Description

Technical Field

[0001] The present invention belongs to the technical field of pavement structures, and in particular relates to a graphene-based self-melting snow pavement structure and a construction method thereof. Background Art

[0002] Snow accumulation on the road can affect vehicle traffic. Furthermore, when vehicles compact the snow, it turns into ice, reducing friction between tires and the snowy road surface. This can easily cause vehicles to slip and roll over, significantly impacting road traffic. Currently, snow removal is typically done manually or by vehicles, both of which are inefficient.

[0003] Chinese patent application CN112878133A discloses a graphene-based self-melting snow pavement structure. The key technical solution addresses the poor conductivity, crack resistance, and durability of existing conductive asphalt, as well as the harsh application environments and short service life of graphene heating films. This improves existing pavements to achieve high snow and ice melting costs and poor results. The graphene-based self-melting snow pavement structure comprises an insulation layer, a graphene-based conductive asphalt layer, a conductive shape memory composite material layer, an insulating asphalt layer, and a surface layer, laid sequentially on the road surface from bottom to top. Multiple electrodes are spaced apart within the graphene-based conductive asphalt layer.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the existing technology uses graphene heating film to heat the road surface. Although it can effectively melt snow, the construction requirements of the graphene heating film are relatively high. It requires a relatively flat installation base surface, and no obvious particles or protrusions are allowed on the base surface. Otherwise, it is easy to cause damage to the graphene heating film. In addition, the graphene heating film is easy to break during the construction process, and the subsequent service life is also relatively low.

[0005] To this end, the present invention provides a graphene-based self-melting snow pavement structure and a construction method thereof. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the graphene-based self-melting snow pavement structure described in the present invention includes a road base layer; the surface of the road base layer is covered with an asphalt layer; a graphene conductive fiber mesh is pre-embedded inside the asphalt layer; a protective box is fixedly connected to the side of the road base layer; a controller and a power storage device are arranged inside the protective box, and the power storage device is connected to the graphene conductive fiber mesh through the controller; a photovoltaic panel is arranged on the side of the road base layer, and the photovoltaic panel is connected to the power storage device.

[0008] The preparation process of the graphene conductive fiber mesh of the present invention is as follows: a layer-by-layer self-assembly method is adopted in combination with a chemical reduction process to uniformly attach graphene nanosheets to the surface of a glass fiber mesh, and overlap with each other to form a conductive layer; the glass fiber mesh is placed in acetone, ultrasonically treated for a period of time at a certain power, taken out and dried to a constant weight, and then immersed in a graphene oxide dispersion. After immersion for a period of time, the glass fiber mesh is taken out and dried to a constant weight for standby use; the glass fiber mesh is then immersed in deionized water and ultrasonically treated for a period of time at a certain power to remove all graphene oxide physically adsorbed on the surface of the glass fiber mesh, and then the glass fiber mesh is taken out and dried to a constant weight for standby use (this process can be repeated multiple times as needed) to obtain a glass fiber mesh loaded with graphene oxide, which is then immersed in a reducing agent solution, reacted at a certain temperature for a period of time, and then taken out and dried to a constant weight (this process can be repeated multiple times as needed) to obtain a graphene conductive fiber mesh.

[0009] The construction requirements of the graphene conductive fiber mesh are relatively low. It only needs to be placed inside the asphalt layer during paving. When snow accumulates on the road surface, the graphene conductive fiber mesh can be powered by the power storage device. The graphene conductive fiber mesh then generates heat and conducts it to the snow through the asphalt layer, heating and melting the snow. The photovoltaic panels can convert light energy into electrical energy and store it in the power storage device for use by the graphene conductive fiber mesh.

