Description

Technical Field

[0001] The present invention relates to the technical field of transmission line detection, and particularly to an X-ray split-type detection device for four-split transmission lines. Background Art

[0002] In the field of power transmission, four-split transmission lines are widely used in high-voltage transmission lines to improve transmission efficiency and stability. The detection of four-split transmission lines is crucial. Among them, using X-ray photography for detection is a commonly used and effective means, which can clearly present the internal condition of the transmission line, timely detect potential defects, and ensure the safety and stability of power transmission.

[0003] Currently, when the split-type detection device for four-split transmission lines performs X-ray photography detection operations, it faces severe environmental challenges, especially the influence of weather factors. Under strong wind weather conditions, the stability problem of the detection device is particularly prominent. Due to its structural characteristics, the device is extremely vulnerable to the strong wind force perpendicular to the transmission line, and will swing greatly on the transmission line. The wind force in the horizontal direction of the transmission line will be resisted by the tension of the transmission line itself. At the same time, because the weight of the detection device is distributed along the length direction of the transmission line, its ability to resist the wind force in the length direction of the transmission line is relatively strong, that is, the swing of the detection device along the length direction of the transmission line is less. The swing perpendicular to the transmission line not only seriously affects the accuracy of detection, but more seriously, when the wind force is too large, the device may tip over and fall from the transmission line due to being unable to withstand the wind force. This will not only cause serious damage to the detection device itself, increase the high equipment repair and replacement costs, but also pose a great safety threat to the staff below, and is very likely to cause serious casualties.

[0004] Even under light wind weather conditions, it is difficult for the detection device to avoid being affected by the lateral wind force. Although the light wind will not cause the device to fall, it will cause the device to produce continuous small swings on the transmission line. This seemingly insignificant swing will have a negative impact on the stable state of the imaging plate on the transmission line. The instability of the imaging plate directly interferes with the shooting work of the X-ray instrument driven by the drone alone, resulting in a decrease in the quality of the X-ray images taken, such as blurring, double imaging, etc., which in turn brings many obstacles to the high-quality guiding detection work, making it difficult to accurately detect the subtle defects inside the transmission line and reducing the reliability and effectiveness of the detection work. Summary of the Invention

[0010] As a further optimization of the X-ray split detection device for a four-split power transmission line of the present invention: the transmission ratio of the first gear and the driven gear is less than one.

[0011] As a further optimization of the X-ray split detection device for four-split power transmission lines of the present invention: the transmission ratio of the second gear to the driving gear is greater than one.

[0012] As a further optimization of the X-ray split detection device for four-split power transmission lines of the present invention: the angle between the nail body of the supporting nail and the nail head of the supporting member is 45 to 50 degrees.

[0018] In the present invention, by arranging the driving fan blades and the driving member to cooperate with each other, the wind blocking cylinder rotatably mounted on the support pin is driven to rotate. When the wind blocking cylinder rotates, it will obstruct the wind on the side away from the support member, that is, the wind force Va, effectively reducing the flow rate when the wind force Va passes through, while the wind speed at the wind force Vb remains basically unchanged. Based on this flow rate difference, the wind blocking cylinder will apply a resultant force Fc perpendicular to the body of the support pin to the support pin. Since the support pin is arranged in an inclined state through the inclination block, the resultant force Fc can be decomposed into two component forces under the action of this inclined structure: a horizontal force Fd and a vertical force Fe. Among them, the horizontal force Fd will be offset by the interaction between the driving motor and the driving wheel included in the support member and the transmission line. Specifically, the driving motor drives the driving wheel to rotate on the transmission line, and the resistance generated by this rotation and the friction force with the transmission line, etc., can effectively balance the horizontal force Fd. And the vertical force Fe will press the support member against the transmission line, significantly enhancing the ability of the support member to resist wind under the action of lateral wind, enabling the support member to be stably held on the transmission line, effectively avoiding situations such as shaking, displacement or even falling due to the influence of wind, thereby ensuring the stability and reliability of the detection device during the detection process.

Detailed implementation manners

[0025] To better understand the present invention, the content of the present invention will be further clarified below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.

[0026] <Embodiment 1>

[0027] As Figure 1 and Figure 2 shown, a four-split X-ray split-type detection device is provided with a support member 1, which can not only support and connect the power transmission line, but also move flexibly on the power transmission line. A control component 6 is arranged on the support member 1 to facilitate operation by the staff; the docking member 2 is used to cooperate with the hoisting of the unmanned aerial vehicle; an imaging plate 4 is installed on the adjustment component 5, and by adjusting the position of the imaging plate 4, it can correspond to the power transmission lines at different positions, so as to cooperate with the X-ray camera controlled by the unmanned aerial vehicle to accurately photograph and detect the power transmission line.

