Description

Technical Field

[0001] The present application relates to the technical field of installation of power transmission equipment, and in particular to a power tower that is convenient for installing cables. Background Art

[0002] The iron tower is the support point of the overhead line. If one circuit is installed on the transmission tower, it is a single-circuit transmission tower. If two circuits are installed on the transmission tower, it is a double-circuit transmission tower.

[0003] In power transmission systems, towers serve as crucial support and transmission infrastructure. The quality of cable connector installation directly impacts the safe operation of the entire power grid. Cable connectors are a crucial component of overhead cables. If not maintained promptly due to thermal expansion and contraction, they can easily age, impacting the cable's proper function.

[0004] Therefore, protective measures should be strengthened for cable joints to avoid problems such as aging and breakage caused by thermal expansion and contraction. Although thermal expansion and contraction are an unavoidable natural phenomenon, preventive measures can be taken to reduce the impact on overhead cables. During the design and use process, attention should be paid to selecting appropriate materials and adopting measures such as adjustable brackets. At the same time, maintenance and protection work should be strengthened to ensure the safe operation of overhead cables.

[0005] Traditional cable connector installation methods mostly rely on manual operation, which is not only inefficient but also easily affected by environmental factors such as thermal expansion and contraction, leading to problems such as aging and breakage of cable connectors due to thermal expansion and contraction. Therefore, inventing an installation device that can resist thermal expansion and contraction of cable connectors is an urgent problem to be solved. Summary of the Invention

[0006] In order to solve the above technical problems, the present application provides a power tower that is convenient for installing cables.

[0007] The present application provides a power tower that is convenient for installing cables and adopts the following technical solutions: The utility model discloses an electric power tower which is convenient for installing cables, comprising a tower support, to which a mounting device is detachably connected; the mounting device comprises a fixing frame, on which a positioning mechanism is provided; the positioning mechanism comprises a mounting seat which is slidably connected to the fixing frame, a clamping plate is provided on the mounting seat, an arc-shaped slot is provided on the clamping plate, a cover plate is provided on the top of the clamping plate, the same slot is provided on the bottom of the cover plate, the cover plate is buckled on the clamping plate, the two slots are used for cable plugging, a plurality of mounting holes are correspondingly provided on the clamping plate and the cover plate, and bolts are sequentially passed through the mounting holes on the cover plate and the clamping plate and then threadedly connected with nuts; a locking assembly is provided between the cover plate and the clamping plate, and the locking assembly is used to lock the cover plate and the connecting plate.

[0008] By adopting the above technical solution, when the user uses and installs the cable, the cable connector is connected and fixed by the positioning sleeve, and then the fixing sleeve is placed in the cable slot, and the cover plate is buckled on the top of the clamping plate. The bolts pass through the mounting holes on the cover plate and the clamping plate in turn and are threadedly connected with nuts, so that the cover plate and the clamping plate can be connected and fixed. The locking assembly locks the clamping plate and the cover plate for the second time, thereby reducing the thermal expansion and contraction of the cable and separating the cover plate and the clamping plate.

[0009] Optionally, the locking assembly includes positioning grooves opposite to each other on the cover plate and the clamping plate, and a plurality of wedge-shaped grooves are symmetrically provided on the cover plate and the clamping plate. The wedge-shaped grooves are connected to the positioning grooves, and a positioning rod is inserted into the positioning groove. Wedge blocks are fixedly connected on both sides of the positioning rod symmetrically, and the wedge blocks are used to be inserted into the wedge grooves.

[0010] By adopting the above technical solution, when the user uses and installs the cable connector, the cable connectors are abutted together, and then the positioning sleeve is put on, and the positioning rod is slid from the side of the cover plate and the clamping plate into the positioning groove, so that the wedge blocks on both sides of the positioning rod are clamped in the wedge grooves of the cover plate and the clamping plate. When the cable expands and contracts due to thermal expansion and contraction, the pressure of the cable on the clamping plate and the cover plate pushes the clamping plate and the cover plate to slide, and the inclined surfaces of the wedge groove and the wedge block abut against each other, making the cover plate and the clamping plate abut more firmly, thereby preventing the cable connector from being detached from the clamping slot of the clamping plate and the cover plate.

