Description

Technical Field

[0001] This invention relates to the field of river management, and specifically to a river cleaning device. Background Technology

[0002] River regulation, also known as "riverbed management," is an engineering measure to control and transform river channels. Erosion and siltation frequently occur in natural rivers, easily leading to water hazards and hindering water conservancy development. To meet the requirements of eliminating hazards and promoting benefits, appropriate measures must be taken to regulate river channels, including river channel management, dredging, and bank protection projects.

[0003] Current river management technologies typically involve the rapid removal of silt, debris, and gravel from the riverbed using large machinery such as excavators and riverbed cleaning vessels. However, for small rivers, due to poor water flow, the accumulation of silt, gravel, plastic bags, and other waste is more severe. Furthermore, bridges are frequently built in tributary sections of small rivers for transportation or cement pipes for water diversion. As the water flows, plastic bags, gravel, and other waste often become caught in bridge arches or pipes, causing blockages. These blockages can easily impede water flow in certain sections. Because the arches are small, large equipment cannot easily access them, requiring manual cleaning. This method is not only inefficient but also difficult and time-consuming to remove tangled weeds or waste stuck in rock walls. It also fails to clean debris located deep within the river or in areas where pipes bend. Therefore, a river cleaning device is proposed to address these problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the prior art, waste often accumulates in the arches of bridges or water pipes of small rivers, causing blockages. Large equipment is not suitable for small rivers, so manual cleaning is usually required, which is inefficient, time-consuming and labor-intensive, and it is impossible to clean up the waste accumulation in the bends of the pipes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a river cleaning device, including a base plate, a mounting box provided on the base plate, a horizontal mounting hole provided in the mounting box, a bearing provided in the horizontal mounting hole, and a first rotating cylinder with both ends extending beyond the end face of the mounting box provided in the bearing, a second rotating cylinder with both ends extending beyond the first rotating cylinder fixed in the first rotating cylinder by the bearing, and a third rotating cylinder with both ends extending beyond the second rotating cylinder fixed in the second rotating cylinder by the bearing, a first driving gear, a second driving gear and a third driving gear respectively fixed on the outer wall of the same side end of the first rotating cylinder, the second rotating cylinder and the third rotating cylinder, and a second driven gear and a third driven gear fixed on the other side end of the second rotating cylinder and the third rotating cylinder;

[0006] It also includes a U-shaped frame fixed to the outer wall of the other end of the first rotating drum, with the opening of the U-shaped frame facing away from the mounting box; it also includes a first connecting column and a second connecting column that are perpendicular to the side wall of the U-shaped frame and rotatable, the first connecting column and the second connecting column being fixed to the inner side of the two side walls of the U-shaped frame and facing each other; the end of the first connecting column is connected to the first steering gear, and the end of the second connecting column is connected to the second steering gear; the first steering gear meshes with the second driven gear, and the second driven gear drives the first steering gear to rotate; the middle of the first connecting column is provided with an L-shaped connecting rod bent towards the second connecting column, the end of the L-shaped connecting rod is provided with a connecting block, the connecting block has a rotating shaft passing through it laterally, a clamping assembly is fixed on the side of the rotating shaft away from the base plate, and a third steering gear is fixed on the side of the rotating shaft close to the base plate; the third steering gear meshes with the second steering gear, and the second steering gear meshes with the third driven gear;

[0007] It also includes drive components for driving the first drive gear, the second drive gear and the third drive gear to rotate respectively.

[0008] Specifically, the drive assembly includes a first rack, a second rack, and a third rack, which are movably disposed on and meshed with a base plate directly below the first drive gear, the second drive gear, and the third drive gear, respectively; it also includes a first guide rod cylinder, a second guide rod cylinder, and a third guide rod cylinder disposed on the base plate, which are connected to and drive the first rack, the second rack, and the third rack to move laterally.

[0011] Furthermore, a camera and an air nozzle facing directly in front of the camera are fixed to the end face of the clamping block away from the base plate. The air nozzle is connected to an external air pump through an air supply pipe.

Compared with manual clamping, it saves time and effort and has higher cleaning efficiency. At the same time, it can effectively adjust the angle according to the specific location of the waste in different parts of the pipe, effectively increasing the coverage area of ​​the clamping component, so that even places that are difficult to clean manually can be cleaned quickly.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, so as to provide a better understanding of the concept of the present invention, the technical problem solved, the technical features constituting the technical solution, and the technical effects brought about.

