The rotating angle of the depth measuring rod is monitored by using the angle sensor, the depth of the salt layer can be monitored in real time, the problem that the non-contact sensor cannot measure due to the fact that there are many suspended matters in the salt lake and the surface is easy to be salted is solved, and the working reliability of the depth measuring device is improved.

Description

Technical Field

[0001] This invention relates to the technical field of wet mining equipment for salt mines and its supporting facilities, and in particular to a passive depth sounding device. Background Technology

[0002] Currently, the Lop Nur salt fields are produced using wet mining with hydraulic pumps. The salt fields are artificially constructed at the designed locations according to the base elevation and foundation dimensions, and the depth of the salt fields is determined by design requirements. By introducing brine into the salt fields, the brine naturally evaporates, forming crystals at the bottom. The hydraulic pump, using its cutting head, extracts the salt ore, producing a slurry of the appropriate concentration for subsequent production processes. Accurate measurement of the brine depth effectively controls slurry concentration and mining efficiency, thereby improving the comprehensive utilization of resources and the efficiency and stability of production at Lop Nur Potash Co., Ltd.

[0003] The current water sampling machine uses a mechanical depth sounding device with a sliding rod, mainly composed of a frame, sliding rod, wire sensor, and accessories. Because the rate of salt formation varies at different locations at the bottom of the salt pond, resulting in an uneven bottom, the sliding rod easily gets stuck in the depressions. Continued movement can cause the sliding rod to bend, affecting measurement accuracy and accelerating wear and tear on the depth sounding device. The wire sensor's wire frequently rubs against the edge of the protective tube, eventually breaking and preventing data acquisition. Furthermore, the existing frame's mechanical structure is not stable enough; long-term use under gravity can cause it to bend and deform. Operating in the salt field environment easily leads to damage, increased measurement errors, low efficiency, and fails to meet operational needs.

[0004] Therefore, how to change the current situation in which depth sounding devices often deform or break during actual operation and cannot effectively measure depth has become an urgent problem for those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a passive depth sounding device to solve the problems existing in the prior art, improve the availability, durability and measurement accuracy of the depth sounding device, and ensure the normal operation of the depth sounding device.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a passive depth sounding device, comprising:

[0018] The present invention achieves the following technical effects compared to the prior art:

[0019] The passive depth sounding device of this invention has a support assembly connected to a water sampling machine. When depth sounding is required, the depth sounding rod in the depth sounding assembly is released. The depth sounding rod rotates around the support assembly, and its free end enters the brine and contacts the bottom of the salt pool. Due to the long length of the depth sounding rod, it is tilted. An angle sensor can monitor the rotation angle of the depth sounding rod, and the depth of the salt layer can be calculated. The forward support uses a diagonal bracing structure to avoid downward bending due to long-term gravity. When the water sampling machine is traveling, the free end of the depth sounding rod contacts the salt pool. When encountering protrusions and depressions at the bottom of the salt pond, the sounding rod, made of spring steel, can break free and return to its original shape after undergoing significant elastic deformation. Similarly, by using an angle sensor to monitor the rotation angle of the sounding rod, the purpose of real-time monitoring of salt layer depth can be achieved. This solves the problem of non-contact sensors being unable to measure due to the large amount of suspended matter and the easy formation of salt on the surface in salt lakes, thus improving the working reliability of the sounding device. At the same time, it avoids the problem of the sounding rod being easily damaged when encountering unevenness at the bottom of the salt pond, extending the service life of the device.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The purpose of this invention is to provide a passive depth sounding device to solve the problems existing in the prior art, improve the availability, durability and measurement accuracy of the depth sounding device, and ensure the normal operation of the depth sounding device.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The present invention provides a passive depth sounding device, including a support assembly 100 and a depth sounding assembly 200. The support assembly 100 can be connected to a water sampling machine. The depth sounding assembly 200 includes a depth sounding rod 1 and an angle sensor 2. One end of the depth sounding rod 1 is rotatably connected to the support assembly 100, and the other end of the depth sounding rod 1 is a free end that can extend into brine. The angle sensor 2 is connected to the depth sounding rod 1 and can monitor the rotation angle of the depth sounding rod 1.

