Description

Technical Field

[0001] The utility model belongs to the technical field of deep sea high pressure corrosion detection, in particular to an electrode device for deep sea high pressure corrosion detection. Background Art

[0002] With the increase of water depth, the corrosion type and corrosion rate of materials have undergone significant changes. However, deep-sea natural environment corrosion tests have many difficulties, such as complex systems, high costs, long cycles, and difficult to reliably recover samples and equipment. At the same time, the factors affecting corrosion in real sea environments are very complex and their respective effects are difficult to distinguish. Therefore, in order to better understand the corrosion behavior of materials in deep-sea environments, many researchers have begun to study the effects of single factors on material corrosion by simulating environments in laboratories.

[0003] Deep-sea high-pressure corrosion equipment is a key device for simulating deep sea. It can simulate the deep-sea environment of 3500 to 7000 meters. In this environment, the material does not corrode instantly, but needs to maintain pressure for 7 to 15 days. However, in existing high-pressure corrosion equipment, most of the detection electrodes are designed as a single sample structure, and only one sample can be tested in each test. This leads to frequent disassembly of the kettle, which can easily cause dents on the kettle cover and the kettle body, poor pressure maintenance, unstable data, and shortened equipment life. At the same time, the detection efficiency is also low. Utility Model Content

[0004] Based on the above background, the purpose of the utility model is to provide an electrode device for deep-sea high-pressure corrosion detection, which can reduce the frequency of dismantling the kettle, improve the detection efficiency and detection accuracy, and extend the service life of the equipment.

[0005] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0009] Furthermore, it also includes a sealing portion, which is used to cover part of the sample and expose the detection end of the sample, and the detection wire is used to be connected to the detection end of the sample.

[0010] Furthermore, it also includes a supporting structure, which is detachably connected to the electrode body and is used to support each of the samples.

[0011] Furthermore, the supporting structure includes a rod body, and a card body and a support assembly spaced apart on the rod body, the card body is snap-connected to the rod body, the support assembly is at least partially located on one side of the opening and in the middle of each of the detection wires, and the support assembly is used to support each of the samples.

[0012] Furthermore, a first nut and a second nut are threadedly connected to the electrode body, a slot is provided between the first nut and the second nut, the card body is inserted into the slot, and the first nut is located below the second nut and can be rotated up and down and adjusted along the length direction of the electrode body.

[0013] Furthermore, the support assembly includes a connecting member, a support rod and a plurality of support rods, the connecting member is connected to the rod body, and one end extends to the bottom of the opening, the support rod is connected to the connecting member, all the support rods are connected to the support rod at circumferential intervals, and the support rods are used to support the corresponding samples.

[0014] Furthermore, the supporting structure also includes reinforcing ribs, and the reinforcing ribs are connected between the connecting member and the rod body.

[0015] Furthermore, the supporting structure includes a guide ring, which is connected to the rod body and sleeved outside the electrode body, and the guide ring can move along the length direction of the electrode body.

[0016] The utility model has the following beneficial effects:

[0017] (1) A lead channel is provided inside the electrode body to accommodate multiple bundles of detection wires, so that one end of each detection wire passes out of the opening, so that each detection wire is connected to a different sample, thereby realizing corrosion detection of multiple samples at the same time. At the same time, a sealing plug is introduced to seal the opening, ensuring that the electrode device will not release pressure from the opening when being tested in the autoclave, achieving effective pressure maintenance, and providing sealing conditions for realizing simultaneous detection of multiple samples.

[0035] In one embodiment, please refer to Figures 1 to 7 The present application provides an electrode device 100 for deep-sea high-pressure corrosion detection, comprising: an electrode body 10, two or more detection wires 20 and a sealing plug 30. The electrode body 10 has a lead channel 11 extending axially inside, and one end of the electrode body 10 has an opening 12 connected to the lead channel 11, and the two or more detection wires 20 are all inserted into the lead channel 11 and pass through the opening 12. One end of each detection wire 20 passing through the opening 12 is used to connect with the corresponding sample 200; the sealing plug 30 is blocked in the opening 12, and each detection wire 20 passes through the sealing plug 30.

