Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of water conservancy engineering, and particularly relates to a river channel silt prevention and self-cleaning device. BACKGROUND

[0002] When the river channel is in a relatively flat area, the silt carried by the river water will gradually deposit and form silt at the bottom of the river bed, thereby reducing the flow rate of the river water. When the silt at the bottom of the river bed is too thick, the river water will also carry silt into farmland, thereby affecting the quality of the farmland. In order to solve the above problems, the silt at the bottom of the river channel needs to be cleaned in a timely manner.

[0003] In the prior art, the river channel silt prevention and self-cleaning device is used to clean the silt at the bottom of the river channel in a regular manner. In use, the technical personnel need to observe the deposition amount of the silt in the river channel, and when the deposition amount of the silt reaches the standard that needs to be cleaned, the silt is discharged by manually opening the gate.

[0004] In this way, the technical personnel need to observe the deposition thickness of the silt in the river channel in a timely manner by naked eyes, and then determine whether the gate needs to be opened according to the thickness of the silt, so that the work process is relatively complicated and is not conducive to improving the work efficiency. SUMMARY

[0005] The purpose of the embodiment of the present application is to provide a river channel silt prevention and self-cleaning device which can automatically detect the thickness of the silt deposited on the ground in the high water level area, and when the thickness reaches the requirement that needs to be cleaned, the device can automatically open the gate leaf and discharge the silt to the low water level area, and the gate leaf can be automatically closed after the silt is cleaned.

[0012] Optionally, the controller further comprises an elastic piece; the two ends of the elastic piece are fixedly connected with the metal block and the fixed cylinder in the telescopic direction.

[0013] Optionally, the fixed cylinder is provided with a trigger key; the trigger key is electrically connected with the driving device; and when the magnet abuts against the top of the fixed cylinder, the trigger key is started.

[0014] Optionally, the guide piece comprises a first guide groove and a second guide groove; the first guide groove is arranged at the top of the fixed rod; the second guide groove is arranged at the top of the fixed cylinder; and the first guide groove and the second guide groove are both sleeved on the first pull rope.

[0015] Optionally, the control column is a cylinder, the mounting hole is a circular hole, and the bottom surface of the control column is provided with a round corner.

[0016] Optionally, the receiving container comprises a receiving groove, a limiting cylinder and a connecting rod, the limiting cylinder is sleeved on the fixed rod and is located above the control column and the receiving groove, the connecting rod connects the receiving groove and the limiting cylinder, and the limiting cylinder is connected with the buoyancy generating element.

[0017] Optionally, the receiving groove is in the shape of a circular truncated cone, the opening of the receiving groove is upward, and the area of the opening is greater than the area of the bottom of the receiving groove.

[0018] Optionally, the buoyancy generating element is a floating ball group, and the floating ball group is connected with the limiting cylinder through a second pull rope.

[0019] Optionally, the floating ball group comprises a plurality of rubber floating balls, and the volume of each rubber floating ball is variable.

[0022] Optionally, the hydraulic cylinder comprises a plurality of hydraulic cylinders.

[0023] Optionally, the bottom of the fixed rod is fixedly connected with a support, the bottom surface of the support is uniformly provided with a plurality of bottom feet, and the plurality of bottom feet extend into the base of the high water level area and are fixedly connected with the base.

[0024] Optionally, the main wall comprises two wall plates that are parallel to each other and are arranged at intervals, and the two wall plates enclose a containing cavity for containing the door leaf.

[0025] In the embodiment, the gate comprises a main wall and a door leaf, the door leaf is inserted into the main wall and is movably connected with the main wall in the vertical direction, and the gate is used for separating or connecting the low water level area and the high water level area. The driving device is connected with the gate and is used for driving the door leaf to move in the vertical direction. Thus, the door leaf can be driven to move in the vertical direction by the driving device, specifically, when the door leaf moves upward, the high water level area is connected with the low water level area, and when the door leaf moves downward, the high water level area is separated from the low water level area. Further, the basic functions of opening and closing of the gate can be met.

