[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-3 As shown, a photovoltaic inverter-boost integrated unit includes a base plate 1. Fixing plates 11 are fixedly connected to the left and right sides of the top of the base plate 1. Shock-absorbing mechanisms 2 are rotatably connected to the front and rear sides of the base plate 1. A fixing mechanism 3 is fixedly connected to the top of the shock-absorbing mechanism 2. An integrated unit housing 4 overlaps the inner wall of the fixing mechanism 3. A heat dissipation mechanism 5 is fixedly connected to the top of the integrated unit housing 4. The shock-absorbing mechanism 2 includes two rotating rods 21 and four dampers 28. The outer wall of the rotating rods 21 is rotatably connected to the inner wall of the base plate 1. The fixing mechanism 3 includes a placement frame 3. 1. The bottom end of the placement frame 31 is fixedly connected to the top end of the damper 28. The bottom end of the inner cavity of the placement frame 31 overlaps with the bottom end of the integrated machine housing 4. The left and right sides of the inner cavity of the integrated machine housing 4 are fixedly connected with partitions. The inner cavity of the integrated machine housing 4 and the partitions form an inverter box 41, a transformer box 42 and a high voltage box 43 respectively. The doors of the inverter box 41, the transformer box 42 and the high voltage box 43 are all fixedly connected with heat dissipation windows. The heat dissipation mechanism 5 includes a fixed box 51. The bottom end of the fixed box 51 is fixedly connected to the top end of the integrated machine housing 4.

[0027] The integrated chassis 4 is fixed by the fixing mechanism 3. When the integrated chassis 4 is transported, the shock absorption mechanism 2 provides shock absorption protection to prevent damage to the integrated chassis 4 during transportation. When the integrated chassis 4 is in operation, the heat dissipation mechanism 5 dissipates heat from the internal cavity of the integrated chassis 4.

[0028] like Figures 2-4As shown, the top of the rotating rod 21 is fixedly connected to the active bevel tooth 22, the top of the active bevel tooth 22 is engaged with the driven bevel tooth 23, and the axis of the driven bevel tooth 23 is fixedly connected to the bidirectional threaded rod 24. One end of the bidirectional threaded rod 24 is rotatably connected to the outer wall of the fixed plate 11, and the left and right sides of the outer wall of the bidirectional threaded rod 24 are threadedly connected to the slider 241.

[0029] By rotating the rotating rod 21, the active bevel gear 22 is driven to rotate synchronously, so that the active bevel gear 22 meshes with the driven bevel gear 23. The driven bevel gear 23 drives the bidirectional threaded rod 24 to rotate, so that the slider 241 slides on the outer wall of the bidirectional threaded rod 24.

[0030] like Figure 2 , Figure 3 As shown, a damper 25 is rotatably connected to the top of the slider 241, a spring 26 is fixedly connected to the bottom of the inner cavity of the damper 25, and a movable rod 27 is rotatably connected to the top of the damper 25.

[0031] When slider 241 slides, it drives damper 25 to move synchronously. Damper 25 drives movable rod 27 to rotate, causing connecting block 29 to slide on the outer wall of slide rod 32. This changes the distance between placement frame 31 and base plate 1, causing the shock absorption range to change. This can better protect the integrated chassis 4 and achieve the effect of adjusting the shock absorption range.

[0032] like Figure 2 , Figure 3 , Figure 5 As shown, the bottom of the movable rod 27 is rotatably connected to the bottom of the damper 28. The bottom of the inner cavity of the damper 28 is fixedly connected to the spring 281. The top of the movable rod 27 is rotatably connected to the connecting block 29. The top of the connecting block 29 is fixedly connected to the guide block 291. The outer wall of the guide block 291 is slidably connected to the bottom of the placement frame 31. The inner wall of the connecting block 29 is movably sleeved with the slide rod 32. The top of the slide rod 32 is fixedly connected to the bottom of the placement frame 31.

[0033] When transporting the integrated chassis 4, if it encounters bumps, the placement frame 31 moves downward, causing the second damper 28 to contract. This causes the second spring 281 to contract synchronously, and the placement frame 31 drives the slide rod 32 to move downward synchronously, causing the connecting block 29 to slide on the outer wall of the slide rod 32. The connecting block 29 drives the guide block 291 to slide synchronously at the bottom of the placement frame 31. The guide block 291 limits and guides the connecting block 29, making the sliding of the connecting block 29 more stable. When the connecting block 29 slides, it drives the movable rod 27 to rotate. The movable rod 27 drives the first damper 25 and the first spring 26 to contract, thereby reducing shock and reducing the impact force generated during bumps. This reduces the damage to the integrated chassis 4 and achieves the effect of shock absorption.

