[0002] The low-temperature shock-absorbing base for lifeboats on hybrid cable-laying vessels is a core auxiliary device adapted to the operational scenarios and low-temperature environments of hybrid cable-laying vessels. Its core function is to provide a stable foundation for lifeboats, while the integrated shock-absorbing structure reduces the impact of turbulence during ship navigation and cable-laying operations, preventing structural cracking or jamming in low-temperature environments. This ensures the structural integrity and stability of lifeboats during storage, without affecting the rapid release of lifeboats in emergencies, and ensures the normal functioning of lifesaving capabilities under extreme conditions.

[0003] To address the aforementioned issues, existing patents offer solutions. Most existing lifeboat shock-absorbing support seats rely on springs for shock absorption. However, over time, spring-supported systems may become brittle due to their inherent characteristics.

[0004] To address this, a low-temperature vibration damping seat for a hybrid cable-laying ship lifeboat frame is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a low-temperature shock-absorbing seat for a hybrid cable-laying boat lifeboat frame, which can solve the problem that most existing lifeboat shock-absorbing support seats rely on spring support for shock absorption, and that spring support may become brittle over time due to its own characteristics.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature shock-absorbing seat for a hybrid cable-laying boat lifeboat frame, comprising a shock-absorbing component, wherein a limit component is provided on the top of the shock-absorbing component, and a mounting plate is bolted to the bottom of the shock-absorbing component; The shock absorption assembly includes a housing, a spring structure fixedly connected to the bottom of the inner wall of the housing, an adjusting plate fixedly connected to the top of the spring structure, two spring bodies fixedly connected inside the adjusting plate, mounting brackets fixedly connected to opposite sides of the two spring bodies, first semi-metal friction plates fixedly connected inside the two mounting brackets, a second semi-metal friction plate fixedly connected inside the housing to cooperate with the two first semi-metal friction plates, a pressure relief valve connected inside the housing, and a protective shell covering the surface of the housing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 The present invention provides the following technical solution: A low-temperature shock-absorbing seat for a hybrid cable-laying boat lifeboat frame includes a shock-absorbing component 1, a limit component 2 is provided on the top of the shock-absorbing component 1, and a mounting plate 3 is bolted to the bottom of the shock-absorbing component 1. The shock absorption assembly 1 includes a housing 101. A spring structure 102 is fixedly connected to the bottom of the inner wall of the housing 101. An adjusting plate 103 is fixedly connected to the top of the spring structure 102. Two spring bodies 104 are fixedly connected inside the adjusting plate 103. Mounting brackets 105 are fixedly connected to opposite sides of the two spring bodies 104. First semi-metal friction plates 106 are fixedly connected inside the two mounting brackets 105. Second semi-metal friction plates 107 that cooperate with the two first semi-metal friction plates 106 are fixedly connected inside the housing 101. A pressure relief valve 108 is connected inside the housing 101. A protective shell 109 is fitted on the surface of the housing 101.

[0019] In this embodiment: The shock-absorbing component 1, a core shock-absorbing structure, weakens the impact of ship turbulence and is suitable for low-temperature environments. The limiting component 2 fixes the position of the lifeboat, preventing displacement during storage or turbulence. The mounting plate 3 connects the shock-absorbing component 1 to the hull, achieving overall fixation of the shock-absorbing seat. The housing 101 supports the internal shock-absorbing components and provides an installation foundation. The spring structure 102, the main shock-absorbing element, buffers longitudinal impact forces. The adjusting plate 103 transmits the shock-absorbing force of the spring structure 102. The spring body 104 is installed, providing auxiliary shock absorption. The first semi-metal friction plate 106 is pushed to fit against the second semi-metal friction plate 107. The first semi-metal friction plate 106 is fixed by the mounting bracket 105 to ensure a stable installation. The first semi-metal friction plate 106 and the second semi-metal friction plate 107 cooperate to consume vibration energy through friction. The second semi-metal friction plate 107 cooperates with the first semi-metal friction plate 106 to enhance the shock absorption effect. The pressure relief valve 108 is set to balance the internal pressure of the housing 101 to avoid excessive pressure affecting the operation of the components. The protective shell 109 is set to wrap the housing 101 and provide external protection.

[0020] Specifically, such as Figure 3 As shown, the limiting component 2 includes an adjustment groove 201, with a bidirectional spiral rod 202 threadedly connected inside the adjustment groove 201. Two adjusting blocks 203 are threadedly connected to the surface of the bidirectional spiral rod 202, and a limiting frame 204 is fixedly connected to the top of each of the two adjusting blocks 203.

[0021] Specifically, such as Figure 3 As shown, protective plates 205 are fixedly connected to the opposite sides of the two limit frames 204, and both protective plates 205 are made of low-temperature resistant rubber.

[0022] Specifically, such as Figure 3 As shown, the surface of the bidirectional helical rod 202 is threadedly connected to a limiting threaded disc 206, and the left side of the limiting threaded disc 206 contacts the right side of the housing 101.

