Abstract

The invention discloses a gutterway cover, which is characterized by the following: the gutterway cover consists of at least one body and complex filter elements; there are complex slotted holes passing through body; the filter element has the air-proof feature, which can provide for water flow and stop the air current from circulating; the filter element can make the gutterway cover drain in normal and stop the mosquito and marsh gas from outcoming from gutterway cover.

Description

Drain cover

Technical field

The present invention relates to a kind of drain cover structure, refer to a kind of drain cover that prevents that mosquito in the gutter and foul smell and biogas from overflowing especially.

Background technology

The tradition drain cover directly is erected at above the ditch, and these ditches must be provided with some perforates, makes water can flow to the inside, ditch.Yet, owing to water these drain covers of can flowing through flow to ditch the inside, so relatively, ground rubbish and earth also can go inside flowing into the ditch via these perforates, make the ditch that the situation of silting up be arranged often and make the quite difficulty that their cleaning works become.Moreover, because these perforates are direct and the ditch is connected, make foul smell and biogas that the ditch produced also can overflow by these perforates, it is quite uncomfortable that these foul smell and biogas sometimes can make us.In order to prevent the effusion of foul smell and biogas, someone has developed sealed type drain cover (No. 514086, TaiWan, China patent announcement), as shown in Figure 1, mainly be that a plate body 2 is set in the bottom of drain cover 1, this plate body 2 survives board-like the connection with drain cover 1, and as shown in Figure 2, this plate body 2 is affixed on the below of ditch lid 1 usually, and the drain hole 11 of drain cover 1 can be covered, can prevent that thus foul smell and the biogas in the gutter from overflowing.When the rainy day, as shown in Figure 3, when rainwater during down to a certain amount, plate body 2 is subjected to rainwater pressure, and plate body 2 promptly can be pressed down by the weight of rainwater, forms the unlatching shape, and rainwater can be entered in the ditch by the outfall 11 of drain cover 1.But, because this plate body 2 survives board-like design, can overflow immediately when foul smell and biogas that plate body 2 is opened in the moment ditch, therefore this closed drain cover there is no the effusion that prevents foul smell in the ditch and biogas in full force and effect.In addition; when rainwater is big inadequately; this plate body 2 can't be opened, and causes partial product watery, moreover; with the passing of time the joint regular meeting of this plate body 2 and drain cover 1 because of engaging; cause plate body 2 to open, cause drain cover 1 can't reach drain function, so this sealed type ditch lid still has and do not improve part to the greatest extent; therefore how the structure that prevents the drain cover that the mosquito ditch in or foul smell and biogas are overflowed that has more effect is provided, is the worth big problem that develops of drain cover producer in fact.

Summary of the invention

Main purpose of the present invention is to provide a kind of drain cover, and the draining normally of this drain cover can stop mosquito in the gutter or foul smell and biogas to be overflowed from drain cover again effectively.

Realize that above-mentioned purpose technical scheme of the present invention is, a kind of drain cover, this drain cover includes a body and a filter element at least, have a plurality of slotted eyes that run through body on this body, the percolation that this slotted eye can supply water, below the slotted eye of body, be provided with filter element in addition, this filter element has airtight and non-watertight characteristic, and the circulation that can supply water, but the circulation of energy barrier gas, make the drain cap can normal draining thus, but can stop the mosquito gutter in or foul smell and biogas to be overflowed effectively from drain cover, thus the use effect of lifting drain cover.

The specific embodiment

In order to allow above-mentioned and other advantage of the present invention can be more obvious, preferred embodiment of the present invention cited below particularly, and cooperate institute's accompanying drawing, be described in detail below.

See also shown in Figure 4ly, drain cover 3 of the present invention includes a body 4 at least, and a plurality of filter element 5.

This body 4 is provided with a plurality of slotted eyes 41, and this slotted eye 41 runs through body 4, and the percolation freely that can supply water.

Filter element 5, for the flexible nylon yarn of tool, plastics silk or uncorruptible fiber material are made, characteristic by the fiber material, can for the rainwater that gravity arranged freely percolation cross filter element 5, but have and can effectively stop gas through filter element 5, make filter element 5 become airtight but non-watertight characteristic, and the function of draining is arranged, this filter element 5 is arranged on the below of the slotted eye 41 of body 4 by modes such as cemented or lockings in addition.

The present invention mainly is provided with filter element 5 by slotted eye 41 belows of body 4, as shown in Figure 5, when rainy day, rainwater can flow to via the slotted eye 41 of

body

4,5 rows advance in the gutter (representing the travel direction of water among the figure with W) through filter element, mosquito, foul smell and biogas in gutter at ordinary times can be filtered that member 5 intercepts and can be by the slotted eye 41 of body 4 overflow (representing the travel direction of foul smell among the figure with A).

For another shown in Figure 6, the present invention is in order there to be the better mosquito that prevents, foul smell and biogas are in the ditch, between the slotted eye 41 and filter element 5 via body 4, more be provided with resistor 6, this resistor 6 is made by the flexible glue class of tool material, when rainwater will enter the gutter, rainwater can be flowed into by the slotted eye 41 of body 4, and oppress resistor 6 by the gravity of amount of rainfall and be absorbed in to filter element 5, be the rubber-like nylon yarn because of filter element 5 simultaneously, plastics silk or uncorruptible fiber material are made, and by the characteristic of fiber material, and suitable elasticity are arranged, can flow in the filter element 5 for the resistor 6 of rainwater, enter in the gutter again by the gravity extrusion.And mosquito in the gutter or foul smell and biogas then are filtered member 5 earlier to intercept, and the resistor 6 that is affixed on again on the filter element 5 stops fully, can more make mosquito or foul smell and biogas in the gutter by this, can't overflow in the slotted eye 41 of body 4.

Though the present invention discloses with aforementioned preferred embodiment, so it is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the present invention, and when doing various changes and modification.

Claims
