Description

Technical Field

[0001] This invention relates to the technical field of power grid monitoring, and more specifically, to a device for monitoring overheating in distribution networks and its loading and unloading equipment. Background Technology

[0002] As the core component at the end of the power transmission system, the operating status of distribution network cables directly determines the reliability of terminal power supply and the overall operational safety of the power grid. Overheating during cable operation is a major cause of insulation aging and breakdown, short circuit tripping, and even fire accidents. Therefore, real-time and accurate temperature monitoring of cables is a core and critical task in the daily operation and maintenance of distribution networks.

[0003] Currently, temperature measurement of distribution network cables mainly relies on two solutions: manual inspection and fixed online monitoring. Manual inspection suffers from drawbacks such as low work efficiency, inability to achieve continuous real-time monitoring, and high safety risks associated with close-range live work, making it difficult to meet the needs of large-scale and routine operation and maintenance of distribution networks. Existing fixed online monitoring devices often have problems with installation and maintenance. Installation work requires power outages or manual high-altitude close-range live work, which requires highly skilled personnel, involves complex operating procedures, and poses significant safety risks. Furthermore, the device's clamping structure has poor fit with the cable, which can affect the accuracy of temperature measurement. Subsequent replacement and maintenance of temperature measurement components require power outages or close-range operations again. In addition, some devices require electric drive equipment, resulting in poor adaptability to field operations and insufficient operational reliability, making it difficult to adapt to the complex and ever-changing field operation and maintenance scenarios of distribution network cables. Summary of the Invention

[0004] The purpose of this invention is to provide a distribution network over-temperature monitoring device and its loading and unloading equipment, which can efficiently install the temperature measuring component onto the cable for temperature detection without requiring manual contact or proximity to the cable.

[0005] This invention is achieved through the following technical solution: The overheat monitoring device for power distribution networks and its loading / unloading equipment of this invention include a clamping assembly, a temperature measuring assembly detachably connected to the clamping assembly, and a lifting assembly detachably connected to the clamping assembly; the clamping assembly is used to clamp onto a cable; the clamping assembly includes an arc-shaped first clamping plate attached to the lower side of the cable, a rotating shaft rotatably disposed at one end of the first clamping plate, a torsion spring connecting the rotating shaft and the first clamping plate, a second clamping plate fixedly connected to the rotating shaft, and a pair of sleeves vertically disposed on both sides of the lower surface of the first clamping plate, one of which is opened in… The sleeve has a first through hole on its side wall, a pull rope connected to the second clamping plate, a spring inside the sleeve, and a limiting ball at the end of the pull rope; the lifting assembly includes a vertically arranged first insulating rod, a first connecting plate horizontally arranged at the upper end of the first insulating rod, a pair of top rods vertically arranged at both ends of the first connecting plate, and an annular groove formed on the side wall of the upper end of the top rod; one top rod is inserted into one sleeve, and the diameter of the limiting ball is smaller than the diameter of the first through hole; when the second clamping plate needs to be flipped, the limiting ball is inserted into the annular groove after passing through the first through hole.

[0006] Furthermore, the spring is fixedly connected to the lower side wall of the first clamping plate, and the upper end of the push rod is provided with a groove; when the push rod is inserted into the sleeve, the spring is located in the groove.

[0007] Furthermore, the first clamping plate has a clearance hole, in which a heat-conducting plate is provided. The heat-conducting plate is fixedly connected to the first clamping plate on both sides by a pair of first spring tabs. The side of the heat-conducting plate near the cable is an arc shape that fits with the cable, and the side of the heat-conducting plate away from the cable has a slot for accommodating the temperature measuring component.

[0008] Furthermore, the temperature measuring component includes a temperature measuring instrument and a base plate fixedly mounted on the temperature measuring instrument; the base plate is engaged in the slot, and the thickness of the base plate is greater than the depth of the slot.

[0009] Furthermore, it also includes a pair of limiting components for limiting the base plate, with the pair of limiting components respectively disposed on both sides of the temperature measuring instrument.

