Description

Self-draining swing double tank unit {SELF-DRAIN SWING TWIN-BARREL UNIT}

The present invention relates to a self-draining swing twin tank unit, and more particularly, to a self-draining swing twin tank unit configured to efficiently control the double tank to perform liquid flow observation with a load cell.

In general, the types of instruments used for quality observation are tilting, or tipping, weighing, and floating types.

A tipping-bucket-rain recorder is an observation machine that continuously records rainfall. It is a weather observation instrument using a conduction rain gauge and a magnetic contact counter. It is relatively simple to use, it is widely used in automatic weather observation system because it can be measured remotely and the digitization of observation signal is easy, but it is difficult to test or calibrate due to the characteristics of the device.

In conduction magnetometers, the tipping-bucket takes a short time to conduct, so the added rain at that moment is lost in the already calculated rainfall, and due to the discontinuous nature of the record, the light drizzle There is a disadvantage in that it does not provide accurate data. In addition, the conductive rain gauge has the advantage that it is possible to observe the continuous rain, but in the case of strong precipitation it is inaccurate due to the rain water splash phenomenon, the weak precipitation has a disadvantage that it is not detected for a certain period of time.

On the other hand, the weighing rain gauge has the advantage of being able to measure the precision rainwater, but by using the electric motor to rotate the reservoir around a given axis of rotation to upside down to drain, or emptying the rainwater by hand such as hand There is a disadvantage.

In recent years, a weight rain gauge having a double tank capable of draining through a second reservoir while a precipitation is stored in the first reservoir has been studied.

However, the weight rain gauge equipped with such a double tank requires a high degree of precision in the manufacturing process and cannot control the rotation of the reservoir, and there is a problem in that it must depend on arbitrary operation.

In addition, such a heavy weight system has a problem that the drainage is extremely difficult to use a single load cell, and even if the reservoir is installed in the lower part of the load cell by changing the design of the rain gauge, it is difficult to collect water. In other words, it is theoretically ineffective to eliminate the problems related to the storage and drainage of a heavy rain gauge using a single load cell by only changing the rain gauge design.

1A to 1D, a self-draining double tank unit according to an embodiment of the present invention includes a frame member 110, a double tank 120, and a swing controller 130.

The frame member 110 has a rectangular box frame shape and accommodates the twin tank 120 and the swing control unit 130.

The twin tank 120 includes a first reservoir 122 and a second reservoir 124 and is coupled to the inside of the frame member 110 through the rotation shaft 126 to swing around the rotation shaft 126. The first reservoir 122 has a wide cross-sectional area of the opening compared to the bottom, and the second reservoir 124 has a wide cross-sectional area of the opening compared to the bottom.

The cage is shifted to one side than the uppermost portion of the reservoir. Accordingly, the balance of the twin tank 120 is not destroyed while rainfall is stored in the reservoir. However, if rainfall continues to flow after the rainfall is filled in the reservoir, rainfall is filled in the cage so that the balance of the twin tank 120 is broken and rotates about the rotation axis 126.

The swing controller 130 is disposed in the frame member 110 and controls the swing motion of the twin tank 120.

On the other hand, when the swing control unit 130 is disposed below the rotating shaft 126, the protrusion 128 disposed in the twin tank 120 is disposed above the rotating shaft 126.

As the liquid flows into the first reservoir 122 through the opening of the first reservoir 122 and reaches a predetermined volume, the opening of the first reservoir 122 swings downward by its own weight and the second reservoir The opening of 124 swings upward.

The first reservoir 122 rotates in the first direction with respect to the rotation shaft 126 to drain the liquid flow stored therein, and rotates in the second direction to store the liquid flow. The second reservoir 124 rotates in the second direction with respect to the rotation shaft 126 to drain the stored liquid flow, and rotates in the first direction to store the liquid flow. The rotation angles of the first reservoir 122 and the second reservoir 124 are 180 degrees with respect to the rotation axis 126.

Then, the self-draining operation of the self-draining swing double tank 120 unit according to the present embodiment will be briefly described.

