Description

Technical Field

[0001] This utility model relates to the field of ship hatch covers, and more specifically, to a sealing structure for ship hatch covers. Background Technology

[0002] Ship hatch cover sealing is one of the core technologies in marine engineering to ensure the safety of the cabin environment and the reliability of equipment operation. Its core function is to prevent external media such as water, air, and pollutants from entering the cabin (such as cargo hold, engine room, living quarters, etc.) through a sealing structure, while preventing the leakage of internal media (such as oil and gas, condensate). Existing ship hatch covers lose their sealing effect due to deformation of the sealing unit caused by pressure on the hull or hatch cover. Uneven gaps are prone to occur between the hatch cover and the hull flange surface. Traditional rigid sealing structures cannot compensate for gap changes, causing rainwater and seawater to seep into the cabin. Traditional sealing structures rely on multiple bolts for tightening, and each bolt hole must be aligned and tightened during installation, which takes too long to install a single hatch cover. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for the sealing structure of a ship hatch.

[0004] According to a first aspect of this utility model, a sealing structure for a ship hatch cover is provided, comprising: a hatch flange, wherein a sealing mechanism and an installation mechanism are provided on the hatch flange, the sealing mechanism includes a ship hatch cover body, the ship hatch cover body is mounted above the hatch flange, a hatch chamber is formed inside the hatch flange, an assembly groove is formed inside the hatch flange, the assembly groove has a stepped structure, a stepped sealing ring is fixedly connected to the bottom end of the ship hatch cover body, the bottom of the stepped sealing ring has a stepped structure, an airbag groove is formed inside the ship hatch cover body, an inflatable sealing bladder is filled inside the airbag groove, and the inflatable sealing bladder inside the airbag groove is connected to a pressure sensor through a miniature air pump.

[0005] Preferably, a handle is fixedly connected to the upper end of the ship hatch body.

[0006] Preferably, the installation mechanism includes a mounting base, which is fixedly connected to the outer wall of the ship's hatch body. The mounting base has a slot inside. A fixing post is fixedly connected to the upper end of the hatch flange. A limiting rod is inserted through the fixing post. One end of the limiting rod is inserted into the slot inside the mounting base. A fixing ring is fixedly connected to the inner wall of the fixing post. The limiting rod is slidably disposed inside the fixing ring. A spring is wound around the surface of the limiting rod. One end of the spring is connected to the fixing ring.

[0007] Preferably, a slider is fixedly connected to the side wall of the limiting rod, and the slider is slidably disposed inside the slide groove, which is opened inside the fixed column.

[0008] Preferably, a positioning rod is fixedly connected to the bottom end of the mounting base, the positioning rod is engaged inside the positioning groove, and the positioning groove is opened inside the cabin flange.

[0009] Preferably, a reinforcing fastener is fixedly connected to the outer wall of the ship hatch body, the reinforcing fastener is set at a 90-degree angle to the mounting base, and a positioning rod is fixedly connected to the bottom end of the reinforcing fastener.

[0010] 1. This utility model connects the ship hatch cover body to the hull flange through the cooperation of the ship hatch cover body, hull chamber, assembly groove, stepped sealing ring, and airbag groove. The sealing unit at the bottom of the ship hatch cover body is a stepped sealing ring, which is adapted to the stepped assembly groove on the ship hatch cover body. This avoids the failure of the upper stepped sealing ring due to compression deformation, which would directly lead to the failure of the entire sealing unit. The bottom stepped sealing ring can still achieve a sealing effect. In addition, the inflatable sealing bladder inside the airbag groove is connected to a pressure sensor through a micro air pump to monitor the gap in real time and automatically replenish the air. Deformation of the hull flange hatch opening causes a gap in the main seal, which improves the overall sealing performance of the device. The sealing structure of this ship hatch cover can use a stepped sealing unit to achieve multi-layer sealing, avoiding the situation where the upper end of the sealing unit fails due to compression, which would cause the entire unit to fail. This improves the practicality and sealing performance of the device.

[0011] 2. This utility model, through the cooperation of a mounting base, a fixing column, a limiting rod, a spring, a fixing ring, and a slider, connects the ship hatch cover to the hull flange without using bolts. During installation, pulling the limiting rod moves it away from the mounting base, placing the ship hatch cover body downwards, causing the mounting base to engage with the hull flange. At this time, the spring is in a compressed, stored state. Releasing the limiting rod allows the spring force to drive the limiting rod into the slot inside the mounting base. The spring's pushing force secures the mounting base and the ship hatch cover body above the hull flange, eliminating the need for multiple sets of bolts for limiting installation. This achieves a sealing structure for the ship hatch cover that does not rely on bolts for assembly, avoiding the problem of traditional sealing structures relying on multiple bolts for tightening, which requires aligning and tightening bolt holes one by one during installation, resulting in excessive time. This improves the practicality and convenience of the device.

