. A connecting shaft is provided in the barrel body. A plurality of cleaning blades 401 are evenly arranged on the outer wall of the connecting shaft. Under the impact of the upstream liquid, the cleaning blades 401 rotate to introduce the debris in the upstream liquid into the barrel body from the opening.

[0095] In this embodiment, the filter holes opened on the outer wall of the cleaning barrel 400 allow upstream liquid to enter the barrel body, and the cleaning blades 401 rotate under the impact of the upstream liquid, which helps to introduce debris into the barrel body from the opening to achieve the cleaning function.

[0096] In one embodiment, if Figure 3 As shown, the cleaning blade 401 includes a straight plate and a curved plate.

[0097] One end of the straight plate is connected to the connecting shaft, and a filter hole is provided on the straight plate. One end of the curved plate is connected to the other end of the straight plate, and the other end is bent toward the downstream direction, and a filter hole is provided on the curved plate, so that when the upstream liquid impacts the cleaning blade 401 to drive it to rotate, part of the impact force of the upstream liquid on the cleaning blade 401 is unloaded.

[0098] In this embodiment, filter holes are provided on the straight plate and the curved plate of the cleaning blade 401, so that when the upstream liquid impacts the cleaning blade 401, it can not only drive the cleaning blade 401 to rotate, but also unload part of the impact force, reduce damage to the blade, and extend the service life of the blade.

[0099] In summary, the working process of the lifting hydraulic gate for water conservancy projects is as follows:

[0100] During installation, the base 301 and the adjustment bracket 300 are placed in the groove, and the position of the base 301 in the groove is limited by casting. When in use, the gate 200 blocks the upstream water, and the water level cannot exceed the height surface of the upstream connecting section 101. The height surface of the downstream connecting section 102 is set slightly higher than the downstream liquid level to facilitate personnel entry.

[0101] During periodic garbage collection, Figure 5 , Figure 9-11 As shown, the specific process is as follows:

[0102] like Figure 5 As shown, when the device is in the initial state (first state), the gate 200 blocks the upstream water, the long diameter of the driven elliptical gear 3042 is parallel to the horizontal plane, and the long diameter of the driving elliptical gear 3041 is perpendicular to the horizontal plane.

[0103] When cleaning begins, the motor 308 is started, and the output shaft of the motor 308 rotates to drive the driving elliptical gear 3041 to rotate. The rotation of the driving elliptical gear 3041 causes the driven elliptical gear 3042 to move clockwise along the outer edge of the driving elliptical gear 3041 to the top of the driving elliptical gear 3041, so that the major diameter of the driving elliptical gear 3041 is parallel to the horizontal plane, and the major diameter of the driven elliptical gear 3042 is perpendicular to the horizontal plane, as shown in FIG. Fig. 9 As shown, this is the second state of the device.

[0104] In the second state, the gate 200 moves to the right (ie, to the side close to the downstream) to the center of the adjustment bracket 300, and the cleaning bucket 400 moves upward to the top of the gate 200. The two avoid each other during the movement and do not interfere with each other.

[0105] The driving elliptical gear 3041 continues to rotate, and when the driven elliptical gear 3042 moves clockwise along the outer edge of the driving elliptical gear 3041 to the right side of the driving elliptical gear 3041, the long diameter of the driving elliptical gear 3041 is perpendicular to the horizontal plane, and the long diameter of the driven elliptical gear 3042 is parallel to the horizontal plane. Fig.10 As shown, this is the third state of the device.

[0106] In the third state, the gate 200 moves to the right of the cleaning bucket 400 and is located at the rightmost end. At this time, the cleaning bucket 400 is located at the center of the adjustment bracket 300. The gate 200 moves to the right to absorb the garbage to the right, and the mud and garbage at the bottom will also move to the right, but the movement of the gate 200 will not cause water to flow through the gate chamber 100.

[0107] As the active elliptical gear 3041 continues to rotate, the driven elliptical gear 3042 moves clockwise along the outer edge of the active elliptical gear 3041 to the lower right side of the active elliptical gear 3041. At this time, the gate 200 is moved from the rightmost end to the left through the connecting rod 305, and the cleaning bucket 400 moves downward into the water surface and reaches the extreme state to clean the garbage, that is, the gate 200 moving to the left will contact the cleaning bucket 400 moving downward. This is the fourth state of the device.

[0108] In the process of switching from the third state to the fourth state, the gate 200 moving leftward will come into contact with the cleaning bucket 400 moving downward. Fig.11 As shown, when the gate 200 moves from the rightmost end to the left, the cleaning bucket 400 is moved downward to contact the water surface and enter the water through the connecting rod 305. At this time, the power source is started, so that the cleaning blade 401 rotates counterclockwise, and an opening is opened at the bottom of the cleaning bucket 400. The cleaning blade 401 is bent inside the cleaning bucket 400. When the cleaning blade 401 is out of the opening, it forms a convex shape, which helps to bring garbage on the water surface and the bottom of the water into the cleaning bucket 400.

[0109] When the cleaning bucket 400 moves to the bottom, it switches to the fourth state, and the gate 200 contacts the cleaning bucket 400. Then, the cleaning blade 401 stops rotating, the motor 308 rotates in the reverse direction to drive the driving elliptical gear 3041 to reverse, and the driven elliptical gear 3042 moves with it and makes the connecting rod 305 move in the sliding groove 306, so that the cleaning bucket 400 moves upward, and the gate 200 moves rightward to the rightmost end, that is, it is reset to the third state.

[0110] After returning to the position corresponding to the third state, the active elliptical gear 3041 continues to reverse, and the gate 200 and the cleaning bucket 400 are reset to the positions corresponding to the second state and the first state respectively, thereby completing the cleaning work.

[0111] Specifically, when resetting from the fourth state to the third state, the gate 200 moves to the right, and the cleaning bucket 400 moves upward until the gate 200 moves to the rightmost end, at which time the cleaning bucket 400 reaches the center of the adjustment bracket 300 .

[0112] When the third state is reset to the second state, the gate 200 moves to the left, and the cleaning bucket 400 continues to move upward. When the gate 200 moves to the left to the center of the adjustment bracket 300, the cleaning bucket 400 is located directly above the gate 200.

[0113] When resetting from the second state to the first state, the gate 200 continues to move to the left, the cleaning bucket 400 moves downward, and the cleaning bucket 400 is located on the right side of the gate 200. At this time, there is no water on the downstream side of the gate 200, and the cleaning blade 401 starts to rotate again to discharge the garbage inside the cleaning bucket 400, and the subsequent personnel clean up the garbage.

[0114] In the process of cleaning the garbage, the gate 200 moves one cycle, and the cleaning blade 401 rotates one circle inside the cleaning barrel 400.

[0115] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0116] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
