Description

Technical Field

[0001] This utility model relates to the field of cathodic protection, and in particular to a pipeline cathodic protection device based on differential pressure power generation within a pressure regulating metering cabinet. Background Technology

[0002] Cathodic protection is a type of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, making the protected structure a cathode, thereby inhibiting electron migration that occurs during metal corrosion, thus avoiding or reducing corrosion.

[0003] Buried pipelines are mainly used for oil pipelines, gas pipelines, and steel water pipes. Existing cathodic protection power supply equipment requires power transformers and rectifiers for regulation, and specialized sites need to be built to arrange the relevant equipment, making cathodic protection of buried pipelines quite difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a pipeline cathodic protection device based on differential pressure power generation within a pressure regulating metering cabinet. This device does not require site adaptation for installation and protects buried pipelines through adaptive adjustment of the cathodic protection machine.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A pipeline cathodic protection device based on differential pressure power generation within a pressure regulating metering cabinet, applied to pipelines, includes a differential pressure generator, a battery, and a cathodic protection unit within the pressure regulating metering cabinet, wherein:

[0007] The differential pressure generator is connected to the storage battery and then connected to the cathode protection device for power supply;

[0008] The cathodic protection device is equipped with an output cathodic protection power interface, which is connected to the pipeline via a cathode cable.

[0009] In some embodiments, the cathode protection device is further provided with a zero-position cathode interface and a reference electrode interface. The zero-position cathode interface is connected to the pipeline via a connected zero-position cable, and the reference electrode interface is connected to the pipeline via a connected reference cable.

[0010] In some embodiments, the cathodic protection device is further provided with an output anode interface, which is connected to a shallow buried anode bed or a deep well anode bed.

[0011] In some embodiments, the cathode protection device is further provided with an RS485 interface for communication.

[0012] In some embodiments, the pipeline comprises a steel pipeline.

[0013] In some embodiments, the differential pressure generator is an explosion-proof differential pressure generator.

[0014] In some embodiments, the battery is an explosion-proof UPS battery.

[0015] The beneficial effects of the differential pressure power generation cathodic protection device based on a voltage regulating metering cabinet provided by this utility model are:

[0016] Cathodic protection for buried pipelines is achieved through the cooperation of a differential pressure generator, a storage battery, and a cathodic protection device. The UPS connects the power line to the cathodic protection device, which in turn connects to the protected pipeline. In areas without external power access, the cathodic protection device outputs a cathode interface that connects to the corresponding pipeline through a connected cathode cable to ensure corrosion protection of buried metal structures.

[0017] By also providing a zero-position female interface and a reference electrode interface to the cathodic protection machine, and by connecting the zero-position female interface to the pipeline via a zero-position cable, and the reference electrode interface to the pipeline via a reference cable, adaptive protection can be ensured for pipelines with different needs and categories.

[0018] The cathodic protection device is also equipped with an output anode interface, which can be connected to a shallow buried anode bed or a deep well anode bed to ensure that the anode output can meet the needs of the corresponding scenarios and improve the utilization rate.

[0019] Specifically, this application also allows for the automatic adjustment of various parameters of the cathodic protection power supply device according to the set parameters on the cathodic protection machine, so as to ensure the anti-corrosion effect of the buried metal structure. At the same time, with the help of the communication module, the frequency of manual inspection and debugging can be reduced. Attached Figure Description

[0023] Example

[0024] like Figure 1 As shown in the figure, this embodiment provides an exemplary pipeline cathodic protection device based on differential pressure power generation within a pressure regulating metering cabinet.

[0025] Figure 1 In this context, a differential pressure generator and cathodic protection device based on a voltage regulating metering cabinet is applied to pipelines. The voltage regulating metering cabinet contains a differential pressure generator, a battery, a cathodic protection unit, and a UPS. The power lines are connected to the cathodic protection unit, which is then connected to the pipeline for protection. The differential pressure generator is connected to the battery and then connected to the voltage regulating metering cabinet for power supply. The cathodic protection unit is equipped with an output cathode interface, which is connected to the pipeline through a cathode cable.

[0026] The differential pressure generator is preferably an explosion-proof differential pressure generator, and the battery is preferably an explosion-proof UPS battery.

[0027] Please refer to Figure 2 , Figure 2 This is a schematic diagram of an exemplary differential pressure generator structure provided in an embodiment of this application. In the diagram, the explosion-proof differential pressure generator generates electricity using the differential pressure. The generated current is transmitted to the explosion-proof UPS battery for storage. The explosion-proof UPS battery connects the power line to the cathodic protection device and provides it with power, so that the voltage regulating metering cabinet and the cathodic protection device do not need to be connected to an external power source.

[0028] To meet the actual protection needs of pipelines with different corrosion levels and different categories, the cathodic protection machine is also equipped with a zero-position female interface and a reference electrode interface. The zero-position female interface is connected to the pipeline through a zero-position cable, and the reference electrode interface is connected to the pipeline through a reference cable.

[0029] The pipeline may include a steel pipeline. The output cathode interface is connected to the top side of the steel pipeline through a connected cathode cable. The zero-position cathode interface is connected to the steel pipeline from the top side through a connected zero-position cable and the reference electrode interface is connected to the reference cable through a connected reference cable, so as to realize adaptive protection for pipelines with different needs and categories.

[0030] To accommodate diverse applications of production capacity, the cathodic protection unit is also equipped with an output anode interface. This output anode interface can be connected to a shallow-buried anode bed or a deep-well anode bed to ensure that the anode output can meet the needs of the corresponding application scenarios and improve utilization.

[0031] In addition, to better facilitate communication and determine the overall operating status of the device, the cathodic protection unit is also equipped with an RS485 interface for communication. By adjusting the various parameters of the cathodic protection power supply equipment according to the set parameters on the voltage regulating metering cabinet, the corrosion protection effect of the buried metal structure can be guaranteed. At the same time, with the help of the communication module, the frequency of manual inspection and debugging can also be reduced.
