Abstract
The utility model provides a plastic horn antenna, which belongs to the technical field of impulse radar material level meters. The plastic horn antenna comprises an oscillator, a plastic horn, a dust cover and a collar clamp, wherein, the inner wall of the plastic horn is covered with a metal layer, and the dust cover is fixed on the plastic horn through the collar clamp. The utility model has the advantages that the measurement effect is ensured, and the process is simpler and the cost is lower at the same time.
Description
Technical field
The utility model is the design about the pulse radar level meter, is specifically related to a kind of pulse radar antenna.
Background technology
During the modern industry level gauging was used, the pulse radar level meter was widely used in level gauging as a kind of contactless radar levelmeter.Principle is that pulse electromagnetic wave is launched via antenna assembly, arrives the measured object surface, and is received by antenna assembly in the measured object surface reflection.Just can calculate instrument to the distance between the measured object surface by transmitting and receiving the electromagnetic time difference.Its antenna assembly plays important effect as the electromagnetic part that transmits and receives in measuring process.Antenna structure can influence the power that transmits and receives signal, and whether the decision instrumentation is normal.At present, existing metal horn antenna cost is higher, processed complex, and anti fouling performance is poor.
The utility model content
The utility model has overcome deficiency of the prior art, and a kind of plastics horn antenna of alternative metals horn antenna is provided.
The technical solution of the utility model is:
A kind of plastics horn antenna is characterized in that, comprises oscillator, plastics loudspeaker, dust cover and clip, and plastics loudspeaker inwall adheres to a metal level, and dust cover is fixed on the plastics loudspeaker by clip.
Compared with prior art, advantage of the present utility model:
The form of the utility model plastics loudspeaker additional metal layer has reduced cost again when satisfying electromagnetic wave to transmit and receive function.Compare with existing metal horn antenna, when guaranteeing measurement effect, the simpler cost of technology is lower.
Description of drawings
Fig. 1 is a plastics horn antenna profile.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
With reference to figure 1, the utility model comprises oscillator 1, plastics loudspeaker 2, the coat of metal 3, dust cover 4 and clip 5.Plastics loudspeaker 2 are appearance structure spare, and wall adheres to the last layer coat of metal 3 within it.4 of dust covers are fixed on the plastics loudspeaker 2 by clip 5.
Oscillator 1 material of the present utility model is PTFE or PP or F46, and electromagnetic wave sends thus and receives; Dust cover 4 materials are PTFE, PP, PE, F46, inclined to one side fluorine, play and avoid oscillator to pollute the influence that electromagnetic transmission is brought decay; Clip 5 materials strengthen PP (or plastics), and dust cover is fixedlyed connected with horn-like antenna.
Loudspeaker 2 materials are enclosed metal level 3 (or metal film) for strengthening PP or plastics in the plastics loudspeaker 2, common formation transmits and receives the antenna horn of electromagnetic wave signal, can satisfy the electromagnetic effect that transmits and receives, and can reduce cost again.
The metal level that adheres in the utility model plastics horn structure spare comprises that plating, brush metallic paint, subsides metal film etc. add the form of adhesion metal layers.
More than by specific embodiment plastics horn antenna provided by the utility model has been described, it will be understood by those of skill in the art that in the scope that does not break away from the utility model essence, can make certain deformation or modification to the utility model; Its preparation method also is not limited to disclosed content among the embodiment.
