Description

Technical Field

[0001] This utility model relates to the technical field of power frequency conversion control equipment for marine platforms, and specifically to a dual power frequency conversion control device for marine platforms. Background Technology

[0002] Offshore platforms are structures that provide production and living facilities for activities such as drilling, oil production, cargo collection, observation, navigation, and construction at sea. Patent No. CN202022388729.4 discloses a dual-power-supply frequency converter control cabinet and a dual-power supply system. This system uses dual power supply lines, with one line consisting of a transformer and rectifier / frequency converter, and the other consisting of power supply equipment, serving as backups. The dual-power switching switch allows for switching between power lines, improving system reliability and reducing maintenance costs for the control cabinet and its power supply system. However, during the use of dual-power frequency converter control equipment on offshore platforms, the high humidity and significant diurnal temperature variations cause humid air to easily penetrate and condense inside the control equipment at night, potentially affecting its performance. Therefore, we propose a dual-power frequency converter control device for offshore platforms. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a dual-power frequency conversion control device for marine platforms.

[0004] The technical solution adopted by this utility model to solve its technical problem is a dual-power frequency converter control device for marine platforms, including a cabinet. The inner side of the cabinet is equipped with a perforated partition for dividing space, and the cabinet is equipped with the main body of the dual-power frequency converter control equipment for marine platforms. The top surface of the cabinet is equipped with a frame plate that is connected to the cabinet, and a graphite heat-conducting plate for absorbing heat is installed at the connection between the frame plate and the cabinet. The inner side of the frame plate is equipped with a support bracket for support by bolts, and the outer side of the support bracket is equipped with a fan for heat dissipation, and there are multiple sets of fans.

[0005] Both sides of the outer periphery of the cabinet are bolted with a frame base for support, and an adjustable slide plate is slidably installed inside the frame base. The outer periphery of the slide plate and the outer sides of the frame base are provided with multiple sets of slotted holes for ventilation. The inner side of the frame base is equipped with multiple sets of miniature electric push rods for pushing the slide plate to move up and down.

[0006] By adopting the above technical solution, during the use of the dual-power frequency converter control equipment for marine platforms, the perforated partition inside the cabinet can divide a space channel that facilitates ventilation. Then, the heat generated by the main body of the dual-power frequency converter control equipment can easily pass through the holes in the perforated partition and be dissipated. The graphite heat-conducting plate at the connection between the frame plate and the cabinet can easily absorb heat and conduct and evaporate the heat to the inside of the frame plate. Subsequently, the operation of multiple sets of fans on the bracket inside the frame plate can easily blow the evaporated heat out of the frame plate, and fresh air can easily enter from the opening on the other side of the frame plate, thus facilitating heat dissipation.

[0007] During the use of dual-power frequency converter control equipment on offshore platforms, when the internal temperature of the cabinet is too high and cannot be dissipated, multiple sets of miniature electric push rods inside the frame can operate and easily push the sliding plate inside the frame to move. This allows the strip holes on the outside of the sliding plate to correspond with the strip holes on both sides of the outer perimeter of the frame, thus forming a channel. This allows the main body of the dual-power frequency converter control equipment inside the cabinet to receive auxiliary heat dissipation and improve the efficiency of heat dissipation. At the same time, when the temperature drops, the miniature electric push rods can operate and drive the sliding plate to move. This allows the strip holes between the sliding plate and the frame to be misaligned, and the sliding plate can block the strip holes on the frame. This allows the main body of the dual-power frequency converter control equipment inside the cabinet to continue to operate stably and reduces the impact caused by humid air directly entering the cabinet during cooling.

[0008] Specifically, a temperature sensor for measurement is installed between the porous partition and the cabinet.

[0009] By adopting the above technical solution, the temperature sensor can easily measure the heat inside the cabinet. When the heat is high, it can easily feed back to the controller on the outside of the cabinet, and use the controller to control the operation of the miniature electric push rod.

[0010] Specifically, a protective rubber pad is adhered to the bottom surface of the skateboard.

[0011] By adopting the above technical solution, the rubber pad has a certain degree of elasticity, which helps to reduce the situation where the skateboard rubs against the frame when it slides inside the frame, thus reducing the damage caused by collisions.

[0012] Specifically, the graphite heat-conducting plate is equipped with heat dissipation fins on the side near the frame plate to assist in heat dissipation.

