[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0029] like Figure 1 and Figure 2The present invention discloses a buffered telescopic device for a cleaning device, comprising a base plate 1, a support arm 2, a spring 3, and two support sliding assemblies 4. The two support sliding assemblies are disposed at either end of the base plate. The support arm extends through the two support sliding assemblies in sequence and is slidably connected to the two support sliding assemblies. The spring is disposed along the length of the support arm, with one end connected to the support arm and the other end connected to one of the support sliding assemblies. When the cleaning device collides with a dock, the support arm slides toward the rear end along the two support sliding assemblies, and the spring acts as a buffer, preventing damage to the cleaning device. Furthermore, the spring ensures that the cleaning disc at the front end of the cleaning device is always in close contact with the dock surface, effectively improving the cleaning effect and preventing vacuum adsorption and recovery of wastewater. To ensure the stability of the buffered telescopic device, two springs are provided, symmetrically distributed on either side of the support arm. The two springs are located between the two support sliding assemblies and connected to the support sliding assembly closest to the cleaning device. Hanging rings 5 ​​are connected to each end of the spring, which are threadedly connected to the support arm or support frame to facilitate disassembly and replacement of the springs. In this embodiment, there are two base plates, symmetrically distributed on either side of the support arm, to improve structural strength.

[0030] Combine Figure 3 and Figure 4 As shown, the support sliding assembly includes a support frame 401, which is equipped with at least two rollers 402 that clamp the support arm. Each roller is rotatably connected to the support frame, and the number of rollers can be adjusted as needed. The support arm conforms to the outer surface of each roller. When the cleaning device is impacted and squeezed by the dock, the support arm drives each roller to rotate, thereby achieving a telescopic sliding effect. The rollers are rotatably connected to a fixed shaft 403 on the support frame via a bearing 14. The fixed shaft is detachably connected to the support frame, facilitating roller replacement and maintenance. The fixed shaft is assembled and connected to a fixing hole on the support frame, and the ends are threadedly connected using nuts 13 to achieve securement. The rollers include at least two vertical rollers 4021 symmetrically distributed on the left and right sides of the support arm, and at least two transverse rollers 4022 symmetrically distributed on the upper and lower sides of the support arm. The vertical rollers are perpendicular to the central axis of the transverse rollers. The transverse rollers clamp and secure the support arm vertically, while the vertical rollers clamp and secure the support arm horizontally (perpendicular to the sliding direction of the support arm), thereby ensuring smooth movement of the support arm. In this embodiment, the number of the transverse rollers is four, and each two transverse rollers form a group. The two groups of transverse rollers are symmetrically distributed on both sides of the two vertical rollers.

[0031] Combine Figure 1 、 Figure 2 and Figure 5As shown, the bottom of the base plate is provided with a bottom beam 6 perpendicular to it, and a first waist-shaped hole 7 is provided on the base plate. The first waist-shaped hole and the positioning hole 8 provided on the bottom beam are assembled and connected by bolts. By connecting the base plate to the aerial vehicle, the base plate and the support arm can be effectively installed. At least two second waist-shaped holes 9 are evenly spaced at both ends of the base beam. A U-shaped buckle 10 is detachably connected between two of the second waist-shaped holes at each end of the base beam. The position and model of the U-shaped buckle can be freely adjusted as needed. The U-shaped buckle is used to fix and install with the hanging basket 16 of the aerial vehicle. The end of the U-shaped buckle is threadedly connected with a nut 13 to achieve locking and fixation of the U-shaped buckle and the hanging basket 16.

[0032] In order to prevent the operator's hands from being accidentally clamped by the roller when disassembling and assembling the support arm and the two supporting sliding assemblies, and to effectively protect the roller and spring and extend their service life, a first protective cover 11 is provided on the outside of each support frame to cover all the rollers, and a second protective cover 12 is provided between the two support frames to cover the springs.

[0033] The working principle of this utility model is as follows:

[0034] like Figure 5 As shown, during use, the two bottom beams 6 are bolted to the bottoms of the two base plates 1. Then, according to the specifications of the aerial vehicle's hanging basket 16, matching U-shaped buckles 10 are used to select the appropriate position for installation. When cleaning the dock, by controlling the movement of the aerial vehicle and the hanging basket 16, the cleaning device 15 at the front end of the support arm 2 can be controlled to clean and derust the dock surface. After use, the support arm can be directly withdrawn from the two support slide assemblies, reducing the occupied space and making operation simple and convenient.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
