Description

Technical Field

[0001] The utility model relates to the technical field of silt clearing devices, and more specifically to a silt clearing device for a water conservancy project. Background Art

[0002] In the field of pipeline maintenance and cleaning, pipeline siltation is a common and important problem. Sedimentation in the pipeline, such as sludge, grease, etc., not only affects the normal operation of the pipeline, but may also cause pipeline blockage and cause serious drainage problems. Therefore, the development of an efficient and flexible pipeline cleaning device is crucial to ensure the normal operation of the pipeline system.

[0003] The Chinese patent authorization announcement number: CN216948702U provides an efficient dredging device for water conservancy engineering pipelines. By rotating the rotating motor, the No. 1 support rod can drive the scraper to continuously rotate in contact with the inner wall of the pipeline body, so that the mud blocks adhered to the inner wall of the pipeline body are scraped off, which is convenient for the staff to use the water pipe to flush the mud blocks inside the pipeline body, making the dredging effect inside the pipeline body more efficient. The threaded drill bit rotates synchronously with the No. 2 support rod, which is convenient for breaking the larger mud blocks blocked inside the pipeline body; traditional pipeline cleaning methods, such as using dredging tools such as "water rats", can solve the problem of pipeline siltation to a certain extent, but there are many limitations. These tools usually require an external water source during the cleaning process, which increases the complexity and cost of the operation. In addition, these tools also have certain limitations in cleaning effect, and it is difficult to completely remove the silt in the pipeline.

[0004] Therefore, a water conservancy project silt removal device is proposed in response to the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a dredging device for water conservancy projects, which can generate a propulsion force through a propeller to enable the device to move freely in the pipeline, and at the same time use the powerful impact force generated by a high-pressure water gun to impact and disintegrate the silt in the pipeline.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A dredging device for a water conservancy project comprises a shell and a high-pressure water gun, wherein an annular slide rail is fixedly mounted on the outer wall of the shell near the left and right ends, an electric slide rail is slidably mounted on the upper and lower ends of the annular slide rail, an electric push rod is fixedly mounted on the upper end of the electric slide near the front and rear sides, a roller assembly is fixedly connected between the upper output ends of the electric push rod, a fixing sleeve is fixedly mounted on the outer wall of the high-pressure water gun near the left and right sides, an ear plate is fixedly connected to the middle of the upper end of the fixing sleeve on the right side, an adapter is fixedly connected to the middle of the lower end of the roller assembly on the upper right side, the ear plate and the adapter are rotatably connected, and a water suction pipe is fixedly mounted on the left end of the high-pressure water gun.

[0010] Furthermore, a rotating member is fixedly connected to the middle position of the front and rear ends of the fixed sleeve on the left side, and the front and rear ends of the fixed sleeve on the left side are rotationally connected to the cylinders of the two sets of electric push rods through the rotating member.

[0011] Furthermore, a propeller is provided at the left end of the shell, a gap exists between the left end of the water extraction pipe and the blades of the propeller, and a cleaning motor is fixedly installed at the middle position inside the shell.

[0012] Furthermore, a cleaning motor is fixedly installed inside the shell near the right side, and a turntable is fixedly installed at the right output end of the cleaning motor passing through the shell.

[0013] Furthermore, the outer ring of the turntable is fixedly connected with twelve groups of trapezoidal members arranged in a circular array, and the higher ends of the trapezoidal members are all inclinedly provided with fixed cavities.

[0014] Furthermore, an elastic member is fixedly installed inside the fixing cavity by means of bolts, and metal bristles are arranged at one end of the elastic member facing outwards.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) Turning on the electric push rod can make the roller assembly stop when it hits the pipe wall, thereby fixing the device to prevent shaking from affecting the dredging operation. During this process, the roller assembly on the upper right side will drive the nozzle of the high-pressure water gun to rise through the ear plate and the adapter when it rises, so that the nozzle of the high-pressure water gun is inclined and aimed at the front pipe wall. Since there is an existing water source in the pipeline, the high-pressure water gun can be turned on to directly impact the silt attached to the pipe wall, and the impact force of the water flow can be used to disintegrate the silt. Compared with the current "water rat" pipeline dredging structure, this device is not restricted by water pipes and can use water resources on site, making it more flexible to use.

[0018] (2) By turning on the cleaning motor, the elastic part can be driven to rotate, so that the metal bristles can clean the pipe wall and sludge. The elastic part has a certain elasticity, which makes the elastic part and the metal bristles adaptive. When they come into contact with the pipe wall and sludge, they can automatically adjust, thereby improving the brushing effect and avoiding damage to the structure caused by the reaction force when it is resisted. In addition, the water flow sprayed by the high-pressure water gun can also rinse the rotating metal bristles to keep them clean. The structure is simple and the design is ingenious.

[0027] Example:

[0028] See also Figure 1-3 A desilting device for a water conservancy project comprises a shell 1 and a high-pressure water gun 6. The outer wall of the shell 1 is fixedly installed with annular slide rails 2 near the left and right ends. The annular slide rails 2 are slidably installed with electric sliders 3 at the upper and lower ends. The upper end of the electric slider 3 is fixedly installed with electric push rods 4 near the front and rear sides. The upper output ends of the electric push rods 4 are fixedly connected with roller assemblies 5. The outer wall of the high-pressure water gun 6 is fixedly installed with fixed sleeves 7 near the left and right sides. The middle of the upper end of the right fixed sleeve 7 is fixedly connected with an ear plate 9. The middle of the lower end of the right upper roller assembly 5 is fixedly connected with an adapter 10. The ear plate 9 and the adapter 10 are rotatably connected. The left end of the high-pressure water gun 6 is fixedly installed with a water pumping pipe 11.

