Technical Field

The invention relates to the technical field of field snow protection and removal, in particular to an automatic and interference-free small-range snow protection and removal device.

Background

With the development of automatic observation technology, more and more instruments are placed in the field to acquire various types of data continuously for a long time, however, the optical or infrared sensors of many instruments are often affected by snowfall and covered by snow in winter. During snow cover, the observation is forced to be interrupted, which affects the continuous observation, and even long-term snow cover can cause irreversible damage to the sensors of the instrument.

In order to solve this problem, many protective measures have been proposed, such as manual wiping, heat melting, wind blowing, scraping, and the like. Each of these methods has advantages and disadvantages, which we analyze here:

the manual wiping method requires that a professional maintainer quickly reaches the vicinity of the instrument after the snowfall stops to clear away the snow on the sensor of the instrument. The method has the advantages that the accumulated snow can be rapidly cleared in a short time, the running condition of the instrument can be observed when the accumulated snow is erased, and the device can be overhauled in time if a problem is found. The drawback is also evident in that in winter, areas are difficult to reach due to the effect of snow, while the manual maintenance of some instruments, which may be erected above a high tower, is time-consuming and labour-intensive in winter, with the attendant risks.

The heat melting method has an advantage in that the treatment can be performed without contacting the instrument. However, in winter, the method consumes more energy, and when the amount of covered snow is large, long-time heating is needed, heat generated by heating may interfere with infrared probes of some instruments, and long-time heating may cause data measured by the instruments to deviate.

Wind blowing methods can be roughly divided into two types, one is that natural wind is gathered to blow, and snow on the surface of an instrument is blown away; the second type is to blow off the accumulated snow on the surface of the instrument by using a motor to drive a fan. Both methods can try to blow away the accumulated snow without contacting the instrument. Meanwhile, the snow blowing by natural wind does not need to consume too much energy, and can be normally operated at a lower temperature, but the main defect of the snow blowing device is that the natural wind is unstable, the snow can not be blown off in time when the snow falls every time, and once the accumulated snow covers the surface of the snow blowing device for a long time, the blowing difficulty can be rapidly increased. The method of blowing snow by using the fan can ensure stable snow blowing frequency, but the fan needs to be close to the instrument in the snow blowing process, which may interfere with the normal operation of the instrument at other times.

The scraping method mainly uses a tool like a windscreen wiper to scrape the snowfall on the surface of the instrument. The method can automatically scrape snow on the surface of the instrument; but is more suitable for planar instruments, which need to be modified when the surface of the instrument to be protected is not planar, with the risk of damaging the instrument.

Therefore, how to provide an automatic and nondestructive protection device for realizing snowfall protection of field instruments is a technical problem which needs to be solved by technical personnel in the field urgently.

The protective cover 3 is connected with the telescopic rod 2; specifically, the protective cover 3 is formed by splicing two rectangular plastic plates, and the opening angle formed by the two plastic plates is 120 degrees. The heating assembly is heating carbon fiber which is positioned at the inner sides of the two rectangular plastic plates.

The snow sensing mechanism 4 is used for acquiring a snow signal; the snowfall sensing mechanism 4 mainly comprises two parts, namely a sensing probe and a signal output line. The surface resistance of the snowfall sensing probe rapidly changes greatly in a snowfall state, so that the current passing through the surface of the snowfall sensing probe rapidly increases, the snowfall phenomenon can be detected sensitively, and the snowfall starting and stopping time is given through the signal transmitter. The snow sensor mechanism may employ a commercially available snow sensor, for example, a rain and snow sensor of model RY-YX.

The controller 5 is respectively connected with the telescopic driving assembly 2 and the snowing sensing mechanism 5 in a communication way; the controller 5 is used for outputting an extending or retracting driving instruction to the telescopic driving component 2 according to the snowfall signal, and the telescopic driving component 2 is used for driving the telescopic rod 1 to extend or retract according to the extending or retracting driving instruction, so that the telescopic rod 1 drives the protective cover 3 to move above equipment to be protected or return to a standby position.

Furthermore, because in the field environment, the condition that the condition such as dust and rainfall probably appear and cause snowfall response mechanism to appear the condition of misjudgement, in order to guarantee the device that this application provided to the accuracy of snowfall judgement. The embodiment of the application can also provide that the snowing sensing mechanism 4 comprises a sensing probe and a signal output line, a heating component is arranged in the sensing probe and used for melting snow on the surface of the sensing probe, the controller comprises a control chip 6, the control chip is connected with a snowing signal receiver 7 and a temperature sensor 8, the snowing signal receiver 7 is connected with the output line, and the control chip 6 is connected with the telescopic rod driving component 2; the control chip 6 performs the following operations:

judging the temperature value obtained by the temperature sensor while receiving the snowfall signal; judging whether the temperature value is in the snowing temperature interval or not; the snowfall temperature interval can be determined according to the local temperature interval of snowfall in the past year provided by the local meteorological office of the device installation area. Usually, the snowfall occurs when the temperature is below-2 ℃, if the temperature acquired by the temperature sensor is higher than-2 ℃, the probability of the snowfall is very low, therefore, the snowfall sensing mechanism does not need to be started, when the temperature is lower than-2 ℃, the power supply of the snowfall sensing mechanism is switched on, the snowfall sensing mechanism detects the snowfall situation in real time, and when the current value transmitted to the control chip by the snowfall sensing mechanism changes suddenly, the snowfall situation is determined, and the equipment to be protected needs to be protected. The method can accurately judge the snowfall, and can effectively save electric energy. Energy waste caused by continuous work of the snowfall induction mechanism is avoided. Of course, the temperature threshold for determining snowfall should be adjusted in time according to the different positions of the instruments.

And if so, outputting the extension driving command to the telescopic driving component.

The control chip 6 is further configured to perform the following operations:

and if the snowfall signal is determined to stop, delaying for 30 minutes and outputting a retraction driving instruction to the telescopic driving assembly.

When the temperature and the snowfall signal do not meet the preset conditions, the telescopic rod is in a contraction state; when the temperature and the snowfall signal are detected and meet the preset conditions, the telescopic rod extends; when the snowfall signal stops, the telescopic rod is retracted after 30 minutes; when the temperature signal is not satisfied, the telescopic rod continues to keep the extension state until the telescopic rod is contracted after delaying for 30 minutes after the snowfall signal stops.

Because the protective cover cannot completely wrap the equipment to be protected, partial snow possibly falls onto the equipment to be protected at a gap, and in order to remove the partial snow in time, the inner side of the protective cover can be provided with a heating component 9, and the heating component 9 is connected with the controller 5; the control chip 6 is further configured to perform the following operations:

and when the snowfall signal is determined to stop, outputting a heating control instruction to the heating assembly so that the heating assembly can be heated after receiving the heating control instruction. The judgment of the snowfall signal stop can be that the snowfall is determined to stop after the surface current of the induction probe is reduced, and the heating assembly can melt the snow on the equipment to be protected after heating, so that the purpose of removing the snow is achieved. The protective cover is connected with the telescopic rod and consists of two rectangular plastic plates, and the inner surface of the protective cover is attached with heating carbon fibers. The size of the plastic plate can be 25cm by 15cm, and the opening angle of the two plates is 120 degrees; the heating carbon fiber on the inner surface starts to heat when the telescopic rod receives the retraction signal and delays retraction, and stops after 30 minutes.
