Description

Technical Field

[0001] The present invention relates to the technical field of offshore platform power storage and power supply, and in particular to a power cabinet for an offshore platform wind-solar power storage and power supply system. Background Art

[0002] An offshore platform is a building that is high above the sea, such as an offshore oil and gas development platform, an offshore wind power station, etc. When these offshore platforms are working, the power storage and power supply system can ensure the normal operation of the platform and the normal operation of the platform equipment. In the offshore platform power storage and power supply system, the power cabinet is one of the important devices;

[0003] When the offshore platform power cabinet is working, it plays the role of power distribution and control, which facilitates the stable operation of different power-consuming equipment. At the same time, it also plays the role of protecting the power equipment. When the power equipment is overloaded, the protection components in the power cabinet will act quickly to cut off the fault circuit and prevent the fault from expanding.

[0004] When the power cabinet on an offshore platform is used for a long time, a high load may occur. At this time, the temperature inside the power cabinet will rise and exceed the normal operating temperature of the electrical components, making it inconvenient for the power cabinet to continue working, resulting in power system failure;

[0005] In order to overcome the above defects, prior art 1 (Chinese patent with application number CN202410422155.8 and application date 2024-04-09) is a moisture-proof and heat-dissipating power cabinet, which can accelerate the air flow rate in the placement cavity through the air circulation channel of the ventilation part and the ventilation mechanism on the cabinet body, thereby ensuring the cooling and heat dissipation performance of the electrical equipment. At the same time, when the external humidity is too high, the ventilation mechanism can be shielded by the shielding part to prevent water vapor from easily entering the placement cavity, reducing the possibility of short circuit of the electrical equipment;

[0006] Another example of prior art 2 (Chinese patent application number CN201610231836.1, application date 2016-04-07) is a buffer heat dissipation power cabinet, which has a simple structure and is easy to operate, greatly facilitates the operation of the power cabinet, improves the safety of the power cabinet, and has both heat dissipation and sand resistance; it has good shock absorption and buffering effects, long service life, and has a good fixing effect on the cabinet body;

[0007] And prior art 3 (Chinese patent with application number CN201910545227.7 and application date 2019-06-21) is a power cabinet that is easy to dissipate heat, which has the advantages of heat dissipation, cleaning and insect repellent, and improves the safety of the power cabinet;

[0008] After long-term use, dust and grit will accumulate on the heat dissipation vents on the surface of the device shell, which will affect the subsequent heat dissipation function of the device.

[0018] A heat dissipation net, wherein the heat dissipation net is fixedly connected to the back of the shell, and a limit rod is fixedly connected to the back of the shell, and an upper connection block is sleeved on the surface of the limit rod;

[0019] A protection frame is fixedly connected to the lower surface of the upper connecting block, and a protection net is fixedly connected to the inner wall of the protection frame.

[0020] Preferably, a push plate is fixedly connected to the surface of the connecting shaft, and the push plate has a figure "8" structure when viewed from above, and the movable plates are symmetrically distributed about the center of the housing.

[0021] Preferably, the upper surface of the force-bearing plate is inclined, and the upper surface of the force-bearing plate is in contact with the lower surface of the movable plate, and the knocking rods are distributed at equal intervals on the upper surface of the movable plate.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: the power cabinet for the offshore platform wind, solar and storage power supply system adopts a new structural design, and optimizes the heat dissipation effect of the shell by setting a baffle that can be opened and closed intermittently. At the same time, a knocking rod is set to make the protection plate vibrate slightly, so that less rainwater is on the surface of the protection plate in rainy days. In addition, a vibration structure of the protection frame is set to shake off the dust on the protection net, ensuring the normal operation of the protection net. The specific contents are as follows:

[0030] (1) The power cabinet used in the offshore platform wind, solar and storage power supply system senses the temperature inside the shell through the sensor during use. When the temperature inside the shell is too high, the motor starts, and the baffle swings back and forth around the inner rod, so that the ventilation network is in an intermittent opening and closing state, which optimizes the heat dissipation effect of the shell;

[0031] Furthermore, when there is heavy rain outside, the protective plate will drain the rain quickly through its own inclined surface, so that the rain will not remain on the protective plate;

