In addition, when positional terms such as both sides, outside, up and down are used, it should be understood that they are only used to facilitate understanding and description, considering that the structure may be facing other positions.

[0040] In the description of this application, unless otherwise clearly specified and limited, the technical or scientific terms used should have the usual meanings understood by persons with general skills in the field to which this application belongs. Terms such as "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection, or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] See also Figure 1 Or 2, the present invention provides a technical solution: a distribution box includes a shell 1, a guide rail 2, a movable part 3 and a mounting frame 4, the shell 1 has a storage space for accommodating electrical components 5, the shell 1 itself is a protective structure for electrical components 5 and can protect the electrical components 5 located in the storage space, and the shell 1 is provided with an opening at the bottom of the shell 1 that is connected to the storage space, and the electrical components 5 enter and exit the storage space through the opening. The guide rail 2 is vertically arranged, and the upper end of the guide rail 2 extends into the storage space through the opening. The movable part 3 is movably connected to the guide rail 2, and the guide rail 2 serves as the running track of the movable part 3, so that the movable part 3 can move up and down along the guide rail 2. The movable part 3 and the guide rail 2 can adopt the sliding cooperation mode of the slide rail slider. Of course, other methods known to those skilled in the art should also be within the protection scope. A locking part is provided on the movable part 3, and the locking part is at least used to lock the movable part 3 and the guide rail 2. The mounting frame 4 is at least used to install the electrical components 5 in a modular partitioning manner. Modular partitioning means that the installation areas of various types of electrical components 5 are demarcated on the mounting frame 4, and the respective cables take prescribed routes. The mounting frame 4 is connected to the movable part 3. After the mounting frame 4 and the movable part 3 are connected together, by pushing the mounting frame 4, the movable part can be moved upward along the guide rail 2, thereby driving the mounting frame 4 to move upward, and finally the mounting frame 4 enters the accommodating space.

[0042] Before using this device, it is necessary to first arrange various electrical components 5 in a modular manner on the mounting frame 4 and pre-install them on the mounting frame 4. The advantage of doing this is that there is no need to install the electrical components 5 one by one on site, and the operation is more convenient. At the same time, the pre-installation method of modular partitions can also effectively reduce the risk of incorrect cable line connection caused by operational errors during the installation process. After the electrical components 5 are installed, the device can be carried to the sea power base for specific installation operations. Since the electrical components 5 have been pre-installed on the mounting frame 4, many tools required for on-site installation are correspondingly reduced during the carrying process, which reduces the workload of the staff, and reduces the time for installing the electrical components 5 during the specific installation, so that the staff does not need to work outdoors for a long time, especially in harsh environments. The reduction in outdoor working time of the staff can reduce the risk of injury to the staff.

[0043] During the on-site installation process, first, the shell 1 is firmly fixed to the installation position of the distribution box of the sea power base by bolts (taking into account the influence of wind and waves at sea, the shell 1 is installed at a higher place, that is, the installation position has a certain height difference relative to the operating plane of the staff). Next, adjust the guide rail 2 to a vertical state, ensure that the upper end of the guide rail 2 extends into the accommodating space of the shell 1, and the lower end is in a position convenient for the staff to operate, and fix it to the sea power base with bolts. Subsequently, the external cables are connected one by one to the electrical components 5 pre-assembled on the mounting frame 4. This step is carried out in a position that is easy for the staff to operate, and the connection process is convenient. Importantly, the cable connection work is completed outside the shell 1, which effectively solves the technical problem of difficulty in cable connection due to the small internal space of the shell 1.

[0044] Afterwards, the mounting frame 4 is pushed to move upward, so that it can smoothly enter the accommodation space through the opening of the housing 1. Finally, the movable part and the guide rail 2 are locked by the locking part, so that the mounting frame 4 is firmly fixed in the accommodation space of the housing 1.

[0045] like Figure 4 As shown in Figure 5, in this embodiment: the mounting frame 4 has a long plate-like structure 6 with a rectangular ring cross section, and the two opposite surfaces of the long plate-like structure 6 in the thickness direction serve as two mounting surfaces of the mounting frame 4, and both mounting surfaces are designed to install various types of electrical components 5. Specifically, the installation areas of different electrical components 5 are planned on the two mounting surfaces, so as to realize the modular partition installation of the electrical components 5. The mounting frame 4 adopts a long plate-like design with a rectangular ring cross section, so that a space for accommodating cables is formed between the two mounting surfaces. Such a design not only effectively utilizes space resources, but also can hide the cables in the space, making the overall layout more neat and orderly. In addition, the two relatively arranged mounting surfaces can install more electrical components 5 in a limited space, which is particularly suitable for the case where there are a large number of electrical components 5 on the sea power base. At the same time, the electrical components 5 on the two mounting surfaces are separated by this space, so that the space naturally becomes a heat dissipation channel for the electrical components 5, which is conducive to the effective heat dissipation of the electrical components 5.

[0046] like Figure 2 Or as shown in 3, in this embodiment: the locking part includes a U-shaped rod 7, the U-shaped rod 7 includes a transverse part and two vertical parts, one end of the two vertical parts is hinged to the opposite sides of the movable part 3, so that the U-shaped rod 7 can rotate relatively along the movable part, and a slot 8 is provided on the guide rail 2. During the rotation of the U-shaped rod, the transverse part of the U-shaped rod 7 can be inserted into the slot 8 to fix the position of the movable part on the guide rail 2, and when the transverse part of the U-shaped rod 7 is inserted into the slot 8, the mounting frame 4 is located inside the shell 1, and the fixing of the position of the movable part further fixes the mounting frame 4 inside the shell 1.

