Description

Technical Field

[0001] The utility model relates to the technical field of offshore electrical equipment, in particular to an inspection door device for an offshore module electrical station. Background Art

[0002] As a clean energy, wind power has developed rapidly at home and abroad. At present, most offshore wind power booster stations adopt overall construction technology, which is relatively costly. In order to significantly reduce the construction cost of wind power, the use of modular structure is the main direction of reducing costs. First, electrical equipment is installed on land using a compact container shell, and then the entire station is built and transported to the sea for installation. Due to the use of modular structure technology, the internal space of the container shell is relatively narrow, and there is insufficient space for workers during construction and maintenance. Therefore, it is necessary to open door openings in the shell and then install corresponding door panels. When construction and maintenance are required, the door panels can be opened and the walkway outside the container shell can be used to increase the construction and maintenance space for workers.

[0003] In order to prevent moisture and dust from entering the interior of the shell, the traditional inspection door device needs to be equipped with relatively tight seals on the door panel to ensure the sealing performance inside the shell. However, this also means that it is more difficult to open the door panel. Therefore, it is necessary to install a power-assisting device on the door panel. The traditional power-assisting device is large in size, which causes certain obstacles to the conventional door opening and closing operations, and also takes up the space for placing electrical equipment.

[0028] like Figure 1-3 As shown, according to an embodiment of the first aspect of the utility model, an inspection door device of an offshore module electrical station includes a shell 100, a door panel 200, a sealing assembly 300 and a power-assisting assembly 400. The shell 100 is provided with a door opening 110. The door panel 200 is rotatably arranged on the shell 100 so as to be able to open or close the door opening 110. The sealing assembly 300 is arranged between the inner wall of the door opening 110 and the outer wall of the door panel 200. The power-assisting assembly 400 includes a support 410, a support rod 430 and a power-assisting rod 440. The support rod 430 is rotatably connected to the shell 100, the head end of the support rod 430 is detachably connected to the door panel 200, and the tail end of the support rod 430 is detachably connected to the power-assisting rod 440.

[0029] Among them, the inspection door device can be applied to an offshore modular electrical station. In the offshore modular electrical station, the shell 100 can be a container shell 100, in which electrical equipment such as circuit breakers and transformers are placed. A plurality of door openings 110 can be opened on the shell 100, and each door opening 110 is correspondingly installed with a door panel 200. The power assist assembly 400 is usually installed on the inner side of the shell 100. It should be noted that the shell 100 is usually also provided with an access door, which facilitates the staff to enter and exit the shell 100, and then open the door panel 200 of each inspection door device from the shell 100.

[0030] In the maintenance door device of the offshore modular electrical station of the present invention, a sealing assembly 300 is arranged between the inner wall of the door opening 110 and the outer wall of the door panel 200, so as to ensure the sealing performance of the environment inside the shell 100, so that water vapor and dust are not easy to enter the shell 100. When the staff needs to repair the equipment inside the shell 100, the power rod 440 can be installed on the support rod 430. By utilizing the principle of lever, the force arm of the force is extended, and the position where the support rod 430 is rotatably connected to the shell 100 is used as the fulcrum. The head end of the support rod 430 is pressed against the door body to open the door body. After the door body is opened, the head end of the support rod 430 can be separated from the door panel 200, so as not to hinder the normal opening and closing operation of the door panel 200. At the same time, after the maintenance is completed, the staff can also remove the power rod 440 from the support rod 430, which will not hinder the operation of the equipment inside the shell 100. The present design is convenient for power-assisted opening of the door panel 200, has a compact structure, and saves space.

[0031] In some embodiments of the present invention, the sealing assembly 300 includes a first sealing strip 310 and a second sealing strip 320, wherein the first sealing strip 310 is extended along the inner wall of the door opening 110, and the second sealing strip 320 is extended along the outer wall of the door panel 200, and the first sealing strip 310 and the second sealing strip 320 can press against each other.

[0032] Both the first sealing strip 310 and the second sealing strip 320 can be made of rubber or resin materials. When the door panel 200 is closed in the door opening 110, the first sealing strip 310 and the second sealing strip 320 will press against each other and deform to ensure the sealing performance. At the same time, there is a large friction force between the first sealing strip 310 and the second sealing strip 320, so the power assist component 400 is required to apply force to the door panel 200 to facilitate the opening of the door panel 200.
