[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] First, according to the present invention, when rainwater enters the water inlet pipe through the water trough, the rainwater spirally flows downward through the spiral plate and then impacts the side wall of the driving blade, so that the driving blade drives the driving shaft, the driven shaft, the multi-link and the weight block to rotate together. The multi-link will expand outward by a corresponding distance due to the rotation speed. The weight block drives the inner shaft and the extrusion rod to move together with the expansion of the multi-link. The extrusion rod therefore pushes the transmission rod along the inner wall of the transmission groove, and the linkage frame and the filter rotate together, so that the position of the filter inside the water inlet pipe changes, and the pores on the filter gradually increase in the counterclockwise direction. When the rotation speed of the multi-link is higher, the distance the weight block moves upward is greater, and the rotation angle of the transmission rod is also greater. The part with larger pores on the filter can be inside the water inlet pipe. Therefore, the speed of filtering rainwater can be adjusted according to the size of the rain. The existing problem that the drainage work cannot be completed smoothly is solved.

[0018] Secondly, the present invention, by fixing the linkage disk installed on the top of the inner shaft on the bottom wall of the pressing frame, allows the inner shaft to move up and down together with the pressing frame, and the transmission rod repeatedly rotates as the inner shaft moves up and down. When the rain is light, the part with smaller pores is located inside the water inlet pipe, thereby ensuring the filtering efficiency of rainwater.

[0019] Thirdly, the present invention, by slidingly installing a rectangular limit bar inside the inner shaft, limits the inner shaft by the limit bar, so that the inner shaft does not rotate together with the driven shaft, thereby ensuring the stability of the inner shaft and preventing the inner shaft from rotating along with the driven shaft, causing the transmission rod to drive the filter to rotate together, and preventing the position of the filter from being unstable.

[0020] Fourthly, in the present invention, when the snap-in slot is separated from the snap-in slot, the elasticity of the torsion spring will drive the mounting plate to rotate, driving the cleaning brush and the connecting frame to return to their original positions, until the convex plate slides back into the interior of the snap-in slot, driving the connecting frame to rotate, and repeatedly cleaning the surface of the filter screen with the cleaning brush to remove impurities on the surface of the filter screen, thereby ensuring the filtering effect of the filter screen.

[0021] Fifth, the present invention places a sealing plate on the top wall of the filter and fits the filter to the outer wall of the water inlet pipe to seal the part of the screen slot near the top, thereby preventing rainwater from entering the interior of the collection barrel through the screen slot. By rotating the guide plate together with the drive shaft, the guide plate can push the sliding rod and the baffle plate to move upward, so that a certain gap is generated between the sealing plate and the filter, which facilitates the rotation of the filter. When the sliding rod and the guide plate are staggered, the sealing plate falls back on the side wall of the filter, causing the filter to vibrate to a certain amplitude. Impurities on the surface of the filter slide down along the side wall of the filter due to the vibration, so that the filter can rotate while improving the impurity treatment efficiency.

A linkage frame 49 is fixedly mounted on the top of the outer side wall of the transmission rod 46, and the linkage frame 49 is fixedly mounted on the bottom of the filter screen 3. When rainwater enters the interior of the water inlet pipe 11 through the water trough 14, it will first fall on the side wall of the spiral plate 28, and the rainwater will be The spiral flows downward and then impacts the side wall of the driving blade 22, so that the driving blade 22 drives the driving shaft 21 to rotate together.

[0036] like Figure 1-Figure 8As shown, in order to ensure the stability of the inner shaft 45 when it slides up and down, a positioning assembly is provided inside the collection barrel 15, and the positioning assembly includes a positioning groove 81 opened on the top wall of the inner shaft 45, and a linkage disk 82 is rotatably installed inside the positioning groove 81.

When the rain is light, the part with smaller pores is located inside the water inlet pipe 11, ensuring the rainwater Filtration efficiency; a movable column 83 is provided at the bottom of the positioning groove 81, and the movable column 83 is fixedly installed on the inner bottom wall of the collecting barrel 15, and a limit strip 84 is fixedly installed on the top wall of the collecting barrel 15, and the limit strip 84 is rectangular in shape, and a limit slot 85 is provided inside the inner shaft 45, and the limit strip 84 is slidably installed inside the limit slot 85; by slidingly installing the rectangular limit strip 84 inside the inner shaft 45, the limit strip 84 limits the inner shaft 45, so that the inner shaft 45 will not rotate with the driven shaft 24, thereby ensuring the stability of the inner shaft 45, and avoiding the inner shaft 45 rotating with the driven shaft 24, causing the transmission rod 46 to drive the filter screen 3 to rotate together, and the position of the filter screen 3 is not stable enough.