[0028] Specifically, the docking member 2 can be hung by the unmanned aerial vehicle, driving the support member 1 and all the structures thereon to generate displacement, and hanging it on the power transmission line. The staff can conveniently control the movement of the device on the power transmission line according to the actual situation with the help of the control component 6 to comprehensively detect different positions of the power transmission line. In addition, a plurality of stability components 3 are arranged on the upper side surface of the support member 1, and these stability components 3 can press the support member 1 onto the power transmission line under the drive of wind. As Figure 3As shown in the figure, the stabilizing component 3 includes an inclination block 301 fixed to the top surface of the support 1. A support nail 305 is fixedly installed on the inclined surface of the inclination block 301. The support nail 305 is inclined and forms an angle of 45 degrees with the support 1. A wind blocking cylinder 302 is rotatably installed on the nail body of the support nail 305. A driving shaft 306 is rotatably provided on the nail head of the support nail 305. A driving fan blade 303 is fixedly provided on the outer peripheral surface of the driving shaft 306. The driving fan blade 303 realizes synchronous and co-rotational movement with the driving fan blade 303 through a driving member 304 provided on the nail head of the support nail 305. When the wind on one side blows the driving fan blade 303 to rotate in the opposite direction of the relative wind, the driving member 304 will drive the wind blocking cylinder 302 to rotate in the opposite direction of the relative wind at the same time, as Figure 3 shown. At this time, the wind blocking cylinder 302 will block the wind on the side of the support nail 305 away from the support 1, that is, the wind Va, and reduce the flow rate of the wind Va passing through the wind blocking cylinder 302, but will not block the flow rate of the wind Vb passing through the wind blocking cylinder 302. According to Bernoulli's law, where the flow rate is large, the pressure is small, and where the flow rate is small, the pressure is large. In this way, a pressure Fc perpendicular to the nail cone of the support nail 305 will be generated. Since the support nail 305 is inclined at 45 degrees, the pressure Fc can be decomposed into a force Fe perpendicular to the support 1 and a force Fd parallel to the support 1. The force Fd will be offset by the power limitation of the power transmission line slightly bent by the support of the support 1 and the equipment itself, so as to press the support 1 down onto the power transmission line to a certain extent and stabilize its own position. At the same time, the force Fe perpendicular to the support 1 will further press the support 1 down onto the power transmission line, not only further positioning the position of the support 1, reducing the possibility of the support 1 tipping over and falling from the power transmission line, but also assisting in positioning the position of the imaging plate 4 and keeping the imaging plate 4 stable, providing strong support for the high-quality power transmission line detection operation of the X-ray imager carried by the unmanned aerial vehicle. The driving member 304 here includes a transmission shaft 3045 rotatably provided on the nail head of the support nail 305, as Figure 4As shown, the two ends of the transmission shaft 3045 passing through the nail head of the support nail 305 are respectively matched with the driving shaft 306 and the wind blocking tube 302 through a transmission belt, so that when the driving blade 303 is driven by the wind, it can drive the wind blocking tube 302 to rotate, generating a force Fe to press the support member 1. When the wind direction is along the length direction of the transmission line, if the side corresponding to the Va wind force is on the windward side, since the driving blade 303 is tilted, its rotation will be relatively slow in a breeze state, and it may even only rotate occasionally. At this time, the wind force on the windward side is blocked, and the flow velocity is significantly reduced, while the wind force flow velocity on the side away from the windward side remains basically unchanged. Based on the principle of "high flow velocity and low pressure, low flow velocity and high pressure" in fluid mechanics, this difference in flow velocity will produce a pressure difference, which will then produce a top pressure effect on the support member 11, effectively limiting the position change of the support member 11. When the surface through which the wind force Vb passes becomes the windward surface, on the one hand, the inclined shape of the support nail 305, and on the other hand, the wind resistance of the support member 11, work together to make the wind force on the surface through which the wind force Vb passes be hindered, but the magnitude of the reduction in its flow rate is relatively small. At the same time, the wind flow rate of the surface through which the wind force Va passes is also relatively slightly affected by the above-mentioned blocking factors. According to the relationship between flow rate and pressure in fluid mechanics, it can be known that at this time, the pressure difference formed between the surface through which the wind force Vb passes and the surface through which the wind force Va passes is relatively small. The force generated by this small pressure difference that attempts to lift the support member 11 upward is also relatively weak, and can be almost completely offset by the gravity of the support member 11 itself. This means that the support member 11 will basically not be significantly affected by the pressure difference in this case, and can maintain a relatively stable state, ensuring that its position on the transmission line will not be significantly changed by this small pressure difference.

