Description

Technical Field

[0001] This utility model relates to the field of agricultural facility technology, specifically a drainage system for seedling greenhouses. Background Technology

[0002] In modern agricultural facilities, seedling greenhouses serve as important crop cultivation sites, and their internal environment is crucial to crop growth. However, in practical applications, seedling greenhouses often face the problem of poor drainage, especially during seasons with frequent rainfall or excessive irrigation. Water accumulates inside the greenhouse and is difficult to drain quickly, leading to excessively high soil moisture, which affects the respiration and normal growth of crop roots, and may even cause the breeding of pests and diseases.

[0003] Traditional drainage systems in seedling greenhouses often suffer from problems such as unreasonable design, inappropriate material selection, and non-standard construction, resulting in low drainage efficiency and failing to meet the high-efficiency and precise production needs of modern agriculture. Specifically, traditional drainage systems may lack a multi-layered drainage structure, failing to effectively collect and guide accumulated water; unreasonable ditch layout leads to poor drainage or water stagnation; drainage pipes with too small a diameter or of poor quality affect drainage speed and effectiveness; and the lack of regular maintenance and cleaning exacerbates blockages and failures in the drainage system.

[0004] Furthermore, with the increasing scale and intensification of agricultural production, the requirements for drainage systems in seedling greenhouses are becoming increasingly stringent. These systems not only need to be highly efficient and stable, but also need to be economical, environmentally friendly, and sustainable. Therefore, developing a new and efficient drainage system for seedling greenhouses has become an urgent problem to be solved in the field of agricultural facilities.

[0005] In summary, this patent was proposed against this backdrop. Through in-depth research and analysis of the problems and shortcomings of traditional seedling greenhouse drainage systems, and in combination with the actual needs and development trends of modern agricultural production, this patent aims to design a new type of seedling greenhouse drainage system that is structurally sound, made of high-quality materials, constructed according to standards, and easy to maintain, in order to improve drainage efficiency, protect the crop growth environment, and promote the sustainable development of agricultural production. Utility Model Content

[0006] To address the problems of the prior art, this utility model provides a drainage system for seedling greenhouses.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a drainage system for a seedling greenhouse, comprising:

[0008] The main body of the greenhouse serves as the seedling cultivation space;

[0009] Brick walls are set around the main body of the greenhouse to enclose and support it.

[0010] Geotextile is laid at the bottom of the interior of the main body of the greenhouse as a waterproof layer;

[0011] Large crushed stones are laid on top of geotextile for rapid drainage;

[0012] Small gravel is laid on top of large gravel to further improve drainage and provide support;

[0013] Ditches are distributed crisscrossingly inside the main body of the greenhouse, serving as water collection channels;

[0014] Drainage pipes connect drainage ditches and canals to discharge accumulated water inside the greenhouse to the outside.

[0015] The drainage ditch, located on the outside of the brick wall, receives drainage from inside the greenhouse and directs it to a safe area away from the greenhouse.

[0016] In this embodiment, firstly, a geotextile laid at the bottom of the main body of the greenhouse serves as a waterproof layer, effectively preventing soil moisture from directly penetrating to the bottom structure and maintaining a dry and clean environment inside the greenhouse. Large gravel is laid on top of the geotextile, forming the first drainage layer. The larger gaps between the large gravel particles allow for rapid collection and guidance of excess water from the soil or irrigation, achieving initial rapid drainage through their excellent permeability. Small gravel is laid on top of the large gravel, further refining the drainage effect. The small gravel not only increases the surface area of ​​the drainage layer and improves water infiltration efficiency but also provides additional support, preventing the upper soil or crop roots from sinking and maintaining the stability of the soil structure. The crisscrossing ditches inside the greenhouse serve as water collection channels, effectively collecting excess water from the soil and gravel layer. The design of these ditches ensures that water can be guided evenly and quickly to designated locations. Drainage pipes connect the drainage ditches to the ditches inside the greenhouse, using gravity to drain accumulated water from inside the greenhouse into drainage ditches located on the outside of the brick walls. The drainage ditch is responsible for guiding the collected water to a safe area away from the greenhouse, avoiding potential damage to the greenhouse foundation and the surrounding environment caused by water accumulation.

[0017] In one specific implementation, multiple columns are equidistantly distributed along the length of the main body of the greenhouse at its center to support the main body of the greenhouse.

