Description

Technical Field

[0001] This application relates to the field of marine operation technology, and in particular to a safety protection device. Background Technology

[0002] During maritime operations and navigation, situations frequently arise where two vessels approach each other and need to exchange personnel, such as in maritime rescue, resupply, and personnel reassignment. Due to the complex and changeable marine environment, with numerous unstable factors such as wind, waves, currents, and ship swaying, personnel face high safety risks during personnel exchanges, and accidents such as falling overboard or collisions can easily occur.

[0003] Currently, personnel transfers are typically carried out using simple ropes or planks, lacking effective protective and securing measures. This makes it impossible to guarantee the stability of personnel during the transfer process. In the event of significant ship swaying or rough seas, personnel can easily lose their balance and fall into the sea. Furthermore, current onboard safety monitoring is inadequate, failing to promptly detect dangers encountered during personnel transfers and take effective countermeasures. This results in delayed rescue efforts in the event of an accident, increasing the risk of casualties. Utility Model Content

[0004] This application provides a safety protection device that can monitor personnel information in a timely manner and reduce the probability of accidents.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] This application provides a safety protection device, including multiple bridge sections, two protective sections, a support section, and a monitoring system. Along a first direction, the multiple bridge sections are nested within each other, and adjacent bridge sections are slidably connected. Both protective sections are located on the upper side of each bridge section, and along a second direction, the two protective sections are located on opposite sides of each bridge section. One end of the support section is retractably located on the lower side of each bridge section, and the other end of the support section is connected to a ship hull to support the bridge section between two ship hulls. The monitoring system includes two monitoring sections and a controller. The two monitoring sections are respectively located on corresponding protective sections. Along the thickness direction of each bridge section, the projection of the monitoring section does not coincide with the projection of the bridge section. The monitoring section is communicatively connected to the controller to transmit monitoring information. The first direction and the second direction are perpendicular to the thickness direction of each bridge section.

[0007] The safety protection device proposed in this application embodiment allows multiple bridge sections to slide and unfold relative to each other when personnel need to be transferred between two vessels. The protection section is installed on the bridge section, and the monitoring section is installed on the protection section. During personnel transfer, the monitoring section can monitor in real time. When abnormal signals such as personnel falling are detected, the monitoring section sends a signal to the controller to take timely rescue measures and reduce personnel injury.

[0008] Optionally, the protective part includes a plurality of protective posts and a fall arrestor. Along the first direction, the plurality of protective posts are spaced apart and detachably disposed on the corresponding bridge body parts, and the fall arrestor is disposed between two adjacent protective posts.

[0011] In the above embodiments, the first monitoring unit and the second monitoring unit are arranged opposite to each other. Both the first monitoring unit and the second monitoring unit can detect personnel information and play a complementary role, thereby improving the accuracy of monitoring and reducing personnel injury to a greater extent.

[0012] Optionally, the monitoring system also includes an alarm unit, which is located on the protective column and is communicatively connected to the controller.

[0013] In the above embodiment, when an abnormal situation such as a person falling is detected, the monitoring unit sends a signal to the controller, the controller transmits the signal to the alarm unit, the alarm unit issues a warning, and notifies the people on board to carry out rescue.

[0014] Optionally, the support includes a plurality of support rods nested together, with adjacent support rods slidably connected.

[0015] In the above embodiments, multiple support rods are nested and slidably arranged to reduce the space occupied by the support parts, and the number of support rods extending can be adjusted according to the height difference between the two vessels, thereby keeping the multiple bridge sections horizontally stable.

[0016] Optionally, the end of the support rod connected to the hull is provided with an anti-slip pad.

[0017] In the above embodiments, the protective pad can increase the friction between the support rod and the hull, thereby reducing the slippage of the support and thus reducing the slippage of the entire safety protection device.

The drive rack is disposed in the first bridge body portion and extends along a first direction. The drive rack meshes with the drive gear.

[0019] In the above embodiment, the drive rack is disposed on the side wall of the first bridge body. When the drive motor drives the drive gear to rotate, the drive gear moves along the drive rack, thereby driving the second bridge body to slide out or retract from the first bridge body, realizing the telescopic arrangement between the first bridge body and the second bridge body.

