Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a dredging device for water conservancy projects. Background Technology

[0002] Hydraulic engineering dredging equipment is a specialized device used to remove silt and debris from water conservancy facilities (such as rivers, reservoirs, and ports), ensuring the normal operation of water conservancy projects and the smooth flow of waterways. Its working principle is typically based on different technologies. For example, the common cutter suction dredging device uses a rotating cutter installed at the bow or front of the hull to chop up the silt at the bottom of the water. Then, a centrifugal pump generates strong suction to draw the slurry formed by the mixture of chopped silt and water into a designated area through pipelines. Another type is the rake suction dredging device, where a ship-mounted rake head sinks to the bottom to loosen the silt, and then a vacuum pump on board draws it up to collect and transfer the silt.

[0003] For example, Chinese Patent Publication No. CN222206537U discloses a dredging device for water conservancy projects, including a vehicle body, a shock-absorbing component on the top of the vehicle body, a sewage suction pump on the top of the shock-absorbing component, an inlet hose connected to the input end of the sewage suction pump, and a fixing frame on the top of the vehicle body.

[0004] When cleaning up silt and sewage in water channels, floating debris such as plastic bags in the sewage is easily sucked into the silt conduit by the centrifugal pump, causing blockage and hindering the continuity of the dredging work. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that when cleaning silt and sewage in water channels, plastic bags in the sewage are easily sucked into the silt conduit by the suction of the centrifugal pump, which leads to blockage of the silt conduit. Therefore, this invention proposes a silt removal device for water conservancy projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dredging device for water conservancy projects, comprising a centrifugal pump and a sludge conduit, wherein the input end of the centrifugal pump is fixedly connected to the output end of the sludge conduit, and a debris isolator is fixedly connected to the outside of the input end of the sludge conduit, wherein the debris isolator comprises an installation plate, a connecting plate and an isolation rod, wherein the two ends of several connecting plates and isolation rods are respectively fixedly connected between two installation plates, and one installation plate is fixedly connected to the outside of the sludge conduit, and a debris pushing ring is slidably connected to the outside of the debris isolator.

[0007] Preferably, a plurality of debris pushing plates are fixedly connected to the inner side of the debris pushing ring in a ring arrangement, and the debris pushing plates are disposed between two isolation rods.

[0008] Preferably, the connecting plate has a sliding groove inside.

[0009] Preferably, a plurality of sliding blocks are fixedly connected to the inner side of the debris pushing ring in a ring arrangement, and the sliding blocks are slidably engaged inside the sliding groove.

[0010] Preferably, a drive rod is fixedly connected to both ends of the debris pushing ring, and a pressure plate is fixedly connected to the other end of the drive rod.

[0011] Preferably, a limiting plate is fixedly connected to the middle of the sludge guide tube, and the other ends of the two drive rods respectively movably pass through both ends of the limiting plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by starting the centrifugal pump, the sludge located at the inlet of the sludge conduit is affected by the suction of the centrifugal pump and enters the interior of the sludge conduit through the debris separator. Meanwhile, floating garbage such as plastic bags in the sludge and sewage is blocked on the outside of the connecting plate and the isolation rod, so that floating garbage such as plastic bags cannot enter the interior of the sludge conduit, ensuring that the dredging work can continue and avoiding the problem of sludge conduit blockage.

[0014] 2. In this invention, by manipulating the other end of the drive rod above the water surface to make it move up and down rhythmically, the drive rod will cause the connected debris pushing ring to move up and down synchronously on the outside of the debris separator. As the debris pushing ring continues to operate, its attached debris pushing plate can gradually push the accumulated floating garbage such as plastic bags to the lower end of the debris separator. The silt smoothly enters the silt conduit through the gap reserved between the connecting plate and the separator rod, effectively avoiding the blockage problem caused by the accumulation of floating garbage, and further ensuring the continuity and sustainability of the dredging work.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a dredging device for water conservancy projects, including a centrifugal pump and a sludge conduit 1. The input end of the centrifugal pump is fixedly connected to the output end of the sludge conduit 1. A debris isolator 2 is fixedly connected to the outside of the input end of the sludge conduit 1. The debris isolator 2 includes a mounting plate 21, a connecting plate 22, and an isolation rod 23. The two ends of several connecting plates 22 and isolation rods 23 are respectively fixedly connected between two mounting plates 21. One mounting plate 21 is fixedly connected to the outside of the sludge conduit 1. A debris pushing ring 3 is slidably connected to the outside of the debris isolator 2.