[0026] Then, the fixed rod is vertically connected with the base of the high water level area, the bottom of the receiving container is provided with a mounting hole, and the fixed rod penetrates the mounting hole. Thus, the receiving container can move up and down relative to the fixed rod in the vertical direction, and the fixed rod can guide the up and down movement of the receiving container. Then, since the opening of the receiving container is upward, the silt in the high water level area is easily deposited into the receiving container under the carrying of the water flow.

[0027] Then, since the control column is arranged on the fixed rod, the cross section of the control column along the direction perpendicular to the axis of the fixed rod is the same as the cross section of the mounting hole. Thus, when the receiving container is arranged on the control column, the bottom of the receiving container is sealed, and the sludge deposited in the receiving container will continue to increase. When the sludge reaches the preset weight, the receiving container will move downward under the gravity of the sludge, and then be separated from the control column. At this time, since the cross section of the mounting hole is larger than that of the fixed rod, the sludge in the receiving container will flow out from the mounting hole, so that the receiving container is relieved of the gravity of the sludge. Then, since the buoyancy generating member is connected to the receiving container, the buoyancy generating member will provide an upward pulling force to the receiving container due to the buoyancy of water, so that the receiving container can be pulled to move upward. Then, since the limiting ring is arranged on the control column and above the bottom of the receiving container, when the receiving container moves upward, the limiting ring will limit the movement of the receiving container, and then the receiving container returns to the original position.

[0028] In summary, when the sludge in the receiving container reaches the preset weight, the receiving container will move downward and be separated from the control column, at this time, the sludge in the receiving container will flow out, so that the receiving container is relieved of the gravity of the sludge, then the receiving container will move upward again under the pulling force provided by the buoyancy generating member, and finally the receiving container will stop and return to the original position under the action of the limiting ring. With the passage of time, the above process will automatically repeat.

[0029] Then, since the controller is connected to the receiving container, when the receiving container slides downward and the mounting hole is separated from the control column, the controller controls the driving device to drive the door leaf to open, and when the receiving container slides upward and the mounting hole is arranged on the control column, the door leaf is closed to abut against the bottom of the high water level area. Thus, when the above process automatically repeats, the door leaf will be repeatedly opened and closed with the repeated upward and downward movement of the receiving container. When the door leaf is opened, the sludge in the high water level area will be washed away under the driving of the water flow, thereby achieving the effect of cleaning the sludge. The process of cleaning the sludge will be repeated with the repeated upward and downward movement of the receiving container, thereby achieving the purpose of automatically cleaning the sludge, simplifying the work flow, and improving the efficiency of cleaning the sludge.

[0042] The river silt-preventing self-cleaning device 100 provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0043] Figure 1 is a schematic view of the river silt-preventing self-cleaning device 100 provided by the embodiments of the present application when installed in a river, Figure 2 is Figure 1 a structural schematic view of the river silt-preventing self-cleaning device 100 in

[0044] Referring to Figure 1 and Figure 2 , the river silt-preventing self-cleaning device 100 comprises a gate 1, a driving device 2, a detection device 3 and a controller 4. The gate 1 comprises a main wall body 11 and a leaf 12, the leaf 12 is inserted into the main wall body 11 and is movably connected with the main wall body 11 in the vertical direction, and the gate 1 is used to separate or connect a low water level area F and a high water level area E. The driving device 2 is connected to the gate 1 and is used to drive the leaf 12 to move in the vertical direction.

[0045] The detection device 3 comprises a fixed rod 31, a receiving container 32, a control column 33, a limiting ring 34 and a buoyancy generating piece 35. The fixed rod 31 is vertically connected to the bottom of the high water level area E. The bottom of the receiving container 32 is provided with a mounting hole 324, the fixed rod 31 penetrates the mounting hole 324, and the opening of the receiving container 32 is upward. The control column 33 is arranged on the fixed rod 31, and the cross section of the control column 33 in the direction perpendicular to the axis of the fixed rod 31 is the same as the cross section of the mounting hole 324 and is larger than the cross section of the fixed rod 31. The limiting ring 34 is arranged on the control column 33 and is located above the bottom of the receiving container 32. The buoyancy generating piece 35 is connected to the receiving container 32.