[0010] Furthermore, the limiting assembly includes a limiting plate horizontally disposed on the lower side of the base plate, a sliding rod connected to the limiting plate, and an arc-shaped second spring piece for connecting the limiting plate and the outer wall of the sleeve; the side wall of the sleeve has a horizontally disposed second through hole, and a horizontally disposed sliding tube is fixedly disposed at the second through hole; the sliding rod is slidably disposed in the second through hole and the sliding tube; the lifting assembly also includes a sleeve sleeved on the outer wall of the top rod, and a second connecting plate for connecting a pair of sleeves; the inner diameter of the sleeve is larger than the outer diameter of the sleeve.

[0011] Furthermore, the limiting plate has an elastic pad on the side near the base plate, and the pad abuts against the base plate; the lifting assembly also includes a second insulating rod that is vertically arranged and fixedly connected to the second connecting plate; the second insulating rod passes through the first insulating rod and is slidably connected to the first insulating rod.

[0012] Furthermore, the second through hole and the first through hole are located on the same circumference of the sleeve; when the end of the slide rod is located inside the sleeve and the annular groove and the first through hole are at the same height, the end of the slide rod can be locked in the annular groove.

[0013] Furthermore, the lifting assembly also includes a third insulating rod that passes through the second insulating rod, and a housing located at the upper end of the third insulating rod; the upper end of the housing is an open end, and the inner diameter of the housing is larger than the outer diameter of the thermometer.

[0014] Furthermore, the clamping assembly also includes a support plate fixedly disposed on the first clamping plate, and a guide hole opened on the support plate; the pull rope passes through the guide hole after passing around the end of the first clamping plate.

[0015] The technical solution of the present invention has at least the following advantages and beneficial effects: In the distribution network overheat monitoring device and its loading and unloading equipment, the temperature measuring component is first installed on the clamping component. Then, the push rod is inserted into the sleeve and the spring is compressed so that the annular groove at the end of the push rod coincides with the first through hole. Next, the pull rope is pulled, opening the second clamping plate. The limiting ball at the end of the pull rope passes through the first through hole and is then engaged in the annular groove. The push rod is then released, and under the action of the spring, it moves a certain distance outward from the sleeve. At this point, the first through hole and the annular groove are misaligned, and the limiting ball is engaged in the annular groove. Thus, the limiting ball, the annular groove, and the pull rope pull the second clamping plate. The gap between the ends of the second and first clamping plates is made large enough for the cable to pass through. The clamping assembly is then moved to the cable via the first insulating rod. When the first clamping plate contacts the underside of the cable, the first insulating rod and the push rod are pushed upwards. At this point, the spring is compressed, and the push rod extends into the sleeve. When the annular groove at the end of the push rod coincides with the first through hole, the limiting ball disengages from the annular groove and passes through the first through hole. At this point, the pull rope no longer exerts tension on the second clamping plate. The second clamping plate, under the action of the torsion spring on the rotating shaft, flips and adheres to the upper side of the cable. The cable is thus clamped and fixed using the first and second clamping plates, and the temperature sensing component can monitor the cable temperature. Throughout the entire process, no electrical equipment is required except for the temperature sensing component, and workers can operate safely while the cable is in operation, allowing for safe operation with the power on. Furthermore, the installation process is highly efficient, requiring no complex or high-precision operations. Attached Figure Description

