Description

Technical Field

[0001] This application relates to the technical field of water conservancy projects, and in particular to a silt cleaning device for water conservancy projects. Background Art

[0002] River dredging is one of the water conservancy projects. When it rains, rainwater will carry the sediment on the ground into the river, and then it will be deposited at the bottom of the river to become silt. Workers need to regularly dredge the river to prevent the river from being blocked.

[0003] Generally, the water conservancy silt cleaning equipment disclosed in the prior art includes a silt pump, a suction pipe, and a separation tank. The silt pump is installed on the separation tank. The inlet end of the silt pump is connected to the suction pipe, and the outlet end is connected to the separation tank through a pipeline. A filter screen is provided inside the separation tank and below the outlet end of the silt pump. During the actual working process, one end of the suction pipe far from the silt pipe is inserted into the bottom of the river channel. The silt pump is started, and the silt and water in the river channel are pumped into the separation tank through the suction pipe. The silt is intercepted by the filter screen, and the water contained in the silt will pass through the filter screen and be located at the bottom of the separation tank. A drain pipe with a valve can be connected to the bottom of the separation tank to discharge the filtered water back into the river channel.

[0004] In view of the above related technologies, the inventor found that after the suction pipe of the existing water conservancy silt cleaning equipment penetrates into the bottom of the river channel, the pumping position of the suction pipe is relatively fixed, which is not convenient for cleaning the silt at the bottom of the entire river channel. Summary of the Invention

[0005] In order to achieve convenient cleaning of the river channel silt, this application provides a silt cleaning device for water conservancy projects.

[0006] A silt cleaning device for water conservancy projects provided by this application adopts the following technical solutions:

[0007] A silt cleaning device for water conservancy projects includes a separation tank, a silt pump, and a suction pipe. A filtering assembly for separating silt and water is provided inside the separation tank. The suction pipe includes a sleeve and an insertion pipe. One end of the sleeve is connected to the separation tank, and the other end is sleeved on the end of the insertion pipe. The end of the insertion pipe is slidably connected to the inside of the sleeve along the length direction of the sleeve. A driving assembly for driving the insertion pipe to slide along the length direction of the sleeve is provided on the separation tank; the end of the insertion pipe far from the sleeve is inserted into the river channel. The inlet end of the silt pump is connected to the insertion pipe, and the outlet end of the silt pump is connected to the sleeve; A sliding member for driving the separation tank to move is also provided at the bottom of the separation tank.

[0008] By adopting the above technical solution, the sliding member drives the separation box, the sludge pump on the separation box, and the water suction pipe to move integrally to the designated position in the river channel. Then, the sludge pump is started, and the sludge pump extracts sludge and part of the water from the river channel through the insertion pipe and the sleeve, and makes them enter the separation box. Then, the filtration component in the separation box separates the sludge from the water, realizing the cleaning of the sludge in a certain fixed area. Then, the driving component drives the insertion pipe to slide a certain distance away from the sleeve, and then repeats the above operation of extracting sludge, so as to realize the dredging of the river channel during movement through the driving component and the sliding member, and finally realize the convenient dredging of the entire river bottom.

[0009] Preferably, the insertion pipe includes a straight pipe and a bent pipe. The top end of the bent pipe is sleeved on the bottom end of the straight pipe, and the bent pipe is rotatably connected to the bottom end of the straight pipe. The other end of the bent pipe is inserted into the bottom of the river channel. The top end of the straight pipe is slidably connected inside the sleeve. The sludge cleaning device for water conservancy projects further includes a bending component for driving the bent pipe to rotate around the position where it is rotatably connected to the straight pipe.

[0010] By adopting the above technical solution, the bending component drives the bent pipe to rotate, so that the end of the bent pipe far from the straight pipe rotates towards the direction close to the straight pipe. During the rotation, the bent pipe stirs and excavates the sludge at the bottom of the river channel, promoting the sludge at the bottom of the river channel to enter the bent pipe through the pipe orifice of the bent pipe, and optimizing the cleaning effect of the sludge at the bottom of the river.

[0011] Preferably, a spiral conveyor rod is rotatably connected inside the separation box near the sleeve and inside the sleeve. A first motor is arranged on the separation box, and the driving end of the first motor is connected to the spiral conveyor rod. The length direction of the spiral conveyor rod is parallel to the length direction of the sleeve.

