DETAILED DESCRIPTION

[0018] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0019] The first implementation method: Figure 1 - Fig. 9 An overheat protection type high temperature resistant cable is shown, comprising a high temperature resistant cable body 1 and a heat resistant cable maintenance station 9 matched with the high temperature resistant cable body 1, wherein the high temperature resistant cable body 1 comprises a cable core 15, an isolation layer 14 fixedly sleeved on the outer end of the cable core 15, an inner liquid cooling layer 13 fixedly sleeved on the outer end of the isolation layer 14, an outer liquid cooling layer 12 arranged on the outer side of the inner liquid cooling layer 13, and a protective outer layer 11 fixedly sleeved on the outer end of the outer liquid cooling layer 12; The outer end of the inner liquid cooling layer 13 is fixedly sleeved with an inner heat induction sleeve 4, the outer end of the inner heat induction sleeve 4 is fixedly sleeved with a bidirectional spacer sleeve 3, the outer end of the bidirectional spacer sleeve 3 is fixedly sleeved with an outer heat induction sleeve 2, and the outer end of the outer heat induction sleeve 2 is fixedly connected to the outer liquid cooling layer 12, and a plurality of triggering columns 5 are embedded on the bidirectional spacer sleeve 3, the triggering columns 5 extend from one end of the cable core 15 to the inner heat induction sleeve 2 and cooperate with the outer heat induction sleeve 2, and the triggering columns 5 extend from one end of the cable core 15 to the inner heat induction sleeve 4 and cooperate with the inner heat induction sleeve 4; A heat-resistant protection system is provided in the heat-resistant cable maintenance station 9, and the heat-resistant protection system includes a heat-resistant protection processing unit, the input end of the heat-resistant protection processing unit is connected to an inner end trigger collection unit, an outer end trigger collection unit, a liquid cooling parameter collection unit and a cable parameter collection unit, and the output end of the heat-resistant protection processing unit is connected to a liquid cooling adjustment unit and a protection data transmission unit; The input end of the inner trigger acquisition unit is connected to the signal of the outer heat induction sleeve 2, the input end of the outer trigger acquisition unit is connected to the signal of the inner heat induction sleeve 4, the input ends of the liquid cooling parameter acquisition unit and the cable parameter acquisition unit are both connected to the signal input port arranged on the heat-resistant cable maintenance station 9, the output end of the liquid cooling adjustment unit is connected to the signal of 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 respectively connected and coordinated with the outer liquid cooling layer 12 and the inner liquid cooling layer 13, the output end of the protection data transmission unit is connected to the signal output port arranged on the heat-resistant cable maintenance station 9, through the cooperation of the outer heat induction sleeve 2, the bidirectional spacer sleeve 3, the inner heat induction sleeve 4, the trigger column 5 and the heat-resistant protection system, it is possible to maintain the control of the internal and external temperatures of the high-temperature resistant cable body 1 during its use, reduce the influence of the external temperature or the internal operating temperature on the high-temperature resistant cable body 1, and promote the stability and safety of the operation of the high-temperature resistant cable body 1. On the one hand, it can generate trigger induction in time when the external or internal temperature of the high-temperature resistant cable body 1 changes suddenly. While playing a real-time monitoring role, it can also protect the high-temperature resistant cable body 1 from overheating in time, promote the application effect of the outer liquid cooling layer 12 and the inner liquid cooling layer 13, and promote its timely response to the temperature changes inside and outside the high-temperature resistant cable body 1, reduce the damage of the high-temperature resistant cable body 1 caused by overheating, and ensure the service life of the high-temperature resistant cable body 1. At the same time, it promotes the stability and safety of the operation of the high-temperature resistant cable body 1 in a high-temperature environment, and can regulate the liquid cooling cycle in a targeted manner through the overheating factor, while promoting the heat dissipation effect and reducing the damage to the high-temperature resistant cable body 1 caused by temperature, and plays an effective overheating protection. At the same time, it can also effectively reduce energy loss, promote the environmental protection of the application of the high-temperature resistant cable body 1, and further promote the heat dissipation effect through the separation effect of the liquid cooling effect.

