Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to an adaptive induction heating power supply device. Background Technology

[0002] With the rapid development of large-scale field engineering projects such as oil and gas pipelines and power facilities, the demand for mobile high-power welding equipment is increasing. Traditional welding operations rely on a stable power grid, but in remote mountainous areas, deserts, and other field environments, power grid infrastructure is often lacking. Existing solutions mostly use diesel generator sets as independent power sources, but their output is industrial frequency AC (50 / 60Hz), which cannot directly drive induction heating welding equipment that requires medium-to-high frequency (1-10kHz) operating characteristics. Therefore, the use of power conversion devices is urgently needed.

[0003] Existing solutions separate diesel generator sets, intermediate frequency power cabinets, and welding equipment, requiring multiple specialized vehicles for transportation. After the equipment is in place, complex on-site cable connections and parameter adjustments are also necessary, significantly increasing deployment time and labor costs.

[0004] In addition, the separate equipment is prone to corrosion of electrical components in outdoor environments such as sandstorms, rain and snow, and lacks centralized heat dissipation design, which increases the equipment failure rate by more than 30% under high temperature conditions. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive induction heating power supply device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adaptive induction heating power supply device includes: a cabinet, a diesel generator set, a medium-frequency power supply cabinet, and output terminals. The cabinet has an internal partition that divides the interior space into two independent spaces: a first space and a second space. The partition is a heat-resistant partition. Heat dissipation components are installed in both the first and second spaces. The medium-frequency power supply cabinet is installed in the first space, and the diesel generator set is installed in the second space. The output terminal of the diesel generator set is electrically connected to the input terminal of the medium-frequency power supply cabinet via a wire. The output terminals are installed on the side of the cabinet and are electrically connected to the output terminal of the medium-frequency power supply cabinet.

[0008] As a further embodiment of this utility model, a control component is also included. The control component is installed in the first space. The control component includes a controller and an operation panel. The controller is used to control the operation of the diesel generator set and the medium frequency power supply cabinet.

[0012] As a further embodiment of the present invention, a first air inlet and a first air outlet are provided on one or both sides of the first space. The first air inlet is located at the lower part of the first space, and the first air outlet is located at the upper part of the first space. Louvers are provided on the outer sides of both the first air inlet and the first air outlet, and a first fan is provided on the inner side of the first air outlet.

[0013] As a further embodiment of the present invention, a second air inlet and a second air outlet are provided on one or both sides of the second space.

[0015] As a further embodiment of this utility model, a vertical ladder is provided on one or both sides of the second space.

[0016] As a further embodiment of this utility model, the exhaust pipe of the diesel generator set passes through the top of the second space and communicates with the outside, and the outlet of the exhaust pipe is provided with a movable cover plate.

[0017] The advantages of this utility model are:

[0018] 1. The power generation, conversion, and control equipment are highly integrated, reducing the need for transportation vehicles, and no complicated wiring and debugging are required after the equipment is in place.

[0019] 2. Modular layout: The diesel generator set and the medium frequency power supply cabinet are installed in separate compartments, which reduces the impact of vibration and electromagnetic interference on sensitive components and reduces the equipment failure rate by 50%.

[0020] 3. Dual-space independent air duct design: The generator set and the power cabinet are physically isolated by heat-insulating partitions.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In certain specialized work scenarios, such as laying oil pipelines in the field, building power facilities in remote areas, and repairing geological exploration equipment in the field, high-power welding equipment is often required to ensure the smooth operation of the work. However, field environments typically lack access to the conventional power grid, which poses significant challenges to the use of high-power welding equipment. The traditional solution is to use separate power generation equipment, such as diesel generator sets. However, the direct output of diesel generator sets often fails to meet the specific power requirements of welding equipment and cannot provide a stable power supply. While some solutions exist that simply combine power generation and power consumption equipment, these solutions generally suffer from low integration, large size, and inconvenient transportation. In field operations, transportation conditions are often harsh; large and dispersed equipment not only increases transportation costs and difficulties but also increases the risk of damage during transport. Furthermore, these simply combined devices have deficiencies in power conversion and adaptation, failing to efficiently convert the electricity generated by the diesel generator set into the power required by the welding equipment, resulting in significant energy waste and low operational efficiency. Therefore, this application provides a power supply device that can adapt to outdoor environments without power grid access, efficiently and stably supply power to high-power welding equipment, and is easy to transport and install. The specific solution is as follows.

