Description

Technical Field

[0001] The utility model relates to the technical field of electrochemical energy storage cabinets, in particular to an energy storage cabinet capable of preventing a cabinet door from self-rotating. Background Art

[0002] Electrochemical energy storage cabinets are generally installed outdoors. During installation, commissioning, testing and maintenance, the cabinet door is prone to rotate and close automatically after opening due to its own center of gravity offset and external wind pressure, which is very likely to cause safety problems. Therefore, a device is needed that can lock the cabinet door in a predetermined position when it is opened, and release the lock when the cabinet door needs to be closed.

[0003] In the prior art, such as patent application No. 201822208097.1 “A foldable box-type substation limit wind brace” discloses “a first limit plate rotatably fixed on the door panel of the box-type substation, a second limit plate rotatably fixed on the frame of the box-type substation, the first limit plate and the second limit plate are rotatably connected, a limit pin is provided on the top of the second limit plate, a limit groove is provided on the first limit plate, and the limit pin enters the groove to lock the door panel”. To unlock this structure, force must be applied outward from the inside of the first limit plate and the second limit plate, and the space for applying force is limited. For example, patent application number 202220400500.4 "A door panel limit device and a distribution box cabinet" discloses "a first limit plate, a second limit plate and a limit rod, the first limit plate is provided with a first limit hole, the second limit plate is provided with a second limit hole, one end of the limit rod is movably connected to the second limit plate, and the other end is matched with the first limit hole or the second limit hole". This structure requires the limit rod to be inserted into the limit hole when it reaches the limit position when opening the door, and the limit rod needs to be lifted when closing the door. The operation is inconvenient, which invisibly increases the labor of the staff, and the limit rod is easy to fall off. Utility Model Content

[0028] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] Embodiment 1

[0030] like Figure 1As shown in the figure, the present utility model provides an energy storage cabinet that prevents the cabinet door from automatically rotating back, including: a cabinet body, a cabinet door, and an anti-cabinet door automatic rotation device arranged between the cabinet body and the cabinet door. The cabinet door and the cabinet body are connected by a door hinge. The anti-cabinet door automatic rotation device includes a first connecting rod 2, a second connecting rod 4, and a support 6. The cabinet body, the first connecting rod 2, the second connecting rod 4, and the cabinet door together form a double rocker mechanism. Among them, the first end of the first connecting rod 2 is rotatably connected to the bottom plate of the cabinet body, the second end of the first connecting rod 2 is rotatably connected to the first end of the second connecting rod 4, the second end of the second connecting rod 4 is rotatably connected to the support 6, and the support 6 is fixedly installed on the inner side of the cabinet door.

[0031] The anti-cabinet door automatic rotation device further includes a first rotating shaft 1, a second rotating shaft 3, and a third rotating shaft 5. And there is an opening on the bottom plate of the cabinet body. Among them, the bottom end of the first rotating shaft 1 is inserted into the opening of the cabinet body bottom plate and fixed by welding. Installation holes are provided at both ends of the first connecting rod 2, the second connecting rod 4, and the support 6. The first end of the first connecting rod 2 is sleeved on the first rotating shaft 1 through the installation hole, and the two are in clearance fit, so that the first connecting rod 2 can rotate around the first rotating shaft; after the installation hole at the second end of the first connecting rod 2 is aligned with the installation hole at the first end of the second connecting rod 4, they are sleeved on the second rotating shaft 3. Specifically: both the first connecting rod 2 and the second connecting rod 4 are set as "C"-shaped structures, and the width of the first connecting rod is greater than the width of the second connecting rod. When the installation hole at the second end of the first connecting rod 2 is aligned with the installation hole at the first end of the second connecting rod 4, the first end of the second connecting rod is embedded in the second end of the first connecting rod, so that the first end of the second connecting rod can rotate around the second rotating shaft within the first connecting rod, and the second rotating shaft is in clearance fit with both the first connecting rod and the second connecting rod; after the installation hole at the second end of the second connecting rod 4 is aligned with the installation hole on the support 6, they are sleeved on the third rotating shaft 5. Similarly, there is also a clearance fit between the second connecting rod and the third rotating shaft.

[0032] In this embodiment, the support is set as an L-shaped structure, and the installation hole on the support is arranged on the horizontal plane, and the vertical surface of the support is welded to the bottom of the inner side of the cabinet door.

[0033] The working principle of the anti-cabinet door automatic rotation device in this embodiment is as follows:

[0034] As Figure 3 shown, when the cabinet door is opened, the cabinet door drives the support 6 and the third rotating shaft 5 to rotate around the door hinge, the second connecting rod 4 rotates around the third rotating shaft, and at the same time moves horizontally along with the third rotating shaft. The first connecting rod 2 rotates around the first rotating shaft. When the first rotating shaft, the second rotating shaft, the third rotating shaft, the first connecting rod, and the second connecting rod are on the same straight line, the torque on the first connecting rod and the second connecting rod is zero. At this time, the double rocker mechanism is in the dead point position, and the cabinet door is in the locked state. As Figure 2As shown, when the cabinet door needs to be closed, an inward external force is applied at the second rotation axis, which can be understood as kicking inward at the second rotation axis with the foot to contact the dead point state, and the cabinet door can be easily closed. During the entire closing process, the first connecting rod and the second connecting rod will not interfere with the cabinet door and the components inside the cabinet body.

[0035] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may 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.
