When repairing the road surface, it is necessary to use enclosure isolation devices to fence the surrounding area of ​​the road surface to prevent pedestrians and vehicles from crossing the damaged road surface when the road surface is not repaired, which brings inconvenience to the maintenance work. The existing isolation devices generally do not have a self-luminous function, and rely more on the light of surrounding street lamps for drivers to see; however, this warning method is not obvious, especially in the middle of the night when the driver is tired, it is easy to knock down the isolation device; at the same time, when the surrounding street lamps are damaged, the loss of street lamp light will further increase the safety hazard. Therefore, it is necessary to add a self-luminous function to the isolation device, and it is also necessary to consider the later disassembly and maintenance issues. Summary of the invention

A sliding block (76) is arranged in the described stroke cavity. The sliding block (76) divides the stroke cavity into a left stroke cavity (741) and a right stroke cavity (742). A right spring (752) is arranged in the right stroke cavity (742). Two ends of the right spring (752) are respectively connected to the sliding block (76) and the right mounting block (72). A left spring (751) is arranged in the left stroke cavity (741). Two ends of the left spring (751) are respectively connected to the sliding block (76) and the left mounting block (71). The elastic force of the right spring (752) is greater than that of the left spring (751) and maintains a tendency to push the sliding block (76) to the left. A locking cross bar (77) is fixedly arranged at the left end of the sliding block (76). The left mounting block (71) is provided with a through hole for the locking cross bar (77) to pass through. After the lamp board (41) is completely inserted into the inner cavity (30), the locking cross bar (77) can extend into the locking groove (4111) of the limiting rod (411) to achieve the purpose of locking the limiting rod (411). A first guide hole (781) communicating with the left stroke cavity (741) is arranged in the left mounting block (71). A first air guide channel (782) connected to the first guide hole (781) is arranged in the inner cavity (30). An interface pipe (783) connected to the first air guide channel (782) is arranged on the right side of the guiding seat (31). Gas is injected into the left stroke cavity (741) through the interface pipe (783) to push the locking cross bar (77) to move rightward to disengage from the locking groove (4111).

7. An isolation device for an asphalt pavement according to claim 6, characterized in that: The cross-sectional shape of the end of the locking cross bar (77) is arc-shaped.

8. The isolation device for asphalt pavement according to claim 1, characterized in that: Two conductive feet (81) are fixedly arranged at the lower end of the lamp board (41). The two conductive feet (81) are arranged at intervals. Two wiring seats (82) are conductively arranged on the circuit board (43). After the lamp board (41) is completely inserted into the inner cavity (30), the two conductive feet (81) can respectively extend into the corresponding two wiring seats (82) to form independent conductive connections. The power supply (44) is welded on the circuit board (43). A placement opening for the power supply (44) to be placed into the inner cavity (30) is arranged on the side of the guiding seat (31). A cover plate (83) is arranged at the placement opening. A single-chip microcomputer (431), a MOS transistor (432) connected to the single-chip microcomputer (431), and a wireless communication module (433) are arranged on the circuit board (43).
