Technical Field

[0001] This utility model relates to the field of control cabinet technology, specifically a control cabinet that can prevent rain and snow accumulation. Background Technology

[0002] Control cabinets come in many types, including electrical control cabinets, frequency converter control cabinets, low-voltage control cabinets, high-voltage control cabinets, water pump control cabinets, battery control cabinets, explosion-proof control cabinets, elevator control cabinets, PLC control cabinets, fire control cabinets, brick machine control cabinets, etc. They are devices that assemble switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in enclosed or semi-enclosed metal cabinets or panels according to electrical wiring requirements. Their layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected by manual or automatic switches. In case of fault or abnormal operation, the circuit can be cut off or an alarm can be triggered by protective electrical appliances.

[0003] Currently, traditional control cabinets often have a sloping roof to reduce the accumulation of rain and snow on top. However, in low temperatures, rain and snow in contact with the roof can easily freeze and form an ice layer, making it difficult for the ice to slide off. This ice accumulates on the top of the control cabinet, which can affect electrical performance and the lifespan of the equipment, thus making the use of the control cabinet more inconvenient. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a control cabinet that can prevent rain and snow accumulation, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control cabinet that can prevent rain and snow accumulation, comprising a cabinet body, a cabinet door, and a roof, wherein the front end of the cabinet body is connected to the cabinet door via a hinge, and the top of the cabinet body is provided with a roof;

[0006] A guide spring mechanism is provided between the ceiling and the cabinet. The guide spring mechanism includes a guide frame, a guide plate, and a return spring A. The guide frame is located at the bottom of the ceiling. A heating mechanism is located at the top of the inner side of the ceiling. The heating mechanism includes a support frame, a heat-conducting plate, and a heating wire assembly. The support frame is located at the top of the inner side of the ceiling, and the heating wire assembly is installed inside the support frame. A switch trigger mechanism is provided between the ceiling and the cabinet. The switch trigger mechanism includes a contact block A, a contact block B, a battery, a housing, a top plate, and a return spring B. The housing is located at the top of the cabinet, and the contact block B is located inside the housing. The top of the inner side of the ceiling is located at the top, and the contact block A is located at the bottom of the top plate.

[0007] Preferably, the guide plate is located at the top of the cabinet, and a return spring A is connected between the guide plate and the guide frame.

[0008] Preferably, the guide plate and the guide frame form an elastic structure through a return spring A, and the guide frame is configured as an inverted "T" shape.

[0009] Preferably, the support frame is configured as a U-shaped structure, and a power line that penetrates the top plate connects the heating wire assembly and the contact block A.

[0010] Preferably, a battery connected to the contact block B via a power cable is installed at the bottom of the inner side of the housing, and symmetrically arranged reset springs B are connected between the top plate and the housing. The top plate is configured as an inverted "T" shape.

[0011] Preferably, the top plate has symmetrical guide holes on both sides, and the box body has symmetrical guide rods through the guide holes on both sides. The top plate and the box body form a sliding structure through the guide rods and guide holes.

[0012] Preferably, the top of the canopy is provided with diversion channels at equal intervals, and both the canopy and the diversion channels are configured as "V" shaped structures.

[0013] In summary, the present invention has the following main advantages:

[0014] This utility model incorporates a guide rebound mechanism, a switch triggering mechanism, and a heating mechanism. Since the roof and cabinet are slidably connected via guide plates and guide frames, and elastically connected via return spring A, when rain or snow falls to a certain amount, the roof and guide plates move vertically downwards. This causes return springs A and B to contract under force, and simultaneously, the top plate moves downwards, bringing contact block A into contact with contact block B. This creates a closed circuit between the battery, contact block B, contact block A, and the heating wire assembly, allowing the heating wire assembly to receive the necessary electrical energy and begin heating. Simultaneously, the heat is evenly transferred to the roof via a heat-conducting plate, melting the rain and snow at its top and preventing icing. This also allows the rain and snow to slide smoothly off the roof, preventing accumulation at the top of the control cabinet and thus avoiding any impact on electrical performance and equipment lifespan. This makes the control cabinet more convenient to use, and the entire process of preventing rain, snow, icing, and accumulation requires no manual intervention, achieving automated control.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] A control cabinet that can prevent rain and snow accumulation, such as Figure 1 As shown, the cabinet includes a cabinet body 1, a cabinet door 2, and a canopy 3. The front end of the cabinet body 1 is connected to the cabinet door 2 via a hinge. The top of the cabinet body 1 is provided with a canopy 3. The top of the canopy 3 is provided with diversion channels 4 at equal intervals. Both the canopy 3 and the diversion channels 4 are designed with a "V" shape structure, which can guide rain and snow to slide off, further improving the effect of preventing rain and snow from accumulating.

