A blocking device is fixedly connected to the inner wall of the pool body on the side away from the control pipe and close to the outlet pipe. Rotating grooves are opened at both ends of the side wall of the pool body in the length direction of the blocking device. A retrieval device for retrieving garbage from the blocking device is rotatably connected to the inner wall of the rotating groove. A collection box for collecting garbage from the retrieval device is fixedly connected to both ends of the outer wall of the pool body in the length direction of the blocking device.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A rainwater and sewage separation device, such as Figure 1 and Figure 3 As shown, the system includes a pool body 1, on which an inlet pipe 2, a sewage interceptor pipe 3, and an outlet pipe 4 are installed. The inlet pipe 2 and the outlet pipe 4 are connected by a control pipe 5. The outlet pipe 4, the control pipe 5, and the sewage interceptor pipe 3 are all equipped with an air inflation device 7 controlled by a controller 6. When the weather is sunny, the air inflation device 7 in the control pipe 5 blocks the control pipe 5, and the air inflation device 7 in the sewage interceptor pipe 3 deflates, allowing the sewage in the inlet pipe 2 to be discharged into the sewage treatment plant through the sewage interceptor pipe 3. When the rainfall is light, the air inflation devices 7 in the control pipe 5 and the sewage interceptor pipe 3 are both in a deflated state, and the air inflation device 7 in the outlet pipe 4 blocks the outlet pipe 4, allowing the initial flow of water during the rainfall to still flow into the sewage treatment plant. When the rainfall is heavy, the air inflation devices 7 in the outlet pipe 4 and the control pipe 5 are in a deflated state, and the air inflation device 7 in the sewage interceptor pipe 3 blocks the sewage interceptor pipe 3, at which time the water flows into the natural water body.

[0020] like Figures 1-4 As shown, a blocking device is cast on the inner wall of the pool body 1 on the side away from the control pipe 5 and close to the outlet pipe 4. The blocking device can block garbage floating above the water flow. Rotating grooves 8 are opened at both ends of the side wall of the pool body 1 along the length of the blocking device. A retrieval device for retrieving garbage from the blocking device is rotatably connected to the inner wall of the rotating groove 8. A collection box 9 for collecting garbage from the retrieval device is fixedly connected to both ends of the outer wall of the pool body 1 along the length of the blocking device. The retrieval device can retrieve garbage attached to the inner wall of the blocking device during rotation. When the retrieval device passes the collection box 9 during rotation, the garbage on the retrieval device enters the collection box 9 together with the retrieval device under the action of inertia.

[0021] like Figure 2As shown, the retrieval device includes a rotating shaft 10 and two retrieval rods 11. The two retrieval rods 11 are symmetrically arranged along the rotating shaft 10. The rotating shaft 10 is rotatably connected to its inner wall, and the retrieval rods are slidably connected to the inner wall of the blocking device. When the rotating shaft 10 rotates, it drives the rotating rods to rotate. As the rotating rods in the blocking device rotate upwards, they scrape off the debris attached to the inner wall of the blocking device and carry the debris into the collection box 9 for collection. When the length of the retrieval rod 11 is half the length of the blocking device, the retrieval rods 11 at both ends of the blocking device can clean most of the area of ​​the blocking device. The cross-sectional shape of the end of the retrieval rod 11 away from the rotating shaft 10 is arc-shaped to avoid mutual interference between the two retrieval rods 11 located in the blocking device during rotation. The retrieval rods 11 face the direction of rotation. A scooping groove 12 is formed by an inward indentation on one side. The scooping groove 12 allows the garbage in the blocking device to be better pulled into the collection box 9. Several water outlet holes 13 are opened on the bottom surface of the scooping groove 12 to facilitate the flow of water out of the scooping groove 12, reducing the probability of water being carried into the collection box 9 by the scooping groove 12. A scraper 17 is rotatably connected to the side of the collection box 9 away from the pool body 1 and away from the ground. The width of the scraper 17 is the same as the width of the scooping groove 12. When the scooping rod 11 rotates into the collection box 9 and continues to rotate, the end of the scraper 17 near the pool body 1 will slide against the bottom surface of the scooping groove 12, scraping the garbage in the scooping groove 12 down into the collection box 9. The cross-sectional shape of the side of the scraper 17 away from the ground and near the pool body 1 is arc-shaped, which makes the resistance when the scooping rod 11 pushes the scraper 17 to rotate less.

