Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower monitoring technology, specifically to an installation structure for a wind turbine tower monitoring system. Background Technology

[0002] The wind turbine tower is a key supporting structure of the wind turbine generator set. It mainly supports the nacelle, blades and adjusts the height, while also providing vibration damping to ensure stable operation of the unit. Abnormal vibrations caused by tower tilting may cause power output fluctuations and pose challenges to grid frequency regulation. Therefore, anti-tilt monitoring of the wind turbine tower is a core measure to ensure the safe operation of the wind farm.

[0003] For example, patent CN202421583466.4 discloses a wind turbine tower tilt monitoring device. It includes a support frame, bolts, a laser transmitter and receiver, a support plate, a reflector, a fixing mechanism, a frame, a rotating rod, an elliptical plate, two sliding plates, two springs, two insert plates, and a slider working together. The two ends of the springs are fixedly connected to their corresponding sliding plates. The rotating rod is rotatably connected to the frame, and the elliptical plate is fixedly connected to the rotating rod. Both elliptical plates are in contact with the two sliding plates. This method allows for easier installation and removal of the laser transmitter and receiver, improving work efficiency.

[0004] During installation, the aforementioned wind turbine tower tilt monitoring equipment is installed by mounting the laser transmitter and receiver in the middle of the lower end of the frame, while one end of the frame is fixed to the outer wall of the tower by means of a support rod and a wing plate with screw threads. Since the tower is exposed to the outside for a long time, the exposed screws are directly fixed to the outer wall of the tower, which is susceptible to corrosion from rainwater over a long period of time, thus affecting the stability of the overall monitoring equipment and the support installation.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0011] Furthermore, the shielding mechanism includes an arc-shaped bonding block and a T-shaped embedding groove formed in the middle of the lower end of the arc-shaped bonding block.

[0012] Furthermore, the lower end of the arc-shaped bonding block is provided with insertion grooves on both sides, and a sliding groove is provided in the middle of one side of the inner wall of the insertion groove.

[0013] Furthermore, the pre-fixed component includes an arc-shaped support rod and a semi-circular block fixedly installed at the lower end of the arc-shaped support rod, with corresponding magnetic stickers embedded in the inner wall of the semi-circular block.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1As shown, an installation structure for a wind turbine tower monitoring system includes a ground 1 and a wind turbine tower 2 fixedly installed on the upper part of the ground 1. A reflector 3 is installed on one side of the upper end of the ground 1. A monitoring component 4 is threadedly fixedly installed on one side of the outer wall of the wind turbine tower 2. The monitoring component 4 is configured to monitor the installation angle of the wind turbine tower. A protective component 5 is installed at the connection between the monitoring component 4 and the wind turbine tower 2 to limit the connection. The protective component 5 is configured to protect the connection between the monitoring component 4 and the wind turbine tower 2. A pre-fixing component 6 is fixedly installed on one side of the upper end of the monitoring component 4. The pre-fixing component 6 is configured to pre-fix the monitoring component 4 after the protective component 5 is removed.

[0026] When the laser transmitter and receiver 43 is working, it can emit a laser. The emitted laser is reflected by the reflector 3 and then re-received by the laser transmitter and receiver 43 to monitor the tilt of the wind turbine tower 2.

[0027] The power supply and principle of the laser transmitter and receiver 43 are clear to those skilled in the art and will not be described in detail here.

[0028] It should be noted that the specific model and specifications of the laser transmitter and receiver 43 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0029] like Figure 2 As shown, the protective component 5 includes a shielding mechanism 51 and a pull handle 52 fixedly installed in the middle of the upper end of the shielding mechanism 51. The pull handle 52 is configured to drive the shielding mechanism 51 to move up and down. A magnetic patch 53 is embedded in the middle of the upper end of the pull handle 52.

[0030] The monitoring component 4 includes a T-shaped bracket 41 and fixing screws 42 threadedly installed on both sides of one end of the T-shaped bracket 41. The fixing screws 42 pass through both ends of the T-shaped bracket 41 and the side wall of the wind turbine tower 2 for threaded fixation. The T-shaped bracket 41 corresponds to the support rod and wing plate mentioned in the background art, and is referred to as the T-shaped bracket 41.

[0031] The other end of the T-shaped bracket 41 is equipped with a laser emitter / receiver 43. The installation method and working principle of the laser emitter / receiver 43 and the T-shaped bracket 41 are the same as those of the frame, rotating rod, elliptical plate, sliding plate, spring, insert plate, slider, push-pull component, force-applying component, mounting wing plate, support rod, groove, slide and slot in publication number CN202421583466.4, and will not be described again here.

