TECHNICAL FIELD

[0001] The present application relates to the field of guardrails, in particular to a guardrail structure with a function of reducing wind resistance coefficient and a manufacturing process thereof. BACKGROUND

[0002] In extremely cold regions, wind-blown snow often occurs, that is, when the wind and snow flow reaches the highway, the wind speed is reduced due to factors such as terrain and vegetation, and when the wind speed is less than the threshold wind speed of snow particles, the snow particles are deposited on the road surface, reducing the driving visibility, and the thickness of the snow also gradually increases, resulting in traffic interruption.

[0003] The commonly used guardrails on the highway mainly include corrugated beam guardrails, concrete guardrails and cable guardrails. Among them, the structure of the corrugated beam guardrail is relatively permeable, and the line of sight induction effect is better. The structure of the cable guardrail is more permeable than the corrugated beam guardrail, but due to the setting form of the cable guardrail, the structural strength of the cable guardrail is low, so the corrugated beam guardrail is usually set in the extremely cold area.

[0004] However, in the actual use process of the corrugated beam, due to the large width of the corrugated plate, the overall wind resistance coefficient of the guardrail is large, and the snow particles are still easily blocked, resulting in the phenomenon of snow accumulation at the guardrail.

DETAILED DESCRIPTION

[0028] The following will be described in detail in combination with the accompanying drawings Figures 1-3 The present application will be further described in detail.

[0029] The embodiment of the present application discloses a guardrail structure with a function of reducing wind resistance coefficient. Referring to Figure 1 and Figure 2The utility model provides a guardrail structure with the function of reducing the wind resistance coefficient, which comprises a plurality of stand columns 1 and windward beams 2, and each windward beam 2 is uniformly arranged on each stand column 1. The side, away from the stand column 1, of each windward beam 2 is provided with a first windward arc surface 21, and the side, close to the stand column 1, of each windward beam 2 is provided with a second windward arc surface 22. The first windward arc surface 21 and the second windward arc surface 22 provide a guide for snow particles, reduce the blocking effect of the windward beam 2 on the snow particles, facilitate the stable discharge of the snow particles from the guardrail structure, and thus reduce the possibility of snow accumulation at the guardrail structure.

[0030] Referring to Figure 2 In order to facilitate the installation of the windward beam 2, each stand column 1 is provided with a connecting assembly 3 for connecting the windward beam 2. The connecting assembly 3 comprises a windward frame 31 and a supporting seat 32, and the windward frame 31 is arranged on the stand column 1. The supporting seat 32 is arranged on the side, away from the stand column 1, of the windward frame 31, and the supporting seat 32 is provided with a supporting hole 321, and the windward beam 2 is arranged in the corresponding supporting hole 321.

[0031] In order to improve the limiting effect on the windward beam 2, each supporting seat 32 is provided with a limiting seat 33. Each limiting seat 33 extends into the supporting hole 321, and the limiting seat 33 abuts against the windward beam 2.

[0032] When the windward beam 2 needs to be installed, the worker installs the windward frame 31 on the corresponding stand column 1, and then installs the supporting seat 32 on the corresponding windward frame 31. The worker then aligns the windward beam 2 with the corresponding supporting hole 321, so that the windward beam 2 is clamped into the corresponding supporting hole 321. At this time, the windward beam 2 is supported by the supporting hole 321, so as to work more stably. The worker then clamps the limiting seat 33 into the corresponding supporting hole 321, so that the limiting seat 33 abuts against the windward beam 2. At this time, the limiting seat 33 limits the windward beam 2, so that the windward beam 2 is not easy to move during use, thereby further improving the stability of the windward beam 2 during use.

[0033] Referring to Figure 2 The side, away from the windward beam 2, of the limiting seat 33 is provided with a third windward arc surface 331. When the snow particles contact the limiting seat 33, the third windward arc surface 331 provides a guide for the snow particles, so that the snow particles are not easy to accumulate at the limiting seat 33, thereby further reducing the phenomenon of snow accumulation at the guardrail structure.

[0034] Referring to Figure 1 The windward frame 31 is provided with a snowfall hole 311 arranged in the vertical direction, so that the snow particles are not easy to accumulate at the top of the windward frame 31, and the snow particles can directly fall to the ground or be discharged when passing through adjacent two windward beams 2.

[0035] Referring toFigure 2 In order to improve the structural strength of the windward frame 31, a wind guide slope 312 is arranged on the windward frame 31, the wind guide slope 312 is arranged on the side of the windward frame 31 close to the support seat 32, and the end of the wind guide slope close to the column 1 is arranged to be inclined downward compared to the side close to the support seat 32. At this time, the wind guide slope 312 plays the role of a reinforcing rib, improves the structural strength of the windward frame 31, so that the windward frame 31 and the support seat 32 can more stably support the windward beam 2. At the same time, under the action of the wind guide slope 312, the windward frame 31 is not easy to block the lateral snow particles, thereby further reducing the possibility of snow accumulation at the windward frame 31.

