Rainwater storage tank ejection-type flushing device, control method and rainwater storage tank

Abstract

The invention discloses a rainwater storage tank ejection-type flushing device, a control method and a rainwater storage tank. The rainwater storage tank ejection-type flushing device comprises a power pump and a rotating driver, the power pump is arranged in a water collection pit and used for delivering rainwater in the water collection pit into an ejection pipe to be ejected onto the second surface of the rainwater storage tank to flush the same, and the rotating driver is used for driving the ejection pipe to rotate in the rainwater storage tank. The flushing device can utilize the power pump to extract water in the water collection pit to vigorously flush the bottom in the rainwater storage tank when sewage in the rainwater storage tank is about to be drained. In the process of ejection-type flushing, the ejection pipe can rotate within a range of 0-260 degrees (namely being adjustable), in other words, the ejection pipe can rotate underwater to eject water flow, so that the flushing device is wide in flushing range, and the bottom of the rainwater storage tank can be cleaned in an omnibearing manner and can be flushed more cleanly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a jet-type flushing device for a rainwater storage tank, a control method and the rainwater storage tank. Background technique [0002] When a city receives rain, it tends to increase runoff, and rainwater and sewage often converge, increasing the burden on urban drainage and sewage pipe networks. Direct discharge into natural water bodies will cause serious pollution to the water body environment. Therefore, it is necessary to add rainwater storage tanks and other facilities to regulate and treat rainwater with different water qualities. In my country's urban drainage system, the application of rainwater storage tanks is becoming more and more extensive. [0003] However, after the initial rainwater entering the rainwater storage tank has been stored for a period of time, a large amount of sediment will be deposited on the bottom of the tank. After the sewage is emptie...

Problems solved by technology

[0003] However, after the initial rainwater entering the rainwater storage tank has been stored for a period of time, a large amount of sediment will be deposited on the bottom of the tank. After the sewage is emptied, the bottom of the tank must be washed clean in time, otherwise, once the sediment on the bottom of the tank is compacted, it will be difficult to clear

In the prior art, water pipes are generally used on the ground to flush the bottom of the rainwater storage tank, but this flushing method requires the use of water pipes to reintroduce the water source to flush the bottom of the pool, and the second is to flush the bottom of the pond on the ground , time-consuming and labor-intensive and the cleanliness is not high

Moreover, during the flushing process, due to the high distance between the water pipe and the bottom of the pool, it is easy to produce dead angles during flushing, and the bottom of the rainwater storage tank cannot be rinsed clean.
