Description

Technical Field

[0001] The utility model relates to the field of water surface garbage cleaning devices, in particular to an unmanned floating object cleaning boat. Background Art

[0002] There are often floating objects on the water surface that need to be cleaned. Manual rowing on the water surface is inefficient, time-consuming, and costly. Salvagers on the water surface are also prone to sunburn, so unmanned boats are often used to clean up garbage on the water surface.

[0003] As people's environmental awareness increases, they realize that floating objects that frequently appear on the water surface need to be cleaned up in time to avoid water pollution. The traditional cleaning method is to salvage floating objects by manual boating, but this cleaning method has the disadvantages of low efficiency, too long time consumption and high cost. In addition, the salvagers work for a long time under the scorching sun and are also easily damaged by ultraviolet rays. In order to overcome these problems, unmanned boats are gradually used to clean floating objects instead of manual salvage. The cleaning method of unmanned boats is mainly to set a front shovel in the forward direction of the unmanned boat. During the movement of the unmanned boat, the floating objects are shoveled onto the boat instead of being salvaged on board. In order to prevent the floating objects from staying in front of the front shovel, the front shovel will also be used to clean the floating objects. There are swing arms on both sides, which are close to each other to form a relative area. Floating objects are blocked by the swing arms and cannot float away from the two sides of the front shovel. However, most swing arms are straight rods and are set on both sides of the front shovel. Due to the limitation of the swing angle and the obstruction of the front shovel, there is a certain limitation on the distance between the two swing arms. In addition, the two swing arms on the unmanned ship are currently independently controlled by motors, and the swings of the two swing arms are independent of each other. The two motors are often disturbed by setting accuracy and external factors such as shaking and rotation, resulting in inconsistent swing angles of the two swing arms. The above two points make it impossible for the two swing arms to offset each other to form a close connection. When the water surface fluctuates and the unmanned ship moves too fast, the floating objects are pushed forward, which greatly reduces the cleaning quality and efficiency. Utility Model Content

[0027] The implementation principle is that by setting two arms 1 to extend in an arc shape on the body 5, the physical spacing limitation of the two arms 1 on the side of the front shovel 2 away from the body 5 is eliminated, so that the two arms 1 can offset each other after approaching each other, and the two synchronously rotating shafts 8 are respectively the driving shaft and the driven shaft, which respectively drive the corresponding arms 1 to swing, and the first driving member 10 drives the driving shaft, and the driving shaft drives the driven shaft to rotate synchronously, so that the two arms 1 swing synchronously, that is, approach or move away synchronously, and in the process of synchronous swinging, the two arms 1 are always symmetrical to avoid mutual misalignment after swinging, so that the two arms 1 approach each other under the condition of synchronous swinging, can smoothly offset each other and form a closure, and the two arms 1 close together to intercept floating objects just in front of the front shovel 2, so as to prevent the unmanned boat from pushing the floating objects forward, thereby improving the cleaning quality and efficiency.

[0028] In this embodiment, the first driving member 10 can be an electric motor that can rotate forward and reverse, or a hydraulic motor that can rotate forward and reverse, etc. This embodiment does not impose too many restrictions on this.

[0029] As a further improvement, first transmission members 9 are respectively provided on the two rotating shafts 8 , second transmission members 11 are provided on the two first transmission members 9 , and the second transmission member 11 is arranged between the front shovel 2 and the machine body 5 .

[0030] The second transmission member 11 is arranged between the front shovel 2 and the machine body 5 to prevent garbage from falling from the front shovel 2 onto the machine body 5 and falling onto the second transmission member 11, so as not to interfere with the normal operation of the second transmission member 11, thereby protecting the second transmission member 11 and the swing stability of the boom 1.

[0039] The front shovel 2 adopts the structure of the second roller 22 of the conveyor belt, so that in addition to the relative thrust generated by the movement of the body 5 to push the floating objects onto the front shovel 2, the unmanned boat can also transport the floating objects on the second roller 22 of the conveyor belt to the body 5 through the rotation of the second roller 22 of the conveyor belt, thereby preventing the floating objects from staying on the front shovel 2 or falling back onto the water surface due to insufficient relative thrust, thereby improving the cleaning quality and efficiency.
