Description

Technical Field

[0001] This utility model relates to the field of temperature clustering technology, and in particular to an easily replaceable temperature clustering structure. Background Technology

[0002] In industrial production, large fans are key pieces of equipment, and the stable monitoring of their bearing operating temperatures is crucial for equipment safety and continuous production. Traditional large fan bearing housings are typically equipped with multi-point temperature detection devices, which employ a single-point, clustered integrated design.

[0003] However, this design has obvious flaws: Firstly, when abnormal fluctuations or bad values ​​occur at a certain temperature point, it is impossible to quickly determine the authenticity of the abnormality. In order to avoid damage to the fan, it is often necessary to take the method of interlocking shutdown and disassembling the machine for inspection, which leads to production interruption. Secondly, the temperature point is installed on the bearing bush that slides in contact with the bearing. The internal structure of the equipment is complex. Each replacement and maintenance requires the machine to be shut down and a large number of professional maintenance personnel to disassemble the relevant structure to expose the temperature installation position. This not only makes the maintenance time long, but also increases labor costs and production time costs. Third, if a single temperature detection component fails, the entire temperature cluster usually needs to be replaced, which significantly increases the cost of spare parts.

[0004] For industrial production scenarios that require high continuous operation rates, frequent downtime for maintenance, long maintenance time, and high spare parts costs seriously affect the stability of enterprise production and increase operating costs. Therefore, there is an urgent need for a temperature clustering structure that can solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an easily replaceable temperature clustering structure, which solves the technical problems of unreliable single-point temperature detection in traditional fan bearing and similar large motor temperature clustering devices, easy interference leading to equipment shutdown, and the need for complete replacement after damage, which are difficult to disassemble and repair, have long maintenance time, and high spare parts costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An easily replaceable temperature cluster structure includes a thermometer section and a mounting flange section; The thermometer includes a redundant temperature measurement probe, a metal-sealed package, a signal line armor, a protective heat shrink tubing, and a pin-shaped wire nose. The metal-sealed package is fitted over the signal output end of the redundant temperature measurement probe. One end of the signal line armor is connected to the end of the metal-sealed package away from the redundant temperature measurement probe. The protective heat shrink tubing is fitted over the end of the signal line armor away from the metal-sealed package. The pin-shaped wire nose is connected to the end of the temperature signal line inside the signal line armor. The mounting flange includes a flange of the same specifications as the mounting position and a terminal sealing joint. The flange has a mounting hole for the terminal sealing joint. The mounting hole of the terminal sealing joint has an internal thread that is compatible with the external thread of the terminal sealing joint. The terminal sealing joint is threaded into the mounting hole of the terminal sealing joint. The metal sealing package passes through the central hole of the terminal sealing joint and is fixed and sealed by the terminal sealing joint.

[0007] Preferably, the flange is further provided with flange fixing screw holes, which are used to fix the flange to the temperature detection installation preset position of the fan bearing.

[0008] Preferably, the number of mounting holes of the terminal sealing joint can be increased or decreased according to the user's actual needs.

[0009] Preferably, the redundant temperature measurement probe is installed in the temperature detection mounting position on the fan itself to detect the temperature of the fan bearing.

[0010] Preferably, the needle-shaped pressure lug is used to connect to the user's field signal collection box, which is used to transmit the temperature signal to the DCS or PLC control system. The dimensions of the flange are consistent with the dimensions of the preset temperature detection mounting position of the fan bearing, without changing the original structure of the fan.

[0011] Preferably, the metal sealing package and the center hole of the terminal sealing connector are sealed together to prevent external impurities from entering the structure. There are multiple redundant temperature measurement probes. When one of the redundant temperature measurement probes is damaged, it can be replaced by the other redundant temperature measurement probes without stopping the machine for maintenance.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention replaces the original single-point temperature design with a redundant temperature design, allowing for dual-point interlocking or use as a reference point according to user needs. When one temperature point fails, other redundant temperature points can be used directly as replacements, eliminating the need for downtime maintenance and significantly reducing the frequency of fan shutdowns, thus ensuring continuous production.

[0013] It features easy replacement; when a single temperature sensing component is damaged, only the corresponding thermometer needs to be replaced, without disassembling or replacing other normal temperature sensing components and mounting flanges. This significantly shortens the fan downtime for maintenance and reduces the cost of spare parts procurement and replacement.

[0014] The flange size and specifications of the mounting flange are consistent with the original preset temperature mounting position of the fan bearing, and it can be directly installed in the original preset position without changing the original structure of the fan; the thermometer part is fixed and sealed by the terminal sealing joint, and the wiring terminal is connected to the signal transmission box to complete the installation, which is simple and efficient.

