Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy silt clearing and dredging device. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. During the construction of water conservancy projects, it is necessary to clean up the silt deposited at the bottom of the river, and dredging devices are often used to extract and dredge the silt.

[0003] The current silt removal and dredging device uses a sludge pump and a pipeline to extract silt. The pipeline at the sewage extraction end of the sludge pump needs to be placed in the silt, and the silt is extracted by the sludge pump. The fluidity of the upper silt is strong, and the fluidity of the bottom silt is poor. During the silt extraction process, it is possible to be blocked by the silt with poor fluidity. After the single-tube silt extraction pipeline is blocked, it needs to be removed and cleaned, which is relatively complicated and may affect its silt removal and dredging efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a hydraulic silt clearing and dredging device which can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A hydraulic silt clearing and dredging device comprises: a casing, and also comprises: a sludge pump fixed in the casing; a first sludge pipe fixed on the lower side of the casing, and the first sludge pipe is connected to the input end of the sludge pump; two second sludge pipes are symmetrically arranged on the first sludge pipe; a first solenoid valve is arranged in the second sludge pipe; a controller is fixed in the casing; a first discharge pipe is arranged at the output end of the sludge pump; a second discharge pipe is fixed on the upper side of the casing, and the second discharge pipe is connected to the first discharge pipe.

[0007] In order to facilitate improving the fluidity of the sludge, further, a water pump is fixedly connected in the box body, the input end of the water pump is fixedly connected to a water suction pipe, the output end of the water pump is fixedly connected to a drainage pipe, water supply pipes are symmetrically arranged on the drainage pipe, and one end of the water supply pipe is connected to the second sludge pipe, and the end of the water supply pipe close to the second sludge pipe is arranged on the side of the first solenoid valve away from the first sludge pipe.

[0008] In order to facilitate the control of the water supply pipe, a second solenoid valve is further provided in the water supply pipe.

[0009] Preferably, a sliding tube is sealingly slidably disposed between the first discharge tube and the second discharge tube, a retaining ring is fixedly connected inside the sliding tube, and a detection assembly is disposed on the outer side of the sliding tube.

[0010] In order to facilitate the detection of whether the second sludge pipe is blocked, the detection assembly further includes a first fixed plate fixed on the box body and a second fixed plate fixed on the sliding tube, a tension spring is fixedly connected between the first fixed plate and the second fixed plate, a limiting plate is fixedly connected to the box body, a first conductive block is fixedly connected to the limiting plate, and a second conductive block matching the first conductive block is fixedly connected to the second fixed plate.

[0011] In order to facilitate the support of the box body, further, a plurality of supporting legs are symmetrically fixedly connected to the lower side of the box body.

[0012] Compared with the prior art, the utility model provides a water conservancy silt clearing and dredging device, which has the following beneficial effects:

[0013] 1. The hydraulic desilting and dredging device opens the sludge pump and the first solenoid valve in one of the second silt pipes through a controller. The sludge pump performs silt extraction through the first silt pipe and one of the second silt pipes, and discharges the silt through the first discharge pipe and the second discharge pipe. When the second silt pipe being extracted is blocked, the first solenoid valve in another second silt pipe is controlled to open through the controller, and then the first solenoid valve in the blocked second silt pipe is closed, thereby effectively preventing the silt extraction from a single pipeline from being blocked and affecting the desilting operation.

[0014] 2. The hydraulic desilting and dredging device controls the water pump to pump water through a controller, and then controls the second solenoid valve in the water supply pipe close to the side of the second silt pipe that has not been pumped out to open through the controller. The water pump slowly transports water to the second silt pipe that has not been pumped out, so that the silt with poor fluidity can be replenished with water, thereby effectively improving the desilting efficiency and effectively preventing the second silt pipe from being blocked.

[0015] 3. The hydraulic silt clearing and dredging device controls the first solenoid valve in another second silt pipe to open through a controller, and then closes the first solenoid valve in the blocked second silt pipe, and the controller closes the second solenoid valve, and then opens the second solenoid valve in the water supply pipe close to the blocked second silt pipe. At the same time, the controller regularly increases the water supply speed of the water pump, and the water flow backwashes the blocked second silt pipe, so that the operation can be circulated, which effectively improves the silt clearing efficiency.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model effectively prevents the silt removal operation from being affected by the blockage of a single pipeline, and backwashes the blocked second silt pipe and replenishes water for the silt with poor fluidity through water flow, thereby effectively improving the silt removal efficiency and effect.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1: Reference Figure 1-Figure 4 The hydraulic desilting and dredging device comprises: a casing 1, and also comprises: a sludge pump 2, which is fixed in the casing 1; a first sludge pipe 201, which is fixed in the lower side of the casing 1, and the first sludge pipe 201 is communicated with the input end of the sludge pump 2; two second sludge pipes 202, which are symmetrically arranged on the first sludge pipe 201; a first solenoid valve 203, which is arranged in the second sludge pipe 202; a controller 101, which is fixed in the casing 1; a first discharge pipe 204, which is arranged at the output end of the sludge pump 2; a second discharge pipe 205, which is fixed in the upper side of the casing 1, and the second discharge pipe 205 is communicated with the first discharge pipe 204.

