Direct current screen with adjustable function

Abstract

The invention relates to the technical field of direct-current screens, in particular to a function-adjustable direct-current screen which comprises a direct-current screen body, a plurality of buffer blocks are fixedly connected to the two sides of the direct-current screen body, protective shells are fixedly connected to the two sides of each buffer block, a machine shell is fixedly connected to the upper ends of the protective shells, and the protective shells are fixedly connected to the lower ends of the machine shell. A motor is fixedly connected to the interior of the machine shell, fan blades are fixedly connected to the end of an output shaft of the motor, a fan blade support is further fixedly connected to the upper end of the protective shell, a protective door is rotationally connected to the outer wall of the protective shell, and an observation window is formed in the protective door. The rotating angle of the baffle in the empty groove can be controlled by rotating the knob through cooperation of the worm gear and the worm, so that the flow rate of air circulation in the equipment is adjusted, the heat dissipation efficiency is further controlled, the equipment can be changed according to the surrounding environment, the use stability of the direct-current screen is improved, and the service life of the direct-current screen is prolonged. And the service life of the equipment is long.

Description

technical field [0001] The invention relates to the technical field of DC panels, in particular to a DC panel with adjustable functions. Background technique [0002] The function of the DC screen is to connect the AC power supply to test whether the AC dual power switching device works normally, and whether the voltage of the lower port of the dual power switching device is normal. After the test of the AC part is normal, close the AC switch of the charging module in turn to observe whether the module starts normally and measure the output voltage and polarity of the module. After the charging module starts normally and the output voltage and polarity are correct, turn on the battery pack switch and each busbar switch, measure whether the voltage and polarity of the lower port of the battery pack switch, the closing busbar, and the control busbar are correct, and observe whether the direction of the voltmeter is turned on. On the contrary, because there are too many electr...

Problems solved by technology

[0006] According to the existing technology, fans are installed to dissipate heat inside the DC screen, but the heat dissipation components lack a structure that can adjust the heat dissipation intensity. Due to the different seasons throughout the year, the temperature and humidity of the working environment around the DC screen are always changing. For this reason, the above-mentioned equipment cannot adjust the intensity of heat dissipation in different weathers so as to provide a suitable working environment for the DC screen, and most of the DC screens are installed inside the factory, and there is floating dust in the air. When the DC screen performs air circulation, Particles in the air will float to the inside of the device, causing damage to the device. The invention provides a DC screen with adjustable functions
