Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fire protection system technology, specifically relating to a fire protection structure for a solar photovoltaic power generation system. Background Technology
[0002] As a new energy source, solar energy has advantages over conventional energy sources, such as abundant resources, cleanliness and no pollution, convenient development and utilization, and no need for transportation. Photovoltaic power generation is based on the photovoltaic effect principle, which directly converts sunlight into electrical energy through solar cells. A photovoltaic power generation system mainly consists of three core parts: solar panels, controllers, and inverters. These are mainly composed of electronic components. Currently, photovoltaic power generation is gradually entering the daily household field, and its application scope is constantly expanding.
[0003] Chinese patent CN219087068U discloses a solar photovoltaic power generation device. By setting a protective structure on the top of the solar panel, when the solar panel is not in use, a servo motor can be activated to drive a rainproof cloth to move up and down and back and forth to protect the surface of the solar panel. This prevents dust and water from falling onto the top of the solar panel and causing damage, effectively improving the protective performance of the solar photovoltaic power generation device.
[0004] As the duration of sunlight exposure increases, the surface temperature of solar panels rises. This can not only damage internal components and increase the risk of fire, but also reduce power generation efficiency. Prolonged exposure to direct sunlight leads to heat accumulation, which, if not effectively dissipated, will threaten critical components such as battery modules, accelerate the aging process, and increase the risk of failure. At the same time, high temperatures will reduce the conversion efficiency of solar cells and reduce effective energy output. Utility Model Content

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0027] Embodiment one:
[0028] Please refer to Figures 1 to 4 As shown in the figure, a fire-fighting structure for solar photovoltaic power generation system, comprising:
[0029] Photovoltaic power generation panel 1;
[0030] A support frame 2 is installed on both sides of the bottom end of the photovoltaic panel 1. A counterweight base 3 is installed at the bottom end of each of the two support frames 2. A positioning seat 4 is installed between the opposite surfaces of the two counterweight bases 3.
[0031] Limiting baffles 5 are installed on both sides of the top of the positioning seat 4. A removal mechanism 6 is installed in the middle of the opposite face of the two limiting baffles 5. Three pressing mechanisms 7 are installed in the middle of the top of the positioning seat 4. Several positioning slots 8 are opened on the top of the positioning seat 4. A carbon dioxide fire extinguisher 9 is placed inside the several positioning slots 8.
[0032] Depend on Figures 1 to 3 It can be seen that a fixing frame 10 is installed between the upper part of the opposite surfaces of the two limiting baffles 5, and three fixing plates 11 are installed between the inner walls of the two sides of the fixing frame 10. Two cooling nozzles 12 are installed on both sides of the top of the three fixing plates 11, and transmission pipes 13 are installed at the bottom of the multiple cooling nozzles 12. Temperature sensors 14 are installed in the middle of the bottom of the three fixing plates 11, and the tops of the three temperature sensors 14 are installed at the bottom of the photovoltaic power generation panel 1.
[0033] The removal mechanism 6 includes a removal frame 61, an electric push rod 62, a removal rod 63, a threaded groove 64, and a limiting nut 65. The electric push rod 62 is installed at one end of the removal frame 61, and the other end of the electric push rod 62 is installed on the inner wall of the limiting baffle 5 on one side. The removal rod 63 is inserted and movably installed between the inner walls of both sides of the removal frame 61. There are two threaded grooves 64 and two limiting nuts 65. The two threaded grooves 64 are respectively opened on both sides of the outer surface of the removal rod 63, and the two limiting nuts 65 are respectively installed on the removal rod 63 through the corresponding threaded grooves 64.
[0034] From the above, first, the photovoltaic power generation panel 1 is inclined and supported by the support frame 2, so that the photovoltaic power generation panel 1 can fully absorb solar energy and convert solar energy into electrical energy, realizing the function of photovoltaic power generation, and at the same time, the temperature sensor 14 can sense the temperature of the photovoltaic power generation panel 1 in real time, and when the temperature exceeds the set value, the pull-out mechanism 6 and the pressing mechanism 7 will be started in turn, the electric push rod 62 in the pull-out mechanism 6 will retract and move, thereby changing the position of the pull-out frame 61, so that the pull-out rod 63 moves and pulls out the safety pin on the carbon dioxide fire extinguisher 9, then the pressing mechanism 7 triggers multiple carbon dioxide fire extinguishers 9, so that the carbon dioxide gas is transported to the cooling nozzle 12 through the transmission pipe 13 and sprayed out, so that the gas uniformly covers the back of the photovoltaic power generation panel 1 for cooling treatment. This process can effectively reduce the working temperature of the photovoltaic power generation panel 1, prevent high temperature from damaging the internal devices of the photovoltaic power generation panel 1, thereby reducing the fire hazard and improving safety, and at the same time, it can also avoid the photovoltaic power generation panel 1 due to high temperature. Reducing the solar energy conversion efficiency, thereby reducing energy loss and improving the power generation efficiency of the photovoltaic power generation panel 1, when the carbon dioxide fire extinguisher 9 needs to be replaced, the limiting nut 65 can be rotated to remove it from the pull-out rod 63, and the removed safety pin is separated from the pull-out rod 63, then the pull-out rod 63 passes through the safety pin and the pull-out frame 61 of the new carbon dioxide fire extinguisher 9 in turn, and the limiting nut 65 is sleeved on the pull-out rod 63 to realize limiting.