[0020] Optionally, the plurality of bridge body parts include a first bridge body part, a second bridge body part, and a first driving member. The second bridge body part is embedded in the first bridge body part, the first driving member is disposed in the first bridge body part, and the driving end of the first driving member is connected to the second bridge body part to drive the second bridge body part to extend or retract in a first direction.

[0021] Optionally, the plurality of bridge sections include a third bridge section and a fourth bridge section located at both ends along the first direction, and the lower side of the third bridge section and the fourth bridge section are provided with buffer sections for contacting the hull.

[0022] In the above embodiments, the buffer section is used to reduce the impact between the bridge section and the hull when it comes into contact with the hull, and the buffer section can increase the friction between the bridge section and the hull, thereby reducing the slippage of the bridge section.

[0023] Optionally, the safety protection device also includes ropes disposed on the bridge section for connection to the hull.

[0024] In the above embodiments, ropes are installed in the bridge section to quickly fix the safety protection device to the hull, and can be applied to various types of hulls, thus improving the versatility of the safety protection device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

[0039] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0043] During maritime operations and navigation, situations frequently arise where two vessels approach each other and need to exchange personnel, such as in maritime rescue, resupply, and personnel reassignment. However, due to the complex and changeable marine environment, with its many unstable factors such as wind, waves, currents, and ship swaying, personnel face high safety risks during personnel exchanges, and accidents such as falling overboard or collisions can easily occur.

[0044] Currently, some vessels rely solely on simple ropes or gangplanks for personnel transfer, lacking effective protective and securing measures. This fails to guarantee the stability of personnel during the transfer, making them vulnerable to loss of balance and falls into the sea in the event of significant ship swaying or rough seas. Furthermore, the vessels lack safety monitoring and emergency rescue facilities, hindering the timely detection and response to dangers encountered during personnel transfers. This results in delayed rescue efforts in the event of an accident, increasing the risk of casualties.

[0045] In addition, although some vessels are equipped with safety protection devices, these devices are not versatile and are difficult to adapt to different vessel types and operating environments. Furthermore, the installation and removal of safety protection devices are cumbersome, consuming a lot of time and manpower, which seriously affects operational efficiency.

[0046] In view of this, this application proposes a safety protection device with monitoring function for personnel exchange between two vessels. This safety protection device is safe, reliable, versatile, and easy to operate, and has important practical significance and urgent need for personnel exchange between two vessels at sea.

[0047] This application provides a safety protection device, referencing... Figure 1 and Figure 2 The safety protection device includes multiple bridge sections 1, two protective sections 2, a support section 3, and a monitoring system 4. Along the first direction A, the multiple bridge sections 1 are nested together, and adjacent bridge sections 1 are slidably connected. The two protective sections 2 are both located on the upper side of the bridge section 1. Along the second direction B, the two protective sections 2 are located on opposite sides of the bridge section 1. One end of the support section 3 is retractably located on the lower side of the bridge section 1, and the other end of the support section 3 is connected to the hull to support the bridge section 1 between the two hulls. The monitoring system 4 includes two monitoring sections 41 and a controller. The two monitoring sections 41 are respectively located on the corresponding protective sections 2. Along the thickness direction C of the bridge section 1, the projection of the monitoring section 41 does not coincide with the projection of the bridge section 1. The monitoring section 41 is communicatively connected to the controller to transmit monitoring information to the controller. The first direction A and the second direction B are perpendicular to the thickness direction C of the bridge section 1.

[0048] Multiple bridge sections 1 are nested and fitted together, and adjacent bridge sections 1 can slide and extend. It can be determined whether to fully extend or partially extend the multiple bridge sections 1 as needed, or to nest them together for storage. Nesting the multiple bridge sections 1 reduces the space occupied when they are stored.

[0049] Along the second direction B, multiple protective sections 2 are provided on both sides of the bridge body section 1. When personnel walk on the bridge body section 1, the protective sections 2 can protect them and prevent them from falling. The protective sections 2 can be detachably installed on the bridge body section 1 or can be telescopically installed on the bridge body section 1.

