Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0037] Currently, air cooling with fans is one of the common heat dissipation methods for energy storage devices. To ensure the normal operation of the fans, regular maintenance is required. In energy storage devices with high energy density requirements, the operating space for fan maintenance is limited, and the disassembly and assembly process is relatively cumbersome, affecting maintenance efficiency.

[0038] In view of the above, embodiments of this application provide a wind turbine assembly to overcome at least one of the above-mentioned technical problems.

[0039] Reference Figure 1 , Figure 2 and Figure 3 The fan assembly includes a fixed component 1 and a movable component 2.

[0040] The fixed component 1 has a first ventilation opening 10, and the movable component 2 is equipped with a fan 3. The fan assembly has a first state and a second state. In the first state, at least a portion of the movable component 2 and the fan 3 are located inside the fixed component 1 so that the fan 3 can ventilate through the first ventilation opening 10. In the second state, at least a portion of the movable component 2 and the fan 3 are located outside the fixed component 1, and the movable component 2 is slidably connected to the fixed component 1 to switch between the first state and the second state.

[0041] It should be noted that this embodiment takes the application of a wind turbine component in energy storage device 8 as an example. Figure 1 and Figure 2 The portion of the energy storage device 8 for mounting the fixture 1 is introduced as an example. It is understood that in other embodiments, the wind turbine assembly may also be applied to other electrical equipment, which will not be elaborated here. In some embodiments, refer to... Figure 3 The fastener 1 has bolt holes 14 for bolting the energy storage device 8.

[0042] By arranging the fan 3 on the movable part 2, when the fan 3 needs maintenance, the fan 3 can be moved out of the energy storage device 8 by moving the movable part 2, which facilitates quick maintenance of the fan 3 and improves maintenance efficiency. After maintenance is completed, the movable part 2 can be pushed back into the energy storage device 8 to quickly fix the fan 3.

[0043] In some embodiments, refer to Figure 1 as well as Figures 3 to 5 The fixing member 1 forms a movable guide groove 11, and at least a portion of the movable member 2 is movably disposed in the movable guide groove 11. The fixing member 1 is mounted on the energy storage device 8 and forms an opening 12 on one side that communicates with the movable guide groove 11. The movable member 2 can be inserted into the movable guide groove 11 through the opening 12. In this embodiment, in the first state, the movable member 2 is completely pushed into the movable guide groove 11 and the opening 12 is sealed, so that the fan 3 is completely placed in the movable guide groove 11. In the second state, the movable member 2 can be moved until the fan 3 is completely removed from the movable guide groove 11 for maintenance.

[0044] In some embodiments, refer to Figure 2 and Figure 3 The movable component 2 has a second ventilation opening 20, and the fan 3 is installed in the second ventilation opening 20. In the second state, the second ventilation opening 20 is directly opposite the first ventilation opening 10. When using the fan 3 for ventilation, the direct alignment of the first ventilation opening 10 and the second ventilation opening 20 reduces obstruction to the ventilation path of the fan 3, thereby fully utilizing the ventilation effect of the fan 3. It should be noted that in this embodiment, two first ventilation openings 10 are provided as an example, and correspondingly, two second ventilation openings 20 and two fans 3 are also provided. In other embodiments, the number of first ventilation openings 10, second ventilation openings 20, and fans 3 can be flexibly increased or decreased as needed, which will not be elaborated here.

[0045] In some embodiments, refer to Figure 1 and Figure 3 To improve the stability of the fan assembly in its first state, ensuring stable ventilation between the first vent 10 and the second vent 20, the fan assembly also includes a locking assembly 4. The locking assembly 4 includes a limiting member 40 and a locking member 41. One of the limiting member 40 and the locking member 41 is located on the fixed member 1, and the other is located on the movable member 2. In the first state, the locking member 41 is configured to lock the limiting member 40. It is understood that the limiting member 40 and the locking member 41 can be flexibly adjusted in their installation positions according to design requirements, ensuring that the limiting member 40 and the locking member 41 can be locked or unlocked by an operator on the opening 12 side.

