Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 22.

1 is a plan view of a conventional water storage tank.

Referring to Figure 1, it can be seen that the conventional reservoir has the following problems.

First, if you look at the points where the flow direction of the water changes rapidly in the reservoir, an angle is formed so that the water flowing in the wall forming the angle can hit the front face, and thus it can no longer flow, and can be held. There are problems that can lead to contamination.

Second, there is a problem in that a valve chamber or a water valve must be provided on both sides because the place where the water flows in and the place where the water flows out are far apart.

2(a) and 2(b) are exemplary views of a plan view and a simpler form of a water tank-type water retention preventing reservoir according to a first embodiment of the present invention.

Referring to (a), (b) of FIG. 2, in order to solve the problems of the conventional water storage tank described above with reference to FIG. 1, the water storage type water accumulation prevention water storage tank according to the first embodiment of the present invention is an inflow path 100, It may include an outflow path 800, a wall panel 200, a vortex wall panel 300, and a curved panel 400.

The inflow passage 100 is a passage through which water is introduced into the reservoir, and the water introduced through the inflow passage 100 may flow inside the reservoir.

The outflow passage 800 is a passage through which water flows out of the reservoir.

The inflow passage 100 may be provided adjacent to the outflow passage 800.

When the inflow path 100 is not provided adjacent to the outflow path 800, a valve chamber and a water valve required for the inflow path 100 and the outflow path 800 must be separately installed.

On the other hand, when the inflow path 100 is provided adjacent to the outflow path 800, the inflow path 100 and the outflow path 800 may function as only one valve chamber and a distillation valve.

As a result, the structure of the water tank can be designed more simply, so that it can be easily configured and maintenance is convenient.

At the same time, the present invention provides various embodiments as will be described below so that water in the reservoir can flow smoothly while configuring the inflow path 100 and the outflow path 800 to be adjacent.

The wall panel 200 may be attached to the inner wall of the reservoir, where the inner wall may be a side wall of the reservoir. Other than the ceiling and floor of the water tank, a plate made of a material such as stainless steel may be attached for lining, not the wall panel 200.

The inner wall of the reservoir may be made of concrete, and the wall panel 200 attached thereto may be made of metal, in which case the metal surface may be oxidized and corroded due to flowing water and oxygen present in the flowing water.

Therefore, the metal constituting the wall panel 200 is preferably a metal capable of forming an oxide film, such as stainless steel, and all the panels described below may be the same.

In addition, the wall panel 200 is attached to the inner wall of the water tank to prevent water from leaking out of the water tank.

The flow wall panel 300 is installed inside the reservoir, and the flow path of the water flowing from the inflow passage 100 to the outflow passage 800 may be changed according to the installation form of the flow wall panel 300.

When there is no flow wall panel 300 inside the reservoir, the flow path of the water may not be fixed as one, and may be divided into several paths, so that the water that does not flow may stagnate in the reservoir for a long time and become a shooter.

The flow wall panel 300 may be installed in various forms in the reservoir, but a path leading from the inflow path 100 to the outflow path 800 leads to one path, and the inflow path 100 and the outflow path 800 are adjacent. It is preferably installed so that it can.

The curved panel 400 is between the wall panel 200 and the wall panel 200 in a position in which the flow direction of the water flowing through the inflow path 100 is rapidly changed, and the wall panel 300 and the wall panel 300 ) Can be provided so that the introduced water flows along the curved surface.

If there is no curved panel 400, the vortex wall panel 300 can be connected at an angle to the adjacent vortex wall panel 300, and the wall panel 200 is also adjacent to the adjacent wall panel 200 and the inner wall edge of the reservoir. They can be connected at a constant angle.

When the flowing water hits an edge formed in a space between the wall panel 300 and the wall panel 300 forming a constant angle or a space between the wall panel 200 and the wall panel 200, the water flows and There is a problem in that the flow may be stopped in the opposite direction, and the flow may be stopped or the flow velocity may be significantly slowed down.

The curved panel 400 has an effect of solving this problem so that flowing water can flow smoothly in a set direction along a smooth curved surface.

Referring to (b) of FIG. 2, the shape of the water channel may vary according to the size and internal structure of the water storage tank.

If the size of the water tank is small, the shape of the water channel may be simple, and, conversely, when the size of the water tank is large, the water channel shape may be complex.

In addition, when the skeleton forming the skeleton of the reservoir is installed inside the reservoir, the channel shape can be simply configured accordingly because the flowing water must be configured to minimize interference with the skeleton.

3 is a perspective view of a wall panel of a water tank type water retention prevention reservoir according to a first embodiment of the present invention.

Referring to FIG. 3, the wall panel 200 of the water channel-type water retention prevention reservoir according to the first embodiment of the present invention may include a wall panel connecting portion 210 and a wall panel triangular protrusion 220.

The wall panel connecting portion 210 may be a flat surface that may be formed at both ends or one end of the wall panel, and may be connected to the adjacent wall panel 200 by a predetermined area.

