[0033] like Figure 1-4 As shown, a photovoltaic micro-inverter fixing structure proposed in the present application includes a mounting plate 1, a plurality of mounting holes 15 are provided on the side of the mounting plate 1, and the mounting plate 1 is positioned by screws (the positioning method of the prior art is used here and will not be described in detail), a support seat 2 is connected to the lower end of the outer surface of the mounting plate 1, and a heat dissipation frame 8 located above the support seat 2 is also connected to the outer surface of the mounting plate 1, and a locking assembly 5 is installed on the upper end of the heat dissipation frame 8, and the locking assembly 5 includes an L-shaped locking plate 52 that can be raised and lowered, and a touch-tightening assembly 7 is installed on the heat dissipation frame 8, and the touch-tightening assembly 7 is driven by the locking assembly 5; a pair of clamping plates 12 are provided on the front side of the heat dissipation frame 8, and a transmission block 13 is fixedly connected to the inner surface of the clamping plate 12, and the transmission block 13 is pushed by the touch-tightening assembly 7 to resist and position the inner side of the inverter. A positioning groove 3 is provided on the upper end of the support seat 2, and the micro-inverter is placed inside the positioning groove 3 during installation. The heat dissipation frame 8 is in the shape of a circular circle, and convection grooves 9 are provided on both sides of the heat dissipation frame 8. A plurality of heat dissipation holes 10 are provided on the side of the mounting plate 1, which are used for ventilating and dissipating the back of the inverter. The two convection grooves 9 are arranged opposite to each other, so that the air can form convection and improve the heat dissipation effect.

[0034] Furthermore, the contact assembly 7 includes a slide plate 73 slidably arranged in the convection groove 9, and a pressing block 74 is fixedly connected to a side of the slide plate 73 away from the mounting plate 1. The pressing block 74 is arc-shaped. When the two pressing blocks 74 move downward, they squeeze the two transmission blocks 13 respectively, so that the two transmission blocks 13 move away from the mounting plate 1, and finally push the two clamping plates 12 toward the inverter.

[0035] Specifically, the locking assembly 5 includes a lead screw 54 rotatably connected to the upper end of the heat dissipation frame 8, an operating block is fixedly connected to the upper end of the lead screw 54, a transmission sleeve 53 is provided on the outer side of the lead screw 54, both ends of the transmission sleeve 53 are connected to an L-shaped transmission plate 51, a pair of guide plates 4 are fixedly connected to the upper end of the support seat 2, the two L-shaped transmission plates 51 are respectively slidably plugged into the upper ends of the two guide plates 4, the lower end sides of the two L-shaped transmission plates 51 are fixedly connected to the limiting slider 11, and the upper ends of the two guide plates 4 are provided with a slide groove The bottom ends of the two L-shaped transmission plates 51 are respectively slidably connected in the two slide grooves, and the inner walls of the two slide grooves are provided with limiting grooves. The two limiting sliders 11 are respectively slidably connected in the two limiting grooves to prevent the L-shaped transmission plate 51 from separating from the guide plate 4; the two L-shaped transmission plates 51 are fixedly connected with an L-shaped locking plate 52 on one side away from the mounting plate 1, which is used to limit and fix the inverter; the inner corner of the lower end of the L-shaped locking plate 52 is set to an arc-shaped portion 6 to reduce friction during positioning, so that the lower end of the L-shaped locking plate 52 can be smoothly clamped on the outside of the inverter.

[0036] The transmission block 13 slides through the front surface of the heat dissipation frame 8 and extends into the convection groove 9. The upper end of the transmission block 13 near the slide plate 73 is set to an arc surface 14, so that when the slide plate 73 moves downward, the pressing block 74 can smoothly push the transmission block 13. The lower end of the transmission block 13 near the slide plate 73 is fixedly connected to a limiting protrusion 16, which is used to limit and prevent the transmission block 13 from detaching from the heat dissipation frame 8. A connecting plate 71 is connected between the two slide plates 73, and the connecting plate 71 is connected to the L-shaped transmission plate 51 through a transmission rod 72. The two transmission rods 72 both slide through the upper surface of the heat dissipation frame 8, and when the lead screw 54 is rotated, the L-shaped transmission plate 51 and the two slide plates 73 can be synchronously driven to move downward.

[0037] The specific working principle is as follows: when installing the micro inverter, first install the mounting plate 1 at the designated position, and fix the mounting plate 1 by screws penetrating the mounting holes 15. Then place the inverter in the positioning groove 3, the thickness of the inverter is smaller than the front-to-back width of the support seat 2 (the inverter can be smoothly placed in the positioning groove 3), and then rotate the lead screw 54, the lead screw 54 rotates to drive the transmission sleeve 53 to move downward, thereby driving the two L-shaped transmission plates 51 to move downward, and the two L-shaped transmission plates 51 move downward to drive the two L-shaped locking plates 52 to move downward, so that the outer ends of the two L-shaped locking plates 52 drop to the outer side of the upper end of the inverter, and the upper end of the inverter is positioned. When the two L-shaped transmission plates 51 move downward, they also drive the two transmission rods 72 to move downward. The two transmission rods 72 move downward to push the connecting plate 71 to move downward. The connecting plate 71 moves downward to drive the two slide plates 73 to move downward. Finally, the two pressing blocks 74 squeeze the two transmission blocks 13, so that the two transmission blocks 13 move away from the mounting plate 1, and further drive the two clamping plates 12 to move away from the mounting plate 1 and abut against the inner surface of the inverter. Under the joint action of the positioning groove 3 and the L-shaped locking plate 52, the inverter is positioned and fixed in all directions. The whole process is simple to operate and can prevent the loosening of components after installation.
