[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] like Figures 1 to 4 As shown, a river channel waste cleaning system based on the adaptive principle includes a power system 1, a waste collecting device 2, a floating device, a lifting device, a cleaning structure 5 and a collecting component 6, wherein the power system 1 utilizes water flow to realize energy conversion, thereby providing energy for the river channel 100 waste cleaning system of the present application; the waste collecting device 2 is arranged on the river channel 100, and is used to collect pollutants floating on the surface of the river channel 100; the floating device is connected to the waste collecting device 2, and is used to provide buoyancy for the waste collecting device 2, so that the waste collecting device 2 can float on the water surface to collect waste; the lifting device is used to lift the waste collecting device 2, so as to facilitate the unloading of the pollutants collected on the waste collecting device 2 into the collecting component 6; the collecting component 6 is used to realize temporary storage of waste, thereby realizing regular automatic cleaning of the waste collecting device 2; the cleaning device is used to assist the intercepted pollutants on the waste collecting device 2 to move to the collecting component 6.

[0022] The power system 1 is arranged in the river channel 100, and includes a runner 11 and an energy center 12. The runner 11 includes a rotating shaft 111 and a plurality of blades 112 arranged along the length direction of the rotating shaft 111. When the water flows through the blades 112, it can drive the rotating shaft 111 to rotate, thereby converting the potential energy of the water flow into kinetic energy. Driving gears are arranged at both ends of the rotating shaft 111, and a first output gear, a second output gear and a third output gear are arranged on the circumference of the rotating shaft 111. The energy center 12 includes an inflator 121, an air pump 122, a generator 123, an energy storage battery 124 and a mobile clutch. Specifically, the first output gear is connected to the inflator 121, the second output gear is connected to the air pump 122, and the third output gear is connected to the generator 123. The mobile clutch can control the runner 11 to be connected to the inflator 121, the air pump 122, or the generator 123, thereby realizing the conversion of the energy supply equipment.

[0023] The runner 11 can be set underwater or on the water surface. The runner 11 is set at the depth of the river channel 100 with the fastest water flow rate according to the monitoring of the river flow rate. In one embodiment, if the floating objects on the surface of the river channel 100 are relatively fine, the power system 1 is set upstream of the waste collection device 2. At this time, the water flow that flushes the power system 1 is more turbulent, which can generate greater kinetic energy, and the pollutants are not easy to entangle and accumulate on the surface of the runner 11; if there are many floating pollutants on the surface of the river channel 100, the power system 1 is set downstream of the waste collection device 2. Then, when the pollutants are intercepted and removed by the waste collection device 2, the water flow flushes the power system 1 again to achieve production capacity. At this time, the energy recovery rate is low, but the pollutants are not easy to accumulate on the surface of the runner 11.

[0024] The waste collection device 2 is arranged on the river channel 100. When it is specifically arranged, the power system 1 can be arranged in a section where the water flow is relatively turbulent, and the waste collection device 2 can be arranged in a section where the water flow is relatively slow. The waste collection device 2 includes a collection plate 21, and a plurality of interception filters 22 are fixed at intervals on the surface of the collection plate 21. The extension direction of the interception filter 22 is consistent with the width of the river channel 100. The collection plate 21 is arranged obliquely, and the side of the collection plate 21 located downstream is higher than the side of the collection plate 21 located upstream, so that the interception filter 22 can be used to intercept pollutants. The height of the multiple interception filters 22 gradually increases toward the downstream direction, and the mesh on the interception filter 22 can be disassembled and replaced.

[0025] A guide wall 7 is cast on one side of the river channel 100. The floating device includes a floating airbag 3 arranged at the bottom of the waste collection device 2. A guide rail is fixed on the guide wall 7. The floating airbag 3 is slidably connected to the guide rail of the guide wall 7. The buoyancy of the floating airbag 3 is used to make the position of the waste collection device 2 change with the water level of the river channel 100. After the waste collection device 2 intercepts the waste, the weight change information of the waste collection device 2 is collected, and then the buoyancy of the floating airbag 3 is adjusted to keep the position of the waste collection device 2 in the water unchanged.

[0026] Specifically, a plurality of sub-chambers are formed in the floating airbag 3, and the plurality of sub-chambers are sequentially arranged along the width direction of the river channel 100. The sub-chambers include water chambers 31 and air chambers 32 that are sequentially staggered. The water chamber 31 is used to fill liquid, and the air chamber 32 is used to fill gas. The amount of water in the water chamber 31 changes with the amount of waste collected on the waste collection device 2. When the waste increases, the air chamber 32 is inflated and the water chamber 31 is drained; when the waste is transferred, the air chamber 32 is deflated and the water chamber 31 is filled with water. A drainage port 311 is provided in the area near the top of each water chamber 31, and a one-way valve is provided at the drainage port 311, so that water can only flow out of the water chamber 31 through the one-way valve; at the same time, a water inlet 312 is also provided at the bottom of each water chamber 31, and a one-way valve is also provided at the water inlet 312, so that only water can be absorbed at the water inlet 312 through the one-way valve. Each air cavity 32 is connected to an exhaust pipe 33 and an air filling pipe 34, through which the amount of gas filled in the air cavity 32 can be changed, thereby adjusting the buoyancy of the floating airbag 3. It should be noted that the partition layer between the water cavity 31 and the air cavity 32 is elastic, and when the air cavity 32 is inflated, the partition layer can be deformed and squeeze the water cavity 31, so that the water in the water cavity 31 can be discharged through the drain port 311. In addition, the floating airbag 3 is also provided with an interlayer for the exhaust pipe 33 and the air filling pipe 34 to pass through, thereby reducing the risk of the exhaust pipe 33 and the air filling pipe 34 being directly in contact with the water flow and being corroded or washed away.

