Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module cleaning technology, specifically, to a photovoltaic module cleaning device. Background Technology
[0002] Cleaning devices 1a play a crucial role in the maintenance of photovoltaic modules, significantly improving cleaning efficiency through automated operation. Currently, such as Figure 1 As shown, the mainstream cleaning device 1a relies on its own battery 1b for power. However, when the cleaning device 1a is deployed in high-latitude, frigid regions, it faces a series of challenges. In winter, temperatures in these areas can drop to extremely low levels of -40°C, while in summer they can soar to extreme highs of +60°C. Under such extreme temperature conditions, the performance of the battery 1b is severely affected, leading to a significant increase in power consumption. This power consumption not only reduces the cleaning device 1a's endurance but may also prevent it from completing its intended cleaning tasks, thus seriously affecting the efficiency and effectiveness of the cleaning work. Utility Model Content
[0003] The purpose of this invention is to provide a cleaning device for photovoltaic modules. By improving the structure of the cleaning device, the traditional battery-powered method is replaced, thereby improving the adaptability of the cleaning device to extreme temperature conditions.
[0004] To achieve the above objectives, this utility model provides a cleaning device for photovoltaic modules. The cleaning device for photovoltaic modules includes a cleaning main component, a slide rail beam, and a current collector electrically connected to the cleaning main component. The slide rail beam extends along the moving direction of the cleaning main component and is slidably adapted to the current collector. The cleaning main component is also provided with a connector, which is adapted to the current collector to drive the current collector to slide along the slide rail beam.
[0005] The slide rail beam is equipped with a conductive element, which is used to form an electrical connection with an external power source; the current collector is equipped with an electrical connection end, which abuts against the conductive element during the sliding process of the current collector.
[0006] By adopting the solution in this application, the current collector can move along the slide rail beam and the main cleaning component. A conductive element is also provided inside the slide rail beam, and the conductive element extends in the same direction as the slide rail beam. During the sliding process of the current collector relative to the slide rail beam, it can always keep in contact with the conductive element, thereby realizing the method of powering the main cleaning component through an external power source, which improves the adaptability of the cleaning device to extreme temperature conditions.
[0007] Optionally, a portion of the current collector is located inside the slide rail beam, and a portion is located outside the slide rail beam, with the connector adapted to the portion of the current collector located outside the slide rail beam.
[0008] This method avoids damage to the slide rail beam and ensures its structural strength.
[0009] Optionally, the portion of the current collector located outside the slide rail beam is defined as the adapter end;
[0010] One of the adapter end and the connector is provided with a slot, and the other is provided with a lever that can be inserted into the slot. The slot includes a first directional stop wall, which abuts against the lever in the direction of movement of the cleaning main component.
[0011] This method enables the current collector and the main cleaning components to move in tandem.
[0012] Optionally, the slot further includes two second-direction stop walls, which are arranged opposite each other along the height direction, and the lever is located between the two second-direction stop walls. This further improves the adaptability to photovoltaic modules of different heights.
[0013] Optionally, the adapter end has two slots, which are located on both sides of the adapter end along the moving direction of the cleaning main component.
[0014] Optionally, the slide rail beam has a box-shaped structure, and its inner wall is provided with a mounting groove extending in the same direction as the beam, which is used to insert the conductive component. This facilitates the installation, maintenance, and replacement of the conductive component.
[0015] Optionally, the end of the slide rail beam is further provided with a conductive connector. Part of the conductive connector abuts against the conductive component, and part is used for electrical connection to an external power source. The conductive connector has a sheet-like structure and extends outward from the slide rail beam. The outward-facing conductive connector facilitates electrical connection to an external power source, simplifying manual operation.
[0016] Optionally, the current collector has a first limiting surface and a second limiting surface, the first limiting surface and the second limiting surface being distributed relative to each other along the height direction;
[0017] The slide rail beam has a third limiting surface and a fourth limiting surface arranged opposite to each other along the height direction, and the third limiting surface and the fourth limiting surface are located between the first limiting surface and the second limiting surface;
[0018] In the height direction, the first limiting surface presses against the third limiting surface, and the fourth limiting surface presses against the second limiting surface.
[0019] In this way, the current collector can be limited in the height direction to ensure that the current collector abuts against the conductive parts.
[0020] Optionally, the slide rail beam is made of insulating material. This improves the safety of the cleaning device.
[0021] Optionally, the system also includes a support frame disposed below the photovoltaic module. This allows for support of the slide rail beam while simultaneously utilizing the space originally occupied by the photovoltaic module, thus improving the space utilization rate of the cleaning device.

Detailed Implementation
[0033] This invention provides a cleaning device for photovoltaic modules. By improving the structure of the cleaning device, the traditional battery-powered method is replaced, thereby improving the adaptability of the cleaning device to extreme temperature conditions.
