Especially during the annual inspection of fire equipment, since all intelligent smoke detectors need to be tested, it is necessary to continuously add smoke liquid, which is a repetitive action and wastes resources, and does not conform to the principle of motion economy at work.

[0005] (2) When using the fire smoke gun smoke detection instrument to detect the fire smoke gun smoke detection instrument, generally a single point needs to be continuously supplied with smoke for about 30 seconds, and it must be aimed at the smoke detection part of the intelligent smoke detector.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 14 A fire smoke gun smoke detection instrument includes a regulating rod body, a detection head component and auxiliary components.

[0041] The regulating rod body includes a first support rod 1 and a second support rod 2; a regulating screw 12 is fixedly arranged at one end of the first support rod 1; a regulating connecting groove 21 is arranged at one end of the second support rod 2, and the regulating screw 12 is threadedly connected to the regulating screw 12, and a limited stop plate 22 is fixedly arranged at the side position of the other end of the second support rod 2; the detection head component in this scheme is arranged at one end of the second support rod 2, and the auxiliary component is sleeved on the second support rod 2.

[0042] This solution detects the smoke detector by setting a strong magnet 305. For traditional detection devices, the intelligent smoke detector is generally detected by generating smoke to see whether it will alarm to determine whether it is faulty; the smoke sensing alarm principle of the intelligent smoke detector is: the intelligent photoelectric smoke detector is mainly composed of two parts: the light-emitting element and the light-receiving element; the receiving and transmitting elements are installed in a small dark room, where smoke can enter but light cannot enter. 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 transmitting tube is scattered by the smoke particles, and the strength of the scattered light is proportional to the concentration of the smoke, so the strength of the infrared light beam received by the photosensitive tube will change, converted into an electrical signal, and finally converted into an alarm signal. In the actual testing of intelligent smoke detectors, the detectors generally alarm through photoelectric conduction, that is, they generally alarm through smoke induction. However, for testing purposes, the detectors themselves also have magnetic conduction capabilities. In order to facilitate testing and extend the service life of the device, this solution uses a strong magnet 305 to generate a magnetic field based on the magnetic induction principle of a magnet to affect the strength of the infrared light beam received by the photosensitive tube, convert it into an electrical signal, and finally convert it into an alarm signal to achieve the same test effect as smoke.

[0043] The present invention detects by setting a detection head component, wherein a through hole is set at the center of a cross-shaped carrier plate 301 in the detection head component, and the cross-shaped carrier plate 301 is fixedly set at one end of the second support rod 2 by a fastening bolt 302, and an elbow portion 304 is fixedly set at the four ends of the cross-shaped carrier plate 301; a mounting connection hole body 303 is symmetrically set in the cross-shaped carrier plate 301, and a strong magnet 305 is fixedly set on the inner side wall of the elbow portion 304 by a mounting screw 306, and the mounting screw 306 is threadedly connected with a fixing nut 307 to fix the strong magnet 305 on the inner side of the elbow portion 304. In the present invention, the equidistant There are four groups arranged in a ring shape, and six or eight groups can also be set in actual use. The strong magnet 305 is connected and fixed by installing screws 306 and fixing nuts 307, and is detachably arranged to facilitate subsequent replacement and maintenance. On the other hand, multiple groups of strong magnets 305 are equidistantly arranged in a ring shape, and their positions are adjusted by adjusting the rod body to send the strong magnet 305 to the vicinity of the intelligent smoke detector. The strong magnet 305 works when it reaches the detection area. The purpose of setting multiple groups of strong magnets 305 is to allow the strong magnet 305 to cover the test area faster, thereby improving its test work efficiency.

[0044] In order to better control, this solution adopts a control rod body to control the detection head component. The staff holds the first support rod 1 to lift the detection head component. If the position of the intelligent smoke detector is higher, the overall strength of the control rod body is increased by rotating the first support rod 1 or the second support rod 2. The first support rod 1 and the second support rod 2 are threadedly connected with the control connecting groove 21 through the control screw 12. After the detection work is completed, the first support rod 1 and the second support rod 2 can also be disassembled to facilitate their subsequent storage and placement.

[0045] In order to better realize the detection work, that is, when the staff lifts the detection head component to detect the detector, the detection head component will slowly approach the detector. If the process is not well controlled, it may cause the detection head component to touch the detector, which will not only damage the detector, but also the detection head component. Therefore, the present scheme also provides an auxiliary component to assist the detection work. The auxiliary bearing 402 is embedded in the supporting ring body 401 of the auxiliary component, and the outer wall of the supporting ring body 401 is equidistantly fixed with support The support bar 403 is provided with a connecting pin 404 at the other end, and the support bar 403 is arranged in an annular shape at equal distances on the outer wall of the bearing ring body 401. An auxiliary spring 405 is fixedly provided at one end of the connecting pin 404, and a docking block 406 is fixedly provided at the other end of the auxiliary spring 405, and a docking thread groove 407 is provided at one end of the docking block 406; the connecting pin 404 is adapted to be plugged in with a fixed sleeve 408, and the fixed sleeve 408 is fixedly provided at one end of the supporting ring body 409 at equal distances, and the other end of the supporting ring body 409 is arranged at equal distances There is an accommodating cavity 410, in which an auxiliary jack body 411 is arranged, the auxiliary jack body 411 is connected with the fixed sleeve 408, the docking screw 412 passes through the auxiliary jack body 411 and is threadedly connected with the docking thread groove 407, the connection pin 404 and the fixed sleeve 408 are arranged at corresponding positions and the number of sets is the same; when performing detection work, the staff lifts the detection head component and the auxiliary component by adjusting the rod body, and the support ring body 409 in the auxiliary component will first contact the indoor roof panel, and the support ring body 409 will detect The detector is covered, and then the detection head component is slowly moved up so that the strong magnet 305 in the detection head component slowly approaches the detector and reaches the appropriate position. If rotation adjustment is required to make the strong magnet 305 perform better detection, the first support rod 1 can be directly rotated. The auxiliary bearing 402 in the auxiliary component is fixedly embedded in the inner wall of the bearing ring body 401, and the auxiliary bearing 402 is sleeved and installed on the second support rod 2. When the first support rod 1 or the second support rod 2 is rotated, the detection head component is directly driven to rotate until it reaches the appropriate detection position.

