DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 6 The present embodiment provides a technical solution: a solar greenhouse, comprising a shed body 1, a plastic film 11 is installed on the shed body 1, a reinforcing rib 12 is installed on the top of the shed body 1 and located on the upper part of the plastic film 11, a mounting seat 2 is connected to the reinforcing rib 12, the upper part of the mounting seat 2 is connected to a first rack 21 and a cylinder 27, a slide rod 25 is slidably connected in the cylinder 27, a connecting seat 23 is hinged on the top of the slide rod 25, a solar panel 22 is connected to the top of the connecting seat 23, and a first gear 24 meshing with the first rack 21 is connected to the middle part of the connecting seat 23; when the solar panel 22 is pressed by snow, the slide rod 25 slides into the cylinder 27, and the first gear 24 rolls on the first rack 21, so that the solar panel 22 changes from a horizontal state to a vertical state.

[0032] The solar panel 22 is installed on the top of the shed 1, and the solar panel 22 is slightly inclined, and its light-receiving surface faces the south. When it snows in winter, snow accumulates on the solar panel 22, thereby increasing the pressure on the solar panel 22. As the snow accumulates, the weight of the solar panel 22 gradually increases, so that the pressure applied to the slide bar 25 gradually increases. As the pressure increases, the slide bar 25 can slide down into the cylinder 27, so that the slide bar 25 drives the solar panel 22 to move downward. Since the first gear 24 connected to the lower part of the solar panel 22 is meshed with the first rack 21, the first gear 24 can roll on the first rack 21, so that the solar panel 22 swings from a horizontal state to a vertical state, and then the snow accumulated on the solar panel 22 slides off, thereby preventing the solar panel 22 from being damaged by the pressure of the snow.

[0033] Here, an electric telescopic rod can be arranged between the slide bar 25 and the cylinder 27 to cooperate with a pressure sensor to sense the pressure on the solar panel 22 to trigger the electric telescopic rod to shorten so that the slide bar 25 slides down.

[0034] A vertical groove 251 is provided on the side wall of the slide bar 25, and a convex plate 252 is provided in the vertical groove 251. A first limit pin 26 is slidably connected to the side wall of the cylinder 27, and a tension spring 261 is connected between the pin cap of the first limit pin 26 and the outer wall of the cylinder 27. The end of the first limit pin 26 is provided with a rounded corner, and one end located at the rounded corner is inserted into the vertical groove 251; when the solar panel 22 is under pressure, the slide bar 25 moves downward to make the convex plate 252 push the rounded corner, so that the first limit pin 26 is located on the upper part of the convex plate 252 after axial sliding, so that the slide bar 25 slides into the cylinder 27.

[0035] When the solar panel 22 is not compressed by snow, the force of the tension spring 261 acting on the first limit pin 26 can make the first limit pin 26 abut against the lower part of the convex plate 252. When the solar panel 22 is compressed by snow, the pressure applied to the first limit pin 26 by the slide bar 25 through the convex plate 252 gradually increases, so that the convex plate 252 slides along the rounded corner of the end of the first limit pin 26 to push the first limit pin 26 to slide away from the slide bar 25. After the convex plate 252 slides to the lower part of the first limit pin 26, the end of the first limit pin 26 with the rounded corner continues to slide in the vertical groove 251. The setting of the vertical groove 251 reduces the downward resistance of the slide bar 25. After the snow stops, the slide bar 25 can be manually pulled up to reset the solar panel 22. In addition, other power can also be used to drive the slide bar 25 to move upward relative to the cylinder 27.

[0036] A second limit pin 28 is vertically slidably connected to the bottom of the cylinder 27, and a first spring 29 is connected between the pin cap of the second limit pin 28 and the bottom wall of the cylinder 27; after the slide bar 25 slides down, it hits the pin cap of the second limit pin 28 so that the first spring 29 contracts and then extends, so that the slide bar 25 slides vertically back and forth in the cylinder 27, and the first gear 24 rolls back and forth on the first rack 21, so that the solar panel 22 swings back and forth.

