Description

Technical Field

[0001] The utility model relates to the technical field of water turbine generator fixing devices, in particular to a water turbine generator fixing device. Background Art

[0002] A hydroelectric generator is an AC synchronous generator driven by a water turbine that converts the mechanical energy of water flow into electrical energy. There are many types of hydroelectric generators, including impulse turbines, axial flow turbines, tubular turbines, and mixed flow turbines. The impulse turbine is a turbine that uses the kinetic energy of high-pressure jet water to do work. Water from a high-head reservoir is led to the turbine through a pressure pipe. The high-pressure water passes through the turbine nozzle and becomes a high-speed jet of water, rushing towards the bucket of the turbine, causing the turbine to rotate and do work. There are three main types of impulse turbines: cut-off turbines, oblique-impact turbines, and double-impact turbines.

[0003] However, it still has the following disadvantages in actual use:

[0004] The existing fixing devices for hydro-turbine generators cannot adapt to hydro-turbine generators of different specifications, which means that if the hydro-turbine generator needs to be replaced or upgraded, a new fixing device needs to be redesigned and installed, which increases time and cost.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a fixing device for a hydro-generator, comprising:

[0008] A main body component, the main body component comprising a first fixing block, a second fixing block, a first clamping plate, a second clamping plate, a first limiting column, and a second limiting column;

[0018] 1. The utility model, through the main assembly provided, when fixing the hydro-turbine generator, the staff places the hydro-turbine generator between the first clamping plate and the second clamping plate through a crane.
