Description

Technical Field [0001] The present invention relates to a rectangular water tank having an integral structure of a manhole with a manhole and a sidewall having improved durability,

The present invention relates to a rectangular water tank, and more particularly, it relates to a rectangular water tank, which is installed to be integrally coupled to a side wall of a sidewall and is formed of a bending panel, so that a load bearing capacity is excellent and a manhole through which a worker can pass can be formed And a rectangular water tank in which a manhole can be moved and a manhole and a through hole are arranged so that stored water flows in a zigzag manner.

Typically, a flow-through wall in a water tank is a wall that guides the flow of water, preventing water from stagnating, allowing water to flow at a constant rate, and increasing the contact time between water and chlorine.

For example, as shown in Figs. 1 and 2, the flow-through walls 3 are alternately installed in the side walls 5 and 6 of the rectangular water tank 1. Fig. The width w1 of the flow-through wall 3 is smaller than the width w2 of the water tank 1. Thus, the water introduced through the inlet 8 flows in a zigzag manner to the left and right through the portion without the flow-through wall 3, and then is discharged through the outlet 9. In FIGS. 1 and 2, arrows indicate the direction in which water flows.

As described above, the flow-through wall 3 flows zigzag water in left and right directions, thereby allowing sequential water flow without generating stagnation water and short-circuit flow, and increasing stirring operation and staying value to increase the time for foreign matter precipitation And increases chlorine disinfection effect.

However, there is a problem in that the flow-through wall 3 only flows water left and right zigzag and can not flow zigzag up and down.

On the other hand, the side wall of the rectangular water tank 1 is made by combining a plurality of panels. The panels include stainless steel panels, synthetic resin panels, and composite panels. In order to reduce the manufacturing cost, it is desirable to reduce the thickness as much as possible. However, considering the water pressure, wind load, and earthquake load acting on the side walls, .

In addition, when an earthquake occurs, the water inside the water tank is swung due to an earthquake. Such swelling is necessary to prevent the water tank from damaging it. Although the flow-through wall 3 can alleviate the swaying to some extent, the flow-through wall 3 can be transmitted through the portion without the flow-through wall 3, which is not effective.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rectangular water tank capable of effectively supporting a load (water pressure, etc.) because the side walls and the guiding wall are integrally structured and the guiding wall is formed of a bending panel.

Another object of the present invention is to provide a rectangular water tank through which a worker can move through a manhole formed in a cir- cumferential wall.

It is still another object of the present invention to provide a rectangular water tank in which stored water flows in a zigzag manner up and down and left and right due to manhole holes and through holes of a flow-through wall.

It is still another object of the present invention to provide a rectangular water tank in which the flow wall not only guides the flow of water but also acts as a wave plate.

In order to solve the above problems, the rectangular water tanks 100 and 400 according to the preferred embodiment of the present invention are arranged at predetermined intervals in the first and second storage spaces A and B along the longitudinal direction (x direction) (130) and (140) installed therein.

Both ends of the first and second cir- culating walls 130 and 140 are coupled to the side wall 113 and the partition 115 or the side wall 114 and the partition 115 in an integrated manner. Therefore, the first and second cir- culating walls 130 and 140, the side walls 113 and 114, and the partition 115 can have an integrated structure to support the load.

A manhole 132 and a plurality of through holes 134 and 136 are formed in the first and second cir- culating walls 130 and 140. The manhole hole 132 is formed at the lower portion of the first and second cryogenic walls 130 and 140 with a size that the operator can pass through.

The through holes 134 may be formed only on the side where the manhole holes 132 are present in the first and second cir- culating walls 130 and 140. This structure flows in the first and second storage spaces A and B Causes the water to flow in a zigzag from side to side. As an alternative to such a structure, the through holes 134 may be formed at predetermined intervals over the entire width direction of the first and second cirrus walls 130 and 140.

