Description

Technical Field

[0001] This utility model relates to the field of torque clamps for power distribution, and particularly to aluminum alloy torque clamps for power distribution in smart grids. Background Technology

[0002] Existing aluminum alloy torque clamps are designed to provide stable electrical connections. By precisely controlling the tightening torque during installation, they ensure minimal contact resistance, thereby reducing energy loss and improving grid operating efficiency. In addition, they are easy and quick to use, helping to shorten installation time and reduce maintenance costs, which is of great significance for improving the overall performance of smart grids.

[0003] The contact surface between the clamp and the conductor may contain dirt, including dust, oxides or other contaminants, which can cause power transmission failures or safety accidents. In humid environments, these substances may absorb moisture and form an electrolyte film, further accelerating the corrosion of the contact surface and reducing conductivity. This not only impairs the stability and safety of the power grid, but also increases maintenance costs and complexity.

[0004] Therefore, in view of the problem that the contact surface between the above-mentioned clamp and the conductor may have dirt, including dust, oxides or other contaminants, which may cause power transmission failure or safety accidents, not only damaging the stability and security of the power grid, but also increasing maintenance costs and complexity, aluminum alloy torque clamps for smart grid power distribution can be designed with a pull-out cleaning device to facilitate the cleaning of dirt. Utility Model Content

[0005] To overcome the problem that dirt, including dust, oxides or other contaminants, may exist on the contact surface between the clamp and the conductor, which may cause power transmission failures or safety accidents, not only damaging the stability and security of the power grid, but also increasing maintenance costs and complexity.

[0006] The technical solution of this utility model is as follows: an aluminum alloy torque clamp for smart grid power distribution, including an upper clamp, a lower clamp, a ring, a fixing frame, and a cleaning ring. Two upper clamps are provided, and two lower clamps are movably connected to the bottom of the upper clamps. Two rings are slidably connected between the upper and lower clamps at the front position. The front end of the rings is fixedly connected to the fixing frame, and the front end of the two fixing frames is fixedly connected to a handle. The rear end of the rings is fixedly connected to two connecting rods, and the rear end of the connecting rods is fixedly connected to a cleaning ring. The cleaning ring is slidably connected to the upper clamp and the cleaning ring is slidably connected to the lower clamp. Two circular grooves are opened inside the upper clamp. Two fixing rods are fixedly connected to the upper end of the fixing frame, and a long rod is fixedly connected to the rear end of the fixing rod. The long rod is slidably connected to the circular grooves.

[0007] Preferably, by placing the cleaning ring between the upper and lower clamps and inserting the long rod into the circular groove, once the upper and lower clamps are tightened to the appropriate position, the handle is pulled to drive the cleaning ring and connecting rod to scrape and clean the inside of the upper and lower clamps. After cleaning is completed, the cleaning ring is removed.

[0008] Preferably, a high-temperature detector is fixedly connected to the bottom rear position of the lower clamp, and a pad is fixedly connected to the top of the upper clamp.

[0009] Preferably, an intermediate block is movably connected between the upper and lower clamps, and six threaded rods are slidably connected inside the intermediate block.

[0010] Preferably, the threaded rod is slidably connected to the upper clamp and to the lower clamp.

[0011] Preferably, the bottom of the threaded rod passes through the lower clamp and is fixedly connected to a limit block, and six round pads are fixedly connected to the bottom of the lower clamp corresponding to the position of the threaded rod.

[0012] Preferably, the top of the upper clamp is provided with six bolts, which are threadedly connected to the threaded rod.

[0013] Preferably, bolt 2 is provided at the top of bolt 1, and bolt 2 is threadedly connected to the threaded rod.

[0014] The beneficial effects of this utility model are:

