Anti-pressure position indicator for marine equipment

Abstract

The invention discloses an anti-pressure position indicator for marine equipment. The anti-pressure position indicator for the marine equipment comprises a base, an upper cover and a display rod, the upper end of the base is fixedly connected with the lower end of the upper cover, and a threaded foundation support is vertically mounted at the upper end of a threaded base, one end of the display rod penetrates through the upper cover and a mounting plate simultaneously and is located in the base, an outer thread is arranged on the outer side of one end of the display rod, and a threaded connecting cavity is formed in the end portion of one end of the display rod; the threaded base is connected into the threaded connecting cavity through threads, therefore the pressure of seawater applied on the base and the upper cover can be effectively relieved, the protection effort on a GPS locator, a single chip microcomputer, a power source and the like can further be strengthened, so that the service life of the position indicator is greatly prolonged, the position indicator is prevented from deforming under the impact of water, the phenomena of avulsion and damage of the position indicator are avoided, the machining technology is simple, the machining accuracy is low, the cost is low and machining is easy to achieve.

Description

technical field [0001] The invention relates to the technical field of marine equipment, in particular to a pressure-resistant position indicator for marine equipment. Background technique [0002] At present, the common marine equipment that needs positioning generally has its own GPS and Iridium equipment to send the location information to the mother ship or the control center. However, when the marine equipment fails to surface or the GPS and Iridium equipment fails, When the location information cannot be sent out, the marine equipment will often be lost, such as underwater submersible buoys and AUV equipment for long-term monitoring of marine information. Position indicators are widely used as navigation buoys on water or as fishing and breeding tools. Most of the currently used position indicators have a smooth surface. During the impact of the water flow, the position indicator has little resistance against the water body and is easy to drift. In addition, the water...

[0002] At present, the common marine equipment that needs positioning generally has its own GPS and Iridium equipment to send the location information to the mother ship or the control center. However, when the marine equipment fails to surface or the GPS and Iridium equipment fails, When the location information cannot be sent out, the marine equipment will often be lost, such as underwater submersible buoys and AUV equipment for long-term monitoring of marine information. Position indicators are widely used as navigation buoys on water or as fishing and breeding tools

The surface of the currently used position indicator is mostly smooth structure. During the impact of the water flow, the position indicator has little resistance against the water body and is easy to drift

In addition, the water flow directly impacts the surface of the position indicator, which will seriously damage the position indicator, and even cause tearing and damage of the position indicator, which will affect its normal function and use.
