Description

Technical Field

[0001] This invention relates to the field of underground engineering mud testing technology, and in particular to an in-situ sampling and testing device for engineering mud. Background Technology

[0002] In underground engineering construction, drilling mud plays a crucial role in stabilizing borehole walls, carrying drill cuttings, cooling drilling tools, and balancing formation pressure. Stable mud performance is essential for ensuring construction safety and controlling project quality. Therefore, timely, accurate, and convenient performance testing of drilling mud at the construction site is of paramount importance.

[0003] Currently, the traditional "manual sampling-laboratory analysis" model is commonly used for mud performance testing at underground engineering sites. This model requires operators to physically go to mud pits, circulation trenches, or borehole openings to manually collect mud samples using simple tools. The samples are then transported to a laboratory or fixed testing point far from the work surface for instrumental analysis. However, this traditional method has revealed a series of significant shortcomings in engineering practice, making it difficult to meet the requirements of modern, efficient, intelligent, and safe construction. Firstly, it cannot achieve in-situ testing; existing technology lacks devices capable of directly and in-situ integrated sampling and real-time testing of mud. Summary of the Invention

[0004] The main objective of this invention is to provide an in-situ sampling and testing device for engineering mud, which solves the problem that traditional testing methods cannot implement in-situ sampling and real-time testing.

[0005] This application provides an in-situ sampling and testing device for engineering mud, comprising:

[0006] Base

[0008] A telescopic upright is mounted on the base and is capable of rotating relative to the base;

[0009] A telescopic crossbar is installed on the telescopic upright and can extend and retract laterally relative to the telescopic upright.

[0010] The sampling mechanism includes a winch, a measuring wheel, a slurry collection bucket, and a sensor. The winch drum is located at the top of the telescopic pole. The winch wire rope is wound around the measuring wheel and connected to the slurry collection bucket. The measuring wheel is located on the telescopic crossbar on the side away from the telescopic pole. The sensor is located inside the slurry collection bucket and is used to detect the slurry inside the bucket.

[0011] According to an embodiment of this application, the sampling mechanism further includes a tensioning mechanism, which is disposed on the telescopic crossbar between the meter wheel and the drum, and abuts against the wire rope.

[0029] This application provides an in-situ sampling and testing device for engineering mud, referring to... Figure 1 and Figure 2It includes a base, a traveling mechanism, a telescopic upright 15, a telescopic crossbar 10, and a sampling mechanism. The base is the basic structural component that supports and fixes all parts of the device, and serves as the installation benchmark for the entire device.

[0030] The traveling mechanism is located below the base. The traveling mechanism is a mechanical assembly that can drive the device to move in position, providing power and motion support for the movement of the device.

[0031] A telescopic pole 15 is mounted on the base and is rotatable relative to the base. The telescopic pole 15 is a rod-shaped structure that can extend and retract vertically and rotate around the base, used to adjust the vertical height and horizontal rotation angle of the sampling mechanism. The telescopic pole 15 can also be height-adjusted according to the operator's height. Exemplarily, it can be a hydraulic telescopic pole 15 (composed of an outer cylinder, an inner cylinder, and a hydraulic cylinder) or an electric screw telescopic pole 15 (driven by a screw, a nut, and a servo motor 19).

[0032] The telescopic crossbar 10 is mounted on the telescopic upright 15 and is capable of lateral extension and retraction relative to the telescopic upright 15. The telescopic crossbar 10 refers to a rod-like structure that can extend and retract in length along the horizontal direction, used to adjust the lateral position of the sampling mechanism in conjunction with the telescopic upright 15. Exemplarily, it can be a pneumatic telescopic crossbar 10 (driven by a cylinder, piston, and compressed air) or a manually operated helical telescopic crossbar 10 (composed of inner and outer rods and a helical locking structure).

[0033] In the applied engineering mud in-situ sampling and testing device, the simultaneous adjustment of the height of the telescopic upright 15 and the length of the telescopic crossbar 10 of the cantilever telescopic structure is essentially a two-dimensional adjustment combination of "vertical height + horizontal radius" to achieve a synergistic improvement in the spatial adaptability, operational flexibility and sampling accuracy of the sampling operation, which has significant advantages compared to adjusting either one alone.

[0034] When adjusting the pole height or cantilever length individually, the sampling coverage of the device is limited by the adjustment capability in a single dimension. However, combining the two enables "sampling coverage in three-dimensional space," precisely adapting to the diverse testing needs of underground engineering projects. It can handle complex terrain obstacles; underground engineering sites often contain obstacles such as pit edges, temporary access roads, construction machinery, and pipeline supports. The combination of the two allows for flexible avoidance of these obstacles.

[0035] Moreover, the stability of the sampling operation directly affects the accuracy of the test data (such as avoiding sample spillage caused by shaking of the slurry tank 12 and collision of the sensor 16). The coordinated adjustment of the two can optimize the operating posture of the device, balance the sampling range and structural stability, avoid the center of gravity imbalance caused by single adjustment, and reduce the shaking interference of the slurry sampling device.

