Description

Technical Field

[0001] This invention belongs to the technical field of river management, and specifically relates to an adaptive river debris cleaning system and control system. Background Technology

[0002] With the expansion of agricultural production, a large amount of domestic and industrial waste is discharged into waterways, causing a surge in floating debris. Traditional waterway cleaning methods rely heavily on manual dredging, which is not only inefficient and labor-intensive but also poses numerous safety hazards, such as the risk of sanitation workers falling into the water.

[0003] Meanwhile, the flow velocity of river channels is significantly affected by the seasons. During the rainy season, the flow velocity is fast and the amount of sewage increases sharply; during the dry season, the flow velocity slows down and sewage accumulates. Conventional cleaning equipment is difficult to adapt flexibly to different working conditions, and often experiences overload or underutilization, failing to meet the needs of efficient, safe and intelligent cleaning. Summary of the Invention

[0004] This invention provides an adaptive river debris cleaning system and control system to solve the problem of low river cleaning efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] On the one hand, this application provides an adaptive river debris cleaning system, comprising:

[0007] The power system, located on the river, includes a rotor and an energy center. The water flow washes the rotor to rotate and converts the water potential energy into energy, which is then transmitted to the energy center.

[0008] A waste collection device, installed on a river, includes a collection plate and an intercepting filter screen installed on the collection plate, the intercepting filter screen being used to intercept pollutants in the river.

[0009] A floating device is disposed below the waste collection device to provide buoyancy for the waste collection device to float on the water surface;

[0010] The lifting device includes one or more hydraulic telescopic rods, which are disposed on one side of the waste collection device for lifting the collection plate to an inclined position on one side.

[0011] A collection component, located on the side of the waste collection device away from the lifting device, includes a collection well, the collection plate being tilted to pour contaminants from the intercepting filter screen into the collection well.

[0012] Furthermore, the floating device includes a floating airbag, which is divided into several water chambers and several air chambers in a staggered manner along the width of the river channel. The air chambers are connected to an exhaust pipe and an inflation pipe. The top of the water chamber is provided with a drain outlet, and the bottom of the water chamber is provided with a water inlet. Both the water inlet and the drain outlet are provided with a one-way valve.

[0013] Furthermore, the intercepting filter screen is provided with multiple intervals, and the height of the intercepting filter screen gradually increases in the direction of downstream of the river channel.

[0014] Furthermore, the intercepting filter includes a number of spaced transverse ribs, and the transverse ribs on two adjacent intercepting filters are staggered in the height direction.

[0015] Furthermore, the collection plate is also provided with a cleaning structure, which includes a scraper and multiple drive ropes. Both sides of the scraper are connected to drive ropes, and the end of each drive rope away from the scraper is connected to a rope winding drive source. The scraper moves back and forth along the interception filter.

[0016] Furthermore, a guide wall is cast on one side of the waste collection device where the lifting device is located. One end of the hydraulic telescopic rod is connected to the guide wall, and the other end is rotatably connected to the surface of the collection plate.

[0017] The floating airbag is slidably connected to the guide wall and slides down along the guide wall.

[0018] Furthermore, the side wall of the collection well is provided with a pouring opening, and the end of the collection plate overlaps the bottom wall of the pouring opening;

[0019] The dumping port is equipped with a blocking gate that can close or open the dumping port.

[0020] Furthermore, the collection well has openings at both ends, and a filter screen is installed inside the collection well. The filter screen is located below the pouring port and is used to load and filter the pollutants collected by the waste collection device.

[0021] Furthermore, the energy center includes an air inflator, an air pump, a generator, and an energy storage battery. The air inflator, air pump, and generator are all connected to the power system. The electrical energy generated by the generator is stored in the energy storage battery. The energy storage battery is also connected to the air inflator, air pump, hydraulic telescopic rod, and rope drive source to provide power.

[0022] On the other hand, this application provides an adaptive river debris cleaning control system, including a central controller with a standard submersion depth; the floating airbag is equipped with a liquid level sensor for real-time measurement of the submersion depth of the floating airbag, and the liquid level sensor is capable of measuring the real-time liquid level depth.

