Description

Rainwater discarding device capable of being automatically opened and closed according to liquid level

Technical Field

The utility model relates to a rainwater utilization device, in particular to a class device is abandoned to rainwater according to liquid level automatic opening and closing.

Background

In recent years, as the situation of water resource shortage is gradually emphasized, rainwater recycling measures have been widely applied in the engineering range. In the early stage of rainfall, a large amount of atmospheric pollutants are dissolved in the early rain water due to the automobile exhaust, dust and the like contained in the air. When the rainwater reaches the ground, the ground runoff can scour buildings, roads and the like and carry pollutants such as ground silt, organic matters, grease and the like, so that the initial rainwater is high in pollution degree, and part of the initial rainwater exceeds the pollution degree of urban sewage and is not suitable for recycling. And with the continuous rainfall, the pollutants in the rainwater in the middle and later periods are less. Therefore, the rainwater in the middle and later periods is fully utilized, and the water quality control measure is effective for the initial rainfall abandon. The current rainwater discarding modes commonly used at present mainly include two types: velocity-type reject flow and volumetric reject flow.

The design idea of the speed type flow discarding method is that the flow velocity is small in the early stage of rainfall, the flow velocity is large in the middle and later stages of rainfall, initial rainwater is discharged into the flow discarding pipes according to different flow velocities, and clean rainwater in the middle and later stages is discharged into a rainwater collecting pipe to be recycled. However, the system is only used for general conditions, and the device cannot achieve the design purpose under the conditions that the instantaneous rainstorm intensity is large or the rainfall lasts for a long time but the instantaneous rainstorm intensity is always small.

The initial rainwater storage volume is calculated according to the rainwater discarding thickness and the catchment area by the positive displacement discarding method, and when the rainfall exceeds the storage volume of the initial rainwater pool body, the subsequent rainwater enters the rainwater collection system. However, the opening and closing mode of the waste flow pipe in actual operation has the problems that: when the abandoning pipe is manually opened and closed, the abandoning pipe valve needs to be manually closed at the early stage of rainfall after entering the well body, and the abandoning pipe valve is opened after the rainfall is finished, so that the labor is wasted, the working risk exists, when the abandoning pipe is controlled by the electromagnetic valve, the parameters need to be manually set, and once the valve is damaged, the maintenance is inconvenient and the price is high.

In fig. 2, the position of the square frame marked by the thick black solid line corresponds to the position of the choke plug 5 when the choke plug 5 closes the waste flow pipe 6, and the circle marked by D1 corresponds to the position of the orifice of the waste flow pipe 6, so that when the choke plug 5 is positioned at the bottom of the slide rail 4, the waste flow pipe 6 is blocked and cannot be drained outwards; after the plug 5 is lifted to the position D2, the opening of the waste pipe 6 is opened, and normal drainage can be realized. In the abandoning well, a water inlet pipe 7 is deployed above, a abandoning pipe 6 is deployed at the bottom of the well, and a collecting pipe 8 is deployed at the middle position.

Further, the density of the floating body 1 is less than that of water; the connecting rod 3 takes the rotating shaft 2 as a fulcrum to form a lever structure, the end where the floating body 1 is located is a resistance arm of which the length of a power arm is larger than that of a plug, and the product of the weight of the floating body 1 and the length of the power arm is larger than that of the plug.

Furthermore, the flow abandoning pipe 6 is fixed along the horizontal direction and is clung to the slide way 4, the slide way 4 is perpendicular to the flow abandoning pipe 6, and forms an L-shaped water outlet structure together with the flow abandoning pipe 6.

Furthermore, the water outlet section of the slide way 4 adopts a porous net structure, and the net structure can block sundries with larger sizes and prevent the flow abandoning pipe 6 from being blocked.

Further, the plug 5 is arranged in the slide way and moves along the vertical direction, and the width of the plug 5 is larger than the diameter of the flow discharge pipe 6 and smaller than the width of the slide way 4; the length of the plug 5 is larger than the diameter of the flow discharge pipe 6 and is less than half of the length of the slide 4.

The principle and the using method of the utility model are as follows:

at the initial stage of rainfall, because the lever self that connecting rod 3 formed is uneven, body place end can sink to body 1 is in the low point, and through connecting rod 3's effect, end cap 5 is located slide rail 4 tops, and the rainwater is discharged from abandoning the flow tube, and along with rainfall increases, abandons the internal liquid level of flow well and rises, and body 1 floats up gradually, and flow tube 6 is abandoned in the shutoff of control end cap 5 gradually, abandons the internal rainwater of flow well and passes through rainwater collecting pipe 8 and discharge. After the rainfall stops, the rainwater collecting pipe 8 continues to discharge the rainwater, so that the water level is reduced, the position of the floating body 1 is reduced, the plug 5 in the slide way 4 gradually rises, the rainwater is discharged out of the well body from the flow discarding pipe 6, and the function of automatically opening and closing the liquid level control is realized.
