DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides a technical solution: a distributed intelligent optical fiber sensing system for water environment monitoring, including a distribution rod 1, a lower connector 2 is fixed at the lower end of the distribution rod 1, and a cone rod 3 is connected to the lower connector 2, an upper connector 4 is fixed at the upper end of the distribution rod 1, and an extension rod 5 is connected to the upper connector 4.

[0026] Furthermore, the distribution rod 1 is an integrated structure with the lower connector 2 and the upper connector 4. The lower connector 2 and the tapered rod 3, and the upper connector 4 and the extension rod 5 are all threadedly connected. The tapered rod 3 and the extension rod 5 can be freely assembled. At the same time, the tapered rod 3 and the extension rod 5 can also be threadedly connected. In this way, the length of the distribution rod 1 after assembly can be changed at will, and the position of the distribution rod 1 in the overall length can also be changed through assembly. In this way, when inserted into the water, the depth of the distribution rod 1 in the water can be changed to adapt to monitoring work at different depths of water areas.

[0027] Furthermore, the upper ends of the movable seat 6 and the upper connector 4 are both provided with bayonet sockets for fixing the connecting optical fiber 17, and the position of the bayonet sockets protrudes from the outside of the movable seat 6 and the upper connector 4, which is convenient for fixing the connecting optical fiber 17, thereby avoiding the connecting optical fiber 17 from being scattered and affecting the monitoring work.

[0028] A movable seat 6 is movably sleeved on the distribution rod 1 , and a positioning component for positioning the movable seat 6 on the distribution rod 1 is provided on the movable seat 6 , and the positioning component is symmetrically arranged on the side of the movable seat 6 .

[0029] Furthermore, the positioning assembly includes a pressing groove 9, a positioning button 10, a positioning clamp 11 and a first spring 12. The pressing groove 9 is integrally arranged on the movable seat 6. The middle position of the positioning button 10 is connected to the pressing groove 9 through a movable rotating shaft. A positioning clamp 11 is arranged on the inner side of one end of the positioning button 10, and a first spring 12 is arranged on the inner side of the other end. The first spring 12 can ensure that the positioning clamp 11 is always in a state of being pushed inwardly toward the movable seat 6, thereby ensuring the stability of the connection state between the positioning clamp 11 and the distribution rod 1.

[0030] Furthermore, circular grooves are evenly distributed on the outer surface of the distribution rod 1, and the front end of the positioning clamp 11 is embedded in the circular groove on the outer surface of the distribution rod 1, which can increase the stability of the connection between the positioning clamp 11 and the distribution rod 1 and ensure the fixation of the working position of the movable seat 6.

[0031] A connecting seat 13 is fixed on the movable seat 6, and a telescopic rod 7 is connected to the movable axis on the connecting seat 13. Through the extension and retraction of the telescopic rod 7, the working position of the intelligent optical fiber sensing device 8 can be further changed to increase the comprehensiveness of the water area monitoring work. The intelligent optical fiber sensing device 8 is installed on the outer end of the telescopic rod 7, and the intelligent optical fiber sensing device 8 is connected to the connecting optical fiber 17. A limit component for limiting the movement of the telescopic rod 7 is provided on the connecting seat 13.

[0032] Furthermore, the limiting assembly includes a toggle block 14, a limiting top block 15 and a second spring 16. A through groove is provided on the connecting seat 13. The toggle block 14 passes through the through groove and protrudes out of the connecting seat 13. The limiting top block 15 is fixed to the inner end of the toggle block 14. The position movement of the limiting top block 15 can be conveniently controlled by the toggle block 14. A second spring 16 is provided between the limiting top block 15 and the movable seat 6 to ensure that the limiting top block 15 is always in a forward-pushing state.

[0033] Furthermore, the toggle block 14 and the limit top block 15 are integrated into an integrated arrangement, and the limit top block 15 is connected to the through groove on the connecting seat 13 through the toggle block 14 to form a non-rotatable displacement structure, so that the limit top block 15 always moves forward, thereby ensuring that the connection state between the limit top block 15 and the telescopic rod 7 is stable.

[0034] Furthermore, a groove is provided at the tail end of the telescopic rod 7. When the telescopic rod 7 is rotated to a horizontal state, the front end of the limiting top block 15 is embedded in the groove at the tail end of the telescopic rod 7, which can effectively fix the working state of the telescopic rod 7 and ensure the normal monitoring work.

[0035] Specifically, when using the system, the depth of the water area and the working depth of the intelligent optical fiber sensing device 8 must be determined first, so that the corresponding extension rods 5 can be installed on the upper connector 4 and the lower connector 2 at the upper and lower ends of the distribution rod 1. The extension rods 5 can also be disassembled and assembled through threads. According to the depth of the monitored water area, the appropriate length is assembled, and then according to the working depth of the distribution rod 1, different numbers of extension rods 5 can be connected to the lower connector 2 and the upper connector 4 of the distribution rod 1. Finally, the cone rod 3 is installed on the lower connector 2 or the extension rod 5 at the bottom of the lower connector 2, so that the cone rod 3 can be inserted into the bottom of the water to fix the entire distribution rod 1.

[0036] If it is located in the sea, you can choose to connect the upper end of the distribution rod 1 to a floating object and the lower end to a heavy hanging object, so that the distribution rod 1 can be placed in the sea;

[0037] Before the distribution rod 1 is placed in the water area, the telescopic rod 7 with the intelligent optical fiber sensor device 8 can be opened, and the limit top block 15 can be moved by the toggle block 14 to separate the limit top block 15 from the telescopic rod 7, so that the telescopic rod 7 can be rotated freely. After the telescopic rod 7 is rotated to the horizontal, the toggle block 14 is released, and the limit top block 15 is stably embedded and connected with the telescopic rod 7 under the compression of the second spring 16, so that the stability of the horizontal working state of the telescopic rod 7 can be ensured;

[0038] Then, the positioning button 10 is pressed, and the positioning clamp 11 at one end thereof is separated from the distribution rod 1, so that the position of the movable seat 6 on the distribution rod 1 can be adjusted up and down, and can also be rotated left and right, so that the intelligent optical fiber sensing device 8 works in different directions. After the position of the movable seat 6 is determined, the positioning button 10 is released, and under the action of the first spring 12, the positioning clamp 11 is re-embedded and connected in the groove on the distribution rod 1, so that the working position of the movable seat 6 is fixed;

[0039] Finally, the working position of the intelligent optical fiber sensor device 8 can be changed by extending and retracting the telescopic rod 7. According to the above adjustment method, the intelligent optical fiber sensor device 8 on the distribution rod 1 can be placed in different spatial positions for monitoring.

[0040] After the working position of the intelligent optical fiber sensor device 8 is adjusted, the connecting optical fiber 17 is connected to it to ensure the normal operation of the intelligent optical fiber sensor device 8. Finally, the connecting optical fiber 17 is buckled into the bayonet above the movable seat 6 for fixing, which can effectively avoid the scattering of the connecting optical fiber 17 and ensure the stability of the connection state between the connecting optical fiber 17 and the intelligent optical fiber sensor device 8.

[0041] Finally, it is put into the corresponding water area for water environment monitoring. The above is the use process of the system, and the contents not described in detail in this manual, such as the telescopic rod 7, the intelligent optical fiber sensor device 8, and the connecting optical fiber 17 are all existing technologies known to professional and technical personnel in this field.
