Description

Technical Field

[0001] This utility model relates to the field of water quality analysis equipment technology, and in particular to a portable water quality analyzer. Background Technology

[0002] Water quality analyzers are divided into three types: simplified analysis, comprehensive analysis, and specialized analysis. Simplified analysis is conducted in the field, analyzing fewer items, but requires speed and timeliness, and is suitable for preliminary understanding of the main chemical components of groundwater in various aquifers over a large area. Specialized analysis items are determined according to the specific needs of the task. Additionally, they can perform rapid and accurate qualitative and quantitative analysis, and can be fully automated, intelligent, online in real time, and perform multi-parameter analysis simultaneously.

[0003] Existing water quality analyzers typically include a housing and a cable retractor housed within the housing. The cable retractor is used to wind up the data cable, enabling personnel to perform water quality testing more efficiently and conveniently. However, in actual use, since water quality testing is generally conducted in the field in relatively harsh environments, the data cable is often dragged on the ground during use, easily accumulating mud and water stains on its outer surface. After use, if the data cable is directly wound up for storage, the mud and water stains will remain on the cable. Prolonged storage of the data cable can lead to corrosion and the development of unpleasant odors. In particular, if the data cable is stored inside the housing, the water stains adhering to the cable may damage the water quality analyzer.

[0004] Therefore, existing water quality analyzers suffer from the technical problem of unreasonable cable management. Summary of the Invention

[0005] This utility model provides a convenient water quality analyzer that solves the technical problem of unreasonable cable management in existing water quality analyzers.

[0035] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0036] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0037] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] Reference Figures 1 to 6 As shown, a portable water quality analyzer includes a chassis 1, which includes a housing and a cover 11 disposed on the housing. A water quality analysis component is disposed inside the housing, and the cover 11 is rotatably connected to the housing.

[0039] The water quality analysis component includes an analyzer 12 and a detection head disposed on the analyzer 12, the detection head being connected to the analyzer 12 via a cable;

[0040] The chassis 1 is provided with a cable storage assembly for storing the cables, and the cable storage assembly is located on the side of the chassis away from the cover 11.

[0041] The cable storage assembly includes a cable reel 2, which includes a cable reel 21 rotatably connected to the housing. The housing is also provided with a locking mechanism for locking the cable reel 21, and the cable reel 21 is provided with a cable groove 211 for accommodating cables.

[0042] In this solution, the take-up reel 21 is manually rotated to take in the cable. Since cables of different lengths may require the take-up reel 21 to rotate different numbers of times, manually rotating the take-up reel 21 is more conducive to cable take-in. Furthermore, manually rotating the take-up reel 21 simplifies the structure of the water quality analyzer and reduces the operating cost of the water quality analyzer.

[0043] One end of the cable is equipped with a detection head, and the other end of the cable is plugged into the analyzer 12. When storing the cable, the cable is detached from the analyzer 12 so that the end of the cable away from the detection head is free, making it easier to store the cable.

[0044] Both the detection head and the analyzer 12 are conventional water quality analysis elements, and their specific structure and working principle are based on existing technologies.

[0045] Reference Figures 3 to 6 As shown, in some embodiments, the housing is provided with a rotating shaft 22, the rotating shaft 22 is fixed to the housing, the take-up reel 21 is provided with a through hole that cooperates with the rotating shaft 22, and the take-up reel 21 is rotatably connected to the housing through the rotating shaft 22.

[0046] The rotating shaft 22 can be mounted on the housing via a flange. The flange can be fixed to the housing with screws, or it can be welded to the housing. The rotating shaft 22 and the flange can be an integral structure.

[0047] The rotating shaft 22 is cylindrical. A rolling bearing can be installed between the rotating shaft 22 and the through hole.

