Description

Technical Field

[0001] The invention relates to the technical field of solar greenhouse design, and in particular to a large-span intensive solar greenhouse. Background Art

[0002] Solar greenhouse is the abbreviation of energy-saving solar greenhouse, also known as warm shed, which is a greenhouse without heating indoors. Solar greenhouse is mainly composed of enclosure walls (rear wall and east and west gables) and shed body, among which the front roof of the shed body is the entire lighting surface of the greenhouse. The front roof is supported by a light-transmitting film with a skeleton. During the daytime lighting period, the front roof is only covered with film for lighting. When the outdoor light weakens, the film is covered with a movable insulation blanket in time to strengthen the insulation of the greenhouse. The enclosure wall absorbs solar energy to achieve heat storage and release, maintaining a certain temperature level indoors to meet the needs of vegetable crop growth.

[0003] With the launch of relevant national scientific research projects in recent years, China's facility agriculture has developed rapidly on the basis of learning from, absorbing and digesting advanced foreign technological achievements, and the facility area and facility level have been continuously improved. As the main body of my country's facility agriculture industry, the "solar greenhouse" industry has become the most profitable industry in agricultural planting in recent years. It has made historic contributions to solving the long-standing problem of vegetable off-season supply in winter in northern my country, increasing farmers' income, saving energy, and avoiding environmental pollution caused by the greenhouse effect.

[0004] Compared with multi-span greenhouses and glass greenhouses, solar greenhouses have the characteristics of low investment and energy conservation. However, they have the following disadvantages: (1) Solar greenhouses mainly use the surrounding walls to absorb solar energy to store and release heat. The thickness of the surrounding walls, especially the rear wall 1, is relatively large. The surrounding walls and the shaded part ( Figure 1 The middle area I is the shaded area) occupies a large area, and the shaded area cannot be used as a planting area. To build one mu of solar greenhouse, about 2 mu of land is needed, and the land utilization rate is low. The effective area can only reach about 50%. (2) In addition to the front roof of the shed 3 being a transparent lighting area, the rear wall 1 and the gables 2 at the east and west ends of the solar greenhouse are all opaque enclosure walls (reference Figure 2), if the operators want to understand the growth of vegetable crops in the greenhouse, they must enter the greenhouse for observation. If they conduct research and sightseeing, observation channels must be reserved indoors. In this way, whether it is operators or tourists who frequently enter the greenhouse, on the one hand, it is easy for cold wind to blow into the greenhouse and lower the indoor temperature. On the other hand, people entering and leaving the greenhouse are likely to increase the risk of pathogen transmission, thus affecting the healthy growth of crops. (3) After the greenhouse crops are harvested, fruits and vegetables need to be manually transported out of the greenhouse for sorting, packaging or processing and storage. On the one hand, the transportation operation is inconvenient, consumes manpower and material resources, and has high transportation costs. On the other hand, it is necessary to build an independent packaging and processing workshop in the greenhouse park to carry out sorting, packaging or processing operations. Under the influence of limited land resources and rising labor costs, it is impossible to adapt to the needs of modern production. Summary of the invention

[0009] As a preferred technical solution, a transport track passing through the functional area is provided between the entrance ramp channel and the exit ramp channel.

[0010] As a preferred technical solution, the transport track extends in a winding manner from the entrance and exit of the entrance channel partition to the greenhouse planting area.

[0015] As a preferred technical solution, the top of the inner base wall is covered with a cement layer and a decorative layer in sequence from bottom to top.