[0036] The sampling mechanism includes a winch 9, a measuring wheel 11, a slurry collection bucket 12, and a sensor 16. The drum of the winch 9 is located at the top of the telescopic pole 15. The wire rope of the winch 9 is wound around the measuring wheel 11 and connected to the slurry collection bucket 12. The measuring wheel 11 is located on the telescopic crossbar 10 on the side away from the telescopic pole 15. The sensor 16 is located inside the slurry collection bucket 12 and is used to detect the mud in the slurry collection bucket 12.

[0037] In the automated engineering mud in-situ sampling and testing device of this patent, the core function of the meter wheel 11 is to accurately measure the lowering depth of the mud sampling bucket 12 and the sensor 16, providing key data support for the depth accuracy of mud in-situ sampling and testing.

[0038] The metering wheel 11 is installed on the cantilever telescopic structure and works in conjunction with the winch 9 and the motor. Its core function is to indirectly calculate the lowering depth of the slurry bucket 12 and the sensor 16 by recording the running distance of the equipment.

[0039] On the one hand, depth positioning is performed. During the sampling and testing process, the control system needs to set a specific mud detection depth according to engineering requirements (such as the mud layer position of different strata in a deep foundation pit). The meter wheel 11 records the length of the rope released by the winch 9 (or the linear distance of the mud sampling device descending) in real time and transmits the data to the control system to ensure that the mud sampling bucket 12 and the sensor 16 are accurately lowered to the preset depth, avoiding incorrect sampling and testing objects due to depth deviation (such as mistakenly sampling shallow mud instead of mud at the target depth).

[0040] On the other hand, safety protection can be implemented: the depth data recorded by the metering wheel 11 can be used as a basis for "safety limit". When the lowering distance reaches the preset "maximum safe depth" (such as to avoid the slurry sampling device from touching the bottom of the pit or obstacles), the control system can automatically stop the lowering action according to the signal of the metering wheel 11 to prevent equipment damage or sampling failure.

[0041] In the aforementioned in-situ sampling and testing device for engineering mud, the base provides stable support for the entire device, ensuring that all components are securely installed. The traveling mechanism enables the device to move autonomously, overcoming the limitations of a fixed position and adapting to the sampling needs of different construction sites. The combination of telescopic poles 15 and 15 allows for flexible adjustment of the spatial coordinates of the sampling bucket 12, enabling multi-directional and multi-angle sampling. The sampling mechanism integrates a winch 9, a metering wheel 11, and a sensor 16. The winch 9 controls the raising and lowering of the sampling bucket 12, while the metering wheel 11 precisely controls the sampling depth. Simultaneously, the sensor 16 can perform testing directly within the sampling bucket 12, eliminating the need for sample transfer, shortening the testing cycle, and improving testing efficiency.

[0042] In some embodiments, the sampling tank 12 is an integrated sampling tank 12, and the sampling tank 12 and the sensor 16 can perform sampling and detection simultaneously.

[0043] The sensor 16 can automatically detect mud performance indicators, and the signal is directly transmitted to the control system.

[0044] In some embodiments, refer to Figure 1 and Figure 2 The sampling mechanism also includes a tensioning mechanism, which is disposed on the telescopic crossbar 10 between the meter wheel 11 and the drum, and abuts against the wire rope.

[0045] A tensioning mechanism is a mechanical structure used to adjust the tension of a wire rope and prevent it from slackening, swaying, or deviating from a preset track. For example, it is a spring-type tensioning mechanism, consisting of a tension wheel, a spring, and a support. Tensioning is achieved by the spring force pushing the tension wheel to compress the wire rope.

[0046] The tensioning mechanism can eliminate the slack caused by changes in length and fluctuations in force during the winding and unwinding of the wire rope in real time, and prevent slippage between the wire rope and the measuring wheel 11 and the drum, thus ensuring the accuracy of the measuring wheel 11 in measuring the sampling depth. At the same time, it prevents the slurry bucket 12 from shifting from the sampling point during the lifting and lowering process due to the shaking of the wire rope, thereby improving the sampling position accuracy and reducing equipment malfunctions.

[0047] In some embodiments, the sensor 16 includes at least one of a viscosity sensor 16, a density sensor 16, a pH sensor 16, and a liquid level sensor 16.

[0048] The optional configuration of various types of sensors 16 can be flexibly combined according to the actual testing needs of the project to achieve targeted testing of key performance parameters of mud. The sensors 16 are directly built into the mud sampling tank 12, which can be tested immediately after mud sampling, avoiding parameter distortion caused by environmental changes during sample transfer, and ensuring the authenticity and reliability of the test data.

