Description

Technical Field

[0001] This utility model relates to the field of turbidity detection technology, specifically to a replaceable probe-type turbidity detection component. Background Technology

[0002] In fields such as water quality monitoring, industrial production process control, and environmental protection testing, turbidity detection is an important step in assessing the transparency and impurity content of liquids. Turbidity detection equipment acquires turbidity data of liquids through probes.

[0003] However, during long-term use, contaminants easily accumulate on the probe surface or cause wear and tear, requiring regular replacement or maintenance. Ordinary turbidity detection components generally suffer from the problem of inconvenient probe replacement. Their installation structure usually adopts a fixed connection, which leads to a lot of time and effort required for disassembly. Furthermore, improper operation may cause water ingress or short circuits, affecting the normal operation of the detection equipment. Existing replaceable probe structures often rely on fixed lines or plug-in interfaces for electrical connection. The former cannot meet the independent replacement needs of the probe, while the latter may cause misalignment of conductive contacts due to the relative rotation of the probe and the positioning structure during installation, resulting in signal transmission interruption or increased contact resistance. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

This embodiment improves the structure of the turbidity detection component to give it the advantages of rapid replacement and positioning. Specifically, taking the replacement of the turbidity detection probe as an example, as a preferred solution in this embodiment, the turbidity detection component is a replaceable probe type turbidity detection component, enabling rapid probe replacement.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a replaceable probe turbidity detection component, which is mainly used in scenarios where the probe needs to be replaced due to the adhesion of pollutants after long-term use.

[0025] The device includes a positioning cylinder 1, with a positioning shaft 3 fixedly connected to the other end of the positioning cylinder 1. The outer surface of the positioning shaft 3 has multiple guide grooves 4. The inner sidewall of the guide groove 4 is slidably connected to a limit block 5. The end of the positioning shaft 3 is fixedly connected to a positioning post 7. The end of the positioning post 7 is fixedly connected to a conductive contact 8. The outer surface of the positioning shaft 3 is rotatably connected to a threaded sleeve 9. The inner wall of the threaded sleeve 9 has a limit groove 10. The inner wall of the limit groove 10 is engaged with the outer surface of the limit block 5. The outer wall of the threaded sleeve 9 is threadedly connected to a probe 11.

[0026] In this embodiment, the positioning cylinder 1 serves as the main support structure of the component. One end is connected to an external detection device or line, and the other end is fixed to the positioning shaft 3, providing an installation reference for the entire detection component. By fixing the positioning shaft 3 and the wire 2, the stability of the internal electrical connection is ensured, and a positioning base is provided for the installation of the probe 11, avoiding the overall shaking of the component from affecting the detection accuracy. The positioning shaft 3 is fixed to the end of the positioning cylinder 1, and multiple guide grooves 4 are opened on the outer surface for the sliding guidance of the limiting block 5. The guide groove 4 restricts the movement direction of the limiting block 5, allowing it to slide only axially, thus providing support for the axial positioning of the threaded sleeve 9. It also ensures that the limiting block 5 does not disengage from the positioning shaft 3 when the threaded sleeve 9 rotates. The positioning post 7 is fixed to the end of the positioning shaft 3, passes through the threaded sleeve 9, and inserts into the inner wall of the probe 11, serving as a mechanical positioning structure. The conductive contact 8 is fixed to the end of the positioning post 7, and its outer wall contacts the conductive components on the inner wall of the probe 11, achieving electrical connection. The positioning post 7 ensures the coaxiality of the probe 11 and the positioning shaft 3, preventing the probe 11 from shifting during installation. The conductive contact 8, through contact with the internal circuitry of the probe 11, transmits the detection signal to external devices via the wire 2, ensuring the stability of signal transmission. When the probe 11 is installed in place, the conductive contact 8 precisely aligns with the internal contacts of the probe 11, preventing contact misalignment due to relative rotation. The inner wall of the threaded sleeve 9 has a limiting groove 10 that engages with the limiting block 5, and its outer wall has an external thread that connects to the internal thread of the probe 11. The limiting groove 10 runs circumferentially along the inner wall of the threaded sleeve 9. The extension allows the threaded sleeve 9 to rotate on the positioning shaft 3, but restricts its axial movement. During installation, rotating the threaded sleeve 9 fixes the probe 11 to the positioning shaft 3 via the threads. Simultaneously, the engagement between the limiting block 5 and the limiting groove 10 ensures that the threaded sleeve 9 will not move axially during rotation, preventing relative rotation between the probe 11 and the positioning shaft 3 during installation and ensuring precise contact between the conductive contact 8 and the probe 11. During disassembly, rotating the threaded sleeve 9 in the opposite direction causes the limiting block 5 to slide along the limiting groove 10. Once the threads are fully released, the limiting block 5 disengages from the limiting groove 10, allowing the probe 11 to be removed. The operation is convenient. The front end of the probe 11 is a turbidity detection sensing end with an integrated detection circuit. It connects to the threaded sleeve 9 via internal threads, and the inner wall has conductive components that contact the conductive contact 8. As the core component for turbidity detection, it collects liquid turbidity data and transmits signals through the conductive contact 8. The detachable design allows the probe 11 to be replaced individually, solving the problem of requiring complete disassembly after probe 11 contamination or wear in existing technologies, thus reducing maintenance costs.