[0024] A plurality of supporting legs 102 are symmetrically fixedly connected to the lower side of the box body 1 .

[0025] A water pump 4 is fixedly connected in the box body 1, and the input end of the water pump 4 is fixedly connected to a water suction pipe 401, and the output end of the water pump 4 is fixedly connected to a drainage pipe 402. A water supply pipe 403 is symmetrically arranged on the drainage pipe 402, and one end of the water supply pipe 403 is connected to the second sludge pipe 202. The end of the water supply pipe 403 close to the second sludge pipe 202 is arranged on the side of the first solenoid valve 203 away from the first sludge pipe 201.

[0026] A second solenoid valve 404 is disposed in the water supply pipe 403 .

[0027] When hydraulic desilting and dredging is performed on a river channel, the box body 1 is placed at the silt and supported by a plurality of supporting legs 102. The sludge pump 2 and the first solenoid valve 203 in one of the second silt pipes 202 are turned on by the controller 101. The sludge pump 2 performs silt extraction through the first silt pipe 201 and one of the second silt pipes 202, and discharges the silt through the first discharge pipe 204 and the second discharge pipe 205. When the second silt pipe 202 being desilted is blocked, the first solenoid valve 203 in the other second silt pipe 202 is controlled to open by the controller 101, and then the first solenoid valve 203 in the blocked second silt pipe 202 is closed, thereby effectively preventing the silt extraction from being blocked in a single pipeline and affecting the desilting operation.

[0028] During the silt pumping operation, the controller 101 controls the water pump 4 to pump water, and then the controller 101 controls the second solenoid valve 404 in the water supply pipe 403 close to the side of the second silt pipe 202 that has not been pumped out to open, and the water pump 4 slowly transports water to the second silt pipe 202 that has not been pumped out, so that the silt with poor fluidity can be replenished with water, thereby effectively improving the dredging efficiency and effectively preventing the second silt pipe 202 from being blocked.

[0029] When the second silt pipe 202 for silt extraction is blocked, the controller 101 controls the first solenoid valve 203 in another second silt pipe 202 to open, and then closes the first solenoid valve 203 in the blocked second silt pipe 202, and the controller 101 closes the second solenoid valve 404, and then opens the second solenoid valve 404 in the water supply pipe 403 close to the blocked second silt pipe 202. At the same time, the controller 101 regularly increases the water supply speed of the water pump 4, and the water flow backwashes the blocked second silt pipe 202, so that the cycle operation can be achieved, which effectively improves the dredging efficiency.

[0030] Example 2: Reference Figure 1-Figure 4The hydraulic desilting and dredging device is basically the same as that of Example 1. Furthermore, a sliding tube 206 is sealed and slidably provided between the first discharge pipe 204 and the second discharge pipe 205, a retaining ring 207 is fixedly connected inside the sliding tube 206, and a detection component is provided on the outer side of the sliding tube 206.

[0031] The detection component includes a first fixed plate 208 fixed on the box body 1 and a second fixed plate 209 fixed on the sliding tube 206, a tension spring 210 is fixedly connected between the first fixed plate 208 and the second fixed plate 209, a limiting plate 3 is fixedly connected to the box body 1, a first conductive block 301 is fixedly connected to the limiting plate 3, and a second conductive block 302 matching the first conductive block 301 is fixedly connected to the second fixed plate 209.

[0032] When detecting whether the second sludge pipe 202 is blocked, if the second sludge pipe 202 is in a cleared state, the sludge flowing out of the first discharge pipe 204 flows upward, thereby generating an impact force on the retaining ring 207, causing the sliding pipe 206 to move upward and pull the tension spring 210. If the second sludge pipe 202 is blocked, the amount of sludge flowing out of the first discharge pipe 204 is reduced, and the sliding pipe 206 moves downward under the action of the tension spring 210. At this time, the sliding pipe 206 drives the second fixed plate 209 to move downward, so that the first conductive block 301 contacts the second conductive block 302. At this time, the controller 101 receives the current signal of the circuit where the first conductive block 301 and the second conductive block 302 are located, so that the blockage signal of the second sludge pipe 202 can be obtained, and the corresponding first solenoid valve 203 and the second solenoid valve 404 are opened and closed. The fully automated detection can timely replace the second sludge pipe 202 for silt extraction operations, thereby effectively improving its dredging effect and dredging efficiency.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
