Description

Technical Field

[0001] The invention relates to the technical field of grounding electrodes, and in particular to a preparation process and a preparation device for a long-acting alloy fast grounding electrode. Background Art

[0002] When installing grounding devices on the tower base of a power transmission line, usually hot-dip galvanized round steel Ø 12 is used to lay rings around the tower base. When the resistance cannot meet the requirements, Ø 10-12 hot-dip galvanized round steel is used to lay rays. Generally, the buried depth is 0.6-1 meter, and 4-8 rays with a length of 30-80 meters are laid until the effective resistance is reduced. This method is difficult to implement in environments such as urban roads and farmlands, and the cost of road damage restoration or compensation for young crops is too high.

[0003] Therefore, the advantages of using vertical grounding electrodes are more obvious. For example, the patent application with publication number CN116526165A discloses a multi-umbrella-shaped vertical grounding electrode device, and the patent with announcement number CN217334423U discloses a grounding grid device. The vertical grounding electrode requires high hardness, strong corrosion resistance, and strong thermal and electrical conductivity. The vertical grounding electrode reduces resistance by discharging deep into the earth. Because the soil moisture at depth is stable and the resistance change is small, the resistance reduction effect can be guaranteed to be long-term and stable. When lightning strikes the lines and equipment, the lightning current can be quickly led to the earth to protect the safe operation of the transmission lines and equipment.

[0004] The preparation method and equipment of the long-lasting alloy grounding electrode in the vertical grounding electrode are related to the conductivity and corrosion resistance of the long-lasting alloy grounding electrode. In the prior art, the graphene solution spraying during the preparation of the long-lasting alloy grounding electrode often has the problem of uneven spraying, resulting in leakage points in the long-lasting alloy grounding electrode, thereby significantly reducing the corrosion resistance of the long-lasting alloy grounding electrode.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-14The embodiment of the present invention provides a long-acting alloy fast grounding electrode preparation device, wherein the long-acting alloy fast grounding electrode includes a steel rod and a graphene protective layer sintered on the surface of the steel rod, the steel rod includes a rod body, one end of the rod body has a plug hole, and the other end has a plug tip, the plug tip is made by rolling thread forming, and the peripheral side of the plug tip is unevenly distributed, and the long-acting alloy fast grounding electrode can be used in multiple ends, and the plug tip of one long-acting alloy fast grounding electrode is inserted into the plug hole of another long-acting alloy fast grounding electrode, and the outside is protected by an alloy conical jacket to ensure that it will not crack or separate when driven in, and it is more firm, and the contact has no resistance. During installation, only a 300*300 hole needs to be excavated at the installation location of the grounding rod to complete the construction, and the deepest depth can be 60 meters. The resistance reduction ability is very obvious, less land is occupied, and civil disputes and young crops compensation costs are reduced; no or little excavation is required, and no large-scale construction equipment is required, which effectively improves the installation efficiency, greatly saves manpower and material resources, and shortens the construction time. The first grounding electrode can be installed in conjunction with a hexagonal six-slot alloy drill bit. When in use, rock powder comes up from the six slots to penetrate the weathered rocks and rock hard materials underground.

[0037] The long-acting alloy fast grounding electrode preparation device comprises a heating furnace, a spraying chamber, a drying chamber, a sintering furnace, a cooling rack and a cleaning pool, wherein the spraying chamber is provided with a fixed base 13, a swing frame 1, a spacer frame 3 and a spraying assembly 4. The swing frame 1 is rotatably connected to the fixed base 13 via a rotating shaft 2, the rotating shaft 2 is fixedly connected to the swing frame 1 and rotatably connected to the fixed base 13, or the rotating shaft 2 is rotatably connected to the swing frame 1 and fixedly connected to the fixed base 13, the swing frame 1 is driven by a driving mechanism to swing back and forth around the rotating shaft 2, a plurality of steel rods to be sprayed with graphene solution are linearly arranged on the swing frame 1, the steel rods are parallel to each other and the ends are aligned, the steel rods are parallel to the rotating shaft 2, and the steel rods roll with the swinging of the swing frame 1.

