The alarm indicator lamp adopts a red LED lamp. Through the design, the utility model provides an early warning detector bursts based on thing networking, utilizes line type strain transducer to detect pressure vessel deformation situation, warns through alarm device, and the pressure vessel that is convenient for detection personnel to take place to warp fast observes to transmit alarm information through wireless signal transmitting device, be convenient for realize online remote monitoring through the thing networking; the design can realize real-time online monitoring of the risk of bursting caused by stress deformation of the pressure vessel, early warning is carried out in advance, the working state of the pressure vessel is presented in real time, the pressure vessel is prevented from being damaged by bursting deformation of the pressure vessel, and safety risk is reduced.
The wireless signal transmitting device can adopt signal transmission modules such as a wifi module, a GPRS module, a 4G module and a 3G module. The linear strain sensor is made of fiber materials, low-plasticity conductive wires, high-strength wires, linear piezoelectric materials or conductive metal wires with strain effect.
The linear strain sensor can be made of optical fiber material, and the alarm device alarms by using the change of light reflection caused by strain or stress of the optical fiber wound on the outer wall of the pressure container when the pressure container is deformed. In addition, in order to ensure the stress and strain of the sensor to be reliably generated, the optical fiber should be tightly contacted with the outer wall of the pressure container, and if necessary, the optical fiber should be fixed by using an adhesive or the like so as to prevent the optical fiber from sliding on the pressure container.
The linear strain sensor may be implemented using low-plasticity conductive wires, such as conductive ceramic wires, plastic or metal wires, which have a plasticity less than that of the pressure vessel material, or carbon fiber wires, etc. When the pressure container is deformed, the conductive wire is broken, and the alarm device gives an alarm according to the detected broken circuit information. By low plasticity is meant that the plastic deformation rate of the conductive filaments should be less than the plastic deformation rate of the pressure vessel as the pressure vessel deforms to ensure that it can be snapped apart. In addition, in order to ensure that the conductive wire can be reliably disconnected when the pressure container is deformed, the conductive wire and the pressure container should be in close contact, and at least two ends of the conductive wire should be firmly fixed on the outer wall of the pressure container to prevent the conductive wire from sliding on the pressure container.
The linear strain sensor can adopt high-strength filament, such as metal wire, carbon fiber wire or glass wire, and the like, wherein one end of the filament is firmly fixed with the pressure container, and the other end of the filament is connected with a displacement sensor arranged in the alarm device. When the pressure container is deformed, the filament pulls the displacement sensor connected to the non-fixed end of the pressure container, and the alarm device gives an alarm according to an electric signal sent by the displacement sensor. In addition, in order to ensure that the filament can move smoothly on the outer wall of the pressure vessel, and thus pull the displacement sensor, it is not desirable to wind the filament too tightly on the pressure vessel and avoid excessive bending.
The linear strain sensor can adopt piezoelectric materials such as linear quartz, PVDF plastic, BaTiO3 ceramic and the like, and in this case, the alarm device is a pressure-electric signal conversion box utilizing the piezoelectric principle. When the pressure container is deformed, stress or strain is generated on the sensor, the material generates an electric signal due to the piezoelectric effect, and the alarm device gives an alarm according to the electric signal sent by the alarm device. In addition, in order to ensure the stress and strain of the sensor to be reliably generated, the sensor should be tightly contacted with the outer wall of the pressure container, and if necessary, the sensor should be fixed by using an adhesive or the like so as to prevent the sensor from sliding on the pressure container.
The linear strain sensor may employ a conductive wire having a strain effect, in which case the alarm device is a strain-resistance signal conversion box. When the pressure container is deformed, the conductive metal wire generates stress or strain, the material generates a resistance signal due to the strain effect, and the alarm device gives an alarm according to the electric signal sent by the alarm device. In addition, in order to ensure the reliable generation of stress and strain of the sensor, the conductive wire should be tightly contacted with the outer wall of the pressure vessel, and if necessary, the conductive wire should be fixed by using an adhesive or the like so as to prevent the conductive wire from sliding on the pressure vessel.
The lower part of the alarm device is provided with a fixing frame used for being fixed on the pressure container, the fixing frame comprises two connecting pieces, the cross sections of the connecting pieces are semicircular, and two bolt holes are formed in two end parts of each connecting piece. The inner side surface of the connecting piece is provided with a strip-shaped bulge for increasing friction force. Or, a rubber layer is attached to the inner side surface of the connecting piece. The alarm device is connected with the fixing frame through a buckle. Utilize the mount to fix alarm device to pressure vessel's outer wall, the pressure vessel who takes place the deformation is observed fast to the testing personnel of being convenient for. The strip-shaped bulges on the inner side surface of the connecting piece increase the friction force, are not easy to slide, and are convenient for utilizing the gap arrangement linear strain sensor between the connecting piece and the pressure container.
