Description

Technical Field

[0001] This utility model belongs to the field of liquid level gauge technology, and in particular relates to a magnetic float liquid level gauge. Background Technology

[0002] Level gauges are essential devices for measuring the liquid level within containers. Traditional glass plate or tube level gauges directly mount the glass plate or tube onto the container to visually display the liquid level. However, this traditional method has some drawbacks: the glass plate or tube is susceptible to external factors such as liquid splashing and corrosion, which can reduce its transparency and affect the observation results. Compared to traditional glass plate level gauges, magnetic float level gauges (also known as magnetic tilt level gauges) offer significant advantages in liquid level observation. Magnetic float level gauges isolate the display section from the medium, preventing malfunction due to contamination and resulting in more accurate readings. Furthermore, these gauges can display the liquid level locally without a power source, greatly improving ease of use and safety.

[0003] A special type of magnetic float level gauge is used in existing high-temperature and high-pressure environments. This type of gauge uses a magnetic float and a magnetic flap to indicate the liquid level in a container. However, in practical applications, replacing these components becomes extremely difficult when the magnetic flap indicator is damaged. Traditional maintenance methods typically involve stopping the production process, disassembling the entire equipment, and then performing complex and time-consuming repairs. This approach not only consumes a significant amount of time and reduces production efficiency but also increases maintenance costs. Especially in high-temperature and high-pressure environments, the disassembly and assembly of the equipment requires special protective measures, making the operation difficult and posing high safety risks.

[0005] To achieve the above objectives, this utility model provides a magnetic float level gauge, comprising: A measuring main float is used to connect with an external container to form a communicating vessel, so that the liquid level in the measuring main float is consistent with the liquid level in the external container. A magnetic float is installed inside the main measuring buoy and can rise and fall synchronously with the rise and fall of the liquid level inside the main measuring buoy. A magnetic flap indicator, located outside the main measuring float, is used to indicate the liquid level in response to the rise and fall of the magnetic float via magnetic coupling; and A detachable connection assembly connects the measuring main float and the magnetic flap indicator, enabling the magnetic flap indicator to be separated from or assembled with the measuring main float without disassembling the measuring main float.

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figures 1-5 As shown, a magnetic float level gauge is provided, comprising: A measuring main float is used to connect with an external container to form a communicating vessel, so that the liquid level in the measuring main float is consistent with the liquid level in the external container. A magnetic float is installed inside the main measuring buoy and can rise and fall synchronously with the rise and fall of the liquid level inside the main measuring buoy. A magnetic flap indicator, located outside the main measuring float, is used to indicate the liquid level in response to the rise and fall of the magnetic float via magnetic coupling; and A detachable connection assembly connects the measuring main float and the magnetic flap indicator, enabling the magnetic flap indicator to be separated from or assembled with the measuring main float without disassembling the measuring main float.

[0029] Specifically, the magnetic float level gauge of this utility model detachably connects the magnetic flap indicator to the measuring main float via a detachable connection assembly. When the magnetic flap indicator is damaged and needs to be replaced, the operator does not need to disassemble the measuring main float (the measuring main float is always in communication with the external container and does not need to stop production). The magnetic flap indicator can be separated from the outside of the measuring main float simply by using the detachable connection assembly. After replacing the magnetic flap indicator, reassemble it back onto the outside of the main measuring buoy using the detachable connection assembly, so that the magnetic flap indicator re-establishes magnetic coupling with the magnetic float inside the main measuring buoy (when the magnetic float rises and falls with the liquid level inside the main measuring buoy, the magnetic flap indicator synchronously indicates the liquid level through magnetic coupling). This structural design effectively solves the problem of having to stop production and disassemble the entire device for replacement when the magnetic flap indicator of a magnetic float level gauge is damaged under high temperature and high pressure conditions. It does not require interrupting the production process and significantly improves production efficiency. At the same time, it avoids the complex operation of disassembling and assembling the main float under high temperature and high pressure conditions, reduces the difficulty of maintenance and safety risks, and reduces maintenance time and costs.

[0030] In another embodiment of this utility model, such as Figures 1-5 As shown, the detachable connection assembly is a bolted connection structure, which includes connecting lugs and mounting holes. The connecting lugs are spaced apart along the length of the main measuring float on the outer wall of the main measuring float. The mounting holes are located at the edge of the magnetic flip indicator, and the positions of the mounting holes correspond one-to-one with the positions of the connecting lugs. Specifically, using a bolted connection structure as the detachable connection assembly is simple and mature, with high connection strength and good stability. This ensures a stable connection between the magnetic flip indicator and the main measuring float, preventing loosening during long-term use or under vibration, and guaranteeing the accuracy of the liquid level indication. Simultaneously, the spaced connecting lugs along the length of the main measuring float ensure uniform stress on the magnetic flip indicator during installation, further improving connection reliability. The one-to-one correspondence between the mounting holes and the connecting lugs facilitates quick alignment and installation, simplifying the assembly process.

[0031] In another embodiment of this utility model, such as Figures 1-5 As shown, it also includes a positioning component, which includes a positioning pin and a positioning hole. The positioning pin is located at the insertion end of the connecting ear plate, and the positioning pin is a tapered positioning pin. The positioning hole is located in the circumferential direction at the opening position of the mounting hole and is used to guide the positioning pin to insert and match. Specifically, the positioning component enables rapid and accurate positioning during the installation of the magnetic flip indicator. The cooperation between the tapered positioning pin and the positioning hole has an automatic centering function, guiding the positioning pin to smoothly insert into the positioning hole. This effectively avoids installation difficulties or bolt hole misalignment caused by positional deviation between the mounting hole and the connecting ear plate, significantly improving the assembly efficiency of the magnetic flip indicator.

