Description

Technical Field

[0001] This utility model relates to the field of instrumentation technology, and in particular to a level transmitter that prevents the float ball from falling off. Background Technology

[0002] Level transmitters are crucial devices for accurately measuring liquid levels in numerous fields, including industrial production, water conservancy monitoring, environmental engineering, and daily life. Their reliability and stability are paramount. In various systems involving liquid storage and transportation, accurate liquid level information plays a decisive role in ensuring safe system operation, improving production efficiency, and achieving automated control. However, in practical applications, the problem of float detachment in level transmitters occurs frequently. This not only leads to inaccurate liquid level measurements but can also cause a series of serious consequences, such as production accidents, resource waste, and environmental pollution. Therefore, developing a level transmitter that prevents float detachment is of extremely important practical significance. It aims to fundamentally solve the long-standing problem of float detachment that has plagued the accuracy and stability of liquid level measurements, providing more reliable and accurate technical support for liquid level monitoring in various industries.

[0003] Traditional level transmitters typically consist of a float, a connecting rod, a sensor, and signal processing circuitry. The float is usually made of a material with a density less than that of the liquid being measured, such as lightweight plastic or hollow metal. Based on Archimedes' principle, the float moves up and down with the rise and fall of the liquid level due to its own buoyancy. One end of the connecting rod is connected to the float.

[0004] In actual use, the connection structure between the float and the connecting rod of the existing level transmitter has obvious defects, which makes the float easy to fall off. The position of the limit block of the transmitter is fixed at the factory and cannot be adjusted according to the changes in the actual application scenario. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a level transmitter that prevents the float from falling off, aiming to improve the problem that the connection structure between the float and the connecting rod in existing level transmitters has obvious defects, which makes the float easy to fall off during actual use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a level transmitter for preventing float ball detachment, comprising a connecting pipe, a quick-release assembly on the outer wall of the connecting pipe, a movable assembly on the outer wall of the connecting pipe, the quick-release assembly including a button, the button being disposed on the outer wall of the connecting pipe, a fixed circular block slidably connected to the inner wall of the button, a movable module fixedly connected to the inner wall of the fixed circular block, a movable rod slidably connected to the inner wall of the movable module, a sealing strip II fixedly connected to the outer wall of the movable rod, a fixed buckle slidably connected to the inner wall of the movable module, a spring I fixedly connected to the inner wall of the button, a connecting module fixedly connected to one end of the fixed circular block, an elliptical float fixedly connected to one side of the outer wall of the connecting module, and sealing strips I being disposed on both sides of the outer wall of the elliptical float.

[0007] Furthermore, the moving component includes a limiting block, which is fixedly connected to the outer wall of the connecting pipe. Gaskets are fixedly connected to both ends of the limiting block. A circular buckle is slidably connected to the inner wall of the limiting block. A moving shaft is slidably connected to the inner wall of the circular buckle. A handle is fixedly connected to the outer wall of the moving shaft. A rotating shaft is rotatably connected to the inner wall of the handle. A second spring is fixedly connected to the inner wall of the handle. One end of the second spring is fixedly connected to the limiting block.

[0008] Furthermore, a flange is fixedly connected to the outer wall of the connecting pipe, a dial is threaded to one end of the connecting pipe, and a groove is opened inside the connecting pipe.

[0009] Furthermore, a sealing strip is attached to the outer wall of the connecting pipe, and a gasket is attached to the outer wall of the connecting pipe.

[0010] Furthermore, a circular buckle is slidably connected inside the connecting tube, and a circular buckle is slidably connected to the inner wall of the limiting block.

[0011] Furthermore, the inner wall of the limiting block is provided with a handle, and the inner wall of the handle is provided with a circular buckle.

[0012] Furthermore, a spring is provided on the outer wall of the movable rod, and a movable module is fixedly connected to one end of the spring.

[0013] Furthermore, an elliptical float is slidably connected to the outer wall of the connecting pipe, and a spring is provided on the outer wall of the connecting pipe.

