Description

Technical Field

[0001] This utility model relates to the field of power system inspection and early warning equipment, and in particular to a real-time early warning device for power inspection. Background Technology

[0002] Electrical equipment in substations, power distribution rooms and other locations needs to be inspected regularly. Traditionally, this work is mainly done manually. Inspection personnel need to enter the site according to the plan and inspect the equipment by visual observation and using tools such as handheld thermometers.

[0003] However, manual inspection methods have limitations such as low efficiency, time and labor consumption, missed inspections, misjudgments, and potential safety hazards to workers. To overcome the shortcomings of manual inspection, the power operation and maintenance field is actively promoting the application of intelligent and automated technologies. Existing technologies, such as the utility model patent with Chinese patent authorization announcement number CN218719855U, disclose a real-time monitoring device for power engineering with early warning function. This device activates the drive motor of the mounting base, causing the base plate on the top surface of the mounting base to rotate the camera, enabling the camera to monitor without blind spots. By controlling the hydraulic rod, the hydraulic rod can move the connecting block up and down, and the connection is made via a Y-shaped connecting plate and the upper connecting block. The hinged pin allows the camera to move up and down for convenient all-around monitoring. When the camera detects an alarm, it transmits data via wire 2 to a buzzer and flashing light. The buzzer and flashing light then issue commands based on the received data, activating an alarm sound and flashing an alarm light to alert personnel. The mounting base and cross-shaped mounting plate can be separated by removing the bolts connecting them. The adjusting pin can also be separated from the lower connecting block, allowing the camera to be removed for easy maintenance and repair.

[0004] The existing inspection and early warning devices described above are generally unable to adapt to the complex equipment layout within substations, making it difficult to move flexibly in complex equipment environments and achieve accurate multi-angle observations. At the same time, the adjustment range of the camera unit is limited, making it difficult to simultaneously meet the needs of large-scale inspections and focusing on specific equipment details, thus resulting in certain usage defects. Therefore, this application proposes a real-time early warning device for power inspection, which can adapt to complex indoor and outdoor power equipment environments, has a more flexible range of movement, a more comprehensive observation perspective, and can achieve efficient real-time early warning. Summary of the Invention

[0005] The core of this invention lies in the ability of the walking component to flexibly move the monitoring unit, and the adjustable monitoring angle and range of the monitoring unit, thus solving the problem in existing technologies where inspection and early warning devices struggle to maneuver flexibly in complex equipment environments and achieve accurate multi-angle observation. Furthermore, the monitoring unit employs a combination of multiple monitoring methods, enabling it to provide more timely and reliable monitoring and early warning.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A real-time early warning device for power line inspection includes a rail and a traveling assembly. The traveling assembly is movably connected to the outside of the rail and includes a mounting box surrounding the outside of the rail. A connecting wheel and a balance wheel are rotatably connected inside the mounting box, and the connecting wheel and balance wheel are respectively located on both sides of the rail. A first servo motor is fixedly mounted on the outer surface of the mounting box, and the output end of the first servo motor is fixedly connected to the rotating shaft of the connecting wheel. The rail includes a connecting surface facing the connecting wheel and an abutting surface facing the balance wheel. The connecting surface has convex tooth structures evenly distributed to cooperate with the connecting wheel, and the connecting wheel is meshed with the rail through the connecting surface. The traveling assembly also includes a ball rotatably connected to the top surface of the inner side of the mounting box, and the ball rolls in contact with the top surface of the rail. The bottom of the mounting box is fixedly mounted with a first electric telescopic rod, and the bottom telescopic end of the first electric telescopic rod is fixedly connected to a lifting frame. The bottom end of the lifting frame is fixedly connected to a fixed frame, and the bottom end of the fixed frame is connected to a mounting plate. The bottom surface of the mounting plate is fixedly mounted with a controller and a buzzer. The bottom end of the mounting plate is also equipped with a monitoring unit, which includes a visible light camera.

[0008] In an exemplary embodiment, the contact surface is smooth, and the balance wheel makes rolling contact with the contact surface.

