Abstract
Description
Technical Field
[0001] This invention relates to the field of marine engineering technology, and in particular to a fragment protection and buffer device for ship recovery compartments. Background Technology
[0002] During ship recovery operations, the compartments may come into contact with hard objects such as cargo debris, metal fragments, and fallen tools. These objects are prone to impact or collision under ship turbulence and handling conditions. At the same time, the complex marine navigation environment means that the displacement of equipment and the swaying of cargo caused by wind and waves can also cause impacts on the interior walls and surfaces of critical equipment, which may lead to structural damage to the compartments, equipment failure, or even threaten personnel safety due to flying fragments.
[0003] Traditional compartment protection often uses a single steel plate or simple cushioning material, lacking a multi-layered, coordinated energy-absorbing structure. The instantaneous impact force generated by a collision can be directly transmitted to the main structure of the compartment or internal precision equipment, leading to decreased equipment accuracy and structural fatigue damage. Long-term accumulation may affect the safety of ship navigation. The high-frequency noise and vibration generated during the collision impact not only affect the working comfort of personnel inside the compartment but may also interfere with the normal operation of precision instruments and reduce work efficiency. Traditional protective devices also lack an effective collision warning mechanism. After a collision, the damage is often hidden inside, making it difficult for staff to detect through visual observation. Disassembly and inspection are required to confirm the protective status, which not only increases the maintenance workload but may also lead to protective failure due to the failure to detect hidden damage in time, causing secondary safety risks. Summary of the Invention
[0004] This invention relates to a fragment protection and buffer device for ship recovery compartments. High-strength protective steel plates at the top and middle directly resist fragment impacts and collisions with foreign objects. The viscoelastic deformation of the rubber buffer block and the compression and rebound of the uniformly distributed internal spring buffer components work together to convert instantaneous impact force into elastic potential energy and heat energy, which are gradually released. A honeycomb-shaped wooden support block at the bottom and a sponge base plate provide secondary buffering to absorb residual impact force. Simultaneously, a red warning solution inside a glass tube breaks and flows out when the device is subjected to an effective impact. This solution diffuses through a liquid guide channel in the middle protective steel plate to a non-woven fabric pad, and the dyeing effect can be visually observed through the top opening. Workers can quickly inspect and assess the impact situation using a transparent silicone sheet. This effectively protects the compartment structure and equipment, while also promptly detecting hidden damage to prevent protection failure and reduce maintenance costs.
[0005] This invention provides a fragment protection and buffer device for ship recovery compartments, specifically comprising: a rubber buffer block, wherein a buffer cavity is formed inside the rubber buffer block, and spring buffer members are uniformly distributed inside the buffer cavity. In their natural state, the top and bottom ends of the spring buffer members are in contact with the top and bottom surfaces of the inner end of the buffer cavity, respectively; a central protective steel plate is fixedly installed on the top surface of the rubber buffer block, and a top protective steel plate is provided above the central protective steel plate; between the central protective steel plate and the top protective steel plate, two symmetrically distributed non-woven fabric pads are bonded to their opposite end faces. A gap area is reserved between the two non-woven fabric pads; five glass tubes are inserted between the middle protective steel plate and the top protective steel plate, corresponding to the gap area between the two non-woven fabric pads; the outer circumferential surface of the glass tubes is in contact with the bottom end surface of the top protective steel plate and the top end surface of the middle protective steel plate, and the glass tubes on both sides are in contact with the adjacent non-woven fabric pads respectively.
[0006] Furthermore, the glass tube has an internal hollow structure, and the cavity is filled with a warning solution that is red.
[0007] Furthermore, the top protective steel plate has two symmetrical observation openings that penetrate its bottom surface, and the two observation openings correspond to the positions of the two non-woven fabric pads respectively; a transparent silicone sheet is adhered to the top surface of the top protective steel plate.
[0008] Furthermore, five liquid guiding grooves are evenly distributed in the middle area of the top surface of the central protective steel plate, and the liquid guiding grooves correspond to the positions of the glass tubes; the length of the liquid guiding grooves is greater than the distance between the two observation openings.
[0009] Furthermore, a bottom protective steel plate is fixedly installed on the bottom end face of the rubber buffer block, and a wooden bearing block is fixedly installed on the bottom end face of the bottom protective steel plate. The wooden bearing block has a honeycomb structure.
