Description
Technical Field
[0001] This invention relates to the field of photovoltaic cleaning robot technology, specifically a high-pressure nozzle mechanism for a photovoltaic cleaning robot with a telescopic adjustment structure. Background Technology
[0002] Photovoltaic cleaning robots, as automated equipment specifically designed for cleaning the surfaces of solar photovoltaic panels, demonstrate significant advantages in improving cleaning efficiency, ensuring power generation stability, and optimizing operation and maintenance management. Their core value lies in solving the pain points of traditional manual cleaning through technological means.
[0003] Among them, the Chinese patent application number "202321553140.2" discloses "A Photovoltaic Cleaning Robot with Correction Function," which is also an increasingly mature technology. It describes that "This utility model discloses a photovoltaic cleaning robot with correction function, including two induction switch assemblies, a photovoltaic cleaning robot body, several photovoltaic modules, and a control system. The two induction switch assemblies are respectively installed on the lower left and right ends of the photovoltaic cleaning robot body. The photovoltaic cleaning robot body is mounted on several photovoltaic modules. The induction switch assembly located on the left end of the photovoltaic cleaning robot body corresponds to several sensing blocks located on the left end face of the upper frame of the photovoltaic modules, and the induction switch assembly located on the right end of the photovoltaic cleaning robot body corresponds to several sensing blocks located on the right end face of the upper frame of the photovoltaic modules. Both induction switch assemblies are connected to the control system signal. This utility model's photovoltaic cleaning robot with correction function accurately detects and monitors the position of the left and right ends of the photovoltaic cleaning robot, and the induction switch assemblies and sensing blocks do not interfere with the movement of the photovoltaic cleaning robot, ensuring cleaning efficiency." In addition, it has the following disadvantages: 1) The high-pressure nozzle structure of traditional photovoltaic cleaning robots is usually not suitable for cleaning photovoltaic panels arranged in batches. It can also lead to instability in the high-pressure cleaning process of the photovoltaic panel surface. The cleaning height cannot be adjusted adaptively. This results in the inability to get the high-pressure water outlet close to the photovoltaic panel surface during subsequent cleaning. The photovoltaic panel has a generally low degree of flexibility in the high-pressure nozzle cleaning process, which is not conducive to the turning of the high-pressure nozzle, resulting in deviation when aiming the water spray to clean the photovoltaic panel. In addition, the direction of nozzle rotation cannot be changed during the extension and retraction of the high-pressure nozzle in order to adapt to the photovoltaic panel arrangement spacing in conventional technology. Furthermore, the nozzle switching process severely affects the subsequent conversion and cleaning efficiency of the photovoltaic panels, resulting in poor stability of the nozzle when adapted to other cleaning brushes, making it unsuitable for use with photovoltaic cleaning robots. Summary of the Invention
[0004] The purpose of this invention is to provide a high-pressure nozzle mechanism for a photovoltaic cleaning robot with a telescopic adjustment structure, which solves the above-mentioned shortcomings in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a high-pressure nozzle mechanism for a photovoltaic cleaning robot with a telescopic adjustment structure, comprising a support mechanism. The support mechanism includes a square frame supported by the ground. First access bases are respectively provided on the top two sides of the square frame. Vertical columns are installed on the first access bases, and a hydraulic lifting cylinder is provided at the top of each vertical column. A load-bearing mechanism is provided at the top of the hydraulic lifting cylinder, and a lifting mechanism is provided below the load-bearing mechanism. The lifting mechanism includes a pneumatic cylinder and a spray head. The pneumatic cylinder is connected to the spray head via an adjusting sleeve and an adapter sleeve.
[0006] Preferably, the lifting mechanism further includes a third access base disposed below the transverse support rod. The bottom of the third access base is provided with a U-shaped pad, and an electric lifting cylinder is installed on the U-shaped pad. The telescopic end of the electric lifting cylinder is connected to a linkage shaft, and a concave bracket is connected below the linkage shaft. The pneumatic cylinder is installed inside the concave bracket.
[0007] Preferably, the spray head is connected to the adapter sleeve via an L-shaped lifting bracket, the adapter sleeve is connected to the adjusting sleeve via a bushing, and the adjusting sleeve is fixed to the output end of the pneumatic cylinder.