[0009] In an exemplary embodiment, a spherical groove is provided on the inner top surface of the mounting box to mate with a ball. The ball is inserted into the spherical groove with a gap fit, and the connection forms a spherical kinematic pair, which allows the ball to rotate in any direction around the center of the spherical groove within the space defined by the spherical groove. The center position of the ball is constrained and fixed by the spherical groove, and part of the ball structure protrudes from the spherical groove and rolls in contact with the top surface of the hanging rail.

[0010] In an exemplary embodiment, the inner top surface of the mounting box is evenly distributed with round beads that provide support for the mounting box.

[0011] In an exemplary embodiment, the bottom end of the fixed frame is connected to the mounting plate by a hinge. A second electric telescopic rod is provided on one side of the fixed frame, and one end of the second electric telescopic rod is rotatably connected to the inner side of the lifting frame, while the other end of the second electric telescopic rod is hinged to the mounting plate.

[0012] As a further improvement of this application, the monitoring unit also includes an infrared thermal imager and an ultrasonic obstacle avoidance radar. The infrared thermal imager is fixedly installed on one side of the visible light camera, and the ultrasonic obstacle avoidance radar is fixedly installed on the other side of the visible light camera. The visible light camera, the infrared thermal imager, and the ultrasonic obstacle avoidance radar are all facing the same direction.

[0013] As a further improvement of this application, an LED light strip is fixedly connected to the outer surface of the mounting plate, and the LED light strip is arranged in a wraparound manner along the outer edge of the mounting plate.

[0014] In an exemplary embodiment, a second servo motor is also provided between the mounting plate and the monitoring unit. The second servo motor is fixedly mounted on the bottom surface of the mounting plate, and the output end of the second servo motor is fixedly connected to the monitoring unit.

[0015] As a further improvement of this application, a positioning frame is provided on one side of the first electric telescopic rod, parallel to the axis of the first electric telescopic rod. The top of the positioning frame is fixedly connected to the bottom end face of the mounting box. The inside of the lifting frame is provided with a through hole structure that cooperates with the positioning frame, and the lifting frame is slidably connected to the outside of the positioning frame through the through hole structure.

[0016] Compared with existing technologies, the advantages of this utility model are: 1. This solution involves mounting a rail above the power system and driving the connecting wheel to rotate via a first servo motor. This causes the connecting wheel to mesh with the connecting surface, while the balance wheel rolls into contact with the contact surface. This allows the entire walking component to move outside the rail. Furthermore, the rail can be set in a straight line or a curved path, allowing the walking component to move along the direction of the rail. This facilitates flexible movement in complex equipment environments and enables a wider and more flexible inspection range.

[0017] 2. This solution uses the extension and retraction of the second electric telescopic rod to control the rotation of the mounting plate, thereby adjusting the shooting angle of the monitoring unit. At the same time, the second servo motor drives the monitoring unit to rotate, which can adjust the shooting direction of the monitoring unit, enabling more accurate multi-angle monitoring. The monitoring unit monitors the alarm screen and transmits the data to the controller. The controller receives the data and issues instructions, causing the buzzer to receive the signal and emit an alarm sound. At the same time, the LED light strip starts flashing to alert the staff. Furthermore, by combining visible light cameras, infrared thermal imagers, and ultrasonic obstacle avoidance radar, multiple monitoring methods can effectively avoid environmental interference and provide more timely and reliable monitoring and early warning effects. This improves the automation level and safety protection capabilities of power equipment status monitoring, and plays an early warning role in identifying potential faults and safety hazards such as equipment overheating, mechanical damage, and foreign object intrusion, thus ensuring power supply reliability.

