Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of marine engineering equipment, and in particular relates to an instrument and equipment deployment and retrieval device applied to the stern of a ship. Background Technology
[0002] In marine scientific research activities, it is usually necessary to use ships to transport survey instruments, sampling devices, and other equipment to the target location in the ocean. These instruments and equipment are then precisely deployed at the target depth or location to carry out scientific research operations. After the scientific research operations are completed, these instruments and equipment must be retrieved back to the ship.
[0003] Conventional ships typically deploy instruments and equipment at sea using winches and A-frames to lift them, then lower them to the target depth or location, and retrieve them from the ocean. However, because ships sway with the waves, the lifted instruments and equipment also sway, increasing the risk of collision and damage. Utility Model Content
[0004] The purpose of this invention is to provide an instrument and equipment deployment and retraction device for use at the stern of a ship, in order to solve the technical problems described in the background art.
[0005] An instrument and equipment deployment and retrieval device for use at the stern of a ship includes:
[0006] The slipway extends to the stern of the ship. A winch is installed at one end of the slipway, and the winch winds up a rope. The other end of the slipway is an opening leading to the outside of the ship. The slipway is inclined downward with the opening as the lowest point.
[0007] The sea-drop box has an open structure and is equipped with detachable instruments and equipment. These instruments and equipment are used for launching into the sea, and the outer end of the pull rope is fixedly connected to the sea-drop box.
[0008] When it is necessary to deploy instruments and equipment into the sea for work, the winch is used to release the pull rope to a specific length, so that the drop box can slide into the stern of the ship through the slide and slide out of the ship from the opening and fall into the sea, causing the drop box to take in water, and the instruments and equipment will also be in the sea. At this time, the instruments and equipment are detached from the drop box.
[0009] When retrieving instruments and equipment operating at sea to the ship, the instruments and equipment are secured in a drop box at sea, and a winch is used to pull up the rope to retrieve the drop box to the ship.
[0010] Based on the above technical solution, the present invention achieves the following beneficial effects:
[0011] 1. Because the instruments and equipment are placed in the drop box during the journey into the sea and when they are retrieved from the ship, the instruments and equipment are prevented from being damaged by direct collision with the ship.
[0012] 2. When the instruments and equipment are deployed into the sea, the winch releases the rope to a specific length, allowing the deployment box to slide into the sea along the slide. At the same time, when the instruments and equipment are retrieved from the sea onto the ship, the winch is used to retract the rope to pull the deployment box back onto the ship from the slide. Therefore, it is not necessary to lift the instruments and equipment when deploying them into the sea or when retrieving them from the sea, thus avoiding the need for a large amount of manpower to stabilize the instruments and equipment when the ship is rocking.
[0013] 3. During the process of deploying the instruments and equipment into the sea, the instruments and equipment are separated from the deployment box in the sea. At the same time, when the instruments and equipment working in the sea are retrieved onto the ship, the instruments and equipment are also fixed in the deployment box in the sea. Therefore, the instruments and equipment only need to sink into the sea more easily than the deployment box to avoid collisions between the instruments and equipment and the deployment box caused by the waves, thereby further avoiding damage to the instruments and equipment.
[0014] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.
[0015] In some implementations, the slide is fixed with a zipper, the outer end of which is connected to one side of the drop box so that when the drop box slides out of the opening of the vessel and falls into the sea, the zipper hooks one side of the drop box onto the opening, while the other side of the drop box tilts and submerges into the sea.
[0016] Based on the above technical solution, the following beneficial effects are further achieved:
[0017] 1. When the sea drop box enters the sea, it can prevent the vibration caused by the collision between the sea drop box and the outer wall of the ship from damaging the instruments and equipment;
[0018] 2. When the drop box is tilted and submerged into the sea on the other side, the stress load on the winch and the rope can be reduced, thereby improving the safety and stability of the ship's operation.
[0019] Since the drop box is not fixedly connected to the ship, and the ship and the drop box will sway with the waves when the ship is at sea;
[0020] Therefore, in some embodiments, a support pivot is provided on the side of the sea-drop box connected to the zipper, and support plates are provided on both sides of the opening, so that when the zipper hangs one side of the sea-drop box at the opening, the support plates limit the support pivot, and the support pivot rotates at the angle between the support plates.
