Description

Technical Field

[0001] This utility model relates to a rain cover, and more particularly to a rain cover that penetrates the top of a box. Background Technology

[0002] Generally, direct welding of the cover plate to the pipe leaves gaps, which allow rainwater to easily seep in through thermal expansion and contraction. Furthermore, the vibrations from the pipe during operation are directly transmitted to the welded area, which can easily lead to weld cracking. Traditional sealing structures require disconnecting the pipe before installation, making installation and subsequent maintenance difficult. In addition, planar sealing structures are prone to water accumulation and accelerated corrosion. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a rainproof cover that penetrates the top of the container, thereby solving the problems of rainwater leakage at the pipe hole on the top of the container, easy damage to the welded structure due to vibration, difficulty in installing the seals, and water accumulation and corrosion.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a top-penetrating rain cover for a box, comprising a box with an opening at the top, a pipe disposed within the opening, and a rain cover fitted over the pipe. The rain cover includes a metal flow guide disposed at the opening at the top of the box, a rubber sheet disposed above the metal flow guide, and a clamp disposed on the rubber sheet. The lower part of the metal flow guide is square and covers the flange outside the opening at the top of the box. The upper part has a first circular hole at its center. The upper part has four inclined surfaces forming a truncated pyramid, and the included angle between any two inclined surfaces is an arc surface. Each arc surface has an extension angle at its lower part. The lower part of the rubber sheet is a conical ring, and the upper part is a hollow cylinder. The lower part of the rubber sheet covers the upper part of the metal flow guide, and the coverage area is greater than the diameter of the first circular hole. The clamp is disposed on the outer side of the upper part of the rubber sheet. The pipe passes sequentially through the upper part of the rubber sheet, the first circular hole, and the opening at the top of the box.

[0005] Furthermore, the angle between the inclined surface and the curved surface and the lower horizontal plane is 20°.

[0006] Furthermore, the diameter of the first circular hole is larger than the diameter of the pipe, and the diameter of the hollow cylinder at the top of the rubber sheet is the same as the diameter of the pipe.

[0007] Furthermore, the metal shroud has a first opening on one side that separates the side of the metal shroud, and the first opening is connected by welding.

[0008] Furthermore, the rubber sheet is provided with a second opening for unfolding the rubber sheet. The upper part of the rubber sheet is provided with a first fixing hole on one side of the second opening, and a first fixing block is provided in the first fixing hole on the other side. The lower part of the rubber sheet is provided with a second fixing hole on one side of the second opening, and a second fixing block is provided in the second fixing hole on the other side. The first fixing hole and the second fixing hole are located on the same side of the second opening, and glue is provided between the two opposite sides of the second opening.

[0009] Furthermore, the first fixing hole and the second fixing hole have the same shape, the first fixing block and the second fixing block have the same shape, and the shapes of the first fixing hole and the second fixing hole correspond to the shapes of the first fixing block and the second fixing block, respectively.

[0010] The beneficial effects of the above-mentioned structure of this utility model are as follows: The utility model provides a top-penetrating rainproof cover for a box. Through the metal guide cover covering the flange at the opening on the top of the box, the inclined and arc surfaces guide water, increase the flow rate of rainwater, and prevent water accumulation. Furthermore, the first opening on the metal guide cover and the second opening on the rubber sheet can reduce the installation time by 70%, making installation convenient and realizing the integration of pipe installation without disassembly and efficient drainage. The combination of the rubber sheet and the metal rainproof cover provides a reliable seal and breaks through the pipe diameter limitations and vibration transmission of rigid connections of traditional waterproof covers. At the same time, by replacing the rubber sheet of different sizes, the needs of different pipe diameters can be met without replacing the guide cover. Attached Figure Description

Each arc surface has an extension angle 15 at its lower part. The extension angle 15 is used to prevent rainwater from flowing into the box body from the square corner of the lower part of the metal guide cover 2. The rubber sheet 3 has a conical ring at the lower part and a hollow cylinder at the upper part. The lower part of the rubber sheet 3 covers the upper part of the metal guide cover 2, and the coverage area is larger than the diameter of the first circular hole 6. The clamp 4 is set on the outer side of the upper part of the rubber sheet 3. The pipe 1 passes through the upper part of the rubber sheet 3, the first circular hole 6 and the opening at the top of the box body in sequence. The metal guide cover 2 is made of 1.5mm thick aluminum-zinc coated steel plate.

[0021] The angle between the inclined surface 7 and the arc surface 8 and the lower horizontal surface is 20°, which allows for drainage while accommodating a shorter height.

[0022] The diameter of the first circular hole 6 is larger than the diameter of the pipe 1, and the diameter of the hollow cylinder at the top of the rubber sheet 3 is the same as the diameter of the pipe 1.

[0023] The metal flow guide 2 has a first opening 9 on one side that separates the side of the metal flow guide 2. The first opening 9 extends from the first circular hole 6 through the inclined surface 7 to the lower part of the metal flow guide 2. The first opening 9 is connected by welding.

[0024] The rubber sheet 3 is provided with a second opening 10 for unfolding the rubber sheet 3.

[0027] During installation, pry open the first opening 9 of the metal guide shroud 2, insert the pipe 1 through the first opening 9 into the round hole of the metal guide shroud 2, and cover the flange 5 at the top opening of the box with its lower part. Pinch the first opening 9 closed and perform full welding on the first opening 9. Connect the lower part of the metal guide shroud 2 to the flange 5 at the opening of the box by spot welding. Then pry open the second opening 10 of the rubber sheet 3, insert the pipe 1 through the second opening 10 into the hollow cylinder of the rubber sheet 3, apply glue to the opposite sides of the second opening 10, pinch the second opening 10 closed, place the fixing block in the corresponding fixing hole, and bond the lower part of the rubber sheet 3 to the upper part of the metal guide shroud 2 with acrylic structural adhesive. Finally, use the clamp 4 to tighten the upper part of the rubber sheet 3 onto the pipe 1. After closing, the waterproof rating reaches IP55.

[0028] The beneficial effects of the above-mentioned structure of this utility model are as follows: The utility model provides a top-penetrating rainproof cover for a box.