[0046] In some embodiments, refer to Figure 3 and Figure 6 In this embodiment, the locking member 41 is mounted on the movable member 2, and the fixed member 1 is mounted on the fixed member 1. The locking member 41 includes a mounting part 410 and a locking part 411. The mounting part 410 is fixed to the side of the movable member 2 opposite to the opening 12. The locking part 411 is movably connected to the mounting part 410. In a first state, the locking part 411 locks onto the limiting member 40. In a second state, the locking part 411 disengages from the limiting member 40. By mounting the adjustable locking part 411 on the movable member 2, it is easier for the operator to operate compared to mounting it on the fixed member 1.

[0047] In some embodiments, refer to Figure 5 and Figure 8 To further improve the stability of the locking member 40, the locking member 41 also includes an elastic part 412. The elastic part 412 is located on the mounting part 410. In a first state, the elastic part 412 abuts against the locking member 411 and restricts the locking member 411 from disengaging from the limiting member 40. In a second state, the locking member 411 pushes against the elastic part 412, causing the elastic part 412 to undergo elastic deformation. When it is necessary to disengage the locking member 411 from the limiting member 40, the locking member 411 must first be pushed against the elastic part 412 to overcome the elastic force and cause the elastic part 412 to undergo elastic deformation, thereby releasing the restriction of the locking member 411 by the elastic part 412.

[0048] In some embodiments, refer to Figure 3 , Figure 6 and Figure 8The mounting portion 410 has a receiving cavity 4100 and a limiting groove 4101 communicating with the receiving cavity 4100. An elastic portion 412 is disposed within the receiving cavity 4100. The limiting groove 4101 extends longitudinally through both opposite sides of the mounting portion 410, and its extension direction is parallel to the sliding direction of the movable portion along the moving guide groove 11. The locking portion 411 includes a rotating shaft 4110 and a push-pull handle 4111 connecting the rotating shaft 4110. The rotating shaft 4110 passes through the receiving cavity 4100 and the limiting groove 4101, with both ends of the rotating shaft 4110 extending to opposite sides of the mounting portion 410. The push-pull handle 4111 connects both ends of the rotating shaft 4110. The limiting member 40 has a locking groove 400 on the side opposite to the mounting portion 410 to form a barb structure. The rotating shaft 4110 is slidably disposed in the limiting groove 4101 and connected to the elastic part 412. The limiting groove 4101 is used to guide the rotating shaft 4110 to switch positions between a first state and a second state. In the first state, a portion of the push-pull handle 4111 is embedded in the locking groove 400, and the elastic part 412 abuts against the rotating shaft 4110. It should be noted that the push-pull handle 4111 can rotate toward the locking groove 400 by means of the rotating shaft 4110. During the compression of the elastic part 412, a portion of the push-pull handle 4111 can move to the side of the locking groove 400 away from the opening 12. At this time, when the push-pull handle 4111 is released, the elastic part 412 can push the portion of the push-pull handle 4111 into the locking groove 400 during the rebound process and keep it embedded in the locking groove 400, thereby improving the stability of the locking part 411 locking the limiting member 40.

[0049] It is understandable that, in some embodiments, the elastic deformation and extension of the elastic part 412 can be set such that when the elastic part 412 pushes a portion of the push-pull handle 4111 into the locking groove 400, the elastic part 412 can fully recover. At this time, there is no elastic force between the elastic part 412 and the rotating shaft 4110. The rotating shaft 4110 is pushed to compress the elastic part 412 only when the limiting effect of the elastic part 412 on the push-pull handle 4111 needs to be released. In addition, in other embodiments, it can also be preset that when the elastic part 412 pushes a portion of the push-pull handle 4111 into the locking groove 400, the elastic part 412 does not fully recover, that is, the elastic part 412 has a pre-pressure on the rotating shaft 4110, thereby further improving the stability of the push-pull handle 4111 embedded in the locking groove 400.

