Problems solved by technology

[0003] At present, traditional water quality samplers can only achieve sampling at vertical depths. If the water sample is located obliquely below or above, it is difficult to collect, and traditional water quality samplers cannot achieve targeted adjustment of water quality according to actual conditions. The location of the sampling, and the volume of the sampler cannot be automatically adjusted according to the sampling volume, so the use has certain limitations

Embodiment 1

[0044] This embodiment provides a flexible and shrinkable water quality sampler, such as Figure 8 As shown, it includes a mounting bracket 1, a lifting unit installed on the mounting bracket 1, and a sleeve structure 2 that cooperates with the pulling unit to realize the contraction function. The upper end of the sleeve structure 2 is hinged with the mounting bracket 1, and the sleeve structure 2 includes A plurality of sleeve units 2.1 are sequentially socketed, and a sliding fit structure is provided between adjacent sleeve units 2.1 to realize an axial sliding fit between the two. The sleeve unit 2.1 located at the head of the sleeve structure 2 and the The casing unit 2.1 at the tail of the tube structure 2 is provided with a pulling connection part, and the area between the pulling connection parts is a contraction zone, and the length of the contraction zone can be changed by operating the pulling unit; the casing structure 2 There is a telescopic tube 3 inside, the wat...

Embodiment 2

[0050] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 1.

[0051] Such as Figure 8 As shown, it also includes an angle adjustment mechanism installed on the mounting bracket 1 and used to adjust the angle of the casing structure 2; the casing unit 2.1 located at the head of the casing structure 2 is provided with a hinge, and the hinge and the mounting bracket 1 hinged, the angle adjustment mechanism includes a motor 6, a gear one 7 located at the driving end of the motor 6, and a gear two 8 fixedly connected to the hinge, the gear one 7 meshes with the gear two 8.

[0052] The motor 6 directly drives the gear one 7 to rotate, and the gear two 8 is driven to rotate while the gear one 7 rotates, thereby realizing the swing of the casing structure 2 driven by the gear two 8, and the swing range of the sleeve structure 2 is realized by controlling the rotation range of the motor 6 adjust.

[0053] The design of the angle adjustment stru...

Embodiment 3

[0055] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 2.

[0056] Such as Figure 8 As shown, the lifting connection part is the lifting ring 1 symmetrically arranged on the casing unit 2.1 located at the head of the casing structure 2 and the lifting ring 2 symmetrically arranged on the casing unit 2.1 located at the tail of the casing structure 2 10. The pulling unit includes a wire winding machine 11 symmetrically installed on the installation bracket 1 , and the pull rope 16 on the wire winding machine 11 passes through the corresponding pulling ring one 9 and is fixedly connected with the corresponding pulling ring two 10 .

[0057] The stay rope 16 on the wire winding machine 11 passes through the corresponding lifting ring one 9 and is fixedly connected with the corresponding lifting ring two 10. When the wire winding machine 11 pulls the stay rope 16, the stay rope 16 is directly lifted The cannula unit farthest from the hinge ...

Abstract

The invention belongs to the technical field of water quality detection, and discloses a flexibly contractive water quality sampler. The water quality sampler comprises an installing support, a lift and pull unit installed on the installing support and a casing pipe structure cooperating with the lift and pull unit to achieve a function of contraction. The upper end of the casing pipe structure ishinged to the installing support, the casing pipe structure comprises a plurality of casing pipe units which are sequentially connected in a sleeved mode, a slide fit structure for achieving axial slide fit of the two adjacent casing pipe units is arranged between every two adjacent casing pipe units, lift and pull connection parts are arranged on the casing pipe unit located on the head of the casing pipe structure and the casing pipe unit located at the tail of the casing pipe structure respectively, the area located between the lift and pull connection parts is a contraction area, and changing of the length of the contraction area is achieved by operating the lift and pull units. According to the invention, the volume of the sampler can be automatically adjusted according to the sampling quantity, adjusting of the sampling position of the water quality sampler can be achieved as well, and meanwhile, water samples at the corners can be collected conveniently simultaneously.

Description

technical field [0001] The invention belongs to the technical field of water quality detection, and in particular relates to a flexibly shrinkable water quality sampler. Background technique [0002] With the continuous improvement of people's living standards, water is an indispensable resource in people's daily life, and water quality problems directly affect people's living environment. The sustainable use of water resources is an extremely important guarantee for the sustainable development of society and economy. In recent years, with the increasingly serious water pollution, water quality testing is of great significance as the basic work of water pollution control, and the water quality sampling work before water quality testing directly affects whether the water quality testing is accurate and whether the water quality testing work is effective. [0003] At present, traditional water quality samplers can only achieve sampling at vertical depths. If the water sample ...
