Description

Technical Field

[0001] This invention belongs to the technical field of water conservancy engineering and relates to a device for treating sediment in river gates. Background Technology

[0002] In water conservancy projects, river gates are crucial facilities for regulating water flow, flood control, drainage, and water resource management. However, in actual operation, the large amounts of silt carried by natural rivers deposited in front of the gates can easily cause sedimentation at the bottom, affecting the normal opening and closing function of the gates and even leading to equipment damage or malfunctions. Furthermore, silt accumulation can reduce the sealing performance of the gates, increase maintenance costs, and threaten the stability and safety of the entire water conservancy system.

[0003] Currently, the main method for addressing the problem of siltation at river gates is dredging. However, since dredging is usually a periodic operation, silt accumulates over time, and the bottom layer of silt gradually becomes compacted and hardened, further increasing the difficulty of dredging. To improve dredging efficiency, some equipment uses suction pumps to extract the bottom silt. However, suction pumps can only clean the surface silt, while the compacted and hardened silt at the bottom layer is difficult to extract, resulting in poor dredging performance. Summary of the Invention

[0004] In view of this, the present invention provides a device for treating sediment in river gates.

[0005] The technical solution of the present invention is: a sediment treatment device for a river gate, comprising a sediment collection frame, a drainage pipe, a pump, a dredging pipe, a discharge pipe, an extension pipe, a filter screen, an isolation mechanism, and a stirring mechanism. Two sediment collection frames are provided, each located on the upper part of both sides of the dam body. A drainage pipe connects to the lower part of each sediment collection frame. Two pumps are provided, each installed on the top of both sides of the dam body. The inlet end of each pump is connected to the dredging pipe, and the end of the dredging pipe is connected to an extension pipe located below the gate. The outlet end of each pump is connected to the discharge pipe, which is aligned with the sediment collection frame. A filter screen is connected to the lower part of the sediment collection frame. The isolation mechanism is located on the dam body and is used to isolate sediment from other areas. The isolation mechanism is equipped with a stirring mechanism for stirring the sediment.

[0006] Optionally, the isolation mechanism includes a drive motor, a threaded rod, and an isolation frame. There are two drive motors, which are respectively installed on the upper part of both sides of the dam body. The output shaft of the drive motor is connected to a threaded rod, which is rotatably connected to the dam body. The two threaded rods are connected by a threaded isolation frame, which is slidably engaged with the dam body. The lower front part of the isolation frame is open.

[0007] Optionally, the actuation mechanism includes an electric cleaning rod and an electric actuation rod, with the electric cleaning rod rotatably connected to the upper part of the isolation frame and the electric actuation rod installed in the lower part of the isolation frame.

[0008] Optionally, it also includes an impact mechanism, which includes a high-pressure water pump and a spray pipe. Three high-pressure water pumps are evenly spaced on the top of the isolation frame. A spray pipe is connected to the isolation frame. Multiple diversion pipes are evenly spaced at the bottom of the spray pipe. The diversion pipes pass into the interior of the isolation frame. The outlet end of the high-pressure water pump is connected to the spray pipe.

[0009] Optionally, it also includes a gripping mechanism, which includes an arc-shaped baffle and side plates. The arc-shaped baffle is slidably connected to the isolation frame, and side plates are connected to both sides of the top of the isolation frame.

[0010] Optionally, the gripping mechanism further includes a rotating shaft, gears, a dual-axis motor, a belt drive assembly, and an arc-shaped rack. The dual-axis motor is installed on the top of the isolation frame, and a rotating shaft is rotatably connected between the lower parts of the two side plates. A belt drive assembly is connected between the rotating shaft and the two output shafts of the dual-axis motor.

Extension plates are connected to both sides of the cover plate. Inclined grooves are opened on the extension plates, and the extrusion shaft is located in the inclined grooves.

[0012] Optionally, it also includes a liquid inlet frame and a screen, with the liquid inlet frame connected to the top of the isolation frame, the water inlet end of the high-pressure water pump communicating with the liquid inlet frame, and the screen connected to the top of the liquid inlet frame.

[0013] The present invention has the following advantages: 1. When the present invention is used for dredging through the sand pumping pipe and the expansion pipe, the electric lever can be used to clear the hardened mud and sand.

During the cleaning process, if there are large impurities such as stones, the present invention can control the arc-shaped baffle to swing and draw the stones into the space between the isolation frame and the arc-shaped baffle. Then, by controlling the isolation frame to move upward, the stones can be removed, thereby achieving the effect of cleaning stones and other impurities. The cleaning effect achieved is better.

