A flexible scraping-type water surface garbage cleaning device

Abstract

This invention provides a flexible, scraping-type surface debris cleaning device, primarily consisting of a hull, a movable shaft assembly, an air pump, a debris-blocking strip, a hinge, a mounting cavity, a sliding cavity, a limiting block, an active rotating shaft, a rotating seat, a buoyancy wheel, and an auxiliary swing frame. The beneficial effects are as follows: the interaction between the pendulum ball on the swing arm and the auxiliary swing frame causes the lever to repeatedly rotate, generating repeated twisting motions. This allows the scraper to sweep across the plants while removing debris. The ingenious design allows for adjusting the torque of the lever during rotation by changing the pendulum balls of different weights, thereby adjusting the pressure applied by the scraper as it sweeps across the plants. This achieves flexible cleaning, removing debris, withered flowers, and dead leaves from floating plants while minimizing damage to the plant stems, thus protecting aquatic plants and flowers.

Description

Technical Field

[0001] This invention relates to the field of water surface debris cleaning technology, and in particular to a flexible scraping-type water surface debris cleaning device. Background Technology

[0002] Using aquatic plants to embellish the water surface not only enriches its layers but also adds visual interest through their ornamental value. As producers within the natural ecosystem, aquatic plants possess the inherent ability to purify and remediate water pollution, thus enabling floating plants to serve both water purification and aesthetic appeal.

[0003] Floating flowers have roots growing in the soil and leaves floating on the water surface. These include plants in water depths of 1.5 to 3 meters, but are generally cultivated in water depths of less than 80 cm. However, once mixed with white garbage, foam, and other household waste, they are difficult to clean. Furthermore, the waste produced by the plants after metabolism, such as withered flowers and leaves, not only affects the landscape but also the water quality. Therefore, they should be removed promptly. Existing mechanized cleaning methods may directly cut off the stems of the flowers during operation, thus affecting their growth. Summary of the Invention

The inner and outer sides of the bearing 54 are respectively interference-fitted onto the drive shaft 5 and the rotating seat 55. The rotating sleeve 52 and the rack 103 are respectively fixed at the upper and lower ends of the drive shaft 5. A first-stage push rod 42, a second-stage push rod 43, and a third-stage push rod 41 are sequentially provided between the motor 4 and the rack 103. Push rod 42, secondary push rod 43, and tertiary push rod 4 are connected sequentially by hinge 44 to form a linkage structure; auxiliary swing frame 7 is fixedly connected to the side of rotary seat 55, and a primary swing track 71, a secondary swing track 72, and a tertiary swing track 73 are sequentially provided on the top surface of the auxiliary swing frame 7. The secondary swing track 72 is located between the primary swing track 71 and the tertiary swing track 73, and is higher than the primary swing track 71 and the tertiary swing track 73; a lever 9 is provided inside the rotating sleeve 52. The lever 9 is inserted into the rotating sleeve 52 and can rotate and twist. A lever 91 and a swing sleeve 6 are respectively provided at the front and rear ends of the lever 9. The swing sleeve 6 is fixedly connected to the rear of the lever 9; a swing plate 62, a swing rod 63, and a swing ball 64 are provided on the swing sleeve 6. The swing plate 62 and the swing rod 63 are fixedly connected to the swing plate 65. On the upper and lower sides of the horizontal plane of the sleeve 6, the pendulum ball 64 is fixed to the lower end of the pendulum rod 63, and the pendulum ball 64 hangs on the top surface of the auxiliary pendulum frame 7 and can slide along it; the rotating sleeve 52 is provided with a rotating frame 51 and a limiting shaft 53, the limiting shaft 53 is fixed to the rear of the rotating frame 51, and the limiting shaft 53 and the rotating frame 51 form a "convex" shape and are fixedly connected to the rotating sleeve 52; the pendulum plate 62 is provided with a pendulum groove 61, the pendulum groove 61 is sleeved on the limiting shaft 53 and can tilt and swing to both sides of the limiting shaft 53; there are multiple floating pressure wheels 8, which are evenly and rotatably arranged in a straight line at the front end of the hull 1, and elastic plates 82 are evenly distributed in the circumferential direction inside the floating pressure wheel 8, and elastic brushes 81 are evenly distributed in the circumferential direction on the side; the front end of the hull 1 is provided with a water leakage hole 105.

[0030] In this embodiment, the bottom of the movable shaft assembly 25 is fixedly connected to the middle of the rear end of the hull 1. The top U-shaped pressure port 23 of the movable shaft assembly 25 is U-shaped hollow opening. The U-shaped pressure port 23 can rotate on the top of the movable shaft assembly 25. The air outlet rod 24 is movably locked in the U-shaped pressure port 23. The front end of the air outlet rod 24 is provided with a control handle 22 fixedly connected to it. The air outlet rod 24 is controlled by the control handle 22 to drive the hull 1 in the direction of travel.

[0031] In this embodiment, the sliding cavity 32 has a concave cross-section and the adjusting block 31 has a convex cross-section. The positional relationship between the sliding cavity 32 and the adjusting block 31 is limited by the cooperation of the concave and convex shapes. The adjusting block 31 is fitted inside the sliding cavity 32 and can move up and down.

