Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline cleaning, and in particular relates to a device for flushing pipeline sludge by utilizing water head pressure. Background Art

[0002] The urban drainage network buried below the ground is an indispensable and important infrastructure for modern cities. It is the backbone of urban water pollution prevention and control, urban drainage and flood control. With the extension of service time, due to various reasons such as construction quality problems during pipeline burial, heavy road transport vehicles, increased service life and inadequate management and maintenance of the pipeline network, the drainage pipeline will be damaged to varying degrees, which will bring troubles to urban drainage and ground transportation and communication. For the silt that is difficult to clean in the pipeline at the bottom of the foundation, the existing technology generally uses high-pressure water jets to dredge the inside of the pipeline. During operation, the high-pressure pump is driven by the car engine to pressurize the water and send it into the water jet nozzle. The reaction force generated by the backward spray makes the water jet nozzle and the hose move in the opposite direction, and also cleans the head wall at the same time. When the nozzle reaches the downstream inspection well, the motorized winch retracts the hose, and the water jet nozzle continues to spray water to flush the remaining sediment to the downstream inspection well, which is sucked away by the mud suction truck.

[0003] Among the existing patents, a Chinese patent with publication number CN209918497U discloses a high-pressure spray gun for a pipeline high-pressure cleaning vehicle. This prior art cleans the sludge on the inner wall of the pipeline while driving the spray nozzle forward by high pressure. However, the outer diameter of the spray nozzle in the device is smaller than the inner diameter of the pipeline. When the sharp part of the spray nozzle encounters harder impurities, the movement direction of the spray is easily offset, causing the direction of the water flow sprayed from the water jet head to change. During the cleaning process, when the water sprayed from the spray nozzle reaches the top of the pipeline, its water pressure may not be sufficient to clean the stubborn sludge on the top of the pipeline, which may also affect the flushing efficiency.

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a device for flushing sludge in pipes by utilizing water head pressure. The device for flushing sludge in pipes by utilizing water head pressure is provided with an inclined spray pipe. When high-pressure water is sprayed out, it can drive the high-pressure spray head to rotate and move, and can drive the roller brush to clean the inside of the pipe. In addition, the utility model is provided with an adjustment device, so that the roller brush can contact and cooperate with pipes of different diameters, which is easy to use.
