[0018] Please see Figure 1-8 To improve range and reduce energy consumption, electric bulk carriers face higher demands for lightweight hull design. Hatch covers, as crucial structural components, directly impact a vessel's cargo capacity and overall performance. Therefore, developing a lightweight yet sufficiently strong hatch cover is of great significance. Based on this, this application provides a lightweight composite material hatch cover for electric bulk carriers, comprising a hatch cover 2 for closure and an outer edge 1 adapted to the hatch cover 2. The hatch cover 2 includes a cover body 25, which is disposed on the top of the flange and is sealed to the outer edge 1; A lifting ring 22 is provided at the top center of the cover 25 for lifting the cover 25; The cover 25 includes a body 251, and the top of the body 251 has uniformly spaced, annular anti-compression ribs 252. The body 251 has a through hole 253 in the middle for personnel to pass through.

[0019] The body 251 is made of multi-layer composite materials and manufactured through a vacuum infusion process to ensure uniform material distribution and structural stability, such as carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP), to ensure the hatch cover is lightweight and highly rigid.

[0020] Annular, evenly spaced pressure-resistant ribs 252 are provided on the top of the main body 251 to enhance the pressure resistance of the cover 25 and prevent deformation caused by the pressure of the goods on the cover 25.

[0021] A through hole 253 is provided in the middle of the main body 251 to facilitate personnel getting on and off the ship. At the same time, the structure around the through hole 253 is reinforced to ensure safety.

[0022] A high-performance sealing strip, such as ethylene propylene diene monomer (EPDM) rubber, is installed between the cover 25 and the outer edge 1 to ensure the watertightness and airtightness of the hatch.

[0023] A lifting ring 22 is provided at the top center of the cover 25 to facilitate the operator in lifting the cover 25. The lifting ring 22 should be designed to be made of high-strength, corrosion-resistant metal and should be securely connected to the cover 25.

[0024] The hatch cover is aligned with the outer edge 1 of the hull hatch via its outer edge 1 and is secured by bolts or other fastening devices.

[0025] The use of composite materials significantly reduces the weight of hatch covers, improves the ship's cargo capacity and fuel efficiency, and has excellent strength and corrosion resistance, extending the service life of hatch covers.

[0031] Arc-shaped strips 255: Arc-shaped strips 255 are arranged in a ring at uniform intervals on the outer side of the reinforcement 254. These arc-shaped strips 255 are embedded between two pressure-resistant ribs 252 to further enhance the structural strength and pressure resistance of the cover 25.

[0032] A set of two symmetrically arranged lever arms 23 are provided on the outer side of the cover 25. The material of the lever arms 23 should be a high-strength, lightweight alloy or composite material to ensure structural stability and ease of operation.

[0033] A transmission rod 24 is provided at the end of each lever arm 23 away from the cover 25 to connect the lever arms 23. The design of the transmission rod 24 should ensure uniform force transmission and facilitate the operator to open and close the hatch cover through the lever arms 23 and the transmission rod 24.

[0034] An observation window 21 at a preset angle is provided on the top of the cover 25, and the observation window 21 is parallel to the pull ring. The material of the observation window 21 should be a transparent, high-strength material (such as polycarbonate) to ensure transparency and impact resistance.
