[0008] By adopting the above technical solution, when it rains, the rainwater grate intercepts larger solid waste, and the water flow drives the dirt through the rainwater grate and flows into the rainwater well. The screening component screens the dirt step by step, and then the dirt screened by the screening component is pushed to the dumping port through the cleaning mechanism. The dirt enters the collecting box through the dumping port, and the sieved dirt is collected while maintaining the filtering effect of the screening component. When the dirt needs to be cleaned, the staff opens the cover, takes out the collecting box and replaces it with a new one. There is no need for the staff to use cleaning tools to enter the rainwater well to clean the dirt, which makes it convenient for the staff to clean the dirt in the rainwater well.
[0009] Optionally, the screening assembly includes a plurality of filter plates for filtering dirt, the plurality of filter plates are arranged in sequence along a vertical direction, and the diameters of the filter holes of the plurality of filter plates decrease step by step from top to bottom, and adjacent filter plates are parallel to each other;
[0010] The cleaning mechanism includes a scraping assembly for abutting the filter plate and a starting assembly for synchronously adjusting the distance between two adjacent filter plates. The filter plates correspond to the scraping assemblies one by one. When two adjacent filter plates approach each other, the scraping assembly abuts against one side of the corresponding filter plate and moves toward the pouring port.
[0011] By adopting the above technical scheme, the water flow drives the dirt through the rainwater grate and flows into the rainwater well. The filter plates filter the dirt brought into the rainwater well by the water flow step by step. The filtered dirt accumulates on the filter plates, and then the distance between the two adjacent filter plates is synchronously adjusted by the starting component so that the two adjacent filter plates are close to each other. The scraping component presses against one side of the filter plate to push the dirt to the pouring port, so as to clean the dirt accumulated on the filter plate and push the cleaned dirt into the collection box. When the collection box is full of dirt, the staff opens the cover, takes out the collection box and replaces it with a new one. There is no need for the staff to enter the rainwater well to clean the dirt, which makes it convenient for the staff to clean the dirt in the rainwater well.

[0013] The water storage bucket is rotatably arranged on the top of the movable frame, and the opening of the water storage bucket faces upward, and the trigger member is located between the movable frame and the fixed frame. When the movable frame descends until the trigger member abuts against the water storage bucket, the movable frame continues to descend, and the trigger member pushes the water storage bucket to flip over.
[0014] By adopting the above technical scheme, when it rains, the water storage bucket opens upward and receives rainwater. As the amount of rainwater in the water storage bucket increases, the water storage bucket and the movable frame move downward, and the filter plate is driven to move under the action of the scissor arms, and the two adjacent filter plates approach each other. The cleaning component abuts against one side of the filter plate to push the dirt to the dumping port. After the water storage bucket moves downward until it abuts against the trigger member, the trigger member pushes the water storage bucket to flip over, so that the water storage bucket pours out the received rainwater. Under the action of the gravity of the filter plates, the filter plates move away from the fixed frame, and the two adjacent filter plates move back to each other. At the same time, under the action of the scissor arms, the movable frame drives the water storage bucket upward, and the water storage bucket returns to the normal position under the action of gravity, and starts to receive rainwater again, so as to intermittently clean the dirt accumulated on the filter plate while draining the rainwater well, thereby reducing the possibility of clogging of the filter plate due to the increasing accumulation of dirt.
[0015] Optionally, the scraping assembly includes a cleaning brush and a spring sheet, one side of the spring sheet is fixed above the corresponding filter plate, and the other side is connected to the cleaning brush, and the side of the cleaning brush facing away from the spring sheet abuts against the corresponding filter plate.
[0016] By adopting the above technical solution, when the two filter plates approach each other, the spring sheet bends and pushes the cleaning brush to move toward the corresponding pouring port, and the cleaning brush pushes the dirt accumulated on the filter plate to the pouring port, thereby cleaning the dirt accumulated on the filter plate, which is beneficial to reduce the possibility of clogging of the filter plate due to the increasing accumulation of dirt.
[0017] Optionally, a plurality of partition plates are provided in the collection box, and the plurality of partition plates and the inner wall of the collection box form a plurality of storage cavities, the storage cavities correspond one-to-one to the pouring ports, and a baffle for covering the pouring ports is slidably provided at the pouring ports. A plurality of control components are provided on the collection box, and the control components correspond one-to-one to the filter plates. When two adjacent filter plates approach each other, the filter plates push the corresponding control components, and the control components push the baffles away from the pouring ports.
