Description
Technical Field
[0001] The invention relates to a wind-resistant transmission tower, belonging to the technical field of transmission towers. Background Art
[0002] The transmission tower is the supporting point of the overhead line. If one circuit is erected on the transmission tower, it is a single-circuit transmission tower, and if two circuits are erected on the transmission tower, it is a double-circuit transmission tower. A single circuit refers to a circuit with one power supply for one load; a double circuit refers to a circuit with two power supplies for one load. Generally, enterprises with high requirements for power supply reliability or important regional substations use double-circuit power supply, which can protect one power supply from power outage for some reason, while the other power supply can continue to supply power. However, for general small and medium-sized users who do not have high requirements for power supply reliability, single power supply is often used.
[0003] During the power transmission process, in order to ensure that it does not affect the personnel and buildings on the ground, the tower poles of the transmission towers will be built longer, making the transmission towers taller. Due to the lack of obstacles at high altitudes, very high transmission towers are easily affected by stronger winds than those on the ground. In addition, the tower poles are higher, which will cause greater shaking when affected by wind. Long-term shaking can easily lead to fatigue of the transmission lines and tower poles. If they are not inspected and repaired in time, they will cause breakage, affecting power transmission.
[0004] In view of the above technical problems, after searching, a Chinese patent with publication number CN213391432U discloses a wind-resistant transmission tower, the technical key points of which are: including a fixed seat, a tower pole, a wiring board, a lamp, and a wind-resistant block. The fixed seat is embedded and connected to the tower pole, the wiring board is bolted to the tower pole, the lamp is embedded on the tower pole, and the wind-resistant block is installed on the tower pole; the wind-resistant block includes a protective shell, a limit groove, a ball, a connecting shaft, a ball sleeve, a gravity ball, a connecting block, a bearing, a damper, and a rolling plate. The limit groove and the protective shell are integrated into one, and the ball is installed in the limit groove.
[0005] In the above scheme, the wind damper is designed to compensate and absorb the swaying of the tower. However, in the case of strong wind, the tower of the transmission tower will still sway significantly, affecting the safety of the transmission line.
[0006] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0014] The present invention is further configured as follows: the telescopic rods are all arranged at an angle, the first transmission shaft and the second transmission shaft both include a first shaft body and a second shaft body meshed by a bevel gear pair, the second shaft body is arranged vertically, and the first shaft body is arranged at an angle relative to the second shaft body.
[0015] The present invention is further configured as follows: the second shaft body in the second transmission shaft includes a first connecting section, a second connecting section, and a one-way transmission member arranged between the first connecting section and the second connecting section; The one-way transmission member includes a connecting hole opened at the bottom end surface of the first connecting section, a connecting column slidably inserted in the connecting hole and connected to the inner wall of the connecting hole by a spline, a connecting spring arranged in the connecting hole and abutting against the top end of the connecting column, a first end face ratchet fixedly connected to the bottom end of the connecting column, and a second end face ratchet fixedly connected to the top end surface of the second connecting section and matching the first end face ratchet.
