Description

Technical Field

[0001] This utility model relates to the field of substation operation and maintenance technology, and in particular to a power system operation and maintenance monitoring and display device. Background Technology

[0002] During the operation and maintenance of power substations, it is necessary to monitor all parts of the entire system. In this process, a large screen can be used to display the overall status, and multiple small screens can be set up to monitor specific parts in detail, just like a monitoring system. Because these small screens provide more detailed monitoring, the information displayed on them is more valuable during maintenance and repair, and they need to be carried around with the user.

[0003] For example, the power system operation and maintenance monitoring display device disclosed in publication number CN220191190U states that "the number of horizontal plates is three, and the number of vertical plates is six, forming two layers with four mounting holes, which can accommodate four display screens... When the display screen is placed into the mounting hole, it is initially limited by the cooperation of the shims... The screw rotates forward, and each set of screw tubes moves closer to each other with the cooperation of the threads, driving the limiting rods to move closer to each other, thus limiting the display screen." However, the size of the mounting holes in this design is fixed, which limits the selection of the size of the display screen that can be installed, thus introducing certain limitations to practical applications. Therefore, although this solution effectively realizes multi-screen installation, there is still room for improvement in adapting to the needs of display screens of different sizes.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a power system operation and maintenance monitoring display device, including a back plate 1 and a display screen 3. The top and bottom of the back plate 1 are fixedly connected to fixed limiting plates 2, and the middle of the back plate 1 is fixedly connected to a fixed plate 6. The two sides of the fixed plate 6 are slidably connected to sliders 13. The fixed plate 6 has a sliding groove 601. The slider 13 is fixedly connected to a first fixed seat 8 that slides with the sliding groove 601. The bottom of the movable limiting plate 4 is fixedly connected to a second fixed seat 11. The two ends of the connecting rod 5 are rotatably connected to the first fixed seat 8 and the second fixed seat 11 respectively through a rotating shaft. A bidirectional screw 10 is rotatably installed inside the fixed plate 6. The two sets of sliders 13 are respectively threadedly connected to the two ends of the bidirectional screw 10. A handwheel 7 is fixedly connected to one end of the bidirectional screw 10 that passes through the fixed plate 6. The display screen 3 is set between the fixed limiting plate 2 and the movable limiting plate 4. Above the fixed plate 6, the display screen 3 is placed on the movable limiting plate 4; below the fixed plate 6, the display screen 3 is placed on the fixed limiting plate 2. Rotating the handwheel 7 drives the bidirectional lead screw 10 to rotate clockwise. According to the threaded transmission principle, this drives the two sets of sliders 13 to move towards each other. Under the linkage of the connecting rod 5, the upper movable limiting plate 4 is pushed, causing the display screen 3 to abut against the fixed limiting plate 2, and the lower movable limiting plate 4 to abut against the top of the lower display screen 3. This achieves simultaneous fixing of multiple display screens 3. The structure is simple, the operation is convenient, and the size of the display screen 3 that can be installed is not limited, making it suitable for carrying and installing display screens 3 of different sizes, improving the device's versatility. When the drive handwheel 7 reverses, it drives the movable limiting plate 2 to descend, loosening the clamp on the display screen 3, facilitating the installation and removal of the display screen 3.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, a roller 12 is installed on the side of the movable limiting plate 4 near the back plate 1. A track 101 adapted to the roller 12 is provided on the back plate 1. The roller 12 cooperates with the track 101 to support the movable limiting plate 4 and facilitate its movement.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, both the fixed limiting plate 2 and the movable limiting plate 4 are provided with limiting grooves to accommodate the display screen 3, which limit the display screen 3 laterally and prevent the display screen 3 from flipping forward out of the back plate 1. A rubber layer 9 is bonded to the groove wall of the limiting groove, which protects the outer wall of the display screen 3 and prevents wear. At the same time, the rubber layer 9 has an elastic pressing effect, which can further improve the clamping stability of the display screen 3.

[0030] Working principle: In use, the display screen 3 is placed on the movable limiting plate 4 above the fixed plate 6, and on the fixed limiting plate 2 below the fixed plate 6. By rotating the handwheel 7, the double-acting screw 10 is rotated clockwise. According to the screw transmission principle, the two sets of sliders 13 are driven to move towards each other. Under the linkage of the connecting rod 5, the upper movable limiting plate 4 is pushed to make the display screen 3 abut against the fixed limiting plate 2, and the lower movable limiting plate 4 abuts against the top of the lower display screen 3. This achieves simultaneous fixation of multiple sets of display screens 3. The structure is simple and easy to operate. Moreover, the size of the display screen 3 that can be installed is not limited. It is compatible with display screens 3 of different sizes for carrying and installation, improving the versatility of the device.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
