Mechanical Inclination Measuring Device {MECHANICAL INCLINATION ANGLE MEASUREMENT APPARATUS}

The present invention relates to a mechanical tilt measuring device to which mercury is applied.

In general, a tilt sensor or inclinometer is a sensor that measures the angle of an object with respect to gravity, and is a sensor that outputs a measured value through an appropriate electrical interface.

Conventional mercury switches put mercury and two electrodes in a glass container sealed with an inert gas such as nitrogen, and the glass container tilts left and right depending on the size of the load, and at this time, the mercury moves to connect or block the electrodes. Let it.

However, conventional inclinometers or inclination sensors fail due to electrical errors, and due to the structure of the sensor, one sensor can measure only one axis, and in order to measure two or more multiple axes, there is a problem that a number of sensors must be combined and measured. have. In addition, there is a problem that energy consumption is large because power is always required as an electronic component.

In this regard, Korean Utility Model Publication No. 1997-0003733 discloses a mercury switch that detects the overturning or rotation of the mother body due to the movement of mercury.

Some embodiments of the present invention have been created in order to solve the above-described problems, to provide a mechanical inclination measuring device by applying a conductor material (preferably, mercury) and a non-conducting material (preferably, oil) to a mechanical contact switch. There is a purpose.

In addition, the purpose of this is to prevent corrosion by applying oil as a non-conducting material, and to measure the change and sequence of changes in the multiaxial direction (x1, x2, ... xn) by applying a cylindrical structure.

However, the technical problem to be achieved by this embodiment is not limited to the technical problems as described above, and other technical problems may further exist.

However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and similar reference numerals are assigned to similar parts throughout the specification.

Throughout the specification, when a part is said to be "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element interposed therebetween. . In addition, when a part "includes" a certain component, it means that other components may be further included, and one or more other features, not excluding other components, unless specifically stated to the contrary. It is to be understood that it does not preclude the presence or addition of any number, step, action, component, part, or combination thereof.

Hereinafter, a mechanical inclination measuring device will be described in detail by applying a conductive material (preferably mercury) and a non-conducting material (preferably oil) to a mechanical contact switch.

1 is a view for explaining the configuration of a mechanical tilt measuring device according to an embodiment of the present invention.

Referring to FIG. 1, the mechanical inclination measuring apparatus of the present invention has a cylindrical body portion 10 in which a predetermined ratio of a conductor material and a non-conductor material are enclosed, and extends radially at a certain angle with respect to the central axis of the body portion 10. A plurality of electrode units 20 disposed on the circumference of the body unit 10 intersecting a plurality of axes (x1, x2, ... xn) and at least one electrode unit 20 electrically connected through a conductor material It includes a control unit 30 for measuring the gradient change by receiving a detection signal from.

Here, the electrode unit 20 is composed of a first electrode 210 and a second electrode 220, and four or more axes (x1, x2, x3, x1, x2, x3,) extending radially with respect to the central axis of the body unit 10 x4) can be placed at the intersection of both ends.

2 is a longitudinal cross-sectional view illustrating a conductive material and a non-conducting material enclosed in the mechanical tilt measuring apparatus according to an embodiment of the present invention.

Referring to FIG. 2, when the body portion 10 is horizontal, the electrode portion 20 is disposed adjacent to the upper side of the body portion 10 with respect to a cylindrical longitudinal section, and a first contact with the non-conductive material 120 The electrode 210 and the second electrode 220 disposed adjacent to the lower side of the body portion 10 and in contact with the conductor material 110 are included.

In this case, the conductive material 110 may be made of mercury, and the non-conducting material 120 may be made of a fluid containing oil. For example, the conductor material 110 filled in the body portion 10 serves to connect the first electrode 210 and the second electrode 220 when the body portion 10 is inclined. The non-conductive material 120 fills the remaining empty spaces inside the main body 10 and serves to remove corrosion and errors that may occur inside the main body 10. When the conductor material 110 and the non-conductor material 120 are composed of mercury and oil, the specific gravity is different so that they are not mixed, and mercury is always located in the lower region of the body portion 10.

For example, in the electrode unit 20, the first electrode 210 and the second electrode 220 are spaced apart by a first distance d1, and the conductor material 110 is separated from the height of the body unit 10 In the case of having the second height a2, the sensitivity of the electrode part 20 may be low.

As another example, the first electrode 210 and the second electrode 220 are spaced apart by a second gap d2 that is greater than the first gap d1, or the conductor material 110 is less than the second height a2. In the case of having a small first height a1, the sensitivity of the electrode part 20 may be high.

In other words, in order to detect an object having a large inclination change, the sensitivity of the mechanical inclination measuring apparatus of the present invention is increased by increasing the distance between the first and second electrodes 210 and 220 or reducing the amount of the conductor material 110. It can be adjusted to be low. In addition, in order to detect an object in which a slight gradient change occurs, the amount of the conductor material 110 is increased, or the distance between the first and second electrodes 210 and 220 is decreased, so that the sensitivity of the mechanical gradient measuring apparatus of the present invention is increased. Can be adjusted to be high. That is, the inclination angle, which is a reference to be detected, may be determined through the amount of the conductor material 110 or the distance between the first and second electrodes 210 and 220.