[0014] This utility model has the following beneficial effects:

[0015] In this utility model, when using a level transmitter that prevents the float ball from falling off, firstly, press the button to push the connected moving rod and spring one to move together. The fixing buckle and the moving rod move in a fixed position within the moving module. The moving module plays an important guiding role here. When the moving module is inserted into the connecting module, a key action occurs, that is, spring one rebounds. Spring one achieves the guiding movement through the button, which tightly locks the fixing buckle on the moving rod. The sealing strip two prevents liquid, dust and other impurities from entering the connection part and affecting the performance of the equipment.

[0016] In this invention, when the limiting block needs to be adjusted, the handle is pressed to rotate around the pivot. At the same time, the movement of the handle will compress the second spring. Simultaneously, the rotation of the handle will also drive the moving shaft connected to it to move, and the moving shaft will in turn drive the circular buckle to move. When the handle is released, the second spring will rebound, so that the handle, the moving shaft and the circular buckle return to their initial positions, achieving an automatic reset effect. The pivot is fixed to rotate by the limiting block, and the shim reduces noise and wear caused by collision. Attached Figure Description

One end of the fixing block 13 is fixedly connected to the connecting module 7. The connecting module 7 cooperates with the moving module 9 and is fixedly connected to it under the action of the fixing buckle 11. It is an important part of the liquid level transmitter connection structure. An elliptical float 4 is fixedly connected to one side of the outer wall of the connecting module 7. Sealing strips 6 are provided on both sides of the outer wall of the elliptical float 4.

[0026] Reference Figures 1-5The moving component includes a limiting block 5, which provides rotational support and limits the range of motion of the float in liquid level measurement. The limiting block 5 is fixedly connected to the outer wall of the connecting pipe 3. Gaskets 15 are fixedly connected to both ends of the limiting block 5. The gaskets 15 are set on the upper and lower surfaces of the limiting block 5 to buffer the collision generated when the float touches the limiting block 5, reduce wear and noise, protect the components, and improve measurement stability. A circular buckle 14 is slidably connected to the inner wall of the limiting block 5. A moving shaft 16 is slidably connected to the inner wall of the circular buckle 14. The moving shaft 16 is driven to move when the handle 17 is rotated, thereby driving the circular buckle 14 to move. It is the key component for transmitting the movement of the handle 17. A handle 17 is fixedly connected to the outer wall of the moving shaft 16. The handle 17 serves as an operating component, making it convenient for the operator to apply pressure. A rotating shaft 18 is rotatably connected to the inner wall of the handle 17. The rotating shaft 18 connects the handle 17 and the limiting block 5.

[0027] Working principle: When using a level transmitter with anti-float ball dislodgement, first press button 8 to push the moving rod 10 and spring 12 to move. The movement of the moving rod 10 drives the fixed buckle 11 to move. The fixed buckle 11 and the moving rod 10 move and are fixed within the moving module 9 to achieve guidance. When the moving module 9 is inserted into the connecting module 7, the spring 12 rebounds. The spring 12 guides the movement through button 8, locking the fixed buckle 11 on the moving rod 10. The fixed buckle 11 fixes the moving module 9 and the connecting module 7. The sealing strip 20 seals the gap between button 8 and fixed block 13, and also seals the gap between the moving rod 10 and the moving module 9.

[0028] When the limiting mechanism needs to be adjusted, the handle 17 is pressed, and the handle 17 rotates through the rotating shaft 18. When the handle 17 moves, it squeezes the second spring 19. At the same time, the movement of the handle 17 drives the moving shaft 16 to move, and the moving shaft 16 drives the circular buckle 14 to move. When the handle 17 is released, the second spring 19 rebounds, achieving an automatic reset effect. The rotating shaft 18 is fixed to rotate through the limiting block 5. The gaskets 15 are all set on the upper and lower surfaces of the limiting block 5 to prevent collisions when the float moves up and down and touches the limiting block 5.
