DETAILED DESCRIPTION
[0029] The invention of this application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for illustration; based on the contents recorded in this application, other embodiments obtained without creative work are all within the scope of protection of the present invention.
[0030] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of clearly describing the present embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0031] like Figures 1 to 9 As shown, the embodiment of the present invention provides an environment-sensing warning smart street lamp, including a pole 1, a LED light source 2 is arranged on one side of the pole 1 for lighting, a control system 6 is arranged on the other side of the pole 1 for controlling the normal operation of the device, a light sensor 3 and a light collecting component 5 are arranged at the lower end of the LED light source 2 for monitoring the brightness of the LED light source 2, and a water drop sensor 4 is also arranged at the top of the pole 1 for determining whether it is a rainy day environment and controlling the brightness of the LED light source 2 through the controller and the light sensor 3; the light collecting component 5 is composed of a parabolic reflector 51, the parabolic reflector 51 can be rotatably arranged at the lower end of the LED light source 2 and the open end of the parabolic reflector 51 is opposite to the light sensor 3 to prevent the light of the LED light source 2 from being scattered in rainy days and interference from external light sources; in specific use, when the LED light source 2 is normally lit, the light sensor 3 can receive sufficient light intensity. The LED light source 2 is 260W and is used for lighting large places such as urban main roads or squares. Illuminance refers to the luminous flux received per unit area, and the unit is lux. There are different standards for lighting intensity for street lights in different places;
[0032] The average illumination of urban main roads is generally required to be 30 lux to ensure that vehicles can travel safely at a higher speed and pedestrians can clearly identify directions and surroundings.
[0033] The average illumination of urban secondary roads is usually 15 lux, which can meet the basic needs of vehicles driving at a lower speed and pedestrians walking.
[0034] If a street lamp fails, the light intensity detected by the light sensor 3 will be lower than the normal level, which triggers an alarm signal to be transmitted to the signal receiving and output module 63 in the control system 6 for analysis by the microprocessor 64, and then transmitted to the remote management platform through the Internet of Things module 62. The management platform determines whether the street lamp is faulty by analyzing the data. If a fault occurs, the location of the faulty street lamp can be accurately located, which is convenient for maintenance personnel to deal with it in time;
[0035] refer to Figure 1 The lower end of the vertical pole 1 is fixed with a base 8, the outer periphery of the vertical pole 1 is provided with a bracket 11, the upper end of the bracket 11 is fixed with a solar panel 7 by bolts, and the left side of the vertical pole 1 is integrally provided with an extension rod 13 for mounting the LED light source 2 and the parabolic reflector 51. The upper surface of the bracket 11 is fixed with a light sensor 3 and a protective cover 10 by bolts, and the light sensor 3 is in the protective cover 10, and the protective cover 10 is spherical and has an opening on one side facing the open end of the parabolic reflector 51. The front side of the extension rod 13 is welded with a mounting frame 52, and the rear side of the mounting frame 52 is rotatably mounted with the parabolic reflector 51.
[0036] The parabolic reflector 51 can be made of glass, plastic or metal:
[0037] Glass, optical glass is a high-quality material, such as borosilicate glass. It has the characteristics of high transparency, low absorption and low scattering, and can effectively reflect and refract light to ensure high-quality transmission of light. Its refractive index is stable and the light path can be precisely controlled. It can withstand a certain degree of temperature changes, and its thermal expansion coefficient is relatively small, which is very important for maintaining the shape accuracy of the reflector. Ordinary glass also has certain applications and is relatively cheap. However, its optical performance may not be as good as optical glass. For example, there may be more impurities and bubbles inside, which leads to increased absorption and scattering of light. However, in some occasions where the precision of the reflector is not extremely high;
[0038] Metal, aluminum can be used. Aluminum is a commonly used metal material. It has high reflectivity, especially in the ultraviolet and visible light bands, and has good light reflection performance. In addition, aluminum is relatively soft and easy to process into a parabolic shape. Achieve efficient use of light energy;
[0039] Silver has a higher reflectivity than aluminum in the visible light range, but silver is easily oxidized and requires special protection treatment, such as coating with a protective film. In optical instruments, for situations where reflectivity is extremely high, silver can be used as a reflector material after taking appropriate protective measures;
[0040] Plastics, some high-performance optical plastics, such as polymethyl methacrylate (PMMA), can be used to make parabolic reflectors 51. They have the advantages of being light and easy to shape. For example, in some portable optical devices or devices with high weight requirements, PMMA parabolic reflectors 51 can reduce the overall weight. However, the optical properties of plastics are generally not as good as those of glass and metals. For example, they have a lower hardness, are easily scratched, and may deform in a high temperature environment, affecting the reflection effect.
