[0021] The following is based on the attached Figure 1-3 The present invention will be further described:

[0022] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Therefore, they cannot be understood as limiting the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides a ground cleaning device under a road barrier on the basis of the existing technology, including: a driving unit 10 and a cleaning unit 30, the fixing seat of the driving unit 10 is arranged in front of the vehicle, the driving unit 10 is provided with a swing rod 20, the cleaning unit 30 includes an avoidance component and a flushing component, the avoidance component is connected to the swing rod 20, and the flushing component is connected to the bottom of the avoidance component.

[0026] In the application of this embodiment, the fixing seat of the driving unit 10 can be directly set in front of the vehicle. This design allows the device to be easily combined with the vehicle without the need for large-scale modification of the vehicle, lowering the threshold for use and facilitating promotion and application. The driving unit 10 is provided with a swing rod 20, and the swing rod 20 is connected to the avoidance component of the cleaning unit 30. The setting of the swing rod can drive the cleaning unit to swing to a certain extent, which can better meet the cleaning needs of the ground under the isolation fence, expand the cleaning range, and reduce cleaning dead corners. The cleaning unit 30 includes an avoidance component, which lays a structural foundation for the subsequent automatic avoidance when encountering obstacles such as the guardrail base and columns, and can avoid collision damage between the device and the obstacles, ensuring the continuity and stability of the cleaning operation. The avoidance component is connected to the swing rod 20, and the flushing component is connected to the bottom of the avoidance component. The connection method between the components enables power to be effectively transmitted, ensuring that the power of the driving unit can be transmitted to the cleaning unit through the swing rod, allowing the flushing component to smoothly carry out cleaning operations, thereby improving overall work efficiency.

[0027] The above-mentioned driving part 10 includes: a fixed frame, a swing frame, a swing frame swing mechanism, a working mechanism bracket, a working mechanism bracket lifting mechanism and a swing rod swing mechanism. The swing rod swing mechanism is connected to the swing rod 20. The fixed frame, the swing frame, the swing frame swing mechanism, the working mechanism bracket, the working mechanism bracket lifting mechanism and the swing rod swing mechanism are described in detail in the Chinese invention patent application number 201810932379.8, named Ground Cleaning Device under Road Guardrail, and will not be repeated in this patent.

[0028] Furthermore, the ground cleaning device under the road barrier also includes a protective portion 40 connected to the swing arm 20 and disposed between the cleaning portion 30 and the driving portion 10. The protective portion 40 is connected to the swing arm 20 and disposed between the cleaning portion 30 and the driving portion 10. During the cleaning operation, the protective portion 40 prevents mud, water, and debris generated during cleaning from splashing onto the driving portion 10, preventing these contaminants from corroding or clogging the mechanical structure and components of the driving portion, thereby extending the service life of the driving portion and reducing the occurrence of malfunctions. The presence of the protective portion provides a certain degree of protection for the cleaning portion 30, reducing the direct impact of external factors on the cleaning portion. This is particularly important when the cleaning portion is performing evasive maneuvers or operating in complex road conditions, enhancing the stability of the cleaning portion's operation and ensuring the proper completion of operations such as flushing and evasion. The protective portion, located between the cleaning portion and the driving portion, forms a physical barrier that relatively isolates the working areas of the various components of the device, reducing the risk of interference between the cleaning portion and the driving portion due to accidental contact during movement, and improving the safety and reliability of the entire device.

[0029] In this embodiment, the ground cleaning device under the road barrier further includes an obstacle sensor 50. The fixed end of the obstacle sensor 50 is connected to the swing arm 20. The obstacle sensor 50 and the driving unit 10 are separated by a protective portion 40. The obstacle sensor 50 and the cleaning unit 30 are separated. The protective portion 40 is connected to the swing arm 20 and arranged between the cleaning unit 30 and the driving unit 10. During the cleaning operation, it can prevent mud, water, and debris generated during cleaning from splashing onto the driving unit 10, preventing these contaminants from corroding or clogging the mechanical structure and components of the driving unit, thereby extending the service life of the driving unit and reducing the occurrence of malfunctions. The presence of the protective portion can provide protection for the cleaning unit 30 to a certain extent, reducing the direct impact of external factors on the cleaning unit. In particular, when the cleaning unit is performing avoidance maneuvers or operating in complex road conditions, it can enhance the stability of the cleaning unit's operation and ensure that it can normally complete operations such as flushing and avoidance. The protective part is located between the cleaning part and the driving part, forming a physical barrier that relatively isolates the working areas between the various components of the device, reduces the risk of interference between the cleaning part and the driving part due to accidental contact during movement, and improves the safety and reliability of the entire device operation.

