Description

This is necessary for quality acceptance and assessment. The current main measurement method involves various combinations of tools such as theodolites, large measuring tapes, rulers, and plumb bobs.

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] On the one hand, such as Figure 1 As shown, this utility model embodiment provides an intelligent digital tank measuring instrument, including: a laser measuring instrument 1, a connecting component 2, a pan-tilt unit 3, a telescopic rod 4, and a tripod 5;

[0052] The bottom of the laser measuring instrument 1 is connected to the upper end of the connecting component 2;

[0053] The lower end of the connecting component 2 is connected to the upper end of the gimbal 3;

[0054] The lower end of the gimbal 3 is connected to the upper end of the telescopic rod 4;

[0055] The lower end of the telescopic rod 4 is connected to the upper end of the tripod 5.

[0056] In some embodiments, the tripod 5 provides stable support for the entire intelligent digital tank measuring instrument. The telescopic pole 4 on the tripod can adjust the height of the laser measuring instrument 1, thus eliminating the need for personnel to hold the measuring instrument and climb to measure. When personnel hold the measuring instrument and climb to measure, they need to manually ensure the stability of the measuring instrument. Personnel themselves may be unstable while climbing, making it difficult to obtain high-precision measurement results manually. Furthermore, temporary scaffolding often poses safety hazards for personnel climbing to heights. The pan-tilt head 3 connected to the telescopic pole 4 can adjust the horizontal and vertical orientation of the laser measuring instrument 1. The connecting component 2 is used to mount the laser measuring instrument 1 on the pan-tilt head. The connecting component and the laser measuring instrument can be connected by snaps or threads, and the connecting component and the pan-tilt head can be connected by snaps or threads.

[0057] The present invention has the following technical effects: The present invention combines a laser measuring instrument, a connecting component, a pan-tilt unit, a telescopic rod, and a tripod to form an intelligent digital tank measuring instrument, which is used to measure the geometric dimensions of various large tank containers. It eliminates the need for personnel to climb to heights for measurement, and solves the problems of difficult on-site measurement of various large tank containers, high personnel safety risks, and limited reading accuracy.

[0058] Furthermore, a camera 6 is provided on the laser measuring instrument 1;

[0059] The lens of the camera 6 is aligned with the laser emission port of the laser measuring instrument 1.

[0060] In some embodiments, a camera 6 is installed on the laser measuring instrument 1, and both face the same direction. Through the camera 6, the operator can view the position of the irradiation point of the laser measuring instrument 1 on the ground or the bottom of the tank via monitoring equipment such as a data terminal connected to the camera, thus eliminating the need to climb to a height to confirm the accuracy of the irradiation position of the laser measuring instrument 1. Figure 1 As shown, camera 6 can be embedded inside laser measuring instrument 1 or, as shown, in other cases. Figure 2 As shown, it is fixedly connected to the outer surface of the laser measuring instrument 1.

[0061] Furthermore, the laser measuring instrument 1 includes: a laser measuring instrument controller, a laser measuring head, a Bluetooth transmission module, an tilt sensor, a first Wi-Fi communication module, a first Beidou or GPS positioning module, and a display screen;

[0062] The laser measuring instrument controller is electrically connected to the laser measuring head, the Bluetooth transmission module, the tilt sensor, the first Wi-Fi communication module, the first Beidou or GPS positioning module, and the display screen.

[0063] In some embodiments, the laser measuring instrument controller includes, but is not limited to, a microprocessor or DSP processing chip. The laser measuring instrument controller controls the laser measuring head to emit lasers, collects tilt sensor data, and measures distance and tilt angle, etc. The current positioning is obtained through the first Beidou or GPS positioning module, and the measurement data is sent to the data terminal device through the first Wi-Fi communication module or Bluetooth transmission module. The measurement data is displayed on the screen. The laser measuring instrument 1 also includes multiple buttons for setting the working mode and parameters of the laser measuring instrument 1.

[0064] Furthermore, such as Figure 1 As shown, the gimbal 3 includes: a base 31, a horizontal rotation mechanism 32, a vertical rotation mechanism 33, a second Beidou or GPS positioning module, a second Wi-Fi communication module, an X-level glass bulb, and a Y-level glass bulb;

[0065] The horizontal rotation mechanism 32 is disposed on the base 31. The horizontal rotation mechanism 32 includes a horizontal drive motor, a horizontal transmission assembly, and a horizontal rotation shaft. The horizontal drive motor is connected to the horizontal rotation shaft through the horizontal transmission assembly, and drives the horizontal rotation shaft to rotate 360° in the horizontal direction.

[0066] The vertical rotation mechanism 33 is connected to the horizontal rotation axis. The vertical rotation mechanism 33 includes a vertical drive motor, a vertical transmission assembly, and a vertical rotation axis. The vertical drive motor is connected to the vertical rotation axis through the vertical transmission assembly and drives the vertical rotation axis to rotate in the vertical direction.

