Description

Technical Field

[0001] This utility model relates to the field of cable inspection technology, and in particular to a non-contact cable temperature inspection device. Background Technology

[0002] In the field of power facility operation and maintenance, non-contact cable temperature monitoring devices play a crucial role. With the widespread application of cables in various scenarios, real-time and accurate monitoring of their operating temperature has become a key link in ensuring a safe and stable power supply. Non-contact temperature measurement methods, with their advantages of not requiring direct contact with cables and being easy to operate, are gradually becoming the mainstream temperature measurement method.

[0003] Traditional non-contact cable temperature inspection devices suffer from significant temperature measurement accuracy when the distance between the thermal imaging thermometer and the cable being tested is too great. This weakens the thermal radiation signal received by the thermal imaging thermometer, leading to deviations in the temperature measurement data and an inability to accurately reflect the true temperature condition of the cable.

[0004] Therefore, to address the shortcomings of traditional non-contact cable temperature inspection devices, a new non-contact cable temperature inspection device can be designed. This device uses an infrared ranging mechanism installed above the thermal imaging temperature measurement mechanism. This mechanism can provide real-time feedback on the distance between the thermal imaging temperature measurement mechanism and the cable being measured. Based on this distance information, operators can flexibly adjust the length of the extension rod to change the distance between the thermal imaging temperature measurement mechanism and the cable, thereby facilitating the solution of the aforementioned problems. Utility Model Content

[0005] To overcome the shortcomings of traditional non-contact cable temperature inspection devices, where the temperature measurement accuracy is significantly affected when the distance between the thermal imaging thermometer and the cable being tested is too far, easily leading to deviations in the temperature measurement data and failing to accurately reflect the true temperature condition of the cable, this utility model provides a non-contact cable temperature inspection device.

[0006] The technical solution is as follows: A non-contact cable temperature inspection device includes a main pole, an extension pole, a thermal imaging temperature measurement mechanism, an infrared ranging mechanism, a triangular handle, and a monitoring screen; the front end of the main pole is provided with an extension pole for extending according to the position of the temperature measuring cable, the front end of the extension pole is provided with a thermal imaging temperature measurement mechanism for thermal imaging testing of the cable temperature, above the thermal imaging temperature measurement mechanism is provided with an infrared ranging mechanism for feedback of the distance between the thermal imaging temperature measurement mechanism and the cable under test, the rear end of the extension pole is provided with a triangular handle for easy gripping by the user, and the upper end of the main pole is provided with a monitoring screen for feedback of inspection data.

[0007] Furthermore, the front end of the main rod is provided with a movable connecting seat, the center of which is provided with a movable connecting groove, and the center of the two side walls of the movable connecting groove is provided with a first fastening hole. The lower end of the thermal imaging temperature measurement mechanism is provided with a support platform, and the lower end of the support platform is provided with a movable connecting wheel extending to the movable connecting groove.

[0008] Furthermore, the center of the movable connecting wheel is provided with a second fastening hole corresponding to the first fastening hole, and the first fastening hole and the second fastening hole are provided with a locking mechanism.

[0009] Furthermore, the lower end of the infrared ranging mechanism is provided with a buckle, and the upper end of the thermal imaging temperature measuring mechanism is provided with a corresponding buckle seat. The infrared ranging mechanism and the thermal imaging temperature measuring mechanism are connected to the buckle and the seat, and the thermal imaging temperature measuring mechanism and the infrared ranging mechanism are electrically connected to the monitoring screen.

[0010] Furthermore, a motor slot is provided inside the main rod near the extension rod, and a micro motor is installed inside the motor slot. A lead screw connected to the micro motor is installed inside the extension rod, and an arc-shaped cover plate is provided at the outer end of the motor slot.

[0011] Furthermore, a vertical handle is provided below the monitoring screen to match the triangular handle. The lower end of the vertical handle is connected to the rear surface of the main rod, and a connection hole is provided at the center of the upper end of the vertical handle.

[0012] Furthermore, the lower end of the monitoring screen is symmetrically provided with two sets of movable sleeves, and a second movable shaft is provided between the two sets of movable sleeves. The lower center of the second movable shaft is provided with a connecting rod extending to the connecting hole.

