Detailed Embodiment

[0026] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0027] Embodiment 1: As shown in Attached Figure 1 to Attached Figure 5 shown, a distribution network frame includes a utility pole 1, a wire - stringing mechanism, an adjustment mechanism, a monitoring and alarm mechanism, etc.

[0028] The utility pole 1 is erected on the ground, its cross - section is circular, and its cross - sectional area gradually decreases from bottom to top.

[0029] The wire erection mechanism is connected to the utility pole 1 and is arranged at the upper part of the utility pole 1, and it is used for erecting wires. The wire erection mechanism includes a fixing ring 2, a fixing box 3 and several groups of wire clamping members. The fixing ring 2 is sleeved on the utility pole 1, and on the fixing ring 2, for example, on its front and back surfaces, screw sleeves are embedded. The inner cavity of the screw sleeve is threadedly connected with a lead screw 14. And a plurality of longitudinally arranged limit buckles 15 are embedded on the utility pole 1. Thus, the fixing ring 2 is connected to the utility pole 1 through the lead screw 14 that cooperates with the limit buckle 15, that is, one end of the lead screw 14 penetrates into the inner cavity of the fixing ring 2 and cooperates with the limit buckle 15 to fix the fixing ring 2 and prevent the fixing ring 2 from moving up and down on the surface of the utility pole 1. Two fixing boxes 3 are symmetrically connected to both sides of the fixing ring 2, and the outer shape of the fixing box 3 is a cuboid. The wire clamping members are arranged on the upper surface of the fixing box 3 and are horizontally arranged. Each group of wire clamping members includes a fixed clamping seat 4 fixedly arranged on the fixing box 3 and a movable clamping seat 5 connected to the fixed clamping seat 4. A threading space for fixing the wire is formed between the fixed clamping seat 4 and the movable clamping seat 5. One end of the fixed clamping seat 4 and the movable clamping seat 5 is hinged through a hinge, and the other end is connected through a bolt.

[0030] The adjustment mechanism is used to movably connect the utility pole 1 and the wire erection mechanism to adjust the state of the wire erection mechanism. The adjustment mechanism includes a movable block 7, a support rod 8 and a buckle 9. The movable block 7 is movably connected to the fixing box 3 through a moving mechanism 6, and two movable blocks 7 are correspondingly arranged for the two fixing boxes 3. Two support rods 8 are arranged, corresponding to the two movable blocks 7 respectively. One end of the support rod 8 is rotatably connected to the movable block 7 through a movable seat, and the other end of the support rod 8 is rotatably connected to the buckle 9 through a movable seat. The buckle 9 is arranged on the utility pole 1 and includes two butted monomers, and the ends of the monomers are fixedly connected through bolts, so that the utility pole 1 is fixed in the inner cavity formed by the two monomers.

[0031] The monitoring and alarm mechanism is used to detect the state of the utility pole 1 or the wire erection mechanism and alarm when the utility pole 1 or the wire erection mechanism is tilted. The monitoring and alarm mechanism includes a fixing box 10, a pendulum, a sensor and an alarm. The fixing box 10 is connected to the fixing ring 2 and is located at the top of the utility pole 1, and the top end of the utility pole 1 is inserted into the fixing box 10. The pendulum is suspended in the fixing box 10 through a rope, so it can swing relative to the fixing box 10. The sensor is arranged in the fixing box 10 and is used to detect the swinging state of the pendulum and send a warning signal when the pendulum swings to a specified position. The alarm is arranged outside the fixing box 10 and is signal-connected to the sensor, so it alarms based on the warning signal. The sensor can also communicate with the monitoring room, so as to send the warning signal to the monitoring room. In this embodiment, the pendulum adopts a movable ball 11, the sensor adopts a pressure sensor 12 arranged on the swinging path of the pendulum, and two pressure sensors 12 are arranged, respectively on both sides of the pendulum. The alarm adopts a flash lamp 13.

[0032] The moving mechanism 6 is mainly arranged in the fixed box 3, and this moving mechanism 6 is arranged in each fixed box 3. The moving mechanism 6 includes a worm, a worm gear, a turntable and a rack plate. The worm is rotatably installed in the fixed box 3, that is, its two ends are respectively installed on both sides of the inner cavity of the fixed box 3 through bearings. The turntable is connected to the worm and is arranged on the side of the fixed box 3 away from the fixed ring 2, and the worm can be operated to rotate through the turntable. A rotating shaft is fixed at the center of the worm gear, and the two ends of the rotating shaft are respectively installed on both sides of the inner cavity of the fixed box 3 through bearings, so that the worm gear is rotatably installed in the fixed box 3, and the worm gear meshes with the worm from below. The rack plate is movably arranged in the fixed box 3 and meshes with the worm gear from below. The bottom of the rack plate is fixedly connected to the corresponding movable block 7, and a sliding through hole is opened at the bottom of the fixed box 3, and the movable block 7 passes through the sliding through hole and is connected to the rack plate. A chute 22 is opened on the inner bottom surface of the fixed box 3, and a slider 23 is slidably arranged in the chute 22, and the slider 23 is connected to the rack plate.

[0033] An activity plate 16 is arranged in the fixed box 10, and the activity plate 16 is connected to the top end of the electric pole 1. A limit groove 21 is opened at the center of the bottom surface of the activity plate 16, and the top end of the electric pole 1 is inserted into the limit groove 21. A plurality of first springs 17 are arranged between the bottom surface of the activity plate 16 and the inner bottom surface of the fixed box 10, that is, the bottom of the first spring 17 is fixedly arranged on the inner cavity bottom surface of the fixed box 10, and the top is fixedly arranged on the bottom surface of the activity plate 16, and the first springs 17 are arranged around the electric pole 1.

