[0002] A float is an energy-saving and environmentally friendly device that rises and falls with the liquid level in the tank through buoyancy. It is installed within the tank to reduce volatilization of the medium within the tank, minimize losses, conserve energy, and protect the environment. By installing the float, the tank seals the stored medium and reduces its temperature, thus saving energy and protecting the environment.

[0003] Traditional floats often use telescopic bladders installed on the columns to prevent oil and gas from escaping through the openings in the column sidewalls. However, these bladders have been found to detach or even tear over time, causing organic pollutants to leak and potentially causing the float to become stuck and deflect. Overheating of the bladders can also pose a fire risk.

[0004] At present, when inspecting the telescopic bag on the column, the inspection can only be carried out after the gas concentration in the tank reaches a certain condition. In addition, it is dangerous for inspectors to climb onto the tank, which leads to obvious shortcomings of untimely inspections. In addition, manual inspections have the disadvantage of large errors in inspection results. Utility Model Content

[0027] Example 1:

[0028] Reference Figure 1-6 , a tank telescopic bag operation safety monitoring system includes a pillar 1, a bag body 2 is provided on the surface of the pillar 1, and a distributed optical fiber temperature sensor 3 is bonded to the inner wall of the bag body 2. There are two distributed optical fiber temperature sensors 3, and the two distributed optical fiber temperature sensors 3 are respectively located on the left and right sides of the pillar 1. The distributed optical fiber temperature sensor 3 is realized by using the Bragg diffraction phenomenon in the optical fiber Bragg grating. Bragg diffraction is a diffraction effect based on wavelength. Under temperature changes, the wavelength of the Bragg peak will shift. Specifically, the corresponding temperature change can be deduced by measuring the wavelength change of the Bragg peak. The surface of the bag body 2 is fitted with a clamp 4, and the bag body 2 is fixed to the pillar 1 by the clamp 4. The inner wall of the bag body 2 is bonded with a spiral optical fiber filament 5, and the real-time shape of the bag body 2 is restored by the spiral optical fiber filament 5. The front of the bag body 2 and the front of the pillar 1 are fixedly connected with a support 6, and the inner wall of the support 6 A fiber Bragg grating tension sensor 7 is fixedly connected. The fiber Bragg grating tension sensor 7 is a sensor based on the grating principle and is used to measure the tensile or compressive deformation of the optical fiber. When the optical fiber in the fiber Bragg grating tension sensor 7 is subjected to tension, the tension causes the wavelength of the fiber Bragg grating to shift. Then, according to the Bragg formula, the magnitude of the tension can be calculated by detecting the change in the wavelength or diffraction angle of the incident light. The input end of the distributed optical fiber temperature sensor 3, the input end of the spiral optical fiber filament 5 and the input end of the fiber Bragg grating tension sensor 7 are all connected to a transmission optical fiber filament 8. The input end of the transmission optical fiber filament 8 is connected to a demodulator 9. Through the demodulator 9 and the transmission optical fiber filament 8, the initial incident light is emitted into the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the fiber Bragg grating tension sensor 7, and the reflected light reflected by the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the fiber Bragg grating tension sensor 7 is received. The demodulator 9 is connected to a processor 10 via a network cable.

[0029] The processor 10 includes a data acquisition module, a data calculation module, a first comparison module, a data storage module, a feedback module and a wireless transmission module. The output end of the demodulator 9 is electrically connected to the input end of the data acquisition module, the output end of the data acquisition module is electrically connected to the input end of the data calculation module, the output end of the data calculation module is electrically connected to the input end of the first comparison module, the output end of the data storage module is electrically connected to the input end of the data calculation module and the input end of the first comparison module respectively, the output end of the first comparison module is electrically connected to the input end of the feedback module, the output end of the feedback module is electrically connected to the input end of the wireless transmission module, the output end signal of the wireless transmission module is connected to the central control display screen and the mobile device, the wireless transmission module includes a 5G module and a WIFI module, and the mobile device includes a mobile phone and a tablet computer.