[0046] In this scheme, the auxiliary component is equivalent to providing a stable detection function, that is, if the detector is detected by only relying on the adjustment rod to lift the detection head component, when the strong magnet 305 on the inner side of the elbow 304 is close to the detector position, the distance and strength are not well controlled, and the problem of touching is very likely to occur. In addition, the distance between the strong magnet 305 and the detector is too large, which affects the detection accuracy; and when the staff wants to perform a tentative detection by rotating the position of the strong magnet 305, they directly rotate the first support rod 1 or adjust the rod body without moving it, and realize it by turning the human body in circles. Such rotation is unstable, which is likely to cause The elbow part 304 or the strong magnet 305 collides with the outer shell of the detector; an auxiliary component is added at the position of the second support rod 2, that is, the support ring body 409 is used in conjunction with the auxiliary bearing 402. When it is necessary to rotate the strong magnet 305 for tentative detection, the rotation axis of the regulating rod body is the same as the axis of the auxiliary bearing 402, so that the rotation tentative detection work of the strong magnet 305 is relatively stable; of course, in actual detection work, many more detectors may be required for detection. In order to improve work efficiency and the operating burden of staff, the auxiliary components can also be temporarily removed, and its use is highly flexible.

[0047] During the detection process, for detectors that have been used for a long time, dust and other impurities will adhere to the smoke inlet and magnetic conduction sensing position on them, and corresponding cleaning work is required. On the one hand, it is best to avoid affecting the magnetic induction detection work; on the other hand, it is also best to avoid interference with the subsequent detector's induction of smoke. Therefore, in this solution, a detection cleaning accessory can be set at the position of the cross-shaped carrier plate 301, that is, the installation connection hole body 303 on the cross-shaped carrier plate 301 is connected to the detection cleaning accessory; the detection cleaning accessory includes a limit end 501, a threaded cylinder 502, an internal thread fastening ring body 503, a rotating auxiliary protrusion 504, an extension strip body 505, an arc-shaped carrier plate member 506 and a cleaning soft hair 507; the limit end 501 A threaded cylinder 502 is fixedly provided at one end, and after the threaded cylinder 502 passes through the installation and connection hole body 303, it is threadedly connected to the internal threaded fastening ring body 503, and a rotation auxiliary protrusion 504 is equidistantly arranged in an annular shape on the outer side wall of the internal threaded fastening ring body 503; the threaded cylinder 502 and the installation and connection hole body 303 are provided with the same number of groups, and the end diameter of the threaded cylinder 502 is equal to the width of the slot of the installation and connection hole body 303; an extension strip body 505 is fixedly provided on one side of the limiting end head 501, and an arc-shaped carrier plate member 506 is fixedly provided on the other end of the extension strip body 505, and the inner side wall of the arc-shaped carrier plate member 506 is evenly provided with cleaning soft hairs 507, and the arc-shaped carrier plate member 506 is equidistantly arranged on the cross-shaped carrier plate 301 There are four groups, and the arc-shaped carrier pieces 506 are equidistantly arranged in a ring shape, and the arc-shaped carrier pieces 506 are arranged between adjacent elbow parts 304; that is, for the installation of the detection and cleaning accessories, the threaded cylinder 502 is passed through the installation and connecting hole body 303, so that the limiting end 501 is tightly attached to the cross-shaped carrier plate 301, and at the same time, the position of the arc-shaped carrier piece 506 connected to the side of the limiting end 501 is adjusted so that the position of the arc-shaped carrier piece 506 is between adjacent strong magnets 305, and then the end of the threaded cylinder 502 extending from the installation and connecting hole body 303 is threadedly connected using the internal thread fastening ring body 503, and the internal thread fastening ring body 503 is tightened, and the outer wall of the internal thread fastening ring body 503 is tightened. A rotating auxiliary protrusion 504 is provided to facilitate the loosening and tightening of the internal thread fastening ring body 503, and a cleaning soft bristle 507 is provided on the inner side of the arc-shaped carrier member 506. The arc-shaped carrier member 506 here corresponds to the setting position of the strong magnet 305. The strong magnet 305 is equidistantly arranged in a ring shape. The arc-shaped carrier member 506 in this scheme is also equidistantly arranged in a ring shape, and the rings formed by the two overlap. The purpose is to set the arc-shaped carrier member 506 on the route when the strong magnet 305 is rotated, so that a more accurate cleaning effect can be performed on the magnetic induction position in the detector, which has a positive effect on improving the detection work efficiency; the detection cleaning accessories provided are very helpful for cleaning detectors that have been used for a long time;When testing a relatively new detector, cleaning work is not very meaningful. In order to reduce the burden on the staff, the detection cleaning accessories can be removed, that is, the internal thread fastening ring 503 can be loosened to release the positioning work of the limit end 501, and then the threaded cylinder 502 can be pulled out from the installation connection hole 303, and finally the arc-shaped carrier 506 can be removed. The detection cleaning accessories are also detachable, and can be flexibly disassembled and used according to different usage occasions, and can also provide better convenience for the maintenance and replacement of the arc-shaped carrier 506 and the cleaning soft hair 507. ;
