[0051] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] like Figures 1 to 3 As shown, this embodiment provides a blower cooling device, including a support frame 1, a rotating frame 2, a cooling structure 3, and a drive structure 4. The support frame 1 is movably mounted on the ground, and the rotating frame 2 is rotatably mounted on the support frame 1 in a horizontal direction. The cooling structure 3 includes a mounting base 31, a fixing plate 32, and a cooling component 33. The mounting base 31 is mounted on the rotating frame 2, and the fixing plate 32 is mounted on the mounting base 31. A rolling element 320 is provided on the fixing plate 32. The cooling component 33 is mounted on the fixing plate 32 and rotatably abuts against the rolling element 320 in a vertical direction. The cooling component 33 has an active state that can rotate in a vertical direction and a locked state that cannot rotate. In the active state, maintenance personnel can flexibly adjust the blowing direction of the cooling component 33. After adjusting to a suitable direction, the cooling component 33 is then adjusted to the locked state to ensure accurate blowing direction and simple and convenient operation. The drive structure 4 is mounted on the support frame 1. The output end of the drive structure 4 is hinged to the rotating frame 2. Under the drive of the drive structure 4, the rotating frame 2 can rotate around the horizontal direction, thereby realizing the adjustment of the pitch angle of the heat dissipation component 33, ensuring air circulation in the maintenance area, and creating a healthy and comfortable environment for maintenance personnel. At the same time, the device is easy to move and can be applied to various maintenance workshops.

[0053] Specifically, a rotating shaft is threaded through one end of the rotating frame 2. The rotating shaft extends horizontally and is rotatably mounted on the support frame 1 to achieve a rotatable connection between the rotating frame 2 and the support frame 1. Additionally, as... Figure 2 As shown, the mounting base 31 has multiple first connecting holes 312, and the rotating frame 2 has multiple second connecting holes 20. Each of the first connecting holes 312 corresponds to one of the second connecting holes 20. Fasteners 21 pass through the corresponding first connecting holes 312, second connecting holes 20, and nuts 22 in sequence. Nuts 22 abut against the side of the rotating frame 2 opposite to the mounting base 31, thus detachably mounting the mounting base 31 onto the rotating frame 2. For example, four first connecting holes 312, four second connecting holes 20, four fasteners 21, and four nuts 22 are provided. The fasteners 21 are commonly used bolts.

[0054] Optionally, such as Figure 1 As shown, the support frame 1 has multiple casters 10 on its bottom side to facilitate the overall movement of the device. Specifically, in this embodiment, the support frame 1 has four sets of directional wheels and one set of omnidirectional wheels on its bottom side. The directional wheels are used to ensure stability and high load-bearing capacity when in a straight line, while the omnidirectional wheels are used to assist in steering. Direction adjustment is achieved through flexible rotation at a single point, facilitating the overall flexible movement of the device. In other embodiments, the type and number of casters 10 can be set as needed, and no specific limitation is made here.

[0055] Optionally, continue to refer to Figure 1 An operating handle 11 is provided on one side of the support frame 1, allowing the operator to move the device by gripping the operating handle 11. Specifically, in this embodiment, the operating handle 11 is made of round steel. The surface of round steel is relatively smooth, providing a comfortable feel and preventing hand scratches. Furthermore, the smooth surface is easy to clean and maintain, and round steel offers high cost-effectiveness.

[0056] Optionally, such as Figure 2 As shown, the heat dissipation assembly 33 includes a rotating base 331, a locking member 332, and a heat dissipation component 333. The rotating base 331 rotatably abuts against the rolling member 320, and the heat dissipation component 333 is disposed on the rotating base 331. An adjustment hole 3310 is provided on the rotating base 331, and a fastening hole 321 is provided on the fixing plate 32. The locking member 332 passes through the adjustment hole 3310 and is screwed into the fastening hole 321. Rotating the rotating base 331 adjusts the airflow direction of the heat dissipation component 333. After adjustment, screwing on the locking member 332 fixes the relative position of the rotating base 331 and the fixing plate 32, ensuring accurate and stable airflow direction. The operation is simple and convenient, facilitating adjustment of the airflow direction.

[0057] Specifically, continue to refer to Figure 2 In this embodiment, the adjustment hole 3310 on the rotating seat 331 is arc-shaped. When it is necessary to adjust the air blowing direction of the heat sink 333, the locking member 332 is turned so that the rotating seat 331 can be adjusted to a state where it can rotate freely around the vertical direction. The rotating seat 331 can be rotated without removing the locking member 332. After the air blowing direction of the heat sink 333 is adjusted to the correct position, the locking member 332 is turned again to complete the relative position of the rotating seat 331 and the fixed plate 32, making the operation more convenient and efficient.

[0058] More specifically, there are two arc-shaped adjustment holes 3310, and correspondingly, there are also two locking elements 332 and two fastening holes 321. For example, the locking element 332 is a commonly used bolt, and the fastening hole 321 is a threaded hole.

