Description

Technical Field

[0001] The invention relates to the technical field of ship decks, and in particular to a temporary protective device for ship deck openings. Background Art

[0002] The deck of a ship usually has some holes for the engine piping system and cold air barrel duct to pass through the deck. Specifically, during the loading stage of the slipway or dock, holes will be opened on the deck according to the needs, and the pipes will be installed in the holes on the deck during the later assembly. After the holes are opened, the pipes will not be installed in the holes immediately, but will be arranged and installed in the outfitting stage. During this period, the deck holes are in an unprotected and exposed state, which poses certain safety hazards.

[0003] There are technical solutions for temporary protection of openings on the deck in the prior art. For example, the Chinese utility model patent with the authorization announcement date of October 11, 2019 and the authorization announcement number of CN209479894U discloses a ship deck opening installation protection device, which includes a circular cover plate, a limit ring for limiting the position in the opening on the deck, and a handle is also provided on the upper surface of the cover plate. The deck opening can be protected by placing the device at the opening of the deck. At the same time, from the opening to the outfitting stage, other construction is required for the hull. Usually, the electric welding equipment will be placed on the deck. When the cabin under the deck needs to be welded, the cable needs to be lowered to the lower cabin. In order to save the wiring length, the nearest deck opening is often used to directly lower the cable. In order not to affect the layout of the cable, a U-shaped reserved opening is also opened on the cover of the device. When in use, the cable can enter the lower cabin through the reserved opening.

[0004] However, in the above technical solution, the provision of reserved holes can facilitate the temporary arrangement of cables. However, when it rains or there is water on the deck, water will flow from the openings on the deck into the lower cabin, causing water ingress and rust in the bottom cabin. Of course, in the prior art, aluminum foil tape or three-proof cloth is also used for protection. The aluminum foil tape and three-proof cloth are not firmly fixed on the deck and are easy to fall off. After the aluminum foil tape or three-proof cloth blocks the openings on the deck, the openings cannot be used for cable laying. Summary of the invention

[0005] In view of this, the present invention provides a temporary protective device for a ship deck opening, which is used to solve the problem in the prior art that the deck opening cannot be both waterproof and utilized during the period from the opening on the deck to the installation of the pipeline.

[0010] Furthermore, the annular sealing ring is formed of cured silicone.

[0011] Furthermore, the through hole is a circular hole, and the waterproof cylinder is a cylinder matched with the through hole.

[0012] Furthermore, the distance between the outer periphery of the waterproof tube and the deck opening satisfies: not less than 10 mm.

[0013] Furthermore, the outer circle size of the cross section of the waterproof tube is the same as the size of the deck opening, and the waterproof tube is welded to the connecting plate.

[0014] Furthermore, the connecting plate is a square plate.

[0015] Furthermore, the minimum distance between the outer edge of the shielding plate and the outer circumference of the waterproof tube is not less than 30 mm.

[0029] In the embodiment 1 of the temporary protective device for opening of ship deck (hereinafter referred to as protective device) of the present invention:

[0030] Reference Figure 1 , which is a schematic diagram of the structure of the protective device in the present invention. As shown in the figure, the protective device comprises a connecting plate 1, a waterproof cylinder 2 located above the connecting plate 1, and a shielding plate 3 arranged at the end of the waterproof cylinder 2. The connecting plate 1 is used to be fixedly connected to the deck 6 and used to shield the deck opening.

[0031] Specifically, Figure 2 As shown, the connecting plate 1 is a square plate, and the openings on the deck 6 include both round holes and square holes. Usually, the size of the deck openings is mostly between 80mm-350mm. In this embodiment, the connecting plate 1 is selected as a 400mm*400mm square plate, which can cover both square holes and round holes. Since a connecting plate 1 of a specific size is selected, when the size of the connecting plate 1 is too large and causes interference with the surrounding parts 7, it can be temporarily cut. Of course, it is also possible to cut off the four corners on site to form an octagonal connecting plate 1 or cut it into a circular connecting plate 1. The size of the connecting plate 1 is relatively large, and there may be other parts above or below the deck 6 that cause interference with the connecting plate 1. The connecting plate 1 can be placed above the deck 6. It can also be as follows Figure 3 As shown, the connecting plate 1 is installed under the deck 6, and the upper plate surface of the connecting plate 1 is attached to the lower surface of the deck 6. The scheme is selected according to the surrounding environment of the deck opening on site. Alternatively, in other embodiments, the connecting plate can also be set as a circular plate, as long as the diameter of the circular plate is larger than the diagonal size of the square hole, the circular plate can also cover the square hole on the deck.

[0032] The connecting plate 1 needs to be fixedly connected with the deck 6, and welding is adopted in this embodiment. Since the protective device only plays a protective role before the pipeline is installed, when the pipeline is installed, the protective device will hinder the pipeline, resulting in the inability to install the pipeline, so the protective device needs to be removed before the pipeline is installed. In order to facilitate disassembly, spot welding is adopted between the connecting plate 1 and the deck 6. When the connecting plate 1 is placed above the deck 6, the deck 6 itself can support the connecting plate 1, so welding only plays a fixing role, and a smaller number of spot welding can be used at this time. When the connecting plate 1 is located below the deck 6, the fixing and support of the protective device need to be provided by welding points, especially considering the safety when people accidentally step on it, so a larger number of spot welding can be used. Specifically, in this embodiment, when the connecting plate 1 is located above the deck 6, the entire periphery is spot welded at four points, each spot weld is 5mm long, and when the connecting plate 1 is located below the deck 6, the entire periphery is spot welded at eight points, each spot weld is 10mm long. Of course, in other implementations, the number of spot welds and the welding length of each spot weld may be adaptively adjusted according to on-site requirements.

