Description

Technical Field

[0001] The utility model relates to the field of emergency rescue, in particular to an amphibious leakage detector. Background Art

[0002] In the prior art, the water and land leakage location search and rescue control box is used as an emergency device for leakage detection and location positioning. However, the existing equipment has certain limitations in water and land applications and cannot meet specific needs. The functions of the existing leakage detector are relatively simple. For example, no protective measures are taken for the safety of rescuers. When rescuers perform rescue operations alone outdoors, their personal safety cannot be guaranteed.

[0003] The Chinese patent with publication number CN217213089U discloses a water and land leakage location search and rescue control box, which is used to realize leakage detection and location positioning.

The motion state of the rescuer is obtained through the motion sensing module. When the motion state of the rescuer is abnormal, an SOS distress signal is sent to call for rescue, so as to solve the problem that the personal safety of the rescuer cannot be guaranteed when performing rescue operations alone.
