Description

Technical Field

[0001] This utility model relates to the technical field of seawater corrosion resistance testing devices, specifically, to a seawater corrosion resistance testing device for a chemical-resistant, seawater-resistant, thermally conductive composite material. Background Technology

[0002] Chemical-resistant and seawater-resistant thermally conductive composite materials are widely used in marine engineering, shipbuilding, seawater desalination and other fields because they combine corrosion resistance and thermal conductivity. Their seawater corrosion resistance directly determines the service life and operational safety of equipment. Currently, the seawater corrosion resistance test of this type of composite material mostly relies on traditional static immersion devices, which involve immersing the sample in seawater in a fixed container and periodically taking it out to test the degree of corrosion.

[0003] When using a static immersion seawater corrosion testing device, traditional testing devices typically store seawater directly in a corresponding container and then immerse the test sample in the seawater within the container for testing. This type of operation can be performed normally for samples that are heavy and whose gravity is greater than their buoyancy. However, when encountering samples whose gravity is less than their buoyancy, the samples will always float on the water surface, affecting the integrity and effectiveness of the test.

[0004] Some testing devices, to prevent samples from floating on the water surface, typically use clamps to hold the samples before immersing them in seawater for testing. While this achieves the desired testing effect, the clamping range is limited, making it unsuitable for samples of various sizes. Furthermore, if the clamps are made of metal, prolonged immersion in seawater can easily lead to corrosion, affecting the effectiveness and lifespan of the device. Therefore, we propose a seawater corrosion resistance testing device using a chemically resistant, seawater-corrosion-resistant, and thermally conductive composite material. Utility Model Content

[0005] The purpose of this invention is to provide a seawater corrosion resistance testing device for chemically resistant, seawater-resistant, and thermally conductive composite materials, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A seawater corrosion resistant and thermally conductive composite material seawater corrosion resistance testing device includes a transparent observation tube. An inner support ring is fixedly installed on the inner wall of the top of the transparent observation tube. A mounting ring is mounted on the inner support ring. A central beam is fixedly installed on the inner annular side of the mounting ring. A perforated plate is fixedly installed between the central beam and the mounting ring. A vertically arranged central rod is detachably installed at the center of the bottom surface of the central beam. A transparent pressure plate is fixedly installed at the bottom end of the central rod. The transparent pressure plate is inserted into the transparent observation tube along the inner support ring. Multiple pressure cones are fixedly installed on the bottom surface of the transparent pressure plate.

[0007] Preferably, the length of the downward pressing cone is between 5cm and 12cm, and the downward pressing cone is conical in shape; This setting reduces the contact area with the sample, allowing for more thorough contact between the sample and seawater, which helps improve test results.

[0008] Preferably, a vertically downward-oriented central threaded sleeve is fixedly installed at the center position of the central beam, and a stud is fixedly installed at the top end of the central rod, with the stud and the central threaded sleeve being threadedly connected. This feature facilitates the installation and removal of the center rod.

[0009] Preferably, the distance between two adjacent pressing cone rods is between 3cm and 8cm, and the transparent pressing plate is provided with a plurality of overflow holes arranged in the vertical direction; This feature allows seawater to circulate on both sides of the transparent pressure plate, facilitating the downward pressure of the transparent pressure plate in the seawater.

[0010] Preferably, the perforated plate has a perforated plate structure, and two symmetrical handles are fixedly installed on the upper surface of the mounting ring.

[0011] Preferably, the bottom of the transparent observation tube is fixedly equipped with multiple support legs, the height of which is between 8cm and 12cm.

[0012] Preferably, water pipes are fixedly installed on both the bottom and top cylinders of the transparent observation tube, and anti-corrosion valves are fixedly installed on the water pipes. This feature facilitates the addition and removal of seawater.

[0013] Preferably, a top cover is hinged to the top surface of the transparent observation tube, and a sealing gasket is provided on the inner side of the top cover. When the top cover is closed, the sealing gasket is attached to the top surface of the transparent observation tube. This setting enables a sealing operation, reducing evaporation. Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves effective pressing and fixing of lightweight samples with a gravity less than buoyancy by setting a transparent pressure plate connected by a central rod inside a transparent observation tube. Multiple conical pressing cones are fixed on the bottom surface of the transparent pressure plate, which prevents the sample from floating on the water surface and affecting the integrity of the test. At the same time, the pressing cones reduce the contact area with the sample, ensuring that the sample is in full contact with the seawater, thereby ensuring the test effect and improving the test accuracy.

[0014] 2. This utility model achieves smooth flow of seawater on both sides of the transparent pressure plate by setting multiple vertical overflow holes on the transparent pressure plate and cooperating with water pipes with anti-corrosion valves at the bottom and top of the transparent observation tube. This not only does not affect the full contact between the sample and the seawater, but also facilitates the addition and discharge of seawater before and after the test. At the same time, the anti-corrosion valve can prevent seawater from corroding the pipeline, thereby maintaining a stable test environment and extending the service life of the device.

