Description

Photovoltaic modules, as the core part of the photovoltaic power generation system, provide continuous green power for people's lives and industrial production by absorbing solar radiation energy and converting it into electrical energy. However, the operating efficiency of photovoltaic modules is closely related to the amount of solar radiation it receives. Snowfall in winter is an inevitable natural phenomenon. Once the surface of photovoltaic modules is covered with snow, it will seriously affect its light reception and electrical energy conversion efficiency, resulting in a decrease in power generation. In addition, the melting of snow may bring moisture and dirt, which will cause secondary pollution and potential damage to photovoltaic modules.

[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0037] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0038] With the transformation of the global energy structure and the rapid development of renewable energy, photovoltaic power generation, as a clean and renewable energy source, has been widely used around the world. Photovoltaic modules, as the core part of the photovoltaic power generation system, provide continuous green power for people's lives and industrial production by absorbing solar radiation energy and converting it into electrical energy. However, the operating efficiency of photovoltaic modules is closely related to the amount of solar radiation they receive. In winter, snowfall is an inevitable natural phenomenon. Once the surface of photovoltaic modules is covered with snow, it will seriously affect its light reception and electrical energy conversion efficiency, resulting in a significant decrease in power generation. In addition, the melting of snow may bring moisture and dirt, which will cause secondary pollution and potential damage to photovoltaic modules.

[0039] At present, the snow removal problem of photovoltaic modules mostly relies on manual removal, which uses snow removal tools (such as shovels, brooms, etc.) to directly remove the snow on the photovoltaic modules. Usually, workers need to stand near the photovoltaic modules or use extended tools to clean them. The labor intensity is high and the efficiency is low, which makes it difficult to cope with large-scale snow removal needs; there are safety hazards when removing snow in mountainous areas with steep terrain; and the surface of photovoltaic modules may be damaged when using snow removal tools.

[0040] In addition, the snow removal devices or technologies for photovoltaic modules in the prior art also include the following types:

[0041] 1. Thermal snow removal: Install electric heating wires or heating plates on the surface or below the photovoltaic modules, and use electric current to heat the elements to generate heat to melt the snow. The melted snow then flows down the photovoltaic modules, achieving the purpose of snow removal. Although melting snow with heating elements can be automated, it consumes a lot of energy and may affect the power generation efficiency of photovoltaic modules; uneven heating may also cause local overheating of the modules and damage the modules.

[0042] 2. Vibration snow removal: Vibration devices are used to generate periodic vibrations. These vibrations can be mechanical or ultrasonic waves generated by piezoelectric materials. The vibrations act on the snow, causing it to separate from the surface of the photovoltaic module and fall off. The snow is removed by the vibration device, but the vibration may cause structural damage to the photovoltaic module; it is not effective in heavy snow or freezing conditions; the noise generated by the vibration may affect the surrounding environment.

[0043] 3. Snow removal with chemical snow removers: Spraying chemicals (such as salt, calcium chloride, etc.) onto the surface of snow to lower the freezing point of snow, accelerate the melting of snow, and reduce the adhesion of snow to photovoltaic modules. Using chemical substances to accelerate the melting of snow may cause corrosion to the surface materials of photovoltaic modules; chemical residues may pollute the environment; long-term use may increase maintenance costs.

[0044] 4. Pneumatic snow removal: Use high-pressure gas (such as air) to generate high-speed airflow through a nozzle to disperse or blow away the snow on the photovoltaic modules. This method removes the snow through the momentum of the airflow. Although the snow removal speed is fast by blowing away the snow with high-pressure airflow, the energy consumption is high; the airflow may cause damage to the surface of the photovoltaic modules; when used in areas with high wind speed, it may be affected by the external wind speed.

[0045] 5. Self-cleaning coating snow removal: Special materials, such as super-hydrophobic coating, are applied to the surface of photovoltaic modules to make it difficult for snow to adhere to the surface of the modules. When the weight of the snow exceeds the carrying capacity of the coating, the snow will slide off naturally. Although special materials can be applied to the surface of photovoltaic modules to reduce snow adhesion, the effect is limited in extreme weather conditions; the coating may degrade over time and requires regular maintenance and renewal.

[0046] Therefore, the inventor proposes a photovoltaic module snow removal device to solve the above problems.

