[0010] Optionally, a permeable cloth is wound and connected to one end of the winding cylinder located inside the end plate. The upper end of the permeable cloth slidably penetrates through the inner wall of the end plate. One end of the permeable cloth located outside the end plate is fixed to the upper surface of the main filter plate. The front and back widths of the permeable cloth are equal to the front and back widths of the main filter plate.

[0011] Optionally, the collection structure includes a storage box and a bent pipe. A water storage tank is installed at the lower end of the storage box.

The movable tube located in the vertical part of the L-shaped bend of the conveyor belt is located inside the opening at the back surface of the water collecting tank.

[0016] In summary, the present invention includes the following beneficial technical effects: 1. By providing components such as an electric telescopic rod, a double-headed monitoring controller, a filtering structure, and a collecting structure, the filtering structure filters the passing water flow, and the dirt is blocked above the filtering structure. Then, the dirt slides downward under the action of gravity to the outer end of the filtering structure located outside the water collecting tank. After the double-headed monitoring controller detects that more dirt accumulates at the outer end of the filtering structure, the electric telescopic rod extends to control the filtering structure to move above the adjacent collecting structure below, and the dirt in the filtering structure is put into the adjacent collecting structure below. The collecting structure with added dirt moves downward under the action of gravity to transport the dirt, effectively preventing the dirt from continuously accumulating on the upper side of the filtering structure and affecting subsequent filtering.

[0017] 2. By providing components such as an elastic pull rope A, a movable filter plate, an extension plate frame, and a water baffle, the elastic pull rope A gradually becomes taut during the movement of the main filter plate to the outside of the water collecting tank. When the main filter plate continues to move after the elastic pull rope A becomes taut, the elastic pull rope A is gradually pulled from the surface of the winding wheel A, driving the movable filter plate to rotate and open, so that the dirt on the upper side of the movable filter plate falls into the extension plate frame. Before the blocking plate moves above the adjacent lower storage box, the blocking plate blocks the dirt falling into the extension plate frame. During the movement of the extension plate frame, the elastic pull rope B is first straightened, and then when the extension plate frame continues to move, the elastic pull rope B is pulled out from the surface of the winding wheel B, gradually pulling the blocking plate to rotate parallel to the extension plate frame. At this time, the blocking plate moves above the storage box, effectively preventing the dirt on the upper sides of the main filter plate and the extension plate frame from falling outside the storage box.

[0018] 3. The present invention is provided with components such as a storage box, a bent pipe, a water storage tank, a movable pipe, and a water collection box. After the stolen goods fall into the interior of the storage box, the dirty water in the storage box flows from the water-permeable surface at the bottom of the storage box into the water storage tank. The water in the water storage tank flows into the water collection box through the bent pipe and the movable pipe, reducing the water content in the dirt and facilitating the subsequent treatment of the dirt. When the movable pipe and the bent pipe follow the conveyor belt and turn and move towards the water collection box, the movable pipe contacts the eight-shaped inclined surface of the water collection box, and the movable pipe is pushed into the bent pipe, enabling the movable pipe to disengage from the water collection box.

[0019] 4. The present invention is provided with a gear and a toothed plate. When the storage box follows the conveyor belt and moves to the horizontal part above the L-shaped bend, the gear drives the storage box to rotate around the corresponding bent pipe and the through shaft by meshing with the toothed plate. The storage box pours the dirt inside onto the discharge plate during rotation, reducing the residue of the dirt in the storage box. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0022] The following will further elaborate on the present invention in conjunction with the attached Figures 1-9 drawings for a more detailed description.

[0023] An embodiment of the present invention discloses a rainfall drainage structure for building construction. As Figures 1-9 shown, it includes a water collection tank 1. Inside the water collection tank 1, there is a filtering structure 4 with one end extending outside the water collection tank 1 and capable of opening and closing for discharging materials. The filtering structure 4 can permeate water while blocking dirt. The filtering structure 4 is located at the outer end of the water collection tank 1 and can be opened. An electric telescopic rod 2 parallel to the filtering structure 4 is installed on the front surface of the water collection tank 1. The telescopic end of the electric telescopic rod 2 is connected to the outer end of the filtering structure 4 located outside the water collection tank 1. A double-headed monitoring controller 3 is installed on the outer surface of the water collection tank 1 and above the filtering structure 4. The double-headed monitoring controller 3 controls the telescopic movement of the electric telescopic rod 2.

