Description

Technical Field

[0001] The invention relates to the technical field of electrical control, and in particular to an intelligent grounding switch device for an offshore wind farm. Background Art

[0002] In offshore wind farms, the corrosion resistance of electrical equipment is particularly important because the equipment is exposed to harsh marine environments such as high humidity and high salt spray for a long time. However, the widely used grounding switchgear is prone to corrosion in such an environment. Corrosion not only causes the conductivity of the equipment to decrease, but also shortens the service life of the equipment. Frequent equipment replacement and maintenance significantly increase the operating costs of wind farms and bring heavy burdens to enterprises. In addition, traditional grounding switchgear has many inconveniences in design, especially in the installation and maintenance of static and moving contacts. Due to the complex structural design, the disassembly and cleaning process of the contacts is cumbersome and requires a lot of time and effort.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Reference Figure 1 to Figure 10This embodiment provides an intelligent grounding switch device for an offshore wind farm, including a protection module 100, an installation module 200 and a conductive module 300, wherein the conductive module 300 is installed on the installation module 200, and the installation module 200 is movably connected in the protection module 100 as a whole, and the installation module 200 can be slid and adjusted in the protection module 100 to facilitate the installation, adjustment and maintenance of the conductive module 300. When the conductive module 300 needs to be repaired or replaced, the installation module 200 can be easily slid out of the protection module 100, thereby greatly improving the maintenance efficiency and operation convenience of the equipment. At the same time, the effect of the protection module 100 is to provide reliable external protection for the equipment, especially in the harsh environment of the offshore wind farm, the protection module 100 can effectively resist the erosion of high humidity, high salt fog and other corrosive factors on the internal components.

[0035] Specifically, the protection module 100 includes a first protective shell 101 and a second protective shell 102. A first installation cavity 101a is opened inside the first protective shell 101, and a second installation cavity 102a is opened inside the second protective shell 102. The first protective shell 101 is arranged at the front end of the second protective shell 102, and is fixed to each other by a card slot 101b and a card plate 102b. The first protective shell 101 and the second protective shell 102 are both made of stainless steel material, have excellent mechanical strength, and can withstand the mechanical stress, vibration and external impact generated by the equipment during operation, and the inner surface thereof is coated with a corrosion-resistant insulating coating, which can provide effective protection in a marine environment with high humidity and high salt fog, ensuring long-term and reliable operation of the equipment.

[0036] Through this structural design, the main conductive components in the conductive module 300, such as the moving contact 304, the static contact 305, the soft wire 302, etc., are completely protected in the protective shell, effectively preventing the corrosive elements in the marine environment from directly corroding these key components, thereby extending the service life of the equipment and ensuring the stability and safety of the conductive module. At the same time, insulating materials are used to isolate the first protective shell 101 and the second protective shell 102 and the key conductive components to prevent short circuits or other electrical failures, thereby ensuring the long-term stable operation of the entire grounding switch equipment.

[0037] It is important to note that in some cases, the surface of a metal enclosure may be coated with an insulating coating, especially when it is necessary to prevent accidental contact or meet specific safety standards. However, this coating is not intended to completely insulate the enclosure, but rather to provide additional safety protection.

[0038] More specifically, the mounting module 200 includes a first fixing plate 201 slidably connected to the bottom of the first mounting cavity 101a and a second fixing plate 202 slidably connected to the bottom of the second mounting cavity 102a. Side baffles 203 are symmetrically installed on the left and right sides of the first fixing plate 201. The side baffles 203 play a role in supporting and stabilizing the entire mounting module 200 to ensure that it slides smoothly in the first mounting cavity 101a. A rotating rod 204 is arranged between the two side baffles 203. The rotating rod 204 is used to transmit the operating force to realize the rotation of the toggle rod 205. The rear end of the rotating rod 204 is fixedly installed with a toggle rod 205. The toggle rod 205 is used to control the movement of the movable block 206, thereby driving the conductive module 300. The moving contact 304 and the stationary contact 305 are engaged or separated, and the rear end of the toggle rod 205 is hinged with a movable block 206, and the movable block 206 is connected to the toggle rod 205 by a hinged manner, so that it can flexibly adjust its position, and a mounting frame 207 is arranged on the periphery of the movable block 206, and the mounting frame 207 is used to fix and support the relevant components of the conductive module 300 to ensure that it is firmly installed on the movable block 206, and an insulating column 208 is fixedly installed on the top of the second fixed plate 202. The insulating column 208 plays a role of electrical isolation to prevent electrical short circuits between conductive components, and at the same time provides a stable support structure for the conductive module 300 to ensure that the entire system maintains good electrical performance and mechanical stability during operation.

