DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0035] The utility model is a splicable suspended single-roller photovoltaic panel cleaning machine, which is mainly used for automatic and rapid cleaning of the surface of solar photovoltaic panels. It has a foldable anti-fall mechanism, a splicable structure, an automatic tensioning mechanism, and a one-button adjustment function for adjusting the device posture to cross obstacles. It can be applied to solar photovoltaic panels installed at various tilt angles. It can clean an entire row of photovoltaic panels in one operation with high cleaning efficiency. Specifically, the cleaning machine of the utility model can be implemented as follows:

[0036] Example 1

[0037] Please refer to Figure 1 、 Figure 4-a and Figure 4-b , Figure 1 The overall structure diagram of the photovoltaic panel cleaning machine of this embodiment is as follows. Since the photovoltaic panels are installed to match the local sunshine time range and irradiation angle range, they will be set at a certain tilt angle to obtain the best light receiving effect. When the cleaning machine is working, the walking mechanisms at both ends may not be in the same vertical plane, causing the equipment to be at a certain tilt angle on the photovoltaic panel surface and the vertical plane. In order to prevent the machine from continuing to walk after reaching the edge of the photovoltaic panel and causing it to fall, the photovoltaic panel cleaning machine of the utility model has an anti-fall mechanism 7, such as Figure 1 As shown, the anti-drop mechanism 7 can be divided into multiple groups and arranged on the left and right sides of the upper and lower ends of the cleaning machine. Preferably, four groups are arranged. No matter how the equipment is tilted, there will be no hidden danger of falling. When the equipment moves and cleans, the anti-drop mechanism 7 runs synchronously with the movement of the equipment to ensure that the anti-drop function can be achieved when moving in two directions.

[0038] As an optional embodiment, the anti-fall mechanism 7 can be composed of a support member, an adjustment arm, a rotating shaft 20, a blocking arm 21 and a signal sensor 22. The support member can be set to Figure 4-a and Figure 4-b The support wheel 17 shown can also be replaced by other support members that can be in rolling contact or sliding contact, for example, ball contact support, slider contact support, etc., which can be selected according to needs and fall within the protection scope of the present invention. The stop arm 21 is hinged to the housing of the cleaning machine, and is preferably arranged on the inner wall of the housing. The signal sensor 22 is arranged at a corresponding position on the other end of the cleaning machine housing away from the hinge of the stop arm 21, and is also preferably arranged on the inner wall of the cleaning machine housing, for sensing the position of the stop arm 21 through signal changes to determine whether the machine has reached the edge. The stop arm 21 is connected to the adjustment arm through the rotating shaft 20, and the end of the adjustment arm is connected to the support wheel 17, and the support wheel 17 is used to support the anti-fall mechanism 7 to operate on the surface of the photovoltaic panel; equipment During cleaning, the support wheel 17 runs on the photovoltaic panel. At this time, the barrier arm 21 and the signal sensor 22 are away, and the equipment moves normally for cleaning. When the equipment moves to the edge of the photovoltaic panel, the support wheel 17 will first move out of the range of the photovoltaic panel, thereby losing the support of the photovoltaic panel and falling, driving the rotating shaft 20 of the adjusting arm to rotate, thereby rotating the barrier arm 21 and approaching the signal sensor 22 to trigger the signal. After receiving the sensing signal, the equipment will stop moving and cleaning. At this time, the equipment can only be controlled to move in the opposite direction for cleaning, thereby realizing the function of preventing falling; this structure can realize the anti-fall function when the cleaning machine is at any tilt angle, so that the photovoltaic panel cleaning machine can perform cleaning work safely and stably on various photovoltaic panel surfaces, thereby greatly improving the versatility and stability of the equipment.

[0039] As a preferred embodiment, a set of anti-drop mechanisms 7 are installed on each of the four corners of the device to ensure that the device can play an anti-drop role no matter what posture it is in. The adjustment arm and support wheel 17 of the anti-drop mechanism 7 can be arranged on the outside of the cleaning machine housing, and the falling position is detected by mechanical movement when the equipment moves to the edge of the photovoltaic panel, while the signal sensor 22 and the barrier arm 21 are inside the housing to prevent the influence of rain, snow and water mist during cleaning, which may cause inaccurate detection results. It has high safety and strong durability. Preferably, the signal sensor 22 adopts an inductive metal sensor to sense the position of the barrier arm 21 through the change of the inductive signal, which has lower installation difficulty, good shock resistance and strong anti-interference ability. The model of the signal sensor 22 can be selected from: Shanghai Industry LJ18A3-8-Z / AX, Omron E2E-X10ME2-Z, etc. Those skilled in the art can choose from existing sensors as needed and directly apply them to the present utility model.

