Problems solved by technology

However, the long-term accumulation of sediment in the storage tank can easily form a large amount of silt or even compaction.
Once these silt and compaction are formed, it is difficult to be washed away by traditional washing equipment

[0037] see in conjunction figure 1 and figure 2 As shown, according to the first embodiment of the present invention, the mixing device includes an injector 11, which is arranged in the sump 2, and the nozzle of the injector 11 faces the side of the storage tank 1 away from the sump 2. When it rains, the rainwater is stored in the storage tank 1 . After the rainwater is stored in the storage tank 1 for a certain period of time, the control system controls the injector 11 to periodically stir the rainwater in the storage tank 1 to prevent the formation of silt and hardened objects at the bottom of the storage tank 1 . After the rainfall ends, the control system controls the submersible sewage pump 3 to pump the rainwater in the storage tank 1 into the sewage treatment plant; when the liquid level gauge 10 senses that the liquid level in the storage tank 1 drops, it transmits the signal to the control system to control The system controls the ejector 11 to stir the rainwater ...

Abstract

The invention discloses a rainwater regulation and storage device. The rainwater regulation and storage device comprises a regulation and storage pool, as well as a stirring device and a flushing device which are arranged in the regulation and storage pool, wherein the stirring device is used for stirring rainwater in the regulation and storage pool, the flushing device is used for flushing the bottom of the regulation and storage pool, a water collecting pit is formed in the bottom of one side of the regulation and storage pool, and a submersible sewage pump is arranged in the water collecting pit. For the rainwater regulation and storage device, the phenomenon that sediment forms sludge and hardened matters at the bottom of the regulation and storage pool can be effectively avoided, so that the regulation and storage effects of the rainwater regulation and storage device are ensured.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage systems, in particular to a rainwater regulation and storage device. 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, so it is necessary to add facilities such as primary rain storage tanks to regulate rainwater of different water quality. In the urban drainage system of our country, the application of primary rain storage tanks is becoming more and more extensive, and flushing devices are generally installed in the primary rain storage tanks. [0003] Installing a flushing device in the storage tank can wash away the sediment at the bottom of the storage tank, preventing the sediment from accumulating in the storage tank and causing th...
