Description

Technical Field

[0001] This invention belongs to the field of pond and lake waste recycling technology, and specifically relates to a pond and lake waste recycling device. Background Technology

[0002] Currently, waste collection devices for ponds, lakes, and other bodies of water typically employ floating mobile platforms. The collection mechanism is rigidly mounted to the hull, and its working posture and angle are fixed parameters determined during the manufacturing stage. In actual operation, the collection mechanism maintains this preset fixed posture, using a propulsion system to collect floating waste. This type of device has a relatively simple structure, low manufacturing cost, and can complete basic waste collection operations under standard water level conditions.

[0003] However, in practical applications, the water levels of ponds and lakes fluctuate significantly due to seasonal rainfall, evaporation, climate change, and human intervention. Because existing collection mechanisms employ a fixed-posture design, they cannot adjust their working angle and posture accordingly when water levels change, leading to a substantial decrease in collection efficiency. Specifically, when the water level is low, the fixed-posture collection mechanism does not make sufficient contact with the water surface, limiting the collection range; when the water level is high, the collection mechanism is prone to rigid collisions with obstacles in the water (such as aquatic plants, driftwood, fishing nets, etc.), causing equipment damage or jamming. Furthermore, the fixed-posture design prevents the collection mechanism from optimizing its posture based on real-time water level conditions, making it impossible to maintain optimal collection performance and safety under different water level environments. Current technology lacks a solution that can automatically adjust the posture of the collection mechanism according to water level changes and possess intelligent obstacle avoidance capabilities. Summary of the Invention

[0004] To address the problem that existing waste recycling devices have a fixed collection mechanism and cannot automatically adjust their working angle and posture according to changes in water level, this invention provides a waste recycling device for ponds and lakes.

[0005] The objective of this invention can be achieved through the following technical solutions: A pond / lake waste recycling device includes a mobile platform, an adaptive adjustment component and a collection component mounted on the mobile platform. The adaptive adjustment component includes a support portion, a connecting rod portion, a swing avoidance portion, a cam rotation portion and a sliding portion mounted on the mobile platform. The collection component is mounted on the swing avoidance portion. A floating component is externally connected to the sliding portion. One end of the connecting rod portion is hinged to the center of the swing avoidance portion, and the other end of the connecting rod portion is slidably connected to the support portion. Both the cam rotation portion and the sliding portion are mounted on the support portion. The sliding portion is driven by the cam rotation portion and the cam rotation portion. The cam rotation portion is driven by the swing avoidance portion. The sliding portion drives the cam rotation portion to rotate in response to water level changes. The cam rotation portion drives the swing avoidance portion to intermittently swing back and forth relative to the hinge point of the connecting rod portion.

[0006] As a further embodiment of the present invention, the cam rotating part includes a rotating block and a protrusion disposed on the rotating block. The rotating block is provided with an arc-shaped groove and a vertical groove, and the vertical groove communicates with the arc-shaped groove to form a guide groove.

[0007] As a further embodiment of the present invention, the sliding part includes a limiting seat, a slider and a first spring. The limiting seat is fixed on the support part and has a vertical groove. The slider is slidably disposed in the groove. The two ends of the first spring are respectively connected to the slider and the bottom of the groove. A guide rod is provided on the slider and the guide rod extends into the guide groove formed by the vertical groove and the arc groove.

[0008] As a further embodiment of the present invention, guide blocks are respectively provided on both sides of the hinge point between the swing avoidance part and the connecting rod part, and the protrusion intermittently contacts one of the guide blocks to drive the swing avoidance part to swing relative to the hinge point.

[0009] As a further aspect of the present invention, the protruding triangular structure has arc-shaped edges.

[0010] As a further embodiment of the present invention, the connecting rod includes a first connecting rod, a second connecting rod, and a third connecting rod. The two ends of the second connecting rod are respectively hinged to one end of the first connecting rod and one end of the third connecting rod. The other end of the third connecting rod is slidably mounted on the support via a guide rail, and the other end of the third connecting rod is connected to the bottom wall of the guide rail via a second spring. The other end of the first connecting rod is hinged to the swing avoidance part.

[0011] As a further aspect of the present invention, the support portions on both sides of the first connecting rod are provided with limiting rods for restricting the range of motion of the first connecting rod.

