[0027] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0028] Please refer to Figures 1 to 4 The deep-water sampling device that is easy to take in this embodiment includes:

[0029] The bele pipe 1, water enters from the top pipe opening and discharges from the drain port with a valve at the bottom;

[0030] The water filter sleeve 21 has an inner outer dimension adapted to the outer contour of the Baylor tube 1. The Baylor tube 1 is placed inside and contacts the outer tube wall of the Baylor tube 1 through the rubber layer 22 of the inner tube wall. The cylinder body is opened at the top of the Baylor tube 1 and the area above the height, which serves as an observation port 23. A detachable cylinder cover 24 with a pull rope device is provided on the top of the cylinder.

[0031] The sealing cover assembly of the bailer tube 1 is sealed on the top pipe opening of the bailer tube 1, and a vertical spacing is left between the bailer tube 1 and the pull rope device, including a sealing plug cover 31 and a top cover 35. The sealing plug cover 31 has a water inlet hole 32 opened in the center, which is screwed on the top pipe opening of the bailer tube 1 through a thread. A vertically displaceable water inlet plate 33 is horizontally suspended at the water inlet hole 32. The water inlet plate 33 has a water hole, and a bolt column 34 is arranged in the center, which is connected to one end of the connecting rope 41 through the bolt column 34. The other end of the connecting rope 41 is arranged on the pull rope device. A through hole 36 for the bolt column 34 to pass through is arranged in the center of the top cover 35 according to the position of the bolt column 34 and the outer diameter thereof. In the initial state, 35 is located directly above the sealing plug cover 31 and the bolt column 34, with a vertical spacing therebetween. It can rely on external force to vertically displace downward until it is tightly attached to the sealing plug cover 31, and is kept in close contact with the sealing plug cover 31 by the limiting structure, forming a cover for the top end of the Baylor tube 1. When the limiting structure is released, it can restore to the initial position through the reset structure. The contact surfaces are sealed by the sealing gasket 37 at the bottom end of the top cover 35. The bolt column 34 passes through the through hole 36 and is sealed with the through hole 36 by the sealing layer 38 on the hole wall. The water inlet plate 33 can vertically displace by pulling the bolt column 34 through the connecting rope 41 through the pull rope device.

[0032] In a specific implementation, the corresponding structural setting of the device also includes:

[0033] The covering method between the cylinder cover 24 and the water filter sleeve 21 can be to screw the cylinder cover 24 onto the top of the water filter sleeve 21, or to snap the cylinder cover 24 into the top of the water filter sleeve 21, or to design the cylinder cover 24 as a flip cover, all of which are commonly used technical means, and it is only necessary to ensure that the cylinder cover 24 and the water filter sleeve 21 are separable, and no further details will be given.

[0034] The rope pulling device includes a rope winding roller 42 and a hand crank handle 43. The connecting rope 41 is wound around the rope winding roller 42, and the rope end is fixed to the rope winding roller 42. The rope winding roller 42 is rotatably mounted on the top of the water filter sleeve 21 around the central axis and is horizontally arranged in the direction of the central axis. One end of the roller shaft is exposed outside the water filter sleeve 21 and is connected to the hand crank handle 43.

[0035] The reset structure includes a connecting column 39 and a reset spring 310. A plurality of connecting columns 39 extending downward are provided at the bottom of the top cover 35. A plurality of concave connecting grooves 311 are formed at the top of the sealing plug cover 31 according to the position distribution and the corresponding outer dimensions of each connecting column 39. A reset spring 310 that deforms vertically is connected between the bottom end of the connecting column 39 and the bottom of the connecting groove 311. When the top cover 35 is moved to be tightly attached to the sealing plug cover 31, the connecting column 39 is adaptively inserted into the connecting groove 311. When the limiting structure releases the limit, it is detached to the top of the connecting groove 311 by relying on the elastic force of the reset spring 310.

