Description

Technical Field

[0001] This invention belongs to the technical field of road lighting equipment, and particularly relates to a street lamp. Background Technology

[0002] Streetlights are lighting fixtures that provide illumination to roads. They broadly refer to lighting fixtures within the road surface illumination range of traffic lighting. Streetlights are widely used in various places requiring illumination. In the transportation sector, streetlights are an indispensable and important component. However, most existing streetlights have simple structures and can only perform basic illumination tasks, failing to provide warnings for certain special situations, such as:

[0003] Road conditions are complex and unpredictable. On roads built along mountainsides or in valleys, rockfalls are common. These incidents are random and can occur due to various factors, and once they happen, they tend to last for a period of time. If a vehicle is caught in a sudden rockfall, a traffic accident is highly likely. Streetlights are typically installed in close proximity, and in the event of a rockfall, the falling rocks will inevitably strike the streetlights. Therefore, a streetlight that changes its color after being struck by a rockfall would effectively warn drivers in the distance, preventing them from driving towards the rockfall area and thus avoiding traffic accidents. Therefore, a streetlight capable of changing its color after being struck by a rockfall is needed to warn drivers in the distance. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a street light that can change its illumination color after being hit by a rolling stone, so as to warn drivers at a distance.

[0005] A street light includes a lamp post, an auxiliary rod fixedly connected to the lamp post, a lamp cover fixedly connected to the auxiliary rod, an arc-shaped transparent glass fixedly connected to the lamp cover, multiple lighting tubes fixedly connected inside the lamp cover, a sensing arc plate slidably connected to the lamp post, a sliding plate slidably connected to the auxiliary rod, one end of a hinge rod hinged to the sensing arc plate, the other end of a hinge rod hinged to the sliding plate, a movable plate slidably connected to the auxiliary rod, a mating sleeve fixedly connected to the movable plate, an arc-shaped red glass fixedly connected to the mating sleeve, and a first compression spring fixedly connected between the sensing arc plate and the lamp post.

[0006] It also includes a push plate fixed to the slide plate, a transmission head fixedly attached to it, a magnet fixedly attached to the auxiliary rod, the magnet being able to attract the transmission head, and a second compression spring fixedly attached between the auxiliary rod and the moving plate.

[0007] It also includes a baffle plate fixed to the additional rod.

[0008] The transmission head is slidably connected to the mating sleeve, and a third compression spring is fixed between the transmission head and the mating sleeve. A wooden block is fixed to the push plate, and the wooden block has two arc surfaces. The front end of the transmission head is a pointed shape with arc surfaces on both the top and bottom sides.

[0018] See Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 The diagram illustrates an embodiment of the present invention that can change the color of lighting to warn drivers at a distance when a rockfall occurs on the road. Further,

[0019] This street light includes a lamp post 101, an auxiliary rod 102 fixedly connected to the lamp post 101, a lamp cover 201 fixedly connected to the auxiliary rod 102, an arc-shaped transparent glass 202 fixedly connected to the lamp cover 201, multiple lighting tubes fixedly connected inside the lamp cover 201, a sensing arc plate 301 slidably connected to the lamp post 101, a sliding plate 401 slidably connected to the auxiliary rod 102, one end of a hinge rod 304 hinged to the sensing arc plate 301, the other end of the hinge rod 304 hinged to the sliding plate 401, a movable plate 603 slidably connected to the auxiliary rod 102, a mating sleeve 601 fixedly connected to the movable plate 603, an arc-shaped red glass 602 fixedly connected to the mating sleeve 601, and a first compression spring fixedly connected between the sensing arc plate 301 and the lamp post 101.

[0020] The lamp post 101 is installed in a section of road where stones are prone to fall, with the left side of the lamp post 101 facing the direction where large stones are likely to fall. When the lighting is working normally, the lighting tube inside the lamp cover 201 can be turned on, so that the light source can illuminate the nearby road through the curved transparent glass 202.

