[0046] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0047] See also Figures 1 to 8 In an embodiment of the present invention, a low-voltage switch cabinet integrated with an all-round and multi-angle heat dissipation structure includes: a switch cabinet body 1, a second gear 10, a power assembly, a transmission assembly and a switching assembly, so that when the electric telescopic rod 30 is actuated, the trigger member 26 can be driven to actuate, and thereby the first gear 9 or the rotating sleeve 16 can be driven to move closer to or away from each other, so that the meshing of the first gear 9 and the second gear 10, and the combination of the first protrusion 1601 and the second protrusion 17 can be performed alternately, and the rotation state of the two sets of impellers 2 can be changed to change the direction of air flowing through the switch cabinet body 1, thereby improving the cooling effect.

[0048] The details are as follows:

[0049] Two sets of impellers 2 are arranged in the switch cabinet body 1;

[0050] The second gear 10 is coaxially connected to the rotating shaft of one set of impellers 2;

[0051] The power assembly is connected to a side plate 3 mounted on the switch cabinet body 1, and a first gear 9 is connected to the power assembly. The first gear 9 cooperates with the second gear 10 to drive the impeller 2 to rotate;

[0052] A slide groove 301 is formed on the side plate 3, a slider 11 is slidably installed in the slide groove 301, and the slider 11 is connected to the rotating shaft of the first gear 9;

[0053] The power assembly includes a driving device 4 installed on the side plate 3, the rotating shaft of the driving device 4 is connected to the rotating shaft of the No. 1 gear 9 through a telescopic connection structure, and the output shaft of the driving device 4 is connected to the transmission assembly through a bevel gear set 12, the telescopic connection structure includes a No. 1 connecting rod 5 rotatably connected to the output shaft of the driving device 4 and a No. 2 connecting rod 6 rotatably connected to the rotating shaft of the No. 1 gear 9, and one end of the No. 1 connecting rod 5 away from the driving device 4 is rotatably connected to one end of the No. 2 connecting rod 6 away from the No. 1 gear 9;

[0054] Two coaxial pulleys are rotatably installed at the rotating connection between the No. 1 connecting rod 5 and the No. 2 connecting rod 6, one of which is connected to the output shaft of the driving device 4 through a No. 1 belt 7, and the other is connected to the rotating shaft of the No. 1 gear 9 through a No. 2 belt 8.

[0055] When in use, the driving device 4 is controlled to work. At this time, the output shaft of the driving device 4 will drive the No. 1 gear 9 to rotate through the No. 1 belt 7 and the No. 2 belt 8, so that when the No. 1 gear 9 is meshed with the No. 2 gear 10, it can drive the No. 2 gear 10 to rotate, thereby driving one group of impellers 2 to rotate.

[0056] The arrangement of the No. 1 connecting rod 5 and the No. 2 connecting rod 6 can keep the No. 1 belt 7 and the No. 2 belt 8 always in a taut state, and the angle between the No. 1 connecting rod 5 and the No. 2 connecting rod 6 can be changed, so that when the slider 11 slides in the slide groove 301 and separates the No. 1 gear 9 from the No. 2 gear 10, the driving device 4 can still drive the No. 1 gear 9 to rotate.

[0057] It should be noted that the above-mentioned No. 1 gear 9, No. 1 belt 7, No. 2 belt 8 and corresponding pulleys should be made of lightweight materials, such as aluminum alloy, plastic steel, etc., to reduce the idle load caused by the continued rotation of the No. 1 gear 9 after the No. 1 gear 9 is separated from the No. 2 gear 10.

[0058] Through the above arrangement, when the driving device 4 is working, the No. 1 gear 9 can always rotate with the driving device 4, and when the No. 1 gear 9 is engaged with the No. 2 gear 10, one group of impellers 2 can be driven to rotate, and when the No. 1 gear 9 is separated from the No. 2 gear 10, the rotating impeller 2 stops rotating.

[0059] See also Figure 4-5 , the transmission assembly is connected to the power assembly, a locking piece is formed on the transmission assembly, and the locking piece is adapted to the second protrusion 17 on the rotating shaft of the other group of impellers 2;

[0060] The transmission assembly includes a transmission rod 13 rotatably mounted on the side plate 3 and connected to the bevel gear set 12, and a transverse plate 18 parallel to the switch cabinet body 1, a rotating sleeve 16 is rotatably mounted on one end of the transverse plate 18, and a plurality of first protrusions 1601 are equidistantly arranged in a circumference in the rotating sleeve 16, and the first protrusion 1601 is adapted to the second protrusion 17;

[0061] The rotating sleeve 16 and the first protrusion 1601 form the locking member;

[0062] The transmission assembly also includes a limiting structure connecting the transmission rod 13 and the follower sleeve 14, the limiting structure includes a follower sleeve 14 rotatably mounted on the other end of the horizontal plate 18, and the follower sleeve 14 is connected to the rotating sleeve 16 through a third belt 15;

[0063] The transmission rod 13 is formed with a limiting groove 1301 along its length direction, and a limiting block 1401 arranged on the inner wall of the follower sleeve 14 is adapted to the limiting groove 1301 .

[0064] When the driving device 4 is working, its output shaft will drive the transmission rod 13 to rotate through the bevel gear set 12. At this time, the follower sleeve 14 will rotate with the transmission rod 13 under the action of the limit groove 1301 and the limit block 1401, thereby rotating the rotating sleeve 16.

[0065] Among them, when the rotating sleeve 16 moves toward the rotating shaft of another group of impellers 2 and makes the No. 1 protrusion 1601 located between two adjacent No. 2 protrusions 17, the No. 1 protrusion 1601 will interfere with the No. 2 protrusion 17. At this time, when the No. 1 protrusion 1601 makes a circular motion, the No. 2 protrusion 17 can drive the other group of impellers 2 to rotate.