[0011] Optionally, two guide columns are fixedly connected to the fixed frame, a sliding cylinder is slidably connected to the guide column, multiple scraper rods are fixedly connected to both ends of the sliding cylinder, and an inclined surface is provided at the end of the scraper rod away from the sliding cylinder. The fixed frame is provided with an adjustment mechanism that drives the mounting seat to slide vertically according to the thermal expansion and contraction of the cable to tighten or relax the cable.

[0012] By adopting the above technical solution, when the user uses it, the inclined surface makes it easy for the scraper rod to be inserted into the side wall of the guide column, making it easy to pry the ice on the side wall of the guide column and to de-ice the side wall of the guide column. When the cable expands and sags due to heat in hot weather, the cable can be tensioned. When the cable contracts and is tensioned due to the low temperature in winter, the cable is driven to slide downward, releasing a certain amount of pressure on the cable and reducing cable damage.

[0013] Optionally, the adjustment mechanism includes a connecting rod fixedly connected to the sliding seat, a piston cylinder fixedly connected to the middle position of the fixed frame, buffer oil is provided in the piston cylinder, the buffer oil has the effect of thermal expansion and contraction, the connecting rod is fixedly connected to the piston shaft away from the end, the end of the piston shaft extends into the buffer cylinder and is fixedly connected to the piston plate.

[0014] By adopting the above technical solution, when the user uses it, when the cable expands due to heat and sags in the summer, the buffer oil in the piston cylinder expands due to heat, pushing the piston plate to slide upward, and the piston plate slides upward through the mounting seat, and then pulls the entire cable to slide upward, thereby tensioning the drooping cable; when the cable shrinks and is tensioned in the winter, the buffer oil in the piston cylinder shrinks in volume, and then drives the mounting seat to slide upward through the connecting rod, and then drives the cable to slide downward, reducing the pressure of the cable's own gravity, thereby reducing damage to the cable.

[0015] Optionally, a plurality of buffer cylinders are fixedly connected to the fixed frame, the axial direction of the buffer cylinder is parallel to the axial direction of the piston cylinder, a buffer cavity is provided at the bottom of the fixed frame, the buffer cavity is connected with the piston cylinder and the buffer cylinder, the buffer cylinder and the buffer cavity are filled with buffer oil with the same structure as the piston cylinder, and two guide surfaces are provided at the bottom of the buffer cavity, and the guide surfaces are inclined upward from the middle of the buffer cavity to both ends.

[0016] By adopting the above technical solution, when the user uses it, multiple buffer cylinders can increase the capacity of the buffer oil, thereby increasing the volume change of the buffer oil due to thermal expansion and contraction, ensuring that the volume change of the buffer oil can tighten or release the pressure on the cable, thereby achieving the adjustment of the thermal expansion and contraction of the cable. The inclined surface can facilitate the buffer oil to quickly enter the buffer cylinder. When the piston plate in the piston cylinder is subjected to increased or decreased pressure, the piston plate in the piston cylinder applies pressure to the buffer oil, and the guide surface can facilitate the even distribution of the buffer oil to each buffer cylinder.

[0017] Optionally, the buffer oil is kerosene.

[0018] By adopting the above technical solution, users can use kerosene because of its low specific heat capacity. Specific heat capacity is a measure of the temperature change when a substance absorbs or releases heat. The smaller the specific heat capacity, the faster the temperature change. Kerosene has a low specific heat capacity, so when absorbing the same amount of heat, its temperature rises faster and its volume change is more pronounced. Therefore, kerosene's thermal expansion and contraction are the most pronounced among common liquids. Under the same conditions, kerosene heats up the fastest after absorbing the same amount of heat, and is therefore most significantly affected by thermal expansion and contraction. This ensures that the kerosene's volume change can tension or release pressure on the cable, thereby adjusting the cable's thermal expansion and contraction.

