Description

Wind power generation device and system
Technical Field
The invention relates to the wind power generation technology, in particular to a liquid transmission type wind power generation device and system.
Background
In the present day that petrochemical and coal-fired energy sources are gradually withered, wind power generation has become one of the key directions of human energy development. The data show that the total amount of globally exploitable wind energy resources is about 2 times the total amount of human energy demand. The richness and natural reproducibility of wind energy is the most attractive reason.
Wind power technology has originated in europe, where the development and initiatives for wind power in countries such as denmark, the netherlands, germany have been in history for over 20 years. Since the birth of the wind power generation technology, the wind power generation technology is continuously improved, and further developed into the structural forms of a horizontal shaft, three blades, a conical tubular tower and the like which are mature at present. The existing large-scale wind driven generator usually adopts a horizontal shaft type and consists of a tower, a wind wheel, a gearbox (an accelerating gearbox), a generator, a deviation device, a control system and other components. The wind wheel is used for converting wind energy into mechanical energy, and is formed by mounting blades with good air flow performance on a wheel shaft, and the low-speed rotating wind wheel is accelerated by an accelerating gearbox through a transmission mechanism so as to transmit power to a generator. The wind wheel is supported by a tall tower, and because the wind direction can be changed frequently, in order to effectively utilize the wind energy, an automatic windward deviation device is needed, and the wind wheel is pushed to be directly opposite to the windward side according to the wind direction signal measured by the wind direction sensor. It can be seen that, the wind wheels, the transmission mechanism and the generator in the traditional wind power generation device are in one-to-one mechanical connection relationship, and the characteristics cause the following problems in the existing wind power generation technology.
1. To meet the power scale and intensity of the disaster wind, the manufacturing cost is greatly increased
In the existing wind power generation technology, the single machine power generation is generally required to be as large as possible. At present, it is a established trend to develop wind power generation devices with a size of more than 1500kw, and the wind wheels of such units are large, with a diameter of more than 60 meters, and are mounted on towers with a height of tens of stories. It has been reported that huge wind turbine units with power of 3000kw, up to 300 feet in diameter, have been installed in california, usa. For such huge wind wheel and tower, it is required to bear the disastrous wind power in the area, so the strength requirement is very high, and it must be made of carbon fiber, glass fiber reinforced plastic and other high-strength materials, thereby the manufacturing cost is greatly increased.
2. To meet the power scale, the environment is negatively affected
On the one hand, the large wind wheels and the tall towers cause damage to the natural landscape in the local area, especially in urban and tourist areas, which is intolerable. In addition, when the propeller type wind wheel works, strong noise can be generated, the propeller type wind wheel becomes a noise source which is peaceful day and night, and the event of citizens visiting the wind power generation construction project in Netherlands and Germany occurs. At present, the minimum distance between the wind generating set and the residential house is usually required to be 500 meters, which greatly reduces the selection range of the region suitable for the installation of the wind generating set
3. The contradiction between the ultra-low rotating speed of the wind wheel and the economic rotating speed of the generator leads to the cost increase
For the large size wind turbine, the rotation speed is usually low, about 30 rpm. This extremely low rotational speed is far from the economic rotational speed of the generator, which, when coupled directly, results in a significant increase in the size, weight and cost of the generator. In order to achieve reasonable matching of rotating speeds, a proper mechanical speed change device is needed, a multi-stage planetary gear box is usually arranged on a tower frame of the existing product, the speed increase ratio of the multi-stage planetary gear box reaches 50-70, even more than 80, the used gear box is very heavy and weighs 50-100 tons, and the transportation and installation of the gear box are very difficult. In addition, the insertion loss of the multi-stage speed increasing mechanism can also reduce the efficiency of the whole generator set, so that the efficiency of the whole generator set is reduced by about 26%, and the serious waste of matched resources is caused.
4. The independently operated unit structure increases the construction cost
It can be known from the foregoing description that, in the prior art, the wind wheels, the transmission mechanism, and the generator are in a one-to-one mechanical connection relationship, and two or more wind wheels cannot be used to drive the same generator, which keeps the construction cost of the wind generating set high all the time, the construction cost of the current large wind generating set still remains at about 8000 yuan/kw, and the cost of the small wind generating set is higher.
Disclosure of Invention

According to the scheme, the power is transmitted by matching the liquid and the corresponding device instead of the traditional gear transmission mechanism, the energy loss of the liquid transmission mode is small, and the constant-speed driving of the generator is easy to realize. More importantly, the power of a plurality of wind wheels can be concentrated to the same generator through the collection of the liquid pipelines, so that the construction cost can be saved, and the power generation efficiency can be improved.

