Problems solved by technology

However, the concave cavity outside the vent is easy to form radar wave reflection, which reduces the stealth performance of ships and ships, and directly affects the completion of related tasks of ships and ships.
Today, the ventilation equipment used is shutters, but the shutters used cannot prevent debris from entering, cannot scatter radar waves, and are not easy to open and close

Embodiment 1

[0016] Such as figure 1 , 2 A doorless watertight shutter shown in and 3 includes a window frame 1 and a venetian blind 2 arranged in the window frame 1, the venetian blind 2 is composed of a plurality of venetian blind blades 2.1 from top to bottom, and the venetian blind 2 The lower sides of both ends of the curtain blade 2.1 are respectively connected to the longitudinal movable struts 9 on both sides through hinges, and the movable struts 9 are installed on the window frame 1 through shafts; The screw rod 3.1 of the hand wheel 3 is in rotational connection with the worm gear 5 arranged at the lower part of the window frame 1, and the worm gear 5 is in transmission connection with the coaxial large gear 6 at both ends, and the large gear 6 meshes with the small gear 7, so that The pinion 7 meshes with the rack 8 provided on the movable pole 9; a shielding net 4 is provided at the rear of the louver, and a sealing device is provided at the front.

[0017] The doorless wate...

Embodiment 2

[0019] On the basis of Embodiment 1, the sealing device includes a sealing groove 10 provided in the window frame 1 and a sealing strip 11 fitted in the sealing groove 10 . It can prevent external rainwater from entering the ventilation device and effectively protect the internal system.

[0020] The shielding net 4 is woven by a warp group and a weft group perpendicular to each other, and the warp group and the weft group are composed of two parallel single wires, and the two single wires are polyester fiber wires and copper alloy wires respectively. The outer surface of the polyester fiber wire is coated with a copper alloy coating, the surface of the copper alloy coating is coated with a polyester protective layer, and the surface of the copper alloy wire is coated with a polyester protective layer. It can avoid external electromagnetic interference, prevent radar from passing through, and can effectively prevent debris from entering the ventilation system, improving the me...

Abstract

The invention relates to a shutter, and particularly provides a door-free watertight shutter which comprises a window frame and a shutter blind arranged in the window frame. The shutter blind is composed of a plurality of shutter blind blades from top to bottom. The lower sides of the two ends of the shutter blind blades are connected with longitudinal movable support rods on the two sides of the shutter through hinges correspondingly. The movable support rods are mounted on the window frame through shafts. The door-free watertight shutter further comprises a hand wheel arranged outside the window frame. A screw of the hand wheel is rotatably connected with a worm wheel arranged on the lower portion in the window frame. The worm wheel is in transmission connection with coaxial big gear wheels at the two ends. The big gear wheels are engaged with pinions engaged with racks arranged on the movable support rods correspondingly. A shielding net is arranged on the rear side of the shutter. A sealing device is arranged on the front side of the shutter. The door-free watertight shutter is simple in structure, convenient and flexible to operate and good in sealing and shielding effect, impurities can be prevented from entering the shutter, radar waves can be effectively scattered, and a very good camouflage effect can be achieved.

Description

technical field [0001] The invention relates to a louver, in particular to a ship and a doorless watertight louver used on a ship. Background technique [0002] In order to solve the air volume required by combustion equipment and the heat dissipation of equipment and components during normal operation on ships and warships, ventilation openings must be provided on the bulkhead, and ventilation equipment that can be closed should be provided at the ventilation openings. Close the vents during heavy rain. However, the concave cavity outside the vent is easy to form radar wave reflection, thereby reducing the stealth performance of ships and ships, and directly affecting the completion of related tasks of ships and ships. Today, the ventilation equipment used is shutters, but the shutters used cannot prevent debris from entering, cannot scatter radar waves, and are not easy to open and close. Contents of the invention [0003] The object of the present invention is to over...
