Description

Technical Field

[0001] This application relates to the field of garden drainage, and in particular to a garden drainage structure that can automatically adjust the flow rate. Background Technology

[0002] A garden drainage structure is a building structure installed along garden paths and connected to underground drainage pipes to promptly remove water accumulation on garden paths. Existing garden drainage structures are usually quite simple, typically consisting of drainage wells and manhole covers.

[0003] During daily use, due to the abundance of soil and rocks along garden paths, water often carries sand, gravel, and dead branches into the drainage wells during drainage. Over time, this leads to excessive accumulation of sand, gravel, and dead branches in the underground drainage pipes connected to the wells, causing blockages and affecting the stability of the garden's drainage structure. To address this, filter components are typically installed within the drainage structure to reduce the probability of sand, gravel, and dead branches flowing into the underground drainage pipes. In seasons with low rainfall, the reduced drainage demand does not significantly impact the stability of the garden's drainage structure. However, during seasons with high rainfall, the increased drainage demand does affect the stability of the drainage system to some extent.

[0004] Therefore, a garden drainage structure with automatically adjustable flow rate is proposed to solve some of the problems existing in the above-mentioned prior art. Summary of the Invention

[0005] The purpose of this application is to automatically adjust the drainage efficiency within a garden drainage structure according to actual needs, effectively improving the flexibility and stability of the garden drainage structure during actual use. Compared with existing technologies, this application provides a garden drainage structure with automatically adjustable flow rate, including a drainage well. A horizontally arranged connecting pipe is fixedly connected to the bottom of the drainage well. Symmetrically arranged support plates are fixedly installed on the inner walls of the left and right sides of the drainage well. A filter plate is placed between the two support plates, located above the connecting pipe. Numerous small holes are evenly distributed on the filter plate. The left and right support plates, together with the filter plate, divide the interior of the drainage well into upper and lower spaces. The bottom of the filter plate is slidably installed... There is a second filter plate that fits tightly against it, and the second filter plate also has many small holes evenly distributed on it. The small holes on the second filter plate are staggered and overlapped with the small holes on the first filter plate. A threaded cylinder is rotatably installed at the bottom center of the right support plate, and a screw rod fixedly connected to the second filter plate is rotatably installed inside the threaded cylinder. A waterproof chamber is fixedly installed on the outer end wall of the drainage well, and a servo motor and control panel are installed inside the waterproof chamber. A liquid level sensor is fixedly installed on the inner end wall of the drainage well and is vertically set above the support plate. The threaded cylinder is connected to the drive shaft of the servo motor, and the servo motor is electrically connected to the control panel. The top of the drainage well is covered with a well cover.

[0006] Furthermore, the middle position of filter plate one is set as a downwardly concave arc-shaped structure.

[0007] Furthermore, a storage battery is fixedly installed inside the waterproof compartment, and the storage battery is electrically connected to the control panel. Streetlights are installed around the drainage well, and the storage battery is electrically connected to the power supply of the streetlights. A trip device is connected between the storage battery and the power supply of the streetlights.

[0008] Furthermore, the manhole cover has symmetrical hinged movable doors on the left and right sides above two support plates, and a pull basket is placed below the movable doors above the support plates. The drainage well has a horizontally arranged screw body rotatably installed inside, and a screw sleeve is threaded onto the screw body. A scraper is fixedly installed on the screw sleeve and slidably set on the top of the connecting pipe. The bottom size of the scraper is adapted to the top size of the connecting pipe. The screw body is connected to the drive shaft of the servo motor.

[0009] Furthermore, the lead screw body is positioned inside the drainage well, above it, and close to the well cover.

[0010] Furthermore, a roller is rotatably mounted inside the scraper and located above the filter plate. The outer dimensions of the roller are adapted to the top dimensions of the filter plate. Extrusion blocks adapted to the small holes on the filter plate are evenly distributed on the outer end wall of the roller.

