Description

Technical Field

[0001] The invention relates to the technical field of temperature transmitter protection, in particular to an anti-interference temperature transmitter with an electromagnetic shielding structure. Background Art

[0002] In modern industrial automation, communication base stations, medical equipment and other fields, temperature transmitters are key measurement and control components, and their accuracy and reliability directly affect the overall performance of the system. With the increase in the number of electronic devices and the complexity of the electromagnetic environment, the problem of electromagnetic interference (EMI) has become increasingly prominent and has become one of the main factors affecting the performance of temperature transmitters. Traditional temperature transmitters often lack effective monitoring and response mechanisms when facing strong electromagnetic interference, resulting in reduced measurement accuracy, equipment malfunctions, and even damage. Therefore, the development of an EMI anti-interference mechanism with self-diagnosis and fault recovery capabilities can significantly improve the stability and reliability of temperature transmitters in complex electromagnetic environments, and has important practical application value.

[0003] The existing Chinese patent with the authorization announcement number CN215374325U discloses a pressure transmitter device capable of shielding electromagnetic interference, including a pressure transmitter, a welding base, a first gap filling area, a pipe, a first reverse magnetic layer and a wrapping layer. A pressure-taking interface is fixedly connected to the middle of the right side of the pipe, and a locking bolt is threadedly connected to the front of the pipe. A front cover mechanism is provided on the top of the pressure transmitter, and a magnetic shielding layer is sleeved on the outer surface of the front cover mechanism. A second gap filling area is fixedly installed at the connection between the pressure transmitter and the magnetic shielding layer. The pressure transmitter device capable of shielding electromagnetic interference is provided with a first gap filling area and a second gap filling area, and a conductive elastic material is filled inside the first filling layer and the filling plate, specifically an electromagnetic sealing gasket, to eliminate non-conductive points and prevent external electromagnetic signals from entering from the non-conductive gaps formed at the junction of different parts of the shielding body, thereby affecting the test results of the pressure transmitter;

[0004] However, since the above-mentioned shielding body surrounds the pressure transmitter as a whole, resulting in air blockage, local heat cannot be dissipated in time during the operation of the transmitter, which can easily affect the working state of the transmitter. For temperature transmitters relying on thermistors, this problem is particularly prominent, which will affect the temperature detection accuracy and produce measurement errors. At the same time, the electromagnetic shielding structure and fluidity themselves have certain contradictions. How to make different degrees of switch adjustments according to different scenarios is also a technical problem that needs to be solved urgently. Summary of the invention

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1

[0039] Reference Figures 1 to 8 , which is the first embodiment of the present invention. This embodiment provides an anti-interference temperature transmitter with an electromagnetic shielding structure, including a shell 100, a temperature measuring element 101 and a transmitter module 102, an isolation structure and an adjustment mechanism. The isolation plate 202 is switched with the two flow channel grooves respectively to achieve the switching of coolant circulation cooling and electromagnetic shielding state while achieving positioning buffering of the transmitter module 102, and the measurement accuracy is reduced due to vibration dislocation.

[0040] Specifically, it includes: a housing 100;

[0041] A temperature measuring element 101 and a transmitter module 102, wherein the temperature measuring element 101 is disposed outside the housing 100, and the transmitter module 102 is disposed inside the housing 100 and one end of the transmitter module 102 extends to the outside of the housing 100 to be connected to the temperature measuring element 101;

[0042] The isolation mechanism comprises a first sealing cylinder 200 and a second sealing cylinder 201 respectively arranged between the transmitter module 102 and the housing 100, an isolation plate 202 is movably arranged between the first sealing cylinder 200 and the second sealing cylinder 201, a plurality of isolation plates 202 are arranged in an array and are embedded with the first sealing cylinder 200 to form a complete cylinder when they are arranged close to each other, and are embedded with the second sealing cylinder 201 to form a complete cylinder when they are distributed dispersedly;

[0043] The adjustment mechanism includes a swing arm 300 rotatably disposed on the upper end surface of the isolation plate 202. The swing arms 300 are rotatably connected and when the isolation plates 202 are close to each other, the two ends of the swing arms 300 respectively contact and fit the inner wall of the housing 100 and the transmitter module 102.

