Abstract

The present invention relates to a cable protection tube structure with a self-checking function applied to the field of cable protection technology. The structure comprises a protection tube body and a pair of sealing rings. A heat-driven self-checking mechanism is arranged on the protection tube body. The heat-driven self-checking mechanism can automatically check the protection tube body. When the protection tube body is found to be damaged, a reminder is sent to relevant technical personnel through a reminder device, so that the relevant technical personnel not only do not need to actively check the protection tube, but also can find the damage of the protection tube more timely, so that the protection tube can be processed accordingly more timely, thereby enhancing the protection function of the protection tube structure and improving the safety of the cable.

[0003] In order to enhance the protection function of cable protection tubes, many cable protection tubes are sealed and connected to cables. During the use of cable protection tubes, the protection tubes will not only be corroded by environmental factors for a long time, but also be damaged by external forces, which can easily lead to damage of the protection tubes. Once the protection tubes are damaged, their protection function for the cables will be significantly reduced, which needs to be discovered and handled in time.

[0009] As a further improvement of the present application, a pair of restoring elastic ropes are fixedly connected to the bottom end of the sealing slide, and the other ends of the restoring elastic ropes are fixedly connected to the heat conducting rod, so that the sealing slide can automatically reset after the air pressure inside the protective tube body returns to normal.

DETAILED DESCRIPTION

[0028] Three implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0029] The first implementation method:

[0030] Figure 1-4A cable protection tube structure with a self-test function is shown, comprising a protection tube body 101 and a pair of sealing rings 102, wherein the protection tube body 101 is sealedly connected to the cable 004 through the sealing rings 102, and a heat-driven self-test mechanism is arranged on the protection tube body 101, wherein the heat-driven self-test mechanism comprises a self-test support tube 201 which is embedded in the protection tube body 101, wherein the bottom end of the self-test support tube 201 is arranged in an open shape, wherein a fixing plate 202 is fixedly installed in the self-test support tube 201, and a fixing plate 202 which is connected to the self-test support tube is arranged below the fixing plate 202. The sealing plate 201 is movably and hermetically connected, a heat conducting rod 204 is penetrated on the fixed plate 202, the heat conducting rod 204 is fixedly connected to the fixed plate 202, the heat conducting rod 204 penetrates the sealing plate 203 and is movably and hermetically connected thereto, a pressure touch button 205 is fixedly installed at the bottom end of the fixed plate 202, a shape memory driving spring 206 movably connected thereto is sleeved on the heat conducting rod 204, a trigger plate 207 is fixedly connected to the top end of the shape memory driving spring 206, the heat conducting rod 204 penetrates the trigger plate 207 and is The self-test support tube 201 is movably connected, a hot touch button 208 is fixedly installed on the inner wall of the top of the self-test support tube 201, a reminder 209 is fixedly installed on the outer wall of the top of the self-test support tube 201, a self-test microcontroller 003 is fixedly installed in the self-test support tube 201, and a self-test analysis module and a reminder control module are set in the self-test microcontroller 003. The pressure touch button 205 and the hot touch button 208 are both connected to the self-test analysis module signal, the self-test analysis module is connected to the reminder control module signal, and the reminder control module is connected to the reminder 209 Signal connection, the pressure touch button 205 is located above the sealing slide plate 203, the bottom end of the shape-memory drive spring 206 is against the top of the fixed plate 202, the thermal touch button 208 is located above the trigger plate 207, the pressure touch button 205 and the thermal touch button 208 are both self-resetting buttons, the thermal rod 204 is made of heat-conducting material, the shape-memory drive spring 206 is made of shape memory alloy material with two-way memory effect, and the phase change temperature of the shape-memory drive spring 206 is lower than the highest normal working temperature of the cable 004.

