Detailed Description
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
The invention relates to a slope-measuring system for geological drilling, which is used for measuring the numerical value of a geological drilling hole at a depth to be measured, as shown in figure 1, and comprises a first device 1 which is statically arranged in the drilling hole, wherein the first device 1 comprises a first control unit 11, and an acoustic wave transmitting unit 12, an electronic gyro unit 13 and an electronic compass unit 14 which are respectively and electrically connected with the first control unit 11; wherein the sound wave transmitting unit 12 measures the hole depth of the drilled hole by using the sound wave time difference; the electronic gyro unit 13 includes a three-axis attitude measuring unit for measuring a hole inclination of the drilled hole; the electronic compass unit 14 measures the azimuth of the borehole according to the principle of geomagnetism.
In the above embodiment, the first apparatus 1 is placed still in the borehole, and it is an electronic integrated apparatus, and the hole depth, hole inclination and orientation of the borehole are measured by the acoustic wave emitting unit 12, the electronic gyro unit 13 and the electronic compass unit 14 provided therein, respectively. Specifically, the first control unit 11 may be a single chip microcomputer or a CPU, and is configured to process and store data collected by the sound wave emitting unit 12, the electronic gyro unit 13, and the electronic compass unit 14. The acoustic transmitter unit 12 includes an acoustic transmitter that measures the depth of the borehole using the time difference of sound propagation. The electronic gyro unit 13 includes a three-axis attitude measurement unit, which may be a three-axis attitude sensor, and is capable of rapidly measuring three-dimensional angles and vibrations of XYZ in space in real time. The electronic compass unit 14 is a method for determining the north pole by using a geomagnetic field, and acquired data can be directly displayed through a nixie tube; in particular, a three-axis strapdown magnetoresistive digital magnetic compass can be used, which has the advantages of anti-shake and anti-vibration, high precision, and electronic compensation of interfering magnetic fields. The inclination measuring system is an electronic integrated device, has high measuring precision, can simultaneously measure the hole depth, the hole inclination and the direction, and is convenient and quick.
In a preferred embodiment of the invention, as shown in figure 2, the inclinometer system further comprises a second device 2 located at the surface for receiving and displaying data acquired by the first device 1 from a remote location. Specifically, the first device 1 sends the acquired data to the second communication unit 25 of the second device 2 through the first communication unit 16 provided therein, and this communication mode may be a wireless communication mode. In this embodiment, the second device 2 is held by a measurer on the ground surface, and the data collected by the first device 1 can be read in real time through the liquid crystal display 22 arranged on the second device 2, which is convenient and fast, and the collecting device does not need to be extracted to the ground for reading as in the prior art.
In a preferred embodiment of the present invention, the first device 1 further comprises an infrared camera unit 15 connected to the first control unit 11, for taking and/or recording pictures of the conditions inside the borehole, and then transmitting the pictures or videos to the display screen 22 for display. The infrared camera unit 15 may be a high-definition digital camera. In the process of descending the first device 1 into the borehole and performing measurement in the borehole, the measurement personnel need to know the first device 1 and the overall situation in the borehole in time, for example, need to know whether there is an obstacle in the borehole, the position where the first device 1 can stand, and the like. Therefore, the infrared imaging unit 15 can grasp the information in time.

In this embodiment, since the first device 1 may be in a borehole having a depth of up to several hundred meters, if no command is sent to the first device 1, the first device 1 will collect data to the second device 2 without detecting conditions, and the second device 2 will receive more inaccurate redundant data. Enumerating the specific application scenarios of the embodiment: when the picture or video acquired by the infrared camera unit 15 shows that the first device 1 has reached the drill hole with the depth to be measured, the instruction sending unit 24 sends a measurement starting instruction to the first device 1, and the first device 1 performs measurement after receiving the instruction for a predetermined time, so as to ensure that the first device 1 performs measurement in a standing state. When the drilling measurement of the depth to be measured is finished, the instruction transmitting unit 24 transmits a measurement stop instruction to the first device 1. The operation mode not only ensures the accuracy of the measured data, but also reduces the data redundancy and improves the working efficiency.
In a preferred embodiment of the present invention, the first device 1 measures the hole depth, hole inclination and hole orientation of the drilled hole at predetermined time intervals within a predetermined time period, and calculates the average value corresponding to each parameter within the predetermined time period. For the drilling holes with the same depth to be measured, the accuracy of the measured data can be improved through multiple measurements. For example, in a specific application, the first control unit 11 controls the sound wave emitting unit 12, the electronic gyro unit 13 and the electronic compass unit 14 to collect data every 2 seconds or 5 seconds, the whole collection time does not exceed 10 minutes, and when the set time is 10 minutes, the measurement is stopped; or when the difference between the average value obtained by the first control unit 11 and the value measured next time is larger than the set error, the measurement is stopped.
In a preferred embodiment of the invention, the inclinometer system measures the borehole data at predetermined intervals and depths. Usually, the geological exploration depth is 200-1000 m, and the local depth reaches 2000 m. In the invention, the predetermined interval depth can be reasonably set according to the total exploration depth, for example, the measurement is carried out every 50 meters, 80 meters or 100 meters, so that the overall track data of the whole geological body can be obtained.
In the preferred embodiment of the present invention, after the drilling values of all depths to be measured are measured, the first device 1 is lifted to the ground. In conventional measurement methods, each time a borehole is measured to a depth to be measured, the device needs to be retrieved to the surface. According to the inclination measuring system, the first device 1 and the second device 2 can transmit data in real time in a wireless mode, and the tedious operation of repeatedly lifting the first device 1 to the ground is avoided.
