The main body rotates around the axis of the tower through the connecting part. The two sides of the main body can be flat. In order to achieve the best effect, the two sides of the main body are smooth arcs. The cross section formed from the tower to the two surfaces together tends to be an optimized drop-shaped structure. On the same horizontal plane, the shortest distance between the opening of the main body along the surface of the tower is less than the half circumference of the tower on the same horizontal plane. From the top of the tower to the base, the size of the main body changes according to the diameter of the tower, that is, the diameter of the tower increases, and the main body also increases in size to fit the tower, forming the best streamline shape, so that there will be no turbulence near the tower. , The tail of the main body is provided with a diversion protrusion. The tail of the main body has radial elasticity. The radial elasticity can reduce the influence of turbulent flow. There is a reinforcing bracket in the main body to connect the inner sides of the two sides, so that the two sides are connected and the shape is fixed. , The sides of the two sides close to the tower are stabilized, and the reinforcing brackets are parallel or inclined, and other structural shapes are not listed in this application. The two sides of the main body are symmetrical to each other.

A connecting part is provided between the tower tube and the main body. The main body rotates around the tower tube through the connecting part. The connecting part can be a bearing. The inner ring of the bearing is fixedly connected to the tower tube. The outer ring of the bearing is connected to the main body. The inner ring and the outer ring of the bearing can be Rotate each other to make the main body rotate around the tower. You can even use the surface of the tower to make a ring-shaped depression instead of the inner ring of the bearing, or the connecting part is to set a track on the tower, the track is fixed around the tower, and the main body is fixed with pulleys. The pulley rotates along the track, and at least two connecting parts are arranged along the main body from the top to the base, or the connecting parts can be a gear ring, which is fixed to the tower barrel, and a gear is fixed to the main body, such as two fixed to the main body. The side surface is close to the position of the tower, the gear bites the gear ring, and the rotation of the gear can drive the main body to rotate around the tower. On the contrary, the gear ring can be fixedly connected with the main body, such as fixed on the two sides of the main body close to the tower. Three gears are evenly distributed around the same horizontal plane of the tower. The gears and gear rings are matched with each other. Conical gears and gear rings can be used, which can provide axial and radial forces at the same time. The rotation of the gear drives the rotation of the gear ring, and the gear ring rotates. The main body is driven to rotate, and each connecting part is connected with two side ends of the main body close to the tower on the same horizontal plane.

It is most suitable to have at least three connecting parts along the tower from the top to the base. Because of this arrangement, there are at least three connecting positions between the main body and the tower. When the tower is deformed by external forces, the main body is Connected to the tower while providing support or pulling force.

The opening of the main body facing the tower tube can be provided with an arc-shaped surface, and two sides of the main body near the tower tube can be provided with strips made of flexible elastic material to close the gap between the main body and the tower tube.

The connection between the main body and the tower tube through the connection part is a limit connection, that is, after the connection part is installed in place, when the main body is subjected to external force in other directions, the main body cannot fall off from the installation position. For example, when the connection part of the bearing is used, the main body is receiving When the force is in the vertical direction, it cannot be displaced in the vertical direction of the tower, so deep groove ball bearings and other bearings whose inner and outer rings cannot be displaced in the axial direction of the bearing are required. At the same time, a blocking device to prevent the axial rotation of the inner and outer rings of the bearing can be added. For example, the brake device is installed between the inner and outer rings of the bearing to prevent the inner and outer rings from rotating each other, so that when the main body does not need to rotate, the main body is fixedly connected to the tower and cannot move in any direction, and the connection part is connected by rail At the time, the pulley connected to the main body also needs to adopt a structure that can limit the position. For example, at least two pulleys are used to clamp the track from different directions. This design prevents the main body from falling off the tower due to external force. At the same time, the pulleys can be braked. In this way, when the main body is not required to rotate, the pulley brakes, so that the main body is fixedly connected to the tower, and cannot move in any direction. Therefore, three connecting parts are preferably arranged along the main body from the top to the base to facilitate the tower and the tower. The transmission of power between subjects.

