Definitions

  • the present invention relates to improved electrodes With cathodic protection, especially to ferro-silicon electrodes which may be readily connected with the feed wires, and to a novel method of connecting the electrodes in accordance with the present invention to the feed wires.
  • the present invention relates to an electrode which may, if so desired, be readily realized of cast-iron containing silicon, of which the cost of production is less than that of the electrodes known heretofore and of which the assembly, itself rapid and easy, which takes place without cutting the cable into sections, may be effected without any difiiculty on the job. It is also understood, of course, that the present invention is independent of the particular material constituting the electrode.
  • the electrode according to the present invention is particularly characterized by the fact that it is provided with a bore of which at least a portion is conical.
  • the securing of the electrode to the cable and its connection with the latter are assured by the wedging action within the conical portion of the central bore of the electrode of one or several conical elements which traverse the cable axially or which surround the same.
  • a further object of the present invention resides in the provision of electrodes particularly made of ferro-silicon alloys, to which a desired shape is given by casting in such a manner as to obviate the need for further machining.
  • Still another object of the present invention is the provision of electrodes made of hard alloys difficult to machine, which may be readily connected to the feed cable without requiring cutting of the feed cable and which in no way impairs the electrical connection nor the mechanical support function of the cable.
  • Still a further object of the present invention resides in the provision of novel, improved ferro-silicon electrodes and to a method of mounting and electrically connecting the same to the cable which is simple, relatively inexpensive in assembly and which permits the electrode assembly to be immersed in liquid without danger of corrosion to the conection.
  • FIGURE 1 is a longitudinal cross sectional view through an electrode in accordance with the present invention mounted on a cable
  • FIGURE 2 is a longitudinal cross sectional view through the electrode of FIGURE 1, illustrating the assembly thereof,
  • FIGURE 3 is an axial longitudinal cross sectional view through one of the two half-shells or casings assuring the electrical connection between the cable and the electrode,
  • FIGURE 4 is a device which may be utilized for the assembly in accordance with the present invention.
  • FIGURE 5 illustrates schematically a plurality of electrodes according to the present invention mounted along a cable and immersed for the protection of an immersed construction.
  • the electrode 1 illustrated therein is made of cast-iron containing silicon.
  • the portions A1B andCD of the central bore are clyindrical Whereas the portion BC is conical, whereby the angle of conicity may be approximately 2 and 30' but may also vary from this figure within the purview of the present invention.
  • the electrode 1 is traversed by the electric cable 2 provided with its insulation 3 of any suitable material.
  • the rubber packings 7 and 8 have the form of a truncated cone in which is provided axially a cylindrical passage of which the diameter is substantially equal to that of the cable 2 with its insulation.
  • the packings 7 and 8 are of split construction as shown in the drawing at 9 and 10 in such a manner as to be able to be emplaced by separating the rims of the gap without the necessity of causing the packings 9 and 10 to slide over a large length of the cable.
  • the rubber elements 7 and 8 which constitute the packings are wedged between the electrode 1 and the cable 2. Furthermore, the elements 7 and 8 may be bonded, glued or cemented in any suitable manner to the cable 2 and to the conical portion of the bore of the electrode 1.
  • the rubber elements 7 and 8 serve for fixing or securing the electrode 1 to the cable 2 and at the same time insulate from the corrosive environment the two half-shells or casings 5a and 5b.
  • the conicity of the elements 7, 5a, 5b and 8 is the same as that of the electrode center bore and the external diameters thereof are such that they occupy, within the conical accommodation, exactly the place that one desires.
  • the assembly of the electrode may be effectuated in the following manner which is schematically shown in FIGURES 2 and 4.
  • the two half-shells 5a and 5b are maintained in place either by means of an elastic split ring 6 which had been threaded previously over the cable at the same time as the electrodes or by means of one or several turns of a metallic or non-metallic Wire.
  • the rubber fitting or packing 8 is thereupon placed over the cable 2 near the half-shells or casings 5a and 5b. Thereupon the portion of the cable 2 located between the assembly formed by the two half-shells 5a and 5b and the packing 8 is coated with any suitable known bonding substance such as a glue with a base of the elastomer sold under the designation neoprene, and thereafter the packing 8 is displaced until it touches the half-shell assembly 5a, 5b, 6.
  • any suitable known bonding substance such as a glue with a base of the elastomer sold under the designation neoprene
  • the internal conical surface of the electrode 1 is also coated with the glue or bonding material, and one now moves the assembly constituted by the elements 5a, 5b and 8 into the conical portion of the electrode 1.
  • the assembly is thereafter fixed within the electrode by any appropriate means, for example, by proceeding with a compacting action by means of a round hollow halftube 11 (FIGURE 4) to which is also imparted a rotation in such a manner as to obtain a well distributed progressive wedging.
  • the packing 9 does not have any axial cylindrical passage but is solid as shown in FIGURE 5.
  • FIGURE 4 shows more particularly a device which may be utilized for the last phases of the assembly of the electrodes.
  • the electrode 1 is placed onto a support 12 provided with an aperture and an orifice intended to permit thecable to pass therethrough.
  • the anode arrangement shown in FIGURE 5 and constituted by several electrodes according to the present invention permits to resolve, by the choice of cables with a high mechanical resistance, all of the problems of cathodic protection under which it is subjected to stresses, for example, in the case of immersed constructions.
