[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-8 As shown, a smart construction site installation protection device includes a detector body 1, a support base 4 fixedly connected to the bottom end of the detector body 1, a docking rod 6 fixedly connected to the bottom end of the support base 4, the bottom outer wall of the docking rod 6 is frustoconical, a support sleeve 5 is slidably sleeved on the bottom outer wall of the docking rod 6, and a protection mechanism for automatically protecting and deprotecting the detector body 1 is provided on the docking rod 6. The protective mechanism includes: an annular sliding plate 204 that is slidably sleeved on the outer wall of the docking rod 6; an annular airbag 206 that is fixedly connected to the bottom end of the annular sliding plate 204; a first limiting collar 205 that is slidably sleeved on the outer wall of the annular sliding plate 204; the annular airbag 206 that is located inside the first limiting collar 205; an air supply pipe that is fixedly connected to the outer wall of the annular airbag 206; the air supply pipe that extends to the outside of the first limiting collar 205; and the end of the air supply pipe that is away from the annular airbag 206 that is fixedly connected to the output end of the air pump through a multi-port connector. The support sleeve 5 is provided with a fixing mechanism for docking and fixing with the docking rod 6.

[0027] In this embodiment, it is important to note that the working principle of the detector body 1 is to identify and quantify the dust concentration by means of the interaction between dust and the detection signal. The mainstream methods include light scattering method (dust scatters light, and the signal intensity is correlated with the concentration), β-ray absorption method (dust adsorbs the filter membrane and absorbs the rays, and the concentration is calculated by the attenuation), and weighing method (the concentration is converted by weighing the filter membrane after it adsorbs dust). Their common logic is to first collect a dusty air sample, and then convert it into an electrical signal by the interaction of a specific signal generated by the detection element with the dust. After amplification and calibration, the dust concentration value or an alarm signal exceeding the standard is output. In use, push the docking rod 6 to slide into the inside of the support sleeve 5 until the docking rod 6 contacts the bottom of the inner wall of the support sleeve 5. At this time, the support sleeve 5 and the docking rod 6 can be conveniently docked and locked by the fixing mechanism. When it is necessary to disassemble, maintain or replace the detector body 1, the above operation is reversed to achieve the purpose of convenient disassembly of the docking rod 6. When it is necessary to detect dust in the surrounding environment through the detector body 1, the side protection of the detector body 1 can be removed through the protective mechanism to facilitate dust detection operation in the surrounding environment through the detector body 1. When the detector body 1 is no longer in use or when the side of the detector body 1 is protected, the above operation is reversed to protect the side of the detector body 1. In this way, the top and side of the detector body 1 can be protected respectively during use, effectively preventing bird droppings, falling stones and splashes from damaging the detector body 1.

[0028] In one embodiment, such as Figures 1-7 As shown, the protective mechanism also includes: a first protective component disposed on the support base 4; The first protective component includes: multiple fixed sleeves 207 circumferentially and equidistantly fixedly connected to the outer wall of the support base 4; a connecting rotating frame 208 is slidably sleeved on the outer wall of each of the multiple fixed sleeves 207; and a protective rotating frame 209 is fixedly connected to the end of the connecting rotating frame 208 away from the support base 4. The annular sliding plate 204 is provided with a second protective component for shielding and protecting the top of the detector body 1; The fixed sleeve 207 is provided with a transmission component for driving the fixed sleeve 207 to rotate; The second protective component includes: multiple connecting slide rods 202 circumferentially and equidistantly fixed to the outer wall of the annular slide plate 204; the multiple connecting slide rods 202 intersect with multiple fixed sleeves 207; the multiple connecting slide rods 202 are all L-shaped; a straight sliding groove for the connecting slide rods 202 to slide is provided at the position where the first limiting sleeve 205 connects with the connecting slide rods 202; a protective top cover 201 is provided on the top of the detector body 1; the multiple connecting slide rods 202 are all located at the bottom of the protective top cover 201; the protective top cover 201 is fixedly connected to the multiple connecting slide rods 202; through the cooperation of the first protective component and the second protective component, the top and sides of the detector body 1 can be protected respectively, effectively preventing bird droppings, falling gravel and splashes from damaging the detector body 1.

