Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, specifically to a wind turbine. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas; it is a type of driven fluid machinery.

[0003] Existing fans are mainly composed of impellers, casings, motors and other components. When the motor starts, it drives the impeller to rotate, so that the gas enters the impeller axially from the air inlet. The gas energy is increased by the pushing of the blades on the impeller, and then flows into the guide vanes. The guide vanes deflect the airflow into axial flow and guide the gas into the diffuser, further converting the gas kinetic energy into pressure energy, and finally introducing it into the working pipeline.

[0004] Currently, after a period of use, dust will adhere to the surface of the impeller of existing fans. In order to ensure the performance of the impeller, it is necessary to wipe and clean the impeller to remove the dust adhering to the surface. However, since the impeller is located inside the casing, it is difficult to wipe the back side, which makes the cleaning operation inconvenient, time-consuming and laborious. Utility Model Content

[0023] 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 protection scope of the present utility model.

[0024] Please see Figure 1-3 As shown, a fan includes a housing 1, inside which a motor 2 is housed, and an impeller 3 is connected to the output end of the motor 2. Several supports are also installed inside the housing 1. These supports are made of stainless steel, which has high strength and hardness and is not easily corroded, thus providing good durability. Clamping spaces are formed between the supports for the motor 2 to be engaged. Each support includes a support bar 4. One end of the support bar 4 has a fixing piece 5 fixed to the inner wall of the housing 1, and the other end has a connecting piece 6 for contacting the side wall of the motor 2. The connecting piece 6 is detachably connected to the side wall of the motor 2 via a fixing assembly. Therefore, when cleaning the impeller 3, the fixing assembly can be released from the connecting piece 6, separating the connecting piece 6 from the motor 2, allowing the motor 2 and impeller 3 to be completely removed from the housing 1 for easy cleaning. The impeller 3 is wiped clean. Since the casing 1 is no longer needed to block it, the cleaning is more thorough and the operation is more convenient. After cleaning, the motor 2 can be re-clamped into the clamping space, so that the connecting piece 6 abuts against the side wall of the motor 2. Then, the connecting piece 6 is fixedly connected to the side wall of the motor 2 by the fixing component, thereby realizing the secure installation of the motor 2 inside the casing 1, and the impeller 3 is reset. The whole operation is convenient and simple, saving time and effort. Among them, an elastic pad 13 is provided on the side of the connecting piece 6 away from the support bar 4. The elastic pad 13 is made of rubber material. After the connecting piece 6 is connected to the motor 2, the elastic pad 13 will deform under the pressure of the connecting piece 6 and the side wall of the motor 2, thereby making the connection between the connecting piece 6 and the motor 2 more stable, reducing shaking, and ensuring the installation reliability of the motor 2.

[0025] Please see Figure 2-6As shown, a slot 7 is provided on the connecting piece 6. The fixing component includes a connecting pin 8 for engaging with the slot 7, and a fastener 9 for abutting against the connecting piece 6 is connected to the connecting pin 8. The connecting pin 8 is fixedly connected to the side wall of the motor 2. When the motor 2 needs to be installed, the connecting piece 6 can be abutted against the side wall of the motor 2. During this process, the connecting pin 8 will engage with the slot 7 to achieve pre-positioning. Then, the fastener is connected to the connecting pin 8 until it abuts against the connecting piece 6, thereby pressing the connecting piece 6 firmly against the side wall of the motor 2. This ensures a secure installation of motor 2. When disassembly is required, simply remove fastener 9 from connecting pin 8 and slide connecting pin 8 out of slot 7 to remove motor 2. The entire disassembly and assembly operation is convenient and simple. The connecting pin 8 has an external thread structure on its side wall, and the fastener 9 has an internal thread structure matching the external thread structure on its inner side wall. Therefore, fastener 9 can be connected to connecting pin 8 via a threaded connection, providing good connection security and ensuring the secure installation of motor 2. By unscrewing the fastener 9 from the connecting pin 8, the fixing of the connecting piece 6 can be released, making it easy to remove the motor 2. A groove 10 is provided in the slot 7, and a retaining ring 11 is provided on the fastener 9 for embedding into the groove 10. After the fastener 9 is connected to the connecting pin 8, the retaining ring 11 will also embed into the groove 10. The retaining ring 11, limited by the groove 10, makes the connection between the fastener 9 and the connecting pin 8 more secure, thereby improving the installation stability of the motor 2. The retaining ring 11 is made of rubber material. With good elasticity, after the insert ring 11 is inserted into the insert groove 10, it will undergo elastic deformation due to the compression of the fastener 9, thereby applying a thrust to the fastener 9 in the opposite direction, making the threaded connection between the fastener 9 and the connecting pin 8 tighter, thus further improving the installation firmness of the motor 2. Among them, several protrusions 12 are provided on the side wall of the fastener 9. The protrusions 12 greatly increase the friction coefficient on the side wall of the fastener 9, making it less likely to slip when tightening the fastener 9, and making the operation easier and less strenuous.