[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0029] A device for treating sediment in river sluice gates, such as Figures 1-3 As shown, the structure includes a slurry collection frame 1, a drainage pipe 2, a material pump 3, a sand pumping pipe 4, a sand discharge pipe 5, an extension pipe 6, a filter screen 7, an isolation mechanism, and a stirring mechanism. Two slurry collection frames 1 are provided, each located on the upper left and right sides of the dam body 100. The lower part of each slurry collection frame 1 is connected to the drainage pipe 2. Two material pumps 3 are provided, each installed on the top left and right sides of the dam body 100. The inlet end of each material pump 3 is connected to the sand pumping pipe 4, and the end of the sand pumping pipe 4 is connected to the extension pipe 6, located in the lower front part of the gate 200. The outlet end of each material pump 3 is connected to the sand discharge pipe 5, which is aligned with the slurry collection frame 1. A filter screen 7 is connected to the lower part of the slurry collection frame 1 to block the pumped-out mud and sand. The isolation mechanism is located on the dam body 100 and is used to isolate the mud and sand from other areas. The isolation mechanism is equipped with a stirring mechanism for stirring the mud and sand.

[0030] like Figure 2 and Figure 3 As shown, the isolation mechanism includes a drive motor 81, a threaded rod 82, and an isolation frame 83. There are two drive motors 81, which are respectively installed on the upper left and right sides of the dam body 100. The output shaft of the drive motor 81 is connected to the threaded rod 82, which is rotatably connected to the dam body 100. The two threaded rods 82 are connected by a threaded connection to the isolation frame 83, which is slidably engaged with the dam body 100. The isolation frame 83 can slide up and down along the dam body 100, and the lower front part of the isolation frame 83 is open.

[0031] like Figure 2 and Figure 3As shown, the actuation mechanism includes an electric cleaning rod 91 and an electric actuation rod 92. The electric cleaning rod 91 is rotatably connected to the upper part of the isolation frame 83, and the electric actuation rod 92 is installed in the lower part of the isolation frame 83.

[0032] When it is necessary to treat the silt at the river gate 200, this device can be installed at the gate 200 and the dam body 100. When treatment is needed, the drive motor 81 can be controlled to rotate the threaded rod 82. As the threaded rod 82 rotates, it can drive the isolation frame 83 downwards via the thread. As the isolation frame 83 moves downwards, it can compress the silt located in front of the gate 200, thus isolating the silt in the lower part of the isolation frame 83. Then, the pump 3 is controlled to operate and extract the silt from the lower part of the isolation frame 83 through the sand extraction pipe 4 and the extension pipe 6, thereby achieving the effect of cleaning the silt. The extracted silt will then pass through the sand discharge pipe 5. When the sediment is discharged into the collection box 1, the sediment will be blocked by the filter screen 7. The water mixed in with the sediment can pass through the filter screen 7 and be discharged back into the river through the drain pipe 2. During the process of pumping in the sediment, the electric lever 92 can be controlled to rotate and move the deposited sediment, breaking up the clumps of sediment so that the expansion pipe 6 and the sand pumping pipe 4 can pump out the sand. Controlling the electric cleaning lever 91 to rotate can clean the sediment attached to the isolation box 83. In this way, the sediment at the river gate 200 can be treated. During the treatment, the clumps of sediment can be broken up to facilitate the operation of the sand pumping pipe 4 to suck in the sediment.

[0033] like Figure 4 As shown, it also includes an impact mechanism, which includes a high-pressure water pump 101 and a spray pipe 102. Three high-pressure water pumps 101 are evenly spaced on the top of the isolation frame 83. The spray pipe 102 is connected to the isolation frame 83. Multiple diversion pipes are evenly spaced at the bottom of the spray pipe 102. The diversion pipes pass into the interior of the isolation frame 83. The outlet end of the high-pressure water pump 101 is connected to the spray pipe 102 so that the high-pressure water pump 101 can draw water from the river and spray it out through the spray pipe 102, spraying it onto the mud and sand inside the isolation frame 83 to impact the mud and sand, causing the mud and sand to be lifted up so that the sand dredging pipe 4 can perform sand dredging work.