[0036] The electrode device 100 described above is provided with a lead channel 11 inside the electrode body 10 to accommodate multiple bundles of detection wires 20, so that one end of each detection wire 20 passes through the opening 12, so that each detection wire 20 is connected to a different sample 200, thereby realizing corrosion detection of multiple samples 200 at the same time. At the same time, a sealing plug 30 is introduced to seal the opening 12, ensuring that the electrode device 100 will not release pressure from the opening 12 when being tested in the autoclave 300, achieving effective pressure maintenance, and providing sealing conditions for realizing simultaneous detection of multiple samples 200. In this way, the electrode device 100 of the present application can realize simultaneous detection of multiple samples 200, reduce the frequency of disassembling the autoclave, improve detection efficiency and detection accuracy, and extend the service life of the equipment.

[0037] It should be explained that in high-voltage corrosion detection, the sample 200 needs to be placed in the autoclave 300 together with the electrode device 100, and the single factor simulated in the autoclave 300 will drive the surface of the sample 200 to corrode. When the surface of the sample 200 corrodes, the performance parameters of its surface also change accordingly, such as: potential, etc. At this time, the detection wire 20 electrically connected to the sample 200 will feed back the changed signal to the background processor to obtain relevant experimental data. Since the corrosion principle of the sample 200 and the current connection between the detection wire 20 and the background processor are not the objects of improvement of this application, they are not described here in detail, and you can directly refer to the existing literature.

[0038] The detection wire 20 passes through the sealing plug 30 from the opening 12. This can be achieved by drilling a hole in the sealing plug 30 and passing the detection wire 20 through the hole; after passing through, the detection wire 20 and the sealing plug 30 are bonded and sealed with sealing glue; or, the detection wire 20 can be passed through the opening 12 first, and then one end of the electrode body 10 can be inserted into a beaker filled with epoxy resin solution for sealing.

[0039] Optionally, there are various ways to connect the detection wire 20 and the sample 200, such as welding, clamping, binding, etc.

[0040] In addition, since a plurality of samples 200 are connected to one end of the electrode body 10, the lid of the autoclave 300 can be removed during the detection process; then the end of the electrode body 10 that is not connected to the sample 200 is inserted into the lid; after insertion, each detection wire 20 is connected to the corresponding sample 200 in turn; after connection, the lid and the sample 200 are transferred to the autoclave 300 together and sealed.

[0041] For further information, please refer to Figure 4 The sealing plug 30 includes a bottom 31 and an embedding portion 32 provided on the bottom 31. The embedding portion 32 is used to be embedded in the opening 12, and each detection wire 20 passes through the bottom 31. It can be seen that the sealing plug 30 is designed to have a bottom 31 and an embedding portion 32. The embedding portion 32 is embedded in the opening 12 to achieve sealing of the opening 12. The bottom 31 is provided for the detection wire 20 to pass through. In this way, while the detection wire 20 passes through, the sealing performance of the electrode device 100 is improved.

[0042] It needs to be explained that in Figure 4 Only a schematic diagram of the structure of the sealing plug 30 is shown. When the sealing plug 30 is directly formed by epoxy resin solution, the embedded part 32 and the bottom 31 have no hole structure, and the part is directly bonded to the outer periphery of the detection wire 20. Figure 4 No pore structure will appear in the

[0043] For further information, please refer to Figure 4 The sealing plug 30 further includes a sleeve portion 33, which is disposed on the bottom 31 and is disposed around the outer periphery of the embedded portion 32. A slot 34 is formed between the sleeve portion 33 and the embedded portion 32. The sleeve portion 33 is sleeved outside one end of the electrode body 10, and one end of the electrode body 10 is inserted into the slot 34. It can be seen that the sleeve portion 33 is disposed on the outer periphery of the embedded portion 32 and sleeved outside the electrode body 10, thereby increasing the bonding strength and improving the sealing effect; at the same time, a slot 34 is formed between the sleeve portion 33 and the embedded portion 32, into which one end of the electrode body 10 can be inserted, thereby further increasing the bonding strength between the sealing plug 30 and the electrode body 10.

[0044] Specifically, the bottom portion 31 , the sleeve portion 33 and the embedding portion 32 are an integrated structure.