[0011] Furthermore, the manhole cover is movable and covers the top of the drainage well. A sleeve is fixedly installed on the inner wall of the right side of the drainage well, which is vertically set above the support plate. A threaded cylinder is rotatably installed at the bottom of the sleeve. The threaded cylinder is connected to the drive shaft of the servo motor. A screw rod is vertically extended into the sleeve through the internal thread of the threaded cylinder. A vertically set guide bar is fixedly installed on the inner wall of the sleeve. A groove that matches the guide bar is opened on the outer wall of the screw rod. A top rod located above the screw rod is movably inserted at the top of the sleeve, and the top rod is supported at the bottom of the manhole cover.

[0012] Furthermore, a spring is installed inside the sleeve to provide elastic support between the second screw and the push rod.

[0013] Furthermore, a screw chamber connected to the interior of the drainage well is fixedly installed on the outer end wall of the drainage well. The screw body and screw sleeve are located inside the screw chamber. A transmission chamber one and a transmission chamber two are fixedly connected in sequence below the screw chamber. A rotating shaft one, parallel to the screw body, is rotatably installed at the connection between the transmission chamber one and the transmission chamber two. The rotating shaft one is connected to the screw body via a transmission belt. A rotating shaft two, located on the same plane as the threaded cylinder one, is rotatably installed inside the lower part of the transmission chamber two. The rotating shaft two is connected to the rotating shaft one via a transmission belt. The rotating shaft two is fixedly connected to the drive shaft of the servo motor. A rotating shaft three, located on the same plane as the threaded cylinder two, is rotatably installed inside the lower part of the transmission chamber two. Meshing bevel gears are fixed to one end of the rotating shaft three near the threaded cylinder two and on the threaded cylinder two, respectively.

[0014] Furthermore, the top of transmission chamber one is connected to the inside of the screw chamber. A partition plate is fixedly installed at the connection between transmission chamber one and transmission chamber two, which is movably disposed on the outside of rotating shaft one. The partition plate is movably sealed to rotating shaft one. The lower end of transmission chamber two extends to the outside of threaded cylinder one. Threaded cylinder one, rotating shaft two and rotating shaft three are all movably sealed to transmission chamber two. The transmission belt is respectively disposed in transmission chamber one and transmission chamber two.

[0015] Compared to existing technologies, the advantages of this application are:

[0016] (1) This application divides the drainage well into upper and lower spaces by placing filter plate one on a support plate that is symmetrically fixed in the middle of the drainage well. A liquid level sensor for monitoring water level depth is installed in the upper space, and an adjustable filter plate two is slidably connected below the filter plate. This allows the garden drainage structure to improve the filtration effect of filter plate one and filter plate two when the rainfall is low, and improve the efficiency of rainwater flow through filter plate one and filter plate two when the rainfall is high. This makes it easy to flexibly adjust the rainwater flow efficiency in the garden drainage structure according to the actual situation, avoids a large amount of sand, gravel and dead branches from entering the underground drainage pipe under normal conditions, and avoids poor rainwater drainage when the rainfall is high, effectively improving the flexibility and stability of the garden drainage structure during operation.

[0017] (2) By setting the middle position of filter plate one to a downward concave arc shape, the height of the middle position of filter plate one is lower than the height of its front and rear sides, so that sand and gravel can stay at the top middle position of filter plate one, avoiding sand and gravel from staying at the edge of filter plate one, effectively improving the convenience of cleaning sand and gravel.

[0018] (3) By setting up a storage battery to power the control panel and servo motor, the power stability of the garden drainage structure is ensured. By connecting the trip switch between the street light power supply and the storage battery, the power connection between the external street light power supply and the storage battery can be interrupted in time under abnormal circumstances, which helps to prevent the power unit in the waterproof chamber from burning out due to abnormality, and further improves the stability and safety of the garden drainage structure.

[0019] (4) By controlling the scraper to move synchronously with the filter plate 2, the sand, gravel and dead branches accumulated on the top of the filter plate 1 can be cleaned in advance and placed on the baskets on both sides. Afterwards, it is only necessary to flip and open the movable door to lift the basket to clean the sand, gravel and dead branches. There is no need to frequently disassemble the filter plate 1, which effectively improves the convenience of cleaning sand, gravel and dead branches on the filter plate 1 in the garden drainage structure.

