Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Depend on Figure 1-Figure 5 It is given that the ventilation structure of the seawater pump room includes a ventilation pipe body 1, a mounting cover 2, a closing mechanism 3 and a driving mechanism 4. The ventilation pipe body 1 is installed in the seawater pump room wall 12 and fixed to the inner wall of the seawater pump room wall 12 by bolts. The ventilation pipe body 1 is connected to the mounting cover 2 on one side, and a closing mechanism 3 is arranged inside the mounting cover 2. The closing mechanism 3 includes two closing plates 31 hinged at the inner wall of the mounting cover 2, and the closing plate 31 is located at the air inlet position of the mounting cover 2. One side of the closing plate 31 is rotatably connected to a driving rod 32, and the other end of the driving rod 32 is rotatably connected to a moving block 33, and the moving block 33 is threadedly sleeved on the outside of a screw rod 34, and the screw rod 34 is rotatably connected to the inside of a protective shell 35. One side of the protective shell 35 is connected to a driving mechanism 4, and the driving mechanism 4 is used to drive the two screw rods 34 to rotate, and the protective shell 35 is fixed on both sides of the inner wall of the mounting cover 2.

[0024] As mentioned above, by setting the closing mechanism 3, when the outside humidity is high or the water vapor is high on rainy days, the screw rod 34 inside the protective shell 35 is rotated through the driving mechanism 4, so that the moving block 33 moves, and then the driving rod 32 is rotated and drives the closing plate 31 to rotate. Finally, the two closing plates 31 are turned to a vertical state to block the air inlet of the mounting cover 2, thereby preventing water vapor from entering the seawater pump room through the ventilation pipe body 1, thereby effectively protecting electronic equipment and wires from moisture corrosion. When ventilation and heat dissipation are needed, the screw rod 34 can be rotated in the opposite direction, which is very convenient.

[0025] The driving mechanism 4 includes a bevel gear A41 rotatably connected to one side of the protective shell 35 , the bevel gear A41 docks with the screw rod 34 and meshes with a bevel gear B42 , the bevel gear B42 is fixed to the outside of a rotating rod 43 , and the rotating rod 43 is driven to rotate by a motor 44 fixed to one side of the mounting cover 2 .

[0026] As mentioned above, by setting the driving mechanism 4, when it is necessary to drive the screw rod 34 to rotate, the motor 44 is started to rotate the rotating rod 43, and then the bevel gear B42 is rotated. The bevel gear B42 rotates the bevel gear A41 through engagement, so that the screw rod 34 can be driven to rotate and perform the closing operation very conveniently. It is noted that the motor 44 can be manually controlled through a wireless connection, and can also be connected to an intelligent control system. For example, it can be started by a sensor that detects rain to perform automatic closing. This is a prior art and is very easy to use.

[0027] A protective shell 45 is connected to the side of the protective shell 35 and the inner wall of the mounting cover 2. The protective shell 45 covers the bevel gear B42 and the bevel gear A41 inside. A pipe sleeve 46 is connected between the protective shells 45 on both sides of the inner wall of the mounting cover 2, and the pipe sleeve 46 surrounds the rotating rod 43 inside.

[0028] As described above, the protective shell 45 and the sleeve 46 can effectively protect the bevel gear B42, the bevel gear A41 and the rotating rod 43 to prevent moisture or dust from sticking to them and causing corrosion or affecting their operation.

[0029] A protective plate 5 is nailed to the air inlet of the mounting cover 2, and rectangular openings are arranged and designed on the protective plate 5. Openings are set at the positions of the screw rods 34 on both sides of the mounting cover 2, and sealing plates 9 are hinged at the openings. A rain shield 10 is welded to the mounting cover 2 above the sealing plate 9. A splicing plate 7 is fixed to the butt end of the ventilation pipe body 1 and the mounting cover 2. The splicing plates 7 are fixed together with bolts, and the outer walls of the two splicing plates 7 are bonded with waterproof tapes 8. The two splicing plates 7 are each provided with a notch, and the notches of the two splicing plates 7 are engaged with filter screens 6.

[0030] As mentioned above, in the structural optimization design of the installation cover 2, the protective plate 5 can prevent some seabirds from entering the interior, and the splicing plate 7 is easy to assemble. At the same time, the filter screen 6 can be placed in the groove of the splicing plate 7 on the ventilation pipe body 1 during installation. Then, after the assembly is completed, the two splicing plates 7 complete the fixation of the filter screen 6, so there is no need to install it with screws. The filter screen 6 can further filter dust and ensure the indoor environmental quality. At the same time, the waterproof tape 8 can enhance the sealing. Finally, the sealing plate 9 can be opened to maintain the screw rod 34, and the rain shield 10 can play a rain shielding role to prevent the hinge shaft of the sealing plate 9 or the motor 44 from being damaged by rain erosion.

[0031] Working principle: First, install the ventilation pipe body 1 into the wall body 12, and then the filter screen 6 can be placed in the groove of the splicing plate 7 on the ventilation pipe body 1 during installation, and then assembled through the splicing plate 7. After installation, the waterproof tape 8 is tied to the splicing of the splicing plate 7 to achieve sealing. During daily work, the filter screen 6 and the protective plate 5 can play a protective filtering role. On rainy days when the outside humidity is large or there is a lot of water vapor, the rotating rod 43 is rotated by starting the motor 44, and then the bevel gear B42 is rotated, and the bevel gear B42 is meshed to make The bevel gear A41 rotates, thereby conveniently driving the screw rod 34 to rotate, causing the moving block 33 to move, and then causing the driving rod 32 to rotate and drive the closing plate 31 to rotate. Finally, the two closing plates 31 are rotated to a vertical state to block the air inlet of the mounting cover 2, thereby preventing water vapor from entering the seawater pump room through the ventilation pipe body 1. When it is necessary to add lubricating oil to the screw rod 34 or to perform maintenance, the sealing plate 9 can be opened, and the rain shield 10 can play a rain shielding role to prevent the hinge shaft of the sealing plate 9 or the motor 44 from being damaged by rain erosion.
