In the past, alarm devices, such as smoke alarms, were not easy to quickly capture smoke at the beginning of a fire when the flames had not yet increased and only part of the smoke was produced. The distance and time difference between the smoke and the alarm caused the alarm to be unable to detect the fire in a timely and effective manner, delaying the best time to extinguish the fire.

[0010] In the above technical solution, preferably, the plurality of groups of sleeves are evenly distributed in a circular shape, and the slide bar and the sleeve are slidably arranged.

[0011] In the above technical solution, the fan cover is communicated with the interior of the mounting tube, the smoke alarm and the drive motor are wirelessly connected to the external computer terminal, and the fan head is fixedly connected to the base.

[0012] A substation alarm method is also provided, which is used to operate an alarm device for a substation, comprising the following steps: S1: Through the use of the drive motor and the fan head, the air in the substation is drawn into the fan cover to accelerate the internal air flow. The smoke alarm is used to detect the incoming air flow in time to see if there is smoke. S2: After smoke is detected, the rotation of the fan head is accelerated, so that several groups of counterweight blocks move the moving rod outward under the action of centrifugal force, pulling the reset spring. After the several groups of moving rods are deployed, the rotating diameter of the trigger triangle head becomes larger, and it will hit the trigger rod to achieve the purpose of triggering; S3: Through the clockwise rotation of the trigger rod and the rotating disk, the pull ring on one side of the rotating part drives it to rotate to one side. The rotating part is pulled by the double-hook spring to lift the valve plug, and the through hole is connected to the inside of the nozzle. At this time, the dry powder inside the fire extinguisher is pushed out to extinguish the fire in time.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The fan head is driven by a driving motor to run at a normal speed, and the air in the box-type substation is extracted through the fan cover to accelerate the air flow inside the box. The smoke alarm is used to detect the incoming airflow. If smoke is detected, the smoke alarm can provide timely feedback to the computer and issue a prompt alarm sound to remind the surrounding personnel, and control the driving motor to drive the fan head to rotate at a high speed, and the centrifugal force of the rotation drives the trigger component to change.

[0014] Driven by the high-speed rotation of the fan head, several groups of counterweights and trigger triangle heads are thrown outward under the action of centrifugal force, and the moving rod moves outward, pulling the reset spring at the same time. After several groups of moving rods drive the trigger triangle heads to expand, the diameter of the rotation trajectory of several groups of trigger triangle heads becomes larger, and the trigger triangle heads will hit the trigger rod when rotating, thereby triggering the fire extinguishing component, automatically opening the fan cover in time, and effectively handling the disaster.

[0015] After being hit, the trigger rod will rotate clockwise and push the rotating disk to rotate. The rotation of the rotating disk will pull the pull ring, which will push upward with the double-hook spring, so that the rotating part is pulled and rotated by the double-hook spring, and the movable shaft connected on one side and the valve plug on the upper side are pushed upward, so that the through hole is connected to the inside of the nozzle. At this time, the pressure inside the fire extinguisher bottle will push the dry powder inside the bottle to the nozzle and spray it out quickly. In the early stage of the fire, the burning area is small and the fire is weak. Timely control of the fire can prevent the fire from spreading, thereby reducing property losses caused by the fire.

[0016] After the rotating disk rotates, the trigger rod rotates and retracts into the opening. When the rotating disk rotates, the telescopic head is pressed down by the triangular groove to move downward in the fixed sleeve, and the telescopic spring is compressed at the same time. The lower side of the telescopic head will move to the trajectory of the rotating trigger triangle head. After the trigger rod is triggered, the fan head drives the trigger triangle head to rotate at a low speed to hit the telescopic head, so that the two sets of connecting rods rotate along the two sets of connecting sleeves, and at the same time, the two sets of torsion springs are pressed and twisted. The thrust, and several groups of trigger triangle heads hit the telescopic head one by one, and under the action of the two sets of torsion springs, the nozzle rotates along the two sets of connecting sleeves, and the dry powder is swung in the swinging mouth to spray, ensuring that the dry powder can be evenly distributed during spraying, so as to control the fire more effectively and better. At the same time, when the initial flame position is not aligned, it can also be sprayed to extinguish it by swinging. BRIEF DESCRIPTION OF THE DRAWINGS
