Description

A rainwater drainage device

technical field

The utility model relates to rainwater recovery and utilization equipment, in particular to a rainwater abandonment device.

Background technique

Rainwater abandonment, also known as rainwater initial abandonment, is mainly used in rainwater collection and utilization systems. Generally, when collecting rainwater from roofs, hardened ground, lawns and other rainwater collection media, since the initial rainwater will contain pollutants such as bird droppings, paper scraps, miscellaneous dust, oil stains, etc., the initial part of the rainwater needs to be used A jettison device or a jettison well makes it a discard, and then collects the follow-up clean rainwater. If the rainwater is not well discarded at the initial stage, impurities will flow into the rainwater well or storage tank, which will not only increase the working strength of the filter and cause the filter to be clogged, but also the impurities will be deposited at the bottom of the pool after a long time, which will bring trouble to the later cleaning work. Very big troubles come, and even cause the whole system to be paralyzed.

Most of the current rainwater abandonment devices are electronically controlled. When the discharge flow is large and the rainwater well or storage tank is flooded by the discarded rainwater, it is easy to cause leakage or failure of electronic components, and the reliability is poor, especially when leakage occurs. security risks.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a rainwater discarding device with a simple structure, reliability, and no potential safety hazards such as electric leakage.

In order to achieve the above purpose, the technical solution of the utility model is: a rainwater abandonment device, including a sewage well, the sewage well is connected with a water inlet pipe, a drain pipe and a waste flow pipe, and a partition is arranged in the sewage well, The water inlet pipe and the drain pipe are located above the partition, the drain pipe is located below the partition and has a diameter smaller than that of the water inlet, the partition is provided with a discharge hole, and a first buoy is provided above the partition. The first floating ball is connected with the blocking member of the drain hole.

As a further preference of the above technical solution, the blocking member for the jettison hole is a second floating ball, and the volume of the second floating ball is smaller than that of the first floating ball.

Compared with the prior art, the utility model has the advantage that the rainwater discarding device disclosed in the utility model is provided with a water inlet pipe and a drain pipe above the sewage well, and a discarding pipe is arranged below the sewage well, and the diameter of the discarding pipe is Smaller than the water inlet pipe, a partition plate is set in the sewage well, and an abandonment hole is opened on the partition plate, and the opening and closing of the abandonment hole are controlled by the first floating ball and the blocking member of the abandonment hole. The initial rainwater enters the abandonment well from the inlet pipe, and then Discharge after passing through the jettison hole and the jettison pipe; because the diameter of the jettison tube is smaller than the diameter of the water inlet pipe, the water level in the jettison well will become higher and higher, and under the action of buoyancy, the first floating ball will carry the jettison hole The blocking member rises until it blocks the discharge hole; the follow-up rainwater will be discharged from the drain pipe, and finally enter the follow-up collection device to be collected. The rainwater discharge device of the present invention is simple in structure, reliable, long in service life, and fully mechanical The structure avoids safety hazards such as electric leakage.

Description of drawings

Fig. 1 is a structural schematic diagram of a rainwater discarding device of the present invention.

Among the figure: 1 sewage well, 2 water inlet pipe, 3 drain pipe, 4, abandonment flow pipe, 5 dividing plate, 51 abandonment flow hole, 6 first floating ball, 7 abandonment flow hole plugging piece.

detailed description

The structure and principle of the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the rainwater abandonment device of the present embodiment includes a sewage well 1, which is connected with a water inlet pipe 2, a drain pipe 3 and an abandonment pipe 4, and is provided with a partition in the sewage well 1. plate 5, the water inlet pipe 2 and the drain pipe 3 are located above the partition 5, the discarding pipe 4 is located below the partition 5 and has a smaller diameter than the inlet pipe 2, and the partition 5 is provided with a discarding hole 51, a first floating ball 6 is provided above the partition plate 5, and a plugging member 7 for the flow hole is provided below the partition plate 5, and the first floating ball 6 is connected with the blocking piece 7 for the flow hole, wherein the The plugging part 7 of the discarded orifice is a second floating ball, and the volume of the second floating ball is smaller than that of the first floating ball 6. The connection between the first floating ball 6 and the second floating ball adopts telescopic, rod pieces etc. are available.

The specific working process of the rainwater abandonment device of this embodiment: the initial rainwater enters the abandonment well 1 from the water inlet pipe 2, the first floating ball 6 gradually floats up, the abandonment hole 51 is opened, and the subsequent rainwater passes through the abandonment hole 51 and the abandonment flow in sequence. After the pipe 4 is discharged, the initial rainwater abandonment begins to be realized; because the diameter of the abandonment pipe 4 is smaller than the diameter of the water inlet pipe 2, the water level in the abandonment well 1 will become higher and higher, and the initial rainwater will still be abandoned. Next, the first floating ball 6 will rise with the second floating ball until it blocks the jettison hole 51, completing the initial rainwater jettison flow; the subsequent rainwater will be discharged from the drain pipe 3, and finally enter the subsequent collection device to be collected.

In this paper, specific examples are used to illustrate the principle and implementation of the utility model, and the descriptions of the above examples are only used to help understand the method and core idea of the utility model. The above is only a preferred embodiment of the utility model, it should be pointed out that due to the limitation of literal expression, objectively there are infinite specific structures, for those of ordinary skill in the art, without departing from the principle of the utility model Under the premise, some improvements, modifications or changes can also be made, and the above-mentioned technical features can also be combined in an appropriate way; these improvements, modifications, changes or combinations, or the idea and technical solution of the invention can be directly applied to the In other occasions, all should be regarded as the protection scope of the present utility model.