[0012] By adopting the above technical solution, the arrangement of the spiral conveyor rod and the first motor can cooperate with the sludge pump to promote the transportation of the sludge from the sleeve to the separation box, so as to improve the treatment efficiency of the sludge.

[0013] Preferably, one end of the insertion pipe far from the sleeve is rotatably connected with a digging plate. One end of the digging plate far from the insertion pipe can be in contact with the bottom wall of the river channel. The sludge cleaning device for water conservancy projects further includes a moving component for driving the digging plate to rotate towards or away from the pipe orifice of the river channel insertion pipe.

[0014] By adopting the above technical solution, the moving component drives the digging plate to move towards the direction close to the pipe orifice of the insertion pipe, so as to stir the sludge at the bottom of the river channel through the digging plate and push the sludge in contact with the digging plate to the pipe orifice of the insertion pipe, so as to further fully extract the sludge at the bottom of the river channel into the separation box.

[0015] Preferably, the movable component includes a transmission pulley set, a telescopic rod, a first connecting rod, a second connecting rod and a slider. The telescopic rod is rotatably connected to the separation box. The transmission pulley set is used to drive the telescopic rod to rotate when the driving end of the first motor rotates. The telescopic direction of the telescopic rod is parallel to the sliding direction of the insertion tube relative to the sleeve. The first connecting rod is connected to the end of the telescopic rod. One end of the first connecting rod away from the telescopic rod is hinged to the second connecting rod. The other end of the second connecting rod is hinged to the slider. The slider is slidably connected to the side wall of the excavation plate.

[0016] By adopting the above technical solution, when the first motor drives the spiral conveyor to rotate, the telescopic rod is driven to rotate through the transmission pulley set. When the telescopic rod rotates, it drives the first connecting rod to rotate around the telescopic rod. During the rotation of the first connecting rod, the second connecting rod is driven to lift, so that the slider slides on the excavation plate, and then drives the excavation plate to rotate, realizing the excavation of the silt at the bottom of the river channel by the excavation plate.

[0017] Preferably, the filtering component includes a first filter screen arranged in the separation box, a scraping plate slidable along the length direction of the first filter screen, and a moving part for driving the scraping plate to move and contact the upper surface of the first filter screen. A silt box is also communicated with the side wall of the separation box. The communication position between the silt box and the separation box is above the first filter screen, and the communication position between the silt box and the separation box is in the moving direction of the scraping plate.

[0018] By adopting the above technical solution, the moving part drives the scraping plate to slide along the length direction of the first filter screen. During the sliding process of the scraping plate, it will scrape the upper surface of the first filter screen to clean the silt on the first filter screen, reduce blockage, and at the same time, it can also push the silt on the first filter screen into the silt box, so as to filter and separate the subsequent silt and water entering the separation box through the first filter screen.

[0019] Preferably, the scraping plate is rotatably connected to the separation box. The moving part includes a rotating rod, bevel gears meshing with each other, and butt gears meshing with each other. One of the bevel gears is sleeved on the end of the spiral conveyor. The other bevel gear and one of the butt gears are coaxially rotatably connected to the separation box. The other butt gear is sleeved on the rotating rod. The rotating rod is rotatably connected to the inside of the separation box. The side wall of the scraping plate is connected to the side wall of the rotating rod. The upper surface of the first filter screen is arc-shaped, and the arc formed by the rotation of the end of the scraping plate coincides with the upper surface of the first filter screen.

[0020] By adopting the above technical solution, when the first motor drives the spiral conveyor rod to rotate, the rotating rod will rotate under the drive of two meshing bevel gears and two meshing docking gears, and then the scraper will rotate around the rotating rod. When the scraper rotates towards the direction close to the first filter screen, since the upper surface of the first filter screen is located on the rotation path of the end of the scraper, the scraper will scrape the upper surface of the first filter screen during rotation, so that the silt intercepted by the first filter screen is scraped into the silt box, realizing the cleaning of the first filter screen.

[0021] Preferably, a relief hole is formed on one side of the scraper facing the spiral conveyor rod, and the diameter of the relief hole is not less than the outer diameter of the spiral conveyor rod; a guiding protrusion is arranged on the upper surface of the first filter screen, the guiding protrusion is located directly below the spiral conveyor rod, and the guiding protrusion is arranged along the radian direction of the upper surface of the first filter screen, and the guiding protrusion can be inserted into the relief hole.