[0012] As a further embodiment of the present invention, the swing avoidance part includes a central connecting block and a swing arm disposed on the central connecting block. The central connecting block is hinged to the other end of the first connecting rod, and the angle between the swing arm and the horizontal plane is adjusted within the range of 15°-20° when the water level changes.

[0013] As a further embodiment of the present invention, the rotating block is rotatably mounted on the support, and an arc-shaped groove is provided every 180° along the circumferential direction of the rotating block, with adjacent arc-shaped grooves connected by a vertical groove.

[0014] As a further embodiment of the present invention, the collecting component is disposed at the end of the swing arm, and the collecting component is a collecting net or a collecting plate.

[0015] The beneficial effects of this invention are: This device senses water level changes through floating components, triggering a mechanical linkage mechanism to construct a closed-loop regulation system based on dynamic water level feedback. The mobile platform serves as the basic carrier, and a spatial constraint framework is constructed through the support section, forming a deformable four-bar linkage between the connecting rod and the swing-avoidance section. The design of the floating component connected to the sliding section converts water level changes into vertical displacement. The cooperation between the slider and the guide rod converts linear motion into rotational motion of the cam rotating part. The transmission relationship between the cam rotating part and the swing-avoidance section converts the rotational motion into intermittent oscillation of the collecting component. The cam rotating part acts as the motion conversion hub, transmitting power and controlling the oscillation amplitude. The sliding connection at the end of the connecting rod on the support section creates a degree of freedom of motion. Combined with the constraint conditions of the hinge point, the oscillation angle of the swing-avoidance section is controlled by both water level changes and mechanical transmission. The collecting component adjusts its pitch angle according to the oscillation of the swing-avoidance section, expanding the collection coverage at low water levels and establishing an avoidance posture at high water levels. The intermittent reciprocating oscillation working mode is achieved through the asymmetric transmission of the cam mechanism, ensuring effective collection while avoiding energy loss caused by continuous motion.

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] refer to Figure 1 - Figure 6As shown, this embodiment provides a pond / lake waste recycling device, including a mobile platform 1, an adaptive adjustment component 2 and a collection component 3 mounted on the mobile platform 1. The adaptive adjustment component 2 includes a support part 21, a connecting rod part 22, a swing avoidance part 23, a cam rotation part 24, and a sliding part 25 mounted on the mobile platform 1. The collection component 3 is mounted on the swing avoidance part 23. The sliding part 25 is externally connected to a floating component. One end of the connecting rod part 22 is hinged to the center of the swing avoidance part 23, and the other end of the connecting rod part 22 is slidably connected to the support part 21. The cam rotation part 24 and the sliding part 25 are both mounted on the support part 21. The sliding part 25 is drively connected to the cam rotation part 24, and the cam rotation part 24 is drively connected to the swing avoidance part 23. The sliding part 25 drives the cam rotation part 24 to rotate in response to water level changes. The cam rotation part 24 drives the swing avoidance part 23 to intermittently swing back and forth relative to the hinge point of the connecting rod part 22. The floating component senses the water level changes. The system detects water level changes and drives the sliding part 25 to generate displacement. Then, the cam rotating part 24 converts the linear motion into rotational motion, ultimately driving the swing avoidance part 23 to cause the collection component 3 to swing intermittently back and forth. This achieves an adaptive adjustment function without any external power source or complex control system. This design has a simple and reliable structure, low maintenance cost, and rapid response. It can also achieve continuous attitude adjustment and periodic avoidance actions, which not only solves the limitations of static collection but also enhances the environmental adaptability and safety of the equipment. The floating part is a water surface floating component external to the sliding part 25. Based on the principle of buoyancy, it generates vertical displacement with the rise and fall of the water level: when the water level rises, the floating part floats up under the action of buoyancy, pushing the sliding part 25 to move upward; when the water level falls, the floating part sinks down, driving the sliding part 25 to move downward, thus converting the water level change into mechanical displacement, driving the subsequent cam rotating part 24 and the swing avoidance mechanism to achieve adaptive adjustment.

[0021] Currently, most pond and lake waste collection devices use collection mechanisms fixedly mounted on floating platforms. Their working posture is fixed during manufacturing. While simple in structure and low in cost, and capable of completing cleanup operations at standard water levels, they cannot adapt to seasonal fluctuations in water levels. When water levels drop, the collection range is insufficient; when water levels rise, they are prone to collisions with obstacles in the water, leading to decreased efficiency and equipment damage. Furthermore, they lack the intelligent adjustment capability to automatically adjust their posture and avoid obstacles based on water levels.

