Description

Technical Field

[0001] This utility model relates to the field of horizontal cleaning boat technology, and more specifically, to a water surface cleaning boat with an automatically swinging collection arm. Background Technology

[0002] It is known that surface cleaning vessels are mainly used in rivers and lakes to clean up surface garbage and floating objects. As a result, surface cleaning vessels are often equipped with cleaning swing arms. Existing cleaning swing arms have different forms such as horizontal rotation and vertical rotation. They are all connected to the catamaran hull and the cleaning swing arm through cylinders or other telescopic devices. The cleaning swing arm rotates around the catamaran hull to clean the water surface.

[0003] However, in actual use, the cylinder or other telescopic devices are suspended in the air during the deployment of the cleaning arm. Long-stroke cylinders or other telescopic devices are large in size and weight. If they are suspended in the air, they will deform significantly, affecting their lifespan. Therefore, it is not possible to install long-stroke cylinders or other telescopic devices. If short-stroke cylinders or other telescopic devices are used, a more powerful cylinder is required to achieve a larger rotation angle of the cleaning arm, resulting in higher equipment costs and shorter service life.

[0004] Therefore, a water surface cleaning boat with an automatically swinging collection arm is proposed as a further improvement, so that the cleaning arm not only has a large rotation angle, but also low energy consumption. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a water surface cleaning boat with an automatically swinging collection arm to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water surface cleaning boat with an automatically swinging collection arm, comprising a catamaran hull, one end of which is designated as the bow, and a garbage compartment for collecting surface garbage is provided inside the catamaran hull, the garbage compartment being connected to the outside in the direction facing the bow; the bow is rotatably connected to two inner sides of the garbage compartment, the swing arm being used to collect surface garbage;

[0007] The top of each side of the bow near the two swing arm bodies is connected to the adjacent swing arm bodies via an automatic telescopic component. The extension and retraction of the automatic telescopic component drives the swing arm bodies to swing along the horizontal plane.

[0008] A support plate connected to the bottom of the garbage bin is fixedly installed at the bottom of the bow. A caster wheel is fixedly installed at the bottom of the swing arm body near the support plate. The caster wheel, which supports the swing arm body, slides on the upper surface of the support plate.

[0009] Furthermore, a fixed frame is fixedly installed on the top of the swing arm body near the bow, and a rotating shaft perpendicular to the support plate is rotatably connected to the middle of the fixed frame. The two sides of the bow are respectively rotatably connected to adjacent automatic telescopic components, and the other end of the automatic telescopic components is rotatably connected to adjacent rotating shafts.

[0010] Furthermore, the top of the automatic telescopic component is detachably connected to a protective cover, which is detachably connected to the bow of the ship.

[0011] Furthermore, the swing arm body includes: a rectangular main frame and a rectangular sub-frame;

[0012] The main frame is movably fitted onto the outer surface of the sub-frame. One end of the main frame is rotatably connected to the catamaran hull in the horizontal direction. The sub-frame extends out from the end of the main frame away from the catamaran hull.

[0013] Furthermore, the lengths of both the main frame and the sub-frame are set between 1 and 3 meters.

[0014] Furthermore, the shapes of both the main frame and the sub-frame are set to a grid shape.

[0015] Furthermore, the shortest state of the automatic telescopic component corresponds to the fully extended state of the swing arm body; the longest state of the automatic telescopic component corresponds to the fully retracted state of the swing arm body.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, by setting up support plates and casters, the casters can support the swing arm body when it swings, effectively reducing friction and preventing the swing arm body from being affected by gravity or the weight of attached garbage for a long time, thus preventing excessive stress and deformation of related components; by setting up main and secondary frames, the swing arm body is extended, which helps to increase the actual area of ​​the swing arm body that can collect garbage on the water surface.

