Description

Technical Field

[0001] The invention relates to the technical field of highway sound insulation, and more specifically to an energy-saving and environment-friendly highway sound insulation barrier. Background Art

[0002] A highway sound barrier is a device used to isolate the noise diffusion caused by high-speed vehicles during driving. Usually, the sound barrier is made of polymer materials, glass materials or metal materials. Some guide holes can be set on its surface to guide the airflow, thereby further reducing noise.

[0003] The sound barrier mainly reduces noise by hindering the transmission of sound waves. The sound barrier is installed outdoors, which may cause damage to the sound barrier in extreme outdoor environments. For example, in windy weather or heavy rain, the sound barrier has a large force-bearing area, and strong winds often have a strong impact on the sound barrier, causing damage to the sound barrier. Based on this, in the prior art, such as the sound barrier disclosed in publication number CN111945593B, the sound barrier can be rotated through the design of the mechanism, so that the wind passes through one side of the sound barrier, reducing the direct impact of the wind on the sound barrier. The latter has also improved it by using a motor to drive the rotation of the sound barrier.

[0004] However, the above technical designs all have a problem. The weather resistance of the canvas of the sound insulation barrier disclosed in publication number CN111945593B is poor, and it is easy to age and be damaged outdoors. At the same time, the rotation driven by the motor is greatly limited in outdoor use scenarios, and is not conducive to cost and maintenance.

[0005] Moreover, making the sound insulation barrier rotatable will reduce the sound insulation effect, because multiple groups of sound insulation barriers cannot be seamlessly or directly connected and fixed, otherwise it will affect the rotation of the sound insulation barrier.

[0006] Therefore, the present invention contemplates designing an energy-saving and environmentally friendly highway noise barrier that does not rely on electricity and can protect the noise barrier itself in severe weather.

[0007] In view of this, we propose an energy-saving and environmentally friendly highway noise barrier. Summary of the invention

[0015] Furthermore, the liquid flow-blocking mechanism comprises a T-shaped conduit connected to the lower end of the cylinder, the lower end of the T-shaped conduit is connected to a first air bag, the lower end of the first air bag is fixedly connected to a lower support sheet, the lower end of the lower support sheet is fixedly connected to a second connecting rod, the lower end of the second connecting rod is fixedly connected to a blade, and a through-flow hole is opened on the inner side of the blade;

[0016] A cavity for storing water is provided inside the second plate body, and a drainage port is provided on one side of the cavity. The drainage port is connected to the through-flow hole in a windless state or a state with low wind force, and the drainage port is disconnected from the through-flow hole under the action of strong wind force.

[0017] Furthermore, a magnet B is provided on the other side of the second airbag opposite to the third connecting rod, and the magnet B is magnetically attracted to the third connecting rod.

[0018] Furthermore, the material of the third connecting rod may be a polymer nylon material or a metal material.

[0025] Beneficial Effects

[0026] The effect of the present invention is that in windy weather, the rotation of the fan drives the inflation structure to fill the air bag with gas, so that the air bag is inflated, thereby pushing the first plate body to deflect from the second plate body and form a certain angle with the second plate body, thereby guiding the airflow downward to pass through between the bottom plates, reducing the pressure of wind on the isolation barrier;

[0027] At the same time, in the case of more severe conditions, such as strong winds and heavy rain, the rain is driven by the wind to hit the surface of the first plate, and even some small objects, such as branches, will be driven to hit the plate surface. First, the first plate will rebound after being hit, and the air bag will buffer the impact and discharge the gas in the air bag through the vent hole. The impact will only accelerate the rate of gas discharge without causing gas damage, which can effectively buffer the impact. At the same time, through the design of the back structure of the second plate, the internal cavity of the second plate can be semi-sealed in the case of strong winds, so that rainwater cannot be discharged after entering, which can increase the weight of the barrier, thereby preventing it from being blown down by the wind, and the internal water storage can buffer the impact to a certain extent;

