Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated cabins, and in particular to a high-pressure pressure relief channel for a prefabricated cabin. Background Art

[0002] With the development of the economy, new demands have been made on the efficiency of power construction. In order to further shorten the power construction cycle, the "factory processing and prefabricated construction" model is gradually becoming a trend in power construction, and an important part of it is the prefabricated cabin. The prefabricated cabin is a carrier of power equipment. Its size meets the requirements of road transportation. It can accommodate multiple power equipment inside. After prefabrication processing is completed in the factory, the internal equipment is installed and wired, and then it is transported to the site of use as a whole. The cabin has the ability to control the internal environment and can provide good operating conditions for the internal equipment.

[0003] A high-voltage switch cabinet is generally installed inside the prefabricated cabin. During the operation of the switch cabinet, a short circuit fault may occur in the primary circuit due to various reasons (short circuit, insulation aging, misoperation, etc.). Under the action of tens of thousands of amperes of short-circuit current, high-temperature and high-pressure gas is instantly generated. However, the prefabricated cabin in the prior art does not have a device for monitoring the high-temperature and high-pressure gas. When there is high-temperature and high-pressure gas in the cabinet, the staff cannot be quickly alerted, and the gas cannot be effectively released in a short time in the narrow cabinet, which will cause the switch cabinet to explode and damage the adjacent switch cabinets. At the same time, it may endanger personal safety and increase the occurrence of safety hazards. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and a high-pressure pressure relief channel for a prefabricated cabin is proposed. The controller controls the battery to energize the buzzer, so that the buzzer sounds an alarm to remind the staff of abnormal high temperature in the cabin, and then controls the start of the power motor through the cooperation of the first conductive joint and the third conductive joint to rotate the connecting disk and multiple blades on its outer wall, so that the high-temperature and high-pressure gas in the high-pressure cabinet is quickly discharged to the outside through the pressure relief window, thereby avoiding the safety hazard caused by the continuous increase in temperature and air pressure in the high-pressure cabinet.

By moving the right magnetic block 28 with the first conductive joint 29 upward, when the first conductive joint 29 moves to contact with the second conductive joint 31, the circuits between the first conductive joint 29 and the second conductive joint 31 and the controller 13 are connected, so that the controller 13 controls the battery 12 to energize the buzzer 15, so that the buzzer 15 sounds an alarm to remind the staff that abnormal high temperature occurs in the cabin 1.

[0034] A groove 30 is provided on the right inner wall of the fixed box 14, and a slide plate 33 is slidably connected in the groove 30.

The first conductive joint 29, the second conductive joint 31 and the third conductive joint 32 are all electrically connected to the controller 13.

[0035] When the present invention is used, when the high-voltage cabinet 7 in the cabin 1 has high temperature and high pressure due to the failure of the internal electronic components, the high temperature will cause the low-temperature evaporative liquid 34 in the glass tube 16 to be heated, vaporized and expanded, so that the low-temperature evaporative liquid 34 pushes the movable plate 27 to move between the fixed box 14 and the left side wall of the baffle 35, so that the movable plate 27 moves with the left magnetic block 28 in the left movable groove 26, and under the effect of the opposite attraction between the two magnetic blocks 28, the two magnetic blocks 28 move with the movement of the movable plate 27 at the same time, so that the right magnetic block 28 moves up with the first conductive joint 29, and when the first conductive joint 29 moves to contact with the second conductive joint 31, the circuit between the first conductive joint 29 and the second conductive joint 31 and the controller 13 is connected, so that the controller 13 controls the storage battery 12 to energize the buzzer 15, so that the buzzer 15 sounds an alarm to remind the staff that the cabin 1 has a high temperature abnormality;

[0036] When the temperature in the high-voltage cabinet 7 continues to rise, the magnetic block 28 will continue to move with the first conductive joint 29, and through the cooperation of multiple inclined surfaces between the first conductive joint 29 and the second conductive joint 31, the first conductive joint 29 squeezes the second conductive joint 31 and retracts it into the groove 30. As the first conductive joint 29 continues to move upward, the first conductive joint 29 will contact the third conductive joint 32, so that the circuit between the third conductive joint 32, the first conductive joint 29 and the power motor 17 and the controller 13 is turned on, so that the controller 13 controls the storage battery. The pool 12 supplies power to the power motor 17, so that the power motor 17 starts to drive the rotating shaft 21 to rotate. Under the cooperation of the two bevel gears 25 between the rotating shaft 21 and the rotating rod 22, the rotating rod 22 rotates, so that the rotating rod 22 drives the connecting plate 19 to rotate, so that the multiple blades 20 on the outer wall of the connecting plate 19 rotate to produce a blowing effect, thereby accelerating the circulation speed of the air in the pressure relief channel body 8, so that the high-temperature and high-pressure gas in the high-pressure cabinet 7 is quickly discharged to the outside through the pressure relief window 4, avoiding the safety hazard caused by the continuous increase of temperature and pressure in the high-pressure cabinet 7;

[0037] When the temperature in the high-voltage cabinet 7 drops, the low-temperature evaporative liquid 34 will slowly liquefy, causing the air pressure in the fixed box 14 to decrease, so that the movable plate 27 returns to the starting position with the two magnetic blocks 28. Therefore, the right magnetic block 28 brings the first conductive connector 29 to separate from the second conductive connector 31 and the third conductive connector 32 and return to the starting position, so that the controller 13 controls the battery 12 to stop supplying power to the buzzer 15 and the power motor 17, so that the buzzer 15 and the power motor 17 stop working, while continuing to detect the air pressure and temperature in the high-voltage cabinet 7, bringing convenience to people.