[0039] More specifically, the conductive module 300 includes a grounding terminal 301 fixedly mounted on the outer bottom wall of the first protective shell 101. The grounding terminal 301 is used to ground the equipment to ensure that the system can quickly conduct the fault current when a fault occurs to protect the safety of the equipment and personnel. A soft wire 302 is plugged into the top of the grounding terminal 301. The soft wire 302 has good flexibility and conductivity and is used to connect the grounding terminal with the internal conductive components to ensure smooth conduction of the current. The other end of the soft wire 302 is conductively connected to a metal connecting piece 303. The metal connecting piece 303 is made of a highly conductive material and is used to conduct the current from the soft wire to the moving contact 304. The bottom end of the moving contact 304 is plugged into the metal connecting piece 303. On the sheet 303, the moving contact 304 is movably installed in the conductive module 300, and can contact with the static contact 305 when needed to complete the connection of the electrical circuit. The static contact 305 is suspended directly above the moving contact 304, and the static contact 305 is fixedly installed on the connecting guide plate 306. It is responsible for engaging or disengaging with the moving contact 304 to control the on and off of the circuit. The top of the static contact 305 is fixedly connected with the connecting guide plate 306, and the connecting guide plate 306 is fixedly installed on the upper surface of the insulating column 208 by bolts to ensure the structural stability of the conductive module 300. At the same time, the combined design of the connecting guide plate 306 and the insulating column 208 provides good electrical isolation to prevent short circuits or other electrical faults in the circuit.

[0040] Through the above design, the various components of the conductive module 300 not only achieve reliable electrical connection, but also ensure good electrical insulation and mechanical stability. In addition, the combination of the conductive module 300, the protective module 100 and the installation module 200 makes the entire system have excellent corrosion resistance and easy maintenance in the marine environment. The protective module 100 provides a solid external protection for the conductive module 300 to prevent the external environment from corroding the electrical components, and the slidable design of the installation module 200 makes the conductive module 300 more convenient during installation and maintenance, and can be quickly disassembled and repaired. This structural design not only improves the safety and reliability of the equipment, but also significantly improves the operating efficiency and maintenance convenience, and is suitable for long-term application in harsh environments such as offshore wind farms.

[0041] Furthermore, openings 103 are provided on opposite surfaces of the top ends of the first protective shell 101 and the second protective shell 102, and the openings 103 are connected to the first installation cavity 101a and the second installation cavity 102a. This design allows the installation module 200 and the related components of the conductive module 300 to be connected and operated through the openings 103, while ensuring the connectivity of the internal space and the integrity of the structure. Slide grooves 101c are symmetrically provided on the left and right sides of the rear end of the first protective shell 101. The slide grooves 101c are used for the sliding connection of the side baffle plate 203, so that the installation module 200 can move smoothly in the first installation cavity 101a. The guide plate 306 is sealed at the opening 103. The design purpose is to completely close the opening 103 to prevent corrosive elements such as moisture and salt spray in the external environment from entering the interior of the protective shell, thereby ensuring the long-term stable operation of the internal components.

[0042] The upper surface of the connecting guide plate 306 is exposed to the outside of the first protective shell 101 and the second protective shell 102. This design ensures that external electrical equipment can be directly connected to the key components of the conductive module 300 (such as the static contact 305), thereby realizing the electrical path between the equipment and the external circuit. Since the connecting guide plate 306 is completely sealed at the opening 103, the conductive components below it are effectively protected to prevent the external environment from invading the internal components. In addition, the two side baffles 203 are slidably connected in the slide groove 101c. The design of the side baffles 203 can effectively seal the slide groove 101c to prevent the slide groove from becoming a channel for environmental corrosion, while maintaining the structural integrity of the first protective shell 101 and the second protective shell 102. Through this sealing design, a complete closed system is formed between the first protective shell 101 and the second protective shell 102 and the connecting guide plate 306 and the side baffles 203, ensuring the airtightness and corrosion resistance of the internal components, so that the entire equipment can operate reliably for a long time in the harsh environment of the offshore wind farm.

[0043] This design not only improves the protection performance of the equipment, but also ensures the safe connection between external electrical equipment and the conductive module 300, while providing a convenient maintenance and operation channel, greatly improving the durability and maintenance efficiency of the equipment.

