Description

Technical Field

[0001] This invention relates to the field of wind measurement tower technology, and in particular to a self-supporting wind measurement tower that can be automatically installed without tower shadow effect. Background Technology

[0002] Currently, anemometer towers are mainly divided into two types: cylindrical towers and lattice structure towers, both of which produce a tower shadow effect. In cylindrical towers, the area of ​​least wind disturbance is usually located at a 45° angle to the wind direction. As for lattice structure towers, their airflow characteristics are more complex. The degree of wind disturbance on the tower is affected by the tower porosity, the damping effect of various components, and the distance between the anemometer and the tower. For a lattice structure anemometer tower with a wind thrust coefficient of 0.486, the direction of least wind disturbance is at a 90° angle perpendicular to the wind direction.

[0003] During actual measurements, wind direction constantly changes, and areas with minimal wind disturbance also shift. If a fixed installation method is used to mount the anemometer, it will inevitably be affected by wind disturbances. However, if a completely movable installation method is adopted, the tower stability will be insufficient.

[0004] Application number CN201611103642.X discloses a wind-shadow-resistant anemometer tower. The tower is a circular cylinder with an anemometer platform installed at the measurement height. The platform and tower are concentric discs that can rotate freely on the tower. Two anemometers are mounted on the platform, and a wind deflector is installed on the lower surface of the platform perpendicular to the line connecting the anemometers. The wind deflector, under the action of wind, pushes the disc to rotate, ensuring the anemometers remain perpendicular to the prevailing wind direction. However, the described anemometer tower is a circular cylinder, which is inconvenient to install and has a high cost.

[0005] Application number CN202211506789.9 discloses a wind measuring tower that can reduce the tower shadow effect. The wind measuring tower mainly consists of a tower frame, a drive device, a rotating device, and a wind measuring device. The tower frame is divided into an upper frame and a lower frame. The drive device can be installed in the two halves after separation. The drive device meshes with the rotating device, and the rotating device is fixedly assembled with the wind measuring device. After the entire assembly is completed, the drive device can drive the rotating device to move, thereby driving the wind measuring device. Under the control of the tower shadow determination mechanism, the drive device can be controlled to rotate or stop according to changes in the prevailing wind direction. However, this wind measuring tower cannot achieve automatic installation and has poor stability.

[0006] Therefore, how to achieve an automatically installable wind measurement tower with no tower shadow effect and high stability is a problem that needs further research at this stage. Summary of the Invention

[0028] 4. This invention adopts a modular design, dividing the wind measurement tower into multiple structurally similar isosceles triangular tower units. This effectively reduces the difficulty of installation and processing of the wind measurement tower, simplifies the installation process, and significantly reduces the production and installation costs of the wind measurement tower.

[0029] 5. The present invention uses a combination of base connecting rod and tower main shaft to form the rotating shaft of the wind measurement tower, and the rotating shaft is sleeved through the cone head of the base connecting rod and the cone head of the tower main shaft, which not only ensures that the rotating shaft has sufficient structural strength, but also reduces the difficulty of installation and production of the rotating shaft.

The guiding system 4000 mainly includes a directional plate 340, which provides torque for the rotation of the anemometer tower under wind force.

[0074] Insert the inner sliding groove fixing ring 213 on the inner sliding groove 210 into the inner rotating groove slot 103 on the base 100 and fix it tightly. Insert the outer sliding groove fixing ring 223 on the outer sliding groove 220 into the outer rotating groove slot 104 on the base 100 and fix it tightly. The rotating sliding groove 200 can then be fixedly installed on the base 100. Insert the base connecting rod fixing wedge 235 on the base connecting rod 230 into the tower main rod mounting hole 102 and fix it tightly. Fit the center of the tower main shaft rotating bearing 257 on the first tower 240 into the base connecting rod secondary rod body 232 on the base connecting rod 230, wherein the tower main shaft rotating bearing 257 is fixed in the bearing fixing frame 247. When the tower main shaft rotary bearing 257 is fitted onto the base connecting rod 230, the scaffold rollers 241 on the first tower 240 are placed into the inner annular groove 211 and the outer annular groove 221 on the rotary groove 200. The retaining ring 260 is fixed onto the rotary groove 200. At this time, the outer retaining ring limiting boss 267 and the inner retaining ring limiting boss 268 on the retaining ring 260 lock the scaffold limiting boss 242 on the first tower 240, preventing the retaining ring 260 from moving vertically. After assembly, the scaffold rollers 241 can roll freely in the inner annular groove 211 and the outer annular groove 221, thus allowing the first tower 240 to rotate freely about the center of the base connecting rod 230. Insert the secondary shaft body 252 and the head cone 253 of the tower main shaft 250 into the tower main shaft connection hole 286 on the previous tower main shaft 250. The reason for designing the head cone 253 with a smaller upper end and a larger lower end is to facilitate insertion into the tower main shaft connection hole 286. Simultaneously, the tower vertical rod fixing cone 255 is inserted into the tower vertical rod connection hole 287 on the previous tower vertical rod 271. Start the small motor to rotate, causing the screws in the first motor mounting box 274 to be inserted into and tightened in the second fixing hole 275 and the first fixing hole 256 of the tower vertical rod. Similarly, the screws in the second motor mounting box 279 are inserted into and tightened in the second fixing hole 288 and the first fixing hole 254 of the tower main shaft. Through the above assembly, the upper and lower tower sections can be fixedly connected together. Insert the directional plate body 341 of the directional plate 340 into the directional plate fixing groove 312 on the directional plate fixing rod 311. The directional plate fixing wedge 342 at the upper end of the directional plate 340 is engaged in the directional plate fixing groove 312, thus assembling the directional plate and the tower together. Through this assembly method, the installation of a self-supporting wind measurement tower without tower shadow effect can be completed. During the installation of the tower body, various wind measurement devices can be fixed in any one of the towers from the first tower 240 to the seventh tower 330, but they must be fixed on the side of the tower main shaft 250 biased towards the second steering barrel 283.

[0075] After installation, driven by the wind, the guide system 4000 rotates the entire wind measurement tower around the main shaft 250 within the sliding groove system 2000 on the base system 1000, ensuring that the triangular tip of the tower system 3000 is leeward. Because the wind measurement equipment is located on the main shaft 250, offset to one side of the second steering cylinder 283, it is ensured that the wind measurement equipment is not obstructed by the main tower body. Furthermore, since the triangular tip of the tower system 3000 is leeward, the windward surface of the tower is smaller in the prevailing wind direction. Simultaneously, the greater the distance between the triangular tip and the main shaft 250, the better the stability effect of the triangular tip on the entire tower. During installation, small motors are installed in the first motor mounting box 274 and the second motor mounting box 279, which, in conjunction with other auxiliary installation equipment, enable automatic installation of the wind measurement tower.
