[0001] The present invention relates to the technical field of flying equipment, and in particular to a flying high-altitude platform. Background Art

[0002] A flying high altitude platform is a flying device that can fly to a specified altitude to perform high-altitude operations.

[0003] In the prior art, the method of high-altitude work is mostly for workers to fix a lifting rope on the roof, and then lift the workers to the designated location to work. The operation process is relatively cumbersome. However, with the development of science and technology, flying equipment can replace manual labor to complete some high-altitude work tasks, that is, operating tools are installed on the flying equipment, and the workers operate the flying equipment to fly to the designated location to work, thereby improving work efficiency.

[0004] The types of high-altitude operations that flying equipment performs instead of manual labor are usually simpler, and the results are not as good as those of manual labor. Therefore, in order to improve the efficiency and results of high-altitude operations, this field needs manned high-altitude flying equipment. Summary of the invention

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0027] See also Figure 1-3 The present invention provides a technical solution as follows: a flying high-altitude platform includes a main structure frame 1, which is a square frame with four closed panels on each side. A working platform 11 is arranged in the middle of the main structure frame 1, and the surface of the working platform 11 is lower than the upper surface of the main structure frame 1. A working guardrail 12 is arranged on one side of the working platform 11, and a safety rope fixing point is arranged on the working guardrail 12. The safety rope on the safety clothing of the operator can be tied to the safety rope fixing point; a sliding guardrail 13 is arranged on the other side of the working platform 11, and the sliding guardrail 13 is detachably connected to the main structure frame 1; a ladder 14 is arranged on the outer wall of the structure frame close to the sliding guardrail 13, for the operator to climb into the working platform 11; an air intake window 15 is provided on the side wall of the main structure frame 1 located on the upper side of the ducted fan 2, and an exhaust window 16 is provided on the side wall of the main structure frame 1 located on the lower side of the ducted fan 2.

[0028] Preferably, four ducted fans 2 are rotatably connected in the main structure frame 1, and the ducted fans 2 are horizontally arranged. A hydrogen fuel cell 17 is arranged in the main structure frame 1. A high-pressure hydrogen storage tank 18 is also arranged in the main structure frame 1. The high-pressure hydrogen storage tank 18 is used to supply hydrogen to the hydrogen fuel cell 17. Two lithium batteries 19 are arranged on one side of the hydrogen fuel cell 17. The hydrogen fuel cell 17 supplies power to the ducted fan 2 and charges the lithium battery 19 at the same time. The lithium battery 19 serves as a backup battery and is electrically connected to the ducted fan 2. When the hydrogen fuel cell 17 fails, it starts to supply power.

[0029] Preferably, the four ducted fans 2 include two forward fans 21 and two turning fans 22. The two forward fans 21 are diagonally arranged in the main structure frame 1, and the two turning fans 22 are located at another diagonal position. The rotation direction of the two forward fans 21 is parallel to the length direction of the workbench, and the rotation direction of the two turning fans 22 is perpendicular to the length direction of the workbench.

[0030] Preferably, a driving group 3 for driving the ducted fan 2 to rotate is provided in the main structural frame 1, and the driving group 3 includes four electric cylinders 31, and the four electric cylinders 31 are electrically connected to the hydrogen fuel cell 17 and the lithium battery pack 19 at the same time; the four electric cylinders 31 are respectively rotatably connected to the four inner walls of the main structural frame 1, and the telescopic rods of the four electric cylinders 31 are respectively rotatably connected to the outer walls of the four ducted fans 2, wherein the rotation direction of the telescopic rod of the electric cylinder 31 on the forward fan 21 is consistent with the rotation direction of the forward fan 21, and the rotation direction of the telescopic rod of the electric cylinder 31 on the steering fan 22 is consistent with the rotation direction of the steering fan 22; a control platform for controlling the opening and closing of the ducted fan 2 and the electric cylinder 31 is provided in the main structural frame 1.

[0031] When performing aerial work, the operator opens the sliding guardrail 13 and climbs to the working platform 11 via the ladder 14. The operator closes the sliding guardrail 13 and is protected by the working guardrail 12 and the sliding guardrail 13. The ducted fan 2 is started, and air flows in from the air inlet window 15 and out from the exhaust window 16, generating lift to drive the main structure frame 1 to fly, thereby bringing the operator to the specified height for work. There is no need for the operator to be suspended from the roof, nor is there a need for flying equipment to replace manual work, thereby improving the efficiency and effect of aerial work.

[0032] When the high-altitude flying platform needs to move forward or backward, the electric cylinder 31 on the forward fan 21 is started to drive the forward fan 21 to rotate a certain angle, so that the propulsion direction of the forward fan 21 is tilted, and a forward thrust is generated on the high-altitude flying platform to realize the forward or backward movement of the high-altitude flying platform; when the high-altitude flying platform turns, the electric cylinder 31 on the steering fan 22 is started to drive the steering fan 22 to rotate a certain angle, change the propulsion direction of the steering fan 22, and cause thrust on the side of the high-altitude flying platform, which works together with the forward fan 21 to realize the steering of the high-altitude flying platform. If only the steering fan 22 generates thrust, the lateral movement of the high-altitude flying platform can be realized.

[0033] Preferably, a baffle 151 is provided on one side of the air intake window 15 close to the working guardrail 12, for shielding the air holes of the air intake window 15 on that side; a guide plate 161 is provided in the main structure frame 1, and the guide plate 161 is an arc-shaped plate, and the guide plate 161 is located below the ducted fan 2. The baffle 151 can prevent dust and other debris on the construction side from being sucked into the air intake window 15 during high-altitude operations, and the guide plate 161 can guide the wind blown downward by the ducted fan 2 to the exhaust window 16 on the side, so as to prevent a large amount of dust from being blown up from the ground when the flying high-altitude platform takes off from the ground.

[0034] Preferably, an emergency parachute 4 is installed on the upper surface of the main structure frame 1. During high-altitude operations, when one or more ducted fans 2 are accidentally damaged and stop working, causing the flying high-altitude platform to lose its lifting force and start to descend, the emergency parachute 4 is activated to cushion the descent of the flying high-altitude platform to avoid injuries to the operators. At the same time, handrails are provided on both sides of the working platform 11. When the flying high-altitude platform rises or descends, the operators hold the handrails to facilitate standing firmly.

[0035] Preferably, a shock-absorbing pad is provided on the bottom wall of the main structural frame 1, so as to cushion the main structural frame 1 when the main structural frame 1 falls from a high altitude to the ground.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
