[0002] The flue gas denitrification device (SCR) is an important environmental protection facility in major thermal power plants. It removes NOX from flue gas by spraying ammonia and catalyst. In actual operation, the control of ammonia spraying will directly affect the efficiency of denitrification, affect the emission of NOX and escaped ammonia, and affect the service life of the catalyst, thus affecting the overall energy consumption cost of denitrification operation. Therefore, how to reasonably adjust and control ammonia spraying is an important issue that every SCR user is concerned about, so the power plant external control device has appeared.
[0003] However, the existing external control devices of power plants are generally directly mounted outside. Due to the harsh environment and heavy dust in power plants, the wiring ports on the external control devices of power plants are easily contaminated by dust when not in use, resulting in poor contact when used again, affecting the use effect. Therefore, an external control device of a power plant with adjustable energy consumption is proposed. Utility Model Content

When it is necessary to connect the wiring to the control device body, the staff lifts the protective plate upward with their hands to rotate the protective plate to a horizontal state through the rotating shaft, and then pulls the T-shaped rod to stretch the spring. When the position of the T-shaped rod and the socket are aligned, the external force on the T-shaped rod is released, and the end of the T-shaped rod is inserted into the socket under the elastic force of the spring. At this time, the horizontal position of the protective plate can be fixed, which is convenient for connecting the wiring to the wiring port of the control device body for coordinated use.
[0015] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model is not only convenient for hanging and use, but also can adjust the energy consumption and reduce the cost investment. In addition, it has a protective structure to avoid contamination of the wiring port of the control device body and cause poor contact. BRIEF DESCRIPTION OF THE DRAWINGS
