DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1-11As shown, in this embodiment, a wind meter bracket is provided, comprising a base 1, a workpiece mounting rod 2, and a limit assembly. The workpiece mounting rod 2 is hinged to the base 1, and a workpiece mounting position is provided on the workpiece mounting rod 2. A workpiece such as a wind meter can be installed through the workpiece mounting position. The limit assembly comprises a sliding pair, a sliding pair locking member, and a fixed block 3. The sliding pair can be locked by the sliding pair locking member. The fixed block 3 is provided on the base 1. Preferably, the fixed block 3 is fixedly connected to the base 1. A gap is provided between the fixed block 3 and the workpiece mounting rod 2. The gap between the fixed block 3 and the workpiece mounting rod 2 allows the workpiece mounting rod 2 to move freely without causing interference when the workpiece mounting rod 2 moves. The sliding pair comprises a sliding member 4 and a guide member 5. The guide member 5 is connected to the fixed block 3; the guide member 5 can be supported by the fixed block 3; and the fixed block 3 can be rotatably connected to the guide member 5. The end of the slide 4 is connected to the workpiece mounting rod 2. Preferably, the slide 4 is fixedly connected to the workpiece mounting rod 2 and is connected to the side wall of the workpiece mounting rod 2. The slide 4 can drive the workpiece mounting rod 2 to move synchronously while rotating. A guide rod 6 is provided on the guide member 5. Preferably, the guide rod 6 is fixedly connected to the guide member 5. An arcuate chute 7 is provided on the slide 4, and the center of the arcuate chute 7 coincides with the hinge center of the workpiece mounting rod 2 on the base 1. The end wall of the arcuate chute 7 can abut against the guide rod 6, and the arcuate chute 7 can slide along the outer wall of the guide rod 6.

[0026] Working Principle: Because the workpiece mounting rod 2 is hinged to the base 1, it can rotate on the base 1. Simultaneously, the workpiece mounting rod 2 is fixedly connected to the slider 4, which slides along the guide rod 6 via an arcuate slot 7, forming a sliding pair with the guide member 5. To install the Cobra Anemometer in the workpiece mounting position on the workpiece mounting rod 2, first adjust the position of the base 1 according to the preset rotation direction of the workpiece mounting rod 2, placing the base 1 in the preset position. As the workpiece mounting rod 2 rotates, the locking member of the sliding pair is locked in the unlocked position, allowing the slider 4 to slide freely along the guide rod 6. The workpiece mounting rod 2 is controlled to rotate along the preset rotation direction on the base 1. At the same time, the workpiece mounting rod 2 can drive the slide 4 to slide synchronously along the guide rod 6, that is, the guide rod 6 can guide the movement of the slide 4 and the workpiece mounting rod 2, ensuring that the workpiece mounting rod 2 can accurately rotate along the preset rotation direction. When the workpiece mounting rod 2 is rotated into position, the sliding sub-locking member is controlled to be in the locking position. The sliding sub-locking member can be used to press the slide 4 tightly to prevent the slide 4 from sliding on the guide member 5, so that the workpiece mounting rod 2 is stably in the preset position. A wind meter is provided on the workpiece mounting position of the workpiece mounting rod 2. The flexible, precise and stable rotation of the workpiece mounting rod 2 on the base 1 can effectively adjust the position of the wind meter, with high flexibility and a large adjustment range, effectively realizing the measurement of the wind attack angle.

[0027] In one embodiment, the guide rod 6 can pass through the arc-shaped slide groove 7, and the sliding auxiliary locking member includes a locking nut 8. The portion of the guide rod 6 protruding from the arc-shaped slide groove 7 is provided with an external thread, and the external thread is threadedly connected to the locking nut 8, so that the locking nut 8 can be connected to the guide rod 6. When the locking nut 8 is in the locking position, the locking nut 8 in the locking position can tightly abut against the sliding member 4, locking the sliding member 4 so that the sliding member 4 cannot slide relative to the guide member 5. The locking nut 8 is unscrewed outward on the external thread of the guide rod 6, and the locking nut 8 is in the unlocking position, so that the locking nut 8 is out of contact with the sliding member 4, and the sliding member 4 can now slide freely along the guide rod 6. Preferably, an anti-slip structure can also be provided at the end of the sliding member 4 facing the locking nut 8 to ensure that the locking nut 8 can stably maintain the sliding member 4 in the locked position.

