[0034] Please also read Figures 1 to 5 .in, Figure 1 It is a structural schematic diagram of the fan fixing device of the utility model during application configuration. Figure 2 , 5 It is a schematic diagram of the relevant structure of the fan fixing device of the utility model. Figure 3 , 4 This is a schematic diagram of the relevant structure of the fan fixing device of the utility model when it is fixed to a steel beam.

[0035] As shown in the figure, the utility model provides a fan fixing device 1, which is used to fix a fan module 21 to a steel beam 3. The fan module 21 is preferably a ceiling fan, and the steel beam 3 is preferably an H-shaped steel beam. In different embodiments, it can also be fixed to other types of steel beams 3, so the utility model is not limited to this.

[0036] The support platform 11 may be made of metal material, for example, made of aluminum alloy by extrusion molding or die casting, preferably made of aluminum alloy by extrusion molding. The cross-section of the support platform 11 is generally a concave structure, and has light weight and good structural strength. The support platform 11 has two opposite surfaces, which are the first surface 111 and the second surface 112. In the direction facing the steel beam 3, the first surface 111 is the top surface, and in the direction relative to the steel beam 3, the second surface 112 is the bottom surface. The second surface 112 is configured to fix the fan module 21; the detailed method of fixing the fan module 21 will be further described later.

[0037] Among them, two tracks 12 are provided on the first surface 111 at intervals along the first direction D1. Preferably, the two tracks 12 are respectively arranged on two bosses of the support platform 11 whose cross section is a concave structure. In addition, each track 12 is arranged along the second direction D2, and the first direction D1 is perpendicular to the second direction D2. Further, the cross section of the track 12 may be, for example, a convex structure. Among them, the upper part of the track 12 with the convex structure is the connection between the track 12 and the first surface 111, and the lower part of the track 12 with the convex structure is the bottom surface of the track 12, that is, the width of the bottom of the track 12 is greater than the width of the opening of the track 12 on the first surface 111.

[0038] Two clamping sets 13 are respectively arranged on each of the rails 12. The clamping set 13 has two clamping units 131. The clamping unit 131 can be made of metal material, preferably aluminum or aluminum alloy. The two clamping units 131 are relatively and movably arranged on the rail 12. The clamping unit 131 is integrally formed from the first surface 111 to the second surface 112 and includes a slider 132 and a clamping portion 133 in sequence. The cross-sectional shape of the slider 132 along the second direction D2 can correspond to the cross-sectional shape of the rail 12 and present a convex structure; thereby, the slider 132 can be displaced in the rail 12 without deviation. The slider 132 is provided with a screw hole 134 along the second direction D2. Since the two clamping units 131 are relatively arranged on the rail 12, the two screw holes 134 of the two clamping units 131 on the rail 12 are also in opposite or opposite rotation directions. Thus, two screw rods 136 are respectively disposed in the screw holes 134, and the two screw rods 136 are respectively subjected to force and rotated to drive the two clamping units 131 to be relatively close to or relatively separated. Preferably, the driving end of the screw rod 136 (for example, the end adjacent to the first side frame 141) can be configured as a non-circular structure, such as a hexagonal structure, so that the operator or the unmanned working machine can drive the screw rod 136 to rotate by the non-circular structure, thereby driving the two clamping units 131 to be relatively close to or relatively separated.

[0039] In addition, the clamping portion 133 is arranged corresponding to the steel beam 3. Specifically, the clamping portion 133 has a clamping groove 135, and the shape of the clamping groove 135 corresponds to the shape of the side of the steel beam 3, so that the clamping groove 135 can be used to engage or fix to the side of the steel beam 3, so that the fan fixing device 1 as a whole can fix the steel beam 3, and then the fan module 21 below the fan fixing device 1 can be hung on the steel beam 3. Preferably, the opening width of the clamping groove 135 is greater than the bottom width of the clamping groove 135; this configuration allows the clamping groove 135 to be smoothly or conveniently engaged or fixed to the side of the steel beam 3.

[0040] Incidentally, the fan fixing device 1 of the utility model can be configured as above, and the fan fixing device 1 and the fan module 21 thereunder can be fixed on the steel beam 3 by an unmanned machine. For example, after alignment, the unmanned machine can raise the fan fixing device 1 and the fan module 21 thereunder to the position of the steel beam 3, and then the unmanned machine rotates the two screws 136, so that the two clamping units 131 of each group can be clamped, engaged or fixed on both sides of the steel beam 3. Moreover, since the opening width of the clamping groove 135 is greater than the bottom width of the clamping groove 135, the unmanned machine can make the clamping groove 135 smoothly or conveniently clamped, engaged or fixed on the side of the steel beam 3 when working, and the precise alignment procedures are omitted, thereby increasing the convenience during installation.

