Description

Technical Field

[0001] The present application relates to the technical field of sewage discharge, and more specifically, to a rainwater and sewage diversion device. Background Art

[0002] Rainwater and sewage diversion is a drainage system that separates rainwater and sewage, and transports them through a separate pipeline for discharge or subsequent treatment. Rainwater can be discharged directly into the river through the rainwater pipe network, and sewage needs to be collected through the sewage pipe network and sent to the sewage treatment plant for treatment. After the water quality reaches the corresponding national or local standards, it can be discharged into the river. This can prevent the river from being polluted. The Chinese utility model patent with publication number CN214833233U discloses a rainwater and sewage diversion device used on municipal roads. The above patent has the function of changing the weight of rainwater on the top of the driving mechanism to move the driving structure in the vertical direction, thereby driving the diversion plate to deflect, thereby achieving the effect of diverting rainwater and sewage. However, it cannot divert rainwater and sewage in a more detailed and accurate manner, which increases the cost of sewage treatment.

[0003] The document with the prior art publication number CN 220414432 U provides a rainwater and sewage diversion device, which realizes the synchronous switching of opening and closing of different internal pipes through the mutual cooperation of a first plug and a second plug, and has a good sealing effect, thereby reducing the cost of sewage treatment; through the buoyancy driving component, even if the rainfall is small, as long as a large amount of rainwater enters the overflow tank, the rainwater can increase the buoyancy of the floating block, and drive the connecting rod device to drive the plug device through the floating block; through the set connecting rod assembly, it is realized that the two groups of plugs are driven by the buoyancy block, and the lever principle is used to increase the effect of buoyancy to smoothly drive the plug device.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when heavy rainfall occurs, a large amount of debris blocks the filtering device, which will cause the water inlet of the water inlet pipe to decrease, thereby causing the first plug to be unable to be pushed due to insufficient rainwater. At the same time, when the rainfall is heavy, the single rainwater pipe cannot drain the rainwater quickly, which leads to a large amount of water accumulation.

[0005] In view of this, we propose a rainwater and sewage diversion device. Utility Model Content

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] A rainwater and sewage diversion device comprises: an inlet pipe 1, a rainwater pipe 2, a sewage pipe 3, a disc 4 and a coarse filter screen plate 5, the water inlet ends of the rainwater pipe 2 and the sewage pipe 3 are connected with the inlet pipe 1, the disc 4 is rotatably arranged in the inlet pipe 1, the coarse filter screen plate 5 is fixed in the inlet pipe 1, a first through hole 401 and a second through hole 402 and a third through hole 403 symmetrically arranged with the second through hole 402 are formed on the disc 4, and a stainless steel brush 406 in contact with the upper surface of the coarse filter screen plate 5 is drivingly connected to the disc 4.

[0033] Reference Figure 1-Figure 7The axes of the first through hole 401, the second through hole 402 and the third through hole 403 correspond to the axes of the rainwater pipe 2 and the sewage pipe 3. The sewage pipe 3 and the rainwater pipe 2 are symmetrically arranged. The coarse filter plate 5 is used to intercept large debris, and through the transmission of the disc 4 and the stainless steel brush 406, the stainless steel brush 406 rotates on the upper surface of the coarse filter plate 5 to clean the debris and avoid large-scale clogging of the coarse filter plate 5. At the same time, when discharging sewage, the disc 4 is rotated so that the first through hole 401 corresponds to and is connected with the sewage pipe 3. At this time The second through hole 402, the third through hole 403 and the rainwater pipe 2 are closed; when the rainwater pipe 2 discharges rainwater independently, the first through hole 401 corresponds to and is connected with the rainwater pipe 2. At this time, the second through hole 402, the third through hole 403 and the sewage pipe 3 are in a closed state. When the rainfall is heavy, the disc 4 is rotated so that the second through hole 402 corresponds to and is connected with the rainwater pipe 2, and the third through hole 403 corresponds to and is connected with the sewage pipe 3. At this time, the rainwater can be discharged through the rainwater pipe 2 and the sewage pipe 3 to avoid the problem of rainwater accumulation caused by heavy rainfall.

[0034] A servo motor 404 is fixedly installed between the rainwater pipe 2 and the sewage pipe 3. The servo motor 404 is transmission-connected to the disc 4. The disc 4 is coaxially fixed with a shaft 405 that passes through the coarse filter plate 5. The upper end of the shaft 405 is vertically fixed to the stainless steel brush 406.

[0035] Reference Figure 1 and Figure 7 The output shaft of the servo motor 404 is coaxially fixed with the lower end of the disc 4, so that the servo motor 404 drives the shaft 405 and the disc 4 to rotate, and when the shaft 405 rotates, it can drive the stainless steel brush 406 on the top to clean the upper surface of the coarse filter plate 5, avoiding the problem of poor drainage caused by large-scale accumulation of debris.

[0036] A liquid level sensor 6 is fixedly installed in the water inlet pipe 1 .

[0037] Reference Figure 1 The liquid level sensor 6 is used to monitor the water level in the water inlet pipe 1. When the internal water level rises and the rainwater is not discharged smoothly, the staff can adjust the rotation of the disc 4 to allow the sewage pipe 3 and the rainwater pipe 2 to drain together, so as to lower the water level in the water inlet pipe 1 and speed up the discharge of rainwater.

[0038] A fine filter screen plate 407 is fixedly installed in the first through hole 401 , the second through hole 402 and the third through hole 403 .

[0039] Reference Figure 7 , through the fine filter screen 407, so as to finely filter the rainwater or sewage entering the water inlet pipe 1.

[0040] The fine filter screen plate 407 is fixed to the lower ends of the first through hole 401 , the second through hole 402 and the third through hole 403 .

[0041] Reference Figure 7 The fine filter screen plate 407 is fixed at the lower end of the through hole, so that the through hole and the fine filter screen plate 407 form a filter cylinder to facilitate the accumulation of filtered matter, and finally facilitate the centralized cleaning of debris by maintenance personnel.

[0042] Working principle: when discharging sewage, the servo motor 404 drives the disc 4 to rotate, and makes the first through hole 401 correspond to and communicate with the sewage pipe 3, at which time the second through hole 402, the third through hole 403 and the rainwater pipe 2 are closed; when it rains, the servo motor 404 drives the disc 4 to rotate, and makes the first through hole 401 correspond to and communicate with the rainwater pipe 2, at which time the second through hole 402, the third through hole 403 and the sewage pipe 3 are in a closed state. During this process, the shaft 405 drives the stainless steel brush 406 to rotate, which can clean the upper surface of the coarse filter plate 5. After the liquid level sensor 6 monitors that the water level of the water inlet pipe 1 rises, the servo motor 404 is started to drive the disc 4 to rotate, and makes the second through hole 402 correspond to and communicate with the rainwater pipe 2, the third through hole 403 corresponds to and communicate with the sewage pipe 3, and the first through hole 401 is closed. At this time, rainwater can be discharged through the rainwater pipe 2 and the sewage pipe 3.
