Motor driven wind power generation system

Technical field

This invention is a hybrid generator of motor and wind power. In other words, while the motor is in the evening—while the bin speed sensor indicates that only wind that does not reach power generation is blowing, the motor instead connects the generator rotor directly with the motor pinion. When the wind blows and the number of revolutions of the wind turbine reaches the maximum level, the turbine pinion is connected to the other end of the rotor to generate electricity. Therefore, the characteristics of this generator are that it always generates and supplies electric power regardless of the wind condition, and that the power generation performance is better in each stage compared to conventional wind power generators, and compact and compact. Manufacturing costs are low. This is achieved by rotating the blades of the radial turbine, which is built into the belting turbine with a slit in the front, by applying a wind of about 100% to the blades of the radial turbine. This is because the wind speed in the inside is structurally accelerated by about 10 times or more, and the turbine is rotated by the wind power to generate electricity. Therefore, the power generation system can generate wind power even in light winds, and high-performance wind power can be generated throughout the year in town. In the meantime, it is a generator that generates power from a motor that can be continuously used instead of a battery when there is no wind or near it. Background art

A conventional wind power generator is a power generation system that uses natural wind power as it is as a turbine. Therefore, it is important to secure the natural wind, and the conditions for selecting the installation site for the equipment are strict. The result is a simple structure. Particularly in the case of large-scale power generation, three-bladed propeller-type turbines are used in many cases so as to prevent the generation of headwinds that become wind loads. The configuration for this is: wing, mouth-to-head, main shaft, nacelle, tower. The wind energy is converted into rotational energy by the wings and then transmitted to the gearbox via the wing interlocking shaft, rotor head, and main shaft. The nacelle has a built-in high-speed gear and a generator. In the gearbox, the speed of the blades is reduced up to the rated speed of the generator with one gear. The generator converts the transmitted rotational energy into electrical energy. In either case, induction or synchronous generators are used as generators. In either case, for the safety of the entire wind power generator, the power generation is stopped when the wind speed reaches a certain level or more in feathering operation. The result is lower. For this reason, the power generation efficiency throughout the year often falls below 20%. In addition, large-scale installation is required, and it is difficult to secure the installation site. Therefore, a large amount of cost is required including the offshore power generation that has been studied. is. Disclosure of the invention

The present invention is a hybrid motor and wind power generator that uses a rotating force that pushes and rotates a radial-type turbine blade at a wind speed that structurally accelerates the inflow of air from a casing slit by more than 10 times. This is a wind power generation system that can easily generate large power in the city due to natural winds because it can generate enough power at wind speeds of about lm / s or more because the generator's rotor rotates to generate power. For this purpose, a function to prevent noise is to rotate the turbine inside the casing, and to secure the power supply by driving the motor in a windless state, we have developed a secondary battery that can be used continuously. By using the power supply, power can be supplied, and at the same time, power is continuously supplied by generating electricity in order to maintain the drive of the motor which is connected in series and used as a power source as necessary. In this case, the generated power is connected to the ignition coil and boosted to a voltage suitable for the intended use. The principle of structurally accelerating the airflow entering from the slit by about 10 times or more is that the rear end of the roof of the casing is bent outward, and a screen is set up immediately after the upper half of the turbine. This is a phenomenon in which the airflow is pulled and accelerated by the eddy current generated by the differential pressure across the partition, and this wind power pushes and rotates the turbine blade to rotate the rotor of the generator to generate electricity. In this case, the vortex generated after the screen after the turbine draws the airflow in the casing. In addition to the action of stretching, the direction of the air flow is reversed, the rotation blade of the lower body of the turbine blade is pushed to accelerate the rotation, and the air flow rising along the partition plate on the bottom surface of the casing is used as the inlet of the slit. It is oriented to the end of the partition plate that is bent slightly inward and protrudes from the vicinity, merges with the new wind entering again from the slit, and pushes and rotates the blade. In addition, the battery that can be used continuously is a three-tiered container with a battery cell of lead-acid rechargeable batteries in the middle, connected with thin holes, and filled the upper container with dilute sulfuric acid of the electrolytic solution. Instill in one cell. As a result, the product of the chemical reaction accompanied by discharge is stored in the empty container in the third stage, so that the concentration of the electrolyte is not diluted, so that power is supplied to the motor without voltage drop until the active material on the electrodes is exhausted. The motor is driven continuously to generate electricity from the generator. On the other hand, in the containers after discharge, electrode plates to which no active material is attached are installed in containers other than the battery cell, and when the active material is filled with the solution generated by the molten chemical reaction, it is automatically turned off. Since the container moves around to the place where charging occurs due to the reverse current working, the other battery and one cell are discharged in order while one container is being charged, and the motor is driven. Here, the power to be charged can be the surplus power generated as a result of wind power generation, or the surplus transmitted power at night can be used. In addition, a weight that slides freely along the blade is fitted to the radial turbine blade of the wind power generator. In addition, the weight acts as a flywheel using centrifugal force to use the inertial force, and also serves as a governor for controlling the rotational force of the turbine. For example, in the case of a strong wind, the tip of the weight is covered with a coating such as rubber to contact the inner wall of the housing ceiling, and the frictional force acts to control the turbine rotation, eliminating the need for feathering operation and removing the ignition coil. In combination with the operation of the present invention, it is possible to constantly supply high-quality power. Up to now, in the case of a windmill with three propellers, assuming that the expected angle of one propeller is within about 10 degrees, the total angle of the three propellers is within 30 degrees, and out of 360 degrees around the circumference, The wind penetrated between the wings of the propeller on 30/360, and about 10 times the energy of the wind was discarded without being used for power generation. All of the wind entering the slit in front of the casing is converted into electrical energy from rotational energy by pressing against the turbine blade by converting the turbine into a radial turbine blade. Will contribute to power generation. On the other hand, the following relational expression holds for the wind speed when natural wind enters the casing through the slit. That is, pZ2U ² + P, = p / 2 v ~ X (1 + Σ Γ) + P2---(1) (P, -P¾) XA = p / 2 C dU ² A ― 1 1 1 ― (2 ) Each character is u: wind speed, V: wind speed through slit, ∑ Γ: Loss coefficient due to the contraction of the slit part and the rapid expansion of the casing. The contraction of the slit part is {(lZCe)-I} ² ": C _C = 1.0 ( Rounding), the loss of the rapid expansion is f {1— (a / A)} ξ = 1.0 a: slit cross section, A: casing cross section. P, — Pi: key Sing Pressure difference between front and inner surfaces, C d: resistance coefficient of casing, C d = 2.0 (2D rectangle, may be small)