[0044] Furthermore, the design of the mounting frame 207 includes a plurality of components that cooperate with each other to achieve precise operation and stable connection of the conductive module 300. The mounting frame 207 first includes two support plates 207a fixedly mounted on the top of the first fixed plate 201. The support plates 207a play a supporting and positioning role to ensure that the movable block 206 can remain stable during operation. Limiting plates 207b are fixedly mounted on the tops of the two support plates 207a. The limiting plates 207b are used to limit the moving range of the movable block 206 to prevent it from excessive movement or separation from the supporting structure during operation. A limiting rod 207c is arranged on the inner side of the support plate 207a. The limiting rod 207c is slidably connected to the movable block 206, providing a sliding path for the movable block 206 so that it can move smoothly in the vertical direction.

[0045] In order to realize the control of the movable block 206, the left and right ends of the rotating rod 204 are rotatably connected to the inner walls of the two side baffles 203 through the rotating shaft 209. This design enables the rotating rod 204 to rotate flexibly in the side baffle 203. The left end of the left rotating shaft 209 is fixedly connected with a handle 210. The handle 210 is arranged outside the protective shell to facilitate the staff to grasp and manipulate during operation. When the staff grasps the handle 210 and rotates it forward, the rotating shaft 209 will drive the rotating rod 204 to rotate forward. When the rotating rod 204 rotates, the rotational motion can be converted into linear movement of the movable block 206 through the toggle rod 205 fixedly connected thereto. While rotating, the movable block 206 moves vertically upward along the limit rod 207c. As the movable block 206 moves upward, the moving contact 304 also moves vertically upward. When the top of the moving contact 304 is inserted into the slot of the static contact 305, the circuit can be connected. Conversely, when the staff rotates the handle 210 backward, the rotating shaft 209 will drive the rotating rod 204 to rotate in the opposite direction. The reverse rotation of the rotating rod 204 will cause the movable block 206 to move vertically downward along the limit rod 207c through the toggle rod 205. As the movable block 206 moves downward, the moving contact 304 also moves vertically downward, gradually disengaging from the slot of the static contact 305, thereby disconnecting the circuit.

[0046] This design ensures safe control of the circuit and reliable operation. The operator can easily connect and disconnect the circuit by simply turning the handle 210 forward and backward. This design not only improves the convenience of operation, but also effectively reduces the risk of misoperation, while ensuring safety in harsh environments such as offshore wind farms and long-term stable operation of the equipment.

[0047] Furthermore, a first slot 206a and a second slot 206b are respectively provided at the front and rear ends of the upper surface of the movable block 206. Such a design enables different components to be fixed on the movable block for easy disassembly and replacement. A fixing slot 206c is respectively provided at the bottom ends of the first slot 206a and the second slot 206b for stably fixing the metal connecting plate 303 and related components. The metal connecting plate 303 is fixedly installed in the fixing slot 206c to ensure that its conductive connection with the moving contact 304 is reliable and stable. One end of the soft wire 302 is movably inserted into the second slot 206b. A hand grip slot 202a is provided at the front end of the second fixed plate 202, which provides an operator with a convenient gripping position for pulling out or inserting the second fixed plate 202 and the components thereon.

[0048] When the staff needs to perform maintenance, they can first break the first protective shell 101 and the second protective shell 102 apart, and pull out the second fixing plate 202 together with the insulating column 208, the connecting guide plate 306 and the static contact 305 from the second protective shell 102 through the buckle groove 202a. Then, the staff can use a wrench or other tools to remove the connecting guide plate 306 and the static contact 305 from the insulating column 208 for separate inspection, cleaning or replacement. Next, the staff can handle the soft wire 302 and connect it to the ground terminal. One end of the connection 301 is pulled out from the bottom of the first protective shell 101 to complete the disconnection from the external device. Subsequently, the first fixed plate 201 can also be pulled out from the first protective shell 101 in a similar manner to expose other internal components. At this time, the staff can pull out the other end of the soft wire 302 from the second slot 206b, easily remove the soft wire 302, and complete the disconnection of the relevant electrical connection parts. Finally, the moving contact 304 can also be pulled out from the first slot 206a, thereby realizing the disassembly of the moving contact 304.

[0049] This design ensures the stability of each component during installation, and also greatly facilitates maintenance and replacement operations. Through reasonable structural design, the maintenance process of the equipment becomes simpler and faster, reducing downtime and improving the efficiency and reliability of overall operation. This modular design allows operators to quickly and safely disassemble and replace key components, ensuring the long-term stable operation of the equipment in harsh environments such as offshore wind farms.