Compared with the surface of the tower tube, the bearing, track or gear ring is convex, grooved, or flat. A depression can be reserved on the surface of the tower to accommodate the track, bearing or gear ring, so that the surface of the tower tube remains unchanged after the track or bearing is installed. Plane, and the bearing can use rolling bearings, sliding bearings or magnetic suspension bearings.

The connecting part and the main body are provided with a groove-shaped beak at a position opposite to the tower. The opening of the beak faces the tower and is arranged from the top to the base of the tower. When the main body rotates, the beak is always located on the main body with the rotation of the connecting part. At the position opposite to the tower tube, the connecting part can be a bearing, the bearing inner ring is fixedly connected to the tower tube, the bearing outer ring is connected to the main body, and a groove-shaped beak is fixed on the bearing outer ring, and the opening of the pointed beak faces the tower tube , The pointed beak is located at the relative position of the main body and the tower tube, and can follow the outer ring of the bearing to rotate. The pointed beak rotates with the connecting part and keeps the position of the tower tube relative to the main body. The setting of the pointed beak is also suitable for track or ring gear, etc. Structure, the pointed beak and the main body are respectively connected with pulleys and rails. The main body and the pointed beak are connected by a connecting rod surrounding the tower. The distance between the pointed beak openings along the outer surface of the tower is less than the four-half circumference of the tower on the same level. One-half the length and small size of the pointed beak is beneficial to reduce the weight and cost of the pointed beak. The tip of the pointed beak is provided with a shunting protrusion. The arrangement of the pointed beak can have a shunting effect and further reduce resistance.

From the perspective of the cross section of the main body, the linear distance between the two ends of the opening on the side of the main body on the cross section of the main body is a, the vertical distance from the intersection of the main body side on the cross section of the main body to a is h, and the ratio of h to a is from The direction from the top to the base of the main body gradually decreases. The cross-section of the main body is relatively slender at the top, and the base is relatively thick and short. It is suitable for fast flow at the top and slow flow at the base. The connection between the two sides of the main body and the opening of the main body The ratio of the vertical distance h to the distance a between the two sides at the opening of the main body appears to gradually decrease along the top of the main body to the base. This ratio can also be designed according to different environments in different regions. This design can make The tower and the main body adapt to different flow rates, that is, the top flow rate is high, and the base flow rate is low.

The described tower tube is a tower tube of a wind power generator set, a TV tower, an anemometer tower, a water building, a land column pier, a land column column, or a communication tower.

The two sides of the main body can be made of a variety of materials. They are made of light-weight and anti-aging materials such as plastic, glass fiber reinforced plastic and carbon fiber. The use of transparent materials such as polymer materials, polycarbon fiber or PET plastic can increase the aesthetics. Even the two sides of the main body are ultra-thin. Made of tempered glass.

Another type of arrangement is that there is a wind related device between the tower rectifier and the generator nacelle. The wind related device can be purely mechanical. For example, a fixed connecting rod is set between the generator nacelle and the tower rectifier so that the two Synchronous movement can also be an electric control device, which uses a control circuit to connect to a related drive device. For example, the position information of the generator compartment is wired or wirelessly connected to the electric drive device of the tower rectifier device. The electric drive device can be installed in the main body.

The wind related device can also be installed in the connection This is related to the setting of the connecting part between the main body and the tower. When the connecting part is suitable for setting the driving device, a wind-related device is set between the generator nacelle and the connecting part, such as rails and pulleys in the connecting part. When a motor is installed in the pulley to drive the pulley to rotate, the signal of the wind-related device is connected with the motor in the pulley. The same applies to the connection of the bearing and the gear ring. The electronically controlled wind-related device can be equipped with a generator cabin and a tower. The tube rectifying device is in the same direction or the power generation cabin and the tower tube rectifying device are in different directions.

A vertical axis wind power generator includes an impeller connected to a generator nacelle, the impeller and the generator nacelle are vertical-axis wind generators, the generator nacelle is installed on the top of the tower, and the tower is provided with any one of the above Tower rectification device, the impeller is of resistance type, lift type or two combined type. The tower rectification device is installed in this wind generator to reduce the shaking of the tower and stabilize the operation of the impeller on the top of the tower and the generator cabin.

