[0042] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] A diesel locomotive is a vehicle used to haul railway trains. It includes a cooling system that cools the locomotive's engine using circulating coolant. The cooling system consists of a radiator and cooling fans for cooling the radiator, assembled in a cooling chamber. During the production or maintenance of the locomotive's cooling system, cooling fans need to be installed in the cooling chamber. The cooling chamber has vertically arranged cylindrical air ducts. Each cooling fan has a fan mount, a hydrostatic motor mounted on the fan mount, and fan blades connected to the shaft of the hydrostatic motor. The fan mount is located below the top of the air duct and needs to be coaxial with the air duct. When installing a cooling fan in the locomotive's cooling chamber, the fan mount must be installed in the air duct. To install the fan mount, it must first be positioned in the air duct, and then fixed in the air duct using a connecting structure.

[0045] For example, the cooling chamber is a steel structure.

[0046] For example, the fan base is connected to the air duct by multiple tie rods, which are spaced apart along the circumference of the fan base. When the tie rods deform, the fan base will shift, which can easily cause wear between the fan blades and the inner wall of the air duct. In this case, the fan base needs to be removed from the air duct and repositioned and reassembled.

[0047] Furthermore, if the fan mount is not positioned accurately when assembling in the air duct, it can still easily cause contact wear between the fan blades and the inner wall of the air duct.

[0048] In the prior art, multiple people support the fan mount to maintain it at the corresponding height and radial position in the air duct, thereby positioning the fan mount within the air duct.

[0049] However, the aforementioned existing technologies suffer from low positioning efficiency and unstable positioning.

[0050] However, the aforementioned existing technologies suffer from low positioning efficiency and unstable positioning. For example, taking the height positioning of the fan base as an example, on the one hand, manually determining the height of the fan base relative to the air duct is time-consuming and laborious; on the other hand, when a person supports the fan base, their arm cannot maintain a fixed position for an extended period, and even slight shaking can cause the fan base's position to change, affecting the stability of the positioning. For example, when fixing the fan base using a connecting structure, one end of the connecting structure is welded to the inner wall of the air duct, and the other end is welded to the fan base. If the fan base positioning is unstable during the spot welding process, it will ultimately result in inaccurate fan base positioning, thus causing inaccurate fan base positioning.

[0051] To address the aforementioned issues, this application provides a fan mount positioning device to improve the positioning efficiency and stability of the fan mount in the air duct.

[0052] The fan mount positioning device provided in this application, during use, uses multiple fasteners to position and fix the fan mount relative to the mounting frame in both radial and axial positions. A lifting assembly can be connected to hoisting equipment to lift the mounting frame above the air duct. Multiple positioning rods are supported at the top of the air duct to position the height and parallelism of the fan mount fixed to the mounting frame relative to the air duct. The support of the positioning rods replaces manual support, reducing labor intensity and ensuring positioning stability. The positioning reference facilitates determining the radial position of the mounting frame relative to the air duct, enabling coaxial positioning of the fan mount fixed to the mounting frame relative to the air duct, thus improving positioning efficiency and accuracy. This positioning work eliminates the need for auxiliary tools such as measuring tapes. During the positioning of the positioning rods relative to the air duct, the fan mount positioning device can be lifted using hoisting equipment, allowing the positioning rods to move upwards a small distance away from the upper surface of the air duct. This facilitates moving or rotating the hoisted fan mount positioning device for alignment and adjustment, further improving positioning efficiency.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0054] Reference Figure 6 As shown, the fan mount positioning device of this application is used for assembling and positioning the fan mount 1 in the air duct 10.

[0055] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6As shown in the figure, the fan mount positioning device provided in this application embodiment includes: a hoisting assembly 100, a mounting bracket 200, a positioning rod 300, and a fixing member 400.

[0056] The mounting frame 200 includes a connecting portion 210 and a mounting portion 220, with the connecting portion 210 connected to the lifting assembly 100. It should be noted that the lifting assembly 100 is used to connect to lifting equipment to facilitate the lifting of the fan seat positioning device by the lifting equipment. Exemplarily, the lifting assembly 100 and the connecting portion 210 can be fixedly connected, for example, by welding. Alternatively, exemplarily, the lifting assembly 100 and the connecting portion 210 can be detachably connected. Exemplarily, the lifting assembly 100 can be at least partially rotatable, this rotation facilitating the rotation of the mounting frame 200 relative to the ropes used by the lifting equipment to connect the lifting assembly 100, thereby adjusting the radial orientation of the mounting frame 200.

