Description

Technical Field

[0001] This invention relates to the field of fiberglass bulkhead penetration technology, specifically to an adjustable positioning mounting base for a fiberglass bulkhead penetration. Background Technology

[0002] In the field of shipbuilding and marine engineering, fiberglass composite materials are widely used in bulkhead manufacturing due to their advantages such as lightweight, high strength, and corrosion resistance. The sealing and securing of pipes, cables, and other penetrations through the bulkhead are crucial for ensuring the ship's watertightness and fire safety. Traditional fiberglass bulkhead penetration installation structures typically employ an inner and outer flange system with bolts for fastening. This involves tightening multiple bolts one by one to clamp the inner and outer flanges to both sides of the bulkhead, and using rubber gaskets at the contact surfaces to achieve a seal.

[0003] The installation of traditional fiberglass bulkhead penetrations requires manual tightening of bolts one by one, which makes it difficult to ensure a uniform distribution of clamping force in the circumferential direction. This can easily lead to flange tilting or localized stress concentration. Furthermore, the low interlaminar shear strength of fiberglass materials means that uneven loads can easily cause delamination, cracking, or even structural damage around the bulkhead openings. Secondly, traditional structures lack effective coaxiality self-correction capabilities. If the inner and outer flanges are not aligned during installation, forced tightening can damage the gaskets or cause the penetration to be installed at an angle, affecting the connection accuracy of subsequent pipelines. Thirdly, for the positioning and sealing of the penetration itself, existing technologies mostly use stuffing boxes or fixed sealing rings. Once installed, these are difficult to fine-tune. If the axial position or angle of the penetration needs to be adjusted, the lock nut often needs to be loosened. At this time, the seal fails and the operating resistance is high, making it impossible to achieve damage-free adjustment while maintaining a certain limit.

[0004] To address these technical deficiencies, we propose an adjustable positioning mount for fiberglass bulkhead penetration components. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an adjustable positioning mounting base for fiberglass bulkhead penetration components. By employing a servo motor-driven gear ring linkage mechanism, a single power source is synchronously transmitted to all locking screws, achieving absolute synchronous rotation and feeding of multi-point bolts and ensuring uniform distribution of clamping force in the circumferential direction. This effectively avoids crushing or delamination damage to the fiberglass substrate caused by localized stress concentration. Combined with real-time feedback from a pressure sensor, the compression of the sealing gasket can be precisely controlled, ensuring long-term watertight reliability while maximizing the protection of the fiberglass bulkhead structure and significantly improving the installation efficiency of fiberglass bulkhead penetration components.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable positioning mounting base for a fiberglass bulkhead penetration component, comprising an outer mounting ring disposed on the outer side of the fiberglass bulkhead and an inner mounting ring disposed on the inner side of the fiberglass bulkhead, a through hole provided inside the fiberglass bulkhead and between the outer and inner mounting rings, a positioning connection portion provided between the outer and inner mounting rings for quick positioning during installation; and a locking mounting portion provided between the outer and inner mounting rings for use in connecting the outer and inner mounting rings. The locking and positioning are performed between them, and the installation pressure is monitored in real time. One side of both the outer and inner mounting rings is integrally formed with a positioning frame, and the interior of both positioning frames is equipped with an adjustable sealing part. After the outer and inner mounting rings are installed on the inside and outside of the through hole, the through piece is installed through the interior of the outer and inner mounting rings. The adjustable sealing parts inside the two positioning frames seal and position both sides of the surface of the through piece. When adjusting the through piece, the adjustable sealing parts release the sealing and positioning of the through piece, while providing rolling limit for the surface of the through piece.

[0007] Furthermore, the positioning connection part includes a positioning arc plate one and a positioning arc plate two. Several positioning arc plates one are fixedly provided on one side of the outer mounting ring, and several positioning arc plates two are fixedly provided on one side of the inner mounting ring. The several positioning arc plates one and positioning arc plates two are all distributed at equal angles about the central axis of the outer mounting ring. One side of the several positioning arc plates one is slidably connected to the interior of the several positioning arc plates two. One side of the several positioning arc plates one and the several positioning arc plates two are all fixedly provided with mounting positioning blocks, and the outer surface of the several mounting positioning blocks is in slidable contact with the interior of the through hole.

