DETAILED DESCRIPTION

[0028] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0029] In the present invention, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] See also Figure 1-4 The seawater immersion test system shown includes a test bench 1 and a test pool 2 installed on the test bench 1. A rotating lifting mechanism 8 is installed on one side of the test pool 2 on the test bench 1. The rotating lifting mechanism 8 includes a discharge platform installed above the test pool 2. The discharge platform is configured to be able to be placed in the test pool 2 in a vertical direction.

[0031] Through the implementation of the above technical solution, the seawater immersion test system can easily place the test piece 24 in seawater for testing. The depth of the test piece 24 immersed in the seawater is adjustable, and various immersion states can be simulated. Specifically, a U-shaped frame 9 is installed at the shaft end of the rotating lifting mechanism 8, and the distal end of the U-shaped frame 9 is connected to the discharge platform. The position of the discharge platform is controlled by the rotation and lifting of the rotating lifting mechanism 8, which facilitates the control of the immersion state of the test piece 24.

[0032] In this embodiment, a base 15 is mounted at one end of the test pool 2. A pH detection probe 16 and a temperature detection probe 17 are mounted on the base 15 and inserted into the test pool 2. This arrangement enables real-time monitoring of the pH and temperature of the test seawater, enabling more accurate testing. Furthermore, the base 15 has vertical surfaces on its inner side to protect against the impact of simulated waves.

[0033] In this embodiment, a stirring impeller 3 is mounted at the other end of the test tank 2; the upper end of the stirring impeller 3 is configured to rotate toward the base 15. The rotation of the stirring impeller 3 creates turbulence in the seawater, thereby simulating waves and the state of the test piece 24 in a wave environment.

[0034] In this embodiment, in order to better simulate the effect of ocean waves, a multi-layer spoiler 3 with adjustable angle is provided between the discharge platform and the stirring impeller 3 .

[0035] In this embodiment, the multi-layer spoiler 3 is fixed to both ends of the multi-layer spoiler 3 with end plates 5. The outer ends of the end plates 5 are connected to a rotating shaft 31, which is connected to a motor that drives the rotating shaft 31. The rotation of the motor drives the multi-layer spoiler 3 to rotate synchronously, thereby simulating different forms of wave effects.

[0036] In this embodiment, in order to achieve a better simulated wave effect, the multi-layer spoiler 3 is wavy in shape. An inclined flat extension plate 32 is also provided at one end of the wavy plate close to the impeller 3, so that seawater can enter the gaps between the wavy plates more smoothly to form a stable turbulent flow.

[0037] In this embodiment, the test tank 2 is equipped with a first water inlet pipe, a second water inlet pipe, and a drain pipe 7. A heat pump 18 and a compressor 21 are installed on the first and second water inlet pipes, respectively. Both are connected to a main water inlet pipe 19, which is also equipped with a high-pressure water pump 20. This setup utilizes natural seawater as the raw material for the test seawater, simulating a realistic seawater environment. The temperature of the test seawater is controlled by the selective use of the heat pump 18 and compressor 21.

[0038] In this embodiment, the discharging platform includes a fixed plate 12 and two movable frames 10 symmetrically arranged on the fixed plate 12; an L-shaped frame 23 is installed at the lower end of the two movable frames 10, a servo motor 6 is installed on the fixed plate 12, and the shaft of the servo motor 6 is connected to a bidirectional screw 13; the two ends of the bidirectional screw 13 are respectively screwed to the two movable frames 10; a guide light rod 11 is also provided on the fixed plate 12, which passes through the two movable frames 10, and the two ends of the guide light rod 11 are fixedly connected to the limiting plate 14.

[0039] With this arrangement, the distance between the two L-shaped frames 23 can be adjusted closer or further apart by the rotation of the servo motor 6, thereby enabling seawater immersion experiments on test pieces 24 of varying sizes. A fine-tuning frame 22 can also be provided between the L-shaped frames 23 and the lower end of the movable frame 10 to fine-tune the distance between the L-shaped frames 23. This can be achieved, for example, by rotating a pitch-adjusting screw.

[0040] In this embodiment, in order to further provide an L-shaped frame 23, the L-shaped frame 23 includes a vertical plate 26 and a horizontal plate 25 connected vertically, and a plurality of rectangular holes 27 are arranged on the vertical plate 26 and the horizontal plate 25, and a plurality of protruding supports 28 are provided between two adjacent rectangular holes 27.

[0041] This arrangement allows the test seawater to contact the test piece 24 through the rectangular hole 27, increasing the contact area and improving the experimental effect. A mounting bracket 29 and mounting holes 30 are also provided on the back of the vertical plate 26. Bolts passing through the mounting holes 30 connect the vertical plate 26 to the lower end of the movable frame 10.

[0042] The present invention also provides a seawater immersion test method, which uses the seawater immersion test system and includes the following steps:

[0043] S1, by rotating the lifting mechanism 8, the unloading platform carrying the test piece 24 is assisted to be immersed in the seawater in the test tank 2 as required;

[0044] S2, the stirring impeller 3 provided at the end of the test tank 2 rotates to drive the seawater in the test tank 2 and simulate the wave state;

[0045] S3, after the test is immersed for a period of time, the test piece 24 is taken out and various properties of the test piece 24 are tested, and the test values ​​are compared with the required values ​​to determine whether the test piece 24 meets the requirements.

[0046] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0048] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
