DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the application will be described below with reference to the drawings in the embodiments of the application.

[0025] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. Meanwhile, in the description of the application, the terms “first”, “second”, etc. are only used for distinguishing description, and cannot be understood as indicating or implying relative importance.

Since the driving member 22 is a worm gear motor and the worm gear motor itself has self-locking performance, the fixing member 21 can always remain in a locked state after the driving member 21 is driven to rotate, and will not be reset due to vibration during driving of the fire truck, nor will it be loose. Compared with the traditional butterfly bolt for fixing the fire unmanned aerial vehicle 8, the structure is more stable.

[0029] Alternatively, as a possible embodiment, the worm gear motor can be replaced by a common servo motor or a stepper motor, and accordingly, some self-locking structures such as ratchet and toothed structure need to be added. The self-locking of the fixing device after fixing the fire unmanned aerial vehicle 8 can be achieved, thereby reducing the problem of bolt loosening due to vibration. Those skilled in the art can make some structural adjustments and corresponding technical improvements according to actual conditions.

[0030] As shown in Figure 1 As an embodiment, the self-locking device 2 further comprises a connecting shaft 23, one end of which is connected with the driving member 22 and the other end of which passes through the fixing member 21, so that the connecting shaft 23 can drive the fixing member 21 to rotate.

[0033] Alternatively, the second support member 4 can be connected with the driving member 22, thereby increasing the fixing area of the driving member 22 and improving the stability of the driving member 22.

[0034] Alternatively, four support assemblies can be provided, corresponding to the number of support assemblies, and the support assemblies can be integrally formed with the support platform 1.

[0036] As shown in Figure 1As shown, as an embodiment, the fixing member 21 comprises fixing sleeves 212 and support portions 211, the fixing sleeves 212 are used to be sleeved on one end of the landing gear 81, so that the two fixing sleeves 212 located at the two ends of the length direction of the fire-fighting unmanned plane 8 can be sleeved on the two ends of the landing gear 81 respectively, the axial direction of the fire-fighting unmanned plane 8 is limited, the stability between the fire-fighting unmanned plane 8 and the support platform 1 is improved, and the shaking of the fire-fighting unmanned plane 8 is avoided; the support portion 211 is connected with the fixing sleeve 212, and the connecting shaft 23 penetrates through the support portion 211, so that the connecting shaft 23 can drive the support portion 211 to rotate together.

[0037] Optionally, the support portion 211 is integrally formed with the fixing sleeve 212, and the support portion 211 is in an arc-shaped structure, and the landing gear 81 is formed by welding a plurality of pipes.

[0038] As shown in the figure, Figure 1 As an embodiment, a plurality of accommodating spaces are arranged on the support platform 1, and each accommodating space is used to accommodate a ball 5. By arranging the balls 5, the balls 5 can support the fire-fighting unmanned plane 8, so that the fire-fighting unmanned plane 8 is not in direct contact with the support platform 1, the friction between the fire-fighting unmanned plane 8 and the support platform 1 is reduced, the take-off and landing of the fire-fighting unmanned plane 8 is facilitated, and the power output is reduced. In addition, since the balls 5 can roll, when the fire-fighting unmanned plane 8 contacts the balls 5 during take-off or landing, the rolling of the balls 5 will make the fire-fighting unmanned plane 8 form a sliding distance, so that the fire-fighting unmanned plane 8 can take off or land stably. At the same time, since the balls 5 are in sliding connection with the fire-fighting unmanned plane 8, if the landing position of the fire-fighting unmanned plane 8 deviates, the fire-fighting unmanned plane 8 can be moved, so that the fixing device can lock the fire-fighting unmanned plane 8.

[0039] Optionally, as a possible embodiment, the balls 5 can be replaced by rollers.

In addition, since the balls 5 can roll, when the fire-fighting unmanned plane 8 contacts the balls 5 during take-off or landing, the rolling of the balls 5 will make the fire-fighting unmanned plane 8 form a sliding distance, so that the fire-fighting unmanned plane 8 can take off or land stably. At the same time, since the balls 5 are in sliding connection with the fire-fighting unmanned plane 8, if the landing position of the fire-fighting unmanned plane 8 deviates, the fire-fighting unmanned plane 8 can be moved, so that the fixing device can lock the fire-fighting unmanned plane 8.

[0041] As shown in the figure, Figure 3 As an embodiment, the fixing device further comprises a support mechanism 7, the support mechanism 7 is connected with the support platform 1, and the support mechanism 7 is used to adjust the height position of the support platform 1, so that the fire-fighting unmanned plane 8 can be supported to a height exceeding the box body 9, and the take-off and landing of the fire-fighting unmanned plane 8 are facilitated.

By arranging the sliding plate 82 on the landing gear 81 and covering the upper surfaces of the at least two rolling balls 5, the contact area between the landing gear 81 and the rolling balls 5 can be improved, so that the fire unmanned aerial vehicle 8 can slide between the sliding plate 82 and the rolling balls 5, the take-off and landing of the fire unmanned aerial vehicle 8 are facilitated, and the landing gear 81 of the fire unmanned aerial vehicle 8 can be prevented from falling into the space between the adjacent two rolling balls 5 during the landing process. Meanwhile, since the sliding plate 82 and the rolling balls 5 are in sliding connection, if the landing position of the fire unmanned aerial vehicle 8 is deviated, the fire unmanned aerial vehicle 8 can be moved conveniently, so that the fixing device can lock the fire unmanned aerial vehicle 8.

[0045] Optionally, the number of the rolling balls 5 needs to ensure the structural strength of the support platform 1, so the rolling balls 5 cannot be arranged too densely.
