[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a hoisting structure, a fan settling device, and an air conditioner. Background Technology

[0002] With the widespread application of 4G and the gradual popularization of 5G, the heat generated by various data processing devices is increasing, and data centers are placing higher demands on the cooling capacity and energy efficiency of their air conditioning equipment. In downflow precision computer room air conditioning units, placing centrifugal fans outside the unit can significantly improve its air delivery efficiency, and therefore it has been widely used in engineering.

[0003] In existing wind turbine lifting structure solutions, the weight of the wind turbine components fixed on the base is borne by the base of the cabinet. The sheet metal parts of the base have excessive load-bearing capacity, which is not conducive to long-distance transportation and reliable operation of the wind turbine components. Utility Model Content

[0005] To solve the above problems, this utility model provides a hoisting structure, including a hoisting assembly, wherein the hoisting assembly is provided with hoisting parts for hoisting and lifting the fan assembly;

[0006] The hoisting structure also includes a limiting structure for limiting the lifting and lowering of the wind turbine assembly; the hoisting assembly is provided with a drive worm gear, and the hoisting component has a gear segment, with the drive worm gear meshing with the gear segment; the hoisting component is used to be threadedly connected to the wind turbine assembly to hoist the wind turbine assembly; the drive worm gear is driven to rotate the hoisting component through the gear segment, causing the hoisting component to lift the wind turbine assembly to a first position or lower it to a second position.

[0007] In some embodiments, the lifting member has a screw section connected to the gear segment, and the lifting member is threadedly connected to the wind turbine assembly via the screw section.

[0008] In some embodiments, one end of the drive worm gear is provided with a polygonal groove for connecting to an external drive tool, so that the external drive tool can drive the drive worm gear to rotate through the polygonal groove.

[0009] In some embodiments, there are two drive worm gears, and the gear segment of the lifting component is sandwiched between the two drive worm gears.

[0010] In some embodiments, the lifting assembly has a crossbeam with mounting slots on it, and both drive worm gears are rotatably mounted in the mounting slots.

[0011] In some embodiments, the number of lifting components is two or more, and each of the lifting components cooperates to form the limiting structure.

[0012] In some embodiments, the hoisting structure further includes a locking structure for securing the wind turbine assembly to the hoisting assembly when the wind turbine assembly is raised to the first position or lowered to the second position.

[0013] This utility model also provides a wind turbine settling device, which includes the aforementioned wind turbine assembly and the hoisting structure described in any one of the above descriptions.

[0014] In some embodiments, the fan assembly includes a fan, a guide ring, a base plate, and a first fixing column. The guide ring is disposed at the upper end of the fan, and the base plate is disposed at the lower end of the fan. The first fixing column is used to connect the guide ring and the base plate. The first fixing column is provided with a first threaded hole, and the fan assembly is threadedly connected to the hoisting component through the first threaded hole.

[0015] In some embodiments, when the hoisting structure further includes a locking structure, and the locking structure is used to lock the fan assembly onto the hoisting assembly when the fan assembly is raised to a first position or lowered to a second position, the hoisting assembly has a base with a movable opening for the fan assembly to pass through; when the fan assembly is raised to the first position, the base plate is located above the movable opening, and the fan assembly is locked onto the base by the locking structure through the base plate; and when the fan assembly is lowered to the second position, the base plate is located below the movable opening, the guide ring overlaps the upper end of the movable opening, and the fan assembly is locked onto the base by the locking structure through the guide ring.

[0016] In some embodiments, the base plate is provided with a movable support plate, which can extend or retract from the base plate;

[0017] When the fan assembly rises to the first position, the movable support plate can extend out of the base plate and overlap the upper end of the moving opening, so that the base plate can be locked to the base by the locking structure through the movable support plate; when the fan assembly rises to the first position, the movable support plate can also retract the base plate, so that the base plate can pass through the moving opening.

[0018] In some embodiments, the movable support plate is sleeved on the first fixed post and threadedly connected to the first fixed post. The movable support plate can rotate relative to the first fixed post to extend or retract the base plate by rotation.

