Description

Technical Field

[0001] This utility model relates to the technical field of float body, and in particular to a novel anti-jamming liquid level float. Background Technology

[0002] A float is a device used in various applications, primarily for water level control, flow measurement, and warning functions. The float consists of a shell, buoyancy adjustment, connection and fixation, sensor control, and safety protection components. It is usually made of lightweight, corrosion-resistant materials such as plastic, stainless steel, or aluminum alloy. The shell is often spherical or cylindrical in shape to ensure good buoyancy performance in liquids, while the design also needs to consider sealing and durability.

[0003] Meanwhile, the float is prone to jamming during movement. This is usually due to insufficient precision in the fit between the float and the guide structure, or the presence of impurities, particles, or other foreign objects in the liquid that enter the gap between the float and the guide rod. In addition, under conditions of frequent liquid level changes or large liquid surface fluctuations, the float may be subjected to irregular impact forces, causing its movement trajectory to deviate, thus increasing the risk of jamming. Poor float stability is mainly manifested in its tendency to tilt, sway, or rotate unexpectedly when moving up and down in the liquid. This instability not only increases the friction between the float and the guide rod, but also causes the liquid level indication to jump or lag, affecting the measurement accuracy. Utility Model Content

[0004] In order to overcome the problem that floats are prone to jamming during movement due to unreasonable structural design or the influence of liquid impurities, and that their poor stability also leads to inaccurate liquid level measurement, this utility model provides a new type of anti-jamming liquid level float.

[0005] The technical solution is as follows: A novel anti-jamming level float includes a level gauge body, auxiliary components, and a sliding component. The auxiliary components for quick installation and maintenance are installed on the outside of the level gauge body. The sliding component inside the level gauge body is used to prevent jamming during the movement of the float by modifying the float structure. The sliding component includes a floating cavity, in which the float body is installed at the center. The inner walls at both ends of the float body are provided with conical grooves to prevent jamming during the movement of the float. The outer middle of the float body is provided with a circumferential flange to ensure buoyancy stability.

[0006] Furthermore, a sliding groove is provided in the center of the float body, and a connecting rod that is slidably connected to the float body is installed vertically in the center of the floating cavity.

[0007] Furthermore, the sliding groove works in conjunction with the connecting rod to achieve sliding guidance, and the connecting rod guides the vertical movement of the float body.

[0008] Furthermore, a support base is fixedly connected to the top of the connecting rod, and a mounting bracket is provided at the center of the upper surface of the support base.

[0009] Furthermore, the auxiliary components include fixing plates, with two sets of fixing plates symmetrically arranged on the outer sides of both ends of the liquid level gauge body.

[0010] Furthermore, fastening frames are installed around both ends of the liquid level gauge body, and the fastening frames are fixedly connected to the fixing plate.

[0011] Furthermore, fixing screws are installed through both sides of the fixed plate surface, and multiple sets of scale grooves are installed on the main surface of the liquid level gauge from top to bottom.

[0012] Furthermore, the scale grooves are arranged radially along the sliding trajectory of the float body.

[0013] The beneficial effects are as follows: This utility model reduces the contact area between the float and the inner wall of the floating cavity through the conical groove design, forming a self-guiding structure that effectively avoids jamming caused by impurities or particles in the liquid. This ensures that the float can move smoothly up and down with changes in liquid level, thereby providing accurate liquid level information. The burr design not only increases the buoyancy area and ensures buoyancy stability, but also helps the float maintain a vertical trajectory, reducing measurement errors caused by tilting or shaking. The cooperative design of the sliding groove and connecting rod guides the float to move only vertically, avoiding jamming caused by lateral deviation. The design of the fixing plate, fastening frame, and fixing screws simplifies the installation process, making the device easy to install and disassemble, and convenient for inspection and maintenance, thereby reducing downtime and improving the overall operating efficiency of the equipment.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Among the currently discovered feasible technologies, the following are described:

