Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission tower state monitoring, in particular to a sensor mounting assembly and method for power transmission tower. BACKGROUND

[0002] In the intelligent operation and state monitoring of power transmission lines, installing various sensors (such as inclination, vibration, image, and micro-weather sensors) on the power transmission tower is a key means to obtain real-time tower structure health and environmental information. However, the existing sensor installation and deployment method on the power transmission tower has many significant defects, which restricts the large-scale, efficient, and safe application of the monitoring system.

[0003] The traditional installation method mainly relies on manual climbing of the tower or using large machinery (such as cranes) for high-altitude work. The manual climbing method is not only inefficient, but also poses a great threat to the personal safety of the workers, especially in adverse weather or complex terrain conditions. The use of large machinery is subject to on-site road conditions and operating space, is costly, and has poor flexibility. In addition, whether manual or mechanical, a long equipment installation and debugging time is required, which cannot meet the needs of rapid and batch deployment of sensors. Therefore, there is an urgent need for an installation assembly that can adapt to new operation modes (such as unmanned aerial vehicle assistance) to achieve safe and efficient aerial deployment.

[0004] Existing sensor mounting clamps or brackets are usually designed simply and lack versatility and adjustability. Most clamps use a bolt directly to clamp or weld fixedly, which requires workers to accurately align holes and laboriously tighten in a dangerous high-altitude position, making the operation extremely inconvenient. At the same time, such fixed structures are often difficult to adapt to different specifications and different inclination angles of angle steels or components on the power transmission tower, which can easily lead to insecure installation or damage to the tower material or the sensor body due to stress concentration in long-term operation. An installation and fixing mechanism that has multi-dimensional and fine adjustment capabilities and can quickly and reliably adapt to different tower materials is another problem that needs to be solved in the current technology.

[0005] Finally, the power supply and integration of existing sensors are also relatively backward. Sensors are usually installed and powered independently (such as using disposable batteries or small solar panels), which leads to a cluttered line on the tower, frequent battery replacement and maintenance, and insufficient long-term endurance. Data collection is often in a dispersed state, lacking a unified data collection and forwarding hub, increasing system complexity and operation and maintenance costs. Therefore, developing an integrated installation platform that integrates power supply, control, and sensing functions and has sustained self-power supply capability is of great significance for building stable, reliable, and maintenance-free power transmission tower monitoring nodes.

[0024] A sensor mounting assembly for power transmission tower, the core is an installation frame 1 composed of an I-shaped placement frame 11 made of I-shaped steel. The installation frame 1 serves as the bearing base of the whole assembly, and its top is fixedly installed with a central control assembly 2 through bolts, which serves as the control and power supply center of the system. In order to adapt to the transportation and deployment of UAV, two UAV supports 3 are symmetrically fixed on the two sides of the installation frame 1 through bolts, which are used to connect with the docking mechanism of the UAV belly. In order to realize the horizontal position adjustment of the installation assembly relative to the angle steel of the power transmission tower, a set of length adjusting assembly 5 is installed on the two sides of the installation frame 1, which can be extended and retracted in the horizontal direction. At the bottom of each set of length adjusting assembly 5, a set of depth adjusting assembly 601 is hinged, so that the installation assembly can be adjusted in pitch angle. Finally, on the side of the depth adjusting assembly 601 facing the main body of the power transmission tower, a fixing assembly 7 is installed, which firmly locks the whole sensor mounting assembly on the angle steel of the power transmission tower through mechanical clamping. In addition, in order to provide continuous power for the system, solar energy assemblies 4 are installed at the two ends of the mounting frame 1 respectively, which are used to collect solar energy and convert it into electric energy.

[0025] The central control assembly 2 is composed of an electrical mounting plate 21, the electrical mounting plate 21 is fixedly connected on the top of the I-shaped placement frame 11, the top of the electrical mounting plate 21 is respectively provided with a central control module 22 and a battery module 23, and the top of the electrical mounting plate 21 is fixedly connected with a sensor mounting plate 24 through bolts.