The through holes 134 are formed in only one of the upper and lower portions of the first and second flow walls 130 and 140 in the first and second flow walls 130 and 140, The through-holes 136 having a small size may be formed only on the other one of the upper and lower portions of the first and second flow-through walls 130 and 140. This structure allows the water flowing in the first and second storage spaces A and B to flow vertically and zigzag.

The inlet port 120 supplies water to the first storage space A and the connection port 122 is formed in the partition 115 so that the water in the first storage space A moves into the second storage space B , And the water outlet 126 discharges the water in the second storage space B to the outside. In the rectangular water tanks 100 and 400, the inlet and outlet ports 120 and 126 and the connection port 122 are located on opposite sides of the water tank so that the flow distance of water is long.

The water flowing into the first storage space A through the inlet 120 moves along the -x direction and then moves to the second storage space B through the connector 122. Then, (B) and then discharged through the outlet port (126).

The rectangular water tanks 200 and 500 according to another preferred embodiment of the present invention are different from the rectangular water tanks 100 and 400 in that the inlet ports 120 and 124 and the outlet ports 121 and 125 ) Are located on opposite sides of the water tank.

Specifically, the water inlet 120 supplies water to the first storage space A, and the water supplied to the first storage space A passes through the first and second cir- culating walls 130 and 140 while being zigzag And then discharged to the outside through the outlet 121. The inlet 124 supplies water to the second storage space B and the water supplied to the second storage space B flows in a zigzag manner while passing through the first and second drift walls 130 and 140. And then discharged to the outside through the outlet 125.

The first and second flow walls 130 and 140 installed in the first storage space A and the first and second flow walls 130 and 140 installed in the second storage space B can be effectively It is preferable that they are provided at positions corresponding to each other.

In the above description, the inside of the rectangular water tank is divided into two storage spaces (A) and (B). However, only one storage space may be formed inside the rectangular water tank. That is, in the rectangular water tank 300, the first and second flow-inducing walls 130 and 140 may be repeatedly installed alternately along the longitudinal direction in a single storage space formed in the longitudinal direction (x direction). In this case, since both ends of the first and second cir- culating walls 130 and 140 are integrally connected to the side walls 113 and 114, the first and second cir- culating walls 130 and 140 and the side wall 113, (114) have an integral structure to support the load.

The first and second cir- cuit walls 130 and 140 are formed by bending the metal panel to increase load bearing capacity so that the front and rear protrusions in the height direction of the first and second cir- culating walls 130 and 140 Are alternately formed. The front protruding portion and the rear protruding portion are continuous from one end to the other end in the width direction of the first and second flow walls 130 and 140.

The reinforcing frame 150 may be coupled to the rims of the first and second cir- cuit walls 130 and 140. The reinforcing frame 150 is formed in a rectangular shape. The reinforcing frame 150 cooperates with the first and second flow walls 130 and 140 to support the load and prevent the first and second flow walls 130 and 140 from being bent by the flowing water.

The rectangular water tank 600 according to another preferred embodiment of the present invention is characterized in that the inlet 120 is formed on the bottom 616 and at least three or more flow walls 630, So as to form the intake space C1. Each of the flow-through walls 630, 130, and 640 has one end coupled to the side wall and the other end coupled to the center portion of the other flow-through walls 630, 130, and 640, Is coupled to the flow-through wall 640 and the end of the flow-through wall 640 is coupled to the flow-through wall 630.

The manhole holes 132 are formed on both sides of the manhole walls 630 and the through holes 134 and 136 are formed at predetermined intervals over the entire section of the manholes 630. The manholes 130 are formed at one side The manhole hole 132 and the through hole 134 and the manhole hole 132 and the through hole 134 do not exist on the other side and the manhole hole 132 and the through holes 134 and 136 none.

The water in the intake space C1 is discharged to the space C2 only through the manhole hole 132 and the through holes 134 and 136 of the flow-through wall 630 and the water in the space C2 flows through the through hole and the manhole (C3) and (C4) through the outlet port (126), and then discharged to the outside through the outlet port (126).

