Description

Technical Field

[0001] This utility model relates to the field of impeller fan technology, and in particular to a split-type installation structure for an impeller fan that is convenient for transportation in mountainous areas. 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. In China, "fan" is a common abbreviation for gas compression and gas transportation machinery. The term "fan" usually includes ventilators, blowers, and wind turbines.

[0003] As shown in the reference case "A Combined Wind Turbine Impeller" (Announcement No. CN217898263U), by setting the chassis, upper ring, and multiple blades as a separate structure, and by setting a sliding cylinder, fixing column, operating knob, spiral compression spring, insert block, slot, and locking block between the upper ring and the chassis, tool-free combination and fixing operation between the chassis, upper ring, and multiple blades can be realized, which effectively reduces the workload of operators in installing and disassembling the wind turbine impeller, thereby improving the convenience of wind turbine impeller installation and disassembly.

[0004] Although existing impeller fans have a detachable design that can reduce the overall transport volume to some extent, the disassembled impeller, chassis, upper ring and other components are stored independently and cannot be effectively stacked or nested. During transportation in mountainous areas, due to narrow roads and limited transportation conditions, each component of the fan still needs to occupy a large space.

[0005] Therefore, a split-type installation structure for impeller fans that facilitates transportation in mountainous areas is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a split-type installation structure for impeller fans that facilitates transportation in mountainous areas in order to solve the above-mentioned problems. This improves the problem that although existing impeller fans have a detachable design, which can reduce the overall transportation volume to a certain extent, the disassembled impeller, chassis, upper ring and other components are stored independently and cannot be effectively stacked or nested. In mountainous areas, due to narrow roads and limited transportation conditions, the various components of the fan still occupy a large amount of space.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a split-type installation structure for a turbine fan that facilitates transportation in mountainous areas, comprising: a base, on one side of which an impeller frame is provided; and a stacking and splitting mechanism, which is provided between the base and the impeller frame for stacking the disassembled components after the turbine fan is disassembled. The stacking and splitting mechanism includes multiple connecting plates fixedly installed between the base and the impeller frame, a stacking assembly is provided between the base and the impeller frame, and a placement assembly is provided on one side of the base. After the base and impeller frame are disassembled, the internal components can be stacked using the stacking assembly, reducing the overall transportation size and making it more suitable for transportation on narrow mountain roads. Furthermore, the base and impeller frame can be aligned using the placement assembly during use, further saving transportation space and making the turbine fan easier to transport.

[0008] Preferably, the stacking assembly includes multiple blades disposed between the base and the impeller frame. A guide block is fixedly installed on one side of each blade, and a stacking slot is formed on the other side of each blade. The guide block is adapted to the shape of the stacking slot, and both sides of the guide block are rounded. After the base and the impeller frame are separated, the multiple blades are interconnected with the corresponding stacking slots through the guide blocks, so that the multiple blades can be stacked and stored in a compact manner, reducing volume, improving transportation efficiency, and adapting to the transportation needs of mountainous areas.

[0009] Preferably, two locking blocks are fixedly installed on both sides of the plurality of blades. Multiple mounting holes corresponding to the locking blocks are opened on the surfaces of the impeller frame and the base. The two locking blocks on both sides of the blade are slidably engaged with the adjacent mounting holes. When installing the blade, the blade can be installed simply by sliding the two locking blocks on both sides of the blade with the corresponding mounting holes on the surfaces of the base and the impeller frame. This improves the rapid assembly capability of the wind turbine in mountainous areas and makes it more suitable for the rapid deployment of wind turbines in mountainous areas.

[0010] Preferably, one side of the connecting plate is slidably mounted on the surface of the base, and a screw is rotatably mounted on the other side of the connecting plate. Multiple screw holes are opened on the outer side of the impeller frame, and the screw is threadedly connected to the adjacent screw holes. Multiple connecting plates are arranged in a ring around one side of the base. When installing the base and the impeller frame, multiple connecting plates can be slidably connected to the base first, and then the impeller frame can be placed between the multiple connecting plates. The screw is used to connect the impeller frame to the connecting plates. The connection steps are simple and easy to understand. Moreover, the connecting plates are arranged in a ring, which can provide stable support in multiple directions, ensuring that the impeller frame will not tilt or shift during installation, thus improving the stability of the overall structure.

