Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, specifically a temperature measuring device for thermal control equipment in power plants. Background Technology

[0002] Thermal control equipment in power plants is a core component ensuring the safe and stable operation of the plant. Whether its operating temperature is within a reasonable range directly affects the equipment's efficiency and service life. To monitor the temperature status of thermal control equipment in real time, the industry commonly uses temperature measuring devices for continuous monitoring. These devices need to be fixed to the surface of the thermal control equipment and maintain stable detection performance in the long-term high-temperature environment of the power plant.

[0003] In existing temperature measurement devices, the sleeves used to enclose the temperature sensing components are mostly traditional smooth tubular structures without dedicated heat dissipation components. Because power plant environments are inherently hot, and the temperature sensing components generate heat during operation, the traditional sleeves have limited heat dissipation capacity and cannot effectively dissipate the accumulated heat. This can easily lead to data drift or malfunction due to overheating, affecting the accuracy of temperature detection. Furthermore, the existing installation clamping structures are mostly of fixed specifications, lacking adjustability, and the clamping points lack buffer structures. When dealing with thermal control equipment of different sizes, either insufficient clamping force leads to loosening and inaccurate detection, or excessive clamping force directly damages the surface of the thermal control equipment, making it difficult to balance installation stability and equipment protection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temperature measuring device for power plant thermal control equipment, thereby solving the problems mentioned in the background art that affect the accuracy of temperature detection and make it difficult to balance installation stability and equipment protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature measuring device for power plant thermal control equipment, comprising:

[0006] A heat dissipation sleeve, wherein heat dissipation fins are evenly distributed on the surface of the heat dissipation sleeve, and a temperature measuring component is installed inside the heat dissipation sleeve;

[0007] An elastic clamping mechanism is provided on the surface of the heat dissipation sleeve. Both the front and rear parts of the elastic clamping mechanism are screwed with threaded rods, and the output ends of the threaded rods are all equipped with positioning clamps through a rotating shaft.

[0008] A spring is disposed on the inner wall of the positioning hoop, and a positioning cylinder is installed on the output end of each spring.

[0009] Preferably, the positioning cylinder has a semi-circular design, and the inner wall of the positioning cylinder is evenly provided with anti-slip teeth. The anti-slip teeth design can effectively increase the friction between the positioning cylinder and the part being measured when they come into contact, prevent relative sliding between the positioning cylinder and the part being measured during the temperature measurement process, and ensure the accuracy and stability of the temperature measurement.

[0010] Preferably, guide blocks are installed on both the upper and lower surfaces of the positioning hoop, and guide grooves are provided on the inner wall of the elastic clamping mechanism at positions corresponding to the guide blocks. The cooperation between the guide blocks and the guide grooves can guide the positioning hoop to move in a specific direction within the elastic clamping mechanism, preventing the positioning hoop from shifting or shaking during movement, thereby improving the installation and positioning accuracy of the entire temperature measuring device.

[0011] Preferably, a connector is installed on the surface of the heat dissipation sleeve, and a protective cap is fitted onto the protruding part of the temperature measuring component. The protective cap is screwed onto the surface of the connector. The protective cap can protect the protruding part of the temperature measuring component, preventing it from being corroded by external factors such as dust and moisture during daily use, thus extending the service life of the temperature measuring component. At the same time, the screw-on connection method also facilitates the disassembly and installation of the protective cap, making it convenient for the maintenance and repair of the temperature measuring component.

[0012] Preferably, the inner wall of the heat dissipation sleeve is uniformly provided with thermally conductive pads, and the thermally conductive pads are all connected to the surface of the temperature measuring component. The thermally conductive pads can quickly conduct the heat that the heat dissipation sleeve comes into contact with to the temperature measuring component, improve the efficiency of heat transfer, and enable the temperature measuring component to sense temperature changes more timely and accurately, thereby improving the temperature measurement response speed and accuracy of the entire temperature measuring device.

[0013] Preferably, the surface of each thermal pad is fitted with an annular retaining ring, and the temperature measuring component is installed inside the annular retaining ring. The annular retaining ring can fix and position the temperature measuring component, ensuring that the temperature measuring component is stable in the heat dissipation sleeve and will not be displaced due to external vibration or interference. This ensures that the temperature measuring component and the thermal pad always maintain good contact, thereby ensuring the reliability and stability of temperature measurement.