[0008] Furthermore, a first mounting sealing ring is fixedly provided on one side of the outer mounting ring, and a sealing mating ring is fixedly provided on one side of the first mounting sealing ring; a second mounting sealing ring is fixedly provided on one side of the inner mounting ring, and a mating groove is provided on one side of the second mounting sealing ring; one side of the sealing mating ring and one side of the mating groove are slidably connected.

[0009] Furthermore, the locking mounting part includes locking screws, and a plurality of locking screws are rotatably provided on the side of the outer mounting ring facing the inner mounting ring. A rotating gear ring is also rotatably provided on one side inside the outer mounting ring. One end of each of the plurality of locking screws is fixedly provided with a driven gear, and the tooth surfaces of the plurality of driven gears mesh with the inner tooth surface of the rotating gear ring for transmission.

[0010] Furthermore, a mounting servo motor is fixedly installed on one side inside the outer mounting ring, and a drive gear is fixedly installed at one end of the output shaft of the mounting servo motor. The tooth surface of the drive gear meshes with the outer tooth surface of the rotating gear ring for transmission. The inner mounting ring is also provided with a number of mounting threaded holes on the side facing the outer mounting ring, and one end of a number of locking screws is respectively connected to the internal threads of the number of mounting threaded holes.

[0011] Furthermore, the adjustable sealing part includes a combined sealing frame, with each of the two positioning frames having a movable groove inside, and four combined sealing frames being movably arranged inside the movable groove; four sealing servo electric cylinders are fixedly arranged on the outer circumferential surface of the positioning frame, and the drive ends of the four sealing servo electric cylinders are respectively fixedly connected to one side of the four combined sealing frames; one side of each of the four combined sealing frames has a pressing sealing groove, and a sealing gasket is arranged inside each of the four pressing sealing grooves.

[0012] Furthermore, both sides of the combined sealing frame are fixedly provided with fixing blocks, and both sides of the fixing blocks are slidably provided with sliding rods. One end of each sliding rod is fixedly provided with a support block, and one side of the support block is rotatably provided with several adjusting balls. Both sides of the fixing blocks are fixedly provided with fixing rods, and the top ends of the two fixing rods are slidably connected to the interior of the two sliding rods respectively. The surfaces of the two fixing rods are also fitted with springs, and the top ends of the springs are fixedly connected to the bottom of the sliding rods.

[0013] Furthermore, both the outer and inner mounting rings have planar sealing grooves on opposite sides for sealing and fitting the planar fiberglass bulkhead. One side of each planar sealing groove extends to the inner and outer sides of the fiberglass bulkhead. Assembly blocks are also threaded onto the outer circumferential surfaces of the outer and inner mounting rings. Each assembly block has an arc-shaped fitting block fixedly mounted on the side facing the fiberglass bulkhead. Arc-shaped sealing grooves are provided on opposite sides of each arc-shaped fitting block, and one side of each arc-shaped sealing groove extends to the inner and outer sides of the fiberglass bulkhead. These are used for sealing and fitting the arc-shaped fiberglass bulkhead.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] 1. Utilizing a sliding guide connection formed by equidistantly distributed locating arc-shaped plates and installation locating blocks, the radial displacement and circumferential rotation errors can be automatically corrected during the insertion of inner and outer installation rings. This transforms the complex alignment process into a simple mechanical insertion action, ensuring that the sealing ring is accurately inserted into the mating groove, thus eliminating the risk of seal failure caused by human alignment deviations. Simultaneously, a servo motor-driven gear ring linkage mechanism synchronously transmits a single power source to all locking screws, achieving absolute synchronous rotation and feeding of multi-point bolts and ensuring uniform distribution of clamping force in the circumferential direction. This effectively avoids localized stress concentration that could cause crushing or delamination damage to the fiberglass substrate. Combined with real-time feedback from pressure sensors, the compression of the sealing gasket can be precisely controlled, ensuring long-term watertight reliability while protecting the fiberglass bulkhead structure and significantly improving the installation efficiency of fiberglass bulkhead penetration components.

