Description
Technical Field
[0001] The utility model relates to the technical field of underwater object salvage, and specifically relates to an offshore salvage hook. Background Art
[0002] At present, the salvage hooks used on scientific research ships are usually simple "J"-shaped hooks. When using these hooks to salvage scientific research equipment and instruments on the sea surface, as long as there are slight waves on the sea, it is very difficult for offshore scientific research operators to hook the "J"-shaped hook onto the lifting point of the equipment to be salvaged. The success rate of hooking is low. Also, due to the simple structure and no anti-unhooking device, even if the hook is successfully hooked onto the lifting point of the equipment to be salvaged, it is very easy to unhook, which affects the work efficiency of offshore scientific research operations. Content of the Utility Model
[0003] Aiming at the deficiencies in the prior art, the utility model provides an offshore salvage hook, which can improve the success rate during the process of hooking scientific research equipment and instruments at sea and prevent the hooked scientific research equipment / instruments from unhooking.
[0004] To achieve the above object, the utility model provides an offshore salvage hook, which is characterized in that it includes a body. The body has a first frame and a second frame that are symmetric about the center. Structural bases are respectively provided at the bottoms of the first frame and the second frame. Two locking catches are respectively hinged to the two structural bases. Arc-shaped support blocks are respectively provided inside the two locking catches. The two arc-shaped support blocks are respectively connected to the body through elastic ropes. A closed area is formed between the two arc-shaped support blocks and the two elastic ropes. Salvage guiding openings are respectively provided outside the two locking catches. An acute angle is formed between the salvage guiding opening and the locking catch.
[0005] For the offshore salvage hook as described above, further, adjustable weights are provided on the two locking catches.
[0006] For the offshore salvage hook as described above, further, the end of the locking catch can be seated in the pit of the structural base.
[0007] For the offshore salvage hook as described above, further, it further includes a hook and an acoustic-optic indicating dynamometer. One end of the acoustic-optic indicating dynamometer is connected to the body, and the other end is connected to the hook.
[0008] For the offshore salvage hook as described above, further, the acoustic-optic indicating dynamometer includes a spring and an internal circuit. One end of the spring is connected to the body, and the other end is connected to the hook. The internal circuit includes a retractable wire, a brush, and a conductive slide rail. The spring is linked to the retractable wire, the retractable wire is linked to the brush, and the brush slides on the conductive slide rail.
[0009] The above-mentioned marine salvage hook. Further, the internal circuit further includes a battery, a dynamometer switch, a yellow warning sound and light buzzer, a red alarm sound and light buzzer, and a green operation indicator light. The battery is used to supply power to the internal circuit. The dynamometer switch is used to turn on or cut off the sound and light indication of the dynamometer. The carbon brush slides on the conductive slide rail, thereby changing the resistance value in the internal circuit, and then triggering the yellow warning sound and light buzzer, the red alarm sound and light buzzer, and the green operation indicator light.
[0010] The above-mentioned marine salvage hook. Further, two sets of internal circuits are provided.
[0011] The above-mentioned marine salvage hook. Further, the angle between the salvage guiding port and the latch is 30°.
[0012] The above-mentioned marine salvage hook. Further, the main body and the latch are made of a stainless steel bar with a diameter of 16 mm, and the structural base is made of a 40-mm thick stainless steel plate.
[0013] The above-mentioned marine salvage hook. Further, the hook is also provided with a hook spring piece.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] 1. The end of the latch has an adjustable weight block, and the sensitivity of the latch trigger can be adjusted by configuring the weight of the weight block.
[0016] 2. A device salvage guiding port is also designed below the latch, thereby greatly improving the success rate in the process of salvaging the hook of marine scientific research instrument equipment.
[0017] 3. Since the latch adopts a split design and there are two arc-shaped support blocks on the inner side, after the device salvage point enters the closed area composed of the arc-shaped support blocks and the elastic rope through the guiding port, the device is no longer as easy to unhook as the traditional "J"-type hook.
[0018] 4. A sound and light indication dynamometer is designed at the hook above the salvage hook, which has the functions of green, yellow, and red sound and light indication / alarm, is safe and reliable, is convenient to maintain, and is convenient for scientific research operation personnel to intuitively judge whether the marine scientific research instrument equipment to be salvaged is overweight or overloaded, so as to avoid unnecessary safety operation risks.

[0026] See Figures 1 to 6 , this embodiment provides a marine salvage hook, including a body 3. The body 3 has a first frame and a second frame that are symmetric about the center. Structural bases 10 are respectively provided at the bottoms of the first frame and the second frame. Locking latches 8 are respectively hinged to the two structural bases 10. Arc-shaped support blocks 5 are respectively provided inside the two locking latches 8. The two arc-shaped support blocks 5 are respectively connected to the body 3 through elastic ropes 4. A closed area is formed between the two arc-shaped support blocks 5 and the two elastic ropes 4. Salvage guiding openings 9 are respectively provided outside the two locking latches 8. An acute angle is formed between the salvage guiding opening 9 and the locking latch 8.
