Underwater laser and toy battleship

Abstract

The invention provides an underwater laser which comprises a laser emitter and an ultrasonic wave emitter, wherein a wave guide tube is arranged in front of the ultrasonic emitter; the wave guide tube is used for emitting out ultrasonic wave along a straight line in a single direction; a laser beam generated from the laser is emitted out along a straight line; the power of the ultrasonic wave generated from the ultrasonic wave emitter can achieve an cavitation effect on a water body. The underwater laser can generate clear and visible laser beam under water of any quality, and then working needing yardstick positioning is facilitated.

Description

Technical field [0001] The present invention relates to the field of lighting, in particular, to the field of underwater laser lighting. Background technique [0002] For lasers, because of its good directivity, it is widely used in positioning. However, when the laser is used for positioning during the day, if there is no intermediate medium, due to the strong ambient light, only one spot on the surface of the object irradiated by the laser can be seen, and the laser beam cannot be seen, which makes it necessary to follow a straight line The work of the homework is more difficult to operate, and it still needs to be supplemented with tangible guidelines as a reference. [0003] In particular, for some underwater operations, such as pool maintenance, etc., it is necessary to arrange underwater guide lines, and because the water quality of some pools is relatively clean, such as swimming pools or purification pools, then when laser positioning is used, the laser beam directly penet...

Problems solved by technology

However, when the laser is used for positioning during the day, if there is no intermediate medium, due to the strong ambient light, only a spot of light on the surface of the object irradiated by the laser can be seen, but the laser beam cannot be seen, which makes some objects need to be positioned along a straight line. The work of the homework is difficult to operate, and it still needs to be supplemented by tangible guidelines as a reference

[0003] In particular, for some underwater operations, such as pool maintenance, etc., it is necessary to arrange underwater guidelines, and because the water quality of some pools is relatively clean, such as swimming pools, or purified pools, then when lasers are used for positioning, the laser beam directly penetrates the water body , the beam is still invisible to the naked eye, and it is still inconvenient for underwater operations

[0004] It can be seen that the current laser is difficult to form a positioning guideline in clean water
