Problems solved by technology

Since the holes of the frame plate are designed to be circular, under the condition of satisfying the necessary hole spacing of the frame plate, its water permeability is not as high as the circumscribed regular hexagon of the original circular hole, so the original design did not make the water grate achieve the highest water permeability

Embodiment Construction

[0014] The urban sewer mosquito-killing water grate is made up of skeleton plate 1, support plate 2, plastic screw 3 and elastic cover sheet 4. The hole of the skeleton plate 1 is made into a regular hexagonal through hole, and the diameter of its circumscribed circle is consistent with the inner diameter of the mouth of the elastic cover sheet 4 to be installed. Expand a circular step at the bottom of the hole, the diameter of the step part is consistent with the diameter of the outer edge of the elastic cover sheet 4 to be installed, the circular step is concentric with the through hole of the frame plate 1, and its depth is the same as the elastic cover sheet 4 mouth Along the same thickness, the bottom of the skeleton plate 1 is provided with screw holes. The supporting plate 2 is a plastic plate with the same length and width as the frame plate 1 and a thickness of 3 mm. The number and distribution of round holes on the supporting plate 2 are the same as those of the fram...

Abstract

The present invention provides a kind of mosquito killing water grate for city sewer, and the mosquito killing water grate can cut off mosquito passage. The mosquito killing water grate is regular hexagonal orifice plate as the skeleton plate with elastic covering sheets between the skeleton plate and the backing plate. The present invention has excellent mosquito killing effect and rain water passing effect.

Description

1. Technical field [0001] The present invention relates to the design of an urban sewer mosquito-killing water grate, in particular an important improvement in the key technology of the application number 2005100224588, which is named "urban sewer mosquito-killing water grate". 2. Background technology [0002] The "urban sewer mosquito-killing water grate" that the applicant applied for on November 19, 2003 prevented mosquitoes from entering and leaving the water grate (patent number: ZL200310110986X), and the "urban sewer mosquito-killing water grate" applied for on December 30, 2005 "Water grate" (application number: ZL2005100224588) has made important improvements to the original structure, thereby cutting off the life chain of urban mosquitoes and achieving the goal of eliminating urban mosquitoes. But this invention still has the following major deficiencies in design: [0003] 1. Since the integral elastic cover is directly inserted into the hole of the skeleton plat...
