[0029] The plant factory of this embodiment makes full use of the closed environment of the hydraulic tunnel 1. By setting the first cultivation structure 10 and the second cultivation structure 20, the three-dimensional planting of plants is realized, and the space utilization rate is improved. The addition of the light-supplementing structure ensures that the plants can also get sufficient light in the tunnel, and the ventilation system 30 ensures the air circulation required for plant growth. In addition, by setting the pump body 40 and the box body 50, the recycling of the nutrient solution is achieved, which not only saves resources but also improves the growth efficiency of plants. The use of the waterproof coating protects the tunnel structure from damage, and the setting of the heating device or the heat exchange device enables the plant factory to adapt to different external environments and ensures the temperature conditions for plant growth. Overall, the plant factory of this embodiment can effectively improve the actual effect of the plant factory and provide new possibilities for agricultural planting, especially in areas with limited space or harsh environmental conditions, where its application benefits are particularly significant.

[0030] like Figure 1 As shown, the plant factory of this embodiment is located within a hydraulic tunnel 1 and includes a first cultivation structure 10, a supplemental lighting structure, a second cultivation structure 20, and a ventilation system 30. The first cultivation structure 10 includes a support frame 11 and a plurality of first cultivation boxes 12 vertically spaced apart on the support frame 11. The supplemental lighting structure is disposed on the support frame 11 to provide supplemental lighting for the plurality of first cultivation boxes 12. The second cultivation structure 20 is disposed on the sidewall of the hydraulic tunnel 1. The ventilation system 30 is disposed within the hydraulic tunnel 1.

[0031] Using the technical solution of this embodiment, a plant factory is installed within a hydraulic tunnel 1. The plant factory includes a first cultivation structure 10, a supplemental lighting structure, a second cultivation structure 20, and a ventilation system 30. The first cultivation structure 10 includes a support frame 11 and multiple first cultivation boxes 12, which are vertically spaced apart on the support frame 11. The supplemental lighting structure is installed on the support frame 11 to provide supplemental lighting to the multiple first cultivation boxes 12. The second cultivation structure 20 is installed on the side wall of the hydraulic tunnel. A ventilation system is installed within the hydraulic tunnel. Through this arrangement, the support frame 11 can support the multiple first cultivation boxes 12, which can cultivate plants. The supplemental lighting structure can provide supplemental lighting to the first cultivation boxes 12 to promote the growth of the plants within the first cultivation boxes 12. The second cultivation structure 20 can also cultivate plants and is installed on the side wall of the hydraulic tunnel 1, thereby improving the utilization rate of the space within the hydraulic tunnel 1. The ventilation system 30 can promote air circulation and ensure the growth of plants. Therefore, the technical solution of this embodiment effectively solves the problem of idle hydraulic tunnels in related technologies.

[0032] Hydraulic Tunnel 1 adopts a gate-shaped cross-section. Its primary support utilizes a combination of anchor spraying, mesh, and steel arch support. Secondary support utilizes reinforced concrete lining throughout the tunnel, with thickness ranging from 0.5m to 2.5m depending on the surrounding rock conditions. The finished cross-section measures 15.00m x 17.00m (width x height). The tunnel's ambient temperature is 22.4°C (66%) in summer and 9.2°C (51%) in winter.

[0033] Hydraulic tunnel 1 includes a diversion tunnel, a sediment drainage tunnel, and a diversion tunnel. The power supply system is located within a preset range from the plant factory. The power supply system includes surrounding hydropower, wind power, photovoltaic power, or other power generation and energy storage devices. Plants grown in the plant factory include a variety of economically viable varieties, including leafy vegetables, solanaceous fruits, flowers, and mushrooms, adapted to the high humidity and temperature environment of the hydraulic tunnel.

[0034] The fill light structure is an LED lamp. A plurality of LED lamps are arranged on the support frame, and a plurality of LED lamps are arranged above each first cultivation box 12.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, the second cultivation structure 20 includes a second cultivation box 21 extending vertically, and a third cultivation box 22 extending horizontally. By providing the second cultivation box 21 extending vertically and the third cultivation box 22 extending horizontally, the utilization rate of the hydraulic tunnel's sidewalls can be improved. This design allows the plant factory to flexibly adapt to the structure of the hydraulic tunnel 1, effectively utilizing both vertical and horizontal space, and improving planting flexibility.

