Abstract
Description
Technical Field
[0001] This utility model relates to the field of urban waste management technology, specifically to a smart city waste sorting device based on the Internet of Things. Background Technology
[0002] Waste sorting, as a key measure to achieve urban waste reduction, resource recycling, and harmless treatment, is of great significance to promoting urban development. However, waste management is a global challenge. Current urban waste sorting facilities mainly rely on manual waste disposal, which is not only time-consuming and labor-intensive but also prone to misdisposal and indiscriminate dumping, further complicating subsequent waste treatment processes.
[0003] In current waste sorting and disposal practices, people often misclassify waste due to a lack of understanding of the specific classification standards. This misclassification not only leads to incorrect waste sorting but also significantly increases the complexity and difficulty of subsequent waste sorting and processing. To effectively address this issue, an IoT-based smart city waste sorting device is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a smart city waste sorting device based on the Internet of Things, which has the advantages of automatically identifying waste types, intelligently guiding sorting and disposal, improving sorting accuracy and work efficiency, and solving the problem of mis-disposal caused by disposers not knowing the types of waste, as well as the problem of increasing the difficulty of subsequent waste sorting and disposal.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a smart city waste sorting device based on the Internet of Things, comprising a base, a sorting component movably mounted on the top of the base, the sorting component comprising a top frame, an identification component fixedly mounted on the top of the top frame, a placement compartment fixedly mounted on the top frame below the identification component, temporary storage compartments fixedly mounted on both sides of the top frame, a reserved slot provided on the back of the temporary storage compartment, and a protective component provided on the temporary storage compartment; the protective component comprises a baffle, the baffle being rotatably mounted on the back of the temporary storage compartment, the bottom of the baffle passing through the reserved slot provided on the back of the temporary storage compartment and contacting but not fixedly connected to the front end of the inner wall of the temporary storage compartment.
[0006] Preferably, the base includes a column, on which a first trash can and a second trash can are rotatably mounted via a pivot on both sides. Lifting cylinders are fixedly mounted on the top of both sides of the column, and an insertion hole is provided on the top of the column.
[0007] The design incorporates a pivot for mounting the first and second trash cans, facilitating easy emptying by staff and significantly improving operational convenience. The lifting cylinder provides the power for subsequent adjustments to the height of the top frame in the sorting assembly, while the insertion holes ensure precise positioning for the connection and relative sliding between the top frame and the base, effectively guaranteeing the stability and flexibility of the overall structure.
[0008] Preferably, the first and second trash cans are located directly below the two temporary storage compartments, and both the first and second trash cans are lined with trash bags.
[0009] The design ensures that when trash falls from the temporary storage compartment into the trash can, it accurately lands inside the trash bag, effectively preventing trash from directly contacting the inner wall of the trash can and greatly reducing the difficulty of cleaning the trash can. At the same time, the trash bags are easy to replace, improving the efficiency of trash disposal and ensuring the hygiene of the system.
[0010] Preferably, the telescopic ends of the top of the two lifting cylinders are fixedly connected to the bottom of the front and back sides of the top frame, respectively, and the two lifting cylinders are interconnected and controlled by an independent switch.
[0011] The interconnected design ensures the stability of the top frame during lifting, while the independent switch control allows for flexible adjustment of the top frame height according to actual needs. For example, when the first or second trash can is full and the trash bag needs to be replaced, the lifting cylinder can be controlled by an independent switch to raise the top frame as needed, facilitating the replacement of the trash bag and significantly improving the convenience and adaptability of the device.
[0012] Preferably, a slide rod is fixedly installed at the bottom of the top frame, and the bottom of the slide rod is movably inserted into the insertion hole.
[0013] In the design, during the process of the lifting cylinder driving the top frame to rise and fall, the slide rod slides in the insertion hole, which plays a good guiding role and can ensure that the top frame rises and falls vertically. This effectively avoids the top frame from shaking during the lifting process and strongly guarantees the stability and reliability of the device operation.
[0014] Preferably, the identification component includes a waste type identification module, a sensor network, an IoT sensing layer, and a decision and control module. The waste type identification module is designed using a convolutional neural network model. The sensor network includes a metal sensor, an infrared sensor, and a color sensor. The IoT sensing layer is designed using Bluetooth wireless communication technology, or uses a wired network to send data to the cloud.
[0015] The waste type identification module, designed using a convolutional neural network model, can efficiently and accurately identify waste types. The sensor network, composed of metal sensors, infrared sensors, and color sensors, collects waste information from different dimensions, greatly improving the accuracy of identification. The diverse transmission methods of the IoT sensing layer allow for the selection of appropriate solutions based on actual scenarios, significantly enhancing the applicability of the device and the flexibility of data transmission.
[0016] Preferably, the protective component further includes a transmission roller driven by a stepper motor. The transmission roller is made of soft rubber and is installed with the baffle through friction. The stepper motor for driving the transmission roller is electrically connected to the decision and control module in the identification component.
