Description

Technical Field

[0001] The present application relates to the technical field of power distribution detection, and in particular to a safety detection device for power distribution. Background Art

[0002] The safety of distribution facilities is crucial during routine maintenance and safety inspections of power systems. Regular safety inspections of electrical equipment are necessary, but traditional methods for power distribution safety inspections often rely on manual inspections or simpler automated equipment. These methods often suffer from inefficiency, limited coverage, and difficulty adapting to complex environments. With the acceleration of urbanization and the continuous expansion of distribution networks, efficient, accurate, and comprehensive safety inspections of distribution facilities have become increasingly important.

[0003] Among them, traditional detection equipment is mostly fixed and usually used to detect some specific electrical equipment, and its use has certain limitations. Some other movable detection equipment, due to its fixed structural design, is difficult to operate in a small space and requires a large turning radius to change the direction of travel, which greatly limits their application scenarios; secondly, when the detection device encounters road obstacles during detection, it is not only difficult to cross the obstacles, but will also be affected by the obstacles and find it difficult to move forward. At the same time, after being bumped by the obstacles, it is easy to cause operation interruption or equipment damage, affecting the continuity and safety of the detection work. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art: traditional detection equipment is mostly fixed and usually used to detect certain electrical equipment, which has certain limitations. Other mobile detection equipment, due to its fixed structural design, is difficult to operate in a small space and requires a large turning radius to change the direction of travel, which greatly limits their application scenarios. To this end, this application proposes a safety detection device for power distribution.

[0005] According to an embodiment of the present application, a safety detection device for power distribution includes a base, and a walking mechanism is rotatably installed at the four corners on the lower side of the base. A turntable is rotatably provided on the upper side of the base. The turntable is driven by a motor to drive the detection mechanism fixed on the upper end to rotate, and the walking path of the walking mechanism is adjusted according to the detection direction after the detection mechanism rotates. An outer ring is fixedly connected to the outer side of the turntable, and an obstacle clearing mechanism is installed on one side of the outer ring. Sensors are installed on all four sides of the base.

[0006] Furthermore, the walking mechanism includes a fixed rod rotatably connected to the base, a rotating rod 1 is rotatably provided on one side of the fixed rod, and moving wheels are installed at both ends of the rotating rod 1. The rotating shaft at the upper end of the fixed rod is fixedly connected to a gear plate, and the gear plate is engaged with a driving wheel rotating at the bottom of the base, and the driving wheel is driven by a motor.

[0007] Furthermore, a bevel gear 1 is fixedly connected to the middle section of the rotating rod 1, and a bevel gear 2 is rotatably provided on the fixed rod. The bevel gear 2 is driven by a motor and meshes with the bevel gear 1.

[0008] Furthermore, two groups of shock absorbers are installed on one side of the fixing rod.

[0009] Furthermore, the detection mechanism includes a hollow sleeve fixed on the upper side of the turntable, an adjustment rod is slidably arranged in the hollow sleeve, a detection device is installed on the upper end of the adjustment rod, a screw rod is rotatably arranged inside the hollow sleeve, the screw rod is driven by a motor and is threadedly connected to the adjustment rod.

[0010] Furthermore, limiting grooves are provided on both sides of the hollow sleeve, a limiting piece is fixedly provided at the bottom of the adjusting rod, both ends of the limiting piece pass through the limiting grooves, and a side rod is also provided on the upper side of the turntable, and the end of the limiting piece slides with the side rod.

[0011] Furthermore, the upper side of the detection device is protected by a protective cover.

[0012] Furthermore, the obstacle clearing mechanism includes a pair of levers rotatably arranged on the upper side of the outer ring, each lever is fixedly connected to a bevel gear three, a rotating rod two is rotatably mounted on the outer ring, both ends of the rotating rod two are respectively connected to bevel gear four, the two sets of bevel gear four are respectively engaged with the two sets of bevel gear three, the middle section of the rotating rod two is connected to the first gear, and the upper side of the outer ring is driven by the motor to drive the second gear, and the first gear and the second gear are engaged.

[0013] Furthermore, an outer plate is hinged to the end of the shifting rod, and an elastic member is connected between the outer plate and the shifting rod.

[0014] Furthermore, a top plate is fixedly provided at the lower end of the side rod.

