Description

Buoyancy level difference detector {Difference of water level sensing appratus}

The present invention relates to a buoyancy level difference detection device, and more particularly, to a buoyancy level difference detection device capable of quickly and accurately measuring the water level difference on both sides of a beam.

In general, the sluice is installed in agricultural waterways, rivers and concrete beams, and is opened and closed according to the amount of water flowing in, thereby preventing flooding of farmland or preventing backflow of seawater in an area adjacent to the seawater.

In particular, the water gate installed in the area adjacent to the seawater divides the seawater and the inland water. When the amount of the inland water increases due to factors such as rainfall, the water gate is opened to lower the water level of the seawater by preventing the flooding of farmland. When the water level is high, the water gate is closed to prevent the backflow of seawater as described above.

In this way, it is important to know the timing of the opening and closing of the sluice in the area adjacent to the sea, because the water level changes periodically due to the tidal tide.

At low tide, even if the water gate is open due to low seawater level, the seawater does not flow into the inland side, but when the tide is high, the seawater level rises, so that the inflow of seawater occurs to the inland side. Therefore, it was necessary for the manager who manages the opening and closing of the gate to pay attention to the management of the opening and closing of the gate.

A sensing member is provided.

The first and second water level sensing members are buoyant members capable of being floated on the surface of the water, and are connected to both ends of the supporting member by ropes having a predetermined length, respectively, and the supporting members are connected to the first and second levels. It is formed to be rotatable so that both ends connected to the water level sensing member can move in the vertical direction, the suspension means is installed on the beam so as to be located above the rotation support and the rotation support for supporting the support member to be rotatable And a support bracket on which a guide roller is mounted, one end of which is connected to an upper portion of the rotation support part and extended upward, guided to the guide roller, and the other end of which is extended downward, and coupled to the other end of the suspension rope. It is relatively heavier than a support member and the pivot support part, and the support member, the pivot support part, and the first and second water level sensing members are combined. Rather it is preferable to having a lighter weight.

In addition, the support pipe which is supported on the beam extending in the vertical direction and connected to the lower end of the support tube so as to accurately detect the difference in water level between the inner water and the outer water around the beam, and at a height spaced apart from the water by a predetermined distance A first extension tube extending in a direction away from the beam, a second extension tube extending downward from an end of the first extension tube and extending into the water of internal or external water; and a coupling portion of the support tube and the first extension tube and the first extension tube It is preferable to further include a protective container which is installed at the coupling portion of the first and second extension pipes and includes a guide roller for guiding the extension direction of the rope connecting the both ends of the support member and the first and second water level sensing members, respectively. Do.

The buoyancy level difference detection device according to the present invention can quickly and accurately detect the height difference between the internal water and the seawater such as the tidal wave or the flood, so that the opening or closing of the water gate according to the water level can be made quickly.

With reference to the accompanying drawings will be described in more detail with respect to the buoyancy level difference detection device according to the present invention and the automatic hydrological control device using the same.

Referring to FIG. 1, the automatic hydrologic manipulation device 10 of the present embodiment is provided in a beam 11 installed to distinguish internal water and seawater, to prevent backflow of seawater, and to discharge the domestic water to the seawater side.

The beam 11 is formed at the boundary between the seawater and the domestic water, and at one side of the beam 11, a sluice gate 12 is formed to selectively communicate the domestic and seawater so that the internal water can be discharged to the seawater side.

The sluice gate 12 is installed to move up and down along the beam 11, the winch 13 is provided as a driving unit for raising or lowering the sluice gate 12 in the upper portion of the beam (11). The winch 13 is rotated by the drive motor 14, and the water gate 12 is connected to the lower end of the wire 15 wound on the winch 13, so that the water gate 12 is wound or unwound as the wire 15 is wound. The opening or closing is made while this raising or lowering.

1 to 4, the one side of the beam 11 is provided with a water gate opening and closing control means 20 for automatically opening and closing the water gate 12, the water gate opening and closing control means 20 is the sea water and the domestic water side A buoyant water level difference detecting device 21 for detecting the water level difference, and a control unit for opening and closing the water gate 12 according to the water level difference between the sea water and the domestic water side.

