Description

Technical Field

[0001] This utility model relates to a strengthening device, specifically a strengthening device for the engine body of a marine hydrogen internal combustion engine, belonging to the field of hydrogen internal combustion engine strengthening technology. Background Technology

[0002] Marine hydrogen internal combustion engines are traditional reciprocating internal combustion engines that use hydrogen as fuel. They generate power by directly burning hydrogen and their biggest advantage is that they achieve zero carbon emissions, producing only water. They also have relatively low requirements for hydrogen purity. This technology uses a mature internal combustion engine structure, has low modification costs, and is a practical transitional solution for ships to move towards a clean energy era. It is suitable for power upgrades of various types of ships.

[0003] Hydrogen burns rapidly and has a high peak pressure. Ships are constantly subjected to wave impacts, which can easily lead to abnormal shocks and vibrations in the engine block. Over time, this can cause metal fatigue, loosening of connectors, and even cylinder block cracks, resulting in high-pressure hydrogen leakage. Hydrogen is highly flammable and explosive. Once it accumulates, even a tiny ignition source can cause a deflagration accident, endangering the safety of the entire ship. To address these issues, we provide a marine hydrogen internal combustion engine body reinforcement device. Utility Model Content

[0027] This utility model provides a device for reinforcing the body of a marine hydrogen internal combustion engine.

[0028] Example 1:

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a mounting box 1, which integrates a hydrogen sensor and an alarm device. When the hydrogen sensor detects that the hydrogen concentration in the mounting box 1 reaches a threshold, the hydrogen sensor will immediately send an activation command to the alarm device to trigger an alarm. The hydrogen sensor and the alarm device are existing technologies and are not the main innovation of this application, so they are not shown in the figure and will not be described in detail in this application.

[0030] The interior of the mounting box 1 is equipped with a reinforcing mechanism 2, which includes a reinforcing rib 201 and a body shell 202. The outer surface of the reinforcing rib 201 is slidably connected to the mounting box 1, and the outer surface of the body shell 202 is fixedly connected to the reinforcing rib 201. The reinforcing rib 201 can enhance the structural strength of the body shell 202, effectively improve vibration resistance, prevent hydrogen leakage and deflagration, and ensure ship safety.

[0031] A limiting ring 203 is fixedly connected to the bottom surface of the reinforcing rib 201. A driven plate 204 is rotatably connected to the outer surface of the limiting ring 203. A limiting post 205 is sleeved inside the driven plate 204. One end of the limiting post 205 is fixedly connected to the mounting box 1. A limiting block 206 is rotatably connected to the inner wall of the driven plate 204. Through the setting of the limiting ring 203 and the limiting post 205, the driven plate 204 is effectively limited, making the driven plate 204 more stable during movement.

[0032] A damping rod 207 is fixedly connected to the inner wall of the mounting box 1. The telescopic end of the damping rod 207 is fixedly connected to the reinforcing rib frame 201. A buffer spring 208 is sleeved on the outer surface of the damping rod 207. The two ends of the buffer spring 208 are fixedly connected to the mounting box 1 and the reinforcing rib frame 201 respectively. Through the synergistic effect of the damping rod 207 and the buffer spring 208, the vibration force on the reinforcing rib frame 201 can be effectively damped and reduced.

[0033] Example 2:

[0034] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting block 206 is internally fitted with a linkage frame 209. One end of the linkage frame 209 is fixedly connected to a transmission rod 210. The outer surface of the transmission rod 210 is rotatably connected to the mounting box 1. Through the setting of the mounting box 1, the transmission rod 210 is effectively limited, so that the driven plate 204 can effectively drive the transmission rod 210 to rotate synchronously when moving in multiple modes.

[0035] A sprocket 211 is fixedly connected to the end of the transmission rod 210 away from the linkage frame 209. A chain 212 is connected to the outer surface of the sprocket 211, and a sprocket 213 is connected to the outer surface of the chain 212. By driving the sprocket 211 to rotate and in conjunction with the chain 212, the sprocket 213 can be driven to rotate synchronously.

