Description

[0001] This application is a divisional application of application number 202311016972.5, filed on August 14, 2023, with the invention title "An Agricultural Information Irrigation Device" at the time of filing. Technical Field

[0002] This invention belongs to the field of agricultural irrigation technology, specifically relating to an irrigation device containing an external gas source and its usage method. Background Technology

[0003] Internet of Things (IoT)-based information agriculture represents an advanced stage of agricultural production. It integrates emerging technologies such as the Internet, mobile Internet, cloud computing, and the Internet of Things. Relying on various sensor nodes deployed at agricultural production sites, it utilizes the Internet to remotely and automatically irrigate crops in greenhouses, greatly reducing the intensity of irrigation work.

[0004] For example, Chinese patent CN111183825A discloses a greenhouse irrigation device based on agricultural internet control, relating to the field of agricultural internet technology. This greenhouse irrigation device based on agricultural internet control includes a guide rail column, with a threaded rod rotatably connected inside the guide rail column. A motor is driven to the left end of the threaded rod. A bracket is fixedly installed on the left side of the top of the guide rail column, and a drag chain is rotatably connected to the top of the bracket. A buckle is fixedly installed at the top of the drag chain. This greenhouse irrigation device based on agricultural internet control can achieve comprehensive irrigation of crops in the greenhouse by controlling the motor, and can control the amount of water used for irrigation, avoiding the use of a large number of components in traditional irrigation systems and reducing manufacturing costs.

[0005] However, the above solution has the following shortcomings: Although the Chinese patent with publication number CN111183825A uses a motor as the power source to make the sprinkler discs perform irrigation operations, in actual agricultural irrigation, due to the large area to be irrigated, it is usually necessary to connect a large number of sprinkler discs below the water supply pipe. A large number of sprinkler discs require the same number of motors, which is unfavorable in terms of usage cost and subsequent maintenance. At the same time, the irrigation range of liquid water thrown out by the centrifugal rotation of the counterweight ball is affected by the rotation speed, the inlet water volume, and the size of the gap at the outlet end. How to further improve the sprinkler disc, eliminate the motor components, and spray the inflowing liquid water out in a wide-area irrigation manner is the direction that needs to be improved at present. Summary of the Invention

[0006] The purpose of this invention is to provide an irrigation device containing an external gas source and a method for using it, so as to solve the problems existing in the above-mentioned background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An irrigation device with an external air source includes a water supply pipe connected to the drain end of a water pump body. The water supply pipe is connected to a sprinkler box via several water guide pipes arranged in a continuous manner. Sprinkler nozzles are arranged on the four sides of the sprinkler box. A transmission box is fixedly installed in the middle of the inner side of the sprinkler box. The four sides of the transmission box are all pre-set with open portions, and an air-push rotating assembly is installed inside the transmission box.

[0009] The outer sealing cover of the open part is provided with an expandable sleeve. A mixing plate is transversely arranged through the side wall of the expandable sleeve. A liquid pushing plate facing the water spray nozzle is sleeved on the outside of the mixing plate. An annular frame connected to the water spray nozzle is sleeved around the outer periphery of the transmission box inside the water spray box. The expandable sleeve, mixing plate and liquid pushing plate extend to the inner side of the annular frame. An inlet is arranged circumferentially on the annular frame. A sealing block for temporarily blocking the inlet is provided on the mixing plate. The air-driven rotary assembly can drive the mixing plate to perform left and right reciprocating motion under the blowing of an external air source.

[0010] When the mixing plate moves outward, the sealing block temporarily shields the liquid inlet, and the external air source of the air-push rotating assembly is discharged from the mixing plate side. At the same time, the expandable sleeve deforms and expands, and with the cooperation of the liquid-push plate, it sprays the liquid water in the annular frame from the spray nozzle end at a high flow rate over a wide area.

[0011] Preferably, the air-driven rotary assembly includes an air inlet box disposed on the bottom end face of the sprinkler box. The air inlet side of the air inlet box is connected to an external air source device through an air guide pipe assembly, and a drain valve body is connected to the other side wall of the air inlet box. A rotating blade shaft is vertically disposed inside the air inlet box. The rotating blade shaft consists of a bottom blade and an upper rotating shaft. The air discharged through the air guide pipe assembly can drive the rotating blade shaft to rotate in a specific direction, and the upper extension end of the rotating shaft passes through a bearing hole to the inside of the transmission box.

