Description

Technical Field

[0001] The invention relates to the technical field of underwater surveying and mapping stabilization, in particular to a stabilization device for underwater surveying and mapping instruments. Background Art

[0002] Underwater surveying instruments usually include ultrasonic transducers and depth sounders. These devices measure depth by emitting sound waves and calculating the time difference between the sound waves and the reflected waves. Through continuous measurement, underwater topographic maps or cross-sectional maps can be drawn. The working principle of underwater surveying instruments mainly relies on the reflection phenomenon of ultrasonic waves between media. At present, single-beam echo sounders are widely used. They only emit one beam of sound waves each time and record one water depth data point. Through continuous measurement, underwater topography is drawn in a point-to-point manner, which plays a vital role in many fields such as marine scientific research, navigation, and seabed resource exploration.

[0003] The existing stabilizing devices for underwater surveying and mapping instruments have the following deficiencies in use: first, when installing the surveying and mapping instrument, the underwater surveying and mapping instrument is usually carried to the hull, placed in a preset installation groove, and then secured with bolts or a snap-fit ​​structure to maintain stability. The form is single. Although this operation can prevent the surveying and mapping instrument from shaking in the hull installation groove, the vibration of the hull will cause errors in the reception and transmission of sound waves by the acoustic wave surveying and mapping equipment, affecting its performance and accuracy, and will also affect the propagation characteristics of the sound waves, including the propagation speed, direction and intensity, which may cause distortion of the signal received by the acoustic wave equipment and affect its detection and positioning accuracy.

[0034] In view of the above technical solution, the positioning and stabilizing seat 3 is installed in the small carrier boat 1, the opening and closing plate 10 of the stabilizing placement chamber 9 is opened, and the stabilizing box 27 is placed in the rear clamping block 45 to contact with the L-shaped clamping head 46 and enter the through opening. After the surveying and mapping operation begins, the small carrier boat 1 moves, and the water flow pushes the guide blade 7 to move, so that the fan-shaped sealer 31 is driven to slide in the water base 24. When the guide blade 7 moves, the traction long rod 6 is pushed backward to move, and the limit gasket 30 is driven to move in the opening during the movement, and then the bridging strip 13 is driven to rotate in the positioning rotating frame 18, and the linkage rod 16 is further pulled to move downward, and then the pressure plate 29 is driven downward, so that after the linkage pressure frame 15 is driven to move, the sliding sleeve 14 is driven to slide on the surface of the positioning column 12, and the telescopic clamping rod 32 is synchronously lowered under the drive of the linkage pressure frame 15.

[0036] According to the above technical solution, the mounting bracket 22 is driven to move by the telescopic card rod 32.

[0039] The embodiment of the present invention further provides a stabilizing device for an underwater surveying and mapping instrument, and the specific working principle includes the following steps:

[0040] By installing the positioning stabilizing seat 3 in the small carrier boat 1, opening the opening and closing plate 10 of the stabilizing chamber 9, placing the stabilizing box 27 in the rear clamping block 45 to contact the L-shaped clamping head 46 and enter the through opening, the small carrier boat 1 moves after the surveying and mapping operation begins, and the water flow pushes the guide blade 7 to move, so that the fan-shaped sealer 31 slides in the water base 24, and the guide blade 7 moves to push the traction rod 6 backward to move, and the limit gasket 30 moves in the opening during the movement, thereby driving the bridge strip 13 on the positioning rotating frame 18 rotates, further pulling the linkage rod 16 to move downward and drive the pressing plate 29 to move downward, so that after driving the linkage pressing frame 15 to move, the sliding sleeve 14 is driven to slide on the surface of the positioning column 12, and the telescopic card rod 32 is synchronously lowered under the drive of the linkage pressing frame 15. During the descent, the telescopic card rod 32 drives the mounting bracket 22 to move, and the mounting bracket 22 drives the limit roller 23 to roll downward in the guide groove 47 after the movement. At this time, the telescopic card rod 32 will slide in the linkage pressing frame 15, so that the mounting bracket 22 moves the limit spring 28. The telescopic card rod 32 can drive the sealing plate 26 to move in the restriction port 25 when it moves, so that the L-shaped card head 46 is tightly against the card block 45, and the switch of the data electronic controller 11 is triggered after passing through the through port. When the surveying and mapping hull moves, the balance hanger 34 will move in the direction of rotation, thereby driving the driven bridge piece 37 to move in the elastic limit head 38, and the elastic limit head 38 on the other side rotates on the inner wall of the stability box 27, so that the limit ball 41 is in the limit half set 3 after the short rod 35 moves. 6 swings inside, and the balance hanger 34 always remains in a vertical state, thereby keeping the mounting rod vertical. Water flows in from the water inlet 42, and the surveying and mapping probe 33 starts to emit sound waves for underwater surveying and mapping operations. The frequency range of the sound waves is relatively wide and can be adjusted as needed. In underwater surveying and mapping, we can choose the appropriate sound wave frequency according to demand to obtain better detection effect. In order to prevent water from filling the interior of the positioning and stabilizing seat 3, the micro water pump 19 can be started to suck water from the water inlet pipe 21 and then discharge it through the water outlet pipe 20.
