Description

Technical Field

[0001] The invention relates to a networked detection device and method for a fixed carbon monoxide alarm, belonging to the technical field of metallurgical safety equipment and methods. Background Art

[0002] According to the 2023 version of the "Criteria for Determining Major Accident Hazards in Industrial and Trade Enterprises", "Article 3 (VI) Meeting rooms, activity rooms, lounges, operating rooms, shift rooms, locker rooms and other 6 types of places where people gather near gas production, recovery and purification, pressurized mixing, storage and use facilities, as well as places and locations where gas leakage and accumulation may occur, are not equipped with fixed carbon monoxide concentration monitoring and alarm devices, or the monitoring data is not connected to 24-hour manned places." and "Article 14 The monitoring, alarm, protection and other facilities, equipment and devices directly related to production safety in the circumstances listed in this standard shall be guaranteed to operate normally and be used. Failure or ineffectiveness shall be determined as a major accident hazard." Safety management personnel and post inspection personnel need to check the networking status of fixed carbon monoxide detection and alarm devices during daily inspections and inspections. The inspection method is generally to use low-concentration carbon monoxide gas to make the fixed carbon monoxide detection device detect carbon monoxide and then activate the sound and light alarm. If the carbon monoxide alarm host in the 24-hour manned place activates the sound and light alarm at the same time, it means that the fixed carbon monoxide detection device is connected to the network normally. If any of the two alarm positions does not alarm, it means that the network is abnormal and there is a major accident hazard.

[0003] However, the two commonly used inspection methods are: 1. Place a lit cigarette at the detection port of a fixed carbon monoxide detection device, and use the carbon monoxide produced when the cigarette is lit to check the networking status of the fixed carbon monoxide detection device. 2. Place the gas outlet of a lighter at the detection port of a fixed carbon monoxide detection device, release the liquefied gas in the lighter for 2-3 seconds (without ignition), then light the lighter and extinguish it in the shortest time, and use the carbon monoxide produced by the incomplete combustion of the combustible gas released by the lighter to detect the networking status of the fixed carbon monoxide detection device.

[0004] However, areas where fixed carbon monoxide detection devices are installed are generally flammable and explosive areas where open flames are prohibited. Therefore, both of the above-mentioned inspection methods involve illegal operations and are relatively dangerous. Summary of the invention

[0005] The purpose of the present invention is to provide a networked detection device and method for a fixed carbon monoxide alarm. By collecting low-concentration carbon monoxide gas in non-flammable and explosive areas, it is only necessary to carry the low-concentration carbon monoxide gas to the fixed carbon monoxide alarm for detection, thereby avoiding the safety hazard of creating open flames in flammable and explosive areas. The collected carbon monoxide gas is a low-concentration gas, thereby avoiding the risk of carbon monoxide poisoning. The device has a simple structure, and most of the material is plastic, and the cost is low. The device avoids the high cost and high risk of using carbon monoxide standard gas, improves the safety of daily inspections by safety management personnel and post inspection personnel, and effectively solves the above-mentioned problems existing in the background technology.

[0006] The technical solution of the present invention is: a fixed carbon monoxide alarm networked detection device, comprising a handle, a lighter, a battery, a button, a fan, a windshield and an airbag, the handle is connected below the windshield, the lighter and the battery are placed in the handle, the handle is not closed at the lighter push switch position, the button is arranged on the side of the end position of the lighter push switch, the fan and the airbag are respectively arranged on both sides of the upper part of the windshield, and the battery and the button are connected to the fan motor through wires.

[0007] A lighter air outlet is arranged in the middle of the top of the handle; the interior of the handle is divided into two cavities front and back, the lighter is placed in the front cavity, and the battery is placed in the back cavity; a cover plate is arranged at the front and back of the handle respectively, and the cover plate is a switchable structure, and the position matches the lighter and the battery respectively.

[0008] The size setting of the button is triggered by fully pressing the lighter push switch.

[0009] The wind shield is provided with three holes, the lower small hole matches the position of the lighter outlet hole in the handle, one side hole has no outer edge and is connected to the front of the fan, and the other side hole is provided with an outer edge protruding outwards, and the airbag is sleeved on the outer edge.

[0010] The airbag is made of two layers of light and thin plastic material, with a thin rope arranged in the middle, and both ends of the thin rope extend out of the airbag from a small hole on the two layers of light and thin plastic.

[0011] It also includes a fan casing, which is fixedly connected to the wind shield, and the fan is rotatably arranged in the fan casing, and the fan casing is a fence structure.

