Description

Technical Field

[0001] This utility model relates to the field of electrical cabinets, specifically to an electrical cabinet with a security structure. Background Technology

[0002] Electrical cabinets typically house various electrical components, such as circuit breakers, contactors, and relays. These devices are valuable and crucial to system operation. Security features protect the electrical cabinets from external damage and unauthorized intrusion, preventing equipment damage and ensuring stable operation.

[0003] The existing technology has the following problems:

[0004] 1. Conventional security structures use thickened steel plates as the shell of the electrical cabinet, which results in the electrical cabinet being too heavy and inconvenient to move;

[0005] 2. Conventional security structures use a closed design. When overheating and internal combustion occur, the heavy shell cannot open and close in time to extinguish the fire and retard flames, resulting in damage to the internal electrical components, which is a deficiency. Utility Model Content

[0006] (I) Purpose of the utility model

[0007] To address the technical problems existing in the background art, this utility model proposes an electrical cabinet with a security structure, featuring a combined shell structure to ensure impact resistance and a flame-retardant mechanism to assist in fire extinguishing and fire prevention within the cabinet.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides an electrical cabinet with a security structure, including an outer cabinet and an inner cabinet fitted inside the outer cabinet. The front surface of the outer cabinet is equipped with an openable and closable cabinet door, and the inner cabinet has a partition plate with a built-in partition cavity.

[0010] The support mechanism includes an inner cabinet frame sleeved on the outside of the inner cabinet and an outer cabinet frame attached to the inner wall of the outer cabinet. Several support rods are provided between the inner cabinet frame and the outer cabinet frame, and spring members connecting the inner cabinet frame and the outer cabinet frame are provided on the side of the support rods.

[0011] The interlayer between the outer cabinet and the inner cabinet is also provided with opposing corrugated plates.

[0012] The flame-retardant mechanism includes a gas tank and a gas concentration monitor located below the partition plate. The gas tank is equipped with a gas valve at the inlet and outlet ends, and the other end of the gas valve is connected to a three-way pipe. The three-way pipe is connected to the interlayer separating the outer cabinet and the inner cabinet through a vent pipe.

[0013] Preferably, both the inner cabinet frame and the outer cabinet frame are U-shaped structures, and the two are combined and arranged in the upper, middle and lower parts of the interlayer between the outer cabinet and the inner cabinet.

[0014] Preferably, the upper and lower parts of the corrugated plate are supported by the inner cabinet frame and the outer cabinet frame, and the gap between the end faces of the two plates attached to the outer cabinet and the inner cabinet is filled with flame-retardant filler.

[0015] Preferably, the gas cylinder is mounted on the bottom of the inner cabinet via a gas cylinder rack, and the gas concentration monitor is signal-connected to the gas valve mounted on the gas cylinder rack.

[0016] Preferably, one end of the vent pipe that passes through the side wall of the inner cabinet is inserted into the gap between the two corrugated plates.

[0018] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0019] 1. When the electrical cabinet is impacted by external forces, the outer cabinet body is the first to be hit by the external force. Subsequently, the inner and outer cabinet frames with the "U" structure and the support rods bear the impact. The impact process is buffered by spring components. Similarly, the corrugated plate has a corrugated structure, which has the function of absorbing impact force and preventing the impact from directly affecting the internal electrical components.

[0020] 2. The oxygen concentration inside the cabinet is monitored by a gas concentration monitor. When the oxygen level exceeds the standard, inert gas is supplied through the cooperation of gas cylinder, three-way pipe and vent pipe to reduce the risk of spontaneous combustion of the electrical cabinet. On the other hand, the inert gas filling the gaps can prevent the internal combustion from being affected when external combustion occurs. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] like Figure 1-3 As shown, the present invention proposes an electrical cabinet with a security structure, including an outer cabinet 11 and an inner cabinet 12 fitted inside the outer cabinet 11. The front surface of the outer cabinet 11 is equipped with an openable and closable cabinet door 14. The end face of the cabinet door 14 that is attached to the opening of the outer cabinet 11 is equipped with a sealing frame to seal the cabinet closure gap. A protruding handle 15 is installed on the outside to assist in opening and closing the cabinet door 14. The inner cabinet 12 has a partition plate 13 with a built-in partition cavity.

[0028] The support mechanism includes an inner cabinet frame 21 sleeved on the outside of the inner cabinet 12 and an outer cabinet frame 22 attached to the inner wall of the outer cabinet 11. Several support rods 23 are provided between the inner cabinet frame 21 and the outer cabinet frame 22. Spring members 24 connecting the inner cabinet frame 21 and the outer cabinet frame 22 are provided on the side of the support rods 23.

[0029] Corrugated panels 3 are also installed in the interlayer between the outer cabinet 11 and the inner cabinet 12.

[0030] It should be noted that both the inner cabinet frame 21 and the outer cabinet frame 22 are "U-shaped" structures. The "U-shaped" structure design can clamp the inner cabinet 12 on the left, right and rear, and also support the outer cabinet 11 on the left, right and rear. The two are combined and set in the upper, middle and lower parts of the interlayer between the outer cabinet 11 and the inner cabinet 12, serving as the skeleton between the inner and outer cabinets.

[0031] In one embodiment, when the electrical cabinet is impacted by external forces, the outer cabinet 11 is impacted first, and then the impact is absorbed by the inner and outer cabinet frames with the "U" structure and the support rod 23. The impact process is buffered by the spring 24. Similarly, the corrugated plate 3 has a corrugated structure, which has the function of absorbing impact force and preventing the impact from directly affecting the internal electrical components.

[0032] To further enhance the flame-retardant performance of the electrical cabinet, the upper and lower parts of the corrugated plate 3 are supported by the inner cabinet frame 21 and the outer cabinet frame 22. The gap between the end faces of the outer cabinet body 11 and the inner cabinet body 12 is filled with flame-retardant filler. The flame-retardant filler has strong heat resistance and can be flame-retardant. At the same time, the flame-retardant filler can also act as an impact-resistant structure for collision protection.

[0033] like Figure 3 As shown, the flame-retardant mechanism includes a gas tank 42 and a gas concentration monitor 46 located below the partition plate 13. The gas tank 42 is equipped with a gas valve 43 at the inlet and outlet ends. The other end of the gas valve 43 is connected to a three-way pipe 44. The three-way pipe 44 is connected to the interlayer separating the outer cabinet 11 and the inner cabinet 12 through a vent pipe 45.

[0034] In one embodiment, the oxygen concentration inside the cabinet is monitored by a gas concentration monitor 46. When the oxygen level exceeds the standard, inert gas is supplied through the cooperation of a gas cylinder 42, a three-way pipe 44, and a vent pipe 45. One end of the vent pipe 45 penetrates the side wall of the inner cabinet 12 and enters the gap between two corrugated plates 3, reducing the risk of spontaneous combustion of the electrical cabinet. On the other hand, the inert gas filling the gap can prevent the interior from being affected by combustion when external combustion occurs.

[0035] To ensure stable installation of the gas cylinder 42, the gas cylinder 42 is further installed at the bottom of the inner cabinet 12 via a gas cylinder rack 41, and the gas concentration monitor 46 is connected to the gas valve 43 installed on the gas cylinder rack 41.

[0036] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