[0019] In some embodiments, the locking structure is a threaded fastener, the base is provided with a second threaded hole for threaded connection with the threaded fastener, and both the movable support plate and the guide ring are provided with fastener through holes for the threaded fastener to pass through.

[0022] The hoisting structure, fan settling device, and air conditioner provided by this utility model have the following beneficial effects:

[0023] 1. This utility model uses a hoisting device to suspend the wind turbine assembly, which can form a top suspension structure for the wind turbine assembly. This reduces the load on the base from the wind turbine assembly and solves the problem of excessive load on the sheet metal parts of the base caused by fixing the wind turbine assembly only to the base in the prior art. This improves the reliability of the wind turbine assembly during long-distance transportation and operation.

[0024] 2. The bottom of the fan assembly is fixed to the base with threaded fasteners, and the top of the fan assembly is suspended from the crossbeam by a lifting device. Therefore, the factory fixing state of the fan assembly is more reliable and effective (bottom fixed + top suspended), which can reduce the impact force of the fan assembly on the base during transportation. In contrast, traditional fan assemblies are only fixed to the base (bottom fixed), which places higher load requirements on the base. Attached Figure Description

[0044] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0045] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0046] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0047] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0048] See also Figure 1-9 As shown, according to an embodiment of the present invention, a hoisting structure is provided, including a hoisting assembly 1. The hoisting assembly 1 is provided with a hoisting component 7 for hoisting and lifting a fan assembly 2.

[0049] The aforementioned hoisting structure also includes a limiting structure, which limits the lifting and lowering of the fan assembly 2. The hoisting assembly 1 is equipped with a drive worm gear 6, and the hoisting component 7 has a gear section 71, with the drive worm gear 6 meshing with the gear section 71. The hoisting component 7 is used for threaded connection with the fan assembly 2 to hoist the fan assembly 2. The drive worm gear 6 is driven to rotate the hoisting component 7 via the gear section 71, causing the hoisting component 7 to lift the fan assembly 2 to a first position or lower it to a second position.

[0050] In the above example, the drive worm 6 is driven to rotate, which in turn drives the gear segment 71 to rotate. The gear segment 71 then drives the entire lifting component 7 to rotate. When the lifting component 7 rotates, it causes the fan assembly 2 to rise to the first position or fall to the second position under the limitation of the limiting structure. Since the lifting component 7 suspends the fan assembly 2, a top suspension structure for the fan assembly 2 can be formed. This reduces the load on the base 11 caused by the fan assembly 2 being fixed only to the base 11 in the prior art, resulting in excessive load on the sheet metal parts of the base 11. This improves the reliability of the fan assembly 2 during long-distance transportation and operation.

[0051] To achieve the function of threaded connection between the lifting component 7 and the wind turbine assembly 2, in some embodiments, such as Figures 5a-5b As shown, the lifting component 7 may have a screw section 72 connected to the gear section 71. The screw section 72 and the gear section 71 are integrally formed to improve the connection stability between the screw section 72 and the gear section 71. The lifting component 7 is threadedly connected to the fan assembly 2 through the screw section 72.

[0052] like Figures 5a-5b As shown, one end of the aforementioned lifting component 7 is a gear segment 71, which is an external gear structure. The other end of the lifting component 7 is a screw segment 72, which is an externally threaded structure. Another polygonal groove 70 may also be formed along the central axis on the end face of the gear segment 71. This other polygonal groove 70 can be an internal hexagonal blind hole groove (or a blind hole groove of other shapes). In a preferred embodiment, the outer diameter of the gear segment 71 is larger than the outer diameter of the screw segment 72.

[0053] In some implementations, such as Figures 6a-6b As shown, one end of the drive worm 6 may be provided with a polygonal groove 60, which may be an internal hexagonal blind hole groove, etc. The polygonal groove 60 is used to connect with an external drive tool 8, so that the external drive tool 8 can drive the drive worm 6 to rotate through the polygonal groove 60.

