Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model discloses a distributed energy storage high-voltage control cabinet, including a cabinet 1, and further including: a cooling fan 2 and a dustproof net 3 disposed on one side of the cabinet 1. The cooling fan 2 is arranged in an array of multiple units, and the dustproof net 3 is connected to the cooling fan 2.

[0022] A fixed frame 4 is installed inside the cabinet 1. Multiple cooling elements 5 are installed inside the fixed frame 4.

An adjustment device is installed on the fixed frame 4. The adjustment device is used to adjust the cooling elements 5 to be close to the heat source. A drying device is installed on the surface of the adjustment device.

[0023] Specifically, the drive device includes a drive motor 8, a lead screw 9, and a drive block 10. The drive motor 8 is fixedly installed on the top of the cabinet 1. The lead screw 9 is installed inside the cabinet 1 on one side. One end of the lead screw 9 is fixedly connected to the output shaft of the drive motor 8. The drive block 10 is fixedly installed on the side of the fixed frame 4. The drive block 10 is threaded onto the surface of the lead screw 9. A guide rod for guiding the fixed frame 4 is provided on the other side inside the cabinet 1.

[0024] In this embodiment, multiple temperature sensors 7 are installed in multiple areas inside the cabinet 1 to monitor the temperature of multiple areas of the cabinet 1. When the temperature of one area is too high, one of the temperature sensors 7 drives the drive motor 8 through the controller. The output shaft of the drive motor 8 drives the lead screw 9 to rotate. The lead screw 9 drives the drive block 10 to move through the thread. The drive block 10 drives the fixed frame 4 to move. At the same time, the guide rod guides the fixed frame 4, so that the fixed frame 4 drives the cooling element 5 to adjust to the position of the excessively high temperature for heat dissipation, thereby enabling heat dissipation in the position of severe heat generation.

[0025] Specifically, the adjustment device includes an adjustment frame 11 and an electric push rod 12. The fixed frame 4 has multiple through holes arranged in a longitudinal array. The adjustment frame 11 is adapted to the shape of the fixed frame 4 and is located on one side of the fixed frame 4. The electric push rod 12 is fixedly installed on the surface of the fixed frame 4 and its telescopic end is fixedly connected to the adjustment frame 11. The cooling plate 5 is fixedly installed in the through holes of the adjustment frame 11 and is located at the opening on the side of the adjustment frame 11 away from the fixed frame 4.

[0026] In this implementation scheme, the electric push rod 12 is activated, and the telescopic shaft of the electric push rod 12 extends to drive the adjustment frame 11 to move towards the electronic components. At the same time, the adjustment frame 11 drives the bellows 21 to stretch, so that the adjustment frame 11 can drive the cooling chip 5 to get closer to the electronic components, thereby further improving the heat dissipation effect.

[0027] Specifically, the drying device includes a hinge seat 13, a swing rod 14, a moisture-absorbing component 15, and a rotary motor 16. The hinge seat 13, the swing rod 14, and the moisture-absorbing component 15 are all adapted to the number of cooling chips 5. The hinge seat 13 is fixedly installed on the top surface of the adjusting frame 11. The connecting shaft of the swing rod 14 is inserted into the hinge seat 13. The moisture-absorbing component 15 is fixedly installed on the surface of the swing rod 14 and is movably connected to the surface of the cooling chip 5. The rotary motor 16 is installed on one side of the top of the adjusting frame 11. The rotary motor 16 drives the swing rod 14 to swing through the transmission assembly.

[0028] The transmission assembly includes a drive gear 17, a transmission rack 18, and multiple driven gears 19. The drive gear 17 is fixedly sleeved on the output shaft of the rotating motor 16, and the multiple driven gears 19 are respectively fixedly sleeved on the surface of the connecting shaft of the swing rod 14. The transmission rack 18 is slidably disposed on the surface of the adjusting frame 11, and the drive gear 17 and the multiple driven gears 19 are all meshed with the transmission rack 18.

