[0002] The main purpose of municipal construction is to facilitate the lives of citizens and promote the development of urban material and spiritual civilization. For example, public facilities such as roads, drainage, and bridges are constructed to achieve the goal of improving the economic prosperity of the city.

[0003] Municipal construction guardrails, also known as highway guardrails, isolation guardrails, etc., are a common facility on urban roads. They mainly play the role of isolation, non-isolation, sidewalks and non-motor vehicle lanes. They are usually composed of components such as columns, horizontal beams or vertical beams and fixings, and most of their overall materials are made of steel.

[0004] When the guardrail is installed in the form of vertical beams, there will be a certain gap between the vertical beams. In daily life, some pedestrians will crawl through the gap to save time. When the guardrail is installed in the form of horizontal beams, some pedestrians will step on the horizontal beams to climb over the guardrail, which may easily interfere with the normal traffic order, affect the normal passage of other pedestrians and vehicles, and may even cause traffic accidents.

The baffle frame 12 can be driven to rise by the output end of the electric push rod 11, so that in some special circumstances, such as emergency passage of fire trucks and ambulances, the baffle frame 12 can be opened to provide convenience and reduce unnecessary losses. The curtain panel 13 can also play a protective role in normal times, and its surface is smooth, which can reduce the possibility of pedestrians climbing.

[0032] See also Figure 3 Soft needles 21 are embedded in the outer wall of the first rotating drum 6, and the soft needles 21 are arranged in a surrounding manner; when working, the soft needles 21 can provide a certain resistance and tingling sensation when the pedestrian holds the first rotating drum 6 in his hand.

[0033] See also Figure 1 A bottom plate 22 is installed at the bottom of the installation frame 1, and a rubber pad is laid at the bottom of the bottom plate 22; during operation, the friction between the bottom of the installation frame 1 and the ground is increased by setting the rubber pad.

[0034] Working principle: By setting multiple groups of blocking rods 5 on the vertical beams 2, the gaps between the vertical beams 2 can be blocked to reduce the risk of pedestrians drilling through the gaps between the vertical beams 2. The blocking rods 5 can be elastically reset and slid on the vertical beams 2 through the second connecting shaft 4 in conjunction with the springs 7. When pedestrians choose to climb, the blocking rods 5 can slide down on the surface of the vertical beams 2 under the action of the springs 7 to reduce the possibility of pedestrians stepping on the blocking rods 5 to climb, reduce the interference caused by crossing the guardrails to the normal traffic order, and reduce the danger of traffic accidents. At the same time, the elasticity of the springs 7 can play a certain buffering role. The bellows 9 can protect the spring 7 and reduce the corrosion caused by external impurities and rainwater, so as to increase the service life of the spring 7.

Convenience, reducing unnecessary losses, and the curtain board 13 can also play a protective role in normal times. Its surface is smooth, which can reduce the possibility of pedestrians climbing; the protective rod 15 is combined with the spring column 14, which can be elastically buffered when a vehicle loses control and hits the guardrail, so as to reduce the damage to the guardrail as a whole and reduce the possibility of the guardrail being deflected. At the same time, the second rotating drum 16 can convert the impact force into rotational kinetic energy when the vehicle hits, so as to disperse the force and reduce the impact; through the arrangement of multiple sets of receiving plates 18 and reinforcing rods 17, the contact surface between the mounting frame 1 and the ground is increased. The inclined setting of the reinforcing rod 17 can support the installation frame 1 and reduce the phenomenon of the installation frame 1 tipping over; the lighting lamp 19 can illuminate the road, and the reflector 20 can reflect the light from the vehicle headlight when the lighting lamp 19 is damaged to remind the driver of the position of the installation frame 1 and reduce the possibility of the vehicle hitting the installation frame 1; the soft thorn needle 21 can provide a certain resistance and tingling sensation when the pedestrian holds the first rotating drum 6; the rubber pad is set to increase the friction between the bottom of the installation frame 1 and the ground.