Detailed Description

In the specific implementation, the tower, the offset device, the control circuit and the like are included, but only the parts related to the operating principle of the wind power generation device are described here.
The wind wheel 101 is used for converting wind energy into rotational mechanical energy. The working principle, structure and the like of the wind wheel are mature prior art, when wind blows, the wind wheel can be driven to rotate by wind power, and the rotation of the wind wheel is output to the hydraulic pump 102 connected with the wind wheel through the rotating shaft. In order to further improve the efficacy of the whole wind power generation device, the inventor of the patent also improves the structure of the wind wheel in subsequent patents so as to enhance the function of automatically shifting the wind wheel in real time to adapt to the current wind direction.
The hydraulic pump 102 is used for increasing the input liquid (by being hydraulic oil) to high pressure and outputting the high pressure. In this embodiment, the rotating shaft of the hydraulic pump is fixedly connected with the rotating shaft of the wind wheel, so that the hydraulic pump and the wind wheel can rotate synchronously. When the hydraulic pump is rotated, the hydraulic fluid is sucked from the tank 106 through the second fluid line 110, pressurized and then delivered through the first fluid line 107. Regarding the structure and the theory of operation of the hydraulic pump, also mature prior art, the rotation type hydraulic pump that uses in this embodiment, rotatory in-process, the oil absorption chamber volume produces the vacuum and absorbs oil from little to big, and the oil extraction chamber volume extrudes fluid and discharges oil from big to little. If a multi-stage hydraulic pump is adopted, the transmission fluid can be pressurized to 10-25MPa and discharged. The inventor of the present invention will also improve the structure of the hydraulic pump in the following patent to enhance the pressurizing effect.
The hydraulic motor 104, which acts in opposition to the hydraulic pump, receives high pressure fluid from the hydraulic pump through the first fluid line 107 and rotates in response to the high pressure fluid. The rotating shaft of the hydraulic motor 104 is fixedly connected with the rotating shaft of the generator 105, so that the generator can be driven to synchronously rotate. After the high-pressure fluid passes through the hydraulic motor and drives it to rotate, the pressure is released and flows into the tank 106 through the third liquid transport tube 109. Regarding the structure and operation principle of the hydraulic motor, which is also mature prior art, the present embodiment uses a rotary hydraulic motor. The inventor of the present invention will also improve the structure of the hydraulic pump in the following patent to enhance the pressurizing effect.
The generator 105 in this embodiment may be a dc generator or an ac generator, which rotates synchronously with the hydraulic motor, so that mechanical energy can be converted into electric energy and output to a corresponding load. The tank 106 in this embodiment is used to store an appropriate amount of the driving fluid to ensure a normal flow of the driving fluid between the respective components.
In particular, in practice, it is preferable to adopt various means in the prior art, for example, by means of a pressure regulating valve, etc., to keep the pressure of the high-pressure liquid output by the hydraulic pump at a constant level as much as possible and keep the rotation speed of the hydraulic motor as constant as possible, and a speed-regulating transmission mechanism can be added between the hydraulic motor and the generator, so as to finally achieve the purpose of ensuring the generator to rotate at a constant speed.
The components in the embodiment are not purely mechanically connected, but hydraulic transmission effect is introduced, so that the power of the wind wheel can be transmitted to the generator at a far position through a liquid conveying pipe. On the basis, the wind power generation system shown in fig. 2 can be further manufactured.
Compared with the fig. 1, the liquid collecting tank 103 and the fourth liquid conveying pipe 108 are added in the embodiment shown in fig. 2, and two sets of wind wheels and hydraulic pump sets are arranged. In specific implementation, more sets of wind wheels and hydraulic pump sets can be arranged, namely, the number of the tower, the wind wheels and the hydraulic pumps in the wind power generation system can be N, and the tower, the wind wheels and the hydraulic pumps share the same set of hydraulic motor, the liquid collecting tank, the liquid storage tank and the generator, wherein N is an integer larger than 1.
The liquid collecting tank 103 is used for receiving the high-pressure liquid output by each hydraulic pump 102 and collectively outputting the high-pressure liquid to the same hydraulic motor 104 through a fourth liquid conveying pipe 108.
The rotating shaft of each wind wheel is directly or indirectly connected with the rotating shaft of one hydraulic pump, so that the hydraulic pumps can be driven to rotate together; the output port of each hydraulic pump is connected to the input port of the liquid collecting tank via a first liquid transport tube, and the input port of each hydraulic pump is connected to the output port of the liquid storage tank via a second liquid transport tube, so that there are two first liquid transport tubes 107 and two second liquid transport tubes 110 in this embodiment. The output of the hydraulic motor is still connected to the input of the tank via a third infusion line 109.
According to the scheme, the power is transmitted by matching the liquid and the corresponding device instead of the traditional gear transmission mechanism, the energy loss of the liquid transmission mode is small, and the constant-speed driving of the generator is easy to realize. More importantly, the power of a plurality of wind wheels can be concentrated to the same generator through the collection of the liquid pipelines, so that the construction cost can be saved, and the power generation efficiency can be improved. Since the same generator can be driven by a plurality of wind wheels, the volume of the wind wheels can be correspondingly reduced, and further the additional manufacturing cost can be reduced.