[0018] By adopting the above technical solution, when two adjacent filter plates approach each other, the filter plates push the corresponding control components, and the control components push the baffle away from the pouring port, so that the dirt can enter the storage cavity through the pouring port, thereby realizing the classification and collection of the dirt filtered on different filter plates, which is convenient for the staff to subsequently process the dirt according to the volume of the dirt.
[0019] Optionally, the control assembly includes a return spring, a lever and a pull rope, the lever is slidably arranged on a side of the collection box facing the filter plate, one end of the pull rope is connected to the lever, and the other end is connected to the baffle, one end of the return spring is connected to the collection box, and the other end is connected to the baffle, and the return spring is used to pull the baffle to cover the pouring port corresponding to the cover;
[0020] When two adjacent filter plates are close to each other, the filter plates push the corresponding levers upward, and the pull ropes pull the baffles away from the pouring opening.
[0021] By adopting the above technical solution, when two adjacent filter plates are close to each other, the filter plates push the lever upward, and the lever upward pulls the pull rope, so that the pull rope drives the baffle plate downward and stretches the reset spring. After the baffle plate moves downward, the dirt can enter the corresponding storage chamber through the dumping port. When the two adjacent filter plates move back to back, the filter plates move away from the lever, and the reset spring pulls the baffle plate upward to cover the dumping port, reducing the possibility of dirt flowing into the receiving chamber through the dumping port without being filtered step by step, which is beneficial to the classification and collection of dirt and the subsequent treatment of the dirt in the collection box by the staff.
[0022] Optionally, a reminder spring for supporting the collection box is provided in the storage groove, a control switch is also provided in the storage groove, and a reminder light for power on is provided in the rainwater outlet, the reminder light is electrically connected to the control switch, and when the collection box is full of dirt, the collection box presses the control switch.
[0023] By adopting the above technical solution, when the collection box contains dirt, the overall weight of the collection box increases, the collection box compresses the prompt spring and moves toward the control switch, and when the collection box is full of dirt, the collection box presses the control switch, and the control switch turns on the prompt light, thereby promptly reminding the staff that the collection box needs to be replaced, which is beneficial to reduce the possibility of clogging the rainwater well due to failure to replace the collection box in time after it is full of dirt.
[0024] Optionally, a sliding rod is fixed in the storage groove, the sliding rod is vertically arranged, the prompt spring is sleeved on the sliding rod, a limiting ring is slidably sleeved on the sliding rod, a retaining ring is provided on the top of the sliding rod for limiting the limiting ring from separating from the sliding rod, and a clearance hole for the retaining ring to extend into is opened on the bottom wall of the collection box, the outer diameter of the limiting ring is larger than the aperture of the clearance hole, and when the limiting ring is against the retaining ring, the prompt spring is in a compressed state.
[0025] By adopting the above technical scheme, the retaining ring forms an upward limiting effect on the limit ring, and the limit ring keeps the prompt spring on the slide rod in a compressed state. When there is no dirt in the collection box, the elastic force provided by the prompt spring is greater than the gravity of the collection box, and the prompt spring presses the limit ring against the retaining ring. When the dirt collected in the collection box is equal to the elastic force of the prompt spring, the limit ring begins to compress the prompt spring. At this time, the collection box continues to collect dirt while the collection box moves downward and causes the limit ring to further compress the prompt spring. The collection box compresses the prompt spring and presses the control switch at the same time, so that the height of the collection box is kept unchanged from the time when there is no dirt in the collection box to the time when the collection box is about to be full of dirt, and the height of the pouring port is kept unchanged, which is beneficial for the cleaning mechanism to push the dirt on the filter plate into the collection box through the corresponding pouring port when cleaning the dirt.
[0026] Optionally, the side wall of the rainwater well is provided with a diversion groove for receiving the water flow dumped from the water storage bucket, the diversion groove is connected to a plurality of diversion holes, the diversion holes are arranged in a one-to-one correspondence with the dumping port, and the end of the diversion hole away from the diversion groove passes through the side wall of the rainwater well and faces the corresponding dumping port.
