Description

Vertical hydroelectric set back wheel separation appurtenance

Technical Field

A backrest wheel separation auxiliary tool of a vertical hydroelectric generating set belongs to the technical field of hydroelectric generating set structures.

Background

The hydraulic generator is a generator which takes a hydraulic turbine as a prime motor to convert water energy into electric energy, when water flow passes through the hydraulic turbine, the water energy is converted into mechanical energy, a rotating shaft of the hydraulic turbine drives a rotor of the generator, and the mechanical energy is converted into electric energy to be output, so that the hydraulic generator is main power equipment for producing electric energy of a hydropower station; the main shaft of the water turbine adopts a double-flange structure, the upper flange is connected with the main shaft of the generator, and the lower flange is connected with the rotating wheel. However, in the overhauling process of the hydraulic generator, water often enters the flange surface through the hollow main shaft, and rust phenomenon occurs, so that the generator shaft and the hydraulic generator shaft cannot be actively separated. If the backrest wheels cannot be separated in time, the follow-up rotor hanging progress can be influenced, so that the overhaul period is prolonged, and the overhaul cost and the loss of manpower and material resources are greatly increased.

Detailed Description

The utility model will now be described in detail with reference to the drawings and to specific embodiments.

The utility model provides a vertical hydroelectric set back wheel separation appurtenance, includes baffle 1, nut 2 and with nut 2 matched with screw rod 3, screw rod 3 one end stretches out nut 2 back to baffle 1 direction extension, just baffle 1 is connected with last flange 8, screw rod 3 is connected with lower flange 9.

Wherein, the screw rod 3 is kept away from the integrative rotor plate 31 that is fixed with of one end of baffle 1, keep away from central point put fixedly connected with handle 4 on the rotor plate 31.

The end face of the baffle plate 1 is fixedly provided with a gasket 5 which is coaxially arranged with the screw rod 3, and the size of the gasket 5 is the same as the diameter of the screw rod 3.

The nut 2 is provided with a coaxial opening clamp spring 6, and the opening clamp spring 6 is attached to one side of the nut 2, which is close to the baffle 1, and is clamped with the screw 3.

The opening clamp spring 6 is provided with a plurality of clamping teeth 61, and the clamping teeth 61 are matched with threads of the screw 3.

The working principle of the utility model is as follows:

the device is arranged in four directions of an upper flange 8 and a lower flange 9, a baffle plate 1 of the device is welded on the side surface of the upper flange 8 of the backrest wheel, and a nut 2 is welded on the side surface of the lower flange 9; the screw 3 is screwed by using the rotary handle 4, so that the tail end of the screw 3 is propped against the baffle plate 1 at the other end, a separating force is generated between the flanges, and the flanges are separated by adding the dead weight of the turbine shaft 10; by arranging the gasket 5 on the baffle plate 1, the abrasion of the end of the screw 3 to the baffle plate 1 can be reduced; the opening clamp spring 6 coaxially arranged with the nut 2 can not displace any more when the handle 4 is not rotated because the screw thread of the screw 3 is clamped by the clamp tooth 61 when the screw 3 is screwed to a length which meets the requirement of separating the upper flange 8 and the lower flange 9, so that the non-return function is achieved.
