Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a test system for 535KV submarine cable perforation. Background Technology

[0002] 535kV submarine cables represent cutting-edge technology in the field of high-voltage direct current transmission, playing a crucial role, especially in long-distance offshore wind power grid connection and cross-sea interconnection projects. Submarine cable perforation testing is a key test for evaluating the mechanical connection strength between the cable and the connector. It is mainly used to verify the reliability of the cable end sealing assembly under tensile force, ensuring its stable operation in complex marine environments. The purpose of the test is to evaluate the connection strength and predict the fault threshold.

[0003] However, when performing pull-out tests on cables and connectors, most testing devices are now fixed with bolts. During connection, the connection surface affects the uneven force distribution under tension. Furthermore, because multiple sets of test results need to be compared, it is impossible to guarantee that the fixing pressure is equal, which greatly affects the accuracy of the actual test results. Summary of the Invention

[0004] This invention provides a 535KV submarine cable pull-out test system, which can effectively solve the problems mentioned in the background art. Currently, when performing pull-out tests on cables and connectors, the test devices are mostly fixed with bolts. During connection, the connection surface affects the uneven force during traction. Furthermore, because multiple sets of test results need to be compared, it is impossible to guarantee that the fixing pressure is equal, which greatly affects the accuracy of the actual test results.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A 535kV submarine cable perforation testing system includes an integrated support frame.

[0009] Furthermore, the traction operating frame is slidably installed inside the fixed-limit sliding hole.

[0010] Furthermore, the outer diameter of the limiting sleeve is equal to the outer diameter of the combined threaded cover, and the side end of the clamping operation tube is fitted and connected to the side end of the limiting sleeve and the traction fixing sleeve.

[0011] Furthermore, one end of the clamping air pump is connected to one end of the clamping operation tube via an adapter. The input ends of the reciprocating electric slide rail, traction motor, tension detector, and clamping air pump are all electrically connected to the output end of the external controller. The signal output end of the tension detector is electrically connected to the signal input end of the external controller, and the input end of the external controller is electrically connected to the output end of the external power supply.

[0012] Furthermore, a fixed-movement component is provided on the side of the integrated support frame. The fixed-movement component includes a movable operating frame, which is located at the bottom of the integrated support frame and the reciprocating support frame. A movable operating wheel is rotatably connected to the side of the movable operating frame. Several pressure-positioning electric actuators are installed on the inner bottom of the integrated support frame and the reciprocating support frame. A connecting suction cup is provided at the bottom of the pressure-positioning electric actuator. A negative pressure treatment pipe is connected to the side of the connecting suction cup via an adapter. An operating air pump is installed on the inner bottom of the reciprocating support frame via a motor base. Correction electric slide rails are embedded at both ends of the reciprocating support frame. A correction operating plate is installed at one end of the correction electric slide rail via a slide rail seat. Several inclined bracing electric actuators are installed at the top of the correction operating plate. An inclined bracing arc plate is installed at one end of each of the inclined bracing electric actuators.

[0013] Furthermore, a number of rising electric push rods are installed at the top center of the integrated support frame, and a rising arc plate is installed at one end of each of the rising electric push rods. The negative pressure treatment pipe is installed through the integrated support frame and the side end of the reciprocating support frame, and one end of the negative pressure treatment pipe is connected to one end of the operating air pump through an adapter.

[0014] Furthermore, the correction operation plate is slidably mounted on the side end of the reciprocating support frame, and the input ends of the pressure electric push rod, the operation air pump, the correction electric slide rail, the inclined brace electric push rod, and the rising electric push rod are all electrically connected to the output end of the external controller.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. Equipped with a traction support assembly, the reciprocating support frame is moved via a reciprocating electric slide rail, changing the distance between the reciprocating support frame and the integrated support frame. The equipment position is adjusted according to the cable and connector dimensions to ensure the stability of the alignment combination. The cable and connector are fitted together using a fixed compression airbag and a traction compression airbag. Air is injected into the fixed compression airbag and traction compression airbag positions using a clamping air pump and clamping operating tube. By controlling the pressure, the uniformity of multiple test combination connections is ensured. At the same time, high pressure is used to press the airbag against the side end of the connector, fully enclosing the contact point to ensure the stability of the connection combination and avoid connection instability during traction pull-out testing. This ensures the stability of the connection between the equipment and the cable, avoiding test errors caused by connection instability, thereby improving the accuracy and reliability of the test. By controlling the airbag, consistent pressure and connection force can be maintained in multiple test combinations, improving the stability of the testing process.