[0067] The second Beidou or GPS positioning module and the second Wi-Fi communication module are installed inside the base;

[0068] The X-level bulb and the Y-level bulb are mounted on the horizontal surface of the horizontal rotation mechanism 32 and are perpendicular to each other; they can be observed and adjusted during low-altitude measurements to keep the horizontal rotation mechanism 32 in a horizontal state.

[0069] The lower end of the connecting component 2 is connected to the vertical rotation mechanism 33.

[0070] Rotation in the vertical plane is achieved by the vertical rotation mechanism 33, and rotation in the horizontal plane is achieved by the horizontal rotation mechanism 32. By combining the rotation of the vertical rotation mechanism 33 and the horizontal rotation mechanism 32, the laser measuring instrument 1 can perform irradiation measurement at any position in three-dimensional space inside the tank.

[0071] Furthermore, such as Figure 1 As shown, the telescopic rod 4 includes: a first sleeve 41, a vertical rod 42 disposed inside the first sleeve, a rack 43 disposed on the surface of the vertical rod 42, a vertical rod drive motor 44 disposed on the outer surface of the first sleeve 41, and a first locking knob 45.

[0072] The upright 42 is sleeved inside the first sleeve 41 and is slidably connected to the first sleeve 41 in the longitudinal direction.

[0073] The shaft of the pole drive motor 44 is equipped with a gear that meshes with the rack 43.

[0074] The first locking knob 45 is threadedly engaged with the first sleeve 41, and passes through the outside of the first sleeve 41 into the inside, pressing against the surface of the upright 42.

[0075] In some embodiments, the rack 43 provided on the surface of the upright 42 can be a rack structure directly machined onto the surface of the upright 42, i.e., the rack 43 is fixed to the upright 42 as an integral part, or it can be a separately machined rack fixedly connected to the outer surface of the upright 42. The connection method includes, but is not limited to, welding or threaded connection. The first sleeve 41 is used to restrict the upright 42 from sliding up and down axially; the upright 42 is driven to slide up and down by the forward or reverse rotation of the upright drive motor 44; when the desired position is reached, the upright 42 can be stably positioned in the desired position by tightening the first locking knob 45 to hold the upright 42 against the surface. During the sliding of the upright 42, the first locking knob 45 is loosened so that the first locking knob 45 does not press against the surface of the upright 42, thereby allowing the upright 42 to slide up and down. The pole drive motor 44 drives the rack 43 to move the pan-tilt unit up and down via gear transmission (remote / manual pole drive motor 44). When the pole drive motor stops moving at the target measurement height or when the laser measuring instrument 1 is not needed at low altitudes, the first locking knob 45 is pressed against the surface of the pole 42. When assembling and machining the outer diameter of the pole 42 and the inner diameter of the first sleeve 41, their dimensions must match, and the gap cannot be too large. At the same time, the matching of the outer edge dimension of the rack 43 and the inner diameter of the first sleeve 41 must also be considered. Preferably, two electromechanical limit switches are added to the upper and lower ends of the rack 43. The electrical signals of the limit switches are fed back to the pole drive motor 44, so that the motor stops rotating when it reaches the extreme positions at the upper and lower ends of the rack. Because high-altitude measurements can only be operated by remote control (reading the height, horizontal angle and vertical angle displayed by the laser measuring instrument 1, and the image from the camera).

[0076] Furthermore, such as Figure 1 As shown, the tripod 5 includes:

[0077] The second sleeve 51, the disc 52, the three telescopic support rods 53, the three support sleeves 54, and the second locking knob 55;

[0078] The second sleeve 51 is vertically disposed on the upper surface of the disk 52, and the second sleeve 51 is coaxial with the disk 52;

[0079] The three telescopic support rods 53 are connected to the lower surface of the disc 52 to form a tripod support structure;

[0080] The three support sleeves 54 are respectively fitted onto the lower ends of the three telescopic support rods 53;

[0081] The first sleeve 41 is fitted inside the second sleeve 51;

[0082] The second locking knob 55 is threadedly engaged with the second sleeve 51, and passes through the outside of the second sleeve 51 to the inside, pressing against the surface of the first sleeve 41.

[0083] Furthermore, such as Figure 1 As shown, the support sleeve 54 includes: a first cylindrical section 541 and a tip bottom 542.

[0084] In some embodiments, the first cylindrical section 541 is sleeved on the end of the support rod 53, and the bottom of the tip 542 is a tip, which can provide more stable support on a rough surface.

[0085] Furthermore, such as Figure 3 As shown, the support sleeve 54 includes: a second cylindrical section 543, a rounded bottom 544, and an elastic pad 545 sleeved on the outside of the rounded bottom 544.