[0016] 2. During the adjustment phase, the adjusting balls on the support block form rolling friction contact with the surface of the through-piece. Combined with the elastic support of the spring, this minimizes the resistance during axial sliding and angle fine-tuning of the through-piece, and prevents scratching of the anti-corrosion coating or plating on the surface of the through-piece. This achieves high-precision, non-destructive alignment. During the locking phase, the split-type combined sealing frame is radially closed by a servo electric cylinder, instantly converting sliding friction into high-pressure static friction. This forces the sealing gasket in the sealing groove to undergo elastic deformation and tightly adhere to the outer wall of the through-piece, forming a reliable fluid barrier layer. This not only allows for adjustments to the position of the through-piece during the later stages of installation but also accommodates through-pieces of different diameters. Its split-type assembly structure can adapt to the slight ellipticity or non-roundness of the through-piece, ensuring the continuity and integrity of the sealing interface and greatly enhancing the versatility of the device under complex working conditions.

[0017] 3. At the bulkhead interface, the deep-inserted sealing ring and the mating groove structure form a labyrinthine sealing path. When the hull deformation causes slight relative displacement of the inner and outer mounting rings, the deformation allowance of the elastic gasket can immediately compensate for the gap change, maintain the effective length of the sealing path, and prevent leakage caused by structural deformation. At the through-part interface, the closed cavity formed by the outer side of the combined sealing frame and the inside of the positioning frame constitutes a second line of defense, effectively blocking the intrusion of external media. In addition, the modular design of the planar sealing groove and the detachable arc-shaped fitting block allows the device to flexibly adapt to fiberglass bulkheads with different curvatures, such as flat or curved surfaces, thus improving the applicability of the mounting base.

Therefore, they should not be construed as limitations on this invention.

[0031] Example 1

[0032] Please see Figures 1 to 9 As shown, an adjustable positioning mounting base for a fiberglass bulkhead through-hole includes: an outer mounting ring 1 located on the outer side of the fiberglass bulkhead and an inner mounting ring 2 located on the inner side of the fiberglass bulkhead; a through hole 4 is provided inside the fiberglass bulkhead between the outer mounting ring 1 and the inner mounting ring 2; a positioning connection part is provided between the outer mounting ring 1 and the inner mounting ring 2 for quick positioning during installation, improving the installation efficiency between the outer mounting ring 1 and the inner mounting ring 2; a locking mounting part is also provided between the outer mounting ring 1 and the inner mounting ring 2 for locking and positioning between the outer mounting ring 1 and the inner mounting ring 2, and for real-time monitoring of the installation pressure. The installation of the outer mounting ring 1 and the inner mounting ring 2 is tested to ensure the sealing performance of the outer and inner sides of the fiberglass bulkhead. One side of the outer mounting ring 1 and the inner mounting ring 2 is integrally formed with a positioning frame 3, and the interior of the two positioning frames 3 is provided with an adjustable sealing part 8. After the outer mounting ring 1 and the inner mounting ring 2 are installed on the inside and outside of the through hole 4, the through piece is installed by passing through the interior of the outer mounting ring 1 and the inner mounting ring 2. The adjustable sealing parts 8 inside the two positioning frames 3 seal and position both sides of the surface of the through piece. When adjusting the through piece, the adjustable sealing parts 8 release the sealing and positioning of the through piece, and at the same time provide rolling limit for the surface of the through piece, which facilitates the adjustment operation of the through piece.

[0033] Specifically, the positioning connection part includes a positioning arc plate 5 and a positioning arc plate 6. Several positioning arc plates 5 are fixedly provided on one side of the outer mounting ring 1, and several positioning arc plates 6 are fixedly provided on one side of the inner mounting ring 2. The several positioning arc plates 5 and the positioning arc plates 6 are all distributed at equal angles about the central axis of the outer mounting ring 1. One side of the several positioning arc plates 5 is slidably connected to the inside of the several positioning arc plates 6. One side of the several positioning arc plates 5 and the several positioning arc plates 6 are all fixedly provided with mounting positioning blocks 7, and the outer surface of the several mounting positioning blocks 7 is in slidable contact with the inside of the through hole 4.