[0010] Preferably, one side of the photovoltaic panel is rotatably connected to the roadbed through a rotation pin; a mounting plate is fixedly connected to the side of the roadbed below the photovoltaic panel; a support tube is fixedly connected to the upper side of the mounting plate; a slider is slidably connected to the interior of the support tube; a support rod is fixedly connected to the upper side of the slider; the support rod is slidably connected to the top of the support tube, and the top of the support rod is in contact with the photovoltaic panel; a spring 1 is fixedly connected between the upper side of the slider and the top of the support tube; a contact 1 is fixedly connected to the lower side of the slider; a contact 2 is fixedly connected to the bottom of the support tube; both the contact 1 and the contact 2 are connected to a controller; when snow falls on the surface of the photovoltaic panel and reaches a certain thickness, gravity can drive the photovoltaic panel to deflect downward, and then the slider is pressed down by the support rod, so that the contact 1 and the contact 2 come into contact. At this time, the controller receives an electrical signal and controls the power storage device to supply power to the graphene conductive fiber mesh, so that the present invention can automatically sense the snow state on the road and automatically activate the graphene conductive fiber mesh when the snow reaches a certain thickness, thereby melting the snow without manual activation of the graphene conductive fiber mesh, thereby improving the automation and intelligence of the present invention.

[0011] Preferably, the top end of the support rod is rotatably connected to a roller, and the roller is in contact with the photovoltaic panel; when the photovoltaic panel presses down the support rod, the roller can roll on the lower surface of the photovoltaic panel, so that there is no direct friction between the support rod and the photovoltaic panel, thereby preventing the support rod from scratching the photovoltaic panel and causing damage to the photovoltaic panel.

[0012] Preferably, an electric push rod is pre-embedded inside the roadbed layer, and the electric push rod is in an inclined state (the inclination angle of the photovoltaic panel after deflection downward is the same as the inclination angle of the electric push rod), and the output end of the electric push rod extends to the upper side of the photovoltaic panel and is fixedly connected to a lever; the electric push rod is controlled by a controller; when contact one contacts contact two, the controller controls the electric push rod to extend outward and push the lever to move on the upper side of the photovoltaic panel, thereby pushing the snow on the surface of the photovoltaic panel down along the inclined direction, playing the effect of clearing the snow, preventing the gravity of the snow from acting on the surface of the photovoltaic panel for a long time, causing the photovoltaic panel to be compressed and damaged, and preventing the snow from blocking the photovoltaic panel, resulting in the subsequent inability to convert electrical energy; it is worth noting that after contact one contacts contact two, under the control of the controller, the graphene conductive fiber mesh can continue to work for a period of time to heat the snow, and the electric push rod only extends and retracts once. When the electric push rod contracts, the snow on the surface of the photovoltaic panel has been cleared, and the spring one drives the photovoltaic panel to deflect upward and reset through the slider and the support rod.

[0013] Preferably, a ring-shaped flexible roller is rotatably connected to the outer side of the lever, and the flexible roller is in contact with the surface of the photovoltaic panel; by setting the flexible roller, when the electric push rod pushes the lever to move, the flexible roller can roll on the surface of the photovoltaic panel and push the snow downward, so that there is no direct friction between the lever and the photovoltaic panel, thereby preventing the lever from scratching the photovoltaic panel and causing damage to the photovoltaic panel.

[0014] Preferably, the flexible roller is made of a porous material (which can be porous cotton or other materials); a group of storage bottles are fixedly connected to the side of the roadbed above the flexible roller through a support plate, and salt is added to the storage bottles; a switch assembly is provided at the bottle mouth at the bottom of the storage bottle; the switch assembly is used to control the opening and closing of the storage bottle; the bottle mouth of the storage bottle is opened by the switch assembly, and the salt inside the storage bottle falls down to the surface of the photovoltaic panel, which can accelerate the melting of snow, and part of the salt falls on the surface of the flexible roller and enters the porous structure. After that, the flexible roller can further smear the salt on the surface of the photovoltaic panel during the rolling process on the surface of the photovoltaic panel, melt the remaining snow, and improve the efficiency of snow removal.