[0022] A float is a key component widely used in industrial, civil, and automated control systems. Its main functions include water level control, liquid level measurement, flow monitoring, and alerting for abnormal liquid levels. Its core principle is to sense the liquid level by utilizing changes in the buoyancy of the float within the liquid, and to achieve corresponding control and feedback through mechanical linkage or electronic signal output. The float typically consists of several key parts, including a shell, a buoyancy adjustment mechanism, a connecting and fixing structure, a sensor control module, and necessary safety protection devices. The shell, as the external structure of the float, directly contacts the liquid medium and serves to support and protect the internal components. The buoyancy adjustment mechanism can adjust the overall density of the float according to actual application requirements to adapt to liquid environments with different specific gravities. The connecting and fixing structure ensures that the float can be stably mounted on guide rods, connecting rods, or other support systems, guaranteeing the accuracy of its movement trajectory. The sensor control module converts changes in liquid level into electrical signals for remote monitoring or automatic control. The safety protection design improves the reliability of the float under complex operating conditions, such as explosion-proof, corrosion-proof, and anti-clogging features. In terms of material selection, the main body of the float is mostly made of lightweight and corrosion-resistant materials, such as polymer plastics (e.g., polypropylene, ABS), stainless steel (e.g., 304, 316 stainless steel), or aluminum alloy. These materials not only have good chemical corrosion resistance and anti-aging properties, but also maintain stable physical properties in high temperature, high pressure, or humid environments, thereby extending their service life. From a structural design perspective, the float shell is usually spherical or cylindrical. This geometry not only helps to evenly distribute buoyancy and improve its stability in the liquid, but also reduces water flow resistance and avoids malfunctions caused by liquid disturbance. In addition, the surface of the float often has reinforcing ribs or flow channels to enhance structural strength and improve dynamic response characteristics. Sealing is a crucial aspect of float design, especially in scenarios where it is immersed in liquid for a long time. It is essential to ensure that the internal cavity is completely sealed to prevent liquid infiltration that could lead to buoyancy failure or damage to electronic components. Therefore, floats are typically manufactured using a one-piece molding process or precision sealing structures, such as O-ring seals or threaded compression seals, to ensure their normal operation in various harsh environments. In summary, as a basic but crucial liquid level sensing device, the float plays an important role in multiple fields such as water treatment, petrochemicals, shipbuilding, and home appliances due to its reasonable structure, excellent materials, diverse functions, and stable performance. It is one of the indispensable core components for achieving automatic liquid level control and safety monitoring.

[0023] In liquid level measurement and control systems, the float, as a key sensing component, directly affects the stability and measurement accuracy of the entire system. However, in actual operation, the float often encounters a series of structural and operational problems, the most common being motion jamming and insufficient stability. When moving up and down, the float typically needs to slide along a guide rod or guide tube to ensure the verticality and accuracy of its trajectory. However, in practical applications, due to unreasonable design of the fit clearance between the float's internal guide hole and the guide rod, or insufficient machining precision, it is easy for them to become too tight or have uneven contact. Furthermore, liquid media often contain a certain amount of impurities, particles, or suspended matter. These foreign objects may enter the gap between the float and the guide structure during the float's movement, forming local blockages or frictional resistance, further increasing the risk of float jamming. Especially under conditions of frequent liquid level changes and violent liquid surface fluctuations, the float will be subjected to irregular impact forces from the liquid flow. This impact force will not only cause the float to produce unexpected lateral swaying or rotation, but also cause its trajectory to deviate from the originally set vertical direction. Once the float deviates, the friction between it and the guide structure increases significantly, further exacerbating the jamming phenomenon. In severe cases, it can even cause the float to become completely stuck, failing to reflect the true liquid level changes. Meanwhile, poor float stability is also a significant factor affecting system performance. Ideally, a float should maintain stable vertical movement in the liquid. However, in actual use, due to factors such as unreasonable float center of gravity design, uneven buoyancy distribution, asymmetrical shape, or external disturbances, the float may exhibit unstable behaviors such as tilting, swaying, or even rotation during ascent or descent. This unstable motion not only increases wear between the float and the guide structure, shortening the equipment's lifespan, but also causes jumps or lags in the liquid level indication signal, severely affecting the accuracy of measurement and the response speed of the control system. Especially in complex operating conditions involving high viscosity, high temperature, high pressure, or corrosive media, the stability and anti-jamming capability of the float are particularly important. If the float cannot adapt to these environments due to structural design defects or inappropriate material selection, it is highly susceptible to malfunctions, failures, or even damage, thus affecting the normal operation of the entire liquid level control system.