[0047] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0048] Figure 1 A diagram showing the use status of the photovoltaic module snow removal device provided in the embodiment of the present application; Figure 2 A schematic diagram of the installation of the track provided in the embodiment of the present application; Figure 3 A schematic diagram of the structure of the track provided in the embodiment of the present application; Figure 4 A schematic diagram of the structure of a transmission chain provided in an embodiment of the present application; Figure 5 A schematic diagram of the connection structure between the transmission gear and the power gear provided in an embodiment of the present application; Figure 6 A schematic diagram of the structure of a drive system provided in an embodiment of the present application; Figure 7 A schematic diagram of the structure of a snowplow provided in an embodiment of the present application; Figure 8 A schematic cross-sectional structure diagram of a snowplow provided in an embodiment of the present application; Fig. 9 A schematic diagram of the structure of the pressure cotton block system provided in an embodiment of the present application; Fig.10 A schematic diagram of the structure of a support arm provided in an embodiment of the present application; Fig.11 This is a schematic diagram of the transmission rod installation structure provided in an embodiment of the present application.

[0049] Reference Figures 1 to 11 As shown, a photovoltaic assembly snow removal device provided in an embodiment of the present application includes: a track assembly 1, a drive system 2 and a snow removal vehicle 3;

[0050] The track assembly 1 includes two tracks 4 and a transmission chain 5 and a transmission wheel set 6 arranged inside the track 4. The track 4 is respectively mounted on the upper and lower ends of the beam of the photovoltaic support 7 and is fixedly connected to the photovoltaic support 7.

[0051] Specifically, two tracks 4 are fixed at the upper and lower ends of the beam of the photovoltaic support 7, and the snowplow 3 is driven to move on the surface of the photovoltaic module through the transmission chain 5 set inside the track 4. The transmission wheel group 6 is used to obtain power from the drive system 2 to drive the transmission chain 5 to rotate.

[0052] The driving system 2 includes a motor 8 and a driving assembly. The driving assembly is drivingly connected to the transmission wheel set 6 . The driving assembly is used to transmit the power of the motor 8 to the transmission wheel set 6 .

[0053] Specifically, the drive system 2 provides the original driving force for the entire snow removal device. The motor 8 is a servo motor 8, which has the characteristics of fast response speed and low vibration and noise. It can be remotely controlled by setting a communication module and preset control instructions. For example, the power line and control line of the servo motor 8 are connected to the corresponding ports of the controller, and the start, stop, forward and reverse rotation and speed of the motor 8 are managed by the preset control instructions. This is the application of the existing technology and is not specifically limited.

[0054] The snowplow 3 includes a vehicle body 10, a pressure cotton block system 11, a support arm 12 and a clamping plate 13. The pressure cotton block system 11 is arranged at the bottom of the vehicle body 10; the clamping plate 13 is arranged below the vehicle body 10 through the support arm 12; the clamping plate 13 is provided with a clamping tooth matching the transmission chain 5 at one end close to the transmission wheel group 6, and the clamping plate 13 is connected to the transmission chain 5 through the clamping tooth, so as to drive the snowplow 3 to move on the upper surface of the photovoltaic module through the transmission chain 5.

[0055] Specifically, the trolley body 10 is set on the upper surface of the photovoltaic module through the support arm 12, and the trolley body 10 is driven to move by the clamping plate 13 under the support arm 12 and the transmission chain 5. At the same time, the pressure cotton block system 11 abuts against the upper surface of the photovoltaic module to clean the snow by moving. The cotton block is soft and delicate, and will not scratch or damage the surface of the photovoltaic module during the cleaning process. The cotton block has strong water absorption and can effectively absorb moisture on the surface of the snow, helping to quickly clean the surface of the photovoltaic module, reducing residual water marks and affecting the efficiency of photovoltaic power generation.

[0056] The present application provides a photovoltaic module snow removal device, which drives a transmission chain 5 through a motor 8 to move a snowplow 3 along the upper surface of the photovoltaic module to clear the snow accumulated on the photovoltaic module; and the cleaning process relies on a pressure cotton block system 11 under the trolley body 10, which can effectively remove snow while protecting the surface of the photovoltaic module from mechanical damage caused by the snowplow 3 during movement.

[0057] In some embodiments, the track 4 is a rectangular box body with an opening on one side away from the beam; the box body includes a bottom shell 41 and an upper cover 42, and the bottom shell 41 and the upper cover 42 are fixed by screws.

