Description

Magnetic level gauge rotator and level gauge including it {Magnetic level gauge rotator and Level gauge having the same}

The present invention relates to a magnetic level gauge rotor that displays the liquid level using magnetic force, and a level gauge including the same. More specifically, the magnetic level is easy to maintain and change the alignment, and is easy to manufacture and maintain. It relates to a gauge rotor and a level gauge comprising the same.

Generally, a liquid container, such as a tank made to receive or store a liquid, is usually provided in a closed condition, and it is difficult to directly observe the inside of the container except when the inlet is open. In particular, when the liquid contained in the container is a special liquid that cannot contact the outside air or an unstable liquid that reacts sensitively to external light, the container may be provided in a completely closed state, or the surface of the container may be completely opaque. It is not very easy to directly measure or grasp the level of liquid contained in the container (height from the bottom of the container to the surface of the liquid).

For this reason, a level gauge should be installed outside the container containing the liquid. The level gauge may include a plurality of rotors including magnets, as disclosed in US Pat. No. 6,435,026 B1, wherein a floater having magnetics floating on the surface of the liquid exchanges magnetic forces with the rotors to allow the inside of the tank or vessel to be filled. The level of liquid contained can be indicated.

The level gauge indicates the height of the surface of the liquid as the rotor is rotated and aligned by the magnetic force or the alignment is switched. The conventional level gauge has a problem in that the rotation of the rotor is not smoothly performed by friction, which is unexpected. Even if the rotation of the rotor is prevented, it is difficult to solve it easily. In this case, the alignment of the rotor is not easily switched, and the level of the liquid may be unclearly displayed. In addition, in the conventional case, the magnet is formed integrally with the rotor, or the entire rotor is formed to have a magnetic problem in which it is difficult to easily replace or repair the same.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with reference to the drawings. It should be understood, however, that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, It is intended to give the owner a complete indication of the category of design, and the design is only defined by the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, a magnetic level gauge rotor and a level gauge including the same according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 8B.

1 is a perspective view of a level gauge according to an embodiment of the present invention, Figure 2 is a partially enlarged perspective view of a magnetic level gauge rotor according to an embodiment of the present invention coupled to the level gauge of FIG.

First, referring to FIG. 1, the level gauge 1 according to an embodiment of the present invention is rotatably coupled to one side of the frame 100 and the frame 100, according to an embodiment of the present invention. Magnetic level gauge rotor (200). The frame 100 may be formed in a box shape extending in a vertical direction, and inside the panel receiving portion 110, which is a space indented in the vertical direction, may also be formed in the inside of the frame 100. have. The magnetic level gauge rotor 200 may be coupled to one side of the frame 100, in particular, the inner side through the panel receiving unit 110. The magnetic level gauge rotor 200 includes a magnet block 220 as shown in FIG. 2.

On the other hand, the other side of the frame 100 is coupled to the liquid container 300 in the form of an empty container or tube. The liquid container 300 may be a tank or a container in which a liquid is stored, or may be connected to a tank or a container having a larger capacity in which a large amount of liquid is stored through the flow path 320. The liquid receiving part 300 may be firmly coupled to the cover part 120 fixed to both ends of the frame 100 through a screwing method. In the liquid container 300, a floater 310 coupled with a magnet core 311 is accommodated together with a liquid.

By coupling the frame 100 and the liquid container 300, the plotter 310 and the magnetic level gauge rotor 200 are kept adjacent to each other as shown. Through this, each of the magnetic core 311 and the magnetic level gauge rotor 200 coupled to the plotter 310 may exchange magnetic forces with each other, and the position of the plotter 310, that is, the floater 310 floats. The alignment of the magnetic level gauge rotor 200 is switched according to the surface position of the liquid. This makes it possible to easily measure the level of the stored liquid without directly observing the inside of the tank or vessel in which the liquid is stored.

Subsequently, referring to FIG. 2, the magnetic level gauge rotor 200 includes a plate-shaped body 210 and a rotation shaft 213 protruding to both ends of the body 210, and is provided inside the body 210. A fixing protrusion (see 212 of FIG. 3) is formed in the through-hole 211, so that the magnet block 220 may be coupled to be movable. At this time, the rotation shaft 213 is inserted into the circular groove portion 111 formed along the inner side of the frame 100, itself is formed in a bar shape having a plate shape or a predetermined thickness as a whole and the groove portion 111 and Otherwise it forms a square cross section rather than a circle.

For this reason, the rotation shaft 213 is not in close contact with the entire groove portion 111 even after being inserted into the groove portion 111, so that the friction is reduced. Therefore, the magnetic level gauge rotor 200 can rotate smoothly as compared to the prior art. In addition, the movable magnetic block 220 is coupled to move in the direction perpendicular to the axis of rotation (213) can naturally move the center of gravity of the entire magnetic level gauge rotor 200, the magnetic level gauge rotor 200 It is possible to more easily maintain and switch the rotational alignment of the).

