Description

Technical Field

[0001] This utility model relates to the field of CTD seawater sampling equipment deployment and recovery, and in particular to a protective device for CTD seawater sampling equipment deployment and recovery. Background Technology

[0002] The CTD (Conductivity, Temperature, and Depth) seawater sampling device is a tool used in marine research. It is specifically designed to measure seawater temperature, salinity, and depth, collecting data in real time through sensors and transmitting it back to researchers. This data helps scientists understand the physical and chemical properties of seawater, ocean currents, and other complex phenomena.

[0003] Existing CTD seawater sampling equipment is lifted upwards by steel cables when retrieved from the ocean. However, factors such as ocean currents, wind, and waves can impact the equipment, causing it to shake significantly during retrieval. This can lead to collisions between the equipment and the ship, resulting in equipment damage or loss of control, and affecting the accuracy of subsequent data. Utility Model Content

[0004] The main purpose of this utility model is to provide a deployment and recovery protection device for CTD seawater sampling equipment, which can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A deployment and recovery protection device for a CTD seawater sampling equipment includes a sampling component, a connecting plate on the sampling component, a plurality of connecting columns fixedly connected to one side of the connecting plate, the plurality of connecting columns being evenly spaced in an array, a fixing ring fixedly connected to one end of each connecting column, and a connecting groove formed between the connecting column and the fixing ring; a fixing plate is disposed directly above the fixing ring, two sets of connecting hooks are disposed on one side of the fixing plate, the two sets of connecting hooks being symmetrically distributed about the central axis of the fixing plate, one end of each connecting hook extending into the connecting groove, and one side of each connecting hook fitting against one side of the fixing ring; a moving component is disposed on the fixing plate for driving the connecting hooks to move, and a lifting component is disposed on the fixing plate.

[0007] As a further embodiment of this utility model, the movable component includes two sets of movable slots formed on the fixed plate. The two sets of movable slots are symmetrically distributed about the central axis of the fixed plate. A movable plate is slidably disposed in the movable slot, and one end of the movable plate is fixedly connected to one end of the connecting hook.

[0008] As a further embodiment of this utility model, the moving component also includes two sets of cylinders disposed on the fixed plate. The two sets of cylinders are symmetrically distributed about the central axis of the fixed plate, and one end of each cylinder is fixedly connected to one side of the moving plate.

[0009] As a further embodiment of this utility model, a sliding rod is fixedly connected inside the movable groove, and the sliding rod passes through the movable plate.

[0010] As a further embodiment of this utility model, the lifting member includes a first connecting ring fixedly connected to one side of the connecting plate, and a first steel rope connected to the first connecting ring.

[0011] As a further embodiment of this utility model, the lifting member also includes a plurality of second connecting rings disposed on one side of the fixed plate, and a second steel rope is fixedly connected to the second connecting rings.

[0012] As a further embodiment of this utility model, the fixed plate is provided with a movable groove, the movable groove is adapted to the first steel rope, and a buffer pad is fixedly connected to the outer surface of the sampling component.

[0013] The beneficial effects of this utility model are as follows:

[0014] After the sample is lifted to the water surface by the lifting mechanism, the fixing plate is placed above the fixing ring. The moving component then moves the connecting hook into the connecting groove, where it engages with the fixing ring. The lifting mechanism then lifts the fixing ring, which, in conjunction with the connecting column and connecting plate, raises the sample upwards. Multiple support points working with the lifting mechanism prevent the equipment from being subjected to tension in only one direction, ensuring even distribution of external water pressure. This effectively reduces changes in water flow direction and avoids swaying caused by instability. This addresses the potential impact of ocean currents, wind, and waves on the equipment, significantly reducing equipment swaying during recovery and greatly minimizing the chance of damage or loss of control. This increases the equipment's protection and prevents interference with the accuracy of subsequent data. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, a deployment and recovery protection device for a CTD seawater sampling equipment includes a sampling component 1, a connecting plate 2 on the sampling component 1, a plurality of connecting columns 3 fixedly connected to one side of the connecting plate 2, the plurality of connecting columns 3 being evenly spaced in an array, a fixing ring 4 fixedly connected to one end of the connecting column 3, and a connecting groove 15 being formed between the connecting column 3 and the fixing ring 4; a fixing plate 5 is provided directly above the fixing ring 4, and two sets of connecting hooks 6 are provided on one side of the fixing plate 5, the two sets of connecting hooks 6 being symmetrically distributed about the central axis of the fixing plate 5.