[0058] Specifically, the track 4 can well protect the internal transmission chain 5 and transmission wheel set 6, reduce their erosion and damage from the harsh external environment, and extend their service life; the open side is to facilitate the engagement of the clamping plate 13 with the transmission chain 5, so that the rotation of the chain drives the trolley body 10 to move, and at the same time, the height of the trolley body 10 is limited by limiting the clamping plate 13 to prevent it from shaking up and down and affecting the snow clearing effect.

[0059] In some embodiments, the transmission wheel group 6 includes a power gear 61, multiple transmission gears 62 and a gear shaft 63 corresponding to the number of transmission gears 62; a first bearing fixing hole 43 is opened at the position of the track 4 corresponding to the transmission gear 62, and a first bearing 44 is arranged in the first bearing fixing hole 43. The upper and lower ends of the gear shaft 63 are respectively fixed to the inner shaft of the first bearing 44, and the transmission gear 62 is arranged between the first bearings 44 and fixedly connected to the gear shaft 63; the transmission gear 62 is meshed with the transmission chain 5; the power gear 61 is arranged above the transmission gear 62 at one end close to the drive system 2, and the power gear 61 is fixedly connected to the gear shaft 63, and the power gear 61 is used to obtain power from the drive component to drive the transmission chain 5 to rotate.

[0060] Specifically, the number of transmission gears 62 can be increased or decreased according to the length of the transmission chain 5 to ensure the smoothness and stability of the transmission chain 5 during rotation. After the power gear 61 obtains power from the drive system 2, it transmits power by meshing with the transmission gear 62, and the transmission gear 62 drives the transmission chain 5 to rotate, thereby realizing power transmission.

[0061] In some embodiments, the above-mentioned driving assembly includes a driving gear 91, a bevel gear 92, and a transmission rod 93. The driving gear 91 is fixedly connected to the rotating shaft of the motor 8; the transmission rod 93 is rotatably connected to the crossbeam of the photovoltaic bracket 7; the bevel gear 92 is fixed to the two ends of the transmission rod 93, and the bevel gear 92 at one end close to the motor 8 is respectively connected to the driving gear 91 and the transmission wheel group 6 at one side close to the motor 8, and the bevel gear 92 at one end away from the motor 8 is connected to the transmission wheel group 6 at the side away from the motor 8.

[0062] Specifically, the motor 8 drives the bevel gear 92 to rotate via the driving gear 91. Since the bevel gear 92 is fixedly connected to the transmission rod 93, the rotation of the bevel gear 92 on the motor 8 side will drive the transmission rod 93 and the bevel gear 92 at the other end of the transmission rod 93 to rotate together. At the same time, the bevel gear 92 is meshed with the power gear 61 in the transmission wheel group 6. Therefore, the motor 8 can drive the transmission chains 5 in the two tracks 4 to rotate together.

[0063] In some embodiments, a second bearing fixing hole 94 is opened on the crossbeam of the photovoltaic bracket 7, a second bearing 95 is arranged in the second bearing fixing hole 94, and the transmission rod 93 is passed through the bearing hole of the second bearing 95 and fixed to the inner shaft of the second bearing 95.

[0064] Specifically, the transmission rod 93 is passed through the crossbeam of the photovoltaic bracket 7. By opening a second bearing fixing hole 94 on the crossbeam of the photovoltaic bracket 7 and setting a bearing, the friction between the transmission rod 93 and the crossbeam of the photovoltaic bracket 7 can be effectively reduced, which reduces energy loss and improves mechanical transmission efficiency; reduces wear between the transmission rod 93 and the crossbeam, and increases the service life of the transmission rod 93 and the crossbeam. The bearing stably supports the rotation of the shaft and reduces the vibration and noise of the mechanical equipment.

[0065] In some embodiments, the pressure cotton block system 11 includes a pressure component, a fixed plate 112 and a sponge block 113; a receiving chamber 31 with an opening at the lower end is provided at the bottom of the trolley body 10, the pressure component is arranged in the receiving chamber 31, and the lower end of the pressure component passes through the receiving chamber 31 and is fixedly connected to the fixed plate 112; the fixed plate 112 and the sponge block 113 are detachably connected.

