Problems solved by technology

On the one hand, its tilting back and forth and swaying left and right caused the precision scientific detection instruments installed at the bottom of the fins to fail to work normally when the elevating fins were in the cruising state; on the other hand,
The shaking of the lift fin will cause it to hit the hull, and the lift fin and the hull will be damaged. Therefore, the lift fin needs to be locked by a locking device in the maintenance state and cruise state to solve the above problems

Embodiment 1

[0026] like Figure 1-3 , a locking device based on lifting fins under maintenance state and cruising state, which includes hydraulic locking mechanisms symmetrically arranged on both sides of the two wide arc-shaped walls of the lifting fin 11; the two lifting fins 11 A mechanical locking mechanism for locking the lifting fin 11 is arranged symmetrically on both sides of the narrow arc-shaped wall; a hook auxiliary locking mechanism is provided between the lifting fin 11 and the lifting fin connection 12 . The locking device with the above-mentioned structure can be used for locking the lifting fin 11 , and the locking reliability can be ensured by the hydraulic locking mechanism, the mechanical locking mechanism and the hook auxiliary locking mechanism.

[0027] Further, the hydraulic locking mechanism includes a symmetrically arranged hydraulic cylinder 1, and the end of the piston rod of the hydraulic cylinder 1 is equipped with an arc-shaped wedge plate 2 for matching wit...

Embodiment 2

[0033] The method for using any one of the liftable fin hydraulic lifting devices includes the following steps:

[0034] Step1: When the lifting fin 11 is in the cruising state, the piston rods of the two hydraulic cylinders 1 symmetrically distributed on the left and right sides of the lifting fin extend out at the same speed, and the arc-shaped wedge plate 2 at the end of the piston rod acts on the lifting The force of the left and right curved surfaces of the fins is equal to ensure that the lifting fins are placed vertically, thus completing the locking action of the lifting fins in the maintenance state;

[0035] Step2: When the lifting fin is in the maintenance state, the stepper motor 3 drives the screw 4 to rotate, and the slidable push block 5 set on the screw 4 will lock the wedge plate 6 to the front end of the lifting fin Lock with the rear end;

[0036]Step3: During the sailing process of the ship, in order to prevent the lifting fins in the maintenance state fro...

Abstract

The invention discloses a locking device based on a lifting fin in a maintenance state and a cruising state and a use method. The locking device based on the lifting fin in the maintenance state and the cruising state comprises hydraulic locking mechanisms which are symmetrically arranged on the two sides of two wide arc walls of the lifting fin; mechanical locking mechanisms used for locking thelifting fin are symmetrically placed and mounted on the two sides of two narrow side arc walls of the lifting fin; and a hook auxiliary locking mechanism is arranged between the lifting fin and a lifting fin connector. The locking device based on the lifting fin in the maintenance state and the cruising state has the characteristics that the lifting fin in the maintenance state is locked by usingsymmetrically distributed hydraulic cylinder locking mechanisms; and meanwhile, by using a stepping electric motor mechanical locking mechanism based on pressure detection, a stepping electric motor driving mechanical device is controlled to lock the lifting fin plate in the maintenance state by using a pressure automatic detecting mode.

Description

technical field [0001] The invention relates to a locking device and a using method of a lifting fin based on a maintenance state and a cruising state, and belongs to the field of ship devices. Background technique [0002] Marine resources have gradually become the focus of attention of coastal countries. The first thing to be solved in the development of marine science and technology is to conduct scientific investigation and research on marine resources. As a mobile laboratory, scientific research ships have become the first choice for marine on-site research, and can be equipped with advanced research equipment in land laboratories. Compared with land laboratories, the working environment of scientific research ships is harsh. In order to install and use precision instruments in this environment, the lifting fin system came into being. Lifting fins are mainly used to install scientific experimental instruments at the bottom of the fins that can be used for seabed detect...
