[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an adjustable depth sounder, comprising a base 1, a threaded sleeve 2 slidably connected inside the base 1, a fixing block 3 fixedly connected to the outer wall of the threaded sleeve 2, a sliding column 5 slidably connected inside the fixing block 3, the outer wall of the sliding column 5 slidably connected inside the threaded sleeve 2, a rotating ring 4 threadedly connected to the outer wall of the threaded sleeve 2, a connecting plate 6 fixedly connected to the outer wall of the sliding column 5, a connecting shaft 7 fixedly connected inside the connecting plate 6, an elastic plate 8 rotatably connected to the outer wall of the connecting shaft 7, the outer wall of the elastic plate 8 slidably connected inside the threaded sleeve 2, one end of a spring 9 fixedly connected to the lower surface of the sliding column 5, a conical block 10 fixedly connected to the other end of the spring 9, the upper surface of the conical block 10 fixedly connected to the lower surface of the threaded sleeve 2, and a support assembly provided on the upper surface of the base 1 for auxiliary support.

[0023] Specifically, the base 1 limits the threaded sleeve 2, the threaded sleeve 2 fixes the fixing block 3, and the fixing block 3 limits the sliding column 5. Pressing the sliding column 5 causes it to slide inside the threaded sleeve 2. While the sliding column 5 is sliding, the connecting plate 6 drives the elastic plate 8 to rotate on the outer wall of the connecting shaft 7. As the elastic plate 8 rotates, it slides inside the threaded sleeve 2. When the elastic plate 8 is fully inserted into the threaded sleeve 2, the conical block 10 is inserted into the soil layer. The shape of the conical block 10 makes it easier to enter the soil layer. The spring 9's rebound causes the elastic plate 8 to rotate out of the threaded sleeve 2, forming an open state. At this time, rotating the rotating ring 4 causes the threaded sleeve 2 to slide inside the base 1 until the rotating ring 4 is tightly attached to the base 1. The compression of the elastic plate 8 with the soil layer achieves a stable support effect for the entire device, avoiding shaking during winding or unwinding measurements, which would affect the measurement accuracy.

[0024] Reference Figure 3 The support assembly includes a support frame 11, the lower surface of which is fixedly connected to the upper surface of the base 1. A fixing plate 12 is fixedly connected to the outer wall of the support frame 11. A motor 14 is fixedly connected inside the support frame 11. A bidirectional threaded rod 15 is fixedly provided at the output end of the motor 14. The outer wall of the bidirectional threaded rod 15 is rotatably connected to the inside of the support frame 11. A moving block 16 is threadedly connected to the outer wall of the bidirectional threaded rod 15. A rotating shaft 17 is fixedly connected inside the moving block 16. A rotating plate 18 is rotatably connected to the outer wall of the rotating shaft 17. A rotating shaft 19 is rotatably connected inside the rotating plate 18. A connecting block 20 is fixedly connected to the outer wall of the rotating shaft 19. A sliding plate 21 is fixedly connected to the lower surface of the connecting block 20. A limit post 13 is slidably connected inside the sliding plate 21. The outer wall of the limit post 13 is fixedly connected to the inside of the fixing plate 12. The lower surface of the limit post 13 is fixedly connected to the upper surface of the base 1.

[0025] Specifically, the base 1 fixes the support frame 11, which in turn fixes the motor 14. Starting the motor 14 drives the bidirectional threaded rod 15 to rotate inside the support frame 11. Simultaneously, the rotation of the bidirectional threaded rod 15 causes two moving blocks 16 to move towards each other. The movement of the moving blocks 16 also causes the rotating plate 18 to rotate on the outer wall of the rotating shaft 17. The rotation of the rotating plate 18 on the outer wall of the rotating shaft 19 causes the connecting block 20 to move. The connecting block 20 causes the sliding plate 21 to slide on the outer wall of the limiting post 13. While the sliding plate 21 slides, the limiting post 13 limits its movement. The fixing plate 12 fixes the limiting post 13, and the support frame 11 also fixes the fixing plate 12. This achieves the effect of raising and lowering the sliding plate 21. Adjusting the height of the depth sounder allows for more accurate measurements, thus improving measurement precision.

[0026] Reference Figure 3 A connecting plate 22 is fixedly connected to the lower surface of the sliding plate 21. A motor 23 is fixedly connected inside the connecting plate 22. A unwinding roller 24 is fixedly installed at the output end of the motor 23. One end of a measuring rope 25 is fixedly connected to the outer wall of the unwinding roller 24. A counterweight 26 is fixedly connected to the other end of the measuring rope 25.

[0027] Specifically, the sliding plate 21 fixes the connecting plate 22, which in turn fixes the motor 23. By starting the motor 23, the unwinding roller 24 rotates, achieving rapid winding, saving manpower and improving winding efficiency. The rotation of the measuring rope 25 moves the counterweight 26, thus measuring the depth. When the counterweight 26 reaches the bottom of the desired measurement location, the measurement result is obtained by reading the value on the measuring rope 25, achieving the effect of measuring the depth.

[0028] Working principle: When the depth sounder is needed, firstly, by pressing the sliding column 5, it slides inside the fixed block 3, which in turn drives the elastic plate 8 to slide inside the threaded sleeve 2. At this time, the conical block 10 is inserted into the soil layer, and pressing the sliding column 5 is stopped. Through the rebound action of the spring 9, the sliding column 5 slides inside the threaded sleeve 2, and at the same time, the elastic plate 8 rotates on the outer wall of the connecting shaft 7. Then, by rotating the rotating ring 4, the threaded sleeve 2 slides inside the base 1, thereby achieving the function of stabilizing the support frame 11. When it is necessary to adjust the height of the sounder, the motor 14 is started to drive the bidirectional threaded rod 15 to rotate inside the support frame 11. The movement of the motor causes the moving block 16 to move, which in turn causes the rotating plate 18 to rotate on the outer wall of the rotating shaft 17 and the rotating shaft 29. As the rotating plate 18 rotates, it causes the connecting block 20 to move, which in turn causes the sliding plate 21 to slide on the outer wall of the limiting post 13, thereby adjusting the height of the unwinding roller 24. When measurement begins, the motor 23 is started to drive the unwinding roller 24 to rotate, thereby achieving the effect of winding the measuring rope 25. The counterweight 26 is lowered to measure the depth. This device can not only achieve the effect of stabilizing the depth sounder and ensuring its accuracy, but also achieve the effect of adjusting the height of the unwinding roller, thereby improving the accuracy of the measurement.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