[0036] The second cultivation box 21 includes a plurality of boxes arranged at intervals. The third cultivation box 22 includes a plurality of boxes arranged at intervals.

[0037] The second cultivation box 21 and the third cultivation box 22 are both provided with LED fill lights.

[0038] like Figure 3 and Figure 4 As shown, in this embodiment, the second cultivation structure 20 includes a second cultivation box 21, which extends vertically. The second cultivation box 21 includes a box body 211 and a plurality of first baffles 212 spaced apart. The box body 211 is provided with a plurality of cultivation holes 2111 spaced apart vertically. The plurality of first baffles 212 are disposed above the plurality of cultivation holes 2111 in a one-to-one correspondence. The first baffles 212 shield the corresponding cultivation holes 2111. The first baffles 212 form communication openings 23 with the inner wall of the box body 211, and the communication openings 23 are spaced apart from the corresponding cultivation holes 2111 in the transverse direction. The cultivation holes 2111 allow the roots of the plants to extend into the box body 211. The plurality of first baffles 212 block the nutrient solution, preventing it from directly impacting the plant roots and causing damage to the plants.

[0039] The box body 211 is a column, which can reduce the accumulation of debris such as broken plant roots in the box body, making the box body easier to clean.

[0040] The axis of each cultivation hole 2111 extends horizontally.

[0041] The third cultivation box 22 is also provided with a plurality of cultivation holes, and the axes of the plurality of cultivation holes provided on the third cultivation box 22 also extend in the horizontal direction.

[0042] like Figure 4 As shown, in this embodiment, the second cultivation box 21 further includes a plurality of second baffles 213 spaced apart, with one second baffle 213 disposed between any two first baffles 212. Adjacent first baffles 212 and second baffles 213 are staggered in the circumferential direction of the box body 211. This arrangement allows the first baffles 212 and second baffles 213 to stop the nutrient solution, thereby increasing the flow distance of the nutrient solution and reducing its flow velocity, thereby preventing the nutrient solution from directly impacting the plant roots.

[0043] like Figure 3As shown, in this embodiment, the plant factory further includes a pump body 40 and a housing 50. Nutrient solution is provided in the housing 50. The inlet of the pump body 40 is connected to the outlet of the housing 50, and the outlet of the pump body 40 is connected to the top of the second cultivation box 21. The inlet of the housing 50 is connected to the inlet of the second cultivation box 21. The pump body 40 can deliver the nutrient solution to the second cultivation box 21 to ensure the growth of the plants. The inlet of the housing 50 is connected to the inlet of the second cultivation box 21 to ensure the circulation of the nutrient solution.

[0044] The pump body is a water pump.

[0045] The outlet of the pump body 40 is communicated with the top of each second cultivation box 21 , and the inlet of the box body 50 is communicated with the inlet of each second cultivation box 21 .

[0046] The third cultivation box is also connected to the pump body 40 and the box body 50. Nutrient solution is provided in the box body 50. The inlet of the pump body 40 is connected to the outlet of the box body 50. The outlet of the pump body 40 is connected to the top of each third cultivation box 22. The inlet of the box body 50 is connected to the inlet of each second cultivation box 21.

[0047] like Figure 1 As shown, in this embodiment, a waterproof coating is provided on the inner wall of the hydraulic tunnel 1. This prevents moisture from entering the hydraulic tunnel 1, effectively protecting the electrical equipment within the plant factory and preventing electrical safety hazards caused by water dripping onto electrical components, as well as potential risks to the first and second cultivation structures and maintenance personnel caused by ground water accumulation.

[0048] like Figure 5 As shown, in this embodiment, the support frame 11 includes a first support column 111, a second support column 112, a third support column 113, a fourth support column 114 and a plurality of mounting components 115. The first support column 111, the second support column 112, the third support column 113 and the fourth support column 114 are arranged in sequence, and the plurality of mounting components 115 are arranged on the first support column 111, the second support column 112, the third support column 113 and the fourth support column 114 at intervals in the vertical direction. Each mounting component 115 includes a first mounting rod 1151 and a second mounting rod 1152. The first mounting rod 1151 is arranged between the first support column 111 and the second support column 112, and the second mounting rod 1152 is arranged between the third support column 113 and the fourth support column 114. The first cultivation box 12 is movably arranged between the first mounting rod 1151 and the second mounting rod 1152. The first support column 111 , the second support column 112 , the third support column 113 and the fourth support column 114 can support a plurality of mounting assemblies 115 . The first mounting rod 1151 and the second mounting rod 1152 can support the first cultivation box 12 .

