Embodiment 1

[0018] Such as figure 1 , the present invention is a forecast and alarm device for rip current, the device is placed in the area where rip current occurs frequently, and the wind power generation device provides power guarantee for the whole set of equipment. In the calm state of the ocean, there is not much difference between the flows measured by the first and second spinner current meters, and the controller will not be triggered; in the case of rip currents, there will be a The difference, so the controller will trigger the paint box and the horn, spread red non-polluting paint and play the broadcast of the rip current, and if the difference exceeds 1, it will trigger the paint box one or two at the same time, and spread more red paint , to make a more obvious warning to the outside world.

[0019] A rip current forecasting and alarming device, comprising a fixing device, a rip current detection device, a rip current alarm device, and a wind power generation device, compr...

Embodiment 2

[0025] The present invention designs an offshore current forecast and alarm device, which is mainly composed of a rotary cup flow meter, a processor, a non-polluting paint, a dispenser, a horn, a wind power generation device and the like. When the rip current occurs, the current speed measuring device measures the difference in velocity between the area where the rip current occurs and the area where the rip current does not occur, and judges whether the rip current occurs. When it is determined that a rip current is in danger in this area, the dispenser opens and spreads red non-polluting paint to warn swimmers, swim out of the area where the rip current occurs in time along the direction perpendicular to the rip current, and let the Rescuers discovered the disaster in the area in time and raised their attention to the area. At the same time, turn on the loudspeaker to play the recording of the rip current here, to remind swimmers who did not see the red paint in time to evac...

Abstract

A rip current prediction and alarm device belongs to the field of ocean safety early warning, and comprises a fixing plate and a wind power generation device; wherein the wind power generation devicecomprises a wind wheel and a tower, the wind wheel is arranged at the top of the tower; the bottom of the tower is fixed on the fixing plate; the tower is provided with a first current meter; a loudspeaker and a data processing and control module are arranged over the fixing plate; a fixing device and a paint box are arranged under the fixing plate; and the data processing and control module is connected with the loudspeaker, the first current meter and the paint box separately through lines. The rip current prediction and alarm device of the invention is sensitive in measurement, convenient in use, and capable of timely discovering the occurrence of a rip current and giving warning, in addition, the rip current prediction and alarm device has a good warning effect by adopting various modes such as red pigment indication and loudspeaker broadcast, so as to guide a swimmer to escape in time and guide a lifeguard to perform rescue in time.

Description

technical field [0001] The invention belongs to the field of marine safety early warning, and in particular relates to an offshore current forecast and alarm device. Background technique [0002] The rip current is a strip-shaped surface flow that, under the action of the radiation stress and pressure difference of the sea surface waves, breaks the waves and accumulates them to the shore, and then passes through the broken wave belt and flows back into the sea. Its flow velocity is relatively high, and it can transport the sediment suspended by the breaking wave and the material discharged along the coast to the outside of the breaking wave zone. Most of the rip currents have a velocity of 1m / s, and the fastest can reach 3m / s, which can quickly drag strong swimmers into deep water and cause drowning. [0003] Rip currents have become another marine disaster that harms people's seaside tourism after storm surges. About 90% of seaside drownings are caused by rip currents, wh...