[0024] The filtering structure 4 includes a main filter plate 41 and a movable filter plate 42. One side of the water collection tank 1 is open. The main filter plate 41 is slidably inserted into the opening of the water collection tank 1, enabling the main filter plate 41 to move along the inclined direction of the main filter plate 41.

[0025] On the inner side of the main filter plate 41 located inside the water collection tank 1, there is an end plate 413. The upper end of the end plate 413 is inclined. The upper surface of the end plate 413 is parallel to the main filter plate 41. Inside the end plate 413, there is a winding cylinder 414. Both ends of the winding cylinder 414 rotatably penetrate the inner walls on both sides of the end plate 413. The water collection tank 1 is rotatably sleeved on both ends of the winding cylinder 414. One end of the winding cylinder 414 located outside the water collection tank 1 is elastically torsionally connected to the water collection tank 1. One end of the winding cylinder 414 located inside the end plate 413 is wound and connected with a permeable cloth 415. The material of the permeable cloth 415 allows water to pass through. The elastic connection between the winding cylinder 414 and the water collection tank 1 has a tendency to wind the permeable cloth 415. The upper end of the permeable cloth 415 slidably penetrates the inner wall of the end plate 413. One end of the permeable cloth 415 located outside the end plate 413 is fixed to the upper surface of the main filter plate 41. When the main filter plate 41 moves towards the outside of the water collection tank 1, the permeable cloth 415 is gradually pulled out from the surface of the winding cylinder 414. At the same time, the connection between the winding cylinder 414 and the water collection tank 1 can ensure that the permeable cloth 415 is in a taut state. The front and rear widths of the permeable cloth 415 are equal to the front and rear widths of the main filter plate 41, enabling the permeable cloth 415 to block the part after the movement of the main filter plate 41.

[0026] The main filter plate 41 is located at the outer end of the water collection tank 1 with one end lower than the other end. One end of the movable filter plate 42 close to the water collection tank 1 is elastically rotatably connected to the main filter plate 41. The elastic connection between the movable filter plate 42 and the main filter plate 41 has a tendency to drive the movable filter plate 42 to be parallel to the main filter plate 41. The main filter plate 41, the electric telescopic rod 2 and the movable filter plate 42 are arranged in parallel. The telescopic end of the electric telescopic rod 2 is fixed to the main filter plate 41. When the double-headed monitoring controller 3 detects that there is a large amount of dirt accumulation on the outer end of the main filter plate 41 and the upper side of the movable filter plate 42, the double-headed monitoring controller 3 controls the electric telescopic rod 2 to extend.

[0027] A extension plate frame 411 is fixed below one end of the main filter plate 41 located outside the water collection tank 1. A water baffle 412 is slidably inserted between the extension plate frame 411 and the movable filter plate 42. The water baffle 412 is fixed to the water collection tank 1. The water baffle 412 can effectively prevent water from flowing to the outside of the water collection tank 1. The distance between the extension plate frame 411 and the water collection tank 1 is greater than the distance between the main filter plate 41 and the water collection tank 1, so that the extension plate frame 411 can first move to the upper side of the collection structure 6. One end of the extension plate frame 411 away from the water collection tank 1 is in an open and concave shape. The length of the movable filter plate 42 is less than the concave depth of the extension plate frame 411, so that the movable filter plate 42 will not be blocked by the inner bottom wall of the extension plate frame 411 when moving downward in the extension plate frame 411.

[0028] A shielding frame 43 is installed on the upper surface of the main filter plate 41. The shielding frame 43 is arranged in a right-angled U shape. One end of the shielding frame 43 located inside the water collection tank 1 is open. The shielding frame 43 can effectively prevent dirt from leaving the range of the main filter plate 41.

