There is a limit ring 9, and the upper surface of the limit ring 9 and the bottom of the mounting plate 2 are fixedly connected with a connecting column 10. The front and rear sides of the inner wall of the outer cylinder 7 are fixedly connected with the inner cylinder 11, and the inner wall of the inner cylinder 11 is fixedly connected with a partition plate 12. The surface of the inner cylinder 11 is fitted with a slip ring 13, and grooves 14 are provided on the left and right sides of the inner wall of the slip ring 13. Rubber blocks 15 are bonded on the left and right sides of the inner cylinder 11, and the surface of the rubber block 15 is fitted with the inner wall of the groove 14. The friction between the rubber block 15 and the slip ring 13 is greater than the gravity of the slip ring 13. The bottom of the mounting plate 2 is fixedly connected with a toggle mechanism 16.

[0032] The dialing mechanism 16 comprises a first stepper motor 161, a threaded column 162, a threaded cylinder 163, a dialing block 164, a bearing 165 and a hollow block 166, the upper surface of the first stepper motor 161 is fixedly connected with the bottom of the mounting plate 2, the output end of the first stepper motor 161 is fixedly connected with one end of the threaded column 162, the surface of the threaded column 162 is threadedly connected with the inner wall of the threaded cylinder 163, the surface of the threaded cylinder 163 is fixedly connected with the inner wall of the dialing block 164, the upper surface of the dialing block 164 is attached to the bottom of the mounting plate 2, the inner ring of the bearing 165 is fixedly connected with the surface of the threaded column 162, the outer ring of the bearing 165 is fixedly connected with the inner wall of the hollow block 166, and the upper surface of the hollow block 166 is fixedly connected with the bottom of the mounting plate 2.

[0033] The upper and lower sides of the inner wall of the slip ring 13 and the left and right sides of the inner wall of the inner cylinder 11 are attached with fire extinguishing balls 17 between the front and rear two partition plates 12.

[0034] It should be noted that the distance between the base 4 and the mounting plate 2 can be controlled by the electric telescopic rod 3, and when the limiting ring 9 is sleeved on the outer cylinder 7, the outer cylinder 7 can be fixed on the base 4 through the cooperation of the limiting ring 9 and the horizontal plate 8, and when the limiting ring 9 is separated from the outer cylinder 7, the outer cylinder 7 can be directly taken off from the base 4.

[0035] When the groove 14 on the slip ring 13 is in contact with the rubber block 15, and the inner wall in the slip ring 13 is in contact with the surface of the fire extinguishing ball 17, the slip ring 13 cannot move through the friction between the slip ring 13 and the rubber block 15, and the fire extinguishing ball 17 is clamped between the front and rear two partition plates 12 through the slip ring 13, and the fire extinguishing ball 17 in the inner cylinder 11 is separated by the partition plate 12.

[0036] When the first stepper motor 161 drives the threaded column 162 to rotate, the dialing block 164 moves horizontally through the cooperation of the threaded column 162 and the threaded cylinder 163, and the dialing block 164 pushes the slip ring 13 to slide on the inner cylinder 11, and when the slip ring 13 is misaligned with the fire extinguishing ball 17, the fire extinguishing ball 17 automatically falls from the inner cylinder 11.

[0037] As shown in Figures 1 to 13 The upper surface of the base 4 is fixedly connected with a moving mechanism 18, and the upper surface of the moving mechanism 18 is attached to the bottom of the horizontal plate 8.

[0038] The moving mechanism 18 comprises a second stepper motor 181, a rotating shaft 182 and a rubber sleeve 183, the bottom of the second stepper motor 181 is fixedly connected with the upper surface of the base 4, the output end of the second stepper motor 181 is fixedly connected with one end of the rotating shaft 182, the surface of the rotating shaft 182 is adhesively connected with the inner wall of the rubber sleeve 183, and the upper surface of the rubber sleeve 183 is attached to the bottom of the horizontal plate 8.

