Description

Technical Field

[0001] This application relates to the field of resource recycling, and particularly to a rainwater recycling device for building construction that is easy to clean. Background Art

[0002] Water resources refer to the water on the earth that has a certain quantity and available quality, can be replenished from nature and can be utilized. Water resources are widely used in human production and life, not only widely used in agriculture, industry and life, but also in aspects such as power generation, water transportation, aquaculture and environmental transformation. With the continuous advancement of urbanization, problems such as urban water shortage, water environment deterioration, ecological environment damage and urban rainstorm floods are becoming increasingly prominent. With the gradual enhancement of people's environmental protection awareness, people are paying more and more attention to the resource recycling of rainwater and wastewater. When building construction is carried out, if it may rain during the construction period, a building roof rain shield structure is usually erected. The building roof rain shield structure usually has an inclined roof, and rainwater or building sewage will flow along the roof to other places.

[0003] In the related art, a rainwater recycling device for building construction includes an inclined installation plate. A wavy water guide plate is connected to the top surface of the installation plate. The water guide plate is inclined along the inclination trend of the installation plate. The water guide plate includes a plurality of arc-shaped protrusions. A plurality of arc-shaped grooves are formed on the water guide plate. A filter plate is fixedly connected to the lowest end of each arc-shaped groove. A water discharge channel is provided at the bottom of the water guide plate. The water discharge channel is inclined. A pouring channel is connected to the lowest end of the water discharge channel. The pouring channel is inclined. The inclination degree of the pouring channel is greater than that of the water discharge channel. A water collecting bucket is provided at the lowest part of the pouring channel. Rainwater flows from the water guide plate through the filter plate and then enters the water discharge channel. Impurities remain on the filter plate and the water guide plate. The filtered rainwater enters the water discharge channel and then flows into the water collecting bucket through the pouring channel.

[0004] Regarding the above related art, the inventor believes that it is difficult to clean the impurities on the filter plate because the filter plate is fixedly connected to the bottom of the arc-shaped groove. The filter plate is prone to blockage after long-term filtering of impurities, and the drainage effect will be affected after the filter plate is blocked. Summary of the Invention

[0005] In order to reduce the possibility of blockage of the filter plate, this application provides a rainwater recycling device for building construction that is easy to clean.

[0006] A rainwater recycling device for building construction that is easy to clean provided by this application adopts the following technical solutions:

[0007] A rainwater recycling device for building construction that is convenient for cleaning, comprising an inclined mounting plate. A wavy water guide plate is arranged on the top surface of the mounting plate. The water guide plate includes a plurality of arc-shaped protrusions, and a plurality of arc-shaped grooves are formed on the water guide plate. A filter plate is connected to the lowest end of each arc-shaped groove. A water discharge channel is arranged at the bottom of the water guide plate, and the water discharge channel is inclined. The lowest end of the water discharge channel is connected to a water pouring channel, and the water pouring channel is inclined. The inclination degree of the water pouring channel is greater than that of the water discharge channel. A water collecting bucket is arranged at the lowest part of the water pouring channel. The filter plate is rotatably arranged. A filter frame is arranged in the water discharge channel, and the filter frame is located below the filter plate. The filter plate can be rotated into the filter frame, and the filter plate can also be rotated back to its original position.

[0008] By adopting the above technical solution, after the filter plate is rotated into the filter frame, the accumulated impurities fall from the filter plate into the filter frame, reducing the accumulation of impurities on the filter plate. Rainwater can still flow through the filter frame and then enter the water discharge channel, reducing the possibility of the filter plate being blocked and the impact on the drainage effect.

[0009] Optionally, a spare filter plate is arranged at the lowest part of each arc-shaped protrusion. The spare filter plate is rotatably arranged. One end of the spare filter plate close to the adjacent filter plate is the rotation axis of the spare filter plate. The spare filter plate can be rotated to the position before the filter plate rotates, and the spare filter plate can also be rotated back to its original position.

[0010] By adopting the above technical solution, when the filter plate rotates downward into the water discharge channel, the spare filter plate rotates to the position before the filter plate rotates, reducing the possibility that impurities directly enter the water discharge channel from the water guide plate when the filter plate is in the cleaning process.

