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

[0002] River dredging generally refers to the management of river channels. It is a water conservancy project. When cleaning a river channel, mechanical equipment is used to pump away the silt deposited on the riverbed, thereby clearing the water.

[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: In the current river dredging facilities, the pipes that extend into the river to extract silt often have large areas of debris such as plastic bags attached to them. If a blockage plate for the plastic bags is set up, the through holes on the blockage plate may be blocked by silt.

[0004] Therefore, we propose a dredging device for water conservancy projects to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a dredging device for water conservancy projects. The servo motor drives the cleaning rod and cleaning brush to rotate continuously on the interception plate, so that large areas of solid objects such as plastic bags attached to the interception plate can be removed. Two cylinders drive two sets of cleaning columns to pass through the through holes on the interception plate, so that the through holes of the interception plate will not be blocked, thereby greatly improving the dredging efficiency and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dredging device for water conservancy projects includes a diversion basin and a dredging mechanism located on the diversion basin. The dredging mechanism includes a dredging pump installed on one side wall of the diversion basin, a release pipe connected to the dredging pump, and a pipeline, wherein an absorption pipe is fixedly welded to the side of the pipeline facing away from the dredging pump.

[0008] An intercepting plate is welded to the side of the absorption pipe away from the pipe. The intercepting plate is circular and has several through holes for water and silt to pass through. The through holes are arranged in a neat manner. A boss is welded at the bend of the absorption pipe. A servo motor and two cylinders are installed on the boss, with the servo motor located between the two cylinders.

[0009] The output shaft of the servo motor is coaxially connected to a drive shaft, which passes through a through hole in the center of the interception disk and is connected to a cleaning rod. A cleaning brush that contacts the bottom wall of the interception disk is installed on the cleaning rod. A transmission rod is connected below the two cylinders, and an extension rod is welded to the bottom of the two transmission rods. A lifting plate is connected to the bottom of the two extension rods. Several cleaning columns are integrally welded to the bottom wall of each lifting plate, and the cleaning columns on the lifting plate are adapted to the through hole on the interception disk.

[0010] As a preferred embodiment, the inner cavity of the guide basin is provided with slopes on both sides, and a discharge port communicating with the inner cavity is opened on one side wall of the guide basin; so that the water and sludge drawn into the guide basin can be discharged from the discharge port, and the slope is used to make the water and sludge better collect at the center of the inner cavity of the guide basin.

[0011] As a preferred embodiment, the end of the release pipe away from the dredging pump extends into the inner cavity of the guide basin, and a support plate is welded to the end of the release pipe located in the inner cavity of the guide basin. The support plate is welded to the inner wall of the guide basin, thereby reinforcing the release pipe through the support plate.

[0012] As a preferred embodiment, the drive shaft is vertically installed inside the absorption tube, and the top end of the drive shaft is rotatably connected to the boss above the absorption tube; this allows the drive shaft to operate stably under the drive of the servo motor. The servo motor requires external power supply, and in actual applications, the servo motor cannot be immersed in water.

[0013] As a preferred embodiment, two bottom grooves are formed in the inner cavity of the absorption tube towards the protrusion, and two conveying rods are respectively installed in the two bottom grooves, so that the conveying rod structure remains stable.

[0014] As a preferred embodiment, both lifting plates are semi-circular, thus perfectly covering the cleaning work of the through holes on the circular plate-shaped interceptor plate.

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] This water conservancy project dredging device, while the dredging pump operates to extract silt from the river channel of the water conservancy project using the absorption pipe, simultaneously drives the servo motor to continuously rotate the cleaning rod and cleaning brush on the interception plate. This allows large areas of solid matter such as plastic bags attached to the interception plate to be removed. Two cylinders operate separately to drive two sets of cleaning columns to pass through the through holes on the interception plate, preventing the through holes from being blocked, thereby greatly improving the dredging efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A dredging device for water conservancy projects includes a guide basin 1 and a dredging mechanism located on the guide basin 1. Both sides of the inner cavity of the guide basin 1 are provided with slopes, and a discharge port 2 communicating with the inner cavity is opened on one side wall of the guide basin 1, so that the water and silt pumped into the guide basin 1 can be discharged from the discharge port 2. The slope is used to make the water and silt better collect at the center of the inner cavity of the guide basin 1.