[0049] like Figure 5 and Figure 6 As shown, in this embodiment, the plant factory further includes a lifting structure 60, which includes a first driving member 61, a lifting frame 62, and a second driving member 63. The lifting frame 62 is movably arranged on the first support column 111 and the fourth support column 114. The first driving member 61 is connected to the lifting frame 62 to drive the lifting frame 62 to move up and down. The second driving member 63 is movably arranged on the lifting frame 62. The second driving member 63 can drive one of the multiple first cultivation boxes 12 to move to the lifting frame 62. The second driving member 63 can push the first cultivation box 12 to move to the lifting frame 62.

[0050] like Figures 5 to 7 As shown, in this embodiment, the lifting frame 62 has a lifting state and a retracted state. When the lifting frame 62 is in the lifting state, the lifting frame 62 is arranged horizontally, and when the lifting frame 62 is in the retracted state, the lifting frame 62 is arranged vertically. The above arrangement allows the lifting frame 62 to occupy less space when not in use.

[0051] A connecting groove 121 and an avoidance groove 122 connected to the connecting groove are provided on the outer surface of the first cultivation box 12. The connecting groove 121 extends along the height direction of the first cultivation box 12. The connecting groove 121 runs through the height direction of the first cultivation box 12. The avoidance groove 122 extends from the second support column 112 to the first support column 111. The avoidance groove 122 is provided at the bottom of the first cultivation box 12.

[0052] The lifting structure 60 further includes a connecting block 64 movably disposed in the connecting groove 121 . The connecting block 64 is connected to the second driving member 63 . The second driving member 63 extends in a direction from the second supporting column 112 to the first supporting column 111 .

[0053] The lifting structure 60 also includes a support plate 65 and a slide bar 66 disposed on the side of the support plate 65. The first end of the slide bar 66 is vertically movable within the slide slot 1111 of the first support column 111, and the second end of the slide bar 66 is connected to the support plate 65. When the lifting frame 62 is in the lifting state, the support plate 65 supports the lifting frame 62. The first end of the lifting frame 62 is rotatably disposed on the slide bar 66.

[0054] The support frame 11 also includes a connecting plate 116 connected to the first support column 111 and a guide block 117 provided on the connecting plate 116, the guide block 117 having a guide slope 1171. The connecting plate 116 is provided near the bottom of the first support column 111. When the lifting frame 62 moves from the lifting state to the recovery state, the lifting frame 62 abuts against the guide slope 1171, and under the guidance of the guide slope 1171, the second end of the lifting frame 62 gradually rotates toward the support frame 11 until the side of the lifting frame 62 away from the support frame 11 abuts against the side of the guide block 117 facing the support frame 11, and the lifting frame 62 is vertically arranged.

[0055] The connecting plate 116 includes a first plate and a second plate connected to the first plate. The guide block 117 is disposed on the second plate. The first plate and the second plate are arranged perpendicularly. The distance between the guide slope 1171 and the bottom of the support frame 11 gradually increases from the second support column 112 to the first support column 111.

[0056] A torsion spring is provided between the slide bar 66 and the first end of the lifting frame 62 to enable the lifting frame 62 to move smoothly from the retracted state to the lifted state.

[0057] like Figure 1 As shown, in this embodiment, the plant factory further includes a heating device. The heating device can ensure the temperature required for plant growth in the plant factory.

[0058] In other embodiments, the plant factory further includes a heat exchange device that is in communication with an external heat source, and can ensure the temperature required for plant growth in the plant factory through the heat exchange device.

[0059] The scale and form of the soilless plant factory are determined based on the spatial structural dimensions and wall conditions of the hydraulic tunnel 1. Cultivation module layouts include vertical and wall-mounted. In the vertical cultivation format, i.e., the first cultivation structure 10, the upper limit of the number of first cultivation boxes is determined by the tunnel height and the ventilation and heat dissipation requirements of the system.

[0060] Leveraging the natural advantages of the hydraulic tunnel 1, which boasts ample space, ventilation, and suitable temperature and humidity, and abandoning the conventional HVAC system used in plant factories, this embodiment utilizes air or water cooling for spatial cooling. Heat dissipated by the LED fill lights is dissipated into the large indoor space, where it is removed by wind, or by introducing fresh air or water cooling for spatial heat exchange. In winter, the system heats the plant factory using electrical heating or by drawing in waste heat from surrounding systems.

