Description

Technical Field

[0001] This application relates to the field of sanitation and cleaning equipment technology, specifically a convenient cleaning device for smart sanitation. Background Technology

[0002] Against the backdrop of continuous urbanization, sanitation and cleaning operations, as a core link in maintaining urban environmental cleanliness and ensuring public health and safety, directly impact the living experience of urban residents and the overall image of the city through their efficiency and quality. With the introduction and implementation of the concept of "smart sanitation," traditional cleaning methods relying on manual or semi-mechanized processes are gradually transforming towards automation and intelligence. Various cleaning equipment have emerged as key tools for reducing the intensity of sanitation work and increasing operational coverage.

[0003] Currently, roads in old urban areas and older communities generally have problems such as small potholes, protruding manhole covers, and uneven curb stones. The sweeping brushes of sweepers may miss potholes or cause collisions and wear on protrusions. Existing sweeping equipment with height adjustment functions mostly rely on manual operation of adjustment buttons after observing the road conditions to adjust the height of the sweeping brushes. However, in actual operation, uneven areas on the roads in old urban areas are often continuously distributed without obvious patterns. It is difficult for operators to judge the height changes of each uneven area in real time, and the adjustment action often lags behind the speed of the equipment, which may not effectively avoid missed areas or collisions. At the same time, manual adjustment requires frequent interruptions of the equipment's constant speed movement, which reduces the efficiency of operation.

[0004] Therefore, it is necessary to provide a convenient cleaning device for smart sanitation to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figure 1-4 As shown, this application provides a convenient cleaning device for smart sanitation, including a sweeper body 1 as a mobile operating carrier. A cleaning component 2 for sweeping dust and debris from the ground is provided at the front of the sweeper body to ensure effective road cleaning. The cleaning component 2 includes a support frame 21 fixedly installed on the upper part of the sweeper body 1. The support frame 21 provides stable support for subsequent adjustment parts and mounting frames 22, preventing component shaking during operation from affecting cleaning accuracy. A mounting frame 22 is provided at the upper end of the support frame 21. Connecting rods 25 are rotatably installed on both sides of the mounting frame 22. The connecting rods 25 can rotate flexibly around the rotation point of the mounting frame 22, providing a basis for adjusting the angle of the sweeping brush 27.

[0031] Mounting plates 26 are rotatably mounted on one side of the connecting rod 25. A drive motor 28 is fixedly mounted on the upper end of the mounting plate 26. The drive motor 28 serves as the cleaning power source. Its output end passes through the mounting plate 26 and is fixedly mounted with a cleaning brush 27. After the drive motor 28 is started, the motor drives the cleaning brush 27 to rotate at high speed. Through the friction between the brush bristles and the ground, dust, fallen leaves, and small debris on the ground are swept up, and the cleaning operation is completed in conjunction with the collection system of the sweeper.

[0032] The mounting frame 22 has two rotatably mounted second push rods 29 on both sides. The output end of the second push rod 29 is rotatably connected to the rear end of the connecting rod 25, and is specifically used to adjust the angle of the connecting rod 25. When the sweeper needs to clean special areas such as roadside corners and sloping road surfaces, the control system controls the second push rod 29 to extend or retract. The push or pull force generated by the output end of the push rod drives the connecting rod 25 to rotate around the mounting frame 22, adjusting the angle of the sweeping brush 27. When the equipment stops working and needs to be moved to a non-sweeping area, the second push rod 29 can be controlled to extend fully, driving the sweeping brush 27 to retract, avoiding friction between the sweeping brush 27 and the ground that would cause brush bristle wear, and also preventing the sweeping brush 27 from snagging on obstacles and affecting the movement of the equipment.

[0033] like Figure 3-4 As shown, the support frame 21 is also provided with an adjustment part for raising and lowering the mounting frame 22. The adjustment part includes a first push rod 23 fixedly installed on both sides of the support frame 21. The output end of the first push rod 23 is fixedly connected to the mounting frame 22. Multiple guide rods 24 are fixedly installed on the support frame 21. The guide rods 24 are slidably connected to the mounting frame 22. The guide rods 24 can limit the movement direction of the mounting frame 22 to prevent the mounting frame 22 from shifting left or right or tilting when it is raised or lowered, thus ensuring smooth movement.

[0034] When the sweeper faces different ground conditions, the first push rod 23 extends and retracts to drive the mounting bracket 22 to move up and down along the guide rod 24, thereby adjusting the height of the entire cleaning assembly 2. For example, when there are bumps on the ground (such as piles of small stones), the first push rod 23 extends to push the mounting bracket 22 upward, driving the sweeping brush 27 to rise, avoiding damage caused by the bump hitting the sweeping brush 27; when there are depressions on the ground, the first push rod 23 retracts to pull the mounting bracket 22 downward, so that the sweeping brush 27 is close to the bottom of the depression, ensuring that the dust in the depression is thoroughly cleaned.