[0015] For temperature cluster detection of large motors, there is no need to redesign the overall structure. Simply adjust the size of the mounting holes of the flange and the terminal sealing joint according to the specifications of the motor temperature mounting position to achieve a suitable installation. It has a wide range of applications. Attached Figure Description

[0019] This application provides an easily replaceable temperature clustering structure, which effectively solves the technical problems of unreliable single-point temperature detection, easy equipment shutdown due to interference, and the need for complete replacement, difficult disassembly and maintenance, long maintenance time, and high spare parts cost of traditional fan bearing and similar large motor temperature clustering devices. Example

[0020] like Figure 1 , Figure 2 As shown, the overall technical solution in this application embodiment is as follows: To address the problems existing in the prior art, this utility model provides an easily replaceable temperature clustering structure. To make the objectives, technical solutions, and advantages of this utility model clearer, the easily replaceable temperature clustering structure described herein will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] This utility model is applicable to a temperature detection cluster device for wind turbine bearings. Its overall structure includes a thermometer part and a mounting flange part. The thermometer part consists of a redundant temperature measuring probe 1, a metal sealing package 4, a signal line armor 5, a protective heat shrink tubing 6, and a needle-shaped wire nose 7. The mounting flange part consists of a flange 2 with the same size and specifications as the original preset temperature mounting position of the wind turbine bearing and a terminal sealing joint 3. The flange 2 is provided with flange fixing screw holes 8 for fixing the flange 2 and mounting holes 9 for installing the terminal sealing joint 3. The mounting holes 9 are machined with internal threads, which are adapted to the external threads on the outside of the terminal sealing joint 3.

[0022] Usage process: Fixing the flange: First, according to the original preset temperature installation position of the fan bearing, install the flange 2 at the original preset temperature installation position of the fan bearing by bolting through the flange fixing screw holes 8. Since the size and specifications of the flange 2 are consistent with the original preset position, there is no need to change the original structure of the fan. After installation, the flange 2 can be stably fitted to the installation position.

[0023] Assembly of terminal sealing joint 3: Select the corresponding number of terminal sealing joints 3 according to the actual number of temperature detection points required by the user. Connect each terminal sealing joint 3 to the internal thread of the mounting hole 9 on the flange 2 through the external thread, and tighten it until the terminal sealing joint 3 and the flange 2 are tightly fitted, thus completing the assembly of the terminal sealing joint 3. If it is necessary to add or remove temperature detection points in the future, it is only necessary to add or remove the number of mounting holes 9 and the appropriate terminal sealing joints 3 accordingly.

[0024] Installation and wiring of the thermometer section: Align the redundant temperature measurement probe 1 with and install it in the temperature detection mounting position provided with the fan, ensuring that the redundant temperature measurement probe 1 can directly contact the bearing detection area to obtain accurate temperature; then insert the metal sealing package 4, which is sleeved on the outside of the signal output end of the redundant temperature measurement probe 1, through the center hole of the terminal sealing joint 3 until the redundant temperature measurement probe 1 is fully adapted to the mounting position. At this time, tighten the sealing component of the terminal sealing joint 3 to fix and seal the metal sealing package 4, preventing external dust and oil from entering the structure and affecting the detection accuracy.

[0025] Signal transmission link setup: After the temperature signal line is led out from the signal output end of the redundant temperature measurement probe 1, it is protected by the signal line armor 5 to prevent the signal line from being damaged by vibration and friction during the operation of the fan. A protective heat shrink tubing 6 is sleeved on the outside of the end of the signal line armor 5 away from the metal sealing package 4 to further enhance the insulation and protection performance of the end of the signal line. Finally, the end of the temperature signal line inside the signal line armor 5 is crimped and fixed to the pin-shaped wire lug 7, and then the pin-shaped wire lug 7 is connected to the user's field signal collection box. The temperature detection signal is then transmitted to the DCS, PLC and other control systems through the field signal collection box to realize real-time monitoring of the fan bearing temperature.

[0026] In actual use, due to the use of redundant temperature measurement probes 1, when one of the redundant temperature measurement probes 1 is damaged or has an abnormal detection, the control system can automatically switch to the other normal redundant temperature measurement probes 1 to obtain the temperature signal without stopping the machine for maintenance. If the damaged temperature detection component needs to be replaced, it is only necessary to loosen the terminal sealing joint 3 at the corresponding position and take out the damaged thermometer part (including redundant temperature measurement probe 1, metal sealing package 4, etc.) for replacement. The other normal thermometer parts and mounting flange parts do not need to be disassembled, which greatly shortens the fan downtime for maintenance and reduces the cost of spare parts replacement.

[0027] Furthermore, when this temperature clustering structure is applied to similar large motor temperature clustering detection applications, it is only necessary to adjust the specifications and dimensions of the flange 2 and mounting hole 9 according to the temperature mounting position dimensions of the large motor to achieve a suitable installation, demonstrating strong adaptability.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
