On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0021] The oil storage tank floating roof state monitoring device according to the embodiments of the present invention will be described below with reference to the drawings.

[0023] It should be noted that the main explosion-proof box 10 is fixedly connected to the first mounting bracket 14, and the first mounting bracket 14 can be installed on the upper surface of the floating roof 30 by bolts.

[0024] A first power supply module 11, a first inclination sensing module 12, a first wireless transmission module 13 and a temperature sensing module 15 are installed inside the main explosion-proof box 10.

[0025] Among them, the output end of the first power supply module 11 is electrically connected to the first inclination sensing module 12, the first wireless transmission module 13 and the temperature sensing module 15 in a parallel or series manner.

[0026] It should be noted that the first power supply module 11 is used to supply power to the first inclination sensing module 12, the first wireless transmission module 13 and the temperature sensing module 15. The first power supply module 11 can be a dry battery, and the dry battery is a prior art and will not be described in detail here.

[0027] The first inclination sensing module 12 is signal-connected to the first wireless transmission module 13.

[0028] It should be noted that the first inclination sensing module 12 is used to measure the inclination angle of the floating disc 30 and transmit the inclination angle parameter to the control terminal (not shown in the figure) through the first wireless transmission module 13; the first inclination sensing module 12 can be a three-axis gyroscope sensor, and the three-axis gyroscope sensor is a prior art, so it will not be elaborated here.

[0029] The temperature sensing probe of the temperature sensing module 15 passes through the main explosion-proof box 10 and extends to the outside, and the temperature sensing module 15 is signal-connected to the first wireless transmission module 13.

[0030] It should be noted that the temperature sensing module 15 is used to measure the internal temperature of the oil storage tank (not shown in the figure) and transmit the temperature parameter to the control terminal through the first wireless transmission module 13; the temperature sensing module 15 can be a corrosion-resistant thermal resistance temperature sensor, and the corrosion-resistant thermal resistance temperature sensor is a prior art, so it will not be elaborated here.

[0031] It should be noted that the first wireless transmission module 13 can be a data transfer unit, and the data transfer unit is a prior art, so it will not be elaborated here.

[0032] Specifically, during the actual operation, the relevant personnel fix the first mounting bracket 14 on the upper surface of the floating disc 30 through bolts to ensure stable installation, and fix the main explosion-proof box 10 on the first mounting bracket 14 to ensure the relative position stability of the main explosion-proof box 10 and the floating disc 30; install the first power supply module 11, the first inclination sensing module 12, the first wireless transmission module 13 and the temperature sensing module 15 inside the main explosion-proof box 10, and connect the circuits between the modules.

[0033] By setting each sensing module and the first wireless transmission module 13, the inclination angle of the floating disc 30 and the internal temperature of the oil storage tank can be monitored in real time, providing timely and accurate data support for the safe operation of the oil storage tank; potential problems such as the inclination of the floating disc 30 or abnormal temperature in the tank can be discovered in time, which helps to prevent the occurrence of safety accidents such as tank leakage and fire. The application of wireless transmission technology reduces the wiring cost and maintenance difficulty, and improves the reliability and maintainability of the system.

[0034] In an embodiment of the present invention, as Figure 3 shown, the above-mentioned floating disc state monitoring device for an oil storage tank further includes a plurality of secondary explosion-proof boxes 20, and the secondary explosion-proof boxes 20 are installed on the upper surface of the floating disc 30 through the second mounting brackets 24.

[0035] It should be noted that the secondary explosion-proof boxes 20 are fixedly connected to the second mounting brackets 24, and the second mounting brackets 24 can be installed on the upper surface of the floating disc 30 through bolts.

[0036] Inside the secondary explosion-proof box 20, a second power supply module 21, a second inclination sensing module 22, a second wireless transmission module 23, and a gas sensing module 25 are installed.

[0037] Among them, the output end of the second power supply module 21 is electrically connected to the second inclination sensing module 22, the second wireless transmission module 23, and the gas sensing module 25.

[0038] It should be noted that the second power supply module 21 is used to supply power to the second inclination sensing module 22, the second wireless transmission module 23, and the gas sensing module 25. The second power supply module 21 has the same function and type as the first power supply module 11.

[0039] The second inclination sensing module 22 is signal-connected to the second wireless transmission module 23.

[0040] It should be noted that the second inclination sensing module 22 has the same function and type as the first inclination sensing module 12; the second wireless transmission module 23 has the same function and type as the first wireless transmission module 13.

[0041] The monitoring probe of the gas sensing module 25 passes through the secondary explosion-proof box 20 and extends to the outside. The gas sensing module 25 is signal-connected to the second wireless transmission module 23.

