Description

Technical Field

[0001] The utility model relates to the technical field of drainage engineering, in particular to a rainwater diversion and drainage mechanism. Background Art

[0002] Urban drainage systems typically separate rainwater and sewage, treating domestic sewage and rainwater separately to ensure effective sewage treatment, while rainwater is directly discharged or stored. However, in practice, sewage channels often face the problem of sedimentation during the process of transporting sewage. Because sewage contains large amounts of solid particles and organic matter, these substances easily accumulate in sewage channels, forming sediments, leading to poor drainage and even pipe blockage, thus affecting the normal operation of the entire drainage system.

[0003] Because the rainwater drainage system and sewage drainage system operate independently, rainwater cannot be diverted to the sewage system for flushing. Sedimentation in the sewage pipes lacks a natural flushing mechanism, requiring regular manual or mechanical cleaning. This not only increases maintenance costs and manpower, but also poses the risk of sewage pipes becoming clogged or unmaintained.

[0004] To this end, we propose a rainwater diversion and drainage mechanism. Utility Model Content

[0005] The utility model mainly solves the above technical problems and provides a rainwater diversion and drainage mechanism.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a rainwater diversion and drainage mechanism, which includes a rainwater channel and a sewage channel, wherein the rainwater channel is connected to an inlet pipe for guiding the inflow of external rainwater;

[0007] A flushing water regulating mechanism for flushing dirt in the sewage channel is provided between the rainwater channel and the sewage channel;

[0008] The flushing water regulating mechanism includes a water tank with a hollow interior, a connecting elbow connected to the interior of the rainwater channel is fixedly installed above the water tank, a partition is provided inside the water tank, the partition divides the interior of the water tank into two left and right cavities, a buoyancy block and a lifting block are respectively provided in the two cavities inside the water tank, a vertical groove is opened through the partition, a connecting plate is slidably installed in the vertical groove of the partition, and the two ends of the connecting plate are respectively fixedly connected to the buoyancy block and the lifting block;

[0009] The side wall surface of the rainwater channel is provided with a rainwater inflow port connected to the interior thereof, and the side wall surface of the sewage channel is provided with a rainwater inflow port connected to the interior thereof;

[0010] The buoyancy block can drive the lifting block through the connecting plate to simultaneously block or connect the rainwater inflow outlet and the rainwater inflow inlet.

[0011] Preferably, a built-in block is fixedly installed inside the lifting block, and a guide groove with a C-shaped cross section is formed between the outer wall surface of the built-in block and the inner wall surface of the lifting block.

[0012] Preferably, the lifting block is provided with a sealing surface on one side close to the rainwater channel and the sewage channel. When there is no rainwater in the water tank, the buoyancy block has no buoyancy effect, and the sealing surface of the lifting block is fitted and distributed at the positions corresponding to the rainwater outlet and the rainwater inlet and plays a sealing role; when rainwater flows into the water tank through the connecting elbow, the buoyancy block is gradually affected by the buoyancy and drives the lifting block to move, and the guide groove of the lifting block connects the rainwater outlet and the rainwater inlet.

[0013] Preferably, a drainage elbow is fixedly installed on the bottom surface of the water tank, and one end of the drainage elbow away from the water tank extends to the inside of the sewage channel.

[0014] Preferably, a one-way valve is provided inside the drainage elbow.

[0015] Beneficial effects

[0016] The utility model provides a rainwater diversion and drainage mechanism. It has the following beneficial effects:

[0017] (1) This rainwater diversion and drainage mechanism has the following characteristics: in the initial state, there is no rainwater in the water tank. At this time, the buoyancy block has no buoyancy effect. The buoyancy block is distributed in the initial position with the lifting block. At this time, the blocking surface is distributed at the position corresponding to the rainwater outlet and the rainwater inlet. The rainwater outlet and the rainwater inlet are blocked by the connecting plate. When rainwater enters the water tank, as the water level in the water tank rises, the buoyancy block slowly floats up. The buoyancy block moves up with the lifting block through the connecting plate. During the upward movement, the blocking surface of the lifting block is misaligned with the rainwater outlet and the rainwater inlet. The greater the upward movement of the lifting block, the larger the opening area of ​​the rainwater outlet and the rainwater inlet. At this time, the rainwater in the rainwater channel will be diverted into the sewage channel through the rainwater outlet, the diversion trough and the rainwater inlet in turn. Through the drainage and flushing of rainwater, the sedimentation of dirt inside the sewage channel can be effectively prevented, avoiding the problem of poor drainage or blockage caused by excessive sediment.

[0018] (2) In this rainwater diversion and drainage mechanism, the higher the water level in the water tank, the greater the upward sliding amplitude of the lifting block, and the larger the opening area of ​​the rainwater outlet, thereby facilitating the flow control of rainwater entering the sewage channel. When the buoyancy block rises to the highest point in the water tank, the opening areas of the rainwater outlet and the rainwater inlet are maximized. In the case of heavy rain or heavy rainfall, the device can automatically guide a large flow of rainwater to flush the sediment in the sewage channel, effectively improving the drainage capacity and cleaning effect of the channel, and ensuring that the sewage channel always remains unobstructed.

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Embodiment: A rainwater diversion and drainage mechanism, such as Figures 1-6 As shown, it includes a rainwater channel 1 and a sewage channel 2. The rainwater channel 1 is connected to an inlet pipe 3 for guiding external rainwater to flow in. Rainwater is introduced into the rainwater channel 1 through the inlet pipe 3 and discharged outward through the rainwater channel 1. Domestic sewage is discharged outward through the sewage channel 2. The sewage channel 2 is prone to dirt precipitation during the sewage transportation process. A flushing water regulating mechanism 4 is provided between the rainwater channel 1 and the sewage channel 2 for flushing dirt in the sewage channel 2.

