Detailed Description
The sea wave power generation device comprises an offshore power generation platform and is formed by combining a plurality of stages of 'sea wave power generation differential assembly shafts', and the sea wave power generation differential assembly shafts comprise differential assembly shafts of the last stage where each floating body is located and a plurality of stages of differential assembly shafts in the middle between the differential assembly shafts and a generator shaft. One differential is provided for each differential assembly shaft. The differential assembly shafts of the plurality of stages are called as differential assembly shafts of the middle stage in the specification, the differential assembly shafts of each final stage are correspondingly connected with a floating body on the left, the right and the left respectively, the floating bodies are installed on an offshore power generation platform, and the movable positions of the floating bodies are limited by bearing seats, pulleys and the like to form a fixed offshore generator set whole.
The receiving belt pulleys on both sides of each intermediate differential assembly shaft are connected with the output belt pulleys mounted on the differential shells of the two differential assembly shafts of the next stage. The two groups of differentials at the lower stage drive a receiving belt pulley at the upper stage through a driving belt, and energy is transmitted to a wave power generation differential assembly shaft at the upper stage until the wave power generation differential assembly shaft at the stage is directly connected with a wave power generator for transmission. In this way, the kinetic energy of the individual floats can be effectively utilized.
In the arrangement of the differential assembly shaft stages of the sea wave power generation device, when the differential assembly shafts of the final stage are increased by one stage, the number of the differential assembly shafts of the previous stage is twice that of the differential assembly shafts of the final stage, and the size of the floating body is twice that of the floating body. The number of the floating bodies can be increased in countless stages according to the power requirement, so that an effective sea wave power generation device capable of generating enough output power is formed.
The design key point of the invention is a differential assembly shaft. Two receiving belt pulleys are arranged on two sides of each differential assembly shaft of the middle stage and used for receiving the work done by the floating body, and overrunning clutches are arranged on two sides of the differential assembly shaft of the final stage and used for receiving the work done by the floating body.
The differential mechanism adopted in the invention can adopt a simpler common differential mechanism structure, and the common differential mechanism has the following composition structure: planetary gear, side gear, planet gear axle, differential case. The differential mechanism of the invention is composed of the following components corresponding to the common differential mechanism: coaxial bevel gear, side bevel gear, differential half axle, differential case. The differential case is a commonly-known planetary gear carrier, and the attached drawings and the specification of the invention are not marked with numbers because the concept of the differential case is visual.
In a common differential, power of an engine enters the differential through a transmission shaft to directly drive a differential shell, and then a left half shaft and a right half shaft are driven by a planetary gear, so that the differential is used for driving a left wheel and a right wheel of an automobile respectively. In the differential assembly shaft, two differential half shafts correspond to the left half shaft and the right half shaft, and the two half shafts are identical in position.
Some floating bodies in the sea wave power generation have higher ascending amplitude, and some floating bodies have lower ascending amplitude, so that the left wheel and the right wheel roll at different rotating speeds when the automobile turns or runs on an uneven road surface, and the advancing of the automobile can be effectively pushed. The differential of the present invention is related to the reverse application of the automobile differential, and functions to transmit the kinetic energy obtained by the floating bodies 18 at both sides to the generator shaft layer by layer with great efficiency. The floating body splicing method is different from the method that a plurality of floating bodies are directly spliced on a long main shaft in a line, and the lifting amplitude of some floating bodies is small, so that the work can not be effectively done on the main shaft.
When the overrunning clutch shaft connected with the floating body drives the two coaxial bevel gears to rotate, the driving side bevel gear rotates to further drive the differential case to rotate, the output belt pulley arranged on the differential case drives the main shaft mechanism of the generator to rotate, at the moment, the two floating bodies with different rising amplitudes can apply work to the output belt pulley, the floating body in the whole sea wave power generation device can apply work to the generator shaft, and the generator effectively utilizes the energy of each floating body.