[0045] In one embodiment, please refer to Figure 1 , further comprising a sealing portion 40, the sealing portion 40 is used to cover a portion of the sample 200 and expose the detection end 210 of the sample 200, and the detection wire 20 is used to connect with the detection end 210 of the sample 200. It can be seen that the sealing portion 40 protects the portion that does not need to be tested.

[0046] The sealing part 40 may be a resin structure, for example, the part of the sample 200 that does not need to be corroded is inserted into an epoxy resin solution so as to be wrapped and protected.

[0047] In one embodiment, please refer to Figure 5 and Figure 6 , and also includes a supporting structure 50, which is detachably connected to the electrode body 10 and is used to support each sample 200. It can be seen that since the electrode device 100 is connected to multiple samples 200 at the same time through multiple detection wires 20, it is difficult to carry the samples 200 during the transfer of the autoclave 300 due to the large number of samples 200, and the wire harness is prone to breakage. For this reason, a supporting structure 50 is connected to the electrode body 10, and each sample 200 is supported by the supporting structure 50, so that the transfer of the sample 200 is more convenient, which is conducive to improving the convenience and reliability of detection.

[0048] For further information, please refer to Figure 7 The supporting structure 50 includes a rod body 51, a card body 52 and a support assembly 53 which are arranged on the rod body 51 at intervals. The card body 52 is clamped with the rod body 51. The support assembly 53 is at least partially located on one side of the opening 12 and in the middle of each detection wire 20. The support assembly 53 is used to support each sample 200. It can be seen that the card body 52 is used to facilitate the fixing of the supporting structure 50 on the electrode body 10; at the same time, the support assembly 53 is used to facilitate the effective support of each sample 200, so that the experimenter can easily transfer the sample 200.

[0049] For further information, please refer to Figure 7 A first nut 13 and a second nut 14 are screwed on the electrode body 10, and a slot 15 is provided between the first nut 13 and the second nut 14. The card body 52 is inserted into the slot 15, and the first nut 13 is located below the second nut 14 and can be rotated up and down along the length direction of the electrode body 10 for adjustment.

[0050] It can be seen that a card slot 15 is formed on the electrode body 10 by using the first nut 13 and the second nut 14, which facilitates the stable card connection of the card body 52 and improves the assembly efficiency of the device; at the same time, the first nut 13 is located below the second nut 14 and can be rotated and adjusted along the length direction of the electrode body 10. Therefore, the position of the card body 52 on the electrode body 10 can be driven by the first nut 13, and then the position of the support assembly 53 can be adjusted, so as to adapt to the support of samples 200 of different sizes and improve the applicability of the supporting structure 50.

[0051] In one embodiment, please refer to Figure 7 The supporting assembly 53 includes a connecting member 531, a supporting rod 532 and a plurality of supporting rods 533. The connecting member 531 is connected to the rod body 51, and one end thereof extends to the bottom of the opening 12. The supporting rod 532 is connected to the connecting member 531. All supporting rods 533 are connected to the supporting rod 532 at circumferential intervals. The supporting rods 533 are used to support the corresponding samples 200.

[0052] To facilitate the connection between the connecting member 531 and the supporting rod 532, a circular platform 534 can be set on the end of the connecting member 531 away from the rod body 51, and the supporting rod 532 is connected to the circular platform 534; similarly, a circular support platform 535 can be set at one end of the supporting rod 533, and the support platform 535 is used to support the sample 200.

[0053] For further information, please refer to Figure 7 The supporting structure 50 further includes a reinforcing rib 54, and the reinforcing rib 54 is connected between the connecting member 531 and the rod body 51. It can be seen that the overall structural strength of the supporting structure 50 is improved, thereby improving the stability of the structure.

[0054] For further information, please refer to Figure 7 The supporting structure 50 includes a guide ring 55, which is connected to the rod body 51 and sleeved outside the electrode body 10. The guide ring 55 can move along the length direction of the electrode body 10. In this way, the supporting structure 50 can be adjusted up and down along the length direction of the electrode body 10 through the guide ring 55, so that the supporting assembly 53 can better support the sample 200.

[0055] It should be explained that both the card body and the guide ring can be set to a semicircular ring structure, which is convenient for being clamped on the outside of the electrode body.

[0056] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
