Description

Technical Field

[0001] The utility model belongs to the technical field of traffic signal lamps, and in particular relates to a traffic signal lamp failure detection device. Background Art

[0002] Traffic lights are lights that direct traffic, usually consisting of red, green, and yellow lights. A red light means no passage, a green light means passage is allowed, and a yellow light means a warning.

[0003] However, due to various reasons, such as circuit failure or light source burnout, traffic lights may fail, causing the lights to go out. The extinction of traffic lights can cause traffic chaos at intersections or places with high traffic volume, which can easily lead to traffic accidents. It brings potential risks to traffic safety. Therefore, a reliable device is needed to detect the failure of traffic lights. Traffic light failure detection devices usually include sensors for detecting the brightness of the bulb. The sensor should be installed near the bulb or LED unit of each signal light, which can be close to the inner side of the sunshade.

[0004] However, the existing sensors are troublesome to install and can only be installed on signal lights of fixed models, thereby reducing the scope of application of the device. Utility Model Content

[0005] The utility model provides a traffic signal lamp failure detection device, aiming to solve the problem that the sensor is troublesome to install and can only be installed on a signal lamp of a fixed model, thereby reducing the application range of the device.

[0006] The utility model is implemented in this way, comprising a transmission mechanism, a clamping mechanism and a photosensitive sensor;

[0007] The transmission mechanism includes a shell, a screw and a moving block, a first connecting plate and a second connecting plate. The screw extends into the shell and is rotatably connected to the shell. The moving block is threadedly connected to the screw. A limiting hole is provided on the shell. The first connecting plate is connected to the moving block. The first connecting plate extends out of the limiting hole and is slidably connected to the limiting hole. The second connecting plate is connected to the shell.

[0008] The clamping mechanism includes a first clamping plate, a second clamping plate and a clamping member; the first clamping plate is connected to the first connecting plate, the second clamping plate is connected to the second connecting plate, and the first clamping plate and the second clamping plate are respectively provided with two mounting grooves; the number of the clamping members is four, and the four clamping members are respectively arranged in the mounting grooves; an arc-shaped protrusion is arranged in the mounting groove, and a slide matching the arc-shaped protrusion is arranged on the clamping member, and the arc-shaped protrusion extends into the slide and can slide in the slide.

[0009] Optionally, the number of the first clamping plates and the number of the second clamping plates are both two.

[0010] Optionally, a base plate is installed under the shell, and the photosensor is arranged at the bottom end of the base plate.

[0011] Optionally, a slide groove is provided in the shell, a slider is slidably connected in the slide groove, and the slider is connected to the moving block.

[0012] Optionally, a ball bearing is provided on the sliding block.

[0013] Optionally, an anti-slip protrusion is provided on the clamping member.

[0014] Optionally, a rotating wheel is installed at the top of the screw.

[0015] The beneficial effect achieved by the utility model is that during actual use, the screw rotates in the first direction, driving the moving block to move downward, and at the same time, the first connecting plate moves downward, causing the first clamping plate to move downward, and when the clamping member contacts the sunshade, the slide and the arc-shaped protrusion allow the clamping member to rotate according to the curvature of the sunshade, ensuring that the clamping member and the sunshade fit tightly, and the traffic signal light failure detection device can be fixed in the sunshade, and the signal light failure can be detected by the photosensitive sensor; thereby, the traffic signal light failure detection device can be conveniently installed and can be installed on the sunshades of different signal lights, thereby improving the application range of the device.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

For example, a process, method, system, product or device that includes a series of steps, operations, components or modules is not limited to the listed steps, operations, components or modules, but may optionally include steps, operations, components or modules that are not listed, or may optionally include other steps, operations, components or modules that are inherent to these processes, methods, products or devices.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] like Figures 1 to 6 As shown, the traffic light failure detection device of the exemplary embodiment includes a transmission mechanism 1, a clamping mechanism 2 and a photosensitive sensor 3;

[0029] The transmission mechanism 1 includes a shell 11, a screw 12 and a moving block 13, a first connecting plate 15 and a second connecting plate 16. The screw 12 extends into the shell 11 and is rotatably connected to the shell 11. The moving block 13 is threadedly connected to the screw 12. A limiting hole 14 is provided on the shell 11. The first connecting plate 15 is connected to the moving block 13. The first connecting plate 15 extends out of the limiting hole 14 and is slidably connected to the limiting hole 14. The second connecting plate 16 is connected to the shell 11.

