Description

Technical Field

[0002] Thermal power plants, also known as thermal power plants for short, are plants that use combustibles as fuel to produce electricity. The basic production process is: when the fuel is burned, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the steam turbine to rotate, converting the thermal energy into mechanical energy. The steam turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. The prime mover is usually a steam engine or a gas turbine. In some smaller power stations, internal combustion engines may also be used. They all generate electricity by using the pressure drop in the process of high-temperature, high-pressure steam or gas passing through a turbine to become low-pressure air or condensed water.

After the cabinet 1 is raised, the sealing plug 82 at the upper end of the cushion block 81 is separated from the air inlet 41, and then the fan 33 at the upper end of the bracket 32 ​​drives the air flow inside the cabinet 1, so that the exhaust assembly 3 can discharge the hot air and moisture inside the cabinet 1, so that fresh air enters the cabinet 1 through the air inlet 41, and prevents external dust and other impurities from entering the cabinet 1 through the filter 43. By observing the temperature sensor 13 and humidity sensor 14, after the temperature and humidity inside the cabinet 1 are reduced, turn off the heater 2 and the exhaust assembly 3, then reset the cabinet 1 through the lifting mechanism 6, and use the cushion block 81 to buffer the cabinet 1 to prevent damage to the cabinet 1, and at the same time insert the sealing plug 82 into the air inlet 41, so that the closing assembly 8 plays the role of sealing the air inlet mechanism 4, preventing moisture and liquid from entering the cabinet 1 through the air inlet 41, and using the rain shield 9 to prevent rainwater and other foreign matter from entering the cabinet 1 through the exhaust port 31, so that the interior of the cabinet 1 can be kept dry, and at the same time, damage to electronic components caused by excessive temperature can be avoided, and moisture remaining in the cabinet 1 can be avoided to affect the electronic components, thereby achieving moisture-proof. The function is to replace the filter 43, and when the filter 43 needs to be replaced, the bolt 452 is separated from the first threaded groove 453, so that the fixing assembly 45 no longer fixes the position of the positioning plate 442, and then the positioning plate 442 is rotated inside the mounting groove 441 to remove the filter 43, and then a new filter 43 is placed inside the groove 42, and the positioning plate 442 is reset so that the lower end of the positioning plate 442 fits with the filter 43, and the bolt 452 is used to pass through the through groove 451 and is threadedly connected to the inside of the first threaded groove 453, so that the position of the positioning plate 442 can be fixed, so that the first positioning assembly 44 can achieve the function of fixing the position of the filter 43, and then the replacement of the filter 43 is completed, and the operation is simple and easy to use.
