Description

Technical Field

[0001] The invention relates to the technical field of optical fiber air blowing equipment, and in particular to an air blowing device and an application method thereof that facilitates rapid blowing of optical fibers into microtubes. Background Art

[0002] The optical fiber air blowing machine is a device specially used for the construction and maintenance of optical fiber communication networks. It mainly uses high-pressure gas to blow optical fibers into pre-laid pipes. This equipment plays an important role in the construction of optical fiber networks. The air blowing chamber of the existing equipment is not sealed enough. The optical fiber is in the air blowing process, and the air blowing speed is slow, which makes it impossible to blow micro-tubes with longer lengths. At the same time, when the micro-tubes are bent, connected, or there are impurities in the micro-tubes during air blowing, the optical fiber will not be able to pass through the micro-tubes, resulting in air blowing interruption. In addition, in the case of no power supply outdoors, the number of existing aluminum batteries is limited, which cannot meet the long-term operation of the equipment. As a result, when the air blowing work is halfway through, the equipment needs to be charged to continue the air blowing work, which increases the time of the air blowing work and reduces the work efficiency. Therefore, a high-speed wrapping device for motor lead wires and an application method thereof are proposed. Summary of the invention

[0013] The present invention also proposes an application method of the wrapping device, and the application method is as follows: a. Install the optical fiber in the channel of the optical fiber support device, then pass it between the driving wheel and the driven wheel, and enter the air blowing chamber; b. When the optical fiber passes through one end of the air blowing chamber, the optical fiber is first passed through the sealing ring set on the channel to form the first seal, and then the optical fiber is passed through the optical fiber support ring on the channel to form the second seal. When the microtube passes through the other end of the air blowing chamber, the microtube needs to be passed through the sealing ring on the channel to form the third seal. The sealing ring connects the two sealing rings together to form the fourth seal; and the optical fiber that passes through the optical fiber support ring needs to be installed with a hollow guide head at the end of the optical fiber, and the optical fiber with the hollow guide head installed is passed through the air blowing hole and then passed into the microtube; c. Start the power supply of the equipment, so that the driving motor drives the active wheel, and the active wheel drives the driven wheel to rotate.

The conical surface on the hollow guide head can increase the strength of the optical fiber and guide the optical fiber to pass through the microtube bend or microtube joint, avoiding the optical fiber being blocked at the microtube bend or stuck in the seam of the microtube joint due to being too thin, interrupting the optical fiber penetration, so that the optical fiber can smoothly pass through the microtube with a longer length. At the same time, the gas can pass through the hollow cavity to blow impurities and dust in the microtube out of the microtube, increasing the conductivity of the microtube, so that the equipment is suitable for use in complex scenes such as long length and microtube bending. At the same time, the hollow guide head is easy to disassemble and assemble and can be reused; The USB interface allows construction workers to charge battery packs or other electrical devices by connecting to the USC interface during operation, increasing the practicality of the equipment.

Embodiment 1

[0028] First, connect the air pump to the air inlet on the air control valve 4 through the air pipe; Then use a screwdriver to remove the fixing screws on the optical fiber support device 9 and the air blowing chamber 3, and open the optical fiber support device 9 and the air blowing chamber 3; Then install the optical fiber on the optical fiber support device 9, close the optical fiber support device 9, and lock the optical fiber support device 9 with screws. The optical fiber needs to be placed in the channel 34 on the optical fiber support device 9 to prevent the optical fiber support device 9 from pressing the optical fiber and causing the optical fiber to be broken; Then the optical fiber is passed between the driving wheel 22 and the driven wheel 23 of the traction mechanism 2; Next, the optical fiber is inserted into the channel 34 on one end of the air blowing bin 3, and the microtube is inserted into the channel 34 on the other end of the air blowing bin 3. The optical fiber passing through the air blowing bin 3 must first pass through the sealing ring 35 on the channel 34 to form the first seal on the air blowing bin 3 with the optical fiber and the channel 34, and then pass through the optical fiber support ring 38 on the channel 34. One end of the optical fiber support ring 38 is made of rubber material and has a sealing effect, so that it forms the second seal on the air blowing bin 3 with the optical fiber and the channel 34. Then, one end of the optical fiber is installed on the hollow guide head 8 and passes through the air blowing hole 36 and the microtube inserted into the channel 34. The microtube entering the other end of the air blowing bin 3 needs to pass through the sealing ring 35 on the channel 34 to seal it with the optical fiber and the channel 34. The microtube and the channel 34 form the third seal on the air blowing bin 3. The first, second and third seals are set to prevent the optical fiber and microtube entering the channel 34 from leaking after entering, which affects the air blowing force. At the same time, a sealing ring 37 is added around the air blowing hole 36, and the sealing ring 37 connects the two sealing rings 35 on the channel 34. Under the action of the locking member 33, the upper bin body 31 and the lower bin body 32 are pressed tightly to form a fourth seal, thereby increasing the sealing of the air blowing bin 3; the air blocking groove on the air blowing hole 36 blocks the gas entering the air blowing hole 36 to prevent the gas from going out from the fiber inlet end, so that the gas blows the optical fiber gas into the microtube from the fiber outlet end along the air guide groove on the air blowing hole 36, thereby increasing the air blowing force.

