Description

Technical Field

[0001] This invention belongs to the technical field of port crane machine room structure, and in particular, it relates to a rock wool sandwich panel sealing and drainage structure and assembly method for port crane machine rooms. Background Technology

[0002] The port crane room is built on the seaside dock at a height of more than 30 meters. The environment there is strong wind, rain and sea fog.

[0003] The existing computer room structure includes a base and a box fixed on the base. The box is covered with rock wool boards for noise reduction, sound insulation and heat preservation.

[0004] During use, it was found that due to the environment in which the port crane machine room is located, water inevitably enters the interior of the rock wool board. Long-term water retention inside the rock wool board causes corrosion of the steel plate of the box, resulting in failure of the rock wool board and a short service life.

[0005] The published patents disclose methods such as spraying anti-corrosion paint and anti-salt spray treatment on the box body and base. However, in long-term high humidity and high salt spray environments, this method cannot completely avoid the problem of water ingress into the rock wool board layer and the subsequent problems caused by it. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention provides a sealing and drainage structure and assembly method for rock wool sandwich panels used in port crane machine rooms. This structure is suitable for the high humidity and high salt spray environments of port crane machine rooms, improving the corrosion resistance of the rock wool sandwich panels and extending the service life of the machine room. The technical solution of this invention is as follows:

[0007] As a first aspect of the present invention, it is to provide a sealing and drainage structure for a rock wool sandwich panel for a port crane machine room, including a rock wool sandwich panel, wherein the rock wool sandwich panel includes a middle rock wool panel and two outer panels on both sides, the outer panels are made of metal and are fixedly connected to the rock wool panel by adhesive or screw connection.

[0008] And the enclosure panels;

[0009] Drainage seals;

[0010] L-shaped steel plate;

[0011] Connecting screws pass through the surrounding panel, rock wool sandwich panel, and L-shaped steel plate to secure the rock wool sandwich panel.

[0012] One end of the drainage seal is fixed to the L-shaped steel plate, and the other end contacts the enclosure.

[0013] In a typical implementation, the outer panel of the rock wool sandwich panel is made of thin-walled stainless steel plate.

[0014] In the embodiments provided by the present invention, a converging portion is provided at the bottom end of the rock wool board, and the converging portion is a gradually converging variable cross section, forming an inverted trapezoid or an inverted triangle.

[0015] Preferably, the connecting screw is positioned higher than the starting end of the convergence section.

[0016] Preferably, the bottom ends of the outer panels on both sides of the rock wool sandwich panel are located at the starting end of the convergence section.

[0017] Preferably, the surrounding panel and the L-shaped steel plate are located on both sides of the rock wool sandwich panel for fixing and connecting screws; at the same time, the bottom end of the surrounding panel is lower than the lowest end of the rock wool panel.

[0018] In an embodiment of the present invention, the drainage seal is a baffle, which is inclined and fixed to the L-shaped steel plate at one end, which is higher than the end that contacts the surrounding plate. The side of the baffle welded to the L-shaped steel plate has a bent plane, and the other end is an arc-shaped bend, with the arc surface contacting the surrounding plate.

[0019] Preferably, the baffle is made of metal plate, which relies on its own elasticity to abut against the surrounding plate during assembly. The arc ensures a close fit with the surrounding plate, realizing a closed space and preventing external water from splashing in. The elasticity of the baffle ensures a close fit.

[0020] As a further optimized structure, the arc-shaped bend of the baffle includes at least one bend, and more preferably, three bends, resulting in better sealing.

[0021] As a second aspect of the present invention, a method for assembling the sealing and drainage structure of the rock wool sandwich panel is provided, comprising the following steps:

[0022] First, cut the angle steel along the edge of the L-shaped steel plate and weld it to the L-shaped steel plate along the latter's edge;

[0023] Then, tilt the rock wool board in the rock wool sandwich panel and fix it to the angle steel or steel plate; weld one end of the baffle to the L-shaped steel plate, place the surrounding plate, and fix it with connecting screws through the surrounding plate, rock wool sandwich panel, and L-shaped steel plate.

