[0003] In photovoltaic power generation, solar cells generate direct current under sunlight, and the battery also stores direct current.

[0040] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0044] Example 1

[0045] Reference Figure 1 , provides a schematic diagram of the overall structure of a multi-angle cooling fan and a heat dissipation inverter, such as Figure 1-6 , a multi-angle heat dissipation fan, comprising:

[0046] The fan component 100 includes an air outlet mechanism 101 and a mounting mechanism 102 disposed above the air outlet mechanism 101. The air outlet mechanism 101 and the mounting mechanism 102 are transmitted via a multi-directional transmission mechanism 103.

[0047] The air outlet mechanism 101 comprises a circular ring 101a, an inner frame 101b is fixed on the upper surface of the circular ring 101a, a transmission shaft 101c vertically penetrates the axis of the upper surface of the inner frame 101b, and a fan blade 101d is sleeved and fixed on the transmission shaft 101c located inside the circular ring 101a.

[0048] Specifically, the fan blade 101d is located below the circular ring 101a, so that when the fan blade 101d and the circular ring 101a rotate at the same time, the air circulation is not affected by the obstruction of the circular ring 101a, thereby ensuring the wind force generated by the rotation of the fan blade 101d.

[0049] Furthermore, the mounting mechanism 102 includes a fixing ring 102a, and vertical plates 102b are symmetrically fixed on the upper surface of the fixing ring 102a, and fixing ears 102c are fixed on one side of the upper ends of the two vertical plates 102b;

[0050] Specifically, the fixing ear 102c is provided with a mounting hole, which can be easily installed by bolts.

[0051] A mounting plate 102d is disposed inside the fixing ring 102a, and the mounting plate 102d is fixedly connected to the fixing ring 102a via a fixing rod 102e.

[0052] Furthermore, the multi-directional transmission mechanism 103 includes a driving assembly 103a and an angle adjustment assembly 103b. The driving assembly 103a is fixed to the upper surface of the mounting plate 102d to drive the fan blades 101d to rotate, and the angle adjustment assembly 103b connects the inner frame 101b and the driving assembly 103a.

[0053] Furthermore, the driving assembly 103a includes a driving motor 103a-1 installed on the upper surface of the mounting plate 102d, a transmission shaft 103a-2 fixedly connected to the transmission end of the driving motor 103a-1, and a universal coupling 103a-3. The universal coupling 103a-3 is used to connect the transmission shaft 103a-2 with both ends of the transmission shaft 1 101c. The operation of the driving motor 103a-1 drives the transmission shaft 103a-2 to rotate, and the transmission of the universal coupling 103a-3 drives the transmission shaft 1 101c to rotate. The rotation of the transmission shaft 101c drives the fan blades 101d to rotate to generate airflow to form wind.

[0054] Furthermore, the angle adjustment assembly 103b includes a fixed block 103b-1 and a worm gear 103b-2 which is sleeved and fixed on the outside of the second transmission shaft 103a-2. One end of the fixed block 103b-1 is penetrated by a through hole 103b-3 for the second transmission shaft 103a-2 to pass through, and the other end of the fixed block 103b-1 is rotatably connected to a linkage rod 103b-4. Both sides of the linkage rod 103b-4 are rotatably connected at the bottom end with swing blocks 103b-5.

[0055] Specifically, both ends of the through hole 103b-3 are welded and fixed to the second transmission shaft 103a-2, so that the fixed block 103b-1 can be fixed on the second transmission shaft 103a-2, and the fixed block 103b-1 is driven to rotate synchronously when the second transmission shaft 103a-2 rotates.