[0041] It is worth mentioning that the track 12 connects a first side 113 and a second side 114 of the supporting platform 11 opposite to each other along the second direction D2. It is convenient to install the two clamping units 131 into the track 12. The fan fixing device 1 includes a first side frame 141 and a second side frame 142 made of metal material, for example. The first side frame 141 is fixed to the first side 113, and the second side frame 142 is fixed to the second side 114. For example, the first side frame 141 and the second side frame 142 can be fixed to the two sides (the first side 113 and the second side 114) of the supporting platform 11 by locking, welding, etc., so as to prevent or stop the clamping unit 131 from leaving the track 12. In addition, the first side frame 141 has two through holes 143 corresponding to the two screw rods 136, so that the screw rods 136 can pass through, so that the screw rods 136 can be rotated manually or by an unmanned machine, so that the two clamping units 131 of each group are relatively close to each other, and then clamped, engaged or fixed to the side of the steel beam 3. Preferably, the first side frame 141 can be provided with components such as nuts or bearings at both ends of the through hole 143, so that the screw rods 136 can be positioned and stably arranged. Of course, the second side frame 142 can also be provided with corresponding through holes, and nuts or bearings can be provided at both ends of the through holes, so that the screw rods 136 can be further positioned and stably arranged.

[0042] It is also worth mentioning that the first side frame 141 and the second side frame 142 can be substantially in the shape of a "〔" structure, that is, the two ends of the first side frame 141 and the second side frame 142 are arranged in a relatively distant manner and have an angle, and the angle is not equal to 180 degrees. The first side frame 141 and the second side frame 142 have an adjustment connector 144 at both ends, and the fan module 21 has a plurality of connecting rod groups 211, and one end of each connecting rod group 211 is respectively disposed on each of the adjustment connectors 144. The adjustment connector 144 can be an opening formed by integrally bending the first side frame 141 and the second side frame 142, and a nut is rotatably provided on the opening, and then a screw is disposed in the nut; one end of the screw can be a C-shaped structure or an O-shaped structure for connection with the connecting rod group 211. Thus, the position of the screw rod can be adjusted by rotating the nut, thereby adjusting the tension of the connecting rod assembly 211, etc., so that when the fixation between the fan module 21 and the carrier platform 11 occurs (for example, the fan module 21 is separated from the carrier platform 11), the fan module 21 can be restricted by the connecting rod assembly 211 and the adjustment connector 144 to prevent it from falling.

[0043] Please configure Figures 1 to 5 Also see Figure 6 . Figure 62 is a schematic diagram of a fan device. The fan device 2 of the present invention is fixed on the steel beam 3 by using the fan fixing device 1 in the above embodiment.

[0044] As shown in the figure, the fan device 2 includes the fan fixing device 1 as in the above embodiment, a connecting column set 22 and a fan module 21. The detailed configuration and operation of the fan fixing device 1 are the same as in the above embodiment, and will not be further described here.

[0045] It is worth mentioning that the second surface 112 of the support platform 11 of the fan fixing device 1 is provided with two metal connecting frames 15 spaced apart along a second direction D2. Each connecting frame 15 has a first assembly hole 151 and an angle adjustment slot 152, and the angle adjustment slot 152 is configured in an arc shape with the first assembly hole 151 as a circular hole.

[0046] The connecting column group 22 can be a column made of metal material, which is equipped with corresponding bolts, washers, nuts, through holes and / or screw holes. One end of the connecting column group 22 is fixed between the two connecting frames 15, and the other end of the connecting column group 22 fixes the fan module 21. The connecting column group 22 is provided with two second assembly holes 221 corresponding to the first assembly hole 151 and the angle adjustment slot 152. In other words, the connecting column group 22 and the fan fixing device 1 can be positioned and used as the axis by assembling the first assembly hole 151 and the second assembly hole 221, and the angle between the fan fixing device 1 and the connecting column group 22 can be adjusted by assembling the second assembly hole 221 and the angle adjustment slot 152 to fix them. In this way, when the fan device 2 is fixed to the steel beam 3 by using the fan fixing device 1, the fan module 21 can have a specific or predetermined air outlet angle or air outlet direction.

