Description

Technical Field

[0001] This utility model relates to the field of electrochemical protection technology, specifically to a multi-channel cathodic protection power supply for automated cathodic protection of ship materials. Background Technology

[0002] Ships, offshore platforms, and other facilities are exposed to complex and highly corrosive marine environments for extended periods. Inhibiting the electrochemical corrosion of their metal structures is crucial for preventing structural damage and reducing maintenance costs. Cathodic protection is a common method in ship corrosion prevention engineering. One technique that prevents corrosion by applying an external current is called impressed current cathodic protection (ICCP). This technique applies a controllable reverse current to the hull, shifting the electrode potential of the submerged metal surface in a negative direction, thus creating a cathode and inhibiting corrosion.

[0003] The cathodic protection system based on ICCP has the advantages of controllable power, long life and low pollution. Currently, there are power supply devices that integrate potentiostat and battery. When in use, the power supply and the metal to be protected are connected through multiple sets of electrodes, and the electrochemical protection of the metal to be protected is achieved by power supply.

[0004] In cathodic protection systems, power supply stability is crucial for stable system operation, making power supply thermal management paramount. For cathodic protection systems applied on ships, the variable marine environment renders traditional heat dissipation-only methods insufficient to meet the power supply's stable operation requirements under diverse conditions. Utility Model Content

[0005] Based on the above description, this utility model provides a multi-channel cathodic protection power supply for automated cathodic protection of marine materials, in order to solve the problem that traditional heat dissipation-only methods cannot meet the requirements of stable operation of the power supply in various environments.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This application provides a multi-channel cathodic protection power supply for automated cathodic protection of marine materials, and the technical solution adopted is as follows: A multi-channel cathodic protection power supply for automated cathodic protection of marine materials includes: The housing contains a battery and a main control board. The housing has multiple ports, the battery is connected to the main control board, and the ports are connected to the main control board. A thermal management system, located within the housing, includes a heat dissipation device, a heating device, and a temperature monitoring component connected to the main control board. The heat dissipation device is used to cool the main control board, the heating device is used to heat the main control board, and the temperature monitoring component is used to monitor the temperature of the main control board. The system is adapted to control the operation of the heat dissipation device or the heating device based on the monitoring data from the temperature monitoring component.

[0007] Preferably, the heat dissipation device includes a heat sink and a cooling fan. The heat sink is attached to the main control board, and the cooling fan is connected to the main control board. The cooling fan is used to blow airflow onto the heat sink.

[0008] Preferably, the outer casing is provided with an air inlet and an air outlet that connect the inside and outside, and the outer casing is provided with an air inlet pipe and an air outlet pipe. One end of the air inlet pipe is connected to the air inlet, and the other end is close to the air inlet end of the cooling fan. The air outlet pipe is connected to the air outlet, and a maze channel connecting the inside and outside of the outer casing is formed in the air inlet pipe and the air outlet pipe, respectively.

[0009] Preferably, the intake pipe is provided with a first guide plate and a second guide plate, which are spaced apart along the axial direction of the intake pipe. The first guide plate has a through hole in its center, and the outer edge of the first guide plate is sealed to the inner wall of the intake pipe. The central through hole of the first guide plate forms an airflow channel, and the outer edge of the second guide plate is spaced apart from the inner wall of the intake pipe to form an airflow channel.

[0010] Preferably, the first guide plate is a frustum shape with both ends through, and the second guide plate is a cone shape. Both the first guide plate and the second guide plate are coaxially arranged with the air intake pipe, and the smaller diameter ends of the first guide plate and the second guide plate are close to each other. The first guide plate is close to the end of the air intake pipe that is connected to the air intake port.

[0011] Preferably, the heating device includes a heating element, which is attached to the heat sink and connected to the main control board. The main control board and the heating element are located on opposite sides of the heat sink.

[0012] Preferably, the temperature monitoring component includes a temperature sensor, which is disposed on and connected to the main control board.

[0013] Preferably, the outer casing is provided with a communication interface, which is connected to the main control board.

[0014] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: 1. This application incorporates a thermal management system that monitors the main control board temperature in real time using a temperature monitoring component. When the temperature is too high, the main control board activates a cooling system to lower the board's temperature. Conversely, when the temperature is too low, the main control board activates a heating system to raise the board's temperature, thus ensuring the main control board operates within an optimal temperature range and guaranteeing stable power supply operation. Therefore, the power supply in this application can adapt to various high and low temperature environments, ensuring stable operation of the power supply on ships under diverse environmental conditions.

