Description

A FIBRE-TO-THE-HOME JETTING DEVICE
The subject matter of this invention is a FTTH jetting device. The name "Fibre to the Home" is used to mean the last sections of the optical fibre connection, which are ended in the subscriber's home. Those cables are from several dozen to several hundred metres long and from 0.8 to 3 mm in diameter. They are introduced into ducts, most often 7 or 10 mm in diameter, and run from distribution junction boxes to the various buildings/premises. There are from a few to several dozen tubes spreading out from one distribution box.
The devices currently used for jetting that fibre optic cable category as a rule operate on the basis of cable blowing-in and pushing at the same time. For that purpose, those devices are equipped with an openable, and then tightly closable blowing-in and pushing chamber, in which the duct end with a small fibre optic cable section introduced into it on a preliminary basis are placed when the chamber is open.
The cable is jetted into the duct by means of compressed air pressed into the closed chamber, with the simultaneous use of the drive wheel located inside the chamber. The wheel is coupled (e.g. via a magnetic coupling) with an electric or pneumatic motor and, while turning, through contact with the fibre optic cable, causes its pushing into the duct.
The blowing-in and pushing chamber may be adjusted for handling cables and ducts of varying diameters (within the range in their category) through the use of seals corresponding to those diameters; the seals are placed in sockets designated for the purpose inside the chamber, however, only one fibre optic cable and duct set may be handled during a specified time interval.
At present, FTTH service connections are made one by one in such a way that each of the fibre optic cable is blown-in separately. The relevant installation practice indicates that in view of the small diameter of fibre optic cables and, consequently, of the ducts, the demand for blowing-in compressed air is very small. Most frequently, compressors used by contractors for the construction of the systems (in view of the number and "calibre" of uses) have the capacity several times greater than needed for blowing-in one cable. That means that most of blowing-in air supplied by the compressor is unproductively removed into the atmosphere.
At present, air blowing-in takes place in such a way that, at the end of the duct located on the target premises, the operator installs a special tip passing air through, but stopping the fibre optic cable and then he cuts off the cable at some distance before entry into the device (in order to leave some excess length), resets the device for the next tube and repeats the entire process.
The FTTH jetting device in line with the invention consists of the blowing-in and pushing chamber, its drive with equipment and an electronic control system. All those sub-assemblies are integrated with one another in a common enclosure.
The blowing-in and pushing chamber is openable and consists of a chamber body along with a chamber cover connected with the body by means of hinges. The chamber can be tightly closed with closing screws.
The chamber body has at least two tracks for the placing in each of them of a single set consisting of a duct of a varying diameter within a certain range, and of a fibre optic cable corresponding to that diameter. The track has the form of a semi-cylindrical groove at which, in appropriate places, there are sockets for the fibre optic cable seal, for the duct seal, and for the sleeve clamping the duct and fixing it in the chamber body.
Under each of the tracks, there is cable drive wheel with a semi-circular groove on the circumference, suitable for a certain cable diameter range. All the wheels, their number corresponding to the number of tracks, have separate bearings permanently fitted on a common, non-sliding separating sleeve, which is coaxial with the sliding drive shaft. The separating sleeve separates the wheels from the shaft with which they are magnetically coupled by means of drive magnets located on the shaft and bound with reception magnet wheels. Inside the body, next to each wheel on one side, installed is a drive wheel motion sensor, and on the underside installed is a drive wheel blocking mechanism. A blowing-in air connection is installed on the chamber body as well.
The movement of the sliding drive shaft along the longitudinal axis permits the regulation of the value of the torque transferred by the magnetic couplings. The shaft travel is achieved by means of the knob controlling the drive shaft travel mechanism.
The underside of the chamber cover features the grooves matching those in the chamber body (as is the case with one half of the mould and the other identical one) and, above the grooves, the rollers pressing the cables against drive wheels. On the chamber top, there is a roller pressure adjustment screw and a pressure measurement connection.
Following chamber body charging with the sets of ducts with seals and fibre optic cables with seals, upon closing the chamber cover by means of closing screw tightening, a sealed space is created inside the blowing-in and pushing chamber which is prepared for pressing blowing-in air and for cable pushing.
The sliding drive shaft mounted on the sliding shaft bearing assembly and extended out of the blowing-in and pushing chamber on one side, is connected with the drive in the form of the electric motor via toothed belt transmission gear equipped with a drive shaft slide mechanism with a knob.
The electronic control system includes a PLC (programmable logic controller), cable drive wheel motion sensors, a pushing speed potentiometer, on/off control push buttons, a cable length meter display and motor regulator.
The PLC is directly connected by means of a signal course with the cable drive wheel rotation sensors, the cable length meter display and cable drive wheel blocking mechanisms. The motor regulator controls the electric motor independently of the PLC.
The solution in line with the invention permits the simultaneous jetting of several fibre optic cables on several tracks (which substantially reduces the time of the operation), ensures the transfer of the same adjustable torque on all drive wheels thus making the pushing safe and, free from concern about damage of the same kind to the optical fibre, and also offers the opportunity of jetting the sections of various length with the operation continuity being ensured despite stopping the consecutive cables.