[0010] Furthermore, the bottom end face of the rubber buffer block is provided with a ventilation micro-hole that communicates with the buffer cavity at the complete honeycomb opening of the wooden support block; the top end face of the bottom protective steel plate is provided with a mating hole that penetrates the bottom end face of the bottom protective steel plate at each ventilation micro-hole.
[0011] Furthermore, a noise-reducing cotton ball is placed inside each complete honeycomb opening of the wooden support block; a sponge base plate is fixedly installed on the bottom surface of the wooden support block.
[0012] Furthermore, it also includes an outer shell, the outer shell having a protective cavity extending through its bottom end face, and a protective opening communicating with the protective cavity on the top end face of the outer shell; a countersunk through hole extending through its bottom end face is provided at each of the four corners adjacent to the edges of the top end face of the outer shell; the silicone transparent sheet, top protective steel plate, non-woven fabric pad, glass tube, middle protective steel plate, rubber buffer block, bottom protective steel plate, wooden load-bearing block, sponge base plate and noise-reducing cotton balls are all installed inside the protective cavity.
[0013] This invention provides a fragment protection and buffer device for ship recovery compartments, which has the following beneficial effects: The top and middle protective steel plates of this invention directly resist fragment impacts and foreign object collisions due to their high strength. The viscoelastic deformation of the rubber buffer block and the compression and rebound of the uniformly distributed spring buffer inside work together to convert the instantaneous impact force into elastic potential energy and heat energy for gradual release, prolonging the impact time and significantly reducing the impact peak. The honeycomb-shaped wooden support block at the bottom and the sponge bottom plate form a secondary buffer to further absorb residual impact force and prevent impact energy from being transferred to the cabin structure or equipment, effectively protecting the integrity of the cabin and the operational stability of the equipment.
[0014] When the device is subjected to a valid impact, the red warning solution filled inside the glass tube of this invention will break and flow out with the glass tube. It will then quickly diffuse through the liquid guide channel of the central protective steel plate to the non-woven fabric pad, staining the non-woven fabric pad. The length of the liquid guide channel covers the observation opening range, ensuring that the staining effect can be directly observed through the observation opening of the top protective steel plate. It is possible to determine whether a collision has occurred without disassembling the device. Moreover, staff can quickly inspect the device through the transparent silicone sheet without the need for professional testing equipment. Timely detection of collision damage can prevent the device from failing due to hidden damage, reduce subsequent maintenance or replacement costs, and ensure the continuity of protection.
[0015] The buffer cavity of the rubber buffer block of the present invention forms a smooth exhaust channel through the ventilated micropores, the matching holes of the bottom protective steel plate and the honeycomb opening of the wooden support block. When the buffer cavity is compressed and contracted, the internal air can be quickly discharged, avoiding the formation of air pressure resistance that affects the deformation and energy absorption effect of the rubber and spring, ensuring that the buffer structure always maintains a highly efficient energy absorption state, and improving the stability and reliability of impact protection.
