Description

Technical Field

[0001] This utility model relates to the field of propeller wind speed sensor technology, and in particular to a propeller wind speed sensor base stabilization bracket. Background Technology

[0002] Propeller-type wind speed sensors can sense and measure wind direction and speed in real time and accurately. They are usually fixed to vertical or horizontal mounting rods by their base. However, in actual engineering installation and application, traditional installation methods have obvious limitations.

[0003] Traditional installation methods typically involve directly fixing the sensor base to the top of the base using clamps or flanges, creating a "cantilever beam" structure. In continuous and variable natural wind fields, the aerodynamic forces acting on the sensor's wind cups and tail fins generate significant overturning moments, which are entirely borne by the connection points between the sensor bases. Over long periods, this can easily cause minute vibrations (swaying) or even plastic deformation of the connection structure. Utility Model Content

Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention.

[0020] Reference Figures 1-3 This embodiment provides a propeller wind speed sensor base stabilization bracket, including a clamping unit 1 including a clamping arm 11, a fixing plate 12 fixedly disposed at the rear end of the clamping arm 11, and a set screw 13 connected to the rear end of the fixing plate 12. The support unit 2 is located on one side of the clamp unit 1; the support unit 2 includes a slide rail 21 clamped inside the fixed plate 12, a slide plate 22 that slides with the slide rail 21, and a support block 23 connected to the bottom of the slide plate 22.

[0021] Furthermore, the clamping arm 11 is clamped to the outer periphery of the base 31; The slide plate 22 slides into the tail tube 32.

[0022] The clamping arm 11 includes a pair of arc-shaped pieces 111 symmetrically arranged on the left and right sides of the base 31, each of the two ends of the pair of arc-shaped pieces 111 having a connecting ear 112, and the rear end of the arc-shaped pieces 111 having a mounting surface 113 protruding.

[0023] Furthermore, the fixing plate 12 includes a plate body 121, a clamping part 122 protruding from the front end of the plate body 121, a through hole 123 penetrating the axis of the plate body 121, and a fixing post 124 fixedly connected to the rear end of the plate body 121.

[0024] Furthermore, the slide rail 21 includes a guide groove 211 opened along the length of the slide rail 21, a guide rail 212 fixedly disposed inside the guide groove 211, and limiting blocks 213 located at both ends of the slide rail 21.

[0025] Furthermore, the slide rail 21 also includes a fixing hole 214 that passes through its axis; The set screw 13 passes through the fixing hole 214 and fixes the slide plate 22.

[0026] Furthermore, the skateboard 22 includes a limiting end 221 at its upper end, a sliding part 222 protruding from the bottom of the limiting end 221, and a support part 223 protruding from the bottom of the sliding part 222.

[0027] In this embodiment, the clamping unit 1 is an assembly used to clamp the cylindrical base 31, and its main body has a C-shaped clamp structure. The clamping arm 11 is composed of two identical arc-shaped pieces 111 arranged symmetrically from left to right. At both ends of each arc-shaped piece 111 along its circumference, connecting ears 112 are formed by vertically folding outwards. The connecting ears 112 have coaxial bolt through holes. The two arc-shaped pieces 111 are pulled together by bolts passing through their connecting ears 112, surrounding and locking onto the base 31. A rectangular mounting surface 113 is fixed together at the rear ends of the two arc-shaped pieces 111. The gap between the mounting surface 113 and the clamping part 122 at the front end of the fixing plate 12 serves as the mounting space for the support unit 2. The slide rail 21 is fixed by the cooperation between the clamping part 122 and the mounting surface 113.

[0028] Preferably, the fixing plate 12 is a rectangular plate 121 of uniform thickness, with its front end facing the center of the clamping arm side. A forward-protruding clamping part 122 is milled into the front end, and the cross-section of the clamping part 122 is convex. A through hole 123 is vertically machined through the center of the plate 121. This through hole 123 is a threaded hole that engages with the set screw 13. Four sets of fixing posts 124 are threadedly connected to the end face of the plate 121. The fixing posts 124 fix the fixing plate 12 and the support unit 2 inside the clamping part 122 to the mounting surface 113, achieving a stable connection. After the fixing plate 12 is aligned with the mounting surface 113 of the two clamping arms 111 through the fixing posts 124 on its end face, it is rigidly connected by four corner bolts, so that the fixing plate 12 is installed parallel to the end face of the mounting surface 113.

