Urban sewer sterilization and deinsectization device

Abstract

The invention relates to the technical field of sewer sterilization, in particular to an urban sewer sterilization and deinsectization device. The urban sewer sterilization and deinsectization devicehas a treading type sterilization effect, is convenient to operate and comprises an outer sleeve, a pressing seat mechanism and a frame moving mechanism; four station grooves and four extending holesare formed in the top of the outer sleeve, a cylinder cavity is formed in the bottom of the outer sleeve, and the extending holes are in communication with the station grooves; an inner sleeve is embedded in the cylinder cavity of the outer sleeve, and the pressing seat mechanism is located at the top of the inner sleeve; a pressure bearing ring is arranged at the bottom of the inner sleeve, fourpenetrating holes are evenly formed in the pressure bearing ring, and the frame moving mechanism is arranged between the pressure bearing ring and the pressing seat mechanism through the penetrating holes; when the pressing seat mechanism is pressed down along the cylinder cavity of the outer sleeve, the frame moving mechanism is driven to be pressed down, when a user walks and treads spray bags in the environment in daily life, the pesticide injection effect on a sewer can be triggered, and the purpose of saving pesticide in a non-electric mode is achieved; and operation is convenient, and insect pests and germs in the sewer and the inner wall of the cylinder cavity of the device can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of sewer sterilization, in particular to an urban sewer sterilization device. Background technique [0002] According to a large-scale application, the sewer is a kind of urban public facility, which refers to the pipeline for removing sewage and rainwater from buildings; it also refers to the underground passage for discharging sewage and rainwater in cities, factories or villages, and is mostly used in small-scale applications. Similar to the bathroom drainage system, in actual use, it is often paired with the floor drain. During construction, the sewer is placed between the upper and lower floors, and the floor drain is located on the bathroom floor above the sewer. The used sewage is finally discharged down the sewer and is placed on top of the sewer for decorative protection. [0003] The protective floor drain used on the top of the bathroom sewer has a simple structure and poor functionality. For exa...

Problems solved by technology

[0003] The protective floor drain used on the top of the bathroom sewer has a simple structure and poor functionality. For example, during use, some pest species similar to cockroaches reach the bathroom through the drain hole of the floor drain. Therefore, we will soon find that as long as there is one household in the same unit If such pests are caused, all households will be affected. The main source of cockroaches is the sewer connected between two households. Therefore, it is necessary to design a sterilization and deinsectization device to solve this problem.
