Description

Technical Field

[0001] The present invention relates to the field of electric pole reinforcement, and in particular to an adjustable electric pole reinforcement device for a power distribution line. Background Art

[0002] Distribution lines are crucial energy infrastructure, and their operational safety is crucial. Most distribution line poles are installed outdoors or in areas with soft, sticky, and sandy soil. Under the influence of wind, rain, or natural disasters, the foundations of the poles can easily become loose and unstable, causing the poles to tilt or even fall. Once a tilted pole collapses, it can cause widespread power outages, seriously threatening the normal power supply.

[0003] Existing pole reinforcement technology solutions often use conventional guy wire structures, with the upper end clamped to hold the pole tightly and adding protective guy wires in multiple directions of the pole. However, in strong wind areas, coastal areas, areas prone to extreme weather and unstable geological conditions, poles are prone to unstable reinforcement due to uneven force, causing the poles to topple over and affecting the supply of electricity. Summary of the Invention

[0005] The technical solution of the present invention is: an adjustable pole reinforcement device for distribution lines, including three bases, all of which are fixedly connected to ground nails, the ground nails are used to fix the bases, each of the bases is provided with a lifting and adjusting mechanism, the lifting and adjusting mechanism is used to adjust the support height of the pole, the lifting and adjusting mechanism is provided with a clamping mechanism, the clamping mechanism is used to clamp and limit the pole.

[0006] Furthermore, the lifting and adjusting mechanism includes a fixed guide rod, the three bases are fixedly connected to a fixed guide rod, the fixed guide rod is provided with a plurality of clamping holes, the three fixed guide rods are slidably connected to a lifting hollow rod, each of the lifting hollow rods is provided with a through hole corresponding to the plurality of clamping holes of the fixed guide rod, the through holes at the bottom of the three lifting hollow rods and the clamping holes at the bottom of the three fixed guide rods are penetrated by bolts, and the three bolts are threaded with nuts.

[0007] Furthermore, the clamping mechanism includes a guide rod, the upper parts of the three lifting hollow rods are slidably connected to the guide rod, the ends of the three guide rods close to each other are fixedly connected to an arc seat, a threaded hole is opened at the bottom of the arc seat, and a rotating screw is rotatably connected to the middle part of the arc seat, the lifting hollow rod is threadedly connected to the rotating screw, the ends of the three rotating screws away from the arc seat are fixedly connected to a fixed gear rod, the three fixed gear rods are slidably connected to the transmission bevel gear, the three lifting hollow rods are rotatably connected to the adjusting screw, the upper parts of the three adjusting screws are fixedly connected to the power bevel gear, and the power bevel gear is meshed with the transmission bevel gear.

[0008] Furthermore, it also includes an extension limit mechanism. The arc-shaped seat is provided with an extension limit mechanism, and the extension limit mechanism is used to enhance the limitation of the electric pole. The extension limit mechanism includes a rotating rod, and the lower part of each rotating rod is fixedly connected to two limit rings, and a clamping seat is clamped between the two limit rings.

[0009] Furthermore, it also includes an angle limiting mechanism, which is used to limit the clamping seat, each of the lifting hollow rods is provided with two vertical slots, and each of the two vertical slots of the lifting hollow rod is slidably connected to a lifting plate, and the two lifting plates are threadedly connected to the adjusting screw, and each lifting plate is rotatably connected to a movable limiting rod on the side close to the rotating rod, and the clamping seat is fixedly connected to a fixed extrusion seat on the side close to the lifting hollow rod, and the ends of the two movable limiting rods away from the lifting plates approach each other and contact the fixed extrusion seat, forming a triangular angle between the two lifting plates and the two movable limiting rods and the fixed extrusion seat.

[0010] Furthermore, it also includes a first clamping plate, one side of each of the arc seats and each of the clamping seats is fixedly connected to the first clamping plate, and the other side of each of the arc seats and each of the clamping seats is fixedly connected to a second clamping plate.

[0011] The beneficial effects are: 1. The staff adjusts the corresponding positions of the through hole of the lifting hollow rod and the clamping hole of the fixed guide rod according to the height of the terrain, and then inserts the bolt into the through hole of the lifting hollow rod and the clamping hole of the fixed guide rod, and twists the nut on the bolt to limit and fix the lifting hollow rod, so that the three arc seats can be kept in the same plane to limit the pole under different terrains. Then the worker turns the adjusting screw in turn, and the rotation of the adjusting screw drives the power bevel gear to rotate, and the power bevel gear drives the transmission bevel gear, the fixed gear rod and the rotating screw to rotate. The rotating screw pushes the arc seat to move in the direction away from the lifting hollow rod, and the arc seat is tightly fitted with the pole.

