DETAILED DESCRIPTION

[0023] like Figure 1 and Figure 2As shown, a virtual power plant power load switching control device in this embodiment includes a housing 1, an input interface 2, an output interface 3, a protection structure 4, and a switching component 5. The input interface 2 is arranged at the top of the housing 1, and the input interface 2 includes two connection ports. The output interface 3 is arranged at the bottom of the housing 1, and both the input interface 2 and the output interface 3 have one end located inside the housing and the other end located outside the housing.

[0024] The protection structure 4 includes a button 41 mounted on the housing 1, a transmission block 42 mounted in the housing 1, a slider 43 connected to the transmission block 42, and a conductive sleeve 45 mounted in the housing 1. The conductive sleeve 45 includes two small sleeves parallel to each other, which are respectively mounted on one end of the input structure 2 located in the housing. Figure 3 As shown, the transmission block 42 is in the shape of a triangular prism, and the transmission block 42 is rotatably installed in the housing 1. One side of the transmission block 42 is in contact with the button 41. A clamping block 46 is provided on the side of the transmission block 42 close to the slider 43. The slider 43 is provided with a clamping groove 47, and the clamping block 46 is clamped in the clamping groove 47. An insulating sleeve 44 is provided on the side of the conductive sleeve 45, and the slider 43 is connected to the insulating sleeve 44. When the button 41 is pressed, the button 41 pushes the transmission block 42 to pull the slider 43 upward, thereby driving the conductive sleeve 45 to slide upward.

[0025] A limit block 49 is also fixedly installed in the housing 1. A protrusion 491 is provided on the limit block 49. A slide groove 48 is provided on the slider 43. When the slider 43 drives the conductive sleeve 45 to slide, the protrusion 491 slides in the slide groove 48, thereby ensuring that the slider 43 slides vertically up and down along the slide groove 48 to prevent the slider from deviating in other directions during the sliding process. A first connecting plate 71 is provided on one side of the top of the limit block 49, and a second connecting plate 72 is provided on one side of the slider 43. One end of the spring 7 is fixed to the connecting plate 71, and the other end of the spring 7 is fixed to the second connecting plate 72. When the button is in the initial position, that is, when the input interface 2 and the output interface 3 are connected, the spring 7 is in a natural state; when the button is pressed, the slider drives the second connecting plate 72 to slide upward, and the spring 7 is compressed. After the button is released, the spring needs to return to its natural state and push the button to assist the button in resetting.

[0026] The switching assembly 5 includes a knob 51 mounted on the housing 1, a metal member 52 mounted in the housing 1, a driven wheel 53, and a driving wheel 54. Figure 4 As shown, three contact feet 521 are provided on the metal part 52, and the three contact feet 521 are evenly distributed along a circle, the driving wheel 54 is connected to the knob 51 and is coaxially arranged, the driven wheel 53 is slidably connected to the housing 1, the driven wheel 53 is meshed with the driving wheel 54, the metal part 52 is fixed to the inner side of the driven wheel 53, and the inner ring of the metal part 52 is provided with a groove for connecting the output interface 3.

[0027] One side of the conductive sleeve 45 is sleeved on one end of the input interface 2 located in the housing 1, the conductive sleeve 45 is located between the input interface 2 and the metal member 52, and the other side of the conductive sleeve 45 is used to connect with the contact pin 521. To further ensure the safety of the switching operation, Figure 5 As shown, the side of the input interface 2 away from the conductive sleeve 45 is provided with an insulating coating 6, and the middle section of the inner wall of the conductive sleeve 45 is also provided with an insulating coating 6. When the conductive sleeve 45 is connected to the input interface 2 and the contact pin 521 at the same time, the conductive sleeve 45 is connected to the side of the input interface 2 that is not sprayed with the insulating coating 6, and the input interface 2 supplies power to the output interface 3; when the conductive sleeve 45 moves upward and separates from the contact pin 521, the exposed side of the input interface 2 contacts the side of the conductive sleeve 45 with the insulating coating 6, thereby cutting off the current on the conductive sleeve 45, ensuring that the conductive sleeve 45 always remains in a power-off state during the switching process.

[0028] By pressing the button 41 , the conductive sleeve 45 slides up and down to connect and disconnect the input interface 2 and the output interface 3 ; by turning the knob 51 , the metal part 52 rotates to change the number of connections between the conductive sleeve 45 and the contact pin 521 .

[0029] The specific method of using the present invention is as follows: when it is necessary to switch the power load, first press the button 41, the button 41 pushes the transmission block 42 to rotate, the transmission block 42 drives the clamping block 46 to lift the slider 43, when the slider 43 moves upward, the limit block 49 limits the slider 43 through the slide groove 48, ensures that the slider 43 moves vertically upward along the slide groove 48, and then the slider 43 drives the insulating sleeve 44 and the conductive sleeve 45 to lift, ensure that the conductive sleeve 45 is separated from the contact pin 521. When the conductive sleeve 45 is separated from the contact pin 521, the exposed side of the input interface 2 contacts the side with the insulating coating 6 inside the conductive sleeve 45, cutting off the current on the conductive sleeve 45. After that, rotate the knob 51, the knob 51 drives the driven wheel 53 to rotate through the driving wheel 54, and the driven wheel 53 drives the metal part 52 to rotate, and adjusts the connection state between the contact pin 521 and the conductive sleeve 45 according to the actual power load state. When the power load is large, both interfaces of the conductive sleeve 45 are connected to the contact pin 521; when the power load is small, only one interface of the conductive sleeve 45 is connected to the contact pin 521. When the adjustment is completed, the button 41 is released, and the transmission block 42 is reset by gravity. At this time, the force on the spring 7 disappears, the spring 7 stretches and resets and pushes the slider 43 downward, so that the automatic conductive sleeve 45 is reconnected with the input interface 2 and the metal part 52, and the power supply is restored.

[0030] The present invention ensures the isolation between the input interface and the output interface during the switching process by setting a protective structure, so that short circuit will not occur during the entire switching process, thereby reducing the safety risk when using the device and improving the safety of the switching device; it also provides a switching component to switch the number of interfaces connected between the input interface and the output interface according to actual needs, thereby improving the flexibility and adaptability of the control device; in addition, the driven wheel is slidably connected to the outer shell, and the metal part is fixedly connected to the driven wheel. This design makes the metal part more stable during the power load switching process, further reducing the safety risk when using the device.
