Abstract
Because a plurality of sewage channels under the urban ground provide wide ideal places for mosquito multiplication, the mosquito disaster problem in cities is always not eliminated, while a plurality of water grates at both sides of an urban road and the circumference of a building provide convenient gates for mosquitoes entering and exiting the sewage channels. The present invention provides a mosquito killing water grate of urban sewage channels, which is composed of a framework plate in a circular hole shape of the water grate and an elastic cover sheet, wherein the upper part of the elastic cover sheet is tightly attached to the hole wall, and the upper part is a closed curved surface composed of elastic thin strips which are uniformly arranged. Water, silt and refuse can easily pass through the curved surface downwards, but the mosquitoes can not pass through the curved surface. Because the life chain of the mosquitoes is broken, thereby, the purpose of the thorough elimination of the urban mosquito disaster is achieved.
Description
One, technical field
The invention belongs to municipal sewage system accessory manufacturing technology field, is a kind of mosquito-eradicating water grate for urban sewer that can eradicate the city anaphelism.
Two, technical background
As everyone knows, the procreation of mosquito be unable to do without cesspool, for modern city, can't see cesspool at all, what so a large amount of mosquitoes come actually from? if without examining, people are difficult to recognize: the sewer below drain covers a large amount of around the both sides of urban road and the building, for the procreation of mosquito provides son wide and desirable place, these drain covers then provide convenience for the turnover of mosquito, if the hole of drain cover is made the gauze structure, though can reach mosquito-proof purpose, but the time is long slightly, and the tiny eyelet of gauze will be because of rubbish, the obstruction of silt and lost the function of water is so the gap width of present known drain cover all is controlled at 2-3 centimetre, yet this width but is very spacious together gate for mosquito.
Three, summary of the invention
The purpose of this invention is to provide a kind of can kill mosquito, the mosquito-eradicating water grate for urban sewer that can not cause the drain cover eyelet to stop up again.
The objective of the invention is to be achieved through the following technical solutions:
Circular clear opening or the up big and down small tip circle conical through-hole that goes are done in the hole of drain cover frame board, a step is expanded on top in the hole, the diameter of step part is consistent with the diameter of the elastic covering sheet oral area outer that will install, the degree of depth then with the consistency of thickness of elastic covering sheet.The diameter in hole is controlled between the 20-70 millimeter.The elastic covering sheet can have two kinds of form of structure, a kind of is monolithic, another kind is an expandable type, and monolithic top is straight cylinder, and oral area has an outside horizontal bending, this bending part constitutes an annular plane, its underpart is evenly distributed, lateral dimension less than 8 millimeters slice, and these slices all bend towards inboard center, and the end of slice is interlaced, constitute closed surface, this monolithic elastic covering sheet can directly insert in the hole of drain cover frame board; There is a bending of 90 degree the developed surface upper end of expandable type, its bending part has uniform, vertical with developed surface at interval otch, the top of developed surface is a plane, the bottom is arranged in a uniform, lateral dimension less than 8 millimeters slice, these slices have two kinds of situations, a kind of is the vertical bar formula, and another kind is curved bar formula, and all the direction with the bending of elastic covering sheet oral area is opposite for the curved direction of curved bar in the curved bar formula.Expandable type elastic covering sheet is behind the hole of curling and insertion drain cover frame board, the top of elastic covering sheet is in automatic expansion of moment and be close to hole wall, the then interlaced formation closed surface in the slice end of its underpart, wherein vertical bar formula elastic covering sheet must match with the drain cover frame board of band taper hole.The thickness of the slice of elastic covering sheet is between the 0.1-0.6 millimeter, and the interval between adjacent two slices is less than 2 millimeters.The constituent material of elastic covering sheet is plastics, metal or bamboo.
Because the slice that constitutes elastic covering sheet closed surface not only carefully but also thin, so its unable current, silt and rubbish that stops from the top, for these materials, this closed surface is an automatic unilateral gate.Tiny current can pass from the slit between cover sheet slice, the slice that big current can make the cover sheet to around open the formation clear opening, silt and rubbish then belong to transients by the elastic covering sheet, so in these three kinds of situations, all do not have the chance that mosquito is passed through.
After adopting technique scheme, can receive following remarkable result:
1, because both having blocked the female mosquito that grows up, the closed surface that the elastic covering sheet constitutes entered the passage that sewer is laid eggs, blocked the passage that the new mosquito that has just hatched gets out ground again simultaneously, in fact this cut off the life chain of mosquito, thereby can thoroughly eradicate the invasion of city mosquito in a short time.
2, this kill mosquito method is compared with the medicine kill mosquito, and it not only thoroughly but also can receive the remarkable environmental effect.
3, because the manufacture craft of drain cover frame board only is to make the strip hole into circular port, therefore not only can not increase the manufacture difficulty and the manufacturing cost of plank, adopt circular eyelet also can eliminate the internal stress of strip eyelet greatly, thereby improved the intensity of plank, and can save the materials of plank.
4, each less than of elastic covering sheet materials 50 grams, and can realize that mechanization produces continuously, cost is extremely low.
5, the installation of elastic covering sheet is changed very easyly, and need not any instrument.
Four, description of drawings
The invention will be further described for the contrast drawings and Examples below:
Fig. 1 (A) is the front view of mosquito-eradicating water grate for urban sewer, and Fig. 1 (B) is its vertical view.
Front view when Fig. 2 (a) is the expansion of expandable type vertical bar formula elastic covering sheet, I (b) is its vertical view, (c) is its left view.
1 is the drain cover frame board among the figure, the 2nd, and the elastic covering sheet.
Five, the specific embodiment
Earlier cylinder iron produce the drain cover frame board, the diameter of plate hole is got 55 millimeters, and produces the elastic covering sheet with the polypropylene resin, the thickness of cover sheet is got 0.3 millimeter, the width of slice is got 4 millimeters, the elastic covering sheet is curled again, and makes the diameter of the diameter of its oral area less than drain cover skeleton plate hole, be inserted in the hole, unclamp hand, hole wall is close in the moment expansion of elastic covering sheet, press down the oral area of elastic covering sheet at last, the step surface that its ring-type outer is close in the drain cover skeleton plate hole gets final product.
