Description

Technical Field

[0001] This utility model relates to the field of anti-glare guardrail technology, specifically an anti-glare warning guardrail for highways. Background Technology

[0002] Anti-glare warning barriers, also known as metal mesh, anti-throw netting, sheet metal, perforated plates, and anti-glare guardrails, are mainly installed in the median strip of highways. By changing the direction of some vehicle headlights, they reduce the intensity of direct light, thereby reducing glare interference to drivers.

[0003] However, existing anti-glare warning guardrails cannot be intelligently adjusted during use. Therefore, dark-background warning strips are often used to prevent glare, which greatly reduces the warning effect of the strips in non-glaring weather or at night, resulting in a lack of effective road indication function and posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-glare warning guardrail for highways to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-glare warning guardrail for highways, comprising a protective top rail, a protective middle rail, and a protective bottom rail. The protective top rail, the protective middle rail, the protective bottom rail, and a water collection tank are sequentially and fixedly connected. A water collection tank and a control box are fixedly installed on one side of the protective bottom rail. A light-blocking plate is movably connected inside the protective top rail. The water collection tank stores rainwater and steam, and the steam drives the light-blocking plate to move.

[0006] As a further embodiment of this utility model: a glare-proof warning guardrail for highways, wherein the water collection tank has an opening inside, one end of the opening is connected to the outside of the water collection tank, the other end of the opening is connected to the inside of the water collection tank, and one end of the water collection tank is connected to a control box through an air supply pipe.

[0007] As a further embodiment of this utility model: a glare-proof warning guardrail for highways, wherein the control box includes a movable cavity, a guide rod and a wedge, one side of the movable cavity is connected to the control box, and the other end of the movable cavity is movably connected to a movable rod, the movable rod is fixedly connected to a light-blocking plate, and the height of the end of the movable rod that contacts the wedge is lower than the height of the end of the movable rod that contacts the light-blocking plate.

[0008] As a further embodiment of this utility model: a glare-proof warning guardrail for highways, wherein the outer side of the guardrail is covered with reflective strips.

[0009] As a further embodiment of this utility model: an anti-glare warning guardrail for highways, wherein both ends of the guide rod are fixedly connected to the movable cavity, the wedge is movably connected to the guide rod, and the wedge is adapted to the movable rod.

[0010] As a further embodiment of this utility model: a highway anti-glare warning guardrail, wherein the end of the movable rod away from the light-blocking plate is set in a conical shape.

[0011] As a further embodiment of this utility model: a highway anti-glare warning guardrail, wherein the top of the water collection tank is provided with a trough for collecting rainwater.

[0012] As a further solution of this utility model: a glare-proof warning guardrail for highways, wherein the inside of the bend is provided with a bend for isolating a water collection tank from the outside.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The protective top rail, middle rail, bottom rail, and water collection tank are sequentially and fixedly connected. A water collection tank and control box are fixedly installed on one side of the bottom rail. A light-blocking plate is movably connected inside the protective top rail. The water collection tank stores rainwater and steam, and the steam drives the light-blocking plate to move. Specifically, one side of the movable cavity is connected to the control box, and the other end of the movable cavity is movably connected to a movable rod. The movable rod is fixedly connected to the light-blocking plate. Therefore, after the rainwater stored in the water collection tank evaporates due to the intense sunlight, the steam will be input into the movable cavity through the gas pipe and lift the wedge block to move along the guide rod. After the wedge block moves upward, it will squeeze the movable rod and make the movable rod tilt upward, so that the light-blocking plate can protrude from the protective middle rail and provide a certain degree of shielding for the protective middle rail, avoiding the problem of glare caused by sunlight reflection on the reflective stickers on the protective middle rail.

[0015] 2. Because the water collection tank has an internal bend, one end of which is connected to the outside of the water collection tank and the other end of which is connected to the inside of the water collection tank, and one end of the water collection tank is connected to the control box through a gas supply pipe, and a trough is provided on the top of the water collection tank for rainwater collection, and the inside of the bend has a bend for isolating the water collection tank from the outside world, so that in dry weather, the water collection tank can be isolated from the external environment through the bend to avoid the problem of steam escape.
