Boat sonar retracting and releasing mechanism

Abstract

The invention relates to a boat sonar retracting and releasing mechanism. The retracting and releasing mechanism comprises a turning plate set, a lead screw nut set, a chain transmission set, a motor and a fast-assembly base. The turning plate set comprises a sonar mounting seat and a telescopic mechanism; a sonar main body is mounted on the sonar mounting seat, and the sonar mounting seat is connected with the telescopic mechanism; the two sides of the bottom of the turning plate set are symmetrically hinged to the two lead screw nut sets; the lead screw nut sets and the motor are installed on the fast-assembly base, and the two lead screw nut sets are connected with the motor through the chain transmission set; the fast-assembly base is mounted on a ship bow; the motor and the telescopic mechanism are automatically controlled through a PLC, and the motor drives the two lead screw nut sets through the chain transmission set to synchronously drive the turning plate set to turn over; and the telescopic mechanism drives the sonar mounting seat to automatically stretch out and draw back. The ship bow does not need to be independently designed, rapid disassembly and assembly are achieved, overturning, water entering and water exiting of the sonar can be rapidly completed according to requirements, and the overturning angle and the water entering depth can be freely adjusted within the preset range.

Description

technical field [0001] The invention relates to a sonar retractable mechanism, in particular to a sonar retractable mechanism for a boat. Background technique [0002] Currently in the period of rapid development of marine science and technology and marine economy, according to the needs of marine resource development, underwater detection equipment has become an indispensable tool, among which underwater sonar detection equipment is the most widely used. Underwater sonar detection equipment uses the reflected echoes of sound waves in water to detect and image targets or the bottom of the water. The quality of underwater sonar detection and imaging depends on the technical level of the equipment itself. It greatly affects the detection imaging effect. [0003] In recent years, small and medium-sized surface ships that are manually or automatically driven have become the main tools for ocean exploration, especially self-driving unmanned ships have become a hot spot, so how t...

Problems solved by technology

In addition, in addition to the towed sonar system that can be installed at the stern, the fixed underwater sonar is not ideal for detection and imaging due to the disturbance of the hull itself and the turbulence at the stern, so most of them are not installed at the stern

[0005] The utility model patent CN211869606U discloses a sonar lifting device installed in the storage cabin. By adopting the structural form of the main rod stretching and the auxiliary rod folding, the rapid retraction operation of the sonar head in a limited space is realized. Since it is arranged in the bottom storage cabin Among them, it can effectively reduce the overall center of gravity and improve stability. Although it effectively increases the operating depth and improves the efficiency of submarine exploration operations, it does not occupy deck space and does not affect the installation of other detection equipment, but the sonar storage cabin requires a large space and the space utilization rate Not high, inconvenient for maintenance and replacement, in addition, there are high requirements for the sealing of the storage cabin

The opening of the bilge cover will also cause disturbances in the operation of the hull, affecting its high-speed operation

[0006] The utility model patent CN209417293U discloses a high-stability underwater detection sonar, which can realize the appropriate adjustment of the horizontal, vertical and depth attitude of the sonar mounting seat, and avoid the influence of the hull disturbance on the imaging effect. Although it has a high degree of attitude stability, However, this solution can only be fixedly installed on the side or bottom of the ship, and cannot realize automatic retraction into and out of the water

[0007] Invention patent CN101811562A discloses an underwater side-scan sonar retractable device installed under the bow deck, which drives the retractable rod to rotate and send the sonar into the Underwater, although the function of automatic flip and release is realized, since the 90-degree flip is performed from the inside of the bow to the outside, the bow needs to be designed and slotted separately, which takes up extra space

[0008] Invention patent CN110356513B discloses an auxiliary sonar release and recovery mechanism for unmanned boats. The rotary hinge is used to realize the 270-degree flip of the mechanism, and the depth adjustment and release are realized through the electric cylinder assembly. The mechanism is directly arranged at the bow deck, which can completely turn the sonar It is recovered to the deck, which is convenient for maintenance and replacement, and saves storage space. However, the overturning range is large, and it is easy to cause vibration of the hull during the overturning process, which affects the operation. The depth release adjustment structure uses the electric cylinder directly as a supporting structure, and its strength is weak. Long-term impact by water pressure during operation, resulting in damage to the electric cylinder
