Description

Technical Field

[0001] The present invention relates to the technical field of oilfield power grids, in particular to an anti-electrical corrosion testing device for an ADSS optical cable of an oilfield power grid. Background Art

[0002] During the construction of the oil field, it is necessary to equip it with grid ADSS optical cables around it. The optical cables are made of metal. At the same time, there is a lot of water vapor around the oil field. When the metal is in a relatively moist position, an electric corrosion reaction often occurs on the surface of the optical cable. The electric corrosion reaction is when the metal is placed in an aqueous solution or a humid atmosphere. A micro battery will be formed on the metal surface, also known as a corrosion battery. An oxidation reaction occurs on the anode, causing the anode to dissolve, and a reduction reaction occurs on the cathode. Generally, it only plays the role of transferring electrons. The formation of the corrosion battery is mainly due to the adsorption of moisture in the air on the metal surface to form a water film, which causes CO2, NO2, SO2, etc. in the air to dissolve in this water film to form an electrolyte solution.

[0003] In order to protect the optical cable, a covering layer needs to be coated on the surface of the optical cable. However, since the anti-electrocorrosion performance of the surface of the optical cable is unknown, the optical cable is easily damaged by the electrocorrosion rate after being used in the oil field.

[0016] Compared with the prior art, the beneficial effects of the invention are:

[0017] 1) During operation, the contacts are in contact with the surface of the optical cable through the provided contacts. The contacts transmit the generated current to the inside of the electromagnet, causing the electromagnet to generate magnetism. The magnetism is the same as that of the magnetic block, so that the magnetic block moves under the action of the electromagnet. The magnetic block screw is threadedly connected to the rotating ring, and the rotating ring is rotatably connected to the inside of the dial. As a result, after the magnetic block screw moves, it drives the rotating ring to rotate, and the pointer points to the scale line on the inner wall of the dial after the rotating ring rotates.

When the bottom end of the pressure head is clamped with the outer wall of the optical cable, the second slider is subjected to the resistance of the pressure head and cannot continue to slide inside the second slide groove, thereby pushing the ring to move on the surface of the optical cable, and the pressure head clamps the optical cable, so that after the ring moves, the two ends of the optical cable are straightened, thereby preventing the optical cable from bending inside the cable groove, and then keeping the optical cable in close contact with the inner wall of the cable groove, thereby increasing the contact area between the optical cable and the cable groove, and then increasing the contact area with the electrolyte solution, thereby improving the measurement accuracy of the anti-electrical corrosion strength result of the optical cable;

[0019] 3) During operation, after the set pressing screw moves outward, it drives the push rod to move away from the pressure rod, and then under the elastic force of the pressure rod spring, the pressure rod spring drives the plug to move outward, so that the plug is disengaged from the external connecting hole, and then the motor is turned on, and the output gear of the motor is engaged with the teeth, so that the motor drives the rotating drum to rotate, so that the internal connecting hole on the rotating drum rotates to a position corresponding to the external connecting hole. At this time, the electrolyte solution in the liquid storage tank contacts the surface of the optical cable inside the cable trough through the external connecting hole and the internal connecting hole, and the connection and disconnection of the optical cable and the electrolyte solution are controlled by the rotating drum, so that the electrolyte solution only contacts the part to be detected of the optical cable, thereby improving the protection effect on other positions of the optical cable.

After the liquid storage tank 3011 is connected to the inside of the cable groove 2, turn the handle 3015. Since the inner piston 3016 is connected to the inner thread of the outer piston 3013, the inner piston 3016 enters the liquid storage tank 3011, and then presses the electrolyte solution inside the liquid storage tank 3011 into the inside of the cable groove 2, fully contacting the surface of the optical cable 6.

One side of the push rod 3028 is in contact with the top of the pressure rod 30211.

[0031] After the detector 1 is fixed on the optical cable 6, the pressing screw 3027 is screwed out, and the pressing screw 3027 is rotatably connected to the push rod 3028, so that after the pressing screw 3027 moves outward, it drives the push rod 3028 to move outward inside the slide groove 3026, and one side of the push rod 3028 contacts the pressing rod 30211, so that the push rod 3028 moves away from the pressing rod 30211, so that the pressure on one end of the pressing rod 30211 disappears, and then under the elastic force of the pressing rod spring 30212, the pressing rod spring 30212 drives the plug 30210 to move outward, so that the plug 30210 is connected to the external communicating hole 301 7 is disengaged, and then the motor 3023 is turned on. The output gear of the motor 3023 is meshed with the teeth 3022, so that the motor 3023 drives the rotating drum 3021 to rotate, so that the internal communicating hole 3024 on the rotating drum 3021 rotates to a position corresponding to the external communicating hole 3017. At this time, the electrolyte solution in the liquid storage tank 3011 contacts the surface of the optical cable 6 inside the cable trough 2 through the external communicating hole 3017 and the internal communicating hole 3024. The optical cable 6 and the electrolyte solution are connected and disconnected through the rotating drum 3021, so that the electrolyte solution only contacts the part to be detected of the optical cable 6, thereby improving the protection effect on other parts of the optical cable 6.
