The annular water-blocking plate 33 is connected with the spring 35, is higher than the top end of the water-blocking block 34 at a certain distance at the initial position, and can move downwards under the action of water pressure so as to control the irrigation mode. A water level line is marked on the upper part of the water storage tank 31, a circle of round small holes are formed in the lower part of the water storage tank, and if the water level of the accumulated water is lower than the water level line, water flows into the drip irrigation pipeline through a lower drainage pipe; if the accumulated water level is higher than the water level line, the water flow is sprayed out from the small holes.
As shown in fig. 6 and 7, the device is a schematic diagram of different irrigation modes (drip irrigation and sprinkling irrigation). The top of the water storage tank 31 is connected with the water supply pipeline 21 and receives external water, when the flow is small, obvious water blocking is not formed on the annular water blocking plate 33 by water flow, the water pressure is small, the water flow flows downwards into the water discharge pipe 37 along a gap in the middle of the annular water blocking plate 33 and then flows into the drip irrigation pipeline 38, and the drip irrigation mode is adopted; when the external water flow is large, water blocking in a certain depth is formed on the annular water blocking plate 33, the water level is higher than the water level line, the water pressure is large, the downward displacement of the annular water blocking plate 33 is larger than the initial distance between the annular water blocking plate and the water blocking block 34, the annular water blocking plate 33 is tightly connected with the water blocking block 34, the water flow is blocked to flow downwards, the circular small hole in the lower portion of the water storage tank 31 is just contacted with the accumulated water through the design, the water flow is sprayed outwards from the small hole, and the sprinkling irrigation mode is adopted.
As shown in fig. 4 and 5, the support rod 32 is hollow and has a drain pipe 37 inside. The upper part of the water discharge pipe 37 is connected with the water flow of the water storage tank 31, and the two ends of the lower part are connected with the drip irrigation pipeline 38. And the elevation of the inflow section of the drip irrigation pipeline 38 is higher than that of the outflow section, and the whole drain pipe 37 inclines downwards along the flow direction of the water flow, so that the inflow and the outflow are converged. Further, if the water tower is located at the intersection of the three sections of drip irrigation pipes 38, i.e. two sections of inflow and one section of outflow (or one section of inflow and two sections of outflow), the inflow section (or the outflow section) is divided into two sections according to specific conditions, and the design structure mode is consistent with the above.
As shown in fig. 6 and 8, the drip irrigation pipe 38 between two adjacent water towers is inclined downwards along the water flow direction, the height difference between the beginning end and the end of each section is a certain value, the pipe is connected to the lower end of the initial water tower 30 after the pipe 38 circulates for a circle, a water pump 39 is added at the lower end of the initial water tower 30, the water flow is pumped to a high position, the end flow of one circulation is fully utilized, and the self-circulation of the drip irrigation pipe 38 is realized.
As shown in fig. 10, the drip irrigation pipe 38 is three-hole in cross-section, i.e., in the direction of the water flow, with the pipe being spaced apart from the three holes at intervals for irrigation; the entire pipeline 38 is arranged in a rectangular shape, and the specific arrangement of the pipeline 38 can be set according to different lengths, widths, sizes and the like of the greenhouse.
The following is analyzed by a specific embodiment:
suppose a greenhouse is 20 meters long, 6 meters wide and 4 meters high, and 7 water towers total, a water storage tank 31 is 2 meters high and the diameter of the bottom surface is 0.4 meter.
In the presence of rainfall, if the intensity of the rainfall is 15mm/24h (moderate rain), the total flow down the roof can be estimated to be about 20.8cm3And/s, if the flow is divided into 6 water guide pipelines 15 to be discharged downwards, the flow of each pipeline is about 3.5cm3And/s, water blocking is not formed on the annular water blocking plate 33, and water flow can smoothly flow into the drip irrigation pipeline 38 for drip irrigation.
In the case of no rainfall, artificial water supply is performed through the water supply pipe 21. If a low flow irrigation mode is used, for example, the total water supply takes 0.002m3The flow obtained by each of the 7 water towers is about 0.29L/s, obvious water blocking cannot be formed on the annular water blocking plate 33, water flow can still flow down smoothly through the drain pipe 37, the flow rate of the water flow in the pipeline 38 is ensured to be larger, and the jet water pressure of the orifice is ensured to be larger; if a large flow irrigation mode is used, for example, the total water supply takes 0.005m3S, then 6 water towers are obtained on averageThe obtained flow rate is about 0.71L/s, obvious water blocking can be formed on the annular water blocking plate 33, larger water pressure is generated to enable the annular water blocking plate to move downwards, the sprinkling irrigation mode is started after a certain time, and a larger sprinkling irrigation coverage area can be formed because the water pressure at the bottom of the water storage tank 31 is close to 20kpa (as shown in figure 7). The input flow to the water supply line 21 can also be adjusted as desired to control the flow rate of the water in the line 38 and ultimately the spray coverage.
The undescribed parts of the present invention are the same as or implemented using prior art.
