The invention relates to a heat storage heat exchanger and an air supply system comprising same. The heat exchanger comprises a shell, a heat storage medium and a fluid passage, wherein the heat storage medium is arranged in the shell, the fluid passage is arranged in the heat storage medium, the fluid passage is provided with a fluid inlet and a fluid outlet, the heat storage capacity of the heat storage heat exchanger is S, the heat storage capacity S is set as a function which is x away from the fluid inlet, i.e. S=f(x), in the heat storage heat exchanger, f(x) is more than 0, and f(x) is a first derivative of f(x). The heat storage medium integrally and uniformly absorbs the heat in the flowing direction of the fluid, and the situation such as non-uniformity in heat absorption can be avoided.

The invention discloses a small wheel diameter pushable and liftable bicycle capable of being vertically folded. The bicycle comprises a front wheel, a rear wheel, a front fork, a rear fork, a front fork stand pipe, a handlebar rack, a bicycle frame, a saddle tube, a saddle seat and a driving mechanism, wherein the bicycle is integrally H-shaped; the front fork stand pipe and a handlebar vertical pipe are vertical, and the saddle tube is also vertical; a bicycle frame front tube and a bicycle frame rear tube are horizontally and transversely arranged to form one transverse line of the H-shaped bicycle; the bicycle frame front tube and the bicycle frame rear tube are hinged through a unidirectional rotation hinged joint positioned in the middle; the unidirectional rotation hinged joint rotates and is folded under the acting force of lifting; the bicycle is rectangle-shaped after being folded; after the bicycle is folded, the bicycle frame front tube and the bicycle frame rear tube are vertical, and the front wheel and the rear wheel are closed up and are positioned on the same straight line; after the bicycle is folded, the connecting line between the hinged shaft of the unidirectional rotation hinged joint and a front wheel axle and the connecting line between the hinged shaft of the unidirectional rotation hinged joint and a rear wheel axle form the two waists of an upright isosceles triangle. According to the bicycle, the structure of the overall bicycle can be simplified to the maximum extent, and the weight of the overall bicycle is reduced to the maximum limit.

The invention discloses a palletizer for stacking steel pipes, which comprises a steel pipe conveyor belt, a bottom plate, a palletizing mechanism, a material pushing mechanism and a magnetic suction device for steel pipes. The material pushing mechanism is composed of a pushing plate and a second electric telescopic rod. The palletizing mechanism includes multiple sets of support plates, limit frames, multiple sets of first fixed seats, multiple sets of limit rods and multiple sets of second fixed seats, and the steel pipe magnetic device includes a column, a motor, a rotating seat and a supporting Components, the material holding component includes a third electric telescopic rod, a first placement plate, an air cylinder and a second placement plate. The invention can effectively realize the magnetic fixation of the supporting part to the steel pipe through the electromagnetic attraction on the supporting part and the supporting part, and can effectively realize the connection between the elastic picking piece and the extrusion plate through the position of the elastic picking piece in the arc-shaped chute. contact, the steel pipes can be stacked one by one through the inclined support plate, and the steel pipes can be stacked layer by layer by adjusting the expansion and contraction of the first electric telescopic rod.
