[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-4A low-voltage cabinet with intelligent heat dissipation function shown in the figure includes a cabinet body 1, a motor 2 is installed on the top of the cabinet body 1, a screw rod 3 is rotatably installed on the relative inner wall of the cabinet body 1, the top of the screw rod 3 is installed on the output shaft of the motor 2, a circular block 4 is threadedly sleeved on the screw rod 3, a fan 5 is installed on the inner wall of the circular block 4, a controller and a sensor 6 are respectively installed on the side and the inner wall of the side of the cabinet body 1, a heat dissipation hole is opened on the side of the cabinet body 1, four fixed blocks 7 are installed on the side of the cabinet body 1, and a threaded rod 8 is rotatably installed on the sides of the two fixed blocks 7 located at the top, the other end of the threaded rod 8 is installed on the knob, and two U-shaped blocks 9 are threadedly sleeved on the threaded rod 8, two circular plates 11 are arranged at the rear of the cabinet body 1, the inner walls of the two circular plates 11 are arranged with filter screens 12, and the two U-shaped blocks 9 are arranged with driven mechanisms for fixing the circular plates 11.

[0024] By means of the above structure, when the temperature is too high, the sensor 6 senses and sends a signal and starts the motor 2 and the fan 5 through the controller. The output of the motor 2 causes the screw rod 3 to rotate, and the rotation of the screw rod 3 causes the circular block 4 to move. The movement of the circular block 4 causes the fan 5 to move. The movement of the fan 5 will dissipate heat to different bottoms, thereby intelligently dissipating heat for the low-voltage cabinet. At this time, the filter 12 filters the dust. When the filter 12 needs to be replaced, the knob is turned, and the rotation of the knob causes the threaded rod 8 to rotate. The rotation of the threaded rod 8 causes the U-shaped block 9 to move. The movement of the U-shaped block 9 causes the circular plate 11 to move. The movement of the circular plate 11 causes the filter 12 to move. At the same time, the movement of the U-shaped block 9 will release the fixation of the circular plate 11 through the driven mechanism, thereby releasing the fixation of the filter 12 when it is not aligned with the heat dissipation hole. At this time, the other filter 12 is at the position of the heat dissipation hole for filtering, thereby avoiding the dust from entering the cabinet due to the vibration when the filter 12 is removed, and avoiding the situation where the heat dissipation hole is exposed for a long time when the filter 12 is replaced, thereby facilitating use.

[0025] like Figure 5 As shown, the driven mechanism includes a movable groove opened on the inner wall relative to the U-shaped block 9, and L-shaped plates 13 are slidably installed on the two movable grooves. Two avoidance holes are opened on the side of the U-shaped block 9, and the sides of the two L-shaped plates 13 respectively penetrate the two avoidance holes and are installed with a first trapezoidal block 15. The sides of the four fixed blocks 7 are installed with a second trapezoidal block 16. The top and bottom of the circular plate 11 are opened with card grooves adapted to the L-shaped plate 13, and the sides of the two L-shaped plates 13 away from each other are provided with elastic units. The advantage of such an arrangement is that the circular plate 11 can be easily fixed or released through the arrangement of the L-shaped plate 13, the first trapezoidal block 15 and the second trapezoidal block 16.

[0026] Specifically, the movement of the U-shaped block 9 will cause the L-shaped plate 13 to move, and the movement of the L-shaped plate 13 will cause the first trapezoidal block 15 to move. When the first trapezoidal block 15 contacts the second trapezoidal block 16, the U-shaped block 9 continues to move to squeeze the first trapezoidal block 15 through the second trapezoidal block 16 to make it rise. The rise of the first trapezoidal block 15 will cause the L-shaped plate 13 to rise, thereby releasing the fixation of the circular plate 11, thereby releasing the fixation while moving the filter screen 12, making it easier to disassemble the filter screen 12.

[0027] like Figure 5 As shown, the elastic unit includes a spring 14 installed on the top of the L-shaped plate 13, and the other end of the spring 14 is installed on the top inner wall of the movable groove. The advantage of this arrangement is that the L-shaped plate 13 can be easily reset through the arrangement of the spring 14.

[0028] Specifically, when the new filter 12 is in the heat dissipation hole, the first trapezoidal block 15 is not in contact with the second trapezoidal block 16, and the L-shaped plate 13 is reset under the action of the spring 14, thereby fixing the circular plate 11, thereby facilitating the installation of the filter 12.

[0029] like Figure 5 As shown, a buffer pad is installed at the bottom of the L-shaped plate 13. The advantage of such an arrangement is that the buffer pad can play a certain buffering role and reduce the vibration generated when the L-shaped plate 13 is reset.

[0030] like Figure 3 As shown, the sides of the two fixed blocks 7 close to each other are jointly installed with a guide rod 10, and the side of the U-shaped block 9 is provided with a guide hole, and the guide rod 10 passes through the guide hole. The advantage of this arrangement is that the U-shaped block 9 can move in the horizontal direction through the setting of the guide rod 10.

[0031] like Figure 4 As shown, a limit rod 18 is installed on the relative inner wall of the cabinet 1, a limit hole is opened on the top of the circular block 4, and the limit rod 18 passes through the limit hole. The advantage of this arrangement is that the limit rod 18 can be set to allow the circular block 4 to move in the horizontal direction.

[0032] like Figure 3 As shown, a fixing threaded hole is provided at the top of one of the fixing blocks 7, and a fixing bolt 17 is installed in the inner thread of the fixing threaded hole. The end of the fixing bolt 17 is tightly pressed against the threaded rod 8. The advantage of such a setting is that the threaded rod 8 can be easily fixed by setting the fixing bolt 17, thereby avoiding the situation in which the threaded rod 8 rotates and causes the filter screen 12 to move during use.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