When the liquid stored in the first reservoir 122 through the opening of the first reservoir 122 reaches a predetermined volume, the first reservoir 122 is swinged and stored based on the rotation shaft 126 by its own weight. The liquid flows through the opening of the first reservoir 122, and the opening of the second reservoir 124 moves upward to store the liquid in the second reservoir 124. At this time, the protrusion 128 is fitted into the gap formed in the swing control unit 130 to block the shake recoil of the double tank (120).

In addition, when the liquid stored in the second reservoir 124 through the opening of the second reservoir 124 reaches a predetermined volume, the second reservoir 124 is swinged about the rotary shaft 126 by its own weight. The stored liquid flows through the opening of the second reservoir 124, and the opening of the first reservoir 122 is moved upward to store the liquid in the first reservoir 122. At this time, the protrusion 128 is fitted into the gap formed in the swing control unit 130 to block the shake recoil of the double tank (120).

As described above, after designing the reservoir considering the center of gravity, the same reservoir is combined in an upright and upside down position to complete the twin tank, and when the reservoir reaches a certain level, the self drainage In order to stabilize the attitude of the reservoir and swing the counterclockwise only under the given conditions, the swing control unit is added as a rotation stop device to efficiently control the double tank, and the amount of liquid flow can be observed using the load cell.

And a portion of the second rectangular frame 112, and cover all of the fourth side members, a part of the first side members, and a part of the third side members.

FIG. 3A is a perspective view for schematically illustrating the first reservoir 122 or the second reservoir 124 constituting the twin reservoir 120 shown in FIG. 1A, and FIG. 3B is the first reservoir 122 of FIG. 3A. Or a plan view for explaining the second reservoir 124, FIG. 3C is a left side view for explaining the first reservoir 122 or the second reservoir 124 of FIG. 3A, and FIG. 3D is the first reservoir of FIG. 3A. It is a front view for demonstrating 122 or the 2nd water tank 124. FIG.

3A to 3D, the first reservoir 122 or the second reservoir 124, which is the unit reservoir constituting the twin tank 120, has a wider cross-sectional area of an opening, which is an upper end than a bottom, which is a lower end of the reservoir. When the water level of the liquids stored in the first reservoir 122 or the second reservoir 124 rises above the position of the rotational axis in the vertical direction, the left and right balance is broken when the water surface fills the wide cross-sectional area of the water tank. Rotate about

The somewhat complicated shape is to control the desired reservoir posture when the twin tank 120 is configured. In the case of funnels or trapezoidal shapes, such as a single reservoir, there is no guarantee that the unstable reservoir's posture will be rotated 180 degrees to become reversed. That is, a complete multiple is unpredictable and cannot be guaranteed.

In order to prevent the above phenomenon and to achieve a complete 180 degrees or a fully inverted posture, in the present embodiment, the twin tank 120 is configured so that the reservoir once rotated is completely reversed. The twin tank 120 initially takes a reversed position by rotating the reservoir immediately in the normal state about 180 degrees. Accordingly, the reservoir coupled to the reversed state is in a posture transfer to the normal state.

It is not necessary to construct the unit reservoir with a straight line as shown in the drawing, and there is only a part where the cross section of the upper portion of the reservoir suddenly widens. The shape of the area described above is almost independent of the function of the reservoir.

The lower part may be columnar. As in the present embodiment, the structure gradually increasing the cross-sectional area is adopted to shorten the drainage time of the liquid or rainwater accumulated in the reservoir. The relative position on the horizontal plane relative to the lower end of the upper end determines the direction of rotation.

The first reservoir 122 or the second reservoir 124 of the present embodiment is an aspect of turning left from an observer's point of view. From the observer's point of view, the right turn may be thought of as the second reservoir 124 which is symmetrical with respect to the vertical plane of the first reservoir 122. From the observer's point of view, the left and right rotation directions are determined depending on where the horizontal position of the upper end of the opening is located relative to the lower end of the bottom. If the center of gravity of the cross section of the upper end of the opening and the lower end of the bottom coincide in the horizontal plane, it becomes impossible to determine the direction of rotation when it becomes unstable.

FIG. 4A is a perspective view schematically illustrating the twin tank 120 in which the first reservoir 122 and the second reservoir 124 of FIG. 3A are coupled, and FIG. 4B is a diagram illustrating the twin tank 120 of FIG. 4A. 4C is a left side view illustrating the twin bath 120 of FIG. 4A, and FIG. 4D is a front view illustrating the twin bath 120 of FIG. 4A.