[0020] It should be noted that the liquid cooling circulation structure is a prior art, and this embodiment is a direct reference, and no changes are made to its principle and structure. For example, the liquid cooling circulation structure includes components such as a circulation pump, a coolant storage tank, and a heat exchanger. Those skilled in the art can purchase and select them according to actual needs, and they will not be described here. The stiffness coefficient of the outer thermal induction sleeve 2 is equal to the stiffness coefficient of the inner thermal induction sleeve 4, and the stiffness coefficient of the outer thermal induction sleeve 2 is less than the stiffness coefficient of the outer liquid cooling layer 12 and the protective outer layer 11. When the outer thermal deformation cavity 21 produces thermal expansion, the bidirectional spacer sleeve 3 will first act on the inner thermal induction sleeve 4, causing the inner thermal induction sleeve 4 to deform; the stiffness coefficient of the inner thermal 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. When the inner thermal deformation cavity 41 produces thermal expansion, the bidirectional spacer sleeve 3 will first act on the outer thermal induction sleeve 2, causing the outer thermal induction sleeve 2 to deform.

[0021] Figure 3 - Fig. 9 It is shown that an external thermal deformation cavity 21 is opened in the external thermal sensing sleeve 2, and an external trigger patch 6 is fixedly connected to the inner wall of the external thermal deformation cavity 21 away from the cable core 15. The external trigger patch 6 cooperates with the end of the trigger column 5 away from the cable core 15, and the input end of the inner end trigger acquisition unit is connected with the external trigger patch 6 signal. Through the cooperation of the trigger column 5 and the external trigger patch 6, the temperature sensing state of the internal thermal sensing sleeve 4 can be triggered and transmitted, which is convenient for enhancing the heat dissipation circulation effect of the internal liquid cooling layer 13 when the overheating problem is caused by the operation of the cable core 15 inside the high-temperature resistant cable body 1, thereby realizing overheating protection of the cable core 15, reducing communication damage and unstable operation caused by high temperature, and ensuring the safety of the high-temperature resistant cable body 1 during operation.

[0022] Figure 3 - Fig. 9 It is shown that an inner thermal deformation cavity 41 is provided in the inner thermal sensing sleeve 4, and an inner trigger patch 7 is fixedly connected to the inner wall of the inner thermal deformation cavity 41 near the cable core 15. The inner trigger patch 7 cooperates with the end of the trigger column 5 near the cable core 15, and the input end of the external trigger acquisition unit is connected to the signal of 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 external thermal sensing sleeve 2 can be triggered and transmitted, so that when the temperature outside the high temperature resistant cable body 1 is too high, the heat dissipation circulation effect of the outer liquid cooling layer 12 is enhanced, so as to realize overheating protection of the high temperature resistant cable body 1, play an effective temperature barrier role, avoid the damage of the high temperature resistant cable body 1 caused by continuous temperature conduction, and can also effectively and reasonably utilize the liquid cooling circulation efficiency of the outer liquid cooling layer 12 and the inner liquid cooling layer 13, while ensuring the operating stability of the high temperature resistant cable body 1, reduce energy loss, reduce the cost of heat dissipation maintenance, improve the green environmental protection of the operation of the high temperature resistant cable body 1, promote the high temperature resistance of the high temperature resistant cable body 1, and promote the economic benefits of the application of the high temperature resistant cable body 1.

[0023] Figure 4 - Fig. 9 It is shown that the external thermal deformation cavity 21 is filled with an external thermal deformation medium, and the filling saturation of the external thermal deformation medium in the external thermal deformation cavity 21 is 50% to 60% under normal temperature. Figure 4 - Fig. 9 It is shown that the inner thermal deformation cavity 41 is filled with an inner thermal deformation medium, and the filling saturation of the inner thermal deformation medium in the inner thermal deformation cavity 41 is 50% to 60% at room temperature. The outer thermal deformation medium and the inner thermal 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 and deformation effects. The semi-saturated filling method can also effectively promote the effectiveness of deformation induction of the outer thermal induction sleeve 2 and the inner thermal induction sleeve 4, and ensure the safety of thermal deformation triggering.

[0024] Figure 1 - Fig. 9 It is shown that before the high temperature resistant cable body 1 is applied, the cable technician inputs parameter data about the high temperature resistant cable body 1 at this time to the cable parameter acquisition unit through the signal input port on the heat resistant cable maintenance station 9, 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 at the same time inputs data about 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 operating power, the overheating protection operating 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; Then, during the application of the high-temperature resistant cable body 1, the heat-resistant protection processing unit transmits a liquid cooling control signal to the liquid cooling adjustment unit according to the parameter setting, so that the liquid cooling adjustment unit controls the action of the liquid cooling circulation structure, so that a circulating 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 a 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.