[0020] like Figures 1-3As shown, a river cleaning device includes a base plate 1, on which a mounting box 2 is provided. The mounting box 2 has a transverse mounting hole through a bearing. A bearing is provided in the transverse mounting hole, and a first rotating cylinder 31 with both ends extending beyond the end face of the mounting box 2 is provided in the bearing. A second rotating cylinder 32 with both ends extending beyond the first rotating cylinder 31 is fixed in the first rotating cylinder 31 through a bearing. A third rotating cylinder 33 with both ends extending beyond the second rotating cylinder 32 is fixed in the second rotating cylinder 32 through a bearing. A first driving gear 311, a second driving gear 321, and a third driving gear 331 are respectively fixed on the outer wall of the same side end of the first rotating cylinder 31, the second rotating cylinder 32, and the third rotating cylinder 33. A second driven gear 322 and a third driven gear 332 are fixed on the other side end of the second rotating cylinder 32 and the third rotating cylinder 33.

[0021] It also includes a U-shaped frame 4 fixed to the outer wall of the other end of the first rotating drum 31, with the opening of the U-shaped frame 4 facing away from the mounting box 2; it also includes a first connecting column 41 and a second connecting column 42 perpendicular to the side wall of the U-shaped frame 4 and rotatable, the first connecting column 41 and the second connecting column 42 respectively fixed to the inner side of the two side walls of the U-shaped frame 4 and facing each other; the end of the first connecting column 41 is connected to the first steering gear 411, and the end of the second connecting column 42 is connected to the second steering gear 421; the first steering gear 411 meshes with the second driven gear 322. The first steering gear 411 is driven to rotate by the second driven gear 322; the first connecting column 41 is provided with an L-shaped connecting rod 43 bent toward the second connecting column 42 in the middle, and a connecting block 44 is provided at the end of the L-shaped connecting rod 43. A rotating shaft 45 is passed through the connecting block 44 laterally. A clamping assembly is fixed on the side of the rotating shaft 45 away from the base plate 1, and a third steering gear 46 is fixed on the side of the rotating shaft 45 close to the base plate 1; the third steering gear 46 meshes with the second steering gear 421, and the second steering gear 421 meshes with the third driven gear 332.

[0022] It also includes drive components for driving the first drive gear 311, the second drive gear 321 and the third drive gear 331 to rotate respectively.

[0023] In this invention, the main principle is as follows: the first drive gear 311, the second drive gear 321, and the third drive gear 331 are driven to rotate by the drive assembly, which in turn drives the first rotating drum 31, the second rotating drum 32, and the third rotating drum 33 to rotate respectively. Since the first rotating drum 31, the second rotating drum 32, and the third rotating drum 33 are connected sequentially by bearings, their rotations are independent of each other. When the first rotating drum 31 rotates, it drives the U-shaped frame 4 to rotate along the axial direction of the first rotating drum 31, which in turn drives the L-shaped connecting rod 43 on the second connecting column 42 and the clamping assembly at the end of the L-shaped connecting rod 43 to rotate around the axial direction of the first rotating drum 31, thereby adjusting the initial angle of the clamping assembly.

[0024] When the second rotating drum 32 rotates, the second driven gear 322 at the end rotates together, driving the first steering gear 411 meshing with it to rotate in the vertical direction. The first steering gear 411 then drives the first connecting column 41 to rotate, causing the L-shaped connecting rod 43 to rotate around the axis of the first connecting column 41, thereby adjusting the angle of the clamping device in the horizontal direction to adapt to the clamping requirements of the pipe or bridge bend section and further increase the clamping area.

[0025] When the third rotating drum 33 rotates, the third driven gear 332 at the end drives the second steering gear 421 on the second connecting column 42 inside the U-shaped frame 4 to rotate. As the second steering gear 421 rotates vertically, it drives the third steering gear 46 at the end of the connecting block 44 to rotate horizontally around the axial direction, thereby causing the clamping assembly at the other end of the rotating shaft 45 to rotate horizontally around the axis of the rotating shaft 45. This arrangement is designed to work with the U-shaped frame 4 to further adjust the clamping angle of the clamping assembly, adapting to angle adjustments of the clamping assembly when the U-shaped frame 4 cannot rotate in complex environments. In the above process, the transmission between any gears can be achieved using bevel gear transmission. As a very mature existing technology, its specific structure will not be elaborated here.

[0026] In a preferred embodiment, the drive assembly includes a first rack 51, a second rack 52, and a third rack 53, which are movably mounted on and meshed with a base plate 1 directly below a first drive gear 311, a second drive gear 321, and a third drive gear 331, respectively. It also includes a first guide rod cylinder 61, a second guide rod cylinder 62, and a third guide rod cylinder 63 mounted on the base plate 1, which are connected to and drive the first rack 51, the second rack 52, and the third rack 53 to move laterally.

