Junk box is a term used by amateur radio operators (hams) to describe a collection of spare parts and old equipment kept to assist in building and repairing their station. Typical items found in a junk box are electronic components such as resistors and capacitors as well as small parts such as screws, nuts and bolts. A junk box may also contain surplus, cast off or used electronic gear. Radio amateurs who construct their own equipment, known as homebrewers, often have large or well stocked junk boxes.

Garbage classification tracing method and device, storage medium and terminal equipment

The invention discloses a garbage classification tracing method and device, a storage medium and terminal equipment. The method comprises the following steps: when detecting that garbage is placed toa cover plate of a garbage bin, acquiring the weight of the garbage by an electronic metering device of the cover plate; receiving identity label information of a garbage throwing person who throws the garbage by an identifying device; controlling the cover plate to rotate so as to enable the garbage to drop into the garbage bin; taking the acquired weight of the garbage as a garbage identification number, and associating the garbage identification number with the identity label information of the garbage throwing person during storage; when detecting that garbage classification is wrong, acquiring the weight of the wrongly classified garbage by the electronic metering device arranged on the cover plate; finding the identity label information of the garbage throwing person associated withthe weight according to the weight of the wrongly classified garbage; and informing the garbage throwing person corresponding to the found identity label information about the information of wrong garbage classification. By an embodiment of the invention, garbage classification information tracing is realized, and the garbage classification tracing method and device facilitate garbage throwing persons, and are convenient to popularize.

InactiveCN101392506AMeet the uncertain long-term continuous operation needsMeet power needsRoad cleaningTransfer caseVehicle frame
The invention relates to a hybrid vacuum sweeper. A chassis is provided with an engine, a gear transfer case, a silicon rectifying generator, a storage battery, a power converter, a motor, a dustbin, a suction tube, a suction cup, a fan, a water tank and a water pump. The engine drives the silicon rectifying generator and the fan respectively. The silicon rectifying generator is connected with the power converter and the storage battery to output generated electric current. The power converter is connected with the motor to drive a rear axle shaft to drive the vacuum sweeper to run. The fan sucks dust and garbage on the ground in front of the suction cup into the dustbin through the dustbin, the suction tube and the suction cup. The water pump pumps water from the water tank to control the dust in the suction tube and the suction cup by a wet method. In the invention, a hybrid drive technology is applied to a special urban environment sanitary vehicle with vehicle-mounted operating devices, and the special vehicle has an oil-saving effect due to the use of a single engine as well as good operation effects; and a hybrid drive mechanism continuously generates electricity and overcomes the drawback that an electrical vehicle can not work for a long time due to the limitation from the capacity of the storage battery.