Detailed Implementation

[0018] Example The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 13As shown, the distribution network overheat monitoring device and its loading and unloading equipment of this embodiment include a clamping assembly 10, a temperature measuring assembly 20 detachably connected to the clamping assembly 10, and a lifting assembly 30 detachably connected to the clamping assembly 10; the clamping assembly 10 is used to clamp the cable 50; the clamping assembly 10 includes an arc-shaped first clamping plate 11 attached to the lower side of the cable 50, a rotating shaft 12 rotatably disposed at one end of the first clamping plate 11, a torsion spring for connecting the rotating shaft 12 and the first clamping plate 11, a second clamping plate 13 fixedly connected to the rotating shaft 12, a pair of sleeves 14 vertically disposed on both sides of the lower surface of the first clamping plate 11, and a first... The lifting assembly 30 includes a through hole 141, a pull rope 15 connected to the second clamping plate 13, a spring 16 disposed in the sleeve 14, and a limiting ball 17 disposed at the end of the pull rope 15; the lifting assembly 30 includes a vertically arranged first insulating rod 31, a first connecting plate 32 horizontally disposed at the upper end of the first insulating rod 31, a pair of top rods 33 vertically disposed at both ends of the first connecting plate 32, and an annular groove 34 opened on the side wall of the upper end of the top rod 33; one top rod 33 is inserted into a sleeve 14, and the diameter of the limiting ball 17 is smaller than the diameter of the first through hole 141; when it is necessary to flip the second clamping plate 13, the limiting ball 17 is inserted into the annular groove 34 after passing through the first through hole 141. Specifically, in use, first install the temperature measuring component 20 onto the clamping component 10, then insert the push rod 33 into the sleeve 14 and compress the spring 16 so that the annular groove 34 at the end of the push rod 33 coincides with the first through hole 141. Then pull the pull rope 15 to open the second clamping plate 13, and let the limiting ball 17 at the end of the pull rope 15 pass through the first through hole 141 and be inserted into the annular groove 34. Then release the push rod 33, and the push rod 33 moves a certain distance outward from the sleeve 14 under the action of the spring 16. At this time, the first through hole 141 and the annular groove 34 are misaligned, and the limiting ball 17 is stuck in the annular groove 34 (as shown in the attached figure). Figure 6 - Appendix Figure 7As shown), at this point, the limiting ball 17, the annular groove 34, and the pull rope 15 pull the second clamping plate 13, making the gap between the end of the second clamping plate 13 and the end of the first clamping plate 11 sufficient for the cable 50 to pass through. Then, the clamping assembly 10 is sent to the cable 50 by the first insulating rod 31. When the first clamping plate 11 contacts the lower side of the cable 50, the first insulating rod 31 and the push rod 33 are pushed upward with force. At this time, the spring 16 is compressed, and the push rod 33 extends into the sleeve 14. When the annular groove 34 at the end of the top rod 33 coincides with the first through hole 141, the limiting ball 17 disengages from the annular groove 34 and passes through the first through hole 141. At this time, the pull rope 15 no longer exerts tension on the second clamping plate 13. Under the action of the torsion spring on the rotating shaft 12, the second clamping plate 13 flips and adheres to the upper side of the cable 50. At this time, the cable 50 is clamped and fixed by the first clamping plate 11 and the second clamping plate 13, and the temperature measuring component 20 can monitor the temperature of the cable 50. Throughout the entire process, no electrical equipment is required except for the temperature measuring component 20, and workers can stay as far away from the cable 50 as possible during operation, thus ensuring safe operation while the power is on. Furthermore, the installation process is highly efficient and does not require complex and high-precision operations.

[0019] In this embodiment, the spring 16 is fixedly connected to the lower side wall of the first clamping plate 11, and the upper end of the push rod 33 is provided with a groove 35. When the push rod 33 is inserted into the sleeve 14, the spring 16 is located in the groove 35. Specifically, when the push rod 33 is inserted into the sleeve 14, the spring 16 can be inserted into the groove 35 at the end of the push rod 33. This can effectively shorten the length of the sleeve 14, so that the end of the push rod 33 can contact the outer wall of the first clamping plate 11. In this way, it is not necessary to perform detailed positioning of the annular groove 34 and the first through hole 141. As long as the push rod 33 pushes to the top of the sleeve 14 (i.e., the first clamping plate 11, at which point the push rod 33 can no longer move upward), the first through hole 141 will automatically connect with the annular groove 34.

[0020] In this embodiment, the first clamping plate 11 has a clearance hole 111, in which a heat-conducting plate 18 is disposed. The heat-conducting plate 18 is fixedly connected to the first clamping plate 11 on both sides by a pair of first spring tabs 19. The side of the heat-conducting plate 18 closest to the cable 50 is arc-shaped to fit against the cable 50, while the side of the heat-conducting plate 18 furthest from the cable 50 has a slot 110 for accommodating the temperature-sensing component 20. Specifically, the heat-conducting plate 18 has high thermal conductivity (e.g., aluminum, copper), allowing it to efficiently conduct heat from the cable 50 to the temperature-sensing component 20. This eliminates the need for the temperature-sensing component 20 to directly contact the cable 50, effectively protecting it and preventing wear. Furthermore, the first spring tabs 19 always exert an upward elastic force on the heat-conducting plate 18, ensuring that the heat-conducting plate 18 remains firmly attached to the cable 50.

