technical field

The invention relates to a rainwater abandonment well, in particular to a permeable automatic reset rainwater abandonment well, which belongs to the technical field of rainwater abandonment wells.

Background technique

In the early stage of rainfall, after the rainwater falls to the ground, it will contain a large amount of impurities such as sediment, particulate matter and floating matter. It is often necessary to use an abandonment device or abandonment well to intercept the initial rainwater, so that the initial rainwater can be discharged to the sewage treatment plant for treatment. However, the existing rainwater abandonment wells can only intercept the initial rainwater, and cannot collect the relatively clean rainwater in the later stage of the rainfall, resulting in too much abandoned rainwater in the later stage of the rainfall, which not only greatly wastes resources, but also aggravates the sewage treatment. The plant handles the burden of cleaner rainwater. In addition, the existing rainwater abandonment well has a complex structure, and has special requirements on the shape and structure of the well itself. When the construction method of the old well reconstruction is used to build the rainwater abandonment well, a lot of manpower and financial resources are required, and the cost is high and the cost is high. Inconvenient to maintain.

Detailed ways

1 to 5, a specific embodiment of the present invention is described in detail, but does not make any limitation to the claims of the present invention.

As shown in Figures 1 to 5, a permeable automatic reset rainwater abandonment well includes a well body 1, a water inlet pipe 2, an overflow pipe 3, an interception pipe 14, a partition 10, a support rod 12, a bracket 13, container device, spring 8;

The wellbore 1 is provided with a water inlet, an overflow outlet and an interception port, the water inlet is communicated with the water inlet pipe 2, the overflow port is communicated with the overflow pipe 3, and the interception port is located at the bottom of the wellbore 1 and is connected with the interception pipe 14. connected;

The baffle 10 is horizontally installed in the well 1 through the baffle 10 bracket. The shape and size of the baffle 10 are the same as the cross-sectional shape and size of the well 1. The baffle 10 is provided with an opening 15, and the opening 15 is provided with an opening 15. The center line and the center line of the water inlet are located on the same vertical plane;

The bracket 13 is arranged just below the opening 15, the bracket 13 is fixedly connected with the partition plate 10 through the support rod 12, and the bracket 13 is provided with a through hole for the long connecting rod to pass through;

The container device includes a container wall 4, a rubber ring 6, a container support rod 7, a permeable concrete 5 and a long connecting rod 9, the container wall 4 is cylindrical in shape, and the top position of the container wall 4 is lower than the water inlet and the overflow port. In the lowest position, the outer diameter of the container wall 4 is larger than the diameter of the opening 15, the inner diameter of the container wall 4 is the same as the diameter of the opening 15 and the diameter of the nozzle of the interception opening, and the rubber ring 6 is sleeved outside the container wall 4 and is located in the container wall 4. At the bottom, the rubber ring 6 plays a sealing role, the container support rod 7 is arranged in the container wall 4 and is located at the bottom of the container wall 4, the permeable concrete 5 is laid on the container support rod 7; the spring 8 is sleeved outside the long connecting rod 9 and It is located between the container support rod 7 and the rack bracket 13 .

The working principle of the present invention is as follows:

In the early stage of rainfall, the amount of rainwater is small and dirty, and the rainwater entering the well 1 from the water inlet pipe 2 directly flows through the opening 15 on the clapboard 10 to the intercepting pipe 14 to be discharged to complete the abandoned flow of the initial rainwater;

When the rainfall increases in the later stage, the parabolic horizontal distance of the free outflow of the water flow from the water inlet pipe 2 in the well increases until the water flow falls into the container wall 4. Since the permeable concrete 5 at the bottom of the container wall 4 sees water slowly, the container wall 4. The water level in the container will rise quickly, and the gravity of the container device will gradually increase, which will cause the compression spring 8 of the container device to move downward until the bottom of the container wall 4 blocks the opening 15 (as shown in Figure 5), and the opening 15 is blocked. After the shelter, most of the rainwater flows out from the overflow pipe 3 in an overflow way, and then enters the water storage system to be collected. A small amount of rainwater slowly penetrates through the permeable concrete 5 and then flows into the interception pipe 14 for drainage; The device will not be reset in time, and the relatively clean rainwater in the well 1 can continue to flow out from the overflow pipe 3 to the water storage system for a certain period of time. The rainwater in 1 can only infiltrate slowly through the permeable concrete 5, and the gravity of the container device gradually decreases with the continuous flow of rainwater in the container wall 4. When the gravity of the container device is less than the elastic force of the spring Under the action of , the container device is reset (as shown in FIG. 4 ), and the remaining rainwater outside the container wall 4 in the well body 1 is discharged into the intercepting pipe 14 through the opening 15 to flow away, so as to prepare for the next rainwater collection.

To sum up, the present invention has the following advantages:

(1) The present invention is designed according to the rainwater characteristics that the initial rainwater volume is smaller and dirty, and the later rainwater is relatively clean. The present invention can realize the abandonment of the initial dirty rainwater and the continuous collection of the later clean rainwater. In addition, Therefore, when the amount of rainwater in the later stage is small, the abandonment well of the present invention can still continue to collect a certain amount of rainwater, which is beneficial to reduce the abandoned flow of rainwater in the later stage and save resources. The invention has great significance for promoting the construction of sponge city and the utilization of rainwater in green buildings.

(2) The present invention has a simple structure, can operate automatically without external force driving, is convenient to maintain, and has low investment cost.

(3) The present invention has no special requirements for the shape and structure of the abandoned well itself, whether it is an integration of new and old abandoned wells, closed or open abandoned wells with cover plates, brickwork, concrete or other materials.
