[0002] The core equipment of a power station includes transformers, switchgear, and protection devices. Its design must comply with safety regulations to ensure power supply reliability. The naming of different stations is usually related to their capacity and function. For example, "station" often refers to a regional substation, while "room / room" is used for end-point power distribution. The voltage of the power distribution room in the power station needs to be monitored online to avoid voltage fluctuations affecting the safe operation of medical devices.

[0003] When existing online voltage monitoring devices for power distribution rooms are installed and used, because they are mounted on rails inside the power distribution room, the plug holes at the top and bottom of the voltage monitoring device are easily obstructed by the components on the upper and lower rails during wiring or line maintenance, making it inconvenient to disassemble and assemble the internal wiring of the plug holes, thus affecting the convenience of subsequent line maintenance.

[0004] Therefore, this utility model provides an online monitoring device for station buildings to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figure 1-6 As shown, this utility model provides an online monitoring device for a station, including a voltage monitoring device 1, a support shaft 16 fixedly connected to the rear side of the voltage monitoring device 1, a positioning plate 2, a positioning hole 22 opened on the front of the positioning plate 2 corresponding to the support shaft 16, and a storage groove 21 opened at the center of the front of the positioning plate 2; a telescopic component 3, which is distributed between the voltage monitoring device 1 and the positioning plate 2, and is used for horizontal displacement support of the voltage monitoring device 1, and is folded and stored inside the storage groove 21; and a positioning component 4, which is set on the side where the voltage monitoring device 1 and the positioning plate 2 are close to each other, and is used for self-locking control of the close contact between the voltage monitoring device 1 and the positioning plate 2. Through the folding telescopic structure of the telescopic component 3, by pulling the voltage monitoring device 1 forward, the voltage monitoring device 1 can be moved forward when the telescopic component 3 is unfolded, thereby expanding the operating space at both ends of the voltage monitoring device 1 and facilitating the maintenance operation of the line.

[0034] Furthermore, the voltage monitoring device 1 has protective covers 11 symmetrically hinged on the front. Both the upper and lower sides of the voltage monitoring device 1 have insertion holes 12. A threaded rod 15 is threadedly connected to the center of the insertion hole 12 on the front of the voltage monitoring device 1. A first copper plate 13 is fixedly connected inside the insertion hole 12, and a second copper plate 14 is slidably arranged inside the insertion hole 12. The top of the second copper plate 14 is rotatably connected to the bottom of the threaded rod 15 via a stepped shaft. The sides of the first copper plate 13 and the second copper plate 14 that are close to each other are wavy, and the wavy surface is provided with anti-slip texture. By rotating the threaded rod 15, the second copper plate 14 can be moved up and down. The close proximity of the second copper plate 14 and the first copper plate 13 can create a wavy fold on the wire inserted between them, thereby increasing the friction between the wire and the first copper plate 13 and the second copper plate 14 and preventing the wire from slipping and falling off.

[0035] Furthermore, the telescopic assembly 3 includes a first hinge seat 31, which is fixedly connected to the inner wall of the storage groove 21. A first hinge rod 32 is hinged to the other end of the first hinge seat 31, and a second hinge rod 33 is hinged to the other end of the first hinge rod 32. A second hinge seat 34 is hinged to the other end of the second hinge rod 33, and the second hinge seat 34 is fixedly connected to the rear side of the voltage monitoring device 1. Multiple sets of telescopic assemblies 3 are correspondingly distributed in the corners of the storage groove 21, and are connected by the first hinge rod 32 and the second hinge rod 33. The hinged design allows the first hinge rod 32 to unfold into a straight line when the voltage monitoring device 1 and the positioning plate 2 are far apart. Conversely, when they are close together, the first hinge rod 32 and the second hinge rod 33 are folded and staggered and stored inside the storage slot 21. This allows the voltage monitoring device 1 and the positioning plate 2 to contact each other. Furthermore, the insertion and positioning of the support shaft 16 and the positioning hole 22 provides good support for the close contact between the voltage monitoring device 1 and the positioning plate 2, reducing the downward load on the telescopic component 3.

[0036] Furthermore, the positioning component 4 includes a first ratchet plate 43 and a second ratchet plate 46. A insertion slot 17 adapted to the horizontal sliding displacement of the first ratchet plate 43 is provided on the rear side of the voltage monitoring device 1. The second ratchet plate 46 is fixedly connected to the side of the positioning plate 2 near the voltage monitoring device 1. A pull rod 42 is fixedly connected to the side of the first ratchet plate 43 away from the second ratchet plate 46. One end of the pull rod 42 passes through the center of the insertion slot 17, and the other end extends to the outside of the voltage monitoring device 1. A pull ring 41 is fixedly connected to the other end of the pull rod 42. A telescopic shaft 44 is fixedly connected to the side of the first ratchet plate 43 away from the second ratchet plate 46. The other end of the telescopic shaft 44 is fixedly connected to the inner wall of the insertion slot 17. A spring 45 is sleeved on the outside of the telescopic shaft 44, and both ends of the spring 45 abut against the first ratchet plate 43 and the insertion slot 17, respectively. The positioning component 4 is provided with two... The voltage monitoring device 1 is equipped with two sets of positioning components 4 symmetrically distributed on both sides. The teeth of the first ratchet plate 43 and the second ratchet plate 46 are close to each other. With this structure, when the voltage monitoring device 1 and the positioning plate 2 are close to each other, the second ratchet plate 46 is inserted into the insertion groove 17. At the same time, under the elastic support of the first ratchet plate 43, the second ratchet plate 46 can be inserted into the insertion groove 17 in one direction. In the opposite direction, it is locked by the first ratchet plate 43 and the second ratchet plate 46, which prevents the voltage monitoring device 1 and the positioning plate 2 from sliding away and ensures the stability and tightness of the contact between the voltage monitoring device 1 and the positioning plate 2. When the pull ring 41 is pulled externally, the first ratchet plate 43 is displaced by the pull rod 42, which can release the locking of the second ratchet plate 46. At this time, the voltage monitoring device 1 and the positioning plate 2 can be moved away.

[0037] Working principle: First, the positioning plate 2 is engaged with the guide rail to complete the installation and positioning of the device. Then, the telescopic component 3 is unfolded by pulling the voltage monitoring device 1. At this time, the forward movement of the voltage monitoring device 1 facilitates the maintenance of the wiring holes 12 on the upper and lower sides of the voltage monitoring device 1. After the wiring is installed, the voltage monitoring device 1 is pushed backward to make the voltage monitoring device 1 and the positioning plate 2 come into contact with each other. At this time, the second ratchet plate 46 is inserted into the insertion slot 17. Under the elastic abutment of the first ratchet plate 43, the second ratchet plate 46 is self-locked, which prevents the voltage monitoring device 1 and the positioning plate 2 from separating and improves the tightness and firmness of the connection between the voltage monitoring device 1 and the positioning plate 2.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