[0086] In some embodiments, the second cylindrical section 543 is sleeved on the end of the outrigger 53. The bottom of the rounded-head bottom 544 is rounded and installed inside the elastic pad 545 to avoid puncturing the elastic pad 545. The elastic pad 545 contacts a rough or smooth surface, which can increase the contact area and make it easier for the elastic material to form a vacuum fit with the contact surface, thereby providing more stable support on the rough or smooth surface. The rounded-head bottom 544 is a universal ball head shape. The rounded-head bottom 544 is about 2 / 3 spherical and is embedded in a metal spherical shell, just like the universal wheels under a freezer or the shoulder joint of a human body. The purpose is to ensure that the force at the end of the outrigger 53 is smoothly transmitted to the ground through the force-bearing surface, regardless of the spacing of the outrigger sleeves 54. The elastic pad 545 is preferably a non-slip rubber pad. When the tripod is placed on the bottom of a can with a metal plate, the three outriggers may slide unstably on the surface of the steel plate due to gravity, unlike three steel points inserted into the ground on the ground, which increases the friction between the outriggers and the steel plate.

[0087] Furthermore, the disc 52 is equipped with an XY glass level and a vertical instrument.

[0088] In some embodiments, the horizontal and vertical alignment of the tripod can be observed using an XY glass level and a vertical gauge to improve measurement accuracy.

[0089] Furthermore, it also includes: remote controls and data terminal equipment;

[0090] The gimbal 3 also includes: a gimbal controller and a first Bluetooth communication module;

[0091] The gimbal controller is electrically connected to the horizontal rotation mechanism 32, the vertical rotation mechanism 33, the second Beidou or GPS positioning module, the second Wi-Fi communication module, and the first Bluetooth communication module.

[0092] The telescopic rod 4 includes: a first sleeve 41, a vertical rod 42 disposed inside the first sleeve, a rack 43 disposed on the surface of the vertical rod 42, a vertical rod drive motor 44 disposed on the outer surface of the first sleeve 41, a first locking knob 45, a second Bluetooth communication module, and a telescopic rod controller.

[0093] The telescopic pole controller is electrically connected to the second Bluetooth communication module and the pole drive motor 44.

[0094] The laser measuring instrument 1 includes: a laser measuring instrument controller, a laser measuring head, a Bluetooth transmission module, an tilt sensor, a first Wi-Fi communication module, a first Beidou or GPS positioning module, and a display screen;

[0095] The remote control is wirelessly connected to the first Bluetooth communication module and the second Bluetooth communication module via Bluetooth signals.

[0096] A camera 6 is installed on the laser measuring instrument 1;

[0097] The lens of the camera 6 is aligned with the laser emission port of the laser measuring instrument 1;

[0098] The data terminal device is connected to the second Wi-Fi communication module, the first Wi-Fi communication module, and the camera's wireless signal.

[0099] In some embodiments, a remote control can be connected to a first Bluetooth communication module and a second Bluetooth communication module to remotely control the gimbal 3 and telescopic rod 4 from the ground or the bottom of the tank, thereby remotely controlling the position and attitude of the laser measuring instrument 1. Through a data terminal device connected to the second Wi-Fi communication module, the first Wi-Fi communication module, and the camera's wireless signal, the data terminal device can receive images from the camera. Personnel can observe from the ground or the bottom of the tank whether the illumination point of the laser measuring instrument 1 is correct. The data terminal device can also receive laser measurement data from the laser measuring instrument 1, including but not limited to distance and angle, and generate data tables through an APP pre-installed on the data terminal device. It can also communicate with a remote server to submit the data tables, enabling remote monitoring. The data terminal device is used to upload the measurement data of the "intelligent digital tank measuring instrument" to a supporting computer server on the public internet. The remote control is used to rotate the horizontal rotation mechanism 32 of the gimbal 360° in the horizontal plane, rotate the vertical rotation mechanism 33 180° in the vertical plane, and drive the rack 43 up and down via the pole drive motor 44. The mobile app (including the remote control) is used by the laser measuring instrument 1 to collect, upload, and download all measurement data (length, angle, area, volume, etc.), BeiDou / GPS location, temperature, etc. (via Wi-Fi). Bluetooth can directly connect and exchange data wirelessly with the remote control, mobile app, and laser measuring instrument 1.

[0100] The embodiments of the present invention have the following technical effects: by submitting data to a remote server through a data terminal device, construction or testing data is stored in the cloud for easy retrieval and re-verification in the future, which solves the technical problems of difficulty in tracking and querying measurement data in the later stage and difficulty in reproducing the original construction data after a major quality and safety accident.

[0101] The technical solutions of the present invention will be described in detail below with reference to specific application examples. For technical details not described in the implementation process, please refer to the relevant descriptions above.

[0102] With the widespread use of oil and LNG (liquefied natural gas), the manufacture of various large storage tanks has become increasingly important. Therefore, the quality indicators of tank measurement data need to be convenient and accurate, making this measuring instrument more promising in terms of usability and widespread application. This utility model provides an intelligent digital tank measuring instrument, specifically a digital large tank diameter (internal) measuring instrument. It is used in engineering construction quality measurement, oil and petrochemical refining engineering construction, and other fields related to the construction of storage tanks (containers). The measuring personnel only need to stand on the tank floor to quickly take measurement readings. It uses a digital display, has digital module storage and automatic calculation functions, and can be upgraded to upload data to a WiFi network.