[0061] In the wall-attached cultivation method, the second and third cultivation boxes 21, 22 are fixed to the cave wall, and the plants grow horizontally. The nutrient solution in the second and third cultivation boxes 21, 22 flows in a directional manner to flush the plant roots and provide nutritional supplements for plant photosynthesis. Wall-attached planting troughs include horizontal types (i.e., the third cultivation box 22) and vertical types (i.e., the second cultivation box 21). The cross-section of the planting trough is circular, which facilitates subsequent cleaning and reduces the accumulation of plant root secretions and nutrient solution sediment in corners. The wall-attached type is suitable for tunnels with narrow space widths.

[0062] Advantages of the second cultivation box 21 and the third cultivation box 22: Compared with the first cultivation box 12, the second cultivation box 21 and the third cultivation box 22 have simpler requirements on space and terrain and fewer restrictions, especially when the foundation and wall surface are irregular and uneven or the space is narrow. Compact and simple, occupying a small area. Compared with the inconvenience caused by the integrated design of the first cultivation box 12 and the LED fill light in the first cultivation structure 10 for installation, cleaning and disassembly, the circular planting trough (i.e., the second cultivation box 21 and the third cultivation box 22) is easier to install, clean and disassemble, and the circular planting trough and the LED fill light adopt a split design, and the LED strip light or panel light is installed at a certain distance from the circular planting trough, and the LED position can be moved according to the different growth stages of the plant to adjust the fill light intensity.

[0063] Advantages of the third cultivation box 22: staggered parallel layout improves space utilization. The circular tubes of the third cultivation box 22 form a horizontal water circulation pattern, which prolongs the flow time of the nutrient solution in the tubes and further promotes plant nutrient absorption.

[0064] Advantages of the second cultivation box 21: The staggered parallel arrangement improves space utilization. The longitudinal directional flow of nutrient solution removes broken roots, root secretions, and solid nutrient solution sediment from the plant growth process, reducing the difficulty of subsequent cleaning of the planting trough.

[0065] The lower limit of the nutrient solution level in the third cultivation box 22 is not lower than the highest point of the plant root system, ensuring that the root system is completely immersed and absorbs sufficient nutrients.

[0066] Under the influence of gravity, the nutrient solution in the second cultivation box 21 flows downward through the plant roots. The nutrient solution in the housing 50 is pumped by the pump 40 to the top of the second cultivation box 21, completing the nutrient solution circulation. To reduce stress damage to the roots caused by vertical water flow and prolong the residence time of the nutrient solution in the second cultivation box 21, a first baffle 212 and a second baffle 213 are installed above the plant roots and on the opposite side of the groove wall, forming an S-shaped flow path.

[0067] The plant factory also has an outer frame structure, which has a first operating state, a second operating state, and a third operating state. When the outer frame structure is in the first operating state, the outer frame structure is a closed structure. When the outer frame structure is in the second operating state, the outer frame structure is a semi-closed structure. When the outer frame structure is in the third operating state, the outer frame structure is an open structure.

[0068] The outer frame structure includes a first arc-shaped support rod, a second arc-shaped support rod, a first film arranged between the first arc-shaped support rod and the ground, a second film arranged between the first arc-shaped support rod and the ground, and a third film arranged between the first arc-shaped support rod and the second arc-shaped support rod.

[0069] When the outer frame structure is in the first working state, the first film covers between the first arc-shaped support rod and the ground, the second film covers between the first arc-shaped support rod and the ground, and the third film covers between the first arc-shaped support rod and the second arc-shaped support rod, so as to close the space enclosed by the first arc-shaped support rod and the second arc-shaped support rod with the ground.

[0070] When the outer frame structure is in the second working state, the first film covers between the first arc-shaped support rod and the ground, the second film covers between the first arc-shaped support rod and the ground, and the third film is removed from between the first arc-shaped support rod and the second arc-shaped support rod.

[0071] When the outer frame structure is in the third working state, the first film is removed from between the first arcuate support rod and the ground, the second film is removed from between the first arcuate support rod and the ground, and the third film is removed from between the first arcuate support rod and the second arcuate support rod.

[0072] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0073] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0074] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0075] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
