Embodiment 1

[0028] see figure 1 , a kind of FOD detection radar provided by the present invention, described detection radar comprises: base 1, is a box body, is positioned at airport runway (not shown) on the ground on both sides of the length direction outside and is provided with accommodating groove 100, so The base 1 is installed in the accommodating tank 100, and a connection hole (not shown) is opened in the middle of the upper surface of the base 1; a connecting sleeve 2 is vertically arranged on the upper surface of the base 1 and covered On the outer periphery of the connection hole of the base 1, a rotating shaft (not shown) is arranged in the middle of the inner side of the connecting sleeve 2 along the axial direction of the connecting sleeve 2. The lower end of the rotating shaft is inserted into the connecting hole of the base 1 and extends from the connecting hole. Into the inner side of the base 1; a support platform 3, shaped as a box, erected on the upper opening end of...

Embodiment 2

[0034] The support platform 3 is provided with a detection opening 31 and a cover is provided with a cover (not shown), and the surface of the cover is provided with two antenna openings (not shown) corresponding to the signal receiving antenna 5 and the signal transmitting antenna 6 respectively, A detection opening (not shown) corresponding to one of the supporting openings 42 is defined on the surface of the casing.

[0035] Further, the openings of the two antennas are respectively covered with a transparent cover (not shown).

[0036] Further, the support platform 3 is provided with a detection opening 31 and a number of installation holes 32 are spaced apart at a position close to the edge, and a number of installation through holes corresponding to the installation holes 32 are provided on the side of the cover opposite to the detection opening 31 (not shown), several locking pieces 33 are respectively inserted into the installation through holes and the installation ho...

Embodiment 3

[0040] The support plate 4 surface above the support beam 41 is provided with two support frames 43 at intervals along the length direction of the support plate 4, and the shapes of the two support frames 43 are matched with the shapes of the receiving reflection surface 52 and the emission reflection surface 62 respectively; The receiving reflective surface 52 and the emitting reflective surface 62 are respectively embedded in the support frame 43 .

[0041] The design of the support frame 43 can support and fix the receiving reflective surface 52 and the transmitting reflective surface 62 , so as to ensure the stable operation of the signal receiving antenna 5 and the signal transmitting antenna 6 .

[0042] All the other are with embodiment 1.

Abstract

The invention relates to an FOD (Foreign Object Debris) detection radar which comprises a base, a connecting sleeve, a supporting table, a signal receiving antenna and a signal transmitting antenna, wherein the base is arranged in an accommodating groove; the connecting sleeve is vertically arranged on the upper surface of the base, a rotating shaft is arranged on the inner side, and the lower endof the rotating shaft extends into the inner side of the base through a connecting hole; the supporting table is erected at the opening end of the connecting sleeve, the bottom surface is connected with the upper end of the rotating shaft, a detection opening is formed in one surface facing to an airport runway, a supporting plate is connected with the inside of the detection opening, a supporting beam is convexly arranged on one surface, corresponding to the detection opening, of the supporting plate, and a plurality of supporting openings are formed in the surface of the supporting plate positioned under the supporting beam; the signal receiving antenna is erected at one end of the upper surface of the supporting beam; the signal transmitting antenna is erected at the other end of the upper surface of the supporting beam. The FOD detection radar provided by the invention has the benefits that as the signal receiving antenna and the signal transmitting antenna are placed in a mannerof left and right arrangement in the horizontal direction, the central position of an entire radiation port is lifted, and the interference from the ground is reduced, so that the signal attenuation is weakened, and the full coverage of the runway by the system is maintained.

Description

technical field [0001] The invention belongs to the technical field of airport runway foreign object detection, and in particular relates to a FOD detection radar. Background technique [0002] FOD (Foreign Object Debris), that is, some foreign substance, debris or object that may damage the aircraft. Such as metal parts, waterproof plastic sheets, broken stones, newspapers, bottles, luggage tags, etc., the above are collectively referred to as foreign objects. Typical are: metal parts (nuts, screws, washers, nails, fuses, etc.), mechanical tools, flying objects (personal items, pens, pencils, buttons, etc.), rubber fragments, plastic products, concrete asphalt fragments (stones, sand, ice slag, etc.), paper products, animals and plants, etc. [0003] The harm caused by FOD is very serious. Many cases have proved that foreign objects on the airport pavement can be easily sucked into the engine, causing the engine to fail, and debris will also accumulate in the mechanical d...
