Description

Technical field:

[0001] The invention relates to a safety detection device for a flame detector of a fire-fighting facility. Background technology:

[0002] In the field of building fire protection facilities, the detection of flame detectors of building fire protection facilities is mostly carried out by using infrared light sources or ultraviolet light sources or a combination of the two to simulate flames. However, the simulated light source has the limitation that it cannot completely simulate the flame effect, which often causes the flame detector to not respond to the simulated light source, making the detection result uncertain; if an open flame ignition detection method is used, it is easy to cause on-site safety problems. For this reason, it is necessary to develop a safe detection device for flame detectors of building fire protection facilities. Summary of the invention:

[0003] In order to solve the problems encountered in the detection of flame detectors in the past, the present application provides a safety detection device for a flame detector of a fire-fighting facility, characterized in that: a fire-starting device 2 is arranged in a quartz glass cover 1 with a single end opening, the fire-starting device 2 has one or more burners 3, the fire-starting device 2 is on a non-combustible rubber body 4, the outer periphery of the non-combustible rubber body 4 is sealed and connected to the inner periphery of the open end of the quartz glass cover 1, the non-combustible rubber body 4 is equipped with an adjustable one-way valve 5, the air inlet of the adjustable one-way valve 5 leads to the quartz glass cover 1, and the air outlet of the adjustable one-way valve 5 leads to the external space, the non-combustible rubber body 4 has an air outlet 6 and an air inlet 7, the air outlet 6 is connected to one end of a valve 8, and the other end of the valve 8 leads to the external space, the air inlet 7 is connected to one end of a valve 9, and the other end of the valve 9 is connected to an air outlet 11 of a blower 10.

[0004] The quartz glass cover 1 can transmit infrared and ultraviolet rays in the flame, and will not affect the flame detector's detection of the flame inside the quartz glass cover 1. The purpose of isolating the air convection between the quartz glass cover 1 and the external space is to prevent the flame of the quartz glass cover 1 from causing the combustion of combustible gases or combustibles in the external space. The number of burners 3 used is related to the detection distance, and a suitable setting can enable the flame detector to respond to the flame of the quartz glass cover 1. During the time period from the start of normal detection of the flame detector to the normal response of the flame detector, the amount of oxygen in the quartz glass cover 1 should ensure that the flame burning in the quartz glass cover 1 is always burning. In this way, the size of the space inside the quartz glass cover 1 can be set. The pressure relief function of the adjustable one-way valve 5 is to prevent the pressure of the quartz glass cover 1 from being too high during the combustion process. When the gas pressure inside the transparent quartz glass cover 1 is higher than a certain value of the atmospheric pressure in the external space, the adjustable one-way valve 5 relieves pressure to the external space and resets.

[0005] Valve 8 and valve 9 have two functions: in working mode 1, valve 8 and valve 9 are both closed. The flame of the burner 3 in the quartz glass cover 1 can only be maintained for a certain period of time. The flame burning time must be greater than the time it takes for the flame detector to respond normally from detecting the flame. If the flame detector can respond, it is normal, otherwise it is unqualified. After detection, fresh air is introduced through valve 8 and valve 9 to replace the exhaust gas after combustion in the quartz glass cover 1. In working mode 2, valve 8 and valve 9 are both open. The blower air inlet 12 is connected to the external space. During the combustion process, the blower is used to introduce a proper amount of fresh air, which can achieve a longer period of continuous flame combustion.

[0006] The above-mentioned safety detection device of a fire-fighting facility flame detector can be improved as follows: the air inlet 12 of the blower 10 is connected to the air outlet 14 of the one-way valve 13, the air inlet 15 of the one-way valve 13 is connected to the air outlet 17 of an inflatable sealed airbag 16, the air inlet 18 of the inflatable sealed airbag 16 is connected to the air outlet 20 of the valve 19, the air inlet 21 of the valve 19 is connected to the external space, and a combustible gas detector 22 is provided inside the inflatable sealed airbag 16.

[0007] The function of the blower 10 is to provide gas from the inflatable sealed airbag 16. When the valve 19 is opened, the interior of the inflatable sealed airbag 16 is communicated with the external space.