[0030] The data calculation module uses the formula nλ = 2Λsin(θ), where n is the order of the grating (usually 1), λ is the wavelength of the incident light, Λ is the grating period, and θ is the angle of incidence. When the fiber is subjected to tension, the grating period changes, thereby changing the value of Λ. By measuring the change in the grating period and combining it with the Bragg formula, the applied tension can be calculated.

[0031] The formula used in the data calculation module is Δλ=λ*α*ΔT, where Δ is the wavelength shift of the Bragg peak, λ is the wavelength of the incident light, α is the thermal expansion coefficient of the optical fiber material, and ΔT is the temperature change. Under temperature changes, the wavelength of the Bragg peak will shift. By measuring the wavelength change of the Bragg peak, the corresponding temperature change can be deduced.

[0032] Example 2:

[0033] Reference Figure 4 The output end of the feedback module is electrically connected to the recording and storage module, and the output end of the recording and storage module is electrically connected to the input end of the wireless transmission module. The data output by the feedback module each time can be stored through the recording and storage module, and the user can view the historical status information of the bag cover body 2 through the central control display screen and mobile device through the wireless transmission module.

[0034] Example 3:

[0035] Reference Figure 4The input end of the data calculation module is electrically connected to the data generation module, the output end of the data generation module and the output end of the data storage module are electrically connected to the retrieval module, the output end of the data calculation module, the output end of the retrieval module and the input end of the feedback module are electrically connected to the second comparison module. The data generation module can periodically send a set of preset data to the data calculation module, and calculate the received data through the data calculation module. Then, the calculation result of the data calculation module is compared through the cooperation of the retrieval module and the second comparison module. If the calculation result is equal to the data stored in the data storage module, it means that the data calculation module is operating normally. If the calculation result is not equal to the data stored in the data storage module, it means that the data calculation module is abnormal, and the comparison result is fed back to the central control display screen and the mobile device through the feedback module, so that the user can promptly discover the abnormality of the data calculation module.

[0036] Example 4:

[0037] Reference Figure 4 The output end of the wireless transmission module and the input end of the data storage module are both electrically connected to the data input module. Through the cooperation of the wireless transmission module, the data input module and the data storage module, the user can wirelessly input data into the data storage module through a mobile device.

[0038] In the present invention, when the storage tank telescopic bag operation safety monitoring system is in operation, the demodulator 9 sends initial incident light to the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the optical fiber Bragg grating tension sensor 7, and receives the reflected light reflected by the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the optical fiber Bragg grating tension sensor 7. Then, the demodulator 9 transmits the received reflected light data to the data acquisition module, and pre-processes the data through the data acquisition module. The pre-processed data is transmitted to the data calculation module. Then, the data calculation module calculates the received data according to the formula stored in the data storage module, and calculates the current shape, temperature and whether the bag body 2 is detached. Then, The calculation result is compared with the threshold value stored in the data storage module through the first comparison module. If the calculation result is less than the threshold value, it indicates that the state of the bag sleeve body 2 is normal. Then, the current state of the bag sleeve body 2 is transmitted to the wireless transmission module through the feedback module, and the user can view the current state of the bag sleeve body 2 on the central control display screen and the mobile device through the wireless transmission module. When the calculation result is greater than the threshold value, the first comparison module generates an alarm message. Then, the current state of the bag sleeve body 2 and the alarm message are transmitted to the wireless transmission module through the feedback module, and the central control display screen and the mobile device send out an alarm through the wireless transmission module, and the current state of the bag sleeve body 2 can be viewed on the central control display screen and the mobile device.

[0039] When the storage tank telescopic bag operation safety monitoring system is in self-inspection, the data generation module can periodically send a set of pre-set data to the data calculation module, and the data calculation module calculates the received data. Then, the retrieval module extracts the corresponding data based on the data generated by the data generation module and transmits it to the second comparison module. Then, the calculated data and the stored data are compared by the second comparison module. If the calculation result is equal to the data stored in the data storage module, it means that the data calculation module is operating normally. If the calculation result is not equal to the data stored in the data storage module, it means that the data calculation module is abnormal, and the comparison result is fed back to the central control display screen and the mobile device through the feedback module. At this time, the user is reminded to repair the storage tank telescopic bag operation safety monitoring system in time.
