Description

Technical Field

[0001] This invention belongs to the field of sewer technology, and more specifically, relates to a drainage device for building engineering. Background Technology

[0002] During the construction process, temporary drainage pipes are often laid at construction sites to collect and remove the wastewater generated. Temporary drainage pipes used at construction sites are prone to clogging due to various building materials and silt. There are several reasons for this. For example, construction generates a large amount of building debris, such as broken bricks, ceramic tile fragments, and insulation material fragments. This debris can easily enter the temporary drainage pipes through manholes or unsealed drain outlets, especially during wall demolition and ground excavation. Without effective protection, these fragments can fall directly into the pipes, causing blockages. Furthermore, construction site drainage also includes large amounts of wastewater containing silt, such as groundwater drainage during foundation construction and concrete curing drainage. This silt accumulates in the pipes with the water flow, and a large amount of sand enters the drainage pipes with the water. Effectively and promptly cleaning the accumulated building materials and silt from the drainage pipes has always been a significant problem in construction engineering. Frequent blockages in construction site drainage pipes not only affect construction speed, quality, and safety, but also require significant manpower, resources, and time for frequent unclogging. Therefore, it is very important to do a good job of daily maintenance of drainage pipes on construction sites. Good maintenance can effectively reduce the number of times temporary drainage pipes are blocked. Summary of the Invention

[0028] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0029] A building construction drainage device includes a front drainage pipe 1, a rear drainage pipe 37, and a sludge removal device for the front drainage pipe 1. The outlet end of the front drainage pipe 1 is inserted into the sedimentation tank 2 of the sludge removal device, and the inlet end of the rear drainage pipe 37 is inserted into the sedimentation tank 2 of the sludge removal device. The sludge removal device is used to remove construction waste, silt, etc., from the front drainage pipe 1, thereby effectively preventing the accumulation of silt, stones, etc., in the front drainage pipe 1 and avoiding serious blockage problems. It also effectively prevents silt, stones, etc., from flowing into the rear drainage pipe 37. In this invention, both the front drainage pipe 1 and the rear drainage pipe 37 refer to drainage pipes in a construction site. The front drainage pipe 1 discharges sewage to the sedimentation tank 2, and the rear drainage pipe 37 discharges sewage out of the sedimentation tank 2. In a construction site, the installation location and number of sludge removal devices can be rationally designed according to the distribution of drainage pipes. In this invention, the front drainage pipe 1, the rear drainage pipe 37, and the dredging device are all buried underground. The depth of the front drainage pipe 1 and the rear drainage pipe 37 underground can be set to 1-2 meters. Both the front drainage pipe 1 and the rear drainage pipe 37 are made of cast iron pipe.

[0030] The dredging device includes a sedimentation tank 2 and a sludge-pushing mechanism installed inside the front drain pipe 1. In this invention, the sedimentation tank 2 is used to collect silt, sand, stones, etc. flowing out of the front drain pipe 1 to prevent these silt, sand, stones, etc. from flowing into the rear drain pipe 37. The sedimentation tank 2 is made of metal, specifically stainless steel. The sedimentation tank 2 needs to be buried underground during use, with a height greater than the burial depth of the front drain pipe 1. During use, the sewage in the front drain pipe 1 first flows into the sedimentation tank 2. Due to the weight of the silt, sand, stones, etc., they will sink to the bottom of the sedimentation tank 2. The sludge-pushing mechanism is used to frequently clean the front drain pipe 1 to ensure its cleanliness and prevent blockage and sludge accumulation. During construction at the construction site, the sludge-pushing mechanism can be activated multiple times a day to clean the front drain pipe 1. Multiple front drain pipes 1 can be connected to the sedimentation tank 2 simultaneously, and the sewage discharged from multiple front drain pipes 1 flows into the rear drain pipe 37 through the sedimentation tank 2.

