The waterproof flow guide device comprises a flow guide plate and a water baffle. The flow guide plate is arranged at the top of the color steel plate, and the top side of the flow guide plate extends to one side of the color steel plate close to the inner side of the parapet wall, and the bottom side of the flow guide plate extends to at least one side of the through hole close to the outer side of the parapet wall, and the width of the flow guide plate is greater than the distance between the two adjacent protrusions of the color steel plate and the through hole.

The water baffle is arranged at the top of the flow guide plate and surrounds the opening. In this way, the rainwater located at one side of the diffusion pipe close to the inner side of the parapet wall will all fall on the flow guide plate and will not fall on the area between the two protrusions adjacent to the through hole of the color steel plate. The rainwater will be blocked by the water baffle during the downward flow, so that the rainwater flows around the through hole of the color steel plate, and the problem of rainwater flowing into the gap between the diffusion pipe and the color steel plate is solved.

[0031] The waterproof flow guide device of the utility model will be described below. Figure 1 And Figure 2 The utility model provides a waterproof flow guide device.

[0032] The top of the parapet wall of the gas power plant steam turbine room is paved by the color steel plate 100, the color steel plate 100 gradually reduces in height from the inner side of the parapet wall to the outer side, and forms the inclined plane of high inside and low outside. A plurality of diffusion pipelines 200 are usually arranged at the position of the parapet wall, and there is a gap between the diffusion pipeline 200 and the color steel plate 100 when the diffusion pipeline 200 passes out from the color steel plate 100 at the top of the parapet wall.

[0033] To prevent rainwater from entering the steam engine room through the above-mentioned gap, glue is usually applied at the gap between the diffusion pipe 200 and the color steel plate 100, and a rain cover 300 is installed at the position where the diffusion pipe 200 is located above the color steel plate 100, but the glued position is prone to cracking, and the rain cover 300 can only block the vertically falling rainwater, and the color steel plate 100 at the top of the parapet wall has a slope, and the rainwater falling on the side of the color steel plate 100 with a higher height will flow into the above-mentioned gap during the downward flow, and then enter the steam engine room.

[0034] The embodiment of the utility model provides a kind of waterproof flow guide device, including deflector 400 and water baffle 420.The waterproof flow guide device is used to be installed at the top of parapet wall, to realize the problem of preventing rainwater from flowing into steam engine room through the gap between diffusion pipe 200 and color steel plate 100.

[0035] Deflector 400 is arranged at the top of color steel plate 100, and can be arranged parallel to the top surface of color steel plate 100.The top side of deflector 400 extends to the side of the inner side of color steel plate 100 close to parapet wall along oblique upward direction, and at the side, the edge of color steel plate 100 is provided with edge trim 110 with L-shaped cross section, and the top side of deflector 400 is pressed on the bottom of edge trim 110, so that rainwater can be prevented from entering the gap between deflector 400 and color steel plate 100.The bottom side of deflector 400 extends to the side of the outer side of through hole close to parapet wall along oblique downward direction, so that deflector 400 can guide rainwater to the side of the outer side of through hole close to parapet wall, so that rainwater no longer passes through through hole area, and there is no case that rainwater enters steam engine room through gap.

[0036] Through hole for penetrating diffusion pipe 200 on color steel plate 100 can be located in the area between adjacent two protrusions, at this time, only rainwater in the area between two protrusions can enter steam engine room through through hole, and rainwater in the area outside two protrusions will not pass through the through hole.Through hole can also penetrate one or multiple protrusions at the same time, at this time, rainwater in the area between two protrusions adjacent to through hole on both sides of through hole can enter steam engine room through through hole, and rainwater in the area outside two protrusions adjacent to through hole on both sides of through hole will not pass through the through hole.

[0037] Therefore, in order to prevent rainwater on the side of the inner side of through hole close to parapet wall from entering the area between two protrusions adjacent to through hole on both sides of through hole, the width of deflector 400 needs to be greater than or equal to the distance between two protrusions, so that deflector 400 can cover the above-mentioned two protrusions to prevent rainwater from entering the area between two protrusions.

[0038] The gap 410 is open at a position close to the bottom side of the deflector 400 and is closed at a position close to the top side of the deflector 400. The side of the gap 410 close to the top side of the deflector 400 is located at the side of the through hole close to the inner side of the parapet and is located in the vertical projection area of the rain shield 300.

[0039] The water baffle 420 is arranged at the top of the deflector 400 and surrounds the gap 410.

[0040] In the installation, the gap 410 of the deflector 400 is aligned with the diffusion pipe 200 to prevent the diffusion pipe 200 from interfering with the installation of the deflector 400, and then the top side of the deflector 400 is coincided with the side edge of the color steel plate 100 close to the inner side of the parapet. At this time, the side of the gap 410 close to the top side of the deflector 400 is located at the side of the through hole close to the inner side of the parapet, so that the through hole is completely exposed, and is located in the vertical projection area of the rain shield 300.

[0041] Since the gap 410 is arranged across the through hole, and the water baffle 420 is arranged at the top of the deflector 400 and surrounds the gap 410, the rainwater upstream of the deflector 400 is blocked by the water baffle 420 when flowing downward, and the rainwater flows around the through hole to prevent the rainwater from entering the turbine room through the through hole.

[0042] The side of the gap 410 close to the top side of the deflector 400 is located at the side of the through hole close to the inner side of the parapet to enable the installation of the deflector 400 and prevent interference with the diffusion pipe 200. The side of the gap 410 close to the top side of the deflector 400 is located in the vertical projection area of the rain shield 300 to prevent the vertically falling rainwater from entering the color steel plate 100 below the deflector 400 through the gap 410, and then entering the turbine room through the through hole when flowing downward along the color steel plate 100.

[0043] In some embodiments, the above-mentioned gap 410 can be a U-shaped opening, the opening of the U-shaped opening faces the bottom side of the deflector 400, and the closed side of the U-shaped opening is a circular arc concentric with the through hole.

[0044] For example, the radius of the circular arc of the closed side of the U-shaped opening is slightly larger than the radius of the through hole, and the circular arc is concentric with the edge of the through hole. Or the radius of the circular arc of the closed side of the U-shaped opening is equal to the radius of the through hole, and at this time the closed side of the U-shaped opening is attached to the diffusion pipe 200.

[0045] In some embodiments, when the edge finishing strip 110 is not arranged on the side of the color steel plate 100 close to the inner side of the parapet wall, a folded edge can be arranged on the top side of the deflector 400, which can be bent in a vertically downward direction. When the top side of the deflector 400 coincides with the side of the color steel plate 100 close to the inner side of the parapet wall, the folded edge can be bent downward to fit the inner side of the parapet wall, so as to prevent rainwater from entering the gap between the deflector 400 and the color steel plate 100.

[0046] In some embodiments, the deflector 400 can be made of aluminum, galvanized steel or stainless steel, with a thickness of 0.6-2.0 mm. For example, the deflector 400 can be a stainless steel plate with a thickness of 1 mm.

[0047] In some embodiments, the water blocking strip 420 can be a plate with a height of 30-80 mm, for example, the height of the water blocking strip 420 can be 30 mm, 40 mm, 50 mm, 60 mm, 70 mm or 80 mm.

[0048] In some embodiments, the deflector 400 and the color steel plate 100 can be connected by self-tapping nails, the water blocking strip 420 and the deflector 400 can be connected by full welding, and sealant can be applied between the water blocking strip 420 and the deflector 400.

[0049] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and description of the present application.