[0029] When the shell 1 moves to the appropriate position, the propeller 12 is turned off and the electric push rod 4 is turned on to drive the roller assembly 5 to output, until the roller assembly 5 stops when it contacts the pipe wall, thereby fixing the device to prevent shaking from affecting the dredging operation. During this process, the roller assembly 5 at the upper right end will drive the nozzle of the high-pressure water gun 6 to rise through the ear plate 9 and the adapter 10 when it rises. At this time, the nozzle of the high-pressure water gun 6 is at an inclined angle, just aimed at the front pipe wall. Since there is an existing water source in the pipeline, the high-pressure water gun 6 can be turned on to directly impact the silt attached to the pipe wall, and the impact force of the water flow can be used to disintegrate and collapse the silt. Compared with the current "water rat" pipeline dredging structure, this device is not restricted by water pipes, and can use water resources on site, which is more flexible when used.

[0030] See also Figure 3 The middle positions of the front and rear ends of the left fixed sleeve 7 are fixedly connected with rotating parts 8, and the front and rear ends of the left fixed sleeve 7 are rotatably connected with the cylinder barrels of the two sets of electric push rods 4 through the rotating parts 8;

[0031] The rear end of the high-pressure water gun 6 is positioned by the rotating member 8 without affecting its rotation, thus ensuring the rationality of the structure.

[0032] See also Figure 3A propeller 12 is disposed at the left end of the housing 1, a gap exists between the left end of the water pumping pipe 11 and the blades of the propeller 12, and a remote control component 13 is fixedly installed at the middle position inside the housing 1;

[0033] The device is pushed forward by the water flow in the pipe after starting the propeller 12. The staff can install a camera on the shell 1 for remote control. When the returned image shows that there is siltation ahead, a signal instruction is sent to the remote control component 13.

[0034] See also Figure 1-2 A cleaning motor 14 is fixedly installed near the right side of the housing 1. A turntable 15 is fixedly installed at the right output end of the cleaning motor 14 through the housing 1. The outer ring of the turntable 15 is fixedly connected with twelve groups of trapezoidal members 16 arranged in a circular array. The higher end of the trapezoidal members 16 is obliquely provided with a fixing cavity 17. The inside of the fixing cavity 17 is fixedly installed with an elastic member 18 by bolts. The elastic member 18 is provided with metal bristles 19 at the end facing outward;

[0035] By turning on the cleaning motor 14, the turntable 15 can be driven to rotate, and the rotation of the turntable 15 can drive the elastic member 18 to rotate, so that the metal bristles 19 can clean the pipe wall and sludge. The elastic member 18 has a certain elasticity, so that the elastic member 18 and the metal bristles 19 have adaptive characteristics. They can automatically adjust when in contact with the pipe wall and sludge, thereby improving the brushing effect and avoiding damage to the structure caused by reaction force when being resisted. In addition, the water flow sprayed by the high-pressure water gun 6 can also rinse the rotating metal bristles 19 to keep it clean. The structure is simple and the design is ingenious.

[0036] Working principle: This device is pushed forward by the water flow in the pipe after starting the propeller 12. The staff can install a camera on the shell 1 for remote control. When the transmitted image shows that there is siltation in front, a signal command is sent to the remote control component 13. When the shell 1 moves to a suitable position, the propeller 12 is turned off and the electric push rod 4 is turned on to drive the roller assembly 5 to output until the roller assembly 5 stops when it contacts the pipe wall, thereby fixing the device to prevent shaking from affecting the dredging operation. During this process, the roller assembly 5 at the upper right end will drive the nozzle of the high-pressure water gun 6 to rise through the ear plate 9 and the adapter 10 when it rises, and the rear end of the high-pressure water gun 6 is positioned by the rotating member 8 without affecting its rotation. At this time, the nozzle of the high-pressure water gun 6 is at an inclined angle, just aimed at the front pipe wall. Since there is an existing water source in the pipe, the high-pressure water gun 6 can be turned on. Directly impact the silt attached to the pipe wall, and use the impact force of the water flow to disintegrate the silt. Compared with the current "water rat" pipeline dredging structure, this device is not restricted by water pipes and can use water resources on site, which is more flexible to use. Furthermore, by turning on the cleaning motor 14, the turntable 15 can be driven to rotate, and the rotation of the turntable 15 can drive the elastic member 18 to rotate, so that the metal bristles 19 can clean the pipe wall and silt. The elastic member 18 has a certain elasticity, so that the elastic member 18 and the metal bristles 19 have adaptive characteristics, and can automatically adjust when in contact with the pipe wall and silt, thereby improving the brushing effect and avoiding damage to the structure due to reaction force when being resisted. In addition, the water flow sprayed by the high-pressure water gun 6 can also rinse the rotating metal bristles 19 to keep it clean. The structure is simple and the design is ingenious.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
