Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a radar adjustment structure and a clearance monitoring device. Background Art

[0002] Wind turbines generally consist of towers, nacelles, and blades. Real-time monitoring of the clearance between the blades and the tower is of great significance to prevent tower sweep accidents. Clearance monitoring devices are commonly used in wind turbines. Their main structure includes radar, which emits detection waves to illuminate the blades and receives data returned by the blades to monitor the clearance between the blades and the tower.

[0003] During radar detection, the radar often receives too little data returned by the wind blades, resulting in large errors in clearance monitoring. The main reason is that the angle of the detection wave emitted by the radar is difficult to adjust, and some detection waves will be blocked by the tower and the cabin, resulting in a reduction in the effective detection waves acting on the wind blades. In addition, the tip of the wind blade is the smallest and farthest from the radar. When the detection wave emitted by the radar shines on the tip of the blade, less data is returned. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a radar adjustment structure and a clearance monitoring device which can adjust the angle of the radar transmitting detection wave and have a small clearance monitoring error.

[0005] The technical solution adopted by the present invention to solve the above problems is: a radar adjustment structure, comprising:

[0006] a substrate; and

[0007] an adjustment assembly, wherein the adjustment assembly is movably connected to at least one end of the substrate; the radar is disposed on the substrate or the adjustment assembly; the adjustment assembly includes at least one of an elevation angle adjustment portion and a deflection angle adjustment portion;

[0008] The elevation angle adjustment portion is configured to be rotatably connected to the substrate so as to adjust the elevation angle of the radar; the deflection angle adjustment portion is configured to be rotatably connected to the substrate so as to adjust the deflection angle of the radar.

[0009] Compared with the prior art, the present invention includes a base plate and an adjustment assembly movably connected to at least one end of the base plate, so that the base plate and the adjustment assembly can be adjusted in angle by movement. When the radar is installed on either the base plate or the adjustment assembly, the angle of the radar can be adjusted by movement. The adjustment assembly includes at least one of an elevation adjustment unit and a deflection adjustment unit. The elevation adjustment unit is configured to be rotatably connected to the base plate. When the elevation adjustment unit rotates relative to the base plate, the detection wave emitted by the radar is directed to the wind blade area above the blade tip. Compared with the blade tip, this area is larger in size and closer to the radar, thereby enabling the radar to obtain more return data, thereby reducing the clearance monitoring error. The deflection adjustment unit is configured to be rotatably connected to the base plate. When the deflection adjustment unit rotates relative to the base plate, the radar is deflected toward the tower side, so that the detection wave emitted by the radar avoids obstruction by the tower and the nacelle, thereby increasing the effective detection wave acting on the wind blade and reducing the clearance monitoring error. In addition, when the elevation adjustment unit and the deflection adjustment unit are simultaneously present, it is beneficial to further reduce the clearance monitoring error.

[0035] In actual use, the utility model includes a base plate 1 and an adjustment component 2 movably connected to at least one end of the base plate 1, so that the base plate 1 and the adjustment component 2 can change the angle by movement. When the radar 4 is set on one of the base plate 1 or the adjustment component 2, the angle of the radar 4 can be changed by movement; the adjustment component 2 includes at least one of an elevation adjustment part 21 and a deflection angle adjustment part 22; wherein the elevation adjustment part 21 is arranged to be rotatably connected to the base plate 1. When the elevation adjustment part 21 rotates relative to the base plate 1, the detection wave emitted by the radar 4 points to the wind blade area above the blade tip, and the relative Compared with the blade tip, this area is larger in size and closer to the radar 4, so that the radar 4 can obtain more return data, making the clearance monitoring error smaller; the deflection angle adjustment part 22 is configured to be rotatably connected to the substrate 1. When the deflection angle adjustment part 22 rotates relative to the substrate 1, the radar 4 deflects toward the side of the tower so that the detection wave emitted by the radar 4 avoids the obstruction of the tower and the cabin, thereby making more effective detection waves acting on the wind blade and the clearance monitoring error smaller; in addition, when the elevation angle adjustment part 21 and the deflection angle adjustment part 22 exist at the same time, it is beneficial to further reduce the clearance monitoring error.
