For this reason, we designed a floating object cleaning device acting on the ditch. The device can clean the floating objects on the water surface by the natural flow of water. The device has low cost and does not require frequent human operation. Summary of the invention

[0004] In order to overcome the problems raised by the above-mentioned background technology, the present invention provides a device for cleaning floating objects on the water surface of a ditch.

[0005] The technical solution of the present invention is as follows:

[0006] A device for cleaning floating objects on the surface of a ditch, comprising:

[0007] A high-level water tank, a low-level water tank and a connecting water tank are connected in sequence, and water passes through the high-level water tank, the connecting water tank and the low-level water tank in sequence; the bottom height of the high-level water tank is greater than the bottom height of the low-level water tank;

[0008] A side water trough and a drainage pipe, wherein the side water trough is provided with an installation groove inside, and the side water trough is provided with at least one group on the side of the high-level water trough, wherein one group of side water troughs is symmetrically arranged at both ends of the outer side wall of the high-level water trough, and the bottom height of the side water trough is between the water surface height inside the high-level water trough and the bottom height of the low-level water trough; one end of the drainage pipe is connected to the bottom of the side water trough, and the other end is connected to the bottom end of the low-level water trough, wherein,

[0009] A water tank is installed inside the installation groove; a connecting hole is provided at the bottom of the water tank, a movable plate covering the connecting hole is installed at the bottom of the water tank, the movable plate is pressed and fitted to the bottom of the water tank through an elastic mechanism, and a convex block is provided at the bottom of the installation groove, and when the water tank slides to the bottom of the installation groove, the convex block opens the movable plate so that the inside of the water tank is connected with the inside of the installation groove through the connecting hole;

[0010] It also includes a cleaning plate, at least two of which are provided, and the two cleaning plates are symmetrically arranged on the top of the two side walls of the high-level water tank, one end of the cleaning plate is obliquely inserted into the high-level water tank, and the other end is rotatably installed on a support member, the support member is fixed on the top of the side water tank, and the top of the water tank is fixedly connected to one end of the cleaning plate located inside the high-level water tank through a first rope;

[0011] It also includes a rotating column, which is vertically embedded in the side wall of the high-level water tank, and the rotating column is rotatably connected to the side wall of the high-level water tank. The side wall of the rotating column is provided with a drainage hole connected to the two ends of the side wall of the high-level water tank. The water in the high-level water tank enters the water tank through the drainage hole. The top of the water tank is fixedly connected to one end of the second rope, and the other end of the second rope is wound around and fixed to the side of the rotating column;

[0012] It also includes a limit door, which is symmetrically arranged at both ends of the inner wall of the water inlet of the high-level water tank. The limit door is fixedly connected to the side of the rotating column. When the water tank is at the top, the limit door opens in the direction of water flow.

[0013] In the above embodiment, water passes through the high-level water tank, the connecting water tank and the low-level water tank in sequence. Some floating objects such as garbage bags and branches will enter the high-level water tank. The water flows into the water diversion bucket through the drainage hole and is introduced into the water tank by the water diversion bucket. As the water inside the water tank continues to increase, the first rope is pressed down at both ends of the water tank. When the overall gravity of the water tank and the water inside it reaches a critical value, the cleaning plate is slowly lifted and the floating objects on the water surface are cleared. As the angle of the cleaning plate is continuously increased, the floating objects above it slide to the outside of the device. While the water tank slowly moves downward, the second rope is pulled, and the second rope pulls the rotating column to rotate. At this time, the limit doors on both sides are gradually closed during the rotation of the rotating column to prevent floating objects from entering the high-level water tank. The connecting hole is located inside the side wall of the high-level water tank and no further water is discharged into the water tank. When the water tank descends to the lowest point of the side tank When the water is at the low end, the protrusion at the bottom of the side water tank will pass through the connecting hole and push the movable plate upward, so that the water inside the water tank can enter the bottom of the side water tank through the connecting hole and be discharged to the downstream low-level water tank through the drain pipe. When the overall weight of the water tank and the water inside is less than the critical value, the water tank moves up under the gravity of the clearing plate. At this time, the movable plate is reset under the action of the elastic structure and blocks the connecting hole. The limit door will also open quickly under the impact of the water flow without traction, so that the rotating column pulls the second rope to reset, allowing the floating objects to enter the high-level water tank again. As the device is reset to the initial state as a whole, the drain hole is connected again, and the water enters the middle water tank through the drain hole. By arranging multiple groups of the above-mentioned structures on both sides of the high-level water tank and repeating the above-mentioned actions again, the device can cyclically clean the floating objects in the ditch to prevent the ditch from being blocked by too many floating objects.

