[0002] In a thermal power plant, fuel equipment is a core production component, and its stable operation is directly related to the continuous power generation capacity of the power plant. These equipment include coal mills, coal feeders, burners, etc., which are responsible for converting fuel into heat energy, which in turn drives the generator set to generate electricity. Since fuel equipment is in a harsh environment of high temperature, high pressure, high humidity and dust for a long time, its failure rate is relatively high. Once a failure occurs, it may cause power generation interruption, causing huge economic losses and social impact. Therefore, ensuring the normal operation of fuel equipment is crucial for the stable power generation of power plants. This requires not only regular preventive maintenance and overhaul, but also real-time status monitoring and fault warning systems to promptly detect and deal with potential problems, thereby maximizing the reliability and availability of equipment. By adopting advanced overhaul technology and equipment, such as dedicated electric control boxes, more efficient and accurate overhaul can be achieved, downtime can be reduced, equipment life can be extended, and stable operation and continuous power generation of power plants can be ensured. At present, exhaust fans are usually installed in electrical control boxes to ensure the normal operation of internal electronic equipment in high temperature environments. However, exhaust fans are usually fixed in design. The air flow path of fixed exhaust fans is fixed and may not be able to effectively remove the heat in the electrical control box, especially when the equipment heats up unevenly or there are local hot spots, resulting in poor heat dissipation.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] An embodiment of the present invention provides an electric control box for fuel equipment maintenance, which includes: an electric control box 1; exhaust fans 11 are arranged on both sides of the electric control box 1, and the two exhaust fans 11 are distributed up and down; wherein, lifting components capable of moving the exhaust fans 11 up and down are installed on both sides of the electric control box 1, and the lifting components can increase the air circulation inside the electric control box 1 and improve the heat dissipation efficiency; two ventilation holes are opened on the top and bottom of both sides of the electric control box 1, and a ventilation filter plate 12 is installed in each ventilation hole, and a dust cleaning component is arranged on each ventilation filter plate 12; a driving component is installed on the inner top wall of the electric control box 1, and the driving component can drive the lifting component to move.

[0025] It should be noted that: lifting components are installed on both sides of the electric control box 1 to control the up and down movement of the exhaust fan 11. By adjusting the height of the exhaust fan 11, the air circulation path inside the electric control box 1 can be optimized and the heat dissipation efficiency can be improved. The staggered arrangement of fans can form a more complex circulation path for air in the electric control box, increase the contact time and area between the air and the heating element, thereby improving the heat dissipation effect. The two exhaust fans can also be adjusted at the same height to form a stronger airflow, speed up the air circulation speed, and thus improve the heat dissipation effect. Two vents are provided on the top and bottom of both sides of the electric control box 1 to achieve air in and out. A ventilation filter plate 12 is installed in each vent to filter the air entering and discharging the electric control box 1 to prevent dust and other impurities from entering the box. Since the ventilation filter plate 12 will accumulate dust over time, the dust cleaning component is designed to remove the dust to keep the vent unobstructed. The drive component is installed on the inner top wall of the electric control box 1 to control the movement of the lifting component to adjust the height of the exhaust fan 11.

[0026] In an embodiment of the present invention, the lifting assembly includes two reciprocating screws 2 rotatably connected to the inside of the electric control box 1, and the two reciprocating screws 2 are respectively located on both sides of the electric control box 1, and the outer sides of the two reciprocating screws 2 are threadedly connected with reciprocating wire blocks 21, and the relatively close sides of the two reciprocating wire blocks 21 are respectively connected to the exhaust fans 11, and guide rods 22 are arranged on both sides of the two reciprocating screws 2, and the two ends of each guide rod 22 are respectively connected to the inner top and inner bottom walls of the electric control box 1, and the outer side of each guide rod 22 is slidably connected with a guide block 23, and the relatively distant sides of the two exhaust fans 11 are respectively connected to the two guide blocks 23, and the side of the guide block 23 close to the reciprocating screw 2 is connected to the reciprocating wire block 21 through a connecting rod.

