Description

Technical Field

[0001] This invention relates to the field of temperature pulsation meter probe technology, specifically to a modular temperature pulsation meter probe. Background Technology

[0002] With the rapid development of high-tech industries both domestically and internationally, optoelectronic technology is increasingly widely used in modern industry, placing higher demands on the propagation characteristics of light in the atmosphere for many optoelectronic devices. In the atmospheric medium, dust particles and other particles cause light scattering, while atmospheric turbulence can lead to phenomena such as beam drift, broadening, flickering, and intensity fluctuations, thus affecting the operational stability of optoelectronic devices. Therefore, how to quickly and accurately collect and analyze atmospheric turbulence conditions has become a crucial foundation for ensuring the normal operation of related optoelectronic devices.

[0003] Atmospheric turbulence is typically accompanied by disturbances in the fluid medium, resulting in temperature fluctuations at different spatial locations within the medium over time. Based on this, parameters related to atmospheric turbulence can be obtained by measuring and analyzing temperature changes at different locations. Temperature pulsation meters are a type of equipment used for such measurements and analyses. They typically use multiple temperature probes to measure the temperature at different locations within the atmospheric medium and combine the data processing to obtain relevant indicators characterizing atmospheric turbulence.

[0004] However, existing temperature pulsation meters mostly use small-diameter platinum wires as sensing elements. These platinum wires are typically installed on the temperature probe and exposed to the atmosphere for extended periods. Because platinum wires have low strength and are easily affected by external disturbances, they are prone to damage under long-term operating conditions. Furthermore, the methods for leading out, laying out, and fixing the platinum wires in existing temperature pulsation meter probes are inconsistent. Additionally, the replacement and adjustment of the platinum wires are often cumbersome, affecting the continuous operation and maintenance efficiency of the equipment, thus limiting the stability and reliability of the temperature pulsation meter. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art, thereby providing a modular temperature pulsation instrument temperature probe.

[0006] A modular temperature pulsator probe includes a connecting cylinder, a threaded groove cylinder, a fixing component, a fixing component support, and a lower connecting plate. The lower connecting plate is connected to the threaded grooved cylinder, which is provided with a spiral guide structure; the top of the threaded grooved cylinder is connected to the fixed component support, which is provided with a fixed component. The connecting cylinder is inserted into the threaded groove cylinder from the lower connecting plate and is positioned and engaged with the threaded groove cylinder; a first conductor and a second conductor are provided inside the connecting cylinder; one end of the platinum wire is connected to the first conductor, and extends to the outside through the connecting through hole on the side wall of the threaded groove cylinder and is wound along the spiral guide structure. The fixing component clamps one end of the platinum wire, and the other end of the platinum wire extends from the through hole provided on the fixing component support to the inside of the threaded groove cylinder and is connected to the second conductor.

[0007] Furthermore, the fixing component support includes a base, a support platform, and a fixing component protective component; The two sides of the support platform are connected to the base platform and the fixed component protective member, respectively. The base platform is inserted into the top of the threaded groove cylinder and positioned. The fixed component protective member has a ring structure and the fixed component is set inside the fixed component protective member.

[0008] Furthermore, the through hole extends through the base platform and the support platform.

[0009] Furthermore, the support platform is an annular platform, and the outer diameter of the support platform is adapted to the outer diameter of the threaded groove cylinder.

[0010] Furthermore, the base platform is a cylindrical structure, and the center of the base platform is coaxial with the center of the support platform and the threaded groove cylinder.

[0011] Furthermore, the protective component of the fixing assembly is not coaxial with the center of the support platform.

[0012] Furthermore, the fixing component includes a resilient clamping fork.

[0013] Furthermore, the elastic clamping fork has a pair of opposing clamping arms, with a clamping opening for clamping the platinum wire formed between the two clamping arms.

[0014] Furthermore, the clamping opening is specifically a V-shaped clamping opening that gradually narrows from the outer end to the inner end along the length direction of the elastic clamping fork.

[0015] Furthermore, the modular temperature pulsator probe also includes an upper connecting plate and multiple support rods, with the two ends of the multiple support rods connected to the upper connecting plate and the lower connecting plate, respectively.

