Description

Technical Field

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

[0002] Float level switches are widely used in liquid level detection equipment, especially in industries such as water treatment and petrochemicals, to monitor changes in liquid level in real time. Their working principle is based on the movement of a float as the liquid level rises and falls. The movement of the float triggers a switching mechanism to achieve liquid level control. However, with the increasing complexity of application environments, level switches need to have more flexible and reliable adjustment and maintenance functions. Especially when facing different liquid level heights and the lifespan of the level switch, traditional float level switches are prone to being unable to adapt to changes in water level height in certain special applications, leading to measurement errors or ineffective detection.

[0003] Traditional float level switches typically consist of a float, a fixed bracket, a switching mechanism, and connecting parts. The float uses its own buoyancy to synchronize with the changes in the liquid level, driving the internal mechanism of the switch to determine the liquid level height.

[0004] Existing float level switches, due to their fixed design, often fail to achieve effective contact between the float and the liquid when the water level changes, thus affecting measurement accuracy. This is especially true when the water level fluctuates significantly. Traditional float level switches cannot adapt to different water levels, resulting in ineffective level detection. As application requirements continue to increase, existing level switches are showing their shortcomings in terms of applicability and flexibility. Therefore, this paper proposes a new float level switch to address the problem of float level switches failing to accurately measure water levels when they vary. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a float level switch, which aims to improve the problem in the prior art that fixed float level switches are difficult to contact and measure liquids when water levels are different.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a float level switch, comprising a hollow column, a protective cover fixedly connected to the top of the hollow column, a motor fixedly connected inside the protective cover, a threaded column fixedly connected to the output end of the motor, the threaded column being rotatably connected inside the hollow column, and a sliding component being provided inside the hollow column.

[0007] The sliding assembly includes a sliding column, which is slidably connected inside the hollow column. A threaded column is threadedly connected inside the sliding column. A liquid level ball is slidably connected to the outer wall of the sliding column, and a snap-fit ​​assembly is provided inside the liquid level ball.

[0008] As a further description of the above technical solution:

[0009] The buckle assembly includes a fixing plate and a pin. The outer wall of the fixing plate is fixedly connected to the inside of the liquid level ball, and the side wall of the pin is fixedly connected to the outer wall of the fixing plate.

[0010] As a further description of the above technical solution:

[0011] An electromagnetic block is fixedly connected to the outer wall of the hollow column, and a base is fixedly connected to the bottom of the sliding column.

[0012] As a further description of the above technical solution:

[0013] A receiver is provided on the outer wall of the hollow column, and a transmission line is provided between the receiver and the electromagnetic block.

[0014] As a further description of the above technical solution:

[0015] A liquid level ball 2 is slidably connected to the outer wall of the sliding column, and a hollow block is provided inside the liquid level ball 2.

[0016] As a further description of the above technical solution:

[0017] The hollow block is fixedly connected inside the liquid level ball, and a retaining ball is slidably connected inside the hollow block.

[0018] As a further description of the above technical solution:

[0019] A spring is installed inside the hollow block. One end of the spring is fixedly connected to the inside of the hollow block, and the other end of the hollow block is fixedly connected to the outer wall of the ball.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the output end of the protective cover drives the threaded column to rotate inside the hollow column, which in turn drives the sliding column to rotate, and at the same time drives the base below to move synchronously, thereby achieving the effect of adjusting the length of the float level switch. This solves the problem that when the water level is different, the fixed float level switch is difficult to contact the liquid for measurement, and improves the applicability of the float level switch.

[0022] 2. In this utility model, the fixing plate and pin inside the liquid level ball one move to the hollow block inside the liquid level ball two. Then the pin squeezes the ball and compresses the spring. Then the spring releases its elasticity, thereby achieving the effect of assembling and disassembling the liquid level ball one and the liquid level ball two. This solves the problem of difficulty in replacing the float when the surface is rusted, and improves the practicality of the float level switch. Attached Figure Description

[0029] 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.

[0030] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a float level switch, comprising a hollow column 1, a protective cover 2 fixedly connected to the top of the hollow column 1, a motor 10 fixedly connected inside the protective cover 2, and a threaded column 9 fixedly connected to the output end of the motor 10. The threaded column 9 is rotatably connected inside the hollow column 1. The rotation of the threaded column 9 drives the movement of a sliding column 6 to adjust the float level switch. A sliding assembly is provided inside the hollow column 1 to support and guide the smooth movement of the sliding column 6.

[0031] The sliding assembly includes a sliding column 6, which is slidably connected inside the hollow column 1, allowing the sliding column 6 to slide up and down or longitudinally within the hollow column 1. A threaded column 9 is threadedly connected inside the sliding column 6. When the threaded column 9 rotates, it drives the sliding column 6 to slide along the hollow column 1, thereby adjusting the liquid level. A liquid level ball 7 is slidably connected to the outer wall of the sliding column 6. The liquid level ball 7 moves up and down with the movement of the sliding column 6, responding to changes in the liquid level. A latching assembly is provided inside the liquid level ball 7. The function of the latching assembly is to ensure the stable connection between the liquid level ball 7 and the sliding column 6, and to facilitate disassembly and replacement when needed. When the position of the liquid level ball 7 changes with the movement of the sliding column 6, the latching assembly can ensure that the liquid level ball 7 remains stable in the correct position, preventing loosening caused by changes in the liquid level.