[0039] It should be noted that, through the second stepper motor 181, the rubber sleeve 183 can be rotated around the rotating shaft 182. At the same time, when the rubber sleeve 183 rotates, the friction between the rubber sleeve 183 and the horizontal plate 8 can make the outer cylinder 7 and the U-shaped plate 6 in close contact, and make the outer cylinder 7 and the limiting ring 9 precisely aligned. Then, through the moving mechanism 18, when the limiting ring 9 is sleeved on the outer cylinder 7, the outer cylinder 7 will not be crushed by the limiting ring 9 due to the outer cylinder 7 not being aligned with the limiting ring 9.

[0040] The working principle of the present invention is as follows: first, the distance between the mounting plate 2 and the base 4 is adjusted to the maximum value by the electric telescopic rod 3, then, the outer cylinder 7 equipped with the fire extinguishing ball 17 is placed in the U-shaped plate 6, and the outer cylinder 7 is aligned with the limit ring 9 through the U-shaped plate 6, then, by turning on the second stepper motor 181, the rubber sleeve 183 is rotated, and the friction between the rubber sleeve 183 and the cross plate 8 can make the outer cylinder 7 and the U-shaped plate 6 in close contact. At this time, the limit ring 9 can be sleeved on the outer cylinder 7 without displacement of the outer cylinder 7, which will cause the outer cylinder 7 to be misaligned with the limit ring 9.

[0041] Then, the electric telescopic rod 3 is used to sleeve the limiting ring 9 on the outer tube 7, and the bottom of the limiting ring 9 is in contact with the transverse plate 8. At this time, the outer tube 7 can be fixed on the base 4 through the cooperation of the limiting ring 9 and the transverse plate 8.

[0042] Then, the drone body 1 is remotely controlled to hover at a designated position, and then the threaded column 162 is driven to rotate by the first stepper motor 161, and the toggle block 164 is moved horizontally through the cooperation of the threaded column 162 and the threaded cylinder 163. At this time, the horizontally moving toggle block 164 pushes the slip ring 13 to slide on the inner cylinder 11. When the slip ring 13 is offset from the fire extinguishing ball 17, the fire extinguishing ball 17 automatically falls from the inner cylinder 11.

[0043] After the fire extinguishing balls 17 are released, the remote-controlled drone body 1 lands at the take-off and landing point. Then, the distance between the mounting plate 2 and the base 4 is adjusted to the maximum value through the electric telescopic rod 3, and the limit ring 9 is separated from the outer tube 7. At this time, the outer tube 7 can be removed from the base 4.

[0044] Then, the outer cylinder 7 equipped with the fire extinguishing ball 17 is placed in the U-shaped plate 6, and the outer cylinder 7 is aligned with the limiting ring 9 through the U-shaped plate 6, then the rubber sleeve 183 is rotated by opening the second step motor 181, and the outer cylinder 7 is in close contact with the U-shaped plate 6 through the friction between the rubber sleeve 183 and the horizontal plate 8, at this time, the limiting ring 9 can be sleeved on the outer cylinder 7 without being misaligned with the outer cylinder 7 due to displacement of the outer cylinder 7, then the limiting ring 9 is sleeved on the outer cylinder 7 through the electric telescopic rod 3, and the bottom of the limiting ring 9 is in contact with the horizontal plate 8, at this time, the outer cylinder 7 is fixed on the base 4 through the cooperation of the limiting ring 9 and the horizontal plate 8.

[0045] When it is needed to equip the fire extinguishing ball 17 in the inner cylinder 11, the sliding ring 13 is aligned with the partition plate 12 by moving the sliding ring 13, then the fire extinguishing ball 17 is placed between the front and rear partition plates 12, and the sliding ring 13 is located in the middle of the fire extinguishing ball 17 by moving the sliding ring 13, at this time, the sliding ring 13 cannot be moved through the friction between the sliding ring 13 and the rubber block 15, and the fire extinguishing ball 17 is clamped between the front and rear partition plates 12 through the sliding ring 13.

[0046] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application, if no special description and limitation, are implemented according to the conventional means in the art.