[0026] The central control assembly 2 is specifically composed of a rectangular electrical mounting plate 21. The electrical mounting plate 21 is directly fastened to the top surface of the center area of the I-shaped placement rack 11 by a plurality of bolts. On the top surface of the electrical mounting plate 21, two large core electrical modules are installed side by side: one is a central control module 22, which integrates a microprocessor, a wireless communication module and a data acquisition unit inside, responsible for coordinating the work of all sensors, processing data and returning through a wireless network; the other is a battery module 23, which is a rechargeable lithium battery pack, providing operating power for the sensors, controllers and communication modules of the entire system. In order to centrally install monitoring sensors, a sensor mounting plate 24 is also bolted to the top of the electrical mounting plate 21, one side of the central control and battery module 23, various types of inclination, vibration, temperature and humidity sensors can be integrated and installed on this plate, and connected to the central control module 22 through a cable.

[0027] The unmanned aerial vehicle support 3 is composed of a lap joint support 31, which is fixedly connected to one side of the mounting rack 1. The top of the lap joint support 31 movably sheaths a sleeve pipe 32, and the top of the sleeve pipe 32 is fixedly connected with an unmanned aerial vehicle hook 33.

[0028] The specific structure of the unmanned aerial vehicle support 3 is as follows: an L-shaped lap joint support 31 is bolted to the side of the mounting rack 1 through its vertical edge. On the horizontal part of the top of the lap joint support 31, a vertical sleeve pipe 32 is movably sheathed, which can slide or rotate up and down within a certain range to fine-tune the position. The top end of the sleeve pipe 32 is welded or fixed with a specially designed unmanned aerial vehicle hook 33, which is usually in the shape of a barb or has a quick release interface. When deployed, the hoisting mechanism of the unmanned aerial vehicle is lowered and hooks or locks the unmanned aerial vehicle hook 33, so that the entire installation assembly can be hoisted to the target position of the power transmission tower. The movable connection design of the sleeve pipe 32 and the lap joint support 31 allows the assembly to have a certain degree of freedom in swinging during hoisting, which is beneficial to stability.

[0029] The solar energy assembly 4 is composed of a solar panel connecting rack 41, which is fixedly connected to the top of the I-shaped placement rack 11. The top of the solar panel connecting rack 41 is provided with a solar panel body 42.

[0030] The solar energy assembly 4 mainly consists of a support structure and an energy conversion component. A solar panel connecting frame 41 is fixed to the top of one end of the I-shaped placing frame 11 through its base. The inclination angle of the connecting frame is designed to better receive sunlight after installation. On the inclined surface of the solar panel connecting frame 41, a solar panel body 42 is installed, which is packaged by photovoltaic cells. When sunlight shines on the surface of the solar panel body 42, a photovoltaic effect generates direct current. The generated electric energy is stored in the battery module 23 in the central control assembly 2 through the wire, or directly powers the system after conversion, thereby realizing energy self-sufficiency and prolonging the continuous working time of the equipment in the wild.

[0031] The length adjusting assembly 5 consists of a side connecting plate 501 and a length adjusting plate 509. The side connecting plate 501 is fixedly connected to one side of the I-shaped placing frame 11 by bolts. The inside of the side connecting plate 501 is provided with a first internal threaded block 502; The inside of the length adjusting plate 509 is rotatably installed with a first limiting rotating block 505. The first limiting rotating block 505 is fixedly connected with a first rotating shaft 503. One end of the first rotating shaft 503 is fixedly connected with a first rotating disc 506. The other end of the first rotating shaft 503 is fixedly connected with a first threaded connecting rod 504, which is threadedly connected in the inside of the first internal threaded block 502.

