Technical Field

[0001] This utility model relates to a ship life raft release mechanism, and more particularly to an automatic release tilting mechanism for a ship life raft. Background Technology

[0002] As the International Maritime Organization (IMO) continues to raise its standards for maritime safety, the performance requirements for ship lifesaving equipment are becoming increasingly stringent. Life rafts, as crucial equipment for protecting the lives of crew and passengers in emergencies, have release mechanisms whose reliability and efficiency directly impact the success or failure of rescue operations. Traditional life raft release devices often rely on manual operation, which may pose risks of untimely or inaccurate operation in emergencies.

[0003] In emergency situations such as shipwrecks, manually launching life rafts is inefficient and slow to respond, which may delay rescue opportunities and endanger the lives of personnel. Utility Model Content

[0004] The main purpose of this utility model is to provide an automatic release tilting mechanism for ship life rafts to solve the problems raised in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, an automatic release tilting mechanism for a ship's life raft is provided, comprising two fixed plates symmetrically fixed on a ship, a raft frame for placing a life raft rotatably disposed between the two fixed plates, sliders symmetrically fixed on both sides of the raft frame, a first groove and a second groove symmetrically opened on one side of each fixed plate, the sliders being slidably installed in the first groove and the second groove respectively, and a booster structure fixedly disposed on the raft frame, wherein when the raft frame tilts, the booster structure is used to push the life raft to roll off the raft frame.

[0006] Furthermore, the raft frame includes a support frame, which is arc-shaped, and connecting plates are fixedly connected to both sides of the support frame, with the slider fixedly disposed at both ends of the connecting plates.

[0007] Furthermore, a connecting shaft is fixedly connected to the side wall of the connecting plate, and the connecting shaft is rotatably installed inside the fixed plate. A motor is fixedly installed on one side wall of the fixed plate, and the output shaft of the motor is fixedly connected to the connecting shaft on that side.

[0008] Furthermore, both the first and second slides are arc-shaped, and the fixed plate has symmetrically formed grooves that communicate with the upper end of the first slide. A spring is fixedly installed in the groove, one end of the spring is fixedly connected to the side wall of the groove, and the other end is fixedly connected to a first metal sheet, which is located at the upper end of the first slide.

[0009] Furthermore, the booster structure includes at least a cylinder fixedly disposed at the middle position on one side of the support frame, and also includes a second metal plate embedded and fixedly disposed on the slider on that side.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In the automatic release and tilting mechanism of the ship's life raft, the motor is connected to the connecting shaft and installed on the fixed plate.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] like Figures 1 to 6 As shown, this embodiment provides an automatic release tilting mechanism for a ship's life raft, including two fixed plates 1 symmetrically fixed on the ship. A raft frame 2 for placing a life raft 3 is rotatably arranged between the two fixed plates 1. Slider blocks 23 are fixedly and symmetrically fixed on both sides of the raft frame 2. A first sliding groove 11 and a second sliding groove 12 are symmetrically opened on one side of the fixed plates 1. The sliders 23 are slidably installed in the first sliding groove 11 and the second sliding groove 12 respectively. A booster structure is fixedly arranged on the raft frame 2. When the raft frame 2 tilts, the booster structure is used to push the life raft 3 to roll off the raft frame 2.

[0025] like Figure 1 and Figure 2 As shown, the ship is equipped with a power supply;

[0026] The raft frame 2 includes a support frame 21, which is arc-shaped. This shape can better fit the bottom contour of the life raft 3 and provide stable support for the life raft 3. When the life raft 3 is placed, the arc-shaped structure can form a good contact surface between the life raft 3 and the support frame 21, increasing the friction. Both sides of the support frame 21 are fixedly connected to connecting plates 22, and the sliders 23 are fixedly installed at both ends of the connecting plates 22.

[0027] like Figure 2 As shown, it is worth noting that the bottom of the support frame 21 has several through holes. When the ship is sailing on the water, especially in rough sea conditions, the swaying is more violent, and a small amount of seawater may splash onto the raft frame 2. The through holes at the bottom of the support frame 21 can drain this seawater in time, preventing seawater from accumulating inside the support frame 21. If seawater accumulates inside the raft frame 2 for a long time, it will not only increase the weight of the raft frame 2, affecting its normal function and stability, but may also cause corrosion and other damage to the life raft 3, reducing the service life and reliability of the life raft 3.

