Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic panel cleaning control devices, and in particular to an automatic angle adjustment mechanism suitable for photovoltaic panel cleaning devices. Background Art
[0002] The surface of photovoltaic panels is mostly made of glass. If the photovoltaic panels are hit, rubbed violently or otherwise physically contacted during daily use or surface cleaning, it is easy to cause damage such as glass breakage and scratches, which in turn affects the power generation efficiency of the photovoltaic panels. Photovoltaic panels are often arranged outdoors, where the ground is undulating, and the cleaning device's carrier will inevitably shake during movement. At the same time, the heights and planes of adjacent photovoltaic panels are often not absolutely uniform. Therefore, how to reduce the damage to photovoltaic panels caused by cleaning devices when cleaning photovoltaic panels is a technical problem that needs to be solved urgently.
[0003] The technical problem to be solved by this application is how to achieve relative stability of the contact pressure of the cleaning device on the photovoltaic panel by adjusting the position of the cleaning device relative to the carrier in real time, while achieving effective cleaning and reducing the damage to the photovoltaic panel caused by the shaking of the carrier or the unevenness of the photovoltaic panel. Utility Model Content

By controlling the adjustment mechanism in real time, the position of the photovoltaic panel cleaning device is controlled to achieve the purpose of controlling the contact pressure of the cleaning device on the photovoltaic panel to be relatively stable.
[0005] The technical solution of the utility model is as follows:

The photovoltaic panel cleaning device may also be equipped with an ultrasonic sensor, an infrared sensor or other distance sensor, and the central controller can adjust the spatial form of the photovoltaic panel cleaning device in real time by calculating the distance data detected by the above sensors.
[0013] Control principle of regulating mechanism:
[0014] The central controller sets an initial position for the oil cylinder or electric cylinder (for example, the electric cylinder is set to the initial position when it is at its shortest);
[0015] Set the pressure sensor reference value of the photovoltaic panel cleaning device;
[0016] A mathematical model is established in the control program. The positions of the first fixed ear, the second fixed ear, and the third fixed ear represent a fixed structure which can be considered to be fixed. The three hinged fixed points of the first fixed ear, the second fixed ear, and the third fixed ear are collinear and fixed.
[0017] The four fixed ears, the five fixed ears and the six fixed ears on the photovoltaic panel cleaning device are collinear and controlled by three electric cylinders or oil cylinders through length control;
[0018] The control program presets the reference coordinate system, with a fixed ear point as the origin, the line connecting the fixed ear 1, fixed ear 2, and fixed ear 3 as the X-axis, and the straight line perpendicular to the line connecting the fixed ear 1, fixed ear 2, and fixed ear 3 and passing through a fixed ear point as the Y-axis;
[0019] In the initial state, the three points of fixed ear 4, fixed ear 5 and fixed ear 6 have an initial starting point coordinate; the central controller compares the information returned by the pressure sensor with the set reference value to obtain the coordinates that the two points of fixed ear 4 and fixed ear 6 need to reach;
[0020] The coordinates of the fixed ears 5 and 6 are calculated based on the coordinates of the fixed ears 4 and 6, and the movement distances of the fixed ears 4, 5 and 6 are obtained. The extension or shortening length and speed of each electric cylinder or oil cylinder are calculated in combination with the movement time.
[0021] The control instructions are sent to the sub-controllers of each electric cylinder or hydraulic cylinder, and each sub-controller controls each electric cylinder or hydraulic cylinder to realize movement;
[0022] Repeated detection, comparison, calculation and execution processes form real-time and continuous control.
[0023] Beneficial effects of the utility model
[0024] The utility model has a reasonable structural design, is convenient and effective to use, and uses three oil cylinders or electric cylinders to form two trapezoidal shapes to form a plane stable structure. The utility model uses a central controller combined with a pressure sensor to control the extension and retraction of the adjustment rods I, II, and III in real time, thereby controlling the position of the photovoltaic panel cleaning device to achieve the purpose of controlling the contact pressure of the cleaning device on the photovoltaic panel to be relatively stable.
[0025] In three-dimensional space, the movement of objects can be classified as having three coordinate axes, a total of 6 directions, front and back (Y axis), left and right (X axis), up and down (Z axis). The present application is to limit the flexible movement of the photovoltaic panel cleaning device in the two-dimensional plane and limit the Y-axis movement, and use the extension and retraction of adjustment rods I, II, and III to control the precise movement of the object in the plane formed by the X-axis and Z-axis.