[0008] Preferably, the vertical column sidewall is equipped with a load-bearing support bar, the top of the hydraulic lifting cylinder is provided with an adapter pad, and the load-bearing mechanism includes a top plate, a horizontal support rod, a triangular bracket and a connecting guide rod.
[0009] Preferably, the top of the square frame is provided with a lifting mechanism, which includes a water storage tank, a water pump and a configuration box, and the water outlet of the water pump is connected to the spray head through a pipe.
[0010] Preferably, a brush roller cleaning mechanism is provided on the side of the vertical column. The brush roller cleaning mechanism includes a cleaning brush, a drive motor and a first stepper motor. The surface of the cleaning brush is provided with brush strips.
[0011] Preferably, the brush roller cleaning mechanism further includes an arc-shaped cover located above the cleaning brush to prevent cleaning agent from splashing.
[0012] Preferably, the square frame is provided with a traction mechanism on its side, the traction mechanism including a buffer spring, an elastic buffer base, a second drive roller and a triangular side plate.
[0013] Preferably, the traction mechanism further includes a push cylinder, a small swing arm, a large swing arm, and a second stepper motor, used to adjust the horizontal position and angle of the spray head.
[0014] Preferably, the end of the traction mechanism is connected to an angle conversion mechanism, which includes a drive motor, a T-shaped bracket and a drive base, for realizing the rotational adjustment of the spray head.
[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a high-pressure nozzle mechanism for a photovoltaic cleaning robot with a telescopic adjustment structure. The mechanism utilizes a spray head and a suitable sleeve to adjust the flow of liquid through a regulating sleeve. An extended output end of a starting pressure cylinder, along with an extended output end of the adjusting sleeve, allows the L-shaped lifting bracket and spray head to deliver pressurized cleaning agent. A pneumatic pressure cylinder output end adjusts the distance between the spray head and the photovoltaic panel, ensuring that water pressure is not lost due to excessive distance. An angle-adjusting motor and a rotating sleeve allow for changes in the cleaning direction. The concave bracket rotates gradually, and the starting pressure cylinder body changes the direction of the spray head relative to the photovoltaic panel. After the drive motor is powered on, the direction of the small swing arm at one end of the control drive base will change. The small swing arm and the concave bracket support structure are clamped together, which changes the actual cleaning water output direction of the high-pressure nozzle. In addition, the distance between the brush roller and the photovoltaic panel surface can be adjusted from the overall perspective. After the cylinder of the push cylinder extends and retracts, the specific assembly frame will be adjusted downwards. The angle of one end of the small swing arm is changed. The H-shaped bracket is used to change the rotation direction of the corresponding drive roller shaft. The triangular side plate makes the elastic support of the elastic buffer base connected between the bases share the weight, so as to control the shaking arc of the overall cleaning structure during operation and avoid excessive shaking amplitude. When the stepper motor is powered on, it drives the output shaft to rotate. The brush strip and specific cleaning brush come into contact with the surface of the photovoltaic panel that needs to be cleaned. One end of the brush strip enables the corresponding cleaning brush to rotate, and the brush contacts the photovoltaic panel. Combined with the liftable spray head, the process of multiple rolling wipes imitates the process of manual scrubbing, which improves the cleaning efficiency of the photovoltaic panel surface.

[0046] When the second stepper motor 698 is powered on, it changes the rotation direction of the large swing arm 697, triggering the corresponding cleaning structure. This allows for easy adjustment of the extension and retraction of the high-pressure nozzle, bringing the specific nozzle structure closer to the photovoltaic panel.
[0047] Example 8 Based on Embodiment 1, this embodiment provides a high-pressure nozzle mechanism for a photovoltaic cleaning robot with a telescopic adjustment structure. The angle conversion mechanism 7 includes a transmission base 71 disposed at the bottom of the second swing arm 697. A T-shaped bracket 72 is disposed at the bottom of the transmission base 71. In order to connect and install the second swing arm 697 to the bottom of the transmission base 71, a fifth access base 73 is disposed at the bottom of the T-shaped bracket 72. A motor base 74 is disposed on the fifth access base 73. A transmission motor 75 is disposed at the top of the motor base 74. The output end of the transmission motor 75 is hinged to the surface of the bottom motor base 74.