[0027] By adopting the above technical solution, the diversion groove can guide the water dumped from the water storage bucket into the diversion hole, and the diversion hole diverts the water flow in the diversion groove to the corresponding filter plate, thereby flushing the filter plate and the cleaning brush, which is beneficial to reduce the dirt attached to the filter plate and the cleaning brush.
[0028] Optionally, a diverter plate for guiding dirt away from the top of the water storage bucket is provided above the water storage bucket, and a plurality of water holes are opened on the diverter plate.
[0029] By adopting the above technical solution, when rainwater brings dirt into the rainwater well, it first falls on the diversion plate. The diversion plate guides the dirt away from the top of the water storage bucket. The rainwater flows into the water storage bucket through the water hole, reducing the dirt that enters the water storage bucket when the water storage bucket receives rainwater.
[0030] In summary, the present application includes at least one of the following beneficial technical effects:
[0031] When it rains, the rainwater grate intercepts larger solid waste, and the water flow drives the waste through the rainwater grate and flows into the rainwater well. The screening component screens the waste step by step, and then the cleaning mechanism pushes the screened waste to the dumping port. The waste enters the collection box through the dumping port, and the screened waste is collected while maintaining the filtering effect of the screening component. When the waste needs to be cleaned, the staff opens the cover, takes out the collection box and replaces it with a new one. The staff does not need to enter the rainwater well to clean the waste, which is convenient for the staff to clean the waste in the rainwater well.
[0032] When two adjacent filter plates are close to each other, the filter plates push the corresponding control components, and the control components push the baffle away from the dumping port, so that the dirt can enter the storage cavity through the dumping port, and the dirt filtered on different filter plates can be classified and collected, which is convenient for the staff to handle the dirt according to the volume of the dirt later;

When there is no dirt in the collection box, the elastic force provided by the prompt spring is greater than the gravity of the collection box, and the prompt spring presses the limit ring against the retaining ring. When the dirt collected in the collection box is equal to the elastic force of the prompt spring, the limit ring begins to compress the prompt spring. At this time, the collection box continues to collect dirt while the collection box moves downward and causes the limit ring to further compress the prompt spring. The collection box compresses the prompt spring and presses the control switch at the same time, so as to keep the height of the collection box unchanged from the time when there is no dirt in the collection box to the time when the collection box is about to be full of dirt, thereby keeping the height of the pouring port unchanged.

DETAILED DESCRIPTION
[0042] The following is combined with Figure 1-7 This application is described in further detail.
[0043] The present application embodiment discloses a sewage interception rainwater outlet. Figure 1 and Figure 2 A sewage intercepting rainwater outlet comprises a rainwater well 1, the top of which passes through the ground and is covered with a rainwater grate 11, which can intercept larger solid waste. A water outlet 15 for connecting a drainage pipe is provided on the side wall of the rainwater well 1. A receiving groove 12 is provided on the side wall of the rainwater well 1, and a collecting box 2 is installed in the receiving groove 12. The top of the receiving groove 12 passes through the ground and is covered with a cover plate 121. A pull rod 23 is fixed to the top wall of the collecting box 2. The pull rod 23 is vertically arranged, and the top of the pull rod 23 extends to the notch of the receiving groove 12. The staff can take out or install the collecting box 2 through the pull rod 23, which is convenient for the staff to replace the collecting box 2.
[0044] A screening assembly 3 is provided in the rainwater well 1. The screening assembly 3 is located above the water outlet 15. The screening assembly 3 is used to screen the dirt step by step. A plurality of pouring ports 25 for the dirt to pass through are provided on the side of the collection box 2 facing the screening assembly 3. A plurality of leakage holes 24 are provided on the side wall of the collection box 2. A filter screen 241 is installed in the leakage holes 24. A cleaning mechanism is provided in the rainwater well 1. The cleaning mechanism is used to scrape the dirt on the screening assembly 3 toward the pouring port 25.
[0045] When it rains, the water flow drives the dirt through the rainwater grate 11 and flows into the rainwater well 1. The screening component 3 screens the dirt step by step, and then the dirt screened by the screening component 3 is pushed to the pouring port 25 through the cleaning mechanism. The dirt enters the collecting box 2 through the pouring port 25, and the screened dirt is collected while maintaining the filtering effect of the screening component 3. When the dirt needs to be cleaned, the staff opens the cover 121, takes out the collecting box 2 and replaces it with a new collecting box 2. There is no need for the staff to enter the rainwater well 1 to clean the dirt, which makes it convenient for the staff to clean the dirt in the rainwater well 1.
