[0029] Example

[0030] Please see Figures 1 to 6 The main body of the device consists of two support blocks 9, a top plate 1 located on the upper end of the two support blocks 9, and a top frame 6 located at the top of the top plate 1. The inner wall of the top frame 6 is provided with a steel wire rope 5 for extending during the collection of deep geothermal well water. The end of the steel wire rope 5 is connected to a fixing plate 16. Connecting blocks 25 are fixed to both sides of the fixing plate 16. An installation bucket 12 is sleeved around the outer periphery of the two connecting blocks 25. An installation frame 20 communicating with the installation bucket 12 is provided around the outer periphery of the installation bucket 12. A third telescopic rod 19 is installed on the vertical side of the installation frame 20. A fixing plate 18 is installed on the moving part of the third telescopic rod 19. One of the connecting blocks 25 has a... There is a circular groove 27 for the fixed plate 18 to be inserted. The two connecting blocks 25 are provided with a moving groove 23 on the side that is close to each other. The vertical inner wall of the two moving grooves 23 is provided with a sliding groove 24. The steel wire rope 5 around the rotating rod is loosened by the rotary motor 3, so that the installation bucket 12 moves down and is put into the well. When it reaches a certain depth, the third telescopic rod 19 set on the side of the installation frame 20 controls the fixed plate 18 to disengage from the circular groove 27, so that the moving plate 21 disengages from the moving groove 23 on the side of the connecting block 25. Due to the limitation of the sliding groove 24 on the slider 28, the moving plate 21 moves down and drives the collection bucket 22 to follow, so that well water enters into it.

[0031] Subsequently, the fourth telescopic rod 26 set at the top of the connecting block 25 retracts, causing the collection bucket 22 to move upward again and be fixed against the collar 17, thereby avoiding the mixing and contamination of well water at different depths during the upward movement, facilitating the collection of well water at different depths, and improving the efficiency of use. The inner walls of the two sliding grooves 24 are tightly attached to the sliders 28, and the two sliders 28 are fixed with a moving plate 21. The vertical side of the moving plate 21 near the circular groove 27 is provided with a circular groove 27 of the same size. The top of one of the connecting blocks 25 is equipped with the fourth telescopic rod 26, and the moving plate 21 is installed on the moving part of the fourth telescopic rod 26. The collection bucket 22 is fixed between the two moving plates 21. The structure of the collection bucket 22 and the mounting bucket 12 can be appropriately weighted to facilitate sinking.

[0032] Both sides of the top frame 6 are fixed with partitions 7. A rotary motor 3 is installed on the vertical side of one of the partitions 7. The top of the top frame 6 is provided with a groove 4. A collar 17 that abuts against the collection bucket 22 is fitted around the inner circumference of the mounting bucket 12. A rotating rod is installed on the drive end of the rotary motor 3, and a steel wire rope 5 is sleeved around the outer circumference of the rotating rod. Both sides of the top plate 1 are fixed with vertical plates 2. The two support blocks 9 are provided with mounting grooves 14 on the side that is close to each other. A second telescopic rod 15 is installed on the vertical inner wall of both mounting grooves 14, and the vertical plate 2 is installed on the moving part of the second telescopic rod 15. An inclined plate 8 is fixed on the top of both support blocks 9. Both support blocks 9 have a fixing groove 11 at their bottom ends. Both support blocks 9 have a first telescopic rod 10 extending into the fixing groove 11 on their sides. Both first telescopic rods 10 have a clamping plate 13 installed on their moving parts. By using the fixing groove 11 on one side of the support block 9 and the first telescopic rod 10 on the vertical side of the support block 9, the clamping plate 13 is controlled to fix the entire device. Then, the second telescopic rod 15 is moved to drive the second telescopic rod 15 on the other side synchronously, so that the support block 9 on the other side can be moved, which makes it easy to place the collection device on geothermal wells of different sizes.

[0033] The rotary motor 3, the first telescopic rod 10, the second telescopic rod 15, the third telescopic rod 19, and the fourth telescopic rod 26 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] Working principle

[0035] This deep geothermal well water sample collection device operates as follows: The device is moved to a suitable geothermal well location. A rotary motor 3 controls a steel wire rope 5, causing the installation bucket 12 to descend into the well to a certain depth. Then, a third telescopic rod 19 on the side of the installation frame 20 controls the fixed plate 18 to disengage from the circular groove 27, causing the moving plate 21 to disengage from the moving groove 23 on the side of the connecting block 25. Constrained by the sliding groove 24 limiting the slider 28, the moving plate 21 descends, causing the collection bucket 22 to follow, allowing well water to enter. Subsequently, a fourth telescopic rod 26 at the top of the connecting block 25 retracts, causing the collection bucket 22 to rise again and be secured against the collar 17, thus preventing mixing and contamination of well water from different depths during the upward movement.
