Description

  The present invention relates to a portable radar reflecting device for the purpose of allowing a ship, a rescue ship, and a rescue team passing through the vicinity to easily find the position of a person who has fallen in the event of a marine accident.

Japan is surrounded by the sea, and the operation of ships plays an important role. However, due to the rise of the leisure industry in recent years, the number of small ships has increased, and the number of waterfall accidents from these small ships has increased. . Moreover, there are no end to accidents caused by waterfalls in lakes and rivers. In such an accident, when a person is thrown out of the ship, it is difficult to identify the location of the person who has fallen into the water during the rescue. There was a problem that led to a fatal accident. As a solution to this problem, there is a radar reflection device. However, the conventional radar reflection device is so large that it cannot be carried at all times. There is a problem that it is not practically useful in an emergency because it is impossible.

The first embodiment will be described with reference to FIG.

  The first embodiment is a portable radar reflection device 0101 including a high-pressure gas cylinder unit 0102, a gas release switch unit 0103, a support column unit 0104, and a reflection unit 0105.

    <Description of Configuration of Embodiment 1>

  The “high pressure gas cylinder part” encloses and holds the high pressure gas in the cylinder. The high-pressure gas is nitrogen gas, carbon dioxide gas, inert gas (argon gas, helium gas, etc.), air, or the like. In addition, a gas generator (inflator) used for airbags may be used. The cylinder is made of a material such as metal or resin. For example, an iron plate or copper plate subjected to anticorrosion plating or painting, aluminum, aluminum alloy, stainless steel, titanium, titanium alloy, reinforced plastic, glass fiber, or carbon fiber may be used alone or in combination.

  The “gas release switch part” refers to a part for releasing the high-pressure gas press-fitted into the high-pressure gas cylinder part. For example, in order to detect the water pressure or the landing of water and to release the gas in the high-pressure gas cylinder part, the specification may be such that the stopper of the cylinder is opened or a structure with a hole may be used. At that time, a pressure valve made of pulp that is torn by water may be used, or a valve that can be electrically opened using an electronic circuit that senses water may be used.

  The “support part” is expanded by the high-pressure gas released by the gas release switch part and becomes a hollow support. The high-pressure gas is sealed and held in a high-pressure gas cylinder.

  The “reflecting part” is arranged at the tip of the column part, is opened by the opening switch, is expanded by the gas introduced through the column part, and can reflect the radar wave. The outer surface itself that is in contact with the atmosphere may reflect the radar wave, or the outer surface itself may not reflect the radar wave but may reflect the radar wave by the internal structure of the reflecting unit. good. In the former case, the outer surface itself is made of a material that reflects radar waves, and in the latter case, a material that reflects the radar waves is used for the internal structure.

  The height of the present embodiment is, for example, a height of 100 cm. The pressure in the high pressure gas cylinder is 0.5 Nm3 (normally bay). The reflection part is developed by the process shown in FIG. After deployment, the radar reflector does not roll over and can be recognized by the radar device.

  The structure of the reflector means is preferably a structure that reflects radar waves efficiently. For example, in a cylindrical radar reflector, a three-dimensional structure having a diameter Lm of 4 cm or more and 100 cm or less efficiently reflects radar waves. When the distance is less than 4 cm, the incident radar wave and the reflected radar wave cancel each other, and a good reflection characteristic cannot be obtained. When it exceeds 100 cm, the non-reflection radar wave increases and the good reflection characteristic is obtained. I can't get it. And since a reflecting plate means is substantially inscribed in the inner wall of a reflecting part, it becomes a structure where a reflecting plate expand | deploys as a reflecting part expand | swells with the gas from a high pressure gas cylinder part.