[0103] This utility model embodiment solves at least the following problems: measuring the straight-line distance (radius of curvature), roundness (ellipticity), verticality of the tank, vertical distance between any two points on the tank wall generatrix, the angle between the measuring line and the horizontal (angle between the measuring line and the vertical), the horizontal angle between two measuring lines, and the measurement of geometric dimensions and deviations required in containers such as GB / T 50128 "Construction Specification for Vertical Cylindrical Steel Welded Storage Tanks", as well as the automatic calculation of the geometric measurement dimensions of the tank wall.

[0104] The inventors discovered that, according to the technical quality requirements for geometric dimensions in storage tank manufacturing standards, the geometry of the storage tank needs to be measured during construction and final acceptance to determine whether the equipment meets the design and national standard requirements. Generally, because the diameter and height of the equipment are very large, the inspection requires obtaining the geometric dimensions and manufacturing deviations of the equipment on-site immediately according to the standard requirements and filling in forms. This brings great difficulty to the measurement of tall equipment. In order to overcome this difficulty in on-site measurement, this digital storage tank laser measuring instrument was invented and the measurement data is uploaded to the network to remotely control the equipment acceptance process.

[0105] The digital tank measuring instrument includes: a laser measuring instrument, a pan-tilt unit, a rack and pinion motor lifting mechanism (telescopic rod) and tripod, a digital processing system, and a Wi-Fi network system.

[0106] Laser measuring instrument: This is the core of the measurement system for reading the data to be measured. It can measure and read straight-line distance (radius of curvature), roundness (ellipticity), verticality of the storage tank, vertical distance between any two points on the generatrix of the tank wall, angle between the measuring line and the horizontal of the earth (angle between the measuring line and the elevation of the earth), horizontal angle between two measuring lines, and calculate the irregular volume of the actual storage tank (estimation method, rotational body calculation method, block calculation method, integration method, etc.).

[0107] Intelligent tracking gimbal (gimbal): Specifically including but not limited to: can be equipped with a 360° AI intelligent tracking gimbal, which adopts a three-dimensional gimbal, and can be adjusted or rotated along three different axes of X, Y and Z, so that the target object can reach different angles and orientations.

[0108] Connection component: The laser measuring instrument and the pan-tilt unit are connected by a connection component, which is equipped with a locking knob. This connection component is primarily used to drive the laser measuring instrument to perform various mechanical movements in three dimensions and circumference.

[0109] Rack and pinion motor lifting mechanism (telescopic rod) and tripod: The bottom of the measuring instrument is a remote-controlled automatic lifting tripod (a combination of rack and pinion motor lifting mechanism and tripod). The tripod supports the weight of the entire digital tank measuring instrument, keeping it horizontal or at a certain angle. The three tripods are telescopic, and the bottom is a needle-shaped ground fixing end (or a rubber fixing plate inside the tank), with a glass level and a vertical indicator on it. The upper part of the tripod is a motor-driven lifting mechanism (controlled by a Bluetooth remote control) and can also be manually cranked for lifting. The top of the tripod is a flat plate with mechanical components (bolted connection) for fixing the gimbal. The rack and pinion motor lifting mechanism and tripod combination includes, but is not limited to, an infrared extension lifting telescopic (or bamboo-joint) rod device.

[0110] Digital processing module (data terminal equipment): This module digitizes the length, angle, area, and volume values ​​read by the laser measuring head and automatically generates measurement result tables for export as electronic versions and for printing, including GPS / BeiDou geodetic positioning data. It also allows for Bluetooth connection and sharing between a mobile app and the laser measurement database. The digital processing module includes a GPS or BeiDou positioning module, a Bluetooth communication module, and a data processing module (including but not limited to a microprocessor MCU, DSP, and memory).

[0111] The Wi-Fi network system connects the measurement data generated by the digital processing module to the Internet platform using Wi-Fi technology. This allows the mobile app to upload the database of the tank manufacturing geometry data generated by laser measurement, along with GPS / BeiDou information such as the location and date of the tank measurement points, to the Internet platform server. This enables remote terminals to judge the acceptance quality of the tank equipment, as well as to facilitate future tank quality tracking and the digitization of as-built data.

[0112] For manual reading of measurement data, an upgraded board can be added to provide voice reporting, making it easier for engineers to manually record and read the data.

[0113] Laser measuring instrument: Primarily utilizing the principle of high-precision laser ranging, it is the core measuring component of the digital tank measuring instrument for reading data at measurement points. The laser measuring instrument can measure and read straight-line distances (e.g., radius of curvature), the vertical distance between any two points on the tank wall generatrix, and the angle between the measuring line and the horizontal ground. It can also measure and calculate roundness (or ellipticity), verticality, area, and volume of the tank. A camera is installed within the laser measuring instrument, with its lens aligned with the laser emission port, allowing observation of the laser measurement points on the tank wall. An inclination sensor is also included to measure the ground inclination angle (eliminating the need for a level). It can directly and automatically read the measured vertical line segments and horizontal distances. A Bluetooth module connects to a mobile phone, allowing data transmission to the phone and then uploading to a cloud server via Wi-Fi. Through high-precision laser point measurement and data reading, Bluetooth connectivity, and Wi-Fi transmission to the cloud, the instrument achieves the measurement values ​​required by standards and specifications, meeting the target values ​​for engineering acceptance and quality assessment, thus realizing the invention's purpose.