[0015] Preferably, the switch assembly includes a guide block slidably connected to the inside of the bottle mouth of the storage bottle; a guide hole is provided on the upper side of the guide block; an oblique opening is provided on the side of the guide block, and the oblique opening is connected to the guide hole; a spring is fixedly connected between the upper side of the guide block and the storage bottle; one end of the guide block extending outside the storage bottle is fixedly connected to a connecting plate; the lower side of the support plate is fixedly connected to the air pipe; the upper side of the connecting plate is fixedly connected to a movable rod, and the movable rod is slidably and sealedly connected to the inside of the air pipe; the slider is slidably and sealedly connected to the support tube; the bottom of the support tube is connected to the air pipe through a conduit; the photovoltaic panel is connected through When the support rod presses the slider, the slider squeezes the air at the bottom of the support tube into the inside of the trachea through the conduit, pushing the movable rod to move downward, and then the movable rod drives the guide block to move downward through the connecting plate, so that the oblique opening is exposed. At this time, the salt inside the storage bottle can be discharged through the guide hole and the oblique opening. When the snow on the surface of the photovoltaic panel is cleared, the photovoltaic panel drives the slider to reset upward, and the air in the trachea returns to the inside of the support tube through the conduit, and the spring 2 drives the guide block to reset upward and re-seal the storage bottle. This structure can realize the automatic opening and closing of the storage bottle, further improving the automation and intelligence level of the present invention.

[0016] Preferably, a pressure plate is fixedly connected to the side of the asphalt layer by an expansion bolt; a side plate is fixedly connected to the upper side of the road base near the side of the asphalt layer; a spring three is arranged between the pressure plate and the side plate; when the asphalt layer is crushed by a heavy-loaded vehicle or in high temperature weather, the asphalt layer may cause lateral expansion. By arranging the pressure plate, the side plate and the spring three, when the asphalt layer expands laterally, the spring three is compressed and can exert a reaction force on the asphalt layer, thereby hindering the expansion of the asphalt layer and reducing the problem of cracking of the asphalt layer caused by expansion. At the same time, it can reduce the problem of displacement and tearing between the asphalt layer and the road base, and the problem of cracks between the two.

[0017] Preferably, a waterproof cloth is fixedly connected between the bottom of the pressing plate and the bottom of the side plate; a group of through holes are evenly distributed on the bottom of the side plate near the top of the waterproof cloth; if the asphalt layer and the road base layer are displaced and torn, and cracks are generated between the two, moisture will easily enter the cracks, which will cause the cracks to become larger and larger, destroying the structure between the road base layer and the asphalt layer. By setting a waterproof cloth to seal the bottom of the pressing plate and the side plate, the above problem can be avoided, and the accumulated water between the pressing plate and the side plate can be discharged outward through the through holes.

[0021] S3: Install the protection box, controller, power storage device and photovoltaic panel on the side of the roadbed and connect them with each other through wires.

[0022] The beneficial effects of the present invention are as follows:

The construction requirements of the graphene conductive fiber mesh are relatively low. The graphene conductive fiber mesh only needs to be placed inside the asphalt layer during paving. When snow accumulates on the road surface, the graphene conductive fiber mesh can be powered by a power storage device. The graphene conductive fiber mesh then generates heat and conducts it to the snow through the asphalt layer, heating and melting the snow. The photovoltaic panel can convert light energy into electrical energy, which is stored in the power storage device for use by the graphene conductive fiber mesh.

[0024] 2. The present invention describes a graphene-based self-melting snow pavement structure and a construction method thereof. When it snows, when the snow accumulated on the surface of the photovoltaic panel reaches a certain thickness, gravity can drive the photovoltaic panel to deflect downward, and then the slider is pressed down by the support rod, so that contact one and contact two come into contact. At this time, the controller receives an electrical signal and controls the power storage device to supply power to the graphene conductive fiber mesh, so that the present invention can automatically sense the snow accumulation status on the road and automatically activate the graphene conductive fiber mesh when the snow reaches a certain thickness, thereby melting the snow without the need for manual activation of the graphene conductive fiber mesh, thereby improving the automation and intelligence level of the present invention.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1:

[0035] like Figures 1 to 4 As shown, a graphene-based self-melting snow pavement structure described in an embodiment of the present invention includes a road base layer 1; the surface of the road base layer 1 is covered with an asphalt layer 2; a graphene conductive fiber mesh 3 is pre-embedded inside the asphalt layer 2; a protective box 4 is fixedly connected to the side of the road base layer 1; a controller and a power storage device are provided inside the protective box 4, and the power storage device is connected to the graphene conductive fiber mesh 3 through the controller; a photovoltaic panel 5 is provided on the side of the road base layer 1, and the photovoltaic panel 5 is connected to the power storage device.

