[0028] In some examples, the top wire fixing buckle 51 is composed of three groups of buckle bodies 511 , and two adjacent groups of buckle bodies 511 are fixedly connected by fixing bolts 512 .

[0029] In some examples, the bottom steel wire fixing buckle 52 includes a bottom plate 521 and a fixing buckle body 522, and the bottom steel wire fixing buckle 52, the buckle body 511 and the steel wire rope 53 are each provided in three groups, one end of the steel wire rope 53 is fixed to the fixing buckle body 522 of the bottom steel wire fixing buckle 52, and the other end of the steel wire rope 53 is fixed to the buckle body 511.

[0031] In some examples, a first bolt hole 611 is formed on the fixing ear plate 61 , and a second bolt hole 621 is formed on the locking plate 62 .

[0032] Among them, before sailing, the smoke exhaust pipe body 11 needs to be laid down, and after the smoke exhaust pipe body 11 is laid down, it needs to be fixed to prevent the smoke exhaust pipe body 11 from moving with the shaking of the ship.

When the newly added generator needs to be started when docking or mooring for medical purposes, the smoke exhaust pipe body 11 needs to be erected at this time. During navigation, the newly added generator does not need to work. At this time, the smoke exhaust pipe body 11 can be laid down. On the one hand, it can reduce the height requirement for the medical ship to pass through. On the other hand, in severe sea conditions, it can avoid damage to the smoke exhaust pipe body 11, play a role in safety protection, and solve the problem that the medical ship does not meet the height requirement for navigation when passing through some river bridges during navigation.

[0034] Embodiment 2: Based on Example 1, this example introduces the specific structure of a driving component 3 and a hand-operated pump station 4 in a reversible smoke exhaust pipe. The hand-operated pump station 4 includes an oil tank 41, a liquid level meter 42 is arranged on the outside of the oil tank 41, and a manual pump 43, an air filter 44, a valve group 45 and a pressure gauge 46 are arranged on the upper end of the oil tank 41.

[0035] Among them, the oil tank 41 is used to store the hydraulic oil required by the hydraulic system, and the liquid level gauge 42 realizes long-distance indication, detection and control of the liquid level. When the hydraulic system is working, the oil level in the oil tank 41 rises or falls from time to time. When rising, the air is discharged from the inside to the outside, and when falling, the air is sucked in from the outside to the inside. In order to purify the oil inside the oil tank 41, an air filter 44 is vertically installed on the cover plate of the oil tank 41 to filter the inhaled air. The air filter 44 can maintain the pressure in the oil tank 41 and the atmospheric pressure in balance to avoid cavitation in the pump. When in use, you only need to manually shake the handle of the manual pump 43 back and forth, and the pressure gauge 46 is connected to the pressure pipeline of the hydraulic system.

[0036] In some examples, universal wheels 47 are fixed at the corners of the bottom of the hand-cranked pump station 4 , and the provision of the universal wheels 47 facilitates the movement of the hand-cranked pump station 4 .

[0037] In some examples, the hydraulic cylinder 31 is provided with quick inlet and outlet interfaces, the hose 313 includes a quick connector 314, a lower fixed end 311 is provided at one end of the hydraulic cylinder 31, and a telescopic end 312 is provided at the other end of the hydraulic cylinder 31, the lower fixed end 311 is connected to the bottom support 33 of the cylinder, and the telescopic end 312 is connected to the top support 32 of the cylinder, and the bottom support 33 of the cylinder includes a vertical plate 331, a bracket 332 is welded and fixed on the outer surface of the vertical plate 331, and a hole sleeve 333 and a safety pin 334 are provided on the vertical plate 331.

[0038] Working principle of driving component 3: A top support 32 of an oil cylinder is welded on the hinge assembly mechanism 2 at the root of the smoke exhaust pipe body 11, and a bottom support 33 of an oil cylinder is welded on the chimney top plate 1 near the smoke exhaust pipe. The hydraulic cylinder 31 is fixed between the two supports. A quick inlet and outlet interface is provided on the hydraulic cylinder 31, which is connected to the hydraulic hand-cranked pump station 4 through a hose 313. A driving hydraulic cylinder 31 is designed at the root of the smoke exhaust pipe body 11, and pressure is provided to the hydraulic cylinder 31 through an external hydraulic hand-cranked pump station 4. The smoke exhaust pipe body 11 is driven by the hydraulic cylinder 31, so that the smoke exhaust pipe body 11 can be collapsed and erected.

[0039] Installation points: When installing the hinge assembly mechanism 2, it is necessary to assemble the upper hinge component 21, the lower hinge component 22 and the rotating pin 23 of the hinge assembly mechanism 2 into one body, and then weld the entire body to the smoke exhaust pipe main body 11. This can ensure the concentricity of the pin shaft hole after the upper and lower parts of the hinge are installed, and ensure that the pin shaft can be accurately disassembled and assembled later. When installing the hydraulic cylinder 31, it is necessary to pay attention to first installing the cylinder bottom support 33, and then connect and fix the lower fixed end 311 of the hydraulic cylinder 31 and the cylinder bottom support 33, and then fully open the hydraulic cylinder 31, and then install the cylinder top support 32 on the telescopic end 312 of the upper end of the hydraulic cylinder 31, and then put the cylinder top support 32 against the upright smoke exhaust pipe main body 11, and weld the cylinder top support 32 and the smoke exhaust pipe main body 11 together. This can ensure that when the cylinder is fully opened, the smoke exhaust pipe main body 11 is in an upright state, which ensures the installation accuracy of the smoke exhaust pipe main body 11 after retracting.

[0040] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
