Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically a heat-dissipating low-voltage withdrawable switchgear. Background Technology

[0002] The heat-dissipating low-voltage withdrawable switchgear is an electrical device used in low-voltage power distribution systems. It features a drawer-type design for easy maintenance and operation, and is specially designed for heat dissipation to ensure safe and efficient operation of the equipment.

[0003] First, with traditional devices, if the drawer cannot be reliably secured, it may loosen during operation, potentially leading to equipment damage or electrical safety hazards.

[0004] Secondly, without the function of quickly replacing dustproof parts, dust and debris may accumulate inside the equipment, affecting the normal operation of electrical components and even causing malfunctions.

[0005] Finally, without directional heat dissipation, heat may accumulate inside the cabinet, leading to excessively high temperatures, which may in turn cause damage to electrical components or a decline in their performance. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Example 1:

[0031] Please see Figure 1 one Figure 6 A heat-dissipating low-voltage withdrawable switch cabinet includes a main body 1, a closing mechanism, and a heat dissipation mechanism. The closing mechanism includes a drawer 2, a first roller 3, a rotating handle 4, a retaining strip 5, and a dustproof mechanism. The drawer 2 is mounted on the main body 1 and slidably connected to the main body 1. The first roller 3 is mounted on the main body 1 and slidably connected to the drawer 2. The rotating handle 4 is mounted on the drawer 2 and rotatably connected to the drawer 2. The retaining strip 5 is installed inside the drawer 2 and slidably connected to the drawer 2. The dustproof mechanism includes a dustproof component 6, a first spring 7, a spring plate 8, a retaining block 9, and a second spring 10. The dustproof component 6 is mounted on the main body 1 and detachably connected to the main body 1. The first spring 7 is mounted on the drawer 2, and its other end is fixedly connected to the spring plate 8. The spring plate 8 is mounted on the drawer 2 and slidably connected to the drawer 2. The retaining block 9 is mounted on the drawer 2 and slidably connected to the drawer 2. The second spring 10 is mounted on the drawer 2, and its other end is fixedly connected to the retaining block 9.

[0032] In this embodiment, the closing mechanism includes a drawer 2, a first roller 3, a rotating handle 4, a locking strip 5, and a dustproof mechanism. During use, it is necessary to check the operation of the internal components of the drawer 2. Rotating the rotating handle 4 causes the driving gear 23 to mesh with the driven gear 22, allowing the locking strip 5 to slide in the drawer 2 and disengage from the first locking hole 21. Then, the drawer 2 is pulled, and the first roller 3 mounted on the main body 1 slides in the first slide groove 20 at the bottom of the drawer 2, while the second roller 17 mounted on the bottom of the drawer 2 simultaneously slides in the second slide groove 19 of the main body 1, making the drawer 2 easier and more convenient to pull out.

[0033] In this embodiment, the dustproof mechanism includes a dustproof component 6, a first spring 7, a spring plate 8, a locking block 9, and a second spring 10. During use, the dustproof component 6 may accumulate dust over time, resulting in excessive dust and reduced dustproof efficiency. At this time, the dustproof component 6 needs to be replaced. Pulling the locking block 9 causes it to slide on the second through rod 25 of the drawer 2 while compressing the second spring 10. This prevents the locking block 9 from limiting the second locking hole 26 of the dustproof component 6. The dustproof component 6 is then pushed by the spring plate 8, which is pushed by the compressed first spring 7. Under the action of the first through rod 24, the dustproof component 6 can stably detach from the drawer 2 due to the force of the spring plate 8. The first through rod 24 is also pulled out of the positioning hole 27 on the dustproof component 6, allowing the dustproof component 6 to be disassembled and easily replaced.

[0034] In this embodiment, the heat dissipation mechanism includes a connector 11, a closing plate 12, a rocking rod 13, a motor 14, a ventilation box 15, and a fan 16. During use, it is necessary to dissipate heat from the electrical components inside the drawer 2. The fan 16 operates, creating a negative pressure in the ventilation box 15. The motor 14 operates, allowing the closing plate 12 mounted on the connector 11 to rotate. Under the action of the rocking rod 13, multiple closing plates 12 can rotate simultaneously, facilitating the opening of the air circulation channel between the connector 11 and the drawer 2. In special circumstances, such as different drawers 2 having different internal temperatures, the operating state of the motor 14 on each connector 11 changes, achieving independent heat dissipation for different drawers 2 and improving heat dissipation efficiency.

[0035] Example 2:

[0036] In summary, during use, if it is necessary to check the operation of the internal components of drawer 2, rotate the handle 4 to engage the drive gear 23 with the driven gear 22, allowing the locking strip 5 to slide in drawer 2 and disengage from the first locking hole 21. Then, pull drawer 2, and the first roller 3 mounted on the main body 1 slides in the first slide groove 20 at the bottom of drawer 2, while the second roller 17 mounted on the bottom of drawer 2 simultaneously slides in the second slide groove 19 of the main body 1, making the drawer 2 easier to pull out. In addition, the dustproof part 6 on drawer 2 also needs to be replaced. Pull the locking block 9, causing it to slide on the second guide rod 25 of drawer 2 while compressing the second spring 10, so that the locking block 9 no longer limits the second locking hole 26 of the dustproof part 6. At this time, the dustproof part 6 is pushed by the spring plate 8 pushed by the compressed first spring 7. Under the push, the dustproof component 6 can be stably separated from the drawer 2 by the force of the spring plate 8 under the action of the first through rod 24, and the first through rod 24 is pulled out of the positioning hole 27 on the dustproof component 6, so that the dustproof component 6 can be disassembled and easily replaced. When the device is dissipating heat, it is necessary to dissipate heat on the electrical components inside the drawer 2. At this time, the fan 16 runs, which generates negative pressure in the ventilation box 15. At this time, the motor 14 runs, which allows the closing plate 12 installed on the connector 11 to rotate. Under the action of the rocking rod 13, multiple closing plates 12 can rotate simultaneously, which facilitates the opening of the air circulation channel between the connector 11 and the drawer 2. In special cases, such as different internal temperatures of different drawers 2, the operating state of the motor 14 on each connector 11 changes, thus completing independent heat dissipation for different drawers 2 and improving heat dissipation efficiency.

[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
