DETAILED DESCRIPTION

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0017] See also Figure 1-7As shown in the figure, this embodiment provides a power cabinet that is easy to maintain, such as Figure 1-2 As shown, it includes a main body mechanism 1, and a heat dissipation mechanism 3 is fixedly installed inside the main body mechanism 1; Figure 2 As shown, the main body 1 includes a power cabinet 101, and an electrical device 102 is fixedly installed inside the power cabinet 101. Figure 5 As shown, the heat dissipation mechanism 3 includes a heat-conducting enclosure 31 fixedly installed on the top of the electrical device 102, a plurality of metal mesh partitions 32 are fixedly installed on the top of the heat-conducting enclosure 31, a plurality of metal heat-conducting covers 33 are fixedly installed in a vertical state between the plurality of metal mesh partitions 32, and a heat sink 34 is fixedly installed on the top of the metal mesh partition 32. In actual use, the heat-conducting enclosure 31 is used to guide the heat generated by the electrical device 102 during operation to the metal mesh partition 32. After the metal mesh partition 32 absorbs heat, the temperature of the heat-conducting enclosure 31 drops rapidly to avoid heat accumulation in the core area of ​​the electrical device 102, and then the metal mesh partition 32 and the metal heat-conducting cover 33 absorb and store heat to relieve the heat load and ensure the stability of the equipment operating temperature. At the same time, the heat sink 34 dissipates the heat to the surroundings.

[0018] Among them, the interiors of multiple metal heat-conducting covers 33 are set in a hollow state, and the inner cavities of multiple metal heat-conducting covers 33 are filled with paraffin and expanded graphite. The purpose of this setting is that the multiple metal heat-conducting covers 33 divide the interior of the metal mesh partition 32 into multiple independent small cavities. Each small cavity is filled with paraffin and expanded graphite, which effectively prevents the multiple metal heat-conducting covers 33 and the paraffin and expanded graphite inside them from being stratified or moved due to thermal cycles, thereby improving the uniformity of heat transfer and enhancing the overall mechanical strength and stability of the metal mesh partition 32, thereby quickly responding to the heat dissipation needs of different heat source areas and achieving more precise thermal management.

[0019] At the same time, multiple metal mesh partitions 32 are provided with multiple interconnected heat conduction grooves 35 inside, so that during the phase change process of paraffin and expanded graphite inside the metal heat conductive cover 33, the heat absorbed by the multiple metal mesh partitions 32 themselves can flow quickly through the heat conduction grooves 35 and diffuse to the heat sink 34.

[0020] Furthermore, a plurality of guide grooves 36 are provided on the top of the heat sink 34 to increase the heat dissipation area on the surface of the heat sink 34. By cooperating with the photovoltaic mechanism 2, external cooling water is utilized and guided to flow through the guide grooves 36, so that the evaporative cooling effect of the cooling water on the surface of the heat sink 34 can further improve the heat dissipation efficiency.

[0021] Further, refer to Figure 2-3As shown, a photovoltaic mechanism 2 is fixedly installed on the top of the main mechanism 1, and the photovoltaic mechanism 2 includes a supporting baffle 21 fixedly installed on the top of the power cabinet 101, and a liquid storage cover 22 for storing cooling water is fixedly installed on the top of the supporting baffle 21. The top of the liquid storage cover 22 is open, and a plurality of photovoltaic support plates 23 for installing photovoltaic panels are hinged on the top of the liquid storage cover 22. An elastic waterproof belt can be fixedly connected between the plurality of photovoltaic support plates 23, and the plurality of photovoltaic support plates 23 are in an inclined state under normal conditions and are spliced ​​and enclosed in a conical shape to cover the top of the liquid storage cover 22. At the same time, an electric reciprocating screw 24 is rotatably installed at the vertical center line position of the liquid storage cover 22, and the outer wall of the electric reciprocating screw 24 is engaged with an internal threaded connecting sleeve 25 hinged to the plurality of photovoltaic support plates 23, and a waterproof driving motor can be arranged below the electric reciprocating screw 24; Figure 3 and Figure 5 As shown, a one-way flow plate 26 rotatably connected to the electric reciprocating screw 24 is fixedly installed inside the liquid storage cover 22, and a guide pipe 37 connected to the one-way flow plate 26 is provided at the bottom of the liquid storage cover 22. A plurality of pressure-type one-way valves can be provided at the connection between the one-way flow plate 26 and the guide pipe 37. When the cooling water in the liquid storage cover 22 generates a pressure exceeding a threshold value on the pressure-type one-way valve, the cooling water can flow into the guide pipe 37 through the one-way flow plate 26, and the guide pipe 37 penetrates the power cabinet 101 and extends to above the guide groove 36 of the heat sink 34.