[0046] The controller 4 is connected with the receiving container 32. When the receiving container 32 slides downward and the mounting hole 324 is separated from the control column 33, the controller 4 controls the driving device 2 to drive the leaf 12 to open. When the receiving container 32 slides upward and the mounting hole 324 is sleeved on the control column 33, the leaf 12 is closed so that the leaf 12 abuts against the bottom of the high water level area E.

[0047] In the embodiment of the present application, the gate 1 comprises a main wall 11 and a leaf 12, the leaf 12 is inserted into the main wall 11 and is movably connected with the main wall 11 in the vertical direction, the gate 1 is used to separate or connect the low water level area F and the high water level area E. The driving device 2 is connected with the gate 1 and is used to drive the leaf 12 to move in the vertical direction. Thus, the leaf 12 can be driven to move in the vertical direction by the driving device 2, specifically, when the leaf 12 moves upward, the high water level area E is connected with the low water level area, and when the leaf 12 moves downward, the high water level area E is separated from the low water level area. Further, the basic functions of opening and closing of the gate 1 can be met.

[0048] Then, the fixed rod 31 is vertically connected with the base of the high water level area E, the bottom of the receiving container 32 is provided with a mounting hole 324, and the fixed rod 31 penetrates the mounting hole 324. Thus, the receiving container 32 can move up and down relative to the fixed rod 31 in the vertical direction, and the fixed rod 31 can guide the up and down movement of the receiving container 32. Then, since the opening of the receiving container 32 is upward, the silt in the high water level area E is easily deposited into the receiving container 32 under the carrying of the water flow.

[0049] Then, the control column 33 is arranged on the fixed rod 31, and the cross section of the control column 33 in the direction perpendicular to the axis of the fixed rod 31 is the same as the cross section of the mounting hole 324. Thus, when the receiving container 32 is sleeved on the control column 33, the bottom of the receiving container 32 is sealed, and the silt deposited in the receiving container 32 will continue to increase. When the silt reaches the preset weight, the receiving container 32 will move downward under the gravity of the silt, and then is separated from the control column 33. At this time, since the cross section of the mounting hole 324 is larger than the cross section of the fixed rod 31, the silt in the receiving container 32 will flow out from the mounting hole 324, so that the receiving container 32 is reduced by the gravity of the silt. Then, the buoyancy generating piece 35 is connected with the receiving container 32, so that the buoyancy generating piece 35 will provide an upward pulling force to the receiving container 32 due to the buoyancy of water, so as to pull the receiving container 32 to move upward. Then, the limiting ring 34 is arranged on the control column 33 and is located above the bottom of the receiving container 32, so that when the receiving container 32 moves upward, it will be limited by the limiting ring 34, and at this time, the receiving container 32 returns to the original position.

[0050] In summary, when the silt in the receiving container 32 reaches the preset weight, it will move downward and be separated from the control column 33, at this time, the silt in the receiving container 32 will flow out, resulting in the reduction of the gravity of the silt, and then the receiving container 32 will be moved upward again under the action of the pulling force provided by the buoyancy generating piece 35, and finally, the receiving container 32 will be stopped and returned to the original position under the action of the limiting ring 34. With the passage of time, the above process will automatically and repeatedly occur.

[0051] Then, when the receiving container 32 slides downward and the mounting hole 324 is disengaged from the control column 33, the controller 4 controls the driving device 2 to drive the door leaf 12 to open, and when the receiving container 32 slides upward and the mounting hole 324 is sleeved on the control column 33, the door leaf 12 is closed to abut against the bottom of the high water level area E. Thus, when the above process is automatically repeated, the door leaf 12 is repeatedly opened and closed with the repeated upward and downward movement of the receiving container 32. When the door leaf 12 is opened, the silt in the high water level area E is washed away by the water flow, thereby achieving the effect of cleaning the silt. The process of cleaning the silt is repeated with the repeated upward and downward movement of the receiving container 32, thereby achieving the purpose of automatically cleaning the silt, simplifying the work flow, and improving the efficiency of cleaning the silt.

