Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting facility detection, in particular to a detection device for a fire-fighting facility detector. Background Art

[0002] Fire safety is a top priority in social development. In order to meet the requirements of fire protection conditions, buildings are equipped with many fire protection facilities, such as fire hoses, fire extinguishers, fire axes and fire shovels. In order to detect fire, smoke sensors and temperature sensors are indispensable detection devices.

[0003] The daily maintenance and inspection of smoke sensors are very important. At present, when the traditional detection device is in operation, the smoke generated by the detection fills the detection environment, affecting the air quality of the detection environment. Therefore, it is necessary to design a detection device for fire protection facility detectors to reduce the impact of detection smoke on the environment.

[0004] For example, a detection device for a fire protection facility detector with Chinese patent publication number CN218098770U includes a box body, a partition is fixedly connected to the inner wall of the box body, the partition divides the inner cavity of the box body into a detection chamber and an exhaust gas treatment chamber, a fan is fixedly installed at the air inlet opened on the side wall of the detection chamber of the box body, a first mounting seat and a second mounting seat are fixedly connected to the top of the inner wall of the detection chamber, when in use, the smoke generating device is placed on the placement pad, the fan blows up the generated smoke, the smoke sensor to be detected installed on the second mounting seat detects the smoke, confirms whether the smoke sensor is used normally, the transmitted smoke enters the liquid in the liquid storage tank through the first conduit and the second conduit, the liquid in the liquid storage tank preliminarily absorbs the transmitted smoke, and the absorbed gas is discharged after secondary filtration through the filter element in the filter mechanism, thereby reducing the interference and pollution of the smoke to the detection environment and improving the quality of the working environment during detection.

[0005] However, the device can only be used on the ground during actual use. For the smoke sensor installed on the roof of the house, the smoke generated by its detection will still overflow into the air. In addition, due to the long distance between the device and the smoke sensor, it takes a certain amount of time for the smoke to reach the smoke sensor. The smoke generated during this period cannot be completely cleaned up, which has certain disadvantages when used.

[0006] Therefore, a detection device for a fire-fighting facility detector is designed to solve the problem of low detection efficiency of the detection device for the fire-fighting facility detector in the prior art and the problem of smoke escaping to the outside of the detection device and affecting the surrounding air.

[0013] The smoke generating part includes a support spring and a cigarette lighter. The support spring is vertically arranged inside the second accommodating cavity. The upper end of the support spring is fixedly connected to one side of the cigarette lighter. The cigarette lighter is located in the first accommodating cavity. The bottom of the first accommodating cavity is detachably connected with a sealing plug.

[0018] The beneficial effect of this solution is that a detection device for a fire protection facility detector has the following benefits:

[0019] The main body of the detection device can be directly extended to the lower side of the smoke sensor through the rod body, and smoke is generated by the smoke generating part. The smoke directly enters the detection cover through the smoke inlet channel, which can effectively prevent the detection smoke from being emitted into the air, reduce the impact on the surrounding air environment, and improve the detection efficiency of the smoke sensor;

[0037] Under the action of the support spring 17 , the cigarette lighter 18 can always press the cigarette lighter rod 16 downward, making it easier to contact and ignite the cigarette lighter rod 16 .

[0038] like Figure 4 As shown, the lower end of the smoke inlet channel 5 is connected to the top of the first accommodating chamber 14, and the upper end of the smoke inlet channel 5 is connected to the bottom of the detection cover 2;

[0039] An air inlet passage 20 is provided between the second accommodating chamber 15 and the outer side of the detection device body 1 , and an air inlet solenoid valve 21 is provided inside the air inlet passage 20 .

[0042] Directions:

[0043] When the device is used, it is used in conjunction with a retractable support rod, and the upper end of the support rod is sleeved with the connecting sleeve 25 during use.

[0044] Place the cigarette lighter rod 16 in the first receiving chamber 14 and tighten the sealing plug 19;

[0045] The detection device body 1 is lifted upwards by the support rod, so that the detection cover 2 buckles the smoke sensor, and the detection cover 2 is coaxially arranged with the smoke sensor;

[0046] By extending the telescopic rod 13, the telescopic rod 13 pushes the support ring 12 upward, so that the sealing cover 3 moves upward until it is close to the wall, and the smoke sensor is completely buckled inside the sealing cover 3;

[0047] Open the air inlet solenoid valve 9 to allow external air to enter the detection cover 2 through the air inlet solenoid valve 9, so that the air pressure inside the detection cover 2 is balanced with the external air pressure, and push the support rod to make the detection cover 2 press against the wall;

[0048] The smoke inlet solenoid valve 22 and the smoke inlet pump 23 are closed, and the smoke exhaust pump 24 is running, so that the gas inside the sealing cover 3 is pumped outward, and the inside of the sealing cover 3 presents a negative pressure or even a vacuum state, so that the sealing cover 3 is closely attached to the outside of the smoke sensor;

[0055] The smoke inlet solenoid valve 22, the smoke exhaust pump 24 and the air inlet solenoid valve 21 are closed, and the smoke inlet pump 23 and the exhaust pump are operated, so that the smoke inside the first accommodating chamber 14 and the second accommodating chamber 15 is discharged into the filter block 6 through the smoke inlet channel 5, the connecting pipe 7 and the smoke exhaust channel 4, and is discharged after being filtered by the filter block 6. The first accommodating chamber 14 and the second accommodating chamber 15 are deprived of oxygen, and the cigarette rod 16 is extinguished.