[0029] In one embodiment, such as Figures 1-7 As shown, the transmission assembly includes: a gear 2011 rotatably connected inside the fixed sleeve 207; two connecting shafts 2010 are symmetrically fixedly connected to the outer wall of the gear 2011; the two connecting shafts 2010 pass through the fixed sleeve 207 and are fixedly connected to the connecting rotating frame 208; the connecting shafts 2010 are rotatably connected to the fixed sleeve 207; a rack 203 is meshed with the outer wall of the gear 2011; the rack 203 passes through the fixed sleeve 207 and is fixedly connected to the annular slide plate 204; the rack 203 is slidably connected to the fixed sleeve 207. Through the mutual cooperation of the gear 2011 and the rack 203, multiple protective rotating frames 209 can be synchronously rotated during the lifting and lowering of the annular slide plate 204.

[0030] In one embodiment, such as Figures 1-8 As shown, the fixing mechanism includes: a docking assembly disposed on the support sleeve 5; The docking assembly includes: a second docking ring 308 fixedly connected to the top of the support sleeve 5, the second docking ring 308 slidably sleeved on the outer wall of the docking rod 6, a first docking ring 303 provided on the upper surface of the second docking ring 308, the first docking ring 303 fixedly connected to the outer wall of the docking rod 6, the first docking ring 303 located at the bottom of the annular airbag 206, the first docking ring 303 fixedly connected to the annular airbag 206, a second limiting collar 301 fixedly connected to the outer wall of the first docking ring 303, the second limiting collar 301 slidably sleeved on the outer wall of the second docking ring 308, and the second limiting collar 301 fixedly connected to the first limiting collar 205; The second docking ring 308 is provided with a locking component for engaging and limiting the first docking ring 303; The second docking ring 308 is provided with a positioning component for engaging and positioning the second limiting collar 301; The second limiting collar 301 is provided with a locking component for locking and fixing the second limiting collar 301; The engaging assembly includes: multiple fixed shafts 306 circumferentially and equidistantly fixedly connected to the top of the second docking ring 308; each fixed shaft 306 has a limiting plug 305 fixedly connected to its top; the outer wall of the top of the limiting plug 305 is frustoconical; an arc-shaped groove 304 is provided at the junction of the first docking ring 303 with the limiting plug 305 and the fixed shafts 306 for sliding; and a docking slot 302 is provided at the end of the first docking ring 303 located away from the limiting plug 305 in the arc-shaped groove 304 for sliding of the fixed shaft 306. Through the cooperation of the docking assembly and the engaging assembly, convenient limiting docking of the first docking ring 303 and the second docking ring 308 can be achieved.

[0031] In one embodiment, such as Figures 2-8 As shown, the positioning assembly includes: two limiting baffles 3010 symmetrically slidably connected inside the second docking ring 308; a docking rod 6 located between the two limiting baffles 3010; a positioning block 3011 fixedly connected to the end of each of the two limiting baffles 3010 away from the docking rod 6; the outer wall of the end of the positioning block 3011 away from the limiting baffle 3010 is hemispherical; the positioning block 3011 penetrates through the second docking ring 308 to the inside of the second limiting collar 301; and the positioning block 3011 is slidably connected to the second docking ring 308. A reset component is provided on the limiting baffle 3010; the reset component includes a spring 309 disposed at the end of the limiting baffle 3010 away from the positioning block 3011, one end of the spring 309 is in contact with the outer wall of the limiting baffle 3010, and the other end of the spring 309 is in contact with the inner wall of the second docking ring 308. Through the cooperation of the positioning component and the reset component, the automatic engagement and positioning of the first docking ring 303 and the second docking ring 308 can be realized.