[0031] The outlet end of the front drain pipe 1 is inserted into the sedimentation tank 2. The sludge pushing mechanism includes a slide rail 3 installed on the top of the inner wall of the front drain pipe 1. A slider 4 is slidably installed on the slide rail 3. The invention installs the slide rail 3 on the top of the inner wall of the front drain pipe 1, which facilitates the slider 4 to slide along the slide rail 3 in the front drain pipe 1, thereby driving the push plate 6 to reciprocate in the front drain pipe 1. The top surface of the slide rail 3 has multiple slide rail threaded holes spaced apart, and the top surface of the slide rail 3 is an arc-shaped surface that matches the inner wall of the front drain pipe 1. The top of the front drain pipe 1 has multiple fixing holes 50 spaced apart, which match the slide rail threaded holes. Fixing nuts 51 are installed between the fixing holes 50 and the slide rail threaded holes. To facilitate the fixing of the fixing nuts 51, a boss can be welded on each fixing hole 50 of the front drain pipe 1. The boss has a through hole that connects to the fixing hole 50. The top surface of the boss is flat, which facilitates the tightening of the fixing nuts 51 onto the front drain pipe 1. The front drain pipe 1 is generally used by connecting multiple drain pipes to form a long drain pipe. However, when the drainage distance is short, only one drain pipe can be used. When installing the slide rail 3, it needs to be pre-installed in the single drain pipe. During installation, a fixing hole 50 can be drilled on the drain pipe, and a boss can be installed on the fixing hole 50. Then, the slide rail threaded hole on the top surface of the slide rail 3 is aligned with the fixing hole 50. The outer diameter of the fixing hole 50 is larger than the inner diameter of the slide rail threaded hole. After alignment, the fixing bolts are screwed in sequentially. The slide rail 3 is inserted into the fixing hole 50 and the fixing threaded hole; arc-shaped plates 52 are fixedly installed at both ends of the slide rail 3 respectively. The arc-shaped plates 52 are semi-circular rings. The slide rail 3 is in the middle of the arc-shaped plates 52. The arc-shaped plates 52 are fixed to the inner wall of the front drain pipe 1 by welding. In this invention, the slide rail 3 and the arc-shaped plates 52 are fixedly connected by welding, and the arc-shaped plates 52 are fixedly connected to the inner wall of the front drain pipe 1 by welding. The arc-shaped plates 52 can make the slide rail 3 more firmly fixed in the front drain pipe 1 and facilitate the positioning of the guide rail.

[0032] The slider 4 is driven to slide along the slide rail 3 by a drive assembly, which includes a drive motor 40 installed in the sedimentation tank 2 and a drive chain 41 installed in the front drain pipe 1. An upper opening 42 is opened at the top of the water inlet end of the front drain pipe 1, and a first sprocket 43 is rotatably installed inside the upper opening 42. The drive chain 41 passes through the upper opening 42 and is fitted onto the first sprocket 43 on the upper opening 42. A second sprocket 44 is rotatably installed at the water outlet end of the front drain pipe 1 inside the sedimentation tank 2. The first sprocket 43 and the second sprocket 44 are respectively located at the water inlet and water outlet ends of the front drain pipe 1, and both ends of the drive chain 41 are respectively fitted onto the first sprocket 43 and the second sprocket 44. A tension sprocket may also be installed on the drive chain 41.

[0033] The two ends of the drive chain 41 are fixedly connected to the left and right ends of the slider 4, respectively. The drive chain 41 and the slider 4 form a closed ring structure. The outer wall of the front drain pipe 1 is fitted with a chain protective shell 45 on the outside of the drive chain 41. The drive motor 40 is driven by the second sprocket 44. A support plate 46 is installed on the inner wall of the sedimentation tank 2. The drive motor 40 is fixedly installed on the support plate 46 by bolts. Two vertical plates 47 are fixedly installed on the lower side of the support plate 46. A sprocket shaft 48 is rotatably installed between the two vertical plates 47. The second sprocket 44 is fixedly installed on one side of the sprocket shaft 48. A lower drive sprocket is fixedly installed on one side of the second sprocket 44. The output shaft of the drive motor 40 is connected to the upper drive sprocket. The upper drive sprocket and the lower drive sprocket are connected by a chain. In operation, the drive motor 40 drives the lower transmission sprocket to rotate via a chain. Since both the lower transmission sprocket and the second sprocket 44 are fixedly connected to the sprocket shaft 48, the second sprocket 44 rotates synchronously. The second sprocket 44 drives the drive chain 41 to rotate forward or backward, thereby driving the slider 4 to move reciprocally along the slide rail 3. The drive motor 40 of this invention is equipped with an overload protection device. The chain protective shell 45 is fixed to the front drain pipe 1 by welding. The chain protective shell 45 can seal and protect the drive chain 41 and isolate the front drain pipe 1 from the outside. The inner wall of the front drain pipe 1 has a protective plate 49 on the side of the upper opening 42 near the water inlet end of the front drain pipe 1. By setting the protective plate 49, this invention can effectively protect the chain. The first baffle 30 and the second baffle 31 are respectively provided with through holes for the drive chain 41 to pass through.

