Abstract
The utility model relates to a sand trap instrument which is composed of a conical cover and a glass test tube which are sleeved; the conical surface of the conical cover is provided with a terrace-shaped sand inlet and a square air outlet; moreover, a 45-degree angle between the square air outlet and the taper axial line. The glass test tube is cone-shaped, and the right and the left pipe wall are provided with scale. A sand network is provided at the interface of the cone-shaped inner wall and the sand inlet and the air outlet. The utility model can solve the problem of collecting sediment flux data from a plurality of points on the site under sand flow severe condition, which can provide theory basis to research sand physical law, regulate soil and govern sandstorm.
Description
The utility model provides a kind of instrument that is used for the husky flux of acoustic wind sand drift.
In recent years, spread wantonly, the frequent sandstorm that takes place is with the direct life that influences the national economic development and the people.Better people's living environment in the regulation territory.Reproduce a home with beautiful landscape and caused the great attention of governments at all levels.The radical cure sandstorm is a complexity, polynary coenocorrelation chain.Except strengthening making laws, improve people and protect environmental consciousness, reduce and pollute, outside progressively improving the ecological environment, also must study the cause of sandstorm, the characteristics of motion provides the theoretical foundation of administering sandstorm from scientific experimentation.Rule between research wind direction, wind speed and drift sand, husky flux is a very important physical quantity.In the stream scene, the husky flux data of collection of multiple spot, must utilize the architectural feature and the stream motion feature of this instrument by a kind of instrument, just can obtain the size of husky flux in unit area, unit interval.
The utility model provides a kind of sand-taped instrument just from this purpose.In the scene of stream, under the effect of certain wind speed, the grains of sand that flow are by the sand inlet of this instrument in the open air, and air-flow is discharged from exhausr port, make grains of sand sedimentation to flow in the glass test tube naturally.Grains of sand horizontal scale amount from test tube so just can calculate the size of husky flux.
The purpose of this utility model can realize by following measure:
A kind of sand-taped instrument is made up of taper shape cover and glass test tube socket, and the conical surface of conical cover is provided with the sand inlet and the rectangle exhausr port of terrace with edge shape, and the rectangle exhausr port becomes 30-45 ° of angle with the circular cone axis.Glass test tube is taper, and scale is arranged about tube wall.At conical inboard wall and exhausr port husky net is arranged at the interface.
The good effect of advantage of the present utility model and generation is:
1, simple in structure, easy to operate, practical, cost is low.In the stream scene, the grains of sand concentrate on overhead 20 centimetres of high scopes in a large number, according to the drift sand motion characteristics, allow husky mouthful over against wind direction, and multiple spot is settled sand-taped instrument, and repetition test just can be understood the stream characteristics of motion of certain limit.
2, reasonable in design.The husky chamber of exhausr port and test tube build-up pressure balance, air-flow is discharged from exhausr port, thereby reduces the husky chamber of test tube upper punch gas velocity.Under the obstruct of sand net, the drift sand natural subsidence is piled up, thereby reduce the error of husky flux.

The conical cover of Fig. 2 A-A cut-away view
Below in conjunction with accompanying drawing, be described in further detail again with regard to the utility model:
A kind of sand-taped instrument, the master is made up of taper shape cover 1 and glass test tube 2 sockets, and the conical surface of conical cover 1 is provided with the sand inlet 3 and the rectangle exhausr port 4 of terrace with edge shape, and rectangle exhausr port 4 becomes 30-45 ° of angle with the circular cone axis.Glass test tube 2 is taper.Scale is arranged about tube wall.At conical inboard wall and exhausr port 4 the husky net 5 of 300 purposes is arranged at the interface.
In the stream scene, sand inlet 3 is over against wind direction, under wind action, the grains of sand of amount enter sand inlet 3, because exhausr port 4 and the husky chamber of test tube build-up pressure balance, air-flow is discharged from exhausr port 4, thereby reduces the husky chamber of test tube upper punch gas velocity, under the obstruct of husky net 5, the drift sand natural subsidence is deposited in the test tube 2, unloads circular cone cover 1, the grains of sand horizontal scale amount in the test tube 2, just can calculate in the unit interval data of the long-pending husky flux of single face.
Claims (3)
1, a kind of sand-taped instrument, form by taper shape cover (1) and glass test tube (2) socket, it is characterized in that: the conical surface of conical cover (1) is provided with the sand inlet (3) and the rectangle exhausr port (4) of terrace with edge shape, glass test tube (2) is taper, scale is arranged about tube wall, conical inboard wall with and exhausr port (4) husky net (5) is arranged at the interface.
2,, it is characterized in that exhausr port (4) becomes 30-45 ° of angle with the circular cone axis according to the described sand-taped instrument of claim 1.
