Description

Technical Field

[0001] This invention relates to the field of power transmission channel protection and monitoring technology, specifically a three-dimensional visual positioning device for power transmission channel risks. Background Technology

[0002] A power transmission corridor is a spatial area in a power system consisting of high-voltage transmission lines and a surrounding protected corridor. It is a crucial component for transmitting electrical energy from power plants to load centers over long distances. Transmission lines can be classified into overhead transmission lines and underground cable lines according to their structure. Overhead transmission lines dominate ultra-high voltage and extra-high voltage power transmission due to their lower cost and ease of maintenance.

[0003] Because power transmission channels often stretch for hundreds or even thousands of kilometers, traversing complex geographical environments such as mountains, valleys, and forests, they are constantly exposed to natural disasters such as wildfires, icing, lightning strikes, and strong winds. They also face human-induced damage such as illegal construction, foreign objects snagging the lines, tree growth, and crane collisions with the lines. The operational risks are diverse and highly concealed, posing a constant and significant challenge to safe operation and maintenance. Many towers are equipped with visual micro-capture devices for all-weather image monitoring and foreign object identification. Various precision sensors are installed on the towers themselves to continuously monitor parameters such as conductor icing thickness, fitting temperature, sag, wind deflection, and tower tilt in real time. However, there are still areas for improvement in actual operation.

[0004] In areas prone to natural disasters such as sandstorms or acid rain, equipment exposed to the elements may be damaged during such events. To address this, protective covers are added to the outside of the equipment. Ventilation holes are created on the outside of these covers, and a glass plate is installed for monitoring devices to monitor the external environment. However, during sandstorms, visibility is low, reducing the significance of monitoring. Gravel may enter the protective cover through the ventilation holes, adhering to the outside of the monitoring equipment, affecting its heat dissipation and shortening its lifespan. Furthermore, high-speed moving gravel may impact and rub against the glass plate, potentially adhering to it or scratching it, affecting the clarity of the monitoring images from subsequent monitoring devices. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a three-dimensional visual positioning device for power transmission channel risks, which solves the problems in the prior art where gravel may enter the protective cover through heat dissipation holes, affecting the service life of the monitoring equipment and causing the glass plate to become less clear due to the impact of gravel.

[0006] The technical solution of this invention is as follows: A three-dimensional visual positioning device for power transmission channel risks includes a visual monitoring component with a protective shell on its outer side. The top and outer side of the protective shell are provided with ventilation holes for heat dissipation. A glass plate for the monitoring component to observe the outside world is embedded in the end of the protective shell. It also includes a protective mechanism to protect the visual monitoring component when it is idle. The protective mechanism includes a sealing plate, which is set around the ventilation holes. When idle, the sealing plate fits and seals the ventilation holes to prevent sand and other debris from entering the protective shell. The protective mechanism also includes two protective covers, symmetrically arranged around the glass plate. When not in use, the sealing plate moves the two protective covers together to prevent sand and other debris from damaging the glass plate.

[0007] Furthermore, multiple limiting posts are fixedly installed at the bottom of the sealing plate to limit the movement trajectory of the sealing plate. The limiting posts slide through the protective shell, and multiple return springs are fixedly installed between the sealing plate and the protective shell to maintain a distance between the sealing plate and the vent hole.

[0008] Furthermore, a rope is fixedly installed at the bottom of the sealing plate. The rope slides through the protective shell and pulls the sealing plate to seal the vent hole.

[0009] Furthermore, two sets of cooling fans are fixedly installed inside the protective shell. The cooling fans work in conjunction with the vents. The cooling fan at the top of the protective shell is an exhaust fan that discharges hot air from the protective shell, while the cooling fan on the side of the protective shell is an intake fan that blows outside air into the protective shell.

[0010] Furthermore, a temperature detection component is fixedly installed inside the protective shell, and the temperature detection component is electrically connected to the cooling fan.

