Detailed Description

The present utility model will be described in detail below with reference to the accompanying drawings and examples.

The utility model provides a rain sewage diversion structure, as shown in figures 1-5, includes drain box 1, sets up into dirty pipe 2, income rain hole 3, blow off pipe 4 and the drainage pipe 5 on drain box 1. Wherein the drainage box 1 is a box body for sewage transfer and rainwater collection, and when no rain falls, the sewage is conveyed into the drainage box 1 by the sewage inlet pipe 2 through the sewage outlet pipe 4 and is discharged out of the drainage box 1 through the sewage outlet pipe 4; after raining, the rain drain pipe 5 will recycle the rainwater collected by the drain box 1 and split the rainwater with sewage to reduce the pollution of the rainwater.

Outside rainwater enters the drainage box 1 through the rainwater inlet holes 3 after being gathered, so that the rainwater is recovered; the drainage box 1 is internally provided with a diversion part and a control device for controlling the diversion part to change, after the outside rains and a certain precipitation amount is accumulated, rainwater enters the inner wall of the drainage box 1 from a rain inlet 3 and is accumulated on a liquid storage table 11, a floating ball 12 in the control device is arranged on the upper side of the liquid storage table 11, and the change of the liquid height in the liquid storage table 11 can be rapidly sensed by utilizing the low-density floating ball 12 and can float and sink along with the change of the liquid level; the linkage assembly can be triggered in the rising process of the floating ball 12, so that the linkage assembly drives the diversion piece to change, the drainage box 1 can divert rainwater into the drainage pipe 5, separation treatment of the rainwater and the sewage is ensured, rainwater pollution is reduced, and the recovery rate and the reuse rate of the rainwater are improved.

As shown in fig. 2-4, when the floating ball 12 moves upwards, the linkage shaft 13 connected with the floating ball 12 in the linkage assembly rotates under the buoyancy of the floating ball 12, the upward movement of the linkage shaft 13 near one end of the floating ball 12 causes the linkage shaft 13 to move downwards away from one end of the floating ball 12 and push the button 14, the electromagnetic block 15 at the lower side after the button 14 is pressed downwards generates magnetic force to attract the adsorption block, at this time, the movable plate 6 fixedly connected with the adsorption block moves to separate the movable plate 6 from the fixed plate 7, at this time, the first groove 8 and the second groove 9 on the movable plate 6 and the fixed plate 7 are exposed to enable rainwater to flow downwards into the rainwater drainage pipe 5 smoothly, at this time, the rainwater can flow downwards through the first groove 8 and the second groove 9 and be drained from the rainwater drainage pipe, and sewage is conducted downwards to the sewage drainage pipe 4 between the sewage inlet pipe 2 and the connecting pipe 10 to realize the diversion of rainwater and sewage; the first grooves 8 on the surface of the moving plate 6 can also play a role in blocking sundries to a certain extent, and impurities in rainwater are reduced.

When the external rainwater is overlarge, the rainwater drainage speed of the rainwater drainage pipe 5 is lower than the liquid inlet speed of the box body, the rainwater surface in the drainage box 1 is lifted, when the rainwater surface is higher than the top surface of the movable plate 6, the part is also higher than the position of the connecting pipe 10, and the rainwater higher than the part of the movable plate 6 is drained from the sewage drainage pipe 4 under the driving of gravity, so that the phenomenon that the rainwater is excessively stored and cannot be timely drained to overflow the drainage box 1 under the environment of overlarge rainfall is avoided; the sewage inlet pipe 2 is communicated into the connecting pipe 10, and the diameter of the connecting pipe 10 is larger than that of the sewage inlet pipe 2, so that the connecting pipe 10 can receive sewage and simultaneously receive rainwater higher than the moving plate 6.

As shown in fig. 2-5, when the fixed plate 7 and the movable plate 6 are attached, the first grooves 8 and the second grooves 9 which are arranged in a staggered manner on the two plates are closed, so that sewage is prevented from entering the rain drain pipe 5 to pollute the recovered rainwater.

Further setting, through the form of lug seal recess between fixed plate 7 and movable plate 6 both, guarantee that liquid can't get into in the rainwater drainage pipe 5 when fixed plate 7 and movable plate 6 laminating state, in the time, the setting of lug can also make the liquid that can't the low flow be in movable plate 6 upside, makes things convenient for unnecessary liquid to receive from connecting pipe 10 and removes to blow off pipe 4, avoids part sewage to overflow back pollution rainwater storage from connecting pipe 10.

As shown in fig. 2-4, the bottom end of the liquid storage table 11 is provided with a flow channel, so that the liquid stored in the inner side can be slowly drained to the lower side, and the floating ball 12 on the liquid storage table 11 is prevented from being kept in an upward floating state all the time, so that the moving plate 6 and the fixed plate 7 are kept in a separated state; the throttle valve 16 can control the flow rate of the liquid in the flow channel, and can prevent the liquid stored in the liquid storage table 11 from being discharged downwards too fast and too slow after being arranged.

After rainwater does not enter the upper side of the liquid storage table 11 and internal liquid is discharged to a proper position, the floating ball 12 lowers along with the lowering of the water surface in the liquid storage table 11, at this time, the linkage shaft 13 rotates under the gravity drive of the floating ball 12, so that the pressure born by the upper side of the button 14 disappears to automatically reset, the electromagnetic block 15 is powered off after the button 14 resets, and the movable plate 6 approaches the fixed plate 7 under the self gravity and is attached to the fixed plate 7.

As shown in fig. 1-4, the cross-sectional area of the liquid storage platform 11 is larger than the largest area of distribution of the water inlet holes, so that after the arrangement, the liquid in the drainage box 1 enters the liquid storage platform 11 from the water inlet holes 3, and after the storage platform 11 finishes rainwater accumulation, the surplus rainwater falls from the liquid storage platform 11 to one side of the drainage pipe 5 to be close to; after the arrangement, the starting time of the movable plate 6 can be shortened, and the recovery rate of rainwater is further improved; meanwhile, the distance between the two sides of the liquid storage table 11 and the drain box 1 can enable rainwater to flow downwards from multiple directions after liquid accumulation on the liquid storage table 11 is completed, and the downflow speed of the rainwater is improved.

As shown in fig. 1, the rain inlet holes 3 are formed at two ends of the drainage box 1, and can be used for simultaneously recovering rainwater from two side surfaces after being split at the upper side of the drainage box 1, so that the recovery efficiency of the rainwater is improved.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