[0046] Reference Figure 2 The screening assembly 3 includes a plurality of filter plates 31 for filtering dirt. In the embodiment of the present application, the number of the filter plates 31 is set to three. The three filter plates 31 are arranged in sequence along the vertical direction, and the diameters of the filter holes of the three filter plates 31 decrease step by step from top to bottom. The three filter plates 31 are all arranged horizontally, and the filter plates 31 are slidably arranged in the rainwater well 1, and the filter plates 31 slide along the vertical direction.
[0047] The cleaning mechanism includes a scraping assembly 4 and a starting assembly 5 . The filter plates 31 correspond to the scraping assemblies 4 one by one. When two adjacent filter plates 31 approach each other, the scraping assembly 4 abuts against one side of the corresponding filter plate 31 and moves toward the pouring port 25 .
[0048] Reference Figure 3 and Figure 4 The start assembly 5 includes a fixed frame 51, a moving frame 52, a water storage bucket 53, a trigger and a pair of scissor arms 54. The periphery of the fixed frame 51 is fixed to the side wall of the rainwater well 1, and the fixed frame 51 is located directly above the filter plate 31. The moving frame 52 is slidably arranged on the side wall of the rainwater well 1, and the moving frame 52 slides in the vertical direction, and the moving frame 52 is located directly above the fixed frame 51. The moving frame 52, the fixed frame 51 and the three filter plates 31 are all connected by a pair of scissor arms 54, and the hinge points of the scissor arms 54 are slidably connected to the moving frame 52, the fixed frame 51 and the filter plate 31 in sequence from top to bottom.
[0049] Two vertical poles are arranged opposite to each other on the top of the moving frame 52, and the vertical poles are arranged vertically. The water storage bucket 53 is rotatably arranged between the two vertical poles, and the opening of the water storage bucket 53 faces upward. A shifting block 531 is fixed to the side wall of the water storage bucket 53, and a triggering member is located between the moving frame 52 and the fixed frame 51. The triggering member is arranged as a triggering rod 55, and the triggering rod 55 is fixed on the side wall of the rainwater well 1. The triggering rod 55 is arranged vertically and is located directly below the shifting block 531. When the moving frame 52 moves downward until the triggering rod 55 touches the block, the moving frame 52 continues to move downward, and the triggering rod 55 pushes the water storage bucket 53 to flip.
[0050] When it rains, the water storage bucket 53 opens upward and receives rainwater. As the amount of rainwater in the water storage bucket 53 increases, the water storage bucket 53 and the movable frame 52 move downward, and the filter plates 31 move upward under the action of the scissor arms 54, and the two adjacent filter plates 31 move closer to each other. The cleaning and scraping assembly 4 abuts against one side of the filter plate 31 to push the dirt toward the dumping port 25. After the water storage bucket 53 moves downward until the shifting block 531 abuts against the triggering rod 55, the triggering rod 55 pushes the shifting block 531 to drive the water storage bucket 53 to flip, so that the water storage bucket 53 3 pours out the received rainwater. Under the gravity of the filter plates 31, the filter plates 31 move away from the fixed frame 51, and the two adjacent filter plates 31 move back to each other. At the same time, under the action of the scissor arms 54, the movable frame 52 drives the water storage bucket 53 upward. The water storage bucket 53 returns to the normal position under the action of gravity and starts to receive rainwater again, so that the dirt accumulated on the filter plates 31 is intermittently cleaned while the rainwater well 1 is drained, thereby reducing the possibility of the filter plates 31 being blocked due to the increasing amount of accumulated dirt.
[0051] Reference Figure 3 and Figure 4 The scraping assembly 4 includes a cleaning brush 42 and a spring sheet 41. The spring sheet 41 is in a U-shaped shape. One side of the spring sheet 41 is fixed to the top of the corresponding filter plate 31, and the other side is connected to the top of the cleaning brush 42. The bottom of the cleaning brush 42 is inclined toward the side of the collection box 2 and abuts against the corresponding filter plate 31. In the embodiment of the present application, the top of the highest spring sheet 41 is fixed to the bottom wall of the fixing frame 51, and the tops of the remaining spring sheets 41 are fixed to the bottom wall of the filter plate 31 opposite to the top of the spring sheet 41.
