Abstract
The invention relates to a weathering classification apparatus for determining the degree of surface weathering of rock material located in the field under atmospheric effects.
Description
Technical Field
The invention relates to a weathering classification apparatus for determining the degree of surface weathering of rock material located in the field under atmospheric effects.
Background
There is a great deal of research in the prior art to determine surface efflorescence of rock materials under atmospheric effects. To determine the extent of in-field rock efflorescence, researchers have developed various methods. In these methods, the rock material has been examined for weathering effects, color changes, artificial damage, decomposition in water containers and changes in the texture of the rock. In a rock weathering classification system, the degree of weathering ranges from 1 to 6, while rocks with a degree of weathering of 1 represent undamaged rocks. And the degree 6 indicates that the rock material has become completely weathered. These methods in the prior art use visual classification based on field observation and based entirely on the experience of the researcher.
Chinese patent document No. CN106525961 discloses a method for detecting the turbidity of water by a sensor. Two ultrasonic sensors, an a and a B sensor, are used in the method. The two sensors are symmetrically distributed at two ends of the shaft by a distance L. Sensor a sends an ultrasonic signal to sensor B on a fixed excitation axis. As the turbidity in the water increases, the scattering of the waves increases due to the increase of particles in the water. In this case, the signal strength received by the sensor B decreases. The turbidity can be calculated from the relationship of the calibrated turbidity and the amplitude of the voltage signal received by sensor B. The turbidity of water can be measured in any state, provided that the turbidity and signal intensity have the correct calibration relationship.

When the power button (5) is triggered, the infrared sensor (8) starts to measure when it receives the necessary energy from the power supply located on the power socket (3).
The weathering classification apparatus (1) of the invention comprises two tubes (T) in which there is water and a weathered or non-weathered rock sample within a body (2). Wherein a rock sample is located in a tube (T) on the body (2), the rock sample collected from the field being intended to measure the turbidity it gives to the water. In a preferred embodiment, two tubes (T) are contained on the body (2), wherein the non-weathered rock sample is located in the first and the weathered sample is located in the second together with water.
In a preferred embodiment of the invention, the body (2) is portable, lightweight, and may be used in the field. The tube (T) used on the body (2) is made of plastic material. Thus, the pipe (T) is prevented from breaking under terrestrial conditions. Preferably, the body (2) has a waterproof structure.
The power supply is located on the main body (2), in the power supply groove (3), and is two AA batteries which supply the required electric energy for the infrared sensor (8), the control unit (13) and the imaging part (4).
In a preferred embodiment of the invention, the control unit (13) comprises a microcontroller unit, a USB socket, an input voltage of 9 volts, an amplifier of 3 to 9 volts, an infrared sensor voltage signal amplifier and a tilt sensor. An input voltage of 9 volts on the control unit (13) provides the power required by the device when the adapter is connected.
In a preferred embodiment of the invention, the infrared sensor (8) generates a voltage dependent on the intensity of the radiation emitted by the infrared light source (9). An infrared sensor (8) measures the turbidity of the water based on the generated voltage value. The infrared sensor (8) shares voltage data from an undegraded rock sample to a sample completely converted to soil with the control unit (13) for classification. In a preferred embodiment, the control unit (13) performs a weathering classification assessment between 1-6 figures displayed on the imaging means (4) by processing the data received from the infrared sensor (8). The control unit (13) displays the weathered sample of the 6 th degree as the residual soil on the imaging part (4).
In the weathering classification apparatus (1) of the invention, an infrared sensor (8) is located on a sensor card (10) and within a sensor container (7) such that the infrared sensor (8) is located in the upper part of the tube (T) in order to measure the turbidity of the rock in the water. The infrared sensor (8) measures based on the principle of the decomposition of rock samples in water and the turbidity of the water. Rock samples are placed in the sample tube (T) in the lower part of the body (2) so that they do not exceed the low level line, and water is filled to a high level. Triggering a tilt sensor located on the control unit (13) when the main body (2) is rotated 180 ° in the vertical position; turbidity is generated by mixing a rock sample inside the tube (T) with water, and an infrared sensor (8) measures the turbidity generated in the tube (T), e.g. in water. Therefore, the control unit (13) determines the rock weathering degree from the transparency value of water inside the pipe (T) in which the non-weathered rock is placed and the turbidity value of water inside the pipe (T) in which the weathered rock is placed, by using the voltage value data obtained by the infrared sensor (8).
In a preferred embodiment of the invention, the control unit (13) classifies samples from non-weathered rock samples to samples converted into soil by using voltage data received from the infrared sensor (8). In a preferred embodiment, the control unit (13) determines the degree of efflorescence by means of a numerical value. Preferably, the control unit (13) displays a value of between 1 and 6 of the efflorescence degree on the imaging member (4).
In the weathering classification apparatus (1) of the invention, the control unit (13) first receives voltage data (V1 and V2) from the infrared sensor (8), receives a voltage value (V1) from the tube (T) in which the non-weathered sample is located, and receives another voltage value (V2) from the tube (T) in which the weathered sample is located. The control unit (13) subtracts the voltage value (V2) received from the tube (T) in which the weathered sample is located from the voltage value (V1) received from the un-weathered sample and obtains a result (V1-V2).
The imaging means (4) is a screen that displays as a numerical value the degree of weathering of a rock sample located on the body (2) received from the control unit (13) and detected by the control unit (13) from a specific voltage value.
The weathering classification apparatus (1) of the invention operates on the principle of the decomposition of weathered rock samples in water and on the turbidity of the water. The non-weathered rock sample is located in one tube (T) placed on the body (2) and the weathered sample is located in the other tube together with the water. An infrared sensor (8) is positioned on the body (2) so that it is positioned above the tube (T) to measure the turbidity generated in the tube (T) and transmit it to the control unit (13). The control unit (13) compares the transparency of the water in the tube (T) in which the non-weathered rock is placed with the turbidity of the water in the tube (T) in which the weathered sample is placed. The control unit (13) performs comparison processing by using the voltage value, and notifies the obtained classification value to the user on the imaging section (4) as a screen.
With the weathering classification apparatus (1) of the invention, standard evaluation by portable devices is ensured without performing the rock weathering classification process based on the experience of the researcher. Moreover, the present invention can be easily applied in the field, and it has a portable structure suitable for a palm. The weathering classification apparatus (1) of the present invention determines the degree of rock weathering in a short time, and it can classify more samples in a short time by repeating experiments at specific intervals.
