Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of hydro-generator design, and in particular relates to a bulb body cross-support structure of a bulb tubular hydro-generator. Background Art
[0002] The tubular turbine is a new type of unit for developing low-head hydropower resources. It is suitable for heads below 25m. The flow channel of this type of machine is straight and it is a horizontal-axis turbine. The shape of the runner is similar to that of the axial flow type. It also has fixed-propeller and rotating-propeller types. Since the water flow basically moves axially in the flow channel without turning, the water flow capacity and hydraulic efficiency of the unit are greatly improved. The currently known bulb tubular turbine generator is installed in a bulb body, and its bulb body is subjected to static loads such as water thrust, weight, buoyancy, generator torque, generator thermal stress, as well as mechanical vibration caused by the rotation of the rotating parts and hydraulic vibration caused by water pressure changes. This requires that the bulb body must have a good supporting structure type, and the supporting structure must have sufficient rigidity and strength to ensure that the bulb body does not vibrate laterally so that the turbine generator can operate safely and stably.
[0003] The generator base is fixed to the inner cone of the turbine by bolts, and the inner cone is fixed to the foundation ring. This is the main supporting structure of the generator. In order to improve the overall rigidity and strength of the unit, reduce vibration and improve operating stability, auxiliary supports must be added on the upstream side of the unit. Therefore, the use of generator auxiliary support components is of great significance to the safe operation of the generator. The existing bulb body support structure adopts a rigid support. Although the rigid support has a large rigidity, when the rigid support is applied to the bulb flow unit, with the long-term operation of the bulb flow unit, the preload force of the rigid support will gradually disappear, which will bring hidden dangers to the safe operation of the bulb flow unit. Summary of the invention

[0033] In summary:
[0034] When supporting the generator bubble head 2, it is vertically supported by the vertical pillar 9, the basic support rod 11 and the inlet tube 3. When the water flow impacts the generator bubble head 2, one end of the horizontal rod 13 is connected with the movable sphere 14, and is connected to the base frame 1 through the ball head seat 16 and the support block 18. Since the contact point between the horizontal rod 13 and the ball head seat 16 is a spherical surface, it is ensured that the horizontal rod 13 and the generator bubble head 2 bulb flow unit are only subjected to compressive stress during operation, and can adapt to the slight displacement of the generator bubble head 2 under the impact of the water flow, thereby ensuring the safe operation of the bulb flow unit in the generator bubble head 2, and through the mutual cooperation between the oil cylinder barrel 22 and the charging assembly 26, high-pressure oil is injected into the oil cylinder barrel 22 to provide pre-tightening force to the horizontal rod 13, which can play a buffering role, thereby ensuring that the pre-tightening force of the horizontal rod 13 support exists for a long time, and a cross support member is formed by vertical support and horizontal support to ensure the long-term safe operation of the bulb flow unit in the generator bubble head 2.
[0035] The generator bubble head 2 is laterally supported by two support rods 27, and the top rod 29 in the active state is cooperated with so that the fixed block 32 at the bottom of the top rod 29 is stuck in the gear rod 34, which effectively limits the fixed block 32 and forms a right triangle support for the generator bubble head 2. Furthermore, through the mutual cooperation between the first connecting rod 301 and the second connecting rod 304, since the sliding column 302 is slidably connected in the first connecting rod 301, the sliding column 302 can be extended or shortened when adjusting the position of the fixed block 32, so as to form an inverted triangle support for the generator bubble head 2 while adjusting the position of the fixed block 32, thereby further improving the limiting support effect for the generator bubble head 2.
[0036] By the mutual cooperation between the first inclined rod 36 and the second inclined rod 38, the purpose of triangular support of the base frame 1, the inlet tube 3 and the generator bubble head 2 is achieved, thereby further improving the support stability of the generator bubble head 2. By installing an adjustment gasket 10 at the bottom of the vertical support 9 to adjust the support length of the vertical support 9, the distance between the generator bubble head 2 and the base frame 1 is increased, thereby shortening the cantilever length and support angle of the support rod 27, thereby ensuring the working stability of the bulb flow unit in the generator bubble head 2.
