Description

Technical Field

[0001] The present invention relates to the technical field of subsea observation equipment, and particularly to a cordless deployment device for subsea observation equipment. Background Art

[0002] For the observation work of the offshore seabed, it is very important for scientific research, marine environmental protection, fishery production, disaster monitoring and prevention, as well as seabed resource exploration and development. With the rapid development of high technologies, subsea observation equipment has gradually become an important means for humans to understand and manage the ocean.

[0003] Subsea observation equipment is an offshore bottom-mounted ocean monitoring device. When in use, the subsea observation device needs to be deployed using a rope and placed on the seabed at a predetermined position for fixed-point, long-term, and continuous monitoring of the ocean environment. The observation period of the subsea observation equipment is long, and it is necessary to control the subsea observation equipment to release, float, and recover through an acoustic remote control method to obtain monitoring data.

[0004] Since detection instruments are installed on the subsea observation equipment, it is impossible to directly suspend it using a release hook. Therefore, a rope needs to be connected to the subsea observation equipment. When the traditional subsea observation equipment is deployed, the rope cannot be removed and will reach the seabed along with the equipment. Under the action of turbulence and tidal current on the seabed, the rope may be entangled and tied to the subsea observation equipment, resulting in the device being unable to rise from the seabed to the sea surface. In addition, the propellers of passing ships may also entangle the rope of the subsea observation equipment, resulting in damage to the subsea observation equipment. Summary of the Invention

[0005] By providing a cordless deployment device for subsea observation equipment in an embodiment of the present application, the technical problem in the prior art that the rope cannot be removed during the deployment of subsea observation equipment is solved, realizing the cordless deployment of subsea detection equipment and avoiding the situation where the rope entangles the subsea observation equipment.

[0006] To solve the above technical problem, the present invention adopts the following technical solution. A cordless deployment device for subsea observation equipment includes a first shackle and a second shackle installed on the subsea observation equipment. One end of a first main pull rope and at least two second main pull ropes are connected to the first shackle. One end of the first main pull rope far from the first shackle is connected to a release hook through a third shackle. A hook is hung inside the hook head of the release hook. The hook includes a hanging shaft located inside the hook head of the release hook. Hooks are hinged at both ends of the hanging shaft. A hanging rope is connected between the hook and the third shackle. One end of the second main pull rope far from the first shackle passes through a corresponding second shackle and is sleeved on the hook.

[0007] Since one end of the secondary main pull rope far from the first shackle passes through the second shackle of the subsea observation device and is sleeved on the hook, when the hook head of the hook releases the secondary main pull rope, the secondary main pull rope can be disengaged from the second shackle, thus realizing the cordless deployment of the subsea detection device and avoiding the situation of the rope winding around the subsea observation device.

[0008] Further, when the hanging shaft is located within the hook head of the release hook, the hanging rope is in a relaxed state, and the hooks hinged at both ends of the hanging shaft are in a closed state; when the hanging shaft slides out of the hook head of the release hook, the hanging rope is in a tensioned state, and the hooks hinged at both ends of the hanging shaft are in a separated state.

[0009] Further, the length of each secondary main pull rope is greater than twice the length of the primary main pull rope.

[0010] Further, the lengths of all the secondary main pull ropes are equal; this can ensure that when the subsea observation device is released, the secondary main pull ropes can be separated from the second shackles simultaneously, facilitating the deployment.

[0011] Further, a hanging loop is provided at one end of the secondary main pull rope far from the first shackle, and the secondary main pull rope is hung on the hook through the hanging loop; this can facilitate the unhooking of the secondary main pull rope.

[0012] Further, a fifth shackle is provided at the upper end of the hook, and the hanging rope is connected to the corresponding hook through the fifth shackle.

[0013] Further, all the second shackles are installed in an equiangular circumferential array on the upper edge of the subsea observation device; this can ensure that the subsea detection device is in a balanced state before the secondary main pull ropes are separated from the second shackles, facilitating the operation.

[0014] Further, a fourth shackle is also connected to the first shackle, and the first shackle is hooked to the fourth shackle.

[0015] Further, the release hook includes a hanger plate, on which a first linkage and a second linkage are respectively hinged. A cavity for accommodating the hanging shaft is formed between the second linkage and the hanger plate. The first linkage is connected to a pull rope. When the pull rope is pulled, the first linkage can drive the second linkage to rotate and open the cavity. Thus, pulling the pull rope can cause the first linkage to rotate relative to the hanger plate, thereby driving the second linkage to rotate relative to the hanger plate, and further opening the cavity for accommodating the hook.

