[0071] like Figure 5As shown, optionally, the first support member 81 includes two first support arms 811, and the second support member 82 includes two second support arms 812, and the two first support arms 811 are located between the two second support arms 812, thereby realizing the cross connection between the first support member 81 and the second support member 82, and also avoiding the first support member 81 and the second support member 82 from interfering with each other during the sliding process; the support base 83 is provided with a plurality of through areas, and the number of the through areas corresponds to the number of support components; the length of the through area is greater than the length of the first support arm 811 and the second support arm 812, so that when the lifting mechanism 8 is in the descending state, the first support member 81 and the second support member 82 can be completely in the through area, avoiding the interference of the support base 83 with the first support member 81 and the second support member 82, and also avoiding the first support member 81 and the second support member 82 protruding from the support base 83, so that the height occupied by the lifting mechanism 8 in the descending state is the thickness of the support base 83, which can reduce the space occupied by the lifting mechanism 8 in the descending state, further improve the space utilization rate, and avoid affecting the layout of other modules.

[0072] like Figure 5 As shown, the support base 83 includes a plurality of connecting beams 831, which are arranged parallel to each other and extend along the length direction of the support base 83. Two adjacent connecting beams 831 are respectively provided with first grooves 8311 with openings facing each other. A roller 84 is provided at one end of the second support arm 812. The roller 84 can slide along the first groove 8311, so that the second support member 82 can slide relative to the support base 83, and the height of the support platform 6 is also adjusted at the same time.

[0073] like Figure 7 As shown, optionally, the support platform 6 is provided with a longitudinal beam, which is arranged toward the support base 83, and the longitudinal beam extends along the length direction of the support platform 6. The longitudinal beam is provided with a second groove 61 in the direction of the frame of the support platform 6, and the two frame directions of the length direction of the support platform 6 are also provided with a second groove 61 in the direction of the longitudinal beam. A roller 84 is provided at one end of the first support arm 811, and the roller 84 can slide along the second groove 61, so that the first support member 81 can slide relative to the support platform 6, and the height of the support platform 6 is also adjusted.

[0074] like Figure 5 and 7As shown, optionally, a first driving member 85 is provided between the adjacent first support arm 811 and the second support arm 812, one end of the first driving member 85 is connected to the first support member 81, and the other end is connected to the second support member 82, and the connection position is higher than the position where the first support member 81 and the second support member 82 are rotatably connected; the first driving member 85 has a telescopic stroke, which is used to drive the first support member 81 and the second support member 82 to slide relative to the support platform 6 and the support base 83 respectively. When the first driving member 85 is extended, the extended end applies force to the second support member 82. At this time, using the principle of leverage, the sliding end of the second support member 82 will slide relative to the support base 83, and the sliding direction is to slide toward the first support member 81, and the same When the first support member 81 is rotatably connected with the second support member 82, the first support member 81 is pushed to slide synchronously, the first support member 81 slides toward the second support member 82 and the second support member 82 slides toward the first support member 81, and the lifting mechanism 8 is in an ascending state; when the first driving member 85 contracts, the first support member 81 can be pushed to slide away from the second support member 82 and the second support member 82 can be pushed away from the first support member 81 to slide, and the lifting mechanism 8 is in a descending state, thereby realizing the ascending or descending state of the lifting mechanism 8; in addition, the first driving member 85 is arranged in the gap between the adjacent first support arm 811 and the second support arm 812, so as to reduce the occupied volume and improve the space utilization.

[0075] like Figure 5 and 7 As shown, optionally, a limit member 86 is further provided between the adjacent first support arm 811 and the second support arm 812, and the limit member 86 is coaxially connected to one end of the first driving member 85, and when the first driving member 85 is gradually extending, the second supporting member 82 slides toward the first supporting member 81, and one end of the first supporting member 81 slides toward the second supporting member 82, but the first supporting member 81 and the second supporting member 82 must have a certain intersection angle to ensure the stability of the entire lifting mechanism 8. Therefore, when the first supporting member 81 and the second supporting member 82 slide to a certain position respectively, the first driving member 85 can abut against the limit member 86, and the limit member 86 limits the first driving member 85 from continuing to extend, thereby limiting the sliding position of the first supporting member 81 and the second supporting member 82, thereby meeting the stability of the lifting mechanism 8.

[0076] like Figures 8 to 10As shown, optionally, the ducted UAV 7 includes a support beam 71 extending in the longitudinal direction, and at least three ducted propulsion systems 72 are arranged on both sides of the width direction perpendicular to the length direction of the support beam 71. The ducted propulsion systems 72 are arranged on the support beam 71 so that the ducted UAV 7 as a whole extends along the length direction and has a longitudinal structure, so that the ducted UAV 7 can pass through narrow areas; at least three ducted propulsion systems 72 are arranged in the width direction of the support beam 71 to meet the power load, and a fire water cannon 73 is provided on the support beam 71. The fire water cannon 73 can be connected to a water hose to spray a fire extinguishing agent, so that the ducted UAV 7 can perform high-altitude firefighting.

[0077] like Fig. 9 As shown, optionally, four ducted propulsion systems 72 are provided on one side of the support beam 71, that is, the ducted UAV 7 of the present application is an eight-ducted UAV, of which three ducted propulsion systems 72 are connected to the support beam 71, and the three ducted propulsion systems 72 are configured as a first ducted propulsion system, a second ducted propulsion system and a third ducted propulsion system, which is equivalent to that three ducted propulsion systems 72 can be provided on one side of the support beam 71, thereby reducing the length of the ducted UAV 7 and improving space utilization; the second ducted propulsion system is located between the first ducted propulsion system and the third ducted propulsion system; the other ducted propulsion system is connected to the second ducted propulsion system and can be folded toward the second ducted propulsion system along a length direction perpendicular to the support beam 71, thereby further reducing the space in width of the ducted UAV 7 for convenient transportation, especially when the ducted UAV 7 is placed on a fire truck, it is beneficial to the placement of other components on the fire truck, so that the fire truck can be made smaller in width and length, making it easier for the fire truck to pass through narrow areas. The ducted UAV 7 of the present application reduces the length dimension while meeting the power load requirement, and is convenient for transportation and placement.

