Description

Integrated rainwater collection system with automatic abandonment, water storage and overflow

technical field

The utility model discloses a rainwater collection system integrated with automatic flow abandonment, water storage and overflow.

Background technique

Urban rainwater collection and utilization not only saves municipal water, but also reduces the threat of urban flood disasters. In the construction of rail transit, the collection and utilization of rainwater at subway elevated stations can effectively limit the discharge and loss of bridge deck rainwater, and control the pollution of rainwater runoff around elevated lines. It is also in line with urban water-saving policies, the concept of building green subways, and the trend of sponge city construction. .

In the process of rainwater collection and utilization, the quality of the initial rainwater is poor, so the rainwater from the initial rainfall should be discarded, and the relatively clean rainwater from the middle and late rainfall should be collected. At present, there are mainly two types of waste flow devices in the rainwater collection system. One uses electric energy and adopts an automatic control module to control the waste flow and start and stop collection by detecting the collected rainwater quality or the set waste flow rainwater volume; the other is mechanical The type of rainwater abandonment device, the rainwater volume is controlled by the built-in float valve to control the abandonment, collection start and stop. Although this kind of device does not require electric energy, it is large in size and complex in structure. For example, the rainwater collection of the above-ground viaduct of rail transit needs to be arranged along the viaduct, and there are many collection points. If the above-mentioned discarding flow device is used, the following problems will occur:

1. The structure of the waste flow device of the rainwater recovery system is complex;

2. The rainwater abandonment device is affected by factors such as poor outdoor environment and easy damage to the automatic control module, so the system maintenance is complicated.

Utility model content

The purpose of this utility model rainwater abandonment type rainwater bucket is to solve the above-mentioned deficiencies in the prior art, and to provide a rainwater system that realizes automatic initial rainwater abandonment, water storage, and automatic overflow of rainwater through water level control, and solves the problem of relying on flow in the past. Flowmeter, water level gauge and solenoid valve realize the problem of troublesome management and maintenance of flowmeter, water level gauge and solenoid valve in the rainwater system in which the flow is automatically discarded and overflowed.

The technical scheme that the utility model adopts is as follows:

An integrated rainwater collection system with automatic waste flow, water storage and overflow, comprising a rainwater bucket installed on the top of a building, the rainwater bucket communicates with the waste flow box and the water storage box through a rainwater standpipe respectively, The bottoms of the jettison box and the water storage box are all connected with the anti-scour gravel pit.

Further, the rainwater standpipe communicates with the jettison box and the water storage tank respectively through a three-way pipe; when the jettison box is full, the rainwater flows into the water storage tank through the three-way pipe.

Further, the highest point of the rainwater bucket is lower than the lowest point of the building.

Further, the top of the rain bucket is provided with a filter.

Further, a filter is provided in the rainwater riser.

Further, the overflow port communicates with the anti-scour gravel pit through the overflow pipe; when the amount of rainwater reaches the required amount, the excess rainwater is discharged to the ground or the green belt through the overflow pipe.

Further, the jettison box and the water storage box are arranged on the ground around the building, the ground next to the bridge pier or in the green belt.

Further, the rainwater standpipe is attached to the exterior wall of the building or the bridge pier of the viaduct.

Further, a drain valve is installed at the bottom of the water storage tank.

Further, the jettison box and the water storage tank are provided with inspection ports.

Further, the jettison box is provided with an air release valve.

The buildings in front include ordinary houses and viaducts.

The beneficial effects of the utility model are as follows:

1. Reasonable and simple structure, convenient assembly and maintenance;

2. Simple operation, no need for automatic control of electric valves, environmental protection and energy saving, increasing the availability of water resources, in line with the policy of sponge city construction, and suitable for popularization and use.

detailed description

The utility model provides a rainwater system that realizes the automatic abandonment, storage and automatic overflow of rainwater at the initial stage through water level control, and solves the problem that the automatic control system of the previous rainwater system realizes the automatic abandonment, storage and automatic overflow of rainwater at the initial stage. flow problem.

As shown in Figure 1, the utility model consists of 80-mesh steel wire dense mesh 1, 87-type rainwater bucket 2, rainwater standpipe 3, filter 4, waste flow box 5, water storage tank 6, tee pipe 7, overflow Pipe 8, anti-scouring gravel pit 11 are formed.

The 80-mesh steel wire dense mesh 1 and the 87-type rain bucket 2 are arranged on the roof or the viaduct surface; the 80-mesh steel wire dense-mesh 1 arranged on the 87-type rain bucket 2 isolates relatively large debris such as leaves in the initial rainwater. The 80-mesh steel wire mesh 1 fully covers the 87-type rainwater bucket 2 and is fixed on the roof or viaduct deck.

The rainwater riser 3 is attached to the exterior wall of the building or the pier of the viaduct. A three-way pipe 7 is arranged on the rainwater standpipe 3, and rainwater flows into the water storage tank 5 through the three-way pipe 7 after the water in the jettison box is full. Rainwater riser 3 adopts PE pipe.

The filter 4 is arranged on the rainwater riser 3 at a height of 0.5 m from the top of the water storage tank. The filter 4 filters some impurities with smaller particle sizes in the initial rainwater.

An inspection port 12 and an air release valve 13 are provided on the jettison box 5; an inspection port 14 is provided on the water storage tank.

The jettison box is set on the ground around the building or in the green belt and on the ground next to the bridge pier or in the green belt, and the box body is made of PE material.

The water storage tank is set on the ground around the building or in the green belt and on the ground or in the green belt next to the pier. The side wall of the water storage tank is provided with an overflow pipe. When the rainwater reaches the required amount, the excess rainwater is discharged to the ground or greenbelt. The cabinet is made of PE material.

The working principle of the utility model is:

When it rains, the rainwater falls on the roof or the viaduct surface. The rainwater first passes through the 80-mesh steel wire dense mesh 1 to isolate the leaves and other large debris in the initial rainwater, and is collected by the 87-type rainwater bucket 2, and passes through the rainwater riser 3. The filter 4 filters a part of debris with a smaller particle size. The initial rainwater enters the jettison box 5 after being filtered by these two filters. After the jettison box 5 is full of water, the rainwater will flow in through the three-way pipe 7 provided on the rainwater standpipe 1. The rainwater storage tank 6 stores rainwater. After the stored rainwater reaches the required amount of rainwater, it will be discharged to the anti-scouring gravel pit 11 on the ground or in the green belt through the overflow pipe 8 on the water storage tank 6 to realize the automatic drainage of rainwater. Abandoned flow, water storage, overflow. When using water after the rain, water can be taken from the water intake 9; when the water tank is drained, it can be drained by opening the drain valve 10.

Although the structural form of the present utility model has been described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present utility model. Those skilled in the art should understand that on the basis of the structural form of the present utility model, those skilled in the art do not need to pay Various modifications or deformations that can be made through creative labor are still within the protection scope of the present utility model.
