Description

Technical Field

[0001] This invention relates to the field of traffic lane indicator technology, specifically an energy-saving tunnel traffic lane indicator. Background Technology

[0002] Tunnel lane indicators are essentially "intelligent traffic commanders" installed above the lanes inside tunnels. By displaying different symbols (such as green arrows and red crosses), they clearly and in real time inform each driver which lane is safe to pass through and which lane is closed due to an accident or construction. They are key devices for ensuring traffic safety in tunnels and preventing secondary accidents.

[0003] Lane indicators are installed inside tunnels to provide lane information. However, these indicators are susceptible to damage from strong winds, which can cause them to become unstable. When vehicles travel at high speeds inside the tunnel, the front of the vehicle compresses air, creating a positive pressure zone, while the rear creates a negative pressure zone. This pressure difference periodically impacts the indicator in the form of pulse waves, and the strong winds directly impact the indicator surface, making it easy for the indicator to fall off over time.

[0004] Therefore, this invention proposes an energy-saving tunnel traffic lane indicator to solve the aforementioned problems. Summary of the Invention

[0020] This invention provides the following technical solutions: Example

[0021] Please see Figures 1-8 An energy-saving tunnel traffic lane indicator includes a main body 1. A mounting rod 2 is fixedly connected to the upper side of the main body 1, and a mounting plate 3 is fixedly connected to the upper end of the mounting rod 2. A base plate 4 is fixedly connected to the lower side of the main body 1. A windbreak unit 6 is provided on the upper side of the base plate 4. The windbreak unit 6 includes a guide plate 61, which is fixedly connected to the upper side of the base plate 4. Two guide blocks 62 are slidably connected to the outer side of the guide plate 61. A vertical plate 63 is fixedly connected to the upper side of the guide block 62. A mounting block 64 is fixedly connected to the outer side of the vertical plate 63. Windbreak plates 65 are fixedly connected to the outer sides of both mounting blocks 64. A transparent window 66 is provided in the middle of the windbreak plate 65. A fixed cover 7 is fixedly connected to the upper side of the base plate 4. A top plate 9 is fixedly connected to the upper side of the fixed cover 7. Multiple ventilation holes 8 are provided on the outer side of the fixed cover 7. The fixed cover 7 is used to protect the main body 1, and the multiple ventilation holes 8 are used to facilitate the heat dissipation of the indicator. The mounting plate 3 is installed together with the tunnel.

[0022] The wind deflector 65 has an arc-shaped structure. An inclined plate 68 is rotatably connected to the upper side of both wind deflectors 65. A rotating block 634 is rotatably connected to the outer side of the inclined plate 68. A moving block 69 is fixedly connected to the outer side of the rotating block 634. A base block 612 is fixedly connected to the lower side of the moving block 69. A sliding rod 613 is fixedly connected to the rear side of the main body 1. A protective cylinder 615 is fixedly connected to the upper side of the main body 1. A rotating rod 616 is rotatably connected to the inner side of the protective cylinder 615. A take-up roller 617 is fixedly connected to the outer side of the rotating rod 616. A connecting rope 611 is wound around the outer side of the take-up roller 617. A top block 610 is fixedly connected to the upper side of the movable block 69. A connecting rope 611 is fixedly connected to the top block 610. The upper end of the rotating rod 616 passes through the upper side of the protective cylinder 615 and is fixedly connected to the fan blade 618. The connecting rope 611 is slidably connected to the protective cylinder 615. A baffle 619 is fixedly connected to the upper side of the protective cylinder 615. A sliding rod 613 is slidably connected to the bottom block 612. A spring 614 is fixedly connected between the bottom block 612 and the main body 1. The inclined plates 68 on both sides are symmetrically arranged. The guide plate 61 has an arc-shaped structure. Two reflectors are fixedly connected to the outer side of the wind deflector 65. Plate 67, two reflectors 67 are located on the upper and lower sides of the transparent window 66, and inclined plate 68 is located above the main body 1. When the external environment is windy, the external airflow drives the fan blade 618 to rotate, the fan blade 618 drives the rotating rod 616 to rotate, the rotating rod 616 drives the take-up roller 617 to rotate, the take-up roller 617 drives the connecting rope 611 to retract, the connecting rope 611 drives the top block 610 to move, the top block 610 drives the moving block 69 to move, and the moving block 69 drives the inclined plate 68 to rotate. Because the two inclined plates 68 are symmetrically arranged, the inclined plates 68 drive the wind deflector 65 to rotate, and the two sides... The wind deflectors 65 are brought close together so that the wind deflectors 65 on both sides contact each other. The wind deflectors 65 are located in front of the main body 1, which facilitates the blocking of strong winds by the arc-shaped wind deflectors 65. Due to the arc-shaped structure, the airflow is dispersed to both sides of the main body 1, avoiding the strong airflow from affecting the stability of the main body 1 installation. When the wind force is less than the elastic force of the spring 614, the bottom block 612 is reset under the action of the spring 614, and the wind deflectors 65 on both sides move to the inside of the fixed cover 7. The transparent window 66 on the wind deflector 65 does not affect the display effect of the main body 1 while protecting the main body 1.

