Description

Technical Field

[0001] This utility model relates to the field of photovoltaic transformer substation technology, and in particular to a cable safety support platform for photovoltaic transformer substations. Background Technology

[0002] A photovoltaic transformer substation is a combination of a photovoltaic power conversion box and a transformer substation foundation. It is mainly used for power conversion in photovoltaic power plants and rooftop solar facilities. It is a pre-wired equipment package designed to meet the growing demand for large-scale solar power plants and rooftop solar facilities.

[0003] Currently, the specific functions of photovoltaic transformer substations include converting direct current (DC) generated by solar panels into alternating current (AC), and regulating the voltage through a transformer to meet the needs of different loads. During the conversion process, power needs to be transmitted through cables. Existing cables from photovoltaic transformer substations are directly exposed to the outdoor environment, making them susceptible to swaying and shaking due to strong winds. The swaying cables may collide and rub against other objects, causing damage to the cable sheath, reducing their lifespan, and also posing serious safety hazards to power supply.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] Please see Figures 1-4This utility model provides a cable safety support platform for a photovoltaic transformer substation, including a base plate 1. Four fixed columns 2 are fixedly connected to the bottom surface of the base plate 1. A fixed plate 8 is fixedly connected to the outer surface of each fixed column 2. A support plate 3 is fixedly connected to the four fixed plates 8. A protective shell 7 and a limiting plate 12 are fixedly connected to the upper surface of the support plate 3 by screws. The limiting plate 12 has a horizontal limiting groove communicating with the inner cavity of the protective shell 7. A baffle 14 is movably hinged to one side of the protective shell 7. A pull handle 15 is fixedly connected to the outer side of the baffle 14. The cable 5 is coiled inside the protective shell 7, and its inner end passes through the protective shell 7 and the base plate 1 in sequence to connect with the main body 4 of the photovoltaic transformer substation. The main body 4 of the photovoltaic transformer substation is set on the upper surface of the base plate 1. The outer end of the cable 5 passes horizontally through the limiting groove of the limiting plate 12, and its outer surface is in contact with the inner wall of the limiting groove.

[0021] The support plate 3 and the protective shell 7 can fix and limit the cable 5 coming out of the photovoltaic transformer body 4, effectively preventing it from swaying and shaking due to external environmental interference, which would cause damage to its surface.

[0022] In this embodiment, a reinforcing ring 6 is fixedly connected to the top of each fixed column 2. The top surface of the reinforcing ring 6 is welded to the bottom surface of the base plate 1. The reinforcing ring 6 can reinforce the fixed column 2 and the base plate 1, thereby enhancing the stability of the device.

[0023] In this embodiment, each fixing plate 8 is fixedly connected to a reinforcing plate 9. The reinforcing plate 9 has a groove adapted to the thickness of the supporting plate 3, and an adjusting screw 10 is provided on the groove. The supporting plate 3 has oblong holes at its four corners. The supporting plate 3 is clamped in the groove of the reinforcing plate 9 and fixed by the adjusting screw 10 passing through its oblong holes. The position of the supporting plate 3 can be adjusted by the adjusting screw 10, which facilitates the connection of the cable 5 to the photovoltaic transformer body 4 during installation.

[0024] In this embodiment, two reinforcing frames 16 are welded to both ends of the pull handle 15. Each reinforcing frame 16 is welded to the side of the baffle 14. The reinforcing frames 16 can reinforce the pull handle 15 and the baffle 14, thereby improving reliability.

[0025] In this embodiment, four limiting blocks 11 are welded to the upper surface of the support plate 3. Each limiting block 11 has a limiting groove, and the four corners of the protective shell 7 are engaged in the limiting grooves of the four limiting blocks 11. The limiting blocks 11 can restrict the position of the protective shell 7, thereby further fixing and limiting it, and preventing it from being affected by external environmental interference during use, which could cause the screws to loosen and the position of the protective shell 7 to shift.

[0026] In this embodiment, a limiting frame 13 is fixedly connected to the upper surface of the support plate 3. The inner wall of the limiting frame 13 is in contact with the outer surface of the limiting plate 12. The limiting frame 13 can restrict the position of the limiting plate 12 and prevent the limiting plate 12 from shifting due to loose screws.

[0027] Working principle: In use, first place the cable 5 in the protective shell 7 on the support plate 3. Then, pass one end of the cable 5 through the protective shell 7 and place it in the limiting plate 12. Next, pass the other end of the cable 5 through the protective shell 7 and the base plate 1 in sequence, and connect it to the photovoltaic transformer main body 4. The limiting plate 12 further restricts the position of the cable 5, playing a fixed and limiting role, and enhancing the stability of the device. When maintenance and inspection of the cable 5 are required, simply pull the handle 15 to open the baffle 14, which facilitates maintenance and inspection of the cable 5 inside the protective shell 7, enhancing the effectiveness of the device.
