Energy-saving and environment-protecting device for self-preliminary clearing and blockage prevention of municipal sewage

Abstract

The invention relates to the technical field of sewage treatment, and discloses an energy-saving and environment-protecting device for self-preliminary clearing and blockage prevention of municipal sewage. The energy-saving and environment-protecting device comprises bearing covers, wherein drainage holes are formed in the middles of the bearing covers; connecting rods are movably connected to thebottoms of the bearing covers, transmission rods are movably connected to the bottoms of the connecting rods, and the bottoms of the transmission rods are movably connected with reset springs; and the right sides of the transmission rods are movably connected with rotating wheels, and the bottoms of the rotating wheels are movably connected with pull rods. The pull rods move in the vertical direction, supporting seats are pushed to squeeze clearing springs and deform the clearing springs, then one upward pushing force is applied to clearing seats, the pushing force is transmitted to clearingrods through the clearing seats and finally drives the clearing rods to do reciprocating motion in the vertical direction, and the clearing rods drag garbage blocked at the tops of the drainage holesinto the drainage holes in the reciprocating motion process, so that when the drainage holes of a sewer are blocked, automatic clearing is carried out, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an energy-saving and environment-friendly device for self-preliminary cleaning and anti-clogging of urban sewage. Background technique [0002] With the development of social economy and the increase of the global population, a large amount of sewage is produced in cities every day, and these sewage cannot be discharged directly into nature, otherwise it will affect the natural environment. Therefore, sewer pipes are installed in cities to collect Urban sewage is treated uniformly before being discharged into nature. [0003] In order to prevent pedestrians from entering by mistake, urban sewers are equipped with manhole covers to collect urban sewage while not disturbing people's normal walking. However, urban sewage often contains a large amount of solids such as branches, leaves, plastic bags, etc., which are very easy to block the manhole cover. The water inlet hole...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an energy-saving and environment-friendly device for self-preliminary cleaning and anti-clogging of urban sewage, which is equipped with automatic cleaning to improve sewage treatment efficiency when sewer drain holes are blocked, and automatic spraying of air purifiers to prevent sewage in the sewer The bad smell affects people's life advantages, and solves the problem that when the traditional manhole cover is blocked, the blockage cannot be effectively cleaned, and the odor in the sewer is often emitted from the manhole cover
