Abstract
The invention discloses a protective device for propellers of an unmanned aircraft. The protective device consists of an aluminum substrate, a plurality of fixing screws and a propeller protecting hood. The protective device is characterized in that an edge rib is prefabricated on the outer edge of the aluminum substrate; a protection-hood inserting groove matched with the edge of the propeller protecting hood is formed in one side of the edge rib, and the edge part of the propeller protecting hood is fixed through the penetration of the fixing screws; an oblique conical surface is prefabricated on the outer edge of the protection-hood inserting groove; a plurality of round holes are formed in the plate body of the aluminum substrate; propeller reserving openings are respectively formed in both sides of the propeller protecting hood. The edge rib is prefabricated on the outer edge of the aluminum substrate, the protection-hood inserting groove matched with the edge of the propeller protecting hood is formed in one side of the edge rib, and the edge part of the propeller protecting hood is fixed through the penetration of the fixing screws, so that the protective device is convenient to mount and dismount, and is safe and firm. The oblique conical surface is prefabricated on the outer edge of the protection-hood inserting groove, so that the weight of parts can be reduced, the manufacturing materials can be saved, and the air resistance can be furthest reduced.
Description
Technical field
The present invention relates to a kind of Propeller Guard field, particularly relate to a kind of unmanned plane Propeller Guard device, for the protection of unmanned plane screw propeller.
Background technology
Chinese Patent Application No. 2013106701000 discloses a kind of blade clamping structure, annular arrangement binding cylindrical has step A and step B; Wheel hub inwall has the clamping boss with the clamping of annular arrangement binding phase, the step A of annular arrangement binding coordinates with the blades installation hole on wheel hub, is connected on the clamping boss on wheel hub inwall; Blade flange dish end there is the knock hole matched with the step B of annular arrangement binding, the position that annular arrangement binding is corresponding with blade flange dish has tapped bore, with bolt and spring washer circle blade flange dish and annular arrangement binding is adopted and be fixed together.The present invention transport, easy to carry, can carry out the measurement of blades installation angle whenever and wherever possible, accuracy in detection is high, and work efficiency is high; Measurement cost is low, reduces storage space.Adopt by blades installation on wheel hub, the setting angle of blade is adjustable in the scope of 0 °-90 °, and setting range is large, installation, convenient disassembly, and positioning precision is high.
Chinese Patent Application No. 2015100517934 discloses a kind of autogyro screw propeller location damping brake gear, under this device is mainly used in autogyro air accident situation, make screw propeller location, damping, brake, when avoiding launching double-purpose umbrella, ejection bailout, propeller blade blocks launch window; A kind of annular housing inwall installs one or more one-way positioning device, slide block, annular damping cylinder or annular damping oil cylinder, reset damping spring are installed inside cavity, curved bar by annular damping cylinder or annular damping oil cylinder piston chain, slide block by curved bar chain, reset damping spring is enclosed within annular damping cylinder or oil cylinder, and one end heads on bottom cylinder or oil cylinder, and the other end heads on slide block, slide block is installed movable arm unit, movable arm unit and prop shaft install stop member.Movable arm unit has electrical control unit control action, stops that propeller blade or prop shaft rotate, and produce damping, locating effect time anxious.
Summary of the invention
The object of this invention is to provide a kind of unmanned plane Propeller Guard device, which overcome the shortcoming of conventional gasoline mode, very convenient carrying is moved and is used.
For achieving the above object, present invention employs such technical scheme: described unmanned plane Propeller Guard device, is made up of aluminium base, check screw, screw propeller guard shield; It is characterized in that, the outer of aluminium base is prefabricated with along muscle, and the side along muscle is provided with the guard shield caulking groove along portion's joint match with screw propeller guard shield, and by several check screws run through fixing screw propeller guard shield along portion; The outer of guard shield caulking groove is prefabricated with scalene cone; Several circular holes are provided with in the plate body of aluminium base; The structure both sides of screw propeller guard shield are prefabricated with screw propeller reserved opening.
After adopting such structure, the outer of aluminium base is prefabricated with along muscle, and the side along muscle is provided with the guard shield caulking groove along portion's joint match with screw propeller guard shield, and by several check screws run through fixing screw propeller guard shield along portion; Like this, both to install, convenient disassembly, again securely.The scalene cone that the outer of guard shield caulking groove is prefabricated, can alleviate the weight of parts, save manufactured materials, and reduce air resistance to greatest extent.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of concrete structure of the present invention; Fig. 2 is the partial enlarged drawing shown in Fig. 1.
Detailed description of the invention
