[0031] Please refer to Figures 1-6 The utility model provides a technical scheme: a fire extinguishing ball throwing device, characterized by comprising containing box 1, first connecting piece, telescopic link 2, second connecting piece and memory spring 6, the containing box 1 includes bottom plate 14, the bottom plate 14 can be forward and backward sliding type setting in the lower end of containing box 1, the lateral wall of containing box 1 is equipped with the entrance, the first connecting piece rotatablely connects containing box 1, the rotation center line of first connecting piece is perpendicular to the sliding direction of bottom plate 14, the upper end of telescopic link 2 is hinged to bottom plate 14, and the lower end is fixedly connected with first connecting piece, the second connecting piece is connected with containing box 1, the both ends of memory spring 6 are connected with the lower end of first connecting piece and the lower end of second connecting piece respectively, the memory spring 6 can be CuZnAl memory alloy spring, and the memory spring 6 is used to pull the lower end of first connecting piece rearward.

[0032] When the fire extinguishing ball throwing device of the utility model is used, the fire extinguishing ball throwing device of the utility model can be installed on the unmanned aerial vehicle for use, specifically, the upper end of the containing box 1 is welded and fixed at the bottom of the unmanned aerial vehicle, that is, the installation of the fire extinguishing ball throwing device of the utility model on the unmanned aerial vehicle can be realized.

[0033] When the fire extinguishing ball throwing device of the utility model is in the initial state, the bottom plate 14 is in the state of completely closing the inner cavity lower end of containing box 1, the telescopic link 2 and the first connecting piece are in the vertical state, and the memory spring 6 is in the stretched state.

[0034] Before the unmanned aerial vehicle provided with the fire extinguishing ball launching device is used to extinguish fire, the fire extinguishing ball 13 is placed into the containing box 1 through the inlet, and the fire extinguishing ball 13 entering the containing box 1 can be supported on the bottom plate 14, and after the fire extinguishing ball 13 is loaded into the containing box 1, the unmanned aerial vehicle can be controlled to carry the fire extinguishing ball launching device provided with the fire extinguishing ball 13 to above the fire site.

[0035] After the unmanned aerial vehicle carries the fire extinguishing ball launching device provided with the fire extinguishing ball 13 to above the fire site, the height of the unmanned aerial vehicle is gradually lowered, the fire extinguishing ball launching device gradually approaches the flame as the height of the unmanned aerial vehicle is lowered, and the temperature at the position of the memory spring 6 gradually rises; when the temperature at the position of the memory spring 6 reaches a temperature at which the memory spring 6 can be shortened, the memory spring 6 is shortened and pulls the lower end of the first connecting piece backward, at this time, the first connecting piece can be rotated, the first connecting piece can drive the telescopic rod 2 to move forward, and the telescopic rod 2 can drive the bottom plate 14 to slide forward; after the bottom plate 14 slides forward by a certain distance, the fire extinguishing ball 13 loses the support of the bottom plate 14 and can fall into the fire site downward, and at this time, the launching of the fire extinguishing ball 13 can be completed.

[0036] With the structure, the fire extinguishing ball launching device can automatically launch the fire extinguishing ball 13 without manual control of the unmanned aerial vehicle.

[0037] After the fire extinguishing ball launching device launches the fire extinguishing ball 13, the unmanned aerial vehicle carrying the fire extinguishing ball launching device returns to the place where the fire extinguishing ball 13 is placed, at this time, the bottom plate 14 can be pushed backward to make the bottom plate 14 again completely close the lower end of the inner cavity of the containing box 1, the first connecting piece is rotated due to the backward sliding of the bottom plate 14, the memory spring 6 becomes soft and deforms because the temperature of the place where the fire extinguishing ball 13 is placed is lower than the temperature at which the memory spring 6 is shortened and deformed, at this time, the bottom end of the first connecting piece can pull the memory spring 6 to lengthen, and the memory spring 6 will not rebound after being lengthened, at this time, the fire extinguishing ball 13 can be loaded into the containing box 1 again to perform the next rescue.