Hereinafter, the configuration and operation of the magnetic level gauge rotor 200 will be described in more detail with reference to FIGS. 3 to 7.

3 is a plan view of the magnetic level gauge rotor of FIG. 2, FIG. 4 is a side view of the magnetic level gauge rotor of FIG. 3, and FIGS. 5A and 5B illustrate an assembly process of the magnetic level gauge rotor of FIG. 3. Drawing.

Referring to FIG. 3, the magnetic level gauge rotor 200 is formed from a plate-shaped body 210 having a through hole 211, rotation shafts 213 protruding from both ends of the body 210, and a body 210, respectively. The fixing protrusion 212 extends and protrudes into the through hole 211, and the magnet block 220 is inserted into the fixing protrusion 212. When we explain each component,

First, the body 210 is formed in a plate shape having a predetermined thickness as a whole, but is not a simple rectangular shape, and its edges and perimeters may be partially indented or protruded to form a complicated shape. However, the shape of the body 210 is not limited to this shape, it can be modified to any number of other various shapes.

The plate-shaped body 210 has at least two wide sides. For example, as illustrated, each of the front and rear surfaces of the drawing may be the widest surface of the body 210, and both surfaces of the body 210 may be painted in different colors. Therefore, when the alignment of the magnetic level gauge rotor 200 changes, the color of the body 210 is switched so that the user can easily recognize it.

The through hole 211 penetrates both surfaces of the body 210 painted in different colors. The through hole 211 may be formed in a rectangular shape as shown, but is not limited thereto. The through hole 211 may be modified in any number of other shapes. However, the width of the through hole 211 should be larger than the length of the magnet block 220 coupled to the inside of the through hole 211.

 The fixing protrusion 212 is formed inside the through hole 211. The fixing protrusion 212 has one side connected to the body 210 and the other side extending toward the inside of the through hole 211. The fixing protrusion 212 may be formed in a bar shape having a plate shape or a predetermined thickness, such as the rotation shaft 213 protruding from both ends of the body 210.

Rotation shaft 213 protrudes from both ends of the body 210 as described above. The rotating shaft 213 is not a cylindrical shape having a general axial shape, and is formed in a plate shape or a bar shape as shown in FIG. 2. Therefore, even after being inserted into the circular groove portion (see 111 of FIG. 2), the entire surface of the groove portion 111 may not be in close contact with each other, thereby obtaining an advantage of reducing friction. It can rotate smoothly. In addition, the plate- or bar-shaped rotating shaft 213 has a manufacturing advantage that is easy to be molded integrally with the body 210, which is also plate-shaped.

 The rotating shaft 213 extends in a direction perpendicular to the protruding direction of the fixing protrusion 212. That is, the fixing protrusion 212 and the rotating shaft 213 extend in a direction perpendicular to each other, so that the fixing protrusion 212 intersects with an imaginary straight line connecting the two rotating shafts 213, and is inserted into the fixing protrusion 212. The magnetic block 220 is also to be placed in a direction perpendicular to the rotation axis (213). The different magnetic level gauge rotors 200 are arranged in parallel such that the rotating shafts 213 are parallel to each other, and accordingly, the fixing protrusions 212 included in each of the magnetic level gauge rotors 200 are protruded. The direction or the extension direction lies on the same axis in which the rotation axis 213 is vertical (see FIGS. 1 and 2, respectively).

An expansion portion 214 is formed between the rotation shaft 213 and the body 210 so that the width thereof extends from the rotation shaft 213 toward the end of the body 210. The expansion part 214 may be a part of the body 210, and the width of the expansion part 214 is gradually decreased from the body 210 toward the extension direction of the rotation shaft 213 so that the rotation shaft 213 is inserted (111 in FIG. 2). Contact with a minimum area). This may also reduce the rotational friction of the magnetic level gauge rotor 200.

Although the shape of the extension portion 214 is shown as a semi-circular surface or arc-shaped surface, but is not limited to this, for example, a triangular shape or the other shape that is not shaped, the corner portion in the extending direction of the rotation axis 213. It is possible to form by modifying any number.

The body 210, the rotation shaft 213, the fixing protrusion 212, and the extension portion 214 described so far are all integrally formed and can be arranged on the same plane as each other, and each component is integrally formed in this manner. By doing so, the magnetic level gauge rotor 200 and the entire level gauge can be easily manufactured. However, if desired, each component may be made independently of one another and joined, or may be joined in a mechanical manner.

The magnet block 220 is inserted into the fixing protrusion 212. The magnet block 220 may be formed in a cylindrical shape or a cylinder shape, which is empty inside, unlike the fixing protrusion 212 formed in a plate shape or a bar shape.

