Description

Technical Field

[0001] The utility model relates to the technical field of panel cleaning devices, and particularly relates to a brush adjusting device suitable for panel cleaning. Background Art

[0002] The existing panel cleaning is often achieved by fixing the cleaning component through a carrier. For example, for the cleaning of the surface of a photovoltaic panel, a manned or unmanned carrier can be used to clean the open-air photovoltaic panel site. Since the terrain of the photovoltaic panel site cannot be actually leveled, and the splicing joints of adjacent photovoltaic panels are sometimes not completely aligned, when the cleaning component moves forward for cleaning, it is very difficult to always maintain a certain distance from the panel to be cleaned. The reaction of the existing cleaning mechanical structure to the electric control of the cleaning component is not sensitive enough, and there are defects in adjustment. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a brush adjusting device suitable for panel cleaning for the above-mentioned deficiencies of the existing technology. Through the setting of a floating support mechanism, it can adapt to the relative undulation between the photovoltaic panel and the ground, always maintain the distance between the brush component and the photovoltaic panel, ensure that the pressure between the brush component and the photovoltaic panel will not be too large, and the pressure is relatively stable, so as to enable the brush component to have a good cleaning effect.

[0004] The technical solution of the utility model is as follows:

[0005] A brush adjusting device suitable for panel cleaning includes a brush component and a carrier fixing frame. The brush adjusting device is arranged between the brush component and the carrier fixing frame, and is characterized in that: the brush adjusting device includes a main swing arm, a main rotating shaft is connected between the main swing arm and the carrier fixing frame, and a cross rotating shaft is connected between the main swing arm and the brush component.

[0006] Preferably, it further includes a floating support mechanism arranged on the brush component. The floating support mechanism includes a support wheel fixing arm, the support wheel fixing arm is connected with a support wheel connecting body, an upper rotating shaft I is connected between the support wheel connecting body and the support wheel fixing arm, and a support wheel is rotatably connected to the support wheel connecting body.

[0007] Preferably, the brush component is of a long strip structure, and two groups of mutually parallel support wheel fixing arms are arranged at the top of the brush component.

[0008] Preferably, the support wheel connecting body is respectively provided with a rotating shaft II and a rotating shaft III in the same horizontal direction below the rotating shaft I, and support wheels are arranged on both the rotating shaft II and the rotating shaft III. By adopting a floating support mechanism with two groups of double support wheels, the vibration of the brush component when crossing the plate seam is reduced, the overall stability of the brush component is increased, and the distance between the brush component and the panel surface is maintained.

[0009] Preferably, the cross shaft includes two perpendicular pin shafts, and the upper part of the cross shaft is hinged to one end of the main swing arm. The two perpendicular pin shafts enable the brush to rotate freely in the front-back, left-right directions, thus better adapting to the relative undulation between the panel surface and the ground.

[0010] Preferably, a lifting arm is fixedly connected to the upper part of the vehicle fixing frame, a winch is arranged at the front end of the lifting arm, and the power output of the winch is connected to the main swing arm. A winch can be added to the structure to lift the brush assembly by a steel wire rope or other ropes, belts, chains, so as to adapt the height of the brush assembly to the panel to be cleaned.

[0011] Preferably, one or more main swing arms are provided.

[0012] Preferably, two main swing arms are provided and are arranged in an A shape. The upper parts of the two main swing arms are respectively connected to the vehicle fixing frame through main rotating shafts, and the lower parts of the two main swing arms are coaxially hinged to the cross shaft.

[0013] Preferably, an auxiliary beam is fixedly connected between the two main swing arms.

[0014] Advantages of the present utility model

[0015] The present utility model is reasonably and novelly designed, and is convenient and effective to use.

[0016] When cleaning a panel (taking a photovoltaic panel as an example), the vehicle lifts this structure to a height suitable for the photovoltaic panel. Under the action of gravity, the brush assembly maintains an angle parallel to the photovoltaic panel. Under the action of the self-weight of the brush assembly, the bottom of the supporting wheel is in the same plane as the actual working surface of the brush assembly. The brush assembly always maintains a certain pressure between the brush assembly and the photovoltaic panel. At the same time, under the support of the floating support mechanism, the pressure between the brush assembly and the photovoltaic panel will not be too large. The brush assembly can adapt to the relative undulation between the photovoltaic panel and the ground, always maintain the distance between the brush assembly and the photovoltaic panel, and always maintain a certain pressure between the brush and the panel surface, so as to achieve self-adaptive adjustment and relatively stable pressure, thereby enabling the brush assembly to have a good cleaning effect.

[0017] The entire brush adjusting device can rotate around the main rotating shaft. The main swing arm supports all the weight of the brush assembly and plays a role in connecting the brush assembly and the vehicle. Description of the drawings
