Description

technical field [0001] The invention discloses a power generation device, in particular to a high-efficiency integrated double-rotor bidirectional generator device. Background technique [0002] Traditionally used generators are mainly composed of a stator and a rotor. The stator is fixed, and the rotor rotates to generate electricity. In recent years, some people have proposed a new type of generator structure, that is, the stator of the generator is removed, and instead it contains two rotors, and the two rotors can realize simultaneous reverse relative rotation by driving the conversion device. [0003] Although some people have designed generators that can meet these special requirements, and the general power generation principles of these generators are similar, but the key system for realizing the drive conversion device with dual rotors that can rotate in reverse at the same time is different. various.

Problems solved by technology

However, the device is more suitable for vertical arrangement, and the horizontal arrangement will have low structural strength, and it is difficult to meet the stable operation under a large force state.

[0005] In the patent No. ZL200910264407.4, it is disclosed that the drive conversion device is composed of a shunt transmission gear shaft, a reverse ring gear, a steering shaft, etc., and in the patent No. ZL201210334291.9, a planetary gearbox is used as a drive conversion device to realize double rotation. However, the starting torque of the generator is relatively large, and it is not easy to start

[0006] In the patent No. ZL02235745.9, it is disclosed that the inner shaft is fixedly connected with the inner rotor, and a set of impellers that rotate clockwise after being stressed by the torsion angle are installed; The rotors are fixedly connected, and at the same time, a set of impellers that rotate counterclockwise after being stressed by the torsion angle is installed, so as to realize the double rotor reversal. resistance, so the efficiency of the device will be lower

[0007] Combining the dual-rotor generators that have been developed so far, although they are different in terms of drive conversion devices, they have a common feature, that is, the fundamental principle is to use two shafts, and the two ends of each shaft are respectively connected to a The rotor is fixedly connected to an impeller, so the rotation of the dual rotors will change with the rotation of the impeller. This will not only affect the quality of power generation, but also cause the generator to start with high resistance and difficult to start, and its life is low. Therefore, the existing dual-rotor generators are only suitable for some specific occasions, such as in one-way fluid with stable flow velocity, but not for two-way power generation with unstable flow direction.
