Description

Technical Field

[0001] This invention belongs to the field of photovoltaic cleaning technology, specifically a descaling mechanism suitable for photovoltaic modules in complex terrain. Background Technology

[0002] In northern regions, the Gobi Desert is vast, relatively flat, and receives ample sunshine, making it suitable for the concentrated and continuous installation of photovoltaic panels. However, the Gobi Desert has a harsh climate with low annual precipitation and strong winds and sandstorms. Due to environmental factors, dust, fallen leaves, bird droppings, and frost and snow formed by the low temperatures can easily accumulate on the surface of the photovoltaic panels, thereby reducing the utilization rate of photovoltaic power generation and causing some energy loss. Therefore, it is necessary to clean the photovoltaic panels regularly to improve power generation.

[0003] Chinese invention patent CN117081500A discloses a solar photovoltaic panel cleaning machine. This cleaning machine achieves passive cleaning of the surface of solar photovoltaic panels based on the combination of a moving mechanism, a position adjustment mechanism, and a cleaning device, effectively saving manufacturing costs. The position adjustment mechanism adjusts the spatial position of the cleaning device to make the cleaning mechanism contact the surface of the solar photovoltaic panel.

[0004] In existing technologies, the cleaning mechanism is usually installed on a vehicle. However, the roads in the Gobi Desert are rugged, and the vehicle will bump during the journey, causing the cleaning mechanism to vibrate. This results in poor cleaning effect and excessive pressure on the photovoltaic modules, causing damage to the photovoltaic modules. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A scale removal mechanism for photovoltaic modules suitable for complex terrain includes a water tank containing multiple equidistant floats. Each float has a rod fixedly connected to its upper surface. The ends of the rods in the same row are connected to a connecting frame. The connecting frame is a frame structure that fits around the water tank. A pair of sliding platforms are connected to the bottom of the connecting frame. The sliding platforms are staggered below the water tank, and each platform has an installation platform. A cleaning mechanism is mounted on the installation platform. The cleaning mechanism includes a connecting plate with a pair of first and second sweeping discs.

[0008] Preferably, a set of cantilever arms are symmetrically arranged on the front surface of the connecting plate. The cantilever arms are arranged in parallel vertically. An end plate is slidably connected to the cantilever arm. A first pneumatic telescopic rod is hinged to the end plate. The first pneumatic telescopic rod is located between the cantilever arms. The other end of the first pneumatic telescopic rod is fixed to the connecting plate by a hinge plate. A first sweeping disc is installed on the lower surface of the end plate.

[0009] Preferably, a crank arm is fixedly connected to the rear surface of the connecting plate, and a hinge seat is assembled on the lower front surface of the crank arm. A second pneumatic telescopic rod and a support arm are connected through the hinge seat, and the ends of the second pneumatic telescopic rod and the support arm are rotatably connected to the second sweeping disc.

[0010] Preferably, a sleeve is welded to the front end of the crank arm, and a motor is installed at the upper end of the sleeve. The drive shaft of the motor passes through the sleeve through the embedded bearing, and the drive shaft of the motor is fixedly connected to the hinge seat after passing through the sleeve.

[0011] Preferably, a driver is provided in the center of the upper surface of the first and second sweeping discs, and a turntable is provided on the lower surface of the first and second sweeping discs. The upper surface of the turntable is connected to the driver, and a brush is fixedly connected to the turntable.

[0012] Preferably, a turntable is installed in the center of the connecting plate, and a support elbow is fixed on the turntable, which is fixed to the mounting platform by bolts.

[0013] Preferably, a connecting frame is provided on the upper part of the inside of the water tank, and multiple limiting brackets are welded at equal intervals on the connecting frame. Multiple waist holes are opened on the limiting brackets, and the opening position of the waist holes corresponds to the position of each cue stick. The cue stick passes through the waist holes and connects to the connecting frame.

