[0038] ​The input end of the inner end trigger acquisition unit is signal connected with the outer heat induction sleeve 2, the input end of the outer end trigger acquisition unit is signal connected with the inner heat induction sleeve 4, the input ends of the liquid cooling parameter acquisition unit and the cable parameter acquisition unit are signal connected with the signal input port arranged on the heat-resistant cable maintenance station 9, the output end of the liquid cooling adjustment unit is signal connected with the liquid cooling circulation structure arranged on the rear side of the heat-resistant cable maintenance station 9, and the liquid cooling circulation structure is connected with the outer liquid cooling layer 12 and the inner liquid cooling layer 13 respectively, the output end of the protection data transmission unit is signal connected with the signal output port arranged on the heat-resistant cable maintenance station 9, through the cooperation of the outer heat induction sleeve 2, the two-way isolation sleeve 3, the inner heat induction sleeve 4, the trigger column 5 and the heat-resistant protection system, on the one hand, the temperature inside and outside the heat-resistant cable body 1 can be controlled, the influence of the external temperature or the internal use temperature on the heat-resistant cable body 1 is reduced, the stability and safety of the heat-resistant cable body 1 are promoted, on the other hand, when the temperature outside or inside the heat-resistant cable body 1 changes suddenly, the trigger induction can be generated in time, the real-time monitoring effect is achieved, the overheat of the heat-resistant cable body 1 can be protected in time, the application effect of the outer liquid cooling layer 12 and the inner liquid cooling layer 13 is promoted, the timeliness of the heat-resistant cable body 1 in response to the temperature change inside and outside is promoted, the damage of the heat-resistant cable body 1 caused by overheat is reduced, the service life of the heat-resistant cable body 1 is ensured, the stability and safety of the heat-resistant cable body 1 in the high-temperature environment are promoted, the heat-resistant cable body 1 can be regulated and controlled through the overheat factor, the heat dissipation effect is promoted, the damage of the heat-resistant cable body 1 caused by temperature is reduced, the effective overheat protection is achieved, the energy loss is effectively reduced, the environmental protection of the heat-resistant cable body 1 is promoted, and the heat dissipation effect is further promoted through the separation effect of the liquid cooling effect.

[0039] It should be noted that the liquid cooling circulation structure is prior art, the present embodiment is directly quoted, and no change is made to the principle and structure, such as the liquid cooling circulation structure including a circulating pump, a cooling liquid storage tank, a heat exchanger and the like, which can be purchased and selected by those skilled in the art according to actual needs, and details are not repeated here. The stiffness coefficient of the outer heat induction sleeve 2 is equal to the stiffness coefficient of the inner heat induction sleeve 4, and the stiffness coefficient of the outer heat induction sleeve 2 is less than the stiffness coefficient of the outer liquid cooling layer 12 and the protective outer layer 11, so that when thermal expansion occurs in the outer heat deformation cavity 21, the two-way isolation sleeve 3 will first act on the inner heat induction sleeve 4, driving the inner heat induction sleeve 4 to deform; the stiffness coefficient of the inner heat induction sleeve 4 is less than the stiffness coefficient of the inner liquid cooling layer 13, the isolation layer 14 and the cable core 15, so that when thermal expansion occurs in the inner heat deformation cavity 41, the two-way isolation sleeve 3 will first act on the outer heat induction sleeve 2, driving the outer heat induction sleeve 2 to deform.

[0040] Figure 3 - Figure 9The outer heat induction sleeve 2 is provided with an outer heat deformation cavity 21, and an outer trigger patch 6 is fixedly connected to the inner wall of the outer heat deformation cavity 21 away from the cable core 15. The outer trigger patch 6 cooperates with the end of the trigger column 5 away from the cable core 15. The input end of the inner end trigger acquisition unit is signal-connected with the outer trigger patch 6. Through the cooperation of the trigger column 5 and the outer trigger patch 6, the temperature sensing state of the inner heat induction sleeve 4 can be triggered and transmitted. When the overheat problem caused by the operation of the cable core 15 in the high-temperature-resistant cable body 1 is generated, the heat dissipation and circulation effect of the inner liquid cooling layer 13 can be enhanced, so that the overheat protection of the cable core 15 is realized, the communication damage and unstable operation caused by high temperature are reduced, and the safety of the high-temperature-resistant cable body 1 during operation is ensured.