[0012] Preferably, the air-driven rotary assembly further includes a pushing inclined block arranged circumferentially on the outer side of the upper extension end of the rotary blade shaft, and a pushed arc block is provided at the inner end of the mixing plate. When the rotary blade shaft rotates, the pushed arc block contacts the inclined surface of the pushing inclined block and performs a horizontal pushing motion.

[0013] Preferably, the mixing plate is provided with a supporting arc plate to provide support after the expandable sleeve is deformed and expanded. The outer wall of the mixing plate is provided with a mixing groove. The upper and lower parts of the expandable sleeve are respectively provided with an auxiliary flow liquid inlet channel and an auxiliary flow air inlet channel, which are connected to the mixing groove. The top of the transmission box and the annular frame form a liquid inlet chamber connected to the water guide pipe. The liquid inlet end of the auxiliary flow liquid inlet channel is connected to the top wall of the transmission box and is connected to the liquid inlet chamber. The top of the air inlet box is provided with an exhaust ring groove on the wall opposite to the bottom end of the sprinkler box. The exhaust ring groove is connected to the auxiliary flow air inlet channel. The inner side of the mixing groove is provided with a flow guiding arc block to limit the flow direction of the gas discharged into the auxiliary flow air inlet channel.

[0014] Preferably, the mixing plate is provided with a vertical plate, and a sleeve rod is slidably inserted through the upper part of the side wall of the vertical plate. A reset spring sleeve rod is movably inserted into the groove of the sleeve rod, and the inner end of the reset spring sleeve rod is fixedly set on the inner side wall of the sprinkler box. The free end of the spring on the reset spring sleeve rod is fixedly sleeved on the vertical plate. The spring on the reset spring sleeve rod generates a spring thrust in the reset direction on the mixing plate through the vertical plate.

[0015] Preferably, the sleeve rod is provided with a limit stop, and the top wall of the annular frame is provided with a fixing plate. The sleeve rod slides through a preset hole in the fixing plate, and an inner push spring is sleeved on the sleeve rod between the limit stop and the fixing plate. The outer wall of the sealing block is provided with a water-receiving groove to bear the thrust of the water discharged from the water guide pipe. When the mixing plate moves outward, the sealing block is pushed by the water-receiving groove and the inner push spring and blocks the liquid inlet. When the mixing plate moves inward, the spring on the reset spring sleeve indirectly generates a reset thrust on the mixing plate, and at the same time, the vertical plate pushes the limit stop and separates the sealing block from the liquid inlet.

[0016] Preferably, the inner side of the annular frame is provided with several partitions to separate adjacent expandable sleeves, and the outlet end of the mixing tank is provided with a guide plate to discharge the discharged gas-liquid mixture toward the corresponding water spray nozzle.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the mixing plate moves outward, the blocking block moves inward under the action of water thrust and internal push spring in the water-receiving groove, and temporarily blocks the liquid inlet. At the same time, the mixing plate drives the push plate to move outward, which can generate water thrust at the spray nozzle end. The gas discharged from the external air source equipment of the air-push rotating component is discharged from the mixing groove end on the side of the mixing plate through the air guide pipe group, the exhaust ring groove and the auxiliary flow air inlet in sequence. As the gas flows in the mixing groove, a negative pressure suction will be generated in the auxiliary flow liquid inlet section. At the same time, the liquid water discharged from the water guide pipe will be discharged into the mixing groove through the auxiliary flow liquid inlet. Since the internal space volume of the annular frame is fixed, the expandable sleeve will deform and expand, and with the cooperation of the push plate, the liquid water in the annular frame will be sprayed out from the spray nozzle end at a high flow rate over a wide area.