[0014] Compared with the prior art, this utility model provides a temperature measuring device for power plant thermal control equipment, which has the following beneficial effects:

[0015] The temperature measuring device used in the power plant's thermal control equipment features heat dissipation fins, which increase the contact area between the heat dissipation sleeve and the external environment. This effectively dissipates the heat generated by the temperature measuring components inside the heat dissipation sleeve during operation, as well as the heat transferred to the heat dissipation sleeve from the high-temperature environment of the power plant, preventing the temperature measuring components from malfunctioning due to excessive temperature. The threaded rods screwed together at the front and rear of the elastic clamping mechanism allow for adjustment of the position of the positioning clamp at its output end by rotation. The spring installed on the inner wall of the positioning clamp applies a buffering force to the positioning cylinder through its own elastic deformation when the positioning clamp clamps the thermal control equipment. This ensures the clamping stability between the positioning cylinder and the thermal control equipment and prevents excessive clamping force from damaging the surface of the thermal control equipment. As a result, the reliability and applicability of the entire temperature measuring device in the application of power plant thermal control equipment are improved, ensuring that the temperature measuring components can continuously and accurately detect the temperature of the thermal control equipment.

[0025] The temperature measurement component 3 includes a temperature sensing element, a signal transmission component, a temperature sensing element and a signal conditioning module, which can stably transmit the collected temperature signal.

[0026] The heat dissipation fins 2 evenly distributed on the surface of the heat dissipation sleeve 1 increase the contact area between the heat dissipation sleeve 1 and the external environment, thereby effectively dissipating the heat generated by the temperature measuring component 3 during operation and the heat transferred to the heat dissipation sleeve 1 by the high temperature environment of the power plant. This prevents the temperature measuring component 3 from malfunctioning due to excessive temperature and ensures the stable operation of the temperature measuring component 3. The threaded rod 5 screwed to the front and rear of the elastic clamping mechanism 4 can adjust the position of its output end positioning clamp 6 by rotation. The spring 7 set in the inner wall of the positioning clamp 6 can apply a buffering force to the positioning cylinder 8 through its own elastic deformation when the positioning clamp 6 clamps the thermal control equipment. This ensures the clamping stability between the positioning cylinder 8 and the thermal control equipment and prevents excessive clamping force from damaging the surface of the thermal control equipment. This improves the reliability and applicability of the entire temperature measuring device in the application of thermal control equipment in power plants and ensures that the temperature measuring component 3 can continuously and accurately detect the temperature of the thermal control equipment.

[0027] The positioning cylinder 8 has a semi-circular design, and the inner wall of the positioning cylinder 8 is evenly distributed with anti-slip teeth 9.

The protective cap 13 is screwed onto the surface of the connector 12. The protective cap 13 can protect the protruding part of the temperature measuring component 3, preventing it from being corroded by external factors such as dust and moisture during daily use, thus extending the service life of the temperature measuring component 3. At the same time, the screw-on connection method also makes it easy to disassemble and install the protective cap 13, facilitating the maintenance and repair of the temperature measuring component 3.

[0030] Please see Figure 2 The inner wall of the heat dissipation sleeve 1 is evenly provided with heat-conducting pads 14, which are all connected to the surface of the temperature measuring component 3. The heat-conducting pads 14 can quickly conduct the heat that the heat dissipation sleeve 1 comes into contact with to the temperature measuring component 3, improve the efficiency of heat transfer, and enable the temperature measuring component 3 to sense temperature changes more timely and accurately, thereby improving the temperature measurement response speed and accuracy of the entire temperature measuring device.

[0031] All surfaces of the thermal pads 14 are fitted with annular retaining rings 15. The temperature sensing component 3 is installed inside the annular retaining rings 15. The annular retaining rings 15 can fix and position the temperature sensing component 3, ensuring that the temperature sensing component 3 is stable in the heat dissipation sleeve 1 and will not be displaced due to external vibration or interference. This ensures that the temperature sensing component 3 and the thermal pads 14 always maintain good contact, thereby ensuring the reliability and stability of temperature measurement.

The guide blocks 10 on the upper and lower surfaces of the heat dissipation sleeve 1 cooperate with the guide grooves 11 on the inner wall of the elastic clamping mechanism 4 to guide the positioning hoop 6 to move in a specific direction, thereby improving the installation positioning accuracy. The connector 12 on the surface of the heat dissipation sleeve 1 and the screw-on protective cap 13 protect the protruding part of the temperature measuring component 3, extending its service life and facilitating maintenance and repair. The heat-conducting pad 14 on the inner wall of the heat dissipation sleeve 1 quickly conducts heat to the temperature measuring component 3, improving the temperature measurement response speed and accuracy.