[0021] Based on the above technical solution, the sea-drop box can be pulled down outwards from the ship by its own weight. At this time, the support plate limits the support shaft, thereby preventing the sea-drop box from leaving the slide. At the same time, since the support shaft rotates at the angle between the support plate and the support shaft, it avoids the sea-drop box from rubbing back and forth with the outlet and causing damage.
[0022] In some embodiments, the slide is connected to a swingable gantry frame by bearings on both sides, and the top beam of the gantry frame is provided with a support chain that is fixedly connected to the other side of the launch box.
[0023] Based on the above technical solution, when the other side of the drop box is tilted and submerged into the sea, it can provide auxiliary support for the drop box, thereby further reducing the stress load on the winch and the rope, and thus improving the safety and stability of the ship operation.
[0024] In some implementations, a power module for controlling the swaying of the gantry is installed next to it;
[0025] Based on the above technical solution, when the drop box tilts and submerges into the sea on the other side, the gantry is swayed by the power module to adjust the tilt angle of the gantry, thereby adjusting the tilt angle of the drop box when it submerges into the sea to meet the operational requirements of the instruments and equipment.
[0026] In some implementations, the ship is equipped with a gyroscope to monitor the ship's rolling state when it tilts and submerges into the sea on the other side of the drop box. The power module adjusts the tilt angle of the gantry according to the ship's rolling state so that the drop box can counteract the ship's rolling.
[0027] Based on the above technical solution, when the other side of the launch box is tilted and submerged into the sea, the launch box can maintain a constant angle with the ship, so that instruments and equipment can be stably detached from the launch box or fixed inside the launch box.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided with reference to the accompanying drawings. Example 1
[0035] like Figures 1 to 3 As shown in the figure, this specific embodiment provides an instrument and equipment deployment and retrieval device for use at the stern of a ship, which includes a slide 1 and a drop box 3.
[0036] The slide 1 extends to the stern of the vessel 6. A winch 2 is installed at one end of the slide 1, and the winch 2 winds up a rope 21. The other end of the slide 1 is an opening 61 leading to the outside of the vessel 6. The slide 1 is inclined downward with the opening 61 as the lowest point.
[0037] The sea-launching box 3 has an open structure and is equipped with detachable instruments and equipment. These instruments and equipment are used for launching the equipment into the sea. The outer end of the pull rope 21 is fixedly connected to the sea-launching box 3. Shock absorbers are installed on the components connecting the sea-launching box 3 and the instruments and equipment.
[0038] The following is a description of the operation of the instrument and equipment take-up and take-down device in this embodiment.
[0039] When it is necessary to deploy the instruments and equipment into the sea at depth 5, winch 2 releases the pull rope 21 to a specific length, allowing the launch box 3 to slide into the stern of the vessel 6 via the slipway 1 and then slide out of the vessel 6 through the opening 61 into the sea at depth 5. At this time, the launch box 3 submerges completely into the sea at depth 5, causing it to take on water, and the instruments and equipment are also located in the sea at depth 5. Subsequently, the launch box 3 takes on water in the sea at depth 5, and the instruments and equipment are also located in the sea at depth 5. At this time, the instruments and equipment can operate in the sea with or without being detached from the launch box 3. If the instruments and equipment are detached from the launch box 3, winch 2 retracts the pull rope 21 to pull the launch box 3 back from the sea at depth 5 onto the vessel 6.
[0040] After the instruments and equipment are detached from the drop box 3, and while retrieving the instruments and equipment operating at nautical mile 5 onto the vessel 6, the winch 2 releases the pull rope 21 to a specific length, allowing the drop box 3 to slide into the stern of the vessel 6 via the slide 1 and exit the vessel 6 through the opening 61, falling into the sea at nautical mile 5. At this point, the drop box 3 submerges completely to nautical mile 5, allowing water to enter. Subsequently, the instruments and equipment are secured within the drop box 3 at nautical mile 5. Then, the winch 2 retracts the pull rope 21 to pull the drop box 3 back from nautical mile 5 onto the vessel 6, thereby retrieving the instruments and equipment from the sea onto the vessel 6. Example 2
[0041] like Figures 1 to 3 As shown in the figure, this specific embodiment provides an instrument and equipment launching and recovering device for use at the stern of a ship, including a slide 1, a launch box 3, and a gantry 4.
