Detailed Implementation

[0029] 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.

[0030] The purpose of this invention is to provide a depth measuring device to solve the problems existing in the prior art, improve the efficiency of brine depth measuring in salt lake mining, and extend the service life of the depth measuring device.

[0031] 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.

[0032] This invention provides a depth sounding device, including an installation assembly 100, a depth sounding assembly 200, and a drive assembly 300. The installation assembly 100 can be connected to a water sampling machine. The depth sounding assembly 200 includes a first connecting rod 1, an upper rocker arm 2, a second connecting rod 3, and a lower rocker arm 4 connected in sequence. The first connecting rod 1, the upper rocker arm 2, the second connecting rod 3, and the lower rocker arm 4 are hinged to form a parallelogram mechanism. An angle sensor 6 is connected to the upper rocker arm 2. The first connecting rod 1 is connected to the installation assembly 100 and is arranged parallel to the vertical direction. The second connecting rod 3 is connected to a depth sounding rod 5. The drive assembly 300 is connected to the installation assembly 100 and includes a driver. The output end of the driver is connected to the upper rocker arm 2, and the output axis of the driver coincides with the hinge axis of the upper rocker arm 2 and the first connecting rod 1.

[0033] The depth measuring device of this invention is connected to a water sampling machine via an installation assembly 100. The installation assembly 100 provides stable support for the depth measuring assembly 200 and the drive assembly 300. The depth measuring assembly 200, consisting of a first connecting rod 1, an upper rocker arm 2, a second connecting rod 3, and a lower rocker arm 4, forms a parallelogram mechanism. The first connecting rod 1 and the second connecting rod 3 are parallel to the vertical direction. The drive unit rotates the upper rocker arm 2, thereby using the parallelogram mechanism to move the depth measuring rod 5 vertically to measure the depth of the brine. An angle sensor 6 monitors the rotation angle of the upper rocker arm 2 and calculates the brine depth. This depth measuring device, fixed to the water sampling machine by the installation assembly 100 and driven by the drive assembly 300, improves the efficiency of depth measuring, reduces the workload of operators, and uses the angle sensor 6 to monitor the rotation angle of the upper rocker arm 2 to obtain depth data. Its size is significantly smaller than existing devices, and it does not restrict the harvesting behavior of the cutting head when the water sampling machine is close to the shore, thus extending the service life of the depth measuring device. It should be explained here that the two ends of the first link 1 and the second link 3 are hinged to the upper rocker arm 2 and the lower rocker arm 4, respectively. In order to improve the structural strength of the parallelogram mechanism, the first link 1, the upper rocker arm 2, the second link 3 and the lower rocker arm 4 can be made of aluminum alloy, which is lightweight and stable. The first link 1, the upper rocker arm 2, the second link 3 and the lower rocker arm 4 form a parallelogram mechanism. The parallelogram mechanism is common knowledge to those skilled in the art and will not be described in detail here.

[0034] It should also be emphasized that, in practical applications, the controller can be used to control the operating state of the driver. For details regarding the downward movement of the sounding rod 5 for depth measurement, please refer to [link / reference needed]. Figure 5 When the sounding rod 5 touches the surface of the salt mine, it will be subjected to an upward reaction force from the salt mine surface. This reaction force counteracts the force transmitted from the actuator to the sounding rod 5. The controller controls the working state of the actuator, using a parallelogram mechanism to drive the sounding rod 5 upward to return to its initial position. Figure 1 As shown, the entire movement of the sounding rod 5 is completed. The controller repeats the sounding process at regular intervals to improve the efficiency of the sounding operation. Similarly, the controller receives angle information from the angle sensor 6 and calculates the brine depth.

[0035] Specifically, the drive assembly 300 also includes a clamping connecting plate 7 and a fixing clamp 8. The output end of the driver is connected to the clamping connecting plate 7 for transmission, and the fixing clamp 8 is connected to the clamping connecting plate 7. The fixing clamp 8 can clamp the upper rocker arm 2. The rotation axis of the clamping connecting plate 7 coincides with the hinge axis of the upper rocker arm 2 and the first connecting rod 1. During depth detection, the driver drives the clamping connecting plate 7 to rotate, and the fixing clamp 8 fixes the upper rocker arm 2 on the clamping connecting plate 7, thereby realizing that the driver drives the upper rocker arm 2 to rotate. The parallelogram mechanism drives the depth measuring rod 5 to move, which improves the reliability of the reciprocating motion of the depth measuring rod 5 and ensures the smooth progress of the depth measurement work.