[0048] The drive motor 75 is installed on the motor base 74. After being powered on, the high-pressure nozzle structure can be adjusted to fit against the surface of the photovoltaic panel to complete the convenient cleaning of the photovoltaic panel. By adjusting the angle, the motor is powered on to drive the nozzle to rotate in the direction of water spray. The height is adjusted by uniformly replacing the length of the cylinder extension of the pneumatic cylinder 48. At this time, the user needs to change the nozzle direction and control the surface transformation of the concave bracket 47. At this time, the user starts the lifting.
[0049] Example 9 This embodiment provides a method for using a high-pressure nozzle mechanism for a photovoltaic cleaning robot with a telescopic adjustment structure, including the following steps: Step 1: Replace the photovoltaic module to be cleaned and place it in the cleaning area; adjust the high-pressure nozzle to be close to the photovoltaic panel so that the spray nozzle 495 can spray out. According to the corresponding matching sleeve 493, the cylinder body of the pneumatic cylinder 48 is activated to extend and retract, driving the output of the adjusting sleeve 491, and changing the surface of the spray head 495 to contact the photovoltaic panel according to the matching sleeve 493. The position and height of the high-pressure nozzle are adjusted by utilizing the extension and retraction of the cylinder body of the pneumatic cylinder 48. At this time, the user needs to change the direction of the nozzle and control the surface transformation of the concave bracket 47. The user then starts the lifting and lowering process, and the motor is energized according to the corresponding angle adjustment. The height of the concave bracket 47 is changed on the surface of the rotating sleeve. Similarly, at this time, the direction of the output end of the pneumatic cylinder 48 will control the lifting base 49 to move downward. Based on the L-shaped lifting bracket 494, the actual spray intensity of the spray head 495 is changed. Through the specific L-shaped lifting bracket 494, the water outlet structure is installed. At this time, the liquid will be discharged from the position of the spray head 495. The lifting linkage shaft 44 is affected by the extension and retraction of the cylinder body of the electric lifting cylinder 43. The output end extends, which adjusts the axial position of the lower linkage shaft 44 and the overall position of the concave bracket 47. Adjust the water outlet direction of the spray head 495, and install and fix the first step motor 29 based on the second access base 21 and support frame 28. After powering on, the connecting crossbar 27 and its brush strip 25 will rotate. Multiple cleaning brushes 24 will clean the photovoltaic panel that has just been sprayed with cleaning agent, brushing away the residue on the photovoltaic panel. During the high-speed rotation, the cleaning agent is loaded to complete the brushing. It is supported by the trapezoidal bracket 291. In order to avoid liquid splashing when the brush roller is swung, the arc-shaped cover 292 is set to block the cleaning agent when swung. Step 2: Source of the liquid, prepare the appropriate cleaning agent; Personnel only need to add cleaning water into the water storage tank 51. Based on the power supply of the water pump 54, liquid is generated and pumped into the appropriate matching cylinder 493, so that there is enough water and cleaning agent, which is then pressurized and sprayed out from the spray head 495. Step 3: Install the drive motor 75 based on the motor base 74; At this time, the transmission base 71 is switched by adjusting one end of the transmission motor 75, and the second stepper motor 698 is energized, which drives the small swing arm 696 to tilt downward. Then, the hinge bracket 695 and the push cylinder 694 are energized and pulled to control the assembly frame 692 to move downward. At this time, in order to reduce the shaking of the H-shaped bracket 68 during the downward movement, the vibration during the operation of the machine can be buffered and offset by the elastic buffer base 63. The fourth access base 61 is moved downward. The hinge loading of the second drive roller shaft 66 pulls the triangular side plate 67 to connect with the drive roller shaft 66 for hinge. The surface of the elastic buffer base 63 is used to achieve buffering based on one end of the specific H-shaped bracket 68. Based on the hinge of the fourth access base 61 and the second drive roller shaft 66, the axial rotation of the fourth access base 61 is controlled.
