[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] In order to solve the technical problems in the prior art that the passage of ships is caused inconvenience and the system cannot be adaptively adjusted according to the changes in the water level of the river, the present invention provides a river garbage cleaning system that can avoid ships to facilitate the passage of ships and can also be adaptively adjusted according to the changes in the water level so that the cleaning device is always on the water surface.

[0022] See also Figure 1 , Figure 1 It is a schematic structural diagram of a river garbage cleaning system in one embodiment of the present invention.

[0023] The present invention provides a river garbage cleaning system, comprising a cleaning device 1, a driving device 2 and a recovery device 3, wherein the cleaning device 1 floats on the river surface along the width direction of the river channel 200, one end of the cleaning device 1 is a recovery end, and the cleaning device 1 is used to intercept garbage on the river surface and gather the garbage to the recovery end, wherein the cleaning device 1 is movably arranged in the horizontal direction and the vertical direction so that the position of the cleaning device 1 in the width direction and the vertical direction of the river channel 200 is adjustable; the driving device 2 is connected to the cleaning device 1, and the driving device 2 is used to drive the cleaning device 1 to move; and the recovery device 3 is arranged on one side of the river channel 200 and corresponds to the recovery end, and the recovery device 3 is used to recover garbage located at the recovery end.

[0024] In this embodiment, the cleaning device 1 is arranged horizontally on the water surface of the river channel 200, and it can intercept garbage and gather the garbage at the recovery end, and the cleaning device 1 can also move in the vertical direction and in the horizontal direction. When it is necessary to intercept garbage, the cleaning device 1 is arranged on the river channel 200 to gather the garbage to the recovery end, and then the recovery device 3 recycles the garbage at the recovery end. When a ship needs to pass, the driving device 2 drives the cleaning device 1 to move in the horizontal direction, so that it moves to one side of the river channel 200 to avoid the ship, thereby facilitating the passage of the ship. After the ship passes, the driving device 2 drives the cleaning device 1 to recover the initial position and continue to intercept garbage. When the water level of the river channel 200 changes, the driving device 2 can drive the cleaning device 1 to move in the vertical direction, so that the cleaning device 1 is always on the water surface, avoiding the interception failure due to the change of water level.

[0025] In one embodiment, the cleaning device 1 includes a plurality of baffle plates 11 spaced apart along the width direction of the river channel 200, and two adjacent baffle plates 11 are connected by a connecting rope 12, wherein a plurality of blades 112 are provided on the outer periphery of the baffle plate 11 so that the baffle plate 11 can rotate under the action of the water flow.

[0026] In this embodiment, the blocking disk 11 can float on the water surface, and the connecting rope 12 is connected between two adjacent blocking disks 11, so that the multiple blocking disks 11 are linearly connected together, and the blocking disks 11 located at both ends of the multiple blocking disks 11 are connected to the driving device 2, so that the multiple blocking disks 11 are driven to move through the driving device 2 and the connecting rope 12, and the circumference of the blocking disk 11 is evenly distributed with inclined blades 112, the blades 112 are located below the water surface, and the blades 112 are arranged in an arc shape. When the river water flows, the blades 112 can be moved to drive the blocking disk 11 to rotate along its own axis, and the rotation direction of the multiple blocking disks 11 is consistent. During the rotation of the blocking disk 11, the garbage in contact with the blocking disk 11 can be moved to one side of the river channel 200 (that is, the recovery end) under the rotation of the blocking disk 11, which is conducive to the recovery device 3 to recover the intercepted garbage.

[0027] In one embodiment, the distance between two adjacent blocking disks 11 is half of the diameter of the blocking disk 11 .

[0028] In this embodiment, since the blocking disk 11 can be rotatably arranged along its own axis, the plurality of blocking disks 11 need to be arranged at intervals. If the distance between two blocking disks 11 is small, it will affect the rotation of the blocking disk 11, and if the distance between the two blocking disks 11 is too large, it will affect the interception of garbage. Therefore, the distance between two adjacent blocking disks 11 is set to half the diameter of the blocking disk 11. Such a setting can effectively intercept garbage and avoid mutual interference between adjacent blocking disks 11.

[0029] In one embodiment, the circumference of the blocking plate 11 is provided with a plurality of anti-slip grooves 111 arranged at intervals.

[0030] In this embodiment, in order to increase the friction force on the circumference of the blocking plate 11, a plurality of grooves are evenly arranged on the circumference of the blocking plate 11, so that an anti-slip structure is formed on the circumference of the blocking plate 11. Such a setting can increase the friction force between the blocking plate 11 and the garbage, which is beneficial for transporting the garbage to the recycling end.

