Technical Field

[0001] This utility model relates to the field of water quality testing equipment technology, and in particular to a low-temperature sealed multi-parameter water quality probe. Background Technology

[0002] Water quality testing is a process of systematically analyzing physical, chemical, and microbiological indicators in water bodies using scientific methods to assess water safety and suitability. Its core objective is to ensure drinking water safety, ecological balance, and industrial and agricultural water needs. The purpose of water quality testing is to provide a basis for controlling water treatment processes, ensuring that the treated water meets the expected requirements and prescribed water quality standards, and to monitor the operating status of water treatment equipment. Water quality probes are sensors used to detect specific parameters in water bodies, and monitor water quality indicators in real time through physical or chemical methods.

[0003] The existing technical solutions mentioned above have the following drawbacks: the existing water quality probes themselves lack a protective structure, and the external structure is easily damaged, making it impossible to conduct water quality detection and affecting work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature sealed multi-parameter water quality probe.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A low-temperature sealed multi-parameter water quality probe includes a protective shell. One side of the inner side of the protective shell is provided with a first internal thread, and one end of the outer side of the protective shell is provided with a second external thread. A limiting block is fixedly connected to the inner side of the protective shell. A sealing ring is installed inside the limiting block. A through hole is opened inside the sealing ring, and a sealing groove is reserved on the outer side of the sealing ring.

[0007] By adopting the above technical solution, a protective shell and a protective sleeve are added to the outside of the probe. The probe can be protected by the combination of the protective sleeve and the protective shell. At the same time, the two sets of structures can be spliced ​​and installed for easy operation. This does not affect the normal use of the probe and can achieve the protection function.

[0008] Furthermore, a probe body is inserted into the inside of the protective shell, a locking cover is installed on the outside of the protective shell, a first external thread is provided on the outside of the locking cover, a wiring groove is opened in the center inside the locking cover, a protective sleeve is installed on the outside of the protective shell, a water channel is reserved on the outside of the protective sleeve, and a second internal thread is provided inside the protective sleeve.

[0009] By adopting the above technical solution, the components can be connected and installed by threads, which is convenient and quick.

[0010] Furthermore, the locking cover engages inside the protective shell, the first internal thread and the first external thread are threaded together, the sealing groove and the limiting block engage, and one end of the probe body extends through the sealing ring to the outside of the protective shell.

[0011] By adopting the above technical solution and adding a sealing ring, the protective shell and the protective sleeve are sealed together.

[0012] Furthermore, the protective sleeve is fitted onto the outside of the protective shell, and the second external thread and the second internal thread are threaded together. Multiple water channels are evenly spaced and distributed in a ring.

[0013] By adopting the above technical solution, it is easier and more convenient to conduct testing.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] A protective shell and sleeve are used. A protective shell and sleeve are added to the outside of the probe. The probe is directly inserted into the inside of the protective shell. Then, the locking cover is installed, and the protective sleeve is installed on the outside of the protective shell to protect the part detected by the probe. At the same time, the components are installed by threads, which is convenient and quick. The overall structure can protect the probe without affecting its normal use, resulting in convenient installation and use as well as protection. Attached Figure Description
