Description

Technical Field

[0001] This utility model belongs to the field of marine technology, and more specifically, it relates to a protective device for entering and exiting anti-piracy cabins on ships. Background Technology

[0002] In existing technology, the doors to anti-piracy compartments are a critical but also vulnerable point in a ship's anti-piracy efforts. To effectively prevent and delay pirates from entering these compartments, access doors are typically made of steel. However, fire separation requirements sometimes necessitate the installation of fire-resistant doors such as AO or A60 grade doors, making it impossible to install additional steel doors. A drawback of existing technology is that since most anti-piracy compartments are currently located in the steering gear room, and in some ships the steering gear room and engine room are connected, the doors in these areas are often custom-made compartment doors, whose strength cannot guarantee crew safety.

[0003] Existing technology includes a device titled "Anti-piracy Cabin Access Protection Device for Ships," with publication number CN109094731B. This device discloses an anti-piracy cabin access protection device for ships, comprising a steel door back panel matching the dimensions of the anti-piracy cabin access door, fasteners, an electromagnetic adsorption device, and an electromagnetic adsorption control unit. The door back panel is detachably connected to the inner wall of the cabin. The electromagnetic adsorption device is installed on the inner walls around the access door. The electromagnetic adsorption control unit is connected to the electromagnetic adsorption device and controls its energization. The detachable anti-piracy steel door back panel not only achieves the same protection requirements as a steel door panel but is also easy to install, allowing for quick installation by a single person in an emergency. Furthermore, the use of electromagnetic adsorption to fix the door back panel to the inner walls around the access door offers advantages such as rapid fixing and quick and easy operation, effectively saving time and quickly completing cabin door protection. It effectively prevents unauthorized personnel from entering, protecting the crew and extending rescue time.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a ship anti-piracy compartment access protection device that is simple in structure, applicable to different ship anti-piracy compartments, meets ship safety requirements, and is convenient and quick to open and close, in order to address the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model is a protective device for entering and exiting a ship's anti-piracy cabin. A motor is installed on the door panel, and the motor's lifting rope is connected to the upper platform. An eye ring is set on the upper side of the door panel, and a push rod is set on the side of the upper platform. An eye ring is set on the lower side of the door panel, and a push rod is set on the side of the lower platform.

[0008] The side of the door panel is movably fitted into the slide groove.

[0009] A base plate is installed on the lower platform, a gravity sensor is installed on the base plate, and a push rod is installed on the side of the base plate.

[0010] The motor, push rod, and gravity sensor are respectively connected to the control components.

[0011] A limit switch is installed at the position of the upper platform.

[0012] Each side of the upper part of the door panel is provided with an eye ring, and each side of the upper platform is provided with a push rod.

[0013] Each side of the lower part of the door panel is provided with an eye ring, and each side of the bottom plate is provided with a push rod.

[0014] Each side of the door panel is equipped with multiple pulleys at intervals.

[0015] The door panel includes a front panel and a rear panel, which are fixedly connected by multiple connecting ribs 14.

[0016] A support plate is provided on the side of the door panel, and the motor is fixed on the support plate.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The anti-piracy cabin access protection device for ships described in this utility model features a movable door panel installed within a sliding track. This door panel can move up and down relative to the track. A motor is mounted on the door panel, and its lifting rope is connected to an upper platform. As the motor rotates in different directions, it can rewind or unwind the lifting rope, causing the door panel to move up and down relative to the track. An eye ring is installed on the upper side of the door panel, and a push rod is installed on the side of the upper platform. When the door panel is open and in the upper position, the push rod is controlled to insert into the corresponding eye ring on the upper part of the door panel, thus limiting the door panel and preventing it from easily falling. Similarly, an eye ring is installed on the lower side of the door panel, and a push rod is installed on the side of the lower platform. When the door panel is closed and in the lower position, the push rod is controlled to insert into the corresponding eye ring on the lower part of the door panel, thus limiting the door panel and preventing it from easily opening. Therefore, the main components of this utility model include a door panel, a motor, a sliding track, a gravity sensor, and a propulsion and fixing device (eye ring and push rod). The thickness of the door panel can be adjusted according to requirements, and a reinforcing structure can be added to the door panel. The lifting mechanism uses a motor. The slideway can be made of channel steel or angle steel, making material selection and installation convenient. The push rod is connected to the control components of the motor and gravity sensor respectively, realizing functional interlocking, high degree of automation, and fast and flexible operation.