[0023] Multiple fixed pipes 620 are fixedly connected to the side of the wind deflector 65 near the main body 1. An arc-shaped pipe 621 is fixedly connected to the outside of each fixed pipe 620. Multiple cleaning heads 622 are fixedly connected to the outside of each arc-shaped pipe 621. There are two arc-shaped pipes 621, and a connecting pipe 623 is fixedly connected between the two arc-shaped pipes 621. A conveying chamber 625 is fixedly connected to the upper side of the top plate 9. A conveying pipe 624 is fixedly connected between the conveying chamber 625 and the connecting pipe 623. A partition plate 629 is fixedly connected to the inner side of the conveying chamber 625. A top pipe 626 is fixedly connected to the upper side of the conveying chamber 625. An output pipe 627 is fixedly connected to the front side of the main body 1, and an air inlet 628 is fixedly connected to the front end of the output pipe 627. The top pipe 626 is U-shaped. When the external environment is windy, the strong airflow passes through the air inlet 628 and enters the output pipe 627. The airflow is then distributed by the top pipe 626 and enters the conveying cavity 625. The airflow is then conveyed to the connecting pipe 623 through the conveying pipe 624. Under the action of the arc-shaped pipe 621, multiple cleaning heads 622 spray airflow onto the surface of the main body 1, which facilitates the cleaning of dust on the surface of the main body 1 when the baffle plate 65 moves, thus preventing dust from affecting the display effect of the main body 1.

A vertical plate 63 is fixedly connected to the upper side of the guide block 62. A mounting block 64 is fixedly connected to the outer side of the vertical plate 63. Windbreak plates 65 are fixedly connected to the outer sides of both mounting blocks 64. A transparent window 66 is provided in the middle of the windbreak plate 65. A fixed cover 7 is fixedly connected to the upper side of the base plate 4. A top plate 9 is fixedly connected to the upper side of the fixed cover 7. Multiple ventilation holes 8 are provided on the outer side of the fixed cover 7. The fixed cover 7 is used to protect the main body 1, and the multiple ventilation holes 8 are used to facilitate the heat dissipation of the indicator. The mounting plate 3 is installed together with the tunnel.

A rotating block 634 is rotatably connected to the outer side of the inclined plate 68. A moving block 69 is fixedly connected to the outer side of the rotating block 634. A base block 612 is fixedly connected to the lower side of the moving block 69. A sliding rod 613 is fixedly connected to the rear side of the main body 1. A protective cylinder 615 is fixedly connected to the upper side of the main body 1. A rotating rod 616 is rotatably connected to the inner side of the protective cylinder 615.