[0021] When a large rock falls and impacts the sensing arc plate 301 from the left side of the lamppost 101, the sensing arc plate 301 overcomes the elastic force of the first compression spring and slides to the right on the lamppost 101. This causes the sensing arc plate 301 to pull one end of the hinge rod 304 to move synchronously with the sensing arc plate 301. The other end of the hinge rod 304 then pushes the slide plate 401 upwards on the auxiliary rod 102. The slide plate 401 then pushes the mating sleeve 601 upwards, causing the curved red glass 602 on the mating sleeve 601 to move to a position where it meets the curved transparent glass. With the transparent glass 202 at the same vertical height, the light emitted by multiple lighting tubes passes through the curved transparent glass 202 and then through the curved red glass 602 to complete the illumination. This causes the light source color to change from the original white to a bright red. Consequently, when the sensing arc plate 301 is pushed by the rolling stone, the color of the light emitted by this device changes, thus achieving the effect of warning drivers at a distance. This allows drivers at a distance to accurately judge whether there is a rolling stone situation on the road section by the light source color when it is dark, thereby ensuring traffic safety.

[0022] See Figure 1 , Figure 6 , Figure 7 This diagram illustrates an embodiment of the present invention in which the curved red glass 602 automatically moves to the same vertical height position as the curved transparent glass 202 as the curved plate 301 slides. Further,

[0023] It also includes a push plate 402 fixed on the slide plate 401, a transmission head 605 fixed on the mating sleeve 601, a magnet 104 fixed on the auxiliary rod 102, the transmission head 605 is made of iron, the magnet 104 can attract the transmission head 605, and a second compression spring is fixed between the auxiliary rod 102 and the moving plate 603.

[0024] Under normal conditions, the transmission head 605 is at the same vertical height as the magnet 104. At this time, the transmission head 605 can contact and be attracted by the magnet 104. When the sensing arc plate 301 slides to the right, and then the hinge rod 304 drives the slide plate 401 to slide upward on the auxiliary rod 102, the push plate 402 can push the transmission head 605 to slide upward, thereby causing the transmission head 605 to gradually move relative to the magnet 104. When the transmission head 605 moves to a position where it is displaced from the magnet 104, the magnet 104 can no longer provide attraction for the transmission head 605. The force applied by the second spring causes the movable plate 603 to slide upwards. After the magnet 104 can no longer provide attraction to the transmission head 605, the upward sliding distance of the movable plate 603 is controlled only by the force of the second spring. As a result, provided that the sensing arc plate 301 does not slide out of the expected distance, as long as the sensing arc plate 301 slides, no matter how far the sensing arc plate 301 slides, the matching sleeve 601 will automatically move to the same vertical height position as the curved red glass 602 and the curved transparent glass 202, which facilitates changing the color of the light source and improves the subsequent warning effect.

[0025] See Figure 2 , Figure 6 The diagram illustrates an embodiment of the invention that further facilitates the automatic movement of the curved red glass 602 to the same vertical height position as the curved transparent glass 202. Further,

[0026] It also includes a baffle 103 fixed to the additional rod 102.

[0027] After the transmission head 605 moves to a position where it is misaligned with the magnet 104, and the magnet 104 can no longer provide an attractive force to the transmission head 605, the moving plate 603 will be subjected to the elastic force of the second compression spring, which will cause the moving plate 603 to continue to slide upward. When the moving plate 603 slides to contact the baffle 103 and abuts against the lower end of the baffle 103, the curved red glass 602 will be exactly at the same vertical height as the curved transparent glass 202, which will facilitate the subsequent task of changing the color of the light source to achieve the warning effect.

[0028] See Figure 7-8 This diagram illustrates an embodiment of the present invention that allows for automatic color changing of the light source even when a stone accidentally rolls from the right side of the sensing arc plate 301 and impacts it. Further,

[0029] The transmission head 605 is slidably connected to the mating sleeve 601. A third compression spring is fixed between the transmission head 605 and the mating sleeve 601. A wooden block 403 is fixed to the push plate 402. The wooden block 403 has two arc surfaces. The front end of the transmission head 605 is a pointed head with arc surfaces on both the top and bottom. Under normal conditions, the wooden block 403 is above the transmission head 605 and can contact the right surface of the magnet block 104.

