Some photovoltaic stations are located in mountainous areas, where rain and snow are more frequent, and photovoltaic modules are prone to snow accumulation, which affects their photoelectric conversion efficiency and leads to a decrease in power generation.

[0036] Photovoltaic stations are photovoltaic power generation systems that use photovoltaic modules to convert solar energy into electrical energy and transmit the electrical energy to the power grid by connecting to the power grid. Some photovoltaic stations are located in mountainous areas, where rain and snow are more frequent, and photovoltaic modules are prone to snow accumulation, which affects their photoelectric conversion efficiency and leads to a decrease in power generation.

[0037] In order to solve the problem of snow accumulation on photovoltaic modules, existing automatic snow removal devices are equipped with large-area snow pushing devices, such as rolling bristles. The device is also equipped with a sensor for receiving light signals and converting the light signals into electrical signals. When the electrical signal changes, the device recognizes snow accumulation and triggers the snow removal action, that is, driving the snow pushing device, such as rolling bristles, to move relative to the surface of the photovoltaic module, thereby removing snow.

[0038] However, the above-mentioned device is in direct contact with the surface of the photovoltaic module, which may easily cause scratches or crushing to the photovoltaic module. In the case of power shortage, it may easily cause changes in electrical signals. Even in the absence of snow accumulation, 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, the embodiment of the present application provides a fixed component automatic snow removal tool, including: 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 is connected to the heating component, and the air jet component is 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.

When the difference between the theoretical power and the available power is greater than the second preset value, that is, power limit, the air jet component and the heating component are not started, reducing the frequent start and stop caused by false triggering of the device. When the difference between the theoretical power and the available power is less than or equal to the second preset value, that is, there is no power restriction, at this time, if the light intensity is greater than or equal to the first preset value, and the electrical quantity is less than or equal to the third preset value, the jet assembly and the heating assembly are controlled to start, the heating assembly moves relative to the surface of the photovoltaic assembly to heat and melt the ice layer, and the jet assembly sprays toward the surface of the photovoltaic assembly to remove snow, and does not directly release from the surface of the photovoltaic assembly, thereby reducing scratches or scratches on the surface of the photovoltaic assembly. Therefore, the device not only reduces the frequent start and stop of the snow removal assembly, but also reduces the damage to the surface of the photovoltaic assembly.

[0040] Combination 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, including: 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, the air jet component 110 is arranged toward the photovoltaic component, the air jet component 110 is used to move relative to the surface of the photovoltaic component to remove snow from the surface of the photovoltaic component, and the heating component 120 moves relative to the surface of the photovoltaic component to heat the surface of the photovoltaic component;

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

[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 jet assembly 110 is disposed toward the surface of the photovoltaic assembly and is used to spray air toward the surface of the photovoltaic assembly. The heating assembly 120 is used to heat the surface of the photovoltaic assembly to melt snow on the surface. The embodiment of the present application does not limit the specific structure of the heating assembly 120. For example, the heating element of the heating assembly 120 is a high-temperature electric heating wire.

[0046] The jet assembly 110 moves relative to the surface of the photovoltaic assembly to remove snow from the surface of the photovoltaic assembly. 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 assembly, or the movement assembly 140 and the track assembly 400 can be used to achieve the movement of the jet assembly 110 relative to the surface of the photovoltaic assembly, which is not limited in the embodiments 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 receiving effect. Therefore, the first detection component 210 is a photosensitive sensor with waterproof performance and high transmittance. This sensor is IP67 grade, can cope with humid environments, and ensures 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, and 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 during the power limit can be calculated, 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 detection element 230 is used to detect the electrical quantity of the photovoltaic module, and to determine whether the photovoltaic module is covered with snow by detecting the electrical quantity of the photovoltaic module. When the electrical quantity is less than or equal to the third preset value, the photovoltaic module is covered with snow, resulting in low power generation efficiency.

[0050] In some embodiments, the device is also provided with a manual stop button. Before the jet assembly 110 or the heating assembly 120 is started, a command will be sent to the main control computer. When a "yes" operation command is received or there is no command within 1 minute, the jet assembly 110 and the heating assembly 120 both start the snow removal operation. If due to real-time weather factors, the operator can also select the "no" button through the main control computer, and the jet assembly 110 and the heating assembly 120 will not start the snow removal operation.

[0051] By measuring the theoretical power and available power of the photovoltaic module, when the difference between the theoretical power and available power of the photovoltaic module is greater than the second preset value, power is limited, and the jet assembly 110 and the heating assembly 120 are not started, so as to reduce frequent start and stop caused by false triggering of the device. When 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 components are covered with snow, the difference between the theoretical power and the available power of the photovoltaic components is less than or equal to the second preset value, no power restriction occurs, and the snow removal device works.

