Description

Technical Field

[0001] The present invention belongs to the technical field of dam dredging, and particularly relates to a dredging device and a treatment system for a dam in a water conservancy and hydropower project. Background Art

[0002] After a dam has been used for a long time, the silt at the bottom of the reservoir will gradually increase with the increase of the service time. The accumulated silt will cause the volume of the reservoir to gradually decrease, greatly reducing the regulation capacity and power generation capacity of the dam reservoir. Therefore, regular dredging work is required.

[0003] Currently, when carrying out dredging work, the method of combining a mud pump and a stirrer is generally used for dredging. The stirrer is used to stir the silt so that it can be pumped out through the mud pump. However, since most reservoirs of water conservancy and hydropower dams are designated as water source protection areas, the traditional method of using a mud pump in combination with a stirrer to pump and dredge water conservancy and hydropower dams will stir the silt at the bottom of the reservoir during cleaning, thereby causing fine particles, pollutants, and harmful substances in the silt to spread outwards, which will have a long-term impact on water resources. Moreover, there is a lot of deposited garbage in the silt, such as branches and domestic garbage. The stirrers traditionally installed on both sides of the mud pump can only stir the silt and cannot screen and block the garbage. The garbage combined with the silt with a relatively high viscosity is extremely likely to cause blockage of the mud pump or pipeline, and it is not convenient for actual use. Summary of the Invention

[0004] The purpose of the present invention is to provide a dredging device and a treatment system for a dam in a water conservancy and hydropower project to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solution: A dredging device and a treatment system for a dam in a water conservancy and hydropower project include a mud pump. A supplementary cylinder is fixedly sleeved on the output end of the mud pump. A plug board is fixedly installed at the port of the supplementary cylinder. A water pump is fixedly installed at the bottom of the supplementary cylinder near the mud pump. An inspection pipe is fixedly installed at the input end of the water pump. The inspection pipe extends to both sides of the supplementary cylinder, and small holes are equally spaced on the inspection pipe. The output end of the water pump is communicated with a first water pipe and a second water pipe through a connecting pipe. The connecting pipe, the first water pipe, and the second water pipe are all located below the supplementary cylinder. High-pressure nozzles are equally spaced on the first water pipe and the second water pipe. The ports of the high-pressure nozzles penetrate through the supplementary cylinder and extend into the interior of the supplementary cylinder. Connecting plates are symmetrically installed on the outer wall of the supplementary cylinder near the mud pump.

A motor is fixedly installed inside the installation grooves. Transmission holes are symmetrically formed on the left and right sides of the additional cylinder. The transmission holes are located between the sludge suction pump and the plug board. A stirring rod passes through the two transmission holes. The stirring rod is connected to the output end of the motor. A bearing is fixedly installed inside the transmission hole. The bearing is sleeved at both ends of the stirring rod.

[0007] Preferably, two fitting grooves are formed at the bottom of the additional cylinder. Both the first water pipe and the second water pipe are fitted inside the fitting grooves. The first water pipe is located between the stirring rod and the plug board. A diversion plate is fixedly installed on the inner wall of the additional cylinder. The diversion plate is located directly above the first water pipe. And the side of the first water pipe close to the sludge suction pump is of an arc structure.

[0008] Preferably, an inclined filter plate is fixedly installed on the inner wall of the additional cylinder. The filter plate is located between the stirring rod and the sludge suction pump. The second water pipe is located between the stirring rod and the filter plate. A discharge port is formed at the top of the additional cylinder.

The waste material groove communicates with the additional cylinder through the discharge port.

[0009] Preferably, discharge ports are symmetrically formed at the lower part of the side of the attachment close to the sludge suction pump. A cover plate is fitted inside the discharge ports. The cover plate is used to control the opening and closing of the discharge ports. Two inclined guiding plates are symmetrically installed at the top of the inner wall of the waste material groove.