[0052] When the two filter plates 31 are close to each other, the spring sheet 41 bends and pushes the cleaning brush 42 to move toward the corresponding pouring port 25. The cleaning brush 42 pushes the dirt accumulated on the filter plate 31 toward the pouring port 25, thereby cleaning the dirt accumulated on the filter plate 31, which is beneficial to reduce the possibility of clogging of the filter plate 31 due to the increasing accumulation of dirt. When the water storage bucket 53 pours out the received rainwater, the elastic force of the spring sheet 41 can push the corresponding filter plate 31 away from the fixed frame 51 to achieve auxiliary pushing of the moving frame 52 upward.
[0053] Reference Figure 4 and Figure 5 The side wall of the rainwater well 1 is provided with a guide groove 13, and the guide groove 13 is located on the side of the water storage bucket 53 away from the storage box. The side wall of the rainwater well 1 is provided with a plurality of guide holes 131, and the guide holes 131 correspond to the pouring ports 25 one by one. The bottoms of the three guide holes 131 are all connected to the guide groove 13. The guide groove 13 can guide the water poured from the water storage bucket 53 into the guide holes 131, and the guide holes 131 divert the water flow in the guide groove 13 to the corresponding filter plate 31, so as to flush the filter plate 31 and the cleaning brush 42, which is conducive to reducing the dirt attached to the filter plate 31 and the cleaning brush 42.
[0054] A diverter plate 14 is fixed above the water storage bucket 53. The diverter plate 14 is adapted to cover the opening of the water storage bucket 53. The longitudinal section of the diverter plate 14 is inverted V-shaped. A plurality of water holes 141 are provided on the diverter plate 14. When rainwater brings dirt into the rainwater well 1, it first falls on the diverter plate 14. The diverter plate 14 guides the dirt away from the top of the water storage bucket 53. The rainwater flows into the water storage bucket 53 through the water holes 141, which reduces the dirt that enters the water storage bucket 53 when the water storage bucket 53 receives rainwater, and is conducive to maintaining the water storage capacity of the water storage bucket 53.
[0055] Reference Figure 3 and Figure 4 , a plurality of partition plates 21 are arranged in the collection box 2. In the embodiment of the present application, the number of the partition plates 21 is set to two. The inner wall of the collection box 2 formed by the two partition plates 21 forms a plurality of storage cavities 22, and the storage cavities 22 correspond to the pouring openings 25 one by one. The collection box 2 is fixed with a vertical plate 27 at each pouring opening 25. The vertical plate 27 is provided with a baffle 26 sliding toward the side wall of the storage cavity 22, and the baffle 26 is used to cover the pouring opening 25. A control component 6 is arranged on the vertical plate 27, and the control component 6 corresponds to the filter plate 31 one by one.
[0056] Reference Figure 4 and Figure 6 The control assembly 6 includes a return spring 61, a lever 62 and a pull rope 63. The lever 62 is slidably arranged on the side of the vertical plate 27 facing the filter plate 31. The lever 62 slides in the vertical direction. The top wall of the filter plate 31 is provided with a groove 311 for the corresponding lever 62 to extend into. One end of the pull rope 63 is connected to the lever 62, and the other end passes through the vertical plate 27 and is bent upward to connect to the bottom wall of the baffle 26. The collection box 2 is provided with a mounting groove at each pouring port 25. The mounting groove is arranged one-to-one with the baffle 26, and the notch of the mounting groove is opposite to the top wall of the corresponding baffle 26. The top end of the return spring 61 is fixed to the bottom of the mounting groove, and the bottom end of the return spring 61 is on the top wall of the baffle 26. The return spring 61 is used to pull the baffle 26 to cover the corresponding pouring port 25.
[0057] When two adjacent filter plates 31 are close to each other, the filter plates 31 push the lever 62 upward through the groove 311, and the lever 62 pulls the pull rope 63 upward, so that the pull rope 63 drives the baffle 26 downward and stretches the return spring 61. After the baffle 26 moves downward, the dirt can enter the corresponding storage chamber 22 through the dumping port 25. When the two adjacent filter plates 31 move away from each other, the filter plates 31 move away from the lever 62, and the return spring 61 pulls the baffle 26 upward to cover the dumping port 25, which reduces the possibility of dirt flowing into the accommodating chamber through the dumping port 25 without being filtered step by step, which is beneficial to the classification and collection of dirt, and is beneficial to the subsequent treatment of the dirt in the collection box 2 by the staff.