[0034] A support rod 5 is rotatably mounted on the bottom of the slider 4, and a push plate 6 is mounted on the bottom of the support rod 5. The bottom of the push plate 6 is arc-shaped, and multiple insert rods 38 are spaced apart on the working surface of the push plate 6. Each insert rod 38 has a pointed tip. A rubber strip 39 is mounted on the bottom of the push plate 6. During the reciprocating movement of the slider 4, it simultaneously drives the support rod 5 and the push plate 6 to reciprocate. Because the bottom of the push plate 6 is arc-shaped and matches the inner wall of the front drain pipe 1, and the push plate 6... The distance between the bottom surface of the push plate 6 and the bottom of the inner wall of the front drain pipe 1 is very small. If the bottom of the push plate 6 is fitted with a rubber strip 39, and the push plate 6 and the rubber strip 39 are a whole, then the distance between the bottom surface of the rubber strip 39 and the bottom of the inner wall of the front drain pipe 1 is very small. Therefore, when the support rod 5 is vertical and the push plate 6 moves from the inlet end to the outlet end of the front drain pipe 1, the push plate 6 will push the mud, sand, bricks and other debris accumulated in the front drain pipe 1 into the sedimentation tank 2, thereby cleaning the front drain pipe 1.

[0035] A rotating structure is installed between the support rod 5 and the slider 4. The rotating structure of the present invention can achieve the following: when the support rod 5 moves from the inlet end to the outlet end along the front drain pipe 1, the support rod 5 is vertical. At this time, the push plate 6 at the bottom of the support rod 5 can clean the front drain pipe 1. When the support rod 5 moves from the outlet end to the inlet end along the front drain pipe 1, the support rod 5 is horizontal. At this time, the height difference between the push plate 6 at the bottom of the support rod 5 and the bottom of the inner wall of the front drain pipe 1 is relatively large. By setting the rotating structure, the present invention can effectively achieve the push plate 6 to clean the front drain pipe 1 repeatedly.

[0036] The rotating structure includes a housing 7 fixedly installed at the bottom of the slider 4. A rotating shaft 8 is rotatably installed inside the housing 7, and the rotating shaft 8 can rotate relative to the housing 7. A fixed shaft 9 is fixedly installed on the upper side of the rotating shaft 8 inside the housing 7. A first ratchet 10 and a second ratchet 11 with opposite rotation directions are fixedly installed on both sides of the rotating shaft 8. A gear 19 is also fixedly installed on the rotating shaft 8, between the first ratchet 10 and the second ratchet 11. One end of the support rod 5 is fixedly installed on the rotating shaft 8 and between the first ratchet 10 and the second ratchet 11. The rotation of the gear 19 can simultaneously drive the rotating shaft 8, the first ratchet 10, the second ratchet 11, and the support rod 5 to rotate. The housing 7 has a rotating groove 12 for the support rod 5 to rotate on the side near the water inlet end of the front drain pipe 1. The rotating groove 12 is L-shaped. By reasonably designing the length of the rotating groove 12, the rotation angle of the support rod 5 in the rotating groove 12 can be 90 degrees.

