Technical Field

[0001] The utility model relates to the technical field of fire protection zone evaluation, in particular to a safety evaluation device for fire protection zones in a pipe gallery. Background Art

[0002] A pipe gallery is an infrastructure used to accommodate various pipelines. It is usually built underground in cities or in underground spaces in specific areas. For example, in order to effectively control the spread of fire and protect the safety of people and property when a fire occurs, the pipe gallery will be divided into several areas according to certain fire protection requirements, and each fire compartment of the pipe gallery will be equipped with a safety evaluation device. The safety evaluation device is a comprehensive safety system that integrates multiple functions such as fire detection, video surveillance, gas detection, and structural monitoring to achieve comprehensive monitoring and evaluation of the fire compartments of the pipe gallery.

[0003] However, the existing safety evaluation devices for fire protection in pipe corridors are generally exposed to the air in the pipe corridors without any protective measures. When a fire occurs in the pipe corridor, the safety evaluation devices cannot be protected and are likely to be burned, resulting in the loss of internal data, which makes it inconvenient for subsequent investigations into the cause of the accident.

[0004] In order to solve this technical problem, the utility model proposes a safety evaluation device for fire protection zones in pipe corridors. Utility Model Content

[0005] The main purpose of the utility model is to provide a safety evaluation device for fire protection zones in a pipe gallery, which can effectively solve the problems mentioned in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A safety evaluation device for fire partitioning of a pipe gallery comprises a shell, a protective cover is arranged at a side end of the shell, a track groove is connected inside the shell, a fire curtain is slidably connected inside the track groove, a transverse threaded rod is rotatably connected to the upper and lower ends of the track groove, a threaded block is connected to the upper and lower ends of the fire curtain, a connecting block is connected to the side end of the shell, a connecting rod is rotatably connected inside the connecting block, a No. 1 motor is arranged at the side end of the shell, a backup battery is connected to the side end of the shell, an evaluation device is arranged inside the shell, and the evaluation device includes a variety of detection equipment.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, a fire curtain is provided, and the No. 1 motor is started to drive the connecting rod and the transverse threaded rod to rotate. The threaded rod and the threaded block work together to move the fire curtain in the track groove, so as to close the evaluation device. This can prevent dust from entering the evaluation device when the device is not in use, and avoid damage to the evaluation device caused by bumps during transportation. When a fire occurs in the tunnel, the evaluation device can be protected (the power supply in the tunnel may be cut off when a fire occurs, and the backup battery can power the device to complete the closure of the fire curtain), avoiding the loss of data due to burning, and facilitating subsequent investigations into the cause of the accident. This solves the problem of the existing safety evaluation device for fire protection in the tunnel, which has no protective measures. When a fire occurs in the tunnel, the safety evaluation device is likely to be burned, resulting in the loss of internal data, which makes it inconvenient to conduct subsequent investigations into the cause of the accident.

[0016] In the utility model, a suction fan is provided, which sucks in external air and then inputs it into the air duct through the air deflector. The air duct is discharged from the air outlet pipe at the side end to blow air to the evaluation device. The No. 2 motor is started to drive the vertical threaded rod to rotate. The vertical threaded rod and the threaded ring act to drive the air duct to move up and down, thereby cleaning off the dust on various detection equipment in the evaluation device, which can effectively prevent the dust from interfering with the detection equipment.
