Description

Technical Field

[0001] This utility model relates to the field of obstruction light technology, and in particular to an aviation obstruction indicator device for wind turbine generator sets. Background Technology

[0002] Wind turbines are typically tens or even hundreds of meters tall, with blades of considerable diameter. At night or in low visibility conditions, they pose a potential threat to aircraft such as planes and helicopters flying at low altitudes. Installing aviation obstruction lights can effectively alert aircraft pilots to the presence of tall obstacles ahead, allowing them to adjust their flight paths in time and avoid collisions.

[0003] To ensure the lights have a wider field of vision and are not obstructed by the rotating blades, allowing aircraft to see them clearly from different angles, aviation obstruction lights are installed on the outer side of the nacelle, away from the blades. Therefore, in the past, when maintaining aviation obstruction lights on wind turbines, workers often had to stand directly outside the nacelle to operate them. The nacelle is located at a high altitude, and the surrounding environment is complex, with frequent occurrences of severe weather such as strong winds and low temperatures. This poses a great safety risk to maintenance personnel, and a slight mistake could lead to a fall. Moreover, the complex high-altitude working environment increases the difficulty of maintenance, prolongs maintenance time, and reduces maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an aviation obstacle indication device for wind turbine generator sets, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An aviation obstruction indicator device for a wind turbine generator set includes a base, with end plates fixedly installed at both ends of the base, guide plates fixedly installed on both sides inside the base, and a support plate movably installed between the two guide plates. A bottom plate is fixedly installed at the lower end of the support plate, and two metal cards are symmetrically fixedly installed at the center of one side of the bottom plate. A C-shaped bracket is fixedly installed on the support plate, and an obstruction light is fixedly installed on the C-shaped bracket. The obstruction light is electrically connected to a power source inside the wind turbine generator nacelle via a connecting wire.

[0007] As a further optimization of this utility model, a cable groove is provided at the bottom of the base. The cable groove allows the connecting cable of the obstruction light to extend into the wind turbine nacelle via the C-shaped bracket, the support plate, the cable groove, and one end of the cable.

[0008] As a further optimization of this utility model, a slot is provided in the end plate, and a protective shell is fixedly installed on one side of the end plate. The slot provides a limiting condition for the base plate to cooperate with the metal card to support the plate, and the protective shell can protect the metal card inserted into the slot.

[0009] As a further optimization of this utility model, two fixed shafts are fixedly installed on one side of one of the end plates, and one side of the two fixed shafts is inserted into a groove on the other side of the end plate. A compression spring is also fitted on the outside of the fixed shaft.

[0010] As a further optimization of this utility model, two Z-shaped sliding plates are fixedly installed at the lower end of the support plate. Multiple ball bearings are rotatably installed between the Z-shaped sliding plates and the guide plate. The support plate is slidably connected between the two guide plates through the two Z-shaped sliding plates. The support plate has a shaft hole corresponding to the direction of the fixed shaft, and the fixed shaft is inserted into the corresponding shaft hole.

[0011] As a further optimization of this utility model, the metal card is bent in the middle and has a card mounting part, and the end of the metal card away from the base plate is bent and has a bending part, and a connecting groove is formed in the bending part.

[0012] As a further optimization of this utility model, a first connecting rope is rotatably connected in the connecting groove, and a second connecting rope is fixedly connected to one end of the two first connecting ropes away from the bending part. One end of the second connecting rope passes through the bottom plate and the base and extends to one side of the protective shell via one of the end plates. A pull ring is fixedly installed at the end of the second connecting rope away from the first connecting rope. The setting of the two metal cards allows the force of the medium compression spring of the support plate to automatically move towards one of the end plates, and causes the two metal cards to be inserted into the slots in the corresponding end plates. Thus, the metal cards limit the bottom plate through the locking part, thereby limiting the position of the support plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the base is installed on the nacelle of a wind turbine, and the obstruction light is installed through a support plate and a C-shaped bracket. The two metal clips at the lower end of the support plate and the end plate at one end of the base limit the installation position of the obstruction light. The first and second connecting ropes can contact the limit of the support plate, and the obstruction light can be pulled towards the maintenance port of the wind turbine nacelle by pulling the support plate. This makes it convenient for personnel to maintain the obstruction light without having to stand outside the wind turbine nacelle, thus reducing maintenance risks. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, the present invention provides an aviation obstacle indication device for a wind turbine generator set, comprising a base 1, end plates 2 fixedly installed at both ends of the base 1, guide plates 3 fixedly installed on both sides of the base 1, and a support plate 4 movably installed between the two guide plates 3. A bottom plate 5 is fixedly installed at the lower end of the support plate 4 biased towards the end plate 2, and two metal cards 6 are symmetrically fixedly installed at the middle position of the bottom plate 5 biased towards the end plate 2. A C-shaped bracket 7 is fixedly installed on the support plate 4, and an obstacle light 8 is fixedly installed on the C-shaped bracket 7. The obstacle light 8 is electrically connected to the power supply inside the wind turbine generator nacelle via a connecting wire.

