Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.
Example one
Referring to fig. 1, the embodiment discloses a full bunker early warning device of coal bunker, including coal bunker 1, belt feeder 2, early warning device 3 and dust cover 4, belt feeder 2 is fixed in the left side of coal bunker 1 upper end, still is fixed with above the coal bunker and is used for dirt-proof dust cover 4, early warning device 3 is fixed on dust cover 4.
The rotating rod 34 is horizontally arranged, the toggle switch 31 is rotatably connected with the center of the rotating rod 34, and the operation of the toggle switch 31 is controlled by rotating the rotating rod 34; rope 35 is wire rope, rope 35 one end with the one end that belt feeder 2 was kept away from to dwang 34 is connected, and the other end is followed one side cang arm that belt feeder 3 was kept away from in bunker 1 and is transferred perpendicularly to 2-3m down at the top of bunker 1 for bunker 1 has the high early warning buffer zone of 2-3m when full storehouse, can guarantee that the pile coal on belt feeder 2 carries and can not appear the heavy load and press the car accident in bunker 1, and belt feeder 2 is kept away from to rope 35, causes the error of pulling down to rope 35 when reducing the coal whereabouts on belt feeder 2, and then reduces monitoring error.
Carry coal in to coal bunker 1 through belt feeder 2, refer to fig. 2, can bury rope 35 when coal reachs the tip of rope 35, thereby slowly drive rope 35 drop-down, drive dwang 34 and rotate, thereby make toggle switch 31 convert closed state into by normally opening, and then make alarm 32 report to the police, belt feeder driver or patrol personnel in time contact higher level shipment system after discovering and reduce the shipment or increase the speed of putting goods of 1 end of coal bunker, prevent that the heavy load from stopping in full storehouse, reduce economic loss, the setting of sensor has been replaced simultaneously, not only reduce the error of coal bunker monitoring, and rope 35 is difficult for receiving the influence of dust and fog, thereby can not change rope 35 frequently, and then the cost is reduced.
Furthermore, the one end of the rotating rod 34 far away from the rope 35 is further connected with a first limiting rope 36, the other end of the first limiting rope 36 is fixed on the inner wall of the dust cover 4 in the direction of lowering the rope 35, the first limiting rope 36 is in a relaxed state, and when the rope 35 is pulled down to drive the rotating rod 34 to rotate, the rotating rod 34 at the end of the first limiting rope 36 rotates upwards, so that the first limiting rope 36 is stretched and pulled on the rotating rod 34, and the rotating rod 34 is prevented from being rotated too much due to the too large pulling force of the rope 35, and the work of the toggle switch 31 is influenced.
The utility model discloses a theory of operation is: referring to fig. 1, when the coal filling amount in the coal bunker 1 does not exceed the end of the rope 35, the toggle switch 31 is in a normally closed state, the alarm 32 does not give an alarm, and the belt conveyor 2 continues to convey coal into the coal bunker 1. Referring to fig. 2, when coal reaches the end of the rope 35 and continues to convey coal, the coal buries the rope 35, so that the rope 35 is slowly pulled down to drive the rotating rod 34 to rotate under the action of friction force, meanwhile, the rotating rod 34 is prevented from rotating too much due to the pulling down force of the rope 35 by the arrangement of the first limiting rope 36, the work of the toggle switch 31 is influenced, finally, the toggle switch 31 is switched from a normally open state to a closed state, and the alarm 32 gives an alarm, a belt conveyor driver or a patrol person timely contacts a superior delivery system to stop delivery or reduce the coal feeding amount to the belt conveyor 2 after finding out, heavy load full-bin parking is prevented, economic loss is reduced, the arrangement of a sensor is replaced, errors of coal bin monitoring are reduced, the rope 35 is not easily influenced by dust and fog, and the rope 35 cannot be frequently replaced, thereby reducing the cost.
Example two
Referring to fig. 3, this embodiment is different from embodiment one, dwang 34 is vertical to be set up, toggle switch 31 with the top of dwang 34 is rotated and is connected, still fixed support rod 37 between two inner walls that dust cover 4 is relative, the upper surface of bracing piece 37 with the bottom of dwang 34 flushes, rope 35 one end is connected with toggle switch 31's bottom, and the other end is hung and is established at bracing piece 37 and along the perpendicular top of transferring to coal bunker 1 down 2-3m of transferring to one side cannel arm that belt feeder 3 was kept away from to coal bunker 1.
The supporting rod 37 can be rotationally fixed between the inner walls of the dust cover 4, so that the friction force of the rope 35 on the supporting rod 37 is reduced, the monitoring precision of the pre-tightening device is further improved, and the error is reduced.
The bottom end of the toggle switch 31 is further connected with one end of a second limiting rope 38, the other end of the second limiting rope 38 is fixed on the inner wall of the dust cover 4 towards the side far away from the support rod 37, and the second limiting rope 36 is also in a relaxed state when the bin is full; referring to fig. 4, when the rope 35 is buried by coal, the rope 35 is pulled down to drive the rotating rod 34 to rotate, and the rotating rod 34 is also prevented from rotating too much due to too much force of the rope 35 pulling down on the rotating rod 34, which affects the operation of the toggle switch 31.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