[0057] The mounting portion 220 is connected to the connecting portion 210, and there are multiple mounting portions 220 arranged circumferentially along the air duct 10. For example, the mounting portion 220 and the connecting portion 210 can be an integral structure. Alternatively, for example, the mounting portion 220 and the connecting portion 210 can be detachably connected, such as by bolts and corresponding connecting plates. For example, there can be 3, 4, 5, or more mounting portions 220. The embodiments of this application are mainly described with 4 mounting portions 220. When there are 4 mounting portions 220, the mounting portions 220 can be in a cross shape.

[0058] Multiple positioning rods 300 are provided on the corresponding mounting portions 220, corresponding to the mounting portions 220. For example, the positioning rods 300 and the mounting portions 220 can be welded together. Alternatively, for example, the positioning rods 300 and the mounting portions 220 can be detachably connected by multiple bolts to facilitate replacement of positioning rods 300 of different lengths as needed.

[0059] The bottom surface of the positioning rod 300 is used to abut against the upper end surface of the air duct 10. Exemplarily, the positioning rod 300 can be a channel steel; it is understood that the cross-section of the channel steel is approximately "[" shaped, and the channel steel includes two channel steel legs, the ends of which can be used as the bottom surface of the positioning rod 300. Alternatively, exemplarily, the positioning rod 300 can be a square steel; it is understood that the cross-section of the square steel is approximately rectangular. The embodiments of this application are mainly described using a channel steel as the positioning rod 300.

[0060] The positioning rod 300 is provided with a positioning reference 300a. The positioning reference 300a is used to position the corresponding position of the positioning rod 300 radially at the end of the air duct 10.

[0061] Reference Figure 1As shown, in some embodiments, the positioning reference 300a can be a scale line. When the positioning reference 300a is a scale line, the corresponding position of the positioning rod 300 at the end of the air duct 10 can be radially positioned by aligning the scale line with a corresponding reference position on the air duct 10 (e.g., the inner or outer wall of the air duct 10). When the positioning reference 300a is a scale line, the setting position of the scale line on the corresponding positioning rod 300 should be easy to observe.

[0062] Reference Figure 4 and Figure 6 As shown, in some embodiments, the positioning reference 300a may be a cylinder welded to the positioning rod 300. The corresponding position of the positioning rod 300 is radially positioned at the end of the air duct 10 by pressing the side wall of the cylinder against the inner or outer wall of the air duct 10.

[0063] Reference Figure 5 and Figure 6 As shown, in some embodiments, the positioning reference 300a can be a cylinder inserted into the positioning rod 300 to facilitate disassembly of the positioning reference 300a from the positioning rod 300. Specifically, the positioning rod 300 has a hole with a diameter approximately equal to that of the cylinder, and the top of the cylinder has a stop, into which the cylinder is inserted. Positioning is achieved by the side wall of the cylinder abutting against the inner or outer wall of the air duct 10.

[0064] Multiple fasteners 400 are provided, corresponding to the positioning rods 300. The fasteners 400 are used to connect the fan base 1. When the fasteners 400 are connected to the fan base 1, the fan base 1 and the mounting bracket 200 are coaxial. It should be noted that the fasteners 400 are used to limit the distance between the fan base 1 and the positioning rods 300, so that when the positioning rods 300 are supported at the end of the air duct 10, the distance between the fan base 1 and the upper end of the air duct 10 is limited.

[0065] For example, the fastener 400 can be welded to the corresponding positioning rod 300, and the fan seat 1 is detachably connected to the fastener 400. Specifically, the fan seat 1 has holes for connecting the base of the hydrostatic motor. Some of these holes in the fan seat 1 are smooth holes, while others are threaded holes. The fan seat 1 can be detachably connected to the fastener 400 by using these holes and a combination of bolts and nuts that mate with them, or by using bolts alone. It is understood that the position of the fastener 400 on the positioning rod 300 is adapted to the distribution of the holes on the fan seat 1 for connecting the hydrostatic motor. Thus, by utilizing the holes on the fan seat 1 for connecting the hydrostatic motor to connect the fastener, it is advantageous to quickly position the fan seat 1 axially relative to the mounting bracket 200, and this positioning process does not require the use of measuring tools such as a tape measure, thereby improving positioning efficiency and accuracy.

