[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides the following technical solutions: an access control gate with a line protection structure comprises a device housing 1, a support column 2 is fixedly connected to the upper surface of the device housing 1, and an identifier 3 is fixedly connected to the outer surface of the support column 2;

[0026] A fuse 4 is fixedly connected to the inner surface of the device housing 1, and a signal line 5 is fixedly connected to the output contact of the fuse 4;

[0027] The other end of the signal line 1 5 is fixedly connected to the air switch 6, and the output contact of the air switch 6 is fixedly connected to the signal line 5 22;

[0028] The other end of the signal line 5 22 is fixedly connected to a thermal relay 9, the normally open contact of the thermal relay 9 is fixedly connected to the signal line 2 7, and the other end of the signal line 2 7 is fixedly connected to an alarm 8;

[0029] The output end of the thermal relay 9 is fixedly connected to a signal line 3 10, the other end of the signal line 3 10 is fixedly connected to a motor 11, and the output end of the motor 11 is fixedly connected to a first gear 12;

[0030] A temperature sensor 13 is fixedly connected to the inner surface of the device housing 1 , and a detection needle 14 is fixedly connected to the outer surface of the temperature sensor 13 .

[0031] In this embodiment, by connecting the main components in series, any part of the equipment can be stopped if an abnormality is detected, thereby avoiding damage to the equipment. By setting the gas discharge tube 15, the equipment has the ability to withstand lightning strikes, thereby avoiding damage to the equipment caused by instantaneous overload caused by lightning strikes. By setting the thermal relay 9, the thermal relay 9 can disconnect the line connection in time when the equipment is overheated. By setting the circuit breaker, the equipment can trip in time when a short circuit occurs, thereby avoiding damage to the equipment caused by excessive current. By setting the fuse 4, the equipment line has multiple protections. By setting the temperature sensor 13, the temperature inside the equipment can be monitored. By setting the detection needle 14, the temperature detected by the temperature sensor 13 is more accurate and more sensitive. By setting the signal line four 16, the detonating block 17 can receive the current output by the temperature sensor 13 in time and blast the high-pressure gas tank 18 in time.

[0032] Specifically, the outer surface of the temperature sensor 13 is fixedly connected with a signal line 16, and the other end of the signal line 16 is fixedly connected with a detonating block 17. Through the setting of the detonating block 17, the high-pressure gas tank 18 can be ruptured in time.

[0033] Specifically, a fixing ring 19 is fixedly connected to the inner surface of the equipment housing 1, a high-pressure gas tank 18 is sleeved on the inner surface of the fixing ring 19, a detonating block 17 is clamped on the top of the high-pressure gas tank 18, and pre-fracture marks are provided on the inner and outer surfaces of the high-pressure gas tank 18. By providing the pre-fracture marks, the rupture of the high-pressure gas tank 18 is predictable, and the force required for blasting is smaller.

[0034] Specifically, the internal rotation of the device housing 1 is connected to the second gear 21, the second gear 21 is meshed with the first gear 12, the internal rotation of the device housing 1 is connected to the access control plate 23, and the internal rotation of the device housing 1 is connected to the closing plate 20. By meshing the first gear 12 with the second gear 21, the release action of the access control plate 23 is faster.

[0035] Specifically, the gas discharge tube 15 is fixedly connected to the output contact of the fuse 4 in a parallel state. Through the parallel setting, the gas discharge tube 15 can exert its own characteristics.

[0036] Specifically, the fuse 4, the air switch 6, the thermal relay 9 and the motor 11 are connected in series, and are arranged in series so that all the connections can be disconnected by disconnecting any one of them.

[0037] Specifically, the number of the detection needles 14 is six and they are symmetrically arranged. By arranging a plurality of detection needles 14 , the temperature sensor 13 can detect the temperature more sensitively and accurately.

[0038] The working principle or use process of the utility model is as follows: first, the device can perform face recognition on the identifier 3 or swipe the card to square the device. After the face operation, the motor 11 will drive the first gear 12 to rotate, and the second gear 21 will drive the access control plate 23 to release. If a short circuit or other conditions that cause the device to heat up occur, first the thermal relay 9 will disconnect the short circuit, and the normally open contact will close, so that the alarm 8 is connected to the power supply to produce an alarm sound. If the line overheats, the fuse inside the fuse 4 will melt, and the air switch will be disconnected, so that the device is in a power-off state. If combustion occurs inside the device, the temperature sensor 13 will transmit current to the detonating block 17, and the detonating block 17 will cause the high-pressure gas tank 18 to explode, so that the carbon dioxide gas inside it fills the inside of the device. If a lightning strike occurs, the gas discharge tube 15, due to its special internal structure, protects the device from lightning damage and avoids damage to the internal parts of the device. When the utility model is in use, the electrical equipment in this device is all externally powered and controlled to run and shut down by a matching control switch.

[0039] Finally, it should be noted that the above is only the preferred embodiment of the utility model, and is not intended to limit the utility model. This specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the utility model, so that technicians in the relevant technical field can well understand and use the utility model.
