Canal formula stream generating device

Technical field

The utility model relates to a kind of stream generating device, especially a kind of canal formula stream generating device.

Background technique

China is the abundant country of a water resources, is containing the huge energy.At present, the generator of the existing hydroelectric power plant of China all need be built the dam and make high water-head.But investment is big, it is slow to take effect, and influence or destroy environment is difficult to utilize to not building condition section, dam especially especially, only seeing huge hydraulic power potentials flows through but quietly to feel simply helpless.

Summary of the invention

The utility model is for overcoming above-mentioned deficiency, and a kind of dam of need not building is provided, invest little, use simple and do not destroy the canal formula stream generating device of ecotope.

The utility model is to realize like this, the main body of canal formula stream generating device is a rotating shaft, in rotating shaft two correspondence several flabellum framves is set, and is provided with flabellum between the corresponding flabellum frame, establish driving gear in flabellum frame outer end, this driving gear links to each other with generator by the speed change gear group.

As a kind of improvement of the present utility model: described flabellum is connected with flabellum frame outer end by connecting rod.

The utility model electricity generating device must be installed on the rectangle channel, and this channel water stream need have certain flow rate.During use, with the rotating shaft frame of electricity generating device on water channel two dikes, the water impact flabellum, the flabellum rotation drives the driving wheel rotation, driving wheel generates electricity transmission of power by the speed change gear group to generator.The utility model electricity generating device need not built the dam, has safeguarded the ecosystem environment, invest little, instant effect.Flow rate of water flow is the key that influences the utility model electricity generating device generating capacity, and flow velocity is bigger, and generating capacity is just bigger.Improving the flow rate of water flow scheme has two, and one is made compressional wave steep, and in certain section, the straightening of canal line is not walked curve with the natural torsion in river course, walks broken line in the time of need turning round, and the canal line is the shortest like this.The second, at the bottom of the canal and the roughness of canal bank little, with at the bottom of the canal and the canal bank all make concrete surface, reach smooth, the purpose that roughness is little.

The utility model electricity generating device has an outstanding characteristic, exactly electricity generating device of the present invention is placed under the specified conditions that turn round in the rectangle gool, and electricity generating device can be forced to increase the gratifying phenomenon of own energy.When electricity generating device turns round in the rectangle gool, the flabellum frame is near bank slope, the covering of the fan outer is tightly wiped at the bottom of the canal again, not before the generating, energy machine rotates naturally with current, and after beginning to generate electricity, energy machine rotating speed is inevitable slack-off, having partial discharge can not pass through, and the both sides of electricity generating device energy machine and bottom are keeping off at the bottom of Qu Qiang and canal are arranged, and the remainder current are at the end of one's rope, can only live in to gather around height, raising of water level, strengthened the water-head of upstream and downstream, electricity generating device has just increased water pressure like this, and the flabellum rotating speed is forced to accelerate, the current increasing of dropping, the generating capacity of electricity generating device also strengthen (can strengthen twice) thereupon.When on broad, big river, using, just repair an open channel (rectangle groove), and on the river course of head works, build the dam that blocks water, and on the dam, repair a sediment outflow lock in a side in river, this lock can also be in order to regulate water level, the water level in river course is transferred to the channel designing water level, and the depth of water that satisfies channel requires to get final product, like this can be with people's wish, how long how long just channel is wanted to repair is repaiied, just can build a water power plant about 100 meters, along with the prolongation of channel, also just increase accordingly in the power station.The power station of using the utility model electricity generating device to be built, the channel depth of water at place are bigger, and its generating capacity is just bigger, and the channel longitudinal gradient is bigger, and its generating capacity is also bigger.The utility model electricity generating device can not only also be applicable to the river generating in the generating of big korneforos, and just generated energy is littler.The water of abandoning of reservoir also can be used to generating.When on the river, the utility model being installed, after a flabellum is installed, impulsive force is very big, be not easy to control the rotation of flabellum, other flabellum can't be installed, so that the utility model is made flabellum is movable, promptly the flabellum upper end is installed on the flabellum frame by connecting rod, after the utility model is put into the river, the rotation of current impulsion flabellum.During installation, at first all flabellums like the rolling of curtain-type, the flabellum upper end is fixed on the flabellum frame, and then all flabellums is put down, install very convenient like this.
