Through setting up flap door resetting means 4, when drive structure 2 and actuation part 42 all cut off the power supply, actuation part 42 is electromagnetism actuation part 42 in this embodiment, drive structure 2 stop work, the magnetic force between first actuation portion 421 and the second actuation portion 422 disappears, elastic component 43 resets and drives and rotate seat 41 and rotate around door pivot 5, first cylinder 412 rotates and drives second cylinder 44 along with rotating seat 41, door pivot 5 rotates and drives door 1 and rotate along with second cylinder 44, when elastic component 43 resumes natural state, door 1 is in the open mode, thereby realize the outage of flap door and reset, ensure that flap door can effectively form after the outage and open and be in the current state.

In addition, the embodiment further explains the working principle of the flap gate on the basis of the above technical solution, and specifically includes the following processes:

an initialization process: the driving structure 2 and the attraction part 42 are respectively electrified, the driving structure 2 drives the door body rotating shaft 5 to rotate after being electrified, in the rotating process of the door body rotating shaft 5, the first cylinder 412 rotates along with the second cylinder 44, the rotating seat 41 rotates along with the first cylinder 412 around the door body rotating shaft 5, meanwhile, the elastic part 43 is compressed or stretched, when the door body rotating shaft 5 rotates until the first attraction part 421 contacts with the second attraction part 422, the driving structure 2 stops working, the first attraction part 421 attracts the second attraction part 422, the position of the rotating seat 41 is locked by the attraction part 42, the elastic part 43 is in a compression or stretching state and has elastic force for separating the first attraction part 421 from the second attraction part 422, and initialization is completed.

And (3) normal working process: the driving structure 2 and the attraction part 42 are respectively electrified, the first attraction part 421 and the second attraction part 422 are attracted, and the elastic element 43 is in a stretching or compressing state and has an elastic force which enables the first attraction part 421 and the second attraction part 422 to be separated; the driving structure 2 drives the door body rotating shaft 5 to rotate forward and backward so as to open or close the door body 1, the normal work of the flap door is completed, and the flap door is in a closed state at the moment;

a power-off reset process: when the driving structure 2 and the suction part 42 are both powered off, the driving structure 2 stops working, the magnetic force between the first suction part 421 and the second suction part 422 disappears, the elastic part 43 resets and drives the rotating seat 41 to rotate around the door body rotating shaft 5, the first cylinder 412 rotates along with the rotating seat 41 and drives the second cylinder 44 to rotate, the door body rotating shaft 5 rotates along with the second cylinder 44 and drives the door body 1 to rotate, when the elastic part 43 recovers to a natural state, the door body 1 is in an open state, and the flapping door is in a passing state at the moment.

Referring to fig. 6-9, to better explain the present embodiment, a specific example of the method for controlling the flap door will be described below, in which when the flap door is not powered on, the tension spring is in a natural state, and when the flap door is installed, the flap door is manually adjusted, so that the door body 1 is in an open state in the direction away from the station at this time, and thus, when the flap door is not in a working state, a person can smoothly pass through the flap door, and at this time, if the flap door needs to be changed in position, the elastic force of the tension spring needs to be overcome, so that when the flap door is not powered on, the door body 1 is in an open state in the direction away from the station. After the clap door is powered on, the driving structure 2 is initialized firstly, so that the clap door reset device 4 is in a ready-to-operate state, wherein the initialization process is that the driving structure 2 drives the door body 1 to rotate towards the entering direction, namely, the door body 1 rotates from the position shown in fig. 6 to the position shown in fig. 7, in the initialization process, the door body rotating shaft 5 rotates, simultaneously, the second column 44 on the door body rotating shaft 5 rotates synchronously along with the door body rotating shaft 5, in the rotating process of the second column 44, the first column 412 is driven to rotate due to contact with the first column 412, because the first column 412 is fixed on the rotating base 41, the rotating base 41 rotates along with the first column 412, when the door body 1 rotates to the position shown in fig. 7, the first suction part 421 contacts with the second suction part 422, because the electromagnet 4212 of the first suction part 421 is powered on and generates a magnetic field around the first suction part 421, when the first suction part 421 contacts with the second suction part 422, the electromagnet 4212 of the first suction portion 421 sucks the magnetic body 4221 of the second suction portion 422, the position of the rotating seat 41 is locked by the suction member 42, and simultaneously the tension spring is stretched and has an elastic force to separate the first suction portion 421 from the second suction portion 422, and the initialization is completed.

When the driving structure 2 and the suction part 42 are both powered off, the driving structure 2 stops working, the magnetic force between the first suction part 421 and the second suction part 422 disappears, the tension spring resets and drives the rotating seat 41 to rotate around the door body rotating shaft 5, the first cylinder 412 rotates along with the rotating seat 41 and drives the second cylinder 44 to rotate, the door body rotating shaft 5 rotates along with the second cylinder 44 and drives the door body 1 to rotate, when the tension spring restores to a natural state, the door body 1 is in an open state, thereby realizing the power-off reset of the flap door, ensuring that the flap door can effectively form an open passing state after the power-off, and even ensuring that the flap door restores to the state without power-on.

In addition, according to the flap door control method provided by the technical scheme, when the flap door normally works, the first suction portion 421 and the second suction portion 422 are sucked, the tension spring does not rotate along with the driving structure 2 and is always in a stretching or compressing state, and the tension force of the tension spring does not need to be overcome when the door body 1 rotates, so that the load of a motor of a core of the flap door is reduced, and the service life and the stability of the motor of the core of the flap door are improved. In addition, when the flap door normally works, the first suction portion 421 and the second suction portion 422 are sucked, the position of the rotating seat 41 is locked by the suction part 42, and the tension spring does not rotate along with the driving structure 2 and is always in a stretching state, so that fatigue fracture caused by long-term repeated deformation of the tension spring is avoided, the maintenance cost of personnel is reduced, and the safety and reliability of the flap door are improved.
