Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage, and more specifically, to a municipal rainwater and sewage diversion pipe. Background Art
[0002] During the rainy season, in order to reduce the pressure of water accumulation in the environment, rainwater is generally discharged into rivers. In order to prevent rainwater from mixing with foreign objects on the ground and becoming sewage and flowing into rivers, most of the time, rainwater is diverted through rainwater and sewage diversion pipes to discharge clean rainwater into rivers.
[0003] In common rainwater and sewage diversion pipes, rainwater is filtered and diverted through filtering mechanisms, but common diversion structures can only divert garbage, mud, and other debris washed in by rainwater. After rainwater comes into contact with the ground, it may be mixed with some pollutants. These pollutants are dissolved in water and cannot be directly filtered, so that the rainwater discharged into the river is not completely clean. A large amount of discharge may also cause river pollution. In addition, because the rainwater flowing into the diversion structure will contain a large amount of debris washed from the ground, a large amount of debris will accumulate in the structure after long-term use, and regular cleaning is required. During this period, the ground needs to be excavated and the pipeline needs to be disassembled. The construction operation is large and inconvenient for workers to operate. In addition, the rainwater discharge pressure during the flood season is relatively high, and a large amount of garbage and other debris enters the pipeline. Common preliminary filtration is mostly a single-structure filter. Under a large amount of work, debris accumulates at the filter outlet, which may affect the flow of rainwater out of the filter and cause pipeline blockage. Utility Model Content

[0034] In this embodiment, the well body 1 is set underground and enters through the water inlet pipe 2. The rainwater chamber 4 provides a processing space. After the rainwater with debris and pollutants flows into the rainwater chamber 4, it first passes through the filter screen 6 frame 5, and is filtered and intercepted by the filter screen 6 in the filter screen 6 frame 5 to intercept the garbage, mud and other debris washed in by the rainwater.

[0043] Specifically, when installing the upper cover frame 20, the sealing block 23 is inserted into the first sealing groove 24, and the insertion frame 21 cooperates with the sealing block 23 through the second sealing groove 25. After the upper cover frame 20 is tightly closed and fixed, the sealing block 23 is located in the first sealing groove 24 and the second sealing groove 25, providing a sealing structure to avoid leakage and ensure the stability of rainwater filtration.
[0044] Please refer to Figure 3 As a further implementation of the limiting mechanism: the outer ends of the filter frame 5 and the purification frame 7 are both provided with limiting sliders 26, the inner sides of the rainwater chamber 4 and the extension frame 11 are both provided with limiting slide grooves 27, and the limiting sliders 26 and the limiting slide grooves 27 are slidably matched.
[0045] Specifically, when the filter frame 5 and the purification frame 7 move, the limit slider 26 will be driven to move.

[0049] Specifically, when the drive motor 13 drives the winding shaft 14 to rotate, the winding shafts 14 in the same group cooperate with each other through the transmission wheel 30 and the transmission belt 31. Through the transmission effect of the transmission belt 31, the two groups of transmission wheels 30 rotate synchronously, thereby ensuring that the rotation speed of the winding shaft 14 is consistent and the winding or releasing speed of the cable 15 is consistent.
[0050] In summary, when the overall equipment is in use (or running):
[0051] When the device is used for drainage, the well body 1 is set underground, rainwater enters through the water inlet pipe 2, and a processing space is provided through the rainwater chamber 4. After the rainwater with debris and pollutants flows into the rainwater chamber 4, it first passes through the filter screen 6 frame 5, and is filtered and intercepted by the filter screen 6 in the filter screen 6 frame 5. The first filter screen 16, the second filter screen 17 and the third filter screen 18 cooperate to filter the debris entering the rainwater chamber 4 in turn. The mesh diameters of the first filter screen 16, the second filter screen 17 and the third filter screen 18 are reduced in turn, and the three-layer filter screen mechanism filters the debris of different sizes in turn, and the debris with The garbage, mud and other debris washed in by the rainwater are intercepted, and the smaller debris will pass through the filter structure with a relatively large mesh diameter, so that the debris of different sizes will be accumulated in the filter frame 5 in batches. After passing through the filter frame 5, the rainwater containing pollutants will not be directly discharged into the river, but will pass through the purification frame 7, and then pass through the mineral filter layer 8, the fine sand filter layer 9 and the bamboo charcoal filter layer 10 in turn. Through the action of the mineral filter layer 8, the fine sand filter layer 9 and the bamboo charcoal filter layer 10, the pollutants in the rainwater are adsorbed and filtered. After treatment, the clean rainwater flows out from the outlet pipe 3 and is discharged into the river.
[0052] After the equipment has been working for a period of time, there will be certain debris inside. In the period when there is no rain, the sealing cover 12 is opened when the drainage structure is not working, exposing the inside of the extension frame 11. The extension frame 11 is connected to the rainwater chamber 4. There is no need to dig the ground to disassemble the drainage structure. By controlling the driving motor 13 to work, the driving motor 13 drives the winding shaft 14 to rotate, and the winding shaft 14 reels the cable 15. When the driving motor 13 drives the winding shaft 14 to rotate, the winding shaft 14 of the same group cooperates through the transmission wheel 30 and the transmission belt 31. Through the transmission belt 31 The transmission effect makes the two sets of transmission wheels 30 rotate synchronously, thereby ensuring the same rotation speed of the reel 14, and then ensuring the same reeling or releasing speed of the cable 15. The filter frame 5 and the purification frame 7 are lifted by the cable 15, and the garbage in the filter frame 5 and the purification layers in the purification frame 7 are cleaned or replaced. When cleaning the filter frame 5, the upper cover frame 20 is disassembled, and the inside of the main frame 19 can be cleaned to remove the debris everywhere. In addition, when the filter mechanism needs to be cleaned or replaced, the insertion frame 21 is punched into the insertion slot 22 and taken out. The corresponding first filter screen 16, the second filter screen 17 or the third filter screen 18 can be removed. When reinstalling, the insertion frame 21 with the corresponding filter screen is inserted into the insertion groove 22, and the insertion frame 21 is fixed through the insertion groove 22, so that the first filter screen 16, the second filter screen 17 and the third filter screen 18 cooperate with the filter screen frame 5 to ensure the stability of the corresponding filter screen structure. When installing the upper cover frame 20, the sealing block 23 is inserted into the first sealing groove 24, and the insertion frame 21 cooperates with the sealing block 23 through the second sealing groove 25. After the upper cover frame 20 is closed and fixed, the sealing block 23 is located A sealing structure is provided in the first sealing groove 24 and the second sealing groove 25 to avoid leakage and ensure the stability of rainwater filtration. Then the working drive motor 13 works to rotate the collecting shaft, unroll the cable 15, and lower the filter frame 5 and the purification frame 7. When the filter frame 5 and the purification frame 7 move, the limit slider 26 will be driven to move. Through the cooperation of the limit slider 26 and the limit slide groove 27, the filter frame 5 and the purification frame 7 remain stable during movement and stably cooperate with the rainwater chamber 4. Finally, the sealing cover plate 12 is closed and fixed, and the equipment is put into use again.
