[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-7 , the present utility model provides the following technical solutions: An intelligent and precise safety alarm for construction sites.

[0027] Embodiment 1: In order to solve the problem that during construction at a construction site, a large amount of dust will float, and as a result, a large amount of dust will adhere to the surface position of the reminder, which is not conducive to reminding construction workers, reference can be made to the attached Figure 1 - attached Figure 7, an air storage mechanism is arranged at the internal position of the fixed pipe 4. The air storage mechanism can move the scraping strips 18 at both sides of the surface of the protective shell 7, so that the scraping strips 18 can clean the display screen installed inside the protective shell 7; A group of reciprocating lead screws 51 are also fixed at the middle position of the rotating rod 5. The outer side of the reciprocating lead screw 51 is at the central position inside the fixed pipe 4, and the height of the reciprocating lead screw 51 is one-fourth of the height of the fixed pipe 4; The air storage mechanism includes a threaded sleeve 11 threadedly connected to the outer side of the reciprocating lead screw 51. The bottom end of the threaded sleeve 11 is fixed to the top of the piston block 12. The outer side of the piston block 12 is attached to the square groove 13 opened on the inner side of the fixed pipe 4. An air inlet 14 is opened at the bottom position of the rotating rod 5. The outer end of the air inlet 14 is connected to the bottom end position of the air delivery pipe 15. The top end of the air delivery pipe 15 extends out from the upper end of the rotating rod 5, and the other end of the air delivery pipe 15 extends into the protective shell 7. The outer end of the air delivery pipe 15 is connected to the bottom end position of the telescopic member 16. The top end position of the telescopic member 16 is fixed to the bottom of the moving block 17. The inner sides of the two moving blocks 17 are fixed to the outer ends of the scraping strips 18. A plurality of jet ports 19 are opened at the side of the scraping strip 18 close to the protective shell 7; The inner wall of the square groove 13 and the outer wall of the piston block 12 are mutually attached, and a one-way intake valve is arranged at the lower position of the square groove 13. A one-way exhaust valve is arranged inside the air delivery pipe 15; The telescopic member 16 includes a telescopic rod 161 fixed to the bottom of both sides of the protective shell 7. A moving rod 162 is slidably arranged inside the upper end of the telescopic rod 161. A conical block 163 is attached to the inner side of the bottom of the moving rod 162. The top of the conical block 163 is connected to the inside of the moving rod 162 through a return spring 164; The inside of the moving rod 162 is communicated with the through holes between the moving block 17 and the scraping strip 18. The through holes are communicated with the jet ports 19. The elastic force of the return spring 164 and the gravity of the scraping strip 18.

[0028] By starting the fixed motor 2, when the rotating rod 5 rotates, it will also drive the reciprocating lead screw 51 to rotate. As a result, the threaded sleeve 11 threadedly connected to the inner side of the reciprocating lead screw 51 can drive the piston block 12 to move in position. Then, the piston block 12 slides in the square groove 13 opened inside the fixed pipe 4, squeezing and pushing the gas below the square groove 13. Thus, the gas flows into the inside of the rotating rod 5 through the air inlet 14, and then can be transported through the air delivery pipe 15. When the inside of the air delivery pipe 15 is filled with gas, the gas will drive the moving rod 162 to move inside the telescopic rod 161. Then, the top position of the moving rod 162 drives the moving block 17 and the scraping strip 18 to slide on one side of the protective shell 7, and the scraping strip 18 cleans the display panel of the protective shell 7. When the scraping strip 18 moves to the maximum position, the tapered block 163 will squeeze one side of the return spring 164, making the return spring 164 in an open state. Then, the gas jets through the jet port 19 to clean the brush of the scraping strip 18. Through the above settings, the display panel inside the protective shell 7 can be cleaned, and it is convenient to display cases of non-standard construction.

[0030] First, when using this safety alarm, by pushing the moving base 1, the moving base 1 moves stably on the ground and then moves to the designated position, so as to monitor the designated construction site. And by starting the fixed motor 2, the output end of the fixed motor 2 can drive the rotating rod 5 to rotate inside the fixed pipe 4. Then, the fixed pipe 4 can drive the protective shell 7 to rotate, and the monitor body 9 at the bottom of the protective shell 7 can rotate, so as to monitor in multiple directions. The image signals collected by the monitor body 9 are converted into electrical signals, and are judged by the sensors inside the protective shell 7. When the construction is not standard, the alarm device body 8 will give an alarm.