[0034] like Figure 2, Figure 3 As shown, threaded rods 33 are threadedly connected to both the left and right sides of the placement frame 31. One end of the threaded rod 33 is rotatably connected to a clamping plate 34. The outer wall of the clamping plate 34 overlaps with the outer wall of the integrated machine housing 4. Guide rods 35 are fixedly connected to both the front and rear ends of one end of the clamping plate 34. The outer wall of the guide rod 35 is slidably connected to the top of the placement frame 31.

[0035] Place the integrated chassis 4 into the placement frame 31, then rotate the threaded rod 33 to slide on the outer wall of the placement frame 31, causing the clamping plate 34 to move synchronously. The clamping plate 34 then causes the guide rod 35 to slide synchronously on the inner wall of the threaded rod 33. The guide rod 35 guides the clamping plate 34 so that it does not deviate when sliding. When the outer wall of the clamping plate 34 is pressed against the outer wall of the integrated chassis 4, the rotation of the threaded rod 33 can be stopped, thereby fixing the integrated chassis 4 and achieving the effect of fixation.

[0036] like Figure 2 As shown, a grid plate 53 is fixedly connected to the bottom of the inner cavity of the fixed box 51. The bottom end of the grid plate 53 overlaps with the top end of the integrated machine housing 4. A heat dissipation plate 52 overlaps in the middle of the inner cavity of the fixed box 51. A blower 54 is fixedly connected to the middle of the top end of the fixed box 51. Pipes 55 are fixedly connected to both the input end and the output end of the blower 54. The outer wall of the pipe 55 at the input end penetrates the outer wall of the fixed box 51 and extends to the inner cavity of the fixed box 51.

[0037] The heat dissipation plate 52 absorbs the heat emitted from the inverter box 41, transformer box 42 and high voltage box 43, preventing the temperature inside the inverter box 41, transformer box 42 and high voltage box 43 from becoming too high. Then, the blower 54 is started, and the heat on the heat dissipation plate 52 is carried away and blown out through the pipe 55 located at the input end, thereby achieving the heat dissipation effect.

[0038] The working principle of this utility model is as follows: In use, the integrated machine housing 4 is placed inside the placement frame 31. Then, the threaded rod 33 is rotated, causing it to slide on the outer wall of the placement frame 31. This causes the clamping plate 34 to move synchronously, and the clamping plate 34 causes the guide rod 35 to slide synchronously on the inner wall of the threaded rod 33. The guide rod 35 guides the clamping plate 34, preventing it from shifting during sliding. When the outer wall of the clamping plate 34 is pressed against the outer wall of the integrated machine housing 4, the rotation of the threaded rod 33 can be stopped, thus fixing the integrated machine housing 4 and achieving a fixing effect. Subsequent... When transporting the integrated chassis 4, if it encounters bumps, the placement frame 31 moves downward, causing the damper 28 to contract. This causes the spring 281 to contract synchronously, and simultaneously the placement frame 31 moves the slide rod 32 downward, causing the connecting block 29 to slide on the outer wall of the slide rod 32. The connecting block 29 then drives the guide block 291 to slide synchronously at the bottom of the placement frame 31. The guide block 291 limits and guides the connecting block 29, making its sliding smoother. When the connecting block 29 slides, it drives the movable rod 27 to rotate, and the movable rod 27 causes the damper 25 and the spring 26 to contract. The compression reduces vibration, thereby decreasing the impact force generated during bumps and reducing damage to the integrated chassis 4. The vibration damping range can be adjusted as needed. Rotating the rotating rod 21 drives the active bevel gear 22 to rotate synchronously, causing it to mesh with the driven bevel gear 23. The driven bevel gear 23 drives the bidirectional threaded rod 24 to rotate, causing the slider 241 to slide on the outer wall of the bidirectional threaded rod 24. The slider 241 drives the damper 25 to move synchronously, and the damper 25 drives the movable rod 27 to rotate, causing the connecting block 29 to move outside the slide rod 32. The wall slides, thereby changing the distance between the placement frame 31 and the base plate 1, which changes the shock absorption range. This better protects the all-in-one cabinet 4 and achieves the effect of adjusting the shock absorption range. Subsequently, the heat sink 52 absorbs the heat emitted from the inverter box 41, transformer box 42 and high voltage box 43 to prevent the temperature inside the inverter box 41, transformer box 42 and high voltage box 43 from getting too high. Then, the blower 54 is started, and the heat on the heat sink 52 is carried away and blown out through the pipe 55 located at the input end, thereby achieving heat dissipation and greatly improving the user experience.
