Description

Technical Field

[0001] The utility model relates to the technical field of diesel generators, in particular to a cooling device for a diesel generator set. Background Technique

[0002] A diesel generator is a small power generation device, which refers to a power machine that uses diesel and other fuels and uses a diesel engine as a prime mover to drive a generator to generate electricity; the main uses of diesel generators are: 1. Power supply for daily use: Although the power of diesel generator sets is relatively low, due to their small size, flexibility, portability, complete supporting facilities, and ease of operation and maintenance, they are widely used in mines, railways, field construction sites, road traffic maintenance, as well as factories, enterprises, hospitals and other departments; 2. As an emergency power supply: Diesel generator sets are used in places not connected to the power grid, or as emergency power supplies in the event of a power grid failure, and for more complex applications such as peak tripping, power grid support and grid output.

[0003] During the use of a diesel generator, heat is generated, and generally a cooling fan is used to dissipate heat from it. However, the fan of the cooling fan can only blow air to cool a certain position of the diesel generator components, and cannot cool the diesel generator evenly. Therefore, it is impossible to fully cool the diesel generator, which easily causes faults in the diesel generator and makes it inoperable.

[0004] Therefore, we propose a cooling device for a diesel generator set to solve the problems mentioned above. Content of the Utility Model

A reciprocating lead screw 83 is fixedly installed at the shaft end of the power output shaft of the cleaning motor 82. One end of the reciprocating lead screw 83 movably penetrates the inner cavity of the adjacent support plate 81 and is rotatably connected to the side away from the support plate 81.

[0032] Working principle: When the present utility model is in use, heat is generated during the operation of the diesel generator set main body 5. The fan 6 is started to dissipate heat and cool the diesel generator set main body 5. When the fan 6 is started, the drive motor 76 can be started at this time. The rotation of the power output shaft of the drive motor 76 drives the cam 77 fixed at the shaft end of the power output shaft of the drive motor 76 to rotate. Thus, the T-shaped rack plate 75 can reciprocate left and right under the combined action of the telescopic rod 751, the spring 752, and the fixed block 753 through the cam 77. The rotation of the adjacent movable shaft 71 can be realized through the rotating gear 74 meshing with the T-shaped rack plate 75. The reciprocating swinging of several swing plates 72 can be achieved through the adjacent hinge rods 73 hinged on the swing plates 72, thereby changing the cooling air direction of the fan 6. When dust accumulates at the bottom of the filter screen A2, the cleaning motor 82 can be started at this time. The rotation of the power output shaft of the cleaning motor 82 drives the reciprocating lead screw 83 fixed at the shaft end of the power output shaft of the cleaning motor 82 to rotate. Thus, the lead screw nut 84 moving on the outer periphery of the reciprocating lead screw 83 can move back and forth at the bottom of the filter screen A2. The dust on the bottom of the filter screen A2 can be cleaned through the cleaning brush 86, avoiding the blockage of the filter screen A2 and affecting the ventilation rate of the filter screen A2. And by setting the trapezoidal block 861, the magnet A862, and the magnet B863, it is convenient to replace the damaged cleaning brush 86.