[0030] Due to the complex and ever-changing outdoor conditions, the occurrence of rolling stones is not uniform. When installing the lamp post 101, only the left side of the lamp post 101 can be positioned in the direction most likely to cause a rolling stone to fall. If a rolling stone accidentally rolls from the right side of the sensing arc plate 301 and impacts it, the sensing arc plate 301 will overcome the elasticity of the first compression spring and slide to the left relative to the lamp post 101. At this time, the sliding plate 401 will slide downward on the auxiliary rod 102, causing the wooden block 403 to gradually press the transmission head 605 downward. When the transmission head 605 moves downward and is misaligned with the magnetic block 104, the magnetic block 104 can no longer provide an attractive force for the transmission head 605. The moving plate 603 will then be subject to the elasticity of the second compression spring and tend to slide upward. At this time, the wooden block 403 can... The transmission head 605 is positioned to make contact with the surface of the magnetic block 104 and to block the right side of the magnetic block 104. As the moving plate 603 continues to slide upward, the mating sleeve 601 will slide upward with the moving plate 603. During this process, the upper arc surface of the transmission head 605 will gradually contact the lower arc surface of the wooden block 403. Since the wooden block 403 is located between the transmission head 605 and the magnetic block 104, it can block the attraction force of the magnetic block 104. As a result, the transmission head 605 will be pressed by the wooden block 403 and gradually overcome the elastic force of the third compression spring to retract into the mating sleeve 601. Then, the transmission head 605 will gradually pass the position of the wooden block 403, so that the moving plate 603 can move smoothly to contact the baffle 103 and abut against the lower end of the baffle 103, and then complete the task of changing the color of the light source to achieve the warning effect.

[0031] By using the sliding mechanism of the transmission head 605 and the wooden block 403, the curved red glass 602 can still move to the same vertical height as the curved transparent glass 202 when the sensing arc plate 301 slides to the left, thus improving the warning effect.

[0032] See Figure 4-5 The diagram illustrates an embodiment of the invention that ensures the accuracy of warning operations. Further,

[0033] It also includes a slide block 501 slidably connected to the sensing arc plate 301. Two detection parts 502 are rotatably connected to the slide block 501. Each detection part 502 is fixedly connected to the slide block 501 with a torsion spring. Two angle sensors are fixedly connected to the slide block 501. The moving ends of the two angle sensors contact the two detection parts 502 respectively. A motor is fixedly connected to the sensing arc plate 301. A lead screw is fixedly connected to the output shaft of the motor. The lead screw is threadedly connected to the slide block 501. A pressure sensor is fixedly connected to the lower end of the baffle 103. The moving plate 603 can contact the pressure sensor.

[0034] When the sensing arc plate 301 is impacted and moved, causing the mating sleeve 601 to move to the same vertical height position as the curved red glass 602 and the curved transparent glass 202, the pressure sensor can receive the pressure from the moving plate 603, and then send a signal to operate the slide 501 to slide downwards. This causes the two detection parts 502 to gradually move downwards. If there is a rolling stone on the outside of the sensing arc plate 301 at this time, when the slide 501 moves to the point where one of the two detection parts 502 comes into contact with the rolling stone, as the slide 501 continues to slide downwards, the detection part 502 will gradually overcome the torsional force of the torsion spring and slide on the slide 501. Then, the signals received by the two angle sensors determine whether there is a rolling stone on the outside of the sensing arc plate 301, thereby ensuring the accuracy of the warning operation.

[0035] See Figure 6-8 This diagram illustrates an embodiment of the present invention in which the moving plate 603 automatically resets after detection by two detection units 502 and the discovery that no rolling stones are present on the outer side of the sensing arc plate 301. Further,

[0036] It also includes a pressure plate 105 that is slidably connected to the baffle 103, the pressure plate 105 being able to contact the movable plate 603, and an electric push rod that can drive the pressure plate 105 to slide is fixedly connected to the baffle 103.

