Description

Technical Field

[0001] This invention relates to a water body garbage cleaning device, and more particularly to an automatic garbage cleaning system applied to rivers. Background Technology

[0002] Human activities constantly generate various types of waste, some of which ends up in rivers for various reasons. River waste is mainly divided into floating debris and sedimentary debris. Floating debris is mostly composed of plastic and wood products, with plastic products posing a greater threat to the ecosystem and being extremely difficult to decompose. Therefore, to reduce the harm of floating debris to river ecosystems, sanitation departments arrange for specific personnel to regularly retrieve floating objects from rivers, lakes, and other waterways. However, this method is inefficient and labor-intensive, resulting in minimal effectiveness. Summary of the Invention

[0003] This invention provides an automatic garbage cleaning system for river channels, solving the problem of difficulty in salvaging floating objects in existing technologies.

[0004] The above-mentioned technical problems of the present invention are mainly solved by the following technical solution: an automatic garbage cleaning system for river channels, comprising: a garbage collection component, consisting of positioning bases fixed on both sides of the river channel, several steel cables fixedly connected in parallel between the two positioning bases, a frame movably sleeved on the steel cables, a flexible floating rope fixedly connected between two adjacent frames, a width-limiting rope fixedly connected between two adjacent frames, and a winding rope, wherein the flexible floating rope, the width-limiting rope, and the winding rope are all non-elastic ropes with a low elongation coefficient, the steel cables, the frame, the width-limiting rope, and the winding rope are all located below the water surface, the single length of the width-limiting rope is shorter than the single length of the flexible floating rope, a guide wheel is provided on each of the two positioning bases, the winding rope is connected end to end and simultaneously sleeved on the two guide wheels, and a winding motor is also provided on one of the positioning bases and drivenly connected to the corresponding guide wheel, and the winding rope is fixedly connected to one end of the frame.

[0005] The positioning base in this invention is used to fix the steel cables. Its structure can be cast concrete or steel structure, fixed to both sides of the river channel, ensuring that several steel cables are firmly fixed below the water surface. The taut steel cables serve as the carrier of the frame, allowing the frame to be relatively stably maintained in the flowing water. The frames are connected by a width-limiting rope. Simultaneously, one end of the frame is also connected to the positioning base by a width-limiting rope, while the other end of the frame is connected to a winding rope. A winding motor can drive the winding rope to run in both directions. Therefore, during the net-laying process, the winding rope can pull the frame to move towards the opposite bank of the river. With the help of the wide rope, the connected frames will be fully stretched and distributed at equal intervals. At this time, the flexible floating ropes between the frames will also unfold, forming a continuous "W" shape across the river. The floating flexible ropes can block floating objects and reduce the flow of floating objects downstream. When the flexible floating ropes capture too many floating objects, the invention can start the net-hauling process. The winding rope can pull the frame to move in the opposite direction, so that the frame will push the other frames along the way to move together. Finally, all the frames are pulled to one side of the riverbank. The flexible floating ropes can also pull the captured floating objects to the bank, making it easy for manual retrieval.

[0006] Furthermore, the present invention also includes two sets of lifting assemblies, each mounted on the positioning base. Each lifting assembly includes a lifting motor, a reduction gearbox, a guide groove vertically mounted on the positioning base, a lead screw vertically rotatably mounted within the guide groove, and a lifting seat slidably mounted within the guide groove. The steel cable is fixedly connected to the lifting seat, and the guide wheel and the winding motor are also mounted on the lifting seat. The two lifting assemblies operate synchronously to control the lifting of the two lifting seats, thus controlling the height of the steel cable. The significance of this design lies in the fact that the water level in the river is not stable, and the steel cable must remain below the water surface; otherwise, the invention would fail. Therefore, two sets of lifting assemblies are needed to control the real-time height of the steel cable to adapt to the constantly changing river water level and ensure the invention does not fail.

