[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0039] The following is combined with Figure 1-8 The invention describes an adjustable bracket for a through-beam wind speed sensor according to an embodiment of the invention.
[0040] like Figures 1 to 3 As shown, the adjustable bracket of the through-beam wind speed sensor according to the embodiment of the present invention includes a base 1 , a first bracket 2 , a fixing component 3 , a second bracket 4 and an adjusting component 5 .
[0041] The base 1 is suitable for installation on the inner wall of the tunnel. The first bracket 2 includes a mounting base 21 and a connecting rod 22. The mounting base 21 is detachably connected to the base 1. The first end of the connecting rod 22 (such as Figure 1The left end shown in FIG2 is connected to the mounting base 21, and the fixing assembly 3 is connected to the second end of the connecting rod 22 (as shown in FIG2 ). Figure 1 The second bracket 4 is detachably connected to the fixing assembly 3 and is rotatable with the axis of the fixing assembly 3 as the rotation center. The adjustment assembly 5 includes an adjustment shaft 51 and a first locking nut 52. The adjustment shaft 51 is rotatably connected to the second bracket 4. The adjustment shaft 51 is used to install the sensor. The first locking nut 52 is threadedly connected to the adjustment shaft 51 and is close to the first end of the adjustment shaft 51 (as shown). Figure 2 backend shown).
[0042] Optionally, the base 1 is designed as a structure suitable for installation on the inner wall of the tunnel and can be firmly fixed to the tunnel wall by bolts, welding or other fixing methods. The shape and size of the base 1 can be designed according to the specific conditions of the inner wall of the tunnel to ensure its stability and convenience of installation.
[0043] Optionally, the mounting base 21 is designed to be detachably connected to the base 1, for example, by bolts, snaps, etc., to facilitate disassembly and reinstallation during installation and maintenance. The first end of the connecting rod 22 is connected to the mounting base 21, which can be achieved by welding, bolt connection or other fixing methods.
[0044] Optionally, the fixing component 3 can be connected to the second end of the connecting rod 22 by welding, bolting or other fixing methods. The axis of the fixing component 3 serves as the rotation center of the second bracket 4, and its axis should be ensured to be stable without offset or deflection. When the angle of the second bracket 4 is adjusted, the fixing component 3 can lock the second bracket 4 on the fixing component 3 to avoid the second bracket 4 from deflecting under external influences and affecting the function of the sensor.
[0045] Optionally, the adjustment shaft 51 is connected to the second bracket 4 and is rotatable on the second bracket 4 about the axis of the adjustment shaft 51. The sensor can be connected to the adjustment shaft 51 by bolts, snaps, or other fixing methods. The first locking nut 52 is threadedly connected to the adjustment shaft 51 and is located near the first end of the adjustment shaft 51. The first locking nut 52 is used to lock the position of the adjustment shaft 51 to prevent it from accidentally rotating during operation. When the sensor angle needs to be adjusted, the first locking nut 52 can be loosened, the adjustment shaft 51 can be rotated to adjust the sensor angle, and then the first locking nut 52 can be tightened again to lock the position.
[0046] During installation, first secure base 1 to the tunnel's inner wall and mount the sensor on adjustment shaft 51. Then, connect second bracket 4 to fixing assembly 3, and attach mounting base 21 of first bracket 2 to base 1. Adjust the sensor's angle as needed by rotating second bracket 4 and / or adjusting shaft 51, enabling quick installation and adjustment. Base 1 can remain permanently attached to the tunnel's inner wall, saving materials and installation time. To replace or repair the sensor, remove mounting base 21 from base 1 or second bracket 4 from fixing assembly 3 to separate the sensor from base 1, enabling quick disassembly.
[0047] The adjustable bracket of the through-beam wind speed sensor in the embodiment of the utility model can quickly complete the installation of the sensor through the fixing component 3, the second bracket 4 and the adjustment component 5, effectively shortening the installation time of the sensor, and the installation angle and position of the sensor can be conveniently adjusted through the first bracket 2, the second bracket 4 and the adjustment component 5, effectively shortening the sensor angle positioning time, facilitating regular maintenance of the sensor, and ensuring stable operation of the sensor.