The magnet block 220 has two cylindrical bottom surfaces (which are both ends of the magnetic block placed in a direction perpendicular to the rotation axis in the drawing), respectively, to form a positive pole (S pole or N pole) of a magnetic pole. Accordingly, the magnetic poles of the magnet block 220 are arranged in a direction perpendicular to the rotation axis 213 of the magnetic level gauge rotor 200, and the magnetic force lines around the magnet block 220 are shown in FIG. It extends from one of the two bottom surfaces of 220) and is distributed in an overlapping ring shape toward the other one. At this time, the magnetic poles in the drawing are arbitrarily set, and the positions of the N pole and the S pole can be interchanged as necessary.

The insertion hole 221 into which the fixing protrusion 212 is inserted is formed through two bottom surfaces of the magnet block 220. At this time, the cross section of the insertion hole 221 is the same circular shape as the cross section of the cylindrical magnet block 220, the fixing protrusion 212 has a rectangular cross section as described above. Therefore, the fixing protrusion 212 inserted into the insertion hole 221 is also not in close contact with the insertion hole 221, but only in contact with the side portion of the fixing protrusion 212. As a result, the friction is reduced, the magnet block 220 can be easily rotated around the fixing protrusion 212. In addition, since the width of the fixing protrusion 212 is formed larger than the diameter of the insertion hole 221 as shown, the magnet block 220 not only rotates, but in a straight line along the longitudinal direction of the fixing protrusion 212. The flow rate of the magnetic block 220 may increase or decrease according to the width of the through hole 211 and the change of the length of the magnetic block 220 itself.

Since the magnet block 220 rotates the fixing protrusion 212 axially, the position of the two bottom surfaces (both ends placed in a direction perpendicular to the rotation axis on the drawing) does not change during rotation. Therefore, magnetic poles are formed on the two bottom surfaces of the magnet block 220, respectively, and the insertion holes 221 penetrating the two bottom surfaces are formed to insert the fixing protrusions 212 therein, thereby inducing the movement of the magnet block 220. The direction of the magnetic poles may be maintained in a direction perpendicular to the rotation axis 213 of the magnetic level gauge rotor 200.

In this way, by coupling the magnetic block 220 to the body 210 of the magnetic level gauge rotor 200 to be flowable, it is possible to obtain an advantage that the manufacturing is simple. That is, as shown in Figures 5a and 5b, the magnet block 220 is simply inserted into the fixing projections 212, without the need to use any other fastening member or other fixing, adhesive member, level The manufacturing process of the gauge can be simplified compared to the conventional. In addition, even if any one of the body 210 of the magnet block 220 or the magnetic level gauge rotor 200 is damaged it can be easily replaced and used.

Assembly and replacement maintenance work of the magnetic level gauge rotor 200 exposes the fixing protrusion 212 to one side of the body 210, as shown in Figure 5a, the magnetic block 220 to the fixing protrusion 212 Or, on the contrary, it can be made simply by removing the magnetic block 220 from the fixing protrusion 212 and reinserting the new magnetic block 220 without any problem.

After the magnetic block 220 is inserted, the assembly and replacement maintenance work may be completed by restoring the fixing protrusion 212 to be placed on the same plane as the body 210 as shown in FIG. 5B. To this end, the body 210 of the magnetic level gauge rotor 200 may be formed of, for example, a metal material having a suitable plasticity, and if necessary, by using a separate material reinforced with elastic force or by applying a deformation to the structure, elastic force may be applied. It may be reinforced.

FIG. 6 is a plan view illustrating a modified example of the magnetic level gauge rotor of FIG. 3, and FIG. 7 is a diagram for describing an operation process of the magnetic level gauge rotor of FIG. 6.

As shown in FIG. 6, the magnetic level gauge rotor 200a may appropriately increase the flow amount of the magnet block 220 by reducing the length of the magnet block 220. The magnetic block 220 illustrated in FIGS. 6 and 7 is for explaining the flow effect more clearly, and the reduction width of the length and the magnitude of the flow amount may be slightly exaggerated. Although only the length of the magnet block 220 is illustrated in the drawings, the overall size and width of the through hole 211 may be adjusted together to increase the flow amount as described above, and the magnetic level gauge may be adjusted through each mutual adjustment. The magnetic block 220 may be sufficiently flowed such that a change in the center of gravity of the rotor 200a occurs naturally.

The effect of the flow of the magnetic block 220 is as shown in FIG. FIG. 7 illustrates a state in which the magnetic level gauge rotor 200a is placed in the horizontal direction and stops alignment or is placed in the horizontal direction in the middle of the change of the alignment state. Such a situation may be caused by the rotation of the magnetic level gauge rotor 200a being hindered by the friction force between the rotation shaft 213 and the groove portion (see 111 in FIG. 2), and applied to the direction preventing the rotation. It may be caused by external force. In addition, when the level gauge is exposed to the outside for a long time, the rotation may be also interrupted due to the accumulation of foreign matter in each component of the magnetic level gauge rotor 200a.