[0036] A driven screw 214 is fixedly connected to the outer surface of sprocket 213. The outer surface of the driven screw 214 is rotatably connected to the mounting box 1. A bonding plate 215 is threadedly connected to the outer surface of the driven screw 214. A limiting slide rod 216 is fixedly connected to the outer surface of the bonding plate 215. The outer surface of the limiting slide rod 216 is slidably connected to the mounting box 1. The limiting slide rod 216 effectively limits the bonding plate 215, making the bonding plate 215 more stable when moving horizontally. A soft friction strip is fixedly installed on the outer surface of the bonding plate 215. When the friction strip contacts the reinforcing rib 201, it can effectively provide friction force for the reinforcing rib 201 when it moves vertically.

[0037] Example 3:

[0038] Please refer to it again. Figure 2 and Figure 3 The installation box 1 is equipped with a cooling mechanism 3, which includes a cooling pipe 301. The outer surface of the cooling pipe 301 is fixedly connected to the outer shell 202 of the machine body. Both ends of the cooling pipe 301 pass through the reinforcing rib 201 and are fixedly connected to the reinforcing rib 201. The cooling pipe 301 and the outer shell 202 of the machine body are directly fixed by bolts through a U-shaped ring, so that the cooling pipe 301 can always be in contact with the outer shell 202 of the machine body to ensure cooling efficiency.

[0039] A pump body 302 and a cooling device 303 are fixedly connected to the top surface of the reinforcing rib frame 201. The output end of the pump body 302 is fixedly connected to the cooling pipe 301, and the input end of the cooling device 303 is fixedly connected to the cooling pipe 301. A connecting pipe 304 is fixedly connected between the input end of the pump body 302 and the output end of the cooling device 303. By turning on the pump body 302 and the cooling device 303, the coolant in the cooling pipe 301 can continuously circulate and cool within the cooling pipe 301, so that the cooling pipe 301 can continuously cool the outer shell 202 of the machine body.

[0040] The pump body 302 and cooling device 303 in this application are common electrical devices in the prior art, and this application will not elaborate on their models and internal structures.

[0041] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0042] In use, this invention firstly enhances the structural strength of the outer shell 202 through the reinforcing rib 201, effectively improving vibration resistance, preventing hydrogen leakage and deflagration, and ensuring ship safety. When the outer shell 202 vibrates due to its own vibration or that of the ship, the damping rods 207 and buffer springs 208 on the upper and lower sides of the reinforcing rib 201 effectively dampen and reduce the vibration force. When the vibration force is strong enough to cause significant swaying and floating of the reinforcing rib 201 on the surface of the outer shell 202, it can drive the driven disc 204 to simultaneously sway vertically along the length of the limiting post 205. During the swaying process of the driven disc 204, the limiting block 206 and the transmission rod 210 limit the driven disc 204 to oscillate back and forth around the limiting post 205 while swaying vertically. Thus, the multi-mode movement of the driven disc 204 drives the sprocket 211 on one end of the transmission rod 210 to rotate. The rotation of sprocket 211, combined with the transmission of chain 212, effectively drives the driven screw 214 on the surface of sprocket 213 to rotate. The rotation of driven screw 214, combined with the limiting slide 216, drives the bonding plate 215 to approach and adhere tightly to the side of the reinforcing rib frame 201. The tight adhesion of the bonding plate 215 can enhance the friction of the reinforcing rib frame 201 during vertical movement, effectively preventing the reinforcing rib frame 201 from shaking violently. This design greatly improves the safety and reliability of the device. Secondly, when the outer shell 202 of the machine body is hot, the pump body 302 and the cooling equipment 303 can be started to continuously cool the cooling pipe 301. The cooled cooling pipe 301 can cool the outer shell 202 of the machine body, effectively preventing the outer shell 202 from generating thermal stress or material aging due to high temperature, thereby improving the operational stability and durability, and greatly extending the service life of the whole machine.