[0014] Preferably, a crossbar is provided on the outside of the connecting frame for connection. The crossbar connects multiple connecting frames into a whole. The length of the connecting frame is greater than the height of the water tank. The float moves with the rise and fall of the water level in the tank. When the float moves with the rise and fall, the connecting frame is stably adjusted outside the water tank by the ball rod.

[0015] Preferably, the lower surface of the connecting frame is provided with a hook, and the slide is suspended on the hook and fixed by welding.

[0016] Preferably, the mounting platform is fixedly connected to the slider on the slide, and the mounting platform is inclined with an acute angle.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this invention, the water tank contains multiple floats arranged at equal intervals, which are connected to a frame-type connecting frame outside the water tank via ball rods. The floats float as the water level in the tank rises and falls, thereby driving the connecting frame to adjust its height stably. This design allows the cleaning mechanism to adaptively adjust its height according to the state of the water tank, which helps maintain the stability of the entire cleaning mechanism under different working conditions. The multiple floats arranged at equal intervals can provide more uniform support and adjustment force to the connecting frame, ensuring the stability of the connecting frame and the connected cleaning mechanism in all directions. Furthermore, the multiple floats arranged at equal intervals can provide more uniform support and adjustment force to the connecting frame, ensuring the stability of the connecting frame and the connected cleaning mechanism in all directions.

[0018] (2) This invention includes a pair of first and second sweeping discs. Sweeping discs with different positions and structures can more comprehensively clean different areas of the photovoltaic surface, improving the cleaning coverage area and effect. When the circular sweeping disc rotates, its edge can form a continuous annular cleaning area, avoiding cleaning blind spots at the corners of the rectangular structure, and can more efficiently cover the photovoltaic panel. Furthermore, the sweeping disc is installed on the end plate connected by a cantilever and is controlled by the first pneumatic telescopic rod, which can flexibly adjust the first sweeping disc according to the actual situation of the photovoltaic panel surface, such as uneven areas or areas with different degrees of dirt. The position and angle are adjusted to better fit the surface of the photovoltaic panel and improve cleaning quality. Furthermore, the second sweeping disc is connected to the connecting plate through a structure including a curved arm, a hinged seat, a second pneumatic telescopic rod, and a support arm. The motor drives the front end of the curved arm through the sleeve and hinged seat, making the second sweeping disc flexible in terms of angle and position adjustment. It can work in conjunction with the first sweeping disc to optimize the cleaning effect. The upper surface of the first and second sweeping discs is equipped with a driver, and the lower surface is equipped with a turntable and a brush. The driver drives the turntable to rotate, so that the brush can efficiently clean the photovoltaic panel and ensure the efficient execution of the cleaning action. Attached Figure Description

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0031] like Figure 1 The diagram shown is a schematic diagram of a photovoltaic module surface descaling cleaning mechanism suitable for complex terrain in this embodiment. The photovoltaic cleaning mechanism in this embodiment includes a water tank 100 and a cleaning mechanism 200 assembled on the water tank.

