[0002] Large wind turbines typically refer to wind turbines with a power output of 5MW or more. They have large-sized rotors and high power output capabilities to meet large-scale power demands. To ensure the safety of workers at heights, large wind turbines usually have warning devices installed at the top of the unit or in key areas to remind workers to pay attention to safety.

[0003] The blades are the main components of a wind turbine that capture wind energy, and they are quite long. Warning devices installed on the surface of the tower can alert workers when they are about to enter the blade area, reminding them to pay attention to the rotation and swaying of the blades and avoid accidents.

[0004] However, when not in use, the surface of existing warning devices is still exposed to the outside environment. Prolonged exposure to sunlight may cause the plastic, rubber and other materials of the warning devices to age and become brittle due to ultraviolet radiation, leading to cracking or damage, which will affect the effectiveness and service life of the warning devices. Utility Model Content

[0005] To address the shortcomings of existing technologies, warning devices remain exposed to the external environment when not in use. Prolonged exposure to sunlight can cause the plastic and rubber materials of these devices to age and become brittle due to ultraviolet radiation, leading to cracking or damage and affecting the effectiveness and lifespan of the warning devices. This invention proposes a large wind turbine unit with a high-altitude warning device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a large wind turbine with a high-altitude warning device, including a base, a tower fixedly installed on the top of the base, a nacelle fixedly installed on the top of the tower, a hub movably installed on the left side of the nacelle, blades fixedly installed on the surface of the hub, and a storage mechanism installed on the surface of the tower.

[0007] The storage mechanism includes a fixed base, the inner side of which is fixedly connected to the surface of the tower. A storage base is installed on the top of the fixed base. A servo motor is fixedly connected to the back of the storage base. A worm gear is fixedly connected to the output end of the servo motor. A worm wheel is meshed with the bottom of the worm gear.

A positioning rod is fixedly connected to the right side of the moving plate. A warning light is fixedly installed on the right side of the positioning rod. A storage slot is opened in the inner cavity of the storage base. The inner cavity of the storage slot is movably connected to the surface of the warning light.

[0008] Preferably, a limiting groove is provided on both the front and back sides of the inner cavity of the storage slot, and a limiting plate is slidably connected to the inner cavity of the limiting groove. One side of the limiting plate is fixedly connected to the surface of the moving plate.

[0009] Preferably, a protective cover is mounted on the surface of the servo motor, and the front side of the protective cover is fixedly connected to the back side of the storage base.

[0010] Preferably, a connecting plate is installed on the surface of both the fixing base and the storage base, and a connecting rod is threaded into the inner cavity of the connecting plate. The surface of the connecting rod is threaded into the inner cavity of both the fixing base and the storage base.

[0011] Preferably, a support plate is fixedly connected to the right side of the storage base, a baffle is slidably connected to one side of the support plate, the bottom of the baffle is inclined, and the left side of the baffle is slidably connected to the right side of the storage base.

[0014] The advantages of this utility model are:

[0015] This invention features a storage mechanism that uses a servo motor to drive a worm gear, which in turn drives a worm wheel, which in turn drives a lead screw. The lead screw then moves a moving plate, which in turn moves a positioning rod, which in turn moves the warning light until it is stored inside the storage slot. This prevents the warning light from being exposed to the external environment for extended periods. It also solves the problem that when warning devices are not in use, their surfaces remain exposed to the external environment.

[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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a large wind turbine with a high-altitude warning device. (Refer to...) Figure 1 , Figure 2 and Figure 3 A large wind turbine with a high-altitude warning device includes a base 1, a tower 2 fixedly installed on the top of the base 1, a nacelle 5 fixedly installed on the top of the tower 2, a hub 4 movably installed on the left side of the nacelle 5, blades 3 fixedly installed on the surface of the hub 4, and a storage mechanism 6 installed on the surface of the tower 2.

[0025] The storage mechanism 6 includes a fixed base 601, the inner side of which is fixedly connected to the surface of the tower 2. A storage base 604 is installed on the top of the fixed base 601. A servo motor 605 is fixedly connected to the back side of the storage base 604. A worm gear 610 is fixedly connected to the output end of the servo motor 605. A worm wheel 609 is meshed with the bottom of the worm gear 610. A lead screw 611 is fixedly connected to the inner cavity of the worm wheel 609. A moving plate 615 is threadedly connected to the surface of the lead screw 611. A positioning rod 608 is fixedly connected to the right side of the moving plate 615. A warning light 607 is fixedly installed on the right side of the positioning rod 608. A storage groove 614 is opened in the inner cavity of the storage base 604. The inner cavity of the storage groove 614 is movably connected to the surface of the warning light 607.