[0032] The length adjusting assembly 5 is the key mechanical structure for realizing the horizontal expansion of the installation assembly. It mainly includes a side connecting plate 501 fixed to the side of the I-shaped placing frame 11 and a length adjusting plate 509 movable relative thereto. In the inside of the side connecting plate 501, a first internal threaded block 502 is embedded. A first limiting rotating block 505 is rotatably installed in the inside of the length adjusting plate 509. One end of a first rotating shaft 503 is fixedly connected with the first limiting rotating block 505, and the other end penetrates through the length adjusting plate 509, and the outside end of the first rotating shaft 503 is fixedly connected with a first rotating disc 506 for manual rotation operation, and the inside end of the first rotating shaft 503 is coaxially fixedly connected with a first threaded connecting rod 504. When the length needs to be adjusted, the first rotating disc 506 is rotated to drive the first rotating shaft 503 and the first threaded connecting rod 504 to rotate synchronously. Since the first threaded connecting rod 504 is screwed into and engaged in the fixed first internal threaded block 502, the rotation movement is converted into the linear advancing and retreating movement of the first threaded connecting rod 504 and the entire length adjusting plate 509 relative to the side connecting plate 501, thereby realizing the stepless adjustment of the horizontal length.

[0033] The inside of the side connecting plate 501 is provided with two symmetrically arranged first limiting holes 508. One side of the length adjusting plate 509 is fixedly connected with two symmetrically arranged first identification limiting shafts 510. The first identification limiting shafts 510 are slidingly assembled in the inside of the first limiting holes 508. The first threaded connecting rod 504 is threadedly sleeved with a first locking bolt 507.

[0034] To ensure the smoothness during the length adjustment process and prevent the rotation of the adjusting plate, two symmetrical first limiting holes 508 are opened in the inside of the side connecting plate 501. Correspondingly, two first identification limiting shafts 510 are fixedly installed on the side of the length adjusting plate 509 facing the side connecting plate 501, which are in position correspondence with the first limiting holes 508. When adjusting the length, the first identification limiting shafts 510 are accurately inserted and slide along the first limiting holes 508, which play the role of guiding and preventing circumferential rotation. The scale can be marked on the first identification limiting shafts 510 to indicate the amount of expansion. After adjusting to the required position, in order to lock, a first locking bolt 507 is threadedly sleeved on the first threaded connecting rod 504. By tightening the bolt, the end thereof will abut against the side connecting plate 501 or the first internal threaded block 502, generating a large frictional resistance, so as to lock the rotation freedom of the first threaded connecting rod 504 and fix the position of the entire length adjusting plate 509.

[0035] The depth adjusting assembly 601 is composed of a bottom connecting shaft 601 and a connecting plate 607. The bottom connecting shaft 601 is fixedly connected at the bottom of the length adjusting plate 509 by a bolt. The bottom of the bottom connecting shaft 601 is fixedly connected with a bottom connecting piece 602. The bottom connecting piece 602 movably hingedly connects with a hinged plate 603. The hinged plate 603 and the bottom connecting piece 602 are jointly connected with a torsion spring 604.

[0036] The depth adjusting assembly 601 is responsible for the adjustment of the installation assembly pitch angle. The main body includes the upper bottom connecting shaft 601 and the lower connecting plate 607. The bottom connecting shaft 601 is fixedly connected at the bottom end of the length adjusting plate 509 by a bolt. The bottom end of the bottom connecting shaft 601 is welded with a bottom connecting piece 602. A hinged plate 603 is movably hingedly connected with the bottom connecting piece 602 by a pin shaft. The two can rotate relative to each other around the hinge point. Between the hinged plate 603 and the bottom connecting piece 602, a torsion spring 604 is also jointly connected. The torsion spring 604 provides an initial torsion force, which helps to maintain a certain default angle between the hinged plate 603 and the bottom connecting piece 602 in the unlocked state, and can provide a certain damping feeling during adjustment to prevent the hinged plate 603 from shaking freely.

[0037] The inside of the hinged plate 603 is respectively provided with a second internal threaded block 605 and two symmetrical second limiting holes 606. The inside of the connecting plate 607 is rotatably installed with a second limiting rotating block 611. The second limiting rotating block 611 is fixedly connected with a second rotating shaft 609. The two ends of the second rotating shaft 609 are respectively fixedly connected with a second rotating disc 612 and a second threaded connecting rod 610. The top of the connecting plate 607 is fixedly connected with two symmetrical second identification limiting shafts 608. The second threaded connecting rod 610 is threadedly connected in the inside of the second internal threaded block 605. The second identification limiting shafts 608 are slidingly assembled in the inside of the second limiting holes 606. The second threaded connecting rod 610 is threadedly connected with a second locking bolt 613.

