Description

Technical Field

[0001] This utility model relates to the field of water quality analyzer sampling equipment, and in particular to a sampling device for a multi-parameter water quality analyzer. Background Technology

[0002] Multi-parameter water quality analyzers are a new generation of water quality testing instruments, mainly used in various fields such as marine, industrial production, environmental protection, aquaculture, and wastewater treatment. They can simultaneously detect multiple parameters in water, such as pH, dissolved oxygen, turbidity, conductivity, residual chlorine, redox potential, temperature, salinity, chloride, mineralization, and heavy metals, providing comprehensive data support for water quality safety.

[0003] Regarding sampling devices, multi-parameter water quality analyzers are typically equipped with dedicated sampling bottles, sampling tubes, or samplers for collecting water samples from the water body being tested. Sampling bottles are generally made of materials such as glass or plastic, featuring good sealing and corrosion resistance to ensure the purity and representativeness of the water sample. Samplers usually have adjustable sampling depth and volume, allowing users to perform sampling operations according to their actual needs.

[0004] Currently, a major problem in the practical application of sampling devices for multi-parameter water quality analyzers is that the sampling equipment is usually separate from the water quality analyzer. This means that users must additionally confirm whether they have brought the sampling equipment when going out to collect samples, which undoubtedly increases the preparation work and carrying burden before sampling.

[0005] More importantly, in some situations, sampling personnel may need to collect water from deeper waters. When using handheld sampling devices for this purpose, difficulties often arise, sometimes making it impossible to complete the sampling task. This is because handheld sampling devices have limited length and flexibility, making it difficult to reach deeper waters for sampling. Utility Model Content

[0006] The main objective of this invention is to provide a sampling device for a multi-parameter water quality analyzer, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A sampling device for a multi-parameter water quality analyzer includes a water quality analyzer, an upper cover, and a control panel. The upper cover is connected to the water quality analyzer via a hinge device, and the control panel is located on the upper inclined surface of the water quality analyzer. The water quality analyzer is operated to perform water quality testing via the control panel.

[0009] The upper end of the water quality testing instrument is connected to a detachable storage cover via a locking device, and the lower end of the detachable storage cover has a storage cavity. The storage cavity contains multiple sampling tubes. The sampling tubes can be taken out by opening the detachable storage cover, and water quality sampling can be performed through the sampling tubes.

[0010] The side wall of the detachable storage cover is inserted with multiple limiting rods. Each limiting rod has a first threaded part and a second threaded part at both ends. The limiting rod is connected to the detachable storage cover through the first threaded part and a buffer-type clamping plate is connected through the second threaded part. The inner end of the limiting rod is connected to the limiting plate, which extends into the sampling test tube and clamps it in the storage cavity.

[0011] In a further preferred embodiment of this application, both parts of the locking device are connected to the detachable storage cover and the water quality measuring instrument by bolts. A sealing strip is provided at the joint between the detachable storage cover and the water quality measuring instrument. The detachable storage cover covers the control panel and provides protection.

[0012] In a further preferred embodiment of this application, the cavity of the receiving cavity is connected with a buffer rubber by an adhesive, the sampling tube is embedded in the cavity of the buffer rubber, the outermost end of the limiting rod is provided with a rotating handle, and the outside of the rotating handle is connected with an anti-slip rubber sleeve by an adhesive.

[0013] In a further preferred embodiment of this application, the buffer-type clamping disc is divided into a "T"-shaped sleeve and a buffer-type sealing ring. The buffer-type sealing ring is located on the end face of the "T"-shaped sleeve and faces the opening of the sampling test tube.

[0014] In a further preferred embodiment of this application, the limiting disc is connected to the limiting rod by bolts, and a rubber ring is provided at the connection between the limiting disc and the limiting rod. The limiting disc is designed in a "Y" shape, and water can be discharged or inlet through the gap between the limiting disc and the sampling test tube.

[0015] In a further preferred embodiment of this application, the limiting rod is detached from the detachable storage cover and connected to the sampling tube via a limiting disc. The limiting rod serves as an extension arm for the sampling tube, thereby enabling the sampling operation.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] With its detachable storage cap, the sampling tubes can be neatly stored in the storage chamber, which not only makes it convenient for users to quickly access them, but also prevents the sampling tubes from being scattered or lost, thus improving the convenience and efficiency of the sampling operation.

[0018] The limiting rod and limiting disc ensure the stability of the sampling tube within the storage cavity. The limiting disc extends into the sampling tube, securing it firmly within the storage cavity, effectively preventing shaking and collisions during movement or transport, thus ensuring the sampling tube remains intact.

[0019] The use of cushioning rubber and a cushioning clamping disc further enhances the protection of the sampling tube. The cushioning rubber absorbs external impact forces, reducing damage to the sampling tube; while the cushioning clamping disc effectively prevents external substances from entering the sampling tube, ensuring the purity of the sample tube and the accuracy of the sampling results.

[0020] The device is designed with user convenience and safety in mind. The rotating handle allows users to easily rotate the limiting lever and adjust the position of the sampling tube; while the use of anti-slip rubber sleeves improves the grip comfort and anti-slip effect of the rotating handle, reducing safety risks during operation.
