Description

Technical Field

[0001] This application belongs to the field of traffic facility manufacturing technology, specifically a gradually decreasing height guardrail. Background Technology

[0002] Guardrails are primarily installed in the center of the road to separate it into lanes for different directions, ensuring orderly traffic flow. Because of their central location, they also prevent pedestrians from crossing the road illegally. However, some people still climb over the guardrails for their own convenience, which is extremely dangerous. Fortunately, society is generally civilized, so when pedestrians touch the guardrails and are reprimanded, they are often embarrassed and give up the idea of ​​climbing over, thus preventing many uncivilized behaviors. However, not every instance of someone climbing over the guardrail will result in a reprimand, nor will it always be seen.

[0003] Another issue is that the guardrails are typically 1.2 meters high at intersections where traffic congestion is concentrated. This design has drawbacks. According to statistics, a significant portion of traffic accidents on urban roads occur at intersections, and some of these accidents are related to the unreasonable or unscientific design of intersection facilities. This is because the guardrail height does not adequately consider the driver's seating height and potential blind spots for drivers and pedestrians. This makes it easy for drivers turning to be affected by the ends of the 1.2-meter guardrails (currently, the guardrails only affect the vision of drivers with lower chassis, not completely block it), preventing them from anticipating vehicles or pedestrians approaching from other intersections, thus leading to traffic accidents. Utility Model Content

[0004] This application addresses the shortcomings of existing technologies by designing a gradually decreasing guardrail with one end only 0.7m high and a sensor connected to a buzzer on its surface. This design ensures that the 0.7m end is placed at the end of the road, guaranteeing drivers a clear and unobstructed view. Furthermore, the buzzer and sensor provide timely warnings to pedestrians who may attempt to climb over the guardrail. This solves the problem that current guardrails, typically 1.2 meters high, can obstruct the view of vehicles turning or making U-turns at the end of the road and fail to promptly warn pedestrians against climbing over them.

[0005] The technical solution of this application is as follows:

[0006] A gradually decreasing height isolation fence includes a frame, one end of which is 1.2m high and the other end is 0.7m high. The upper section of the frame is provided with an anti-glare film, the middle and lower sections of the frame are provided with solar panels, a storage battery is provided inside the frame, a sensor is provided on the upper surface of the frame, and a buzzer is provided on the frame. The sensor and the buzzer are electrically connected to the storage battery, and the sensor signal is connected to the buzzer.

[0007] Preferably, the frame includes a first column, a second column, a first railing, a second railing, and a third railing. The first railing, the second railing, and the third railing are all located in the same plane. The first railing and the second railing are connected together by the first column. The first railing and the second railing are parallel, and the first column is parallel to the first railing. The second railing and the third railing are connected together by the second column. The third railing is parallel to the second railing, and the second column is parallel to the second railing. The storage battery is disposed in the first column and / or the second column. The height of the first railing is 0.7m, and the height of the third railing is 1.2m. The top of the second railing is an inclined surface. The relatively higher end of the top of the second railing is connected to the end of the third railing facing the second railing through the second column, and the relatively lower end of the top of the second railing is connected to the end of the first railing facing the second railing through the first column.

[0008] Preferably, the height of the first column is higher than the height of the first railing but lower than the height of the third railing, and the height of the second column is higher than the height of the third railing.

[0009] Preferably, the top ends of the first, second, and third barriers are each provided with a mounting groove along their length, and the sensor is installed in each of the mounting grooves. The top ends of the first, second, and third barriers are each provided with a top plate through the mounting groove. The top plate is fixedly connected to the bottom of the mounting groove by a spring. The side wall of the top plate is slidably connected to the side wall of the mounting groove. The length between the upper and lower ends of the top plate is greater than the depth of the mounting groove.

[0010] Preferably, the mounting groove is filled with sensors and springs in sequence along the length of the mounting groove, and one sensor is placed between any two springs.

[0011] Preferably, the lower end of the first column is provided with a first base, and the lower end of the second column is provided with a second base.

[0012] Preferably, the first column is also provided at the end of the first barrier away from the second barrier, and the second column is also provided at the end of the third barrier away from the second barrier.