[0036] The preparation process of the graphene conductive fiber mesh 3 in the present invention is as follows: a layer-by-layer self-assembly method is adopted, and a chemical reduction process is used to uniformly attach graphene nanosheets to the surface of the glass fiber mesh, and overlap each other to form a conductive layer; the glass fiber mesh is placed in acetone, ultrasonically treated at a certain power for a period of time, taken out and dried to constant weight, and then immersed in a graphene oxide dispersion. After immersion for a period of time, it is taken out and dried to constant weight for standby use; the glass fiber mesh is then immersed in deionized water and ultrasonically treated at a certain power for a period of time to remove all graphene oxide physically adsorbed on the surface of the glass fiber mesh, and then the glass fiber mesh is taken out and dried to constant weight for standby use (this process can be repeated multiple times as needed) to obtain a glass fiber mesh loaded with graphene oxide, which is then immersed in a reducing agent solution, reacted at a certain temperature for a period of time, and then taken out and dried to constant weight (this process can be repeated multiple times as needed) to obtain a graphene conductive fiber mesh 3.

[0037] The construction requirements of the graphene conductive fiber mesh 3 are relatively low. It only needs to be placed inside the asphalt layer 2 during paving. When snow accumulates on the road surface, the graphene conductive fiber mesh 3 can be powered by the power storage device. Then the graphene conductive fiber mesh 3 generates heat and conducts it to the snow through the asphalt layer 2, heating and melting the snow. The photovoltaic panel 5 can convert light energy into electrical energy and store it in the power storage device for use by the graphene conductive fiber mesh 3.

[0038] One side of the photovoltaic panel 5 is rotatably connected to the roadbed 1 through a turn pin; a mounting plate 6 is fixedly connected to the side of the roadbed 1 below the photovoltaic panel 5; a support tube 7 is fixedly connected to the upper side of the mounting plate 6; a slider 8 is slidably connected inside the support tube 7; a support rod 9 is fixedly connected to the upper side of the slider 8; the support rod 9 is slidably connected to the top of the support tube 7, and the top of the support rod 9 is in contact with the photovoltaic panel 5; a spring 10 is fixedly connected between the upper side of the slider 8 and the top of the support tube 7; a contact 11 is fixedly connected to the lower side of the slider 8; a contact 2 12 is fixedly connected to the bottom of the support tube 7; the contact 1 Both contact 11 and contact 2 12 are connected to the controller; when it snows, after the snow accumulated on the surface of the photovoltaic panel 5 reaches a certain thickness, the photovoltaic panel 5 can be driven downward by gravity, and then the slider 8 is pressed down by the support rod 9, so that contact 1 11 contacts contact 2 12. At this time, the controller receives an electrical signal and controls the power storage device to supply power to the graphene conductive fiber mesh 3, so that the present invention can automatically sense the snow state on the road and automatically start the graphene conductive fiber mesh 3 when the snow reaches a certain thickness, thereby melting the snow without manually starting the graphene conductive fiber mesh 3, thereby improving the automation and intelligence level of the present invention.

[0039] The top end of the support rod 9 is rotatably connected to a roller 13, and the roller 13 is in contact with the photovoltaic panel 5; when the photovoltaic panel 5 presses down the support rod 9, the roller 13 can roll on the lower surface of the photovoltaic panel 5, so that there is no direct friction between the support rod 9 and the photovoltaic panel 5, thereby preventing the support rod 9 from causing scratches on the photovoltaic panel 5 and causing damage to the photovoltaic panel 5.

