The intelligent walking system and the intelligent fire scanning system can be realized without doubt by the existing automation technology, so the invention is specifically described for an execution structure of fire extinguishing.

The specific working process is as follows: in the initial state of the device, when the fire is not extinguished, the displacement mechanism 2 enables the platform 3 to be at the lowest position. The sand silo 4 is filled with sand, as shown in fig. 8 and 9, one end of the upper toothed plate 22 with the end block 42 is attached to one end of the gate plate 28 with the L-shaped block 41, the end block 42 is spaced from the corner end of the corresponding L-shaped block 41, and the upper toothed plate 22 blocks the sand outlet 27 of the sand silo 4; as shown in FIG. 8, the sandbox 29 is located at the inclined lower end of the sliding path, the sandbox 29 is just corresponding to the sand outlet 27, the swing plate 46 is attached to the stop 48, the swing plate 46 is perpendicular to the bottom surface of the sandbox 29, the rear end surface of the sandbox 29 is attached to the A cushion 31, the side surface of the slide block 35 is attached to the side surface of the push plate 32, and the pull rope 36 is in a tensioned state.

When a fire disaster occurs indoors, the device can quickly reach a fire disaster area and stop short of the fire disaster. And starting the B electric driver 15, as shown in fig. 8, the B electric driver 15 drives the B gear 20 to rotate clockwise, the B gear 20 rotating clockwise drives the upper toothed plate 22 to move in a direction away from the gate plate 28, the end block 42 moving synchronously with the upper toothed plate 22 is attached to the corner end of the corresponding L-shaped block 41 after moving for a short distance, then the upper toothed plate 22 pulls the L-shaped block 41 through the end block 42 to enable the gate plate 28 to move synchronously with the upper toothed plate 22, and at the moment, a small-distance sand leakage opening is formed between the gate plate 28 and the upper toothed plate 22, so that sand in the sand silo 4 falls into the sand box 29 below from the sand outlet 27 and the sand leakage opening.

Meanwhile, as shown in fig. 8, the gear B20 rotating clockwise drives the lower toothed plate 17 to move toward the push plate 32, the sliding plate 38 moving synchronously with the lower toothed plate 17 drives the sliding rod 33 and the rack 37 to move together, and the sliding block 35 blocks the push plate 32, so the pressure spring a 34 is gradually compressed.

When the sand leaking opening is completely moved away from the sand outlet 27 by the synchronously moving gate plate 28 and the upper toothed plate 22, the sand outlet 27 is blocked by the gate plate 28; the compression amount of the pressure spring a 34 gradually compressed at this time is already large. Subsequently, the continuously moving sliding plate 38 drives the rack 37 and the D gear 50 to rotate, the D gear 50 drives the winding wheel 25 to rotate through a shaft to gradually wind the pulling rope 36, the pulling rope 36 pulls the sliding block 35 to move downwards, and the B pressure spring 51 is compressed; when the downward-moving slide block 35 does not block the push plate 32 to move any more, the A pressure spring 34 with a large compression amount releases energy instantly to enable the push plate 32 to move away from the slide plate 38 in a rapid mode. The push plate 32 instantaneously transmits a strong pushing force to the sandbox 29 through the a cushion 31, and the push plate 32 pushes the sandbox 29 to fly out along the inclined guide rail 24 at an extremely fast speed. When the slide block 35 no longer obstructs the movement of the push plate 32, the B electric driver 15 is stopped to continue driving the B gear 20 to rotate clockwise, and the sand leakage opening between the shutter plate 28 and the upper toothed plate 22 is not in the area of the sand outlet 27; because the B gear 20 stopping clockwise rotation no longer drives the lower toothed plate 17 to move, under the restoring force of the a compressed spring 34, the push plate 32 stops moving forward when moving to the front end of the B cross guide rail 18 in the direction away from the sliding plate 38, and at this time, the rear end surface of the sandbox 29 still fits with the a cushion 31. After the push plate 32 stops pushing the sandbox 29, the sandbox 29 with the advanced powerful energy continues to fly out along the inclined guide rail 24.

During the process that the sand box 29 flies out along the inclined guide rail 24, the sand in the sand box 29 has a tendency to move towards the rear end of the sand box 29 due to the inertia of the instantaneous movement of the sand box 29, and the sand separated in the sand box 29 is not accumulated towards the rear end of the sand box 29 because the swinging plate 46 is blocked by the corresponding stop 48, and the sand in the sand box 29 is still separated. Next, the sandbox 29 which is no longer pushed continues to fly outwards along the inclined rails 24 by virtue of strong inertia, and the rollers 44 and the striking strips 30 which follow the movement of the sandbox 29 slide in the respective inclined rails 24; when the impact strip 30 impacts the B cushion pad 45 at the front end of the inclined guide rail 24, under the rebound action, the sand box 29 moves towards the rear end direction of the inclined guide rail 24, so that the sand with forward movement kinetic energy is thrown out of the sand box 29 under the inertia action and falls into a fire area to extinguish fire; when the separated sand is thrown out of the sand box 29, the separated sand can give a large pushing force to the swinging plate 46 positioned in front of the sand box, the swinging plate 46 can swing a large angle in a direction away from the rear end of the sand box 29, and the plate spring 47 is compressed, so that the sand can be thrown out of the originally separated area; after the sand is thrown from the sand box 29, the swinging plate 46 swings and resets to the initial state under the resetting action of the plate spring 47.