[0054] One end of the drive worm 6 has a profile adapted to the polygonal groove. When the polygonal groove 60 is an internal hexagonal blind hole groove, one end of the drive tool is externally hexagonal. The drive tool can be a drive rod, etc.

[0055] In some implementations, such as Figure 1 and Figure 9 As shown, there can be two drive worm gears 6, and the gear segment 71 of the hoisting component 7 is clamped between the two drive worm gears 6.

[0056] In the example above, the two drive worm gears 6 work together to achieve a self-locking function for the lifting component 7, thereby improving the stability of the lifting component 7.

[0057] In some implementations, such as Figure 1 As shown, the aforementioned hoisting assembly 1 may have a crossbeam 13, on which a mounting groove 130 may be provided, and both of the aforementioned drive worm gears 6 may be rotatably mounted in the mounting groove 130.

[0058] In the above example, the mounting slot 130 can limit the position of the two drive worm gears 6, and by setting the drive worm gears 6 inside the crossbeam 13, it is beneficial to make the overall structure more compact.

[0059] like Figures 7a-7bAs shown, the main structure of the crossbeam 13 is a long, narrow groove structure. Two through-holes 131 are provided on the sheet metal parts at both ends of the crossbeam 13, forming a symmetrical structure (a symmetrical structure when the slots face upwards). The through-holes 131 can be U-shaped cuts or circular openings, etc. Bolt through-holes 132 and fixing holes 133 are provided on the bottom end face of the crossbeam 13; the crossbeam 13 is fixed to the support beam 12 of the hoisting assembly 1 through the fixing holes 133. The diameter of the bolt through-hole 132 allows the screw section 72 of the hoisting component 7 to pass through, but not the gear section 71. In actual use, the slot of the mounting groove 130 can face downwards or upwards. A facing upward slot is a preferred embodiment because it allows the drive worm gear 6 to be placed inside the mounting groove 130 to form support and limit its movement (the crossbeam 13 in each figure is illustrated with the mounting groove 130 facing upwards as an example).

[0060] In some implementations, such as Figure 1 As shown, the number of the aforementioned lifting components 7 can be two or more, and each lifting component 7 cooperates to form the aforementioned limiting structure.

[0061] In the above example, if only a single lifting component 7 lifts the fan assembly 2, the lifting component 7 may easily cause the fan assembly 2 to rotate when it rotates, resulting in the failure of the lifting and lowering movement of the fan assembly 2. However, the cooperation of two or more lifting components 7 can prevent the fan assembly 2 from rotating, thereby creating a limit on the fan assembly 2.

[0062] In a specific application example, such as Figure 1 As shown, the number of the aforementioned lifting components 7 can be two, with the two lifting components 7 spaced apart between the two drive worm gears 6.

[0063] like Figures 6a-6b As shown, the drive worm 6 may include small-diameter smooth rod sections 63 at both ends and a large-diameter smooth rod section 62 in the middle. A worm section 61 is provided between the large-diameter smooth rod section 62 and the small-diameter smooth rod section 63. The drive worm 6 meshes with the gear section 71 of the hoisting component 7 through the worm section 61. Figure 6aThe diagram shows that the drive worm 6 has two worm segments 61, one on the left and one on the right. In reality, the large-diameter smooth section 62 between these two worm segments 61 can be omitted, allowing the two worm segments 61 to be connected together. This results in the drive worm 6 having a structure of small-diameter smooth sections 63 at both ends and a middle worm segment 61. At each end face of the drive worm 6, a polygonal groove 60 is centrally located along its central axis. This polygonal groove 60 can be an internal hexagonal blind hole groove, or it can be a blind hole of other shapes. The internal hexagonal blind hole groove is used to connect an external drive tool (such as a matching external hexagonal drive rod) to rotate the drive worm 6. The drive worm 6 then transmits this rotational motion to the lifting component 7, creating a rotational motion. The rotation of the lifting component 7, threadedly connected to the fan assembly 2, forms a threaded joint motion, causing the fan assembly 2 to move up and down relative to the lifting component 7, thereby driving the fan assembly 2 to move up and down.

