[0002] The inverter is a converter that converts DC power into constant frequency and voltage or frequency and voltage regulated AC power. It consists of an inverter bridge, control logic and filter circuit. Photovoltaic inverters are mostly fixed on the bracket below each set of photovoltaic panels. When the current photovoltaic inverter is fixed, the inverter is installed on the bracket by bolts. When the inverter is fixed, it is not convenient to adjust the size of the mounting plate according to the size of the inverter. At the same time, through the fixing method of bolts and nuts, a large number of photovoltaic inverters need to be installed in photovoltaic power generation. When installing photovoltaic inverters in a large area, it is necessary to tighten the bolts and nuts one by one, which leads to low installation efficiency. At the same time, when disassembling, tools are required, which leads to inconvenient disassembly.

[0003] To this end, the present application designs an inverter mounting bracket to solve the above problems. Utility Model Content

[0034] Reference Figure 1-Figure 8 The mounting hole of the inverter 4 is smaller than the outer diameter of the pop-up slope block 305, and is adapted to the outer diameter of the hollow column 304 and the collar 307. The side of the slope block 305 away from the second screw 301 is a slope structure. The two vertical beams 2 are fixed under the photovoltaic panel. The two horizontal beams 1 are slidably adjusted along the two vertical beams 2. One is to adjust the height of the inverter 4, and the other is to adjust the distance between the upper and lower sets of fixing parts 3. Then the distance between the fixing parts 3 on the horizontal beam 1 is slidably adjusted, and the horizontal installation position of the inverter 4 can be adjusted. The first section is to adjust the spacing between the fixing parts 3, and then adjust the installation size, so as to fix inverters 4 of different sizes. The adjusted installation hole of the inverter 4 corresponds to the hollow column 304, and the inverter 4 is pressed toward the hollow column 304, so that the slope block 305 elastically shrinks into the hollow column 304, and when the installation hole of the inverter 4 passes through the slope block 305, the slope block 305 pops up and clamps the inverter 4, and the ring 307 is pressed toward the direction of the slope block 305 to shrink the slope block 305, and then the inverter 4 can be pulled out.

[0035] Through holes 101 are provided at both ends of the horizontal beam 1, and a T-shaped horizontal sliding groove 103 is provided horizontally on the horizontal beam 1. Fixing holes 201 are provided at both ends of the vertical beam 2, and a T-shaped vertical sliding groove 203 is provided vertically on the vertical beam 2. A vertical sliding block 206 is slidably provided in the vertical sliding groove 203, and a first screw rod 204 passing through the through hole 101 is fixed to the vertical sliding block 206, and a first nut 205 is threadedly connected to the first screw rod 204.

[0036] Reference Figure 1-Figure 4The vertical beam 2 is fixed to the support frame below the photovoltaic panel through the fixing holes 201 at both ends with the cooperation of the bolt and nut group, and then the vertical slider 206 is vertically slidably set in the vertical slide groove 203, and the first screw rod 204 passes through the through hole 101, and the first nut 205 is threadedly connected to the first screw rod 204 and abuts against the cross beam 1, so that the vertical slider 206 and the vertical slide groove 203 are slidably matched, and with the cooperation of the first screw rod 204 and the first nut 205, the two cross beams 1 are fixed after the height and / or spacing are adjusted.

[0037] The fixing member 3 also includes a second nut 302 threadedly connected to the second screw rod 301 and a horizontal sliding block 303 fixed on the second screw rod 301 and adapted to slide with the horizontal sliding groove 103. The hollow column 304 is symmetrically provided with strip holes 3042. The end of the slope block 305 away from the second screw rod 301 is fixedly installed with an axle rod 3051, and a first spring 306 is fixedly installed between multiple slope blocks 305.