[0011] Optionally, a rotating mechanism is arranged at the lowest part of the water guide plate. The rotating mechanism includes a rotating motor, a synchronous rod, and a linkage assembly. The length direction of the synchronous rod is arranged along the arrangement direction of the filter plates. The rotating shaft of the rotating motor is connected to one end of the synchronous rod. The synchronous rod is located on the side of the filter plate close to the bottom wall of the water guide plate, and the synchronous rod is connected to the bottom surface of each filter plate. The linkage assembly is located between the filter plate and the spare filter plate, and the linkage assembly drives the spare filter plate to rotate towards the position before the filter plate rotates.

[0012] By adopting the above technical solution, the rotating motor drives the synchronous rod to rotate, and the synchronous rod drives each filter plate to rotate downward synchronously, realizing the rotation of the filter plate and also enabling each filter plate to rotate synchronously, improving the efficiency.

[0013] Optionally, the linkage assembly includes a gear set and a rotating rod. The gear set includes a first gear, a second gear, a synchronous belt, a first bevel gear, and a second bevel gear. The first gear is connected to the synchronous rod and coaxially arranged. The synchronous belt meshes with both the first gear and the second gear. The first bevel gear and the second gear are coaxially arranged. The second bevel gear meshes with the first bevel gear. The rotating rod is connected to the second bevel gear and coaxially arranged. The rotating rod is the rotating shaft of the spare filter plate.

[0014] By adopting the above technical solution, when the rotating motor drives the synchronous rod to rotate and drives the filter plate to rotate downward by 180 degrees, the synchronous rod drives the first gear to rotate synchronously. The second gear rotates in the same direction as the first gear through the synchronous belt, driving the first bevel gear and the synchronous rod to rotate in the same direction, driving the second bevel gear to rotate in the direction before the filter plate rotates, driving the spare filter plate to rotate 180 degrees in the direction before the filter plate rotates until it is located at the position before the filter plate rotates, realizing that the filter plate rotates downward while driving the spare filter plate to rotate in the direction before the filter plate rotates. This not only improves the synchronization of the rotation of the filter plate and the spare filter plate, but also further reduces the possibility that impurities directly enter the water outlet channel from the water guide plate when the filter plate is in the cleaning process; it also uses one driving source to drive the rotation of the filter plate and the spare filter plate at the same time, saving energy.

[0015] Optionally, a cleaning assembly is provided on the filter frame. The cleaning assembly includes a cleaning box. The cleaning box is slidably arranged on the bottom wall of the filter frame. The cleaning box can slide to contact the filter plate and can also slide away from the filter plate. The cleaning box includes a box body and a cover body. The cover body is rotatably arranged. A cleaning brush is arranged to move up and down in the box body. A connecting rope is connected to the cleaning brush. The cleaning brush and the cover body are connected by the connecting rope. One end of the connecting rope is connected to the end of the cover body close to the filter plate. One end of the cleaning brush away from the connecting rope is connected to a telescopic rod. The end of the telescopic rod away from the cleaning brush is connected to the inner wall of the bottom of the box body. The telescopic rod includes a cylinder body and a rod body. The rod body slides in the cylinder body. The cylinder body is connected to the inner wall of the bottom of the box body. A limiting plate is connected to the top surface of the rod body. The top surface of the limiting plate is connected to the cleaning brush. The other end of the connecting rope is connected to the limiting plate.

[0016] By adopting the above technical solution, when the filter plate rotates into the filter frame, the cleaning box slides to contact the filter plate, driving the cover body to rotate to open. When the cover body opens, it drives the cleaning brush to rise through the connecting rope. The telescopic rod is used to limit the cleaning brush to move up and down along the straight line in the length direction of the telescopic rod. When the cleaning brush rises, the bristles of the cleaning brush clean the surface of the filter plate, further reducing the possibility of the filter plate being blocked.

