Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The purpose of the present invention is to provide a rainwater storage tank that is convenient for flushing sediments, which is used to solve the technical problems existing in the above-mentioned prior art. The bottom of the tank is flushed in two directions at the same time, and the sedimentary pollutants can be effectively washed away.

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1-2, this embodiment provides a rainwater storage tank for flushing sediments, including a rainwater tank 1, a water storage tank 2, a drainage tank 3, a front gate 4, a rear gate 5, a controller and flush piping. The rainwater tank 1 , the water storage tank 2 and the drainage tank 3 are connected in sequence, and those skilled in the art can set the sizes of the rainwater tank 1 , the water storage tank 2 and the drainage tank 3 according to actual needs. The first end of the rainwater tank 1 is communicated with the outside world, and the water level in the rainwater tank 1 is the same height as the outside world. The front gate 4 is fixed between the second end of the rainwater tank 1 and the first end of the water storage tank 2, and the rear gate 5 is fixed between the second end of the water storage tank 2 and the first end of the drainage tank 3. The front gate 4 and the rear gate 5 both use existing electric gates, and both the front gate 4 and the rear gate 5 are electrically connected to the controller, and the switches of the front gate 4 and the rear gate 5 can be remotely controlled by the controller. The second end of the drainage tank 3 has a water outlet, and the water outlet is used to discharge the sewage in the drainage tank 3 . The flushing pipeline is fixed in the water storage tank 2, and the outlet of the flushing pipeline has an included angle with the bottom of the water storage tank 2, so that the water flow can flush the bottom of the water storage tank 2 at a certain angle.

When in use, when the first rainstorm occurs, the front gate 4 is open, the flushing pipeline at the bottom of the water storage tank 2 and the rear gate 5 are closed, wait for the rainstorm to stop, close the front gate 4, open the rear gate 5, and empty the water storage. Tank 2, at this time, the water level in the rainwater tank 1 after the end of the first rainstorm is maintained. If the water storage tank 2 is full and the rainstorm has not stopped, the rear gate 5 is opened, and the overflow is discharged through the water outlet. When the second rainstorm occurs, wait for the water in the rainwater tank 1 to rise to a certain height, which ensures that the water has greater potential energy. The actions of sequentially opening the flushing pipeline at the bottom of the water storage tank 2, the front gate 4 and the rear gate 5 (the opening interval of the flushing pipeline, the front gate 4 and the rear gate 5 can be based on the actual situation, such as the length of the storage tank 2, the The time delay is set for factors such as the size and the length and thickness of the pipeline to ensure that the flushing pipeline can maintain a large pressure). The bottom mud in the tank 2 is flushed horizontally, thereby realizing two-way flushing of the bottom of the water storage tank 2 . After the flushing is completed, the front gate 4 is opened, and the rear gate 5 is closed to store water for this rainstorm. The water will be drained after the rainstorm is over. In this way, every time the rainstorm comes, the water storage tank 2 will efficiently flush the sludge accumulated in the previous rainstorm when the water storage tank 2 stores water. After flushing, wait for the next water storage.

In order to improve the flushing effect of the flushing pipeline, in this embodiment, the outlet of the flushing pipeline is perpendicular to the bottom of the water storage tank 2 . This arrangement makes the scouring effect good. When in use, the sludge is vertically impacted to make the sludge rise, thus reducing the contact area between the sediment and the bottom of the box and reducing the frictional force. Thereby it is facilitated to be washed away by the rainwater from the rainwater tank 1 .

Further, in this embodiment, the flushing pipeline includes a water supply pipeline 7 and a plurality of flushing pipes 6 , the first end of the water supply pipeline 7 is connected to the water source, and the first ends of the multiple flushing pipes 6 are connected with the first The two ends are connected, that is, the flushing pipe 6 is a plurality of branches of the water supply pipeline 7, and the plurality of flushing pipes 6 are distributed along the plum blossom pile shape.

The water level sensor 9 is electrically connected with the controller. When the rainwater tank 1 is filled with water with a high water head, open the switch of the electric water supply valve and flush the water at the bottom. The upward impact force generated by the flushing will cause the impacted bottom mud to partially bulge, and the internal force between the bottom mud will rise. The impact force is transmitted to the surrounding bottom mud, so that the bottom mud in the water storage tank 2 is loosened and washed away easily.

In this embodiment, the tops of the rainwater tank 1, the water storage tank 2 and the drainage tank 3 are at the same height, the bottoms of the rainwater tank 1 and the water storage tank 2 are flush, and the bottom of the drainage tank 3 is lower than the height of the water storage tank 2. bottom. The function of this arrangement can effectively guide the flow, guide the rainwater in the water storage tank 2 to the drainage tank 3, and can increase the volume of the drainage tank 3.