[0078] like Fig. 9 and 10 As shown, the ducted UAV 7 is also provided with a folding mechanism, by which the folding mechanism is provided to facilitate the folding of the ducted propulsion system 72, so that the ducted propulsion system 72 can be folded along the length or width direction, thereby reducing the space of the ducted UAV 7 for easy transportation and placement; the folding mechanism includes a first connecting member 10 and a second connecting member 11 that are rotatably connected, and the first connecting member 10 and the second connecting member 11 are respectively connected to the two ducted propulsion systems 72, so that the ducted propulsion system 72 can be rotated for easy folding; the folding mechanism also includes a driving component 12, and the driving component 12 is connected to the first connecting member 10 and the second connecting member 11. At the same time, the driving component 12 can drive the second connecting member 11 to flip relative to the first connecting member 10, thereby driving the ducted propulsion system 72 connected to the second connecting member 11 to flip, thereby realizing the folding of the ducted propulsion system 72.

[0079] like Fig.10 As shown, the first connecting member 10 is provided with a first through hole, and the driving assembly 12 includes a second driving member 121. The second driving member 121 is arranged at the position of the first through hole and is rotatably connected to the first connecting member 10, so that the second driving member 121 can rotate relative to the first connecting member 10; the second connecting member 11 is provided with a second through hole, and the driving assembly 12 also includes a rotating member 122. The rotating member 122 is arranged at the position of the second through hole and is rotatably connected to the second connecting member 11, so that the rotating member 122 can rotate relative to the second connecting member 11; the driving assembly 12 also includes a connecting rod 123, one end of the connecting rod 123 is threadedly connected to the rotating member 122, and the other end is connected to the second driving member 121. When the second driving member 121 drives the connecting rod 123 to rotate, the connecting rod 123 is threadedly connected to the rotating member 122, so that the rotating member 122 can rotate relative to the second connecting member 11. The movable member 122 moves toward or away from the second driving member 121. While driving the rotating member 122 to move, the rotating member 122 is rotationally connected to the second connecting member 11, which also drives the second connecting member 11 to flip relative to the first connecting member 10, thereby realizing the folding function of the ducted propulsion system 72. During the flipping of the second connecting member 11, the driving and rotating member 122 need to adjust the angle in real time. Therefore, the second driving member 121 and the rotating member 122 are rotationally connected to the first connecting member 10 and the second connecting member 11 respectively, so that the second driving member 121 can drive the rotating member 122 to rotate while adjusting the angle of the second driving member 121 and the rotating member 122 in real time, so that the second driving member 121 can better drive the rotating member 122 to move on the connecting rod 123, thereby facilitating the control of the folding mechanism and avoiding jamming.

[0080] like Fig.10As shown, the second driving member 121 is provided with a first connecting hole 1211, and the second driving member 121 is rotatably connected to the first connecting member 10 through the first connecting hole 1211. In this way, the second driving member 121 can rotate around the first connecting member 10 with the first connecting hole 1211 as the axis. At the same time, the second connecting member 11 can be flipped around the first connecting member 10 with the second connecting member 11 as the axis. The axis of the flipping position can be configured as the first axis. The axis of the first connecting hole 1211 is parallel to the first axis, and the axis of the connecting rod 123 is perpendicular to the first connecting hole 1211. In this way, when the second driving member 121 drives the connecting rod 123 to rotate, the second connecting member 11 is flipped, and the second driving member 121 is also rotated relative to the first connecting member 10 in real time through the first connecting hole 1211, so that the second driving member 121 maintains an angle corresponding to the rotating member 122 in real time, so as to better drive the rotating member 122; the rotating member 122 is provided with a second connecting hole, and the rotating member 122 is connected to the second connecting member 10 through the second connecting hole. 11 is rotatably connected, so that the rotating member 122 can rotate around the second connecting member 11 with the second connecting hole as the axis. At the same time, the second connecting member 11 can be flipped over by using the connection position of the first connecting member 10 and the second connecting member 11 as the axis. The axis of the flipping position can be configured as the first axis. The axis of the second connecting hole is parallel to the first axis, and the axis of the connecting rod 123 is perpendicular to the second connecting hole. In this way, when the second driving member 121 drives the connecting rod 123 to rotate, the second connecting member 11 is flipped over, and the connecting rod 123 is threadedly connected to the rotating member 122. The driving angle of the second driving member 121 changes, which also drives the changing angle of the rotating member 122 accordingly. The rotating member 122 also adjusts the rotation angle in real time through the second connecting hole to keep consistent with the second driving member 121, so that the second driving member 121 maintains the angle corresponding to the rotating member 122 in real time, so as to facilitate the second driving member 121 to better drive the rotating member 122, and further facilitate the realization of the folding function of the ducted propulsion system 72 to avoid jamming.

[0081] Optionally, the second driving member 121 may be a lead screw motor, the connecting rod 123 may be an electric lead screw, and the lead screw motor is connected to the electric lead screw to drive the electric lead screw to rotate. The first connecting hole 1211 may be provided on the lead screw motor housing, or the second driving member 121 may further include a housing connected to the lead screw motor, so as to avoid the first connecting hole 1211 affecting the normal operation of the lead screw motor.
