Description

Technical Field

[0001] The invention relates to the technical field of electromechanical pipeline engineering, and in particular to a pipeline vibration sensor fixing device and an application monitoring method thereof. Background Art

[0002] A pipe support is a structural component used to support overhead pipes. It is used wherever pipes are laid. As a supporting structure for the pipeline, it is set according to the operating performance and layout requirements of the pipeline. Because there is liquid flowing inside some pipes, and some liquid pipelines are pressure pipes, there is a possibility of shaking due to unstable pressure. When the pipeline shakes slightly due to unstable pressure, the vibration amplitude is small and it is difficult to attract attention.

[0003] If the pipeline continues to vibrate abnormally, the bracket will follow the vibration synchronously. As the abnormal vibration time increases, the bracket may become loose, resulting in a decrease in the bracket fixing strength, which in turn leads to an increase in the vibration amplitude. As the abnormal vibration time increases and the vibration amplitude increases, the fixed bracket may eventually fall off, and the pipeline will collapse due to the lack of force on the fixed support point. Because the pipeline has a small initial vibration amplitude and the vibration amplitude increases with the increase in vibration time, the on-duty management personnel failed to immediately discover the vibration of the pipeline or the imminent fall-off, and could not immediately carry out on-site emergency processing, lacking early warning monitoring of pipeline vibration and bracket loosening. Therefore, it is necessary to provide a pipeline vibration sensing and fixing device and its application monitoring method, which can solve the problem of the lack of early warning monitoring of pipeline vibration and bracket loosening in the prior art.

DETAILED DESCRIPTION

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] Please see attached Figure 1 and attached Figure 2 A pipeline vibration sensor fixing device comprises a fixed strip plate 1, an L-shaped card plate 106 and a fixed frame plate 2; the fixed strip plate 1 is installed and fixed by a fixing bolt 101, the vertical section of the L-shaped card plate 106 is fixedly connected to the bottom surface of the fixed strip plate 1, and a pair of L-shaped card plates 106 are symmetrically arranged so that a pair of L-shaped card plates 106 and the fixed strip plate 1 form a placement space; the fixed plate frame 2 is placed in the placement space, and the horizontal sections of the pair of L-shaped card plates 106 support the bottom surface of the fixed plate frame 2; the pipeline of the electromechanical pipeline is passed through the fixed frame plate 2 of the ring structure, and a vibration sensor component is arranged in the fixed frame plate 2, and the vibration sensor component is in contact with and connected to the surface of the pipeline and is externally connected to an external alarm device.

[0042] Preferably, fixing bolts 101 are respectively provided at both ends of the fixing strip 1, so as to facilitate fixing the entire device to the pipe installation position of the electromechanical pipeline, such as the ceiling. A pair of L-shaped clamping plates 106 can be integrally formed on both sides of the bottom of the fixing strip 1, and the pair of L-shaped clamping plates 106 are symmetrically arranged to facilitate supporting and fixing the fixing plate frame 2, forming a pipe hanging bracket for stable and reliable installation of the pipe.

[0043] After the pipeline is passed through and installed in the fixed plate frame 2, it can be connected to the pipeline through the vibration sensor component arranged in the fixed plate frame 2. When the pipeline vibrates, the vibration force can be directly transmitted to the vibration sensor component, so that an alarm signal can be sent to the external alarm device through the vibration sensor component to trigger the alarm, thereby achieving the monitoring purpose of pipeline vibration and bracket loosening early warning, ensuring that the management personnel can obtain pipeline vibration information at the first time.

[0044] Please see attached Figure 1 To Attachment Figure 3The vibration sensing assembly includes a fixed strip plate 204, a vibration sensing box 205, a contact probe 206, a pipe groove 207 and a signal module 208; the fixed strip plate 204 is arranged in the fixed frame plate 2 through an adjustment mechanism and is located above the pipe of the electromechanical pipeline, the vibration sensing box 205, the pipe groove 207 and the signal module 208 are installed on the bottom surface of the fixed strip plate 204, the vibration sensor is installed in the vibration sensing box 205, and the contact probe 206 of the vibration sensor extends to the bottom of the vibration sensing box 205 and is in contact with and connected to the surface of the pipeline; a plurality of vibration sensing boxes 205 are arranged at intervals on the fixed strip plate 204 and are connected in series through connecting wires laid in the pipe groove 207; the connecting wires in the pipe groove 207 are connected to the signal module 208, and the signal module 208 is externally connected to an external alarm device.

