[0024] Please see Figures 1-6This utility model provides the following technical solution: An outdoor signal acquisition device for a new type of power distribution system, comprising a smart meter body 1, a limiting block 2 abutting the surface of the smart meter body 1, a protective cover 3 connected to the surface of the limiting block 2, the intersection of the protective cover 3 and the limiting block 2 being fixedly connected to the front end of the mounting frame 4, a limiting groove 5 being transversely opened on the longitudinal end surface of the protective cover 3, a limiting frame 6 being engaged with the surface of the limiting groove 5, a rectangular groove surface on the back side of the limiting frame 6 abutting the front end of the smart meter body 1, a mounting groove 7 being opened on the top of the limiting frame 6, a micro motor 8 being mounted on one side surface of the mounting groove 7, a lead screw 9 being threadedly connected to the transmission end of the micro motor 8, and a lead screw 9 being threadedly connected to the other side surface of the lead screw 9. A bearing 10 is fitted onto a sleeve, and the other side of the bearing 10 is connected to a mounting plate 11. The bottom of the mounting plate 11 is connected to the surface of the mounting groove 7 at the top of the limit frame 6. A moving block 12 is threaded onto the surface of the lead screw 9, and a connecting rod 13 is threaded onto the top of the moving block 12. A cleaning brush 14 is fitted onto the surface of the connecting rod 13, and a retaining strip 15 is connected to the bottom of the cleaning brush 14. In this design, the smart meter body 1 constitutes the main body of the remote prepaid smart energy meter, and a large number of related components are set in the remote prepaid smart energy meter. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0025] The model of the remote prepaid smart energy meter in this solution is: DDZY666 single-phase remote prepaid smart energy meter.

[0026] Preferably, the mounting slot 7 has an "I" shaped structure, and the length of the horizontal end of the mounting slot 7 is adapted to the front display screen of the smart meter body 1.

[0027] In practical use, the mounting groove 7 on the top of the limiting frame 6 can be used to easily fix the micro motor 8, the lead screw 9 and the mounting plate 11. At the same time, it can also limit the movement range of the moving block 12 connected to the thread on the lead screw 9, so that it can keep moving in parallel at the front end of the smart meter body 1.

[0028] Preferably, the two transverse ends of the limiting frame 6 are provided with columnar protrusions, and the shape and size of the protrusions are adapted to the limiting groove 5.

[0029] In practical use, the protrusions on both sides of the limiting frame 6 slide on the limiting groove 5, thereby fixing the position of the smart meter body 1 on the protective cover 3 by fixing the position of the limiting frame 6 at the front end of the protective cover 3.

[0030] Preferably, the limiting frame 6, the mounting groove 7, the lead screw 9, the bearing 10, the mounting plate 11, and the moving block 12 form a threaded sliding connection structure.

[0031] In actual use, the micro motor 8 is started to rotate, thereby driving the connected lead screw 9 to rotate within the bearing 10 provided on the mounting plate 11 on the other side. At the same time, when the lead screw 9 rotates, the threaded moving block 12 on it is driven to move parallel to the top of the limit frame 6.

[0032] Preferably, the connecting rod 13 has an "L" shaped structure, and the bottom of the longitudinal end of the connecting rod 13 is provided with a threaded structure, which is adapted to the threaded groove on the top of the moving block 12.

[0033] In practical use, the threaded structure at the bottom of the connecting rod 13 facilitates fixing and disassembling its position on the top of the moving block 12. When it is installed on the top of the moving block 12, it can be driven by the moving block 12 to move in parallel. When the connecting rod 13 moves, its lateral end moves together in the rectangular groove opened at the front end of the limiting strip 17, thereby supporting the movement of the connecting rod 13.

[0034] Preferably, the lower end protrusion of the locking strip 15 engages with the slots 16 opened on both sides of the lower end of the connecting rod 13, the top horizontal end of the connecting rod 13 is slidably connected to the surface of the limiting strip 17, and the surface of the limiting strip 17 is connected to the top of the front display screen of the smart meter body 1.

[0035] In practical use, the bottom protrusion of the clip 15 engages with the slots 16 on both sides of the lower end of the connecting rod 13, thereby fixing the cleaning brush 14 connected to the top of the clip 15 on the connecting rod 13. At the same time, since the protrusions on both sides of the clip 15 are made of rubber, it is also convenient to pull down and remove the clip 15 engaged with the slots 16 to replace the cleaning brush 14.

[0036] Preferably, the surface of the cleaning brush 14 is in contact with the front display screen of the smart meter body 1, and a rectangular through groove is opened horizontally on the surface of the limiting strip 17.

[0037] In practical use, the cleaning brush 14 is placed against the surface of the display screen at the front of the smart meter body 1, thereby wiping away the dirt on the surface of the display screen at the front of the smart meter body 1 under the action of the moving block 12 and the connecting rod 13. At the same time, the rectangular through groove at the front of the limiting strip 17 facilitates the restriction and support of the movement of the connecting rod 13.

[0038] Working principle: During use, the limiting block 2 and protective cover 3 connected to the front end of the mounting bracket 4 cooperate to facilitate the placement and fixation of the smart meter body 1. After the four limiting blocks 2 cooperate to abut against the four corners of the surface of the smart meter body 1, the limiting frame 6 at the front end of the smart meter body 1 is fixed by sliding against the limiting groove 5 opened horizontally at the front end of the protective cover 3. The protrusions on both sides of the limiting frame 6 are engaged and fixed in the grooves on the surface of the limiting groove 5, thereby fixing its position on the protective cover 3. Then, the pre-reserved holes and slots on the mounting bracket 4 make it convenient for users to install and fix the smart meter body 1 outdoors according to their needs. At this time, the protective cover 3 at the front end of the mounting bracket 4 protects and shields the surface of the smart meter body 1, preventing the smart meter body 1 from being directly exposed to the sun when placed outdoors, and also preventing rainwater from falling directly on the surface of the smart meter body 1 when it rains.

[0039] Furthermore, the micro motor 8 installed on the top of the limiting frame 6 can be periodically activated according to the dust conditions in the environment where the smart meter body 1 is actually used. This causes the connected lead screw 9 to rotate within the bearing 10, thereby causing the moving block 12, which is threaded onto the lead screw 9, to slide on the top of the limiting frame 6. This moves the moving block 12, which was originally located on one side of the micro motor 8, away from the micro motor 8. Consequently, the connecting rod 13, which is threaded onto the top of the moving block 12, moves on the limiting strip 17. When the connecting rod 13 moves, the end of the connecting rod that is close to the display screen of the smart meter body 1... The cleaning brush 14 is placed against the display screen of the smart meter body 1 to wipe it, thereby cleaning the dust and other impurities adhering to the surface of the display screen of the smart meter body 1. This not only prevents dust and other impurities from adhering to the surface of the display screen of the smart meter body 1 for a long time, thus avoiding affecting the accuracy of its reading, but also prevents dirt and other impurities from causing corrosion and damage to the display screen of the smart meter body 1. In addition, during use, when inspecting or maintaining the smart meter body 1, the clip 15 that is engaged with the connecting rod 13 and the slot 16 can be pulled out to remove the cleaning brush 14 that is embedded and fixed on the connecting rod 13 and replace it.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
