Description

TECHNICAL FIELD

[0001] The composite sensor relates to a high-temperature-resistant temperature and vibration composite sensor applied to the field of measuring tests. BACKGROUND

[0002] The temperature vibration sensor is a device specially used for measuring the running state of rotating machinery, including vibration speed, vibration displacement, device surface temperature, vibration frequency, etc., and is suitable for online measurement of temperature and vibration of rotating devices such as motors, speed reducers, fans, generators, air compressors, centrifuges and water pumps. When the temperature vibration sensor is applied, the bolt connection and magnetic attraction connection are generally used, and the stability of the two connection modes is poor, which will cause displacement under the action of vibration, causing poor contact between the temperature vibration sensor and the detection surface, thereby reducing the monitoring accuracy in the subsequent application process.

[0003] In order to solve the problem of displacement of the temperature vibration sensor caused by vibration, some temperature vibration sensors in the market use adhesive design, which has a certain market share.

[0004] The specification of Chinese invention patent CN118347542A discloses a high anti-electromagnetic interference vibration temperature composite sensor, the base is fixed by smearing adhesive, the shell is inserted into the base and rotated clockwise, the clamping block is slid outwardly under the action of the arc plate and the clamping teeth, and under the action of the transmission assembly, the sliding plate moves downward while driving the detection assembly to move downward, until the detection assembly is close to the surface to be detected. When maintenance or disassembly is needed, only the knob needs to be rotated, so that the contact head is separated from the sliding plate, and then the sliding plate can continue to move downward, that is, the shell continues to rotate clockwise, until the limiting block corresponds to the access slot, and the shell can be disassembled, realizing the close installation of the sensor and the convenient maintenance and disassembly, and the structure is simple and the operation is simple.

[0005] The above-mentioned technology effectively solves the problem of displacement of the temperature vibration sensor caused by vibration, and further generates monitoring error, but in the application process of the temperature vibration sensor, the application environment has diversity.

At the same time, the heat protection of the internal environment of the composite sensor body 1 can also be effectively realized, further reducing the influence of heat on the internal components of the composite sensor body 1 and enhancing the heat resistance of the composite sensor body 1. In addition, through the setting of the early warning unit, the warning function of the overheated environment can be realized, which not only helps to improve the effectiveness and safety of the application of the composite sensor body 1, but also ensures the timeliness and effectiveness of the subsequent emergency response. Moreover, the transmission of the early warning data and the monitoring data of the composite sensor body 1 can form a mutual verification and corresponding relationship to ensure the accuracy and reliability of the data monitoring and early warning data.

[0022] Figure 1 - Figure 3 and Figure 7 The transmission vibration space 12 is fixedly connected with a plurality of air exhaust fan groups 6 on the inner wall of the side wall, the air exhaust fan group 6 comprises an air exhaust cylinder fixedly installed on the inner wall of the transmission vibration space 12, the lower end of the air exhaust cylinder is in an open shape, a plurality of micro fans 61 are fixedly installed in the air exhaust cylinder, the output end of the air exchange control unit is signal connected with the micro fan 61, and the micro fan 61 and the air exchange control unit are arranged.

[0023] Figure 1 - Figure 3 、 Figure 5 and Figure 7The heat exchange cavity is provided with a waterproof layer or an oil separation layer on the inner wall. The upper end of the air extraction cylinder is connected to the upper end of the heat exchange cavity through a heat exchange pipe. The heat exchange cavity is fixedly connected with a sealing isolation ring 41 at the middle part of the inner side. The heat exchange cavity is filled with heat exchange liquid 42 located below the sealing isolation ring 41. The heat exchange liquid 42 can be water, coolant, cooling oil or other liquid capable of heat exchange. The heat exchange liquid 42 can improve the heat exchange effectiveness and maintain the elastic effect of the temperature insulation sleeve 4. The weight of the heat exchange liquid 42 is insufficient to overcome the elastic contraction force of the temperature insulation sleeve 4. The heat exchange liquid 42 can exchange heat with the gas in the composite sensor body 1 while the air regulating unit regulates the temperature of the composite sensor body 1, thereby improving the temperature control effect of the composite sensor body 1 and reducing the thermal damage to the composite circuit board 2 and the vibration element 16 caused by high temperature.

[0024] Figure 1 Figure 3 Figure 7 Figure 10 The composite sensor body 1 is fixedly connected with a mounting head 14 at the lower end. The upper end of the mounting head 14 extends into the temperature sensing space 11 and is fixedly connected with the temperature sensing element 13. The upper end of the mounting head 14 is fixedly connected with a vibration transmission rod. The upper end of the vibration transmission rod penetrates through the temperature sensing element 13 and the vibration element 16 and is fixedly connected with the inner wall of the vibration transmission space 12. The temperature sensing element 13 and the vibration element 16 are separately arranged. The temperature sensing element 13 can effectively improve the monitoring data reliability and effectiveness. After subsequent temperature rise, the high temperature is not directly applied to the vibration element 16, thereby reducing the thermal damage of the internal structure of the vibration element 16 and improving the monitoring accuracy of the temperature sensing element 13 and the vibration element 16 in the application process, thereby ensuring the continuous reliability of the data.