[0013] Preferably, the first column has a mounting hole perpendicular to its axis, the second column has a mounting hole perpendicular to its axis, the left and right side frames of the first guardrail have first through holes, the left and right side frames of the second guardrail have second through holes, and the left and right side frames of the third guardrail have third through holes. A first bolt passes through the first through hole on the right side frame of the first guardrail, the mounting hole on the first column, and the second through hole on the left side frame of the second guardrail to lock the first guardrail and the second guardrail together. A second bolt passes through the second through hole on the right side frame of the second guardrail and the third through hole on the left side frame of the third guardrail to lock the second guardrail and the third guardrail together.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] This application designs a gradually decreasing guardrail by setting one end to only 0.7m high and having a sensor connected to a buzzer on its surface. This design ensures that the 0.7m end is placed at the end of the road to guarantee drivers a clear and unobstructed view. Furthermore, the buzzer and sensor can promptly alert pedestrians not to climb over the guardrail. This solves the problem that current guardrails, which are usually 1.2 meters high, can obstruct the view of vehicles when they need to turn or make a U-turn at the end of the road, and cannot promptly alert pedestrians not to climb over the guardrail.

[0020] like Figure 1-3As shown, a gradually decreasing height isolation fence includes a frame, one end of which is 1.2m high and the other end is 0.7m high. The upper section of the frame is provided with an anti-glare film 1, the middle and lower sections of the frame are provided with solar panels 2, the frame is provided with a storage battery, the upper surface of the frame is provided with a sensor 4, and the frame is provided with a buzzer 5. The sensor 4 and the buzzer 5 are both electrically connected to the storage battery, and the sensor 4 is signal-connected to the buzzer 5.

[0021] In this embodiment, with this design, the 0.7m end of the frame faces the end of the road, while the 1.2m end is in the middle of the road. This ensures that drivers' visibility is not obstructed by the guardrail (frame) when driving to the end of the road, as the frame is only 0.7 meters high at the end of the road, while the 1.2m height is not a problem in the middle section where vehicles do not need to turn. The solar panel 2 converts solar energy into electrical energy and stores it in a battery. The battery powers the buzzer 5 and sensor 4. When someone climbs over the frame, their hand touches the top of the frame, triggering sensor 4. The sensor then sends a signal to buzzer 4, which sounds an alarm. The alarm draws the attention of pedestrians to the climber, causing them to abandon their uncivilized behavior due to public pressure. This setup solves two technical problems simultaneously: one is that the frame affects the driver's view when turning when it is at the end of the road, and the other is how to eliminate or at least reduce the uncivilized behavior of climbing over the guardrail.

[0022] The specific structure of the frame includes a first upright 6, a second upright 7, a first railing 8, a second railing 9, and a third railing 10. The first railing 8, the second railing 9, and the third railing 10 are all located in the same plane. The first railing 8 and the second railing 9 are connected together by the first upright 6. The first railing 8 and the second railing 9 are parallel, and the first upright 6 is parallel to the first railing 8. The second railing 9 and the third railing 10 are connected together by the second upright 7. The third railing 10 is parallel to the second railing 9, and the second upright 7 is parallel to the second railing 9. The storage battery is located on the first upright. The first barrier 8 is housed within the first pillar 6 and / or the second pillar 7; that is, it can be installed within either the first pillar 6 or the second pillar 7. Alternatively, two or more storage batteries can be installed, meaning both the first pillar 6 and the second pillar 7 contain storage batteries. The height of the first barrier 8 is 0.7m, and the height of the third barrier 10 is 1.2m. The top of the second barrier 9 is sloping. The higher end of the top of the second barrier 9 is connected to the end of the third barrier 10 facing the second barrier 9 via the second pillar 7, and the lower end of the top of the second barrier 9 is connected to the end of the first barrier 8 facing the second barrier 9 via the first pillar 6. This arrangement of the first pillar 6 and the second pillar 7 facilitates the erection of the entire frame in the middle of the road. Simultaneously, the first pillar 6 and the second pillar 7 connect the first barrier 8, the second barrier 9, and the third barrier 10 into a single flat panel.

[0023] As a preferred embodiment, the height of the first post 6 is greater than the height of the first barrier 8 but less than the height of the third barrier 10. This facilitates the installation of the first barrier 8 between the two ends of one side of the first post 6, while ensuring that the lower end of the first barrier 8 does not contact the ground when the frame is erected in the center of the road, thus preventing sewage from soaking into the first barrier 8. The height of the second post 7 is greater than the height of the third barrier 10. The relationship between the second post 7 and the third barrier 10 is also as described.

