Description

Technical Field

[0001] This utility model relates to the field of millimeter-wave airspace measurement radar installation technology, and in particular to a millimeter-wave airspace measurement radar attitude angle adjustment structure. Background Technology

[0002] The blades are a crucial component of wind turbine generators, and their safety is critical to the overall safety of the turbine. A clearance radar is positioned at the blade tip to monitor the deformation in real time. If the wind force is too strong and the blade deformation becomes excessive, entering a dangerous zone, the turbine is slowed down or shut down in stages to prevent excessive blade deformation from colliding with the tower wall and causing damage, thereby improving the turbine's power generation efficiency.

[0003] Real-time monitoring of the clearance distance during blade operation ensures the normal operation of wind turbine generators. A stable and precise installation of the clearance radar allows for efficient and reliable real-time monitoring of the blade status, providing accurate data to the wind turbine generator's main control system.

[0004] The transmission and reception directions of the millimeter-wave airspace clearance radar beam are fixed relative to the radar itself. However, the installation positions of radars on different wind turbine generator sets are not uniform, and the mounting surfaces may be uneven. Therefore, it is necessary to adjust the radar's attitude so that its beam is oriented towards the clearance direction of the tower base center normal. The airspace clearance radar itself has a built-in gyroscope, and when adjusting the radar's attitude, the computer software can display the radar's attitude information in real time: pitch angle, roll angle, and yaw angle. The three angles displayed in real time are the radar's attitude angles.

[0005] A search revealed a patent document with publication number "CN221650608U" disclosing a millimeter-wave airspace clearance radar attitude angle adjustment structure. The structure includes a mounting base plate with a geometric bracket on it. A fixing block is mounted on the side of the bracket closest to the base plate via a mounting assembly. A spherical groove is located on the side wall of the fixing block closest to the base plate. A slide rail is located on the inner wall of the spherical groove, and a clamping block is slidably connected within the slide rail. The clamping block and the fixing block are connected by a fastening screw. A spherical structure is located within the spherical groove, and a universal rocker arm is located at the end of the spherical structure furthest from the groove. The universal rocker arm has multiple screw holes. This invention features a simple structure, easy assembly, and convenient angle adjustment. The attitude angle is adjustable in any direction, making it suitable for most installation environments. It significantly reduces installation and debugging cycles, further lowering labor costs.

[0006] In the aforementioned prior art, adjusting the attitude angle of a millimeter-wave airspace radar requires turning multiple fastening screws to make the adjustment, and then tightening the screws again after adjustment. This operation is cumbersome and results in a long adjustment time per operation, which is not conducive to quickly completing the adjustment of the millimeter-wave airspace radar attitude angle. Therefore, a millimeter-wave airspace radar attitude angle adjustment structure is needed. Utility Model Content

[0007] The purpose of this application is to provide an attitude angle adjustment structure for a millimeter-wave airspace measurement radar to solve the problems mentioned in the background art.

[0010] Several types of mounting brackets also have tightening components installed on their top plates to lift the adjustment seat upwards;

[0011] A limit component is installed on the upper end of the adjusting seat. When the adjusting seat is lifted to the highest point by the tightening component, the limit component limits the adjusting seat so that the adjusting seat cannot rotate.

[0012] The adjusting seat has an installation channel on one side, and a clamping block is slidably inserted into the installation channel. A locking component is installed on the side wall of the adjusting seat at the opening of the installation channel. The locking component is used to limit the clamping block after it is fully inserted into the installation channel, so that the clamping block is fixed without human operation. When the locking component is operated manually, it can release the limit on the clamping block.

[0013] Preferably, the upper end of the adjusting seat is rotatably connected to an adapter ring, and the adapter ring is movably sleeved on the outside of the limiting component;

[0014] The tightening assembly includes a guide slide rod and a first compression spring. The lower end of the guide slide rod slides through the top plate of the mounting bracket and is fixed to the upper end of the adapter ring. The upper end of the guide slide rod has a protruding end with a diameter larger than that of the guide slide rod.

[0015] The first compression spring is movably sleeved on the guide slide rod, and the upper and lower ends of the first compression spring are respectively fixed to the bottom surface of the protruding end of the guide slide rod and the upper surface of the top plate of the mounting bracket.

[0016] Preferably, the limiting component includes:

[0017] The bite plate has its top fixed to the bottom surface of the top plate of the mounting bracket. The lower end of the bite plate has downward protruding bite teeth, and multiple bite teeth are arranged in a circular array along the central axis of the bite plate.

[0018] The mating disc is fixed at the bottom and the top of the adjusting seat. The upper end of the mating disc is provided with a mating groove that matches the meshing teeth. Multiple mating grooves are also provided and correspond one-to-one with multiple meshing teeth.

