Description

Tidal current power generation device

technical field

The utility model relates to a tidal current power generation device; specifically, the utility model relates to a tidal current power generation device which can be used for underwater operations.

Background technique

At present, nuclear power generation and thermal power generation are still the main sources of domestic power generation. However, thermal power generation needs to rely on a large amount of imported fuel, which has high operating costs and has a greater impact on the environment. In terms of nuclear power generation, the cost of building power generation equipment is high, and the disposal of nuclear waste will also impose a burden on the environment. In addition, the urban area adjacent to the power plant is often narrow and densely populated, and the land suitable for development is limited. Projects that can reduce the occupied area and improve the mobility of power generation are currently a major demand for the development of new energy.

In addition, taking the power generation method using ocean currents and tides as an example, although it has the advantage of providing clean energy, the power generation efficiency varies greatly in different locations. In addition to relying on meteorological observation data, it still needs to cooperate with actual underwater operations to obtain More detailed ex-ante assessment. In addition, if only fixed locations are used to build power generation equipment in the sea environment, the risk of construction or maintenance for the staff is relatively high. Therefore, the use of fixed locations to build power generation equipment also has its limitations. In short, in addition to the current energy development projects, there is still a need to find other alternative energy sources. In order to meet the demand for power supply, it has become an important issue to find new energy while reducing the impact on the environment and reducing the burden on the land while maintaining the safety of personnel during construction or maintenance.

It should be noted that the shape of the power generating body 204 is not limited to the one shown in FIG. 1A , and its shape can also be in different forms such as cylindrical shape and tapered tube shape.

On the other hand, an air intake device 300 is also provided on the top surface 104 of the tidal current power generation device 100 . The air intake device 300 has an air intake main body 302 and a plurality of air intake branch pipes 304 , wherein the air intake main body 302 delivers external air and distributes the external air into the carrier 102 through the air intake branch pipes 304 .

Please refer to FIG. 1B , as shown in FIG. 1B , the interior of the carrier 102 is divided into six accommodating spaces 106 by walls 114 for storing water, and each accommodating space 106 is independent of each other. The aforementioned external air enters into each accommodation space 106 through the intake branch pipe 304 . In addition, the drainage device 400 is disposed on the bottom surface 108 of the carrier 102 and communicated with the accommodating space 106 . In this way, the water stored in the accommodating space 106 can be discharged through the drainage device 400 by the air poured into it. In other embodiments, a drainage motor may also be provided on the bottom surface of the carrier to accelerate the drainage of moisture stored in the accommodating space.

In the embodiment of FIG. 1B , the accommodating space 106 is divided into six, but not limited thereto. The accommodating space 106 can be divided into an appropriate number depending on the required size of the carrier 102 and the rate of water discharge and air intake.

For example, in this process, the way the floating ball 500 regulates the air intake rate of the tidal current power generation device 100 can use the displacement calculated from the pre-measured data such as ocean current velocity, water depth, and tidal changes to control the air intake rate. In addition, the tidal current power generation device can also cooperate with underwater monitoring devices, such as photographic lenses, and the water level sensor to confirm the actual situation of the internal water level of the tidal current power generation device, so as to determine the adjustment of the air intake rate. Furthermore, an induction meter can also be installed at the anchoring part to confirm whether the tidal current generating device is close to the seabed, and adjust the air intake rate accordingly. In other embodiments, the buoy 500 can also be equipped with a signal transceiver device, depending on the diving speed and depth of the tidal current power generation device 100, the remote operator can adjust the intake speed so that the tidal current power generation device 100 can maintain a stable dive. speed.

As shown in FIG. 5 , after the underwater power generation operation is completed, the tidal current power generation device 100 retracts the anchoring portion 110 , and fills in air from the floating ball 500 to empty the stored water. At this time, the tidal current power generation device 100 is pushed up by the buoyancy of the seawater and moves toward the sea level. As mentioned above, the anchoring portion 110 is connected to the bottom surface, but not limited thereto.
