DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. The technical solutions of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0035] Reference Figures 1 to 12 This embodiment provides a self-powered monitoring device for transmission line safety warnings based on visual inspection, comprising a first block 1 and a second block 2. The first block 1 is located below the cable line, while the second block 2 is located above the cable line. Four fixing protrusions are symmetrically provided on the first block 1, and the second block 2 is provided with connecting grooves 12 for abutting and mating with the fixing protrusions. Connecting bolts are inserted through the side ends of the fixing protrusions, and the ends of the connecting bolts are threaded into the connecting grooves 12 of the second block 2 to securely connect the first block 1 and the second block 2. The arrangement of the first block 1 and the second block 2 facilitates installation and removal of the device, thereby facilitating maintenance and inspection of the device.

[0036] A push mechanism is provided between the first and second blocks 1, 2. This mechanism consists of four symmetrically arranged connecting blocks 8 and a push assembly resiliently connected to these blocks. The four blocks 8 are joined back-to-back in a cross-shaped pattern via a plug-in structure to form a cylindrical structure, through which the cables pass. A second mounting slot is defined within the inner wall of each connecting block 8, into which the push assembly is movably mounted.

[0037] Specifically, the plug-in structure includes a snap-in groove 20, a snap-in protrusion 21, a mounting hole 22, and a connecting block 23. A snap-in protrusion 21 is provided on one side of the upper surface of the splicing connecting block 8, and a snap-in groove 20 is provided on the other side of the upper surface of the splicing connecting block 8. When the upper and lower splicing connecting blocks 8 are spliced ​​together, the snap-in protrusion 21 cooperates with the snap-in groove 20 to secure them. The inner end surface of the splicing connecting block 8 is provided with a mounting hole 22 and a connecting block 23. The connecting block 23 is symmetrically provided with four sets of anti-slip inclined plates. When the left and right splicing connecting blocks 8 are spliced ​​together, they are plugged in and secured with the mounting holes 22 and the connecting block 23. The provision of the plug-in structure allows for better splicing and assembly of the splicing connecting blocks 8 and makes disassembly more convenient. It also reduces the number of device parts, thereby reducing processing costs.

[0038] Specifically, the push assembly consists of a support base 19 and a motorized wheel 30. The motorized wheel 30 is horizontally mounted on the support base 19. A second spring 29 is symmetrically mounted at the lower end of the support base 19, and the bottom end of the second spring 29 is fixedly connected to the inner bottom surface of the second mounting slot. Furthermore, the push assemblies on the inner sides of the four connecting blocks 8 are positioned in the four directions of the cable line, namely, the upper, lower, left, and right. The placement of the push assemblies allows the motorized wheel 30 to better compress the cable line, clamping it both vertically and horizontally, making the entire surveillance camera's movement on the cable line more stable.

[0039] A circular groove 18 for accommodating and installing the deflection detection mechanism is provided at the outer end of the splicing block 8. The inner walls of the first set of blocks 1 and the second set of blocks 2 are fitted with the outer wall of the splicing block 8. Correspondingly, a first installation groove 9 for installing the deflection detection mechanism is provided on the inner walls of the first set of blocks 1 and the second set of blocks 2. The deflection detection mechanism is fixed to the first set of blocks 1 and the second set of blocks 2 through the first installation groove 9, and the deflection detection mechanism is simultaneously located between the circular grooves 18 of the splicing block 8.

[0040] The deflection detection mechanism comprises a support rod 6, an abutment block 24, and a limit plate 28. One end of the support rod 6 is connected to the bottom surface of the abutment block 24, and the other end is connected to the top end of the limit plate 28. The top surface of the abutment block 24 is provided with an arcuate abutment groove, and several movable rollers 25 are equidistantly protruded from the arcuate abutment groove. The movable rollers 25 abut against the cable line. The arrangement of the abutment block 24 and the movable rollers 25 enables the bending and tension of the cable line to be checked while maintaining the sliding operation of the device. The lower end of the limit plate 28 is provided with a first spring 26. One end of the first spring 26 abuts and is fixed to the lower bottom surface of the limit plate 28. The other end of the first spring 26 is fixedly connected to a piezoresistive pressure sensor 27. The pressure sensor 27 is connected to the first mounting slot 9. In this embodiment, a deflection detection mechanism is connected between each of the four splicing blocks 8 and the cable line, so that the deflection detection mechanism is distributed above and below on both sides of the cable line. The model of the pressure sensor 27 is P3297. The pressure sensor 27 utilizes the piezoresistive effect. When the material is subjected to mechanical stress, its resistance value will change, and the magnitude of the pressure can be determined by measuring the change in the resistance value. Through the setting of the first spring 26 and the pressure sensor 27, the support rod 6 can be pushed so that the abutment block 24 can better fit the abutment line, and the reaction force can be transmitted to the pressure sensor 27 for inspection, thereby checking the tightness of the line.

[0041] Mounting base 3 has a connection base 31 at its base, on which a surveillance camera is mounted for monitoring the environment below the cable line. Four levels 4 are symmetrically positioned on the underside of mounting base 3, allowing the deflection position of the entire device to be checked. Mounting base 3 also houses a power supply for the various electrical components.

[0042] The second set of blocks 2 is provided with a solar power supply device, which is connected to the push assembly, deflection detection mechanism, and surveillance camera to provide power. The solar power supply device includes an exhibition panel 11, a first solar panel 15, and a second solar panel 35. Two exhibition panels 11 are symmetrically provided at the upper end of the outer wall of the second set of blocks 2. The outer wall of the second set of blocks 2 is provided with a storage slot for accommodating and mounting the two exhibition panels 11. The side ends of the exhibition panels 11 are each provided with a hinged protrusion 13, and the hinged protrusion 13 is provided with a fixed rotating rod. The second set of blocks 2 is provided with a connection hole 16 for movably connecting the fixed rotating rod. The inner side of each exhibition panel 11 is provided with a first solar panel 15, and the inner bottom surface of the storage slot of the second set of blocks 2 is provided with a second solar panel 35. When the exhibition panel 11 is opened, the device can be solar-charged through the first solar panel 15 and the second solar panel 35, which can better provide clean energy for the device, so that the device can maintain long-term operation without replacing batteries.