[0048] In some embodiments, the locking mechanism includes a locking block 23, the rotating shaft 22 is a hollow structure, the locking block 23 is located inside the rotating shaft 22, the side wall of the rotating shaft 22 is provided with a strip groove 221, the strip groove 221 penetrates the side wall of the rotating shaft 22, and the strip groove 221 cooperates with the locking block 23, the take-up reel 21 is provided with a locking groove 212 that cooperates with the locking block 23, the rotating shaft 22 is also provided with a push block 24 that pushes the locking block 23 to cooperate with the locking groove 212, and the locking block 23 is installed inside the rotating shaft 22 by disengaging the locking block 23 from the locking groove 212 through the elastic arm 25.

[0049] In some embodiments, the push block 24 is provided with a tapered portion 241, which pushes the locking block 23 to overcome the elastic force of the elastic arm 25 and engage with the locking groove 212.

[0050] Reference Figures 3 to 6 As shown, in some embodiments, the push block 24 is threadedly mounted to the rotating shaft 22, the rotating shaft 22 is provided with an internal thread, and the push block 24 is provided with an external thread that mates with the internal thread of the rotating shaft 22.

[0051] The push block 24 includes a tapered portion 241 that contacts the elastic arm 25 and a cylindrical portion with external threads. The tapered portion 241 and the cylindrical portion are integral structures and are coaxially arranged.

[0052] In some embodiments, a portion of the push block 24 extends out of the rotating shaft 22, and the portion of the push block 24 extending out of the rotating shaft 22 is provided with a pattern to facilitate rotation of the push block 24.

[0053] In some embodiments, the locking groove 212 is elongated and is evenly distributed along the circumferential direction of the take-up reel 21.

[0054] In some embodiments, a sleeve 251 is further provided inside the rotating shaft 22, and the locking block 23 is installed in the sleeve 251 through the elastic arm 25. The sleeve 251 is installed in the rotating shaft 22 by threads. The rotating shaft 22 is provided with an internal thread, and the sleeve 251 is provided with an external thread that mates with the internal thread of the rotating shaft 22. There are multiple elastic arms 25, which are evenly distributed along the circumference of the sleeve 251. The locking block 23 is provided at the end of each elastic arm 25 away from the sleeve 251.

[0055] Specifically, when the tapered part 241 is not in contact with the elastic arm 25, the elastic arm 25 is not under any force. At this time, the locking block 23 is disengaged from the locking groove 212, and the take-up reel 21 can rotate normally relative to the rotating shaft 22 to realize take-up or unload.

[0056] When it is necessary to lock the take-up reel 21, rotate the push block 24 to move the push block 24 towards the elastic arm 25. At this time, the conical part 241 of the push block 24 contacts the elastic arm 25, and the elastic arm 25 undergoes elastic deformation under the force, which causes the locking block 23 to pass through the strip groove 221 and cooperate with the locking groove 212. After the locking block 23 cooperates with the locking groove 212, the take-up reel 21 is locked and cannot be rotated.

[0057] When it is necessary to release the take-up reel 21, rotate the push block 24 in the opposite direction to disengage the conical part 241 from the elastic arm 25, thereby disengaging the locking block 23 from the locking groove 212 and releasing the take-up reel 21.

[0058] In some embodiments, the cable retractor further includes a wiping device 3 for wiping the cable, and the cable after being wiped by the wiping device 3 is stored in the cable reel 21.

[0059] The wiping device 3 includes a base 31 fixed to the housing, a socket 32 ​​inserted into the base 31, and a first sponge block for wiping the cable and a second sponge block for wiping the water stains on the cable after the first sponge block has been used to wipe them apart between the base 31 and the socket 32. Both the base 31 and the socket 32 ​​are provided with the first sponge block and the second sponge block.

[0060] The first sponge block can absorb water to improve its cleaning effectiveness. The second sponge block can be dry to effectively absorb water stains adhering to the cables.

[0061] In some embodiments, during the cable release process, the cable should be fully released to the target length before being plugged into the analyzer 12. During the cable take-up process, the cable should be detached from the analyzer 12 first, and then the take-up reel 21 should be rotated to take up the cable.

[0062] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0063] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0064] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
