Abstract

Technical Field
[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to an automatic snow removal photovoltaic support system suitable for high-altitude and cold regions. Background Technology
[0002] The statements in this section are provided only as background information in connection with this disclosure and may not constitute prior art.
[0003] High-altitude, frigid regions experience low temperatures and long periods of freezing, placing higher demands on the anti-freezing capabilities of photovoltaic modules and mounting structures. Furthermore, these areas typically have thick snow cover and long snow-covered periods in winter, severely shading photovoltaic modules and causing significant losses in power generation from photovoltaic power plants.
[0004] Currently, snow is usually cleared from components using manual labor or mechanical equipment such as drones. Both methods are generally inefficient and require a lot of manpower and resources.
[0005] Chinese patent (CN218243464U) discloses a snow removal photovoltaic bracket and photovoltaic equipment. It uses a phase change material heat storage part to store heat energy. When snow removal is needed, the stored heat energy is transported to the photothermal component for snow removal. This structure requires phase change heat storage material and heat energy conversion system, which has relatively high cost and short life.
[0006] Chinese patent (CN218243464U) discloses a snow removal photovoltaic bracket and photovoltaic equipment. The snow is melted and cleaned by an electric heating tube inside the heating frame and a fan. The device also uses a motor, and its cost and lifespan are difficult to guarantee.
[0007] Due to the aforementioned technical problems in cleaning snow off photovoltaic system modules in high-altitude and cold regions, there is an urgent need for a support system that can efficiently and economically clean snow off the modules automatically. Utility Model Content

[0011] Furthermore, the photovoltaic module fixing component is composed of several parallel photovoltaic module fixing inclined beams.
[0012] Furthermore, the top of the photovoltaic module fixing beam is hinged to the reset device, and the lower part of the middle of the photovoltaic module fixing beam is hinged to the top of the low column.

[0014] Furthermore, one end of the damping recovery telescopic rod is hinged to the top of the photovoltaic module fixing inclined beam, and the other end is hinged to the top of the high-level column.
[0015] Furthermore, a support rod is provided between the low-position column and the high-position column.
[0016] Furthermore, the damped reversible telescopic rod can be configured with a sliding threshold.
[0017] Compared with existing technologies, the beneficial effects of this utility model are:

[0023] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0024] Example 1
[0025] Please see Figure 1-2 An automatic snow removal photovoltaic support system suitable for high-altitude and cold regions includes: a photovoltaic module fixing component, a low-level column 4, a high-level column 5, and a reset device; the height of the low-level column 4 is lower than the height of the high-level column 5; one end of the photovoltaic module fixing component is hinged to one end of the reset device, and the other end of the reset device is hinged to the top of the high-level column 5; the middle part of the photovoltaic module fixing component is hinged to the top of the low-level column 4; the reset device provides a reset force to the photovoltaic module fixing component towards the high-level column 5; that is, it can automatically remove snow from the top of the photovoltaic module 1 while achieving tilt support, avoiding the significant loss of power generation of the photovoltaic power station caused by long-term snow accumulation in high-latitude and cold regions.
[0026] In this embodiment, specifically, the photovoltaic module fixing component is composed of several parallel photovoltaic module fixing inclined beams 3.
[0027] In this embodiment, specifically, the top of the photovoltaic module fixing beam 3 is hinged to the reset device, and the lower part of the middle of the photovoltaic module fixing beam 3 is hinged to the top of the low column 4.
[0028] In this embodiment, specifically, the reset device is a damped return telescopic rod 6.
[0029] In this embodiment, specifically, one end of the damping recovery telescopic rod 6 is hinged to the top of the photovoltaic module fixing inclined beam 3, and the other end is hinged to the top of the high-position column 5.
[0030] In this embodiment, specifically, a support rod 7 is provided between the low-position column 4 and the high-position column 5 to increase the overall rigidity of the support system.
[0031] In this embodiment, specifically, the damping restoring telescopic rod 6 can be set with a sliding threshold to ensure that the support system's tilt angle remains unchanged under positive and negative wind conditions; when a certain snow thickness is reached, causing the additional bending moment generated by the weight of the snow to exceed the restoring torque of the damping rod, the damping rod elongates, the tilt angle of the support and components increases, and the snow slides off; as the snow slides off, the tilt angle of the support decreases due to the restoring torque of the damping rod, restoring it to normal operating condition.
[0032] Under normal operating conditions, such as Figure 1 As shown, the photovoltaic module fixing beam 3 is supported on the top of the damping recovery telescopic rod 6 and the top of the low column 4. Since the span of the top of the damping recovery telescopic rod 6 and the top of the low column 4 is greater than half the width of the photovoltaic module 1, the photovoltaic module 1 fixed on the photovoltaic module fixing beam 3 remains stable under the action of gravity and forms a certain angle α with the horizontal plane.
[0033] When there is snow covering photovoltaic module 1, the snow will slide down the inclined surface due to its own weight and accumulate under the obstruction of the lower frame of photovoltaic module 1. At this time, as Figure 2 As shown, since the downward bending moment generated by the gravity of the snow is greater than the bending moment generated by the restoring force of the damping restoring telescopic rod 6, the photovoltaic module 1 will slowly rotate around the hinge point of the low-position column 4 under the damping action of the damping restoring telescopic rod 6, thereby increasing the tilt angle of the photovoltaic module 1. At this time, the tilt angle β is greater than α, which can dump the snow onto the ground, thereby avoiding the loss of power generation caused by long-term shading by snow. After the snow is dumped, the photovoltaic module 1 returns to its original position under the action of the damping restoring telescopic rod 6.
[0034] This utility model is applicable to an automatic snow removal photovoltaic support system in high-altitude and cold regions. It uses a mechanical device to automatically slide off the accumulated snow, avoiding the loss of power generation caused by long-term snow cover in high-latitude regions. It also avoids the need for maintenance personnel to manually shovel snow in conventional ground-mounted photovoltaic power stations, making operation and maintenance more convenient. At the same time, the device is a mechanical structure that does not require any electricity or power drive, resulting in higher reliability and lower investment, which is more conducive to improving the profitability of the power station.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
