Description

Technical Field

[0001] The utility model relates to the technical field of collectors, in particular to a wireless digital intelligent collector for a SF6 gas density meter. Background Art

[0002] SF6 gas is a colorless, odorless, non-flammable, non-toxic inert gas with excellent insulation properties and will not age or deteriorate.

[0003] In the existing technology, the density of SF6 gas is crucial to the normal operation of SF6 insulation equipment, and its density meter data needs to be collected, which is usually collected through wireless digital intelligent collectors. The collector, as an access node device at the network layer, can access the aggregation node device at the perception layer for self-organizing network and file management. After completing the access network, it can receive real-time data and alarm information reported by wireless digital meters, and remotely connect to the monitoring platform through the 4G channel to realize the upload of digital meter data of smart substations.

[0004] However, the shell material of traditional wireless digital intelligent collectors is mostly plastic, and the shell and the collector body are often fixed with bolts. This fixing method requires the use of a wrench to screw the bolt in and out. In this way, it is difficult to ensure that the center of the bolt and the threaded hole are on the same axis, and the bolt is prone to "slippage", causing the bolt to be stuck in the threaded hole and unable to move in and out, affecting the disassembly and assembly of the collector.

[0028] See also Figures 1 to 7 The utility model provides a technical solution: a wireless digital intelligent collector for SF6 gas density meter.

[0029] In the first embodiment, a threaded hole 12 is provided inside the collector body 1, and a connecting block 15 is provided inside the collector body 1. The connecting block 15 is a separate part, which is convenient for replacement. A rotating ring 16 is provided on the arc surface of the inner wall of the connecting block 15. The rotating ring 16 can rotate with the rotation of the bolt 2 and will not hinder the installation of the bolt 2. A limiting block 5 is fixed on the arc surface of the inner wall of the rotating ring 16. The cooperation between the limiting block 5 and the limiting groove 8 makes the center of the bolt 3 and the threaded hole 12 on the same axis, preventing the bolt 2 from being offset during installation and avoiding the thread slipping phenomenon of the bolt 2 during installation;

[0030] A through hole 6 is provided on the surface of the shell 2, a bolt 3 is provided on the inner wall surface of the through hole 6, and a limiting groove 8 is provided on the outer surface of the bolt 3. The cooperation between the limiting block 5 and the limiting groove 8 makes the center of the bolt 3 and the threaded hole 12 on the same axis, preventing the bolt 2 from shifting during installation and avoiding the thread slippage of the bolt 2 during installation.

[0031] On the basis of the first embodiment, in order to realize the anti-slip thread of the connecting bolt 3 between the collector body 1 and the shell 2, a baffle groove 10 is provided on the surface of the collector body 1, a second groove 9 is provided on the inner wall surface of the baffle groove 10, a mounting groove 11 is provided on the inner wall surface of the baffle groove 10, a baffle 4 is fixed on the end surface of the connecting block 15, a fixing block 14 is fixed on the surface of the baffle 4, an annular groove 13 is provided on the arc surface of the inner wall of the connecting block 15, and a first groove 7 is provided on the inner side surface of the shell 2;

[0032] There are multiple groups of first grooves 7, which are circumferentially distributed around the through hole 6. The first grooves 7 correspond to and are completely identical to the second grooves 9. There are multiple groups of fixing blocks 14, which are circumferentially distributed on the surface of the baffle 4. The fixing blocks 14 correspond to the first grooves 7. The fixing blocks 14 are clamped in the first grooves 7, so that the connecting block 15 remains fixed when the shell 2 is connected to the collector body 1, and at the same time, the situation that the rotation of the bolt 2 will drive the connecting block 15 to rotate is avoided;

[0033] There are multiple groups of limit grooves 8, which are circumferentially distributed on the outer surface of the bolt 3. There are multiple groups of limit blocks 5, which are circumferentially distributed on the inner wall surface of the rotating ring 16. The limit blocks 5 correspond to the limit grooves 8. The limit blocks 5 are clamped in the limit grooves 8, and the two are movably connected. The cooperation between the limit blocks 5 and the limit grooves 8 makes the centers of the bolt 3 and the threaded hole 12 on the same axis, preventing the bolt 2 from deviating during installation and avoiding the thread slipping phenomenon of the bolt 2 during installation.

[0034] There are multiple groups of connecting blocks 15, which are symmetrically distributed inside the collector body 1. The inner wall of the connecting block 15 is provided with an annular groove 13. There are multiple groups of rotating rings 16, which are symmetrically distributed inside the collector body 1. The rotating rings 16 correspond to the annular grooves 13. The rotating rings 16 are clamped in the annular grooves 13. The two are movably connected. The rotating rings 16 can rotate with the rotation of the bolts 2, and will not hinder the installation of the bolts 2.

[0035] The connecting block 15 corresponds to the mounting groove 11, and the connecting block 15 is clamped in the mounting groove 11, and the two are movably connected. The baffle 4 corresponds to the baffle groove 10, and the baffle 4 is clamped in the baffle groove 10, and the two are movably connected. The connecting block 15 is a separate part for easy replacement.

[0036] In actual use, first match the fixing block 14 with the second groove 9, then clamp the connecting block 15 into the installation groove 11, and then clamp the shell 2 on the side of the collector body 1. While clamping the shell 2, the first groove 7 is clamped with the fixing block 14, and then the bolt 3 is held by hand to match the limiting groove 8 with the limiting block 5 and clamp it, and finally the bolt 3 is clamped in the threaded hole 12 by turning it with a wrench. Due to the cooperation between the limiting block 5 and the limiting groove 8, the center of the bolt 3 and the threaded hole 12 are on the same axis, which prevents the bolt 2 from shifting during installation and avoids the thread slippage of the bolt 2 during installation. The connecting block 15 is a separate part, which is convenient for replacement. This structure is simple and easy to operate, which is conducive to improving its use effect.
