Description

Technical Field

[0001] This utility model relates to the technical field of adhesive testing equipment, and in particular to a tooling for testing the waterproof performance of adhesive filling. Background Technology

[0002] In the field of marine engineering, submarine cables serve as crucial carriers for transmitting telecommunications signals and high-power electrical energy underwater, and their safe and stable operation is of paramount importance. Submarine cables typically consist of conductors and a tightly sealed waterproof adhesive layer around their outer perimeter. This waterproof adhesive layer, as the first line of defense against seawater corrosion, directly affects the cable's lifespan and transmission reliability. If the waterproof adhesive layer fails, seawater will rapidly penetrate the cable, potentially causing serious faults such as short circuits and corrosion, leading to communication outages or power transmission disruptions, resulting in significant economic losses and social impact.

[0003] To ensure the reliable operation of submarine cables in complex marine environments, testing the waterproof performance of the waterproof adhesive layer is a crucial step. However, the waterproof testing fixtures currently used are often structurally complex, requiring high assembly precision and debugging capabilities. This not only increases the manufacturing cost of the fixtures but also consumes a significant amount of time and manpower during routine maintenance and troubleshooting due to their complexity.

[0023] Reference Figures 1 to 4This application discloses a testing fixture for the waterproof performance of adhesive filling, including an outer cylinder 100, an inner cylinder 200, a top cover 300, and a bottom sealing plate 400. Both the outer cylinder 100 and the inner cylinder 200 are cylindrical structures. The outer cylinder 100 defines a receiving cavity 110. The top cover 300 is installed at the top of the outer cylinder 100, and the bottom sealing plate 400 is installed at the bottom of the outer cylinder 100. The inner cylinder 200 is installed inside the receiving cavity 110, and the axial direction of the outer cylinder 100 is parallel to the axial direction of the inner cylinder 200.

[0024] Reference Figure 2 As shown, the inner cylinder 200 has a through hole 210 axially penetrating its center, and the bottom end of the inner cylinder 200 is connected to the outer cylinder 100. To ensure the rigor of the test, this embodiment also uses an auxiliary cable 500, preferably a finished submarine cable, to simulate the actual use scenario of submarine cables to the greatest extent. The end of the auxiliary cable 500 passes through the bottom sealing plate 400 and the inner cylinder 200 and extends into the receiving cavity 110; the bottom sealing plate 400 has a through hole 410 penetrating the bottom sealing plate 400, and the auxiliary cable 500 is sealed to the through hole 410. A glue-filling space is formed between the outer peripheral wall of the auxiliary cable 500 and the inner side wall of the through hole 210. After the glue fills the glue-filling space and solidifies, a waterproof glue layer is formed. The test fixture in this embodiment is mainly used to test the waterproof effect of the waterproof glue layer.

[0025] Reference Figure 1 , Figure 2 As shown, the top cover 300 is used to seal the top of the receiving cavity 110; the top cover 300 is equipped with a water inlet 310 and a pressure port 320; after the adhesive has completely solidified to form a waterproof adhesive layer, the top cover 300 is closed, and water is injected into the receiving cavity 110 through the water inlet 310. After the water is full, the water inlet 310 is closed, and pressure is applied to the receiving cavity 110 through the pressure port 320 to the set pressure, thus realizing the waterproof test of the waterproof adhesive layer. The structure is simple, the test is convenient, and the manufacturing and maintenance costs of the test fixture are low. The set pressure can be set according to the test requirements, such as the depth required for laying the submarine cable, to inject the corresponding water pressure; that is, for waterproof adhesive layers suitable for different depths, the raw materials used to manufacture the waterproof adhesive layer will differ. The test fixture of this embodiment can test waterproof adhesive layers suitable for different pressures, and has wide applicability. The waterproof adhesive layer needs to remain at the set pressure for a set time without leakage to pass the test.

[0026] To prevent water in the containment cavity 110 from seeping out through the inside of the auxiliary cable 500 and affecting the accuracy of the test results, the end of the auxiliary cable 500 is usually sealed by installing a sealing cover or wrapping epoxy putty. The auxiliary cable 500 can be sealed at only one end that extends into the containment cavity 110, or both ends along its length can be sealed.

