Abstract
Description
Technical Field
[0001] This utility model relates to the field of baffles, and in particular to a splash-proof isolation baffle. Background Technology
[0002] During the maintenance, repair, and expansion of infrastructure such as highways, bridges, tunnels, and urban roads, work often needs to be carried out under conditions where traffic is simultaneously open, meaning the construction area runs parallel to the normal traffic lanes. In this situation, construction activities can easily generate high-speed flying debris such as rocks, chips, mud, sparks, and dust, posing a serious threat to passing vehicles and personnel. Implementing anti-splash measures is not only a basic requirement of safety management but also a crucial link in ensuring public safety. Barriers effectively intercept concrete fragments, molten metal droplets, and gravel particles generated during construction, preventing them from penetrating vehicle windows and causing injury or vehicle damage.
[0003] When using guardrails, in environments with high wind speeds and strong traffic disturbances, such as highways, the guardrails are prone to shaking, deformation, or even collapse. Therefore, a splash-proof guardrail is provided. Utility Model Content
[0004] The main purpose of this utility model is to provide a splash-proof isolation barrier to solve the problem mentioned in related technologies that when using isolation barriers, in environments with high wind speeds and strong traffic disturbances, such as highways, the barriers are prone to shaking, deformation, or even collapse.
[0005] To achieve the above objectives, according to one aspect of the present invention, a splash-proof barrier is provided, comprising a base, an mounting bracket fixedly mounted on the upper surface of the base, two mounting grooves symmetrically opened on the side wall of the mounting bracket, and a ventilation groove provided in the mounting groove, the ventilation groove guiding air through the mounting bracket, and further comprising: a barrier net, the barrier net being fixedly installed in the mounting groove, the barrier net blocking splashed sand and gravel.
[0006] Furthermore, the base has a trapezoidal structure.
[0007] Furthermore, the base has two symmetrically formed grooves on its sidewall, and several connecting screw holes are formed through the sidewalls of the grooves.
[0008] Furthermore, a support plate is fixedly installed on the lower surface of the base, and several fixing screw holes are opened through the upper surface of the support plate.
[0009] Furthermore, several positioning shafts are fixedly installed on the upper surface of the support plate, and the lower end of the positioning shafts has a tapered structure.
[0010] Furthermore, a limiting groove is formed through the side wall of the base, and the limiting groove has an inverted U-shaped structure.
[0011] Furthermore, two partitions are symmetrically fixedly installed on the upper end of the mounting frame, with the partitions inclined upwards at 50-60°.
[0012] Furthermore, a positioning slot is provided on one side wall of the mounting bracket, and the inside of the positioning slot has a V-shaped structure. A positioning plug that matches the positioning slot is fixedly installed on the other side of the mounting bracket.
[0013] Furthermore, the ventilation slot is an inclined structure, and several isolation shafts are fixedly installed inside the ventilation slot.
[0014] Furthermore, the isolation net is made of metal.
[0015] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the trapezoidal base structure increases the bottom support area, lowers the center of gravity, and improves the anti-overturning moment. When connecting two baffles, the connecting screw holes of the two bases are aligned, and the connecting bolts are rotated from the grooves. The connecting bolts pass through the two connecting screw holes to form a rigid splice, preventing the base from separating laterally. Bolts are installed in the internal threads of the fixing screw holes. The bolts pass through the fixing screw holes and are inserted into the ground, forming a rigid connection between the base and the ground, completely preventing overturning and displacement. The support plate distributes pressure and prevents local damage to the road surface. The lower end of the positioning insert shaft has a conical structure. During installation, the positioning insert shaft is inserted into the ground or a pre-drilled hole. The conical design facilitates alignment and reduces deviation. The positioning insert shaft provides precise vertical positioning, ensuring that the installation position of each baffle is consistent. A limiting groove is opened through the side wall of the base. The limiting groove 13 has an inverted U-shaped structure. The limiting groove enables quick connection between the base and existing infrastructure (such as water-filled barriers). The ventilation slot guides the connection. The airflow passes through the mounting frame, which has an inclined structure. Several isolation shafts are fixedly installed inside the ventilation duct. When the airflow passes through the inclined ventilation duct, it is smoothly guided along the slope to reduce frontal impact. The isolation shafts form a louvered guide grille to guide the airflow through, reduce wind pressure, and block debris from passing through. The baffle is inclined upward at 50-60°. The baffle causes splashed objects to bounce downward after impact and fall into the construction area, preventing splashed objects from entering the driveway from above the mounting frame. A positioning slot is opened on one side wall of the mounting frame. The positioning slot has a V-shaped structure inside. A positioning plug that matches the positioning slot is fixedly installed on the other side of the mounting frame. During installation, the positioning plug is aligned with the positioning slot and pushed in to automatically center it, effectively preventing splashed objects from passing through the joint. The isolation net blocks splashed sand and gravel. The isolation net is made of metal. The metal mesh intercepts splashed sand, gravel, fragments, and sparks. The mesh size of the isolation net is smaller than the size of the splashed objects. The metal material is high temperature resistant, impact resistant, and has a long service life.