[0017] Optionally, a first relief through groove is formed in the inner wall of the filtering frame close to the filtering plate, and a second relief through groove is formed in the inner wall of the water outlet channel close to the filtering plate. A sliding rod is slidably arranged in the first relief through groove. The sliding rod can slide from the first relief through groove to the second relief through groove, and can also slide from the second relief through groove to the first relief through groove. One end of the sliding rod away from the bottom wall of the first relief through groove contacts the filtering plate, and the filtering plate pushes the sliding rod to slide towards the water guide plate; A connecting rod is connected to one end of the sliding rod away from the cleaning box, and one end of the connecting rod away from the sliding rod is connected to the cleaning box. A first spring is connected to one side of the cleaning box away from the sliding rod, and one end of the first spring away from the cleaning box is connected to the inner wall of the filtering frame.

[0018] By adopting the above technical solution, when the filtering plate rotates into the filtering frame and contacts the sliding rod, it pushes the sliding rod to slide towards the water guide plate. The sliding plate drives the cleaning box to slide towards the filtering plate through the connecting rod, realizing the sliding of the cleaning box. At this time, the first spring is stretched. When the filtering plate rotates back to its original position, the first spring drives the cleaning box to automatically return to its original position, and at the same time drives the sliding rod to automatically return to its original position; Utilize the rotation of the filtering plate and the elasticity of the first spring to drive the sliding of the cleaning box, further saving energy.

[0019] Optionally, the cover body is rotationally connected to the box body through a torsion spring. The torsion spring is in a tensioned state when the cleaning box is closed. The rotation axis of the cover body is away from the filtering plate, and the cleaning box opens when the cover body rotates towards the direction away from the filtering plate;

[0020] A locking component is arranged on the cleaning box. The locking component includes a locking block and a locking plate. The locking block is located on the box body, and the locking plate is located on the cover body. The locking block and the locking plate are used in cooperation; A connecting rod is connected to the locking block. The connecting rod is arranged in a "U" shape. A locking through groove is formed in the inner wall of the box body. One end of the connecting rod away from the locking block passes through the locking through groove and contacts the filtering plate;

[0021] The locking block is arranged in a wedge shape. The wedge surface of the locking block is on the side close to the filtering plate. A relief hole is formed in the locking plate. The locking plate is closer to the filtering plate than the locking block. The locking plate is also arranged in a wedge shape. The wedge surface of the locking block is adapted to the wedge surface of the locking plate, and the locking block passes through the relief hole;

[0022] A sliding block is connected to the circumferential side wall of the connecting rod. A sliding groove is formed in the bottom wall of the locking through groove. The sliding block slides in the sliding groove. A second spring is connected to the surface of the sliding block away from the locking block, and one end of the second spring away from the locking block is connected to the inner wall of the sliding groove.

[0023] By adopting the above technical solution, when the cleaning box slides to the point where the connecting rod and the filter plate are in contact, the connecting rod slides in a direction away from the filter plate, causing the locking block and the clearance hole to disengage; since the torsion spring is in a tensioned state when the cleaning box is closed, after the locking block and the clearance hole are disengaged, the cover body automatically rotates in a direction away from the filter plate under the action of the torsion spring, causing the cleaning box to open automatically, thereby improving the automation of opening the cleaning box; when the filter plate returns to its original position, the cleaning box slides in a direction away from the filter plate under the action of the first spring, causing the connecting rod and the filter plate to disengage, and the connecting rod slides to its original position in a direction close to the filter plate under the action of the second spring.

[0024] When the cleaning box returns to its original position, the staff rotates the cover until the locking block passes through the clearance hole, so that the cleaning box is closed.

[0025] Optionally, a push rod is provided on a side of the filter frame away from the filter plate, and one end of the push rod away from the side wall of the filter frame is in contact with the top surface of the cover body.

[0026] By adopting the above technical solution, when the cleaning box slides to its original position, the push rod contacts the top surface of the cover body, pushing the cover body back to its original position automatically. At this time, the locking block and the clearance hole are used in conjunction so that the locking block passes through the clearance hole, thereby realizing automatic closing of the cleaning box and improving the automation of closing the cleaning box.

[0027] Optionally, a baffle is rotatably provided on the guide plate, and the baffle can be rotated to contact with a side of the filter plate close to the sewer channel, and the baffle can also be rotated to be separated from the filter plate.

