Description

Technical Field

[0001] This utility model relates to the technical field of sprinkler irrigation, and in particular to a water-saving sprinkler irrigation device. Background Technology

[0002] China is also a water-scarce country, with agriculture being a major water user. Traditional irrigation methods are highly wasteful: traditional methods such as flood irrigation have very low water utilization rates, with a large amount of water wasted during water distribution and field irrigation. Water-saving irrigation, through the use of advanced technologies and management measures, aims to achieve maximum yield or benefits with minimal water consumption, thereby improving irrigation water utilization efficiency. Its core is to meet the water requirements of crops while minimizing the ineffective consumption of water resources. Sprinkler irrigation is one of the commonly used water-saving irrigation methods.

[0003] Existing sprinkler irrigation devices mostly use fixed sprinkler heads. Since the water pressure is basically constant, the water is sprayed out in a pattern. The amount of water sprayed further away from the sprinkler head is greater than that sprayed closer to the sprinkler head. The uniformity of water distribution within the sprinkler head's spray range needs to be further improved. Due to the uneven water distribution, some areas receive excessive irrigation water, resulting in a waste of water resources and certain limitations in their use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water-saving sprinkler irrigation device that improves the uniformity of water distribution within the spraying range and reduces water waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving sprinkler irrigation device, comprising a base, an inlet pipe, a valve body mounted on the base, and an annular water distributor. The valve body has a valve cavity, and a valve plug that slides vertically within the valve cavity and fits into the valve cavity is mounted therein. A driving component is mounted on the base to provide power for the vertical sliding of the valve plug. The annular water distributor is rotatably mounted on the upper part of the valve body, and its interior communicates with the valve cavity. Multiple circumferentially distributed first nozzles are mounted on the annular water distributor, and the outlet ends of the multiple first nozzles all face obliquely upward and are arranged in a clockwise or counterclockwise direction. The output end of the inlet pipe communicates with the valve cavity. Furthermore, when the valve plug moves upward within the valve cavity, the valve plug disengages from the valve cavity, allowing water to pass through. The driving component can be an electric cylinder or similar device with a telescopic driving effect.

[0006] Preferably, the valve plug includes a plug body and a valve stem. The plug body is used to seal the valve cavity. The valve body has a cylindrical hole that fits the valve stem. The valve stem is slidably installed in the cylindrical hole. The bottom of the valve plug extends from the bottom of the valve body. The driving component includes a rotating wheel rotatably mounted on a base, a driving seat fixedly mounted on the edge of the rotating wheel, an arc-shaped driving handle hinged to the base, and a driving motor that provides power for the rotation of the rotating wheel. The bottom of the valve stem contacts the upper part of the arc-shaped driving handle. The driving seat is used to push the arc-shaped driving handle to rotate around the hinge point away from the center of the rotating wheel. A spring is installed in the valve cavity. One end of the spring abuts against the plug body, and the other end of the spring abuts against the top wall of the valve cavity. Further, the outer wall of the valve stem is sealed with packing or the like. The driving motor is preferably a speed-regulating motor. A conventional variable frequency speed-regulating motor can be used. The structure and control principle of the speed-regulating motor will not be further limited or described here.

[0007] Preferably, it further includes a connecting pipe and at least two second nozzles. The outer wall of the rotor has multiple blades, and the two second nozzles are located on both sides of the rotor. The blades are skewed clockwise or counterclockwise and evenly distributed. One end of the connecting pipe is connected to the inlet pipe, and the other end is connected to the input end of the second nozzle. Further, the outlet ends of both second nozzles face the center of the rotor. Further, the diameter of the connecting pipe is smaller than the diameter of the inlet pipe, and the diameter of the connecting pipe can be 1 / 4 to 1 / 3 of the inlet pipe diameter. More specifically, one second nozzle is fixedly installed on the edge of the arc-shaped drive handle, and a mounting handle corresponding to the arc-shaped drive handle is installed on the base. The arc-shaped drive handle and the mounting handle are located on both sides of the rotor, and the other second nozzle is fixedly installed on the mounting handle. The drive base is installed on the edge of one of the blades away from the rotor. A flow valve is installed on the connecting pipe; the flow valve can be a commercially available known product.

[0008] Preferably, it also includes a tripod, an adjusting rod screwed onto the tripod, the top of the adjusting rod being detachably connected to the base; further, the base is detachably connected to the top of the adjusting rod by bolts; the adjusting rod is preferably a threaded rod.

[0009] Preferably, an anchor is installed at the lower center of the tripod, and the bottom of the anchor is at least 15cm below the bottom of the tripod.

[0010] Preferably, the annular water distributor includes a three-way pipe and an annular pipe. The two output ends of the three-way pipe are respectively connected to the inside of the annular pipe. The three-way pipe is located in the middle of the annular pipe, and the bottom input end of the three-way pipe is rotatably sealed to the valve body. Further, the bottom input end of the three-way pipe is rotatably sealed to the valve body through a rotary sealing joint. The rotary sealing joint can be a mechanical shaft seal joint or a packing seal joint.

[0011] Preferably, a ball bearing is rotatably mounted on the drive seat; further, the drive seat is movably connected to the arc-shaped drive handle via the ball bearing.