[0023] When the real-time submersion depth is greater than the standard submersion depth, the central controller controls the air pump to work and evenly inflate each air chamber.

[0024] When the real-time submersion depth is less than the standard submersion depth, the central controller controls the air pump to work, and evenly extracts the gas from each air chamber.

[0025] The present invention can achieve the following beneficial effects:

[0026] 1. This application, by setting up a power system, can convert the potential energy generated by the water flow into energy stored in the energy center, thereby powering the cleaning system of this application. The waste collection device can intercept pollutants on the river, thereby realizing the automatic retrieval of pollutants. The floating device can stably float the waste collection device on the river surface, so that the waste collection device can adaptively adjust its position with the rise and fall of the water level. The lifting device and collection components can automatically concentrate and pile up the pollutants collected by the waste collection device, which is convenient for subsequent cleaning by staff.

[0027] 2. By forming several air chambers and water chambers inside the floating airbag, the inflation and deflation of the air chambers are achieved using inflation and deflation pipes, which in turn drives the discharge and intake of liquid in the water chambers, thereby adjusting the buoyancy of the floating airbag to achieve adaptive adjustment of the floating airbag.

[0028] 3. The cleaning structure can scrape off the pollutants on the filter screen, thereby assisting in cleaning the filter screen and enabling the pollutants collected on the filter screen to be collected into the collection well as much as possible, thus achieving self-cleaning of the filter screen.

[0036] 100. River channel. Detailed Implementation

[0037] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0038] like Figures 1 to 4 As shown, an adaptive river waste cleaning system includes a power system 1, a waste collection device 2, a floating device, a lifting device, a cleaning structure, and a collection component 6. The power system 1 utilizes water flow to convert energy and power the river 100 waste cleaning system of this application. The waste collection device 2 is installed on the river 100 to collect pollutants floating on the surface of the river 100. The floating device is connected to the waste collection device 2 to provide buoyancy, enabling the waste collection device 2 to float on the water surface for waste collection. The lifting device is used to lift the waste collection device 2, facilitating the unloading of the collected pollutants into the collection component 6. The collection component 6 is used for temporary storage of waste, thereby enabling the periodic automatic cleaning of the waste collection device 2. The cleaning device assists in moving the intercepted pollutants on the waste collection device 2 into the collection component 6.

[0039] The power system 1 is located within the river channel 100 and includes a rotor 11 and an energy center 12. The rotor 11 includes a shaft 111 and several blades 112 arranged along the length of the shaft 111. When water flows over the blades 112, it drives the shaft 111 to rotate, thereby converting the potential energy of the water flow into kinetic energy. Drive gears are provided at both ends of the shaft 111, and a first output gear, a second output gear, and a third output gear are arranged around the shaft 111. The energy center 12 includes an air pump 121, an air extractor 122, a generator 123, an energy storage battery 124, and a movable clutch. Specifically, the first output gear is connected to the air pump 121, the second output gear is connected to the air extractor 122, and the third output gear is connected to the generator 123. The movable clutch allows control of the rotor 11 to connect to the air pump 121, the air extractor 122, or the generator 123, thereby enabling the switching of energy supply equipment.

[0040] The impeller 11 can be installed underwater or on the water surface. The impeller 11 is positioned at the depth of the river channel 100 where the current is strongest, based on monitoring the river's flow velocity. In one embodiment, if the floating debris on the surface of the river channel 100 is relatively fine, the power system 1 is positioned upstream of the waste collection device 2. In this case, the water flow scouring the power system 1 is more turbulent, generating greater kinetic energy, and pollutants are less likely to entangle and accumulate on the surface of the impeller 11. If there are more floating pollutants on the surface of the river channel 100, the power system 1 is positioned downstream of the waste collection device 2. After the pollutants are intercepted and removed by the waste collection device 2, the water flow then scours the power system 1 to achieve energy production. In this case, the energy recovery rate is lower, but pollutants are less likely to accumulate on the surface of the impeller 11.