[0018] In one specific implementation, the size difference between large and small gravel is designed to create a multi-layered drainage structure to improve drainage efficiency.

[0019] In one specific implementation, the design of the ditch allows water inside the shed to quickly collect and flow to the drainage pipe, thereby ensuring a dry environment inside the shed.

[0020] The design of the drainage ditch takes into account the drainage volume, topographical conditions and the surrounding environment to ensure smooth drainage and to avoid adverse effects on the surrounding environment.

[0021] In one specific embodiment, the particle size of the large-particle crushed stone is set to 20-40 mm, and the laying thickness is set to 200 mm; the particle size of the small-particle crushed stone is set to 10-20 mm, and the laying thickness is set to 50 mm.

[0022] In one specific implementation, the main body of the greenhouse is set to be 43,800 mm long and 16,000 mm wide;

[0023] The ditch width is set at 400 mm, and the diameter of the drainage pipe is set at 110 mm;

[0024] In one specific implementation, the distances between the ditches distributed along the length of the main body of the greenhouse are set sequentially to 1700 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, and 1700 mm.

[0025] In one specific implementation, the distances between the ditches distributed sequentially along the width direction inside the main body of the greenhouse are set to 2600 mm, 2200 mm, 4800 mm, 2600 mm, and 2600 mm, respectively.

[0026] The beneficial effects of this utility model are as follows:

[0027] 1. This utility model, through the adoption of a multi-layered drainage structure combining large and small gravel, and a rationally laid-out ditch network, enables the system to quickly collect and guide accumulated water within the greenhouse, significantly improving drainage efficiency. This helps reduce the adverse effects of waterlogging on crop growth, ensuring a stable and suitable growing environment for crops;

[0028] 2. Laying small-particle gravel not only improves drainage but also provides additional support, effectively preventing the upper soil or crop roots from sinking due to waterlogging. This helps maintain soil structure stability and provides a good root environment for crop growth;

[0029] 3. An efficient drainage system can promptly remove accumulated water from the greenhouse, reducing humidity and minimizing the breeding of pests and diseases. Simultaneously, a dry greenhouse environment is beneficial for crop respiration and photosynthesis, improving crop growth rate and quality; waterlogging is one of the main factors causing damage to greenhouse structures. This patented drainage system effectively removes accumulated water, reducing its erosive effect on the greenhouse foundation, thereby extending the greenhouse's lifespan and reducing maintenance costs.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figure 1 , Figure 2 and Figure 3 The drainage system for a seedling greenhouse shown includes: a greenhouse body 1, serving as the seedling space; a brick wall 6, located around the greenhouse body 1, used to enclose and support the greenhouse; a geotextile 5, laid at the bottom of the interior of the greenhouse body 1, serving as a waterproof layer; large-particle gravel 3, laid on top of the geotextile 5, for rapid drainage; small-particle gravel 2, laid on top of the large-particle gravel 3, further refining the drainage effect and providing support; ditches 8, distributed crisscrossingly inside the greenhouse body 1, serving as water collection channels; a drainage pipe 4, connecting the drainage ditch 7 and the ditch 8, enabling the discharge of water accumulated inside the greenhouse to the outside; and the drainage ditch 7, located outside the brick wall 6, receiving drainage from inside the greenhouse and guiding it to a safe area away from the greenhouse.

[0039] Multiple pillars 9 are evenly distributed along the length of the main body of the greenhouse 1 at its center to support the main body. The size difference between large and small gravel 3 and 2 is designed to create a multi-layered drainage structure to improve drainage efficiency. The design of the ditch 8 allows water inside the greenhouse to quickly collect and flow to the drainage pipe 4, thus ensuring a dry environment inside the greenhouse. The design of the drainage ditch 7 takes into account drainage volume, terrain conditions, and the surrounding environment to ensure smooth drainage without adversely affecting the surrounding environment.

[0040] First, geotextile 5 is laid at the bottom of the interior of the main greenhouse 1 as a waterproof layer. Geotextile 5 has good waterproof performance and can effectively prevent water in the soil from directly penetrating into the bottom structure, keeping the interior environment of the greenhouse dry and clean.

[0041] On top of the geotextile 5, large-particle crushed stone 3 and small-particle crushed stone 2 are laid in sequence to form a multi-layered drainage structure. The large gaps between the large-particle crushed stones 3 can quickly collect and guide excess water from the soil or irrigation, achieving initial rapid drainage. The small-particle crushed stone 2 further refines the drainage effect, increases the surface area of ​​the drainage layer, improves water infiltration efficiency, and provides additional support to prevent the upper soil or crop roots from sinking.