[0027] It is conceivable that the through hole 410 and the through hole 210 are preferably set concentrically to ensure that the thickness of the waterproof adhesive layer is uniform at all locations, so as to meet the actual use scenario; the inner cylinder 200 and the outer cylinder 100 can be set concentrically or non-concentrically, without affecting the testing of the waterproof adhesive layer.

[0028] In the embodiments of this application, reference is made to Figure 2 As shown, the bottom end of the inner cylinder 200 is preferably flush with the bottom end of the outer cylinder 100 to facilitate the installation of the bottom sealing plate 400. During the testing of the waterproof adhesive layer, in order to facilitate the observation of leakage of the waterproof adhesive layer, the bottom sealing plate 400 is preferably detachably connected to the outer cylinder 100. That is, after the adhesive has completely solidified to form a waterproof adhesive layer, the bottom sealing plate 400 can be removed, thereby facilitating the observation of leakage of the waterproof adhesive layer during the test.

[0029] It is conceivable that, referring to Figure 4 As shown, the bottom of the inner cylinder 200 can also rest on the outer cylinder 100.

[0030] To further reduce the maintenance cost of the test fixture in this embodiment, the inner cylinder 200 can be detachably connected to the outer cylinder 100, for example, by fasteners such as bolts or clips, which is not limited in this embodiment. The bottom end of the inner cylinder 200 can be connected to the outer cylinder 100, and / or the top or middle part of the inner cylinder 200 can be connected to the inner wall of the receiving cavity 110. One or more of the above connection methods can be adopted according to the actual situation to ensure the stability of the inner cylinder 200.

[0031] In the embodiments of this application, the inner cylinder 200 can be a single integrated structure or assembled from multiple structural units. A single integrated structure refers to integral molding, while an assembly from multiple structural units refers to assembly from multiple structural units by welding or fasteners. The inner cylinder 200 with a single integrated structure has higher structural strength, while the inner cylinder 200 assembled from multiple structural units is easier to disassemble and reassemble, and has lower maintenance costs.

[0032] Reference Figure 1 As shown, in the embodiments of this application, the top cover 300 is hinged to the outer cylinder 100, thereby avoiding the problem of needing to align the top of the top cover 300 with the top of the outer cylinder 100, and further improving operational efficiency. (Refer to...) Figure 1 , Figure 3 As shown, the top of the outer cylinder 100 is provided with a radially protruding ring edge 120, and the top cover 300 is connected to the ring edge 120 by multiple locking parts 350. The locking parts 350 can be bolts or other structures.

[0033] In specific embodiments of this application, reference is made to Figure 3As shown, the ring edge 120 is provided with a threaded hole. The locking component 350 includes a locking bolt 351 and a locking nut 352. The locking bolt 351 passes through the top cover 300 to be threadedly connected to the ring edge 120. The locking nut 352 is installed on the locking bolt 351 and abuts against the top cover 300 to prevent the locking bolt 351 from loosening. For easy operation by hand, the top of the locking bolt 351 is also provided with a handle structure.

[0034] In the embodiments of this application, since the waterproof adhesive layer needs to undergo a pressure test for waterproofing, a sealing ring is provided between the circumference 120 and the top cover 300. The sealing ring can be purchased from existing finished products according to actual needs, and is not limited in this embodiment.

[0035] In the embodiments of this application, reference is made to Figure 1 , Figure 2 As shown, the water inlet 310 is equipped with a water inlet valve, which is used to open and close the water inlet 310; the pressurization port 320 is used to connect to pressurization equipment, which can be purchased as a ready-made product according to actual needs; the top cover 300 is also equipped with a pressure gauge 330 and a cover opening handle 340. The pressure gauge 330 is used to observe the water pressure in the containment cavity 110 during testing, and the cover opening handle 340 facilitates the opening and closing of the top cover 300.

[0036] In the embodiments of this application, the outer cylinder 100 is preferably made of stainless steel or the like, and the inner cylinder 200 is preferably made of copper.
