Description

Technical Field

[0001] This invention relates to the field of wind turbine technology, and in particular to a wind turbine device for multi-angle maintenance. Background Technology

[0002] Current fan units require periodic maintenance of their internal structure, such as filters and the fan itself. Existing maintenance methods primarily involve disassembling the fan casing, inspecting the internal mechanisms, and then reassembling it. This process is problematic because the change in casing position can alter parameters, and the cumbersome installation and disassembly steps increase maintenance costs. While some fan units have access doors at key locations, these doors typically only open to specific directions, limiting maintenance needs. Furthermore, if these access doors are obstructed due to installation requirements, they cannot be opened, necessitating complete unit disassembly. Therefore, current fan unit technology suffers from cumbersome maintenance procedures, limited access locations, and a single fixed angle, failing to consider the limitations imposed by different installation sites.

[0047] The technical solution of this invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] like Figure 1-11 A multi-angle maintenance fan device includes: a casing 1, a fan body 4, and a filter module 2;

[0049] The housing 1 is provided with a first air chamber 103 and a second air chamber 104, and a filter receiving groove 101 that is interconnected between the first air chamber 103 and the second air chamber 104 is provided; both the first air chamber 103 and the second air chamber 104 are provided with air guides 3 at the front and rear positions; the housing 1 is provided with a movable and adjustable first maintenance plate 121 on the upper and lower surfaces of the first air chamber 103, the housing 1 is provided with a movable and adjustable second maintenance plate 122 on the upper and lower surfaces of the second air chamber 104, and the housing 1 is provided with a movable and adjustable first baffle 111 at the front and rear positions of the filter receiving groove 101.

[0050] The fan body 4 is detachably installed in the first air cavity 103 and / or the second air cavity 104, and is connected to the air guide 3 at any position;

[0051] The filter module 2 is movably and adjustablely installed in the filter receiving tank 101, and can be installed or removed from the front or rear opening of the filter receiving tank 101.

[0052] This solution provides a fan device for multi-angle maintenance, which symmetrically arranges the first air chamber 103 and the second air chamber 104, and sets a filter receiving groove 101 between them. The casing 1 is respectively provided with a movable and adjustable first maintenance plate 121, a second maintenance plate 122 and a first baffle 111. Combined with the feature that the filter module 2 can move in the filter receiving groove 101, this application can fix the casing 1 at any angle, and can carry out maintenance on the fan device without disassembling the whole machine while fixing it at any angle. This solves the problem of limited maintenance caused by the limited installation angle of the fan and the problem of disassembling the whole machine during maintenance.

[0053] Specifically, the first air cavity 103 and the second air cavity 104 are symmetrically distributed on the left and right sides of the filter receiving tank 101, and the first air cavity 103, the filter receiving tank 101 and the second air cavity 104 are connected in sequence; both the first air cavity 103 and the second air cavity 104 are provided with air guide ports 3, which can be used as the air inlet or air outlet of the fan device as needed; after the airflow enters from one of the air guide ports 3, it can pass through the filter receiving tank 101 and then be output from the other air guide port 3; the airflow passes through the filter module 2 of the filter receiving tank 101, and the filter module 2 can filter the air to remove impurities in the air. Because the first air chamber 103 and the second air chamber 104 inside the chassis 1 are symmetrically distributed, and the chassis 1 also has an adjustable first inspection plate 121 and a second inspection plate 122 on the upper and lower surfaces of the first air chamber 103 and the second air chamber 104 respectively, they can be adjusted when maintenance is needed, thereby exposing the openings of the first air chamber 103 and the second air chamber 104; for the filter module 2, the filter module 2 can move within the filter receiving groove 101, and when installation or removal is needed, the first baffle 111 can be adjusted to expose the slot of the filter receiving groove at the front or rear of the chassis 1, through which the filter module 2 can be installed or removed. Therefore, the chassis 1 can be fixed at multiple angles, such as horizontally, vertically, or tilted; Figure 1 and 2For example, when the chassis 1 is horizontally fixed, the upper surface, lower surface, left side, and / or right side of the chassis 1 can all be fixed to the corresponding substrate; the chassis 1 only needs to expose the first baffle 111 of the filter receiving groove 101 on the front or rear side, and the filter module 2 can be inspected by driving the first baffle 111 to move; the chassis 1 only needs to expose the upper or lower surface, so that the first inspection plate 121 or the second inspection plate 122 on the upper or lower surface can be moved, and the fan body 4 of the first air cavity 103 or the second air cavity 104 can be inspected. The same applies to vertical fixing and inclined fixing. Meanwhile, the fan body 4 of this solution can be installed in the first air cavity 103 and / or the second air cavity 104. On the one hand, it makes the installation of the fan body 4 more convenient, so that this application can change the position of the fan body 4 as needed to change the direction of airflow. On the other hand, before the fan body 4 is installed, only the first inspection plate 121 or the second inspection plate 122 needs to be adjusted to expose the first air cavity 103 or the second air cavity 104 before the fan body 4 is installed. The installation of the fan body 4 does not require disassembling and reinstalling the whole machine. Moreover, based on the characteristics of the chassis 1 of this application, the installation of the fan body 4 is not affected by the positional resistance of the chassis 1.

