Description

Technical Field

[0001] This utility model relates to the field of temperature monitoring technology, specifically to a split-type temperature sensor. Background Technology

[0002] In industrial production and equipment monitoring, temperature sensors are widely used to monitor the temperature of various equipment to ensure the safety and stability of equipment operation. Traditional temperature sensors typically employ an integrated structure, with the sensor probe and signal processing unit fixedly connected. This design presents numerous inconveniences during installation and maintenance. For example, in confined spaces or complex operating conditions, the size and rigid connection of the integrated sensor can lead to installation difficulties, sometimes requiring the disassembly of surrounding components, increasing operational complexity and time costs. Furthermore, traditional temperature sensors often require additional fasteners or sealing devices when installed into the temperature measurement port of equipment, not only increasing installation steps but also potentially affecting measurement accuracy due to improper installation. Especially in situations requiring frequent sensor replacement or maintenance, the disassembly and reinstallation process of traditional structures is time-consuming and labor-intensive, reducing work efficiency.

[0041] Example 1

[0042] A split-type temperature sensor, Figure 1 A schematic diagram of the overall structure of one embodiment of the present invention is shown. Figure 2 This is a cross-sectional view of the overall structure of one embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the sensor includes a sensor body 1 and a probe 2. This embodiment of the split-type temperature sensor mainly comprises two parts: the sensor body 1 and the probe 2. The probe 2 is configured with an internal hollow structure and can be a cylinder, housing the temperature-sensing element of the sensor body 1. One end of the probe 2 extends into the temperature-measuring hole of the object to be measured, such as a pipe or equipment housing. A connecting part 210 is provided on the outer wall of the probe 2, through which the probe 2 is connected to the temperature-measuring hole of the object to be measured. The connecting part 210 is located on the outer wall of the probe and can be fixed to the temperature-measuring hole of the object to be measured by means of threads, flanges, clamps, or interference fits. One end of the sensor body 1 is disposed inside the probe 2, and the other end extends out of the probe body along its axial direction.

[0043] A locking part 220 is provided at the end of the probe 2 furthest from the temperature measuring hole, through which the probe 2 is locked to the sensor body. Located at the end of the probe 2, it is used to fix the sensor body 1. The locking part 220 can be threaded, with external threads on the outer wall of the sensor body 1 engaging with the threads on the inner wall of the probe 2; rotation is sufficient to lock it in place. Elastic snap-fit / clamp structures can also be used, applying radial pressure via springs or metal clamps to achieve quick fixation and prevent loosening; magnetic locking, etc.

[0044] The installation steps of this embodiment are as follows: First, the detector 2 is fixed to the temperature measuring hole of the object to be measured through the connecting part 210 (e.g., threaded). Then, the temperature sensing end of the sensor body 1 is inserted axially into the hollow cavity of the detector 2 until it abuts the bottom or a predetermined position. The sensor body 1 and the detector 2 are fixed by the locking part 220 (e.g., rotating thread or pressing buckle) to prevent loosening or falling off.

[0045] Furthermore, in this embodiment, Figure 3 This is a schematic diagram of the detector and inner protective part of one embodiment of the present invention, as shown below. Figure 3 As shown, the connecting part 210 includes a first thread 211 disposed on the outer wall of the detector body, and a second thread disposed on the inner wall of the temperature measuring hole. The first thread 211 and the second thread are compatible. The first thread 211 and the second thread can be metric threads (such as M6, M8), pipe threads (such as G1 / 4", NPT) or other standard threads to meet the needs of different industries. A sealing groove can be added to the root of the first thread 211 and the second thread, such as by wrapping PTFE raw material tape or embedding a metal sealing ring, to enhance the anti-leakage performance, which is especially suitable for temperature measurement of fluid pipelines. The connecting part 210 also includes an operating structure 212, which is sleeved on the outer wall of the detector body 2 and fixedly connected to the detector body 2. The operating structure 212 is sleeved on the outer wall of the detector body 2 and is connected to the detector body 2 by welding, tight fit or screws. The probe 2 is fixed to ensure no relative slippage during torque transmission. The outer wall of the operating structure 212 is equipped with a tool-clamping structure, which includes polygonal prisms, splines, or flat bayonets. Polygonal prisms, such as hexagonal or square heads, are compatible with standard wrenches or socket tools, providing uniform force distribution. Spline structures are suitable for high-torque scenarios (such as the installation of large equipment) and require a dedicated splined wrench. Flat bayonets, such as flathead / Phillips head or internal hexagonal heads, are tightened with a screwdriver or internal hex wrench, saving radial space. Applying torque through the tool-clamping operating structure 212 allows the probe 2 to be easily screwed into the temperature measuring hole, avoiding thread misalignment or poor sealing caused by manual operation.