[0031] Furthermore, the flushing water regulating mechanism 4 includes an internal hollow water tank 400, a connecting elbow 401 connected to the inside of the rainwater channel 1 is fixedly installed above the water tank 400, a partition 402 is provided inside the water tank 400, and the partition 402 divides the inside of the water tank 400 into two cavities on the left and right, and a buoyancy block 404 and a lifting block 406 are respectively provided in the two cavities inside the water tank 400, a vertical groove is opened through the partition 402, and a connecting plate 403 is slidably installed in the vertical groove of the partition 402, and the two ends of the connecting plate 403 are fixedly connected to the buoyancy block 404 and the lifting block 406 respectively, and a drainage elbow 407 is fixedly installed on the bottom surface of the water tank 400, and the drainage elbow 407 is away from the water. One end of the box 400 extends to the interior of the sewage channel 2. When the rainwater flow in the rainwater channel 1 is small, the rainwater in the rainwater channel 1 will not be diverted into the water tank 400 through the connecting elbow 401. On the contrary, when the rainwater flow in the rainwater channel 1 is large and the water level exceeds the position of the connecting elbow 401, a portion of the rainwater in the rainwater channel 1 will be diverted into the water tank 400 through the connecting elbow 401. When the amount of rainwater entering the water tank 400 is greater than the amount discharged from the drainage elbow 407, the water level in the water tank 400 will rise higher and higher, causing the buoyancy block 404 to rise and fall with the change of the water level in the water tank 400. The buoyancy block 404 will rise and fall synchronously with the lifting block 406 through the connecting plate 403.

[0032] Furthermore, a rainwater inflow port 10 communicating with the interior of the rainwater channel 1 is provided on the side wall surface, and a rainwater inflow port 20 communicating with the interior of the sewage channel 2 is provided on the side wall surface;

[0033] The buoyancy block 404 can drive the lifting block 406 through the connecting plate 403 to simultaneously block or connect the rainwater inflow outlet 10 and the rainwater inflow inlet 20.

[0034] Among them, the lifting block 406 is fitted and distributed at the positions corresponding to the rainwater outlet 10 and the rainwater inlet 20, and a built-in block 416 is fixedly installed inside the lifting block 406. A guide groove 426 with a C-shaped cross-section is formed between the outer wall of the built-in block 416 and the inner wall of the lifting block 406. The lifting block 406 is provided with a sealing surface 436 on one side close to the rainwater channel 1 and the sewage channel 2. When there is no rainwater in the water tank 400, the buoyancy block 404 has no buoyancy effect, and the sealing surface 436 of the lifting block 406 is fitted and distributed at the positions corresponding to the rainwater outlet 10 and the rainwater inlet 20 and plays a sealing role; when rainwater flows into the water tank 400 through the connecting elbow 401, the buoyancy block 404 is gradually affected by the buoyancy and drives the lifting block 406 to move, and the guide groove 426 of the lifting block 406 connects the rainwater outlet 10 and the rainwater inlet 20. During the upward movement of the lifting block 406, the blocking surface 436 is misaligned with the rainwater outlet 10 and the rainwater inlet 20. The greater the upward movement of the lifting block 406, the larger the opening area of ​​the rainwater outlet 10 and the rainwater inlet 20. At this time, the rainwater in the rainwater channel 1 will be diverted into the sewage channel 2 through the rainwater outlet 10, the guide groove 426 and the rainwater inlet 20 in turn, thereby flushing the sediment in the sewage channel 2. When the buoyancy block 404 rises to the highest point in the water tank 400, the opening areas of the rainwater outlet 10 and the rainwater inlet 20 are maximized, and more rainwater flows into the sewage channel 2, thereby improving the flushing efficiency in the sewage channel 2.

[0035] Preferably, the rainwater channel 1 and the sewage channel 2 are prefabricated structures formed in one piece.

[0036] Furthermore, the rainwater channel 1 is located above the sewage channel 2 .

[0037] The working principle of this utility model:

[0038] In the initial state, there is no rainwater in the water tank 400. At this time, the buoyancy block 404 has no buoyancy effect. The buoyancy block 404 is distributed in the initial position with the lifting block 406. At this time, the blocking surface 436 is fitted and distributed at the positions corresponding to the rainwater outlet 10 and the rainwater inlet 20. The rainwater outlet 10 and the rainwater inlet 20 are blocked by the connecting plate 403. When rainwater enters the water tank 400, as the water level in the water tank 400 rises, the buoyancy block 404 slowly floats up, and the buoyancy block 404 moves upward with the lifting block 406 through the connecting plate 403. The sealing surface 436 is formed during the upward movement. 436 is misaligned with the rainwater outlet 10 and the rainwater inlet 20. The greater the upward movement of the lifting block 406, the larger the opening area of ​​the rainwater outlet 10 and the rainwater inlet 20. At this time, the rainwater in the rainwater channel 1 will be diverted into the sewage channel 2 through the rainwater outlet 10, the guide groove 426 and the rainwater inlet 20 in sequence, thereby flushing the sediment in the sewage channel 2. When the buoyancy block 404 rises to the highest point in the water tank 400, the opening areas of the rainwater outlet 10 and the rainwater inlet 20 are maximized, and more rainwater flows into the sewage channel 2, thereby improving the flushing efficiency in the sewage channel 2.
