[0002] As a lightweight and high-strength composite material, FRP is widely used in the field of shipbuilding due to its excellent corrosion resistance, good insulation and low cost. FRP submarine doors are made of this material mainly because of its high chemical corrosion resistance, low water absorption and good designability. These characteristics enable FRP submarine doors to maintain long-term performance stability in the marine environment.

[0003] Under long-term use, the installation location of the submarine door still needs long-term maintenance, and the residues of barnacles, tiny shells and water plants should be cleaned. Because the sealing performance of the conventional submarine door structure is poor, it is easy for small impurities to penetrate the interior, and disassembly and cleaning is time-consuming and laborious.

[0004] The present application provides a fiberglass hull seabed door installation structure, which can effectively reduce the collision rate of the seabed door through its own countersunk installation method, and at the same time, the internal connection structure also cooperates with the sealing installation structure of the countersunk installation structure to reduce the entry of impurities and erosion. The two sets of longitudinal and transverse distribution installation structures further improve the stability of the installation structure. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1As shown, a fiberglass hull submarine door installation structure includes an external shell; the external shell 1 is fixed at the submarine door position on the bottom of the ship, and a mounting opening 14 is opened on the bottom plate 3 of the external shell 1 itself, and the mounting opening 14 is clamped at the submarine door joint position on the bottom of the ship; wherein, the external shell 1 is a set plate that matches the submarine door installation structure position, and can be used as a layer of protective plate structure. The mounting opening 14 opened at the bottom plate 3 of the external shell 1 is an open hole structure that matches the installation positioning.

[0023] The external shell 1 is docked with a carrier plate 6 along the open position of the bottom plate 3, and a long strip mounting seat 4 is installed in the middle section of the carrier plate 6. The long strip mounting seat 4 is docked through a manual bolt 7. The carrier plate 6 retains a countersunk mounting mechanism on both sides of the long strip mounting seat 4, and an auxiliary docking joint 11 is docked in the countersunk mounting mechanism. The auxiliary docking joint 11 extends into the mounting port 14 along the countersunk mounting mechanism, and the auxiliary docking joint 11 extending into the mounting port 14 is docked with the joint of the sea bottom door of the ship. Among them, the external shell 1 is docked with the carrier plate 6 through the long strip mounting seat 4, and the carrier plate 6 belongs to the overall loading structure for further fixing and protecting the installation structure of the sea bottom door. The auxiliary docking joint 11 that is subsequently docked with the carrier plate 6 is the main component of the sealing installation. The auxiliary docking joint 11 cooperates with the countersunk mounting mechanism on the carrier plate 6 to effectively reduce the contact surface with the air and seawater, ensuring that the sea bottom door has sufficient corrosion resistance at the installation position.

[0024] like Figure 1 As shown, the long strip mounting seat 4 is movably extended into the carrier plate 6 along the position of the ear piece 8, and the inner end surface of the long strip mounting seat 4 extended into the carrier plate 6 is squeezed and contacted with the plane around the bolt hole 2; the long strip mounting seat 4 is manually countersunk along the position of the ear piece 8, and this structure is responsible for docking the carrier plate 6 with the external shell 1.

[0025] The bolt hole 2 is provided in the middle section of the external housing 1;

[0026] The ear piece 8 is an integral extension structure of the carrier plate 6 .

[0027] like Figure 1 As shown, the upper and lower ends of the strip mounting seat 4 are horizontally inserted with manual bolts 7, the rear end of the manual bolt 7 is butted with the bolt hole 2, and the front end of the manual bolt 7 is filled with an anti-rust layer along the plane of the strip mounting seat 4. The manual bolt 7 is manually operated to complete the butt mounting process, and in order to prevent the manual bolt 7 from rusting, an anti-rust layer is filled on the front end surface.

[0028] like Figure 1 As shown, the countersunk head installation mechanism includes a countersunk head shaft section 10, a sleeve 9 and a guide shaft 5;

[0029] The countersunk shaft section 10 is fixedly installed in the shaft hole opened in the carrier plate 6. The countersunk shaft section 10 is a hollow structure. The inner ring of the countersunk shaft section 10 is in clearance with the outer wall of the sleeve 9. The sleeve 9 is provided with an auxiliary butt joint 11. The bottom end of the auxiliary butt joint 11 is connected to the guide shaft 5 built into the sleeve 9 for transmission connection. The bottom end of the guide shaft 5 is connected to the bottom sea door joint of the ship. Among them, the countersunk shaft section 10 uses its own sleeve 9 installation structure to install the auxiliary butt joint 11 together. Since the outer side is protected by the sleeve 9, the auxiliary butt joint 11 itself can be effectively protected from corrosion.

[0030] like Figure 1 As shown, an operating end 12 is installed on the top of the auxiliary docking head 11; the operating end 12 can cooperate with manual operation to complete the feeding action.

[0031] A sealing ring 13 is installed in the middle section of the auxiliary joint 11. The sealing ring 13 can provide an additional protection to ensure that no water or impurities enter the interior.

[0032] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