[0041] Figure 3 - Figure 9 The inner heat induction sleeve 4 is provided with an inner heat deformation cavity 41, and an inner trigger patch 7 is fixedly connected to the inner wall of the inner heat deformation cavity 41 close to the cable core 15. The inner trigger patch 7 cooperates with the end of the trigger column 5 close to the cable core 15. The input end of the outer end trigger acquisition unit is signal-connected with the inner trigger patch 7. Through the cooperation of the trigger column 5 and the inner trigger patch 7, the temperature sensing state of the outer heat induction sleeve 2 can be triggered and transmitted. When the temperature is too high outside the high-temperature-resistant cable body 1, the heat dissipation and circulation effect of the outer liquid cooling layer 12 can be enhanced, so that the overheat protection of the high-temperature-resistant cable body 1 is realized, the effective temperature blocking effect is achieved, the damage of the high-temperature-resistant cable body 1 caused by continuous temperature conduction is avoided, and the liquid cooling circulation efficiency of the outer liquid cooling layer 12 and the inner liquid cooling layer 13 can be effectively and reasonably utilized. While ensuring the stability of the high-temperature-resistant cable body 1, the energy consumption is reduced, the cost of heat dissipation and maintenance is reduced, the green environmental protection of the operation of the high-temperature-resistant cable body 1 is improved, the high-temperature resistance of the high-temperature-resistant cable body 1 is promoted, and the economic benefits of the application of the high-temperature-resistant cable body 1 are promoted.

[0042] Figure 4 - Figure 9 The outer heat deformation cavity 21 is filled with an outer heat deformation medium, and the filling saturation of the outer heat deformation medium in the outer heat deformation cavity 21 under normal temperature conditions is 50%-60%. Figure 4 - Figure 9 The inner heat deformation cavity 41 is filled with an inner heat deformation medium, and the filling saturation of the inner heat deformation medium in the inner heat deformation cavity 41 under normal temperature conditions is 50%-60%. The outer heat deformation medium and the inner heat deformation medium are inert gases with thermal expansion properties, which can protect the application safety of the high-temperature-resistant cable body 1 while generating thermal expansion deformation effect. The semi-saturation filling mode can effectively promote the effectiveness of the deformation sensing of the outer heat induction sleeve 2 and the inner heat induction sleeve 4, and ensure the safety of thermal deformation triggering.

[0043] Figure 1 -Figure 9 Before the application of the high-temperature-resistant cable body 1, the cable technician inputs the parameter data of the high-temperature-resistant cable body 1 at this time through the signal input port on the heat-resistant cable maintenance station 9 to the cable parameter acquisition unit, including but not limited to the wire diameter of the high-temperature-resistant cable body 1, the application environment data of the high-temperature-resistant cable body 1, and the rated application temperature and other parameter data, and inputs the data of the liquid cooling to the liquid cooling parameter acquisition unit, including but not limited to the circulation space data of the outer liquid cooling layer 12 and the inner liquid cooling layer 13, the rated power of the liquid cooling circulation structure, the daily operation power, the overheat protection operation power, and other liquid cooling data. The cable parameter acquisition unit and the liquid cooling parameter acquisition unit transmit these basic data to the heat-resistant protection processing unit, and the heat-resistant protection processing unit analyzes and processes these data;

[0044] Then in the application process of the high-temperature-resistant cable body 1, the heat-resistant protection processing unit transmits the liquid cooling regulation signal to the liquid cooling regulation unit according to the parameter setting, so that the liquid cooling regulation unit controls the action of the liquid cooling circulation structure, so that the circulation cooling effect is generated in the outer liquid cooling layer 12 and the inner liquid cooling layer 13, which can absorb the heat inside and outside the high-temperature-resistant cable body 1, thereby ensuring the application stability of the high-temperature-resistant cable body 1 in the high-temperature environment, promoting its high-temperature resistance, and reducing the communication damage of the high-temperature-resistant cable body 1 caused by high temperature.

[0045] When the temperature inside and outside the high-temperature-resistant cable body 1 does not change, the liquid cooling circulation effect of the outer liquid cooling layer 12 and the inner liquid cooling layer 13 can effectively realize the heat dissipation and cooling effect of the high-temperature-resistant cable body 1, so that the outer heat deformation medium in the outer heat deformation cavity 21 of the outer heat induction sleeve 2 and the inner heat deformation medium in the inner heat deformation cavity 41 of the inner heat induction sleeve 4 do not produce a large deformation effect, thereby the outer heat induction sleeve 2 and the inner heat induction sleeve 4 form a balanced state under the elastic retention effect of the outer heat induction sleeve 2 and the inner heat induction sleeve 4, thereby the bidirectional spacer sleeve 3 and the trigger column 5 are in the central position between the outer heat induction sleeve 2 and the inner heat induction sleeve 4, thereby not contacting the outer trigger patch 6 or the inner trigger patch 7, indicating that the heat dissipation state is good at this time, which can ensure the stability and safety of the operation of the high-temperature-resistant cable body 1 through smaller circulation power, and reduce the energy loss and waste;