[0066] Alternatively, for example, the fixing member 400 and the corresponding positioning rod 300 can be detachably connected. Further, the fixing member 400 can be a screw, and the positioning rod 300 has a threaded hole for engaging with the screw. The screw is detachably connected to the fixing member 400 through engagement with the threaded hole. When the fixing member 400 is a screw, it facilitates disassembly from the positioning rod 300; furthermore, the screw allows for adjustment of the length of its lower end extending beyond the positioning rod 300, which can be used to adjust the distance between the fan seat 1 and the top of the air duct 10.

[0067] Alternatively, for example, the fastener 400 can be a double-ended screw, which, understandably, has threads at both ends. The positioning rod 300 has a hole for the double-ended screw to pass through, with one end of the double-ended screw passing through the positioning rod 300 and protruding upwards. A nut is threaded onto the protruding end of the double-ended screw to prevent it from falling downwards from the positioning rod 300. The fan seat 1 has a hole for the double-ended screw to pass through, with the double-ended screw passing through this hole and protruding downwards from the fan seat. Another nut is threaded onto this end of the double-ended screw to prevent the fan seat 1 from falling downwards from the double-ended screw; alternatively, the lower end of the double-ended screw can be threaded onto the fan seat 1.

[0068] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the fan mount positioning device provided in this application, during use, uses multiple fasteners 400 to position and fix the fan mount 1 relative to the mounting frame 200 in both radial and axial positions. A lifting device can be connected via the lifting assembly 100 to hoist the mounting frame 200 above the air duct 10. Multiple positioning rods 300 are supported at the top of the air duct 10 to position the height and parallelism of the fan mount 1 fixed to the mounting frame 200 relative to the air duct 10. The support of the positioning rods 300 replaces manual support, reducing workload and ensuring positioning stability. The positioning reference 300a facilitates determining the radial position of the mounting frame 200 relative to the air duct 10, enabling coaxial positioning of the fan mount 1 fixed to the mounting frame 200 relative to the air duct 10, thus improving positioning efficiency and accuracy. Furthermore, this positioning work eliminates the need for auxiliary tools such as measuring tapes. During the process of positioning the positioning rod 300 relative to the air duct 10, the fan seat positioning device can be lifted by a lifting device so that the positioning rod 300 moves upward a small distance away from the upper end face of the air duct 10, so as to facilitate the movement or rotation of the fan seat positioning device for alignment and adjustment, thereby improving positioning efficiency.

[0069] For example, a method for installing a fan mount using the fan mount positioning device provided in this application may include the following steps:

[0070] S100: Connect the fan mount 1 to the fastener 400 to position the fan mount 1 relative to the fan mount positioning device;

[0071] S200: Connect the hoisting assembly 100 via the lifting equipment to hoist the fan base 1 above the air duct 10, and position the positioning rod 300 radially relative to the air duct 10;

[0072] S300: The fan base positioning device is lowered so that each positioning rod 300 is supported on the upper surface of the air duct 10, and the levelness of the fan base 1 is checked.

[0073] S400: A connecting structure is provided between the fan mount 1 and the air duct 10 to fix the fan mount 1 in the air duct 10.

[0074] Reference Figure 12 As shown, exemplarily, the connection structure can be multiple web plates 11, with one end of each web plate 11 welded to the inner wall of the air duct 10 and the other end welded to the fan base 1. Exemplarily, the web plates 11 include eight plates a, b, c, d, e, f, g, and h, evenly spaced along the circumference of the fan base 1. During welding, they can be welded and fixed in the order of a, e, c, g, h, d, b, and f to ensure the symmetry of the welding operation as much as possible, thereby reducing or even avoiding thermal deformation of the fan base 1 or the air duct 10.

[0075] After the connecting structure fixes the fan base 1 in the air duct 10, the connection between the fan base 1 and each of the fixing parts 400 is removed.

[0076] Reference Figure 1 and Figure 3 As shown, in some embodiments, the mounting portion 220 and the positioning rod 300 are nested together. This nesting arrangement allows the mounting portion 220 to limit the positioning rod 300, helping to maintain the stability of its orientation. Furthermore, it facilitates a detachable connection between the mounting portion 220 and the positioning rod 300. Specifically, fasteners such as bolts can be provided between the mounting portion 220 and the positioning rod 300 to fix the positioning rod 300 in the nested position and facilitate disassembly. For example, when the positioning rod 300 is a channel steel, the mounting portion 220 is a channel steel for nesting a portion of the positioning rod 300. For example, when the positioning rod 300 is a square steel, the mounting portion 220 has a square hole for nesting a portion of the positioning rod 300.

