The inspection port cover 12 is provided with an air vent 13 to maintain the pressure balance in the bottom water tank 2 .

[0020] Working principle: Nutrient solution is stored in the bottom water tank 2. It is powered by the water pump 51, flows through the irrigation pipe 52, and is sprayed into the planting pipe 3 through the nozzle 53 to water the roots of the vegetables. Then, it flows back to the bottom water tank 2 through the drainage member 9. When the nutrient solution in the bottom water tank 2 is consumed to a low water level, the pressure sensor 63 can detect the insufficient water level and transmit the signal to the control system. The control system replenishes the nutrient solution into the bottom water tank 2 in a quantitative manner through the fertilizer pipe 61. The end of the fertilizer pipe 61 is equipped with a float valve 62. When the nutrient solution is replenished to the highest water level, the float valve 62 will also prevent the nutrient solution from overflowing. To solve the problem of limited space: Use vertical planting equipment and minimize the spacing. PVC110 pipes are used for vertical planting. The advantage of this equipment is that the planting holes of the PVC110 pipes can be made into single-sided or double-sided. The single-sided one is used for the wall position, and the double-sided one is used for the middle position. In addition, the length of this equipment can be made into any length, so that both horizontal and vertical space can be fully utilized. The fill light is designed as a movable integral light frame 71. The fill light frame 71 has double-sided lighting. The fill light is set between two rows of equipment and can be moved parallel to the movable track. In this way, it can move left and right while lighting, freeing up space for operating equipment, thereby making full use of the space. Regarding lighting issues: A movable fill light stand 71 is designed. The fill light adopts a full-spectrum fill light with the following requirements: luminous efficiency of not less than 2.1 μmol / J, AC 220V / 50Hz, lifespan of not less than 30,000 hours, IP65 protection; average PPFD of the cultivation surface of not less than 220 μmol / m2 / s; a light stand movable track 8 is fixed on the planting tube 3 frame 1, equipped with synchronous wheels and synchronous belts, so that the fill light stand 71 can move on the movable track, and the position of the light stand 71 can be manually adjusted; Nutrient solution stability issues: Installing a wave-breaking plate 10: Due to the instability of the hull, it is necessary to prevent the nutrient solution in the nutrient solution tank from leaking due to the hull's swaying. Specifically, a wave-breaking plate 10 is installed inside the tank. As shown in the figure, the wave-breaking plate 10 consists of baffles running along the length of the tank. A channel is left at the bottom of the baffle for the nutrient solution to pass through. When the hull sways, the upper wave-breaking plate 10 reduces the distance the nutrient solution sways from side to side, thereby reducing the impact and amplitude of the swaying. The tank is made of stainless steel to ensure its durability. The stainless steel tank requires the following features: an opening for the fertilizer pipe 61, an opening for the irrigation pipe 52, a vent 13, a pressure sensor 63, a return port, and an inspection port. All these ports must be sealed to prevent leakage. Specifically, stainless steel threaded fittings are welded directly to the bottom tank 2 for the fertilizer pipe 61, the irrigation pipe 52, the vent 13, and the pressure sensor 63. These are then connected to the inside and outside of the tank 2 using the corresponding pipes and fittings. The inspection port is fixed with traditional bolts and pressed with silicone pads to prevent water leakage. The return port is the pipe for the nutrient solution to return after watering the PVC110 planting pipe. Here, a silicone protective coil is inserted into the PVC pipe to connect it. The protective coil can effectively fit the return port of the water tank and the return pipe of the planting pipe, thus effectively preventing water leakage. Regarding node resilience issues: Because hull sway generates horizontal loads, the connection nodes of various equipment, pipes, and accessories need to be configured as flexible connections. Otherwise, due to the different masses and inertia of each component, the displacement differences can easily cause breakage. The connection nodes of the irrigation pipe 52 and the fertilizer pipe 61 to the bottom water tank 2 are connected using flexible connections. The drainage fitting 9 between the planting pipe 3 and the bottom water tank 2 is connected using a silicone rubber ring, which is an excellent connection method with good sealing and flexible connection.

[0021] Regarding the control of nutrient solution amount: Since the water tank is sealed, the liquid level of the nutrient solution in the water tank cannot be seen, so a pressure sensor 63 is designed and installed. The pressure sensor 63 can measure the water pressure according to the depth of the liquid level, thereby knowing the liquid level height and realizing the control of the nutrient solution.
