The invention discloses a radar lever meter horn antenna with a cleaning device, belonging to the technical field of level measurement. The radar lever meter horn antenna comprises an antenna main body and an antenna cover fixedly connected with a wide port of the antenna main body. The radar lever meter horn antenna is characterized by further comprising a motor, a transmission mechanism and a scraper; the motor drives the transmission mechanism; and the transmission mechanism drives the scraper to scrape attachments on the surface along the surface of the antenna cover. The radar lever meter horn antenna can be used for industrial level measurement.
Description
Technical field
The present invention relates to radar levelmeter, relate in particular to the horn antenna for radar levelmeter, belong to the level gauging technical field.
Background technology
Radar levelmeter is widely used in the modern industry level gauging as a kind of non-contact measurement.Principle is that electromagnetic wave is launched via antenna element, arrives the measured object surface, and is received by antenna again in the reflection of measured object surface.Just can calculate the electromagnetic wave transmitting site to the distance between the measured object surface by transmitting and receiving the electromagnetic time difference.Antenna element plays crucial effect as the part that transmits and receives of electromagnetic wave signal in measuring process.Horn-like antenna exists various ways to satisfy the different measuring environment requirement as one type of antenna.
Radar levelmeter is in measuring thing position process, and measurement environment can affect to radar antenna.Some measured medium has the characteristic of volatilization, distillation or strong dust.In the time of in coagulation, crystal or dust are attached to common horn antenna, hindered electromagnetic transmission path, made to measure to be affected.And by installing easy radome additional, can suitably alleviate the problem that is blocked in the influence measurement that causes in the antenna by volatile matter or dust.But when attachment increased, the attachment on radome equally also can bring influence to measurement.
Summary of the invention
The objective of the invention is to overcome problems of the prior art, propose a kind of radar levelmeter horn antenna with clearing apparatus.The radar levelmeter horn antenna that the present invention proposes has carried out perfect to original antenna structure, by the mode of initiatively cleaning, removal covers the coagulation on radome, guarantees that the electromagnetic wave signal delivering path is unblocked, and the operating mode that commute crystallization dewfall and dust are big has extremely strong adaptability.
Horn antenna of the present invention improves on the basis of original antenna structure, enables to adapt to various easy crystallization dewfall and the big operating mode of dust.
Specifically, radar levelmeter horn antenna of the present invention comprises antenna body, radome, motor, transmission mechanism and the scraper of fixedlying connected with the wide mouth of antenna body.The described transmission mechanism of described driven by motor, described transmission mechanism drives described scraper and strikes off lip-deep attachment along the surface of described conical antenna cover.
It is horn-like that antenna body preferably is, and preferably made by metal material, to play electromagnetic signals and the effect of accepting electromagnetic wave signal.
Radome preferably is turbination, stops dust, volatilization crystal to enter in the cavity of bell-mouth antenna main body on the one hand, and avoiding clogging influences the transmission of electromagnetic wave signal; The shape of radome self, thickness, material are (generally by the PTFE(polytetrafluoroethylene on the other hand, Polytetrafluoroethene), PP(polypropylene, Polypropylene), PE(polyethylene, Polyethylene), the copolymer of F46(tetrafluoroethene and hexafluoropropylene), fluorine advanced low-k materials such as (Kynoar) is made partially) can not cause boundary reflection to the electromagnetic wave signal that penetrates, prevent from forming extra interference echo.
In a preferred examples, described horn antenna also comprises flange, and flange is installed the part existence that is connected as structural member and process in whole device, and then radome is fixedlyed connected by the wide mouth of flange and antenna body; Motor then can be fixedly set on the flange, as the power source of whole device, and for the rotation of scraper provides power, and can be according to what degree of attachment, the control motor rotates, and makes cleaning more efficient.
In a preferred examples, described transmission mechanism comprises pinion, gear wheel, rotating disk, bearing and doctor blade holder; The rotating shaft of pinion and motor is fixedlyed connected, gear wheel and pinion, and rotating disk is fixedlyed connected with gear wheel, and rotating disk is connected with radome by bearing and around the radome motion, scraper is then fixedlyed connected with rotating disk by doctor blade holder.Thus, under the drive of motor, scraper strikes off lip-deep attachment by the transmission of transmission mechanism along the surface of radome, such as in dust, crystal and the coagulation one or more.
In addition, on the doctor blade holder stage clip and the decorative pearl on top of an official cap can be set, they make the knife edge of scraper be close to the surface of radome, thereby improve the efficient of striking off of scraper, make cleaning works more thorough.
Compare with prior art, advantage of the present invention is embodied in:
When existing horn antenna used under the condition of volatile crystallization or dust, coagulation or dust can get lodged in the horn antenna, thereby made the pulse electromagnetic transmission be hindered the instrument cisco unity malfunction.In the present invention, when coagulation or dust accumulation are on radome, can clear up the radome surface by the driven by motor scraper, the radome surface is kept clean, guarantee the unimpeded of electromagnetic transmission approach.Thereby radar levelmeter can be adapted under the environment of crystallization or strong dust that easily condenses works.