[0027] Specifically, when it is necessary to salvage scientific research equipment / instruments, the marine salvage hook of this embodiment is gradually moved above the suspension point of the scientific research equipment / instruments. At this time, the side of the locking latch 8 closer to the center of the marine salvage hook is heavier than the side farther from the center, and the two locking latches 8 are horizontally arranged. Preferably, the structural base 10 is provided with a concave pit, and the end of the locking latch 8 can be seated in the concave pit of the structural base 10. Then, when the marine salvage hook is gradually moved towards the scientific research equipment / instruments, with the guiding function of the salvage guiding opening 9, the suspension point of the scientific research equipment / instruments is smoothly guided to the center of the marine salvage hook, thereby improving the success rate during the process of salvaging and hooking the scientific research instrument and equipment in the sea. Preferably, the angle between the salvage guiding opening 9 and the locking latch 8 is 30°. Then, the suspension point of the scientific research equipment / instruments pushes open the side of the two locking latches 8 closer to the center of the marine salvage hook. The two locking latches 8 rotate upward with the pin shaft 6 as the "lever" fulcrum. Then, when the suspension point of the scientific research equipment / instruments enters the closed area formed between the two arc-shaped support blocks 5 and the two elastic ropes 4, the two locking latches 8 rotate downward with the pin shaft 6 as the "lever" fulcrum until they are horizontally arranged, and further lock the suspension point of the scientific research equipment / instruments in this closed area. The end of the locking latch 8 is seated in the concave pit of the structural base 10 to ensure the stability of the locking latch 8 when bearing the gravity of the equipment, so that the hooked scientific research equipment / instruments are not easily unhooked.
[0028] As an alternative implementation, in some embodiments, the two latches 8 are provided with adjustable weights 7, and the sensitivity of the latch 8 triggering can be flexibly adjusted by adjusting their weights to meet different salvage requirements.
[0029] As an alternative implementation, in some embodiments, the marine salvage hook of this embodiment further includes a hook 1 and an acoustic-optic indicating dynamometer 2. One end of the acoustic-optic indicating dynamometer 2 is connected to the body 3, and the other end of the acoustic-optic indicating dynamometer 2 is connected to the hook 1. Through the display of the acoustic-optic indicating dynamometer 2, the load status during the salvage process can be monitored and indicated in real time, facilitating the scientific research operators to intuitively judge whether the scientific research instruments / equipment to be salvaged at sea are overweight or overloaded, so as to avoid unnecessary safety operation risks.
[0030] In the above embodiment, further, the acoustic-optic indicating dynamometer 2 includes a spring 18 and an internal circuit. One end of the spring 18 is connected to the body 3, and the other end of the spring 18 is connected to the hook 1. The internal circuit includes a retractable wire 15, a brush 19, and a conductive slide rail 20. The spring 18 is linked to the retractable wire 15, the retractable wire 15 is linked to the brush 19, and the brush 19 slides on the conductive slide rail 20. Specifically, through the linkage of the spring 18 and the retractable wire 15, the mechanical tension is converted into an electrical signal to drive the brush 19 to slide on the conductive slide rail 20, realizing the real-time monitoring and feedback of the load.
[0031] In the above embodiments, the internal circuit further includes a battery 17, a dynamometer switch 16, a yellow warning sound and light buzzer 13, a red alarm sound and light buzzer 12, and a green operation indicator light 14. The battery 17 is used to supply power to the internal circuit. The dynamometer switch 16 is used to turn on or cut off the operation of the sound and light indicating dynamometer 2. The brush 19 slides on the conductive slide rail 20, thereby changing the resistance value in the internal circuit, and then triggering the yellow warning sound and light buzzer 13, the red alarm sound and light buzzer 12, and the green operation indicator light 14. Exemplarily, the green operation indicator light 14: continuously lights up when the load is below 90% of the rated load, indicating that the current working state is safe and normal. The yellow warning sound and light buzzer 13: when the load reaches 90% but does not exceed 100% of the rated load, the yellow buzzer will emit sound and light warnings to remind the operator to pay attention and may need to adjust the operation or prepare countermeasures. The red alarm sound and light buzzer 12: once the load reaches or exceeds 100% of the rated load, the red buzzer immediately starts sound and light alarms. This is an emergency signal, requiring the operator to immediately stop the operation to prevent overloading accidents. The use of a sound and light dual warning method ensures that warning information can be effectively conveyed under different environmental conditions (such as noisy, poor visibility, etc.), improving the operation safety. It is equipped with a 24V replaceable battery 17, which is convenient for long-term use and later maintenance. At the same time, the sound and light indication function can be easily turned off through the dynamometer switch 16 to adapt to different usage scenarios and energy-saving requirements.
[0032] In the above embodiments, two sets of internal circuits are provided. Specifically, the internal circuit design adopts a left-right symmetric and mutually independent dual-system, which not only improves the reliability of the equipment but also allows for backup each other when necessary, ensuring that it will not be affected by a single failure during critical moments.
[0033] As an alternative embodiment, in some embodiments, the body 3 and the latch 8 are made of a 16mm diameter stainless steel bar, the structural base 10 is made of a 40mm thick stainless steel plate, and the first frame and the second frame are strengthened as shown in Figure 5 the figure.
[0034] As an alternative embodiment, in some embodiments, the hook 1 is further provided with a hook spring piece 11. The hook spring piece 11 can firmly fix the lifted heavy object, prevent the heavy object from slipping or falling during lifting, and can also effectively prevent the hook from rotating during lifting.