[0014] Preferably, a first pulley is also provided, and two first pulleys are provided on the top of a side water tank, and the two first pulleys are respectively fixed at the two ends of the length direction of the side water tank through supports, and two first ropes are provided, and one end of the two first ropes is respectively fixedly connected to the two ends of the length direction of the water tank, and the other ends both pass around the first pulley and are fixedly connected to one end of the clearing plate located inside the high-position water tank.

[0015] Preferably, it also includes a second pulley, which is arranged on the top of a side water tank, one end of the second rope is fixedly connected to the top of the water tank, and the other end passes around the second pulley and is fixedly connected to the rotating column.

[0016] Preferably, a plurality of through holes are provided on the surface of the limiting door.

[0017] Preferably, a groove is provided on the top of the cleaning plate on one side inside the high-level water tank.

[0018] Preferably, a plurality of through holes penetrating the cleaning plate are provided at the bottom of the groove.

[0019] Preferably, it also includes a water diversion bucket, which is fixed on the outer side wall of the high-level water tank, with the water outlet of the drainage hole facing the water inlet side of the water diversion bucket and the water outlet side of the water diversion bucket facing the water storage tank.

[0020] Preferably, the elastic mechanism includes a limiting column and a spring, the spring is sleeved on the limiting column, the limiting column passes through the four corners of the movable plate, and the movable plate is movably connected to the limiting column.

[0021] Preferably, the angle between the cleaning plate and the ground does not exceed 45°.

[0022] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0023] By setting up a high-level water tank, a low-level water tank, a connecting water tank, a drain pipe and a side water tank, the water in the high-level water tank can flow into the side water tank and into the low-level water tank through the drain pipe, so as to avoid water accumulation in the side water tank, which may cause the device to fail to operate;

[0024] By setting a water tank, a first pulley, a first rope and a cleaning plate, when water gradually enters the water tank and exceeds the critical value of the force used to lift the cleaning plate, the water tank moves downward, and the cleaning plate is lifted by the first rope, and the cleaning plate lifts the floating objects on the water surface. When the cleaning plate is tilted to the maximum angle, the floating objects slide from the top to the outside of the device. The first pulley is used to pull the first rope to ensure that the direction of the force when the first rope is pulled downward is correct, and at the same time, the wear of the first rope during operation can be reduced;

[0025] By setting a limit gate, a rotating column, a second pulley and a second rope, in the initial state, the limit gate opens under the action of the water flow, at which time the drainage hole on the rotating column introduces the water in the high-level water tank into the water storage tank. When the water storage tank moves downward, the rotating column is driven to rotate by the second rope, so that the drainage hole is located inside the side wall of the high-level water tank, and the drainage is disconnected. At this time, the limit gates are arranged side by side under the action of the second rope, and prevent floating objects from further entering the high-level water tank. Later, when the water storage tank rises, due to the impact of the water flow on the limit gate, the second rope can be wound around the rotating column again, and the rotating column is also reset to the initial state, and the drainage hole works again to enter the next cycle;

[0026] By setting the protrusion, movable plate, limit column and spring, when the water tank drops to the lowest end of the side tank, the protrusion at the bottom of the side tank will pass through the connecting hole and push the movable plate upward, so that the water inside the water tank can enter the bottom of the side tank through the connecting hole and be discharged to the downstream low-level tank through the drain pipe. The overall gravity of the water tank drops and it will rise again to reset.