[0016] The technical solution of this invention has the following advantages: 1. Clear assembly path and high assembly consistency: The platinum wire is led out through the connecting through hole to the outside of the threaded groove cylinder and wound along the spiral guide structure. It is then clamped and fixed by the fixing component. At the same time, the other end of the platinum wire is led back through the through hole to the inside of the threaded groove cylinder and connected to the second wire. This makes the lead-out, guiding, fixing and return connection path of the platinum wire clear, which facilitates a consistent assembly process.

[0017] 2. Reliable connection and stable fixation: The fixing component is set on the fixing component support, and the fixing component support is positioned by inserting the base into the top of the threaded groove cylinder; the V-shaped clamping port of the elastic clamping fork provides clamping and fixing for the platinum wire, which is conducive to the stability of the platinum wire connection position.

[0018] 3. Good protection and improved resistance to external interference: The protective component of the fixing component is a ring structure that surrounds the fixing component to form a protective space, which can reduce the impact of external touch and collision on the platinum wire clamping area.

[0019] 4. Reasonable wiring and spatial layout: Through holes pass through the base and support platform to facilitate the return and threading of the platinum wire end; with the structural configuration of the fixed component protective part and the support platform having different axes, an offset wiring channel can be formed, which facilitates the connection and layout of the platinum wire and the internal conductor.

Detailed Implementation

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1-3 As shown, the present invention provides a modular temperature pulsation probe, comprising a connecting cylinder 1, a threaded grooved cylinder 3, a fixing component 5, a fixing component support 6, and a lower connecting plate 8. The lower connecting plate 8 is connected to the threaded grooved cylinder 3, which has a spiral guide structure for guiding and limiting the external winding of the platinum wire. The top of the threaded grooved cylinder 3 is connected to the fixing component support 6, and the fixing component 5 is mounted on the fixing component support 6 for clamping and fixing a section of the platinum wire.

[0028] The lower connecting plate 8 and the threaded grooved cylinder 3 are preferably assembled and positioned using a snap-fit ​​connection. Specifically, the lower connecting plate 8 may be provided with a snap-fit ​​part, and the lower end of the threaded grooved cylinder 3 may be provided with a groove part that mates with the snap-fit ​​part. During assembly, after the threaded grooved cylinder 3 is pressed into place relative to the lower connecting plate 8, the snap-fit ​​part and the groove part engage to form an axial limit, thereby ensuring a reliable connection between the lower connecting plate 8 and the threaded grooved cylinder 3. To further improve assembly consistency, an annular limiting step or positioning surface may be provided between the lower connecting plate 8 and the threaded grooved cylinder 3 to limit the assembly depth and coaxiality of the threaded grooved cylinder 3.

[0029] The above structure can stably limit the position and orientation of the threaded groove cylinder 3, thereby providing a stable structural foundation for the platinum wire to be wound and laid along the spiral guide structure.

[0030] The connecting cylinder 1 is inserted into the threaded groove cylinder 3 from the lower connecting plate 8 and is positioned and engaged with the threaded groove cylinder 3. Preferably, an insertion positioning cavity is formed on the inner side of the threaded groove cylinder 3, and a positioning outer diameter adapted to the insertion positioning cavity is formed on the outer side of the connecting cylinder 1, thus forming radial positioning after the connecting cylinder 1 is inserted. More preferably, a limiting step is provided on the connecting cylinder 1 or the threaded groove cylinder 3. After the connecting cylinder 1 is inserted into place, the limiting step achieves axial limiting, thereby limiting the insertion depth of the connecting cylinder 1 inside the threaded groove cylinder 3 and ensuring the consistency of the internal spatial dimensional chain.

[0031] The connecting cylinder 1 is provided with a first wire 2 and a second wire 9. The first wire 2 and the second wire 9 are connected to the first terminal 10 and the second terminal 11 respectively. The first terminal 10 and the second terminal 11 can be used to connect to the main body of the temperature pulsator and transmit the temperature signal detected by the platinum wire to the main body of the temperature pulsator. The first wire 2 and the second wire 9 are set inside the threaded groove cylinder 3 and are not exposed to the outside, reducing the risk of entanglement interference or pulling damage caused by exposed wires.