[0023] See Figures 1-4It is known that a guide spring mechanism 5 is provided between the ceiling 3 and the cabinet 1. The guide spring mechanism 5 includes a guide frame 501, a guide plate 502, and a return spring A503. The guide frame 501 is located at the bottom of the ceiling 3, and the guide plate 502 is located at the top of the cabinet 1. A return spring A503 connects the guide plate 502 and the guide frame 501. The guide plate 502 and the guide frame 501 form an elastic structure through the return spring A503. The guide frame 501 is configured as an inverted "T" shape. A heating mechanism 6 is provided at the top inner side of the ceiling 3. The heating mechanism 6 includes a support frame 601, a heat-conducting plate 602, and a heating wire assembly 603. The support frame 601 is located at the top inner side of the ceiling 3, and the heating wire assembly 603 is installed inside the support frame 601. The support frame 601 is configured as a U-shape. The structure includes a power line that passes through the top plate 705 and connects the heating wire assembly 603 and the contact block A701. A switch triggering mechanism 7 is provided between the ceiling 3 and the cabinet 1. The switch triggering mechanism 7 includes contact block A701, contact block B702, battery 703, housing 704, top plate 705, and reset spring B706. The housing 704 is located at the top of the cabinet 1. Contact block B702 is located on the inner side of the housing 704. The top plate 705 is located at the top of the inner side of the ceiling 3. Contact block A701 is located at the bottom of the top plate 705. The battery 703, which is connected to contact block B702 via a power line, is installed at the bottom of the inner side of the housing 704. Reset springs B706 are symmetrically arranged between the top plate 705 and the housing 704. The top plate 705 is designed with an inverted "T" shape.

[0024] See Figures 1-4 As can be seen, since the roof 3 and the cabinet 1 are slidably connected by the guide plate 502 and the guide frame 501, and elastically connected by the return spring A503, when rain and snow fall to a certain amount, the roof 3 and the guide plate 502 move vertically downward, causing the return spring A503 to contract under force. At the same time, the top plate 705 moves downward and the contact block A701 contacts the contact block B702, so that the battery 703, the contact block B702, the contact block A701 and the heating wire group 603 form a closed circuit, so that the heating wire group 603 receives the required electrical energy and starts heating. At the same time, the heat is evenly transferred to the roof 3 through the heat conduction plate 602 so that the rain and snow on its top melt, preventing icing, and allowing the rain and snow to slide smoothly off the roof 3, thus preventing the accumulation of rain and snow on the top of the control cabinet, thereby preventing the impact on electrical performance and the service life of the equipment. This makes the control cabinet more convenient to use, and the entire process of preventing rain, snow, ice and accumulation does not require manual intervention, realizing automated control.

[0025] See Figures 1-4It can be seen that when the rain and snow decrease or stop, the canopy 3 rises under the action of the return spring A503 and the return spring B706. At the same time, the contact block A701 at the bottom of the top plate 705 separates from the contact block B702 and returns to its original state. At this time, the heating wire group 603 stops heating.

[0026] See Figure 3 It is known that guide holes 9 are symmetrically opened on both sides of the top plate 705, and guide rods 8 that pass through the guide holes 9 are symmetrically arranged on both sides inside the box body 704. The top plate 705 and the box body 704 form a sliding structure through the guide rods 8 and guide holes 9, which can play a role in supporting and limiting the top plate 705, thereby increasing the stability of the top plate 705 during the movement process and preventing displacement.

[0027] The working principle of this utility model is as follows: When rain and snow fall to a certain amount, the canopy 3 and the guide plate 502 move vertically downward, causing the return spring A503 to contract under force. At the same time, the top plate 705 moves downward and makes the contact block A701 contact the contact block B702, so that the battery 703, contact block B702, contact block A701 and heating wire assembly 603 form a closed circuit, thereby enabling the heating wire assembly 603 to obtain the required electrical energy and start heating. At the same time, the heat is evenly transferred to the canopy 3 through the heat conduction plate 602 so as to melt the rain and snow on its top, prevent freezing, and allow the rain and snow to slide smoothly off the canopy 3, thus avoiding the accumulation of rain and snow on the top of the control cabinet.
