DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] First embodiment:

[0024] See also Figure 1-Figure 4 The present invention provides a fiber optic cable down-lead steel pipe drainage device 17 with an inflation function: it is composed of a main box 1, an inlet pipe 2 and a front cover 3, the right end of the main box 1 is connected to the inlet pipe 2 by buckling, the front cover 3 is arranged at the front end of the main box 1 and buckled with the main box 1, the rear end of the main box 1 is provided with a fixing frame device 6 and locked with the rear end of the main box 1, a connecting sleeve 5 is provided below the fixing frame device 6, and a protective steel pipe 4 is buckled below the connecting sleeve 5;

[0025] The fixing frame device 6 is composed of a slider 7, a fixed guide rail 8, a first clamping plate 9, an inner sleeve 10, an outer sleeve 11, a contact pad 12 and a second clamping plate 13. The fixed guide rail 8 is installed on the main box 1, and the slider 7 is slidably installed on the fixed guide rail 8. One end of the first clamping plate 9 is buckled with the fixed guide rail 8 through the slider 7. The inner sleeve 10 is provided at the other end of the first clamping plate 9 and buckled with the first clamping plate 9. An outer sleeve 11 is provided on the right side of the inner sleeve 10. The outer sleeve 11 and the inner sleeve 10 are loosely matched. A second clamping plate 13 is provided on the inner side of the outer sleeve 11. The end of the second clamping plate 13 away from the outer sleeve 11 is buckled with the fixed guide rail 8 through the slider 7. The inner side of the first clamping plate 9 and the inner side of the second clamping plate 13 are buckled with a contact pad 12.

[0026] The contact pad 12 is composed of a fitting inner pad 14, a tight groove block 15 and an anti-slip strip 16. The fitting inner pad 14 is buckled with the anti-slip strip 16. The tight groove block 15 is arranged in the middle of the anti-slip strip 16 and is buckled with the anti-slip strip 16. The contact pad 12 can form a relatively tight fixed fit with the overhead layer of the electric pole through the cooperation between the tight groove block 15 and the anti-slip strip 16.

[0027] The main feature of the present invention is: by placing the equipment at a suitable height, with the cooperation of the fixed guide rail 8 and the slider 7, the first clamping plate 9 and the second clamping plate 13 on both sides are close to each other, and the fitting inner pad 14 mainly plays a connecting role. Through the internal tight groove block 15 and the anti-slip strip 16, a relatively tight fit can be formed with the outer wall of the pole, and then the inner sleeve 10 and the outer sleeve 11 are nested and locked with each other, at this time, the main box 1 is fixed, and by burying the bottom end of the protective steel pipe 4 into the soil to a certain depth, the upper end of the optical cable enters the main box 1 along the incoming pipe 2 and forms a transmission line with the protective steel pipe 4, thereby protecting the optical cable, and the main box 1 can also play an anti-freezing and water drainage effect on the inside of the protective steel pipe 4.

[0028] Second embodiment:

[0029] See also Figure 4-Figure 5 The present invention provides a fiber optic cable down-lead steel pipe drainage device with an inflation function: the main box 1 is composed of a drainage device 17, an outer frame 18, a control unit 19, a transition pipe 20 and a power distribution compartment 21, the control unit 19 is arranged on the upper part of the outer frame 18, the drainage device 17 is connected to the middle of the outer frame 18 by locking, the power distribution compartment 21 is arranged on the rear side of the drainage device 17, and the transition pipe 20 is installed on the right side of the drainage device 17.

[0030] The drainage device 17 is composed of an inflation groove 22, an electrical connection groove 23, an auxiliary hot air blower 24 and a diverter sleeve device 25. The auxiliary hot air blower 24 is installed on the diverter sleeve device 25, and the diverter sleeve device 25 is buckled with the auxiliary hot air blower 24. The electrical connection groove 23 is installed above the auxiliary hot air blower 24 and is buckled with the auxiliary hot air blower 24. The inflation groove 22 is locked to the side of the auxiliary hot air blower 24. The diverter sleeve device 25 is composed of a main flow groove 26, an isolation cover 27, an outer tube body 29, and a diverter pipe. The middle part of the isolation cover 27 is penetrated by the main flow groove 26, and a diverter pipe is buckled below the main flow groove 26 and is located on the inner side of the outer tube body 29. A wiring groove 28 is provided on the side of the outer tube body 29. The diverter sleeve device 25 transfers the warm air flow to the lower diverter pipe through the main flow groove 26, and forms an auxiliary effect of inflation and heating for protecting the internal tube gap of the steel pipe 4.

[0031] The main feature of the present invention is that the optical cable enters the transition pipe 20 along the incoming pipe 2, and enters the outer tube body 29 along the wiring groove 28, and then is transmitted along the connecting sleeve 5 and the protective steel pipe 4. The control unit 19 can receive commands remotely. When the sensor unit provided at the bottom of the protective steel pipe 4 gives an early warning, the auxiliary heating fan 24 will be triggered to start, and the power distribution bin 21 and the power connection groove 23 will provide power distribution support. Air is drawn in through the inflation groove 22 and converted into warm air for output with the cooperation of the auxiliary heating fan 24. The airflow is gradually transmitted to the diversion pipe along the main flow groove 26 in the middle of the isolation cover 27. At this time, the warm air will be transmitted to the gap inside the protective steel pipe 4, thereby heating the humid and cold space inside it to protect the optical cable from being frozen.

[0032] The present invention combines the above-mentioned components with each other, so that when the device is used, the device can prevent the overhead optical cable from being introduced into the underground ditch from the overhead pole tower through the provided mechanism. The optical cable protection steel pipe 4 needs to be installed at the part where the optical cable enters the ground, and the steel pipe is partially buried underground and partially fixed on the optical cable overhead pole tower; rainwater or snowmelt water can easily flow into the steel pipe through the upper opening, or penetrate into the steel pipe through the lower opening. Once the water enters the steel pipe, it is very difficult to evaporate or penetrate into other places. When the weather turns cold, once the water inside freezes, it will cause the optical cable to be frozen and broken. The rack device 6 can effectively fix the equipment tightly on the electric pole. The optical cable is arranged along the inlet pipe 2 and downward along the transition pipe 20. The angle of the inlet pipe 2 avoids the traditional vertical protection of the steel pipe 4, reducing water ingress. At the same time, the drainage device 17 can detect the temperature inside the steel pipe through an externally arranged pipeline temperature sensor. When the warning temperature is reached, it automatically starts to transport heating to the internal gap of the protective steel pipe 4, thereby avoiding groundwater infiltration and internal water accumulation, and effectively protecting the stable and safe use of the optical cable.