[0008] The function of the one-way valve 13 is to make the air in the inflatable sealed airbag 16 flow only from the inflatable sealed airbag 16 to the air inlet 12 of the blower 10 , but not flow in the reverse direction.

[0009] The function of the inflatable sealing airbag 16 is to store a certain amount of air to adapt to the use in conjunction with the one-way valve 13, the combustible gas detector 22 and the valve 19 in an environment where combustible gas may exist.

[0010] The function of the valve 19 is to connect or isolate the air in the expandable sealed airbag 16 from the external space. When there is no combustible gas in the working environment, the valve 19 is always opened, the blower 10 can run continuously, and the flame of the burner 3 in the quartz glass cover 1 can burn for a long time.

[0011] The function of the combustible gas detector 22 is that when the detection device is used in an environment where combustible gas may exist, each time the air entering the space inside the quartz glass cover 1 as air providing oxygen for combustion must first be detected by the combustible gas detector 22, and the blower 10 can pump it into the quartz glass cover 1 under a safe state.

[0012] The inflatable sealed airbag 16 is in an automatically inflated state in a natural state, and inhales air from the external space through the air inlet 21 of the valve 19 .

[0013] In working mode 2, valves 8 and 9 are both open. When the inflatable sealed airbag 16 is in a naturally inflated state, the inflatable sealed airbag 16 is inflated. After it is full of air, valve 19 is closed to cut off the air inside the inflatable sealed airbag 16 from being connected to the outside space. The air inside the inflatable sealed airbag 16 is detected by the combustible gas detector 22. If the combustible gas detector 22 does not alarm, the blower 10 can be started to send the safe air in the inflatable sealed airbag 16 into the quartz glass cover 1. During this process, the inflatable sealed airbag 16 is slowly exhausted and deflated. When the exhaust is completed, the flame of the quartz glass cover 1 will go out. Complete one test; when used again, open valve 19 again to allow the inflatable sealed airbag 16 to be connected to the outside space and automatically inflate and inflate. Close valve 19 after it is fully inflated. The combustible gas detector 22 detects the air inside the inflatable sealed airbag 16. If there is no alarm, the blower can be started for the next ignition test.

[0014] Since the invention adopts isolated real flame as the detection source of the flame detector, it is effective, accurate and safe. Description of the drawings:

[0018] Embodiment 1:

[0019] See Figure 2 , Figure 3The present application provides a safety detection device for a flame detector of a fire-fighting facility, characterized in that: a fire-starting device 2 is arranged in a quartz glass cover 1 with a single end opening, the fire-starting device 2 has three burners 3, the fire-starting device 2 is on a non-combustible rubber body 4, the fire-starting device 2 has its own power supply and control system, uses liquid fuel for a general lighter, and has an overall explosion-proof structure. The fire-starting device 2 is ignited by remote control electronic ignition, the outer periphery of the non-combustible rubber body 4 is sealed and connected to the inner periphery of the opening end of the quartz glass cover 1, the non-combustible rubber body 4 is equipped with an adjustable one-way valve 5, the air inlet of the adjustable one-way valve 5 leads to the inside of the quartz glass cover 1, and the air outlet of the adjustable one-way valve 5 leads to the external space, the non-combustible rubber body 4 has an air outlet 6 and an air inlet 7, the air outlet 6 is connected to one end of a valve 8, and the other end of the valve 8 leads to the external space, the air inlet 7 is connected to one end of a valve 9, and the other end of the valve 9 is connected to the air outlet 11 of a blower 10. When only the oxygen in the original air of the quartz glass cover 1 is used to maintain combustion (in working mode 1, valves 8 and 9 are closed), the fire-making device 2 will automatically extinguish due to lack of oxygen 10 seconds after ignition. If the burning time needs to be extended, working mode 2 is adopted, valves 8 and 9 are opened, and the blower 10 is started to introduce fresh air to maintain combustion. The blower 10 is a speed-adjustable type. After each test, the blower should send fresh air to purge the inside of the quartz glass cover 1 once.