[0028] In one embodiment, the hinge device between the workpiece mounting rod 2 and the base 1 is a spherical universal joint, which includes a ball sleeve and a hinge ball 9, and the hinge ball 9 is fixedly connected to the workpiece mounting rod 2. The spherical universal joint is a hinge method in the prior art.

[0029] In one embodiment, the sliding member 4 and the guide member 5 are both arc-shaped structures; and the center of the guide member 5 coincides with the rotation center of the workpiece mounting rod 2 on the base 1. The center of the sliding trajectory of the sliding member 4 also coincides with the rotation center of the workpiece mounting rod 2. That is, the center of the sliding member 4 at any position coincides with the rotation center of the workpiece mounting rod 2 on the base 1. In the same limiting assembly, the radius of the sliding member 4 and the guide member 5 are consistent. The guide member 5 is tangent to the fixed block 3. Preferably, the outer end face of the guide member 5 is connected to the inner end face of the fixed block 3, and then the outer end face of the guide member 5 is tangent to the inner end face of the fixed block 3. When the sliding member 4 slides along the guide member 5, the sliding member 4 will not interfere with the guide member 5. Preferably, the fixed block 3 is perpendicular to the base 1, and the guide member 5 is connected to and tangent to the side of the fixed block 3 away from the base 1. The plane where the sliding member 4 is located is parallel to the plane where the guide member 5 is located. The sliding member 4 is a quarter arc. When the axis of the workpiece mounting rod 2 is perpendicular to the base 1, the guide rod 6 can be located in the middle of the arc-shaped slide groove 7, so that the sliding member 4 has a large sliding margin in both positive and negative directions on the guide member 5.

[0030] In one embodiment, the guide member 5 is rotatably connected to the fixed block 3, and one end of the guide member 5 is connected to the rotating shaft 10. The fixed block 3 is provided with a through hole for rotatably connecting to the rotating shaft 10. Preferably, a bearing for supporting the rotating shaft 10 is provided in the through hole, and the rotation center of the rotating shaft 10 is horizontally aligned with the rotation center of the workpiece mounting rod 2. At the same time, the rotation center of the rotating shaft 10 can also be adaptively adjusted according to actual conditions. The guide member 5 is fixedly connected to the rotating shaft 10, and the guide member 5 can synchronously drive the rotating shaft 10 to rotate when rotating. A threaded hole is provided on the fixed block 3, and the threaded hole can pass through the through hole and the outside. One end of the threaded hole can be connected to the rotating shaft 10, and the other end extends to the outside and is provided with a screw-in opening, through which the locking bolt can be screwed into the threaded hole. When the locking bolt is fully screwed into the threaded hole, it is in the locked position. At this point, the locking bolt can tightly abut the rotating shaft 10, locking the rotating shaft 10 through the locking bolt, preventing the rotating shaft 10 from rotating on the fixed block 3. At this point, the guide member 5 cannot rotate and is in a locked state. When it is necessary to rotate the rotating shaft 10 on the fixed block 3, the locking bolt can be simply unscrewed from the threaded hole. At this point, the guide member 5 is in an unlocked state. Preferably, an anti-slip structure can be provided on the outer end wall of the rotating shaft 10 to cooperate with the locking bolt to ensure the stability of the locked state.

[0031] In this embodiment, there are multiple limit assemblies, and the first limit assemblies 11 and the second limit assemblies 12 are limit assemblies among the multiple limit assemblies, that is, the limit assemblies include the first limit assemblies 11 and the second limit assemblies 12. The rotating shaft 10 in the first limit assemblies 11 and the rotating shaft 10 in the second limit assemblies 12 are both horizontally aligned with the rotation center of the workpiece mounting rod 2.

[0032] During operation, the first limiting assembly 11 or the second limiting assembly 12 is locked. That is, when the guide member 5 in the first limiting assembly 11 is locked, the guide member 5 in the second limiting assembly 12 is unlocked, and the guide member 5 in the second limiting assembly 12 can rotate on the fixed block 3. When the guide member 5 in the second limiting assembly 12 is locked, the guide member 5 in the first limiting assembly 11 is unlocked, and the guide member 5 in the first limiting assembly 11 can rotate on the fixed block 3.