[0016] Due to the adoption of the above technical solution, the present invention has at least the following beneficial effects:

[0017] (1) The rear wall is composed of an outer retaining wall and an inner base wall, the wall height of the inner base wall is less than the wall height of the outer retaining wall, and a functional area is formed between the upper part of the inner base wall and the rear roof of the shed body; an entrance ramp passage leading to the functional area is arranged on the inner side of the gable at one end, and an exit ramp passage leading to the functional area is arranged on the inner side of the gable at the other end; a rear partition extending upward to the top of the shed body is arranged along the inner side wall of the inner base wall, an entrance channel partition extending upward to the top of the shed body is arranged on the inner side of the entrance ramp passage, and an exit channel partition extending upward to the top of the shed body is arranged on the inner side of the exit ramp passage, and the rear partition, the entrance channel partition, the exit channel partition and the front roof of the shed body are enclosed to form a greenhouse planting area. Area, the functional area is isolated from the greenhouse planting area; through the above structural design, the shade area of ​​the traditional solar greenhouse is cleverly transformed into a functional area. On the one hand, this part of the functional area forms a sandwich insulation space between the outer insulation room and the greenhouse planting area. The insulation space can enhance the insulation effect of the greenhouse and is more conducive to maintaining the indoor temperature level; on the other hand, this part of the functional area can be used as a sorting, packaging and processing area for fruits and vegetables. The fruits and vegetables harvested from the planting area can be quickly transported to the functional area for sorting and packaging. The transportation operation is very convenient, and there is no need to build an independent packaging and processing workshop in the greenhouse park, so that land resources can be fully saved and the utilization rate of the greenhouse space is maximized.

[0018] (2) After the shaded area of ​​the traditional solar greenhouse is transformed into a functional area, since the functional area is isolated from the greenhouse planting area, the growth of crops in the greenhouse planting area can be directly observed from the transparent observation window on the rear partition near the functional area. The workers do not need to enter the greenhouse planting area, which not only avoids the problem of frequent entry and exit causing cold wind to blow into the greenhouse planting area and thus lower the indoor temperature, but also avoids the problem of frequent entry and exit increasing the risk of pathogen transmission, which is conducive to the healthy growth of crops. At the same time, by setting up functional areas, an observation channel passing through the functional area is set from the entrance ramp to the exit ramp, which can completely change the problem that the traditional solar greenhouse is not suitable for external research and study tourism, and research and study tourism will not affect the healthy growth of crops in the greenhouse planting area.

[0019] (3) A transport track passing through the functional area is provided between the entrance ramp channel and the exit ramp channel, and the transport track extends from the entrance and exit separated by the entrance channel to the greenhouse planting area. In this way, after the fruits and vegetables in the greenhouse planting area are harvested, they can be automatically transported to the functional area by a track trolley running along the transport track for corresponding sorting and packaging operations, which makes the transportation of fruits and vegetables convenient, improves the degree of automation, and adapts to the needs of modern production.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present invention are described only by way of illustration. Needless to say, those of ordinary skill in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0030] like Figure 3 As shown, the large-span intensive solar greenhouse includes a rear wall 1, gables 2 at the east and west ends, and a shed body 3. The rear wall, gables 2 at both ends, and the shed body 3 together form an outer insulation room body.

[0031] refer to Figure 5 The rear wall 1 is composed of an outer retaining wall 17 and an inner base wall 18. The wall height H1 of the inner base wall 18 is less than the wall height H2 of the outer retaining wall 17. A functional area 4 is formed between the upper part of the inner base wall 18 and the rear roof of the shed body 3. The projection area of ​​the functional area 4 is roughly equivalent to the projection area of ​​the shaded part of a traditional solar greenhouse of the same size. The functional space 4 can realize sandwich heat storage and serve as sorting, packaging, processing area or observation channel and other multiple functions, which will be explained in detail below.