[0047] like Figure 3 As shown, in this embodiment: an elastic structure is provided on the movable part 3, through which the transverse part of the U-shaped rod 7 can be pressed against the surface of the guide rail 2, and then when the transverse part of the U-shaped rod 7 slides to the position of the slot 8, it can be automatically snapped into the slot 8 under the elastic force of the elastic structure. Through the above arrangement, the step of manually rotating the U-shaped rod 7 to snap the transverse part into the slot 8 is omitted, and the mounting frame 4 only needs to be pushed to a predetermined position in the housing 1, and the transverse part of the U-shaped rod 7 can be automatically snapped into the slot 8 under the drive of the elastic structure, and the operation process is more convenient.

[0048] Furthermore, the hinged end of the vertical portion of the U-shaped rod 7 and the movable portion 3 extends in a direction away from the horizontal portion of the U-shaped rod 7 to form a toggle portion 14. The U-shaped rod 7 can be rotated by toggling the toggle portion 14. The elastic structure is an elastic paddle 9, one end of which serves as a connecting end and is fixedly connected to the movable portion by welding or bolting, and the other end serves as a movable end and contacts with the toggle portion 14. When the horizontal portion of the U-shaped rod 7 moves from the inside of the slot 8 to the direction of leaving the slot 8, the toggle portion 14 will push the movable end of the elastic paddle 9 to displace and cause the elastic paddle 9 to be elastically stressed. Subsequently, when the horizontal portion of the U-shaped rod 7 reaches the end of the slot 8, under the elastic force of the elastic paddle 9, the horizontal portion of the U-shaped rod 7 can automatically fit into the slot 8.

[0049] It should be noted that, in addition to the elastic paddle 9, the elastic structure may also be a spring, an elastic rope, or other elastic structures well known to those skilled in the art.

[0050] Furthermore, the slot 8 is opened on the top surface of the guide rail 2, and first extends along the thickness direction of the guide rail 2, and then the lower end continues to extend downward along the length direction of the guide rail 2, and the left and right sides of the guide rail 2 respectively penetrate the outside of the guide rail 2, forming a socket with an L-shaped cross-section as a whole. By inserting the transverse part of the U-shaped rod 7 into the socket, the mounting frame 4 can be effectively fixed to the inside of the shell 1, and the rotation of the U-shaped rod 7 can be limited, thereby reducing the fixation failure caused by the arbitrary rotation of the U-shaped rod 7.

[0051] Furthermore, the upper end of the slot 8 has a first inclined surface 10, and the upper end of the first inclined surface 10 is inclined toward the top of the guide rail 2. Through the first inclined surface 10, when the lateral portion of the U-shaped rod 7 is located in the slot 8 and pushes the mounting frame 4 upward, the lateral portion of the U-shaped rod 7 can slide upward along the first inclined surface 10, so that it gradually moves from the depth of the slot 8 to the outside until the lateral portion of the U-shaped rod 7 is disengaged from the slot 8, reducing the step of manually rotating the U-shaped rod 7 to disengage its lateral portion from the slot 8, and the operation is simpler.

[0052] like Figure 2As shown in Figure 6, in this embodiment: the movable part 3 is connected to a cover plate 11 for closing the opening of the housing 1. Through the cover plate 11, after the movable part 3 and the mounting frame 4 carried by it are pushed into the housing 1 and fixed, the opening of the housing 1 can be covered, so that the electrical components 5 in the housing space of the housing 1 can be better protected, thereby improving the safety and stability of the entire device.

[0053] In this embodiment: an unlocking portion is movably provided on the cover plate 11, and the unlocking portion is a pry bar 12 that penetrates the cover plate 11 along the thickness direction of the cover plate 11, and the pry bar 12 is slidably connected to the cover plate 11. The end of the pry bar 12 close to the mounting frame 4 is a pushing end for pushing the U-shaped rod 7 to rotate, and the end away from the mounting frame 4 is used as an operating end. By toggling the operating end of the pry bar 12, the pushing end of the pry bar 12 is displaced. As the pushing end moves, it contacts the U-shaped rod 7 and applies a rotational torque, causing the U-shaped rod 7 to rotate, and finally causing the transverse portion of the U-shaped rod 7 to disengage from the slot 8, thereby releasing the mounting frame 4 from a fixed state in the shell 1.

[0054] like Figure 7 As shown in Fig. 8, in other embodiments: a through hole 13 is provided on the cover plate 11 for the U-shaped rod 7 to pass through, and the U-shaped rod 7 can rotate in the through hole 13. When the U-shaped rod 7 passes through the through hole 13, the flexibility of rotation can still be maintained. In addition, a part of the U-shaped rod 7 will extend out of the cover plate 11, so that the staff can directly contact and operate this part of the U-shaped rod 7. When it is necessary to release the fixing of the mounting frame 4 in the housing 1, the staff can rotate the lateral part of the U-shaped rod 7 by shifting or rotating the part of the U-shaped rod 7 extending out of the cover plate 11. As the lateral part of the U-shaped rod 7 rotates, it will gradually slide out of the slot 8, thereby realizing the unlocking of the mounting frame 4 in the housing 1.

[0055] In this embodiment: the mounting frame 4 is detachably connected to the movable part 3. When the space is narrow and it is inconvenient to connect the cables to the electrical components 5 on the mounting frame 4, the mounting frame 4 and the movable part 3 can be disassembled first, and a place convenient for connecting the cables can be found. After the cables are successfully connected, the mounting frame 4 and the movable part 3 can be connected together, so that the operation is more convenient. Specifically, the detachable connection between the mounting frame 4 and the movable part 3 can be achieved by bolt fixing, snap connection, hook connection, etc.

[0056] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, some simple deductions or substitutions can be made without departing from the concept of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
