Description

Technical Field

[0001] This application relates to the field of power cabinet technology, and in particular to an integrated instrument panel for a power cabinet with multi-functional monitoring capabilities. Background Technology

[0002] Power supply cabinets are key equipment in power systems used for distributing, controlling, and monitoring power transmission. They integrate core components such as circuit breakers, relays, and measurement modules, and must maintain stable operation under complex conditions. The instrument panel serves as a "visual window" for the power supply cabinet, displaying voltage and current information within the cabinet.

[0003] The prior art CN201610491152.5 discloses an adjustable instrument panel electrical cabinet, including an instrument panel assembly mounted on a fixed shaft. The instrument panel assembly includes: two fixed plates fixedly connected to the bottom of the instrument panel and slidably engaged in a separately mounted fixed base; and two rotation locking sliders slidably mounted on the fixed shaft and symmetrically arranged on the upper and lower sides of the two fixed plates. Each rotation locking slider includes a sleeve portion sleeved on the fixed shaft and two inclined plates separately arranged and fixed to the front and rear sides of the sleeve portion.

[0004] The aforementioned existing instrument panels are traditional pointer-type instrument panels, which can only monitor single data items within the power cabinet, resulting in limited functionality. When multiple information needs to be displayed, multiple instrument panels are required, making the device wiring more complex. Operators need to check and read the data from each panel to obtain the corresponding information, which is inconvenient. In addition, some existing integrated instrument panels are installed in the cabinet door using embedded or bolt-fixed methods. Although they can meet basic display requirements, they are prone to loosening and display misalignment under vibration. This can cause the integrated instrument panel to become loose, and its internal wiring interfaces are prone to poor contact due to vibration and friction. This can lead to interruption or delay in the acquisition of key parameters such as voltage and current, and the display screen may show data jumps, garbled characters, or even a black screen. Operators cannot accurately judge the actual operating status of the power cabinet, increasing the risk of misjudgment.

[0005] Therefore, this application proposes an integrated instrument panel for a multi-functional monitoring power cabinet. Utility Model Content

[0006] To address the problems mentioned in the background section, this application provides an integrated instrument panel for a multifunctional monitoring power cabinet.

[0007] This application provides an integrated instrument panel for a multi-functional monitoring power cabinet, which adopts the following technical solution: it includes a display screen, which is embedded in the side door. The side door is hinged to the front end of the cabinet. The cabinet cavity is also provided with a measurement module and a secondary wiring harness for monitoring. The measurement module and the display screen are connected by a communication serial cable. An installation component is provided between the display screen and the inner wall of the side door. The installation assembly includes a threaded post fixedly installed at the rear of the display screen, a limiting tube, and an external threaded tube threadedly connected to the threaded post. Both the threaded post and the limiting tube movably pass through the side door. A limiting unit is provided between the limiting tube and the external threaded tube. The limiting unit includes a ring, a fixing post, and a cylindrical rod. The cylindrical rod can be movably engaged with the limiting tube.

[0008] Optionally, the measurement module is electrically connected to the secondary wiring harness, and the measurement module is connected to a relay.

[0009] Optionally, the inner diameter of the externally threaded tube is larger than that of the threaded post, and a rubber gasket is provided between the externally threaded tube and the side door.

[0010] Optionally, the outer wall of the externally threaded pipe is provided with an annular groove, the ring is movably engaged in the annular groove, and the fixing pile is fixedly installed on the outer wall surface of the ring.

[0011] Optionally, a cylindrical movable cavity is provided on the side of the fixed pile near the side door, and a through hole is provided between the cylindrical movable cavity and the outer wall of the fixed pile.

[0012] Optionally, one end of the cylindrical rod can be movably inserted through the hole and engaged with the limiting tube, and the end of the cylindrical rod away from the limiting tube is fixedly connected to a pull plate.

[0013] Optionally, a retaining ring is fixedly installed on the outer wall of the cylindrical rod, and the retaining ring is movably engaged in the cylindrical movable cavity of the fixed pile. A compression spring is also sleeved on the outer wall of the cylindrical rod, and the compression spring is located between the retaining ring and the through hole.

[0014] In summary, this application includes the following beneficial technical effects: This utility model, by setting up components such as a display screen, cabinet, side door, measurement module, secondary wiring harness, and communication serial port, allows the measurement module to collect key parameters such as voltage, current, and temperature of the power cabinet in real time. The data is then transmitted to the display screen for visualization using the secondary wiring harness and communication serial port. By setting up installation components and limiting units, the threaded connection between the threaded post and the external threaded tube, combined with rubber gaskets, ensures a stable installation of the display screen. The limiting unit further restricts the reverse rotation of the external threaded tube after it is tightened with the threaded post, preventing loosening due to vibration or other factors. This ensures the long-term stability of the installation structure and facilitates flexible adjustment of the display screen's installation height and angle, adapting to different scenario requirements and improving the versatility and maintenance convenience of the integrated instrument panel.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0018] This application discloses an integrated instrument panel for a multi-functional monitoring power cabinet. For example... Figure 1 and Figure 2As shown, the cabinet includes a cabinet 10, which provides a closed and stable installation space for all internal components. It also provides physical protection for the internal components, isolating them from external dust, moisture, and other interference. A side door 11 is hinged to the front of the cabinet 10, allowing for flexible opening and closing. This facilitates maintenance and repair of the internal components by operators and also allows the cabinet to close smoothly when shut. A closed structure is formed to protect the safety of internal components. A display screen 12 is embedded in the outer wall of the side door 11 to present the monitoring data in a visual form. The cabinet 10 cavity is also equipped with a measurement module 13 and a secondary wiring harness 14 for monitoring. It can collect key parameters such as voltage, current and temperature in real time. The measurement module 13 and the secondary wiring harness 14 are connected by electrical signals. The measurement module 13 is connected to a relay. When the parameters are abnormal, the relay is triggered to realize power protection. The measurement module 13 and the display screen 12 are connected by a communication serial port 15 to ensure that the parameters collected by the measurement module 13 can be accurately and in real time transmitted to the display screen 12 for display. The whole system realizes multi-functional and high-precision monitoring of the power cabinet, improving the safety and controllability of the power cabinet operation.

