DESCRIPTION OF THE INVENTION In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative labor belong to the scope of protection of the present invention.

Referring to figures 1-7, for an intelligent classification garbage bin driven by photovoltaic by photovoltaic, solar panel 5, automatic classification system, activated carbon adsorption system, air sensor, storage tank and fire sprinkler, semiconductor refrigeration system, ultrasonic insect repellent 19and other equipment are added inside and outside the box. These devices are controlled by single chip microcomputer 27 to realize the automatic classification of garbage, so that the function of the garbage box 1s integrated, and the garbage box is completely powered by the off-grid photovoltaic power generation system to enhance the practicability of the garbage box.

The garbage bin in this application uses metal frame to construct the basic skeleton of the bin, and solar panels 5 are installed on the left, right, upper and rear sides, respectively, so as to achieve energy conservation and environmental protection and reduce the later operation cost. The material of the front surface of the bin is transparent flame retardant PVC plastic plate, which can directly see whether the garbage is overflowed, and it is convenient for sanitation workers to collect and empty. There are four separate bins in the box body: dry garbage bin 31, wet garbage bin 34, harmful garbage bin 32, recyclable garbage bin 33, and four separate bins can be removed by changing door 30.

Batteries and cigarette butts are put into a cigarette butt garbage box 21 and a waste battery box 22 through a throwing opening II 20 arranged on the box body.

The wet garbage bin 34 is made of metal materials, which has good thermal conductivity. The right wall of the inner surface of the wet garbage bin 34 is equipped with a temperature sensor 36. When the temperature in the garbage bin is detected to be too high, the single chip microcomputer 27 will drive the semiconductor cooler 35 below the outer front surface of the wet garbage bin 34 through the control circuit to cool down, inhibit the corruption of organic matter and reduce the smell. The temperature threshold can be set at 22 °C. At the same time, the hot end of the semiconductor cooler 35 can exopening the heat from the box through the heat dissipation device built in the system.

When there is a fire in the garbage bin, the closed glass ball nozzle 10 connected with the water storage tank 50 above the box body automatically senses and sprays to extinguish the fire, and the accumulated fire water is discharged from the garbage bin through the water outlet 39, on which a filter cloth is fixed, and the water in the water storage tank 50 is added through the water injection opening 12.

The first throwing opening 16 and the second throwing opening IIO are sealed by movable anti-static PVC plates to avoid static electricity generated during throwing, and the first throwing opening I6 and the second throwing opening IIO are closed by their own gravity when no one throws garbage.

A storage battery 1, a solar controller 3 and an inverter 2 are placed in the upper left corner below the box body, which together with a solar panel 5 form an off-grid photovoltaic power generation system, providing SV, 12V and 220V power supplies for the box body, and storing redundant electric energy, which is convenient for normal power supply at night or cloudy days and providing emergency charging services for passers-by, reducing energy consumption and saving energy; The storage battery 1, the solar energy controller 3 and the inverter 2 are placed in the iron box 4, which plays a role in fire prevention and waterproof The 220V socket 9 and SVUSB interface 8 located at the upper left of the box can provide charging service for passers-by; Each circuit interface is wrapped with PVC electrical insulating tape and heat shrinkable tube, which plays a waterproof role.

The activated carbon adsorber 23 includes a square container 41, an exhaust fan 51, and an activated carbon bag 40. The gas sensor 6 located on the left side of the box body of the square container 41 can detect the air quality in the box. When excessive pollution of the air in the box is not detected, the MCU 27 instructs the activated carbon adsorber 23 to perform ventilation through a control circuit, and the ventilation frequency can be set to 6 minutes every 30 minutes. When excessive pollution is detected, The single chip microcomputer 27 can instruct the activated carbon adsorber 23 to carry out air exchange operation without time limit through the control circuit, and the original instruction will not be restored until the excessive pollution is relieved. The activated carbon can be taken out through the refueling door 30 for regular replacement, so as to ensure that the gas discharged outside the box has no peculiar smell.

The ultrasonic insect repeller 19 is normally opened to repel insects and rats around the garbage bin.

The sterilization lamp 7 located on the left side of the box body is controlled by the program of the single chip microcomputer 27, and the program can be set to work every 12 hours for 25 minutes to inhibit the reproduction of bacteria and the breeding and spread of viruses.