[0040] An electric push rod 14 is embedded in the roadbed 1, and the electric push rod 14 is in an inclined state (the inclination angle of the photovoltaic panel 5 after deflection is the same as the inclination angle of the electric push rod 14). The output end of the electric push rod 14 extends to the upper side of the photovoltaic panel 5 and is fixedly connected to the lever 15; the electric push rod 14 is controlled by a controller; when the contact 11 contacts the contact 2 12, the controller controls the electric push rod 14 to extend outward and push the lever 15 to move on the upper side of the photovoltaic panel 5, thereby pushing the snow on the surface of the photovoltaic panel 5 down along the inclined direction, achieving the effect of clearing the snow and preventing It can prevent the gravity of the accumulated snow from acting on the surface of the photovoltaic panel 5 for a long time, causing the photovoltaic panel 5 to be damaged by pressure, and can also prevent the accumulated snow from blocking the photovoltaic panel 5, causing the problem of subsequent inability to convert electrical energy; it is worth noting that after contact 11 contacts contact 2 12, under the control of the controller, the graphene conductive fiber mesh 3 can continue to work for a period of time to heat the accumulated snow, and the electric push rod 14 only extends and retracts once. When the electric push rod 14 contracts, the snow on the surface of the photovoltaic panel 5 has been cleared, and the spring 10 drives the photovoltaic panel 5 to deflect upward and reset through the slider 8 and the support rod 9.

[0041] The outer side of the lever 15 is rotatably connected to a ring-shaped flexible roller 16, and the flexible roller 16 is in contact with the surface of the photovoltaic panel 5; by providing the flexible roller 16, when the electric push rod 14 pushes the lever 15 to move, the flexible roller 16 can roll on the surface of the photovoltaic panel 5 and push the snow downward, so that there is no direct friction between the lever 15 and the photovoltaic panel 5, thereby preventing the lever 15 from scratching the photovoltaic panel 5 and causing damage to the photovoltaic panel 5.

[0042] The flexible roller 16 is made of porous material (it can be porous cotton or other materials); a group of storage bottles 18 are fixedly connected to the side of the roadbed 1 above the flexible roller 16 through a support plate 17, and salt is added to the storage bottles 18; a switch assembly is provided at the bottle mouth at the bottom of the storage bottle 18; the switch assembly is used to control the opening and closing of the storage bottle 18; the bottle mouth of the storage bottle 18 is opened by the switch assembly, and then the salt inside the storage bottle 18 falls down to the surface of the photovoltaic panel 5, which can accelerate the melting of snow, and part of the salt falls on the surface of the flexible roller 16 and enters the porous structure. After that, the flexible roller 16 can further apply salt to the surface of the photovoltaic panel 5 during the rolling process on the surface of the photovoltaic panel 5, melt the remaining snow, and improve the efficiency of snow removal.

[0043] The switch assembly includes a guide block 19 that is slidably connected to the inside of the bottle mouth of the storage bottle 18; a guide hole 20 is opened on the upper side of the guide block 19; an oblique opening 21 is opened on the side of the guide block 19, and the oblique opening 21 is connected to the guide hole 20; a spring 22 is fixedly connected between the upper side of the guide block 19 and the storage bottle 18; the end of the guide block 19 extending outside the storage bottle 18 is fixedly connected to a connecting plate 23; the lower side of the support plate 17 is fixedly connected to the air pipe 24; the upper side of the connecting plate 23 is fixedly connected to a movable rod 25, and the movable rod 25 is slidably and sealedly connected to the inside of the air pipe 24; the slider 8 and the support tube 7 are slidably and sealedly connected; the bottom of the support tube 7 is connected to the air pipe 24 through a conduit 26; the photovoltaic panel 5 When the slider 8 is pressed down by the support rod 9, the slider 8 squeezes the air at the bottom of the support tube 7 into the inside of the trachea 24 through the conduit 26, pushing the movable rod 25 to move downward, and then the movable rod 25 drives the guide block 19 to move downward through the connecting plate 23, so that the oblique opening 21 is exposed. At this time, the salt inside the storage bottle 18 can be discharged through the guide hole 20 and the oblique opening 21. When the snow on the surface of the photovoltaic panel 5 is cleared, the photovoltaic panel 5 drives the slider 8 to reset upward, and the air in the trachea 24 returns to the inside of the support tube 7 through the conduit 26, and the spring 22 drives the guide block 19 to reset upward and re-seal the storage bottle 18. This structure can realize the automatic opening and closing of the storage bottle 18, further improving the automation and intelligence level of the present invention.