[0038] In the embodiment, the containing box 1 is fixed with a shaft rod, the shaft rod is arranged perpendicular to the sliding direction of the bottom plate 14, the first connecting piece is provided with a first shaft hole, and the shaft rod is located in the first shaft hole and cooperates with the first shaft hole. With the structure, the first connecting piece can be rotatably connected to the containing box 1, and the rotation center line of the first connecting piece can be perpendicular to the sliding direction of the bottom plate 14.

[0039] In the embodiment, the telescopic rod comprises a sleeve and a round rod, the round rod is slidingly fitted in the sleeve, the lower end of the sleeve is connected with the upper end of the first connecting piece 31, and the upper end of the round rod is hingedly connected with the bottom plate 14.

[0040] In the embodiment, the fire extinguishing ball throwing device further comprises a plugging part, the plugging part is arranged on the containing box 1, and the plugging part is used for plugging the inlet.

[0041] After the fire extinguishing ball 13 is placed into the containing box 1 through the inlet, the plugging part plugs the inlet, and the possibility that the fire extinguishing ball 13 in the containing box 1 accidentally falls out of the inlet during flight of the unmanned aerial vehicle and carrying of the fire extinguishing ball throwing device can be reduced.

[0042] In the embodiment, the plugging part comprises a rotating rod 7, a baffle 8 and a torsional spring 9, the rotating rod 7 is fixedly connected with the containing box 1, one end of the baffle 8 is arranged in the inlet, the one end of the baffle 8 is rotatably connected with the rotating rod 7, the other end of the baffle 8 opposite to the one end abuts against the inner wall of the containing box 1, the torsional spring 9 surrounds the rotating rod 7, one end of the torsional spring 9 is connected with the baffle 8, and the other end of the torsional spring 9 is connected with the side wall of the containing box 1.

[0043] When the fire extinguishing ball 13 is placed into the containing box 1 through the inlet, the baffle 8 is rotatably connected with the rotating rod 7, the baffle 8 is pushed away towards the middle part of the inner cavity of the containing box 1, the fire extinguishing ball 13 can be thrown into the containing box 1 through the inlet, and the fire extinguishing ball 13 can be conveniently thrown into the containing box 1 through the inlet.

[0044] Since the torsional spring 9 surrounds the rotating rod 7, one end of the torsional spring 9 is connected with the baffle 8, and the other end of the torsional spring 9 is connected with the containing box 1, when the baffle 8 is pushed away, the torsional spring 9 is elastically deformed, after the fire extinguishing ball 13 is thrown into the containing box 1, the pushing force on the baffle 8 is removed, the baffle 8 is reset forward under the restoring force of the torsional spring 9, the baffle 8 is arranged in the inlet, the other end of the baffle 8 opposite to the one end abuts against the inner wall of the containing box 1, the baffle 8 cannot be rotated to the outside of the containing box 1, at this time, the baffle 8 can re-plug the inlet, and the plugging part can plug the inlet.

[0045] In the embodiment, the one end of the baffle 8 is formed with a second shaft hole, and the rotating rod 7 is located in the second shaft hole and matched with the second shaft hole. With the structure, the one end of the baffle 8 can be rotatably connected with the rotating rod 7.

[0046] In this embodiment, the upper surface of the back side of the bottom plate 14 is inclined downward to form a slope 10.

[0047] When the fire extinguishing ball 13 is placed on the bottom plate 14, the fire extinguishing ball 13 rolls to the lower part of the slope 10 due to gravity and stops on the bottom plate 14 after being resisted by the inner wall of the containing box 1. When the bottom plate 14 slides forward by a certain distance, the fire extinguishing ball 13 can quickly fall from the back side of the bottom plate 14, and the fire extinguishing ball 13 is more easily separated from the bottom plate 14.

[0048] In this embodiment, the lower end of the containing box 1 is provided with connecting rods 11 perpendicular to the sliding direction of the bottom plate 14. The two connecting rods 11 are provided with upper sides located on the same horizontal plane, and the upper sides of the two connecting rods 11 abut the bottom of the front end of the bottom plate 14. The lower end surface of the front side plate of the containing box 1 abuts the upper side of the bottom plate 14.

