Description

Technical Field

[0001] The present application relates to the technical field of power transmission, and in particular to a power transmission rack. Background Art

[0002] In the field of power transmission, the design and function of the transmission rack as a tower structure supporting transmission cables are crucial to the stability and safety of the power system. The main function of the transmission rack is to raise the high-voltage transmission line from the ground to reduce the interference of the transmission cable on traffic, buildings and other facilities, keep the transmission cable at a certain height and tension, and ensure that electricity can be transmitted safely and efficiently to reduce the risk of electric shock.

[0003] Normally, a transmission rack clamps and fixes the transmission cable by means of a wire clamp so that the transmission cable between two adjacent transmission racks has a certain tension force, that is, the portion of the transmission cable located between two adjacent transmission racks and clamped by the wire clamp is the tension section; accordingly, a slack section is left at the transmission rack for the transmission cable to leave space for the connection between the transmission cable and the substation or distribution network; in actual applications, the slack section of the transmission cable can allow the transmission cable to have a certain expansion and contraction space when the temperature changes, thereby avoiding excessive tension or damage to the transmission cable due to thermal expansion and contraction.

[0004] In the prior art, the position of the cable clamp on the transmission rack is relatively fixed, so that the end of the tensioning section of the transmission cable is fixed. However, during long-term use, the tension of the tensioning section of the transmission cable changes due to the influence of temperature, wind force and direction, and the load of the transmission cable itself, thereby affecting the stability and service life of the transmission cable. Summary of the invention

[0005] The purpose of the present application is to provide a power transmission rack, aiming to solve the problem that the tension of the tensioning section of the transmission cable changes and thus affects the stability and service life of the transmission cable.

[0006] In order to solve the above technical problems, the present application provides a power transmission rack, including a base, a rotating base vertically connected to the base, and a wiring base horizontally slidably connected to the rotating base, a reset turntable is provided at the connection between the rotating base and the base, the wiring base is provided with a plurality of wire clamps for connecting power transmission cables, the rotating base is installed with an electric servo cylinder for pushing the wire clamps on the wiring base to tighten the power transmission cables, the electric servo cylinder is provided with a barometer for measuring the air pressure in the electric servo cylinder, and the base is provided with a controller communicatively connected to the electric servo cylinder and the barometer.

[0007] As can be seen from the above, the present application provides a power transmission rack that can eliminate the influence of temperature, wind force and direction, and the load of the transmission cable itself, so that the stability and service life of the transmission cable are guaranteed.

[0008] As an improvement of the above-mentioned scheme, the terminal block is horizontally rotatably connected to a plurality of guide wheels which are arranged one-to-one on the outside of the wire clamp. The guide wheel is provided with a horn through hole whose inner diameter gradually increases from the inside to the outside. The inner diameter of the inner end of the horn through hole matches the outer diameter of the transmission cable clamped by the wire clamp to adapt to the influence of different wind directions on the tensioning section of the transmission cable.

[0009] As an improvement on the above scheme, the rotating seat is provided with two L-shaped guide rails arranged symmetrically on the left and right, and the two lower corners of the wiring seat are slidably connected to the two L-shaped guide rails in a one-to-one correspondence; the two lower corners of the wiring seat are provided with two T-shaped sliders arranged perpendicular to each other and spaced apart from each other, and the L-shaped guide rail is provided with two T-shaped slide grooves slidably connected to the T-shaped sliders in a one-to-one correspondence, thereby realizing a horizontal sliding connection between the wiring seat and the rotating seat.

[0010] As an improvement of the above scheme, the lower two corners of the terminal block are provided with a accommodating cavity, the accommodating cavity is filled with lubricating oil, and the T-shaped slider is equipped with a plurality of balls connected with the accommodating cavity and in contact with the T-shaped slide groove, which lubricates the contact between the T-shaped slide groove and the T-shaped slider.

[0011] As an improvement of the above scheme, a connecting plate is provided between the two T-shaped sliders at the two lower corners of the terminal block, and the output end of the electric servo cylinder is provided with two linkage rods which are connected to the two connecting plates one by one, thereby realizing the connection between the output end of the electric servo cylinder and the two connecting plates.

[0012] As an improvement of the above-mentioned scheme, the reset turntable includes a chassis installed on a base, an eccentric wheel rotating synchronously with a rotating seat, a rocker arm hinged to the chassis at one end, a roller hinged to the middle part of the rocker arm, and a tension spring whose two ends are respectively connected to the other end of the rocker arm and the chassis to press the middle part of the rocker arm toward the eccentric wheel. The center of the eccentric wheel is eccentrically arranged with respect to the rotation axis of the rotating seat to realize the reset function of the reset turntable.

