Fig. 3a is a schematic structural view of a magnetic screw composed of a magnetic screw stator rod and a magnetic screw rotor cylinder according to an embodiment of the present invention; fig. 3b is a schematic sectional structure view of a magnetic screw composed of a magnetic screw stator rod and a magnetic screw rotor cylinder according to an embodiment of the present invention. Referring to fig. 3a and 3b, the magnetic screw is formed by concentrically nesting a magnetic screw stator rod 130 and a magnetic screw rotor cylinder 240, and the spiral stator magnet 131 and the rotor magnet 241 with the same angle and different circle radiuses are respectively and tightly attached to the outer wall of the magnetic screw stator rod 130 and the inner wall of the magnetic screw rotor cylinder 240. When axial relative motion occurs between the magnetic screw stator rod 130 and the magnetic screw rotor barrel 240, the helical magnetic field of the helical magnet will guide the two back to the aligned position, thereby generating a torque that will guide the non-fixed one of the two to rotate. In the embodiment of the present invention, the magnetic screw stator rod 130 is in a fixed state, and the magnetic screw rotor cylinder 240 rotates.
Specifically, the surface of the magnetic screw stator rod 130 is spiral and is adhered with permanent magnets, and the permanent magnets are alternately arranged according to N, S rules. The magnetic screw driver cylinder 240 is formed by concentrically nesting an inner cylinder and an outer cylinder, wherein the inner surface of the inner cylinder is spiral, is adhered with permanent magnets, is alternately arranged according to N, S and is fixed in the outer cylinder.
When the wave power generation device provided by the embodiment of the invention is used for operation, firstly, the floater tilts under the thrust action of waves, the bracket 100 fixed in the cabin of the floater keeps still relative to the floater, and the motor platform 200 in the cabin slides in a fixed direction through the limiting optical axis 110 of the fixed bracket 100 and the linear bearing 211 under the influence of gravity or inertia force. When the motor platform 200 slides, the rotating structure 230 will drive the magnetic screw rotor tube 240 to move together with the motor platform 200, so that the magnetic screw stator rod 130 fixed on the bracket 100 and the magnetic screw rotor tube 240 move relatively, and since the position and the angle of the magnetic screw stator rod 130 are fixed, when the magnetic screw rotor tube 240 moves axially together with the motor platform 200, the magnetic screw rotor tube 240 also rotates with the help of the rotating structure 230, so as to drive the generator connected with the crawler belt to rotate, thereby completing power generation, and the generated electric energy is stored or directly used through the flexible wire connected to the generator. The generator is externally connected with a flexible power transmission conductor, and the input end of the conductor is connected with the output end of the generator. The output end of the lead can be connected to a storage battery or other electricity storage devices on the float equipment, and can also be connected to any electric equipment on the float equipment after adjustment.
In summary, the wave power generation device provided by the embodiment of the present invention generates power in two forms: the power generation is carried out by utilizing the gravity component and the power generation is carried out by utilizing the inertia. Wherein, the power generation process by utilizing the gravity component comprises the following steps: when the float cabin tilts due to the thrust of waves, the bracket and the cabin keep relatively static, the motor platform generates relative sliding between the linear bearing and the bracket due to the influence of gravity component after the motor platform tilts, and the magnetic screw stator rod on the bracket and the magnetic screw driver barrel on the motor platform also generate relative motion. Because the stator rod is fixed, the magnetic force of the spiral magnet pulls the stator rod to rotate on the motor platform, and the magnetic force lead screw rotor cylinder drives the generator rotor to rotate through the crawler belt to generate electricity.
The power generation process by using the inertia force comprises the following steps: when the thrust of the float cabin is greatly shaken due to the wave, the fixed support and the cabin keep relatively static, and the motor platform generates relative sliding through the linear bearing and the fixed support due to inertia, so that the magnetic lead screw drives the generator to generate electricity.
The wave power generation device provided by the embodiment of the invention can be independently taken out from the floater equipment, and different output ends can be subjected to power generation operation by using other modes or other carriers.
Because the axial and radial motions of the common magnetic lead screw are respectively completed by the rotor and the rotor, the wave power generation device provided by the embodiment of the invention integrates the two motions on the magnetic lead screw by fixing the lead screw and additionally installing a rotating part, a magnetic lead screw rotor cylinder 240 which is specially responsible for the motions is formed, the longest effective power generation stroke of the whole power generation device is increased, and the values are as follows: the length L of the magnetic lead screw stator rod is equal to the length L of the motor platform.
When the integral inclination angle of the floater is too large or the device is thrust by sea waves, the magnetic lead screw can automatically generate overshoot protection, the motor platform 200 can directly slide to the end point position without generating electricity and rotating, so that the transmission device cannot be damaged due to overload, and meanwhile, the magnetic lead screw does not physically contact and can also be prevented from being damaged in the protection generated by sliding.
The wave power generation device provided by the invention uses the magnetic lead screw as a transmission part for transmission, and generates power through transmission, however, the wave power generation device provided by the invention is not limited to the transmission form, and the transmission part can be completed by other forms of devices, for example, a ball type mechanical lead screw can also complete the same transmission function, at the moment, the ball lead screw needs to be subjected to anti-self-locking treatment so as to have the transmission function suitable for the embodiment of the invention, and at the moment, the transmission part loses the protection function when the axial force is too large.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