[0077] Reference Figure 1 and Figure 3As shown, in some embodiments, the position of the positioning rod 300 relative to the mounting portion 220 along the radial direction of the air duct 10 is adjustable. This facilitates adjustment of the radial extension length of the positioning rod 300 to suit the operating conditions of air ducts 10 with different diameters. It should be noted that when the position of the positioning rod 300 relative to the mounting portion 220 along the radial direction of the air duct 10 is adjustable, the nesting fit between the mounting portion 220 and the positioning rod 300 can be a sliding nesting. For example, when both the positioning rod 300 and the mounting portion 220 are channel steel, the radial position of the positioning rod 300 is adjusted by sliding the positioning rod 300 relative to the mounting portion 220. For example, when the positioning rod 300 is square steel, the radial position of the positioning rod 300 is adjusted by positioning the positioning rod 300 relative to the corresponding square hole.

[0078] Reference Figure 1 , Figure 9 and Figure 10 As shown, in some embodiments, the mounting portion 220 defines a mounting groove 221 extending radially along the air duct 10. A positioning rod 300 is disposed within the mounting groove 221, and the groove wall of the mounting groove 221 has multiple positioning structures spaced radially along the air duct 10. These positioning structures are used to position the positioning rod 300. For example, the positioning structure can be a bolt, a pin, or a protrusion. When the positioning structure is a bolt or pin, the corresponding position of the positioning rod 300 has a hole for engaging with the bolt or pin. When the positioning structure is a bolt, the bolt also serves to fasten the mounting portion 220 and the corresponding positioning rod 300. When the positioning structure is a protrusion, the corresponding position of the positioning rod 300 has a slot for engaging with the protrusion. Thus, the mounting groove 221 facilitates the radial guidance of the corresponding positioning rod 300 along the air duct 10, and the positioning structures limit the radial length of the positioning rod 300 within the air duct 10.

[0079] Reference Figure 1 , Figure 9 and Figure 10As shown, in some embodiments, the groove wall of the mounting groove 221 is provided with a plurality of positioning holes 221a arranged radially at intervals along the air duct 10. For example, the number of positioning holes 221a can be 2, 3, 4, 5 or more. The positioning rod 300 is provided with positioning mating holes 310, and the number of positioning mating holes 310 on the same positioning rod 300 can be one or more. The positioning rod 300 and the mounting part 220 are positioned by a positioning pin 221b passing through the positioning mating hole 310 and any one of the positioning holes 221a, and the positioning pin 221b constitutes a positioning structure. For example, one end of the positioning pin 221b can have a stop, and the other end of the positioning pin 221b can be threaded with a nut to fasten the positioning pin 221b to the mounting part 220 by the stop and the nut to prevent the positioning pin 221b from falling off. Alternatively, for example, one end of the positioning pin 221b may have a stop, and the other end of the positioning pin 221b may have a stop inserted radially along the positioning pin 221b to prevent the positioning pin 221b from falling off the mounting part 220 by means of the stop and the stop.

[0080] Thus, the mounting part 220 and the positioning rod 300 are slidably nested together, and their radial positions are fixed through the positioning hole 221a, the positioning mating hole 310, and the positioning pin 221b. The radial extension length of the positioning rod 300 can be easily adjusted by the engagement of the positioning pin 221b with the corresponding positioning mating hole 310 and positioning hole 221a to suit the operational needs of air ducts 10 with different diameters. It should be noted that when there are multiple sets of engagements of the positioning pin 221b, the positioning mating hole 310, and the positioning hole 221a on the same positioning rod 300, it helps to improve the firmness of the positioning rod 300 on the mounting part 220.

[0081] Understandably, the operation requirements of ducts with different diameters can also be met by replacing the positioning rods 300 with different lengths. The positioning pin 221b also facilitates the replacement of positioning rods 300 with different lengths.

[0082] Reference Figure 9 As shown, in some embodiments, the mounting groove 221 has an opening 221c on one side along the axial direction of the air duct 10, and multiple mounting grooves 221 converge and connect at the connecting portion 210. In this way, the opening 221c can reduce the difficulty of nesting and disassembling the positioning rod 300 on the mounting portion 220, which facilitates the more convenient assembly and disassembly of the positioning rod 300.