[0022] To address the technical shortcomings of existing pond and lake waste recycling devices, which suffer from reduced collection efficiency and susceptibility to collision damage due to fixed collection mechanism posture caused by water level fluctuations, this embodiment employs a novel approach. When the water level decreases, the floating component sinks, driving the sliding part 25 downwards. The cam rotation part 24 adjusts the angle of the swing avoidance part 23, causing the collection component 3 to tilt downwards to maintain full contact with the water surface. When the water level rises, the floating component rises, pushing the sliding part 25 upwards. This adjusts the angle of the collection component 3 accordingly and actively avoids obstacles such as aquatic plants and driftwood through an intermittent swing function, preventing rigid collisions and equipment jamming. Simultaneously, the entire system continuously adjusts its working posture according to real-time water level changes, completely overcoming the limitations of fixed posture design and ensuring optimal collection performance and equipment safety under any water level conditions.

[0023] During the transmission and cooperation between the cam rotating part 24 and the sliding part 25, if the cam structure design is unreasonable, it may lead to discontinuous motion trajectory or transmission jamming, thereby affecting the precise drive of the cam rotating part 24 to the swing avoidance part 23 when the water level changes. This will prevent the stable swing and avoidance function of the collecting component 3 under different water levels from being guaranteed. To address this, the cam rotating part 24 is further proposed to include a rotating block 241 and a protrusion 242 provided on the rotating block 241. The rotating block 241 is provided with an arc-shaped groove 243 and a vertical groove 244. The vertical groove 244 and the arc-shaped groove 243 are connected. The three interconnected guide grooves form a guide groove. The rotating block 241 serves as the cam body, and its protrusion 242 is used to contact the guide block 26 of the swing avoidance part 23 to directly transmit the driving force. The guide groove formed by the arc groove 243 and the vertical groove 244 provides a movement path for the guide rod 254 of the sliding part 25. The curved characteristics of the arc groove 243 guide the rotating block 241 to rotate periodically, while the vertical groove 244 allows the guide rod 254 to switch the direction of movement at a specific position, thereby converting the water level change response of the sliding part 25 into the intermittent rotation of the rotating block 241.

[0024] Because the guide groove structure of the cam rotating part 24 has a mismatch in the degrees of freedom of motion, directly using a floating part to drive the rotating block 241 can easily lead to motion interference or jamming between the slider 252 and the rotating block 241, making it impossible to achieve stable linkage control of vertical sliding and rotational motion. In this regard, in one embodiment, the sliding part 25 is further proposed to include a limiting seat 251, a slider 252 and a first spring 253. The limiting seat 251 is fixed on the support part 21 and has a vertical groove 255. The slider 252 is slidably disposed in the groove 255. The two ends of the first spring 253 are respectively connected to the sliding part 252. The bottom of block 252 and slide 255 are connected. A guide rod 254 is provided on the slider 252. The guide rod 254 extends into the guide groove formed by the vertical groove 244 and the arc groove 243. When the floating component drives the slider 252 to move, the rigid sidewall of the slide 255 constrains the slider 252 to deflect, ensuring that the compression stroke can be completed by overcoming the spring resistance when the water level drops. In practical applications, when the water level rises, the floating component floats up and pushes the slider 252 to move upward in the slide 255, compressing the first spring 253. The guide rod 254 moves with the slider 252 and slides in the guide groove, causing the rotating block 241 to rotate. When the water level drops, the elastic force of the first spring 253 drives the slider 252 to drop, and the guide rod 254 slides in the opposite direction in the guide groove, causing the rotating block 241 to rotate in the opposite direction. Through the rigid fixing structure of the limiting seat 251 and the slide 255, a vertical motion constraint channel is established for the slider 252, so that the floating component retains only a single degree of freedom when driving the slider 252. The elastic connection design of the first spring 253 allows the slider 252 to compress within the groove 255 in response to a drop in water level, and also enables automatic reset through the spring's restoring force when the water level rises, forming a bidirectional adaptive adjustment capability. The guide rod 254, in conjunction with the composite guide groove formed by the vertical groove 244 and the arc-shaped groove 243 on the rotating block 241, converts the linear motion of the slider 252 into alternating forward and reverse rotation of the rotating block 241. The vertical groove 244 segment enables rapid positioning of the initial angle of the rotating block 241, while the arc-shaped groove 243 segment controls the uniform rotation phase of the rotating block 241 through its curved profile. This mechanical linkage structure effectively solves the nonlinear relationship between water level fluctuations and the angular displacement of the rotating block 241, ensuring that the attitude adjustment process of the collection component 3 is free of dead spots and impacts.