[0013] The beneficial effects are that, compared to traditional non-contact cable temperature inspection devices, which have inherent drawbacks during use, this application, by incorporating an infrared ranging mechanism, can provide real-time feedback on the distance between the thermal imaging temperature measurement mechanism and the cable being measured. Operators can flexibly adjust the length of the extension rod based on this information, changing the distance between the thermal imaging temperature measurement mechanism and the cable to maintain it within a suitable range, thereby effectively improving temperature measurement accuracy and accurately reflecting the true temperature condition of the cable. The design of the movable connecting seat, movable connecting groove, and movable connecting wheel allows the thermal imaging temperature measurement mechanism to flexibly adjust its angle to adapt to cables in different positions and orientations, expanding the temperature measurement range and enhancing the overall performance of the device. In complex environments, the use of a micro motor and lead screw enables electric extension and retraction of the extension rod, allowing for more precise control of the extension length and improving operational efficiency. Simultaneously, the combination of a vertical handle and a triangular handle provides additional gripping points for workers, reducing effort during prolonged operation or device adjustments. The thermal imaging temperature measurement mechanism and infrared ranging mechanism are electrically connected to the monitoring screen, ensuring that distance information and temperature data are transmitted to the screen in real time, allowing workers to simultaneously access crucial information. The monitoring screen can be flexibly adjusted in angle via a movable sleeve, a second movable axis, and a connecting rod, allowing workers to rotate the screen according to their preferred viewing angle for a clearer view of the data.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1-5 As shown, a non-contact cable temperature inspection device includes a main pole 1, an extension pole 2, a thermal imaging temperature measurement mechanism 3, an infrared ranging mechanism 4, a triangular handle 5, and a monitoring screen 6. The front end of the main pole 1 is provided with an extension pole 2 for extending according to the position of the temperature measuring cable. The front end of the extension pole 2 is provided with a thermal imaging temperature measurement mechanism 3 for thermal imaging testing of the cable temperature. Above the thermal imaging temperature measurement mechanism 3 is an infrared ranging mechanism 4 for feeding back the distance between the thermal imaging temperature measurement mechanism 3 and the cable being tested. The rear end of the extension pole 2 is provided with a triangular handle 5 for easy gripping by the user. The upper end of the main pole 1 is provided with a monitoring screen 6 for feeding back inspection data.

[0023] The front end of the main rod 1 is provided with a movable connecting seat 12, and a movable connecting groove 13 is opened in the center of the movable connecting seat 12. The center of the two side walls of the movable connecting groove 13 is provided with a first fastening hole 14. The lower end of the thermal imaging temperature measuring mechanism 3 (the thermal imaging temperature measuring mechanism 3 model is HIKMICRO M10) is provided with a support platform 15. The lower end of the support platform 15 is provided with a movable connecting wheel 16 extending to the movable connecting groove 13. Through the movable connecting seat 12, the movable connecting groove 13, and the first fastening hole 14, the thermal imaging temperature measuring mechanism 3 can flexibly adjust the angle to adapt to cables in different positions and directions, expand the temperature measuring range, and improve the applicability of the device in complex environments.

[0024] The center of the movable connecting wheel 16 is provided with a second fastening hole 17 corresponding to the first fastening hole 14. The first fastening hole 14 and the second fastening hole 17 are provided with a locking mechanism 18. Through the first fastening hole 14 and the second fastening hole 17, and with the locking mechanism 18 inside both, the thermal imaging temperature measuring mechanism 3 can be quickly fixed after being adjusted to a suitable angle, so as to avoid the temperature measuring accuracy being affected by the angle deviation and to ensure the stability of the monitoring process.

[0025] The infrared ranging mechanism 4 (model VL53L0X) has a buckle 19 at its lower end, and the thermal imaging temperature measuring mechanism 3 has a corresponding bracket 20 at its upper end. The infrared ranging mechanism 4 and the thermal imaging temperature measuring mechanism 3 are connected to the bracket 20 via the buckle 19. The thermal imaging temperature measuring mechanism 3 and the infrared ranging mechanism 4 are electrically connected to the monitoring screen 6. The infrared ranging mechanism 4 and the thermal imaging temperature measuring mechanism 3 are connected via the buckle 19 and the bracket 20, and both are electrically connected to the monitoring screen 6 to ensure that distance information and temperature measurement data are transmitted to the monitoring screen 6 in real time, allowing staff to simultaneously grasp key information.

[0026] The main rod 1 has a motor slot 9 inside the end near the extension rod 2. The motor slot 9 contains a micro motor 10. The extension rod 2 contains a lead screw connected to the micro motor 10. The outer end of the motor slot 9 is fitted with an arc-shaped cover plate 11. Through the cooperation of the micro motor 10 and the lead screw, the extension rod 2 can be electrically extended and retracted, replacing manual adjustment, saving manpower, and allowing for more precise control of the extension length. The arc-shaped cover plate 11 provides a closed protection for the motor slot 9.

