Induction type underwater switch

Abstract

The invention discloses an induction type underwater switch which comprises a handle, a handle lifting pull shaft, a pressure spring, a cover plate, a rotor fixing ring, a pressure-resistant shell, arotor, a Hall sensor proximity switch and a strong magnet. The rotor is arranged in the pressure-resistant shell; the upper and lower parts of the rotor are respectively supported in the pressure-resistant shell through bearings; the rotor fixing ring is fixed at the upper end of the pressure-resistant shell; the cover plate is fixed at the upper end of the rotor; a mounting hole is formed in theupper end of the rotor, the lower end of the handle lifting pull shaft is arranged in the mounting hole, and the upper end penetrates through the cover plate to be fixedly connected with the handle; apressure spring is arranged between the lower end of the handle lifting pull shaft and the cover plate; the cover plate and the rotor are sleeved by the handle, and the handle is supported on the rotor fixing ring; a meshing structure is arranged between the handle and the cover plate or the rotor; a strong magnet is fixed on the excircle of the rotor; at least one Hall sensor proximity switch isfixed to the outer wall of the pressure-resistant shell. At least one positioning structure is arranged between the rotor fixing ring and the handle, so that the strong magnet is over against one Hall sensor proximity switch. The device provided by the invention has multiple triggering functions and is high in reliability.

Description

technical field [0001] The invention belongs to the field of circuit switches, in particular to an inductive underwater switch. Background technique [0002] In recent years, with the development of national defense and the continuous development of underwater resources, marine development and underwater defense of islands and reefs have been designated as development priorities by the country. There are more and more various tasks to be performed in resource development. When they complete their tasks underwater, they need to use various underwater equipment such as positioning, navigation, detection and measurement. These underwater equipment need a power switch to control the equipment on and off, and a multi-function switch to operate the equipment. Compared with ordinary switches, deep-water switches need to have better water tightness to prevent short-circuit and burnout of equipment circuits due to water leakage at the switch. The existing underwater switches have t...

Problems solved by technology

Existing underwater switches have insufficient pressure resistance to varying degrees, can only be used in shallow water areas, have complex structures, and do not have universal applicability.

For example, an underwater switch disclosed in Chinese patent applications 200720173947.8 and 201910030804.9 can be directly operated and used underwater, but its structure is too complicated to be universally applicable