[0037] On both sides of the fixed shaft 9, a first pawl 13 that engages with the first ratchet 10 and a second pawl 14 that engages with the second ratchet 11 are rotatably mounted. A first spring 34 is installed between the first pawl 13 and the side wall of the housing 7, and a second spring 35 is installed between the second pawl 14 and the side wall of the housing 7. The first spring 34 can drive the first pawl 13 to contact the first ratchet 10, and the second spring 35 can drive the second pawl 14 to contact the second ratchet 11. By setting the first spring 34 and the second spring 35, the present invention can make the first pawl 13 and the second pawl 14 have better resilience.

[0038] The first pawl 13 is fitted onto the fixed shaft 9 via a first sleeve 15. A first lever 16 is mounted on the bottom of the first sleeve 15. By rotating the first lever 16, the first sleeve 15 and the first pawl 13 can be rotated. The second pawl 14 is fitted onto the fixed shaft 9 via a second sleeve 17. A second lever 18 is mounted on the bottom of the second sleeve 17. By rotating the second lever 18, the second sleeve 17 and the second pawl 14 can be rotated.

[0039] The housing 7 is slidably mounted with a first actuating plate 20 and a second actuating plate 21 on the lower side of the first sleeve 15 and the second sleeve 17, respectively. The two ends of the first actuating plate 20 and the two ends of the second actuating plate 21 pass through the housing 7, and through holes are opened on both sides of the housing 7 for the first actuating plate 20 and the second actuating plate 21 to pass through.

[0040] The first actuating plate 20 is provided with a first step 22 that cooperates with the first lever 16. The top of the first actuating plate 20 is provided with a first bottom surface 23 on the side of the first step 22 near the water inlet end of the front drain pipe 1, and the top of the first actuating plate 20 is provided with a first top surface 24 on the side of the first step 22 near the water outlet end of the front drain pipe 1. The height of the first top surface 24 is higher than the first bottom surface 23. The height of the first step 22 increases along the direction from the water inlet end to the water outlet end of the front drain pipe 1. The second actuating plate 21 is provided with a second step 25 that cooperates with the second lever 18. The top of the second actuating plate 21 is provided with a second top surface 26 on the side of the second step 25 near the water inlet end of the front drain pipe 1, and the top of the second actuating plate 21 is provided with a second bottom surface 27 on the side of the second step 25 near the water outlet end of the front drain pipe 1. The height of the second top surface 26 is higher than the second bottom surface 27. The height of the second step 25 decreases along the direction from the water inlet end to the water outlet end of the front drain pipe 1. The first step 22 is on the side of the second step 25 near the water inlet end of the front drain pipe 1.

[0041] When the first step 22 contacts the first lever 16 and the first step 22 moves to the water inlet side of the front drain pipe 1, since the bottom of the first lever 16 is below the first top surface 24 at this time, the first step 22 will push the first lever 16 to rotate clockwise by a certain angle and make the bottom of the first lever 16 contact the first top surface 24. While the first lever 16 rotates, it will drive the first sleeve 15 and the first pawl 13 to rotate clockwise by a certain angle. At this time, the first pawl 13 will rotate to the upper side of the first ratchet 10, thereby realizing the separation of the first pawl 13 from the first ratchet 10.

[0042] When the bottom of the first lever 16 contacts the first top surface 24 and the bottom of the first lever 16 moves from the first top surface 24 to the upper side of the first bottom surface 23, the first pawl 13 will rotate counterclockwise under the action of gravity and spring until it contacts the first ratchet 10. At the same time, the first sleeve 15 and the first lever 16 also rotate counterclockwise.

[0043] Similarly, when the second step 25 contacts the second lever 18 and the second step 25 moves to the outlet side of the front drain pipe 1, since the bottom of the second lever 18 is below the second top surface 26 at this time, the second step 25 will push the second lever 18 to rotate counterclockwise by a certain angle, and make the bottom of the second lever 18 contact the second top surface 26. At the same time, the second lever 18 will drive the second sleeve 17 and the second pawl 14 to rotate counterclockwise by a certain angle. At this time, the second pawl 14 will rotate to the upper side of the second ratchet 11, thereby realizing the separation of the second pawl 14 and the second ratchet 11.