[0034] Furthermore, a sealing ring 9 is fixedly provided on one side of the outer mounting ring 1, and a sealing mating ring 11 is fixedly provided on one side of the sealing ring 9; a sealing ring 10 is fixedly provided on one side of the inner mounting ring 2, and a mating groove 12 is provided on one side of the sealing ring 10; one side of the sealing ring 11 is slidably connected to one side of the mating groove 12.

[0035] It should be noted that when positioning and connecting the outer mounting ring 1 and the inner mounting ring 2, the mounting sealing ring 9 on one side of the outer mounting ring 1 is inserted into the through hole 4. The mounting positioning block 7 on the outer side of the positioning arc plate 5 slides against the inner wall of the through hole 4, ensuring that the central axis of the mounting sealing ring 9 inside the through hole 4 coincides with the central axis of the through hole 4. At the same time, the mounting sealing ring 10 on one side of the inner mounting ring 2 is inserted into the through hole 4, and the sealing mating ring 11 on one side of the mounting sealing ring 9 is inserted into the mounting mating groove 12 on one side of the mounting sealing ring 10. The surface of the sealing mating ring 11 is also fitted with a sealing gasket, thus completing the positioning and insertion between the outer mounting ring 1 and the inner mounting ring 2. The outer mounting ring 1 and the inner mounting ring 2 are sealed together by the mounting sealing ring 9 and the mounting sealing ring 10, the sealing mating ring 11, and the mounting mating groove 12.

[0036] Further explanation is needed regarding the insertion and engagement of the locating arc-shaped plates 5, which are evenly distributed on the outer mounting ring 1, and the locating arc-shaped plates 6, on the inner mounting ring 2. Simultaneously, the mounting positioning block 7 acts as a guide key, sliding within the through hole 4 to forcibly restrict the radial displacement and circumferential rotation of the two mounting rings. This ensures that the central axes of the mounting sealing ring 9 and the mounting sealing ring 10 automatically coincide, guiding the sealing mating ring 11 to precisely insert into the mounting mating groove 12, compressing the internal sealing gasket to complete the initial sealing. This transforms the complex coaxiality correction process into a simple mechanical insertion action, eliminating the accumulation of errors from manual alignment and significantly shortening the installation preparation time. Furthermore, the multi-point evenly distributed guide structure effectively disperses the lateral force during insertion, preventing micro-cracks from forming at the edges of the fiberglass bulkhead openings due to excessive localized stress, thus providing a perfect geometric reference for subsequent locking operations.

[0037] Specifically, the locking mounting part includes locking screws 17. A plurality of locking screws 17 are rotatably mounted on the side of the outer mounting ring 1 facing the inner mounting ring 2. A rotating gear ring 15 is also rotatably mounted on one side inside the outer mounting ring 1. A driven gear 16 is fixedly mounted at one end of each locking screw 17, and the tooth surfaces of the driven gears 16 mesh with the inner tooth surface of the rotating gear ring 15. A mounting servo motor 13 is also fixedly mounted on one side inside the outer mounting ring 1, and a drive gear 14 is fixedly mounted at one end of the output shaft of the servo motor 13. The tooth surface of the drive gear 14 meshes with the outer tooth surface of the rotating gear ring 15. A plurality of mounting threaded holes 18 are also provided on the side of the inner mounting ring 2 facing the outer mounting ring 1, and one end of each locking screw 17 is threadedly connected to the internal threads of the mounting threaded holes 18.

[0038] It should be noted that after the outer mounting ring 1 and the inner mounting ring 2 are positioned and connected using the positioning arc plate 5 and the positioning arc plate 6, one end of each of the locking screws 17 is connected to the interior of each of the mounting threaded holes 18. At this time, the output shaft of the mounting servo motor 13 controls the drive gear 14 to rotate, and the drive gear 14 drives the rotating gear ring 15 to rotate. The rotating gear ring 15 drives the locking screws 17 to rotate through the internal meshing of the driven gears 16, so that one end of each locking screw 17 is connected to the interior thread of each of the mounting threaded holes 18 on one side of the inner mounting ring 2, thus completing the installation connection of the outer mounting ring 1 and the inner mounting ring 2 on both sides of the through hole 4.

