Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more features.

[0030] The maintenance box is a device for interfacing, testing and maintaining circuits. In the related art, the maintenance box includes a box door and a box body, the box door is installed on the box body and forms a mounting cavity accommodating electrical elements with the box body, and specifically, the electrical elements in the mounting cavity include two connected circuit breakers. However, in the above maintenance box, when the worker receives the notification of disconnecting the power, he may be mischarged due to other factors when the power is not disconnected or when the power is disconnected and the safety wear is not complete.

[0031] Therefore, the embodiment of the application provides a slot maintenance box, an insulating cover is arranged on the outside of the circuit breaker module, and the worker needs to open the insulating cover before each time of disconnecting the line, so as to perform the wiring or disconnecting operation, so as to avoid the mischarge phenomenon to a certain extent.

[0032] The embodiments of the application will be described in detail below with reference to the drawings and specific embodiments.

[0033] Please refer to Figures 1 to 3 ,Figure 1 A structural schematic view of the tank maintenance box provided by the embodiment of the present application is shown in the figure, Figure 2 A structural schematic view of the tank maintenance box provided by the embodiment of the present application is shown in the figure, Figure 3 A structural schematic view of the tank maintenance box provided by the embodiment of the present application is shown in the figure. As shown in the figure, the embodiment provides a tank maintenance box 10, which comprises a box door 1 and a box body 2. The box door 1 is installed on the box body 2 and encloses the box body 2 to form an installation cavity 3. A circuit breaker module 4 is arranged in the installation cavity 3. The tank maintenance box 10 further comprises an insulation cover 5 and two insulation pieces 6. The two insulation pieces 6 are arranged on opposite sides of the circuit breaker module 4. The top of the insulation cover 5 is rotationally connected with the two insulation pieces 6. The bottom of the insulation cover 5 extends below the circuit breaker module 4 and covers a terminal post (not shown in the figure) below the circuit breaker module 4. In the depth direction of the installation cavity 3, the size of the insulation cover 5 below the circuit breaker module 4 is smaller than the size of the circuit breaker module 4, so as to avoid the wire harness 8 connected to the terminal post.

[0034] In this way, by arranging the insulation pieces 6 and the insulation cover 5 and by covering the terminal post with the bottom structure of the insulation cover 5, the worker has to first uncover the insulation cover 5 before each time of wiring or unwiring, so as to perform the wiring or unwiring operation. The action of uncovering the insulation cover 5 reminds the worker to wear the labor protection articles in good order before performing the wiring or unwiring operation.

[0035] It should be noted that in the embodiment, a warning word “wear the labor protection articles in good order, and then turn off the power before testing the power” can be pasted on the insulation cover 5. In this way, the warning effect can be further achieved, so as to avoid the worker from being mistakenly electrocuted to a certain extent.

[0036] The insulation pieces 6 and the insulation cover 5 can be made of rubber or other insulating materials. In this regard, the material for making the insulation cover 5 and the insulation pieces 6 is not specifically limited.

[0037] Further, an installation plate 7 can be arranged on the cavity bottom wall of the installation cavity 3. The circuit breaker module 4 and other electrical components can be arranged on the installation plate 7. The insulation pieces 6 can also be connected with the installation plate 7. The connection manner between the insulation pieces 6 and the installation plate 7 can be adhesion or the like. In this regard, the connection manner between the insulation pieces 6 and the installation plate 7 is not specifically limited.

[0038] Generally, the circuit breaker module 4 comprises a first circuit breaker 41 and a second circuit breaker 42 connected together. One insulation piece 6 is arranged on the side of the first circuit breaker 41 away from the second circuit breaker 42. The other insulation piece 6 is arranged on the side of the second circuit breaker 42 away from the first circuit breaker 41.

[0039] The first circuit breaker 41 and the second circuit breaker 42 are arranged side by side along the horizontal direction.

[0040] It can be understood that the terminal blocks provided on any one of the first circuit breaker 41 or the second circuit breaker 42 can be multiple, and one terminal block corresponds to one wire harness 8. In this regard, the number of terminal blocks is not specifically limited.

[0041] Please refer to Figure 4 and Figure 5 , Figure 4 the structural schematic view of the insulating cover in the slot maintenance box provided by the embodiment of the present application, Figure 5 is Figure 4 the structural schematic view along the A direction. The insulating cover 5 comprises a first cover part 51 and a second cover part 52 connected together, the first cover part 51 is located on the side of the circuit breaker module 4 facing the cavity opening of the mounting cavity 3; the second cover part 52 is connected to the bottom of the first cover part 51 and is located below the circuit breaker module 4, and the second cover part 52 extends towards the cavity bottom wall of the mounting cavity 3; wherein the opposite sides of the first cover part 51 are respectively provided with a rotating shaft 53, and the two rotating shafts 53 are provided in one-to-one correspondence with the two insulating pieces 6, and the rotating shaft 53 is rotationally connected with the corresponding insulating piece 6. In this way, the rotational connection between the insulating cover 5 and the two insulating pieces 6 can be achieved.