[0048] like Figures 1 to 4 As shown, in some embodiments, the fixing assembly 3 includes a sleeve 31 , a screw 32 , a limiting ring 33 , a clamping plate 34 and a second locking nut 35 .
[0049] The sleeve 31 is connected to the second end of the connecting rod 22 (such as Figure 1 The right end shown in FIG), and the axial direction of the sleeve 31 is perpendicular to the axial direction of the adjusting shaft 51, the screw 32 is connected to the sleeve 31 and along the axial direction of the sleeve 31 (as shown in FIG). Figure 4 The limit ring 33 is sleeved on the screw rod 32, and a sliding groove 311 is provided in the sleeve 31 for limiting the sliding range of the limit ring 33. The limit ring 33 is located in the sliding groove 311, and the splint 34 is connected to the first end of the screw rod 32. The splint 34 is located outside the sleeve 31 and close to the first end of the sleeve 31. At least a part of the second bracket 4 is located between the splint 34 and the sleeve 31, and is respectively abutted against the splint 34 and the sleeve 31. The second locking nut 35 is threadedly connected to the screw rod 32 and close to the second end of the screw rod 32. The second locking nut 35 is located outside the sleeve 31 and abuts against the second end of the sleeve 31.
[0050] Specifically, the axis of sleeve 31 is arranged vertically, and the axis of adjustment shaft 51 is arranged horizontally, so that the axis of sleeve 31 is perpendicular to the axis of adjustment shaft 51, thereby facilitating adjustment of the sensor angle. The design of limit ring 33 and slide groove 311 ensures that limit ring 33 can slide stably within slide groove 311 to limit the range of movement of screw 32.
[0051] It should be noted that the fixing assembly 3 is a key part connecting the first bracket 2 and the second bracket 4, and its stability and adjustability are crucial to the performance of the entire bracket; when disassembling the second bracket 4, loosen the second locking nut 35 and move the screw 32 to increase the distance between the clamping plate 34 and the sleeve 31. At this time, the clamping plate 34 and the sleeve 31 do not restrict the second bracket 4, and the second bracket 4 can be easily removed from the fixing assembly 3 to achieve rapid disassembly of the second bracket 4. When installing the second bracket 4, place a part of the second bracket 4 between the clamping plate 34 and the sleeve 31, tighten the second locking nut 35 to make the clamping plate 34 and the sleeve 31 decreases. When the splint 34 and the sleeve 31 are in contact with the second bracket 4, move or rotate the second bracket 4 to adjust the sensor to a suitable position or angle. At this time, since the splint 34 and the sleeve 31 are in contact with the second bracket 4, there is friction between the second bracket 4 and the splint 34 and the sleeve 31 to reduce the risk of relative movement between the second bracket 4 and the fixing component 3. Then tighten the second locking nut 35 to complete the quick installation of the second bracket 4; if it is necessary to adjust the position or angle of the second bracket 4, loosen the second locking nut 35, adjust the position and angle of the second bracket 4, and then tighten the second locking nut 35 again to lock the position.
[0052] Therefore, the fixing assembly 3 is arranged through the above structure, which not only improves the stability and reliability of the entire bracket, but also facilitates the adjustment of the angle of the sensor and the disassembly and assembly of the second bracket 4 on the fixing assembly 3.
[0053] like Figure 4 As shown, further, the fixing assembly 3 further includes a first elastic member 36, the first elastic member 36 is located in the slide groove 311 and between the limiting ring 33 and the nut, and the first end of the first elastic member 36 (as shown in FIG. Figure 4 The upper end shown in FIG) is against the limiting ring 33, and the second end of the first elastic member 36 (as shown Figure 4 The lower end shown in FIG30 abuts against the sleeve 31 so that the first elastic member 36 applies a thrust to the limiting ring 33 toward the first end of the sleeve 31.
[0054] Optionally, the material of the first elastic member 36 should have good elasticity and durability to ensure that stable thrust can be maintained during long-term use, such as metal, rubber, etc.; the shape of the first elastic member 36 can be set to different shapes according to actual conditions, such as spiral shape, wave shape, etc.
