Abstract
The utility model discloses a wind tunnel measurer for dust and sand soil wind erosion, which consists of a jack, a lifting rack, a transducer bracket, a transducer balancing rack, a pressure transducer, a supporting plate, a dust and sand soil sample box, a wind erosion chamber, a down-lead, a bridge power source and a data acquisition instrument. The lifting rack on the jack is provided with the transducer bracket; the upper end of the transducer bracket is flatly positioned with the transducer balancing rack; the pressure transducer is positioned on the face of the balancing rack; the top of the pressure transducer is provided with the supporting plate which is provided with the dust and sand soil sample box; and the bridge power source is connected with the pressure transducer through the down-lead. The utility model can measure the wind erosion quantity with precise and reliable measuring data through the conversion of the pressure transducer and the coefficient of the data acquisition instrument by utilizing that the weight of the dust and sand soil sample box is lightened when the wind erosion chamber is under the condition of a certain wind speed. The utility model overcomes the error of manual measuring, thereby providing scientific foundation for effectively preventing and curing the dust and sand soil wind erosion.
Description
Technical field
The utility model belongs to a kind of instrument of measuring wind-tunnel sand and dust soil drifting amount.
Background technology
Talk sandstorm, people are familiar.Strong wind has been rolled the dust grains of sand on ground, flies upward sky, shielded from sunlight, causes the scenery dimness, and floating dust is all over the sky, just as fine drizzle, and landing with the wind.Duration reaches 1-2 days, also has the 3-5 of reaching days.
According to investigations: the harm that the atmosphere sand and dust bring industrial and agricultural production, communications and transportation, people's lives is on the rise.Its form of expression is as follows:
1, the sand and dust particle is little, but it is more to contain quartz particles, has very big hardness.When sand and dust sink downwards, immerse open-air locomotive, increase improper wearing and tearing, influence locomotive power, fault also takes place as entering motor interior in sand and dust easily, and sand and dust also have the very big property be infected with, stop up the locomotive lubricating system, or cause grease contamination, the wearing and tearing of aggravation locomotive;
2, sand and dust because of corresponding friction produces static, often have the dust storm electricity to take place in air-flow, make the connection electrostatic high-pressure reach the 700-800 volt, not only communication are disturbed, and destroy instrument and equipment, and bring difficulty to line maintenance;
3, the atmosphere sand and dust make the air muddiness, and visibility reduces, and signal ambiguity is unclear, travels to traffic and brings unsafe factor;
4, sinking of sand and dust to covering the very thin sand and dust of one deck on the plant leaf surface, hindered photosynthesis of plants, influences the growth of plant;
5, sand and dust also have harm to health of human body.The air that contains sand and dust enters respiratory apparatus, and uncomfortable in chest, asthma and cough, respiratory tract are infected, are inflamed, and make respiratory mucosa injured.
In recent years, sandstorm weather frequently occur enjoy various circles of society to pay close attention to.The cause of research sand and dust, motion principle is taked effective prophylactico-therapeutic measures, has been the researcher obligation one can't decline.
Content of the present utility model
Sandstorm weather takes place time and again in China, traces it to its cause: soil drifting is the primary link that development takes place in sandstorm.Wind is the most direct power of soil, airflow properties wherein, the wind speed size, correlated condition of wind action etc. is most important factor in the soil drifting process, a kind of wind-tunnel soil sand and dust wind erosion measuring instrument that provides of the present utility model, its objective is by wind-tunnel chamber simulation test, the accumulator plant coverage rate is under the condition of different wind speed and certain hour, plant reduces between air-flow and the sand and dust transmits, stop soil, sand and dust move and adopt the data that instrument shows the amount of the alleviating aspect of sand and dust soil by pressure transducer and number, for preventing that effectively reducing dust and sand weather provides scientific basis.
The utility model can reach by following measure:
A kind of wind-tunnel sand and dust soil drifting measuring instrument is to be adopted instrument and constituted by horizontal lifting jack, crane, sensor stand, sensor balancing stand, pressure transducer, back up pad, sand and dust pedotheque case, wind-tunnel chamber, lead-in wire, bridge power supply, number.On the crane of lifting jack, be equipped with sensor stand; Its top is provided with the sensor balancing stand, placement force sensor on the sensor balancing stand, and back up pad is arranged at the pressure transducer top, places sand and dust pedotheque case on the back up pad.Adopt instrument at the opposite side number and be positioned on the bridge power supply, lead-in wire is connected bridge power supply with pressure transducer.
The good effect of advantage of the present utility model and generation is:
1, the plant covering face of land is to reduce between air-flow and the sand and dust to transmit, stop soil drifting, one of sand and dust motion effective ways, the utility model adopts wind tunnel simulation experiment, under the air blast condition, alleviating of sand and dust pedotheque case weight, adopt the instrument coefficient conversion by pressure transducer and number, data presented is wind erosion quantity both, and data are accurate, eliminate manual weighing's error, simple and convenient.
2, measurement range enlarges.Whenever did a wind tunnel experiment in the past and all wind-tunnel chamber and sand and dust collecting chamber cleaned up, finish test after, cleaning is collected, and weighs.After adopting the utility model, alleviate the hand labor amount, can obtain the sand and dust soil drifting amount of unit area under different wind speed and different time condition.
3, simple in structure, easy to operate, a whole set of instrument is stable, for the improvement of sand and dust provides reliable science data.
Description of drawings
Structure of the present utility model is illustrated by the following drawings

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail again:
A kind of wind-tunnel sand and dust soil drifting measuring instrument is to be adopted instrument 11 and constituted by horizontal lifting jack 1, crane 2, sensor stand 3, sensor balancing stand 4, pressure transducer 5, back up pad 6, sand and dust pedotheque case 7, wind-tunnel chamber 8, lead-in wire 9, bridge power supply 10, number.On the crane 2 of lifting jack 1, be equipped with sensor stand 3; Its top is provided with sensor balancing stand 4, placement force sensor 5 on sensor balancing stand 4, and back up pad 6 is arranged at pressure transducer 5 tops, places sand and dust pedotheque case 7 on the back up pad 6.Adopt instrument 11 at the opposite side number and be positioned on the bridge power supply 10, lead-in wire 9 is connected bridge power supply 10 with pressure transducer 5.
The lifting jack 1 that hoists, sand and dust pedotheque case 7 enters the opening of 8 bottoms, wind-tunnel chamber, and keeps a plane with 8 bottom surfaces, wind-tunnel chamber, its slit rubber belt sealing.
Under the driving of motor, wind-tunnel chamber 8 fans produce the current rate that increases progressively gradually, when gas velocity reached the numerical value of required observation, under the effect of intensity air-flow, sand and dust soil began to move, and the motion speed up, fill the air whole wind cavern 8 and collecting chamber, 7 weight savings of sand and dust pedotheque case adopt on the instrument 11 reading number to come from number, this numeral is reflected under certain gas velocity, the wind erosion quantity of unit area in the certain hour.
Utilize similar test can measure different area under different wind speed, different time condition, the wind erosion quantity of sand and dust soil.