The subject matter of the invention is explained in a greater detail on the sample construction shown in the drawings, where Fig. 1 shows the isometric view of the layout in the enclosure of the sub-assemblies of the device equipped with a five-track blowing-in and pushing chamber, which is open and charged. Fig. 2 is the isolated isometric view of an open, charged five-track blowing-in and pushing chamber, partly showing the body inside, and Fig. 3 presents the sectional view of the coupling between the sliding drive shaft and fibre optic cable drive wheels.
The optic fibre cable jetting device in line with the invention consists of the blowing-in and pushing chamber, its drive with equipment and an electronic control system. All those sub-assemblies are integrated with one another in a common enclosure.
The blowing-in and pushing chamber is openable and consists of a chamber body (3) along with a chamber cover (13) connected with the body by means of hinges. The chamber can be tightly closed with closing screws (25)..
The chamber body (3) has at least two tracks for the placing in each of them of a single set consisting of a duct (2) of a varying diameter within a certain range, and of a fibre optic cable (1) corresponding to that diameter. The track has the form of a semi-cylindrical groove at which, in appropriate places, there are sockets (21) for the cable seal, for the duct seal (22), and for the sleeve (23) clamping the duct and fixing it in the chamber body..
Under each of the tracks, there is cable drive wheel (8) with a semi-circular groove on the circumference, suitable for a certain cable diameter range. All the wheels, their number corresponding to the number of tracks, have separate bearings permanently fitted on a common, non-sliding separating sleeve (27), which is coaxial with the sliding drive shaft (9). The separating sleeve separates the wheels from the shaft with which they are magnetically coupled by means of drive magnets (10) located on the shaft and bound with reception magnet wheels (11). Inside the body, next to each wheel on one side, installed is a drive wheel motion sensor (12), and on the underside installed is a drive wheel blocking mechanism (16). A blowing-in air connection (26) is installed on the chamber body as well.
The movement of the sliding drive shaft (9) along the longitudinal axis permits the regulation of the value of the torque transferred by the magnetic couplings. Shaft travel is achieved by means of the drive shaft slide mechanism knob (20) controlling the drive shaft slide mechanism (24).
The underside of the chamber cover (13) features the grooves matching those in the chamber body (3) (as is the case with one half of the mould and the other identical one) and, above the grooves, the rollers pressing the cables against drive wheels. On the chamber top, there is a roller pressure adjustment screw (19) and a pressure measurement connection (17).
Following chamber body (3) charging with the sets of ducts with seals and fibre optic cables with seals, upon closing the chamber cover (13) by means of closing screw (25) tightening, a sealed space is created inside the blowing-in and pushing chamber which is prepared for pressing blowing-in air and for cable pushing.
The sliding drive shaft (9) mounted on the sliding shaft bearing assembly (28) and extended out of the blowing-in and pushing chamber on one side, is connected with the drive in the form of the electric motor (5) via toothed belt transmission gear (7) equipped with a drive shaft slide mechanism (24) with a knob (20).
The electronic control system includes a PLC (programmable logic controller) (6), cable drive wheel motion sensors (12), a pushing speed potentiometer (14), on/off control push buttons (15), a cable length meter display (18) and a motor regulator (4). The PLC (6) is directly connected by means of a signal course with the cable drive wheel rotation sensors (12), the cable length meter display (18) and cable drive wheel blocking mechanisms (16)
The motor regulator (4) controls the motor independently of the PLC (6).
Information on the operation of the device in line with the invention is presented below:
Following the charging of the blowing-in and pushing chamber with the sets of fibre optic cables and ducts with appropriate seals, the operator sets, by means of the drive shaft slide mechanism (24), the torque/cable pushing force transferred by the cable drive wheels (8) and, depending on the cable diameter, adjusts the position of a cable pressure roller against the drive wheels by means of the pressure adjustment screw (19), and then, by pressing the "on" push button, causes the start of the cable pushing process. That push button is connected with the motor regulator (4), which supplies the electric motor (5) with such a value of current voltage and frequency that the motor achieves the speed set on the pushing speed potentiometer (14). During device operation, the PLC (6) reads the revolution numbers from the various drive wheel movement sensors and calculates, on that basis, the length of the blown- in/pushed cable, and displays that value separately for each of the drive wheels on the cable length meter display (18). If any of the wheels is stopped, the PLC receives information on the lack of that wheel rotation and sends an instruction to block that wheel to the drive wheel blocking mechanism (16). This is aimed at stopping the redundant and sometimes destructive pressure on the cable which has reached its destination or encountered an obstacle.
When all the tracks available on the device in line with the invention are in use, the sealing suitable for the cable and tube diameter is installed at a given track; if the demand is reduced, blanking seals are installed at the tracks which are not in operation. Fibre optical cables being jetted have various lengths and when one of them is stopped, the given drive wheel is subject to lost motion on the magnetic coupling.
The cable jetting operation continues until the stop of the last, longest section. Explanations of drawing markings - Fibre optic cable