[0013] As an improvement of the above scheme, the reset turntable also includes two limit plates which are correspondingly arranged on the upper and lower sides of the eccentric wheel and rotate synchronously with the eccentric wheel. The outer contour of the limit plate is offset outward relative to the outer contour of the eccentric wheel, which can limit the upper and lower positions of the roller.

[0014] As an improvement of the above-mentioned solution, the power transmission rack of the present application also includes an angle adjustment mechanism, which includes a first bevel gear that rotates synchronously with the rotating seat, a second bevel gear that meshes with the first bevel gear, and a servo motor installed on the base for driving the second bevel gear to rotate.

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0036] It should be noted that changes in external temperature or / and the heating of the load of the transmission cable itself will cause the temperature of the transmission cable to change, and the temperature change will cause the thermal expansion and contraction of the transmission cable, resulting in changes in the length of the transmission cable, thereby affecting the tension; when the temperature decreases, the transmission cable material will shrink, which may lead to an increase in the tension of the transmission cable, while the opposite is true when the temperature increases; this change may affect the stability and mechanical properties of power transmission, and long-term temperature changes may cause fatigue and damage to the transmission cable. Changes in wind force and direction will generate additional loads on the transmission cable, resulting in changes in tension; strong winds may cause the transmission cable to vibrate and swing more, increase the tension of the transmission cable, and changes in wind direction may change the direction of force on the transmission cable, affecting the stability of the transmission cable. Changes in wind force and direction will generate additional loads on the transmission cable, resulting in changes in tension. Strong winds may increase the tension of the transmission cable, and changes in wind direction may change the direction of force on the transmission cable, affecting the stability of the transmission cable. Unstable tension may cause the vibration of the transmission cable to intensify, accelerate the wear of the transmission cable, and reduce the service life of the transmission cable. Therefore, in order to ensure the long-term stable operation of the transmission cable, it is necessary to automatically adjust the tension of the transmission cable to adapt to environmental changes and load conditions and reduce the adverse effects of tension changes on the stability and service life of the transmission cable.

[0037] like Figures 1 to 3As shown, a power transmission rack in an embodiment of the present application includes a base 100, a rotating base 200 vertically connected to the base 100, and a wiring base 300 horizontally slidably connected to the rotating base 200. In fact, the base 100 plays a role in connecting the foundation at a preset position. The technical solution of the present application is mainly to improve the connection relationship between the base 100, the rotating base 200 and the wiring base 300. Figure 1 The structure of the base 100 connecting to the foundation is omitted, and the structure and principle of the base 100 connecting to the foundation are not described one by one; the rotating seat 200 and the base 100 can be rotatably connected by means of bearings, rotating rods and rotating through holes, and the rotation axis of the rotating seat 200 is perpendicular to the horizontal plane when the rotating seat 200 rotates relative to the base 100; the wiring seat 300 and the rotating seat 200 can be slidably connected by means of sliders and rails, one-way guide rail components, and the sliding direction of the wiring seat 300 is parallel to the horizontal plane when the wiring seat 300 slides relative to the rotating seat 200; in addition, the wiring seat 300 can also drive the rotating seat 200 to rotate relative to the base 100 to change the angle of the wiring seat 300 relative to the base 100.

[0038] A reset turntable 400 is provided at the connection between the rotating seat 200 and the base 100. When an external force acts on the rotating seat 200 to cause the rotating seat 200 to rotate relative to the base 100, the reset turntable 400 generates a corresponding reaction force to offset the force of the rotating seat 200, so that the rotating seat 200 generates a certain deflection angle relative to the base 100; as the external force is removed, the reset turntable 400 pushes the rotating seat 200 back to its original position relative to the base 100.

[0039] The wiring seat 300 is provided with a plurality of wire clamps 310 for connecting power transmission cables, and is used to clamp and fix the power transmission cables, so that the power cables between two adjacent power transmission racks form a tensioning section. The attached figure shows that the wiring seat 300 is provided with two wire clamps 310. In actual application, the number of wire clamps 310 can be adjusted according to the number of cables to be clamped, so that the plurality of wire clamps 310 clamp the plurality of cables in a one-to-one correspondence.