[0114] The laser measuring instrument features Bluetooth connectivity for mobile phones, a built-in Wi-Fi module, BeiDou / GPS positioning, a camera, and an inclination sensor to measure the ground's tilt and elevation angles. It can automatically read the measured vertical line segments, horizontal distances, and angles. Data can be uploaded to a mobile phone via Bluetooth or Wi-Fi. When measuring inside a metal storage tank, the electrostatic shielding effect allows for Bluetooth connectivity, or a dedicated telecommunications signal adapter can be purchased to connect to the tank's manhole for Wi-Fi connectivity.

[0115] Intelligent Tracking Gimbal: To ensure the measurement effect and accuracy of the laser measuring head, an intelligent tracking gimbal is installed below it, including but not limited to a 360° AI intelligent tracking gimbal. The gimbal can rotate 360° horizontally and 180° vertically. It is equipped with a Beidou / GPS positioning device and uploads the geographical location of the measuring equipment to the cloud via Wi-Fi. The main function of the intelligent tracking gimbal is to drive the laser measuring instrument to perform mechanical movements in various directions and positions.

[0116] The intelligent tracking gimbal can rotate 360° horizontally and 180° vertically. It is equipped with a Beidou / GPS positioning device and WIFI to upload positioning data to the cloud. It also includes an XY level bulb for adjusting the gimbal's levelness.

[0117] Connecting component (mainly made of metal): A connecting component is installed between the laser measuring instrument and the intelligent tracking gimbal, and a locking knob is attached to the connecting component. It is mainly through this connecting component that the intelligent tracking gimbal drives the laser measuring instrument to perform various three-dimensional and circumferential mechanical movements.

[0118] Rack and pinion motor lifting mechanism (mainly manufactured from high-strength aluminum alloy or high-strength carbon fiber and an electric motor): Connected below the intelligent tracking gimbal is the rack and pinion motor lifting mechanism. This mechanism features a climbing track and a lifting motor, with remote control controlling the motor's direction and speed. This allows the laser measuring head to be lifted along the track column, vertically to a high position inside the tank and then vertically retrieved. The primary purpose of the rack and pinion motor lifting mechanism is to enable the laser measuring instrument to accurately and smoothly reach various heights within the tank through vertical lifting. Limit switches at both ends of the rack protect against broken teeth and motor overload. A camera is included to monitor the laser points projected onto the tank wall and the construction quality at higher points on the tank wall (e.g., welds, bumps, etc.).

[0119] A rack is fixed to the outer surface of the upright as a crawling track along the upright. The outer diameter of the rack upright component is smaller than the inner diameter of the outer sleeve, allowing the rack upright to move up and down within the metal sleeve. The rack upright component is surrounded by a sleeve, and a motor is fixed to the outer surface of the sleeve via a motor bracket. A continuously variable speed motor shaft is equipped with a gear that drives the gear to rotate, allowing for stepless micro-motion. The motor is controlled by a remote control; by changing the polarity of the motor's power supply, it can rotate in both directions to move the upright up and down. The gear and rack on the motor shaft transmit power through gear meshing. The rotation of the motor gear drives the rack upright to move up and down, and allows for fine-tuning, thereby causing the pan-tilt unit and laser measuring instrument to move vertically up and down inside the tank. When the measuring instrument reaches the height of the measuring point on the pipe wall, it emits a laser to take a measurement reading, thus achieving the purpose of the measurement invention.

[0120] Telescopic (or bamboo-joint) tripod assembly (mainly manufactured from high-strength aluminum alloy or high-strength carbon fiber): Connected to the rack and pinion motor lifting mechanism is a telescopic (or bamboo-joint) tripod assembly. The mechanism vertically above the disc is a tubular structure, with the tripod connected below. The disc, which connects the upper and lower parts, is horizontal and has an XY-axis bidirectional level glass tube embedded in it for adjusting the disc's level. The tripod connecting the disc is a modular structure, placed on the ground or at the bottom of the tank. When the lower legs of the tripod are placed on the ground, the lowest point is a metal point (pressed into the ground manually by foot). When the tank bottom is concrete, it can be placed on a concrete foundation. When placed on the metal steel plate at the bottom of the tank, the lowest point has a non-slip rubber pad to increase friction with the tank bottom. The main function of the entire tripod assembly is to stabilize the measuring instrument and ensure it stands upright on the bottom of the tank, supporting the weight of the entire measuring equipment and preventing tilting.

[0121] For measuring the geometric dimensions of storage tanks, on-site measurements are typically performed manually by quality inspectors, technicians, and engineers using handheld testing tools. This is especially true for projects with limited investment and a small number of simple equipment items. Manual measurement makes quality inspection and data collection time-consuming, labor-intensive, costly, inefficient, and results in long data processing cycles. Furthermore, measurements of storage tanks at heights can pose significant personal safety risks, and taking photographic evidence manually is extremely difficult.