[0035] Meanwhile, the height can be adjusted according to the thickness of the dust on the ground. When the dust is thick, the height of the sweeping brush 27 can be appropriately reduced to increase the contact pressure between the bristles and the ground and enhance the sweeping power. When the dust is thin, the sweeping brush 27 can be appropriately raised to reduce the wear of the bristles and achieve adjustment as needed.

[0036] like Figure 4-6 As shown, the front end of the sweeper body 1 is equipped with a detection component 3 for detecting the flatness of the ground. The detection component 3 includes a positioning frame 31 fixedly installed on both sides of the front end of the sweeper body 1. The positioning frame 31 provides a stable mounting base for components such as the drive unit and the mounting frame 32, ensuring that the components do not shake during the detection process. The front end of the positioning frame 31 is equipped with a mounting frame 32, and the lower end of the mounting frame 32 is equipped with a mounting seat 33. The lower end of the mounting seat 33 is rotatably equipped with a moving wheel 34. The moving wheel 34 can roll along the ground as the sweeper moves. When there are small potholes, raised manhole covers, uneven curb stones, etc. on the ground, the moving wheel 34 will move up and down with the undulations of the ground, thereby driving the mounting seat 33 to move synchronously.

[0037] A linear displacement sensor 35 is fixedly installed at the upper end of the mounting frame 32. The detection end of the linear displacement sensor 35 passes through the mounting frame 32 and is fixedly connected to the mounting base 33. It can capture the vertical displacement of the mounting base 33 in real time, convert the displacement signal into an electrical signal and transmit it to the control system of the sweeper. The control system analyzes the displacement data to accurately determine the flatness of the ground.

[0038] A spring 36 is fixedly installed between the lower surface of the mounting frame 32 and the upper surface of the mounting base 33. The spring 36 has an elastic return function, which can ensure that the moving wheel 34 is always in close contact with the ground. When the moving wheel 34 encounters a ground protrusion, the pressure of the protrusion on the moving wheel 34 causes the mounting base 33 to move upward, and the spring 36 is compressed. When the moving wheel 34 rolls over the protruding area, the spring 36 returns to its original shape, pushing the mounting base 33 to move downward, so that the moving wheel 34 re-fits the ground. When the moving wheel 34 encounters a depression, the spring 36 extends and pushes the mounting base 33 to move downward, causing the moving wheel 34 to extend into the depression, ensuring that no detection is missed.

[0039] like Figure 5-6 As shown, a guide portion is also provided between the mounting frame 32 and the mounting base 33. The guide portion includes a first positioning rod 37 fixedly installed on both sides of the mounting base 33 and guide blocks 39 on both sides of the upper end of the mounting base 33. The upper end of the first positioning rod 37 is slidably connected to the mounting frame 32. Guide grooves 38 are provided on both sides of the mounting frame 32. The guide blocks 39 are slidably installed in the guide grooves 38. The guide portion can restrict the movement trajectory of the mounting base 33, ensuring that the mounting base 33 only moves up and down in the vertical direction, without left or right offset or rotation, thereby ensuring that the detection data of the linear displacement sensor 35 is accurate and reliable, and avoiding detection errors caused by the offset of the mounting base 33.

[0040] The positioning frame 31 is equipped with a drive unit for driving the moving wheel 34 to move up and down. The working state of the detection component 3 can be flexibly switched according to the operation requirements. The drive unit includes a third push rod 311 fixedly installed on the upper end of the positioning frame 31. A positioning plate 310 is fixedly installed at the rear end of the mounting frame 32. The upper end of the third push rod 311 is fixedly connected to the positioning plate 310. A plurality of second positioning rods 312 are fixedly installed on the upper end of the positioning frame 31. The second positioning rods 312 are slidably connected to the positioning plate 310. The second positioning rods 312 can prevent the positioning plate 310 from tilting when it moves.

[0041] When the sweeper starts its sweeping operation, the control system controls the third push rod 311 to retract, pushing the positioning plate 310 downward along the second positioning rod 312, causing the mounting frame 32, mounting base 33, and moving wheel 34 to move downward simultaneously, making the moving wheel 34 in close contact with the ground and activating the detection function. When the sweeper is traveling at a constant speed on a completely flat road surface and does not require frequent detection, or when it is necessary to replace the moving wheel 34 or maintain the detection component 3, the control system extends the third push rod 311, pulling the positioning plate 310 upward, causing the moving wheel 34 to lift off the ground, avoiding unnecessary wear on the moving wheel 34, and reducing the sweeper's driving resistance.