[0036] The fixing fixture 8 includes two side plates 801 and two connecting blocks 802. One side plate 801 is connected to the fixture connecting plate 7. The two side plates 801 are symmetrically arranged around the upper rocker arm 2. The connecting blocks 802 connect the two side plates 801 and connect the upper and lower ends of the side plates 801 respectively. The two connecting blocks 802 and the two side plates 801 form a channel that allows the upper rocker arm 2 to pass through. The side plates 801 and the connecting blocks 802 cooperate to clamp the upper rocker arm 2. The fixing fixture 8 adopts a split structure, which facilitates the disassembly and assembly of the device.

[0037] In this specific embodiment, there are two sets of fixing clamps 8, which are symmetrically arranged with the rotation axis of the clamp connecting plate 7 as the axis of symmetry, further improving the working reliability of the fixing clamps 8 and improving the uniformity of force on the upper rocker arm 2. In practical applications, the connecting block 802 is bolted to the side plate 801, which is secure and easy to assemble and disassemble.

[0038] More specifically, the driver is a rotary cylinder, and the output end of the driver is connected to a variable diameter shaft 9. The variable diameter shaft 9 is connected to the fixture connecting plate 7 via a spline sleeve 10. The variable diameter shaft 9 and the spline sleeve 10 are keyed together, which is convenient and can ensure smooth torque transmission. The angle sensor 6 is connected to the variable diameter shaft 9 via a coupling, so that the angle sensor 6 can rotate synchronously with the variable diameter shaft 9 to monitor the rotation angle of the upper rocker arm 2.

[0039] Furthermore, the mounting assembly 100 includes a mounting base 11, a drive bracket 12, and a connecting rod bracket 13. Both the drive bracket 12 and the connecting rod bracket 13 are connected to the mounting base 11. The mounting base 11 can be connected to the top of the water sampling machine cutting head. The driver is fixed on the drive bracket 12, providing stable support for the driver. The second connecting rod 3 is connected to the connecting rod bracket 13, ensuring that the second connecting rod 3 is set parallel to the vertical direction, thereby ensuring that the sounding rod 5 can move in the vertical direction.

[0040] In practical applications, the mounting base 11 can be configured as a frame structure to improve the stability of the device while making the device as lightweight as possible and improving the adaptability of the depth sounding device.

[0041] Meanwhile, the depth sounding assembly 200 also includes a fixing plate 14, which is connected to the second connecting rod 3 and the depth sounding rod 5. The fixing plate 14 is used to install the depth sounding rod 5, facilitating its disassembly and maintenance, and effectively preventing the depth sounding rod 5 from interfering with the smooth rotation of the second connecting rod 3. It should also be noted that the depth sounding rod 5 can be made of fiberglass. In this specific embodiment, the depth sounding rod 5 is 2 meters long. In practical applications, other specifications of depth sounding rods 5 can be selected to meet production needs.

[0042] In other specific embodiments of the present invention, the second connecting rod 3 is L-shaped to facilitate the connection and fixation of the fixing plate 14. The depth measuring rod 5 is connected to the fixing plate 14 by means of a buckle 15. Multiple buckles 15 can be set to improve the connection between the depth measuring rod 5 and the fixing plate 14 and improve the working reliability of the depth measuring rod 5.

[0043] Furthermore, a counterweight is connected to the end of the upper rocker arm 2 away from the depth measuring rod 5, which effectively improves the dynamic balance of the parallelogram mechanism and ensures the working reliability of the depth measuring device. The mass of the counterweight can be adjusted according to the actual test results to improve the flexibility and adaptability of the depth measuring device.

[0044] The depth measuring device of this invention has a mounting base 11 fixed to the top of the cutting head of a water-mining machine. A drive bracket 12 and a connecting rod bracket 13 are fixed to the mounting base 11. A driver is mounted on the drive bracket 12. The driver's rotation drives the variable-diameter shaft 9 and the angle sensor 6 to rotate. The rotation of the variable-diameter shaft 9 drives the clamp connecting plate 7 to rotate, which in turn drives the upper rocker arm 2 to move. This converts the rotational motion of the driver into the up-and-down movement of the depth measuring rod 5. The controller can directly calculate the brine measurement depth based on the driver's rotation angle when the depth measuring rod 5 touches the bottom. Simultaneously, a counterweight is provided on the other side of the upper rocker arm 2 in the parallelogram mechanism to maintain the dynamic balance of the parallelogram mechanism. Furthermore, this invention has an active recovery function, which can effectively avoid the problem of continuous damage to the water-mining machine from salt mine compression, and can quickly and in real-time obtain the measurement of brine depth during wet salt mining.

[0045] 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.
