Description

Technical Field

[0001] This utility model relates to the field of photovoltaic inverter integrated machine technology, specifically to a structure for preventing loosening of the connection between the photovoltaic inverter integrated machine and the bracket. Background Technology

[0002] In photovoltaic power plant systems, the photovoltaic inverter unit, as the core equipment for converting direct current to alternating current, has a connection stability with the support structure that directly affects the safe operation and power generation efficiency of the equipment.

[0003] Photovoltaic inverters generate continuous vibration during operation and are exposed to the outdoor environment for extended periods, requiring them to withstand external forces such as strong winds and temperature changes. Traditional connection structures are unable to withstand the effects of these factors, posing significant safety hazards. Existing photovoltaic inverters are mostly connected to the brackets by bolts, which has a fundamental flaw: vibration will cause the bolts to gradually loosen. Initially, this manifests as slight shaking of the equipment. As the gap increases, the vibration amplitude intensifies, further accelerating bolt wear. Ultimately, this may cause the inverter to detach from the bracket, resulting in equipment damage (and power generation interruption). Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a structure to prevent loosening of the connection between the photovoltaic inverter integrated machine and the bracket, which solves the problem that the existing photovoltaic inverter integrated machine is usually connected to the corresponding bracket with bolts. However, the photovoltaic inverter integrated machine will vibrate during operation, which will cause the bolts to loosen, resulting in the photovoltaic inverter integrated machine shaking or even falling off the surface of the bracket.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A photovoltaic inverter integrated unit and bracket connection anti-loosening structure includes two L-shaped brackets. Each L-shaped bracket has a T-shaped groove at its upper end.

[0009] Preferably, the fixing mechanism includes two fixing rods, two fixing blocks, multiple first trapezoidal blocks, two second trapezoidal blocks, two lead screws, two knobs, and multiple T-shaped blocks. The two fixing rods are respectively inserted into the interior of corresponding strip grooves. One end of each of the two strip grooves has a square groove. The two fixing blocks are respectively disposed inside the corresponding square grooves and are respectively fixedly connected to one end of the corresponding fixing rod. The surface of each of the two fixing blocks has a second sliding groove. One side of each of the two second sliding grooves has a second internal threaded hole.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model discloses a structure for preventing loosening when connecting an integrated photovoltaic inverter to a bracket.

[0029] This utility model provides, for example Figure 1-5 The photovoltaic inverter integrated unit and bracket connection anti-loosening structure shown includes two L-shaped brackets 1. The upper end of each L-shaped bracket 1 is provided with a T-shaped sliding groove. A T-shaped positioning block 2 is slidably arranged inside each T-shaped sliding groove. The photovoltaic inverter integrated unit body 3 is fixedly connected to one side of the two T-shaped positioning blocks 2. An adjustment mechanism is provided between the two L-shaped brackets 1. Two plug blocks 4 are fixedly connected to the lower surface of the photovoltaic inverter integrated unit body 3. The upper surface of each L-shaped bracket 1 is provided with two slots. Each plug block 4 is inserted into the corresponding slot. The interior of each L-shaped bracket 1 is provided with a strip groove. The interior of each strip groove is provided with a fixing mechanism. Each plug block 4 is fixed by the corresponding fixing mechanism.

[0030] During installation, the photovoltaic inverter unit 3 slides along the T-shaped groove of the L-shaped bracket 1 via the T-shaped positioning blocks 2 on both sides, allowing the insert block 4 on the lower surface of the unit to be precisely inserted into the slot of the L-shaped bracket 1, thus forming initial positioning. The cooperation between the T-shaped positioning block 2 and the T-shaped groove restricts the horizontal displacement of the unit, while the insert block 4 and the slot further constrain the shaking of the unit, providing a stable foundation for subsequent fixing.