[0050] Multiple support parts 3 are retractable, which can reduce the space occupied by the support parts 3 when they are stored. The support parts 3 can be detachably connected to the bridge body 1 or pivotally connected to the bridge body 1, depending on the specific application.

[0051] Along the thickness direction C of the bridge body 1, the projection of the monitoring unit 41 does not coincide with the projection of the bridge body 1. That is, along the second direction B, the monitoring unit 41 is located on the side of the corresponding protective part 2 away from the bridge body 1. When a person falls from the bridge body 1 or the bridge body 1 shakes excessively, the monitoring unit 41 detects an abnormal signal and transmits the signal to the controller. The controller can issue commands based on the signal to rescue the fallen person. The monitoring unit 41 includes one or more of the following: infrared sensors, optical sensors, and bioelectric sensors.

[0052] The safety protection device proposed in this application embodiment allows multiple bridge sections 1 to slide and unfold relative to each other when personnel need to be transferred between two vessels. A protective section 2 is installed on the bridge section 1, and a monitoring section 41 is installed on the protective section 2. During personnel transfer, the monitoring section 41 can monitor in real time. When abnormal signals such as personnel falling are detected, the monitoring section 41 sends a signal to the controller to take timely rescue measures and reduce personnel injury.

[0053] It should be understood that one of the two adjacent bridge sections 1 is larger than the other, with the smaller bridge section 1 embedded within the larger one. One of the two bridge sections 1 has a groove, and the other has a rail, to achieve a sliding connection between the two adjacent bridge sections 1. The two bridge sections 1 can be deployed as needed to facilitate personnel transfer between the two hulls.

[0054] Optionally, refer to Figure 1 and Figure 2The protective section 2 includes multiple protective posts 21 and fall arrestors (not shown). Along the first direction A, the multiple protective posts 21 are spaced apart and detachably mounted on corresponding bridge sections 1. The fall arrestors are located between adjacent protective posts 21. Each protective section 2 includes multiple protective posts 21, spaced apart along the first direction A. The fall arrestors are located between adjacent protective posts 21. The fall arrestors can be railings connected between adjacent protective posts 21, or fall arrestors connected between adjacent protective posts 21, to protect personnel and reduce the probability of falls. For example, the protective posts 21 may have grooves or through holes for installing railings; or the protective posts 21 may have hooks 22 for installing fall arrestors.

[0055] The height of the protective post 21 is ergonomically designed to effectively prevent accidental climbing. It is also made of high-strength alloy with a corrosion-resistant surface. The protective post 21 is equipped with adjustable hooks 22 for hanging a fall arrest net. The fall arrest net is made of high-strength, wear-resistant fiber material with appropriately sized mesh openings, providing protection without obstructing the view or movement of personnel.

[0056] Optionally, refer to Figure 2 Multiple protective posts 21 include a first protective post 211 and a second protective post 212. Along the first direction A, the first protective post 211 and the second protective post 212 are respectively provided on the corresponding bridge body parts 1 at both ends. Two monitoring units 41 include a first monitoring unit 411 and a second monitoring unit 412. The first monitoring unit 411 is provided on the first protective post 211, and the second monitoring unit 412 is provided on the second protective post 212. Along the first direction A, the first monitoring unit 411 and the second monitoring unit 412 are arranged opposite to each other to form a monitoring area to monitor whether someone has fallen and to transmit the monitoring information to the controller.

[0057] Along the first direction A, a first protective post 211 and a second protective post 212 are respectively provided on the bridge body 1 at both ends. A first monitoring unit 411 is provided on the first protective post 211, and a second monitoring unit 412 is provided on the second protective post 212. The first monitoring unit 411 and the second monitoring unit 412 are arranged opposite to each other. Both the first monitoring unit 411 and the second monitoring unit 412 can detect personnel information and play a complementary role, improving the accuracy of monitoring and thus reducing personnel injury to a greater extent.

[0058] It should be understood that the first protective post 211 and the second protective post 212 are installed at the ends of the plurality of bridge body parts 1 along the first direction A, so that the first monitoring unit 411 and the second monitoring unit 412 can monitor the corresponding two sides of the plurality of bridge body parts 1.