[0022] By adopting the above technical solution, the setting of the relief hole is used to realize the independent rotation of the spiral conveyor rod and the rotating rod, so as to avoid the spiral conveyor rod and the scraper from hindering each other and affecting their smooth rotation. The guiding protrusion is just located at the position where the relief hole of the scraper is located, so as to play a guiding role for the silt, so that the silt can be guided and moved to the upper surface of the first filter screen on both sides of the guiding protrusion, and then most of the silt on the first filter screen can be scraped by the scraper.

[0023] Preferably, a counterweight block is slidably connected to the inner wall of the relief hole along its length direction, a docking notch for inserting the guiding protrusion is formed on the side wall of the counterweight block, and a docking arc surface adapted to fit the surface of the guiding protrusion is arranged on the inner wall of the docking notch.

[0024] By adopting the above technical solution, during the rotation of the scraper around the rotating rod, the counterweight block will reciprocally slide along the length direction of the relief hole under the action of its own weight. Specifically, when the rotating position of the scraper makes the spiral conveyor rod inserted into the relief hole, the counterweight block will move away from the opening of the relief hole under the action of its own weight to realize the relief of the spiral conveyor rod, and when the rotating position of the scraper makes the guiding protrusion inserted into the relief hole, the counterweight block will slide towards the opening of the relief hole under the action of its own weight, so that the guiding protrusion is inserted into the docking notch on the counterweight block. At this time, the docking arc surface fits the surface of the guiding protrusion to realize the scraping and cleaning of the surface of the guiding protrusion.

[0025] Preferably, a swing plate is inserted near the docking notch of the counterweight block, the swing plate is rotatably connected to the inner wall of the docking notch, the docking arc surface is located on the swing plate, a rotating shaft is jointly arranged at the rotating connection between the swing plate and the inner wall of the docking notch, and a return torsion spring is sleeved on the rotating shaft. One end of the return torsion spring is connected to the swing plate, and the other end is connected to the inner wall of the docking notch.

[0026] By adopting the above technical solution, since the butt joint arc surface is arranged on the swing plate, it is easy for the swing plate to be attached with some silt during the process of scraping against the guiding protrusion. At this time, the swing plate is set to be rotatably connected to the inner wall of the butt joint notch, so that the swing plate can rotate relative to the counterweight or the scraper, and the silt attached to its surface can be shaken off during the rotation process, ensuring the scraping effect of the swing plate on the surface of the subsequent guiding protrusion.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The sliding member drives the separation box, the silt pump on the separation box, and the water suction pipe to move as a whole to a designated position in the river channel. Then, the silt pump is started, and silt and part of the water are pumped from the river channel through the silt pump via the insertion pipe and the sleeve pipe and enter the separation box. Then, the filtration assembly in the separation box separates the silt from the water, realizing the silt cleaning of a certain fixed area. Then, the driving assembly drives the insertion pipe to slide a certain distance away from the sleeve pipe and repeats the above operation of pumping silt, so as to realize the dredging during the movement of the river channel through the driving assembly and the sliding member, and finally realize the convenient dredging of the entire bottom of the river channel;

[0029] 2. The moving member drives the scraper to slide along the length direction of the first filter screen. During the sliding process of the scraper, the upper surface of the first filter screen will be scraped, so as to clean the silt on the first filter screen, reduce blockage, and at the same time, the silt on the first filter screen can be pushed into the silt box, so as to filter and separate the subsequent silt and water entering the separation box through the first filter screen.

The filtering assembly 13 includes a first filter screen 131, a scraper 132 and a moving member 133. The scraper 132 is rotatably connected inside the separation box 1. The first filter screen 131 is located below the scraper 132, and the upper surface of the first filter screen 131 is arc-shaped, and the arc radian is exactly the same as the rotation path of the scraper 132 so that when the scraper 132 rotates to be close to the first filter screen 131, it can be attached to the upper surface of the first filter screen 131 to scrape and clean the first filter screen 131 through the scraper 132.

[0042] Referring to Figure 2 , the moving member 133 is used to drive the scraper 132 to rotate. The moving member 133 specifically includes a rotating rod 1331, two meshing bevel gears 1332, and two meshing docking gears 1333.