[0052] In the above process, the receiving container 32 is filled with silt because the upper surface of the silt layer on the bottom of the high water level area E is close to the receiving container 32. That is, when the upper surface of the silt layer on the bottom approaches the receiving container 32, the receiving container 32 slides downward and is disengaged from the control column 33, and the controller 4 controls the driving device 2 to drive the door leaf 12 to open, thereby achieving the effect of cleaning the silt. That is, the upper surface of the silt layer is always below the receiving container 32, and thus the thickness of the silt layer can be controlled by controlling the height of the receiving container 32 relative to the bottom.

[0053] It should be noted that the driving device 2 can be a hydraulic cylinder 21 or a jack, or other driving devices 2, which are not limited in the embodiments of the present application.

[0054] It should be further noted that the controller 4 can be a controller 4 controlled by a mechanical structure or a controller 4 controlled by signal transmission, which are not limited in the embodiments of the present application.

[0055] It should be further noted that the buoyancy generating member 35 refers to an object that can exert an upward pulling force on the receiving container 32 when it floats on the water surface because the buoyancy it receives is greater than its weight. The buoyancy generating member 35 can be a floating ball or a foam block, or other objects with the same function, which are not limited in the embodiments of the present application.

[0056] Optionally, in some embodiments, referring to Figure 2 and Figure 3The controller 4 comprises a fixed cylinder 41, a first pull rope 42, a guide 43, a magnet 44, and a metal block 45. The first pull rope 42 passes through the guide 43 and the fixed cylinder 41 to connect the receiving container 32 and the magnet 44. The magnet 44 is located at the end of the first pull rope 42 and is suspended in the interior of the fixed cylinder 41. The metal block 45 is connected to the fixed cylinder 41 and is located below the magnet 44. The magnet 44 and the metal block 45 are attracted to or separated from each other. When the magnet 44 abuts against the top of the fixed cylinder 41, the controller 4 controls the driving device 2 to drive the door leaf 12 to open. The guide 43 is used to change the extension direction of the first pull rope 42, so that the two ends of the first pull rope 42 move in opposite directions.

[0057] In the embodiment, the first pull rope 42 passes through the guide 43 and the fixed cylinder 41 to connect the receiving container 32 and the magnet 44. The magnet 44 is located at the end of the first pull rope 42 and is suspended in the interior of the fixed cylinder 41.

[0058] In this way, when the receiving container 32 moves downward relative to the base of the high water level area E, the magnet 44 is driven by the first pull rope 42 and moves upward. When the receiving container 32 moves downward and is separated from the control column 33, the magnet 44 abuts against the top of the fixed cylinder 41. Then, when the magnet 44 abuts against the top of the fixed cylinder 41, the controller 4 controls the driving device 2 to drive the door leaf 12 to open. In this way, the control effect that the door leaf 12 automatically opens when the receiving container 32 moves downward and is separated from the control column 33 is achieved.

[0059] Then, the metal block 45 is connected to the fixed cylinder 41 and is located below the magnet 44. The magnet 44 and the metal block 45 are attracted to or separated from each other. In this way, when the receiving container 32 moves upward, the metal block 45 can attract the magnet 44 and provide an upward pulling force to the receiving container 32 along the direction of the first pull rope 42, thereby controlling the door leaf 12 to close.

[0060] It should be noted that the first pull rope 42 can be a metal wire or a plastic wire, or other devices with the same function, which is not limited in the embodiment.

[0061] It should be further noted that the metal block 45 must be made of a metal that can be magnetized to ensure that it can be attracted to the magnet 44.

[0062] Optionally, in some embodiments, referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the controller 4 further comprises an elastic member 46. The two ends of the elastic member 46 are fixedly connected to the metal block 45 and the fixed cylinder 41 in the extension and retraction direction.