[0041] The waste collection device 2 is installed on the river channel 100. Specifically, the power system 1 can be installed in a section with relatively rapid water flow, while the waste collection device 2 can be installed in a section with relatively slow water flow. The waste collection device 2 includes a collection plate 21, on which multiple intercepting filter screens 22 are fixed at intervals. The extension direction of the intercepting filter screens 22 is consistent with the width of the river channel 100. The collection plate 21 is inclined, with the downstream side higher than the upstream side, thus enabling the intercepting filter screens 22 to intercept pollutants. The height of the multiple intercepting filter screens 22 gradually increases towards the downstream direction, and the mesh panels on the intercepting filter screens 22 can be disassembled and replaced.

[0042] A guide wall 7 is cast along one side of the river channel 100. The floating device includes a floating airbag 3 installed at the bottom of the waste collection device 2. A guide rail is fixed to the guide wall 7, and the floating airbag 3 is slidably connected to the guide rail of the guide wall 7. The buoyancy of the floating airbag 3 allows the position of the waste collection device 2 to change with the water level of the river channel 100. After the waste collection device 2 intercepts 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 constant.

[0043] Specifically, the floating airbag 3 contains several sub-chambers arranged sequentially along the width of the river channel 100. These sub-chambers include alternating water chambers 31 and air chambers 32. Water chambers 31 are filled with liquid, and air chambers 32 are filled with gas. The amount of water in the water chamber 31 varies depending on the amount of waste collected by the waste collection device 2. When waste increases, air chamber 32 is inflated, and water chamber 31 is drained; when waste is transferred, air chamber 32 is deflated, and water chamber 31 is filled with water. Each water chamber 31 has a drain outlet 311 near the top, equipped with a one-way valve to ensure that water can only flow out of the water chamber 31. Simultaneously, each water chamber 31 has an inlet 312 at its bottom, also equipped with a one-way valve to ensure that water can only be drawn in through the inlet 312. Each air chamber 32 is connected to an exhaust pipe 33 and an inflation pipe 34. The amount of gas filling the air chamber 32 is varied via the exhaust pipe 33 and the inflation pipe 34, thereby adjusting the buoyancy of the floating airbag 3. It should be noted that the partition layer between the water chamber 31 and the air chamber 32 is elastic. When air is inflated into the air chamber 32, the partition layer deforms, compressing the water chamber 31 and allowing water to drain out through the drain outlet 311. Furthermore, the floating airbag 3 is also provided with an interlayer for the exhaust pipe 33 and the inflation pipe 34 to pass through, thereby reducing the risk of direct contact between the exhaust pipe 33 and the inflation pipe 34 and the water flow, and thus the risk of corrosion or erosion.

[0044] A lifting device is installed on the guide wall 7 to lift one side of the waste collection device 2. After one side of the collection plate 21 is lifted by the lifting device, the height of the collection plate 21 on both sides of the river channel 100 is inconsistent, thus forming an inclined surface, allowing the collected pollutants to slide unidirectionally along the intercepting filter screen 22. The lifting device includes multiple 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. The hydraulic push rod 4 is positioned above the collection plate 21, thereby reducing the scouring of the lifting device by the water flow while completing the lifting function of the collection plate 21.

[0045] The collection component 6 is located on one side of the river channel 100, and the collection component 6 and the guide wall 7 are respectively located on both sides of the river channel 100. When the lifting device drives the sewage collection device 2 to tilt, the pollutants collected on the sewage collection device 2 can be temporarily stored in the collection component 6 for easy collection by maintenance personnel. The collection component 6 includes a collection well 61 cast on one side of the collection plate 21. The side wall of the collection well 61 has a pouring opening 611. One end of the collection plate 21 is attached to the bottom wall of the pouring opening 611. A blocking gate 62 is also provided at the pouring opening 611. The blocking gate 62 is in a closed state when in normal use. When it is necessary to pour out the pollutants on the collection plate 21, the blocking gate 62 can rise upward, thereby opening the pouring opening 611.

