DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than 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 protection scope of the utility model.

[0027] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0028] Embodiment one: a safety fence for a photovoltaic power station, comprising a bottom plate 1 and a fixed plate 101, the fixed plate 101 is fixedly installed on the upper surface of the bottom plate 1, and the upper surface of the bottom plate 1 is provided with a fence device;

[0029] The fence device comprises a fixed unit and a moving unit. The fixed unit comprises a fixed column 3, a groove 301, a threaded column 302 and a driving motor 303. The fixed column 3 is fixedly installed on the upper surface of the bottom plate 1. The groove 301 is opened on the side surface of the fixed column 3. The threaded column 302 is installed on the inner bottom surface of the groove 301. The driving motor 303 is fixedly installed on the upper surface of the fixed column 3. The inner top surface of the groove 301 penetrates a hole. One end of the threaded column 302 penetrates the hole and is fixedly connected with the output end of the driving motor 303. The fixed columns 3 are symmetrically distributed on both sides of the upper surface of the bottom plate 1. The side surface of one end of the fixed column 3 is fixedly connected with the side surface of the fixed plate 101.

[0030] The moving unit comprises a moving block 304, a square plate 305 and a light-transmitting groove 306. The moving block 304 is fixedly installed on the outer surface of the threaded column 302. The square plate 305 is fixedly installed on the side surface of the moving block 304. The light-transmitting groove 306 penetrates the front surface of the square plate 305. The upper surface of the moving block 304 penetrates a hole, and the inner wall of the hole is provided with a thread. The outer surface of the threaded column 302 is engaged with the thread. The moving block 304 is distributed on the upper and lower sides of the outer surface of the threaded column 302. By setting the fixed unit, the fixed column 3 is fixedly supported. By driving the threaded column 302 to rotate through the driving motor 303, the square plate 305 is driven to move to adjust the height of the protection to improve the safety of the fence and effectively protect the photovoltaic power station.

[0031] The height of the square plate 305 is at least 2 meters. The material of the square plate 305 is alloy steel, which has sufficient strength to withstand certain external impact. Considering that the roof distributed photovoltaic power station may be subjected to wind, sunlight and other natural factors and occasional accidental collision, the material of the safety fence can be selected from strong materials such as galvanized steel pipe. In the coastal area of the distributed photovoltaic power station, due to the influence of strong wind such as typhoon, the wind resistance of the safety fence should be higher, and the wall thickness of the steel pipe can be appropriately increased.

[0032] Various safety warning signs can be integrated on the square plate 305 of the safety fence. For example, "high voltage danger", "prohibit climbing", "photovoltaic power generation area, non-working personnel are prohibited to enter" and other signboards. These signboards can adopt eye-catching colors such as red and yellow to ensure that they can be clearly visible under different lighting conditions.

[0033] The infrared induction sensor and the vibration sensor are installed on the square plate 305. When a person touches or climbs the guardrail, the sensor sends a signal to the monitoring system of the photovoltaic power station, and the monitoring system of the photovoltaic power station can timely issue an alarm and record relevant information. In this way, real-time monitoring of the safety of the power station can be realized, and the safety of the power station can be improved.

[0034] The color of the square plate 305 should be coordinated with the overall appearance of the photovoltaic power station. If the photovoltaic components, supports and other main equipment of the photovoltaic power station adopt silver gray tone, the square plate 305 can select a color close to it, such as dark gray or black, so that the entire power station looks more neat and unified.

[0035] The driving motor 303 works to drive the threaded column 302 to rotate, and through the threaded engagement, the moving block 304 drives the square plate 305 to move up and down on the outer surface of the threaded column 302 to adjust the height of the square plate 305, thereby facilitating the protection of the photovoltaic power station.

The inner wall of the shaft hole 316 penetrating the upper surface of the connecting sleeve 315 is connected with the outer surface of the rotating shaft 312. By arranging the connecting mechanism, the two guardrails can be connected and fixed through the rotating shaft 312 and the connecting sleeve 315, and then can be rotated to surround and protect the photovoltaic power station. At the same time, the lowering of the lifting column 309 drives the supporting base 310 to support the entire guardrail to maintain good stability.

[0037] The side of the bottom plate 1 is provided with a supporting mechanism, which includes a bearing plate 307, an air cylinder 308, a lifting column 309 and a supporting base 310. The bearing plate 307 is fixedly installed on the side of the bottom plate 1. The air cylinder 308 is fixedly installed on the upper surface of the bearing plate 307. The lifting column 309 is installed on the output end of the air cylinder 308. The supporting base 310 is fixedly installed on the bottom surface of the lifting column 309.

[0038] Two guardrails are fixed between the connecting sleeves 315 and the sleeves between the rotating shafts 312, and can be rotated to adjust the position of the guardrails after being fixed. After adjustment, the cylinder 308 drives the lifting column 309 to lower the supporting base 310 to support and fix the entire guardrail.
