Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The first embodiment of the sea chest grating of the present invention, as shown in fig. 1 to 3, comprises a grating base 1 and a grating 2 rotatably mounted in the grating base 1. Grid seat 1 is fillet rectangle frame structure, and grid 2 be with grid seat 1 assorted fillet rectangle structure, has the pivot 3 of inside extension on grid seat 1 length direction's the inner wall, have on grid 2 with 3 cartridge complex perforations of pivot, 3 cartridges of pivot realize the rotation assembly of grid 2 and grid seat 1 in the perforation.
The extension direction of the rotating shaft 3 is defined as the front-back direction, the rotating shaft 3 is positioned on the left side of the middle position of the left-right direction of the grating seat 1, and the length of the grating positioned on the left side of the rotating shaft 3 is smaller than that of the grating positioned on the right side of the rotating shaft. The grille holder 1 is provided with a plurality of first lug plates 6 which extend horizontally and inwards on the inner wall of the left side of the rotating shaft, and the first lug plates 6 are used for limiting the downward rotation of the grille 2 which rotates downwards so as to keep the grille 2 in a horizontal state. The grille holder 1 is also provided with a plurality of second lug plates 7 which extend horizontally and inwards on the inner wall on the right side of the rotating shaft, and the second lug plates 7 are used for limiting the upward rotation of the grille 2 which rotates upwards so as to keep the grille 2 in a horizontal state. The first ear plate 6 is located on the lower side of the second ear plate 7 and the vertical distance between the first ear plate 6 and the second ear plate 7 is equal to the thickness of the grating 2. Be provided with the perforation on first otic placode 6 and the second otic placode 7 respectively, have on the grid 2 and correspond the through-hole that link up with each first otic placode 6 and second otic placode 7, when grid 2 was in the closure state, fixing bolt 9 worn the dress in perforation and through-hole, realized grid 2 and grid seat 1's fixed connection.
In this embodiment, a balance weight is provided on the grid 2 on the left side of the rotating shaft 3. Preferably, the counterweight is a counterweight grid 4, and the counterweight grid 4 extends out of the upper side and the lower side of the grid 2. When grid 2 was opened, because of 3 right sides of pivot grids 2 parts are greater than 3 left side grids 2 parts of pivot, when no counter weight grid 4, grid 2 on right side can be rotated downwards under the action of gravity, has the danger of pounding underwater diver in the middle of the object. After the counter weight grating 4 is added on the grating 2 on the right side of the rotating shaft 3, the grating 2 on the right side cannot rotate automatically under the action of gravity under the action of the counter weight grating 4, so that the risk of underwater divers smashing by the grating 2 is effectively avoided.
In this embodiment, the grille 2 is sleeved with a torsion spring 5, one of the force-bearing arms of the torsion spring 5 is fixed on the grille seat 1, and the other force-bearing arm is fixed on the grille 2. When the grating 2 on the right side of the rotating shaft 3 rotates downwards, the torsion spring 5 applies an upward acting force to the grating 2 on the right side of the rotating shaft 3. Under the action of the counterweight grids 4 and the torsion springs 5, the torsion springs 5 at the left and right ends of the grids 2 are approximately the same.
When the grating 2 rotates downwards to a vertical state, a rectangular opening for people to pass through is formed on the right side of the rotating shaft 3, the length of the rectangular opening is 600mm, and the width of the rectangular opening is 400 mm.
In the embodiment, the grating 2 is made of glass fiber reinforced plastics, and the glass fiber reinforced plastics are light in weight and corrosion resistant, so that the service life of the grating 2 can be prolonged; at the same time, the lighter glass fibre reinforced plastics contribute to reducing the overall weight of the subsea door grille and reduce the moment of inertia generated when the grille 2 is opened.
The working principle of the sea chest grating of the invention is as follows: referring to fig. 2 and 3, when the grille 2 is in a closed state, the fixing bolt 9 fixedly connects the grille 2 to the first and second ear plates 6 and 7. When needs open grid 2, pull down fixing bolt 9, grid 2 can not be by oneself down rotation under the effect of counter weight grid 4, and when the grid 2 of the manual downward pulling pivot 3 right side of diver rotated downwards, ascending effort was applyed to grid 2 to torsional spring 5, when grid 2 rotated to vertical state, the opening that supplies the people to pass through was formed on the 3 right sides of pivot, when grid 2 was closed to needs, under torsional spring 5's effect, diver closed grid 2 more easily.
The invention provides a submarine gate grating, which has the following advantages compared with the prior art: according to the submarine door grating, the balance weight is arranged on the grating 2, so that when a diver operates underwater, the submarine door cannot be closed and closed automatically due to the balance weight after the submarine door grating is opened. When closing the sea chest grating, torsional spring 5 can be used to exert ascending effort to the sea chest grating, provides the helping hand for closing the sea chest grating. Compared with the submarine door grating in the prior art, the submarine door grating helps to prevent the opened submarine door grating from closing by itself and helps an operator to close the opened submarine door grating. In addition, the sea chest grating of the invention only needs to fix the grating seat 1 and the ship body 8, and the installation is simple and convenient.
The second embodiment of the sea chest grating of the invention is different from the first embodiment of the sea chest grating in that the rotating shaft in the embodiment is arranged on the grating, and the grating seat is provided with a connecting hole for inserting the grating. The rest is the same as the first embodiment, and is not described again.
The third embodiment of the subsea door grid of the present invention is different from the first embodiment of the subsea door grid in that in this embodiment, the counterweight is a solid counterweight. The rest is the same as the first embodiment, and is not described again.
The fourth embodiment of the subsea door grid according to the present invention differs from the first embodiment of the subsea door grid in that in this embodiment the first and second ear plates are replaced by stop bars provided on the grid base. The rest is the same as the first embodiment, and is not described again.
The specific embodiment of the ship comprises a hull bottom door grating, wherein the hull is provided with an opening matched with the bottom door grating, and the bottom door grating is fixed at the opening. The structure of the sea chest grating in this embodiment is the same as that of the sea chest grating in the above embodiments, and the description thereof is omitted.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