[0015] 2. This application utilizes an air inlet and an air outlet on the casing to facilitate gas exchange between the inside and outside of the casing. During heat dissipation, the cooling fan draws air from outside the casing into the casing and exits through the air outlet, thus achieving air exchange to cool the main control board. Due to the labyrinth channels within the air inlet and outlet pipes, when the outside temperature is low and the main control board needs to be heated, the labyrinth channels can slow down the gas exchange between the inside and outside of the casing, reducing the rate of heat loss.

[0023] Reference Figure 1 and Figure 2 As shown, this application provides a multi-channel cathodic protection power supply for automated cathodic protection of marine materials, including a housing 1, a battery and a main control board 2 inside the housing 1, and multiple sockets 3 on the housing 1. The battery is connected to the main control board 2, and the sockets 3 are connected to the main control board 2.

[0024] Among them, the connector 3 is an aviation connector 3. Multiple connectors 3 are used to connect eight sets of electrode wires, which are then connected to the material being protected. The power supply provides electrochemical protection to the material being protected.

[0025] The main control board 2 integrates a multi-channel analog-to-digital converter, with multiple ports 3 corresponding to multiple channels. It acquires multiple signals and outputs multiple independent control signals through a time-division multiplexing switch. The main control board 2 integrates an embedded PID control algorithm, which can realize automatic adjustment of the multi-channel reference electrode potential to equalize the cathodic protection potential on the hull surface.

[0026] Reference Figure 2 As shown, the outer casing 1 also includes a communication interface 4 and a touch screen display 5, both connected to the main control board 2. The communication interface 4 includes a USB communication port, a network communication port, and a CAN communication port, which can connect to a host computer to receive external commands and send data to the host computer. The touch screen display 5 allows for manual setting of target parameters without host computer control. Therefore, it supports both host computer control and stand-alone autonomous control modes.

[0027] In stand-alone autonomous control mode, it supports manual setting of PID parameters, and can also dynamically adjust the PID coefficients according to the real-time current through automatic parameter mode.

[0028] The main control board 2 controls multiple output channels simultaneously through a microcontroller, which can reduce power consumption, improve integration, and enhance timing consistency.

[0029] The main control board 2 PCB adopts a four-layer stacked design, with analog signals, ground signals, power signals, and digital signals processed in layers to reduce mutual interference. It also adopts a design with twice the safety line width, and the current lines use a thickened tin plating process to improve the high current carrying capacity.

[0030] Reference Figure 2 As shown, the touch screen and multiple ports 3 are located on the same side of the housing 1, while the communication interface 4 is located on the opposite side. The interior of the housing 1 is divided into two areas by a partition 6: one area is used to house the battery, and the other area is used to house the main control board 2.

[0031] The outer casing 1 is also equipped with a thermal management system. The thermal management system is located inside the outer casing 1 and includes a heat dissipation device, a heating device and a temperature monitoring component connected to the main control board 2. The heat dissipation device is used to cool down the main control board 2, the heating device is used to heat up the main control board 2, and the temperature monitoring component is used to monitor the temperature of the main control board 2. It is suitable for controlling the operation of the heat dissipation device or the heating device according to the monitoring data of the temperature monitoring component.

[0032] Reference Figure 2 and Figure 3 As shown, the heat dissipation device includes a heat sink 7 and a cooling fan 8. The heat sink 7 is attached to the main control board 2, and the cooling fan 8 is connected to the main control board 2. The cooling fan 8 is used to blow airflow onto the heat sink 7. In order to realize the gas exchange between the inside and outside of the outer casing 1, the outer casing 1 is provided with an air inlet 101 and an air outlet 102 that connect the inside and outside. The outer casing 1 is provided with an air inlet pipe 9 and an air outlet pipe 10. One end of the air inlet pipe 9 is connected to the air inlet 101, and the other end is close to the air inlet end of the cooling fan 8. The air outlet pipe 10 is connected to the air outlet 102.

[0033] Reference Figure 2As shown, specifically, multiple heat sinks 7 can be provided and are located in the area of ​​the core components on the main control board 2. Multiple cooling fans 8 are also provided to improve the convection effect. In this embodiment, multiple heat sinks 7 and cooling fans 8 are used for illustration. The heat sinks 7 are located on one side of the main control board 2, and the cooling fans 8 are installed on the side of the main control board 2 near the side of the housing 1 where the connector 3 is located. Air inlets 101 and air outlets 102 are provided on the adjacent two sides of the side of the housing 1 where the connector 3 is located. The air inlets 101 are close to the side of the housing 1 where the connector 3 is located, and the air outlets 102 are close to the side of the housing 1 where the communication interface 4 is located. The number of air intake pipes 9 is the same as the number of air intakes 101. One end of the air intake pipe 9 is connected to the air intake 101, and the other end extends to the cooling fan 8 that is close to the air intake pipe 9.