[0025] The dredging mechanism includes a dredging pump 3 installed on one side wall of the diversion basin 1, a release pipe 4 connected to the dredging pump 3, and a pipe 5. The end of the release pipe 4 away from the dredging pump 3 extends into the inner cavity of the diversion basin 1, and a support plate is welded to the end of the release pipe 4 located in the inner cavity of the diversion basin 1. The support plate is welded to the inner wall of the diversion basin 1, thereby reinforcing the release pipe 4 through the support plate. An absorption pipe 6 is fixedly welded to the side of the pipe 5 facing away from the dredging pump 3.

[0026] An intercepting plate 7 is welded to the side of the absorption pipe 6 away from the pipe 5. The intercepting plate 7 is circular and has several through holes 8 for water and silt to pass through. The through holes 8 are arranged in a neat manner. A boss is welded at the bend of the absorption pipe 6. A servo motor 9 and two cylinders 13 are installed on the boss, with the servo motor 9 located between the two cylinders 13.

[0027] The output shaft of the servo motor 9 is coaxially connected to the drive shaft 10, and the drive shaft 10 passes through the through hole 8 at the center of the interception disk 7 and is connected to the cleaning rod 11. The drive shaft 10 is vertically installed inside the absorption tube 6, and the top end of the drive shaft 10 is rotatably connected to the boss above the absorption tube 6, so that the drive shaft 10 can operate stably under the drive of the servo motor 9. The servo motor 9 requires external power supply. In actual application, the servo motor 9 cannot be immersed in water. A cleaning brush 12 that contacts the bottom wall of the interception disk 7 is installed on the cleaning rod 11.

[0028] Below the two cylinders 13, there are two conveying rods 15 respectively. Two bottom grooves 14 are formed in the inner cavity of the absorption tube 6 facing the protrusion. The two conveying rods 15 are installed in the two bottom grooves 14 respectively, so that the structure of the conveying rods 15 remains stable. The bottom of the two conveying rods 15 is welded with extension rods 16. The bottom of the two extension rods 16 is connected with lifting plates 17 respectively. Several cleaning columns 18 are integrally welded on the bottom wall of each lifting plate 17. The cleaning columns 18 on the lifting plate 17 are all adapted to the through holes 8 on the interception plate 7. The two lifting plates 17 are semi-circular, so they can just cover the cleaning work of the through holes 8 on the circular plate-shaped interception plate 7.

[0029] This dredging device for water conservancy projects operates as follows: During use, the diversion basin 1 is kept horizontal and stable (e.g., fixed in a sturdy location on the riverbank of the water conservancy project). The dredging pump 3 is driven to extract water and silt from the river using pipes 5 and 6. The silt passes through multiple holes 8 on the interception plate 7 and enters the diversion basin 1 through pipes 5 and 4, eventually being discharged from the outlet 2. After continuous use, debris accumulates in the holes 8 of the interception plate 7. Larger debris, such as plastic bags, can be removed by driving the servo motor. When machine 9 is running, the drive shaft 10, cleaning rod 11, and cleaning brush 12 rotate to scrape and clean the bottom wall of intercepting plate 7. The silt attached to the through hole 8 can be removed by driving two cylinders 13 to operate separately. The cylinders 13 drive the conveyor rod 15, extension rod 16, and lifting plate 17 to sink, so that multiple cleaning columns 18 at the bottom of the lifting plate 17 insert into part of the through hole 8 on the intercepting plate 7, and automatically remove the silt in the through hole 8. However, the two cylinders 13 cannot work at the same time to avoid affecting the passage of water and silt in the through hole 8.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