[0040] Example 2

[0041] Based on the implementation scheme of Example 1, in order to avoid the accidental damage caused by the collision between the anti-drop mechanism 7 and other objects in the environment during handling or transportation in a non-cleaning state, the anti-drop mechanism 7 is set as a foldable structure in this embodiment. Figure 5-a and Figure 5-b The adjusting arm of the present invention includes a first adjusting arm 18 connected to the supporting wheel 17 and a second adjusting arm 19 hinged to the first adjusting arm 18. The second adjusting arm 19 is connected to the blocking arm 21 through a rotating shaft 20. An adjusting arm rotating shaft 24 is connected between the first adjusting arm 18 and the second adjusting arm 19. The adjusting arm rotating shaft 24 is used to support the first adjusting arm 18 to rotate around the connection point with the second adjusting arm 19; this structure realizes that when the machine is in a non-cleaning state, the first adjusting arm 18 can be operated to rotate around the adjusting arm rotating shaft 24 at the connection point with the second adjusting arm 19, and the first adjusting arm 18 is folded and retracted, thereby avoiding partial exposure of the mechanism and collision with the environment, causing damage, and reducing the probability of collision.

[0042] As a preferred embodiment, in order to fix the position of the adjustment arm in the folded and unfolded state, the second adjustment arm 19 is equipped with an indexing pin 23, and the first adjustment arm 18 is provided with a first positioning hole 181 and a second positioning hole 182 for the indexing pin 23 to extend into. Figure 5-a As shown), the indexing pin 23 is inserted into the first positioning hole 181. At this time, the first adjustment arm 18 and the second adjustment arm 19 are in a straight line, so that the anti-drop mechanism 7 works normally. When the machine is in a non-cleaning state, the indexing pin 23 can be pulled up to exit the first positioning hole 181, and then the first adjustment arm 18 can be rotated and folded to a position perpendicular to the second adjustment arm 19 (as shown). Figure 5-b As shown), the indexing pin 23 is inserted into the second positioning hole 182 to fix the positions of the first adjustment arm 18 and the second adjustment arm 19, thereby preventing the adjustment arms from accidentally deploying and colliding during vibration and the like, thereby improving safety.

[0043] Example 3

[0044] This embodiment is a solution further implemented on the basis of embodiment 1, in order to solve the problem that the adjacent horizontal edges of some photovoltaic panels are not in the same plane when installed, and there is a height difference, and the cleaning machine cannot cross the height difference in this case, resulting in the cleaning being unable to move forward normally and slipping on the spot, so as to avoid the consequences of causing wear of the drive wheel 15, burnout of the motor, prolonged cleaning time, reduced cleaning efficiency, etc., please refer to Figure 7-a 、 Figure 7-b 、 Figure 7-cIn this embodiment, the cleaning machine has a remote one-button posture adjustment function through the separate setting and control of the upper drive mechanism 1 and the lower drive mechanism 2, so that the height difference of the photovoltaic panel can be crossed by adjusting the posture of the equipment. Specifically, in this embodiment, the driving mechanism of the cleaning machine is divided into an upper driving mechanism 1 and a lower driving mechanism 2, and the two driving mechanisms can be controlled to start and stop separately, and a hanging wheel assembly 16 is configured to ensure that the equipment remains suspended during the process, and is used to be hung on the upper side of the photovoltaic panel. The hanging wheel assembly 16 has a first hanging wheel 161 and a second hanging wheel 162 distributed on both sides; preferably, the cleaning machine can be equipped with a remote control operation, and the remote control sends a remote signal to control it, so as to realize one-button operation. The remote control can be set with a built-in program to control the upper driving mechanism 1 and the lower driving mechanism 2 to cross obstacles with one button. When the equipment encounters an uneven end face of the photovoltaic panel (such as Figure 7-a As shown), press the adjustment button in the corresponding direction, the upper drive mechanism 1 stops, the lower drive mechanism 2 moves forward, the device posture tilts, and the upper first hanging wheel 161 rises (as shown Figure 7-b As shown), at this time, release the button, the upper and lower drive mechanisms 2 operate normally, keep the current tilt posture and move forward, after the first hanging wheel 161 passes the convex position of the photovoltaic panel, control the machine posture to adjust in the opposite direction, press the adjustment button in the opposite direction to the previous one, the lower drive mechanism 2 moves backward, the upper drive mechanism 1 remains stationary, and the device posture returns to normal (as shown). Figure 7-c As shown, the second hanging wheel 162 is raised above the raised photovoltaic panel, and the adjustment button is released. The drive mechanism then operates normally and moves forward for cleaning. This structure realizes the equipment's one-button posture adjustment function, which is simple to operate and effective, greatly improving obstacle passability during cleaning and ensuring the normal progress of the cleaning task.