The wall panel triangular protrusion 220 may be provided on one side of the wall panel connecting portion 210, and may protrude into the reservoir to form an angle.

The wall panel triangular projection 220 may be provided in one or more on the wall panel 200, and the angle of the triangular projection may vary according to temperature.

Flowing water in a reservoir can have a different temperature over time or season.

Accordingly, in the absence of the triangular projection 220 of the wall panel, it is impossible to flexibly respond to the temperature change, so the volume of the wall panel 200 decreases, and a gap occurs between the wall panel 200 and the wall panel 200, or As the volume of the wall panel 200 increases, cracks may be generated by the force pushing each other between the wall panel 200 and the wall panel 200.

When the temperature increases and the volume of the wall panel 200 increases, the wall panel triangular projection 220 may receive a force compressed from side to side, and the angle of the triangular projection may be reduced.

When the volume of the wall panel 200 decreases due to a low temperature, the triangular projection 220 of the wall panel may receive an increasing force from side to side, thereby increasing the angle of the central portion.

Thus, the wall panel 200 and the wall panel 200 adjacent to the wall panel has a triangular projection 220 of the wall panel has an effect that can prevent the occurrence of cracks or cracks due to temperature changes.

4(a) and 4(b) are perspective views of the flow wall panel and a perspective view of the flow wall panel and the flow wall panel combined.

In the case of the triangular protrusion 320 of the swash wall panel and the rectangular protrusion 330 of the swash wall panel, there is an effect capable of flexibly responding to changes in temperature, such as the triangular protrusion 220 of the wall panel described above. In the case of 330), there is an effect of stably fixing the vortex wall panel 300 from the force caused by hydraulic pressure applied to the left and right of the square protrusion.

In order to be formed at a height equal to the height of the reservoir, one or more curved panels 400 may be stacked up and down.

The curved panel 400 is preferably configured to be convex in the direction toward the curved panel 400 before the water collides with the curved panel 400 in order to prevent friction and shoot water flowing in the reservoir.

Accordingly, the flowing water may collide with the surface of the curved panel 400, but there is an effect of smoothly moving along one path in the reservoir without receiving great friction along the curved surface of the curved panel 400.

The curved panel 400 formed as described above is the wall panel 200 and the wall panel in a position where the flow direction of the water flowing through the inflow path 100 is rapidly changed as shown in FIGS. 5(b) and 5(c). It is provided between (200) and between the duct wall panel (300) and the duct wall panel (300) so that the introduced water can flow along the curved surface.

5(b) shows that the curved panel 400 is provided on the front surface between the wall panel 200 and the wall panel 200, and both sides of the curved panel 400 are fixed to the wall panel 200. Can form.

At this time, a bolt 1020 longer than a depth of the fastening groove 1010 may be used so that the bolt 1020 of each fastening portion 1000 protrudes by the same volume.

After the bolt 1020 to which the nut nut 1030 is coupled is inserted into the fastening groove 1010, wait until the thermosetting resin is completely hardened with a curing agent, and then the groove of the intermediate member 1040 in the protruding portion of the bolt 1020 After welding by fitting the wall panel 200 on the intermediate member 1040, the end of the wall panel 200 and the intermediate member 1040 may be welded.

One or more of these fastening parts 1000 may be provided to be formed as shown in FIG. 9(c), and the appearance of the fastening parts inside the wall panel of the actual water storage tank may be as shown in FIG. 10.

Thus, the wall panel 200 can be firmly and easily attached to the inner wall of the water storage tank to form a waterproof layer, and there is an effect of preventing water from entering the fastening groove.

11A and 11B are perspective and front views of a condensed water discharge device installed.

11 (a) and (b), the reservoir may further include a condensed water discharge device 1100.

The condensation water discharge device 1100 may discharge condensation water condensed between the wall panel 200 and the inner wall of the reservoir.

An empty space may exist between the wall panel 200 and the inner wall of the water storage tank, and the moisture contained in the air existing in the empty space may be condensed to form condensation water according to the temperature change of the wall panel 200 or the inner wall of the water storage tank. It can be flowed down along the inner side of the back panel of the wall panel 200 and the triangular projection 220 of the wall panel.

If condensation water is left as it is, mold may be generated, and when the condensation water is lowered to a sub-zero temperature, the condensation water may become bulky in the process of freezing, thereby damaging the wall panel 200.

In order to remove the condensation water, the condensation water discharge device 1100 may include a condensation water channel 1110 and a discharge pump 1120.

The condensation waterway 1110 may be provided below the water storage tank so that condensation water can be collected in one place, and may be formed to be inclined in one direction.

The discharge pump 1120 may suck condensation water collected along the condensation channel 1110 and discharge it to the outside of the reservoir, and may be installed in one or more reservoirs.

Thereby, there is an effect that can easily remove the condensation water.

12(a) and 12(b) are perspective views of a plurality of inflow pipes installed in the inflow path and a rotation induction member provided in each inflow pipe, and perspective views of the rotation induction member.

