Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting equipment, and more particularly to the technical field of fire fighting diving and rescue, and in particular to a combined search tool for multiple underwater search and rescue modes. Background Art

[0002] Fire rescue forces mainly use circular search and rescue methods, fan-shaped search and rescue methods, and rail-type search and rescue methods for underwater search and rescue. When using the above three methods for underwater search and rescue, it is necessary to first divide the water area to be searched into several areas, and then set up an anchor point to use this as a base point for the search. Due to the complex underwater conditions, dim light, and poor visibility, divers cannot distinguish directions well underwater, and auxiliary tools are needed to help divers distinguish directions and search within the effective area. Currently, floating ropes are generally used as auxiliary tools for underwater searches.

[0003] When using a floating rope for underwater search and rescue, the floating rope will play two roles. One is an anchor point, which serves as a mark of the starting point. A float is fixed on the top of the rope and a weight is tied to the bottom. The floating rope can be straightened so that the rope is perpendicular to the water surface, and firefighters can search around the anchor point. The other is a guide rope, one end of which is tied to the anchor point and can move up and down according to different water depths. The other end is tied to the diver, and the diver searches within a certain range according to the length of the guide rope.

[0004] However, there are still some disadvantages when it is used in operations, such as:

[0005] 1. When using a floating rope, the floating rope is flexible and not easy to straighten. At the same time, when the water flow speed is too fast, the floating rope will bend and deviate as an anchor point, causing deviations in the starting point and range of the search.

[0006] 2. When firefighters are searching underwater, the floating rope that serves as a guide rope will also bend, causing deviations in the search coverage area.

[0007] 3. During diving and swimming, the guide rope can easily get entangled with the diver's hands and feet, or debris in the water, posing a life-threatening hazard to the diver.

[0008] 4. The floating rope is troublesome to organize and store before and after use. If you are not careful, it will become tangled and entangled, making it impossible to quickly carry out rescue work.

[0009] 5. After being used underwater, the floating rope needs to be dried, which takes a long time. It is easy to rot and break after a period of use.

[0010] 6. It is easy to wear and break when it hits stones or sharp objects

[0011] Therefore, we propose a combined search tool for multiple underwater search and rescue modes to solve the problems raised above. Summary of the invention

[0047] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 There are three groups of middle mounting holes 8 arranged at equal intervals in the middle part of the mast 1, and the mounting holes 8 are through-hole structures, and the mounting holes 8 are correspondingly plugged and connected with the limit pins 9 for the convenience of limiting.

[0050] Working principle: When using this combined search tool for multiple underwater search and rescue modes, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 In the present solution, a docking groove 3 is provided at the end of the mast 1. Through the docking joint 2 fixed at the top of the mast 1, the docking joint 2 can be plugged into the docking groove 3 accordingly, so that the mast 1 monomers can be connected end to end to be lengthened. At the same time, the inner side of the docking joint 2 is connected with a ball 5 through a spring 6.