[0028] By adopting the above technical solution, when the filter plate does not need to be cleaned, the baffle is rotated until it contacts the side of the filter plate close to the sewer channel to provide support for the filter plate, thereby reducing the possibility of the filter plate being separated from the water guide plate due to the impact of water flow or the accumulation of impurities, and improving the stability of the filter plate on the water guide plate; when the filter plate needs to be cleaned, the baffle is rotated until it is separated from the filter plate.

[0029] Optionally, the filter frame and the sewer channel are detachably connected, and lap plates are connected to both sides of the filter frame, and the lap plates are mounted on the top surface of the side wall of the sewer channel.

[0030] By adopting the above technical solution, the filter frame can be installed on the sewer channel by bridging the lap plate on the side wall of the sewer channel, the lap plate is lifted, the filter frame is removed from the sewer channel, and the cleaning box is opened to facilitate pouring out impurities in the filter frame and the cleaning box.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. After the filter plate rotates into the filter box, the accumulated impurities fall from the filter plate into the filter box, reducing the accumulation of impurities on the filter plate. Rainwater can still flow through the filter box and enter the drainage channel, reducing the possibility of the filter plate being blocked and the impact on the drainage effect;

[0033] 2. When the filter plate rotates downward into the drainage channel, the spare filter plate rotates to the position where the filter plate was before rotation, reducing the possibility that impurities directly enter the drainage channel from the water guide plate when the filter plate is being cleaned;

[0034] 3. When the filter plate rotates into the filter box, the cleaning box slides to contact the filter plate, driving the cover to rotate to open. When the cover opens, the cleaning brush is driven to rise by the connecting rope. The telescopic rod is used to limit the up and down movement of the cleaning brush along the straight line in the length direction of the telescopic rod. When the cleaning brush rises, the bristles of the cleaning brush clean the surface of the filter plate, further reducing the possibility of the filter plate being blocked.

Detailed implementation manners

[0046] The following further elaborates on this application in conjunction with the attached Figures 1 - 10 drawings.

[0047] An embodiment of this application discloses a rainwater recycling device for building construction that is easy to clean. Refer to Figure 1 and Figure 2 , the rainwater recycling device for building construction that is easy to clean includes a mounting plate 1, the mounting plate 1 is inclined, a wavy water guide plate 2 is fixedly installed on the top surface of the mounting plate 1, the water guide plate 2 includes a plurality of arc-shaped protrusions 21, a plurality of arc-shaped grooves 22 are formed on the water guide plate 2, the arc-shaped protrusions 21 and the arc-shaped grooves 22 are arranged adjacent to each other, the arc-shaped protrusions 21 are located on the right side of the arc-shaped grooves 22, and in this embodiment, the number of the arc-shaped protrusions 21 and the arc-shaped grooves 22 is three; a semi-circular filter plate 3 is connected to the lowest end of each arc-shaped groove 22, and the filter plates 3 are all rotatably arranged; the lowest part at the bottom of the water guide plate 2 is connected to a water discharge channel 4, the water discharge channel 4 is inclined, the length direction of the water discharge channel 4 is arranged along the arrangement direction of the filter plates 3, the lowest part of the water discharge channel 4 is connected to an inclined water pouring channel 41, the inclination degree of the water pouring channel 41 is greater than that of the water discharge channel 4, and a water collecting bucket 5 is placed at the lowest part of the water pouring channel 41.