[0066] When the rotating sleeve 16 rotates away from the other impeller 2, the first protrusion 1601 will separate from the second protrusion 17. At this time, the second protrusion 17 will lose power, causing the impeller 2 to slowly stop rotating.

[0067] The rotating sleeve 16, the third belt 15, the follower sleeve 14, the transmission rod 13 and the bevel gear set 12 are also preferably made of lightweight materials.

[0068] Through the above arrangement, when the rotating sleeve 16 moves toward or away from the rotating shaft of the impeller 2, the first protrusion 1601 cooperates with the second protrusion 17 to drive the corresponding impeller 2 to rotate or stop.

[0069] See also Figure 6 to Figure 8 The switching component is arranged on the switch cabinet body 1, and the switching component can drive the power component and the transmission component to operate, so that the two groups of impellers 2 rotate alternately.

[0070] A vertical plate 19 is mounted on each of the slider 11 and the horizontal plate 18;

[0071] The switching assembly includes a connecting plate 22 mounted on the switch cabinet body 1, and two vertical grooves 2201 are symmetrically arranged on the connecting plate 22, and groove wheels 21 are arranged in the vertical grooves 2201. The two groove wheels 21 are connected to the vertical plate 19 through the pulling rods 20 respectively;

[0072] The switching assembly further includes an energy storage structure connected to the rotating shaft of the groove wheel 21 and a trigger structure arranged on the switch cabinet body 1, wherein the energy storage structure includes a trigger member 26 connected to the rotating shaft of the groove wheel 21, and the trigger member 26 is a diamond-shaped structure;

[0073] The energy storage structure further includes a fixed sleeve 23 mounted on the switch cabinet body 1, a telescopic shaft 24 is slidably mounted in the fixed sleeve 23, and a pulley 25 is rotatably mounted on one end of the telescopic shaft 24 away from the fixed sleeve 23 and is in rolling contact with the side wall of the trigger member 26;

[0074] A spring is also installed in the fixed sleeve 23, and the spring is connected to the telescopic shaft 24;

[0075] The trigger structure includes an electric telescopic rod 30 installed on the switch cabinet body 1, and a lifting rod 28 is connected to the action end of the electric telescopic rod 30, and the lifting rod 28 is slidably fitted with a connecting sleeve 27 connected to the trigger member 26;

[0076] The lifting rod 28 is provided with two limiting members 29 , and the limiting members 29 are adapted to the connecting sleeve 27 .

[0077] When in use, the electric telescopic rod 30 moves, which will drive the lifting rod 28 connected thereto to move. At this time, the lifting rod 28 will move relative to the connecting sleeve 27. When one of the limit members 29 on the lifting rod 28 abuts against the connecting sleeve 27, the connecting sleeve 27 will drive the trigger member 26 to move. At this time, the side of the trigger member 26 cooperates with the pulley 25, so that the telescopic shaft 24 can move toward the inside of the fixed sleeve 23, compressing the spring and storing elastic potential energy until the pulley 25 moves to a fixed point on the side of the trigger member 26. The spring will release the elastic potential energy and drive the pulley 25 to move along the other side of the same side of the trigger member 26, thereby driving the trigger member 26 to quickly and actively rise or fall, thereby driving the grooved wheel 21 to rise or fall.

[0078] During the process of the groove wheel 21 rising or falling, it can make the number one gear 9 and the rotating sleeve 16 move closer to or away from each other through the pulling rod 20. Specifically, when the two move away from each other, the number one gear 9 can engage with the number two gear 10, so that one group of impellers 2 rotates. At this time, the rotating sleeve 16 is in a state of being away from the rotating shaft of the other group of impellers 2. When the two move closer to each other, the number one gear 9 will separate from the number two gear 10, and the rotating sleeve 16 will move toward the rotating shaft of the other group of impellers 2, so that the number one protrusion 1601 can be located between two adjacent number two protrusions 17, so that the two groups of impellers 2 can switch the rotation state.

[0079] Furthermore, when the two impellers 2 switch the rotation state, the air flow direction in the switch cabinet body 1 can be changed.

[0080] Through the above arrangement, when the electric telescopic rod 30 moves, it can drive the trigger member 26 to move, and thereby drive the No. 1 gear 9 or the rotating sleeve 16 to move closer to or away from each other, so that the meshing of the No. 1 gear 9 and the No. 2 gear 10, and the combination of the No. 1 protrusion 1601 and the No. 2 protrusion 17 can be executed alternately, changing the rotation state of the two sets of impellers 2, so as to change the direction of air flowing through the switch cabinet body 1 and improve the cooling effect.

[0081] A heat dissipation method for a low-voltage switch cabinet integrated with an all-round and multi-angle heat dissipation structure as described above comprises the following steps:

[0082] Step 1: Start the power assembly, which will drive the No. 1 gear 9 to rotate, and at the same time, the power assembly drives the locking part to rotate through the transmission assembly;

[0083] Step 2: When the power component is in motion, the switching component will be driven to move, and the switching component can drive the first gear 9 and the locking member to move closer to or away from each other;

[0084] Step 3: When the first gear 9 is meshed with the second gear 10, one of the impellers 2 will rotate, and the locking member and the second protrusion 17 are in a separated state, so that the other impeller 2 is in a stopped state;

[0085] Step 4: The switching assembly moves, driving the first gear 9 and the second gear 10 to separate, and then the locking member cooperates with the second protrusion 17 to switch the rotation state of the two impellers 2, thereby changing the air flow direction in the switch cabinet body 1.
