Description

A rainwater abandonment device for sponge city construction

technical field

The utility model belongs to the technical field of rainwater abandonment devices, in particular to a rainwater abandonment device for sponge city construction.

Background technique

The scarcity of water resources is a global ecological problem, and how to save water resources is a major problem faced by mankind. In the sponge city with the theme of water conservation and water purification, the collection and utilization of rainwater resources is particularly important. During the initial rainfall, the first 2-4mm of rainwater is generally seriously polluted, usually with paper scraps, feces, oil, leaves and other easy pollutants, so the initial rainwater needs to be discarded with a waste flow device, so that it is relatively clean after collection rainwater.

At present, most of the rainwater disposal devices used in the construction of sponge cities on the market have the following problems:

(1) Existing devices often detect the flow of rainwater through sensors, and then choose to discard the flow or start collecting rainwater at a certain time. This kind of device requires a large amount of power equipment and real-time manual monitoring, which is time-consuming, laborious, costly, and inefficient.

(2) Existing devices often realize the collection of discarded flow and rainwater through complex structures. Although they do not require a large amount of electrical equipment for support, such devices are expensive, difficult to maintain, and impractical.

Utility model content

The purpose of the utility model is to provide a rainwater discarding device for sponge city construction to solve the problems of high cost and poor discarding effect of the existing draining device.

In order to achieve the above-mentioned purpose of the invention, the technical scheme that the utility model takes is:

Provide a rainwater waste flow device for sponge city construction, including a flow waste box and a clean water tank connected by an outlet pipe;

The jettison box includes a box body, a water inlet and a drain port arranged on the box body, a floating ball connected with the rod body and fixed in the box body through the rod body, and a partition connected with the slider and fixed in the box body through the slider body, There is a drain opening on the partition, and at least two springs are provided at the bottom of the box to support the partition;

The clean water tank includes a clean water layer and a water outlet.

Preferably, the aperture of the jettison outlet is smaller than the diameter of the floating ball.

Preferably, the aperture of the water outlet is smaller than the apertures of the water inlet and the outlet pipe.

Preferably, the slider is slidably connected with the box body of the clean water tank.

Preferably, the rod body is made of stainless steel.

Preferably, the water purification layer is a filter layer, an adsorption layer and a deodorization layer arranged sequentially from top to bottom.

The rainwater abandonment device for sponge city construction provided by the utility model has the following beneficial effects:

Through ingenious conception and design, the device uses the gravity of rainwater itself to compress the spring, and the spring drives the partition to move downward, so that the floating ball moves upward relatively, blocking the discharge outlet, that is, to complete the discharge of rainwater in the early stage.

At the same time, the slider moves down together with the partition, so that the outlet pipe that was originally blocked by the slider can be turned on, that is, the rainwater abandonment in the early stage is over, and the relatively clean rainwater in the later stage starts to be collected.

The whole device is ingeniously conceived, simple in structure, does not need to be driven by electric equipment, has low cost, high efficiency, is easy to maintain, and has strong practicability and popularization.

detailed description

Below in conjunction with accompanying drawing, the embodiment of the technical solution of the utility model is described in detail:

According to one embodiment of the present application, as shown in Figure 1, this solution is used for the rainwater abandonment device for sponge city construction, including the abandonment flow box 1 and the clean water tank 2 connected by the outlet pipe 10;

The jettison box 1 comprises a box body, a water inlet 3 and a drain port 8 arranged on the box body, one end of the rod body 4 is connected with the inner wall of the box body, and the other end passes through the jettison port 13 on the partition plate 5 and is connected with the floating ball 7, Wherein the rod body is made of stainless steel.

The aperture of the jettison 13 is smaller than the diameter of the floating ball 7 to ensure that the floating ball 7 blocks the jettison 13, that is, the jettisoning process ends and rainwater collection begins. The aperture of the water outlet 8 is smaller than the apertures of the water inlet 3 and the outlet pipe 10, so as to ensure normal rainwater collection in the later stage.

The slide block 9 is fixed on the dividing plate 5 and is slidably connected with the inner wall of the box.

The bottom of the box is provided with at least two springs 6 that are connected with the partition 5 and support the partition 5. The springs 6 can drive the partition 5 to move together, and the partition 5 can drive the slider 9 to move together.

The water purification tank 2 includes a water purification layer 11 and a water outlet 12. The water purification layer 11 is a filter layer, an adsorption layer and a deodorization layer connected sequentially from top to bottom. Multi-level water purification settings ensure the quality of later rainwater collection .

The specific process is that the turbid and easily polluting rainwater in the early stage enters the jettison box 1 through the water inlet 3, and the rainwater flows into the bottom of the box through the jettison 13 on the partition 5, and then flows out through the drain 8.

When the water on the shelf 5 accumulates to a certain capacity, under the action of rainwater gravity, the partition 5 squeezes the spring 6, and the spring 6 contracts to drive the partition 5 to move downward together, that is, the floating ball 7 moves upward until it blocks the discarded Orifice 13, while the slide block 9 moves downward together with the partition plate 5, and the water outlet pipe 10 is conducted.

The rainwater flows into the clean water tank 2 through the outlet pipe 10, and flows through the filter layer, the adsorption layer and the deodorization layer in sequence, wherein the filter layer filters and removes larger diameter solid particles and impurities in the water; the adsorption layer is equipped with activated carbon to absorb small solid particles and organic pigments; the deodorant layer is filled with deodorant balls to remove odors from the water.

After the rainwater is filtered, it flows into the water storage device through the water outlet 12 .

The device is ingenious in conception, simple in structure, does not need to be driven by electric equipment, has low cost, high efficiency, is easy to maintain, and has strong practicability and popularization.

Although the specific implementation of the utility model has been described in detail in conjunction with the accompanying drawings, it should not be construed as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative efforts still belong to the protection scope of this patent.
