Description

Technical Field

[0001] The utility model relates to the technical field of hole measuring devices, in particular to a multi-parameter hole measuring device. Background Art

[0002] Currently, in open-pit deep-hole blasting projects, in order to ensure safety and efficiency, pre-drilled blastholes are usually inspected using a rope ruler or blasthole detection device. This method can help determine the depth of the blasthole to ensure that the blasting operation proceeds as planned.

[0003] While many hole-measuring aids exist, they all suffer from incomplete parameter information and, due to their complex design or principles, high rates of damage and failure at construction sites. For example, hole-measuring devices often utilize a combination of a rope and a weight. This method can only determine whether the hole is blocked and its depth, is labor-intensive, and inefficient. Furthermore, measuring the critical parameter of hole inclination, such as pre-cracked and smooth holes, is difficult. Often, the hole bottom is only discovered after blasting is complete, negatively impacting acceptance. Furthermore, they are unable to timely measure the water depth and temperature within the hole, both of which significantly impact the type and quantity of subsequent explosive charges. Consequently, existing hole-measuring aids struggle to meet today's trends toward intelligent and digital development. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a multi-parameter hole measuring device which can measure multiple parameters of a blasthole.

[0005] In order to solve the above technical problems, the present invention provides a multi-parameter hole measuring device adopting the following technical solutions:

[0006] A multi-parameter hole measuring device includes a bracket, a position sensor module arranged on the bracket, a measuring rope sleeve rotatably connected to the bracket, a measuring rope wound on the measuring rope sleeve, and a data acquisition and processing unit fixed to the measuring rope, wherein the position sensor module is used to determine the number of rotations of the measuring rope sleeve; the data acquisition and processing unit includes a general control module arranged on the measuring rope, a temperature sensor module electrically connected to the general control module, a water depth sensor module and / or a posture sensor module, the temperature sensor module includes a temperature sensor, the water depth sensor module includes a water pressure sensor, and the posture sensor module includes a gyroscope.

[0007] By adopting the above-mentioned technical solution, the measuring rope sleeve is driven to rotate, allowing the measuring rope wrapped around it to be lowered or retrieved, allowing the measuring rope and data acquisition and processing unit to be lowered into the borehole until it reaches the bottom. At this point, the position sensor module measures the rotational circle of the measuring rope sleeve to determine the length of the lowered measuring rope and thus the borehole depth. A temperature sensor, water pressure sensor, and gyroscope are also used to measure the borehole temperature, water depth, and inclination. After reaching the bottom of the hole, the data acquisition and processing unit retracts the measuring rope and extracts the processed information, thereby obtaining multiple measurement parameters for the borehole. This provides more comprehensive and detailed guidance parameters for subsequent blasting and charging operations, ensuring the smooth progress of blasting operations.

[0008] Optionally, the bracket is fixedly provided with a sleeve control module, the sleeve control module includes a motor power supply, a motor master control electrically connected to the motor power supply, and a motor electrically connected to the motor master control, and the measuring rope sleeve is fixed to the output shaft of the motor.

[0009] By adopting the above technical solution, the motor power supply provides power source for the motor master control and the motor, and the opening and closing of the motor are controlled by the motor master control, so that the measuring rope can be lowered and recovered more efficiently, thereby improving the measurement efficiency.

[0010] Optionally, the position sensor module includes a position sensor and a position sensor signal disk vertically fixed to the measuring rope sleeve. The position sensors are fixed relative to the bracket, and the position sensors can sense changes in the magnetic field of the position sensor signal disk.

[0011] By adopting the above technical solution, since the position sensor signal disk is vertically fixed to the measuring rope sleeve, the position sensor signal disk and the measuring rope sleeve rotate at the same angular velocity. The position sensor can sense the changes in the magnetic field when the position sensor signal disk rotates to obtain the number of rotations of the measuring rope sleeve.

[0012] Optionally, the master control module includes a master control battery, a master control processor electrically connected to the master control battery, and a master control storage signal-connected to the master control processor, and the temperature sensor module, water depth sensor module and / or posture sensor module are all signal-connected to the master control processor.

[0013] By adopting the above technical solution, the master control battery provides unified power supply to the temperature sensor module, water depth sensor module and / or attitude sensor module. The signals of the temperature sensor module, water depth sensor module and / or attitude sensor module are fed back to the master control processor for centralized processing and stored in the master control storage, thereby promoting efficient acquisition and processing of measurement data.

