Description

Technical Field

[0001] This invention belongs to the technical field of highway windshield screens, specifically relating to an intelligent windshield screen that can automatically adjust according to the crosswind intensity on highways. Background Technology

[0002] Highway windbreaks are facilities installed on specific sections of highways. They are typically installed on both sides of the road near noise-sensitive areas such as residential and commercial areas, as well as in windy or breezy sections. Their main functions are: first, to reduce noise pollution from vehicles, minimizing the impact of vehicle noise on the surrounding environment; and second, to reduce the interference of crosswinds on vehicle stability in windy areas, ensuring driving safety. They are made of various materials, including metal and PC panels, and often have a panel-like structure. Through careful design of height, length, and installation methods, they effectively perform their wind-blocking and sound-insulating functions.

[0003] Traditional windshields typically withstand wind loads rigidly but lack cushioning components, making them highly susceptible to root breakage under strong gusts, which poses a threat to road safety. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent windshield that can automatically adjust according to the crosswind intensity on highways, in order to solve the problem that traditional windshields in the above-mentioned background art usually rigidly resist wind loads, lack buffer structural components, and are very prone to root breakage under strong gusts.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent windbreak screen that can automatically adjust according to the crosswind intensity of a highway, comprising a baffle and brackets fixed on both sides of the baffle; Each of the two brackets has a support at its lower end, and a fixing ring is fixed to the upper front of the support. A glass is fixed to the middle of the lower side of the baffle, and a fixing seat is fixed to the middle of the upper and lower ends of the glass at the position of the back side of the baffle. A sleeve is fixed in the middle of the upper side of the lower fixing seat, and a rotating shaft is movably connected in the middle of the lower side of the upper fixing seat. A fixing circular plate is fixed at the connection between the lower end of the rotating shaft and the inner side of the sleeve. A return spring is provided in the middle inner side of the sleeve. Several fixing frames are fixedly arranged in an equidistant array from top to bottom on the lower rear side of the baffle. Several fixing blocks are fixedly arranged in an equidistant array on the left and right sides of the rear side of the fixing frames. An adjustment plate is provided on the lower front side of the several fixing blocks.

[0006] Preferably, the outer side of the rotating shaft and the front side of the adjusting plate are respectively provided with serrations, and several adjusting plates are connected to the rotating shaft by means of serration meshing connection.

[0007] Preferably, the upper and lower ends of the reset spring are fixedly connected to the lower side of the fixed circular plate and the upper side of the fixed base, respectively.

[0008] Preferably, a slider is provided at the lower front side of the fixed block and the connection point with the adjusting plate. The slider is connected to the adjusting plate by a sliding connection. A groove is provided at the connection point between the inner side of the adjusting plate and the slider. The adjusting plate can move on several sliders through the groove.

[0009] Preferably, the rotating shaft can rotate within the upper fixed seat and the sleeve. When the rotating shaft rotates, the external saw teeth can drive several adjusting plates to move.

[0010] Preferably, arc-shaped guide plates are vertically fixed at both ends of the adjustment plate, and the directions of the arc-shaped guide plates at the left and right ends are opposite. Multiple arc-shaped plates are fixed on the rear exterior of the adjustment plate.

[0011] Preferably, fixing bolts are threaded at the four corners of the lower side of the support, and several drainage holes are equidistantly arranged inside the upper side of the baffle.

[0012] Compared with the prior art, the present invention provides an intelligent windshield that can automatically adjust according to the crosswind intensity on highways, and has the following beneficial effects: 1. This invention adopts a passive triggering mechanism based on the principle of fluid mechanics. It utilizes the differentiated force of the crosswind on the arc-shaped guide plates with opposite directions on both sides of the regulating plate to directly convert wind energy into mechanical energy that drives the regulating plate to move laterally. This mechanical energy is then converted into rotational potential energy of the shaft through gear and rack transmission. This solves the problem of existing intelligent windbreak screens relying on power supply, sensors, and electronic control systems. In harsh outdoor environments such as highways, this device can still work stably, greatly reducing maintenance costs and failure rates.

[0013] 2. Traditional windbreaks typically withstand wind loads rigidly, making them highly susceptible to root breakage under strong gusts. This invention, through the lateral movement of the adjusting plate and the compression and return spring of the rotating shaft, converts the rigid, instantaneous impact force of the airflow into the elastic potential energy of the spring. This buffering mechanism effectively reduces the peak shear force of the instantaneous strong wind on the main body of the windbreak, the support frame, and the foundation bolts, providing significant load-bearing protection and thus greatly extending the service life of the overall windbreak structure.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present invention provides an intelligent windshield that can automatically adjust according to the crosswind intensity of a highway. Its main frame includes a main baffle 7 set on the front side, and vertical support brackets 1 are fixed on the left and right sides of the baffle 7 to ensure the stability of the overall structure.

[0021] In order to securely install the windshield screen on the highway roadbed or guardrail, each bracket 1 is provided with a stable support 2 at its lower end. The support 2 has screw holes at the four corners of its lower side and is anchored to the ground or base by screwing in the matching fixing bolts 5. In addition, in order to facilitate hoisting or connection of other auxiliary facilities, a fixing ring 4 is welded or cast on the upper front of the support 2.

[0022] The upper part of the baffle 7 is designed as a fixed ventilation structure with multiple rows of perforations 3 evenly spaced on its surface. Under normal wind conditions, airflow can pass through these perforations 3, reducing the wind load on the baffle.

[0023] A piece of transparent or semi-transparent glass 6 (or other high-strength transparent material, which is not specifically limited here) is fixedly embedded in the middle of the lower half of the baffle 7 to maintain a clear view.