[0023] The specific setup and function of this embodiment are described below. The debris isolator 2 is fixedly installed on the outside of the inlet end of the sludge conduit 1. Then, the centrifugal pump is started. The sludge at the inlet end of the sludge conduit 1 is affected by the suction of the centrifugal pump and enters the interior of the sludge conduit 1 through the debris isolator 2. Meanwhile, floating debris such as plastic bags in the sludge and sewage is blocked on the outside of the connecting plate 22 and the isolation rod 23, so that floating debris such as plastic bags cannot enter the interior of the sludge conduit 1, ensuring that the dredging work can continue and avoiding the problem of blockage of the sludge conduit 1.

[0024] Example 2: Figure 1 - Figure 4As shown, a dredging device for water conservancy projects includes a centrifugal pump and a sludge conduit 1. The input end of the centrifugal pump is fixedly connected to the output end of the sludge conduit 1. A debris isolator 2 is fixedly connected to the outside of the input end of the sludge conduit 1. The debris isolator 2 includes a mounting plate 21, a connecting plate 22, and an isolation rod 23. The two ends of several connecting plates 22 and isolation rods 23 are respectively fixedly connected between two mounting plates 21. One mounting plate 21 is fixedly connected to the outside of the sludge conduit 1. A debris pushing ring 3 is slidably connected to the outside of the debris isolator 2. The inner side of the debris pushing ring 3 is fixed in a ring arrangement. Several debris-pushing plates 31 are connected, and the debris-pushing plates 31 are set between two isolation rods 23. A sliding groove 221 is opened inside the connecting plate 22. Several sliding blocks 32 are fixedly connected in a ring arrangement on the inner side of the debris-pushing ring 3. The sliding blocks 32 are slidably engaged in the sliding groove 221. Drive rods 33 are fixedly connected to both ends of the debris-pushing ring 3. A pressure plate 331 is fixedly connected to the other end of the drive rod 33. A limit plate 11 is fixedly connected to the middle of the sludge guide 1. The other ends of the two drive rods 33 are respectively movably inserted through both ends of the limit plate 11.

[0025] The overall effect of this embodiment is that, during the dredging process of a water conservancy project, when floating debris such as plastic bags accumulates on the outside of the connecting plate 22 and the isolation rod 23, thus obstructing the smooth entry of silt into the silt conduit 1, on-site workers need to use a professional lifting and driving tool to operate the other end of the driving rod 33 from above the water surface, causing it to move up and down rhythmically. During this process, the driving rod 33 drives the connected debris pushing ring 3 to move up and down synchronously on the outside of the debris isolator 2. As the debris pushing ring 3 continues to operate, its attached debris pushing plate 31 can gradually push the accumulated floating debris such as plastic bags to the lower end of the debris isolator 2. In this way, the silt can smoothly enter the silt conduit 1 through the gap reserved between the connecting plate 22 and the isolation rod 23, effectively avoiding the blockage problem caused by the accumulation of floating debris, further ensuring the continuity and sustainability of the dredging work, and ensuring the steady progress of the entire water conservancy dredging project.

[0026] The method of use and working principle of this device: The debris separator 2 is fixedly installed on the outside of the inlet end of the sludge conduit 1. Then, the centrifugal pump is started. The sludge at the inlet end of the sludge conduit 1 is affected by the suction of the centrifugal pump and enters the interior of the sludge conduit 1 through the debris separator 2. Meanwhile, floating garbage such as plastic bags in the sludge and sewage is blocked on the outside of the connecting plate 22 and the isolation rod 23, so that floating garbage such as plastic bags cannot enter the interior of the sludge conduit 1, ensuring that the dredging work can continue.

[0027] During the dredging operation of a water conservancy project, when floating debris such as plastic bags accumulates on the outside of the connecting plate 22 and the isolation rod 23, thus obstructing the smooth entry of silt into the silt conduit 1, on-site workers need to use a specialized lifting and driving tool to operate the other end of the driving rod 33 from above the water surface, causing it to move up and down rhythmically. During this process, the driving rod 33 drives the connected debris pushing ring 3 to move up and down synchronously on the outside of the debris isolator 2. As the debris pushing ring 3 continues to operate, its attached debris pushing plate 31 can gradually push the accumulated floating debris such as plastic bags to the lower end of the debris isolator 2. In this way, the silt can smoothly enter the silt conduit 1 through the gap reserved between the connecting plate 22 and the isolation rod 23, effectively avoiding the blockage problem caused by the accumulation of floating debris.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
