The invention relates to the technical field of marine equipment, in particular to a vertical lifting ship floating condition adjusting device and a working method thereof. The servo motor is used for controlling the blades of the interceptor to move up and down, in cooperation with transmission of a slider-crank mechanism and positioning of a gear and a rack, the positions of the blades can be adjusted in a high-precision mode, control over the posture of a ship body under various working conditions is achieved, and meanwhile light weight of the device is fully considered in the material type selection and structure design process; and the influence of the device on the overall structural design of the ship can be effectively reduced. The blade extension amount can be automatically adjusted according to the sailing state and sailing parameters of the ship body, then the resistance in the ship body acceleration process is remarkably reduced, the ship acceleration efficiency is improved, meanwhile, the sailing posture of the ship body can be adjusted, the sailing stability is improved, fuel consumption is reduced, and the application prospect is wide.

The present invention provides a manually operated diaphragm valve that maintains compactness through a simple construction while simultaneously allowing for setting the valve body's opening and closing range. This design is unaffected by individual differences in the valve's internal shape, ensuring sufficient flow rate when fully open, and also allowing for arbitrary adjustment of the fully open flow rate. The valve body 1 includes a valve body 12 assembled inside a main body 10 and a main shaft 13 threaded into the main body 10 in a lifting motion, separating the valve body 12 from the valve seat 14. A handle 2 is mounted above the valve body 1 for manually rotating the main shaft 13. Near the upper part of the valve body 1, a fully open position adjustment mechanism 20 is provided. This mechanism restricts the rotation of the handle 2 on the fully open side, setting the upper limit of the flow rate of the valve body 12 when fully open.

This invention relates to the field of precision measurement technology, and more particularly to a precision mechanism alignment device. The precision mechanism alignment device includes a frame, an upper alignment mechanism, a lower alignment mechanism, and a coarse alignment mechanism. The lower alignment mechanism includes a first support, a roller assembly, and a micrometer adjustment assembly. The first support is mounted on the frame, and the micrometer adjustment assembly is mounted on the first support and connected to the roller assembly. The micrometer adjustment assembly is configured to adjust the horizontal level of the roller assembly in the height direction. The upper alignment mechanism includes a second support, a vision component, and a leveling bolt. The second support is slidably mounted on the frame in the height direction, and the vision component is mounted on the second support. The vision component is configured to detect the horizontal angle of the second support. The leveling bolt is mounted at the bottom of the second support. The coarse alignment mechanism is mounted at the top of the first support. The leveling bolt can abut against the coarse alignment mechanism, enabling precise adjustment and reducing errors, thereby achieving accurate alignment and facilitating operation.

The invention discloses a non-contact vibration isolation positioning method and device, belongs to the technical field of vibration isolation, and is used for solving the problems that a contact positioning valve of a vibration reduction and isolation platform transmits external vibration and has small-amplitude oscillation. The non-contact vibration isolation positioning method comprises the steps that a control system obtains height data of an equipment platform through a distance measuring sensor in real time, and when it is judged that the height of the equipment platform deviates from a preset height, an action instruction is sent to an execution unit; and the execution unit executes the action instruction, so that a valve switch of the positioning valve is limited at the inflation and deflation positions, the air spring is inflated or deflated, and the equipment platform is adjusted to the preset height. According to the non-contact vibration isolation positioning method and device, the effect of preventing external vibration from being transmitted to the equipment platform is achieved, and the vibration reduction and isolation performance and reliability are improved.