[0045] The fixed strip plate 204 is installed above the pipe in the fixed frame plate 2 through an adjustment mechanism to adapt to pipes of different sizes, ensuring that the contact probe 206 can be connected to the surface of the pipe with a certain pressure, thereby ensuring that the pipe can maintain reliable contact when vibrating and drive the contact probe 206 to vibrate synchronously, so as to ensure the effectiveness and sensitivity of monitoring.

[0046] The vibration sensing box 205 is used to install and protect the vibration sensor. The contact probe 206 of the vibration sensor extends out of the vibration sensing box 205 to contact the pipeline and vibrate synchronously with the pipeline, so that the vibration sensor is triggered by the vibration of the contact probe 206, so that it transmits the electrical signal to the signal module 208 through the connecting line laid in the pipe groove 207, and sends an alarm signal to the external alarm device through the signal module 208, thereby playing an early warning role.

[0047] Preferably, the external alarm device can be an alarm device in the form of an audible and visual alarm according to the use requirements. The signal module 208 can be arranged at the end of the fixed strip plate 204, which can not only avoid the pipeline installation space when the pipeline is arranged, but also prevent the signal module 208 from contacting the pipeline and causing collision damage.

[0048] One or more pipes may be passed through the fixed frame plate 2, and one or more vibration sensors may be provided for each pipe to achieve a more accurate and sensitive monitoring effect. All vibration sensors and signal modules 208 may be connected in series through connecting wires laid in the pipe groove 207 to form an alarm circuit. Preferably, the signal module 208 may use wireless communication equipment to send the alarm signal to an external alarm device in the first place through a wireless network.

[0049] Please see attached Figure 4The vibration sensor includes a spring 209, a sensing switch 210 and a fixed arm 211; one end of the contact probe 206 is elastically arranged in the vibration sensing box 205 through the spring 209, and the other end of the contact probe 206 extends through the bottom of the vibration sensing box 205 and contacts the surface of the pipeline; the sensing switch 210 is arranged on the inner wall of the vibration sensing box 205 and is electrically connected to the connecting line in the pipe groove 207, the fixed arm 211 is located in the vibration sensing box 205, and one end of the fixed arm 211 is fixedly connected to the contact probe 206, and the other end of the fixed arm 211 extends toward the sensing switch 210, so that when the contact probe 206 is elastically arranged through the spring 209, the fixed arm 211 can contact and connect with the sensing switch 210.

[0050] When the vibration of the pipeline drives the contact probe 206 to vibrate synchronously, the fixed arm 211 vibrates synchronously with the contact probe 206. Preferably, the induction switch 210 can be a pressure switch and installed on the inner wall of the vibration sensing box 205 above the other end of the fixed arm 211. When the fixed arm 211 vibrates upward synchronously with the contact probe 206, it can resist the pressure sensing end of the induction switch 210, so that the touch induction switch 210 is turned on under the action of pressure to trigger the generation of an electrical signal, and the electrical signal is sent to the signal module 208 through the connecting wire in the pipe groove 207.

[0051] The distance between the sensing switch 210 and the other end of the fixed arm 211 and the pressure trigger threshold of the pressure sensing end of the sensing switch 210 can be adaptively adjusted according to the accuracy requirements of pipeline vibration monitoring to ensure that the sensing switch 210 can be triggered when the pipeline vibration exceeds the set amplitude, thereby achieving effective monitoring and early warning effects.

[0052] Preferably, when the contact probe 206 contacts the pipeline, the spring 209 is in a slightly compressed state, and a small elastic force is generated by the spring 209 to make the contact probe 206 contact the pipeline with a certain pressure, thereby ensuring the synchronization of the pipeline vibration and the contact probe 206 vibration; at the same time, the spring 209 is made of a material with a small elastic coefficient to ensure that the small amplitude vibration of the pipeline can drive the contact probe 206 to vibrate, thereby avoiding affecting the synchronization and sensitivity of the contact probe 206 with the pipeline vibration.

