[0054] In one embodiment, the other end of the air intake and exhaust box body 1 is sealed to the side wall plate via an O-ring 3 .

[0056] The gaps of the exhaust cover of the ship's outer plate stealth pneumatic intake and exhaust device are uniform and do not deflect.

[0057] In one embodiment, the gas cylinder 4 is supplied with gas from a gas bottle.

[0058] In this embodiment, a specific air supply method for the cylinder 4 is provided.

[0059] In one embodiment, the cylinder 4 has a self-locking function. When the stealth air intake and exhaust cover 2 is opened or closed by high-pressure air, if the high-pressure air in the cylinder 4 is cut off, the stealth air intake and exhaust cover 2 can maintain the current state.

[0060] In this embodiment, a specific implementation method of self-locking is provided. The cylinder is connected to the air intake and exhaust box and ventilated, which can control the opening and closing of the pneumatic stealth air intake and exhaust cover and has a self-locking function. When the stealth air intake and exhaust cover is opened or closed by high-pressure air, if the high-pressure air is cut off, the current state can be maintained.

[0061] In one embodiment, when there is no gas in the gas cylinder, the stealth air intake and exhaust cover 2 can be opened or closed by the manual operating device 5;

[0062] The manual operating device 5 and the air cylinder 4 are both arranged outside the box body 1 .

[0063] In this embodiment, a specific implementation method is provided in the gas cylinder without gas. As mentioned above, the pneumatic stealth air intake and exhaust cover has the function of manual opening and closing when there is no gas source; the opening and closing signal can be transmitted to the remote through the limit switch.

[0064] In one embodiment, the ship outer plate stealth pneumatic air intake and exhaust device is used for bow ventilation.

[0065] In one embodiment, the ship outer plate stealth pneumatic air intake and exhaust device can withstand the impact of waves, and the continuous impact force should be no less than 300kPa.

[0066] In this embodiment, a specific implementation method of an air intake and exhaust device for bow ventilation is provided, which can withstand the impact of waves and the continuous impact force should be no less than 300 kPa.

[0067] In one embodiment, a water drain port and a plurality of air inlet and outlet ports are provided.

[0068] The present invention adopts the external structure of the pneumatic and manual dual control system, and compared with the prior art, its beneficial effects are as follows:

[0069] 1. The stealth air intake and exhaust cover is integrated with the device box. During normal navigation, the stealth air intake and exhaust cover located at the bow is in the open state. After the seawater enters the device box through the stealth air intake and exhaust cover, the box collects the seawater and discharges it reasonably through the drain port, reducing the corrosive damage of seawater to the equipment.

[0070] 2. Only stealth air inlet and exhaust covers, transmission shafts and bushings are installed inside the box. Sealing rings are installed at bushings. Manual and pneumatic operation devices of stealth air inlet and exhaust covers are installed outside the box to prevent seawater corrosion. Multiple air inlet and exhaust ports can be installed on the device box to facilitate the connection of multiple air ducts.

[0071] 3. The surface ship radar wave stealth design is adopted. When the stealth intake and exhaust covers are closed, the gaps between the stealth intake and exhaust covers and the hull are uniform, and the stealth intake and exhaust covers are flush with the hull; the stealth intake and exhaust covers can withstand the impact of waves without displacement or deflection.

[0072] 4. The operating mechanism adopts manual + pneumatic dual control design. Both manual and pneumatic actuators are installed outside the device box. The device box can effectively isolate seawater splashes, improve anti-corrosion performance, and facilitate connection of gas and circuits, which is convenient for later maintenance.

[0073] 5. The manual and pneumatic actuators can be led to convenient operating positions through connecting rods, which is convenient for crew members to operate.

[0074] 6. The cylinder has a self-locking function. When the stealth air intake and exhaust cover is opened or closed by high-pressure air, if the high-pressure air is cut off, the current state can be maintained; when there is no air in the air circuit, the stealth air intake and exhaust cover can be opened or closed by a manual mechanism.

[0075] Based on the above structure, Figure 1 , 2 As shown, the ship's stealth outer panel pneumatic air intake and exhaust device includes a device box, a stealth intake and exhaust cover, an O-ring, a cylinder, a manual operating device, a driving shaft, an intake and exhaust box, etc.

[0076] Turn on the air intake and exhaust box switch, and the cylinder 4 is connected to the gas cylinder. After the gas cylinder is passed through high-pressure air, the cylinder 4 enters the working state. Under the control of the air intake and exhaust box signal, the cylinder 4 opens or closes the stealth air intake and exhaust cover 2 through the transmission of force between the cylinder 4 and the driving shaft 6. When the stealth air intake and exhaust cover 2 is opened, the device box 1 is normally inlet and outlet, and seawater enters the hull through the stealth air intake and exhaust cover. The device box 1 collects the seawater and discharges it reasonably through the drain port to reduce the corrosion of seawater to the equipment. When the stealth air intake and exhaust cover 2 is closed, the air intake and exhaust device must meet the wind and rain tightness requirements and the radar wave stealth requirements of surface ships. The gap between the stealth air intake and exhaust cover 2 and the hull is uniform, and it can withstand the impact of waves without displacement and deflection. At the same time, the stealth air intake and exhaust cover 2 can transmit the opening and closing signal to the remote control end through the limit switch.

[0077] Only the stealth air intake and exhaust cover 2, the driving shaft 6 and the shaft sleeve are arranged inside the device box 1, and an O-ring 3 is arranged at the shaft sleeve. The manual operating device 5 and the cylinder 4 of the stealth air intake and exhaust cover 2 are arranged outside the device box 1 to prevent seawater corrosion.

[0078] If the air intake and exhaust box, the manual operating device 5 , the cylinder 4 , other control devices or equipment need maintenance, it is not necessary to operate in the device box 1 , and related maintenance operations can be performed outside the device box 1 .

[0079] At the same time, the cylinder 4 has a self-locking function. When the stealth air intake and exhaust cover 2 is opened or closed by high-pressure air, if the high-pressure air in the cylinder 4 is cut off, the stealth air intake and exhaust cover 2 can maintain the current state.

[0080] When there is no air in the air circuit, the stealth air intake and exhaust cover 2 can be opened or closed by the manual operating device 5 .

[0081] In order to meet the operating needs of the crew, the manual operating device 5 and the cylinder 4 can also be led to a convenient operating position through a connecting rod to facilitate the actual operation of the crew.

[0082] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