[0015] The beneficial effects of this application are: by rotating the rotatable walking mechanism at the bottom of the base, the walking path is changed, allowing the device to change its direction of travel without a large turning radius. This greatly improves the maneuverability of the device in a small space, enabling it to easily cope with complex on-site environments. At the same time, in conjunction with the rotatable turntable, the turntable rotates with the detection mechanism to adjust the direction of detection, so that the detection mechanism can perform power distribution safety detection in any direction, ensuring all-round and multi-angle safety detection capabilities. In addition, sensors are used to monitor the road conditions ahead in real time, and when obstacles are detected, two sets of levers are automatically activated to expand outward for clearing, ensuring smooth passage of the walking mechanism, enhancing the device's ability to autonomously handle complex environments, reducing the risk of operation interruption due to obstacles, and improving detection efficiency.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0028] A safety detection device for power distribution according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0029] like Figures 1-9 As shown, a safety detection device for power distribution according to an embodiment of the present application includes a base 1, and a walking mechanism 2 is rotatably installed at the four corners on the lower side of the base 1. The walking mechanism 2 can adjust the walking path by rotation to meet the needs of the device for use in complex and narrow spaces.

[0030] refer to Figure 8 and Figure 9 As shown, the walking mechanism 2 includes a fixed rod 21 rotatably connected to the base 1. The fixed rod 21 is curved to optimize the maneuverability of the equipment in a narrow space. A rotating rod 24 is rotatably provided on one side of the fixed rod 21. Moving wheels 27 are installed at both ends of the rotating rod 24. A bevel gear 25 is fixedly connected to the middle section of the rotating rod 24. A bevel gear 26 is rotatably provided on the fixed rod 21. The bevel gear 26 is driven by a motor and engages with the bevel gear 25. Therefore, after the motor is started, the rotating rod 24 can be driven to rotate with the moving wheels 27 on both sides to realize the movement of the device.

[0031] In addition, a gear plate 22 is fixedly connected to the rotating shaft at the upper end of the fixed rod 21. The gear plate 22 is engaged with a driving wheel 23 rotating at the bottom of the base 1. The driving wheel 23 is driven by a motor. When the motor drives the driving wheel 23 to operate, it can cause the gear plate 22 to rotate with the fixed rod 21, thereby realizing precise control of the moving direction of the walking mechanism 2, so that the equipment can change the travel path without large-scale turns.

[0032] To further enhance the stability and durability of the device, two sets of shock absorbers 28 are installed on one side of the fixed rod 21. These shock absorbers 28 act as a buffer when the traveling mechanism 2 encounters obstacles and generates vibrations, protecting the entire device, including the detection device 44, from damage and ensuring the continuity and accuracy of the detection process.

[0033] refer to Figure 4 and Figure 5 A turntable 4 is rotatably provided on the upper side of the base 1. The turntable 4 is driven by a motor to drive the detection mechanism fixed on the upper end to rotate. The detection mechanism includes a hollow sleeve 41 fixed on the upper side of the turntable 4. An adjusting rod 43 is slidably provided in the hollow sleeve 41. A detection device 44 is installed on the upper end of the adjusting rod 43. The detection device 44 uses a thermal imaging camera to identify potential hot spots by detecting temperature changes at electrical connection points, and discover problems that may cause fires or equipment failures in advance. A screw rod 46 is rotatably provided inside the hollow sleeve 41. The screw rod 46 is driven by a motor and is threadedly connected to the adjusting rod 43. When the screw rod 46 is driven by the motor, the adjusting rod 43 can automatically slide in the hollow sleeve 41 to adjust the height of the detection device 44 to meet the detection requirements of electrical equipment at different heights.

[0034] Additionally, limit slots are provided on both sides of the hollow sleeve 41. These slots provide sliding tracks for the limiter 47, ensuring that the adjustment rod 43 maintains linear motion during height adjustment, preventing deviation or shaking. The limiter 47 is fixed to the bottom of the adjustment rod 43 and consists of a circular plate in the middle and long plates extending from either side. This design allows the limiter 47 to be securely attached to the adjustment rod 43 while also tightly fitting into the limit slots through the long plates at either end. As the adjustment rod 43 moves up and down, the limiter 47 also slides within the limit slots, ensuring that the vertical motion path of the adjustment rod 43 remains consistent. To further enhance the stability of the limiter 47, side rods 42 are provided on the upper side of the turntable 4. The ends of the limiter 47 and the side rods 42 are designed to slide together. This means that as the adjustment rod 43, carrying the limiter 47, moves up and down along the screw rod 46 within the hollow sleeve 41, the limiter 47 also slides along the side rods 42, providing additional support and guidance. Such a double protection mechanism greatly improves the horizontal stability and accuracy of the adjustment rod 43 during movement, prevents any possible tilting or swinging, and ensures that the detection device 44 is always in the best working position.

[0035] The walking path of the traveling mechanism 2 is adjusted according to the detection direction after the detection mechanism rotates, so that the detection mechanism and the traveling mechanism 2 complement each other to complete the safety detection of the electrical equipment.

[0036] The upper side of the detection device 44 is protected by a protective cover 45. In some working scenarios where there may be a risk of collision, the protective cover 45 provides an additional buffer layer, reducing the risk of damage to the detection device 44 caused by accidental collisions, and ensuring the safety of operation and the integrity of the equipment.