[0014] Optionally, the master control processor includes a data processor and Bluetooth electrically connected to the master control battery, and the master control storage signal is connected to the data processor and Bluetooth.

[0015] By adopting the above technical solution, the data processor is used to process the original signals fed back by the temperature sensor module, the water depth sensor module and / or the attitude sensor module, and Bluetooth is used to exchange information with an external signal receiving device, so that information can be directly fed back to the external signal receiving device outside the borehole while the measuring rope is still in the borehole, further improving the measurement efficiency.

[0016] Optionally, the number of the temperature sensors is at least two, and the signals of at least two temperature sensors are both connected to the master control processor.

[0017] By adopting the above technical solution, at least two temperature sensors can verify the measurement data, and the signal difference of at least two temperature sensors can be analyzed and settled to determine whether there is a deviation in the measurement data, thereby improving the measurement accuracy of the temperature in the hole.

[0018] Optionally, the number of the water pressure sensors is at least two, and the signals of at least two water pressure sensors are both connected to the master control processor.

[0019] By adopting the above technical solution, at least two water pressure sensors can verify the measurement data, and the signal difference between at least two water pressure sensors can be analyzed and settled to determine whether there is a deviation in the measurement data, thereby improving the measurement accuracy of the water depth in the hole.

[0020] Optionally, the water depth sensor module also includes a light source and a light signal receiving sensor, the light source and the light signal receiving sensor are located on the same straight line and are arranged facing each other, there is an angle between the straight line where the light source is located and the horizontal line, and the light signal receiving sensor signal is connected to the main control processor.

[0021] By adopting the above technical solution, the water pressure sensor's detection is affected by flow interference. A light source emits a light beam, which is received by an optical signal receiving sensor. When the water depth sensor module is submerged in water, the light beam emitted by the light source is refracted in the water. The optical signal receiving sensor receives the refracted light beam and uses the change in the light beam's refractive index upon entry into the water to determine the water depth. This effectively verifies and supplements the water pressure sensor's measurement data and can determine whether the borehole contains still water or flowing water.

[0022] Optionally, there are at least two gyroscopes, and at least two gyroscopes are signal-connected to the master control processor.

[0023] By adopting the above technical solution, at least two gyroscopes can verify the measurement data, and the signal difference of at least one gyroscope can be analyzed and settled to determine whether there is a deviation in the measurement data, thereby improving the measurement accuracy of the hole inclination angle.

[0024] Optionally, a rubber pad is provided at the end of the data acquisition and processing unit away from the measuring rope.

[0025] By adopting the above technical solution, the rubber pad can cushion the impact received by the data acquisition and processing unit when it reaches the bottom of the hole, thereby reducing the possibility of damage to the data acquisition and processing unit and extending its service life.

[0026] In summary, the present invention has at least one of the following beneficial technical effects:

[0027] 1. The position sensor module measures the rotation of the measuring rope sleeve to determine the length of the measuring rope lowered, thereby measuring the depth of the drilled hole. The temperature sensor, water pressure sensor, and gyroscope can also be used to measure the borehole temperature, water depth, and inclination of the borehole.

[0028] 2. At least two temperature sensors, water pressure sensors, and gyroscopes can verify the measurement data and analyze and settle their signal differences to determine whether there is any deviation in the measurement data, thereby improving the measurement accuracy of the hole temperature, water depth, and hole inclination;

[0029] 3. The rubber pad can cushion the impact received by the data acquisition and processing unit when it reaches the bottom of the hole, thereby reducing the possibility of damage to the data acquisition and processing unit and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-6 The utility model is described in further detail.

[0038] The present invention discloses a multi-parameter hole measuring device. Figure 1 The multi-parameter borehole measurement device includes a bracket 1, which includes two supports 11 and two fixed shafts 12. The two supports 11 are parallel to each other and have their upper and lower edges flush. The two fixed shafts 12 are located between the two supports 11 and are vertically fixed to the two supports 11. One of the fixed shafts 12 is fixedly provided with a housing 34, and the other fixed shaft 12 is covered with a measuring rope sleeve 2 and rotatably connected thereto. The bracket 1, fixed shaft 12, and housing 34 are made of stainless steel, copper, or rust-proof cast iron. In the embodiment of the present application, stainless steel is used.