[0013] By adopting the above technical solution, the heat dissipation fin plate can facilitate the evaporation of heat conducted by the graphite heat-conducting plate and improve the heat evaporation efficiency.

[0014] Specifically, the two open ends on the outer periphery of the frame plate are each fitted with a filter screen plate for protection by bolts.

[0015] By adopting the above technical solution, the filter screen can easily protect the open ends on both sides of the outer periphery of the frame plate, which can reduce the situation of debris entering the interior of the frame plate and make the internal structure of the frame plate operate more stably.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a perforated partition, a dual-power frequency converter control equipment body, a frame plate, a graphite heat-conducting plate, a bracket, and a fan, allows for the use of the dual-power frequency converter control equipment on offshore platforms. During the use of the dual-power frequency converter control equipment, the perforated partition inside the cabinet can create a space channel that facilitates ventilation. The heat generated by the dual-power frequency converter control equipment body during operation can easily pass through the holes in the perforated partition and be dissipated. The graphite heat-conducting plate at the connection between the frame plate and the cabinet can easily absorb heat and conduct it to the inside of the frame plate. Subsequently, the operation of multiple sets of fans on the bracket inside the frame plate can easily blow the dissipated heat out of the frame plate, and fresh air can easily enter from the opening on the other side of the frame plate, thus facilitating heat dissipation.

[0018] 2. The technical solution of this application, through the design of a frame base, sliding plate, slotted holes, and miniature electric push rods, enables multiple sets of miniature electric push rods inside the frame base to operate and easily push the sliding plate inside the frame base when the internal temperature of the cabinet is too high and cannot be dissipated. This allows the slotted holes on the outside of the sliding plate to correspond with the slotted holes on both sides of the outer perimeter of the frame base, thus forming a channel. This allows the main body of the dual-power frequency converter control equipment inside the cabinet to receive auxiliary heat dissipation and improve the efficiency of heat dissipation. At the same time, when the temperature decreases, the miniature electric push rods can operate and drive the sliding plate to move, allowing the slotted holes between the sliding plate and the frame base to be misaligned. The sliding plate can also block the slotted holes on the frame base, thereby enabling the main body of the dual-power frequency converter control equipment inside the cabinet to continue to operate stably and reducing the impact caused by humid air directly entering the cabinet during cooling.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a dual-power frequency converter control device for an offshore platform, comprising a cabinet 1, a perforated partition 2 for dividing space on the inner side of the cabinet 1, and a main body 3 for a dual-power frequency converter control device for an offshore platform inside the cabinet 1. A frame plate 4 connected to the cabinet 1 is mounted on the top surface of the cabinet 1, and a graphite heat-conducting plate 5 for heat absorption is mounted at the connection between the frame plate 4 and the cabinet 1. A support bracket 6 for support is mounted on the inner side of the frame plate 4 by bolts, and a fan 7 for heat dissipation is mounted on the outer side of the support bracket 6, and there are multiple sets of fans 7. Frame seats 8 for support are mounted on both sides of the outer periphery of the cabinet 1 by bolts, and a sliding plate 9 for adjustment is slidably installed inside the frame seat 8. Slotted holes 10 for ventilation are opened on the outer periphery surface of the sliding plate 9 and the outer periphery side wall surfaces of the frame seat 8, and there are multiple sets of slotted holes 10. Miniature electric push rods 11 for pushing the sliding plate 9 to rise and fall are mounted on the inner side of the frame seat 8, and there are multiple sets of miniature electric push rods 11.

[0026] When using the dual-power frequency converter control equipment for marine platforms, the perforated partition 2 inside the cabinet 1 can create a convenient ventilation space. The heat generated by the main body 3 of the dual-power frequency converter control equipment can easily pass through the holes in the perforated partition 2 and be dissipated. The graphite heat-conducting plate 5 at the connection between the frame plate 4 and the cabinet 1 can easily absorb heat and conduct it to the inside of the frame plate 4. Subsequently, the operation of multiple fans 7 on the bracket 6 inside the frame plate 4 can easily blow the dissipated heat out of the frame plate 4, and fresh air can easily enter from the opening on the other side of the frame plate 4, thus facilitating heat dissipation.