[0033] Specifically, by screwing the locking bolt in the first limit assembly 11 into the threaded hole, the rotating shaft 10 in the first limit assembly 11 is locked by the locking bolt, so that the guide member 5 of the first limit assembly 11 is in a locked state, and at the same time, the guide member 5 of the second limit assembly 12 is in an unlocked state on the corresponding fixed block 3, and the guide member 5 on the second limit assembly 12 can rotate relative to the fixed block 3; the locking nuts 8 of the first limit assembly 11 and the second limit assembly 12 are both in the unlocked position, and the locking nuts 8 do not abut against the sliding member 4, that is, the sliding pairs of the first limit assembly 11 and the second limit assembly 12 can slide freely. When the base 1 is in the preset position, the preset rotation direction of the workpiece mounting rod 2 is: the sliding member 4 in the first limit assembly 11 slides along the guide rod 6.

[0034] The workpiece mounting rod 2 is controlled to rotate in a preset direction, and the sliding member 4 in the first limiting assembly 11 slides along the guide member 5; driven by the workpiece mounting rod 2, the guide member 5 in the second limiting assembly 12 rotates on the corresponding fixed block 3 via the rotating shaft 10; at the same time, the sliding member 4 in the second limiting assembly 12 can slide relative to the guide member 5. When the workpiece mounting rod 2 is rotated to the preset position, the locking nut 8 of the first limiting assembly 11 is screwed into the locking position to lock the sliding member 4 and the guide member 5 of the first limiting assembly 11. At the same time, the locking nut 8 of the second limiting assembly 12 is screwed into the locking position to lock the sliding member 4 and the guide member 5 in the second limiting assembly 12. At the same time, preferably, the locking bolt on the second limiting assembly 12 is screwed into the threaded hole to lock the rotating shaft 10 and the fixed block 3 on the second limiting assembly 12. During this process, when the workpiece mounting rod 2 rotates, the first stopper assembly 11 and the second stopper assembly 12 can jointly guide and limit the rotation direction of the workpiece mounting rod 2, so that the workpiece mounting rod 2 can accurately rotate in the preset rotation direction. At the same time, when the workpiece mounting rod 2 reaches the preset position, the first stopper assembly 11 and the second stopper assembly 12 can jointly support the workpiece mounting rod 2, ensuring the stability of the position of the workpiece mounting rod 2.

[0035] Furthermore, during operation, the locking bolts in the first and second position-limiting assemblies 11, 12 can be unscrewed from the bolt holes, thereby unlocking the guide members 5 in the first and second position-limiting assemblies 11, 12. When the workpiece mounting rod 2 is moved, the rotating shafts 10 of the first and second position-limiting assemblies 11, 12 can be driven to move synchronously. With the cooperation of their respective sliding pairs, the position of the workpiece mounting rod 2 can be effectively and stably adjusted.

[0036] In one embodiment, in order to ensure that the guide member 5 can be stably positioned in a vertical state and that the plane on which the guide member 5 is located can be stably maintained perpendicular to the base 1, pin holes can be provided on the guide member 5 and the fixed block 3. When the guide member 5 and the fixed block 3 are locked, and the guide member 5 is maintained perpendicular to the base 1, the pin holes in the guide member 5 and the fixed block 3 are aligned, and a latch can be simultaneously inserted into the pin holes on the guide member 5 and the fixed block 3. At this time, the guide member 5 is fixedly connected to the fixed block 3. When the guide member 5 and the fixed block 3 are unlocked, it is only necessary to remove the latch from the pin hole. Preferably, when the limit assembly is set as only one group, the guide member 5 and the fixed block 3 are always in a locked state.

