Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0036] Photovoltaic power stations use photovoltaic modules to convert solar energy into electricity, which is then connected to the power grid to transmit this energy. Some photovoltaic stations are located in mountainous areas where rain and snow are common. Snow easily accumulates on the panels, affecting their photoelectric conversion efficiency and leading to reduced power generation.

[0037] To address the problem of snow accumulation on photovoltaic panels, existing automatic snow removal systems feature large-scale snow-moving devices, such as rolling bristles. These devices also incorporate sensors that receive light signals and convert them into electrical signals. When the electrical signals change, the device identifies snow accumulation and triggers snow removal, driving the snow-moving device, such as a rolling bristle, to move relative to the surface of the photovoltaic panel, thereby removing the snow.

[0038] However, the above-mentioned device is in direct contact with the surface of the photovoltaic module, which can easily cause scratches or crushing to the photovoltaic module. In the case of power rationing, it can easily lead to changes in electrical signals. Even in the absence of snow, it may trigger the above-mentioned device to start and stop frequently, further aggravating the wear of the photovoltaic module.

[0039] In view of this, an embodiment of the present application provides a fixed-type automatic snow removal tool, comprising: a snow removal component, a detection component, and a control component; the snow removal component includes an air jet component and a heating component, the air jet component being connected to the heating component and being arranged toward the photovoltaic component; the detection component includes a first detection component for detecting the light intensity on the surface of the photovoltaic component, a second detection component for detecting the theoretical power and available power of the photovoltaic component, and a third detection component for detecting the electrical quantity of the photovoltaic component; the air jet component, the heating component, the first detection component, the second detection component, and the third detection component are all electrically connected to the control component. By comparing the difference between the theoretical power and available power of the photovoltaic component with a second preset value, it is determined whether a power limit is in effect. When the difference between the theoretical power and available power is greater than the second preset value, i.e., power limit is in effect, neither the air jet component nor the heating component is activated, thereby reducing the risk of frequent starts and stops caused by false triggering of the device. When the difference between theoretical power and available power is less than or equal to a second preset value, indicating no power curtailment, if the light intensity is greater than or equal to a first preset value and the electrical load is less than or equal to a third preset value, the air jet assembly and the heating assembly are activated. The heating assembly moves relative to the surface of the photovoltaic panel to heat and melt the ice, while the air jet assembly sprays air toward the surface of the photovoltaic panel to remove snow without directly releasing it from the panel surface, thus reducing scratches or marks on the panel surface. This device thus reduces the frequent starting and stopping of the snow removal assembly and minimizes damage to the photovoltaic panel surface.

[0040] Combine Figures 1 to 6 The fixed component automatic snow removal tool of the present application is described with specific embodiments.

[0041] The embodiment of the present application provides a fixed-type automatic snow removal tool, comprising: a snow removal component 100, a detection component 200, and a control component 300. The snow removal component 100 includes an air jet component 110 and a heating component 120. The air jet component 110 is connected to the heating component 120 and is disposed toward the photovoltaic component. The air jet component 110 is configured to move relative to the surface of the photovoltaic component to remove snow from the surface of the photovoltaic component. The heating component 120 moves relative to the surface of the photovoltaic component to heat the surface of the photovoltaic component.

[0042] The detection assembly 200 includes a first detection member 210, a second detection member 220, and a third detection member 230. The first detection member 210 is used to detect the light intensity on the surface of the photovoltaic module, the second detection member 220 is used to detect the theoretical power and available power of the photovoltaic module, and the third detection member 230 is used to detect the electrical quantity of the photovoltaic module.

[0043] The jetting assembly 110, the heating assembly 120, the first detecting member 210, the second detecting member 220 and the third detecting member 230 are all electrically connected to the control assembly 300;

[0044] The control component 300 is configured to control the jet component 110 and the heating component 120 to start when it is detected that the light intensity is greater than or equal to a first preset value, the difference between the theoretical power and the available power of the photovoltaic component is less than or equal to a second preset value, and the electrical quantity is less than or equal to a third preset value.

[0045] In a specific implementation, the air jet assembly 110 is positioned toward the surface of the photovoltaic module and is configured to spray air toward the surface of the photovoltaic module. The heating assembly 120 is configured to heat the surface of the photovoltaic module to melt snow accumulated on the surface. The specific structure of the heating assembly 120 is not limited in this embodiment of the application. For example, the heating element of the heating assembly 120 is a high-temperature heating wire.

