Description

Technical Field

[0001] This utility model relates to the field of nuclear power plant technology, specifically to a nuclear island temperature probe protection device. Background Technology

[0002] The nuclear island is the core component of a nuclear power plant, responsible for nuclear reactions and generating heat, which is then converted into electrical energy through heat exchange. During the operation of the nuclear island, ambient temperature measurements are required at various locations. Therefore, multiple temperature probes are installed at different locations for temperature monitoring. These temperature probes are critical equipment for monitoring the internal temperature of the nuclear island, and their stability and accuracy directly affect the safe operation of the nuclear power plant. However, in actual operation, the complex environment inside the island during reactor shutdown and maintenance, along with the presence of personnel crossing paths, makes the probe rods prone to bending, leading to probe failure and posing a serious threat to their normal operation. Therefore, designing a protective device that can effectively protect the temperature probes and ensure their long-term stable operation is of paramount importance. Utility Model Content

[0024] This utility model provides a protection device for a nuclear island temperature probe, such as... Figures 1-2 As shown, the device includes a sleeve 10 that matches the length of the probe rod of the temperature probe 100, and a connecting fastening assembly 20 for connecting the temperature probe 100. The diameter of the sleeve 10 is larger than the diameter of the probe rod of the temperature probe 100 to provide sufficient space for the probe rod within the sleeve 10, while preventing the probe rod from directly contacting the external environment. The outer wall of the sleeve 10 has circumferentially arranged through holes 11. These through holes 11 facilitate heat dissipation, prevent excessively high internal temperatures of the sleeve 10, improve the accuracy of temperature measurement, and also facilitate observation of the internal condition of the sleeve 10, making maintenance and repair easier.

[0025] In some preferred embodiments, the connection fastening assembly 20 includes an internal thread 21 disposed on the inner wall of the sleeve 10, the internal thread 21 matching the external thread of the probe. The threaded connection ensures a tight connection between the temperature probe 100 and the sleeve 10, preventing loosening or detachment. Furthermore, the threaded connection offers advantages such as simple structure, ease of operation, and reliable connection, making it suitable for protecting the temperature probe 100 in a nuclear island environment.

[0026] In some preferred embodiments, the fastening assembly further includes a fastener 22 disposed at one end of the sleeve 10. The fastener 22 can be in the form of a nut, bolt, etc. Tightening the fastener 22 further strengthens the connection between the temperature probe 100 and the sleeve 10, improving the stability and reliability of the connection. Simultaneously, the fastener 22 also serves as a seal, preventing moisture, dust, and other impurities from the external environment from entering the sleeve 10 and damaging the temperature probe 100. In some specific embodiments, the end of the sleeve 10 furthest from the fastening assembly 20, i.e., the measuring end of the probe, is positioned such that the end of the probe's probe does not extend beyond the end of the dustproof part 30, ensuring that the measuring end of the temperature probe 100 is within the coverage area of ​​the dustproof part 30. The dustproof part 30 effectively prevents dust, debris, etc., from entering the sleeve 10 and contaminating or damaging the measuring end of the temperature probe 100. Simultaneously, the dustproof part 30 also acts as a buffer, reducing the impact and vibration of the external environment on the temperature probe 100.

[0027] Furthermore, the dustproof part 30 is preferably funnel-shaped. The funnel-shaped dustproof part 30 not only has a larger opening area, facilitating heat exchange between the temperature probe 100 and the external environment, but also better guides airflow, reducing dust accumulation inside the dustproof part 30. In addition, the funnel-shaped dustproof part 30 is more aesthetically pleasing and meets the aesthetic requirements of industrial design.

[0028] In terms of material selection, the sleeve 10 is made of stainless steel. Stainless steel has excellent corrosion resistance and high temperature resistance, enabling it to operate stably for a long time in the nuclear island environment without corrosion or deformation. At the same time, stainless steel also has good mechanical strength and toughness, capable of withstanding certain external forces and impacts, protecting the temperature probe 100 from damage.

[0029] In a preferred embodiment, to ensure the through-hole 11 is set reasonably and effectively, the drilling position of the through-hole 11 corresponds to the position of the probe rod of the temperature probe 100. This not only ensures that the through-hole 11 can fully exert its heat dissipation function, but also avoids the through-hole 11 interfering with the measurement accuracy of the temperature probe 100. At the same time, the number and size of the through-holes 11 can also be adjusted according to actual needs to meet the requirements of heat dissipation and observation in different environments.

[0030] In some preferred embodiments, the outer side of the sleeve 10 is provided with anti-slip grooves or anti-slip protrusions. The anti-slip grooves or anti-slip protrusions facilitate installation and disassembly, while increasing the stability of the sleeve 10 and preventing it from slipping or shifting during use.

[0031] In some preferred embodiments, the inner diameter of the sleeve 10 is 15-25 mm larger than the diameter of the probe rod of the temperature probe 100. This design ensures that the probe rod can freely expand and contract within the sleeve 10, while avoiding shaking or loosening caused by excessive gaps.

[0032] In use, the probe of the temperature probe 100 is inserted into the sleeve 101 and tightly connected to the sleeve 101 using the fastening assembly 20. In this way, the sleeve 100 protects the probe of the temperature probe 100, preventing it from being directly exposed to harsh environments. At the same time, the through-hole 11 also facilitates heat dissipation and observation of the interior of the sleeve 10.

[0034] 1. Reasonable Structure: This utility model forms a complete and reliable temperature probe protection device through the combined design of a sleeve, connecting fastening components, and a dustproof part.

[0035] 2. Comprehensive Functions: The protective device of this utility model not only has basic protective functions, but also achieves heat dissipation and observation functions through the through-hole design. The through-hole helps dissipate heat inside the sleeve, preventing excessive temperature from damaging the temperature probe; at the same time, the through-hole also facilitates observation of the internal condition of the sleeve, making maintenance and repair easier.

[0036] 3. High adaptability: The protective device of this invention is made of stainless steel, which has excellent corrosion resistance and high temperature resistance, enabling it to operate stably for a long time in the nuclear island environment. Furthermore, the number and size of the through holes can be adjusted according to actual needs to meet the requirements for heat dissipation and observation in different environments.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations.