4A to 4D, the opening of the first reservoir 122 is disposed upward and the opening of the second reservoir 124 is disposed downward and coupled. That is, the first reservoir 122 and the second reservoir 124 are coupled to each other in reverse phase to define the twin reservoir 120. The rotating shaft 126 is fastened to each of the central portions of both sides of the double tank 120. Accordingly, from the viewpoint of the observer, the twin tank 120 may rotate in the direction in which the protrusion of the forward tank is located with respect to the rotation shaft 126.

Although the shapes of the first reservoir 122 and the second reservoir 124 are illustrated in a straight line in the drawing, any shape other than a straight line may be formed within the limits having a similar topological structure. That is, the first reservoir 122 and the second reservoir 124 of various forms can be manufactured while utilizing the characteristics of the twin tank 120.

The first reservoir 122 and the second reservoir 124, which are two reservoirs of the same shape, are combined in a normal and reversed form.

The size of each of the first reservoir 122 and the second reservoir 124 can be freely determined according to the maximum capacity of the liquid to be contained. Therefore, since the topological shape of the first reservoir 122 and the second reservoir 124 is important, the size of each of the first reservoir 122 and the second reservoir 124 is not limited.

In the figure, a circle or long column-shaped mark represents a cylindrical shaft 126. In actual production, the first reservoir 122 and the second reservoir when the rotary hinge is attached to a portion where the outermost surface of the first reservoir 122 and the second reservoir 124 meet the rotation shaft 126 instead of the rotary shaft 126. The interior of each of the reservoirs 124 is simply configured. However, each of the first reservoir 122 and the second reservoir 124 must be made of a strong material to support the weight of the liquid.

FIG. 5 is a schematic diagram for schematically explaining an operating principle of the self-draining swing twin tank unit shown in FIG. 1A. In FIG. 5, a second reservoir 124 (shown in FIG. 4A) is disposed in an area close to the viewer, and a first reservoir 122 (shown in FIG. 4A) is disposed in an area far from the viewer.

Referring to FIG. 5, when the swing controller is removed, liquids may not be contained in the first reservoir 122 or the second reservoir 124 ((a) state). It is a technical feature of the present invention to be further defined around the axis of rotation in consideration of the center of gravity only. The water tank is made lighter than the bottom of the water tank with respect to the axis of rotation by the upper part of the axis of rotation, that is, the two protruding ends. The production of a tank having a weight or a pendulum can be realized by vertical movement of the rotating shaft 126 based on the thickness of the tank wall, the density distribution of materials forming the tank, or (a) state.

Initially, the tank in (b) remains heavier on the right side than the left side until the reservoir reaches the top of the left projection in the vertical direction (ie, the top of the reservoir). When the tank is almost full, the left side is heavier than the right side with respect to the rotation axis of the tank structure and rotates counterclockwise. When the water level of the first reservoir tank 122 of the double tank reaches a certain height, it stays in the (e) state through the (c) state and the (d) state. (c) state and (d) state is a state in which the liquid flows stored in the first reservoir 122 is drained, and (e) state is a state in which the liquid flows stored in the first reservoir 122 are completely drained. If it is a perfect twin tank without defects, the swing time, i.e. the time to reach state (e) from state (e) is less than one second.

In the state (e), the liquid is stored in the second reservoir 124 while the measurement is made and when it becomes unstable, the state reaches the state (b) through the states (d) and (c) in the reverse order and reaches the first reservoir 122. It is maintained until the liquids have collected sufficiently. The above-described process, that is, after storing the liquid flow in the first reservoir tank 122 and draining, the process of storing the liquid flow in the second reservoir tank 124 and then draining.

FIG. 6A is a perspective view schematically illustrating a swing control unit 130 of the self-draining swing twin tank 120 unit illustrated in FIG. 1A, and FIG. 6B is a plan view illustrating the swing control unit 130 of FIG. 6A. FIG. 6C is a left side view illustrating the swing control unit 130 of FIG. 6A, and FIG. 6D is a front view illustrating the swing control unit 130 of FIG. 6A.

