by fixedly connecting the annular strip 131 to the heat-insulating film 13, the friction force between the heat-insulating film 13 and the roller 22 can be increased when the heat-insulating film 13 is rotatably connected with the roller 22, and the heat-insulating film 13 is prevented from slipping on the roller 22 when rotating; a human hand pushes the push-pull rod 151 to move upwards, the first connecting rod 152 and the second connecting rod 153 hinged on the push-pull rod 151 drive the two adjacent annular blocks 224 to move away from each other on the rotating shaft 24, the annular blocks 224 push the two adjacent rollers 22 to move away from each other on the rotating shaft 24, the rollers 22 drive the two adjacent heat-preservation films 13 to move away from each other, and finally, a gap is formed between the two adjacent heat-preservation films 13; due to the arrangement of the push-pull unit 15, the greenhouse can not only receive rainwater for irrigation in rainy days, but also better ventilate, so that plants in the greenhouse can perform aerobic respiration and photosynthesis, and the normal growth of the plants is ensured; snow falls in winter, falls onto the heat insulation film 13 on the outer side of the greenhouse, when snow accumulates to a certain weight, the heat insulation film 13 moves downwards under the pressure of the accumulated snow and finally contacts the second tripod 14, at the moment, the pressure sensor arranged on the second tripod 14 detects that pressure exists, the motor 21 is controlled by the controller to drive the rotating shaft 24 to rotate, and the rotating shaft 24 finally drives the heat insulation film 13 to rotate; through installing pressure sensor on No. two tripods 14 for drive unit 2 can be when snowing automatic operation, prevents that the unable condition that starts drive unit 2 in time and cause the big-arch shelter to be crushed when people from appearing the storm snow, has realized the promptness of the automatic snow removal of big-arch shelter, and the safety of the interior plant of guarantee big-arch shelter avoids causing economic loss.
Example 2: when the snow-removing greenhouse is used by a worker, when snow covers the greenhouse due to snowing, the driving unit 2 is started, the worker walks to the position below the driving unit 2, the pull rope 26 is pulled by the left hand and the right hand alternately, so that the pull rope 26 has a rotation characteristic on the outer wall of the rotating shaft 24, the rotating shaft 24 is driven by the pull rope 26 to rotate, the rotating shaft 24 drives the heat-preserving film 13 to rotate, the snow on the heat-preserving film 13 is separated from the surface of the heat-preserving film 13 in the rotating process, after the snow on the heat-preserving film 13 is cleaned up, the driving unit 2 is closed, and the greenhouse is started again when the next snowing is waited; the driving unit 2 is arranged, so that the effect that accumulated snow can be cleaned out of the surface of the heat preservation film 13 under the condition that power is not supplied to the greenhouse is achieved, the safety of plants in the greenhouse is guaranteed, and economic loss is avoided; the driving unit 2 brings the accumulated snow on the heat insulation film 13 to one side close to the snow box, the accumulated snow slides into the snow collection box 17 under the influence of the thrust of the heat insulation film 13 and the gravity of the accumulated snow, the accumulated snow slowly turns into water after the temperature of the accumulated snow is increased and melted, and the snow water flows through a pipeline 18 and is sprayed to plants in the greenhouse through a pressurized spray head 19; by collecting the accumulated snow covered on the greenhouse and then irrigating the plants in the greenhouse with the melted snow water, the green and environment-friendly irrigation mode not only saves water resources, but also ensures that the greenhouse part is crushed by the accumulated snow, and improves the safety performance of the greenhouse; each rotating shaft 24 connects the plurality of rollers 22 and the plurality of second tripods 14 in series, the rotating shaft 24 can drive the plurality of rollers 22 to synchronously rotate, and the second tripods 14 between each two rollers 22 enable the rollers 22 to move between the two second tripods 14; the second tripod 14 is arranged between every two rollers 22, so that the stability of the rotating shaft 24 during rotation can be improved; each roller 22 on the same rotating shaft 24 can drive the heat-insulating film 13 correspondingly connected in a rotating way to rotate; by arranging the multiple sections of heat-insulating films 13, only part of the heat-insulating films 13 need to be replaced when the heat-insulating films 13 are damaged, so that resources are saved, and the time for replacing the heat-insulating films 13 is shortened; the heat-insulating film 13 can drive the annular strips 131 to synchronously rotate when rotating, and the annular strips 131 circumferentially move along the first annular groove 221 formed in the roller 22; by fixedly connecting the annular strip 131 to the heat-insulating film 13, the friction force between the heat-insulating film 13 and the roller 22 can be increased when the heat-insulating film 13 is rotatably connected with the roller 22, and the heat-insulating film 13 is prevented from slipping on the roller 22 when rotating; a human hand pushes the push-pull rod 151 to move upwards, the first connecting rod 152 and the second connecting rod 153 hinged on the push-pull rod 151 drive the two adjacent annular blocks 224 to move away from each other on the rotating shaft 24, the annular blocks 224 push the two adjacent rollers 22 to move away from each other on the rotating shaft 24, the rollers 22 drive the two adjacent heat-preservation films 13 to move away from each other, and finally, a gap is formed between the two adjacent heat-preservation films 13; due to the arrangement of the push-pull unit 15, the greenhouse can not only receive rainwater for irrigation in rainy days, but also better ventilate, so that plants in the greenhouse can perform aerobic respiration and photosynthesis, and the normal growth of the plants is ensured;