[0034] When the main control board 2 is cooled, the heat is absorbed by the heat sink 7. The cooling fan 8 starts to draw outside air into the outer casing 1 through the air intake pipe 9 and blows the airflow to the heat sink 7. The airflow carries away the heat from the heat sink 7 and discharges it from the outer casing 1 through the air outlet pipe 10, thus cooling the main control board 2.

[0035] The heating device includes a heating element that is attached to a heat sink 7 and connected to a main control board 2. The main control board 2 and the heating element are located on opposite sides of the heat sink 7. When the main control board 2 is heated, the heating element is powered on and generates heat, which is transferred to the main control board 2 through the heat sink 7, thus achieving the heating function of the main control board 2.

[0036] The temperature monitoring component includes a temperature sensor, which is mounted on and connected to the main control board 2. Specifically, the temperature sensor transmits the detected data to the main control board 2, which then controls the operation of the heat dissipation or heating device based on the temperature value. This enables autonomous temperature control of the main control board 2, ensuring it operates within an optimal temperature range and guaranteeing stable power supply operation.

[0037] Reference Figure 2 and Figure 3 As shown, furthermore, when the main control board 2 needs to be heated, the outside temperature is usually low. In order to reduce the air exchange rate between the inside and outside of the outer casing 1, labyrinth channels connecting the inside and outside of the outer casing 1 are formed in the air inlet pipe 9 and the air outlet pipe 10, respectively. When the outside temperature is low and the main control board 2 needs to be heated, the labyrinth channels can slow down the gas exchange between the inside and outside of the outer casing 1 and reduce the rate of heat loss.

[0038] Reference Figure 3As shown, the intake pipe 9 is provided with a first guide plate 11 and a second guide plate 12. The first guide plate 11 and the second guide plate 12 are spaced apart along the axial direction of the intake pipe 9. The first guide plate 11 has a through hole in its center, and the outer edge of the first guide plate 11 is sealed to the inner wall of the intake pipe 9. The central through hole of the first guide plate 11 forms an airflow channel. The outer edge of the second guide plate 12 is spaced apart from the inner wall of the intake pipe 9 to form an airflow channel. Specifically, the outer edge of the first guide plate 11 is fixed to the inner wall of the intake pipe 9, and the outer edge of the second guide plate 12 is fixed to the outer wall of the intake pipe 9 through a connecting rod (not shown in the figure).

[0039] Reference Figure 3 As shown, the airflow channel formed by the central through hole of the first guide plate 11 and the airflow channel formed between the second guide plate 12 and the inner wall of the intake pipe 9 are staggered to form a labyrinth channel, which increases the path length of the air exchange between the inside and outside of the outer shell 1 through the intake pipe 9, thereby slowing down the natural convection speed of the air.

[0040] Reference Figure 3 As shown, further, in order to reduce the resistance of external air entering the housing 1 through the air intake pipe 9, the first guide plate 11 is a frustum shape with both ends through, and the second guide plate 12 is a cone shape. The first guide plate 11 and the second guide plate 12 are both coaxially arranged with the air intake pipe 9, and the smaller diameter ends of the first guide plate 11 and the second guide plate 12 are close to each other. The first guide plate 11 is close to the end of the air intake pipe 9 that is connected to the air intake port 101.

[0041] With this configuration, when external air enters the housing 1 through the air inlet pipe 9, it first passes through the central through hole of the first guide plate 11, then flows along the outer wall of the second guide plate 12 to the surrounding area, and enters the housing 1 through the gap between the second guide plate 12 and the inner wall of the air inlet pipe 9. The flow resistance in this direction is small.

[0042] Reference Figure 3 As shown, the exhaust pipe 10 also has a first guide plate 11 and a second guide plate 12 forming a labyrinth channel. The difference from the intake pipe 9 is that the second guide plate 12 in the exhaust pipe 10 is closer to the end where the exhaust pipe 10 connects to the exhaust port 102. This arrangement makes the resistance of the air inside the housing 1 being discharged from the housing 1 through the exhaust pipe 10 smaller, while the resistance is larger when flowing in the opposite direction. Therefore, it ensures that when the cooling fan 8 is started, an airflow path is formed between the inside and outside of the housing 1, where the air outside the housing 1 enters the housing 1 through the intake pipe 9 and is discharged from the housing 1 through the exhaust pipe 10, thus ensuring the heat dissipation effect on the main control board 2.

[0043] Furthermore, filters can be installed at the air inlet 101 and the air outlet 102 to prevent debris from entering the housing 1.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