[0019] Optionally, a buffer spring is provided on the top of the inner wall of the buffer cylinder, the buffer spring is vertically arranged, and a sealing plate is fixedly connected to the bottom of the buffer spring.

[0020] By adopting the above technical solution, when the user uses it, when the cable swings under the action of wind, it drives the piston plate to slide, and the sealing plate squeezes the buffer spring. The tension of the buffer spring gives the buffer plate a certain amount of movement space, which plays a role in buffering and resetting the piston plate, and at the same time slows down the swing of the cable under the action of wind.

[0021] Optionally, the top of the fixing frame is fixedly connected with a mounting ring, the bottom of the tower support is fixedly connected with an insulator string, the bottom of the insulator string is fixedly connected with a connecting ring, and the bolt passes through the mounting ring and the connecting ring and is threadedly connected with a nut.

[0022] By adopting the above technical solution, when the user uses it, the bolt passes through the installation ring and the connecting ring and is threadedly connected with a nut, thereby connecting and fixing the fixing frame to the tower support. The main function of the insulator string is to insulate the conductor from the tower and the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] The present application discloses a power tower that is convenient for installing cables. Figure 1 , including an iron tower support 1, on which a mounting device 2 is provided. The mounting device 2 is used to assemble and fix the joints of the cables and at the same time bear the weight of the cables.

[0027] Reference Figure 2 and Figure 3The mounting device 2 includes a fixing frame 21, the sidewall of which is slidably connected to a positioning mechanism 22. The top of the fixing frame 21 is fixedly connected to a mounting ring 211, the bottom of the tower support 1 is fixedly connected to an insulator string 11, and the bottom of the insulator string 11 is fixedly connected to a connecting ring 12. Bolts pass through the mounting ring 211 and the connecting ring 12 and are then threadedly connected to nuts, thereby connecting the fixing frame 21 to the tower support 1.

[0028] Two guide posts 212 are fixedly connected to the fixed frame 21, and the axial direction of the guide posts 212 is vertically arranged. The positioning mechanism 22 includes a sliding cylinder 213 that is slidably connected to the guide posts 212. Multiple scraper rods 214 are fixedly connected to both ends of the sliding cylinder 213. The scraper rods 214 are evenly distributed along the circumference of the sliding cylinder 213. The ends of the scraper rods 214 away from the sliding cylinder 213 are provided with inclined surfaces. The inclined surfaces facilitate the scraper rods 214 to be inserted into the side walls of the guide posts 212, so as to pry the ice on the side walls of the guide posts 212 and de-ice the side walls of the guide posts 212.

[0029] Reference Figure 3 and Figure 4 The positioning mechanism 22 includes a mounting base 221 commonly connected to the two sliding cylinders 213, a clamping plate 222 is provided on the mounting base 221, and an arc-shaped card slot 223 is provided on the clamping plate 222, and the card slot 223 is used to clamp the cable connector, and a cover plate 224 is provided on the top of the clamping plate 222, and the same card slot 223 is provided on the bottom of the cover plate 224, and the cover plate 224 is buckled on the clamping plate 222. The two card slots 223 are used for cable plugging, and a plurality of mounting holes 225 are correspondingly provided on the clamping plate 222 and the cover plate 224. The bolts pass through the mounting holes 225 on the cover plate 224 and the clamping plate 222 in turn and are threadedly connected with nuts, so that the cover plate 224 and the clamping plate 222 can be connected and fixed.

