Underwater butt joint device for water intake and discharge culvert of thermal power plant

This utility model discloses an underwater docking device for intake and drainage box culverts in thermal power plants. It includes a precast box culvert with water-stopping mechanisms evenly distributed around its ends, and symmetrically embedded tie rod brackets on both sides. The top of the precast box culvert has lifting points, and the bottom has embedded steel plates. A tie-fitting seat is installed on the top of the precast box culvert. The tie rod brackets are bolted to reinforcing tie rod bolts to secure adjacent precast box culverts. Adjacent precast box culverts are connected to the tie-fitting seat via jacks and tie rods. The jacks and tie rods, in conjunction with the jacks, adjust the spacing between adjacent precast box culverts. This utility model, by setting a tie-fitting seat and tie rod brackets on the top of the precast box culvert, and using designed jacks and jacks and tie rods to dock two precast box culvert sections, ensures that the two sections are precisely aligned to the latest design spacing, guaranteeing that the sealing of the precast box culvert interface meets design requirements, thereby ensuring the water quality of the circulating water system.

Liquid connector

ActiveCN224433714UOvercome prone deflectionsovercoming misalignmentStructural engineeringUnderwater docking
This utility model discloses a liquid connector, which includes a female connector, a male connector, and a gasket. One end of the male connector is installed with the female connector. The outer wall of the male connector has an adjusting ring surface that surrounds it, and the adjusting ring surface is a convex arc surface that protrudes outward. The gasket is sleeved on the male connector, and the inner wall of the gasket has a mating surface that mates with the adjusting ring surface. The gasket has a first state and a second state. In the first state, the mating surface abuts against the adjusting ring surface at a first contact position, so that the male connector maintains a first angle. In the second state, the mating surface abuts against the adjusting ring surface at a second contact position different from the first contact position, so that the male connector maintains a second angle different from the first angle. Through the design of the guide sleeve, the problem of misalignment and displacement that easily occurs when the male and female connectors are docked underwater is effectively overcome, and the convenience and success rate of the docking operation of the male and female connectors are significantly improved.

An underwater docking device with power transmission capability and a docking method thereof

ActiveCN120709768BStructural engineeringUnderwater docking
This invention discloses an underwater docking device and method with power transmission capability. It includes a male connector and a female connector base. In the male connector: a mounting shaft, an electromagnet mounting bracket, and an underwater electromagnet are coaxially arranged on the male connector mounting base. A male angled iron core mounting seat is fitted outside the mounting shaft and is connected to the male connector mounting base via a spring. Several male angled iron cores are mounted on the male connector angled iron core mounting seat, each with a primary insulated magnetic wire winding. In the female connector base: several female angled iron cores are connected between the female connector base mounting base and an external guide component, each with a secondary insulated magnetic wire winding. This invention, by combining a floating support structure and a composite guiding structure, achieves precise coordination of adaptive position correction and magnetic circuit closure between the male connector and the female connector base during underwater docking.

Six-degree-of-freedom full-attitude active docking device for deep-sea underwater vehicle

PendingCN122101445AVessel salvagingUnderwater equipmentMarine engineeringUnderwater docking
The application relates to the technical field of underwater docking of a vehicle, and discloses a deep-sea underwater vehicle full-attitude active docking device which comprises a main frame arranged on a bottom plate, a vehicle carrier arranged on the main frame and located above an adjusting base, wherein the vehicle can travel along an x-axis direction to above the vehicle carrier and sink onto the vehicle carrier; when the vehicle sinks onto the vehicle carrier, the vehicle carrier generates an unbalanced force which can drive the vehicle carrier to move along a y-axis direction and a z-axis direction; when the vehicle carrier is balanced, the front end of the vehicle corresponds to a positioning column, and the tail end of the vehicle corresponds to the upper surface of a guide positioning column; an adjusting cylinder is used for driving the guide positioning column to rotate and adjusting the vertical distance between the upper surface of the guide positioning column and the bottom plate. The positioning structure is simple in structure, small in size, can be adapted to the carrying and docking requirements of small-sized underwater vehicles, and can realize multi-degree-of-freedom pose adjustment and improve the docking positioning precision.
