DETAILED DESCRIPTION
[0029] The utility model will be described in detail below in combination with Figures 1 to 5 The utility model will be described in detail below in combination with
[0030] The utility model provides a kind of auxiliary searching system for salvage at sea, as shown in Figures 1 to 3 It further includes a collecting device 30 arranged on the anchor boat 10, and the output end of the collecting device 30 is connected with a cable assembly 20; the cable assembly 20 is detachably connected with a positioning device 40 at the end away from the anchor boat 10; the positioning device 40 includes a first claw hook 50, and a second claw hook 60 fixed on both sides of the first claw hook 50 respectively, and the top end of the first claw hook 50 or the second claw hook 60 is provided with a connecting part 401 connected with the cable assembly 20. During operation, the positioning device 40 is used to preliminarily position the large component on the seabed, and then the personnel of the related equipment are uniformly arranged to carry out salvage, so as to improve the salvage efficiency and save the cost. The combination of the first claw hook 50 and the second claw hook 60 can quickly grasp the target object, reduce the operation time, and has strong grasping force, so as to adapt to large components of different shapes and ensure that the large components will not fall off during the searching and positioning process.
[0031] In this embodiment, as shown in Figure 4 and Figure 5 The first claw hook 50 includes a first hook body 501, and the end of the first hook body 501 away from the connecting part 401 extends a first hook part 502; the second claw hook 60 includes a second hook body 601, and the end of the second hook body 601 away from the connecting part 401 extends a second hook part 602, and the installation direction of the first hook part 502 and the second hook part 602 is opposite, forming a grasping space with an opening facing the connecting part 401, so that the positioning device 40 can smoothly embed the large component when it is dragged in the seabed environment.
[0032] In this embodiment, the second claw hook 60 is welded on both sides of the first claw hook 50, and the welding seam completely fills the gap of the connecting part, so that the welding seam is completely integrated with the first claw hook 50 and the second claw hook 60, uniformly distributes stress, improves the connection strength, and ensures that the first claw hook 50 and the second claw hook 60 will not separate during the salvage process. Specifically, the first claw hook 50 and the second claw hook 60 are cut from a 2cm-thick steel plate, and the height of the welding seam between the first claw hook 50 and the second claw hook 60 is equal to the height of the second hook body 601, so as to ensure that the connection between the first claw hook 50 and the second claw hook 60 is stable enough.
[0033] In this embodiment, the first hook portion 502 is formed with a first pointed end 503 at one end away from the first hook body 501, and the second hook portion 602 is formed with a second pointed end 603 at one end away from the first hook body 501, so that when the large component is covered by silt, sand or seaweed, the positioning device 40 can penetrate these coverings through the first pointed end 503 and the second pointed end 603, directly grab the large component, and provide stronger grabbing force for the positioning device 40 to prevent the positioning device 40 from slipping off the large component. The axes of the first pointed end 503 and the second pointed end 603 are arranged to deviate from the axis of the first hook body 501, and specifically, the first pointed end 503 and the second pointed end 603 are arranged to face away from the first hook body 501, so that the radial dimension of the grabbing space formed by the first hook portion 502 and the second hook portion 602 at the opening is maximized, and the large component can be better grabbed.
[0034] In this embodiment, the top of the first hook portion 502 extends a connecting portion 401, which is a connecting plate extending in the axial direction at the top end of the first claw hook 50. The connecting plate is provided with a connecting hole 402, which is connected with the cable assembly 20. The connecting hole 402 can also be used to connect with a towing device such as a shackle. Further, the height of the second hook body 601 is lower than the height of the first hook body 501. Further, the second hook portion 602 is the same in size as the first hook portion 502, and the horizontal heights of the two ends of the first hook portion 502 and the second hook portion 602 are not equal. Specifically, the highest horizontal height of the first pointed end 503 is higher than the horizontal height at the connection between the first hook body 501 and the first hook portion 502, and the highest horizontal height of the second pointed end 603 is higher than the horizontal height at the connection between the second hook body 601 and the second hook portion 602, so as to prevent the large component from slipping after being grabbed.
[0035] In this embodiment, the two second claw hooks 60 are symmetrically distributed around the first claw hook 50. The two sides of the first hook body 501 are symmetrically fixed with a second claw hook 60 respectively, and the included angle between the second claw hook 60 and the first claw hook 50 is 120 degrees, so that a stable triangular support can be formed when the object is grabbed, the distribution force is more uniform, the object is prevented from tilting or slipping, and thus the grabbing efficiency is improved. In some embodiments, the number of second claw hooks 60 can be set according to actual needs, and each second claw hook 60 is uniformly distributed on the two sides of the first hook body 501. Specifically, the height of the first claw hook 50 is 60 cm, the width is 40 cm, the height of the first hook body 501 is 45 cm, the thickness is 2 cm, the height of the second claw hook 60 is 35 cm, the height of the second hook body 601 is 25 cm, and the width and thickness of the second claw hook 60 are the same as those of the first claw hook 50.
[0036] In the embodiment, the collecting device 30 is a winch, which can provide power for the winding and unwinding of the cable assembly 20. The cable assembly 20 is a steel wire rope with a shackle fixed at one end. One end of the steel wire rope is connected with the winch, and the other end is fixed with the connecting hole 402 of the positioning device 40 through the shackle.
[0037] During the salvage search, the positioning device 40 is connected with the winch on the anchor boat 10 through the steel wire rope to form a search system. The connecting hole 402 of the first claw hook 50 is detachably connected with a shackle. The steel wire rope is connected with the shackle. The positioning device 40 can be wound and unwound through the height adjustment of the steel wire rope. The anchor boat 10 drags the positioning device 40 to travel at a uniform speed in a designated large sea area. When the positioning device 40 in the sea hooks the large member object on the seabed, the positioning is realized by moving the anchor boat 10 above the large member object through the recovery winch or in the direction of the steel wire rope. After the coordinate point is recorded, the salvage is carried out by uniformly collecting ship equipment and personnel in the later period, the efficiency is improved, and the cost is saved.