[0027] By setting the grooves, the floating objects can be conveniently placed in the grooves in cooperation with the digging action when the cleaning plate rotates;

[0028] By setting a through hole on the limit door, water can still pass through when the limit door is closed, avoiding excessive water pressure that makes it difficult to close the limit door;

[0029] By arranging through holes in the grooves, the cleaning plate can be lifted with less force, thereby preventing excessive water from accumulating on the cleaning plate, causing the cleaning plate to be lifted slowly. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figure 8As shown, the side trough 5 and the drain pipe 4, the side trough 5 is provided with an installation groove 6, and at least one group of side troughs 5 is provided on the side of the high-level trough 1, and a group of side troughs 5 are symmetrically arranged at both ends of the outer wall of the high-level trough 1, and the bottom height of the side trough 5 is between the water surface height inside the high-level trough 1 and the bottom height of the low-level trough 2; one end of the drain pipe 4 is connected to the bottom of the side trough 5, and the other end is connected to the bottom end of the low-level trough 2, so that the water surface height in the high-level trough 1 is higher than the side trough 5, which is convenient for setting the drainage hole 17, allowing water to naturally flow into the side trough 5, and at the same time, the water at the bottom of the side trough 5 can flow to the low-level trough 2 below through the drain pipe 4, avoiding water accumulation in the side trough 5.

[0048] like Figure 1 , Figure 6 and Figure 7 As shown, a water tank 7 is installed inside the installation groove 6; a connecting hole 19 is provided at the bottom of the water tank 7, and a movable plate 20 covering the connecting hole 19 is installed at the bottom end of the water tank 7. The movable plate 20 is squeezed and fitted to the bottom end of the water tank 7 through an elastic mechanism. A protrusion 16 is provided at the bottom end of the installation groove 6. When the water tank 7 slides to the bottom of the installation groove 6, the protrusion 16 opens the movable plate 20 so that the inside of the water tank 7 is connected with the inside of the installation groove 6 through the connecting hole 19.

[0049] like Figure 1-3 As shown, it also includes a cleaning plate 10, at least two cleaning plates 10 are provided, and the two cleaning plates 10 are symmetrically arranged on the top of the two side walls of the high-level water tank 1. One end of the cleaning plate 10 is obliquely inserted into the high-level water tank 1, and the other end is rotatably installed on the support member, which is fixed on the top of the side water tank 5. The top of the water tank 7 is fixedly connected to the end of the cleaning plate 10 located inside the high-level water tank 1 through a first rope 12. The cleaning plate 10 is made of lightweight materials, such as pillars, plastics, etc. When the cleaning plate 10 rotates strictly with the support member, an excavation action is formed to excavate floating objects on the water surface.

[0050] like Figure 1-3 , Fig. 9 , Fig.10 As shown, it also includes a rotating column 9, which is vertically embedded in the side wall of the high-level water tank 1, and the rotating column 9 is rotatably connected to the side wall of the high-level water tank 1. A drainage hole 17 connecting the two ends of the side wall of the high-level water tank 1 is provided on the side wall of the rotating column 9. The water in the high-level water tank 1 enters the water tank 7 through the drainage hole 17. The top of the water tank 7 is fixedly connected to one end of the second rope 14, and the other end of the second rope 14 is wound around and fixed on the side of the rotating column 9. In the initial state, the other end of the second rope 14 is wound around and fixed on the side of the rotating column 9. In the working state, the water tank 7 is located at the bottom of the installation groove 6, and the second rope 14 pulls the rotating column 9 to rotate. At this time, the drainage hole 17 is located in the side wall of the high-level water tank 1, and the drainage stops. At the same time, the limit door 8 is closed under the traction action to intercept floating objects on the upper end of the water surface.

[0051] It also includes a limit door 8, which is symmetrically arranged at both ends of the inner wall of the water inlet of the high-level water tank 1. The limit door 8 is fixedly connected to the side of the rotating column 9. When the water tank 7 is at the top, the limit door 8 opens in the direction of water flow.

[0052] A first pulley 11 is also provided. Two first pulleys 11 are provided on the top of a side water tank 5. The two first pulleys 11 are respectively fixed at both ends of the length direction of the side water tank 5 through supports. Two first ropes 12 are provided. One end of the two first ropes 12 is respectively fixedly connected to the two ends of the length direction of the water tank 7, and the other ends both pass around the first pulley 11 and are fixedly connected to one end of the clearing plate 10 located inside the high-level water tank 1.

