Description

Technical Field

[0001] The present application relates to the technical field of greenhouse roof films, and specifically to a laminated greenhouse roof film for preventing snow accumulation. Background Art

[0002] Greenhouse roof film is a plastic film covering the top of greenhouses in facility agriculture, such as vegetable greenhouses and flower greenhouses. The greenhouse roof film is generally made of materials such as polyethylene or polyvinyl chloride. At the same time, the greenhouse roof film can effectively prevent the heat in the greenhouse from radiating outward. For example, at night, the heat radiated from the ground is reflected back into the greenhouse by the roof film, forming a relatively closed insulation space.

[0003] In the greenhouse roof membrane structure we are currently using, the top membrane needs to be installed on the top of the greenhouse, so that the top of the greenhouse can be protected by the top membrane. However, the top membrane will encounter different environmental conditions when protecting the top of the greenhouse. When there is rain and snow in the environment, the rain and snow will accumulate on the top membrane. If it is not handled for a long time, it will cause a certain degree of impact on the greenhouse.

[0004] Therefore, it is necessary to provide a kind of anti-snow laminated greenhouse roof film to solve the above problems. Summary of the invention

[0005] Based on the above-mentioned problems existing in the prior art, the problem to be solved by the present application is: to provide a laminated greenhouse roof membrane that can prevent snow accumulation, so as to achieve the effect of quickly clearing the snow accumulated on the greenhouse roof membrane, thereby solving the problem that the accumulated snow may cause pressure damage to the greenhouse roof membrane.

[0006] The technical solution adopted by the present application to solve its technical problems is: a laminated greenhouse roof film for preventing snow accumulation, including a greenhouse assembly, on which a membrane assembly is fixedly installed, the greenhouse assembly includes a main body, on which a main beam is fixedly installed, an opening is opened on the main beam, an auxiliary beam is hinged on the main beam, the main beam and the auxiliary beam are respectively inclined downward, and the auxiliary beam can be flipped and adjusted on the main beam, the membrane assembly includes a top membrane a fixedly installed on the main beam, a top membrane b hinged on the top membrane a and a top membrane c fixedly installed on the auxiliary beam, the top membrane b and the top membrane c can be adjusted by the auxiliary beam, and a driving module is installed on the auxiliary beam, and the driving module is used to adjust the top membrane b and the top membrane c.

[0007] Furthermore, a plurality of groups of card blocks are fixedly installed on the top membrane b and the top membrane c, and pull ropes are fixedly installed between the card blocks. The pull ropes have a certain elasticity and are used to connect the top membrane b and the top membrane c.

[0008] Furthermore, the driving module includes a fixed plate a fixedly mounted on the main beam, a rotating rod is rotatably connected to the fixed plate a, a motor is fixedly mounted on the rotating rod, a fixed frame is fixedly mounted on the motor, the fixed frame is fixedly connected to the main beam, a gear is fixedly mounted on the outer side of the rotating rod, and a movable block is movably mounted on the bottom of the auxiliary beam, a rack is movably mounted on the bottom of the movable block, and the gear and the rack are meshed with each other.

[0009] Furthermore, a fixing block is provided on the outer side of the gear and the rack, and the fixing block is used to combine the gear and the rack. A fixing plate b is fixedly installed on the fixing block, and the fixing plate b is fixedly connected to the main beam, and the fixing plate b is used to fix the fixing block.

[0010] Furthermore, a support wheel is provided inside the fixed block, the support wheel can contact the outer side of the rack, and the support wheel can roll when the rack moves.

[0011] Furthermore, a sleeve a and a sleeve b are fixedly installed on the support wheel, a spring is fixedly installed between the sleeve a and the sleeve b, and there is an elastic effect between the sleeve a and the sleeve b.

[0012] Furthermore, guide plates are fixedly installed at both ends of the main body, and the guide plates are downwardly inclined.