[0012] A method for detecting a fixed carbon monoxide alarm through networking comprises the following steps: (1) Insert the battery and lighter into the handle; (2) Gently press the lighter push switch to allow the combustible gas in the lighter to enter the wind shield through the small hole between the handle and the wind shield; (3) After the flammable gas fills the windshield, press the lighter switch to ignite the lighter. Release the finger pressing the lighter at the moment of ignition, and the flame will immediately go out. The button of the lighter will be triggered at the moment of ignition, turning on the fan to inflate the airbag; (4) After the airbag is inflated, the thin rope at the airbag opening is tightened to separate the airbag from the windshield. The airbag opening is closed at the same time as the airbag is separated from the windshield; (5) Press the button to turn off the fan; (6) Point the inflated air bag toward the detection port of the fixed carbon monoxide alarm, release the gas, and conduct detection.

[0013] In step (2), the pressing force of the lighter switch should be moderate, so that combustible gas can be sprayed out but no flame can be ignited.

[0015] In the step (4), the airbag is filled in 2-3 seconds under the action of the fan.

[0016] In step (6), if the fixed carbon monoxide detection device activates the sound and light alarm, and the carbon monoxide alarm host in the 24-hour manned location activates the sound and light alarm at the same time, it means that the fixed carbon monoxide detection device is connected to the network normally. If no alarm is given at either of the two locations, it means that the network is abnormal and there is a major accident hazard.

[0017] The beneficial effects of the present invention are as follows: by collecting low-concentration carbon monoxide gas in non-flammable and explosive areas, it is only necessary to carry the low-concentration carbon monoxide gas to a fixed carbon monoxide alarm for detection, thereby avoiding the safety hazard of creating open flames in flammable and explosive areas, and the collected carbon monoxide gas is a low-concentration gas, thereby avoiding the risk of carbon monoxide poisoning.

[0020] A fixed carbon monoxide alarm network detection device comprises a handle 1, a lighter 2, a battery 3, a button 4, a fan 5, a wind shield 6 and an air bag 7, wherein the handle 1 is connected below the wind shield 6, the lighter 2 and the battery 3 are placed in the handle 1, the handle 1 is not closed at the lighter push switch position, the button 4 is arranged on the side of the end position of the lighter push switch, the fan 5 and the air bag 7 are respectively arranged on both sides of the upper part of the wind shield 6, and the battery 3 and the button 4 are connected to the motor of the fan 5 through wires.

[0021] A lighter air outlet is provided in the middle of the top of the handle 1; the interior of the handle is divided into two cavities front and back, the lighter 2 is placed in the front cavity, and the battery 3 is placed in the back cavity. A cover plate is provided at the front and back of the handle 1, and the cover plate is a switchable structure, and the position matches the lighter 2 and the battery 3 respectively.

[0022] The size of the button 4 is set to trigger when the lighter push switch is fully pressed.

[0023] The wind shield 6 is provided with three holes, the lower small hole matches the position of the lighter outlet hole in the handle 1, one side hole has no outer edge and is connected to the front of the fan 5, and the other side hole is provided with an outer edge protruding outward, and the airbag 7 is sleeved on the outer edge.

[0024] The airbag 7 is made of two layers of thin plastic material, with a thin rope arranged in the middle, and both ends of the thin rope extend out of the airbag from a small hole in the two layers of thin plastic.

[0025] It also includes a fan casing, which is fixedly connected to the wind shield, and the fan 5 is rotatably arranged in the fan casing, and the fan casing is a fence structure.

[0026] A method for detecting a fixed carbon monoxide alarm through networking comprises the following steps: (1) Insert the battery and lighter into the handle; (2) Gently press the lighter push switch to allow the combustible gas in the lighter to enter the wind shield through the small hole between the handle and the wind shield; (3) After the flammable gas fills the windshield, press the lighter switch to ignite the lighter. Release the finger pressing the lighter at the moment of ignition, and the flame will immediately go out. The button of the lighter will be triggered at the moment of ignition, turning on the fan to inflate the airbag; (4) After the airbag is inflated, the thin rope at the airbag opening is tightened to separate the airbag from the windshield. The airbag opening is closed at the same time as the airbag is separated from the windshield; (5) Press the button to turn off the fan; (6) Point the inflated air bag toward the detection port of the fixed carbon monoxide alarm, release the gas, and conduct detection.

[0027] In step (2), the pressing force of the lighter switch should be moderate, so that combustible gas can be sprayed out but no flame can be ignited.

[0028] In the step (3), after pressing the lighter's push button for 2-3 seconds, the combustible gas fills the windshield.

[0029] In the step (4), the airbag is filled in 2-3 seconds under the action of the fan.