[0025] However, during the continuous rotation of the cam, if the protrusion 242 is in direct and continuous contact with the rocker avoidance part 23, it will cause motion interference or unstable transmission of driving force, which in turn will cause equipment to stall or components to wear out. To avoid this problem, in one embodiment, guide blocks 26 are respectively provided on both sides of the hinge point between the rocker avoidance part 23 and the connecting rod part 22. The protrusion 242 is in intermittent contact with one of the guide blocks 26, driving the rocker avoidance part 23 to swing relative to the hinge point. By symmetrically providing guide blocks 26 on both sides of the hinge point between the rocker avoidance part 23 and the connecting rod part 22, the protrusion 242 of the cam rotating part 24 only contacts one side of the guide block during rotation. Block 26 forms intermittent contact. When protrusion 242 contacts a certain side guide block 26, it pushes the swing avoidance part 23 to swing around the hinge point to that side. When it is out of contact, the swing avoidance part 23 can be reset by gravity. This design, through the periodic cooperation between the spatially separated guide block 26 and protrusion 242, transforms the continuous rotation of the cam into the intermittent swing action of the swing avoidance part 23. This avoids the frictional loss caused by the continuous contact between protrusion 242 and swing component, and achieves controllable swing amplitude and frequency through the intermittent drive mode. This ensures that the collection component 3 can actively adjust its attitude at different water levels and reduce the risk of rigid collision with obstacles.

[0026] Furthermore, the protrusion 242 has a triangular structure with curved edges. By designing the protrusion 242 as a triangular structure, its geometry optimizes the contact trajectory with the guide block 26. The apex of the triangle serves as the starting point for precise triggering of the swing motion, while the curved design of the two sides effectively reduces the impact force at the moment of contact. During the rotation of the cam, the curved edges form a smooth transition of rolling friction with the guide block 26, reducing vibration and noise caused by rigid collisions, and avoiding component wear caused by sharp edge scratches. The three curved sides of the triangular structure form a continuous gradient surface, allowing the protrusion 242 to dynamically adjust the contact angle according to changes in water level during rotation, ensuring the reliability of intermittent drive and improving the smoothness of avoidance actions.

[0027] Furthermore, during the operation of the adaptive adjustment component 2, if the connecting rod 22 adopts a single rigid connection method, the swing avoidance part 23 will lack buffering capacity when swinging, and will be unable to adapt to the instantaneous impact caused by water level fluctuations. At the same time, uneven force may cause structural deformation or jamming, affecting the stability and reliability of the device operation. In this regard, in one embodiment, the connecting rod 22 includes a first connecting rod 221, a second connecting rod 222, and a third connecting rod 223. The two ends of the second connecting rod 222 are respectively hinged to one end of the first connecting rod 221 and one end of the third connecting rod 223. The other end of the third connecting rod 223 is slidably mounted on the guide rail 224. On the support part 21, the other end of the third connecting rod 223 is connected to the bottom wall of the guide rail 224 via a second spring 225, and the other end of the first connecting rod 221 is hinged to the swing avoidance part 23. Through the linkage structure combining multi-segment hinges and elastic sliding, the transmission performance of the adaptive adjustment component 2 is optimized. The first connecting rod 221 is hinged to the swing avoidance part 23, directly transmitting the swinging motion. The second connecting rod 222, as an intermediate connector, forms a movable triangular structure with the first connecting rod 221 and the third connecting rod 223 through hinges at both ends, enhancing the degree of freedom of the linkage part 22 during the swinging process and avoiding stress concentration caused by rigid connection. The third connecting rod 223 is slidably mounted on the support part 21 via the guide rail 224 and is connected to the bottom wall of the guide rail 224 via the second spring 225, so that the sliding of the third connecting rod 223 on the support part 21 has elastic buffering capability. When the water level changes and the floating component drives the sliding part 25, the sliding of the third connecting rod 223, in conjunction with the extension and retraction of the second spring 225, can absorb the impact force brought by the water level fluctuation. At the same time, the spring's reset action ensures that the connecting rod part 22 returns to its initial state after dynamic adjustment, thereby improving the stability and anti-interference ability of the device operation.