[0038] The spacer frame 3 is connected to the swing frame 1 by movement along the arrangement direction of each steel rod. There is a spacer 3.1 between each adjacent steel rod. Each spacer 3.1 is arranged on the spacer frame 3. The spacer 3.1 keeps the distance between adjacent steel rods, which can prevent the graphene solutions on adjacent steel plates from sticking to each other. Each spacer 3.1 includes a support rod fixedly connected to the spacer frame 3 and a roller rotatably connected to the support rod. The spacer 3.1 and the steel rod are rollingly matched, and the rolling friction resistance is very small, while the sliding friction resistance between the steel rod and the swing frame 1 is relatively large, so that each steel rod keeps synchronous and sufficient rolling during the swinging process of the swing frame 1, so that the steel rods are fully and evenly sprayed with the graphene solution. The roller is made of non-stick material, such as a ball surface covered with a polytetrafluoroethylene coating, a ceramic coating or a silicone resin coating, which can prevent the roller from damaging the graphene spray layer covering the surface of the steel rod.

[0039] The driving mechanism includes a rotating wheel 5, a worm 8, a rocker arm 7 and a servo motor 6. The rotating wheel 5 specifically adopts a worm wheel, which is rotatably connected to the rocker frame 1. One end of the rocker arm 7 is rotatably connected to the fixed base 13, and the other end is eccentrically rotatably connected to the rotating wheel 5. The servo motor 6 is fixedly installed on the rocker frame 1. A worm 8 is coaxially fixedly connected to the rotating shaft of the servo motor 6. The worm 8 is meshed with the worm wheel. The driving motor drives the worm 8 to rotate, and the worm 8 drives the worm wheel to rotate. The worm wheel causes the rocker frame 1 to swing around the rotating shaft 2 through the rocker arm 7, and the steel bars on the rocker frame 1 swing together.

[0040] A reciprocating screw 9 is also provided on the swing frame 1. The reciprocating screw 9 can swing with the swing frame 1. One end of the screw rod 9.1 of the reciprocating screw 9 is coaxially fixedly connected to the rotating wheel 5, and the other end is rotatably connected to the supporting unit 1.1 of the swing frame 1. The injection assembly 4 is arranged on the slider 9.2 of the reciprocating screw 9. The injection assembly 4 is also slidably connected to the rotating shaft 2 along the length direction of the rotating shaft 2. Therefore, on the one hand, the injection assembly 4 can swing synchronously with the swing frame 1, and on the other hand, it can make reciprocating linear motion along the length direction of the steel rod under the drive of the reciprocating screw 9.

[0041] The injection assembly 4 includes a base rod 4.1, a guide rod 4.2, a sliding member slidably connected to the base rod 4.1, and a plurality of nozzles 4.5 arranged on the sliding member. The base rod 4.1 is fixedly connected to the slider 9.2 of the reciprocating screw 9, and the base rod 4.1 is slidably connected to the rotating shaft 2 through a sliding sleeve 4.7. The guide rod 4.2 is arranged on the spacer 3. The sliding member is slidably connected to the guide rod 4.2 along the length direction of the steel rod through a first connecting rod 4.8. Specifically, the sliding member includes a sliding rod 4.3 slidably connected to the base rod 4.1 and a rotating rod 4.4 rotatably connected to the sliding rod 4.3. Each nozzle 4.5 is fixedly installed on the rotating rod 4.4. An abutment rod 4.6 is fixedly connected to the swing frame 1. Each nozzle 4.5 corresponds to each steel rod one by one, and each nozzle 4.5 supplies graphene solution through a hose. Thus, when the swing frame 1 swings, each steel rod and the spacer frame 3 move relative to the swing frame 1, and the spacer frame 3 drives the spray assembly 4 to move synchronously with the spacer frame 3 in the arrangement direction of each steel rod through the sleeve 10, the second insertion rod 11, the second connecting rod 4.9, the guide rod 4.2 and the first connecting rod 4.8. Therefore, the spray assembly 4 has load movement in three directions during the spraying process, namely, following the reciprocating swing of the swing frame 1, following the reciprocating movement of the slider 9.2 of the reciprocating screw 9 along the length direction of the steel rod, and following the reciprocating movement of the spacer frame 3 along the arrangement direction of the steel rod, so that the nozzle 4.5 of the spray assembly 4 maintains a certain spraying distance with the steel rod, and moves relative to the circumferential and axial directions of the steel rod, so that the surface of the steel rod is fully and fully sprayed with the graphene solution.

