Description

Technical Field

[0001] This utility model relates to the field of liquid level measurement technology, specifically a blocking structure for a magnetostrictive liquid level gauge. Background Technology

[0002] Magnetostrictive level gauges, also known as magnetostrictive level displacement sensors, detect torsional wave pulses generated by the position of a float. These pulses travel back along a waveguide wire at a fixed speed and are detected by a detection mechanism. By measuring the time difference between the pulse current and the torsional wave, the position of the float, i.e., the position of the liquid surface, can be accurately determined. They are widely used in petroleum and chemical raw material storage, industrial processes, dam water level, reservoir water level monitoring, and sewage treatment.

[0003] Currently, when the liquid level changes significantly or experiences abnormal fluctuations, the magnetic float moves rapidly along the measuring rod, exerting a large impact force on the level gauge's blocking structure. Most current blocking structures are rigid and lack effective cushioning measures. Prolonged exposure to the impact of the magnetic float can easily damage the blocking structure, affecting the normal operation of the level gauge, reducing its lifespan, and decreasing measurement accuracy. Therefore, we propose a new blocking structure for magnetostrictive level gauges to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a blocking structure for a magnetostrictive level gauge to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blocking structure for a magnetostrictive level gauge, comprising a level gauge body, a measuring tube fixedly connected to the bottom surface of the level gauge body, a magnetic float slidably connected to the outer surface of the measuring tube, an elastic pad fixedly connected to the outer surface of the magnetic float, two blocks provided on the outer surface of the measuring tube, multiple extension plates fixedly connected to the outer surface of each block, two connecting plates fixedly connected to the outer surface of each extension plate, a connecting rod fixedly connected to the outer surface of every two connecting plates, a collision plate rotatably connected to the outer surface of each connecting rod, an elastic element fixedly connected to the outer surface of each collision plate, and the outer surface of each elastic element fixedly connected to the outer surface of each extension plate.

[0006] In a further embodiment, the outer surface of the measuring tube is provided with two external threads, and the interior of each stop is provided with an internal thread.

[0007] In a further embodiment, each of the external threads engages with each of the internal threads.

[0008] In a further embodiment, a first fixing bolt is threaded onto the outer surface of the measuring tube, and a second fixing bolt is threaded onto the outer surface of the measuring tube.

[0009] In a further embodiment, a base is threadedly connected to the outer surface of the measuring tube, and an isolation net is fixedly connected to the upper surface of the base.

[0010] In a further embodiment, the outer surface of the isolation net is fixedly connected with a plurality of reinforcing rings, and the outer surface of each elastic element is provided with an anti-corrosion layer.

[0011] In a further embodiment, an elastic block is fixedly connected to the outer surface of each collision plate, and the outer surface of each elastic block is provided with anti-slip texture.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The elastic pad on the outer surface of the magnetic float comes into contact with the elastic block on the outer surface of the collision plate, and elastic deformation occurs, which can alleviate part of the impact force. As the collision plate rotates around the connecting rod, the elastic element is compressed during the rotation. The elastic deformation of the elastic element absorbs the kinetic energy of the magnetic float and converts it into elastic potential energy, achieving a double buffering effect. This effectively reduces the damage of the magnetic float impact to the blocking structure and extends the service life of the level gauge.

[0014] 2. The use of internal and external threads makes the installation and disassembly of the entire blocking structure more convenient, facilitating the maintenance and repair of the level gauge and reducing maintenance costs. Attached Figure Description

[0021] 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.

[0022] Example: Figures 1-5 As shown, this utility model provides a technical solution for the blocking structure of a magnetostrictive level gauge, including a level gauge body 1, a measuring tube 2 fixedly connected to the bottom surface of the level gauge body 1, a magnetic float 3 slidably connected to the outer surface of the measuring tube 2, an elastic pad 4 fixedly connected to the outer surface of the magnetic float 3, two blocks 5 provided on the outer surface of the measuring tube 2, multiple extension plates 6 fixedly connected to the outer surface of each block 5, two connecting plates 7 fixedly connected to the outer surface of each extension plate 6, a connecting rod 8 fixedly connected to the outer surface of every two connecting plates 7, and a collision plate 9 rotatably connected to the outer surface of each connecting rod 8. Each collision plate 9 has a fixed outer surface... Each elastic element 10 is connected to an extension plate 6. The outer surface of each elastic element 10 is fixedly connected to the outer surface of each extension plate 6. Each collision plate 9 has an elastic block 18 fixedly connected to its outer surface. The outer surface of each elastic block 18 is provided with anti-slip texture. The elastic block 18 and the elastic pad 4 are made of elastic materials such as silicone or rubber. The elastic element 10 is a helical spring. When the magnetic float 3 moves up and down, the contact between the elastic block 18 and the elastic pad 4 can cause the elastic block 18 and the elastic pad 4 to undergo elastic deformation, which can absorb part of the impact force. The rotation of the collision plate 9 can cause the elastic element 10 to undergo elastic deformation, absorbing part of the impact force, thus achieving a double buffering effect.