[0029] like Figures 1 to 3 As shown, an adaptive induction heating power supply device includes: a cabinet 1, a diesel generator set 2, a medium-frequency power supply cabinet 3, and output terminals 5. The cabinet 1 has an internal partition 13 that divides the interior space of the cabinet 1 into two independent spaces: a first space 11 and a second space 12. The partition 13 is a heat-resistant partition made of ceramic fiber composite board, 50mm thick, with a thermal conductivity ≤0.05W / m·K. The first space 11 and the second space 12 are each equipped with heat dissipation components. The medium-frequency power supply cabinet 3 is installed in the first space 11, and the diesel generator set 2 is installed in the second space 12. The output terminal of the diesel generator set 2 is connected to the input terminal of the medium-frequency power supply cabinet 3 via a copper core cable. The output terminal of the medium-frequency power supply cabinet 3 provides medium-frequency power to external welding equipment through the output terminals 5 on the side of the cabinet.

[0030] In this embodiment, the interior of cabinet 1 is divided into two independent spaces by a heat-insulating partition 13, each equipped with a heat dissipation component. The diesel generator set 2 and the medium-frequency power supply cabinet 3 are installed in these two spaces respectively. This design has two advantages: first, it solves the vibration and electromagnetic interference problems caused by the diesel generator set and the power supply cabinet coexisting in a confined space; second, it addresses the heat dissipation management issue, reducing the impact of the large amount of heat generated by the diesel generator set on the equipment in the power supply cabinet.

[0031] In one specific implementation, a control component 4 is also included. This control component is installed within the first space 11 and includes a controller and an operation panel. The controller controls the operation of the diesel generator set 2 and the intermediate frequency power supply cabinet 3. The operation panel is installed on the side panel of the first space 11. In this embodiment, the controller is a Siemens S7-1200, which communicates with the ECU of the diesel generator set 2 and the DSP control board of the intermediate frequency power supply cabinet 3 via a CAN bus. The operation panel is used to display parameters such as generator speed, bus voltage, and output frequency in real time.

[0032] Furthermore, the control component 4 also includes a wireless transceiver terminal, which is electrically connected to the controller and is used to transmit and receive remote control signals. In this embodiment, the wireless transceiver terminal integrates a 4G communication module and communicates with the wireless control terminal 6. The wireless control terminal 6, as shown... Figure 4 As shown, it includes: a display screen 61, an antenna 62, and buttons 63. Operation via the display screen 61 and buttons 63 can achieve functions such as remotely starting and stopping the diesel generator set 2, adjusting the output frequency of the intermediate frequency power cabinet 3, and receiving over-temperature and overload alarm signals.

[0033] For ease of maintenance, a first door 111 for equipment maintenance is provided on the side of the first space 11, and a second door 123 is provided on one or both sides of the second space 12, allowing operators to enter the first space 11 to perform equipment maintenance on the power cabinet and control components. A vertical ladder 124 is provided on one or both sides of the second space 12, and the top of the second space 12 has an opening that is closed by a top plate 121, allowing the top plate 121 to be opened for hoisting operations of the diesel generator set 2 when necessary.

[0034] To solve the heat dissipation problem, the first space 11 adopts a "bottom in, top out" vertical air duct first fan 114, and the second space 12 adopts a "side in, side out" directional air duct second fan 127, combined with heat-insulating baffles to block heat transfer.

[0035] On one or both sides of the first space 11, a first air inlet 112 and a first air outlet 113 are provided according to design requirements. The first air inlet 112 is located at the bottom, and the first air outlet 113 is located at the top. Louvers are installed on the outside of the first air inlet 112 and the first air outlet 113 to prevent foreign objects from entering the cabinet. At the same time, a first fan 114 is installed on the inside of the first air outlet 113 and is tested to ensure good ventilation and heat dissipation.

[0036] On one or both sides of the second space 12, a second air inlet 122 and a second air outlet 125 are provided according to the structural characteristics of the diesel generator set 2. Since the temperature on the engine side is much higher than that on the generator side, the second air inlet 122 is located on the generator side, and the second air outlet 125 is located on the engine side. Similarly, louvers are installed on the outside of the second air inlet 122 and the second air outlet 125, and a second fan 127 is installed on the inside. The fan automatically adjusts the air volume according to the K-type thermocouple monitoring the exhaust pipe temperature to ensure that the diesel generator set 2 can receive sufficient heat dissipation during operation.

[0037] In one specific implementation, the exhaust pipe 21 of the diesel generator set 2 passes through the top of the second space 12 and communicates with the outside. To prevent rainwater backflow, the outlet of the exhaust pipe 21 is provided with a movable cover plate 22. The movable cover plate 22 is hinged and equipped with a high-temperature resistant sealing ring.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity.
