Detailed Description
As shown in fig. 1, the folding structure at the joint of the front and rear roofs of the shed film comprises a support rod 1, the shed film 2, a rotating point 3, a front roof framework 4, a rear roof circular arc framework 5 and a shed film and framework fixing structure 7. One end of the supporting rod 1 is welded at the top end of the circular arc-shaped framework 5 of the rear roof, and the other end of the supporting rod 1 is welded on the framework of the front roof, so that the supporting rod 1 is ensured to be folded towards the direction of the greenhouse film 2 when the variable sunlight greenhouse has the smallest roof angle. When current roofing skeleton motion, the greenhouse roof angle changes, and branch 1 will be folded to 2 directions of canopy membrane to fold canopy membrane 2, during the gap between roofing skeleton and the back roofing before preventing that canopy membrane can block when preceding roofing skeleton motion, influence structural stability.
As shown in fig. 2, the shed film folding structure at the joint of the shed film side wall and the framework comprises a supporting rod 1, a shed film 2, a rotating point 3, a side wall 6, a shed film and framework fixing structure 7, and a supporting rod and framework welding structure 8. One end of the supporting rod is welded at the top end of the circular arc-shaped framework of the rear roof, and on the other hand, the supporting rod is connected with the framework through a supporting rod welding structure, so that the supporting rod 1 is ensured to be folded towards the direction of the greenhouse film 2 when the corner of the front roof of the greenhouse is minimum. When the roofing angle changed before the greenhouse, branch 1 will be folded to 2 directions of canopy membrane to fold canopy membrane 2, during the gap between roofing skeleton and the side wall before the canopy membrane can block when preventing preceding roofing skeleton motion, influence structural stability.
As shown in fig. 3, the universal wheel structure at the joint of the pull rod and the side wall includes a pull rod 9, a universal wheel 10 and a side wall 6. The universal wheel 10 is fixed on the top end of the pull rod 9 and is tightly attached to the side wall 6. When the roofing angle changes before novel sunlight greenhouse, pull rod 9 will push up side wall 6 through universal wheel 10 and remove, prevents that novel greenhouse roofing rotation in-process in the front from producing the stability that the transverse force can't offset and influence the structure because of preceding roofing skeleton.
As shown in fig. 4, the front roof framework and foundation connection structure comprises an M10 hexagon bolt structure 11, an arc-shaped steel pipe 12, a foundation embedded part 13, an arc-shaped steel pipe outer sleeve 14, a ground plane 19 and a front roof framework 4. The front roof framework 4 is connected with the circular arc steel pipe 12 through an M10 hexagon bolt structure, the circular arc steel pipe outer sleeve 14 is sleeved outside the circular arc steel pipe 12, and the bending radians of the circular arc steel pipe outer sleeve and the circular arc steel pipe 12 are the same. The circular arc steel pipe 12 is welded on the basic embedded part 13. When the front roof framework rotates, the circular arc steel pipe 12 can rotate inside the circular arc steel pipe outer sleeve, so that the front roof can rotate and the front roof framework can rotate in the circular arc plane.
As shown in fig. 5, the gear and braking structure at the joint of the front roof and the rear roof comprises a gear 15, a circular arc gear strip 16, a braking device 17, a front roof framework 4, a rear roof circular arc framework 5 and a steel wire rope 24. When the front roof framework 4 is pulled to rise by the steel wire rope 24, the braking device 17 leaves the gear 15, and the gear 15 rotates along the circular arc-shaped gear rack 16. When the front roof angle reaches the preset angle, the front roof framework 4 stops lifting, the braking device 17 presses close to the clamping gear 15, the gear 15 is prevented from rotating up and down, and the front roof angle of the sunlight greenhouse is fixed.
As shown in fig. 6, the novel sunlight greenhouse with a variable front roof angle comprises a greenhouse foundation 18, a ground plane 19, an engine 20, a brick wall 21, a heat insulation board 22, a front roof framework 4 and a rear roof circular arc framework 5. When the greenhouse roof angle reaches the maximum roof angle, accumulated snow stays on a roof framework shed film before the greenhouse due to the reason of insufficient friction force and slides down, so that the accumulated snow is easily cleaned and the greenhouse is prevented from being collapsed by the accumulated snow.
As shown in fig. 7, the engine and chain transmission structure includes a fixed pulley 23, a wire rope 24, a rear wall 25, a front roof frame 4, a rear roof circular arc frame 5, and an engine 20. Two fixed pulleys 23 are respectively fixed at the top end of the circular arc-shaped framework 5 of the rear roof and the top end of the rear wall 25. When the angle of the greenhouse needs to be changed, the engine 25 rotates, and the steel wire rope transfers force through the fixed pulley 23 to enable the front roof framework 4 of the greenhouse to move, so that the change of the angle of the front roof of the greenhouse is realized.