[0046] The jet assembly 110 moves relative to the surface of the photovoltaic panel to remove snow from the surface of the photovoltaic panel. To achieve the movement of the jet assembly 110, the jet assembly 110 can be driven by a drone to move relative to the surface of the photovoltaic panel, or the jet assembly 110 can be moved relative to the surface of the photovoltaic panel using the mobile assembly 140 and the track assembly 400, which is not limited in this embodiment of the present application.

[0047] The first detection component 210 is used to detect the light intensity on the surface of the photovoltaic module. The embodiment of the present application does not limit the specific structure of the first detection component 210. For example, due to the high humidity in the outdoor environment, the water vapor content in the air increases, which can easily cause a large amount of light to be absorbed, scattered or weakened by the water vapor, thereby affecting the sensor reception effect. Therefore, the first detection component 210 is a photosensor with waterproof performance and high transmittance. This sensor is IP67 grade and can cope with humid environments, ensuring that it can still work normally in a high humidity environment. The first detection component 210 converts the light radiation signal into an electrical signal and transmits the electrical signal to the control component 300. For example, when it is detected that the light intensity is less than the first preset value, the DO terminal of the first detection component 210 outputs a high level. When it is detected that the light intensity is greater than or equal to the first preset value, the DO terminal of the first detection component 210 outputs a low level.

[0048] The second detection element 220 is used to detect the theoretical power and available power of the photovoltaic module. In some embodiments, in order to determine whether there is a power limit, the difference between the theoretical power and the available power can be calculated during the power limit, and this value is used as the threshold value P of the difference. 阀 That is the second preset value. Under normal circumstances, the difference between the theoretical power and the available power is less than P 阀 When power is limited, the difference between theoretical power and available power is greater than or equal to P 阀 .

[0049] The third detector 230 is used to detect the electrical quantity of the photovoltaic module, thereby determining whether the photovoltaic module is covered with snow. If the electrical quantity is less than or equal to a third preset value, the photovoltaic module is covered with snow, resulting in low power generation efficiency.

[0050] In some embodiments, the device is also equipped with a manual stop button. Before the air jet assembly 110 or the heating assembly 120 is activated, a command is sent to the main control computer. If a "yes" operation command is received or no command is received within one minute, both the air jet assembly 110 and the heating assembly 120 will start snow removal. If the weather conditions are too severe, the operator can also select the "no" button through the main control computer to disable snow removal by both the air jet assembly 110 and the heating assembly 120.

[0051] The theoretical power and available power of the photovoltaic module are measured. If the difference between the theoretical power and available power of the photovoltaic module is greater than a second preset value, power is limited, and neither the air injection assembly 110 nor the heating assembly 120 is activated, thereby reducing the risk of frequent starts and stops caused by false triggering of the device. If the difference between the theoretical power and available power of the photovoltaic module is less than or equal to the second preset value, power is not limited.

[0052] It is understandable that there is sufficient sunlight, the photovoltaic modules are covered with snow, the difference between the theoretical power and the available power of the photovoltaic modules is less than or equal to the second preset value, no power restriction occurs, and the snow removal device works.

[0053] That is, when power is not limited, if the light intensity is greater than or equal to a first preset value and the amount of electricity is less than or equal to a third preset value, the air jet assembly 110 and the heating assembly 120 are activated. The heating assembly 120 moves relative to the surface of the photovoltaic module to heat and melt the ice, while the air jet assembly 110 sprays air toward the surface of the photovoltaic module to remove snow without directly releasing the air from the surface of the photovoltaic module, thereby reducing scratches or marks on the surface of the photovoltaic module. This device thus reduces the frequent starting and stopping of the snow removal device and minimizes damage to the surface of the photovoltaic module, thereby extending the service life of the snow removal device and the surface of the photovoltaic module.

[0054] In some embodiments, the fixed component automatic snow removal tooling provided in the embodiments of the present application, the snow removal component 100 also includes a driving component 130 and a moving component 140, one end of the driving component 130 is connected to the jet component 110 to drive the jet component 110 to spray, and the other end is connected to the moving component 140 to drive the moving component 140 to move, the jet component 110 is set on the moving component 140, and the driving component 130 drives the jet component 110 to move relative to the surface of the photovoltaic component through the moving component 140.

[0055] In a specific implementation, the jet assembly 110 is arranged on the moving assembly 140. The moving assembly 140 is used to drive the jet assembly 110 to move relative to the surface of the photovoltaic assembly. The jet assembly 110 sprays air toward the surface of the photovoltaic assembly to remove snow.