[0038] The angle fine adjustment and locking mechanism of the depth adjustment is integrated between the hinged plate 603 and the connecting plate 607. Inside the hinged plate 603, a second internally threaded block 605 is embedded, and two symmetrical second limiting holes 606 are opened. Inside the connecting plate 607, a second limiting rotating block 611 is rotatably installed through a bearing. The second rotating shaft 609 is fixed at one end with the second limiting rotating block 611, and the outer side end is fixed with a second rotating disc 612, and the inner side end is coaxially fixed with a second threaded connecting rod 610. The top of the connecting plate 607 is fixed with two second identification limiting shafts 608. When the angle is adjusted, the second rotating disc 612 is rotated to drive the second threaded connecting rod 610 to rotate. Since the second threaded connecting rod 610 is screwed into the second internally threaded block 605 in the hinged plate 603, the rotation causes the connecting plate 607 to move linearly along the axis relative to the hinged plate 603. This linear movement, because the second identification limiting shaft 608 is simultaneously slidingly guided along the second limiting hole 606, pushes the connecting plate 607 to swing around the hinge point, thereby changing the pitch angle of the connecting plate 607 and the subsequent fixed assembly 7 relative to the mounting frame 1. After adjustment, the second locking bolt 613 threaded on the second threaded connecting rod 610 is tightened to press the end face of the hinged plate 603, so as to realize firm locking of the angle.

[0039] The fixed assembly 7 is composed of a lap plate 71. The lengths of the lap plates 71 on both sides are the same as the heights of the tower top angle steels on both sides, respectively. The lap plate 71 is fixedly connected to one side of the connecting plate 607 through bolts. The upper and lower ends of the lap plate 71 are rotatably installed with rotating shafts 72. A plurality of equally spaced half gears 73 are fixedly sleeved on the outer circumferential surfaces of the rotating shafts 72. A top abutting plate 74 and a bottom abutting plate 75 are fixedly sleeved on the outer circumferential surfaces of the rotating shafts 72 at the upper and lower ends, respectively. The two bottom abutting plates 75 are abutted with each other after rotation. The lap plate 71 is internally slidably assembled with a long rack 76 corresponding in number to the half gears 73 on a single rotating shaft 72. The long rack 76 is engaged with the two half gears 73 on the same side thereof.

[0040] The fixed assembly 7 is the mechanism that finally clamps the whole mounting assembly on the angle steel of the power transmission tower. Its main body is a vertical lap plate 71 fixed on the side of the connecting plate 607 of the depth adjusting assembly 601 by bolts. In the bearing seats on the upper and lower ends of the lap plate 71, each is horizontally installed with a rotatable rotating shaft 72. On the outer circumferential surface of each rotating shaft 72, a plurality of axially equidistantly arranged half gears 73 are fixedly sleeved. In particular, the uppermost rotating shaft 72 is extended at one end and fixed with a top connecting plate 74, and the lowermost rotating shaft 72 is fixed at the corresponding position with a bottom connecting plate 75, the top connecting plate 74 and the bottom connecting plate 75 are parallel to each other and constitute the jaw for clamping the angle steel. Inside the lap plate 71, corresponding to each pair of upper and lower aligned half gears 73, a long rack 76 is slidingly installed. Each long rack 76 is engaged with the two half gears 73 above and below it at the same time. When one of the rotating shafts 72 is rotated by an external tool such as a wrench, for example, the shaft driving the top connecting plate 74, all the half gears 73 on the shaft rotate synchronously, driving all the long racks 76 engaged therewith to move horizontally. The horizontal movement of the long rack 76 drives all the half gears 73 on the other rotating shaft 72 engaged therewith to rotate reversely and synchronously, so that the bottom connecting plate 75 and the top connecting plate 74 move towards or away from each other, realizing stable and multi-point synchronous clamping and loosening of angle steels of different thicknesses.

