[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Current snow removal methods primarily involve spraying de-icing agents onto roads after snowfall to lower the freezing point of water on the road surface and prevent refreezing, or using cleaning trucks with vacuuming capabilities to clean and remove snow. However, the effectiveness of de-icing agents in lowering the freezing point of water on roads is limited. When the ambient temperature is low enough, even after spraying de-icing agents, the water can still freeze. Therefore, in areas with sufficiently low winter temperatures, spraying de-icing agents to remove snow and prevent road icing is not ideal. While cleaning trucks with vacuuming capabilities can remove most of the snow and water, the removal is not thorough, leaving some snow or water residue on the road surface. This residue eventually forms a thin layer of ice at low temperatures, severely impacting travel convenience and traffic safety.

[0028] To address the aforementioned issues, the main objective of this application is to propose a road cleaning vehicle that, while clearing and removing snow from the road surface, further reduces the residue of snow or water accumulation, prevents road icing in low-temperature environments, and enhances road traffic safety.

[0029] Figure 1 For a schematic diagram of the road cleaning vehicle structure provided in one embodiment of this application, please refer to... Figure 1 The road cleaning vehicle includes: a vehicle chassis 1, a controller 2, a negative pressure fan 3, a heater 4, a hot air blower 5, a housing 6, a heat conduction pipe 7, and a suction pipe 8.

[0030] The aforementioned housing 6 is mounted on the aforementioned vehicle chassis 1. The aforementioned housing 6 has a first cavity 61 and a second cavity 62. The aforementioned controller 2, the aforementioned negative pressure fan 3, the aforementioned heater 4 and the aforementioned hot air fan 5 are all fixedly mounted in the aforementioned first cavity 61. Furthermore, the aforementioned controller 2 is connected to the drive end of the aforementioned negative pressure fan 3, the control end of the aforementioned heater 4 and the drive end of the aforementioned hot air fan 5.

[0031] The air inlet of the negative pressure fan 3 is connected to the second cavity 62, and the air outlet of the negative pressure fan 3 is connected to the outside through the air outlet on the housing 6. One end of the suction pipe 8 is located inside the second cavity 62, and the other end of the suction pipe 8 is set towards the road surface to suck the dirt on the road surface into the second cavity 62.

[0032] The air inlet of the heater 4 is connected to the outside through the air inlet on the housing 6. The heat pipe 7 is disposed in the second cavity 62. The air outlet of the heater 4 is connected to one end of the heat pipe 7 through the hot air blower 5. The other end of the heat pipe 7 faces the road surface to dry the road surface.

[0033] For example, both the negative pressure fan 3 and the hot air fan 5 may include a motor and an impeller, and the motor and impeller can be connected by a drive. When the motor rotates, it can drive the impeller to rotate, thereby realizing the exhaust / intake of air. It can be seen that the speed and direction of rotation of the motor can be fixed or adjustable. However, the specific type, model, performance parameters of the motor, the type, shape, size, and material of the impeller, and the specific drive connection method between the motor and the impeller can all be selected and determined according to the actual situation, and are not limited here. Furthermore, the impeller and motor in the negative pressure fan 3 can be the same as or different from the impeller and fan in the hot air fan 5, and are not limited here.

[0034] The first cavity 61 and the second cavity 62 of the aforementioned housing 6 can be separated, for example, by a partition or the like provided in the housing 6. The first cavity 61 can be used to accommodate, for example, the controller 2, the negative pressure fan 3, the heater 4, and the hot air blower 5. The second cavity 62 can be used to accommodate, for example, snow, dirt, etc. sucked in by the suction pipe 8. Under normal circumstances, the space of the second cavity 62 can be larger than that of the first cavity 61, but this is not a limitation. The size ratio of the first cavity 61 and the second cavity 62 can be adjusted and determined according to actual needs.

[0035] The controller 2 is connected to the drive end of the negative pressure fan 3, the control end of the heater 4, and the drive end of the hot air blower 5. For example, the connection can be achieved through a connection method including but not limited to electrical connection. The controller 2 can control the speed of the motors in the negative pressure fan 3 and the hot air blower 5, or control the heating temperature or heating power of the heater 4. The specific details are not limited here.