[0032] In this embodiment, the adjusting screw 3 can be self-locked in conjunction with the adjusting block 31, so that after the adjusting screw 3 stops rotating, the relative height between the adjusting block 31 and the hull 1 can be limited.

[0033] In this embodiment, the connection end between the three-stage push rod 41 and the rack 103 is provided with a toothed sleeve 102. The toothed sleeve 102 can slide up and down on the rack 103 and can drive the rack 103 to rotate during the movement of the three-stage push rod 41.

[0034] In this embodiment, the connection between the first-level swing track 71, the second-level swing track 72 and the third-level swing track 73 is a curved transition at the top surface, and the auxiliary swing frame 7 is a circular arc plate with a forward protrusion in the middle, and its center is located on the axis of the active rotating shaft 5.

[0035] In this embodiment, the paddle 91 is a latex paddle, and one side of the paddle 91 is smooth, while the other side of the paddle 91 is provided with a groove 92, which is a concave hook shape.

[0036] In this embodiment, the pendulum ball 64 and the rear end of the pendulum rod 63 are connected by a thread, and the torque of the lever 9 during rotation is adjusted by replacing the pendulum ball 64 with one of different weights.

[0037] In this embodiment, multiple elastic brushes 81 are evenly distributed on both sides of the floating pressure wheel 8 along the circumferential direction, so as to facilitate the washing of flowers and adjacent floating pressure wheels 8 during the rolling process; the elastic sheet 82 has an S-shaped cross-section, so as to provide flexible support for the floating pressure wheel 8, and thus facilitate the protection of the floating pressure wheel 8 when it passes over the flowers.

[0038] First, the air vent 24 is engaged in the U-shaped pressure port 23. The air vent 24 is controlled by the control handle 22 to drive the hull 1 in the direction of travel.

[0039] Then, the motor 4 is turned on. The motor 4 drives the rack 103 inside the gear sleeve 102 to rotate through the first-stage push rod 42, the second-stage push rod 43 and the third-stage push rod 41. At this moment, the rack 103 drives the drive shaft 5 to rotate on the rotating seat 55. At the same time, the lever 9 inserted in the rotating sleeve 52 follows the drive shaft 5 to rotate.

[0040] At this time, the lever 9 drives the paddle 91 to swing, thereby scraping the water surface. The pendulum sleeve 6 at the tail of the lever 9 drives the pendulum ball 64 on the pendulum 63 to slide on the first-level pendulum track 71, the second-level pendulum track 72, and the third-level pendulum track 73. After the pendulum ball 64 on the pendulum 63 slides on the first-level pendulum track 71, the second-level pendulum track 72, and the third-level pendulum track 73 in sequence, the paddle 91 needs to be reset. At this moment, the pendulum ball 64 on the pendulum 63 needs to adjust its direction and slide on the third-level pendulum track 73, the second-level pendulum track 72, and the first-level pendulum track 71 in sequence. In other words, during this process, the actuating surface of the lever 9 and the paddle 91 is changed, so that during one scraping and resetting process, the smooth side of the paddle 91 of the lever 9 sweeps over the aquatic plants, thereby reducing the damage of the paddle 91 to the plants.

[0041] During this process, as the active rotating shaft 5 drives the lever 9 to rotate, the active rotating shaft 5 drives the lever 9 to rotate repeatedly. At the same time, through the cooperation between the pendulum ball 64 on the pendulum 63 and the auxiliary pendulum frame 7, the lever 9 is repeatedly twisted during its repeated rotation, so that the lever 91 has a sweeping motion over the flowers and plants when it moves the garbage. The design is ingenious.

[0042] Meanwhile, the pendulum ball 64 and the end of the pendulum rod 63 are connected by threads. By replacing the pendulum ball 64 with different weights, the torque of the lever 9 during rotation can be adjusted, thereby adjusting the pressure applied by the lever 91 when it sweeps over the flowers and plants.

[0043] When it is necessary to adjust the water sweep depth of the paddle 91 on the lever 9, the adjusting screw 3 is used for adjustment. That is, the adjusting screw 3 can be self-locked with the adjusting block 31. After the adjusting screw 3 is stopped, the relative height between the adjusting block 31 and the hull 1 can be limited. During this process, the toothed sleeve 102 at the end of the third-stage push rod 41 slides on the toothed rod 103. That is, the relative height between the rotating seat 55, which is fixedly connected to the adjusting block 31, and the hull 1 can be adjusted. This allows the relative height between the active rotating shaft 5 and the lever 9 installed above the rotating seat 55 and the hull 1 to be adjusted, thereby adjusting the water sweep depth of the paddle 91 on the lever 9.

[0044] During this process, the elastic brushes 81, which are evenly arranged on both sides of the floating pressure wheel 8, can wash the flowers and the adjacent floating pressure wheel 8 during the rolling process.

[0045] During or after use, the air outlet 24 is taken out from the U-shaped pressure port 23. The air outlet 24 is controlled by the control handle 22 to blow the elastic plate 82 on the floating pressure wheel 8. At this time, the floating pressure wheel 8 rotates and drives the elastic brush 81 to rotate, so that the adjacent floating pressure wheel 8 achieves the purpose of cleaning.

[0046] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
