[0038] like Figures 1 to 5 As shown, an embodiment of the utility model provides a protective door, which includes a door frame 10, a first door body 21 and a first locking structure 31. The first door body 21 is movably arranged on the door frame 10 along the vertical direction, and a first buffer structure is provided between the door frame 10 and the first door body 21, and the first buffer structure is used to buffer the fall of the first door body 21. The first locking structure 31 has a first locking state and a first opening state that are relatively arranged. When the first locking structure 31 is in the first locking state, the first locking structure 31 can fix the position of the first door body 21 relative to the door frame 10. Figure 2 As shown, the Y direction is the length direction of the first door body 21, and the Z direction is the vertical direction. Specifically, in the present application, the first door body 21 has a first blocking position and a first opening position that are relatively arranged. When the first locking structure 31 is in the first locking state, the first door body 21 is in the first blocking position, and the first door body 21 can block the door frame 10.

[0039] By applying the technical solution of the present application, the first door body 21 is movably arranged on the door frame 10 in the vertical direction. When the staff performs installation, debugging and other operations on the inside of the medium-voltage integrated machine, they only need to push and pull the first door body 21, so that the staff can enter the inside of the medium-voltage integrated machine for operation without removing the protective door, which is convenient for the staff to operate the inside of the medium-voltage integrated machine through the protective door, reducing the work difficulty and labor cost of the staff.

In addition, the staff can fix the first door body 21 through the first locking structure 31 to prevent the first door body 21 from shaking when it does not need to be moved and affecting the maintenance of the staff. At the same time, it can prevent the first door body 21 from falling quickly and causing harm to the staff, ensuring the safety of the staff. At the same time, it can avoid a large collision between the first door body 21 and the ground, thereby improving the service life of the first door body 21.

[0040] like Figure 2 and Figure 3 As shown, the protective door further includes a first guide structure 41, which is disposed between the first door body 21 and the door frame 10, and can guide the first door body 21, and a first buffer structure is disposed between the first guide structure 41 and the first door body 21. Such an arrangement can ensure the stability and accuracy of the staff when moving the protective door, and prevent the first door body 21 from tilting during the movement.

[0041] like Figure 3As shown, the first guide structure 41 includes a first slide rail 411 and a first guide member 412.

The other end of the first guide member 412 is movably arranged on the first slide rail 411. The first buffer structure is arranged between the first slide rail 411 and the first door body 21. Such an arrangement has a simple structure, and is convenient for installing and fixing the first guide structure 41. At the same time, it can reduce the space occupied by the first guide structure 41, and further improve the space utilization rate of the medium-voltage integrated machine. Among them, the first slide rail 411 is connected to the door frame 10 by a plurality of third bolts.

The first guide structure 41 may include a plurality of first guide members 412, and the plurality of first guide members 412 are arranged at intervals along the vertical direction.

[0044] Among them, a first counterweight 51 is provided on one side of the length direction of the first door body 21, and a protrusion is provided on the side wall of the first slide groove 4111. The protrusion and the first counterweight 51 cooperate to form a first buffer structure, and the protrusion cooperates with the first guide member 412 to buffer the first door body 21. In this way, the first counterweight 51 can make the first door body 21 slightly tilted during the falling process, so that the first guide member 412 is tilted, and then the first guide member 412 contacts the protrusion, so that the first guide member 412 can be fixed, and then the first door body 21 can be fixed. The structure is simple, and it is convenient to process the first door body 21 and the first slide groove 4111.

[0045] Specifically, in the present application, a first protrusion 4112 is provided on one side of the first slide groove 4111, and a second protrusion 4113 is provided on the other side of the first slide groove 4111.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0069] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0070] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0071] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0072] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
