[0025] Two fixing components are arranged on the fixed base plate 1, which are used to fix the fixed base plate 1 on the required land. The fixing components include two arc-shaped sliding sleeves 2. The two arc-shaped sliding sleeves 2 are welded and fixed on the upper surface of the fixed base plate 1. The two arc-shaped sliding sleeves 2 are arc-shaped in appearance.

The two curved sleeves 2 are arranged in a staggered manner in a scissor-like manner, which enables the first curved plate 3 and the second curved plate 14 to penetrate downward into the ground at an inclined angle and in an arc-shaped moving trajectory, and after penetrating the ground, the lower ends of the first curved plate 3 and the second curved plate 14 move outward and open, so that the oblique pointed heads 13 at the lower ends of the first curved plate 3 and the second curved plate 14 can be firmly fixed in the ground, making the protective enclosure body 15 not easy to tip over.

[0027] Furthermore, the lower ends of the first arc plate 3 and the second arc plate 14 are integrally formed with an oblique tip 13 , and the opposite sides of the two arc-shaped sliding sleeves 2 are fixedly connected with gear fixings 7 , and a rotating shaft 8 is rotatably connected between the two gear fixings 7 .

[0028] Furthermore, a pinion gear 9 is fixedly sleeved on the outer surface of the rotating shaft 8 , and one end of the rotating shaft 8 rotates and passes through the outer surface of the one side gear fixed 7 , and a worm gear 10 is fixedly sleeved.

[0029] Furthermore, a meshing groove 5 is milled on one side of the two arc-shaped sliding sleeves 2 close to the pinion 9 , and the meshing groove 5 is located at the position where the first arc-shaped plate 3 and the second arc-shaped plate 14 intersect and overlap.

[0030] Furthermore, teeth 6 are provided on one side of the first arc plate 3 and the second arc plate 14 close to the pinion 9, and the two teeth 6 are respectively located at the upper end of the first arc plate 3 and the second arc plate 14. The two teeth 6 are meshed with the pinion 9 through the meshing groove 5.

[0031] Furthermore, a motor 11 is fixedly connected to the upper surface of the fixed base plate 1 by bolts, a worm 12 is fixedly sleeved on the outer surface of the output shaft of the motor 11 , and the worm 12 is meshingly connected to the worm wheel 10 .

[0032] Furthermore, when in use, the construction safety protection fence is placed at the position where it needs to be installed and fixed, and the operator or other heavy objects press on the fixed base plate 1 to start the motor 11. The output shaft of the motor 11 drives the worm wheel 10 to rotate through the worm 12 thereon, and the rotating worm wheel 10 drives the pinion 9 to rotate through the rotating shaft 8 thereon. When the pinion 9 rotates, it can drive the first arc plate 3 and the second arc plate 14 to move downward along the trajectory of the arc sleeve 2 through the teeth 6, so that the first arc plate 3 and the second arc plate 14 can penetrate the ground downward at an inclined angle and an arc-shaped moving trajectory, and after penetrating the ground, the lower ends of the first arc plate 3 and the second arc plate 14 move outward and open, so that the oblique pointed heads 13 at the lower ends of the first arc plate 3 and the second arc plate 14 can firmly hook the soil, fixing the fixed base plate 1 firmly underground, making the protection enclosure body 15 more difficult to tip over, and also improving the wind resistance of the protection enclosure body 15 to a certain extent.

[0033] Furthermore, the self-locking and deceleration properties of the worm wheel 10 and the worm 12 enable the shaft 8 to rotate with a large torque, and the pinion 9 is smaller in diameter than the worm wheel 10 and also has a certain deceleration property, so that the torque transmitted to the two teeth 6 by the pinion 9 after being acted upon by the rotating shaft 8 can be further increased, so that the inclined tip 13 at the lower end of the first arc plate 3 and the second arc plate 14 can have enough force to penetrate the soil. This fixing method is easier than the traditional method of fixing by hammering ground nails, and the fixed base plate 1 is also convenient enough when disassembling. Only the motor 11 needs to be started to reverse, and the first arc plate 3 and the second arc plate 14 can be retracted, so that the safety protection fence for construction has great convenience, so that the fence can be flexibly adjusted according to changes in the construction progress to adapt to different construction needs. At the same time, after the project is completed, the fence can also be easily disassembled and stored for reuse in future projects, thereby realizing effective utilization of resources.

[0034] Working principle: when in use, the construction safety protection fence is placed at the position where it needs to be installed and fixed, and the operator or other heavy objects press on the fixed base plate 1, and the motor 11 is started. The output shaft of the motor 11 drives the worm wheel 10 to rotate through the worm 12 thereon, and the rotating worm wheel 10 drives the pinion 9 to rotate through the rotating shaft 8 thereon. When the pinion 9 rotates, it can drive the first arc plate 3 and the second arc plate 14 to move downward along the trajectory of the arc sleeve 2 through the teeth 6, so that the first arc plate 3 and the second arc plate 14 can penetrate the ground downward at an inclined angle and an arc-shaped moving trajectory, and after penetrating the ground, the lower ends of the first arc plate 3 and the second arc plate 14 move outward and open, so that the oblique pointed heads 13 at the lower ends of the first arc plate 3 and the second arc plate 14 can firmly hook the soil, and the fixed base plate 1 is firmly fixed underground, so that the protective enclosure body 15 is more difficult to tip over;

[0035] The self-locking and deceleration properties of the worm wheel 10 and the worm 12 enable the shaft 8 to rotate with a large torque, and the pinion 9 is smaller in diameter than the worm wheel 10 and also has a certain deceleration property, so that the torque transmitted to the two teeth 6 by the pinion 9 after being acted upon by the rotation of the shaft 8 can be further increased, so that the inclined tips 13 at the lower ends of the first arc plate 3 and the second arc plate 14 can have enough force to penetrate the soil. This fixing method is easier than the traditional method of fixing with ground nails, and the fixed base plate 1 is also convenient enough when disassembling. Only by starting the motor 11 to reverse, the first arc plate 3 and the second arc plate 14 can be retracted, making the safety protection fence for construction very convenient.
