Abstract
Description
Technical Field
[0001] The utility model relates to a voiceprint sensor, in particular to a voiceprint sensor for pipeline third-party construction monitoring. Background Art
[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be transported by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations.
[0003] When a pipeline has defects or fails, its soundprint will change accordingly. Experienced technicians can judge the operating status based on the sounds made by the pipeline under different operating conditions. At the same time, they can troubleshoot the cause of the failure and accurately identify the soundprint information, which will help operation and maintenance personnel diagnose pipeline defects and identify the cause of the failure. However, when the traditional method uses human ears to measure the sound of pipeline operation, personnel must be close to the part being measured, and due to environmental limitations, the clarity is not ideal.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
[0005] In view of the problems in the related technology, the utility model proposes a voiceprint sensor for pipeline third-party construction monitoring to overcome the above-mentioned technical problems existing in the existing related technology.
[0006] To this end, the specific technical solutions adopted by the utility model are as follows:
[0007] A soundprint sensor for pipeline third-party construction monitoring, comprising an upper clamping plate and a lower clamping plate, one end of the lower clamping plate is connected to the upper clamping plate by a hinge, a cavity is opened inside the upper clamping plate, a monitoring mechanism is arranged inside the cavity, the monitoring mechanism comprises a vibration groove opened on the top end of the upper clamping plate, the vibration groove is interconnected with the cavity, a vibration plate is fixedly connected to the vibration groove, a strain plate is arranged on the vibration plate, the strain plate is fixed in the cavity by a support, a preamplifier is fixedly connected to the center of the top end of the cavity, the preamplifier is electrically connected to the strain gauge, an interface is arranged on one side of the outer surface of the upper clamping plate, one end of the interface is electrically connected to the preamplifier, and a fixing mechanism is arranged on the other end of the lower clamping plate.
[0008] Furthermore, in order to fix the upper and lower clamps on the pipe, the fixing mechanism includes a fixing piece welded on the outer surface of the lower clamp, and the fixing piece is symmetrically provided with grooves. The inside of the groove is hinged to the threaded rod through a connecting piece, and the threaded rod is threaded with a limiting block.
[0009] Furthermore, in order to facilitate disassembly by personnel, a protruding piece is welded on one end of the outer surface of the upper clamping plate, and limiting grooves are symmetrically provided on the protruding piece.
[0010] Furthermore, in order to facilitate personnel to analyze the data, a plug is inserted on the other end of the interface, and one end of the plug is connected to the controller through a wire.
[0011] Furthermore, in order to improve the sealing performance between the vibration groove and the vibration plate, a sealing ring is provided between the vibration groove and the vibration plate, and the sealing ring is fixedly connected to the vibration groove.
[0012] Furthermore, in order to ensure the accuracy of external noise monitoring, sound insulation cotton is fixedly connected to the inner surface of the cavity.
[0013] The beneficial effects of the utility model are:
[0014] 1. Fix the upper and lower clamps on the pipeline to be tested through a fixing mechanism. When the pipeline is running, the vibration generated by the pipeline is transmitted to the vibration plate, and then transmitted to the strain gauge by the vibration plate. Under the action of mechanical stress, the strain gauge causes the relative displacement of the positive and negative charge centers inside the piezoelectric material and polarization occurs, resulting in the appearance of bound charges of opposite signs on the surfaces of both ends of the material, that is, the piezoelectric effect is generated. The piezoelectric effect converts the collected subtle vibrations into current signals and transmits them to the preamplifier for further processing. The processed data is transmitted to the controller, which is convenient for maintenance personnel to diagnose the pipeline.
[0015] 2. By sleeve-mounting the upper and lower clamping plates on the pipe, placing the threaded rod in the limit groove, rotating the limit block to move the limit block on the threaded rod, and as the limit block moves, the limit block fits with the protruding piece, so that the upper and lower clamping plates are fixed on the pipe, further improving the stability of the voiceprint sensor on the pipe, and at the same time, facilitating the disassembly of the voiceprint sensor.