[0021] The temperature measuring component 20 in this embodiment includes a thermometer 21 and a base plate 22 fixedly mounted on the thermometer 21. The base plate 22 is fitted into a slot 110, and the thickness of the base plate 22 is greater than the depth of the slot 110. It also includes a pair of limiting components 40 for restricting the base plate 22, with the pair of limiting components 40 respectively located on both sides of the thermometer 21. Specifically, the thermometer 21 can measure the temperature of the cable 50 in real time and transmit the temperature data periodically (or continuously). The thermometer 21 can be powered by solar energy and can be equipped with a battery inside. Alternatively, a thermometer 21 with solar power capability can be used, which requires a thermometer 21 with a flat or regularly curved surface (as shown in the attached diagram). Figure 2 (As shown), this facilitates the installation of solar modules. This embodiment does not specifically design the thermometer 21 itself; therefore, any conventional or common model of thermometer 21 can be used. When installing the thermometer 21 onto the clamping assembly 10, the base plate 22 is inserted into the slot 110, and then the limiting assembly 40 is used to support and fix the base plate 22, ensuring that the base plate 22 is tightly attached to the heat-conducting plate 18.

[0022] The limiting component 40 in this embodiment includes a limiting plate 41 horizontally disposed on the lower side of the base plate 22, a sliding rod 42 connected to the limiting plate 41, and an arc-shaped second spring piece 44 for connecting the limiting plate 41 and the outer wall of the sleeve 14; the side wall of the sleeve 14 is provided with a horizontally disposed second through hole 46, and a horizontally disposed sliding tube 43 is fixedly disposed at the second through hole 46; the sliding rod 42 is slidably disposed in the second through hole 46 and the sliding tube 43; the lifting component 30 also includes a sleeve 36 sleeved on the outer wall of the top rod 33, and a second connecting plate 37 for connecting a pair of sleeves 36; the inner diameter of the sleeve 36 is larger than the outer diameter of the sleeve 14. Specifically, without any external force, the limiting plate 41 and the sliding rod 42 will always be under the bottom plate 22 under the elastic force of the second spring 44, supporting the bottom plate 22. When it is necessary to remove the thermometer 21 from the clamping assembly 10 (for replacement, maintenance, data calibration, etc.), simply insert the top rod 33 into the sleeve 14, and then push the sleeve 36 upward so that the sleeve 36 fits on the outside of the sleeve 14 and continues to move upward. During the upward movement, the sleeve 36 will contact the second spring 44 and press the second spring 44 against the outer wall of the sleeve 14. At this time, the second spring 44 will drive the limiting plate 41 and the sliding rod 42 to move into the sleeve 14. Then the limiting plate 41 can no longer support the bottom plate 22, and the thermometer 21 and the bottom plate 22 will naturally fall off the heat-conducting plate 18.

[0023] In this embodiment, the limiting plate 41 is provided with an elastic gasket 45 on the side near the base plate 22, and the gasket 45 abuts against the base plate 22; the lifting assembly 30 also includes a vertically arranged second insulating rod 38 fixedly connected to the second connecting plate 37; the second insulating rod 38 passes through the first insulating rod 31 and is slidably connected to the first insulating rod 31. Specifically, the gasket 45 can fill the gap between the limiting plate 41 and the base plate 22, and can effectively support the base plate 22. By pushing the second insulating rod 38, a pair of sleeves 36 can be moved through the second connecting plate 37. Similarly, the worker can operate the second insulating rod 38 away from the cable 50.