[0024] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0025] As attached Figure 1 -Appendix Figure 3 As shown, this utility model is a protective device for entering and exiting a ship's anti-piracy cabin. A motor 3 is installed on the door panel 1, and the lifting rope 10 of the motor 3 is connected to an upper platform 11. An eye ring 6 is provided on the upper side of the door panel 1, and a push rod 5 is provided on the side of the upper platform 11. An eye ring 6 is also provided on the lower side of the door panel 1, and a push rod 5 is provided on the side of the lower platform. To address the shortcomings of existing technologies, an improved technical solution is proposed. In this structural design, a movable door panel is installed within a sliding groove, allowing the door panel to move up and down relative to the groove. The motor 3 is installed on the door panel 1, and the lifting rope 10 of the motor 3 is connected to the upper platform 11. When the motor rotates in different directions, it can rewind or unwind the lifting rope, causing the door panel to move up and down relative to the groove. An eye ring 6 is provided on the upper side of the door panel 1, and a push rod 5 is provided on the side of the upper platform 11. When the door panel 1 is open and in the upper position, the push rod 5 at the top is controlled to insert into the corresponding eye ring 6 at the top of the door panel 1, thus limiting the door panel 1 and preventing it from easily falling off. A locking ring 6 is installed on the lower side of the door panel 1, and a push rod 5 is installed on the lower platform side. When the door panel 1 is closed and in the lower position, the push rod 5 at the lower part is controlled to insert into the corresponding locking ring 6 at the lower part of the door panel 1, thereby limiting the door panel 1 and preventing it from opening easily. Therefore, the main components of this utility model include the door panel 1, motor 3, slide 2, gravity sensor 8, and propulsion fixing device (locking ring 6 and push rod 5). The thickness of the door panel 1 can be adjusted according to requirements, and a reinforcing structure can be added to the door panel 1. The lifting mechanism uses the motor 3. The slide 2 can be made of channel steel or angle steel, which is convenient for material selection and installation. The push rod 5 is connected to the control components of the motor 3 and gravity sensor 8 respectively to achieve functional interlocking, high degree of automation, and fast and flexible operation. The anti-piracy cabin access protection device of this utility model has a simple structure, can be applied to different anti-piracy cabins of ships, meets the ship safety requirements, and is convenient and quick to open and close.

[0026] The door panel 1 is movably fitted into the slide groove 2 on its side. In the above structure, each side of the door panel is provided with a slide groove 2, which reliably limits the position of the front, rear and side of the door panel 1, ensuring that the door panel 1 can only move up and down along the direction defined by the slide grooves 2 on both sides when it is opened or closed.

[0027] During the door opening process, the door panel is raised to the limit device by the action of the motor and the pulleys on both sides of the door panel through the sliding groove. After the door panel is pulled up to the limit position, the limit device transmits a signal to activate the push rods on both sides above. The push rods are sensed and pop out and insert into the eye rings on the upper part of the door panel. At this time, the door panel is in the fully open state, and the push rods ensure that the door panel will not easily fall down after it is opened.

[0028] A base plate 7 is installed on the lower platform, and a gravity sensor 8 is installed on the base plate 7. A push rod 5 is installed on the side of the base plate 7. The motor 3, push rod 5, and gravity sensor 8 are respectively connected to the control components. In the above structure, during the closing process of the door panel 1, the motor 3 is started, and the upper push rod 5 receives a signal from the control components and retracts inward. The push rod 5 exits the eye ring 6, releasing the limitation on the door panel 1. Under the action of the motor and the pulleys on both sides of the door panel, the door panel 1 descends to the base plate 7 through the slide groove 2. After the door panel 1 descends to the bottom, the gravity sensor 8 receives pressure and transmits a signal to the lower push rod 5. The push rod 5 senses the pressure, pops out, and inserts into the eye ring 6 at the bottom of the door panel, thereby limiting the closed door panel 1 and ensuring that the door panel 1 will not be easily opened after it is closed.

[0029] A limiter 9 is installed at the upper platform 11. In the above structure, during the upward opening process of the door panel, after moving to the upper position, it contacts the limiter, and the limiter restricts the highest position of the door panel.

[0030] Each side of the upper part of the door panel 1 is provided with an eye ring 6, and each side of the upper platform 11 is provided with a push rod 5. Each side of the lower part of the door panel 1 is provided with an eye ring 6, and each side of the bottom plate 7 is provided with a push rod 5. This structure, with push rods and eye rings on both sides, reliably ensures the limiting reliability when the door panel is opened or closed. Multiple pulleys 4 are provided on each side of the door panel 1 at intervals. The pulleys 4 effectively reduce the resistance when the door panel 1 is raised or lowered.

[0031] The door panel 1 includes a front panel 12 and a rear panel 13, which are fixedly connected by multiple connecting ribs 14. With this structure, the door panel thickness can be set as needed.

[0032] The door panel 1 has a support plate 15 on its side, and the motor 3 is fixed on the support plate 15.

[0033] The anti-piracy cabin access protection device for ships described in this utility model has the following structural design: a movable door panel is installed within a sliding track, allowing the door panel to move up and down relative to the track. A motor 3 is installed on the door panel 1, and the lifting rope 10 of the motor 3 is connected to an upper platform 11. When the motor rotates in different directions, it can rewind or unwind the lifting rope, causing the door panel to move up and down relative to the track. An eye ring 6 is installed on the upper side of the door panel 1, and a push rod 5 is installed on the side of the upper platform 11. When the door panel 1 is open and in the upper position, the push rod 5 is controlled to insert into the corresponding eye ring 6 on the upper part of the door panel 1, thus limiting the door panel 1 and preventing it from easily falling off. An eye ring 6 is also installed on the lower side of the door panel 1, and a push rod 5 is installed on the side of the lower platform. When the door panel 1 is closed and in the lower position, the push rod 5 is controlled to insert into the corresponding eye ring 6 on the lower part of the door panel 1, thus limiting the door panel 1 and preventing it from easily opening. Therefore, the main components of this utility model include a door panel 1, a motor 3, a slide rail 2, a gravity sensor 8, and a propulsion fixing device (eye ring 6 and push rod 5). The thickness of the door panel 1 can be adjusted according to requirements, and a reinforcing structure can be added to the door panel 1. The lifting mechanism uses the motor 3. The slide rail 2 can be made of channel steel or angle steel, which is convenient for material selection and installation. The push rod 5 is connected to the control components of the motor 3 and the gravity sensor 8 respectively, realizing functional interlocking, high degree of automation, and fast and flexible operation.