[0019] Both the interlocking disc and the meshing disc have a circular hole in the middle for the operating column to pass through.

[0020] Preferably, the locking component includes:

[0021] The guide frame is fixed to the outside of the clamping block. The guide frame is a C-shaped frame, and the opening of the guide frame faces the side wall of the clamping block that is in contact with the mounting groove.

[0022] The guide frame has grooves on both its upper and lower inner walls.

[0023] The locking block is slidably embedded in the guide frame, and protrusions that match the sliding groove are formed on both the upper and lower sides of the locking block.

[0024] The limiting block is fixed to the side wall of the adjusting seat on one side of the installation channel opening. The limiting block has an insertion port for the locking block to be inserted on the side near the guide frame.

[0025] The second compression spring has its two ends fixed to the inner wall of the guide frame on the side away from the limit block and the side wall of the lock block on the side away from the limit block, respectively.

[0026] The lever plate is fixed to the side wall away from the clamping block.

[0027] Preferably, an anti-slip grip is fixed to the upper end of the operating column;

[0028] A limit clamp is movably installed at the lower end of the anti-slip grip bar. The limit clamp is engaged with the operating column. The upper end of the limit clamp abuts against the lower end of the anti-slip grip bar, and the lower end of the limit clamp abuts against the upper end of the top plate of the mounting bracket.

[0029] Preferably, the adjusting seat and the clamping block are both provided with a spherical cavity for accommodating the ball at the top of the universal rocker arm. A friction layer is provided on the arc-shaped wall of the inner wall of the spherical cavity formed by the clamping block, and the friction layer is interference-fitted with the ball at the top of the universal rocker arm.

[0030] In summary, the technical effects and advantages of this utility model are as follows:

[0031] 1. In this utility model, by setting up a tightening component, a limiting component, and a locking component, when it is necessary to adjust the attitude angle of the millimeter-wave airspace measurement radar, the operator only needs to push the operating column downward so that the adjusting seat overcomes the lifting effect of the tightening component, thereby releasing the limiting component's limiting effect on the adjusting seat. At this time, simply rotating the operating column will cause the adjusting seat to rotate accordingly, thereby adjusting the yaw angle of the radar body; or releasing the locking component's limiting effect on the clamping block and moving the clamping block so that the clamping block loses its limiting effect on the universal rocker arm, thereby allowing the universal rocker arm to rotate and roll on the adjusting seat, thereby adjusting the pitch angle and roll angle of the radar body;

[0032] Compared to existing technologies that require tightening multiple screws to limit or release the limit, this solution simplifies the adjustment process, enabling rapid adjustment of the attitude angle of the millimeter-wave airspace radar with high efficiency.

[0033] 2. In this utility model, by setting the limiting clamp, the limiting clamp can be clamped on the operating column after the adjusting seat is reset, and the upper end of the limiting clamp abuts against the lower end of the anti-slip grip rod, and the lower end of the limiting clamp abuts against the upper end of the top plate of the mounting bracket, thereby playing an axial limiting role on the operating column, avoiding the failure of the limiting component caused by the lowering of the operating column due to external force collision, and the self-movement of the radar body yaw angle, thus ensuring the stability of the equipment.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Example: Reference Figure 1-6 The millimeter-wave airspace clearance radar attitude angle adjustment structure shown includes a mounting plate 1 with a through hole in the middle, a mounting bracket 2 fixed on the mounting plate 1 by bolts, an adjustment seat 3 adjustablely mounted on the lower end of the top plate of the mounting bracket 2, and a radar body 5 corresponding to the position of the through hole in the mounting plate 1 adjustablely mounted on the lower end of the adjustment seat 3 by a universal rocker arm 4.

[0044] An operating column 6 is movably connected through the middle of the top plate of the mounting bracket 2, and the lower end of the operating column 6 is fixed to the upper end of the adjusting seat 3;

[0045] The top plate of the mounting bracket 2 is also equipped with a tightening assembly 7 for lifting the adjusting seat 3 upwards;

[0046] A limiting component 8 is installed on the upper end of the adjusting seat 3. When the adjusting seat 3 is lifted to the highest point by the tightening component 7, the limiting component 8 limits the adjusting seat 3 so that the adjusting seat 3 cannot rotate.

[0047] The adjusting seat 3 has an installation channel 32 on one side, and a clamping block 33 is slidably inserted into the installation channel 32. A locking component 9 is installed on the side wall of the adjusting seat 3 at the opening of the installation channel 32. The locking component 9 is used to limit the clamping block 33 after it is fully inserted into the installation channel 32, so that the clamping block 33 is fixed without human operation. When the locking component 9 is operated manually, it can release the limit on the clamping block 33.

