Description

Technical Field

[0001] This utility model belongs to the field of monitoring equipment technology, and in particular relates to a DCS control video monitoring and display device for thermal power plants. Background Technology

[0002] With the increasing maturity of large-screen display technology, thermal power plants are now equipped with video surveillance devices. These devices primarily display real-time video from various monitoring points within the power plant, ensuring equipment and personnel safety. Operators can select monitoring points using the on-screen keyboard. Currently, most manufacturers integrate DCS systems with video surveillance display devices. A search reveals a patent application (application number 202320965902.3) disclosing a DCS-controlled video surveillance display device for thermal power plants. This device includes a base plate with an adjustment mechanism on its upper surface. The adjustment mechanism includes a fixed plate fixedly mounted on the upper surface of the base plate. A fixed seat is fixedly connected to the right surface of the fixed plate. An arc-shaped plate is fixedly connected to the outer periphery of the fixed seat. A limit groove is formed within the arc-shaped plate. A first threaded groove is formed within the fixed seat. A threaded rod is threadedly connected to the upper surface of the first threaded groove, and the limit plate is sleeved on the threaded rod.

[0003] However, in actual use, the applicant found that the display screen is fixed with nuts. When the angle of the display screen needs to be adjusted, the personnel need to loosen the nuts and then move the adjustment plate connected to the back of the display screen along the arc plate to adjust the angle of the display screen. After adjusting to the required angle, the nuts need to be tightened again, which makes the angle adjustment of the display screen inconvenient. In view of this, we propose a DCS control video monitoring display device for thermal power plants. Utility Model Content

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.

[0024] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0025] A DCS control video monitoring display device for a thermal power plant includes a base 1 and a display screen 5. A support base 3 is rotatably connected to the top of the base 1 via a hinge shaft 2. A connecting support 11 is symmetrically fixed to the top of the base 1, and a lower support 31 is fixedly fixed to the bottom of the support base 3. The lower support 31 and the connecting support 11 are rotatably connected via the hinge shaft 2. L-shaped fixing frames 4 are symmetrically arranged on the top of the support base 3. The display screen 5 is fixed between two L-shaped fixing frames 4. The inner sidewall of the L-shaped fixing frames 4 has openings... The limiting grooves 41 are respectively fitted into the two sides of the display screen 5. The limiting grooves 41 are used to limit the display screen 5 in the horizontal direction. The top of the L-shaped fixing frame 4 is provided with a limiting plate 42. The top of the display screen 5 is attached to the bottom of the limiting plate 42. The limiting plate 42 is used to limit the display screen 5 in the vertical direction. The rear side of the support base 3 is symmetrically and vertically fixed with columns 32. The top of the base 1 on the rear side of the support base 3 is fixedly connected to the support frame 6. An internal sliding block 8 is connected, and a guide groove is provided on the upper part of the support frame 6. The two ends of the sliding block 8 slide along the guide grooves on both sides. A lead screw 7 is rotatably connected to the top of the support frame 6 through a bearing. The lower end of the lead screw 7 is threaded into the threaded groove on the top of the sliding block 8, and an adjusting handle 71 is fixedly provided on the upper end of the lead screw 7. The two ends of the sliding block 8 are movably connected to two columns 32 through connecting rods 9. Rear axle heads 81 are symmetrically fixed on both sides of the sliding block 8. An adjustment handle 71 is fixedly provided on the outer wall of each of the two columns 32. It has a front axle head 321, the front end of the connecting rod 9 is rotatably connected to the front axle head 321, and the rear end of the connecting rod 9 is rotatably connected to the rear axle head 81. By rotating the lead screw 7, the slide 8 is driven to move vertically. Through the cooperation of the rear axle head 81, the connecting rod 9 and the front axle head 321, the column 32 and the support base 3 can be driven to rotate around the hinge axis 2. Thus, the support base 3 can drive the L-shaped fixing frame 4 and the display screen 5 to rotate around the hinge axis 2, and the angle of the display screen 5 can be quickly adjusted, making it more flexible to use.

[0026] L-shaped mounting bracket 4 is slidably mounted above support base 3. A T-shaped slider 43 is located at the bottom of the L-shaped mounting bracket 4, and slides along a T-shaped groove on the top of support base 3. A double-ended screw 10 is rotatably connected to the inside of support base 3 via bearings. The threads at both ends of the double-ended screw 10 rotate in opposite directions, and both ends of the double-ended screw 10 are threaded through the lower parts of the two L-shaped mounting brackets 4. The two ends of the double-ended screw 10 are threaded through the T-shaped slider 43 at the bottom of the two L-shaped mounting brackets 4. By rotating the double-ended screw 10, the two L-shaped mounting brackets 4 can be moved closer or further away simultaneously. One end of the double-ended screw 10 extends to the outside of support base 3 and is fixedly mounted with a handle 101. Anti-slip teeth are evenly distributed on the periphery of the handle 101 for anti-slip purposes. By rotating the double-ended screw 10 counterclockwise, the two L-shaped mounting brackets 4 can be moved further away simultaneously, allowing the display screen 5 to be quickly removed from between the two L-shaped mounting brackets 4, facilitating disassembly and maintenance of the display screen 5 and improving its usability.

[0027] Working principle: When the angle of the display screen 5 needs to be adjusted, the adjustment handle 71 can be manually turned to drive the lead screw 7 to rotate. The rotation of the lead screw 7 can drive the slide 8 to move vertically along the slide groove on the support frame 6. At this time, through the cooperation of the rear axle head 81, the connecting rod 9 and the front axle head 321, the column 32 and the support base 3 can be driven to rotate around the hinge axis 2. Thus, the support base 3 can drive the L-shaped fixing frame 4 and the display screen 5 fixed on it to rotate around the hinge axis 2, so that the angle of the display screen 5 can be quickly adjusted. When the display screen 5 needs to be disassembled and maintained, the handle 101 can be manually turned counterclockwise to drive the double-headed screw 10 to rotate. The rotation of the double-headed screw 10 can drive the two T-shaped sliders 43 to move away synchronously along the T-shaped slide groove on the top of the support base 3. Thus, the two T-shaped sliders 43 can drive the two L-shaped fixing frames 4 to move away synchronously. At this time, the display screen 5 can be quickly removed from between the two L-shaped fixing frames 4, so that the display screen 5 can be disassembled and maintained.
