Wherein, impact liquid pool 1, rock sample 2, scroll chuck 3, bracing frame bottom outlet (being used for this device is withstood on ground admittedly) 4, lower grip nut 5, upper grip nut 6, motor speed control device 7, wire 8 motors 9, renovate 10, cover opening handle double-screw bolt 11, cover opening handle 12, bracing frame 13, bracing frame apical pore (being used for fixed motor) 14, motor fixed orifice 15, Upper gasket 16, lower gasket 17, rule 18, mobile chuck bracing frame 19, bubble generator 20.
Embodiment
Referring to Fig. 1, a kind of rock washes away analog machine, it comprises impacts liquid pool 1, impact the liquid pool top and be provided with bracing frame 13, bracing frame is provided with motor 9, and machine shaft is provided with mobile chuck bracing frame 19, be interval with a plurality of scroll chucks 3 on the mobile chuck bracing frame, be provided with rock sample 2 in each scroll chuck, be connected with motor speed control device 7 on the motor, mobile chuck bracing frame side is provided with rule 18.
Described mobile chuck bracing frame middle part is provided with chute, can slide in chute in the scroll chuck upper end, and mobile chuck bracing frame top and bottom correspondence is provided with lower gasket 16,17, and scroll chuck is fixed on the mobile chuck bracing frame by grip nut 5,6 up and down.Described bracing frame top is cavity, and motor is arranged in the cavity, and the cavity top is provided with renovates 10, renovates to have cover opening handle 12.Described bracing frame two ends are provided with bracing frame bottom outlet 4, are used for bracing frame is fixed on the ground.Be provided with bubble generator 20 in the described impact liquid pool.
The above-mentioned purpose of this patent is to realize by such technical scheme: consider the convenience of sampling, mainly use the right cylinder test specimen, the footpath is 50mm-55mm, if the processing instrument is arranged, can dwindle its radius as far as possible, is convenient to the control of rotating speed.Impact the liquid pool the inside and fill impact liquid, impacting liquid can have various ways, comprises that the water that does not contain sand grains, the water that contains emery or on-site sampling have the water of certain sediment charge, can simulate under the multiple aqueous environment current to the souring of rock mass.Impact in the liquid pool that bubble generator being installed, can produce the current of different air bubble contents, make simulated experiment obtain more accurately experimental data.Bracing frame is fixed on a certain plane by the bracing frame bottom outlet, and motor is equipped with in the bracing frame upper end, and motor drives moves the rotation of chuck bracing frame, and further driving clamping has the scroll chuck of rock sample to rotate in unvenile water.In test for avoid rock sample block water face excessive to power require too highly, the following rock sample of triangle pawl dish is immersed in impacts the liquid the inside fully, the rock sample height of submergence is got 2cm.Record the erosive wear value of this section rock sample.By relative motion principle, we make rock sample obtain velocity of rotation in static water.For making rock sample obtain different movement velocitys, arrangements for speed regulation regulation output power that at first can be by motor to be to realize different rock sample velocities of rotation, secondly can realize by the radius of gyration that grip nut is up and down regulated rock sample.Graduated scale on the mobile chuck is convenient to the radius of gyration of fine adjustment rock sample, long 1 meter of graduated scale.And the effect of the upper and lower pad of mobile chuck bracing frame is because the radius of gyration of rock sample will often change, and then also thereupon loosening, clamping of upper and lower grip nut, and in the process of becoming flexible, clamping at upper and lower grip nut, mobile chuck bracing frame is certain to being worn in various degree, so upper and lower pad replaces mobile chuck bracing frame frayed.After upper and lower pad may wear to a certain degree, just change new pad immediately and work on by this equipment.Simulated the process of rock in current scour during this equipment work, we just can come in the laboratory long-term observation to detect the loss situation of rock profile like this, have namely realized our purpose.
This patent is a kind of rock flush equipment, has successfully simulated the profile wear process of rock under current scour.Be in particular in:
1, filled up laboratory simulation and detect the blank that rock washes away loss;
2, but a plurality of rock samples of simultaneously gripping are tested.Namely increase a plurality of movably triangle pawl dishes at horizon bar, can realize once that a plurality of water velocities are to the test of washing away of rock sample.Graduated scale is convenient to the radius of gyration of fine adjustment rock sample;
3, the relation of power of motor and rock sample movement velocity
P=T·w=T·n·2π/60
n=V/(2·π·R)
Therefore P=TV π/30
Wherein, P: electric power (kw), T: moment of torsion (N/m), n: rotating speed (divide/turning), V: velocity of rotation (m/s), R: the rock sample radius of gyration (m) (0＜R＜1m);
4, the maximum eroding velocity of water is about 40m/s in the hydraulic engineering, and motor is less demanding in this patent, and motor common in the daily life can meet the demands;
5, this washout test can be carried out for a long time, also can carry out washing away in short-term;
6, impact the liquid pool the inside and fill impact liquid, impacting liquid can have various ways, comprises that the water that does not contain sand grains, the water that contains emery or on-site sampling have the water of certain sediment charge, can simulate under the multiple aqueous environment current to the souring of rock mass;
7, in the impact liquid pool bubble generator is installed, can be simulated rock mass at the abrasion condition that contains under the water impact of a certain amount of bubble.