[0030] In step (6), if the fixed carbon monoxide detection device activates the sound and light alarm, and the carbon monoxide alarm host at the 24-hour manned location activates the sound and light alarm at the same time, it means that the fixed carbon monoxide detection device is connected to the network normally. If no alarm is given at either of the two locations, it means that the network is abnormal and there is a major accident hazard. In actual application, the handle 1 is connected to the bottom of the windshield 6, and a lighter outlet is left in the middle for combustible gas and flame to pass through. The handle 1 is divided into two cavities front and back. The cavity in the front of the handle is used to place the lighter 2. The handle 1 is not closed at the lighter push switch position to facilitate pressing. A button 4 is set on the side of the lighter push switch. The button 4 is set smaller. When the lighter push switch is not fully pressed, the button 4 cannot be touched. The button 4 can only be pressed when the lighter push switch is fully pressed (that is, the fire is lit). When the button 4 is pressed, the fan 5 is turned on. When the button 4 is pressed again, the fan 5 is turned off. The cavity behind the handle is used to place the battery 3. There is an openable and closable cover at the front and back of the handle 1 for replacing the battery and the lighter. The battery 3 and the button 4 are connected to the motor of the fan 5 through wires.

[0031] The wind shield 6 has three holes, the lower small hole is located at the lighter outlet position in the handle, one side hole has no outer edge and is connected to the front of the fan 5, and the other side hole has an outer edge protruding outward for covering the airbag 7. The airbag 7 is not fixed to the wind shield 6, and is only covered on the outer edge of the other side hole by the telescopic effect of the airbag 7. The airbag can be filled in about 2-3 seconds when the fan is turned on. The airbag is two layers of thin plastic with a thin rope in the middle. Both ends of the thin rope extend out of the airbag from a small hole on the two layers of thin plastic. When the airbag is full, the airbag mouth can be closed by tightening the thin rope.

[0032] The fan is connected with the hole on the side without the outer edge of the wind shield, the fan shell is fixed to the wind shield, the fan can rotate freely in the fan shell, and the fan shell is a fence structure for easy ventilation.

[0033] A method for detecting a fixed carbon monoxide alarm through networking comprises the following steps: (1) Insert the battery and lighter into the handle; (2) Gently press the lighter's push button to allow the combustible gas in the lighter to enter the wind shield through the lighter's air outlet and the small hole under the wind shield. The pressure should be moderate so that the combustible gas can be ejected but no flame can be ignited.

[0034] (3) After pressing for 2-3 seconds as required in step (2), the combustible gas fills the windshield, and the lighter switch is pressed to ignite the lighter. The finger pressing the lighter is released at the moment of ignition, and the flame is immediately extinguished. Since the button is touched when the lighter is pressed to ignite, the fan is turned on.

[0035] (4) The airbag will inflate in 2-3 seconds under the action of the fan. After the airbag inflates, the thin rope at the airbag opening is tightened, and the airbag is separated from the windshield and the airbag opening is closed.

[0036] (5) Press the button to turn off the fan.

[0037] (6) Point the inflated airbag toward the detection port of the fixed carbon monoxide alarm and release the gas. If the fixed carbon monoxide detector activates the sound and light alarm, and the carbon monoxide alarm host in the 24-hour manned location activates the sound and light alarm at the same time, it means that the fixed carbon monoxide detector is connected to the network normally. If there is no alarm at either position, it means that the network is abnormal and there is a major accident hazard.

[0038] The working principle of the present invention is: when the combustible gas is in an environment with poor air circulation (such as in a windshield), the combustion of the combustible gas will be incomplete, and some carbon monoxide gas will be produced. The fixed carbon monoxide alarm is extremely sensitive to carbon monoxide. When the carbon monoxide content in the air exceeds 24ppm (i.e., the volume concentration of 24 parts per million), the sound and light alarm device can be activated. The combustible gas sprayed by the lighter within 2-3 seconds will produce a carbon monoxide concentration of about 200ppm after incomplete combustion, and it can also be above 24ppm after being diluted by a fan, which can achieve the purpose of testing the networking status of the fixed carbon monoxide alarm.

[0039] The present invention has the advantages of scientific and reasonable technical scheme, simple and practical structure, convenient daily maintenance and replacement, etc., avoids the safety hazard of creating open flames in flammable and explosive areas, and the collected carbon monoxide gas is low-concentration gas, avoiding the risk of carbon monoxide poisoning. The device has a simple structure, and most of the material is plastic, and the cost is low. It avoids the high price and high risk of using carbon monoxide standard gas to detect the networking of fixed carbon monoxide alarms, and realizes the safety and compliance of networked detection of fixed carbon monoxide alarms, improves the safety of daily inspections by safety management personnel and post inspection personnel, facilitates daily inspections by safety management personnel and post inspection personnel, and is beneficial to reducing major accident hazards in the production process of enterprises.
