Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 - Figure 4 This embodiment of a water body monitoring sampling tube for environmental protection includes a fixed cylinder 1. A limiting strip 3 is fixedly connected to the inner wall of the top of the fixed cylinder 1, and a sliding rod 2 is slidably connected to the outer side of the limiting strip 3. A connecting cylinder 4 is fixedly connected to the bottom of the sliding rod 2, and a sampling tube 10 is fixedly connected to the bottom of the connecting cylinder 4. A piston 11 is slidably connected to the inner side of the sampling tube 10, and a piston rod 9 is fixedly connected to the top of the piston 11. The outer side of the piston rod 9 is slidably connected to the inner side of the sampling tube 10, and a fixed rod 9 is fixedly connected to the inner side of the fixed cylinder 1. A fixed shell 15 has a first block 16 slidably connected to its inner side. The inner side of the sliding rod 2 has multiple grooves that are adapted to the first block 16. The outer side of the first block 16 is movably inserted into the inner side of the corresponding groove. A second block 17 is fixedly connected to the right side of the first block 16. The outer side of the second block 17 is slidably connected to the inner side of the fixed shell 15. A third block 19 is rotatably connected to the inner side of the second block 17. A toggle block 20 is rotatably connected to the outer side of the third block 19. One side of the toggle block 20 is movably abutting against the right side of the fixed shell 15.

[0025] When the user turns the lever 20 at a 90-degree angle, the third block 19 starts to rotate and the second block 17 starts to drive the first block 16 to move horizontally. Then the small spring 18 can return to normal. Previously, the small spring 18 was in a compressed state. Then the first block 16 enters the corresponding groove. At this time, the fixing work between the fixed cylinder 1 and the sliding rod 2 is completed.

[0026] The connecting cylinder 4 is fixedly connected to a motor 5, the output end of the motor 5 is fixedly connected to a rotating screw 6, the outer side of the rotating screw 6 is threadedly connected to a lifting plate 8, the bottom of the lifting plate 8 is fixedly connected to the top of the piston rod 9, the outer side of the sampling tube 10 is rotatably connected to a valve cover 12, the inner side of the valve cover 12 is provided with an arc groove, one side of the valve cover 12 is fixedly connected to a traction rope 13, and the outer side of the traction rope 13 is movably sleeved with a bracket 14. The left side of the bracket 14 is fixedly connected to the outer side of the fixed cylinder 1, which allows the traction rope 13 to be limited, thereby preventing the rope from swinging wildly;

[0027] Among them, a small spring 18 is fixedly connected to one side of the first block 16, and the other end of the small spring 18 is fixedly connected to the inner wall of the right side of the fixed shell 15. A rounded corner is provided on one side of the actuating block 20. A scale 25 is fixedly connected to the top of the connecting cylinder 4. The outer side of the scale 25 is slidably connected to the inner side of the fixed cylinder 1, so that the user can know the distance the mechanism moves.

[0028] Among them, the inner side of the lifting plate 8 is slidably connected to two guide bars 7, and the top of the two guide bars 7 is fixedly connected to one side of the connecting cylinder 4. The outer side of the rotating screw 6 is rotatably connected to the inner side of the connecting cylinder 4. The outer side of the fixed cylinder 1 is fixedly sleeved with a fixed sleeve 21, which makes it easy for the user to hold the device.

[0029] The working principle of the above embodiments is as follows:

[0030] In use, the user holds the fixing sleeve 21 and then inserts the bottom end of the sampling tube 10 into the water body to be measured. When sampling at the corresponding depth to be measured, the valve cover 12 automatically closes the tube opening due to gravity, isolating the water body along the way. A sealing ring is provided between the valve cover 12 and the sampling tube 10. When the valve cover 12 and the sampling tube 10 rotate, a bending spring is provided between the valve cover 12 and the sampling tube 10 for connection. This makes it easy for the valve cover 12 and the sampling tube 10 to close tightly. After reaching the target depth, the traction rope 13 is pulled from the water surface, the valve cover 12 is lifted downward, and then the bottom opening of the sampling tube 10 opens. The user can start the motor 5 and then turn the screw 6 to start rotating. This allows the lifting plate 8 to move vertically. Then, the piston rod 9 starts to move synchronously, which makes the sampling tube 10 start to extract the sample.

[0031] The user releases the traction rope 13, and under the action of the bending spring, the valve cover 12 closes tightly again with the sampling tube 10. The user's sampling work is then completed. The valve cover 12 is designed to be fluid-like, which reduces resistance. The user can adjust the distance between the sliding rod 2 and the fixed cylinder 1. After adjustment, the user turns the toggle block 20 90 degrees. Then, block 19 starts to rotate, and block 17 starts to drive block 16 to move horizontally. Then, the small spring 18 can return to normal. Previously, the small spring 18 was in a compressed state. Then, block 16 enters the corresponding groove. At this time, the fixing work between the fixed cylinder 1 and the sliding rod 2 is completed, which facilitates the user to collect samples in water at different depths.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