[0034] Grooves are sequentially opened from top to bottom on both side walls, the front surface and the back surface of the inner cavity of the fixed box 10. A plurality of movable limit blocks 18 are arranged in the grooves on the inner side wall of the fixed box 10. The movable limit blocks 18 are connected to the fixed box 10 through movable shafts. The distances from the outer edges of the limit blocks to the center of the movable shafts are not equal and form chamfers, so as to rotate to a specified position. The side part of the activity plate 16 is in contact with the inner side wall of the fixed box 10 and is limited by the movable limit blocks 18 rotated to the specified position.

[0035] A plurality of limit rods 19 are also arranged in the fixed box 10, and the limit rods 19 are also arranged around the electric pole 1. The bottom of the limit rod 19 is fixed on the inner bottom surface of the fixed box 10, and the upper part passes through the activity plate 16. A fixed block is arranged at the top of the limit rod 19, and a second spring 20 is arranged between the upper surface of the activity plate 16 and the bottom of the fixed block at the top end of the limit rod 19, and the second spring 20 is wound on the surface of the limit rod 19.

[0036] After the above distribution network framework inclines, the fixed ring 2 drives the fixed box 10 to incline. Subsequently, the movable ball 11 remains vertical in the vertical direction. The movable ball 11 presses against the pressure sensor 12. Then, the pressure sensor 12 sends a warning signal to the monitoring room, and then turns on the flash lamp 13 to give an alarm, facilitating the maintenance personnel to locate the position of the electric pole 1. At the same time, the inclination of the electric pole 1 can be monitored. Through the cooperation of the support rod 8 and the buckle 9, the position of the fixed box 3 is adjusted to ensure that the fixed box 3 remains horizontal, avoiding different extrusion forces on the fixed box 3 from both sides of the wires when the fixed clamping seat 4 and the movable clamping seat 5 fix the wires, resulting in the inclination of the fixed ring 2 and affecting the safety of the wire power transmission. Through the moving mechanism 6, it is convenient to adjust the angle of the support rod 8, facilitating the support rod 8 to support the fixed box 3 and keeping the fixed box 3 horizontal, avoiding the situation that the two fixed boxes 3 are not on the same horizontal plane, causing the electric pole 1 to incline. Through the cooperation of the screw sleeve, the lead screw 14 and the limit buckle 15, the fixed ring 2 is fixed to prevent the fixed ring 2 from moving up and down on the surface of the electric pole 1, ensuring the stability of the fixed box 3. The first spring 17 drives the movable plate 16 to move downward, making the movable plate 16 tightly contact the top of the electric pole 1 to limit the fixed ring 2 and prevent the fixed ring 2 from shaking. At the same time, the stability of the fixed ring 2 on the surface of the electric pole 1 is ensured. Through the cooperation of the groove and the limit block, it is convenient to limit the movable plate 16 and prevent the movable plate 16 from moving downward, ensuring the stability of the movable plate 16. Through the cooperation of the limit rod 19, the movable plate 16 is limited to prevent the movable plate 16 from shaking and improving the stability of the movable plate 16. Through the cooperation of the fixed block and the second spring 20, the movable plate 16 is pressed, facilitating the limitation of the electric pole 1 by the movable plate 16 and ensuring the stability of the fixed ring 2. Through the cooperation of the limit groove 21, the electric pole 1 is limited to prevent the electric pole 1 from sliding at the bottom of the movable plate 16, causing the fixed box 10 to incline and making the two fixed boxes 3 on both sides of the fixed ring 2 not on the same horizontal plane, unable to ensure the limiting effect of the fixed clamping seat 4 and the movable clamping seat 5 on the wires. Through the cooperation of the chute 22 and the slider 23, it is convenient to fix and limit the rack plate, preventing the rack plate from shaking in the inner cavity of the fixed box 3 and requiring the position of the movable block 7, resulting in the support rod 8 being unable to effectively support the fixed box 3 stably and easily causing the fixed box 3 to shake. Through the setting of the shape of the electric pole 1, it is convenient to fix the fixed ring 2 and the buckle 9. Utilizing the extrusion force of the wire on the fixed box 3, the buckle 9 is tightly fixed on the surface of the electric pole 1, facilitating the support of the fixed box 3.

[0037] During specific use, when the utility pole 1 is tilted or the fixing ring 2 is tilted, the fixing ring 2 drives the fixing box 10 to tilt. Subsequently, the movable ball 11 remains vertical through the fixation of the rope. Then, the movable ball 11 presses against the tilted pressure sensor 12. Subsequently, the pressure sensor 12 is squeezed and simultaneously transmits an electrical signal to notify the maintenance personnel. At the same time, the flash lamp 13 is turned on. Subsequently, the flash lamp 13 lights up, enabling the maintenance personnel coming for repair to quickly locate. When the maintenance personnel climb to the top of the utility pole 1, they rotate the turntable. Subsequently, the turntable drives the worm to rotate. At the same time, the rotation of the worm drives the worm gear to rotate. Subsequently, the worm gear drives the rack plate to move left and right. At the same time, the rack plate drives the movable block 7 to move left and right. Then, the movable block 7 drives the support rod 8 to move. At the same time, the angle of the support rod 8 is adjusted. Through the cooperation of the buckle 9, the fixing box 3 is supported and the level of the fixing box 3 is adjusted. Subsequently, the fixing box 3 drives the fixing ring 2 to rotate. At the same time, the fixing ring 2 drives the fixing box 10 to return to the horizontal position. Subsequently, the maintenance personnel use the equipment to detect the horizontal angle of the fixing box 3 to ensure the stability of the fixing box 3. At this time, since the fixing box 10 is restored, the movable ball 11 is between the pressure sensors 12 and cannot trigger the pressure sensor 12. At the same time, the flash lamp 13 is turned off.