Referring to (a) and (b) of FIG. 12, the inflow passage 100 of the water storage tank may include an inflow pipe 110.

The inflow pipe 110 may be provided in one or more in the inflow path 100, and the diameter and the protruding length may be formed to increase in length from the surface layer portion to the bottom layer portion along the inflow path 100.

The inlet pipe 110 provided with one or more may be allowed to flow at a constant speed in the horizontal direction regardless of the height from the surface layer portion to the bottom layer portion.

When there is only one inlet pipe 110 in the inflow passage 100, the flow may be formed only up to an adjacent height, so that the flow may not be formed at a position spaced apart from it.

However, when a plurality of inflow pipes 110 are provided, flow can be generated at a constant speed in the horizontal direction regardless of the height from the surface layer portion to the bottom layer portion, thereby preventing water from accumulating.

The inflow passage 100 is inserted into one side of the bottom part and reaches the surface part in a state of being bent to the upper side of the reservoir, and then folded to the lower side so as to reach the bottom part of the reservoir again, the letter U can be connected in an upside down shape, and the inlet pipe 110 is One or more may be provided on one side of the inflow path 100 from the surface layer portion to the bottom layer portion.

Since the water pressure increases as the depth becomes deeper, the diameter and protrusion length of the inflow pipe 110 become longer as it goes from the surface layer portion to the lower layer portion, so that it can flow at a constant speed in the horizontal direction regardless of the water depth.

When one or more plural inflow pipes 110 are provided, friction due to a rotational force rotating in the vertical direction may occur when the flow velocity is different depending on the height, and thus may interfere with smooth flow, and thus flow at a constant velocity in the horizontal direction. It is necessary to configure it.

Accordingly, there is an effect of allowing the water to flow smoothly at a constant speed regardless of the water depth in the reservoir.

The inlet pipe 110 may include a rotation induction member 111.

The rotation inducing member 111 may be provided at the end of the inlet pipe 110, and may have a spiral discharge surface so that water flowing into the reservoir flows into the reservoir by rotating clockwise or counterclockwise.

As an example, as shown in (a) of FIG. 12, a rotation-inducing member 111 in the form of a screw may be included inside the end of the inlet pipe 110.

Through the screw-type rotation inducing member 111 may be introduced into the reservoir in a state having a rotational force in a clockwise or counterclockwise direction.

The flow direction of the water having the rotational force according to the rotation induction member 111 provided in each inlet pipe 110 is preferably installed to be unified in either a clockwise or counterclockwise direction. This is to prevent cancellation.

Accordingly, there is an effect that the chlorine is better mixed than when it is introduced without the rotation inducing member 111 and the flow in the horizontal direction can be better maintained.

13 (a), (b), and (c) are perspective views, cross-sectional views, and cross-sectional views of a sedimentation outlet.

The underwater chin 1210 may have a certain height from the bottom of the reservoir.

The manhole 1220 may be provided before the flowing water reaches the underwater jaw 1210, and a sediment may be introduced by having a certain depth in the bottom direction of the reservoir.

The sediment guide surface 1230 may form an inclined surface in the bottom direction of the reservoir before flowing water reaches the manhole 1220.

The settling furnace 1240 may be connected to one or more manholes 1220.

A sedimentation furnace valve 1241 may be provided at the top of the sedimentation furnace 1240 connected to each manhole 1220.

The sedimentation furnace valve 1241 may block the manhole 1220 and the sedimentation furnace 1240 as necessary, and release the blocking.

The sediment contained in the water flowing through the above structures can be collected in the manhole 1220 and can be discharged to the outside through the sedimentation furnace 1240 by opening the sedimentation furnace valve 1241.

In more detail, the sediment contained in the flowing water can flow to the bottom of the reservoir due to the load while flowing in the reservoir with water, and further descend along the sediment guide surface 1230.

The descended sediment may reach the underwater jaw 1210 by flowing water, but may fail to pass through the underwater jaw 1210 due to the load and descend again to sink to the bottom of the manhole 1220.

The deposited sediment may continue to accumulate in the manhole 1220.

In order to remove the sediment accumulated in the manhole 1220, the sedimentation furnace valve 1241 may be opened to drain water to be removed to the outside through the sedimentation furnace 1240.

Thereby, there is an effect that it is possible to easily remove the sediment inside the reservoir without draining all the water inside the reservoir.

14 is a front view of a pipe pump installed in the reservoir.

When the water channel in the reservoir is long, the speed of the water flowing from the inlet pipe 110 may be gradually slowed, so that the flow may be in a direction different from the flow direction or may be stagnant water.

In particular, in the case of low-floor water, it is preferable to install the pipe pump 1300 so that the water in the low-floor portion flows at a predetermined height at the bottom of the reservoir because the speed decreases due to the influence of water pressure or friction with the floor.

The pipe pump 1300 may receive power from a separately connected pipe pump power supply 1310 and operate simultaneously when water is introduced.

Thereby, there is an effect of smoothly flowing water in the reservoir.