[0063] In the embodiment of the present application, the magnet 44 and the metal block 45 are attached together under the action of the magnetic force when the door leaf 12 is closed. When a certain amount of sludge is deposited in the receiving container 32, the receiving container 32 will move downward under the action of the gravity of the sludge, and then drive the magnet 44 to move upward through the first pull rope 42. At this time, since the two ends of the elastic member 46 are fixedly connected with the metal block 45 and the fixed cylinder 41 along the extension direction, the elastic member 46 will be stretched, and the magnet 44 will not be separated from the metal block 45. When the sludge continues to be deposited to a preset mass, the magnet 44 will be separated from the metal block 45. In this process, the receiving container 32 gradually moves downward. If the spring is not provided, the metal block 45 is directly fixedly connected with the fixed cylinder 41. Only when the sludge deposited in the receiving container 32 reaches the preset mass, the magnet 44 will be separated from the metal block 45 and move upward instantaneously. Therefore, in this process, the receiving container 32 moves downward instantaneously. Compared with the scheme that the receiving container 32 moves downward instantaneously, the scheme that the receiving container 32 gradually moves downward can reduce the tension of the first pull rope 42, and then reduce the risk of damage of the first pull rope 42, and prolong the service life of the first pull rope 42.

[0064] In addition, the gradual downward movement of the receiving container 32 can make the receiving container 32 deposit more sludge, that is, the deposition time of the sludge on the base can be prolonged each time, and then more sludge can be taken away each time the door leaf 12 is opened, the opening frequency of the door leaf 12 is reduced, and the ecological stability of the water area is beneficial to maintaining.

[0065] In order to make the elastic member 46 be able to stretch and contract along the vertical direction, a circular plate is fixedly arranged in the fixed cylinder 41, a circular hole is formed in the circular plate, the iron block is slidingly arranged in the circular hole, and the elastic member 46 connects the iron block and the bottom of the circular hole. In this way, the circular hole can play a guiding role when the elastic member 46 stretches and contracts along the vertical direction.

[0066] It should be noted that the elastic member 46 can be a spring or an elastic rubber strip, or other elastic members 46 with the same function, and the embodiment of the present application does not limit the same.

[0067] Optionally, in some embodiments, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5The fixed cylinder 41 is provided with a trigger key 47, which is electrically connected with the driving device 2, and the trigger key 47 is started when the magnet 44 abuts against the top of the fixed cylinder 41. In this way, when the receiving container 32 moves to just separate from the control column 33, the magnet 44 is moved upward by the first pull rope 42 to the position of abutting against the top of the fixed cylinder 41, at which time the trigger key 47 can be started, and then the trigger key 47 can start the driving device 2 to drive the door leaf 12 to open, so as to clean the silt of the bottom. Since the magnet 44 will be moved upward by the first pull rope 42 to the position of abutting against the top of the fixed cylinder 41 when the receiving container 32 moves to just separate from the control column 33, and then the trigger key 47 will be started, and then the door leaf 12 will be opened, the reliability of the controller 4 is improved.

[0068] It should be noted that the trigger key 47 can be arranged at the abutting position of the top of the fixed cylinder 41, or can be arranged at other positions in the fixed cylinder, which is not limited in the embodiments of the present application.

[0069] It should be noted that the trigger key 47 can be a pressure-sensitive resistor or a touch switch, or can be other devices with the same function, which is not limited in the embodiments of the present application.

[0070] Optionally, in some embodiments, referring to Figure 2 , Figure 3 and Figure 4 , the guide member 43 comprises a first guide slot 431 and a second guide slot 432, the first guide slot 431 is arranged at the top of the fixed rod 31, and the second guide slot 432 is arranged at the top of the fixed cylinder 41, and the first guide slot 431 and the second guide slot 432 are both slidably sleeved on the first pull rope 42. In this way, when the first pull rope 42 passes through the first guide slot 431, the extension direction of the first pull rope 42 changes by an angle, and when the first pull rope 42 passes through the second guide slot 432, the extension direction of the first pull rope 42 changes by another angle, and after the two times of direction change, the moving directions of the two ends of the first pull rope 42 are opposite, so as to ensure that the moving directions of the receiving container 32 and the magnet 44 are opposite. Compared with the scheme comprising only one guide slot, it is easier to make the first pull rope 42 slide around the guide member 43, and thus the controller 4 is more sensitive.