[0045] Reference Figure 2 The side wall of the separation box 1 is also connected to a sludge box 14 with an open top. The open position of the sludge box 14 is flush with the bottom of the first filter screen 131, so that the sludge on the upper surface of the first filter screen 131 falls into the sludge box 14 under the scraping of the scraper 132. A second filter screen 141 is also provided inside the sludge box 14. The bottom of the sludge box 14 is connected to the bottom of the separation box 1. The second filter screen 141 is used to further drain the sludge in the sludge box 14, so that the separated water is collected again at the bottom of the separation box 1, and the bottom of the separation box 1 can be connected to a water outlet pipe with a valve for regular drainage.

[0046] The implementation principle of the silt cleaning device for water conservancy projects disclosed in Embodiment 1 of this application is as follows: The sliding member 5 drives the separation box 1 to move to one side of the river channel. The lower end of the insertion pipe 32 is inserted into the bottom of the river channel. The first motor 12 and the silt pump 2 are started. The silt pump 2 pumps the silt at the bottom of the river channel through the insertion pipe 32 to the sleeve 31. The spiral conveyor rod 11 rotates driven by the first motor 12 to convey the silt in the sleeve 31 into the separation box 1. The first filter screen 131 in the separation box 1 receives the falling silt and filters the silt and water. The silt falling on the guiding protrusions 134 will slide down to the first filter screens 131 on both sides of the guiding protrusions 134 under the guiding action of the guiding protrusions 134. At the same time, when the rotating scraper 132 turns to the first filter screen 131, it scrapes the first filter screen 131, and the swing plate 1325 is sleeved outside the guiding protrusions 134 and scrapes the guiding protrusions 134 to scrape the silt on the surfaces of the first filter screen 131 and the guiding protrusions 134 into the silt box 14. Then, the second filter screen 141 in the silt box 14 is used to further filter the silt in the silt box 14, and the filtered water will be centrally collected at the bottom of the separation box 1. In summary, after the silt extraction operation at a fixed position in the river channel is completed, the driving component 4 can be used to drive the insertion pipe 32 to slide relative to the sleeve 31 to move the insertion position of the bottom of the insertion pipe 32 in the river channel, and then repeat the above operation to perform the silt extraction work again, so as to realize the convenient dredging of the entire bottom of the river channel.

[0048] The difference between Embodiment 2 and Embodiment 1 of this application is: Referring to Figure 5 , one end bottom wall of the insertion pipe 32 away from the sleeve 31 is rotatably connected with a digging plate 33, and one end of the digging plate 33 away from the insertion pipe 32 is bent towards the direction close to the river channel. The silt cleaning device for water conservancy projects further includes a movable component 7. The movable component 7 includes a transmission pulley group 71, a telescopic rod 72, a first connecting rod 73, a second connecting rod 74 and a slider 75. The transmission pulley group 71 includes two belt pulleys 711 and a belt 712 sleeved on the two belt pulleys 711. One of the belt pulleys 711 is fixedly sleeved on the driving end of the first motor 12, and the other belt pulley 711 is sleeved on one end of the telescopic rod 72. The telescopic rod 72 is rotatably connected to the separation box 1, and the telescopic rod 72 includes an outer tube and an inner rod inserted into the outer tube. The outer tube and the inner rod are key-connected so that the inner rod can slide relative to the length direction of the outer tube and can rotate circumferentially with the outer tube. The other end of the telescopic rod 72 is hinged to the first connecting rod 73, the other end of the first connecting rod 73 is hinged to the second connecting rod 74, the second connecting rod 74 is arranged in the vertical direction, the lower end of the second connecting rod 74 is hinged to the slider 75, and the slider 75 can be a T-shaped block. The slider 75 is slidably connected to the upper surface of the digging plate 33.

[0049] The working principle of the silt cleaning device for water conservancy projects disclosed in Embodiment 2 of this application is as follows: When the first motor 12 is started to drive the spiral conveyor rod 11 to rotate, the telescopic rod 72 will rotate driven by the transmission pulley group 71. The rotation of the telescopic rod 72 will drive the first connecting rod 73 to rotate around the telescopic rod 72, and then the second connecting rod 74 will be lifted or lowered under the pulling of the first connecting rod 73. Furthermore, the second connecting rod 74 will drive the slider 75 to slide on the upper surface of the excavation plate 33, and finally the excavation plate 33 will rotate under the pulling or pressing of the slider 75. When the excavation plate 33 rotates towards the direction close to the bottom wall of the river channel, the excavation plate 33 will excavate and stir the silt at the bottom of the river channel, accelerating the silt to enter the insertion pipe 32 and optimizing the silt cleaning effect.
