Description

[0001] The invention relates to the technical field of life raft performance detection, in particular to a marine life raft performance detection device. Background Art

[0002] A life raft is a non-self-propelled boat used for lifesaving on board a ship. A certain amount of food and fresh water are prepared in the life raft for the occupants to use when drifting on the sea and waiting for rescue. After the life raft is produced, it needs to undergo a number of performance tests to obtain the overall performance data of the life raft, so that the life raft can be used normally in an emergency to ensure the safety of the users.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] like Figure 1As shown, a marine life raft performance testing device includes a base 1, the upper surface of the base 1 is fixedly connected to a testing water pool 6, the outer circumferential surface of the testing water pool 6 is provided with a blowing mechanism 2 for simulating wind force during the testing process, the performance testing device also includes a wave-making mechanism 4 for simulating waves during the testing process, the wave-making mechanism 4 is arranged on the inner wall of the bottom end of the testing water pool 6, the performance testing device also includes an auxiliary mechanism 5 for simulating reefs during the testing process, the auxiliary mechanism 5 is arranged on the testing water pool 6, the performance testing device also includes a recording mechanism 3 for recording the swaying amplitude of the life raft during the testing process, the number of the recording mechanisms 3 is four and they are evenly distributed on the auxiliary mechanism 5.

[0031] During specific use, when the performance of the offshore life raft is tested, the stability of the offshore life raft can be tested through the blower mechanism 2 and the wave-making mechanism 4 in cooperation with the recording mechanism 3; the wear resistance of the offshore life raft can be tested through the setting of the auxiliary mechanism 5; the sealing of the offshore life raft can be tested by comparing the air pressure data before and after the test of the offshore life raft; the overall performance data of the offshore life raft can be obtained after comprehensive analysis of multiple test data.

[0032] like Figure 2 As shown, the wave-making mechanism 4 includes a gas compression unit 43 fixedly connected to the upper surface of the base 1 to provide air pressure, a wave-making bowl 42 that moves up and down is arranged at the center position of the inner wall of the bottom end of the detection pool 6, and a connecting piece 41 that assists the wave-making bowl 42 to move up and down is arranged at the center position of the inner wall of the bottom end of the detection pool 6.

[0033] like Figure 2 As shown, the wave-making mechanism 4 includes a supporting slide 412 fixedly connected at the center position of the bottom end of the inner surface of the detection water pool 6 and a gas compression chamber 413 fixedly connected at the center position of the upper surface of the base 1. The upper surface of the supporting slide 412 slides up and down and is connected with a limiting slide rod 411 through it. The bottom end of the limiting slide rod 411 is fixedly connected to the inner surface of the wave-making bowl 42. The bottom end of the outer surface of the wave-making bowl 42 is fixedly connected with a push rod 414. The push rod 414 penetrates into the interior of the gas compression chamber 413 and is connected to the gas compression chamber 413 by sliding up and down. The outer circumferential surface of the gas compression chamber 413 is fixed and connected with a connecting pipe 415 through it. The end of the connecting pipe 415 away from the gas compression chamber 413 is fixed and connected through it with the gas compression unit 43.

[0034] During specific use, when the stability of the offshore life raft is tested, the gas compression unit 43 provides power to generate compressed air. After the air is pumped into the gas compression chamber 413 through the connecting pipe 415, the compressed air drives the top rod 414 to drive the wave-making bowl 42 to move up and down repeatedly. When the wave-making bowl 42 moves up and down, it drives the limit slide bar 411 to move up and down synchronously. At this time, the limit slide bar 411 slides up and down on the supporting slide 412 to ensure that the wave-making bowl 42 moves up and down in the vertical direction. During the repeated lifting and lowering of the wave-making bowl 42, a pulse is generated each time the wave-making bowl 42 is lifted and lowered, thereby continuously forming concentric water waves on the water surface, simulating waves on the sea, and continuously impacting the offshore life raft inside the detection pool 6, thereby testing the stability of the offshore life raft.