[0049] In some embodiments, refer to Figure 1 and Figure 2 The winch 9 also includes a winch motor 17 that drives the drum to rotate. The winch 9 provides power for the drum rotation, enabling the wire rope to be wound and unwound. The winch motor 17 provides stable power for the drum rotation, replacing manual operation and realizing automated control of the lifting and lowering of the slurry collection bucket 12. Different types of winch motors 17 can adapt to different load requirements and control precision requirements. The servo motor 19 can achieve more precise control of the drum speed and rotation angle, thereby accurately adjusting the lifting speed and sampling depth of the slurry collection bucket 12.

[0050] In some embodiments, refer to Figure 1 and Figure 2It also includes a wired turntable 5, which includes a base 18 and a servo motor 19. The telescopic pole 15 is connected to the base through the base 18, and the servo motor 19 can drive the base 18 to rotate.

[0051] The wire-controlled turntable 5 drives the base 18 to rotate via the servo motor 19, which in turn drives the telescopic pole 15 to rotate (e.g., 360° or 90°), greatly expanding the coverage of the sampling mechanism. It can sample multiple sampling points around without moving the device, thus improving sampling efficiency. The servo motor 19 has high driving precision and can accurately control the rotation angle of the telescopic pole 15, ensuring that the slurry bucket 12 is accurately aligned with the sampling point.

[0052] In some embodiments, refer to Figure 1 and Figure 2 The traveling mechanism is a track 2 chassis 1. The track 2 chassis 1 includes a track 2, a gear motor 3, multiple track 2 gears, two drive wheels 13, and two driven wheels 14. The track 2 is tensioned on the multiple track 2 gears, and the gear motor 3 is connected to the drive wheels 13.

[0053] The two drive wheels 13 can move forward and backward via the control system, providing power. The two driven wheels 14 can turn left and right, controlling the direction.

[0054] The track 2 chassis 1 has a large contact area with the ground and a low ground pressure, which provides good passability and stability in complex construction sites such as mud and soft ground, and prevents the device from getting stuck or slipping. The gear motor 3 directly drives the drive wheel 13, which has high transmission efficiency and rapid power response, and can realize flexible start-stop and steering of the device. The track 2 is tensioned on multiple track 2 gears to ensure smooth operation of the track 2 and reduce the risk of track 2 falling off.

[0055] In some embodiments, refer to Figure 1 and Figure 2 It also includes an industrial control mechanism and an electrical box 7 mounted on the base. The industrial control mechanism includes an industrial control bracket 8 and a controller, which is electrically connected to a sensor 16, a hoisting motor 17, a servo motor 19, and a gear motor 3.

[0056] The controller is an industrial control computer or industrial control PC, which is equipped with a control system. The industrial control mechanism uses the controller to centrally control multiple components such as sensor 16 and hoist motor 17, coordinating the orderly operation of each component and realizing full automation of the sampling and detection process. The electrical box 7 provides safety protection and stable power supply for each electrical component, avoiding electrical failures caused by external environmental factors (such as rain and dust). The controller is electrically connected to each component, can receive the detection data of sensor 16 in real time, and send control commands according to the preset program, improving the intelligence and reliability of the device operation.

[0057] In some embodiments, refer to Figure 1 and Figure 2 It also includes a housing 6, which is mounted on the base to form a protective space. The wired control turntable 5, the industrial control mechanism, and the electrical box 7 are housed within this protective space.

[0058] In some embodiments, the controller has a storage module that records the distribution locations of all sampling points.

[0059] In this way, the control system can set several control points (i.e. sampling points) according to the engineering site layout map. The distance between control points should be 10 to 20m. The optimal starting point of the equipment is selected according to the control points. The in-situ sampling and detection device can automatically move to 2 to 3m away from the detection point according to the point map, and then make manual fine adjustments.

[0060] In some specific embodiments, the two driven wheels 14 are controlled by an automatic control device to determine the equipment's travel path. When the equipment reaches a set position of 2-3 meters, it is manually fine-tuned to the sampling position. The telescopic upright 15 is adjusted to a suitable height, and the telescopic crossbar 10 is adjusted to an operable length. Parameters such as the sampling position, number of sampling attempts, and safe lowering distance are set in the industrial control computer or industrial computer control system 20. The motor 17 is started to lower the sampling tank 12 and the sensor 16. When the equipment is lowered to the set position, the sensor 16 automatically detects the mud performance indicators, and the data is transmitted to the industrial control computer or industrial computer control system for data analysis and processing. The sampling tank 12 is then raised to complete the sampling.

[0061] In some embodiments, the controller includes an analysis module capable of planning an optimal route based on the distribution of all sampling points and the historical travel routes of the engineering mud in-situ sampling and detection device. That is, the control system has memory and analysis functions, automatically identifying and analyzing the traveled routes to select the optimal route.

[0062] In some embodiments, a charging pile is also included, which automatically travels to the charging pile to charge when the battery power of the engineering mud in-situ sampling and testing device is lower than the target battery power.

[0063] For example, when the battery level of the in-situ sampling and detection device is below 10%, it automatically moves to the charging station and starts the automatic charging mode.

[0064] The above technical solutions of the present invention are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made under the technical concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