[0011] Preferably, multiple pipes are fitted inside a single fitting groove. And multiple perforations are alternately formed at equal intervals above the inner wall of the fitting groove. The high-pressure nozzle passes through the perforations and extends into the additional cylinder.

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1-3 andFigure 5 As shown in the figure, the present invention provides the following technical solution: A dredging device and treatment system for a dam of a water conservancy and hydropower project includes a sludge pump 13. A supplementary cylinder 2 is fixedly installed by sleeving on the output end of the sludge pump 13. A plug plate 9 is fixedly installed at the port of the supplementary cylinder 2. And a water pump 12 is fixedly installed at the bottom on one side of the supplementary cylinder 2 close to the sludge pump 13. An inspection pipe 18 is fixedly installed at the input end of the water pump 12. The inspection pipe 18 extends to both the left and right sides of the supplementary cylinder 2. And small holes are equidistantly arranged on the inspection pipe 18. The output end of the water pump 12 is communicated with a first water pipe 10 and a second water pipe 25 through a connecting pipe 11. The connecting pipe 11, the first water pipe 10 and the second water pipe 25 are all located below the supplementary cylinder 2. And high-pressure nozzles 15 are equidistantly installed on the first water pipe 10 and the second water pipe 25. The port of the high-pressure nozzle 15 penetrates through the supplementary cylinder 2 and then extends into the supplementary cylinder 2. Symmetrically installed on the outer wall on one side of the supplementary cylinder 2 close to the sludge pump 13 are connecting plates 1. A U-shaped accessory 3 is fixedly installed on the outer wall of the supplementary cylinder 2. Installation grooves 22 are symmetrically opened on the inner wall of the accessory 3. A motor 14 is fixedly installed inside the installation grooves 22. Transmission holes 23 are symmetrically opened on both the left and right sides of the supplementary cylinder 2. The transmission holes 23 are located between the sludge pump 13 and the plug plate 9. And a stirring rod 7 passes through the two transmission holes 23. The stirring rod 7 is connected to the output end of the motor 14. Bearings 27 are fixedly installed inside the transmission holes 23. The bearings 27 are sleeved on both ends of the stirring rod 7.

[0019] Through the above technical solution, during use, the supplementary cylinder 2 equipped with the sludge pump 13 is obliquely connected to the excavator's boom. When the supplementary cylinder 2 is close to the bottom of the reservoir, the huge suction force generated by the sludge pump 13 will cause the gravel above the sludge to enter the supplementary cylinder 2 first and be transported to the outside through the sludge pump 13. Subsequently, the plug plate 9 is obliquely inserted into the sludge and moves horizontally, so that the sludge enters the supplementary cylinder 2 and contacts the stirring rod 7. The motor 14 drives the stirring rod 7 to rotate, mixing the water and the sludge, turning the sludge into slurry and pumping it to the outside through the suction force of the sludge pump 13. While stirring, some long-strip garbage such as tree branches and tree trunks wrapped inside the sludge will contact the stirring rod 7 and be broken while stirring, preventing the long-strip garbage such as branches from causing pipeline blockage to the sludge pump 13.

[0020] In addition, while the supplementary cylinder 2 moves horizontally, the water pump 12 will also be started synchronously, continuously extracting the water resources on both sides of the supplementary cylinder 2 by using the inspection pipes 18 on both sides, thereby restricting the diffusion range of pollutants. At the same time, the absorbed water resources are injected into the supplementary cylinder 2 to enhance the stirring effect of the slurry.

[0021] Furthermore, two fitting grooves 26 are formed at the bottom of the additional cylinder 2. The first water pipe 10 and the second water pipe 25 are both fitted inside the fitting groove 26. The first water pipe 10 is located between the stirring rod 7 and the plug board 9. A drainage plate 6 is fixedly installed on the inner wall of the additional cylinder 2. The drainage plate 6 is located directly above the first water pipe 10. And one side of the first water pipe 10 close to the sludge pump 13 is of an arc structure. Multiple pipes are fitted inside a single fitting groove 26. And a plurality of through holes 24 are alternately formed at equal intervals above the inner wall of the fitting groove 26. The high-pressure nozzle 15 passes through the through hole 24 and extends into the additional cylinder 2.