[0032] refer to Figures 3 to 5In this embodiment, an entrance ramp passage 5 leading to the functional area 4 is arranged on the inner side of the east end gable 2, and an exit ramp passage 6 leading to the functional area 4 is arranged on the inner side of the west end gable 2; a rear partition 7 extending upward to the top of the shed body is arranged along the inner wall of the inner base wall 18, an entrance passage partition 8 extending upward to the top of the shed body is arranged on the inner side of the entrance ramp passage 5, and an exit passage partition 9 extending upward to the top of the shed body is arranged on the inner side of the exit ramp passage 6; the rear partition 7, the entrance passage partition 8, the exit passage partition 9 and the front roof of the shed body 3 enclose a greenhouse planting area 10, and the functional area 4 is isolated from the greenhouse planting area 10; an entrance and exit 11 for entering and exiting the greenhouse planting area 10 is arranged on the entrance passage partition 8. Through the above structural design, the shaded area of ​​the traditional solar greenhouse is cleverly transformed into a functional area. On the one hand, this functional area forms a sandwich-type insulating space between the outer insulation room and the greenhouse planting area 10. The insulating space can enhance the insulation effect of the greenhouse and is more conducive to maintaining the indoor temperature level; on the other hand, this functional area can be used as a sorting, packaging and processing area for fruits and vegetables. The fruits and vegetables harvested from the planting area can be quickly transported to this functional area for sorting and packaging. The transportation operation is very convenient, and there is no need to build an independent packaging and processing workshop in the greenhouse park, so that land resources can be fully saved and the utilization rate of the greenhouse space is maximized.

[0033] refer to Figure 3 and Figure 7 An observation passage 12 passing through the functional area 4 is provided between the entrance ramp passage 5 and the exit ramp passage 6, and a transparent observation window 13 is provided on the rear partition 7, so that the operator can directly observe the crop growth in the greenhouse planting area 10 from the transparent observation window 13 on the rear partition 7 close to the functional area 4. Since the functional area 4 is isolated from the greenhouse planting area 10, the operator does not need to enter the greenhouse planting area 10, which not only avoids the problem that frequent entry and exit easily causes cold wind to blow into the greenhouse planting area and thus lower the indoor temperature, but also avoids the problem that frequent entry and exit easily increases the risk of pathogen transmission, which is conducive to the healthy growth of crops. At the same time, this can completely change the problem that traditional solar greenhouses are not suitable for external research and study tours. If there is a need for research and study, the researchers and tourists enter the functional area without affecting the healthy growth of crops in the greenhouse planting area.

[0034] Refer to Figure 3A transport track 14 passing through the functional area 4 is provided between the entrance ramp channel 5 and the exit ramp channel 6. The transport track 14 extends from the entrance and exit 11 of the entrance channel partition 8 to the greenhouse planting area 10. In this way, after the fruits and vegetables in the greenhouse planting area 10 are harvested, they can be automatically transported to the functional area 4 by the track trolley running along the transport track 14 for corresponding sorting and packaging operations. The transportation of fruits and vegetables is very convenient, which is convenient for improving the degree of automation and adapting to the needs of modern production.

[0035] In this embodiment, an inlet buffer zone 15 is provided at the inlet side of the inlet ramp channel 5, and an outlet buffer zone 16 is provided at the outlet side of the outlet ramp channel 6. By providing buffer zones at the inlet and outlet of the ramp channel, air rushing space is formed to prevent cold air from entering the outer insulation chamber as much as possible.

[0036] refer to Figure 5 and Figure 6 In this embodiment, a concrete cushion layer 19 is provided at the bottom of the inner base wall 18, an inner brick wall 20 is provided on the inner side of the inner base wall 18, an outer brick wall 21 is provided on the outer side of the inner base wall 18, a plurality of support columns 22 are provided on the rear partition 7, a crossbeam 23 is provided between adjacent support columns 22, the lower end of the support column 22 is embedded in the inner brick wall 20, and the lower end of the rear frame of the shed body 3 is embedded in the outer brick wall 21. A plurality of tie bars 24 are provided at the top of the inner base wall 18, one end of the tie bar 24 is connected to the support column 22 on the rear partition 7, and the other end of the tie bar 24 is connected to the rear frame of the shed body 3. In this way, the shed body frame, the rear partition and the rear wall are constructed into an organic whole, which greatly improves the overall stability of the greenhouse structure and provides a solid foundation for the use of the functional area. The top of the inner base wall 18 is covered with a cement layer 25 and a decorative layer 26 from bottom to top, so as to provide a clean ground environment for the functional space. Of course, the above structure can also be modified, which does not constitute a limitation on the protection scope of the present invention.

[0037] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
