Description

Technical Field

[0001] This invention relates to the field of seal testing, and in particular to a seal testing device for insulating gloves. Background Technology

[0002] In live-line work in the power industry, the sealing performance of insulating gloves is crucial to ensure the safety of workers. However, existing methods for testing the sealing performance of insulating gloves have several shortcomings. On the one hand, after the gloves are installed, they still need to be secured with cable ties. This process is not only cumbersome but can also lead to damage to the gloves or poor sealing due to improper use of the cable ties, further affecting the accuracy and reliability of the test. On the other hand, traditional testing methods are inefficient, cannot accurately locate leaks, and have poor sealing performance, making it difficult to meet the high requirements of modern power operations for the testing of insulating gloves. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is that: the existing sealing test of insulating gloves requires the use of ties to fix the insulating gloves after installation, which makes the operation cumbersome and easily damages the gloves; and the current test method is inefficient and cannot accurately locate the leak.

[0004] The above-mentioned technical problems are solved by the following technical solution: This invention proposes an insulating glove sealing detection device, which includes, The mold includes a frame, an inner sealing strip disposed on the outside of the frame, and an outer sealing strip; A limiting ring is fixedly connected to the outside of the mold, and the limiting ring is located between the inner sealing strip and the outer sealing strip; Specifically, an insulating glove is fitted onto the mold, with its opening located inside the limiting ring and covering the inner sealing strip. The inner and outer sealing strips are then inflated. The inflated inner sealing strip compresses the insulating glove from the inside, filling the gap between it and the mold frame, thus achieving an internal seal. The inflated outer sealing strip then compresses the limiting ring from the outside, uniformly pressing the outer wall of the insulating glove. This seals the outside of the glove and, in conjunction with the inner and outer clamping of the inner sealing strip, securely fixes the glove. This method ensures extremely high sealing performance during testing, guaranteeing the accuracy of pressure and thermal imaging results, while also enabling rapid and stable installation of the insulating glove without the need for secondary fixation using tools such as ties.

[0005] In a preferred embodiment of the insulating glove sealing detection device of the present invention: the limiting ring includes a mounting ring fixedly connected to the outside of the mold, and a paddle uniformly fixedly connected to the outside of the mounting ring; Specifically, the inflated outer sealing strip will simultaneously produce a sealing effect in two directions. First, it will evenly compress the circumferentially distributed paddles, causing the paddles to undergo inward elastic deformation, thereby collectively gripping the outer wall of the insulating glove and achieving initial sealing and fixation. Second, after inflation, the outer sealing strip itself will directly overflow through the gap between two adjacent sets of paddles and contact and compress the insulating glove, forming a secondary seal.

[0006] In a preferred embodiment of the insulating glove sealing detection device of the present invention: a guide ring is fixedly connected to the outside of the mold, and the outer sealing strip is located between the guide ring and the limiting ring; Specifically, when the outer sealing strip is inflated, the guide ring can guide its expansion force mainly towards the direction of the limiting ring. This guiding effect ensures that the expansion of the outer sealing strip is more controllable and uniform, so that its sealing pressure can be more concentrated and efficient on the limiting ring and the glove, ensuring the sealing and fixing effect.

[0007] In a preferred embodiment of the insulating glove sealing detection device of the present invention: both the paddle and the guide ring extend toward the inner sealing strip, and their extension paths gradually expand outward; Specifically, the flared structure of the lever, facing the opening of the insulating glove, serves as a guide during glove installation. It easily guides the opening of the insulating glove into the sealing area between the inner and outer sealing strips, effectively preventing installation difficulties or glove curling due to misalignment. It also ensures that the outer sealing strip effectively compresses the lever, deforming it to achieve sealing and fixation. The outward expansion of the guide ring ensures sufficient space for the outer sealing strip to expand and guides it.

[0008] In a preferred embodiment of the insulating glove sealing detection device of the present invention: the mold includes a sleeve, a mounting plate and an inner plate, the sleeve is fixedly connected to the inner plate, the sleeve is rotatably connected to the mounting plate, a servo motor is provided inside the mounting plate, and the output end of the servo motor is fixedly connected to the inner plate; Specifically, the servo motor can drive the inner plate and the sleeve to rotate, thereby causing the insulating glove fitted on the outside of the sleeve to rotate. The orientation of the insulating glove can be adjusted according to the specific situation, so that the detection component can scan the surface of the insulating glove from different angles, which improves the accuracy and detection efficiency of leak location to a certain extent.

