Description
Technical field
The utility model relates to the measurement mechanism of meteorological optical range in meteorological field, particularly a kind of transmission-type atmosphere visibility meter with air curtain structure.
Background technology
Meteorological optical range measurement mechanism is mainly used in the greatest optical sighting distance of the fields such as runway, shipping, Hainan Airlines at that time under meteorological condition, is one of important parameter of meteorologic parameter in these fields.The method of usual employing transmission-type is measured, this measuring method needs a transmitting terminal and a receiving end, the light path launch window of transmitting terminal is corresponding with the light path receive window of receiving end, in order to reduce external environment to the impact of measuring, often will arrange a sky shade at transmitting terminal and receiving end.Find in practice, relatively shady and cool in summer sky shade, mosquito is liked stopping dropping on launch window and receive window, affects measuring accuracy.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of transmission-type atmosphere visibility meter with air curtain structure, utilizes used heat air-flow to carry out mosquito expelling, ensures measuring accuracy.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of transmission-type atmosphere visibility meter with air curtain structure, this atmosphere visibility meter comprises the transmitter and receiver that are oppositely arranged, semiconductor cooling device is provided with in described transmitter and described receiver, this refrigerating plant is connected with radiator fan, described radiator fan is arranged in external air channel, the import in this air channel connects air, outlet lays respectively near the light path launch window of transmitter and the light path receive window of receiver, and air-flow is blown on the lateral surface of described light path launch window and described light path receive window.
Further, the outlet in described air channel is less than the import in air channel.
Further, described radiator fan is positioned at the rear portion of described transmitter and described receiver, and the outlet in described air channel is positioned at the top of described light path launch window and described light path receive window, and is positioned at sky shade.
Transmission-type atmosphere visibility meter with air curtain structure of the present utility model utilizes the radiator fan of semiconductor cooling device as power source, hot blast through radiator fan is delivered to the light path launch window of transmitter and the light path receive window of receiver, gas flow temperature through radiator fan can rise to 40-60 DEG C, utilize this strand of thermal current to disperse and stop dropping on the mosquito on window, effectively make use of originally discarded kinetic energy and heat energy; Ducting outlet reducing can improve blast under the constant prerequisite of air quantity of fan, before making that mosquito is more difficult and stopping dropping on window lens or fly into inside, air channel.
Accompanying drawing explanation
Fig. 1 is the view profile of transmitter in the utility model;
Fig. 2 is the view profile of receiver in the utility model.
Embodiment
Below, with reference to accompanying drawing, the utility model is more fully illustrated, shown in the drawings of exemplary embodiment of the present utility model.But the utility model can be presented as multiple multi-form, and should not be construed as the exemplary embodiment being confined to describe here.But, these embodiments are provided, thus make the utility model comprehensively with complete, and scope of the present utility model is fully conveyed to those of ordinary skill in the art.
For ease of illustrating, here can use such as " on ", the space relative terms such as D score " left side " " right side ", for illustration of the element of shown in figure or the feature relation relative to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as the element being positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and space used here illustrates relatively can correspondingly explain.
Be the specific embodiment of the utility model with the transmission-type atmosphere visibility meter of air curtain structure as depicted in figs. 1 and 2, atmosphere visibility meter comprises the transmitter (with reference to figure 1) and receiver (with reference to figure 2) that are oppositely arranged in the present embodiment.
For transmitter, the technical solution of the utility model is described, semiconductor cooling device 4 is provided with in transmitter, semiconductor cooling device 4 is connected with heating radiator 5, radiator fan 6 is provided with below heating radiator 5, light path launch window 8 is positioned at the front portion of transmitter, radiator fan 6 and heating radiator 5 are positioned at the external air channel 3 at the rear portion of transmitter, the import 7 in air channel 3 connects air, the outlet 2 in air channel 3 is positioned at the top of light path launch window 8, and be positioned at inside sky shade 1, the outlet 2 in air channel 3 is less than the bore of the import 7 in air channel 3, air-flow trend is as direction of arrow instruction in figure, air-flow sucks air channel 3 from the import 7 in air channel 3, after heating radiator 5, temperature rises, 40-60 DEG C can be reached, high temperature gas flow flows out from the outlet 2 in air channel 3 and blows on the lateral surface of light path launch window 8.
Utilize the waste gas hot blast through radiator fan, disperse the mosquito stopping dropping on window; Ducting outlet reducing can improve blast under the constant prerequisite of air quantity of fan, before making that mosquito is more difficult and stopping dropping on window lens or fly into inside, air channel.
Receiver is substantially identical with the technical scheme of transmitter, and difference is, the outlet 2 in air channel 3 is positioned at the top of light path receive window 9, is blown by air-flow on the lateral surface of light path receive window 9.