[0029] Preferably, the set screw 13 is a standard fully threaded screw, with a butterfly or hexagonal knob welded to one end. Its thread matches the threaded hole of the through hole 123. By tightening the set screw 13, the support unit 2 is locked between the mounting surface 113 and the clamping part 122, thereby fixing the axial position of the slide rail 21.

[0030] Preferably, the support unit 2 is a linear sliding adjustment mechanism for providing a telescopic support arm to provide auxiliary support for the base 31 at the bottom of the propeller-type wind speed sensor, so as to avoid excessive stress at the bottom of the base 31 due to wind force, thereby improving installation stability and reducing structural fatigue.

[0031] The slide rail 21 is made of alloy profile and slides in conjunction with the clamping part 122 on its outer side. A rectangular guide groove 211 is milled into the upper surface of the slide rail 21 along its length. A guide rail 212 is fixedly embedded inside the guide groove 211. Limiting blocks 213 are fixed to both ends of the slide rail 21 with screws to limit the sliding range. Multiple sets of fixing holes 214 are linearly and vertically formed on the surface of the slide rail 21. These fixing holes 214 are smooth holes, allowing the set screw 13 to be screwed into the fixing hole and pressed against the wall of the slide plate 22 for locking.

[0032] Preferably, the sliding plate 22 is a long strip of aluminum alloy plate that slides in conjunction with the slide rail 21. Its upper end is a limiting end 221, which is used to fix the tail tube 32 of the propeller-type wind speed sensor above to rotate, preventing misalignment before installation or transportation. The sliding part 222 extends downward from the center of the lower surface of the limiting end 221, and its cross-sectional shape is complementary to the guide groove 211 of the slide rail 21. The support part 223 extends from one side of the bottom of the sliding part 222 with a hinged end, which is used to hinge the support block 23 so that the support block 23 lies horizontally on the mounting platform at the bottom of the base 31, and the support unit 2 is supported on the rear end of the base 31, thereby effectively sharing the bending moment of the wind load on the base.

[0033] Preferably, the support block 23 is a rectangular block hinged to one end of the support part 223, and its upper part is hinged to the support part 223 of the slide plate 22 by a pin.

[0034] The support base point is determined by adjusting the height of the clamp on the base 31. The slide plate 22 slides along the slide rail 21, driving the support block 23 to move to the preset position with the propeller-type anemometer tail cylinder 32. When the slide plate 22 is pulled upward, the limiting end 221 abuts against the bottom of the propeller-type anemometer tail cylinder 32, realizing the rotation and fixation of the tail cylinder, preventing the propeller-type sensor angle from shifting due to transportation vibration or installation process, thus preventing inaccuracy. When the slide plate 22 is pulled downward, the support block 23 rotates around the hinge point and fits against the bottom platform of the base 31. Finally, the set screw 13 is tightened to press the slide plate 22 firmly onto the mounting surface 113, thereby completely fixing the adjusted shape of the entire bracket and forming a rigid triangular support structure for the base 31, effectively suppressing tail swaying.

[0035] Reference Figures 3-4 As an optional embodiment, the limiting end 221 includes a positioning post 2211 and an arc-shaped block 2212 protruding from the outer periphery of the positioning post 2211; The bottom circumference of the tail tube 32 is provided with a slot 321 that matches the positioning post 2211.

[0036] In this embodiment, the anti-rotation connection between the limiting end 221 of the slide plate 22 in the support unit 2 and the sensor tail cylinder 32 provides axial support while restricting the circumferential rotation of the tail cylinder 32, ensuring the stability of the sensor pointer during transportation, installation and maintenance.

[0037] Preferably, the limiting end 221 is the positioning end at the top of the slide plate 22. The slide plate 22 is rotated and machined to form a round end, which can be a positioning post 2211. The top of the positioning post 2211 can be machined into a small-angle conical or spherical guide head for easy insertion. The tail tube 32 of the propeller-type wind speed sensor has a slot 321 at the bottom to cooperate with the limiting end 221. The arc-shaped block 2212 is an arc-shaped rib that surrounds the side of the slide plate 22 facing the base 31. The bottom of the arc-shaped block 2212 is fixed to the side of the slide plate 22 by welding, providing auxiliary support to one side of the base 31.