[0030] In an exemplary embodiment, the avoidance component includes: an avoidance fixed seat 301, an L-shaped fixed plate 302, an avoidance connecting shaft 303 and an avoidance wheel 304, the avoidance fixed seat 301 is connected to the swing rod 20, the vertical side of the L-shaped fixed plate 302 is connected to the avoidance fixed seat 301, the avoidance connecting shaft 303 is connected to the horizontal side of the L-shaped fixed plate 302, the flushing component is connected to the avoidance connecting shaft 303, and the avoidance wheel 304 is movably connected to the avoidance connecting shaft 303.

[0031] In the present embodiment, the avoidance wheel 304 in the avoidance assembly is movably connected to the avoidance connecting shaft 303. When the device encounters obstacles such as the guardrail base and columns, the movably connected avoidance wheel can trigger the avoidance action more sensitively. In combination with the structural design of the L-shaped fixing plate 302 and the avoidance connecting shaft 303, the entire avoidance assembly can flexibly rotate and deflect under the action of obstacles, ensuring that the device can smoothly avoid obstacles and greatly improving its adaptability to complex road conditions. The avoidance fixing seat 301 is connected to the swing rod 20, and the vertical side of the L-shaped fixing plate 302 is connected to the avoidance fixing seat 301. This multi-level fixed connection method allows the avoidance assembly and the swing rod of the driving part to form a stable overall structure, which can effectively transmit the power of the swing rod, ensure that the flushing assembly maintains a stable position and posture during operation, and reduce operational deviations caused by loose connections. The flushing assembly is connected to the avoidance connecting shaft 303, so that the flushing assembly can adjust its position synchronously with the action of the avoidance assembly. Once the avoidance assembly has avoided an obstacle and reset, the flushing assembly quickly returns to its operating position, ensuring the continuity of operations like flushing and blowing away snow and mud, and preventing interruptions to the avoidance action that could affect cleaning efficiency. The horizontal edge of the L-shaped fixing plate 302 is connected to the avoidance connecting shaft 303, and the vertical edge is connected to the avoidance fixing seat 301. This L-shaped structure effectively connects all components while making rational use of space, making the overall avoidance assembly more compact and easier to install within the limited space in front of the vehicle without interfering with other parts of the device.

[0032] Furthermore, the flushing component includes: a connecting block 306 and a spray pipe 305, the connecting block 306 is connected to the bottom of the avoidance component, the fluid inlet of the spray pipe 305 is connected to the external water tank and / or the external air pump pipeline, the spray pipe 305 is connected to the connecting block 306, and the spray pipe 305 is provided with a spray port on the side pointing to the ground, and the spray port includes an air nozzle and / or a water nozzle.

[0033] The flushing assembly's connecting block 306 connects to the bottom of the avoidance assembly. This connection ensures the flushing assembly can stably follow the avoidance assembly's movements, maintaining coordination with the avoidance assembly during both obstacle avoidance and reset operations, preventing operational deviations due to unstable connections. Furthermore, the spray pipe 305 is connected to the connecting block 306, further enhancing the overall structural stability of the flushing assembly. The fluid inlet of the spray pipe 305 can be connected to an external water tank and / or an external air pump line. The spray outlet includes an air nozzle and / or a water nozzle, allowing the device to flexibly switch between water and air spray modes depending on the situation. In summer, the water nozzle can be used to flush the ground below the guardrail to deal with mud and water. In winter, or when dry debris needs to be handled, the air nozzle can be used to blow away snow, mud, or dust, significantly improving the device's cleaning adaptability to different seasons and different pollutants. The spray nozzle on the ground-facing side of the spray pipe 305 can precisely focus the spray on the ground area below the guardrail, ensuring that the sprayed water or air directly impacts the area being cleaned, improving cleaning efficiency. This directional design also reduces water and air waste, allowing energy and resources to be more concentrated on cleaning operations. The connections between the various components are simple and clear. If the spray pipe 305, air nozzle, or water nozzle becomes worn or clogged, they can be easily disassembled and replaced individually, eliminating the need for extensive overhaul of the entire flushing assembly. This reduces maintenance costs and difficulty, and extends the overall life of the device.