[0036] With reference to Figure 3 In order to facilitate the installation of the guardrail structure, the column 1 is embedded in the ground and connected with a pre-buried box 4. A plurality of heat transfer assemblies 5 are arranged in the pre-buried box 4, and each heat transfer assembly 5 corresponds to one column 1. The heat transfer assembly 5 includes a heat transfer plate 51 and a storage tank 52 containing phase change material, and the storage tank 52 is arranged in the pre-buried box 4. One end of the heat transfer plate 51 extends into the storage tank 52, and the other end extends into the corresponding position of the column 1, and the heat transfer plate 51 abuts against the inner wall of the column 1. In the embodiment of the application, the phase change material uses paraffin type phase change material, so as to dissipate heat when the temperature is low, and conduct heat to the column 1 through the heat transfer plate 51.

[0037] When the external temperature reaches the heat release temperature of the phase change material, the heat emitted by the phase change material is transmitted through the heat transfer plate 51. Since the heat transfer plate 51 abuts against the inner wall of the column 1, the heat transfer plate 51 can conduct the heat emitted by the phase change material to the column 1, which facilitates heating of the column 1, thereby reducing the possibility of snow accumulation on the part of the column 1 close to the ground.

[0038] With reference to Figure 3 A plurality of heat expansion holes 511 are arranged on the heat transfer plate 51, which facilitates the heat transfer plate 51 to conduct heat to the column 1 more uniformly, so that the heat is not easy to accumulate, thereby improving the temperature uniformity of the column 1 as a whole.

[0039] With reference to Figure 3 In order to improve the stability of the heat transfer assembly 5 during work, a plurality of heat uniformizing assemblies 6 are arranged in each column 1. The heat uniformizing assembly 6 includes a heat uniformizing frame 61 and a plurality of heat uniformizing wheels 62, and the heat uniformizing frame 61 is slidingly connected in the column 1 in the vertical direction. Each heat uniformizing wheel 62 is uniformly arranged along the circumference of the heat uniformizing frame 61, and each heat uniformizing wheel 62 is rotationally connected with the heat uniformizing frame 61.

[0040] In the process of heat transfer plate 51 transferring heat, each uniform heat frame 61 is started at the same time and drives the uniform heat wheel 62 at the corresponding position to move, the uniform heat wheel 62 is in contact with the heat transfer plate 51 and makes the heat transfer plate 51 more stably abut on the inner wall of the column 1, so that the heat transfer plate 51 more stably transfers heat to the column 1.

[0041] Referring to Figure 3 In order to facilitate the control of each group of uniform heat components 6, the adjacent two uniform heat frames 61 are connected through the connecting rod 7. The cam 8 is rotatably connected in the column 1, the control rod 81 is rotatably connected on the cam 8, and the end of the control rod 81 away from the cam 8 is rotatably connected with the uniform heat frame 61 close to the embedded box 4. The shaft of the cam 8 extends into the embedded box 4, and the embedded box 4 stores a motor, which facilitates the control of the cam 8. And the embedded box 4 stores a storage battery, which is electrically connected with the external electric box to charge the storage battery.

[0042] When it is necessary to control each uniform heat frame 61 synchronously, the cam 8 is rotated to drive the control rod 81 to rotate, and the control rod 81 controls the closest uniform heat frame 61 to reciprocate in the vertical direction. Under the action of the connecting rod 7, the uniform heat frame 61 can control the adjacent uniform heat frame 61 to reciprocate in the vertical direction, thereby realizing the function of synchronously controlling each uniform heat frame 61 to work, facilitating each group of uniform heat components 6 to apply pressure to the heat transfer plate 51 at different positions, and improving the stability of the heat transfer plate 51 during use.

[0043] The implementation principle of the guardrail structure with the function of reducing the wind resistance coefficient is that: in the process of using the guardrail structure, the first windward arc surface 21, the second windward arc surface 22 and the third windward arc surface 331 cooperate to provide guidance for snow particles, so that the snow particles are not easily blocked at the windward beam 2, and the snow particles are conveniently discharged. At the same time, under the action of the heat transfer assembly 5, the temperature at the column 1 is appropriately increased, so that the position close to the ground of the column 1 is not prone to snow accumulation, thereby reducing the possibility of snow accumulation at the guardrail structure and improving the safety of the guardrail structure during use.

[0044] The embodiment of the present application also discloses a manufacturing process of a guardrail structure, which adopts the following technical scheme. A manufacturing process of a guardrail structure comprises the following steps: according to the resistance coefficient calculation formula C d =f d / 0.5pv 2 A, obtaining the horizontal resistance Fd of air acting on the guardrail, air density p, incoming flow wind speed v, and calculating area A according to the protection level; According to the formula content, the first windward arc surface 21 and the second windward arc surface 22 are arranged in the windward beam 2; The windward beam 2 is erected on each column 1 to form the final guardrail structure.
