Description

A slide rail type multi-stage vertical wind power generation device

technical field

The invention relates to the technical field of wind power generation, in particular to a slide rail type multi-stage vertical wind power generation device.

Background technique

The available resources on the earth are decreasing day by day. With the increasing awareness of environmental protection, the utilization and development of renewable energy has been paid more and more attention by countries due to the characteristics of clean energy and low greenhouse gas emissions. Among them, solar power generation and wind power generation are the most important.

Wind turbines are distinguished by the direction of the rotation axis of the impeller, which can be divided into two categories: horizontal axis type and vertical axis type. At present, the horizontal axis wind turbine is still the mainstream form in the domestic and foreign markets. However, the horizontal axis wind turbine has great shortcomings. For example, the horizontal axis wind turbine has a high installation height and occupies a large space. It needs a yaw system facing the wind, which has poor wind resistance, high noise during operation, and high starting wind speed (generally more than 3.5 m/s). Compared with the horizontal axis wind turbine, the vertical axis wind turbine can adapt to any wind direction, the installation height is lower, and it can also be arranged in one piece, taking up less space; in addition, the heavy components (generator, gearbox, etc.) are installed at the center of gravity Low noise, good overall stability and wind resistance; low noise from the generator during operation, and low starting wind speed (about 2 m/s). Therefore, in recent years, vertical axis wind turbines have attracted more and more attention.

The blades of vertical axis wind turbines rotate slowly, and usually require a large wind receiving area to obtain sufficient wind kinetic energy, so the size and weight of the blades are relatively large, especially for larger power units. When the height of the blade increases, the wind resistance of the blade becomes worse, the shaft size of the blade needs to be increased, and the support of the shaft needs to be strengthened; in this way, the weight and manufacturing cost of the fan blade are correspondingly increased, and the requirements for the support shaft are also increased. It is more difficult to install, and moreover, when the multi-layer blades rotate at the same time, the centrifugal force generated is large, which is easy to cause damage to the impeller shaft. It can be seen from the above: under the condition of ensuring sufficient wind area, how to ensure that the vertical blades of the vertical axis wind turbine are stably arranged on the vertical axis is the face of the design, manufacture and installation of the blades of the larger power vertical axis wind turbine. The key problem is that there is no better solution so far, and especially on some islands, due to the strong wind, the entire device is easily overturned due to its insufficient weight, causing unnecessary losses.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a sliding rail type multi-stage vertical wind power generation device, which can increase the weight of the entire device, enhance the stability of the entire device, have better wind resistance, and increase the power generation.

In order to solve the above-mentioned technical problems, the present invention adopts the following scheme:

The wheel extends horizontally to the top surface of the annular support. The support arm can slide along the annular support with the impeller shaft as the center. The auxiliary generator is fixed on both sides of the support arm. The rotor of the auxiliary generator is in the same direction as the radial direction of the annular support. A circular block is fixed at the end of the ring, and the circular block is slidably connected to the top surface of the ring support. The outer side of the ring support is fixed with a support rod extending to the ground. The generator set at the bottom is connected to the base through a bearing.

Due to the adoption of the above technical solutions, the power generation device of the present invention mainly includes a base, an annular support and multiple sets of power generating sets. The base and multiple sets of power generating sets are arranged in the annular support, and the bottom generating set is connected to the base through bearings. , the base is used to stabilize the stability of each generator set. Multiple sets of the generator sets are connected in series from bottom to top through the transmission box, so that the overall footprint is small and the power generation efficiency is high. The generator set includes multiple support arms, impeller shafts and a blade fixed on the support arm, one end of the support arm is fixedly connected with the impeller shaft, a plurality of support arms are radially distributed in the circumferential direction of the impeller shaft, and one end of each support arm away from the impeller shaft is provided with a guide wheel and extends horizontally to the annular On the top surface of the bracket, all the support arms can slide on the annular support with the impeller shaft as the center, and the auxiliary generators are fixed on both sides of the support arms, which increases the weight of the whole device, thereby enhancing the stability and wind resistance of the present invention. The radial direction of the rotor is the same as that of the annular support. The end of the rotor is fixed with a circular block, and the circular block is slidably connected to the top surface of the annular support. The blades drive the support arm to slide on the annular support under the action of wind, and the support arm drives the auxiliary The generator rotates together, so that the circular block and the top surface of the ring support rub, and drive the rotor to rotate, so as to realize the power generation of the auxiliary generator, and in the case of strong wind, the friction between the circular block and the ring support can be reduced. The rotation speed of the support arm, a support rod extending to the ground is fixed on the side of the ring support, the support rod is used to support and stabilize the ring support, one end of the support arm is fixed on the impeller shaft, and the other end of the support arm is placed on the ring support through the guide wheel, In this way, the vertical load of the blade on the support arm is decomposed to the impeller shaft and the annular bracket at the same time, which reduces the force strength of the support arm, thereby reducing the risk of the support arm breaking due to the excessive vertical load brought by the blade. When the force strength is reduced, the overall structure of the support arm can be simplified and the self-weight of the support arm can be reduced, thereby saving the cost of construction. Moreover, the support arm can slide along the annular support with the impeller shaft as the center of the circle, so that when the wind force is small, the blades can also drive the support The arm rotates to realize the main power generation function, improve the linear speed of the support arm rotation, and then improve the power generation efficiency. weight, enhances the stability and wind resistance of the present invention.

Further, a bracket is fixed between any two adjacent support arms, a plurality of auxiliary generators are evenly distributed on the bracket in a fan shape, the rotor of the auxiliary generator is along the radial direction of the annular bracket, and the top surface of the annular bracket is provided with an annular groove track. , the circular block at the end of the guide wheel and the rotor is located in the groove track.

Due to the above technical solution, multiple generator sets are distributed on the bracket, which further increases the weight of the entire device, making the stability and wind resistance performance better. Falling, but also has a certain guidance for the guide wheel and the circular block.

Further, as a preferred technical solution, the total number of layers of the power generation group is at least two layers, and the blades on any two adjacent layers of power generation groups absorb wind energy in opposite directions. A generator is installed on the periphery of the transmission device; a lower bevel gear and an upper bevel gear are fixedly connected to the impeller shafts of two adjacent generating sets, respectively, and the upper bevel gear and the lower bevel gear are between the upper bevel gear and the lower bevel gear. A synchronous bevel gear is provided, and the synchronous bevel gears are meshed with the upper and lower bevel gears respectively. The synchronous bevel gear is rotatably connected with the box body.