[0039] Further explanation is needed: the servo motor 13 outputs torque to drive the drive gear 14, which in turn drives the rotating gear ring 15 to rotate. The internal and external gear meshing transmits the rotational motion synchronously to all driven gears 16, thereby driving the locking screw 17, fixed at the center of the driven gear 16, to rotate synchronously and screw into the mounting threaded hole 18 of the inner mounting ring 2. This generates a uniform and controllable axial tensile force, pulling and locking the outer mounting ring 1 and the inner mounting ring 2 together. During this process, the integrated pressure monitoring module collects the screw tension data in real time and feeds it back to the control system to adjust the motor output. This solves the problem of flange surface tilting or uneven gasket compression caused by inconsistent tightening sequence and force in traditional multi-bolt fastening. It achieves an absolutely uniform distribution of clamping force in the circumferential direction, avoiding the risk of crushing the fiberglass substrate due to local stress concentration. Simultaneously, intelligent real-time pressure monitoring ensures that the sealing pressure is always maintained within the optimal design range, guaranteeing both long-term watertightness and preventing structural damage caused by overtightening.

[0040] Specifically, the positioning arc-shaped plate 5 on the outer mounting ring 1 and the positioning arc-shaped plate 6 on the inner mounting ring 2 are inserted and engaged. At the same time, the mounting positioning block 7 slides and guides along the inner wall of the through hole 4, forcing the mounting sealing ring 9 and the mounting sealing ring 10 to automatically align coaxially. Then, the sealing mating ring 11 is inserted into the mounting mating groove 12 to complete the initial positioning and basic sealing. Next, the mounting servo motor 13 is started to drive the drive gear 14 to rotate the rotating gear ring 15, which in turn synchronously drives all driven gears 16 and locking screws 17 to rotate, so that the locking screws 17 are screwed into the mounting threaded hole 18 of the inner mounting ring 2 to generate axial rotation. The tension clamps the outer mounting ring 1 and the inner mounting ring 2 tightly onto both sides of the fiberglass bulkhead. During this process, the pressure monitoring function integrated into the locking installation part can provide real-time feedback on the clamping force data to ensure that the sealing gasket is compressed to the optimal state without damaging the fiberglass substrate. This solves the problems of uneven force and low efficiency caused by tightening bolts one by one in the traditional method. Multi-point synchronous locking is achieved through the gear linkage mechanism, which ensures the uniform distribution of sealing pressure in the circumferential direction and effectively avoids the risk of fiberglass bulkhead delamination or cracking caused by local stress concentration. At the same time, the automated locking and pressure monitoring mechanism greatly improves the installation accuracy and watertightness reliability.

[0041] Example 2

[0042] Specifically, the adjustable sealing part 8 includes a combined sealing frame 20. Each of the two positioning frames 3 has a movable groove 19 inside, and four combined sealing frames 20 are movably mounted inside the movable groove 19. Four sealing servo cylinders 21 are fixedly mounted on the outer periphery of the positioning frame 3, and the drive ends of the four sealing servo cylinders 21 are respectively fixedly connected to one side of the four combined sealing frames 20. The four combined sealing frames 20 are controlled to move relative to each other by the drive ends of the four sealing servo cylinders 21. After the four combined sealing frames 20 are combined, they completely cover the outer periphery of the penetrating part. Each side of the four combined sealing frames 20 has a pressing sealing groove 22, and each of the four pressing sealing grooves 22 has a sealing gasket inside. The combined sealing frames 20 are controlled to fit against the outer periphery of the penetrating part by the drive ends of the sealing servo cylinders 21. The combined sealing frames 20 press the sealing gasket inside the pressing sealing groove 22 onto the surface of the penetrating part, while the outer sides of the four combined sealing frames 20 seal the penetrating part and the interior of the positioning frame 3.

