the main water pipe 400 is connected with a water outlet of a previous planting pot and a water inlet of a next planting pot. The water outlet of the planting pot at the tail end is connected with a backflow water pipe 401. All the overflow ports 341 of the planting pot 300 are connected with the return water pipe 401.
The invention also comprises a control board 500, wherein the control board 500 is connected with a water pump 510, and the water pump 510 is arranged on a water pipe between the water tank 100 and the planting chain 200; the control panel 500 is connected to the first water level sensor 520.
The control panel 500 may be an embedded circuit board, and the control panel 500 is generally disposed beside the water tank, and the first water level sensor 520 is connected to the control panel 500 through a cable installed on the return water pipe 401.
The movable water plate 350 is provided with a chute 351, the chute 351 penetrates through the side wall of the planting pot 300, a slide bar 352 is arranged in the chute 351, one end of the slide bar 352 is provided with a nutrient frame 353, and the other end of the slide bar 352 is provided with a handle 354.
The main water pipe 400 comprises a pipe body 410, wherein a plurality of petals 420 are uniformly arranged on two sides of the pipe body 410, and the petals 420 have the same inclination direction; the valve 420 includes a cavity 421, and an orientation block 422 is disposed in the cavity 421.
The water storage portion 310 is further provided with a hollow column 302.
The separation net 360 comprises a net body 361, and absorbent cotton 362 is arranged on the net body 361.
The water tank 100 is provided with a second water level sensor 110, the water tank 100 is also connected with a fire-fighting pressure water supply pipe, and an emergency valve 120 is arranged between the water tank 100 and the fire-fighting pressure water supply pipe; the second water level sensor 110 and the emergency valve 120 are connected with the control panel 500.
Working principle: as shown, the first water level sensor 520 includes a high water level contact and a low water level contact. The water level information of all the plant pots 300 is transmitted to the control board 500, and when the control board 500 judges that a plurality of plant pots 300 reach a low water level, an irrigation program is started. The control board 500 controls the water pump 510 to draw water from the water tank 100 and convey the water to the planting chain 200 through a pipeline.
As shown, when the water flow direction in the main water pipe 400 is left to right, the water flow is hardly disturbed. When the direction of water flow is from right to left, as shown in fig. 10, a portion of water flows through the petals 420, and after passing through the tube formed by the cavities 421 and the directional blocks 422, the water flows in the opposite direction to the original direction, i.e., from left to right, thereby obstructing the flow of the water. Since the tube 410 is provided with a plurality of flaps 420, the water flow from right to left is hardly circulated. This is the principle that the main water pipe 400 is one-way circulated by a fixed structure. The same applies to the return water pipe 401.
Under the action of the main water pipe 400, water flows unidirectionally from one planting pot to the next planting pot in turn. As shown in fig. 9, in the single planting pot 300, the space formed by the partition 301 and the pot wall is filled with water at the water inlet 330, when the water overflows the partition 301 to strike the water flap 350 and wash the nutrient rack 353, the water is accumulated in the water storage part 310 with nutrients. When the water level in the water storage portion 310 is higher than the water outlet 340, the water flows through the main water pipe 400 toward the next planting pot until the water in the planting pot at the end of the planting chain 200 flows back to the water tank 100 through the return water pipe 401. The control board 500 decides an irrigation stop time according to signals of the high water level contacts of the first water level sensor 520 of each plant pot 300.
The height of the nutrient frame 353 is not lower than the water outlet 340, and the water outlet 340 determines the maximum water level in the reservoir 310 in general. Thus, after irrigation is stopped, as the absorbent cotton 362 diffuses moisture into the planting portion 320, the liquid level in the water storage portion 310 drops, the nutrient rack no longer contacts water, and the nutrient concentration in the water is not too high, preventing root burning.
The water flap 350 has the function of adjusting the water flow direction from bottom to top, i.e. the new water body can replace the old water body from bottom to top, so that dead water is not easy to form, and plant survival is facilitated.
The running water plate 350 is provided with a chute 351, and the chute 351 penetrates through the wall of the planting pot 300. The slide bar 352 can be pulled out from the planting pot along the slide groove 351, so that the addition of the nutrient to the planting pot 300 is convenient.
The overflow 341 of the planting pot 300 is connected with the return water pipe 401. During rain, excess water in reservoir 310 flows out of overflow 341 through return line 401 to tank 100 for irrigation purposes.
When irrigation is required and the water level in the water tank 100 is insufficient, the control panel 500 opens the emergency valve 120, and water is supplied to the water tank through the fire-fighting pressure water supply pipe at this time, and irrigation is completed.
