Technical Field
[0001] This utility model belongs to the field of early warning technology for wind turbine equipment, and specifically relates to a fault early warning device for new energy wind turbine equipment. Background Technology
[0002] With the increasing global emphasis on renewable energy utilization, wind energy, as a clean and renewable energy form, has seen rapid development and application. New energy wind turbines, as key devices for wind energy conversion, play an increasingly important role in the power supply system. To improve the operational reliability and maintenance efficiency of wind turbines, fault warning technology has emerged. Currently, various fault warning devices for new energy wind turbines are available on the market. One common design involves installing the warning device below the blades and shaft of the wind turbine, such as the "Fault Warning Device for Wind Power Stations, comprising Installation Components and Protection Components" disclosed in existing patent CN217950591U. The device includes a protective box, and the protective components include an electric cylinder, a support plate, an early warning instrument, an infrared speed sensor, a through slot, a cover plate, a mounting slot, a transparent plate, a screw, a motor, a driving bevel gear, a driven bevel gear, a nut seat, a connecting rod, a guide rod, and a controller. It can be seen that the device described in this application is a common fault early warning device for wind power stations. It mainly uses infrared speed sensors to monitor the rotational speed of the blades and the shaft in real time. By comparing whether the rotational speed of the blades and the rotational speed of the shaft are consistent, it can determine whether the wind turbine is in normal operation. Once a mismatch between the rotational speed of the blades and the shaft is found, it is regarded as a possible fault signal, and an early warning mechanism is triggered to notify the operation and maintenance personnel to take timely measures for maintenance.
[0003] However, the existing fault warning devices for wind power stations are often fixed in horizontal position during actual use and cannot be adjusted according to the actual installation environment or usage requirements. This fixed design not only limits the adaptability of the warning device to different wind turbine models or installation conditions, but may also affect its monitoring accuracy and warning effect due to the limitations of the installation position. Therefore, this utility model proposes a fault warning device for new energy wind turbine equipment. Utility Model Content

[0022] 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.
[0023] Example 1
[0024] Please see Figures 1 to 4 This is the first embodiment of the present utility model, which provides a technical solution: a fault early warning device for new energy wind turbine equipment, including...
[0025] The system comprises: a side base plate 1; a support plate 2 welded and fixed to the side of the side base plate 1; a warning device body 4 mounted on top of the support plate 2; two infrared speed sensors 5 mounted on top of the warning device body 4; and a base plate 3 fixed to the bottom surface of the warning device body 4. In actual use, the side base plate 1 needs to be bolted to the outer tower base of the wind turbine, allowing the two infrared speed sensors 5 to be positioned facing the wind turbine blades and shaft respectively, thereby monitoring the rotational speeds of the blades and shaft. When the two speeds are inconsistent, a fault is detected, and a warning is issued. The sound and light alarm light on the back of the main body 4 of the warning device is lit, and the above-mentioned structural principles are all technologies that have been disclosed in the prior art. For details, please refer to the existing patent with publication number CN217950591U. It will not be elaborated here. The base plate 3 is slidably installed on the top of the support plate 2. The bottom slider 31 is welded and fixed on the bottom surface of the base plate 3, and the surface of the support plate 2 is provided with a strip-shaped notch 21 corresponding to the bottom slider 31. A strip-shaped support plate 22 is horizontally welded and fixed in the strip-shaped notch 21, and the bottom slider 31 is slidably sleeved on the surface of the strip-shaped support plate 22.
[0026] An adjustment structure 6 is provided between the bottom slider 31 and the strip support plate 22. The adjustment structure 6 includes a U-shaped movable seat 61 movably installed on the bottom surface of the bottom slider 31, a movable locking rod 62 welded and fixed to the top surface of the U-shaped movable seat 61, and multiple limiting locking holes 63 opened on the surface of the strip support plate 22. The movable locking rod 62 passes through the inside of the bottom slider 31 and is inserted into one of the limiting locking holes 63, which can realize the stable limiting of the bottom slider 31 and the warning instrument body 4 during daily use. When it is necessary to adjust the installation position of the warning instrument body 4 horizontally, simply pull down the U-shaped movable seat 61 so that the top of the movable locking rod 62 moves out of the limiting locking hole 63, which can quickly release the limiting of the bottom slider 31 and the base plate 3. Then, the base plate 3 can be slid horizontally on the top of the support plate 2 to adjust the installation position of the warning instrument body 4, which improves the installation flexibility and versatility, so as to adapt to different models and specifications of wind turbine units.
[0027] In this embodiment, preferably, the adjustment structure 6 further includes two side sliding grooves 64 formed inside the bottom slider 31, a side slider 65 and a spring 66 installed in the side sliding grooves 64, and a side connecting rod 67 welded and fixed to the bottom surface of the side slider 65. The side slider 65 slides in the side sliding grooves 64, and the bottom end of the side connecting rod 67 extends to the bottom of the bottom slider 31 and is fixed to the U-shaped movable seat 61. Under the pushing action of the spring 66, the U-shaped movable seat 61 can stably fit against the bottom surface of the bottom slider 31 during daily use, ensuring the movable seat 61 can move freely. The top of the movable locking rod 62 can be stably inserted into one of the limiting locking holes 63 to ensure the limiting stability of the bottom slider 31 and the warning device body 4. When it is necessary to adjust the horizontal position of the warning device body 4 later, simply pull down the U-shaped movable seat 61 to make the side connecting rod 67 move down with the side slider 65 and compress the spring 66. This will smoothly pull the top of the movable locking rod 62 out of the limiting locking hole 63, quickly release the limiting of the bottom slider 31 and the base plate 3, and facilitate the sliding adjustment of the horizontal position of the warning device body 4.
[0028] In this embodiment, preferably, the spring 66 is located at the bottom of the side slider 65, and the side connecting rod 67 passes through the spring 66.
[0029] In this embodiment, preferably, the bottom surface of the bottom slider 31 has two rod holes corresponding to the side connecting rod 67, and the rod holes are connected to the side sliding groove 64 to allow the side connecting rod 67 to pass through smoothly.
[0030] In this embodiment, preferably, the top end of the spring 66 abuts against the bottom surface of the side slider 65, and the bottom end of the spring 66 abuts against the inner wall of the bottom end of the side slide groove 64.
[0031] Example 2
[0032] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the anti-detachment seat 23 can play an anti-detachment role during the sliding adjustment of the bottom slider 31.
[0033] Specifically, the left end of the strip notch 21 is connected to the left side surface of the support plate 2, allowing the subsequent bottom slider 31 to slide out from the left end of the strip support plate 22, thus separating the bottom plate 3 from the support plate 2. The left end surface of the strip support plate 22 is also equipped with an anti-detachment seat 23, which can prevent the bottom slider 31 from falling directly from the left end of the strip support plate 22 during the horizontal sliding adjustment of the main body 4 of the warning device, thus playing an anti-detachment role.
[0034] In this embodiment, preferably, a threaded block 231 is welded and fixed to the right side surface of the anti-detachment seat 23, and a threaded groove 221 matching the threaded block 231 is opened on the left end surface of the strip support plate 22. The threaded block 231 is screwed into the threaded groove 221 to achieve stable installation of the anti-detachment seat 23. When it is necessary to slide the bottom slider 31 out of the strip notch 21 to separate the bottom plate 3 from the support plate 2, the anti-detachment seat 23 can be easily removed by simply rotating the anti-detachment seat 23 counterclockwise to screw the threaded block 231 out of the threaded groove 221.
[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