[0024] like Figure 1 as well as Figure 4 As shown, a mounting base 8 is fixedly installed at the middle position on the upper and lower end frames of the rear area of ​​glass 6. These two mounting bases 8 provide reference points for rotational movement.

[0025] Between the upper and lower fixed seats 8, a rotating shaft 10 is vertically and movably connected. Specifically, the upper end of the rotating shaft 10 is inserted into the bearing hole of the upper fixed seat 8 and can rotate freely; the lower end of the rotating shaft 10 passes through the sleeve 9 fixed on the lower fixed seat 8.

[0026] To achieve the reset function, a fixed circular plate 17 is fixedly sleeved on the section of the rotating shaft 10 inside the sleeve 9. A reset spring 16 is provided in the hollow cavity inside the sleeve 9. The reset spring 16 is sleeved on the outside of the rotating shaft 10, with its lower end fixedly connected to the lower side of the fixed circular plate 17 and its upper end fixedly connected to the upper inner end face of the sleeve 9 or the lower fixed seat 8. When the rotating shaft 10 rotates relative to the fixed seat 8, the reset spring 16 is twisted and generates elastic potential energy. When the external force disappears, the spring releases the potential energy and causes the rotating shaft 10 to reset.

[0027] To support the translation component, multiple horizontal fixing brackets 14 are arranged parallel from top to bottom on the lower rear side of the baffle 7. On the rear side of each fixing bracket 14, several fixing blocks 15 are fixed in an equidistant array along the left and right direction.

[0028] Below the front side of several rows of fixed blocks 15, multiple layers of adjusting plates 11 are suspended. The adjusting plates 11 are slidably connected to the fixing structure; specifically, a slider 18 is provided below the front side of the fixed blocks 15 (clearly shown in...). Figure 4 (As shown in the schematic diagram of the slider), a transverse groove is provided on the inner side of the adjusting plate 11 at the corresponding position to cooperate with the slider 18. After the adjusting plate 11 is engaged with the slider 18, it can only move horizontally left and right along the direction of the groove, and cannot fall off forward, backward or up and down.

[0029] The transmission mechanism adopts the gear and rack meshing principle. Vertical serrations are machined on the outer cylindrical surface of the rotating shaft 10, and corresponding horizontal serrations are also machined in the middle of the front surface of each layer of adjustment plate 11. Several adjustment plates 11 are always meshed with the serrations on the outer side of the rotating shaft 10 through the serrations on their front sides.

[0030] When the shaft 10 rotates, it drives all the adjusting plates 11 to move horizontally to the left or right in sync through the meshing of the teeth; conversely, when the adjusting plates 11 are subjected to horizontal thrust and move horizontally, they will also drive the shaft 10 to rotate in the opposite direction.

[0031] The regulating plate 11 is a key component that directly senses wind force and generates movement. For example... Figure 3 As shown, each adjustment plate 11 has an arc-shaped guide plate 12 welded vertically or integrally formed at its left and right ends. The key point is that the arc-shaped guide plates 12 at the left and right ends of the same adjustment plate 11 have opposite bending directions, forming an asymmetrical response to the airflow.

[0032] In addition, to increase the wind-receiving area and turbulence effect, multiple continuously arranged arc-shaped plates 13 are fixed on the rear side plane of the regulating plate 11.

[0033] This device is installed on both sides of the highway. In the absence of wind or a light breeze, the return spring 16 is in an initial equilibrium state, and the rotating shaft 10 and the adjusting plate 11 are in the preset initial positions.

[0034] When strong crosswinds occur on the highway, the airflow passes through the area below the baffle 7 and impacts the adjustment plate 11 assembly behind it.

[0035] A strong crosswind acts on the arc-shaped guide plates 12 at both ends of the regulating plate 11, which are oriented in opposite directions, and on the arc-shaped plate 13 at the rear. Because the arc-shaped guide plates 12 at both ends are oriented in opposite directions, the airflow generates an unbalanced horizontal component force at the left and right ends of the regulating plate 11 (for example, one end experiences greater wind resistance, while the other end experiences less guiding force), thereby generating a net horizontal thrust on the regulating plate 11 as a whole.

[0036] Under the action of the horizontal thrust, the adjusting plate 11 slides horizontally along the slider 18 on the fixed block 15. Because the adjusting plate 11 and the rotating shaft 10 have a sawtooth meshing relationship, the horizontal movement of the adjusting plate 11 forces the rotating shaft 10 to overcome the resistance of the return spring 16 and rotate. As the wind force increases, the horizontal displacement of the adjusting plate 11 increases, the rotation angle of the rotating shaft 10 increases, and the energy stored by the torsional deformation of the return spring 16 also increases. This process converts the rigid impact energy of the wind into the elastic potential energy of the spring, playing a role in buffering and dissipating energy. Simultaneously, the change in position of the adjusting plate 11 and its own arc-shaped structure also change the direction and state of the airflow passing through the area, playing a role in turbulence and dispersing wind force, thereby reducing the instantaneous impact of crosswinds on road vehicles. When the crosswind intensity weakens or disappears, the horizontal wind thrust acting on the adjusting plate 11 decreases. At this time, the elastic potential energy stored in the return spring 16 is released, generating a restoring torque that drives the rotating shaft 10 to rotate in the opposite direction and reset. The rotation of the rotating shaft 10 then drives the adjusting plate 11 to slide in the opposite direction through gear meshing until it returns to the initial equilibrium position, waiting for the next wind impact.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