[0031] See also Figure 1-5When the cable 004 is working, it will generate a certain amount of heat, causing the temperature inside the protection tube 101 to rise. The heat-conducting rod 204 can guide part of the heat to the shape-memory drive spring 206, causing the temperature of the shape-memory drive spring 206 to rise. When the temperature of the shape-memory drive spring 206 rises to its phase change temperature, it will deform and elongate. The elongation of the shape-memory drive spring 206 will push the trigger plate 207 upward, causing the trigger plate 207 to squeeze and trigger the thermal touch button 208. Under normal circumstances, when the temperature inside the protection tube 101 rises, the air pressure inside it will also increase. If the protection tube 101 is not damaged, before the thermal touch button 208 is triggered, the sealing slide plate 203 will be pushed upwards by the air pressure to squeeze and trigger the pressure touch button 205. However, if the protection tube 101 is damaged, air will leak out from the damaged part, so that the air pressure inside the protection tube 101 will not increase significantly, and the sealing slide plate 203 will not be able to trigger the pressure touch button 205. As a result, when the thermal touch button 208 is triggered, the pressure touch button 205 will be in an untriggered state. Therefore, the self-checking analysis module can analyze the pressure touch button 205, the thermal touch button 208 and the pressure touch button 205. 8, and judge whether the protection tube body 101 is damaged. When the thermal touch button 208 is triggered and the pressure touch button 205 is not triggered, the self-checking analysis module sends a signal to the reminder control module, causing the reminder control module to start the reminder 209, so that the reminder 209 makes a sound to remind the relevant technicians. Therefore, through the setting of the thermal drive self-checking mechanism, the thermal drive self-checking mechanism can automatically detect the protection tube body 101 at irregular intervals. When the detection finds that the protection tube body 101 is damaged, it will notify the relevant technicians through the reminder 209. The reminder is issued so that the relevant technical personnel not only do not need to actively inspect the protective tube, but also can discover the damage of the protective tube more promptly, so that the protective tube can be treated accordingly more promptly, thereby enhancing the protection function of the protective tube structure and improving the safety of cable 004. The thermal drive self-inspection mechanism cleverly uses the heat generated by cable 004 when working to drive the detection, which is not only energy-saving and environmentally friendly, but also greatly reduces the energy consumption of the thermal drive self-inspection mechanism and improves the endurance of the thermal drive self-inspection mechanism, thereby improving the practicability and reliability of the protective tube structure.

[0032] See also Figure 3 A pair of restoring elastic ropes 210 are fixedly connected to the bottom end of the sealing slide plate 203, and the other end of the restoring elastic ropes 210 is fixedly connected to the heat conducting rod 204, so that after the air pressure inside the protection tube body 101 returns to normal, the sealing slide plate 203 can be automatically reset.

[0033] The second implementation method:

[0034] Figure 6-7A cable protection tube structure with a self-test function is shown. Different from the first embodiment, the cable 004 protection tube structure also includes a cooling and heat dissipation mechanism. The self-test microcontroller 003 is also provided with a cooling control module. The cooling and heat dissipation mechanism includes an air pump 501 and an exhaust pipe 502 and an air intake pipe 503 arranged on the protection tube body 101. The exhaust pipe 502 and the air intake pipe 503 are both connected to the interior of the protection tube body 101, and the end of the exhaust pipe 502 away from the protection tube body 101 is connected to the suction end of the air pump 501. An exhaust solenoid valve 504 is provided on the exhaust pipe 502, and an air intake solenoid valve 505 is provided on the air intake pipe 503. The self-test analysis module is signal-connected to the cooling control module. The cooling control module is signal-connected to the air pump 501, the exhaust solenoid valve 504 and the air intake solenoid valve 505. The cooling and heat dissipation mechanism also includes a temperature sensor arranged on the inner side of the protection tube body 101, and the cooling control module is signal-connected to the temperature sensor.

[0035] See also Figure 6-7 After the thermal touch button 208 is triggered, the self-test analysis module will send a signal to the cooling control module. After receiving the signal, the cooling control module will open the exhaust solenoid valve 504, the intake solenoid valve 505 and start the vacuum pump 501. The vacuum pump 501 can extract the hot air with a relatively high temperature inside the protective tube body 101 through the exhaust pipe 502, and the cold air with a relatively low temperature in the environment can enter the inside of the protective tube body 101 through the intake pipe 503, thereby achieving a rapid cooling effect on the cable 004. After receiving the signal, the cooling control module will also start the temperature sensor to monitor the temperature inside the protective tube body 101, and the temperature data monitored by the temperature sensor will be transmitted to the cooling control module in real time. Relevant technicians can pre-set a temperature threshold and input this temperature threshold into the cooling control module. In the embodiment, when the temperature inside the protective tube body 101 drops to the temperature threshold, the cooling control module will close the exhaust solenoid valve 504, the intake solenoid valve 505, the air pump 501, and the temperature sensor. Therefore, through the joint setting of the thermal drive self-inspection mechanism and the cooling and heat dissipation mechanism, the cable 004 protection tube structure in the present application also has an active cooling and heat dissipation function, which can quickly reduce the temperature of the cable 004 when the temperature of the cable 004 is high, thereby improving the functionality of the protection tube structure and further improving the safety of the cable 004. In addition, after the thermal touch button 208 is triggered, the cooling control module will control the cooling and heat dissipation mechanism to cool the inside of the protective tube body 101, so that the temperature sensor does not need to be in the startup state all the time to monitor the temperature inside the protective tube body 101, thereby reducing the energy consumption of the temperature sensor.

