[0045] With the above scheme: by setting the ventilation pipe 604, when the noise reduction rubber block 601 is extruded and deformed by the vibration force, the gas inside will be introduced into the lubricating oil storage cylinder 503 through the ventilation pipe 604, so that the air pressure at the rear end of the lubricating oil storage cylinder 503 is increased, so that the driving piston block 504 pushes the lubricating oil in the lubricating oil storage cylinder 503 into the lubricating noise reduction cavity 501, so as to reduce the friction between the ventilation pipe 2 and the ventilation fan blade 3 in the future.

[0046] As shown in Figure 4 , the ventilation pipe 2 is provided with a shielding assembly 7 between the lubricating oil storage cylinder 503 and the lubricating noise reduction cavity 501, and the shielding assembly 7 comprises a first hydraulic cavity 701, a hydraulic piston rod 702 and a shielding circular plate 703.

[0047] The first hydraulic cavity 701 is opened in the ventilation pipe 2, and is located between the lubricating oil storage cylinder 503 and the lubricating noise reduction cavity 501. The hydraulic piston rod 702 is movably installed in the inner cavity of the first hydraulic cavity 701. The shielding circular plate 703 is arranged on the outside of the hydraulic piston rod 702.

[0048] With the above scheme: by setting the shielding circular plate 703, when the hydraulic oil in the inner cavity of the first hydraulic cavity 701 is pumped out, the hydraulic piston rod 702 drives the shielding circular plate 703 to move to one side, so that the blocking effect between the lubricating oil storage cylinder 503 and the lubricating noise reduction cavity 501 is removed.

[0049] As shown in Figure 4 and Figure 5 , the ventilation pipe 2 is provided with a power assembly 8 in front of the lubricating noise reduction cavity 501, and the power assembly 8 comprises a second hydraulic cavity 801, a power piston rod 802, a reset spring 803 and an oil channel 804.

The second hydraulic cavity 801 is connected with the inner cavity of the first hydraulic cavity 701 through the power piston rod 802.

[0051] With the above scheme: by setting the reset spring 803, when the elastic force of the reset spring 803 is released, the power piston rod 802 can be smoothly pushed to move to one side as a whole, so that the 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 pumped out through the oil channel 804.

[0052] As Figure 7 and Figure 8 shown, the inside of the ship cabin shell 1 and the ventilation duct 2 is provided with a heat transfer assembly 9, which includes a first spiral pipe 901, a second spiral pipe 902, a circular water tank 903 and a drive water wheel 904;

[0053] The first spiral pipe 901 is arranged inside the ventilation duct 2 and located outside the lubricating oil storage cylinder 503, the second spiral pipe 902 is arranged inside the ship cabin shell 1 and located outside the noise reduction rubber block 601, the circular water tank 903 is fixedly connected to the front and rear ends of the inside of the first spiral pipe 901 and the second spiral pipe 902, and the drive water wheel 904 is movably sleeved inside the circular water tank 903.

[0054] The above scheme is adopted: by arranging the drive water wheel 904, when the drive 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] As Figure 7 shown, the front and rear ends of the first spiral pipe 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 pipe 902 are connected to the other side of the inner end of the circular water tank 903.

[0056] The above scheme is adopted: by arranging the circular water tank 903, when the drive water wheel 904 rotates inside the inner wall of the circular water tank 903 to drive the water flow, the water inside the first spiral pipe 901 can enter the inside of the front end of the circular water tank 903 through the front end of the first spiral pipe 901, then enter the inside from the front end of the second spiral pipe 902, and then flow to the inside of the rear end of the circular water tank 903 through the rear end of the second spiral pipe 902, and finally be guided back to the inside of the first spiral pipe 901 through the rear end of the first spiral pipe 901, realizing the circulation of the water flow inside the first spiral pipe 901 and the second spiral pipe 902.