[0012] Compared with the prior art, this utility model provides a water-saving sprinkler irrigation device with the following beneficial effects: This water-saving sprinkler irrigation device connects the inlet pipe to an external pressurized water source. Pressurized water enters the valve cavity of the valve body through the inlet pipe. When the driving component moves the valve plug from bottom to top, the gap between the valve plug and the valve cavity gradually increases, and the amount of water entering the annular water distributor gradually increases. This causes the water in the annular water distributor to be sprayed from near to far through the first nozzle. When the valve plug moves from top to bottom, the water sprayed from the first nozzle is sprayed from far to near. When the water pressure at the first nozzle increases, the sprayed water will generate a reverse thrust on the annular water distributor, causing the annular water distributor to rotate. When the water pressure in the annular water distributor decreases, the annular water distributor can continue to rotate under the action of inertia. This, combined with the spraying of water from near to far and from far to near, improves the uniformity of water distribution within the spraying range and reduces water waste.

[0023] For details, please refer to Figure 4 A ball bearing 21 is rotatably mounted on the drive seat 9; furthermore, the drive seat 9 is movably connected to the arc-shaped drive handle 10 via the ball bearing 21.

[0024] For details, please refer to Figure 2 as well as Figure 5It also includes a connecting pipe 13 and at least two second nozzles 14. Multiple blades 15 are provided on the outer wall of the rotor 22. The two second nozzles 14 are located on both sides of the rotor 22. The blades 15 are skewed clockwise or counterclockwise and evenly distributed. One end of the connecting pipe 13 is connected to the inlet pipe 2, and the other end of the connecting pipe 13 is connected to the input end of the second nozzle 14. Furthermore, the outlet ends of both second nozzles 14 face the center of the rotor 22. Furthermore, the diameter of the connecting pipe 13 is smaller than the diameter of the inlet pipe 2. The diameter of pipe 3 can be 1 / 4 to 1 / 3 of the diameter of inlet pipe 2; more specifically, one second nozzle 14 is fixedly installed at the edge of the arc-shaped drive handle 10, and a mounting handle corresponding to the arc-shaped drive handle 10 is installed on the seat 1. The arc-shaped drive handle 10 and the mounting handle are located on both sides of the rotary wheel 22, and another second nozzle 14 is fixedly installed at the mounting handle; the drive seat 9 is installed on the edge of one of the blades 15 away from the rotary wheel 22; a flow valve is installed on the connecting pipe 13, and the flow valve can be a conventional known product on the market.

[0025] The water-saving sprinkler irrigation device provided in this embodiment uses a drive motor 11 to rotate a rotating wheel 22. The rotation direction of the rotating wheel 22 can be referenced. Figure 4 As indicated by the arrow, the rotating wheel 22 drives the drive seat 9 to rotate during its rotation. The drive seat 9 gradually pushes the arc-shaped drive handle 10 upward around the hinge point, thereby pushing the valve stem 7 upward along the cylindrical hole 8, achieving upward driving of the plug 6. When the drive seat 9 disengages from the arc-shaped drive handle 10, the plug 6 moves downward and resets under the action of the spring 12, thus achieving cyclical up-and-down driving of the valve plug. The ball bearing 21 reduces the friction between the drive seat 9 and the arc-shaped drive handle 10, thereby reducing the rotational resistance of the rotating wheel 22. When using... When the tripod is in use, the amount of water sprayed below and near the annular water distributor is small. However, the pressurized water flow sprayed through the connecting pipe 13 and the second nozzle 14 (the outflow pressure at the second nozzle 14 shall not be less than 0.3 MPa) is sprayed onto the blades 15. As the drive motor 11 drives the rotating wheel 22, it can drive the blades 15 to rotate. The pressurized water flow sprayed onto the blades 15 is further splashed and dispersed. At the same time, the centrifugal force generated during the rotation of the blades 15 throws the splashed water droplets to the surroundings, further ensuring the uniformity of water distribution below and near the sprinkler device.

[0026] The water-saving sprinkler irrigation device provided by this utility model is used as follows: The inlet pipe 2 is connected to an external pressurized water source (or the output end of an external booster pump). Pressurized water enters the valve cavity 4 of the valve body 3 through the inlet pipe 2. The drive motor 11 drives the rotating wheel 22 to rotate. The ball bearing 21 on the drive seat 9 contacts the arc-shaped drive handle 10 and pushes the arc-shaped drive handle 10 to rotate upward around the hinge point. The arc-shaped drive handle 10 pushes the valve rod 7 upward, and the gap between the plug 6 and the valve cavity 4 gradually increases. The amount of water entering the annular water distributor gradually increases, so that the water in the annular water distributor is sprayed out from near to far through the first nozzle 5. When the drive seat 9 is disengaged from the arc-shaped drive plate, the spring 12... When the valve plug moves from top to bottom, the gap between the plug body 6 and the valve cavity 4 gradually decreases. The water sprayed from the first nozzle 5 sprays from far to near. When the water pressure at the first nozzle increases, the sprayed water will generate a reverse thrust on the annular water distributor, causing the annular water distributor to rotate. When the water pressure in the annular water distributor decreases, the annular water distributor can continue to rotate under the action of inertia. Some of the water in the inlet pipe 2 is sprayed out through the connecting pipe 13 and the second nozzle 14 and forms splash water droplets after contacting the blade 15. The centrifugal force generated during the rotation of the blade 15 causes the water droplets to be further dispersed around the sprinkler device, thus achieving uniform sprinkler irrigation in the sprinkler area.
