Background

The rain and sewage diversion intercepting well is one of the means with quick effect and good effect in the current water environment treatment and improvement measures, the private sunlight room problem often occurs on the roofs of old community buildings, domestic sewage generated by the activities of residents on the roofs is directly discharged to the roofs, the sewage is indirectly discharged into a rainwater vertical pipe along a rainwater gutter, even the resident directly connects the domestic sewage of the sunlight room with the rainwater vertical pipe, and the rain and sewage mixed connection problem exists in the rainwater system of the diversion community.

During dry seasons, domestic sewage generated by the roof is conveyed to a rainwater system of a community along with a rainwater vertical pipe, and then is discharged into a surrounding river system, so that the water body is polluted and the water ecological system is damaged.

When in rainy season, the roof has domestic sewage and rainwater, the mixed sewage is directly discharged into a river channel, in the rain and sewage diversion modification project process, the improvement difficulty coefficient of rain and sewage mixed connection problem caused by private construction of a sunlight room on the roof, especially on high floors (more than 7 floors), is found to be large, the parapet wall on the roof is required to be destroyed to thoroughly divert the sewage on the roof to the sewage vertical pipe on the building facade, but the life safety of high-altitude operators is not good, the destroyed building structure has large disturbance to residents, direct roof-removing diversion modification is not suggested, and a cut-off well is additionally arranged at the bottom of the rainwater vertical pipe which is in mixed connection with the building, so that the sewage and the rainwater are separated from the source, and the pollution degree to the surrounding water environment is reduced as much as possible.

In the existing intercepting well, an electric device or a hydraulic device is generally used for intercepting, and because sewage flows in the intercepting well for a long time, electric or hydraulic equipment used in the sewage can frequently break down, and general electric or hydraulic equipment can be blocked by sundries to cause water leakage, so that the electric or hydraulic device has poor sealing performance and is inconvenient to maintain in later period. Accordingly, the present inventors have developed a rain and sewage diversion intercepting well that automatically controls diversion using buoyancy and leverage.

The well 100 in this embodiment is arranged in a square configuration. Specifically, due to the drought season, the pipe diameter of the sewage drain pipe 120 is smaller than that of the rainwater drain pipe 130, because the sewage flow rate is far smaller than that in the rainy season, the cost saving effect is achieved.

The well body 100 is provided with a working chamber 100a inside, and the well body 100 is also provided with a shut-off weir 200 dividing the working chamber 100a into two and allowing sewage and separation. The cutoff weir 200 in the present embodiment divides the working chamber 100a into a sewage working chamber and a rainwater working chamber.

The inner wall of the well body 100 is provided with a fixed rod 300, a connecting rod 310 is rotatably connected to the fixed rod 300, and two ends of the connecting rod 310 are respectively connected with a flashboard 400 and a pontoon assembly 500 which are arranged in the working chamber 100 a. The fixing rod 300 in this embodiment is rotatably connected to the connecting rod 310 through a rotation shaft 301, so that the connecting rod 310 swings up and down.

The pontoon assembly 500 includes a pontoon groove 510 provided inside the well body 100 at the rear end of the cutoff weir 200, and a hollow pontoon 520 provided in the pontoon groove 510, the hollow pontoon 520 being connected to the connecting rod 310 by a first connection member a. The first connection member a in this embodiment is preferably a first thin wire. Specifically, the diameter of the pontoon 520 is slightly smaller than the pontoon groove 510 and the depth of the pontoon groove 510 is equal to the height of the pontoon 520 and the diameter of the sewage drain pipe 120.

The hollow pontoon 520 is provided with a filter net 521 for preventing foreign substances from entering the pontoon groove 510. The filter 521 is detachably connected to the hollow pontoon 520, and the filter 521 can be opened to clean sediment in the pontoon groove 510, so that the filter 521 can prevent suspended solids from blocking the pontoon groove drain pipe 511 at the lower end during rainy season.

The bottom of the pontoon groove 510 is provided with a pontoon groove drain pipe 511 connected to a downstream rain manhole. Specifically, the diameter of the pontoon groove drain pipe 511 is smaller than that of the rainwater drain pipe 130, and the pontoon groove drain pipe 511 is disposed at a height higher than the bottom of the well body 100, like a sediment tank, to prevent sediment from clogging the downstream drain pipe.

The shutter 400 is movably connected with a shutter catching groove 410 provided on the sewage drain pipe 120, and the shutter 400 is connected with the link 310 through a second connection member b. The second connecting member b in this embodiment is preferably a second thin wire.

In order to prevent the sewage in the sewage drain pipe 120 from overflowing to enter the rainwater drain pipe 130, the pipe diameter of the sewage drain pipe 120 in this embodiment is lower than the weir height of the intercepting weir 200.

The working principle of the utility model is as follows:

when the mass of the pontoon 520 is larger than that of the flashboard 400 in dry season, the flashboard 400 in the flashboard clamping groove 410 is in the highest state, namely the sewage drain pipe 120 is in the open state, the position of the hollow pontoon 520 in the pontoon groove 510 is in the lowest state, sewage enters the well body 100 from the confluent water inlet pipe 1, and the front end of the interception weir 200 flows into the sewage drain pipe 120 due to smaller sewage flow;

when rainy season, a large amount of rainwater flows into the well body 100 through the confluence water inlet pipe 110, passes through the interception weir 200, enters the pontoon groove 510 through the filter screen 521, floats upwards under the action of the buoyancy and the connecting rod 310, so that the flashboard 400 descends in the flashboard clamping groove 410, at the moment, the sewage water drain pipe 120 is in a closed state, a large amount of rainwater enters the rainwater water drain pipe 130, after the rainfall is finished, the rainwater in the pontoon groove 510 leaks to a downstream rainwater inspection well through the pontoon groove water drain pipe 511, at the moment, the water level descends, the pontoon 520 descends to restore to original state, and the flashboard 400 automatically ascends to restore to an original state to be in an open state.