[0046] When the high temperature changes in the external environment of the high-temperature-resistant cable body 1, the outer heat deformation medium in the outer heat deformation cavity 21 of the outer heat induction sleeve 2 continuously absorbs heat to produce thermal expansion changes, which causes the thermal expansion deformation of the outer heat deformation cavity 21. Therefore, the elastic deformation of the outer heat induction sleeve 2 extrudes the bidirectional spacer sleeve 3 and the inner heat induction sleeve 4. When the bidirectional spacer sleeve 3 continuously approaches the inner heat induction sleeve 4 and extrudes the inner heat induction sleeve 4, the trigger column 5 approaches the end of the cable core 15 and abuts against the inner trigger patch 7. Then, the outer end trigger acquisition unit receives the trigger signal transmitted by the inner trigger patch 7 and transmits it to the heat-resistant protection processing unit. The heat-resistant protection processing unit determines that the temperature outside the high-temperature-resistant cable body 1 is high at this time, and then sends a control instruction to the liquid cooling adjustment unit, so that it controls the liquid cooling circulation structure to act on the outer liquid cooling layer 12, increases the circulation efficiency of the cooling liquid in the outer liquid cooling layer 12, promotes the heat dissipation effect of the high-temperature-resistant cable body 1 outside, effectively blocks the transmission of external temperature, and ensures the stability of the operation of the high-temperature-resistant cable body 1.

[0047] When the high temperature changes in the internal environment of the high-temperature-resistant cable body 1, the inner heat deformation medium in the inner heat deformation cavity 41 of the inner heat induction sleeve 4 continuously absorbs heat to produce thermal expansion changes, which drives the inner heat deformation cavity 41 to produce thermal expansion deformation. Therefore, the elastic deformation of the inner heat induction sleeve 4 acts on the bidirectional spacer sleeve 3, so that the bidirectional spacer sleeve 3 continuously approaches the outer heat induction sleeve 2 and extrudes the outer heat induction sleeve 2. In the process of continuously extruding the outer heat induction sleeve 2, the outer heat induction sleeve 2 continuously shrinks, causing the trigger column 5 to move away from the end of the cable core 15 and abut against the outer trigger patch 6. Then, the inner end trigger acquisition unit receives the trigger signal transmitted by the outer trigger patch 6 and transmits it to the heat-resistant protection processing unit. The heat-resistant protection processing unit determines that the temperature inside the high-temperature-resistant cable body 1 is high at this time, and then sends a control instruction to the liquid cooling adjustment unit, so that it controls the liquid cooling circulation structure to act on the inner liquid cooling layer 13, increases the circulation efficiency of the cooling liquid in the inner liquid cooling layer 13, increases the heat dissipation effect of the high-temperature-resistant cable body 1 inside, reduces the damage of temperature to the cable core 15, ensures the effectiveness and stability of the operation of the cable core 15, and avoids the communication fluctuation problem caused by the increase of temperature;

[0048] In the process of heat-resistant protection unit for high temperature cable body 1 operation protection and overheat protection, the protection process control data will be transmitted to the protection data transmission unit, the protection data transmission unit will output the data through the signal output port of the heat-resistant cable maintenance station 9, which is convenient for technicians and maintenance personnel to check the state data of the high temperature cable body 1 and protection data, so as to facilitate the technicians to adaptively improve the high temperature cable body 1 and liquid cooling program, promote the safety and effectiveness of the high temperature cable body 1, and facilitate the maintenance personnel to judge the state of the high temperature cable body 1 according to the data, so as to make effective maintenance measures and actions, and realize the safety protection of the high temperature cable body 1.

[0049] The second embodiment:

[0050] Figure 1 - Figure 12 The overheat protection type high temperature cable is shown, which is further improved and increased as the first embodiment function, further increases the intelligence of the first embodiment, is an optional item, increases the multi-specification of the first embodiment, and demand adaptability, the trigger column 5 is provided with a buffer sensing cavity, a trigger core block 83 is fixedly connected in the middle of the buffer sensing cavity, and the buffer sensing cavity is provided with overheat conducting columns 8 on the inner wall close to the cable core 15 and the inner wall away from the cable core 15. The two overheat conducting columns 8 extend to the buffer sensing cavity at the close end and cooperate with the trigger core block 83. The arrangement of the overheat conducting column 8 and the trigger core block 83 can realize the sensing and detection of the trigger state of the trigger column 5, effectively realize the verification of the overheat protection measure effect, ensure the adjustment and effectiveness of the overheat protection, further ensure the stability and safety of the high temperature cable body 1 operation, and promote the automation and intelligence of the heat protection system, improve the maintenance effect of the high temperature cable body 1, and promote the self-checking and self-adjusting effect.

