Description

Technical Field

[0001] The utility model relates to the technical field of solar greenhouses, in particular to a novel greenhouse with convenient ventilation. Background Art

[0002] Solar greenhouse is the abbreviation of energy-saving solar greenhouse, also known as "warm shed". It is a relatively simple facility that makes full use of solar energy. In cold areas, vegetables are generally cultivated over the winter without heating. Greenhouses have been widely used in vegetable planting, flower cultivation, and seedling breeding.

[0003] Existing solar greenhouses are usually composed of gables on both sides, a rear wall, a supporting frame and covering materials. The gables and rear walls are generally built with earth walls or brick walls, and the slope is covered with a film quilt. This method has a certain heat storage and insulation capacity and can ensure normal production in winter. However, at the end of the hot second quarter and the entire third quarter, the temperature in the greenhouse is too high. Since temperature is not the only factor affecting the growth of greenhouse crops, good ventilation is also extremely critical. However, the existing solar greenhouses can only open vents at the top and bottom of the slope, which can only ensure ventilation in winter. The obstruction of the gables and rear walls results in poor ventilation, making the solar greenhouse unable to be used during the above time period and can only be idle, reducing the utilization rate of the solar greenhouse. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a new greenhouse with convenient ventilation.

[0005] The technical solution of this utility model is as follows:

[0006] A new greenhouse with convenient ventilation includes multiple arch rods arranged at intervals, the multiple arch rods are connected by multiple tie rods perpendicular to the arrangement direction of the arch rods, and multiple crisscrossing horizontal purlins and vertical purlins are arranged at the bottom of the arch rods at both ends.

[0007] One end of the arch rod is connected to a downwardly inclined connecting rod, and the bottom end of the connecting rod is connected to a vertical supporting rod, and the other end of the arch rod and the supporting rod are both installed on the ground;

[0008] The arch rod is covered with a film, the connecting rod and the outer sides of the horizontal purlin and the vertical purlin are fixedly covered with a first insulation layer, the outer side of the support rod is covered with a second insulation layer, and the bottom end of the second insulation layer can be rolled up through a rolling device.

[0009] In order to improve the insulation effect of the fixed first insulation layer on the greenhouse and facilitate the fixing of the first insulation layer, the upper end of the first insulation layer extends to the arch rod for fixing, and the lower end extends to the outside of the support rod to contact and fix with the second insulation layer.

[0010] In order to improve the stability of the contact portion between the first thermal insulation layer and the second thermal insulation layer, the contact portion between the first thermal insulation layer and the second thermal insulation layer is pressed tightly by a flat iron.

[0011] The specific structure of the winding device is that the winding device includes a roller shutter machine, the bottom end of the second insulation layer is fixed to the shutter rod, the roller shutter machine is connected to a telescopic rod, and the upper end of the telescopic rod is hinged to the support rod.

[0012] The telescopic rod and the support rod are hinged in such a manner that the support rod is connected with a bracket, and the bracket passes through the second thermal insulation layer, and the upper end of the support rod is hinged with the bracket.

[0013] In order to ensure the area of ​​the vents exposed after the second thermal insulation layer is rolled up and to ensure the ventilation effect, the length of the second thermal insulation layer is 1.8m-2.5m.

[0014] In order to improve the thermal insulation effect of the first thermal insulation layer and the second thermal insulation layer on the greenhouse, improve the wear resistance and ensure the service life of the thermal insulation layer, the first thermal insulation layer and the second thermal insulation layer are both made of PVC scraper cloth.

[0015] In order to be able to roll up both ends of the film so that the greenhouse can be ventilated at the top and front of the greenhouse, the film roller and the installation method of the film roller in the prior art can be used here. Film rollers are provided at both ends of the arch rod, and the two ends of the film are respectively connected to the winding shaft of the film roller.

[0016] The film roller is installed in such a way that the film roller at the upper end is hinged to the purlin through a connecting frame, and the film roller at the lower end is hinged to the ground through a connecting frame.

[0017] In order to limit the area of ​​the film being rolled up and ensure that one end of the film can be fixed, a film pressing piece perpendicular to its arrangement direction is provided at the bottom end of the arch rod. The film pressing piece is located outside the film and above the film roll to limit the rolling of the film.

[0018] The beneficial effects of the utility model are as follows: the utility model is a new type of greenhouse that is convenient for ventilation. Firstly, a plurality of arch rods cooperate with pull rods and other rods to form a frame structure of the greenhouse, and the greenhouse can be covered by a film and a first insulation layer and a second insulation layer, so that the greenhouse can absorb heat and simultaneously perform heat preservation and heat storage. Secondly, the two ends of the film can be rolled up by a film roller, so that vents can be formed at the upper end and the front end of the greenhouse, so that the greenhouse has a basic ventilation effect. The most critical thing is that a retractable second insulation layer is designed, so that the greenhouse can be rolled up at the rear end in hot seasons to form new vents, which can be connected with the vents at the front end and the upper end of the greenhouse, so that air can form convection, which greatly improves the ventilation effect of the greenhouse. Moreover, the dehumidification effect of the greenhouse can be improved by multiple vents, so that the solar greenhouse can be used normally in hot seasons, which improves the utilization rate of the greenhouse while ensuring the economic benefits of the growers.