[0020] like Figure 1-4 As shown, one embodiment of this utility model is provided: A sealing structure for a ship hatch cover. The hatch flange 111 used in this application is a product that can be purchased directly from the market. Its principle and connection method are existing technologies well known to those skilled in the art. Includes: a hull flange 111, a sealing mechanism 2 and an installation mechanism 3 on the hull flange 111, the sealing mechanism 2 includes a ship hatch cover body 211, the ship hatch cover body 211 is mounted on top of the hull flange 111, a hull chamber 212 is opened inside the hull flange 111, an assembly groove 213 is provided inside the hull flange 111, the assembly groove 213 has a stepped structure, a stepped sealing ring 214 is fixedly connected to the bottom end of the ship hatch cover body 211, the bottom of the stepped sealing ring 214 has a stepped structure, an airbag groove 215 is opened inside the ship hatch cover body 211, the airbag groove 215 is filled with an inflatable sealing bladder, and the inflatable sealing bladder inside the airbag groove 215 is connected to a pressure sensor through a miniature air pump; When using the sealing structure of this ship hatch cover, the ship hatch cover body 211 is connected to the hatch flange 111. The sealing unit at the bottom of the ship hatch cover body 211 is a stepped sealing ring 214, which is adapted to the stepped mounting groove 213 on the ship hatch cover body 211. This avoids the failure of the upper stepped sealing ring due to compression deformation, which would directly lead to the failure of the entire sealing unit. The stepped bottom sealing ring can still achieve a sealing effect. In addition, the inflatable sealing bladder inside the air bladder groove 215 is connected to a pressure sensor through a micro air pump to monitor the gap in real time and automatically replenish the air. The deformation of the hatch opening of the hatch flange 111 causes a gap in the main seal, which improves the overall sealing performance of the device.

[0021] A handle 216 is fixedly connected to the upper end of the ship hatch body 211.

[0022] The mounting mechanism 3 includes a mounting base 311, which is fixedly connected to the outer wall of the ship hatch body 211. The mounting base 311 has a slot inside. A fixing post 312 is fixedly connected to the upper end of the hatch flange 111. A limiting rod 313 is provided through the fixing post 312. One end of the limiting rod 313 is inserted into the slot inside the mounting base 311. A fixing ring 316 is fixedly connected to the inner wall of the fixing post 312. The limiting rod 313 is slidably disposed inside the fixing ring 316. A spring 315 is wound around the surface of the limiting rod 313. One end of the spring 315 is connected to the fixing ring 316. When using the sealing structure of this ship hatch cover, the connection between the ship hatch cover and the hull flange 111 is no longer made with bolts. During installation, pull the limiting rod 313 to move it away from the mounting seat 311, and place the ship hatch cover body 211 downwards so that the mounting seat 311 engages with the hull flange 111. At this time, the spring 315 is in a compressed and stored state. Release the limiting rod 313, and use the elastic force of the spring 315 to drive the limiting rod 313 into the slot inside the mounting seat 311. The pushing force of the spring 315 can make the mounting seat 311 and the ship hatch cover body 211 securely above the hull flange 111, eliminating the need for multiple sets of bolts for limiting installation.

[0023] The side wall of the limiting rod 313 is fixedly connected to a slider 317, which is slidably disposed inside the slide groove 318, which is opened inside the fixed post 312. When the limiting rod 313 moves, the slider 317 moves synchronously inside the slide groove 318, thereby limiting the limiting rod 313 and making its sliding more stable.

[0024] A positioning rod 319 is fixedly connected to the bottom of the mounting base 311. The positioning rod 319 is engaged inside the positioning groove 320, which is located inside the cabin flange 111. When the mounting base 311 is engaged with the upper end of the cabin flange 111, the positioning rod 319 is inserted into the positioning groove 320, which plays a positioning and fastening role, making the installation more convenient.

[0025] A reinforcing fastener 321 is fixedly connected to the outer wall of the ship hatch body 211. The reinforcing fastener 321 is set at a 90-degree angle to the mounting base 311. A positioning rod 319 is fixedly connected to the bottom end of the reinforcing fastener 321. Two sets of reinforcing fasteners 321 are set in the 90-degree direction of the two sets of installation mechanisms 3, so that they form a corresponding cross structure with the installation mechanism 3, which improves the installation strength and makes the ship hatch cover body 211 more secure when installed on the hull flange 111.

[0026] Working principle: When using the sealing structure of this ship hatch cover, the ship hatch cover body 211 is connected to the hatch flange 111. The sealing unit at the bottom of the ship hatch cover body 211 is a stepped sealing ring 214, which is adapted to the stepped mounting groove 213 on the ship hatch cover body 211. This avoids the failure of the upper stepped sealing ring due to compression deformation, which would directly lead to the failure of the entire sealing unit. The stepped bottom sealing ring can still achieve a sealing effect. In addition, the inflatable sealing bladder inside the air bladder groove 215 is connected to a pressure sensor through a micro air pump to monitor the gap in real time and automatically replenish the air. The deformation of the hatch opening of the hatch flange 111 causes a gap in the main seal, which improves the overall sealing performance of the device.

[0027] When using the sealing structure of this ship hatch cover, the connection between the ship hatch cover and the hull flange 111 is no longer achieved using bolts. During installation, pull the limiting rod 313 to move it away from the mounting base 311, and place the ship hatch cover body 211 downwards so that the mounting base 311 engages with the hull flange 111. At this time, the spring 315 is in a compressed and stored state. Release the limiting rod 313, and use the elastic force of the spring 315 to drive the limiting rod 313 into the slot inside the mounting base 311. The pushing force of the spring 315 can make the mounting base 311 and the ship hatch cover body 211 securely above the hull flange 111, eliminating the need for multiple sets of bolts for limiting installation. The operation is now complete.
