Description

Technical Field

[0001] The utility model relates to the field of thermal power plants, in particular to a centralized control and early warning device for thermal power plants. Background Art

[0002] A thermal power plant, also known as a thermal power plant, is a factory that uses coal, oil, and natural gas as fuel to produce electricity. Its basic production process is: the fuel burns in the boiler to heat water to make steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy, and then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] China's authorized patent announcement number: CN 218895193 U records "an auxiliary early warning device for centralized control operation of a thermal power plant". Through the provided clamping assembly, when the early warning device needs to be installed, the mounting plate is first fixed in a suitable position by screws, and then the inner part of the limit plate limit slot is pushed through the buckle slot, and then one side of the second slide slot is aligned with the second slide block, and then slides inward, so that the early warning device can be installed. The above structure avoids the existing installation method of usually fixing it with bolts, but when fixing it, the installer is usually required to lift it up, and a single person cannot install it well, which is not conducive to the installation and use of the early warning device.

[0004] However, there are still the following defects and shortcomings in the application process:

[0005] The card-connecting component is installed in the limit groove by plugging. Although it can realize the installation of the warning device body, its own stability is relatively low. When it is hit by external force, it is easy to slide due to vibration, which may easily cause the warning device body to fall.

[0006] Therefore, it is necessary to provide a new centralized control and early warning device for a thermal power plant to solve the above technical problems. Utility Model Content

[0009] A plug plate is also vertically fixed to one side of the mounting plate, and a plurality of light holes distributed in a straight line are opened on the plug plate;

[0010] A groove is further provided on the back side of the body of the early warning device, and a connecting seat is fixed with screws inside the groove, a slot is provided on one side of the connecting seat, and the plug-in board is plugged into the slot;

[0011] A locking piece is installed inside the connection seat, and the locking piece also extends into the slot and passes through the plug board along the light hole.

[0012] Preferably, a cavity is provided on one side of the connecting seat, a sliding hole connected to the slot is provided on the inner wall of the cavity, and a positioning groove corresponding to the sliding hole is provided on the other side of the slot.
