DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below. All other embodiments obtained by the person skilled in the art without making creative efforts on the basis of the embodiments in the utility model belong to the protection scope of the utility model.

[0023] Please refer to Figures 1 to 4 A fire-fighting smoke gun smoke sensing detection instrument based on magnetic induction, the utility model provides a technical scheme:

[0024] Embodiment one: a fire-fighting smoke gun smoke sensing detection instrument based on magnetic induction, comprising probe 1, probe 2, connecting rod 3 and adjusting auxiliary assembly.

[0025] One end of probe 1 is connected with probe 2, and the other end of probe 1 is connected with connecting rod 3, and the other end of connecting rod 3 is movably inserted into the connecting groove 5 of hand-held rod 4, and adjusting auxiliary assembly is arranged on connecting rod 3.

[0026] Through the investigation and research of the detection process of the fire-fighting smoke gun smoke sensing detection instrument to the intelligent smoke detector, and combining the working principle of the intelligent smoke detector, it is concluded that the magnetic induction principle is used to replace the smoke generated by the current fire-fighting smoke gun smoke sensing detection instrument, which can improve the work efficiency, save the cost and reduce the unnecessary repeated actions in the work.

[0027] The intelligent smoke detector is mainly composed of a light emitting element and a light receiving element. The receiving and transmitting elements are installed in a small dark room, which can enter smoke but cannot enter light. When the receiving and transmitting elements are installed in a large open space, the smoke on the light path between the receiving and transmitting elements is detected. When smoke is generated, the infrared light beam of the infrared emitter tube is scattered by smoke particles, and the strength of the scattered light is proportional to the concentration of the smoke. Therefore, the strength of the infrared light beam received by the photosensitive tube will change, which is converted into an electric signal and finally into an alarm signal. According to the magnetic induction principle of the magnet, a strong magnet is used to generate a magnetic field to affect the strength of the infrared light beam received by the photosensitive tube, which is converted into an electric signal and finally into an alarm signal.

[0028] In the embodiment one, the adjusting auxiliary assembly comprises a positioning groove 6, a first movable groove 7, and a first movable block 8. The positioning groove 6 is fixedly arranged in the inner side wall of the handheld rod 4 at equal intervals, and the first movable groove 7 is fixedly arranged on the connecting rod 3 at equal intervals. The first movable block 8 is movably connected in the first movable groove 7.

[0029] One side of the first movable block 8 is provided with a positioning convex particle 9, and the positioning convex particle 9 is connected with the positioning groove 6 in the inner side wall of the handheld rod 4.

[0030] The inner side of the first movable groove 7 is provided with a second movable groove 12, and the second movable groove 12 is connected with the first movable groove 7 through the fixed groove 10.

[0031] In the embodiment two, the second movable groove 12 is movably connected with a second movable block 13, and the second movable block 13 is connected with the first movable block 8 through the movable rod 11.

[0032] The two groups of second movable blocks 13 in the second movable groove 12 are connected through the second spring 15. The second movable block 13 is provided with the first spring 14 at the connection position with the movable rod 11, and the other end of the first spring 14 is arranged in the first movable groove 7.

[0033] In use, the connecting rod 3 is adjusted according to the height to be detected, and a plurality of adjusting auxiliary assemblies are arranged on the connecting rod 3 to position the height after adjustment. The positioning convex particle 9 arranged on one side of the first movable groove 7 in the connecting rod 3 is first moved inward under the action of force until the height of the connecting rod 3 is adjusted and confirmed. Then, under the action of the first spring 14 and the second spring 15, the positioning convex particle 9 moves outward to the positioning groove 6 arranged in the inner side wall of the handheld rod 4 to complete the positioning.

[0034] The material cost of 6860 yuan per year of smoke liquid and battery is saved. When the intelligent smoke detector is detected by the fire smoke gun smoke detection instrument, the battery is a rechargeable battery of about 140 yuan, and the smoke liquid needs to be replaced once every 150 points. According to 300 smoke detection points of each station, the smoke liquid of two stations needs to be replaced. The material cost of 20 yuan per station is needed for each replacement, and the material cost of 40 yuan per station is needed for each station. At present, 168 stations of Qingdao subway are running, and the material cost of 6720 yuan per year is needed for each station.

[0035] The working time is saved, the labor cost is reduced, and the working efficiency is improved. The line network can save 378 hours per year. The test time of a single point is reduced from about 30 seconds to 3 seconds, and 27 seconds of time can be saved for each point. 300*(30-3) = 8100 seconds, about 2.25 hours. The time of 168 stations of the whole line network can be saved by 168*2.25 = 378 hours (according to 8 hours of work per day, 47.25 days of working hours can be saved per year);

[0036] The working time is saved, the labor cost is reduced, and the working efficiency is improved. The line network can save 378 hours per year. The test time of a single point is reduced from about 30 seconds to 3 seconds, and 27 seconds of time can be saved for each point. 300*(30-3) = 8100 seconds, about 2.25 hours. The time of 168 stations of the whole line network can be saved by 168*2.25 = 378 hours (according to 8 hours of work per day, 47.25 days of working hours can be saved per year).

[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