[0064] In some embodiments, the aforementioned hoisting structure further includes a locking structure, which is used to lock the wind turbine assembly 2 to the hoisting assembly 1 when the wind turbine assembly 2 is raised to the first position or lowered to the second position, so as to improve the stability of the wind turbine assembly 2.

[0065] In some implementations, such as Figure 1-4b As shown, this utility model also provides a fan settling device, which may include the aforementioned fan assembly 2 and any of the aforementioned hoisting structures. Because the fan settling device uses the aforementioned hoisting structure, and because the hoisting component 7 suspends the fan assembly 2, a top suspension structure for the fan assembly 2 can be formed. This reduces the load on the base 11 from the fan assembly 2, solving the problem in the prior art where fixing the fan assembly 2 only to the cabinet base 11 results in excessive load on the sheet metal parts of the base 11, thereby improving the reliability of the fan assembly 2 during long-distance transportation and operation.

[0066] In some implementations, such as Figure 1 As shown, the aforementioned fan assembly 2 may include a fan 22, a guide ring 23, a base plate 21, and a first fixing post 31. The guide ring 23 is located at the upper end of the fan 22, and the base plate 21 is located at the lower end of the fan 22. The first fixing post 31 is used to connect the guide ring 23 and the base plate 21 to improve the stability of the connection between the fan 22, the guide ring 23, and the base plate 21. The first fixing post 31 may be provided with a first threaded hole 310, through which the fan assembly 2 is threadedly connected to the aforementioned lifting component 7.

[0067] In the above example, the first fixing column 31 has a dual function: on the one hand, it can fix the guide ring 23 and the base plate 21; on the other hand, it also serves as the connecting part of the fan assembly 2 and connects it to the aforementioned hoisting component 7.

[0068] The first threaded hole 310 can extend from one end of the first fixed post 31 to the other end.

[0069] In some embodiments, the aforementioned fan 22 may be a centrifugal fan.

[0070] In some embodiments, when the hoisting structure further includes a locking structure, and the locking structure is used to lock the fan assembly 2 onto the hoisting assembly 1 when the fan assembly 2 is raised to the first position or lowered to the second position, the aforementioned hoisting assembly 1 may have a base 11, which has a moving opening 110 for the fan assembly 2 to pass through. For example... Figure 1-1b As shown, when the fan assembly 2 rises to the first position, the base plate 21 is located above the moving port 110, and the fan assembly 2 is locked to the base 11 by the locking structure through the base plate 21. Figures 4a-4b As shown, when the fan assembly 2 descends to the second position, the base plate 21 is located below the moving port 110, the guide ring 23 overlaps the upper end of the moving port 110, and the fan assembly 2 is locked to the base 11 by the locking structure through the guide ring 23.

[0071] In the above example, on the one hand, the base 11 can provide support for the fan assembly 2, and on the other hand, the fan assembly 2 is also suspended on the lifting component 7. In this way, the base 11 and the lifting component 7 can form a double support for the fan assembly 2, thereby solving the problem that the sheet metal parts of the base 11 are too heavy due to the fan assembly 2 being fixed only on the base 11. This is beneficial to the long-distance transportation and reliable operation of the fan assembly 2.

[0072] In some implementations, such as Figure 1-4b As shown, a movable support plate 4 may be provided on the aforementioned base plate 21, which can extend or retract from the base plate 21. When the fan assembly 2 rises to the first position, the movable support plate 4 can extend from the base plate 21 and overlap the upper end of the moving opening 110, allowing the base plate 21 to be locked to the base 11 by the locking structure via the movable support plate 4. When the fan assembly 2 rises to the first position, the movable support plate 4 can also retract from the base plate 21, allowing the base plate 21 to pass through the moving opening 110.

[0073] In the above example, compared with the prior art solution of disassembling the support plate, the present invention designs the support plate as a movable support plate 4, which is set on the base plate 21 and moves with the base plate 21. It does not need to be removed from the base plate 21, so the movable support plate 4 does not need to be specially placed and is not easy to be lost.

