Description
Technical field
The utility model relates to soil drifting monitoring technical field, particularly dust storm monitoring device, specifically belongs to a kind of coiled sand-taped instrument.
Background technology
Wind erosion is desertified also known as sandy desertification, is the main type of one of China's desertification, has very large harm to the grain security of China, ecological safety and socio-economic development.Sand-taped instrument is a kind of wind erosion proving installation, requisite instrument when being Mechanism of Wind Blow Sand Movement such as research soil drifting and sand dune movement etc., observation Structure of wind-Sand Flow feature.
Existing sand-taped instrument mostly is square opening, wedge shape or triangle, and the utility model adopts coiled pipe design, mainly make use of the mass conservation of two-phase flow, energy conservation, principle of conservation of momentum, after dust-contained airflow enters dust storm pipe, by the caliber increased, reduces wind speed; And in pipe spoiler effect under, make air-flow produce a large amount of local vortexs, sandy environment collides with each other friction, kinetic energy reduction.Under above-mentioned two factor effects, the grains of sand are due to deadweight generation sedimentation, and some gas overflows from the fabric collection sandbag of good air permeability simultaneously, and fabric collection sandbag also plays the effect of screen filtration.This sand-taped instrument is separated with the efficient of sand and dust by air-flow, thus improves measuring accuracy.
Utility model content
The purpose of this utility model is to provide a kind of coiled sand-taped instrument, and the fixed point utilizing this sand-taped instrument can realize soil sand dust under field environment is collected and accurately measured.
The purpose of this utility model is achieved through the following technical solutions:
A kind of coiled sand-taped instrument, comprises the husky module of collection and stuck-module; The husky module of described collection is made up of snakelike dust storm pipe, collection sand tube, ring plate, collection sandbag, spoiler; Stuck-module is made up of fixed head, the band semi-circular button of nut, auricle and bolt and nut; The steel pipe that snakelike dust storm pipe is increased gradually by diameter forms, between two kinds of diameters, be provided with transition section; In snakelike dust storm pipe, alternative arrangement has spoiler, makes dust-contained airflow produce a large amount of local vortexs; In the bottom of snakelike dust storm pipe, be provided with collection sand tube obliquely in face of carrying out flow path direction; Prevent it from gliding for convenience of fixed set sandbag, the lower end of collection sand tube is welded with ring plate, with band, collection sandbag is fixed in the ring plate of collection sand tube, and sandy environment falls into collection sandbag through collection sand tube; Utilize the semi-circular button of band nut that snakelike dust storm pipe is fixed on fixed head; One end of fixed head is welded with two auricles, by 2 bolt and nuts, fixed head is fixed; In order to not make air-flow form swirling flow in the exit of snakelike dust storm pipe, outlet section upwarps convergent, and exit design becomes the shape of a hoof; For improving measurement result, import and outlet are in the same horizontal line.
As optimization, the quantity of the husky module of described collection is one or more, according to the actual needs measured, and quantification.
Advantage of the present utility model and beneficial effect are:
This sand-taped instrument is according to the mass conservation of two-phase flow, energy conservation, principle of conservation of momentum design, flow velocity and the kinetic energy of gas-solid biphase flow is significantly reduced after dust-contained airflow can be made to enter the husky unit of collection, be convenient to grains of sand sedimentation, air-flow can be reached and be separated with the efficient of sand and dust, thus improve measuring accuracy.