[0036] The air inlet of the negative pressure fan 3 is connected to the second cavity 62, and the air outlet of the negative pressure fan 3 is connected to the outside through the air outlet on the housing 6. For example, when the negative pressure fan 3 is started, the motor drives the impeller to rotate, drawing air from the second cavity 62 through the air inlet and discharging it from the air outlet to the outside of the housing 6. This reduces the air in the second cavity 62 and lowers the air pressure. One end of the suction pipe 8 is located inside the second cavity 62, and the other end of the suction pipe 8 is set towards the road surface to suck the dirt on the road surface into the second cavity 62. That is, for example, when the air pressure inside the second cavity 62 decreases, a negative pressure is generated inside. The suction pipe 8, which connects the second cavity 62 and the outside of the housing 6 and is set towards the road surface, can suck snow, dirt, etc. on the road surface into the second cavity 62. Furthermore, the air outlet of the aforementioned negative pressure fan 3 is connected to the outside through the air outlet on the aforementioned housing 6. For example, this could mean that the air outlet of the aforementioned negative pressure fan 3 is directly opposite the air outlet on the housing 6, thereby directly exhausting air to the outside of the housing 6 through the air outlet. Alternatively, the air outlet of the negative pressure fan 3 can be connected to the air outlet on the housing 6 through a connecting pipe, etc., thus achieving communication with the outside. Of course, the specific connection method can be adjusted and determined according to the positional relationship between the air outlet of the negative pressure fan 3 and the air outlet on the housing 6, with the aim of ensuring that the negative pressure fan 3 can smoothly exhaust air to the outside of the housing 6 (i.e., discharge air).

[0037] The air inlet of the heater 4 is connected to the outside through the air inlet on the housing 6. This is similar to the principle that the air outlet of the negative pressure fan 3 is connected to the outside through the air outlet on the housing 6. In other words, the air inlet of the heater 4 is connected to the outside through the air inlet on the housing 6. For example, the air inlet of the heater 4 may be directly opposite the air inlet on the housing 6, or the air inlet of the heater 4 may be connected to the air inlet on the housing 6 through a connecting pipe, thereby achieving communication with the outside. When the hot air blower 5 is started, the air outside the housing 6 is drawn in through the air inlet on the housing 6 and the air inlet of the heater 4. After being heated by the heater 4, the air is discharged from the air outlet of the heater 4 through the hot air blower 5 and the heat pipe 7 to the road surface facing the heat pipe 7. The heated air (i.e., hot air) quickly melts the snow and evaporates the water on the road surface, thereby drying the road surface.

[0038] The heat pipe 7 is disposed within the second cavity 62. For example, this could mean that the main part of the heat pipe 7 is disposed within the second cavity 62. However, one end of the heat pipe 7 can actually pass through the partition or similar material from the second cavity 62 and connect to the hot air blower 5 in the first cavity 61. Alternatively, the hot air blower 5 and one end of the heat pipe 7 can directly abut against both sides of the partition, and be connected via a sealing connection port or similar material provided on the partition. In this way, one end of the heat pipe 7 does not need to enter the first cavity 61. The other end of the heat pipe 7 can, for example, pass through the housing 6 and extend outside the housing 6 to be close to and facing the road surface. During the process of hot air in the heater 4 being discharged to the road surface facing the direction of the heat pipe 7 via the hot air blower 5 and the heat pipe 7, since the main part of the heat pipe 7 is located in the second cavity 62, the hot air can exchange heat with the snow, water and other substances contained in the second cavity 62, thereby preventing the snow, water and other substances in the second cavity 62 from freezing and being difficult to pour out.

[0039] It is understood that the specific arrangement of the heat pipe 7 and the connection between the heat pipe 7 and the hot air blower 5 are only possible examples. The actual specific arrangement of the heat pipe 7 and the connection between the heat pipe 7 and the hot air blower 5 may be different from the above examples. It is possible to discharge the hot air in the heater 4 through the hot air blower 5 and the heat pipe 7 to the road surface in the direction of the heat pipe 7.