[0045] Example 4

[0046] This embodiment is a further implementation based on the embodiment 1. To ensure the stable operation of the drive mechanism, please refer to Figure 1-Figure 2In this embodiment, the drive mechanism includes a drive motor 10, the motor shaft of which is connected to an active synchronous pulley 11. The active synchronous pulley 11 is connected to a driven synchronous pulley 13 via a synchronous belt 12. The driven synchronous pulley 13 is connected to a drive wheel 15 via a drive shaft 14. The device can be provided with a remote control to set the start and stop of the drive motor 10. By starting the drive motor 10 to rotate counterclockwise and clockwise respectively, the active synchronous pulley 11 is driven to rotate. The motion is transmitted to the driven synchronous pulley 13 via the synchronous belt 12. The driven synchronous pulley 13 drives the drive wheel 15 to rotate via the drive shaft 14, thereby moving the cleaning machine forward or backward. When reverse movement is required, the drive motors 10 are controlled to rotate in the opposite direction. When the pause button is pressed, all drive motors 10 immediately stop, the movement and scrubbing action stops, and the device is paused. Preferably, during cleaning, a speed adjustment button can be set to be pressed, and the device travel speed is cyclically switched between low, medium, and high by adjusting the rotation speed of the drive motor 10 to meet the cleaning needs of different levels of contamination.

[0047] In order to ensure that the synchronous belt 12 can still be tensioned and prevented from loosening when it is deformed due to aging during use, thereby ensuring the long-term normal operation of the equipment, an adaptive tensioning device can be provided on the synchronous belt 12. The adaptive tensioning device is used to keep the synchronous belt 12 in a certain tensioned state on the active synchronous pulley 11 and the driven synchronous pulley 13. Even if the synchronous belt 12 is deformed due to aging, the tensioning force can be adjusted so that it can always achieve a good transmission effect.

[0048] Example 5

[0049] This embodiment is a further implementation scheme of the adaptive tensioning device in Example 4. In order to solve the problems that the tensioning device in the prior art usually adopts mechanical fixed tensioning, the tensioning force is difficult to control, the tensioning effect is poor, and the effect is lost as the synchronous belt 12 is deformed during use, and frequent adjustment and maintenance are required, this embodiment provides a further solution of the adaptive tensioning device. Please refer to Figure 3, is a structural schematic diagram of the adaptive tensioning device of this embodiment, which includes a smooth idler wheel 25 in contact with the synchronous belt 12, and the smooth idler wheel 25 is used to apply pressure to the synchronous belt 12 to tension it. The smooth idler wheel 25 is connected to a sliding tensioning bracket 26, and the sliding tensioning bracket 26 moves synchronously with the smooth idler wheel 25. The end of the sliding tensioning bracket 26 away from the smooth idler wheel 25 is connected to a spring seat 28, and a part of the sliding tensioning bracket 26 extends into the spring seat 28. The spring 27 force applied by the spring 27 connected between the inner wall of the spring seat 28 and the sliding tensioning bracket 26 pushes the sliding tensioning bracket 26 and the spring seat 28 to cause relative displacement to achieve adjustment, and the spring seat 28 is fixedly connected to the cleaning machine. The sliding tensioning bracket 26 is also connected to a support that passes through the interior of the spring seat 28. The frame bolt, a hand-tightening nut 29 for installing the spring seat 28 and the sliding tensioning bracket 26 is connected between the bracket bolt and the spring seat 28. The hand-tightening nut 29 is threadedly connected to the bracket bolt. When the synchronous belt 12 is relaxed, the pre-tightening force of the spring 27 can make the bracket bolt and the spring seat 28 displace relative to each other, thereby pushing the sliding tensioning bracket 26 connected thereto to slide, so that the smooth idler wheel 25 presses the synchronous belt 12 to achieve tensioning force adjustment. In order to prevent the bracket bolt from driving the sliding tensioning bracket 26 to rotate together due to the threaded connection during adjustment instead of just displacing, a strip groove can be opened on the sliding tensioning bracket 26, and the guide bolt on the spring seat 28 can be inserted into the strip groove to limit the movement of the sliding tensioning bracket 26 to displacement, thereby better achieving tension adjustment of forward and backward movement.

