Mosquito eradication grid for urban sewer

Abstract

The mosquito disaster problems in city can never be solved. The reason lies in that the spidery sewer under the ground in city provides wide and ideal places for mosquito breeding; besides, a large number of shutter grates on two sides of roads in city and around the buildings provide a convenient gate for mosquito entering / leaving the sewer. The invention provides a shutter grate used for the sewer in city and able to kill mosquito, composed of round-hole frame board and elastic cover piece, where the top of the elastic cover piece tightly adheres to the hole wall, the bottom is arranged with uniform elastic fine strips to compose a closed curve, the water, mud and rubbish can all smoothly pass through the curve downwards, but the mosquito can not pass through it, and because the lift chain is cut-off, it achieves the purpose of thoroughly eliminate the mosquito disaster in city.

Description

1. Technical field [0001] The invention belongs to the technical field of manufacturing urban sewer fittings, and relates to an urban sewer mosquito-killing water grate capable of eradicating urban mosquito damage. 2. Technical Background [0002] As we all know, the breeding of mosquitoes is inseparable from stinky puddles. For modern cities, stinky puddles cannot be seen at all. So where do a large number of mosquitoes come from? Without careful observation, it is difficult for people to realize that the sewers under a large number of water grates on both sides of urban roads and around buildings provide a wide and ideal place for mosquitoes to breed, and these water grates are the breeding grounds for mosquitoes. It provides a convenient door for the entry and exit of the water grate. If the pores of the water grate are made into a gauze structure, although the purpose of preventing mosquitoes can be achieved, the small holes of the gauze will be lost due to the clogging ...

[0002] As we all know, the breeding of mosquitoes is inseparable from stinky puddles. For modern cities, stinky puddles cannot be seen at all. So where do a large number of mosquitoes come from? Without careful observation, it is difficult for people to realize that the sewers under a large number of water grates on both sides of urban roads and around buildings provide a wide and ideal place for mosquitoes to breed, and these water grates are the breeding grounds for mosquitoes. It provides a convenient door for the entry and exit of the water grate. If the pores of the water grate are made into a gauze structure, although the purpose of preventing mosquitoes can be achieved, the small holes of the gauze will be lost due to the clogging of garbage and sand if the time is a little longer. The function of passing water, so the gap width of the known water grates is controlled at 2-3 cm, but this width is a very spacious door for mosquitoes