6A-6D, the swing control unit 130 includes a housing 132 and a clutcher 134.

The swing control unit 130 is for controlling the swing motion of the twin tank 120, and may be installed on an upper portion of the rotation hinge of the frame member 110 as shown. Alternatively, it may be installed under the rotary hinge. When the swing control unit 130 is installed below the rotation hinge of the frame member 110, it is necessary to adjust the arrangement of the protrusion 128 of the twin tank 120 to allow the swing stop of the reservoir to be performed.

The housing 132 is suitable for a light metal material, and the clincher 134 is suitable for a material having elasticity, such as rubber or silicone rubber, and having good surface adhesion, so as not to be slippery.

The clutch 134 and the housing 132 should be manufactured without being fixed to each other so that the clutch 134 can move freely within the housing 132 without departing from the housing 132. In particular, it should be easy to fold and unfold in the rotation direction of the twin tank (120).

The clutch 134 is operated with the protrusions 128 engaged with each other. When the protrusion 128 approaches the clutch 134 to stop the rotation of the twin tank 120 is to remove the reverse rotation movement due to the repulsive force in the case of a simple rod or cylinder. If the reverse rotation is too large, the function of the twin water tank 120 is meaningless, even if the reverse rotation is weak, the loss of the liquid to collect. The double tank 120 is rotated 180 degrees to stop exactly, it is possible to manufacture excellent rain gauge.

FIG. 7A is a perspective view for schematically illustrating the clutch 134 of the swing controller of FIG. 6A, FIG. 7B is a plan view for explaining the clutch 134 of FIG. 7A, and FIG. 134 is a left side view, and FIG. 7D is a front view for explaining the clutch 134 of FIG. 7A.

7A to 7D, the clutcher 134 includes a lower body 1341, a lower protrusion 1342, a connecting portion 1343, an upper protrusion 1344, and an upper body 1345.

The lower body 1341 has a square pillar shape and is connected to the lower end of the lower protrusion 1342.

The lower protrusion 1342 is connected to the upper end of the lower body 1341 and the lower end of the connecting portion 1343. The lower protrusion 1342 has a fan shape and expands closer to the upper protrusion 1344, and extends beyond the outer portion of the lower body 1342.

The connecting portion 1343 has a width smaller than the width of the lower protrusion 1342 and the width of the upper protrusion 1344 to connect the lower protrusion 1342 and the upper protrusion 1344.

The upper protrusion 1344 is connected to the lower end of the upper body 1345 and the upper end of the connecting portion 1343 and extends beyond the outer side of the upper body 1345. The lower end of the upper protrusion 1344 has a shape surrounding the upper end of the lower protrusion 1342 having a fan shape.

FIG. 8 is a schematic diagram schematically illustrating a state in which the protrusion 128 reduces recoil when the clutch 134 of FIG. 7A rotates left.

Referring to FIG. 8, the shape of the clutcher 134 (clutcher) before the impact is shown in the left figure, and the shape of the clitcher deformed due to the impact is shown in the right figure.

As shown in the figure on the right, when the twin bath 120 is turned left (counterclockwise) from an observer's point of view, the protrusion 128 of the twin bath 120 is inserted into the gap of the clutcher 134 and then oversized. . Subsequently, the protrusion 128 of the twin tank 120 moves in the opposite direction (clockwise) to the original traveling direction (counterclockwise) and then temporarily stops.

On the other hand, when the protrusion 128 of the twin tank 120 is rotated to the right (clockwise), the protrusion 128 naturally leaves the gap of the clutch 134.

The opposite phenomenon occurs when the twin tank 120 of the rain gauge rotates left and when the water level of the reservoir rises to the right, the interaction between the clutcher 134 and the protrusion 128 is different. In other words, the former is a case where the clutch 134 stops the movement of the reservoir, which rotates rapidly. In this case, a large amount of impact accompanying high speed is observed to rotate in the opposite direction of the twin tank 120 due to recoil. However, because of the shape of the clutch 134, this recoil can be greatly reduced or eliminated.

When the liquid reaches the water tank again and reaches a certain level and the twin tank 120 swings in the opposite direction, the twin cylinder 120 slowly moves, so that the twinning tank 120 having the protrusion 128 can continue to turn right. do.

