Through the arrangement of the shielding part and the movable part, the movable part drives the shielding part to move, the rotating block rotates and generates centrifugal force to make the accumulated snow above the shielding part fall off, the situation that the shielding part is deformed due to too much accumulated snow is avoided, and the safety and stability of the electric vehicle charging protection device are improved.

The invention relates to a single image snow removal method and system based on frequency domain enhancement multi-scale feature extraction and a medium, and the method comprises the following steps: obtaining an input image degraded by snow, inputting the input image into a pre-trained frequency domain enhancement-based snow removal model for processing, outputting a high-fidelity snow removal image, and carrying out the processing of the high-fidelity snow removal image; the frequency domain enhancement-based snow removal model comprises a resampling module and a plurality of channels, wherein each channel comprises an overlapped image block embedding module, a multi-scale feature extraction module, a Transform module and a snowless image reconstruction module which are connected in sequence. Compared with the prior art, attention can be dynamically adjusted so as to effectively cope with snowflake noise of different scales, and therefore the snow removing effect and the like are remarkably improved.

The utility model belongs to the technical field of greenhouses, and relates to a greenhouse capable of removing accumulated snow on the top of the greenhouse in a knocking mode, the greenhouse is in a closed state during knocking snow removal, and the greenhouse comprises a greenhouse main body and a knocking device; wherein a detonation framework is arranged in the greenhouse body in the longitudinal direction, a plurality of detonation points are arranged on the detonation framework at intervals, the detonation devices are installed and fixed to the detonation points, explosives in the detonation devices give out vibration brittle sound at the burning and explosion moment, and hot gas released at the burning and explosion moment acts on the greenhouse film. According to the greenhouse, the detonation device in the greenhouse is ignited, hot gas released by the detonation device at the burning explosion moment acts on the greenhouse film, the greenhouse film is instantly expanded and then is instantly restored to the original shape, accumulated snow on the greenhouse film is shaken off, the purpose of removing snow is achieved, and the greenhouse has the advantages that the snow removing effect is good, cost is low, and the service life of a greenhouse framework cannot be affected.

The application discloses a pressure-resistant snow-melting structure and snow-melting device, and relates to the technical field of road engineering snow-melting, which comprises a shell, a cavity is formed in the shell, and a bottom plate is detachably connected to the bottom of the shell; a support plate made of heat-conducting material is arranged in the cavity, a plurality of support plates divide the cavity into a plurality of chambers with equal volumes, and through holes are arranged at both ends of the support plate; an electric heating element is arranged in the cavity through one end of the shell, sequentially passes through the through holes of the support plates and is arranged outside the other end of the shell, so that the electric heating element is arranged in the cavity in an S shape. The application can achieve good snow-removing effect without affecting road driving, can be repeatedly recycled and used, has good durability, and is suitable for key sections of expressways, urban trunk roads, elevated bridges, airport runways and other areas requiring rapid snow-melting and high protection requirements for road surface structures.

The utility model discloses a novel snow blower, which relates to the technical field of snow blowers and comprises a mounting seat, a backup plate is fixedly mounted on one side of the top surface of the mounting seat, and a snow blower body is fixedly mounted in the middle of the top surface of the mounting seat. The electric heating wire in the heating box is powered through the battery, wind power generated when the snow blower body works is blown into the heating box through the air outlet pipe and is heated into hot air through the electric heating wire, the wind blown out of the air blowing pipeline is heated, a condensation layer at the bottom of a snow accumulation layer is removed, and the snow removal effect is improved; when the snow blower body needs to be used for removing snow, under the cooperation of the two straps and the backup plate, the device is carried on the back of a user, and the problems that most existing snow blowers are in a hand-held type, the user needs to carry the snow blower in the hand-held type for work during snow removal, the user is prone to overexerting arms after long-time use, and the snow blower is inconvenient to use are solved. And the practicability is poor.

This invention discloses a snowplow and sweeper integrated machine and a snow removal vehicle. The snowplow and sweeper integrated machine includes a main tilting frame, an angled assembly, and a shovel body assembly. The main tilting frame includes a hanging frame and a hinged frame. One side of the hanging frame is mounted on a carrier, and the other side is laterally rotatably connected to the hinged frame. The angled assembly includes an angled main frame, a brush assembly, and a lifting mechanism. One side of the angled main frame is longitudinally rotatably connected to the hinged frame, and the other side is equipped with the brush assembly, which is connected to the angled main frame via the lifting mechanism. The shovel body assembly includes a shovel body and a lifting mechanism. The shovel body is located in front of the brush assembly and is mounted on the angled main frame via the lifting mechanism. The lifting mechanism is used to lift the shovel body above the brush assembly. The snow removal vehicle includes the aforementioned snowplow and sweeper integrated machine.