[0048] Refer to Figure 1 , Figure 2 and Figure 3, a filter frame 42 is detachably installed in the water drainage channel 4. The filter frame 42 is located below the filter plate 3. One end of the filter frame 42 is close to the highest end of the water drainage channel 4, and the other end of the filter frame 42 is close to the lowest end of the water drainage channel 4. The width of the filter frame 42 is smaller than the radius of the opening of the water drainage channel 4. The filter plate 3 can be rotated into the filter frame 42, and the filter plate 3 can also be rotated back to its original position. A lapping plate 421 is fixedly connected to the top surface of the side of the filter frame 42 away from the filter plate 3. The lapping plate 421 is lapped on the top surface of the side of the water drainage channel 4 away from the filter plate 3, so as to realize the detachable installation of the filter frame 42 in the water drainage channel 4. Lapping the lapping plate 421 on the side wall of the water drainage channel 4 can install the filter frame 42 on the water drainage channel 4. Lift the lapping plate 421, then remove the filter frame 42 from the water drainage channel 4, and then open the cleaning box 71 to facilitate pouring out the impurities in the filter frame 42 and the cleaning box 71. Baffles 221 are rotatably installed on the outer walls at both ends of each arc-shaped groove 22. The side of the baffle 221 close to the water guide plate 2 contacts the side of the filter plate 3 away from the water guide plate 2. Rotate the baffle 221 to contact the side of the filter plate 3 close to the water drainage channel 4 to provide support for the filter plate 3, reducing the possibility of the filter plate 3 detaching from the water guide plate 2 due to the impact of water flow or the accumulation of impurities, and improving the stability of the filter plate 3 on the water guide plate 2.

[0049] Rainwater flows from the water guide plate 2 through the filter plate 3 and then enters the water drainage channel (4). The impurities remain on the filter plate 3 and the water guide plate 2. The filtered rainwater flows through the filter holes, enters the water drainage channel 4, and then enters the water collecting bucket 5. After the filter plate 3 is rotated into the filter frame 42, the accumulated impurities fall from the filter plate 3 into the filter frame 42, reducing the accumulation of impurities on the filter plate 3. The rainwater can still flow through the filter frame 42, thus reducing the possibility of the filter plate 3 being blocked, and further reducing the impact on the drainage effect.

[0050] Refer to Figure 1 and Figure 3 , a spare filter plate 31 is rotatably connected to the lowest point of each arc-shaped protrusion 21. One end of the spare filter plate 31 close to the adjacent filter plate 3 is the rotating shaft of the spare filter plate 31. The spare filter plate 31 can be rotated to the position before the filter plate 3 rotates, and the spare filter plate 31 can also be rotated back to its original position. When the filter plate 3 rotates downward into the water drainage channel 4, the spare filter plate 31 rotates to the position before the filter plate 3 rotates, reducing the possibility that impurities directly enter the water drainage channel 4 from the water guide plate 2 when the filter plate 3 is in the cleaning process.

[0051] Refer to Figure 1 and Figure 4, a rotating mechanism 6 is installed at the lowest part of the water guide plate 2. The rotating mechanism 6 includes a rotating motor 61, a synchronous rod 62 and a linkage assembly 63. The length direction of the synchronous rod 62 is arranged along the arrangement direction of the filter plates 3. The rotating motor 61 is installed on the left side of the water guide plate 2. The rotating shaft of the rotating motor 61 is connected to one end of the synchronous rod 62. The synchronous rod 62 is located on the side of the filter plates 3 close to the bottom wall of the water guide plate 2. The synchronous rod 62 is connected to the bottom surface of each filter plate 3. Each filter plate 3 rotates downward by 180 degrees along the circumferential direction of the synchronous rod 62 at the same time. The rotating motor 61 drives the synchronous rod 62 to rotate, and the synchronous rod 62 drives each filter plate 3 to rotate downward synchronously, realizing the rotation of the filter plates 3 and also making each filter plate 3 rotate synchronously, improving the efficiency; the linkage assembly 63 is located between the filter plates 3 and the spare filter plates 31. One spare filter plate 31 corresponds to one set of linkage assemblies 63. The linkage assembly 63 drives the spare filter plate 31 to rotate towards the position before the rotation of the filter plate 3 until it is located at the position before the rotation of the filter plate 3.

[0052] Refer to Figure 1 and Figure 4 , the linkage assembly 63 includes a gear set 631 and a rotating rod 632. The gear set 631 includes a first gear 6311, a second gear 6312, a synchronous belt 6313, a first bevel gear 6314 and a second bevel gear 6315. The first gear 6311 is fixedly connected to the synchronous rod 62 and coaxially arranged. The synchronous belt 6313 meshes with both the first gear 6311 and the second gear 6312. A support rod 6316 is fixedly connected to the second gear 6312. The support rod 6316 is also fixedly connected to the first bevel gear 6314. The support rod 6316, the second gear 6312 and the first bevel gear 6314 are all coaxially arranged. The second bevel gear 6315 meshes with the first bevel gear 6314. The rotating rod 632 is fixedly connected to the second bevel gear 6315 and coaxially arranged. The rotating rod 632 is the rotating shaft of the spare filter plate 31.

