Downhole wireless charging mechanical device

The invention discloses a downhole wireless charging mechanical device, and belongs to the field of petroleum. The downhole wireless charging mechanical device comprises a downhole charging short section device and a cable carry charging device, wherein the downhole charging short section device and the cable carry charging device are respectively independent. In the charging process, the cable carry charging device is installed inside the downhole charging short section device, the cable carry charging device is coupled to the downhole charging short section device, and then the downhole charging short section device can be charged. By the adoption of the design that the cable carry charging device and the downhole charging short section device are coupled, the downhole wireless charging function is achieved, electric energy is provided for an instrument which is lingered downhole for a long time, test deployment and dynamic monitoring tasks of the downhole instrument are completed, battery replacement operation of the downhole instrument is omitted, and test deployment efficiency is improved. In addition, the downhole wireless charging mechanical device is simple in operation, operation of professional staff is not needed, and the downhole wireless charging mechanical device is convenient to popularize and use on the scene.
