[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please see Figures 1-5 This application provides a smart monitoring and early warning device for preventing falls during high-altitude operations, including a main support 1, with auxiliary supports 2 on both sides of the main support 1, and each auxiliary support 2 is provided with a variable length component between it and the main support 1 to adjust the distance between the main support 1 and the auxiliary support 2. Each auxiliary support 2 is also provided with a blowing component.

[0029] The blower assembly includes a fixed base 9 mounted on the secondary support 2. A rotating shaft 12 is rotatably connected to the fixed base 9. A fan base 15 is fixedly connected to the rotating shaft 12. Multiple fans 16 are arranged side by side at equal intervals on the fan base 15. It should be noted that the fans 16 are powered by an external power supply. It should also be noted that a comprehensive box is mounted on the main support 1. The power connectors of the fans 16 are installed inside the comprehensive box. A rotation drive assembly is mounted on the fixed base 9 for adjusting the angle of the fans 16 on the fan base 15.

[0030] Specifically, this device is placed on the edge of a high-altitude work platform, especially on unprotected high-rise buildings. Using the variable length component, the two auxiliary supports 2 are adjusted to a suitable position to completely cover the dangerous area where falls are likely. When it senses that someone is approaching, the fan 16 blows air to make the worker feel cold, thereby warning the worker not to approach the area further to avoid the risk of falling.

[0031] Furthermore, a storage box 17 is provided on the main support 1. It should be noted that the storage box 17 can be stored inside the monitor 19 when it is not in use, to avoid damage to the monitor 19 during transportation. A stop block 21 is provided on the bottom of the storage box 17 to limit the closing angle of the box door 20. The box door 20 is hinged to the storage box 17 and is equipped with a lock to lock it together with the storage box 17 to prevent the box door 20 from shaking. The monitor 19 is installed on the inside of the box door 20 through the mounting base 18. It should be noted that the monitor 19 is a device with a communication function, and the monitoring screen of the monitor 19 is transmitted to the monitoring equipment in the monitoring room via electrical signals for unified real-time viewing and management by security personnel. When personnel on a certain floor approach a dangerous area where they are prone to falling, security personnel use the monitor 19 on that floor to warn staff to stay away.

[0032] Furthermore, the top of the storage box 17 is provided with a threaded sleeve 22, and the inner side of the threaded sleeve 22 is threaded with a bolt 23, and two limiting rings 24 are fixedly connected to the bolt 23, preferably by welding. A plug 26 is also sleeved on the bolt 23, located between the two limiting rings 24. The top surface of the box door 20 is provided with a connecting frame 25 with an L-shaped cross section. A slot 27 that matches the shape and size of the plug 26 is opened in the center of the top surface of the connecting frame 25 for the plug 26 to be inserted.

[0033] Specifically, after the cabinet door 20 is opened from the storage box 17, the rotating bolt 23 causes it to move downward relative to the threaded sleeve 22. After being limited by two limiting rings 24, the insert block 26 moves downward. Then, the insert block 26 is aligned with the slot 27 and inserted through it. After the insert block 26 is inserted into the slot 27, the connecting bracket 25 is subjected to a lateral restraining force, preventing the cabinet door 20 from rotating relative to the storage box 17, thus supporting the cabinet door 20 and providing support for the monitor 19 on the cabinet door 20. If it is necessary to store the monitor 19 inside the storage box 17, the bolt 23 is rotated in the opposite direction, thereby driving the insert block 26 out of the slot 27. The connecting bracket 25 loses its restraining force, allowing the cabinet door 20 to rotate relative to the storage box 17 and store the monitor 19 inside the storage box 17.

[0034] Furthermore, the rotary drive assembly includes a motor base 8 mounted on a fixed base 9, a servo motor 13 mounted on the motor base 8, a drive gear 10 mounted on the output end of the servo motor 13, a driven gear 11 meshing with the drive gear 10, and the driven gear 11 fixedly connected to the top of the rotating shaft 12.

[0035] Specifically, the servo motor 13 drives the drive gear 10 to rotate, and through the driven gear 11, it drives the rotating shaft 12 to rotate. The rotating shaft 12 can drive the fan base 15 to rotate, thereby adjusting the angle of the fan 16 blowing air.

[0036] Furthermore, the variable length component includes a front connecting rod 5 and a back connecting rod 6, and the front connecting rod 5 and the back connecting rod 6 are arranged in an alternating manner. The front connecting rod 5 includes a first connecting rod 51, a second connecting rod 52 and a third connecting rod 53, and the back connecting rod 6 includes a fourth connecting rod 61, a fifth connecting rod 62 and a sixth connecting rod 63.

[0037] Furthermore, both the main support 1 and the auxiliary support 2 are equipped with a first hinge seat 3 and a second hinge seat 4;

[0038] One end of the first connecting rod 51 is hinged to the second hinge seat 4, and is located on the main support 1. The other end of the first connecting rod 51 is hinged to the fifth connecting rod 62. The end of the fifth connecting rod 62 away from the first connecting rod 51 is hinged to the third connecting rod 53. The end of the third connecting rod 53 away from the fifth connecting rod 62 is hinged to the first hinge seat 3, and is located on the auxiliary support 2.

[0039] One end of the fourth connecting rod 61 is hinged to the first hinge seat 3, and is located on the main support 1. The other end of the fourth connecting rod 61 is hinged to the second connecting rod 52. The end of the second connecting rod 52 away from the fourth connecting rod 61 is hinged to the sixth connecting rod 63. The end of the sixth connecting rod 63 away from the second connecting rod 52 is hinged to the second hinge seat 4, and is located on the auxiliary support 2. It should be noted that multiple sets of the second connecting rod 52 and the fifth connecting rod 62 can be provided.

[0040] Specifically, by pulling the sub-support 2 outward, the intersecting front connecting rod 5 and back connecting rod 6 can be extended, thereby adjusting the width of the device according to the width of the danger zone and covering the danger zone where falls are likely to occur.

[0041] Furthermore, the fixed base 9 is also provided with a protective cover 14, which covers the outside of the driving gear 10, the driven gear 11 and the servo motor 13, and plays a protective role. The protective cover 14 can optionally be provided with heat dissipation channels to provide a heat dissipation environment for the servo motor 13.

[0042] Furthermore, each of the aforementioned front connecting rods 5 is equipped with several equally spaced distance sensors to sense the position of personnel. The integrated box contains a processing controller. The servo motor 13, fan 16, and colored light 28 are electrically connected to the processing controller and the distance sensors, respectively. This is existing technology and is only applicable to this application. That is, when one or more distance sensors detect that a person has entered the danger zone, they will transmit the signal to the processing controller. The processing controller will then control the start of the servo motor 13, fan 16, and colored light 28. The start of the servo motor 13, through transmission, can drive the fan 16 on the fan base 15 to turn towards the person who has mistakenly entered the danger zone. When the fan 16 and colored light 28 are powered on, the fan 16 blows air, and the colored light 28 emits colored light to warn the person to stay away through touch and sight.

[0043] Furthermore, both the main support 1 and the secondary support 2 are provided with a base 29 at their bottom. The base 29 has mounting holes 30 and is fixed to the ground, which serves to restrict the main support 1 and the secondary support 2, forming a guardrail as a barrier.

[0044] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