[0028] At the same time, the design of the present invention can achieve filtering in general situations, that is, when the wind force is small, the speed at which the air bag inflates is the same as the exhaust rate, and the first plate body will not be ejected, nor will the inner cavity of the second plate body be semi-sealed.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] See also Figure 1-9 , the present invention provides a technical solution:

[0048] An energy-saving and environmentally friendly highway sound barrier comprises a first plate body 1 and a second plate body 2, wherein the lower end of the first plate body 1 is rotatably connected to the second plate body 2, and the upper end of the first plate body 1 and the upper end of the second plate body 2 are connected and separated via a pop-up mechanism; a gas input end of the pop-up mechanism is connected to an energy conversion mechanism that converts wind energy into kinetic energy, and the energy conversion mechanism drives an air cylinder structure to blow gas into the pop-up mechanism and a liquid flow-blocking mechanism through kinetic energy; the liquid flow-blocking mechanism controls the closure and circulation of the bottom of a cavity arranged inside the second plate body 2 by adjusting the amount of air injected.

[0049] It can be understood that first of all, we need to guide the strong wind so that it cannot form a vertical collision with the sound insulation barrier, and at the same time, the first plate body 1 is rotatably connected to the lower ends of the second plate body 2, and the upper end can be opened and closed, so that an angle can be formed between the first plate body 1 and the second plate body 2, so that the sound insulation barrier cannot form a vertical collision, and the wind is guided to flow through the lower ends of the first plate body and the second plate body by forming an angle to reduce the impact of wind force, but at the same time, the feasibility of the angle between the first plate body and the second plate body is realized. We need to think about how to control the formation of the angle, so at the upper ends of the first plate body and the second plate body, we install a pop-up mechanism at the inner side of the second plate body near the upper end to make the pop-up mechanism After blowing air, the ejection mechanism can push the first plate body away, thereby completing the separation of the first plate body and the second plate body and forming a certain angle; at the same time, the blowing of gas needs to be achieved through the structure of the air cylinder, and the power source of the air cylinder is provided by the energy conversion mechanism, which converts wind force into kinetic energy to drive the air cylinder to inflate; and the output end of the air cylinder is connected to the input end of the ejection mechanism and the input end of the liquid flow resistance mechanism through a T-shaped conduit, respectively, so that while realizing the ejection of the first plate body, it can also realize the pushing of the liquid flow resistance mechanism to form a semi-closed cavity inside the second plate body 2, so that rainwater can remain inside the cavity to increase the deadweight and air impact capacity of the second plate body.

[0050] An energy-saving and environmentally friendly highway noise barrier, the pop-up mechanism includes a third connecting rod 102 with one end rotatably connected to the upper end of a first plate body 1, the other end of the third connecting rod 102 is rotatably connected to a magnet A103, and a second air bag 107 that can be ventilated and expanded is provided on one side of the magnet A103; the second air bag 107 is connected to a conduit 105, and one end of the conduit 105 is connected to a T-shaped conduit 19;

[0051] It needs to be explained that air is continuously blown into the second air bag 107 through one end of the T-tube 19, and the expansion of the second air bag 107 pushes the magnet A103, the magnet A103 pushes the third connecting rod, and the third connecting rod pushes the first plate body 1 to pop out, and the two ends of the third connecting rod need to be rotationally connected to the first plate body and the magnet A103 respectively to ensure the smooth ejection of the first plate body.