[0040] The rotating seat 200 is equipped with an electric servo cylinder 500 for pushing the wire clamp 310 on the wiring seat 300 to tighten the power transmission cable. The electric servo cylinder 500 is provided with a barometer 510 for measuring the air pressure in the electric servo cylinder 500. The base 100 is provided with a controller (not shown in the drawings) that is in communication with the electric servo cylinder 500 and the barometer 510. Figure 3As shown, if the tensioning section of the transmission cable is arranged at the rear side of the wire clamp 310, the electric servo cylinder 500 is arranged at the rear of the wire clamp 310, and the force of the output end of the electric servo cylinder 500 acts on the terminal block 300 from the back to the front to resist the tension acting on the wire clamp 310 and transmitted to the terminal block 300 when the transmission cable is tensioned; the electric servo cylinder 500 is provided with a bidirectional air pump, which can change the air volume in the cylinder barrel of the electric servo cylinder 500, that is, change the position of the output end of the electric servo cylinder 500, so as to change the relative position of the terminal block 300 and the rotating base 200; the controller can be a control device such as a programmable logic control device, a programmable automation control device, an industrial computer, an industrial computer, a distributed control system, etc., which can read the barometer 51 0 measures the air pressure value of the air in the cylinder of the electric servo cylinder 500, thereby calculating the thrust of the output end of the electric servo cylinder 500 acting on the terminal block 300, so as to obtain the tension of the tensioning section of the transmission cable acting on the wire clamp 310; the operator sets a preset air pressure value for the air in the cylinder, and when the barometer 510 measures that the air pressure value of the air in the cylinder is less than the preset air pressure value, the controller controls the two-way pump of the electric servo cylinder 500 to introduce air into the cylinder, so that the other pressure in the cylinder of the electric servo cylinder 500 reaches the preset air pressure value; conversely, when the barometer 510 measures that the air pressure value of the air in the cylinder is greater than the preset air pressure value, the controller controls the two-way pump of the electric servo cylinder 500 to extract air from the cylinder, so that the other pressure in the cylinder of the electric servo cylinder 500 reaches the preset air pressure value.

[0041] Therefore, when the temperature of the transmission cable changes due to the external temperature and / or the load of the transmission cable itself, causing the tensioning section of the transmission cable to expand and contract, the front and rear positions of the wire clamp 310 are changed under the action of the electric servo cylinder 500, the barometer 510 and the controller, and the force applied by the wire clamp 310 to the transmission cable is kept stable, so as to ensure the stability of the tensioning force of the tensioning section of the transmission cable.

[0042] Similarly, when the wind force acting on the transmission cable changes, causing the tensioning section of the transmission cable to change, the front and rear positions of the wire clamp 310 can be changed and the force of the wire clamp 310 acting on the transmission cable can be kept stable under the action of the electric servo cylinder 500, the barometer 510 and the controller, so as to ensure the stability of the tensioning force of the tensioning section of the transmission cable.

[0043] It is worth mentioning that when the wind direction changes, the direction of the pulling force exerted by the tension section of the transmission cable on the wire clamp 310 will change. At this time, since the rotating seat 200 is rotatably connected to the base 100, the wire clamp 310 drives the terminal seat 300 to connect to the rotating seat 200 and deflect relative to the base 100, and under the action of the reset turntable 400, the deflection torque of the tension section of the transmission cable on the wire clamp 310 is offset to improve the stability of the tension section of the transmission cable, thereby reducing the vibration of the tension section of the transmission cable caused by the change of wind direction.

[0044] The power transmission rack provided in the present application can detect the data changes detected by the barometer 510, thereby adaptively changing the front and rear positions of the wire clamp 310 under the action of the electric servo cylinder 500, the barometer 510 and the controller, and ensuring that the force applied by the wire clamp 310 on the transmission cable is stable, so as to ensure the stability of the tensioning force of the tensioning section of the transmission cable, and improve the stability of the tension section of the transmission cable under the action of the reset turntable 400, reduce the vibration of the tension section of the transmission cable caused by changes in wind direction, and eliminate the influence of temperature, wind force and direction and the load of the transmission cable itself, so that the stability and service life of the transmission cable are guaranteed.

