AI Technical Summary
The traditional generator cooling method takes away heat by speeding up the air flow rate, but it cannot significantly reduce the temperature of the air and generator housing, resulting in a lack of significant cooling effect.
A generator cooling device for hydropower stations is designed, including cooling cylinders, cooling pipes, fans, water pumps and activated carbon plates. Air is sucked in through the fan and cooled through the cooling pipe, and then transported to the inside of the housing through the connecting pipe, significantly reducing the air temperature. At the same time, the activated carbon plate filters water vapor and dust in the air to protect the generator.
Through the design of cooling tubes and rectangular tubes, the device significantly reduces the temperature of the generator housing and improves the cooling effect. The use of activated carbon board further protects the generator, avoids the entry of dust and water vapor, and facilitates replacement and cleaning.

Description
Technical Field
[0001] The utility model relates to the technical field of generator cooling devices, and more specifically, the utility model relates to a generator cooling device for a hydropower station. Background Art
[0002] A hydraulic generator is a power generation unit formed by combining each water turbine and a supporting generator on a hydropower station, and is the main power equipment for generating electric energy in a hydropower station.
[0003] The function of a hydraulic generator set is to flow the water with potential energy at a high place such as a river or a lake to a low place, convert it into the mechanical energy of the water turbine through the water turbine, and the water turbine then drives the generator to generate electricity, converting the mechanical energy into electrical energy. A large amount of heat will be generated during the operation of the generator. In order to ensure the normal operation of the hydraulic generator, it is necessary to dissipate the heat of the generator. The traditional heat dissipation method is to accelerate the air flow speed near the generator, thereby taking away the heat generated by the generator, so as to cool the generator. However, this method does not cool the temperature of the air and the generator housing, so that the temperature of the air is close to room temperature, and thus the cooling effect is not significant. Therefore, it needs to be improved. Summary of the Utility Model

[0038] Among them, the right side of the cooling cylinder 9 is fixedly connected with a fixed box 18, and the bottom of the fixed box 18 is fixedly connected with the top of the mounting frame 5.
[0039] By setting the fixed box 18, the outside air can enter the inside of the cooling cylinder 9 through the fixed box 18.
[0040] Among them, limit blocks 19 are fixedly installed on both the top and bottom of the inner surface of the fixed box 18, and an activated carbon plate 20 located between the limit blocks 19 is movably sleeved inside the fixed box 18.

[0045] By setting the clamping block 26, the clamping block 26 can play a role in fixing the fixed block 23, so as to fix the activated carbon plate 20.
[0046] Among them, the right end of the clamping block 26 is fixedly connected with a spring 25, the other end of the spring 25 is fixedly connected with the inner surface of the installation box 24, the outer surface of the clamping block 26 is fixedly connected with a pull plate 27, and the outer surface of the pull plate 27 is movably connected with the inner surface of the installation box 24.
[0047] The operator can drive the clamping block 26 to move by pulling the pull plate 27, so that the clamping block 26 disengages from the inside of the fixed block 23.
[0048] The working principle and usage process of the utility model:
[0049] When it is necessary to cool the generator body 3, the operator starts the fan 6 and the water pump 15, so that the coolant can be sucked into the water inlet pipe 17, and then is transported to the inside of the cooling pipe 10 through the water outlet pipe 16, so that the cooling pipe 10 can cool the air inside the cooling cylinder 9. When the coolant inside the cooling pipe 10 enters the inside of the rectangular pipe 13 through the infusion pipe 12, it will cool the housing 2. Since the cross section of the rectangular pipe 13 is rectangular, the contact area between the rectangular pipe 13 and the housing 2 is increased, thereby improving the cooling effect on the housing 2, and further reducing the temperature of the air inside the housing 2. The start of the fan 6 will cause the air inlet pipe 7 to generate suction, so that the fixed box 18 can suck the outside air into the inside of the cooling cylinder 9, and then is transported to the inside of the housing 2 through the air outlet pipe 8 and the connecting pipe 11, so as to cool the air inside the housing 2, and thus the generator body 3 can be cooled, making the cooling effect more remarkable.
[0050] By setting the activated carbon plate 20, the activated carbon plate 20 can filter the water vapor and dust in the air, preventing air and dust from entering the inside of the housing 2. When the operator needs to replace the activated carbon plate 20, the operator can pull the pull plate 27 to drive the clamping block 26 to disengage from the inside of the fixed block 23, thereby releasing the fixing effect on the fixed block 23 and the activated carbon plate 20. At this time, the operator can pull the handle 22 outwards to drive the activated carbon plate 20 to disengage from the inside of the fixed box 18, which facilitates the operator to replace and clean the activated carbon plate 20.
