[0024] The above technical solution is to set up a lubricating oil storage cylinder, a noise reduction rubber block and a power component. The power component can drive the shielding component to release the blockage between the lubricating oil storage cylinder and the lubricating noise reduction chamber. After that, when the ventilation fan blades rotate as a whole, the ventilation duct as a whole will vibrate, thereby squeezing the noise reduction rubber block, so that part of the gas in the noise reduction rubber block enters the lubricating oil storage cylinder through the ventilation duct, and can push the driving piston block to drive the lubricating oil in the lubricating oil storage cylinder into the lubricating noise reduction chamber, so as to smoothly lubricate the part of the ventilation fan blades that contacts the ventilation duct, thereby reducing friction, and then achieving the purpose of noise reduction, and smoothly improving the comfort of passengers.
[0025] The present invention provides a noise reduction rubber block, a telescopic rod and a vibration-damping spring. The design of the noise reduction rubber block can reduce the noise generated by the vibration to which the ventilation duct as a whole is subjected, while the elastic design of the vibration-damping spring can buffer the vibration force generated by the rotation of the ventilation fan blades on the ventilation duct. At the same time, the telescopic nature of the telescopic rod can assist the vibration-damping spring in limiting buffering, thereby achieving a good vibration reduction and noise reduction purpose for the ventilation duct as a whole. When the air pressure in the noise reduction rubber block changes, the driving piston block can be driven through the ventilation duct to continuously push the lubricating oil in the lubricating oil storage cylinder to be introduced into the lubricating noise reduction chamber, so that the lubricating oil is constantly filled inside the lubricating noise reduction chamber for noise reduction treatment.

When the ventilation fan blades rotate as a whole, the second rotating plates at the front and rear ends can be driven to rotate. At this time, the linkage plate will link the first rotating plate and the driving water wheel to rotate synchronously as a whole, so that the driving water wheel drives the water inside the circular water tanks at the front and rear ends to flow, and then the water flows back and forth in the inner cavities of the first spiral tube and the second spiral tube. Then, the heat generated by the lubricating oil in the lubricating oil storage cylinder being squeezed back and forth by the driving piston block will be transferred to the second spiral tube through the first spiral tube. At this time, the heat inside the second spiral tube will assist the noise reduction rubber block and the vibration reduction spring to recover as a whole, thereby maintaining the elastic characteristics of the noise reduction rubber block and the vibration reduction spring.

[0040] By adopting the above solution, the limiting ring 4 is designed so that the ventilation fan blade 3 can be integrally sleeved on the inner side of the ventilation duct 2, and the integral rotational movement of the ventilation fan blade 3 can be limited.
[0041] like Figure 2 As shown, the vibration reduction assembly 6 includes a noise reduction rubber block 601, a telescopic rod 602, a vibration reduction spring 603 and a ventilation pipe 604;

The second hydraulic chamber 801 is connected to the inner cavity of the first hydraulic chamber 701 through the power piston rod 802.
[0051] The above scheme is adopted: by providing a return spring 803, when the elastic force of the return spring 803 is released, the power piston rod 802 can be smoothly pushed to move to one side as a whole, so that negative pressure is generated in the inner cavity of the second hydraulic cavity 801 and the hydraulic oil in the inner cavity of the first hydraulic cavity 701 is smoothly drawn away through the oil groove 804.
[0052] like Figure 7 and Figure 8 As shown, a heat transfer component 9 is arranged inside the ship cabin shell 1 and the ventilation duct 2, and the heat transfer component 9 includes a first spiral tube 901, a second spiral tube 902, a circular water tank 903 and a driving water wheel 904;

