Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a seabed door grille. Background Art

[0002] In order to prevent foreign matter from being sucked into the seawater tank and contaminating the ballast water system and cooling water system when the ship is running, it is usually necessary to install grille devices on the high and low seabed doors at the seawater inlet. The seabed door grille plays an important role in the navigation of the ship. It not only ensures the smooth flow of seawater into the system, but also effectively protects the ship's equipment from damage by debris. It is an indispensable part of the ship's navigation.

[0003] At present, common submarine gate grilles are made of flat steel splicing or round holes. The grille hinges are opened and closed by the side and are equipped with counterweights. However, the submarine gate grille will make the grille cover as a whole heavier, which makes it very difficult for operators to open or close the grille during operation, affecting the operating efficiency and making it difficult to operate underwater. At the same time, since the submarine gate grille needs to filter debris, various debris often accumulates at the water inlet of the grille, resulting in water blockage. When cleaning the submarine gate grille, personnel usually need to remove the grille from the frame before cleaning, which makes the cleaning process inconvenient.

[0004] Based on this, the present invention designs a submarine door grille to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a submarine door grille.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a seabed gate grille, comprising a surrounding plate, an ear plate, connecting bolts, a grille plate, a hinge seat, a bent plate, a connecting cross bar, a support plate, a limit groove, a cleaning mechanism, an anti-slip mechanism and a locking mechanism, a grille plate is arranged inside the surrounding plate, the grille plate is fixedly connected to the ear plate by connecting bolts, the ear plates are fixedly connected to the inner wall of the surrounding plate, the connecting bolts are locked and fixed by straight pins, a plurality of oblong holes are opened on the grille plate, two hinge seats are symmetrically arranged on the upper end of the grille plate, bent plates are connected in the hinge seats, the two bent plates are fixedly connected by a connecting cross bar, and the two bent plates are fixedly connected to the support plate.

[0007] As a preferred technical solution of the present invention, limiting grooves are symmetrically provided on the inner side wall of the enclosure plate, and a cleaning mechanism is movably provided between the limiting grooves, and the cleaning mechanism is arranged below the grille plate.

[0009] As a preferred technical solution of the present invention, an insertion rod is provided on the hinge seat, and the insertion rod is locked and fixed to the hinge seat by a fixing pin.

[0010] As a preferred technical solution of the present invention, the cleaning mechanism includes a plate body, a handle, a wire brush, a cleaning hook and a limit slider. The lower end of the plate body is fixedly connected to the handle, the upper end of the plate body is provided with a wire brush and a cleaning hook, and limit sliders are provided on both sides of the plate body.

[0011] As a preferred technical solution of the present invention, the limiting sliding blocks on both sides of the cleaning mechanism are respectively slidably arranged in limiting grooves symmetrically opened on the inner side wall of the enclosure.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention designs a new type of submarine door grille. The grille plate adopts the form of oblong hole opening. The size of the opening needs to be designed according to the size of the pump body impeller flow channel to ensure that the size of the debris or particles is smaller than the size of the impeller flow channel. The hinge is installed in the middle position and is welded and fixed to the hull structure with two supporting legs, so that the grille can replace the balancing function of the counterweight block by its own weight. In addition, after the grille is closed, a straight pin is inserted into the bolt opening for locking, which is convenient for underwater operation. The design invention has low cost and simple production. The problem of laborious opening and closing the grille underwater is solved by redesigning the form of the grille.
