The invention relates to the technical field of perovskite solar cell film preparation, in particular to a formamidino halide material cold deposition coating device and method.The formamidino halide material cold deposition coating device comprises a shell, an evaporation source and a substrate support, the evaporation source and a substrate are both located in the shell, a heating belt is embedded in the shell, the evaporation source is arranged in the center of the shell, and the substrate support is arranged on the substrate support; the heating belt and the evaporation source are subjected to temperature control in an independent electric heating mode; the substrate support is arranged around the evaporation source according to the design position of the cavity; a cooling structure is arranged in the substrate support, substrate clamps are arranged on the two faces of the substrate support, a substrate is fixed to the substrate clamps, and a rotating structure is arranged at the bottom of the substrate support. The interior of the shell further communicates with a vacuum pump. During use, the temperature of the shell is higher than that of the substrate support. According to the method, the formamidino halide material in a dispersed state is most easily deposited in a low-temperature region, and the preferential deposition and accurate control of the formamidino halide material can be realized by designing a variable-temperature and rotatable substrate device.

The utility model discloses a kind of pipe orifice protection structures, belong to pipeline installation technical field, including sleeve, the sleeve both sides are symmetrically fixed with support rod, two the support rod end portion are fixed with clamping block, the clamping block is provided with the protection assembly of avoiding pipe orifice abrasion pollution, the sleeve is provided with the support assembly of being connected to pipe orifice. The utility model utilizes protection cylinder rotation, so that clamping block is clamped into slot, so that protection cylinder is connected outside clamping block, so that pipe orifice is protected inside protection cylinder, avoid pipe orifice and external friction and produce abrasion and pollution, simultaneously, in the case where it is needed, gas nozzle can be filled with gas to inflate air bag, so that protection cylinder opening is plugged, so that dust is prevented from entering, can be further achieved to the purpose of protecting pipe orifice.

The utility model relates to the technical field of unmanned aerial vehicle inspection, and discloses an unmanned aerial vehicle inspection auxiliary device which comprises an unmanned aerial vehicle body, and a bottom plate is fixedly installed at the bottom of the unmanned aerial vehicle body. The camera is arranged below the bottom plate; the U-shaped seat is fixedly mounted on the lower surface of the bottom plate; the buffer mechanism is mounted on the U-shaped seat and is used for carrying out impact buffering on the camera; according to the unmanned aerial vehicle inspection auxiliary device, impact energy generated during high-speed landing of the unmanned aerial vehicle body can be effectively absorbed and dispersed, impact on precision equipment such as a fuselage and a camera is reduced, and therefore the risk of equipment damage is reduced, and the integrity and long-term stable operation of the unmanned aerial vehicle body and equipment carried by the unmanned aerial vehicle body are ensured; the direction and posture of the camera can be independently driven, accurate angle adjustment is carried out, images or videos in the specific direction can be captured, the adjustment process is more flexible and practical, and the actual use requirement is met.

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.
