Abstract
Description
Technical Field
[0001] The invention relates to the technical field of underground leak detection equipment, in particular to a high-efficiency RFID underground leak detection equipment. Background Art
[0002] Downhole plugging refers to the situation where underground buried equipment or pipelines such as oil fields and oil wells leak or become clogged. RFID downhole plugging equipment is a device that uses radio frequency identification technology to accurately identify and locate plugging points in an underground environment. When a pipeline is clogged or leaks, it may cause changes in the flow of the fluid in the pipeline or other physical changes. These changes may affect the transmission of radio frequency signals near equipment with radio frequency tags. RFID equipment will determine whether there is a problem based on changes in the received signal. For example, if under normal circumstances, the signal strength at a certain location is stable, but suddenly the signal strength drops or disappears completely, it may indicate that a blockage or leak has occurred at that location.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.
[0019] Reference Figures 1 to 4 In an embodiment of the present invention, a high-efficiency RFID downhole plugging device includes: a pipeline 1, an RFID tag 2 is abutted against the outside of the pipeline 1, an RFID tag fixing shell 3 is clamped on the outside of the RFID tag 2, a protective shell 4 is plugged into the outside of the RFID tag fixing shell 3, a fixing ring 5 is plugged into the end face of the protective shell 4, and the fixing ring 5 is sleeved with the pipeline 1.
[0020] Reference Figure 5The RFID tag fixing shell 3 includes a C-shaped fixing plate 31, a limiting plate 32, an extrusion spring 33, a C-shaped connecting plate 34 and a connecting protrusion 35. The limiting plate 32 is provided with two groups, which are symmetrically distributed at the bottom end of the C-shaped fixing plate 31 and fixedly connected to the C-shaped fixing plate 31. The C-shaped fixing plate 31 is plugged with the RFID tag 2, and the bottom end of the RFID tag 2 abuts against the limiting plate 32.

The connecting protrusion 35 is provided with multiple groups, which are evenly distributed at the top of the C-shaped connecting plate 34 and fixedly connected to the C-shaped connecting plate 34. The RFID tag fixing shell 3 is provided with two groups, which are symmetrically distributed at the side end of the pipeline 1, and a group of RFID tags 2 are clamped at the inner end of each group of RFID tag fixing shells 3.
[0021] By adopting the above solution, the limiting plate 32, the extrusion spring 33 and the connection protrusion 35 are arranged to ensure that the connection between the RFID tag 2 and the pipeline 1 is stable and reliable, thereby avoiding accidental falling off or displacement.
[0022] Reference Figure 7 The protective shell 4 includes a C-type protective shell 1 41, a connecting protrusion 2 42, a C-type protective shell 2 43, a connecting jack 44, a connecting slot 1 45 and a connecting slot 2 46.

The connecting slot 1 45 is provided with multiple groups, which are evenly opened on the inner end of the C-type protective shell 1 41. The connecting slot 1 45 is plugged with the connecting protrusion 1 35. There are two groups of connecting slot 2 46, which are symmetrically opened on the top of the C-type protective shell 1 41.

The connecting protrusion 2 42 is I-shaped, and the connecting slot 2 46, the connecting slot 1 45 and the connecting protrusion 1 35 are convex.
[0023] The above scheme is adopted: through the combined design of C-type protective shell 1 41, C-type protective shell 2 43 and connecting protrusion 2 42, comprehensive protection is provided for the RFID radio frequency tag 2, effectively preventing damage or interference to the tag by external factors, and the multiple groups of connection jacks 44 and connection slots, as well as the symmetrical layout design, make it easier for maintenance personnel to inspect or replace the RFID radio frequency tag, saving maintenance time and cost.
[0024] Reference Figure 6The fixing ring 5 includes a connecting ring 51, a connecting pin 52, a threaded barrel 53, a cross groove 54 and a locking ring 55. The connecting pins 52 are provided with multiple groups, which are evenly distributed at the side end of the connecting ring 51 and fixedly connected to the connecting ring 51. The connecting pins 52 are plugged into the connecting socket 44. The threaded barrel 53 is provided at the other end of the connecting ring 51 and fixedly connected to the connecting ring 51. The cross groove 54 is opened on the end face of the threaded barrel 53. The locking ring 55 is threadedly connected to the threaded barrel 53. The fixing ring 5 is provided with two groups, which are symmetrically distributed at both ends of the protective shell 4. The pipeline 1 passes through the fixing ring 5.
[0025] The above scheme is adopted: by setting the connecting pin 52 and the threaded barrel 53, the installation process of the fixing ring 5 is made simpler and faster, and the installation efficiency and convenience are improved. The design of the threaded barrel 53 and the locking ring 55 increases the adjustability of the fixing ring 5, and the fixing degree of the pipeline 1 can be adjusted as needed, making the fixation more flexible and reliable.
[0026] The working principle of the present invention is: when the RFID radio frequency tag 2 needs to be repaired and replaced, the locking ring 55 is first rotated to release the connection between the locking ring 55 and the threaded cylinder 53, and the connecting pin 52 is pulled out from the connecting jack 44, and then the C-type protective shell 2 43 is pushed to make the connecting protrusion 2 42 be pulled out from the connecting slot 2 46, and the C-type protective shell 2 43 is removed, and then the RFID radio frequency tag 2 in the radio frequency tag fixing shell 3 in the C-type protective shell 2 43 and the C-type protective shell 1 41 is pushed to repair and replace the RFID radio frequency tag 2, and then the radio frequency tag fixing shell 3 with the replaced RFID radio frequency tag 2 is connected to the C-type protective shell Plug and fit the RFID tag 2 to the outer wall of the pipe 1, insert the connecting protrusion 2 42 into the connecting slot 2 46, connect the C-type protective shell 1 41 and the C-type protective shell 2 43, and finally insert the connecting pin 52 into the connecting jack 44, so that the connecting ring 51 fits the end face of the C-type protective shell, and rotate the locking ring 55 to lock the threaded cylinder 53 to limit the position of the RFID tag 2; by setting two groups of RFID tags 2, and by squeezing the spring 33, the limit plate 32 and the C-type fixing plate 31, the two groups of RFID tags 2 are fit to the pipe 1, and the gaps and intervals are eliminated, so that the RFID signal and the reader are not interlocked. The transmission between the two groups is more stable and reliable. The two groups of RFID radio frequency tags 2 can provide dual backup. Even if one group of tags fails or is damaged, the other group of tags can still be read, thereby improving the recognition rate and stability of RFID. The I-shaped or convex structure of the connecting protrusion and the connecting slot makes the connection between the radio frequency tag fixing shell 3 and the protective shell 4 more firm and stable, ensuring that the RFID radio frequency tag 2 will not fall off or loosen during the use of the equipment, thereby improving the reliability and durability of the equipment. At the same time, the design of the I-shaped or convex structure also makes it more convenient for maintenance personnel to overhaul or replace the equipment, and the operation is more convenient. It is simple and convenient, and reduces maintenance time and cost. The position of the RFID tag 2 can be restricted by the fixing rings 5 arranged on both sides of the protective shell 4, and the fixing rings 5 fit with both sides of the RFID tag 2, the tag fixing shell 3 and the protective shell 4 to prevent the RFID tag 2 from being accidentally displaced or misplaced during the use of the device, thereby ensuring the stable transmission and accurate identification of the RFID signal. The tight fit between the fixing ring 5 and the RFID tag 2, the tag fixing shell 3 and the protective shell 4 can also effectively prevent the external environmental factors from interfering with or damaging the RFID tag 2, thereby improving the stability and durability of the device.
