Abstract
The present invention relates to a reversible multi-metering settlement barrel which is mainly used for the particle experiment fields of water utilization project, etc. The settlement barrel comprises the following components: a square barrel, a sealing ring, a sealing cover with an opening, an overturning collet and a plurality of fixed bolts. The settlement barrel is used for placing the particulate matter and fluid medium and fluid medium to be measured. The sealing device is designed with a flange form. Firstly the sealing ring is placed and then the sealing cover is placed. The sealing device is fixed by bolts. The opening on the sealing cover has two purposes of fluid injection and ventilation. The sealing cover can be placed on the concave collet when the barrel is overturned for using. The reversible multi-metering settlement barrel can execute a plurality of repeated metering to the same measuring object, prevents the error caused by the outer interference to the measuring result and increases the measuring precision. The design of square barrel causes that the settlement barrel not only can execute traditional test measurement, but also can use a camera device for recording the process of particle settling movement. Simultaneously the using of the reversible multi-metering settlement barrel is more flexible. The repeated closed experiments or unclosed open experiments can be selected according to requirements.
Description
Technical field
The present invention relates to a kind of settlement barrel of novel measurement subsiding movement, belong to the hydraulic engineering technical field.
Background technology
The particles settling motion measurement is a substance of hydraulic engineering scientific research and test, is used for measuring particle sinking speed and measures grain composition etc.Traditional settlement barrel is generally the right cylinder of upper end open, thickness or parameters such as density or penetrability by the observation particle deposition are come the heavy speed of indirect count particles, owing to the image processing and analyzing development of technology, the research of using image analysis technology to measure movement of particles also gets more and more in recent years.Measure in order to make the particles settling motion carry out repeated multiple times, so design the square settlement barrel of a reversible multi-metering in conjunction with camera technique.Can obtain the sequence image of particles settling intuitively on the one hand, can also directly obtain the true velocity of particles settling in addition, obtain the more data of microscale by graphical analysis.
Summary of the invention
For realizing combining of settlement measurement and picture charge pattern technology, change original single of measuring, realize the nothing distortion of sedimented particle is made a video recording and to the purpose that same measuring object carries out repeatedly repeated measurement, provided a kind of sedimentation square tube of reversible multi-metering.It mainly comprises square cylinder, packoff and collet three parts.
The settlement barrel of a kind of reversible multi-metering that the present invention proposes is characterized in that, described settlement barrel is by open core structure, and packoff and collet are formed; The square tube formula structure of described opening is made up of gland bonnet (3), concave shape collet (4) and the bolt (6) of square cylinder (1), O-ring seal (2), (5) with holes; Described O-ring seal (2) eyelet is placed on the square cylinder (1) one to one, and gland bonnet (3) is placed on the O-ring seal (2), by bolt (6) square cylinder (1), O-ring seal (2) and gland bonnet (3) three is fixed together; When inversion state, settlement barrel is positioned in the concave shape collet (4).
In above-mentioned settlement barrel, described concave shape collet (4) removes one piece with a cube in a side according to the cylindrical shell size, has the hole (5) of stretching out on the gland bonnet (3) and is embedded in together so that make, and makes settlement barrel keep balance when being inverted.
Put into particle to be measured when device provided by the invention uses in tube, sealing makes water-tight, and measurement multi-group data repeatedly can overturn.Compared with former device, this device has following characteristics:
1. adopt transparent material to make, light transmission is good, and light can freely see through, and is beneficial to dozen sheet or band light source and takes;
2. cylindrical shell is provided with packoff, mainly is made up of O-ring seal and gland bonnet, uses form of flanges to carry out fixing seal;
3. a dual-purpose hole of ventilative water filling is set on the gland bonnet, guarantees that on the one hand inside and outside air pressure balance on the other hand can water filling fully extrudes gas and guarantee do not have bubble in the seal;
4. settlement barrel adopts the rectangular cross section design, combining with picture pick-up device when using, obtains the image that does not have distortion in the time of can guaranteeing to make a video recording, and improves because the problem of deformation of image when using circular settlement barrel;
5. different with former cylindrical open settlement barrel, this product can be overturn repeatedly and be measured, and with tongs bleeder vent is sealed get final product when upset is used, and improves the efficient and the accuracy of acquisition test figure;
6. product is simple in structure, and cost is lower, and material obtains easily, is beneficial to the laboratory and uses;
7. can not only be used for traditional settlement measurement, and be applicable to measurement in conjunction with the photography tracer technique;
8. this device also can be taken use apart, as the open measurement data of carrying out of need, then can not use packoff directly to use, and is convenient, flexible.

Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
The 1-square cylinder
The 2-O-ring seal
The 3-gland bonnet
4-concave shape collet
The 5-hole
The 6-bolt
The 7-settlement barrel
The 8-light source
The 9-video camera
10-image acquisition main frame
Described O-ring seal (2) eyelet is placed on the square cylinder (1) one to one, gland bonnet (3) is placed on the O-ring seal (2), by bolt (6) square tube (1), O-ring seal (2) and capping (3) three are fixed together, when inversion state, settlement barrel (1,2,3 connectors) is placed on concave shape collet (4).
Can be as follows during enforcement: put into fluid media (medium) and particle to be measured when this device is brought into use in cylindrical shell (1), can carry out one-shot measurement this moment; When needing sealing to use, place O-ring seal (2), gland bonnet (3) successively, make water-tight with bolt (6) sealing, if there is this moment gas to exist in the tube, then inject exhaust liquid by hole (5), use the tongs sealing, the upset cylindrical shell, the hole (5) on the gland bonnet was placed on the collet (4) facing to the position that falls in of concave shape collet and carried out another time measurement this moment; After this just can just put to be inverted and replace the subsiding movement of observing and measuring particle.
