Description

Technical Field

[0001] The utility model relates to the technical field of irrigation, in particular to a water conservancy irrigation device for a water conservancy project. Background Art

[0002] Water conservancy irrigation equipment used in water conservancy projects refers to various equipment and systems used for farmland irrigation, which aims to effectively utilize water resources and meet the growth needs of crops. Common water conservancy irrigation equipment includes sprinkler irrigation systems, drip irrigation systems, channel irrigation, rainwater collection systems, water supply systems and automatic irrigation control systems. Water conservancy irrigation equipment plays a vital role in modern agriculture, which can improve the yield and quality of farmland, reduce the pressure on the exploitation of groundwater resources, and achieve sustainable agricultural development.

[0003] Affected by cost control and small-scale peasant economic operations, my country currently mainly uses sprinkler irrigation to irrigate farmland. Sprinkler irrigation can better achieve a balance between controlling costs and ensuring irrigation effects. It sprays water columns into the air, forming water mist under the action of gravity to achieve the effect of irrigating crops. However, it is greatly affected by wind direction and speed, which may result in uneven irrigation. Continuously changing the water pressure through water supply parts to counteract the influence of wind will increase the working pressure of the water supply parts and reduce their service life. At the same time, the control of the water supply parts is holistic, and the adaptation to changes in wind direction is not comprehensive enough. Changing the water pressure too frequently is not conducive to ensuring the irrigation effect. Utility Model Content

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] See also Figure 1-Figure 6 , a water conservancy irrigation device for water conservancy projects, comprising a base 1, a PLC controller is installed inside the base 1, and also includes:

[0046] A water supply device 2, which is installed on the top of the base 1;

[0047] A wind measuring device 3, which is installed on the top of the water supply device 2;

[0048] A sprinkler device 4, which is installed on the top of the water supply device 2;

[0049] The supporting device 5 is installed on the outside of the base 1 .

[0050] The water supply device 2 comprises:

[0051] The water supply member 21 is fixedly mounted on the top of the base 1, and has a plurality of water outlets formed through the top and a water inlet formed through the bottom;

[0052] The water outlet pipe 22 is fixedly mounted on the top of the water supply member 21 and communicates with the inner cavity of the water supply member 21 through a plurality of water outlets provided on the top of the water supply member 21;

[0053] One end of the water inlet pipe 23 is fixedly installed at the bottom of the water supply component 21, and is connected to the inner cavity of the water supply component 21 through a water inlet opening at the bottom of the water supply component 21, and the other end thereof penetrates the base 1 and extends to the bottom of the base 1.

[0054] Specific implementation method: The user connects one end of the water inlet pipe 23 to a water source such as a ditch or a well, and starts the water supply component 21. The water supply component 21 pressurizes the water flow, and the pressurized water flows out through the water outlet pipe 22 and enters the subsequent device. The water supply component 21 includes but is not limited to a water pump, which is electrically connected to an external power supply and is also controlled by an internal PLC programming program.

[0055] The wind measuring device 3 comprises:

[0056] A vertical rod 31 is fixedly mounted at the middle of the top of the water supply member 21 and is located inside the water outlet pipe 22;

[0057] A wind speed measuring member 32, which is rotatably connected to the outer side of the vertical rod 31;

[0058] The wind direction measuring member 33 is rotatably connected to the outside of the vertical rod 31 and is located above the wind speed measuring member 32 .

[0059] Specific implementation method: Since sprinkler irrigation sprays water into the air, the water falls under the action of gravity to form water mist, thereby achieving the purpose of irrigating crops. Therefore, it is greatly affected by wind force and wind direction. The ideal irrigation range should be a circular range. Under the influence of wind force, the irrigation range is an irregular ellipse, resulting in uneven drought and flood, which is not conducive to ensuring the irrigation effect and the unified planning of irrigation operations.

[0060] One end of the wind direction measuring piece 33 is a pointing arrow, and one side is a wind deflector. Under the action of wind, one side of the wind deflector of the wind direction measuring piece 33 is deflected, driving the pointing arrow to display the wind direction, and at the same time transmitting the data to the PLC controller. The wind speed measuring piece 32 includes a plurality of hemispherical wind deflectors, which rotate under the action of wind force to measure the wind speed and transmit the data to the PLC controller. The vertical rod 31 plays a supporting role and lifts the wind speed measuring piece 32 and the wind direction measuring piece 33 for a certain distance to prevent the water mist sprayed by the sprinkler from affecting the wind measuring device 3. The wind speed measuring piece 32 and the wind direction measuring piece 33 are electrically connected to an external power supply, and are also controlled by an internal PLC programming program.

[0061] The sprinkler device 4 comprises:

[0062] A rotating member 41 is rotatably connected to the top of the water outlet pipe 22 and is in communication with the inner cavity of the water outlet pipe 22;

[0063] A plurality of spray head assemblies 42 are installed outside the rotating member 41 in a circular array.