[0039] Reference Figure 1 and Figure 2 The housing 34 houses the sleeve control module 3, which includes a motor power supply 31, a motor master control 32, and a motor 33. The motor power supply 31, motor master control 32, and motor 33 are all fixedly mounted within the housing 34. The motor master control 32 is electrically connected to the motor power supply 31, and the motor 33 is electrically connected to the motor master control 32. One end of the measuring rope sleeve 2 is fixedly connected to the output shaft of the motor 33. A first control switch 35 is located on the outer wall of the housing 34 and is electrically connected to the motor master control 32 and the motor power supply 31.

[0040] Reference Figure 1 A measuring rope 21 is wound around the measuring rope sleeve 2. One end of the measuring rope 21 is fixedly connected to the measuring rope sleeve 2, and the other end of the measuring rope 21 is provided with a data acquisition and processing unit 5. The measuring rope 21 is made of high-strength nylon rope or steel wire rope and is replaced regularly to ensure reliability.

[0041] Reference Figure 1 and Figure 2 A position sensor module 4 is disposed between the two fixed shafts 12. This module includes a position sensor signal disk 42 and two position sensors 41. The two position sensors 41 are fixedly mounted within the housing 34, surrounding the fixed shafts 12 and aligned vertically. Both position sensors 41 are connected to the motor master control 32 via the first signal bus 36. The position sensor signal disk 42 is vertically fixed to the measuring rope sleeve 2 and has multiple magnets circumferentially disposed thereon.

[0042] The position sensor signal disk 42 rotates at the same angular velocity as the rope measuring sleeve 2. The position sensor 41 can sense the change in the magnetic field when the position sensor signal disk 42 rotates to obtain the number of rotations of the rope measuring sleeve 2, thereby being able to determine the lowering length of the rope measuring sleeve 21.

[0043] Reference Figure 1 One end of the measuring rope 21 is fixedly connected to a protective housing 55. The protective housing 55 is a metal cylindrical structure that is waterproof to IPX8. The diameter of the protective housing 55 is less than 28 mm. In the embodiment of the present application, the diameter of the protective housing 55 is 25 mm. The data acquisition and processing unit 5 is installed in the protective housing 55.

[0044] Reference Figure 1 and Figure 3 The data acquisition and processing unit 5 includes a master control module 51, a temperature sensor module 52, a water depth sensor module 53, and a posture sensor module 54. These three modules are sequentially arranged inside a protective housing 55 from top to bottom. The master control module 51 includes a master control battery 511, a master control processor 512, and a master control storage 513. The master control processor 512 is electrically connected to the master control battery 511, and the master control storage 513 is signal-connected to the master control processor 512. A second control switch 56 is provided on the upper end surface of the protective housing 55. The second control switch 56 is electrically connected to the master control battery 511 and the master control processor 512.

[0045] Reference Figure 1 and Figure 4 The temperature sensor module 52 includes two temperature sensors 521 installed inside the protective shell 55. The two temperature sensors 521 are arranged in a horizontal direction. The two temperature sensors 521 are connected to the main control processor 512 through the second signal bus 57. The temperature measurement range of the temperature sensor 521 is -50-80℃.

[0046] The temperature sensor 521 can measure the temperature inside the hole. The two temperature sensors 521 can verify the measurement data and analyze and settle the signal difference between the two temperature sensors 521 to determine whether there is any deviation in the measurement data, thereby improving the measurement accuracy of the temperature inside the hole.

[0047] Reference Figure 1 and Figure 5 The water depth sensor module 53 includes a light source 532, an optical signal receiving sensor 533, and two water pressure sensors 531. A mounting bracket 534 is fixedly mounted within the protective housing 55. The light source 532, the optical signal receiving sensor 533, and the two water pressure sensors 531 are collectively mounted on the mounting bracket 534. The mounting bracket 534 is a rectangular structure with a hollowed-out design. The light source 532 and the optical signal receiving sensor 533 are respectively disposed on two separate sides of the mounting bracket 534, and the two water pressure sensors 531 are respectively disposed on two separate sides of the mounting bracket 534.

[0048] Reference Figure 5 The light source 532 and the optical signal receiving sensor 533 are located on the same straight line. The light-emitting end of the light source 532 and the receiving end of the optical signal receiving sensor 533 are positioned facing each other. The straight line containing the light source 532 is at a 45° angle to the horizontal. The optical signal receiving sensor 533 is connected to the master control processor 512. The mounting bracket 534 does not interfere with the optical signal receiving sensor 533 receiving the light source 532. There is a fixed height difference between the two water pressure sensors 531. The two water pressure sensors 531 are connected to the master control processor 512 via a second signal bus 57. The water pressure sensor 531 has a pressure measurement range of 0-500 kPa.

