[0030] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See attached Figures 1 to 8 The utility model discloses an automatic locking and releasing device for lifting a forest fire extinguishing bucket by an aircraft, comprising a locking device 1, a receiving device 2, and a bucket body 3;

[0032] like Figures 1-2 As shown, the barrel body 3 is placed on the ground, the receiving device 2 is placed on the barrel body 3, and the locking device 1 falls on the receiving device 2 after falling down;

[0033] like Figures 1 to 8 As shown, during use, the barrel body 3 is filled with a large amount of water and placed on the ground, the receiving device 2 is fixed to the upper end of the barrel body 3, the conical connector 24 is connected to the universal ball head 26, the universal ball head 26 is connected to the stud bolt rod 27, the stud bolt rod 27 is connected to the lower cover plate 28, and the lower cover plate is connected to the sealing group 34 to seal the lower hole of the barrel body 3.

[0034] like Figures 1 to 8As shown, during use, the locking device 1 is connected with the hook at the bottom of the aircraft, the aircraft falls, and the locking device 1 falls on the receiving device 2. After the locking device 1 falls into place, the electric push rod 13 receives a signal and starts to operate. The push rod moves down to the end of the stroke, and pushes the lower cone 18 to the conical connector 24. After it is in place, it receives a signal, and the motor 14 rotates forward, driving the 152 gear 1 to rotate, driving the gear 2 153 to rotate, driving the upper turntable 151 to rotate, and driving the three upper locking pins 154 to move on the three arc grooves. After the upper locking pin 154 moves to the other end of the arc groove, the front end of the upper locking pin 154 moves into the groove of the upper cylinder 22, which plays a locking connection role; the lower locking disk 17 rotates simultaneously with the upper retracting disk 15. After the lower locking disk 17 is in place, it is locked in the internal groove of the conical connector 24, which plays a locking connection role.

[0035] like Figures 1 to 8 As shown, during use, after the locking device 1 and the receiving device 2 are locked, the aircraft receives a signal to lift the device and take off. After arriving at the destination, the pilot presses the switch, and the electric push rod 13 retracts the push rod to the zero position of the stroke. Due to the locking connection of the lower locking plate 17, the electric push rod 13 drives the lower cover plate 28 to move up, and water flows out from the lower hole of the barrel body 3. After the water is released, the aircraft returns to the water intake point. After the barrel body 3 lands, the pilot presses the reset button, and the push rod of the electric push rod 13 moves down to the end of the stroke, driving the conical connector 24 back to its original position, and the motor 14 reverses, driving the upper locking plate 15 and the lower locking plate 17 to reverse and unlock. After unlocking in place, the pilot receives a signal to take off, and the aircraft drives the locking device 1 to take off together, and goes to the next receiving device 2 and the barrel body 3 to continue lifting the device to release water in the air.

[0036] To sum up, the utility model is an automatic locking and water releasing device for lifting forest fire extinguishing water buckets by aircraft. The operation is simple, and can realize automatic lifting and locking operation, and can release a large amount of water in the air, thereby reducing work intensity and improving work efficiency, and overcoming the problem of being unable to reach the scene due to harsh environment and unchanged traffic.

[0037] It should be understood that the utility model does not limit its application to the detailed structure and arrangement of the components proposed herein. The utility model can have other embodiments and can be implemented and executed in a variety of ways. The aforementioned variations and modifications fall within the scope of the utility model.
