Description

Technical Field

[0001] This utility model relates to the field of substation monitoring technology, specifically a substation environmental monitoring device. Background Technology

[0002] With the rapid development of smart grids and unmanned substations, the safe and stable operation of substations increasingly relies on comprehensive environmental monitoring systems. Currently, substations typically use fixed-point surveillance cameras to monitor equipment and the surrounding environment daily. In routine inspections and accident analysis, it is often necessary to compare and analyze visible light video images with infrared thermal imaging data to accurately identify potential hazards such as equipment overheating and abnormal discharge. In practical applications, many substations use fixed monitoring equipment with limited coverage, making it difficult to comprehensively monitor the vast area of ​​the substation. During routine inspections, visible light cameras and infrared cameras cannot work independently to inspect different areas, thus reducing the coverage of the inspection. Utility Model Content

The fixed plate contacts... On the lower surface of the moving track, two driven sprocket shafts are installed on both sides of the fixed plate via bearings. One end of each driven sprocket shaft passes through the fixed plate and is welded to the inner cavity of the roller T-slot, connecting to two drive wheels. A moving drive assembly is installed below the fixed plate. A traction assembly connects the fixed plate to the drag chain T-slot. A rotation and steering assembly is installed below the moving drive assembly. Two pitch platform assemblies are installed below the rotation and steering assembly. One pitch platform assembly is connected to a visible light camera via screws, and the other pitch platform assembly is connected to an infrared camera via screws.

[0005] Preferably, the pulling assembly includes a pulling tube mounted on a fixed plate, the pulling tube passing through the neck of the T-slot of the cable chain, and a connecting block welded to the upper side wall of the pulling tube. The cable chain is fixedly connected to the side of the connecting block, and the cable chain is placed on the shoulders of the T-slot of the cable chain on both sides.

[0006] Preferably, the mobile drive assembly includes two sprocket mounting blocks welded to the lower surface of a fixed plate. A dual-output shaft motor is bolted between the two sprocket mounting blocks on the lower surface of the fixed plate. Two drive sprocket shafts are mounted on the opposite sides of the two sprocket mounting blocks via bearings. The two drive sprocket shafts pass through the sprocket mounting blocks and are connected to the two corresponding output shafts of the dual-output shaft motor via couplings. Chains are connected to the sprocket portions of the two drive sprocket shafts and the sprocket portions of the corresponding two driven sprocket shafts.

[0007] Preferably, the rotary steering assembly includes two sprocket mounting blocks with mounting plates welded to their undersides. A worm gear shaft is mounted on the underside of the mounting plates via bearings. Two worm mounting blocks are welded to the underside of the mounting plates. A first worm is mounted between the two worm mounting blocks via bearings.

A steering plate is welded to the underside of the worm gear shaft. Two support gears are mounted on the lower surface of the steering plate via bearings, and the two support gears mesh with each other. A motor mounting bracket is welded to the lower surface of the steering plate. A second motor is bolted to the lower surface of the motor mounting bracket. The output shaft of the second motor passes through the motor mounting bracket and a drive gear is mounted on its upper end via a flat key. The drive gear meshes with one support gear.

[0008] Preferably, the tilt platform assembly includes a support plate welded to the lower surface of the support gear. Two arc-shaped slide rails are welded to the underside of the support plate, and two corresponding slide rail grooves are formed on the two arc-shaped slide rails. A semi-worm gear is welded between the two arc-shaped slide rails under the support plate. A second worm fixing block is slidably connected to the two arc-shaped slide rails. Two fixing blocks are bolted to the second worm fixing block. The two fixing blocks slide through the two slide rail grooves and contact the upper surface of the arc-shaped slide rails.

Combined with the effective cable management of the traction assembly, this guarantees the reliability of the device's reciprocating movement over long distances, enabling continuous, blind-spot-free monitoring of the substation environment.

[0011] The monitoring field of view is flexibly adjustable in all directions: the rotary steering component uses a worm gear drive to drive the steering plate and the components below to rotate horizontally; the tilt platform component drives a half-worm gear through a second worm, causing the camera to tilt along an arc-shaped slide rail. The combination of these two movements enables the camera to adjust in multiple degrees of freedom in both the horizontal and vertical directions, greatly expanding the monitoring field of view.

[0012] Adaptable to various monitoring and analysis needs: The device is equipped with both a visible light camera and an infrared camera, which can separately collect visible light video and infrared thermal imaging data. In routine inspections and accident analysis, the two cameras can work together to provide directly comparable image data for condition diagnosis and fault analysis, effectively improving the comprehensive utilization value and diagnostic efficiency of monitoring data.

[0013] Stable transmission and reliable self-locking: Both rotation and pitch adjustment adopt worm gear mechanisms with self-locking characteristics, which can effectively resist external interference after the motor stops, and stably maintain the adjusted camera angle. This avoids the perspective shift caused by equipment vibration or wind, and ensures the continuous stability of the monitoring image perspective and the validity of the data.

[0024] Furthermore, the two drive wheels 13 have protrusions installed on their side walls, and the four rollers 9 have protrusion grooves on their side walls, with the protrusions meshing with the corresponding protrusion grooves.

[0025] Working principle: Mobile Inspection: Start the dual-output shaft motor 17, which drives the two drive sprocket shafts 15 to rotate via the coupling. The power is then transmitted to the driven sprocket shaft 14 via chain drive, thereby driving the drive wheels 13 on both sides to rotate within the roller T-slots 6. The drive wheels 13 engage with the protrusions and protrusion slots on the sidewalls of the rollers 9, driving the four rollers 9 to roll synchronously along the moving track 1, thus enabling the entire device to move smoothly on the track.

[0026] Rotational Orientation: When it is necessary to adjust the horizontal direction of the monitoring device, the first motor 23 is started to drive the first worm gear 25 to rotate. The first worm gear 25 meshes with the worm wheel on the worm wheel shaft 19, causing the worm wheel shaft 19 and the steering plate 20 below it to rotate in the horizontal plane, thereby aligning the monitoring device with the target location.

[0027] Angle and Pitch Adjustment: This device achieves precise control of the monitoring angle through two-stage adjustment. First, the second motor 24 is activated to drive the drive gear 26 to rotate, which in turn drives a meshing support gear 34 to rotate. Since the two support gears 34 mesh with each other, this movement will synchronously cause the two support gears 34 to deflect in opposite directions at the same angle, thereby adjusting the relative angle between the two support plates 27 and their pitch platform components. Based on this, the third motor 30 on the corresponding pitch platform component can be activated to drive the second worm gear 33 to rotate. The meshing movement of the second worm gear 33 and the half-worm wheel 29 pushes the second worm gear fixing block 31 to slide along the arc-shaped slide rail 28, thereby directly driving the visible light camera 7 or infrared camera 8 mounted on its lower surface to perform pitch movement.

[0028] Dual-camera collaboration: During inspection, the visible light camera 7 and the infrared camera 8 can work independently or synchronously. Through the above-mentioned movement, rotation, angle adjustment, and tilt adjustment, the spatial position, relative angle, and individual tilt angle of the two cameras can be flexibly adjusted, enabling them to scan a wide area of ​​the environment or coordinately align with specific equipment to simultaneously collect comparative data from visible light and infrared thermal imaging.