[0059] Furthermore, such as Figure 2 As shown, the mounting base 31 has a protruding limiting part 311, the fixing plate 32 has a first limiting hole 322, and the rotating base 331 has a second limiting hole 3311. The limiting part 311 passes through the first limiting hole 322 and the second limiting hole 3311 in sequence. The above arrangement facilitates the installation and positioning of the fixing plate 32, and also improves the stability of the rotating base 331 during rotation, effectively preventing the rotating base 331 from slipping or shifting.

[0060] Furthermore, multiple rolling elements 320 are arranged at circumferential intervals along the first limiting hole 322 to ensure smooth rotation of the rotating seat 331. Specifically, in this embodiment, the rolling elements 320 are ball bearings.

[0061] Optionally, refer to Figure 2 The heat sink 333 includes a protective cover 3331, a first drive mechanism 3332, and multiple fan blades 3333. The protective cover 3331 is mounted on a rotating base 331 and surrounds an installation chamber. The first drive mechanism 3332 is located within the installation chamber, and the multiple fan blades 3333 are also located within the installation chamber and rotatably mounted at the output end of the first drive mechanism 3332. The first drive mechanism 3332 drives the multiple fan blades 3333 to rotate, thereby achieving airflow. The protective cover 3331 effectively prevents maintenance personnel or equipment from accidentally coming into contact with the rotating fan blades 3333, providing safety protection. Furthermore, the protective cover 3331 also guides and rectifies the airflow, allowing the air propelled by the fan blades 3333 to flow more smoothly, thus improving the airflow efficiency and effectiveness of the heat sink 333.

[0062] Specifically, in this embodiment, the protective cover 3331 includes an annular shell and protective nets disposed on both sides of the annular shell. The annular shell is disposed on the rotating seat 331, and the protective nets are detachably disposed on the annular shell. The fixed end of the first driving mechanism 3332 is disposed on one of the protective nets.

[0063] For example, the first drive mechanism 3332 is a motor commonly used in the art, and its specific structure and principle are based on the prior art and will not be described in detail here. There are four fan blades 3333, and the four fan blades 3333 are integrated for easy installation; in other embodiments, the number of fan blades 3333 can be set as needed, and no specific limitation is made here.

[0064] Optionally, such as Figure 1 and Figure 3 As shown, the drive structure 4 includes a second drive mechanism 41, a transmission rod 42, a transmission nut 43, and a connecting rod 44. The second drive mechanism 41 is mounted on the support frame 1, and the transmission rod 42 is located at the output end of the second drive mechanism 41 and is rotatably mounted on the support frame 1. The transmission nut 43 is threaded onto the transmission rod 42, and one end of the connecting rod 44 is hinged to the transmission nut 43, while the other end is hinged to the rotating frame 2. Driven by the second drive mechanism 41, the transmission rod 42 can rotate around its own axis. With the threaded engagement between the transmission rod 42 and the transmission nut 43, the transmission nut 43 can move along the extension direction of the transmission rod 42, thereby driving the connecting rod 44 to rotate, which in turn drives the rotating frame 2 to rotate in the horizontal direction, thus achieving the pitch angle adjustment of the heat dissipation structure 3.

[0065] For example, the second drive mechanism 41 is a motor commonly used in the art, and the transmission rod 42 is a lead screw.

[0066] Furthermore, continue to refer to Figure 3The drive structure 4 also includes a reducer 45, which is located at the output end of the second drive mechanism 41, and the transmission rod 42 is located at the output end of the reducer 45. The reducer 45 reduces the output speed of the second drive mechanism 41 while proportionally increasing the output torque according to the reduction ratio, thus optimizing the power characteristics. Specifically, the reducer 45 is a prior art device, and its specific structure and principle are described in the prior art, and will not be repeated here.

[0067] Furthermore, the drive structure 4 also includes a coupling 46, which is located between the output end of the reducer 45 and the transmission rod 42. This makes the installation of the transmission rod 42 more convenient and quick, achieves reliable connection and error compensation, and ensures efficient power transmission to the transmission rod 42. Specifically, the coupling 46 is a prior art device that has been disclosed in the prior art, and its specific structure and principle are the same as those in the prior art, and will not be described in detail here.

[0068] Optionally, such as Figure 1 As shown, the heat dissipation device also includes a control structure 5, which is mounted on the support frame 1. A drive structure 4 is connected to the control structure 5 and is used to control the start and stop of the drive structure 4 to adjust the pitch angle of the heat dissipation structure 3. Specifically, in this embodiment, the control structure 5 is connected to the second drive mechanism 41, and the pitch of the heat dissipation component 333 is adjusted by controlling the start and stop of the second drive mechanism 41.

[0069] Furthermore, the control structure 5 is also connected to the first drive mechanism 3332 and can control the start and stop of the first drive mechanism 3332 and its rotation speed to adjust the rotation and speed of the fan blade 3333.

[0070] Specifically, control structure 5 is a controller that has been disclosed in the prior art. The controller has a control program burned on it. The specific structure of the controller and the related control program are based on the prior art and will not be described in detail here.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
