Description

Technical Field

[0001] This utility model relates to the technical field of cross-flow fan impeller equipment, and in particular to a counterweight fixture for a cross-flow fan impeller. Background Technology

[0002] Cross-flow wind turbine impeller counterweight fixtures are mainly used for balancing and adjusting wind turbine impellers. Because the impeller is affected by centrifugal force when it is running at high speed, uneven mass distribution can lead to vibration or damage. The counterweight fixture ensures uniform mass distribution of the impeller by precisely adding counterweights, thereby improving the operational stability and lifespan of the equipment. This technology is widely used in wind power generation, air conditioning and ventilation equipment and other fields.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing cross-flow fan impeller counterweight fixture cannot achieve stable balance adjustment of the impeller. Impeller imbalance will cause additional centrifugal force to be generated when rotating at high speed, which will cause the vibration of the entire system to be aggravated, and thus generate greater noise. This vibration will not only affect the stability of the equipment, but may also cause interference to the surrounding environment. Long-term unbalanced operation will cause key components such as bearings to bear uneven loads, accelerate the wear process, and thus shorten the service life of the equipment. In addition, excessive vibration may also cause other structural components to loosen or be damaged.

[0004] Therefore, this utility model proposes a counterweight fixture for a cross-flow fan impeller to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a counterweight fixture for a cross-flow fan impeller.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a counterweight fixture for a cross-flow fan impeller, comprising:

[0007] impeller;

[0008] A counterweight assembly is provided, which is placed on both sides of the impeller. The counterweight assembly includes a support base fixed on both sides of the impeller. A first rotating ring is slidably connected in the support base. The first rotating ring has a toothed groove. A limit post is fixedly connected to the side of the first rotating ring away from the impeller. A first limit block is fixedly connected to the support base. A second rotating ring is rotatably connected to the first limit block. The second rotating ring has a limit groove. A counterweight block is fixedly connected to the second rotating ring.

[0009] A buffer assembly is placed on the impeller near the support base. The buffer assembly includes a fixed block fixed on the impeller near the support base. A limit rod is fixedly connected to the fixed block. A connecting plate is slidably connected to the limit rod. A telescopic spring is provided on the limit rod. A spring sheet is provided on the fixed block.

[0010] In a preferred embodiment, the limiting post is slidably connected within the limiting groove.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, since the limiting post is slidably connected in the limiting groove, when the limiting post rotates, through the cooperation of the limiting post and the limiting groove, the limiting post will drive the second rotating ring to rotate on the first limiting block, so that the position of the counterweight can be adjusted.

[0012] In a preferred embodiment, a gear is rotatably connected to the side of the impeller near the tooth groove, and the gear meshes with the tooth groove.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since a gear is rotatably connected to the side of the impeller near the tooth groove, and the gear meshes with the tooth groove, the rotating gear, through the cooperation of the tooth groove and the gear, will drive the first rotating ring to rotate in the support seat.

[0014] In a preferred embodiment, one end of the telescopic spring is fixedly connected to the fixing block, and the other end of the telescopic spring is fixedly connected to the connecting plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, since one end of the telescopic spring is fixedly connected to the fixed block and the other end of the telescopic spring is fixedly connected to the connecting plate, the telescopic spring can provide elastic force to the connecting plate.

[0016] In a preferred embodiment, one end of the spring is fixedly connected to the fixing block, and the other end of the spring is fixedly connected to the connecting plate.

[0017] The beneficial effects of adopting the above-mentioned further solution are: since one end of the spring is fixedly connected to the fixed block and the other end of the spring is fixedly connected to the connecting plate, the spring can provide elastic force to the connecting plate. Through the cooperation of the telescopic spring and the spring, it can provide strong vibration reduction and buffering effect to the impeller.

[0018] In a preferred embodiment, a second limiting block is fixedly connected to one end of the limiting rod away from the fixed block.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, since a second limiting block is fixedly connected to the end of the limiting rod away from the fixed block, when the connecting plate moves on the limiting rod, the second limiting block can limit the movement of the connecting plate and prevent the connecting plate from falling off the limiting rod.

[0020] In a preferred embodiment, a connecting shaft is fixedly connected to the side of the connecting plate away from the impeller.

[0021] The beneficial effect of adopting the above-mentioned further solution is that, since a connecting shaft is fixedly connected to the side of the connecting plate away from the impeller, the connecting shaft can be connected to the transmission mechanism.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, the counterweight fixture structure achieves balance adjustment of the impeller by setting counterweight components on both sides of the impeller. The counterweight components include a support base, a first rotating ring, and a second rotating ring. The first rotating ring has a toothed groove for engaging with a gear. When the gear is rotated, it drives the first rotating ring to rotate, thus fixing and rotating the rotating ring. The second rotating ring has a limiting groove for engaging with a limiting post. When the limiting post moves within the limiting groove, it drives the second rotating ring to rotate, causing the counterweight fixed on the second rotating ring to rotate. By adjusting the position of the counterweight, the center of gravity of the impeller can be changed, thereby achieving balance adjustment of the impeller. Attached Figure Description

[0032] 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.

[0033] like Figures 1-4 As shown, this embodiment provides a technical solution: a counterweight fixture for a cross-flow fan impeller, comprising:

[0034] Impeller 1;

[0035] The counterweight assembly 2 is placed on both sides of the impeller 1. The counterweight assembly 2 includes a support base 21 fixed on both sides of the impeller 1. A first rotating ring 22 is slidably connected in the support base 21. The first rotating ring 22 has a toothed groove 23. A limit post 24 is fixedly connected to the side of the first rotating ring 22 away from the impeller 1. A first limit block 25 is fixedly connected to the support base 21. A second rotating ring 26 is rotatably connected to the first limit block 25. A limit groove 27 is opened on the second rotating ring 26. A counterweight block 28 is fixedly connected to the second rotating ring 26.