[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.
[0036] To address the problems described in the background technology, the conventional approach is to increase battery capacity. Theoretically, a larger battery capacity can store more electrical energy, thus mitigating, to some extent, the adverse effects of extreme temperatures on battery performance. However, increasing battery capacity means a corresponding increase in the battery's physical volume, which in turn inevitably leads to increased battery weight. For cleaning devices, photovoltaic modules have strict requirements on their load-bearing capacity, because excessive load not only increases the robot's energy consumption but may also affect its movement flexibility and stability, and could even lead to mechanical failure.
[0037] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of an existing cleaning device; Figure 2 This is a partially enlarged schematic diagram of the structure of the cleaning device in an embodiment of this utility model; Figure 3 This is a schematic diagram of the slide rail beam; Figure 4 This is a schematic diagram of the current collector; Figure 5 This is a schematic diagram of the cleaning device in an embodiment of this utility model.
[0038] This utility model provides a cleaning device for photovoltaic modules. The cleaning device includes a cleaning main component 2, a slide rail beam 3, and a current collector 5 electrically connected to the cleaning main component 2. The cleaning main component 2 is used to clean the photovoltaic modules. The cleaning main component 2 is provided with a power supply connection terminal 522, which is physically connected to and electrically connected to the current collector 5.
[0039] The slide rail beam 3 extends along the moving direction of the cleaning main component 2. Specifically, the photovoltaic module includes several photovoltaic panels 1 connected in sequence. The cleaning main component 2 moves in the arrangement direction of the photovoltaic panels 1 to clean the surface of the photovoltaic panels 1. In the extending direction of the slide rail beam 3, the slide rail beam 3 covers the moving length of the cleaning main component 2, thereby ensuring that the current collector 5 can always be electrically connected to the external power source while the cleaning main component 2 is cleaning the photovoltaic panels 1.
[0040] Specifically, the slide rail beam 3 is fitted with a current collector 5, and the main cleaning component 2 is also equipped with a connector that fits into the current collector 5 to drive the current collector 5 to slide along the slide rail beam 3. The slide rail beam 3 is equipped with a conductive element for forming an electrical connection with an external power source; the current collector 5 is equipped with an electrical connection end 522, which abuts against the conductive element during the sliding process of the current collector 5.
[0041] By adopting the solution in this application, the current collector 5 can move along the slide rail beam 3 and the main cleaning component 2 in a follow-up manner. The slide rail beam 3 is also provided with a conductive element that extends in the same direction as the slide rail beam 3. During the sliding process of the current collector 5 relative to the slide rail beam 3, it can always keep in contact with the conductive element, thereby realizing the method of supplying power to the main cleaning component 2 through an external power source, which improves the adaptability of the cleaning device to extreme temperature conditions.
[0042] In the example shown, part of the current collector 5 is located inside the slide rail beam 3, and part is located outside the slide rail beam 3. The connector is adapted to the part of the current collector 5 located outside the slide rail beam 3. The part located inside the slide rail beam 3 is defined as the conductive end 52, and the part located outside the slide rail beam 3 is defined as the adapter end 53. A sliding adapter section 51 is also provided in the height direction to connect the conductive end 52 and the adapter end 53. The connector is adapted to the adapter end 53, thereby avoiding damage to the slide rail beam 3 and ensuring the structural strength of the slide rail beam 3. Of course, the connecting end also passes through the slide rail beam 3 and is adapted to the conductive end 52. Using a method equivalent to the aforementioned adaptation method is also within the scope of protection of this patent, as long as it can realize the follow-up movement of the current collector 5 and the cleaning main component 2.
[0043] In one specific embodiment, one of the adapter end 53 and the connector is provided with a slot 532, and the other is provided with a lever 21 that can be inserted into the slot 532. The slot 532 can form a bidirectional stop engagement with the lever 21 in the moving direction of the cleaning main body component 2. That is, when the cleaning main body moves forward or backward in its moving direction, the lever 21 can be adapted to the slot 532 to drive the current collector 5 to follow the movement of the cleaning main body component 2.
[0044] In the example shown, the adapter end 53 has two slots 532, which are located on both sides of the adapter end 53 along the moving direction of the cleaning main component 2. Each slot 532 includes a first directional stop wall 532a, which abuts against the lever 21 in the moving direction of the cleaning main component 2. In this implementation, the first directional stop wall 532a is the bottom wall of the corresponding slot 532. The lever 21 is disposed in the cleaning main component 2, extending into the corresponding slot 532 and abutting against the bottom wall of the corresponding slot 532. Thus, when the cleaning main component 2 moves, the lever 21 can apply a pushing force to the bottom wall of the slot, thereby driving the current collector 5 to follow.
