Abstract

The present invention relates to hatch cover for internal river cargo ship, and is especially one light folding hatch cover comprising several connected cover plates. Several cover plates are connected successively via hook mechanism, supported on guiding support mechanism, and stored inside the storing chamber on one end of the guiding support mechanism. The cover plates may be withdrawn from the storing chamber one by one during covering the hatch or collected and folded into the storing chamber one by one during collection. The folding hatch cover is flexible, large in covered area, beautiful and good in sealing performance.

Description

【Technical field】 [0001] The invention relates to a cargo hatch cover of an inland ship, in particular to a lightweight self-folding hatch cover which is formed by connecting a plurality of cover plates and is easy to store. 【Background technique】 [0002] The means of transportation adopting the closed mode of transportation of goods has the advantages of cleanliness, environmental protection and beauty. At present, developed countries have basically adopted closed modes of transportation in terms of road transportation and waterway transportation. There are no clear regulations in this regard in our country, but with the acceleration of the modernization process, the whole society's requirements for environmental protection, cleanliness and aesthetics are constantly increasing, and the closed transportation of goods is the development trend of various transportation tools. [0003] At present, ships transported by inland waterways all have open cargo hatches, and when the ...