The buoyancy level difference detecting device 21 is supported by the first and second water level sensing members 22 and 23 which sense the water level by being floated on the surface of sea water and domestic water, and the first and second water level sensing members 22, 23 of the support member 25 supporting the support member 25, the suspension means 30 mounted on the beam 11 to suspend the support member 25, and the first and second water level sensing members 22 and 23. And a sensing member 27 for measuring a height difference, and the controller opens and closes the water gate 12 according to the height difference between the first and second water level sensing members 22 and 23 measured by the sensing member 27. do.

The first and second water level sensing members 22 and 23 are installed to float on the surface of the seawater and the domestic water, respectively, and since the buoyancy members can be supported on the surface of the water, the height changes together with the change of the water level of the seawater and the domestic water. Done.

The support member 25 is pivotally coupled to the pivot support 35 of the suspension means 30, which will be described later, and has a predetermined length extending from the first and second water level sensing members 22 and 23 at both ends. Each rope 24 is connected. Since the support member 25 is rotatably coupled, when the water level difference between the seawater and the domestic water occurs, the support member 25 is rotated by the height difference between the first and second water level sensing members 22 and 23.

The first and second water level sensing members 22 and 23 are enclosed by the protective cylinder 26, and are raised and lowered according to the height of the water surface in the protective cylinder 26.

The protection container 26 guides the first and second water level sensing members 22 and 23 to extend to a point spaced a predetermined distance from the beam 11 so as to more accurately detect the difference between the seawater and the internal water level.

In general, when the domestic water is discharged to the seawater side, the portion adjacent to the beam 11 may be measured somewhat higher than the actual water level by the internal water discharged through the water gate 12, and in the case of the seawater side, the bottom surface may be far from the beam. Since the slope is deeper and deeper, the point adjacent to the beam may come into contact with the bottom surface of the seawater side when the height of the sea level decreases.

Therefore, in order to detect the exact difference in water level between the seawater and the domestic water, it is preferable that the first and second water level sensing members 22 and 23 are mounted on the sea level and the inner water surface, respectively, at a point separated from the beam 11 by a predetermined distance.

Therefore, the protective cylinder 26 guides the first and second water level sensing members 22 and 23 to be floated at a predetermined distance from the beam 11, and the protective cylinder 26 is provided on the side of the beam 11. End portions of the support tube 26a that is supported and extends in the vertical direction, the first extension tube 26b that extends horizontally away from the beam 11 at the lower end of the support tube 26a, and the first extension tube 26b. And a second extension pipe 26c extending into the seawater or the underwater water.

The first extension pipe 26b is preferably located at a point spaced upward from the surface of the sea water or the inner water by a predetermined distance, and the second extension pipe 26c may be positioned at the bottom even when the water level of the sea water or the domestic water reaches the lowest point. It is preferable to extend sufficiently long from the first extension pipe 26b. And the bottom of the second extension pipe (26c) in order to ensure that the first, second water level sensing members (22, 23) are floated to match the water level of the actual seawater and domestic water, the interior of the second extension pipe (26c) Inflow hole 62 that can be smoothly introduced into is formed. And at the connection point of the support pipe 26a and the 1st extension pipe 26b, and the connection point of the 1st extension pipe 26b and the 2nd extension pipe 26c, the roller 61 for guiding the traveling direction of the rope 24 is provided. It is installed.

Thus, since the first and second water level sensing members 22 and 23 are guided by the protective cylinder 26 and floated at a predetermined distance from the beam 11, the water level difference between the seawater and the inner water side can be detected more accurately. In addition, since the first and second water level sensing members 22 and 23 are surrounded by the protective cylinder 26, breakage may occur due to an external impact or the first and second water level sensing members 22 and 23 may be caused by waves. ), The difference in height is prevented from wider than the actual difference in seawater and water level.

Suspension means 30 is for supporting the support member 25, the support bracket 31 is installed on the beam 11, the rotation support portion 35 for supporting the support member 25 to be rotatable, The guide rope 32 installed on the support bracket 31 is guided to the end of the suspension rope 37 and the other end is connected to the pivot support 35 and the other end is downward, and the weight connected to the other end of the suspension rope 37 38 is provided.

