Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 - Figure 5As shown, a groundwater monitoring device with a probe protection structure includes a monitoring instrument 1, a connecting line 20 and a probe body 21; a protective sleeve 22 is sleeved on the probe body 21, and a fixing mechanism is arranged on the protective sleeve 22, and the fixing mechanism includes a card block 24, and the card block 24 is inserted in a card slot 23, and the card slot 23 is arranged on the left and right sides of the probe body 21, the card block 24 is trapezoidal in design, and the card slot 23 is rectangular in design, and a first spring 25 is welded and fixed on a side of the card block 24 away from the card slot 23, and a side of the first spring 25 away from the card block 24 is welded and fixed on the inner wall of the first movable groove 26, and the bottom end of the card block 24 contacts with the top end of a movable sleeve 30, and two groups of fixed blocks 28 are welded and fixed on the movable sleeve 30, and a second spring 29 is welded and fixed on the fixed block 28, and the top end of the second spring 29 is welded and fixed on the inner wall of the second movable groove 27, and the first movable groove 26 and the second movable groove 27 are both arranged inside the protective sleeve 22, and the movable sleeve 30 contacts with the surface of the probe body 21;

[0024] During operation, a groundwater monitoring probe protection device in the above technology will inevitably produce wear on the surface of the protective plate during long-term use, and the protective plate is fixed to the probe main pipe by a spring, so it is difficult to disassemble and install the protective plate. The structural design of the fixing mechanism realizes the function of facilitating the disassembly and installation of the protective cover 22 from the probe body 21. When the protective cover 22 on the probe body 21 is to be disassembled, the movable cover 30 is first pushed upward, and the fixed block 28 fixed on the movable cover 30 will move in the second movable groove 27 and squeeze the second spring 29, and the top part of the movable cover 30 will contact with the second movable groove 27. The card block 24 abuts and pushes the card block 24 to move to both sides until the card block 24 is no longer inserted in the card slot 23. At this time, the protective cover 22 can be removed from the probe body 21. Similarly, when the protective cover 22 is to be fixed on the probe body 21 to protect the probe body 21, it is only necessary to put the protective cover 22 on the probe body 21 until the card block 24 is inserted into the card slot 23. The card block 24 is designed in a trapezoidal shape, and the top part of the movable sleeve 30 is provided with an inclined surface to facilitate better pushing the card block 24 to move. The second spring 29 is used to reset the movable sleeve 30 so that the movable sleeve 30 can return to its original position after releasing the hand.

[0025] Furthermore, the bottom end of the movable sleeve 30 is separately provided with threads, the movable sleeve 30 and the end cover 38 are threadedly connected, and a filter screen 39 is welded and fixed to the bottom end of the end cover 38;

[0026] During operation, the structural design of the end cover 38 and the filter screen 39 realizes the function of protecting the bottom part of the probe body 21. The filter screen 39 is used to filter the water quality to ensure that the probe body 21 can remain clean and free from contamination during the detection process. The end cover 38 is fixed to the bottom end of the movable sleeve 30 by a threaded connection to facilitate disassembly and installation.

[0027] Furthermore, four groups of grooves 36 are formed on the movable sleeve 30, and a long block 35 is slidably connected inside the groove 36, and the long block 35 is fixedly connected to the inner wall of the protective sleeve 22;

[0028] During operation, when the movable sleeve 30 is pushed to move, the four groups of long blocks 35 fixed on the inner wall of the protective sleeve 22 will slide out of the grooves 36, thereby ensuring the stability of the movable sleeve 30 during movement and preventing the movable sleeve 30 from shaking greatly.

[0029] Furthermore, an extension column 31 is welded and fixed on the top of the protective sleeve 22, and a rubber sleeve 32 is glued and fixed to the inner wall of the extension column 31, and the rubber sleeve 32 is in contact with the connecting wire 20;

[0030] During operation, the rubber sleeve 32 fixed on the inner wall of the extension column 31 contacts the surface of the connecting wire 20, so that when the protective sleeve 22 is sleeved on the probe body 21, the friction between the protective sleeve 22 and the connecting wire 20 can be increased, so that the protective sleeve 22 can be better fixed on the probe body 21.

[0031] Furthermore, the front and rear sides of the clamping block 24 are both welded with a limit block 34, and the limit block 34 is slidably connected to the inside of the limit groove 33, and the limit groove 33 is provided on the inner wall of the first movable groove 26;

[0032] During operation, the limit block 34 slides in the limit groove 33 to limit the movement range of the block 24 in the first movable groove 26 to prevent the block 24 from being over-stretched so that the first spring 25 cannot be used normally. At the same time, it can also limit the movement of the block 24 in the vertical direction.

[0033] Furthermore, the fixing block 28 is slidably connected to the fixing column 37, and the top and bottom ends of the fixing column 37 are fixed to the inner wall of the second movable groove 27 by welding;

[0034] During operation, the fixing block 28 slides on the fixing column 37 , and the second spring 29 is also sleeved on the fixing column 37 to facilitate the movement of the fixing block 28 in the second movable groove 27 .

[0035] Working principle: In the prior art, a groundwater monitoring probe protection device will inevitably wear out the surface of the protection plate during long-term use, and the protection plate is fixed to the probe main pipe by a spring, so it is difficult to disassemble and install the protection plate. In this case, a groundwater monitoring device with a probe protection structure realizes the function of facilitating the disassembly and installation of the protection cover 22 from the probe body 21 through the structural design of the fixing mechanism. When the protection cover 22 on the probe body 21 is to be disassembled, the movable cover 30 is first pushed up, and the fixed block 28 fixed on the movable cover 30 will move in the second movable groove 27 and squeeze the second spring 29. The top portion of the movable sleeve 30 will abut against the block 24 and push the block 24 to move to both sides until the block 24 is no longer inserted in the slot 23. At this time, the protective sleeve 22 can be removed from the probe body 21. Similarly, when the protective sleeve 22 is to be fixed on the probe body 21 to protect the probe body 21, it is only necessary to put the protective sleeve 22 on the probe body 21 until the block 24 is inserted into the slot 23. The block 24 is trapezoidal in design, and the top portion of the movable sleeve 30 is provided with an inclined surface to facilitate better pushing the block 24 to move. The second spring 29 is used to reset the movable sleeve 30 so that the movable sleeve 30 can return to its original position after releasing the hand.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