[0059] Optionally, refer to Figure 1 and Figure 2The monitoring system 4 also includes an alarm unit 42, which is located on the protective post 21 and is communicatively connected to the controller. The alarm unit 42 may include warning lights and an alarm. When an abnormal situation such as a person falling is detected, the monitoring unit 41 sends a signal to the controller, which then transmits the signal to the alarm unit 42. The alarm unit then sounds an alarm, the warning lights flash, and the personnel on board are notified to carry out rescue operations.

[0060] Reflective markings can also be installed on the protective section 2 to serve as a warning at night or in inclement weather conditions and improve visibility.

[0061] In one optional embodiment, the safety protection device further includes an emergency rescue system connected to the control communication network. The emergency rescue system includes various emergency rescue devices, such as automatically inflatable lifebuoys and rescue ropes. These devices are installed on both sides of multiple bridge sections 1, making them easily accessible and simple to operate. Upon receiving a signal, the controller will quickly activate the emergency rescue devices. For example, the automatically inflatable lifebuoy will automatically inflate and pop out, and the rescue rope will automatically lower, facilitating self-rescue or waiting for rescue.

[0062] Optionally, refer to Figure 2 The support section 3 includes multiple support rods 31 nested together, with adjacent support rods 31 slidably connected. The nesting and sliding arrangement of multiple support rods 31 reduces the space occupied by the support section 3, and the number of support rods 31 extending can be adjusted according to the height difference between the two hulls, thereby keeping the multiple bridge sections 1 horizontally stable.

[0063] Multiple support rods 31 are nested together and slidably connected. The sliding between the support rods 31 can be manually driven, or the multiple support rods 31 can be telescopically slidable through an electric push rod.

[0064] Optionally, the end of the support rod 31 connected to the hull is provided with an anti-slip pad (not shown). A protective pad is provided at the bottom of the support rod 31 where it connects to the hull, which increases the friction between the support rod 31 and the hull, thereby reducing the sliding of the support part 3 and thus reducing the sliding of the entire safety protection device. Furthermore, the protective pad can effectively absorb the energy generated by hull swaying and wave impact, reducing the impact of hull swaying and wave impact on the bridge part 1, further improving the stability of the safety protection device.

[0065] Optionally, refer to Figure 1 and Figure 2The multiple bridge sections 1 include a first bridge section, a second bridge section, and a first drive mechanism 5. The second bridge section is embedded within the first bridge section. The first drive mechanism 5 includes a drive motor 51 and a drive rack 53. The drive motor 51 is disposed in the second bridge section, and a drive gear 52 is provided on the drive shaft of the drive motor 51. The drive rack 53 is disposed within the first bridge section and extends along a first direction A, meshing with the drive gear 52. The drive rack 53 is disposed on the side wall of the first bridge section. When the drive motor 51 drives the drive gear 52 to rotate, the drive gear 52 moves along the drive rack 53, thereby driving the second bridge section to slide out or retract from the first bridge section, realizing the retractable arrangement between the first bridge section and the second bridge section.

[0066] For example, each end of the drive shaft of the drive motor 51 is connected to a drive gear 52, and the side wall of the first bridge body is provided with two drive racks 53 spaced apart along the second direction B. The drive racks 53 cooperate with the drive gears 52 to improve the stability of the sliding when the second bridge body automatically extends or retracts.

[0067] In this application, the second bridge body is driven to move by the cooperation of the drive rack 53 and the drive gear 52, so that the second bridge body is very stable during the movement, thus ensuring the stability of the movement of the second bridge body.

[0068] It should be understood that a sliding rail mating structure is provided between the first bridge body and the second bridge body to make it easier for the second bridge body to slide out of the first bridge body.

[0069] Optionally, refer to Figure 1 and Figure 2 The plurality of bridge sections 1 include a first bridge section, a second bridge section, and a first driving member 6. The second bridge section is embedded within the first bridge section, and the first driving member 6 is disposed in the first bridge section. The driving end of the first driving member 6 is connected to the second bridge section to drive the second bridge section to extend or retract along a first direction A. For example, the first driving member 6 is an electric actuator. The fixed end of the electric actuator is connected to the first bridge section, and the driving end of the electric actuator is connected to the second bridge section to drive the second bridge section to extend or retract from the first bridge section. The structure of the electric actuator is simpler than that of a gear and rack structure and does not occupy space.

