Description

Technical Field

[0001] The utility model relates to the technical field of combined delineator facilities for expressways. Background Art

[0002] Highway delineators are an important part of highway safety facilities. Their function is to enable drivers to clearly identify road contours and avoid traffic accidents caused by unclear vision. They are essential traffic safety facilities to ensure driving safety.

[0003] With the continuous growth of highway traffic volume, higher requirements are placed on the visibility, recognition and durability of traffic signs. However, traditional highway delineators must be connected to the corrugated guardrail with connecting bolts during installation. The guardrail bolts must be disassembled and installed, and there are problems such as non-standard distances and cumbersome replacement and maintenance, which are difficult to meet the needs of modern intelligent and efficient maintenance. Therefore, the development of a new type of highway assembled delineator is of great significance to improving the safety and traffic efficiency of highways.

[0004] Although the proportion of delineators in traffic safety facilities is relatively small, their role cannot be ignored. Delineators must be installed on highway corrugated guardrails, especially on expressways and first-class highways, where vehicles travel at high speeds and vehicles have a short visual distance during nighttime driving, which greatly reduces driving safety. Today, let's learn about the relevant knowledge of highway corrugated guardrail delineators.

[0005] Attached delineators refer to a combined structure consisting of a mounting bracket, a retroreflector, and a connector. Depending on the object of attachment, they can be classified into: corrugated beam guardrail delineators, concrete guardrail delineators, tunnel sidewall delineators, and cable guardrail delineators, among which corrugated guardrail attached delineators are the most widely used. For example, the delineators on the corrugated guardrails of existing highways are generally set every 8 meters or 4 meters.

[0006] Existing attached contour markers are generally installed destructively on corrugated guardrails, that is, holes are drilled on the corrugated guardrail and the contour markers are installed on the corrugated guardrails through bolt assemblies. Drilling will reduce the rigidity of the corrugated guardrail, and the guardrail contour markers cannot be repositioned after installation. When the position needs to be changed, new holes need to be drilled.

[0007] Meanwhile, the existing delineators only have a reflective effect and a single function. Summary of the invention

[0008] This project aims to study and design a new type of highway modular delineator that is easy to install and maintain. By separating the delineator frame from the reflective film, the delineator can be quickly assembled, replaced and repaired, and it also has the function of Internet of Things, thereby improving the traffic and safety level of the highway.

[0009] The technical solution adopted by the utility model to solve its technical problems is:

[0010] A combined highway delineator includes a mounting portion, a light-emitting component and an Internet of Things component, and is characterized in that: the mounting portion is composed of a main board, a backboard and fastening screws, wherein the main board is an S-shaped profile and is fitted on the front of the corrugated guardrail, and has a top plate on the top of the main board, the top plate is relatively horizontally arranged, and an upper mounting space and a lower mounting space are formed on the main board, the light-emitting component and the Internet of Things component are respectively fixed at the upper mounting space and the lower mounting space; the backboard is a C-shaped profile and is fitted on the back of the corrugated guardrail, the main board and the backboard both have an extension portion, at which the main board and the backboard are fitted and clamped on the upper edge of the corrugated guardrail, and the extensions of the main board and the backboard are clamped on the corrugated guardplate and fixed by fastening screws.

[0011] Furthermore, micro protrusions and grooves with anti-slip design are arranged on the extended parts of the main board and the back board.

[0012] Furthermore, the extended portion of the back plate or / and main plate is designed to be thickened, and the increased thickness of the thickened portion is equivalent to the thickness of the corrugated guardrail.

[0013] Furthermore, the light-emitting component is an injection-molded part and a reflective film adhered to the surface of the injection-molded part, and the injection-molded part is fixedly connected to the mainboard by fastening screws or a snap-on structure.

[0014] Furthermore, the light-emitting component is an aluminum plate and a reflective film adhered to the surface of the aluminum plate, and the aluminum plate is fixed to the main board by welding.

[0015] Furthermore, the surface where the reflective film is pasted is an inclined surface and is set at an angle toward the lane.

[0016] Furthermore, the housing of the Internet of Things component is injection molded, and a vibration sensor, a control circuit, a wireless communication module, a lithium battery and a camera are installed in the Internet of Things component, wherein one camera is arranged facing forward and backward, and the wireless communication module is wirelessly connected to the background central control system. When the vibration sensor in the Internet of Things component detects an abnormal sound, it wakes up the control circuit and controls the camera to take pictures for evidence collection.

[0017] Furthermore, a micro photovoltaic power generation panel is installed on the top plate, and the micro photovoltaic power generation panel is connected to a lithium battery through a control circuit.

[0018] Furthermore, the IoT components are potted and cured, and are IPX8 grade waterproof.

[0019] Furthermore, the main board and the back board are both integrally formed aluminum alloy profile components.

[0020] The beneficial effects of the utility model are:

[0021] The design of this project uses highly durable materials and a split design to reduce material and installation costs, simplify the installation and maintenance of road facilities, and enable rapid replacement of damaged parts, which helps reduce workers' labor intensity, improve work efficiency, and reduce maintenance costs.

[0022] This project adds the Internet of Things photo-taking and evidence-collecting function on the original basis, which can achieve real-time evidence collection of vehicles that hit the guardrail.