The operation process of the blades needs to be stable. The tower tube obstructs the wind and generates local turbulent flow. The blades passing through the turbulent flow will produce vibration and speed changes. A rectifying device is installed in the tower tube to reduce the tower tube’s impact on the wind, thereby reducing the tower tube. The impact on the blades, and at the same time, because the tower tube's resistance to the wind is reduced, the wind velocity is increased, which improves the running power of the blades and improves power generation efficiency.

The connecting portion may be provided with a damping device, such as a liquid damping device, a gear damping device, a magnet damping device, etc., and the main body can rotate smoothly through the damping action of the damping device.

And to clean the surface of the tower to prevent the tower from being polluted and corroded, affecting the structural strength, or too much dust affecting the normal use of the tower, you can also set up a separate cleaning device inside the main body, such as installing a pipe with many nozzles in the main body, The pipe extends from the top of the main body to the base. The pipe can be rotated with the main body. It can be connected to the high-pressure water source regularly from the lower end of the pipe. The surface of the tower can be cleaned by spraying. The pipe is fixed with the reinforcing bracket in the main body. When the surface of the tower is too dusty, the viscosity of the fluid on the surface of the tower increases.

The invention is suitable for, but not limited to, various fixed towers in fluids such as air and water.

Beneficial effect

The beneficial effect of the present invention is: adopting the tower rectifying device and the application device of the present invention, the main body is arranged on the tower, so that the main body rotates around the tower, so that the tower has a very low resistance to the fluid flow direction. The streamlined structure of the fluid reduces the impact of the fluid’s resistance on the tower; the present invention is close to the tower through the connecting part, and from the cross section of the tower, it forms a raindrop-shaped flow in the fluid with lower resistance than the original tower. The line structure, and because the main body can rotate around the tower, it can have a good drag reduction effect on fluids from different directions. Because the current research has found that the drag coefficient of the dolphin's body structure is smaller, so the shunting beak and the main body are set Cooperate and rotate the tower together to further reduce the flow resistance and balance the weight of the main body on both sides of the tower. The tail of the main body has elasticity to cushion the impact when the fluid changes direction. The diversion protrusion at the end of the main body can also increase the diversion effect. To reduce the impact of noise on the environment, the main body changes shape along the tower to adapt to the fluid flow rate at different positions. The components of the present invention can be installed after the tower is completed, or can be pre-installed in the tower, which is convenient and light in weight. , The main body’s tower is installed through the connecting part. Because the main body and the tower are installed in a limit position, both sides bear the external force together. As the tower load increases, its ability to withstand bending moments and forces in all directions also increases, even with external forces. The capacity is greater than the original capacity before the main body is not installed. The increase of the tower rectifier device in this application not only increases the power generation capacity of the wind turbine, but also can adjust the wind turbine feather and stop working under disaster conditions such as hurricanes. Reduce the impact of the hurricane tower, and when the tower undergoes lateral vibration along the vertical direction from the tower to the main body, due to the asymmetric structure of the main body of the present application on one side of the tower, the main body is offset on the tower On one side of the axis line, the main body is separated by the sharp beak on the opposite side of the tower. The size and weight are small. When the tower vibrates in this lateral direction, because the tower and the main body are connected by at least three connecting parts, the main body is not only helpful In addition to the ability of the tower tube to resist bending vibration, the main body will swing relative to the tower tube and cooperate with the damping device of the connecting part, so that the tower tube rectifier of the present application can play a balance and stabilizing effect, similar to the balance pendulum on the top of a tall building. Hammer, the swing of the main body relative to the tower can be passive or active. The passive swing is the swing of the main body caused by the above-mentioned tower vibration. The active swing is in the tower rectifier or the tower or nacelle. Related sensor detection, pre-control the main body to swing to resist the occurrence of vibration, and complete the system control, the vibration described in this application also includes the vortex-induced vibration generated by the fluid, these settings and functions are not reflected in the previous application.