In this case, the magnet block 220 flows naturally in the left or right direction on the drawing, and the center of gravity of the entire magnetic level gauge rotor 200a is changed accordingly. Even if the magnetic level gauge rotor 200a is placed in the horizontal direction, if the body 210 remains in a completely horizontal state and the center of the magnet block 220 is not in the same state as the center of the body 210, again The magnet block 220 is moved and the center of gravity of the magnetic level gauge rotor 200a is moved.

When the magnetic block 220 flows to change the center of gravity of the magnetic level gauge rotor 200a, the entire magnetic level gauge rotor 200a is naturally rotated downward by the gravity as shown in the drawing. Done. At this time, the direction of rotation of the magnetic level gauge rotor 200a may be clockwise or vice versa (see arrow) on the drawing, and thus the magnetic level gauge rotor 200a may be displaced in a vertical direction. It can maintain state. At this time, the change of the alignment state is primarily caused by the change in the center of gravity, and thereafter it may be sequentially shown by the magnetic force between the poles between the magnetic level gauge rotor 200a adjacent to each other.

When the magnet is fixed to the center of the rotor or all the rotor is formed as a magnet as in the prior art, the movement of its own center of gravity is not possible, even though it is due to a simple friction, there was a problem that this state is not smoothly solved. However, the magnetic level gauge rotor 200a according to the present invention can be easily solved by the natural flow of the magnet block 220 even in such a situation.

8A and 8B are operational diagrams of the level gauge of FIG. 1.

Hereinafter, the operation of the level gauge according to an embodiment of the present invention will be described with reference to FIGS. 8A and 8B.

First, referring to FIG. 8A, when the liquid A is introduced into the liquid container 300, the floater 310 floats on the surface of the liquid A, and the magnet core 311 coupled to the plotter 310. ) Is maintained at the same height as the level of the external liquid storage tank or liquid storage container connected to the liquid container 300. At this time, the liquid container 300 and the storage tank of the outside may be connected through the flow path 320 as described above, the liquid (A) flows into the liquid container 300 through the flow path 320. Can be.

The plotter 310 may be formed, for example, in a cylindrical shape, and may be made of a low density material to float on the surface of the liquid A. On the other hand, the magnet core 311 is coupled to one side of the plotter 310, preferably, inside or the center of the plotter 310 can maintain the same height as the surface height of the liquid (A). In this case, the magnet core 311 does not need to be positioned at the center of the plotter 310, and is appropriately positioned on the plotter 310 in consideration of the center of gravity of the whole plotter 310 and the magnetic weight of the magnet core 311. By being combined with, the water level of the liquid A can be effectively reflected.

 When the floater 310 floats along the inflowed liquid A, the position of the magnet core 311 is changed, and the magnetic force of the magnet core 311 and the magnetic force of the magnetic level gauge rotor 200 interact with each other. As shown, the alignment is changed. Accordingly, the user can easily measure the level of the liquid A by grasping the change position of the magnetic level gauge rotor 200.

At this time, the remaining magnetic level gauge rotor 200 which is not adjacent to the magnet core 311 is maintained in the alignment state in the vertical direction through the above-described alignment process. Since the magnetic level gauge rotors 200 aligned in the vertical direction have one of two surfaces painted in different colors facing the front, the user can change the position of the magnetic level gauge rotor 200 and the position where the change does not occur. Can also be easily distinguished. In the drawing, the upper surface of the magnetic level gauge rotor 200 aligned horizontally toward the plotter 310 at the same height as the magnet core 311 is, for example, the surface painted in red faces the front surface thereof. The bottom can be aligned, for example, with the face painted in green facing the front.

8B, when the inflow amount of the liquid A increases in this state, the surface of the liquid A rises and the plotter 310 simultaneously rises, which causes the magnet core 311 to be positioned above. Another magnetic level gauge rotor 200 is adjacent. At this time, the remaining magnetic level gauge rotors 200 which are not adjacent to the magnet core 311 maintain the alignment state in the vertical direction through the above-described alignment process, and the plotter 310 at the same height as the magnet core 311. Based on another magnetic level gauge rotor 200 aligned toward, for example, the upper side is painted in red, the lower side is painted in green, so that the surface of the liquid A can be easily grasped. It can be.

In the above, embodiments of the present invention have been described in detail with reference to the accompanying drawings, but those of ordinary skill in the art to which the present invention pertains may be embodied in other specific forms without changing the technical spirit or essential features thereof. I can understand that you can. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