[0025] ​​​It should be noted that the temperature sensing element 13 and the vibration element 16 are existing structures, which are directly quoted here without any changes to their structure and principle. Those skilled in the art can select the specific structure according to the actual situation, for example: the temperature sensing element 13 can be a thermocouple: the temperature value is obtained by measuring the thermoelectric potential generated by two different metal materials under temperature difference; or a thermistor: the resistance value changes with temperature; or an infrared sensor: the temperature is determined by receiving the infrared radiation energy of the surface of the object. The vibration element 16 can be a piezoelectric acceleration sensor: using piezoelectric effect, when the sensor is subjected to vibration acceleration, the internal piezoelectric material will generate electric charge, and the vibration acceleration information is obtained by measuring the charge; or a strain gauge sensor: the strain gauge is pasted on the elastic element, when the elastic element deforms with vibration, the resistance value of the strain gauge changes, so as to detect the vibration by measuring the resistance change; or a capacitive sensor: the capacitor is composed of fixed electrode and movable electrode, when the electrode spacing or area changes due to vibration, the capacitance value changes, and the vibration information is obtained by measuring the capacitance change. Therefore, no more details are given here.

[0026] Figure 1 Figure 3 Figure 7 Figure 10 The output end of the composite monitoring processing unit is also connected with a monitoring data transmission unit, the output end of the monitoring data transmission unit is signal connected with the signal branch 15 fixedly arranged at the left end of the composite sensor body 1, the wireless connection of the signal branch 15 can be realized by using local area network or wireless communication technology, the signal branch 15 is wirelessly connected with a maintenance platform, which can transmit the data of the composite sensor body 1 to the maintenance platform, display the monitoring data to the staff and issue early warning reminders, the maintenance platform is provided with a display and an alarm cooperating with the signal branch 15, and the maintenance platform can also be signal connected with the PC end and the mobile end of the staff, realizing the transmission of the data of the composite sensor body 1, ensuring that the staff can effectively obtain the monitoring data and the early warning data, the setting of the monitoring data transmission unit can effectively realize the transmission of the monitoring data and the abnormal data of the composite sensor body 1, ensuring the monitoring effect of the composite sensor body 1, and also effectively transmitting the data of the state of the composite sensor body 1, thereby effectively improving the reliability of the application of the composite sensor body 1.

[0027] Figure 1 Figure 3 Figure 5 Figure 7 Figure 10 ​​​​​​​After the composite sensor body 1 is applied by being installed on the monitoring object through the mounting head 14, the temperature data of the monitoring object is collected by the temperature sensing element 13, and then the temperature data is transmitted to the composite monitoring processing unit through the temperature monitoring unit. The vibration generated by the monitoring object is transmitted to the vibration element 16 through the mounting head 14, the composite sensor body 1, the temperature sensing element 13, and the vibration transmission rod. The vibration data of the monitoring object is transmitted to the composite monitoring processing unit through the vibration monitoring unit. Then, after the composite monitoring processing unit processes the received data, the temperature data and the vibration data of the monitoring object are output to the maintenance platform through the cooperation of the monitoring data transmission unit and the signal support rod 15. The worker can observe the data of the monitoring object in real time through the maintenance platform to effectively realize the observation of the running stability of the monitoring object.

[0028] In the application process of the monitoring object, when the temperature of the monitoring object or the environment of the monitoring object continuously rises, the composite monitoring processing unit obtains the temperature data transmitted by the temperature sensing element 13 through the temperature monitoring unit, judges that the temperature is high and needs to protect the composite sensor body 1, and then transmits the control data to the ventilation control unit to control the micro fan 61 in the exhaust fan group 6 to start working, so as to exhaust the gas in the transmission vibration space 12 and transport it to the heat exchange cavity of the temperature isolation sleeve 4. The gas continuously entering the heat exchange cavity will produce a downward pressure on the sealing isolation ring 41, so that the sealing isolation ring 41 drives the upper half of the temperature isolation sleeve 4 to deform downward, and drives the magnetic induction ring 5 to move downward continuously, thereby effectively reducing the air content in the transmission vibration space 12 and reducing the heat conduction efficiency in the transmission vibration space 12, thereby achieving the effect of pressure reduction and temperature isolation. After the temperature isolation sleeve 4 is elongated and deformed to move the magnetic induction ring 5 to abut against the lower shell 31, the temperature isolation protection feedback unit receives the trigger signal of the magnetic induction ring 5, and then feeds back the signal to the composite monitoring processing unit. The composite monitoring processing unit judges and processes the feedback signal, and then transmits the holding instruction to the temperature isolation holding unit. The temperature isolation holding unit controls the electromagnetic adsorption ring embedded in the lower shell 31 to be electrified to generate magnetism and adsorb the magnetic induction ring 5, thereby fixing the position of the magnetic induction ring 5, so as to realize the continuous temperature isolation of the composite sensor body 1 by the temperature isolation sleeve 4.