[0030] A positioning groove 226 is provided on the opposite side of the cover plate 224 and the clamping plate 222. A plurality of wedge-shaped grooves 227 are symmetrically provided on the cover plate 224 and the clamping plate 222. The wedge-shaped groove 227 is connected to the positioning groove 226. The wedge-shaped groove 227 is located at the end of the cover plate 224 and the clamping plate 222 away from the mounting seat 221. A positioning rod 228 is inserted into the positioning groove 226. Wedge blocks 229 are fixedly connected to the symmetrical sides of the positioning rod 228. The wedge blocks 229 are used to be inserted into the wedge groove 227. When installing the cable connector, the cable connectors are abutted together, and then the positioning sleeve is put on. The sides of the cover plate 224 and the clamping plate 222 slide the positioning rod 228 into the positioning groove 226, so that the wedge blocks 229 on both sides of the positioning rod 228 are clamped in the wedge grooves 227 of the cover plate 224 and the clamping plate 222. When the cable expands and contracts due to thermal expansion and contraction, the pressure of the cable on the clamping plate 222 and the cover plate 224 pushes the clamping plate 222 and the cover plate 224 to slide. The inclined surfaces of the wedge groove 227 and the wedge block 229 abut against each other, making the cover plate 224 and the clamping plate 222 more firmly abutted, thereby preventing the cable connector from detaching from the clamping plate 222 and the cover plate 224.

[0031] The two ends of the clamping plate 222 are fixedly connected with a guide cylinder 23, which is used for the cable to pass through. The outer diameter of the guide cylinder 23 gradually decreases from the end of the clamping plate 222 to the end away from the clamping plate 222, so that the guide cylinder 23 can serve as a guide for the ice-cleaning robot, making it convenient for the ice-cleaning robot to slide from the guide cylinder 23 through the top of the clamping plate 222 and the cover plate 224, so that the robot can clear ice from the cable.

[0032] Reference Figure 2 and Figure 5 The fixing frame 21 is provided with an adjustment mechanism 3. This mechanism is used to adjust the cable according to its thermal expansion and contraction. When the cable expands and sags due to heat in hot weather, the mechanism can tighten the cable. When the cable contracts and is tightened in winter due to low temperatures, the mechanism drives the cable downward, releasing a certain amount of pressure on the cable and reducing cable damage. The adjustment mechanism 3 includes a connecting rod 31 fixedly connected to the sliding seat. A piston cylinder 32 is fixedly connected to the middle position of the fixing frame 21. The piston cylinder 32 contains buffer oil, which has the effect of thermal expansion and contraction. A piston shaft 33 is fixedly connected to the distal end of the connecting rod 31. The end of the piston shaft 33 extends into the buffer cylinder 34 and is fixedly connected to the piston plate 331. When the cable expands due to heat in summer and sags, the buffer oil in the piston cylinder 32 expands due to heat, pushing the piston plate 331 to slide upward, and the piston plate 331 slides upward through the mounting seat 221, thereby pulling the entire cable to slide upward, thereby tensioning the drooping cable; when the cable shrinks and is tensioned in winter, the buffer oil in the piston cylinder 32 is reduced in volume, and then drives the mounting seat 221 to slide upward through the connecting rod 31, and then drives the cable to slide downward, reducing the pressure of the cable's own gravity, thereby reducing damage to the cable.

[0033] The fixing frame 21 is fixedly connected to a plurality of buffer cylinders 34, which are symmetrically distributed on both sides of the piston cylinder 32. The axial direction of the buffer cylinder 34 is parallel to the axial direction of the piston cylinder 32. The buffer cylinder 34 is hollow. A buffer cavity 35 is provided at the bottom of the fixing frame 21. The buffer cavity 35 is communicated with the piston cylinder 32 and the buffer cylinder 34. The buffer cylinder 34 and the buffer cavity 35 are filled with buffer oil with the same structure as the piston cylinder 32. The bottom of the buffer cavity 35 is provided with two guide surfaces 351. The guide surfaces 351 extend from the middle of the buffer cavity 35 to both ends. Upward inclination; multiple buffer cylinders 34 can increase the capacity of the buffer oil, thereby increasing the volume change of the buffer oil due to thermal expansion and contraction, ensuring that the volume change of the buffer oil can tighten or release the pressure on the cable, thereby achieving adjustment of the thermal expansion and contraction of the cable; the inclined surface can facilitate the buffer oil to quickly enter the buffer cylinder 34, and when the piston plate 331 in the piston cylinder 32 is subjected to pressure increase or decrease, the piston plate 331 in the piston cylinder 32 applies pressure to the buffer oil, and the guide surface 351 can facilitate the buffer oil to be evenly distributed in each buffer cylinder 34.