[0037] like Figure 1-Figure 8As shown, in order to ensure the filtering effect of the filter screen 3, the side wall of the filter screen 3 is inclined, and a cleaning assembly is arranged inside the collection barrel 15, and the cleaning assembly includes a mounting plate 51 arranged on the top of the linkage frame 49, and the mounting plate 51 is rotatably mounted on the side wall of the driven shaft 24. A positioning plate 52 is arranged on the top of the mounting plate 51, and the positioning plate 52 is rotatably mounted on the side wall of the driven shaft 24 through a bearing, and one end of the mounting plate 51 away from the driven shaft 24 is fixedly mounted on the side wall of the water inlet pipe 11, and a torsion spring 53 is clamped on a side wall surface close to the mounting plate 51 and the positioning plate 52, and two connecting rods 54 are fixedly mounted on the outer wall of the mounting plate 51, and the two connecting rods 54 are fixed on the side wall. A connecting frame 56 is installed, and the connecting frame 56 is fitted with the inner wall of the filter 3. A cleaning brush 55 is fixedly installed on the side wall of the connecting frame 56, and the cleaning brush 55 is fitted with the side wall of the filter 3. A scraping assembly is arranged inside the collecting barrel 15, and the scraping assembly includes a fixing frame 61 fixedly installed on the side wall of the driven shaft 24, and a receiving groove 62 is provided on the side wall of the fixing frame 61 close to the connecting frame 56, and a sliding block 63 is slidably installed inside the receiving groove 62, and a convex plate 64 is fixedly installed on the side wall of the sliding block 63 away from the fixing frame 61, and an expansion spring 65 is fixedly connected to the side wall of the sliding block 63, and one end of the expansion spring 65 away from the sliding block 63 is installed in the receiving groove 62, the inner wall of the connecting frame 56 is provided with a clamping groove 66 aligned with the convex plate 64; by fixing the fixing frame 61 on the side wall of the driven shaft 24, the fixing frame 61 can rotate together with the driven shaft 24, and the convex plate 64 is clamped in the inside of the clamping groove 66, so that the cleaning brush 55 rotates together with the connecting frame 56, so that the cleaning brush 55 cleans the surface of the filter 3 and scrapes off the impurities on the surface of the filter 3, and the side wall of the filter 3 is inclined, and the impurities scraped by the cleaning brush 55 will slide along the side wall of the filter 3 to the inside of the collecting bucket 15, so that the collecting bucket 15 collects the impurities. Since part of the filter 3 is inside the water inlet pipe 11, The cleaning brush 55 cannot enter the interior of the water inlet pipe 11. When the cleaning brush 55 contacts the side wall of the water inlet pipe 11 and cannot continue to rotate, the convex plate 64 retracts into the interior of the accommodating groove 62 due to the influence of resistance, so that the fixing frame 61 can continue to rotate. When the clamping groove 66 is separated from the clamping groove 66, since the position of the positioning plate 52 is fixed, the elasticity of the torsion spring 53 will drive the mounting plate 51 to rotate, and drive the cleaning brush 55 and the connecting frame 56 to return to their original positions until the convex plate 64 slides into the interior of the clamping groove 66 again, driving the connecting frame 56 to rotate, and the surface of the filter screen 3 is repeatedly cleaned by the cleaning brush 55 to remove impurities on the surface of the filter screen 3 to ensure the filtering effect of the filter screen 3.

