Description

Technical Field

[0001] The utility model relates to the technical field of control cabinets, in particular to a control cabinet with an isolation structure. Background Art

[0002] The electrical control cabinet is a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment. It is widely used in automatic fire electrical control.

[0003] An existing patent (authorization announcement number: CN 219477275 U) discloses a control cabinet with an isolation structure, which is conducive to isolating the fire inside the control cabinet body to a certain extent by setting an isolation mechanism, thereby extending the fire-fighting time for employees, and preventing the fire inside the control cabinet body from spreading to the adjacent control cabinet body and causing greater losses. First, the screw rod is rotated by turning the handle. When the screw rod is rotated, the two groups of fireproof isolation plates 2 move out from the fireproof isolation plate 1 and gradually approach as the screw rod rotates. There is a certain overlap between the surfaces of the two groups of fireproof isolation plates 2 and the fireproof isolation plate 1, which can play a certain barrier role on the fire inside the control cabinet body. By setting a fire-blocking pad, fire can be prevented from spraying out through the gap between the two groups of fireproof isolation plates.

[0004] However, the above technical solution still has certain defects. The isolation structure is located on both sides of the front surface of the control cabinet body, which makes the front surface space of the control cabinet body narrow, resulting in obstacles for manual disassembly and assembly of components in the control cabinet. At the same time, when a fire occurs in the control cabinet body, the temperature around it is relatively high, and manual rotation of the turntable is required to complete the isolation purpose. There is a certain risk factor. Therefore, a control cabinet with an isolation structure is proposed. Utility Model Content

[0027] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] A control cabinet with an isolation structure, such as Figures 1 to 7 As shown, it includes a control cabinet body 100, a cabinet door 110 is rotatably connected to the front surface of the control cabinet body 100, an isolation component 200 is installed on the top of the inner wall of the control cabinet body 100, and a pair of fire extinguishing tanks 300 extending into the control cabinet body 100 are installed on the rear surface of the control cabinet body 100;

[0030] The isolation assembly 200 includes a storage frame 201 fixed to the inner wall of the top of the control cabinet body 100, and a reel 203 is provided in the storage frame 201 to be rotatably connected to the left and right inner walls of the control cabinet body 100. The outer wall of the reel 203 is wrapped with a flame retardant cloth 202 extending to the outside of the bottom end of the heat conducting plate 210, and a weighting strip 204 is fixed to the end of the flame retardant cloth 202. A heat conducting plate 210 is provided in the control cabinet body 100 on one side of the storage frame 201, and the top of the heat conducting plate 210 is near the corner. A telescopic rod 212 is fixed at the position, and the top of the telescopic rod 212 is fixed to the inner wall of the top of the control cabinet body 100. The bottom end of the storage frame 201 is located on the side of the weighted strip 204 close to the heat conducting plate 210 and a guide frame 205 is fixed thereon. A locking rod 206 is horizontally penetrated in the guide frame 205. One end of the locking rod 206 is in contact with the heat conducting plate 210, and the other end of the locking rod 206 extends into the weighted strip 204. A blind hole 207 is provided at the contact position between the weighted strip 204 and the locking rod 206.

[0031] When smoke and open flames are generated in the control cabinet body 100, the heat conducting plate 210 absorbs heat and transfers it to the glass tube 211, and the glass tube 211 is broken. The heat conducting plate 210 rises under the action of the telescopic rod 212 and no longer interferes with the end of the locking rod 206. At this time, the locking rod 206 moves horizontally to release the limit on the weighting strip 204. The weighting strip 204 is vertically lowered by its own weight, and drives the flame retardant cloth 202 to extend out of the storage frame, forming a barrier on the front surface of the control cabinet body 100, preventing the fire from spreading to the outside and continuing to burn, protecting the surrounding property and the lives and health of people;

[0032] When the heat conducting plate 210 rises and contacts the solenoid valve 330, it is controlled to open, so that the dry powder in the fire extinguisher tank 300 flows through the output pipe 310 and is discharged through the nozzle 320, suppressing and extinguishing the open fire in the control cabinet body 100, providing time for the surrounding personnel to evacuate, and facilitating the arrival of firefighters for fire fighting and rescue.