[0053] It also includes a second pulley 13 , which is arranged at the top of a side water tank 5 . One end of a second rope 14 is fixedly connected to the top of the water tank 7 , and the other end passes around the second pulley 13 and is fixedly connected to the rotating column 9 .

[0054] The first pulley 11 and the second pulley 13 can apply traction to the first rope 12 and the second rope 14 respectively, so that the first rope 12 and the second rope 14 are subjected to force in the correct direction, and at the same time, the first rope 12 and the second rope 14 can be protected to avoid excessive friction of the ropes.

[0055] The surface of the limiting door 8 is provided with a plurality of through holes, and when the limiting door 8 is closed, water can still pass through, thereby preventing the limiting door 8 from being difficult to close due to excessive water pressure.

[0056] like Figure 2 As shown, a groove 18 is provided on the top of the cleaning plate 10 on one side inside the high-level water tank 1 . The groove 18 cooperates with the digging action when the cleaning plate 10 rotates, so that floating objects can be easily placed in the groove 18 .

[0057] like Figure 4-5 As shown, a plurality of through holes penetrating the cleaning plate 10 are provided at the bottom of the groove 18, so that the cleaning plate 10 requires less force when rising, and avoids excessive water accumulation on the cleaning plate 10, causing the cleaning plate 10 to be lifted slowly.

[0058] It also includes a water diversion bucket 15, which is fixed on the outer side wall of the high-level water tank 1, and the water outlet of the drainage hole 17 is opposite to the water inlet side of the water diversion bucket 15, and the water outlet side of the water diversion bucket 15 faces the water tank 7.

[0059] The elastic mechanism includes a limiting column 21 and a spring 22 . The spring 22 is sleeved on the limiting column 21 . The limiting column 21 passes through four corners of the movable plate 20 , and the movable plate 20 is movably connected to the limiting column 21 .

[0060] The angle between the cleaning plate 10 and the ground is no more than 45°.

[0061] The workflow of the present invention is as follows:

[0062] Water passes through the high-level water tank 1, the connecting water tank 3 and the low-level water tank 2 in sequence. Some floating objects such as garbage bags and branches will enter the high-level water tank 1. The water flows into the water diversion bucket 15 through the drainage hole 17 and is introduced into the water tank 7 by the water diversion bucket 15. The first rope 12 passes around the first pulley 11, and the other end is connected to the port of the cleaning plate 10 located in the high-level water tank 1. As the water inside the water tank 7 continues to increase, the two ends of the water tank 7 press down the first rope 12. When the water tank 7 and the water inside it are completely weighed, the first rope 12 is pressed down. When the force reaches the critical value, the clearing plate 10 is slowly lifted and the floating objects on the water surface are cleared. As the angle of the clearing plate 10 is continuously raised, the floating objects above it slide to the outside of the device. When the water tank 7 slowly moves down, the second rope 14 bypassing the second pulley 13 is pulled. The second rope 14 pulls the rotating column 9 to rotate. At this time, the limit doors 8 on both sides are gradually closed during the rotation of the rotating column 9 to prevent the floating objects from entering the high-level water tank 1, and the connecting hole 19 is located inside the side wall of the high-level water tank 1, and no further water is discharged into the water tank 7; when the water tank 7 drops to the lowest end of the side tank 5, the protrusion 16 at the bottom of the side tank 5 will pass through the connecting hole 19 and push the movable plate 20 upward, so that the water inside the water tank 7 can enter the bottom of the side tank 5 through the connecting hole 19, and be discharged to the downstream low-level water tank 2 through the drain pipe 4. When the overall weight of the water tank 7 and the water inside is less than the critical value, the water tank 7 moves up under the gravity of the clearing plate 10. At this time, the movable plate 20 is at the limit column 21 and the spring 22 are reset under the action of force, and the connecting hole 19 is blocked. The limit door 8 will also open quickly under the impact of water flow without traction, so that the rotating column 9 pulls the second rope 14 to reset, allowing the floating objects to enter the high-level water tank 1 again. As the device is reset to the initial state as a whole, the drain hole 17 is connected again, and water enters the middle water tank 7 through the drain hole 17, and the above actions are repeated again. The device can circulate and clean the floating objects in the ditch to prevent the ditch from being blocked by too many floating objects.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