[0038] like Figure 1-Figure 8As shown, in order to prevent rainwater inside the water inlet pipe 11 from directly entering the interior of the collection barrel 15, a sealing assembly is provided inside the collection barrel 15, and the sealing assembly includes two sealing plates 71 attached to the top wall of the filter screen 3, and the side wall surface of the two sealing plates 71 adjacent to each other is attached to the outer wall of the water inlet pipe 11; by placing the sealing plates 71 on the top wall surface of the filter screen 3, and attaching the filter screen 3 to the outer wall of the water inlet pipe 11, the part close to the top of the mesh slot 17 is sealed to prevent rainwater from entering the interior of the collection barrel 15 through the mesh slot 17; baffles 75 are fixedly installed on the top walls of the two sealing plates 71, and sliding rods 74 are fixedly installed on the side walls adjacent to the two baffles 75; the inner side wall of the water inlet pipe 11 is provided with a movable groove 76 aligned with the sliding rod 74, and the side wall surface adjacent to the two sliding rods 74 is attached to the side wall of the drive shaft 21. The bottom wall of the driving shaft 21 is fixedly installed with a supporting bottom plate 72, and the top wall of the supporting bottom plate 72 is fixedly installed with a plurality of equidistant guide plates 73, and the side walls of the guide plates 73 are inclined; by fixing the supporting bottom plate 72 on the bottom wall of the driving shaft 21, the supporting bottom plate 72 and the guide plates 73 rotate together with the driving shaft 21, and the guide plates 73 therefore push the sliding rods 74 and the baffle plates 75 to move upward, so that a certain gap is generated between the sealing plate 71 and the filter screen 3, which facilitates the rotation of the filter screen 3. When the sliding rods 74 and the guide plates 73 are staggered, the sliding rods 74 and the sealing plate 71 will fall, and the sealing plate 71 will therefore fall back on the side wall of the filter screen 3, causing the filter screen 3 to produce a certain vibration amplitude, so that the impurities on the surface of the filter screen 3 vibrate and slide downward along the side walls of the filter screen 3, so that the filter screen 3 can rotate while improving the impurity treatment efficiency.

[0039] The specific working method is as follows: when rainwater enters the interior of the water inlet pipe 11 through the water trough 14, it will first fall on the side wall of the spiral plate 28, and the rainwater will flow downward in a spiral through the spiral plate 28, and then impact the side wall of the driving blade 22, so that the driving blade 22 drives the driving shaft 21 to rotate together, and under the cooperation of the two linkage flywheels 25 and the linkage belt 26, the driven shaft 24 rotates with the driving shaft 21, and the multi-link 41 is fixedly connected to the bottom end of the linkage flywheel 25 on the side wall of the driven shaft 24, and the pressing frame 44 fixedly installed at the bottom end of the load block 42 passes through the pressing groove 43 and extends to the inside of the driven shaft 24, so the multi-link 41 and the load block 42 will rotate with the driven shaft 24. As the multi-link 41 expands, the weight block 42 moves upward a certain distance as the multi-link 41 expands, causing the pressing frame 44 to push the inner shaft 45 and the extrusion rod 48 to move upward together. The extrusion rod 48 therefore pushes the transmission rod 46 and the linkage frame 49 to rotate along the inner side wall of the transmission groove 47, and the linkage frame 49 is fixedly installed on the side wall of the filter screen 3. Therefore, the position of the filter screen 3 inside the water inlet pipe 11 changes, and the pores on the filter screen 3 gradually increase in the counterclockwise direction. When the speed of the multi-link 41 is higher, the weight block 42 moves upward a greater distance, the transmission rod 46 rotates at a greater angle, and the pores on the filter screen 3 are larger. The part can be inside the water inlet pipe 11, so the filtering speed of rainwater can be adjusted according to the size of the rain. By fixing the fixing frame 61 on the side wall of the driven shaft 24, the fixing frame 61 can rotate with the driven shaft 24, and the convex plate 64 is stuck in the inside of the clamping groove 66, so the cleaning brush 55 will rotate with the connecting frame 56, so that the cleaning brush 55 cleans the surface of the filter 3 and scrapes off the impurities on the surface of the filter 3. The side wall of the filter 3 is inclined, and the impurities scraped by the cleaning brush 55 will slide along the side wall of the filter 3 to the inside of the collecting bucket 15, so that the collecting bucket 15 collects the impurities. Since the part of the filter 3 is inside the water inlet pipe 11 When the cleaning brush 55 contacts the side wall of the water inlet pipe 11 and cannot continue to rotate, the convex plate 64 retracts into the interior of the accommodating groove 62 due to the influence of resistance, so that the fixing frame 61 can continue to rotate. When the clamping groove 66 is separated from the clamping groove 66, since the position of the positioning plate 52 is fixed, the elasticity of the torsion spring 53 will drive the mounting plate 51 to rotate, and drive the cleaning brush 55 and the connecting frame 56 to return to their original positions until the convex plate 64 slides into the interior of the clamping groove 66 again, driving the connecting frame 56 to rotate, and repeatedly cleaning the surface of the filter screen 3 by the cleaning brush 55, removing impurities on the surface of the filter screen 3, and ensuring the filtering effect of the filter screen 3.
