Description

TECHNICAL FIELD

[0001] The present application relates to the field of rainwater storage tank, in particular to a high-efficiency and environment-friendly rainwater storage tank. BACKGROUND

[0002] When the city is raining, the runoff is often increased, and rainwater and sewage often converge, increasing the burden of the urban drainage network and sewage network. Especially in the early stage of rainfall, the initial rain contains a large amount of pollutants, and if the initial rain is directly discharged into the natural water body, it will cause serious pollution to the water environment, so it is necessary to add rainwater storage tank and other facilities to adjust and treat rainwater of different water quality. In the urban drainage system in China, rainwater storage tanks are increasingly widely used.

[0003] However, after the initial rainwater entering the rainwater storage tank is stored for a period of time, a large amount of sediment will be deposited at the bottom of the tank, and the bottom of the tank needs to be cleaned in time after the sewage is discharged. In the prior art, a water pipe is generally used on the ground to flush the bottom of the rainwater storage tank, but this flushing method has two problems: first, a water pipe needs to be used to introduce water source again to flush the bottom of the tank, and second, the bottom of the tank is flushed on the ground, which is time-consuming and laborious and has low cleanliness. In addition, during the flushing process, due to the high distance between the water pipe and the bottom of the tank, dead angles are easily generated during flushing, the bottom of the rainwater storage tank cannot be flushed clean, and the deposited sediment at the bottom of the tank will be very difficult to remove after being hardened. SUMMARY

[0004] In order to clean the rainwater storage tank, the present application provides a high-efficiency and environment-friendly rainwater storage tank.

[0005] The high-efficiency and environment-friendly rainwater storage tank provided by the present application adopts the following technical solution:

[0006] A high-efficiency and environment-friendly rainwater storage tank, comprising a tank body, a water storage chamber, a baffle door and a cleaning assembly, the tank body is provided with a flushing port, the water storage chamber is connected to the tank body, the water storage chamber is provided with a containing cavity, the containing cavity is communicated with the flushing port, the baffle door is rotationally connected to the tank body and is used for covering the flushing port, and the cleaning assembly comprises a cleaning shovel, one end of the cleaning shovel is slidingly connected to the tank body, and the other end of the cleaning shovel abuts against the bottom surface of the tank body.

[0007] By using the above technical solution, before flushing the bottom of the storage tank, the deposited sediment hardened at the bottom is removed by using the cleaning shovel, and then the storage tank is washed, so that the rainwater storage tank can be easily cleaned.

[0008] Preferably, the cleaning shovel is provided with a cleaning surface, and an included angle between the cleaning surface and the bottom surface of the tank body is an obtuse angle.

[0009] By using the above technical solution, the cleaning surface is an inclined surface, which is convenient for removing the deposited sediment hardened at the bottom of the tank.

[0010] Preferably, the cleaning assembly further includes a connecting rod, the upper end of which is slidably connected to the pool body and the sliding direction of the connecting rod is horizontal. The upper end of the cleaning shovel is slidably connected to the connecting rod and the sliding direction of the cleaning shovel is vertical.

[0011] By adopting the above-mentioned technical solution, the vertical sliding of the cleaning shovel allows it to contact the bottom surface of the pool, while the horizontal sliding of the connecting rod drives the cleaning shovel to remove the hardened sediment at the bottom of the pool, facilitating the cleaning of the bottom surface of the pool.

[0012] Preferably, the cleaning assembly further includes a spring, the lower end of the connecting rod is provided with a mounting groove, the spring is disposed in the mounting groove, the upper end of the cleaning shovel is embedded in the mounting groove, one end of the spring is connected to the bottom of the mounting groove, and the other end of the spring is connected to the upper end of the cleaning shovel.

[0013] By adopting the above technical solution, the spring ensures that the cleaning shovel always contacts the bottom surface of the pool during the sliding process, making it easier to clean the hardened material deposited at the bottom of the pool.

[0014] Preferably, it further includes a rotating shaft, a gear, and a rack. The rotating shaft is rotatably connected to the pool body, the baffle is connected to the rotating shaft, the gear is sleeved on the outer circumference of the rotating shaft, the rack is slidably connected to the pool body, the gear meshes with the rack, the sliding direction of the rack is perpendicular to the rotation axis of the rotating shaft, and the cleaning shovel is connected to the rack.

[0015] By adopting the above technical solution, the rotating shaft drives the baffle to rotate, the flushing port opens to release water from the water storage chamber to clean the pool. The rotating shaft drives the gear to rotate, causing the rack to slide. During the sliding of the rack, it drives the cleaning shovel to clean the hardened material at the bottom of the pool.

[0016] Preferably, it also includes a pull rope, one end of which is wound around the outer circumference of the rotating shaft, and the other end of which is connected to the end of the baffle door away from the water storage chamber.

[0017] By adopting the above technical solution, the rotation of the shaft causes the rope to shorten and pull up the gate, opening the flushing port to release water from the water storage chamber to clean the pool. The use of the pull rope makes it easy to control the opening and closing of the gate.

[0018] Preferably, the height of the bottom surface of the pool decreases as it moves away from the barrier.

[0019] By adopting the above technical solution, it is easy to drain the water released from the gate and to clean the bottom of the pool.

[0020] Preferably, the pool also includes a grating, wherein the pool body is provided with a water inlet, and the grating is connected to the outer wall of the pool body and covers the water inlet.

[0021] By adopting the above technical solution, the bar screen performs preliminary filtration of rainwater entering the reservoir, filtering out large floating objects and garbage, which facilitates the subsequent treatment of rainwater in the reservoir.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Before flushing the bottom of the stormwater storage tank, use a cleaning shovel to remove the hardened sediment at the bottom of the tank, and then drain the tank to clean it, so as to make it easier to clean the stormwater storage tank.

[0024] 2. The vertical sliding of the cleaning shovel allows it to contact the bottom of the pool, while the horizontal sliding of the connecting rod drives the cleaning shovel to remove the hardened sediment at the bottom of the pool, facilitating the cleaning of the bottom surface of the pool.

[0025] 3. The rotation of the shaft shortens the rope, pulling up the baffle gate and opening the flushing port to release water from the water storage chamber to clean the pool. The pull rope makes it easy to control the opening and closing of the baffle gate. Attached Figure Description

[0052] The implementation principle of a high-efficiency and environmentally friendly rainwater storage tank in this application embodiment is as follows: Rainwater collected on rainy days enters the feed pipe 21, is filtered by the screen 31, and flows into the distribution channel 1114 through the inlet 112. Due to the obstruction of the weir gate 41, the initial rainwater cannot enter the later storage chamber 1113. Instead, the initial rainwater enters the initial storage chamber 1111 through the inlet 112, causing the water level in the initial storage chamber 1111 to rise. This causes the float valve 42 to close the outlet 331. At this time, the rainwater flows to the later storage chamber 1113. After a period of time, the water level in the later storage chamber 1113 reaches the third outlet 118, thus storing the rainwater. Water is discharged into the river. Since the inner diameter of the third outlet 118 is smaller than the inner diameter of the feed pipe 21, the water level in the storage chamber 1113 will continue to rise. After the rain stops, the rainwater in the storage chamber 1111 will be discharged from the first outlet 116 to the sewage treatment center. The storage chamber 1113 will continue to release water until the water level drops below the height of the third outlet 118. At this time, the pump 84 will be started to pump the remaining rainwater into the receiving chamber 51. The drive cylinder 86 will drive the control door 87 to move upward and open the outlet 331. The drive motor will drive the rotating shaft 71 to rotate, so that the gate 6 can rotate and the cleaning component 8 can slide to clean the bottom of the pool.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