[0043] Furthermore, both sides of the combined sealing frame 20 are fixedly provided with fixing blocks 23, and both sides of the fixing blocks 23 are slidably provided with slide rods 26. One end of each slide rod 26 is fixedly provided with a support block 24, and one side of the support block 24 is rotatably provided with several adjusting balls 25. Both sides of the fixing blocks 23 are fixedly provided with fixing rods 27, and the top ends of the two fixing rods 27 are slidably connected to the inside of the two slide rods 26 respectively. The surfaces of the two fixing rods 27 are also fitted with springs 28, and the top ends of the springs 28 are fixedly connected to the bottom of the slide rods 26.

[0044] It should be noted that when sealing the through-piece, the through-piece passes through the interior of the outer mounting ring 1 and the inner mounting ring 2. At this time, the adjusting ball 25 on one side of the four support blocks 24 contacts the outer surface of the through-piece. Then, the drive end of the sealing servo cylinder 21 controls the combined sealing frame 20 to move closer to the surface of the through-piece. One side of the support block 24 compresses the spring 28 on the surface of the fixed rod 27 through the slide rod 26 until the four combined sealing frames 20 are combined and seal the surface of the through-piece.

[0045] Furthermore, both the outer mounting ring 1 and the inner mounting ring 2 have flat sealing grooves 32 on opposite sides for sealing and fitting the planar fiberglass bulkhead. One side of each of the two flat sealing grooves 32 extends to the inner and outer sides of the fiberglass bulkhead. The outer circumferential surfaces of the outer mounting ring 1 and the inner mounting ring 2 are also threaded with assembly blocks 29. Each of the two assembly blocks 29 has an arc-shaped fitting block 30 fixed on the side facing the fiberglass bulkhead. Each of the two arc-shaped fitting blocks 30 has an arc-shaped sealing groove 31 on opposite sides, and one side of each arc-shaped sealing groove 31 extends to the inner and outer sides of the fiberglass bulkhead. This is for sealing and fitting the arc-shaped fiberglass bulkhead.

[0046] It should be noted that both the planar sealing groove 32 and the arc-shaped sealing groove 31 are equipped with sealing rubber rings, and pressure sensors are evenly distributed at angles inside the planar sealing groove 32 and the arc-shaped sealing groove 31 to monitor the installation pressure of the outer mounting ring 1 and the inner mounting ring 2 on the inner and outer sides of the fiberglass bulkhead in real time, so as to ensure the stability of the installation of the outer mounting ring 1 and the inner mounting ring 2 on the fiberglass bulkhead.

[0047] It should be further explained that when the outer mounting ring 1 and the inner mounting ring 2 are locked and pulled close, the sealing mating ring 11 fixed to the end of the mounting sealing ring 19 slides deep into the mounting mating groove 12 of the mounting sealing ring 20, forcing the sealing gasket fitted on the surface of the sealing mating ring 11 to undergo radial or axial elastic deformation, filling the micro gaps between the metal mating surfaces and forming a continuous fluid barrier layer. At the same time, the main body end faces of the mounting sealing ring 19 and the mounting sealing ring 20 fit tightly together to form a second line of defense. When the ship's navigation causes bulkhead deformation or vibration, resulting in a small relative displacement between the mounting rings, the deep-insertion mating structure can maintain the length of the sealing path unchanged, while the deformation margin of the elastic gasket can immediately compensate for the gap change, preventing sealing failure caused by structural deformation. This multi-seal design significantly improves the reliability and durability of the system under complex sea conditions.

[0048] Specifically, when the penetrator passes through the positioning frame 3, it first contacts the rolling limiting surface formed by the adjusting balls 25 on the support block 24. At this time, the spring 28 is in a pre-compression state, allowing the penetrator to slide axially and make fine-tuning of the angle under low frictional resistance to achieve precise alignment. After the position is determined, the sealing servo cylinder 21 pushes the four combined sealing frames 20 to move radially towards the center, compressing the spring 28 and making the sealing gasket in the sealing groove 22 tightly adhere to the outer surface of the penetrator. Finally, the four combined sealing frames 20 are assembled to form a complete annular sealing cavity, which not only blocks the fluid leakage channel but also mechanically clamps and fixes the penetrator. In the adjustment stage, the adjusting balls 25 are used to convert sliding friction into rolling friction, which greatly reduces the operating resistance and protects the coating on the surface of the penetrator. In the locking stage, the precise control of the servo cylinder enables the application of the sealing pressure as needed, ensuring the sealing consistency under different working conditions. Moreover, this split-type combined sealing frame 20 structure can adapt to penetrators of different diameters, significantly improving the versatility and ease of maintenance of the device.