[0047] It should be particularly noted that the fan module 21 has a telecommunication connection line 212, and one or more magnetic components 213 are arranged on the telecommunication connection line 212. The magnetic component 213 can be a magnetic ring sleeved on the telecommunication connection line 212, or the outer sheath of the telecommunication connection line 212 can be doped with magnetic powder, etc., so that the telecommunication connection line 212 can be magnetically attracted to a suitable metal, such as a steel beam 3. In this way, after the staff or the unmanned working machine completes the assembly of the fan fixing device 1 and the steel beam 3, it can place the telecommunication connection line 212 on the steel beam 3 or close to the steel beam 3, and the magnetic component 213 can make the telecommunication connection line 212 adsorbed on the steel beam 3 or stably carried on the steel beam 3. Therefore, the fan device 2 of the utility model can facilitate operations such as wiring or pulling wires.

[0048] Please also read Figure 7 and Figure 8 , which are respectively a first installation schematic diagram and a second installation schematic diagram of the fan device of the present invention.

[0049] As shown in the figure, the fan device 2 is fixed to the steel beam 3 by an automated installation device 23. The automated installation device 23 can be a seat body with a lifting column 231 or a self-propelled vehicle with a lifting column 231; in this embodiment, the automated installation device 23 uses a self-propelled vehicle as a demonstration, and in actual use, relevant personnel can use a remote control to control the self-propelled vehicle to move to a predetermined position and further control the lifting column 231 to rise.

[0050] Furthermore, a bearing platform 232 is provided on the lifting column 231. A position-limiting bearing portion 233 is extended from one side of the bearing platform 232, and the position-limiting bearing portion 233 is configured to detachably bear the fan device 2. The position-limiting bearing portion 233 can be a plate body extending from one side of the bearing platform 232 or two plate bodies spaced apart, and position-limiting blocks are protruding from the plate body corresponding to the two sides of the bearing platform 11 and the sides of the first side frame 141 and the second side frame 142. In this way, the fan device 2 can be properly accommodated in the position-limiting bearing portion 233 without causing problems such as lateral displacement.

[0051] In addition, the carrying platform is provided with a locking module 234, and the two rotating drive shafts 235 of the locking module 234 are respectively detachably connected to the two screw rods 136. The carrying platform is provided with a camera device 236, and the camera device 236 takes pictures in the direction of the fan device 2 and transmits the image signal to an electronic device through a wired or wireless method. The electronic device can be integrated with the remote control into the same device, such as a tablet computer, that is, the relevant personnel can control the rise or fall of the lifting column 231 while viewing the display of the image signal.

[0052] Furthermore, the locking module 234 may include a front-to-back displacement drive unit and a rotation drive unit; the front-to-back displacement drive unit drives the rotation drive shaft 235 to move toward the screw rod 136 or away from the screw rod 136. The rotation drive unit can drive the rotation drive shaft 235 to rotate forward or reverse. The detailed technical means of the front-to-back displacement drive unit, the rotation drive unit and the rotation drive shaft 235 are well known to ordinary technicians in the relevant technical field, and will not be described in detail here.

[0053] In actual use, before or after the automated installation device 23 has moved to the position, the relevant personnel can first place the fan device 2 on the position-limiting bearing portion 233, and connect the sleeve of the rotating drive shaft 235 to the screw 136. Then, when the automated installation device 23 has moved to the position, the lifting column 231 is controlled to rise so that the fan device 2 is close to the steel beam 3. During the process, the relevant personnel can view the relative position of the clamp set 13 and the steel beam 3 through the electronic device.

[0054] After adjusting to the appropriate relative position, the relevant personnel can control the rotation drive shaft 235 to rotate, so that the two clamping units 131 of each group can be clamped, engaged or fixed on both sides of the steel beam 3. Then, the relevant personnel control the rotation drive shaft 235 to disengage the screw rod 136 and control the lifting column 231 to descend, so that the fan device 2 fixed to the steel beam 3 is disengaged from the limit bearing part 233 to complete the installation.

[0055] Incidentally, in the follow-up, the relevant personnel can use the unmanned aerial vehicle to arrange the telecommunication connection line 212 on the steel beam 3. In addition, in special cases, such as the steel beam 3 cannot be magnetically attracted by the telecommunication connection line 212, the telecommunication connection line 212 can be arranged using a nail gun.

[0056] The fan device of the utility model cooperates with the automatic installation device to improve the inconvenience of the relevant personnel needing relevant certificates when working at high altitudes and avoid the dangers that may occur when the relevant personnel work at high altitudes.

[0057] The above description is for illustrative purposes only and is not intended to be limiting. Any equivalent modifications or changes made to the present invention without departing from the spirit and scope of the present invention shall be included in the appended claims.
