[0016] Preferably, a temperature sensor is fixedly connected to the surface of the oil storage ring, and the temperature sensor is powered by an external power supply.

[0017] A method for using a cable joint temperature monitoring device comprises the following steps:

[0018] S1: When protecting the cable joint, the two connected cables are clamped in the inner cavity of the lower protection box. The cable joint is located in the middle of the inner cavity of the lower protection box. Before connecting the two cables, one of the cables is passed through the inner ring of the oil storage ring and then connected to the other cable. When the cable passes through the inner cavity of the oil storage ring, the curved plate is elastically adjusted to extend the distance through the spring telescopic rod so that the curved plate can fit on the surface of the cable. When the curved plate fits well, the temperature sensing drive unit also fits on the surface of the cable. After completing the connection of the two cables, adjust the curved plate, the temperature sensing drive unit and the cable joint. The upper and lower protective boxes are then fixed with bolts. The assembled upper and lower protective boxes are collectively referred to as box bodies. The assembled box bodies are then fixed together. Air holes are provided on the surface of the lower protective box to facilitate heat dissipation in the box body. The inner cavity of the oil storage ring is filled with heat transfer oil. When high temperature is generated at the cable joint, the high temperature will be transferred to the spring telescopic rod through the curved plate, and then to the oil storage ring, and then to the heat transfer oil in the inner cavity of the oil storage ring. The spring telescopic rod and the oil storage ring are both made of copper, which can increase heat transfer. The high temperature at the cable joint can be effectively reduced by cooling the heat transfer oil.

[0019] S2: When high temperature is generated at the cable joint, the high temperature heats the gas storage pipe, and the helium in the gas storage pipe expands due to the heat, pushing the first piston. The movement of the first piston drives the magnetic block to move, and the magnetic block and the magnetic ring are in a magnetic attraction state. The movement of the magnetic block drives the magnetic ring to move in the same direction, and the movement of the magnetic ring drives the gear plate to move. The movement of the gear plate drives the gear meshing with it to rotate, and the rotation of the gear drives the rotating column to rotate. The rotation of the rotating column drives the rotating disk to rotate. The rotation of the rotating disk drives the two extrusion wheels to rotate. While the extrusion wheel rotates, it cooperates with the extrusion shell to squeeze the first hose, so that the inner cavity of the first hose forms a negative pressure area, and the heat transfer oil in the oil storage ring is absorbed. Then, the heat transfer oil in the first hose is transferred to the copper conduit through continuous extrusion of the extrusion wheel. The heat transfer oil entering the copper conduit is cooled by the air cooling unit, and then enters the second hose, and re-enters the inner cavity of the oil storage ring through the second hose;

[0020] S3: The heat-conducting oil enters the copper tube after being heated, and the heat it carries is transferred to the surface of the heat dissipation pipe through the copper tube. When the gear rotates, one end of the lever plate is pressed down, and the other end of the lever plate rises. At this time, the second spring is stretched. When the other end of the lever plate rises, the bottom of the vertical rod is lifted, so that the vertical rod moves vertically upward. The contact area between the lever plate and the vertical rod is sufficient to ensure that the lever plate will not lose contact with the bottom of the vertical rod when it rises. The upward movement of the vertical rod drives the limit plate to move upward, and the upward movement of the limit plate drives the second piston to move upward in the inner cavity of the second through-tube. The sliding connection between the vertical rod and the upper protective box also guides the movement trajectory of the second piston, increasing the stability of the second piston when it moves upward. The upward movement of the second piston extracts air from the inner cavity of the second through-tube, and a channel is formed between the second through-tube, the heat dissipation pipe and the first through-tube. When the second piston moves upward, the first through-tube end When the second piston moves up to the maximum distance, the through hole is exposed to the air, and the hot air extracted by the second piston is released. When the second piston moves up, the third spring is stretched. When the second piston loses the upward driving force, the reaction force of the third spring drives the second piston to reset to the inner cavity of the second through pipe. In the process of moving downward, the air in the second through pipe is squeezed, so that the hot air overflows through the port of the first through pipe, thereby realizing the continuous replacement of the hot air in the heat pipe and improving the cooling of the heated heat-conducting oil in the copper conduit. When the lever plate is pressed down to an appropriate distance, the lever plate is out of contact with the gear, that is, one end of the lever plate loses the downward pressure. At this time, the reaction force of the second spring realizes the reset of the rotation angle of the lever plate, so that one end of the lever plate is meshed with the gear again.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention, by providing an oil cooling unit, can utilize heat transfer oil to transfer the heat generated at the cable joint, thereby reducing the high temperature monitored at the cable joint, effectively reducing the adverse effects of high temperature on cable safety, slowing down the aging speed of the cable, and extending the service life of the cable.

