Description

Technical Field

[0001] This invention relates to the field of highway equipment technology, specifically to a device and method for preventing environmental risks in ecologically sensitive areas of highways. Background Technology

[0002] As linear engineering projects, highways commonly traverse various environmentally sensitive areas such as nature reserves, forest parks, and water source protection areas. Despite prior feasibility studies and approvals, the risk of environmental incidents in these sensitive sections remains unavoidable. Currently, highways generally use signs to warn drivers to drive cautiously when entering protected areas. However, these signs suffer from problems such as insufficient visibility, unclear indication of sensitive sections, and limited effectiveness. Furthermore, highways generate significant dust during vehicle traffic, and conventional luminous signs accumulate dust over time, affecting their illumination and warning effectiveness. Therefore, we propose an environmental risk prevention device and method for highways in ecologically sensitive areas to address these issues. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Example 1: Refer to Figure 1 , 2 This is the first embodiment of the present invention, which provides an environmental risk prevention device and method for ecologically sensitive areas of highways. It includes a mounting plate 1, a support column 2 fixedly connected to the top of the mounting plate 1, a fixing plate 3 fixedly connected to the top of the support column 2, a support frame 4 fixedly connected to one side of the top of the fixing plate 3, a warning sign 5 fixedly connected to one side of the top of the support frame 4, a cleaning transmission assembly 6 coaxially rotatably mounted on the warning sign 5, a scraper 7 fixedly connected to one end of the cleaning transmission assembly 6, and one side of the scraper 7 slidably connected to the surface of the warning sign 5; a luminous warning slogan is pre-embedded on the front of the warning sign 5, and an acrylic sheet is used to protect the luminous warning slogan; a lithium battery and controller are pre-built inside the support column 2. The pre-buried piles beside the highway fix the mounting plate 1 vertically to the ground. The support column 2 supports the fixing plate 3 to the predetermined appropriate height. The solar panel 8 converts solar energy into electrical energy. Part of the converted electrical energy is stored in the lithium battery, and the other part powers the luminous warning sign and the dual-output shaft motor 9. After the controller controls the luminous warning sign to be powered, it emits light to warn passing vehicles on the highway at night or in poor lighting conditions. The controller controls the dual-output shaft motor 9 to work intermittently according to the predetermined program. Through the transmission shaft 10 at one end, it drives the cleaning transmission component 6 to work. The cleaning transmission component 6 drives the scraper 7 to clean the surface of the warning sign 5 to avoid excessive dust accumulation, which would affect the warning effect. A dual-output shaft motor 9 is fixedly connected to the top of the fixed plate 3. Drive shafts 10 are fixedly connected to both ends of the dual-output shaft motor 9. One drive shaft 10, away from the dual-output shaft motor 9, is fixedly connected to a cleaning transmission assembly 6. The other drive shaft 10, away from the dual-output shaft motor 9, is connected to an angle adjustment assembly 11. The top of the angle adjustment assembly 11 is rotatably connected to one side of the bottom of the solar panel 8. A fixing rod 12 is rotatably connected to the center of the bottom of the solar panel 8. The bottom end of the fixing rod 12 is fixedly connected to the other side of the top of the fixed plate 3. When the dual-output shaft motor 9 operates intermittently, it drives the angle adjustment assembly 11 to rise and fall via the other drive shaft 10, thereby changing the orientation of the solar panel 8 so that the solar panel 8 can always face the direct sunlight, increasing the utilization rate of solar energy.

[0016] Example 2: Refer to Figure 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the cleaning transmission assembly 6 includes a transmission shaft 62. One side of the transmission shaft 62 is rotatably sleeved on the top of the support frame 4 and the end is fixedly connected to the scraper 7. The other side of the transmission shaft 62 is fixedly sleeved with a linkage shaft 61. One end of a toggle rod 66 is slidably connected to the outer wall of the linkage shaft 61. The other end of the toggle rod 66 is fixedly connected to a mounting cylinder 63. The transmission shaft 10 is fixedly sleeved inside the mounting cylinder 63. One end of a connecting rod 64 is fixedly connected to the two end faces of the mounting cylinder 63 that are perpendicular to the toggle rod 66. The other end of the connecting rod 64 is fixedly connected to an arc-shaped strip 65. The arc-shaped strip 65 is provided to ensure the tightness of the connection between the linkage shaft 61 and the toggle rod 66, to prevent the toggle rod 66 from disengaging from the linkage shaft 61, and to avoid misalignment between the toggle rod 66 and the arc-shaped groove.