[0044] Among them, a first flow channel 1001 is opened on the first sealing cylinder 200 close to the inner wall of the shell 100, and a second flow channel 1002 is opened on the second sealing cylinder 201 close to the transmitter module 102. The isolation plate 202 is arranged parallel to the first flow channel 1001 and the second flow channel 1002 and can be respectively embedded.

[0045] Preferably, in this embodiment, the isolation plate 202 and the first flow channel groove 1001 and the second flow channel groove 1002 are each provided with 7 and the outer shape is waist-shaped, so that when the isolation plate 202 and each flow channel groove are simultaneously engaged, a complete cylinder is formed to play an electromagnetic isolation and shielding function.

[0046] More preferably, the transmitter module 102 is provided with a signal transmission tube 1003 , which passes through the first sealing tube 200 and the second sealing tube 201 , and a connecting block 1004 is provided at one end of the signal transmission tube 1003 of the first sealing tube 200 and the second sealing tube 201 .

[0047] More preferably, the first flow channel 1001 is set with the connecting block 1004 as the starting point, and the spacing between each first flow channel 1001 is the spacing when the isolation plates 202 are closely distributed. The second flow channel 1002 is set with the connecting block 1004 as the starting point and the spacing when the isolation plates 202 are dispersedly distributed.

[0048] The isolation plate 202 is rotatably arranged at the midpoint of the swing arm 300 , and swivels 1005 are arranged at both ends of the swing arm 300 . The swing arm 300 is rotatably connected to other swing arms 300 and the connecting block 1004 via the swivels 1005 .

[0049] Among them, the swing arm 300 farthest from the connecting block 1004 is also rotatably connected to the isolation plate 202 through the swivel 1005. When the swing arm 300 slides clockwise between the first sealing cylinder 200 and the second sealing cylinder 201, it drives each rotatably connected swing arm 300 to unfold, so that the isolation plate 202 and the second flow channel groove 1002 are embedded and sealed to form a complete shielding cylinder, otherwise it is embedded and sealed with the first flow channel groove 1001 to form an outer shielding cylinder.

[0050] Furthermore, a mounting post 1006 is movably provided on the outer wall of the transmitter module 102 , and the mounting post 1006 is detachably embedded in the inner wall end surface of the housing 100 .

[0051] Among them, in this embodiment, the mounting column 1006 rotates and passes through the shell 100, the mounting column 1006 is sealed and connected to the shell 100, the transmitter module 102 adopts a waterproof design, and the coolant is filled between the transmitter module 102 and the shell 100 to transfer the heat generated by the transmitter module 102 to the shell 100 for dissipation. The coolant has a certain conductive effect, so it is always filled into the first flow channel 1001 and the second flow channel 1002 to maintain the overall current conduction effect, thereby ensuring the magnetic shielding effect.

[0052] More preferably, two sets of connecting blocks 1004 are symmetrically provided, and rubber buffer pads are provided on the periphery of the rotating ring 1005, which respectively fit with the inner wall of the shell 100 and the mounting column 1006 when the swing arm 300 is bent and folded, thereby achieving fixed buffering of the transmitter module 102 and the shell 100.

[0053] Among them, the two sets of swing arms 300 are used to fix and buffer two points on the outer wall of the transmitter module 102 through the interference, and buffer is performed when experiencing large-scale vibration, so as to avoid the reduction of measurement accuracy caused by vibration dislocation of the internal transmitter module 102 and the temperature measuring element 101.

[0054] In other embodiments, the connection blocks 1004 may be provided with three or four sets in a circular array to increase the number of fixed buffering fulcrums, thereby improving the fixed buffering effect on the transmitter module 102 .

[0055] In summary, when in use, in the initial state, each isolation plate 202 is sealed and engaged with the first flow channel 1001 on the first sealing cylinder 200, thereby forming a complete cylinder to perform electromagnetic impact on the transmitter module 102 to prevent external electromagnetic interference. When the transmitter module 102 is locally heated and the coolant cannot be transmitted to the shell 100 due to isolation by the cylinder, the mounting post 1006 is rotated clockwise. At this time, the swing arm 300 is bent and contacts and fits with the mounting post 1006, thereby driving the swing arm 300 to rotate clockwise, and the isolation plate 202 is separated from the first flow channel 1001, and the first flow channel 1001 is connected to the second flow channel 1002. In addition, due to the movement of the isolation plate 202, the internal liquid flows, and the coolant with a higher temperature is transmitted to the inner wall of the shell 100 for heat dissipation more quickly.