[0054] The plate movement adjustment involved in this solution specifically refers to installation at the corresponding opening after disassembly, angle adjustment, movement adjustment, or rotation adjustment.

[0055] Preferably, it further includes: an insulating plate 6;

[0056] The insulating plate 6 is detachably installed in the first air cavity 103 and / or the second air cavity 104, so that the air guide 3 of at least one of the first air cavity 103 and the second air cavity 104 is separated from the filter receiving groove 101 and / or the other air guide 3.

[0057] The baffle plate 6 can be installed in the first air cavity 103 and / or the second air cavity 104. It can be fixed in the cavity by known installation methods, such as screw fixing, slot fixing, clamp fixing, magnetic fixing, etc. When the baffle plate 6 is installed in the first air cavity 103 and / or the second air cavity 104, the airflow in the first air cavity 103 or the second air cavity 104 cannot pass through the baffle plate 6, thereby isolating a certain air guide 3 from the original flow path of the airflow. The isolated air guide 3 can be regarded as unused, or a new airflow path can be formed. Thus, this solution can control the airflow path in the chassis 1 through the baffle plate 6, thereby ensuring that the whole machine is not disassembled while fixing at multiple angles. The airflow path inside the chassis 1 can be adjusted to change the air inlet and outlet, and multiple airflow paths can be set in the chassis 1.

[0058] For example, in one embodiment, the partition plate 6 separates the two air inlets 3 of the first air cavity 103; one of the air inlets 3 is the air inlet end and is connected to the filter module 2 of the filter receiving tank 101 and the second air cavity 104, and the two air inlets 3 of the second air cavity 104 are the air outlet ends.

[0059] In one embodiment, an isolation plate 6 separates the first air cavity 103 from the filter receiving tank 101, and another isolation plate 6 separates the second air cavity 104 from the filter receiving tank 101. The first air cavity 103 and the second air cavity 104 form a dual air duct, and a single fan device can have multiple airflow transmission paths.

[0060] In one embodiment, an isolation plate 6 isolates one of the air inlets 3 of the first air cavity 103 from the other three air inlets 3, and another isolation plate 6 separates one air inlet 3 of the second air cavity 104 from the other air inlet 3 of the second air cavity 104, with one air inlet 3 of the second air cavity 104 as the air inlet and the other air inlet 3 of the second air cavity 104 as the air outlet; the filter receiving tank 101 is provided with filter modules 2 at the front and rear positions; air is drawn in through the air inlet 3 of the air inlet, and the air flows through the filter module 2 of the filter receiving tank 101, the first air cavity 103, the filter module 2 of the filter receiving tank 101 and the second air cavity 104, and then is output from the air inlet 3.

[0061] Therefore, this solution allows for the control of airflow path, number of paths, and flow rate by adjusting the position of the baffle plate 6 in the first air cavity 103 and the second air cavity 104, without disassembling the entire fan or the multi-angle fixed casing 1. Especially for routine maintenance of the fan body 4, when multiple fan bodies 4 are installed in the casing facing forward, backward, or in a mirror image, maintenance of the coarse filter 221, micro filter 222, total heat exchanger 223, and fan body 4, as well as changing the direction of the inlet and outlet air vents, can be performed without disassembling the entire unit, thus avoiding energy loss.

