Detailed Implementation
[0023] The following is combined with Figure 1-3 This utility model will be described in detail.
[0024] A medium-voltage device for photovoltaic mounting includes a medium-voltage base 10 and a fixed base 20. The medium-voltage base 10 is provided with a pressing edge 101 for pressing the photovoltaic panel. The fixed base 20 is located below the medium-voltage base 10 and is slidably fitted to the medium-voltage base 10. A reset member 30 is provided between the medium-voltage base 10 and the fixed base 20. The device also includes a locking member 40, which passes through the medium-voltage base 10 and the fixed base 20 along the height direction of the medium-voltage base 10 and the fixed base 20. The head end of the locking member 40 is engaged with the upper end surface of the medium-voltage base 10, and the end of the locking member 40 is threadedly fitted with a locking block 50 located below the medium-voltage base 10 and the fixed base 20. By rotating the locking member 40, the position of the medium-voltage base 10 relative to the fixed base 20 can be adjusted lower or higher. The distance between the upper surface of the intermediate pressure seat 10 and the lower surface of the fixed seat 20 can be adjusted by the locking component 40, thereby adjusting the height of the pressing edge 101. This adapts to different photovoltaic panel thicknesses, eliminates the need for on-site secondary processing, facilitates installation, and offers strong flexibility and adaptability, improving photovoltaic panel installation efficiency. Specifically, the locking component 40 is an M8 bolt; the locking block 50 has a threaded hole 501 along its own height direction for engaging with the threaded end of the locking component 40.
[0025] In this embodiment, the bottom of the medium pressure seat 10 is provided with a U-shaped groove 102, and the fixing seat 20 is a U-shaped fixing seat 20. The inner walls on both sides of the U-shaped groove 102 are slidably fitted to the outer walls on both sides of the U-shaped fixing seat 20.
[0026] In this embodiment, an anti-slip portion is provided between the intermediate pressure seat 10 and the fixed seat 20; further, the anti-slip portion is a corrugated surface 60 provided on the side wall of the intermediate pressure seat 10 and / or the fixed seat 20. The corrugated surface 60 enhances the friction between the intermediate pressure seat 10 and the fixed seat 20, and can also prevent the pressing edge 101 from warping up, causing the photovoltaic panel to not be pressed tightly.
[0027] In this embodiment, the reset member 30 is a spring sleeved outside the locking member 40, with the two ends of the spring abutting against the U-shaped groove 102 and the U-shaped fixing seat 20, respectively.
[0028] In this embodiment, a horizontal plate 201 is provided between the inner walls of the two sides of the U-shaped fixing seat 20. The horizontal plate 201 divides the inner cavity of the U-shaped fixing seat 20 into an upper cavity 202 and a lower cavity 203. The two ends of the spring abut against the U-shaped groove 102 and the horizontal plate 201, respectively. Specifically, the bottom end faces of the horizontal plate 201 and the U-shaped fixing seat 20 are respectively provided with a second through hole 204 and a third through hole 205. The locking member 40 passes through the U-shaped fixing seat 20 through the second through hole 204 and the third through hole 205.
[0029] In this embodiment, the locking member 40 has a first anti-disengagement inclined surface 401 along its circumference at its head end, and the intermediate pressure seat 10 has a first through hole 103. A second anti-disengagement inclined surface 104 adapted to the first anti-disengagement inclined surface 401 is provided around the through hole. The cooperation between the first anti-disengagement inclined surface 401 and the second anti-disengagement inclined surface 104 prevents the locking member 40 from falling down from the through hole. When the locking member 40 is tightened downwards, it can drive the intermediate pressure seat 10 to move downwards.
[0030] In this embodiment, the locking block 50 is provided with a groove 502 for abutting against the inverted guide rail 70.
[0031] The working principle of the medium-voltage device for photovoltaic support proposed in this utility model is as follows:
[0032] First, assemble the intermediate pressure device: place the spring on the horizontal plate 201 and align it with the position of the second through hole 204. Then, place the intermediate pressure seat 10 above the fixed seat 20, so that the inner walls of both sides of the U-shaped groove 102 are in contact with the outer walls of both sides of the U-shaped fixed seat 20. At this time, the two ends of the spring abut against the U-shaped groove 102 and the U-shaped fixed seat 20 respectively. Then, insert the locking member 40 through the first through hole 103 of the intermediate pressure seat 10. The locking member 40 passes through the first through hole 103, the second through hole 204 and the third through hole 205 in sequence. The end of the locking member 40 is outside the fixed seat 20. Then, the end of the locking member 40 is threadedly connected to the threaded hole 501 of the locking block 50.
[0033] The assembled medium-pressure device is mounted on the guide rail 70, with the locking block 50 positioned within the groove at the top of the guide rail 70, and the lower end face of the fixing seat 20 abutting against the upper end face of the guide rail 70. This step can be done by referring to existing methods of mounting medium-pressure devices on the top of the guide rail 70, where the locking block 50 is slid into the guide rail 70 from the side. Alternatively, the guide rail 70 may have a notch 701 at the top, allowing a downward pressure to be applied to the medium-pressure device, causing the locking block 50 to engage with the guide rail 70 through the notch 701.
[0034] Then, the locking member 40 is adjusted. When the locking member 40 is rotated downwards, due to the presence of the first anti-disengagement inclined surface 401 and the second anti-disengagement inclined surface 104, the locking member 40 moves downwards and applies a downward pressure force to the intermediate pressure seat 10. The spring is compressed, the intermediate pressure seat 10 moves downwards, and the distance between the upper end face of the intermediate pressure seat 10 and the lower end face of the fixed seat 20 decreases. That is, the intermediate pressure seat 10 is lowered relative to the fixed seat 20, and the height of the pressing edge 101 decreases until the lower end face of the pressing edge 101 abuts against the upper end face of the photovoltaic panel, thus completing the pressing of the photovoltaic panel. If If the photovoltaic panel is too thick and the height of the pressing edge 101 is insufficient, the operation is reversed: rotate the locking part 40 upward to move the locking part 40 upward to a certain extent (but the locking part 40 still does not disengage from the threaded hole 501 of the locking block 50). Under the reset action of the spring, the intermediate pressure seat 10 moves upward, and the distance between the upper end face of the intermediate pressure seat 10 and the lower end face of the fixed seat 20 increases. That is, the intermediate pressure seat 10 is raised relative to the fixed seat 20, and the height of the pressing edge 101 rises until the lower end face of the pressing edge 101 is sufficient to abut against the upper end face of the photovoltaic panel, thus completing the pressing of the photovoltaic panel.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