[0031] The passive depth sounding device of this invention has a support assembly 100 connected to a water sampling machine. When depth sounding is required, the depth sounding rod 1 in the depth sounding assembly 200 is released. The depth sounding rod 1 rotates around the support assembly 100, and its free end enters the brine and contacts the bottom of the salt pool. Due to the relatively long length of the depth sounding rod 1, it is tilted. The angle sensor 2 can monitor the rotation angle of the depth sounding rod 1, and the depth of the salt layer can be calculated. The support assembly 100 has a slanted structure, which can prevent downward bending due to long-term gravity. When the water sampling machine is navigating, the depth sounding rod 1... The free end contacts the bottom of the salt pond. When encountering protrusions or depressions at the bottom, the sounding rod 1, made of spring steel, can break free and return to its original shape after significant elastic deformation. Similarly, the angle sensor 2 monitors the rotation angle of the sounding rod 1, enabling real-time monitoring of the salt depth. This solves the problem of non-contact sensors being unable to measure due to the large amount of suspended matter and easy salt formation on the surface in salt lakes, improving the reliability of the depth measuring device. It also avoids the problem of the sounding rod 1 being easily damaged by the unevenness of the salt pond bottom, extending the device's service life. It should be noted that calculating the salt depth using trigonometric functions based on the known rotation angle and length of the sounding rod 1 is a common practice among those skilled in the art and will not be elaborated upon here.

[0032] Specifically, the support assembly 100 includes a base 3 and a forward support 4, as detailed below. Figure 2 The front support 4 is connected to the base 3, and the base 3 ensures the height of the depth measuring component 200. The depth measuring component 200 is set at one end of the front support 4. The depth measuring rod 1 is rotatably connected to the front support 4. The front support 4 is set and the depth measuring rod 1 is rotatably set at one end of the front support 4. The front support 4 uses a diagonal structure, which can avoid the phenomenon of downward bending due to long-term gravity, ensure that the depth measuring rod 1 can rotate smoothly, reserve working space for the depth measuring rod 1, and ensure the normal operation of the device.

[0033] To improve the stability of the device, a counterweight element 5 is installed at the other end of the front probe support 4. The base 3 is located between the depth measuring component 200 and the counterweight element 5. The counterweight element 5 and the depth measuring component 200 are located at the two ends of the front probe support 4, which improves the balance of the device and ensures the reliability of the device.

[0034] In this specific embodiment, the counterweight element 5 includes several counterweight plates, which are detachably connected to the front support 4. The multiple counterweight plates facilitate adjustment of the weight of the counterweight element 5 according to specific working conditions, meeting various operational needs. The counterweight plates can be made of cast iron. When different depth measuring rods 1 are replaced, the number of counterweight plates can be adjusted accordingly. In this specific embodiment, the depth measuring rod 1 is a 3-meter-long spring steel depth measuring rod. In practical applications, adjustments can be made according to specific working conditions to improve the flexibility and adaptability of the device.

[0035] More specifically, the depth sounding component 200 also includes a base plate 6 and a rotating shaft 7, please refer to... Figure 3 The base plate 6 is connected to the front probe bracket 4. The base plate 6 facilitates the connection between the depth measuring component 200 and the front probe bracket 4. The rotating shaft 7 is rotatably connected to the base plate 6. The depth measuring rod 1 and the angle sensor 2 are both connected to the rotating shaft 7. The depth measuring rod 1 rotates using the rotating shaft 7, which improves the smoothness of the rotation of the depth measuring rod 1. The angle sensor 2 is connected to the rotating shaft 7, which ensures the accuracy of the angle sensor 2 in monitoring the rotation angle of the depth measuring rod 1.

