[0023] Example: A temperature detection device for thermal cables in power plants

[0024] like Figure 1-8 As shown, a temperature detection device for thermal cables in power plants has the following specific structure:

[0025] A temperature detection device for thermal cables in power plants includes a clamping support plate 1 for supporting clamping plates for holding cables of different specifications. The clamping support plate 1 has a plurality of positioning clamping bolt holes 2 evenly spaced on its surface. Positioning clamping bolt posts 3 are provided inside the positioning clamping bolt holes 2. A positioning clamping plate 4 is fixedly attached to one end of each positioning clamping bolt post 3. A positioning clamping nut 5 is threaded onto the outer circumference of each positioning clamping bolt post 3. A spring 31 is fitted around the positioning clamping plate 4 and the clamping support plate 1, and the positioning clamping nut 5 abuts against and rotates with the clamping support plate 1. The positioning clamping plate 4 moves due to the threaded rotation of the positioning clamping nut 5 and the positioning clamping bolt post 3. The spring 31 pushes the positioning clamp 4 to position it in a certain position. Several electric push rods 6 are fixedly arranged at equal intervals on one side of the lower part of the clamp support plate 1. The telescopic end of the electric push rod 6 has a movable clamp bolt hole 7. The telescopic end of each electric push rod 6 is provided with a movable clamp 8. The movable clamp 8 is provided with a movable clamp bolt 9 on the outside of the movable clamp 8, which passes through the movable clamp 8 and is threadedly connected to the movable clamp bolt hole 7. The movable clamp 8 is fixed to the telescopic end of each electric push rod 6 through the movable clamp bolt 9 and the movable clamp bolt hole 7, so that the movable clamp 8 can move with the electric push rod 6. The positioning clamp 4 and the movable clamp 8 are fixedly provided with a temperature sensor 10 for monitoring the temperature of the cable.

[0026] The upper sides of the clamping plate support 1 are fixedly provided with pulley support plate connecting plates 11. Pulley support plates 12 are fixedly provided inside the pulley support plate connecting plates 11 on both sides. Two sets of pulley support plates 12 are arranged in a mirror image, and an adjusting bolt hole 13 is opened at the center of the side of each pulley support plate 12. Adjusting bolts 14 are inserted through the adjusting bolt holes 13 on both sides. An adjusting nut 15 is fitted onto one side of each adjusting bolt 14, threadedly engaging with it and abutting against one side of the pulley support plate 12. The distance between the two pulley support plate connecting plates 11 is adjusted by adjusting the relative position of the adjusting nut 15 and the adjusting bolt 14. Pulley column holes 16 are opened on both sides of the pulley support plate 12. A pulley column is installed inside the pulley column holes 16 on the front side of the two sets of pulley support plates 12. 17 is slidably connected to it. Limiting discs 18 are fixed on both sides of the pulley column 17 to prevent the pulley column 17 from coming out of the pulley column hole 16. A bearing sleeve 19 is sleeved in the center of the pulley column 17. A positioning pulley 20 is fixedly sleeved on the outer periphery of the bearing sleeve 19 for placement on the upper part of the cable for rotation and movement. The positioning pulley 20 is rotatably connected to the pulley column 17 through the bearing sleeve 19. Supporting springs 21 are sleeved on both sides of the pulley column 17 and are located between the pulley support plate 12 and the bearing sleeve 19 to abut against them. The supporting springs 21 on both sides ensure that the positioning pulley 20 is always in the middle position between the connecting plates 11 of the pulley support plate on both sides, so that the positioning pulley 20 is in the middle position when the device is on the upper part of the cable.

[0027] The aforementioned power plant thermal cable temperature detection device includes two sets of pulley support plates 12 with pulley column holes 16 inside which pulley columns 22 are slidably connected. A sliding limiting groove 23 is provided on one side of each pulley column 22. A rolling pulley 24 is fitted around the outer periphery of each pulley column 22. A sliding limiting strip 25 is fixedly installed inside the contact position between the rolling pulley 24 and the pulley column 22, and is fitted within the sliding limiting groove 23 for sliding connection. This allows the rolling pulley 24 to move on the pulley column 22 while being mounted via the sliding limiting strip 25. The sliding limiting groove 23 cooperates with the rolling pulley 24 to rotate synchronously with the pulley column 22. A servo motor 26 is fixedly installed on the outer side of the pulley support plate 12 on one side. The output end of the servo motor 26 is fixedly connected to the pulley column 22. The servo motor 26 drives the pulley column 22 to rotate, which in turn drives the rolling pulley 24 to rotate, thereby driving the device to move. A servo motor cover 27 is provided on the outer side of the pulley support plate 12 on one side, which is sleeved on the outside of the servo motor 26 and fixedly connected to the pulley support plate 12.

[0028] The lower part of the clamping plate support plate 1 is fixedly provided with a counterweight column connecting plate 28, and the lower part of the counterweight column connecting plate 28 is fixedly provided with a counterweight column 29 for counterweighting the bottom of the device to prevent the device from tipping over.

[0029] This solution also includes a controller, the location of which is set by the operator according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, displays, computer input devices, switches, communication devices, lights, speakers, and microphones.

[0030] Working principle:

[0031] In use, this device first adjusts the relative distance between the adjusting nut 15 and the adjusting bolt 14 to adjust the distance between the pulley support plate connecting plates 11 to adapt to the specifications of the cable to be tested. Then, the supporting spring 21 pushes the pulley support plate connecting plates 11 on both sides to fix their relative positions and position the positioning pulley 20 in the middle of the pulley support plate connecting plates 11 on both sides. Next, the positioning clamping plate 4 is moved by the threaded rotation of the positioning clamping plate nut 5 and the positioning clamping plate bolt 3. Then, the spring 31 pushes the positioning clamping plate 4 to position it in a certain position to adapt to different cable specifications. Finally, the movable clamping plate 8 is removed by unscrewing the movable clamping plate bolt 9. Then, the positioned pulley 20 is connected to the rolling... The pulley 24 is placed on the upper part of the cable to be monitored. The movable clamp 8 is then installed on the telescopic end of the electric push rod 6. Subsequently, the movable clamp 8 can be moved inward by retracting each of the electric push rods 6, so that the movable clamp 8 and the positioning clamp 4 are clamped. Then, the temperature sensor 10 provided on the surface of the movable clamp 8 and the positioning clamp 4 can monitor the cable temperature. When the device needs to be moved, the movable clamp 8 and the positioning clamp 4 are first released by extending each of the electric push rods 6. Then, the servo motor 26 is controlled to rotate, which drives the pulley column 22 and the rolling pulley 24 to rotate, so that the device can roll and move on the upper part of the cable, thereby monitoring the temperature at different positions of the cable.