[0024] In this embodiment, the second through hole 46 and the first through hole 141 are located on the same circumference of the sleeve 14; when the end of the slide rod 42 is located inside the sleeve 14 and the annular groove 34 and the first through hole 141 are at the same height, the end of the slide rod 42 can be engaged in the annular groove 34. Specifically, by pushing the sleeve 36 upward, the slide rod 42 can pass through the second through hole 46 and be engaged in the annular groove 34 (as shown in the attached figure). Figure 8 - Appendix Figure 9 As shown in the state change diagram, this is equivalent to the top rod 33 and the sleeve 14 being connected as one unit via the slide rod 42, which means that the first insulating rod 31, the first connecting plate 32, the top rod 33, the sleeve 14, and the first clamping plate 11 are a single integrated structure. At this time, keeping the relative positions of the second insulating rod 38 and the first insulating rod 31 unchanged, pulling down the first insulating rod 31 and the second insulating rod 38 will directly remove the first clamping plate 11 and the second clamping plate 13 from the cable 50 (the second clamping plate 13 is held onto the cable 50 by the elastic force of a torsion spring, and can be directly pulled apart under a certain downward pulling force). After removing the clamping assembly 10, it can be reused.

[0025] The lifting assembly 30 in this embodiment also includes a third insulating rod 39 that passes through the second insulating rod 38, and a box 310 located at the upper end of the third insulating rod 39; the upper end of the box 310 is an open end, and the inner diameter of the box 310 is larger than the outer diameter of the thermometer 21. Specifically, the housing 310 is mainly used to install the thermometer 21. Before replacement, the thermometer 21 is placed in the housing 310 with the bottom plate 22 facing upwards. The above operation is required to remove the old thermometer 21. Then, while maintaining the compression of the second spring 44 by the sleeve 36, the third insulating rod 39 is moved upwards. The bottom plate 22 on the thermometer 21 is inserted into the slot 110 on the heat-conducting plate 18 through the housing 310. Then, the sleeve 36 is moved downwards so that the sleeve 36 no longer exerts force on the second spring 44. At this time, the second spring 44 returns to its original shape. The limiting plate 41 is pushed back to the underside of the bottom plate 22 to support the bottom plate 22. This completes the disassembly and installation of the thermometer 21. The clamping assembly 10 does not need to be removed during the entire process.

[0026] The clamping assembly 10 in this embodiment further includes a support plate 112 fixedly disposed on the first clamping plate 11, and a guide hole formed on the support plate 112; the pull rope 15 passes through the guide hole after passing around the end of the first clamping plate 11. Specifically, the support plate 112 and the guide hole can restrict the position of the pull rope 15.

[0027] In summary, the distribution network overheat monitoring device and its loading and unloading equipment of this embodiment are used by first installing the temperature measuring component 20 onto the clamping component 10, then inserting the push rod 33 into the sleeve 14 and forcefully compressing the spring 16 so that the annular groove 34 at the end of the push rod 33 coincides with the first through hole 141, then pulling the pull rope 15 to pull open the second clamping plate 13, and then passing the limiting ball 17 at the end of the pull rope 15 through the first through hole 141 and locking it into the annular groove 34. Then releasing the push rod 33, the push rod 33 moves a certain distance outward from the sleeve 14 under the action of the spring 16. At this time, the first through hole 141 and the annular groove 34 are misaligned, and the limiting ball 17 is locked in the annular groove 34. At this time, the limiting ball 17, the annular groove 34 and the pull rope 15 pull the second clamping plate 13, so that the end of the second clamping plate 13 coincides with the first through hole 141 and the second clamping plate 141. The gap between the ends of the first clamping plate 11 is sufficient for the cable 50 to pass through. Then, the clamping assembly 10 is sent to the cable 50 through the first insulating rod 31. When the first clamping plate 11 contacts the lower side of the cable 50, the first insulating rod 31 and the push rod 33 are pushed upward with force. At this time, the spring 16 is compressed and the push rod 33 extends into the sleeve 14. When the annular groove 34 at the end of the push rod 33 coincides with the first through hole 141, the limiting ball 17 is dislodged from the annular groove 34 and passes through the first through hole 141. At this time, the pull rope 15 no longer has a pulling force on the second clamping plate 13. The second clamping plate 13 is flipped and attached to the upper side of the cable 50 under the action of the torsion spring on the rotating shaft 12. At this time, the clamping and fixing of the cable 50 is achieved by the first clamping plate 11 and the second clamping plate 13. At this time, the temperature measuring assembly 20 can monitor the temperature of the cable 50. The entire process requires no electrical equipment other than the temperature sensing component 20, and workers can operate with the power on while keeping a safe distance from the cable 50. Furthermore, the installation process is highly efficient, requiring no complex or high-precision operations.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
