Description

Technical Field

[0001] This utility model belongs to the technical field of steam turbine monitoring and protection devices, and specifically relates to a steam turbine monitoring and protection device. Background Technology

[0002] The HY-3500CRC intelligent remote turbine monitoring and protection device is a highly reliable, fully digital, modular, multi-functional instrument. It consists of monitoring modules for vibration, speed, axial displacement, eccentricity, thermal expansion, differential expansion, key phase, hydraulic actuator, valve position, oil tank level, and two-out-of-three overspeed protection. This device is suitable for TSI (Transient Induction System) turbine design and can be widely used in power, metallurgy, and chemical industries. The device is equipped with a remote monitoring system using a B / S (Browser / Server) architecture, allowing operation via internet access through a web browser. The system integrates sensor technology, internet technology, wireless communication technology, cloud computing technology, and other cutting-edge technologies, enabling online status monitoring and remote data acquisition of all vibration equipment in various locations on a single platform. It provides real-time monitoring of equipment operation status and features real-time alarms and push notifications of hazardous measurement data to mobile phones. Internally, the device uses various sensors and monitoring modules to collect turbine operating data in real time, providing a basis for equipment operation status assessment and control. It provides multiple parameter measurements and early fault warnings for safe turbine operation, and features convenient installation and maintenance, simple operation, high reliability, and effective equipment protection.

[0003] Turbine monitoring and protection devices are generally installed on the turbine equipment control panel using a perforated plate method. This involves creating a hole in the control panel, embedding the device, and securing it with screws. While the installation method is simple, regular maintenance is necessary to ensure proper functioning and prevent signal abnormalities caused by electromagnetic interference, blocked cooling vents, or loose terminals. This often requires disassembly, which involves frequently removing and reassembling multiple screws to remove the device from the control panel. After maintenance, reinstallation is required, making the disassembly process cumbersome. The design of not repositioning the turbine monitoring and protection device for ease of disassembly and reassembly is therefore a drawback.

[0004] The existing turbine monitoring and protection devices installed on the control panel have the problem that the installation design does not change the position of the turbine monitoring and protection devices during maintenance. Therefore, this application proposes a turbine monitoring and protection device. Utility Model Content

[0025] 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.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a steam turbine monitoring and protection device, including a steam turbine monitoring and protection device body 1 installed on the steam turbine equipment control panel. A liquid crystal display panel 11 is provided on the surface of the steam turbine monitoring and protection device body 1, and limiting plates 111 are provided on the bottom surfaces of both sides of the liquid crystal display panel 11. Figure 1In the diagram, A represents the turbine equipment control panel. The limit plate 111 is plugged into and connected to the lifting block 4. The turbine monitoring and protection device body 1 and the lifting block 4 are separate structures, facilitating disassembly of the turbine monitoring and protection device body 1 and its maintenance. The support frame includes a mutually perpendicular base plate 21 and a support plate 22, and a mounting block 221 at the corner of the top of the support plate 22. The base plate 21 and support plate 22 are fixed with screws, and the mounting block 221 is glued to the support plate 22. The support frame is installed on the control panel A. The base plate 21, support plate 22, and wire baffle 23 are embedded inside the control panel A. The mounting block 221 is fixed to the control panel A with screws. The surface of the base plate 21 has a vertical wire baffle 23, which is glued to the base plate 21. The wire baffle 23 serves to block the wire. A winding rod 5 is vertically mounted on the bottom surface of the base plate 21. A guide is connected to the bottom of the turbine monitoring and protection device body 1. When the conductor is too long and needs to be wound up, part of the conductor is wound on the outside of the winding rod 5, and part of the conductor is stored in the space between the base plate 21 and the turbine monitoring and protection device body 1, which has the function of winding the conductor. The base plate 21 is rotatably connected to both sides with a clamping spring plate 6, which is made of spring steel and serves to clamp the conductor that passes around the winding rod 5. The lifting assembly includes an electric push rod 3 whose bottom end is fixed to the base plate 21 by screws, and a lifting block 4 fixed to the top end of the electric push rod 3 by screws. The electric push rod 3 is electrically connected to an external power supply. When the electric push rod 3 is opened, the electric push rod 3 changes from a shortened state to an extended state. The electric push rod 3 drives the lifting block 4 and the turbine monitoring and protection device body 1 to move. The turbine monitoring and protection device body 1, which is inserted into the operating platform A, moves to the outside of the operating platform A, which facilitates the disassembly of the turbine monitoring and protection device body 1, which is separately combined with the lifting block 4, for maintenance.

