Problems solved by technology
However, due to the requirements of not changing the shape of the dropped object, not affecting its underwater trajectory and landing point, and limited by the volume of the dropped object itself, the released ropes are often thinner, and may be trapped in underwater mud when falling to the bottom. , if it is directly recovered by pulling a thinner rope, the rope will break due to insufficient strength and the recovery will fail

Embodiment Construction
[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0017] as attached figure 1 As shown, the present invention provides a grapple for underwater recovery of objects, the recovery grapple 7 includes a hook body 1, a counterweight 2, a limit pin 3, a pin shaft 4 and a recovery rope 5, and the peripheral equipment is a thin rope 8;
[0018] One end of the hook body 1 is a hook-shaped structure, and the other end is processed with a connection hole for connecting the recovery rope 5;
[0019] as attached figure 2 As shown, one end of the counterweight 2 is processed into a lug structure, and the end of the hook body 1 with a connecting hole can be embedded in the gap formed by the lug; two through holes are processed on the lug, and one through hole is a limit pin hole , the other through hole is a connecting pin hole; a through hole is processed on the part below the lug on the counterweight 2, and the ax...

The invention discloses a grapple for underwater recycling of objects, and belongs to the technical field of underwater recycling device structures. The recovery grapple includes a hook body, a counterweight and a recovery rope. The peripheral equipment is a thin rope; the hook body is fixedly connected with the recovery rope, the counterweight is connected to the straight handle section of the hook body, and the recovery grapple passes through the The coordinating through hole of the grapple and the string are guided to sink into the water, and the counterweight quality of the counterweight ensures that the overall center of mass of the grapple is located below the string, so that the hook body is always above the string when the recovery grapple is lowered freely. The present invention can be lowered along the thin rope connected with the underwater throwing object, and the thick rope can be used to replace the thin rope by grasping the underwater throwing object, so as to realize the reliable recovery of the underwater throwing object.
Description
technical field [0001] The invention relates to an underwater recovery device, in particular to an underwater recovery grapple for throwing objects, and belongs to the structural technical field of underwater recovery devices. Background technique [0002] To realize the complete recovery of the objects thrown into the water, the most direct way is for the diver to go into the water and tie a recovery rope with sufficient strength. However, when the water depth is deep, divers have difficulty diving down. Therefore, a feasible recovery method is that after the object is put into the water and falls to the bottom, it can release the floating body itself, pull out the rope connected to it, and then manually pull the object out of the water surface by means of a winch to realize recovery. However, due to the requirements of not changing the shape of the dropped object, not affecting its underwater trajectory and landing point, and limited by the volume of the dropped object it...