[0036] The limiting structure includes a limiting block 312, a limiting groove 313, and a limiting spring 314. The limiting block 312 is a short plate, and is provided with at least two of them, which are respectively built into the grooves opened along the radial direction of the water filter sleeve 21 at the lower end of the connecting column 39, and the limiting spring 314 that deforms radially along the water filter sleeve 21 is connected to the groove bottom of the groove. In each connecting groove 311 of the sealing plug cover 31, a matching limiting groove 313 is opened according to the position and outer dimensions of the limiting block 312 on the corresponding connecting column 39. The limiting groove 313 is an arc groove coaxially distributed with the water filter sleeve 21, and is concave outward along the radial direction of the water filter sleeve 21. The connection between the upper and lower ends and the groove wall of the connecting groove 311 is smoothly transitioned by chamfering. When the top cover 35 is in the initial state, the lower end of the connecting column 39 with the limiting block 312 extends into the connecting groove 311, the limiting block 312 is completely built into the groove, and the limiting spring 314 is compressed. When the top cover 35 is moved to be closely attached to the sealing plug cover 31 , the limiting block 312 extends outwardly along the radial direction of the water filter sleeve 21 under the elastic force of the limiting spring 314 until it is stuck in the corresponding limiting groove 313 .

[0037] The water inlet plate 33 is a plate body with a plurality of water holes spaced apart along the circumferential direction, and can be vertically displaced along the axial direction in the water inlet hole 32 by the pulling of the connecting rope 41, and is always located in the water inlet hole 32, with the outer edge in contact with the hole wall of the water inlet hole 32. In this embodiment, the water inlet plate 33 is configured as a fan blade structure, and the water holes are between two adjacent fan blades.

[0038] Open the cover 24 of the water filter sleeve 21, take out the Baylor tube 1 for sampling, and after sampling, use the Baylor tube 1 sealing cover assembly to seal the top pipe opening. The operation method of sealing the top pipe opening of the Baylor tube 1 by the Baylor tube 1 sealing cover assembly can refer to:

[0039] Take the top cover 35 in the initial state as an example. Figure 1 and Figure 2 As shown, at this time, there is a vertical gap between the top cover 35 and the sealing plug cover 31, and the through hole 36 in the center of the top cover 35 does not contact the bolt 34, which is in a smooth state. Press the top cover 35 downward by hand to make the top cover 35 move vertically downward. During this process, firstly, the connecting column 39 of the reset structure moves downward to be inserted into the connecting groove 311, and the reset spring 310 is compressed. Secondly, the limiting block 312 of the limiting structure moves downward with the top cover 35 until the sealing gasket 37 at the bottom end of the top cover 35 is tightly attached to the sealing plug cover 31. The limiting block 312 encounters the limiting groove 313, and under the elastic force of the limiting spring 314, it extends outward along the radial direction of the water filter sleeve 21 and is stuck in the limiting groove 313, forming a lock on the current position of the top cover 35. At this time, the bolt 34 also penetrates the through hole 36, so that the top cover 35 and the sealing plug cover 31 form a cover on the top end of the Baylor tube 1.

[0040] If you want to open the bell tube 1 again, you only need to manually pull up the top cover 35. Since the upper and lower ends of the limiting groove 313 and the groove wall of the connecting groove 311 are chamfered, the resistance of the limiting structure can be overcome by manpower, so that the limiting block 312 is separated from the limiting groove 313. Under the elastic force of the reset spring 310, the top cover 35 can be restored to its initial posture, separated from the sealing plug cover 31, and the bolt column 34 is also separated from the through hole 36.

[0041] The use of the water inlet plate 33 at the water inlet hole 32 of the sealing plug cover 31 and the pull rope device is a further development of the function of the device, which can be implemented whether the Baylor tube 1 is taken out or the Baylor tube 1 is installed in the water filter sleeve 21. First, there are three options for the opening form at the top pipe mouth of the Baylor tube 1. One is to unscrew the sealing plug cover 31, at which time the top pipe mouth is completely exposed. The second is to pull the water inlet plate 33 upward through the connecting rope 41, detach from the water inlet hole 32, and expose it above the water inlet hole 32, located between the top cover 35 and the sealing plug cover 31. At this time, the water inlet hole 32 of the sealing plug cover 31 is completely exposed. The third is that the water inlet plate 33 is located in the water inlet hole 32, and water enters through the water hole on the water inlet plate 33.

[0042] After sampling, the beile tube 1 is placed in the water filter sleeve 21. If it is to be taken out, the outer wall of the beile tube 1 contacts and moves relative to the rubber layer 22 of the inner wall of the water filter sleeve 21 during the process of being separated from the water filter sleeve 21. The rubber layer 22 can effectively clean the water on the outer wall of the beile tube 1, making it convenient for the sampler to hold it. In addition, by providing the water filter sleeve 21, direct contact with the beile tube 1 is avoided, making it convenient to carry the beile tube 1.

[0043] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