[0020] (5) By setting the screw body inside the drainage well and above the well cover, the screw body is positioned at a higher height, which reduces the probability of the screw body coming into contact with rainwater in the drainage well. This helps to reduce the probability of sand, gravel and dead branches in the rainwater getting tangled on the screw body, and prevents the screw body from being blocked or jammed, thus effectively improving the stability of the garden drainage structure during operation.

[0021] (6) By setting the outer dimension of the roller to match the top dimension of the filter plate, and assembling the roller with a pressing block that matches the small holes on the filter plate, the roller can roll on the top of the filter plate by matching and engaging with the numerous small holes on the filter plate. In the rolling process, the roller gradually presses the numerous small holes on the filter plate, further pressing and unblocking the numerous small holes on the filter plate, which helps to ensure the smooth flow of rainwater through the filter plate.

[0022] (7) By rotating the second threaded cylinder to the bottom of the sleeve and connecting the second screw to the inside of the second threaded cylinder, and with the matching and limiting of the guide strip and the slide groove, the rotating sleeve can control the second screw to rise, push the top rod to move up and open the manhole cover. This is beneficial to open the manhole cover significantly during rainy weather, increase the efficiency of rainwater entering the drainage well, and further improve the efficiency of drainage of surface water through the drainage structure.

[0023] (8) By installing the spring inside the sleeve to support between the screw and the top rod, the distance between the screw and the top rod can be relatively reduced after the top is subjected to excessive pressure, ensuring that the manhole cover is lowered and reset. This helps to avoid the impact on the operational stability of other components in the drainage structure when the top of the manhole cover is subjected to excessive pressure, and further improves the operational stability of the drainage structure.

[0024] (9) By connecting the transmission belts of shaft one, shaft two and shaft three, a single servo motor in the waterproof chamber can control the filter plate two, scraper and well cover, which effectively improves the correlation between the components in the drainage structure and effectively reduces the amount of servo motors used in the drainage structure, thereby reducing the cost of using the drainage structure to a certain extent.

[0025] (10) By inserting the first rotating shaft horizontally between the first and second transmission chambers and connecting the first transmission chamber to the screw chamber, and by setting up a partition to block the first and second transmission chambers, mud and water impurities can be prevented from entering the second transmission chamber through the first transmission chamber, which is conducive to ensuring the rotational stability of the first threaded cylinder, the second rotating shaft, the third rotating shaft and each transmission belt in the second transmission chamber.

[0041] Example 1

[0042] This invention provides a garden drainage structure with automatically adjustable flow rate. Please refer to [link / reference]. Figure 1 - Figure 12 The system includes a drainage well 1, with a horizontally connected connecting pipe 101 fixedly connected to the bottom of the drainage well 1. Symmetrically arranged support plates 102 are fixedly installed on the inner walls of the left and right sides of the drainage well 1. A filter plate 103, positioned above the connecting pipe 101, is placed between the two support plates 102. Numerous small holes are evenly distributed on the filter plate 103. The support plates 102, in conjunction with the filter plate 103, divide the interior of the drainage well 1 into upper and lower spaces. A second filter plate 104, which is slidably installed and tightly fitted to the bottom of the filter plate 103, is also evenly distributed with numerous small holes. The small holes on the filter plate 104 interact with the filter... The small holes on plate 103 are staggered and overlapping. A threaded cylinder 105 is rotatably installed at the bottom center of the right support plate 102. A screw 106, which is fixedly connected to filter plate 104, is rotatably installed inside the threaded cylinder 105. A waterproof chamber 107 is fixedly installed on the outer end wall of the drainage well 1. A servo motor and control panel are installed inside the waterproof chamber 107. A liquid level sensor 108 is fixedly installed on the inner end wall of the drainage well 1, which is vertically set above the support plate 102. The threaded cylinder 105 is connected to the drive shaft of the servo motor. The servo motor is electrically connected to the control panel. The top of the drainage well 1 is covered with a well cover 2.