[0009] In a preferred embodiment of the insulating glove sealing detection device of the present invention: a heating element is provided at the top of the inner plate, the heating element including a heating wire fixedly connected to the top of the inner plate, and a ceramic sleeve sleeved on the outside of the heating wire; Specifically, the heating wire is used to heat the air flowing through it to ensure that thermal imaging detection can be used effectively; the ceramic sleeve wraps around the heating wire, and by utilizing the excellent high temperature resistance and heat insulation properties of ceramic materials, it can not only concentrate heat on the heating airflow and improve thermal efficiency, but also effectively prevent high temperature from being directly transferred to the inner plate and other surrounding metal parts, thus avoiding equipment temperature rise or potential thermal damage caused by heat diffusion.

[0010] In a preferred embodiment of the insulating glove sealing detection device of the present invention: a pressure transmitter is installed inside the sleeve, and a temperature sensor and a pressure sensor are also installed inside the sleeve; Specifically, the pressure transmitter is used to accurately measure and convert the pressure signal inside the glove, the temperature sensor is used to monitor the temperature of the gas filled into the glove in real time to ensure that it is within the optimal and safe temperature range required for thermal imaging detection, and the pressure sensor is used to monitor the inflation pressure, forming the data acquisition end of the over-temperature and over-pressure protection module together with the temperature sensor; the three transmit real-time data to the controller, which makes a comprehensive judgment to achieve accurate sealing judgment and safety protection.

[0011] In a preferred embodiment of the insulating glove sealing detection device of the present invention, it further includes: The base, wherein the mounting plate is fixedly connected to the top of the base; The controller is located at the top of the base, and a detection element is provided at the top of the controller. The controller centrally processes data from various sensors and coordinates the operation of all actuators, such as the servo motor, the air pump, the heating wire, and the camera.

[0012] In a preferred embodiment of the insulating glove sealing detection device of the present invention: the base is provided with three sets of air pumps. The first set of air pumps inflates the glove through an air pipe, the second set of air pumps is connected to the inner sealing strip through an air pipe, and the third set of air pumps is connected to the outer sealing strip through an air pipe. The air pipe for inflating the glove passes through the inside of the heating wire. The pipe responsible for inflating the insulating glove passes through the inside of the heating wire. This design allows the airflow to be directly and efficiently heated, ensuring that the temperature of the gas inflated into the glove is uniform and quickly reaches the set value, ensuring that thermal imaging detection can be used effectively.

[0013] In a preferred embodiment of the insulating glove sealing detection device of the present invention: the detection component includes a bracket fixedly connected to the top of the controller, and a camera installed at one end of the bracket; Specifically, the bracket can adjust the height and angle of the camera. The camera is preferably a thermal imaging camera to ensure that it can capture the temperature distribution image on the surface of the insulating glove in a non-contact manner and transmit the image data to the controller in real time. By analyzing these image data, the controller can intuitively and quickly identify the local temperature abnormality area caused by high-pressure hot air leakage, thereby accurately locating the perforation position on the insulating glove and realizing visual detection and precise positioning.

[0014] The beneficial effects of this invention are as follows: by using the inner sealing strip and the outer sealing strip in conjunction with the limiting ring to achieve quick clamping and reliable sealing, and by combining heating and inflation, rotation detection and thermal imaging technology, efficient, accurate and automated sealing detection and leak location of insulating gloves are achieved, which significantly improves the safety and reliability of detection.

[0022] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new techniques. Furthermore, specific terms may be chosen independently, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of the invention.