When the two cable devices 21 are released at the same time, the blocking plates 11 can move upward under the action of their own buoyancy, so that they are always on the water surface. By simultaneously retracting and releasing the two cable devices 21, the movement of the cleaning device 1 in the vertical direction can be realized. When one of the cable devices 21 is retracted or not working and the other cable device 21 is released, it can drive the multiple blocking plates 11 to move toward the direction of the retracted or inoperative cable device 21, so that the cleaning device 1 moves to one side of the river channel 200 to avoid the ship, thereby facilitating the passage of the ship.

[0033] In one embodiment, the cable device 21 includes a first connecting member 211, an electric reel 212 and a cable 213.

The first connecting member 211 is rotatably installed in the mounting holes of the blocking plate 11 at both ends along the vertical direction, so that the first connecting member 211 and the blocking plate 11 can move relative to each other. The cable 213 connects the first connecting member 211 and the electric reel 212, and the electric reel 212 can retract and release the cable 213. Such an arrangement can drive the blocking plate 11 to move.

[0035] Furthermore, it also includes a second connecting member 13, which is rotatably installed in the installation holes of the remaining blocking plates 11 along the vertical direction. The connecting rope 12 connects two adjacent second connecting members 13 to prevent the connecting rope 12 from interfering with the rotation of the blocking plate 11.

[0036] The first connecting member 211 and the second connecting member 13 have the same structure.

[0037] In one embodiment, the river garbage cleaning system also includes a first detection device, a second detection device and a control device, the first detection device is used to detect ships on the river surface, the second detection device is used to detect the water level of the river 200, and the control device is electrically connected to the first detection device, the second detection device and the driving device 2, so as to control the driving device 2 to drive the cleaning device 1 to move along the width direction of the river 200 to one side of the river 200 according to the detection result of the first detection device, and to control the driving device 2 to drive the cleaning device 1 to move in the vertical direction according to the detection result of the second detection device to adapt to the water level of the river.

[0038] In this embodiment, in order to detect in real time whether there is a ship passing and detect changes in water level, a first detection device and a second detection device are further provided. The first detection device can be installed on both sides of the river channel 200, or on one of the blocking plates 11, so that the river surface conditions can be detected in real time through the first detection device. The second detection device can be installed on one of the blocking plates 11, or on one of the cable devices 21, so that the water level changes can be detected in real time through the second detection device. The first detection device and the second detection device can transmit the detection results to the control device, and the control device can control the operation of the driving device 2 according to the detection results, and then drive the cleaning device 1 to move through the driving device 2. Specifically, During use, when the first detection device detects that there is a ship on the river that needs to pass, the control device controls one of the cable devices 21 to retract and the other cable device 21 to release, so as to drive the multiple blocking plates 11 to move toward the retracted cable device 21, so that the cleaning device 1 moves to one side of the river 200 to avoid the ship. When the second detection device detects that the water level drops, the control device controls the two cable devices 21 to retract at the same time, so as to drive the multiple blocking plates 11 to move downward to adapt to the water level. When the second detection device detects that the water level rises, the control device controls the two cable devices 21 to release at the same time, so that the blocking plates 11 can move upward under the action of their own buoyancy, so that they are always on the water surface.

[0039] In this embodiment, the first detection device includes a radar detector, which is disposed on one side of the river channel 200 , and the second detection device includes a radar water level sensor, which is installed on the electric reel 212 .

[0040] It should be noted that the radar detector and the radar water level sensor are both existing technologies and will not be described in detail here.

[0041] In one embodiment, the control device determines the expansion and contraction range of the cable 213 according to the mathematical model 1 of the path planning of the cleaning device 1; the mathematical model 1 includes: in an ideal case, the water surface line of the river channel 200 is regarded as a straight line, and for the riverbed cross-sectional curve, through careful analysis, a three-variable linear equation is used to fit the riverbed cross-sectional curve , where a, b, c, and d are fitting coefficients, x is the distance from the starting point of the section, and y is the elevation of the section. The equation can be fitted with the measured data to obtain the mathematical model of the riverbed section curve for hydrological calculation and hydraulic analysis. Considering the maximum width of the riverbed section , and the point where the elevation reaches its maximum value at this width, introducing To indicate the horizontal position of the point from the starting point of the section, Represents the cross-sectional elevation of the point, which is calculated following the same three-variable linear equation: In the water surface garbage cleaning operation, the original length of the cable 213 between the cleaning device 1 and the electric reel 212 is calculated. Indicates the horizontal distance between the cleaning device 1 and the electric reel 212 in the vertical direction, combined with the maximum section elevation and maximum width of the riverbed , using the Pythagorean theorem, the calculation formula for the original telescopic length S of the cable 213 can be derived: Considering the need for ship navigation, when a ship passes, the length of the cable 213 must be adjusted to avoid collision. Assuming the width of the ship is B, the maximum extension of the cable 213 is It can be calculated by adding the original length S to the ship's width B, that is, =S+B. By fitting the riverbed cross-section curve through a three-variable linear equation and combining it with the actual needs of ship navigation, an accurate mathematical model was established to deduce the calculation method of the motor rope expansion and contraction amount and the motor range that needs to adjust the rope, providing technical support for surface garbage cleaning operations.