[0024] As a third aspect of the present invention, a port crane room is provided, comprising a room body enclosed by angle steel and steel plates, and a rock wool sandwich panel sealing and drainage structure fixed to the room wall.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The present invention provides a sealing and drainage structure with a bottom rock wool that converges to a smaller cross-section so that the final residual water is "suspended"; it facilitates ventilation and avoids the problem of corrosion caused by contact with the metal outer panel.

[0027] 2. The arc-shaped baffle designed in this invention has its own elasticity and can fit and press against the side wall to form a sealed space, which prevents external splashing water from entering while draining water; drying measures can be easily taken in the cavity formed, without having to consider other parts (water flows down by gravity and only a small amount remains at the bottom due to adsorption).

[0028] 3. Because there are gaps between the connecting structures of the computer room, ventilation can still be maintained to ensure that the rock wool board is dry. The water at the bottom can accumulate and be discharged in this way, thus extending the service life of the computer room structure.

[0029] 4. This structure is simple, has low implementation cost, and has a significant drainage effect; this structure can significantly extend the service life of the insulation board, and compared with the insulation board with added anti-corrosion materials, it is lower in cost and easier to assemble and use.

[0042] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0043] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0044] As described in the background section, in the prior art, the bottom-enclosed structure allows water to accumulate inside, resulting in corrosion up to 500cm in height, which severely affects the service life of the insulation board.

[0045] Example 1: A sealing and drainage structure for rock wool sandwich panels

[0046] like Figure 1 As shown, the system includes a rock wool sandwich panel 1 fixed to the wall of the computer room, a surrounding panel 2, connecting screws 3, a baffle 4, and an L-shaped steel plate 5. The rock wool sandwich panel 1 includes a central rock wool panel 101 and two outer panels 102 on both sides. The outer panels are made of materials such as aluminum alloy, stainless steel, or color steel, and are fixedly connected to the rock wool panel by adhesive or screws. The outer panels of the rock wool sandwich panel are made of thin-walled stainless steel.

[0047] To enhance the fixing strength, angle steel 6 is installed in the wall of the computer room, and connecting screws 3 pass through the enclosure 2, rock wool sandwich panel 1, angle steel 6 and L-shaped steel plate 5 to fasten the rock wool sandwich panel 1.

[0048] The rock wool sandwich panel sealing and drainage structure provided by the present invention is characterized in that the bottom end of the rock wool board 101 gradually converges, and the converged part 103 is in the shape of an inverted trapezoid or an inverted triangle, or the rounded corners become smaller; the simplest inverted trapezoid is adopted for the convenience of construction.

[0049] The connecting screw 3 is positioned higher than the starting end of the convergence section, and the bottom ends of the outer plates 102 on both sides of the rock wool sandwich panel are located at the starting end of the convergence section.

[0050] The surrounding panel 2 and the L-shaped steel plate 5 are located on both sides of the rock wool sandwich panel 1, and are used to fix the connecting screws 3. At the same time, the bottom end of the surrounding panel 2 is lower than the lowest end of the rock wool panel. One side of the baffle 4 has a bent plane and is welded to the L-shaped steel plate 5. The welding point is indicated by 401 in the figure. The other side is an arc-shaped bend, and the arc surface contacts the surrounding panel 2. The baffle 4 is made of metal plate. During assembly, it relies on its own elasticity to abut against the surrounding panel 2. The arc ensures the fit with the surrounding panel, realizes the closed space, and prevents external water from splashing in. The elasticity of the baffle ensures the fit.

[0051] The baffle 4 is set at an angle, with one end fixed to the L-shaped steel plate 5 higher than the end that contacts the enclosure 2.

[0052] Angle steel 6 is cut along the edge of L-shaped steel plate 5 and welded to L-shaped steel plate 5 along the edge of the latter.

[0053] Water that seeps into the rock wool board flows to the bottom by its own weight, such as... Figure 2 As shown, water accumulates at the convergence point of the rock wool board, with 103 being the water accumulation section. It then falls onto the sloping section with the arc-shaped baffle and continues to flow downwards.