[0024] Reference Figures 1-5 This embodiment provides an insulating glove sealing detection device, which includes, Mold 1 includes a frame 11, an inner sealing strip 12 disposed on the outside of the frame 11, and an outer sealing strip 13; Limiting ring 2 is fixedly connected to the outside of mold 1, and the limiting ring 2 is located between inner sealing strip 12 and outer sealing strip 13; Specifically, the insulating glove is placed on the mold 1, with the opening of the insulating glove located inside the limiting ring 2 and covered by the inner sealing strip 12. At this time, the inner sealing strip 12 and the outer sealing strip 13 are inflated. After inflation, the inner sealing strip 12 squeezes the insulating glove from the inside, filling the gap between it and the mounting frame 11, thus completing the internal seal. The inflated outer sealing strip 13 then squeezes the limiting ring 2 from the outside, thereby evenly pressing the outer wall of the insulating glove through the limiting ring 2. This not only seals the outside of the insulating glove but also, in conjunction with the inner and outer clamping of the inner sealing strip 12, achieves a stable fixation of the insulating glove. This method ensures extremely high sealing performance during testing, thereby ensuring the accuracy of pressure and thermal imaging test results, and also achieves rapid and stable installation of the insulating glove without the need for secondary fixation using tools such as ties.

[0025] The limiting ring 2 includes a mounting ring 21 fixedly connected to the outside of the mold 1, and a paddle 22 evenly fixedly connected to the outside of the mounting ring 21; Specifically, the inflated outer sealing strip 13 will simultaneously produce a sealing effect in two directions. First, it will evenly compress the circumferentially distributed paddles 22, causing the paddles 22 to undergo inward elastic deformation, thereby jointly wrapping the outer wall of the insulating glove and achieving initial sealing and fixation. Second, after inflation, the outer sealing strip 13 itself will directly overflow through the gap between two adjacent sets of paddles 22 and contact and compress the insulating glove, forming a secondary seal.

[0026] A guide ring 131 is fixedly connected to the outside of the mold 1, and the outer sealing strip 13 is located between the guide ring 131 and the limiting ring 2; Specifically, when the outer sealing strip 13 is inflated, the guide ring 131 can guide its expansion force mainly towards the direction of the limiting ring 2. This guiding effect ensures that the expansion of the outer sealing strip 13 is more controllable and uniform, so that its sealing pressure can be more concentrated and efficient on the limiting ring 2 and the glove, ensuring the sealing and fixing effect.

[0027] Both the paddle 22 and the guide ring 131 extend toward the inner sealing strip 12, and their extension paths gradually expand outward. Specifically, the flared structure of the lever 22, which faces the opening of the insulating glove, serves as a guide during installation. This allows the opening of the insulating glove to be easily guided into the sealing area between the inner sealing strip 12 and the outer sealing strip 13, effectively avoiding installation difficulties or glove curling caused by misalignment. It also ensures that the outer sealing strip 13 can effectively compress the lever 22, causing it to deform and complete the sealing and fixing. The outward expansion of the guide ring 131 ensures that the outer sealing strip 13 has sufficient space when it expands and guides it.

[0028] As one embodiment provided, such as Figures 1-3 The mold 1 includes a sleeve 111, a mounting plate 112 and an inner plate 113. The sleeve 111 is fixedly connected to the inner plate 113, and the sleeve 111 is rotatably connected to the mounting plate 112. A servo motor 114 is provided inside the mounting plate 112, and the output end of the servo motor 114 is fixedly connected to the inner plate 113. Specifically, the servo motor 114 can drive the inner plate 113 and the sleeve 111 to rotate, thereby causing the insulating glove fitted on the outside of the sleeve 111 to rotate. The orientation of the insulating glove can be adjusted according to the specific situation, so that the detection component 41 can scan the surface of the insulating glove from different angles, which improves the accuracy and detection efficiency of leak location to a certain extent.

[0029] As one embodiment provided, such as Figures 1-3 , Figure 6 The top of the inner plate 113 is provided with a heating element 14, which includes a heating wire 141 fixedly connected to the top of the inner plate 113, and a ceramic sleeve 142 sleeved on the outside of the heating wire 141. Specifically, the heating wire 141 is used to heat the air flowing through it to ensure that thermal imaging detection can be used effectively; the ceramic sleeve 142 is wrapped around the outside of the heating wire 141. Utilizing the excellent high temperature resistance and heat insulation properties of ceramic materials, it can not only concentrate heat on the heating airflow and improve thermal efficiency, but also effectively prevent high temperature from being directly transferred to the inner plate 113 and other surrounding metal parts, avoiding equipment temperature rise or potential thermal damage caused by heat diffusion.

