Example IV
The force unloading device 300 in the above embodiment is that the adjusting body 330 can be pulled to rotate by the inner pull rope 350 when being broken by the fragments of the flywheel 140 for the first time, so that the rotation of the drum 310 is delayed to a higher degree; the embodiment of the present application optimizes the lower housing 120 to some extent on the basis of the above-described embodiment.
As shown in fig. 13 and 14, the lower housing 120 includes an inner cylinder 121 and a spiral pipe 122; the inner cylinder 121 is a main body part of the lower shell 120, and the spiral tube 122 is spirally fixed on the outer side wall of the inner cylinder 121; the spiral pipe 122 is filled with medium, and the medium in the spiral pipe 122 is the same as the medium in the regulating body 330; the end of the inner pull cord 350 remote from the drum 310 is secured to the coil 122.
Further, as shown in fig. 15 and 16, the spiral tube 122 is made of rubber, and in the initial state, the spiral tube 122 is in an expanded state under the action of an internal medium; after the fragments of the flywheel 140 pass through the spiral tube 122, the spiral tube 122 is broken, and the medium in the spiral tube 122 flows out, so that the spiral tube 122 is retracted, and the diameter of the spiral tube 122 is reduced; the inclined plate 320 abutting against the spiral tube 122 moves relatively to the spiral tube 122 after the diameter of the spiral tube 122 is reduced, so that the inner tension cord 350 pulls the drum 310 to rotate.
The working principle of the force unloading device 300 in the generator energy storage device for the micro-grid in use is as follows:
the flywheel 140 energy storage system rotates at a high speed during the use process, if the flywheel 140 is decomposed under the unexpected circumstance, the decomposed fragments pass through the lower shell 120 to move towards the direction of the force unloading device 300, and at the moment, the inner tension rope 350 pulls the rotary drum 310 to rotate; the decomposed fragments collide with the rotating drum 310, the fragments are subjected to tangential force generated when the drum 310 rotates, the tangential force is in the tangential direction of the contact point of the fragments and the drum 310 and points to the rotating direction of the drum 310, the trend of the force is changed when the fragments move under the action of the tangential force, and part of kinetic energy of the fragments is converted into rotational kinetic energy to be spread and consumed in order to overcome the tangential force of the drum 310; if the fragments enter the wall of the rotary drum 310, the rotary drum 310 drives the fragments to rotate, the action time of tangential force of the rotary drum 310 is prolonged in the process, and the force is removed from the fragments in the process that the rotary drum 310 drives the fragments to rotate; specifically, if the flywheel 140 is decomposed when rotating in the counterclockwise direction, and the medium tube 340 is pushed in the initial state, so that the drum 310 rotates clockwise to wind the internal tension rope 350 on the outer sidewall of the lower housing 120, when the broken piece after the flywheel 140 is decomposed is unloaded, the internal tension rope 350 pulls the drum 310 to rotate in the counterclockwise direction (i.e. the rotation direction of the drum 310 is the same as the rotation direction of the flywheel 140), a tangential force is applied to the broken piece by the drum 310 at a certain rotation speed, and part of kinetic energy of the broken piece is converted into rotational kinetic energy under the action of the tangential force to be amortized and consumed, and the broken piece decomposed by the flywheel 140 drives the drum 310 to continue to rotate when the broken piece collides with the drum 310 at the moment, so that the overall unloading effect of the unloading device 300 is obvious; if the flywheel 140 is disassembled when rotating in the counterclockwise direction, and the medium tube 340 is pushed in the initial state, the drum 310 rotates counterclockwise to wind the internal tension rope 350 around the outer sidewall of the lower housing 120, when the broken pieces after the flywheel 140 are disassembled, the internal tension rope 350 pulls the drum 310 to rotate in the clockwise direction (i.e., the rotation direction of the drum 310 is opposite to the rotation direction of the flywheel 140), a tangential force is applied to the broken pieces by the drum 310 at a certain rotation speed, and part of the kinetic energy of the broken pieces is converted into rotational kinetic energy under the action of the tangential force to be split and consumed, and the broken pieces decomposed by the flywheel 140 are blocked from continuing to rotate by the drum 310 when the broken pieces collide with the drum 310 at the moment, so that the overall force unloading effect of the force unloading device 300 is poor.
The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:
by providing the spiral tube 122, the inner pull cord 350 pulls the drum 310 to rotate when the spiral tube 122 is first broken by the fragments of the flywheel 140, reducing the degree of delay in rotation of the drum 310 after the fragments of the flywheel 140 pass through the lower housing 120; the spiral tube 122 is filled with medium, and can absorb heat and cool the inner tube 121 to a certain extent.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art.