[0074] To enable the movable support plate 4 to function as a movable support plate, in some embodiments, the aforementioned movable support plate 4 can be sleeved on the aforementioned first fixed post 31 and threadedly connected to the first fixed post 31. The movable support plate 4 can rotate relative to the first fixed post 31 to extend or retract the base plate 21 by rotation.

[0075] To achieve the function of the aforementioned locking structure, in some embodiments, the aforementioned locking structure can be a threaded fastener 5, such as a bolt. The aforementioned base 11 is provided with a second threaded hole 15 for threaded connection with the threaded fastener 5. The aforementioned movable support plate 4 and guide ring 23 are both provided with fastener through holes 41 for the threaded fastener 5 to pass through.

[0076] Among them, such as Figure 1-1b As shown, when the hoisting component 7 lifts the fan assembly 2 to the first position, the threaded fastener 5 passes through the fastener through hole 41 on the movable support plate 4 and is threaded into the second threaded hole 15 to lock the fan assembly 2 onto the base 11. Figures 4a-4b As shown, when the hoisting component 7 lowers the fan assembly 2 to the second position, the threaded fastener 5 passes through the fastener through hole 41 on the guide ring 23 and is threadedly connected in the second threaded hole 15 to lock the fan assembly 2 onto the base 11.

[0077] like Figure 8 As shown, the movable support plate 4 is provided with a fastener through hole 41 and an internal thread hole 42. The end of the first fixed column 31 may be provided with an external thread section. The movable support plate 4 is sleeved on the external thread section of the first fixed column 31 through the internal thread hole 42, and the two are threadedly engaged.

[0078] In some implementations, such as Figure 2b As shown, the aforementioned fan assembly 2 may also include a second fixing post 32 for connecting the guide ring 23 and the base plate 21. The second fixing post 32 is provided with a wiring hole for the power cord 14 of the fan assembly 2 to pass through, which can save wiring space.

[0079] This utility model also provides an air conditioner, which may include any of the above-mentioned hoisting structures; or include any of the above-mentioned fan settling devices.

[0080] Among them, the air conditioner can be a data center air conditioner.

[0081] For ease of understanding, the overall structure of this utility model will be described below, and its working principle will be explained.

[0082] like Figure 9As shown in the assembly diagram of the drive worm 6, lifting component 7, and crossbeam 13, the gear segment 71 of the matching lifting component 7 is sandwiched between the two drive worms 6 on the left and right. The screw segment 72 of the lifting component 7 passes through the bolt through hole 132 of the crossbeam 13 from top to bottom. Because the outer diameter of the gear segment 71 of the lifting component 7 is larger than the diameter of the bolt through hole 132 of the crossbeam 13, the lifting component 7 can only rotate while suspended on the crossbeam 13. The two drive worms 6 are placed in the mounting groove 130 of the crossbeam 13 for limiting. The diameter of the small-diameter smooth rod segment 63 at both ends of the drive worm 6 is larger than the diameter of the through hole 131 at both ends of the crossbeam 13. The through hole 131 at both ends of the crossbeam 13 can be a U-shaped groove or a circular opening. The circumscribed circle diameter of the polygonal groove 60 on both ends of the drive worm 6, such as a hexagonal blind hole, is smaller than the diameter of the through hole 131 at both ends of the crossbeam 13. This allows external tools to pass continuously through the through hole on the support beam 12. Figure 9 Not shown in the image, please refer to the following: Figure 1-4b The crossbeam 13 passes through the opening 131 and enters the polygonal groove 60 on the end face of the drive worm 6 for matching use, and uses the force of an external tool to rotate the drive worm 6.

[0083] like Figures 1 to 4b The diagram shown is a structural schematic of the wind turbine settling device of this utility model and a schematic diagram of the lifting process, including a hoisting component 1, a wind turbine component 2 and several general hardware parts such as fixing bolts and locking nuts.

