Detailed Description
The technical scheme of the invention is further described below with reference to the accompanying drawings.
Fig. 1 shows a schematic structural diagram of a lightweight mechanical wave power mechanism based on a swinging device. In the figure, the lightweight mechanical wave power generation mechanism based on swinging equipment comprises swinging equipment 6, a generator, a speed increaser 3a, a weight 8, a commutator 11 and an inertia wheel 21. The swinging device 6 is fixedly connected with the right rotating shaft 4 and the left bearing 15 which are positioned on the same axis. The weight 8 is fixedly connected with the speed increaser housing 3 through the right connecting rod 7 and is fixedly connected with the generator housing 23 through the left connecting rod 9. The input end of a speed increaser 3a in the speed increaser shell 3 is connected with a right rotating shaft 4, and the output end of the speed increaser 3a is connected with a middle rotating shaft 2. The commutator 11 is provided with a right bevel gear 1, an upper bevel gear 13, a left bevel gear 14 and a lower bevel gear 18 which are meshed with each other, the right bevel gear 1 is fixedly connected with a middle rotating shaft 2 supported by a right bearing 5, the left bevel gear 14 is fixedly connected with a left rotating shaft 16 supported by a left bearing 15 and a middle bearing 17, the upper bevel gear 13 is arranged at one end of a long rotating shaft 22 through an upper one-way bearing 12 and the lower bevel gear 18 through a lower one-way bearing 19, the long rotating shaft 22 is supported by an upper bearing 10 and a lower bearing 20, and the other end of the long rotating shaft 22 is fixedly connected with a generator rotor 23a in a generator shell 23 through an inertia wheel 21. When the wave power generation mechanism works, the weight 8, the right connecting rod 7, the left connecting rod 9, the speed increaser shell, the reverser shell, the flywheel 21, the long rotating shaft 22 and the generator shell can do low-speed reciprocating swing by taking the right rotating shaft 4 as a center as a whole, the swinging equipment 6 and the right rotating shaft 4 do medium-speed reciprocating swing, the middle rotating shaft 2, the right conical gear 1, the upper conical gear 13, the lower conical gear 18, the left conical gear 14 and the left rotating shaft 16 do high-speed reciprocating rotation, and the long rotating shaft 22 and the flywheel 21 do continuous high-speed unidirectional rotation to drive the generator to generate power.
By adopting the technical scheme, when the swinging equipment swings, the weight, the right connecting rod, the left connecting rod, the speed increaser shell, the reverser shell, the inertia wheel, the long rotating shaft and the generator shell are relatively low in swinging speed under the action of inertia force, gravity and friction force, and the swinging speed of the right rotating shaft fixedly connected with the swinging equipment is relatively high. The speed increaser increases the relative swinging speed by a plurality of times and transmits the relative swinging speed to the middle rotating shaft, and drives the right bevel gear to reciprocate at a high speed. The right bevel gear drives the upper bevel gear and the lower bevel gear which are meshed with each other to reciprocally rotate at a high speed at a speed opposite to the direction. When the rotation direction of the right conical gear points to the left (right) side (right hand rule, lower same), the rotation direction of the upper conical gear points to the upper (lower) side, the rotation direction of the lower one-way bearing points to the lower (upper) side, the upper one-way bearing is in a release state and freely rotates in the rotation direction pointing to the upper side, the lower one-way bearing is in a locking state and drives the long rotating shaft to continuously rotate in a one-way mode, and the rotation direction points to the lower side. On the contrary, when the rotation direction of the right conical gear is directed to the right, the lower one-way bearing is in a release state to be directed to the upper side to rotate freely, the upper one-way bearing is in a locking state to drive the long rotating shaft to rotate continuously and unidirectionally, and the rotation direction is directed to the lower side, so that the long rotating shaft always rotates unidirectionally. The left conical gear and the left rotating shaft can rotate freely in the middle bearing and the left bearing under the driving of the upper conical gear and the lower conical gear. The inertia wheel enables the long rotating shaft to rotate unidirectionally and stably at high speed under the inertia action, and then the generator rotor is driven to rotate to generate electricity.
When the power generation equipment is in a normal working state, the weight, the right connecting rod, the left connecting rod, the speed increaser shell, the reverser shell, the inertia wheel, the long rotating shaft and the generator shell can do low-speed reciprocating swing by taking the right rotating shaft as a center as a whole. The swinging equipment and the right rotating shaft do medium-speed reciprocating swinging, the middle rotating shaft, the right conical gear, the upper conical gear, the lower conical gear, the left conical gear and the left rotating shaft do high-speed reciprocating rotation, and the long rotating shaft 22 and the inertia wheel 21 do continuous high-speed unidirectional rotation. The generator may be an ac or dc generator.
