[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides a technical solution: a wireless SF6 density relay remote transmission device. (Please refer to...) Figure 1It includes a data acquisition device 1, which integrates a mechanical pressure gauge and an electronic sensor. The electronic part is equipped with an imported high-precision pressure sensor and a temperature sensor, supporting operation in a wide temperature range of -40℃ to +70℃, and realizing synchronous acquisition of SF6 gas density values through mechanical and electronic dual channels.
[0029] The data acquisition device 1 is equipped with a wireless transmission device 4 at the connection point. The wireless transmission device 4 has a built-in LoRa-Edge self-organizing network protocol chip, supports 4G / 5G and WAPI redundant communication links, has a communication distance of ≥1km, a standby power consumption of ≤5μA, and a data transmission frequency that can be set from 15s to 24h.
[0030] Please see Figure 2 Connecting block 2 is located at the connection end of data acquisition device 1, and positioning grooves 3 are evenly distributed on the upper and lower surfaces of connecting block 2.
[0031] The mounting box 5 is located on the connection surface of the wireless remote transmission device 4. The mounting box 5 has an installation chamber 6 inside. Please refer to [link / reference]. Figure 3 Both the front and rear sides of the inner cavity of the mounting chamber 6 are equipped with lead screws 7. Please refer to [link / reference]. Figure 4 The threads on the upper and lower parts of the lead screw 7 are opposite in direction. Adjusting blocks 8 are screwed onto both the upper and lower parts of the lead screw 7. Positioning plates 9 are installed between the adjusting blocks 8. Positioning blocks 10 are installed on the surface of the positioning plates 9 and at the corresponding positions of the positioning grooves 3.
[0032] Turntable 11 is located at the top of lead screw 7. A handle 12 is mounted on the upper surface of turntable 11. Please refer to [link / reference]. Figure 5 Gears 13 are installed inside each turntable 11. Please refer to [link / reference]. Figure 4 The outer surfaces of the gears 13 are all fitted with racks 14.
[0033] Rotating handle 12 drives turntable 11 and gear 13 to rotate. The meshing of gear 13 and rack 14 causes the two lead screws 7 to rotate synchronously, which in turn causes adjusting block 8 to move positioning plate 9. The positioning block 10 and positioning groove 3 cooperate to achieve quick connection. Disassembly can be achieved by rotating in the opposite direction. This is convenient for disassembly and assembly, and the tight cooperation between positioning block 10 and positioning groove 3 ensures the stability of the connection. It also avoids the tedious steps of repeated calibration in traditional connection methods. The rigid meshing of the mechanical structure ensures the connection strength. At the same time, the modular design allows for independent maintenance without affecting the overall function, which significantly improves the equipment debugging efficiency, operation and maintenance convenience and system reliability.
[0034] Please see Figure 3 Limiting grooves 15 are provided on both the front and rear sides of the installation chamber 6, and adjusting blocks 8 are embedded inside the limiting grooves 15, so that the positioning plate 9 can move vertically.
[0035] All lead screws 7 are located inside the limiting groove 15. The bottom end of each lead screw 7 is installed at the bottom of the inner cavity of the limiting groove 15 through bearings. The upper surface of each lead screw 7 is also connected to the upper surface of the fixed box 5 through bearings, so that the lead screw 7 can rotate stably.
[0036] Fixing clamps 16 are installed on the upper surface of the fixing box 5 at positions corresponding to the lead screw 7. Please refer to [link / reference]. Figure 6 Each opening of the fixing hoop 16 is provided with a limiting hoop 17, which can limit the lead screw 7 through the fixing hoop 16 and the limiting hoop 17.
[0037] Connecting plates 18 are installed on both the left and right sides of the fixing clamp 16 and the limiting clamp 17. Threaded rods 19 are screwed between the connecting plates 18. The threaded rods 19 can drive the limiting clamp 17 to squeeze the lead screw 7, thereby preventing the lead screw 7 from rotating.
[0038] The upper and lower parts of the inner cavity of the installation chamber 6 are equipped with baffles 20. The baffles 20 are located on the right side of the positioning plate 9. The distance between the baffles 20 is adapted to the height of the connecting block 2. The baffles 20 are used to limit the position of the connecting block 2 and prevent the position of the connecting block 2 inserted into the fixing box 5 from deviating.
[0039] When this solution is in operation: the connecting block 2 of the data acquisition device 1 is inserted into the mounting chamber 6 of the fixing box 5, and the handle 12 is turned to drive the turntable 11 and gear 13 to rotate. The gear 13 meshes with the rack 14 to make the two lead screws 7 rotate synchronously. Because the upper and lower threads of the lead screw 7 are opposite in direction, the adjusting block 8 drives the positioning plate 9 to move vertically. The positioning block 10 is embedded in the positioning groove 3 to achieve quick connection. When disassembling, simply turn the handle 12 in the opposite direction. At the same time, the baffle 20 in the mounting chamber 6 limits the connecting block 2, and the lead screw 7 is stably installed in the limiting groove 15 through the bearing. The fixing hoop 16 and the limiting hoop 17 further limit the lead screw 7 through the connecting plate 18 and the threaded rod 19 to ensure stable connection. The modular design facilitates independent maintenance.