[0037] In one embodiment, during the rotation of the rotating shaft 10, other locking methods can be used to lock the rotating shaft 10 to the fixed block 3. For example, retractable ratchets are provided on the rotating shaft 10 of the first and second stopper assemblies 11 and 12, and ratchet slots capable of engaging with the retractable ratchets are provided on the inner sidewalls of the through hole of the fixed block 3. The ratchet slots are evenly and densely arranged along the inner sidewalls of the through hole. When the guide member 5 drives the rotating shaft 10 to rotate to a predetermined position, the retractable ratchets on the rotating shaft 10 can be controlled to rotate out, so that the retractable ratchets on the rotating shaft 10 engage with the ratchet slots on the fixed block 3, thereby fixing the rotating shaft 10 and the guide member 5 together. The rotating shaft 10 and the guide member 5 can be locked in real time during rotation, thereby effectively fixing the rotating shaft 10 in a specific rotational position. When the rotating shaft 10 rotates normally, the retractable ratchets retract into the interior of the rotating shaft 10 and do not interfere with the fixed block 3. The ratchet-ratchet slot matching structure can support and limit the guide member 5. The specific structures of the telescopic ratchet and the ratchet slot are both prior art.

[0038] In this embodiment, the number of the first limit assemblies 11 and the second limit assemblies 12 are both two, the two first limit assemblies 11 are relatively arranged on both sides of the workpiece mounting rod 2, the two second limit assemblies 12 are relatively arranged on both sides of the workpiece mounting rod 2, and the first limit assemblies 11 and the second limit assemblies 12 are alternately distributed in the peripheral direction of the workpiece mounting rod 2. At this time, the number of fixed blocks 3 is four in total, and the base 1 can be set to a "cross-shaped" structure, and each fixed block 3 is respectively set on the four sides of the "cross-shaped" structure. The connecting line of the relative first limit assemblies 11 intersects with the connecting line of the relative second limit assemblies 12. Preferably, the first limit assemblies 11 and the second limit assemblies 12 are evenly arranged in the peripheral direction of the workpiece mounting rod 2, and the connecting line of the relative first limit assemblies 11 is perpendicular to the connecting line of the relative second limit assemblies 12.

[0039] In this embodiment, the first stop assembly 11 is connected to a first collar 13. Preferably, the sliding member 4 in the first stop assembly 11 is connected to the side wall of the first collar 13, and the two are connected by welding. The first collar 13 is sleeved on the outside of the workpiece mounting rod 2. The first collar 13 is tightly sleeved with the workpiece mounting rod 2. The second stop assembly 12 is connected to a second collar 14, which is tightly sleeved on the outside of the workpiece mounting rod 2. The first collar 13 is located on the side of the second collar 14 away from the base 1. The size of the first stop assembly 11 is larger than that of the second stop assembly 12.

[0040] In one embodiment, the anemometer bracket includes a vertical support rod 15 and a crossbeam 16. Preferably, the position of the crossbeam 16 on the vertical support rod 15 is adjustable, thereby changing the height of the crossbeam 16 and realizing the measurement of wind fields at different height layers. The vertical support rod 15 is also a telescopic structure, and the length of the vertical support rod 15 can be adjusted, thereby increasing the adjustable range of the height of the crossbeam 16. At the same time, the crossbeam 16 is also a telescopic structure, and the length of the crossbeam 16 can be adjusted. At the same time, the distance between the vertical support rods 15 arranged at both ends of the crossbeam 16 can also be adjusted synchronously to adapt to terrains of different sizes and widths. A guide rail 17 is provided on the crossbeam 16, and the extension direction of the guide rail 17 is parallel to the axis of the crossbeam 16. The base 1 is slidably connected to the guide rail 17 through a slider 18. The sliding direction of the slider 18 is parallel to the axis of the crossbeam 16. Preferably, the slider 18 includes a main body 19 and an adjusting portion 20. The adjusting portion 20 is threadedly connected to the main body 19 via an adjusting bolt 21. By controlling the adjusting bolt 21 to be screwed in and out of the main body 19, the distance between the main body 19 and the adjusting portion 20 can be controlled. Simultaneously, the main body 19 and the adjusting portion 20 together define a slot 31, through which the slider 18 is slidably engaged with the guide rail 17. When the main body 19 and the adjusting portion 20 abut, the slot 31 defined by the main body 19 and the adjusting portion 20 engages with the guide rail 17. When the adjusting portion 20 is moved away from the main body 19 by controlling the adjusting nut, the slot 31 defined by the main body 19 and the adjusting portion 20 can be simultaneously enlarged, allowing the slider 18 to disengage from the guide rail 17.