[0025] When the internal and external temperatures of the high-temperature resistant cable body 1 do not change, the liquid cooling circulation of the outer liquid cooling layer 12 and the inner liquid cooling layer 13 can effectively achieve the heat dissipation and cooling effect on the high-temperature resistant cable body 1. Therefore, the external heat deformation medium in the external heat deformation cavity 21 of the outer heat sensing sleeve 2 and the internal heat deformation medium in the internal heat deformation cavity 41 of the inner heat sensing sleeve 4 will not produce a large deformation effect. Then, under the elastic force of the outer heat sensing sleeve 2 and the inner heat sensing sleeve 4, the outer heat sensing sleeve 2 and the inner heat sensing sleeve 4 form a balanced state, so that the two-way spacer sleeve 3 and the trigger column 5 are located in the center between the outer heat sensing sleeve 2 and the inner heat sensing sleeve 4, and will not contact the outer trigger patch 6 or the inner trigger patch 7, indicating that the heat dissipation state is good at this time, and the stability and safety of the operation of the high-temperature resistant cable body 1 can be guaranteed by a smaller circulation power, thereby reducing energy loss and waste; When the external environment of the high temperature resistant cable body 1 produces a high temperature change, the external heat deformation medium in the external heat deformation cavity 21 of the external heat induction sleeve 2 continuously absorbs heat and produces a thermal expansion change, which acts on the external heat deformation cavity 21 to produce thermal expansion deformation. Therefore, the elastic deformation of the external heat induction sleeve 2 squeezes the bidirectional spacer sleeve 3 and produces an extrusion effect on the inner heat induction sleeve 4. When the bidirectional spacer sleeve 3 continuously approaches the inner heat induction sleeve 4 and produces an extrusion and contraction effect on the inner heat induction sleeve 4, the trigger column 5 is close to the end of the cable core 15 and abuts against the inner trigger patch 7. The external trigger acquisition unit receives the trigger signal transmitted by the internal trigger patch 7, and transmits it to the heat-resistant protection processing unit. The heat-resistant protection processing unit determines that the external temperature of the high-temperature resistant cable body 1 increases 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 external liquid cooling layer 12, increases the circulation efficiency of the coolant in the external liquid cooling layer 12, promotes its heat dissipation effect on the outside of the high-temperature resistant cable body 1, effectively blocks the transmission of the external temperature, and ensures the stability of the operation of the high-temperature resistant cable body 1; When the high temperature changes inside the high temperature resistant cable body 1 due to operation and other factors, the internal heat deformation medium in the internal heat deformation cavity 41 of the internal heat induction sleeve 4 continuously absorbs heat and produces thermal expansion changes, driving the internal heat deformation cavity 41 to produce thermal expansion deformation. Therefore, the elastic deformation of the internal heat induction sleeve 4 acts on the two-way spacer sleeve 3, so that the two-way spacer sleeve 3 continuously approaches the outer heat induction sleeve 2, and produces an extrusion effect on the outer heat induction sleeve 2. In the process of the two-way spacer sleeve 3 continuously squeezing the outer heat induction sleeve 2, the outer heat induction sleeve 2 continues to shrink, causing the end of the trigger column 5 away from the cable core 15 to abut against the external trigger patch 6, and then The inner trigger acquisition unit receives the trigger signal transmitted by the external trigger patch 6, and transmits it to the heat-resistant protection processing unit. The heat-resistant protection processing unit determines that the internal temperature of the high-temperature resistant cable body 1 increases 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 coolant in the inner liquid cooling layer 13, increases the heat dissipation effect inside the high-temperature resistant cable body 1, reduces the damage caused by the temperature to the cable core 15, ensures the effectiveness and stability of the operation and conduction of the cable core 15, and avoids communication fluctuation problems caused by temperature increase; During the process of the heat-resistant protection processing unit performing operation protection and overheat protection on the high-temperature resistant cable body 1, the control data in the protection process will be transmitted to the protection data transmission unit, and the protection data transmission unit will output the data through the signal output port of the heat-resistant cable maintenance station 9, so that technicians and maintenance personnel can view the status data of the high-temperature resistant cable body 1 and protection data, so that technicians can make adaptive improvements to the high-temperature resistant cable body 1 and the liquid cooling program, promote the safety and effectiveness of the use of the high-temperature resistant cable body 1, and facilitate maintenance personnel to judge the status of the high-temperature resistant cable body 1 according to the data, and make effective maintenance measures and actions to ensure the safety of the high-temperature resistant cable body 1.