[0011] Preferably, the connecting plate is configured as an arc shape, and multiple connecting plates are located on the outside of multiple blades. The arc-shaped connecting plate can maintain stability during high-speed rotation and reduce offset or shaking.

[0012] Preferably, the placement assembly includes multiple alignment blocks fixedly installed inside the base, and multiple fixing blocks fixedly installed on the inner side of the impeller frame. Each fixing block is aligned with the multiple alignment blocks, and the surface of the fixing blocks is provided with alignment holes. After the base and the impeller frame are separated, the impeller frame is brought close to the base and slidably connected with the multiple alignment blocks through the alignment holes of the multiple fixing blocks, so that the two can be fixedly placed together during transportation in mountainous areas to reduce transportation shaking damage.

[0013] Preferably, a shaft is provided on one side of the base, and an installation ring is fixedly installed on the outer side of the shaft. The installation ring is threadedly connected to the base. The threaded connection of the installation ring can be completed by simply rotating the installation ring, without any additional complicated operations. This method is suitable for the rapid assembly and on-site installation of wind turbines in mountainous areas.

[0014] The beneficial effects of this utility model are:

[0015] 1. After the base and impeller frame are disassembled, the internal components can be stacked using the stacking assembly, reducing the overall transport size and making it more suitable for transporting on narrow mountain roads. Furthermore, the base and impeller frame can be aligned using the stacking assembly during use, further saving transport space and making the impeller fan easier to transport.

[0016] 2. After the base and impeller frame are separated, the impeller frame is brought close to the base and slidably connected with multiple alignment blocks through the alignment holes of multiple fixing blocks, so that the two can be fixed together during transportation in mountainous areas to reduce transportation shaking damage.

Detailed Implementation

[0022] 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.

[0023] In practical implementation: such as Figure 1-4 As shown, a split-type installation structure for a turbine fan that facilitates transportation in mountainous areas includes: a base 1, with an impeller frame 2 disposed on one side of the base 1; and a stacking and splitting mechanism 3, which is disposed between the base 1 and the impeller frame 2 for stacking the disassembled components of the turbine fan. The stacking and splitting mechanism 3 includes multiple connecting plates 31 fixedly installed between the base 1 and the impeller frame 2, a stacking assembly 32 disposed between the base 1 and the impeller frame 2, and a placement assembly 33 disposed on one side of the base 1. After the base 1 and the impeller frame 2 are disassembled, the internal components can be stacked using the stacking assembly 32, reducing the overall transportation size and making it more suitable for transportation on narrow mountain roads. Furthermore, the base 1 and the impeller frame 2 can be aligned using the placement assembly 33 during use, further saving transportation space and making the turbine fan easier to transport.

[0024] The stacking assembly 32 and placement assembly 33 in this impeller fan are only used when the fan is stacked after disassembly and do not participate in the normal operation process of the impeller fan. Therefore, they will not affect the normal function and use of the impeller fan.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the stacking assembly 32 includes multiple blades 321 disposed between the base 1 and the impeller frame 2. A guide block 324 is fixedly installed on one side of each blade 321, and a stacking slot 325 is formed on the other side of each blade 321. The guide block 324 is shaped to match the stacking slot 325, and both sides of the guide block 324 are rounded. After the base 1 and the impeller frame 2 are separated, the multiple blades 321 are interconnected with the corresponding stacking slots 325 through the guide block 324, allowing the multiple blades 321 to be stacked in a compact manner, reducing volume, improving transportation efficiency, and adapting to the transportation needs of mountainous areas. The guide block 324 and the stacking slot 325 of the blade 321 are only connected on the blade 321. 1. When stacked, it will not affect the overall operation of the wind turbine or the normal use of the blades 321. Two locking blocks 322 are fixedly installed on both sides of multiple blades 321. Multiple mounting holes 323 corresponding to the locking blocks 322 are opened on the surface of the impeller frame 2 and the base 1. The two locking blocks 322 on both sides of the blade 321 are slidably engaged with the adjacent mounting holes 323. When installing the blades 321, simply slide the two locking blocks 322 on both sides of the blades 321 with the corresponding mounting holes 323 on the surface of the base 1 and the impeller frame 2 to complete the installation of the blades 321, improve the rapid assembly capability of wind turbines in mountainous areas, and make them more suitable for the rapid deployment of wind turbines in mountainous areas.