[0027] It should be noted that: a reciprocating screw 2 is installed on each side of the inside of the electric control box 1, which is rotatably connected to the inner top wall and the inner bottom wall of the electric control box 1 and can rotate. The outer side of each reciprocating screw 2 is threadedly connected to a reciprocating wire block 21. When the reciprocating screw 2 rotates, the reciprocating wire block 21 moves up and down on the reciprocating screw 2. The relatively close sides of the two reciprocating wire blocks 21 are respectively connected to the exhaust fan 11, so when the reciprocating wire block 21 moves up and down, the exhaust fan 11 also moves up and down accordingly. Guide rods 22 are set on both sides of each reciprocating screw 2, and the two ends of these guide rods 22 are respectively connected to the inner top and inner bottom wall of the electric control box 1, which play a fixing and guiding role. The outer side of each guide rod 22 is slidably connected to a guide block 23, and these guide blocks 23 can slide up and down on the guide rod 22. Two guide blocks 23 are respectively connected to the relatively far sides of the two exhaust fans 11 to ensure that the exhaust fans 11 remain stable during the up and down movement. The side of the guide block 23 close to the reciprocating screw rod 2 is connected to the reciprocating wire block 21 through a connecting rod to achieve synchronous movement of the reciprocating wire block 21 and the guide block 23. The exhaust fan 11 can move up and down inside the electric control box 1 to adjust its height, optimize the air circulation path, and improve the heat dissipation efficiency.

[0028] In an embodiment of the present invention, the driving assembly includes two transmission rods 3 installed on the inner top wall of the electric control box 1, and the two transmission rods 3 are arranged opposite to each other. The relatively far ends of the two transmission rods 3 are connected to a driving bevel gear 31, and one side of the two driving bevel gears 31 is meshed with a driven bevel gear 32. The two driven bevel gears 32 are respectively installed on the outer top of the reciprocating screw 2, and the inner top wall of the electric control box 1 is located between the two transmission rods 3 and a driving member for driving the two transmission rods 3 to rotate is installed.

[0029] It should be noted that two transmission rods 3 are installed on the inner top wall of the electric control box 1. One end of these transmission rods 3 is connected to the inner top wall of the electric control box 1, and the other end is connected to the driving bevel gear 31. The two ends of the two transmission rods 3 that are relatively far away are each connected to a driving bevel gear 31. The driving bevel gear 31 is used to transmit the rotational motion of the transmission rod 3 to the driven bevel gear 32. The driven bevel gear 32 is installed on the outer top of the reciprocating screw 2 and is used to transmit the rotational motion of the driving bevel gear 31 to the reciprocating screw 2. The rotational motion of the driven bevel gear 32 drives the reciprocating screw 2 to rotate, thereby realizing the up and down movement of the reciprocating wire block 21. The driving member is a double-axis motor used to drive the two transmission rods 3 to rotate simultaneously, thereby driving the rotational motion of the driving bevel gear 31 and the driven bevel gear 32. Start of the driving member: After the driving member is started, it drives the two transmission rods 3 to rotate simultaneously. After the driving part is started, it drives the two transmission rods 3 to rotate simultaneously. The rotation of the transmission rod 3 drives the active bevel gear 31 to rotate. The rotation of the active bevel gear 31 drives the driven bevel gear 32 to rotate through the meshing connection. The rotation of the driven bevel gear 32 drives the reciprocating screw 2 to rotate. The rotation of the reciprocating screw 2 causes the reciprocating wire block 21 to move up and down on the reciprocating screw 2. Since the reciprocating wire block 21 is connected to the exhaust fan 11, the exhaust fan 11 also moves up and down accordingly, thereby adjusting its height, optimizing the air circulation path, and improving the heat dissipation efficiency.