[0016] 2. The traction motor and traction screw drive the traction operating frame, traction screw, traction operating cover, traction fixing sleeve, traction pressing airbag, and one side of the cable to move synchronously. This, combined with the fixing pressing airbag, limit clamp sleeve, combined threaded cover, fixing screw, and tensile strength detector, secures one side of the cable. This continuous movement and pressure application, along with testing, achieves cable break-through strength measurement at the cable's end. The fully enclosed and controllable pressure fixation prevents uneven force distribution and partial separation of the cable and connectors due to uneven force distribution at a single fixing point, effectively improving test accuracy. Furthermore, the direct fitting connection reduces the labor intensity of repeated installations and increases testing speed. Uniform pressure and precise control prevent cable deviation or separation during testing due to uneven force distribution, ensuring accurate test results. Simultaneously, it reduces manual operation, alleviates workload, and improves testing efficiency.

[0017] 3. Equipped with a fixed-position component, the entire system is moved via a movable operating frame and wheels, enabling rapid adjustment of the equipment's position. A pressure-positioning electric actuator raises and lowers the connecting suction cups. By contacting the suction cups with the ground, a negative pressure environment is created between the suction cups and the ground using an operating air pump and negative pressure treatment pipe. This negative pressure fixation positions the integrated support frame and reciprocating support frame. The pressure-positioning electric actuator further corrects the overall horizontal support, ensuring the overall support and testing levelness. This allows the system to move flexibly and position quickly, ensuring the equipment remains in the correct position during testing. Simultaneously, the negative pressure adsorption method ensures the stability and support accuracy of the equipment, making cable testing more precise and efficient.

[0018] 4. The correction operation plate is moved by the correction electric slide rail to adjust the position of the inclined support arc plate. The inclined support arc plate is raised and lowered by the inclined support electric push rod, and the rising arc plate is raised and lowered by the rising electric push rod. The support limit position of the cable and the side end is adjusted according to the diameter of the cable to prevent the cable from swinging and detaching during the traction process. At the same time, the bottom of the cable is restricted to prevent it from collapsing downward in the early stage of traction, ensuring the safety of the experimental environment. It also facilitates the subsequent handling of the cable, reduces the labor intensity of the staff, and ensures that the cable remains stable throughout the traction process and will not shift or collapse due to improper fixation. This not only improves the safety of the experiment, but also makes the subsequent cable handling more convenient for the staff and reduces the labor intensity.

[0019] In summary, by cooperating with the traction support assembly and the fixed displacement assembly, and through multiple sets of fixed connections, the stability of the support during equipment traction and the stability of the connection with the cable during traction are ensured. Furthermore, by adjusting and limiting the support, the influence of the external environment on the test data and results during the cable detachment test is reduced, thereby improving the accuracy of the test.

[0025] The reciprocating support frame 202 and the integrated support frame 1 are slidably fitted together. The longitudinal section of both the reciprocating support frame 202 and the integrated support frame 1 is U-shaped. The traction screw 204 is rotatably installed on the side of the reciprocating support frame 202 to achieve support positioning and movement positioning cooperation.

[0027] One end of the integrated support frame 1 is welded with a limiting and fixing rod 207.

A tension detector 208 is installed at one end of the limiting and fixing rod 207.

[0028] A fixing screw 209 is installed at one end of the tensile tester 208, and a combined threaded cap 210 is connected to the side end of the fixing screw 209 by thread.

[0029] One of the combined threaded caps 210 is rotatably connected to a limiting sleeve 211 on its side end. The outer diameter of the limiting sleeve 211 is equal to the outer diameter of the combined threaded cap 210, thus achieving a closed connection. A fixed pressure airbag 212 is installed inside the limiting sleeve 211.

[0030] A traction screw 213 is installed at one end of the traction operating frame 206, and a traction operating cover 214 is threadedly connected to the side end of the traction screw 213.

[0032] Both the integrated support frame 1 and the traction operation frame 206 have a clamping air pump 217 mounted on one end via a motor mount.

[0035] The input terminal of the external controller is electrically connected to the output terminal of the external power supply.

[0036] The integrated support frame 1 is equipped with a fixed displacement component 3 on its side.

[0037] The fixed-position component 3 includes a movable operating frame 301, a movable operating wheel 302, a pressure electric actuator 303, a connecting suction cup 304, a negative pressure treatment pipe 305, an operating air pump 306, a correction electric slide rail 307, a correction operating plate 308, a diagonal brace electric actuator 309, a diagonal brace arc plate 310, a rising electric actuator 311, and a rising arc plate 312.

[0038] A movable operating frame 301 is installed at the bottom of the integrated support frame 1 and the reciprocating support frame 202, and a movable operating wheel 302 is rotatably connected to the side of the movable operating frame 301.