[0050] The adaptive tensioning device of this embodiment is more effective than the prior art and is maintenance-free. When the synchronous belt 12 needs to be replaced, the operation is simpler than the existing mechanical fixed tensioning operation.

[0051] Example 6

[0052] This embodiment is based on the implementation scheme of Example 1. In order to better support the operation of the photovoltaic panel cleaning machine, please refer to Figure 1The cleaning machine is provided with a splicable frame 4, on which a water spray device 8 and a roller brush assembly 3 are installed. The roller brush assembly 3 includes a roller brush motor 9 located at the end and a cleaning roller brush 33 connected to the roller brush motor. The splicable frame 4 is also provided with an electronic control component 5 for controlling the start and stop of the motor and a battery 6 for power supply. The battery 6 is electrically connected to the electronic control component 5. The electronic control component 5 is connected to all electrical devices through wires and other connection methods, and is used to control the operation of the electrical devices by starting and stopping, such as the drive motor 10 of the drive mechanism, the signal sensor 22, etc. The specific electronic control component can be Select from the existing technologies as needed and use them in the present invention; two sets of power displays can be set on the battery 6 and the overall shell of the device respectively to facilitate observation of the power of the device, and the water spray device 8 can be installed with a set of identical water spray mechanisms on both sides of the device. When cleaning, high-pressure water is connected and water is discharged from the mechanisms on both sides at the same time. When the device is turned on for mobile cleaning, the front water flow first flushes the photovoltaic panel. After the device moves to a water position, the roller brush brushes in the direction of movement, and the water flow on the other side flushes again, so that the cleaning effect is better. If water resources are limited in water-scarce areas, dry cleaning can also be performed without water.

[0053] Example 7

[0054] This embodiment can be implemented based on any one of the above embodiments 1-6 or a combination of any of the embodiments, in order to adapt to photovoltaic panels of different sizes and lengths, and avoid the need to design a dedicated size cleaning machine for each size of photovoltaic panel, such as Figure 8 As shown, in this embodiment, the cleaning machine is configured as a three-section splicable structure, namely a front section mechanism 30, a middle section mechanism 31 and a rear section mechanism 32. The front section mechanism 30 is provided with an electronic control component 5, a battery 6 and a lower drive mechanism 2, and the rear section mechanism 32 is provided with an upper drive mechanism 1. The roller brush assembly 3 is installed across the front section mechanism 30, the middle section mechanism 31 and the rear section mechanism 32, wherein the roller brush motor 9 can be installed in the front section mechanism 30, and the cleaning roller brush 33 can be installed on the middle section mechanism 31; the modularly designed middle section mechanism 31 of different lengths can be replaced by a quick-disassembly splicing connection structure to quickly extend or shorten the length of the cleanable section to adapt to the length of the photovoltaic panel to be cleaned. The splicable connection includes a quick-disassembly connection of the water pipe and a quick-disassembly connection of the power line connector, and a corresponding splicing mechanism can be designed to quickly splice and disassemble the three sections of the mechanism. This structure allows the middle section mechanism 31 to be quickly replaced, so that the same set of equipment can be used to clean photovoltaic panels of different sizes, effectively saving equipment investment costs.

[0055] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
