Description

Technical Field

[0001] This utility model relates to the field of generators, and in particular to a generator air-cooling device. Background Technology

[0002] The air cooler is a surface heat exchanger installed at the bottom of the generator. It uses circulating water to enter copper pipes as a cooling medium to cool the heated air discharged from the generator. The cooled air then returns to the generator cooling system from both sides to cool the generator, and the cycle repeats continuously.

[0003] In daily production operations, the generator air cooler is a fixed type (i.e., permanently installed at the bottom of the generator). Because of its low, narrow, and inflexible location, it is difficult to access for maintenance or requires shutdown, resulting in prolonged maintenance time and reduced power generation efficiency. Furthermore, the air cooler uses circulating water, which, due to its poor quality, easily causes scale buildup inside the copper pipes, making thorough cleaning and inspection difficult and affecting cooling performance. This presents numerous inconveniences in maintenance, inspection, and cleaning. Moreover, when the generator is not running for extended periods, the water in its pipes can easily condense on the outside air, resulting in high humidity and affecting generator insulation testing.

[0004] Therefore, there is an urgent need for an air-cooled generator device to solve the above problems. Utility Model Content

[0005] This utility model aims to at least partially solve one of the problems existing in the prior art. To this end, this utility model proposes a generator air-cooling device. By setting a drive structure, the air cooler is automatically pushed out of the housing cavity and onto the support frame when maintenance or replacement is required, so that the user can perform corresponding operations on the air cooler. The structure is simple and easy to implement, which can improve the maintenance efficiency of the air cooler without affecting its normal use. It can also pull the air cooler out from the bottom of the generator when the air cooler is not used for a long time, avoiding water in the air cooler pipes from causing condensation in the external air, thus preventing excessive air humidity and affecting the generator insulation monitoring.

[0037] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0038] Please refer to Figure 1 and Figure 2 This utility model provides a generator air-cooling device, including a mounting box 101, a drive structure 2, a support frame 4, and an air cooler 1. The mounting box 101 has a receiving cavity 100. The drive structure 2 is installed at the bottom of the receiving cavity 100. The support frame 4 is located on one side of the mounting box 101. The air cooler 1 is located within the receiving cavity 100 and is connected to the output end of the drive structure 2. The drive structure 2 can drive the air cooler 1 to move between a first position and a second position. When the air cooler 1 is in the first position, it is located within the receiving cavity 100; when the air cooler 1 is in the second position, it is located outside the mounting box 101 and rests on the support frame 4. By setting up a drive structure 2, the air cooler 1 can be automatically pushed out of the receiving cavity 100 and onto the support frame 4 when maintenance or replacement is required. This facilitates the user's operation of the air cooler 1. The structure is simple and easy to implement, which can improve the maintenance efficiency of the air cooler 1 without affecting its normal use. It can also pull the air cooler 11 out from the bottom of the generator when the air cooler 11 is not used for a long time, thus preventing water in the air cooler 11 pipes from causing condensation in the external air, which would result in excessive air humidity and affect the generator insulation monitoring.

[0039] Optionally, the height of the support frame 4 is the same as the height of the bottom side of the air cooler 1, so that the drive structure 2 can stably push the air cooler 1 from the accommodating cavity 100 onto the support frame 4, or push it from the support frame 4 into the accommodating cavity 100.

[0040] Optionally, the support frame 4 is slidably connected to the housing 101, allowing the support frame 4 to slide relative to the housing 101 between a third and a fourth position. When the support frame 4 is in the third position, it is located inside the receiving cavity 100; when it is in the fourth position, it is located outside the housing 101. When the air cooler 1 needs repair or replacement, the support frame 4 is pulled out from the receiving cavity 100 to the outside of the housing 101 to support the air cooler 1. After the air cooler 1 has been repaired or replaced, the support frame 4 is pushed back into the receiving cavity 100 from the outside of the housing 101 for easy storage.

[0041] Optionally, it also includes a buckle 5, which is disposed between the support frame 4 and the mounting box 101. When the support frame 4 is in the fourth position, the support frame 4 and the mounting box 101 are fixedly connected by the buckle 5, thereby ensuring the relative position between the support frame 4 and the mounting box and preventing the support frame 4 from moving relative to the mounting box when the air cooler 1 is pulled out from the housing cavity 100.

[0042] Optionally, a roller 41 is provided at the bottom of the support frame 4, the left end of the support frame 4 is slidably connected to the bottom of the placement box 101, and the roller 41 is provided at the right end of the support frame 4 so as to facilitate the sliding of the support frame 4 relative to the placement box 101.

[0043] Specifically, the support frame 4 can be pulled out from the accommodating cavity 100 to the left side of the placement box 101.

[0044] Optionally, the upper side of the support frame 4 is provided with a slide rail 3 corresponding to the air cooler 1, and the air cooler 1 can slide along the slide rail 3, thereby improving the sliding stability of the air cooler 1 on the support frame 4.

[0045] Optionally, a limit switch 6 is also included. The limit switch 6 is installed inside the housing 101 and is communicatively connected to the drive structure 2. When the air cooler 1 is pushed into the housing 100 by the drive structure 2, the limit switch 6 is triggered and sends a signal to the drive structure 2, causing the drive structure 2 to stop moving, so as to prevent the air cooler 1 from excessively impacting the inner wall of the housing 101.

[0046] Optionally, the drive structure 2 includes a drive motor 23, a gear 21, a rotating shaft 24, and a chain 22. Gears 21 are mounted on both the left and right ends of the bottom of the gear housing 101, and are installed at the output end of the drive motor 23. The gears 21 are mounted on the bottom of the housing 101 via the rotating shaft 24. The left end of the chain 22 is meshed with the gear 21 located at the left end of the housing 101, and the right end of the chain 22 is meshed with the gear 21 located at the right end of the housing 101. When the air cooler 1 is in the first position, it rests on the upper side of the chain 22. When the motor rotates, it drives the gear 21 to rotate, which in turn drives the chain 22 to rotate, thereby causing the air cooler 1 resting on the upper side of the chain 22 to move between the first and second positions.

[0047] Optionally, a first baffle 102 is also included. A first through hole 200 communicating between the receiving cavity 100 and the outside of the housing 101 is provided on the lower left side of the housing 101. The first baffle 102 is installed on the left side of the housing 101 and is used to close and open the first through hole 200. The air cooler 1 moves between a first position and a second position through the first through hole 200. When the air cooler 1 is moved out of the receiving cavity 100, the first baffle 102 closes the first through hole 200 to ensure the airtightness of the housing 101.

[0048] Optionally, a second baffle 103 is also included. A second through hole 300 communicating between the receiving cavity 100 and the outside of the receiving box 101 is provided on the lower right side of the receiving box 101. The second baffle 103 is installed on the right side of the receiving box 101 and is used to close and open the second through hole 300. The water pipe of the air cooler 1 is connected to the external water pipe through the second opening. When the air cooler 1 is removed from the receiving cavity 100, the second baffle 103 closes the second through hole 300 to ensure the airtightness of the receiving box 101.

[0049] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
