Description

Technical Field

[0001] The utility model relates to a novel ocean energy diversion device. Background Art

[0002] With the development of clean energy, ocean energy power generation technology has gradually matured. A turbine is a power machine that converts the energy of water flow into rotational mechanical energy. Generally speaking, the higher the water head and the faster the flow rate, the greater the output power of the turbine. When the turbine obtains tidal energy, its external guide device can increase the flow rate of the internal seawater and increase the output power of the turbine. However, as the seawater flow rate gradually increases, the guide device still accelerates the flow of seawater, which reduces the working time of the turbine within the working flow rate range, resulting in the problem of low output power of the turbine. Utility Model Content

[0003] The utility model provides a novel ocean energy diversion device.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A novel ocean energy guide device comprises two fixed guide plates, wherein the upper and lower ends of one side of the two fixed guide plates are provided with stop blocks, and the upper and lower ends of the other side are provided with axial holes, wherein the setting position of the axial holes is closer to the horizontal symmetry axis of the fixed guide plates than the position of the stop blocks; the two fixed guide plates are arranged opposite to each other, and the stop blocks are located on the inner sides of the relatively arranged fixed guide plates, and two movable guide plates are connected to the axial holes on the upper and lower sides by rotating shafts respectively, and the movable guide plates are connected to the rotating shafts, and the movable guide plates are divided into long side guide plates and short side guide plates by the rotating shafts, and the top of the short side guide plates arranged at the upper ends of the fixed guide plates are provided with weight blocks; an expansion angle is formed between the two long side guide plates, and the outer ends of the long side guide plates are in contact with the stop blocks on both sides.

[0006] Preferably, the stop blocks of the two fixed guide plates are arranged relative to each other.

[0007] Compared with the prior art, the utility model discloses a novel ocean energy guide device, in which two movable guide plates are connected to the upper and lower axial holes of the fixed guide plate by a rotating shaft, and the movable guide plate is divided into a short side guide plate and a long side guide plate, and a weight block is arranged on the top of the short side guide plate at the upper end. Due to the gravity of the weight block on the upper movable guide plate and the gravity of the long side guide plate on the lower movable guide plate, the upper and lower long side guide plates form a certain expansion angle. Due to the existence of the expansion angle, the guide device has a large improvement in the flow rate of seawater, and the movable guide plate can move around the rotating shaft. When the flow rate of seawater gradually increases, the movable guide plate starts to rotate around the rotating shaft, and the expansion angle between the two long side guide plates gradually decreases, and the performance of the guide device in improving the flow rate of seawater is reduced, thereby ensuring that the turbine has a relatively high flow rate working range.

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] like Figures 1 to 3 As shown, a novel ocean energy guide device includes two fixed guide plates 1, wherein stop blocks 11 are provided at both upper and lower ends of one side of the two fixed guide plates 1, and shaft holes 12 are provided at both upper and lower ends of the other side, wherein the shaft holes 12 are provided at positions closer to the horizontal symmetry axis of the fixed guide plates 1 than the stop blocks 11; the two fixed guide plates 1 are relatively arranged, the stop blocks 11 are located on the inner sides of the relatively arranged fixed guide plates 1, and the positions of the stop blocks 11 of the two fixed guide plates 1 are relatively arranged.

[0013] Two movable guide plates 2 are connected to the axial holes 12 on the upper and lower sides by means of the rotating shaft 3, respectively. The movable guide plates 2 are connected to the rotating shaft 3, and are divided into a long side guide plate 21 and a short side guide plate 22 with the rotating shaft 3 as the boundary. A weight block 4 is provided at the top of the short side guide plate 22 arranged at the upper end of the fixed guide plate 1; the long side guide plate 21 arranged at the lower end of the fixed guide plate 1 sinks because its weight is greater than that of the short side guide plate 22, and the short side guide plate 22 arranged at the upper end sinks because its weight is greater than that of the long side guide plate 21 due to the weight of the weight block 4, so that an expansion angle is formed between the two long side guide plates 21, and the outer ends of the long side guide plates 21 are in contact with the stop blocks 11, which limit the expansion angle between the two long side guide plates 21.

[0014] Due to the existence of the expansion angle, the guide device has a greater increase in the flow rate of seawater; when the flow rate of seawater gradually increases, due to the large flow area of ​​the long side guide plate 21, it is subjected to a greater thrust from the seawater. When the torque of the thrust of the seawater is greater than the total torque caused by the guide plate and the load, the movable guide plate 2 begins to rotate around the rotation axis 3, and the expansion angle between the two long side guide plates 21 gradually decreases, and the performance of the guide device in increasing the flow rate of seawater is reduced, ensuring that the turbine has a relatively high flow rate working range. If the flow rate of seawater decreases, the gravity of the movable guide plate is used as a driving force to rotate, and the expansion angle between the two long side guide plates 21 becomes larger, which further improves the performance of increasing the flow rate of seawater, so that the power output of the turbine is always maintained at a large state.

[0015] The utility model discloses a novel ocean energy guide device, in which two movable guide plates 2 are connected by a rotating shaft 3 on the upper and lower shaft holes 12 of a fixed guide plate 1, and the movable guide plate 2 is divided into a short side guide plate 22 and a long side guide plate 21, and a load block 4 is arranged on the top of the short side guide plate 22 at the upper end. Due to the gravity of the load block 4 on the upper movable guide plate 2 and the gravity of the long side guide plate 21 on the lower movable guide plate 2, the upper and lower long side guide plates 21 form a certain expansion angle. Due to the existence of the expansion angle, the guide device has a large improvement in the flow velocity of seawater, and the movable guide plate 2 can move around the rotating shaft 3. When the flow velocity of seawater gradually increases, the movable guide plate 2 starts to rotate around the rotating shaft 3, and the expansion angle between the two long side guide plates 21 gradually decreases, and the performance of the guide device in improving the flow velocity of seawater is reduced, thereby ensuring that the turbine has a relatively high flow velocity working range.

[0016] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