[0071] Optionally, in some embodiments, referring to Figure 5 , Figure 2 , Figure 3 and Figure 4 , the control column 33 is a cylindrical column, the mounting hole 324 is a circular hole, and the bottom surface of the control column 33 is provided with a round corner.

[0072] The cross section of the cylinder is the same shape and size as the circular hole. Compared with the case where the cross section of the control cylinder 33 and the mounting hole 324 are set to other shapes, even when the receiving container 32 rotates around the axis of the mounting hole 324 under the action of water flow, the receiving container 32 can be smoothly sleeved on the control cylinder 33 during upward movement, thereby making the performance of the detection device 3 more stable.

[0073] In addition, the bottom surface of the control cylinder 33 is provided with a rounded corner. Compared with the case where the bottom of the control cylinder 33 is not provided with a rounded corner, the control cylinder 33 is easier to be sleeved on when the receiving container 32 moves upward, thereby making the receiving container 32 easier to return to the original position, the door leaf 12 easier to be closed, and the opening and closing of the door leaf 12 more smooth.

[0074] Optionally, in some embodiments, referring to Figure 5 , Figure 2 , Figure 3 and Figure 2 , the receiving container 32 comprises a receiving groove 321, a limiting cylinder 322, and a connecting rod 323. The limiting cylinder 322 is sleeved on the fixed rod 31 and located above the control cylinder 33 and the receiving groove 321. The connecting rod 323 connects the receiving groove 321 and the limiting cylinder 322. The limiting cylinder 322 is connected with the buoyancy generating member 35.

[0075] In the embodiments, the limiting cylinder 322 is sleeved on the fixed rod 31, so that the limiting cylinder 322 can slide up and down along the fixed rod 31. Then, since the limiting cylinder 322 is located above the control cylinder 33 and the receiving groove 321 and the connecting rod 323 connects the receiving groove 321 and the limiting cylinder 322, when the limiting cylinder 322 slides up and down along the fixed rod 31, the receiving groove 321 can be driven to slide up and down by the connecting rod 323, thereby guiding the movement of the receiving groove 321. Then, since the limiting cylinder 322 is connected with the buoyancy generating member 35, when the buoyancy generating member 35 exerts an upward pulling force on the limiting cylinder 322, the limiting cylinder 322 can be driven to move upward, thereby driving the receiving groove 321 to move upward. The limiting cylinder 322 and the buoyancy generating member 35 are connected by the second pulling rope 37. The connecting rod 323 between the receiving groove 321 and the limiting cylinder 322 is distributed in a circumferential array.

[0076] It should be noted that the receiving groove 321 is an upwardly open container, which is a container directly used for containing sludge. The bottom of the receiving groove 321 is provided with a mounting hole 324.

[0077] Optionally, in some embodiments, referring to Figure 3 and Figure 2The receiving groove 321 is in the shape of a circular truncated cone, and the opening of the receiving groove 321 is upward and has a larger area than the bottom of the receiving groove 321. The silt carried by the water flow is gradually deposited from the upper part of the receiving groove 321 to the inside of the receiving groove 321. This makes the receiving groove 321 more easily collect silt, thereby shortening the time required for the silt in the receiving groove 321 to reach the preset quality, thereby making the detection device 3 more sensitive, and thus improving the reliability of the self-cleaning device 100.

[0078] Optionally, in some embodiments, referring to Figure 3 and Figure 2 , the buoyancy generating member 35 is a group of floating balls, and the group of floating balls is connected to the limiting cylinder 322 through the second pull rope 37. Since the floating ball is a common floating member, using the group of floating balls as the buoyancy generating member 35 can reduce the manufacturing cost of the self-cleaning device 100. In addition, since the surface of the floating ball is spherical, when the floating ball rotates in the water, the change in the buoyancy it receives is small, thereby making the change in the pulling force of the receiving groove 321 small. This makes the pulling force on the receiving groove 321 always relatively balanced.

[0079] Optionally, in some embodiments, referring to Figure 3 and Figure 1 , the group of floating balls includes a plurality of rubber floating balls, and the volume of the rubber floating ball is variable.