[0056] At the same time, when the transmitter module 102 needs to be repaired, the swing arm 300 farthest from the connecting block 1004 is rotated so that each swing arm 300 rotates clockwise and unfolds, and at the same time drives the isolation plate 202 to disengage from the first flow channel groove 1001 and engage with the second flow channel groove 1002, so that most of the coolant is sealed and isolated between the second sealing cylinder 201 and the inner wall of the shell 100, reducing leakage during disassembly and facilitating maintenance. At the same time, the swing arm 300 and the swivel 1005 will release the limit of the mounting column 1006, making it convenient for disassembly. During the later installation, the mounting column 1006 can be assisted in positioning by the swivel 1005 and the swing arm 300.

[0057] Example 2

[0058] Reference Figures 1 to 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the end face of the transmitter module 102 is further protected by the fan-shaped piece 2003 to improve the overall electromagnetic shielding effect. At the same time, the fan-shaped piece 2003 is rotated after being deflected at an angle to make the coolant flow faster, thereby improving the heat dissipation effect.

[0059] Specifically, a positioning cylinder 2001 is fixedly provided on the outer wall of the mounting column 1006 , and the rotating ring 1005 is respectively pressed against the outer wall of the positioning cylinder 2001 and the inner wall of the housing 100 , and a fan-shaped groove 2005 is provided in a circumferential array on the inner wall of the bottom surface of the positioning cylinder 2001 .

[0060] The outer wall of the mounting column 1006 is also rotatably provided with a first circular sleeve 2002 , the outer wall of the first circular sleeve 2002 is rotatably provided with a sector piece 2003 , and the other end of the sector piece 2003 is rotatably provided with a second circular sleeve 2004 .

[0061] Among them, the first circular sleeve 2002 and the second circular sleeve 2004 are both hollow circular sleeves and are coaxially arranged. In this embodiment, the fan-shaped sheets 2003 and the fan-shaped grooves 2005 are each provided with seven pieces and overlap with the surfaces of each fan-shaped groove 2005 when laid together, so as to surround and protect the vertical end face of the transmitter module 102, thereby improving the overall shielding effect and improving the anti-interference ability of the temperature transmitter.

[0062] The outer wall of the second circular sleeve 2004 is also rotatably provided with an adjustment sleeve 2006 , and a rotating shaft 2007 is fixedly provided at the center of the sector piece 2003 . The rotating shaft 2007 rotatably penetrates the outer wall of the second circular sleeve 2004 and is fixedly connected to the adjustment sleeve 2006 .

[0063] More preferably, a slide groove 2008 is formed on the adjustment sleeve 2006 , a driving ring 2009 is rotatably provided on the outer wall of the second circular sleeve 2004 , a sliding column 2011 is provided on the outer wall of the driving ring 2009 , and the sliding column 2011 is slidably sleeved in the slide groove 2008 .

[0064] Furthermore, the slide groove 2008 is arranged in parallel with the adjustment sleeve 2006. When the slide column 2011 rotates, the adjustment sleeve 2006 is driven to rotate through the slide groove 2008, so that the rotation shaft 2007 rotates to drive the fan-shaped piece 2003 to flip, thereby leaving the overlapping position with the fan-shaped groove 2005 and forming a certain angle.

[0065] The inner wall of the driving ring 2009 is rotatably engaged with a driving shaft 2012 , and the driving shaft 2012 is controlled by a micro motor to rotate in positive and negative directions. A connecting plate 2013 is also provided on the lower end surface of the driving ring 2009 .

[0066] More preferably, a limit slot 2014 is provided in parallel on the connecting plate 2013 , the rotating shaft 2007 movably passes through the limit slot 2014 , and a rotating column 2015 is rotatably provided on a rotating ring 1005 directly connecting the swing arm 300 and the isolation plate 202 .

