Description

Technical Field

[0001] The present invention relates to the field of hydraulic structure health monitoring, and in particular to a hydraulic structure optical fiber multi-mode distributed layout device. Background Art

[0002] Fiber optic sensing technology is a new type of sensing technology developed in recent decades. It uses light waves as sensing signals and optical fibers as transmission carriers to sense and detect external signals. It has advantages over traditional electrical sensors in terms of sensing methods, sensing principles, and signal detection and processing. Compared with traditional sensing elements, fiber optic sensing technology has the advantages of anti-electromagnetic interference, anti-chemical corrosion, good radiation resistance, and is non-electrical, small in size, light in weight, and easy to bend. Therefore, fiber optic sensing technology is often used in health monitoring of hydraulic structures.

[0003] When the sensing optical fiber is affected by external environmental factors such as stress and temperature, the light waves transmitted in the optical fiber are easily modulated by these external fields or quantities, which will lead to changes in the parameters representing the light waves, such as light intensity, phase, frequency, polarization state, etc. By monitoring the changes in this information, information about the external measured parameters can be obtained, but this also brings great trouble to the monitoring of the sensing optical fiber.

[0004] Because if the changes in the optical fiber light wave characterization parameters cannot determine what external factors are interfering and affecting, it is impossible to conduct a single analysis of each environmental factor, nor can it identify the proportion of each influencing factor, nor can it be well targeted for evaluation. Therefore, it is necessary to consider establishing a good auxiliary optical fiber deployment device to facilitate disassembly and evaluation of various factors, and adapt to multiple scenarios. The same is true for hydraulic structures. Currently, there is no device on the market that can deploy sensor optical fibers on hydraulic structures. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0039] like Figure 1 As shown, embodiment 1 of the present invention discloses a multi-mode distributed laying device of optical fiber in a hydraulic structure of the present invention, comprising three main components: a main platform 1, a front crawling platform 2, and a bottom support frame 3;

[0040] like Figure 2-Figure 5 As shown, the main platform includes a curved body 11, a side wall 12, a front barrier wall 14 and a bottom platform 15;

[0041] The arcuate body 11 is connected to the side wall 12, the side wall 12 is connected to the front baffle wall 14, and a first external connecting bolt 13 is arranged at the middle position of the front baffle wall 14;

[0042] The main platform 1 is connected to the bottom bolt 23 on the front platform 2 through the first external connecting bolt 13;

[0043] The bottom connecting bolt 16 is arranged at the bottom of the bottom platform 15 , and the main platform 1 is connected to the top bolt 34 on the bottom support frame 3 through the bottom connecting bolt 16 .

[0044] In a preferred but non-limiting embodiment of the present invention, a second external connecting bolt is provided on the front baffle wall 14 of the main carrier and on the other surface parallel to the front baffle wall. The front crawling platform can be selectively installed on the first external connecting bolt or the second external connecting bolt. The external connecting bolts are provided on both sides so that they can be used interchangeably. When one is used to fix the front crawling platform, the other can be used as a backup or connected to another front crawling platform to extend the use range of the front crawling platform.

[0045] like Figure 6-Figure 8 As shown, the front platform 2 includes a fan-shaped tray 21, a rotating disk 22 and a rotating ball 24;

[0046] In a preferred but non-limiting embodiment of the present invention, the outermost edge of the front platform is a fan-shaped tray 21 with a fan-shaped structure design; the fan-shaped structure design can well provide a pulling force for laying optical fibers;

[0047] Side arms 26 are arranged on both sides of the sector tray 21, and a front arm edge 25 is arranged at one end of the sector tray 21 away from the rotating ball, and the front arm edge 25 is arc-shaped. The arc-shaped design of the front arm edge 25 and the spare part of the side arms 26 can well accommodate the shoulder structure of the operator, making it naturally smooth. A rotating ball 24 is arranged at the bottom of the sector tray 21, and the bottom of the rotating ball 24 is arranged at the center of the rotating disk 22, and a bottom bolt 23 is connected to the center of the bottom of the rotating disk 22.

