Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage switch cabinets, in particular to a novel low-voltage switch cabinet. Background Art

[0002] With the improvement of the domestic power construction level, the low-voltage electrical industry has also continued to develop rapidly. Low-voltage switchgear is also a commonly used equipment in power construction and development. Low-voltage switchgear is suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries for transmission, distribution and power conversion.

[0003] However, most of the current switch cabinets only rely on the ventilation grilles for basic heat dissipation. When the weather is hot and the temperature is high, the heat dissipation capacity is seriously insufficient, affecting the safe use of internal electrical components.

[0004] Based on this, the utility model designs a novel low-voltage switch cabinet to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of low-voltage switch cabinet to solve the above technical problems.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of low-voltage switch cabinet, comprising: a switch cabinet; two symmetrical fans are fixedly connected to the top of the switch cabinet, two exhaust pipes connected to the fans are fixedly connected to the top of the switch cabinet, a motor is fixedly connected to the top of the switch cabinet, a connecting plate is fixedly connected to the end of the motor shaft, and two symmetrical protective covers are fixedly connected to the outer wall of the connecting plate.

[0007] Preferably, one end of the discharge pipe is magnetically connected to a magnetic ring, one end of the magnetic ring is fixedly connected to a placement ring, and the inner ring wall of the placement ring is fixedly connected to a filter screen.

[0008] Preferably, two symmetrical auxiliary blocks are fixedly connected to the outer wall of the placement ring.

[0009] Preferably, a ventilation grille is provided on the outer wall of the switch cabinet.

[0010] Compared with the prior art, the utility model has the following beneficial effects: two fans are added on the top of the switch cabinet. When the weather is hot and the temperature is high, the high-temperature airflow in the switch cabinet can be drawn out through the two fans and discharged through the exhaust pipe, thereby improving the heat dissipation capacity and safety of the switch cabinet;

[0011] When the fan is not running, the two protective covers can be quickly moved under the control of the motor to block the outlet of the exhaust pipe for protection, preventing dust and impurities from falling in and contaminating the fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a new type of low-voltage switch cabinet, comprising: a switch cabinet 1; two symmetrical fans 2 are fixedly connected to the top of the switch cabinet 1, two exhaust pipes 4 connected to the fans 2 are fixedly connected to the top of the switch cabinet 1, a motor 8 is fixedly connected to the top of the switch cabinet 1, a connecting plate 9 is fixedly connected to the end of the rotating shaft of the motor 8, and two symmetrical protective covers 10 are fixedly connected to the outer wall of the connecting plate 9;

[0021] Two fans 2 are added on the top of the switch cabinet 1. When the weather is hot and the temperature is high, the two fans 2 can draw out the high-temperature airflow in the switch cabinet 1 and discharge it through the exhaust pipe 4, thereby improving the heat dissipation capacity of the switch cabinet 1. When the fans 2 are not running, two protective covers 10 controlled by the motor 8 can be used to block the outlet of the exhaust pipe 4 to prevent dust and impurities from falling in and adhering to and polluting the fans 2.

[0022] Preferably, one end of the discharge pipe 4 is magnetically connected to a magnetic ring 6, one end of the magnetic ring 6 is fixedly connected to a placement ring 5, and the inner wall of the placement ring 5 is fixedly connected to a filter screen 11;

[0023] The filter screen 11 of the placement ring is used at one end of the discharge pipe 4 to protect the fan 2 during operation to prevent large pieces of objects from falling into and affecting the fan 2. The placement ring 5 is stably placed at one end of the discharge pipe 4 using the magnetic ring 6 at one end thereof, and can be quickly disassembled and assembled.

[0024] Preferably, the outer wall of the placement ring 5 is fixedly connected to two symmetrical auxiliary blocks 7;

[0025] The auxiliary block 7 is used to facilitate personnel to disassemble and assemble the placement ring 5.

[0026] Preferably, a ventilation grille 3 is provided on the outer wall of the switch cabinet 1;

[0027] The ventilation grille 3 ensures the basic ventilation and heat dissipation capability of the switch cabinet 1 .

[0028] A specific application of this embodiment is: the switch cabinet 1 is usually ensured to have basic ventilation and heat dissipation by the ventilation grille 3. When the weather is hot and the temperature is high, the connection plate 9 can be controlled to rotate by the motor 8, and the two protective covers 10 can be driven to rotate at the same time, so that the two protective covers 10 leave one end of the mounting ring 5, so that the exhaust pipe 4 can be kept unobstructed, and then the two fans 2 are operated to extract the high-calorie gas in the switch cabinet, speed up the air flow rate in the switch cabinet 1, and quickly discharge the heat from the switch cabinet 1 through the exhaust pipe 4. When the switch cabinet 1 is not in use, the motor 8 can be used to control the two protective covers 10 to rotate again and block one end of the mounting ring 5, thereby preventing dust and impurities from falling onto the filter 11 or the fan blades of the fan 2 to cause an impact.