[0049] Because the lower end of the containing box 1 is provided with connecting rods 11 perpendicular to the sliding direction of the bottom plate 14, the two connecting rods 11 are located on the same horizontal plane, and the upper parts of the two connecting rods 11 abut the bottom of the side of the bottom plate 14 close to the first connecting piece, the bottom plate 14 can slide forward and backward on the connecting rods 11. Because the front side of the containing box 1 abuts the upper side of the bottom plate 14, the bottom plate 14 will not overturn during the forward and backward sliding process on the connecting rods 11. With this structure, the bottom plate 14 can be arranged at the lower end of the containing box 1 in a forward and backward sliding manner.

[0050] In this embodiment, the rear end of the bottom plate 14 is connected with a limiting strip 12.

[0051] When the bottom plate 14 slides forward by a certain distance, the front side of the limiting strip 12 can abut the rear connecting rod 11 of the two connecting rods 11. At this time, the bottom plate 14 cannot continue to slide forward. With this structure, the possibility of the bottom plate 14 being separated from the containing box 1 during the sliding process is reduced.

[0052] In this embodiment, the first connecting piece and the second connecting piece can be structures that can stretch and retract in the vertical direction.

[0053] When the fire extinguishing ball throwing device needs to put in the fire extinguishing ball 13, the first connecting piece and the second connecting piece can be shortened to the height that the person can put the fire extinguishing ball 13, so that the fire extinguishing ball 13 is conveniently put into the containing box 1; when the device is moved to the scene where the rescue needs to be carried out, the first connecting piece and the second connecting piece can be elongated, the height difference of the memory spring 6 to the unmanned aerial vehicle can be increased, that is, the unmanned aerial vehicle can be higher than the memory spring 6 by a larger distance, the temperature difference between the height position of the unmanned aerial vehicle and the position of the memory spring 6 can be increased, and when the temperature at the position of the memory spring 6 reaches the temperature that can make the memory spring 6 shorten, the possibility that the unmanned aerial vehicle is baked and damaged can be reduced.

[0054] In the embodiment, the first connecting piece comprises a first rod body 31 and a second rod body 32, the first rod body 31 is internally provided with a first hole, and the second rod body 32 is slidingly matched in the first hole; the second connecting piece comprises a third rod body 33 and a fourth rod body 34, the third rod body 33 is internally provided with a third hole, and the fourth rod body 34 is slidingly matched in the third hole; and the two ends of the memory spring 6 are respectively connected with the lower end of the second rod body 32 and the lower end of the fourth rod body 34.

[0055] In the embodiment, the second rod body 32 is connected with a second limiting block 42 at the upper end, the second limiting block 42 is slidingly matched in the first hole, the inner side wall of the lower end of the first hole is connected with a first limiting ring 51, the second rod body 32 is matched in the first limiting ring 51, and the upper side surface of the first limiting ring 51 abuts against the lower side surface of the second limiting block 42.

[0056] The fourth rod body 34 is connected with a fourth limiting block 44 at the upper end, the fourth limiting block 44 is slidingly matched in the third hole, the inner side wall of the lower end of the third hole is connected with a third limiting ring 53, the fourth rod body 34 is matched in the third limiting ring 53, and the upper side surface of the third limiting ring 53 abuts against the lower side surface of the fourth limiting block 44.

[0057] In this structure, the first connecting piece and the second connecting piece can be vertically telescopic.

[0058] In the embodiment, the projection of the memory spring 6 on a horizontal plane is located outside the projection range of the bottom plate 14 on the horizontal plane.

[0059] In this structure, when the fire extinguishing ball 13 falls, the probability that the fire extinguishing ball 13 hits the memory spring 6 can be reduced, and the possibility that the unmanned aerial vehicle carrying the fire extinguishing ball throwing device loses balance due to the fire extinguishing ball 13 hitting the memory spring 6 can be reduced.

[0060] The utility model discloses still provided another technical scheme: a fire rescue unmanned plane, including above-mentioned fire extinguishing ball delivery device.

[0061] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the utility model and are not limited. Although the utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the utility model, and all should be covered in the claim range of the utility model.