[0043] During operation, the drainage structure has a drainage well 1 installed below ground level along the garden path, connected to an underground drainage pipe via a connecting pipe 101. The top of the well cover 2 is flush with the garden path and is designed as a large-pore grid structure. Normally, when the drainage volume is small, a small amount of rainwater enters the drainage well 1 through the well cover 2. Due to the staggered and overlapping of numerous small holes on filter plates 103 and 104, the combined filtration by filter plates 103 and 104 is more thorough. As the rainwater flows downwards... The sand, gravel, and dead branches carried by the rainwater are blocked by filter plate 103 and filter plate 204, and remain on top of filter plate 103. Later, the staff can lift and remove filter plate 103 to clean the sand, gravel, and dead branches accumulated on it regularly. The small amount of rainwater after being filtered will continue to flow downward through filter plate 103 and filter plate 204, and enter the lower space inside the drainage well 1. It will then enter the underground drainage pipe through the connecting pipe 101, ensuring the smooth flow of a small amount of rainwater in the garden drainage structure under normal conditions.

[0044] When there is heavy rainfall during the plum rain season, a large amount of rainwater enters the upper space inside the drainage well 1. Initially, the efficiency of rainwater entering the upper space inside the drainage well 1 is greater than the efficiency of rainwater flowing downward from the overlapping position of filter plate 103 and filter plate 104. This causes rainwater to gradually accumulate in the upper space inside the drainage well 1. At this time, the liquid level sensor 108 installed in the drainage well 1 will monitor the depth of rainwater in the upper space inside the drainage well 1.

[0045] When the liquid level sensor 108 detects that the rainwater accumulation in the upper space of the drainage well 1 is too large, it will transmit the relevant signal to the control panel in the waterproof compartment 107. Then, the control panel controls the servo motor to be powered on and started, which drives the threaded cylinder 105 connected to its drive shaft to rotate. With the meshing between the threaded cylinder 105 and the screw 106, the position of the filter plate 104 is adjusted, so that the numerous small holes on the filter plate 104 are gradually aligned with the numerous small holes on the filter plate 103, thereby increasing the filtration pore size of the structure formed by the filter plate 103 and the filter plate 104 and reducing its filtration effect.

[0046] By increasing the efficiency of water flow through filter plate 103 and filter plate 204, rainwater can flow through the garden drainage structure more efficiently and quickly and enter the underground drainage pipe. The scale of the movement adjustment of filter plate 204 relative to filter plate 103 can be set in association with the amount of water accumulated in the upper space of the drainage well 1 monitored by the liquid level sensor 108.

[0047] This application divides the drainage well 1 into upper and lower spaces by mounting filter plate 103 symmetrically on a support plate 102 fixed in the middle of the drainage well 1. A level sensor 108 for monitoring water level is installed in the upper space, and an adjustable filter plate 104 is slidably connected under filter plate 103. This allows the garden drainage structure to improve the filtration effect of filter plate 103 and filter plate 104 when rainfall is low, and improve the efficiency of rainwater flow through filter plate 103 and filter plate 104 when rainfall is high. This facilitates flexible adjustment of the rainwater flow efficiency within the garden drainage structure according to actual conditions, preventing a large amount of sand, gravel, and dead branches from entering the underground drainage pipes under normal conditions, and avoiding poor drainage during heavy rainfall. This effectively improves the flexibility and stability of the garden drainage structure during operation.

[0048] Please see Figure 1 and Figure 4 The middle position of filter plate 103 is designed as a downwardly concave arc shape. During the operation of this drainage structure, because the middle position of filter plate 103 is designed as a downwardly concave arc shape, the height of the middle position of filter plate 103 is lower than the height of its front and rear sides. When sand, gravel and dead branches that are carried by rainwater are intercepted at the top of filter plate 103, under the action of gravity and the guidance formed by the arc surface of the top of filter plate 103, the sand, gravel and dead branches will stay at the top middle position of filter plate 103. This can prevent sand, gravel and dead branches from staying at the edge of filter plate 103 and effectively improve the convenience of cleaning sand, gravel and dead branches.