[0029] The support member 1 is composed of a U-shaped connecting frame 103 and a protective shell 104 provided on the horizontal section of the connecting frame 103. A plurality of inclination blocks 301 are fixedly installed on the top surface of the protective shell 104, and two driving wheels 107 that can be mounted on the transmission line are provided on its inner wall. These two driving wheels 107 are driven by two driving motors 108 provided on the protective shell 104 through a belt transmission assembly 109. The two driving motors 108 are controlled by a control assembly 6, so as to realize the displacement of the device on the transmission line and detect different positions of the transmission line. A locking member 105 is provided at the top of the protective shell 104, and this locking member 105 can be connected to the docking member 2, which is convenient for the drone to connect to the connecting frame 103, enabling the drone to hoist the connecting frame 103 onto the transmission line. Specifically, the docking member 2 includes a docking hook 201 connected to the locking member 105, and a positioning rod 202 is clamped at the bent portion at the top of the docking hook 201. The settings of the positioning rod 202 and the docking hook 201 can make the connection operation of the drone more convenient. First bending portions 101 and second bending portions 102 are respectively provided on the vertical lower end surface of the connecting frame 103, and the inclination directions of the first bending portion 101 and the second bending portion 102 are opposite, presenting an eight-shaped pattern. During the process of installing the connecting frame 103 onto the transmission line, this design facilitates the hoisting operation of the drone and places it onto the transmission line. The second bending portion 102 is connected to the control assembly 6, and one side of the connecting frame 103 corresponding to the first bending portion 101 is connected to the adjusting assembly 5, which can maintain the force balance on both sides of the connecting frame 103 corresponding to the first bending portion 101 and the second bending portion 102, further improving the stability of the connection between the connecting frame 103 and the transmission line and reducing the probability of the connecting frame 103 tipping over and falling on the transmission line.

[0030] The adjusting assembly 5 includes two sliding rails 502 provided on one side surface of the connecting frame 103 corresponding to the first bending portion 101. The two sliding rails 502 are connected with a displacement plate 501 through sliding blocks 505. The end of the displacement plate 501 passes through the protective shell 104 and is fixedly connected with an imaging plate 4. A pressing plate 506 for pressing an adjusting belt 503 is also provided on the displacement plate 501. The two ends of the adjusting belt 503 are respectively in transmission connection with a regulating motor 507 and an auxiliary wheel 504. The regulating motor 507 is fixedly installed on the inner wall of the protective shell 104. By driving the adjusting belt 503, it drives the displacement plate 501 to perform vertical displacement, and then drives the imaging plate 4 to move vertically, so as to detect the transmission lines at different height positions. The auxiliary wheel 504 is provided on a reinforcing beam 106, and the reinforcing beam 106 is fixedly installed between the two vertical sections on one side of the connecting frame 103 corresponding to the first bending portion 101. The auxiliary wheel 504 can keep the adjusting belt 503 in a taut state. Driven by the adjusting motor, it drives the adjusting belt 503 to rotate, so that the displacement plate 501 can stably perform vertical displacement and detect corresponding different transmission lines.

[0031] <Example 2>

[0032] Figure 3 and Figure 5 As shown in Figure 5 , this embodiment is basically similar to Embodiment 1, and the main difference lies in the structure of the driving member 304. In this embodiment, the driving member 304 includes a driving gear 3044 driven by a driving fan blade 303 cooperating with a driving shaft 306, and a driven gear 3041 fixedly connected to the top of the air blocking cylinder 302 for driving the air blocking cylinder 302 to rotate. The driving gear 3044 meshes with the second gear 3043, and the driven gear 3041 meshes with the first gear 3042. The first gear 3042 and the second gear 3043 are respectively installed at both ends of a transmission shaft 3045, and the transmission shaft 3045 is rotatably connected to the head of a support nail 305. In this way, when the wind force causes the driving fan blade 303 to rotate, through the mutual cooperation among the driving gear 3044, the second gear 3043, the first gear 3042, the transmission shaft 3045, the driving shaft 306306, and the driven gear 3041, the air blocking cylinder 302 can be driven to rotate synchronously and stably, thereby generating a component force Fe that vertically presses downward on the support member 1.

[0033] In addition, the transmission ratio of the driving gear 3044 to the second gear 3043 is greater than one. This design can reduce the initial starting force of the driving gear 3044 when driving the second gear 3043 to rotate; the transmission ratio of the driven gear 3041 to the first gear 3042 is less than 1, which can maintain the rotation speed of the air blocking cylinder 302, thereby increasing the resistance when the wind force Va passes through the air blocking cylinder 302, further reducing the flow rate of Va passing through the air blocking cylinder 302, and increasing the pressure on the side of the air blocking cylinder 302 corresponding to the wind force Va. In this way, the total force Fc acting on the support nail 305 can be increased, thereby increasing the component force Fe pressing on the support member 1 and further improving the stability of the support member 1 on the transmission line.

[0034] For the parts not clarified in the above embodiments, such as how to select and operate the types and models of the control component 6, the regulation motor 507, the driving motor 108, and the belt transmission component 109, they should all be understood as the prior art known or should be known to those skilled in the art. All of them in the present invention are common means in the prior art.

[0035] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which do not affect the essence of the present invention.