[0017] In this design, the stepper motor precisely controls the rotation of the transmission rollers, which in turn precisely controls the opening and closing of the baffles, thus accurately guiding the disposal of waste. Because the stepper motor is electrically connected to the decision-making and control module within the identification component, the protective components can automatically respond based on the waste identification results, greatly improving the automation level and efficiency of waste sorting.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] The identification component in this invention employs advanced technology. The waste type identification module utilizes a convolutional neural network model, enabling efficient and accurate identification of waste types. Simultaneously, the sensor network includes metal sensors, infrared sensors, and color sensors, collecting waste information from different dimensions and significantly improving identification accuracy. The IoT sensing layer uses Bluetooth wireless communication technology or a wired network to send data to the cloud or decision and control module for analysis, accurately identifying waste types and achieving automatic waste type identification.
[0020] The stepper motor in the protective component is electrically connected to the decision and control module within the identification component. When the identification component identifies the type of waste, the decision and control module controls the stepper motor based on the identification result. The stepper motor precisely controls the rotation of the transmission roller, thereby precisely controlling the opening and closing of the baffle. If the waste is identified as belonging to the first waste bin, the protective component on the corresponding temporary storage compartment activates, the baffle rotates and opens, guiding the waste into the corresponding temporary storage compartment and falling into the waste bin below. Similarly, waste corresponding to the second waste bin can also be accurately guided for disposal, achieving intelligent guided sorting and disposal.
[0021] The identification component, leveraging advanced models and a multi-dimensional sensor network, can accurately identify waste types. Meanwhile, the protective component precisely controls the opening and closing of the baffles based on the identification results, guiding the waste accurately into the corresponding bins. This avoids mis-disposal caused by manual disposal due to a lack of understanding of the sorting standards, thus significantly improving sorting accuracy. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a smart city waste sorting device based on the Internet of Things, including a base 2, a sorting component 1 movably installed on the top of the base 2, the sorting component 1 including a top frame 14, an identification component 13 fixedly installed on the top of the top frame 14, a placement compartment 12 fixedly installed on the top frame 14 below the identification component 13, temporary storage compartments 11 fixedly installed on both sides of the top frame 14, a reserved slot is opened on the back of the temporary storage compartment 11, and a protective component 15 is provided on the temporary storage compartment 11; the protective component 15 includes a baffle 152, the baffle 152 is rotatably installed on the back of the temporary storage compartment 11, the bottom of the baffle 152 passes through the reserved slot opened on the back of the temporary storage compartment 11 and contacts the front end of the inner wall of the temporary storage compartment 11 but is not fixedly connected.
[0030] Specifically, the identification component 13 employs advanced technology. The waste type identification module utilizes a convolutional neural network model, enabling efficient and accurate identification of waste types. Simultaneously, the sensor network includes metal sensors, infrared sensors, and color sensors, collecting waste information from different dimensions and significantly improving identification accuracy. The IoT sensing layer uses Bluetooth wireless communication technology or a wired network to send data to the cloud or decision and control module for analysis, accurately identifying waste types and achieving automatic waste type identification.
[0031] The stepper motor in the protective component 15 is electrically connected to the decision and control module in the identification component 13. When the identification component 13 identifies the type of waste, the decision and control module controls the stepper motor according to the identification result. The stepper motor precisely controls the rotation of the transmission roller 151, thereby precisely controlling the opening and closing of the baffle 152. If the waste is identified as belonging to the first waste bin 22, the protective component 15 on the temporary storage compartment 11 corresponding to the first waste bin 22 is activated, the baffle 152 rotates and opens, guiding the waste into the corresponding temporary storage compartment 11 and falling into the waste bin below. Similarly, the waste corresponding to the second waste bin 23 can also be accurately guided for disposal, realizing intelligent guided classification and disposal.
[0032] The identification component 13, with its advanced model and multi-dimensional sensor network, can accurately identify the type of waste. On the other hand, the protection component 15 precisely controls the opening and closing of the baffle 152 based on the identification results, guiding the waste to fall accurately into the corresponding waste bin, avoiding mis-disposal caused by manual disposal due to a lack of understanding of the classification standards, thereby greatly improving the classification accuracy.
[0033] Example 2
[0034] To make it easier to remove the garbage bag after the trash can is full, such as Figure 4 As shown, in this embodiment, the base 2 includes a column 21. A first trash can 22 and a second trash can 23 are rotatably mounted on both sides of the column 21 via a rotating shaft 211. Lifting cylinders 213 are fixedly mounted on the top of the front and back sides of the column 21, and an insertion hole 212 is provided on the top of the column 21.
[0035] The first and second trash cans 22 and 23 are mounted via a pivot 211, facilitating the operation of emptying trash cans by rotating them, greatly improving ease of use. The lifting cylinder 213 provides the power for adjusting the height of the top frame 14 in the sorting component 1, while the insertion hole 212 provides precise positioning for the connection and relative sliding between the top frame 14 and the base 2, effectively ensuring the stability and flexibility of the overall structure.