[0055] It should be noted that when the second locking nut 35 is loosened, the first elastic member 36 pushes the limit ring 33 upward under the action of its own elastic force, and the limit ring 33 drives the clamping plate 34 to rise through the screw 32 to facilitate the installation and disassembly of the second bracket 4; when the second locking nut 35 is tightened, the first elastic member 36 pushes the limit ring 33 upward under the action of its own elastic force, and the limit ring 33 drives the second locking nut 35 to move upward through the screw 32 and always squeezes and contacts with the lower end of the sleeve 31, thereby giving the second locking nut 35 a certain pre-tightening force and reducing the risk of the second locking nut 35 loosening due to external interference.
[0056] like Figures 1 to 4 As shown, in some embodiments, the second bracket 4 includes a flat plate 41 and two vertical plates 42, a portion of the flat plate 41 abuts between the clamping plate 34 and the sleeve 31, and the two vertical plates 42 are both connected to the flat plate 41 and are spaced apart along the axial direction of the adjusting shaft 51, and the adjusting shaft 51 passes through the two vertical plates 42 respectively.
[0057] Specifically, the flat plate 41 serves as the main supporting structure, a portion of which abuts between the clamping plate 34 and the sleeve 31, thereby realizing connection with the base 1 through the fixing component 3 and the first bracket 2; the two vertical plates 42 are both connected to the flat plate 41 and are located above the flat plate 41, and the two vertical plates 42 are respectively located at the front and rear ends of the flat plate 41, and the length directions of the two vertical plates 42 are both set along the left and right directions. The two vertical plates 42 are used to install the adjustment shaft 51, and a portion of the adjustment shaft 51 and a portion of the sensor are both located between the two vertical plates 42.
[0058] Optionally, a recess (not shown) matching the screw rod 32 is provided on the flat plate 41 to facilitate assembly and disassembly of the second bracket 4 .
[0059] It can be understood that the second bracket 4 simplifies the structure of the second bracket 4 and enhances the versatility of the second bracket 4 through the flat plate 41 and the two vertical plates 42 .
[0060] like Figure 5 As shown, in some embodiments, the adjustment assembly 5 further includes a positioning member 53, which is connected to the adjustment shaft 51 and is close to the second end of the adjustment shaft 51 (such as Figure 5 The front end is shown in the figure), a countersunk hole (not shown) matching the positioning member 53 is provided on the second bracket 4, and the adjusting shaft 51 is movable on the second bracket 4 so that the positioning member 53 has a locked position and an unlocked position. In the locked position, the positioning member 53 is located in the countersunk hole, thereby limiting the rotation of the adjusting shaft 51. In the unlocked position, the positioning member 53 is located outside the countersunk hole, thereby releasing the restriction on the adjusting shaft 51.
[0061] Optionally, the positioning member 53 has a gear-shaped appearance and is sleeved on the adjusting shaft 51 , and the inner contour of the countersunk hole matches the gear-shaped appearance of the positioning member 53 .
[0062] Optionally, the positioning member 53 has a regular polygonal shape and is sleeved on the adjusting shaft 51 , and the inner contour of the countersunk hole matches the gear-shaped shape of the positioning member 53 .
[0063] It should be noted that when the sensor needs to adjust the angle, move the adjusting shaft 51 to move the positioning member 53 to the unlocked position, then loosen the first locking nut 52, rotate the sensor to a suitable angle, and move the adjusting shaft 51 to move the positioning member 53 to the locked position. Since the positioning member 53 and the countersunk hole limit the rotation of the adjusting shaft 51, the rotation of the adjusting shaft 51 is avoided during the tightening of the first locking nut 52 to avoid deflection of the sensor. No additional tools or equipment are required, the adjustment process is convenient and quick, effectively shortening the sensor angle positioning time, and ensuring the stability and accuracy of the sensor during installation and use.
