Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains. The terms “first,” “second,” and similar terms used in the specification and claims of this patent application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an” or “a,” and similar terms, do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0022] like Figure 1 As shown, this utility model provides a water level electrode, which includes an electrode core 10 located at the center and disposed inside an insulating conduit 20. Starting from one end of the electrode core, a hexagonal cap 30, a fastening screw 40, and an outer insulating tube 50 are sequentially fitted around the insulating conduit 20. The end of the fastening screw 40 connected to the outer insulating tube 50 is provided with at least one self-tapping groove 41. When the entire water level electrode body is installed into the mounting hole, foreign objects in the mounting hole can be cleaned through the self-tapping groove 41. If there are many foreign objects, the water level electrode can be repeatedly screwed in and out to ensure that the foreign objects in the mounting hole are cleaned and the water level electrode can be installed smoothly. This overcomes the problem in the prior art where the water level electrode cannot be installed due to the mounting hole being blocked by foreign objects.

[0023] In this embodiment, a water level electrode includes an electrode core 10 at its center and a hexagonal cap 30 and a fastening screw 40 arranged sequentially along one end of the electrode core 10. The electrode core 10 is wrapped with an insulating conduit 20, and the upper end of the insulating conduit 20 is fixedly sleeved with the hexagonal cap 30. The upper end of the fastening screw 40 is connected to the hexagonal cap 30. An outer insulating tube 50 is sleeved around the insulating conduit 20 below the fastening screw 40. At least one self-tapping groove 41 is formed at the end of the fastening screw 40 near the outer insulating tube 50. The self-tapping groove 41 is a U-shaped groove formed by the inward indentation of the fastening screw 40, with the opening of the U-shaped groove facing the outer insulating tube 50 and protruding from the surface of the outer insulating tube 50.

[0024] Specifically, the end of the fastening screw 40 near the outer insulating tube 50 is provided with three self-tapping grooves 41 evenly spaced along its end, forming a self-tapping section of the fastening screw 40. The self-tapping grooves 41 protrude from the surface of the outer insulating tube 50 and open outward, acting as a scraper. When the water level electrode is screwed in for installation, the self-tapping grooves 41 can scrape away impurities and foreign objects adsorbed in the installation hole.

[0025] Specifically, a nut and a washer are provided between the hexagonal cap 30 and the insulating conduit 20. The nut is placed on the washer to secure the hexagonal cap 30 under the washer.

[0026] Specifically, both the insulating conduit 20 and the outer insulating tube 50 can be made of polytetrafluoroethylene (PTFE). PTFE has good waterproof sealing, good insulation, and good toughness. It can use domestically produced new materials or imported materials and can withstand temperatures above 200℃.

[0027] Specifically, the hexagonal cap 30 is made of steel or stainless steel, and the electrode core 10 and the fastening screw 40 are made of metal, or can be made of steel or stainless steel.

[0028] Specifically, the hexagonal cap 30 has an internal thread on its inner side, and the fastening screw 40 has an external thread on its outer side at one end. The internal thread and the external thread are compatible, and the hexagonal cap 30 and the fastening screw 40 are connected by threads.

[0029] Specifically, the end of the electrode core 10 of the water level electrode is inserted through and extends out of the insulating conduit 20 to facilitate water level testing.

[0030] The working principle of this embodiment is as follows: The water level electrode may be damaged during use and needs to be replaced. The water used in industrial or domestic processes has a complex composition and may contain impurities, scale and other foreign objects. During the disassembly of the water level electrode, foreign objects may be introduced into the mounting hole, making it difficult to install the water level electrode. The self-tapping water level electrode has a self-tapping groove 41, which can clean the foreign objects in the mounting hole. When there are many foreign objects, the self-tapping water level electrode can be screwed in and out repeatedly to ensure that the foreign objects in the mounting hole are cleaned and the water level electrode can be installed smoothly.

[0031] In summary, the technical solution of this application has the following beneficial effects:

[0032] 1. The advantages of this utility model are that it has a reasonable structure and good sealing performance. By setting grooves, it can effectively prevent impurities in the water from adhering to and clogging the mounting holes of the water level electrode, which facilitates the replacement and maintenance of the water level electrode, improves work efficiency, and is safe and reliable to use.

[0033] 2. Compared with traditional water level electrodes, the water level electrode of this application can solve the problem of installation holes being clogged by impurities, scale, and other debris, eliminating the need for manpower and resources to install the water level electrode. Maintenance and installation are convenient and cost-effective, thus accurately detecting water levels and ensuring the safe and stable operation of industrial and domestic water supply. Furthermore, this utility model has a simple structure, high versatility, and is suitable for standardized large-scale production.

[0034] The above are merely exemplary embodiments of this application and are not intended to limit the scope of protection of this application, which is determined by the appended claims.