[0016] The noise-reducing cotton balls inside the honeycomb opening of the wooden support block of this invention absorb high-frequency noise generated by collisions through the air vibration damping effect of the porous structure. The sponge base plate has both buffering and sound absorption functions, further weakening low-frequency vibrations and residual noise, achieving the simultaneous effect of energy absorption and noise reduction. The flexible materials of the rubber buffer block and the sponge base plate work together with the honeycomb structure of the wooden support block to effectively block the transmission of impact vibration to the cabin structure, avoid the impact of vibration on the operating accuracy of the equipment in the cabin and the comfort of the personnel, and improve the working environment of the cabin.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example: Please refer to Figures 1 to 12 : This invention proposes a fragment protection and buffer device for ship recovery compartments, comprising: a rubber buffer block 7, with a buffer cavity 702 inside the rubber buffer block 7, and spring buffer elements 703 uniformly distributed inside the buffer cavity 702. In its natural state, the top and bottom ends of the spring buffer elements 703 are in contact with the top and bottom surfaces of the inner end of the buffer cavity 702, respectively. Upon impact, the rubber buffer block 7 absorbs energy initially. Subsequently, the spring buffer elements 703 uniformly distributed inside the buffer cavity 702 of the rubber buffer block 7 undergo compression deformation, further storing and releasing elastic potential energy, forming a synergistic buffering system of rubber and springs, effectively prolonging the impact time and reducing the impact of instantaneous impact force on the compartment; a central protective steel plate 6 is fixedly installed on the top surface of the rubber buffer block 7, and a top protective steel plate 3 is provided above the central protective steel plate 6. Between the central protective steel plate 6 and the top protective steel plate 3, two symmetrically distributed non-woven fabric pads 4 are bonded to their opposite end faces. A gap area is reserved between the two non-woven fabric pads 4; five glass tubes 5 are inserted between the middle protective steel plate 6 and the top protective steel plate 3, corresponding to the gap area between the two non-woven fabric pads 4; the outer circumference of the glass tubes 5 is in contact with the bottom end of the top protective steel plate 3 and the top end of the middle protective steel plate 6, and the glass tubes 5 on both sides are in contact with the adjacent non-woven fabric pads 4 respectively; the glass tubes 5 have an inner hollow structure, and the cavity is filled with a warning solution 501 that is red; the top end of the top protective steel plate 3 has two observation openings 301 that penetrate its bottom end, and the two observation openings 301 correspond to the positions of the two non-woven fabric pads 4 respectively; a silicone transparent sheet 2 is bonded to the top end of the top protective steel plate 3; five liquid guiding grooves 601 are evenly distributed in the middle area of the top end of the middle protective steel plate 6, and the liquid guiding grooves 601 correspond to the positions of the glass tubes 5; the length of the liquid guiding grooves 601 is greater than the distance between the two observation openings 301.
[0022] The rubber buffer block 7 has a bottom protective steel plate 8 fixedly installed on its bottom end face, and a wooden support block 9 is fixedly installed on the bottom end face of the bottom protective steel plate 8. The wooden support block 9 has a honeycomb structure. A ventilated micro-hole 701 communicating with the buffer cavity 702 is provided on the bottom end face of the rubber buffer block 7 corresponding to the complete honeycomb opening of the wooden support block 9. A mating hole 801 penetrating the bottom end face of the bottom protective steel plate 8 is provided on the top end face of the bottom protective steel plate 8 corresponding to each ventilated micro-hole 701. A [missing information - likely a type of material] is placed inside each complete honeycomb opening of the wooden support block 9. A noise-reducing cotton ball 11 is placed inside the honeycomb opening. The vibration and noise generated during the collision are transmitted to the wooden support block 9 and are first absorbed by the noise-reducing cotton ball 11. Because the noise-reducing cotton ball 11 has a porous structure, it can convert the sound wave energy into heat energy and dissipate it through the damping effect of air vibration in the pores. A sponge base plate 10 is fixedly installed on the bottom surface of the wooden support block 9. The sponge base plate 10 can cooperate with the noise-reducing cotton ball 11 to reduce noise. The flexible material of the sponge can effectively weaken the vibration transmission, and its porous structure can also help absorb some residual noise.
[0023] The system also includes an outer shell 1, with a protective cavity 103 extending through its bottom surface inside the outer shell 1, and a protective opening 101 connecting the protective cavity 103 on the top surface of the outer shell 1; countersunk through holes 102 extending through its bottom surface are provided at the four corners adjacent to the edges of the top surface of the outer shell 1; a silicone transparent sheet 2, a top protective steel plate 3, a non-woven fabric pad 4, a glass tube 5, a middle protective steel plate 6, a rubber buffer block 7, a bottom protective steel plate 8, a wooden load-bearing block 9, a sponge base plate 10, and noise-reducing cotton balls 11 are all installed inside the protective cavity 103.
