Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
Example 1
As shown in fig. 1 and 2, a deck hatch structure for preventing uncontrolled firing, comprising: a hatch cover body 1 and a safety cover body 2; the edge of the safety cover body 2 is provided with a step 4, the safety cover body 2 is arranged in the hatch cover main body 1 through the step 4, and the step 4 is clamped on one side of the hatch cover main body 1; a plurality of breaking screws 6 are arranged on the safety cover body 2, and the whole cover body 2 is fixedly connected with the hatch cover main body 1 through the breaking screws 6; a locking mechanism 3 is arranged on one side of the hatch cover main body 1, and the hatch cover main body 1 is installed on a deck cabin and locked through the locking mechanism 3. One side surface of the safety cover body 2 extends outwards to form a step 4; inside safety cover body 2 set up 4 one sides of step and deviate from the deck cabin, inside safety cover body 2 did not set up 4 one sides of step and is close to the deck cabin. The cabin cover main part 1 is internally provided with a through hole which is the same as the safety cover body 2 in shape of the side surface of the step 4, the safety cover body 2 is installed in the through hole without being provided with the step 4, and the safety cover body 2 is arranged on one side of the step 4 and is clamped outside the through hole through the step 4. A guided missile is arranged in the deck cabin, and the resistance formed by the safety cover body 2 through the breaking screw 6 is smaller than the thrust of the guided missile to the safety cover body 2 after ignition; the safety cover body 2 blocks external factors from entering the interior of the deck cabin through the step 4.
As shown in fig. 2 to 4, the middle of the safety cover 2 is provided with a circular surface, and four support arms 5 radially extend outwards from the circular surface; each supporting arm 5 is provided with a plurality of breaking screws 6 by adopting a countersunk hole design; an included angle of 45 degrees is formed between every two adjacent supporting arms 5;
the invention also provides a deck cabin which uses the deck cabin cover structure for preventing the uncontrolled launching.
Example 2
Example 2 is a preferred example of example 1.
The hatch cover main body 1 and the safety cover body 2 are assembled through the steps 4 and are fixedly connected through the snapping screws 6; the resistance for opening the safety cover body 2 from the lower part of the deck, namely the cabin to the outside of the cabin, is designed according to the thrust of the missile during takeoff and is far less than the resistance for reversely opening the safety cover body 2.
16 breaking screws 6 on four supporting arms 5 of the safety cover body 2 are connected and fastened with the hatch cover main body 1, the fastening force of the 16 breaking screws 6 is about 0.8 time of the ignition thrust of an engine, and the breaking screws 6 are installed by adopting a countersunk hole design. Because the periphery of the safety cover body adopts a step-type design structure, the forward pressure (from the outside of the cabin to the inside of the cabin) borne by the safety cover body is far greater than the reverse pressure (from the inside of the cabin to the outside of the cabin, and the safety cover body is connected and fixed only by the breaking screw 6).
When the guided missile stored on the ship is accidentally ignited under the condition that the deck hatch cover is closed, the safety cover body 2 can be broken by the guided missile, the breaking resistance of the safety cover body 2 from the inside to the outside of the cabin is not greater than the ignition thrust of a guided missile engine, and the guided missile flies away from the ship, so that the safety of the ship is ensured; meanwhile, in order to ensure the safety of equipment in the cabin during operation, the burst resistance of the safety cover body 2 from the outside of the cabin to the inside of the cabin is far larger than that of the safety cover body 2, and the connection edge structure of the safety cover body 2 and the cabin cover main body 1 is connected by adopting the step 4. When pressure or impact is applied from the deck to the cabin, the safety cover 2 cannot be flushed open due to the form of the step 4 connection between the two unless the impact force of the impact is sufficient to break the safety cover 2 or the hatch cover body 1.
