Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings in order to better understand the present invention.
As shown in figure 1, the merchant ship bow floating body wave energy power generation device comprises a floating body (1), a floating body track (2), a ship body track (3), a rack (4), a gear (5), a transmission mechanism (6), a generator (7), a swing stopping spring (8) and a swing stopping base (9).
The floating body (1) is positioned at the bow part and above the waterline and is rigidly fixed with the floating body track (2), and the rack (4) is rigidly fixed on the central axis of the floating body track to promote the rack (4) to reciprocate up and down along with the floating body (1). In addition, as shown in fig. 6, the floating body (1) is a curved solid, only one side close to the ship body is a curved surface, the rest are planes, the floating body is positioned above a waterline, and the part facing the waves is sharpened, but if the included angle theta of the upper plane of the floating body is too small, a vortex is formed at the bow, and the included angle theta is too large, so that the water facing surface is too large, and the effect of reducing the resistance is not obvious. In consideration of the influence, the included angle theta of the upper plane of the floating body is set to be 30-60 degrees, the wave splitting effect of the device is obvious, and the reduction range of the resistance of the ship body is large.
The ship body track (3) is rigidly fixed with the ship body, and the ship body track (3) is matched with the floating body track (2) so that the floating body (1) reciprocates along the route.
The gear (5) is connected with the transmission mechanism (6), and the transmission mechanism (6) is connected with the generator (7) at the same time.
When the ship sails in heavy wind waves, the impact of the waves and the vertical oscillation of the bow can cause the floating body (1) to enter the water occasionally and to go out of the water occasionally, thus causing the change of the borne buoyancy.
When the floating body (1) enters water and the buoyancy borne by the floating body (1) is larger than the gravity of the floating body, the floating body (1) is rigidly connected with the floating body track (2), the ship track (3) is rigidly connected with the ship body, in addition, the floating body track (2) is matched with the ship track (3), the floating body (1) moves obliquely upwards along the track to drive the rack (4) which is rigidly connected with the floating body to move upwards along the extension line of the track, so that the rotation of the gear (5) which is meshed with the floating body is driven. The rotation of the gear (5) drives the transmission device (6) to work, and the transmission device (6) drives the generator (7) to generate electricity.
In a similar way, when the part of the floating body (1) immersed in water is less, the buoyancy force is smaller than the gravity of the floating body, the floating body (1) can move downwards along the track in an inclined mode to drive the rack (5) to move, and therefore the transmission device (6) drives the generator (7) to generate electricity. When the buoyancy borne by the floating body (1) is too small or not, the downward movement of the floating body (1) is too fast, and the oscillation stopping spring (8) has a buffering effect on the floating body, so that the floating body (1) is prevented from impacting the oscillation stopping base (9) too much and being damaged.
When boats and ships navigate in no stormy waves, the utility model provides a body (1) are located on the waterline, can not contact water, and the weight of body (1) relies on to stop swinging base (9) and supports, and this power generation facility body (1) can not reciprocating motion, so can not generate electricity.
The foregoing is only a preferred embodiment of the present invention, but is not limited to the above embodiments, and it should be noted that, for those skilled in the art, many modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should be regarded as the protection scope of the present invention.