[0032] exist Figure 2 and Figure 3 In this system, the water tank 100 serves as the foundation of the entire cleaning mechanism. It contains multiple equidistant floats 101 arranged in a regular pattern, maintaining a uniform spacing to ensure a consistent response to changes in the liquid level within the tank. Each float 101 has a rod 1011 fixedly connected to its upper surface. These rods are made of a sturdy yet lightweight material, such as high-strength aluminum alloy, ensuring sufficient strength to withstand the forces exerted by the connecting components while reducing overall weight. The ends of the rods 1011 in the same row are connected to a connecting frame 104. The connecting frame 104 is designed as a frame structure, providing good stability and a tight fit around the water tank 100, offering protection and support. The bottom of the connecting frame 104 is connected to a pair of sliding tables 105, which are high-precision linear slides to ensure smoothness and accuracy during subsequent movements. To ensure accuracy, the lower surface of the connecting frame 104 is equipped with hooks 1041, which are made through precision casting and possess high strength and toughness. The slide table 105 is suspended on the hooks 1041 and fixed by welding. The welding process employs advanced automated welding technology to ensure consistent and robust welding quality. The slide tables 105 are staggered below the water tank 100. This staggered layout provides a larger support range within a limited space, enhancing the stability of the entire structure. An installation platform 1051 is provided on the slide table 105. The installation platform 1051 is tightly fixed to the slider on the slide table 105 using high-strength bolts, ensuring no loosening during movement. Furthermore, the installation platform 1051 is inclined at an acute angle. This inclination angle design was determined through multiple experiments and simulations, ensuring stable installation of the cleaning mechanism while better adapting to the tilt angle of the photovoltaic panel, thus improving the cleaning effect. exist Figure 3Furthermore, a connecting frame 102 is provided on the upper part of the water tank 100. The connecting frame 102 is firmly fixed to the inner wall of the water tank 100 by welding. Multiple limiting brackets 103 are welded equidistantly on the connecting frame 102. The limiting brackets 103 are made of high-quality channel steel and are galvanized to improve their corrosion resistance. Multiple slots are provided on the limiting brackets 103. The positions of the slots correspond precisely to the positions of the ball rods 1011. The ball rods 1011 pass through the slots and connect to the connecting frame 104. This design can limit the movement of the ball rods 1011, ensuring their stable movement in the vertical direction, without causing excessive obstruction to the rise and fall of the float 101 with the liquid level. A crossbar is provided on the outside of the frame 104 for connection. The crossbar is made of high-strength I-beams and is firmly connected to the connecting frame 104 by welding. The crossbar connects multiple connecting frames 104 into a whole, forming a stable frame structure, which greatly enhances the stability and integrity of the entire mechanism. The length of the connecting frame 104 is greater than the height of the water tank 100. This design allows the connecting frame to have enough space outside the water tank for adjustment. The float ball 101 floats with the rise and fall of the water level in the water tank 100. When the float ball floats, the ball rod 1011 drives the connecting frame 104 to be stably adjusted outside the water tank 100, thereby realizing the height adjustment of the cleaning mechanism 200 installed on the connecting frame.

[0033] It should be noted that in this embodiment, the water in the water tank 100 is adjusted to salt water according to actual parameters to increase buoyancy, and the galvanized layer of the float 101 is used for corrosion resistance.

