Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wind turbine guard installation technology, specifically relating to a wind turbine guard fixing structure that is easy to install. Background Technology
[0002] In the actual operation and deployment of wind turbine systems, to prevent personnel's hands or other foreign objects from entering the wind turbine and colliding with the high-speed rotating blades, thus causing safety accidents, it is usually necessary to install screens at the wind turbine's inlet and outlet. Traditional screen installation methods mainly rely on manual support for positioning, followed by tightening with screws, nuts, and other connectors. However, this installation method has revealed many drawbacks in actual operation:
[0003] 1. Poor positioning stability: The mesh cover lacks an effective pre-positioning mechanism during installation. Relying solely on manual support makes it difficult to maintain a stable installation posture, which can easily lead to detachment. This not only increases the difficulty of installation but may also cause injury to installers.
[0004] 2. High labor costs: The installation of the front and rear guards of the wind turbine usually requires two people to work together, one to fix the guard and the other to tighten the screws. This undoubtedly increases labor and time costs significantly and reduces the overall installation efficiency.
[0005] 3. Significant safety hazards: During installation, the mesh cover is difficult to position accurately, leading to difficulties in aligning screw holes and a prolonged installation time. Furthermore, due to factors such as vibration and temperature differences, the screws are prone to loosening, causing the mesh cover to detach and seriously threatening the safe and stable operation of the wind turbine. Utility Model Content
[0006] To address the above problems, the purpose of this utility model is to provide an easy-to-install fan guard fixing structure, solving the problems of cumbersome and inefficient installation and disassembly of existing fan guards, as well as unstable fixing.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a fan cover fixing structure that is easy to install, comprising a fan frame and a fan cover, wherein the front and back end faces of the fan frame are provided with grooves adapted to fit the end of the fan cover, the inner wall of the groove is formed with protrusions, and the end of the fan cover is snapped between the protrusions and the groove.
[0008] The beneficial effects of this utility model are as follows: by designing grooves and protrusions on the fan frame, the mesh cover can be quickly fixed without manual support or fixtures, thereby simplifying the installation process, reducing labor costs, and improving installation efficiency.
[0009] In order to initially position the mesh cover on the fan frame during installation;
[0010] As a further improvement to the above technical solution: the inner wall of the groove is adapted to fit the end of the connecting rod of the mesh cover.
[0011] The beneficial effects of this improvement are: the groove is formed according to the specific shape of the end of the mesh cover to limit the mesh cover, prevent the mesh cover from shifting relative to the fan frame, and ensure the stability of the connection between the mesh cover and the fan frame.
[0012] For easy removal of the mesh cover;
[0013] As a further improvement to the above technical solution: the end face of the protrusion facing the fan frame is an arc-shaped surface structure.
[0014] The beneficial effects of this improvement are: the end of the mesh cover, which can be made of different elastic materials, can slide along the bottom surface of the protrusion, and after being squeezed and deformed, it will produce elastic deformation and separate from the fan frame.
[0015] In order to allow the mesh cover to effectively deform elastically for installation or removal;
[0016] As a further improvement to the above technical solution: the connecting rod of the mesh cover is bent and tilted in the axial direction of the inner and outer rings of the mesh cover.
[0017] The beneficial effect of this improvement is that the elastic connecting rod of the raised mesh cover can more easily generate elastic deformation when the end is engaged between the protrusion and the fan frame, thereby improving the ease of mesh cover installation.
[0018] To avoid structural interference between the connecting rod of the mesh cover and the fan frame;
[0019] As a further improvement to the above technical solution: the fan frame between the groove and the air duct of the fan frame has a mounting groove formed on the connecting rod of the mesh cover.
[0020] The beneficial effect of this improvement is that the opening of the mounting slot prevents the fan frame from obstructing the normal installation of the mesh cover.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0028] Example 1: As Figure 1 As shown in Figure 2, a fan guard fixing structure for easy installation includes a fan frame 1 and a guard 2. The fan frame 1 has grooves 3 on its front and back ends to accommodate the ends of the guard 2. The inner wall of the grooves 3 is formed with protrusions 5. The ends of the guard 2 are fitted between the protrusions 5 and the grooves 3. By designing the grooves 3 and protrusions 5 on the fan frame 1, the guard 2 can be quickly fixed without manual support or fixtures, thus simplifying the installation process, reducing labor costs, and improving installation efficiency. The inner wall of the grooves 3 fits and conforms to the ends of the connecting rods of the guard 2. The grooves 3 are shaped according to the specific shape of the ends of the guard 2 to limit the position of the guard 2, preventing translation of the guard 2 relative to the fan frame 1 and ensuring the guard 2 is properly positioned relative to the fan frame 1. The stability of the frame 1 connection is ensured by the fact that the end face of the protrusion 5 facing the fan frame 1 is an arc-shaped structure, and the end of the mesh cover 2, which can be made of different elastic materials, can slide along the bottom surface of the protrusion 5. After being squeezed and deformed, it will generate elastic deformation and separate from the fan frame 1. The connecting rod of the mesh cover 2 is bent and tilted in the axial direction of the inner and outer rings of the mesh cover 2. The elastic connecting rod of the protruding mesh cover 2 can more easily generate elastic deformation when the end is inserted between the protrusion 5 and the fan frame 1, thereby improving the ease of installation of the mesh cover 2. The mounting groove 6 between the groove 3 and the air duct of the fan frame 1 is formed on the fan frame 1 to adapt to the installation of the connecting rod of the mesh cover 2. The opening of the mounting groove 6 avoids the fan frame 1 from obstructing the normal installation of the mesh cover 2.
[0029] The working principle of this technical solution is as follows: Align the mesh cover 2 with the groove 3 on the fan frame 1, so that the end of the connecting rod of the mesh cover 2 fits against the inner wall of the groove 3. Since the shape of the groove 3 is designed according to the end of the mesh cover 2, the mesh cover 2 will be initially positioned on the fan frame 1 at this time, avoiding translation during installation. Slightly tilt the mesh cover 2 so that the ends of the two adjacent connecting rods of the mesh cover 2 are first inserted between the protrusion 5 and the groove 3. Then, squeeze the ends of the other two connecting rods of the mesh cover 2 to make them produce inward elastic deformation. Since the connecting rods of the mesh cover 2 are bent and tilted in the axial direction of the inner and outer rings of the mesh cover 2, they have a certain degree of elasticity and will produce elastic deformation when squeezed. As the mesh cover 2 gets closer, the end of the mesh cover 2 is finally stuck between the protrusion 5 and the groove 3, completing the installation. In this process, the mounting groove 6 provides installation space for the connecting rods of the mesh cover 2, avoiding the fan frame 1 from obstructing the installation of the mesh cover 2.
[0030] Example 2: As Figure 3 As shown in Figure 4: A fan cover fixing structure that is easy to install includes a fan frame 1 and a fan cover 2. The front and back ends of the fan frame 1 are connected to the mounting plate 7 by bolts. The inner wall of the mounting plate 7 is formed with protrusions 5. The end of the fan cover 2 is snapped between the protrusions 5 and the fan frame 1.
[0031] The beneficial effects of this utility model are as follows: by installing a compact mounting plate 7 on the fan frame 1 with bolts, the mesh cover 2 can be quickly snapped and fixed without manual support or tooling; and the mounting plate 7 can be quickly and effortlessly replaced after wear or breakage.