[0049] Example 3

[0050] Specifically, this embodiment discloses an installation method for an adjustable positioning mounting base for a fiberglass bulkhead penetration member, including the following steps:

[0051] Step 1: First, select the appropriate sealing interface according to the actual structural shape of the fiberglass bulkhead. If the bulkhead is a planar structure, directly use the planar sealing groove 32 on the outer mounting ring 1 and the inner mounting ring 2 and install the sealing rubber ring. If the bulkhead is a curved structure, first thread the assembly block 29 to the outer circumference of the mounting ring, and use the arc sealing groove 31 on the arc fitting block 30 and the internal sealing rubber ring to match the curved surface contour. At the same time, confirm that all pressure sensors have been correctly installed in the sealing groove.

[0052] Step 2: Move the outer mounting ring 1 from the outside of the bulkhead close to the through hole 4, so that the mounting sealing ring 9 extends into the hole. At the same time, guide the mounting positioning block 7 on the outside of the positioning arc plate 5 to slide against the inner wall of the through hole 4. Use multi-point guidance to automatically correct the central axis of the outer mounting ring 1 to coincide with the through hole 4, and prevent lateral force from damaging the fiberglass substrate during the insertion process.

[0053] Step 3: Align the inner mounting ring 2 with the outer mounting ring 1 from the inside of the bulkhead, so that the positioning arc plate 2 6 slides into the mating surface of the positioning arc plate 1 5, and push the inner mounting ring 2 until the mounting mating groove 12 on the mounting sealing ring 2 10 is precisely fitted onto the outside of the sealing mating ring 11 of the mounting sealing ring 1 9. At this time, the sealing gasket fitted on the surface of the sealing mating ring 11 is initially compressed to form a basic sealing layer, thus completing the rapid positioning and insertion of the inner and outer mounting rings.

[0054] Step 4: Connect the ends of several locking screws 17 with one end of the mounting threaded hole 18 of the inner mounting ring 2, start the mounting servo motor 13 inside the outer mounting ring 1, drive the output shaft to drive the drive gear 14 to rotate, and then mesh with the rotating gear ring 15 to synchronously drive all driven gears 16 and locking screws 17 to rotate, so that the locking screws 17 are evenly screwed in to generate axial tension, and tighten the outer mounting ring 1 and the inner mounting ring 2 towards the middle to clamp the fiberglass cabin wall;

[0055] Step 5: During the locking process, read the data from the pressure sensor in the planar sealing groove 32 or the arc-shaped sealing groove 31 in real time, and dynamically adjust the output torque of the servo motor 13 by the controller to ensure that the clamping force in the circumferential direction is evenly distributed and the sealing pressure is maintained in the optimal design range, so as to avoid fiberglass delamination or leakage due to local overpressure or underpressure. Stop the motor and complete the fixing of the bulkhead interface after the preset locking force value is reached.

[0056] Step 6: Pass the through piece to be installed through the channel between the two positioning frames 3. At this time, the outer surface of the through piece first contacts the adjusting ball 25 on the support block 24. Under the pre-compression support of the spring 28, a low-friction rolling limiting surface is formed, which allows the operator to easily push the through piece to make axial displacement and angle fine adjustment until the through piece reaches the designed precise position.

[0057] Step 7: After the position calibration is completed, start the four sealing servo cylinders 21, drive their output ends to push the four combined sealing frames 20 to move radially towards the center along the movable groove 19, compress the spring 28 on the fixed rod 27 and make the sealing gasket in the sealing groove 22 tightly adhere to the outer surface of the penetrating part, until the four combined sealing frames 20 are assembled to form a complete annular sealing cavity, thereby achieving the clamping and fixing of the penetrating part and bidirectional sealing.