[0062] Preferably, the chassis 1 is provided with a movable and adjustable secondary air baffle 123 on the adjacent side of some of the air guide ports 3, the air guide ports 3 are close to the secondary air baffle 123, and the positions of the secondary air baffle 123 and the adjacent air guide ports 3 can be interchanged.

[0063] The position of the air guide 3 can be interchanged with the secondary air baffle 123 as needed. The air guide 3 is still in a specific position in the first air cavity or the second air cavity, only the orientation angle of the air guide 3 changes. Therefore, when the chassis 1 is installed at multiple angles, the outward protruding air guide 3 is prevented from forming a hindrance with the fixed substrate. This further allows for more installation angles of the fan device and more flexible installation. The angle of the air guide 3 can be flexibly adjusted without changing the position of the air guide 3 in the first air cavity 103 or the second air cavity 104, so that the chassis 1 and the installed substrate are more compatible.

[0064] Preferably, the chassis 1 is provided with interconnected filter receiving slots 101 at the front and rear positions, and the filter modules 2 are respectively disposed in each of the filter receiving slots 101. The slot openings of the filter receiving slots 101 are located on the front and rear sides of the chassis 1. Any filter module 2 can move from one of the filter receiving slots 101 to another filter receiving slot 101.

[0065] In this embodiment, filter receiving slots 101 are respectively located at the front and rear positions of the chassis 1, and the filter receiving slots 101 at the front and rear positions are connected. The slot openings of the filter receiving slots 101 are located on the front and rear sides of the chassis 1. The filter frame 21 can move between the two filter receiving slots 101, thereby enabling the filter assembly 22 to move from one filter receiving slot 101 to the other filter receiving slot 101. This structure allows the chassis 1 to be fixed, and when the slot opening of one filter receiving slot 101 is restricted, the filter frame 21 inside the chassis 1 can be pulled out from the other unrestricted filter receiving slot 101, ultimately ensuring that the chassis 1 is not restricted in position during installation. This embodiment allows the chassis 1 to be fixed at multiple angles, making it easier for operators to perform multi-angle maintenance on the filter assembly 22.

[0066] Preferably, the chassis 1 has a box opening 102 on the upper and lower surfaces of the filter receiving tank 101, and a movable and adjustable second baffle 112 is provided in the box opening 102, and the filter frame 21 exposes the filter module 2 through the box opening 102.

[0067] In addition to the slots of the filter housing 101 exposed on the front and rear sides, the chassis 1 also has openings 102 on the top and bottom. When troubleshooting the filter components 22 at the front and rear positions, the second baffle 112 can be adjusted to expose the openings 102, thus revealing the filter components 22. The openings 102 allow workers to directly observe the filter components 22 of the filter frame 21, especially enabling workers to inspect the fan unit from bottom to top. Workers can troubleshoot problems without having to completely remove the filter frame 21, only needing to remove the second baffle 112, thereby further improving the maintenance efficiency of the filter structure in the fan. Furthermore, since the chassis 1 has openings 102 on both the top and bottom, combined with the slots of the filter housing 101 at the front and rear positions, multiple sides of the chassis 1 can expose openings with different functions, thus enabling the fan to be inspected from multiple angles, and the maintenance of the chassis 1 is not limited by angle.

[0068] More preferably, the filter assembly 22 includes: a coarse filter 221, a micro filter 222, and a total heat exchanger 223;

[0069] The coarse filter 221, the micro filter 222, and the total heat exchanger 223 are respectively installed on the filter frame 21.

[0070] The coarse filter 221 is used for coarse filtration, filtering out large particles in the air to achieve a coarse filtration effect. The micro filter 222 is used for micro filtration, filtering out small particles in the air to achieve a fine filtration effect. The total heat exchanger 223 can preheat or precool the fresh air introduced into the fan system by recovering waste heat from the air. The coarse filter 221, micro filter 222, and total heat exchanger 223 are all components that require routine maintenance. In this embodiment, the coarse filter 221, micro filter 222, and total heat exchanger 223 are simultaneously installed in the filter frame 21. The filter frame 21 can be periodically removed to perform simultaneous maintenance on the coarse filter 221, micro filter 222, and total heat exchanger 223, significantly shortening the inspection time of the fan unit without disassembling other parts of the fan.