Preferably, the base 1 is rotatably connected to the main body 19 of the slider 18, and the rotation axis of the base 1 is preferably in a vertical position. The rotation axis of the base 1 is perpendicular to the sliding path of the slider 18. Furthermore, to lock the base 1 and the slider 18, a slider threaded hole is also provided on the slider 18. The slider threaded hole can be connected to the base 1, and a base locking bolt is connected to the slider threaded hole. The base locking bolt can be used to lock the base 1 and the slider 18.

[0042] In one embodiment, the workpiece mounting rod 2 includes a slide bar 22 and a sleeve 23. The sleeve 23 is sleeved on the outside of the slide bar 22 and is slidably connected to the slide bar 22. The workpiece mounting position is set on the slide bar 22, and a fixing button 24 is set on the sleeve 23, which can fix the slide bar 22. When it is necessary to adjust the extension length of the slide bar 22 from the sleeve 23, it is only necessary to press the fixing button 24 to adjust the extension length of the slide bar 22, and then release the fixing button 24. The fixing button 24 will return to its original position, fixing the slide bar 22 on the sleeve 23. A scale mark is set on the slide bar 22, and the extension amount of the slide bar 22 in the sleeve 23 can be read through the scale mark.

[0043] In this embodiment, the portion of the slide bar 22 extending from the sleeve 23 is connected to a rotating member 25. The rotating member 25 is rotatably connected to the slide bar 22, and the rotation axis of the rotating member 25 coincides with the axis of the slide bar 22. The workpiece mounting position is provided on the rotating member 25. A Cobra anemometer can be mounted on the workpiece mounting position, and the position of the Cobra anemometer can be adjusted by controlling the rotation of the rotating member 25 on the slide bar 22.

[0044] In one embodiment, the base 1 , the workpiece mounting rod 2 and the limiting assembly can form a workpiece adjusting member. There can be multiple workpiece adjusting members, and each of the members is slidably connected to the guide rail 17 on the beam 16 via a slider 18 .

[0045] In one embodiment, a positioning plate 26 is connected to the sleeve 23. Preferably, the number of positioning plates 26 is set to two, and the two positioning plates 26 are perpendicular to each other. A slope measuring instrument is provided in any positioning plate 26, and the slope measuring instrument includes an angle scale 27 and a level 28. Preferably, angle scales 27 are provided on two opposite sides of the positioning plate 26. Specifically, one angle scale 27 directly faces the workpiece mounting rod 2; the other angle scale 27 faces away from the workpiece mounting rod 2; the angle scale 27 is rotatably connected in the positioning plate 26, and the level 28 is rotatably connected to the angle scale 27; the level 28 can freely rotate 360 ​​degrees in the angle scale 27, and the angles of the workpiece mounting rod 2 in the horizontal and vertical directions can be measured through the angle scale 27, so as to achieve the purpose of measuring wind at any wind direction angle and wind attack angle. Specifically, the angle ruler 27 can be used in conjunction with the spirit level 28. The rotation direction of the workpiece mounting rod 2 is first preset, and the workpiece mounting rod 2 is controlled to rotate on the base 1 along the preset rotation direction. For example, if the workpiece mounting rod 2 is rotated to a position 10° in the preset direction, if the bubble in the spirit level 28 deviates from the horizontal position, the workpiece mounting rod 2 is then controlled to be adjusted in pitch until the bubbles in both spirit levels 28 are in the horizontal position, thereby allowing the workpiece mounting rod 2 to be effectively and accurately rotated to the 10° position. The combined use of the spirit level 28 and the angle ruler 27 can accurately adjust the position of the workpiece mounting rod 2, ensuring that the workpiece mounting rod 2 can effectively deflect the preset angle. When the adjustment angles of both spirit levels 28 are 0° and the bubbles are centered, it indicates that the Cobra wind gauge on the workpiece mounting rod 2 is completely horizontal. The positioning plate 26 is mounted on the workpiece mounting rod 2 via a locking ring 29. A locking ring bolt 30 is provided on the locking ring 29. The positioning plate 26 can be fixed by tightening the locking ring bolt 30 on the locking ring 29, and the positioning plate 26 can be removed by loosening the locking ring bolt 30. In addition, the two positioning plates 26 can be connected by a hinge for easy storage.