[0034] like Figure 3 As shown, the obstacle sensing unit 50 includes: a first connecting rod 501, a telescopic assembly 507, a positioning seat 506, a movable rod 503, a return spring 505 and a sensing probe 502, the first connecting rod 501 is connected to the swing rod 20, the fixed end of the telescopic assembly 507 is connected to the first connecting rod 501, the positioning seat 506 is connected to the execution end of the telescopic assembly 507, the movable rod 503 is movably connected to the positioning seat 506, the movable rod 503 and the telescopic assembly 507 are spaced apart, the first end of the return spring 505 is connected to the positioning seat 506, the second end of the return spring 505 is connected to the first end of the movable rod 503, the return spring 505 is spaced apart from the telescopic assembly 507, the return spring 505 is used to move the movable rod 503 from the working position to the initial position, the sensing probe 502 is connected to the second end of the movable rod 503, and the sensing probe 502 and the return spring 505 are spaced apart.

[0035] In this embodiment, the sensing probe 502 is connected to the movable rod 503. As a component that directly contacts obstacles, it can trigger the induction first when the device approaches obstacles such as guardrail bases and columns. Compared with relying solely on passive contact avoidance of the avoidance component, this active detection mechanism can transmit obstacle signals in advance, reserve reaction time for the action of the avoidance component, greatly improve the timeliness of avoidance, and reduce the risk of collision. The fixed end of the telescopic component 507 is connected to the first connecting rod 501, and the execution end is connected to the positioning seat 506. The overall height and position of the sensing part can be adjusted by telescoping to adapt to obstacles such as guardrail bases and columns of different specifications; the movable rod 503 is movably connected to the positioning seat 506, and can flexibly rotate according to the angle at which the sensing probe contacts the obstacle, further improving the adaptability to various obstacles.

[0036] The two ends of the reset spring 505 are respectively connected to the positioning seat 506 and the movable rod 503. When the sensing probe bypasses the obstacle, the reset spring can drive the movable rod 503 to quickly return from the working position to the initial position, so that the sensing probe immediately resumes the detection state. This automatic reset function ensures that the device does not interrupt detection during continuous operation, and cooperates with the reset action of the avoidance component to form a "detection-avoidance-reset-redetection" cycle to ensure the continuity of the cleaning operation. The first connecting rod 501 is connected to the swing rod 20, so that the obstacle sensing part and the avoidance component share the same power transmission basis, ensuring that the movement rhythm of the two is synchronized; the sensing signal triggered by the sensing probe can directly link the avoidance component action (such as the rotation of the avoidance wheel 304, the offset of the avoidance connecting shaft 303), forming a "detection-response" coordination mechanism, making the avoidance action of the avoidance component more accurate, and avoiding collisions or excessive avoidance caused by the lack of synchronization between sensing and avoidance. The movable rod 503 and the telescopic component 507, the return spring 505 and the telescopic component 507, and the sensing probe 502 and the return spring 505 are all arranged at intervals. This structural design avoids mutual friction or jamming of the components during movement, ensures smooth movements such as telescopic, rotation, and reset, and improves the overall stability and service life of the sensing part.

[0037] Furthermore, the obstacle sensing unit 50 also includes a buffer block 504, the first end of which is connected to the positioning seat 506, and the second end of which is connected to the movable rod 503. The buffer block 504 is connected to the positioning seat 506 and the movable rod 503 at both ends. When the sensing probe 502 contacts an obstacle and drives the movable rod 503 to rotate, the buffer block can absorb and buffer the impact force between the two, preventing the movable rod and the positioning seat from being damaged due to direct hard collision, thereby extending the service life of the component. When the reset spring 505 drives the movable rod 503 to reset, the buffer block can act as a buffer, reducing the impact of the movable rod on the positioning seat when resetting, making the entire reset action smoother and reducing the impact of vibration caused by the impact on the connection stability of other components of the sensing unit. The buffer block itself has a certain degree of elasticity and deformation capacity, which can provide moderate resistance when the movable rod rotates, helping to control its rotation range, preventing the movable rod from excessively rotating due to excessive impact force from the obstacle, ensuring that the obstacle signal transmitted by the sensing probe is more accurate, and providing a more reliable basis for the coordinated action of the avoidance component.

[0038] The second embodiment of the present invention provides a road sweeper based on the first embodiment, comprising a vehicle and the above-mentioned road barrier ground cleaning device. The road sweeper combines the vehicle with the road barrier ground cleaning device, enabling the cleaning device to operate synchronously with the vehicle's driving power, eliminating the need for an additional independent mobile carrier for the device, thereby reducing equipment scheduling costs and time. While the vehicle is in motion, the cleaning device can clean the ground below the barrier in real time, achieving the integration of movement and cleaning, significantly improving overall operational efficiency.

[0039] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and exemplary embodiments. They can be applied to a variety of fields suitable for the present invention. Further modifications will be readily apparent to those skilled in the art.