[0020] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0021] First implementation method: Please see Figure 1 and Figure 3 As shown, a real-time early warning device for power line inspection includes a rail 1 and a traveling assembly 2. The traveling assembly 2 is movably connected to the outside of the rail 1, and the traveling assembly 2 includes a mounting box 201 that surrounds the outside of the rail 1, specifically as shown in the figure. Figure 4 and Figure 5As shown, the mounting box 201 is rotatably connected to a connecting wheel 203 and a balance wheel 204, and the connecting wheel 203 and the balance wheel 204 are respectively located on both sides of the hanging rail 1. A first servo motor 202 is fixedly mounted on the outer surface of the mounting box 201, and the output end of the first servo motor 202 is fixedly connected to the rotating shaft of the connecting wheel 203. The first servo motor 202 can drive the connecting wheel 203 to rotate inside the mounting box 201. The first servo motor 202 adopts existing technology, and a suitable model of motor can be selected and set by those skilled in the art, such as AKM series servo motor products. Specific examples Figure 5 As shown, the hanging rail 1 includes a connecting surface 101 facing the connecting wheel 203 and an abutting surface 102 facing the balance wheel 204. Simultaneously, the connecting surface 101 has evenly spaced toothed structures that mate with the connecting wheel 203, and the connecting wheel 203 is engaged with the hanging rail 1 through the connecting surface 101. Figure 4 and Figure 5 As shown, with the abutment surface 102 being a smooth surface, when the first servo motor 202 drives the connecting wheel 203 to rotate, the connecting wheel 203 and the balance wheel 204 respectively abut against both sides of the hanging rail 1. The connecting wheel 203 engages with the connecting surface 101, while the balance wheel 204 rolls against the abutment surface 102, thereby causing the entire traveling assembly 2 to move outside the hanging rail 1. Specifically, as shown... Figure 1 and Figure 6 As shown, the hanging rail 1 can be set in a straight line or in a curved line, and the traveling component 2 can move along the setting direction of the hanging rail 1; Furthermore, the walking assembly 2 also includes a ball 205 rotatably connected to the top surface of the inner side of the mounting box 201, and the ball 205 rolls in contact with the top surface of the hanging rail 1, thus engaging... Figure 4 and Figure 5 As shown, the inner top surface of the mounting box 201 has a spherical groove that mates with the ball 205. The ball 205 is inserted into the spherical groove with a clearance fit. This connection forms a spherical kinematic pair, allowing the ball 205 to rotate in any direction around the center of the spherical groove within the space defined by the spherical groove. The center position of the ball 205 is constrained and fixed by the spherical groove. When the traveling component 2 moves outside the hanging rail 1, the part of the ball 205 protruding from the spherical groove rolls into contact with the top surface of the hanging rail 1, providing support for the mounting box 201. Furthermore, the balls 205 can be evenly distributed between the hanging rail 1 and the mounting box 201, improving the support effect for the mounting box 201. Specific examples Figure 3As shown, a first electric telescopic rod 3 is fixedly installed at the bottom of the mounting box 201, and a lifting frame 4 is fixedly connected to the bottom telescopic end of the first electric telescopic rod 3. Meanwhile, a fixing frame 5 is fixedly connected to the bottom of the lifting frame 4, and a mounting plate 7 is connected to the bottom of the fixing frame 5. Figure 3 and Figure 6 As shown, the bottom end of the fixed frame 5 is connected to the mounting plate 7 by a hinge. A second electric telescopic rod 6 is provided on one side of the fixed frame 5. One end of the second electric telescopic rod 6 is rotatably connected to the inner side of the lifting frame 4, and the other end of the second electric telescopic rod 6 is hinged to the mounting plate 7. By extending and retracting the second electric telescopic rod 6, the mounting plate 7 can be controlled to rotate around the hinge position between the mounting plate 7 and the fixed frame 5, thereby controlling the shooting angle of the monitoring unit 9. Specific examples Figure 2 As shown, a monitoring unit 9 is also provided at the bottom of the mounting plate 7. The monitoring unit 9 includes a visible light camera 901. Furthermore, the monitoring unit 9 also includes an infrared thermal imager 902 and an ultrasonic obstacle avoidance radar 903. The monitoring height of the monitoring unit 9 can be adjusted by extending and retracting the first electric telescopic rod 3. The infrared thermal imager 902 is fixedly installed on one side of the visible light camera 901, and the ultrasonic obstacle avoidance radar 903 is fixedly installed on the other side of the visible light