[0034] exist Figure 4 , Figure 5 as well as Figure 8In this embodiment, the cleaning mechanism 200 is mounted on the installation platform 1051 and is the core component for realizing the photovoltaic panel cleaning function. The cleaning mechanism 200 includes a connecting plate 201, which serves as the connecting hub of the entire cleaning mechanism and has high strength and rigidity. A set of cantilever arms 202 are symmetrically arranged on the front surface of the connecting plate 201. The cantilever arms 202 in the same set are arranged vertically and parallel to each other. The cantilever arms 202 are made of high-quality steel and have undergone fine processing and heat treatment to improve their load-bearing capacity and fatigue resistance. An end plate 204 is slidably connected to the cantilever arm 202. The end plate 204 and the cantilever arm 202 are connected by a high-precision linear guide rail to ensure that the end plate 204 is in the cantilever arm 202. To ensure smooth and precise sliding, a first pneumatic telescopic rod 203 is hinged to the end plate 204. The first pneumatic telescopic rod 203 is located between the cantilever arms 202 in the same group, and its other end is fixed to the connecting plate 201 via a hinge plate. This hinged connection allows the first pneumatic telescopic rod 203 to flexibly adjust the position of the end plate 204 during operation, thereby achieving precise control of the cleaning position of the first sweeping disc 2041. The first sweeping disc 2041 is installed on the lower surface of the end plate 204 and is made of wear-resistant and corrosion-resistant polymer material. Its surface is designed with a special texture to enhance friction with the photovoltaic panel surface and improve cleaning efficiency. exist Figure 9 In this embodiment, a curved arm 205 is fixedly connected to the rear surface of the connecting plate 201. The curved arm 205 is firmly connected to the connecting plate 201 through a high-strength welding process. A hinge seat is mounted on the lower front surface of the curved arm 205. This hinge seat is made of high-strength alloy steel and is precision machined to ensure the accuracy and reliability of its connection with other components. A second pneumatic telescopic rod 206 and a support arm 207 are connected through the hinge seat. The ends of the second pneumatic telescopic rod 206 and the support arm 207 are rotatably connected to the second sweeping disc 208. The second pneumatic telescopic rod 206 can flexibly adjust the angle of the second sweeping disc 208 according to the actual cleaning needs. The support arm 207 plays a role in assisting support and stabilizing the second sweeping disc 208, ensuring its smooth operation during the working process. The front end of the articulated boom 205 is welded with a sleeve, and a motor is installed at the upper end of the sleeve. This motor is a high-torque, low-energy-consumption special motor to meet the power requirements of the sweeping work. The sleeve is embedded with a bearing, which is a high-precision, low-friction rolling bearing. The drive shaft of the motor passes through the sleeve and is fixedly connected to the hinge seat. This connection method allows the motor to efficiently transmit power to the hinge seat, thereby causing the hinge seat to rotate, which in turn controls the rotation of the second pneumatic telescopic boom 206 and the support arm 207, so as to extend the working area of ​​the second sweeping disc 208. This is suitable for the complex conditions and rugged roads in the Gobi Desert, where vehicles cannot approach the photovoltaic panels well. Through the above structure, the effective working length of the second sweeping disc 208 is extended.

[0035] exist Figure 6 and Figure 7 In this design, a driver 209 is centrally located on the upper surface of the first sweeping disc 2041 and the second sweeping disc 208. The driver 209 employs an advanced intelligent drive control system that automatically adjusts the rotation speed and cleaning intensity of the sweeping discs based on the degree of dirt on the photovoltaic panel surface. A turntable is located on the lower surface of both the first and second sweeping discs. The turntable is made of lightweight and high-strength composite material, and its surface undergoes special treatment to enhance the connection strength with the brushes. The upper surface of the turntable is connected to the driver 209, achieving efficient power transmission through a high-precision coupling. Brushes are fixedly connected to the turntable. The brushes are made of high-quality bristles with good elasticity and wear resistance, effectively removing dust, dirt, and other debris from the photovoltaic panel surface.

[0036] It is worth noting that the first sweeping disc 2041 and the second sweeping disc 208 in this embodiment are circular rather than rectangular, mainly for the following practical reasons: When the circular sweeping disc rotates, its edges can form a continuous annular cleaning area, avoiding cleaning blind spots at the corners of the rectangular structure, and can cover the photovoltaic panels more efficiently; During the rotation of the circular structure, the force on each point is relatively balanced, and the wear is more uniform, which can extend the service life of the sweeping disc and the drive components; while the corners of the rectangle are prone to excessive wear due to concentrated force during rotation; When the circular sweeping disc rotates, the centrifugal force is evenly distributed, the operation is more stable, and the equipment vibration is reduced; When the rectangular structure rotates, the center of gravity changes periodically, which may cause the equipment to shake, affecting the cleaning effect and stability.

[0037] exist Figure 1 In the middle, a turntable 2011 is centrally mounted on the connecting plate 201. The turntable 2011 can rotate 360 ​​degrees, providing flexibility for the cleaning mechanism 200 to clean in different directions. A support elbow 2012 is fixed on the turntable 2011. The support elbow 2012 is fixed to the mounting platform 105 with bolts. The bolts are high-strength anti-loosening bolts to ensure the reliability of the connection and prevent the connection from loosening due to vibration or other reasons during the cleaning process.

[0038] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