[0036] A buffer assembly 3 is placed on the impeller 1 near the support base 21. The buffer assembly 3 includes a fixing block 31 fixed to the impeller 1 near the support base 21. A limit rod 32 is fixedly connected to the fixing block 31, and a connecting plate 33 is slidably connected to the limit rod 32. A telescopic spring 34 is provided on the limit rod 32, and a spring piece 36 is provided on the fixing block 31. This counterweight fixture structure achieves the balance adjustment of the impeller 1 by setting counterweight assemblies 2 on both sides of the impeller 1. The counterweight assembly 2 includes a support base 21, a first rotating ring 22, and a second rotating ring 26. The first rotating ring 22 has a toothed groove 23 for engaging with a gear 29. When the gear 29 rotates, it drives the first rotating ring 22 to rotate, achieving both fixing and rotation of the rotating ring. The second rotating ring 26 has a limit groove 27 for... In conjunction with the limiting post 24, when the limiting post 24 moves within the limiting groove 27, the limiting post 24 will drive the second rotating ring 26 to rotate, causing the counterweight block 28 fixed on the second rotating ring 26 to rotate. By adjusting the position of the counterweight block 28, the center of gravity position of the impeller 1 can be changed, thereby achieving the balance adjustment of the impeller 1. The buffer assembly 3 is placed on the side of the impeller 1 near the support seat 21 to reduce the vibration and noise generated by the impeller 1 during operation. The buffer assembly 3 includes components such as a fixed block 31, a limiting rod 32, a connecting plate 33, and a telescopic spring 34. When the impeller 1 is running, due to the centrifugal force, the connecting plate 33 will move along the limiting rod 32, thereby compressing or stretching the telescopic spring 34 to play a buffering role. At the same time, the spring sheet 36 can also absorb some vibration energy, further reducing vibration and noise.

[0037] The above solutions still have the problem that, while impeller 1 is in operation, they cannot effectively reduce the vibration and noise generated during its operation. Figures 1-3 As shown: The limiting post 24 is slidably connected in the limiting groove 27. Because the limiting post 24 is slidably connected in the limiting groove 27, when the limiting post 24 rotates, through the cooperation of the limiting post 24 and the limiting groove 27, the limiting post 24 will drive the second rotating ring 26 to rotate on the first limiting block 25, so that the position of the counterweight block 28 can be adjusted. A gear 29 is rotatably connected on the side of the impeller 1 near the tooth groove 23. The gear 29 meshes with the tooth groove 23. Because the gear 29 is rotatably connected on the side of the impeller 1 near the tooth groove 23, and the gear 29 meshes with the tooth groove 23, rotating the gear 29, through the cooperation of the tooth groove 23 and the gear 29, will drive the first rotating ring 22 to rotate in the support seat 21.

[0038] like Figure 1 as well as Figure 4As shown, one end of the telescopic spring 34 is fixedly connected to the fixing block 31, and the other end of the telescopic spring 34 is fixedly connected to the connecting plate 33. Because one end of the telescopic spring 34 is fixedly connected to the fixing block 31 and the other end is fixedly connected to the connecting plate 33, the telescopic spring 34 can provide elastic force to the connecting plate 33. One end of the spring piece 36 is fixedly connected to the fixing block 31, and the other end of the spring piece 36 is fixedly connected to the connecting plate 33. Because one end of the spring piece 36 is fixedly connected to the fixing block 31 and the other end is fixedly connected to the connecting plate 33, the spring piece 36 can provide elastic force to the connecting plate 33. Through the telescopic spring 34... The cooperation of 4 and spring 36 can provide strong vibration reduction and buffering for impeller 1. A second limiting block 35 is fixedly connected to the end of the limiting rod 32 away from the fixed block 31. Since the second limiting block 35 is fixedly connected to the end of the limiting rod 32 away from the fixed block 31, when the connecting plate 33 moves on the limiting rod 32, the second limiting block 35 can limit the movement of the connecting plate 33 and prevent the connecting plate 33 from falling off the limiting rod 32. A connecting shaft 37 is fixedly connected to the side of the connecting plate 33 away from the impeller 1. Since the connecting shaft 37 is fixedly connected to the side of the connecting plate 33 away from the impeller 1, the connecting shaft 37 can be connected to the transmission mechanism.

[0039] Working principle:

[0040] like Figures 1-4 As shown, this counterweight fixture structure achieves balance adjustment of the impeller 1 by setting counterweight components 2 on both sides of the impeller 1. The counterweight components 2 include a support base 21, a first rotating ring 22, and a second rotating ring 26. The first rotating ring 22 has a toothed groove 23 for engaging with a gear 29. When the gear 29 is rotated, it drives the first rotating ring 22 to rotate, thus fixing and rotating the rotating ring. The second rotating ring 26 has a limiting groove 27 for engaging with a limiting post 24. When the limiting post 24 moves within the limiting groove 27, it drives the second rotating ring 26 to rotate, thus fixing the second rotating ring 26. The counterweight 28 rotates, and by adjusting the position of the counterweight 28, the center of gravity of the impeller 1 can be changed, thereby achieving the balance adjustment of the impeller 1. The buffer assembly 3 is placed on the side of the impeller 1 near the support seat 21 to reduce the vibration and noise generated by the impeller 1 during operation. The buffer assembly 3 includes components such as a fixed block 31, a limiting rod 32, a connecting plate 33, and a telescopic spring 34. When the impeller 1 is running, due to the centrifugal force, the connecting plate 33 will move along the limiting rod 32, thereby compressing or stretching the telescopic spring 34, which plays a buffering role. At the same time, the spring sheet 36 can also absorb some vibration energy, further reducing vibration and noise.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
