[0039] Embodiment Two

[0040] Please refer to Figures 1-11

[0041] ​The outer surface of the water tank 307 is fixedly connected with a reinforcement frame 16. The front surface of the reinforcement frame 16 is fixedly connected with the back surface of the outer shell 1. Through the reinforcement frame 16, the water tank 307 and the outer shell 1 can be reinforced to prevent their positions from shifting during operation;

[0042] The outer surface of the water pump 306 is fixedly connected with a fixing frame 12. The upper surface of the fixing frame 12 is fixedly connected with the bottom surface of the heat conduction plate 304. Through the fixing frame 12, the water pump 306 and the heat conduction plate 304 can be fixed to prevent them from shaking and shifting during operation;

[0043] The outer surface of the condensate water pipe 305 is fixedly connected with four fixing blocks 13. The upper surface of each group of fixing blocks 13 is fixedly connected with the bottom surface of the heat conduction plate 304. Through the fixing blocks 13, the position of the condensate water pipe 305 can be fixed to prevent its position from shifting during use;

[0044] The bottom surface of the outer shell 1 is fixedly connected with a bottom plate 5. The bottom surface of the bottom plate 5 is fixedly connected with a number of identical anti-slip bases 15. The outer surfaces of each group of anti-slip bases 15 are jointly fixedly connected with a limiting block 14. The upper surface of each group of limiting blocks 14 is fixedly connected with the bottom surface of the bottom plate 5. Through the anti-slip bases 15, the device can be stably supported to prevent its position from shifting during operation. Through the limiting blocks 14, the position of the anti-slip bases 15 can be restricted to prevent them from shaking during use;

[0045] A rubber plug 11 is clamped inside the water tank 307. The outer surface of the heat dissipation pipe 301 is fixedly connected with the inner wall of the outer shell 1. Through the rubber plug 11, the condensate water inside the water tank 307 can be protected from external pollution.

[0046] The specific implementation of this embodiment is as follows: First, take out the rubber plug 11 from the water tank 307, and then add sufficient condensed water to the water tank 307. When the voltage acquisition device generates a high temperature during long-term use, by rotating the brushless fan 302, external air can pass through the filter plate 303 and enter the housing 1, thereby cooling and dissipating heat from the voltage acquisition device. The brushless fan 302 has a small friction and low noise during operation, providing a more comfortable user experience. Moreover, the brushless fan 302 eliminates the carbon brush, reduces wearing parts, has a longer service life, reduces the costs of maintenance and replacement. In addition, the motor of the brushless fan 302 runs at a high speed and can generate a larger air volume at the same power. The filter plate 303 can block dust and other impurities in the external air, effectively avoiding the problem that dust and impurities enter the voltage acquisition device and damage its internal components. The high temperature generated by the voltage acquisition device can be transferred to the heat conduction plate 304, and then to the condensed water pipe 305 on the heat conduction plate 304. The condensed liquid in the water tank 307 is transported to the condensed water pipe 305 through the output end of the water pump 306, which can cool and dissipate heat from the heat conduction plate 304. Thus, the voltage acquisition device can be cooled and dissipated, enabling it to work stably in extreme environments such as high temperature and dust. The heat conduction plate 304 can help with uniform heating, making the distribution of the heat source uniform, distributing heat evenly, ensuring that all parts of the condensed water pipe 305 can be fully heated, and effectively improving the acquisition accuracy of the device.

[0047] Embodiment Three

[0048] Please refer to Figures 1-11, the specific implementation of this embodiment is as follows: First, place the entire device in a safe area. Then, open the cover plate 4 by using the handle 9, and thus it is possible to collect voltage. By pushing the pull handle 207, the sliding plate 203 is driven to slide in the chute 206. Then, pass the connecting wire through the limiting frame 205 to facilitate restricting the position of the connecting wire and achieve the purpose of fixed limiting. Then, connect it to the voltage acquisition main body 201, and multiple sets of connection terminals are provided, which can be applied to test on energy storage converters, photovoltaic inverters, power electronic transformers, and energy routers, solving the disadvantages that some power analyzers and data acquisition devices are limited in their own voltage acquisition and cannot test high voltages. This device can simultaneously collect multiple voltage signals, facilitating the collection of multiple voltages and enhancing the use effect of the device. When external power supply is required, press the rotating shell 208 to make the clamping block 213 inside the rotating shell 208 enter the groove 212 on the rotating protection cover 211. Then, twist the rotating shell 208, which can drive the rotating protection cover 211 to rotate, and thus it can be taken out from the protection shell 209, so that the external power supply can be connected to facilitate voltage testing. When the voltage acquisition is completed, just push the pull handle 207, and the sliding plate 203 can move in the protective shell 202, thereby protecting the device and effectively preventing it from being interfered by the outside world. By pressing and twisting the rotating shell 208 to drive the rotating protection cover 211 to rotate, it can be installed on the protection shell 209, thereby protecting the external power supply socket 210 and preventing it from being damaged by the outside world, effectively avoiding the problems that the voltage acquisition device cannot ensure safety and reliability, the acquisition accuracy cannot meet the test requirements, the error is large, a voltage divider can only collect one-way voltage, and when testing, the voltage divider requires a separate external power supply, and when using a power analyzer for supporting testing, there is no dedicated test line and an adapter cable needs to be used, resulting in cumbersome wiring. Take out the rubber plug 11 from the water tank 307, and then add sufficient condensed water to the water tank 307. When the voltage acquisition device generates a relatively high temperature during long-term use, by rotating the brushless fan 302, the outside air can pass through the filter plate 303 and enter the housing 1, thereby cooling and dissipating heat from the voltage acquisition device. The brushless fan 302 has small friction and low noise during operation, providing a more comfortable use experience. Moreover, the brushless fan 302 eliminates the carbon brush, reduces the wearing parts, has a longer service life, reduces the maintenance and replacement costs, and the motor of the brushless fan 302 runs at a high speed, capable of generating a larger air volume under the same power. The filter plate 303 can block dust and other impurities in the outside air, effectively avoiding the problem that dust and impurities enter the voltage acquisition device and damage its internal components. And the relatively high temperature generated by the voltage acquisition device can be transferred to the heat conduction plate 304, and then to the condensed water pipe 305 on the heat conduction plate 304,The condensate in the water tank 307 is transported to the condensate water pipe 305 through the output end of the water pump 306, which can cool down and dissipate heat from the heat conduction plate 304. Thus, the voltage acquisition device can be cooled and heat-dissipated, enabling the voltage acquisition device to operate stably in extreme environments such as high-temperature dust. The heat conduction plate 304 can help with uniform heating, making the distribution of the heat source uniform, capable of evenly distributing heat, ensuring that all parts of the condensate water pipe 305 can be fully heated, and effectively improving the acquisition accuracy of the device.
