Description

Technical Field

[0001] This utility model relates to the field of lightning rod technology, and in particular to a lightning rod installation device for power transmission towers. Background Technology

[0002] A lightning rod, also known as a lightning arrestor or lightning rod, is a device used to protect buildings, tall trees, and other structures from lightning strikes. When a thundercloud discharges, a localized electric field is concentrated at the top of the lightning rod, influencing the direction of the lightning leader discharge and guiding the lightning to discharge towards the lightning rod. The lightning current is then conducted to the ground through the grounding down conductor and grounding device, thus protecting the object from lightning strikes.

[0003] Transmission towers are generally truss structures made of angle steel. As important power facilities, their height makes them highly susceptible to absorbing lightning strikes during thunderstorms, which can damage transmission lines and cause major safety accidents. Therefore, lightning rods need to be installed at the top of the transmission towers. The conventional method for installing lightning rods on transmission towers is to erect a frame at the top of the tower and then fix the lightning protection device to the frame. Due to the varying widths of the frame, installation is relatively complicated; for transmission towers without frame frames, installation is even more difficult.

[0004] Therefore, it is necessary to provide a lightning rod installation device for power transmission towers to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a lightning rod installation device for power transmission towers.

[0006] This utility model provides a lightning rod installation device for power transmission towers, comprising: an installation plate, the bottom of which is provided with a plurality of first movable grooves and second movable grooves, the first movable grooves and second movable grooves being slidably connected to the upper ends of a first fixed plate and a second fixed plate, the inner surfaces of the first movable grooves and second movable grooves being provided with a first limiting hole and a second limiting hole, the first limiting hole and the second limiting hole being threaded with a first limiting shaft and a second limiting shaft, the top of which is provided with an installation groove connected to the bottom of the lightning rod, and the center of the installation groove being provided with a cable hole for the lightning rod cable to pass through.

[0007] Preferably, the bottom end of the mounting groove is provided with multiple connection holes.

[0008] Preferably, a first fixing pad and a second fixing pad are respectively bonded to the opposite sides of the first fixing plate and the second fixing plate, and the first fixing pad and the second fixing pad are made of rubber.

[0009] Preferably, the top of the first moving slot and the second moving slot are respectively provided with a first pulling hole and a second pulling hole. The first pulling hole is slidably connected to a first pulling rod, and the bottom of the first pulling rod is connected to the top of the first fixed plate. The second pulling hole is slidably connected to a second pulling rod, and the bottom of the second pulling rod is connected to the top of the second fixed plate.

[0010] Preferably, the end of the first limiting shaft facing the first fixing plate is connected to a circular first limiting plate, and the end of the second limiting shaft facing the second fixing plate is connected to a circular second limiting plate.

[0011] Preferably, the mounting plate has a first protective groove and a second protective groove on its two sides, the first limiting hole is located inside the first protective groove, the second limiting hole is located inside the second protective groove, the first protective groove is slidably connected to one end of the first protective box, and the second protective groove is slidably connected to one end of the second protective box.

[0012] Preferably, a first protective pad and a second protective pad are bonded to the inner surfaces of the first protective groove and the second protective groove, and the first protective pad and the second protective pad are made of rubber.

[0013] Compared with related technologies, the lightning rod installation device for power transmission towers provided by this utility model has the following advantages: This invention involves manually moving the first and second fixing plates until their sides abut against the upper sides of the transmission tower. Then, by rotating the first and second limiting shafts, the first and second limiting shafts are moved towards the first and second fixing plates until they abut against the sides of both plates. This contact between the first and second limiting shafts achieves the fixing and limiting of the first and second fixing plates, allowing the mounting plate to be snapped onto the upper end of the transmission tower. This eliminates the need to consider the width of the mounting plate, improving installation convenience. Furthermore, the use of movable first and second fixing plates makes the device suitable for different transmission towers, enhancing its applicability. This utility model, by setting a first pulling rod and a second pulling rod, allows the first fixed plate and the second fixed plate to move back and forth in the corresponding moving slot by holding the first pulling rod and the second pulling rod. The entire operation can be completed above the mounting plate without having to go around to the side of the mounting plate to operate, thus improving the convenience and safety of operation. This utility model provides protection for the first and second limiting shafts by setting up a first protective box that is slidably connected to the first protective groove and a second protective box that is slidably connected to the second protective groove. After adjustment, the first and second protective boxes are installed to protect the first and second limiting shafts from prolonged direct contact with the outside environment, which could cause corrosion of the first and second limiting shafts. Furthermore, by setting up the first and second protective pads, the friction between the first and first protective grooves and the first protective box, as well as the friction between the second protective groove and the second protective box, can be increased, thereby improving the stability of the connection between the first and second protective boxes.

[0017] In the embodiments of this utility model, reference is made to Figure 1 As shown, the bottom end of the mounting groove 2 is provided with multiple connection holes 4.