[0023] 2. The present invention provides a temperature-sensing drive unit, which can generate drive through the thermal expansion of helium when the cable joint generates high temperature, thereby accelerating the flow rate of the heat transfer oil, thereby accelerating heat exchange, improving the cooling efficiency, and effectively reducing the adverse effects of high temperature on cable safety, slowing down the aging rate of the cable, and extending the service life of the cable.

[0024] 3. The present invention, by providing an air cooling unit, can cool the heat transfer oil extracted into the copper conduit by the temperature sensing drive unit, thereby realizing segmented cooling of the heated heat transfer oil, effectively improving the efficiency of cooling the monitored high temperature, reducing the adverse effects of high temperature on cable safety, slowing down the aging speed of the cable, and extending the service life of the cable.

[0050] The specific implementation of this embodiment is as follows: the heat-conducting oil enters the copper conduit 2213 after being heated, and the heat it carries is transferred to the surface of the heat dissipation pipe 2301 through the copper conduit 2213. When the gear 2208 rotates, one end of the lever plate 2309 is pressed down, and the other end of the lever plate 2309 rises. At this time, the second spring 2310 is stretched. When the other end of the lever plate 2309 rises, the bottom of the vertical rod 2307 is lifted, so that the vertical rod 2307 moves vertically upward. The contact area between the lever plate 2309 and the vertical rod 2307 is sufficient to ensure that the lever plate 2309 is lifted when it rises. The upward movement of the vertical rod 2307 drives the limit plate 2306 to move upward, and the upward movement of the limit plate 2306 drives the second piston 2304 to move upward in the inner cavity of the second through pipe 2303. The sliding connection between the vertical rod 2307 and the upper protective box 12 also guides the movement trajectory of the second piston 2304, thereby increasing the stability of the second piston 2304 when moving upward. The upward movement of the second piston 2304 extracts air from the inner cavity of the second through pipe 2303, and a channel is formed between the second through pipe 2303, the heat dissipation pipe 2301 and the first through pipe 2302. When the second piston 23 When the second piston 2304 moves upward, the air at the port of the first through pipe 2302 is extracted, so that the extracted air enters the inner cavity of the heat dissipation pipe 2301 to replace the hot air. A through hole 2305 is opened at the bottom of the second piston 2304. When the second piston 2304 moves upward to the maximum distance, the through hole 2305 is exposed to the air to release the hot air extracted by the second piston 2304. When the second piston 2304 moves upward, the third spring 2314 is stretched. When the second piston 2304 loses the upward driving force, the reaction force of the third spring 2314 drives the second piston 2304 to return to the second through pipe 2304. During the downward movement, the inner cavity of the tube 2303 squeezes the air in the second through-tube 2303, causing the hot air to overflow through the port of the first through-tube 2302, thereby realizing the continuous replacement of the hot air in the heat dissipation tube 2301 and improving the cooling of the heated heat-conducting oil in the copper conduit 2213. When the lever plate 2309 is pressed down to an appropriate distance, the lever plate 2309 is disengaged from the gear 2208, that is, one end of the lever plate 2309 loses the downward pressure. At this time, the reaction force of the second spring 2310 realizes the reset of the rotation angle of the lever plate 2309, so that one end of the lever plate 2309 is re-engaged with the gear 2208.

[0051] A method for using a cable joint temperature monitoring device comprises the following steps:

[0052] S1: When protecting the cable joint, the two connected cables are clamped in the inner cavity of the lower protection box 11. The cable joint is located in the middle position of the inner cavity of the lower protection box 11. Before connecting the two cables, one of the cables is passed through the inner ring of the oil storage ring 2101 and then connected to the other cable. When the cable passes through the inner cavity of the oil storage ring 2101, the curved plate 2104 is elastically adjusted to extend the distance through the spring telescopic rod 2103, so that the curved plate 2104 can fit on the surface of the cable. When the curved plate 2104 fits well, the temperature sensing drive unit 22 also fits on the surface of the cable. After completing the connection of the two cables, adjust the curved plate 2104 and the surface of the temperature sensing drive unit 22 and the cable joint. The upper and lower protective boxes 12 and 11 are fitted on the surface, and then the upper protective box 12 and the lower protective box 11 are fixed by bolts. Here, the assembled upper protective box 12 and the lower protective box 11 are collectively referred to as a box body, and then the assembled box body is fixed in one place. The surface of the lower protective box 11 is provided with air holes to facilitate the heat dissipation of the inner cavity of the box body. The inner cavity of the oil storage ring 2101 is filled with heat transfer oil. When high temperature is generated at the cable joint, the high temperature will be transmitted to the spring telescopic rod 2103 through the curved plate 2104, and then transmitted to the oil storage ring 2101, and then transmitted to the heat transfer oil in the inner cavity of the oil storage ring 2101. The spring telescopic rod 2103 and the oil storage ring 2101 are both made of copper, which can increase the heat transferability. The high temperature at the cable joint can be effectively reduced by cooling the heat transfer oil.