[0049] Please see Figure 11 and Figure 12 The waterproof chamber 107 is also equipped with a battery, which is electrically connected to the control panel. Streetlights are installed around the drainage well 1, and the battery is electrically connected to the power supply of the streetlights. A trip device is connected between the battery and the power supply of the streetlights. During the operation of this drainage structure, the surrounding streetlights can provide power support to the control panel and servo motor inside the waterproof chamber 107. Under normal conditions, the power supply of the streetlights stores electrical energy in the battery inside the waterproof chamber 107, and then supplies power to the control panel and servo motor through the battery, ensuring the stability of the power supply in the garden drainage structure.

[0050] Because it is equipped with a battery, it can temporarily store a certain amount of electrical energy. Even if the power supply to the streetlights is interrupted, the garden drainage structure can still be used normally, effectively ensuring the operational stability of the device during long-term use. By connecting the trip circuit breaker between the streetlight power supply and the battery, the power connection between the external streetlight power supply and the battery can be interrupted in time under abnormal circumstances. This helps to prevent the power unit in the waterproof compartment 107 from burning out due to abnormalities, further improving the stability and safety of the garden drainage structure.

[0051] Please see Figure 1 and Figure 3 The manhole cover 2 has symmetrical hinged movable doors 201 on the left and right sides inside, located above two support plates 102. A pull basket 3 is placed below the movable doors 201 and located above the support plates 102. A horizontally arranged screw body 301 is rotatably installed inside the drainage well 1. A screw sleeve 302 is threaded onto the screw body 301. A scraper 303 is fixedly installed on the screw sleeve 302 and slidably disposed on the top of the connecting pipe 101. The bottom dimension of the scraper 303 is adapted to the top dimension of the connecting pipe 101. The screw body 301 is connected to the drive shaft of the servo motor.

[0052] During the operation of this drainage structure, when the rainwater flow is too large and causes the filter plate 104 to move and adjust, the servo motor will synchronously drive the lead screw body 301 to rotate. Through the threaded connection between the lead screw body 301 and the lead screw sleeve 302, the lead screw sleeve 302 drives the scraper 303 to move on the top of the filter plate 103. During the movement, adjustment and reset of the filter plate 104, the scraper 303 is synchronously driven to move to one side and then reset. During this process, the movement of the scraper 303 pushes the sand, gravel and dead branches accumulated on the top of the filter plate 103 to the pull baskets 3 on the two side support plates 102. Subsequently, the movable door 201 can be flipped open to remove the pull basket 3 placed below and clean the sand, gravel and dead branches on the pull basket 3.

[0053] In this application, by controlling the scraper 303 to move synchronously with the filter plate 104, the sand, gravel and dead branches accumulated on the top of the filter plate 103 can be pre-cleaned onto the baskets 3 on both sides. Subsequently, it is only necessary to flip and open the movable door 201 to lift the baskets 3 to clean the sand, gravel and dead branches. There is no need to frequently disassemble the filter plate 103, which effectively improves the convenience of cleaning sand, gravel and dead branches on the filter plate 103 in the garden drainage structure.

[0054] Please see Figure 1 and Figure 3 The lead screw body 301 is positioned inside the drainage well 1, above and close to the well cover 2. During operation, the lead screw body 301 is positioned high inside the drainage well 1, near the well cover 2. This reduces the probability of the lead screw body 301 coming into contact with rainwater in the drainage well 1, thus reducing the likelihood of sand, gravel, and dead branches getting tangled in the lead screw body 301 and preventing it from becoming blocked or jammed. This effectively improves the stability of the garden drainage structure during operation.

[0055] Please see Figure 4 , Figure 7 and Figure 9Inside the scraper 303, a roller 304 is rotatably mounted on the top of the filter plate 103. The outer dimensions of the roller 304 are adapted to the top dimensions of the filter plate 103. The outer end wall of the roller 304 is evenly distributed with extrusion blocks 305 that are adapted to the small holes on the filter plate 103. During the operation of this drainage structure, when the scraper 303 moves to clean the sand, gravel and dead branches on the top of the filter plate 103, it will drive the roller 304 to move synchronously.