When the rebounded sandbox 29 rapidly moves towards the rear end direction of the inclined guide rail 24, the sandbox 29 collides with the A buffer 31 on the push plate 32, the push plate 32 moves backwards, and the A pressure spring 34 is compressed to a certain degree to buffer the impact of the sandbox 29; the strong rebound force can make the sandbox 29 and the A cushion 31 collide and rebound again, after the sandbox 29 and the A cushion 31 collide and rebound for a plurality of times, the sandbox 29 consumes all kinetic energy and is attached to the A cushion 31 again. Under the action of the gravity of the sandbox 29, the rear end face of the sandbox 29 moves along with the push plate 32 along with the A cushion 31 and is reset to the initial state.

After the sand box 29 finishes rebounding movement, the B electric driver 15 is controlled to drive the B gear 20 to rotate anticlockwise, the B gear 20 rotating anticlockwise drives the upper toothed plate 22 to move towards the gate plate 28, the end block 42 moving synchronously with the upper toothed plate 22 is attached to one end, having the L-shaped block 41, of the gate plate 28 after moving for a short distance, then the upper toothed plate 22 pushes the gate plate 28 to move synchronously, and at the moment, a sand leakage opening is formed between the gate plate 28 and the upper toothed plate 22, so that the sand leakage opening does not exist any more. During the movement of the synchronously moving shutter plate 28 and the upper toothed plate 22 from one side of the sand outlet 27 to the other side, the sand outlet 27 is always blocked, so that the sand in the sand silo 4 does not fall into the sand box 29 below when the sand box 29 is reset to the initial state. During the process, the winding B gear 20 rotating anticlockwise drives the lower toothed plate 17 to move and reset, the lower toothed plate 17 drives the sliding plate 38, the A pressure spring 34, the rack 37 and the sliding rod 33 to move and reset, and the A pressure spring 34 pulls the push plate 32 to move and reset; when the reset rack 37 is disengaged from the D gear 50, the inclined end of the slider 35 protrudes out of the square cylinder 26 again under the reset action of the B compression spring 51, and the slider 35 pulls the pull rope 36 to release from the winding wheel 25. In the process that the A pressure spring 34 pulls the push plate 32 to move and reset, the push plate 32 extrudes the inclined surface of the slide block 35 and goes over the slide block 35, so that the slide block 35 moves downwards again to enable the B pressure spring 51 to be compressed again; when the push plate 32 passes over the slide block 35, the slide block 35 is moved and reset by the reset force of the B compression spring 51.

When the counterclockwise B gear 20 drives the push plate 32, the slide plate 38, the gate plate 28, the upper toothed plate 22, the lower toothed plate 17 and the sand box 29 to return to the initial state, the B electric driver 15 is controlled again to drive the B gear 20 to rotate clockwise. The above procedure of filling sand into the sand box 29 and throwing away the sand is repeated.

After sand throwing mechanism 55 extinguishes the fire near the device through sand throwing many times, when the fire far away needs to be continuously extinguished, when the device does not need to be subjected to position adjustment, only displacement mechanism 2 needs to be controlled to enable sand throwing mechanism 55 to be located at different heights, and then the fire far away can be extinguished. Since the sand-throwing point of the sand-throwing mechanism 55 is also moved upward after the upward movement, the sand thrown by the sand-throwing mechanism 55 can cover the distant fire. The height adjustment of the sand slinger 55 can be adjusted according to the actual distance of the fire at a distance.

Procedure of height adjustment of the platform 3 by the displacement mechanism 2: the A electric driver 7 is controlled to drive the A gear 8 to rotate forwards, the A gear 8 drives the two C gears 10 to rotate forwards through the corresponding idler 9, the C gears 10 drive the two screws 5 to rotate forwards, and the screw sleeves 13 drive the platform 3 to move upwards along the axes of the screws 5 under the matching of the screws 5 rotating forwards and the threads of the corresponding screw sleeves 13. The A electric driver 7 is controlled to drive the A gear 8 to rotate reversely, the A gear 8 drives the two C gears 10 to rotate reversely through the corresponding idler wheels 9, the C gears 10 drive the two screws 5 to rotate reversely, and the screw sleeves 13 drive the platform 3 to move downwards along the axes of the screws 5 under the matching of the reversely rotated screws 5 and the threads of the corresponding screw sleeves 13.

In the invention, the sand box 29 separates the sand in the sand box 29 by using a plurality of swinging plates 46 and finally throws the separated sand out, and the design has the advantages that: the sand in the sand box 29 is not accumulated together in the process of being thrown away, so that the thrown sand can be uniformly sprinkled on the flame, the area to be covered by the sand is larger than the area to be covered by the sand which is not uniformly thrown away, and the fire is more favorably covered and extinguished.
