Description

Technical Field

[0001] The present invention relates to the technical field of mine surveying, and more particularly to a mine surveying benchmark correction device. Background Art

[0002] In the process of mine exploration in my country, geological survey, heavy sand survey, geochemical prospecting, geophysical prospecting, remote sensing geological survey and engineering exposure are often used. The above methods are used to delineate the places where mineral resources may exist, and then drill holes to take soil samples. The geological structure, landform, hydrogeological conditions, and physical and mechanical properties of soil and rock are studied by studying soil samples.

[0003] The existing Chinese patent CN113608277B discloses a mine survey benchmark correction device, which is used to manually select benchmark points and benchmark surfaces, and then judge whether the setting of benchmark points or benchmark surfaces is reasonable by the brightness of the light, so as to correct the accuracy of the actual drilling depth and improve the accuracy of the overall survey data. The device provided in the patent presents whether the benchmark surface is sloped or flat, which is difficult for the human eye to judge, in the form of light brightness. The inventor of the patent adjusts the size of the resistor to make the light brightness show a large difference, and only opens the front side of the observation cavity to make it dark inside, making the light brightness easier to distinguish.

[0004] However, it is actually quite difficult to distinguish the brightness of the light in the device with the naked eye, mainly for the following reasons:

[0005] 1. All lights are located inside the observation chamber. When multiple lights are on at the same time, the light emitted converges together, making the entire observation chamber very bright. It is difficult to distinguish the brightness of the lights with the naked eye.

[0006] 2. Mining surveys are usually conducted outdoors. To ensure the safety of surveyors, they are rarely conducted at night or in bad weather. Therefore, surveys are often conducted when the sun is brighter. When the sun is brighter, the difference in light brightness will be affected by the sun and become smaller, making it more difficult to distinguish. Summary of the invention

[0007] The purpose of the present invention is to provide a mine survey benchmark correction device, which can directly present whether the benchmark surface has a slope through data, solving the problem of relying on the naked eye to identify the light brightness to determine whether the benchmark surface has a slope in the prior art, while also avoiding the problem of inaccurate drilling depth and inaccurate survey results caused by inaccurate naked eye recognition.

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: a mine survey benchmark correction device, comprising a connecting plate, a support rod and a horizontal plate, the connecting plate having a built-in battery, a charging port and a control keyboard on the front of the connecting plate, connecting components symmetrically arranged on both sides of the connecting plate, each of the connecting components being fixedly connected to a support rod, the bottom of the support rod being fixedly connected to a limited depth plate, a positioning rod being arranged at the bottom of the depth limit plate; a telescopic rod one and a telescopic rod two being symmetrically arranged at the bottom of the connecting plate, the tails of the telescopic rod one and the telescopic rod two being respectively connected to the two ends of the horizontal plate, a U-shaped tube being arranged at the top of the horizontal plate, a movable groove being arranged in the horizontal plate, a current monitor being arranged at the top of the movable groove, a wire coil and a permanent magnet being arranged in the movable groove, the two ends of the wire coil being connected to an ammeter, a push rod being fixedly connected to the bottom of the permanent magnet, and a buffer ball being arranged at the tail of the push rod.

[0009] By adopting the above technical solution, a battery is provided to provide the power required by the device, a charging port is provided to charge the battery, a control keyboard is provided to operate telescopic rod 1 and telescopic rod 2, and telescopic rod 1 and telescopic rod 2 are provided to facilitate adjustment of the horizontal plate to ensure that the horizontal plate is level. The horizontal plate is provided to ensure that the buffer balls are located in the same horizontal plane. A connecting assembly is provided to connect the connecting plate and the support rod, the support rod is provided to support the device, a connecting plate is provided to connect various parts of the device, a depth limiting plate is provided to limit the depth of the positioning rod inserted into the soil, and a positioning rod is provided to be inserted into the soil to fix the entire device.