[0056] Since the outer dimensions of the roller 304 are adapted to the top dimensions of the filter plate 103, and the outer end wall of the roller 304 is fitted with a pressing block 305 that is adapted to the small holes on the filter plate 103, when the roller 304 moves with the scraper 303, the pressing block 305 and the numerous small holes on the filter plate 103 are adapted to and engaged, causing the roller 304 to roll on the top of the filter plate 103. During the rolling process of the roller 304, the pressing block 305 fixed on its outer end wall gradually presses into the numerous small holes on the filter plate 103, further pressing and unblocking the numerous small holes on the filter plate 103, which helps to ensure the smooth flow of rainwater through the filter plate 103.

[0057] Please see Figure 5 - Figure 7 and Figure 9 - Figure 10 The manhole cover 2 is movable and covers the top of the drainage well 1. A sleeve 4 is fixedly installed on the inner wall of the right side of the drainage well 1, which is vertically set above the support plate 102. A threaded cylinder 401 is rotatably installed at the bottom of the sleeve 4. The threaded cylinder 401 is connected to the drive shaft of the servo motor. A screw 402 extending vertically into the sleeve 4 is connected to the internal thread of the threaded cylinder 401. A vertically set guide strip 403 is fixedly installed on the inner wall of the sleeve 4. A groove 404 adapted to the guide strip 403 is opened on the outer wall of the screw 402. A top rod 405 located above the screw 402 is movably inserted at the top of the sleeve 4, and the top rod 405 is supported at the bottom of the manhole cover 2.

[0058] During the operation of this drainage structure, when there is excessive rainfall requiring rapid drainage, the servo motor drives the first threaded cylinder 105 to rotate, which in turn synchronously drives the second threaded cylinder 401 to rotate. Due to the sliding fit between the vertically fixed guide bar 403 on the inner end wall of the sleeve 4 and the sliding groove 404 on the second threaded cylinder 401, the second screw 402 can only move up and down within the sleeve 4, preventing relative rotation of the second screw 402 within the sleeve 4. This avoids the second screw 402 from rotating synchronously with the second threaded cylinder 401 during its rotation. At this time, the second threaded cylinder 401 and the screw... The threaded connection between the two 402s can drive the threaded cylinder 401 to move upward inside the sleeve 4, pushing the top rod 405 upward to lift the manhole cover 2. This can significantly open the manhole cover 2, increasing the efficiency of rainwater entering the drainage well 1. This is beneficial for further improving the drainage efficiency of the drainage structure for road surface water during heavy rainfall. When the filter plate 104 is reset, the threaded cylinder 401 is simultaneously reversed, causing the screw 402 to move downward. At this time, the top rod 405 at the bottom of the manhole cover 2 moves downward and loses its support, ensuring that the manhole cover 2 automatically resets after the amount of rainwater decreases. This is beneficial for the normal and cyclical use of the drainage structure.

[0059] The sleeve 4 is equipped with a spring that provides elastic support between the screw 402 and the push rod 405. During the operation of this drainage structure, since the spring is installed inside the sleeve 4 and supported between the screw 402 and the push rod 405, when the screw 402 moves upward, it pushes the spring upward, which in turn pushes the push rod 405 upward, thus pushing the manhole cover 2 to open. When the manhole cover 2 is pressed down by a heavy object, the spring will be compressed and contracted under the pressure. Even when the filter plate 104 moves and aligns with the small hole inside the filter plate 103, the manhole cover 2 can still return to its original position downward, preventing the top of the manhole cover 2 from being subjected to excessive pressure and affecting the operational stability of other components in the drainage structure.

[0060] This application installs a spring inside the sleeve 4 to support the screw 402 and the top rod 405. This allows the distance between the screw 402 and the top rod 405 to relatively shrink after excessive pressure is applied to the top, ensuring that the manhole cover 2 can be lowered and reset. This helps to avoid the impact of excessive pressure on the top of the manhole cover 2 on the operational stability of other components in the drainage structure, and further improves the operational stability of the drainage structure.