[0013] The beneficial effects of this application are:

[0014] The present application provides a laminated greenhouse roof film for preventing snow accumulation, in which the main beam is inclined, so that the snow accumulated on the main beam can be discharged downward through the inclination angle of the main beam, so that the snow can be cleared to a certain extent, and the top film b and the top film c can be flipped at an angle, so that the position of the top film b and the top film c can be adjusted, thereby allowing the top film b to further improve the discharge efficiency of the accumulated snow. At the same time, through the adjustment angle of the top film b and the top film c, the greenhouse assembly can flexibly control the amount of sunlight incident, ventilation, and rainwater inflow, etc.

[0015] The present application provides a snow-proof laminated greenhouse roof film, which can be flipped at an angle on the main beam through the top film c, so that a part of the opening on the main beam can be exposed, so that the interior of the greenhouse assembly can be effectively ventilated. For example, when the temperature is high during the day, by flipping the top film c at a certain angle, the hot air will rise due to its lower density and be discharged from the opening. At the same time, the cold air from the outside will enter the interior of the greenhouse assembly through this opening, forming natural ventilation, thereby adjusting the temperature and humidity inside the greenhouse assembly, making the environment inside the greenhouse assembly more suitable for the growth of crops.

In addition, the driving method between the gear and the rack has a relatively strong bearing capacity compared to other driving methods. Even if the roof film area is large and the weight is heavy, the angle adjustment can be effectively achieved.

[0017] The present application provides a snow-proof laminated greenhouse roof membrane, which is provided with a support wheel so that the support wheel can roll when the rack is transmitted on the gear, thereby ensuring the smoothness of the rack transmission, and a spring is provided on one side of the support wheel so that the support wheel can always be located on one side of the rack, thereby allowing the support wheel to limit the rack, thereby ensuring the meshing stability between the gear and the rack.

DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] like Figure 1-Figure 7 As shown, the present application provides a laminated greenhouse roof membrane for preventing snow accumulation, including a greenhouse assembly 10, which can be installed on the ground. The greenhouse assembly 10 can create a suitable climate environment for the crops inside. At the same time, a membrane assembly is arranged on the greenhouse assembly 10, which can protect the top of the greenhouse assembly 10.

[0032] The greenhouse assembly 10 includes a main body 11, and a main beam 12 is fixedly installed on the main body 11, and an auxiliary beam 13 is hinged on the main beam 12. At the same time, the main beam 12 and the auxiliary beam 13 are respectively inclined downward, so that the accumulated snow or rainwater on the main beam 12 can be discharged downward by the gravity generated by the inclination angle of the main beam 12 and the auxiliary beam 13, so that the accumulated snow can be cleared to a certain extent, and the overall shape of the main beam 12 and the auxiliary beam 13 can have a certain curvature.

[0033] The membrane assembly includes a top membrane a14, which is fixedly mounted on the main beam 12, and a top membrane c16 is fixedly mounted on the auxiliary beam 13. At the same time, a top membrane b15 is hinged on the top membrane a14. The three groups of structures are made of the same material. At the same time, the three groups of structures are tilted by the inclination of the main beam 12 and the auxiliary beam 13, and the three groups of structures are adapted to the shapes of the main beam 12 and the auxiliary beam 13. The three groups of structures can effectively isolate the outside from the inside of the greenhouse assembly 10, thereby protecting the inside of the greenhouse assembly 10.

[0034] In addition, an opening is provided on the main beam 12, and the opening is initially covered by the auxiliary beam 13, so that the opening of the main beam 12 can be sealed by the auxiliary beam 13. Since the auxiliary beam 13 is hingedly installed on the main beam 12, the auxiliary beam 13 can be flipped and adjusted on the main beam 12, and a driving module is installed on the auxiliary beam 13, which can automatically adjust the auxiliary beam 13 so that the opening of the main beam 12 can be exposed to the outside, so that the interior of the greenhouse assembly 10 can be effectively ventilated. For example, when the temperature is high during the day, by flipping the top film c16 to a certain angle, the hot air will rise due to its low density and be discharged from the opening. At the same time, the cold air from the outside will enter the interior of the greenhouse assembly 10 through this opening, forming natural ventilation, thereby adjusting the temperature and humidity inside the greenhouse assembly 10, making the environment inside the greenhouse assembly 10 more suitable for the growth of crops.

