Technical Field

[0001] The present invention relates to the technical field of floating plate inclination angle detection equipment, and in particular to a floating plate inclination angle detection device. Background Art

[0002] Due to the soft geology in coastal areas, foundation settlement is prone to occur, which causes the tank body to deform and the floating plate to tilt, which can easily lead to safety accidents such as floating plate jamming and sinking, and even cause accidents such as oil leakage, fire or explosion, which seriously affect social and environmental safety and cause significant economic losses. At present, the detection of the inclination of the floating plate of floating roof storage tanks still mainly relies on manual inspections. On the one hand, there are large human errors in the detection data, which is not accurate enough; on the other hand, the detection wastes a lot of human resources, and the detection data cannot be fed back in real time.

[0003] That is to say, the floating plate inclination angle detection in the prior art has the problems of poor accuracy and poor real-time performance. Summary of the invention

[0004] The main purpose of the present invention is to provide a floating plate inclination angle detection device to solve the problems of poor accuracy and poor real-time performance in the floating plate inclination angle detection in the prior art.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a floating plate inclination detection device, comprising: a box body, wherein there is liquid in the box body; a bottom plate, wherein the box body and the bottom plate are spaced apart and a test space is formed therebetween; a fiber grating sensor, wherein the fiber grating sensor comprises a first fiber grating sensor and a second fiber grating sensor spaced apart in the test space; and a connecting structure, wherein the box body and the bottom plate are detachably connected via the connecting structure, and when the box body and the bottom plate are connected, two sides of the bottom of the box body are respectively in contact with the first fiber grating sensor and the second fiber grating sensor.

[0006] Furthermore, the fiber grating sensor is arranged on the bottom plate; or the fiber grating sensor is arranged on the box body.

[0007] Furthermore, the floating plate inclination angle detection device also includes a fixing structure, and the fiber grating sensor is installed on the bottom plate through the fixing structure.

[0008] Furthermore, the base plate has a groove, and the fixing structure includes a clamp and a bolt. The clamp is used to fix the fiber grating sensor in the groove, and the bolt passes through the clamp and the base plate in sequence to lock and fix the two.

[0009] Furthermore, at least a portion of the fiber grating sensor protrudes from the notch of the groove, so that at least a portion of the fiber grating sensor abuts against the box.

[0010] Furthermore, the box body is rectangular, and the rectangular box body includes: a main body, a top of the main body has an opening; a top plate, the top plate cover is arranged on the main body to cover the opening, and a accommodating space is formed between the main body and the top plate, the liquid is located in the accommodating space, and the liquid does not fill the accommodating space.

[0011] Furthermore, the box body also includes a sealing structure, and the sealing structure is arranged between the top plate and the main body.

[0012] Further, the liquid is one of ethanol, saline and water.

[0013] Furthermore, the connection structure is a connection plate, there are multiple connection plates, and at least two sides of the box body are fixedly connected to the bottom plate through the connection plates.

[0014] Furthermore, the floating plate inclination angle detection device also includes a floating plate, the bottom plate is fixedly connected to the floating plate by a bolt structure, and the floating plate is located on a side of the bottom plate away from the box body.

[0015] By applying the technical solution of the present invention, a floating plate inclination detection device includes a box body, a bottom plate, a fiber grating sensor and a connecting structure, wherein there is liquid in the box body; the box body and the bottom plate are spaced apart and a test space is formed therebetween; the fiber grating sensor includes a first fiber grating sensor and a second fiber grating sensor spaced apart in the test space; the box body and the bottom plate are detachably connected via the connecting structure, and when the box body and the bottom plate are connected, two sides of the bottom of the box body are respectively in contact with the first fiber grating sensor and the second fiber grating sensor.

[0016] The spacing between the box and the bottom plate is conducive to ensuring the stability of the fiber grating sensor in the test space, and at the same time, it can ensure the abutment strength between the box and the fiber grating sensor, avoid the formation of a gap between the box and the fiber grating sensor, thereby affecting the detection accuracy of the fiber grating sensor, and ensure the abutment stability between the box and the fiber grating sensor. The box and the bottom plate are detachably connected through a connecting structure. This arrangement enables the connecting structure to connect the box and the bottom plate, avoiding the risk of shaking or separation between the box and the bottom plate during operation, and ensuring the stability of the structure of the floating plate inclination detection device.

When the box is connected to the bottom plate, the two sides of the bottom of the box are respectively abutted against the first fiber grating sensor and the second fiber grating sensor. This arrangement allows the liquid in the box to flow under the action of gravity when the floating plate is in an inclined state, causing the liquid in the box to flow in the inclined direction, thereby causing the pressure of the first fiber grating sensor and the second fiber grating sensor that are in contact with the bottom of the box on both sides to change, thereby causing the center wavelength of the fiber grating sensor to change. By comparing the changes in the center wavelength, the change in the inclination angle of the floating plate can be obtained, and the inclination direction of the floating plate can also be preliminarily determined. This arrangement allows the working state of the floating plate to be monitored in real time through the floating plate inclination detection device, further reducing the possibility of safety hazards.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0028] In order to solve the problems of poor accuracy and poor real-time performance in floating plate inclination angle detection in the prior art, the present invention provides a floating plate inclination angle detection device.