[0052] It can also be understood that the energy conversion mechanism includes a support frame 3 fixedly connected to the upper end of the second plate body 2, the upper end of the support frame 3 is fixedly connected to the outer side of the movable bearing 4, the inner side of the movable bearing 4 is fixedly connected to the rotating rod 5, the inner side and the outer side of the movable bearing 4 can rotate relative to each other, one end of the rotating rod 5 is coaxially fixedly connected to the fan blade 6, the other end of the rotating rod 5 is coaxially fixedly connected to the follower plate 7, one side of the follower plate 7 is fixedly connected to the first connecting member 8, the first connecting member 8 is rotatably connected to one end of the first movable rod 9, the other end of the first movable rod 9 is rotatably connected to the second connecting member 10, the The second connecting member 10 is rotatably connected to one end of the connecting block 11 at the same time, and the other end of the connecting block 11 is fixedly connected to the sliding platform 12. The interior of the sliding platform 12 is slidably connected to the guide rod 13. Both ends of the guide rod 13 are fixedly connected to fixing members 14, and the fixing members 14 are fixedly connected to the inner wall of the first protective frame 25. In windy weather, the wind drives the rotation of the fan blades 6, and the fan blades 6 drive the follower plate 7 to rotate. The follower plate 7 is driven by the combined structure of the first connecting member 8, the first movable rod 9, the second connecting member 10, the connecting block 11, the sliding platform 12 and the guide rod 13, so that the sliding platform 12 reciprocates on the guide rod 13.

[0053] The fixing member 14 is fixedly connected to the inner wall of the first protection frame 25 to provide stable support for the guide rod 13 , thereby ensuring stable sliding of the sliding platform 12 .

[0054] The specific structure of the gas cylinder is as follows: the gas cylinder includes a first connecting rod 15 with one end fixedly connected to the lower end of the sliding platform 12, the other end of the first connecting rod 15 is fixedly connected to one end of a guide plate 16, the other end of the guide plate 16 is fixedly connected to a rubber plug 17, the guide plate 16 and the rubber plug 17 are both arranged inside a cylinder 33, and an air hole 34 is opened at the upper end of the cylinder 33.

[0055] It should be noted that the rubber plug is arc-shaped, and the direction of the arc bending is opposite to the setting direction of the air hole 34. The principle is that when the gas cylinder moves toward the direction away from the air hole 34 through the first connecting rod, the air pressure compresses the rubber plug to expand, so that the inner wall of the rubber plug is close to the inner wall of the cylinder, so that the gas cannot overflow from between the cylinder wall and the rubber plug, thereby pushing the gas into the T-shaped tube, and when the first connecting rod moves toward the direction close to the air hole 34, the rubber plug is bent inward by the air pressure, thereby increasing the gap between the rubber plug and the cylinder wall, and the gas can flow from 34 to the gap between the rubber plug and the bottom of the cylinder, and prepare for the next gas injection;

[0056] The power source of the first connecting rod is to convert wind force into mechanical energy through the energy conversion mechanism, thereby driving the movement of the first connecting rod.

[0057] The liquid flow-blocking mechanism includes a T-tube 19 connected to the lower end of the cylinder 33, the lower end of the T-tube 19 is connected to a first air bag 20, the lower end of the first air bag 20 is fixedly connected to a lower support plate 21, the lower end of the lower support plate 21 is fixedly connected to a second connecting rod 22, the lower end of the second connecting rod 22 is fixedly connected to a blade 23, and a flow hole 24 is opened on the inner side of the blade 23; the interior of the second plate body 2 is provided with a cavity that can be used for storing water, and a drain port 108 is provided on one side of the cavity, the drain port 108 is connected to the flow hole 24 in a windless state or a state with low wind force, and the drain port 108 is disconnected from the flow hole 24 under the action of strong wind force.

[0058] It can be understood that part of the air input by the air cylinder enters the first air bag through the T-shaped tube. As the first air bag 20 expands, it pushes the blade 23 downward, thereby disconnecting the through-hole 24 from the liquid discharge port 108, and the expansion of the second air bag 107 pushes the magnet A103, thereby pushing the first plate body 1 to pop out. At this time, due to the misalignment of the through-hole 24 and the liquid discharge port 108, the cavity inside the second plate body 2 can store water. The specific effects are as follows:

[0059] The popping out of the first plate body 1 forms a backflow angle, and the downward movement of the blade 23 makes the inner cavity of the second plate body 2 form a semi-closed cavity with only the upper end open. Rainwater directly enters the cavity through the filter screen 201 at the upper end, which can increase the dead weight of the cavity and the impact resistance of the second plate body 2, thereby further increasing the wind resistance of the present invention.