[0041] Working principle: the unmanned aerial vehicle is lowered by its lifting mechanism and hooks or locks the unmanned aerial vehicle claws 33 installed on the unmanned aerial vehicle brackets 3 on both sides of the mounting rack 1, wherein each unmanned aerial vehicle bracket 3 is composed of a lap bracket 31 fixed on the side of the mounting rack 1, a sleeve pipe 32 movably sleeved on the top of the lap bracket 31, and an unmanned aerial vehicle claw 33 fixed on the top end of the sleeve pipe 32. Through the movable connection of the sleeve pipe 32, the assembly remains stable swing during lifting. After reaching the target angle steel near the power transmission tower, position and attitude adjustment is started: first, the operator simultaneously or separately operates the length adjustment assembly 5 installed on both sides of the mounting rack 1, and each length adjustment assembly 5 includes a side plate 501 fixed on the side of the I-shaped rack 11 and a movable length adjustment plate 509. The first turntable 506 fixed on the length adjustment plate 509 is rotated to drive the first rotating shaft 503 fixedly connected thereto to rotate, and the other end of the first rotating shaft 503 is fixed with a first threaded connecting rod 504 which is screwed into the first internal threaded block 502 fixed in the side plate 501. The rotary motion causes the first threaded connecting rod 504 to drive the entire length adjustment plate 509 to move linearly in the horizontal direction, and in this process, the two first identification limiting shafts 510 fixed on one side of the length adjustment plate 509 slide in the two first limiting holes 508 symmetrically opened on the side plate 501 to ensure stable movement without rotation. After adjusting to the required transverse distance, the first locking bolt 507 threaded on the first threaded connecting rod 504 is tightened to abut against the length adjustment plate 509 to lock the position of the length adjustment plate 509.

The second threaded connecting rod 610 is screwed into the second internal threaded block 605 arranged in the hinged plate 603, and the rotation drives the two second identification limiting shafts 608 on the connecting plate 607 and the hinged plate 603 to slide along the two second limiting holes 606 opened on the hinged plate 603, forcing the connecting plate 607 to swing around the hinge point, thereby accurately adjusting the pitch angle of the connecting plate 607 and the components connected thereto. After the angle is adjusted, the second locking bolt 613 threaded on the second threaded connecting rod 610 is tightened to abut against the hinged plate 603 to achieve angle locking. After completing the attitude adjustment, the final mechanical fixation is performed: the side of the connecting plate 607 is fixed with the lap plate 71 of the fixing assembly 7 through a bolt.Inside the overlap plate 71, a rotating shaft 72 is rotatably installed at each of the upper and lower ends, a plurality of equally spaced half gears 73 are fixedly sleeved on each rotating shaft 72, the upper rotating shaft 72 is fixed at one end with a top connecting plate 74, and the lower rotating shaft 72 is fixed at the corresponding end with a bottom connecting plate 75. Corresponding to each pair of upper and lower half gears 73, a long rack 76 is slidingly installed inside the overlap plate 71, and each long rack 76 is engaged with the upper and lower half gears 73 at the same time. Rotate any rotating shaft 72 (such as the shaft driving the top connecting plate 74) using a tool, all half gears 73 on the shaft rotate synchronously, driving all long racks 76 engaged therewith to move horizontally; the movement of the long rack 76 drives all the half gears 73 on the other rotating shaft 72 engaged therewith to rotate reversely and synchronously, so that the bottom connecting plate 75 and the top connecting plate 74 move towards each other accurately, firmly clamping the angle steel of the power transmission tower. After installation and fixation, the system is started: the solar components 4 installed at both ends of the mounting frame 1 start to work, each solar component 4 includes a solar panel connecting frame 41 fixed on the top of the I-shaped placement frame 11 and a solar panel body 42 installed on the solar panel connecting frame 41, and the electric energy generated by the photovoltaic effect is transmitted to the central control component 2 through the wire.