3 is a cross-sectional view for explaining a change in a conductor material according to an inclination direction of the mechanical inclination measuring apparatus according to an embodiment of the present invention.

FIG. 4 is a longitudinal cross-sectional view for explaining a change of a conductor material according to an inclination direction of the mechanical inclination measuring apparatus shown in FIG. 3.

Further, a terminal for an electrode (not shown) extending from the electrode part 20 and protruding toward the outside of the main body part 10 may be further included.

When the main body 10 is inclined, the control unit 30 is connected to the electrode terminals, and based on the detection signals sequentially received from each electrode unit 20, the inclined direction and order of the main body 10 Can be measured. In addition, a separate power supply may be provided in the control unit 30.

First, referring to (a) of FIG. 4, when the main body 10 is inclined downward to the left with respect to the horizontal plane, the conductor material 110 connects the electrode part 20, so that the controller 30 detects Can receive signals. Similarly, referring to (b) of FIG. 4, when the main body 10 is inclined downward to the right with respect to the horizontal plane, the conductor material 110 connects the electrode part 20, so that the controller 30 detects Can receive signals.

That is, the mechanical inclination measuring apparatus of the present invention has an advantage that there is no additional power loss unless the inclination change occurs because the detection signal of the electrode unit 20 is generated only when a change in inclination (tilt) occurs. Accordingly, it is possible to minimize the power loss, it is possible to measure and use for a long time.

Illustratively, referring to FIG. 3, the electrode unit 20 includes a pair of first electrode units 20a and 20a', second electrode units 20b and 20b', and a third electrode facing each other on one axis. Units 20c and 20c' and fourth electrode units 20d and 20d' may be included. Specifically, the first to fourth electrode units 20a-20d' have four axes (x1, x2, x3) radially extending at a certain angle (for example, 30°) with respect to the central axis of the main body 10. , x4) may be disposed on the circumference of the body portion 10 intersecting, respectively.

For example, as shown in (a) of FIG. 4, when the main body 10 is inclined downward to the left with respect to the horizontal plane, as shown in (a) of FIG. 3, it intersects with one side of the x1 axis and The first electrode unit 20a' disposed on the circumference of the portion 10 may be connected by the conductor material 110. In this case, the controller 30 may receive a detection signal from the connected first electrode unit 20a'.

Subsequently, as shown in (b) of FIG. 3, when the main body 10 is rotated counterclockwise by about 30° in a state in which it is inclined downward to the left, it intersects with one side of the x2 axis and the circumference of the main body 10 The second electrode unit 20b ′ disposed thereon may be connected by the conductor material 110. In this case, the controller 30 may receive a detection signal from the connected second electrode unit 20b'.

At this time, the control unit 30 sequentially receives detection signals from the first and second electrode units 20a' and 20b', and the inclined direction of the main body 10 is to the left of the x1 axis, first, toward the x1 axis. It can be measured that it is tilted and then rotated about 30° counterclockwise along the x2 axis.

In this way, by arranging the electrode part 20 on the multi-axis (x1, x2, …, xn), it is possible to check the change in inclination in various directions, and by checking the rotation order of the cylindrical body part 10, it is more precisely tilted. You can check the direction and order of losing.

The control unit 30 is based on the detection signal sequentially received from the electrode unit 20 connected as at least one of the first anode 210a to the Nth anode 210n and the conductor material 110 contact The inclination angle can be measured in the inclined direction of (10).

Specifically, the first electrode 210 includes first to N-th anodes 210a, 210b, ... 210n spaced at a predetermined inclined interval, and the second electrode 210 is an N-th anode 210n It may include a cathode spaced apart from. In this case, the inclination interval d3 is a reference for measuring the inclination angle of the main body 10 with respect to the horizontal plane when the main body 10 is inclined, and the inclination angle may preferably be 5°, but is not limited thereto. .

For example, as shown in FIG. 5, the first electrode 210 may include first to fifth anodes 210a to 210e. At this time, the inclination distance d3 between the first anode 210a to the fifth anode 210e may be set to correspond to an inclination angle (for example, 5°) that is a measurement criterion for a change in inclination of the main body 10. have.

As an example, when the second electrode 220 and the fifth anode 210e located at the lowermost side of the first electrode 210 are connected by the conductor material 110, the controller 30 receives a detection signal and It is possible to measure which axis the part 10 is inclined in the direction of the multiple axes (x1, x2, …, xn).

Subsequently, referring to FIG. 6, when the body portion 10 is inclined downward by about 5° to the left, the fourth anode 210d located directly above the fifth anode 210e is connected by the conductor material 110. I can. In this case, the controller 30 may measure what is the inclination angle (eg, 10°) in the inclined direction (eg, x1 axis) of the main body 10.

Likewise, referring to FIGS. 5 and 6, when the main body 10 is gradually inclined downward to the left, the third anode 210c, the second anode 210b, and the third anode 210c are positioned above the fourth anode 210d.
