Description

Technical Field

[0001] This utility model relates to the field of road marking technology, specifically to an emergency drying device for road markings. Background Technology

[0002] Road markings are an indispensable part of road traffic management. By drawing various lines, arrows, words, and vertical markings on the road surface, road markings convey information such as guidance, restrictions, and warnings to traffic participants. Road markings generally include: white dashed lines, white solid lines, yellow dashed lines, and yellow solid lines. These different colored lines are obtained by pumping paint and spraying it through nozzles.

[0003] Existing road marking spraying equipment requires drying the paint after it is sprayed onto the ground. The road surface must also be dry before spraying the paint, as the paint is easier to solidify on a dry road surface. Currently, the equipment for drying road surfaces and paint mainly uses direct hot air blowing. Hot air is blown vertically to the ground through ducts to achieve maximum drying efficiency. However, after the hot air is blown vertically to the ground, it quickly dissipates in all directions, resulting in a large amount of heat waste and low thermal energy utilization. Utility Model Content

[0004] The purpose of this invention is to provide an emergency drying device for road markings to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An emergency drying device for road markings includes a construction vehicle. A controller is installed on the top of the construction vehicle, and a hot air device is installed on the top of the construction vehicle. The hot air device includes a heater and a fan connected to the end of the heater. The air outlet of the fan is connected to a ventilation duct. The extension end of the ventilation duct is perpendicular to the ground, and a recycling hood is connected to the end of the ventilation duct. A fixing frame is fixed on the top of the construction vehicle, and the fixing frame is fixedly connected to the ventilation duct by bolts.

[0007] Preferably, the top of the recycling hood has a through hole, a sealing ring is provided at the edge of the through hole, the extension end of the ventilation duct passes through the through hole, the inner wall of the sealing ring is tightly fitted with the ventilation duct, and the sealing ring and the ventilation duct are fixedly connected by bolts.

[0008] Preferably, the bottom of the construction vehicle is fixed with a frame, the bottom of the frame is provided with a fixing plate, the bottom of the fixing plate is provided with two baffles, the two baffles are arranged in a V shape, and the bottom of the baffles is provided with multiple rubber plates in parallel.

[0009] Preferably, the construction vehicle is further equipped with a base plate on its top, an energy storage device is installed on the top of the base plate, and a solar panel is fixed on the top of the outer casing.

[0010] Preferably, the construction vehicle is provided with an outer box on the top, the surface of the outer box is provided with ventilation holes, an air inlet plate is fixed on the top of the outer box, and an air guide hole is provided on one side of the air inlet plate, the air guide hole communicating with the internal space of the outer box.

[0011] Preferably, a hole is provided on one side surface of the outer casing, the hole corresponds to the position of the controller, and a protective film is provided in the hole.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] By using a recovery hood structure installed at the end of the ventilation duct, the recovery hood is close to the ground. The hot air exhausted from the ventilation duct is blown towards the ground and dispersed in all directions, but is blocked by the recovery hood. After the dispersed hot air enters the interior of the recovery hood, it flows to the road surface on both sides under the guidance of the recovery hood. This is beneficial for drying the road surface on both sides of the drying position, thereby avoiding the moisture on the road surface on both sides from wetting the drying position and improving the drying effect. During the drying process, the recovery of hot air improves the utilization rate of heat energy and ensures that the drying position is not affected by the moisture on the road surface on both sides.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1 - Figure 6 The road marking emergency drying equipment shown includes a construction vehicle 1, a controller 11 installed on the top of the construction vehicle 1, a hot air device installed on the top of the construction vehicle 1, the hot air device includes a heater 13 and a fan 14 connected to the end of the heater 13, the air outlet of the fan 14 is connected to a ventilation duct 7, the extension end of the ventilation duct 7 is perpendicular to the ground, the end of the ventilation duct 7 is connected to a recycling cover 8, and a fixing frame 6 is fixed on the top of the construction vehicle 1, the fixing frame 6 and the ventilation duct 7 are fixedly connected by bolts.

