The fire control unmanned aerial vehicle fixing device can be fixed with the frame through the fixed plate, or can be fixed with the unmanned aerial vehicle take-off and landing platform through the fixed part. The pushing pieces 80 of the fire-fighting unmanned aerial vehicle fixing device can be provided with two groups, and each group of pushing pieces 80 simultaneously controls the linear motion of the two inserted bars 50 positioned on the same side, so that the time difference of multipoint fixing is reduced, the asynchronous motion of the inserted bars 50 is avoided, and the motion precision is ensured. Of course, only one set of pushers 80 may be provided to control the linear motion of all of the plungers 50.

According to the fire engine provided by the embodiment of the third aspect of the invention, the fire-fighting unmanned aerial vehicle fixing device on the fire engine completes the movement steering of the inserted link 50 through the movement matching among the first guide groove 20, the second guide groove 30 and the limiting stop point 520, and realizes the fixed matching of the inserted link 50 and the fire-fighting unmanned aerial vehicle. Specifically, the fire-fighting unmanned aerial vehicle body can be fixed through the landing gear 10, the grounding end of the landing gear 10 is provided with the plug-in part 110, the plug rod 50 can be arranged in the plug-in part 110 in a penetrating mode, and the fixing part 510 on the plug rod 50 can be pressed against the outer edge of the plug-in part 110 to fix the fire-fighting unmanned aerial vehicle. Firstly, the inserted link 50 is opposite to the plug-in part 110 on the landing gear 10, then the inserted link 50 moves towards the plug-in part 110, in the moving process, the limit stop point 520 on the inserted link 50 is embedded in the first guide groove 20 to move, when the limit stop point 520 moves to the position of the limit shift lever assembly 40, the inserted link 50 is penetrated into the plug-in part 110, at the moment, the limit shift lever assembly 40 is positioned at the first guide position, the first guide groove 20 is penetrated through the second guide groove 30, then the limit stop point 520 continuously slides towards the second guide groove 30, and as the first guide groove 20 and the second guide groove 30 are positioned in two intersecting planes, when the limit stop point 520 slides from the first guide groove 20 to the second guide groove 30, the first area where the first guide groove 20 and the second guide groove 30 are in engagement, further, the inserted link 50 also rotates, at the moment, the limit stop point on the inserted link 50 completely enters the second guide groove 30, the inserted link 50 completes rotation, at the moment, the fixed part 510 is opposite to the outer edge of the plug-in part 110, and at the moment, the outer edge of the second guide groove 30 is pressed against the outer edge 110, and the outer edge of the plug-in part 110 is pressed against the outer edge 110, and the outer edge of the plug-in the three-in part is pressed against the outer edge 110, thereby the fixed, and the outer edge of the plug-in part 110 is pressed against the outer edge 110, and the outer edge of the plug-in part is pressed against the fixed, and the outer edge 110, and the outer edge of the plug-in part is pressed. When the fixation needs to be released, the insert rod 50 moves towards the inserting portion 110, the fixing portion 510 is far away from the outer edge of the inserting portion 110, when the limit stop point 520 on the insert rod 50 passes through the first area from the second guide groove 30, the insert rod 50 can reversely rotate and then enter the first guide groove 20, then the insert rod 50 moves away from the inserting portion 110, when the limit stop point 520 passes through the position of the limit deflector rod assembly 40 again, the limit deflector rod assembly 40 is located at the second guide position, the first guide groove 20 and the second guide groove 30 are disconnected, the limit stop point 520 can continuously slide to the initial position along the first guide groove 20, so that the insert rod 50 is out of contact with the inserting portion 110, and the fixation of the fire-fighting unmanned aerial vehicle is released. The fire engine provided by the embodiment of the invention has high automation degree, can improve the fixing reliability of the fire unmanned aerial vehicle, and can better ensure the stability of the fire unmanned aerial vehicle in the transportation process.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