[0057] As Figures 6 to 8 shown, the outside of the drive water wheel 904 is provided with a linkage assembly 10, which 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 drive water wheel 904, the second rotating plate 103 is fixedly sleeved on the front and rear middle parts of the ventilation fan blade 3, and the linkage plate 102 is movably sleeved between the first rotating plate 101 and the second rotating plate 103.

[0059] The above scheme is adopted: by arranging the linkage plate 102, when the ventilation fan blade 3 rotates, the second rotating plate 103 can be driven to rotate, so as to smoothly drive the first rotating plate 101 and the drive water wheel 904 as a whole to rotate.

[0060] As Figure 3 shown, the rear end of the lubricating oil storage cylinder 503 is fixedly communicated with the delivery valve pipe 11.

[0061] With the above scheme: by setting the delivery valve pipe 11, the operator can connect the pipeline through the delivery valve pipe 11 position, and continuously introduce the external lubricating oil into the interior for replenishment.

[0062] The working principle and use process of the application are as follows:

[0063] First, through the elastic force of the reset spring 803, the power piston rod 802 can be pushed to move to one side as a whole, at this time, the negative pressure is generated on one side of the second hydraulic cavity 801, and the hydraulic oil in the first hydraulic cavity 701 is drawn away through the oil channel 804, so as to drive the hydraulic piston rod 702 to move the shielding circular plate 703 to one side as a whole, until the shielding circular plate 703 removes the plugging effect between the lubricating and noise reduction cavity 501 and the lubricating oil storage cylinder 503, and when the sea wind drives the ventilation fan blade 3 to rotate in the inner wall of the ventilation pipeline 2, the ventilation pipeline 2 is pressed to drive the noise reduction rubber block 601 to move, so that part of the gas in the noise reduction rubber block 601 is pushed to be introduced into the inner cavity of the lubricating oil storage cylinder 503 through the air duct 604, and then the gas drives the driving piston block 504 to drive the lubricating oil in the lubricating oil storage cylinder 503 to be pushed and introduced into the inner cavity of the lubricating and noise reduction cavity 501, so that the lubricating oil in the inner cavity of the lubricating and noise reduction cavity 501 reduces the friction force removed by the ventilation pipeline 2 and the ventilation fan blade 3, thereby reducing the noise generated by the rotation of the ventilation fan blade 3.

[0064] When the lubricating and noise reduction cavity 501 is full of lubricating oil, the power piston rod 802 is pressed and moved to the other side, so that the hydraulic oil in the second hydraulic cavity 801 is pushed and guided back to the first hydraulic cavity 701 through the oil channel 804, and the hydraulic piston rod 702 and the shielding circular plate 703 are moved to reset to block the lubricating and noise reduction cavity 501 and the lubricating oil storage cylinder 503, at the same time, when the damping spring 603 is released, the noise reduction rubber block 601 is restored as a whole, so that the inner cavity of the noise reduction rubber block 601 generates negative pressure, the gas on one side of the lubricating oil storage cylinder 503 is drawn away through the air duct 604, and the driving piston block 504 is reset, finally, through the vibration and the elastic reset of the damping spring 603, the driving piston block 504 is moved back and forth to press and push the lubricating oil in the lubricating oil storage cylinder 503, and heat is generated.

[0065] After the whole rotation of the ventilation fan blade 3, the second rotating plate 103 at the front and back 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 as to make the driving water wheel 904 rotate to drive the water flow in the circular water tank 903 at the front and back ends, and then the water flow is guided from the front end of the circular water tank 903 to the front end of the second spiral pipe 902 through the first spiral pipe 901 at the front end, and then guided from the rear end of the second spiral pipe 902 to the rear end of the circular water tank 903, and then guided to the rear end of the first spiral pipe 901, realizing the back and forth circulation of the inner cavities of the first spiral pipe 901 and the second spiral pipe 902, and when the lubricating oil in the lubricating oil storage cylinder 503 generates heat, the heat can be absorbed by the water flow in the first spiral pipe 901, and then transmitted to the second spiral pipe 902, and finally the heat of the second spiral pipe 902 can assist the noise reduction rubber block 601 and the damping spring 603 to restore to the original state.