[0032] A support mechanism 44 is fixedly installed on one side of the lower end of the T-shaped bracket 41. The support mechanism 44 is configured to support the installation, movement and adjustment of the guide and protective assembly 5.

[0033] like Figure 3 As shown, the support mechanism 44 includes a fixed base plate 441 and an insertion plate 442 fixedly installed on both sides of the upper end of the fixed base plate 441. A threaded rod 443 is fixedly installed on the middle of the upper end of one side of the outer wall of the insertion plate 442, and a positioning nut 444 is threadedly connected to the outer surface of the threaded rod 443.

[0034] like Figure 4 As shown, the shielding mechanism 51 includes an arc-shaped fitting block 511 and a T-shaped embedding groove 512 opened in the middle of the lower end of the arc-shaped fitting block 511. The T-shaped bracket 41 is movably installed in the inner cavity of the T-shaped embedding groove 512, and the screws threaded on both sides of one end of the T-shaped bracket 41 are wrapped in the T-shaped embedding groove 512.

[0035] The lower end of the arc-shaped fitting block 511 is provided with insertion slots 513 on both sides. The insertion plate 442 is movably installed in the inner cavity of the insertion slot 513. A sliding groove 514 is provided in the middle of one side of the inner wall of the insertion slot 513. The threaded rod 443 is movably installed in the inner cavity of the sliding groove 514 and is fixed by the positioning nut 444 threadedly pressing it on one side of the groove opening of the sliding groove 514.

[0036] In this application, when the T-shaped bracket 41 is fixedly installed on the side wall of the wind turbine tower 2 with screws, the fixing base plate 441 fixedly installed at the lower end of the T-shaped bracket 41 will also be fixedly installed. Since the upper end of the T-shaped bracket 41 is slidably limited by the arc-shaped fitting block 511, and the insertion plates 442 on both sides of the upper end of the fixing base plate 441 are slidably installed in the inner cavity of the insertion groove 513, when the operator installs the screws to fix the T-shaped bracket 41, the arc-shaped fitting block 511 can be moved to the upper end of the T-shaped bracket 41 first, so that the pre-fixed assembly... Part 6 limits and fixes the pull handle 52. After the screw is installed, pull down the arc-shaped adhesive block 511 so that it covers the upper end of the fixed base plate 441. The arc-shaped adhesive block 511 protects the installed screw, reduces the impact of rainwater on the screw, and improves the stability of the screw installation. At the same time, by rotating the positioning nut 444, the positioning nut 444 presses the threaded rod 443 into the inner cavity of the sliding groove 514 and fixes it, thereby completing the fixation of the position of the arc-shaped adhesive block 511.

[0037] like Figure 3 As shown, the pre-fixed component 6 includes an arc-shaped support rod 61 and a semi-circular block 62 fixedly installed at the lower end of the arc-shaped support rod 61. The upper end of the pull handle 52 is fitted into the inner cavity of the semi-circular block 62. A corresponding magnet 63 is embedded in the inner wall of the semi-circular block 62. The corresponding magnet 63 and the magnetic patch 53 are magnetically connected to complete the magnetic adsorption and fixation of the pull handle 52.

[0038] In this application, when the pull handle 52 is limited and fixed by the pre-fixing component 6, the pull handle 52 is moved to the lower end of the semi-circular block 62, so that the magnetic patch 53 at the upper end of the pull handle 52 is magnetically attracted to the upper end of the corresponding magnetic patch 63, thereby achieving magnetic attraction and completing the magnetic fixation of the pull handle 52, so that the setting position of the arc-shaped adhesive block 511 fixedly installed at the lower end of the pull handle 52 is limited and fixed.

[0039] In summary: the T-shaped bracket 41, wind turbine tower 2, fixed base plate 441, arc-shaped adhesive block 511, insertion plate 442, insertion slot 513, and threaded rod 443 work together to protect the installed screws and reduce the impact of rainwater on them. The pre-fixed component 6, arc-shaped support rod 61, semi-circular block 62, corresponding magnetic sticker 63, and magnetic patch 53 work together to magnetically fix the pull handle 52, thus limiting and fixing the position of the arc-shaped adhesive block 511 fixedly installed at the lower end of the pull handle 52.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