[0024] like Figures 1-5As shown, a novel anti-jamming level float includes a level gauge body 1, auxiliary components, and a sliding component. The auxiliary components for quick installation and maintenance are installed on the outside of the level gauge body 1. The sliding component is installed inside the level gauge body 1 to prevent jamming during float movement by modifying the float structure. The sliding component includes a floating cavity 301, and a float body 305 is installed in the center of the floating cavity 301. The inner walls at both ends of the float body 305 are obliquely provided with conical grooves 307 to prevent jamming during float movement. A burr 308 is provided in a ring around the middle of the outer side of the float body 305.

[0025] The float body 305 has a sliding groove 306 at its center. The floating cavity 301 has a connecting rod 304 vertically mounted at its center, which is slidably connected to the float body 305. Through the cooperation structure of the sliding groove 306 and the connecting rod 304, the float is stably guided and prevented from deviating. The sliding groove 306 and the connecting rod 304 cooperate to achieve sliding guidance. The connecting rod 304 guides the vertical movement of the float body 305, accurately controls the up and down movement trajectory of the float, and ensures the accuracy and stability of the liquid level measurement. The top of the connecting rod 304 is fixedly connected to a support base 303. The upper surface of the support base 303 has a mounting bracket 302 at its center, which provides a stable support platform for easy installation of sensors or other detection components, thereby enhancing functionality.

[0026] The float body 305 has a flange 308 on its outer center to ensure stable buoyancy in the liquid, making its movement smoother and preventing tilting or swaying. The conical grooves 307 on the inner walls at both ends of the float effectively reduce the contact area with the floating cavity 301, forming a self-guiding structure that automatically avoids obstruction caused by impurities or foreign objects during movement, thus preventing jamming. A sliding groove 306 is located in the center of the float body 305, cooperating with a connecting rod 304 vertically mounted in the center of the floating cavity 301. This sliding connection ensures that the float can only move vertically along the direction of the connecting rod 304, ensuring the straightness and stability of its trajectory and further improving the accuracy of liquid level measurement. A support base 303 is fixedly connected to the top of the connecting rod 304. A mounting bracket 302 is provided on the upper surface of the support base 303, which can be used to install sensors, reed switches, or other detection elements to achieve the acquisition and output of liquid level signals.

[0027] Please see Figures 3-4The auxiliary components include a fixing plate 201. Two sets of fixing plates 201 are symmetrically arranged on the outer sides of both ends of the liquid level gauge body 1. The symmetrical fixing plate 201 design enhances the overall structural strength and provides a reliable support point for installation. The outer sides of both ends of the liquid level gauge body 1 are surrounded by a fastening frame 202. The fastening frame 202 is fixedly connected to the fixing plate 201. The fastening frame 202 enhances the overall sealing and structural stability of the device and facilitates quick assembly and disassembly. Fixing screws 203 are provided through both sides of the surface of the fixing plate 201. Multiple sets of scale grooves 204 are installed sequentially from top to bottom on the surface of the liquid level gauge body 1. The fixing screws 203 enable quick installation and disassembly. The multiple sets of scale grooves 204 provide a clear and continuous liquid level display. The scale grooves 204 are arranged radially along the sliding trajectory of the float body 305. The radial scale layout intuitively reflects the liquid level change and is convenient for manual observation or automated detection and identification.

[0028] The fixing plates 201 are symmetrically installed on the outer sides of both ends of the level gauge body 1, enhancing the overall structural strength and providing stable and reliable support for the installation of the entire device. The fastening brackets 202 are installed around the outer side of the level gauge body 1 and are firmly connected to the fixing plates 201, further improving the structural stability and sealing performance of the device. This ensures the equipment maintains good operating condition even under complex working conditions and supports quick assembly and disassembly, facilitating daily maintenance and replacement. The fixing plates 201 have through-hole fixing screws 203, which allow for quick installation of the entire level gauge onto containers or equipment, improving installation efficiency and ensuring a secure connection. Multiple sets of graduated grooves 204 are arranged radially along the sliding trajectory of the float, providing a clear view of liquid level changes. This facilitates not only manual observation but also integration with automated detection systems such as photoelectric sensors and cameras for identification and monitoring.