[0061] Please see Figure 5 and Figure 6A screw chamber 5, communicating with the interior of the drainage well 1, is fixedly installed on the outer end wall of the drainage well 1. The screw body 301 and screw sleeve 302 are located inside the screw chamber 5. Below the screw chamber 5, a transmission chamber 1 501 and a transmission chamber 2 502 are sequentially fixedly connected. A rotating shaft 1 503, parallel to the screw body 301, is rotatably installed at the connection between the transmission chamber 1 501 and the transmission chamber 2 502. The rotating shaft 1 503 is connected to the screw body 301 via a transmission belt. The transmission chamber 2 502... Inside the lower part of the transmission chamber 502, a rotating shaft 504 is rotatably mounted on the same plane as the threaded cylinder 105. The rotating shaft 504 and the rotating shaft 103 are connected by a transmission belt. The rotating shaft 504 is fixedly connected to the drive shaft of the servo motor. Inside the lower part of the transmission chamber 502, a rotating shaft 505 is rotatably mounted on the same plane as the threaded cylinder 201. The end of the rotating shaft 505 near the threaded cylinder 201 and the threaded cylinder 201 are respectively fixed with meshing bevel gears 506.

[0062] During operation, the drainage structure requires only a single servo motor within the waterproof chamber 107 to drive the rotation of the threaded cylinder 105, the lead screw body 301, and the threaded cylinder 401. In actual operation, the servo motor within the waterproof chamber 107 is powered on and starts, driving the rotating shaft 504, which is fixedly connected to its drive shaft, to rotate. Subsequently, through the transmission belt, the threaded cylinder 105 is driven to rotate. With the meshing of the threaded cylinder 105 and the lead screw 106, the lead screw 106 is driven to move the filter plate 104, thus performing related control.

[0063] Simultaneously, through the transmission connection of the other side transmission belt, the second rotating shaft 504 drives the first rotating shaft 503 to rotate. Then, through the transmission connection of another transmission belt, the first rotating shaft 503 drives the lead screw body 301 to rotate. With the meshing of the lead screw body 301 and the lead screw sleeve 302, the lead screw sleeve 302 drives the scraper 303 to move, cleaning the sand, gravel and dead branches on the top of the filter plate 103.

[0064] Synchronously, through the transmission belt, the second shaft 504 drives the third shaft 505 to rotate. Through the meshing transmission between the bevel gear 506 at its end and the bevel gear 506 on the second threaded cylinder 401, the second threaded cylinder 401 is driven to rotate. With the help of the threaded meshing between the second threaded cylinder 401 and the second screw 402, the second screw 402 is driven to move upward inside the sleeve 4, pushing the top rod 405 upward and opening the well cover 2.

[0065] In this application, by using the drive connection of rotating shaft 1 503, rotating shaft 2 504 and rotating shaft 3 505 in conjunction with the various drive belts, a single servo motor in the waterproof chamber 107 can control the filter plate 2 104, the scraper 303 and the manhole cover 2, which effectively improves the correlation between the various components in the drainage structure and effectively reduces the number of servo motors used in the drainage structure, thereby reducing the usage cost of the drainage structure to a certain extent.

[0066] Please see Figure 8 and Figure 9 The top of transmission chamber 1 501 is connected to the inside of screw chamber 5. A partition plate is fixedly installed at the connection between transmission chamber 1 501 and transmission chamber 2 502, which is movably disposed on the outside of shaft 1 503. The partition plate is movably sealed to shaft 1 503. The lower end of transmission chamber 2 502 extends to the outside of threaded cylinder 1 105. Threaded cylinder 1 105, shaft 2 504 and shaft 3 505 are all movably sealed to transmission chamber 2 502. The transmission belt is respectively disposed in transmission chamber 1 501 and transmission chamber 2 502.

[0067] During operation, the drainage structure, by transversely inserting the rotating shaft 503 between the transmission chamber 501 and the transmission chamber 502, and by connecting the transmission chamber 501 to the screw chamber 5, and by using a partition to block the passage between the transmission chamber 501 and the transmission chamber 502, can prevent mud and water impurities from entering the transmission chamber 502 through the transmission chamber 501. This helps to ensure the rotational stability of the threaded cylinder 105, the rotating shaft 504, the rotating shaft 505, and the various transmission belts in the transmission chamber 502.

[0068] The above are merely the best implementation methods adopted in this application in light of current practical needs, but the scope of protection of this application is not limited thereto.