[0023] like Figure 2 As shown, a cable groove 9 is provided at the bottom of the base 1. The cable groove 9 allows the connecting cable of the obstruction light 8 to extend into the wind turbine nacelle via the C-shaped bracket 7, the support plate 4, the cable groove 9, and one end of the cable.

[0024] like Figures 1-5As shown, a slot 12 is provided in the end plate 2 corresponding to the position of the base plate 5. A protective shell 13 is fixedly installed on the outer side of the end plate 2. The slot 12 provides a limiting condition for the base plate 5 to cooperate with the metal card 6 to support the support plate 4. The protective shell 13 protects the metal card 6 inserted into the slot 12. Two fixing shafts 10 are fixedly installed on one side of one end plate 2, and one side of the two fixing shafts 10 is inserted into the groove on one side of the other end plate 2. A compression spring 11 is also fitted on the outside of the fixing shafts 10. Two Z-shaped sliding plates 14 are fixedly installed at the lower end of the support plate 4. Multiple balls 15 are rotatably installed between the Z-shaped sliding plates 14 and the guide plate 3. The support plate 4 is slidably connected between the two guide plates 3 through the two Z-shaped sliding plates 14. The support plate 4 has shaft holes corresponding to the direction of the fixing shafts 10, and the fixing shafts 10 are inserted into the corresponding shaft holes. The card 6 has a clamping part 16 bent in the middle. The end of the metal card 6 away from the base plate 5 has a bending part 17 bent. A connecting groove 18 is opened in the bending part 17. A first connecting rope 19 is rotatably connected in the connecting groove 18. A second connecting rope 20 is fixedly connected to the end of the two first connecting ropes 19 away from the bending part 17. One end of the second connecting rope 20 passes through the base plate 5 and the base 1 and extends to one side of the protective shell 13 via one of the end plates 2. A pull ring 21 is fixedly installed at the end of the second connecting rope 20 away from the first connecting rope 19. The arrangement of the two metal cards 6 allows the support plate 4 to move automatically towards one of the end plates 2 by means of the compression spring 11, and the two metal cards 6 are clamped into the corresponding slots 12 in the end plates 2. Thus, the metal cards 6 limit the position of the base plate 5 through the clamping part 16, thereby limiting the position of the support plate 4.

[0025] It should be noted that this utility model is an aviation obstacle indication device for wind turbine generator sets. During installation, the base 1 is first fixed to the nacelle of the wind turbine generator. Under normal operating conditions, under the action of the compression spring 11, the support plate 4 slides along the guide plate 3 towards the end plate 2 at one end via the ball bearings 15 in the lower Z-shaped sliding plate 14. At this time, the locking part 16 on the metal card 6 will lock into the slot 12 of the end plate 2, thereby limiting the support plate 4 and the obstacle light 8 installed on it, ensuring that the obstacle light 8 works stably and indicating the obstacle position for the aircraft.

[0026] When maintenance is required on the obstruction light 8, pull the pull ring 21 located on one side of the protective shell 13. The pull ring 21, in conjunction with the second connecting rope 20, drives the first connecting rope 19 connected to it. The two first connecting ropes 19 then pull the bent parts 17 at one end of the two metal cards 6 toward the base plate 5, so that the two metal cards 6 bend with the connection point with the base plate 5 as the fulcrum. This prevents the mounting parts 16 on the metal cards 6 from contacting the end plate 2 side. Then, the tension of the first connecting rope 19 and the second connecting rope 20 continues to pull the two metal cards 6, in conjunction with the base plate 5, toward the support plate 4. Thus, the support plate 4 slides along the guide plate 3, pulling the obstruction light 8 to the maintenance port of the wind turbine nacelle, making it convenient for the staff to perform maintenance operations.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