A top block 610 is fixedly connected to the upper side of the movable block 69. A connecting rope 611 is fixedly connected to the top block 610. The upper end of the rotating rod 616 passes through the upper side of the protective cylinder 615 and is fixedly connected to the fan blade 618. The connecting rope 611 is slidably connected to the protective cylinder 615. A baffle 619 is fixedly connected to the upper side of the protective cylinder 615. A sliding rod 613 is slidably connected to the bottom block 612. A spring 614 is fixedly connected between the bottom block 612 and the main body 1. The inclined plates 68 on both sides are symmetrically arranged. The guide plate 61 has an arc-shaped structure. Two reflectors are fixedly connected to the outer side of the wind deflector 65. Plate 67, two reflectors 67 are located on the upper and lower sides of the transparent window 66, and inclined plate 68 is located above the main body 1. When the external environment is windy, the external airflow drives the fan blade 618 to rotate, the fan blade 618 drives the rotating rod 616 to rotate, the rotating rod 616 drives the take-up roller 617 to rotate, the take-up roller 617 drives the connecting rope 611 to retract, the connecting rope 611 drives the top block 610 to move, the top block 610 drives the moving block 69 to move, and the moving block 69 drives the inclined plate 68 to rotate. Because the two inclined plates 68 are symmetrically arranged, the inclined plates 68 drive the wind deflector 65 to rotate, and the two sides... The wind deflectors 65 are brought close together so that the wind deflectors 65 on both sides contact each other. The wind deflectors 65 are located in front of the main body 1, which facilitates the blocking of strong winds by the arc-shaped wind deflectors 65. Due to the arc-shaped structure, the airflow is dispersed to both sides of the main body 1, avoiding the strong airflow from affecting the stability of the main body 1 installation. When the wind force is less than the elastic force of the spring 614, the bottom block 612 is reset under the action of the spring 614, and the wind deflectors 65 on both sides move to the inside of the fixed cover 7. The transparent window 66 on the wind deflector 65 does not affect the display effect of the main body 1 while protecting the main body 1.

[0026] An airbag 5 is fixedly connected to the lower side of the base plate 4. An air cylinder 630 is fixedly connected to the rear end of the slide rod 613.

A stabilizing tube 633 is fixedly connected between the air cylinder 630 and the airbag 5. The conveying cavity 625 is U-shaped. The base block 612 drives the moving tube 632 to move. The moving tube 632 drives the piston ring 631 to move. The piston ring 631 pushes the gas in the air cylinder 630 out and through the stabilizing tube 633, so that the airbag 5 is inflated and expands, so that the airbag 5 can protect the lower part of the main body 1.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] During operation, when the external environment is windy, the external airflow drives the fan blades 618 to rotate. The fan blades 618 drive the rotating rod 616 to rotate, which in turn drives the take-up roller 617 to rotate. The take-up roller 617 then retracts the connecting rope 611, which in turn moves the moving block 69 on the top block 610. The moving block 69 then drives the inclined plate 68 to rotate, which in turn drives the wind deflector 65 to rotate. The wind deflectors 65 on both sides move closer together, making it easier for them to block and disperse the strong airflow, preventing the strong wind from affecting the stability of the main body 1. At the same time, the external airflow passes through the air inlet hopper 62. 8. The airflow is delivered to the delivery chamber 625 and passes through the delivery pipe 624, connecting pipe 623 and arc-shaped pipe 621, so that multiple cleaning heads 622 spray airflow onto the surface of the main body 1, which facilitates the cleaning of dust on the surface of the main body 1 (the airflow intensity is weakened by the buffer between the delivery chamber 625 and the air inlet 628, so as not to affect the stability of the main body 1 installation). At the same time, the bottom block 612 drives the piston ring 631 on the moving pipe 632 to move, so that the gas in the air cylinder 630 is pushed out, and through the stabilizing pipe 633, the air bag 5 is inflated, which facilitates the protection of the bottom of the main body 1.