[0035] When the stability of the offshore life raft is detected by the wave-making mechanism 4, different numbers of dummies are placed inside multiple offshore life rafts to simulate the stability of the offshore life rafts subjected to the impact of waves when carrying different weights. The continuous swinging frequency and amplitude of the offshore life raft are recorded respectively by multiple recording mechanisms 3. A comprehensive analysis is performed based on the data recorded by the recording mechanisms 3 and the number of dummies placed inside the offshore life rafts to detect the stability of the offshore life rafts when encountering waves when carrying different weights.

[0036] It is also possible to carry out multiple groups of tests, each of which has a different duration, to test the stability of the marine life raft when encountering waves while carrying different weights at different times.

[0037] like Figure 3 and Figure 4 As shown, the blowing mechanism 2 includes a mounting member 21 disposed on the outer circumferential surface of the detection water pool 6 , and a plurality of blowing units 22 are evenly distributed on the mounting member 21 .

[0038] like Figure 3 and Figure 4 As shown, the mounting member 21 includes an annular track 212 fixedly connected to the outer circumferential surface of the detection water pool 6, a plurality of sickle-shaped mounting seats 215 are circumferentially slidably connected to the upper surface of the annular track 212, a limited connecting plate 214 is detachably installed on the lower surface of the sickle-shaped mounting seat 215, a U-shaped stand 211 is fixedly connected to the upper surface of the sickle-shaped stand 215, the U-shaped stand 211 is hinged to the blowing unit 22 between the opposite surfaces of the two vertical sections, an electric push rod 216 is hinged to the upper surface of the horizontal section of the U-shaped stand 211, and an end of the electric push rod 216 away from the horizontal section of the U-shaped stand 211 is hinged to an end of the blowing unit 22 away from the center of the detection water pool 6.

[0039] like Figure 3 and Figure 4As shown, the limiting connecting plate 214 and the sickle-shaped mounting seat 215 are connected by fastening bolts, the lower surface of the sickle-shaped mounting seat 215 is higher than the lower surface of the annular track 212, and an annular placement groove is provided on the upper surface of the annular track 212. An arc-shaped clamping strip is provided on the horizontal section of the sickle-shaped mounting seat 215 and is adapted to the annular placement groove. The horizontal section of the sickle-shaped mounting seat 215 is in contact with the upper surface of the annular track 212, and the vertical section of the sickle-shaped mounting seat 215 is in contact with the outer circumferential surface of the annular track 212.

[0040] During specific use, when the stability of the offshore life raft is tested by repeatedly raising and lowering the wave-making bowl 42 to generate waves, a blowing unit 22 is provided. Air is blown by the blowing unit 22 and the waves generated by the wave-making bowl 42 are used to simulate windy and choppy weather, so as to test the stability of the offshore life raft after bearing weight in windy and choppy weather.

[0041] By arranging different numbers of blowing units 22, it is also possible to implement stability testing of the offshore life raft in test environments with different wind strengths.

[0042] When blowing air through the blowing unit 22, the blowing unit 22 can be pushed to rotate on the U-shaped stand 211 by the extension and retraction of the electric push rod 216 to adjust the inclination angle of the blowing unit 22, so that the wind direction of the blowing unit 22 can be adjusted to match the waves generated by the wave-making bowl 42 to simulate the wind and wave conditions at sea. At the same time, the sickle-shaped mounting seat 215 is clamped on the annular track 212. After the sickle-shaped mounting seat 215 is slid to a suitable position on the annular track 212, the limiting connecting plate 214 is tightened on the lower surface of the sickle-shaped mounting seat 215 by tightening bolts, and the sickle-shaped mounting seat 215 is kept fixed on the annular track 212 by the limiting connecting plate 214.

[0043] like Figure 3 and Figure 5 As shown, the auxiliary mechanism 5 includes four reef plates 52 evenly distributed on the inner circumference of the detection pool 6, and an auxiliary member 51 for selectively shielding the reef plates 52 is provided on the detection pool 6.

[0044] like Figure 3 and Figure 5 As shown, the auxiliary component 51 includes a mounting box 514 fixedly connected to the lower surface of the detection pool 6 at a position corresponding to the reef plate 52, a through groove is provided at the bottom end of the inner surface of the detection pool 6 and at a position corresponding to the upper surface of the mounting box 514, a baffle 513 is slidably connected to the inside of the mounting box 514, the top of the baffle 513 is slidably connected to the through groove at the bottom end of the inner surface of the corresponding detection pool 6, a connecting piece 512 is fixedly connected to the upper surfaces of two adjacent baffles 513, a hydraulic telescopic rod 511 is fixedly connected to the upper surface of the detection pool 6, and the telescopic end of the hydraulic telescopic rod 511 is fixedly connected to the upper surface of the connecting piece 512.