[0054] The above solution is adopted: by providing a driving water wheel 904, when the driving water wheel 904 is driven to rotate as a whole, the water inside the circular water tank 903 can be driven to flow inside.
[0055] like Figure 7 As shown, the front and rear ends of the first spiral tube 901 are connected to one side of the inner end of the circular water tank 903 , and the front and rear ends of the second spiral tube 902 are connected to the other side of the inner end of the circular water tank 903 .
[0056] The above scheme is adopted: by providing a circular water tank 903, when the driving water wheel 904 drives the water to flow when rotating on the inner wall of the circular water tank 903, the water inside the first spiral tube 901 can enter the interior of the front circular water tank 903 through the front end of the first spiral tube 901, and then enter the interior from the front end of the second spiral tube 902, and then flow to the interior of the circular water tank 903 at the rear end through the rear end of the second spiral tube 902, and finally be guided back to the first spiral tube 901 through the rear end of the first spiral tube 901, so that the water flow can circulate back and forth inside the first spiral tube 901 and the second spiral tube 902.
[0057] like Figures 6 to 8 As shown, a linkage assembly 10 is disposed on the outer side of the driving water wheel 904, and the linkage assembly 10 includes a first rotating plate 101, a linkage plate 102 and a second rotating plate 103;
[0058] The first rotating plate 101 is fixedly sleeved on the outer end surface of the driving water wheel 904 , the second rotating plate 103 is fixedly sleeved on the middle of the front and rear of the ventilation fan blades 3 , and the linkage plate 102 is movably sleeved between the first rotating plate 101 and the second rotating plate 103 .
[0059] By adopting the above solution, the linkage plate 102 is provided, and when the ventilation fan blades 3 rotate, the second rotating plate 103 can be driven to rotate, so that the first rotating plate 101 and the driving water wheel 904 can be smoothly driven to rotate as a whole through the second rotating plate 103.
[0060] like Figure 3 As shown, the rear end of the inner side of the lubricating oil storage cylinder 503 is fixedly connected to the delivery valve pipe 11 .
[0061] By adopting the above solution, the delivery valve pipe 11 is provided, and the operator can connect the pipeline through the delivery valve pipe 11 and continuously introduce the external lubricating oil into the interior for replenishment.
[0062] The working principle and use process of the present invention:
[0063] First, the elastic force of the return spring 803 can push the power piston rod 802 to move to one side as a whole. At this time, negative pressure will be generated on one side of the inner cavity of the second hydraulic chamber 801, and the hydraulic oil in the inner cavity of the first hydraulic chamber 701 will be pumped out through the oil groove 804, so as to drive the hydraulic piston rod 702 to drive the shielding circular plate 703 to move to one side as a whole, until the shielding circular plate 703 releases the blocking effect between the lubrication and noise reduction chamber 501 and the lubricating oil storage cylinder 503, and when the sea breeze pushes the ventilation fan blades 3 to rotate on the inner wall of the ventilation duct 2 When the noise reduction rubber block 601 is pushed by the vibration force, the ventilation duct 2 will be subjected to the vibration force, so that part of the gas in the noise reduction rubber block 601 is pushed from the ventilation duct 604 into the inner cavity of the lubricating oil storage cylinder 503, and then the gas will push the driving piston block 504 to drive the lubricating oil in the lubricating oil storage cylinder 503 to be pushed into the inner cavity of the lubricating noise reduction chamber 501, and finally the lubricating oil in the inner cavity of the lubricating noise reduction chamber 501 reduces the friction between the ventilation duct 2 and the ventilation fan blades 3, thereby reducing the noise generated by the rotation of the ventilation fan blades 3.
[0064] Then, when the lubricating oil in the lubricating and noise reduction chamber 501 is full, it will squeeze and push the power piston rod 802 to move to the other side, so that the hydraulic oil in the inner cavity of the second hydraulic chamber 801 is pushed back to the first hydraulic chamber 701 through the oil groove 804, and push the hydraulic piston rod 702 and the shielding circular plate 703 to move and reset to seal the lubricating and noise reduction chamber 501 and the lubricating oil storage cylinder 503. At the same time, when the elastic force of the vibration reduction spring 603 is released, the noise reduction rubber block 601 is restored as a whole, which will cause negative pressure in the inner cavity of the noise reduction rubber block 601, and the gas on one side of the lubricating oil storage cylinder 503 will be extracted through the ventilation pipe 604, which will drive the driving piston block 504 to reset, and finally reset through vibration and the elastic force of the vibration reduction spring 603, which can drive the driving piston block 504 to move back and forth to squeeze and push the lubricating oil in the lubricating oil storage cylinder 503 to generate heat.
[0065] Afterwards, when the ventilation fan blades 3 rotate as a whole, the second rotating plate 103 at the front and rear ends can be driven to rotate. At this time, the first rotating plate 101 and the driving water wheel 904 can be driven to rotate as a whole through the linkage plate 102, so that the driving water wheel 904 rotates to drive the water inside the circular water tanks 903 at the front and rear ends to flow, and then the water flows through the front end of the first spiral tube 901 from the front circular water tank 903 to the front end of the second spiral tube 902, and then from the rear end of the second spiral tube 902 to the inside of the rear circular water tank 903 to the rear end of the first spiral tube 901, so as to realize the back and forth circulation of the inner cavities of the first spiral tube 901 and the second spiral tube 902. When the lubricating oil in the lubricating oil storage cylinder 503 generates heat, the heat will be absorbed by the water flow in the first spiral tube 901, and then transferred to the second spiral tube 902, and finally the heat of the second spiral tube 902 is used to assist the noise reduction rubber block 601 and the vibration reduction spring 603 to return to their original state as a whole.