[0042] During the movement of the injection assembly 4 along the length direction of the steel rod, the base rod 4.1 follows the slider 9.2 of the reciprocating screw 9 to move toward the abutment rod 4.6, so that the rotating rod 4.4 and the inclined surface of the abutment rod 4.6 are slidably matched, thereby causing the rotating rod 4.4 to rotate relative to the sliding rod 4.3, so that the injection angle of each nozzle 4.5 is changed to align with the corresponding plug-in hole of the steel rod, and the injection assembly 4 injects the graphene solution into the plug-in hole of the steel rod.

[0043] The specific structure of the swing frame 1 includes two relatively arranged supporting units 1.1 and a single frame 1.2 clamped between the two supporting units 1.1, and each steel rod is placed on the single frame 1.2. Each supporting unit 1.1 includes a frame body 1.11 and a first plug rod 1.12. The frame body 1.11 is rotatably connected to the rotating shaft 2, and the first plug rod 1.12 is slidably connected to the frame body 1.11. The first plug rod 1.12 has an insertion position inserted into a slot 1.5 on the single frame 1.2 during its sliding stroke relative to the frame body 1.11; a sleeve 10 is fixedly connected to the spacer frame 3, and a second plug rod 11 is fixedly connected to the guide rod 4.2 through a second connecting rod 4.9, and the second plug rod 11 can be plugged in and matched with the sleeve 10. This makes it easy to disassemble and assemble the swing frame 1, that is, the disassembly and assembly between the single frame 1.2 and the two supporting units 1.1. Before and after spraying the graphene solution, the single frame 1.2 between the two supporting units 1.1 can be replaced to achieve batch transfer of the steel bars into or out of the spraying chamber.

[0044] Two relatively arranged connecting units are arranged between the swing frame 1 and the spacing frame 3, each connecting unit includes a slide groove 1.3 opened on the swing frame 1, two rollers 3.2 arranged on the spacing frame 3 and an elastic telescopic rod 12, the slide groove 1.3 is connected with two inclined grooves 1.4, the two rollers 3.2 are rollingly matched with the slide groove 1.3, one end of the elastic telescopic rod 12 is fixedly connected to the single frame 1.2, and the other end is fixedly connected with a baffle 12.1, when the elastic telescopic rod 12 is extended, the baffle 12.1 abuts against the spacing frame 3 to limit the two rollers 3.2 to roll in the slide groove 1.3, which is suitable for the spacing frame 3 and each steel rod to reciprocate in the arrangement direction during the swinging process of the swing frame 1; applying external force to push the spacing frame 3 in the direction of the baffle 12.1, so that the elastic telescopic rod 12 contracts, and the two rollers 3.2 roll into the two inclined grooves 1.4 one by one, and each spacer 3.1 sinks under the swing frame 1, so as to facilitate the batch rolling of each steel rod away from the swing frame 1.

[0045] The present invention also provides a long-acting alloy fast grounding electrode preparation process, which is implemented based on the above-mentioned long-acting alloy fast grounding electrode preparation device, and includes the following steps in sequence: S1, heating each steel rod in a heating furnace to 180-200°C; S2, transferring each heated steel rod to a swing frame 1 in a spray chamber, the swing frame 1 swings back and forth to drive each steel rod to roll back and forth, and the spray assembly 4 reciprocates along the length direction of each steel rod to uniformly spray the graphene solution onto each steel rod; S3, transferring each steel rod sprayed with graphene to a drying chamber Drying in the drying room, the temperature in the drying room is 80-90℃, and the drying time is 20-25min; S4, transferring each dried steel rod to a sintering furnace for sintering and solidification, the temperature in the sintering furnace is 340-370℃, and the sintering time is 20-25min; S, transferring each sintered steel rod to the outside of the sintering furnace for cooling and cleaning to obtain a finished long-acting alloy fast grounding electrode.