[0056] In some embodiments, the photovoltaic module is arranged on a photovoltaic module support. The photovoltaic module support includes pillars, beams, support plates, and fixed plates; the pillars are connected obliquely to the beams and are vertically buried in the soil on the slope to support and fix the photovoltaic module; the beams are welded in a horizontal and vertical "well type" manner, and the support plates are laid parallel to the upper surface of the beams. The angle between the support plates and the pillars is the optimal inclination angle for the annual power generation of the photovoltaic module. The fixed plate is fixedly welded to the beam along the inclined surface of the photovoltaic module, and the fixed plate is the initial position of the mobile component 140. A track component 400 is provided on the photovoltaic module support, and the mobile component 140 moves along the track component 400.

[0057] One end of the drive assembly 130 is connected to the jet assembly 110, providing power for the jet assembly 110 to spray air toward the surface of the photovoltaic panel, thereby removing snow. The other end of the drive assembly 130 is connected to the moving assembly 140 to drive the moving assembly 140 to move. Thus, a single drive assembly 130 can both move the jet assembly 110 and spray air.

[0058] The snow removal device of the present embodiment utilizes a mobile assembly 140 to enable the air jet assembly 110 to move across the entire surface of the photovoltaic panel, thereby enhancing the range and effectiveness of snow removal. Furthermore, by controlling the speed of the mobile assembly 140, the speed can be reduced in areas with heavy snow accumulation, allowing the air jet assembly 110 to focus its jets on that area, further enhancing snow removal effectiveness.

[0059] In some other embodiments, the fixed component automatic snow removal tooling provided in the embodiments of the present application, the jet component 110 includes a jet body 111, a jet pipe 112 and a jet component 113, the jet body 111 has a jet chamber, the jet chamber has an inlet and an outlet, the jet component 113 is connected to the jet chamber inlet, the jet component 113 is connected to the drive component 130, the jet pipe 112 is connected to the outlet of the jet chamber, and the jet pipe 112 is used to spray toward the photovoltaic component.

[0060] In a specific implementation, the jet body 111 is a rectangular parallelepiped, and the jet range of the jet body 111 at least completely covers the width of the photovoltaic module. The jet body 111 has a jet chamber with an inlet and an outlet. The jet element 113 is connected to the outlet of the jet chamber. The jet element 113 is used to generate gas, and the jet pipe 112 is connected to the outlet of the jet chamber. The airflow is generated by the jet element 113, passes through the jet chamber, and flows out of the jet pipe 112, spraying toward the photovoltaic module to remove snow from the surface of the photovoltaic module.

[0061] The present application does not limit the specific structure of the jet component 113. For example, the jet component 113 may be a compressed air jet device or an airflow generator.

[0062] In some embodiments, the air jet pipes 112 are disposed on both sides of the air jet body 111 to facilitate snow removal from the surface of the photovoltaic module during reciprocating motion.

[0063] In the fixed-type automatic snow removal tool provided in the embodiment of the present application, the opening of the air jet pipe 112 is tilted toward the surface of the photovoltaic module.

[0064] In a specific implementation, the opening of the air jet 112 is tilted toward the surface of the photovoltaic module, so that the gas is ejected at a certain oblique angle, which is more consistent with the layout of the photovoltaic modules. For example, the opening of the air jet 112 is a beveled opening, ensuring that the air is discharged at an oblique direction, conforming to the surface of the photovoltaic module, increasing the air pressure and improving the snow removal effect. It should be noted that a certain gap is left between the air jet 112 and the surface of the photovoltaic module to avoid direct contact with the surface of the photovoltaic module and causing surface wear of the photovoltaic module.

[0065] The embodiment of the present application does not specifically limit the size and direction of the opening of the air injection pipe 112.

[0066] In some possible implementations, the fixed component automatic snow removal tool provided in the embodiment of the present application has a plurality of air jet pipes 112 , which are arranged at intervals on the air jet body 111 .

[0067] In a specific implementation, there are multiple air jet pipes 112 , which are spaced apart along the length direction of the air jet body 111 .

[0068] The present application does not specifically limit the arrangement of the jet pipes 112. For example, since snow easily accumulates in the middle of the surface of the photovoltaic module, the jet pipes 112 are distributed more densely in the middle of the jet body 111 to enhance the snow removal effect.

[0069] In some embodiments, the fixed component automatic snow removal tool provided in the embodiments of the present application, the jet component 113 includes a transmission gear set, a blower box 114 and a ventilation pipe 115, the blower box 114 has a blower chamber, and the blower chamber has an impeller 116, one end of the transmission gear set is socketed with the first output shaft of the drive component 130, and the other end is socketed with the impeller 116, and the blower chamber is connected to the jet chamber through the ventilation pipe 115.