[0022] It can be understood that in actual use, the user can first install the photovoltaic panel on the photovoltaic support panel 23, and under normal conditions, multiple photovoltaic support panels 23 are tilted away from one side of the liquid storage cover 22, so that multiple photovoltaic support panels 23 and photovoltaic panels are in an inverted funnel shape and cover the top of the liquid storage cover 22, so that the photovoltaic panel can receive light from all directions, thereby improving the photoelectric conversion efficiency of the photovoltaic panel, and a part of the electricity generated by the photovoltaic panel can be used to drive the motor, etc.; secondly, by starting the electric reciprocating screw 24 to rotate, the internal threaded connecting sleeve 25 can drive the multiple photovoltaic support panels 23 and the hinged end of the internal threaded connecting sleeve 25 to move up and down, thereby changing the inclination angle of the multiple photovoltaic support panels 23 and the photovoltaic panel. Under normal conditions, the internal threaded connection sleeve 25 drives the photovoltaic support plate 23 to be set at a side position of the electric reciprocating screw 24 away from the one-way circulation plate 26. At this time, the multiple photovoltaic support plates 23 and the photovoltaic panels are in an inverted funnel shape, which is convenient for receiving light. When the electric reciprocating screw 24 is driven to rotate so that the internal threaded connection sleeve 25 drives the multiple photovoltaic support plates 23 to gradually tilt downward, the space between the liquid storage cover 22 and the photovoltaic support plate 23 begins to decrease, and then the cooling water stored between the liquid storage cover 22 and the photovoltaic support plate 23 begins to be squeezed. When the pressure of the cooling water on the one-way circulation plate 26 reaches the threshold, the cooling water can enter the inner cavity of the guide pipe 37 after the one-way circulation plate 26 and fall to the heat sink 3 4, so that the cooling water circulates in the channel of the guide groove 36, greatly improving the heat dissipation efficiency; preferably, a plurality of fine holes can be provided on the photovoltaic support plate 23, and in the process of the electric reciprocating screw 24 driving the photovoltaic support plate 23 to move downward, the speed at which the air or cooling water passes through the fine holes is slow, so as to avoid affecting the pressure of the cooling water on the one-way circulation plate 26 during the downward movement and failing to reach the threshold; at the same time, when the electric reciprocating screw 24 is driven to rotate so that the internal threaded connection sleeve 25 is located above the bottom one-way circulation plate 26, the photovoltaic support plate 23 and the photovoltaic panel are in an upright funnel shape, and part of the cooling water can pass through the fine holes and remain in the funnel-shaped bottom formed by the photovoltaic support plate 23 and the photovoltaic panel. At this time, the electric reciprocating screw The rod 24 drives multiple photovoltaic support panels 23 to move upward gradually through the internal threaded connecting sleeve 25, and the photovoltaic support panel 23 and the photovoltaic panel begin to gradually tilt outward. In this process, the retained cooling water flows from the photovoltaic support panel 23 and the photovoltaic panel close to the end of the electric reciprocating screw 24 to the bottom, and the dust attached to the photovoltaic panel is taken off, thereby improving the cleanliness of the surface of the photovoltaic panel and greatly improving the photoelectric conversion efficiency; in addition, when encountering rainy weather, the photovoltaic panel cannot perform efficient photoelectric conversion work, and the internal threaded connecting sleeve 25 can be driven to a lower position, so that the photovoltaic support panel 23 can better receive part of the rainwater, and this part of the rainwater will slowly fall into the liquid storage cover 22 through the small holes, thereby supplementing the cooling water.

[0023] Further, refer to Figure 4As shown, the outer walls of multiple photovoltaic support panels 23 are rotatably installed with elastic connecting rings 27, the inner wall of the liquid storage cover 22 is provided with a first guide slot 28, the inner cavities of multiple first guide slots 28 are slidably installed with directional connecting plates 29 hinged to the elastic connecting ring 27, and one side of multiple directional connecting plates 29 is fixedly installed with a first telescopic spring 210 fixedly connected to the first guide slot 28. In actual use, as the photovoltaic support panel 23 is tilted and adjusted, the directional connecting plate 29 can be telescopically moved in the inner cavity of the first guide slot 28 to avoid affecting the flexibility of the photovoltaic support panel 23 during tilt adjustment.

[0024] It is understandable that in actual use, as the photovoltaic support panel 23 is tilted and adjusted, the directional connection plate 29 can be telescopically moved in the inner cavity of the first guide slot 28, thereby improving the flexibility of the photovoltaic support panel 23 during tilt adjustment and avoiding damage to the photovoltaic panel.

