Description
Technical field
The utility model belongs to rail limit sensor technical field, is specifically related to a kind of dust arrester for rail limit sensor.
Background technology
As the core of railway transportation, Train Parts abnormal conditions may be there are in running in train.The safety traffic of this serious threat train.Therefore, to the detection of Train Parts exception, to ensureing that the safe operation of train is most important.At present, gather Train Parts image mainly through the rail limit sensor being arranged on rail limit, then analyze the Train Parts image that collects to realize the detection to Train Parts exception.In above-mentioned testing process, rail limit sensor is owing to being exposed in wild environment, so the eyeglass on casing easily falls to expiring dust.When dust appears in eyeglass, the image that rail limit sensor collects there will be striped, spot etc. and does not know feature.These do not know that feature has a strong impact on the quality of Train Parts image, and then the detection of Train Parts exception cannot normally be implemented.
In order to solve the problem, staff adopts the mode cleaned at regular intervals eyeglass of human at periodic intervals's wiping usually, but, this kind of mode is before the sensor lens care of tracking limit, the Train Parts picture quality that rail limit sensor collects is still lower, and this still affects the detection of Train Parts exception; Wiping easily causes the plated film of eyeglass to occur wearing and tearing frequently simultaneously, affects certainty of measurement.
Utility model content
The purpose of this utility model solves the problem, and provides a kind of anion high-pressure dust-cleaning device for rail limit sensor.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of dust arrester for rail limit sensor, comprise airtight air storage chamber, air storage chamber outlet side is provided with the first anion generator, inlet end is provided with screen pack, inside is provided with the first blower fan, and the outlet side of described air storage chamber is communicated with sensor casing; Also comprise the insufflation channel be communicated with air storage chamber outlet side, described insufflation channel is arranged on the eyeglass on sensor casing for jetting.
Preferably, the port of export of described insufflation channel is provided with the second anion generator, and insufflation channel is provided with the second blower fan.
Preferably, described second blower fan is centrifugal blower.
Preferably, described first blower fan is axial flow blower.
The beneficial effects of the utility model are: the dust arrester for rail limit sensor provided by the utility model; by the dust in the air flow cleaning sensor casing of band anion and on eyeglass; produce the attachment that malleation prevents dust simultaneously; effectively can improve the precision of rail limit sensor; protective lens, has good dedusting and dust-proof effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model for the dust arrester of rail limit sensor.
Description of reference numerals: 1, air storage chamber; 2, the first anion generator; 3, screen pack; 4, the first blower fan; 5, sensor casing; 6, insufflation channel; 7, eyeglass; 8, the second anion generator; 9, the second blower fan.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
As shown in Figure 1, the eyeglass 7 that rail limit sensor comprises sensor casing 5 and is arranged on sensor casing 5, the sensor be arranged in sensor casing 5 gathers Train Parts image through eyeglass 7, dust arrester for rail limit sensor of the present utility model is connected with sensor casing 5, comprise air storage chamber 1 and insufflation channel 6, air storage chamber 1 is containment housing, be provided with outlet side and inlet end, air storage chamber 1 outlet side is provided with the first anion generator 2, inlet end is provided with screen pack 3, inside is provided with the first blower fan 4, outlet side and the sensor casing 5 of air storage chamber 1 pass through pipeline communication, insufflation channel 6 is also communicated with air storage chamber 1 outlet side, and the port of export of insufflation channel 6 is positioned at the below of eyeglass 7, is arranged on the eyeglass 7 on sensor casing 5 for jetting, first blower fan 4 is axial flow blower, in order to ensure the Wind Volume of air storage chamber 1 outlet side, improves dust removing effects.
The operation principle of above-mentioned dust arrester is: start the first blower fan 4, large quantity of air is by entering air storage chamber 1 after screen pack 3 dedusting, first anion generator 2 produces a large amount of anion simultaneously, the pure air being mingled with anion is discharged from outlet side, form the air-flow of band anion, part air-flow enters sensor casing 5, dust in sensor casing 5 is blown away, because the grit in dust is positively charged, the dust be attached in sensor casing 5 is combined with anion, together along with air-flow is blown away, this strand of air-flow also makes to form malleation in sensor casing 5, external dust is made to be difficult to enter, reach good dust-proof effect, another part air-flow enters insufflation channel 6, sprays, blown away by the dust on eyeglass 7 from the port of export of insufflation channel 6, in like manner, due to the existence of malleation, can effectively prevent dust to be attached on eyeglass 7.
In the present embodiment, the port of export of insufflation channel 6 is provided with the second anion generator 8, increase the anion concentration in air-flow, and insufflation channel 6 is provided with the second blower fan 9, second blower fan 9 is centrifugal blower, in order to strengthen the blast of insufflation channel 6 port of export air-flow, improve the dust removing effects to eyeglass 7 further.
The dedusting method of human at periodic intervals's wiping eyeglass is adopted compared to background technology; the dust arrester that the present embodiment provides; by the dust in the air flow cleaning sensor casing of band anion and on eyeglass; produce the attachment that malleation prevents dust simultaneously; effectively can improve the precision of rail limit sensor; protective lens, has good dedusting and dust-proof effect.
Those of ordinary skill in the art will appreciate that, embodiment described here is to help reader understanding's principle of the present utility model, should be understood to that protection domain of the present utility model is not limited to so special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combination of not departing from the utility model essence according to these technology enlightenment disclosed in the utility model, and these distortion and combination are still in protection domain of the present utility model.
