This embodiment proposes a pneumatic wave energy powered submersible, as shown in Figures 1 and 2, including a spindle-shaped submersible body 1, and two ends of a Y-shaped armored photoelectric composite cable 16 installed on the submersible body 1 At both ends of the short axis, the third end of the Y-shaped armored photoelectric composite cable 16 is connected to one end of the vertical armored photoelectric composite cable 17, and the other end of the vertical armored photoelectric composite cable 17 is connected to the anchoring sinker 18 , a pneumatic loop power generation unit is installed inside the submersible body 1, and the plane of the pneumatic loop power generation unit is perpendicular to the short axis of the submersible body 1. In order to obtain the maximum installation space, the plane of the pneumatic loop power generation unit should also coincide with the long axis of the latent specimen body 1.

It should be noted that the spindle-shaped latent specimen body 1 can be approximately viewed as a horizontal ellipsoid or a polyhedral prism. The horizontal position referred to here is not a horizontal position in an absolute sense, but is a stabilization of its normal working process. The position should be horizontal. Taking an ellipsoid as an example, the axis formed by its front and rear ends is the "minor axis" referred to above, and the axis formed by its left and right ends is the "major axis" referred to above. Its upper and lower ends are not within the design scope. within.

In addition, the submersible body 1 normally has 6 degrees of freedom motion modes in the ocean, including 3 translational degrees of freedom: sway, sway, and heave; and 3 rotational degrees of freedom, namely roll and pitch. Shake, bow shake. In this embodiment, the submersible body 1 is suspended in the sea water, and both ends of its short axis are fixed by the Y-shaped armored photoelectric composite cable 16, which limits the heaving, yaw, and roll of the submersible body 1. Movement, the long axis is not restricted, so the latent body 1 mainly uses its own surge and pitch motion to do work.

In this embodiment, the Y-shaped armored photoelectric composite cable 16 and the vertical armored photoelectric composite cable 17 are used as mooring chains to connect the submersible specimen body 1 and the anchoring sinker 18 on the seabed. Among them, the Y-shaped armored photoelectric composite cable 16 The two ends are used to fix the two ends of the short axis of the latent specimen body 1, which limits the heaving, yaw, and roll motions of the latent specimen body 1, while the surge and pitch motions are not affected, and The interior of the submersible body 1 is provided with a pneumatic loop power generation unit perpendicular to its short axis. Surface seawater waves are used to drive the sway or pitch motion of the submersible body 1, thereby driving the pneumatic loop power generation unit placed inside the submersible body 1. Pulsing or pitching works, and the aerodynamic energy conversion system generates electricity, realizing the in-situ self-power supply of the submersible buoy, greatly extending the working time of the submersible buoy in the ocean, and depending on the power generation, it can carry more ocean observation equipment , so that the power supply problem of the equipment on the latent bid can be solved. In addition, the pneumatic loop power generation unit is placed inside the submersible body 1, so it is less likely to be corroded by seawater and sea vapor, which increases the service life of the wave energy powered submersible energy conversion equipment.

In common application scenarios, the submersible body 1 is normally suspended in the sea water. Since the energy generated by the submersible body comes from wave energy, and the wave energy decreases with the increase of water depth, the distance between the submersible body 1 and the sea surface is It should not be too large, generally 1-2 meters is appropriate.

The above-mentioned pneumatic loop power generation unit can be any mechanism that uses pitching motion to generate electricity from the pneumatic energy conversion system. This embodiment proposes one of the preferred pneumatic loop power generation unit solutions. As shown in Figure 3, the pneumatic loop power generation unit The circuit power generation unit includes an annular tube 2. The upper part of the annular tube 2 is divided into a fifth air chamber 7. The left and right parts of the annular tube 2 are symmetrically divided into a first air chamber 3 and a second air chamber 4. The lower part of the annular tube 2 is divided into a liquid chamber. The first air chamber 3, the second air chamber 4 and the liquid chamber 8 are directly connected. The left and right ends of the fifth air chamber 7 are respectively provided with a second one-way valve 10 and a fourth one-way valve 12. The outlet ends of the directional valve 10 and the fourth one-way valve 12 are arranged back to each other. A passage is provided between the first air chamber 3 and the second air chamber 4 to form a third air chamber 5. The left and right ends of the third air chamber 5 A first one-way valve 9 and a third one-way valve 11 are provided respectively. The outlet ends of the first one-way valve 9 and the third one-way valve 11 are arranged opposite to each other. The third air chamber 5 and the fifth air chamber 7 are arranged between There is a passage forming a fourth air chamber 6. A pneumatic power generation component is arranged in the fourth air chamber 6. The bottom of the liquid chamber 8 is filled with liquid medium, and the level of the liquid medium does not exceed the level of the third air chamber 5. In this solution, four one-way valves work together to self-rectify the air in each air chamber.

Furthermore, the pneumatic power generation assembly includes a nozzle 14 installed in the middle of the fourth air chamber 6. The input end of the nozzle 14 faces the third air chamber 5. The output end of the nozzle 14 is connected to the air inlet end of the one-way impulse air turbine 15. The air outlet end of the one-way impulse air turbine 15 faces the fifth air chamber 7 , and the output shaft of the one-way impulse air turbine 15 is connected with the input shaft of the permanent magnet generator 13 . The pneumatic loop power generation unit disclosed in this embodiment has a simple structure and only has one unidirectional impulse air turbine 15 and a permanent magnet generator 13, which is easy to disassemble and maintain.

In some preferred embodiments, the liquid chamber 8 shrinks downward to form a trapezoid. When the liquid cavity shrinks into a trapezoidal shape, it not only causes the oscillating water column to move up and down to compress the air to do work when the submersible is pitching, but also compresses the air to do work during the surge.