[0027] During the use of the dual-power frequency converter control equipment for offshore platforms, when the temperature inside the cabinet 1 is too high and cannot be dissipated, multiple sets of miniature electric push rods 11 inside the frame 8 can operate and easily push the slide plate 9 inside the frame 8 to move. This allows the strip holes 10 on the outside of the slide plate 9 to correspond with the strip holes 10 on both sides of the outer periphery of the frame 8, thus forming a channel. This allows the main body 3 of the dual-power frequency converter control equipment inside the cabinet 1 to receive auxiliary heat dissipation and improve the efficiency of heat dissipation. At the same time, when the temperature decreases, the miniature electric push rods 11 can operate and drive the slide plate 9 to move. This allows the strip holes 10 between the slide plate 9 and the frame 8 to be misaligned, and the slide plate 9 to block the strip holes 10 on the frame 8. This allows the main body 3 of the dual-power frequency converter control equipment inside the cabinet 1 to continue to operate stably and reduces the impact caused by humid air directly entering the cabinet 1 during cooling.

[0028] like Figure 2 As shown, a temperature sensor 14 for measurement is installed between the porous partition 2 and the cabinet 1.

[0029] When in use, the temperature sensor 14 can easily measure the heat inside the cabinet 1. When the heat is high, it can easily feed back to the controller on the outside of the cabinet 1, and use the controller to control the operation of the miniature electric push rod 11.

[0030] like Figure 3 As shown, a protective rubber pad 12 is adhered to the bottom surface of the skateboard 9.

[0031] When in use, the rubber pad 12 has a certain degree of elasticity, which helps to reduce the situation where the slide plate 9 rubs against the frame 8 when it slides inside the frame 8, thus reducing the risk of damage caused by collision.

[0032] like Figure 2 As shown, the graphite heat-conducting plate 5 is equipped with a heat dissipation fin plate 13 for auxiliary heat dissipation on the side near the frame plate 4.

[0033] During use, the heat dissipation fin plate 13 facilitates the evaporation of heat conducted by the graphite heat conduction plate 5 and improves the heat evaporation efficiency.

[0034] like Figure 1 As shown, filter screens 15 for protection are bolted to the open ends on both sides of the outer periphery of the frame plate 4.

[0035] When in use, the filter plate 15 can protect the openings on both sides of the outer periphery of the frame plate 4, which helps to reduce the entry of debris into the frame plate 4 and makes the internal structure of the frame plate 4 operate more stably.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the dual-power frequency converter control equipment for offshore platforms, the perforated partition 2 inside the cabinet 1 can create a convenient ventilation space. Then, the heat generated by the main body 3 of the dual-power frequency converter control equipment during operation easily passes through the holes in the perforated partition 2 for heat dissipation. Furthermore, the graphite heat-conducting plate 5 at the connection between the frame plate 4 and the cabinet 1 easily absorbs heat and conducts it to the interior of the frame plate 4. Subsequently, the multiple sets of fans 7 on the internal support 6 of the frame plate 4 easily blow the evaporated heat out of the frame plate 4, and fresh air easily enters from the opening on the other side of the frame plate 4, thus facilitating heat dissipation. The graphite heat-conducting plate 5 also conveniently seals the connection between the frame plate 4 and the cabinet 1, reducing the impact of external humid air on the internal structure of the cabinet 1. Simultaneously, when the internal temperature of the cabinet 1... When the temperature is too high and cannot be evaporated, multiple sets of miniature electric push rods 11 inside the frame base 8 can operate and easily push the slide plate 9 inside the frame base 8 to move. This allows the strip holes 10 on the outside of the slide plate 9 to correspond with the strip holes 10 on both sides of the outer periphery of the frame base 8, thus forming a channel. This allows the main body 3 of the dual-power frequency converter control equipment inside the cabinet 1 to provide auxiliary heat dissipation and improve the efficiency of heat evaporation. At the same time, when the temperature drops, the miniature electric push rods 11 can operate and drive the slide plate 9 to move. This allows the strip holes 10 between the slide plate 9 and the frame base 8 to be misaligned, and the slide plate 9 to block the strip holes 10 on the frame base 8. This allows the main body 3 of the dual-power frequency converter control equipment inside the cabinet 1 to continue to operate stably and reduces the impact caused by humid air directly entering the cabinet 1 during cooling. Subsequently, this allows the dual-power frequency converter control equipment for offshore platforms to operate more stably.