[0046] The collection well 61 has openings at both ends, and a filter screen 63 is installed inside the collection well 61. The filter screen 63 is located below the pouring port 611. The filter screen 63 allows pollutants to be collected above the filter screen 63 for maintenance personnel to clean regularly. Water can flow through the filter screen 63 and then continue to flow into the river channel 100.

[0047] The cleaning structure, used to move contaminants on the intercepting filter 22 into the collecting component 6, includes a scraper 51, a drive rope 52, and a rope winding drive source. Drive ropes 52 are connected to both sides of the scraper 51, and the ends of the drive ropes 52 furthest from the scraper 51 are connected to the rope winding drive source. This allows the scraper 51 to reciprocate along the intercepting filter 22 under the pull of the drive ropes 52, thus scraping and resetting the contaminants. It should be noted that the intercepting filter 22 includes several spaced transverse ribs 221, and the transverse ribs 221 on adjacent intercepting filter 22s are staggered in the height direction.

[0048] This application also discloses an adaptive river waste cleaning control system. The control system is the hub of the river waste cleaning system of this application. It uses a central controller to be electrically connected to each component, collects real-time data of system operation, performs comprehensive analysis, and outputs instructions in a timely manner as needed to control the operation of each component and ensure that the system of this application can collect waste smoothly and orderly.

[0049] The rotating shaft 111 is controlled by a movable clutch to engage with different output gears, thereby connecting to different devices. Specifically, the design logic is as follows: when the vacuum pump 122 is working, it engages with the rotating shaft 111; when the air compressor 121 is working, it engages with the rotating shaft 111; when neither is working, the rotating shaft 111 engages with the generator 123, thereby charging the battery. Once the battery is fully charged, the rotating shaft 111 idles and is not connected to any device.

[0050] A liquid level sensor is installed on the floating airbag 3 to monitor and obtain the real-time submersion depth of the floating airbag 3. A standard submersion depth is set in the central controller. When the real-time submersion depth is greater than the standard submersion depth, the inflator 121 operates, uniformly inflating each air chamber 32. At this time, the water chamber 31 is compressed, causing the water in the water chamber 31 to be discharged from the drain outlet 311, thereby increasing the buoyancy of the floating airbag 3 and allowing the submersion depth to reach the standard submersion depth. Similarly, when the real-time submersion depth is less than the standard submersion depth, the air extractor 122 can be used to extract the gas from the air chamber 32, thereby creating a negative pressure in the water chamber 31. This allows water in the river to be drawn into the water chamber 31 through the inlet 312, increasing the weight of the floating airbag 3 and deepening the submersion depth. The design of the floating airbag 3 enables the adaptive river debris cleaning system of this application to adaptively adjust its position according to changes in water level, thus ensuring that the draft of the floating airbag 3 remains constant and that it can be stably positioned on the water surface, unaffected by fluctuations in water level.

[0051] The battery is electrically connected to the air pump 121, the vacuum pump 122, the lifting device, and the cleaning device, thereby achieving peak shaving and power replenishment. If the lifting device and the cleaning device are directly connected to the wheel 11, the power supply will be unstable and it will be difficult to meet the operating requirements of the lifting device and the cleaning device. At the same time, the battery is connected to the air pump 121 and the vacuum pump 122. When the kinetic energy generated by the real-time water flow potential energy conversion is insufficient to meet the operating requirements of the air pump 121 and the vacuum pump 122, the energy stored in the battery can be used to perform the function synchronously, so as to achieve rapid adjustment of the sinking depth of the floating airbag 3.

[0052] This invention discloses an adaptive river debris cleaning system that achieves river debris cleaning through the cooperation of various systems. At the same time, the control system can obtain the operating conditions during the working process based on the working conditions and parameters of the equipment. Through calculation and analysis, it can control the entire system in real time and perform fully automatic and adjustable debris cleaning. This solves the problem of cleaning floating debris in the river, as well as the safety and workload issues in the debris cleaning process. It also solves the problem of changing load requirements of the cleaning device due to changes in water flow velocity and seasonal changes in the amount of debris.

[0053] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
