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.
Nowadays, 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, and the sealing effect is not good
The sealing device used is easily corroded by seawater and has a relatively short service life

Embodiment 1

[0025] Such as figure 1 , 2 A marine 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 blades 2. The lower sides of both ends of 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 located at the lower part of the window frame 1, the worm gear 5 is in transmission connection with the coaxial large gear 6 at both ends, the large gear 6 meshes with the pinion 7, and the small The gear 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; The sealing strip in the sealing groove can prevent extern...

Embodiment 2

[0032] On the basis of Embodiment 1, the shielding net 4 is woven from mutually perpendicular warp thread groups and weft thread groups, and the warp thread group and the weft thread group all have 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 Floor. 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.

[0033] 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

[0035]On the basis of Examples 1 and 2, we also provide a method for preparing the sealing strip of the marine shutter, which includes the following steps: (1) Prepare raw materials: prepare the raw materials according to parts by weight, and prepare the ethylene-propylene rubber Cut and break the rubber into small pieces after drying with isoprene rubber in a drying room at 60-70°C; crush paraffin, stearic acid and sulfur, and screen them to remove mechanical impurities or coarse particles; base silicone oil and aromatic oil for heating, evaporating water, and filtering impurities;

[0036] (2) Masticating: Turn on the internal mixer, add ethylene-propylene rubber and isoprene rubber into the internal mixer, the internal mixing temperature is 90-100°C, the internal mixing time is 5-10 minutes, and the temperature of the internal mixer is raised To 100-110°C, constant temperature banburying for 2-5 minutes;

[0037] (3) Mixing: Put the masticated rubber, methyl silicone oil, ...

Abstract

The invention relates to a window shutter, and particularly provides a sealed watertight window shutter. The window shutter comprises a window shutter frame and a shutter blind arranged in the window shutter frame, wherein a plurality of shutter blind blades are arranged from top to bottom to form the shutter blind; the lower sides of two ends of the shutter blind blades are separately connected with longitudinal movable supporting rods on two sides through hinges; the movable supporting rods are mounted on the window shutter frame through shafts; the window shutter further comprises a handwheel arranged on the outer side of the window shutter frame; a screw rod of the handwheel is rotationally connected with a worm wheel at the inner lower part of the window shutter frame; the worm wheel is connected with coaxial bull wheels at two ends in a transmission manner; the bull wheels are meshed with pinions; the pinions are meshed with racks arranged on the movable supporting rods; a shielding mesh is arranged behind the window shutter, and a sealing device is arranged in front of the window shutter; the sealing device comprises a sealing slot formed in the window shutter frame and a sealing strip arranged in the sealing slot in an attaching manner. The marine window shutter, which is provided by the invention, is simple in structure, convenient and flexible to operate and good in sealing and shielding effect, and can prevent debris from entering and effectively scatter radar waves to achieve an extremely good hiding effect.

Description

technical field [0001] The invention relates to a shutter, in particular to a ship and a shutter 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, are not easy to open and close, and have a poor sealing effect. The adopted sealing device is easily corroded by seawater and has a relat...