[0026] Reference Figure 3 Limiting grooves 613 are provided on the front and back sides of the inner cavity of the storage slot 614. A limiting plate 612 is slidably connected to the inner cavity of the limiting groove 613. One side of the limiting plate 612 is fixedly connected to the surface of the moving plate 615. By setting the limiting groove 613, the limiting plate 612 can slide inside the storage slot 614. Thus, by setting the limiting plate 612, the movement of the moving plate 615 is limited, preventing the moving plate 615 from moving too far, causing the lead screw 611 to contact the warning light 607, which may affect the normal use of the warning light 607.

[0027] Reference Figure 2 and Figure 3 A protective cover 620 is installed on the surface of the servo motor 605. The front side of the protective cover 620 is fixedly connected to the back side of the storage base 604. The protective cover 620 protects the surface of the servo motor 605 and prevents the surface of the servo motor 605 from being exposed to the outside for a long time and being corroded.

[0028] Reference Figure 2 Both the fixed base 601 and the storage base 604 are equipped with connecting plates 603. The inner cavity of the connecting plate 603 is threaded with a connecting rod 606. The surface of the connecting rod 606 is threaded with the inner cavity of the fixed base 601 and the storage base 604 respectively. Through the setting of the connecting plate 603 and the connecting rod 606, the storage base 604 can be fixed to the top of the fixed base 601 to prevent the position of the storage base 604 from shifting during use.

[0029] Reference Figure 2 and Figure 4A support plate 618 is fixedly connected to the right side of the storage base 604. A baffle 602 is slidably connected to one side of the support plate 618. The bottom of the baffle 602 is inclined. The left side of the baffle 602 is slidably connected to the right side of the storage base 604. With the baffle 602 in place, when the bottom of the baffle 602 is not blocked, the baffle 602 will move downward under the action of gravity, which can seal the inside of the storage slot 614, further improving the protection effect of the warning light 607. At the same time, the support plate 618 is used to position the movement of the baffle 602 and prevent the baffle 602 from shifting position during movement.

[0030] Reference Figure 4 The inner cavity of the support plate 618 is provided with a movable groove 616, and a movable plate 619 is slidably connected to the inner cavity of the movable groove 616. One side of the movable plate 619 is fixedly connected to the surface of the baffle 602. By setting the movable groove 616, the movable plate 619 can slide inside the support plate 618, thereby limiting the movement of the baffle 602 and preventing the baffle 602 from moving too far, causing the baffle 602 to detach from the inner side of the support plate 618.

[0031] Reference Figure 4 A guide rod 617 is fixedly connected to the inner cavity of the movable groove 616. The surface of the guide rod 617 is slidably connected to the inner cavity of the movable plate 619. The guide rod 617 guides the movement of the movable plate 619, thereby improving the stability of the baffle 602 during movement and facilitating the vertical movement of the baffle 602.

[0032] Working principle: When the warning light 607 is not in use, to prevent its surface from being exposed to the external environment for extended periods, a servo motor 605 is started via an external power supply. The servo motor 605 drives the worm gear 610 to rotate, which in turn drives the worm wheel 609. The worm wheel 609 then drives the lead screw 611, which in turn moves the moving plate 615. The moving plate 615 then moves the positioning rod 608, which in turn moves the positioning rod 608. The movement of the light causes the warning light 607 to move. During this movement, the warning light 607 gradually retracts into the storage slot 614 until it is completely retracted. As the warning light 607 retracts into the storage slot 614, the baffle 602, without the obstruction of the warning light 607 at its bottom, gradually moves downwards under gravity. This movement of the baffle 602 causes the movable plate 619 to slide within the movable slot 616. The movable slot 616 is designed to... The baffle 602 is positioned to limit its movement, preventing it from moving too far and failing to stably seal the interior of the storage slot 614. Simultaneously, the guide rod 617 improves the stability of the baffle 602 during movement, facilitating its repositioning until it completely covers the interior of the storage slot 614. This protects the surface of the warning light 607 from prolonged exposure to the external environment, preventing damage to its effectiveness and lifespan. This ensures that the warning light can be used when needed in subsequent applications. When 607 is exposed to the external environment for warning purposes, the servo motor 605 drives the warning light 607 to move in reverse. During the movement of the warning light 607, the inclined surface at the top of the warning light 607 will contact the inclined surface at the bottom of the baffle 602. As the warning light 607 moves gradually, it pushes the baffle 602 upward. The movable groove 616 ensures the stopping position of the baffle 602, preventing the baffle 602 from being too low and causing its bottom inclined surface to fail to make normal contact with the warning light 607.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
