DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] The present application provides a salt lake brine fixed depth sampler, which is mainly used to solve the problem that due to the different brine depths and their composition and other parameters, sampling and analysis in different brine layers are required to achieve precise control and comprehensive utilization. The following technical solutions are provided, which will be described in detail below:

[0021] Example 1:

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, in some embodiments, it includes a base plate 1 and a depth-fixing rope 2, a sampling cylinder 3 is fixed at one end of the depth-fixing rope 2, a filter cylinder 4 is provided at the end of the sampling cylinder 3, a fixed plate 5 is fixedly installed on the base plate 1, and inclined fixed rods 6 are symmetrically fixed on the side walls of the fixed plate 5, and a fixed pulley 7 is rotatably connected between the fixed rods 6, the depth-fixing rope 2 is slidably connected to the axle of the fixed pulley 7 and a retracting mechanism 8 is provided at the other end of the depth-fixing rope 2; an electromagnetic valve 11 is fixedly installed at the bottom of the sampling cylinder 3; a control panel 12 is fixedly installed on the side of the fixed plate 5, and the control panel 12 is electrically connected to the electromagnetic valve 11; the retracting mechanism 8 includes a retracting plate 801 symmetrically fixed on the base plate 1, a motor 802 is fixedly installed on the base plate 1, the output shaft of the motor 802 is fixedly connected to a rotating rod 803, the rotating rod 803 is rotatably connected between the two retracting plates 801, the middle part of the rotating rod 803 is fixedly connected to a rotating drum 804, and the other end of the depth-fixing rope 2 is wrapped around the outer wall of the rotating drum 804.

[0023] Specifically: through the structural design of the fixed plate 5, the fixed rod 6 and the fixed pulley 7, the sampler can be ensured to remain stable during the sinking process, and the brine depth can be accurately controlled, thereby achieving precise sampling; a filter cylinder 4 is set at the end of the sampling tube 3, which can effectively filter out mud, impurities and other substances that may exist in the salt lake, ensuring the purity and accuracy of the sampling; the setting of the retraction mechanism 8 makes the retraction and extension of the fixed depth rope 2 more convenient and quick, and the operator can easily control the sinking and recovery process of the sampler, thereby improving work efficiency.

[0024] The working principle here is: when it is necessary to sample the brine of the salt lake, the operator first controls the motor 802 to start through the control panel 12, and the motor 802 drives the rotating rod 803 to rotate; the rotation of the rotating rod 803 causes the retractable plate 801 to shrink at the same time, and the fixed depth rope 2 is wound around the outer wall of the rotating drum 804, and the sampling drum 3 sinks to the set depth; when the sampling drum 3 reaches the predetermined depth, the control panel 12 controls the solenoid valve 11 to open through electrical connection. After the solenoid valve 11 is opened, the solenoid valve 11 fixed at the bottom opens, allowing brine to enter the sampling drum 3; when the sampling is completed, the solenoid valve 11 is closed, and the sampling drum 3 stops. To stop water inflow, the operator controls motor 802 via control panel 12 to reverse the rotation of motor 802. This reverse rotation of motor 802 causes rotating rod 803 to rotate in the opposite direction, causing sampling tube 3 to float upward. When sampling tube 3 reaches the surface, the operator stops motor 802, causing sampling tube 3 to stop floating, completing the recovery process. The circuit on control panel 12 enables precise control of solenoid valve 11 and motor 802, ensuring the accuracy and reliability of the sampling and recovery processes. The circuit may also include sensors or detectors for monitoring sampling depth or other parameters to ensure the accuracy and safety of the sampling process. Fixed pulley 7 can change the direction of movement of depth-fixing rope 2. When motor 802 drives retraction mechanism 8 to move, depth-fixing rope 2 is diverted by fixed pulley 7, allowing sampling tube 3 to sink or float along a predetermined trajectory, ensuring the accuracy and stability of the sampling process. It should be noted that motor 802 is prior art, and its working principle will not be described in detail here.

[0025] like Figure 1 、 Figure 2 、 Figure 3 As shown, in some embodiments, the outer wall of the sampling tube 3 is engraved with scales 9 along the length direction. The working principle here is that the scales 9 can enable people to judge the volume of water in the sampling tube 3 more accurately.

[0026] Example 2:

[0027] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0028] like Figure 1 、 Figure 4 As shown, in some embodiments, the filter cartridge 4 is threadedly connected to the bottom of the sampling cartridge 3 and a plurality of filter holes 10 are constructed on the filter cartridge 4. The working principle here is: some solid particles, such as mud, salt crystals, etc., may be suspended in the salt lake water; these solid particles can be effectively filtered out through the multiple filter holes 10 on the filter cartridge 4, making the sampled liquid purer; the filtering function of the filter cartridge 4 can effectively remove impurities, ensure the purity and consistency of the sampled liquid, and thus improve the accuracy and reliability of sampling.

[0029] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