[0042] Slipway 1 extends to the stern of vessel 6. A winch 2 is installed at one end of slipway 1, and the winch 2 winds up a pull rope 21. The other end of slipway 1 is an opening 61 leading to the outside of vessel 6. Slipway 1 is inclined downward with opening 61 as its lowest point, and support plates 62 are installed on both sides of opening 61. Zippers 11 are fixed on both sides of slipway 1.
[0043] The sea-launching box 3 has an open structure. The outer end of the pull rope 21 is fixedly connected to the rear outer side of the sea-launching box 3, and the outer end of the zipper 11 is also fixedly connected to the rear outer side of the sea-launching box 3. A support pivot 31 is provided on the side of the sea-launching box 3 connected to the zipper 11. A detachable instrument is fixedly installed on the sea-launching box 3. The instrument is used for deployment into the sea at a depth of 5. The density of the instrument is greater than that of the sea-launching box 3 to facilitate its sinking into the sea at a depth of 5. Shock absorbers are provided on the components connecting the sea-launching box 3 and the instrument.
[0044] The gantry 4 is connected to the slide rail 1 by bearings on both sides. The top beam of the gantry 4 is equipped with a support chain 41 fixedly connected to the upper outer front side of the launch box 3. A power module 42 is installed beside the gantry 4. The power module 42 can be a hydraulic cylinder, a pneumatic cylinder, or a reel capable of pulling and releasing ropes to drive the gantry 4 to swing. The vessel 6 is equipped with a gyroscope that works in conjunction with the power module 42.
[0045] The following is a description of the operation of the instrument and equipment take-up and take-down device described in this embodiment.
[0046] When the instruments and equipment need to be deployed into the sea (5), the winch 2 releases the pull rope 21 to a specific length, allowing the launch box 3 to slide into the stern of the vessel 6 via the slide 1. At this time, the zipper 11 attaches the launch box 3 to the opening 61 on one side, while the other side of the launch box 3 tilts and submerges into the sea (5). The support plate 62 limits the support shaft 31, which rotates at the angle between the support plate 62 and the support shaft 31. The gantry 4 is also pulled towards the stern of the vessel 6 by the launch box 3 and tilts accordingly. Simultaneously, the gyroscope monitors the swaying state of the vessel 6, and the power module 42 adjusts the tilt angle of the gantry 4 based on the swaying state of the vessel 6, so that the launch box 3 counteracts the swaying of the vessel 6, thus maintaining a constant angular relationship between the launch box 3 and the vessel 6, and providing support for the launch box 3. Subsequently, the launch box 3 takes on water in the sea (5), and the instruments and equipment are also located in the sea (5). At this time, the instruments and equipment can operate in the sea, either detached from or not detached from the launch box 3. If the equipment is detached from the drop box 3, the winch 2 retracts the pull rope 21, and at the same time, the power module 42 drives the gantry 4 to swing towards the bow of the ship 6 to pull the drop box 3 from the sea 5 back onto the ship 6.
[0047] After the instruments and equipment are detached from the launch box 3, and during the retrieval of the instruments and equipment operating at sea level 5 onto the vessel 6, the winch 2 releases the pull rope 21 to a specific length, allowing the launch box 3 to slide into the stern of the vessel 6 via the slide 1. At this time, the zipper 11 attaches the launch box 3 to the opening 61 on one side, while the other side of the launch box 3 tilts and submerges into the sea level 5. The support plate 62 limits the support shaft 31, which rotates at the angle between the support plate 62 and the support shaft 31. The gantry 4 is also pulled towards the stern of the vessel 6 by the launch box 3 and tilts accordingly. Simultaneously, the gyroscope monitors the swaying state of the vessel 6, and the power module 42 adjusts the tilt angle of the gantry 4 according to the swaying state of the vessel 6, so that the launch box 3 counteracts the swaying of the vessel 6, thereby maintaining a constant angular relationship between the launch box 3 and the vessel 6, and providing support for the launch box 3. Subsequently, the instruments and equipment can be fixed inside the launch box 3 at sea level 5. Subsequently, winch 2 retracts the pull rope 21, and at the same time, power module 42 drives gantry 4 to swing towards the bow of ship 6 to pull the drop box 3 from the sea 5 back onto ship 6, thereby recovering the instruments and equipment from the sea onto ship 6.
