Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blades, and more specifically, to a novel fan blade reinforcement structure. Background Art
[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge the gas. It is a driven fluid mechanical device. In China, fan is often used as an abbreviation for gas compression and gas transmission mechanical equipment. Commonly referred to as fans include ventilators, blowers, wind turbines, etc. The working principle of a fan is basically the same as that of a turbine compressor, but because the gas flow rate is low and the pressure change is not large, it is generally not necessary to consider the change in gas specific volume. In other words, the gas is treated as an incompressible fluid.
[0003] Wind turbine blades, particularly those used in wind turbines, are a core component of wind turbines, accounting for approximately 15% to 20% of the total cost. Their design directly impacts turbine performance and profitability. A wind turbine blade is a thin, composite shell structure consisting of a root, outer shell, and keel. Blades come in a variety of styles, including pointed, flat, hooked, and flapped tips.
[0004] Among them, after searching, it was found that the patent application number CN201721718281.X discloses a wind turbine blade reinforcement structure, including a base and a blade installed outside the base, characterized in that: the base and the blade are connected by a reinforcing rib structure, the reinforcing rib structure includes a first reinforcing rib connected to the base and a second reinforcing rib connected to the blade, and the first reinforcing rib and the second reinforcing rib are connected to each other;
[0005] When this structure is in use, it is connected to the corresponding base and blade respectively through the first reinforcing rib and the second reinforcing rib, and the first reinforcing rib and the second reinforcing rib are connected to each other. On the basis of enhancing the structural strength of the blade itself, it also increases the connection strength between the blade and the base. However, when this structure is in use, the blade will be deformed due to long-term obstruction, resulting in low fluid transportation efficiency. Utility Model Content

[0012] It can be seen that, in the above technical solution, the support cylinder, the reinforcing cylinder and the limiting clamping groove facilitate the output end of an external driving device such as a motor to extend into the reinforcing cylinder, and the limiting clamping groove limits the stability during transmission.
[0013] Technical effects and advantages of the utility model:

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] As attached Figure 1-5 The novel fan blade reinforcement structure shown in the figure has a connecting assembly provided on the base 1, which can pass through the conical cross-section of the reinforced support cone column 2, so that the first reinforced blade 3 can be tilted when installed, facilitating fluid transportation. The second reinforced blade 6 diverts the fluid transported by the first reinforced blade 3 when it rotates, which not only improves transportation efficiency but also prevents fluid accumulation. At the same time, the tightening ring 5 can limit the first reinforced blade 3, locking it on the reinforced support cone column 2, preventing the first reinforced blade 3 from deformation and extending the service life of the structure. The specific structural arrangement of the assembly is as follows;
[0025] The connecting assembly includes a reinforced support cone column 2 provided on the top of the base 1. The vertical cross-section of the reinforced support cone column 2 is set to be conical. A plurality of first reinforced blades 3 are distributed on the outside of the reinforced support cone column 2, and each first reinforced blade 3 is connected to the reinforced support cone column 2.
[0026] A tight ring 5 is sleeved on the outer side of the first reinforcing blade 3, and a number of second reinforcing blades 6 are distributed on the bottom of the tight ring 5. A supporting cylinder 4 is provided in the middle of the reinforcing support cone column 2, and the bottom of the supporting cylinder 4 extends to the base 1. A reinforcing cylinder 7 is provided inside the supporting cylinder 4, and a limiting slot 8 is provided on one side of the inner wall of the reinforcing cylinder 7.
[0027] The vertical cross-sectional shapes of the multiple support cylinders 4 are all set to be arc-shaped, and a first guide cavity 9 is formed between each adjacent two support cylinders 4. The cross-sectional shapes of the multiple second reinforcement blades 6 are all set to be arc-shaped, and a second guide cavity 10 is formed between each adjacent two second reinforcement blades 6. The tight hoop 5 is located at the bottom of several first reinforcement blades 3, and the tight hoop 5 is detachably connected to the first reinforcement blades 3.
[0028] According to the above structure, when using, the staff installs the device at a designated position, with the base 1 as the support point. The first reinforcement blades 3 are distributed on the outside of the reinforced support cone column 2. The conical cross section of the reinforced support cone column 2 allows the first reinforcement blades 3 to be tilted when installed, making it easier to transport the fluid.
[0029] At the same time, through the support cylinder 4, the reinforcement cylinder 7 and the limit slot 8, it is easy for external driving equipment, such as the output end of the motor, to extend into the reinforcement cylinder 7 and be limited by the limit slot 8 to ensure stability during transmission;
[0030] At the same time, through the arrangement of the tight ring 5 and the second reinforcing blade 6, the second reinforcing blade 6 diverts the fluid transported by the first reinforcing blade 3 when it rotates, which not only improves the transport efficiency but also avoids fluid accumulation. At the same time, the tight ring 5 can limit the first reinforcing blade 3 and lock it on the reinforced support cone column 2, thereby avoiding deformation of the first reinforcing blade 3 and extending the service life of the structure.
[0031] Different from the existing technology, the present application discloses a new type of fan blade reinforcement structure. By reinforcing the conical cross-section of the supporting cone column 2, the first reinforced blade 3 can be tilted during installation, which is convenient for fluid transportation. The second reinforced blade 6 diverts the fluid transported by the first reinforced blade 3 when it rotates, which not only improves the transportation efficiency but also avoids fluid accumulation. At the same time, the tight ring 5 can limit the first reinforced blade 3 and lock it on the reinforced supporting cone column 2, thereby avoiding deformation of the first reinforced blade 3 and extending the service life of the structure.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