[0053] S2: When high temperature is generated at the cable joint, the high temperature heats the gas storage tube 2201, and the helium in the gas storage tube 2201 expands due to the heat, pushing the first piston 2202. The movement of the first piston 2202 drives the magnetic block 2203 to move. The magnetic block 2203 and the magnetic ring 2204 are in a magnetic attraction state. The movement of the magnetic block 2203 drives the magnetic ring 2204 to move in the same direction. The movement of the magnetic ring 2204 drives the tooth plate 2205 to move. The movement of the tooth plate 2205 drives the gear 2208 meshing therewith to rotate. The rotation of the gear 2208 drives the rotating column 2207 to rotate. The rotation of the rotating column 2207 drives The rotating disk 2210 is rotated, and the rotation of the rotating disk 2210 drives the two extrusion wheels 2211 to rotate. The extrusion wheels 2211 cooperate with the extrusion shell 2209 to squeeze the first hose 2212 while rotating, so that the inner cavity of the first hose 2212 forms a negative pressure area, and the heat transfer oil in the oil storage ring 2101 is absorbed. Then, the heat transfer oil in the first hose 2212 is transferred to the copper conduit 2213 through continuous squeezing of the extrusion wheel 2211. The heat transfer oil in the copper conduit 2213 is cooled by the air cooling unit 23, and then enters the second hose 2214, and re-enters the inner cavity of the oil storage ring 2101 through the second hose 2214;

[0054] S3: After being heated, the heat-conducting oil enters the copper conduit 2213, and the heat it carries is transferred to the surface of the heat dissipation pipe 2301 through the copper conduit 2213. When the gear 2208 rotates, one end of the lever plate 2309 is pressed down, and the other end of the lever plate 2309 rises. At this time, the second spring 2310 is stretched. When the other end of the lever plate 2309 rises, the bottom of the vertical rod 2307 is lifted, so that the vertical rod 2307 moves vertically upward. The contact area between the lever plate 2309 and the vertical rod 2307 is sufficient to ensure that the lever plate 2309 will not collide with the vertical rod 2307 when it rises. 7 is disconnected, the upward movement of the vertical rod 2307 drives the limit plate 2306 to move upward, and the upward movement of the limit plate 2306 drives the second piston 2304 to move upward in the inner cavity of the second through pipe 2303. The sliding connection between the vertical rod 2307 and the upper protective box 12 also guides the moving trajectory of the second piston 2304, thereby increasing the stability of the second piston 2304 when it moves upward. The upward movement of the second piston 2304 extracts air from the inner cavity of the second through pipe 2303, and a channel is formed between the second through pipe 2303, the heat dissipation pipe 2301 and the first through pipe 2302. When the second piston 2304 moves upward, , the air at the port of the first through pipe 2302 is extracted, and the extracted air enters the inner cavity of the heat dissipation pipe 2301 to replace the hot air. A through hole 2305 is opened at the bottom of the second piston 2304. When the second piston 2304 moves up to the maximum distance, the through hole 2305 is exposed to the air, and the hot air extracted by the second piston 2304 is released. When the second piston 2304 moves up, the third spring 2314 is stretched. When the second piston 2304 loses the upward driving force, the reaction force of the third spring 2314 drives the second piston 2304 to return to the second through pipe 23 03, during the downward movement, the inner cavity of the second through-tube 2303 is squeezed to squeeze the air in the second through-tube 2303, so that the hot air overflows through the port of the first through-tube 2302, thereby realizing the continuous replacement of the hot air in the heat dissipation pipe 2301, and improving the cooling of the heated heat-conducting oil in the copper conduit 2213; when the lever plate 2309 is pressed down to an appropriate distance, the lever plate 2309 is disengaged from the gear 2208, that is, one end of the lever plate 2309 loses the downward pressure, and at this time, the reaction force of the second spring 2310 realizes the reset of the rotation angle of the lever plate 2309, so that one end of the lever plate 2309 is meshed with the gear 2208 again.