[0010] After the buffer ball touches the ground, the telescopic rod 1 and the telescopic rod 2 are simultaneously regulated to move down the same distance. Since the buffer ball is blocked by the ground, it will trigger the telescopic rod to push the permanent magnet to move in the movable groove. Since a wire coil is arranged in the movable groove, and an ammeter is connected to both ends of the wire coil, a closed circuit is formed. When the permanent magnet passes through the middle of the wire coil, the wire coil cuts the magnetic flux of the permanent magnet, generates a current, and the magnitude of the current is displayed on the ammeter, which is recorded by the current monitor and displayed on the liquid crystal display. Since the magnitude of the current in Faraday's law of electromagnetic induction is affected by factors such as the speed of wire cutting, the speed direction of wire cutting, the strength of the permanent magnet, the number of turns of the wire coil, and the effective length of the wire cut, in the present invention, the speed direction of wire cutting is fixed, the strength of the permanent magnet and the effective length of the wire cut are also the same, and the speed of wire cutting is equal to the speed of extension of the telescopic rod 1 and the telescopic rod 2, so the speed of movement of all permanent magnets is the same, that is, the speed of wire cutting is the same. Therefore, the only factor that affects the current size is the number of turns of the cutting wire coil, and the distance that the push rod pushes the permanent magnet to move is positively correlated with the number of turns of the cutting wire coil. Therefore, the current size actually reflects the activity distance of the permanent magnet, and the difference in the distance of the permanent magnet activity at different positions is the height difference of the corresponding positions of the reference surface.

[0011] The device can directly display whether the reference surface has a slope through data, which solves the problem of relying on the naked eye to identify the light brightness to determine whether the reference surface has a slope in the prior art. It also avoids the problem of inaccurate drilling depth and inaccurate survey results caused by inaccurate naked eye recognition.

[0012] The present invention is further configured as follows: an opening is provided at the bottom of the movable groove, the push rod passes through the opening and is connected to the permanent magnet, the diameter of the opening is larger than the diameter of the push rod, and the diameter of the opening is smaller than the diameter of the permanent magnet.

[0013] By adopting the above technical solution, the opening at the bottom of the movable groove can allow the push rod to move, but because its diameter is larger than the push rod and smaller than the permanent magnet, the permanent magnet is always located inside the movable groove no matter how the push rod moves.

[0014] The present invention is further configured as follows: the push rod is made of any one of thermoplastic polyurethane, thermosetting polyurethane, thermoplastic polyolefin plastic or thermoplastic polyester plastic.

[0015] By adopting the above technical solution, the above materials are all electromagnetic shielding materials, which will not interfere with electromagnetic phenomena and cause inaccurate readings of the ammeter.

[0016] The present invention is further configured as follows: the material of the buffer ball is any one of polystyrene foam plastic, polyethylene foam plastic or polyurethane foam plastic.

[0017] By adopting the above technical solution, the above materials are all lightweight materials and will not compress the reference surface when contacting the reference surface.

[0018] The present invention is further configured as follows: a holographic instant scanner is provided at the bottom of the current monitor, an image information receiving device and an image recognition processing device are built into the current monitor, a liquid crystal display is provided on the outer surface of the horizontal plate, and an output end of the image recognition processing device is connected to the liquid crystal display.

[0019] By adopting the above technical solution, the holographic instant scanner can take multiple photos instantly and capture the instantaneous reading of the ammeter. The multiple photos taken are then received by the information receiving device, and the empirical image recognition and processing device reads the ammeter reading and presents it on the LCD screen for surveyors to read.

[0020] The present invention is further configured as follows: the U-shaped tube includes a horizontal tube, a first vertical tube and a second vertical tube, the first vertical tube is provided with a first scale line, the top of the first vertical tube is provided with a first sealing opening, the second vertical tube is provided with a second scale line, and the top of the second vertical tube is provided with a second sealing opening.