[0032] Furthermore, when the outdoor rain is heavy, the motor will also work. At this time, the connecting shaft drives the push plate to rotate synchronously. At this time, the force-bearing plate performs reciprocating linear motion in the horizontal direction under the action of the thrust, the cross bar and the first spring, and then the movable plate performs reciprocating linear motion in the vertical direction under the action of the thrust of the force-bearing plate, its own gravity and the limit column. At this time, the movable plate will repeatedly hit the inner wall of the protection plate through the knocking rod, so that the protection plate is in a vibrating state, so that the rainwater is quickly drained and the outer shell is protected;

[0033] (2) The power cabinet used in the offshore platform wind, solar and storage power supply system, when the shell is working, the shell dissipates heat through the heat dissipation net and the protective frame. In this process, the protective net prevents large particles of impurities from entering the shell, thus playing a protective role;

[0034] Furthermore, when the connecting shaft rotates, the connecting shaft drives the long pin to rotate inside the shell through the pulley. When the long pin rotates, the connecting plate and the second magnet will rotate synchronously. At this time, the protective frame makes reciprocating linear motion in the horizontal direction under the action of the first magnet and the second magnet, the limit rod and the second spring. At this time, the protective frame and the protective net are in a vibrating state, and the dust on the protective net will be shaken off, so that the protective frame and the protective net can work normally, and poor heat dissipation will not occur, thereby optimizing the heat dissipation and cooling effect.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1: When heat dissipation is required, the ventilation net 15 can be opened and closed intermittently, and the ventilation net 15 and the heat dissipation net 21 cooperate to optimize the heat dissipation and cooling effect, such as Figure 1-Figure 6 As shown:

[0049] It includes a shell 1 and a door panel 4, the lower surface of the shell 1 is fixedly connected to a bottom plate, the upper surface of the shell 1 is fixedly connected to a protection plate 2, the inner wall of the shell 1 is fixedly connected to a sensor 3, the upper surface of the shell 1 is convex, the left and right sides of the protection plate 2 are inclined, the door panel 4 is hingedly connected to the front side of the shell 1, and the top inner wall of the shell 1 is bolted to a motor 5, and the motor 5 and the sensor 3 are connected by electrical signals;

[0050] A power cabinet for an offshore platform wind, solar, and storage power supply system, further comprising:

[0051] A connecting shaft 6, which is fixedly connected to the output end of the motor 5, and a pulley 20 is sleeved on the surface of the connecting shaft 6; a vertical plate 8, which is fixedly connected to the upper surface of the housing 1, and a cross bar 10 is fixedly connected to the outer wall of the vertical plate 8, and a force-bearing plate 9 is sleeved on the surface of the cross bar 10;

[0052] A limit post 12, the limit post 12 is fixedly connected to the upper surface of the shell 1, and a movable plate 13 is slidably provided on the surface of the limit post 12, and a knocking rod 14 is fixedly connected to the upper surface of the movable plate 13, an inner rod 18, the inner rod 18 is rotatably provided inside the raised position on the upper surface of the shell 1, and a baffle 16 is fixedly connected to the surface of the inner rod 18, and a ventilation net 15 is fixedly connected to the upper surface of the shell 1;

[0053] The heat dissipation net 21 is fixedly connected to the back of the shell 1, and the back of the shell 1 is fixedly connected to a limiting rod 27, and the surface of the limiting rod 27 is sleeved and connected with an upper connecting block 28, a protective frame 22, the protective frame 22 is fixedly connected to the lower surface of the upper connecting block 28, and the inner wall of the protective frame 22 is fixedly connected with a protective net 24.

[0054] The surface of the connecting shaft 6 is fixedly connected with a push plate 7, and the push plate 7 is a figure "8" structure when viewed from above, the movable plate 13 is symmetrically distributed about the center of the shell 1, the upper surface of the force-bearing plate 9 is inclined, and the upper surface of the force-bearing plate 9 is in contact with the lower surface of the movable plate 13, and the knocking rods 14 are evenly spaced on the upper surface of the movable plate 13.

[0055] A first spring 11 having an elastic reset function is fixedly connected to the surface of the force-bearing plate 9, and the other side of the first spring 11 is fixedly connected to the outer wall of the vertical plate 8. The end of the cross bar 10 is convex. A traction chain 17 is fixedly connected to the lower surface of the movable plate 13, and the other side of the traction chain 17 is fixedly connected to the upper surface of the baffle 16, and the baffle 16 corresponds one-to-one to the ventilation net 15.