[0041] When choosing a parabolic reflector 51, thickness must also be considered:
[0042] The thickness consideration for large parabolic reflectors 51 is to ensure that the reflectors can maintain shape accuracy under the influence of their own gravity and external environment (such as temperature changes, vibrations, etc.). The thickness may be several millimeters, and the thickness is 3-5 millimeters. This is because small reflectors are less affected by external forces and their own gravity, and thinner thickness can reduce cost and weight. At the same time, for plastic reflectors, the thickness can also be made thinner under the premise of ensuring its shape stability to give full play to its light weight advantage;
[0043] refer to Figure 3 and Figure 4 A rotating handle 53 is fixed to the fixing seat of the parabolic reflector 51 , and one end of the rotating handle 53 extends to the rear side of the mounting frame 52 and is rotatably connected to the mounting frame 52 through a bearing for controlling the rotation of the parabolic reflector 51 . A limiting block 54 is welded to the periphery of the turning handle 53, and the periphery of the turning handle 53 located in front of the limiting block 54 is elastic and sleeved with a conical block 55; a V-shaped spring piece 56 is welded between the front side of the conical block 55 and the rear side of the mounting frame 52, and a plurality of V-shaped spring pieces 56 are arranged in a ring shape with the center of the conical block 55. The V-shaped spring pieces 56 are made of copper, and the number is 3-6; when the rear end of the conical block 55 and the limiting block 54 are pressed against each other, the turning handle 53 cannot be rotated to change the angle of the parabolic reflector 51. Before changing the angle of the parabolic reflector 51, the rear end of the conical block 55 needs to be separated from the limiting block 54; a conical groove 57 is provided on the front side of the limiting block 54 for engaging with the rear end of the conical block 55, and a groove 58 is provided on the outer surface of the conical block 55 for anti-slip.
[0044] refer to Figure 5The control system 6 includes a shell, a circuit board 61, an Internet of Things module 62, a signal receiving and outputting module 63, a microprocessor 64 and a power management module 65; the shell is fixed to the pole 1 and the circuit board 61 is fixed inside the shell, and the Internet of Things module 62, the signal receiving and outputting module 63, the microprocessor 64 and the power management module 65 are welded on one side of the circuit board 61.
[0045] refer to Figure 6 and Figure 7 , Figure 8 A drainage port 12 is provided in the rod wall of the vertical rod 1 near the base 8, and a drainage assembly 9 is provided on the inner wall of the vertical rod 1 opposite to the drainage port 12; the drainage assembly 9 includes a moving block 91 and a conical seat 92, the moving block 91 and the conical seat 92 are interlocked with each other and the moving block 91 can be slidably arranged in the vertical rod 1 for blocking the drainage port 12; a conical through groove 95 is provided in the lower end of the moving block 91, the slope surface of the conical seat 92 is pressed against the inner wall of the conical through groove 95, an electric telescopic rod 94 is fixed to the inner wall of the vertical rod 1, and the output end of the electric telescopic rod 94 is fixed to the upper surface of the moving block 91 for driving the moving block 91 to rise and fall; a through hole 93 is provided at the upper end of the moving block 91, and the through hole 93 is connected to the conical through groove 95 for guiding rainwater to flow into the drainage port 12. A plurality of drainage ports 12 are arranged in a ring around the center of the vertical rod 1, and the drainage ports 12 are arranged to be tilted downward to prevent rainwater from flowing back from the outer surface of the vertical rod 1.
[0046] Working principle: The device is provided with a light sensor 3, a water drop sensor 4 and a solar panel 7 on the pole 1. The solar panel 7 is used to provide power to the device. The light sensor 3 can detect the working condition of the LED light source 2. At the same time, the water drop sensor 4 can detect the amount of rain. Finally, the control system 6 receives and sends data to monitor the working condition of the device in time.
[0047] In specific use, when the LED light source 2 is normally on, the light sensor 3 can receive sufficient light intensity. If the street light fails to light, the light intensity detected by the light sensor 3 will be lower than the normal level, which will trigger an alarm signal to be transmitted to the signal receiving and output module 63 in the control system 6 for analysis by the microprocessor 64, and then the data is transmitted to the remote management platform through the Internet of Things module 62. The management platform determines whether the street light is faulty by analyzing the data. If a fault occurs, the location of the faulty street light can be accurately located, which is convenient for maintenance personnel to deal with it in time, improving maintenance efficiency while being widely popularized and reducing maintenance costs;
[0048] When the light sensor 3 detects the LED light source 2, it will firstly irradiate the light source of the LED light source 2 to the light sensor 3 through the parabolic reflector 51 in the light collecting component 5, so that the light emitted by the LED light source 2 can be sensed most directly, and the dispersion of ambient light in rainy days and the interference of external ambient light on the light sensor 3 can be avoided, so that the detection of the light sensor 3 is more accurate, which is convenient for correctly controlling the brightness of the LED light source 2 and is conducive to energy saving;
[0049] When installing the parabolic reflector 51, the conical block 55 can be first pushed to separate from the stop block 54 and then the handle 53 can be turned to drive the parabolic reflector 51 to change the angle corresponding to the light sensor 3, so as to facilitate the parabolic reflector 51 to collect light;
[0050] In addition, in order to prevent the sealing system of the equipment from aging and water ingress due to long-term use, the water drop sensor 4 can cooperate with the light sensor 3 and the control system 6 to automatically increase the brightness according to the environment when it detects rainy days, so as to ensure the lighting effect and improve traffic safety; at the same time, when the water drop sensor 4 detects rainy days, in order to avoid water accumulation inside the device, the control system 6 will control the electric telescopic rod 94 to start pulling the moving block 91 in the drainage assembly 9 to move up and separate from the drainage port 12, and the accumulated water will flow out from the drainage port 12, so as to avoid water accumulation inside the device;