[0017] Specifically, there are two opposing toggle levers 66, both of which are cylindrical structures. Limiting rings 611 are fixedly connected to the edges of both ends of the linkage shaft 61. The two ends of the two limiting rings 611 are respectively provided with a first recess 613, a second recess 614, a third recess 615, and a fourth recess. The arc-shaped surface on one side of the linkage shaft 61 is respectively provided with a first arc-shaped groove 612 and a second arc-shaped groove 616. The first arc-shaped groove 612 and the second arc-shaped groove 616 are cross-connected at the middle of the linkage shaft 61. The toggle lever 66 is slidably connected in the first arc-shaped groove 612 or the second arc-shaped groove 616. The arc-shaped strip 65 is slidably connected in the first recess 613, the second recess 614, the third recess 615, or the fourth recess.

[0018] Specifically, the first recess 613 and the second recess 614 are connected by the first arc-shaped groove 612, and the third recess 615 and the fourth recess are connected by the second arc-shaped groove 616. The rotating mounting cylinder 63 causes the arc-shaped strip 65 to slide out of the third recess 615. Then, a lever 66 slides from the first recess 613 into the first arc-shaped groove 612. With the continuous rotation of the mounting cylinder 63, the lever 66 slides into the second recess 614 through the first arc-shaped groove 612. At this time, another arc-shaped strip 65 is about to slide into the fourth recess, and simultaneously, the linkage shaft 61 rotates 180 degrees, thereby driving the fixedly connected transmission shaft 62 to rotate.

[0019] Specifically, a limiting slide bar 82 is fixedly connected to one side of the bottom of the solar panel 8, and a sliding seat 83 is slidably connected inside the limiting slide bar 82. The sliding connection between the sliding seat 83 and the limiting slide bar 82 increases the range of rotation angle of the solar panel 8. An angle adjustment component 11 is rotatably connected to the bottom of the sliding seat 83. A mounting base 81 is fixedly connected to the center of the bottom of the solar panel 8, and a fixing rod 12 is rotatably connected to the bottom of the mounting base 81. The rotatable connection between the fixing rod 12 and the mounting base 81 ensures that the solar panel 8 can rotate smoothly.

[0020] Specifically, the angle adjustment assembly 11 includes a housing 111, which is fixedly connected to the top of the fixed plate 3. One side of the housing 111 is rotatably connected to one end of the transmission shaft 10, and the end of the transmission shaft 10 is fixedly connected to a driving bevel gear 112. The bottom of the driving bevel gear 112 is meshed with a driven bevel gear 113. An internally threaded sleeve 114 is fixedly sleeved inside the driven bevel gear 113. The top of the internally threaded sleeve 114 is rotatably mounted on the top of the housing 111. A threaded rod 115 is rotatably sleeved inside the internally threaded sleeve 114 through a threaded structure. A connecting seat 116 is fixedly connected to the top of the threaded rod 115, and a sliding seat 83 is rotatably connected to the top of the connecting seat 116. When the angle adjustment component 11 is working, it drives the internal threaded sleeve 114 to rotate through the meshing transmission of the active bevel gear 112 and the driven bevel gear 113. When the internal threaded sleeve 114 rotates, it drives the threaded rod 115 to rise and fall linearly through the threaded structure. The threaded rod 115 is rotatably connected to the sliding seat 83 through the connecting seat 116. At the same time, the sliding seat 83 is slidably connected to the limiting slide bar 82, thereby changing the orientation of the solar panel 8 so that the solar panel 8 can always face the angle of direct sunlight, increasing the utilization rate of solar energy.