In the present exemplary embodiment, the twin bath 120 performs a circular motion, but the horizontal motion or similar inclined motion may also be controlled to reduce the recoil of the twin bath 120.

FIG. 9 is a schematic diagram schematically illustrating a state in which the self-draining swing twin tank unit 100 shown in FIG. 1A is applied to a rain gauge.

Referring to FIG. 9, the rain gauge according to the present embodiment includes a self-draining swing twin tank unit 100, a funnel 200, a support disc 300, four load cells 400, and two sliding hinges 500. ).

Since the self-draining swing twin tank unit 100 has been described above, a description thereof will be omitted.

The funnel 200 collects the descending precipitation and provides it to the first reservoir or the second reservoir of the self-draining swing twin tank unit 100. If the opening of the first reservoir is arranged upwards, the funnel 200 will provide the collected precipitation to the first reservoir, and if the second reservoir is arranged upwards, the funnel 200 will remove the collected precipitation. 2 will provide the reservoir.

The support disc 300 is disposed below the self-draining swing twin bath unit 100.

Each of the four load cells 400 is disposed on the support disc 300 to correspond to the lower corner area of the self-draining swing twin tank unit 100. Here, a load cell is also called a load converter and is a load-electric converter that outputs an electrical signal proportional to the load. The most commonly used method is to use a resistive torsion gauge. This method is a method of deriving the resistance change of a torsion gauge as an electrical signal using a bridge circuit to an elastic body deformed to a load. The measuring range varies depending on the structure of the elastic body, but may range from several gf to over 100 tf. The method of using a torsion gauge can make the displacement of the elastic body considerably small, so that it can be made compact and lightweight. In addition, since the torsion is directly converted into an electrical signal, it is also able to follow the dynamic change and to easily measure the telemetry.

Each of the two sliding hinges 500 is arranged to surround the first side and the second side of the self-draining swing twin bath unit 100. Each of the hinges is fastened to the first side and the second side of the self-draining swing twin bath unit 100, and each of the posts is inserted into two holes formed in each of the hinges. Here, it should be obvious that the friction force between the hinge and the post should be manufactured.

In the case of this embodiment, the sliding hinge 500 is practically unnecessary. The relationship between the number of sliding hinges 500 and the number of load cells 400 required is as follows.

When two or less load cells 400 are used, the props of the sliding hinge 500 may be one or more in theory, but two or more are preferable.

When three or more load cells 400 are used, the support of the sliding hinge 500 can be used, but the support is practically unnecessary.

In FIG. 9, the mounting portion of the load cell 400 is visible in four corner areas, that is, four points (one is due to the projection time) of the self-draining swing twin bath unit 100 disposed on the support disc 300. Not). However, it can be installed anywhere on the top, bottom or side according to the manufacturer's idea of manufacturing a rain gauge. Of course, the installation in consideration of the characteristics of the load cell 400 is the basic.

When the water level in the reservoir reaches a certain level, self drainage occurs. The swing control device, which is a rotation stop device, is added to stabilize the attitude of the reservoir and swing half a rotation only under a given condition so that the dual tank can be efficiently controlled to perform liquid flow, for example, precipitation observation using a load cell.

In addition, according to an embodiment of the present invention, it is possible to manufacture an IoT based rain gauge that removes the disadvantages of the existing rain gauge and operates independently at the same time. In addition, the magnetic drainage is simpler and more precise than the conventional rain gauge because it does not require the operation or control of the rotary motor.

In addition, according to an embodiment of the present invention, if the precision is increased, it can be used as a precipitation detector, and if the short time observation interval and the observed data in real time can be used as a seismograph.

In addition, according to an embodiment of the present invention, by forming a twin tank including the first and second reservoir tanks, drainage is possible while the liquid flow is stored, eliminating the observation limit value of the existing weight rain gauge and high precision Similar to the conduction type, a weight rain gauge that can be continuously observed can be manufactured. In addition, since the swing control unit is installed on both sides of the twin tank, the amount of loss of the liquid can be minimized even if the liquid is stored at a strong pressure.

Although described above with reference to the embodiments, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below. I can understand.
