Detailed Description

The present invention will be described in detail with reference to fig. 1 to 3, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

The invention provides a composite glass fiber reinforced plastic catamaran type hydroelectric power station which realizes power generation by adopting the design of a hull, a permanent magnet generator, a composite glass fiber reinforced plastic turbine and a traction mechanism. As shown in fig. 1, the present invention includes a double hull 1, four permanent magnet generators 2 arranged side by side on the hull 1, a sound absorbing mechanism 6 arranged on the generators, multiple glass reinforced plastic turbines 5 arranged on both sides of the hull 1 and connected to the four permanent magnet generators 2 in one-to-one correspondence (specifically, a transmission 4 is connected to an output shaft of each multiple glass reinforced plastic turbine, and the transmission is connected to a rotor shaft of the generator on the same side through a coupling 3), and a traction mechanism 13 connected to the hull 1. The traction mechanism 13 is used for realizing the traction of the ship body so as to enable the ship body to stably float on the river, and gather and obtain the impact kinetic energy of the water flow. The traction mechanism can adopt the existing structural design, such as the design of a winch, a steel traction rope and a hook. And the hull of the hull 1 is made of composite glass fiber reinforced plastic materials, so that the weight is light, the floating is facilitated, the corrosion resistance is high, and the electric conduction is not realized.

The hydroelectric generation process of the invention is different from the working principle of the existing hydroelectric power station, and the hydraulic turbine is flushed by water, the kinetic energy of water flow is used for generating power (namely, the process of converting potential energy of water into mechanical energy and electric energy is realized), and finally, the power is modulated, regulated, stabilized and stabilized by the control room 14 and then is incorporated into a power grid, so the detailed description is omitted in the embodiment. The difference between the invention and the prior art is that the invention can be used in river canyons, deeper rivers, sea areas, islands and other water areas, thereby fully utilizing river water flow kinetic energy resources in China to realize hydroelectric power generation. Any river or sea current can be set with hull and installed capacity according to the implementation situation as long as the water flow speed meets certain requirements.

As another innovation of the present invention, the sound absorption mechanism 6 can effectively reduce the noise generated during the operation of the permanent magnet generator. As shown in fig. 2, in the present invention, the sound absorption mechanism includes a sound absorption layer 7 (which may be made of porous sound absorption material such as mineral wool, polyurethane foam, glass wool, etc.) disposed outside the permanent magnet generator (where noise is mainly generated), a housing 12 disposed outside the sound absorption layer 7, a plurality of through grooves 8 uniformly distributed on the sound absorption layer 7, wave-shaped reflection portions 9 disposed on both sides of the inner wall of the through grooves 8, and a first reflection block 10 and a second reflection block 11 disposed in the through grooves 8 and used for realizing multiple reflections of sound in cooperation with the wave-shaped reflection portions 9 (forming a curved flow path) and eliminating the sound after being absorbed by the sound absorption layer.

The silencing principle of the silencing mechanism of the invention is as follows:

as shown in fig. 3, with the design of the sound-absorbing mechanism of the present invention, when sound enters the through groove, most of the sound is absorbed by the through groove during the propagation process in the through groove through the repeated reflection of the curved flow channel of the through groove, and only the remaining small part of the sound is consumed up after multiple reflections, and finally, the sound is blocked by the outer cover, so that noise reduction can be well achieved.

In order to verify the effect of the sound-absorbing mechanism, the inventors of the present application have conducted relevant verification experiments exclusively. The sound absorption mechanisms are respectively arranged at a plurality of positions which are mainly used for generating noise outside the generator set, and experiments show that when the permanent magnet generator set runs at full load, the noise value measured at a position 1m away from the generator set is only about 45dB (lower than 60 dB). That is to say, adopt the sound mechanism of inhaling of this application, can guarantee staff's physical and mental health with permanent magnet generator set noise of operation to suitable decibel completely, also avoided all ring edge borders to be polluted.

In addition, the invention can also arrange a vibration damping and sound insulation plate (not shown in the attached drawing) at the bottom of the permanent magnet generator, so as to reduce the vibration generated when the permanent magnet generator works and further reduce the working noise of the permanent magnet generator. The vibration-damping sound-insulating board is a high-performance constraint damping structure board, is formed by compounding a high-performance viscoelastic damping sound-insulating coating and a constraint damping layer, and can effectively convert the vibration energy of sound waves into heat energy to be consumed, thereby playing a remarkable role in vibration damping and sound insulation.

Through reasonable structural design, the invention not only improves the use flexibility of hydroelectric power generation and the stability of the ship body, but also effectively solves the problem of the working noise of the generator set and reduces the vibration generated by the working of the generator set to a certain extent, therefore, compared with the prior art, the invention has substantial characteristics and progress.