[0122] By using a laser measuring instrument, the problem of measuring the radius of curvature, roundness (ellipticity), verticality of the tank wall, geometric irregularity, area, and volume of storage tanks required by standards and specifications for oil, refining, and chemical industries has been solved. In particular, for the difficulty of measuring the tank wall at height, it eliminates the safety risks of working at height and the cost and time of erecting scaffolding, thus speeding up the measurement process and reducing manufacturing measurement costs.

[0123] The intelligent tracking gimbal design ensures the measurement effect and accuracy of the laser measuring instrument, enabling the measurement and data acquisition of target points at any location in three-dimensional space along the X, Y, and Z axes, thus providing conditions for manual ground-based remote control operation.

[0124] By using the crawling track component and lifting motor of the lifting mechanism, the problem of measuring at high altitudes inside the tank with the laser measuring head perpendicular to the ground has been solved. In particular, for large ultra-high storage tank equipment, it has solved the problem of measuring numerical values ​​on the tank wall at high altitudes and the difficulty of continuously measuring tank wall morphology at different heights has been solved.

[0125] The telescopic tripod device solves the problems of equipment instability and easy tilting, ensuring the verticality of the measuring instrument and eliminating the problem of slippage between the equipment and the tank bottom.

[0126] The addition of cameras solves the problem of real-time monitoring and video recording of defects exceeding standards in storage tanks. The addition of a Beidou / GPS positioning device enables location recording and tracking of measured values. The addition of Bluetooth connectivity eliminates the need for manual reading of laser measuring instrument screen values, especially at high altitudes, preventing potential injuries. The addition of a Wi-Fi module and mobile app allows for manual reading and extraction of measurement data via smartphone and internet, particularly for remote control of storage tank construction acceptance and quality assessment, as well as evaluation of quality and progress. The increased digitization and networking of this equipment facilitates the real-time generation of measurement reports in both text and graphical formats, laying the foundation for future IoT and AI-powered intelligent management of construction sites.

[0127] The following is an example of the method (usage method) for measuring the mass values ​​specified in the standard specifications inside the storage tank:

[0128] 1. Installation: First, based on the radius R and tank wall height H of the tank design drawings, select the corresponding distance range and height of the laser measuring instrument. If the tank bottom is made of steel plate, the tripod should have a non-slip rubber base. This determines the appropriate model of the measuring instrument series to use.

[0129] 2. Initial calibration of the laser measuring instrument: According to the diameter of the circular tank on the design drawings, find the center of the bottom of the circular tank (the construction party usually marks the center position on the bottom of the tank during the construction of the tank). Assemble the digital tank measuring instrument from the center and ensure that it is positioned at the horizontal 0-degree line by (1) the level on the tripod disc, (2) the three-dimensional rotation of the intelligent tracking gimbal, and (3) the laser measuring instrument is installed at 0 degrees. The angle between the laser measuring instrument and the horizontal plane displayed on its screen is 0 degrees. Adjust the horizontality and verticality of the measuring instrument to ensure that the laser measuring instrument is aligned with the horizontal plane. To ensure the horizontality and overall verticality during the vertical lifting and lowering of the motor, adjust the horizontal reading of the top laser measuring instrument. When the laser measuring instrument display shows a distance of 0, the position of the laser measuring instrument's 0 distance should be vertically projected to the center point of the bottom of the tank (the method for setting the 0 distance point is usually explained in detail in the instruction manual of the selected laser measuring instrument). Set the center axis of the connecting component 2 as the laser measuring instrument's 0 distance reading. The accuracy of the laser measuring instrument's initial 0 distance point coinciding with the center of the bottom of the tank (i.e., on the vertical line from the ground at the center point) is very important. Verification and debugging method to ensure the center of the bottom of the tank is the laser measuring instrument's 0 distance point: Use the gravity (line) pointing towards the center of the earth (the gravity line is perpendicular to the ground, i.e., the bottom of the tank). Procedure: Move the tripod so that the vertical line from the center of the lower surface of the disc 52 falls onto the bottom circle of the tank (note that the disc surface should be leveled simultaneously using the level on the disc 52). A plumb line can be suspended at the center of the lower surface of disc 52 (i.e., along the axis of horizontal rotation of the tripod including the gimbal), connected by screws. Simply move the tripod so that the tip of the plumb line falls onto the center point. Using the center of the can's bottom as the center, draw a circle of arbitrary radius on the can's bottom with a pen or needle. Place a right-angled steel ruler or triangle vertically on the circle, ensuring the right-angled side of the ruler is perpendicular to the can's bottom. Rotate the gimbal 32 360 degrees and measure the horizontal distance to the perpendicular right-angled side. As long as the laser measuring instrument reading (circle radius) remains unchanged, a zero value on the laser measuring instrument indicates the can's bottom center is coincident. Alternatively, draw a circle from the can's bottom center, and draw XY-axis crosshairs. The intersection of the crosshairs is the center of the circle, and the crosshairs intersect the circle at four points. Use the laser measuring instrument to read the horizontal distance of the right-angled side at each of the four intersection points. Based on the readings, move the tripod. If all four readings are the same, the zero value on the laser measuring instrument indicates the can's bottom center is coincident. To find the center of the tank bottom: Use an ink line or wire to measure the distance between two points at the base of the tank bottom edge. Move the measuring points along the base edge. When the distance between the two points is at its maximum, the measured value is the actual diameter of the tank. The intersection of the two diameters is the center of the circle.