[0036] A combined highway contour marker, which includes a contour-designed mounting portion, and a light-emitting component and an Internet of Things component mounted on the mounting portion, wherein the mounting portion is preferably made of an aluminum alloy profile, which has the characteristics of stable size and light weight.

[0037] Specifically, the mounting portion is composed of a main board 10, a back board 20 and fastening screws 30, wherein the main board is an S-shaped profile, which is fitted on the front side of the corrugated guardrail, that is, the side facing the road surface, which is the working surface, and has a top plate 11 on the top of the main board, which is relatively horizontally arranged and forms an upper mounting space at this position, and the trough below is the lower mounting space. The main board is integrally formed, and the material is an aluminum alloy profile, which is formed by truncation. The upper edge of the main board 10 has an extension 12, and the extension 12 is provided with micro protrusions and grooves, and is provided with a through hole 13.

[0038] The back plate 20 has a C-shaped profile and is fitted on the back of the corrugated guardrail, that is, facing the outside of the roadbed, which is a non-working surface. The upper edge of the back plate has an extension portion 21, which is provided with micro-protrusions and grooves and threaded holes 22.

[0039] The above-mentioned main board and back board both have an external extension part, where the main board and the back board are attached and clamped on the upper edge of the corrugated guardrail, and are fastened with fastening screws 30. After fastening, the main board and the back board are clamped on the corrugated guard plate 00. After fastening, the back board and the main board are fixed firmly under the joint clamping action.

[0040] An optimal preferred structure is a thickening design at the outer edge extension portion 21 of the back plate 20. The thickness increase of the thickened portion is equivalent to the thickness of the corrugated guardrail, and a threaded hole is set in the thickened portion. Correspondingly, a bolt hole is set on the outer edge of the main board. The above-mentioned screws are inclined and tightened from top to bottom. After tightening, the above-mentioned back plate and main board are supported on the corrugated guardrail 00, and the first band of the corrugated guardrail is supported, thereby achieving a secure fixation and a higher connection strength.

[0041] Furthermore, the thickening design on the back panel mentioned above can also be replaced by a thickening design of the extended portion on the main board.

[0042] The light-emitting component 40 is preferably an engineering plastic injection molded part. The component is integrated with the panel by fastening screws or a snap-on structure. Specifically, the two sides of the component are reflective film pasting surfaces. In order to achieve the best reflection effect and to help the driver to warn, the two sides are designed at an angle toward the lane and increase a certain curvature so that the driver can best observe the reflective effect. A reflective film 41 is pasted there, and the pasting uses a high-strength adhesive, which is maintenance-free for life. The reflective module is installed in the trough.

[0043] Furthermore, the above-mentioned light-emitting assembly may also be two aluminum alloy plates welded at an angle, and a reflective film 41 is pasted on the aluminum alloy plates.

[0044] The Internet of Things component 50 has an injection-molded shell, and a vibration sensor, a control circuit, a wireless communication module, a lithium battery and a camera 51 are installed in the Internet of Things component. Among them, one camera is set towards the front and one towards the back, respectively, to take pictures in the front and rear directions. The wireless communication module uploads the images obtained by taking pictures to the central control system for backup and archiving.

[0045] The vibration sensor, control circuit, wireless communication module and lithium battery are installed inside the shell. The above-mentioned IoT components are potted and cured to achieve IPX8 level waterproof.

[0046] The above-mentioned Internet of Things component is installed in the triangular area of ​​the main board, and a micro photovoltaic power generation panel 52 is installed on the top of the housing of the Internet of Things component to charge the lithium battery through photovoltaic power generation.

[0047] When a vehicle hits the guardrail, which is a metal component with excellent sound transmission effect, the vibration sensor in the IoT component detects abnormal sound, wakes up the control circuit, and controls the camera to take photos for evidence collection. The photo collection adopts a continuous shooting method, for example, one photo is taken every 1 millisecond, and three photos are taken in a row to obtain the original evidence. The evidence collection can effectively fix the evidence of the accident vehicle.

[0048] In theory, the structures could be set up every few dozen meters to monitor highways.

[0049] The camera in this embodiment will only take photos for evidence when a vehicle hits the corrugated guardrail. It is usually in standby mode, so it has low power consumption. The power operation demand can be met by a micro lithium battery and a micro solar photovoltaic panel. For example, it can meet the power requirements even in a week of continuous rainy days.

[0050] In this embodiment, the main board 10 and the back board 20 are made of aluminum alloy profiles, which will not rust, can achieve both aesthetics and rigidity, and are maintenance-free for life.

[0051] The above-mentioned functional module is fixed to the main board by screws or clips. When the functional module cannot be used, the functional module can be repaired or replaced separately, that is, the structural design is excellent.

[0052] The combined design of the back panel and the main board can be installed and disassembled with one click by tightening the screws. There is no need to drill holes on the guardrail. It is a non-destructive installation method that can achieve fast and stable installation and disassembly without destroying the rigidity of the original guardrail.

[0053] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements to the present invention by relevant technical personnel in the field should fall within the scope of protection determined by the claims of the present invention.
