Going up mobile magnetic core mechanism comprises: go up dish, first FERRITE CORE that constitutes by disk and newel, striker and secondary coil, one side of striker has center bolt, there is the guiding oblique angle on the opposite side top, the center bolt of striker passes the centre bore that is opened in first FERRITE CORE and last dish successively, stretch out stubborn first nut that is connected to of center nose end at screw rod, the newel plane and the striker of first FERRITE CORE are close to, between the last dish and first nut, first spring shim is arranged, secondary coil is enclosed within on the newel of first FERRITE CORE, and the disk of first FERRITE CORE has two symmetric windows, is butterfly-like;
Following fixed magnetic core mechanism comprises: lower wall, second FERRITE CORE that constitutes by disk and newel, the cylinder and the primary coil at the band end, center bolt is arranged at the bottom of cylinder, this center bolt passes the centre bore that is opened in second FERRITE CORE and lower wall successively, stretch out stubborn second nut that is connected to of center nose end at screw rod, the newel plane of second FERRITE CORE and the bottom surface of cylinder are close to, between the lower wall and second nut, second spring shim is arranged, primary coil is enclosed within on the newel of second FERRITE CORE, be built-in with cushion pad at cylinder, the disk of second FERRITE CORE has two symmetric windows, is butterfly-like.
Operation principle:
The separable transformer primary coil is connected with supply unit, and secondary coil links to each other with power consumption equipment.When the needs electric energy transmitting, will go up mobile magnetic core mechanism and be coaxial docking with following fixed magnetic core mechanism, the striker that has the oblique angle that leads of going up mobile magnetic core mechanism slips into down in the band round-ended cylinder of fixed magnetic core mechanism, the aligning automatically of assurance separable transformer; Cushion pad in the cylinder can avoid separate transformers to be subjected to too fierce impact; By striker length and cushion pad thickness the end play of two magnetic cores is fixed, prevent the circuit parameter variations of separable transformer; Form stable electromagnetic coupled between primary coil and secondary coil.When feeding high-frequency alternating current in the primary coil, secondary coil can receive electric energy effectively, uses for load.After charging was finished, last travel mechanism moved upward, and striker skids off cylinder, can finish the separation of separable transformer, and power consumption equipment can move voluntarily.
The beneficial effects of the utility model:
The electromagnetic coupled structure that adopts the utility model realizes the transmission of underwater electric energy, the physics contact of the interface of avoiding transmitting electricity and being electrically connected; Still can keep electromagnetic coupled preferably when having guaranteed that by the butterfly magnetic core that has newel there are big gap in the former limit of separable transformer, secondary coil; Because allow to have big gap between the circle of former and deputy sideline, the difficult foreign material that dropped to the transformer surface scratch; All there are not cavity in the last mobile magnetic core mechanism of separable transformer of the present utility model and following fixed magnetic core mechanism, and inside and outside pressing is weighed, and can bear deep-sea high pressure effect; Simple in structure, withstand voltage, good airproof performance, the reliability height, easy to maintenance, effectively solve the fail safe of submarine transmission interface and the shortcoming that involves great expense.By verification experimental verification, the utility model can be in the efficiency of transmission than realization about 92% under the broad gap of 10mm.
