When the upper portion of the divided piece 330 is bent as described above, for example, rainwater falling downward during rain is prevented from directly entering into the fluid discharge unit 300. In more detail, as described above, most of the rainwater falling in the downward direction is introduced into the fluid discharge unit 300 along the outer wall of the divided piece 330.

In addition, the two sides of the fluid discharge unit 300, the coupling rod 310 is not formed on the two sides of the drain hole 340 is formed in three stages, respectively, as shown in Figure 2 in the drain hole (340) Likewise, the V frame 400 is fitted.

As described above, the two surfaces having the drain hole 340 are preferably formed to face each other. For example, the first stage drain hole 341 on one side and the first stage drain hole 341 'on the other side have different heights. It is formed to have.

When the heights of the drain holes 340 are different from each other, as shown in FIG. 5, rainwater flowing into the fluid discharge unit 300 during the rainfall flows down to the drain hole having the lower height among the two drain holes. .

On the other hand, the V-frame 400 is located at the bottom of the discharge hole 320, the V frame 400 as described in more detail, the V-frame 400 according to a preferred embodiment of the present invention As described above, the drain holes 340 formed in three stages having different heights and both ends are installed to communicate with each other.

It is installed to be located between the 403 ', the two-stage v-frame 402, thereby receiving rainwater that did not flow into the first-stage v-frame 401 of the rainwater flowing from the discharge hole 320. It plays a role.

On the other hand, the above-described three-stage v-frame 403 serves to accommodate the rain water flowing on the outer circumferential surface of the first-stage v-frame 401, whereby the rain portion is prevented from entering the inlet (100).

As shown in the partial enlarged view of FIG. 4A, the drain holes 341, 342, and 343 of the 1,2 and 3 stages into which the 1,2- and 3-stage V-frames 401, 402, and 403 are fitted are provided. If the cross section is formed in a triangular shape, and draws an imaginary line connecting the centers of gravity of the drainage holes 341, 342, and 343 of the 1,2,3 stages as described above, the imaginary line is preferably arranged to form a triangle.

On the other hand, the upper portion of the fluid discharge unit 300, as shown in Figure 2, the closing member 500 is installed, the closing member 500 is wrapped around the edge of the upper portion of the fluid discharge unit 300 The lower end is supported by the coupling rod 310.

Hereinafter, with reference to FIGS. 4 to 5, the flow of air in the exhaust loop according to the preferred embodiment of the present invention is discharged to the atmosphere and the flow of the rainwater when the rainwater is introduced from the outside.

First, referring to FIG. 4A, a flow in which air in the exhaust loop according to the exemplary embodiment of the present invention is discharged is described. When gas is introduced from the lower side of the inlet unit 100, the inlet unit 100 communicates with the inlet unit 100. Gas is introduced into the main body 200.

As the gas introduced into the main body 200 is a gas of a relatively high temperature state in which the resistance of the load resistor installed in the power plant is cooled, such gas is hotter than the gas in the atmosphere, and thus there is a habit to rise.

That is, the gas introduced into the main body 200 flows in three directions of ①, ②, ③ as shown in FIG. 4A.

Gas flowing in the direction of ② of the gas flowing as described above is introduced into the fluid discharge unit 300 through the inlet 100 and the main body 200, the gas introduced as described above is discharge hole 320 To the atmosphere via air.

In addition, the gas flowing in the direction of ①, ③ of the gas flowing as described above is discharged into the space formed between the inner wall of the main body 200 and the fluid discharge unit 300, as shown in FIG.

Next, the flow of rainwater flowing into the fluid discharge unit during the rainfall of the exhaust loop according to the preferred embodiment of the present invention during the rainfall will be described with reference to FIGS. 4B and 5.

When rain falls on the upper side of the fluid discharge unit 300 during rainfall, the rain water is ⑤ and ⑥ which is a space between the discharge hole 320 ④ and the inner wall of the main body 200 and the fluid discharge unit 300. The rainwater flowing into the space formed between the inner wall of the main body 200 and the fluid discharge unit 300 immediately flows into the main body 200 and is discharged to the outside through the lower drain hole 221. .

On the other hand, a portion of the rainwater flowing into the discharge hole 320 as described above is directly introduced into the discharge hole 320, the rest of the divided piece 330 is formed inclined at a predetermined angle (5 ~ 45 degrees) It is introduced into the discharge hole 320 along the inclined surface.

Rainwater flowing into the discharge hole 320 is a state in which the kinetic energy by gravity is stored, when rainwater flows into the discharge hole 320, the rainwater flowing along the inclined surface of the split piece 330 is The kinetic energy stored in the rainwater disappears due to the impact on the divided pieces 330, but the rainwater directly flowing into the discharge hole 320 is in a state in which the kinetic energy is stored.

Rainwater flowing directly into the discharge hole 320 as described above is introduced into the bone portion of the first-stage V-frame 401 installed in the first-stage drain hole 341, the rainwater in which the kinetic energy is stored as described above The first stage V frame 401 is to hit the vertical portion of the valley.

That is, most of the rainwater flowing directly into the discharge hole 320 hits the bone portion of the first stage V frame 401 and simultaneously flows into the first stage V frame 401 as the kinetic energy disappears. Will pop out.

Rainwater splashing out of the first-stage V-frame 401 as described above is introduced into the second-stage V-frame 402 with most of the kinetic energy dissipated, and the rainwater flowed into the second-stage V-frame 402. Since the kinetic energy is largely dissipated while passing through the first stage V frame 401, the phenomenon of rainwater colliding with the second stage V frame 402 is much smaller than that of the first stage V frame 401.

In addition, the three-stage V-frame 403 which is vertically installed in the lower portion of the first-stage V-frame 401 via the second coupling member 360, a portion of the rain water splashing from the two-stage V-frame 402 and Rainwater flowing through the outer wall of the first stage V-frame 401 flows, thereby preventing rainwater from flowing into the inlet 100.

In addition, the two-stage v-frame 402 has a height between the first and the three-stage v-frames 401, 403 vertically arranged up and down, as shown in Figure 4a and 4b and at the same time It is disposed between the three-stage V-frames 401 and 403 and another adjacent one-stage and three-stage v-frames 401 'and 403'.

That is, the rainwater flowing from the discharge hole 320 is prevented from entering the inlet 100 due to the 1,2,3 stage V frames 401, 402, 403.

On the other hand, referring to Figure 5, both ends of the V-frame 400 as described above has a different height, as described above the reason that the height of both ends of the V-frame 400 is different, the above-described drain hole 340 ) Is perforated at different heights.

That is, rainwater flows to one side having a low height among both ends of the V frame 400 and is discharged to the lower drain through hole 221.