[0030] A pressure transmitter 15 is installed inside the sleeve 111, and a temperature sensor and a pressure sensor are also installed inside the sleeve 111. Specifically, the pressure transmitter 15 is used to accurately measure and convert the pressure signal inside the glove, the temperature sensor is used to monitor the temperature of the gas filled into the glove in real time to ensure that it is within the optimal and safe temperature range required for thermal imaging detection, and the pressure sensor is used to monitor the inflation pressure, together with the temperature sensor, forming the data acquisition end of the over-temperature and over-pressure protection module; the three transmit the real-time data to the controller 4, which makes a comprehensive judgment to achieve accurate sealing judgment and safety protection.

[0031] It also includes a base 3, with a mounting plate 112 fixedly connected to the top of the base 3; The controller 4 is located at the top of the base 3, and a detection element 41 is provided at the top of the controller 4. The controller 4 centrally processes the data from each sensor and coordinates the operation of all execution units such as the servo motor 114, the air pump 31, the heating wire 141, and the camera 412.

[0032] The base 3 is equipped with three sets of air pumps 31. The first set of air pumps 31 inflates the glove through an air tube, the second set of air pumps 31 is connected to the inner sealing strip 12 through an air tube, and the third set of air pumps 31 is connected to the outer sealing strip 13 through an air tube. The air tube for inflating the glove passes through the inside of the heating wire 141. The pipe responsible for inflating the insulating glove passes through the inside of the heating wire 141. This design allows the airflow to be heated directly and efficiently, ensuring that the temperature of the gas inflated into the glove is uniform and quickly reaches the set value, ensuring that thermal imaging detection can be used effectively.

[0033] The detection component 41 includes a bracket 411 fixedly connected to the top of the controller 4, and a camera 412 installed at one end of the bracket 411; Specifically, the bracket 411 can adjust the height and angle of the camera 412. The camera 412 is preferably a thermal imaging camera to ensure that it can capture the temperature distribution image on the surface of the insulating glove in a non-contact manner and transmit the image data to the controller 4 in real time. By analyzing these image data, the controller 4 can intuitively and quickly identify the local temperature abnormality area caused by high-pressure hot air leakage, thereby accurately locating the perforation position on the insulating glove and realizing visual detection and precise positioning.

[0034] In summary, when testing insulating gloves, the insulating gloves are placed on the mounting frame 11, with their open end covering the inner sealing strip 12 and positioned inside the limiting ring 2. Subsequently, the second set of air pumps 31 inflates the inner sealing strip 12, causing it to squeeze the glove from the inside and fill the gap between it and the mounting frame 11, achieving an internal seal. Simultaneously, the third set of air pumps 31 inflates the outer sealing strip 13. Its expansion force is guided by the guide ring 131, uniformly squeezing the circumferentially distributed paddles 22, causing them to deform inwards and tightly grip the outer wall of the glove. Furthermore, the gas directly squeezes the glove through the gaps between the paddles 22, forming a double seal and stable clamping. This process requires no additional fixing such as clamps, and the flared outward structure of the paddles 22 and the guide ring 131 ensures... The device provides installation guidance and sealing space. After sealing, the first set of air pumps 31 heats the airflow through the air tube inside the heating wire 141 and then fills the glove. The heating wire 141 efficiently heats the airflow under the heat insulation protection of the ceramic sleeve 142. The pressure transmitter 15, temperature sensor, and pressure sensor monitor the internal pressure and temperature in real time, and transmit the data to the controller 4 to achieve precise control and over-temperature and over-pressure protection. If the filled hot air escapes from the glove leak point, it will cause local temperature changes. At this time, the servo motor 114 drives the inner plate 113 and the sleeve 111 to rotate, which drives the insulating glove to rotate. This allows the camera 412 mounted on the bracket 411 to scan from multiple angles, capture abnormal temperature images, and transmit them back to the controller 4 for analysis, thereby quickly and accurately locating the perforation. The device achieves quick clamping and reliable sealing through the inner sealing strip 12 and the outer sealing strip 13 in conjunction with the limiting ring 2. Combined with heating and filling, rotation detection, and thermal imaging technology, it realizes efficient, accurate, and automated sealing detection and leak point location of insulating gloves, significantly improving the safety and reliability of the detection.

[0035] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