Thus, from Eqs. (1) and (2), the rate of increase in wind speed is

v / J = F (C d + 1) / (1 + ∑ Γ) 1-(3) Assuming a / A = 0.1, a simple calculation gives / U = ”3Z1.81 = 1.3 ， The natural wind speed is increased by 30%. Therefore, when the natural wind passes through the slit, the wind speed of the airflow in the casing increases by 30% of that of the natural wind, and the vortex generated by the differential pressure generated after each wall. The radial wind turbine blade is rotated by the wind accelerated by pulling the airflow with a scroll under the action of tensile force to generate electricity. In this regard, in wind power generation, it has been proved that the electromotive force is proportional to the square of the length of the rotor blade and to the cube of the wind speed. The results show that the power generated is more than 10 times that of a propeller-type wind generator. BRIEF DESCRIPTION OF THE FIGURES

Fig. 1 is an example of a cross-sectional view of the motor-driven wind power generation system of the present invention. First, the mechanism of power generation will be described with reference to the drawings. The generator is a hybrid generator consisting of wind power and a motor, and is a wind turbine (1), a motor (2), and a continuous power supply battery system developed by our company, which is the power source. This is a power generation system that consists of (15) and alternately used generators (4), and automatically and continuously supplies power by power generation. Therefore, the wind turbine (1), which performs wind power generation, fixed the blades (5) of a radial type turbine in the shape of a belton turbine on the horizontal axis radially to the rotating shaft (6) of the turbine. A slit (8) opens in front of the built-in turbine (6) and the inertia force using centrifugal force like a flywheel by fitting a weight (7) that moves freely along the As a governor, the rear end of the wall (9) comes into contact with the inner wall of the casing (12) during strong winds and the frictional force controls the rotational speed of the turbine shaft (6). They also have a role. Also, by setting the partition (10) behind the upper half of the turbine rotation axis (6), the speed of the airflow due to the scroll in the casing (12) is increased. Also, it is a mechanism that generates electric power by connecting the rotor (11) of the generator (4) and the pinion that is automatically connected by being pushed by the overrunning clutch. Then the generated power is ignited This is a wind generator that supplies high-quality power by boosting the pressure according to the purpose by connecting it to a coil (13). First, when the natural wind penetrates the slit (8), the airflow slightly accelerated by the above calculation causes the plate (9) with the rear end of the ceiling of the casing (12) bent and the turbine (6) to be bent. At the rear of the plate (10) behind the upper body, the turbine is rotated by wind force accelerated 10 times or more by the tensile force generated by the vortex generated by the differential pressure, and at the same time, the eddy current after the plate (10) This reverses the direction of the air flow, which in turn pushes the rotating blades of the lower part of the turbine to increase the rotational force, and the air flow that rises along the bottom plate of the casing (12) immediately after the slit (8) This mechanism is directed toward the tip (14) that bends inward and protrudes, merges with the wind that has newly entered through the slit (8), and presses the turbine blade (5) to generate power. Next, while the natural wind does not reach the number of revolutions required for power generation by the sensor that measures the number of revolutions of the turbine (6), the mechanism automatically switches to power generation by driving the motor (2) instead. If a rechargeable lead-acid battery (15) is used as its power source, electrodes are installed in each case stacked in three layers, and adjacent moving spaces can be used. Four cases are built in as a unit of one box, and a mini motor is installed in the box so that it can circulate right and left and up and down automatically by rotating clockwise and move automatically. First, the cases are stacked vertically on top of each other with the battery cell interposed between them, and they penetrate each other with small holes. Through the upper case containing dilute sulfuric acid, and drop the electrolyte into the battery cell. In the battery cell, a generated liquid is generated as the chemical reaction to generate power proceeds. However, the battery cell is housed in the lower case and combined with the electrolyte from the drip from above, the chemical reaction involving discharge without diluting the concentration. The power is efficiently generated until the active material of the electrode is dissolved. When power generation is completed, the case moves to the adjacent room in the box, and the surplus power generated by the wind power or the surplus power transmitted at night causes the reverse current to flow, and the battery is charged and returned to the original battery cell. The case itself circulates and returns to its original position. Even in other cases, each function is restored and returned to the original position at the same time. Then, power is continuously supplied as a battery to enable power generation by continuous driving of the motor. Even if 10 boxes are arranged in series, it does not take up much space and costs only about 110th of the conventional propeller type wind power generator, so the power generation performance is almost the same. Assuming that it is to be assembled as a set of one generator, if it is installed in one set of four sets, it will be comparable to the maximum power generation performance of the conventional propeller generator 1, OOO kWH, and cost Is 1 to 4 and the total long-term power generation is about 4 times. And it is completely maintenance-free and can be opened as a new dedicated power station in a factory or building, etc. as a dedicated circuit of a completely different circuit from the conventional external power supply as a main power source. It also plays a role of rudder by noise prevention by the casing and the flag and the slit.