[0023] In this embodiment: by setting the adjustment groove 201, installation and adjustment space is provided for the bidirectional spiral rod 202; by setting the bidirectional spiral rod 202, the adjustment block 203 is driven to move relative to or in opposite directions to adjust the limiting width; by setting the adjustment block 203, the bidirectional spiral rod 202 is connected to the limiting frame 204 to transmit adjustment power; by setting the limiting frame 204, the lifeboat is directly limited to avoid lateral displacement; by setting the protective plate 205, it fits the lifeboat to avoid hard contact damage, is resistant to low temperature and brittleness; by setting the limiting threaded plate 206, the position of the bidirectional spiral rod 202 is fixed to prevent loosening after adjustment.

[0024] Specifically, such as Figure 6As shown, auxiliary plates 4 are fixedly connected to the left and right sides of the protective shell 109, and connecting plates 5 are fixedly connected to the left and right sides of the box shell 101. Threaded rods 6 are threadedly connected to the inner walls of the two connecting plates 5.

[0025] Specifically, such as Figure 6 As shown, buffer frames 7 are fixedly connected to the top of both threaded rods 6, and adjustment knobs 8 are fixedly connected to the bottom of both threaded rods 6.

[0026] In this embodiment: by setting an auxiliary plate 4, in conjunction with a connecting plate 5 and a threaded rod 6, the connection stability between the protective shell 109 and the housing 101 is enhanced. By setting a connecting plate 5, an installation interface for the threaded rod 6 is provided to connect the housing 101 and the auxiliary plate 4. By setting a threaded rod 6, the height of the buffer frame 7 is adjusted to adapt to different installation requirements or to compensate for shock absorption gaps. By setting a buffer frame 7, a certain amount of swaying space is limited when there is significant shaking. By setting an adjustment knob 8, the height of the threaded rod 6 can be easily adjusted manually.

[0027] Specifically, such as Figure 4 As shown, the surface of the housing 101 is coated with a low-temperature resistant coating 9, and the surface of the protective shell 109 is sprayed with a corrosion-resistant coating 10.

[0028] Specifically, such as Figure 5 As shown, a protective post 11 is fixedly connected to the bottom of the inner wall of the housing 101. The protective post 11 is made of rubber.

[0029] In this embodiment: by setting a low-temperature resistant coating 9 and applying it to the surface of the shell 101, the low-temperature resistance of the shell 101 is improved and brittleness is prevented. By setting a corrosion resistant coating 10 and spraying it on the surface of the protective shell 109, the corrosion of the marine environment is resisted and the service life is extended. By setting a protective post 11 located at the bottom of the shell 101 and made of rubber, it plays a bottom buffering and protection role, preventing the adjustment plate 103 from moving down too far and colliding with the shell 101.

[0030] Working principle: The device is fixed to a designated position on the hull of the hybrid cable-laying vessel by the mounting plate 3. First, the bidirectional spiral rod 202 is rotated, causing the threads on its surface to drive the two adjusting blocks 203 to move the limiting frame 204 relative to each other until the low-temperature resistant rubber protective plate 205 on the inner side of the limiting frame 204 is tightly attached to the side wall of the lifeboat, completing the lateral limiting of the lifeboat. Then, the limiting threaded disc 206 on the surface of the bidirectional spiral rod 202 is tightened, so that its left side is in close contact with the right side of the housing 101, fixing the position of the bidirectional spiral rod 202 to prevent loosening. When the ship is sailing or during cable-laying operations, the shock absorption component 1 is activated. The spring structure 102 inside the housing 101 first provides initial buffering of the longitudinal impact force. At the same time, the adjusting plate 103 moves up and down with the vibration. During the displacement of the adjusting plate 103, the two spring bodies 104 inside it change their force state, pushing the mounting frame 105 and the first semi-metal friction plate 106 inside the frame to move synchronously, so that the first semi-metal friction plate 106 is fixed to the inner wall of the housing 101. The two semi-metal friction plates 107 always maintain a tight fit. During their relative sliding, the friction between them generates heat, which helps to alleviate the risk of component embrittlement in low-temperature environments. At the same time, the friction consumes a large amount of vibration energy, further reducing the impact of turbulence on the lifeboat. During this process, the pressure relief valve 108 connected to the shell 101 balances the internal pressure in real time to prevent excessive pressure from interfering with the operation of components. The low-temperature resistant coating 9 on the surface of the shell 101 and the corrosion-resistant coating 10 sprayed on the surface of the protective shell 109 respectively resist the corrosion of low temperature and marine environment. The rubber protective post 11 at the bottom of the inner wall of the shell 101 prevents the adjusting plate 103 from moving too low and colliding with the shell 101. In addition, the height of the threaded rod 6 can be adjusted by rotating the adjusting knob 8, which drives the buffer frame 7 to adapt to the installation gap or limit the range of shaking of the device, ultimately achieving stable shock absorption and safe fixation of the lifeboat in low-temperature environments. At the same time, the friction between the first semi-metal friction plate 106 and the second semi-metal friction plate 107 generates heat to help deal with the problem of low-temperature embrittlement.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