The square water tank according to the present invention has the following effects.

First, since the side walls and the guiding wall are integrally formed and the guiding wall is formed of the bending panel, the load (water pressure, etc.) can be effectively supported.

Second, the operator can move through the manhole formed in the wall.

Third, the stored water flows in a zig-zag manner up and down and left and right due to the manhole and the through hole formed in the flow-through wall, thereby preventing the generation of stagnation water and short-circuit water, thereby enabling sequential water flow, Increasing the retention value can increase the time for foreign matter precipitation and the chlorine disinfection effect.

Fourth, the flow wall not only guides the flow of water but also acts as a wave plate. As a result, damage to the water tank due to an earthquake can be eliminated or reduced.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely examples of the present invention and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.

In the present specification, the term 'rectangular water tank' refers to a water tank in which a water storage space of a rectangular parallelepiped or a cube is formed by side walls, floor, and ceiling.

First Embodiment

FIG. 3 is a perspective view showing a rectangular water tank according to the first embodiment of the present invention, and FIG. 4 is a plan view showing a flow of water in the water tank.

Referring to the drawings, a rectangular water tank 100 includes side walls 111, 112, 113 and 114, a floor, a ceiling, and a partition wall 115. The side walls 111, 112, 113 and 114 and the bottom and the ceiling form a rectangular parallelepiped internal space and the partition 115 connects the internal space to the first and second storage spaces A and B ). In the first and second storage spaces A and B, the first and second flow-through walls 130 and 140 are installed.

The first and second storage spaces A and B have a rectangular parallelepiped shape elongated along the longitudinal direction (± x direction). The inlet port 120 and the outlet port 126 are formed in the side wall 111 and the connection port 122 is formed in the partition wall 115. The connection port 122 is formed on the opposite side of the mouth 120 from the mouth 120.

Specifically, the inlet 120 supplies water to the first storage space A, the water supplied to the first storage space A is moved in the -x direction, The water flowing into the second storage space B is moved in the + x direction, and then is discharged to the outside through the water outlet 126. Accordingly, the water supplied through the inlet 120 moves along the path of the ⊂ shape until it is discharged through the outlet 126.

In the first storage space A, the first and second flow-through walls 130 and 140 are alternately installed along the longitudinal direction (± x direction), and are integrally coupled to the side wall 113 and the partition 115 do. In the second storage space B, the first and second drift walls 130 and 140 are alternately disposed along the longitudinal direction (± x direction) and are integrally coupled to the side wall 114 and the partition 115 Respectively.

The first and second cir- cuit walls 130 and 140 are coupled to the side walls 113 and 114 so as to connect the partition 115 to each other. It also plays a role. 2, since the width w1 of the flow-through wall 3 is smaller than the width w2 of the water tank 1, the wobble can be easily transmitted laterally. However, in the present invention, Since the first and second cir- cuit walls 130 and 140 are coupled to connect the side walls 113 and 114 to the partition 115, the delivery of the contents can be prevented or reduced.

The first and second flow walls 130 and 140 of the first storage space A and the first and second flow walls 130 and 140 of the second storage space B are installed at positions corresponding to each other. This structure can efficiently transmit (disperse) the load.

The first flow-through wall 130 is formed by repeatedly bending a thin-walled metal panel (for example, a stainless steel panel), as shown in Figs. 5A and 5B. Therefore, the first protruding portion and the rear protruding portion are alternately and repeatedly formed in the height direction (z direction) in the first flow-through wall 130. [ The front projecting portion and the rear projecting portion continuously extend from one end to the other end in the width direction (y direction) of the first flow-through wall 130. The first cryogenic wall 130 may be coupled to the side walls 113 and 114 and the partition 115 by welding or the like.

When the first flow-inducing wall 130 is repeatedly bent, it is possible to solve the problem that the first flow-inducing wall 130 is bent due to the flow of water, The load (water pressure, etc.) can be effectively supported and transmitted.