[0026] Second implementation method: Figure 1 - Fig.12An overheat protection type high temperature resistant cable is shown, which is a further improvement and addition of the function of the first embodiment, further increasing the intelligence of the first embodiment. It is an optional option, increasing the multi-specification and demand adaptability of the first embodiment. A buffer sensing cavity is opened in the trigger column 5, and a trigger core block 83 is fixedly connected to the middle of the buffer sensing cavity. The inner wall of the buffer sensing cavity close to the cable core 15 and the inner wall of the buffer sensing cavity away from the cable core 15 are both embedded with overheat conduction columns 8. The two overheat conduction columns 8 extend into the buffer sensing cavity at one end close to each other and cooperate with the trigger core block 83. The setting of the overheat conduction column 8 and the trigger core block 83 can sense and detect the trigger state of the trigger column 5, and can effectively verify the effect of the overheat protection measures, ensure the adjustment and effectiveness of the overheat protection, further ensure the stability and safety of the operation of the high temperature resistant cable body 1, and also promote the automation and intelligence of the heat-resistant protection system, improve its maintenance effect on the high temperature resistant cable body 1, and promote its self-inspection and self-adjustment.

[0027] Fig.10 - Fig.12 It is shown that the outer end of the overheated conductive column 8 is fixedly connected to a baffle ring 81 located in the buffer sensing cavity, and the baffle ring 81 is in sliding cooperation with the inner wall of the buffer sensing cavity, and the baffle ring 81 is fixedly connected to an elastic reset member 82 sleeved on the outer side of the overheated conductive column 8 at one end close to the trigger core block 83, and the elastic reset member 82 is fixedly connected to the trigger core block 83 at one end close to the trigger core block 83. The setting of the baffle ring 81 and the elastic reset member 82 can increase the reset effect of the overheated conductive column 8 and the trigger core block 83 after being triggered, while ensuring the effectiveness and sensitivity of the verification trigger, it can also reduce the preparation cost of the high temperature resistant cable body 1 by mechanical reset, and promote the economic benefits of the high temperature resistant cable body 1.

[0028] Figure 2 and Fig.10 - Fig.12 It is shown that the input end of the heat-resistant protection processing unit is also connected to the inner end thermal continuous feedback unit and the outer end thermal continuous feedback unit, the input ends of the inner end thermal continuous feedback unit and the outer end thermal continuous feedback unit are connected to the trigger core block 83 signal, the output end of the heat-resistant protection processing unit is connected to the thermal continuous alarm unit, the output end of the thermal continuous alarm unit is connected to the alarm signal arranged on the heat-resistant cable maintenance station 9, the cooperation of the inner end thermal continuous feedback unit and the outer end thermal continuous feedback unit can further play the role of overheating protection, heat dissipation verification and continuous overheating warning for the high temperature resistant cable body 1, can effectively ensure the stability and safety of the operation of the high temperature resistant cable body 1, can assist maintenance personnel and relevant technical personnel to promptly deal with the overheating anomaly of the high temperature resistant cable body 1, and reduce the economic losses caused by the continuous overheating.

[0029] Figure 1 - Fig.12It is shown that when a high temperature change occurs in the external environment, the heat-resistant protection processing unit controls the liquid cooling control unit through the data transmitted by the external trigger acquisition unit. When the overheat protection control is effective, the temperature of the external heat sensing sleeve 2 is continuously restored, causing the external heat deformation medium in the external heat deformation cavity 21 to produce a volume recovery change, and the thermal expansion effect on the external heat deformation cavity 21 is released. Under the elastic recovery effect of the external heat sensing sleeve 2 and the internal heat sensing sleeve 4, the bidirectional spacer sleeve 3 and the internal heat sensing sleeve 4 produce a gradual recovery deformation, the trigger column 5 is away from the internal trigger patch 7, the external trigger acquisition unit no longer receives the external trigger signal, and transmits it to the heat-resistant protection processing unit. The heat-resistant protection processing unit determines that the overheat protection control is effective at this time, and then controls the external liquid cooling layer 12 in the liquid cooling circulation structure. After acting for a period of time, an adjustment instruction for restoring liquid cooling is sent to the liquid cooling adjustment unit, so that the liquid cooling adjustment unit controls the liquid cooling circulation structure to restore the liquid cooling circulation power of the outer liquid cooling layer 12, so that it returns to a normal liquid cooling state, and then judges the recovery state of the external environment of the high-temperature resistant cable body 1 according to the signal transmitted by the subsequent external end trigger acquisition unit. When the above-mentioned overheat protection action cycle occurs repeatedly 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 thermal continuous alarm unit, so that the alarm located on the heat-resistant cable maintenance station 9 is activated, and an alarm reminder is issued to the maintenance personnel, reminding the maintenance personnel to check and maintain the application of the high-temperature resistant cable body 1, so as to ensure the safety of the subsequent application of the high-temperature resistant cable body 1; When the overheat protection regulation is invalid, the outer thermal sensing sleeve 2 maintains continuous thermal expansion under the action of the external thermal deformation medium, and further squeezes the bidirectional spacer sleeve 3 and the inner thermal sensing sleeve 4. At this time, the end of the trigger column 5 close to the cable core 15 is squeezed by the abutment of the inner trigger patch 7, which squeezes the overheated conductive column 8 located in the trigger column 5, so that the elastic reset member 82 is compressed under the action of the baffle ring 81, and the other end of the overheated conductive column 8 is abutted against the trigger core block 83. At this time, the external end thermal continuous feedback unit receives the abutment signal of the trigger core block 83 close to the cable core 15 side, and then transmits the data to the heat-resistant protection processing unit. The protection processing unit determines that the external temperature change of the high-temperature resistant cable body 1 is abnormal at this time, and then transmits the abnormal alarm data of continuous overheating to the thermal continuity alarm unit, so that the thermal continuity alarm unit controls the alarm located on the heat-resistant cable maintenance station 9 to start, and sends an alarm reminder to the maintenance personnel to promote their emergency response. At the same time, the heat-resistant protection processing unit will also issue continuous enhanced liquid cooling control instructions to the liquid cooling adjustment unit, so that the liquid cooling adjustment unit controls the liquid cooling circulation structure to act on the outer liquid cooling layer 12, further increasing the heat absorption circulation effect of the outer liquid cooling layer 12, and gaining effective time for the maintenance personnel's emergency repairs and inspections, thereby effectively reducing economic losses.

