Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of highway traffic safety protection, especially relates to a novel highway traffic safety protection device. BACKGROUND

[0002] Highway safety guardrails are safety facilities set on both sides of highways or central medians, used to prevent vehicles from driving off the road or intruding into oncoming lanes, thereby protecting the safety of vehicles and pedestrians. They are usually composed of upright columns, crossbeams, protective plates, and other components, with certain height, strength, and rigidity. Guardrails can absorb energy through their own deformation when vehicles collide, reducing the collision speed of vehicles and the severity of accidents.

[0003] Existing guardrails have some deficiencies in installation stability. For example, the upright column foundation of some guardrails is not designed reasonably enough, and in poor geological conditions or under the impact of large external forces, the upright columns may tilt or loosen, affecting the overall stability and protection effect of the guardrails. In addition, the connection method of some guardrails is not firm enough, and after long-term use, the connection may loosen, leading to a decrease in the overall structure of the guardrails.

[0004] In terms of rain protection of connecting fasteners, existing guardrails also have defects. Connecting fasteners are usually exposed to outdoor environments and are prone to rust and corrosion due to rainwater erosion, reducing their fastening performance. Once the fasteners fail, the connection of the components of the guardrail will not be tight, and even the phenomenon of falling off may occur, seriously affecting the safety and service life of the guardrail.

[0021] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0022] Please see Figures 1-5 The utility model discloses a novel highway traffic safety protection device, which comprises a base 11, a vertical rod 12, a protective net 13 and a fastener 14.

[0023] The vertical rod 12 is arranged along the vertical direction, and the bottom of the vertical rod 12 is fixedly connected with the base 11; a plurality of vertical rods 12 are arranged along the width direction of the base 11 at intervals; the fastener 14 is fixedly connected to the vertical rod 12 and is used for pressing the protective net 13; and a plurality of fasteners 14 are connected to the vertical rod 12 at intervals along the vertical direction.

[0024] The protective net 13 is composed of a plurality of grid bars 131 arranged in the horizontal direction and the vertical direction.

[0025] The side surface of the fastener 14 is provided with a first groove 141 and a second groove 142, and a mounting hole 145 is arranged between the first groove 141 and the second groove 142; the mounting hole 145 is a stepped hole; the stepped hole is designed in combination with a screw; the force distribution of the connecting node is optimized; the mounting hole 145 is used for mounting a screw connected to the vertical rod 12; a cap 15 is arranged at the top of the mounting hole; the cap 15 is used for sealing the end of the mounting hole; and the loosening risk is effectively reduced by cooperating with the cap 15.

[0026] The plurality of vertical rods 12 are arranged at intervals and cooperatively act with the distributed fastener 14; through the precise clamping design of the first groove 141 and the second groove 142, a multidirectional pressing structure is formed, and the mechanical engagement strength of the protective net 13 and the vertical rod 12 is enhanced.

[0027] The first groove 141 and the second groove 142 are arranged along the vertical direction; the first groove 141 or the second groove 142 is used for accommodating the grid bar 131 arranged along the vertical direction.

[0028] The water guide cavity 143 and the mounting cavity 144 are respectively arranged on both sides of the first groove 141 or the second groove 142, and are respectively connected with the first groove 141 or the second groove 142. The mounting cavity 144 is arranged on one side of the first groove 141 or the second groove 142 close to the mounting hole, and the water guide cavity 143 is arranged on one side of the first groove 141 or the second groove 142 away from the mounting hole. The width dimension of the water guide cavity 143 along the horizontal direction is greater than the width dimension of the mounting cavity 144 along the horizontal direction, and the height dimension of the water guide cavity 143 along the vertical direction is equal to the height dimension of the mounting cavity 144 along the vertical direction.

[0029] The highway protection device is in an outdoor environment and will face weather conditions such as rain. The water guide cavity 143 is connected with the first groove 141 or the second groove 142, and a large-width cavity is connected with a drainage path, which can quickly guide out the infiltrated rainwater and avoid the retention of rainwater in the protection device.

[0030] By quickly draining rainwater, the water guide cavity 143 can effectively avoid the retention of rainwater at the connection part of the protection net 13 and the vertical rod 12, reduce the erosion of rainwater on the fastener 14 and other components, thereby prolonging the durability of the key components and maintaining the stability of the device under complex climate conditions.

[0031] The water guide cavity 143 with a larger width can provide a more spacious space, allowing rainwater to flow more smoothly and accelerating the drainage speed. Compared with the mounting cavity 144 with a smaller width, it can better bear the function of quickly guiding out rainwater and ensure that there is no water accumulation dead angle in the drainage path.

[0032] The mounting cavity 144 is arranged on one side of the first groove 141 or the second groove 142 close to the mounting hole, and is independently sealed and closed with the cap 15. It is mainly used for protecting the mounting hole and the connecting parts such as screws inside.

[0033] The water guide cavity 143 with a larger width than the mounting cavity 144 can make rainwater flow more to the water guide cavity 143, reducing the possibility of rainwater entering the mounting cavity 144, thereby providing better waterproof protection for the mounting cavity 144 and avoiding the erosion of rainwater on the connecting parts in the mounting hole, ensuring the stability of the connection.

[0034] A plurality of fasteners 14 are arranged in layers along the vertical rod 12 in the longitudinal direction, forming a multi-point support system to improve the overall impact resistance. The water guide cavity 143 and the mounting cavity 144 are separated, and the water guide cavity 143 is connected with a drainage path by a large-width cavity, which can quickly guide out the infiltrated rainwater.

[0035] The mounting cavity 144 is independently sealed and designed to cooperate with the cap 15 to be closed, so as to double the isolation of rainwater from erosion of the fastener 14, and the through layout of the water guide cavity 143 and the mounting cavity 144 ensures that there is no water accumulation dead angle in the drainage path, so as to avoid the corrosion problem caused by the retention of rainwater. The overall structure is optimized through functional division and sealing, so as to maintain the stability of the device under complex climate conditions and prolong the durability of the key components.

[0036] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