[0028] like Figure 1 and Figure 2As shown, a connecting shaft 25 is fixedly connected to the side wall of the connecting plate 22. The connecting shaft 25 is rotatably installed in the fixed plate 1. A motor 4 is fixedly installed on the side wall of one of the fixed plates 1. The output shaft of the motor 4 is fixedly connected to the connecting shaft 25 on that side. When it is necessary to release the life raft 3, the motor 4 is started, and the output shaft of the motor 4 begins to rotate. Since the output shaft of the motor 4 is fixedly connected to the connecting shaft 25, it drives the connecting shaft 25 to rotate. The rotation of the connecting shaft 25 drives the connecting plate 22, which is fixedly connected to it, to move. This causes the entire raft frame 2 to rotate around the connecting shaft 25. As the raft frame 2 rotates, the raft frame 2 gradually tilts. Since the life raft 3 is placed on the support frame 21 of the raft frame 2, when the raft frame 2 tilts to a certain extent, the life raft 3 slides down the arc surface of the raft frame 2 under the action of gravity and is finally released from the raft frame 2 onto the water surface, completing the release process of the life raft 3.

[0029] The motor 4 is equipped with a protective cover. During ship navigation, the environment is complex, and there may be situations such as seawater splashing and collisions with debris. The protective cover can effectively prevent seawater from directly contacting the motor 4, preventing safety hazards such as short circuits and damage caused by water ingress.

[0030] like Figure 4 and Figure 5 As shown, both the first slide groove 11 and the second slide groove 12 are arc-shaped, and the fixing plate 1 is symmetrically provided with grooves 15 that communicate with the upper end of the first slide groove 11. A spring 14 is fixedly installed in the groove 15. One end of the spring 14 is fixedly connected to the side wall of the groove 15, and the other end is fixedly connected to a first metal plate 13, which is located at the upper end of the first slide groove 11.

[0031] like Figure 2 , Figure 3 As shown, the booster structure includes at least a cylinder 5 fixedly disposed at the middle position on one side of the support frame 21, and also includes a second metal plate 231 embedded and fixedly disposed on the slider 23.

[0032] The starter motor 4 drives the raft frame 2 to rotate, causing it to tilt. The slider 23 at one end of the raft frame 2 slides upwards along the first slide groove 11 until the second metal plate 231 on the slider 23 contacts the first metal plate 13. The slider 23 at the other end of the raft frame 2 slides downwards along the second slide groove 12. A power supply is installed inside the fixing plate 1. The first metal plate 13 is connected to the negative terminal of the power supply inside the fixing plate 1 via a wire, and the second metal plate 231 is connected to the positive terminal of the power supply inside the fixing plate 1 via a wire. The first metal plate 13, the second metal plate 231, the cylinder 5, and the power supply are connected by wires to form a complete series circuit. When the second metal plate 231 contacts the first metal plate 13, the circuit is completed, opening the cylinder 5 and driving the output shaft of the cylinder 5 to extend, thus pushing... The life raft 3 quickly rolls down the arc surface of the support frame 21 to the water surface, completing the release process of the life raft 3. The spring 14 in the groove 15 plays a role in buffering and maintaining contact. When the second metal plate 231 contacts the first metal plate 13, the spring 14 is compressed and generates a certain elastic force. This elastic force can ensure that the first metal plate 13 and the second metal plate 231 are in close contact for a period of time, ensuring that the circuit can be stably conducted, thereby reliably triggering the cylinder 5 and pushing the life raft 3 to roll down quickly. The cylinder 5 is automatically triggered by the sliding of the slider 23 and the contact of the metal plates, without the need for manual intervention. This improves the automation level and response speed of the life raft 3 release, and can release the life raft 3 more quickly in emergency situations to ensure the safety of personnel.

[0033] In practical use, when an emergency requires the release of the life raft 3, the motor 4 is started. Since the output shaft of the motor 4 is fixedly connected to the connecting shaft 25, the connecting shaft 25 is rotated. The rotation of the connecting shaft 25 in turn causes the connecting plate 22, which is fixedly connected to it, to rotate, thereby causing the entire raft frame 2 to rotate around the connecting shaft 25, and the raft frame 2 to gradually tilt. During the tilting process of the raft frame 2, the slider 23 at one end of the raft frame 2 slides upward along the first slide groove 11, and the slider 23 at the other end slides downward along the second slide groove 12. When the second metal piece 231 on the slider 23 sliding upward along the first slide groove 11 contacts the first metal piece 13 located at the upper end of the first slide groove 11, since the first metal piece 13 is connected to the negative terminal of the power supply in the fixed plate 1 through a wire, and the second metal piece 231 is connected to the positive terminal of the power supply in the fixed plate 1 through a wire, the circuit is turned on, the switch of the cylinder 5 is opened, the output shaft of the cylinder 5 extends rapidly, and applies a thrust to the life raft 3, pushing the life raft 3 to roll quickly down the arc surface of the support frame 21; under the combined action of gravity and the thrust of the cylinder 5, the life raft 3 smoothly slides down the arc surface of the support frame 21 to the water surface, completing the release process of the life raft 3; after the life raft 3 is released, the motor 4 can be controlled to rotate in the opposite direction according to the actual situation, so that the raft frame 2 rotates in the opposite direction around the connecting shaft 25, returning to the initial horizontal or near-horizontal state, waiting for the next use.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