[0036] Furthermore, the first trash can 22 and the second trash can 23 are located directly below the two temporary storage compartments 11, and both the first trash can 22 and the second trash can 23 are lined with trash bags.
[0037] The design ensures that when trash falls from the temporary storage compartment 11 into the trash can, it accurately lands in the trash bag, effectively preventing trash from directly contacting the inner wall of the trash can and greatly reducing the difficulty of cleaning the trash can. At the same time, the trash bag is easy to replace, improving the efficiency of trash disposal and ensuring the hygiene of the device.
[0038] Furthermore, the telescopic ends of the top of the two lifting cylinders 213 are fixedly connected to the bottom of the front and back sides of the top frame 14, respectively, and the two lifting cylinders 213 are interconnected and controlled by an independent switch.
[0039] The interconnected design ensures the stability of the top frame 14 during lifting, while the independent switch control allows for flexible adjustment of the height of the top frame 14 according to actual needs. For example, when the first trash can 22 or the second trash can 23 is full and the trash bag needs to be replaced, the lifting cylinder 213 can be controlled by the independent switch to raise the top frame 14 as needed, facilitating the replacement of the trash bag and significantly improving the convenience and adaptability of the device.
[0040] Furthermore, a slide rod 141 is fixedly installed at the bottom of the top frame 14, and the bottom of the slide rod 141 is movably inserted into the insertion hole 212.
[0041] In the design, during the process of the lifting cylinder 213 driving the top frame 14 to rise and fall, the slide rod 141 slides in the insertion hole 212, which plays a good guiding role and can ensure that the top frame 14 rises and falls vertically. This effectively avoids the top frame 14 from shaking during the lifting process and strongly guarantees the stability and reliability of the device operation.
[0042] Example 3
[0043] To improve the efficiency of waste sorting and identification, such as Figure 2 and Figure 3 As shown, in this embodiment, the identification component 13 includes a waste type identification module, a sensor network, an IoT sensing layer, and a decision and control module. The waste type identification module is designed using a convolutional neural network model. The sensor network includes a metal sensor, an infrared sensor, and a color sensor. The IoT sensing layer is designed using Bluetooth wireless communication technology, or it can use a wired network to send data to the cloud.
[0044] The waste type identification module, designed using a convolutional neural network model, can efficiently and accurately identify waste types. The sensor network, composed of metal sensors, infrared sensors, and color sensors, collects waste information from different dimensions, greatly improving the accuracy of identification. The diverse transmission methods of the IoT sensing layer allow for the selection of appropriate solutions based on actual scenarios, significantly enhancing the applicability of the device and the flexibility of data transmission.
[0045] Furthermore, the protective component 15 also includes a drive roller 151 driven by a stepper motor. The drive roller 151 is made of soft rubber and is installed with the baffle 152 through friction transmission. The stepper motor used to drive the drive roller 151 is electrically connected to the decision and control module in the identification component 13.
[0046] In this design, the stepper motor precisely controls the rotation of the transmission roller 151, thereby precisely controlling the opening and closing of the baffle 152 to accurately guide the disposal of waste. Because the stepper motor is electrically connected to the decision-making and control module within the identification component 13, the protection component 15 can automatically respond based on the waste identification results, greatly improving the automation level and efficiency of waste sorting.
[0047] When using this utility model, garbage bags are placed in the first garbage bin 22 and the second garbage bin 23 respectively to ensure that all components of the device are properly connected, the power is on, and the identification component 13, the protective component 15, and the lifting cylinder 213 are in a working state.
[0048] Personnel place the waste on the placement bin 12. The identification component 13 then begins operation. Its waste type identification module uses a sensor network to collect waste information and sends the data to the cloud or decision and control module for analysis via the Internet of Things (IoT) sensing layer to identify the type of waste. Based on the identification results, the decision and control module within the identification component 13 controls relevant components to guide the waste sorting process.
[0049] If the garbage is identified as belonging to the first garbage bin 22, the protective component 15 on the temporary storage compartment 11 corresponding to the first garbage bin 22 is activated. The stepper motor drives the transmission roller 151 to rotate, and the baffle 152 is rotated and opened by friction. At this time, the garbage is put into the current temporary storage compartment 11, and the protective component 15 is activated again to make the garbage fall into the first garbage bin 22 below. Similarly, if the garbage is identified as belonging to the second garbage bin 23, the protective component 15 on the temporary storage compartment 11 corresponding to the second garbage bin 23 is activated, causing the garbage to fall into the second garbage bin 23.
[0050] If trash needs to be removed due to a full trash can, two interconnected lifting cylinders 213 can be controlled by an independent switch. Their extension ends drive the top frame 14 to rise or fall, and the slide rod 141 slides accordingly in the insertion hole 212 to adjust to a suitable height, thereby allowing the trash bag in the first trash can 22 or the second trash can 23 to be rotated.
[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
