Description

Technical Field

[0001] This invention relates to the field of marine measurement technology, and more specifically, to a pressure-triggered waterproof GPS positioning device for marine measurement. Background Technology

[0002] Marine surveying refers to the measurement and charting work carried out on ocean waters and seabed. As the foundation of all economic activities at sea, marine surveying requires the use of various surveying equipment to obtain data such as location, water depth, seabed sediment, gravity, magnetism, hydrology, and meteorology. During the use of surveying equipment, positioning devices are usually required for the positioning, installation, and adjustment of the surveying equipment. However, when conducting marine surveying in coastal areas and island areas, due to the windy marine climate, surveyors need to ensure that the positioning devices have sufficient stability to prevent them from being blown by the sea wind, which would cause the surveying equipment to shake and affect the surveying accuracy. Furthermore, since the work is carried out at sea, the waterproofing of GPS positioning devices is necessary.

A sliding groove 52 is formed on the inner bottom wall of the support platform 25. Slider 53s are symmetrically connected inside the sliding groove 52. The slider 53s are connected to the screw... Connecting blocks 54 are fixedly connected to each of the sliders 28. The control mechanism includes a controller 55, which is mounted on one side of the GPS body 31. The first forward / reverse motor 17, the second forward / reverse motor 22, the third forward / reverse motor 26, the hydraulic telescopic rod 4, and the electric telescopic rod 15 are all electrically connected to the controller 55. The controller 55 is also electrically connected to the pressure sensor 6 and the seawater collector 5. By setting up the control mechanism, the control switches for the first forward / reverse motor 17, the second forward / reverse motor 22, the third forward / reverse motor 26, the hydraulic telescopic rod 4, and the electric telescopic rod 15 can be centralized in one place, thus facilitating control by the controller 55.

[0038] In practical applications, the hydraulic telescopic rod 4 is activated, which moves the seawater collector 5 and pressure sensor 6 towards the seabed. This allows for the collection of seawater at different depths based on the values ​​transmitted by the pressure sensor 6. The seawater collector 5 transports seawater to the collection tank 1 through the delivery pipe 7 until the seawater reaches the position of the water level detector 8. At this point, the controller 55 stops the seawater collector 5. Then, the electric telescopic rod 15 is activated, which moves the connecting plate 14 and piston rod 13 back and forth, causing the piston 12 to move back and forth inside the piston cylinder 11. When the piston 12 pushes inward, check valve 1 39 is open and check valve 2 41 is closed, allowing the piston 12 to expel gas from the piston cylinder 11 through the exhaust pipe 38. When the piston 12 extends outward, check valve 1 39 is closed and check valve 2 41 is open, allowing the suction pipe 40 to draw gas from the detection chamber 10 into the piston cylinder 11. This process repeats, allowing the detection... The air pressure inside chamber 10 decreases, and control valve 21 is opened. Under pressure, seawater from collection box 1 enters detection chamber 10 through pumping pipe 20. Control valve 21 is closed, and forward / reverse motor 17 is started. Forward / reverse motor 17 drives threaded rod 18 to rotate, which causes threaded sleeve 19 to move detection head 56 downward, enabling seawater detection and facilitating marine surveying. When it is necessary to remove GPS body 31, top cover 45 is opened, and forward / reverse motor 22 is started. Forward / reverse motor 22 drives threaded rod 23 to rotate, which causes threaded sleeve 24 to move support platform 25 and GPS body 31 upward, allowing GPS body 31 to extend out of waterproof box 3. Then, forward / reverse motor 326 is started, which drives threaded rod 27 to rotate. Since the threads at both ends of threaded rod 27 are opposite, threaded rod 27 drives the threaded sliders 28 at both ends to move in opposite directions, causing clamp 30 to leave GPS body 31, allowing GPS body 31 to be removed.