[0021] By adopting the above technical solution, liquid is put into the U-shaped tube, and the first sealing port and the second sealing port are opened. Under the influence of atmospheric pressure, the height of the liquid in the first vertical tube and the second vertical tube of the U-shaped tube should be consistent. If there is a difference in the readings displayed by the first scale line and the second scale line, it proves that the U-shaped tube is not horizontal, and further proves that the horizontal plane is not leveled. By adjusting the telescopic rod 1 and the telescopic rod 2 until the readings of the first scale line and the second scale line are consistent, the horizontal plane is leveled, and the buffer balls are located in the same plane.

[0022] The present invention is further configured as follows: the output end of the control keyboard is connected to the first telescopic rod and the second telescopic rod.

[0023] By adopting the above technical solution, the movement of the telescopic rod 1 and the telescopic rod 2 can be controlled by controlling the keyboard.

[0024] In summary, the present invention has the following beneficial effects: the present invention is designed based on Faraday's law of electromagnetic induction, generates current by cutting the magnetic flux lines of the permanent magnet through the wire coil, and then takes the reading of the ammeter through the holographic instant scanner and presents it on the liquid crystal display. In this device, permanent magnets with the same magnetic properties and wire coils with the same specifications are selected, and the cutting speed is controlled by telescopic rods 1 and 2, so that the only factor that can affect the current size is the number of turns of the cutting wire coil, and this data is positively correlated with the distance that the permanent magnet moves in the active slot, so the current size reflects the distance that the permanent magnet moves in the active slot, and the current size difference at different positions feeds back the height difference of the corresponding positions of the reference surface.

[0025] The device provided by the present invention intuitively presents whether the reference surface has a slope through data, which solves the problem of relying on the naked eye to identify the light brightness to determine whether the reference surface has a slope in the prior art, and also avoids the problem of inaccurate drilling depth and inaccurate survey results caused by inaccurate naked eye recognition.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-10 The present invention is described in further detail.

[0038] Embodiment: A mine survey benchmark correction device, such as Figure 1-10As shown, it includes a connecting plate 5, a support rod 3 and a horizontal plate 11. The connecting plate 5 is equipped with a built-in storage battery 23 to provide the power required by the device. A charging port 6 and a control keyboard 7 are provided on the front of the connecting plate 5. The output end of the control keyboard 7 is connected to the telescopic rod 1 8 and the telescopic rod 2 9. Two connecting components 4 are symmetrically provided on both sides of the connecting plate 5. Each connecting component 4 is fixedly connected to a support rod 3. The bottom of the support rod 3 is fixedly connected to the limited depth plate 2. The bottom of the limited depth plate 2 is provided with a positioning rod 1. The bottom of the connecting plate 5 is symmetrically provided with a telescopic rod 1 8 and a telescopic rod 2 9. The tails of the telescopic rod 1 8 and the telescopic rod 2 9 are respectively connected to the two ends of the horizontal plate 11. The horizontal plate 11 is provided with a movable groove 19. The top of the movable groove 19 is provided with a current monitor 20. The movable groove 19 is provided with a wire coil 17 and a permanent magnet 18. The two ends of the wire coil 17 are connected to an ammeter 16. The bottom of the permanent magnet 18 is fixedly connected to a push rod 13. The tail of the push rod 13 is provided with a buffer ball 14. An opening 24 is provided at the bottom of the movable slot 19 , and the push rod 13 passes through the opening 24 to connect with the permanent magnet 18 . The diameter of the opening 24 is larger than the diameter of the push rod 13 , and smaller than the diameter of the permanent magnet 18 .

[0039] In order to more quickly measure whether the reference surface is flat, two rows of movable grooves 19 are provided in the horizontal plate 11 , one row is close to the front side of the horizontal plate 11 , and the other row is close to the back side of the horizontal plate 11 .

[0040] In order to facilitate observation of whether the horizontal plate 11 is leveled, a U-shaped tube 10 is arranged on the top of the horizontal plate 11 in this embodiment. The U-shaped tube 10 includes a horizontal tube 1001, a first vertical tube 1002 and a second vertical tube 1003. The first vertical tube 1002 is provided with a first scale line 1004, and the top of the first vertical tube 1002 is provided with a first sealing port 1006. The second vertical tube 1003 is provided with a second scale line 1005, and the top of the second vertical tube 1003 is provided with a second sealing port 1007.