[0012] 2. The worker first aligns the rotating rod, limiting ring and clamping seat with the threaded hole at the bottom of the arc seat, and then rotates the rotating rod into the threaded hole at the bottom of the arc seat. The rotating rod and limiting ring drive the clamping seat to move upward. When the arc seat moves in the direction away from the lifting hollow rod, it also drives the rotating rod, limiting ring and clamping seat to move together. When the three arc seats limit and fix the pole, the three clamping seats limit and fix the lower part of the pole, thereby enhancing the reinforcement effect of the pole.

[0013] 3. The rotating screw drives the two lifting plates to move toward each other. The movement of the two lifting plates toward each other makes the angle between the two movable limit rods smaller. The angle generated by the two movable limit rods squeezes the fixed extrusion seat, so that the clamping seat can maintain the limited clamping of the pole, thereby improving the stability of the three clamping seats in limiting and fixing the lower part of the pole.

DETAILED DESCRIPTION

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

[0022] Example 1: An adjustable pole reinforcement device for a distribution line, such as Figure 1-5 As shown, it includes three bases 1, and the three bases 1 are fixedly connected with ground nails 2, and the ground nails 2 are used to fix the bases 1. Each base 1 is provided with a lifting adjustment mechanism 3, and the lifting adjustment mechanism 3 is used to adjust the support height of the pole. The lifting adjustment mechanism 3 is provided with a clamping mechanism 4, and the clamping mechanism 4 is used to clamp and limit the pole.

[0023] The lifting adjustment mechanism 3 includes a fixed guide rod 31, and the three bases 1 are welded with a fixed guide rod 31. The fixed guide rod 31 is provided with a plurality of clamping holes. The three fixed guide rods 31 are slidably connected with a lifting hollow rod 32. Each of the lifting hollow rods 32 is provided with a through hole corresponding to the plurality of clamping holes of the fixed guide rod 31. Bolts 33 are passed through the through holes at the bottom of the three lifting hollow rods 32 and the clamping holes at the bottom of the three fixed guide rods 31. The bolts 33 are used to clamp the lifting hollow rod 32 and the fixed guide rod 31. The three bolts 33 are threadedly connected with nuts 34.

[0024] The clamping mechanism 4 includes a guide rod 41, and the upper parts of the three lifting hollow rods 32 are slidably connected to the guide rod 41, and the ends of the three guide rods 41 close to each other are welded with an arc seat 42, and the arc seat 42 is used to clamp and limit the pole, and a threaded hole is opened at the bottom of the arc seat 42, and the middle part of the arc seat 42 is rotatably connected to a rotating screw 43, and the lifting hollow rod 32 is threadedly connected to the rotating screw 43, and the ends of the three rotating screws 43 away from the arc seat 42 are welded with a fixed gear rod 44, and the three fixed gear rods 44 are slidably connected to the transmission bevel gear 45, and the three lifting hollow rods 32 are rotatably connected to the adjusting screw 46, and the upper parts of the three adjusting screws 46 are fixedly connected to the power bevel gear 47, and the power bevel gear 47 is meshed with the transmission bevel gear 45.

[0025] When the pole needs to be reinforced, the staff finds the location for the three bases 1. If one of the locations is low in terrain, the staff puts the lifting hollow rod 32 and the arc seat 42 on the fixed guide rod 31 on the base 1, and adjusts the position of the through hole of the lifting hollow rod 32 and the corresponding hole of the fixed guide rod 31 according to the height of the terrain. Then, the bolt 33 is inserted into the through hole of the lifting hollow rod 32 and the hole of the fixed guide rod 31, and the nut 34 is twisted on the bolt 33 to limit and fix the lifting hollow rod 32, thereby achieving The three arc-shaped seats 42 can be kept in the same plane to limit the position of the electric pole under different terrains. Then the workers insert the ground nails 2 into the three bases 1 to fix the bases 1. Then the workers turn the adjusting screw 46 in turn. The rotation of the adjusting screw 46 drives the power bevel gear 47 to rotate. The power bevel gear 47 drives the transmission bevel gear 45, the fixed gear rod 44 and the rotating screw 43 to rotate. Through the thread of the lifting hollow rod 32, the rotating screw 43 drives the fixed gear rod 44 to move in the direction away from the power bevel gear 47. The rotating screw 43 pushes the arc seat 42 to move in the direction away from the lifting hollow rod 32, and the arc seat 42 fits tightly with the pole. After the other two adjusting screws 46 are rotated, the three arc seats 42 fit tightly with the pole. The worker rotates the adjusting screw 46 on the ground to make the three arc seats 42 limit and fix the pole, thereby more conveniently limiting and fixing the pole. When the pole does not need to be reinforced and needs to be dismantled, the worker rotates the three adjusting screws 46 in turn to reverse, and the adjusting screw 46 drives the rotating screw 43. The fixed gear rod 44 and the transmission bevel gear 45 are reset together. The rotating screw 43 is reset to drive the arc seat 42 to reset in the direction close to the lifting hollow rod 32. The arc seat 42 is disengaged from the pole. When the three arc seats 42 are disengaged from the pole, the worker twists the nut 34, the nut 34 is disengaged from the bolt 33, and then the bolt 33 is removed. The bolt 33 no longer jams the lifting hollow rod 32 and the fixed guide rod 31. The worker removes the lifting hollow rod 32 from the fixed guide rod 31, and finally pulls the ground nail 2 out of the base 1.