[0038] Reference Figure 5-Figure 7 The slope block 305 is placed in the strip hole 3042, the horizontal sliding block 303 is adapted to slide with the horizontal sliding groove 103, and the second nut 302 is screwed and fixed on the beam 1 through the thread cooperation with the second screw rod 301, so that the fixing member 3 can be fixed after sliding adjustment along the beam 1, and the shaft rod 3051 is fixed at the lower right end of the slope block 305, and the shaft rod 3051 is rotatably set on the hollow column 304, so that the slope block 305 can deflect with the shaft rod 3051 as the axis, and the end close to the second nut 302 is received in the cavity of the hollow column 304, and under the elastic rebound action of the first spring 306, the two slope blocks 305 are elastically supported, so that the slope block 305 is always protruding from the outside of the hollow column 304.

[0039] The hollow column 304 is provided with an annular groove 3041 , and the collar 307 is placed in the annular groove 3041 . The collar 307 has the same outer diameter as the hollow column 304 .

[0040] Reference Figure 5-Figure 7 The collar 307 is placed in the annular groove 3041 of the hollow column 304 , and the collar 307 has the same outer diameter as the hollow column 304 , so as to avoid interference between the mounting hole of the inverter 4 and the collar 307 when the mounting hole is inserted into the hollow column 304 .

[0041] A limiting block 3052 disposed below the strip hole 3042 is fixedly mounted on one end of the slope block 305 away from the shaft rod 3051 .

[0042] Reference Figure 6 Under the elastic rebound action of the first spring 306 , the limit block 3052 abuts against the inner wall of the hollow column 304 to limit the slope block 305 , thereby preventing the slope block 305 from deflecting outward in a transitional manner and escaping from the strip hole 3042 .

[0043] The second screw rod 301 is threadedly connected with the third nut 308 . A ring 3082 is sleeved on the second screw rod 301 . A second spring 3081 disposed between the third nut 308 and the ring 3082 is sleeved on the second screw rod 301 .

[0044] Reference Figure 5-Figure 7 By adjusting the third nut 308 to adjust the positions of the ring 3082 and the second spring 3081, the ring 3082 is made to rest against the side of the mounting plate of the inverter 4 away from the slope block 305, so as to improve the installation stability of the inverter 4 through the elastic support of the second spring 3081. At the same time, when the inverter 4 is in a horizontal installation state, the second spring 3081 can also play a shock-absorbing role.

[0045] A first mounting opening 102 communicating with the horizontal sliding groove 103 is formed at one end of the horizontal beam 1 , and a second mounting opening 202 communicating with the vertical sliding groove 203 is formed at one end of the vertical beam 2 .

[0046] Reference Figure 2 and Figure 3 The first mounting port 102 is adapted to the horizontal slider 303, and the horizontal slider 303 of the fixing member 3 is disassembled and assembled through the first mounting port 102 to facilitate the adjustment of the installation quantity of the fixing member 3, and the second mounting port 202 is adapted to the vertical slider 206 to facilitate the disassembly and assembly of the first screw rod 204 and the vertical beam 2.

[0047] Working principle: The vertical beam 2 is fixed to the support frame below the photovoltaic panel through the fixing holes 201 at both ends with the cooperation of the bolt and nut group. The vertical slider 206 is adjusted by vertical sliding in the vertical slide groove 203 to adjust the height or spacing of the two horizontal beams 1. Then, the first road surface 205 is rotated clockwise to fix the horizontal beam 1 on the vertical beam 2. Then, the horizontal slider 303 on the horizontal beam 1 is slid along the horizontal slide groove 103 to adjust the spacing of the fixing member 3 on the horizontal beam 1. The fixing member 3 corresponds to the installation hole of the inverter 4. The collar 307 is placed on the hollow column 304. Without squeezing the slope block 305, the mounting hole of the inverter 4 is inserted into the hollow column 304, and under the action of the slope surface of the slope block 305, the slope block 305 is compressed into the hollow column 304, and the first spring 306 elastically contracts. Then, when the mounting hole is separated from the slope block 305, the first spring 306 elastically rebounds, and the slope block 305 is reset to clamp the inverter 4. When disassembling, press the ring 307 in the direction of the slope block 305, the slope block 305 is contracted in the hollow column 304 and squeezed by the ring 307, and the inverter 4 can be quickly removed from the four sets of fixing parts 3.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
