Description

Technical Field

[0001] This utility model relates to the field of liquid level sensor technology, specifically to a liquid level sensor mounting base. Background Technology

[0002] Because hydrostatic level sensors operate on the principle of hydrostatic pressure, the flow of fluid within a stirred container has minimal impact on their measurement accuracy. Therefore, they are commonly used in various media level measurements across systems and industries such as petrochemicals, metallurgy, power, pharmaceuticals, water supply and drainage, and environmental protection. Since the hydrostatic level sensor is not fixed within the liquid, maintenance only requires lifting the signal cable. However, applying hydrostatic level sensors to stirred containers still presents the following problems: 1. The flowing fluid can impact the hydrostatic level sensor, causing it to collide with the stirring structure; 2. The flowing fluid can impact the signal cable on the hydrostatic level sensor, causing it to twist and move. Twisting can lead to knots, and moving the cable poses a risk of being caught in the stirring structure.

[0003] Some manufacturers provide magnetic mounting bases to attach the hydrostatic level sensor to the bottom inner wall of the mixing container, thus preventing the sensor from being moved by the fluid. However, they do not provide protection or fixing for the signal cable, which is still susceptible to twisting and movement due to fluid impact. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1-5This utility model provides a technical solution: a liquid level sensor mounting base, including a base shell 1 and a base base 2, which are detachably mounted to the base shell 1. The outer wall of the base shell 1 is connected to a liquid inlet 5, and the end of the liquid inlet 5 is connected to a filter assembly 8. A liquid level sensor 3 is installed inside the base shell 1, and a signal cable 4 is connected to the signal end of the liquid level sensor 3. The signal cable 4 extends from inside the base shell 1. A cable guide assembly 7 is provided on the top of the base shell 1, through which the signal cable 4 passes. A magnetic base 6 is bolted to the base shell 1, located below the base base 2. Multiple cable protection assemblies 9 are provided outside the signal cable 4. The base shell 1 and the base base 2 constitute the entire mounting base body, for mounting the liquid level sensor 3. For protection, the liquid level sensor 3 is a hydrostatic immersion type liquid level sensor. A magnetic base 6 is provided to adsorb the base shell 1 onto the bottom inner wall of the stirring container. When the stirring fluid impacts the base shell 1, the magnetic attraction can prevent the base shell 1 from being washed away. A cable protection assembly 9 is provided to protect the signal cable 4, preventing the signal cable 4 from twisting or being caught in the stirring structure when the fluid impacts the signal cable 4. A cable guide assembly 7 is provided to guide the signal cable 4. Together with the cable protection assembly 9, the signal cable 4 is guided to the inner wall of the container, so that the cable protection assembly 9 can better fix the signal cable 4 to the inner wall of the container. A filter assembly 8 is provided to filter the fluid that enters the base shell 1 from the liquid inlet 5, preventing impurities in the fluid from entering the base shell 1 and then clogging the liquid inlet 5. The cable protection assembly 9 includes a high-hardness thermoplastic sheet 901 and a soft magnetic strip 902. The two ends of the high-hardness thermoplastic sheet 901 and the soft magnetic strip 902 are fixedly connected together. A wire-passing hole 903 is provided at the connection point between the soft magnetic strip 902 and the high-hardness thermoplastic sheet 901. The signal cable 4 passes through the wire-passing hole 903. An elastic metal tube 904 is adhered to the soft magnetic strip 902. The elastic metal tubes 904 on adjacent soft magnetic strips 902 are connected together by a detachable connector. The strip 902 is attached to the inner wall of the container to fix the signal cable 4 and prevent the signal cable 4 from being washed away by the fluid. By pinching the high-hardness thermoplastic sheet 901, the high-hardness thermoplastic sheet 901 is deformed, which in turn causes the soft magnetic strip 902 to deform, so that the soft magnetic strip 902 can better fit the inner wall of the container. The elastic metal tube 904 is