[0064] like Figures 6 to 8 As shown, in some embodiments, a receiving groove 11 is provided on the base 1, and the first bracket 2 is movable on the base 1 so that the first bracket 2 has an installation position and a disassembly position. In the installation position, at least a portion of the mounting seat 21 and at least a portion of the connecting rod 22 are both located in the receiving groove 11, and in the disassembly position, the mounting seat 21 and the connecting rod 22 are located outside the receiving groove 11.
[0065] Specifically, the accommodating groove 11 includes a first groove for accommodating and restricting the mounting seat 21 and a second groove for making way for and restricting the connecting rod 22. The opening of the first groove faces forward, and the width of the first groove is not less than the diameter of the mounting seat 21. The second groove is connected to the first groove, and the opening of the second groove faces forward. The upper end of the second groove passes through the upper end of the base 1, and the lower end of the second groove is at a certain distance from the lower end of the base 1. In the installation position, the mounting seat 21 is located in the first groove and is restricted by the first groove, and a part of the connecting rod 22 is located in the second groove and is restricted by the second groove.
[0066] It should be noted that, when the first bracket 2 is moved from the disassembly position to the installation position, the base 1 restricts the mounting seat 21 and the connecting rod 22 through the accommodating groove 11, and the first bracket 2 is installed on the base 1. When the first bracket 2 is moved from the installation position to the disassembly position, the first bracket 2 is separated from the base 1, and the first bracket 2 is disassembled from the base 1, thereby facilitating the installation of the sensor or disassembling the first bracket 2 from the base 1 for maintenance or replacement.
[0067] like Figure 7As shown, in some embodiments, the adjustable bracket of the through-beam wind speed sensor also includes a limit plate 6 and a second elastic member 7, and the limit plate 6 and the second elastic member 7 are both located in the accommodating groove 11, and the two ends of the second elastic member 7 are respectively against the base 1 and the limit plate 6. In the installation position, the mounting seat 21 is respectively against the base 1 and the mounting seat 21, and the mounting seat 21, the limit plate 6 and the second elastic member 7 are arranged sequentially along the axial direction of the connecting rod 22.
[0068] Optionally, the material of the second elastic member 7 should have good elasticity and durability to ensure that a stable thrust can be maintained during long-term use, such as metal, rubber, etc.; the shape of the second elastic member 7 can be set to different shapes according to actual conditions, such as spiral shape, wave shape, etc.
[0069] Specifically, the limiting plate 6 is located on the left side of the second elastic member 7 , the left end of the second elastic member 7 abuts against the limiting plate 6 , and the right end of the second elastic member 7 abuts against the base 1 , so that the second elastic member 7 applies a leftward thrust to the limiting plate 6 .
[0070] When the mounting seat 21 moves into the accommodating groove 11, the mounting seat 21 pushes the limiting plate 6 to move to the left to compress the second elastic member 7. Under the action of the elastic force, the second elastic member 7 applies a leftward thrust to the limiting plate 6 so that the limiting plate 6 squeezes the mounting seat 21 between the base 1 and the limiting plate 6, thereby restricting the mounting seat 21 to limit the movement of the first bracket 2.
[0071] like Figure 7 and Figure 8 As shown, in some embodiments, a plurality of limiting members 61 are provided on the limiting plate 6 , and a plurality of 211 corresponding to the plurality of limiting members 61 are provided on the mounting seat 21 , and the inner contour of 211 matches the outer shape of the limiting member 61 .
[0072] Optionally, the limiting member 61 has an outer shape of a cylinder, a regular polygon, a cone or other shapes, and the inner contour of 211 matches the outer shape of the limiting member 61 .
[0073] It is understandable that the plurality of limiting members 61 restrict the mounting base 21 to prevent the mounting base 21 from rotating around the axis of the connecting rod 22 and causing the sensor to deviate from the set position and angle.
[0074] In some embodiments, the connecting rod 22 is a telescopic rod. The telescopic range of the telescopic rod should be reasonably designed according to the alley to ensure that the bracket can be stably installed in different alleys. The telescopic rod should be designed with a locking mechanism, such as a locking screw, a buckle, etc., which is used to lock the position of the telescopic rod after it is extended to the required length to prevent it from accidentally extending and retracting during use.