[0035] At the same time, several groups of card blocks 17 are fixedly installed on the top membrane b15 and the top membrane c16, and pull ropes 18 are fixedly installed between the card blocks 17. At the same time, the pull ropes 18 have a certain elasticity. The pull ropes 18 are used to connect the top membrane b15 and the top membrane c16. The auxiliary beam 13 will drive the top membrane c16 to adjust synchronously when adjusting, and then the top membrane c16 can drive the top membrane b15 to adjust synchronously when flipping the angle, so that the angle of the top membrane b15 can be expanded. At this time, the accumulated snow on the top membrane b15 can be quickly discharged, and the accumulation of rain and snow on the membrane assembly can be avoided. At the same time, through the adjustment angles of the top membrane b15 and the top membrane c16, the greenhouse assembly 10 can flexibly control the amount of sunlight incident, ventilation and rainwater inflow.

[0036] The driving module is used to adjust the top membrane b15 and the top membrane c16, so that two groups of structures can be driven by one set of driving methods, which can significantly reduce the equipment procurement cost, and also reduce the time and energy investment in maintenance between structures, thereby reducing maintenance costs.

[0037] The driving module includes a fixed plate a123 fixedly mounted on the main beam 12, and a rotating rod 19 is rotatably connected to the fixed plate a123, and a motor 110 is fixedly mounted on the rotating rod 19, and a fixing frame 111 is fixedly mounted on the motor 110, and the fixing frame 111 is fixedly connected to the main beam 12, and the fixing frame 111 is used to fix the motor 110, and a gear 114 is fixedly mounted on the outer side of the rotating rod 19, and a movable block 116 is movably mounted on the bottom of the auxiliary beam 13, and a rack 115 is movably mounted on the bottom of the movable block 116, and the gear 114 and the rack 115 are meshed with each other, so that when the motor 110 is turned on, the rotating rod 19 and the gear 114 can be driven to rotate, and then the rack 115 can be moved at the position of the gear 114, so that the auxiliary beam 13 can achieve an angle flip.

[0038] At the same time, a fixing block 113 is provided on the outer side of the gear 114 and the rack 115, and the fixing block 113 is used to combine the gear 114 and the rack 115, so as to prevent the gear 114 and the rack 115 from deviating during operation. A fixing plate b112 is fixedly installed on the fixing block 113, and the fixing plate b112 is fixedly connected to the main beam 12, and the fixing plate b112 is used to fix the fixing block 113.

[0039] In addition, a support wheel 118 is provided inside the fixed block 113, and the support wheel 118 can contact the outer side of the rack 115, so that the support wheel 118 can roll when the rack 115 moves on the gear 114, thereby ensuring the smoothness of the transmission of the rack 115, and the support wheel 118 can limit the rack 115, thereby ensuring the meshing stability between the gear 114 and the rack 115.

[0040] The support wheel 118 is fixedly mounted with a sleeve a119 and a sleeve b120, and a spring 121 is fixedly mounted between the sleeve a119 and the sleeve b120, so that there is an elastic effect between the sleeve a119 and the sleeve b120. The elastic effect of the sleeve a119 and the sleeve b120 enables the support wheel 118 to perform partial shock absorption when limiting the rack 115, while also preventing the support wheel 118 from limiting the rack 115 too much and causing the rack 115 to get stuck, thereby improving the use stability between the gear 114 and the rack 115.

[0041] Finally, guide plates 122 are fixedly installed at both ends of the main body 11. The guide plates 122 are downwardly inclined, so that when the top film b15 discharges rain and snow on the surface downward, the falling rain and snow can be guided by the inclined guide plates 122, so that the rain and snow can be discharged to the two ends of the main body 11. Compared with discharging rain and snow to other positions inside the greenhouse assembly 10 or the middle part of the side, discharging it to the bottom of the two ends can minimize the damage to crops and interference with the space.

[0042] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