[0080] Since rubber has good corrosion resistance, using rubber floating balls to form the group of floating balls can enhance the corrosion resistance of the group of floating balls, thereby prolonging the service life of the group of floating balls.

[0081] In addition, since the volume of the rubber floating ball is variable. This can adjust the volume of the rubber floating ball according to the mass of silt that the receiving container 32 can accommodate, thereby adjusting the volume of the group of floating balls to adapt to different river channels, thereby increasing the application range of the river silt prevention and self-cleaning device 100.

[0082] Optionally, in some embodiments, referring to Figure 2 and Figure 6 , the second pull rope 37 is a plurality of, and each second pull rope 37 is connected to one rubber floating ball.

[0083] In this way, during the use of the river silt prevention and self-cleaning device 100, even if part of the second pull rope 37 is accidentally broken, part of the rubber floating ball will still be connected to the limiting cylinder 322, so that the entire group of floating balls will not be lost, and the river silt prevention and self-cleaning device 100 can still operate normally. Therefore, the stability of the river silt prevention and self-cleaning device 100 is enhanced.

[0084] Optionally, in some embodiments, referring to Figure 1 , Figure 2and Figure 6 The driving device 2 comprises a hydraulic cylinder 21, a cylinder body 211 of the hydraulic cylinder 21 is fixedly connected with the main wall 11, and a piston 212 of the hydraulic cylinder 21 is fixedly connected with the leaf 12.

[0085] In the embodiment, the hydraulic cylinder 21 is a common telescopic component, and the pulling force is large when the hydraulic cylinder 21 is telescoped, so that the driving force requirement can be met when the hydraulic cylinder 21 is installed on the gate 1 and used to drive the leaf 12 to rise and fall. Accordingly, when the leaf 12 needs to be opened, the piston 212 moves towards the cylinder body 211, thereby driving the leaf 12 to rise, at this time, the high water level area E is communicated with the low water level area F, and the silt is washed from the high water level area E to the low water level area F by the water flow. When the leaf 12 needs to be closed, the piston 212 moves away from the cylinder body 211, thereby driving the leaf 12 to fall, at this time, the high water level area E is separated from the low water level area F.

[0086] Optionally, in some embodiments, referring to Figure 1 , Figure 2 and Figure 1 , the hydraulic cylinder 21 is multiple.

[0087] In this way, the driving device 2 has greater driving force when driving the leaf 12 to move, thereby enabling the leaf 12 to rise or fall more easily.

[0088] In addition, when part of the hydraulic cylinders 21 fails, the other hydraulic cylinders 21 can work normally, without affecting the normal operation of the river silt prevention and self-cleaning device 100. Therefore, the stability of the river silt prevention and self-cleaning device 100 is enhanced.

[0089] It should be noted that the number of the hydraulic cylinders 21 can be two, three or more, which is not limited in the embodiment.

[0090] Optionally, in some embodiments, referring to Figure 2 and ​ , the bottom of the fixed rod 31 is fixedly connected with a support 36, the bottom surface of the support 36 is uniformly provided with a plurality of feet 361, and the plurality of feet 361 extends into the base of the high water level area E and is fixedly connected with the base. In comparison with the scheme of directly connecting the fixed rod 31 with the base, the support 36 arranged at the bottom of the fixed rod 31 can make the fixed rod 31 more firmly connected with the base, thereby increasing the reliability of the detection device 3.

[0091] It should be noted that the support 36 can be a cross support 36, a triangular support 36 or other types of supports 36, which is not limited in the embodiment.

[0092] Optionally, in some embodiments, referring to ​ and ​The main wall body 11 comprises two wallboards which are parallel and spaced apart, and the two wallboards enclose a containing cavity for containing the door leaf 12.

[0093] When the door leaf 12 moves upward, it extends into the containing cavity. Since the containing cavity is enclosed by two parallel wallboards, the shape of the containing cavity is plate-shaped, which can match the shape of the door leaf 12, and thus the lifting movement of the door leaf 12 is more convenient.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions described in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