[0031] To make the device compatible with photovoltaic inverter integrated units of different sizes, such as Figure 1-3 As shown, the adjustment mechanism includes a first support rod 5, a second support rod 6, and a pin 7. The first support rod 5 and the second support rod 6 are respectively fixedly connected to one side of the corresponding L-shaped bracket 1. A first sliding groove is provided on one side of the first support rod 5. The second support rod 6 is inserted into the inside of the first sliding groove. A first internal threaded hole is provided on the upper surface of one end of the sliding groove. The pin 7 is threaded inside the internal threaded hole. One end of each of the two pins 7 is threaded, and the two threads are respectively matched with the corresponding first internal threaded holes. A plurality of second insertion holes are provided on the surface of the second support rod 6, and each second insertion hole is matched with the corresponding pin 7.

[0032] When the L-shaped bracket 1 is pushed, the second support rod 6 slides along the first groove of the first support rod 5, changing the bracket spacing. When the spacing is suitable, the pin 7 is screwed into the first internal threaded hole and inserted into the corresponding second insertion hole of the second support rod 6. The bracket spacing is fixed by thread locking and pin limiting, ensuring that the bracket and inverter body are dimensionally matched.

[0033] In order to fix the two plugs, such as Figure 1-5As shown, the fixing mechanism includes two fixing rods 8, two fixing blocks 9, multiple first trapezoidal blocks 10, two second trapezoidal blocks 11, two lead screws 12, two knobs 13, and multiple T-shaped blocks 14. The two fixing rods 8 are respectively inserted into the interior of corresponding strip grooves. One end of each of the two strip grooves has a square groove. The two fixing blocks 9 are respectively disposed inside the corresponding square grooves and fixedly connected to one end of the corresponding fixing rod 8. The surfaces of both fixing blocks 9 have second sliding grooves, and one side of each of the two second sliding grooves has a second internal threaded hole. The two lead screws 12 are respectively threaded into the interior of the corresponding second internal threaded holes. Each first trapezoidal block 10 slides... The two first trapezoidal blocks 10 are slidably set inside the corresponding second slide groove. The inclined surfaces of the two first trapezoidal blocks 10 are each provided with a T-shaped groove. The two T-shaped blocks 14 are slidably set inside the corresponding T-shaped grooves. The two second trapezoidal blocks 11 are respectively fixedly connected between the corresponding two T-shaped blocks 14. The two lead screws 12 are respectively rotatably connected to one side of the corresponding second trapezoidal block 11. The two knobs 13 are respectively fixedly connected to one side of the corresponding lead screw 12. The inner walls of the two square grooves are symmetrically provided with two fixing grooves. The two fixing grooves are respectively matched with the corresponding first trapezoidal blocks 10. Each plug 4 has a second insertion hole on one side. Each second insertion hole is respectively matched with the corresponding fixing rod 8.

[0034] When the fixed block 9 moves, it drives the fixed rod 8 to slide along the strip groove, eventually inserting it into the second insertion hole of the plug 4, rigidly locking the plug 4 and the L-shaped bracket 1. Rotating the knob 13 drives the lead screw 12 to rotate in the second internal thread hole of the fixed block 9. The lead screw 12 pushes the second trapezoidal block 11 to move along the second slide groove, and the limiting block 15 slides in the limiting groove to ensure stable movement. The second trapezoidal block 11 cooperates with the T-shaped groove of the first trapezoidal block 10 through the T-shaped block 14, pushing the first trapezoidal blocks 10 on both sides to slide and embed into the fixed groove of the square groove, so that the fixed block 9 and the inner wall of the square groove form a rigid connection. This double locking structure of "trapezoidal block fitting + fixed rod insertion" can resist the continuous vibration during the operation of the photovoltaic inverter and avoid the loosening problem of traditional bolt connections.

[0035] To facilitate the rotation of knob 13, such as Figure 2 and Figure 4 As shown, a hexagonal groove is provided on one side of each of the two knobs 13.

[0036] The hexagonal groove allows workers to easily turn knob 13 using an internal hex wrench.

[0037] In order for the second trapezoidal block 11 to move stably, such as Figure 2 and Figure 4 As shown, the inner walls of the two second slide grooves are provided with limit grooves, and the inner wall of each limit groove is provided with a limit block 15. Each limit block 15 is fixedly connected to one side of the corresponding second trapezoidal block 11.

[0038] The two second trapezoidal blocks 11 can be moved stably by using the limiting block 15.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