[0029] Then, the composite monitoring processing unit continues to acquire and judge the temperature data and vibration data of the monitoring object according to the data transmitted by the temperature monitoring unit and the vibration monitoring unit, judges the state of the monitoring object at this time, and after judging that the temperature of the monitoring object no longer rises and gradually returns to normal, the composite monitoring processing unit cuts off the current input to the electromagnetic adsorption ring through the temperature insulation maintaining unit, releases the adsorption and fixation of the magnetic induction ring 5, and then controls the micro fan 61 to close through the air exchange control unit. The gas in the heat exchange cavity continuously enters the transmission vibration space 12 under the action of pressure self-balancing through the air extraction fan group 6, the decompression effect of the transmission vibration space 12 at this time is released, the damage of the composite circuit board 2 caused by continuous decompression is avoided, and the upper half of the temperature insulation sleeve 4 continuously generates shrinkage recovery deformation, improves the efficiency of the gas in the heat exchange cavity entering the transmission vibration space 12, and resets the temperature insulation sleeve 4. The composite monitoring processing unit also transmits the temperature data, vibration data and temperature change data of the monitoring object to the maintenance platform through the cooperation of the monitoring data transmission unit and the signal support rod 15, and displays the state of the monitoring object and the state of the environment where the monitoring object is located to the staff in time, so as to facilitate the staff to check and analyze the temperature rising factors, ensure the stability of the subsequent monitoring object operation, and promote the effectiveness of the composite sensor body 1 monitoring. After judging that the temperature of the monitoring object continues to rise, the composite monitoring processing unit keeps the energization effect of the temperature insulation maintaining unit, and then continuously fixes the magnetic induction ring 5. Due to the heat insulation effect of the temperature insulation sleeve 4, the area of the composite sensor body 1 in contact with the external environment is reduced, thereby reducing the influence of the external temperature on the inside of the composite sensor body 1 while ensuring the effectiveness of the temperature sensing element 13 in collecting temperature data of the monitoring object. In addition, the composite monitoring processing unit controls the air exchange control unit. Since the gas entering the heat exchange cavity of the temperature insulation sleeve 4 can realize heat exchange with the heat exchange liquid 42 located on the lower side through the sealing isolation ring 41, the air exchange control unit controlled by the composite monitoring processing unit controls the micro fan 61. By controlling the micro fan 61 to reciprocate in forward and reverse directions, the micro fan 61 rotates in the forward direction to draw the gas in the transmission vibration space 12 into the heat exchange cavity, and then the gas in the heat exchange cavity is conducted through the sealing isolation ring 41 to heat the heat exchange liquid 42. Subsequently, the micro fan 61 reverses to transport the heated gas from the heat exchange cavity back to the transmission vibration space 12. Such repeated control effectively realizes heat exchange of the gas in the transmission vibration space 12 and the heat exchange cavity, effectively realizes heat exchange protection of the composite sensor body 1, and continuously and effectively maintains the temperature inside the transmission vibration space 12, reduces the influence and damage of heat on the composite circuit board 2 and the vibration element 16, thereby improving the durability of the composite sensor body 1 in a high-temperature environment and effectively ensuring the accuracy and reliability of the monitoring data in a high-temperature environment. And, the composite monitoring processing unit transmits temperature data, vibration data and temperature change data of the monitoring object to the maintenance platform through the cooperation of the monitoring data transmission unit and the signal support rod 15, and at the same time, the composite monitoring processing unit also transmits the early warning alarm signal to the maintenance platform through the cooperation of the early warning unit and the signal support rod 15, verifies and corresponds to the data transmitted by the monitoring data transmission unit, and also transmits the high-temperature abnormal alarm signal to the staff, improves the emergency response efficiency of the staff, and timely maintains and safeguards the monitoring object, and the cooperation of the air exchange control unit and the temperature isolation sleeve 4 effectively realizes the heat exchange protection and temperature isolation protection of the composite sensor body 1, effectively improves the accuracy and reliability of the monitoring data of the composite sensor body 1 in the high-temperature state, improves the effectiveness of the emergency measures generated by the staff, and further improves the effectiveness of the application of the composite sensor body 1 in the high-temperature environment.

