Deep-sea non-contact electric power transmission packaging structure

Abstract

The invention discloses a deep-sea non-contact electric power transmission packaging structure. By using the prior art, a deep-sea severe environment can not be coped with and robot operation can not be performed conveniently under the sea. The packaging structure of the invention comprises: a primary coupling joint and a secondary coupling joint. The primary coupling joint is designed with a magnetic core cavity, a control cavity and a card hook groove. The secondary coupling joint is designed with the magnetic core cavity, the control cavity, a guide plate and a card hook mechanism. Primary and secondary docking mechanisms are arranged out of the two joints. After the primary coupling joint and the secondary coupling joint form a coaxial docking, magnetic cores in the two left and right magnetic core cavities of contact surfaces are correctly coupled with each other and electric power is transmitted. After the transmission ends, the docking mechanisms break. In the invention, a reasonable sealing structure is designed. A waterproof connector is connected with an underwater cable. The deep-sea extreme environment, such as a high pressure and strong corrosion can be coped with. The structure is stable and reliable. The internal system is not easy to be influenced by seawater disturbance. A plugging form is simple. The underwater robot is very suitable for the docking operation. A service life is long.

Description

technical field [0001] The invention belongs to the technical field of deep-sea electromechanical packaging, and relates to a packaging structure that satisfies non-contact power transmission in deep-sea environments and is suitable for underwater robot operations. Background technique [0002] There are mainly two ways to connect power transmission cables in the deep sea: contact type and non-contact type. The contact type is the so-called wet plug connector, which still realizes the cable connection through the mutual contact between the conductors. This type of connector is expensive. The service life is short, and underwater robots are required to perform complex plug-in operations, which is difficult to realize; while using the principle of electromagnetic induction, the non-contact transmission of electric energy is realized. The Chinese patent underwater electric energy transmission non-contact connection device (public number CN 101667778A) and the non-contact co...

[0002] There are mainly two ways to connect power transmission cables in the deep sea: contact type and non-contact type. The contact type is the so-called wet plug connector, which still realizes the cable connection through the mutual contact between the conductors. This type of connector is expensive. The service life is short, and underwater robots are required to perform complex plug-in operations, which is difficult to realize; while using the principle of electromagnetic induction, the non-contact transmission of electric energy is realized. The Chinese patent underwater electric energy transmission non-contact connection device (public number CN 101667778A) and the non-contact connection device for underwater power and signal transmission (public number CN 101667777A) realize the non-contact transmission of power and electric signals. Because of the non-contact, this power transmission method has high reliability and long service life , but the above patents did not study in depth the reliable external packaging to deal with the harsh environment of the deep sea and how to facilitate the operation of underwater robots