[0033] Please refer to Figures 1 to 4 One end of the reel shaft 203 extends to the control cabinet body 100 and is fixed with a turntable. A channel is opened at the contact position between the control cabinet body 100 and the turntable, and the channel is connected to the outer wall of the turntable through a bearing.

[0034] Rotating the turntable can drive the reeling shaft 203 to rotate synchronously, so that the extended flame retardant cloth 202 can be reeled in, making subsequent work after the fire more convenient.

[0035] Please refer to Figure 3 and Figure 6 A glass tube 211 in contact with the inner wall of the top of the control cabinet body 100 is provided at the top center of the heat conducting plate 210, and a liquid that is easily expanded by heat is provided in the glass tube 211;

[0036] The fire extinguisher tank 300 is bundled on the rear surface of the control cabinet body 100. The top of the fire extinguisher tank 300 is provided with an output pipe 310 extending into the top of the control cabinet body 100. The end of the output pipe 310 is connected to a solenoid valve 330. The output end of the solenoid valve 330 is connected to a nozzle 320. The bottom end of the solenoid valve 330 is provided with a switch button.

[0037] Liquids that expand easily when heated (such as carbonic acid liquids) absorb heat and expand to crush the glass tube 211 from the inside. The four sets of telescopic rods 212 pull the heat conducting plate 210 upward and contact the switch button provided at the bottom of the solenoid valve 330, so that the solenoid valve 330 is opened, allowing the dry powder inside the fire extinguisher tank 300 to flow through the output pipe 310 and be sprayed out through the nozzle 320, thereby extinguishing the fire in the control cabinet body 100.

[0038] Please refer to Figure 4 , Figure 5 and Figure 6 A circular notch is provided at the contact position between the heat conducting plate 210 and the nozzle 320 , and the diameter of the notch is larger than the nozzle 320 and smaller than the solenoid valve 330 .

[0039] The circular notch hole nozzle 320 can normally spray dry powder to extinguish the fire, which can make the heat conducting plate 210 rise and contact with the solenoid valve 330, thereby controlling the opening thereof.

[0040] Please refer to Figure 7 A return spring is sleeved on the outer wall of the locking rod 206 in the guide frame 205 , and two ends of the return spring are respectively fixed to the outer wall of the locking rod 206 and the inner wall of the guide frame 205 .

[0041] When the heat conducting plate 210 is raised and no longer constrains one end of the locking rod 206 , the return spring releases pressure and causes the locking rod 206 to move laterally, separating it from the weighted strip 204 .

[0042] Please refer to Figure 2 and Figure 5 A strip groove is provided at the bottom of the storage frame 201 where it contacts the flame-retardant cloth 202 , and rolling balls extending into the control cabinet body 100 are provided at both ends of the weighted strip 204 , and a restraining groove is provided at the contact position between the inner wall of the control cabinet body 100 and the rolling ball.

[0043] The strip groove provides space for the flame retardant cloth 202 to extend out of the storage frame 201, ensuring that the flame retardant cloth 202 can be smoothly extended; and the ball and the constraint groove are used to limit the lowering of the weighted strip 204, ensuring that it is lowered in a straight line along a preset trajectory until the purpose of blocking is achieved. At the same time, the ball is used to reduce the resistance of the weighted strip 204 when it is lowered.

[0044] During use, when smoke and open flames are generated in the control cabinet body 100, the heat conducting plate 210 absorbs heat and transfers it to the glass tube 211, and the glass tube 211 is broken. The heat conducting plate 210 rises under the action of the telescopic rod 212 and no longer interferes with the end of the locking rod 206. At this time, the locking rod 206 moves horizontally to release the limit on the weighting strip 204. The weighting strip 204 is vertically lowered by its own weight, and drives the flame retardant cloth 202 to extend out of the storage frame together, forming a barrier on the front surface of the control cabinet body 100, preventing the fire from spreading to the outside and continuing to burn, protecting the surrounding property and the lives and health of people;

[0045] When the heat conducting plate 210 rises and contacts the solenoid valve 330, it is controlled to open, so that the dry powder in the fire extinguisher tank 300 flows through the output pipe 310 and is discharged through the nozzle 320, thereby suppressing and extinguishing the open fire in the control cabinet body 100, providing time for the surrounding personnel to evacuate, and facilitating the arrival of firefighters for fire fighting and rescue. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

[0046] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