[0040] The road cleaning vehicle provided in this application includes: a vehicle chassis 1, a controller 2, a negative pressure fan 3, a heater 4, a hot air blower 5, a housing 6, a heat-conducting pipe 7, and a suction pipe 8. The housing 6 is mounted on the vehicle chassis 1 and has a first cavity 61 and a second cavity 62. The controller 2, the negative pressure fan 3, the heater 4, and the hot air blower 5 are all fixedly mounted within the first cavity 61. The controller 2 is connected to the drive end of the negative pressure fan 3, the control end of the heater 4, and the drive end of the hot air blower 5. The air inlet of the negative pressure fan 3 communicates with the second cavity 62, and the air outlet of the negative pressure fan 3 communicates with the outside through an air outlet on the housing 6. One end of the suction pipe 8 is located within the second cavity 62, and the other end of the suction pipe 8 faces the road surface to suck dirt from the road surface into the second cavity 62. The air inlet of the heater 4 is connected to the outside through the air inlet on the housing 6. The heat-conducting pipe 7 is disposed in the second cavity 62. The air outlet of the heater 4 is connected to one end of the heat-conducting pipe 7 through the hot air blower 5. The other end of the heat-conducting pipe 7 faces the road surface to dry the road surface. The road cleaning vehicle is equipped with a negative pressure fan 3, a heater 4, and a hot air blower 5, as well as corresponding supporting components. The negative pressure fan 3, heater 4, and hot air blower 5 can be controlled by the controller 2. This allows the road cleaning vehicle to clean and remove snow and dirt from the road surface while simultaneously blowing out hot air to dry the road surface, further reducing the residue of snow or water on the road surface, thereby preventing the road surface from freezing in low-temperature environments and enhancing road traffic safety.

[0041] Figure 2 This is a schematic diagram of a road cleaning vehicle structure provided in another embodiment of this application. Optionally, please refer to... Figure 1 and Figure 2 Based on the above embodiments, the road cleaning vehicle may further include: a suction nozzle 9.

[0042] The suction nozzle 9 is located at the front of the axle below the vehicle chassis 1. The suction nozzle 9 is connected to the vehicle chassis 1 via connecting brackets 10 on both sides of the vehicle chassis 1. The other end of the suction pipe 8 is connected to the suction nozzle 9.

[0043] For example, the suction nozzle 9 can be used to increase the suction area of ​​the road surface. It is understood that the side of the suction nozzle 9 facing the road surface can be provided with a suction trough, suction port, etc., while the side of the suction nozzle 9 facing away from the road surface can be provided with a connection port for connecting to the other end of the suction pipe 8. This connection port can communicate with the aforementioned suction trough, suction port, etc., to suck in snow, dirt, etc., through the suction trough, suction port, etc., into the suction pipe 8, and then discharge it into the second cavity 62 in the aforementioned housing 6. Of course, the above is only one possible example; the actual shape, size, and layout of the suction nozzle 9 can be adjusted as needed, and are not limited here.

[0044] In addition, one or two rollers can be provided at each end of the nozzle 9. These rollers can bring the nozzle 9 close to the road surface and enhance the suction effect, while preventing the nozzle 9 from directly contacting the road surface and being damaged by friction.

[0045] Furthermore, based on the above embodiment, there are two suction pipes 8, one end of each suction pipe 8 is located on both sides of the second cavity 62, and the other end of each suction pipe 8 is connected to the suction nozzle 9. For example, please refer to... Figure 2 This embodiment is designed to accelerate the discharge of sucked-in snow, dirt, etc., into the second cavity 62 of the aforementioned housing 6, and to make the accumulation of snow, dirt, etc., in the second cavity 62 of the aforementioned housing 6 more uniform, making full use of the space of the second cavity 62, and preventing the center of gravity of the road cleaning vehicle from shifting, thereby compromising driving stability. It is understood that, in order to achieve the above effects, the aforementioned suction pipes 8 can also be three, four, etc., as long as they are reasonably distributed and arranged, and the specific number of suction pipes 8 is not specifically limited here.

[0046] Additionally, please refer to Figure 1 Based on the aforementioned embodiments, the connecting bracket 10 can be, for example, a retractable connecting bracket 10. The retractable connecting bracket 10 is used to move the suction nozzle 9 closer to or away from the road surface. This embodiment is designed such that when the road cleaning vehicle is working, the suction nozzle 9 can be lowered via the retractable connecting bracket 10 to bring it closer to the road surface, thereby improving the suction effect. When the road cleaning vehicle stops working and is driving normally, the suction nozzle 9 can be retracted via the retractable connecting bracket 10 to move it away from the road surface, preventing the suction nozzle 9 from colliding with obstacles on the road and enhancing vehicle passability. The retractable connecting bracket 10 can be manually retractable or electrically retractable. If electrically retractable, it can be equipped with an electric motor or other electric drive device, which can also be connected to the controller 2, but is not limited thereto.

