Description

Technical Field

[0001] The present invention relates to the technical field of greenhouses, and in particular to a spliced ​​PC board and a modular greenhouse covering layer. Background Art

[0002] Greenhouses, as a vital agricultural infrastructure, artificially create a suitable growing environment for crops. They can be used to cultivate warm-loving crops during cooler seasons, increasing greenhouse crop yields. Greenhouses have played a significant role in increasing agricultural production and income, and improving the growing environment for crops. As of 2022, greenhouses accounted for 25.3% of the total agricultural output value, utilizing less than 3% of arable land. Their economic benefits are over 20 times those of field crops.

[0003] Greenhouses are mainly divided into three types: multi-span greenhouses, plastic greenhouses, and solar greenhouses. Multi-span greenhouses are mostly made of glass, which is expensive and requires heating systems, causing certain environmental pollution and energy consumption. Plastic greenhouses are less effective, and the plastic film is easily damaged and has a short lifespan. Frequent replacement causes white plastic pollution. Solar greenhouses have large walls and are difficult to move. The investment cost of using brick walls as the main walls is high, and earth walls are not suitable for the humid climate of southern China.

[0004] Current greenhouse design and construction methods vary widely, lacking strong standardization. Construction consumes high time and labor costs, hindering intensive resource utilization. Therefore, modular greenhouse design can help standardize greenhouse building components, improve overall quality control, reduce the difficulty of greenhouse construction, and promote the development of a consumer market focused on agricultural experience. Currently, research on modular greenhouse structures primarily focuses on large-scale greenhouses, which have high investment costs and long payback periods. Summary of the Invention

[0005] The purpose of the present invention is to provide a spliced ​​PC board and a modular greenhouse covering layer.

[0040] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operating processes, but the protection scope of the present invention is not limited to the following embodiments.

[0041] Example 1

[0042] A spliced ​​PC board includes an upper PC board 1 and a lower PC board 2 spliced ​​together. Figure 1 As shown, a trapezoidal slider is provided at the bottom of the upper PC board 1 along its length, and a trapezoidal groove is provided at the top of the lower PC board 2 along its length. When splicing, the trapezoidal slider of the upper PC board 1 slides into the trapezoidal groove of the lower PC board 2.

[0043] Example 2

[0044] A spliced ​​PC board includes an upper PC board 1 and a lower PC board 2 spliced ​​together. Figure 2 As shown, a trapezoidal groove is provided at the bottom of the upper PC board 1 along its length, and a trapezoidal slider is provided at the top of the lower PC board 2 along its length. When splicing, the trapezoidal slider of the lower PC board 2 slides into the trapezoidal groove of the upper PC board 1.

[0045] Example 3

[0046] A spliced ​​PC board comprises an upper PC board 1 and a lower PC board 2, which are spliced ​​together. The upper PC board 1 has a trapezoidal slider along its bottom length, which is smaller at the top and larger at the bottom. The lower PC board 2 has a trapezoidal groove along its top length, which matches the slider. During splicing, the trapezoidal slider of the upper PC board 1 slides into the trapezoidal groove of the lower PC board 2.

[0047] Example 4

[0048] A spliced ​​PC board comprises an upper PC board 1 and a lower PC board 2, which are spliced ​​together. The upper PC board 1 has a trapezoidal groove along its bottom along its length, with the groove being larger at the top and smaller at the bottom. The lower PC board 2 has a trapezoidal slider along its top along its length that matches the groove. During splicing, the trapezoidal slider of the lower PC board 2 slides into the trapezoidal groove of the upper PC board 1.

[0049] Example 5

[0050] A spliced ​​PC board, such as Figures 3-4 As shown, a corresponding slot is provided on the edge of the upper PC board 2, into which a metal frame 4 is inserted. A side PC board 3 is placed on the left or right side of the PC board 1 or the lower PC board 2, sleeved outside the metal frame 4. A slot is provided on the edge of the side PC board 3, and a PC bar 5 is provided on the upper or lower PC board 1, connecting the side PC board 3 to the upper or lower PC board 2.

[0051] Example 6

[0052] A spliced ​​PC board, with groove sliders connecting the upper and lower PC boards, similar to the slide rail sliders. Figures 5-6 As shown in the figure, the head of the PC board has a raised trapezoidal "slider" and the tail has a trapezoidal groove "slide track". By sliding the slider of one PC board into the slide track of another PC board, the two PC boards can be connected.

[0053] The connection between the PC boards and the metal frame is similar—slots are designed along the edges of the two PC boards, allowing the metal frame to be pushed into the slots. The PC bars are then inserted into the hollow grooves in the center of the PC boards, securing the metal frame while also securing the left and right PC boards. In this embodiment, the metal frame is made of galvanized square steel, which offers high strength, long life, and excellent corrosion resistance, making it less susceptible to rust from factors like rain.

[0054] Example 7

[0055] A modular greenhouse covering, such as Figure 7 As shown, it includes a wall 6 and a side wall 7 and a ceiling 8 connected to the wall 6 and composed of spliced ​​PC boards. Ventilation holes 9 are provided on the side wall 7 or the ceiling 8.

[0056] PC boards are suitable for greenhouse coverings due to their energy efficiency, flexibility, and excellent impact resistance, light transmittance, and temperature adaptability. This embodiment utilizes a modular assembly solution, leveraging the ease of transport and installation of PC boards. This allows for easy assembly and disassembly, enabling reuse and saving costs and energy.

[0057] like Figure 8 As shown, the vent 9 includes a PC opening plate 91, a PC square plate 92, a rope 93, an electric push rod 94, a spring 95, and a pulley 96. The PC square plate 92 is rotatably mounted at the opening of the PC opening plate 91. The electric push rod 94 is mounted on the PC opening plate 91. The pulley 96 is mounted on the fixed end of the electric push rod 94 and is wrapped with a rope 93. One end of the rope 93 is connected to the telescopic end of the electric push rod 94, and the other end is connected to the center of the upper end of the PC square plate 92. The lower end of the PC square plate 92 is connected to the PC opening plate 91 via a spring 95. When one end of the electric push rod 94 is extended, it pulls the rope 93 to rotate the pulley 96, thereby pulling the other end of the rope 93 to rotate the PC square plate 92, that is, the vent 9 opens.

[0058] In this embodiment, the PC square plate 92 can be rotated by the electric push rod 94 to stretch the spring 95 to achieve the opening function at different angles. When the vent needs to be closed, the electric push rod 94 retracts and the stretched spring 95 returns to its original position, driving the vent 9 to close.

[0059] Therefore, based on different regions and planted plants, different numbers of PC boards with vents can be installed in different locations, and different vent opening periods can be selected.

[0060] Compared to glass greenhouses that require heating, this solar greenhouse utilizes modular PC panels. The panels have low thermal conductivity, reducing heating and cooling costs, improving energy efficiency, and avoiding the energy consumption and excessive carbon dioxide emissions associated with heating, thus contributing to carbon peak and carbon neutrality. It is estimated that 800,000 hectares of solar greenhouses could save over 780 million tons of coal annually compared to multi-span glass greenhouses, accounting for approximately one-sixth of national coal consumption, and reduce carbon dioxide emissions by over 1.5 billion tons, significantly reducing environmental pollution.

[0061] The PC board vents of the present invention adopt a natural ventilation mode, which significantly saves energy and reduces carbon dioxide emissions compared to mechanical ventilation.