[0016] The beneficial effects of the present invention are: By setting a base and a plurality of groups of supporting components to cooperate, in windy weather conditions, the impeller in a group of supporting components facing the wind rotates under the influence of wind force, and the impeller drives the driving shaft to rotate. Since the driving shaft and the input shaft of the air pump are in transmission connection, the air pump starts following the rotation of the impeller, and presses the external air into the piston cavity, so that the air pressure in the piston cavity increases, and at the same time pushes the piston block and the piston rod to apply force to the tower body from the inside of the tower body, and the horizontal force of the tower body offsets the wind force, thereby reducing the deflection of the tower body due to the influence of wind force, and improving the safety of the transmission tower in windy weather; By setting up an energy storage mechanism, when the wind force is relatively small, the driving shaft drives the second transmission shaft to rotate through the bevel gear pair. Since a centrifugal clutch is provided between the second transmission shaft and the second transmission gear, the second transmission gear meshing with the first transmission gear does not drive the air pump to start at this time, but drives the outer gear ring to rotate through the energy storage gear, so that the outer gear ring drives the torsion spring to rotate, thereby converting wind energy into mechanical energy for storage. When the wind force is relatively large, the speed of the second transmission shaft increases, so that the centrifugal clutch connected to the second transmission shaft forms a transmission relationship with the second transmission gear under the action of centrifugal force, so that the second transmission shaft can directly drive the first transmission shaft. A transmission shaft rotates, and when the first transmission shaft rotates, the driven gear is driven to rotate through the spline. When the driven gear rotates, the dovetail block slidably connected in the dovetail groove is thrown toward the outer edge of the driven gear. Under the connection of the driving rod, the driven gear moves downward, and the turntable is pushed to move the inner gear ring downward as a whole. At this time, the driven gears in the other groups of supporting components are separated from the inner gear ring, and at the same time, the limit groove on the outer wall of the inner gear ring is separated from the limit block. The torsion spring drives the force application shaft to rotate, thereby further boosting the driven gear through the inner gear ring, so that the first transmission shaft quickly obtains a high speed, so that the telescopic rod increases the supporting force of the tower rod body. By arranging a one-way transmission component on the second shaft body of the second transmission shaft, when the strong wind stops, the impeller can be blown by the reverse airflow to drive the second transmission shaft to reverse, thereby unlocking the centrifugal clutch and causing the second transmission shaft and the second transmission gear to lose the transmission relationship, so that the second transmission shaft can continue to store energy in the torsion spring.

[0038] In order to make the internal gear ring 42 rotate so that only the passive gear 44 in the support assembly 3 on the side of the windward airflow rotates, a sliding hole 52 is opened on the bottom surface of the installation cavity 15, and the force shaft 31 is slidably connected in the sliding hole 52 along the vertical direction.

[0041] The implementation principle of the present invention is: When the wind force is relatively small, the driving shaft 12 drives the second transmission shaft 17 to rotate through the bevel gear pair 20. Since a centrifugal clutch 23 is provided between the second transmission shaft 17 and the second transmission gear 22, the second transmission gear 22 meshing with the first transmission gear 21 does not drive the air pump 10 to start at this time, but drives the outer gear ring 32 to rotate through the energy storage gear, so that the outer gear ring 32 drives the torsion spring 33 to rotate, and the wind energy is converted into mechanical energy for storage. When the wind force is relatively large, the speed of the second transmission shaft 17 increases, so that the centrifugal clutch 23 connected to the second transmission shaft 17 forms a transmission relationship with the second transmission gear 22 under the action of centrifugal force, so that the second transmission shaft 17 can directly drive the first transmission shaft 16 to rotate, and when the first transmission shaft 16 rotates, it drives the passive gear 44 to rotate through the spline, and when the passive gear 44 rotates, it makes the sliding connection to the dovetail groove The dovetail block 50 in 49 is thrown toward the outer edge of the passive gear 44, and under the connection of the driving rod 51, the passive gear 44 moves downward, and pushes the turntable 41 to move the inner gear ring 42 downward as a whole. The passive gears 44 in the other groups of support assemblies 3 are disengaged from the inner gear ring 42, and at the same time, the limiting groove 55 on the outer wall of the inner gear ring 42 is disengaged from the limiting block 56, and the torsion spring 33 drives the force application shaft 31 to rotate, thereby further pressurizing the passive gear 44 through the inner gear ring 42, and the air pump 10 is started accordingly, and the external air is pressed into the piston chamber 7, so that the air pressure in the piston chamber 7 is increased, and at the same time, the piston block 8 and the piston rod 9 are pushed to apply force to the tower body 1 from the inside of the tower body 1, and the component force of the tower body 1 in the horizontal direction offsets the wind force, thereby reducing the deflection of the tower body 1 due to the influence of wind force, and improving the safety of the transmission tower in windy weather.