[0028] Furthermore, during the movement of the connecting rod 22, the first connecting rod 221 may swing beyond its design range due to water level fluctuations or external resistance, leading to structural instability or interference with other components, affecting the reliability and collection efficiency of the device. Therefore, in one embodiment, limiting rods 27 are provided on the support portions 21 on both sides of the first connecting rod 221 to restrict its range of motion. By providing limiting rods 27 on both sides of the support portions 21, the swing amplitude of the first connecting rod 221 is physically constrained, thereby solving the problem of its excessive movement. Specifically, the limiting rods 27 are symmetrically distributed on both sides of the first connecting rod 221, forming a bidirectional blocking structure. When the first connecting rod 221 swings due to water level changes or external impacts, the limiting rods 27 restrict its left and right swing angles through rigid contact, ensuring that the connecting rod 22 only moves within a preset safe stroke. This design avoids excessive deflection of the first connecting rod 221, which could lead to mechanical interference with the support part 21 or other components. It also maintains the transmission accuracy between the connecting rod part 22, the cam rotating part 24, and the sliding part 25, thus ensuring the overall stability of the adaptive adjustment assembly 2. Furthermore, the symmetrical layout of the limiting rod 27 ensures balanced force distribution, reduces unilateral wear, extends the device's service life, and ensures that the coverage area of ​​the collecting assembly 3, driven by the swing avoidance part, remains controllable.

[0029] When the water level changes, causing the sliding part 25 to drive the cam rotation part 24, the swing avoidance part 23, due to its rigid structure with a fixed hinge point, cannot dynamically optimize the avoidance angle of its swing arm 232 according to the water level fluctuation. This results in the contact angle between the swing arm 232 and the water surface being unable to adapt to the garbage collection needs under different water levels, which may cause insufficient collection range or increased risk of collision with obstacles. To avoid this problem, in one embodiment, the swing avoidance part 23 includes a central connecting block 231 and a swing arm 232 disposed on the central connecting block 231. The central connecting block 231 is hinged to the other end of the first connecting rod 221. The angle between the swing arm 232 and the horizontal plane is adjusted within the range of 15°-20° when the water level changes. Through the hinge design between the central connecting block 231 and the first connecting rod 221, the swing arm 232 can swing around the hinge point, thereby achieving dynamic angle adjustment under the drive of the adaptive adjustment component 2. The central connecting block 231 serves as the core support for the swing arm 232, transmitting the movement of the connecting rod 22 via a hinge to ensure the controlled swing trajectory of the swing arm 232. The swing arm 232 directly contacts the water surface, with its included angle limited to 15°-20°. This ensures that the swing arm 232 can fully approach the water surface to expand the collection range at low water levels, while avoiding rigid collisions with obstacles due to excessive angles at high water levels. Specifically, the minimum angle of 15° ensures that the collection component 3 can still effectively contact surface debris under low water conditions, while the maximum angle of 20° reduces the probability of contact with obstacles in the water by moderately raising the swing arm 232. This angle range balances collection efficiency and obstacle avoidance capabilities, preventing structural instability or decreased adjustment accuracy due to an excessively wide angle adjustment range.