[0053] When the rotating motor 61 drives the synchronous rod 62 to rotate and drives the filter plate 3 to rotate downward by 180 degrees, the synchronous rod 62 drives the first gear 6311 to rotate synchronously. The second gear 6312 rotates in the same direction as the first gear 6311 through the synchronous belt 6313, driving the first bevel gear 6314 to rotate in the same direction as the synchronous rod 62, driving the second bevel gear 6315 to rotate towards the direction before the rotation of the filter plate 3, driving the spare filter plate 31 to rotate towards the direction before the rotation of the filter plate 3 by 180 degrees until it is located at the position before the rotation of the filter plate 3, realizing that while the filter plate 3 rotates downward, it drives the spare filter plate 31 to rotate towards the direction before the rotation of the filter plate 3. This not only improves the synchronization of the rotation of the filter plate 3 and the spare filter plate 31, further reducing the possibility that impurities directly enter the water discharge channel 4 from the water guide plate 2 when the filter plate 3 is in the cleaning process; but also uses one driving source to drive the rotation of the filter plate 3 and the spare filter plate 31 at the same time, saving energy.

[0054] Refer to Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , a cleaning component 7 is installed on the filtering frame 42. The cleaning component 7 includes a cleaning box 71 which is installed on the filtering frame 42. The cleaning box 71 is slidably arranged on the bottom wall of the filtering frame 42. The cleaning box 71 can slide to contact the filter plate 3 and can also slide away from the filter plate 3. A dovetail block 711 is fixedly connected to the bottom surface of the cleaning box 71. A dovetail groove 712 is correspondingly formed on the top surface of the filtering frame 42. The dovetail block 711 slides in the dovetail groove 712. The cooperation of the dovetail block 711 and the dovetail groove 712 reduces the possibility of the cleaning box 71 falling off the filtering frame 42 due to inclination.

[0055] Refer to Figure 5 and Figure 6 As shown in Figure 5 and Figure 6 , the cleaning box 71 includes a box body 713 and a cover body 714. The cover body 714 is rotatably connected to the top of the box body 713 through a torsion spring. The rotation axis of the cover body 714 is away from the filter plate 3. When the cover body 714 rotates in the direction away from the filter plate 3, the cleaning box 71 is opened. When the cleaning box 71 is opened, the torsion spring is in a relaxed state. When the cleaning box 71 is closed, the torsion spring is in a tensioned state. A cleaning brush 72 is installed in the box body 713. The cleaning brush 72 is arranged to move up and down. The bristles of the cleaning brush 72 are elastic. A connecting rope 73 is fixedly connected to the cleaning brush 72. The cleaning brush 72 and the cover body 714 are connected through the connecting rope 73. One end of the cleaning brush 72 away from the connecting rope 73 is fixedly connected to a telescopic rod 74. The end of the telescopic rod 74 away from the cleaning brush 72 is fixedly connected to the bottom wall of the box body 713. The telescopic rod 74 includes a rod body 741 and a cylinder body 742. The bottom surface of the cylinder body 742 is fixedly connected to the inner wall of the bottom wall of the box body 713. The rod body 741 slides in the cylinder body 742. A limiting plate 743 is fixedly connected to the top surface of the rod body 741. The top surface of the limiting plate 743 is fixedly connected to the cleaning brush 72 to reduce the possibility of the rod body 741 sliding out of the cylinder body 742. One end of the connecting rope 73 is fixedly connected to one end of the cover body 714 close to the filter plate 3, and the other end of the connecting rope 73 is fixedly connected to the limiting plate 743. When the cover body 714 rotates 90 degrees in the direction away from the filter plate 3, the connecting rope 73 is straightened. In this embodiment, there are two connecting ropes 73, cleaning brushes 72, telescopic rods 74 and limiting plates 743 corresponding to each cleaning box 71.

