Description

Technical Field

[0001] The utility model relates to the technical field of power transmission towers, in particular to an anti-wind power transmission tower capable of measuring the wind force magnitude. Background Art

[0002] Power transmission towers are tower-shaped buildings used for power transmission. Their main function is to serve as support points for overhead lines to transmit electric power resources. The design and manufacture of power transmission towers follow certain standards and specifications to ensure that they can safely and stably support and transmit electric power. The structural characteristics of these tower-shaped buildings include the use of a space truss structure, which is mainly composed of single equal-angle steel or combined angle steel. The materials are usually Q235 (A3F) and Q345 (16Mn). The connection between members uses rough bolts, and the shear force of the bolts is used for connection. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual components such as tower feet are welded into a combined component by several steel plates, which is convenient for hot-dip galvanizing anti-corrosion, transportation and construction erection.

[0003] In order to improve the applicability and flexibility of power transmission towers, a power transmission tower with high-strength wind resistance has emerged (specifically refer to the patent number: 202020192782.4), including a tower body, a fixing member is installed on the tower body, and a supporting member is installed on the fixing member. The fixing member includes an upper rotating ring and a lower rotating ring. The upper rotating ring is located above the lower rotating ring, and the upper rotating ring and the lower rotating ring are coaxially arranged; the wind force acts on the guiding plate, and the guiding plate drives the fixing cylinder to rotate to the downwind direction of the tower body. When the wind speed is too high, the output end of the electric push rod pushes the sliding support rod, and the grounding plate at the bottom of the sliding support rod contacts the ground. Under the action of the wind force, the tower body tilts to the downwind direction. At this time, the fixing cylinder and the sliding support rod can play an auxiliary supporting role to enhance the wind resistance of the tower body, and can adjust the position of the supporting member according to the wind direction by itself, adapt to various wind directions, and expand or retract by itself according to the magnitude of the wind speed.

[0004] However, the existing power transmission towers lack direct detection of the wind speed magnitude during the anti-wind operation, so that during the monitoring process, corresponding countermeasures cannot be given in time (for example: when the wind speed exceeds a certain value, in order to ensure safety, the circuit breaker needs to be cut off in time to reduce the affected area), thus reducing the safety of subsequent use and the utilization rate. Content of the Utility Model

[0005] The purpose of the present utility model is to solve the problem that in the process of wind resistance operation of existing power transmission towers, the detection of the wind speed magnitude is lacking, so that during the monitoring process, corresponding countermeasures cannot be given in time (for example: when the wind speed exceeds a certain value, in order to ensure safety, the circuit breaker needs to be cut off in time to reduce the affected area), thus reducing the safety of subsequent use and the utilization rate.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] 1. Through the arranged protection component, the first wind measurement component, the second wind measurement component, the third wind measurement component and the tension contact rod, by using the arranged first torsion spring, second torsion spring and third torsion spring, the elastic potential energies of the first torsion spring, the second torsion spring and the third torsion spring decrease in sequence and just form three grades. When the wind comes, the first fan blade rotates under the influence of the wind force, and directly drives the first sleeve and the first convex ring to rotate along the first annular chute, so that the first torsion spring is deformed by force and directly generates a force on the tension contact rod, and then the corresponding tension value is obtained according to the corresponding tension measurement module, and thus the corresponding wind force value can be obtained. When the wind force reaches the second grade, it can directly act on the second fan blade, so that the second fan blade is forced to drive the second sleeve and the second convex ring to rotate, and the second convex ring is movably connected to the bottom end inside the protective cover along the second annular chute, and the second torsion spring is deformed by force and directly generates a force on the tension contact rod, and then the corresponding tension value is obtained according to the corresponding tension measurement module, and thus the corresponding wind force value can be obtained. When the wind force reaches the third grade, it will cause the third fan blade to be forced to drive the sleeve rod to rotate, and the third torsion spring is deformed by force and directly generates a force on the tension contact rod, and then the corresponding tension value is obtained according to the corresponding tension measurement module, and thus the corresponding wind force value can be obtained. Therefore, the wind force can be measured according to the magnitudes of the direct forces generated by the three groups of wind measurement components on the torsion spring.

[0022] 3. With the first wind measurement component, the second wind measurement component, and the third wind measurement component set, when wind measurement is required, the first blades, the second blades, and the third blades on the three groups of wind measurement components will all be deflected under the influence of wind force. However, the deflection rotation speed of the first blades is greater than that of the second blades and the third blades, and the deflection rotation speed of the second blades is greater than that of the third blades. Moreover, the first blades, the second blades, and the third blades are all affected by the torsional resistance of the first torsion spring, the second torsion spring, and the third torsion spring, and the intensity of the torsional resistance influence increases in sequence. Thus, phased measurement can be achieved, and the measurement includes three gears, thereby improving the accuracy of its measurement. Accordingly, corresponding solutions can be given in a timely manner according to the gear measurement, improving the safety of subsequent use, and thus increasing the utilization rate.

[0046] Please refer particularly to Figure 1 、 2 、 3, 4, 5, and 7. The second kit 604 is located outside the second connecting piece 503 and is movably connected to the second connecting piece 503.

[0047] The working principle of the present utility model is as follows: By utilizing the provided first torsion spring 406, second torsion spring 507, and third torsion spring 605, the elastic potential energies of the first torsion spring 406, second torsion spring 507, and third torsion spring 605 decrease in sequence and just form three grades. When the wind blows, the first fan blade 404 rotates under the influence of the wind force and directly drives the first sleeve 401 and the first convex ring 405 to rotate along the first annular chute 303, causing the first torsion spring 406 to be deformed by force and directly exerting a force on the tension contact rod.

Then, according to the corresponding tension measurement module 302, the corresponding tension value is obtained, and thus the corresponding wind force value can be obtained. When the wind force reaches the third grade, it will cause the third fan blade 603 to be driven by force to rotate the sleeve rod 601, causing the third torsion spring 605 to be deformed by force and directly exerting a force on the tension contact rod. Then, according to the corresponding tension measurement module 302, the corresponding tension value is obtained, and thus the corresponding wind force value can be obtained. Therefore, the magnitude of the wind force can be measured based on the direct force exerted on the torsion spring by the three groups of wind measurement components.
