Description

A rainwater automatic collection and emptying device

technical field

The utility model relates to an automatic rainwater collection and emptying system, in particular to a rainwater collection system suitable for urban streets and large factories.

Background technique

The scarcity of water resources has increasingly become one of the important reasons affecting economic development and people's quality of life. How to efficiently use rainwater resources has become a new topic before us. In the rainwater collection, the dirt and sludge of the rainwater are isolated, and the rainwater automatic collection and emptying system of the present invention has certain utilization value. The isolated dirt and sludge will be treated and discharged along with the sewage pipes to the sewage treatment plant, and then the water in the clear water pool can be reused. It is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, etc. field, and more and more into the daily life of ordinary people.

Utility model content

The technical problem to be solved by the utility model is a system that not only effectively collects clean rainwater for reuse, but also automatically empties the dirt and sludge in the rainwater.

In order to solve the problems of the technologies described above, the technical solution provided by the utility model is as follows:

A rainwater automatic collection and emptying device is composed of a water passage, a hydraulic drain valve, a filter wall, an anti-backflow device, a rainwater collection pool and a clear water pool. The water passage is arranged on one side of the rainwater collection pool. The rainwater collection pool and the clean water pool are connected by a filter wall. An anti-backflow device is installed at the lower end of the filter wall. The anti-backflow device is located in the clean water pool.

The hydraulic drain valve is composed of a gate, a base, a main shaft, a water collecting bucket, a fixed bucket shaft, a positioning pin and a lever.

The gate is fixedly placed on the base, the gate is movably connected to the main shaft, the main shaft is movably connected to the fixed bucket shaft through the lever, the water collection bucket is connected to the lever through the fixed bucket shaft, and the positioning pin is placed on the base.

The beneficial effects of the utility model are: the utility model can not only effectively collect clean rainwater, but also automatically empty the dirt and sludge in the rainwater. The whole process does not need manual, mechanical and electric control, and is suitable for urban rainwater collection. medium and requires no maintenance.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail.

As shown in Figure 1, the utility model is a rainwater automatic collection and emptying device, which is composed of a water passage 1, a hydraulic drain valve 2, a filter wall 3, an anti-backflow device 4, a rainwater collection pool 5 and a clear water pool 6 , the described water channel 1 is placed on one side of the rainwater collection tank 5, and the rainwater collection tank 5 and the clear water tank 6 are connected by a filter wall 3, and the lower end of the filter wall 3 is provided with an anti-backflow device 4, an anti-backflow device 4 Located in the clean water pool 6, the bottom of the rainwater collection pool 5 is provided with a sewage outlet, and a hydraulic drain valve 2 is arranged on the sewage outlet.

Described hydraulic drain valve 2 is made up of flashboard, base, main shaft, water collecting bucket, fixed bucket shaft, positioning pin and lever.

The gate is fixedly placed on the base, the gate is movably connected to the main shaft, the main shaft is movably connected to the fixed bucket shaft through the lever, the water collection bucket is connected to the lever through the fixed bucket shaft, and the positioning pin is placed on the base.

The working principle of the utility model is as follows:

When it rains, the rainwater enters the rainwater collection tank 5 through the water channel 1;

Along with the rise of the water in the rainwater collection tank 5, the rainwater seeps through the filter wall 3 and flows into the clear water tank 6 by the anti-backflow device 4. Simultaneously along with the rise of the water level of the rainwater collection tank 5, the hydraulic drain valve 2 buoys are filled with water and the water level continues to rise to the liquid level of the clear water tank 6 thereupon;

After the rainfall decreases or the rain stops, the water level of the clear water pool 6 slowly drops during the later period of utilization. Due to the water level difference, the water staying in the rainwater collection pool 5 enters the clear water pool 6 through the filter wall 3 again;

When the water level in the rainwater collection tank 5 fell below the hydraulic drain valve 2, the valve plate was opened due to the gravity of the water in the buoy and the gravity of the buoy, so that the dirt and sewage deposited at the bottom of the pond were discharged from the sewage outlet.