[0029] A winding wheel A44 is concentrically installed on the connecting shaft of the movable filter plate 42 and the water collection tank 1. An elastic pull rope A45 is wound around the circumferential surface of the winding wheel A44. The elastic pull rope A45 extends from the lower side of the winding wheel A44 and is fixed to the water collection tank 1. When the main filter plate 41 moves outward from the water collection tank 1, the elastic pull rope A45 is gradually straightened first. When the main filter plate 41 continues to move after the elastic pull rope A45 is straightened, the elastic pull rope A45 is gradually pulled from the surface of the winding wheel A44, driving the movable filter plate 42 to rotate and open, so that the dirt on the upper side of the movable filter plate 42 falls into the extension plate frame 411. One end of the extension plate frame 411 away from the water collection tank 1 is elastically rotatably connected with a blocking plate 4111. The blocking plate 4111 has a tendency to be arranged in a V shape with the extension plate frame 411 under the elastic connection of the extension plate frame 411. A winding wheel B4112 is concentrically installed on the connecting shaft of the blocking plate 4111 and the extension plate frame 411. An elastic pull rope B4113 is wound around the circumferential surface of the winding wheel B4112. The elastic pull rope B4113 extends from the lower side of the winding wheel B4112 and is fixed to the water collection tank 1.

[0030] On one side of the water collecting tank 1 where the filtering structure 4 extends, there are two conveyor belts 5. The conveyor belts 5 are connected to the water collecting tank 1 through transmission wheels. During the rotation of the conveyor belts 5, they can drive the transmission wheels to rotate. An elastically rotatable collecting structure 6 is installed between the two conveyor belts 5. The collecting structure 6 includes a storage box 61 and a bent pipe 62. After the double-headed monitoring controller 3 detects that there is more dirt in the storage box 61 under the baffle 4111, it can control the electric telescopic rod 2 to contract once. Then, the storage box 61 with added dirt moves downward under gravity, synchronously driving the conveyor belt 5 to rotate. At the same time, after the double-headed monitoring controller 3 detects that there is less dirt on the upper sides of the main filter plate 41 and the movable filter plate 42, it controls the electric telescopic rod 2 to contract. A water storage tank 63 is installed at the lower end of the storage box 61. The bent pipe 62 is connected to the water storage tank 63. The communicating surface between the storage box 61 and the water storage tank 63 is a water-permeable surface. The water in the dirt falling into the storage box 61 flows from the water-permeable surface at the bottom of the storage box 61 into the water storage tank 63. The lower end of the bent pipe 62 bends forward and then rotates through the end face of the adjacent conveyor belt 5. A through shaft 64 is fixed to the back of the bent pipe 62. The through shaft 64 is coaxial with the forward-bent end of the bent pipe 62. The rear end of the through shaft 64 rotates through the front of the adjacent conveyor belt 5. Before the baffle 4111 moves to the upper side of the adjacent lower storage box 61, the baffle 4111 blocks the dirt falling in the extension plate frame 411. During the movement of the extension plate frame 411, the elastic pull rope B4113 is first straightened, and then when the extension plate frame 411 continues to move, the elastic pull rope B4113 is pulled out from the surface of the winding wheel B4112, gradually pulling the baffle 4111 to rotate parallel to the extension plate frame 411. At this time, the baffle 4111 moves above the storage box 61, facilitating the dirt in the extension plate frame 411 to fall into the storage box 61.

