The outer top column sleeve 128 is fixedly installed with a copper nose placement head 132 in a manner that is easy to disassemble. The copper nose placement head 132 is provided with an open groove for placing the copper nose, spring gasket and nut. The copper nose placement head 132 is also equipped with an open groove that matches the curling cylindrical position of the copper nose to locate the position of the copper nose. The main support rod 105 is also surrounded by a top spring 130, which is arranged between the top pipe 131 and the electromagnet 129, wherein the top pipe 131 is used to push out the copper nose, spring gasket and nut on the copper nose placement head 132. The guide slide 109 is slidably matched with the nut locking arm 106, and the nut locking buckle 110 is fixedly matched with the guide slide 109. The nut locking arm 106 is also fixedly installed with an electric cylinder 107, and the telescopic rod end of the electric cylinder 107 is movably connected to the end of the guide slide 109 away from the nut locking buckle 110 through a connecting rod 108. A swing driving motor 113 is also fixedly mounted on the main support rod 105 , a swing driving gear 112 is fixedly mounted on the output shaft of the swing driving motor 113 , and a swing driven gear 111 meshing with the swing driving gear 112 is fixedly mounted on the nut locking arm 106 .

[0023] Four conveying guide studs 123 are rotatably mounted on the conveying guide stud support frame 117. The four conveying guide studs 123 are divided into two groups on the left and the right. The two conveying guide studs 123 on the left and the two conveying guide studs 123 on the right are symmetrically arranged. The two conveying guide studs 123 on the left and the right rotate synchronously through a synchronous transmission belt 122, and the two symmetrically arranged conveying guide studs 123 at the bottom are meshed and transmitted through two interlocking gears 121; a gearbox 116 is fixedly mounted on the bottom support plate 114, and the output shaft of the gearbox 116 is fixed to one of the interlocking gears 121. A cable reel 124 is rotatably mounted on the bottom support plate 114, and the cable reel 124 is connected to the input shaft of the gearbox 116 via a power transmission belt 125. A spring power storage box body 115 is provided at the rotation connection between the cable reel 124 and the bottom support plate 114, and is used to reset the cable reel 124 to rotate in the opposite direction. The spring power storage box body 115 consists of an outer shell and a spring, wherein the outer shell is fixed to the bottom support plate 114, the outer ring of the spring is fixed to the outer shell, and the inner ring of the spring is fixed to the cable reel 124 via a rotating shaft.

[0024] Below the two symmetrically arranged transmission guide studs 123 at the bottom, a rubber cone guide cover bracket 126 fixed on the transmission guide stud support frame 117 is provided, and an open through hole is provided on the rubber cone guide cover bracket 126, and a rubber cone guide cover 127 is fixedly provided at the open through hole, and an open groove is provided on the rubber cone guide cover 127 for releasing the optical fiber. The pull-up 103 is wound around the winding drum 124, and a pull ring 104 is provided at one end of the pull-up 103. The inner wall sliding seal of the heat-conducting silicone injection cylinder 118 is matched with a push piston 119, and an air pump 120 is installed at the open end of the heat-conducting silicone injection cylinder 118. The air pump 120 is used to increase the pressure in the heat-conducting silicone injection cylinder 118, and push the heat-conducting silicone to flow into the heat-conducting silicone injection tube 133 by pushing the piston 119.