[0058] Reference Figure 2 and Figure 7, a prompt spring 122 is arranged in the storage groove 12, and a control switch 126 is also arranged in the storage groove 12. A prompt light 127 for power on is installed on the top of the side wall of the rainwater well 1, and the prompt light 127 is electrically connected to the control switch 126. A slide bar 123 is fixed in the storage groove 12, and the slide bar 123 is arranged vertically. The prompt spring 122 is sleeved on the slide bar 123, and a limit ring 124 is coaxially slidably sleeved on the slide bar 123. The top of the prompt spring 122 abuts against the bottom wall of the limit ring 124, and the bottom of the prompt spring 122 abuts against the bottom of the storage groove 12. A retaining ring 125 is fixedly sleeved on the top of the slide bar 123, and a clearance hole 28 for the retaining ring 125 to extend into is opened on the bottom wall of the collection box 2. The outer diameter of the limit ring 124 is larger than the aperture of the clearance hole 28, so that the top wall of the limit ring 124 can support the collection box 2. When the limiting ring 124 abuts against the blocking ring 125 , it indicates that the spring 122 is in a compressed state.
[0059] The retaining ring 125 forms an upward limiting effect on the limiting ring 124, and the limiting ring 124 keeps the prompt spring 122 on the slide bar 123 in a compressed state. When there is no dirt in the collecting box 2, the elastic force provided by the prompt spring 122 is greater than the gravity of the collecting box 2, and the prompt spring 122 presses the limiting ring 124 against the retaining ring 125. When the dirt collected in the collecting box 2 is equal to the elastic force of the prompt spring 122, the limiting ring 124 begins to compress the prompt spring 122. At this time, the collecting box 2 continues to collect dirt while the collecting box 2 moves downward and the limiting ring 124 further compresses the prompt spring 122. The collecting box 2 compresses the prompt spring 122 and presses the control switch 126 at the same time, so that the height of the collecting box 2 is kept unchanged from the time when there is no dirt in the collecting box 2 to the time when the collecting box 2 is about to be full of dirt, so as to keep the height of the pouring port 25 unchanged. After pressing the control switch 126, the control switch 126 turns on the prompt light 127, so as to promptly remind the staff that the collection box 2 needs to be replaced, which helps to reduce the possibility of clogging the rainwater well 1 due to failure to replace the collection box 2 in time after it is full of dirt.
[0060] The implementation principle of the sewage interception rainwater outlet of the embodiment of the present application is as follows: when it rains, the rainwater grate 11 intercepts solid waste with a larger volume, and the water flow drives the waste to pass through the rainwater grate 11 and flow into the rainwater well 1. The filter plate 31 filters the waste brought into the rainwater well 1 by the water flow step by step, and the filtered waste accumulates on the filter plate 31;
[0061] The water storage bucket 53 receives rainwater. As the amount of rainwater in the water storage bucket 53 increases, the water storage bucket 53 and the moving frame 52 move downward, and the filter plates 31 move upward under the action of the scissor arms 54, and two adjacent filter plates 31 move closer to each other. The cleaning and scraping assembly 4 abuts against one side of the filter plate 31 to push the dirt toward the dumping port 25. After the water storage bucket 53 moves downward until the shifting block 531 abuts against the trigger rod 55, the trigger rod 55 pushes the shifting block 531 to turn the water storage bucket 53 over, so that the water storage bucket 53 pours out the received rainwater.
[0062] The guide groove 13 can guide the water poured from the water storage bucket 53 into the guide hole 131, and the guide hole 131 diverts the water flow in the guide groove 13 to the corresponding filter plate 31, so as to flush the filter plate 31 and the cleaning brush 42;
[0063] Under the action of gravity of the filter plate 31 and the push of the spring sheet 41, the filter plates 31 move away from the fixed frame 51, and the two adjacent filter plates 31 move away from each other. At the same time, under the action of the scissor arms 54, the movable frame 52 drives the water storage bucket 53 upward, and the water storage bucket 53 returns to the normal position under the action of gravity and starts to receive rainwater again, so as to intermittently clean the dirt accumulated on the filter plates 31 while draining the rainwater well 1.
[0064] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