[0071] Furthermore, the filter frame 21 is provided with an adjustable third baffle 23 on its side at the total heat exchanger 223.

[0072] The third baffle 23 is located on the side of the filter frame 21. When the total heat exchanger 223 needs to be repaired, only the second baffle 112 at the bottom of the chassis 1 needs to be removed, and then the third baffle 23 on the side of the filter frame 21 needs to be removed. The total heat exchanger 223 can be repaired directly from the bottom of the chassis 1. The total heat exchanger 223 inside the chassis 1 can be repaired without disassembling the whole machine, thereby further simplifying the repair steps of the fan unit for the total heat exchanger 223 and further avoiding the problems of cumbersome steps, complex structure and scattered parts, resulting in high replacement costs and long time.

[0073] The filter frame 21 is provided with multiple filter slots 211, and the coarse filter 221, the micro filter 222 and the total heat exchanger 223 are respectively limited and installed in different filter slots 211.

[0074] The filter frame 21 itself has multiple filter compartments 211, each of which can be fitted with a coarse filter 221, a micro filter 222, or a total heat exchanger 223, thereby fixing the positions of the coarse filter 221, micro filter 222, and total heat exchanger 223. Different filter compartments 211 are set independently, so maintenance of one filter compartment 211 will not affect the others. Furthermore, the coarse filter 221, micro filter 222, and total heat exchanger 223 can be distributed according to a conventional filtration sequence; for example, coarse filtration is typically performed first, followed by fine filtration. Figure 6 The coarse filter 221, the micro filter 222, and the total heat exchanger 223 can be distributed sequentially along the direction from the air inlet to the air outlet of the casing 1.

[0075] The coarse filter 221, the micro filter 222, and / or the total heat exchanger 223 are movably installed in the filter compartment 211.

[0076] The coarse filter 221, the micro filter 222, and the total heat exchanger 223 can move within the filter compartment 211. They can attach their outer walls to the inner wall of the filter compartment 211, thereby moving along the inner wall of the filter compartment 211 during movement. This improves the smoothness of removing the coarse filter 221, the micro filter 222, or the total heat exchanger 223 and reduces the resistance during removal.

[0077] The filter receiving tank 101 is provided with a support plate 212; the support plate 212 is disposed on both sides of the filter frame 21; the support plate 212 is provided with a horizontal part 2121 and a vertical part 2122, the vertical part 2122 is vertically disposed on the horizontal part 2121; the horizontal part 2121 is attached to the upper or lower surface of the filter frame 21; the vertical part 2122 is attached to the left or right side of the filter frame 21.

[0078] The tray 212 is located on both sides of the filter frame 21, either above or below. The vertical part 2122 of the tray 212 contacts the two sides of the filter frame 21, allowing the two sides of the filter frame 21 to move along the horizontal length of the vertical part 2122, thus providing horizontal guidance for the two sides of the filter frame 21. The horizontal part 2121 of the tray 212 contacts the top and bottom surfaces of the filter frame 21, which can limit the height of the filter frame 21, thereby preventing vertical displacement of the filter frame 21. Thus, the top, bottom, left, and right sides are all attached to the outer surface of the filter frame 21, which can ensure the accurate installation of the filter frame 21 and improve the smoothness of the movement of the filter frame 21 in the filter receiving tank 101.

[0079] Preferably, it further includes: a fan mounting structure 7;

[0080] The fan mounting structure 7 includes: a base 71, a fixing plate 72, an air outlet plate 74, a base fastener 75, a fan fastener 76, and a connecting fastener 77.

[0081] The base 71 detachably fixes the fan body 4 to the first air cavity 103 or the second air cavity 104; the base 71 is provided with longitudinally and transversely arranged base holes 711, and the base fasteners 75 are detachably installed in the base holes 711; the base fasteners 75 respectively fix a pair of fixing plates 72 to the base 71 along the arrangement direction of the base holes 711, so that the pair of fixing plates 72 are fixed in a longitudinal or transverse arrangement; a limiting groove 713 is formed between the two fixing plates 72; the air outlet plate 74 is limited in the limiting groove 713; the fan fasteners 76 fix the air outlet plate 74 to the fan outlet of the fan body 4; the connecting fasteners 77 are distributed along the length of the fixing plates 72 and detachably fix the fixing plates 72 and the air outlet plate 74.