[0044] When the bottom of the second lever 18 contacts the second top surface 26 and the bottom of the second lever 18 moves from the second top surface 26 to the upper side of the second bottom surface 27, the second pawl 14 will rotate clockwise under the action of gravity and spring until it contacts the second ratchet 11, while the second sleeve 17 and the second lever 18 also rotate clockwise.

[0045] A drive plate 28 is slidably mounted on the housing 7 below the gear 19. Both ends of the drive plate 28 extend out of the housing 7. The housing 7 has through holes for the drive plate 28 to pass through. The top of the drive plate 28 is provided with a rack 29 that cooperates with the gear 19. The rack 29 on the drive plate 28 will drive the gear 19 to rotate. The rotation of the gear 19 will simultaneously drive the rotating shaft 8, the first ratchet 10, the second ratchet 11 and the support rod 5 to rotate. Preferably, two gears 19 are fixedly installed on the rotating shaft 8, and the two gears 19 are respectively on both sides of the support rod 5. A drive plate 28 is slidably installed on the lower side of each gear 19 in the housing 7. The two drive plates 28 are connected by a lower connecting plate 36 on the side near the water outlet end of the front drain pipe 1. The drive plate 28 has a protruding edge 57 at the end near the water inlet end of the front drain pipe 1. The size of the protruding edge 57 is larger than the through hole through which the drive plate 28 passes on the housing. By setting the protruding edge 57 and the lower connecting plate 36, the present invention can limit the stroke of the drive plate 28 and prevent the drive plate 28 from sliding out of the through hole on the housing 7 corresponding to the drive plate 28.

[0046] Both ends of the second actuating plate 21 and both ends of the first actuating plate 20 extend out of the housing 7. A first baffle 30 and a second baffle 31 are respectively installed at both ends of the slide rail 3. Both ends of the first actuating plate 20 are connected to the second actuating plate 21 via upper connecting plates 32. The lower sides of both upper connecting plates 32 are connected to upright plates 33. The driving plate 28 is located between the two upright plates 33, and the distance between the inner sides of the two upright plates 33 is greater than the length of the driving plate 28. This invention connects the first actuating plate 20 and the second actuating plate 21 using upper connecting plates 32, making the first actuating plate 20 and the second actuating plate 21 a single unit. By setting the two upright plates 33 and placing the driving plate 28 between the two upright plates 33, this invention allows the upright plates 33 to push the driving plate 28 when moving. The length of the driving plate 28 is less than the distance between the inner sides of the two upright plates 33. In use, the first baffle 30 and the second baffle 31 can respectively contact the upper sides of the two upright plates 33.

[0047] The first baffle 30 is installed near the water inlet end of the front drain pipe 1, and the second baffle 31 is installed near the water outlet end of the front drain pipe 1. By setting the first baffle 30, when the slider 4 drives the upright plate 33 near the water inlet end of the front drain pipe 1 to contact the first baffle 30, the first baffle 30, being fixed to the slide rail 3, will push the upright plate 33 to slide towards the water outlet end of the front drain pipe 1. Similarly, by setting the second baffle 31, when the slider 4 drives the upright plate 33 near the water outlet end of the front drain pipe 1 to contact the second baffle 31, the second baffle 31, being fixed to the slide rail 3, will push the upright plate 33 to slide towards the water inlet end of the front drain pipe 1.

[0048] The lower side of the outlet end of the front drain pipe 1 is provided with a notch 56. By providing a notch 56 on the lower side of the outlet end of the front drain pipe 1, when the support rod 5 slides to the outlet end of the front drain pipe 1 and is about to rotate under the action of the second baffle 31, the push plate 6 will be above the notch 56 on the lower side of the outlet end of the front drain pipe 1. This makes it convenient for the push plate 6 to push all the mud and sand in the front drain pipe 1 into the sedimentation tank 2.

