Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5 As shown, a construction safety device for preventing falling objects from heights includes a mounting frame 101. A vertical rod 102 is fixedly connected to the bottom of the mounting frame 101. Several mounting holes are provided on the mounting frame 101 and the vertical rod 102. The mounting frame 101 and the vertical rod 102 are fixed to the exterior wall of the building or the scaffolding through the mounting holes. A protective net 2 is fixedly connected between the mounting frames 101 to protect against falling mud or other objects and prevent injuries caused by falling objects from heights. A collection box 3 is bolted between the mounting frames 101. The collection box 3 is detachable to facilitate the cleaning of the items collected in the collection box 3. The collection box 3 is located at the end of the protective net 2 and below the protective net 2 to facilitate the movement of items on the protective net 2 into the collection box 3. A traction rope 201 is connected between the collection box 3 and the end of the protective net 2 to fix the end of the protective net 2 and improve the stability of the protective net 2.

[0026] A driving mechanism is provided below the protective net 2. The driving mechanism includes two first vertical plates 401 bolted to the bottom of the mounting frame 101. The two first vertical plates 401 are distributed at both ends of the bottom of the mounting frame 101. A lead screw 402 is rotatably connected between the two first vertical plates 401. Two second vertical plates 403 are also bolted to the bottom of the mounting frame 101. A sliding rod 404 is fixedly connected between the two second vertical plates 403. A movable plate 405 is threaded onto the lead screw 402. The movable plate 405 is slidably connected to the sliding rod 404. A driving plate 406 is fixedly connected to the top of the movable plate 405. The top of the driving plate 406 abuts against the bottom of the protective net 2. The top of the driving plate 406 is arc-shaped to avoid damage to the protective net 2.

[0027] A reinforcing rod 103 is fixedly connected between the vertical rod 102 and a first vertical plate 401 located away from the vertical rod 102. A reinforcing rod 103 is also fixedly connected between the vertical rod 102 and a second vertical plate 403 located away from the vertical rod 102. The two reinforcing rods 103 are arranged one after the other to improve the stability of the mounting frame 101.

[0028] The mounting bracket 101 is also equipped with a power assembly, which is used to drive the lead screw 402 to rotate. The power assembly includes a driven gear 501. The end of the lead screw 402 extends out of the first vertical plate 401 and is fixedly connected to the driven gear 501. Two mounting plates 502 are bolted to the front side of the mounting bracket 101. A rotating shaft 503 is rotatably connected between the two mounting plates 502. A driving gear 504 is fixedly connected to the rotating shaft 503. The driving gear 504 meshes with the driven gear 501. The end of the rotating shaft 503 extends out of the mounting plate 502 and is fixedly connected to a rocker arm 505. Rotating the rocker arm 505 drives the rotating shaft 503 to drive the driving gear 504 to rotate. The driving gear 504 meshes with the driven gear 501, thereby driving the driven gear 501 to drive the lead screw 402 to rotate. The lead screw 402 drives the moving plate 405 to drive the driving plate 406 to move along the bottom of the protective net 2.

[0029] Working principle: In use, the mounting frame 101 and the vertical rod 102 are fixed to the exterior wall of the building or the work scaffold. The protective net 2 protects against falling mud or other objects, preventing injuries from falling objects. When an object falls onto the protective net 2, it will cause the net 2 to fall. When a worker notices an object on the protective net 2, he turns the rocker arm 505. The rocker arm 505 drives the rotating shaft 503, which in turn drives the drive gear 504. The drive gear 504 meshes with the driven gear 501, thereby driving the driven gear 501 to drive the lead screw 402 to rotate. The lead screw 402 drives the moving plate 405 to rotate. The moving plate 406 moves along the bottom of the protective net 2. Since the protective net 2 will fall down where the item falls, the item is located at a relatively low position. Therefore, as the moving plate 406 moves along the bottom of the protective net 2, it will drive the fallen item to gradually roll towards the collection box 3. After the item reaches the end of the protective net 2, it will gradually fall into the collection box 3, making it easier to clean and collect the debris that has fallen on the protective net 2 and ensure the service life of the protective net 2. Then, the rocker arm 505 is reversed, so that the lead screw 402 drives the moving plate 405 to move the moving plate 406 away from the collection box 3 and gradually reset.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