[0053] Please see attached Figure 1 and attached Figure 2 The adjustment mechanism includes a fixed plate 201, a telescopic spring 202 and a fixed sleeve 203; the fixed plate 201 is fixedly arranged on the top inner wall of the fixed frame plate 2, the upper end of the fixed sleeve 203 is connected to the bottom surface of the fixed plate 201 through the telescopic spring 202, and the lower end of the fixed sleeve 203 is fixedly connected to the top surface of the fixed strip plate 204.

[0054] Preferably, the length and elastic coefficient of the telescopic spring 202 can be selected according to the size adaptability of the pipeline and the fixed frame plate 2, so that the fixed strip plate 204 can be set slightly higher than the pipeline, which is convenient for the arrangement and installation of the vibration sensor assembly.

[0055] When the pipeline vibrates significantly, it will collide with the fixed strip plate 204 and compress the telescopic spring 202. The elastic force of the telescopic spring 202 can form a reaction force on the pipeline, thereby reducing the impact of the pipeline vibration on the installation reliability of the entire device and preventing the device from loosening and falling off.

[0056] Preferably, the length of the fixed strip plate 204 is consistent with the inner length of the fixed frame plate 2, so that the fixed strip plate 204 can slide vertically in the fixed frame plate 2, and the fixed strip plate 204 is prevented from rotating in the fixed frame plate 2, thereby ensuring effective contact between the contact probe 206 and the pipeline. Further, a vertical guide rail can be provided on the inner side wall of the fixed frame plate 2 according to actual use requirements, and a slider can be provided at the end of the fixed strip plate 204, and the slider slides along the vertical guide rail to provide guidance and limit for the fixed strip plate 204.

[0057] Please see attached Figure 1 and attached Figure 2 The vertical section of the L-shaped card plate 106 and the vertical section of the fixed frame plate 2 are both formed with a first thread groove 102, so that the vertical section of the L-shaped card plate 106 is fixedly connected to the vertical section of the fixed frame plate 2 through the first fixing bolt 104 via the first thread groove 102; the horizontal section of the L-shaped card plate 106 and the bottom horizontal section of the fixed frame plate 2 are both formed with a second thread groove 103, so that the horizontal section of the L-shaped card plate 106 is fixedly connected to the bottom horizontal section of the fixed frame plate 2 through the second fixing bolt 105 via the second thread groove 103.

[0058] The L-shaped clamp plate 106 is connected to the fixed frame plate 2 via the vertical second fixing bolt 105 and the horizontal first fixing bolt 104, forming a multi-point connection and two-way limit, thereby ensuring the connection reliability between a pair of L-shaped clamp plates 106 and the fixed frame plate 2, and providing a stable and reliable installation bracket for the pipeline.

[0059] Preferably, a thickened portion is formed on the bottom horizontal section of the fixed frame plate 2, and the second fixing bolt 105 passes through the thickened portion.

[0060] Since pipeline vibrations are mostly up and down vibrations, stress is concentrated at the connection between the bottom horizontal section of the fixed frame plate 2 and the horizontal section of the L-shaped clip 106. By setting the thickened part, the structural stability and deformation resistance of the connection between the bottom horizontal section of the fixed frame plate 2 and the horizontal section of the L-shaped clip 106 can be improved.

[0061] Please see attached Figure 1 To Attachment Figure 4, an application monitoring method of a pipeline vibration sensing fixture comprises the following steps:

[0062] Step 1: Fix the fixing strip 1 with a pair of L-shaped clamping plates 106 at the pipeline installation position of the electromechanical pipeline by means of fixing bolts 101 .

[0063] The installation position of the fixed strip 1 can be determined according to the actual pipeline layout requirements. It can be installed and fixed by two or more fixing bolts 101, or by other fixed connection methods such as welding, which will not be repeated here.

[0064] Step 2: Fix the fixed frame plate 2 in the placement space formed by the fixed strip plate 1 and a pair of L-shaped clamping plates 106 .