[0019] This embodiment provides a splash-proof isolation baffle, including a base 1; like Figure 1 , Figure 2 , Figure 6As shown, to prevent the base 1 from tipping over due to excessive wind torque, the base 1 has a trapezoidal structure. The trapezoidal structure increases the bottom support area, lowers the center of gravity, and improves the anti-overturning moment. Two grooves 11 are symmetrically opened on the side wall of the base 1. Several connecting screw holes 111 are opened through the side wall of the grooves 11. Connecting bolts are installed in the internal threads of the connecting screw holes 111. When connecting the two baffles, the connecting screw holes 111 of the two bases 1 are aligned. The connecting bolts are rotated from the grooves 11, and the connecting bolts pass through the two connecting screw holes 111 to form a rigid splice and prevent the base 1 from separating laterally. A support plate 12 is fixedly installed on the lower surface of the base 1. Several fixing screw holes 121 are opened through the upper surface of the support plate 12. The fixing screw holes 121 are threaded internally. Bolts are installed, which pass through the fixing screw holes 121 and are inserted into the ground to form a rigid connection between the base 1 and the ground, completely preventing overturning and displacement. The support plate 12 distributes pressure and prevents local damage to the road surface. Several positioning pins 122 are fixedly installed on the upper surface of the support plate 12. The lower end of the positioning pin 122 has a conical structure. During installation, the positioning pin 122 is inserted into the ground or the reserved hole. The conical design facilitates alignment and reduces deviation. The positioning pin 122 provides precise vertical positioning to ensure that the installation position of each baffle is consistent. A limiting groove 13 is opened through the side wall of the base 1. The limiting groove 13 has an inverted U-shaped structure. The limiting groove 13 enables quick connection between the base 1 and existing infrastructure (such as water-filled barriers). like Figure 3 , Figure 4 As shown, a mounting bracket 2 is fixedly installed on the upper surface of the base 1. Two mounting slots 21 are symmetrically opened on the side wall of the mounting bracket 2. To reduce the wind resistance of the mounting bracket 2, ventilation slots 211 are provided within the mounting slots 21. The ventilation slots 211 guide airflow through the mounting bracket 2. The ventilation slots 211 have an inclined structure, and several isolation shafts 212 are fixedly installed within them. When airflow passes through the inclined ventilation slots 211, it is smoothly guided along the inclined surface, reducing frontal impact. The isolation shafts 212 form louvered guide grilles, guiding airflow through, reducing wind pressure, and simultaneously blocking debris from passing through. Two partitions 23 are symmetrically fixedly installed on the upper end of the mounting frame 2. The partitions 23 are inclined upward at 50-60°. The partitions 23 cause the splashed material to bounce downward after impact and fall into the construction area, preventing the splashed material from entering the driveway from above the mounting frame 2. A positioning slot 22 is opened on one side wall of the mounting frame 2. The positioning slot 22 has a V-shaped structure inside. A positioning plug 221 that matches the positioning slot 22 is fixedly installed on the other side of the mounting frame 2. During installation, the positioning plug 221 is aligned with the positioning slot 22 and pushed in to automatically center, effectively preventing the splashed material from passing through the splice seam. It also includes: isolation net 3, such as Figure 1 , Figure 5As shown, in order to facilitate the interception of splashing objects, the isolation net 3 is fixedly installed in the mounting groove 21. The isolation net 3 blocks the splashing sand and gravel. The isolation net 3 is made of metal. The metal mesh intercepts the splashing sand, gravel, fragments, and sparks. The mesh size of the isolation net 3 is smaller than the size of the splashing objects. The metal material is resistant to high temperature, impact, and has a long service life. In this application, the isolation net 3 is preferably made of aluminum alloy.