[0064] The spray head assembly 42 includes:

[0065] The nozzle 421 is fixedly mounted on the outside of the rotating member 41, and its inner cavity is connected with the inner cavity of the rotating member 41. A plurality of through grooves are formed in the middle of the outer side of the nozzle 421, and a plurality of collars are fixedly mounted on the outer side of the nozzle 421;

[0066] Two electric telescopic rods 422, which are respectively fixedly mounted on the outside of the rotating member 41 and symmetrically located on both sides of the nozzle 421;

[0067] Two gaskets 423 are fixedly mounted on the output ends of the two electric telescopic rods 422 in a one-to-one correspondence;

[0068] A plurality of slide bars 424 are fixedly mounted on one side of the gasket 423 in a circular array, and the outer sides of the slide bars 424 are respectively slidably connected to the inner wall of the collar fixedly mounted on the outer side of the nozzle 421;

[0069] A connecting rod 425, one end of which is rotatably connected to one end of the sliding rod 424;

[0070] A folding rod 426, whose bending part is rotatably connected to the other end of the connecting rod 425, and one end of which is rotatably connected to the outer side of the nozzle 421;

[0071] An adjusting member 427, which is fixedly mounted on the other end of the folding rod 426;

[0072] The adjusting plate 428 is fixedly mounted on the outer side of the adjusting member 427 , and its outer side is fixedly connected to the inner wall of the through groove penetrating through the outer side of the nozzle 421 .

[0073] Specific implementation method: Under the impact of the pressurized water flow out of the water outlet pipe 22, the rotating member 41 rotates continuously, driving the nozzle assembly 42 to change the direction for water spraying. In order to reduce or even offset the influence of wind force on the distance and range of sprinkler irrigation, the flow rate of the water flow sprayed from the nozzle assembly 42 needs to be changed at all times. The rotating connection between the rotating member 41 and the water outlet pipe 22 is a sealed connection. This is a prior art and will not be described in detail here.

[0074] According to the Laval effect, when water flows from a wide area to a narrow area, its speed increases and its pressure increases. When water flows from a narrow area to a wide area, the pressure is released and the water speed is further accelerated. The nozzle 421 in the device is shaped like a cylinder at the water inlet end and a trumpet-shaped nozzle at the water outlet end.

[0075] After receiving the wind speed and direction information measured by the wind measuring device 3, the PLC controller controls the nozzle assembly 42 to control the water flow rate at an appropriate position to increase the flow rate to counteract the influence of wind force. The electric telescopic rod 422 is extended and retracted, and the push-pull gasket 423 moves, thereby driving the slide rod 424 to slide, realizing the rotation of the connecting rod 425 and the folding rod 426. The adjustment member 427 is convex or concave, and the adjustment plate 428 is a soft deformable material. It is convex or concave under the drive of the adjustment member 427, and the size of the inner cavity aperture of the nozzle 421 is changed. When the flow rate is increased, the aperture is reduced, and when the flow rate is reduced, the aperture is increased. The electric telescopic rod 422 is electrically connected to an external power supply, and it is also controlled by an internal PLC programming program.

[0076] After water flows in from the water inlet end of the nozzle 421, when it flows through the concave part of the adjustment plate 428, a narrow throat is formed in the inner cavity of the nozzle 421, and the water velocity increases here, and the pressure becomes greater at the same time. When flowing out of the narrow throat, the pressure is released, and the water velocity further increases. At the same time, the water is ejected outward along the central axis of the nozzle 421. The greater the wind force, the greater the concave range of the adjustment plate 428, and the greater the increase in the water velocity.

[0077] The supporting device 5 comprises:

[0078] A plurality of support arms 51, which are respectively fixedly mounted on the outside of the base 1;

[0079] A plurality of support frames 52 are rotatably connected to one end of the support arm 51 .

[0080] Specific implementation method: When using the device, the user inserts the support frame 52 into the soil. The sharp bottom of the support frame 52 is convenient for breaking the soil. By adjusting the rotation angle of the support frame 52, the height of the entire device can be adjusted. The support arm 51 plays a connecting and supporting role.

[0081] Working principle: The user uses the supporting device 5 to fix the device in an appropriate position, and the water flow is continuously pumped out and transported through the water supply device 2. At the same time, the water is pressurized to provide a certain speed. The continuous impact of the water flow causes the rotating part 41 to rotate continuously, driving the nozzle assembly 42 to rotate. The water flow speed is stable, and the rotation speed of the rotating part 41 also remains stable. The wind measuring device 3 measures the wind speed and wind direction in real time and transmits data. Under the control of the PLC controller, the nozzle assembly 42 shrinks the narrow throat in time to increase the water flow rate, thereby achieving the purpose of counteracting the influence of wind and ensuring the irrigation effect.

[0082] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
