[0014] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", and "right" indicating directions or positional relationships, they are only corresponding to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0015] See also Figure 1-3 , the utility model provides the following technical solutions:

[0016] Example 1: An online monitoring device for batteries in an energy storage power station includes a battery case 1 and a monitoring body 2, the monitoring body 2 being connected to the battery case 1 via a connector 3; the connector 3 includes a connecting post 3.3, one end of which is provided with an end plate 3.1, the connecting post 3.3 passing through a through hole in a side panel of the monitoring body 2, and the column body of the connecting post 3.3 being provided with a positioning post 3.31; the side panel of the battery case 1 is provided with a through hole 1.1 for the connecting post 3.3 to pass through, the through hole 1.1 also being provided with a through slot 1.11 for the positioning post 3.31 to pass through, and the side of the battery case 1 facing away from the monitoring body 2 is also provided with an arcuate slide 1.2, the arcuate slide 1.2 being provided with a positioning slot 1.22 adapted to the positioning post 3.31;

[0017] It can be understood that the connecting column 3.3 is passed through the through hole on the side plate of the monitoring body 2 and the through hole 1.1 on the side plate of the battery box 1, and the positioning column 3.31 is passed through the through slot 1.11. Then, the connecting column 3.3 is twisted and rotated, and the positioning column 3.31 slides on the arc slide 1.2. Then, the connecting column 3.3 will produce axial movement, so that the end plate and the side plate of the monitoring body 2 come into contact. Then, the positioning column 3.31 enters the positioning slot 1.22, preventing the positioning column 3.31 from slipping, thereby enabling the monitoring body 2 and the battery box 1 to be quickly fixed, solving the disadvantage of the traditional method of fastening with bolts or direct welding that is inconvenient to disassemble;

[0018] Example 2: Different from Example 1, the column body of the connecting column 3.3 is sleeved with a spring 3.2, and the two ends of the spring 3.2 respectively contact the end plate 3.1 and the side plate of the monitoring body 2; the arc slide 1.2 is coaxial with the through hole 1.1, and the arc slide 1.2 is provided with an inclined surface 1.21, and the bottom end of the inclined surface 1.21 corresponds to the side plate of the battery box 1 and faces the through groove 1.11; the spring 3.2 is used, that is, when separating the battery box 1 and the monitoring body 2, the connecting column 3.3 is slightly rotated to disengage the positioning column 3.31 from the positioning groove 1.22, and then the positioning column 3.31 automatically moves along the inclined surface 1.21 under the action of the spring 3.2, and then the positioning column 3.31 enters the through groove 1.11, which facilitates the automatic completion of the separation operation, which is simple and practical.

[0019] Example 3: Unlike Example 1, the connecting column 3.3 is a tubular structure, through which the lines can pass. That is, the signal lines of some sensors in the battery box 1 can pass through the through hole in the middle of the connecting column 3.3, thereby using it as a threading tube, which is convenient to use. The end plate 3.1 is a flange plate, and at least one slot 3.11 is provided on the edge of the end plate 3.1 to facilitate hand-held rotation of the end plate 3.1.

[0020] In addition, the through holes on the side panels of the monitoring body 2 and the through holes 1.1 are both clearance-matched with the connecting posts 3.3.

[0021] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the content of the present invention.