[0049] The sedimentation tank 2 is also equipped with a cleaning assembly, which is used to remove the sediment from the sedimentation tank 2. The cleaning assembly includes a hopper elevator 53. The bottom of the sedimentation tank 2 is provided with an inclined plate 54. The hopper elevator 53 is located inside the sedimentation tank 2 and on one side of the lower end of the inclined plate 54. A discharge port is provided on one side of the top of the hopper elevator 53, and a garbage bin 55 is provided below the discharge port. In use, sediment such as mud and stones entering the sedimentation tank 2 will slide from the inclined plate 54 to the hopper elevator 53. By turning on the hopper elevator 53, the hopper elevator 53 will lift the sediment that has slid into the hopper elevator 53 to the highest point during rotation. At the highest point, the sediment will be transported to the garbage bin through the discharge port by centrifugal force. In use, the hopper elevator 53 can be turned on once a day for cleaning.

[0050] The working process of this invention:

[0051] This invention is used for the daily maintenance of drainage pipes at construction sites. It allows for multiple cleanings of the drainage pipes throughout the day, preventing blockages and silt buildup. Before cleaning, such as... Figure 3 , Figure 5 and Figure 6 As shown, the initial state of the support rod 5 is at the outlet end of the front drain pipe 1, and the support rod 5 is horizontal. At this time, the first actuating plate 20, the second actuating plate 21 and the driving plate 28 are pushed to the side closest to the inlet end of the front drain pipe 1 by the first baffle 30 through the upright plate 33. Moreover, since the distance between the inner sides of the two upright plates 33 is greater than the length of the driving plate 28, the inner side of the upright plate 33 near the inlet end of the front drain pipe 1 is a certain distance away from the driving plate 28. At this time, the first pawl 13 in the rotating structure is above the first ratchet 10 and does not contact the first ratchet 10. The second pawl 14 contacts the second ratchet 11 and restricts the second ratchet 11 from rotating counterclockwise. At this time, the distance between the second lever 18 and the second step 25 is very small. The second lever 18 is vertical and the bottom of the second lever 18 is below the second top surface 26. The first lever 16 is inclined and the bottom contacts the first top surface 24.

[0052] When cleaning the front drain pipe 1, the drive motor 40 is turned on. The drive motor 40 drives the drive chain 41 to rotate clockwise. The drive chain 41 drives the slider 4 to move towards the water inlet end of the front drain pipe 1. When the slider 4 moves close to the water inlet end of the front drain pipe 1, since the inner side of the upright plate 33 near the water inlet end of the front drain pipe 1 is at a certain distance from the drive plate 28, when the first baffle 30 just contacts the upright plate 33 and pushes the upright plate 33 to move towards the water outlet end of the front drain pipe 1, the upright plate 33 will not immediately contact the drive plate 28. Instead, it will first push the first baffle 30 to move towards the water outlet end of the front drain pipe 1. The first actuating plate 20 and the second actuating plate 21 slide towards the outlet end of the forward drain pipe 1. When the first actuating plate 20 and the second actuating plate 21 move towards the outlet end of the forward drain pipe 1, the bottom of the first lever 16 moves along the first top surface 24, and the second step 25 contacts the second lever 18 and pushes the second lever 18 to rotate counterclockwise, so that the bottom of the second lever 18 contacts the second top surface 26. The second lever 18 drives the second sleeve 17 and the second pawl 14 to rotate counterclockwise, so that the second pawl 14 separates from the second ratchet 11. As the slider 4 continues to move towards the inlet end of the forward drain pipe 1, The upright plate 33 contacts the drive plate 28 and pushes the drive plate 28 to move towards the outlet of the forward drain pipe 1. The rack 29 on the drive plate 28 drives the gear 19 to rotate counterclockwise. Since the second pawl 14 is separated from the second ratchet 11 at this time, the rotating shaft 8 can rotate counterclockwise. The rotating shaft 8 drives the support rod 5, the first ratchet 10 and the second ratchet 11 to rotate counterclockwise until the support rod 5 is vertical. While pushing the drive plate 28 to move, the upright plate 33 also drives the first actuating plate 20 and the second actuating plate 21 to move. As the support rod 5 rotates to a vertical position, the first... A lever 16 slides down the first step 22 from the first top surface 24, making the bottom of the lever 16 lower than the first top surface 24. At this time, the first pawl 13 will rotate rapidly counterclockwise under the action of gravity and spring, causing the first pawl 13 to contact the first ratchet 10. The first pawl 13 will restrict the clockwise rotation of the first ratchet 10, thereby restricting the clockwise rotation of the support rod 5. At this time, the support rod 5 will contact the lower end of the rotating groove 12. The rotating groove 12 restricts the support rod 5 from continuing to rotate counterclockwise, so the support rod 5 can only remain vertical. Figure 4 , Figure 7 and Figure 8 As shown. When the support rod 5 rotates to a vertical position, the drive motor 40 reverses and drives the drive chain 41 to rotate counterclockwise. The drive chain 41 drives the slider 4 to move towards the outlet of the front drain pipe 1. During the movement, the push plate 6 pushes the mud, sand and stones at the bottom of the front drain pipe 1 into the sedimentation tank 2. To better control the forward and reverse rotation and opening and closing of the rotary motor, we can install proximity switches on the inner side of the first baffle 30 and the inner side of the second baffle 31. When the housing 7 is a certain distance away from the first baffle 30 or the second baffle 31, the proximity switch will transmit a signal to the controller.

