Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.
Referring to fig. 1 or 2, the present invention provides a device for real-time measurement of rock water absorption rate, which comprises a supporting table 1, an electronic scale 2, a sample container 3, a hoisting member 4, a column 5, a water storage tank 6 and a computer 7. Electronic scale 2 is placed to supporting table 1 upper surface level, aqua storage tank 6 for upper end open-ended cylindrical transparent container, place in the area of weighing of electronic scale 2, electronic scale 2 links to each other with computer 7 through the signal line, electronic scale 2 and computer 7 all connect the power, 5 lower parts of stand be flexible straight-bar, upper portion is "7" font pole, 5 one end of stand connect fixed mounting on supporting table 1 through detachable, the other end of stand 5 be connected with hoist and mount piece 4, hoist and mount piece 4 for the pole that hard material preparation that does not absorb water formed, hoist and mount piece 4's lower extreme hangs dress appearance container 3, dress appearance container 3 weave by the iron wire and form cylindrical permeable container, dress appearance container 3 top is equipped with open closed lid, the lid weave by thin iron wire and form.
Utilize the utility model provides a when device of real-time measurement rock water absorption rate is tested, concrete step is as follows:
and step S1, placing the supporting platform 1 and the electronic scale 2 to form a three-foot cantilever weight measuring platform. Placing the natural rock sample on an electronic scale 2 to obtain the weight m of the rock sample0And recording the data.
And step S2, taking down the rock sample and lifting the upright post 5. The cover of the sample container 3 is opened, the rock sample is placed in the sample container 3, and then the sample container 3 is connected and hung on the upright post 5 through the hanging rod piece 4.
Step S3, injecting purified water into the water storage tank 6, placing the water storage tank 6 on the electronic scale 2, and measuring the initial weight m of the water and the water storage tank 60', data is recorded.
And step S4, descending the upright post 5 until the rock sample is immersed in the water to a certain depth, and fixing the position of the upright post 5. When the height of the upright post 5 is reduced, the operation is rapidly carried out on the premise of keeping the water surface not to generate violent shaking; the depth of immersion should be such that the sample container 3 containing the rock sample is completely immersed in the water without the sample container 3 contacting the bottom of the reservoir 6.
Step S5, after the liquid level is calm, the data m of the electronic scale 2 is read quickly1'. According to the principle of fluid mechanics when water is presentAt rest, its interaction with the submerged object is a buoyancy in the vertical direction, and therefore, (m)1’-m0') g is the buoyancy of the sample container 3 and the rock sample. Since the hoisting piece connecting the sample container 3 and the upright post 5 is a non-water-absorbing rod, the buoyancy does not change greatly along with the water absorption of the rock, so that the value can be approximately considered as (m)1’- m0') g is a constant value.
Step S6, a film is coated on the top of the transparent water storage tank 6 to prevent errors caused by water evaporation, and then the electronic scale 2 is quickly connected with the computer 7 to enable the computer 7 to obtain the measured value m' of the electronic scale 2 in real time.
In step S7, the computer 7 can convert the measured value of the electronic scale 2 into the water absorption of the rock sample according to the following formula, and the data sampled by the computer 7 is imported into a mapping tool, so as to obtain a continuous "water absorption-time" curve.
ω＝{m0’-[m’-(m1’-m0’)]}/m0×100％
＝(m1’-m’)/m0×100％
In the formula, omega is water absorption, and m' is a real-time measured value of the electronic scale 2; m is1' is the measurement value of the electronic scale at the moment when the sample container 3 and the rock sample are completely immersed in water; m is0Is the natural weight of the rock.
And step S8, when the change of omega is very small, namely the interval is 6 hours, the change value delta omega of omega is less than or equal to 0.01 percent, and the rock can be considered to be saturated by water. And after the test is finished, storing the data and arranging the device.
Of course, the above is only the preferred embodiment of the present invention, and the application range of the present invention is not limited thereto, so all the equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
