Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Example 1, reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides a real-time monitoring device for electric power engineering, including a main body 101, the main body 101 is the core part of the monitoring unit 100, the main body 101 contains a display screen 102, the display screen 102 is arranged at the front of the main body 101, and is used to display the monitoring data of the electric power engineering in real time, and is the main interface for users to obtain information, and the signal line 103 connects the display screen 102 and the signal acquisition head 103a to transmit the monitoring data. The existence of the signal line 103 is a necessary condition for realizing data transmission. The signal line 103 is arranged inside the main body 101 and is connected to the display screen 102 line, and the other end protrudes from the lower part of the main body 101.

[0031] Furthermore, five groups of wire winding grooves 201 are provided inside the main body 101, and the five groups of wire winding grooves 201 are distributed in an array. The wire winding groove 201 is used to accommodate the extension component 202 to keep the signal line 103 in order. The wire reel 202a, both ends of which are rotatably connected to the inner wall of the wire winding groove 201 through a rotating shaft, is used to wind the signal line 103 to ensure that the signal line 103 will not be messy during use. The toggle wheel 202b is set on the outside of the wire reel 202a. Rotating the toggle wheel 202b will drive the wire reel 202a to rotate, thereby achieving the effect of manually controlling the extension and contraction of the signal line 103.

[0032] Among them, the toggle groove 202e is set on the bottom surface of the main body 101 and is connected to the winding groove 201. The outer ring of the toggle wheel 202b passes through the toggle groove 202e and protrudes out of a part of the bottom of the main body 101. The toggle groove 202e is opened to rotate the toggle wheel 202b so that it can stably control the extension and contraction of the signal line 103, while allowing the toggle wheel 202b to operate outside the main body 101.

[0033] The limiting groove 202d is provided on the other side surface of the toggle wheel 202b and forms a circular ring structure around the outer ring of the toggle wheel 202b.

When the spherical end of the fixing pin 203c is movably connected in the limiting groove 202d, it can ensure that the toggle wheel 202b remains fixed when not in use. When operation is required, the toggle wheel 202b can be moved and rotated, and the spherical end of the fixing pin 203c is squeezed to one side through the curved inner wall of the limiting groove 202d, thereby forcing the fixing pin 203c to squeeze the spring 203b to move toward the bottom of the reset groove 203a, thereby achieving the effect of unlocking the toggle wheel 202b. Repeated operations can realize the control of the signal line 103.