[0029] In this embodiment, by controlling the output shaft of the rotating motor 16 to reciprocate forward and reverse, the output shaft of the rotating motor 16 drives the drive gear 17 to rotate. The drive gear 17 drives the driven gear 19 to reciprocate forward and reverse through the transmission rack 18, thereby driving the swing rod 14 to swing on the hinge seat 13. The swing rod 14 drives the moisture-absorbing component 15 to move on the surface of the cooling chip 5. The moisture-absorbing component 15 is a sponge block filled with desiccant, which can absorb water droplets on the cooling chip 5 and keep it dry.

[0030] Specifically, a ventilation pipe 20 is fixedly installed on the side of the fixed frame 4 away from the adjusting frame 11. The ventilation pipe 20 is connected to multiple through holes of the fixed frame 4. The through holes of the fixed frame 4 are connected to the through holes of the adjusting frame 11 through corrugated pipes 21. A strip groove 22 is opened on one side of the cabinet 1. The dustproof net 3 is connected to the strip groove 22. The air outlet of the ventilation pipe 20 faces the strip groove 22. An exhaust fan 23 is fixedly installed at the air outlet of the ventilation pipe 20.

[0031] In this embodiment, by setting up ventilation pipe 20 and corrugated pipe 21, the heat released by heat dissipation fins 6 will enter the ventilation pipe 20 through corrugated pipe 21 and fixed frame 4. At the same time, the exhaust fan 23 in the ventilation pipe 20 will be activated, and the exhaust fan 23 will exhaust the heat in the ventilation pipe 20 to the outside of the cabinet 1 through the strip groove 22, thereby preventing heat from remaining in the cabinet 1.

[0032] Specifically, a storage groove 24 is provided on the bottom inner side of the cabinet 1, and the other end of the lead screw 9 is connected to the bearing on the bottom inner side of the storage groove 24. The storage groove 24 is used to store the fixed frame 4.

[0033] In this embodiment, the fixed frame 4 and its surface structure are driven into the storage slot 24 by the lead screw 9, so that the fixed frame 4 can be stored and will not be obstructed when repairing electronic components in the cabinet 1.

[0034] The working principle and usage process of this utility model are as follows: During use, the cooling fan 2 on the side of the cabinet 1 dissipates heat from the circuit components inside the cabinet, and the dustproof net 3 prevents dust. When the operating frequency of the electrical components inside the cabinet 1 is increased, the heat generated inside the cabinet 1 will increase. Then, the cooling plate 5 is activated. The cold end of the cooling plate 5 absorbs the heat from the electrical components, reducing the heat of the electrical components. Then, the hot end of the cooling plate 5 releases the heat, thereby improving the heat dissipation of the electrical components. The hot end of the cooling plate 5 is fixed with heat dissipation fins 6, which can accelerate the heat release. By setting up a ventilation pipe 20 and a corrugated pipe 21, the released heat will enter the ventilation pipe 20 through the corrugated pipe 21 and the fixed frame 4. At the same time, the exhaust fan 23 in the ventilation pipe 20 is activated. The exhaust fan 23 exhausts the heat in the ventilation pipe 20 to the outside of the cabinet 1 through the strip groove 22, thereby preventing heat from remaining inside the cabinet 1.

[0035] Temperature sensors 7 are installed in multiple areas inside the cabinet 1 to monitor the temperature of multiple areas of the cabinet 1. When the temperature of one area is too high, one of the temperature sensors 7 drives the drive motor 8 through the controller. The output shaft of the drive motor 8 drives the lead screw 9 to rotate. The lead screw 9 drives the drive block 10 to move through the thread. The drive block 10 drives the fixed frame 4 to move. At the same time, the guide rod guides the fixed frame 4, so that the fixed frame 4 drives the cooling element 5 to adjust to the position of the excessively high temperature for heat dissipation, thereby enabling heat dissipation in the area with severe heat generation.

[0036] Then, the electric push rod 12 is activated. The telescopic shaft of the electric push rod 12 extends and drives the adjustment frame 11 to move towards the electronic components. At the same time, the adjustment frame 11 drives the bellows 21 to stretch, so that the adjustment frame 11 can drive the cooling chip 5 to get closer to the electronic components, further improving the heat dissipation effect.
