Referring to fig. 2, the abutting triggering unit 21 includes a flexible abutting block 211 and a first guide plug 212, one end of the flexible abutting block 211 is in abutting sliding fit with the induction door 12, and the other end of the flexible abutting block 211 is fixedly connected with the first guide plug 212; the first guide plug 212 is located at the first opening end 22111 and forms a sealing, embedding, sliding fit with the displacement transmission groove 2211, and the first guide plug 212 forms a contact fit with the displacement transmission liquid 222.

Referring to fig. 2, the barrier protection unit 23 includes a second guide plug 231, a guide rod 232, and a shielding plate 233, and one end of the guide rod 232 is fixedly connected with the shielding plate 233; the protection plate 233 is also provided with a sealing strip to realize sealing and abutting fit with the side wall of the inlet and outlet of the pickling room; the other end of the guide rod 232 is fixedly connected with the second guide plug 231; the second guide plug 231 is located at the second opening end 22112 and forms a sealing, embedding, sliding fit with the displacement transmission groove 2211, and the second guide plug 231 forms a contact fit with the displacement transmission liquid 222.

In actual work, in the process that the ground rail car enters the pickling room, when the induction door 12 moves to the terminal of the opening direction, the induction door 12 presses the flexible abutting block 211 and forms abutting sliding fit with the flexible abutting block 211, and the flexible abutting block 211 moves along the opening direction parallel to the entrance and the exit and presses the displacement transmission liquid 222 through the first guide plug 212. According to the Pascal principle, the pressure applied to the closed liquid is transmitted to every part of the liquid in equal size; therefore, the displacement transmission liquid 222 is pressed by the first guide plug 212, and then the pressure is transmitted to the second guide plug 231, and then the second guide plug 231 pushes the guide rod 232, so that the guide rod 232 moves in a direction parallel to the inlet-outlet opening until the guide rod 232 abuts against the side wall of the inlet-outlet of the pickling door. After the ground rail car completely enters the pickling room, the induction door 12 moves towards the closing direction, the abutting fit with the flexible abutting block 211 is removed, the reverse movement of the protection plate 233 is realized, and the resetting of the sealing mechanism 2 is realized.

The implementation principle of the automatic induction door opener for the pickling room in the embodiment of the application is as follows:

during actual work, the ground rail vehicle enters between the two infrared distance measuring instruments 11, and at the moment, the infrared distance measuring instruments 11 sense the existence of the ground rail vehicle and feed back signals to the controller 13, so that the controller 13 controls the sensing door 12 to be opened; staff's accessible sets up induction door 12 for transparent glass door, observes the condition of ground rail car in the pickling room, treats that the ground rail car gets into the pickling room completely after, and infrared distance meter 11 detects that the ground rail car has driven away from, feeds back the signal to controller 13, makes controller 13 control induction door 12 close. Therefore, the effects that the induction door 12 is automatically opened according to the approach of the ground rail car and the ground rail car is automatically closed after entering the pickling room are achieved, manual opening of the door by workers is not needed, and the workers are protected from acidic smoke in the pickling room.

When the induction door 12 moves to the terminal of opening the direction, the induction door 12 extrudes the flexible abutting block 211, and forms abutting sliding fit with the flexible abutting block 211, the flexible abutting block 211 moves along the opening direction parallel to the entrance and the exit, and the first guide plug 212 extrudes the displacement transmission liquid 222 to push the guide rod 232, so that the guide rod 232 moves along the direction parallel to the opening direction of the entrance and the exit, and the protection plate 233 abuts against the side wall of the entrance and the exit of the pickling room to play a role in sealing.

When the sensing door 12 is not in abutting engagement with the flexible abutting block 211 any more in the process of closing the sensing door 12, the pressure acting on the displacement transmission liquid 222 is also lost, and the protection plate 233 is reset.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
