Technical Field

[0001] This utility model relates to the field of instrument installation technology, specifically to an installation device for thermal control instruments used in power plant thermal control. Background Technology

[0002] Thermal control instruments used in power plants are the core of ensuring the safe, stable, and economical operation of thermal systems in thermal power plants and new energy power plants. They are mainly used to collect, monitor, and provide feedback on various key thermal parameters during unit operation in real time, providing accurate data support for operation control, fault early warning, and safety protection. Among the thermal control instruments used in power plants, thermocouples are the core equipment for measuring the temperature in the high-temperature critical areas of the unit.

[0003] Because the measurement of thermal parameters of machines in power plants requires high precision, multiple thermocouples with different measuring depths need to be installed on the machines. Although the installation depth of thermocouples in the existing technology can be adjusted, the insertion depth of the thermocouple cannot be accurately determined during installation. Therefore, it is impossible to determine the location and depth of the heat point measured by the current thermocouple in the machine. Therefore, in order to solve the above problems, a thermal control instrument installation device for power plant thermal control is proposed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thermal control instrument installation device for power plant thermal control includes a base, with a height adjustment component installed at the top of the base. The height adjustment component includes a connecting rod vertically arranged and fixedly connected to the top of the base. A nut frame is slidably connected to the outside of the connecting rod. A height measuring frame is slidably connected to the outside of the connecting rod above the nut frame.

[0014] 1. In this utility model, by setting a height adjustment component, when using the device, the nut clip frame is placed on the large screw, and the height measuring frame is placed on the bottom of the thermocouple instrument.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A thermal control instrument installation device for power plant thermal control includes a base 1, with a height adjustment component 2 installed at the top of the base 1. The height adjustment component 2 includes a connecting rod 21 vertically arranged and fixedly connected to the top of the base 1. A nut frame 22 is slidably connected to the outside of the connecting rod 21. A height measuring frame 23 is slidably connected to the outside of the connecting rod 21 above the nut frame 22. A measuring component 24 is installed on the front of the nut frame 22 and the height measuring frame 23. A positioning component 25 for fixing the nut frame 22 and the height measuring frame 23 is installed on the nut frame 22 and the height measuring frame 23. The height adjustment component 2, when using the device, involves placing the nut clip 22 on the large screw and the height measuring frame 23 on the bottom of the thermocouple instrument. Once the thermocouple measuring point is determined, the small screw on the upper part of the thermocouple is screwed into the large screw on the lower part to complete the installation of the thermocouple. At this time, the reading of the measuring scale 242 is read, and the length of the thermocouple root is subtracted from the reading to obtain the length of the thermocouple inserted into the machine. This makes the determination and measurement of the thermocouple installation depth more accurate, reduces installation errors, and enables the operator to accurately measure the heat at different depths in the machine.

[0028] A limiting rod 211 is fixedly connected to the outside of the connecting rod 21 to limit the rotation of the nut holder 22 and the height measuring frame 23. The design of the limiting rod 211 can limit the running trajectory of the nut holder 22 and the height measuring frame 23 and prevent them from rotating.

[0029] The measuring component 24 includes a limiting frame 241 fixedly connected to the front side of the height measuring frame 23. A vertically set measuring ruler 242 is slidably connected to the inner side of the limiting frame 241. The bottom of the measuring ruler 242 is fixedly connected to the outer side of the nut frame 22. The design of the measuring component 24 allows the operator to clearly observe the current depth of the thermocouple.

[0030] The positioning component 25 includes a connecting plate 251, and a threaded cylinder 252 that passes through the connecting plate 251 is fixedly connected inside the connecting plate 251. A bolt 253 is threadedly connected to the inner side of the threaded cylinder 252. The end of the bolt 253 near the connecting rod 21 is tightly fitted to the connecting rod 21. The positioning component 25 is designed to lock the nut frame 22 and the height measuring frame 23 respectively, preventing them from moving.

[0031] The top of the connecting rod 21 is equipped with a top plate 212 for sealing the height measuring frame 23. The top plate 212 is detachable, and the design of the detachable top plate 212 can prevent the height measuring frame 23 and its connecting components from detaching from the connecting rod 21.

[0032] A spring assembly 26 is provided between the nut holder 22 and the height measuring frame 23. The spring assembly 26 includes a support spring 261. The design of the spring assembly 26 can provide support for the height measuring frame 23. When the operator adjusts the height measuring frame 23, he / she only needs to press down slowly, which makes the adjustment of the height measuring frame 23 more convenient.

[0033] The upper and lower ends of the support spring 261 are fixedly connected to the fixing plates 262. The fixing plates 262 are slidably connected to the connecting rod 21. The two fixing plates 262 are provided with slots 263 on the side away from each other. The slots 263 are engaged with the locking blocks 264. The locking blocks 264 are fixedly connected to one side of the nut frame 22 and the height measuring frame 23 respectively. This design allows the staff to install and remove the spring assembly 26 as needed.

[0034] Workflow: In existing technologies, when installing thermocouples, the thermocouple is typically inserted into the internal thread of the machine, and the lower screw of the thermocouple is screwed into the machine. The thermocouple can then be lifted up and down to change its measuring point. Once the measuring point is determined, the upper small screw of the thermocouple is screwed into the lower large screw, completing the thermocouple installation. When using this device, the installation steps are the same as the traditional method. However, after screwing the lower screw into the machine, the base 1 must be placed on the machine, and the nut holder 22 must be fitted onto the large screw. The height measuring frame 23 must be fitted onto the bottom of the thermocouple gauge, ensuring that the nut holder 22 is flush with the top of the machine. Next, rotate the bolt 253 on the nut holder 22 to make it rotate inside the threaded cylinder 252 on the connecting plate 251 until the bolt 253 is tightly engaged with the connecting rod 21, thus completing the installation of the device. Afterwards, the height of the thermocouple can be adjusted up and down, causing the support spring 261 to compress and the height measuring frame 23 to slide outside the connecting rod 21. The measuring scale 242 slides relative to the limiting frame 241. Once the thermocouple measurement point is determined, use the positioning component 25 to position the height measuring frame 23. Screw the small screw on the upper part of the thermocouple into the large screw on the lower part to complete the installation of the thermocouple. After installation, the current measuring scale 242 can be read. The reading is calculated by subtracting the length of the thermocouple root from the reading to determine the insertion length of the thermocouple into the machine. After installing multiple thermocouples at different heights using this method, the device can be used normally. The design of the height adjustment component 2 makes the determination and measurement of the thermocouple installation depth more accurate, reducing installation errors and enabling operators to accurately measure the heat at different depths in the machine. The design of the limiting rod 211 restricts the running trajectory of the nut holder 22 and the height measuring frame 23, preventing them from rotating. The design of the detachable top plate 212 prevents the height measuring frame 23 and its connecting components from detaching from the connecting rod 21. The design of the measuring component 24 allows operators to... The depth of the thermocouple can be clearly observed. The positioning component 25 is designed to lock the nut frame 22 and the height measuring frame 23 respectively to prevent them from moving. The spring component 26 is designed to provide support for the height measuring frame 23. The operator only needs to press down slowly to adjust the height measuring frame 23, making the adjustment of the height measuring frame 23 more convenient. If the spring component 26 is not needed, the top plate 212 can be removed and the fixing plate 262 can be pulled to disengage the locking block 264 from the locking slot 263, thus completing the disassembly of the spring component 26. This design allows the operator to install and remove the spring component 26 as needed.