[0030] When the temperature of the internal environment changes, the heat-resistant protection processing unit controls the liquid cooling control unit through the data transmitted by the external trigger acquisition unit. When the overheat protection control is effective, the temperature of the inner heat sensing sleeve 4 is continuously restored, causing the inner heat deformation medium in the inner heat deformation cavity 41 to produce a volume recovery change, thereby relieving the thermal expansion effect on the inner heat deformation cavity 41. Under the elastic recovery effect of the outer heat sensing sleeve 2 and the inner heat sensing sleeve 4, the bidirectional spacer sleeve 3 and the outer heat sensing sleeve 2 produce a gradual recovery deformation, the trigger column 5 moves away from the external trigger patch 6, the inner trigger acquisition unit no longer receives the internal trigger signal, and transmits it to the heat-resistant protection processing unit. The heat-resistant protection processing unit determines that the overheat protection control is effective at this time, and after the liquid cooling cycle structure controls the inner liquid cooling layer 13 to act for a period of time, the liquid cooling is The regulating unit sends out a regulating instruction for restoring liquid cooling, so that the liquid cooling regulating 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 a normal liquid cooling state, and then judges the recovery state of the internal environment of the high temperature resistant cable body 1 according to the signal transmitted by the subsequent inner end trigger acquisition unit. When the above-mentioned overheat protection action cycle occurs repeatedly 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 thermal continuous alarm unit, so that the alarm located on the heat-resistant cable maintenance station 9 is activated, and an alarm reminder is issued to the maintenance personnel, reminding the maintenance personnel to check and maintain the application of the high temperature resistant cable body 1, and check whether the high temperature resistant cable body 1 is overloaded, etc., to ensure the safety of the subsequent application of the high temperature resistant cable body 1; When the overheat protection regulation is invalid, the inner thermal sensing sleeve 4 maintains continuous thermal expansion under the action of the inner thermal deformation medium, and exerts further squeezing effect on the bidirectional spacer sleeve 3 and the outer thermal sensing sleeve 2. At this time, the end of the trigger column 5 away from the cable core 15 is abutted by the external trigger patch 6, which exerts squeezing effect on the overheated conductive column 8 located in the trigger column 5, so that the elastic reset member 82 is compressed under the action of the baffle ring 81, and the other end of the overheated conductive column 8 abuts against the trigger core block 83. At this time, the inner end thermal continuous feedback unit receives the abutment signal of the trigger core block 83 close to the cable core 15 side, and then transmits the data to the heat-resistant protection processing unit. The protection processing unit determines that the internal temperature change of the high-temperature resistant cable body 1 is abnormal at this time, and then transmits the abnormal alarm data of overheating to the thermal continuity alarm unit, so that the thermal continuity alarm unit controls the alarm located on the heat-resistant cable maintenance station 9 to start, and sends an alarm reminder to the maintenance personnel to promote their emergency response. At the same time, the heat-resistant protection processing unit will also send continuous enhanced liquid cooling control instructions to the liquid cooling adjustment unit, so that the liquid cooling adjustment unit controls the liquid cooling circulation structure to act on the inner liquid cooling layer 13, further increasing the heat absorption circulation effect of the inner liquid cooling layer 13, and gaining effective time for the maintenance personnel's emergency repairs and inspections, thereby effectively reducing economic losses.

[0031] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
