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

[0031] Such as figure 1 , 2 A sealed watertight louver 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 The lower sides of the two ends of the 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 connected in rotation 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 pinion 7. The pinion 7 meshes with the rack 8 arranged on the movable pole 9; the shielding net 4 is arranged at the rear of the louver, and a sealing device is arranged at the front. On the basis of Embodiment 1, the sealing device ...

Embodiment 2

[0039] On the basis of Example 1, the shielding net 4 is woven from mutually perpendicular warp thread groups and weft thread groups, and the warp thread group and weft thread group are composed of two parallel single lines, and the two single lines are respectively polyester fibers Wire and copper alloy wire, 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 layer. It can avoid external electromagnetic interference, prevent radar from passing through, and can effectively prevent sundries from entering the ventilation system, improving the mechanical strength and shielding performance of the shielding net.

[0040] Such as figure 2 As shown, the movable strut 9 is provided with a waist-shaped hole 13 , and the movable strut 9 is installed on the window frame 1 through an ax...

Embodiment 3

[0042] On the basis of Examples 1 and 2, the present invention also provides a method for preparing the sealing strip for sealing watertight shutters. The step of preparing the sponge core includes: adding the prepared sponge core raw materials into the stirring device and stirring for half Hours, so that the raw materials are mixed evenly, put the mixture into the foaming tank, the foaming temperature is 20-60°C, the foaming time is 2-5 hours, after cooling to room temperature, the molded sponge is obtained, and the molded sponge is soaked in the flame retardant 4-8 hours, then dry in the shade;

[0043] The steps for preparing the rubber foreskin include: (1) Raw material preparation: Prepare the raw materials according to the weight parts, dry the epoxidized natural rubber and EPDM rubber in a drying room at 60-70°C until softened, then cut and break the rubber. Small pieces; crush rosin, stearic acid and phenolic resin, and screen them to remove mechanical impurities or co...

Abstract

The invention relates to a blind window and particularly provides a sealed watertight blind window. The sealed watertight blind window comprises a window frame and a venetian blind arranged in the window frame. The venetian blind is composed of multiple venetian blind vanes which are arranged from top to bottom. The lower sides of the two ends of the venetian blind vanes are connected with longitudinal movable support rods at the two sides through hinges correspondingly. The movable support rods are mounted onto the window frame through shafts. The sealed watertight blind window further comprises a hand wheel arranged outside the window frame. A threaded rod of the hand wheel is connected with a worm wheel arranged on the lower portion inside the window frame in a rotary manner. The worm wheel is in transmission connection with coaxial large gears at the two ends. Each large gear is engaged with a corresponding small gear. Each small gear is engaged with a rack arranged on the corresponding movable support rod. A shielding net is arranged behind the blind window, and a sealing device is arranged in front of the blind window. The sealing device comprises a sealing groove and a sealing strip, wherein the sealing groove is formed in the window frame, and the sealing strip is arranged in the sealing groove in an attached manner. The sealed watertight blind window is good in sealing effect and shielding effect and capable of preventing foreign matter from entering therein and effectively scattering radar waves, and a quite good hiding effect is achieved.

Description

technical field [0001] The invention relates to a louver, in particular to a ship and a 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 overcome the ...
