DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0027] See also Figure 1-4 In the utility model, an electrical equipment integrated control cabinet comprises an outer control cabinet 1 and an inner control cabinet 2, a sliding mounting seat 3 is fixedly mounted on the inner bottom wall of the outer control cabinet 1, and the inner control cabinet 2 is mounted on the sliding mounting seat 3;

[0028] The control inner cabinet 2 includes evenly distributed vertical plates 21, and the top and bottom between the vertical plates 21 are fixedly connected with a top plate 22 and a bottom plate 23 respectively. An inner cabinet door 24 is hinged between the top plate 22 and the bottom plate 23, and the inner cabinet door 24 is located on the front of the vertical plates 21. Rubber tubes 25 that cooperate with each other are fixedly installed between two adjacent vertical plates 21. A compressed gas cylinder 26 is fixedly installed on the top plate 22, and a connecting pipe 27 is fixedly installed at the bottle mouth of the compressed gas cylinder 26. The other end of the connecting pipe 27 passes through the top plate 22 and is fixedly connected to the rubber tube 25, and the connecting pipe 27 is connected to the inside of the rubber tube 25. A solenoid valve 28 is fixedly installed on the connecting pipe 27. A smoke sensor 29 is fixedly installed inside the control inner cabinet 2, and the output end of the smoke sensor 29 is electrically connected to the solenoid valve 28.

[0029] In the utility model, a double-layer structure of an outer control cabinet 1 and an inner control cabinet 2 is provided, wherein the inner control cabinet 2 is used to install electrical equipment of the control cabinet, and the outer control cabinet 1 is used as an outer protective structure to play an anti-collision protection role. In a normal state of the integrated control cabinet, the rubber tube 25 is in a contracted state, so there is a gap between two adjacent vertical plates 21. Once a cable burns inside the control cabinet, smoke will be generated. The smoke sensor 29 is used to detect the internal smoke. When the smoke is detected, it is determined that a high-temperature combustion state occurs inside the inner control cabinet 2. The control solenoid valve 28 is opened, and the high-pressure gas in the compressed gas cylinder 26 is introduced into the rubber tube 25 by the connecting pipe 27, so that the rubber tube 25 expands. The two adjacent rubber tubes 25 cooperate with each other to seal the gap between the two vertical plates 21. If the inner side of the rubber tube 25 is burned and damaged, nitrogen is filled into the inner control cabinet 2 to further dilute the oxygen to achieve a fire extinguishing state, thereby improving the safety of the control cabinet.

[0030] See also Figure 1, wherein: a heat dissipation fan 11 is fixedly installed inside the control outer cabinet 1, and heat dissipation holes 12 are opened on both sides of the control outer cabinet 1.

[0031] In the utility model, the heat dissipation fan 11 installed on the outer cabinet 1 is controlled to increase the air flow, and the air is exchanged with the outside through the heat dissipation holes 12, thereby improving the heat dissipation effect of the heat dissipation cabinet.

[0032] See also Figure 1 , wherein: the sliding mounting seat 3 includes a fixed seat 31 , two sliding guide rails 32 are fixedly mounted on the top of the fixed seat 31 , and the bottom plate 23 is slidably mounted between the two sliding guide rails 32 .

[0033] In the utility model, the sliding connection between the sliding guide rail 32 on the fixed seat 31 and the bottom plate 23 enables the control cabinet 2 to be slid out when the electrical equipment inside the control cabinet is inspected and repaired, which is convenient for inspecting the electrical equipment and more convenient for operation.

[0034] See also Figure 1 , wherein: the initial state of the rubber tube 25 is a flat state, and the interior of the rubber tube 25 is in a negative pressure state.

[0035] In the utility model, when the rubber tube 25 is in a negative pressure flat state, the rubber tube 25 is in close contact with the vertical plate 21 as a whole, which reduces the occupation of the gap between two adjacent vertical plates 21 by the rubber tube 25 and facilitates air circulation and heat dissipation.

[0036] See also Figure 2 , wherein: the cross-sectional shapes of the two adjacent rubber tubes 25 are convex and concave respectively, and the internal high-pressure gas of the compressed gas cylinder 26 is nitrogen.

[0037] In the utility model, two adjacent rubber tubes 25 of the convex shape and the concave shape can fit each other in the expanded state, thereby improving the sealing effect. Nitrogen is an inactive gas, and if leakage occurs, the danger is relatively low.

[0038] See also Figure 1 , wherein: an equipment mounting frame 4 for mounting electrical equipment is fixedly mounted on the bottom plate 23 .

[0039] In the utility model, the electrical equipment is conveniently and adaptably installed through the equipment mounting frame 4, thereby enriching the functions of the control cabinet.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