[0056] After the filter plate 3 rotates into the filter frame 42, the cleaning box 71 slides to contact the filter plate 3, and the driving cover 714 rotates to open. When the cover 714 opens, the cleaning brush 72 is driven to rise by the connecting rope 73. The telescopic rod 74 is used to limit the up and down movement of the cleaning brush 72 along the straight line in the length direction of the telescopic rod 74. When the cleaning brush 72 rises, when the bristles of the cleaning brush 72 rise out of the cleaning box 71, at this time, the bristles of the cleaning brush 72 elastically extend out of the cleaning box 71 to clean the surface of the filter plate 3, further reducing the possibility of blockage of the filter plate 3; when the cover 714 is closed, the cleaning brush 72 automatically descends under the action of gravity. At this time, the bristles of the cleaning brush 72 are elastically bent and fit against the inner wall of the cleaning box 71 to realize the storage of the cleaning brush 72.

[0057] Referring to Figure 7 , a first relief through groove 8 is opened on the inner wall of the filter frame 42 close to the filter plate 3, and a second relief through groove 81 is opened on the inner wall of the water outlet channel 4 close to the filter plate 3. A sliding rod 82 is installed in the first relief through groove 8. The sliding rod 82 can slide from the first relief through groove 8 to the second relief through groove 81, and the sliding rod 82 can also slide from the second relief through groove 81 to the first relief through groove 8. The surface of the sliding rod 82 close to the filter plate 3 is a wedge surface. One end of the sliding rod 82 far from the filter plate 3 is fixedly connected with a connecting rod 83. The connecting rod 83 is in a "U" shape. The connecting rod 83 first passes through the first relief through groove 8 and the second relief through groove 81 in sequence and then bends downward, then bends to the left, and then passes through the second relief through groove 81 and the first relief through groove 8 in sequence and is fixedly connected with the surface of the bottom of the cleaning box 71 close to the filter plate 3. One end of the sliding rod 82 far from the first relief through groove 8 contacts the filter plate 3, and the filter plate 3 pushes the sliding rod 82 to slide in the direction close to the water guide plate 2; a first spring 84 is fixedly connected to the side of the cleaning box 71 far from the sliding rod 82, and one end of the first spring 84 far from the cleaning box 71 is fixedly connected with the inner wall of the filter frame 42.

[0058] When the filter plate 3 rotates into the filter frame 42 and contacts the sliding rod 82, it pushes the sliding rod 82 to slide in the direction close to the water guide plate 2. The sliding plate drives the cleaning box 71 to slide in the direction close to the filter plate 3 through the connecting rod 83, realizing the sliding of the cleaning box 71. Set the radius of the filter plate 3, the height of the cleaning box 71, the length of the sliding rod 82, and the distance between the sliding rod 82 and the synchronous rod 62 according to the actual situation, so that the filter plate 3 pushes the sliding rod 82 after rotating 90 degrees. At this time, the first spring 84 is stretched; when the filter plate 3 rotates to its original position, it pushes the cleaning box 71 to slide in the direction away from the filter plate 3. The first spring 84 drives the cleaning box 71 to automatically return to its original position while returning to its original shape, and at the same time drives the sliding rod 82 to automatically return to its original position; using the rotation of the filter plate 3 and the elasticity of the first spring 84 to drive the sliding of the cleaning box 71 further saves energy.

