Detailed Description

The following detailed description of the present invention will be made in conjunction with the accompanying drawings and specific embodiments.

As shown in fig. 1, 2, 3 and 4, the folding canopy special for the helicopter comprises: air park 1 the outside of air park 1 is provided with annular base 2 the upper end bilateral symmetry of annular base 2 is provided with fan-shaped folding rain-proof unit 3, two fan-shaped folding rain-proof units 3 form a hemisphere canopy, fan-shaped folding rain-proof unit 3's structure includes: initiative arc folding leg 31 and a plurality of driven arc folding legs 32 of setting between initiative arc folding leg 31 and annular base 2, the both ends of initiative arc folding leg 31 and driven arc folding leg 32 rotate the setting on annular base 2 through pivot 33 respectively, be connected through fan-shaped rain cloth 34 between this stack of frame 31 of initiative arc, this stack of frame 32 of driven arc and the annular base 2 the bilateral symmetry of annular base 2 is provided with the collapsible strutting arrangement group who is connected with fan-shaped folding rain-proof unit 3, include two collapsible support unit 4 in the collapsible strutting arrangement group, collapsible support unit 4's structure includes: the folding device comprises a support 41 fixedly arranged on the annular base 2, sliding grooves 42 are symmetrically arranged on two sides of one end of the support 41, a first sliding rod 43 matched with the sliding grooves 42 is arranged in the sliding grooves 42 in a sliding mode, a first folding air cylinder 44 is rotatably arranged on the first sliding rod 43 through a first rotating block 45, a piston rod 441 of the first folding air cylinder 44 is movably connected with the driving arc-shaped folding frame 31 through a pin shaft 46, a second sliding rod 47 is arranged inside the other end of the support 41, a second folding air cylinder 48 is rotatably arranged on the second sliding rod 47 through a second rotating block 49, and a piston rod 481 of the second folding air cylinder 48 is rotatably arranged on the first sliding rod 43 through a third rotating block 50.

When the special folding canopy for the helicopter is used, the helicopter stops on the parking apron 1, the first folding cylinders 44 in the four folding supporting units 4 are simultaneously started, the piston rods 441 of the first folding cylinders 44 push the driving arc-shaped folding frames 31 to move upwards for unfolding, the piston rods 441 simultaneously rotate on the driving arc-shaped folding frames 31 through the pin shafts 46, when the driving arc-shaped folding frames 31 move upwards, the driven arc-shaped folding frames 32 are driven to move upwards together until the fan-shaped rain shielding cloth 34 is completely unfolded, the fan-shaped rain shielding cloths 34 in the two fan-shaped folding rain shielding units 3 are completely unfolded to form a hemispherical rain shielding canopy for covering the helicopter in the parking apron 1, and a certain gap exists when the fan-shaped rain shielding cloths 34 in the two fan-shaped folding rain shielding units 3 are completely unfolded and combined together, at the moment, the second folding cylinders 48 in the four folding supporting units 4 are simultaneously started, a piston rod 481 of the second folding cylinder 48 drives a third rotating block 50 to move towards the direction of the merging center of the two fan-shaped rain shields 34, the third rotating block 50 drives a first sliding rod 43 to slide towards the direction of the merging center of the two fan-shaped rain shields 34 in the sliding groove 42, the first sliding rod 43 drives a first folding cylinder 44 to move towards the direction of the merging center of the two fan-shaped rain shields 34 through a first rotating block 45, so that the two fan-shaped rain shields 34 are further pushed to merge together to realize gapless merging, and at the moment, the hemispherical rain shelter can shield rain for a helicopter; can install annular base 2 in the recess of air park 1 outside below ground at the in-process of installation, can leave in below ground after the canopy is folded, make things convenient for the transport vechicle to stride annular base 2 and reach the optional position on air park 1, it is convenient to transport.
