Description

Technical Field

[0001] The utility model relates to the technical field of artificial rainfall aircraft, in particular to a gliding rain enhancement bomb. Background Art

[0002] In recent years, with the rapid development of agricultural demand and unmanned aerial vehicle (UAV) technology, UAVs have been increasingly widely used in special scenarios such as search and rescue, patrol, rescue, and riot control. In particular, UAVs can also be used to perform artificial rainfall operations.

[0003] Existing artificial rainfall UAVs use UAVs to carry catalyst shells. When the UAV flies to the designated rainfall position, the UAV penetrates the cloud layer and fires the catalyst shell, thereby putting catalysts such as silver iodide and dry ice into the cloud layer to achieve artificial rainfall. This method requires the UAV to fly into the cloud layer, and the UAV is prone to malfunction due to water vapor.

[0004] In addition, in the method of artificial rainfall by rocket bombs, after the rocket bombs perform rainfall enhancement, they have a relatively high speed and are prone to danger when landing. Summary of the Utility Model

The front fixed ring is hinged to the front side wall of the lifting connecting frame through a lifting frame. The tail of the lifting connecting frame is hinged to the rear fixed ring.

[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0021] Please refer to Figures 1 to 6 , a gliding rain enhancement projectile, including a projectile body 1, a telescopic wing frame 2, a center of gravity seat 3, an endurance motor 4, and a flight wing 5. Chemical substances such as silver iodide and dry ice for rain enhancement are provided inside the projectile body 1. The telescopic wing frame 2 is foldably arranged on the projectile body 1. The center of gravity seat 3 is arranged between the projectile body 1 and the telescopic wing frame 2. The endurance motor 4 is arranged on the telescopic wing frame 2. The flight wing 5 is wrapped on the telescopic wing frame 2 and unfolds with the telescopic wing frame 2. The flight wing 5 is made of flexible cloth.

[0022] The utility model provides a gliding rain enhancement bomb that is launched by air-based means and uses a endurance motor 4 and a flight wing 5 to stay in the air for a long time. The rain enhancement bomb involved in the utility model has a simple structure, is convenient for production and manufacturing, and has a low manufacturing cost. In addition, in addition to the advantage of sufficient rainfall brought by staying in the air for a long time, when the gliding rain enhancement bomb lands, its speed is slow and it is safer.

[0023] The telescopic wing frame 2 includes a main frame 21, a fixed ring 22, a lifting frame 23, a lifting connecting frame 24, a side frame 25, a connecting frame 26 and a hinge head 27. A fixed ring 22 is respectively arranged at the front and rear of the main frame 21. The bomb body 1 is sleeved in the fixed ring 22. The fixed ring 22 at the front is hinged to the front side wall of the lifting connecting frame 24 through the lifting frame 23. The tail of the lifting connecting frame 24 is hinged to the fixed ring 22 at the rear. A hinge head 27 is also arranged at the front of the lifting connecting frame 24. The front parts of the two side frames 25 are respectively hinged to both sides of the hinge head 27. The middle parts of the two side frames 25 are both hinged to the middle part of the lifting frame 23 through a connecting frame 26. The middle part of the connecting frame 26 is for the endurance motor 4 to be arranged. The lifting connecting frame 24 and the connecting frame 26 are both composed of two mutually hinged rods.

[0024] A counterweight plate 30 is also arranged on the center of gravity seat 3. A storage battery can also be arranged on the counterweight plate 30. The storage battery is connected to the endurance motor 4 and provides a longer staying time for the rain enhancement bomb.

[0025] The rain enhancement method using the gliding rain enhancement bomb has the following steps:

[0026] Step 1: Load the gliding rain enhancement bombs side by side on the rotorcraft and make preparations before takeoff;

[0027] Step 2: Select the artificial rain enhancement area according to the cloud layer, and the rotorcraft takes off to the outer edge of the rain enhancement area;

[0028] Step 3: The rotorcraft launches the rain enhancement bombs along the outer edge of the artificial rain enhancement area;

[0029] Step 4: The rotorcraft lands, the rain enhancement bombs unfold the flight wings 5 and glide into the artificial rain enhancement area, and the rain enhancement bombs release the chemical substances for rain enhancement in the bomb body 1, and the artificial rain enhancement starts;

[0030] Step 5: The rain enhancement bombs land after gliding.

[0031] The advantage of this method is that the rain enhancement work has a fast reaction speed, can make full use of the cloud layer height for sufficient rain enhancement, and does not require the rotorcraft to fly into the cloud layer, and the rain enhancement process is safer.

[0032] In addition, after installing a flight control system in the head of the bomb body 1 of the gliding rain enhancement bomb, the rain enhancement bomb can be further controlled to land at a fixed point.