[0023] In this embodiment, one end of the connecting hook 6 extends into the connecting groove 15, and one side of the connecting hook 6 is attached to one side of the fixing ring 4; a moving component is provided on the fixing plate 5, which is used to drive the connecting hook 6 to move, and a lifting component is provided on the fixing plate 5.

[0024] To enhance protection during sample recovery, the sample 1 is first lifted to the water surface by a lifting component. Then, the fixing plate 5 is placed above the fixing ring 4. A moving component moves the connecting hook 6 into the connecting groove 15, where it engages with the fixing ring 4. The lifting component then lifts the fixing ring 4, which, in conjunction with the connecting column 3 and connecting plate 2, raises the sample 1 upwards. Multiple support points working with the lifting component prevent the equipment from being subjected to tension in only one direction, ensuring even distribution of external water pressure. This effectively reduces changes in water flow direction and avoids swaying caused by instability. This addresses the potential impact of ocean currents, wind, and waves on the equipment, significantly reducing equipment swaying during recovery and minimizing the risk of damage or loss of control. This increases equipment protection and prevents interference with the accuracy of subsequent data.

[0025] Meanwhile, the lifting component also includes several second connecting rings 13 set on one side of the fixed plate 5. A second steel rope 14 is fixedly connected to the second connecting ring 13. By using multiple sets of second connecting rings 13 in conjunction with the second steel rope 14, multiple tension points are increased, so that the force is evenly distributed. Therefore, the shaking or swaying of the equipment under the action of water flow will be restricted.

[0026] In this embodiment, the moving component includes two sets of moving slots 7 formed on the fixed plate 5. The two sets of moving slots 7 are symmetrically distributed about the central axis of the fixed plate 5. A moving plate 8 is slidably disposed in the moving slot 7. One end of the moving plate 8 is fixedly connected to one end of the connecting hook 6. The moving component also includes two sets of cylinders 10 disposed on the fixed plate 5. The two sets of cylinders 10 are symmetrically distributed about the central axis of the fixed plate 5. One end of the cylinder 10 is fixedly connected to one side of the moving plate 8.

[0027] The cylinder 10 drives the moving plate 8 to slide inside the moving groove 7. The moving plate 8 drives the connecting hook 6 to move into the connecting groove 15, which facilitates the adjustment of the position of the connecting hook 6, increases the convenience of using the equipment, and makes it easier for the staff to operate the equipment.

[0028] The sliding groove 7 is fixedly connected to a sliding rod 9, which passes through the sliding plate 8. When the sliding plate 8 moves, the sliding rod 9 restricts the position of the sliding plate 8 and increases the support of the connecting hook 6, thereby increasing the stability of the equipment during use.

[0029] In this embodiment, the lifting component includes a first connecting ring 11 disposed on one side of the connecting plate 2, and a first steel rope 12 is connected to the first connecting ring 11.

[0030] The first connecting ring 11, in conjunction with the first steel rope 12, facilitates the lifting of the sample 1 from the seawater.

[0031] In this embodiment, the fixed plate 5 is provided with a movable groove 17, which is adapted to the first steel rope 12, and the outer surface of the sampling component 1 is fixedly connected with a buffer pad 16.

[0032] The movable slot 17 allows the fixing plate 5 to be placed above the fixing ring 4, while the buffer pad 16 reduces the impact force when the sample 1 comes into contact with the hull, further protecting the sample 1.

[0033] It should be noted that this utility model is a deployment and recovery protection device for CTD seawater sampling equipment. In use, the first connecting ring 11 in the lifting component, in conjunction with the first steel rope 12, firstly lifts the sampling component 1 to the water surface. Then, the fixing plate 5 is placed above the fixing ring 4. The cylinder 10 drives the moving plate 8 to slide inside the moving groove 7. The moving plate 8 moves the connecting hook 6, causing it to move into the connecting groove 15 and engage with the fixing ring 4. Then, the first connecting ring 11, the first steel rope 12, and multiple sets of second connecting rings 13 in conjunction with second steel ropes 14 lift the fixing ring 4. The fixing ring 4, in conjunction with the connecting column 3 and the connecting plate 2, lifts the sampling component 1 upwards. Through multiple support points and the lifting component, the equipment is not subjected to tension in only one direction, but rather the external water flow pressure is evenly distributed. This effectively reduces changes in the direction of the water flow and avoids swaying caused by instability.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