[0018] 2. Compared with existing technologies, by setting up automatic telescopic components to control the opening and closing of the swing arm body, the two swing arm bodies are opened into a trumpet shape, so that the swing arm body not only has a larger rotation angle, increasing the actual area for collecting water surface garbage; but also can quickly use water flow to collect water surface garbage when the swing arm body is closed; and by setting up protective covers, it is convenient to inspect and protect the automatic telescopic components, which helps to extend the service life of the automatic telescopic components.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] As attached Figure 1 Appendix Figure 2 and attached Figure 3 The illustrated surface cleaning vessel with an automatically swinging collection arm includes a catamaran hull 10, one end of which is designated as the bow a. The interior of the catamaran hull 10 has a garbage compartment 11 for collecting surface debris, which is connected to the outside environment facing the bow a. Swinging arm bodies 20 are rotatably connected to both inner sides of the garbage compartment 11 at the bow a, and these swinging arm bodies 20 are used to collect surface debris. Since one end of the swinging arm body 20 is horizontally connected to the inner side of the bow a at the garbage compartment 11 via two hinges at the top and bottom, it achieves a horizontal rotatable connection between one end of the swinging arm body 20 and the bow a.

[0028] The tops of both sides of the bow a, near the two swing arm bodies 20, are connected to the adjacent swing arm bodies 20 via automatic telescopic components 30. The extension and retraction of these automatic telescopic components 30 drives the swing arm bodies 20 to swing along the horizontal plane. Thus, one end of the automatic telescopic component 30 is rotatably connected to the catamaran hull 10 in the horizontal direction, and the other end of the automatic telescopic component 30 is rotatably connected to the swing arm body 20 in the horizontal direction. The two swing arm bodies 20 are symmetrically arranged along the axis of the catamaran hull 10. The extension and retraction of the automatic telescopic components 30 controls the swing of the swing arm bodies 20 in the horizontal plane. The swing directions of the two swing arm bodies 20 are opposite or in the same direction, so the two swing arm bodies 20 cooperate to form an unfolding or closing shape, which helps the swing arm bodies 20 guide surface garbage into the catamaran hull 10. Then, the garbage attached to the swing arm bodies 20 is flushed into the garbage bin 11 by the water flow.

[0029] A support plate 12 connected to the bottom of the garbage compartment 11 is fixedly installed at the bottom of the bow a. A caster wheel 13 is fixedly installed at the bottom of the swing arm body 20 near the support plate 12. The caster wheel 13 used to support the swing arm body 20 slides on the upper surface of the support plate 12.

[0030] When the swing arm body 20 swings, it is horizontally rotatably connected to the inner side of the catamaran hull 10 at the port of the garbage compartment 11 via two hinges at the top and bottom. This rotatable connection serves as a fulcrum. Near the fulcrum, the automatic telescopic component 30 pulls the swing arm body 20, and the universal wheel 13 is provided with a support surface through the support plate 12. This design uses the universal wheel 13 to support the end of the swing arm body 20, effectively achieving a large rotation angle of the swing arm body 20 with a short drive stroke, and with low energy consumption. Therefore, when the swing arm body 20 swings, the universal wheel 13 can effectively reduce friction and support the swing arm body 20, avoiding the long-term influence of gravity or the weight of garbage attachments, and preventing the relevant components from being deformed due to excessive force.

[0031] The catamaran hull 10 is symmetrically distributed along its axis. The swing direction of the two swing arms 20 during deployment and closure is conducive to collecting surface debris. When the two swing arms 20 are deployed, they form a large interception area. At this time, the debris will be adsorbed into the grid of the swing arms 20 due to the water flow. Therefore, the swing arms 20 need to be closed periodically. When the two swing arms 20 are closed, the angle between the two swing arms 20 and the inner wall of the debris compartment 11 of the catamaran hull 10 along the water flow direction is less than 180 degrees. As a result, the debris on the swing arms 20 is flushed back into the cargo compartment 11 by the water flow.