[0038] When it is necessary to fix the sensor position, slide the slide plate 22 upward along the slide rail 21 to the highest point. At this time, the limiting end 221 rises to directly below the bottom of the tail cylinder 32. Align it visually or by making slight movements, so that the axis of the positioning post 2211 coincides with the axis of the slot 321 at the bottom of the tail cylinder 32; then tighten the set screw 13 to securely lock the slide plate 22 onto the slide rail 21.

[0039] When the sensor needs to work normally, simply loosen the top screw 13, slide the slide plate 22 downwards, so that the positioning post 2211 exits from the slot 321, the limiting end 221 separates from the tail cylinder 32, and the sensor can resume free rotation to measure wind.

[0040] Reference Figures 2-3 as well as Figure 5 As an optional embodiment, the support portion 223 includes a hinge end 2231 that is hinged to the support block 23, and a groove surface 2232 that protrudes from the rear end of the support portion 223.

[0041] Furthermore, the support block 23 includes a connecting seat 231 that mates with the hinge end 2231, and a top block 232 hinged to the inside of the connecting seat 231. The connecting seat 231 includes an inner straight groove 2311 formed therein, and rows of holes 2312 linearly formed on both sides of the inner straight groove 2311.

[0042] In this embodiment, the support portion 223 is the interface at the bottom of the slide plate 22 for connecting to the support block 23. The hinge end 2231 is located at the lower front of the support portion 223, and its main body is a semi-cylindrical boss extending in the sliding direction of the slide plate 22. At the center axis of the semi-cylindrical boss, a transverse through pin hole is machined for installing the hinge pin.

[0043] Preferably, the groove surface 2232 protrudes from the rear end of the support portion 223, i.e., the side away from the hinge end opening, and can be a concave arc surface or a V-shaped inclined surface. The main function of this groove surface 2232 is to form a surface contact or line contact with the upper surface of the top block 232 at a specific angle, serving as a mechanical limit and load-bearing surface when the support block 23 rotates upward, preventing the support block 23 from folding upward excessively, and directly transferring part of the vertical load to the support portion 223.

[0044] Preferably, the support block 23 is a two-part hinged assembly, achieving connection with the support part 223 and adaptive fit at the bottom. Specifically, a rectangular inner straight groove 2311 with an opening at the top is formed on the end face of the connecting seat 231, parallel to the slide rail direction along its length. The straight groove 2311 is used to fold and accommodate the top block 232, forming a lateral insertion fit. Row holes 2312 are linearly formed on the side walls or front and rear walls of the inner straight groove 2311. The row holes 2312 are several through holes with intersecting outer diameters, used to position and install the hinge pin of the top block 232.

[0045] The upper end of the top block 232 is connected to the drain hole 2312 of the connecting seat 231 via a transverse hinge pin. By pulling the top block 232 laterally, it can be moved laterally along the drain hole 2312, thereby adjusting the position of the top block 232 within the inner straight groove 2311 and changing the relative angle between the support block 23 and the support part 223. When the top block 232 is at the outermost position of the inner straight groove 2311, it can be folded to be stored inside the inner straight groove 2311, facilitating the upward sliding of the slide plate 22. When the top block 232 moves to the relatively inner side of the inner straight groove 2311, the top block 232 is tilted and exposed outside the connecting seat 23. At this time, the support block 23 is in an outwardly flared and tilted state, facilitating the drain hole 2312 to the hinge position of the support block 23.

[0046] When the slide plate 22 is raised and slides along the slide rail 21, the support block 23 is suspended and hangs down naturally, while the top block 232 is fully embedded in the inner straight groove 2311. At this time, the support block 23 is completely closed under the slide plate 22 to prevent rotation between the limiting end 221 and the sensor tail cylinder 32.

[0047] As the slide plate 22 descends and the bottom of the support block 23 contacts the bottom surface of the base 31, the connecting seat 231 will adaptively rotate around the hinge point until its bottom is completely in contact with the surface of the base plate 31. Simultaneously, after the hinge axis of the top block 232 is adjusted to the appropriate position of the row of holes 2312, the top block 232 forms a stable support with the base surface; the top of the top block 232 contacts the groove surface 2232 of the support part 223. At this point, the contact between the groove surface 2232 and the top of the top block 232, together with the hinge axis, forms a stable force triangle, effectively transmitting the vertical support force and part of the horizontal force to the support part 223 and the entire bracket.

[0048] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.

[0049] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