[0042] In one embodiment, the control device calculates the theoretical telescopic length change of the cable 213 according to the second mathematical model; the second mathematical model includes: A three-dimensional Cartesian coordinate system is established with the riverbed as the xoy plane, and the positive direction of the vertical axis points to the water surface; use the equation Indicates the riverbed cross-section curve; Measure the initial distance, and use the second detection device to detect the height of the cleaning device 1 from the river bottom and the distance between the electric reel 212 and the orthographic projection of the cleaning device 1 on the river bottom ; Calculate the initial length of cable 213: ; After monitoring the water level change, the new length is calculated.

At this time, the new length of the cable 213 is: ; Calculate the change in the telescopic length of the cable 213, Δs, Δs = ; The control device controls the driving device 2 to retract and release the cable 213 according to the calculated change in the telescopic length of the cable 213, so that the cleaning device 1 can continue to work normally at the new water level. The cable device 21 can retract and release the cable 213 according to the calculated change in the theoretical telescopic length of the cable 213, so that the blocking plate 11 of the river channel 200 can still remain in a straight line on the water surface, and can adapt to the change in water level to perform garbage cleaning work in the river channel 200 normally.

[0043] In one embodiment, the river garbage cleaning system further includes a solar power generation device 4, which is arranged beside the river 200 and is electrically connected to the driving device 2 and the recycling device 3.

The garbage at the recycling end can be transported to the garbage storage box 32 through the belt conveyor 31, which is convenient for recycling and processing.

[0045] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the present invention is described in detail: When in use, the garbage in the river channel 200 flows downward along the river. When the garbage contacts the blocking plate 11, it is intercepted by the blocking plate 11 and transported to the recycling end. The belt conveyor 31 transports the garbage to the garbage storage box 32, thereby completing the cleaning of the garbage in the river channel 200. When the water level of the river channel 200 changes, the second detection device detects the water level of the river channel 200 in real time and transmits it to the control device. The control device obtains the telescopic length of the cable 213 through a mathematical model based on the detected data, and controls the electric reel 21 The cable 213 is rotated to adjust the telescopic length so that the blocking plate 11 can adapt to the change of the water level and keep it in a straight line on the water surface. When a ship passes through the river channel 200, the first detection device detects the ship and transmits it to the control device. The control device controls the electric reel 212 to work so that the blocking plate 11 moves to one side of the river channel 200 along the set trajectory to ensure the smooth passage of the ship. After the ship passes, the control device controls the motor reel to work so that the blocking plate 11 returns to the initial position to continue intercepting garbage.

[0046] The present application utilizes the flow of water to drive the blocking disc 11 to rotate, thereby intercepting garbage on the water surface, which is environmentally friendly and energy-saving.

[0047] The present application can control the blocking plate 11 by rotating the electric reel 212 to change the extension length of the cable 213 when the water level changes, so that the blocking plate 11 adapts to the change of water level and is located on a straight line on the horizontal plane of the river channel 200.

[0048] When a ship is passing, the present application can use the path planning mathematical model of the barrier plate 11 to determine the extension and retraction range of the cable 213, and control the movement of the barrier plate 11 by controlling the rotation of the electric reel 212 to move it to the side of the river channel 200, thereby achieving automatic avoidance of the ship.

[0049] This application significantly improves the automation level and adaptability of the entire river garbage cleaning system, realizes the efficient and safe cleaning of 200% garbage in the river, and can solve the problems of high safety hazards, low automation level and poor adaptability of existing cleaning methods.

[0050] This application uses photovoltaic power generation to achieve efficient recycling of 200% of garbage in the river. The energy supply device uses solar energy to maximize the utilization of clean energy, with obvious energy-saving effects.