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, the existing solar greenhouse is usually composed of three-sided walls and one-sided slope, and in order to meet the basic ventilation needs in winter, a rollable film 7 is set at the top and bottom of the slope, that is, the front end of the solar greenhouse, so that the greenhouse can expose two vents to perform ventilation and dehumidification work in the greenhouse. However, it can only meet the ventilation needs in winter. In seasons with higher temperatures, the temperature in the greenhouse is higher, and the walls will block the air, which cannot meet the normal growth of crops and causes the greenhouse to be idle. Therefore, the inventor has made improvements on the existing solar greenhouse and designed a solar greenhouse that is easy to ventilate, so that the greenhouse can be used all year round. The following is a detailed explanation with reference to the drawings.

[0030] This embodiment provides a new type of greenhouse that is convenient for ventilation. Figure 1 , including multiple arch rods 1 arranged at intervals, the arch rods 1 are in an upwardly curved shape and are arranged downwardly, and generally the lower end is south-facing, and the multiple arch rods 1 are connected by multiple tie rods 2 perpendicular to the arrangement direction of the arch rods 1 to form a framework for the entire slope. In order to support both sides of the greenhouse, multiple criss-crossing horizontal purlins 3 and vertical purlins 4 are arranged at the bottom of the arch rods 1 at both ends. The vertical purlins 4 are installed on the ground to form side supports for the greenhouse, and for the stability of the entire slope, columns should be arranged at intervals at the bottom of the middle arch rod 1 for support.

[0031] Based on the above support framework, combined with Figure 2 The rear support in this embodiment also adopts a frame form, wherein one end of the arch rod 1 is connected to a downwardly inclined connecting rod 5, that is, the higher end of the arch rod, the number of connecting rods 5 is consistent with the number of arch rods 1, and the inclined surface of the connecting rod 5 faces the north, and the bottom end of the connecting rod 5 is connected to a vertical support rod 6, the number of support rods 6 is consistent with the number of connecting rods 5, and the spaced connecting rods 5 and support rods 6 are also connected by a pull rod 2. In order to enable the entire greenhouse to be installed on the ground, the other lower end of the arch rod 1 and the support rod 6 are both installed on the ground. Specifically, bolt piles can be set at the bottom of the rod to connect to the ground. At this point, the main frame of the entire solar greenhouse is completed.

[0032] In this embodiment, after the main frame is built, subsequent slope covering and side wall covering are required. First, the south slope is covered with a film 7. Specifically, the film 7 is covered on top of all the arch rods 1 and can be connected to the arch rods 1 using traditional bonding methods. This is consistent with the design and installation method in the prior art, but the upper and lower ends of the film 7 are both set to be movable, and the movable films 7 are connected to film rollers 12. There are two groups of film rollers 12. The movable ends of the film 7 are connected to the winding shaft 13 of the film roller 12, and in order to realize the winding work, the film rollers 12 are rotatably connected to their respective corresponding positions.

[0033] Specifically, combined Figure 2 and Figure 3 The film reel 12 at the upper end of the film 7 is hinged to the purlin 3 through the connecting frame 14, and can rotate around the hinge point when rewinding. The film reel 12 at the lower end of the film 7 is hinged to the ground through the connecting frame 14, and in order to be able to press and fix the film 7 and limit the rewinding of the lower end, the bottom end of the arch rod 1 is provided with a film pressing member 15 perpendicular to its arrangement direction, combined with Figure 4 The film pressing member 15 is located on the outside of the film 7 and above the film rolling device 12. Whether it is the hinged connection between the film rolling device 12 and the purlin 3 or the ground, or the action of rolling up the film 7, both adopt the installation method of the existing technology. After the rolling is completed, two ventilation holes can be exposed, so that the inside and outside of the greenhouse are connected for ventilation.

[0034] The main innovation of the present scheme is that the connecting rod 5 and the outer sides of the horizontal purlin 3 and the vertical purlin 4 are fixedly covered with a first insulation layer 8. The first insulation layer 8 can be fixed to the corresponding rod by rivets or the like, and the outer side of the support rod 6 is covered with a second insulation layer 9. Both the first insulation layer 8 and the second insulation layer 9 are made of PVC scraper cloth, which can improve the insulation effect and have a certain wear resistance. The upper end of the second insulation layer 9 is fixedly connected to the support rod 6, and the lower end is movably connected and can be rolled up by a winding device 10. In order to reduce the pressure of the winding device 10, the winding height should not be too high. The upper end of the first insulation layer 8 extends to be fixed on the arch rod 1, and the lower end extends to the outer side of the support rod 6 and is contacted and fixed with the second insulation layer 9. A flat iron 11 is set at the contact position of the first insulation layer 8 and the second insulation layer 9 to press the two together so that the length of the second insulation layer 9 is between 1.8m and 2.5m.

[0035] Specifically, the winding device 10 includes a roller shutter machine 101, which can be made of existing components. The bottom end of the second insulation layer 9 is fixed to the shutter rod 102, and the roller shutter machine 101 is connected to a telescopic rod 103. The upper end of the telescopic rod 103 is hinged to the support rod 6, and the hinge of the telescopic rod 103 and the support rod 6 is mainly achieved by connecting a bracket 104 to one side of the support rod 6. The bracket 104 runs through the second insulation layer 9. The upper end of the telescopic rod 103 is hinged to the bracket 104. When the roller shutter machine is started, the second insulation layer 9 is driven to be rolled up, and at the same time, the telescopic rod 103 contracts and rotates upward around the hinge point until the second insulation layer 9 at the bottom is completely rolled up, so that the vents at the rear end of the greenhouse are exposed, and the vents at the upper and front ends of the greenhouse are opened at the same time, so that air convection can be formed, which greatly improves the ventilation effect.
