Description

Technical Field

[0002] Plasma flame, also known as plasma flame torch, is a high-temperature flame generated by plasma technology. Plasma flame is a phenomenon in which gas or liquid is excited into a plasma state by passing it through an electric field or high-temperature plasma to generate a high-temperature flame. Flame detection devices based on plasma circuits use plasma technology to sense the presence of flames and accurately detect flames by detecting the plasma circuits generated by flames. This technology has the advantages of high sensitivity, rapid response, and high accuracy. It is suitable for various occasions where flames need to be monitored and detected to improve fire warning and safety.

[0003] When detecting the torch flame, the device includes a flame detector for sensing the presence and intensity of the flame. The flame detector may be a photoelectric sensor, an infrared sensor, etc. Dust may affect the normal operation of the infrared sensor during use.

In addition, the flame temperature generated by the plasma torch is relatively high during use. If the distance is too close, there is a risk of burns from the flame.

[0026] In this embodiment, a plasma generator 11 is disposed on the inner wall of the main body 1 , and a gas delivery pipe 12 is disposed on one side of the outer surface of the main body 1 .

[0027] When in use, the gas pipe 12 delivers oxygen or nitrogen required for flame generation to the interior of the main body 1. When the gas passes through the plasma generator 11, it is excited into a plasma state to form a plasma circuit. The plasma state gas has high temperature and high energy characteristics, forming a high temperature flame.

[0028] In this embodiment, a limiting groove 13 is provided on one side of the outer surface of the main body 1, an engaging plate 14 is fixedly connected to one side of the outer surface of the baffle 3, a mounting frame 15 is fixedly connected to one side of the outer surface of the main body 1, a rotating shaft 16 is rotatably connected to the inner surface of the mounting frame 15, a gear 17 is fixedly connected to one side of the outer surface of the rotating shaft 16, the gear 17 is meshingly connected to the engaging plate 14, and the meshing plate 14 is slidably connected to the limiting groove 13.

[0030] In this embodiment, one end of the rotating shaft 16 passes through the inner surface of the mounting frame 15 and extends to the front surface of the mounting frame 15 , and one end of the rotating shaft 16 is fixedly connected to a worm gear 18 .

[0031] During specific use, the worm gear 18 can drive the rotation of the shaft 16 when it rotates, and the shaft 16 can drive the gear 17 to rotate.

[0032] In this embodiment, a worm 19 is rotatably connected to the inner surface of the mounting bracket 15 , and the worm 19 is meshingly connected to the worm wheel 18 .

[0033] During specific use, the worm 19 can mesh with the worm wheel 18 when rotating, thereby driving the worm wheel 18 to rotate.

[0034] In this embodiment, one end of the worm 19 passes through the inner surface of the mounting frame 15 and extends to the side surface of the mounting frame 15 , and one end of the worm 19 is fixedly connected to the thumbwheel 20 .

[0038] Working principle: During use, the gas pipe 12 transports the oxygen or nitrogen required for flame generation to the inside of the main body 1. When the gas passes through the plasma generator 11, it is excited into a plasma state to form a plasma circuit. The gas in the plasma state has the characteristics of high temperature and high energy, forming a high-temperature flame. When the main body 1 generates a plasma flame, the infrared sensor 6 can detect the temperature and intensity of the flame. When dust is deposited on the surface of the infrared sensor 6, the drive motor 10 runs its output end to drive the movable frame 7 to move repeatedly, so that the movable frame 7 uses the sponge brush 8 to wipe the dust on the surface of the infrared sensor 6 to prevent dust from accumulating on the infrared sensor 6 and blocking the infrared sensor 6 window, reducing the sensitivity of the infrared sensor 6 and interfering with the infrared sensor 6 signal, thereby ensuring the normal operation of the infrared sensor 6. The infrared sensor 6 detects the flame. After the test, the signal processor 22 of the console 21 can contact and process the detection signal of the infrared sensor 6. When a flame is generated inside the main body 1, turning the dial 20 can drive the worm 19 to rotate and make it mesh with the worm wheel 18 to drive the worm wheel 18 to rotate. When the worm wheel 18 rotates, it drives the rotating shaft 16 to rotate and makes the rotating shaft 16 drive the gear 17 to rotate and mesh with the meshing plate 14, so as to achieve the purpose of allowing the baffle 3 to be raised and lowered in the sliding cavity 2 by meshing with the meshing plate 14, so as to use the baffle 3 to block the movement of the flame generated by the main body 1 to prevent people from being burned by the flame due to accidentally getting too close to the flame.