[0032] Specifically, when using a float level switch for water level measurement and control, especially when precise control of water levels at different depths is required, the device drives the threaded column 9 to rotate via the output of the motor 10, thereby driving the sliding column 6. The rotation of the threaded column 9 causes the sliding column 6 to slide smoothly inside the hollow column 1. As the sliding column 6 moves, it not only changes the total length of the level switch but also simultaneously drives the lower level ball 7 and the base 8 to move vertically. This synchronous movement adjusts the relative position of the level ball 7 and the base 8, thus adapting to different water depths. Through this adjustment mechanism, the float level switch can flexibly respond to different water level conditions, achieving precise water level control and measurement, ensuring stable operation of the equipment in various environments, and improving the applicability and reliability of the system.

[0033] Reference Figure 3 and Figure 4 The snap-fit ​​assembly includes a fixing plate 12 and a pin 13. The outer wall of the fixing plate 12 is fixedly connected to the inside of the liquid level ball 7, and the side wall of the pin 13 is fixedly connected to the outer wall of the fixing plate 12. The design of the snap-fit ​​assembly ensures that the liquid level ball 7 can be stably connected to the sliding column 6 and effectively adjusted and positioned when the liquid level changes. An electromagnetic block 5 is fixedly connected to the outer wall of the hollow column 1. The electromagnetic block 5 is connected to the transmission line 4 between the receiver 3 and the electromagnetic block 5. The electromagnetic block 5 can generate magnetic force through the action of current, thereby controlling the response of the sliding column 6 and the float liquid level switch. The receiver 3 set on the outer wall of the hollow column 1 is responsible for receiving the signal from the electromagnetic block 5 and transmitting it to the controller. A base 8 is fixedly connected to the bottom of the sliding column 6, and a liquid level ball 11 is slidably connected to the outer wall of the sliding column 6. The movement of the liquid level ball 11 changes with the sliding of the sliding column 6, thereby responding to the rise and fall of the liquid level.

[0034] A hollow block 14 is installed inside the second liquid level ball 11, and is fixedly connected inside the second liquid level ball 11, serving to support and fix the liquid level ball. A retaining ball 16 is slidably connected inside the hollow block 14, and the retaining ball 16 slides up and down according to changes in the liquid level. A spring 15 is installed inside the hollow block 14, and the function of the spring 15 is to provide stable feedback through elastic force. One end of the spring 15 is fixedly connected inside the hollow block 14, and the other end is fixedly connected to the outer wall of the retaining ball 16, ensuring that the retaining ball 16 is subjected to appropriate pressure and preventing the retaining ball 16 from loosening or shifting position.

[0035] Specifically, when the float level switch needs to be disassembled and replaced, firstly, by pulling the level ball 7 and level ball 11, they are separated from the sliding column 6, thus making the float level switch components independent. Next, the surfaces of level ball 7 and level ball 11 need to be cleaned to remove possible dirt and impurities, ensuring the normal operation of the components and extending their service life. Subsequently, inside level ball 7, there is a fixing plate 12 and a pin 13, which apply pressure to the retaining ball 16 inside the hollow block 14. When the retaining ball 16 is squeezed, it will slide smoothly inside the hollow block 14, while compressing the spring 15. After being compressed, the spring 15 releases its elasticity, causing the retaining ball 16 to engage tightly with the pin 13, ensuring the fixation of the float assembly. This design allows the float assembly of the float level switch to be easily installed and disassembled, and users can easily replace or maintain it, improving the convenience of equipment maintenance and the stability of long-term use.

[0036] Working principle: When using a float level switch to measure and control water levels, and when different water levels need to be measured and controlled, the output of motor 10 drives the threaded column 9 to rotate, which in turn drives the sliding column 6 to slide inside the hollow column 1. During the sliding process, the sliding column 6 simultaneously drives the lower level ball 7 and the base 8 to move synchronously, thereby adjusting the length of the float level switch to accommodate different water depths. After long-term use, rust will form on the surface of the float due to its constant contact with various liquids. When disassembly and replacement are required, the level ball 7 and level ball 11 are pulled to separate them from the sliding column 6. Then, the surfaces of level ball 7 and level ball 11 are cleaned. Then, the fixing plate 12 and the pin 13 inside level ball 7 are used to press the locking ball 16 inside the hollow block 14. When the locking ball 16 is pressed, it slides inside the hollow block 14 and compresses the spring 15. Then, the spring 15 releases its elasticity, so that the locking ball 16 engages with the pin 13, thereby achieving the purpose of installing and removing the float of the float level switch.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
