Embodiment Construction
[0014] The present invention will be described in detail below with reference to the accompanying drawings.
[0015] Component names in the picture: outer steel plate 1, energy-absorbing material layer 2, inner steel plate 3, servo motor 4, lead screw 5, sliding base 6, guide rod 7, strip hole 8, bearing mounting plate 9, nut 10 , key 11, groove 12.
[0016] like figure 1 , figure 2 As shown, the hydraulic bulging protective sleeve of the generator retaining ring adopts a three-layer cylindrical structure as a whole. In this specific embodiment, the inner layer is the outer steel plate 3 with a thickness of 20mm, the outer layer is the outer steel plate 1 with a thickness of 20mm, and the middle layer is the outer steel plate 1 with a thickness of 40mm. 50mm layer of energy-absorbing material 2 . When a burst accident occurs, the high-pressure liquid acts on the inner steel plate 3 of the protective sleeve, and the energy is greatly reduced through the energy absorption of...

Abstract
The invention discloses a hydraulic bulging protective casing for a shroud ring of a generator, and relates to the protective casing for the generator. The protective casing comprises steel plates, an energy absorption material layer, a servo motor, a screw rod, a sliding base, a guide rod and a groove. The overall hydraulic bulging protective casing for the shroud ring of the generator adopts a three-layer cylindrical structure, and in the three-layer cylindrical structure, an inner layer is an inner-layer steel plate (3), an outer layer is an outer-layer steel plate (1) and a middle layer is the energy absorption material layer (2). A sensor is arranged on the sliding base (6) capable of sliding up and down. The sliding base (6) and the outer-layer steel plate (1) of the protective casing are circumferentially fixed. A sensor mounting base is embedded into the groove (12) on the two sides of a slotted hole of the outer-layer steel plate of the protective casing. The screw rod (5) isdirectly connected with the motor (4) by a key (11). A nut (10) is welded on the sliding base. The other side of the sliding base is provided with the guide rod (7) symmetrical to the screw rod. The motor and a support bearing mounting plate (9) of the screw rod are welded on the steel plates of the protective casing. The security and universality of the protective casing are improved, and the needs of dynamic measurement of deformation parameters are satisfied.
Description
technical field [0001] The invention relates to a protective cover for a generator, in particular to a hydraulically bulging energy-absorbing protective cover for a generator retaining ring capable of installing a dynamic measuring element. It is used in the hydraulic bulging production process of the generator retaining ring, when the generator retaining ring bursts accidentally, it protects personnel and equipment from the damage caused by the high-pressure liquid and the measuring device flying out forcefully, and facilitates the dynamic measurement of deformation parameters. Background technique [0002] Generator guard ring is one of the most critical components in the generator set. It is a ring used to tighten the winding coils at both ends of the generator rotor. Although the shape is simple, it bears assembly stress, centrifugal force, bending stress and thermal stress during operation. , is the main part that bears the greatest stress in the generator set. At pres...
