Description

A drainage device for a rainwater separation and storage system

technical field

The invention relates to a drainage device, in particular to a drainage device suitable for a rainwater separation and storage system.

Background technique

In order to separate the initial rainwater and adjust and store the later rainwater, the rainwater sewer network of urban streets and large factories should use the initial rainwater separation system. When it rains, the initial rainwater enters the waterway through the water inlet pipe and then enters the initial rainwater tank. As the water level rises, the later rainwater enters the storage tank through the water inlet hole of the storage tank. After the rain stops, the water level of the initial rainwater tank drops. However, due to the high water level and high water pressure of the water channel, it is often necessary to use a siphon to realize the connection between the water channel and the initial rainwater pool, so as to reduce the water level in the water channel, which is extremely inconvenient, so a device that can automatically drain water is installed more reasonable.

Contents of the invention

The technical problem to be solved by the present invention is to provide a device capable of automatically draining the rainwater separation and storage system.

In order to solve the above technical problems, a drainage device for rainwater separation regulation and storage system, the separation regulation and storage system includes a first regulation and storage system, a second regulation and storage system and a third regulation and storage system, the first regulation and storage system , The second regulation and storage system and the third regulation and storage system are the initial rainwater tank, the water passage and the storage tank respectively. Fix the upper wall and the lower wall of the initial rainwater pool, the fixed rod is covered with a floating plate, the floating plate can slide up and down freely, the floating plate is provided with a sealing head, at the position corresponding to the position of the sealing head A sealing seat is provided, a hose is provided at the lower end of the floating plate, one end of the hose is connected with the sealing head, and the other end of the hose is provided with a connecting pipe, the connecting pipe is located in the pool wall of the initial rainwater pool, and is connected with the water channel connected.

A drainage operation method for a rainwater separation regulation and storage system, characterized in that: the method for implementing drainage by the drainage device includes the following steps:

Step 1: When it rains, the initial rainwater first enters the initial rainwater pool after passing through the water channel;

Step 2: As the water level in the initial rainwater pool rises, the buoyancy of the floating plate drives the hose up along the fixed rod. When the water level rises to a certain height, the sealing head contacts the sealing seat to seal the pipe and prevent rainwater from entering primary stormwater ponds;

Step 3: The water level in the water channel continues to rise, and the later rainwater enters the storage tank;

Step 4: When the rainfall decreases or the rain stops, when the water level in the initial rainwater pool drops, the floating plate descends along the fixed rod, the sealing head is separated from the sealing seat, and the water in the water channel passes through the connecting pipe, hose, and sealing head Enter the initial rainwater pool and reduce the water level in the water channel.

The beneficial effect of adopting the above structure is that: when the initial rainwater enters the initial rainwater pool, it will

As the level rises, the floating plate drives the hose up along the fixed rod under the action of buoyancy. When the water level rises to a certain height, the sealing head contacts the sealing seat to seal the pipe, and the rainwater no longer enters the initial rainwater pool through the connecting pipe. The rainwater in the late stage of the water level enters the storage tank; when the water level in the initial rainwater tank drops, the floating plate descends along the fixed rod, the sealing head breaks away from the sealing seat, and the water in the water channel can enter through the connecting pipe, hose and sealing head The initial rainwater pool achieves the purpose of reducing the water level in the water channel. The drainage device does not need external equipment and power control, and can automatically discharge water, which is extremely convenient.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, a drainage device for a rainwater separation regulation and storage system, the separation regulation and storage system includes a first regulation and storage system, a second regulation and storage system and a third regulation and storage system, the first regulation and storage system , the second regulation and storage system and the third regulation and storage system are the initial rainwater tank 1, the water passage 2 and the storage tank 3 respectively, and the drain device is arranged in the initial rainwater tank 1, and fixed The rods 4 are respectively used to fix the upper wall and the lower wall of the initial rainwater tank 1. The fixed rods 4 are covered with a floating plate 5, and the floating plate 5 can slide freely up and down. The floating plate 5 is provided with a sealing head 6, A sealing seat 7 is provided at the position corresponding to the position of the sealing head 6 on the top of the initial rainwater pool, and a hose 8 is provided at the lower end of the floating plate 5, one end of the hose 8 communicates with the sealing head 6, and the other end of the hose 8 is provided with a connecting pipe 9.