[0029] like Figures 1 to 4 As shown, the floating plate inclination detection device includes a box body 10, a bottom plate 20, a fiber grating sensor and a connecting structure, wherein there is liquid in the box body 10; the box body 10 and the bottom plate 20 are spaced apart and a test space is formed therebetween; the fiber grating sensor includes a first fiber grating sensor 30 and a second fiber grating sensor 40 spaced apart in the test space; the box body 10 and the bottom plate 20 are detachably connected via the connecting structure, and when the box body 10 and the bottom plate 20 are connected, the two sides of the bottom of the box body 10 are respectively in contact with the first fiber grating sensor 30 and the second fiber grating sensor 40.

[0030] The spacing between the box 10 and the bottom plate 20 is conducive to ensuring the stability of the fiber Bragg grating sensor in the test space, and at the same time, it can ensure the abutment strength between the box 10 and the fiber Bragg grating sensor, avoid the gap between the box 10 and the fiber Bragg grating sensor, thereby affecting the detection accuracy of the fiber Bragg grating sensor, and ensure the abutment stability between the box 10 and the fiber Bragg grating sensor. The box 10 and the bottom plate 20 are detachably connected through the connecting structure. Such a setting enables the connecting structure to play the role of connecting the box 10 and the bottom plate 20, avoiding the risk of shaking or separation of the box 10 and the bottom plate 20 during the working process, and ensuring the stability of the structure of the floating plate inclination detection device. At the same time, it is convenient for the disassembly and maintenance of the floating plate inclination detection device, which is conducive to reducing the difficulty of disassembly and assembly of the floating plate inclination detection device. When the box 10 is connected to the bottom plate 20, the two sides of the bottom of the box 10 are respectively abutted with the first fiber Bragg grating sensor 30 and the second fiber Bragg grating sensor 40. This arrangement enables the liquid in the box 10 to flow under the action of gravity when the floating plate is in an inclined state, so that the liquid in the box 10 flows in the inclined direction, thereby changing the pressure of the first fiber grating sensor 30 and the second fiber grating sensor 40 abutting on both sides of the bottom of the box 10, thereby changing the central wavelength of the fiber grating sensor. By comparing the change in the central wavelength, the change in the inclination angle of the floating plate can be obtained, and the inclination direction of the floating plate can also be preliminarily determined. This arrangement enables the working state of the floating plate to be monitored in real time through the floating plate inclination detection device, further reducing the possibility of safety hazards. At the same time, it saves manual inspections, saves costs, avoids the generation of human errors, and is conducive to ensuring the accuracy and stability of the floating plate inclination detection. It can provide a strong guarantee for the normal production and operation of the storage tank on the floating plate.

[0031] In addition, the fiber grating sensor has the characteristics of anti-interference, small size and high precision. This setting ensures the measurement accuracy of the floating plate inclination detection device and the accuracy of the detection results.

[0032] It should be noted that the above-mentioned fiber grating sensor includes an optical fiber.

[0033] Specifically, the fiber Bragg grating sensor is arranged on the bottom plate 20. This arrangement enables the bottom plate 20 to provide an installation position for the fiber Bragg grating sensor, thereby improving the reliability of the use of the fiber Bragg grating sensor.

[0034] Of course, the fiber Bragg grating sensor can also be set on the box 10. As long as it can be ensured that at least a part of the fiber Bragg grating sensor can abut against the bottom of the box 10, when the floating plate tilts, the liquid inside the box 10 will flow in the tilting direction due to the effect of gravity, so that the weight of the liquid on one side of the box 10 is greater than the weight of the liquid on the other side of the box 10. At this time, the center wavelengths of the first fiber Bragg grating sensor 30 and the second fiber Bragg grating sensor 40 respectively abutting against the two sides of the bottom of the box 10 change. Then, by comparing the changes in the center wavelength, the changes in the tilt direction and inclination angle of the floating plate can be known.

[0035] Specifically, the floating plate inclination angle detection device further includes a fixing structure, and the fiber Bragg grating sensor is mounted on the bottom plate 20 through the fixing structure. This arrangement avoids the risk of the fiber Bragg grating sensor shaking or detaching from the bottom plate 20 during operation, which is conducive to ensuring that the fiber Bragg grating sensor can operate stably. At the same time, it can ensure the stability of the fiber Bragg grating sensor abutting against the box 10, and ensure the accuracy of the floating plate inclination angle detection process.

[0036] like Figure 1 and Figure 3 As shown, the base plate 20 has a groove, and the fixing structure includes a clamp 60 and a bolt 70. The clamp 60 is used to fix the fiber grating sensor in the groove, and the bolt 70 passes through the clamp 60 and the base plate 20 in sequence to lock and fix the two. This arrangement allows at least a portion of the fiber grating sensor to be accommodated in the groove, so that the groove provides an accommodation space for the fiber grating sensor, thereby improving the reliability and stability of the fiber grating sensor. At the same time, through the arrangement of the bolt 70 and the clamp 60, the assembly strength of the fiber grating sensor and the groove is enhanced, and the assembly stability and working stability of the fiber grating sensor are further enhanced. Moreover, this arrangement makes the fiber grating sensor easy to disassemble, reduces the difficulty of installation and disassembly, and facilitates the inspection and replacement of the fiber grating sensor.