[0022] Please refer to Figures 1-2 , during use, since the first water pipe 10 is located in front of the stirring rod 7, after the sludge enters the additional cylinder 2, it will first come into contact with the first water pipe 10. And the water resource pumped by the water pump 12 is injected into the first water pipe 10 through the connecting pipe 11, and the pumped water resource is injected into the additional cylinder 2 through the high-pressure nozzle 15 on the second water pipe 25. Then, the high-pressure water flow is used to impact the sludge entering the additional cylinder 2 to cut the sludge, facilitating the subsequent stirring by the stirring rod 7. At the same time, the arc-shaped drainage plate 6 above is used to guide the water flow to ensure that the water flow flows inside the additional cylinder 2, and a barrier is formed at the feeding port of the additional cylinder 2 by the water flow to reduce the possibility of pollutants diffusing out through the feeding port.

[0023] Furthermore, an inclined filter plate 8 is fixedly installed on the inner wall of the additional cylinder 2. The filter plate 8 is located between the stirring rod 7 and the sludge pump 13. The second water pipe 25 is located between the stirring rod 7 and the filter plate 8. A discharge port 5 is formed at the top of the additional cylinder 2. The discharge port 5 is located above the second water pipe 25. A U-shaped waste slot 19 is formed on the inner wall of the additional part 3. The waste slot 19 communicates with the additional cylinder 2 through the discharge port 5. Discharge ports 20 are symmetrically formed at the lower part of one side of the additional part 3 close to the sludge pump 13. A cover plate 17 is fitted inside the discharge port 20. The cover plate 17 is used to control the opening and closing of the discharge port 20. Two inclined guiding plates 4 are symmetrically installed at the top of the inner wall of the waste slot 19. The inclined guiding plates 4 are located directly above the discharge port 5. The spraying direction of the high-pressure nozzle 15 installed on the second water pipe 25 is horizontal with the filter plate 8.

[0024] Please refer to Figure 1 and Figure 4When in use, under the action of the sludge pump 13, the mud containing garbage will pass through the stirring rod 7 and move towards the direction of the sludge pump 13, and the installed filter plate 8 will be used to separate the solid and liquid of the mud. Some larger garbage will be blocked by the filter plate 8. At this time, the water resources extracted from both sides of the additional cylinder 2 by the water pump 12 will be sprayed out from the second water pipe 25 through the connecting pipe 11. The sprayed high-pressure water flow will reduce the water content and viscosity of the mud, and push the garbage covered on the filter plate 8 toward the discharge port 5, and then under the guidance of the inclined guide plate 4, it will be deposited on both sides of the inside of the waste tank 19, thereby completing the garbage filtering and preventing the garbage from combining with the sludge with high viscosity from clogging the sludge pump 13 or the pipeline.

[0025] After the silt removal is completed, the digging arm is adjusted to keep the additional cylinder 2 tilted, and the cover plate 17 is removed to open the discharge port 20, so that the garbage can slide out of the waste tank 19 from the discharge port 20.

[0026] Furthermore, a material storage trough 16 is provided inside the attachment 3 , and the material storage trough 16 is located next to the waste trough 19 , and the material storage trough 16 is located directly below the mounting trough 22 . A spreading hole 21 is provided at the bottom of the attachment 3 , and the spreading hole 21 is located directly below the material storage trough 16 .

[0027] Please refer to Figure 1 and Figure 3 Before dredging, some pre-treated aquatic grass seeds can be put into the storage tank 16 through the sowing hole 21. When in use, the vibration generated by the operation of the motor 14, the water pump 12 and the dredge pump 13 can be used to make the aquatic grass seeds gradually slide through the sowing hole 21 to the outside of the storage tank 16. Aquatic plants are sown while dredging, and the bottom of the water is repaired by aquatic plants to further reduce the impact of dredging on water quality.