[0084] like Figures 1 to 4b As shown, the hoisting assembly 1 includes a base 11, columns 9, support beams 12, crossbeams 13, a drive worm gear 6, and hoisting components 7. The number of support beams 12 can be four, including two opposing first support beams 121 and two opposing second support beams 122, which are connected to the four columns 9 on the same horizontal plane. The crossbeams 13 are connected to either the opposing first support beams 121 or the opposing second support beams 122 (using connection to the first support beams 121 as an example). The base 11 has a movable port 110 that matches the fan assembly 2, allowing the fan assembly 2 to move freely up and down on the movable port 110 (the outer edge sheet metal of the guide ring 23 at the top of the fan assembly 2 cannot pass through the movable port 110). The periphery of the movable port 110 has a uniformly arranged annular array of second threaded holes 15.

[0085] The fan assembly 2 includes a base plate 21, a fan 22, a fixed column 3, a movable support plate 4, a guide ring 23, a lock nut, a lock bolt 10, and fixing bolts, etc. The fan 22 can be a centrifugal fan, etc. The base plate 21 has various through holes and internal threaded holes, especially through holes for the fan motor and internal threaded holes matching the external threaded section of the fixed column.

[0086] The fixing post 3 is used to connect the base plate 21 and the guide ring 23. Both ends of the fixing post 3 have external threads. The diameter of the middle straight rod portion of the fixing post 3 is larger than the diameter of the corresponding through hole on the guide ring 23, while the diameter of the corresponding through hole on the guide ring 23 is larger than the diameter of the external thread section at the end of the fixing post 3. After the external thread section at the upper end of the fixing post 3 passes through the guide ring 23, it is fixed by a lock nut and / or a locking nut 10, thus fixing the guide ring 23 between the middle straight rod portion of the fixing post 3 and the lock nut and / or locking nut 10.

[0087] The external threaded section at the lower end of the fixed column 3 extends out of the base plate 21 and mates with the internal threaded hole 42 on the movable support plate 4 to form a threaded connection. The aforementioned movable support plate 4 is installed on the external threaded section at the lower part of the fixed column 3. The movable support plate 4 can rotate freely around the fixed column 3; that is, after rotating around the fixed column 3, the fastener through hole 41 on the movable support plate 4 can be located either on the lower inner side of the base plate 21 or on the lower outer side of the base plate 21. When the movable support plate 4 rotates around the fixed column 3 to the lower inner side of the base plate 21, the entire movable support plate 4 is located below the base plate 21, with no part of the side of the base plate 21 exposed. This ensures that the fan assembly 2 can move freely up and down on the movable port 110 without obstruction. Figure 1 and Figure 4b As shown, the movable support plate 4 extends beyond the outer edge of the base plate 21 and rests on the base 11. The fan assembly 2 is fixed to the base 11 by using threaded fasteners 5 passing through the fastener holes 41 of the movable support plate 4. Conversely, the threaded fasteners 5 can be removed and the movable support plate 4 can be rotated to the bottom inner side of the base plate 21 (e.g., ...). Figure 2a and Figure 2b (As shown).

[0088] The aforementioned fixing posts 3 are in the form of two or more, with some fixing posts 3 serving as the first fixing posts 31 and others serving as the second fixing posts 32. The main body of each fixing post 3 has a hollow internal thread structure, allowing the first fixing post 31 to form the aforementioned first threaded hole 310 internally, and the second fixing post 32 to form the aforementioned wiring hole internally. Each end of the fixing post 3 also has an external thread section 72 that mates with the internal threaded hole 42 of the locking nut and / or the locking nut and / or the movable support plate 4. The hollow internal thread forms the first threaded hole 310 of the first fixing post 31, which mates with the threaded section 72 of the lifting component 7 to form a threaded pair movement. The outer edge of the guide ring 23 has fastener through holes 41 on its sheet metal part, which mate with the second threaded holes 15 arranged in a uniform annular array around the moving port 110 of the base 11.