[0020] The quartz glass cover 1 can transmit infrared and ultraviolet rays in the flame, and will not affect the flame detector's detection of the flame inside the quartz glass cover 1. The purpose of isolating the air convection between the quartz glass cover 1 and the external space is to prevent the flame of the quartz glass cover 1 from causing the combustion of combustible gases or combustibles in the external space. Three burners are used, which are arranged horizontally facing the flame detector. During the period from the start of normal detection of the flame detector to the normal response of the flame detector, the amount of oxygen in the quartz glass cover 1 can ensure that the flame burning in the quartz glass cover 1 is always burning. In this way, the size of the space inside the quartz glass cover 1 can be set. The pressure relief function of the adjustable one-way valve 5 is to prevent the pressure of the quartz glass cover 1 from being too high during the combustion process. When the gas pressure inside the transparent quartz glass cover 1 is higher than a certain value of the atmospheric pressure of the external space, the adjustable one-way valve 5 relieves pressure to the external space and resets.

[0021] Embodiment 2:

[0022] See Figure 1 When there may be combustible gas at the detection site, use Figure 1 In this way, based on the application of Example 1, the air inlet 12 of the blower 10 is connected to the air outlet 14 of the one-way valve 13, the air inlet 15 of the one-way valve 13 is connected to the air outlet 17 of an inflatable sealed airbag 16, the air inlet 18 of the inflatable sealed airbag 16 is connected to the air outlet 20 of the valve 19, the air inlet 21 of the valve 19 is connected to the external space, and a combustible gas detector 22 is provided inside the inflatable sealed airbag 16.

[0023] The function of the blower 10 is to provide gas from the inflatable sealed airbag 16. When the valve 19 is opened, the interior of the inflatable sealed airbag 16 is communicated with the external space. The blower 10 has its own power supply and control system, and an overall explosion-proof structure.

[0024] The function of the one-way valve 13 is to make the air in the inflatable sealed airbag 16 flow only from the inflatable sealed airbag 16 to the air inlet 12 of the blower 10 , but not flow in the reverse direction.

[0025] The function of the inflatable sealing airbag 16 is to store a certain amount of air to adapt to the use in conjunction with the one-way valve 13, the combustible gas detector 22 and the valve 19 in an environment where combustible gas may exist.

[0026] The function of the valve 19 is to connect or isolate the air in the expandable sealed airbag 16 from the external space. When there is no combustible gas in the working environment, the valve 19 is always opened, the blower 10 can run continuously, and the flame of the burner 3 in the quartz glass cover 1 can burn for a long time.

[0027] The function of the combustible gas detector 22 is that when the detection device is used in an environment where combustible gas may exist, each time the air entering the space inside the quartz glass cover 1 as air providing oxygen for combustion must first be detected by the combustible gas detector 22, and the blower 10 can deliver it into the quartz glass cover 1 under a safe state.

[0028] The inflatable sealed airbag 16 is in an automatically inflated state in a natural state, and inhales air from the external space through the air inlet 21 of the valve 19 .

[0029] When the inflatable sealed airbag 16 is in a naturally inflated state, the inflatable sealed airbag 16 is inflated. After being filled with air, the valve 19 is closed to cut off the air inside the inflatable sealed airbag 16 from being connected to the external space. The air inside the inflatable sealed airbag 16 is detected by the combustible gas detector 22. If the combustible gas detector 22 does not alarm, the valves 8 and 9 can be opened, the blower 10 can be started, and the speed of the blower 10 can be appropriately adjusted to send the safe air in the inflatable sealed airbag 16 into the quartz glass cover 1 to maintain the normal combustion of the flame of the burner 3. In this process, the inflatable sealed airbag 16 is slowly exhausted and deflated. When the exhaust is completed, the flame of the quartz glass cover 1 will be extinguished. Complete one test; when used again, open the valve 19 again to allow the inflatable sealed airbag 16 to be connected to the external space and automatically inflated and inflated, and start the blower 10 to purge the inside of the quartz glass cover 1. Subsequently, the valve 19 is closed after the inflatable sealed airbag 16 is connected to the external space and automatically inflated and inflated and fully inflated. The combustible gas detector 22 detects the air inside the inflatable sealed airbag 16. If there is no alarm, the blower can be started to detect the next ignition. The internal maximum volume of the inflatable sealed airbag 16 can store enough air for normal detection each time.

[0030] The rest is the same as in Example 1.
