Description

Technical Field

[0001] The invention relates to the technical field of wind measurement towers, in particular to a self-supporting wind measurement tower which can be automatically installed and has no tower shadow effect. Background Art

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

[0003] In the actual measurement process, the wind direction changes continuously, and the area with less wind disturbance also changes continuously. If the anemometer is installed in a fixed manner, it will inevitably be affected by the wind disturbance. However, if a fully movable installation method is adopted, the tower stability will be insufficient.

[0004] Application No. CN201611103642.X discloses a wind shadow resistant wind tower, which is a circular tower with a wind measuring platform installed at the wind measuring height. The wind measuring platform and the tower are concentric discs that can rotate freely on the tower. Two anemometers are installed on the wind measuring platform, and a wind shield is installed on the lower surface of the wind measuring platform perpendicular to the line connecting the anemometers. The wind shield pushes the disc to select under the action of wind force, so that the anemometer can always be kept in the direction perpendicular to the main wind direction. However, the wind measuring tower is a circular tower, which is inconvenient to install on the one hand and has a high cost on the other.

[0005] Application No. CN202211506789.9 discloses a wind measuring tower that can reduce the tower shadow effect. The wind measuring tower is mainly composed of a tower frame, a driving device, a rotating device and a wind measuring device. The tower frame is divided into an upper frame and a lower frame. After the two halves of the frame are separated, a driving device can be installed therein. The driving device is engaged with the rotating device, and the rotating device is fixedly assembled with the wind measuring device. After the overall installation is completed, the driving device can drive the rotating device to move, thereby driving the wind measuring device to move. Under the control of the tower shadow judgment mechanism, the driving device can control the driving device to rotate or stop according to the changes in the main wind direction. However, this wind measuring tower cannot be automatically installed, and its stability is poor.

[0006] Therefore, how to realize a wind measurement tower that can be automatically installed without tower shadow effect and has high stability is an issue that needs further research at this stage. Summary of the invention

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. Insert 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 rotating bearing 257 is inserted into the base connecting rod 230, the tripod rolling wheel 241 on the first tower 240 is placed into the annular inner groove 211 and the annular outer groove 221 on the rotating groove 200. The snap ring 260 is fixed on the rotating groove 200, and the outer snap ring limiting boss 267 and the inner snap ring limiting boss 268 on the snap ring 260 clamp the tripod limiting boss 242 on the first tower 240, so that the snap ring 260 cannot move in the vertical direction. After assembly, the tripod rolling wheel 241 can roll freely in the annular inner groove 211 and the annular outer groove 221, so that the first tower 240 can rotate freely with the center of the base connecting rod 230 as the axis. Insert the tower main shaft secondary rod 252 and the tower main shaft head cone 253 on the tower main shaft 250 into the tower main shaft connection hole 286 on the previous tower main shaft 250. The tower main shaft head cone 253 is set to be small at the upper end and large at the lower end, mainly to facilitate the insertion of the tower main shaft head cone 253 into the tower main shaft connection hole 286. When the tower main shaft head cone 253 is inserted into the previous tower main shaft connection hole 286, the tower vertical rod fixing cone 255 is also inserted into the tower vertical rod connection hole 287 on the previous tower vertical rod 271. Start the small motor to rotate, so that the screws in the first motor installation box 274 are inserted into the tower vertical rod second fixing hole 275 and the tower vertical rod first fixing hole 256 and are fixed tightly. Similarly, the screws in the second motor installation box 279 are inserted into the tower main shaft second fixing hole 288 and the tower main shaft first fixing hole 254 and are fixed tightly. Through the above assembly, the upper and lower sections of the tower can be fixedly connected together. Insert the direction plate body 341 of the direction plate 340 into the direction plate fixing groove 312 on the direction plate fixing rod 311, and the direction plate fixing wedge 342 at the upper end of the direction plate 340 is stuck in the direction plate fixing groove 312, and the direction plate and the tower can be assembled together. Through the above assembly method, the installation of a self-supporting wind measurement tower without tower shadow effect is completed. During the installation of the tower body, various wind measurement equipment can be first fixed to any one of the towers from the first tower 240 to the seventh tower 330, but must be fixed on the side of the tower main shaft 250 that is biased towards the second steering barrel 283.

[0040] After installation, under the influence of wind, the guide system 4000 drives the entire wind tower to rotate in the chute system 2000 on the base system 1000 with the tower main shaft 250 as the center, so that the triangular tip of the tower system 3000 is in the downwind direction of the wind. Since the wind measuring device is located on the side of the tower main shaft 250 that is biased towards the second steering barrel 283, it can be ensured that the wind measuring device will not be blocked by the tower body of the wind tower. In addition, since the triangular tip of the tower system 3000 is in the downwind direction of the wind, the windward surface of the tower in the entire main wind direction is smaller. At the same time, the farther the distance between the triangular tip and the tower main shaft 250 is, the better the stabilizing effect of the triangular tip on the entire tower. During the installation process, since small motors are provided in the first motor installation box 274 and the second motor installation box 279, the automatic installation of the wind tower can be achieved in combination with other auxiliary installation equipment.