[0053] When slider 4 moves to the end near the outlet of front drain pipe 1, since the inner side of the upright plate 33 near the outlet of front drain pipe 1 is at a certain distance from the drive plate 28, when the second baffle 31 just contacts the upright plate 33 and pushes the upright plate 33 to move towards the inlet of front drain pipe 1, the upright plate 33 will not immediately contact the drive plate 28. Instead, it will first push the first actuating plate 20 and the second actuating plate 21 to slide towards the inlet of front drain pipe 1. When the first actuating plate 20 and the second actuating plate 21 move towards the inlet of front drain pipe 1, the bottom of the second lever 18 will slide along the second top surface 2. As the first step 22 moves, it contacts the first lever 16 and pushes the first lever 16 to rotate clockwise, causing the bottom of the first lever 16 to contact the first top surface 24. The first lever 16 drives the first sleeve 15 and the first pawl 13 to rotate clockwise, causing the first pawl 13 to separate from the first ratchet 10. As the upright plate 33 continues to move towards the outlet of the forward drain pipe 1, the inner side of the upright plate 33 contacts the drive plate 28 and pushes the drive plate 28 to move towards the inlet of the forward drain pipe 1. The rack 29 on the drive plate 28 drives the gear 19 to rotate clockwise. Since the first pawl 13 and the first ratchet 10 are moving clockwise, the first step 22 will contact the first lever 16 and push the first top surface 24. The first lever 16 will drive the first sleeve 15 and the first pawl 13 to rotate clockwise. With ratchet 10 disengaged, the rotating shaft 8 can rotate clockwise. The rotating shaft 8 drives the support rod 5, the first ratchet 10, and the second ratchet 11 to rotate clockwise until the support rod 5 is horizontal. The upright plate 33, while pushing the drive plate 28, also drives the first actuating plate 20 and the second actuating plate 21 to move. As the support rod 5 rotates to a horizontal position, the second actuating lever 18 slides down the second step 25 from the second top surface 26, making the bottom of the second actuating lever 18 lower than the second top surface 26. At this time, the second pawl 14, under the action of gravity and the spring, will rotate rapidly clockwise, causing the second pawl... When the pawl 14 contacts the second ratchet 11, the second pawl 14 restricts the counterclockwise rotation of the second ratchet 11, thereby restricting the counterclockwise rotation of the support rod 5. At this time, the support rod 5 will contact the upper end of the rotating groove 12. The rotating groove 12 restricts the support rod 5 from continuing to rotate clockwise, so the support rod 5 can only remain horizontal. As the support rod 5 rotates to a horizontal position, the proximity switch on the inner side of the second baffle 31 senses the housing and transmits the signal to the controller. The controller controls the drive motor 40 to stop rotating or reverse to drive the drive chain 41 to rotate clockwise.