[0051] Figure 10 - Figure 12 The overheat conducting column 8 is fixedly connected with a blocking ring 81 in the buffer sensing cavity, and the blocking ring 81 is in sliding cooperation with the inner wall of the buffer sensing cavity. The blocking ring 81 is fixedly connected with an elastic reset member 82 sleeved on the outer side of the overheat conducting column 8 at the end close to the trigger core block 83, and the elastic reset member 82 is fixedly connected with the trigger core block 83 at the end close to the trigger core block 83. The arrangement of the blocking ring 81 and the elastic reset member 82 can increase the reset effect after the trigger of the overheat conducting column 8 and the trigger core block 83, ensure the effectiveness and sensitivity of the verification trigger, and reduce the preparation cost of the high temperature cable body 1 through mechanical reset, promote the economic benefit of the high temperature cable body 1.

[0052] Figure 2 and Figure 10 - Figure 12The input end of the heat-resistant protection processing unit is also connected with an inner end heat persistence feedback unit and an outer end heat persistence feedback unit, the input ends of the inner end heat persistence feedback unit and the outer end heat persistence feedback unit are in signal connection with the trigger core block 83, the output end of the heat-resistant protection processing unit is connected with a heat persistence alarm unit, the output end of the heat persistence alarm unit is in signal connection with an alarm arranged on the heat-resistant cable maintenance station 9, and the cooperation of the inner end heat persistence feedback unit and the outer end heat persistence feedback unit can further play the roles of overheat protection, heat dissipation verification and continuous overheat early warning for the heat-resistant cable body 1, can effectively guarantee the stability and safety of the heat-resistant cable body 1 in operation, and can assist maintenance personnel and relevant technical personnel to timely process the overheat abnormality of the heat-resistant cable body 1, thereby reducing economic losses caused by continuous overheat.

[0053] Figure 1 - Figure 12 When the heat-resistant protection processing unit controls the liquid cooling regulation unit through the data transmitted by the outer end trigger collection unit after the high-temperature change of the external environment, and the overheat protection regulation is effective, the temperature of the outer heat induction sleeve 2 is restored, the volume of the outer heat deformation medium in the outer heat deformation cavity 21 is restored, the thermal expansion effect on the outer heat deformation cavity 21 is removed, and the bidirectional spacer 3 and the inner heat induction sleeve 4 are gradually restored under the elastic recovery of the outer heat induction sleeve 2 and the inner heat induction sleeve 4, the trigger column 5 is away from the inner trigger patch 7, the outer end trigger collection unit no longer receives the outer trigger signal and transmits it to the heat-resistant protection processing unit, the heat-resistant protection processing unit judges that the overheat protection regulation is effective at this time, then controls the liquid cooling circulation structure to act on the outer liquid cooling layer 12 for a period of time, sends a recovery liquid cooling regulation instruction to the liquid cooling regulation unit, controls the liquid cooling circulation structure to restore the liquid cooling circulation power of the outer liquid cooling layer 12, and then restores to the normal liquid cooling state, and then judges the recovery state of the external environment of the heat-resistant cable body 1 according to the signals transmitted by the subsequent outer end trigger collection unit. When the above overheat protection effect cycle occurs continuously for multiple times in the subsequent application process of the heat-resistant cable body 1, the heat-resistant protection processing unit sends an alarm signal to the heat persistence alarm unit, so that the alarm arranged on the heat-resistant cable maintenance station 9 is started to alarm and remind the maintenance personnel, so as to remind the maintenance personnel to check and maintain the application of the heat-resistant cable body 1, and guarantee the safety of the subsequent application of the heat-resistant cable body 1.

