Abstract
The utility model discloses a protection device for a multi-rotor-wing unmanned plane. The protection device comprises a round protection frame, a plurality of connecting brackets and a plurality of two-way connectors, wherein the connecting brackets are in long plate-like structures, weight-reducing holes are formed in the middle parts of the connecting brackets, one end of each connecting bracket is fixed between the surface at the outer end of a frame and the lower end of a motor on the multi-rotor-wing unmanned plane, and one two-way connector is mounted on the surface at the other end of the frame; the two-way connectors are in round pipe-shaped structures, and the two ends of each two-way connector are arranged on the left and right sides of the connecting bracket; the round protection frame is a round rod and is inserted into the plurality of the two-way connectors. According to the protection device, a main body structure is made from a carbon fiber material, so that the strength is high and the weight is light; in addition, as propellers are all in the protection range of the round protection frame when rotating at a high speed, the propellers and a rotor wing fuselage can be prevented from being damaged under the buffer action of the round protection frame when the plane collides with a barrier such as a wall, the repair cost of the plane can be greatly reduced, people around can be protected, and the safety is good.
Description
Technical field
The utility model belongs to aeronautical technology field, particularly relates to a kind of many rotor wing unmanned aerial vehicles fender guard.
Background technology
At present, many rotor wing unmanned aerial vehicles taking photo by plane, a lot of fields such as rescue, forest fire protection, security protection are widely used, it is mainly comprised of rotor fuselage, multiple electric motors and multi-blade propeller, wherein cyclogyro has the frame that multi-disc is radial setting with it, every frame outer end upper surface is provided with a motor, and on the output shaft of every motor upper end, connects a vane propeller.But; there is following point in many rotor wing unmanned aerial vehicles of this structure: owing to generally there is no special fender bracket on this unmanned plane; therefore when indoor and outdoor is flown; the screw propeller of High Rotation Speed probably strikes on obstacle; so not only can cause larger damage to the physical construction of aircraft; thereby increase service expenditure, but also can cause no small potential safety hazard to people around.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of can reduce aircraft accidental damage probability, therefore can reduce service expenditure, and the good many rotor wing unmanned aerial vehicles fender guard of safety.
In order to achieve the above object, many rotor wing unmanned aerial vehicles fender guard that the utility model provides comprises circular fender bracket, a plurality of connection bracket and a plurality of bilateral adaptor union; Wherein connection bracket is the tabular structure of strip shape of being made by carbon fibre material, middle part is formed with lightening hole, one end of each connection bracket is fixed between the outer end face and motor lower end of a slice frame on many rotor wing unmanned aerial vehicles, and other end surface is provided with a bilateral adaptor union; Bilateral adaptor union is round tube shape structure, and its two ends are positioned at the left and right sides of connection bracket; Circular fender bracket is circular pin, is inserted in the inside of above-mentioned a plurality of bilateral adaptor unions simultaneously.
Described circular fender bracket is connected successively and formed by many arc carbon fiber rod head and the tail; and the junction of adjacent two carbon fiber rods is positioned at the inside of bilateral adaptor union; the middle part of bilateral adaptor union is formed with a screw simultaneously, and utilizes the method that screw runs through screw that carbon fiber rod end is fixed.
Described connection bracket outermost end at the most on rotor wing unmanned aerial vehicle the distance between rotor fuselage center be greater than the distance between screw propeller outer end to rotor fuselage center.
The agent structure of many rotor wing unmanned aerial vehicles fender guard that the utility model provides adopts carbon fibre material to make, so intensity is high, lightweight, only has grammes per square metre more than 60, and highly versatile.In addition; during due to screw propeller High Rotation Speed all within the protection domain of circular fender bracket; while therefore arriving the obstacles such as wall when aircraft collision; because circular fender bracket has buffer action; therefore can prevent that screw propeller and cyclogyro body are damaged, can significantly reduce aircraft maintenance cost, and aircraft still can continue flight; can protect people around, safety is good simultaneously.In addition, whole fender guard adopts Structured Design, therefore changes the accessory damaging also very easy.