[0082] This solution provides a fan mounting structure 7 that is easy to disassemble. Its fixing plate 72 is fixed to the base 71 by the base fastener 75. On the one hand, the extension direction of the limiting groove 713 can be adjusted, so that the fan body 4 can be fixed to the base 71 at multiple angles. On the other hand, the fixing plate 72 can be fixed at multiple angles, and the connecting fastener 77 is set at the front and rear positions of the fixing plate 72. The fixing plates 72 are set in pairs. Therefore, this application can disassemble the fan body 4 in two directions, which facilitates the disassembly of the fan body 4. Combined with the fan device of this application, which has the characteristics of multi-angle fixing and no need for disassembly of the whole machine, the fan mounting structure 7 used in this embodiment can further improve the maintenance efficiency of the fan device, thereby further solving the problem of limited maintenance caused by the limited fan installation angle and the problem of disassembly of the whole machine during maintenance.

[0083] Specifically, the base 71 is provided with multiple base holes 711, which are arranged longitudinally and laterally. Therefore, the fixing plate 72 can be fixed to the longitudinally arranged base holes 711 or the longitudinally arranged base holes 711, thereby extending the limiting groove 713 formed between the fixing plates 72 longitudinally or laterally. When it is necessary to install the fan body 4, one fixing plate 72 can be installed first, and the fixing plate 72 can be fixed along the longitudinally arranged (or laterally arranged) base holes 711. The fixing plate 72 is fixed to the base holes 711 by the base fastener 75. In one embodiment, another fixing plate 72 is fixed to the base holes 711 by the base fastener 75, and then the fan fastener 76 is used to fix the air outlet plate 74 to the fan outlet of the fan body 4. The air outlet plate 74 is directly installed in the limiting groove 713 between the two fixing plates 72. In one embodiment, the fan outlet of the fan body 4 is installed on the vent plate 74 using fan fasteners 76, and one side of the vent plate 74 is fixed to another fixing plate 72 using connecting fasteners 77. The connecting fasteners 77 are distributed along the length of the fixing plate 72. The fan body 4, the vent plate 74, and the fixing plate 72 are pre-assembled to form an assembly unit. When the fan body 4 needs to be installed, the assembly unit is directly installed on the base 71. The part of the assembly unit on the fixing plate 72 is fixed to the base hole 711 using base fasteners 75, and the other side of the vent plate 74 is fixed to the installed fixing plate 72 using connecting fasteners 77, thereby fixing the entire fan body 4 to the base 71. During the above installation process, the adjusting ends of the base fastener 75, fan fastener 76, and connecting fastener 77 are preferably positioned on the side facing the worker; similarly, since the fixing plates 72 are arranged in pairs, they are symmetrically distributed on both sides of the fan body 4. When it is necessary to disassemble the fan body 4, one can choose to stand on either the left or right side of the fan body 4 as needed. In one embodiment, such as Figure 8 When the fixing plate 72 extends longitudinally, the fan body 4 is vertically fixed, and the two fixing plates 72 are equidistant from the worker. At this time, the base fastener 75, fan fastener 76, and connecting fastener 77 are not difficult to disassemble, and any disassembly method can be used. For example, the base fastener 75 of the two fixing plates 72 can be directly disassembled, thereby simultaneously disassembling the fan body 4, the air outlet plate 74, and the fixing plate 72. Alternatively, the fan fastener 76 can be directly disassembled to remove the fan body 4. In one embodiment, such as... Figure 9 This can be a top view or a front view when the fan body is horizontally fixed. When the fixing plate 72 extends horizontally, there is a distance difference between the fixing plate 72 and the worker. The fan body 4 will cover one of the fan fasteners 76 that is far away from the worker. At this time, the base fastener 75 on the fixing plate 72 closest to the worker can be removed first, and then the connecting fastener 77 on the fixing plate 72 far away from the worker can be removed, thereby disassembling the assembly unit.