[0011] Furthermore, the protective mechanism also includes an adjusting motor, which is fixedly installed inside the protective shell. A bidirectional lead screw is fixedly installed at the output end of the adjusting motor, and the end of the bidirectional lead screw is rotatably installed inside the protective shell. A winding shaft is fixedly installed on the outside of the bidirectional lead screw, and the two ropes are wound around the winding shaft on the same side.

[0012] Furthermore, the bidirectional lead screw has two sliders symmetrically threaded on its outer side. The bottom of the sliders is slidably engaged with a slide rail to limit the displacement trajectory of the sliders. The slide rail is fixedly installed inside the protective shell, and the sliders are fixedly connected to the protective cover.

[0013] Furthermore, a transmission bevel gear is fixedly installed on the outside of the bidirectional lead screw, a driven bevel gear is meshed on the outside of the transmission bevel gear, and a cleaning mechanism is installed on the outside of the driven bevel gear.

[0014] Furthermore, the cleaning mechanism includes a fixed column, which is rotatably installed through one side of the protective shell. The fixed column is fixedly connected to the driven bevel gear. A scraper is slidably installed on the inner side of the fixed column, and a scraper strip is fixedly installed on the outer side of the scraper for removing dirt from the outer side of the glass plate.

[0015] Furthermore, an elastic rope is fixedly installed between the scraper and the inner side of the fixed column, and an installation plate is fixedly installed on the outer side of the protective shell. Multiple vibration protrusions are fixedly installed on the outer side of the installation plate. When the scraper rotates, it passes through the vibration protrusions, causing undulating vibrations to remove dirt from the outer side of the scraper.

[0016] Furthermore, sealing strips to enhance sealing performance are fixedly installed on the opposite side of the two protective covers and at the bottom of the sealing plate.

[0017] The beneficial effects of this invention are as follows: When monitoring is suspended due to special weather conditions, the motor drive is adjusted to pull the sealing plate to seal the vent holes, preventing dirt such as sand or acid rain from entering the protective shell and reducing the possibility of decreased heat dissipation performance or damage to the monitoring components. Simultaneously, the bidirectional screw drives two sets of sliders and protective covers to move closer to each other, and the two protective covers are in contact to prevent dirt such as sand or acid rain from contacting the glass plate, thus extending the replacement cycle of the glass plate. A further improvement is that when the scraper rotates to the lower half-turn, it contacts the vibrating protrusion. With the assistance of the elastic rope, the scraper and scraper blade shake up and down, removing dirt from the outside of the scraper blade and improving the cleaning effect. Synchronously, the bidirectional lead screw drives the scraper and fixed column to rotate through the driven bevel gear and the transmission bevel gear, thereby causing the scraper to rotate and remove dirt from the outside of the glass plate, keeping the outside of the glass plate clean, improving the clarity of the image transmitted by the monitoring component, and reducing the probability of misjudgment.

Detailed Implementation

[0021] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0022] like Figure 1 , Figure 4 As shown, this embodiment of the invention provides a three-dimensional visual positioning device for power transmission channel risks, including a visual monitoring component with a protective shell 1 on its outer side. The protective shell 1 has ventilation holes 21 for heat dissipation on its top and outer side. A glass plate 4 for the monitoring component to observe the outside world is embedded in the end of the protective shell 1. It also includes a protective mechanism 2 for protecting the visual monitoring component when it is idle. The protective mechanism 2 includes a sealing plate 24, which is disposed around the ventilation holes 21.

[0023] In this embodiment, when not in use, the sealing plate 24 fits and seals the vent hole 21 to prevent sand and other debris from entering the protective shell 1.

[0024] Preferred, such as Figure 3 , Figure 4 As shown, two sets of cooling fans 215 are fixedly installed inside the protective shell 1, and a temperature detection component 5 is fixedly installed inside the protective shell 1. The temperature detection component 5 is electrically connected to the cooling fans 215. The cooling fans 215 are used in conjunction with the vent 21. The cooling fan 215 at the top of the protective shell 1 is an exhaust fan that discharges hot air from the protective shell 1, and the cooling fan 215 on the side of the protective shell 1 is an intake fan that blows outside air into the protective shell 1.