[0047] Alternatively, please refer to Figure 2Based on the aforementioned embodiments, the road cleaning vehicle may further include a drying nozzle 11.

[0048] The aforementioned drying nozzle 11 is located at the rear of the axle below the vehicle chassis 1, and the aforementioned drying nozzle 11 is connected to the other end of the aforementioned heat pipe 7.

[0049] For example, the aforementioned drying nozzle 11 can be used to increase the blowing area on the road surface to improve the road surface drying efficiency. It is understood that the side of the drying nozzle 11 facing the road surface can be provided with an air outlet, an air duct, etc., while the side of the drying nozzle 11 facing away from the road surface can be provided with a connection port for connecting to the other end of the heat-conducting pipe 7. This connection port can communicate with the aforementioned air outlet, air duct, etc., to discharge hot air from the heat-conducting pipe 7 to the road surface through the air outlet, air duct, etc., thereby promoting the melting of snow and the rapid evaporation of water on the road surface. Of course, the above is only a possible example; the actual shape, size, and layout of the drying nozzle 11 can be adjusted as needed and are not limited here.

[0050] Furthermore, based on the above embodiments, the vehicle chassis 1 is also provided with an angle adjustment mechanism, which is connected to the drying nozzle 11 to adjust the angle of the drying nozzle 11 relative to the road surface. In scenarios such as snow removal on one side of the road, the angle of the drying nozzle 11 relative to the road surface can be adjusted to discharge hot air more specifically, thereby completing snow removal more accurately and efficiently.

[0051] Furthermore, based on the above embodiments, the angle adjustment mechanism can be a manually adjustable connecting rod or an electrically adjustable rod. For example, if the angle adjustment mechanism is an electrically adjustable rod, it can be equipped with an electric drive device such as a motor. This electric drive device can also be connected to the controller 2, but is not limited thereto.

[0052] Optionally, based on the foregoing embodiments, a capacity monitoring sensor may be installed inside the housing 6, and the capacity monitoring sensor is connected to the controller 2. For example, when the capacity monitoring sensor detects that the amount of road debris contained in the second cavity 62 has reached a preset capacity threshold, the controller 2 may issue a prompt, not limited to sound or light, so that the driver can promptly shut down the negative pressure fan 3 to stop the suction of snow, debris, etc. from the road surface. Alternatively, when the capacity monitoring sensor detects that the amount of road debris contained in the second cavity 62 has reached the preset capacity threshold, the controller 2 may also directly control the negative pressure fan 3 to shut down to prevent the suction of snow, debris, etc. from overflowing due to the driver's delayed operation. Of course, how the controller 2 specifically shuts down the negative pressure fan 3 when the capacity monitoring sensor detects that the amount of road debris contained in the second cavity 62 has reached the preset capacity threshold can be determined according to the actual situation and is not limited to the examples described above.

[0053] Furthermore, based on the aforementioned embodiments, the bottom of the aforementioned container 6 may be provided with a tilting mechanism connected to the aforementioned vehicle chassis 1 to drive the container 6 to tilt and unload materials. This tilting mechanism may be, for example, an electric tilting mechanism such as an electro-hydraulic rod, but is not limited thereto. It is understood that the drive device of this electric tilting mechanism may also be connected to the aforementioned controller 2. Tilting and unloading the container 6 may, for example, refer to the discharge of road debris or other contaminants contained in the second cavity 62 of the container 6 through tilting. For example, the container 6 may be provided with an openable rear cover or top cover to facilitate the tilting and discharge, but specific details are not limited here.

[0054] Optionally, based on any of the above embodiments, the vehicle chassis 1 can be, for example, an electric vehicle chassis 1 equipped with a power source, and the controller 2, negative pressure fan 3, heater 4, hot air fan 5, etc. can all be powered by the power source, but are not limited thereto.

[0055] It is understood that the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
