Description

Technical Field

[0001] The invention belongs to the technical field of ocean detection equipment, and in particular relates to an anti-collision device for an ocean depth sounder. Background Art

[0002] An ocean depth sounder is an instrument used to measure the depth of water bodies and is widely used in fields such as ocean surveys, channel measurements and marine engineering. It calculates water depth by emitting sound waves and receiving their reflected echoes, usually using sonar technology. Ocean depth sounders are divided into two types: single-beam and multi-beam. Single-beam depth sounders are suitable for depth measurements in smaller areas, while multi-beam depth sounders can simultaneously obtain depth data over a larger range, providing higher measurement accuracy. Modern ocean depth sounders are also equipped with advanced navigation systems and data processing software that can display measurement results in real time and generate detailed seabed topographic maps to help scientists and engineers better understand the marine environment.

[0003] When in use, the ocean depth sounder needs to be placed in water and towed by a ship for detection. Due to the complex terrain in shallow sea areas, the depth sounder is easily hit by reefs underwater and cannot be effectively avoided, which causes damage to the depth sounder and affects the effective use of the depth sounder.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) During operation, the ocean depth sounder anti-collision device is provided with a main rod, an anti-collision plate, a connecting rope, a depth sounder, a towing rope, a front end collision separation chamber, a stabilizing support rod, a folding adjustment member, a water delivery member, an extrusion rod and an active avoidance member, so that the ocean depth sounder anti-collision device has an impact buffer structure and an active impact avoidance structure. The impact buffer structure can reduce the impact on the depth sounder during a collision. At the same time, the active impact avoidance function is activated through the linkage adjustment of the impact buffer structure, so that the active impact avoidance can squeeze and deliver pressurized water during a collision to make the depth sounder deviate from the original driving track, thereby effectively avoiding the depth sounder from collision;

[0015] At the same time, the anti-collision device of the ocean depth sounder has a simple structural design, and the protection and anti-collision avoidance adjustment are stable and reliable, and its performance can meet the use requirements of the ocean depth sounder;

[0016] (2) When the towing boat moves the main pole, four anti-collision plates, connecting rope and depth sounding instrument in the water by the towing rope, the first thing to be collided is any collision rod on any collision plate. After the collision, the collision rod will be squeezed into the inside of the sleeve and push the extrusion block and the adjustment rod to move and compress the spring A. The movement of the adjustment rod will drive the ring to move. The movement of the ring will squeeze and pull the cable A. The cable A has a certain length margin to avoid small collisions or movement in the water, which will cause the collision rod to be squeezed and cause the cable A to move. The squeezed and pulled movement of the cable A will pull the two cables B to move through the pulley A. The movement of the two cables B will pull the moving block to move through the pulley B.

[0017] When the moving block moves inside the inner cavity and compresses the spring B and drives the limit stop pin to move, the limit stop pin will be removed from the top of the limit stop block. At this time, the elastic restoring force of the spring C will pull the limit stop block to move to the upper part of the inverted T-shaped inner groove; and the movement of the limit stop block will drive the T-shaped rod to move out of the inverted T-shaped inner groove; and by pressing the T-shaped rod to insert it into the inverted T-shaped inner groove, the movement of the T-shaped rod will push the limit stop block to move and stretch the spring C, and at the same time, the elastic restoring force of the spring B will move the limit stop pin to the top of the limit stop block to limit and block it.

[0018] When the anti-collision plate and the impact rod thereon are impacted, the limit stopper will be removed from between the rod body 1 and the rod body 2 through transmission, and then the anti-collision plate will rotate through the impact. The rotation of the anti-collision plate will cause the rod body 1 and the rod body 2 to rotate and fold through the mounting block, so that the impacted anti-collision plate can be buffered during the rotation to avoid affecting the depth measuring instrument;

[0019] When the anti-collision plate rotates, it will push the adjusting rod A to move. The movement of the adjusting rod A will push the adjusting rod B to be inserted into the interior of the cylinder and push the extrusion piston to move. The movement of the extrusion piston will squeeze and push the water and air into the water hose and transport them to the inside of the ring tube through the action of the one-way valve. Finally, the water and air will be ejected through the one-way water outlet valve. The inference generated by the ejected water and air will cause the depth sounder to deviate from the side of the anti-collision plate that is hit and rotated, thereby keeping the depth sounder away from reefs, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] When the towing boat pulls the main pole 1, four anti-collision plates 2, connecting rope 3 and depth sounder 4 through the towing rope 5 to move in the water, the first to be collided is any collision rod 14 on any collision plate 2. After the collision, the collision rod 14 will be squeezed into the inside of the sleeve 12 and push the squeezing block 13 and the adjusting rod 15 to move and compress the spring A16. The movement of the adjusting rod 15 will drive the ring 17 to move. The movement of the ring 17 will squeeze and pull the cable A18. The cable A18 has a certain length of margin to avoid small collisions or movement in the water, which will cause the collision rod 14 to be squeezed and cause the cable A18 to move. The squeezed and pulled movement of the cable A18 will pull the two cables B27 to move through the pulley A19. The movement of the two cables B27 will pull the moving block 26 to move through the pulley B25.