[0037] After detection by the two angle sensors on the two detection units 502 and the slide block 501, if no rolling stones are found on the outer side of the sensing arc plate 301, the operating pressure plate 105 can slide downwards, causing the mating sleeve 601 to gradually slide downwards. This causes the mating sleeve 601 to press against the moving plate 603, overcoming the spring force of the second compression spring, and slide downwards, gradually resetting the moving plate 603. When the transmission head 605 moves to contact the wooden block 403, it will be gradually pressed by the arc surface on the upper side of the wooden block 403, causing the transmission head 605 to gradually retract into the mating sleeve. Inside the sleeve 601, the transmission head 605 passes smoothly again through the position of the wooden block 403. Since there are no rolling stones on the outside of the sensing arc plate 301, the sensing arc plate 301 can automatically reset to the position where it was not accidentally touched. At this time, the wooden block 403 is in a position offset from the magnetic block 104. Then, after the transmission head 605 passes smoothly through the position of the wooden block 403, it is pressed out again by the elastic force of the third compression spring, and then presses tightly against the right side surface of the magnetic block 104 and is attracted by the magnetic block 104 again. Then, the entire device is reset and can resume normal lighting work.

[0038] See Figure 7 The diagram illustrates an embodiment of the invention that facilitates periodic wiping of the outer surface of the curved transparent glass 202 to ensure long-lasting lighting effects. Further,

[0039] It also includes an annular cleaning brush 604 fixed to the movable plate 603.

[0040] When using this device for normal lighting operation, the pressing plate 105 can be slid down periodically, which in turn causes the pressing plate 105 to press the moving plate 603 down, causing the annular cleaning brush 604 to periodically pass over the location of the curved transparent glass 202, thereby periodically wiping the outer surface of the curved transparent glass 202 and ensuring long-lasting lighting effect.

[0041] See Figure 3-4 The diagram illustrates an embodiment that further enhances the warning effect according to the present invention.

[0042] Guide plates 303 are slidably connected to both the front and rear sides of the sensing arc plate 301, and a fourth compression spring is fixed between each guide plate 303 and the sensing arc plate 301.

[0043] If the rolling stone happens to be on one of the front or rear sides of the sensing arc plate 301, one of the two guide plates 303 will contact the stone and guide it, thus preventing the stone from being guided from one of the front or rear sides of the sensing arc plate 301 to another position. This also prevents the rolling stone from exerting force on the sensing arc plate 301 only in the front or rear direction, which could cause the sensing arc plate 301 to be unable to move normally. At the same time, since both guide plates 303 are slidably connected to the sensing arc plate 301, and each guide plate 303 is fixedly connected to the sensing arc plate 301 with a fourth compression spring, the two guide plates 303 can buffer the impact force in the front or rear direction, thus preventing the sensing arc plate 301 from being directly subjected to a large impact force in the front or rear direction, which could damage the equipment.

[0044] See Figure 4 A schematic diagram of an embodiment for avoiding a collision between a vehicle and the sensing arc plate 301 is shown. Further,

[0045] The sensing arc plate 301 is provided with multiple reflective strips 302.

[0046] When the lighting tube inside the lamp cover 201 malfunctions, the location of this device may not be obvious in dim light. At this time, when the headlights of passing vehicles shine on the sensing arc plate 301, multiple reflective strips 302 can reflect light, thereby enabling drivers in passing vehicles to accurately grasp the space occupied by the sensing arc plate 301, thus preventing vehicles from colliding with the sensing arc plate 301.

[0047] See Figure 9-10 A schematic diagram illustrating an embodiment that facilitates fixing the device is shown. Further,

[0048] The lamp post 101 has multiple fixing threaded holes at its bottom.

[0049] The entire device can be secured by screwing bolts into multiple threaded holes.