[0084] The base fastener 75, the fan fastener 76, and the connecting fastener 77 are known mechanisms with fixing functions, such as bolts, studs, screws, pins, etc., or nuts that are used in conjunction with them.

[0085] Preferably, the fixing plate 72 has a horizontal portion 721 and a vertical portion 722; the horizontal portion 721 is mounted to the base 71 by the base fastener 75;

[0086] The air vent plate 74 is provided with a side plate 741 and a bottom plate 742; the side plate 741 is installed on both sides of the bottom plate 742, and the bottom plate 742 is limited in the limiting groove 713; the vertical part 722 and the side plate 741 are respectively provided with a fixing side hole 7201 and a through hole 7202 on both sides of the limiting groove 713; the connecting fastener 77 is limited in the fixing side hole 7201 and fixes the vertical part 722 and the side plate 741; the fixing side hole 7201 of the fixing plate 72 on one side is aligned with the through hole 7202 of the fixing plate 72 on the other side.

[0087] The fixing plate 72 has a horizontal portion 721 and a vertical portion 722. The horizontal portion 721 is used to install the fixing plate 72 onto the base 71 via the base fastener 75, thereby fixing the position of the fixing plate 72. The vertical portion 722 is used to install the connecting fastener 77. The connecting fastener 77 passes through the fixing side holes 7201 of both the vertical portion 722 and the side plate 741, thereby fixing the fixing plate 72 and the air vent plate 74. The structure of the fixing plate 72 and the air vent plate 74 is simpler, making installation and disassembly more convenient and faster.

[0088] When the installation position of a certain fixed plate 72 is far from the worker, a through-hole 7202 can be provided on the fixed plate 72 and the air outlet plate 74. The position of the through-hole 7202 is cleverly designed; the through-hole 7202 of one fixed plate 72 is aligned with the fixing side hole 7201 of the other fixed plate 72. The worker can insert an adjuster into the through-hole 7202 of one fixed plate 72, and the adjuster passes through the through-hole 7202 and abuts against the fixing side hole 7201 of the fixed plate 72 far from the worker, thereby abutting the adjusting end of the fastener 77. This reduces the installation difficulty of the fastener 77 and improves the installation efficiency of the fan body 4. This structure is particularly suitable for situations where the fan body of this application can be fixed at multiple angles. When the adjusting end far from the worker is difficult to adjust, the adjustment can continue to be made through the nearby through-hole to the far fixing side hole.

[0089] Preferably, the adjusting end of part of the connecting fastener 77 is located on the surface of the vertical portion 722, or on the side of the side plate 741 within the limiting groove 713.

[0090] The adjusting end of the fastener 77 refers to a structure or position used to adjust the tightness of the fastener 77. For example, in some embodiments, when the fastener 77 is a screw, the adjusting end is the screw head; in some embodiments, when the fastener 77 is a combination of a screw and a nut, the adjusting end can be the screw head and / or the nut. Under this structure, the adjusting end of the fastener 77 can be located on the surface of the vertical portion 722 or on the side of the side plate 741 within the limiting groove 713, as needed. Workers can position the adjusting end inside or outside the limiting groove 713 as needed, thus facilitating subsequent installation and disassembly when the fan body 4 is installed vertically or horizontally.

[0091] Some of the fixed side holes 7201 are provided with an internal thread structure, and the connecting fastener 77 is a connecting screw 771, which is threaded into the fixed side hole 7201; or some of the connecting fasteners 77 include: a connecting screw 771 and a connecting nut 772, wherein the connecting screw 771 passes through the fixed side holes 7201 of both the fixed plate 72 and the air vent plate 74 and then engages with the connecting nut 772.

[0092] The fastener 77 can function as a connecting screw 771, directly engaging with the fixing side hole 7201 via its threaded structure; alternatively, the fastener 77 can pass through the fixing side holes 7201 of both the fixing plate 72 and the vent plate 74, and then engage with the connecting nut 772. Workers can choose the optimal fixing method according to their specific needs.