[0045] In a preferred embodiment, the wiring seat 300 is preferably horizontally rotatably connected to a plurality of guide wheels 320 arranged one by one on the outside of the wire clamp 310, and the guide wheels 320 are provided with a horn through hole 321 with an inner diameter gradually increasing from the inside to the outside, and the inner diameter of the inner end of the horn through hole 321 matches the outer diameter of the power transmission cable clamped by the wire clamp 310. That is, the rotation axis of the guide wheel 320 is parallel to the horizontal plane and points to the wiring seat 300, such as Figure 2 As shown, the guide wheels 320 are arranged one by one behind the wiring seat 300 and are arranged in the center. The inner diameter of the inner end of the horn through hole 321, that is, the inner diameter of the end of the horn through hole 321 facing the wiring seat 300, matches the outer diameter of the transmission cable, which can allow the transmission cable to pass through and make the transmission cable between the wire clamp 310 and the guide wheel 320 almost in a horizontal state. The inner diameter of the horn through hole 321 gradually increases from the inside to the outside, which can adapt to the swing of the tensioning section of the transmission cable within a range of 360 degrees, so as to adapt to the influence of different wind directions on the tensioning section of the transmission cable. Furthermore, the cross-sectional edge of the horn through hole 321 is in the shape of an arc line, which plays a guiding role in the tensioning of the transmission cable, so that the tensioning of the transmission cable can better act on the wire clamp 310.

[0046] In some embodiments, Figure 4As shown, the rotating seat 200 is preferably provided with two L-shaped guide rails 210 symmetrically arranged on the left and right, and the two lower corners of the wiring seat 300 are slidably connected with the two L-shaped guide rails 210 in a one-to-one correspondence; the two lower corners of the wiring seat 300 are each provided with two T-shaped sliders 330 arranged perpendicularly and spaced from each other, and the L-shaped guide rail 210 is provided with two T-shaped slide grooves 211 slidably connected with the T-shaped sliders 330 in a one-to-one correspondence. The wiring seat 300 is horizontally slidably connected with the rotating seat 200 through the cooperation of the T-shaped sliders 330 and the T-shaped slide grooves 211, and the two pairs of T-shaped sliders 330 on the left and right sides cooperate with the T-shaped slide grooves 211 to prevent the wiring seat 300 from being offset left and right relative to the rotating seat 200 due to the change of wind direction, and realize the function of the wiring seat 300 driving the rotating seat 200 to deflect synchronously relative to the base 100.

[0047] In a preferred embodiment, if Figures 6 to 8 As shown, the lower two corners of the wiring seat 300 are preferably provided with a receiving cavity 340, and the receiving cavity 340 is filled with lubricating oil. The T-shaped slider 330 is equipped with a plurality of balls 331 that are connected with the receiving cavity 340 and in contact with the T-shaped slide 211. In fact, the end of the ball 331 away from the receiving cavity 340 is in contact with the T-shaped slide 211, and the part of the ball 331 facing the receiving cavity 340 is in contact with the lubricating oil in the receiving cavity 340. When the wiring seat 300 slides relative to the rotating seat 200, the ball 331 rolls and applies the lubricating oil in the receiving cavity 340 to the T-shaped slide 211, which plays a lubricating role on the contact between the T-shaped slide 211 and the T-shaped slider 330. Furthermore, the end of the ball 331 away from the receiving cavity 340 is coplanar with the side of the T-shaped slider 330 away from the receiving cavity 340, ensuring that the ball 331 can contact the T-shaped slide 211 and achieve lubrication. It should be noted that the wiring seat may also be provided with an oil filling hole 360 ​​communicating with the accommodating cavity 340 , and the oil filling hole is threadedly connected with a vent plug 370 so as to add lubricating oil to the accommodating cavity 340 .

[0048] It should be noted that if Figure 5 As shown, the lower two corners of the wiring base 300 are preferably provided with a connecting plate 350 between the two T-shaped sliders 330, and the output end of the electric servo cylinder 500 is provided with two linkage rods 520 connected to the two connecting plates 350 in a one-to-one correspondence. In fact, the output end of the electric servo cylinder 500 is provided with a linkage plate, and the two linkage rods 520 are arranged on the linkage plate at intervals, and the front part can be welded or threaded with the connecting plate 350 to have two nuts respectively abutting against the front and rear sides of the connecting plate 350, so as to realize the connection between the output end of the electric servo cylinder 500 and the two connecting plates 350, so that the electric servo cylinder 500 drives the wiring base 300 to move by pushing the connecting plate 350 to move.