[0016] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages:

[0017] Since one end of the secondary main pulling rope, which is far from the first shackle, passes through the second shackle of the subsea observation device and is sleeved on the hook, when the hook head of the hook releases the secondary main pulling rope, the secondary main pulling rope can be disengaged from the second shackle, thus realizing the cordless deployment of the subsea detection device and avoiding the situation of the rope winding around the subsea observation device.

Detailed Embodiments

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in this patent, other embodiments obtained by those of ordinary skill in the art without creative efforts all fall within the scope of protection of this patent.

[0025] The present invention discloses a cordless deployment device for a subsea observation device. Please refer to Figures 1 to 4, the cordless deployment device for the subsea observation equipment includes a first shackle 4 and a second shackle 6 installed on the subsea observation equipment 17. A primary main cable 2 and at least two secondary main cables 5 are connected to the first shackle 4. One end of the primary main cable 2 far from the first shackle 4 is connected to a release hook 1 through a third shackle 7. A lifting hook 3 is hung inside the hook head of the release hook 1. The lifting hook 3 includes a hanging shaft 13 located inside the hook head of the release hook 1. Hooks 14 are hinged at both ends of the hanging shaft 13. A hanging rope 16 is connected between the hook 14 and the third shackle 7. One end of the secondary main cable 5 far from the first shackle 4 passes through a corresponding second shackle 6 and is sleeved on the hook 14.

[0026] Among them, since one end of the secondary main cable 5 far from the first shackle 4 passes through the second shackle 6 of the subsea observation equipment 17 and is sleeved on the hook 14, when the hook head of the hook 14 releases the secondary main cable 5, the secondary main cable 5 can be disengaged from the second shackle 6, thus realizing the cordless deployment of the subsea exploration equipment and avoiding the situation of the cable winding around the subsea observation equipment 17.

[0027] Specifically in this embodiment, a fourth shackle 8 is also connected to the first shackle 4, and the first shackle 4 is hooked to the fourth shackle 8. A fifth shackle 15 is provided at the upper end of the hook 14, and the hanging rope 16 is connected to the corresponding hook 14 through the fifth shackle 15. When the hanging shaft 13 is located inside the hook head of the release hook 1, the hanging rope 16 is in a relaxed state, and the hooks 14 hinged at both ends of the hanging shaft 13 are in a closed state; when the hanging shaft 13 slides out of the hook head of the release hook 1, the hanging rope 16 is in a tensioned state, and the hooks 14 hinged at both ends of the hanging shaft 13 are in a separated state.

[0028] More specifically, the release hook 1 includes a hanger plate 9. A first linkage 10 and a second linkage 11 are respectively hinged to the hanger plate 9. A cavity for accommodating the hanging shaft 13 is formed between the second linkage 11 and the hanger plate 9. The first linkage 10 is connected to a pull rope 12. When the pull rope 12 is pulled, the first linkage 10 can drive the second linkage 11 to rotate and open the cavity.

[0029] Since the first linkage 10 is connected to the pull rope 12, pulling the pull rope 12 can realize the rotation of the first linkage 10 relative to the hanger plate 9, thereby driving the second linkage 11 to rotate relative to the hanger plate 9, and then opening the cavity for accommodating the lifting hook 3. It can be understood that when the cavity for accommodating the lifting hook 3 is opened, the hook 14 will fall under the traction of the secondary main cable 5. When the hook 14 falls a certain distance, it will be subjected to the tension of the hanging rope 16, so that the bottom end of the hook 14 opens, and then the disengagement of the secondary main cable 5 from the lifting hook 3 is realized.

[0030] In addition, the release hook 1 can also adopt other existing structures, which will not be elaborated here.

[0031] In this embodiment, please refer to Figure 1 , the lengths of the secondary main guy ropes 5 are all more than twice the length of the primary main guy rope 2, and the lengths of all the secondary main guy ropes 5 are equal. All the second shackles 6 are mounted on the upper edge of the seabed observation device 17 in an equiangular circumferential array. Thereby, it can be ensured that when the seabed observation device 17 is released, the secondary main guy ropes 5 can be separated from the second shackles 6 simultaneously, facilitating the deployment. Specifically, in this embodiment, a hanging ring is provided at one end of the secondary main guy rope 5 far from the first shackle 4, and the secondary main guy rope 5 is hung on the hook 14 through the hanging ring, thereby facilitating the unhooking of the secondary main guy rope 5.
