Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel frame greenhouses, in particular to a multi-span steel frame greenhouse capable of sheltering from rain, ventilating and rapidly cooling down. Background Art
[0002] The steel frame greenhouse is a frame-covered structure with excellent thermal insulation performance. It allows people to eat off-season vegetables. Generally, the steel frame greenhouse uses a steel structure skeleton, which is covered with one or more layers of thermal insulation plastic film to form a greenhouse space. The outer film can effectively prevent the heat loss inside the greenhouse, so that the greenhouse has a good thermal insulation effect.
[0003] Steel frame greenhouses need to be ventilated and cooled in hot weather. Existing steel frame greenhouses are ventilated through shoulders set at both ends of the top. The shoulder vents enable the steel frame greenhouse to be ventilated and cooled quickly. However, on rainy days, in order to prevent rainwater from entering the greenhouse and causing crop diseases, the shoulder vents need to be closed and opened again after the rain stops. The shoulder vents need to be opened and closed repeatedly, which is time-consuming and laborious, and increases the difficulty of operation for users. Secondly, steel frame greenhouses are generally only provided with one layer of outer film, and the temperature inside the greenhouse is lower in winter, so that the yield of vegetables grown inside the greenhouse is not high, and artificial heating is required. For this reason, we provide a multi-span steel frame greenhouse that can shelter from rain, ventilate and cool down quickly to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a multi-span steel frame greenhouse which can shelter from rain, ventilate and cool down quickly. Through the coordinated arrangement of double ventilation components and inner membrane heating components, the problems in the prior art that multi-span steel frame greenhouses need frequent opening and closing of shoulder ventilation in the rainy season and artificial heating of the greenhouses in winter are solved.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a multi-span steel frame greenhouse that can be used for rain shelter, ventilation and rapid cooling, comprising a steel frame, a double ventilation component and an inner membrane heating component, the top of the steel frame is fixedly connected to a roof steel frame, and a support rod is fixedly connected between the bottom of the roof steel frame and the steel frame;
[0007] The dual ventilation assembly is arranged on the top of the steel frame of the shed roof, and comprises a support frame, a film is fixedly connected to the left side of the support frame, a first film roll is fixedly connected to the right side of the top of the steel frame, and second film rolls are fixedly connected to both sides of the top of the steel frame;
[0008] The inner membrane warming component is arranged in the inner cavity of the steel frame, and includes an inner membrane rod. Both sides of the inner membrane rod are fixedly connected to the inner wall of the steel frame, both sides of the top of the inner membrane rod are provided with a third film rolling device, and both sides of the bottom of the inner membrane rod are fixedly connected with support rods.
[0009] The utility model is further configured such that the bottoms of both sides of the inner cavity of the steel frame are fixedly connected with temperature sensors, and the top of the inner cavity of the steel frame is fixedly connected with reinforcement columns.
[0010] The utility model is further configured that a sealing door is movably connected to the front surface of the steel frame through a hinge, and a handle is fixedly connected to the front side of the sealing door.
[0011] The utility model is further configured such that both sides of the bottom of the support rod are fixedly connected with suspension rods, and the top of the suspension rod is fixedly connected to the roof steel frame.
[0012] The utility model is further configured such that the left side of the film is fixedly connected to the steel frame of the roof, and the film cooperates with the support frame to form a curved arch with an inclined surface.
[0013] The utility model has the following beneficial effects:
[0014] 1. The utility model adopts the setting of double ventilation components, and the opening on the right side of the support frame can be opened or closed by the first film roll, and the openings on both sides of the top of the roof steel frame can be opened or closed by the second film roll. When the weather is hot, the second film roll and the first film roll can be opened to open the openings on both sides of the top of the roof steel frame and the opening on the right side of the support frame, so that the interior of the greenhouse can be quickly ventilated and cooled. When it rains, the second film roll can be closed, leaving only the opening of the support frame for ventilation. The inclined design of the opening of the support frame prevents rainwater from entering the interior of the greenhouse, which is convenient for users to ventilate and dissipate heat in the greenhouse.
[0015] 2. The utility model, through the setting of the inner film warming component, can install the inner film rod inside the steel frame and lay the inner film, so as to increase the temperature inside the greenhouse in winter, increase the temperature inside the greenhouse and improve the crop yield. Secondly, the third film roller is also arranged on both sides of the top of the inner film rod, and the inner film opening can be opened when the greenhouse needs to be ventilated to facilitate ventilation, and the user does not need to perform artificial auxiliary heating on the inside of the greenhouse in winter.
[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