[0042] Moreover, when the worker opens the insulating cover 5, it can be that the worker holds one end of the second cover part 52 close to the cavity bottom wall of the mounting cavity 3, then provides an upward force to open the insulating cover 5 upward, and then performs the wire disconnection operation, preventing the worker from being electrically shocked by mistake.

[0043] In order to reduce the manufacturing cost of the insulating cover 5 and avoid the first cover part 51 interfering with the wiring on the top of the circuit breaker module 4, as an optional embodiment, in the height direction, the size of the first cover part 51 is smaller than the size of the circuit breaker module 4.

[0044] In this way, not only the manufacturing cost of the insulating cover 5 is small, but also the wiring on the top of the circuit breaker module 4 will not be interfered by the first cover part 51, and the use performance of the insulating cover 5 is improved.

[0045] It should be noted that the height direction mentioned above is the up-down direction of the slot maintenance box 10 provided by the embodiment during use, please refer to the z-z axis direction in Figures 1 to 3 .

[0046] It can be understood that the insulating cover 5 can be manufactured in an integral molding manner, when the insulating cover 5 is an integral structure, in order to improve the manufacturing efficiency of the insulating cover 5, the extension direction of the first cover part 51 can be perpendicular to the extension direction of the second cover part 52. That is to say, in the embodiment, the first cover part 51 extends in the up-down direction, and the second cover part 52 extends in the front-rear direction.

[0047] The shape and forming method of the insulating cover 5 are not specifically limited herein.

[0048] Please refer to Figures 6 to 8 , Figure 6 A structure diagram of an insulating part in the tank maintenance box provided in the embodiment is shown in Figure 7 A structure diagram of an insulating part in the tank maintenance box provided in the embodiment is shown in Figure 6 A structure diagram of an insulating part in the tank maintenance box provided in the embodiment is shown in Figure 8 In some optional embodiments, a rotating hole 61 that is in rotating cooperation with the rotating shaft 53 is formed on each insulating part 6, so as to realize the rotating cooperation between the rotating shaft 53 and the insulating part 6. Through the rotating hole 61, the rotating shaft can extend into the rotating hole 61 and rotate with the rotating hole 61, which not only realizes the rotating cooperation between the rotating shaft 53 and the insulating part 6, but also limits the rotating shaft 53 to a certain extent, thereby avoiding the insulating cover 5 from falling off during use.

[0049] As shown in Figure 6 and Figure 7 , in a specific embodiment, the insulating part 6 includes a connecting plate 62 and two limiting plates 63, the two limiting plates 63 are arranged in a front-rear direction, and the connecting plate 62 is connected between the two limiting plates 63 to form an opening facing the circuit breaker module 4; the rotating hole 61 is arranged on one side of the connecting plate 62 facing the circuit breaker module 4.

[0050] In this embodiment, the insulating part 6 can also be an integral structure, which can improve the manufacturing efficiency of the insulating part 6 and further improve the assembly efficiency of the tank maintenance box 10 provided in the embodiment.

[0051] Further, in order to facilitate the rotating hole 61, the rotating hole 61 can penetrate the connecting plate 62. In this way, the manufacturing efficiency of the insulating part 6 can be further improved.

[0052] As shown in Figure 8 , in another embodiment, the rotating hole 61 penetrates the insulating part 6; the front side of the insulating part 6 has a notch 64 that is in communication with the rotating hole 61, and the width of the notch 64 is smaller than the diameter of the rotating hole 61. It should be noted that the width of the notch 64 is the size of the notch 64 in the up-down direction. In this way, the mass of the insulating part 6 can be reduced, and the assembly efficiency of the insulating part 6 can be improved. In addition, by limiting the size of the notch 64, the rotating shaft can be prevented from being pulled out of the rotating hole 61 to a certain extent, thereby improving the connection reliability between the insulating cover 5 and the insulating part 6.

[0053] It can be understood that when the work needs to be carried out, the staff is more anxious, in order to the smoothness of the insulating cover 5 when being opened, in some embodiments, the hole diameter of the rotating hole 61 is larger than the diameter of the rotating shaft 53. In this way, the phenomenon of jamming of the rotating shaft 53 during rotation can be avoided, and the convenience of the insulating cover 5 during use is improved.

[0054] Specifically, in the process of assembling the tank maintenance box 10 provided in the embodiment, an insulating part 6 is first assembled on the insulating cover 5, and another insulating part 6 is assembled on the insulating cover 5. When the assembly of the two insulating parts 6 and the insulating cover 5 is completed, the two insulating parts 6 are installed on the opposite sides of the circuit breaker module 4.

[0055] The same or similar reference numerals in the drawings of the embodiment correspond to the same or similar parts; in the description of the present application, it should be understood that if the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary illustration, and cannot be understood as a limitation of the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0056] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