set to be used to cover multiple cable protection components 9 on the signal cable 4, so that the multiple cable protection components 9 form a whole and improve the impact resistance to the fluid. The magnetic base 6 includes a counterweight 601, which is fixedly connected to the base housing 1 by bolts. A magnet 602 is provided at the bottom of the counterweight 601, and a connecting bolt 603 is fixedly installed at the bottom of the counterweight 601. The connecting bolt 603 passes through the magnet 602, and a nut for fixing the magnet 602 is threaded on the connecting bolt 603. The counterweight 601 is used to increase the weight of the entire mounting base, making it less likely for fluid to wash away the mounting base. The magnet 602 is used to attract to the inner wall of the bottom of the container. The connecting bolt 603 connects the magnet 602 and the counterweight 601, making the magnet 602 detachable. When the magnet 602 loses its magnetism or is damaged, it can be replaced. The cable guiding assembly 7 includes a guide tube 701, a guide seat 702, and a mounting tube 703. The guide seat 702 is fixedly installed on the top of the base housing 1, and the mounting tube 703 is fixedly installed inside the base housing 1. The bottom end of the guide tube 701 extends from the guide seat 702 into the mounting tube 703. An elastic connecting sleeve 704 is fixedly connected to the bottom end of the guide tube 701. The bottom end of the elastic connecting sleeve 704 is fixedly connected to the bottom inner wall of the mounting tube 703. A silicone sleeve 705 is fixedly installed on the inner wall of the guide seat 702, and the silicone sleeve 705 is fixedly sleeved on the guide tube 701. The signal cable 4 passes through the mounting tube 703, the elastic connecting sleeve 704, and the guide tube 701 in sequence. The elastic connecting sleeve 704 is set to limit the guide tube 701 in the axial direction, so that the guide tube 701 can swing at a certain angle to guide the signal cable 4, but it cannot detach from the mounting tube 703 and the guide seat 702. The silicone sleeve 705 is set to limit the guide tube 701 in the radial direction, so that the guide tube 701 can squeeze the silicone sleeve 705 when swinging, causing the silicone sleeve 705 to deform, but it cannot detach from the guide seat 702. The filter assembly 8 includes a connecting seat 801, which is connected to the liquid inlet 5 via a detachable connector. A pre-filter plate 802 and a post-filter plate 803 are fixedly installed inside the connecting seat 801. The post-filter plate 803 is located between the pre-filter plate 802 and the liquid inlet 5. The connecting seat 801 is provided for installing the pre-filter plate 802 and the post-filter plate 803. When the fluid flows through the pre-filter plate 802, it is initially filtered to remove larger impurities. Then, it undergoes secondary filtration through the post-filter plate 803 to further remove impurities from the fluid. A through groove 604 is provided on the part of the magnet 602 through which the connecting bolt 603 passes. The lowest point of the connecting bolt 603 is parallel to the lowest point of the magnet 602. The inner diameter of the through groove 604 is larger than the outer diameter of the nut that fixes the connecting bolt 603, so that the connecting bolt 603 and the nut on the connecting bolt 603 will not prevent the magnet 602 from adsorbing onto the inner wall of the container.

[0016] Working principle: In use, the liquid level sensor 3 is installed inside the base housing 1. The signal cable 4 is passed through the mounting tube 703, the elastic connecting sleeve 704, and the guide tube 701. Then, the signal cable 4 is passed through the wire hole 903, and the base base 2 is closed. Then, the counterweight 601 is fixedly connected to the base housing 1 with bolts. Pull the signal cable 4 to place the entire mounting base into the container until the magnet 602 contacts the inner wall of the bottom of the container and then adheres to the inner wall of the container. According to the shape of the inner wall of the container, the high-hardness thermoplastic sheet 901 is squeezed to deform, which in turn causes the soft magnetic strip 902 to deform, so that the soft magnetic strip 902 can better fit the inner wall of the container and then adhere to the inner wall of the container. This completes the installation of the liquid level sensor 3 and the signal cable 4.

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