[0037] Due to the setting of the vertical groove 251, the sliding resistance of the slide bar 25 is reduced, so that when the slide bar 25 slides down, it can hit the pin cap of the second limit pin 28, so that the first spring 29 is compressed, and then the compressed first spring 29 rebounds, so that the slide bar 25 slides up again, so that the slide bar 25 can slide back and forth vertically, so that the solar panel 22 swings back and forth, so that the snow accumulated on the solar panel 22 is shaken off, and the setting of the first spring 29 of the porcelain bowl also alleviates the sliding impact of the slide bar 25, preventing the solar panel 22 from being damaged by strong vibration.

[0038] The reinforcing rib 12 and the shed body 1 are respectively connected with a first rotating seat 32 and a second rotating seat 33, to which a first rotating roller 321 and a second rotating roller 331 are respectively rotatably connected, and a transparent conveyor belt 34 is transmission-connected between the first rotating roller 321 and the second rotating roller 331. When the first rotating roller 321 and the second rotating roller 331 rotate, the transparent conveyor belt 34 can transport the accumulated snow to the lower part of the shed body 1.

[0039] On snowy days, in order to prevent the accumulated snow from pressing on the plastic film 11 and causing damage to the shed body 1, a transparent conveyor belt 34 is further provided on the upper part of the plastic film 11. The setting of the transparent conveyor belt 34 allows light to enter the interior of the shed body 1 without obstruction. When snow falls and accumulates on the transparent conveyor belt 34, the first roller 321 and the second roller 331 are controlled to rotate, so that the transparent conveyor belt 34 runs, so that the accumulated snow falling on the transparent conveyor belt 34 is transported from the top to the bottom of the shed body 1 by the transparent conveyor belt 34, thereby preventing the shed body 1 from collapsing and being damaged due to the pressure of the accumulated snow.

[0040] A first support plate 3 and a second support plate 31 are connected to the shed body 1 . The first support plate 3 is located inside the annular space of the transparent conveyor belt 34 , and the second support plate 31 is located at the lower part of the transparent conveyor belt 34 .

[0041] The first support plate 3 and the second support plate 31 support the upper part of the annular space and the entire bottom of the transparent conveyor belt 34, so that the transparent conveyor belt 34 does not contact the plastic film 11, thereby preventing the transparent conveyor belt 34 from wearing the plastic film 11 during operation.

[0042] A heating water tank is arranged inside the shed body 1 , and a hot water pipe 44 is connected to the heating water tank. The hot water pipe 44 is distributed inside the shed body 1 , and the heating water tank is powered by the solar panel 22 .

[0043] The heating water tank uses the electricity generated by the solar panel 22 to heat the water. The heated water is pumped by a water pump to circulate in the hot water pipe 44. The hot water pipe 44 is distributed in the shed body 1, thereby heating the internal space of the shed body 1. The operation of the water pump is started by sensing the temperature in the shed body 1. The device used to sense the temperature in the shed body 1 can use a temperature sensor.

[0044] The end of the second roller 331 is connected to a second gear 58 via a one-way bearing. A second rack 57 meshing with the second gear 58 is vertically reciprocatingly slidably connected in the shed body 1. The second rack 57 can drive the second roller 331 to rotate in one direction when it vertically reciprocates.

[0045] When the second rack 57 slides down, under the action of the one-way bearing, the second rack 57 drives the second gear 58 to rotate relative to the second roller 331, and when the second rack 57 slides up, it can drive the second gear 58 and the second roller 331 to rotate, so that the second roller 331 can rotate in one direction, so that the snow accumulated on the top of the shed 1 is transported in one direction.