A method for using a cable joint temperature monitoring device according to any one of claims 1 to 7, Features: The specific steps include: S1: When protecting the cable joint, the two connected cables are clamped in the inner cavity of the lower protection box (11). The cable joint is located in the middle of the inner cavity of the lower protection box (11). Before connecting the two cables, one of the cables is passed through the inner ring of the oil storage ring (2101) and then connected to the other cable. When the cable passes through the inner cavity of the oil storage ring (2101), the curved plate (2104) is elastically adjusted to extend the distance through the spring telescopic rod (2103), so that the curved plate (2104) can fit on the surface of the cable. When the curved plate (2104) is well fitted, the temperature sensing drive unit (22) is also fitted on the surface of the cable. After the connection of the two cables is completed, the curved plate (2104), the temperature sensing drive unit (22) and the surface of the cable joint are adjusted. The upper protective box (12) and the lower protective box (11) are fitted together, and then the upper protective box (12) and the lower protective box (11) are fixed by bolts. The assembled upper protective box (12) and the lower protective box (11) are collectively referred to as a box body. The assembled box body is then fixed together. The surface of the lower protective box (11) is provided with air holes to facilitate heat dissipation in the inner cavity of the box body. The inner cavity of the oil storage ring (2101) is filled with heat transfer oil. When high temperature is generated at the cable joint, the high temperature is transferred to the spring telescopic rod (2103) through the curved plate (2104), and then transferred to the oil storage ring (2101), and then transferred to the heat transfer oil in the inner cavity of the oil storage ring (2101). The spring telescopic rod (2103) and the oil storage ring (2101) are both made of copper, which can increase heat transfer. The high temperature at the cable joint can be effectively reduced by the cooled heat transfer oil. S2: When high temperature is generated at the cable joint, the high temperature heats the gas storage tube (2201), and the helium in the gas storage tube (2201) expands due to the heat, pushing the first piston (2202). The movement of the first piston (2202) drives the magnetic block (2203) to move. The magnetic block (2203) and the magnetic ring (2204) are in a magnetic attraction state. The movement of the magnetic block (2203) drives the magnetic ring (2204) to move in the same direction. The movement of the magnetic ring (2204) drives the toothed plate (2205) to move. The movement of the toothed plate (2205) drives the gear (2208) meshing therewith, so that the gear (2208) rotates. The rotation of the gear (2208) drives the rotating column (2207) to rotate. The rotation of the rotating column (2207) The rotating disk (2210) is driven to rotate. The rotation of the rotating disk (2210) drives the two extrusion wheels (2211) to rotate. The extrusion wheels (2211) cooperate with the extrusion shell (2209) to extrude the first hose (2212) while rotating, so that a negative pressure area is formed in the inner cavity of the first hose (2212), and the heat transfer oil in the oil storage ring (2101) is absorbed.

When the gear (2208) rotates, one end of the lever plate (2309) is pressed down, and the other end of the lever plate (2309) rises. At this time, the second spring (2310) is stretched. When the other end of the lever plate (2309) rises, the bottom of the vertical rod (2307) is lifted, so that the vertical rod (2307) moves vertically upward. The contact area between the lever plate (2309) and the vertical rod (2307) is sufficient to ensure that the lever plate (2309) will not come into contact with the vertical rod (2307) when it rises. 7), the upward movement of the vertical rod (2307) drives the limit plate (2306) to move upward, and the upward movement of the limit plate (2306) drives the second piston (2304) to move upward in the inner cavity of the second through tube (2303).

The upward movement of the second piston (2304) extracts air from the inner cavity of the second through tube (2303), and a channel is formed between the second through tube (2303), the heat dissipation tube (2301) and the first through tube (2302). When the second piston (2304) is in a closed position, the air in the inner cavity of the second through tube (2303) is drawn out. ) moves upward, the air at the port of the first through pipe (2302) is extracted, and the extracted air enters the inner cavity of the heat dissipation pipe (2301) to replace the hot air. A through hole (2305) is opened at the bottom of the second piston (2304). When the second piston (2304) moves upward to the maximum distance, the through hole (2305) is exposed to the air, and the hot air extracted by the second piston (2304) is released. When the second piston (2304) moves upward, the third spring (2314) is stretched. When the second piston (2304) loses the upward driving force, the reaction force of the third spring (2314) drives the second piston (2304) to return to the second through pipe ( The inner cavity of the lever plate (2309) squeezes the air in the second through-tube (2303) during the downward movement, so that the hot air overflows through the port of the first through-tube (2302), thereby realizing the continuous replacement of the hot air in the heat dissipation pipe (2301), and improving the cooling of the heat-conducting oil in the copper conduit (2213). When the lever plate (2309) is pressed down to a certain distance, the lever plate (2309) is out of contact with the gear (2208), that is, one end of the lever plate (2309) loses the downward pressure. At this time, the reaction force of the second spring (2310) realizes the reset of the rotation angle of the lever plate (2309), so that one end of the lever plate (2309) is meshed with the gear (2208) again.