[0065] The step 2 comprises the following sub-steps:

[0066] Step 2.1: Open a first thread groove 102 on the vertical section of the L-shaped clamping plate 106 and the vertical section of the fixed frame plate 2, so that the vertical section of the L-shaped clamping plate 106 is fixedly connected to the vertical section of the fixed frame plate 2 through the first thread groove 102 by the first fixing bolt 104.

[0067] Step 2.2: Open a second thread groove 103 on the horizontal section of the L-shaped clip 106 and the bottom horizontal section of the fixed frame plate 2, so that the horizontal section of the L-shaped clip 106 is fixedly connected to the bottom horizontal section of the fixed frame plate 2 through the second fixing bolt 105 via the second thread groove 103.

[0068] Step 3: Pass the pipeline through the fixed frame plate 2 and connect it to the surface of the pipeline through the vibration sensor component.

[0069] The step 3 comprises the following sub-steps:

[0070] Step 3.1: Select a telescopic spring 202 of corresponding length according to the diameter of the pipeline, and connect the telescopic spring 202 between the fixed plate 201 and the fixed sleeve 203, so that the fixed strip plate 204 can be horizontally arranged above the pipeline.

[0071] Step 3.2: According to the number and positions of the pipes passing through the fixed frame plate 2, a plurality of vibration sensing boxes 205 with built-in vibration sensors are arranged at corresponding positions of the fixed strip plate 204.

[0072] The number of vibration sensing boxes 205 and their arrangement positions can be adaptively adjusted according to the layout requirements of the pipelines to ensure that each pipeline is equipped with a corresponding vibration sensing box 205 .

[0073] Step 3.3: A pipe groove 207 is provided on the bottom surface of the fixed strip plate 204 , and a plurality of vibration sensing boxes 205 are connected in series via connecting wires laid in the pipe groove 207 .

[0074] The pipe groove 207 is used to pass and protect the connection wires, so that each vibration sensing box 205 can be connected to the signal module 208 .

[0075] Step 3.4: A signal module 208 is arranged on the bottom surface of the fixed strip plate 204 . The signal module 208 is connected to the connection wires laid in the pipe groove 207 and is externally connected to an external alarm device.

[0076] Each vibration sensing box 205 is connected to the signal module 208 via a connecting line. The vibration sensing box 205 and the signal module 208 can be connected in series to form a circuit, or the vibration sensing boxes 205 can be connected in parallel according to actual circuit design requirements, which will not be repeated here.

[0077] Step 4: Monitor the corresponding pipeline through the vibration sensor assembly, and trigger the vibration sensor when the pipeline vibrates, so that the signal module 208 alarms through the external alarm device.

[0078] The step 4 comprises the following sub-steps:

[0079] Step 4.1: When the pipeline vibrates, the contact probe 206 vibrates synchronously with the pipeline under the action of the vibration force and compresses the spring 209.

[0080] By setting the spring 209 in a slightly compressed state, it is ensured that the contact probe 206 can be in contact and connected with the pipeline surface within the vibration range, thereby ensuring that the induction switch 210 can be triggered by the contact probe 206 in the first time when the pipeline vibrates.

[0081] Step 4.2: The contact probe 206 drives the fixed arm 211 to vibrate synchronously, so that the fixed arm 211 can be in contact with the induction switch 210.

[0082] Preferably, the fixed arm 211 can be made of a lightweight material such as plastic, so that it can vibrate synchronously with the contact probe 206 and contact the sensing switch 210 during the vibration process.

[0083] Step 4.3: The induction switch 210 is triggered by the contact of the fixed arm 211 , and sends an electrical signal to the signal module 208 through the connecting wire in the tube groove 207 .

[0084] Step 4.4: The signal module 208 sends an alarm signal to the external alarm device, causing the external alarm device to sound an alarm.

[0085] Preferably, the external alarm device can send out alarm signals by flashing, beeping, text messages, WeChat and other network information push methods, so as to ensure the first-time warning when pipeline vibration occurs, and the management personnel can know the operating status of the pipeline in time to achieve effective monitoring and early warning effects.