The pivot support part 35 has a hinge bracket 36 coupled to the support member 25 at a lower end thereof. The support member 25 is rotatably coupled to the hinge bracket 36 so that one or the other end is lowered in correspondence with the height difference of the first and second water level sensing members 22 and 23 according to the water level difference. Will be rotated.

The rotation support part 35 is connected to the suspension rope 37 guided by two guide rollers 32 installed on the support bracket 31, so that the rotation support part 35 ascends or descends according to the level of seawater and domestic water. Done. Since the first and second water level sensing members 22 and 23 connected to both ends of the support member 25 are positioned in the sea water and the inland water side with respect to the beam 11, respectively, the support member 25 and Rotating support 35 is preferably located in the upper center of the beam (11). In addition, the guide rail 33 extending in the vertical direction is provided on the lower side of the support bracket 31 so that the rotation support part 35 can move vertically without shaking to the sea side or the inner side in the process of lifting or lowering. The guide bar 34 moving up and down along the rail 33 is coupled to the rotation support part 35 to guide the rotation support part 35 to move up and down vertically.

The weight 38 is heavier than the combined weight of the pivot support 35 and the support member 25, and the pivot support 35, the support member 25, and the first and second water level sensing members 22 and 23 are combined. It is formed lighter than weight. Therefore, the pivot support part 35 and the support member 25 are raised upward by the weight 38. However, when the weights of the first and second water level sensing members 22 and 23 are added, the weight of the weight 38 is lighter, and as a result, the first and second water level sensing members 22, 23 is lifted up and down the support member 25 and the rotational support 35 so that the rope 24 to connect it in a state of being supported on the surface to maintain a certain length. Therefore, even if the water level of the seawater and the domestic water is increased or lowered, the pivot support 35 is lifted or lowered by the weight 38 to connect the support member 25 and the first and second water level sensing members 22 and 23. The rope 24 will always have a certain length.

The sensing member 27 includes first and second contact sensors 28 and 29 installed on the pivot support 35, and the first and second contact sensors 28 and 29 are provided at both sides of the pivot support 35. It is installed on the lower side to detect the rotation state of the support member (25). When the water level becomes high due to the high water, the height of the first water level sensing member 22 becomes relatively higher than the height of the second water level sensing member 23. One end connected to the water level sensing member 22 is rotated upward. When one end of the support member 25 is raised to contact the lower end of the rotation support unit 35, the first contact sensor 28 detects this. Likewise, as shown in FIG. 3, when the water level on the inner side is increased, the height of the second water level sensing member 23 is increased, so that the support member 25 is rotated so that the other end thereof is upward. When the other end is in contact with the lower portion of the rotation support portion 35, the second contact sensor 29 detects this.

The control unit includes a controller 40 that opens and closes the water gate 12 by driving the driving motor 14 by receiving signals transmitted from the first and second contact sensors 28 and 29.

The detection signals detected by the first and second contact sensors 28 and 29 are transmitted to the controller 40. When the detection signals are transmitted from the first contact sensor 28, the controller 40 drives the driving motor 14. By releasing the wire 15 wound around the winch 13 to close the water gate 12 so that seawater does not flow into the inner water side. On the contrary, when the detection signal of the second contact sensor 29 is received, the water gate 12 is opened by driving the driving motor 14 so that the wire 15 is wound around the winch 13 so as to discharge the domestic water to the seawater side. do.

When the water level difference between the seawater and the domestic water occurs as described above, the height difference occurs in the first and second water level sensing members 22 and 23 supported on the respective water surfaces, and the support member 25 is rotated accordingly. Thus, since the water gate 12 is automatically opened and closed according to the water level, the water gate 12 is appropriately opened and closed to block the inflow of sea water according to the increase of the flow rate of the domestic water such as flooding or the change of the height of the sea level due to the difference between tidal waters. It is possible to ensure that a low level of domestic demand is maintained.

The automatic hydrologic manipulation device according to the present invention can be used in the actual industry to open and close the hydrologic gate of the beam provided at the boundary between seawater and domestic water.