[0054] Ultimately, to prevent water from dripping due to adhesion, the bottom of the rock wool is designed with a variable cross-section to ensure that the last layer of rock wool containing water does not come into contact with any metal materials. This minimizes the risk of metal corrosion from prolonged contact with water. In this structure, the water component is in a "suspended" state, maximizing the lifespan of the structure.

[0055] There is space at the bottom of the rock wool, and within this length, the bottom can be dried by means of air blowing, leaving little moisture. Alternatively, air blowing can be avoided, as the moisture is actually "suspended" and does not come into contact with the metal. Furthermore, the corrosion resistance and lifespan of rock wool itself are far greater than that of steel.

[0056] As a further optimized structure, such as Figure 3 As shown, the arc-shaped bend of the baffle 4 includes at least three bends, resulting in better sealing.

[0057] As another implementation method, such as Figure 4 As shown, the contact position between the baffle 4 and the enclosure 2 is a flat bend, and the end of the flat bend contacts the enclosure 2. This structure is easy to manufacture and further reduces the manufacturing cost.

[0058] As a typical embodiment, the incline height of the converging part 103 is greater than 5cm, and the incline angle is preferably such that it does not contact the side panels 2 and the L-shaped steel plate 5.

[0059] The working principle of this structure is as follows: water from the environment enters the structure from the side or top. Most of the water falls under its own weight and is eventually discharged along the baffle 4. A small portion of the water is adsorbed at the variable cross-section of the rock wool board and gradually dries under the surrounding airflow. Since the baffle 4, the surrounding plate 2, and the L-shaped steel plate 5 enclose the cavity and do not contact the rock wool board, a sealing effect is achieved. On the one hand, this avoids the corrosion that the rock wool board may cause to the metal plate during the gradual drying process. On the other hand, it prevents external water from entering the cavity during strong winds and heavy rains.

[0060] Drainage effect experiment:

[0061] The rock wool sandwich panel in this structure was soaked in water, then placed vertically. Connecting screws 3 were used to fasten the rock wool sandwich panel 1 by passing through the surrounding panel 2, the rock wool sandwich panel 1, the angle steel 6, and the L-shaped steel plate 5. As a result, within 20 hours, all the water flowed out from the bottom under gravity, leaving only a 3cm depth of dampness, and causing no corrosion to the metal outer panel.

[0062] This structure can significantly extend the service life of the insulation board, and is more cost-effective and easier to use compared to insulation boards with added anti-corrosion materials.

[0063] Example 2: An assembly method for a rock wool sandwich panel sealing and drainage structure for a port crane machine room.

[0064] First, cut the angle steel 6 along the edge of the L-shaped steel plate 5 and weld it to the L-shaped steel plate 5 along the edge of the latter;

[0065] Then, a portion of the bottom of the outer panel of the rock wool sandwich panel is cut off, the rock wool board 101 in the rock wool sandwich panel is tilted, and the rock wool sandwich panel is bonded to the angle steel or steel plate; one end of the baffle 4 is welded to the L-shaped steel plate 5, the surrounding plate 2 is placed, and the connecting screws 3 are used to fix the surrounding plate, the rock wool sandwich panel, and the L-shaped steel plate 5.

[0066] Example 2: A port crane machine room

[0067] like Figures 5-8 As shown, the room includes a machine room body formed by angle steel 6 and steel plates. The MM cross-sectional view shows the overall connection between the rock wool board and the machine room wall. The outer panel 102 is further fixed to the rock wool board using pop rivets 7. The rock wool board is fixed to the steel plate of the machine room body using connecting screws 3. The outer wall of the room body adopts the rock wool sandwich panel sealing and drainage structure provided in Example 1.

[0068] Located in a port or dock, this structure is susceptible to water ingress from the sides or top during rain or waves. Figure 7As shown, most of the water flows through the rock wool board under its own weight and is discharged at the baffle 4. The baffle 4, the surrounding plate 2 and the L-shaped steel plate 5 form a cavity that does not contact the rock wool sandwich panel. The lower end of the baffle 4 is folded to facilitate water discharge, but it is not easy for water carried by strong winds to enter, thus preventing water from splashing into the cavity below and achieving a seal.

[0069] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