[0042] The crisscrossing ditches 8 inside the main body of the greenhouse serve as water collection channels. Their design allows water inside the greenhouse to quickly gather and flow to the nearest ditch. The crisscrossing layout of the ditches 8 ensures that water can be guided evenly and quickly to the designated location, reducing the time water remains in the greenhouse.

[0043] Drainage pipe 4 connects drainage ditch 7 and ditch 8, using gravity to drain accumulated water inside the shed into drainage ditch 7 located outside the brick wall 6. The design of drainage pipe 4 takes into account factors such as drainage volume, flow rate, and pressure to ensure smooth and unobstructed drainage.

[0044] Drainage ditch 7 is located outside the brick wall 6, receiving drainage from inside the greenhouse and guiding it to a safe area away from the greenhouse. The design of drainage ditch 7 fully considers drainage volume, terrain conditions, and the surrounding environment. Through reasonable slope design, reinforcement measures, and seepage prevention treatment, it ensures smooth drainage and does not have an adverse impact on the surrounding environment.

[0045] Multiple columns 9 are evenly distributed along the length of the main body 1 at the center of the greenhouse. These columns not only support the structure of the main body 1, but also enhance the stability of the entire drainage system through their stable support, preventing structural deformation or damage caused by water accumulation or external forces.

[0046] Example: Figure 4 , Figure 5 and Figure 6As shown, the particle size of the large-particle crushed stone 3 is set to 20-40 mm, and the laying thickness is set to 200 mm; the particle size of the small-particle crushed stone 2 is set to 10-20 mm, and the laying thickness is set to 50 mm. The main body of the greenhouse 1 is set to be 43,800 mm long and 16,000 mm wide; the width of the ditch 8 is set to 400 mm, and the diameter of the drainage pipe 4 is set to 110 mm; the distances between the ditches 8 distributed along the length direction inside the main body of the greenhouse 1 are set to 1700 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 1700 mm; the distances between the ditches 8 distributed along the width direction inside the main body of the greenhouse 1 are set to 2600 mm, 2200 mm, 4800 mm, 2600 mm, 2600 mm.

[0047] Material specifications:

[0048] Large-particle crushed stone 3: Particle size set at 20-40 mm, laying thickness set at 200 mm. This size of large-particle crushed stone can quickly collect and guide excess water in the soil, achieving initial rapid drainage.

[0049] Small crushed stone 2: The particle size is set to 10-20 mm, and the laying thickness is set to 50 mm. Small crushed stone further refines the drainage effect, increases the surface area of ​​the drainage layer, improves water infiltration efficiency, and provides additional support.

[0050] Greenhouse main body dimensions:

[0051] Greenhouse Main Body 1: The length is set at 43,800 mm and the width at 16,000 mm. This size design accommodates the needs of large-scale seedling cultivation while ensuring that the drainage system can cover the entire greenhouse area.

[0052] Ditch and drainage pipe design:

[0053] Ditch 8: With a width of 400 mm, it serves as a water collection channel, quickly gathering accumulated water inside the greenhouse. The ditches are distributed crisscrossingly along the interior of the greenhouse, forming an efficient drainage network.

[0054] Drainage pipe 4: with a diameter of 110 mm, connects drainage ditch 7 and ditch 8 to ensure that water accumulated inside the shed can be smoothly drained into the external drainage ditch.

[0055] Ditch layout:

[0056] Along the length of the main greenhouse 1, the distances between the ditches 8 are successively 1700 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, 3600 mm, and 1700 mm. This non-uniform layout takes into account the drainage needs of different areas, ensuring maximum drainage efficiency.

[0057] Along the width of the main greenhouse 1, the distances between the ditches 8 are 2600 mm, 2200 mm, 4800 mm, 2600 mm, and 2600 mm, respectively. This layout adapts to the terrain variations and drainage requirements along the width of the greenhouse.

[0058] This embodiment achieves rapid collection and drainage of water inside the seedling greenhouse through precise material selection and structural design. The multi-layered drainage structure improves drainage efficiency, ensuring a dry and stable environment inside the greenhouse. At the same time, the reasonable ditch layout and drainage pipe design ensure smooth and unobstructed drainage, avoiding potential damage to the greenhouse structure and surrounding environment caused by water accumulation.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