[0023] By setting up an elastic pad 4, a stop block 5, an extension plate 6, a connecting plate 7, a connecting rod 8, a collision plate 9, an elastic element 10, and an elastic block 18, a dual buffering effect is achieved. In the first stage of buffering, when the magnetic float 3 moves up and down, the elastic pad 4 comes into contact with the elastic block 18 and undergoes elastic deformation, absorbing part of the impact force. In the second stage of buffering, the collision plate 9 rotates around the connecting rod 8 when impacted, causing the elastic element 10 (coil spring) to undergo elastic deformation, further absorbing the impact force. The dual buffering structure effectively reduces the collision intensity between the magnetic float 3 and the stop block 5 through a two-stage energy absorption mechanism, extending the service life of the level gauge.

[0024] like Figure 2 and Figure 5 As shown, the outer surface of the measuring tube 2 is provided with two external threads 11, and the interior of each stop block 5 is provided with an internal thread 12. Each external thread 11 meshes with each internal thread 12. The outer surface of the measuring tube 2 is threaded with a first fixing bolt 13 and a second fixing bolt 14. By setting the external threads 11 and internal threads 12, the installation and disassembly of the entire blocking structure are more convenient, which facilitates the maintenance and repair of the level gauge and reduces maintenance costs.

[0025] By setting external thread 11, internal thread 12, first fixing bolt 13 and second fixing bolt 14, convenient disassembly and maintenance optimization are achieved. The meshing of external thread 11 and internal thread 12 realizes the pre-positioning of stop 5, simplifying the installation process. The first fixing bolt 13 and the second fixing bolt 14 tighten the stop 5 from both sides of the axial direction to prevent loosening.

[0026] like Figure 2 and Figure 5 As shown, a base 15 is threadedly connected to the outer surface of the measuring tube 2. An isolation net 16 is fixedly connected to the upper surface of the base 15. Multiple reinforcing rings 17 are fixedly connected to the outer surface of the isolation net 16. Each elastic element 10 has an anti-corrosion layer on its outer surface. The anti-corrosion layer can effectively isolate external corrosive substances (such as moisture, oxygen, acid, alkali, etc.) from contacting the metal surface of the elastic element, preventing metal oxidation, rusting or corrosion, and extending the service life of the elastic element. By setting the base 15, isolation net 16 and reinforcing rings 17, large external debris can be prevented from affecting the rise and fall of the magnetic float 3.

[0027] By incorporating a base 15, an isolation net 16, reinforcing rings 17, and an anti-corrosion layer, interference from foreign objects and protection of components are achieved. The isolation net 16 (mesh diameter < 5mm) blocks foreign objects with a diameter ≥ 5mm, reducing the failure rate of the magnetic float 3 by 65%. The reinforcing rings 17 (spacing ≤ 100mm) increase the compressive strength of the isolation net to 80N / cm². 2 To prevent deformation by external forces, the combined effect of mechanical and material protection extends the maintenance cycle of the level gauge and significantly improves its operational reliability in industrial environments.

[0028] The working principle of this utility model is as follows:

[0029] When using this device, the magnetic float 3 moves up and down within the measuring tube 2 as the water level changes. This movement is the key process for measuring the liquid level. However, the magnetic float may experience impact forces due to changes in water flow or other factors during its movement. Therefore, when the magnetic float 3 rises or falls with the water level, it drives the elastic pad 4 connected to it. After the elastic pad 4 comes into contact with the elastic block 18, it can absorb a certain amount of impact energy in the initial stage, mitigating the impact force generated during the movement of the magnetic float and preventing it from being directly transmitted to other structures, thus protecting the stability and accuracy of the device. Then, as the magnetic float 3 moves further, the impact force is transmitted to the collision plate 9 through the elastic pad 4. The collision plate 9 is connected to the connecting rod 8 by a hinge and can rotate freely around the connecting rod 8. When the collision plate 9 is impacted by the magnetic float 3, it rotates and causes the elastic element 10 to be compressed. The design of the elastic element 10 utilizes its excellent elastic properties. When compressed, the elastic element 10 can absorb the kinetic energy of the magnetic float 3 and convert it into elastic potential energy. In this way, the elastic element 10 effectively buffers the impact force, making the movement of the magnetic float more stable and avoiding system damage or measurement errors caused by violent collisions.

[0030] The base 15 is connected to the measuring tube 2 by threads, which ensures the firm fixation of the entire device and improves the convenience of installation and disassembly. The isolation net 16 and the reinforcing ring 17 further enhance the stability of the device. They can effectively prevent large debris or impurities from approaching the measuring tube 2, avoid these debris from interfering with the normal operation of the measuring tube 2, ensure the stable operation of the device in various environments, and reduce the impact of external factors on measurement accuracy.

[0031] The use of external thread 11 and internal thread 12 simplifies the installation and disassembly of the blocking structure, allowing users to quickly and easily maintain and repair the level gauge. This not only improves the ease of operation of the device but also reduces maintenance costs and time, extending the service life of the equipment.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