[0033] like Figure 2 and Figure 3 As shown, the disassembly is facilitated by spot welding, but there will be a gap between the plate surface of the connecting plate 1 and the plate surface of the deck 6, which will cause water leakage. Therefore, an annular sealing ring 5 arranged around the deck opening is also provided between the connecting plate 1 and the deck 6. For the convenience of construction, the annular sealing ring 5 in this embodiment is formed by cured silicone, that is, an additional gluing operation is required. The gluing operation is often performed on the upper surface of the deck 6. At this time, the convenient place for gluing is the intersection of the connecting plate 1 and the deck 6. Since the connecting plate 1 can be located above or below the deck 6, when the connecting plate 1 is located below the deck 6, the gluing operation is performed along the inner peripheral surface of the deck opening. When the connecting plate 1 is located above the deck 6, the gluing operation is performed along the outer peripheral surface of the connecting plate 1. It should be noted that no matter which gluing method is used, the gluing trace should be kept continuous and uninterrupted. Of course, in other embodiments, an O-ring can also be provided between the deck 6 and the connecting plate 1 to achieve sealing through the sealing ring.

[0034] In order to facilitate the connection between the upper and lower spaces of the deck 6, a through hole connecting the upper and lower spaces of the deck 6 is provided on the connecting plate 1, and the existence of the through hole will lead to the risk of water leakage. Therefore, a waterproof cylinder 2 is also arranged on the connecting plate 1. The waterproof cylinder 2 is an annular cylinder and is arranged vertically. The tube mouth of one end of the waterproof cylinder 2 is connected to the connecting plate 1 and covers the through hole on the connecting plate 1, so that water cannot easily flow from the through hole to the inside of the cabin. In order to facilitate installation, the waterproof cylinder 2 is a cylinder, and the through hole is a circular hole. The waterproof cylinder 2 is inserted into the through hole. At this time, the area covered by the waterproof cylinder 2 just coincides with the coverage area of ​​the through hole, and the connection and sealing of the two are facilitated by fully welding the outer periphery of the waterproof cylinder 2 and the connecting plate 1. Of course, in other embodiments, the coverage range of the waterproof cylinder can also be made larger than the area of ​​the through hole. At this time, the mouth of the waterproof cylinder is welded on the plate surface of the connecting plate.

[0035] The upper opening of the waterproof cylinder 2 forms a vertically penetrating opening. In order to prevent rainwater from entering the waterproof cylinder 2, a shielding plate 3 is hingedly provided at the upper end of the waterproof cylinder 2. The shielding plate 3 is a metal plate with a covering area larger than the cross-sectional area of ​​the waterproof cylinder 2. Specifically, in this embodiment, the shielding plate 3 is a circular cover plate, and the size of the shielding plate 3 is at least 30 mm larger than the size of the waterproof cylinder 2, thereby ensuring a better shielding effect. The difference in size between the shielding plate 3 and the waterproof cylinder 2 can also be 40 mm or 50 mm.

[0036] When temporary protection is required for the opening on the deck 6, first select the waterproof tube 2 and the connecting plate 1 of appropriate size, weld the waterproof tube 2 and the connecting plate 1 together, and keep the weld fully welded to isolate rainwater. The connecting plate 1 needs to match the shape of the deck 6 to achieve the connection between the connecting plate 1 and the surface of the deck 6. Since both the waterproof tube 2 and the connecting plate 1 need to be welded, in order to ensure the welding quality and the protection quality, they are both steel plates with a thickness of not less than 3 mm. Then place the connecting plate 1 at the opening of the deck 6 and weld the connecting plate 1 to the deck 6. Finally, hinge the shielding plate 3 on the waterproof tube 2 to achieve the installation of the protective device.

[0037] In the embodiment 2 of the temporary protective device for opening of ship deck (hereinafter referred to as protective device) of the present invention:

[0038] In this embodiment, the installation form of the shielding plate 3 is mainly changed, and the remaining structural features are the same as those in Embodiment 1. Specifically, Figure 4As shown, the shielding plate 3 is welded and fixed at the upper end of the waterproof cylinder 2. Since the upper end cover of the waterproof cylinder 2 can no longer be opened at this time, it is necessary to open an additional hole to facilitate the passage of cables or other tools or parts. The fixed connection here means that the two parts will not rotate or slide relative to each other after being connected, and the relative positions of the two parts remain unchanged. In this embodiment, a connecting port 21 is opened on the upper side of the waterproof cylinder 2, and the upper and lower spaces of the deck 6 are connected through the connecting port 21. Since the shielding plate 3 extends for a long length, even if there is rain, it will not enter the interior of the waterproof cylinder 2. Since the connecting port 21 is opened on the upper part of the waterproof cylinder 2, its lower part is fixedly connected to the connecting plate 1. At this time, the connecting port 21 has a certain height, and the water on the deck 6 and the connecting plate 1 will not flow into the connecting port 21, thereby realizing the connection of the upper and lower spaces of the deck 6 when needed and also realizing the watertightness of the upper and lower spaces of the deck 6.

[0039] It should be clear that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