[0025] In this embodiment, the temperature detection component 5 detects the temperature inside the protective shell 1. When the temperature is within the natural heat dissipation threshold, the protective shell 1 relies on two sets of ventilation holes 21 for natural heat dissipation. When the temperature is within the single fan heat dissipation threshold range, the temperature detection component 5 controls the top cooling fan 215 to turn on through the data processor to assist the protective shell 1 in expelling hot air. When the temperature is higher than the single fan heat dissipation threshold, both sets of cooling fans 215 turn on simultaneously, blowing outside air into the protective shell 1 and expelling hot air from the protective shell 1 to accelerate heat dissipation.

[0026] Preferred, such as Figure 4 As shown, a plurality of limiting posts 22 are fixedly installed at the bottom of the sealing plate 24 to limit the movement trajectory of the sealing plate 24. The limiting posts 22 slide through the protective shell 1. A plurality of return springs 23 are fixedly installed between the sealing plate 24 and the protective shell 1 to maintain a distance between the sealing plate 24 and the vent hole 21.

[0027] Preferred, such as Figure 4 As shown, a rope 25 is fixedly installed at the bottom of the sealing plate 24. The rope 25 slides through the protective shell 1 and pulls the sealing plate 24 to seal the vent hole 21.

[0028] Preferred, such as Figure 3 As shown, the protective mechanism 2 also includes an adjusting motor 26, which is fixedly installed inside the protective shell 1. A bidirectional lead screw 27 is fixedly installed at the output end of the adjusting motor 26. The end of the bidirectional lead screw 27 is rotatably installed inside the protective shell 1. A winding shaft 210 is fixedly installed on the outside of the bidirectional lead screw 27. Two ropes 25 are wound around the winding shaft 210 on the same side.

[0029] In this embodiment, when monitoring is suspended due to special weather conditions, the adjusting motor 26 drives the bidirectional lead screw 27 and the winding shaft 210 to rotate. The winding shaft 210 tightens the rope 25, pulls the sealing plate 24 to fit and seal the vent hole 21, and the return spring 23 is compressed to prevent dirt such as sand or acid rain from entering the protective shell 1, thereby reducing the possibility of decreased heat dissipation performance or damage to the monitoring components.

[0030] Preferred, such as Figure 1 , Figure 2 As shown, the protective mechanism 2 also includes two protective covers 213, which are symmetrically arranged around the glass plate 4. On the opposite side of the two protective covers 213 and the bottom of the sealing plate 24, sealing strips 214 that improve sealing performance are fixedly provided. When idle, the sealing plate 24 drives the two protective covers 213 to stick together to prevent sand and other debris from damaging the glass plate 4.

[0031] Preferred, such as Figure 3As shown, the bidirectional lead screw 27 has two sliders 211 symmetrically threaded on its outer side. The bottom of the sliders 211 is slidably engaged with a slide rail 212, which is used to limit the displacement trajectory of the sliders 211. The slide rail 212 is fixedly installed inside the protective shell 1, and the sliders 211 are fixedly connected to the protective cover 213.

[0032] In this embodiment, the bidirectional lead screw 27 drives two sets of sliders 211 and protective covers 213 to move closer to each other. The two protective covers 213 fit together to prevent dirt such as sand or acid rain from contacting the glass plate 4, thus extending the replacement cycle of the glass plate 4.

[0033] Preferred, such as Figure 3 As shown, a transmission bevel gear 29 is fixedly installed on the outside of the bidirectional lead screw 27, a driven bevel gear 28 is meshed on the outside of the transmission bevel gear 29, and a cleaning mechanism 3 is installed on the outside of the driven bevel gear 28.