[0044] Example 2:

[0045] like Figure 5 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a pressure plate 28 is fixedly connected to the side of the asphalt layer 2 by an expansion bolt 27; a side plate 29 is fixedly connected to the upper side of the road base layer 1 near the side of the asphalt layer 2; a spring three 30 is provided between the pressure plate 28 and the side plate 29; when the asphalt layer 2 is crushed by a heavy-loaded vehicle or in high temperature weather, the asphalt layer 2 may expand laterally. By providing the pressure plate 28, the side plate 29 and the spring three 30, when the asphalt layer 2 expands laterally, the spring three 30 is compressed and can exert a reaction force on the asphalt layer 2, thereby hindering the expansion of the asphalt layer 2 and reducing the problem of cracking of the asphalt layer 2 caused by expansion. At the same time, it can reduce the displacement and tearing between the asphalt layer 2 and the road base layer 1, and the problem of cracks between the two.

[0046] A waterproof cloth 31 is fixedly connected between the bottom of the pressing plate 28 and the bottom of the side plate 29; a group of through holes 32 are evenly distributed on the bottom of the side plate 29 near the top of the waterproof cloth 31; if the asphalt layer 2 and the road base layer 1 are displaced and torn, and cracks are generated between the two, moisture will easily enter the cracks, which will cause the cracks to become larger and larger, destroying the structure between the road base layer 1 and the asphalt layer 2. By providing a waterproof cloth 31 to seal the bottom of the pressing plate 28 and the side plate 29, the above problem can be avoided, and the accumulated water between the pressing plate 28 and the side plate 29 can be discharged outward through the through holes 32.

[0047] like Figure 6 As shown, a construction method of a graphene-based self-melting snow pavement structure is provided. The method is used to pave the above-mentioned graphene-based self-melting snow pavement structure, comprising the following steps:

[0048] S1: Clear the surrounding vegetation, level the ground, and use sand, gravel, and earth to lay the road base 1;

[0049] S2: The asphalt layer 2 is laid in layers. First, a bottom layer of asphalt is laid on the surface of the road base 1. The graphene conductive fiber mesh 3 is placed on the bottom layer of asphalt. Then, a middle layer of asphalt is laid. The asphalt is vibrated to penetrate into the graphene conductive fiber mesh 3. Finally, the top layer of asphalt is laid.

[0050] S3: Install the protection box 4, controller, power storage device and photovoltaic panel 5 on the side of the roadbed 1 and connect them to each other through wires.