[0018] It should be noted that during use, the mounting plate 1 can be placed on the upper end of the transmission tower, with the upper end of the transmission tower positioned between the first fixing plate 12 and the second fixing plate 15. Then, by manually moving the first fixing plate 12 and the second fixing plate 15, their sides are brought into contact with the two sides of the upper end of the transmission tower. Next, by rotating the first limiting shaft 18 and the second limiting shaft 16, the first limiting shaft 18 and the second limiting shaft 16 are positioned towards the first fixing plate 12 and the second fixing plate 15, respectively. The device moves until the first limiting shaft 18 abuts against the side of the first fixing plate 12, and the second limiting shaft 16 abuts against the side of the second fixing plate 15. Through the abutment of the first limiting shaft 18 and the second limiting shaft 16, the first fixing plate 12 and the second fixing plate 15 are fixed and limited, thereby snapping the mounting plate 1 onto the upper end of the transmission tower. There is no need to consider the width of the mounting plate, which improves the convenience of installation. Furthermore, the use of movable first fixing plate 12 and second fixing plate 15 makes it applicable to different transmission towers, thus improving the applicability of the device.

[0019] In the embodiments of this utility model, reference is made to Figure 2 , Figure 3 As shown, a first fixing pad 13 and a second fixing pad 20 are respectively bonded to the opposite sides of the first fixing plate 12 and the second fixing plate 15. The first fixing pad 13 and the second fixing pad 20 are made of rubber.

[0020] It should be noted that by setting the first fixing pad 13 and the second fixing pad 20 made of rubber material, the pressure on the upper end of the transmission tower connected to the fixing plate can be reduced, preventing excessive pressure from damaging the upper end of the transmission tower.

[0021] In the embodiments of this utility model, reference is made to Figure 1As shown, the top of the first moving groove 11 and the second moving groove 14 are respectively provided with a first pulling hole 5 and a second pulling hole 7.

The second pulling hole 7 is slidably connected to the second pulling rod 8, and the bottom of the second pulling rod 8 is connected to the top of the second fixing plate 15.

[0022] It should be noted that by setting the first pull rod 6 and the second pull rod 8, the first fixed plate 12 and the second fixed plate 15 can be moved back and forth in the corresponding moving slots by holding the first pull rod 6 and the second pull rod 8. The entire operation can be completed above the mounting plate 1 without having to go around to the side of the mounting plate 1 to operate, which improves the convenience and safety of operation.

[0024] It should be noted that by setting the first limiting plate 19 and the second limiting plate 17 in a circular shape, the area at the connection between the first limiting shaft 18 and the second limiting shaft 16 and the corresponding fixed plate is increased, thereby improving the stability of the limiting of the first fixed plate 12 and the second fixed plate 15.

[0025] In the embodiments of this utility model, reference is made to Figure 4 , Figure 5 As shown, the mounting plate 1 has a first protective groove 21 and a second protective groove 24 on its two sides respectively. The first limiting hole 22 is located inside the first protective groove 21, and the second limiting hole 23 is located inside the second protective groove 24. The first protective groove 21 is slidably connected to one end of the first protective box 9, and the second protective groove 24 is slidably connected to one end of the second protective box 10.

[0026] In an embodiment of this utility model, a first protective pad and a second protective pad are bonded to the inner surfaces of the first protective groove 21 and the second protective groove 24, and the first protective pad and the second protective pad are made of rubber.

[0027] It should be noted that by setting a first protective box 9 that is slidably connected to the first protective groove 21 and a second protective box 10 that is slidably connected to the second protective groove 24, after adjustment, the first protective box 9 and the second protective box 10 are installed to protect the first limiting shaft 18 and the second limiting shaft 16, preventing them from being in direct contact with the outside world for a long time and causing corrosion of the first limiting shaft 18 and the second limiting shaft 16. By setting the first protective pad and the second protective pad, the friction between the first protective groove 21 and the first protective box 9 and the friction between the second protective groove 24 and the second protective box 10 can be increased, thereby improving the stability of the connection between the first protective box 9 and the second protective box 10.

[0028] The working principle of the lightning rod installation device for power transmission towers provided by this utility model is as follows: By manually moving the first fixing plate 12 and the second fixing plate 15, the sides of the first fixing plate 12 and the second fixing plate 15 are brought into contact with the upper sides of the transmission tower, respectively. Then, by rotating the first limiting shaft 18 and the second limiting shaft 16, the first limiting shaft 18 and the second limiting shaft 16 are moved towards the first fixing plate 12 and the second fixing plate 15, respectively, until the first limiting shaft 18 and the second limiting shaft 16 are in contact with the side of the first fixing plate 12 and the side of the second fixing plate 15, respectively. Through the contact of the first limiting shaft 18 and the second limiting shaft 16, the first fixing plate 12 and the second fixing plate 15 are fixed and limited, and the mounting plate 1 is then snapped onto the upper end of the transmission tower. There is no need to consider the width of the mounting plate, which improves the convenience of installation.
