Description

Plant rainwater recycling device

technical field

The utility model relates to a rainwater recycling device, in particular to a rainwater recycling device on the roof of a large factory building.

Background technique

At present, the shortage of water resources has become an important factor restricting the economic development in many areas of our country. As a precious fresh water resource, rainwater has not attracted our attention, especially as a factory with a large water consumption. Most of the current factory buildings are equipped with multiple drainage buckets, which are used to discharge natural precipitation through the drainage buckets, and then through the riser to the ground, and then flow into the rain drainage system or send it to the sewage treatment station together with the production sewage for discharge. my country is a water-poor country with serious shortage of water resources. At present, most factories do not use rainwater resources and waste them in vain.

The present invention aims to provide a device to utilize the rainwater resource on the roof of the factory building to alleviate the problem of water resource scarcity.

Utility model content

The purpose of this utility model is to provide a plant rainwater recycling device to solve the shortcomings in the background technology.

Plant rainwater recovery and utilization device, including filter screen, branch rainwater pipe, rainwater collection pipe, ultrasonic liquid level sensor, time control valve, water pipe, V-shaped water pipe, water storage tank, and viewing window. The filter screen is laid on the roof of the factory building On the top, there is a branch rainwater pipe under the filter screen, the branch rainwater pipe is connected to the rainwater collection pipe, and the rainwater collection pipe is connected to the storage tank through a V-shaped water pipe. The ultrasonic liquid level sensor, time control valve and visual window are arranged under the rainwater collection pipe , the height of the ultrasonic sensor does not exceed the level of the connecting pipe between the V-shaped water pipe and the reservoir.

The utility model includes the design of the roof filter screen, rainwater pipe and storage tank. According to the characteristics of the large roof of the factory building, a plurality of branch rainwater pipes are specially designed, and a three-dimensional coarse filter is set at the connection between the roof and the rainwater pipe, and the rainwater pipes are collected into the main rainwater pipe. , the end of the V-shaped water pipe is connected with the rainwater storage tank.

During the rainy season, the rainwater enters the sedimentation tank through the rainwater roof filter and the collection pipe for storage. The initial rainwater will be discharged through the rainwater collection pipe and the lower drain of the V-shaped water pipe because it carries a large amount of dirt such as leaves and building debris.

Beneficial effect:

The utility model patent can effectively prevent leaves and other sundries from entering the rainwater pipe to cause blockage at the initial stage of rainfall. According to the characteristics of small amount of rainwater but serious pollution in the early stage of rainfall, an ultrasonic chain control device is used to discharge the sewage, and the rainwater can be observed through the visible window. In terms of quality, the V-shaped tube design is adopted, which has no power consumption, saves costs, and plays a role in buffering rainwater and particle precipitation. Composed of water storage tanks, the equipment is simple, low in cost, and equipped with automatic interlocking devices, which can effectively save manpower and space resources.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1, the plant rainwater recycling device includes filter screen 2, branch rainwater pipe 3, rainwater collection pipe 4, ultrasonic liquid level sensor 5, time control valve 6, water pipe 7, V-shaped water pipe 8, water storage tank 9, Visible window 10, the filter screen 2 is tiled on the roof 1 of the factory building, a branch rainwater pipe 3 is arranged under the filter screen 2, the branch rainwater pipe 3 is connected to the rainwater collection pipe 4, and the rainwater collection pipe 4 is connected to the water storage tank through a V-shaped water pipe 8 9. An ultrasonic liquid level sensor 5, a time control valve 6 and a viewing window 10 are arranged under the rainwater collection pipe 4, and the height of the ultrasonic sensor 5 does not exceed the connecting pipe between the V-shaped water pipe 8 and the reservoir 9 level.

When rainfall occurs, the rainwater is collected by the roof 1 of the factory building to the branch rainwater pipe 3 arranged around the roof, and the large debris such as leaves and building debris in the water are filtered out by the filter screen 2, and then collected into the rainwater collection pipe 4, the dirt is more serious The initial rainwater is first in the rainwater collection pipe 4. When the ultrasonic liquid level sensor 5 senses the rainwater, the automatic interlock device will automatically open the time control valve 6, and the rainwater with serious initial dirt will be discharged from the outlet pipe 7, and the amount of rain and water will be discharged. The time can be adjusted according to the local rainwater intensity and the area of the factory building, and can be determined according to the local rainwater intensity formula and the roof area of the factory building. After the initial rainwater is discharged, the time control valve 6 is automatically closed, and then the rainwater will overflow into the reservoir 9 through the V-shaped water pipe 8, and the rainwater will be used for greening or production in the factory after precipitation.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the industry should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model.
