Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in fig. 1-2, the present embodiment provides a rainwater storage tank convenient for washing sediment, which includes a rainwater tank 1, a water storage tank 2, a drainage tank 3, a front gate 4, a rear gate 5, a controller and a flushing pipeline. Rainwater box 1, water storage box 2 and water drainage tank 3 communicate in proper order, and the size that technical personnel in the field can set up rainwater box 1, water storage box 2 and water drainage tank 3 according to actual need. The first end of the rain water tank 1 is communicated with the outside, and the water level in the rain water tank 1 is as high as the outside. Preceding gate 4 is fixed in between the second end of rainwater case 1 and the first end of water storage box 2, and back gate 5 is fixed in between the second end of water storage box 2 and the first end of drain box 3, and preceding gate 4 all uses current electric gate with back gate 5, and preceding gate 4 all is connected with the controller electricity with back gate 5, can remote control preceding gate 4 and back gate 5's switch through the controller. The second end of the drainage box 3 is provided with a water outlet which is used for discharging the sewage in the drainage box 3. The flushing pipeline is fixed in the water storage tank 2, an included angle is formed between an outlet of the flushing pipeline and the bottom of the water storage tank 2, and the flushing pipeline is arranged to enable water flow to flush the bottom of the water storage tank 2 at a certain angle.

During the use, when rainstorm takes place for the first time, preceding gate 4 is in the open mode, and the pipeline that erodees and back gate 5 of water storage box 2 bottom are closed, wait for the rainstorm and close preceding gate 4 after stopping, open back gate 5, empty water storage box 2, keep the water level after the rainstorm for the first time ends in the rainwater tank 1 this moment. If the water storage tank 2 is full and the rainstorm is not stopped, the rear gate 5 is opened, and the overflow is discharged through the water outlet. When the second rainstorm occurs, the water in the rainwater tank 1 rises to a certain height, and the water is ensured to have larger potential energy. Open the pipeline that erodees of water storage box 2 bottom in proper order, the action of preceding gate 4 and back gate 5 (erode the pipeline, the interval time of opening of preceding gate 4 and back gate 5 can be according to actual conditions, like the length of water storage box 2, factors such as the length thickness of size and pipeline set up the time delay, in order to ensure to erode the pipeline and can keep great pressure, it washes to the mud of bottom in the water storage box 2 to erode the pipeline, the rainwater that comes from in the rainwater box 1 carries out the level to wash to the bed mud in the water storage box 2, and then the realization is washed the water storage box 2 bottom in two ways. After the flushing is finished, the front gate 4 is opened, and the rear gate 5 is closed to store the rainstorm. And draining water after the rainstorm is finished. Therefore, when rainstorm comes each time and the water storage tank 2 stores water, sludge accumulated in the rainstorm of the last time can be efficiently washed. And after the flushing is finished, waiting for next water storage.

In order to increase the flushing effect of the flushing line, in this embodiment the outlet of the flushing line is perpendicular to the bottom of the reservoir 2. The arrangement makes the scouring effect good, when in use, the sludge is vertically impacted to be raised, so that the contact area of the sediment and the bottom of the tank is reduced, and the friction force is reduced. Thereby facilitating the rainwater from the rainwater tank 1 to wash it away.

Furthermore, in this embodiment, the flushing pipeline includes water supply pipeline 7 and a plurality of flushing pipes 6, the water source is connected to the first end of water supply pipeline 7, and the first end of a plurality of flushing pipes 6 is connected with the second end of water supply pipeline 7, and promptly flushing pipe 6 is a plurality of branches of water supply pipeline 7, and a plurality of flushing pipes 6 distribute along the quincuncial pile type, and the skilled person in the art can also adjust the number and the distribution of flushing pipes 6 according to actual need. The second end of the flushing pipe 6 is fixed at the bottom of the water storage tank 2, and the second end of the flushing pipe 6 is communicated with the inside of the water storage tank 2. The water in the flushing pipe 6 is used for dispersing the sediment in the water storage tank 2 from bottom to top.

In order to control the water flow in the water supply pipeline 7, in this embodiment, the water supply electric valve is disposed on the water supply pipeline 7, and the water supply electric valve is electrically connected to the controller. Thus, the remote control of the operator can be realized.

In order to detect the water level height in the rainwater tank 1 in real time, the embodiment further includes a water level sensor 9, the water level sensor 9 is an isolated diffused silicon sensing element or a ceramic capacitance pressure sensing sensor, the water level sensor 9 is fixed in the rainwater tank 1, and the water level sensor 9 is electrically connected with the controller. When storing the water that has higher flood peak in rainwater case 1, open the switch of water supply motorised valve, wash by water in the bottom, the ascending impact force of bath production will make the sediment local uplift that receives the impact, and the internal force between the sediment transmits the impact force to sediment around to make the sediment in water storage box 2 not hard up, conveniently wash away.

In this embodiment, the top height of rainwater tank 1, water storage tank 2 and drainage box 3 is parallel and level mutually, and rainwater tank 1 is parallel and level with the bottom of water storage tank 2, and drainage box 3's bottom is less than the bottom of water storage tank 2. The effect that sets up like this can effectual water conservancy diversion, with rainwater water conservancy diversion in the water storage box 2 to the drainage box 3 in to can increase the volume in the drainage box 3.

In order to facilitate the regular inspection and maintenance of workers, the present embodiment further comprises a manhole 10, and the manhole 10 is located at the top of the water storage tank 2. When workers are required to perform detection or maintenance, water in the water storage tank 2 is drained firstly, and then the workers enter the manhole 10.

When the place inconvenient to excrete waste water, can also set up outer discharge pipe way 8, the first end and the delivery port of outer discharge pipe way 8 in this embodiment are linked together, are equipped with outer discharge motorised valve on the outer discharge pipe way 8, and outer discharge motorised valve is connected with the controller electricity, through the switch of controller control outer discharge pipe way 8. The second end of the outward discharge pipe 8 can be connected to a device for discharging waste water according to actual needs by those skilled in the art.
