Description

Technical Field

[0001] The utility model relates to the technical field of pollution cleaning machinery, in particular to a pollution cleaning lifting device with a new structure. Background Art

[0002] The three main types of sewage cleaning equipment currently used in hydropower stations are gantry grab bucket sewage cleaning machines, rotary sewage cleaning machines and inclined grab bucket sewage cleaning machines. The efficiency of the gantry grab bucket sewage cleaning machine is low when it is working, and a special grab bucket guide groove is required. In addition, due to the small gate groove, it is easy for sewage to accumulate in the gate groove. The efficiency and degree of automation of the rotary sewage cleaning machine are relatively high, but this type of sewage cleaning machine has poor cleaning effect on large sewage and is generally used in small power stations with little sewage. The trash rack of the inclined grab bucket sewage cleaning machine needs to be laid to the dam surface. The sewage unloading adopts a flap mechanism, which has high sewage cleaning efficiency and degree of automation, and is suitable for low-head power stations.

[0003] Timely and effective pollution cleaning of power stations is an important factor in ensuring the normal power generation of power station units and maintaining the stable operation of dams. Existing pollution cleaning solutions lack an efficient and reliable pollution cleaning solution for high-head dams when the trash rack and the garbage cleaning grab share the same gate slot. There is an urgent need for a new type of pollution cleaning equipment to solve the problem that in high-head power stations, the trash rack and the garbage cleaning grab share the same gate slot, and the trash rack is not deployed to the top of the dam. How to achieve the coordination between moving parts and between moving parts and trash racks during the cleaning process under the condition that the cleaning and garbage collection share the same gate slot is the focus and difficulty of the research and development of the lifting system of this new type of pollution cleaning device.

[0004] There is a patent for a sewage cleaning machine technology, for example, patent number CN201020565944.0, application date 2010.10.15, and utility model patent named "Mobile Grab Sewage Cleaning Machine", the technical solution of which is a mobile grab bucket sewage cleaning machine, including a traveling guide rail, a pulley device and a grab bucket device installed on the pulley device, characterized in that: the traveling guide rail is laid on the water intake dam that needs to be cleaned, the pulley device includes a pair of brackets and a crossbeam connecting the brackets, the grab bucket device is suspended and installed under the crossbeam, a pulley is installed at the bottom of the bracket, and the pulley is mounted on the traveling guide rail so that the pulley device can move parallel to the traveling guide rail.

[0005] Although the above patent can clean the dirt by using a mobile grab bucket, it requires a special travel guide rail to be set on the embankment. The pulley device can only move horizontally along the guide rail, and the grab bucket needs to be raised and lowered separately to realize the function of grabbing the dirt. Utility Model Content