[0050] In some embodiments, refer to Figure 6The fan assembly also includes a positioning element 5. One of the fixed element 1 and the movable element 2 is provided with the positioning element 5, and the other has a positioning hole 21 for the positioning element 5 to pass through. In the first state, the positioning element 5 is inserted into the positioning hole 21. In this embodiment, the positioning element 5 is provided with the fixed element 1 as an example. Correspondingly, the movable element 2 is provided with a positioning hole 21 relative to the positioning element 5. During the process of the movable element 2 being fully pushed into the moving guide groove 11, the positioning element 5 can be inserted into the relative positioning hole 21, thereby further improving the accuracy and stability of the movable element 2 being embedded in the moving guide groove 11. In some embodiments, the positioning element 5 can be set as a cone and made of elastic material. As the positioning element 5 is inserted into the positioning hole 21, the stability of the positioning element 5 connecting to the positioning hole 21 can be increased, thereby helping to improve the stability of the movable element 2 in the moving guide groove 11.

[0051] In some embodiments, refer to Figure 5 The fixing member 1 has a drainage hole 130 at its bottom along its height. The fixing member 1 also has a bottom wall 13 along its height, on which the drainage hole 130 is located. The bottom wall 13 can have a preset slope towards the drainage hole 130, thereby improving the effect of guiding water flow towards the drainage hole 130 for discharge. Furthermore, in this embodiment, the bottom wall 13 can also be provided with a structure such as a wiring hole 131 for the wiring of the fan 3 to be led out through the movable guide groove 11. It is understood that during the operation of the fan 3, the fan 3 draws external air into the energy storage device 8 for air cooling. Some moisture in the external air will adhere to the fixing member 1 and the movable member 2. The drainage hole 130 allows the water droplets formed by the adhesion to be discharged in a timely manner, thereby reducing water accumulation in the movable guide groove 11 and improving the protection of the fixing member 1 and the movable member 2.

[0052] In some embodiments, refer to Figure 1 A ventilation hood 6 is installed on the fastener 1 at the first ventilation opening 10. The ventilation hood 6 helps to further filter impurities and moisture in the air, reduce the entry of impurities and moisture into the energy storage device 8, and improve the protection of the components inside the energy storage device 8.

[0053] In some embodiments, refer to Figure 3 A shock-absorbing pad 7 is attached to the side of the movable part 2 facing the fixed part 1, and the shock-absorbing pad 7 is attached to the fan 3. The shock-absorbing pad 7 can be made of elastic insulating material. By attaching it to the fan 3, it helps to reduce the vibration generated by the fan 3 during operation, avoids the fan 3 from directly and rigidly colliding with the movable part 2, and improves the protection of the movable part 2 and the fan 3.

[0054] In some embodiments, refer to Figure 2 , Figure 3 and Figure 7 The movable component 2 is equipped with a wiring maintenance window 22. It can be understood that this wiring maintenance window 22 is located at the wiring position of the fan 3. For example... Figure 2As shown, the energy storage device 8 also has a window and a pull-out plate 80 corresponding to the wiring maintenance window 22. When it is necessary to pull out the movable part 2 from the movable guide 11, the wiring of the fan 3 needs to be disconnected in advance. At this time, the pull-out plate 80 is pulled open from one side of the energy storage device 8, so that the operator can pass through the wiring maintenance window 22 to disconnect the wiring of the fan 3.

[0055] Accordingly, the energy storage device 8 provided in this application embodiment is used to store and release electrical energy. It is understood that the energy storage device 8 can have all the technical features and technical effects of the above-mentioned wind turbine components, which will not be repeated here.

[0056] The wind turbine assembly and energy storage device provided in the embodiments of this application have been described in detail above, and specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