[0027] The lifting device is arranged on the guide wall 7, and is used to lift one side of the waste collection device 2. When one side of the collection plate 21 is lifted by the lifting device, the heights of the collection plate 21 on both sides of the river channel 100 are inconsistent, thereby forming an inclined surface, so that the collected pollutants can slide unidirectionally along the interception filter 22. The lifting device includes a plurality of hydraulic push rods 4, one end of the hydraulic push rod 4 is connected to the guide wall 7, and the other end is rotatably connected to the surface of the collection plate 21, and the hydraulic push rod 4 is arranged above the collection plate 21, thereby completing the function of lifting the collection plate 21 and reducing the scouring of the lifting device by the water flow.

[0028] The collecting component 6 is arranged on one side of the river channel 100, and the collecting component 6 and the guide wall 7 are arranged on both sides of the river channel 100 respectively. When the lifting device drives the waste collecting device 2 to tilt, the pollutants collected on the waste collecting device 2 can be temporarily stored in the collecting component 6, so as to facilitate the maintenance personnel to uniformly recover them later. The collecting component 6 includes a collecting well 61 cast on one side of the collecting plate 21, and a pouring port 611 is opened on the side wall of the collecting well 61. One end of the collecting plate 21 is overlapped on the bottom wall of the pouring port 611. A blocking gate 62 is also arranged at the pouring port 611. The blocking gate 62 is in a state of closing the pouring port 611 in daily use. When the pollutants on the collecting plate 21 need to be dumped, the blocking gate 62 can rise upward, thereby realizing the opening of the pouring port 611.

[0029] The collecting well 61 is open at both ends, and a filter screen 63 is also provided in the collecting well 61. The filter screen 63 is provided below the pouring port 611. The pollutants can be collected above the filter screen 63 through the filter screen 63 for regular cleaning by maintenance personnel. The water flow can continue to flow into the river channel 100 after passing through the filter screen 63.

[0030] The cleaning structure 5 is used to push the pollutants on the interception filter 22 to move into the collection component 6, and includes a scraper 51, a driving rope 52 and a rope drive source. The driving rope 52 is connected to both sides of the scraper 51, and the end of the driving rope 52 away from the scraper 51 is connected to the rope drive source, so that the scraper 51 can be driven to move back and forth along the interception filter 22 under the pull of the driving rope 52, so as to achieve the scraping and resetting of the pollutants by the scraper 51. It should be noted that the interception filter 22 includes a plurality of transverse ribs 221 arranged at intervals, and the transverse ribs 221 on two adjacent interception filters 22 are staggered in the height direction.

[0031] The present application also discloses a river channel waste cleaning control system based on an adaptive principle. The control system is the hub center of the river channel waste cleaning system of the present application. The central controller is electrically connected to each component to collect real-time data of the system operation, conduct a comprehensive analysis, and output instructions in a timely manner as required to control the operation of each component and ensure that the system of the present application collects waste smoothly and orderly.

[0032] The rotating shaft 111 is controlled to mesh with different output gears through a mobile clutch, and then connected to different devices accordingly. The specific design logic is: when the vacuum pump 122 is working, the vacuum pump 122 is meshed with the rotating shaft 111; when the inflator 121 is working, the inflator 121 is meshed with the rotating shaft 111; when both are not working, the rotating shaft 111 is meshed with the generator 123, thereby realizing the charging of the battery. When the battery power is fully charged, the rotating shaft 111 is idling and is not connected to any device.

[0033] The floating airbag 3 is provided with a liquid level sensor for monitoring and obtaining the real-time submerged depth of the floating airbag 3; the standard submerged depth is set in the central controller. When the real-time submerged depth is greater than the standard submerged depth, the inflator 121 works to evenly inflate each air cavity 32. At this time, the water cavity 31 is compressed, so that the water in the water cavity 31 is discharged from the drain port 311, thereby increasing the buoyancy of the floating airbag 3 and making the submerged depth reach the standard submerged depth. Similarly, when the real-time submerged depth is less than the standard submerged depth, the air pump 122 can be used to extract the gas in the air cavity 32, thereby forming a negative pressure in the water cavity 31, so that the water in the river can be sucked into the water cavity 31 through the water inlet 312, increasing the weight of the floating airbag 3, and deepening the submerged depth. The design of the floating airbag 3 enables the river channel sewage cleaning system based on the adaptive principle of the present application to adaptively adjust its position as the water level changes, thereby making the draft of the floating airbag 3 unchanged, and can be stably set on the water surface without being affected by the rise and fall of the water level.

[0034] The battery is electrically connected to the inflator 121, the vacuum pump 122, the lifting device, and the cleaning device at the same time, thereby achieving the effect of peak regulation and gap filling; if the lifting device and the cleaning device are directly connected to the wheel 11, the energy supply is unstable and it is difficult to meet the operating requirements of the lifting device and the cleaning device; the battery is connected to the inflator 121 and the vacuum pump 122 at the same time. When the kinetic energy formed by the real-time water flow potential energy conversion is difficult to meet the operating requirements of the inflator 121 and the vacuum pump 122, the energy storage in the battery can be used to perform functions synchronously to achieve rapid adjustment of the sinking depth of the floating airbag 3.

[0035] The river channel waste cleaning system based on the adaptive principle of the present invention can realize river channel waste cleaning through the cooperation between various systems. At the same time, the control system can obtain the operating conditions during the working process according to the working conditions and equipment parameters of the equipment, and through calculation and analysis, it can realize real-time control and fully automatic adjustable waste cleaning of the whole system, thereby solving the problem of cleaning floating waste in the river channel, as well as the problems of safety and workload in the waste cleaning process, and can also solve the problem of changes in the load demand of the cleaning device due to changes in the water flow rate and the amount of waste after seasonal changes.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
