Abstract

PURPOSE:To easily float a device by high pressure air with simple constitution, by providing a valve operated through a valve opening signal and a valve operated through a lever connected to a weight for supply of air in a dividing main unit having a seawater circulative port in the bottom part. CONSTITUTION:If landing on the water is performed from a seawater circulative port 4 provided to the bottom part of a diving main unit 3, seawater enters the unit 3 and a diving device is lowered, then if the seawater is contacted with a vent valve device 15, the device is automatically closed and release of air in the unit 3 is prevented. If the diving device is seated to the sea bottom 9, also a weight 31 is seated and a control rod 26 is lifted to open a valve 24. If a floating instruction signal is generated, a receiver 13 receives the signal, and a valve 36 is selected while a valve 23 is opened, then high pressure air in a cylinder 2 is jetted to an upper part in the unit 3 via a supply pipe 21, and the diving device is started floating, here the valve 24 is closed by the weight 31 through the rod 26, in this way, supply of air is prevented and the diving device is slowly floated.

Description

[Detailed description of the invention] , The present invention relates to a flotation device for an unmanned underwater diving device.

In recent years, diving devices have been placed on the bottom of the deep sea to explore deep seabed resources, store food on the deep seabed, conduct experiments under high pressure, build communication bases on the deep seabed, and detect earthquakes. The idea is to let it stay there for a long time and then float it up again. Submarines and deep-sea exploration boats have problems in that their flotation devices, which allow them to rise from the ground, are complex, expensive, and consume a lot of energy.

Therefore, the present invention provides a flotation device for an unmanned diving device that solves these problems, and its features include a closed shell-like diving body with a seawater flow port formed at the bottom; An air supply pipe is provided which is connected to a high pressure air cylinder and whose other end opening is located at the upper part of the submersible body. A second on-off valve is provided, a first on-off valve control device is provided which operates in response to a valve opening signal to open the first on-off valve, and a lever is provided protruding from the valve body of the second on-off valve, and the lever opens the valve. A spring is provided that adjusts the direction, and is connected to the lever, and when the submersible main body touches the bottom, it also touches the bottom and allows the second on-off valve to be opened by the spring, and the submersible main body floats up. When this happens, a weight is provided that moves the lever in the valve closing direction against the spring due to its own weight.With this configuration, the configuration is simple and inexpensive, and a valve opening signal is generated to close the first opening/closing valve. It can be easily levitated using high-pressure air by simply opening the holder, and energy consumption is low.

Limit switch 4 is also turned off. As the unmanned diving device descends, the water pressure rises and the air inside the submersible body (3) contracts.Then, the water surface inside the submersible body (3) reaches the third level as shown by (H, W, L). When the electrode is contacted, both three-way switching 'I

Enter the open side chamber and open both on-off valves (231(2). This allows the high-pressure air in the d-pressure air cylinder to flow through the second air supply pipe and the check valve (2). The water is ejected to the upper part of the main body (3), and the water level inside the submersible main body (3) is lowered, and the water surface is connected to the second electrode ←9 as shown in (N, W, L) in Figure 3.

When the unmanned diving device touches the bottom of the deep ocean (9), the weight button also touches the bottom, the operating rod is raised by the spring (in the direction of arrow A), and the second on-off valve is raised via the lever. It will be released. Also, the limit switch 0υ is turned on by the kickboard, and the signal causes both three-way cuts 4!
/! ', the magnetic valve (3 (to) (39)) is switched to close both opening/closing valves +231 C34. In such a state, if the unmanned diving device remains on the deep seabed (9) for a long period of time and the unmanned diving device is desired to be retrieved next time, a floating command signal may be issued toward the seabed. Then, the signal receiving and transmitting device Nishiki receives the command signal, and the 1n control device that receives the signal! lI The first three-way switching valve (direct solenoid valve) is switched, and the first on-off valve (to)
will be released. Then, the high-pressure air in the high-pressure air cylinder (Nonouchi) is blown out to the upper part of the submersible body (3) through the first air supply pipe (21) and the check valve (2), and the water device starts to ascend. When the diving equipment fiffi surfaced a little,