[0029] Then turn on the power switch 7 on the chassis 1 to start the equipment. The power converter 10 converts the connected power supply into a DC voltage of 12V and drives the drive motor 21 to rotate, which drives the active wheel 22 to rotate, and the active wheel 22 drives the driven wheel 23 to rotate, so that the meter 29 set on the driven wheel 23 starts to measure the optical fiber traction length. The meter 29 is electrically connected to the encoder to transmit the optical fiber air-blown length to the encoder, and the air-blowing speed is obtained by conversion, which is displayed on the display 6 for the construction personnel to read.

[0030] If a fault occurs during the construction process; the meter 29 stops working, the encoder receives a signal, the drive motor 21 stops running, the motor reader reads the working signal of the drive motor 21 to stop, the encoder drives the buzzer 11 to sound an alarm, the air blowing device stops running, and the power switch 7 is started again after the fault is eliminated; After the construction is completed or the equipment is maintained, turn off the power switch 7 and disconnect the power supply. Embodiment 2

[0031] When the use environment is different, switch the power supply mode by switching the switch 15, the power supply mode is 220V mains and battery pack 14; When there is a power source available, the switching switch 15 is switched to the 220V AC power supply mode, so that the circuit in the device is connected to the 220V AC power socket 13; and the power plug is connected to the 220V AC power socket 13 on the chassis 1, and the power plug needs to be connected to the 220V AC power or the generator, connecting the power supply modes of the 220V AC and the generator, and the adjustment of the switching switch 15 is consistent.

[0032] When there is no power supply outdoors, the switch 15 is switched to the power supply mode of the battery pack 14, so that the circuit in the device is connected to the battery pack 14; and the battery pack 14 is inserted into the battery holder. When the battery pack 14 is out of power, the battery pack 14 can be replaced to store power for the air blowing device, thereby extending the power usage time of the device; The USB interface 12 can discharge electricity externally to charge the battery pack 14 or other electrical devices.

[0033] The protection scope of the present invention is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present invention.

10. The method for applying the air blowing device according to any one of claims 1 to 9, characterized in that: The application method is as follows: a. Install the optical fiber in the channel of the optical fiber support device, then pass it between the driving wheel and the driven wheel, and enter the air blowing chamber; b. When the optical fiber passes through one end of the air blowing chamber, the optical fiber is first passed through the sealing ring set on the channel to form the first seal, and then the optical fiber is passed through the optical fiber support ring on the channel to form the second seal. When the microtube passes through the other end of the air blowing chamber, the microtube needs to be passed through the sealing ring on the channel to form the third seal. The sealing ring connects the two sealing rings together to form the fourth seal; and the optical fiber that passes through the optical fiber support ring needs to be installed with a hollow guide head at the end of the optical fiber, and the optical fiber with the hollow guide head installed is passed through the air blowing hole and then passed into the microtube; c. Start the power supply of the equipment, so that the driving motor drives the active wheel, and the active wheel drives the driven wheel to rotate. The friction between the active wheel and the driven wheel pulls the optical fiber into the air blowing chamber, and the gas blows the optical fiber into the microtube at the other end of the air blowing chamber.