[0026] One side of the connecting plate 31 is slidably mounted on the surface of the base 1, and the other side of the connecting plate 31 is rotatably mounted with a screw 326. Multiple screw holes 327 are opened on the outer side of the impeller frame 2. The screw 326 is threadedly connected to the adjacent screw holes 327. Multiple connecting plates 31 are arranged in a ring around one side of the base 1. When installing the base 1 and the impeller frame 2, the multiple connecting plates 31 can be slidably connected to the base 1 first, and then the impeller frame 2 can be placed between the multiple connecting plates 31. The screw 326 is used to connect the impeller frame 2 to the connecting plates 31. The connection steps are simple and easy to understand. The connecting plates 31 are arranged in a ring, which can provide stable support in multiple directions, ensuring that the impeller frame 2 will not tilt or shift during installation, thus improving the stability of the overall structure. The connecting plates 31 are set in an arc shape. Multiple connecting plates 31 are located on the outer side of multiple blades 321. The arc-shaped connecting plates 31 can maintain stability during high-speed rotation and reduce offset or shaking.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the placement component 33 includes multiple alignment blocks 331 fixedly installed inside the base 1, and multiple fixing blocks 332 fixedly installed on the inner side of the impeller frame 2. The multiple fixing blocks 332 are aligned with the multiple alignment blocks 331. The surface of the fixing blocks 332 is provided with alignment holes 333. After the base 1 and the impeller frame 2 are separated, the impeller frame 2 is brought close to the base 1 and slidably connected with the multiple alignment blocks 331 through the alignment holes 333 of the multiple fixing blocks 332. This allows the two to be fixedly placed together during transportation in mountainous areas to reduce transportation shaking damage. A shaft 21 is provided on one side of the base 1, and an installation ring 334 is fixedly installed on the outer side of the shaft 21. The installation ring 334 is threadedly connected to the base 1. The threaded connection of the installation ring 334 can be completed by simply rotating the installation ring 334 to connect the fan to the base 1 without additional complicated operations. This is suitable for the rapid assembly and on-site installation of fans in mountainous areas.

[0028] In use, after the base 1 and impeller frame 2 are separated, multiple blades 321 are interconnected with corresponding stacking slots 325 via guide blocks 324. This allows multiple blades 321 to be stacked compactly, reducing volume, improving transportation efficiency, and adapting to the transportation needs of mountainous areas. When installing the blades 321, simply slide the two locking blocks 322 on both sides of the blade 321 into the corresponding mounting holes 323 on the surfaces of the base 1 and impeller frame 2 to complete the installation. This improves the rapid assembly capability of wind turbines in mountainous areas and is more suitable for rapid deployment. When installing the base 1 and impeller frame 2, multiple connecting plates 31 can be slidably connected to the base 1 first, and then the impeller frame 2 can be placed on the multiple connecting plates. Between the plates 31, the impeller frame 2 is connected to the connecting plate 31 using screws 326. The connection steps are simple and easy to understand. The connecting plate 31 adopts a wraparound arrangement, which can provide stable support in multiple directions, ensuring that the impeller frame 2 will not tilt or shift during installation. After the base 1 and the impeller frame 2 are separated, the impeller frame 2 is brought close to the base 1 and slidably connected to the multiple alignment blocks 331 through the alignment holes 333 of the multiple fixing blocks 332. This allows the two to be fixed together during transportation in mountainous areas, reducing transportation shaking damage. The threaded connection of the mounting ring 334 only requires rotating the mounting ring 334 to complete the connection between the fan and the base 1. No additional complicated operations are required, making it suitable for the rapid assembly and on-site installation of fans in mountainous areas.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