[0037] An outer ring 5 is fixedly connected to the outside of the turntable 4, and an obstacle removal mechanism is installed on one side of the outer ring 5. Sensors 3 are installed on all four sides of the base 1. The sensors 3 are used to detect whether there is an obstacle at the front end of the walking path. When there is an obstacle, the obstacle can be removed by the obstacle removal mechanism.

[0038] refer to Figure 6 and Figure 7The obstacle-clearing mechanism comprises a pair of levers 51 rotatably mounted on the upper side of the outer ring 5. A certain clearance between the bottom of the levers 51 and the ground is intentionally maintained during design. This design does not affect the overall mobility of the device while effectively removing small obstacles on the ground. The levers 51's primary function is to detect an obstacle ahead and, by rotating outward, push the obstacle to the sides of the device, clearing a path for further movement. Each lever 51 is fixedly connected to a bevel gear 3 54, while a rotating lever 2 55 is rotatably mounted on the outer ring 5. Bevel gear 4 56 is connected to each end of the rotating lever 2 55, and these two sets of bevel gear 4 56 mesh with two sets of bevel gear 3 54, respectively. This design ensures efficient force transmission, enabling the rotation of the rotating lever 2 55 to drive the two sets of bevel gear 4 56, which in turn drives the levers 51 outward. A first gear 57 is connected to the middle of the rotating lever 2 55. Furthermore, a second gear 58 driven by a motor is located on the upper side of the outer ring 5. When the first gear 57 and the second gear 58 are engaged, the motor drives the second gear 58 to rotate, which in turn causes the rotating rod 2 55 to rotate with the two sets of bevel gears 4 56 through the first gear 57, and finally causes the shifting rod 51 to rotate outward and push the obstacle.

[0039] Furthermore, to enhance the functionality and safety of the obstacle-clearing mechanism, an outer plate 52 is hingedly attached to the end of the lever 51 and equipped with an elastic member 53. This design not only improves obstacle-clearing effectiveness but also provides an additional protection mechanism for the entire device. Each outer plate 52 is hingedly mounted to the end of the lever 51, allowing for appropriate tilt adjustment based on the shape and hardness of the obstacle encountered. An elastic member 53 is connected between the outer plate 52 and the lever 51. This arrangement allows the outer plate 52 to respond flexibly when contacting an obstacle and automatically return to its original position after the obstacle is cleared. The outer plate 52 is typically maintained in a slightly tilted position to more effectively contact and push against obstacles. The elastic member 53 provides the necessary cushioning force. When the outer plate 52 contacts an obstacle, it is compressed, reducing the impact on the outer plate 52 and the obstacle itself. Once the outer plate 52 has cleared the obstacle, the elastic member 53 forces it back to its original position, ensuring it is ready for the next obstacle.

[0040] In the absence of obstacles, the two sets of outer panels 52 are held in place by the elastic member 53, forming a protective barrier surrounding the device. This barrier not only helps to centrally guide the movement of the lever 51 but also prevents small particles or light obstacles from directly impacting the device, enhancing overall safety and durability.

[0041] refer to Figure 1 A top plate 6 is fixedly provided at the lower end of the side rod 42, and the top plate 6 shields a series of transmission mechanisms to prevent them from being affected by the external environment.

[0042] In summary: First, the walking mechanism 2 installed at the four corners on the lower side of the base 1 enables the equipment to move and turn flexibly, and adapt to operations in narrow spaces. The walking mechanism 2 includes a fixed rod 21, on which a rotating rod 24 and moving wheels 27 at both ends are provided. The motor drives the bevel gear 2 26 to engage with the bevel gear 1 25, causing the moving wheel 27 to rotate to achieve movement; at the same time, the cooperation between the gear plate 22 and the driving wheel 23 enables the entire walking mechanism 2 to accurately change direction. Secondly, a turntable 4 is provided above the base 1, on which a detection mechanism including a hollow sleeve 41, an adjustment rod 43 and a thermal imaging camera as a detection device 44 is installed. The screw rod 46 drives the motor to adjust the height of the adjustment rod 43 to meet the detection requirements of electrical equipment at different heights. The design of the limit slot and the side rod 42 ensures the stability of the adjustment rod 43 when it moves up and down. In addition, the protective cover 45 protects the detection equipment 44 from collision damage. The obstacle-clearing mechanism on outer ring 5 consists of a lever 51. When sensor 3 detects an obstacle ahead, the motor drives second gear 58, which, through a series of gears, rotates lever 51 outward to clear the obstacle. The hinged outer plate 52 and elastic member 53 at the end of lever 51 not only enhance the clearing effect but also form a protective barrier when there are no obstacles.
