Description

Technical Field

[0001] The utility model belongs to the technical field of marine search and rescue equipment, and in particular relates to a marine search and rescue device for people falling into water. Background Art

[0002] With the booming development of maritime trade and shipping, maritime distress accidents occur frequently, posing new challenges to the maritime search and rescue capabilities of various countries. Existing overboard alarm and search and rescue products, such as Beidou flare TD10, are mainly location transmission and alarm terminals based on the Beidou system. The problem with such products is that they need to be equipped with an independent power supply, so their endurance is weak and it is difficult to ensure long-term continuous operation in certain extreme situations, reducing the chances of the victims being rescued. Therefore, how to develop a new search and rescue device for people who fall into the water at sea to overcome the above problems is a direction that technicians in this field need to further study. Utility Model Content

[0003] The purpose of the utility model is to provide a search and rescue device for people who fall into water at sea, which can realize long-term power supply to the position transmission and alarm terminal, improve its endurance, and increase the probability of rescue of people in distress at sea.

The positioning device generates and outputs spatial coordinates when powered on, and the alarm device generates and outputs alarm signals when powered on. To achieve positioning guidance for maritime rescue. This solution does not need to rely on an independent power supply, so it has a strong endurance. At the same time, compared with the photovoltaic panel method, it does not need to rely on solar energy and can be powered in bad weather such as rainy days and cloudy days.

[0009] Preferably, the search and rescue device further comprises: a light emitting device, which is electrically connected to the power supply device and is used to emit light when entering a power-on state; and the power supply device is also used to supply power to the light emitting device.

[0010] By adopting this technical solution, when a shipwreck occurs, the light-emitting device can emit light to call for help under the action of the power supply device, thereby further improving the chance of the victims being rescued in a night environment.

[0014] Preferably, the Beidou locator and the Beidou alarm are integrated and installed in Beidou Yitong E-198B; the AIS locator adopts Feitong FT-501; and the AIS alarm adopts Zerun H10.

[0015] Compared with the prior art, the utility model has achieved the following technical advances:

DETAILED DESCRIPTION

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] Example 1, please refer to Figure 1-3 :

[0026] A device for searching and rescuing people who fall into water at sea comprises: a power supply device 100, a light emitting device 200, a positioning device 300 and an alarm device 400.

[0027] The power supply device 100 is electrically connected to the positioning device 300, the alarm device 400 and the light emitting device 200 respectively, and is used to supply power to the positioning device 300, the alarm device 400 and the light emitting device 200. The power supply device 100 includes a tactile hydrogel sensor, which is a flexible plate structure.

[0028] Specifically, the hydrogel sensor includes: a laminated polydimethylsiloxane layer 130110, a first hydrogel layer 120, a polydimethylsiloxane layer 130 and a second hydrogel layer 140. The upper side of the laminated polydimethylsiloxane layer 130110 is fixedly connected to the lower side of the first hydrogel layer 120 as a whole, the polydimethylsiloxane layer 130 covering the upper side of the first hydrogel layer 120, and the second hydrogel layer 140 covering the upper side of the polydimethylsiloxane layer 130, wherein the upper side of the polydimethylsiloxane layer 130 is distributed with polydimethylsiloxane conical protrusions 131 extending toward the second hydrogel layer 140; the lower side of the second hydrogel layer 140 is distributed with hydrogel conical protrusions 141 extending toward the polydimethylsiloxane layer 130.

[0029] The positioning device 300 is further configured to be installed on the upper side of the tactile hydrogel sensor, and the positioning device 300 is used to generate and output spatial coordinates. The alarm device 400 is further configured to be installed on the upper side of the tactile hydrogel sensor, and the alarm device 400 is used to generate and output an alarm signal. The light-emitting device 200 adopts a flexible light-emitting board and is covered and installed on the upper side of the tactile hydrogel sensor. The flexible light-emitting board is used to continuously emit light when powered on. The flexible light-emitting board can adopt a flexible LED soft strip light.

[0030] In this example: the positioning device 300 includes a Beidou locator and an AIS locator. The alarm device 400 includes a Beidou alarm and an AIS alarm. The Beidou locator and the Beidou alarm are further integrated into Beidou Yitong E-198B; the AIS locator uses Feitong FT-501; and the AIS alarm uses Zerun H10.

[0031] In practice, the working process is as follows:

[0032] When a shipwreck occurs, the victims lay the hydrogel sensor flat and soak it in seawater. Since the hydrogel sensor is light in weight, it can be laid flat on the sea surface by buoyancy. At the same time, the constantly surging waves will drive the hydrogel sensor to continuously bend, twist and stretch. During this process, the upper side of the polydimethylsiloxane layer 130 and the lower side of the second hydrogel layer 140 continue to collide and rub. Since there is a difference in the electron attraction ability of the polydimethylsiloxane layer 130 and the second hydrogel layer 140, a continuous directional current will be generated between the polydimethylsiloxane layer 130 and the second hydrogel layer 140 during the continuous collision and friction process. The directional current can be used to power the positioning device 300, the alarm device 400, and the light-emitting device 200. The positioning device 300 is used to generate and output spatial coordinates in real time when powered on. The alarm device 400 is used to generate and output alarm signals in real time when powered on. The light-emitting device 200 is used to continuously emit light when powered on. This ensures that the positioning device 300, the alarm device 400, and the lighting device 200 can work for a long time, and overcomes the shortcomings of the battery life of existing similar products.