[0083] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the lifting assembly 100 includes a lifting rod 110 and a lifting ring 120. The lifting rod 110 passes through the connecting portion 210 along the axial direction of the air duct 10. Exemplarily, the lifting rod 110 is cylindrical, and the connecting portion 210 has a hole with a diameter equivalent to that of the lifting rod 110 for insertion. By inserting the lifting rod 110 through the connecting portion 210, the lifting assembly 100 can be easily assembled and disassembled at the connecting portion 210, allowing it to be used with different connecting portions 210 and improving its interchangeability. Exemplarily, a detachable connecting pin or other limiting member can be provided on the portion of the lifting rod 110 that passes through the connecting portion 210 to prevent the lifting rod 110 from falling out of its insertion position. The lifting ring 120 is located at the end of the lifting rod 110 away from the mounting frame 200. It should be noted that the lifting ring 120 is used to connect the lifting hook of the lifting equipment or a rope connected to the lifting equipment.

[0084] Reference Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, the lifting assembly 100 includes a support plate 130. The support plate 130 is located at the end of the lifting rod 110 away from the lifting ring 120, and is situated on the side of the positioning rod 300 facing the opening 221c. The support plate 130 and the positioning rod 300 abut against each other along the axial direction of the air duct 10. Exemplarily, the support plate 130 can be detachably connected to the positioning rod 300 by fasteners. By providing the support plate 130, when the lifting rod 110 is subjected to an upward lifting force, the support plate 130 is also subjected to an upward lifting force. This force helps to firmly press the support plate 130 against the positioning rod 300, preventing the positioning rod 300 from moving out of the opening 221c. This helps to maintain the stability of the installation position of each positioning rod 300 during the lifting of the fan seat positioning device.

[0085] Reference Figure 1 , Figure 3 , Figure 7 and Figure 8As shown, in some embodiments, a plurality of limiting structures 131 are provided around the tray 130. The limiting structures 131 are engaged at the corners of the connection between two adjacent mounting portions 220, and are located outside the mounting groove 221. Thus, the limiting structures 131 can limit the positioning rod 300 in the circumferential direction of the air duct 10 to maintain the stability of the positioning rod 300's orientation and also provide a certain degree of reinforcement. For example, when the positioning rod 300 is channel steel or square steel, the limiting structure 131 is a right-angled external angle. For example, the bottom of the limiting structure 131 is welded to the tray 130 to form a firm connection with the tray 130. For example, the limiting structure 131 is a right-angled steel plate welded to the tray 130. The side of the positioning rod 300 abuts against the side wall of the limiting structure 131 opposite to that side.

[0086] Reference Figure 1 , Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, the lifting assembly 100 further includes a mounting sleeve 140. The mounting sleeve 140 is sleeved on the lifting rod 110 and fixedly connected to the lifting rod 110. For example, the support plate 130 is fixed to the lifting rod 110 (e.g., welded). The lifting rod 110 has a first pin hole 111, and the mounting sleeve 140 has a second pin hole 142 for alignment with the first pin hole 111. A pin is provided between the first pin hole 111 and the second pin hole 142 to fix the mounting sleeve 140 to the lifting rod 110. Thus, by providing the mounting sleeve 140, a detachable connection is easily formed with the lifting rod 110, facilitating the disassembly of the lifting assembly 100. When it is necessary to disassemble the lifting assembly 100, the mounting sleeve 140 is removed from the lifting rod 110, and the lifting rod 110 is pulled downward out of its through-position on the mounting frame 200.

[0087] The mounting sleeve 140 defines a mounting cavity 141, with a through hole 141a at the end opposite to the lifting ring 120. The lifting ring 120 includes a rod 121 and a hook 122. The rod 121 passes through the through hole 141a into the mounting cavity 141, allowing it to rotate relative to the mounting sleeve 140 within the cavity. Thus, when the fan seat positioning device is lifted a certain distance away from the duct 10 by a lifting device, and the positioning rod 300 is rotated circumferentially relative to the duct 10, the rotation of the rod 121 relative to the mounting sleeve 140 reduces the difficulty of rotating the positioning rod 300, facilitating quick adjustment of its position. The hook 122 connects to the rod 121 and is used to connect to the lifting device. For example, the hook 122 may be annular; or, it may be an open loop shape.