[0036] A fastening sleeve 8 is provided between the depth measuring rod 1 and the rotating shaft 7. The fastening sleeve 8 is connected to the rotating shaft 7. The depth measuring rod 1 passes through the fastening sleeve 8 and is fixed by fastening screws 9. See details. Figure 3 and Figure 4 The rotating shaft 7 is connected to a fastening sleeve 8, which facilitates the connection and fixation of the depth measuring rod 1. The depth measuring rod 1 and the fastening sleeve 8 are fastened with fastening screws 9, which makes disassembly and assembly convenient and facilitates the replacement and maintenance of the depth measuring rod 1. At the same time, it can also make fine adjustments to the working length of the depth measuring rod 1.

[0037] In this specific embodiment, the substrate 6 is U-shaped, and the rotating shaft 7 rotatably passes through the two side walls of the substrate 6. The bottom wall of the substrate 6 is connected to the front probe bracket 4, which helps to improve the structural stability of the device. The depth measuring rod 1 and the angle sensor 2 are respectively set at both ends of the rotating shaft 7, which further improves the uniformity of the force on the substrate 6 and improves the structural strength of the device.

[0038] In addition, a rotating shaft sleeve 10 is provided between the rotating shaft 7 and the base plate 6. The rotating shaft sleeve 10 is connected to the base plate 6, and the rotating shaft 7 can rotatably pass through the rotating shaft sleeve 10. A bearing is provided between the rotating shaft 7 and the rotating shaft sleeve 10 to ensure the smooth rotation of the rotating shaft 7, thereby improving the rotation reliability of the depth measuring rod 1.

[0039] Furthermore, the base plate 6 is connected to a sensor bracket 11 and a protective cover 12. The angle sensor 2 is fixed on the sensor bracket 11 and connected to the rotating shaft 7 via a coupling. The angle sensor 2 and the sensor bracket 11 are both located within the space enclosed by the protective cover 12 and the base plate 6. A sealing gasket is also provided between the protective cover 12 and the base plate 6. Placing the angle sensor 2 within the space enclosed by the protective cover 12 and the base plate 6 effectively enhances the protection of the angle sensor 2, preventing damage from the brine and extending the service life of the device. It should be clarified here that "the angle sensor 2 is connected to the rotating shaft 7" specifically means that the detection element of the angle sensor 2 is connected to the rotating shaft 7 to monitor the rotation angle of the rotating shaft 7. "The angle sensor 2 is fixed on the sensor bracket 11" means that the housing of the angle sensor 2 is fixed on the sensor bracket 11. Therefore, the above descriptions are not contradictory.

[0040] It should also be noted that the front probe bracket 4 is connected to the bracket sleeve 13, which is connected to the base plate 6, facilitating the connection between the depth measuring component 200 and the front probe bracket 4 and improving operational convenience. In addition, both the front probe bracket 4 and the base 3 are frame structures, which helps to reduce the weight of the device and improve the adaptability of the depth measuring device.

[0041] The passive depth sounding device of this invention has a base 3 fixed to the surface of the cutting head of a water-collecting machine, a forward probe 4 fixed to the base 3, and a depth sounding component 200 mounted on the forward probe 4. When the water-collecting machine is navigating, the depth sounding rod 1 in the depth sounding component 200 contacts the bottom salt deposit, causing the rotating shaft 7 to rotate. The rotating shaft 7, through a coupling, drives the angle sensor 2 to rotate, thereby obtaining the rotation angle of the depth sounding rod 1 during the water-collecting process. After trigonometric function conversion, the real-time distance of the depth sounding device relative to the salt layer can be obtained. Furthermore, a protective cover 12 is installed at the angle sensor 2 position, enabling long-term steady-state operation in the special environment of salt lakes. This invention employs a passive depth sounding method, effectively solving the problem of non-contact sensors being unable to measure due to the large amount of suspended matter and easy salt deposition on the surface in salt lakes.

[0042] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
