Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a multifunctional aging test device for insulated cable materials. Background Technology

[0002] In the field of modern power transmission and electrical equipment, insulated cables serve as a crucial carrier for power transmission, and the durability and reliability of their materials directly affect the safety of power grid operation and the service life of equipment. With the rapid development of industries such as new energy and smart grids, higher demands are being placed on the long-term performance of insulated cables in complex environments such as high temperature, humidity, and strong radiation. Therefore, developing testing devices capable of accurately simulating various aging conditions has become a vital step in ensuring cable material quality and driving technological upgrades in the industry.

[0003] Existing aging test devices for insulated cable materials mostly employ single or combined aging environment simulations. For example, thermal aging is achieved through a heating chamber, while humidity control equipment simulates a humid and hot environment. Their working principle typically involves placing the cable sample in a sealed chamber and controlling environmental parameters such as temperature, humidity, and light to induce aging of the material under set conditions. After a certain period, the sample is removed, and its insulation resistance, tensile strength, and other performance indicators are tested to assess the degree of aging.

[0004] In existing technologies, some aging test devices have obvious defects in the sample fixing process. Traditional rigid clamping structures often use bolt fastening or spring compression, which makes it difficult to accurately control the clamping force and can easily lead to excessive local stress on the cable material, resulting in problems such as indentation, deformation, or even damage to the internal structure. Therefore, a multi-functional aging test device for insulated cable materials is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a multifunctional aging test device for insulating cable materials, including a shell 1 made of high-strength corrosion-resistant material to house internal test components and prevent external interference. A transparent door 2 is fixedly connected to the outside of the shell 1. The transparent door 2 is made of high-temperature resistant and high-strength transparent material, which allows operators to observe the aging state of the internal samples in real time without damaging the test environment. A water collection mechanism 5 is provided on the inside of the shell 1. The water collection mechanism 5 is used to collect liquids generated during the test, such as condensate or sprayed water mist in a humid and hot environment, to prevent liquid accumulation from affecting the accuracy of the test and the safety of the equipment. A fixing mechanism 6 is provided on the outside of the water collection mechanism 5. The fixing mechanism 6 is responsible for stably clamping the insulating cable material sample to ensure that the sample position is fixed during the test and to avoid test data errors caused by displacement. A swing mechanism 7 is provided on the top of the inside of the shell 1. The swing mechanism 7 realizes the swing spray of the nozzle 78 through mechanical transmission, uniformly adjusting the humidity inside the shell 1 to simulate a humid and hot aging environment.

[0033] The fixing mechanism 6 includes a cylinder 61, which provides a stable and controllable thrust to drive the subsequent structure to clamp and release the sample. The cylinder 61 is externally fixedly connected to the top of the water accumulation mechanism 5. A push plate 62 is fixedly connected to the drive end of the cylinder 61. The push plate 62 receives and transmits the linear thrust of the cylinder 61, providing power for the rotation of the connecting rotating plate 63. The outer sides of the push plate 62 are rotatably connected to the connecting rotating plate 63. The connecting rotating plate 63, the push plate 62, and the connecting rotating plate 64 form a linkage transmission structure, converting the linear motion of the push plate 62 into the rotational motion of the rotating clamp 65. The outer rotation of the connecting rotating plate 63... A connecting rotating plate 64 is connected to the rotating plate 64, which further transmits the motion. Through the lever principle, the force is amplified and evenly distributed to ensure that the clamping force of the rotating clamp 65 is uniform. The rotating clamp 65 is rotatably connected to the external of the connecting rotating plate 64. The rotating clamp 65 is used to directly contact the cable sample and clamp and release the sample through rotation. Its surface is made of flexible anti-slip material to prevent damage to the sample while ensuring a firm clamping. A limit component 66 is fixedly connected to the external of the cylinder 61. The limit component 66 is used to limit the range of motion of the rotating clamp 65 to ensure the accuracy and stability of its movement and prevent damage to the sample or mechanism due to excessive rotation.