[0027] Below the monitoring screen 6 is a vertical handle 7 that works with the triangular handle 5. The lower end of the vertical handle 7 is connected to the rear surface of the main rod 1. A connection hole 8 is provided at the center of the upper end of the vertical handle 7. The vertical handle 7, in conjunction with the triangular handle 5, provides an additional gripping point for the staff, making it easier to operate or adjust the device for extended periods of time.

[0028] The lower end of the monitoring screen 6 is symmetrically provided with two sets of movable sleeves 21, and a second movable shaft 23 is provided between the two sets of movable sleeves 21. The lower end of the center of the second movable shaft 23 is provided with a connecting rod 22 extending to the connecting hole 8. Through the movable sleeves 21, the second movable shaft 23 and the connecting rod 22, the monitoring screen 6 can be flexibly adjusted in angle. Staff can rotate the monitoring screen 6 according to their own viewing habits to view the screen data more clearly.

[0029] When working, the staff first observes the position and direction of the cable, loosens the locking mechanism 18 on the movable connector 12, rotates the thermal imaging temperature measuring mechanism 3 to align it with the cable, and then re-locks it to fix the temperature measuring angle. Then, the staff adjusts the angle of the monitoring screen 6 through the movable sleeve 21 and the second movable shaft 23 to ensure that the screen data is clearly visible. Finally, the staff holds the triangular handle 5 and the vertical handle 7 with both hands to start the device.

[0030] After the device is started, the infrared ranging mechanism 4 immediately begins to work, measuring the distance to the cable under test in real time and displaying it on the monitoring screen 6. If the distance displayed on the monitoring screen 6 exceeds the optimal temperature measurement range of the thermal imaging temperature measuring mechanism 3, the staff will start the micro motor 10. The motor drives the lead screw to rotate, causing the extension rod 2 to automatically extend and retract until the distance is within the ideal range. During this process, the thermal imaging temperature measuring mechanism 3 simultaneously collects the thermal radiation signal of the cable, converts it into temperature data, and transmits it to the monitoring screen 6. The staff can observe the temperature value and distance information in real time and complete the inspection record.

[0031] Its working principle is as follows: the thermal imaging temperature measurement mechanism 3 uses infrared thermal imaging technology to receive the thermal radiation signal emitted by the cable and convert it into an electrical signal. After processing, the temperature information of the cable is obtained. The infrared ranging mechanism 4 emits infrared rays and receives the reflected infrared rays. Based on the propagation time of the infrared rays, it calculates the distance between the thermal imaging temperature measurement mechanism 3 and the cable being measured and converts the distance information into an electrical signal. A micro motor 10 is installed in the motor slot 9 inside the main rod 1 near the extension rod 2. The extension rod 2 has a lead screw connected to the micro motor 10. When the micro motor 10 is started, its output shaft drives the lead screw to rotate, thereby realizing the extension and retraction of the extension rod 2, and thus changing the distance between the thermal imaging temperature measurement mechanism 3 and the cable being measured.

[0032] Its beneficial effects are significant. By setting up an infrared ranging mechanism 4, this application can provide real-time feedback on the distance information between the thermal imaging temperature measuring mechanism 3 and the cable being measured. Based on this information, operators can flexibly adjust the length of the extension rod 2 to change the distance between the thermal imaging temperature measuring mechanism 3 and the cable, keeping the distance within a suitable range. This effectively improves the temperature measurement accuracy and accurately reflects the true temperature condition of the cable. The design of the movable connecting seat 12, movable connecting groove 13, and movable connecting wheel 16 allows the thermal imaging temperature measuring mechanism 3 to flexibly adjust its angle to adapt to cables in different positions and directions, expanding the temperature measurement range and improving the applicability of the device in complex environments. A micro motor 1 is also used. The extension rod 2 is electrically extended and retracted in conjunction with the lead screw, enabling more precise control of the extension length and improving operational efficiency. Simultaneously, the vertical handle 7 and the triangular handle 5 provide additional gripping points for operators, making long-term operation or device adjustments easier. The thermal imaging temperature measurement mechanism 3, the infrared ranging mechanism 4, and the monitoring screen 6 are electrically connected, ensuring that distance information and temperature data are transmitted to the monitoring screen 6 in real time, allowing operators to simultaneously grasp key information. The monitoring screen 6 can be flexibly adjusted in angle via the movable sleeve 21, the second movable shaft 23, and the connecting rod 22, allowing operators to rotate the monitoring screen 6 according to their own viewing habits for a clearer view of the screen data.
