Description

Technical Field

[0001] The utility model relates to the technical field of oxygen analyzers, in particular to an oxygen analyzer with convenient probe replacement. Background Art

[0002] In industrial environments, such as chemical plants, mines, oil drilling platforms, etc., monitoring oxygen concentration is crucial to ensure the safety of workers. Oxygen analyzers can monitor the oxygen level in the environment to prevent hypoxia or excess oxygen, which may lead to casualties or safety accidents such as fire and explosion.

[0003] After searching, a Chinese patent discloses a universal oxygen analyzer (authorization announcement number CN212808194U) including a main body, a pipeline storage mechanism is provided on the lower end outer surface of the main body, a device housing is provided on the upper end outer surface of the pipeline storage mechanism, a control panel is provided on the front end outer surface of the device housing, and handles are provided on both sides of the outer surface of the device housing. Although the above patent technology can store the pipes used for equipment analysis through the winding rod, the pipes can also be inserted into the fixing grooves provided on the fixing plate for fixing to prevent the pipes from being dragged to the ground due to excessive length and causing damage to the pipes. The provided pipeline storage mechanism can place the pipes and power cords used by the equipment into the storage box after the equipment is used to prevent the loss of the pipes and power cords from affecting the use of the equipment, bringing about a better use prospect;

[0004] However, in the actual application of this patented technology, the sensor probe of the oxygen analyzer cannot be quickly replaced during use, resulting in the entire oxygen analysis system being shut down when the probe is damaged or needs repair until the probe is repaired or replaced. During this period, the oxygen concentration cannot be monitored, posing a potential safety risk. Utility Model Content

On the opposite side of each sensor probe 2, there is a sliding groove 3 in the protective shell 1, and a sliding plate 4 is slidably connected in the sliding groove 3. A pull rod 5 is fixed in the sliding plate 4. The two ends of the spring 9 are respectively connected to the pull rod 5 and the inner wall of the sliding groove 3, thereby ensuring the reset function of the pull rod 5.

Through the designed limiting structure, the sensor probe 2 can be accurately fixed and quickly released, which is convenient for replacement.

[0034] Among them, a placement groove 10 is opened inside the protective shell 1, and the oxygen analyzer body 11 is fixedly connected inside the placement groove 10.

[0039] Working principle:

[0040] like Figure 1-Figure 6As shown, when the above device is in use, the entire device is first installed and fixed by the mounting plate 20. When the sensor probe 2 fails, the staff pulls the pull rod 5 to both sides so that the ends of the two pull rods 5 that are close to each other are separated from the limit groove 6 of the sensor probe 2, and the second limit blocks 8 are respectively pressed on the outside of the first limit blocks 7, so that the pull rod 5 will not be reset by the spring 9. When the sensor probe 2 is replaced, the pull rod 5 is rotated to make the first limit block 7 and the second limit block 8 misaligned, so that the ends of the two pull rods 5 that are close to each other limit the sensor probe 2. The sensor probe 2 transmits data to the oxygen analyzer body 11 through the contact between the second contact block 14 and the first contact block 13, so as to analyze and detect oxygen. Finally, the data is transmitted to the terminal through the wireless signal transceiver 19. The maintenance and replacement of the system can be carried out quickly, which reduces the downtime of the entire oxygen analysis system and greatly improves the operation quality and use efficiency compared with traditional devices.
