Description

Drainage filter cover

The present invention is a filter cover which is referred to as a drain filter movable filter cover.

The early social drainage system has not been planned and perfected. As long as the rainfall increases, flooding often occurs. Later, the government began to build water conservancy projects, especially the implementation of its sewer works, in order to help drainage and flooding.

Even nowadays, we often see flooded news on TV. Although the flooding factor is very wide, one of the big problems is blocked in the sewer. Imagine if we usually have garbage and plastic in our daily lives. Bags, leaves, stones, etc. are all stored in the sewer. When there is large water to pass through, the speed and amount of water dredging will be reduced accordingly. It is conceivable that the drainage efficiency and the sewer are unblocked or not. Relatedly, even if we regularly clean up the sewers in these sewers, it is still not enough to face the highly developed society today; therefore, in order to prevent debris from accumulating in the water pipes, we began to install drainage covers on the ground drains. The falling water head and the like prevent the passage of debris, and such a device does reduce the garbage in the sewer, and the drain pipe used in the home is relatively unblocked.

There is a known water outlet filter device which is a water drop head 40 as shown in FIG. 4, and a fixing frame 41 is formed on the upper end of a fixing plate 42. The fixing frame 41 is formed with a fence-like drainage hole and a fixed disk. The bottom of the 42 is formed with a joint seat 43 for installation at a drain port (not shown); when it is rainy, the water drop head 40 can block the debris flowing with the water outside the drain port, but the design thereof There are the following disadvantages: Since the size of the falling head 40 is matched with the size of the drainage hole, the volume is not large, and the drainage hole on the fixing frame 41 is smaller. When there is a slightly large area of fallen leaves and paper dust drifts with the water to the falling head 40, the falling head 40 can be The leaves are isolated, but the leaves and confetti also cover the drain holes of the falling head 40, which will affect the normal drainage of the drain and cause water accumulation.

Therefore, the main purpose of this creation is to provide a drain filter cover, which can mainly freely place the movable filter cover at the water outlet, and can be in contact with the ground in a snug manner, and is convenient to pick and place, and is relatively flexible and convenient to use. At the same time, it can effectively block leaves and debris and is easy to clean.

The technical means for achieving the above purpose is to use the above-mentioned drain movable filter cover, comprising: a mesh cover body having an annular fixing piece and a plurality of vault ribs, wherein one end of each vault rib is respectively fixed to the periphery of the fixing piece The other end of the vault rib extends radially; a floating base has an annular fixing member and a plurality of movable flaps respectively fixed to the other ends of the vault ribs, one end of each movable flap They are respectively pivoted at the lower end of the fixing member.

It can be seen from the above that the water outlet movable mesh cover of the present invention is composed of a mesh cover body and a floating base, and the floating base can be freely biased by the movable flap, so that the bottom of the floating base can be complementarily attached to the ground. In order to fit the flat or uneven ground, the movable net cover can be conveniently placed; and the mesh cover can isolate the debris from the drain port in a wide range, and the cleaning is also very simple.

Referring to FIG. 1 and FIG. 2, a preferred embodiment of the present invention includes a mesh cover 10 and a floating base 20: wherein the mesh cover 10 has a ring shape. The fixing piece 11 and the plurality of vault ribs 13 and the first fixing rod 14 and the second fixing rod 15 are annular, and the fixing piece 11 and the first fixing rod 14 and the second fixing rod 15 are sequentially from the inside to the outside. Concentrically arranged, the fixing piece 11 is formed with an opening 12 for facilitating the user's lifting. One end of each of the vault ribs 13 is respectively fixed to the periphery of the fixing piece 11, and the other end of the vault rib 13 extends radially. The first fixing rod 14 and the second fixing rod 15 are respectively connected; the floating base 20 has an annular fixing member 21 and a plurality of movable flaps 22, and the inner wall of the fixing member 21 and the other end of the vault rib 13 are respectively fixed. One end of each of the movable flaps 22 is pivotally respectively disposed at a lower end of the inner wall of the fixing member 21 and is naturally suspended.

The structure of the present invention can be seen from the above embodiments, and the application mode of the present invention is as shown in FIG. 3. When there is rain or water on the ground, the user places the movable filter cover on the drainage hole, and the rainwater is transmitted through The gap between the adjacent vault ribs 13 and the vault ribs 13' on the mesh cover 10 flows into the drainage hole and blocks debris such as garbage, branches, leaves, etc.; however, if the ground around the drainage hole is not flat, The floating base 20 and the irregular ground will create a gap, and the filtering effect is lost. Therefore, the present novel is rotated and tilted to different angles by the movable flap 22, and the flexible yaw complements the ground to complement the ground. In this case, the adjacent activity The flaps 22 are fence-like and have a filtering effect, so that leaves or debris cannot pass; if the ground around the drain hole is flat, When the movable flap 22' is rotated and yawed to the inner wall of the fixing member 21, the floating base 20 is attached to the ground; in addition, even if there is a small volume of impurities, such as some unavoidable hair, gravel, rubber The ring or the like can be easily removed by lifting the opening 12 formed in the fixing piece 11 of the movable filter cover as mentioned in the foregoing embodiment.

In another preferred embodiment of the present invention, a reflective sheet is placed on the surface of the fixing piece 11 of the mesh cover 10 to provide a reflective effect at night so that pedestrians can avoid it when passing by.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any person having ordinary knowledge in the art can use the present invention without departing from the technical features of the present invention. Equivalent embodiments of the novel modifications or modifications made by the novel teachings are still within the scope of the novel features.