[0034] The buffer oil is kerosene because it has a relatively low specific heat capacity. Specific heat capacity is a measure of the temperature change when a substance absorbs or releases heat. The smaller the specific heat capacity, the faster the temperature change. Kerosene has a relatively low specific heat capacity, so when absorbing the same amount of heat, its temperature rises faster and its volume change is more pronounced. Therefore, kerosene's thermal expansion and contraction are the most pronounced among common liquids. Under the same conditions, kerosene heats up the fastest after absorbing the same amount of heat, and is therefore most significantly affected by thermal expansion and contraction. This ensures that the kerosene's volume changes can tension or release pressure on the cable, thereby regulating the cable's thermal expansion and contraction.

[0035] A buffer spring 36 is provided at the top of the inner wall of the buffer cylinder 34. The buffer spring 36 is arranged vertically. The bottom of the buffer spring 36 is fixedly connected to a sealing plate 37. When the cable swings under the action of wind, it drives the piston plate 331 to slide, and the sealing plate 37 squeezes the buffer spring 36. The tension of the buffer spring 36 gives the buffer plate a certain amount of movement space, which plays a role in buffering and resetting the piston plate 331, and at the same time slows down the swing of the cable under the action of wind.

[0036] Among them, reinforcing rods 215 are provided at both ends of the fixing frame 21, and the end of the reinforcing rod 215 away from the fixing frame 21 is fixedly connected to a support tube 216. The support tube 216 is used for the industrial cable to pass through. The support tube 216 and the reinforcing rod 215 cooperate to support and bear the weight of the cable, and can also reduce the swing of the cable under the action of strong wind.

[0037] The implementation principle of an electric power tower that is convenient for installing cables in the embodiment of the present application is as follows: when installing the cable, remove the bolts and nuts on the cover plate 224 and the clamping plate 222, then remove the cover plate 224, abut the cable connector together, and then put on the positioning sleeve, slide the positioning rod 228 into the positioning groove 226 from the side of the cover plate 224 and the clamping plate 222, so that the wedge blocks 229 on both sides of the positioning rod 228 are clamped in the wedge grooves 227 of the cover plate 224 and the clamping plate 222. When the cable expands and contracts due to heat and cold, the pressure of the cable on the clamping plate 222 and the cover plate 224 pushes the clamping plate 222 and the cover plate 224 to slide, and the cover plate 224 and the clamping plate 222 are more firmly abutted through the abutment of the wedge groove 227 and the inclined surface of the wedge block 229, thereby preventing the cable connector from detaching from the clamping groove 223 of the clamping plate 222 and the cover plate 224.

[0038] At the same time, when the cable sags due to heat expansion in summer, the kerosene in the piston cylinder 32 expands due to heat, pushing the piston plate 331 to slide upward, and the piston plate 331 slides upward through the mounting seat 221, thereby pulling the entire cable to slide upward, thereby tensioning the drooping cable; when the cable shrinks and is tensioned in winter, the volume of the kerosene in the piston cylinder 32 decreases, and then drives the mounting seat 221 to slide upward through the connecting rod 31, and then drives the cable to slide downward, reducing the pressure of the cable's own gravity, thereby reducing damage to the cable and extending the service life of the cable.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