[0067] Among them, the rotating column 2015 is fixedly connected to the connecting plate 2013. When the driving shaft 2012 drives the driving ring 2009 to rotate, it will drive the rotating ring 1005 and the isolation plate 202 there to rotate through the connecting plate 2013 and the rotating column 2015, so that each isolation plate 202 rotates as a whole under its drive.

[0068] More preferably, when the fan-shaped piece 2003 forms an angle with the fan-shaped groove 2005, the first circular sleeve 2002 and the fan-shaped piece 2003 rotate under the drive of the driving ring 2009, which will disturb the internally filled coolant, accelerate the internal flow, and improve the cooling effect.

[0069] In summary, in the initial state, the sector piece 2003 overlaps with the sector groove 2005 to form a shielding layer, which performs electromagnetic shielding on the vertical end face of the transmitter module 102. When the transmitter module 102 is locally overheated, the micro motor is controlled to drive the drive shaft 2012 to rotate clockwise, thereby driving the drive ring 2009 to rotate clockwise, and driving the slide groove 2008 to swing to the left through the slide column 2011, and the rotating shaft 2007 rotates to make the sector piece 2003 deviate from the horizontal angle.

[0070] At the same time, as the driving ring 2009 continues to rotate, the slide groove 2008 swings to the maximum angle and drives the swing arm 300 to rotate through the connecting plate 2013, thereby realizing the connection between the first flow channel groove 1001 and the second flow channel groove 1002. At the same time, the limiting groove 2014 on the connecting plate 2013 drives the first circular sleeve 2002 and the second circular sleeve 2004 to rotate. The inclined fan-shaped piece 2003 allows the internal coolant to flow in one direction during rotation, thereby accelerating the heat dissipation efficiency and allowing the internal coolant to be conducted to the inner wall of the shell 100 faster.

[0071] Example 3

[0072] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention, is based on the previous embodiment, but differs in that the requirements of electromagnetic shielding and heat dissipation are coordinated through a high-intensity anti-interference system, and heat is dissipated without affecting the electromagnetic shielding effect through two different modes of micro-motor driving.

[0073] Specifically, it also includes a high-intensity anti-interference system, which includes a detection module and an adjustment module. The detection module is used to detect the distribution of electromagnetic waves outside the shell 100 and the temperature distribution in the transmitter module 102, and the adjustment module is used to control the rotation direction and speed of the micro motor.

[0074] The detection module includes an electromagnetic field monitoring unit disposed on the outer walls of the four sides of the shell 100, which is used to monitor the electromagnetic distribution intensity around the shell 100 and record and transmit it to the adjustment module.

[0075] More preferably, the detection module also includes a temperature monitoring unit arrayed on the outer wall of the transmitter module 102, and the temperature monitoring unit is used to measure the temperature of various locations on the outer wall of the transmitter module 102. When the temperature value exceeds the set threshold of the temperature transmitter, a cooling instruction is generated and transmitted to the adjustment module.

[0076] Furthermore, the adjustment module receives electromagnetic distribution intensity information, and determines whether electromagnetic shielding is required in combination with an electromagnetic interference setting threshold. The adjustment module also includes an execution unit. When the adjustment module determines that electromagnetic shielding is required, the execution unit controls the micromotor to rotate until each isolation plate 202 is sealed and engaged with the first flow channel groove 1001, thereby forming a complete metal cylinder for electromagnetic shielding protection.

[0077] Among them, the adjustment module also includes an adjustment unit. After receiving the cooling instruction, the adjustment unit first obtains the electromagnetic shielding state. When electromagnetic shielding protection is not performed, the micro motor is controlled to rotate unidirectionally to the isolation plate 202 and the second flow channel groove 1002, and the coolant is circulated and cooled by rotating the fan-shaped piece 2003 at the same time, and then the micro motor is controlled to rotate reciprocatingly at a set frequency until the temperature value is lower than the set threshold.

[0078] More preferably, when electromagnetic shielding protection is performed, the micro motor is controlled to reciprocate in a set small amplitude and low frequency manner, so as to reduce the temperature without affecting the electromagnetic shielding effect, thereby ensuring the normal operation of the temperature transmitter.