[0056] Furthermore, a connecting plate 103b-6 is fixed to the bottom of the fixed block 103b-1, and a worm wheel 103b-7 meshing with the worm 103b-2 is arranged on the inner side of the connecting plate 103b-6, and a rotating shaft 103b-8 is fixed through the axis of the worm wheel 103b-7, and both ends of the rotating shaft 103b-8 respectively pass through the connecting plate 103b-6 and are fixed with an eccentric rod 103b-9, and the other end of the eccentric rod 103b-9 is rotatably connected to the end of the swing block 103b-5, and a fixed seat 103b-10 connected to the inner frame 101b is fixed to the bottom of the swing block 103b-5.

[0057] Specifically, the worm 103b-2 rotates with the rotation of the second transmission shaft 103a-2, and due to the meshing relationship, the worm wheel 103b-7 rotates accordingly. After the worm wheel 103b-7 rotates, the eccentric rod 103b-9 is driven to rotate. The eccentric rod 103b-9 rotates and drives the swing block 103b-5 to move. When one end of the eccentric rod 103b-9 faces the nine o'clock direction of the worm wheel 103b-7 (the worm wheel 103b-7 is regarded as a clock face), the eccentric rod 103b-9 is horizontal and the linkage rod 103b-4 is vertical. When one end of the eccentric rod 103b-9 faces the three o'clock direction of the worm wheel 103b-7, the eccentric rod 103b-9 is also horizontal, and the linkage rod 103b-4 is tilted outward.

[0058] When the eccentric rod 103b-9 swings from the nine o'clock direction to the three o'clock direction, the swing block 103b-5 always remains horizontal and moves up and down with the eccentric rod 103b-9. Because the length of the swing block 103b-5 is fixed, it will push the linkage rod 103b-4 during the movement to the three o'clock direction. The linkage rod 103b-4 is pushed back and tilted. When one end of the swing block 103b-5 is displaced to the three o'clock direction, the inclination angle of the linkage rod 103b-4 is the largest. Since the bottom end of the linkage rod 103b-4 is horizontal with the axis of the worm gear 103b-7, it can ensure that the swing block 103b-5 can be kept horizontal at the three o'clock or nine o'clock direction.

[0059] When the eccentric rod 103b-9 moves from three o'clock to nine o'clock, due to the limited length of the linkage rod 103b-4, the swing block 103b-5 can only be forced to tilt along the rotation direction of the eccentric rod 103b-9. At the same time, the linkage rod 103b-4 changes from an inclined state to a vertical state. Therefore, the movement of the swing block 103b-5 from the inclined state to the horizontal state will drive the ring 101a to move synchronously, thereby changing the wind direction of the fan blade 101d. The fixed block 103b-1 will rotate with the ring 101a, so the tilt direction of the swing block 103b-5 is also changed. Combined with the action, the conical swing amplitude of the fan blade 101d can increase the wind direction area through the conical swing amplitude, accelerate the air flow rate in the area, and further improve the heat dissipation effect.

[0060] Operation process: During the heat dissipation process, the driving motor 103a-1 operates to drive the transmission shaft 2 103a-2 to rotate, and the transmission shaft 1 101c is driven to rotate through the transmission of the universal coupling 103a-3, and the rotation of the transmission shaft 101c drives the fan blades 101d to rotate to generate airflow and form wind;

[0061] The worm 103b-2 rotates with the rotation of the transmission shaft 103a-2. Due to the meshing relationship, the worm wheel 103b-7 rotates accordingly. After the worm wheel 103b-7 rotates, it drives the eccentric rod 103b-9 to rotate. The eccentric rod 103b-9 rotates and drives the swing block 103b-5 to move. The movement of the swing block 103b-5 from tilting to horizontal will drive the ring 101a to move synchronously, thereby changing the wind direction of the fan blade 101d. The fixed block 103b-1 will rotate with the ring 101a, so the tilt direction of the swing block 103b-5 is also changed. Combined with the action, the conical swing amplitude of the fan blade 101d is increased through the conical swing amplitude to increase the wind direction area, accelerate the air flow rate in the area, and further improve the heat dissipation effect.

