Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic generator braking, in particular to a hydraulic generator braking device. Background Art

[0002] A hydro-turbine generator is a generator that converts water energy into electrical energy. The working principle of a hydro-turbine generator is that when water flows through a turbine, water energy is converted into mechanical energy. Then the rotating shaft of the turbine drives the rotor of the generator to convert mechanical energy into electrical energy for output. A braking device is required when the hydro-turbine generator stops. For example, a novel hydro-turbine generator brake device with publication number CN216407560U comprises a base, two slots are provided on the upper surface of the base, rod slots are penetrated through the upper ends of the left and right surfaces of the base, the rod slots are connected to the two slots, a long rod is movably sleeved in the rod slot, a cross rod and a threaded block are fixedly connected to the right end of the long rod, a threaded ring is fixedly connected to the right notch of the rod slot, and the threaded ring is threadedly sleeved with the threaded block. The utility model discloses a kind of method for adjusting the height of the cross bar on the slide block, and the method for adjusting the height of the cross bar on the slide block is as follows: when the position of the cross bar is adjusted, the cross bar can be made to rub against different positions of the turntable, thereby avoiding that the cross bar always rubs against the same position on the turntable during mechanical braking, thereby greatly prolonging the service life of the turntable; when adjusting the different positions of the cross bar rubbing against the turntable, it is necessary to manually pull the slide block to slide in the slide groove, drive the insert block to move, make the position of the rod groove and the round groove correspond, and then insert the long rod so that the slide block can no longer move, thereby achieving the effect of adjusting the height of the cross bar on the slide block; this adjustment method is relatively cumbersome, and when braking is completed, it is necessary to pull the limit rod at the same time as the cross bar, so that the limit rod re-jams the limit ring, which is time-consuming and laborious.