[0031] A gear 65 is coaxially fixed at one end of the through shaft 64 located behind the conveyor belt 5. The gear 65 is elastically torsionally connected to the adjacent conveyor belt 5. The elastic connection between the gear 65 and the conveyor belt 5 has the function of driving the corresponding storage box 61 to have its opening facing upward when it rotates to the vertical part of the L-shaped bend of the conveyor belt 5. A toothed plate 66 is provided at the L-shaped annular horizontal turning part at the lower end of the conveyor belt 5. The toothed plate 66 is located behind the two conveyor belts 5 and is fixed to the water collecting tank 1. The bottom surface of the gear 65 located above the bend of the conveyor belt 5 is tangent to the upper surface of the toothed plate 66. When the gear 65 rotates to the horizontal part on the upper side of the L-shaped conveyor belt 5, the gear 65 meshes with the toothed plate 66. The meshing of the gear 65 and the toothed plate 66 can exert a resistance on the rotation of the conveyor belt 5, reducing the rotation speed of the conveyor belt 5 under the gravity of the dirt inside the storage box 61, so that after there is more dirt in the storage box 61 under the extension plate frame 411 and the electric telescopic rod 2 contracts and moves, the descending height of the storage box 61 does not exceed the distance between two adjacent storage boxes 61, ensuring that after the electric telescopic rod 2 extends again, the baffle 4111 can be inserted between the two adjacent upper storage boxes 61.

[0032] The conveyor belt 5 is arranged in an L-shaped loop. There is a discharge plate 7 on one side of the water collection tank 1, and the discharge plate 7 is located on the inner ring side of the conveyor belt 5.

[0033] The discharge plate 7 is located on the inner ring side of the conveyor belt 5. The discharge plate 7 is located below the horizontal part of the L-shaped bend of the conveyor belt 5 and below the toothed plate 66. The number of teeth of the toothed plate 66 is equal to the number of teeth of the gear 65. During the meshing of the gear 65 and the toothed plate 66, the storage box 61 can be driven to rotate one week around the axis of the gear 65. During one rotation of the storage box 61, the dirt inside the storage box 61 with the opening facing down can fully fall onto the discharge plate 7.

[0034] The elbow pipe 62 is elastically and slidably inserted with a movable pipe 621 at the front end of the conveyor belt 5.

[0035] There is a water collection tank 622 on the front side of the water collection tank 1. The water collection tank 622 is located on the front side of the vertical part of the L-shaped bend of the conveyor belt 5. The upper end and the upper part of the back surface of the water collection tank 622 are both open. The movable pipe 621 can move from the opening on the upper side of the water collection tank 622 to the inside of the water collection tank 622. The back opening of the water collection tank 622 is distributed in an eight-shaped manner. The lower end of the back opening of the water collection tank 622 is located below the upper horizontal part of the L-shaped bend of the conveyor belt 5. The movable pipe 621 located at the vertical part of the L-shaped bend of the conveyor belt 5 is located inside the back opening of the water collection tank 622. The water in the water storage tank 63 flows into the water collection tank 622 through the elbow pipe 62 and the movable pipe 621. When the movable pipe 621 and the elbow pipe 62 follow the conveyor belt 5 and turn and move towards the water collection tank 1 side, the movable pipe 621 is pushed into the elbow pipe 62 by contacting the eight-shaped inclined surface of the water collection tank 622, so that the movable pipe 621 can be separated from the water collection tank 622.

[0036] The working principle is as follows: The collected rainwater flows in from the upper end of the water collection tank 1. The water flow drives the dirt to pass through the inclined filter structure 4. The filter structure 4 filters the passing water flow, and the dirt is blocked above the filter structure 4. The dirt slides under the action of gravity towards the outer end of the filter structure 4 located outside the water collection tank 1, so that the dirt gradually accumulates at the outer end of the filter structure 4 located outside the water collection tank 1. After the double-headed monitoring controller 3 detects that more dirt has accumulated at the outer side end of the filter structure 4, it controls the electric telescopic rod 2 to extend and controls the filter structure 4 to move above the adjacent lower collection structure 6, and puts the dirt in the filter structure 4 into the interior of the adjacent lower collection structure 6. The collection structure 6 with added dirt moves downward under the action of gravity to transport the dirt. When the collection structure 6 follows the conveyor belt 5 and moves to the upper horizontal part of the L-shaped, the dirt inside the collection structure 6 falls onto the discharge plate 7, effectively preventing the dirt from always accumulating on the upper side of the filter structure 4 and affecting subsequent filtration.

[0037] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