[0026] Example 2: Based on Example 1, Figure 1 、 Figure 2 and Figure 6 As shown, an extension limiting mechanism 5 is also included. The arc-shaped seat 42 is provided with an extension limiting mechanism 5. The extension limiting mechanism 5 is used to enhance the limitation of the electric pole. The extension limiting mechanism 5 includes a rotating rod 51. Two limiting rings 52 are welded to the lower part of each rotating rod 51. A clamping seat 53 is clamped between the two limiting rings 52. The clamping seat 53 is used to limit the lower part of the electric pole, and the limiting ring 52 is used to limit the clamping seat 53.

[0027] When the pole needs to be reinforced, the worker first aligns the rotating rod 51, the limiting ring 52 and the clamping seat 53 with the threaded hole at the bottom of the arc seat 42, and then rotates the rotating rod 51 into the threaded hole at the bottom of the arc seat 42. The rotating rod 51 and the limiting ring 52 drive the clamping seat 53 to move upward. When the arc seat 42 moves in the direction away from the lifting hollow rod 32, it also drives the rotating rod 51, the limiting ring 52 and the clamping seat 53 to move together. When the three arc seats 42 limit and fix the pole, the three clamping seats 53 limit and fix the lower part of the pole, thereby enhancing the reinforcement effect of the pole. When the reinforcement of the pole needs to be dismantled, the worker rotates the rotating rod 51, and the rotating rod 51 and the limiting ring 52 drive the clamping seat 53 to disengage from the threaded hole at the bottom of the arc seat 42.

[0028] Example 3: Based on Example 2, Figure 1-Figure 3 As shown, it also includes an angle limiting mechanism 6, which is used to limit the clamping seat 53. Each of the lifting hollow rods 32 is provided with two vertical slots, and each of the two vertical slots of the lifting hollow rod 32 is slidably connected with a lifting plate 61. The two lifting plates 61 are threadedly connected to the adjusting screw 46. Each lifting plate 61 is rotatably connected to a movable limiting rod 62 on the side close to the rotating rod 51. A fixed extrusion seat 63 is welded to the side of the clamping seat 53 close to the lifting hollow rod 32. The ends of the two movable limiting rods 62 away from the lifting plates 61 approach each other and contact the fixed extrusion seat 63, and a triangular angle is formed between the two lifting plates 61 and the two movable limiting rods 62 and the fixed extrusion seat 63.

[0029] Due to the guiding effect of the lifting hollow rod 32, the rotating screw 43 rotates and drives the two lifting plates 61 to move toward each other. The movement of the two lifting plates 61 toward each other makes the angle between the two movable limiting rods 62 smaller, and the angle generated by the two movable limiting rods 62 squeezes the fixed extrusion seat 63, so that the clamping seat 53 can maintain the limited clamping of the pole, thereby improving the stability of the three clamping seats 53 in limiting and fixing the lower part of the pole. When it is necessary to remove the reinforcement of the pole, the adjusting screw 46 is reversed to drive the two lifting plates 61 to reset. The resetting of the two lifting plates 61 makes the angle between the two movable limiting rods 62 larger, and the two movable limiting rods 62 no longer squeeze the fixed extrusion seat 63 and the clamping seat 53.

[0030] Example 4: Based on Example 3, Figure 6 As shown, a first snap-fit ​​plate 71 is also included. The first snap-fit ​​plate 71 is welded to one side of each of the arc-shaped seats 42 and each of the clamping seats 53 , and a second snap-fit ​​plate 72 is welded to the other side of each of the arc-shaped seats 42 and each of the clamping seats 53 .

[0031] When the three arc-shaped seats 42 are close to each other to limit and fix the pole, the first snap-fit ​​plate 71 and the second snap-fit ​​plate 72 between the arc-shaped seats 42 are snap-fitted. Through the first snap-fit ​​plate 71 and the second snap-fit ​​plate 72, the three arc-shaped seats 42 can restrict each other in the face of strong winds, so that the three arc-shaped seats 42 maintain sufficient stability, thereby further improving the reinforcement effect of the pole. When the three arc-shaped seats 42 are out of contact with the pole, the first snap-fit ​​plate 71 and the second snap-fit ​​plate 72 are also out of contact.