[0015] By placing a cleaning ring between the upper and lower clamps and inserting a long rod into the circular groove, once the upper and lower clamps are tightened to the appropriate position, pulling the handle causes the cleaning ring and connecting rod to scrape and clean the inside of the upper and lower clamps. After cleaning, the cleaning ring is removed. This solves the problem that dirt, including dust, oxides, or other contaminants, may exist on the contact surface between the clamps and the conductors, which could cause power transmission failures or safety accidents, and damage the stability and safety of the power grid.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides an embodiment: an aluminum alloy torque clamp for smart grid power distribution includes an upper clamp 1, a lower clamp 2, a ring 3, a fixing frame 4, and a cleaning ring 6. Two upper clamps 1 are provided, and two lower clamps 2 are movably connected to the bottom of the upper clamp 1. Two rings 3 are slidably connected between the upper clamp 1 and the lower clamp 2 at a forward position. The front end of the ring 3 is fixedly connected to the fixing frame 4, and the front end of the two fixing frames 4 is fixedly connected to a handle 5. The rear end of the ring 3 is fixedly connected to two connecting rods 7, and the rear end of the connecting rods 7 is fixedly connected to the cleaning ring 6. The cleaning ring 6 is slidably connected to the upper clamp 1 and the lower clamp 2. The upper clamp 1 has an internal opening... Two circular grooves 9 are provided. Two fixing rods 8 are fixedly connected to the upper end of the fixing frame 4. A long rod 10 is fixedly connected to the rear end of the fixing rod 8. The long rod 10 is slidably connected to the circular groove 9. By placing the cleaning ring 6 between the upper clamp 1 and the lower clamp 2 and inserting the long rod 10 into the circular groove 9, when the upper clamp 1 and the lower clamp 2 are tightened to the appropriate position, the handle 5 is pulled to drive the cleaning ring 6 and the connecting rod 7 to scrape and clean the inside of the upper clamp 1 and the lower clamp 2. After cleaning, the cleaning ring 6 is removed. This solves the problem that dirt, including dust, oxides or other contaminants, may exist on the contact surface between the clamp and the conductor, which may cause power transmission failure or safety accidents and damage the stability and safety of the power grid.

[0023] Please see Figures 3-4 In this embodiment, a high-temperature detector 15 is fixedly connected to the bottom rear position of the lower clamp 2, and a pad 16 is fixedly connected to the top of the upper clamp 1. The high-temperature detector 15 can detect whether the torque clamp has accidentally overheated. The pad 16 fixes the two upper clamps 1 and also plays a role in preventing slippage. An intermediate block 11 is movably connected between the upper clamp 1 and the lower clamp 2. Six threaded rods 12 are slidably connected inside the intermediate block 11. The threaded rods 12 are slidably connected to the upper clamp 1 and the lower clamp 2. The lower clamp 2 and the intermediate block 11 slide on the threaded rods 12 to adapt to wires of different thicknesses.

[0024] Please see Figures 2-4In this embodiment, the bottom of the threaded rod 12 passes through the lower clamp 2 and is fixedly connected to the limiting block 13. Six round pads 14 are fixedly connected to the bottom of the lower clamp 2 corresponding to the position of the threaded rod 12. The limiting block 13 restricts the position of the threaded rod 12 on the lower clamp 2 and the middle block 11. Six bolts 17 are provided on the top of the upper clamp 1. Bolts 17 are threadedly connected to the threaded rod 12. Bolts 17 and 18 rotate on the threaded rod 12, causing the lower clamp 2 to move and clamp the wire. Bolts 18 are provided on the top of bolts 17. Bolts 18 are threadedly connected to the threaded rod 12. Bolts 18 and 17 together play a locking role.

[0025] When working, if there are stains, foreign objects, or dust inside the torque clamp, rotate bolt 17 and bolt 28 to move the threaded rod 12 and lower clamp 2 upwards. Simultaneously, place the cleaning ring 6 between the upper clamp 1 and lower clamp 2, and insert the long rod 10 into the circular groove 9. After the upper clamp 1 and lower clamp 2 are tightened to the appropriate position, pull the handle 5 to move the cleaning ring 6 and connecting rod 7 to scrape and clean the inside of the upper clamp 1 and lower clamp 2. After cleaning, remove the cleaning ring 6. When using the clamp, bolt 17 and bolt 28... Rotating on the threaded rod 12 causes the lower clamp 2 to move and clamp the wire. Bolt 2 18 and bolt 1 17 together play a locking role. By sliding the two lower clamps 2 on the threaded rod 12, it can accommodate two different wires of different thicknesses at the same time. The limiting block 13 restricts the position of the threaded rod 12 on the lower clamp 2 and the middle block 11. At the same time, the round pad 14 plays a role in anti-slip locking. The high temperature detector 15 at the bottom of the lower clamp 2 can detect whether the torque clamp has accidentally overheated. The pad 16 fixes the two upper clamps 1 and also plays a role in anti-slip.

[0026] Through the above steps, the cleaning ring 6 is placed between the upper clamp 1 and the lower clamp 2, and the long rod 10 is inserted into the circular groove 9. After the upper clamp 1 and the lower clamp 2 are tightened to the appropriate position, the handle 5 is pulled to drive the cleaning ring 6 and the connecting rod 7 to scrape and clean the inside of the upper clamp 1 and the lower clamp 2. After cleaning, the cleaning ring 6 is removed to solve the problem that there may be dirt, including dust, oxides or other contaminants, on the contact surface between the clamp and the conductor. These substances may absorb moisture and form an electrolyte film in a humid environment, further accelerating the corrosion of the contact surface, reducing conductivity, and causing power transmission failures or safety accidents, which may damage the stability and safety of the power grid.