[0130] The laser measuring instrument can be used according to the instruction manual. It can be operated via the buttons on the laser measuring instrument 1 or the buttons on the mobile APP (or the buttons on the remote control). Different manual buttons will display corresponding measurement values, such as: straight-line distance, the difference between two straight-line distances, the sum of two straight-line distances, the product of two straight-line distances, the quotient of two straight-line distances, the angle between the laser ray and the ground (elevation and depression), the perpendicular angle between the laser ray and the gravity line, the horizontal angle between two laser rays, the vertical angle between two laser rays, the result of trigonometric function calculations, area, volume, etc. The buttons on the remote control mainly control the movement of the pan-tilt unit 3 and the pole drive motor 44.

[0131] Before measurement, the mobile phone and laser measuring instrument are wirelessly paired via Bluetooth. All measurement values ​​from the laser measuring instrument can be controlled via a mobile app (soft key press operation). Measurement values ​​displayed on the laser measuring instrument's screen can be read from the phone, and the app automatically generates record tables and reports. The mobile app can also connect directly to a laptop computer. Measurements (including measurement time and BeiDou / GPS location) can be uploaded to the Internet via the mobile app.

[0132] 3. The method and steps for directly measuring the radius of the storage tank from the center of the horizontal circle inside the tank:

[0133] The first step is to determine a certain height of the tank and a certain location on the tank wall to be measured, which will be the target point for data extraction (temporarily referred to as point M on the inner side of the tank wall).

[0134] The second step involves rotating the connecting component and securing the locking knob to bring the laser measuring instrument to a horizontal position, thus vertically fixing and locking the connecting component and the laser measuring instrument. Then, the connecting component is connected to the universal joint of the intelligent tracking pan-tilt unit, ensuring that the connecting component and the intelligent tracking pan-tilt unit are vertically fixed and locked (the pan-tilt unit is in a horizontal position).

[0135] The laser measuring instrument can be used according to the instruction manual. By pressing different manual buttons, you can read the corresponding measurement values ​​from the display screen, such as: straight-line distance, the difference between two straight-line distances, the sum of two straight-line distances, the product of two straight-line distances, the quotient of two straight-line distances, the angle between the laser ray and the ground (elevation and depression), the perpendicular angle between the laser ray and the gravity line, the horizontal angle between two laser rays, the vertical angle between two laser rays, the result of trigonometric function calculations, area, volume, and other values.

[0136] Before measurement, the mobile phone and laser measuring instrument are wirelessly paired via Bluetooth. All measurement values ​​from the laser measuring instrument can be controlled via a mobile app (soft key press operation). Measurement values ​​displayed on the laser measuring instrument's screen can be read from the phone, and the app automatically generates record tables and reports. The mobile app can also connect directly to a laptop computer. Measurements (including measurement time and BeiDou / GPS location) can be uploaded to the Internet via the mobile app.

[0137] Before measurement, adjust the 0-distance reading point of laser instrument 1; adjust the rotation axis of the tripod to fall on the center of the circle. Make sure that the 0-distance reading point of laser instrument 1 and the rotation axis of the tripod are both vertically projected onto the center of the bottom of the tank.

[0138] The third step is to adjust the XYZ axes of freedom on the intelligent tracking gimbal, aligning the three axis scale lines with the 0-degree line to ensure the intelligent tracking gimbal is in a horizontal position.

[0139] The fourth step is to adjust the height of the three telescopic legs of the tripod of the telescopic tripod assembly to ensure that the two bubble levels X and Y on the tripod disc are in a horizontal position, thus ensuring that the disc is in a horizontal state.

[0140] Fifth, adjust the motor movement of the rack and pinion motor lifting mechanism and the relative height of the main rod guide rail (when the motor gear rotates forward and backward, the main rod inside the sleeve rises and falls accordingly, thus changing the height), so that the laser measuring instrument initially reaches the target position point M on the tank wall to be measured.

[0141] The sixth step involves using the remote control of the motor on the rack and pinion motor lifting mechanism (or manually adjusting the motor by turning the knob when the ground is low). By fine-tuning the motor with the remote control, the laser point of the laser measuring instrument coincides with the target point M, indicating that the laser measuring instrument has accurately reached the height H inside the tank to be measured.

[0142] Step 7: Use the remote control to rotate the intelligent tracking gimbal along the horizontal plane, which in turn rotates the laser measuring instrument horizontally. This causes the laser point on the tank wall to rotate and illuminate the target point M on the inside of the tank wall, thereby measuring the distance (inner radius R) from the horizontal center of the storage tank to the inner surface of the tank wall.