[0007] Furthermore, the present invention also includes a power supply, a water level sensor, and a controller, wherein the controller is connected to the lifting motor and the winding motor. The power supply can be AC ​​power or solar power to power the controller. The controller is electrically connected to the water level sensor, the lifting motor, and the winding motor. The water level sensor can periodically detect the water level and send the detection data to the controller. The controller adjusts the two lifting motors according to the real-time water level, thus enabling the present invention to have a fully autonomous real-time control function for the height of the steel cable. Simultaneously, the controller can also control the winding motor periodically or remotely. For example, during the flood season, the controller can implement a specific protective program, at which time the steel cable height will be raised to its maximum, and the garbage collection component will also be in the net-closing state to minimize contact with floodwaters and prevent damage to the present invention.

[0008] Furthermore, the present invention also includes a waste collection pool located on the downstream side of a positioning base. The waste collection pool has an opening facing upstream and can temporarily collect floating debris collected by the waste collection assembly. The waste collection pool can be constructed from a floating platform or a brick-concrete structure. The waste collected by the waste collection assembly can be quickly transferred to the waste collection pool temporarily, allowing the waste collection assembly to be returned to its original position as soon as possible, thus improving the efficiency of cleaning up river debris.

[0009] Furthermore, the flexible floating line is equipped with several floats and blocking elements connected in series. The blocking elements are located between adjacent floats and are mainly snowflake-shaped. The floats are used to generate buoyancy, while the blocking elements are used to block floating objects on the water surface, thereby improving the flexible floating line's ability to capture floating objects.

[0010] Therefore, this invention has the following characteristics compared to the prior art: 1. This invention changes the state of the flexible floating rope by controlling the spacing of the frames on the steel cable. When the flexible floating rope is in the unfolded state across the river surface, floating objects on the water surface will be captured by the flexible floating rope. When this invention performs the net-hauling procedure, the flexible floating rope will be pulled to the riverbank, and the captured garbage will also be brought to the bank, making it easier to salvage and clean up, and achieving a better garbage cleaning effect; 2. The water level is detected by a water level sensor, and two sets of lifting components are used to control the real-time height of the steel cable to adapt to the ever-changing river water level and ensure that this invention will not fail.

[0018] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Example 1: See Figure 1 , Figure 2 and Figure 3 An automatic garbage collection system for river channels includes: a garbage collection component 100, comprising positioning bases 110 fixed on both sides of the river channel, four parallel steel cables 120 fixedly connected between the two positioning bases, a frame 130 movably sleeved on the steel cables, a flexible floating rope 140 fixedly connected between two adjacent frames, a width-limiting rope 150 fixedly connected between two adjacent frames, and a winding rope 160. The flexible floating rope, width-limiting rope, and winding rope are all non-elastic ropes with low elongation coefficients. The steel cables, frames, width-limiting rope, and winding rope are all located below the water surface. The single length of the width-limiting rope is shorter than the single length of the flexible floating rope. Each of the two positioning bases is provided with a guide wheel 170. The winding rope is connected end to end and simultaneously sleeved on the two guide wheels. One of the positioning bases is also provided with a winding motor 180 that is driven and connected to the corresponding guide wheel. A drive shaft 190 is connected between the winding motor and the guide wheel. The winding rope is fixedly connected to one end of the frame.

[0021] In this embodiment, the positioning base is used to fix the steel cables. Its structure is a cast-in-place concrete structure, fixed to both sides of the river channel to ensure that the four steel cables are firmly fixed below the water surface. The taut steel cables serve as the carrier of the frame, allowing the frame to remain relatively stable in the flowing water. The frames are connected by width-limiting ropes. One end of the frame is also connected to the positioning base by a width-limiting rope, while the other end of the frame is connected to a winding rope. A winding motor can drive the winding rope to move forward and backward. Therefore, during the net-laying process in this embodiment, the winding rope can pull the frame towards the opposite bank of the river. Under the action of the system, the connected frames will be fully opened and distributed at equal intervals. At this time, the flexible floating ropes between the frames will also unfold, forming a continuous "W" shape that spans the river. The floating flexible ropes can block floating objects and reduce the flow of floating objects downstream. When the flexible floating ropes capture too many floating objects, this embodiment can carry out the net-hauling procedure. The winding rope can pull the frame to move in the opposite direction, so that the frame will push the other frames along the way to move together. Finally, all the frames are pulled to one side of the riverbank. The flexible floating ropes can pull the captured floating objects to the bank together, making it convenient for manual retrieval.

