Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, and in particular to an immersion hydrostatic liquid level gauge with self-cleaning function. Background Technology

[0002] Submersible hydrostatic level gauges are instruments that monitor liquid level based on the principle of hydrostatic measurement. They are widely used in industrial production, water conservancy projects, environmental monitoring and other fields.

[0003] However, in the existing technology, the existing submersible hydrostatic level gauges are widely used for monitoring in various water bodies. However, since most water bodies contain different impurities, in some areas with severe water pollution, the water inlet of the probe can be blocked in a short time. Therefore, some existing submersible hydrostatic level gauges use a cover filter on the probe surface to prevent impurities from clogging it. However, as long as it is used for a long time, a large amount of impurities will accumulate on the cover filter, affecting the filtration effect of the cover filter. This requires regular manual cleaning, increasing the cost of use and making it less convenient for users. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] like Figure 1 - Figure 5As shown, this utility model provides a technical solution: a submersible hydrostatic level gauge with self-cleaning function, comprising: a level gauge body 1, a main guide line 2 at the bottom of the level gauge body 1, and a probe body 3 at the end of the main guide line 2 away from the level gauge body 1. The probe body 3 is characterized by having a self-cleaning mechanism 4 on its outer side, a locking mechanism 5 at one end of the self-cleaning mechanism 4, and the self-cleaning mechanism 4 including a threaded protective shell 41. The threaded protective shell 41 enhances the fixation between the self-cleaning mechanism 4 and the probe body 3 through a threaded connection. An anti-clogging plate 42 is provided inside the threaded protective shell 41, which effectively filters impurities in the water, thereby preventing damage to the probe. To prevent interference and blockage, a permanent magnet suction plate 43 is provided on one side of the anti-blockage plate 42. An electromagnet core cleaning component 401 is provided on the side of the anti-blockage plate 42 away from the permanent magnet suction plate 43. A permanent magnet suction plate 49 is provided on the side of the electromagnet core cleaning component 401 away from the anti-blockage plate 42. A wire protection tube 44 is provided at one end of the outer side of the permanent magnet suction plate 43. The wire protection tube 44 can protect the wires passing through it, thus extending the service life and safety of the wires. A flexible wire 48 is provided at the other end of the wire protection tube 44 away from the permanent magnet suction plate 43. Limiting sliders 45 are provided at the four corners of the outer side of the electromagnet core cleaning component 401. Limiting sliders 45 are provided on the outer side of the limiting sliders 45. The rail 46, through the limiting sliding effect between the installed limiting slider 45 and the limiting rail 46, can better limit the electromagnetic core cleaning component 401, ensuring its vertical sliding guidance. A return spring 47 is provided at one end of the limiting slider 45, which facilitates the reset of the electromagnetic core cleaning component, preventing the electromagnetic core cleaning component 401 from blocking the anti-blocking plate 42. The interior of one end of the threaded protective shell 41 is threadedly fixedly connected to the exterior of one end of the probe body 3. The exterior of the anti-blocking plate 42 and the exterior of the first permanent magnet suction plate 43 are both fixedly connected to the interior of the threaded protective shell 41. The exterior of the second permanent magnet suction plate 49 is fixedly connected to the interior of the threaded protective shell 41. Flexible guide... One end of the wire 48 away from the wire protection tube 44 is fixedly connected to one side of the probe body 3. One side of the permanent magnet suction plate 43 and one side of the permanent magnet suction plate 49 are both fixedly connected to the outside of the wire protection tube 44, so as to better conduct the wire and protect it. One end of the wire protection tube 44 away from the permanent magnet suction plate 43 is fixedly connected to one end of the flexible wire 48. One end of the four limit sliders 45 is fixedly connected to the four corners of the electromagnet core cleaning component 401 at equal intervals. The outside of the limit sliders 45 is slidably connected to the inside of the limit slide rail 46. One end of the limit sliders 45 is fixedly connected to one end of the reset spring 47. The end of the reset spring 47 away from the limit sliders 45 is fixedly connected to the inside of one end of the limit slide rail 46.

[0026] It should be noted that both permanent magnet suction plate 1 (43) and permanent magnet suction plate 2 (49) are made of neodymium iron boron permanent magnets, and are arranged in multiple circular structures. These circular structures are connected in series via annular connecting tubes, linking multiple circular neodymium iron boron permanent magnet structures together. These circular structures are then connected in parallel by wires, which are then placed inside wire protection tubes (44) for protection. Finally, the wires (flexible wires (48)) are electrically connected to the probe body 3 to further enhance the protection of the wires. It should also be noted that the side of permanent magnet suction plate 1 (43) closest to the anti-blocking plate 42 has magnetic attraction, while the side of permanent magnet suction plate 2 (49) closest to the electromagnet core cleaning component 401 has repulsive force, thus better cleaning the electromagnet core. The cleaning component 401 provides the power to move towards the anti-blocking plate 42, thereby achieving a cleaning effect using the electromagnet core cleaning component 401. It should be noted that the electromagnet core cleaning component 401 is made of silicon steel or permalloy electromagnet core. Due to the characteristics of its material, such as high magnetic permeability, low coercivity, rapid magnetization after energization, and no residual magnetism when de-energized, the side of the electromagnet core cleaning component 401 near the anti-blocking plate 42 is set as the repulsive surface, and the side near the permanent magnet suction plate 49 is set as the magnetic attraction surface. This achieves the effect of opposite poles attracting and like poles repelling with the first permanent magnet suction plate 43 and the second permanent magnet suction plate 49. Thus, the magnetic force provides the power source for the electromagnet core cleaning component 401. Furthermore, due to its material properties, the characteristic of no residual magnetism when de-energized makes it easier for the electromagnet core cleaning component 401 to achieve a reset effect, thereby making it easier for users to use. Example 2

[0027] like Figure 1 - Figure 5 As shown, the locking mechanism 5 includes a fixed sleeve 51, inside which a spring limiting member 52 is provided. Limiting clips 53 are provided at both ends of the outer side of the spring limiting member 52. The spring limiting member 52 is slidably limited to both sides inside the fixed sleeve 51 via the limiting clips 53. One side of the top of the fixed sleeve 51 is fixedly connected to the outer side of one end of 4. The top of the spring limiting member 52 is fixedly connected to the top of the inside of the fixed sleeve 51, thereby increasing the fixing effect between the spring limiting member 52 and the fixed sleeve 51. The limiting clips 53 at both ends of the outer side of the spring limiting member 52 facilitate vertical sliding of the spring limiting member 52, ensuring its stable limiting function. It should be noted that the probe body 3 has corresponding limiting grooves, which further facilitates the locking mechanism 5 in limiting the probe body 3.

[0028] Working principle: Since the probe body 3 of the submersible hydrostatic level gauge is equipped with a water inlet hole to better detect the water level, the water may become clogged due to impurities in the water. The anti-clogging plate 42 installed inside the self-cleaning mechanism can better filter the water and prevent clogging of the water inlet hole. The electromagnet core cleaning component 401 can better clean the anti-clogging plate 42, ensuring that the filtering effect of the anti-clogging plate 42 is not affected, thus better ensuring the operation of the probe body 3 and better avoiding affecting the detection results.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