[0025] Further preferably, a connecting rod 38 fixedly connected to the electric reciprocating screw 24 is installed in the guide tube 37, two limit slide bars 39 are fixedly installed on the guide tube 37, a directional sliding sleeve 310 is slidably installed on the limit slide bar 39, a guide frame 311 is fixedly installed at the bottom of the directional sliding sleeve 310, a second telescopic spring 313 is fixedly installed between the directional sliding sleeve 310 and the guide tube 37, and a special-shaped guide plate 312 is fixedly installed at the bottom of the connecting rod 38, and the special-shaped guide plate 312 matches the connecting rod 38.

[0026] A drainage pipe 317 communicating with the guide groove 36 is fixedly mounted on one side of the heat dissipation plate 34 , and one side of the drainage pipe 317 extends out of the power cabinet 101 .

[0027] Specifically, referring to Figure 5 and Figure 7As shown, the inner cavity of the guide tube 37 is rotatably installed with a connecting rod 38 fixedly connected to the electric reciprocating screw 24, the outer wall of the guide tube 37 is fixedly installed with two limit slide bars 39, the outer walls of the two limit slide bars 39 are slidably installed with directional sliding sleeves 310, the bottoms of the two directional sliding sleeves 310 are fixedly installed with guide frames 311, a second telescopic spring 313 is fixedly installed between the directional sliding sleeves 310 and the guide tube 37, and a special-shaped guide plate 312 is fixedly installed at the bottom of the connecting rod 38. In actual use, the guide frame 311 can slide on the surface of the heat sink 34 along the horizontal trajectory of the two limit slide bars 39 through the directional sliding sleeves 310, so that when the cooling water passes through the guide tube When the tube 37 falls into the guide frame 311 and onto the surface of the heat sink 34, the guide frame 311 can be moved back and forth to push the cooling water to move on the surface of the heat sink 34, thereby increasing the contact range between the cooling water and the surface of the heat sink 34 and avoiding the problem of ineffective diffusion that affects the overall heat dissipation efficiency of the heat sink 34; when the connecting rod 38 rotates synchronously with the electric reciprocating screw 24 and drives the special-shaped guide plate 312 to rotate, the more protruding side of the special-shaped guide plate 312 contacts the horizontal inner wall of the guide frame 311 and pushes the guide frame 311 to move horizontally. In this reciprocating manner, the guide frame 311 can be moved back and forth horizontally on the surface of the heat sink 34.

[0028] At the same time, a drain pipe 317 connected to the guide groove 36 is fixedly installed on one side of the heat sink 34, and one side of the drain pipe 317 extends out of the outer wall of the power cabinet 101. The purpose of this arrangement is to allow the cooling water to flow through the surface of the heat sink 34, and then flow through the inner cavity of the guide groove 36, and flow to the guide pipe 37 to be discharged from the inner cavity of the power cabinet 101, thereby avoiding the problem of excess cooling water accumulating in the inner cavity of the power cabinet 101 for a long time, causing the inner cavity of the power cabinet 101 to be too humid.

[0029] Optionally, as another implementation, refer to Figure 7The second guide slot 314 is fixedly installed on one side of the special-shaped guide plate 312, and a directional sliding support rod 315 is slidably installed in the inner cavity of the second guide slot 314. One end of the directional sliding support rod 315 is fixedly installed with a third telescopic spring 316 fixedly connected to the second guide slot 314, wherein the length of the directional sliding support rod 315 is consistent with the radius length of the side of the special-shaped guide plate 312 provided with the second guide slot 314. Under normal conditions, the third telescopic spring 316 is in an expanded state to push the directional sliding support rod 315 out of the inner cavity of the second guide slot 314. When the connecting rod 38 rotates synchronously with the electric reciprocating screw 24, the special-shaped guide plate 312 is driven to rotate. During rotational movement, as one side of the shaped guide plate 312 provided with the directional sliding rod 315 contacts the horizontal inner wall of the guide frame 311, the directional sliding rod 315 is pressed and retracted into the inner cavity of the second guide slot 314. When the one side of the shaped guide plate 312 provided with the directional sliding rod 315 gradually rotates toward the side of the vertical inner wall of the guide frame 311, the directional sliding rod 315 loses its restraint and is pushed outward by the elastic restoring force of the third telescopic spring 316, thereby synchronously pushing the guide frame 311 close to the side of the directional sliding rod 315 to translate in the same direction. In this reciprocating manner, the guide frame 311 can be reciprocated on the surface of the heat sink 34.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