[0048] Based on the above structure, when it is necessary to adjust the attitude angle of the millimeter-wave airspace measurement radar, the operator only needs to push the operating column 6 downward so that the adjusting seat 3 overcomes the lifting effect of the tightening component 7, thereby releasing the limiting component 8 from the limiting effect of the adjusting seat 3. At this time, simply rotate the operating column 6 to make the adjusting seat 3 rotate accordingly, thereby adjusting the yaw angle of the radar body 5; or release the limiting effect of the locking component 9 on the clamping block 33 and move the clamping block 33 so that the clamping block 33 loses the limiting effect on the universal rocker arm 4, thereby allowing the universal rocker arm 4 to rotate and roll on the adjusting seat 3, thereby adjusting the pitch angle and roll angle of the radar body 5.

[0049] Compared to existing technologies that require tightening multiple screws to limit or release the limit, this solution simplifies the adjustment process, enabling rapid adjustment of the attitude angle of the millimeter-wave airspace radar with high efficiency.

[0050] Furthermore, the upper end of the adjusting seat 3 is rotatably connected to an adapter ring 34, and the adapter ring 34 is movably sleeved on the outside of the limiting component 8;

[0051] The tightening assembly 7 includes a guide slide rod 71 and a first compression spring 72. The lower end of the guide slide rod 71 slides through the top plate of the mounting bracket 2 and is fixed to the upper end of the adapter ring 34. The upper end of the guide slide rod 71 has a protruding end with a diameter larger than that of the guide slide rod 71.

[0052] The first compression spring 72 is movably sleeved on the guide slide rod 71, and the upper and lower ends of the first compression spring 72 are fixed to the bottom surface of the protruding end of the guide slide rod 71 and the upper surface of the top plate of the mounting bracket 2, respectively.

[0053] With the guide slide rod 71 and the first compression spring 72, under normal conditions, the first compression spring 72 uses its own elastic force to lift the guide slide rod 71 upward, thereby causing the guide slide rod 71 to drive the adjusting seat 3 to rise. This ensures that the adjusting seat 3 always has an upward trend, allowing it to be limited by the limiting component 8. The limiting effect is more stable. At the same time, after the operator presses down on the adjusting seat 3 to adjust the yaw angle, the adjusting seat 3 will automatically rise and be limited by the limiting component 8 again, thus simplifying the reset operation steps when the operator adjusts the yaw angle.

[0054] Furthermore, the limiting component 8 includes:

[0055] The bite plate 81 is fixed at the top and bottom of the top plate of the mounting bracket 2. The lower end of the bite plate 81 has downward protruding bite teeth 811. Multiple bite teeth 811 are arranged and distributed in a circular array along the central axis of the bite plate 81.

[0056] The mating disc 82 is fixed at the bottom and the top of the adjusting seat 3. The upper end of the mating disc 82 is provided with a mating groove 821 that fits the meshing teeth 811. The mating groove 821 is also provided with multiple grooves and corresponds one-to-one with multiple meshing teeth 811.

[0057] Both the interlocking disc 81 and the mating disc 82 have a circular hole in the middle for the operating column 6 to pass through.

[0058] With the engagement plate 81 and the fitting plate 82 in place, when the adjusting seat 3 rises, the fitting plate 82 rises synchronously with the adjusting seat 3 and engages with the engagement teeth 811 through the fitting groove 821. This allows the fitting plate 82 to form a unified whole with the engagement plate 81 after rising, thereby achieving the effect of circumferentially limiting the adjusting seat 3 and preventing it from rotating. When the adjusting seat 3 descends, the engagement plate 81 and the fitting plate 82 separate, and the adjusting seat 3 can then be rotated to adjust the yaw angle.

[0059] Furthermore, locking component 9 includes:

[0060] The guide frame 91 is fixed to the outside of the clamping block 33. The guide frame 91 is a C-shaped frame, and the opening of the guide frame 91 faces the side wall of the clamping block 33 that is in contact with the mounting groove 32.

[0061] The guide frame 91 has grooves 911 on both its upper and lower inner sidewalls.

[0062] Locking block 92 is slidably embedded in guide frame 91, and both the upper and lower sides of locking block 92 have protrusions that are adapted to slide groove 911.

[0063] The limiting block 93 is fixed to the side wall of the adjusting seat 3 on the side of the opening of the mounting channel 32. The limiting block 93 has an insertion port 931 for the locking block 92 to be inserted on the side near the guide frame 91.

[0064] The second compression spring 94 has its two ends fixed to the inner wall of the guide frame 91 on the side away from the limiting block 93 and the side wall of the locking block 92 on the side away from the limiting block 93, respectively.