[0022] See Figure 1 and Figure 5 This embodiment also includes two lifting assemblies 200. Each lifting assembly is mounted on a positioning base and includes a lifting motor 210, a reduction gearbox 220, a guide groove 230 vertically mounted on the positioning base, a lead screw 240 vertically rotatably mounted within the guide groove, and a lifting seat 250 slidably mounted within the guide groove. The lifting seat 250 contains a lead screw nut that mates with the lead screw. The steel cable is fixedly connected to the lifting seat, and the guide wheel and winding motor are also mounted on the lifting seat. The two lifting assemblies operate synchronously to control the lifting of the two lifting seats, thus controlling the height of the steel cable. The significance of this design lies in the fact that the water level in the river is not stable, and the steel cable must be kept below the water surface; otherwise, this embodiment would fail. Therefore, two lifting assemblies are needed to control the real-time height of the steel cable to adapt to the constantly changing river water level and ensure that this embodiment does not fail.

[0023] See Figure 1 and Figure 7 This embodiment also includes a power supply, a water level sensor 300, and a controller. The controller is connected to the lifting motor and the winding motor. The power supply can be AC ​​power or solar power to power the controller. The controller is electrically connected to the water level sensor, lifting motor, and winding motor. The water level sensor periodically detects the water level and sends the data to the controller. The controller adjusts the two lifting motors according to the real-time water level, thus enabling this embodiment to autonomously control the height of the steel cable in real time. The controller can also periodically or remotely control the winding motor. For example, during flood season, the controller can implement specific protective procedures, raising the steel cable to its maximum height and engaging the garbage collection component to minimize contact with floodwaters and prevent damage to this embodiment.

[0024] See Figure 2 This embodiment also includes a waste collection pool 400 located on the downstream side of a positioning base. The waste collection pool has an opening facing upstream and can temporarily collect floating debris collected by the waste collection components. The waste collection pool can be constructed from a floating platform or a brick-concrete structure. The waste collected by the waste collection components can be quickly transferred to the waste collection pool temporarily, allowing the waste collection components to be returned to their original positions as soon as possible, thus improving the efficiency of cleaning up river waste.

[0025] See Figure 2 The length of a single width-limiting rope is between 3 and 6 meters, while the length of a single flexible floating rope is 1.5 to 2.5 times that of the width-limiting rope.

[0026] See Figure 4 and Figure 6The flexible floating line is equipped with several floats 141 connected in series and blocking elements 142. The blocking elements are located between adjacent floats and are mainly snowflake-shaped. The floats are used to generate buoyancy, while the blocking elements are used to block floating objects on the water surface, thereby improving the flexible floating line's ability to capture floating objects.

[0027] See Figure 4 The frame is a rectangular structure, and there are intersecting connecting rods 131 inside. There are four sleeve holes 132 at the four vertices of the frame for connecting with four steel cables. There is also a central sleeve hole 133 in the middle of the connecting rod for threading or fixing the winding rope. The frame is also provided with a vertically upward extension rod 134. The top of the extension rod is provided with a rope hole 135 for tying the flexible floating rope.

[0028] It will be apparent to those skilled in the art that the present invention can be modified in various ways, and such modifications are not considered to depart from the scope of the invention. All such modifications that are obvious to those skilled in the art are included within the scope of the claims.