[0043] Several equidistantly spaced filter inlet holes 14 are provided on the outer wall of the display panel 11 for communicating with the inner cavity of the display panel 11. Filter inlet grooves 17 for communicating with the inner cavity of the second block 2 are symmetrically provided on both sides of the receiving slot of the second block 2. The lower ends of the filter inlet holes 14 and the filter inlet grooves 17 are both connected to the inner cavity of the second block 2. A quick connector 10 for communicating with the inner cavity of the second block 2 is provided on the first block 1. The inner cavities of the first block 1 and the second block 2 are connected by the quick connector 10. The model of the quick connector 10 is F-type DN15.

[0044] A mounting base 3 is provided at the lower end of the first block 1, and a water tank 34 is provided in the mounting base 3. A water pipe for communicating with the inner cavity of the first block 1 is provided at the upper end of the water tank 34. By setting the filtered water inlet hole 14 and the filtered water inlet groove 17, rainwater can be collected into the interior of the first block 1 through the quick connector 10 until it is conducted into the water tank 34 to replenish water in the water tank 34.

[0045] The outer layer of the surveillance camera is equipped with a hemispherical, transparent surveillance housing 5, which is fixed to a connecting base 31. The outer periphery of the connecting base 31 is provided with an annular slot 32 for accommodating a rotating cleaning block 7. The two ends of the rotating cleaning block 7 are pivotally connected within the slot 32 via a hinge shaft, which is connected to a micromotor. The top of the slot 32 is provided with a drainage groove 33, which is connected to a water tank 34. The inner side of the rotating cleaning block 7 is covered with absorbent cotton, which is attached to the surface of the surveillance housing 5. Driven by the micromotor, when the rotating cleaning block 7 rotates into the slot 32, it absorbs the water discharged from the drainage groove 33 and uses it to wipe and clean the surveillance housing 5.

[0046] The method for using the self-powered monitoring device for power transmission line safety warning based on visual detection described in this embodiment is as follows:

[0047] First, align the two upper splicing blocks 8 and the two lower splicing blocks 8 on the cable line through the snap-in grooves 20 and the snap-in protrusions 21, and then dock and fix the left and right splicing blocks 8 through the mounting holes 22 and the connecting blocks 23. Four sets of anti-slip bevel plates are provided on the connecting blocks 23. After the anti-slip bevel plates are inserted into the mounting holes 22, they will tilt and shrink, so that the anti-slip bevel plates can better abut the side walls of the mounting holes 22, thereby preventing the two sets of docked splicing blocks 8 from loosening.

[0048] Then, the first set of blocks 1 and the second set of blocks 2 are abutted against the outside of the splicing block 8, so that the fixing protrusions and the connecting grooves 12 are matched and abutted, and then the connecting bolts are inserted to fix the first set of blocks 1 and the second set of blocks 2. Then, the power supply and water tank 34 are installed inside the mounting base 3, so that the power supply is connected to components such as solar panels and motors through wires, and the installed water tank 34 is connected to the drainage groove 33 at the top of the card slot 32, so that the drainage groove 33 can release water droplets, which can then moisten the rotating cleaning block 7 for more effective cleaning of the monitoring shell cover 5.

[0049] After the device is installed, the deflection detection mechanism presses and fits the line through the first spring 26, and the pushing component presses and fits the cable line through the second spring 29. Then the device is started, and the electric wheel 30 on the pushing component rotates, thereby driving the device to slide on the line. The four electric wheels 30 on the upper, lower, left and right sides are staggered to clamp the cable line, so that the sliding operation of the device on the cable line is smoother. Through the arrangement of the first solar panel 15 and the second solar panel 35, the device can be better provided with energy, so that the device can maintain long-term operation without replacing the battery.

[0050] Then, due to the change in the operating position of the device, the line bends due to the influence of gravity. At this time, the abutment block 24 on the deflection detection mechanism is pushed under the bending deflection pressure of the line, causing the abutment block 24 on one side to rise and the abutment block 24 on the other side to fall. The bending state of the line is initially checked by the inspection value of the pressure sensor 27, and an auxiliary comparison check is performed through the four levels 4 at the bottom of the mounting base 3, so as to more accurately determine the bending state of the line; the tension of the transmission line is judged by the bending state of the line, and whether it is necessary to adjust and maintain this section of the line.

[0051] The surveillance camera monitors the lower area, thereby monitoring and detecting the ground area where the cable is installed, improving the cable line's ability to monitor and warn of the surrounding environment during operation. Long-term operation of the surveillance camera can cause dust to accumulate on the monitoring housing cover 5, affecting the normal operation of the surveillance camera. At this time, the rotary cleaning block 7 rotates and cooperates with the water discharged from the drainage drip groove 33 to clean the outer surface of the monitoring housing cover 5, allowing the surveillance camera to operate normally without being affected by dust. The provision of the filtered water inlet hole 14 and the filtered water inlet groove 17 can collect rainwater through the quick connector 10 and transfer the water to the interior of the first set of blocks 1, achieving self-supply cleaning.

[0052] The above content is a further detailed description of the present invention in combination with a specific preferred embodiment. It cannot be considered that the specific embodiments of the present invention are limited to this. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the present invention, which should be regarded as belonging to the scope of patent protection determined by the submitted claims of the present invention.