The reinforcing frame 150 may be coupled to the rim of the first flow-through wall 130. That is, in the present invention, both end portions of the first flow-through wall 130 are integrally installed so as to be directly coupled to the side wall 113 and the partition 115 or to be directly coupled to the side wall 114 and the partition 115, The reinforcing frame 150 is coupled to the rim of the first cryogenic wall 130 so that the reinforcing frame 150 is coupled to the side wall 113 and the partition wall 115 or the side wall 114 and the partition wall 115 The first wall 130 and the reinforcement frame 150 can support the water pressure (load) and prevent the first wall 130 from being warped.

The reinforcing frame 150 has a rectangular shape, and the first flow-through wall 130 is welded to the inside of the square. The reinforcing frame 150 may be joined to the side walls 113 and 114 and the partition 115 by welding or the like.

A manhole hole 132 and a plurality of through holes 134 are formed in the first cryogenic wall 130. The manhole hole 132 and the through hole 134 are formed only on the left side (the left side in FIG. 5A) with respect to the center of the first flow-through wall 130, and are not formed on the right side.

The manhole hole 132 is a passage for an operator to move for a maintenance work or a cleaning work, and is formed in a circular shape having a size enough for an operator to pass through, preferably about 600 mm to 900 mm in diameter. In this way, in the water tank 100, the first and second fluid flow passages 130 and 140 are installed to connect the side walls 113 and 114 to the partition wall 115 to support the load, And has a manhole hole 132. It is preferable that the manhole hole 132 is formed in a circular shape because the concentration of stress around the manhole 132 is alleviated as compared with the case where the manhole hole 132 is formed in a quadrangular shape, a pentagonal shape or an elliptical shape.

On the other hand, the manhole hole 132 is advantageous in that the structure of the manhole 132 is much simpler than that of a separate opening and closing door (not shown) for a worker and an advantage of being able to generate a vortex .

The manhole hole 132 is formed in the lower portion of the first flow-through wall 130 because it is the minimum height that the operator can lean and pass through. If the manhole hole 132 is formed on the upper side, it is difficult for an operator to pass through.

The through hole 134 is a circular hole formed to penetrate the first flow-through wall 130, and serves as a water passage.

The second flow-through wall 140 is installed between the first flow-through walls 130. Therefore, the first and second cryogenic walls 130 and 140 are alternately arranged along the longitudinal direction (x direction).

The second cryogenic wall 140 is different from the first cryogenic wall 130 except that the positions of the manhole 132 and the through hole 134 are different from each other. The configuration is the same. Therefore, as shown in FIGS. 6A and 6B, the second flow-through wall 160 has a structure in which a thin metal panel (for example, a stainless steel panel) is repeatedly bent, The structure in which the front protruding portion and the rear protruding portion are formed in the first flow-through wall 140 is the same as that in the first flow-through wall 130.

The second flow-through wall 140 may be integrally coupled to the side wall 114 and the partition wall 115 to support the water pressure (load) at both ends thereof. However, the reinforcement frame 150 may be reinforced (Load) together with the frame 150, which is the same as in the first flow-through wall 130. [0064]

The manhole hole 132 and the through hole 134 of the first cryogenic wall 130 are formed only on the left side (left side in FIG. 5A) with respect to the center of the first cryogenic wall 130 and not on the right side, The manhole hole 132 and the through hole 134 of the second cryogenic wall 140 are formed only on the right side (right side in FIG. 6A) with respect to the center of the second cryogenic wall 140, and are not formed on the left side. Thus, the stored water flows staggered left and right as shown in Fig.

A configuration in which the water supplied through the inlet 120 moves along the path of the ⊂ shape until the water is discharged through the outlet 126 and the configuration in which the water flows through the manhole 132 and the through hole 134 in a zigzag The composition can increase the agitation action and the retention value to increase the time and chlorine disinfection effect for foreign matter precipitation, and the sequential water flow is possible, thereby preventing the generation of stagnation water and short circuit.
