Description

Technical Field

[0001] This invention relates to the field of environmental sanitation technology, and in particular to a method for village-level and community-level graded cleaning operations. Background Technology

[0002] With the acceleration of urban-rural integration, environmental sanitation and cleaning work in villages and communities is receiving increasing attention. The existing cleaning methods mainly adopt a "grid-based, assigned personnel and responsibilities" model, dividing responsibilities according to different areas such as roads, squares, green belts, and corridors, and implementing fixed-time and fixed-frequency cleaning standards.

[0003] In village-level sanitation, existing methods struggle to identify sudden pollution caused by the cyclical nature of agricultural production. During the summer and autumn harvest seasons, agricultural machinery entering and leaving villages brings out large amounts of soil and scattered straw. These pollutants, after being crushed by vehicles, form a stubborn layer that traditional scheduled cleaning methods are ineffective at removing, often requiring several times the manpower.

[0004] In community cleaning, existing methods cannot dynamically identify the high density of garbage generated instantly around square dance gathering points and garbage collection points after people finish their activities, leading to problems such as garbage being left overnight and breeding mosquitoes. Summary of the Invention

[0005] The purpose of this invention is to provide a village-level and community-level graded cleaning operation method, which aims to solve the problems existing in the prior art.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: A village-level and community-level tiered cleaning operation method includes the following steps: S1. An array-type pressure sensing unit is buried under the road surface at the entrance and exit of the village connecting farmland, and a humidity sensor is installed on the roadside. The array-type pressure sensing unit monitors the tire pressure distribution data generated when agricultural machinery passes through, and the humidity sensor monitors the humidity data of the soil carried by the tires. When the tire pressure distribution data exceeds a preset pressure threshold and the humidity data exceeds a preset humidity threshold, an agricultural machinery entry and exit characteristic signal is generated. S2. Receive the agricultural machinery entry and exit characteristic signal, and trigger the concealed high-pressure spraying system pre-embedded in the curb or median strip of the road section based on the signal to spray pre-wetting agent in a directional manner on the road surface area corresponding to the agricultural machinery driving trajectory, so as to change the interface bonding force between the subsequently fallen pollutants and the road surface. S3. A sweeper equipped with a variable hardness sweeping brush head is dispatched to enter the work section. In response to receiving the agricultural machinery entry and exit characteristic signal, the sweeper switches the sweeping brush head from the soft bristle state to the hard polymer bristle state and increases the pressure on the ground to perform mechanical stripping sweeping on the road surface that has been sprayed with pre-wetting agent. S4. A mechanical torque-sensing roller brush is installed at the rear of the sweeper. After sweeping, the roller brush rotates in contact with the ground and monitors the frictional resistance caused by residual pollutants in real time. When the frictional resistance exceeds the preset torque threshold, the sweeper is triggered to perform a second sweep of the current area and the area is marked as a high-pollution risk point based on the record of the second sweep.

[0007] As an improvement, in S1, the array-type pressure sensing unit generates a type characteristic signal of agricultural machinery by monitoring the tire pressure distribution and ground contact time, and the humidity sensor synchronously monitors the humidity value of the soil carried by the tire. When the type characteristic signal is a large harvester or tractor and the humidity value exceeds 30%, the agricultural machinery entry and exit characteristic signal is generated.

[0008] As an improvement, in S2, the concealed high-pressure spraying system responds to the agricultural machinery entry and exit characteristic signal and sprays a small amount only on the road surface area corresponding to the agricultural machinery driving trajectory identified by the array pressure sensing unit. The pre-wetting agent is an environmentally friendly surfactant used to reduce the adhesion coefficient between pollutants and asphalt or cement pavement.

[0009] As an improvement, in S3, the sweeper automatically adjusts the rotation speed and ground pressure of the sweeping brush head in response to receiving the agricultural machinery entry and exit characteristic signal, so that the hard polymer bristles make periodic contact with the road surface treated with pre-wetting agent, and peel off the crushed soil or straw attachment layer through physical shear force.