In some preferred embodiments, the middle part of the fourth air chamber 6 expands toward both ends to form a trumpet shape. Expansion at both ends and contraction in the middle can accelerate the gas when it enters the pipe, making the impulse turbine start at a faster speed.

When the submersible body 1 performs a pitching motion under the action of waves, the bow is downward, as shown in Figure 4, or when the submersible body 1 moves to the right as a whole during a surge motion, as shown in Figure 5. Under the action of inertia, the water column in the liquid chamber 8 climbs into the first air chamber 3 on the left. The liquid level of the water column on the left increases, and correspondingly the liquid level of the water column on the right decreases. When the water column on the left rises, it will compress the gas in the first air chamber 3 and increase its pressure. At the same time, the liquid level of the water column on the right decreases, causing the gas in the second air chamber 4 to generate negative pressure. High-pressure gas can enter the third air chamber 5 through the first one-way valve 9. Since the second one-way valve 10 has an opposite passage direction to the first one-way valve 9, the high-pressure gas flow cannot flow out through the second one-way valve 10. . After the high-pressure airflow enters the third air chamber 5, since the paths of the first one-way valve 9 and the third one-way valve 11 are also opposite, the high-pressure airflow cannot flow out from the third one-way valve 11 and can only flow to the third one-way valve 11. Four air chambers6. After the high-pressure airflow enters the fourth air chamber 6, the airflow passes through the nozzle 14 and drives the one-way impulse air turbine 15 to rotate at high speed, converting the pressure energy of the high-pressure airflow into the rotational mechanical energy of the one-way impulse air turbine 15. The impulse air turbine 15 drives the permanent magnet generator 13 coaxially connected with it to rotate synchronously, converting the rotating mechanical energy into electrical energy. After the high-pressure air flow passes through the one-way impulse air turbine 15 to perform work, it turns into a low-pressure air flow and flows to the fifth Air chamber 7. Due to the pressure difference between the air pressure flow in the fifth air chamber 7 and the high pressure air flow in the first air chamber 3 (at this time, the pressure in the second air chamber is higher than that in the fifth air chamber), the pressure difference on both sides causes the second one-way valve 10 to If it cannot be opened normally, the low-pressure airflow in the fifth air chamber 7 can only enter the second air chamber 4 through the fourth one-way valve 12 to replenish the gas in the second air chamber 4 .

When the submersible body 1 performs a pitching motion under the action of waves, the bow moves upward, as shown in Figure 6, or when the submersible body 1 moves to the left as a whole during a surge motion, as shown in Figure 7. Under the action of inertia, the water column in the liquid chamber 8 climbs into the second air chamber 4 on the right. The liquid level of the water column on the right rises, and correspondingly the liquid level of the water column on the left decreases. When the water column on the left rises, it will compress the gas in the second air chamber 4, causing its pressure to increase. At the same time, the liquid level of the water column on the left decreases, causing the gas in the first air chamber 3 to generate negative pressure. High-pressure gas can enter the third air chamber 5 through the third one-way valve 11. Since the fourth one-way valve 12 has a passage direction opposite to that of the third one-way valve 11, the high-pressure gas flow cannot flow out through the fourth one-way valve 12. . After the high-pressure airflow enters the third air chamber 5, since the paths of the third one-way valve 11 and the first one-way valve 9 are also opposite, the high-pressure airflow cannot flow out from the first one-way valve 9 and can only flow to the third one-way valve 9. Four air chambers6. After the high-pressure airflow enters the fourth air chamber 6, the airflow passes through the nozzle 14 and drives the one-way impulse air turbine 15 to rotate at high speed, converting the pressure energy of the high-pressure airflow into the rotational mechanical energy of the one-way impulse air turbine 15. The impulse air turbine 15 drives the permanent magnet generator 13 coaxially connected with it to rotate synchronously, converting the rotating mechanical energy into electrical energy. After the high-pressure air flow passes through the one-way impulse air turbine 15 to perform work, it becomes a low-pressure air flow and flows to the fifth air chamber 7 . Due to the pressure difference between the pressure air flow in the fifth air chamber 7 and the high pressure air flow in the second air chamber 4 (at this time, the pressure of the second air chamber is higher than that of the fifth air chamber), the pressure difference on both sides causes the fourth one-way valve 12 to If it cannot be opened normally, the low-pressure airflow in the fifth air chamber 7 can only enter the first air chamber 3 through the second one-way valve 10 to replenish the first air chamber 3 with gas.

Specifically, the permanent magnet generator 13 is disposed inside the annular tube 2, and more specifically in the fifth air chamber 7, which can significantly reduce the volume of the latent object body 1, allowing the internal space of the latent object body 1 to be placed more efficiently. Many sensors.

In this embodiment, the Y-shaped armored photoelectric composite cable 16 and the vertical armored photoelectric composite cable 17 are mainly used as the mooring chain. To connect the submersible body 1 and the anchoring sinker 18 on the seabed, the Y-shaped armored photoelectric composite cable 16 and the vertical armored photoelectric composite cable 17 can withstand a large pulling force. Furthermore, the overall buoyancy of the submersible body 1 must be less than the net weight of the anchoring sinker 18 in the water, and the lengths of the Y-shaped armored photoelectric composite cable 16 and the vertical armored photoelectric composite cable 17 must be accurately calculated so that they are in tension. The tight state ensures that the latent specimen 1 can be suspended at the specified depth.

More preferably, detection equipment is installed on the cross section of the vertical armored photoelectric composite cable 17 .