[0030] The second embodiment: Figure 4 And Figure 6 The temperature and vibration composite sensor with high temperature resistance is shown, and the present embodiment is an improvement based on the first embodiment. As an optional function, the sealing isolation ring 41 is embedded with a heat conducting rod 44, the upper inner wall of the heat exchange cavity is fixedly connected with a trigger rod 45 cooperating with the heat conducting rod 44, and the upper end between the sealing isolation ring 41 and the upper inner wall of the heat exchange cavity is fixedly connected with a temperature change elastic member 43. The temperature change elastic member 43 is made of spiral memory metal material, which can produce elongation deformation when the upper half of the temperature isolation sleeve 4 produces elastic elongation deformation, and can produce contraction deformation when the temperature rises to the deformation temperature, and can produce recovery deformation after the temperature decreases and recovers. The temperature change elastic member 43 is slidably arranged outside the heat conducting rod 44 and the trigger rod 45. The temperature change elastic member 43 can display and remind the heat absorption state of the heat exchange liquid 42 when the temperature continues to rise and the heat exchange performance of the heat exchange liquid 42 decreases, thereby being able to feedback the heat exchange effect, assist the composite monitoring processing unit to perform parameter control on the air exchange control unit of the composite sensor body 1, and avoid damage to the composite circuit board 2 and the vibration element 16 caused by heat after subsequent continuous heat exchange failure.

[0031] Figure 4 And Figure 6 The input end of the composite monitoring processing unit is also connected with a heat exchange failure feedback unit, the input end of the heat exchange failure feedback unit is signal connected with the trigger rod 45, the cooperation of the heat exchange failure feedback unit and the trigger rod 45 can effectively transmit the heat exchange failure data to the composite monitoring processing unit, so as to facilitate the staff to timely maintain and safeguard the composite sensor body 1, and also effectively generate high-temperature emergency response, improve the efficiency of emergency response, and the data can be mutually verified and corresponding to the monitoring data of the temperature sensing element 13, so as to ensure the accuracy and reliability of the data monitoring and early warning data.

[0032] Figure 4 and Figure 6 The composite monitoring processing unit determines that the temperature of the monitoring object continues to rise, controls the temperature insulation holding unit to fix the adsorption of the magnetic attraction induction ring 5, and controls the heat exchange regulation unit to have a heat exchange protection effect. The heat exchange liquid 42 absorbs heat from the gas with heat in the transmission vibration space 12 by controlling the reciprocating forward and reverse rotation of the micro fan 61. However, when the temperature of the monitoring object continues to rise after the staff receives the early warning signal and monitoring data, and the emergency response or emergency response measures are not effective, the temperature in the transmission vibration space 12 continues to rise under the temperature conduction of the installation head 14, the composite sensor body 1 and the vibration conduction rod. When the heat exchange liquid 42 absorbs heat to the temperature in the transmission vibration space 12, the high temperature will continuously act on the temperature change elastic member 43, causing the temperature change elastic member 43 to produce thermal contraction deformation. Under the restriction of the adsorption of the magnetic attraction induction ring 5, the thermal contraction deformation of the temperature change elastic member 43 will drive the elongation deformation of the lower half of the temperature insulation sleeve 4 under the cooperation of the sealing isolation ring 41, thereby continuously maintaining the temperature insulation protection effect of the temperature insulation sleeve 4. At the same time, the feedback effect of the signal trigger caused by the thermal contraction deformation of the temperature change elastic member 43 can be realized. The contraction of the temperature change elastic member 43 will cause the abutment effect of the heat conduction rod 44 and the trigger rod 45, and the trigger signal is transmitted to the heat exchange failure feedback unit. After receiving the failure feedback data transmitted by the heat exchange failure feedback unit, the composite monitoring processing unit transmits the early warning data to the maintenance platform through the cooperation of the early warning unit and the signal support rod 15, and continues to transmit the early warning signal to the staff, reminding the staff that the high temperature will affect the composite sensor body 1, and the accuracy of the data transmitted by the composite sensor body 1 through the monitoring data transmission unit and the signal support rod 15 needs to be paid attention to. While urging the staff to take timely and effective emergency response measures, the staff can also be reminded to maintain or replace the composite sensor body 1 in time to ensure the effectiveness of the data in the subsequent verification of the emergency measures, avoid the continuous application of the composite sensor body 1 with heat damage, ensure the effectiveness of the subsequent verification data, and the effectiveness of the continuous data monitoring of the monitoring object.

[0033] The above embodiments of the present application are not limited to the actual needs, and various changes made by those skilled in the art within the scope of their knowledge without departing from the concept of the present application still fall within the protection scope of the present application.