[0049] It is worth mentioning that Fig. 9 As shown, the reset turntable 400 preferably includes a chassis 410 installed on the base 100, an eccentric wheel 420 that rotates synchronously with the rotating seat 200, a rocker arm 430 hinged to the chassis 410 at one end, a roller 440 hinged to the middle part of the rocker arm 430, and a tension spring 450 whose two ends are respectively connected to the other end of the rocker arm 430 and the chassis 410 to press the middle part of the rocker arm 430 toward the eccentric wheel 420. The center of the eccentric wheel 420 is eccentrically arranged with respect to the rotation axis of the rotating seat 200. In fact, the outer contour of the eccentric wheel 420 is circular. In the initial state, the roller 440 is pressed toward the outer side of the eccentric wheel 420, which is away from the rotation axis of the eccentric wheel 420, under the action of the swing rod 430 and the pull cross. When an external force acts on the rotating seat 200 to cause the rotating seat 200 to deviate relative to the base 100, the tension spring 450 stretches to generate a restoring tension until the tension spring 450 acts on the eccentric wheel 420 through the torque of the swing rod 430 and the roller 440 and the force of the external force on the eccentric wheel 420. When the torque is parallel, the angle of the rotating seat 200 relative to the base 100 is fixed, and it has a reset function after the external force is removed; further, the tension spring 450 also has a tension in the initial state, that is, the torque of the external force acting on the eccentric wheel 420 must be greater than the torque of the tension spring 450 acting on the eccentric wheel 420 through the rocker arm 430 and the roller 440 to drive the rotating seat 200 to rotate relative to the base 100, which plays a role in maintaining the stability of the rotating seat 200 to a certain extent, thereby reducing the vibration of the tensioning section of the transmission cable.

[0050] Furthermore, the reset turntable 400 preferably further includes two limit plates 460 correspondingly arranged at the upper and lower sides of the eccentric wheel 420 and rotating synchronously with the eccentric wheel 420, and the outer contour of the limit plate 460 is arranged to be offset outward relative to the outer contour of the eccentric wheel 420. Fig. 9 The dotted line shown indicates the upper limit plate 460 . In actual operation, the roller 440 is located between the two limit plates 460 . The two limit plates 460 can limit the upper and lower positions of the roller 440 to ensure the effectiveness of resetting the turntable 400 .

[0051] like Figure 1 and Fig.10As shown, the power transmission rack of the present application also includes a preferred angle adjustment mechanism 600, the angle adjustment mechanism 600 includes a first bevel gear 610 that rotates synchronously with the rotating seat 200, a second bevel gear 620 that meshes with the first bevel gear 610, and a servo motor 630 installed on the base 100 for driving the second bevel gear 620 to rotate, and the servo motor 630 is connected to the controller. Since the base 100 is fixed on the foundation after installation, it is used for production, processing and construction. The installation angle of the base 100 is inevitably offset, and the angle connecting the rotating seat 200 and the wiring seat 300 is correspondingly offset, affecting the wiring angle of the transmission cable; therefore, through the cooperation of the first bevel gear 610, the second bevel gear 620 and the servo motor 630, the angle of the rotation relative to the base 100 can be adjusted, thereby compensating for the influence of the angle deviation of the base 100 on the wiring angle of the transmission cable.

[0052] It is worth mentioning that Figure 1 As shown, the base 100 is preferably provided with a wind direction and anemometer 700 that is communicatively connected to the controller. Since the force of the reset turntable 400 will cause a certain deviation in the offset of the rotating seat 200 relative to the base 100, it is impossible to better compensate for the deviation of the force on the transmission cable caused by the wind direction. The current wind direction to the location of the power output rack is detected by the wind direction and anemometer 700, and the angles of the rotating seat 200 and the wiring seat 300 are adjusted according to the tension of the transmission cable, so that the wind direction has less influence on the transmission cable, and the stability of the tension of the transmission cable is further improved.

[0053] In the embodiment of the present application, the rotation axis of the first bevel gear 610 is preferably perpendicular to the rotation axis of the second bevel gear 620, so that the servo motor 630 can be set on the outside of the base 100 to facilitate maintenance of the servo motor 630 outside the base 100 and to more easily adjust the communication connection between the servo motor 630 and the controller.

[0054] The above are only specific embodiments of the present application, and the present application is introduced in detail. The relevant descriptions are only used to help understand the core idea of ​​the present application, and do not limit the patent scope of the present application. At the same time, for those skilled in the art, based on the idea of ​​the present application, equivalent structures or equivalent process changes made by using the description and drawings of the present application, or directly or indirectly applied in other related technical fields, are all included in the patent protection scope of the present application.