[0066] Specifically, the pressure component is used to provide pressure to the fixing plate 112 and the sponge block 113, so that the sponge block 113 can fit more closely to the photovoltaic surface and improve the snow clearing effect; the fixing plate 112 is connected to the sponge block 113 in a detachable manner by setting a card slot, and the fixing plate 112 and the sponge block 113 can also be fixed by plugging in by opening a groove at the bottom of the fixing plate 112 and a socket on the side.

[0067] In some embodiments, the pressure assembly includes a first spring 1111, a connecting rod 1112 and a clamping plate 1113; the diameter of the connecting rod 1112 is smaller than the diameter of the lower opening of the accommodating chamber 31; the clamping plate 1113 is fixed to the terminal end of the connecting rod 1112; the diameter of the clamping plate 1113 is larger than the diameter of the lower opening of the accommodating chamber 31 and the diameter of the first spring 1111, and is used to fix the first spring 1111 and the upper half of the connecting rod 1112 in the accommodating chamber 31; the first spring 1111 is sleeved on the upper end of the connecting rod 1112, the top end of the first spring 1111 abuts against the top plate of the accommodating chamber 31, and the bottom end of the first spring 1111 abuts against the upper surface of the clamping plate 1113.

[0068] Specifically, the clamping table 1113 can be fixed by using a nut and opening an external thread on the connecting rod 1112. The clamping table 1113 fixes the spring in the accommodating cavity 31 and connects the fixing plate 112 and the sponge block 113 to the trolley body 10. If there is no clamping table 1113, when the trolley body 10 is removed, the connecting rod 1112, the fixing plate 112 and the sponge block 113 will be separated from the trolley body 10. By setting a pressure component, pressure is provided to the sponge block 113 while providing a buffer. When the trolley body 10 vibrates, it will not have a significant impact on the sponge block 113, ensuring the stability of the sponge block 113 during the cleaning process, improving the snow removal efficiency, and ensuring the snow removal quality.

[0069] In some embodiments, the support arm 12 includes a first support plate 121, a second support plate 122 and a connecting arm 123, the upper end of the connecting arm 123 is fixed to the end of the first support plate 121 away from the snowplow 3, and the lower end is fixed to the end of the second support plate 122 away from the snowplow 3; the first support plate 121 is fixed to the trolley body 10, and the clamping plate 13 is fixed to the second support plate 122.

[0070] Specifically, the clamping plate 13 is fixed to one end of the second support plate 122 close to the transmission chain 5. At the same time, a clamping tooth is provided on one side of the clamping plate 13 close to the transmission chain 5. The clamping tooth engages with the transmission chain 5, so that the connection between the snowplow 3 and the transmission chain 5 is more stable.

[0071] In some embodiments, a sliding groove corresponding to the first support plate 121 is opened at one end of the above-mentioned trolley body 10 close to the support arm 12, and the first support plate 121 is arranged in the sliding groove; the length of the sliding groove is greater than the length of the first support plate 121, and a second spring 124 is fixed to one end of the first support plate 121 close to the trolley body 10, and the other end of the second spring 124 is fixed to the inner wall of the sliding groove away from the support arm 12.

[0072] Specifically, when installing the snowplow 3, the second spring 124 can be stretched and deformed by stretching the support arm 12, so that the clamping teeth of the clamping plate 13 are meshed with the transmission chain 5. By providing the second spring 124, the installation efficiency of the snowplow 3 is effectively improved. At the same time, after the installation is completed, the support arm 12 is tightened toward the vehicle through the spring stretching effect, ensuring that the clamping plate 13 and the transmission chain 5 always maintain tight positive meshing, avoiding the slippage of the gear and the chain due to loose meshing.

[0073] In some embodiments, the photovoltaic module snow removal device further includes: a snow removal plate 14, which is arranged on the top of the snow removal vehicle 3, and a T-shaped groove is provided on the top of the snow removal vehicle 3. A slider matching the T-shaped groove is provided at the bottom of the snow removal plate 14, and the snow removal plate 14 is plugged and fixed to the snow removal vehicle 3.

[0074] Specifically, when the amount of snow is large, the snow removal board 14 can effectively push the snow on the surface of the photovoltaic module to fall to both sides, preventing the snow from covering the trolley and falling onto the cleaned photovoltaic modules, which increases the difficulty of snow removal. At the same time, the detachable design effectively reduces the time and cost of replacing and repairing the snow removal board 14.

[0075] Those skilled in the art will easily conceive of other implementations of the present application after considering the specification and practicing the technical solutions disclosed herein.