[0062] Example 2

[0063] Reference Figure 7, this embodiment is different from the first embodiment in that: this embodiment also includes:

[0064] The weeding component 200 is installed at the bottom of the transmission shaft 101c for cutting weeds.

[0065] Furthermore, the weeding component 200 includes a disc 201 fixed to the bottom end of the transmission shaft 101c, and the outer circumference of the disc 201 is symmetrically provided with notches 202, and a fixing column 203 is fixed on the inner side of the notch 202, and a weeding rope 204 is tied to the fixing column 203.

[0066] Specifically, the weed rope 204 is woven from nylon wire and soft steel wire, has high strength and toughness, and can more easily break the branches of weeds under the centrifugal effect, thereby inhibiting their growth.

[0067] The rest of the structure is the same as that of Example 1.

[0068] Operation process: the disc 201 rotates with the rotation of the transmission shaft 101c, and during the rotation process, the weed rope 204 rotates and generates centrifugal force. When the branches of the weeds grow high and reach the striking area of ​​the weed rope 204, they will be broken by the weed rope 204, inhibiting their growth trend, thereby effectively solving the problem that excessive weeds in mountainous areas can easily cause damage to the radiator, reducing unnecessary cost waste, and ensuring the heat dissipation performance of the radiator.

[0069] Example 3

[0070] Reference Figure 8-9 , this embodiment is different from the above embodiment in that: this embodiment discloses a heat dissipation inverter, including the above multi-angle heat dissipation fan, and also includes:

[0071] Inverter body 300;

[0072] The heat dissipation component 400 is installed at the bottom of the inverter body 300 to dissipate heat and cool the inverter body 300.

[0073] Furthermore, the heat dissipation component 400 includes a heat dissipation fan 401 and a water-cooled heat dissipation assembly 402 . The heat dissipation fan 401 is embedded and installed in the inner bottom of the inverter body 300 .

[0074] Furthermore, the water-cooled heat dissipation component 402 includes a heat conductive plate 402a installed at the bottom of the inverter body 300, a heat dissipation fin 402b is fixed to the bottom of the heat conductive plate 402a, a water cooling pipe 402c is installed through the middle section of the heat dissipation fin 402b, and the two ends of the water cooling pipe 402c are respectively a water inlet 402d and a water return port 402e.

[0075] Specifically, the heat conducting plate 402a and the heat dissipating fins 402b are both made of red copper, which has high thermal conductivity and can quickly absorb the temperature of the inverter body 300, and effectively reduce the temperature of the inverter body 300 by heat exchange.

[0076] The rest of the structure is the same as that of Example 2.

[0077] Operation process: When cooling, the heat dissipation fan 401 draws out the heat in the inverter body 300 through negative pressure, ensuring that the heat emitted from the inner space of the inverter body 300 is dissipated. At the same time, the heat conduction plate 402a and the heat dissipation fins 402b are both made of red copper, which has high thermal conductivity and can quickly absorb the temperature of the inverter body 300, and effectively reduce the temperature of the inverter body 300 by heat exchange;

[0078] The water inlet 402d and the water return port 402e are connected to water sources through water pipes respectively. A water pump is installed on the water pipe connected to the water inlet 402d. The water pump draws water in. After the water is drawn in, the cold water enters the water cooling pipe 402c. The water cooling pipe 402c is coiled in the heat dissipation fin 402b, and then heat is exchanged with the heat on the heat dissipation fin 402b, so that the temperature on the surface of the heat dissipation fin 402b is quickly reduced, thereby achieving a high efficiency heat dissipation rate of the heat dissipation fin 402b. The warm water after heat exchange will return from the water return port 402e to form a cycle;

[0079] This structure uses water cooling and wind power to dissipate heat simultaneously, which maximizes the heat dissipation efficiency, ensures that the temperature of the inverter body 300 can be quickly reduced and maintained at a low temperature, and makes the inverter body 300 operate at a lower temperature, thereby maximizing the conversion efficiency of the inverter body 300 and reducing power waste.