[0046] Figure 4 This is a schematic diagram of the locking and convergence structure of one embodiment of the present invention; as shown. Figure 3 and Figure 4As shown, the locking part 220 adopts a mechanical convergent locking mechanism. The locking part 220 includes a cutting edge structure 221 and a locking convergent structure 222. The cutting edge structure 221 is fixed to the end of the probe 2 and serves as an actuator for directly clamping the sensor body 1. The locking convergent structure 222 generates axial force through threaded transmission, driving the cutting edge structure to achieve clamping / release.

[0047] The cutting edge structure 221 is disposed at the end of the probe. One end of the cutting edge structure 221 is configured as a first cone surrounded by gaps between several cutting edge components 2211. The cutting edge structure 221 is a multi-lobed cutting edge assembly, consisting of at least three independent cutting edge components 2211 arranged circumferentially. An initial gap is maintained between each cutting edge component to ensure assembly clearance in a free state. One end of the locking and convergence structure 222 is provided with a convergence-promoting structure 2221. The inner wall of the convergence-promoting structure 2221 is configured as a second cone that can promote the convergence of the first cone. The second cone compresses the first cone, causing the gap between the several cutting edge components 2211 to decrease, thereby causing the first cone to close and lock the sensor body. The cone angle of the second cone is slightly smaller than that of the first cone, which can be 1°-2° smaller, allowing for interference fit with the first cone.

[0048] The outer wall of the cutting edge structure 221 near the temperature measuring hole is provided with a third thread 2212, and the inner wall of the locking and converging structure is provided with a fourth thread. The third thread 2212 and the fourth thread are compatible, and the cutting edge structure 221 and the locking and converging structure 222 are locked together by the third thread 2212 and the fourth thread. During installation, the sensor body 1 is inserted into the center hole of the cutting edge structure 221, and each cutting edge 2211 is in a naturally open state. During the locking process, rotating the locking and converging structure 222 generates axial feed, and the second cone and the first cone form a wedge action. The cutting edge 2211 forms a radial displacement to generate clamping force, and the uniform radial force prevents deformation of the sensor body.

[0049] Furthermore, in this embodiment, an inner protective part 3 is also included. The inner protective part 3 is a hollow structure and is disposed inside the detector body 2. The sensor body 1 is disposed inside the inner protective part 3, and the end of the inner protective part 3 away from the temperature measuring hole extends out of the detector body 2. The inner protective part 3 is configured as a flexible protective tube. The inner protective part 3 can prevent the cutting edge structure 221 from pinching and damaging the sensor body 1.

[0050] Furthermore, in this embodiment, it also includes: a wire exit protection part 4; the wire exit protection part 4 is connected to the locking part 220, and the wire exit protection part 4 is used to protect the sensor body 1 located outside the detector body. The wire exit protection part 4 can be configured as a corrugated pipe, or it can be integrally formed with the inner protection part 3.

[0051] Furthermore, this embodiment also includes an optical fiber connector, which is connected to one end of the sensor body extending outside the probe body. The optical fiber connector is used to connect to the adapter cable and back-end equipment. The optical fiber connector can be an FC, ST, SC, or other connectors. Considering the sealing performance, a connector with sealing properties, such as an FC connector, can be used. When the sensor body is not connected to the back end, a dust cap can be placed on it to protect the optical fiber connector.

[0052] This novel temperature sensor features a split design. The probe is first installed separately into the temperature measuring hole of the object to be measured, and then the sensor body is inserted. This design is suitable for confined spaces or complex working conditions, avoiding the difficulties caused by the size limitations of traditional integrated sensors. The connecting part on the outer wall of the probe can be directly fixed to the temperature measuring hole without the need for additional fasteners, simplifying the installation process and improving construction efficiency. The sensor body and the probe adopt a detachable locking structure, reducing assembly stress and maintenance costs.