[0034] The limiting component 66 includes a fixing plate 661, which provides a mounting point for the rotating shaft 662 to ensure the stability of the center position of the rotating clamp 65 when it rotates. The fixing plate 661 is externally fixedly connected to the outside of the cylinder 61. Two rotating shafts 662 are fixedly connected to the outside of the fixing plate 661. The rotating shafts 662 serve as the rotation fulcrum for the rotating clamp 65. The rotating clamp 65 is rotatably connected to the outside of the rotating shafts 662. The rotating clamp 65 is used to enable the rotating clamp 65 to rotate around the rotating shafts 662 to achieve the clamping operation of the cable sample. Two fans 3 are fixedly connected to the inside of the outer shell 1 on both sides. The fans 3 are used to quickly and evenly distribute the heat generated by the heating rods 4 inside the outer shell 1 when simulating a high-temperature aging environment, so as to avoid local overheating or underheating and ensure the uniformity of the test environment temperature. Two heating rods 4 are fixedly connected to the inside of the outer shell 1. The heating rods 4 use high-efficiency heating materials and can quickly raise the temperature inside the outer shell 1 to the set value to simulate the aging conditions of the cable in a high-temperature environment.

[0035] The water collection mechanism 5 includes a water leakage hole 51, which is used to prevent liquid from accumulating in the test area. The external part of the water leakage hole 51 is fixedly connected to the inside of the housing 1. A water collection tank 52 is fixedly connected to the bottom of the water leakage hole 51. The water collection tank 52 is used to store the liquid flowing down from the water leakage hole 51. It adopts a large capacity design to reduce the frequency of liquid pouring. At the same time, it has a leak-proof structure to ensure safe use. The top of the water leakage hole 51 is fixedly connected to the bottom of the cylinder 61.

[0036] Reference Figure 1 , Figure 2 and Figure 4The swing mechanism 7 includes a motor 71, with a transmission disk 73 fixedly connected to the drive end of the motor 71. The transmission disk 73 receives and transmits the rotational motion of the motor 71, providing power for the subsequent transmission structure. A transmission column 74 is fixedly connected to the bottom of the transmission disk 73, converting the rotational motion of the transmission disk 73 into a combined sliding and swinging motion along the second rotation shaft 76. The second rotation shaft 76 is slidably connected inside the transmission column 74. Driven by the transmission column 74, the second rotation shaft 76 slides along its own axis and swings around the limiting shaft 75, providing power for the movement of the connecting block 77. A connecting block 77 is fixedly connected to the outside of the second rotation shaft 76, transmitting the movement of the second rotation shaft 76 to the nozzle 78, driving the nozzle. The nozzle 78 swings, and the internal rotation of the connecting block 77 is connected to the limiting shaft 75. The limiting shaft 75 restricts the swing range of the connecting block 77, ensuring the stability and accuracy of the movement of the connecting block 77, so that the swing of the nozzle 78 meets the test requirements. The limiting shaft 75 is fixedly connected to the external limiting frame 72, which provides the mounting and fixing point for the limiting shaft 75 and forms a stable connection with the motor 71, ensuring the stability of the entire swing mechanism 7 during operation. The top outer side of the limiting frame 72 is fixedly connected to the outside of the motor 71. Multiple nozzles 78 are fixedly connected to the bottom of the connecting block 77. The nozzles 78 spray water mist evenly inside the outer shell 1 through the evenly distributed nozzles 78, quickly adjusting the ambient humidity and simulating a humid and hot aging environment.

[0037] Working principle: Open the transparent door 2 of the outer casing 1, place the insulated cable material to be tested in the initial position of the fixing mechanism 6, and drive the push plate 62 forward via cylinder 61. The push plate 62 drives the connecting rotating plates 63 on both sides to rotate, and the connecting rotating plates 63 in turn pull the connecting rotating plates 64, causing the rotating clamp 65 to rotate inward around the rotating shaft 662 on the fixing plate 661 until the cable material is clamped and fixed. Then close the transparent door 2. According to the test requirements, if it is necessary to simulate a high-temperature aging environment, start the heating rods 4 and fans 3 on both sides inside the outer casing 1. The heating rods 4 start to heat up, and the fans 3 evenly distribute the heat inside the outer casing 1. The internal temperature is quickly and evenly adjusted to the set value. To simulate a humid and hot aging environment, the transmission disk 73 is driven to rotate by the motor 71. The transmission column 74 at the bottom of the transmission disk 73 rotates accordingly. The transmission column 74 slides with the rotating shaft 76. Under the restriction of the limiting shaft 75 and the limiting connecting bracket 72, the connecting block 77 is driven to swing. The nozzle 78 at the bottom of the connecting block 77 swings and sprays water mist to increase the humidity inside the outer shell 1. At the same time, in conjunction with the heating rod 4 and the fan 3, a humid and hot aging environment is created. The liquid can flow into the water collection tank 52 below through the water leakage hole 51 of the water collection mechanism 5 for collection, so as to avoid the liquid affecting the test environment and normal operation of the equipment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