[0039] Several pressure-positioning electric actuators 303 are equidistantly installed on the inner bottom of the integrated support frame 1 and the reciprocating support frame 202, and a connecting suction cup 304 is provided at the bottom of the pressure-positioning electric actuator 303.

[0040] The suction cup 304 is connected to a negative pressure treatment pipe 305 via an adapter. The negative pressure treatment pipe 305 is installed through the integrated support frame 1 and the reciprocating support frame 202. One end of the negative pressure treatment pipe 305 is connected to one end of the operating air pump 306 via an adapter to achieve steady air intake and exhaust treatment and ensure the overall fixation effect. The operating air pump 306 is installed on the bottom inner side of the reciprocating support frame 202 via a motor mount.

[0041] Both ends of the reciprocating support frame 202 are embedded with correction electric slide rails 307. One end of the correction electric slide rail 307 is equipped with a correction operation plate 308 through a slide rail seat. The correction operation plate 308 is slidably installed on the side of the reciprocating support frame 202 to achieve positioning and sliding support.

[0042] Several inclined electric actuators 309 are equidistantly embedded at the top of the correction operation panel 308, and an inclined arc plate 310 is installed at one end of each inclined electric actuator 309.

[0043] Several lifting electric push rods 311 are equidistantly installed at the top center of the integrated support frame 1, and one end of each of the lifting electric push rods 311 is equipped with a lifting arc plate 312.

[0044] To ensure stable operation of the equipment, the input ends of the pressure-positioning electric actuator 303, the operating air pump 306, the correction electric slide rail 307, the inclined support electric actuator 309, and the rising electric actuator 311 are all electrically connected to the output end of the external controller.

[0045] The working principle and usage process of this invention are as follows: When performing a cable piercing test, the integrated support frame 1 and the reciprocating support frame 202 are pushed, and the moving operating frame 301 and the moving operating wheels 302 are used to move the equipment and change the operating position, which facilitates quick position adjustment. In addition, the reciprocating electric slide rail 201 moves the reciprocating support frame 202 along the integrated support frame 1, changing the distance between the reciprocating support frame 202 and the integrated support frame 1. After the distance is adjusted, the pressure-positioning electric push rod 303 moves the connecting suction cup 304 down, so that the connecting suction cup 304 is attached to the ground. At this time, the air pump 306 and the negative pressure treatment pipe 305 are used to extract air from the position of the connecting suction cup 304. Through the negative pressure environment, the connecting suction cup 304 is fixed to the ground, thereby positioning the integrated support frame 1 and the reciprocating support frame 202. The pressure-positioning electric push rod 303 is used to correct the overall horizontal support, ensuring the overall levelness of the support.

[0046] After the equipment is fixed, the correction operation plate 308 is moved along the reciprocating support frame 202 by the correction electric slide rail 307, so that the side end of the inclined support arc plate 310 is attached to the side end of the rising arc plate 312. At this time, after the staff has assembled the prepared cable and connector, one end of the cable and connector assembly is inserted into the inside of the fixed compression airbag 212, and the other end is inserted into the inside of the traction compression airbag 216. Air is injected into the fixed compression airbag 212 and the traction compression airbag 216 through the clamping air pump 217 and the clamping operation tube 218. The high pressure is used to press the airbag and the side end of the connector together, and the contact position is fully wrapped to ensure the stability of the connection assembly and avoid the situation where the connection is unstable during the traction pull-out test, which would affect the test results.

[0047] After assembly, the inclined support electric actuator 309 drives the inclined support arc plate 310 to rise, and the rising electric actuator 311 drives the rising arc plate 312 to rise, pushing the cable to move between the limit clamp sleeve 211 and the traction fixing sleeve 215, thereby supporting its bottom and preventing it from collapsing downwards. The traction motor 203 drives the traction screw 204 to rotate, and the traction screw 204 drives the traction operating frame 206 to move along the traction fixing column 205. The traction operating frame 206 drives the traction screw 213, the traction operating cover 214, the traction fixing sleeve 215, and the traction... The compression airbag 216 and the cable connection end move synchronously. During the movement, the cable is first straightened. When straightened, the cable will pull the compression airbag 212, the limiting clip sleeve 211, the combined threaded cover 210, the fixing screw 209, the tension detector 208 and the limiting fixing rod 207 located at the position of the integrated support frame 1. Since the limiting fixing rod 207 is a welded assembly, the tension detector 208 is fixed and does not move. During the traction process, it is continuously subjected to the tension brought by the movement, thereby continuously detecting the tension strength and realizing the cable hole strength side end.