[0053] That is, there is no power restriction. At this time, if the light intensity is greater than or equal to the first preset value, and the amount of electricity is less than or equal to the third preset value, the jet assembly 110 and the heating assembly 120 are controlled to start, the heating assembly 120 moves relative to the surface of the photovoltaic assembly to heat and melt the ice layer, and the jet assembly 110 sprays toward the surface of the photovoltaic assembly to remove snow, and does not directly release from the surface of the photovoltaic assembly, thereby reducing scratches or scratches on the surface of the photovoltaic assembly. As a result, the device not only reduces the frequent start and stop of the snow removal device, but also reduces the damage to the surface of the photovoltaic assembly, thereby extending the service life of the snow removal device and the surface of the photovoltaic assembly.

[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 disposed 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 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 obliquely connected to the beams and are vertically buried in the soil on the slope to support and fix the photovoltaic module; the beams are horizontally and vertically welded in a "well type", and the support plates are laid parallel to the upper surface of the beams, and the angle between the support plates and the pillars is the optimal inclination angle for 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 moving component 140. A track component 400 is provided on the photovoltaic module support, and the moving component 140 moves along the track component 400,

[0057] One end of the driving assembly 130 is connected to the jet assembly 110 to provide jet power for the jet assembly 110 to drive the jet assembly 110 to spray toward the surface of the photovoltaic assembly to remove snow. The other end of the driving assembly 130 is connected to the moving assembly 140 to drive the moving assembly 140 to move. Thus, one driving assembly 130 can realize the movement and jet of the jet assembly 110.

[0058] The snow removal device in the embodiment of the present application can move the jet assembly 110 to cover the entire surface of the photovoltaic assembly through the moving assembly 140, thereby improving the scope and effect of snow removal. Moreover, by controlling the speed of the moving assembly 140, the moving speed can be reduced for areas with thick snow, so that the jet assembly 110 can concentrate the jet on the area, thereby improving the snow removal effect.

[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 range along the width direction of the photovoltaic module. The jet body 111 has a jet cavity, and the jet cavity has an inlet and an outlet. The jet member 113 is connected to the outlet of the jet cavity. The jet member 113 is used to generate gas, and the jet pipe 112 is connected to the outlet of the jet cavity. The airflow is generated from the jet member 113, passes through the jet cavity, and flows out from the jet pipe 112, and is sprayed 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 inclined toward the surface of the photovoltaic module.

[0064] In a specific implementation, the opening of the jet pipe 112 is tilted toward the surface of the photovoltaic module, and the gas is sprayed at a certain oblique angle, which is more in line with the layout of the photovoltaic module. For example, the opening of the jet pipe 112 is an oblique opening to ensure that the air is discharged in an oblique direction, fits the surface of the photovoltaic module, increases the jet pressure, and improves the snow removal effect. It should be noted that there is a certain gap between the jet pipe 112 and the surface of the photovoltaic module to avoid direct contact with the surface of the photovoltaic module, which causes 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 arranged at intervals 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 densely distributed in the middle of the jet body 111 to enhance the snow removal effect.

[0069] In some embodiments, the fixed component automatic snow removal tooling 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 blow chamber, and the blow chamber has an impeller 116, one end of the transmission gear set is sleeved with the first output shaft of the drive component 130, and the other end is sleeved with the impeller 116, and the blow chamber is connected to the jet chamber through the ventilation pipe 115.

[0070] In specific implementation, the jet component 113 includes 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 driving assembly 130, and the other end is sleeved with the impeller 116. The blower box 114 is provided with a vent, which is connected to the blast chamber. The vent is used to provide a gas source for the impeller 116 in the blast 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, enter the impeller 116 through the vent on the blower box, be pressurized by the impeller 116, and be discharged through the air ventilation pipe 115 to form a continuous airflow. The ventilation pipe 115 is connected to the jet body 111, and the jet is sprayed toward the photovoltaic component through the jet chamber and the jet pipe 112.

[0072] In some embodiments, the jet assembly 110 further includes a hinge 500, which is located at the lower side of the ventilation pipe 115 and shields the ventilation pipe 115 during inhalation to prevent water or impurities from entering the ventilation pipe 115 and affecting the operation of the device. For example, when the motor is reversed, the jet assembly 110 is in the inhalation state, but the hinge 500 shields the ventilation pipe 115 and does not perform the inhalation operation, and 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 gear 118 and a transmission shaft 119, the blower tooth 117 is meshed with the speed gear 118, the speed gear 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 assembly 130.