[0048] Further preferably, the fan-shaped tray 21 can be automatically adjusted 360° around the rotating ball 24. This automatic adjustment design is to achieve the best angle fit under multi-mode layout angles;

[0049] Through the design of the bottom bolts 23 and the rotating disk 22, an indirect connection between the front crawling platform and the main carrier is achieved. This design is mainly for the convenience of replacing the fan-shaped tray. The fan-shaped trays of different sizes can be changed by themselves according to different needs.

[0050] It is worth noting that the side walls 12 of the main platform and the arc-shaped body 11 are of arc-shaped design, which forms a certain height difference with the front crawling platform 2, and the groove design, that is, the concave part of the arc-shaped body, can fit well with the left and right arms of the operator.

[0051] like Figure 9-11 As shown, the bottom support frame includes a bottom column 31, a middle column 32, and a thin column 33, that is, a three-stage linkage structure;

[0052] The bottom column 31 is sleeved with the middle column 32 , and the middle column 32 is sleeved with the thin column 33 . The middle column 32 and the thin column 33 can move up and down to adjust the height of the bottom support frame 3 . A top bolt 34 is arranged on the thin column 33 .

[0053] The bottom column 31 is provided with an electric control button 37 and a motor. The electric control button 37 is used to control the motor to adjust the middle column 32 and the thin column 33 to move up and down, thereby adjusting the height of the bottom support frame 3 .

[0054] The bottom support frame 3 also includes a foot plate 35 and a foot support 36, and a firm connection with the ground is achieved through the foot support 36 and the foot plate 35 on the bottom support frame 3. The bottom support frame 3 contains a three-level linkage structure, namely, three-level height adjustment columns including a bottom column 31, a middle column 32 and a thin column 33, and multi-level linkage adjustment can be achieved through an electric control button 37.

[0055] In a preferred but non-restrictive embodiment of the present invention, a top bolt 34 is arranged on the top of the thin column 33, and the top bolt 34 can be used to well connect the foot support 36 and the arc-surface body 11, and the top bolt on the thin column is designed to be a bolt structure, which can well realize free disassembly and assembly, and the three-level structure of the bottom support frame 3 can also realize free extension and retraction. These two designs greatly reduce the occupied space of the device and effectively ensure its use in a small space.

[0056] Further preferably, the electric control button 37 and the motor can be powered by both ordinary batteries and ion batteries. The electric control button 37 on the bottom column can control the motor to achieve three-level control of the bottom column, middle column and thin column, which can effectively realize the height change of the bottom support frame, and can adjust the changes of the bottom column, middle column and thin column through the electric control button according to the specific angle of the fan-shaped tray.

[0057] Further preferably, there are three sets of foot plates 35 and foot supports 36, and the three sets of structures are on the same circular surface with an angular interval of 120°. The outer side of the foot support 36 is arranged in the form of a foot plate 35 in order to increase different fixing methods and increase the pressing area to enhance the overall stability.

[0058] In a preferred but non-restrictive embodiment of the present invention, when not in use, the foot support 36 and the foot tray 35 can be stored on the outer wall of the base column. When the device needs to be used, the three sets of foot supports 36 and the foot tray 35 at the lower edge of the base column can be selectively opened. The foot tray 35 can be controlled by foot pressure, loading, bolts, etc., and the stability of the device can be controlled by the foot support 36 connected to the foot tray 35. Due to its small size and the cylindrical structure of the bottom support frame, it greatly saves space and can be placed in various occasions, greatly expanding the scope of use of the device.

[0060] Step 1: configure all component structures, and according to the angle of the fan-shaped tray, the fan-shaped tray automatically adjusts 360° around the rotating ball to meet the best angle fit under the multi-mode layout angle;

[0061] Step 2, change to a larger fan-shaped tray, control the electric control button on the bottom column to control the bottom column, middle column, and thin column, and adjust the height of the bottom support frame.

[0062] Step 3, choose to open the three sets of foot supports and foot plates at the lower edge of the bottom column, control the foot plates by foot pressure, loading, bolts, etc., and control the stability of the device through the foot supports connected to the foot plates.