[0032] In one embodiment, such as Figures 1-6 As shown, the locking assembly includes a knurled bolt 307 disposed on the outside of the second limiting collar 301. The knurled bolt 307 is located between the two limiting baffles 3010. The knurled bolt 307 passes through the second limiting collar 301 to the inside of the second mating ring 308. The knurled bolt 307 is threadedly connected to the second mating ring 308. The second limiting collar 301 and the second mating ring 308 can be locked and fixed by the knurled bolt 307.

[0033] The above embodiment discloses a smart construction site installation protection device. In use, the docking rod 6 is pushed and slidably inserted into the inside of the support sleeve 5 until the docking rod 6 contacts the bottom end of the inner wall of the support sleeve 5. At this time, the first docking ring 303, driven by the docking rod 6, contacts the upper surface of the second docking ring 308 and slides onto the limiting block 305 through the docking slot 302. At the same time, the second limiting sleeve 301, driven by the first docking ring 303, slides onto the outer wall of the second docking ring 308, thereby realizing convenient docking between the first docking ring 303 and the second docking ring 308. During this process, the positioning block 3011, under the pressure of the inner wall of the second limiting sleeve 301, pushes the limiting baffle 3010 to slide along the inner wall of the second docking ring 308. At this time, the limiting baffle 3010 is contracted by the moving compression spring 309. Then, the docking rod 6 rotates along the inner wall of the support sleeve 5 and the second docking ring 308. At this time, the second limiting ring 301 rotates synchronously under the drive of the docking rod 6 through the first docking ring 303. At the same time, the docking slot 302 and the arc-shaped slide 304 rotate synchronously under the drive of the first docking ring 303. This allows the limiting block 305 and the fixed shaft 306 to slide along the inner wall of the arc-shaped slide 304. When the limiting block 305, the fixed shaft 306 and the arc-shaped slide 304 move away from the docking slot 308, When the inner walls of one end of 02 come into contact, the spring 309 pushes the limiting baffle 3010 through rebound, causing the positioning block 3011 to be inserted into the interior of the second limiting collar 301. This allows the second limiting collar 301 to be engaged and positioned. Then, the knurled bolt 307 is rotated to thread through the second limiting collar 301 and the second docking ring 308, thereby achieving the locking and fixing of the second limiting collar 301 and the second docking ring 308. This allows for convenient docking and locking of the support sleeve 5 and the docking rod 6. When it is necessary to disassemble, maintain or replace the detector body 1, the above operation is reversed to achieve the purpose of convenient disassembly of the docking rod 6. When dust detection of the surrounding environment is required through the detector body 1, the air pump is started to inflate the annular airbag 206 through the multi-port connector and air supply pipe. This allows the annular airbag 206 to expand. At this time, the annular slide plate 204 slides and rises along the outer wall of the docking rod 6 under the push of the expansion of the annular airbag 206. At the same time, the protective top cover 201 rises synchronously under the drive of the annular slide plate 204 through multiple connecting slide rods 202. At this time, multiple racks 203 move synchronously under the push of the annular slide plate 204. At the same time, the gear 2011 drives the connecting rotating frame 208 to rotate through the connecting rotating shaft 2010 under the meshing drive of the racks 203. At this time, the protective rotating frame 209 rotates synchronously under the drive of the connecting rotating frame 208, so as to release the side protection of the detector body 1 and perform dust detection operation of the surrounding environment through the detector body 1. When the detector body 1 is no longer in use or when the side of the detector body 1 is protected, the above operation is reversed. The side of the detector body 1 can be protected by the protective rotating frame 209. In this way, during use, the top and side of the detector body 1 can be protected by the protective top cover 201 and the protective rotating frame 209 respectively, effectively preventing bird droppings, falling gravel and splashes from damaging the detector body 1.
