Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically a cable longitudinal water tightness testing device. Background Technology

[0002] A cable is an electrical wiring device used to transmit power or signals. It consists of one or more conductors, an insulation layer, and other protective layers, designed to transmit electrical energy or data safely and efficiently. The conductors are usually made of copper or aluminum, which can carry current. The insulation layer, also known as insulating material or insulating layer, is used to isolate the conductor and prevent current leakage or short circuits. The outer protective layer of the cable is used to protect against mechanical damage, chemical corrosion, and environmental impacts. Depending on their application, cables can be classified into power cables, communication cables, and control cables. Power cables are mainly used to transmit and distribute large amounts of electricity, communication cables are used for telephone, network, and television signal transmission, and control cables are used to transmit control signals.

[0028] See Figure 6Initially, the liquid-making mechanism 5 employs two sets of liquid-making structures. The main components are a first support platform 501, a first stirring chamber 502, a first mounting frame 503, a first drive motor 504, a first stirring rod 505, a second support platform 510, a second stirring chamber 511, a second mounting frame 512, a second drive motor 513, and a second stirring rod 514. Before activation, the first drive motor 504, the first liquid pump 506, the first solenoid valve 508, the second drive motor 513, the second liquid pump 515, and the second solenoid valve 517 need to be powered and connected to the control terminal. The first stirring chamber 502 is selected to produce acidic water. Acid and water are filled into the first stirring chamber 502. The first drive motor 504 is started, driving the first stirring rod 505 to rotate at high speed, rapidly mixing the acid and water to obtain acidic water. Water: At this time, the first liquid pump 506 is started to draw acidic water, and the acidic water is injected into the first test chamber 1 and the second test chamber 2 by switching the first solenoid valve 508. The acidic water is used to rinse the cable body 7 to perform an acidic water test on the cable body 7. Then, the second stirring chamber 511 is selected to produce alkaline water. Alkaline solution and water are filled into the second stirring chamber 511. The second drive motor 513 is started to drive the second stirring rod 514 to rotate at high speed, quickly mixing the alkaline solution and water to obtain alkaline water. At this time, the second liquid pump 515 is started to draw alkaline water, and the alkaline water is injected into the third test chamber 3 and the fourth test chamber 4 by switching the second solenoid valve 517. The alkaline water is used to rinse the cable body 7 inside the third test chamber 3 and the fourth test chamber 4 to perform an alkaline water test on the cable body 7.

[0029] Considering the influence of the installation environment on the cable body 7, especially the impact of acidic and alkaline substances in the installation environment on the cable body 7, the liquid preparation mechanism 5 adopts two sets of liquid preparation structures, which can quickly and separately produce alkaline water and acidic water. This allows for variable testing of the cable body 7. Unlike traditional ordinary water testing operations, the alkaline and acidic water prepared by the liquid preparation mechanism 5 can measure the acid and alkali resistance of the cable body 7, obtaining more accurate measurement data. In addition, among the first test chamber 1, the second test chamber 2, the third test chamber 3, and the fourth test chamber 4, the first test chamber 1 and the second test chamber 2 can test two different sets of cable bodies 7 at the same time, while the third test chamber 3 and the fourth test chamber 4 can test two other sets of cable bodies 7 at the same time. This allows for testing four sets of cable body 7 data at once, effectively improving the efficiency of testing the cable body 7.

[0030] The positioning mechanism 6 includes a first insert plate 601, a first slot 602, a first pressure plate 603, a first frame 604, a first screw 605, a sealing cover 611, and a limiting baffle 612. The first slot 602 is provided at the front end of the first test chamber 1. The first insert plate 601 is slidably connected inside the first slot 602. The first pressure plate 603 is fixedly installed at the rear end of the first insert plate 601. The first frame 604 is provided on the outer side of the first pressure plate 603. The first screw 605 is threadedly connected to the middle of the first frame 604. A first screw 605 is installed in the middle of the first test chamber 1. The sealing cover 611, the middle of the first test chamber 1 is equipped with a limit baffle 612, the positioning mechanism 6 also includes a second insert plate 606, a second slot 607, a second pressure plate 608, a second frame 609 and a second screw 610. The rear end of the first test chamber 1 is provided with a second slot 607, the second insert plate 606 is slidably connected inside the second slot 607, the front end of the second insert plate 606 is fixedly installed with a second pressure plate 608, the outer side of the second pressure plate 608 is provided with a second frame 609, and the middle of the second frame 609 is threadedly connected with a second screw 610.

[0031] See Figure 7 The positioning mechanism 6 is activated to fix the cable body 7 in the first test chamber 1, the second test chamber 2, the third test chamber 3 and the fourth test chamber 4. First, the cable body 7 is placed in the first test chamber 1. The first insert plate 601 and the second insert plate 606 are pressed down to fix the front and rear ends of the cable body 7 in the middle of the first test chamber 1. Then, the first screw 605 is turned down to press down the first insert plate 601 and the first pressure plate 603 to stably clamp the cable body 7. Next, the second screw 610 is turned down to press down the second insert plate 606 and the second pressure plate 608 to stably clamp the cable body 7.

[0032] The positioning mechanism 6 is installed on the first test chamber 1, the second test chamber 2, the third test chamber 3 and the fourth test chamber 4. It can quickly install the cable body 7 in the designated test chamber, so that the cable body 7 is stably installed in the test chamber, thereby ensuring the test stability of the test chamber.

[0033] The working principle of this utility model is as follows: First, acidic and alkaline water are prepared by the first stirring chamber 502 and the second stirring chamber 511 in the liquid preparation mechanism 5, respectively. In the first stirring chamber 502, acid and water are filled and stirred to produce acidic water; in the second stirring chamber 511, alkaline and water are filled and stirred to produce alkaline water. Then, these acidic and alkaline waters are drawn in by the first liquid pump 506 and the second liquid pump 515, respectively, and flow into the first test chamber 1, the second test chamber 2, the third test chamber 3, and the fourth test chamber 4 under the control of the electronic control valve. During this process, the cable body 7 is positioned by the positioning mechanism 6. Fixed inside the test chamber, the cable body 7 is secured within the chamber by the sliding of the insert plate and the pressure plate, as well as the turning of the screw. Subsequently, acidic and alkaline water are used to rinse the cable body 7, simulating the acid and alkaline environments that the cable may encounter in actual applications, in order to test the sealing performance of the cable body 7. At the same time, since the first test chamber 1, the second test chamber 2, the third test chamber 3, and the fourth test chamber 4 can test different cable bodies 7 separately, the testing efficiency is improved. This testing device not only overcomes the limitation of traditional testing methods that can only perform water immersion tests, but also provides sealing performance data of the cable body 7 under acid and alkaline environments.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