[0089] The fan 22 of the fan assembly 2 is fixed on the base plate 21. The external threaded section of one end of the fixing column 3 is threadedly connected to the internal threaded hole of the base plate 21 for fixation. Then, at the bottom of the base plate 21, the internal threaded hole 42 of the movable support plate 4 is threadedly connected to the external threaded section of the fixing column 3 again. The movable support plate 4 can then rotate 360 ​​degrees around the fixing column 3, allowing the movable support plate 4 to extend out of the outer edge of the base plate 21 or be retracted into the bottom of the base plate 21 (extending out of the outer edge of the base plate 21 is mainly used to support and fix the fan assembly 2 on the base 11, while retracting into the bottom of the base plate 21 allows the fan assembly 2 to move freely up and down at the movable port 110). The movable support plate 4 can be sleeved on the aforementioned first fixing column 31. The guide ring 23 is centrally fitted onto the top of the fan 22. The outer edge of the guide ring 23 has corresponding bolt holes for the threaded section at the other end of the fixing column 3 to pass through. Therefore, after the guide ring 23 is positioned, the threaded section at the top of the fixing column 3 will extend beyond the top of the guide ring 23. A lock nut and / or lock cap 10 are then used to thread-connect and fix the guide ring 23 to the fixing column 3. The outer diameter of the base plate 21 and the fan 22 is smaller than the diameter of the moving port 110, while the outer diameter of the outer edge of the guide ring 23 is larger than the diameter of the moving port 110, thus ensuring that the lower part of the fan assembly 2 can freely pass through the moving port 110.

[0090] like Figure 1 As shown in the figure, four fixing columns 3 are used as an example for illustration. There can also be six, eight, etc., but usually no fewer than four fixing columns 3 are used to ensure the stability of the fan assembly 2. Two fixing columns 3 located on the same horizontal diameter direction as the guide ring 23 serve as the aforementioned first fixing columns 31. The top of the first fixing column 31 is secured with a lock nut so that the screw section 72 of the lifting component 7 can pass through the first threaded hole 310 inside the first fixing column 31. Another fixing column 3 can be arbitrarily selected as the aforementioned second fixing column 32. The top of the second fixing column 32 is also secured with a lock nut so that the power cable 14 of the motor of the bottom fan 22 passes through the middle of the second fixing column 32 from bottom to top to reach the upper part of the unit. The gap between the power cable 14 and the cable routing hole can be sealed with sealant or similar materials. The top of the remaining fixed columns 3 is fixed with locking nuts 10. The nuts can seal the internal threaded holes of the fixed columns 3 to prevent the high-pressure air at the outlet of the fan 22 from flowing upward from the internal threaded holes of the fixed columns 3 back to the inlet of the fan 22, thus avoiding air leakage.

[0091] like Figure 1 and Figure 1bAs shown, after the movable support plate 4 at the bottom of the fan assembly 2 is rotated, its fastener through hole 41 is located at the lower outer part of the base plate 21 (i.e., the movable support plate 4 is rotated out). The fan assembly 2 is moved into the moving port 110 on the aligning base 11 of the hoisting assembly 1 and placed on the base 11. The position is adjusted so that the fastener through hole 41 of the movable support plate 4 of the fan assembly 2 is aligned with the second threaded hole 15 on the base 11. The movable support plate 4 of the fan assembly 2 and the base 11 of the hoisting assembly 1 are connected by threaded fasteners 5, such as fixing bolts. The hoisting component 7 passes through the bolt through hole 132 of the crossbeam 13 from top to bottom and is manually or / electrically rotated so that the hoisting component 7 enters the first threaded hole 310 of the first fixing column 31 at the bottom until the outer gear section 71 of the hoisting component 7 contacts the bottom of the crossbeam 13. The two drive worm gears 6 are respectively rotated and placed into the mounting groove 130 of the crossbeam 13 and mesh with the gear section 71 of the hoisting component 7. The fixed assembly in the factory state is thus completed.