[0034] Preferred, such as Figure 5 As shown, the cleaning mechanism 3 includes a fixed column 33, which is rotatably installed through one side of the protective shell 1. The fixed column 33 is fixedly connected to the driven bevel gear 28. A scraper 31 is slidably installed on the inner side of the fixed column 33, and a scraper strip 32 is fixedly installed on the outer side of the scraper 31 for removing dirt from the outer side of the glass plate 4.

[0035] In this embodiment, the bidirectional lead screw 27 drives the scraper 31 and the fixed column 33 to rotate through the driven bevel gear 28 and the transmission bevel gear 29, thereby causing the scraper 32 to rotate to remove dirt from the outside of the glass plate 4, keeping the outside of the glass plate 4 clean, improving the clarity of the image transmitted by the monitoring component, and reducing the probability of misjudgment.

[0036] Preferred, such as Figure 6 As shown, an elastic rope 34 is fixedly installed between the scraper 31 and the inner side of the fixed column 33, and an installation plate 35 is fixedly installed on the outer side of the protective shell 1. Multiple vibration protrusions 36 are fixedly installed on the outer side of the installation plate 35. When the scraper 31 rotates, it passes through the vibration protrusions 36 and vibrates, removing dirt from the outer side of the scraper 32.

[0037] In this embodiment, when the scraper 31 rotates to the lower half-turn, it contacts the vibrating protrusion 36. With the assistance of the elastic rope 34, the scraper 31 and the scraper 32 shake up and down, removing dirt from the outside of the scraper 32 and improving the cleaning effect.

[0038] Specific working methods: Temperature detection component 5 detects the temperature inside the protective shell 1. If the temperature is within the natural heat dissipation threshold, the protective shell 1 relies on two sets of ventilation holes 21 for natural heat dissipation. If the temperature is within the single fan heat dissipation threshold range, the temperature detection component 5 controls the top cooling fan 215 to turn on via the data processor to assist the protective shell 1 in expelling hot air. If the temperature is higher than the single fan heat dissipation threshold, both sets of cooling fans 215 turn on simultaneously, blowing outside air into the protective shell 1 and expelling hot air from the protective shell 1 to accelerate heat dissipation.

[0039] When monitoring is suspended due to special weather conditions, the cooling fan 215 is turned off, the adjusting motor 26 drives the bidirectional lead screw 27 and the winding shaft 210 to rotate, the winding shaft 210 tightens the rope 25, pulls the sealing plate 24 to fit and seal the vent hole 21, and the return spring 23 is compressed to prevent dirt such as sand or acid rain from entering the protective shell 1, reducing the possibility of decreased heat dissipation performance or damage to the monitoring components. Synchronously, the bidirectional lead screw 27 drives two sets of sliders 211 and protective covers 213 to move closer to each other. The two protective covers 213 fit together to prevent dirt such as sand or acid rain from contacting the glass plate 4 and extend the replacement cycle of the glass plate 4. Synchronously, the bidirectional lead screw 27 drives the scraper 31 and the fixed column 33 to rotate through the driven bevel gear 28 and the transmission bevel gear 29, thereby causing the scraper 32 to rotate to remove dirt from the outside of the glass plate 4, keeping the outside of the glass plate 4 clean, improving the clarity of the image transmitted by the monitoring component, and reducing the probability of misjudgment. A further improvement is that when the scraper 31 rotates to the lower half-turn, it contacts the vibrating protrusion 36. With the assistance of the elastic rope 34, the scraper 31 and the scraper 32 vibrate up and down, removing dirt from the outside of the scraper 32 and improving the cleaning effect.

[0040] When monitoring is restored, the adjusting motor 26 rotates in the reverse direction, the winding shaft 210 unwinds the rope 25, the sealing plate 24 is reset under the elastic force of the reset spring 23, the two protective covers 213 move away from each other, and the glass plate 4 is exposed.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