[0046] A water box 5 is vertically slidably connected in the shed body 1, a drain pipe 51 is connected to the middle part of the water box 5, a buckle tube 52 is connected in the water box 5, the buckle tube 52 is coaxially arranged with the drain pipe 51, and there is a gap between the top wall of the buckle tube 52 and the upper end of the drain pipe 51, an air pipe 53 is connected to the side wall of the buckle tube 52, and a second rack 57 is connected to the water box 5; a bottom plate 56 is connected in the shed body 1, a straight telescopic rod 54 is connected between the bottom plate 56 and the water box 5, a second spring 55 is sleeved on the straight telescopic rod 54, and the two ends of the second spring 55 are respectively fixedly connected to the water box 5 and the bottom plate 56; when water is gradually injected into the water box 5, the water box 5 is driven by gravity to move the second rack 57 downward, and when the water level in the water box 5 reaches the upper end of the drain pipe 51, the water in the water box 5 is discharged through the drain pipe 51 due to the siphon effect, so that the second spring 55 pushes the water box 5 to drive the second rack 57 to move upward.

[0047] The water box 5 is arranged near the lower part of the shed body 1 and is located at the position where the transparent conveyor belt 34 conveys the accumulated snow. The combination of the water box 5, the drain pipe 51, the buckle tube 52 and the air pipe 53 can generate a siphon effect when water or other liquids are injected into the water box 5 and the liquid level reaches the upper end of the drain pipe 51, so that the water or other liquids in the water box 5 are discharged through the drain pipe 51. When water is injected into the water box 5, the water box 5 can slowly move downward and after the water is discharged, it is pushed upward and reset by the second spring 55, so that the second rack 57 connected to the water box 5 can move up and down to drive the transparent conveyor belt 34 to transport the accumulated snow on the top of the shed body 1 to the lower part of the shed body 1.

[0048] A branch pipe 45 is connected to the hot water pipe 44 , and a drainage end of the branch pipe 45 faces the water box 5 .

[0049] The water discharged from the branch pipe 45 can be injected into the water box 5, and the water discharged from the branch pipe 45 is hot water, so that the water box 5 arranged at the snow discharge point can transfer heat to the discharged snow, so that the snow accumulated at the bottom of the shed body 1 can be partially melted, thereby avoiding a large amount of snow accumulation at the bottom of the shed body 1 affecting the conveying effect of the transparent conveyor belt 34 on the snow. In addition, when too much snow accumulates at the bottom of the shed body 1, the drainage end of the drainage pipe 51 can also be directed toward the accumulated snow, so that the discharged water directly flushes the snow transported by the transparent conveyor belt 34, further preventing a large amount of snow accumulation.

[0050] A control box 4 is provided at the connection position between the branch pipe 45 and the hot water pipe 44, and a rectangular plate 41 is vertically slidably connected inside the control box 4. A through hole 42 is opened on the rectangular plate 41, and a round rod 43 is connected to the top of the rectangular plate 41. When the second limit pin 28 moves downward, the round rod 43 can push the rectangular plate 41 downward so that the through hole 42 is connected to the hot water pipe 44 and the branch pipe 45; elastic cotton 46 is placed in the control box 4, and the elastic cotton 46 is arranged between the bottom of the rectangular plate 41 and the bottom wall of the control box 4.

[0051] After the slide bar 25 moves downward and squeezes the second limit pin 28 downward, the second limit pin 28 can push the round rod 43 to slide down, causing the rectangular plate 41 to move downward, so that the through hole 42 on the rectangular plate 41 is connected to the hot water pipe 44 and the branch pipe 45, so that hot water can flow into the water box 5 through the branch pipe 45, and the elastic cotton 46 makes it possible for the rectangular plate 41 to slide up supported by the deformation recovery of the elastic cotton 46 when the slide bar 25 moves upward and resets, so that the hot water pipe 44 and the branch pipe 45 are no longer connected.

[0052] It should also be noted that the temperature of all movable parts of the greenhouse is increased by electric heating to prevent the movable parts from being frozen and unable to operate in winter. The electric heating only acts on the movable parts, so that the accumulated snow can be removed from the top of the shed body 1, while avoiding the problem of increased energy consumption caused by the use of electric heating for the entire shed body 1.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