[0059] Reference Figure 7 、 Figure 8 and Figure 9 A locking assembly 9 is installed on the cleaning box 71. The locking assembly 9 includes a locking block 91 and a locking plate 92. The locking block 91 is located on the box body 713, and the locking plate 92 is located on the cover body 714. The locking block 91 and the locking plate 92 are used in cooperation. A connecting rod 911 is fixedly connected to the surface of the locking block 91 away from the filter plate 3. The connecting rod 911 is in a "U" shape and the opening of the "U" shape faces the filter plate 3. A locking through groove 912 is formed on the inner wall of the box body 713. One end of the connecting rod 911 away from the locking block 91 passes through the locking through groove 912 and contacts the filter plate 3. The locking block 91 is wedge-shaped, and the wedge surface of the locking block 91 is on the side close to the filter plate 3. A relief hole is formed on the locking plate 92. The locking plate is closer to the filter plate than the locking block. The locking plate is also wedge-shaped. The wedge surface of the locking block 91 is adapted to the wedge surface of the locking plate 92. The wedge surface of the locking block 91 is on the side close to the filter plate 3. The locking plate 92 is fixedly connected to the bottom surface of the cover body 714 on the side close to the filter plate 3. A relief hole 921 is formed on the locking plate 92. The locking plate 92 is closer to the filter plate 3 than the locking block 91. The bottom surface of the locking plate 92 is wedge-shaped. The locking plate 92 and the locking block 91 are used in cooperation. When the cover body 714 is closed with the box body 713, the locking block 91 passes through the relief hole 921.

[0060] Reference Figure 8 and Figure 10 A slider 913 is fixedly connected to the bottom surface of the connecting rod 911. A sliding groove 914 is correspondingly formed on the inner wall of the locking through groove 912. The slider 913 slides in the sliding groove 914. A second spring 915 is fixedly connected to the surface of the slider 913 away from the locking block 91. One end of the second spring 915 away from the locking block 91 is fixedly connected to the inner wall of the sliding groove 914. A push rod 93 is fixedly connected to the side of the filter frame 42 away from the filter plate 3. One push rod 93 corresponds to one cleaning box 71. One end of the push rod 93 away from the side wall of the filter frame 42 contacts the top surface of the cover body 714.

[0061] When the cleaning box 71 slides to the point where the connecting rod 911 and the filter plate 3 are in contact, the connecting rod 911 slides in the direction away from the water guide plate 2, causing the locking block 91 and the clearance hole 921 to disengage. Since the torsion spring is in a tensioned state when the cleaning box 71 is closed, after the locking block 91 and the clearance hole 921 are disengaged, the cover body 714 automatically rotates in the direction away from the filter plate 3 under the action of the torsion spring, allowing the cleaning box 71 to be automatically opened, thereby improving the automation of opening the cleaning box 71. At this time, the second spring 915 is stretched; when the filter plate 3 returns to its original position, the cleaning box 71 slides in the direction away from the filter plate 3 under the action of the first spring 84, causing the connecting rod 911 and the filter plate 3 to disengage, and the connecting rod 911 slides to its original position in the direction close to the filter plate 3 under the action of the second spring 915. When the cleaning box 71 slides to its original position, the push rod 93 contacts the top surface of the cover body 714, pushing the cover body 714 back to its original position automatically. At this time, the locking block 91 and the clearance hole 921 are used in conjunction with each other so that the locking block 91 passes through the clearance hole 921, realizing the automatic closing of the cleaning box 71 and improving the automation of the closing of the cleaning box 71.

[0062] The implementation principle of the rainwater recycling equipment for house construction that is easy to clean in the embodiment of the present application is as follows: first, the baffle plate 221 is rotated to be separated from the filter plate 3, and then the rotating motor 61 is started to drive the filter plate 3 to rotate 180 degrees toward the sewer channel 4, and at the same time, the spare filter plate 31 rotates toward the position before the filter plate 3 rotates; when the filter plate 3 rotates to contact the sliding plate, the sliding rod 82 is pushed to slide in the direction close to the water guide plate 2, driving the cleaning box 71 to slide toward the filter plate 3, and when the filter plate 3 and the cleaning box 71 are in contact, the filter plate 3 pushes the connecting rod 911 to slide in the direction away from the water guide plate 2, so that the locking block 91 and the giving hole 921 are separated, and because the torsion spring is in a tensioned state when the cleaning box 71 is closed, after the locking block 91 and the giving hole 921 are separated, the cover body 714 automatically rotates in the direction away from the filter plate 3 under the action of the torsion spring, so that the cleaning box 71 can be automatically opened, and the cover body 714 drives the cleaning brush 72 to rise through the connecting rope 73, and the cleaning brush 72 rises to clean the surface of the filter plate 3.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