[0025] According to the specific construction scene, select an extension rod 101 of appropriate length and install it at the end of the main support rod 105. Place the copper nose, spring gasket and nut in the open groove of the copper nose placement head 132 (the electromagnet 129 needs to be started first, and the electromagnet 129 will attract the top pipe 131 when it is energized, and the top pipe 131 will come out of the open groove of the copper nose placement head 132, and the top spring 130 is in a compressed state), then start the air pump 120, the air pump 120 will increase the pressure in the thermal conductive silicone injection cylinder 118, and the pressure will push the piston 119 to slide on the inner wall of the thermal conductive silicone injection cylinder 118, thereby squeezing the thermal conductive silicone inside the thermal conductive silicone injection cylinder 118, and flowing into the thermal conductive silicone injection tube 133, at this time, the thermal conductive silicone will be squeezed into the copper nose through the thermal conductive silicone injection tube 133, and then stop the air pump 120. When the electromagnetic coil inside the nut locking arm 106 is energized, the electromagnetic coil generates a magnetic field that attracts or repels the external top column sleeve 128 (because there is a permanent magnet inside the external top column sleeve 128), which is now in an attractive state. The external top column sleeve 128 will move toward the stud away from the temperature measurement point to be installed, and then the electromagnet 129 is powered off. At this time, the top tube 131 loses the attraction of the electromagnet 129, and the copper nose, spring washer and nut are squeezed under the action of the top spring 130, so that the copper nose, spring washer and nut move toward the stud at the temperature measurement point. Since the external top column sleeve 128 drives the copper nose placement head 132 to separate from the copper nose, spring gasket and nut, there is no shielding around the copper nose, spring gasket and nut at this time, and then the telescopic rod of the electric cylinder 107 is controlled to retract, and the telescopic rod of the electric cylinder 107 drives the guide slide bar 109 to slide on the nut locking arm 106 through the connecting rod 108, and the guide slide bar 109 drives the nut locking buckle 110 to move toward the nut, so that the nut locking buckle 110 clamps the nut (due to the effect of the open groove on the copper nose placement head 132, the placement orientation of the nut is determined), and then the output shaft of the swing drive motor 113 is controlled to rotate, and the output shaft of the swing drive motor 113 drives the swing driving gear 112 to rotate, and the swing driving gear 112 drives the swinging driven gear 111 to rotate, and the swinging driven gear 111 drives the nut locking arm 106 to rotate on the main support rod 105. When the nut locking arm 106 swings to an extreme position (it cannot rotate in one direction all the time due to blocking interference), the nut locking arm 106 is controlled to swing in the opposite direction by the swing driving motor 113, and at the same time, the telescopic rod of the electric cylinder 107 is controlled to extend, so that the nut locking buckle 110 is separated from the nut. Then, when the nut locking arm 106 swings to another extreme position, the above steps are repeated to tighten the nut and the stud. At the same time, the copper nose and the spring gasket will be fixed on the stud, and under the restriction of the anti-rotation guide slide rod 134, the curled cylindrical position of the copper nose is always facing downward.Then pull the pull ring 104, the pull ring 104 drives the pull 103, the pull 103 drives the winding drum 124 to rotate, the winding drum 124 drives the clockwork storage box 115 to store power, and at the same time drives the input shaft of the gearbox 116 to rotate through the power transmission belt 125, and the output shaft of the gearbox 116 will drive the linkage gear 121 to rotate, and the rotation of the linkage gear 121 will drive another linkage gear 121 to rotate, and then the four transmission guide studs 123 are rotated at the same time through two synchronous transmission belts 122. Since the transmission guide stud 123 is provided with a spiral groove, and the two symmetrically arranged spiral grooves are aligned, the purpose of transmitting the optical fiber can be achieved. It should be noted that, at the beginning, the temperature measuring end of the optical fiber needs to be inserted into the rubber conical guide cover 127, and then the pull ring 104 is slightly pulled to rotate the transmission guide stud 123 so that the temperature measuring end of the optical fiber enters the spiral groove of the transmission guide stud 123. Therefore, when the spiral groove of the transmission guide stud 123 rotates, the temperature measuring end of the optical fiber will be driven to move along the axial direction of the transmission guide stud 123, and at the same time, it will move upward under the action of friction. In order to ensure that the optical fiber temperature measuring end is not damaged, it is necessary to set a rubber protective coating on the surface of the transmission guide stud 123, which can not only protect the optical fiber temperature measuring end but also increase the friction transmission force with the optical fiber. As the optical fiber temperature measuring end moves upward, the optical fiber temperature measuring end will be inserted into the copper nose coated with thermal conductive silicone (using a rolling belt to tie the temperature measuring point and the optical fiber together, an automatic rolling belt machine can be used according to the specific position, or a tape binding method can be used). At this time, the pull ring 104 is continued to be pulled to make the transmission guide stud 123 continue to rotate, and then the optical fiber will be separated from all the transmission guide studs 123, and the entire device can be removed at this time. In this process, the optical fiber will slide out of the open groove of the rubber cone guide cover 127 (as well as the open through hole on the rubber cone guide cover bracket 126, and the rubber cone guide cover 127 is made of soft material). When the pull ring 104 is released, the spring power storage box 115 will drive the winding drum 124 to rotate, and then all the transmission guide studs 123 will return to the initial position, so as to facilitate the insertion of the next optical fiber temperature measurement end.