[0010] As an improvement, cleaning steps targeting community micro-environment hotspots are also included: photosensitive time-controlled switches are installed on lighting poles around community square dance gathering points or garbage collection points. These photosensitive time-controlled switches are connected in parallel with the community lighting circuit. When the lighting is turned on and the duration reaches a preset time, the photosensitive time-controlled switches automatically trigger a micro-mobile cleaning unit preset in that area to start a delayed cleaning operation. The micro-mobile cleaning unit is an automatically walking vacuum cleaning robot. After being triggered, the robot will patrol and clean along the edge of the green belt and around the seats, realizing a short-term closed loop between pollution generation and removal.

[0011] As an improvement, in S4, the mechanical torque sensing roller brush includes a driven roller brush in contact with the ground and a torque sensor connected to the driven roller brush. The torque sensor collects the resistance torque data when the roller brush rotates in real time. When the resistance torque data exceeds a preset threshold, it is determined that residual pollutants are present.

[0012] As an improvement, feedback adjustment is also included. When the area recorded in S4 is marked as a high-pollution risk point, the pre-wetting agent spraying time of the concealed high-pressure spraying system in step two is automatically extended when the agricultural machinery entry and exit characteristic signal of the area is received again.

[0013] As an improvement, in S1, the array-type pressure sensing units are buried in the road base layer in a grid pattern. Each sensing unit independently collects pressure data, and the driving direction and driving trajectory of agricultural machinery are identified by the pressure data change trajectory of multiple sensing units.

[0014] As an improvement, the concealed high-pressure spraying system includes a water supply pipeline buried inside the curbstone and nozzles facing the road surface. The spray angle of the nozzles is adjustable to cover the road width corresponding to the travel path of agricultural machinery.

[0015] As an improvement, the method is implemented using the following apparatus: Array-type pressure sensing unit: buried in the roadbed of the entrance and exit of the village connecting farmland, distributed in a grid pattern, used to independently collect tire pressure data and identify the type, direction of travel and trajectory of agricultural machinery; Humidity sensor: Installed on the roadside, it is used to monitor the humidity of the soil carried by the tires of agricultural machinery, providing a physical basis for determining whether soil pollution will occur. Photosensitive time control switch: Installed on the lighting poles around the community square and garbage collection room, connected in parallel with the lighting circuit, it is used to sense the end time of people's activities and trigger the cleaning command; Concealed high-pressure spraying system: pre-embedded in the curb or median strip, including water supply pipes buried inside the curb and nozzles facing the road surface. The system responds to sensing signals and sprays a small amount of pre-wetting agent in a directional manner on the road surface area corresponding to the driving trajectory of agricultural machinery. Variable hardness sweeping brush head: Equipped on the sweeper, it can automatically switch from soft bristle state to hard polymer bristle state according to the received pollution signal, and has a ground pressure adjustment function to remove pollutants whose adhesion has been reduced after pre-wetting treatment. Miniature mobile cleaning unit: An automatic walking vacuum cleaning robot pre-installed in hot spots of the community micro-environment, which performs real-time roving cleaning after being triggered by a photosensitive time control switch; Mechanical torque-sensing roller brush: Installed at the rear of the sweeper, it includes a driven roller brush in contact with the ground and a torque sensor connected to the driven roller brush, used to monitor the frictional resistance caused by residual pollutants in real time and verify the cleaning effect.