[0027] In this embodiment, the limiting insert plate 111 has an "L" shaped structure, and the surface of the lifting block 4 is provided with an installation groove for the limiting insert plate 111 to be inserted. The limiting insert plate 111 is inserted into the interior of the lifting block 4. The turbine monitoring and protection device body 1 and the lifting block 4 are separate structures, which facilitates the disassembly of the turbine monitoring and protection device body 1.

[0028] In this embodiment, the lifting block 4 and the mounting block 221 have the same thickness and width, the top surfaces of the lifting block 4 and the mounting block 221 on the same side are flush, and the opposite surface of the lifting block 4 is in contact with the surface of the opposite mounting block 221.

[0029] In this embodiment, the wire baffle 23 is perpendicular to the support plate 22. The wire baffle 23 is mesh-like and blocks part of the wires stored between the base plate 21 and the turbine monitoring and protection device body 1. A wire-passing groove 211 is provided at the center of the surface of the base plate 21 facing the turbine monitoring and protection device body 1. The wires can pass through the wire-passing groove 211. The distance between the base plate 21 and the turbine monitoring and protection device body 1 is the spacing H. The distance between the turbine monitoring and protection device body 1 and the wire baffle 23 is 5 mm. The bottom of the turbine monitoring and protection device body 1 is connected to a wire. When the wire is too long and needs to be wound up, part of the wire is wound on the outside of the winding rod 5, and part of the wire is stored in the space between the base plate 21 and the turbine monitoring and protection device body 1, which has the function of winding the wire.

[0030] In this embodiment, the clamping spring plate 6 includes a fixed end and a movable end, which are curved arc-shaped. The fixed end of the clamping spring plate 6 has a fixed post 61 passing through it. The movable end of the clamping spring plate 6 has a vertical protrusion 62 at its end. One end of the protrusion 62 is spherical. Pulling the protrusion 62 causes the clamping spring plate 6 to tilt up. Then, the clamping spring plate 6 is rotated around the fixed post 61 as an axis, which can change the position of the clamping spring plate 6 without affecting the wire being wrapped around the outside of the winding rod 5. Then, the clamping spring plate 6 is rotated in the opposite direction and the protrusion 62 is released, and the clamping spring plate 6 presses the wire wrapped around the outside of the winding rod 5.

[0031] Working principle and usage process of this utility model:

[0032] When installing the turbine monitoring and protection device body 1 on the control panel A, the support frame and the lifting assembly are combined as an adjustment seat for installing the turbine monitoring and protection device body 1, that is, the electric push rod 3 is fixed to the base plate 21 by screws.

[0033] Pull the protruding post 62 to make the clamping spring plate 6 tilt up. Then rotate the clamping spring plate 6 around the fixed post 61 as the axis to change the position of the clamping spring plate 6. Wrap part of the wire around the outside of the winding rod 5. Then rotate the clamping spring plate 6 in the opposite direction and release the protruding post 62. The clamping spring plate 6 will then press the wire wrapped around the outside of the winding rod 5.

[0034] Insert the aforementioned adjustment seat into the mounting hole provided on the operating table A, and insert the base plate 21 and the support plate 22 into the interior of the operating table A;

[0035] Mounting block 221 is securely fastened to operating panel A with screws. The adjusting seat, which is formed by the combination of support frame and lifting assembly, is in a secure state. Subsequently, during the disassembly and assembly of turbine monitoring and protection device body 1, the adjusting seat is in a fixed state.

[0036] At this time, the electric actuator 3 is in the extended state of being opened. One end of the wire is passed through the wire groove 211 and connected to the turbine monitoring and protection device body 1. The turbine monitoring and protection device body 1 is combined with the lifting block 4, so that the limit plate 111 is inserted into the interior of the lifting block 4.

[0037] When the electric actuator 3 is in the shortened state, the turbine monitoring and protection device body 1 and the lifting block 4 move simultaneously, the turbine monitoring and protection device body 1 is inserted into the operating table A, and the turbine monitoring and protection device body 1 is located between the opposing support plates 22.

[0038] When the turbine monitoring and protection device body 1 is disassembled for maintenance, the electric push rod 3 changes from a shortened state to an extended state. The electric push rod 3 drives the lifting block 4 and the turbine monitoring and protection device body 1 to move. The turbine monitoring and protection device body 1 inserted into the operating platform A moves to the outside of the operating platform A, which makes it easier to disassemble the turbine monitoring and protection device body 1, which is separately combined with the lifting block 4, for maintenance.

[0039] In summary: The turbine monitoring and protection device of this application has an installation design that allows it to change its position. Driven by the electric push rod 3, the lifting block 4 and the turbine monitoring and protection device body 1 are moved to the outside of the operating platform, which facilitates the disassembly and maintenance of the turbine monitoring and protection device body 1, which is separately combined with the lifting block 4.

[0040] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
