Description

Technical Field

[0001] This utility model relates to the field of cleaning vehicles, specifically to a full-diameter urban drainage pipeline cleaning vehicle. Background Technology

[0002] Cleaning trucks are professional maintenance vehicles used for cleaning and dredging urban drainage pipes. The products mainly include two functions: primary cleaning and secondary cleaning. Urban drainage pipes typically have a diameter of φ100~1000mm. The primary cleaning function of traditional cleaning trucks is suitable for dredging drainage pipes with a diameter of φ200~1000mm, mainly including large-diameter drainage pipes such as municipal pipe networks. However, the secondary cleaning function, due to the chassis operating at idle or low speed, results in a low-pressure water pump with a low water pressure of only 1~2MPa, limiting it to routine conditions such as cleaning floors and vehicle bodies. Furthermore, the speed is automatically controlled electrically; if the electrical control malfunctions, there is a risk of overpressure during secondary cleaning.

[0003] Traditional cleaning trucks are not suitable for small-diameter drainage pipes with a diameter of φ100~200mm. However, there are a large number of small-diameter drainage pipes with a diameter of φ100~200mm in the community drainage network. Therefore, traditional cleaning trucks are not very adaptable to the working conditions of various pipe diameters in urban drainage pipes.

[0004] Therefore, a cleaning vehicle is needed that can adapt to cleaning drainage pipes of various diameters in cities. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a full-diameter urban drainage pipeline cleaning vehicle. This cleaning vehicle can clean both large-diameter and small-diameter pipelines in urban areas.

[0006] The purpose of this utility model is achieved by the following solution: a full-diameter working condition urban drainage pipeline cleaning vehicle, including a cleaning vehicle body, the front end of the cleaning vehicle body is the vehicle head, a water storage tank is set above the rear end of the cleaning vehicle body, a high-pressure water pump and a control valve are set between the water storage tank and the vehicle head, a high-pressure main reel is set at the rear end of the water storage tank, a low-pressure auxiliary reel is set on the side of the rear end of the water storage tank, the inlet of the high-pressure water pump is connected to the outlet of the water storage tank through a pipeline, the outlet of the high-pressure water pump is connected to the inlet of the flow meter through a pipeline, the outlet of the flow meter is connected to the middle position of the first pneumatic three-way ball valve through a pipeline, the right position of the first pneumatic three-way ball valve is connected to the high-pressure main reel through a pipeline to form a main cleaning pipeline, the left position of the first pneumatic three-way ball valve is connected to the middle position of the second pneumatic three-way ball valve through a pipeline, the right position of the second pneumatic three-way ball valve is connected to the inlet of the unloading valve through a pipeline, and the outlet of the unloading valve is connected to the low-pressure auxiliary reel through a pipeline to form a secondary cleaning pipeline.

[0007] The left position of the second pneumatic three-way ball valve is connected to the return port of the water storage tank through a pipeline.

[0008] The outlet of the high-pressure water pump is connected to the inlet of the safety valve via a pipe, and the outlet of the safety valve is connected to the return outlet of the water storage tank via a pipe.

[0009] The unloading valve is a mechanical unloading valve.

[0010] The advantages of this utility model are: 1) It can clean and dredge small-diameter drainage pipes with a diameter of φ100~200;

[0011] 2) The auxiliary cleaning pipeline is equipped with a mechanical unloading valve to avoid the risk of overpressure in the auxiliary cleaning process due to electrical control abnormalities or human error.

[0012] 3) Two pneumatic three-way ball valves switch between main and auxiliary cleaning, which greatly automates the process, reduces labor intensity, and improves cleaning efficiency. Attached Figure Description
