Description

Technical Field

[0001] The utility model relates to the field of pipeline dredging, and particularly relates to a pipeline dredging device. Background Art

[0002] Pipeline dredging refers to dredging pipelines, cleaning the sludge and other wastes inside the pipelines, and keeping them unblocked for a long time to prevent urban waterlogging. If the pipelines are not dredged regularly, it will cause sewage overflow, pollute the environment, and bring trouble to people's lives.

[0003] Most of the existing pipeline dredging devices use nozzles connected to pipelines to spray high-pressure water flow into the pipelines, so that the high-pressure water flow can wash the sludge deposited in the pipelines, thereby achieving the dredging effect. Although such a dredging method can meet the conventional use requirements, when there are large stones or other heavy objects deposited in the pipelines, the cleaning effect of the nozzles spraying high-pressure water flow will be greatly reduced, and the large stones or other heavy objects cannot be taken out either. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a pipeline dredging device that can salvage larger objects in the pipeline and cooperate with high-pressure flushing by using a driving wheel as a power source according to the current situation of the prior art.

[0005] The utility model is realized through the following technical solutions: The utility model provides a pipeline dredging device, which includes a machine body. Installation grooves are respectively opened on both side walls of the machine body. Electric push rods are fixedly installed in the installation grooves. The electric push rods are symmetrically distributed. The fixed ends of the electric push rods are all connected to the machine body. The movable ends of the electric push rods are all fixedly installed with bearing seats. Motors are fixedly installed at the lower ends of the bearing seats. The transmission output ends of the motors are all key-connected with driving wheels. A carrying seat is fixedly installed in the middle of the lower end of the machine body.

A flushing block is fixedly installed on one side of the carrying seat at the lower end of the machine body. A connecting seat is inserted on one side wall of the flushing block.

[0006] By adopting the above technical solutions, the electric push rod can drive the driving wheel to expand to both sides by extending, so that it can be abutted against the inner wall of the pipeline, and the dredging grille and the dredging bar can be disassembled and replaced.

[0007] Furthermore, the transmission output end of the motor penetrates through the bearing seat and is connected through a bearing.

[0008] By adopting the above technical solutions, the power transmission of the motor is ensured to be stable.

[0011] Furthermore, the driving wheels are made of rubber, anti-slip patterns are arranged on the surfaces of the driving wheels, and the outer edges of the driving wheels are chamfered structures.

[0012] By adopting the above technical solutions, it is ensured that the power output of the driving wheels is stable, and the dredging device can be driven to displace stably in the pipeline.

[0013] Furthermore, the plug block is in an I-shaped structure.

[0014] By adopting the above technical solutions, it is ensured that the connection effect between the plug block and the carrying seat is stable.

[0015] Furthermore, one end of the fishing bar away from the fishing grille is sharp.

[0016] By adopting the above technical solutions, the fishing effect of the fishing bar on sundries is improved.

[0017] Furthermore, a flow splitting cavity is formed at the connection between the flushing block and the connecting seat. Pressing cavities are respectively formed at the lower ends of the flushing block in the flow splitting cavity. There are four pressing cavities and they are evenly distributed. Electric control valves are installed between the pressing cavities and the flow splitting cavity through clamping grooves. The number of the electric control valves matches the number of the pressing cavities.

[0018] By adopting the above technical solutions, the flushing block can split the externally supplied liquid, achieving different flushing effects.

[0019] Furthermore, spraying holes are respectively formed at the lower ends of the flushing block in the pressing cavities. The spraying holes are distributed in multiple groups. The aperture of each group of spraying holes gradually expands from the bottom to the side. The number of groups of the spraying holes matches the number of the pressing cavities.

[0020] By adopting the above technical solutions, the flushing block can select different flushing effects according to different requirements.

A carrying seat 7 is fixedly installed in the middle of the lower end of the body 1. An insertion block 8 is slidably connected in the carrying seat 7, enabling the insertion block 8 to be conveniently disassembled and assembled with the carrying seat 7. A fishing grid 9 is formed at the lower end of the insertion block 8. A fishing bar 10 is formed on one end wall of the fishing grid 9 to ensure the debris fishing effect of the fishing grid 9. A flushing block 11 is fixedly installed on one side of the carrying seat 7 at the lower end of the body 1. A connecting seat 12 is inserted into one side wall of the flushing block 11. The flushing block 11 can spray the water liquid supplied by the connecting seat 12 to achieve the flushing effect on the pipeline.

[0033] As Figures 1-3 shown, the driving output end of the motor 5 passes through the bearing seat 4 and is connected by a bearing to ensure the stable power transmission of the motor 5 to the driving wheel 6; the driving wheels 6 are symmetrically distributed, the driving wheels 6 are all set at a 45-degree angle, the driving wheels 6 are made of rubber material, anti-slip patterns are arranged on the surface of the driving wheels 6, and the outer edge of the driving wheels 6 is in a chamfer structure to ensure the stable driving effect of the driving wheels 6 on the dredging device.

[0034] As Figure 2 , Figure 4 and Figure 5 shown, the insertion block 8 has an I-shaped structure to ensure the stable connection effect between the insertion block 8 and the carrying seat 7; the end of the fishing bar 10 away from the fishing grid 9 is sharp to ensure the fishing effect of the fishing bar 10.

[0035] As Figure 2 and Figure 6As shown in the figure, a diversion cavity 13 is provided at the connection between the flushing block 11 and the connecting seat 12. At the lower end of the diversion cavity 13 in the flushing block 11, stamping cavities 14 are provided. There are four stamping cavities 14 and they are evenly distributed.