[0019] It should be noted that the display screen 12, the measurement module 13 and the secondary wiring harness 14 are all existing technologies known to those skilled in the art, and will not be described in detail here.

[0020] Please see Figure 3 and Figure 4 The mounting assembly 16 includes a threaded post 17, a limiting tube 18, and an external threaded tube 19 that is threadedly connected to the threaded post 17, which are fixedly installed at the rear end of the display screen 12. This provides a mounting base for the display screen 12. Both the threaded post 17 and the limiting tube 18 can move through the side door 11. The limiting tube 18 is set parallel to the threaded post 17 and plays an auxiliary limiting role in the installation of the display screen 12, preventing the display screen 12 from swaying left and right or shifting at an angle due to uneven force after installation. The inner diameter of the external threaded tube 19 is larger than that of the threaded post 17. When the external threaded tube 19 is threadedly connected to the threaded post 17, its inner wall can completely cover the part of the threaded post 17 that passes through the side door 11. By tightening the external threaded tube 19, a rubber gasket is provided between the external threaded tube 19 and the side door 11. With the help of the rubber gasket, the display screen 12 can be firmly fixed to the side door 11. The rubber gasket can also buffer the pressure during installation. The threaded connection design allows the installation height and angle of the display screen 12 to be flexibly adjusted to adapt to different installation scenarios and operating requirements, thereby improving the versatility of the integrated instrument panel.

[0021] Please see Figure 5A limiting unit is provided between the limiting tube 18 and the external threaded tube 19. The limiting unit includes a ring 20, a fixing post 23, and a cylindrical rod 25. The limiting unit is used to further restrict the reverse rotation of the external threaded tube 19 after it is tightened with the threaded post 17, to prevent it from loosening due to vibration and other factors, and to ensure the long-term stability of the installation structure. The cylindrical rod 25 can be movably engaged with the limiting tube 18. An annular groove 22 is opened on the outer wall of the external threaded tube 19, and the ring 20 is movably engaged in the annular groove 22. The fixing post 23 is fixedly installed on the outer wall of the ring 20. A cylindrical movable cavity is opened on the side of the fixing post 23 near the side door 11, and a through hole 24 is opened between the cylindrical movable cavity and the outer wall of the fixing post 23 for the cylindrical rod 25 to pass through, so that the cylindrical rod 25 can move flexibly along the axial direction. One end of the cylindrical rod 25 can movably pass through the through hole 24 and engage with the limiting tube 18. The end of the cylindrical rod 25 away from the limiting tube 18 is fixedly connected to a pull plate 28 for operator control. A retaining ring 26 is fixedly installed on the outer wall of the cylindrical rod 25. The retaining ring 26 is movably engaged in the cylindrical movable cavity of the fixed pile 23. A compression spring 27 is also sleeved on the outer wall of the cylindrical rod 25. The compression spring 27 is located between the retaining ring 26 and the through hole 24. The movable engagement design of the ring 20 in the annular groove 22 allows the fixed pile 23 to rotate synchronously with the external threaded tube 19, ensuring that the cylindrical rod 25 can always be accurately aligned with the limiting tube 18, avoiding limit failure due to rotational misalignment, and improving the reliability of the limit structure. The cooperation between the retaining ring 26 and the compression spring 27 ensures that the cylindrical rod 25 always remains engaged when there is no external force intervention, achieving continuous limit without additional operation. The ingenious structural design and convenient operation further enhance the practicality of the installation component 16.

[0022] The implementation principle of the integrated instrument panel for a multi-functional monitoring power cabinet in this application embodiment is as follows: In use, firstly, a mounting hole is opened on the side door 11. The operator aligns the threaded post 17 and the limiting tube 18 at the rear end of the display screen 12 with the corresponding mounting hole on the side door 11, and then threads the external threaded tube 19 to the threaded post 17. Since the outer diameter of the external threaded tube 19 is larger than that of the threaded post 17, its inner wall can completely cover the part of the threaded post 17 that passes through the side door 11. During the tightening of the external threaded tube 19, the rubber gasket between the external threaded tube 19 and the side door 11 is squeezed, which can play a buffering role and prevent damage to the surface of the side door 11. At the same time, the limiting tube 18, which is set parallel to the threaded post 17, can effectively prevent the display screen 12 from swaying left and right or shifting at an angle due to uneven force, ensuring the stability in the initial stage of installation.

[0023] Then, after tightening the external threaded tube 19, rotate the ring 20. The operator pulls the pull plate 28 by hand, and the pull plate 28 drives the cylindrical rod 25 to move. Then, the cylindrical rod 25 is moved into the cavity of the corresponding limiting tube 18, so that the cylindrical rod 25 and the limiting tube 18 are engaged to prevent it from loosening due to vibration and other factors during subsequent use, and further ensure the long-term stability of the installation structure.

[0024] Finally, during the operation of the power cabinet, the measurement module 13 inside the cabinet 10 collects key parameters such as voltage, current, and temperature in real time, transmits electrical signals to relevant components through the secondary wiring harness 14, and triggers the relay to protect the power supply when the parameters are abnormal. The parameters collected by the measurement module 13 are accurately and in real time transmitted to the display screen 12 through the communication serial cable 15 and presented in a visual form, so that the operator can intuitively grasp the operating status of the power cabinet.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
