Problems solved by technology

The magnetic switch solves the trouble of repeatedly dismantling the sealing end cover with a manual switch, avoids the situation of slippage in the threaded hole of the fixed sealing end cover on the shell, and the situation of sparks threatening personal safety when the power is turned on and off, and improves the self-efficacy. The convenience and reliability of the power on and off of the lower robot effectively solve the problems existing in the power on and off of the sealed manual switch

Embodiment 1

[0028] Such as Figure 1~6 and Figure 8 As shown, the present invention includes a loam cake 1, a base 2, a contact 3, an elastic component, a connector 7 and a bar magnet 11, wherein the base 2 is installed on the body 6 of an autonomous underwater robot through a screw 12, and is connected by an O-shaped The sealing ring 4 is sealed to ensure the tightness of the magnetic switch and the body 6; different bases 2 can be designed for different shapes of the body 6, and the base 2 of the present embodiment is in the shape of a disc, with accommodating connectors 7 and 6 in the middle. Cavities for elastic components. The upper cover 1 is disc-shaped, fixedly connected to the base 2 by screws 12, and the upper cover 1 and the base 2 are also sealed by an O-ring 4 to ensure the sealing of the magnetic switch. The connecting piece 7 is cylindrical and accommodated in the cavity in the base 2 . The upper and lower ends of the connecting piece 7 are respectively provided with U-s...

Embodiment 2

[0033] Such as Figure 7 As shown, the difference between the present embodiment and the first embodiment is that there is a groove on the connector 7 of the present embodiment, and the steel sheet 8 is replaced by a magnet 20; 7 is fixed, and magnet 20 and copper sheet 9 are cuboid shape. The lower surface of the upper cover 1 is provided with a convex body B15, which has a hole 18 in the middle of the convex body B15, and the upper surface of the connector 7 is provided with a guide post 19 inserted into the hole 18, and the two ends of the spring 5 are respectively sleeved on the convex body. On the B15 and the guide post 19, when the bar magnet 11 attracts the magnet 20, the guide post 19 moves up and down in the hole 18 to play a guiding role. Others are all the same as in Embodiment 1.

[0034] Working principle of the present invention is:

[0035] When the autonomous underwater robot needs to be powered on land or in water, the staff put the bar magnet 11 close to t...

Abstract

The invention relates to a magnetic switch for powering on and off of an autonomous underwater vehicle (AUV). A base is hermetically installed on a machine body of the AUV, an upper cover is in sealedconnection with the base, the two ends of a connecting piece are respectively provided with magnetic pieces and conductive pieces, and an elastic part is arranged between the connecting piece and theupper cover. Grooves for installing a contact or a convex body A are formed in the internal of the base respectively, and the magnetic piece at one end of the connecting piece is attracted and rotated by a bar-shaped magnet positioned outside the upper cover through the magnetic force with the upper cover positioned in between. The connecting piece is driven to rotate between the groove for installing the contact and the groove for installing the convex body A through the bar-shaped magnet. The connecting piece falls into the groove for installing the contact after the bar-shaped magnet is removed, and the conductive pieces contact with the contact to realize closing and connecting of the internal circuit of the machine body, or the connecting piece falls into the groove for installing the convex body A to realize disconnection of the internal circuit. The magnetic switch has the advantages of being simple in structure, convenient for operation, good in sealing performance and small in occupied space, frequent operation and the like can be achieved, and the service lifetime of the magnetic switch and the life of the machine body can be prolonged. The magnetic switch can be widelyapplied to various underwater devices.

Description

technical field [0001] The invention relates to a sealed magnetic switch mainly used in a liquid environment, in particular to a magnetic switch used for power on and off of an autonomous underwater robot. Background technique [0002] With the development of high and new technologies such as microelectronics, computers, artificial intelligence and compact energy, as well as the needs of marine engineering and military, autonomous underwater robots have developed rapidly. Autonomous underwater robots are underwater devices that rely on their own energy to complete related tasks. Due to the particularity of the working environment of underwater robots, the requirements for sealing performance are usually high. At present, the underwater robot usually uses a manual switch to power on and off the underwater robot, and the switch is sealed through a sealing end cover, and the sealing end cover is usually fixed to the body by screws. It is necessary to open the sealing end cap ...
