Description

Drainage structure for preventing mosquito odor and flooding backflow

The present invention relates to a drainage outlet structure that prevents mosquito odor and flooding backflow, in particular to an innovative structure designer that can prevent mosquito odor and flooding backflow.

According to Xizhi, although the drainage outlet on the road provides good drainage, the water in the ditch is easy to breed mosquitoes, and the mosquitoes will fly out of the ditch through the drainage hole set on the ditch cover, endangering the home environment and spreading infectiousness. Diseases pose a threat to life safety. Although drainage outlets can use water ditches to guide water flow to canals or rivers, the water is treated by sewage treatment plants and directed to the sea. However, because the water flow in the ditches cannot be completely drained, so Generally, there will be some water in the ditch. This water is easy to breed bacteria because it does not flow or flows very slowly, causing the ditch to stink, and the water in the ditch has also become a breeding ground for mosquito vectors. For this reason, the water in the ditch Odor and vector mosquitoes can easily enter the living space of people through the through holes covered by the water ditch, further affecting our quality of life, sanitary environment and human health;

In addition, when a flood occurs, the flooding is likely to surge from the drain to the ground, which can easily cause troubles for the people.

That is, the main purpose of the present invention is to provide a drainage outlet structure that prevents the odor of mosquitoes and also prevents flooding. The problem to be solved is to address the odor in the water ditch and the easy passage of vector mosquitoes from the water ditch. The through hole of the cover enters the living space of people, which further affects our quality of life, sanitary environment and human health; in addition, when a flood occurs, the flooded water will easily surge from the drain to the ground, which will easily cause problems for the people. Point to be improved and breakthrough;

The technical feature to solve the problem is mainly to include a frame body with a hollow part penetrating inside. The bottom of the inner peripheral edge of the hollow part is provided with a bottom edge that is bent inwardly, and the top of the outer peripheral edge of the frame is provided with an outwardly bent shape. The upper edge of the upper edge, the space formed between the upper edge and the bottom edge relative to the hollow portion is defined as a valve space; a valve plate, which is made of a buoyant material, and the valve plate is linearly movable In the valve space of the frame, a limit retaining edge is provided on the periphery of the valve plate, the limit retaining edge is just limited to the bottom edge of the frame, and the limit retaining edge is provided with a top edge of the periphery At the top edge, a guide inclined peripheral surface is formed in the valve plate, and a drainage hole is formed at the center of the bottom of the guide inclined peripheral surface; a floating ball is made of a buoyant material, and the floating ball is limited in its movement. In the guide inclined peripheral surface of the valve plate, the float ball is normally closed and positioned on the drainage hole of the valve plate. When the float ball is positioned on the drainage hole, the height of the top of the float ball is the same as that of the movable ball. The top edges of the door panels are level with each other; an upper cover whose bottom edge is positioned exactly on the upper edge of the frame, and the surface of the upper cover is provided with a plurality of holes;

With this innovative and unique design, the present invention allows the floating ball to be positioned on the drain hole of the valve plate under its own gravity under normal conditions, so that the valve space of the frame is formed by the valve plate and the floating ball to form a closed space In this way, it can prevent mosquitoes from entering and exiting and the overflow of marsh gas and odor in the water ditch, and can achieve the purpose of improving environmental sanitation. Moreover, the present invention uses the buoyancy effect of the valve plate itself to make the water The top edge stop limit of the valve plate is located on the bottom surface of the upper cover, and when the float is positioned on the drain hole, the height of the top of the float ball and the height of the top edge of the valve plate are level with each other, so that The top edge of the float ball is also restricted to the bottom surface of the upper cover, so that the valve plate is fully attached to the upper cover by its top edge, and the float ball up and down abuts against the top drainage hole and the upper cover to seal the valve. The space enclosed by the door panel relative to the upper cover to prevent the flooding from continuing to surge to the ground.

Please refer to Figures 1 to 6, which are preferred embodiments of the drainage outlet structure of the present invention for preventing mosquito odor and flooding backflow. However, these embodiments are for illustrative purposes only and are incorporated in the patent application. Not limited by this structure; including:

A frame body (10) penetrates a hollow portion (15) inside. The hollow portion (15) is provided with a bottom edge (12) bent inwardly at the bottom of the inner periphery of the hollow portion (15).