[0045] In actual use, when testing the surface wear resistance of the marine life raft, firstly a reef is fixed on the reef plate 52 to simulate the situation that the marine life raft hits the reef, so as to test the strength of the marine life raft when the marine life raft rubs and collides with the reef.

[0046] The hydraulic telescopic rod 511 can also be retracted to drive the baffle 513 to slide upward inside the installation box 514 through the connecting piece 512, so that the baffle 513 blocks the reef plate 52. At this time, the performance of the offshore life raft can be tested by simulating the situation without reefs.

[0047] The surface areas of the reefs fixed on the four reef plates 52 can also be set to be different in size, and the distribution of different reefs on multiple life rafts can be compared during the performance test of the life rafts at sea, so as to obtain multiple groups of data for subsequent data comparison.

[0048] like Figure 6 As shown, the recording mechanism 3 includes a motion capture device 31 which is arranged on a hydraulic telescopic rod 511 and can adjust the recording angle and position, and an adjusting member 32 which assists the motion capture device 31 in adjusting the recording angle and position is arranged on the auxiliary member 51 .

[0049] like Figure 6 As shown, the adjusting member 32 includes a rotating base 321 fixedly connected to the top of the hydraulic telescopic rod 511, a clamping sleeve 322 is fixedly connected to the upper surface of the rotating base 321, an adjusting rod 323 is clamped inside the clamping sleeve 322, an adjusting head 324 is hinged at one end of the adjusting rod 323 close to the center of the detection water pool 6, a side of the adjusting head 324 away from the adjusting rod 323 is fixedly connected to the motion capture device 31, the adjusting rod 323 and the clamping sleeve 322 are kept relatively fixed by a limiting bolt, and an adjusting bolt for limiting the position of the adjusting head 324 is arranged between the adjusting head 324 and the adjusting rod 323.

[0050] During specific use, when the swing frequency and amplitude of the offshore life raft are recorded by the recording mechanism 3, in order to facilitate recording, the position and tilt angle of the motion capture device 31 can be adjusted so as to have a better recording angle. The horizontal position of the motion capture device 31 is adjusted by sliding the adjusting rod 323 inside the clamping sleeve 322. After the adjustment is completed, the adjusting rod 323 is firmly fixed inside the clamping sleeve 322 by the limit bolt, and then the adjusting head 324 is rotated on the adjusting rod 323 to adjust the tilt angle of the adjusting member 32. After the adjustment is completed, the adjusting head 324 is fixed on the adjusting rod 323 by the adjusting bolt, so that the motion capture device 31 maintains the adjusted tilt angle.

[0051] When conducting performance testing on offshore life rafts, according to the testing needs, the staff can simulate the above-mentioned multiple real-life situations and make reasonable selections and combinations to simulate the different situations that the offshore life rafts are subjected to in actual use, so as to obtain more accurate performance data of the offshore life rafts.

[0052] Working principle: When in use, first, inflate four marine life rafts to the same air pressure and record the data. Then, evenly distribute the four marine life rafts inside the detection pool 6 and align them with the middle position of the four reef plates 52 in turn. At this time, different numbers of dummies are placed inside the four marine life rafts. Then, the gas compression unit 43 cooperates with the connecting piece 41 to drive the wave-making bowl 42 up and down to create waves inside the detection pool 6. At the same time, the blowing unit 22 is turned on to simulate strong winds. Then, multiple motion capture devices 31 are used to record the shaking amplitudes of multiple marine life rafts when they are affected by wind and waves. After a certain period of detection, all simulation equipment is stopped, and the dummies inside the four marine life rafts are taken out and then taken out from the detection pool 6. At this time, the air pressure of each marine life raft is measured and recorded one by one by the measuring equipment again. After comparison with the initial air pressure, the data recorded by the comprehensive motion capture device 31 is used to obtain the performance data of the marine life raft.