[0034] While the electric lever 92 disperses the silt, the high-pressure water pump 101 can also be controlled to draw water from the river channel and spray it onto the silt through the spray pipe 102 to disperse the silt, further facilitating the sand dredging operation of the expansion pipe 6 and preventing silt from caking and hindering the sand dredging work of the expansion pipe 6.

[0035] like Figures 5-8As shown, it also includes a gripping mechanism, which includes an arc-shaped baffle 111, a dual-axis motor 112, a side plate 113, a belt drive assembly 114, a rotating shaft 115, a gear 116, and an arc-shaped rack 117. The arc-shaped baffle 111 is slidably connected to the front side of the isolation frame 83, and the arc-shaped baffle 111 can slide to block the open position of the isolation frame 83. The dual-axis motor 112 is installed on the top of the isolation frame 83, and side plates 113 are connected to the left and right sides of the top of the isolation frame 83. A rotating shaft 115 is rotatably connected between the lower front side of plate 113. The rotating shaft 115 is connected to the two output shafts of the dual-axis motor 112 via belt drive groups 114. Multiple gears 116 are evenly spaced on the rotating shaft 115. Multiple arc-shaped racks 117 are evenly spaced on the arc-shaped baffle 111. The gears 116 mesh with the arc-shaped racks 117 so that the rotation of the gears 116 can drive the arc-shaped racks 117 to move, thereby controlling the sliding of the arc-shaped baffle 111.

[0036] During the cleaning process, if there are stones in the isolation frame 83, the dual-axis motor 112 can be controlled to drive the rotating shaft 115 to rotate via the belt drive group 114. When the rotating shaft 115 rotates, it can drive the gear 116 to rotate. The rotation of the gear 116 drives the arc-shaped baffle 111 to swing downward via the arc-shaped rack 117. When the arc-shaped baffle 111 swings downward, it closes the open position of the isolation frame 83, so that the arc-shaped baffle 111 picks up the stones. Then, the drive motor 81 drives the threaded rod 82 to reverse, thereby driving the isolation frame 83 to move upward via the thread. In this way, the stones blocking the gate 200 can be grabbed, so as to achieve the effect of cleaning the stones simultaneously.

[0037] like Figures 9-11 As shown, it also includes a storage mechanism, which includes a storage frame 121, a cover plate 122, an electric push rod 123, an extension plate 124, and a pressing shaft 125. The storage frame 121 is located on the upper front side of the dam body 100. The cover plate 122 is slidably connected to the top of the storage frame 121 and can slide back and forth along the top of the storage frame 121. There are two electric push rods 123, which are respectively located on the upper left and right sides of the dam body 100. The pressing shaft 125 is connected to the telescopic rod of the electric push rod 123. The extension plates 124 are connected to both the left and right sides of the cover plate 122. The extension plates 124 have inclined grooves. The pressing shaft 125 is located in the inclined grooves so that when the telescopic rod of the electric push rod 123 extends or retracts, it can press the inclined grooves through the pressing shaft 125 to drive the extension plate 124 to move.

[0038] After the isolation frame 83 and the arc-shaped baffle 111 move upward with the stones, the arc-shaped baffle 111 is located above and behind the storage frame 121. At this time, the electric push rod 123 can be controlled to extend and drive the extrusion shaft 125 to move downward. When the extrusion shaft 125 moves downward, it can extrude the inclined groove at the extension plate 124, thereby causing the extension plate 124 to move backward. When the extension plate 124 moves, it can drive the cover plate 122 to move backward. After the cover plate 122 moves backward, it no longer blocks the top of the storage frame 121. Then, the dual-axis motor 112 is controlled to rotate in the opposite direction to open the arc-shaped baffle 111. The retrieved stones will fall into the storage frame 121 along the cover plate 122. The stones are collected through the storage frame 121. After all the stones have fallen into the storage frame 121, the electric push rod 123 is controlled to retract and drive the cover plate 122 to reset.

[0039] like Figure 12 As shown, it also includes a liquid inlet frame 131 and a screen 132. The liquid inlet frame 131 is connected to the rear top of the isolation frame 83. The water inlet end of the high-pressure water pump 101 is connected to the liquid inlet frame 131. The screen 132 is connected to the top of the liquid inlet frame 131.

[0040] When the high-pressure water pump 101 draws water from the river channel, it also draws water from the inlet frame 131. The screen 132 can filter the mud and sand in the water flow to prevent the mud and sand from entering the inlet frame 131, thereby preventing the high-pressure water pump 101 from being obstructed from operating.

[0041] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