[0143] Based on step seven, by measuring different differences in radius R within the same horizontal plane, the tank's concavity, angularity, roundness, and other indicators are obtained. On the same generatrix of the tank wall, based on different heights H in step six, the tank's angularity, verticality, and other indicators are obtained by measuring different radii R at the corresponding points.

[0144] Step 8: For measurement heights close to the ground, the laser measuring instrument, intelligent tracking gimbal, and rack and pinion motor lifting mechanism can be manually operated to directly measure and read values. For high-altitude measurements where direct manual operation is not possible, a remote control can be used to rotate the intelligent tracking gimbal in three-dimensional space, and to rapidly raise, lower, and fine-tune the motor lifting mechanism along the Z-axis. This causes the laser measuring instrument to move vertically and circumferentially within the tank, similar to a hospital CT scan. A horizontal section can be created at any height within the tank, and laser measurements can be performed on any point on the tank wall within this horizontal section to read the data.

[0145] The ninth step involves collecting and organizing data, comparing it with design drawings and national standards and specifications, to obtain the required tank measurement results (radius of curvature, roundness (ellipticity), tank wall verticality, geometric irregularity, etc.), conducting tank quality process control and acceptance evaluation, and ultimately achieving the manufacturing goal of Internet of Things and remote network control.

[0146] 4. The method and steps for measuring tank wall parameters at any height on the vertical line from the center of the tank:

[0147] All nine steps in step 3 above are the same except for step 5. The operation of the embodiment is as follows:

[0148] Using the remote control of the intelligent tracking gimbal, by rotating the intelligent tracking gimbal vertically, the laser measuring instrument can be rotated within the vertical plane of the earth, so that the laser measuring instrument and the horizontal plane form a certain angle of elevation (or downward angle). By operating the laser measuring instrument through a mobile APP, you can read the laser beam distance (i.e., the hypotenuse length of the right triangle perpendicular to the ground), the length of the horizontal line (or radius R) (i.e., the length of the straight side of the right triangle perpendicular to the ground), the difference between the lengths of the two lines, the angle between any two points on any generatrix of the tank wall and the position point of the laser measuring instrument on the vertical plane, and the angle between any two points on the horizontal circular surface of the tank wall and the position point of the laser measuring instrument on the horizontal plane.

[0149] Within the same horizontal plane, rotating the intelligent tracking pan-tilt unit 180 degrees reverses the laser measuring instrument by 180 degrees. The sum of the lengths of the two measured lines is the diameter D of the storage tank (i.e., the value of 2R). By operating the intelligent tracking pan-tilt unit, the laser measuring instrument measures the distance perpendicularly above the top of the tank, and then measures the distance perpendicularly below the bottom of the tank by rotating it 180 degrees. The sum of these two values ​​is the height H of the storage tank. By pressing the button on the laser measuring instrument twice, the instrument automatically displays the sum of the two values ​​(the diameter D and the height H of the storage tank). By calculating the difference in the diameter D and the difference in the height H at different measurement points, the diameter deviation and height deviation of the storage tank at different locations are obtained.

[0150] When measuring using a remote-controlled rotating intelligent tracking gimbal, pay attention to the spatial position of the distance reading on the laser measuring head display screen inside the tank (i.e., the initial position 0 setting).

[0151] 5. Measure the tank wall parameters at any location inside the storage tank (including locations other than the center):

[0152] Based on the functions of the laser measuring head, the laser measuring instrument can automatically measure straight-line distances, the difference between two straight-line distances, the sum of two straight-line distances, the product of two straight-line distances, the quotient of two straight-line distances, the angle between the laser ray and the ground (elevation and depression angles), the perpendicular angle between the laser ray and the gravity line, the horizontal angle between two laser rays, the vertical angle between two laser rays, the result of trigonometric function calculations, area, volume, and other numerical values. Through the 360° AI intelligent tracking gimbal of component 3, which can rotate arbitrarily along the XYZ axes in three-dimensional space, and by operating them in conjunction with each other, and through Bluetooth connection, APP software, Wi-Fi network technology, Beidou / GPS positioning, and other functions, comprehensive numerical measurement and control of the storage tank can be achieved.

[0153] Laser measuring heads (laser rangefinders) typically include the following functions: single length measurement, area measurement, volume measurement, single Pythagorean theorem measurement (length of the perpendicular side of a right triangle), double Pythagorean I measurement (length of two halves of the right triangle), double Pythagorean II measurement (length of a segment on a right triangle, length of two points on the right triangle), triangle area measurement (area enclosed by the three sides of a general triangle), trapezoid measurement (length of the hypotenuse of a right trapezoid), automatic horizontal measurement (length of the horizontal base of a right triangle), automatic vertical measurement (length of the opposite side of the included angle of a general triangle), point-to-point measurement (measuring two sides of a general triangle to determine the length of the third side), and countdown measurement (automatic delay measurement).