[0027] In this embodiment, a specific drive assembly structure is provided, wherein the first guide rod cylinder 61, the second guide rod cylinder 62, and the third guide rod cylinder 63 serve as power sources and are respectively connected to an external air pump, with separate air supply circuits for individual control. When the air supply circuit is connected, any one of the cylinders is controlled to operate by pushing or retracting, thereby pushing or pulling the rack, and driving the upper first drive gear 311, second drive gear 321, or third drive gear 331 to rotate forward or in reverse, thereby controlling the start and amplitude of rotation of the first rotating drum 31, the second rotating drum 32, and the third rotating drum 33.

[0028] In a preferred embodiment, the clamping assembly includes a horizontal electric actuator 71 fixedly connected to the connecting block 44, with a clamping block 72 fixed to the end of the horizontal electric actuator 71; it also includes two connecting rods 73 located on both sides of the horizontal electric actuator 71, one end of the two connecting rods 73 being hinged to the connecting block 44, and the other end being hinged to two L-shaped clamping rods 74 respectively; the L-shaped clamping rods 74 are hinged to the clamping block 72 at the corner.

[0029] In this embodiment, a specific structure and connection relationship of a clamping assembly are provided. The horizontal electric actuator 71 serves as the main power source for the clamping device. As the piston rod of the horizontal electric actuator 71 retracts inward, it causes the clamping block 72 to retract as well. At this time, the end of the L-shaped clamping rod 74 near the base plate 1 is rotated outward under the action of the connecting rod 73, causing the end of the L-shaped clamping rod 74 away from the base plate 1 to retract inward, thus achieving the clamping step. Simultaneously, the rotation of the aforementioned first rotating cylinder 31 and third rotating cylinder 33 can also drive the entire clamping assembly to rotate around the horizontal axis, thereby adjusting the position of the connecting rod 73 and the outwardly extending portion of the L-shaped clamping rod 74 to avoid potential obstacles. Conversely, when the horizontal electric actuator 71 controls the piston rod to extend, the end of the L-shaped clamping rod 74 away from the base plate 1 moves away from each other, thereby achieving the purpose of releasing the clamped object.

[0030] As a further embodiment, the opposing surfaces of the two L-shaped clamping rods 74 are provided with a plurality of clamping protrusions.

[0031] In this embodiment, clamping protrusions are provided on the opposing surfaces of the L-shaped clamping rod 74 to increase the clamping friction, thereby facilitating the stable removal of waste stuck in the gaps and stone walls.

[0032] As a further embodiment, a camera and an air nozzle facing directly in front of the camera are fixed to the end face of the clamping block 72 away from the base plate 1. The air nozzle is connected to an external air pump through an air supply pipe.

[0033] In this embodiment, a camera is set up to observe the accumulation of waste in front of the device. When the silt or debris accumulates severely, an air nozzle and air supply pipe circuit are set up to spray gas forward, thereby blowing away the waste or silt that is affecting the observation and ensuring that the situation can be observed in a timely manner.

[0034] In a preferred embodiment, the base plate 1 also has several vertical through holes, through which the base plate 1 is fixedly connected to the mobile vehicle body or hand handle.

[0035] In this embodiment, by providing a vertical through hole on the base plate 1, the base plate 1 is fixedly connected to the mobile vehicle body or the hand handle, thereby enabling convenient movement of the device.

[0036] In a preferred embodiment, the base plate 1 is provided with a raised top support platform 8, and the top support platform 8 is provided with three sliding grooves 81 with openings at both ends. The first rack 51, the second rack 52 and the third rack 53 are disposed in the sliding grooves 81.

[0037] In this embodiment, a specific method for moving the first rack 51, the second rack 52, and the third rack 53 is provided. The top support platform 8 serves as the mounting position for the first rack 51, the second rack 52, and the third rack 53, and is slightly higher than the base plate 1. Three parallel sliding grooves 81 with openings at both ends are formed on the top support platform 8 as mounting positions for the first rack 51, the second rack 52, and the third rack 53. This facilitates the movement of the first rack 51, the second rack 52, and the third rack 53 within the sliding grooves 81 under the drive of the first guide rod cylinder 61, the second guide rod cylinder 62, and the third guide rod cylinder 63, along the direction of the sliding grooves 81, thereby achieving the purpose of driving the first drive gear 311, the second drive gear 321, and the third drive gear 331 to rotate.

[0038] The terms "connection" and "fixing" appearing in the description of this invention can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this invention should be understood according to the specific circumstances.
