DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 and Figure 6 A multifunctional fire-fighting equipment detection device includes a detection mechanism 1 for detecting fire-fighting equipment, wherein the detection mechanism 1 is composed of a sealed cover 101, a smoke generator 104, a first smoke pipe 102 and a second smoke pipe 103 which are telescopically connected, and the first smoke pipe 102 and the second smoke pipe 103 are fixedly connected to the sealed cover 101 and the smoke generator 104 at one end thereof. The output end of the smoke generator 104 is connected to the second smoke pipe 103. The smoke generator 104 can spray smoke to detect the induction of the smoke sensor. It should be noted that the smoke generator 104 is a conventional device known to the public in the prior art, so its specific structural composition and working principle will not be described in detail in this article.

[0039] Specifically, Figure 6As shown, the interiors of the first smoke conveying pipe 102 and the second smoke conveying pipe 103 are both hollow, and the upper and lower ends thereof are connected, and the sealing cover body 101 is trumpet-shaped. The smoke conveying channel of the second smoke conveying pipe 103 is set from wide to narrow. It has many benefits such as improving smoke detection efficiency, optimizing detection performance, reducing maintenance costs and improving safety. For example, when smoke enters a channel from wide to narrow, the flow rate of the smoke will naturally increase due to the reduction in the cross-sectional area of ​​the channel. This acceleration effect helps the smoke to reach the detection area faster, thereby improving the detection efficiency. In a wider channel, the smoke may diffuse or generate eddies due to factors such as air flow and temperature differences, and these phenomena may interfere with the normal operation of the smoke detector. The channel design from wide to narrow helps to reduce these interference factors and improve detection performance.

[0040] In order to facilitate the user to hold the detection mechanism 1, in this embodiment, Figure 1 and Figure 3 As shown, a connecting column 105 is installed at one end of the smoke generator 104 away from the second smoke delivery pipe 103 through bolts, and a handle 106 is detachably installed on the outside of the connecting column 105. The handle 106 consists of a cross bar 1061, a threaded column 1062 and an anti-skid sleeve 1063. The threaded column 1062 is welded to one end of the cross bar 1061 and is connected to the inner thread of the connecting column 105. The cross bar 1061 is installed and fixed by the threaded match between the threaded column 1062 and the connecting column 105, and the anti-skid sleeve 1063 is sleeved on the outer surface of the cross bar 1061. The anti-skid sleeve 1063 is made of rubber, and the outer surface of the anti-skid sleeve 1063 is provided with a plurality of anti-skid protrusions to increase the grip. The setting of the handle 106 allows the user to better hold the detection mechanism 1 for detection work, and the anti-skid sleeve 1063 can increase the grip and prevent slipping.

[0041] In order to improve the smoke detection efficiency of fire fighting equipment, in this embodiment, Figure 1 and Figure 2 As shown, the first smoke delivery pipe 102 and the second smoke delivery pipe 103 are provided with a smoke control device 2, which includes a first circular plate 201, a second circular plate 202, a smoke volume adjustment plate 203, a vertical rod 205, a transmission gear 206 and teeth 207; the number of teeth 207 is equidistantly installed outside the vertical rod 205, and the vertical rod 205 is meshed with the transmission gear 206 through the teeth 207, and a rotating shaft 204 rotatably connected to the inner wall of the second smoke delivery pipe 103 is installed on the opposite side of the smoke volume adjustment plate 203, and one of the rotating shafts 204 extends to the outside of the second smoke delivery pipe 103 and is connected to the transmission gear 206. A sealing gasket is sleeved on the outer surface of the smoke volume adjustment plate 203. A sealing ring is provided at the connection between the rotating shaft 204 extending to the outside of the second smoke delivery pipe 103 and the second smoke delivery pipe 103.

One end of the vertical rod 205 is connected to the outer surface of the first circular disk 201, and the other end of the vertical rod 205 runs through the interior of the two second circular disks 202. A reset spring 208 surrounding the outer surface of the vertical rod 205 is fixedly installed between the first circular disk 201 and the second circular disk 202 at the bottom, so as to better adjust the length of the first smoke conveying pipe 102 and the second smoke conveying pipe 103. An observation window is installed on the second smoke conveying pipe 103, and a transparent glass is embedded in the observation window for observing the amount of smoke. The reset spring 208 is connected to the first circular disk 201 and the second circular disk 202 at the bottom through a connecting plate and a bolt, so as to facilitate the subsequent disassembly of the first smoke conveying pipe 102 and the second smoke conveying pipe 103.

[0043] In this embodiment, two limit locking buckles 209 are installed on the outer surface of the vertical rod 205 close to the two second circular plates 202, which are used to control the extension length of the first smoke delivery pipe 102 and the second smoke delivery pipe 103. When this embodiment is in use, the first smoke delivery pipe 102 and the second smoke delivery pipe 103 are contracted by squeezing the sealing cover 101, and the vertical rod 205 moves through the teeth 207 to mesh with the transmission gear 206 to drive the smoke volume adjustment plate 203 to flip, so that the rotation angle and speed of the smoke volume adjustment plate 203 can be accurately controlled, thereby realizing accurate adjustment of the smoke delivery volume.

[0044] It should be noted that by adjusting the position and angle of the smoke volume adjusting plate 203, the diffusion path of the smoke can be optimized so that the smoke can be more evenly distributed in the test area. The retractable first smoke pipe 102 and the second smoke pipe 103 and the smoke volume adjusting plate 203 are designed to facilitate the maintenance and inspection of the equipment. When cleaning or replacement of parts is required, the relevant components can be easily disassembled and installed. At the same time, this design also helps to reduce wear and failure caused by long-term use and extend the service life of the equipment.

[0045] In addition, the flip design of the smoke volume regulating plate 203 can reduce the direct impact of smoke on the test environment during the smoke delivery process, thereby reducing interference with the test results.

[0049] When the present embodiment is in use, three suction cups 303 arranged in a triangular shape are used to adjust the spacing by cooperating with the lifting sleeve 304 to move up and down, and are fixed by the locking ring 306. The elastic telescopic arm 302 can be extended and retracted according to the flatness of the wall surface, so that the sealing cover body 101 can better dock with the smoke sensor. After the suction cup 303 is in contact with the wall surface, a sealing plug is inserted to perform vacuum, and the suction cup 303 is adsorbed on the wall surface to achieve fixation of the detection mechanism 1, so that the detection mechanism 1 is fixed on the wall surface for long-term detection of the smoke sensor.

[0050] In order to improve the functionality of the detection mechanism 1, in this embodiment, as Figures 6 to 9As shown, a cleaning mechanism 4 is installed at one end of the second smoke duct 103 close to the first smoke duct 102, and the cleaning mechanism 4 includes a shell 401, a scraper block 402 arranged outside the shell 401, a slide rod 403 slidably arranged in the shell 401 and fixedly connected to the scraper block 402, and a driving structure 404 arranged inside the shell 401 to drive the slide rod 403 to move.
