Description

Technical Field

[0001] The present application relates to the technical field of refrigerated truck sealing, and in particular to a ship rectangular air duct cabin structure. Background Art

[0002] A through-cabin structure refers to a mechanical device that runs through the cabin of a ship and is used to support and fix marine equipment, such as generators, pumps, pipes, etc. The through-cabin structure is usually welded from steel plates. Its shape and size are designed according to actual needs. It can adapt to different equipment and ship types, enhance the structural strength of the ship, and improve the safety and stability of the ship. At the same time, the through-cabin structure can also facilitate the installation and maintenance of equipment and reduce the impact on the hull structure and performance.

[0003] Patent No. 202123207965.2 discloses a rectangular air duct through-cabin structure for ships, including a first through-cabin component, a second through-cabin component, an angle steel flange, a rectangular air duct, a fireproof partition and an opening. The first through-cabin component and the second through-cabin component are respectively connected to the side walls on both sides of the opening on the bulkhead or deck, which can reduce the structural opening, especially the larger rectangular air duct. If this through-cabin type with both sides welded to the structure is adopted, it can not only effectively reduce the structural opening, but also reduce the modification of related structures. The through-cabin structure can reduce the use of webs. On the one hand, the design of webs can be reduced in the design stage, and the design modeling and drawing work can be reduced. At the same time, the coordination work with structural professionals can be reduced, which is very helpful to improve the design efficiency. Only two short-circuited air ducts with flanges need to be made, which reduces the production of webs compared with conventional through-cabin components. In addition, this through-cabin component only needs to burn a fillet weld with the deck on one side, which reduces the welding work and is very helpful to improve the construction efficiency.

[0004] However, in use, there are the following defects:

[0005] Although the first through-cabin component and the second through-cabin component are used to connect the two sides of the deck opening, since they are installed separately on both sides of the opening and then fixed with flange components, the through-cabin components on both sides may not be on the same horizontal line during installation, affecting the overall stability of the structure. Utility Model Content

[0006] The purpose of the present application is to provide a rectangular air duct through-cabin structure for ships, which solves the problem proposed in the background technology that although a first through-cabin component and a second through-cabin component are used to connect the two sides of the deck opening, since they are installed separately on both sides of the opening and then fixed with flange components, the through-cabin components on both sides may not be on the same horizontal line during installation, affecting the overall stability of the structure.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a ship rectangular air duct through-cabin structure, comprising a hull cabin plate, a fixing plate, fixing rivets, fixing bolts, a connecting rod and a center hole, a circular hole is opened in the center of the surface of the fixing plate, a through-cabin part is fixedly welded to the surface of the fixing plate outside the circular hole, a cross bar is fixedly welded to the inner wall of the through-cabin part, a center hole is opened in the center of the top end of the cross bar, an inner limit ring is fixedly connected to the top end of the cross bar outside the center hole, and an outer limit ring is fixedly connected to the bottom of the cross bar outside the center hole, bolt holes are opened on the side walls of the outer limit ring and the inner limit ring, the fixing bolts pass through the bolt holes and are detachably connected to the upper limit ring and the lower limit ring, and the two ends of the connecting rod pass through the centerline hole, the upper limit ring and the lower limit ring.

[0008] In this technical solution, fixing plates are respectively fitted at both ends of the hull bulkhead, and then both ends of the connecting rod are passed through the center hole in the center of the crossbar and the inner limit ring and the outer limit ring. The through-cabin parts on both sides can be kept level through the inner limit ring, the outer limit ring, the bolt holes, the fixing bolts and the connecting rod. The fixing plates on both sides are fitted to the hull bulkhead according to the thickness of the hull bulkhead, and then the fixing bolts are inserted into the bolt holes and tightened to fix the connecting rod and prevent it from sliding. Therefore, during the installation process, the through-cabin parts on both sides can always be kept on the same horizontal line under the connection of the connecting rod, and the connection The rod can slide freely to adjust the spacing according to the thickness of the hull cabin plate, thereby improving the convenience of installation and improving the overall stability. At the same time, the stability and structural strength of the device can be further improved through the fixing plate, fixing port, fixing rivet and sealing gasket. The fixing rivet passes through the fixing port and is connected to the hull cabin plate, and the sealing gasket can seal the gap between the fixing plate and the cabin plate, which not only ensures the flatness and stability of the installation, but also prevents air leakage and increases the ventilation efficiency. After the cabin through-cabin parts are installed, the rectangular air duct can be connected to the rectangular air duct through a rubber ring.

[0009] As an optional solution of the technical solution of the present application, ventilation holes are provided at the top ends of the cross bars on both sides of the central hole.

[0010] As an optional solution of the technical solution of the present application, a sealing gasket is movably connected to the surface of the fixed plate outside the circular hole.

[0011] As an optional solution of the technical solution of the present application, fixing openings are opened on both sides of the surface of the fixing plate outside the sealing gasket, and the fixing rivets pass through the fixing openings and are detachably connected to the fixing plate and the hull cabin plate.

[0012] As an optional solution of the technical solution of the present application, the inner side wall of the through-chamber component at one end away from the fixed plate is detachably connected with a rubber ring, and one end of the rectangular air duct is detachably connected to the through-chamber component through the rubber ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present application can keep the through-cabin parts on both sides level through the inner limit ring, the outer limit ring, the bolt holes, the fixing bolts and the connecting rod, and then insert the fixing bolts into the bolt holes and tighten them to fix the connecting rod and prevent it from sliding. Therefore, during the installation process, the through-cabin parts on both sides can always be kept on the same horizontal line under the connection of the connecting rod, and the connecting rod can freely slide to adjust the spacing according to the thickness of the hull cabin plate, thereby improving the convenience of installation and improving the overall stability.

[0015] 2. The present application can further improve the stability and structural strength of the device through the fixing plate, fixing port, fixing rivet and sealing gasket. The fixing rivet passes through the fixing port and is connected to the hull cabin plate, and the sealing gasket can seal the gap between the fixing plate and the cabin plate, which not only ensures the flatness and stability of the installation, but also prevents air leakage and increases the ventilation efficiency.