[0093] The fan body 4 has a mounting surface 731 on the outer edge of the fan outlet; the air outlet plate 74 and the mounting surface 731 are respectively provided with a plurality of coaxially aligned fan mounting holes 730; the fan fastener 76 is fixed to the fan mounting holes 730 on both the air outlet plate 74 and the mounting surface 731.

[0094] The mounting surface 731 provides a contact surface to connect the fan body 4 to the air outlet plate 74, thereby increasing the contact area between the fan body 4 and the air outlet plate 74 and making the fixation more stable. At the same time, the mounting surface 731 has multiple fan mounting holes 730. The fan fasteners 76 pass through the fan mounting holes 730 on both the air outlet plate 74 and the mounting surface 731, thereby fixing the air outlet plate 74 and the fan body 4. During installation and disassembly, the corresponding fan mounting hole 730 can be selected as needed to install the fan fasteners 76.

[0095] The fan fastener 76 can connect the air outlet plate 74 and the mounting surface 731 in any way. For example, in some embodiments, the fan fastener 76 passes sequentially through the fan mounting holes 730 in the mounting surface 731 and the air outlet plate 74, and the fan fastener 76 is threaded into the fan mounting holes 730. In some embodiments, when the fan fastener 76 is a screw, it passes through the fan mounting holes 730 in the mounting surface 731 and the air outlet plate 74, and then engages with a nut. In this embodiment, the base 71 and the air outlet plate 74 are spaced apart. In the optimal implementation...

[0096] The base 71 or the air vent plate 74 is provided with a groove 712; the fan fastener 76 is located in the groove 712 at one end away from the air vent plate 74, and the other end of the fan fastener 76 extends out of the groove 712, and the base 71 and the air vent plate 74 are in planar contact.

[0097] The base 71 or the air vent plate 74 is provided with a groove 712. The groove 712 can be located on the contact surface between the base 71 and the air vent plate 74. One end of the fan fastener 76 is confined within the groove 712, and the other end extends out of the groove 712 and engages with the air vent plate 74. Alternatively, the groove 712 can be provided on the other side of the air vent plate 74 away from the contact surface. The fan fastener 76 can be directly embedded in the air vent plate 74 as a screw in the groove 712. The screw head is confined within the groove 712 (e.g., welded), and one end of the screw extends out of the groove 712, passes through the mounting surface 731, and engages with a nut to fix the fan. Thus, in this embodiment, the base 71 and the air vent plate 74 can have planar contact, making the installation of the fan body 4 more stable.

[0098] The fan fastener 76 includes: a fan screw 761 and a fan nut 762;

[0099] The fan body 4 has a mounting surface 731 on the outer edge of the fan inlet;

[0100] The screw of the fan screw 761 passes through the air outlet plate 74 and the mounting surface 731, and then engages with the fan nut 762, so that the fan outlet of the fan body 4 is connected to the air outlet plate 74.

[0101] The fan fastener 76 preferably uses fan screws 761 and fan nuts 762, which are easy to install and remove. Installation and removal can be completed simply by turning the screw head of the fan screw 761 or the fan nut 762 with a screwdriver. The screw head of the fan screw 761 or the fan nut 762 can be placed in the limiting groove 713. Combined with the feature that the adjusting end of the connecting fastener 77 of this application is located on the surface of the vertical part 722 or on the side of the side plate 741 within the limiting groove 713, it is more convenient and faster for workers to install and remove the fan body 4.

[0102] The base fastener 75 includes: a base screw 751;

[0103] The base screw 751 passes through the fixing plate 72 and is threaded into the base hole 711; the screw head of the base screw 751 is located on the surface of the fixing plate 72.

[0104] The installation of the fixing plate 72 is convenient. It only requires the base screw 751 to be passed through the fixing plate 72 and threaded into the base hole 711. The screw head of the base screw 751 presses the fixing plate 72 against the base 71, thereby limiting the fixing plate 72 to the base 71. When the screw head of the base screw 751 is on the surface of the fixing plate 72, its position is closer to the worker, making it easier for the worker to adjust. The installation and disassembly of the fan body 4 are more convenient and faster for the worker.

[0105] The technical principles of this solution have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this solution and should not be construed as limiting the scope of protection of this solution in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this solution without inventive effort, and these embodiments will all fall within the scope of protection of this solution.