[0032] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3As shown, a fixed frame 14 is fixedly installed on the top of the swing arm body 20 near the bow a. A rotating shaft 15 perpendicular to the support plate 12 is rotatably connected to the middle of the fixed frame 14. Both sides of the bow a are rotatably connected to adjacent automatic telescopic components 30, and the other end of each automatic telescopic component 30 is rotatably connected to the adjacent rotating shaft 15. The automatic telescopic component 30 is configured as an automatic telescopic rod. When the automatic telescopic component 30 extends, it pushes the fixed frame 14 to move via the rotating shaft 15, which in turn causes the fixed frame 14 to extend the swing arm body 20. The area enclosed by the two swing arm bodies 20 increases, expanding the area for collecting surface debris. When the automatic telescopic component 30 retracts, it pulls the fixed frame 14 to move via the rotating shaft 15, which in turn causes the fixed frame 14 to close the swing arm bodies 20, ultimately resulting in the two retracted swing arm bodies 20 reaching a parallel state. The fixed frame 14 is U-shaped to facilitate the dispersion of the traction force exerted on the swing arm body 20 by the automatic telescopic component 30 during extension and retraction, preventing excessive force and damage to related parts.

[0033] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the top of the automatic telescopic component 30 is detachably connected to a protective cover 16. The protective cover 16 is detachably connected to the catamaran hull 10, which facilitates the maintenance and protection of the automatic telescopic component 30, thereby extending its service life.

[0034] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the swing arm body 20 includes: a rectangular main frame 21 and a rectangular sub-frame 22;

[0035] The main frame 21 is movably fitted onto the outer surface of the secondary frame 22. One end of the main frame 21 is rotatably connected to the catamaran hull 10 in a horizontal direction, and the secondary frame 22 extends from the end of the main frame 21 away from the catamaran hull 10. Both the main frame 21 and the secondary frame 22 of the swing arm body 20 are metal welded mesh-shaped frames. The main frame 21 has a slot inside, and the secondary frame 22 slides and is pulled out of the slot in the main frame 21 in a drawer-like manner. When the secondary frame 22 is fully inserted into the main frame 21, the total length of the swing arm body 20 is the length of the main frame 21. When the secondary frame 22 is pulled out of the main frame 21 to its maximum length, the total length of the swing arm body 20 is at its maximum. Thus, the length of the swing arm body 20 can be adjusted to prevent garbage from being pressed into the mesh of the main frame 21 and the secondary frame 22 by the water flow and thus prevent garbage from clogging the mesh, improving practicality.

[0036] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3As shown, the lengths of both the main frame 21 and the secondary frame 22 are set between 1 and 3 meters.

[0037] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the main frame 21 and the sub-frame 22 are both set to a grid shape; so that when the catamaran hull 10 moves forward, the grid-shaped main frame 21 and sub-frame 22 can reduce the resistance of the swing arm body 20 to the water flow.

[0038] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the shortest state at the automatic telescopic component 30 corresponds to the fully extended state of the swing arm body 20; that is, the area of ​​the swing arm body 20 when it is extended can reach the maximum, and the interception area of ​​the swing arm body 20 is the maximum at this time.

[0039] The longest state of the automatic telescopic component 30 corresponds to the fully retracted state of the swing arm body 20; that is, the angle between the two swing arm bodies 20 and the inner wall of the catamaran hull 10 along the direction of water flow is less than 180 degrees, so that the garbage on the swing arm body 20 is restricted by the swing arm body 20 due to the water flow and enters the garbage compartment 11.

[0040] The working principle of this utility model is as follows: When in use, the sub-frame 22 is first pulled out from the slot of the main frame 21 to determine the length of the swing arm body 20; then, the extension and retraction of the swing arm body 20 is controlled by the extension and retraction action of the automatic telescopic component 30. The arm body 20 is extended for 10 seconds and then retracted for 1 second, so that the garbage on the water surface can be instantly flushed into the cabin.

[0041] The specific working principle of the unfolding and retraction is as follows: When the automatic telescopic component 30 pushes the swing arm body 20 to unfold, it will expand the collection area of ​​garbage on the water surface. At this time, the garbage will be adsorbed into the grid of the swing arm body 20 due to the water flow. When the automatic telescopic component 30 pushes the swing arm body 20 to close, the garbage on the swing arm body 20 will enter the garbage compartment 11 due to the water flow. Therefore, the efficiency and effect of garbage collection are improved. Through low energy consumption and simple structure, the problem of small garbage collection area of ​​catamaran hull 10 and garbage not being able to automatically gather is solved.
