Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of posture adjustment, and in particular to a method for detecting and adjusting the operating posture of a photovoltaic sweeper. Background Art
[0002] Existing photovoltaic panel cleaning robots typically consist of a housing with drive wheels mounted on the top and bottom to control the robot's path. Stop wheels are located on the outside of the housing, perpendicular to the drive wheels and in contact with the sides of the photovoltaic panel's outer frame. However, the robot may tilt during movement due to factors such as inconsistent drive wheel speeds, installation defects of the photovoltaic panels, or wheel slippage caused by rain or snow.
[0003] The Chinese patent with announcement number CN118550310A discloses a method for posture monitoring and adaptive deviation correction of a photovoltaic module cleaning robot. The present invention uses an intelligent recognition method, utilizes motor current data and applies a random forest model, so that the robot can accurately judge its operating status, such as climbing or crossing obstacles. And based on the robot's operating status and the offset distance in the walking direction between the two sensors, the robot's upper and lower motor speeds are adjusted to control the speed of the walking wheels in a stable operating state to quickly correct the robot's deviation from the posture. This adaptive deviation correction operation is only performed when the robot is running smoothly, ensuring the high efficiency and stability of the robot during the cleaning process. By combining sensor detection data and the real-time operating status of the robot, the present invention allows the robot to accurately calculate the deflection displacement and adjust it in real time, providing a safe and reliable solution for photovoltaic cleaning.
[0004] However, the above-mentioned disclosed solution has the following shortcomings: the above-mentioned device uses an algorithm control method to adjust and control the posture of the cleaning robot. In actual use, the above-mentioned device does not specify the specific sensor position, so errors are likely to occur during the posture detection process, causing the cleaning robot to judge the wrong posture as a normal posture.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-4 The present invention is described in further detail.
[0033] Example 1
[0034] like Figure 1-Figure 4 As shown, in this embodiment, in order to solve the existing problems, the present invention discloses a method for detecting and adjusting the operating posture of a photovoltaic sweeper, comprising a base 1 and a photovoltaic panel 2 arranged obliquely on the top thereof, a housing 3 slidingly provided on the surface of the photovoltaic panel 2, a bottom driving component 5 connected to the bottom of the housing 3, a top driving component 6 connected to the top of the housing 3, and a control module 4 connected to the side of the housing 3 away from the photovoltaic panel 2;
[0035] A sensing component 10 is connected to the top of the shell 3 , and a rotating motor 8 is connected to the side of the shell 3 close to the photovoltaic panel 2 . A cleaning roller 9 is connected to the output end of the rotating motor 8 , and bristles are provided on the outer arc surface of the cleaning roller 9 .
[0036] The bottom drive component 5 includes a bottom drive housing 501 connected to the bottom of the housing 3. The bottom drive housing 501 is provided with a plurality of drive motors. The vertical output end of the drive motor is fixedly connected to a bottom abutting wheel 502. The horizontal output end of the drive motor is fixedly connected to a bottom drive wheel 503. The bottom drive wheel 503 contacts the surface of the photovoltaic panel 2, and the bottom abutting wheel 502 contacts the side of the photovoltaic panel 2.
[0037] Furthermore, the top drive component 6 includes a top drive shell 601 connected to the top of the shell 3, and several drive motors are provided in the top drive shell 601. The vertical output end of the drive motor is fixedly connected to the top abutment wheel 602, and the horizontal output end of the drive motor is fixedly connected to the top drive wheel 603. The top drive wheel 603 contacts the surface of the photovoltaic panel 2, and the top abutment wheel 602 contacts the side of the photovoltaic panel 2.
[0038] The control module 4 is connected to the driving motor in the top driving housing 601 and the control module 4 is connected to the driving motor in the bottom driving housing 501;
[0039] Furthermore, the outer arc surfaces of the top abutting wheel 602 and the top driving wheel 603 are provided with an anti-slip layer, and the outer arc surfaces of the bottom abutting wheel 502 and the bottom driving wheel 503 are provided with an anti-slip layer;
[0040] Specifically, the side of the housing 3 is rotatably connected to a support wheel 7 , and the support wheel 7 is in contact with the photovoltaic panel 2 .
[0041] The specific working principle is: this device can be used to clean the surface of the photovoltaic panel 2, thereby improving the working efficiency of the photovoltaic panel 2. When this device is in use, the shell 3 may tilt relative to the photovoltaic panel 2. When the shell 3 tilts, since the shell 3 and the edge of the photovoltaic panel 2 are not in a parallel state, the distance between the sensor bracket 1001 on both sides of the shell 3 and the side of the photovoltaic panel 2 is also different. At this time, the ultrasonic sensor components 1002 on both sides of the sensor bracket 1001 can judge in real time the distance between the two sides of the sensor bracket 1001 and the photovoltaic panel 2 in the current state.
[0042] When the spacing distance signals received by the sensors on both sides are transmitted to the control module 4, the control module 4 will compare the signals on both sides. When the spacing difference between the sensor signals on both sides is less than a certain range, it means that the shell 3 is working in a normal posture and does not need to be adjusted. When the spacing difference between the sensors on both sides exceeds a certain range, the top and bottom drive motors stop working.
[0043] By judging the information received by the sensor, when the distance between the left sensor bracket and the photovoltaic panel 2 is smaller than the distance between the right sensor bracket and the photovoltaic panel 2, the bottom drive wheel 503 stops rotating, and the top drive wheel 603 runs alone under the drive motor, so that the shell 3 returns to its normal posture. When the difference in the distance between the sensor brackets on both sides returns to a certain range, the top and bottom drive motors work simultaneously again.
[0044] When the distance between the left sensor bracket and the photovoltaic panel 2 is greater than the distance between the right sensor bracket and the photovoltaic panel 2, the top drive wheel 603 stops rotating, and the bottom drive wheel 503 runs alone under the drive motor, so that the shell 3 returns to its normal posture. When the distance difference between the sensor brackets on both sides returns to a certain range, the top and bottom drive motors work simultaneously again.
[0045] The structure of the cleaning roller 9 can clean the surface of the photovoltaic panel 2 when the shell 3 passes over the surface of the photovoltaic panel 2, thereby ensuring that the photovoltaic panel 2 can always be in a state of high photoelectric conversion efficiency.
[0046] Example 2
[0047] like Figure 1-Figure 4 As shown, in order to solve the existing problems, based on the same concept as the above-mentioned embodiment 1, the method for detecting the operating posture and adjustment of the photovoltaic sweeper further includes: the sensing component 10 includes a sensor bracket 1001 connected to the top of the housing 3, and a plurality of ultrasonic sensor assemblies 1002 distributed at equal intervals are respectively provided at both ends of the sensor bracket 1001;
[0048] Furthermore, the ultrasonic sensor assembly 1002 includes an ultrasonic transmitter and an ultrasonic receiver, both of which are oriented toward the side of the photovoltaic panel 2 , and the ultrasonic transmitter and the ultrasonic receiver are communicatively connected to the control module 4 .
[0049] The specific working principle is as follows: This device can automatically clean the photovoltaic panel 2. Compared to traditional devices, this device has an automatic posture correction function to prevent it from getting stuck during long-term use. Furthermore, the long, rectangular shape of the housing 3 reduces the amount of light that is blocked by the device, thus preventing it from affecting the normal working efficiency of the photovoltaic panel 2.
[0050] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