[0035] Specifically, referring to Figures 1 to 3 As shown in the figure, the electric push rod 62 is electrically connected with the temperature sensor 14, the inner diameter of the pull-out rod 63 is consistent with the inner diameter of the safety pin on the carbon dioxide fire extinguisher 9, and the support frame 2 is provided in a triangular structure.
[0036] As can be seen from the above, when the temperature sensor 14 detects abnormal temperature, the electric push rod 62 can be controlled to start or stop, so that the pull-out rod 63 can be accurately inserted and pulled out, and the carbon dioxide fire extinguisher 9 is ready for use, and the triangular structure of the support frame 2 has stability and strength, providing stable support for the photovoltaic power generation panel 1.
[0037] Example two:
[0038] Referring to Figure 4 As shown in the figure, the pressing mechanism 7 includes an electric telescopic rod 71, a fixed bolt 72, a fixed nut 73, and a pressing frame 74, the electric telescopic rod 71 is installed at the top end of the positioning seat 4, the fixed bolt 72 is installed at the top end of the electric telescopic rod 71, the fixed nut 73 is installed on the outer surface of the fixed bolt 72 upper part, and the pressing frame 74 is installed on the outer surface of the fixed bolt 72 lower part.
[0039] As can be seen from the above, when the temperature sensor 14 monitors that the temperature of the photovoltaic panel 1 is too high, it will control the start of the electric telescopic rod 71, through the fixing effect of the fixed nut 73 on the pressing frame 74, the fixed bolt 72 will pull down the pressing frame 74, so that the pressing frame 74 can press the corresponding two carbon dioxide fire extinguishers 9 at the same time, and the carbon dioxide gas in the two carbon dioxide fire extinguishers 9 is released, and then the photovoltaic panel 1 is cooled down. In addition, when the carbon dioxide fire extinguisher 9 needs to be replaced, the fixed nut 73 is loosened to cancel the fixation of the pressing frame 74. At this time, the pressing frame 74 can be rotated to adjust its position, or it can be completely removed to avoid blocking the carbon dioxide fire extinguisher 9, so that the carbon dioxide fire extinguisher 9 can be taken out of the positioning groove 8 and replaced.
[0040] Preferably, as shown in the figure, the electric telescopic rod 71 is electrically connected with the temperature sensor 14, and the pressing frame 74 is arranged in an I-shaped structure, and the pressing frame 74 is located directly above the two carbon dioxide fire extinguishers 9. Figure 4
[0041] As can be seen from the above, the start or stop of the electric telescopic rod 71 can be controlled by the temperature sensor 14, which is used to realize the action of pressing the fire extinguisher. The I-shaped structure usually has good strength and stability, which ensures that the pressing frame 74 can accurately press the pressure handle of the carbon dioxide fire extinguisher 9 and deliver enough pressure to start the fire extinguisher. This means that when the pressing frame 74 is pulled by the electric telescopic rod 71, it can press the pressure handle of the two carbon dioxide fire extinguishers 9 at the same time, achieving the effect of starting two fire extinguishers at the same time.
[0042] Application example:
[0043] The design is mainly applied to outdoor photovoltaic power stations, especially in sparsely populated, densely vegetated areas or large unattended photovoltaic power station environments. In these environments, photovoltaic panels are usually laid out in large areas to form photovoltaic arrays, and are connected to the power grid through inverters, booster stations and other equipment. Because the photovoltaic panels are exposed to the outdoors for a long time, they are affected by direct sunlight and temperature changes, and their temperature may rise sharply. The fire-fighting structure can monitor the temperature of the photovoltaic panel 1 in real time through the temperature sensor 14. When the monitored temperature exceeds the set value, the temperature sensor 14 will trigger the start of the pulling mechanism 6 and the pressing mechanism 7 in turn. The pulling mechanism 6 will pull out the safety pin of the carbon dioxide fire extinguisher 9, and then the pressing mechanism 7 will press the pressure handle of the carbon dioxide fire extinguisher 9, so that the carbon dioxide in the carbon dioxide fire extinguisher 9 is sprayed towards the photovoltaic panel 1, thereby reducing the temperature of the photovoltaic panel 1 and effectively preventing the occurrence of burning and the occurrence of fire. This not only greatly improves the safety of the photovoltaic power station, but also significantly reduces the damage to the equipment and the loss of electricity caused by fire.
