[0025] Pins 4 are provided at the four corners of the upper surface of the fixing seat 5. The bottom ends of the pins 4 penetrate the fixing seat 5 and extend to the lower part of the fixing seat 5. The fixing seat 5 can be fixed to the ground through the pins 4, further improving the stability of the protective device during use, effectively preventing the protective device from tipping over or tilting due to external force, thereby avoiding affecting the normal use of the protective device.

[0026] An expansion mechanism 2 is provided on the back of the fixed frame 1, and the expansion mechanism 2 includes a dual-output shaft servo motor 205 fixed on the back of the fixed frame 1, and a baffle 10 is fixedly connected to the back of the two support plates 202. Two stabilizing plates 7 are fixedly connected to the outer surface of the dual-output shaft servo motor 205. The baffle 10 is used to shield the expansion mechanism 2, which effectively prevents foreign objects from colliding with the expansion mechanism 2 during use and causing damage to the expansion mechanism 2, thereby avoiding affecting the normal use of the protective device.

[0027] The dual-output shaft servo motor 205 is a servo motor with two output shafts, which refers to an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control the speed and has very accurate position accuracy. It can convert the voltage signal into torque and speed to drive the control object. The servo motor rotor speed is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

[0028] The two output shafts of the dual-output shaft servo motor 205 are fixedly connected with threaded rods 209, and the back of the fixed frame 1 is fixedly connected with two support plates 202. The two threaded rods 209 are rotatably connected to the two support plates 202 at one end away from the dual-output shaft servo motor 205, and the outer surface of each threaded rod 209 is threadedly connected with a screw ring 2010, and the outer surface of each screw ring 2010 is fixedly connected with two movable plates 206.

[0029] Two sliding rods 203 are fixedly connected to one side of the two support plates 202 that are close to each other, and two sliding rings 204 are slidably connected to the outer surface of each sliding rod 203. The ends of the two groups of movable plates 206 away from the screw ring 2010 are fixedly connected to the outer surfaces of the two groups of sliding rings 204 respectively. During the movement of the movable plates 206, the sliding rings 204 can be driven to slide on the outer surfaces of the sliding rods 203, so that the movable plates 206 can move along the direction of the sliding rods 203, effectively improving the stability of the movable plates 206 during the movement, and effectively preventing the movable plates 206 from being deflected and stuck during the movement.

[0033] The front sides of the two sets of movable rods 2011 are fixedly connected to the back sides of the two expansion plates 201 respectively. The front sides of the movable rods 2011 pass through the through slots 207 and extend to the interior of the fixed frame 1. The movable rods 2011 have no contact with the inner walls of the through slots 207, which can effectively avoid friction between the movable rods 2011 and the through slots 207 during movement, thereby avoiding wear on the outer surfaces of the movable rods 2011 due to long-term use, thereby affecting the normal use of the movable rods 2011 due to the wear of the movable rods 2011.

[0034] A construction warning board 6 is fixedly connected to the front of the fixed frame 1, and a warning message is written on the front of the construction warning board 6. The warning message on the construction warning board 6 can warn passers-by that construction is going on ahead and there are safety hazards, so they can take a detour in time.

[0035] The warning words on the construction warning board 6 can be replaced according to the needs of the users, so as to conveniently display different warning purposes.

[0036] When in use, first place the protective device on the ground and fix the fixing seat 5 with the pins 4, then the dual-output shaft servo motor 205 drives the two threaded rods 209 to rotate, the threaded rod 209 drives the screw ring 2010 to move, the screw ring 2010 drives the movable plate 206 to move, the movable plate 206 drives the expansion plate 201 to move through the movable rod 2011, and the movable rod 2011 drives the two expansion plates 201 to extend from the inside of the fixed frame 1, thereby increasing the overall protection area of ​​the protective device.