[0042] It should be noted that the gas sensing module 25 is used to measure the oil and gas concentration inside the oil storage tank (not shown in the figure), and transmit the oil and gas concentration parameters to the control terminal through the second wireless transmission module 23; the gas sensing module 25 can be an explosion-proof electrochemical gas sensor. The explosion-proof electrochemical gas sensor is a prior art and will not be elaborated here.

[0043] It should be noted that the number of multiple secondary explosion-proof boxes 20 can be 4, 5, 6, 7, 8 secondary explosion-proof boxes 20, etc. The specific number is selected according to actual needs and will not be elaborated here.

[0044] In an embodiment of the present utility model, as Figure 4 shown, multiple secondary explosion-proof boxes 20 are evenly distributed in a ring along the upper surface edge of the floating disc 30.

[0045] It can be understood that near the edge of the floating disc 30 of the secondary explosion-proof box 20, when the floating disc 30 is deformed and oil and gas leaks, the gas sensing module 25 in the secondary explosion-proof box 20 can detect relevant gas parameters in a relatively timely manner and transmit the relevant parameters to the control terminal through the second wireless transmission module 23.

[0046] Furthermore, in an embodiment of the present utility model, as Figure 2 shown, multiple infrared emitters 16 are also installed inside the main explosion-proof box 10. The number of infrared emitters 16 is the same as that of the secondary explosion-proof boxes 20 and they correspond one by one.

[0047] The emitting end of the infrared emitter 16 passes through the main explosion-proof box 10 and extends to the outside.

[0048] The output end of the first power supply module 11 is electrically connected to the infrared emitter 16, and the first power supply module 11 supplies power to the infrared emitter 16.

[0049] It should be noted that the infrared emitter 16 is an explosion-proof infrared emitter, such as a mine intrinsically safe infrared emitter.

[0050] In an embodiment of the present utility model, as Figure 3 and Figure 4 shown, an infrared receiver 26 that is matched with the infrared emitter 16 is installed inside the secondary explosion-proof box 20, and the receiving end of the infrared receiver 26 passes through the secondary explosion-proof box 20 and extends to the outside.

[0051] The output end of the second power supply module 21 is electrically connected to the infrared receiver 26, and the second power supply module 21 supplies power to the infrared receiver 26.

[0052] The infrared receiver 26 is signal-connected to the second wireless transmission module 23.

[0053] It should be noted that the matching infrared emitter 16 and infrared receiver 26 are arranged opposite to each other, that is, the receiving end of the infrared receiver 26 in each secondary explosion-proof box 20 faces the emitting end of the corresponding infrared emitter 16 in the main explosion-proof box 10.

[0054] It should be noted that the area size of the receiving end of the infrared receiver 26 is selected according to actual needs. The larger the area of the receiving end of the infrared receiver 26, the higher the deformation degree of the floating disc 30 that can be accepted. The smaller the area of the receiving end of the infrared receiver 26, the lower the deformation degree of the floating disc 30 that can be accepted.

[0055] It should be noted that the infrared receiver 26 is an explosion-proof infrared receiver, such as a mine intrinsically safe infrared receiver.

[0056] It can be understood that the infrared emitter 16 emits an infrared signal to the corresponding infrared receiver 26. The infrared receiver 26 receives the infrared signal from the infrared emitter 16 and feeds back the received information to the control terminal, then it can be judged that the floating disc 30 has not undergone deformation exceeding the threshold; if the floating disc 30 is deformed, resulting in the straight-line path between a certain or some infrared emitters 16 and the corresponding infrared receivers 26 being blocked, the corresponding infrared receivers 26 will not be able to receive the infrared signal. After feeding back the un-received information to the control terminal, it can be judged that the floating disc 30 has undergone deformation exceeding the threshold.

[0057] It should be noted that the gas sensing module 25, the infrared transmitter 16, and the infrared receiver 26 in the embodiments of the present application are not in a state of running continuously. It is possible to set these three to perform monitoring periodically, or it is possible to set that after the relevant parameters detected by the first inclination sensing module 12, the second inclination sensing module 22, and the temperature sensing module 15 exceed the set thresholds, the gas sensing module 25, the infrared transmitter 16, and the infrared receiver 26 perform monitoring again. The specific operation method is selected according to actual needs and will not be elaborated here.

[0058] It should be noted that when the gas sensing module 25, the infrared transmitter 16, and the infrared receiver 26 perform monitoring, first, the gas sensing module 25 monitors the gas parameters inside the oil storage tank, and then the infrared transmitter 16 and the infrared receiver 26 detect whether the floating roof 30 has a deformation exceeding the threshold.

[0059] In summary, the floating roof state monitoring device for an oil storage tank in the embodiments of the present utility model can remotely monitor the inclination angle of the floating roof and the temperature inside the oil storage tank, avoid being interfered by environmental factors, and improve the accuracy of the monitoring data.