[0016] The beneficial effects of this invention are as follows: by burying array-type pressure sensing units and humidity sensors at the entrances and exits of village roads, it is possible to accurately identify the sudden pollution risks brought about by the cyclical activities of agricultural production. Instead of blindly cleaning at fixed times and frequencies, it generates characteristic signals based on physical signals such as the type of agricultural machinery and soil moisture, realizing the transformation from passive cleaning to active early warning and response, and greatly improving the pertinence and timeliness of responding to sudden pollution. In response to the high density of garbage generated by human activities such as community square dancing and around garbage collection points, the existing lighting circuits and photosensitive time-controlled switches are used as trigger signals. After the crowd disperses and the lights remain on for a period of time, the micro-sweeping unit is automatically triggered to perform a roving cleaning, which precisely solves the problem of garbage accumulating overnight. This is both energy-saving and environmentally friendly, and also achieves refined maintenance of the community environment. Detailed Implementation

[0017] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below in conjunction with the embodiments of this invention.

[0018] Example 1: Village-level sanitation operations It is applied to the main entrance and exit road section connecting farmland in a village.

[0019] An array of pressure sensing units is embedded in the road surface in a grid pattern. Each sensing unit independently collects pressure data. A humidity sensor is installed on the roadside. During the autumn harvest season, large harvesters drive from farmland into villages. When their tires pass over the road surface where the sensing units are embedded, the array of pressure sensing units detects that the tire pressure distribution exceeds 0.5 MPa and the ground contact time is consistent with the characteristics of agricultural machinery. The system generates a type characteristic signal indicating that it is a large harvester. At the same time, the humidity sensor detects that the humidity of the soil carried by the tires is 35% (exceeding the preset threshold of 30%). Based on the above physical signals, the system generates a characteristic signal of agricultural machinery entering and leaving the area.

[0020] The control system receives the characteristic signal of agricultural machinery entering and leaving, and immediately triggers the concealed high-pressure spraying system embedded in the curb of the road section. The system adjusts the nozzle angle according to the driving trajectory zone identified by the array-type pressure sensing unit, and sprays a small amount of environmentally friendly surfactant only on the noodle-like area corresponding to the two tire trajectory zones. This spraying operation is completed before the pollutants fall off, thus reducing the adhesion coefficient between the soil and the asphalt pavement in advance.

[0021] After receiving the signal indicating the entry and exit of agricultural machinery, the dispatch center dispatches a sweeper equipped with a variable hardness sweeping brush head to the work section. The sweeper responds to the signal and automatically switches the brush head from soft bristle mode to hard polymer bristle mode, increasing the ground pressure to 1.5 times that of conventional sweeping. As the sweeper travels along the road, the hard bristles mechanically peel and sweep the track area that has been sprayed with pre-wetting agent, effectively removing the compacted wet mud layer through physical shearing force.

[0022] After sweeping is completed, the mechanical torque-sensing roller brush installed at the rear of the vehicle rotates in contact with the ground. The driven roller brush and torque sensor inside monitor the resistance in real time. In a certain section of the track, the torque sensor detects that the frictional resistance exceeds the preset threshold, indicating that there are still residual pollutants. This signal triggers the sweeper to perform a second sweep in place until the torque value returns to normal, and the section is recorded as a high-pollution risk point. The next time an agricultural machinery entry or exit signal is triggered, the system will automatically extend the pre-wetting agent spraying time of that section.

[0023] Example 2: Community Cleaning Operations It is applied to the central square and surrounding areas of a city community.

[0024] Photosensitive time-controlled switches are installed on the lighting poles at square dance gathering points. These switches are connected in parallel with the community lighting circuit. The peak time for square dance activities is from 7:00 PM to 9:00 PM. When the lights are turned on, the photosensitive time-controlled switch detects that the lights have been on for a preset duration of 2 hours. At 9:10 PM, it automatically triggers a miniature mobile cleaning unit located at the edge of the green belt. This unit is an automatically walking vacuum cleaning robot. After being triggered, it starts a delayed cleaning operation, patrolling and cleaning along the edge of the green belt and around the seats. It promptly cleans up the instantaneous high-density garbage such as tissues and beverage bottles generated during the activities, realizing a short-term closed loop between pollution generation and removal, and preventing garbage from accumulating overnight.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