[0030] The clamping mechanism 2 includes a first clamping plate 21, a second clamping plate 22 and a clamping member 25; the first clamping plate 21 is connected to the first connecting plate 15, the second clamping plate 22 is connected to the second connecting plate 16, and the first clamping plate 21 and the second clamping plate 22 are respectively provided with two mounting grooves 23; the number of the clamping members 25 is four, and the four clamping members 25 are respectively arranged in the mounting grooves 23; an arc-shaped protrusion 24 is arranged in the mounting groove 23, and a slideway 26 matching the arc-shaped protrusion 24 is arranged on the clamping member 25, and the arc-shaped protrusion 24 extends into the slideway 26 and can slide in the slideway 26.

[0031] During the specific operation, during installation, the first clamping plate 21 and the second clamping plate 22 are located on the upper and lower sides of the sunshade, and the screw 12 is rotated in the first direction; at the same time, the moving block 13 is driven to move downward, prompting the first connecting plate 15 to drive the first clamping plate 21 to move downward, and when the clamping member 25 contacts the outer wall of the sunshade, according to the curvature of the sunshade, the clamping member 25 can be rotated through the slide 26 and the arc-shaped protrusion 24, prompting the clamping member 25 and the sunshade to maintain fit, so that the traffic light failure detection device can be fixed on the outer wall of the sunshade; through the above structure, it can be ensured that the installation is more convenient, time-saving and labor-saving, and the traffic light failure detection device can be installed on sunshades with different curvatures, thereby improving the application range of the device.

[0032] It is further explained that the photosensitive sensor 3 is an existing mature technology and is a device widely used to detect the intensity of light or the presence of light. The photosensitive sensor 3, also known as a photoresistor or a photodiode, uses the energy of light to measure the intensity of light. Their working principle is based on the photoelectric effect of photosensitive elements, and they are usually made of semiconductor materials such as silicon or germanium. When the light is weakened, the conductivity decreases and the resistance increases. The change in this resistance value can be used to detect the intensity of light; and the photosensitive sensor 3 is usually connected to a circuit, such as a voltage divider circuit, to measure the change in resistance value and convert it into a voltage signal output. This voltage signal can be further processed by a microcontroller or other electronic device; the working principle of the photosensitive sensor 3 is a technical means well known to those skilled in the art, and will not be described in detail here.

[0033] When the traffic light failure detection device is installed, the photosensitive sensor 3 is located at the top of the sunshade, so that the photosensitive sensor 3 can detect the light source of the traffic light; and because the photosensitive sensor 3 is located at the top of the inner side of the sunshade, the positions of vehicles and pedestrians are lower, and therefore, vehicles and pedestrians look at the traffic light diagonally upward, so the photosensitive sensor 3 will not affect the vehicles or pedestrians from viewing the traffic light.

[0034] As an optional implementation, the number of the first clamping plates 21 and the number of the second clamping plates 22 are both two.

[0035] By providing two first clamping plates 21 and a second clamping plate 22, the overall fixing effect of the traffic light failure detection device can be improved, and the presence of multiple clamping plates can provide redundancy. Even if one of the clamping plates has a problem, the other clamping plates can still continue to provide support and fixation.

[0036] As an optional implementation, a bottom plate 4 is installed under the housing 11 , and the photosensor 3 is arranged at the bottom end of the bottom plate 4 .

[0037] The bottom plate 4 can be provided to protect the photosensitive sensor 3, to avoid rainwater from directly contacting the photosensitive sensor 3, and to avoid strong light from directly shining on the photosensitive sensor 3, thereby improving the detection accuracy of the photosensitive sensor 3 for traffic lights.

[0038] As an optional implementation, a slide groove 5 is opened in the housing 11 , a slider 6 is slidably connected in the slide groove 5 , and the slider 6 is connected to the moving block 13 .

[0039] The sliding connection between the slider 6 and the slide groove 5 can make the moving block 13 more stable when moving.

[0040] As an optional implementation, a ball 7 is provided on the slider 6 .

[0041] The provision of the ball bearings 7 can make the slide block 6 slide more smoothly in the slide groove 5 .

[0042] As an optional implementation, an anti-slip protrusion 8 is provided on the clamping member 25 .

[0043] The anti-slip protrusion 8 is made of rubber material, which can increase the friction force and ensure the stability of the clamping member 25 during clamping.

[0044] As an optional implementation, a rotating wheel 9 is installed at the top of the screw rod 12 .

[0045] The screw rod 12 can be conveniently rotated by the rotating wheel 9 .

[0046] Therefore, through the above technical solution, the traffic signal light failure detection device can be easily installed and can be installed in different traffic signal light sunshades, thereby improving the application scope of the device.

[0047] The exemplary embodiments of the present application may be combined with each other, and the exemplary embodiments obtained by the combination also fall within the scope of the present application.
