[0023] During the use of a generator, it will get hot and effective heat dissipation of the generator is required. With the emergence of high-efficiency air coolers and the optimization of ventilation structures, large-capacity hydro-generators are all developing towards air cooling. Among them, the design of the air duct has an important impact on the cooling effect, and the wind deflector plays a guiding role in the air duct. During operation and maintenance, the wind deflector is often disassembled and assembled.

[0024] For a hydro-generator unit with a wind deflector made of plastic-steel, its disassembly and assembly work has disadvantages such as small working space, easy damage to the material, and small installation clearance. The existing disassembly and assembly methods usually use tools such as jacks and wooden squares to cooperate for disassembly and assembly, but the tools are not easy to fix and the support stability is poor, resulting in time-consuming and laborious disassembly and assembly process. Therefore, there is an urgent need for an efficient auxiliary device for disassembling and assembling the wind deflector of a generator.

[0025] The following will further elaborate on the technical solution of the present application through specific embodiments in combination with Figures 1 to 3 more details.

[0026] Some embodiments of the present application provide an auxiliary device for disassembling and assembling the wind deflector of a generator, as Figure 1 shown, including: a first support rod 1, a telescopic unit 2, and a second support rod 3 connected in sequence. The telescopic unit 2 is used to drive the second support rod 3 to move back and forth axially; one end of the first support rod 1 away from the telescopic unit 2 is provided with a first mating portion 4, and one end of the second support rod 3 away from the telescopic unit 2 is provided with a second mating portion 5. The first mating portion 4 and the second mating portion 5 are used to cooperate with adjacent legs 6-1 of the wind deflector 6; the first support rod 1 and the second support rod 3 are coaxially arranged, the first mating portion 4 is perpendicular to the first support rod 1, the second mating portion 5 is perpendicular to the second support rod 3, and the first mating portion 4 and the second mating portion 5 are arranged parallel to each other.

[0027] The first support rod 1 and the second support rod 3 are, for example, hollow tubes, the telescopic unit 2 is, for example, a 2.5T reduction drive mechanism, the first mating portion 4 and the second mating portion 5 are, for example, arc-shaped plates, the length of the first support member is, for example, 550mm, the length of the second support member is, for example, 600mm, and the length of the first mating portion 4 and the second mating portion 5 is, for example, 150mm; by providing the first mating portion 4 and the second mating portion 5, it is convenient to cooperate with the legs 6-1 of the wind deflector 6, as Figure 2 shown, so that the device can be positioned between two wind deflectors 6.

[0028] The first mating portion 4 and the second mating portion 5 are parallel to each other and are both perpendicular to the first support rod 1 or the second support rod 3. By driving the second support rod 3 to move through the telescopic unit 2, the device can stably support the adjacent legs 6-1, so as to create a gap between the wind deflectors 6, facilitating disassembly and assembly.

[0029] When in use, support the two matching parts on the adjacent legs 6-1 of the windshield 6 to be removed. As Figure 2 shown, rotate the handwheel 2-6 of the telescopic unit 2 to create a gap of about 5 mm on both sides of the windshield 6, so as to facilitate the removal and reinstallation of the windshield 6. After reinstallation, rotating the handwheel 2-6 will restore the gap. The usage method is simple after use.

[0030] In view of the narrow space in the generator wind tunnel and to prevent items from being left behind, this device can be designed in a detachable and assembled form, with a total of three parts, and small components are all fixed in a welded form, solving the problem of using large tools in the wind tunnel and reducing the number of items entering and leaving the wind tunnel.

[0031] Before using this device, it took 6 workers 2 to 3 hours to remove and reinstall a single windshield 6; after using this device, only 3 workers are needed for removal and reinstallation, which takes 1 hour, greatly improving work efficiency, ensuring the unit's timely resumption of service, and also ensuring safe production.

[0032] This auxiliary device for disassembling and assembling the generator windshield has a simple structure and is easy to use, which can effectively improve the disassembly and assembly efficiency of the windshield 6, saving time and effort.
