Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to an electrode sheath structure for installing a pH electrode in a pipeline. Background Art

[0002] In today's pH measurement environments, it's common to insert a pH electrode directly into a pipe. Electrode sheaths are used for pipe-mounted pH electrodes and are typically made of corrosion-resistant materials such as plastic or metal to protect the electrode from chemicals and physical damage. They typically consist of a housing that fits within the pipe, a device to secure the electrode, and components such as gaskets or clamps for securing and sealing. The sheath's design ensures the electrode remains stably positioned, preventing leaks while allowing fluid to pass through for accurate pH measurements.

[0003] An electrode sheath structure for a pipeline-mounted pH electrode disclosed in Chinese patent publication number CN207675688U employs an oblique design on a straight pipe. This structure not only reduces the water flow velocity near the electrode, thereby reducing the generation of streaming potential and making the measurement more stable, but also prevents particles from directly impacting the electrode and reduces the movement speed of particles, thereby reducing physical damage to the electrode when particulate matter is present. It also prevents the generation of stagnant water in the straight pipe, ensuring timely and effective measurements. However, the overall flexibility of the electrode sheath structure is low, and the flow rate and flow velocity of the fluid cannot be effectively adjusted, thereby affecting the stability and accuracy of subsequent pH electrode measurements. Utility Model Content

[0004] The purpose of the utility model is to provide an electrode sheath structure for installing a pH electrode in a pipeline, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an electrode sheath structure for installing a pH electrode in a pipeline, comprising a pipeline body, a connecting disk installed on one side of the top of the pipeline body, a connecting seat installed on the top of the connecting disk, mounting mechanisms evenly arranged at equal distances inside the connecting seat, a protective sleeve rotatably connected to the middle position inside the connecting seat, a positioning mechanism provided on one side inside the top of the protective sleeve, a rotating shaft rotatably connected to the middle position inside the top of the protective sleeve, and a connector connected to the internal thread of the rotating shaft.

[0006] Preferably, the mounting mechanism includes screw grooves evenly spaced inside the top of the connecting plate, a rotating rod slidably connected to one side of the top of the connecting seat, and a cross block fixedly connected to the bottom end of the rotating rod.

[0007] Preferably, a turntable is provided on the outside of the cross block, and a bolt threadedly connected to the screw groove is fixedly connected to the middle position of the bottom end of the turntable.

[0008] Preferably, the positioning mechanism includes positioning holes evenly spaced at the top of the connecting seat, a pull rod is slidably connected to the inside of the top of the protective cover, and a movable block is fixedly connected to the bottom end of the pull rod.

[0009] Preferably, a spring is fixedly connected to the top end of the movable block, and a positioning rod that is inserted into the positioning hole is fixedly connected to the middle position of the bottom end of the movable block.

[0010] Preferably, a pH electrode head is fixedly connected to the middle position of the bottom end of the connecting head.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This electrode sheath structure for pipeline-mounted pH electrodes effectively reduces the flow rate of water by providing a protective sheath on the outside of the pH electrode head. At the same time, the protective sheath is fixed in position by inserting a positioning rod inside the protective sheath into a positioning hole on the connecting seat. When the positioning rod inside the protective sheath is withdrawn from the positioning hole on the connecting seat, the protective sheath can be rotated. At this time, by rotating the protective sheath to different angles within the pipeline body, the pH electrode head can be effectively adjusted to contact the fluid flow rate and direction within the pipeline body, thereby optimizing the electrode contact effect and being adjustable according to different fluid conditions to ensure more accurate measurements.

[0013] 2. This electrode sheath structure for pipeline-mounted pH electrodes has a rotating rod provided inside the top of the connecting seat. When the cross block at the bottom of the rotating rod is inserted into the turntable in the connecting seat, the rotating rod can drive the bolt to rotate through the turntable, and the bolt is rotated into the screw groove at the top of the connecting plate, thereby completing the quick connection and assembly between the connecting plate and the connecting seat. After use, the rotating rod can be pulled out from the inside of the connecting seat to prevent the subsequent loose connection due to accidental touch. The operation is simple and convenient, which improves the convenience of disassembly and assembly of the electrode sheath structure and the overall stability after connection.