[0092] As described above, the bottom of the fan assembly 2 is fixed to the base 11 with threaded fasteners 5, and the top of the fan assembly 2 is suspended from the crossbeam 13 by the lifting device 7. Therefore, the factory-fixed state of the fan assembly 2 is more reliable and effective (bottom fixed + top suspended), which can reduce the impact force of the fan assembly 2 on the base 11 during transportation. In contrast, the traditional fan assembly 2 is only fixed to the base 11 (bottom fixed), which places higher load requirements on the base 11.

[0093] like Figure 2a and Figure 2b As shown, before the wind turbine assembly 2 is lowered into the installation site or laboratory for testing, the factory-fixed condition needs to be removed:

[0094] 1) Remove the threaded fasteners 5 between the movable support plate 4 of the fan assembly 2 and the base 11 of the hoisting assembly 1;

[0095] 2) Use an external tool, such as a drive rod, to apply force to rotate the drive worm gear 6, which will cause the lifting component 7 to rotate, so that the fan assembly 2 moves slightly upward and is fixed to prevent the fan assembly 2 from falling.

[0096] 3) Rotate the movable support plate 4 at the bottom of the fan assembly 2 so that it rotates to the lower inner side of the bottom plate 21 of the fan assembly 2, so as to prevent the movable support plate 4 from obstructing the lifting and lowering movement of the fan assembly 2 at the moving port 110.

[0097] like Figure 3a and Figure 3b As shown, an external tool, such as a drive rod, is used to rotate the drive worm gear 6, which in turn rotates the lifting component 7, thereby causing the wind turbine assembly 2 to move up and down. The rotation of the drive rod continues until the guide ring 23 at the top of the wind turbine assembly 2 rests on the base 11 of the lifting assembly 1, as shown. Figure 4a and Figure 4bAs shown, the sinking action of the fan assembly 2 is complete. At this time, the fastener through holes 41 on the sheet metal part of the outer edge of the guide ring 23 should be aligned with the second threaded holes 15 on the base 11 one by one. The fan assembly 2 is then fixed to the second threaded holes 15 on the base 11 of the hoisting assembly 1 using threaded fasteners 5, such as fixing bolts, to complete the second fixing state. After the fan assembly 2 sinks, its top is still suspended from the crossbeam 13 by the hoisting component 7, which can reduce the load of the fan assembly 2 on the base 11, improve the reliability of the unit, require fewer parts, and is simple, labor-saving, and safe to operate.

[0098] The above steps are reversed (of course, the order of some steps can be adjusted or even omitted) to perform the rising operation of fan assembly 2, which will not be elaborated here.

[0099] In this invention, a drive worm gear 6 on the hoisting assembly 1 works in conjunction with a hoisting component 7 to hoist and lift the fan assembly 2. Two drive worm gears 6 arranged on the same horizontal plane clamp the hoisting component 7, which is suspended from the crossbeam 13. The drive worm gears 6 are placed inside the mounting groove 130 of the crossbeam 13 for limiting their movement. An external driving tool 8, such as a drive rod, rotates the drive worm gear 6, thereby causing the hoisting component 7 to rotate. The screw section 72 of the hoisting component 7 forms a threaded joint with the first threaded hole 310 inside the first fixed column 31 on the fan assembly 2. Since the hoisting component 7, suspended on the crossbeam 13, can only rotate, the fixed column 3 moves up and down relative to the hoisting component 7, thus driving the entire fan assembly 2 to achieve a lifting effect. The fan assembly 2 moves up and down within the moving port 110 on the base 11, with the upper and lower limits achieved by the outer edge of the guide ring 23 at the top of the fan assembly 2.

[0100] The technical solution of this utility model solves the problems of complex lifting structure, excessive space required, difficulty in lifting and inconvenient maintenance of the existing horizontally fixed centrifugal fan assembly 2. In particular, it solves the problem that the existing centrifugal fan assembly 2 is only fixed on the base 11, resulting in excessive load on the sheet metal parts of the base 11.

[0101] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

The above description is only a preferred embodiment of this utility model.