[0037] Specifically, at least a portion of the fiber Bragg grating sensor protrudes from the notch of the groove, so that at least a portion of the fiber Bragg grating sensor abuts against the box 10. This arrangement allows the box 10 to abut only against the fiber Bragg grating sensor, but not against the bottom plate 20, so that the box 10 is placed on the fiber Bragg grating sensor, and the bottom of the box 10 is spaced from the bottom plate 20, so that the box 10 can abut against the fiber Bragg grating sensor more fully, so as to ensure that the fiber Bragg grating sensor can stably detect the weight change on both sides of the box 10, so as to achieve the accuracy of the floating plate inclination detection.

[0038] like Figure 1As shown, the box 10 is rectangular, and the rectangular box 10 includes a main body 11 and a top plate 12. The top of the main body 11 has an opening; the top plate 12 is covered on the main body 11 to cover the opening, and a storage space is formed between the main body 11 and the top plate 12. The liquid is located in the storage space, and the liquid does not fill the storage space. This arrangement allows the box 10 to provide a storage space for the liquid, and at the same time, the liquid in the box 10 does not fill the entire storage space, so as to ensure the stable flow of the liquid in the box 10, so as to ensure that when the floating plate tilts, the liquid in the box 10 converges in the tilting direction as the floating plate tilts, thereby changing the weight on both sides of the box 10, thereby changing the pressure of the first fiber grating sensor 30 and the second fiber grating sensor 40 respectively abutting on both sides of the bottom of the box 10, resulting in a change in the central wavelength, and then the tilt direction and the size of the inclination angle of the floating plate can be known through the change in the central wavelength.

[0039] It should be noted that the liquid in the box 10 is half full, which makes the detection of the inclination angle of the floating plate more sensitive, so as to ensure the accuracy and sensitivity of the measurement result.

[0040] It should be noted that there are two grooves on the bottom plate 20, which respectively place the first fiber grating sensor 30 and the second fiber grating sensor 40, and the extension direction of the groove is perpendicular to the extension direction of the box 10. The shape of the groove matches the shape of the fiber grating sensor. The shape of the groove can be appropriately changed according to the fiber grating sensor. It is mainly used to place the fiber grating sensor to ensure that the fiber grating sensor can work stably.

[0041] Specifically, the box body 10 further includes a sealing structure, which is arranged between the top plate 12 and the main body 11. This arrangement enables the sealing structure to play a sealing role, avoiding the risk of the top plate 12 and the main body 11 being separated during operation, and at the same time preventing the liquid in the box body 10 from leaking out of the gap between the top plate 12 and the main body 11, thereby ensuring the sealing of the accommodating space and ensuring the stability of the operation of the box body 10.

[0042] It should be noted that the above-mentioned sealing structure is a sealing gasket.

[0043] Specifically, the liquid is one of ethanol, salt water and water. The type of liquid can be selected according to the specific situation. It can be adjusted appropriately according to the change of the ambient temperature of the installation, and in principle, the fluidity of the liquid can be maintained at the lowest temperature. For example, in extremely cold areas, the liquid can be ethanol; in areas with a temperature of about 0°C, the liquid can be salt water; in areas with a temperature above 0°C all year round, the liquid can be water.

[0044] like Figure 1As shown, the connection structure is a connection plate 50, and there are multiple connection plates 50. At least two sides of the box body 10 are fixedly connected to the bottom plate 20 through the connection plates 50. Specifically, there are 4 connection plates 50. The four circumferential side walls of the box body 10 are fixedly connected to the bottom plate 20 through different connection plates 50, respectively. This arrangement is conducive to ensuring the connection strength and connection stability of the box body 10 and the bottom plate 20, and at the same time ensures the abutment stability of the box body 10 and the fiber grating sensor, and ensures that the floating plate inclination detection device can operate stably.

[0045] Specifically, the floating plate inclination detection device also includes a floating plate, and the four corners of the bottom plate 20 have threaded holes 21. The bottom plate 20 is fixedly connected to the floating plate by a bolt structure, and the floating plate is located on the side of the bottom plate 20 away from the box body 10. The floating plate is used to carry the storage tank. This arrangement enables the floating plate inclination detection device to provide a strong guarantee for the normal production and operation of the storage tank. The possibility of safety accidents caused by the tilt of the floating plate during operation is further reduced. At the same time, this arrangement makes the floating plate inclination detection device and the floating plate easy to install and disassemble. Only by disassembling the bolt structure, the floating plate inclination detection device can be moved to other floating plates for inclination detection, which enhances the scope of application of the floating plate inclination detection device and enhances versatility.

[0046] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0047] 1. The present invention realizes the detection of the inclination angle of the floating plate by adding a fiber grating sensor device, which can realize long-distance real-time monitoring, effectively shorten the working time of the staff, increase the working efficiency of the staff, save costs, and facilitate operation.