[0027] In the above embodiment, as a preferred solution, a wire 2 is fixedly installed at one end of the positioning cylinder 1. The wire 2 is electrically connected to the conductive contact 8. One end of the wire 2 is connected to the external detection circuit, and the other end is electrically connected to the conductive contact 8 at the end of the positioning column 7 to transmit the turbidity detection signal, realize the real-time transmission of the detection signal, and ensure that the turbidity data collected by the probe 11 can be stably transmitted to the external device to avoid signal interruption.

[0028] In the above embodiment, as a preferred solution, a compression spring 6 is fixedly connected to the bottom of the limiting block 5, and the other end of the compression spring 6 is fixedly connected to the inner bottom wall of the guide groove 4. The limiting block 5 is slidably installed in the guide groove 4, and the bottom is connected to the inner bottom wall of the guide groove 4 through the compression spring 6. The upper end is inserted into the limiting groove 10 of the inner wall of the threaded sleeve 9. The compression spring 6 provides an upward elastic force, so that the limiting block 5 always remains in the locking state with the limiting groove 10. When the threaded sleeve 9 is fitted on the positioning shaft 3, the limiting block 5 is locked into the limiting groove 10 under the action of the compression spring 6, restricting the axial movement of the threaded sleeve 9, ensuring that the relative position of the threaded sleeve 9 and the positioning shaft 3 is fixed, and avoiding axial movement of the threaded sleeve 9 when the probe 11 is installed.

[0029] In the above embodiments, as a preferred option, one end of the positioning post 7 protruding from the threaded sleeve 9 is inserted into the inner wall of the probe 11, and the outer wall of the conductive contact 8 is electrically connected to the inner wall of the probe 11.

[0030] In the above embodiment, as a preferred solution, guide rods 12 are fixedly connected to both sides of the outer surface of the probe 11, and guide seats 13 are fixedly connected to both sides of the outer surface of the positioning cylinder 1. The outer surface of the guide rods 12 is inserted into the inner wall of the guide seats 13. The guide rods 12 on both sides of the probe 11 are inserted into the guide seats 13 on both sides of the positioning cylinder 1. The inner wall of the guide seat 13 has a straight groove structure, which restricts the movement direction of the guide rods 12. When the probe 11 is installed, the guide rods 12 cooperate with the guide seats 13 to prevent the probe 11 from circumferentially shifting as the threaded sleeve 9 rotates, ensuring that the conductive contact 8 is precisely aligned with the axis of the internal contact of the probe 11, and avoiding contact misalignment or poor contact caused by rotation.

[0031] In the above embodiments, as a preferred option, the end of the threaded sleeve 9 is detachably connected to a first sealing ring 14, and the outer surfaces of both the threaded sleeve 9 and the positioning shaft 3 are fitted with second sealing rings 15. The first sealing ring 14 is installed on the end of the threaded sleeve 9 and forms an end face seal when it contacts the probe 11. The second sealing rings 15 are respectively fitted on the outer surfaces of the threaded sleeve 9 and the positioning shaft 3 to form a radial seal. The double sealing structure prevents liquid from seeping into the interior of the component, avoids short circuits or circuit damage caused by water ingress, and improves the waterproof performance and service life of the component.

[0032] In this invention, the working steps of the device are as follows:

[0033] When it is necessary to replace probe 11, first insert guide rod 12 into guide seat 13, rotate threaded sleeve 9 to move probe 11 and positioning shaft 3, thereby causing positioning post 7 to drive conductive contact 8 into probe 11, thus connecting positioning cylinder 1 and probe 11, and completing the installation of probe 11. When it is necessary to disassemble probe 11, rotate threaded sleeve 9 in the opposite direction to move probe 11 and positioning shaft 3 in the opposite direction until probe 11 and threaded sleeve 9 are separated, thus completing the disassembly of probe 11.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