[0032] After one end of the platinum wire is connected to the first conductor 2, it extends to the outside of the threaded groove cylinder 3 through the connecting through hole 301 on the side wall of the threaded groove cylinder 3. The connecting through hole 301 is preferably located in the side wall area of ​​the threaded groove cylinder 3 near the lower connecting plate 8, so that the platinum wire can be led out from the inside and wound upward along the spiral guide structure on the outside of the threaded groove cylinder 3.

[0033] The spiral guide structure on the threaded grooved cylinder 3 is preferably either a spiral groove or a spiral rib, used to limit the winding path and pitch of the platinum wire, avoiding crossing, skipping, or uneven tension during the winding process, thereby improving assembly consistency. After the platinum wire is wound along the spiral guide structure to the top of the threaded grooved cylinder 3, a section of the platinum wire is clamped by the fixing component 5 to achieve stable fixation of the platinum wire at the top position.

[0034] In one embodiment, the fixing component 5 includes an elastic clamping fork 501. The elastic clamping fork 501 has a pair of opposing clamping arms, with a clamping opening for clamping the platinum wire formed between the two clamping arms. The clamping opening gradually narrows from the outer end to the inner end along the length direction of the elastic clamping fork 501, forming a V-shaped clamping opening. During assembly, one end of the platinum wire is pressed into the V-shaped clamping opening, and the elastic clamping fork 501 clamps and fixes the platinum wire, making the top clamping position clear and facilitating consistent assembly operations. The size of the V-shaped clamping opening is slightly smaller than the diameter of the platinum wire. By clamping and positioning one end of the platinum wire with the elastic clamping fork 501, the exposed length of the platinum wire and the winding tension along the spiral guide structure on the threaded groove cylinder 3 can be adjusted before the other end of the platinum wire is connected to the second wire 9. This helps to ensure that the effective length of the platinum wire participating in temperature measurement is consistent in different temperature measuring probes, improving probe assembly consistency and measurement consistency.

[0035] like Figures 4-5 As shown, the fixing component support 6 includes a base 601, a support platform 602, and a fixing component protective member 603. The two sides of the support platform 602 are connected to the base 601 and the fixing component protective member 603, respectively. The fixing component protective member 603 has a ring structure, and the fixing component 5 is disposed inside the fixing component protective member 603, so that the fixing component 5 is within the space formed by the ring structure, thereby reducing the possibility of direct external contact with the fixing component 5 and its clamping area, and improving the protection and stability of the top clamping area.

[0036] The base 601 is inserted into the top of the threaded groove cylinder 3, preferably using an insertion fit and axial positioning achieved through a limiting step. In a preferred embodiment, the base 601 is a cylindrical structure, and the center of the base 601, the support platform 602, and the threaded groove cylinder 3 are coaxial, ensuring a stable coaxial positioning relationship when the base 601 is inserted into the top of the threaded groove cylinder 3. The support platform 602 is preferably an annular platform, and the diameter of the support platform 602 is adapted to the outer diameter of the threaded groove cylinder 3, so that the fixing component support 6 and the top of the threaded groove cylinder 3 form a matching assembly shape and improve the stability of the top structure.

[0037] A through-hole 604 is provided on the fixing component support 6 and extends through the base 601 and the support platform 602. The other end of the platinum wire extends from the through-hole 604 into the interior of the threaded groove cylinder 3 and connects to the second conductor 9, thus forming a clear path of "internal connection - external winding - top clamping - return internal connection". The through-hole 604 is preferably set as an eccentric hole so that the wiring path of the through-hole 604 is spatially offset from the installation area of ​​the fixing component 5, thereby providing a more reasonable arrangement space for the installation of the fixing component 5, the return threading of the platinum wire, and the internal conductor connection, and reducing the possibility of assembly interference.

[0038] like Figures 1-3As shown, in another embodiment, the temperature probe further includes an upper connecting plate 4 and multiple support rods 7, with both ends of the multiple support rods 7 connected to the upper connecting plate 4 and the lower connecting plate 8, respectively. The multiple support rods 7 are preferably distributed circumferentially, forming a frame structure through the upper connecting plate 4 and the lower connecting plate 8, thereby constraining the relative positions of the threaded groove cylinder 3 and the connecting cylinder 1, making the overall probe structure more stable, and further improving assembly consistency and connection reliability.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
