Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a wind heating device that generates heat using a wind turbine and uses the thermal energy for heating.

2. Description of the Related Art A conventional wind heating system has a configuration as shown in FIG. That is, a power transmission device 2 that transmits the rotational power of the wind turbine 1 via a gear device 3 drives an oil pump 6 that produces high-pressure, high-temperature oil. A heat generating device 4 is constituted by this oil pump 5 and a heat exchanger 6 that converts the thermal energy of this high temperature oil into thermal energy of water. After the water is converted into thermal energy by the heat exchanger 6, it is stored in a heating chamber 8 and sent to a radiator 7 which radiates the thermal energy of the water. According to this configuration, the rotational energy of the windmill 1 drives the oil pump 6 to compress the oil, and this compression increases the temperature of the oil, so this thermal energy is transferred to the heating chamber via the heat exchanger 6 and the radiator A. The plan is to use it for heating.

Problems to be Solved by the Invention In such a conventional configuration, since the heat generating device 4 and the heating chamber 8 are arranged separately, it is necessary to completely insulate the heat generating device 4, and There is a problem in that a thermal energy conversion loss due to the exchanger 6 and a thermal energy transport loss to the heating room occur, resulting in a lower overall wind energy thermal energy conversion efficiency.

The present invention solves these problems by using an air compressor as a heat generating device and storing the air compressor in a heating chamber, thereby eliminating the need for heat insulation treatment and eliminating the need for a heat exchanger. The purpose of this is to improve the total energy conversion efficiency by eliminating the energy conversion loss caused by heat transfer and the thermal energy transport loss to the heating room.

Means for Solving the Problem In order to solve this problem, the present invention provides a power transmission device comprising a windmill, an oil pump driven by the windmill, a hydraulic motor, and an oil cooling device, It is equipped with an air compression type heat generation device driven by the device, and the oil cooling device of the power transmission device and the heat generation device are housed in a heating chamber.

Operation With the above configuration, the oil pump is first rotated by the rotational force of the windmill, and the hydraulic motor is rotated by the energy of the pressure oil generated thereby. When the hydraulic motor rotates, it drives the air compressor, so that the rotational energy of the windmill is transmitted as the rotational energy of the air compressor. When the air compressor is operated, the pressure of the air on the discharge side is increased, and the discharged air gains high temperature heat. In this way, the air compressor will function as a heat generating device.

Furthermore, the oil flowing through the oil pump and hydraulic motor is
As the temperature rises, effective use of thermal energy can be achieved by simultaneously performing cooling and heat recovery using an oil cooling device.

Example An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, an oil pump 1° is installed which is directly connected to the wind turbine shaft 11 and generates pressure oil using the rotational energy of the wind turbine 9. Pressure oil produced by this oil pump 1o is sent to the hydraulic motor 13 via a hydraulic hose 1211. The high-temperature oil that has passed through the hydraulic motor 5 is cooled by an oil cooling device 14 via a hydraulic hose 12b, and is returned to the oil pump 1o via a hydraulic hose 12c. An air compressor 16 connected to a hydraulic motor 5 by a shaft 8 is connected to an air suction pipe 17 that sucks air from outside, and an air discharge pipe 18 that discharges air discharged from the air compressor 15 to the outside. A radiator 19a and a valve 2o are provided.

The air compressor 15 includes a cooler 2 that cools the cylinder 22.
1 is provided. 16 is an oil cooling device 14 and a cooler 2
A circulation pump 23 that circulates water between the radiator 19b and the radiator 19b is provided, and these pumps are connected to pipes 24a, 24b, and 19b, respectively.
They are connected by 24c, 24d, and 24e. Also,

19b, the circulation pump 23, and the like are housed in the heating chamber 25. In addition, oil pump 10. Hydraulic hose 12a.

12b, 12c, hydraulic motor 13. Since the oil cooling device 14 has a function of transmitting the rotational power of the windmill 9 to the air compressor 16, it is collectively referred to as a power transmission device 26.

In the above configuration, when the windmill 9 rotates, the oil pump 1o is driven via the windmill shaft 11, and the high pressure oil produced thereby flows through the hydraulic hose 12 as shown by the arrow and is supplied to the hydraulic motor 3. When the hydraulic motor 13 is driven by this pressure oil, the air compressor 15 starts rotating via the shaft 16, and thus the rotational power of the windmill 9 is transmitted as the rotational power of the air compressor 15. . The oil discharged from the hydraulic motor 13 is sent to the oil cooling device 14 via the hydraulic hose 12b, where it is once cooled and then returned to the oil pump 2 via the hydraulic hose 2C.

Next, when the air compressor 15 rotates, the air sucked from outside through the air suction pipe 17 undergoes a compression stroke by the air compressor 15, and then is discharged from the air discharge pipe 18 to the outside. Here, a radiator 19a provided in the middle of the air discharge pipe 18
To explain the operation of the valve 2o, the temperature of the air compressed by the air compressor 15 rises somewhat due to the heat of compression of the air, and after radiating this heat through the radiator 19a, it is released outside. In this embodiment, the pressure of the air discharged from the air compressor 15 can be increased by restricting the flow rate of air with a valve 2Q provided in the middle of the air discharge pipe 18. Therefore, the heat of compression of the air is greater than in the normal case, and higher temperature air thermal energy can be obtained.

On the other hand, since the cylinder 22 of each air compressor is heated by the heat of compression of the air, it is necessary to cool it when operating continuously. Furthermore, since the temperature of the oil flowing through the power transmission device 26 also rises due to the heat of compression by the oil pump 10, it is necessary to cool it in the same manner as described above. In the present invention, at the same time as performing the above-mentioned cooling, the thermal energy obtained at that time is also effectively used, and the circulation pump 23 is used to flow cooling water into the cooler 19 and the oil cooling device 14 as shown by the arrows. 22 and cooling the oil. Furthermore, the heat energy of the water obtained at this time is radiated by the radiator 19b and used for heating the heating chamber 26.

As described above, according to this embodiment, by adjusting the pressure of the air discharged from the air compressor, it is possible to obtain air thermal energy at a much higher temperature, and also to cool the cylinder of the air compressor and use the power transmission system. Thermal energy obtained during oil cooling can also be used effectively, making it possible to obtain thermal energy more efficiently.

Effect of the invention As described above, the present invention provides a wind turbine and an oil pump.