[0054] When the overheat protection regulation is invalid, the outer heat induction sleeve 2 keeps the continuous thermal expansion effect under the action of the outer heat deformation medium, and further extrusion is generated on the bidirectional isolation sleeve 3 and the inner heat induction sleeve 4. At this time, the trigger column 5 is close to one end of the cable core 15, and the abutting effect of the inner trigger patch 7 generates extrusion on the overheat conductive column 8 located in the trigger column 5. The elastic reset member 82 is compressed under the action of the blocking ring 81, and the other end of the overheat conductive column 8 abuts against the trigger core block 83. At this time, the outer end heat continuous feedback unit receives the abutting signal of the trigger core block 83 close to one side of the cable core 15, and then transmits the data to the heat-resistant protection processing unit. The heat-resistant protection processing unit judges that the temperature change of the outside of the high-temperature-resistant cable body 1 is abnormal at this time, and then transmits the overheat continuous abnormal alarm data to the heat continuous alarm unit, so that the heat continuous alarm unit controls the alarm in the heat-resistant cable maintenance station 9 to start, and sends an alarm to the maintenance personnel, prompting them to respond to the emergency. At the same time, the heat-resistant protection processing unit also sends a continuous enhanced liquid cooling regulation instruction to the liquid cooling regulation unit, so that the liquid cooling regulation unit controls the liquid cooling circulation structure to act on the outer liquid cooling layer 12, further increases the heat absorption circulation effect of the outer liquid cooling layer 12, and strives for effective time for maintenance personnel to repair and check, thereby effectively reducing economic losses.

[0055] When the internal environment changes in temperature, after the heat-resistant protection processing unit controls the liquid cooling regulation unit through the data transmitted by the outer end trigger collection unit, when the overheat protection regulation is effective, the temperature of the inner heat induction sleeve 4 continuously recovers, causing the volume recovery change of the inner heat deformation medium in the inner heat deformation cavity 41, and the thermal expansion effect on the inner heat deformation cavity 41 is released. Under the elastic recovery effect of the outer heat induction sleeve 2 and the inner heat induction sleeve 4, the bidirectional isolation sleeve 3 and the outer heat induction sleeve 2 gradually recover the deformation, the trigger column 5 moves away from the outer trigger patch 6, the inner end trigger collection unit no longer receives the inner trigger signal and transmits it to the heat-resistant protection processing unit. The heat-resistant protection processing unit judges that the overheat protection regulation is effective at this time, and then sends a recovery liquid cooling regulation instruction to the liquid cooling regulation unit after the liquid cooling circulation structure controls the inner liquid cooling layer 13 for a period of time, so that the liquid cooling regulation unit controls the liquid cooling circulation structure to restore the liquid cooling circulation power of the inner liquid cooling layer 13, so that it returns to the normal liquid cooling state. Then, according to the signal transmitted by the subsequent inner end trigger collection unit, the recovery state of the internal environment of the high-temperature-resistant cable body 1 is judged. When the above overheat protection effect cycle occurs continuously for multiple times in the subsequent application process of the high-temperature-resistant cable body 1, the heat-resistant protection processing unit sends an alarm signal to the heat continuous alarm unit, so that the alarm in the heat-resistant cable maintenance station 9 starts, and sends an alarm to the maintenance personnel, prompting the maintenance personnel to check and maintain the application of the high-temperature-resistant cable body 1, check whether the high-temperature-resistant cable body 1 is overloaded, and ensure the safety of the subsequent application of the high-temperature-resistant cable body 1;

[0056] When the overheat protection regulation is invalid, the inner heat induction sleeve 4 keeps the thermal expansion effect under the action of the inner heat deformation medium, and further extrusion is generated on the bidirectional spacer sleeve 3 and the outer heat induction sleeve 2. At this time, the trigger column 5 far away from one end of the cable core 15 is in abutting action with the outer trigger patch 6, which extrudes the overheat conducting column 8 located in the trigger column 5. The elastic reset member 82 is compressed under the action of the blocking ring 81, and the other end of the overheat conducting column 8 abuts against the trigger core block 83. At this time, the inner end heat continuous feedback unit receives the abutting signal of the trigger core block 83 close to one side of the cable core 15, and then transmits the data to the heat-resistant protection processing unit. The heat-resistant protection processing unit judges that the temperature change in the high-temperature resistant cable body 1 is abnormal at this time, and then transmits the overheat continuous abnormal alarm data to the heat continuous alarm unit, so that the heat continuous alarm unit controls the alarm in the heat-resistant cable maintenance station 9 to start, and sends an alarm to the maintenance personnel to promote the emergency response. At the same time, the heat-resistant protection processing unit also sends the continuous enhanced liquid cooling regulation instruction to the liquid cooling regulation unit, so that the liquid cooling regulation unit controls the liquid cooling circulation structure to act on the inner liquid cooling layer 13, further increases the heat absorption circulation effect of the inner liquid cooling layer 13, and strives for effective time for the maintenance personnel to repair and check, thereby effectively reducing the economic loss.