[0024] The working principle of this embodiment: According to the areas that need protection in the ship's recovery compartment (such as the inner walls of the compartment and the parts around the equipment that are prone to collision), clean the oil, rust and debris from the installation surface to ensure that the installation surface is flat and dry. Attach the assembled device to the installation position and position it through the countersunk through holes 102 at the four edges of the top surface of the outer shell 1. Use a suitable drilling tool to drill holes at the corresponding positions on the installation surface of the compartment. Install expansion bolt sleeves or threaded seats according to the material of the compartment (such as steel or composite materials). Pass the bolts through the countersunk through holes 102 of the outer shell 1 and tighten them with the expansion sleeves or threaded seats on the installation surface. The bolt heads are embedded in the countersunk through holes 102 to ensure that the entire device fits tightly to the installation surface without any loose gaps. When an external object collides with the device, the impact force first acts on the silicone transparent sheet 2 and the top protective steel plate 3. This impact force is quickly transmitted to the gap area between the top protective steel plate 3 and the middle protective steel plate 6, causing the two steel plates to move closer to each other along the direction of force, and jointly squeeze the five glass tubes 5 located between them. At this time, the glass tubes 5 are effectively impacted (not just slightly rubbed), and thus break. After the glass tubes 5 break, the red warning solution 501 filled inside flows out quickly. Since the liquid guide groove 601 opened on the top surface of the middle protective steel plate 6 corresponds to the position of the glass tubes 5, the warning solution 501 can flow along the liquid guide groove 601, accelerating the diffusion of the warning solution 501. At the same time, the length of the groove covers the range of the two observation openings 301, ensuring that the solution evenly covers the non-woven fabric pad 4. The two non-woven fabric pads 4 adjacent to the glass tube 5 can quickly absorb the warning solution 501 and maintain its dyed state due to the characteristics of their material. They are not easy to fade. During routine maintenance, the staff does not need to disassemble the device. They can simply look through the silicone transparent sheet 2 at the top of the top protective steel plate 3 and the two observation openings 301 on the top protective steel plate 3 (which correspond precisely to the positions of the non-woven fabric pads 4) to directly observe whether the non-woven fabric pads 4 are dyed. This allows for a quick determination of whether the device has been hit by an external object, preventing internal damage from going undetected and causing the protection to fail. The impact force generated by the collision of foreign objects is transmitted to the rubber buffer block 7 through the top protective steel plate 3 and the middle protective steel plate 6. The initial energy absorption is achieved through the viscoelastic properties of the rubber material. Under the action of external force, the rubber molecular chain network can produce a large proportion of elastic deformation. At the same time, the friction between the molecular chains converts some mechanical energy into heat energy and dissipates it. Subsequently, the spring buffer 703 evenly distributed in the buffer cavity 702 inside the rubber buffer block 7 undergoes compression deformation, further storing and releasing elastic potential energy, forming a synergistic buffer system of rubber and spring, which effectively prolongs the impact time and reduces the impact of instantaneous impact force on the cabin. When the buffer cavity 702 of the rubber buffer block 7 is compressed, its volume will shrink rapidly. If the air in the cavity cannot be discharged in time, it will form air pressure resistance and greatly reduce the buffering efficiency. To this end, the device is designed with a multi-path exhaust channel: the air in the buffer cavity 702 first flows out through the ventilated micropores 701 at the bottom of the rubber buffer block 7, enters the honeycomb opening of the wooden support block 9 through the corresponding mating holes 801 on the bottom protective steel plate 8, and finally is discharged through the porous gaps of the sponge bottom plate 10. The entire exhaust process is unobstructed, ensuring that the buffer structure can deform smoothly and give full play to the energy absorption effect. The wooden support block 9 below the bottom protective steel plate 8 adopts a biomimetic honeycomb structure. This structure combines lightweight and high strength. Its hexagonal units can distribute the load through overall force distribution. While supporting the weight of all the protective components above, its own deformation is minimal, providing a solid and stable foundation for the device. Each intact honeycomb opening of the wooden support block 9 contains a noise-reducing cotton ball 11. When the vibrations and noise generated by the collision are transmitted to the wooden support block 9, they are first absorbed by the noise-reducing cotton ball 11 placed in each intact honeycomb opening. The noise-reducing cotton ball 11 has a porous structure, which can convert sound wave energy into heat energy and dissipate it through the damping effect of air vibration in the pores. Subsequently, the remaining low-frequency vibrations are further buffered and absorbed by the sponge base plate 10. The flexible material of the sponge can effectively weaken the transmission of vibration, and its porous structure can also help absorb some residual noise, ultimately achieving a dual noise reduction effect and reducing the interference of collision noise on the cabin environment.
