Description

Technical Field

[0001] This invention relates to the field of buoy recovery technology, and in particular to a buoy recovery device for marine observation. Background Technology

[0002] Marine pollution generally refers to human activities that alter the original state of the ocean, causing damage to the marine ecosystem. Pollution caused by harmful substances entering the marine environment can damage biological resources, endanger human health, hinder fishing and other human activities at sea, and damage seawater and environmental quality. Therefore, it is necessary to deploy buoys in the ocean to monitor ocean dynamics in a timely manner through data collection.

[0003] After completing their oceanographic observation tasks, buoys need to be collected and retrieved in a unified manner. This is to prevent pollution of the ocean by abandoned buoys and to allow for reuse, reducing production costs. Currently, buoy retrieval is usually done manually, which is time-consuming, labor-intensive, and inefficient. This is especially true when dealing with larger buoys, making successful retrieval even more difficult. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a buoy recovery device for marine observation. It features a reasonable structural design, convenient operation, and uses mechanical methods to replace manual retrieval, effectively reducing the labor intensity of workers. While improving work efficiency, it can also be adjusted according to the size of the buoy to meet the needs of retrieving buoys of different sizes and volumes.

[0029] Optionally, the robotic arm mechanism includes a boom 22, the lower end of which is movably hinged to a lower hinge seat 19, and the upper end of which is movably hinged to a hydraulic cylinder 20.

[0030] Optionally, the clamping block 27 has an arc-shaped cross-section.

[0031] Optionally, the storage mechanism includes a storage compartment 29 that is horizontally connected to the front / rear sidewall of the floating platform 1.

[0032] Optionally, a number of drainage holes 32 are provided horizontally along the edge of the lower part of the storage chamber 29. Seawater enters and exits through the drainage holes 32, which can reduce the resistance caused by the storage chamber 29.

[0033] Optionally, the floating support 3 includes two clamping plates 301 arranged parallel to each other on the front / rear sidewalls of the floating platform 1, an airbag fixing seat 302 is provided between the two clamping plates 301, the outer end of the airbag fixing seat 302 is connected to the floating airbag 303, the inflation nozzle 304 of the floating airbag 303 is provided on the airbag fixing seat 302, and a number of reinforcing rods 305 connected to the floating platform 1 are provided on the upper clamping plate 301.

[0035] Before use, this device needs to be connected to the drive unit, which provides the power source. The device floats on the sea surface along with the drive unit. The adjusting nut 7 drives the adjusting screw 6 to rotate. As the adjusting screw 6 rotates, it moves the two guide arms 8 in the same / opposite directions, thus adjusting the guiding distance between the two guide arms 8 to suit buoys of different sizes. In use, the drive unit propels the device forward on the sea surface. When a buoy is detected, it slowly approaches it, guiding the buoy into the arm 22 using the two guide arms 8. At this time, the servo motor 25 starts, driving the drive screw 26 to rotate, causing the moving slider 24 to move back and forth along the arm 22 until it reaches the buoy. Then, the clamping cylinder 28 is activated, causing the clamping blocks 27 to extend outwards, clamping the bottom of the buoy and securing it securely. Restart the hydraulic cylinders 20, causing them to pull the two booms 22 upwards along the lower hinge seat 19. Then, start the drive motor 15. The output shaft of the drive motor 15 drives the circular base plate 11 to rotate via the drive gear 16. The circular base plate 11 rotates horizontally along the direction of the positioning post 12, thereby causing the two booms 22 holding the buoy to rotate out of the opening 31 of the storage compartment 29. Note that at this time, the sliding blocks 24 on the two booms 22 move inwards, causing the buoy to move inwards as well, aligning with the opening 31 of the storage compartment 29. Then, lower the two booms 22, releasing the two clamping blocks 27, and the buoy falls into the storage compartment 29. With the impact of the seawater, it moves towards the outer end of the storage compartment 29. The floating support seats 3 on both sides mainly serve as stabilizing devices, reducing the impact of waves on the clamped buoy. Its structure is reasonable and easy to operate. It adopts mechanical means to replace manual salvage, which effectively reduces the labor intensity of workers. While improving work efficiency, it can also be adjusted according to the size of the buoy to meet the needs of salvaging buoys of different sizes and volumes. It has strong versatility and can quickly and continuously complete the buoy recovery work. Moreover, the salvaged buoys do not occupy additional cabin space, which effectively improves the space utilization of this device and solves the problems existing in the prior art.