[0015] 3. This utility model achieves convenient loading and unloading of the central rod and the transparent lower pressure plate by setting a central beam and a perforated plate inside the mounting ring, with the central beam threaded to the stud at the top of the central rod via a central threaded sleeve, and a handle installed on the mounting ring and a top cover with a sealing gasket hinged to the top of the transparent observation tube.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please see Figures 1-3This utility model provides a technical solution: a seawater corrosion resistant and seawater-conducting thermally conductive composite material seawater corrosion testing device, including a transparent observation tube 1. An inner support ring 10 is fixedly installed on the inner wall of the top of the transparent observation tube 1. A mounting ring 2 is mounted on the inner support ring 10. A central beam 20 is fixedly installed on the inner annular side of the mounting ring 2. A perforated plate 21 is fixedly installed between the central beam 20 and the mounting ring 2. A vertically arranged central rod 30 is detachably installed at the center of the bottom surface of the central beam 20. A transparent pressure plate 3 is fixedly installed at the bottom end of the central rod 30. The disc 3 is inserted downwards into the transparent observation tube 1 along the inner support ring 10. The outer diameter of the transparent pressure disc 3 is smaller than the inner diameter of the inner support ring 10, so that the transparent pressure disc 3 can be removed normally. Multiple pressure cones 33 are fixedly installed on the bottom surface of the transparent pressure disc 3. The length of the pressure cones 33 is between 5cm and 12cm. The pressure cones 33 are conical, so that lightweight samples with a weight less than buoyancy can be held in place by the pressure cones 33 and immersed in seawater. The conical design reduces the contact area with the sample, ensuring that the sample is in full contact with the seawater, thus solving the problem of lightweight samples floating in traditional devices.

[0018] In this embodiment, a vertically downward-oriented central threaded sleeve 23 is fixedly installed at the center position of the central beam 20, and a stud 31 is fixedly installed at the top of the central rod 30. The stud 31 and the central threaded sleeve 23 are threadedly connected, so that the central rod 30 and the transparent pressure plate 3 can be easily installed and removed.

[0019] Specifically, the distance between two adjacent pressing cones 33 is between 3cm and 8cm, enabling the pressing cones 33 to perform pressing and immersion operations on samples of various sizes; the transparent pressing plate 3 is provided with multiple overflow holes 32 arranged vertically, so that seawater can flow smoothly on the upper and lower sides of the transparent pressing plate 3, avoiding the difficulty of pushing due to water pressure resistance during pressing, ensuring that the transparent pressing plate 3 is pressed down smoothly to the designated position, and ensuring the smooth progress of the test process.

[0020] Furthermore, the perforated plate 21 has a perforated plate structure, which facilitates the addition of the required materials into the transparent observation tube 1 along the perforated plate 21 when needed; two symmetrical handles 22 are fixedly installed on the upper surface of the mounting ring 2, which make it easy to lift the mounting ring 2 to place or remove samples, thus improving the operational flexibility of the device.

[0021] like Figure 2 As shown, multiple support legs 11 are fixedly installed at the bottom of the transparent observation tube 1. The height of the support legs 11 is between 8cm and 12cm, so that the multiple support legs 11 can stably support the operation.

[0022] like Figure 2As shown, water pipes 12 are fixedly installed on both the bottom and top cylinders of the transparent observation tube 1, and anti-corrosion valves 13 are fixedly installed on the water pipes 12 to facilitate the addition and discharge of seawater.

[0023] like Figure 1 As shown, a top cover 14 is hinged to the top surface of the transparent observation tube 1. A sealing gasket 141 is provided on the inner side of the top cover 14. After the top cover 14 is closed, the sealing gasket 141 adheres to the top surface of the transparent observation tube 1, reducing the evaporation of water in the seawater, maintaining the stability of the seawater concentration in the test environment, and avoiding the impact of water loss on the test accuracy. At the same time, the transparent observation tube 1 facilitates real-time observation of the corrosion status of the sample.

[0024] When using the seawater corrosion resistance testing device for chemically resistant, seawater-resistant, and thermally conductive composite materials of this utility model, open the top cover 14 of the transparent observation tube 1, inject seawater into the tube through the water pipe 12 with the anti-corrosion valve 13 on the top, and close the anti-corrosion valve 13 after reaching the appropriate liquid level; hold the handle 22 on the mounting ring 2, remove the mounting ring 2 from the inner support ring 10, and put the composite material sample to be tested into the seawater in the transparent observation tube 1. Next, the transparent pressure plate 3 is installed by threading the stud 31 at the top of the central rod 30 to the central threaded sleeve 23 on the central beam 20; the mounting ring 2 is placed back into the inner support ring 10, the transparent pressure plate 3 is inserted into the cylinder, the conical pressure cone rod 33 on the bottom surface presses against the sample, so that it is completely immersed in seawater, the overflow hole 32 ensures the flow of seawater from top to bottom, the top cover 14 is closed, and the sealing gasket 141 reduces water evaporation; During the test, the corrosion status of the sample is observed in real time through the transparent observation tube 1. When it is necessary to add a regulator, open the top cover 14 and put it in through the mesh plate 21. After the test, open the anti-corrosion valve 13 of the bottom water pipe 12 to drain the seawater, hold the handle 22 to remove the mounting ring 2, take out the sample, and complete the test.