[0024] As a preferred method, such as Figure 2As shown, the top ends of the first barrier 8, the second barrier 9, and the third barrier 10 are each provided with a mounting groove 11 along their length direction. Each mounting groove 11 contains a sensor 4. A top plate 12 is provided at the top ends of the first barrier 8, the second barrier 9, and the third barrier 10 through the mounting groove 11. The length of the top plate 12 at the top end of the first barrier 8 is equal to the length of the top end of the first barrier 8; the length of the top plate 12 at the top end of the second barrier 9 is equal to the length of the top end of the second barrier 9; and the length of the top plate 12 at the top end of the third barrier 10 is equal to the length of the top end of the third barrier 10. The top plate 12 is connected to the bottom of the mounting groove 11 by a spring 13. The sidewall of the top plate 12 is slidably connected to the sidewall of the mounting groove 11. The length between the upper and lower ends of the top plate 12 is greater than the depth of the mounting groove 11. With the mounting slot 11 in place, when someone climbs over it, an alarm will be triggered regardless of where they press on the upper surface of the first barrier 8, and similarly, an alarm will be triggered regardless of where they press on the upper surface of the second barrier 9. The design that the length of the top plate 12 at both ends is greater than the depth of the mounting slot 11 is to trigger the sensor located in the mounting slot 11 when the top plate 12 is pressed.

[0025] Preferably, the two side walls of the mounting groove 11 are provided with first protrusions 20 at the top opening of the mounting groove 11, and the top plate 12 is provided with second protrusions 21 on opposite sides, with the two second protrusions 21 facing away from the top plate 12 respectively. The distance between the two sides of the mounting groove 11 is greater than the gap between the second protrusions 20 on both sides of the mounting groove 11. The gap between the second protrusions 20 on both sides of the mounting groove 11 is greater than the thickness of the top plate 12. That is, the top plate 12 can move within the gap between the second protrusions 20 on both sides of the mounting groove 11. The through-hole setting of the mounting groove 11 facilitates the installation of the top plate 12, the spring 13, and the sensor 4. During installation, a mounting plate 19 can also be set up, and the spring 13 and the sensor can be installed on the mounting plate 19. Then, the mounting plate 19 is inserted into the mounting groove 11 from one end, so that the mounting plate 19 is located below the first protrusion 20. Then, the top plate 12 is inserted into the mounting groove 11 from one end, and the second protrusion 21 on the top plate 12 is located between the first protrusion 20 and the mounting plate 19. This allows the top plate 12 to be squeezed when it is pressed, which in turn squeezes the mounting plate 19 and then the sensor 4 (pressure sensor), thereby triggering the alarm system.

[0026] As a preferred method, such as Figure 3As shown, the mounting groove 11 is filled with sensors 4 and springs 13 sequentially along its length, with one sensor 4 positioned between any two springs 13. This arrangement of springs 13 ensures the product's service life as described in this application.

[0027] As a preferred embodiment, the lower end of the first column 6 is provided with a first base 14, and the lower end of the second column 7 is provided with a second base 15. The arrangement of the first base 14 and the second base 15 facilitates the installation of the frame in the center of the road.

[0028] As a preferred embodiment, the first column 6 is also provided at the end of the first barrier 8 away from the second barrier 9, and the second column 7 is also provided at the end of the third barrier 10 away from the second barrier 9. By providing multiple first columns 6 and second columns 7, the structure of this application is made more stable.

[0029] As a preferred embodiment, the first column 6 is provided with a mounting hole 16 perpendicular to the axis of the first column 6, the second column 7 is provided with a mounting hole perpendicular to the axis of the second column 7, the left and right end frames of the first guardrail 8 are provided with first through holes, the left and right end frames of the second guardrail 9 are provided with second through holes, and the left and right end frames of the third guardrail 10 are provided with third through holes. The first bolt 16 passes through the first through hole on the right side frame of the first guardrail 8, the mounting hole on the first column 6, and the second through hole on the left side frame of the second guardrail 9 to lock the first guardrail 8 and the second guardrail 9 together. The second bolt 17 passes through the second through hole on the right side frame of the second guardrail 9 and the third through hole on the left side frame of the third guardrail 10 to lock the second guardrail 9 and the third guardrail 10 together. With this setup, the first guardrail 8 and the second guardrail 9 are fixedly connected together by the first bolt 16, and the second guardrail 9 and the third guardrail 10 are fixedly connected together by the second bolt 17. At the same time, since it is a bolt locking method, it is more convenient to transport and disassemble the frame.
