Problems solved by technology
And when the turbine is in use, the temperature of the blade itself will increase with the increase of the working time. When the temperature of the blade is too high, it will cause its own strength to decrease, thereby affecting the use of the device. When the turbine blade is cooled, it cannot absorb heat and blow out cold air at the same time, so that the cooling speed of the turbine blade is relatively slow, and the cooling effect of the turbine blade is not good, and the existing turbine blade cooling device can only blow cold air from a fixed angle, so that The cooling of the turbine blades is not uniform, which further affects the cooling effect of the turbine blades, increases the cooling time of the turbine blades, and further affects the practicability of the device

The invention discloses a turbine blade cooling device which comprises a sealing door, a heat preservation box, an air guide pipe, an installing plate, a first induced draft fan, an evaporator, an elastic air outlet pipe, a second induced draft fan, a threaded hole, a water pump, a first flow guide pipe, a winding roller, a rotating shaft, a motor, a rope, an air outlet head, an air outlet pipe, an air sucking pipe and a second flow guide pipe. Cold air is blown in while the device absorbs heat, and therefore the radiating speed and the cooling effect of a turbine blade are improved; when themotor works, the air outlet head swings, the cold air can be blown to the blade at multiple angles and in multiple directions, the cooling effect of the turbine blade is further improved, the servicelife of the turbine blade is guaranteed, meanwhile, time needed by cooling the turbine blade is shortened, the halt maintaining time of a machine is shortened, and the device practicability is furtherimproved; and the device can remind a worker to add an ice water mixture in time, the device can be more scientific and intelligent, and the device practicability is improved.
Description
technical field [0001] The invention relates to a cooling device, in particular to a turbine blade cooling device. Background technique [0002] A gas turbine is an internal combustion power machine that uses a continuous flow of gas as a working medium to drive the impeller to rotate at a high speed and convert the energy of the fuel into useful work. It is a rotary impeller heat engine. And when the turbine is in use, the temperature of the blade itself will increase with the increase of the working time. When the temperature of the blade is too high, its own strength will be reduced, which will affect the use of the device. The existing turbine blade cooling device is not suitable for When the turbine blade is cooled, it cannot absorb heat and blow cold air at the same time, so the cooling speed of the turbine blade is slow, and the cooling effect of the turbine blade is not good, and the existing turbine blade cooling device can only blow cold air from a fixed angle, s...