[0051] Working principle: When snow accumulates on the road, the graphene conductive fiber mesh 3 can be powered by the power storage device, and then the graphene conductive fiber mesh 3 generates heat and conducts it to the snow through the asphalt layer 2, heating and melting the snow, and the photovoltaic panel 5 can convert light energy into electrical energy, which is stored in the power storage device for use by the graphene conductive fiber mesh 3; when it snows, when the snow on the surface of the photovoltaic panel 5 reaches a certain thickness, it can drive the photovoltaic panel 5 to deflect downward by gravity, and then press the slider 8 down through the support rod 9, so that the contact 1 11 contacts the contact 2 12. At this time, the controller receives the electrical signal and controls the power storage device to be graphene The conductive fiber mesh 3 is powered, so that the present invention can automatically sense the snow state on the road and automatically start the graphene conductive fiber mesh 3 when the snow reaches a certain thickness, thereby melting the snow. There is no need to manually start the graphene conductive fiber mesh 3, which improves the automation and intelligence of the present invention. In the process of the photovoltaic panel 5 pressing the support rod 9, the roller 13 can roll on the lower surface of the photovoltaic panel 5, so that there is no direct friction between the support rod 9 and the photovoltaic panel 5, thereby preventing the support rod 9 from scratching the photovoltaic panel 5 and causing damage to the photovoltaic panel 5. When the contact 1 11 contacts the contact 2 12, the controller controls the electric push rod 14 The electric push rod 14 extends outward and pushes the lever 15 to move on the upper side of the photovoltaic panel 5, thereby pushing the snow on the surface of the photovoltaic panel 5 down in the inclined direction, playing the role of clearing the snow, preventing the gravity of the snow from acting on the surface of the photovoltaic panel 5 for a long time, causing the photovoltaic panel 5 to be compressed and damaged, and preventing the snow from blocking the photovoltaic panel 5, resulting in the subsequent inability to convert electrical energy. When the electric push rod 14 is retracted, the snow on the surface of the photovoltaic panel 5 has been cleared, and the spring 10 drives the photovoltaic panel 5 to deflect upward and reset through the slider 8 and the support rod 9; by setting the flexible roller 16, the electric push rod 14 pushes the lever 15 to move, and the flexible roller 16 can roll on the surface of the photovoltaic panel 5 and push the accumulated snow downward, so that there is no direct friction between the lever 15 and the photovoltaic panel 5, thereby preventing the lever 15 from scratching the photovoltaic panel 5 and causing damage to the photovoltaic panel 5; the bottle mouth of the storage bottle 18 is opened by the switch component, and then the salt inside the storage bottle 18 falls downward on the surface of the photovoltaic panel 5, which can accelerate the melting of the snow, and part of the salt falls on the surface of the flexible roller 16 and enters the porous structure. After that, the flexible roller 16 can further apply salt to the surface of the photovoltaic panel 5 during the process of rolling on the surface of the photovoltaic panel 5, melting the remaining snow and improving the snow removal efficiency;When the photovoltaic panel 5 presses the slider 8 downward through the support rod 9, the slider 8 squeezes the air at the bottom of the support tube 7 into the inside of the air pipe 24 through the conduit 26, pushing the movable rod 25 to move downward, and then the movable rod 25 drives the guide block 19 to move downward through the connecting plate 23, so that the oblique opening 21 is exposed. At this time, the salt inside the storage bottle 18 can be discharged through the guide hole 20 and the oblique opening 21. When the snow on the surface of the photovoltaic panel 5 is cleared, the photovoltaic panel 5 drives the slider 8 to reset upward, and the air in the air pipe 24 returns to the inside of the support tube 7 through the conduit 26, and the spring 22 drives the guide block 19 to reset upward and re-seal the storage bottle 18. This structure can realize the automatic opening and closing of the storage bottle 18, further improving the automation and intelligence level of the present invention; when the asphalt layer 2 is crushed by a heavy-loaded vehicle or in hot weather, it may cause The asphalt layer 2 expands laterally. By providing a pressure plate 28, side plates 29, and spring 30, when the asphalt layer 2 expands laterally, the compressed spring 30 exerts a reaction force on the asphalt layer 2, thereby hindering the expansion of the asphalt layer 2 and reducing the problem of cracking in the asphalt layer 2 caused by expansion. This also reduces the problem of displacement and tearing between the asphalt layer 2 and the roadbed layer 1, which can cause cracks to form between them. If the asphalt layer 2 and the roadbed layer 1 shift and tear, and cracks form between them, moisture can easily enter the cracks, causing them to grow larger and damaging the structure between the roadbed layer 1 and the asphalt layer 2. This problem can be avoided by providing a waterproof cloth 31 to seal the bottom of the pressure plate 28 and side plates 29. Water accumulated between the pressure plate 28 and side plates 29 can be discharged outward through the through holes 32.