camera 901. The visible light camera 901, the infrared thermal imager 902, and the ultrasonic obstacle avoidance radar 903 face the same direction. By using the visible light camera 901, the infrared thermal imager 902, and the ultrasonic obstacle avoidance radar 903 in combination, environmental interference can be effectively avoided and the monitoring and early warning effect can be improved. Combination Figure 1 and Figure 2 As shown, a controller 10 and a buzzer 11 are fixedly mounted on the bottom surface of the mounting plate 7. The controller 10 is electrically connected to the monitoring unit 9. The controller 10 is electrically connected to the buzzer 11 through a drive switch. Furthermore, an LED light strip 12 is fixedly connected to the outer surface of the mounting plate 7, and the LED light strip 12 is arranged in a ring around the outer edge of the mounting plate 7. Among them, the buzzer 11 can be a product of model nd16-22fs, the infrared thermal imager 902 can be a YosenX series online temperature measurement infrared thermal imager, the ultrasonic obstacle avoidance radar 903 can be a product of model Radiolink SUI04, and the controller 10 can be a programmable logic controller or an Internet of Things controller, such as an ESP32 Internet of Things controller. At the same time, the working status of the electrical structures in this utility model (including the visible light camera 901, the infrared thermal imager 902, the ultrasonic obstacle avoidance radar 903, the buzzer 11 and the LED light strip 12) is controlled by the controller 10. The connection, control and function of the electrical structures and the controller 10 are all technologies known to those skilled in the art. Those skilled in the art can make reasonable settings according to the existing technology to meet the usage requirements of this utility model. Working principle: When using this real-time early warning device for power inspection, the mounting rail 1 is first fixedly installed above the equipment in the power system via a support mechanism. The mounting rail 1 can be set in a straight line or curved. Figure 1 and Figure 4 As shown, since the connecting wheel 203 and the balance wheel 204 are respectively located on both sides of the hanging rail 1, the first servo motor 202 drives the connecting wheel 203 to rotate inside the mounting box 201, so that the connecting wheel 203 engages with the connecting surface 101, while the balance wheel 204 rolls in contact with the abutment surface 102, thereby enabling the entire walking assembly 2 to move outside the hanging rail 1. Specifically, as shown... Figure 1 and Figure 6 As shown, the hanging rail 1 can be set in a straight line or in a curved line, and the walking component 2 can move along the setting direction of the hanging rail 1, which facilitates flexible movement in complex equipment environments; Specific examples Figure 3 As shown, the extension and retraction of the second electric telescopic rod 6 controls the rotation of the mounting plate 7 around the hinge position between the mounting plate 7 and the fixing frame 5, thereby controlling the shooting angle of the monitoring unit 9. Furthermore, the rotation of the monitoring unit 9 driven by the second servo motor 8 adjusts the shooting direction. The second servo motor 8 employs existing technology; those skilled in the art can select and configure a suitable model of motor, such as an AKM series servo motor. Figure 1 and Figure 2 As shown, the alarm screen is monitored by the monitoring unit 9 and the data is transmitted to the controller 10. The controller 10 receives the data and issues an instruction, causing the buzzer 11 to receive the switch signal and emit an alarm sound. At the same time, the LED light strip 12 starts to flash the alarm light to alert the staff.

[0022] Second implementation method: Please see Figure 1 As shown, unlike the first embodiment, in this embodiment, a positioning frame 13 parallel to the axis of the first electric telescopic rod 3 is provided on one side of the first electric telescopic rod 3. Figure 6 and Figure 7 As shown, the top end of the positioning frame 13 is fixedly connected to the bottom end face of the mounting box 201. Meanwhile, the inside of the lifting frame 4 is provided with a through hole structure that cooperates with the positioning frame 13, and the lifting frame 4 is slidably connected to the outside of the positioning frame 13 through the through hole structure. Working principle: In this embodiment, when the first electric telescopic rod 3 extends and retracts to control the lifting frame 4, the mounting plate 7 and the monitoring unit 9 to move up and down, the positioning frame 13 limits the lifting frame 4, improves the stability of the lifting frame 4 during the lifting process, thereby reducing the shaking of the monitoring unit 9 during the lifting process and improving the monitoring stability.

[0023] The above are merely preferred embodiments of this utility model; they encompass all the protection scope of this utility model.