[0065] The lever 95 is fixed to the side wall of the locking block 92 away from the clamping block 33;

[0066] One side of the locking block 92 (referring to the side of the locking block 92 facing the limiting block 93 when the clamping block 33 is inserted into the mounting channel 32) is provided with a chamfer (not shown in the figure). The chamfer is adapted to the limiting block 93. That is, when the locking block 92 moves as the clamping block 33 is inserted into the mounting channel 32, the chamfer first contacts the side wall (side) of the limiting block 93, and during the movement, the locking block 92 slides away from the limiting block 93, squeezing the second compression spring 94.

[0067] By setting the locking component 9, when the clamping block 33 is inserted into the mounting channel 32, the chamfered part on one side of the locking block 92 first contacts the side wall of the limiting block 93, and during the movement, the locking block 92 slides away from the limiting block 93, squeezing the second compression spring 94 until the locking block 92 corresponds to the insertion port 931 of the limiting block 93 (at this time, the clamping block 33 is fully inserted into the mounting channel 32 and can hold the universal rocker arm 4 so that the position of the universal rocker arm 4 is fixed). Under the elastic force of the second compression spring 94, the locking block 92 pops out and enters the insertion port 931, thereby completing the limiting of the clamping block 33, that is, the position of the universal rocker arm 4 can be fixed, thus simplifying the fixing operation after adjusting the pitch angle and roll angle of the radar body 5;

[0068] When it is necessary to release the limit, simply squeeze the two levers 95 to move them away from the two limit blocks 93 (the two levers 95 are in a relative motion state), and the locking block 92 can be pulled out, releasing the limiting effect of the clamping block 33. This also makes it easier to adjust the pitch and roll angles of the radar body 5 again.

[0069] Furthermore, an anti-slip grip bar 61 is fixed to the upper end of the operating column 6;

[0070] A limiting clamp 21 is movably installed at the lower end of the anti-slip grip 61. The limiting clamp 21 is a three-quarter ring-shaped hoop made of PE or PVC material with a certain deformation capacity. The limiting clamp 21 is snapped onto the operating column 6. The upper end of the limiting clamp 21 abuts against the lower end of the anti-slip grip 61, and the lower end of the limiting clamp 21 abuts against the upper end of the top plate of the multi-type mounting bracket 2.

[0071] By setting the limiting clamp 21, after the adjusting seat 3 is reset (i.e. after the engagement plate 81 and the fitting plate 82 are closed), the limiting clamp 21 can be locked onto the operating column 6, so that the upper end of the limiting clamp 21 abuts against the lower end of the anti-slip grip 61, and the lower end of the limiting clamp 21 abuts against the upper end of the top plate of the mounting bracket 2, thereby playing an axial limiting role on the operating column 6, avoiding the failure of the limiting component 8 caused by the lowering of the operating column 6 due to external force collision, and the self-movement of the yaw angle of the radar body 5, thus ensuring the stability of the equipment.

[0072] Furthermore, the adjusting seat 3 and the clamping block 33 are both provided with a spherical cavity 31 for accommodating the ball at the top of the universal rocker arm 4. A friction layer 331 is provided on the arc-shaped wall of the inner wall of the spherical cavity 31 formed by the clamping block 33. The friction layer 331 is interference-fitted with the ball at the top of the universal rocker arm 4. By providing the friction layer 331, greater friction can be provided when the clamping block 33 clamps the ball at the top of the universal rocker arm 4, thereby improving the stability of the universal rocker arm 4.

[0073] The working principle of this utility model is as follows: In daily use, when it is necessary to adjust the attitude angle of the millimeter-wave airspace measurement radar, the operator only needs to push the operating column 6 downward, so that the adjusting seat 3 overcomes the lifting effect of the tightening component 7, thereby compressing the first compression spring 72. At the same time, the adjusting seat 3 and the mating plate 82 descend. After the biting plate 81 separates from the mating plate 82, the operator only needs to rotate the operating column 6 to make the adjusting seat 3 rotate accordingly, thereby adjusting the yaw angle of the radar body 5; or release the limiting effect of the locking component 9 on the clamping block 33, that is, squeeze the two levers 95 by hand, so that the two levers 95 move away from the two limiting blocks 93, thereby driving the locking block 92 to pull out the locking block 92. Then move the clamping block 33, so that the clamping block 33 loses the limiting effect on the universal rocker arm 4, thereby allowing the universal rocker arm 4 to rotate and roll on the adjusting seat 3, thereby adjusting the pitch angle and roll angle of the radar body 5.

[0074] Compared to existing technologies that require tightening multiple screws to limit or release the limit, this solution simplifies the adjustment process, enabling rapid adjustment of the attitude angle of the millimeter-wave airspace radar with high efficiency.

[0075] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