[0060] A magnet B104 is arranged on the other side of the second air bag 107 opposite to the third connecting rod 102. The magnet B104 is magnetically attracted to the third connecting rod 102. Through the design of the above structure, when no air is injected into the second air bag 107, the first plate body 1 can be retracted into the inner side of the second plate body 2 by magnetic attraction.

[0061] The material of the third connecting rod 102 can be polymer nylon material or metal material. The polymer nylon material is weather-resistant, high-strength and high-toughness. It should be noted that the structures of nylon material and metal material are both rod structures, which need to have sufficient strength to push open the first plate.

[0062] The magnet A103, magnet B104 and the second air bag 107 are all arranged in the slide grooves arranged on the inner walls on both sides of the second plate body 2, and the slide groove mouth is provided with a blocking plate to prevent the magnet A103, and the upper end of the slide groove is provided with a connecting pipe 106 for connecting to the external inflation, and the setting of the blocking plate prevents the magnet A103 from being pushed out of the slide groove, so that the first plate body 1 loses the pulling force, so that it cannot form a low angle inclination with the second plate body 2, and the lower end of the cylinder 33 is fixedly connected to the upper support plate 18, and a second movable rod 29 and a spring 30 are arranged between the upper support plate 18 and the lower support plate 21, and the two ends of the second movable rod 29 are respectively fixed on the upper support plate 18 and the lower support plate 21, and the spring 30 is sleeved on the outside of the second movable rod 29, and the two ends of the spring 30 are also respectively fixed on the upper support plate 18 and the lower support plate 21.

[0063] It is understandable that, similarly to the recovery of the first plate body 1, when the first air bag 20 is not continuously injected with air, the spring 30 will pull the blade 23 to recover, and the second movable rod 29 plays a guiding role, so that the through-flow hole 24 is connected with the drain port 108 and the drain hole 28 under normal conditions, preventing water from accumulating inside the second plate body 2, causing dirt and breeding of mosquitoes, etc.

[0064] The first air bag 20 and the second air bag 107 are both provided with pressure relief holes, and a pressing sheet 211 is fixedly installed around the pressure relief hole. The pressure relief hole on the first air bag 20 is connected with a pressure relief pipe 32 .

[0065] It is necessary to provide holes on the first air bag 20 and the second air bag 107 for pressure relief to prevent continuous air injection from causing the air bag to explode. It should be noted that the size of the pressure relief hole is small, and its deflation speed under strong wind conditions is much lower than the gas injection speed of the air pump, so the air bag will still inflate. Under normal light wind conditions, due to the low fan blade speed, the gas injection speed of the air pump is consistent with the speed of the deflation hole, and the air bag will not be inflated. Therefore, the present invention will only be triggered in extreme weather.

[0066] The cylinder 33 is located inside the second protective frame 26, and the second protective frame 26 is fixedly connected to the inside with a limit plate 31. The second protective frame 26 limits the movement of the second connecting rod 22, and the cylinder 33 protects the air pump structure. The blade 23 is slidably connected to the inside of the third protective frame 27, and the inner walls on both sides of the third protective frame 27 are provided with drainage holes 28 connected to the drainage port 108. The drainage hole 28 structure protects the blade 23 and cannot hinder the discharge of liquid. The lower end of the second plate body 2 is fixedly installed with a bottom plate 35, and the bottom plate 35 needs to be installed in the soil. Its material is preferably metal to ensure its strength.

[0067] Example 2

[0068] like Fig.10 As shown, the difference from Comparative Example 1 is that in this embodiment, a pressing plate 211 is installed on the shaft hole of the pressure relief hole. The pressing plate 211 is a circular ring made of metal or high-strength material, which can effectively prevent the airbag from being torn from the pressure relief hole due to excessive internal pressure.

[0069] Example 3

[0070] Comparative Example 1 In the present invention, a pressure relief hole can be opened on any one of the first airbag and the second airbag. Since the two airbags are connected, a certain pressure relief effect can be achieved on both airbags through one pressure relief hole.

[0071] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
