Technical Field

[0001] This utility model relates to the field of boiler soot blowing, and in particular to a boiler soot blowing device for power plants. Background Technology

[0002] A power plant boiler refers to a medium-to-large-sized boiler in a power plant that provides a specified quantity and quality of steam to a steam turbine. It is one of the main thermal equipment in a thermal power plant, often paired with a steam turbine generator set of a certain capacity, primarily used for power generation. There are two main types of power plant boilers: pulverized coal boilers and circulating fluidized bed boilers. These two types are currently the main types used in power plants. With the development of science and technology, boiler soot blowing devices are becoming increasingly common and their functions are becoming more powerful. Power plants also frequently use boiler soot blowing devices.

[0003] Existing soot blowing devices for cleaning boilers in power plants lack height adjustment capabilities, making them unsuitable for soot blowing on boilers of different heights. This results in limited practicality and inconvenience in their use. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a first motor drives a worm gear to rotate, which in turn drives a pair of worm wheels to rotate in the opposite direction. The pair of worm wheels then drive two pairs of round rods to rotate, which in turn drive a connecting rod to rotate. The connecting rod then drives a sliding rod to move up and down, and the two pairs of sliding rods drive the worktable to move up and down. This allows the device to adjust its height, enabling it to blow soot according to boilers of different heights. This makes the soot blowing device highly practical and easy to use.