[0070] It should be understood that the first drive mechanism 5 and the first drive member 6 can be used in combination or individually as needed. For example, each of two adjacent bridge body parts 1 can be connected by the first drive mechanism 5, or each of two adjacent bridge body parts 1 can be connected by the first drive member 6, or some of two adjacent bridge body parts 1 can be connected by the first drive mechanism 5 and some of two adjacent bridge body parts 1 can be connected by the first drive member 6.

[0071] Optionally, refer to Figure 2 The plurality of bridge sections 1 include a third bridge section 11 and a fourth bridge section 12 located at both ends along the first direction A. Both the third bridge section 11 and the fourth bridge section 12 have a buffer section 7 on their lower sides for contacting the hull. The buffer section 7 reduces the impact between the bridge section 1 and the hull when contacting the hull, and also increases the friction between the bridge section 1 and the hull, thereby reducing the slippage of the bridge section 1.

[0072] In an optional embodiment, along the thickness direction C of the bridge body 1, the buffer part 7 has a recess on the side away from the bridge body 1. The buffer part 7 can be made of plastic material. When the bridge body 1 is supported on the hull, the buffer part 7 contacts the hull, and the edge of the buffer part 7 contacts the hull and squeezes the air in the recess outward, so that the buffer part 7 is attached to the hull like a suction cup, thereby improving the stability of the bridge body 1.

[0073] Optionally, the safety protection device also includes a rope (not shown) disposed on the bridge section 1 for connecting to the hull. The rope, disposed on the bridge section 1, is used to quickly secure the safety protection device to the hull and is applicable to various types of hulls, thus improving the versatility of the safety protection device.

[0074] In an optional embodiment, the bridge body 1 is further provided with reinforcing ribs to enhance its structural strength and enable it to withstand the passage of a certain weight of personnel and goods.

[0075] This application comprehensively ensures the safety of personnel during the exchange between two vessels by installing protective posts 21, fall protection nets, warning lights, reflective markings, and automatically activated emergency rescue equipment, effectively reducing the probability of accidents. The ropes connected to the bridge section 1 and the adjustable support section 3 can adapt to different vessel types and operating environments, increasing the applicability of the safety protection device. Furthermore, the installation and dismantling of this safety protection device is simple and quick, saving significant time and manpower and improving operational efficiency. The monitoring system 4 can monitor the status of personnel and equipment in real time, promptly detect hazards, and take effective emergency measures to minimize casualties and property damage.

[0076] Before personnel begin exchanging personnel between vessels using safety protection devices, the monitoring system 4 and emergency rescue system are activated to conduct a comprehensive inspection of the safety protection devices, ensuring that all parts are functioning properly. At the same time, personnel are reminded to wear personal protective equipment, such as life jackets.

[0077] When personnel walk on bridge section 1, monitoring system 4 monitors their position and walking status in real time. If a person slips or experiences other abnormalities, the infrared sensor will immediately detect it and transmit a signal to the controller. Upon receiving the signal, the controller will quickly activate emergency rescue equipment. For example, the automatic inflatable lifebuoy will automatically inflate and deploy, and the rescue rope will automatically lower, facilitating self-rescue or waiting for rescue. Simultaneously, warning lights will flash, and an alarm will sound to notify personnel on board to initiate rescue.

[0078] After the personnel exchange between the vessels is completed, first shut down the monitoring system 4 and the emergency rescue system, and disconnect the connection lines of the relevant equipment. Then, dismantle the protective section 2, first removing the fall arrest net from the protective post 21 and organizing and storing it. Next, remove the protective post 21 from the bridge section 1 and store it properly. Then, adjust the length of the support section 3 to shorten it and remove it from contact with the ship's deck. Then, disconnect the quick-connect mechanisms, such as ropes, between both ends of the bridge section 1 and the hull, and remove the bridge section 1 from the hull. Finally, clean, inspect, and maintain the entire safety protection device, and store all components properly.
