Description

Technical Field

[0002] Life rafts are life-saving facilities and equipment equipped on ships for emergency escape from dangerous areas or emergency evacuation from distressed ships. Among them, inflatable life rafts have the advantages of small storage volume, light weight, and strong wind and wave resistance of flexible structure. The pressure releaser is the trigger device of the inflatable life raft. When the ship sinks to a certain depth underwater, the pressure releaser will automatically trigger the spring cutter under the action of water pressure to cut the fixed rope between the inflatable life raft and the hull, and then the life raft will float to the surface and automatically inflate into shape.

[0003] The existing life raft pressure releaser is tested by manually placing it in the water, which is inefficient. The current life raft pressure releaser testing equipment can only test one pressure releaser at a time, which cannot meet the needs of actual production. In addition, because water is flowing and the water pressure in different places in the water will be different, vertically lifting the pressure releaser for testing cannot truly simulate the underwater situation, which further leads to inaccurate test results.

The lifting plate 7 and the rotating shaft 8 are symmetrical to each other. One end of the rotating shaft 8 is welded and fixed to the side of the detection cylinder 9. A gear 10 is welded at the center of the detection cylinder 9. The gear 10 is meshed with a tooth plate 11. The side of the tooth plate 11 is welded and fixed to the inner wall of the water tank 1. The length of the tooth plate 11 is the same as the height of the water tank 1. Four slots 12 are provided on the detection cylinder 9. The slots 12 are of the same size and are located on the same horizontal line. A pressure sensor 13 is bonded to the bottom of the slot 12. The pressure sensor 13 is electrically connected to the controller through a wire. The slot 12 is plugged into the pressure releaser body 14. Two fixed slots 15 connected to the slots 12 are provided in the detection cylinder 9. A spring 16 is welded in the fixed slot 15. The fixed slot 15 is plugged into the fixed column 17. The spring 16 is located between the fixed slot 15 and the fixed column 17. The pull rod 18 passes through the side of the detection cylinder 9 and extends to the fixed slot 15 and is welded to the side of the fixed column 17.

[0022] Four support columns are fixedly connected to the lower surface of the bottom of the water tank 1, and the support columns are used to improve the stability of the detection equipment. A sealed bearing is provided at the bottom of the water tank 1, and the fixed plate 2 is rotatably connected to the bottom surface of the water tank 1 through the sealed bearing. The sealed bearing improves the sealing inside the water tank 1 to prevent water from leaking from the connection. A rectangular notch is opened on the side of the water tank 1, and the rectangular notch makes it easy for the detection personnel to install and disassemble the pressure releaser body 14 on the detection tube 9. There are two lifting plates 7 and two rotating shafts 8, and the lifting plates 7 and the rotating shafts 8 are symmetrical to each other. The rotating shaft 8 is rotatably connected to the lifting plates 7 through bearings, and the detection tube 9 can be rotated through the rotating shaft 8, so that the pressure releaser body 14 can be further rotated underwater for detection, thereby improving the accuracy of the detection. The gear 10 is located at the center of the detection tube 9, and the tooth plate 11 is located at the center of the water tank 1.

The slot 12 can cooperate with the fixing column 17 to fix the pressure releaser body 14. The setting of the slot 12 makes the disassembly and installation of the pressure releaser body 14 more convenient and effective. The spring 16 is cylindrical in shape, and the cylindrical shape can better fix the pressure releaser body 14 and facilitate the rotation of the pressure releaser body 14. The inner diameter of the spring 16 is matched with the outer diameter of the fixing column 17. The fixing column 17 is slidably connected to the spring 16. An anti-skid pad is connected to one side of the fixing column 17 by bolts. The anti-skid pad can effectively prevent the pressure releaser body 14 from slipping out of the slot 12 during rotation. One end of the pull rod 18 passes through the detection tube 9 and extends into the fixing slot 15 and is fixedly connected to the side of the fixing column 17. One end of the pull rod 18 is fixedly connected to two fixing columns 17, which effectively reduces the difficulty of installing and fixing the pressure releaser body 14 and improves the efficiency of installing and fixing the pressure releaser body 14.

[0023] Working principle: When in use, the inspector manually pulls out the pull rod 18, which will drive the fixed column 17 to move outward and compress the spring 16 at the same time. Then, the bottom of the pressure releaser body 14 to be inspected is inserted into the slot 12 and the pull rod 18 is released. The fixed column 17 will fix the pressure releaser body 14 in the slot 12 under the action of the spring 16 to prevent the slot 12 from falling off during rotation. After several pressure releaser bodies 14 are fixed in the slot 12, the motor 6 is driven to rotate the threaded rod 3. The rotation of the threaded rod 3 causes the transmission wheel 4 to rotate, that is, the transmission belt 5 drives another threaded rod 3 to rotate synchronously, and further causes the lifting plates 7 on both sides to descend synchronously. At this time, the lifting plates 7 drive the rotating The moving shaft 8 and the detection tube 9 move downward, and while the detection tube 9 moves downward, the gear 10 rotates under the action of the toothed plate 11, and the detection tube 9 is further rotated with the cooperation of the rotating shaft 8, so that the detection tube 9 rotates itself while moving downward, which more realistically simulates the underwater water pressure and improves the reliability of the detection result. When the detection tube 9 and the pressure releaser body 14 move downward, the spring knife in the pressure releaser body 14 will pop out and squeeze the pressure sensor 13 under the action of the water pressure, and the pressure sensor 13 will transmit the signal to the controller to detect the pressure releaser body 14. If the pressure sensor 13 inside the slot 12 does not send a signal, it means that the spring knife in the corresponding pressure releaser body 14 has not popped out.