[0041] In this embodiment, a holographic instant scanner 15 is provided at the bottom of the current monitor 20 for capturing the reading of the ammeter 16. The current monitor 20 is built with an image information receiving device 22 and an image recognition processing device 21. The image information receiving device 22 is used to receive the image information captured by the holographic instant scanner 15, and the image recognition processing device analyzes and processes it, and displays the extracted data through a liquid crystal display screen 12 provided on the outer surface of the horizontal plate 11.

[0042] As a preferred solution of this embodiment, the push rod 13 is made of any one of thermoplastic polyurethane, thermosetting polyurethane, thermoplastic polyolefin plastic or thermoplastic polyester plastic.

[0043] As a preferred solution of this embodiment, the buffer ball 14 is made of any one of polystyrene foam plastic, polyethylene foam plastic or polyurethane foam plastic.

[0044] Working principle: When the present invention is used, first insert both positioning rods 1 into the soil within the selected reference plane until the depth limit plate 2 fits the soil surface. Then open the first sealing port 1006 and the second sealing port 1007, and add water to the U-shaped tube 10 from any one of them, and the amount of water should be such that both sides reach the vicinity of the scale line indication 5. It is easier to observe if there is colored water. Read the water level readings at the first scale line 1004 and the second scale line 1005, and adjust the telescopic rod 1 8 or the telescopic rod 2 9 by operating the control keyboard 7 so that the water level readings at the first scale line 1004 and the second scale line 1005 are consistent, and the horizontal plate 11 is in a horizontal state.

[0045] To ensure that the permanent magnet 18 can be triggered to move, the telescopic rod 1 8 and the telescopic rod 2 9 can be adjusted to extend to the same length according to the needs, so as to ensure that all the buffer balls 14 are in contact with the ground at the reference plane, and then the telescopic rod continues to push a certain length, which should not be too long, preferably half the length of the wire coil 17. At this time, the push rod 13 will push the permanent magnet 18 to move in the movable groove 19. When the permanent magnet 18 moves, the wire coil 17 cuts the magnetic flux lines of the permanent magnet 18. Since the two ends of the wire coil 17 are connected to the ammeter 16 to form a closed path, an induced current will be generated at this time. The magnitude of the current will be displayed on the ammeter 16, recorded by the current monitor 20 and displayed on the LCD screen 12.

[0046] Since the magnitude of the current in Faraday's law of electromagnetic induction is affected by factors such as the speed of wire cutting, the speed direction of wire cutting, the strength of the permanent magnet 18, the number of turns of the wire cutting coil 17, and the effective length of the wire cutting, in the present invention, the speed direction of wire cutting is fixed, the strength of the permanent magnet 18 and the effective length of the wire cutting are also the same, and the speed of wire cutting is equal to the speed of extension of the telescopic rod 1 8 and the telescopic rod 2 9, so the speed of movement of all permanent magnets 18 is the same, that is, the speed of wire cutting is the same. Therefore, the factor affecting the magnitude of the current can only be the number of turns of the wire cutting coil 17, and the distance that the push rod 13 pushes the permanent magnet 18 to move is positively correlated with the number of turns of the wire cutting coil 17, so the magnitude of the current is essentially a feedback of the moving distance of the permanent magnet 18, and the difference in the moving distance of the permanent magnet 18 at different positions is the height difference of the corresponding position of the reference surface.

[0047] Taking the minimum current point as the standard, the current at other locations exceeding this point reflects the distance that the location is higher than the minimum current point. By calculating the difference between the current at each location and the minimum current point, as well as the positive correlation coefficient between the current size and the active distance of the permanent magnet 18, the height of each location above the minimum current point can be calculated. When drilling and sampling in the later stage, this data can be used to correct the drilling depth, thereby ensuring the accuracy of the survey.

[0048] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