[0088] Reference Figure 1 , Figure 3 , Figure 7 and Figure 8 In some embodiments, the lifting assembly 100 further includes a bearing member 150. The bearing member 150 is disposed within the mounting cavity 141 and has an inner bearing ring 151 and an outer bearing ring 152. The outer bearing ring 152 mates with the mounting sleeve 140. Exemplarily, the outer bearing ring 152 and the mounting sleeve 140 can be fixedly connected, which can be achieved by welding or fasteners. Alternatively, exemplaryly, the top of the sleeve 140 may have a retaining ring for confining the outer bearing ring 152 within the mounting cavity 141 to prevent the bearing member 150 from falling off. A rod portion 121 passes through the inner bearing ring 151. Exemplarily, the rod portion 121 and the inner bearing ring 151 can be fixedly connected, which can be achieved by welding or fasteners. Alternatively, for example, the bottom of the rod 121 is provided with a stop for restricting the lower end of the rod 121 below the bearing inner ring 151, so as to prevent the lower end of the rod 121 from falling upward out of the bearing inner ring 151.

[0089] Thus, the bearing component 150 facilitates smoother rotation of the rod 121 relative to the mounting sleeve 140. This further reduces the workload of adjusting the rotation of the positioning rod 300 and improves work efficiency.

[0090] Reference Figure 1 , Figure 3 , Figure 6 ,and Figure 11 As shown, in some embodiments, the positioning rod 300 is provided with a fixing hole 320, and the fixing member 400 passes through the fixing hole 320. For example, the top of the fixing member 400 may have a stop, the bottom of which abuts against the upper surface of the positioning rod 300, and the bottom end of the fixing member 400 is fixed to the fan seat 1 to position the distance between the fan seat 1 and the upper surface of the air duct 10. For example, the fixing method between the bottom end of the fixing member 400 and the fan seat 1 can be temporary fixing by spot welding; or, when the fan seat 1 has a threaded hole, the bottom end of the fixing member 400 can be provided with an external thread that mates with the threaded hole on the fan seat, and the bottom end of the fixing member 400 is fixed to the fan seat 1 by the threaded engagement with the threaded hole; or, when the fan seat 1 has a hole for passing through the bottom end of the fixing member 400, the fixing member 400 passes through the hole, and the fixing member 400 is threadedly connected to a nut at a position below the fan seat 1, so as to fix the fan seat 1 by lifting it with the nut.

[0091] Thus, the fastener 400 can be easily and detachably connected through the fixing hole 320, so that the fastener 400 of different lengths can be easily adjusted and replaced as needed.

[0092] Reference Figure 1 , Figure 3 , Figure 6 and Figure 11 As shown, in some embodiments, the fixing member 400 is a bolt, and the fan seat positioning device also includes a nut member 500, which is opposite to the fixing hole 320, and the fixing member 400 passes through the nut member 500. The fixing member 400 and the nut member 500 are threadedly connected, allowing the position of the fixing member 400 relative to the positioning rod 300 to be adjustable. For example, the nut member 500 and the positioning rod 300 can be fixedly connected, such as by welding. When the nut member 500 is fixed to the positioning rod 300, it improves the firmness of the fixing member 400 relative to the positioning rod 300. Alternatively, for example, the lower end of the nut member 500 can abut against the positioning rod 300, allowing the nut member 500 to be removed from the positioning rod 300. When the lower end of the nut member 500 abuts against the positioning rod 300, it facilitates replacement of the nut member 500 and also facilitates adjusting the relative position of the fixing member 400 by twisting the nut member 500.

[0093] Thus, the fastener 400 is a bolt. Through the cooperation between the fastener 400 and the bolt, it is convenient to adjust the downward protrusion distance of the fastener 400, so as to make it easier to adjust the height of the fan seat 1 relative to the air duct 10 more accurately.

[0094] Reference Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, the fan base positioning device further includes a sleeve 600. The sleeve 600 is fitted onto the fixing member 400, with one end of the sleeve 600 abutting against the positioning rod 300 and the other end abutting against the fan base 1. Thus, by selecting a sleeve 600 of appropriate length, the distance between the fan base 1 and the positioning rod 300 can be precisely controlled, facilitating more accurate and faster height positioning of the fan base 1, and eliminating the need for measuring tools such as a tape measure. For example, in this embodiment, the bottom end of the fixing member 400 can be threadedly connected to the fan base 1 (using the threaded hole on the fan base 1 for mounting the hydrostatic motor); or, the bottom end of the fixing member 400 can pass through a hole on the fan base 1 (a reserved hole on the fan base 1 for mounting bolts of the hydrostatic motor), and a nut can be connected to the portion of the fixing member 400 below the fan base 1 to secure the fan base 1 and the sleeve 600.