[0056] When the housing 1 works for a long time and the temperature inside the housing 1 rises, the sensor 3 starts the motor 5. When the motor 5 works, the motor 5 drives the connecting shaft 6 to rotate. At this time, the connecting shaft 6 drives the push plate 7 to rotate synchronously. When the push plate 7 rotates to push the force plate 9, the force plate 9 moves in the direction of squeezing the first spring 11. At this time, the force plate 9 pushes the movable plate 13, so that the movable plate 13 and the knocking rod 14 rise. When the push plate 7 continues to rotate until it is no longer in contact with the force plate 9, the force plate 9 returns to its original position under the action of the first spring 11, and the force plate 9 moves to When moving back, the movable plate 13 descends under the action of its own gravity, and the above process is repeated. The force-bearing plate 9 performs reciprocating linear motion in the horizontal direction under the action of the thrust, the cross bar 10 and the first spring 11, and the movable plate 13 performs reciprocating linear motion in the vertical direction under the action of the thrust of the force-bearing plate 9, its own gravity and the limit column 12. At this time, the movable plate 13 drives the baffle 16 to rotate around the inner rod 18 through the traction chain 17. When the baffle 16 rotates, the ventilation net 15 is in an intermittent opening and closing state, which optimizes the heat dissipation effect of the housing 1;

[0057] On rainy days, the protection plate 2 allows rainwater to drain quickly, and the motor 5 will also work. At this time, the movable plate 13 will still make reciprocating linear motion in the vertical direction, and then the movable plate 13 will hit the protection plate 2 again and again in the vertical direction through the knocking rod 14, so that the rainwater on the protection plate 2 can be drained more quickly, thereby protecting the shell 1.

[0058] Embodiment 2: Different from Embodiment 1, by providing a protective frame 22 and a protective net 24, when the heat dissipation net 21 is ventilated, no impurities will enter the interior of the housing 1. At the same time, a vibration structure of the protective frame 22 is provided to make dust fall from the heat dissipation net 21. Figure 7-Figure 11 As shown:

[0059] The back of the shell 1 is convex, and a long pin 19 is rotatably connected to the inside of the convex position on the back of the shell 1. The other side of the pulley 20 is sleeved and connected to the surface of the long pin 19. The end of the long pin 19 is fixedly connected to a connecting plate 25, and the upper surface of the connecting plate 25 is fixedly connected to a second magnet 26.

[0060] The upper surface of the protective frame 22 is convex, and the surface at the convex position of the protective frame 22 is fixedly connected with a first magnet 23 corresponding to the second magnet 26, and the second magnet 26 is distributed at equal angles on the upper surface of the connecting plate 25, and the magnetic poles of the first magnet 23 and the second magnet 26 at adjacent positions are the same.

[0061] The upper connecting block 28 is symmetrically distributed about the center of the protective frame 22. The end of the limiting rod 27 is convex. The surface of the limiting rod 27 is fixedly connected to a second spring 29 that plays an elastic reset role, and the other side of the second spring 29 is fixedly connected to the inner wall of the upper connecting block 28.

[0062] When the shell 1 is working, the shell 1 dissipates heat through the heat dissipation net 21 and the protection frame 22. In this process, the protection net 24 prevents large particles of impurities from entering the shell 1, thereby playing a protective role. During the operation of the motor 5, when the connecting shaft 6 rotates, the connecting shaft 6 drives the long pin 19 to rotate inside the shell 1 through the pulley 20. When the long pin 19 rotates, the connecting plate 25 and the second magnet 26 rotate synchronously. When the second magnet 26 approaches the first magnet 23, the protection frame 22 moves to a position away from the shell 1 under the action of the mutually repelling magnetic force. At this time, the upper connecting block 28 slides on the surface of the limit rod 27. At this time, the second spring 29 is squeezed, and When the second magnet 26 continues to rotate and moves away from the first magnet 23, the protection frame 22 moves back under the action of the second spring 29, and the above process is repeated. The protection frame 22 performs reciprocating linear motion in the horizontal direction under the action of the first magnet 23 and the second magnet 26, the limit rod 27 and the second spring 29. At this time, the protection frame 22 and the protection net 24 will be in a vibrating state under the action of the shell 1 and the second spring 29, and the dust on the protection net 24 will be shaken off, so that the protection frame 22 and the protection net 24 will not be blocked, and the protection net 24 can work normally without poor heat dissipation, thereby optimizing the heat dissipation and cooling effect of the shell 1.

[0063] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
