[0028] Embodiment 1

[0029] See also Figures 1 to 6 , a highway construction safety isolator, comprising a first base and a second base, characterized in that: the first base and the second base are symmetrically arranged, the first base and the second base are both fixedly connected in the convex grooves opened on the surfaces of the first base and the second base, the surface of the first slide bar is slidably sleeved with a convex block, the convex blocks are respectively slidably connected to the first base and the second base, the convex blocks are respectively fixedly connected to the first base and the second base with a second spring, the surfaces of the two convex blocks are fixedly connected with an isolation fence, a fixed fence is fixedly connected between the first base and the second base, a damping rod and a first spring are equidistantly fixedly connected between the isolation fence and the fixed fence, and the first spring is sleeved on the surface of the damping rod.

[0030] A mounting groove is provided on one side of the first base and the second base that is close to each other, and a wedge block is arranged in the mounting groove, and the wedge block is fixedly connected to the first base and the second base respectively; a rectangular plate is fixedly sleeved on the surface of the isolation fence at the upper position of the wedge block, an alarm is fixedly installed on the surface of the rectangular plate, a first conductive block is fixedly connected to the bottom surface of the rectangular plate, a T-bar is slidably connected to the bottom surface of the isolation fence, the T-bar and the wedge block are slidably connected, and a third spring is fixedly connected between the T-bar and the isolation fence.

[0031] The top cap of the T-shaped rod is made of metal conductive material, and the T-shaped rod, the first conductive block and the alarm are connected in series through a wire.

[0032] A fixing plate is fixedly sleeved on the surface of the isolation fence, and reflective strips are fixedly connected with the surface of the fixing plate at equal intervals.

[0033] The working principle of this embodiment: when using this type of safety isolator, first transfer the isolator to the construction position of the highway and fix the position of the isolator. During use, when a vehicle hits the isolation fence, the isolation fence will slide on the surfaces of the first base and the second base due to the impact force. The movement of the isolation fence will then squeeze the damping rod and the first spring. The cooperation of the damping rod and the first spring can buffer the impact force generated when the isolation fence is hit, and to a certain extent, the damage to the isolation fence caused by the impact force can be reduced. When the impact force of the vehicle is large, the isolation fence moves backward. During this process, the T-bar follows the movement, so that the T-bar can slide on the surface of the wedge block. When the damping rod is compressed to the shortest position, the T-bar just moves to the smooth position on the surface of the wedge block. At this time, the T-bar slides upward, so that the first conductive block and the T-bar are in contact. At this time, the circuit of the alarm is connected, and the alarm starts to sound an alarm, thereby prompting construction workers at a distance to stop construction and reminding construction workers to deal with the accident site in time, which can ensure the personal safety of construction workers in the construction area to a certain extent.

[0034] It should be noted that a battery box (not shown) is provided on the surface of the fixed column, and batteries are installed in the battery box. The T-shaped rod and the first conductive block are connected to the positive and negative electrodes of the battery through wires respectively.

[0035] By setting up reflective strips, it is convenient to remind passing vehicles and reduce the probability of accidents.