[0070] In practice, the air-injection component 113 comprises a transmission gear set, a blower box 114, and a ventilation pipe 115. One end of the transmission gear set is sleeved with the first output shaft of the drive assembly 130, and the other end is sleeved with the impeller 116. A vent is provided on the blower box 114, which communicates with the air chamber. The vent is used to provide a source of air for the impeller 116 within the air chamber.

[0071] During jetting, the driving assembly 130 drives the impeller 116 to rotate through the transmission gear set, and the impeller 116 drives the gas to flow, enters the impeller 116 through the vent on the blower box, is pressurized by the impeller 116, and is discharged through the air ventilation pipe 115 to form a continuous airflow. The ventilation pipe 115 is connected to the jet body 111, passes through the jet cavity, and is jetted toward the photovoltaic module through the jet pipe 112.

[0072] In some embodiments, the air injection assembly 110 further includes a hinge 500 located below the ventilation tube 115. This hinge 500 shields the ventilation tube 115 during inhalation, preventing water or impurities from entering the tube and potentially affecting device operation. For example, if the motor is reversed and the air injection assembly 110 is in the inhalation state, hinge 500 shields the ventilation tube 115, preventing inhalation, while the heating assembly 120 continues to operate.

[0073] In some other possible implementations, the fixed component automatic snow removal tooling provided in the embodiment of the present application, the transmission gear set includes a blower tooth 117, a speed change tooth 118 and a transmission shaft 119, the blower tooth 117 is engaged with the speed change tooth 118, the speed change tooth 118 is sleeved on the transmission shaft 119, the impeller 116 is sleeved on the transmission shaft 119, and the blower tooth 117 is sleeved on the first output shaft of the drive component 130.

[0074] In a specific implementation, the blasting teeth 117 are mounted on the first output shaft of the drive assembly 130, and the blasting teeth 117 move synchronously with the first output shaft. The blasting teeth 117 mesh with the speed-changing teeth 118, which are mounted on the transmission shaft 119. The impeller 116 is sleeved on the transmission shaft 119. It should be noted that the blasting teeth 117 are large gears, and the speed-changing teeth 118 are small gears. The large gear drives the small gear, thereby increasing the speed of the impeller 116.

[0075] The embodiment of the present application does not impose any specific restrictions on the module and number of teeth of the blast teeth 117 and the speed change teeth 118, and they can be designed and selected according to specific circumstances.

[0076] In some optional implementations, the fixed component automatic snow removal tooling provided in the embodiment of the present application, the mobile component 140 includes a chassis 141, a roller shaft 142, a roller 143 and a transmission member 144, the roller 143 is sleeved on the roller shaft 142, the roller 143 is set at the bottom of the chassis, the jet component 110 is set on the chassis 141, one end of the transmission member 144 is sleeved with the roller shaft 142, and the other end is sleeved with the second output shaft of the drive component 130.

The power gear meshes with the first transmission helical gear, which are both sleeved on the first transmission shaft. The second transmission helical gear meshes with the driven gear, which is sleeved on the roller shaft 142. The power gear is sleeved on the second output shaft of the drive assembly 130. The drive assembly 130 rotates the first transmission helical gear via the power gear, which in turn rotates the second transmission helical gear via the first transmission shaft, thereby driving the driven gear to rotate, causing the roller shaft 142 to rotate. The rotation of the roller shaft 142 drives the roller 143 to rotate, thereby moving the jet assembly 110 relative to the surface of the photovoltaic assembly.

[0078] The jet assembly 110 is located above a chassis 141. A support member is provided at the bottom of the chassis 141. The support member is used to fix a roller shaft 142. A roller 143 is mounted on the roller shaft 142. The roller 143 rotates around the roller shaft 142. For example, a track assembly 400 is provided around the photovoltaic module.

[0080] In some embodiments, the number of support members is 6, the number of rollers 143 is 6, and the number of roller shafts 142 is 2.

The travel switch is positioned in correspondence with the roller shaft 142. The travel switch activates internal contacts through the collision or displacement of its components, connecting or disconnecting the circuit. When the mobile assembly 140 reaches a preset position, the travel switch triggers a corresponding control action, causing the mobile assembly 140 to reverse direction and return to its initial position, thus achieving reciprocating motion of the snow removal assembly 100.

The beams are welded horizontally and vertically in a "well" pattern, with the support plates laid parallel to the top surfaces of the beams. The angle between the support plates and the pillars represents the optimal inclination angle for the photovoltaic module's annual power generation. The fixed plates are welded to the beams along the slope of the photovoltaic module and represent the initial position of the mobile module 140.

[0084] In some embodiments, the track assembly 400 includes three moving tracks, which are correspondingly arranged on both sides and the center line of the support plate along its length. The photovoltaic module is located between the moving tracks.