The camera 13 is located in the center above the box body, and a surface light source 14 with built-in photoresistors is installed below the camera 13. The surface light source 14 1s controlled by a single chip microcomputer 27, which provides the camera 13 with a constant total illumination intensity when the external light environment changes, ensuring that garbage recognition is not affected by light.

The light strip 11 located above the front surface of the box is controlled by a single chip microcomputer 27. When someone passes by at night, the single chip microcomputer 27 lights the light strip 11 through a photosensitive sensor 25 and a pyroelectric inductive switch 26.

Automatic separation function of this application: The rotary table 38 and the conveyor belt 17 are located in the middle and upper part of the right side of the box body, and the ultrasonic sensor 15 is installed right above the rotary table 38. When garbage is thrown in from the throwing opening I 16, it reaches the rotary table 38 along the garbage guide plate 37, and the inclination angle of the garbage guide plate 37 is 45 degrees. When the ultrasonic sensor 15 detects garbage on the rotary table 38, it sends a signal to the single chip microcomputer 27. After receiving the signal, the single chip microcomputer 27 drives the conveyor belt 17 to run at a constant speed through the control circuit, and at the same time, 1t adjusts the speed of the rotary table 38 through PWM, so that the rotary table 38 can rotate from slow to fast at a constant speed gradient. Because each garbage has different relative density, rotation radius and external surface friction coefficient. The radial resultant force of each garbage on the rotary table 38 1s different, so the order in which each garbage falls from the rotary table 38 1s different. Because the conveyor belt 17 continuously runs forward at a constant speed, a plurality of garbage can be separated. A liquid guide pipe 18 is connected under the conveyor belt 17 to guide the waste liquid in the garbage into the wet garbage bin 34.

When the steering gear I 45 rotates forward, it drives the two-fold pull rod I 44 to pull down the classification plate 42 to tilt it to the left; When the steering gear I 45 reverses, it drives the two-fold pull rod I 44 to push up the classification plate 42, so that it tilts to the right in reverse; When the steering gear II 46 rotates forward, it drives the two-fold pull rod II 52 to pull down the classification plate 42 to make it tilt forward; When the steering gear IT 46 reverses, it drives the two-fold pull rod II 52 to push up the classification plate 42 to make it reverse and tilt backward; Thereby realizing the front, back, left and right tilting of the classification plate 42.

Automatic classification function of this application: Collect garbage pictures, define them as dry garbage, wet garbage, toxic garbage and recyclable garbage according to their types, build a data set, build and train the convolution neural network model on the PC, and test the obtained neural network model. When the accuracy rate is higher than 91.5%, embed the neural network into the Raspberry Pi 28, and optimize and test the parameters on the Raspberry Pi 28. The image resolution can be set at 800 X 600, and the discrimination threshold can be set.

When the infrared sensor 24 located at the exit of the left end of the conveyor belt 17 detects garbage passing by, the infrared sensor 24 sends a signal to the Raspberry P1 28, which starts the camera 13, acquires the garbage image falling on the sorting platform 29, and runs the convolution neural network for image recognition. When the garbage belongs to recyclable garbage, the Raspberry Pi 28 controls the steering gear 1 45 to rotate forward, and the two-fold pull rod 1 44 pulls down the sorting plate 42 to tilt to the left, and the garbage falls into the recyclable garbage bin. When the garbage belongs to the harmful waste, the Raspberry Pi 28 controls the steering gear I 45 to reverse, and the two-fold pull rod I 44 pushes up the classification plate 42 to tilt to the right, and the garbage falls into the harmful garbage bin; When the garbage belongs to dry garbage, the Raspberry Pi 28 controls the steering gear II 46 to rotate forward, and the two-fold pull rod II 52 pulls down the classification plate 42 to tilt toward the inside of the box, and the garbage falls into the dry garbage bin; When the garbage belongs to wet garbage, the Raspberry Pi 28 controls the steering gear II 46 to reverse, and the two-fold pull rod II 52 pushes the classification plate 42 to tilt toward the outside of the box, and the garbage falls into the wet garbage bin, finally realizing the automatic classification of the garbage; The rotation angles of the first steering gear 45 and the second steering gear 46 are 45 degrees to ensure that the pushed and pulled sorting plate 42 can accurately slide garbage into each trash can; Raspberry Pi 28 refers to Raspberry Pi, which is called "Raspberry P1 28" in Chinese, abbreviated as RPi.