[0032] In another embodiment of this utility model, such as Figure 6As shown, the detachable connecting component is a snap-fit ​​structure, which includes a snap-fit ​​protrusion and a slot that matches the snap-fit ​​protrusion. The snap-fit ​​protrusion is located on the outer wall of the main measuring float, and the slot is located on the side of the magnetic flip indicator facing the main measuring float. The snap-fit ​​protrusion can be snapped into the slot to form a fixed connection. Specifically, using a snap-fit ​​structure as a detachable connecting component makes the assembly and disassembly of the magnetic flip indicator faster and more efficient. No tools are needed; the snap-fit ​​protrusion and slot can be engaged and disassembled manually, greatly simplifying maintenance operations and significantly shortening the time required to replace the magnetic flip indicator. This is particularly suitable for scenarios requiring frequent maintenance or emergency replacement. The snap-fit ​​structure is simple and intuitive to operate, reducing the skill requirements for maintenance personnel and further reducing maintenance difficulty and safety risks.

[0033] In another embodiment of this utility model, such as Figure 6 As shown, it also includes a sealing gasket, which is disposed between the mating surfaces of the protrusion and the groove, and is used to seal the gap between the measuring main float and the magnetic flip indicator. Specifically, the sealing gasket can effectively seal the gap between the measuring main float and the magnetic flip indicator, preventing impurities such as dust, moisture, and corrosive gases from the external environment from entering the gap, avoiding corrosion and damage to the connecting structure (such as the protrusion and groove) or the outer wall of the measuring main float, and extending the service life of the equipment. In some dusty or humid industrial environments, this sealing function is particularly important, as it can keep the connection parts clean and dry, ensuring the normal operation of the snap-fit ​​structure and the reliability of the connection.

[0034] In another embodiment of this utility model, the detachable connecting component is a slide rail sliding structure, which includes a slide rail and a slider. The slide rail is fixed to the outer wall of the main measuring buoy along its length, and the slider is fixed to the side of the magnetic flip indicator facing the main measuring buoy, with the slider slidingly adapted to the slide rail. Specifically, using a slide rail sliding structure as the detachable connecting component makes the assembly and disassembly of the magnetic flip indicator easier and more convenient. Installation or disassembly can be completed simply by sliding the magnetic flip indicator along the length of the slide rail using the slider. This is particularly suitable for longer magnetic flip indicators, avoiding the tedious steps of disassembling fasteners one by one as in bolted connections, thus significantly improving maintenance efficiency. The cooperation between the slide rail and the slider can precisely guide the movement trajectory of the magnetic flip indicator, ensuring smooth movement during installation and preventing collision damage.

[0035] In another embodiment of this utility model, an elastic buffer is further included, which is disposed between the magnetic flip indicator and the slide rail and the slider. Specifically, the elastic buffer can effectively absorb and mitigate the impact of vibrations and external impacts generated during equipment operation on the magnetic flip indicator, avoid collision damage between the magnetic flip indicator and the slide rail and slider due to rigid contact, protect the precision components (such as magnetic flip columns) inside the magnetic flip indicator, and extend its service life.

[0036] In another embodiment of this utility model, such as Figures 1-2 As shown, the magnetic flip indicator includes a frame and several magnetic flip columns. These magnetic flip columns are rotatably connected to the inside of the frame at intervals along its length, and each magnetic flip column can flip under the magnetic action of the magnetic float to display the liquid level. The frame is connected to the measuring main float via a detachable connection assembly. Specifically, the magnetic flip indicator is designed as a combination structure of a frame and several magnetic flip columns. The frame provides stable installation and protection space for the magnetic flip columns, ensuring their flexibility and accuracy during flipping. The several magnetic flip columns are spaced apart along the length of the frame, making the liquid level indication more precise and continuous, clearly reflecting minute changes in the liquid level and improving the resolution of the liquid level indication. The magnetic flip columns rotate independently, so damage to a single magnetic flip column will not affect the normal operation of other magnetic flip columns, reducing the overall failure probability. Even if a magnetic flip column needs to be replaced, it can be done selectively without replacing the entire magnetic flip indicator, further reducing maintenance costs.

[0037] In another embodiment of this utility model, such as Figures 1-2 As shown, the frame is a split structure, including a left frame and a right frame. The left frame and the right frame are detachably connected by bolts, and the left frame and the right frame, when mated together, form a receiving cavity for accommodating each of the magnetic flip columns. Specifically, designing the frame as a split structure (left frame and right frame) and detachably connected by bolts allows the entire magnetic flip indicator to be removed from the main measuring float when a magnetic flip column is damaged or requires cleaning and maintenance. Only the bolts between the left and right frames need to be removed, and the frame can be opened to inspect, replace, or clean the internal magnetic flip columns, further simplifying maintenance operations.

[0038] In another embodiment of this utility model, a protective shell is further included. The protective shell is disposed on the outside of the magnetic flip indicator, and the protective shell is detachably connected to the magnetic flip indicator. An observation window is provided on the protective shell, penetrating through the side wall of the protective shell, and the position of the observation window corresponds to the indicating area of ​​the magnetic flip indicator. Specifically, the protective shell prevents external objects from colliding with or impacting the magnetic flip indicator, and also blocks harmful substances such as dust, moisture, corrosive liquids or gases from corroding the magnetic flip indicator, significantly extending its service life.

[0039] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