[0030] Following the above embodiment, an arc-shaped groove 243 and a vertical groove 244 are formed on the rotating block 241 to create a guide groove for guiding the movement of the sliding part 25. However, in this process, the distribution of the arc-shaped grooves 243 when the rotating block 241 rotates may cause the guide rod 254 to experience discontinuous trajectory or poor transition during its movement within the groove. When the water level fluctuates frequently, the sliding part 25 needs to repeatedly respond to the rotation of the rotating block 241. If there is a lack of an effective transition structure between adjacent arc-shaped grooves 243, the guide rod 254 may easily become stuck or... Interruption of motion affects the transmission stability between the cam rotating part 24 and the sliding part 25. In one embodiment, the rotating block 241 is rotatably mounted on the support part 21. An arc-shaped groove 243 is provided every 180° along the circumference of the rotating block 241. Adjacent arc-shaped grooves 243 are connected by a vertical groove 244. The rotating block 241 is rotatably mounted on the support part 21, which provides stable rotational support, ensuring that the rotating block 241 can rotate smoothly around a fixed axis when driven by the sliding part 25. The arc-shaped groove 243 is provided every 180° along the circumference of the rotating block 241, so that the rotating block 241 forms two symmetrically distributed arc-shaped groove 243 regions during one rotation. Each arc-shaped groove 243 corresponds to one lifting stroke of the slider 252 in the groove 255, thereby converting the continuous rotation of the rotating block 241 into the periodic lifting motion of the sliding part 25. Two adjacent arc-shaped grooves 243 are connected by a vertical groove 244. The vertical groove 244 serves as a transition channel. When the rotating block 241 rotates to the switching position of the adjacent arc-shaped groove 243, the guide rod 254 smoothly transitions from the end of the current arc-shaped groove 243 to the beginning of the next arc-shaped groove 243 along the vertical groove 244. This prevents the guide rod 254 from leaving the track or getting stuck due to the lack of a connecting structure between the grooves. It ensures that the sliding part 25 can continuously drive the rotating block 241 to rotate when the water level changes, thereby maintaining a stable transmission relationship between the cam rotating part 24 and the swing avoidance part 23. In addition, the above embodiments use a swing arm 232 to adjust the angle of the swing avoidance section 23 to cope with water level changes. However, when the swing arm 232 swings, the specific setting of its end collection component 3 is not clearly defined, which may result in insufficient flexibility in adjusting the contact angle and coverage of the collection component 3 with the water surface. This makes it impossible to optimize collection efficiency according to the type of waste or the distribution of obstacles. Furthermore, the fixed collection structure limits the obstacle avoidance function. In one embodiment, the collection component 3 is set at the end of the swing arm 232. The collection component 3 is a collection net or a collection plate. By defining the specific setting and type of the collection component 3, combined with the dynamic adjustment function of the swing arm 232, efficient collection of surface waste and obstacle avoidance are optimized in tandem. By setting the collection component 3 at the end of the swing arm 232 and utilizing the swing characteristics of the swing arm 232, the collection component 3 can adjust its contact angle with the water surface according to water level changes, thereby expanding or shrinking the coverage area to adapt to the waste distribution characteristics under different water levels. The selection and design of the collection net or collection plate can be flexibly matched according to the type of waste (such as floating or suspended matter) to improve collection efficiency. The swing avoidance unit 23 dynamically adjusts the attitude of the collection component 3 by changing the swing amplitude of the swing arm 232. This reduces the contact angle with the water surface at high water levels to avoid collisions with obstacles, while increasing the contact angle at low water levels to expand the collection range. The synergistic effect of these technical features enables the device to maintain stable collection capabilities and actively avoid obstacles in complex water environments, overcoming the shortcomings of fixed collection structures in terms of adaptability.

[0031] The working principle and workflow of this invention: This invention employs an adaptive adjustment mechanism, the core of which lies in utilizing Archimedes' principle of buoyancy and the motion conversion characteristics of a cam mechanism. When the water level changes, the floating component externally connected to the sliding part 25 experiences a change in buoyancy. Through the dynamic balance between the elastic restoring force of the first spring 253 and the buoyancy, the slider 252 is driven to perform vertical reciprocating motion within the groove 255 of the limiting seat 251. The guide rod 254 on the slider 252 extends into the guide groove of the cam rotating part 24, converting the linear motion of the sliding part 25 into the rotational motion of the rotating block 241 via the cam mechanism. The triangular protrusion 242 on the rotating block 241 intermittently contacts the guide blocks 26 on both sides of the rocking avoidance part 23, forming a periodic pushing and pulling action.

[0032] The entire workflow is divided into three stages: sensing, transmission, and execution. In the sensing stage, the floating component experiences vertical displacement due to water level fluctuations, which is smoothly transmitted to the slider 252 via the buffering effect of the first spring 253. In the transmission stage, the linear motion of the slider 252 drives the cam rotating part 24 to rotate via the guide rod 254. The special geometry of the triangular protrusion 242 ensures intermittent contact with the guide block 26. In the execution stage, the protrusion 242 pushes the guide block 26, causing the swinging avoidance part 23 to swing back and forth within a range of 15°-20° around the hinge point of the connecting rod part 22. This drives the collection assembly 3 mounted on the swing arm 232 to sweep across the water surface, achieving active collection of waste. The multi-section hinged structure of the connecting rod part 22, with the first, second, and third connecting rods 223 providing buffering via the second spring 225, ensures that the system maintains a stable swinging posture under different water level conditions. Simultaneously, the limiting rod 27 prevents excessive swinging from damaging the mechanism.