[0025] In this embodiment, during the drying process, the construction vehicle 1 travels on the target road. By adjusting the travel path of the construction vehicle 1, the ventilation duct 7 can be aligned with different positions on the road to adjust the drying position. After the user determines the drying position, the construction vehicle 1 travels at a constant speed and starts the heater 13. The heater 13 is powered on and begins to generate heat. The working principle of the heater 13 is existing technology and will not be described in detail here. During the operation of the fan 14, the heat generated by the heater 13 is extracted. The heat passes through the ventilation duct 7 and is discharged from the bottom of the ventilation duct 7. Then it is blown vertically towards the drying position. After the hot air impacts the ground, the hot air rebounds upwards and disperses. During this process, the recovery hood 8 collects the hot air (the hot air is blocked by the recovery hood 8 and cannot continue to flow along the rebound direction). The hot air accumulated in the recovery hood 8 flows downward along the inner wall of the recovery hood 8 and is then blown towards the road surface on both sides of the drying position.

[0026] like Figure 1 - Figure 4As shown, specifically, the top of the recovery hood 8 has a through hole, and a sealing ring 18 is provided at the edge of the through hole. The extended end of the ventilation duct 7 passes through the through hole, and the inner wall of the sealing ring 18 is tightly fitted with the ventilation duct 7. The sealing ring 18 and the ventilation duct 7 are fixedly connected by bolts. It should be noted that the sealing ring 18 tightly connects the ventilation duct 7 and the top of the recovery hood 8 to ensure that hot air will not overflow between the sealing ring 18 and the ventilation duct 7 after it is discharged from the ventilation duct 7, and also improves the stability between the sealing ring 18 and the ventilation duct 7.

[0027] like Figure 1 - Figure 5 As shown, a frame 15 is fixed to the bottom of the construction vehicle 1. A fixing plate 16 is provided at the bottom of the frame 15. Two baffles 9 are provided at the bottom of the fixing plate 16. The two baffles 9 are arranged in a V-shape. Multiple rubber plates 17 are arranged parallel to each other at the bottom of the baffles 9. The bottom end of the baffles 9 is close to the ground and will not contact the ground. In specific use, when the construction vehicle 1 is moving, the V-shaped baffles 9 can disperse the impurities on the road to both sides to ensure that the impurities on the road will not cover the drying position, avoid the impurities from contaminating the markings already sprayed on the road, and also protect the unmarked road surface, keeping the road surface free of dirt, so that users can use marking equipment to perform marking operations at the drying position later.

[0028] like Figure 1 and Figure 2 As shown, a base plate 101 is fixed to the top of the construction vehicle 1, and an energy storage device 12 is installed on the top of the base plate 101. A solar panel 2 is fixed to the top of the outer casing 4. The solar panel 2 absorbs solar energy to generate electricity on sunny days. The electrical energy is transmitted through cables and stored in the energy storage device 12. The energy storage device 12 stores electrical energy and can provide power to the heater 13, the fan 14 and the controller 11. It should be noted that the solar power generation and energy storage technology is existing technology and will not be described in detail here.

[0029] like Figure 1 and Figure 6 As shown, the construction vehicle 1 has an outer casing 4 on its top. The surface of the outer casing 4 has ventilation holes 5. An air inlet plate 3 is fixed on the top of the outer casing 4. An air guide hole 19 is opened on one side of the air inlet plate 3. The air guide hole 19 communicates with the internal space of the outer casing 4. A hole is opened on one side of the outer casing 4. The hole corresponds to the position of the controller 11. A protective film 10 is installed in the hole. Specifically, during the process of drying the road surface or drying the marking paint, the construction vehicle 1 drives on the road. During the driving process, air enters the outer casing 4 through the air guide hole 19. The flowing air circulates inside the outer casing 4 and is finally discharged from the ventilation hole 5, thereby realizing the air circulation inside the outer casing 4, which is conducive to the heat dissipation and ventilation of the energy storage device 12 inside the outer casing 4.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