[0042] When the detection component 3 detects small potholes, manhole cover protrusions, or uneven curb stones on the ground, the linear displacement sensor 35 transmits the detection data to the control system in real time. After rapid analysis, the control system automatically sends a command to the first push rod 23 of the adjustment unit. If a small pothole is detected, the first push rod 23 is retracted, pulling the mounting frame 22 downward, causing the sweeping brush 27 to descend to the bottom of the pothole, preventing the pothole from being suspended and missed. If a manhole cover protrusion or uneven curb stone is detected, the first push rod 23 is extended, pushing the mounting frame 22 upward, causing the sweeping brush 27 to rise and avoid the protruding parts, preventing the sweeping brush 27 from colliding with the protrusion and causing wear or equipment failure. No manual intervention is required, improving the efficiency and safety of sanitation operations.

[0043] like Figure 4 As shown, a first protective cover 313 is fixedly installed on the upper end of the mounting frame 32, which completely covers the linear displacement sensor 35. During cleaning operations, dust raised from the ground, splashed sewage, roadside branches and weeds can easily damage the precision linear displacement sensor 35. A second protective cover 314 is fixedly installed on the lower end of the positioning plate 310, which completely encloses the third push rod 311. If dust or debris enters the telescopic structure of the third push rod 311, problems such as jamming and sealing failure may occur. The second protective cover 314 can isolate external dust, rainwater, and mud, prevent the push rod from being obstructed during telescopic movement, extend the service life of the drive unit, and ensure the normal operation of the lifting function of the detection component 3.

[0044] Working principle: After starting the sweeper body 1, the drive motor 28 on the mounting plate 26 is started first. The motor output drives the sweeping brush 27 to rotate at high speed. Through the friction between the brush bristles and the ground, dust, fallen leaves and small debris are swept up. The swept debris is then collected by the sweeper's collection system, completing the basic cleaning action.

[0045] At this time, based on the initial cleaning area (such as a flat road surface), the cleaning component 2 is preset to a certain state by the control system. The second push rod 29 is kept moderately retracted, so that the connecting rod 25 drives the cleaning brush 27 to maintain a horizontal angle, ensuring that the bristles are evenly attached to the ground. The first push rod 23 is in the middle position, so that the mounting bracket 22 drives the cleaning brush 27 to maintain a reasonable height, which ensures the cleaning force and avoids excessive wear of the bristles.

[0046] The control system retracts the third push rod 311 on the positioning frame 31, pushing the positioning plate 310 downward along the second positioning rod 312. The positioning plate 310 drives the mounting frame 32, mounting base 33, and moving wheel 34 to move downward synchronously until the moving wheel 34 makes close contact with the ground. The moving wheel 34 rolls along the ground as the sweeper moves, preparing for subsequent ground flatness testing. At the same time, the first protective cover 313 and the second protective cover 314 respectively cover the linear displacement sensor 35 and the third push rod 311, isolating external impurities and ensuring that the core components are in good initial condition.

[0047] During the sweeper's operation, the moving wheel 34 moves up and down with the undulations of the ground, causing the mounting base 33 to move synchronously: when there are small potholes on the ground, the spring 36 extends and pushes the mounting base 33 down, so that the moving wheel 34 extends into the pothole; when encountering manhole covers protruding or uneven curb stones, the protrusions squeeze the moving wheel 34, causing the mounting base 33 to move up, and the spring 36 is compressed.

[0048] When the mounting base 33 moves, the first positioning rods 37 on both sides slide along the mounting frame 32, and the guide blocks 39 slide synchronously in the guide grooves 38, ensuring that the mounting base 33 moves only in the vertical direction and avoiding deviation that could affect the detection accuracy. The linear displacement sensor 35 connected to the mounting base 33 captures the displacement in real time, converts the displacement signal into an electrical signal and transmits it to the control system. The system then uses data analysis to accurately determine the type of ground unevenness.

[0049] If a small pit is detected, the first push rod 23 is retracted, and the mounting frame 22 is pulled down along the guide rod 24. The mounting frame 22 drives the connecting rod 25, the mounting plate 26 and the cleaning brush 27 to descend synchronously, so that the cleaning brush 27 extends to the bottom of the pit, avoiding the pit from being suspended and missed, and ensuring that there are no dead corners in the cleaning.

[0050] If a protruding manhole cover or uneven curb is detected, the first push rod 23 is extended, pushing the mounting frame 22 upward along the guide rod 24, which in turn lifts the sweeping brush 27 to avoid the protruding parts and prevent the sweeping brush 27 from colliding with the protrusion, causing brush bristle wear or equipment failure.

[0051] If a thick layer of dust is detected on the ground, the first push rod 23 is retracted to lower the height of the sweeping brush 27, increasing the contact pressure between the brush bristles and the ground and enhancing the sweeping force. If the dust is thin, the first push rod 23 is extended to raise the sweeping brush 27, reducing brush bristle wear and achieving on-demand adjustment.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