[0045] Of course, in addition to this method, the number of slots 532 can also be one. When the number of slots 532 is one, it can be set on the bottom surface of the adapter end 53. At this time, the first direction stop wall 532a is the two slot sidewalls of the slot 532, and the lever 21 is also one. It can be inserted into the slot 532 and pressed between the two first direction stop walls 532a. In addition, other equivalent adapter methods of slots 532 and lever 21 are also within the protection scope of this patent.
[0046] As an optional implementation of the aforementioned embodiment, in the example shown in the figure, the slot 532 further includes two second-direction stop walls 532b, which are arranged opposite each other along the height direction. The lever 21 is located between the two second-direction stop walls 532b. In the figure, the second-direction stop walls 532b are slot sidewalls connected to the bottom wall of the slot. The distance between the two slot sidewalls is greater than the size of the lever 21, thereby allowing the lever 21 to move between the two slot sidewalls. In this case, the two second-direction stop walls 532b only limit the extreme positions of the lever 21's movement in the height direction. The distance between the two second-direction stop walls 532b can be set according to the height difference of the photovoltaic modules to be cleaned. This method can further improve the adaptability to photovoltaic modules of different heights.
[0047] In the above embodiment, the slide rail beam 3 has a box-shaped structure, and its inner wall is provided with mounting grooves 331 extending in the same direction as the box. The mounting grooves 331 are used to insert conductive components. Specifically, the box-shaped structure includes a top beam wall 31 and a bottom beam wall 32 distributed along the height direction, and side beam walls 33 connecting the top beam wall 31 and the bottom beam wall 32. The mounting grooves 331 are all provided in the side beam walls 33, and the mounting grooves 331 are provided with openings. The conductive components are plate-shaped structures, inserted into the mounting grooves 331, and part of them can be exposed through the openings. The conductive end 52 is provided with an electrical connection end 522, which abuts against the corresponding conductive component and forms an electrical connection. The conductive component is made of a conductive material, such as a copper sheet. Of course, the mounting grooves 331 can be provided not only in the side beam walls 33, but also in the top beam walls 31 and the bottom beam walls 32, which can be selected by those skilled in the art.
[0048] In the example shown, the end of the slide rail beam 3 is also provided with a conductive connector 34. Part of the conductive connector 34 abuts against a conductive element, and part is used for electrical connection to an external power source. The conductive connector 34 has a sheet-like structure and extends outward from the slide rail beam 3. The outward-facing conductive connector 34 facilitates electrical connection to an external power source, making manual operation easier. Alternatively, the conductive connector 34 can be composed of a conductive element, with both ends of the conductive element extending from the ends of the slide rail beam 3 to form an electrical connection with an external power source.
[0049] In one specific implementation, the bottom beam wall 32 has a sliding opening 321, and the sliding adapter section 51 is located within the sliding opening 321. The slide rail beam 3 also has two folded edges 35, the top ends of which are fixedly connected to the sliding opening 321, and the bottom ends are folded outward to form a flange 36, which is parallel to the bottom beam wall 32. The slide rail beam 3 and the folded edges 35 are integrally formed structures, or they can be separate assembly structures.
[0050] The dimensions between the two folded edges 35 are consistent with the dimensions of the sliding adapter end 53, and can abut against the side wall of the corresponding sliding adapter section 51, thereby limiting the sliding adapter section 51 and preventing it from shifting in the direction perpendicular to the extension of the slide rail beam 3 during movement.
[0051] The bottom beam wall 32 has a third limiting surface 322, which is the inner wall surface of the bottom beam wall 32. The flange portion 36 has a fourth limiting surface 361. The third limiting surface 322 and the fourth limiting surface 361 are distributed relative to each other along the height direction. The fourth limiting surface 361 is parallel to the third limiting surface 322 and is located on the side of the flange portion 36 opposite to the third limiting surface 322 in the height direction.
[0052] The current collector 5 has a first limiting surface 521 and a second limiting surface 531 arranged opposite each other along the height direction. The first limiting surface 521 is the lower surface of the conductive end 52, and the second limiting surface 531 is the upper surface of the adapter end 53. The first limiting surface 521 and the second limiting surface 531 are located between the first limiting surface 521 and the second limiting surface 531. In the height direction, the first limiting surface 521 presses against the third limiting surface 322, and the fourth limiting surface 361 presses against the second limiting surface 531. In this way, the current collector 5 can be limited in the height direction, ensuring that the current collector 5 abuts against the conductive element.
[0053] In the above embodiment, the slide rail beam 3 is made of insulating material. This improves the safety of the cleaning device.
[0054] Specifically, the cleaning device in this application also includes a support frame 4, which is disposed on the lower side of the photovoltaic module. This allows the support frame 4 to utilize the space originally occupied by the photovoltaic module while simultaneously supporting the slide rail beam 3, thus improving the space utilization rate of the cleaning device.
[0055] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