[0022] like Figure 2 As shown, the blocking device includes a front baffle 14 and a rear baffle 15. The front baffle 14 and the rear baffle 15 are at the same distance from the ground on the side closest to the ground. When the retrieval rod 11 is located between the front baffle 14 and the rear baffle 15, the retrieval rod 11 can reduce the probability of garbage passing over the rear baffle 15 with the water flow through the space between the front baffle 14 and the rear baffle 15 to a certain extent. The height of the rear baffle 15 is greater than the height of the front baffle 14. The rear baffle 15 has several through holes 16 extending through its width. After the water flow carries the garbage over the front baffle 14, the garbage will be blocked by the rear baffle 15. The water flow can pass through the rear baffle 15 through the through holes 16 on the rear baffle 15.

[0023] like Figures 2-4As shown, the inner wall of the rotating groove 8 is provided with sealing parts 18 on both the upper and lower sides of the rotating shaft 10 for sealing the rotating groove 8. The sealing parts 18 are made of flexible material. When the retrieval rod 11 does not pass through the rotating groove 8, the two sealing parts 18 on the inner wall of the rotating groove 8 located on one side of the rotating shaft 10 abut against each other to seal the rotating groove 8, so that the storage box 9 is not connected to the pool body 1 at this time, reducing the probability of water flowing from the pool body 1 into the storage box 9. When the retrieval rod 11 passes through the rotating groove 8, it will squeeze the sealing parts 18 to allow the retrieval rod 11 to enter the storage box 9 from the rotating groove 8.

[0024] like Figure 1 , Figure 3 , Figure 4 As shown, a receiving groove 19 is provided on the side wall of the rotating groove 8 near the control tube 5. The receiving groove 19 coincides with the central axis of the rotating shaft 10 in the height direction, and the cross-sectional area of ​​the receiving groove 19 is smaller than that of the rotating shaft 10. A motor 20 is riveted to the inner wall of the receiving groove 19. The drive end of the motor 20 is rotatably connected to the rotating shaft 10. The motor 20 is electrically connected to the controller 6. When the motor 20 receives a signal from the controller 6, the motor 20 will drive the rotating shaft 10 and the retrieval rod 11 to rotate 180° once. It rotates once every half hour. The receiving groove 19 plays the role of storing the motor 20, and the receiving groove 19 can be completely blocked by the rotating shaft 10 to prevent water in the pool 1 from flowing into the receiving groove 19 and causing leakage.

[0025] Working principle: A rainwater and sewage separation device. When the rainfall is heavy, the air inflator 7 of the outlet pipe 4 and control pipe 5 is in a deflated state. At this time, as the water flows from the control pipe 5 to the outlet pipe 4, the garbage floating above the water flow is blocked on the rear baffle 15 when the water flows past the front baffle 14 and the rear baffle 15, and cannot enter the outlet pipe 4 with the water flow. The controller 6 sends a signal to the motor 20 in the receiving tank 19, so that the motor 20 drives the rotating shaft 10 every half hour. The scooping rod 11 rotates 180°. During the rotation, the scooping rod 11 scrapes the garbage off the rear baffle 15. The scooping trough 12 can temporarily store the garbage scraped off the rear baffle 15 and squeeze the sealing part 18 into the collection box 9, bringing the garbage into the collection box 9 for storage. When the scraper 17 in the collection box 9 is subjected to the pressure of the rotating rod, it will abut against the inner bottom surface of the rotating trough 8 and deform. The scraper 17 can scrape the garbage temporarily stored in the scooping trough 12 and collect it in the collection trough.

All technical solutions falling within the scope of this utility model's concept are protected.
