Description

Technical Field

[0002] The gate is a channel blocking device (channel management equipment), which is mainly used in urban rail transit management and toll gate systems to manage the flow of people and regulate the entry and exit of pedestrians. The most typical application of full-height gates is in detention centers, detention centers, custody and education centers, compulsory isolation drug rehabilitation centers, drug rehabilitation centers and other prisons, which are heavily guarded and have full-height gates installed at each channel entrance and exit;

[0003] The gate is mainly composed of fingerprint lock, electromagnetic lock, guardrail, revolving door and photoelectric sensor. Inputting fingerprint or face recognition can make the electromagnetic lock open the revolving door. After the person passes through, the photoelectric sensor is triggered by the person's body blocking, and the electromagnetic lock is closed again. The closing of the revolving door mainly depends on the photoelectric sensor. As an electronic component, the photoelectric sensor is damaged and insensitive. If the revolving door cannot be closed, it is easy for people to escape. In addition, once someone breaks into the revolving door, the person cannot be suppressed and chaos is likely to occur. Therefore, it is necessary to propose a special channel gate for prisons. Summary of the invention

A method for using a gate for a prison passage, which is applied to the gate for a prison passage as claimed in claim 6, characterized in that: The following steps are involved: Step 1: By inputting the fingerprint or face recognition of the person recorded in advance through the fingerprint lock (3), the controller (6) can control the first electromagnet (852) to be energized, and the first electromagnet (852) generates a magnetic field to attract the first insertion rod (854) to move left, so that the first insertion rod (854) moves out of the positioning groove (83), releases the positioning of the turntable (82), rotates the rotating frame (7), and realizes the entry and exit of the person. During the rotation of the turntable (82), the protrusion (84) squeezes the roller, prompting the push rod (865) to move right. , the second squeezing block (866) squeezes the first squeezing block (864) to move upward, the two first contacts (867) are disconnected, the controller (6) receives feedback, the controller (6) turns off the power to the first electromagnet (852), and the first insertion rod (854) is pushed to move rightward under the elastic force of the first spring (853), and after the rotating frame (7) rotates 90 degrees, the first insertion rod (854) is inserted into another positioning groove (83), and the turntable (82) is braked again, so that the rotating frame (7) can only allow one person to enter and exit at a time; Step 2: When a person breaks into the rotating frame (7), the controller (6) energizes the second electromagnet (104) and the electromagnetic valve (912), the electromagnetic valve (912) allows the catheter (95) to be turned on, the second electromagnet (104) generates a magnetic field, the second electromagnet (104) attracts the second plug rod (105) to move upward, the second plug rod (105) moves out of the socket (911), the positioning of the swing rod (910) is released, the gear (98) is driven to rotate clockwise under the torque of the torsion spring (99), the piston (92) moves outward under the transmission of the gear (98) and the rack (94), the tear gas solution (93) is pushed out of the tear gas box (91), and the nozzle (96) sprays the tear gas solution in atomized form to induce tears to the person who breaks in; Step three: the second plug rod (105) acts as a conductor, and the two second contacts (103) form a passage to supply power to the rotating frame (7). An intruder will be electrocuted, thereby preventing the intruder from escaping.
