Embodiment Construction
[0028] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0029] Such as Figure 1 to Figure 5 As shown, the technical solution of the present invention is: an automatic folding fully sealed air intake and exhaust device, including a support base 1, a rotating shaft 2, an air intake and exhaust device 3, an upper exhaust pipe 4, and a rubber bellows 5 , pressure rod 6, wedge 7, combined sealing ring 8, locking hydraulic cylinder 9, locking bracket 10, lower exhaust pipe 11, lifting hydraulic cylinder 12, rear travel switch 14, front travel switch 15;
[0030] Wherein, a sealing ring installation groove is opened on the support base 1; a rotating ear is provided on the upper side of the front end of the suppo...

The invention discloses an automatic folded-down type fully-sealed air intake and exhaust device. The device can realize that the air intake and exhaust device is stably and automatically folded down and vertical; after the device is vertical, locking sealing of the air intake and exhaust device and a supporting base and dynamic sealing between an upper air exhaust pipe and a lower air exhaust pipe can be realized. The following specific measures are adopted: firstly, a built-in balance valve is arranged on a rise-and-fall hydraulic cylinder, so that when the air intake and exhaust device is folded down and runs vertically, the movement is smooth, and the device cannot fall down quickly because of gravity or other conditions; secondly, an irregularly-shaped combined seal ring is used between the air intake and exhaust device and the supporting base, the problem of the air intake and exhaust device that the seal ring is extruded out from a groove during the process that the seal ring is rotated and compressed is prevented; thirdly, a locking hydraulic cylinder piston head is connected with a wedge, the lower end face of the wedge is designed into an oblique plane, a sliding key is arranged on the oblique plane, and a pressure lever matched with the wedge is also designed into an oblique plane, thus the wedge and the pressure lever are matched with each other conveniently, and the wedge is prevented from being blocked and rotating during the movement process.
Description
technical field [0001] The invention belongs to the technical field of airtight air intake and exhaust devices, and in particular relates to an automatic folding fully sealed air intake and exhaust device. Background technique [0002] In order to safeguard the national marine interests and ensure the security of the marine land and environment, it is imperative to develop marine high-tech equipment for both military and civilian use. From the analysis of the development situation at home and abroad in recent years, it is necessary to develop a detection capability at a certain depth underwater, which is used to identify dangerous targets detected, and has flexible navigation, certain wind and wave resistance, and better concealment. own aircraft. [0003] When the underwater vehicle is working normally, the air intake and exhaust port of the intake and exhaust device are exposed to the water surface to provide the diesel engine in the vehicle with the air required for work...