[0049] The water pressure sensor 531 measures the water depth in the hole. The two water pressure sensors 531 can verify the measurement data and analyze and settle the signal difference between the two water pressure sensors 531 to determine whether there is a deviation in the measurement data, thereby improving the accuracy of measuring the water depth in the hole. Due to the flow interference of the fluid on the detection of the water pressure sensor 531, a light source 532 is used to emit a light beam, and an optical signal receiving sensor 533 receives the light beam. After the water depth sensor module 53 enters the water, the light beam emitted by the light source 532 is refracted in the water. The optical signal receiving sensor 533 receives the refracted light beam and uses the change in the refractive index of the light beam when it enters the water to determine the water depth. This can effectively verify and supplement the measurement data of the water pressure sensor 531, and can determine whether there is still water or flowing water in the borehole.

[0050] Reference Figure 1 and Figure 6The attitude sensor module 54 includes two gyroscopes 541 mounted within a protective housing 55. The two gyroscopes 541 are arranged vertically and connected to the master control processor 512 via a second signal bus 57. The gyroscopes 541 are capable of measuring the hole inclination angle, verifying the measurement data, and analyzing and calculating the signal difference between at least one gyroscope 541 to determine whether the measurement data has deviations, thereby improving the accuracy of hole inclination angle measurement.

[0051] Position the bracket 1 at the edge of the borehole to be inspected, turn on the second control switch 56, place the measuring rope 21 and data acquisition and processing unit 5 into the borehole, turn on the first control switch 35, and control the motor 33 to lower the measuring rope 21 to the bottom of the borehole. At this point, the position sensor module 4 measures the rotation of the measuring rope sleeve 2 to determine the length of the lowered measuring rope 21 and thus the borehole depth. The temperature sensor 521, water pressure sensor 531, and gyroscope 541 can also measure the borehole temperature, water depth, and inclination. After reaching the bottom of the hole, the data acquisition and processing unit 5 retracts the measuring rope 21 and extracts the processed information, thereby obtaining multiple measurement parameters for the borehole. This provides more comprehensive and detailed guidance for subsequent blasting and charging operations, ensuring smooth blasting operations.

[0052] Reference Figure 3 To improve measurement efficiency, the master control processor 512 includes a data processor 5121 and a Bluetooth device 5122. These devices are electrically connected to the master control battery 511, and the master control storage 513 is signal-connected to the data processor 5121 and Bluetooth device 5122. The data processor 5121 processes the raw signals fed back by the temperature sensor module 52, the water depth sensor module 53, and the attitude sensor module 54. The Bluetooth device 5122 is used to exchange information with an external signal receiving device. This allows the measuring line 21 to directly transmit information to an external signal receiving device outside the borehole while it remains inside the borehole, further improving measurement efficiency.

[0053] Reference Figure 1 To extend the service life of the data acquisition and processing unit 5, a rubber pad 551 is fixedly attached to the end of the protective shell 55 away from the measuring rope 21. The rubber pad 551 cushions the impact of the data acquisition and processing unit 5 when it reaches the bottom of the hole, thereby reducing the possibility of damage to the data acquisition and processing unit 5 and extending its service life.

[0054] The multi-parameter borehole measurement device of the present invention is implemented as follows: The bracket 1 is positioned at the edge of the borehole to be inspected, the second control switch 56 is turned on, the measuring rope 21 and the data acquisition and processing unit 5 are placed in the borehole, the first control switch 35 is turned on, and the motor 33 is controlled to lower the measuring rope 21 to the bottom of the borehole. At this point, the position sensor module 4 measures the rotational circle of the measuring rope sleeve 2 to determine the lowered length of the measuring rope 21 and thus the borehole depth. The temperature sensor 521, the water pressure sensor 531, and the gyroscope 541 can also be used to measure the borehole temperature, water depth, and inclination. After reaching the bottom of the hole, the data acquisition and processing unit 5 retracts the measuring rope 21 and extracts the processed information, thereby obtaining multiple measured parameters for the borehole. This provides more comprehensive and detailed guidance parameters for subsequent blasting and charging operations, thereby better ensuring the smooth progress of the blasting operation.

[0055] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