[0021] The present invention also provides a method for an environmental risk prevention device in an ecologically sensitive area of ​​a highway, comprising the following steps: Step 1: Embed luminous warning signs in advance on the front of warning sign 5, and cover the luminous warning signs with an acrylic sheet to protect them from damage caused by rain and snow. The support column 2 has a built-in lithium battery and controller. The controller controls the whole system, improving the overall intelligence level. The mounting plate 1 is fixed vertically on the ground by the pre-buried piles next to the highway. The support column 2 supports the fixing plate 3 to the predetermined appropriate height. Step 2: Solar panel 8 converts solar energy into electrical energy. Part of the converted electrical energy is stored in the lithium battery, and the other part powers the luminous warning sign and the dual-output shaft motor 9. After the controller controls the luminous warning sign to be powered, it emits light to warn passing vehicles on the highway at night or in poor lighting conditions. Step 3: The controller controls the dual output shaft motor 9 to work intermittently in forward and reverse directions according to the predetermined program. Through the transmission shaft 10 at one end, it drives the cleaning transmission component 6 to work. The cleaning transmission component 6 drives the scraper 7 to clean the acrylic plate covering the front of the warning sign 5 intermittently. The scraper 7 is made of transparent acrylic material to avoid obstructing the luminous warning sign. Step 4: After the dual-output shaft motor 9 operates intermittently, it drives the angle adjustment component 11 to rise and fall through the transmission shaft 10 at the other end, thereby driving the solar panel 8 to adjust the angle facing the sunlight.

[0022] Example 3: Reference Figure 1-5This is the third embodiment of the present invention. Based on the previous two embodiments, in use, a luminous warning sign is pre-embedded in the front of the warning sign 5, and an acrylic sheet is used to protect the luminous warning sign. A lithium battery and controller are pre-built inside the support column 2. The mounting plate 1 is vertically erected on the ground using pre-buried piles along the highway. The support column 2 supports the mounting plate 3 to a predetermined suitable height. The solar panel 8 converts solar energy into electrical energy. Part of the converted electrical energy is stored in the lithium battery, and the other part powers the luminous warning sign and the dual-output shaft motor 9. The controller controls the power supply to the luminous warning sign. The device emits a bright light to warn passing vehicles on the highway at night or in low-light conditions. The controller, according to a pre-programmed sequence, controls the dual-output shaft motor 9 to work intermittently. This motor, via a transmission shaft 10 at one end, drives the cleaning transmission assembly 6. When the cleaning transmission assembly 6 is working, the mounting cylinder 63 first rotates under the drive of the transmission shaft 10. This rotation causes the arc-shaped strip 65 to slide out of the third recess 615. Then, a toggle lever 66 slides from the first recess 613 into the first arc-shaped groove 612. With the continuous rotation of the mounting cylinder 63, the toggle lever 66 passes through the first arc-shaped groove 612. The inner slide enters the second recess 614, at which point another arc-shaped strip 65 will slide into the fourth recess. Simultaneously, the linkage shaft 61 rotates 180 degrees, thereby driving the fixedly connected transmission shaft 62 to rotate. The transmission shaft 62 drives the scraper 7 fixedly connected at the end to rotate 180 degrees. The scraper 7 cleans the acrylic sheet covering the front of the warning sign 5 to prevent excessive dust accumulation, which would affect the warning effect. When the dual output shaft motor 9 works in reverse, the mounting cylinder 63 rotates in reverse, and through the operation of the toggle lever 66, it drives the scraper 7 to clean the warning sign 5 in the reverse direction. After the dual output shaft motor 9 works intermittently... The angle adjustment component 11 is driven to rise and fall through the transmission shaft 10 at the other end. When the angle adjustment component 11 is working, it drives the internal threaded sleeve 114 to rotate through the meshing transmission of the active bevel gear 112 and the driven bevel gear 113. When the internal threaded sleeve 114 rotates, it drives the threaded rod 115 to rise and fall linearly through the threaded structure. The threaded rod 115 is rotatably connected to the sliding seat 83 through the connecting seat 116. At the same time, the sliding seat 83 is slidably connected to the limiting slide bar 82, thereby changing the orientation of the solar panel 8 so that the solar panel 8 can always face the angle of direct sunlight, thus increasing the utilization rate of solar energy.