[0036] The third implementation method:

[0037] Figure 8-10A cable protection tube structure with a self-checking function is shown. Different from the first and second embodiments, the heat-driven self-checking mechanism also includes a ball-dropping reminder component, which includes a support box 601 embedded in the side wall of the self-checking support tube 201, a magnetic isolation plate 602 movably connected to the support box 601 is penetrated on the top outer wall, a linkage plate 603 movably connected to the support box 601 is penetrated on the bottom outer wall, a driving magnet 604 is fixedly connected to the linkage plate 603 on the side close to the magnetic isolation plate 602, a ball storage tube 605 is embedded in the outer wall of the support box 601 away from the heat-conducting rod 204, a transparent ball receiving tube 606 is embedded in the bottom outer wall of the ball storage tube 605, and a movable iron movably installed in the ball storage tube 605. Plate 607, a reminder ball 608 is arranged just above the transparent ball receiving tube 606, a ball-piercing rod 609 is fixedly connected to the side of the movable iron plate 607 close to the reminder ball 608, the ball-piercing rod 609 penetrates the reminder ball 608 and is movably connected thereto, the magnetic isolation plate 602 is located between the driving magnet 604 and the ball storage tube 605, and the magnetic isolation plate 602 is made of magnetic isolation material, the top of the magnetic isolation plate 602 is fixedly connected to the trigger plate 207, the bottom end of the linkage plate 603 is fixedly connected to the sealing slide plate 203, the transparent ball receiving tube 606 is located outside the self-inspection support tube 201, the transparent ball receiving tube 606 is made of transparent material, and the top of the transparent ball receiving tube 606 is set to an opening shape, and the reminder ball 608 is located on the side of the movable iron plate 607 away from the driving magnet 604.

[0038] See also Figure 8-10When the sealing slide plate 203 is pushed upward by the air pressure, the linkage plate 603 and the driving magnet 604 will move upward together. When the shape memory driving contact spring 206 is deformed and stretched to push the trigger plate 207 upward, the magnetic isolation plate 602 will move upward together with the trigger plate 207. Therefore, under normal circumstances, the magnetic isolation plate 602 will always be between the driving magnet 604 and the trigger plate 207. However, if the protection tube 101 is damaged, when the shape memory driving contact spring 206 is deformed and stretched, the magnetic isolation plate 602 will move upward together with the trigger plate 207. 6 deforms and stretches, so that the trigger plate 207 and the magnetic isolation plate 602 move upward, because the sealing slide plate 203 is not pushed upward, the driving magnet 604 will remain motionless. In this case, the magnetic isolation plate 602 will be staggered with the driving magnet 604, causing the movable iron plate 607 to move away from the reminder ball 608 under the action of the magnetic attraction of the driving magnet 604. The movement of the movable iron plate 607 will drive the ball-piercing rod 609 to move together, causing the ball-piercing rod 609 to The reminder ball 608 is detached, and then the reminder ball 608 falls into the transparent ball receiving tube 606. Therefore, if the reminder 209 fails to effectively remind the relevant technicians due to the exhaustion of power or failure of the reminder 209, the relevant technicians can also be reminded by observing that the ball rod 609 falls into the transparent ball receiving tube 606, and then find that the protective tube body 101 is damaged. Therefore, through the setting of the falling ball reminder component, the falling ball reminder component can also serve as a reminder. Even if the reminder 209 fails to effectively remind the relevant technicians for some reasons, the relevant technicians do not need to actively inspect the protective tube, and the falling ball reminder component can also enable the relevant technicians to discover the damage of the protective tube more promptly to a certain extent, thereby improving the practicality and reliability of the thermal drive self-inspection mechanism, and further enhancing the protection function of the protective tube structure, and further improving the safety of the cable 004.

[0039] See also Fig.10 A support rod 610 is fixedly installed in the ball storage tube 605, and the support rod 610 can support and guide the movable iron plate 607. The support box 601 passes through the movable iron plate 607 and is movably connected thereto. A pair of ball-locking rods 611 are fixedly connected to the bottom end of the support box 601. The pair of ball-locking rods 611 are respectively located on the left and right sides of the reminder ball 608. The ball-locking rods 611 can prevent the reminder ball 608 from moving with the movable iron plate 607 and the ball-piercing rod 609, which is conducive to the separation of the reminder ball 608 and the ball-piercing rod 609.

[0040] See also Fig.10An elastic pull rope 612 is fixedly connected between the movable iron plate 607 and one of the ball-locking rods 611, and the elastic pull rope 612 can prevent the movable iron plate 607 from accidentally sliding. The outer surface of the reminder ball 608 is painted with a reflective coating to improve the reminder effect of the reminder ball 608. The end of the ball storage tube 605 away from the magnetic isolation plate 602 is set to an open shape and is provided with a tube cover 613. The transparent ball receiving tube 606 is threadedly connected to the outer wall of the bottom end of the ball storage tube 605, so that after the reminder ball 608 falls into the transparent ball receiving tube 606, it is easy to put it back on the reminder ball 608, so that the dropped ball reminder component can be reused, which improves the practicality of the dropped ball reminder component.

[0041] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
