Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber seismic geophones, in particular to an optical fiber seismic geophone for distributed pipeline detection. Background Art

[0002] Fiber optic seismic detector for distributed pipeline detection is a device that uses fiber optic sensing technology to achieve earthquake monitoring. It is usually used to monitor underground seismic activities around pipelines and prevent pipeline damage or leakage caused by earthquakes.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4In the utility model: a distributed fiber optic seismic geophone for pipeline detection, comprising an installation box 1, the installation box 1 is cylindrical in shape, a drill bit 2 is fixedly connected to the bottom of the installation box 1, the drill bit 2 is conical in shape, a body 3 is fixedly connected to the inner top wall of the installation box 1, a connecting rod 4 is fixedly connected to the top of the installation box 1, a mounting tube 5 is fixedly connected to the top of the connecting rod 4, the top of the mounting tube 5 is open, a filter plate 6, a moisture absorption layer 7 and a fan 8 are fixedly connected to the inner wall of the mounting tube 5, the bottom of the mounting tube 5 is connected to an air inlet pipe 9, the bottom end of the air inlet pipe 9 is connected to the installation box 1, an air outlet pipe 10 is fixedly connected between the installation box 1 and the installation tube 5, the right side of the air outlet pipe 10 is connected to two exhaust pipes 11, and both exhaust pipes 11 are equipped with a one-way valve 12.

[0025] In the utility model, the main body 3 is a distributed fiber optic seismic detector for pipeline detection. The installation box 1 can be used to install the main body 3 and can play an effective protective effect. When fixing the main body 3, the main body 3 is first moved to one side of the pipeline, and then the installation box 1 is inserted into the ground. During the process, the setting of the drill bit 2 can facilitate the user to insert the installation box 1 into the ground until the top of the installation tube 5 is flush with the ground. At this time, the installation of the main body 3 can be completed. The installation process is very convenient and quick. The main body 3 is located on one side of the pipeline at this time. When the main body 3 is working, the user can turn on the fan 8 to inhale the air on the ground into the installation tube 5. The air will be filtered by the filter plate 6. The air that filters the dust will then be absorbed by the moisture absorption layer 7. Then the air will enter the installation box 1 from the air inlet pipe 9. The air will flow inside the installation box 1 and then be discharged into the air outlet pipe 10 and discharged from the exhaust pipe 11. As the air continues to flow in the installation box 1, it will take away the heat generated by the operation of the main body 3, thereby achieving the effect of heat dissipation for the main body 3 located underground, and effectively avoiding the overheating of the main body 3.

[0026] See also Figure 1 , 2 4, wherein: two groups of annularly distributed installation grooves 13 are opened on the outer side of the installation box 1, and the inner walls of the two groups of installation grooves 13 are hinged with clamping plates 14.

[0027] In the present invention, when the top of the installation tube 5 is flush with the ground, the user can pull the installation tube 5 upward to make the top of the installation tube 5 slightly higher than the ground, so as to prevent the water flow on the ground from entering the interior of the installation tube 5. In addition, the installation tube 5 will drive the installation box 1 to rise during the rising process. During the rising process of the installation box 1, the clamping plate 14 will be inserted into the soil, thereby achieving the effect of locking the position of the installation box 1, effectively improving the stability of the fixing of the installation box 1, and improving the firmness of the installation of the main body 3.

[0028] See also Figures 1 to 3, wherein: two support rods 15 are fixedly connected to the top of the installation tube 5, and a rain shield 16 is fixedly connected between the two support rods 15.

[0029] In the present invention, the arrangement of the support rod 15 and the rain shield 16 can protect the installation tube 5 from rain, and can facilitate the user to operate the position of the installation tube 5, thereby improving the practicability of the device.

[0030] See also Figures 1 to 3 , wherein: a top plate 17 is sleeved on the installation cylinder 5, and a ring-shaped limiting rod 18 is fixedly connected to the bottom of the top plate 17.

[0031] In the utility model, the provision of the top plate 17 and the limiting rod 18 can improve the stability of the fixing of the mounting tube 5 and further improve the firmness of the installation of the body 3.

[0032] See also Figure 2 , wherein: a buffer block 19 is fixedly connected to the inner wall of the installation box 1 , and the outer side of the buffer block 19 is in contact with the body 3 .

[0033] In the present invention, the arrangement of the buffer block 19 can provide a certain degree of protection for the main body 3 when an earthquake occurs, thereby improving the practicability of the device.

[0034] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
