Description

Technical Field

[0001] This utility model relates to the field of municipal cleaning technology, and in particular to a high-pressure flushing rainwater grate cleaning vehicle. Background Technology

[0002] A storm drain grate is a municipal drainage system component installed above ground drain outlets. It is mainly used to collect rainwater from the ground and guide it into underground drainage pipes. At the same time, it filters larger debris such as leaves and garbage through regularly arranged holes on its surface to prevent pipe blockage. It is mostly a plate-like structure and is made of materials such as cast iron, steel grating, stainless steel, composite materials, and concrete. It is generally embedded in the ground, with its edges flush with or slightly lower than the ground. Together with drainage pipes and inspection wells, it forms a complete drainage system, playing a role in drainage, flood prevention, and pipe protection.

[0003] Currently, the cleaning of storm drain grates mainly relies on high-pressure washing by cleaning trucks. However, existing cleaning equipment has significant functional defects. Its washing mechanism lacks multi-dimensional angle adjustment capabilities, resulting in a fixed and singular spray angle of high-pressure water. This makes it impossible to dynamically adjust the washing direction according to the grate's structural characteristics and the degree of dirt adhesion, severely limiting cleaning efficiency and effectiveness. This technological limitation makes it difficult to completely remove stubborn deposits, not only wasting water resources but also potentially leading to repeated washing failing to achieve the desired cleaning standards. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure flushing rainwater grate cleaning vehicle to address the significant functional deficiencies of existing cleaning equipment mentioned in the background section. These devices lack multi-dimensional angle adjustment capabilities in their flushing mechanisms, resulting in a fixed and singular spray angle of the high-pressure water stream. This prevents dynamic adjustment of the flushing direction based on the grate's structural characteristics and the extent of dirt adhesion, severely limiting cleaning efficiency and effectiveness. This technological limitation makes it difficult to thoroughly remove stubborn deposits, not only wasting water resources but also potentially leading to repeated flushing failing to achieve the desired cleaning standards.
