Description

Outlet barrier cover

The present invention relates to a mesh cover for filtering impurities, and more particularly to a drain outer cover.

As shown in Fig. 9, when the water drop cover E of the prior art is installed on the drain port on the roof, the rainwater drainage is said to be smooth in the state where the roof is clean and free of debris, but as time passes, the roof must accumulate some dust. , debris, fiber, etc., if the roof has flower beds, potted plants, flower stands and other plants, there will be a considerable amount of fallen leaves on the roof. When the plant leaves fall, it will accumulate around the falling water cover E as the rainwater flows to the drain. The larger blades will block the cover hole E1 of the falling water cover E as long as a few pieces, causing the drainage to be unsatisfactory. Rainwater is accumulated on the roof, which may cause accidents such as roof leaks in the future. If it is a small leaf, the falling water cover E can not be blocked, and the fine leaves flow into the drain with the rainwater, which is also easy to form a blockage of the drain pipe.

Due to the above factors, the following problems are often caused around the roof and the water drop cover E.

1. It is necessary to clean the roof frequently and keep the roof clean, especially before the typhoon and rainy season. Otherwise, the garbage on the roof will cause the drainage of the drainage port to be unsatisfactory when it rains. The debris will accumulate around the falling water cover E. And the small debris will penetrate the cover hole E1 of the falling water cover E, which is easy to cause the drainage pipe to block, which causes trouble in cleaning.

2. If there is any type of planting on the roof, it is necessary to diligently clean the roof, especially around the water cover E and the drain. It needs to be handled carefully.

3. Since the typhoon and rainwater increase the amount of fallen leaves, the prior art water hood E is easily blocked by fallen leaves due to its small surrounding area, and a considerable amount of leaves are accumulated around the water hood, causing water to accumulate on the roof. In the case of heavy rain, it is necessary to quickly remove rainwater, but it is not easy to drain due to the large accumulation of leaves. At this point, someone needs to keep the leaves in the rain cover E and the drain around the water to clean the leaves, so that the rain can be smoothly eliminated. It is very inconvenient to stand around the falling water hood E during heavy rain.

In order to solve the problem that the defoliation or debris is easy to accumulate and block the area of the cover hole of the prior art water drop cover, the purpose of the present invention is to provide a drain outer layer barrier cover which is arranged around the drain port and has a base and The barrier member, the outer layer of the base is gently sloped, leaves or debris will stay on the outer layer of the base, and the rain will flow from the bottom of the base to the water drop cover and the drain, so that the leaves or debris will not cause the drain Or blockage of the drop cover.

The technical means used in the present invention is to provide a drain outer layer barrier cover, which comprises a plurality of hard mesh wires interwoven to form a three-dimensional net body in a shape of a surrounding fence, the outer barrier cover of the drain port can surround a drain port. And comprising: a base having a bottom and a top, the outer layer of the base is gently sloped from the bottom to the top, and the bottom of the base has an area larger than an area of the top of the base; wherein the base The mesh density of the outer layer is smaller than the mesh density of the inner layer of the base; and a barrier member integrally coupled to the top of the base and having a bottom portion and a top portion, wherein the outer layer of the barrier member has a mesh density smaller than the The mesh density of the inner layer of the barrier.

The specific benefits and enhancements that can be obtained from the outer barrier of the drain provided by this creation include at least:

1. Blocking debris while facilitating rainwater flow: Since the outer layer of the creation base is gently sloped, leaves or sundries will stay on the outer layer of the base, and rainwater will flow from the bottom of the base to the water drop cover and the drain. Therefore, leaves or sundries do not cause blockage of the drain or the water hood, which is very convenient and practical.

2. Gradual blocking effect: Because the mesh density of the outer layer of the base is smaller than the mesh density of the inner layer of the base, it also means that the mesh of the outer layer of the base is relatively thin, and the mesh of the inner layer of the base is dense; the mesh of the outer layer of the base is filtered first. Large debris, and the inner layer of the base further filters out small debris, so the rainwater flows to the drain or the water hood is almost free of debris, so the drain or the water hood is not easy to block. In the same way, the barriers have the same effect.

3. Expanding the barrier area: When the creation is placed around the periphery of the water hood, the area is larger than the water hood, so that the barrier area of the debris around the water hood can be enlarged, and the water hood is not blocked immediately due to some debris. Since the blocking area is large, it is possible to block a lot of debris, and the user waits until a certain amount of debris is accumulated, and it is convenient to clean it after a period of time.

4. It can be disassembled at any time: the creation can be installed around the general water hood by means of the buckle, and it can be disassembled and cleaned at any time, which is very convenient.

5. Conducive to the passage of rain: The base and the barrier of the creation are hollow. Compared with the three-dimensional net body which is closely interwoven and has no hollow part, the rainwater is less blocked from the outside to the inside. This creation is beneficial to rain. Quickly flow from the outside to the inside and the drain.

6. Block the debris falling above: the density of the mesh at the top of the barrier is greater than the density of the mesh at the bottom of the base. The mesh at the top of the barrier is dense enough to block the fallen leaves or debris above, and the mesh at the bottom of the base is sparse. It is good for rainwater to pass.
