Description

Technical Field

[0001] This utility model relates to the field of generator set technology, specifically to a generator set air intake device. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, control system, noise reduction system, vibration damping system, and exhaust system. Driven by a water turbine, steam turbine, diesel engine, or other power machinery, it converts the energy generated by water flow, airflow, and fuel combustion into mechanical energy, which is then transferred to the generator. The generator then converts this mechanical energy into electrical energy, which is output to electrical equipment. Generators have wide applications in industrial and agricultural production, national defense, science and technology, and daily life. During operation, the air intake of the generator set is crucial for ensuring sufficient air circulation to dissipate heat, smoke, and exhaust gases generated by the engine, generator, and their auxiliary equipment, and to replenish the air needed for combustion.

[0003] The air intake devices used in existing generator sets have the problem of low efficiency in filtering dust and other impurities during use. During the air intake process, dust and other impurities adhere to the filter screen and block the filter screen holes, causing the air intake volume to gradually decrease per unit time, which seriously affects the working efficiency of the generator set. Regularly disassembling and cleaning the filter screen requires stopping the generator's operation, which consumes labor and also reduces the generator's working efficiency. Utility Model Content

The right side of the closing ring 7 is movably locked to the mounting box 3. The filter screen 13 is located between the closing ring 7 and the mounting box 3.

[0026] This utility model provides a generator set air intake device. The specific working principle is as follows: When using this device, the power supply device 23 is turned on to energize the solenoid coil 22. The magnetic field generated by the energized solenoid coil 22 and the solenoid 21 attracts the metal rack 20, causing the rack 20 to slide within the mounting box 3. During the sliding of the rack 20, the first gear 19, meshing with the rack 20, drives the mounting shaft 18 and the pawl 17 to deflect, releasing the restriction on the corresponding ratchet 16, allowing the winding rod 12 to rotate freely. Two sets of motors are started, driving the two winding rods 12 to rotate in the same direction, achieving transmission conversion for the filter screen 13. After the filter screen 13 is converted, the starting motor drives the screw 9 to rotate. Under the limiting action of the fixing frame 6, the closed ring 7 moves and engages with the mounting box 3, fixing the filter screen 13 at the air inlet. The starting motor drives the cam 28 to rotate, intermittently pushing the slider 25. The cleaning brush 24 slides up and down on the fixed rod 26 with the compression spring 27 to clean the surface of the filter screen 13 that is in contact with it, keeping the filter screen 13 clean so that a clean filter screen 13 can be used for air intake filtration in the next transmission. The air inlet of the air intake device is closed by the mounting base 4 and multiple sets of closing plates 29. When the air intake device is not used, the air inlet is closed and the cleaning brush 24 keeps the surface of the filter screen 13 clean, so that the filter screen 13 can still maintain the maximum air intake flow when used next. When using the device, the motor drives the drive wheel 33 to rotate. The mounting ring 5, which is connected to the drive wheel 33 by the external teeth 31, rotates synchronously with the drive wheel 33. The second gear 30, which is connected to the mounting ring 5 by the internal teeth 32, drives the closing plate 29 to rotate. The multiple sets of closing plates 29 rotate synchronously, controlling the opening and closing of the air inlet of the air intake device.
