The invention discloses a three-dimensional thermoelectric device based on double-sided silk-screen printing and a preparation method thereof, and belongs to the technical field of new energy devices, the three-dimensional thermoelectric device is obtained by folding a two-dimensional layout structure for multiple times, and the two-dimensional layout structure is a double-sided structure prepared on a substrate by using a silk-screen printing process. Each face structure comprises a bottom electrode layer, an N-type thermoelectric material layer, a P-type thermoelectric material layer and a top electrode layer which are of an array structure in sequence. The N-type thermoelectric supporting legs and the P-type thermoelectric supporting legs are alternately arranged, and the N-type thermoelectric supporting legs, the P-type thermoelectric supporting legs and the top-layer electrode unit all have overlapping areas with the bottom-layer electrode unit; the two-dimensional layout structure is folded into a three-dimensional thermoelectric device through multiple folding, three-dimensional collection of heat flow can be achieved, the limited substrate area is fully utilized, and the three-dimensional thermoelectric device has the advantages of being high in output power density, compact in structure, high in integration degree and small in occupied area and is particularly suitable for wearable scenes.

The utility model discloses a kind of spraying devices for agricultural planting, it includes vehicle plate, the vehicle plate is provided with spraying water tank, both sides of the spraying water tank are equipped with spraying structure, and the spraying water tank is connected with supply water tank;Spraying structure includes a section of pipe, first hinged member, second hinged member, second section of pipe, connecting hose, third hinged member, third section of pipe and spraying nozzle, the section of pipe is located in the side of spraying water tank and is connected by first hinged member, the section of pipe is equipped with second hinged member and is connected with second section of pipe, the second section of pipe is equipped with third hinged member and is connected with third section of pipe, and connecting hose is connected between the section of pipe and second section of pipe and between second section of pipe and third section of pipe. The utility model is flexibly unfolded by the section of pipe, second section of pipe and third section of pipe, realize the flexible adjustment of spraying area, and then can adjust the area of spraying according to the specific width of planting ridge, reduce the limitation of spraying.

The utility model relates to the technical field of snow melting pads, and discloses a snow melting pad convenient to adjust, which comprises a plurality of snow melting pad bodies, power supplies are arranged in the snow melting pad bodies, one sides of the power supplies in the snow melting pad bodies are fixedly connected with a first connecting line and a second connecting line, and the other sides of the power supplies in the snow melting pad bodies are fixedly connected with the first connecting line and the second connecting line. The first connecting line and the second connecting line extend to the outside of the snow melting pad body. When the snow melting pad is used, the clamping groove in one side of one snow melting pad body is aligned with the extension pad of the other snow melting pad body and is pressed downwards, and the connector can be inserted into the round hole in the clamping groove, so that the two snow melting pad bodies are installed, the area of the snow melting pad is conveniently and flexibly adjusted, and the snow melting pad is convenient and rapid to use; the first plug at one end of the first connecting line is aligned with the second plug at one end of the second connecting line to be inserted, then the rotating ring is screwed outside the second plug, limiting can be carried out through the rotating ring, and the disengagement probability is reduced.

The apartment bed comprises a bed body, a clamping groove is formed in the bed body, a clamping plate is connected in the clamping groove in an abutting mode, a connecting plate is fixedly connected to the top of the clamping plate, a cylinder is fixedly connected to the top of the connecting plate, a connecting rod is connected in the cylinder in a sliding mode, and a screw hole is formed in the cylinder. The side face of the connecting rod is fixedly connected with a protective fence, a magnetic plate is fixedly connected in the protective fence, an iron plate is connected in the magnetic plate in a magnetic attraction mode, the iron plate is connected with the protective fence in a sliding mode, a groove is formed in the iron plate, and the top of the protective fence is fixedly connected with an illuminating lamp. According to the protective fence, the clamping plates and the clamping grooves are matched for use, the connecting plates can be detachably fixed to the side face of the bed body through the inserting function of the clamping plates and the clamping grooves, the protective fence can be conveniently used by an apartment bed, the iron plates can be correspondingly moved in the protective fence according to actual needs, and then the area of the protective fence is adjusted.

An auxiliary culture device for garden seedling culture belongs to the technical field of garden seedling culture and comprises a bottom frame, side frames are symmetrically arranged on the left side and the right side of the bottom frame, a plurality of first bedplates are mounted between the two side frames, a plurality of culture pots are placed on each first bedplate, a rotating rod is rotatably arranged at the top ends of the two side frames, and two supporting arms are fixedly mounted on the rotating rod. The device can flexibly adapt to crop cultivation requirements of different photophilous degrees as required by adjusting the position of the baffle plate, can adjust the inclination degree of the baffle plate and can also adjust the covering area under the condition of different angles of inclined irradiation of sunlight due to different longitudes and latitudes, so that the device is convenient to use. In addition, the two extension plates can be promoted to extend or retract into the inner cavity of the shielding plate, the positions of the extension plates do not need to be adjusted one by one, operation is quicker, and practicability and flexibility are achieved.
