Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an electrical cabinet with an independent instrument room, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented by the following technical scheme: an electrical cabinet with an independent instrument room, comprising an equipment frame, a detector is fixedly installed on the top of the inner wall of the equipment frame, a servo motor is fixedly installed on the top of the inner wall of the equipment frame, and an exhaust device; wherein the exhaust device comprises a rotating rod, a connecting plate, a frame, a supporting rod, a fan, a screw rod, a sliding block, a baffle and a long plate, the rotating rod is fixedly installed on the output end of the servo motor, the connecting plate is slidably installed inside the equipment frame, an exhaust port is opened on the surface of the equipment frame, the frame is fixedly installed inside the exhaust port, the supporting rod is fixedly installed inside the frame, the fan is fixedly installed on one end of the supporting rod away from the frame, the screw rod is fixedly installed on one end of the fan away from the connecting plate, the sliding block is slidably installed on the circumferential surface of the screw rod, the baffle is fixedly installed on one end of the sliding block away from the screw rod, and the long plate is fixedly installed above the frame, the fan is started, the fan drives the screw rod to rotate, the screw rod rotates to drive the sliding block to move to the side away from the fan, the sliding block moves and drives the baffle to move, so that the baffle releases the closure of the frame.

The movement of the sliding block 10 drives the baffle 11 to move, so that the baffle 11 releases the closure of the frame 6, thereby realizing ventilation between the inside of the cabinet and the outside, and preventing the items stored in the cabinet from being damp due to long-term lack of ventilation, thereby causing the items to be damaged.

[0021] A threaded groove is provided on the surface of the rotating rod 4, the connecting plate 5 is connected to the rotating rod 4 by threads, the baffle 11 is fixedly connected to the bottom of the long plate 12, the interior of the detector 2 is provided with a sensing module and a control module, the control module is electrically connected to the servo motor 3, the connecting plate 5 moves up and down through the threaded groove on the circumferential surface of the rotating rod 4, and moves the long plate 12 toward the side close to the fan 8 by pushing the long plate 12, and at the same time the baffle 11 moves toward the side close to the fan 8 through the long plate 12, thereby resetting and reclosing the frame 6.

[0022] When the present embodiment is working: when ventilation is needed, the fan 8 is started, the fan 8 drives the screw rod 9 to rotate, the screw rod 9 rotates and drives the sliding block 10 to move to the side away from the fan 8, the sliding block 10 moves and drives the baffle 11 to move, so that the baffle 11 releases the closure of the frame 6; when the fan 8 stops rotating and needs to be reset, the long plate 12 is pushed to move to the side close to the fan 8, and the baffle 11 moves to the side close to the fan 8 through the long plate 12, thereby resetting and reclosing the frame 6, realizing ventilation between the inside of the cabinet and the outside world, preventing the items stored in the cabinet from becoming damp due to long-term lack of ventilation, causing the items to be damaged; when the servo motor 3 is started, the output end of the servo motor 3 rotates and drives the rotating rod 4 to rotate, and the connecting plate 5 moves up and down through the threaded groove on the circumferential surface of the rotating rod 4, which facilitates the inspection and maintenance of one side and realizes that the height can be adjusted when one side is damaged without hindering the use of the other part.

At the same time, the connecting plate 5 moves upward to drive the fixed plate 133 to move upward, so that the fixed plate 133 closes the upper half of the exhaust port 101. At this time, the upper part of the connecting plate 5 is completely closed, so that the upper part does not contact the lower part, preventing the overall damage of the equipment and increasing the subsequent maintenance cost. At the same time, when the fixed plate 133 moves upward, the opening below the exhaust port 101 is enlarged, so that the air below can circulate faster, thereby increasing the exhaust efficiency.

[0030] When the receiving frame 131 moves downward, it drives the gas tank 141 downward, the gas tank 141 moves downward, drives the sleeve 142 downward, drives the sleeve 142 downward, drives the cylinder 143 downward, drives the fixing block 144 downward, the downward moving chamfer of the fixing block 144 contacts and squeezes the convex surface of the arc block 147, and makes the fixing block 144 move to the side close to the gas tank 141, and the movement of the fixing block 144 drives the cylinder 143 to move, thereby releasing the connection block 145 is limited, when the receiving frame 131 continues to move downward, it drives the connecting block 145 to move downward, and the connecting block 145 moves downward, drives the bevel block 146 to move downward to contact the extrusion arc block 147, and makes the bevel block 146 rotate to drive the connecting block 145 to rotate, thereby opening the carbon dioxide inside the gas tank 141 and releasing it above the connecting plate 5 to extinguish the fire, prevent the fire from spreading, and prevent accidents. At the same time, the limit can prevent the carbon dioxide inside the gas tank 141 from being accidentally opened during movement, resulting in waste.