[0019] When the mixing plate moves inward, the spring on the return spring sleeve indirectly generates a push force in the return direction on the mixing plate. At the same time, the vertical plate pushes the limiting block and separates the sealing block from the liquid inlet. Liquid water is discharged into the water pipe and quickly replenishes the liquid water in the annular frame through the liquid inlet. This invention only requires a separate external air source device to spray the irrigation water in the sprinkler box through the air pipe group. It has the characteristics of saving operating costs and facilitating subsequent maintenance, and spraying the flowing liquid water in a large-area irrigation manner. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Please see Figure 1-10 The present invention provides a technical solution:

[0033] Example 1:

[0034] An agricultural information irrigation device includes a water supply pipe 1 connected to the drainage end of a water pump body 101. The water supply pipe 1 is connected to a sprinkler box 3 by several water guide pipes 2 arranged in a continuous manner. Sprinkler nozzles 4 are arranged on the four sides of the sprinkler box 3 so that the sprinkler nozzles 4 on the four sides of the sprinkler box 3 can spray water around it. A transmission box 5 is fixedly installed in the middle of the inner side of the sprinkler box 3. The bottom end face of the transmission box 5 has an open part at the center and is fixedly in contact with the bottom end face of the inner side of the sprinkler box 3. The four sides of the transmission box 5 are all pre-set with open parts 6, and an air-push rotation component is provided inside the transmission box 5.

[0035] The outer sealing cover of the open portion 6 is equipped with an expandable sleeve 7, which is made of silicone rubber. The expandable sleeve 7 prevents liquid water flowing into the sprinkler box 3 from flowing into the transmission box 5. A mixing plate 8 is transversely installed through the side wall of the expandable sleeve 7. A liquid pushing plate 9 facing the sprinkler nozzle 4 is fitted on the outer side of the mixing plate 8. The liquid pushing plate 9 has a funnel-shaped structure that opens outward, so that when the liquid pushing plate 9 moves outward, it can generate water thrust on the end of the sprinkler nozzle 4. Inside the sprinkler box 3, an annular frame 10 that communicates with the sprinkler nozzle 4 is fitted around the outer periphery of the transmission box 5. The side end is fixed in contact with the inner wall of the water box 3. The expandable sleeve 7, the mixing plate 8 and the liquid pusher 9 extend to the inner side of the annular frame 10. The annular frame 10 is provided with a liquid inlet 11 in a circumferential manner. The liquid inlet 11 is used for the water pipe 2 to discharge liquid water into the annular frame 10. The mixing plate 8 is provided with a blocking block 12 for temporarily blocking the liquid inlet 11. The blocking block 12 has a frustum-shaped surface to facilitate the drainage of liquid water discharged from the water pipe 2. The air-push rotating component can drive the mixing plate 8 to perform left and right reciprocating motion under the blowing of an external air source.

[0036] When the mixing plate 8 moves outward, the sealing block 12 temporarily shields the liquid inlet 11, and the external air source of the air-push rotating assembly is discharged from the side of the mixing plate 8. At the same time, the expandable sleeve 7 deforms and expands, and with the cooperation of the liquid-push plate 9, the liquid water in the annular frame 10 is sprayed out from the end of the spray nozzle 4 at a high flow rate over a wide area.

[0037] Example 2:

[0038] Based on Embodiment 1, the air-driven rotary assembly includes an air inlet box 13 disposed on the bottom end face of the water spray box 3. The air inlet side of the air inlet box 13 is connected to an external air source device 201 via an air guide pipe assembly 14. The external air source device 201 can be a blower of a corresponding specification and model. The water pump body 101 and the external air source device 201 are connected through agricultural crop information collected by the information module and remote control room control. Specifically:

[0039] 1. Select the appropriate information module: Select the appropriate information module according to the type of external gas source device 201 and water pump body 101. Common information modules include Wi-Fi module, GSM module, Bluetooth module, etc.

[0040] Among them: ZigBee module: ZigBee is a low-power, short-range wireless communication protocol suitable for agricultural sensor networks and wireless communication. It can be used to monitor parameters such as soil moisture, temperature, and light intensity, and transmit the data to a centralized data acquisition system or cloud platform.

[0041] NB-IoT Module: NB-IoT is a low-power wide-area network communication technology suitable for long-distance farmland monitoring and remote control. Using an NB-IoT module, it is possible to remotely monitor and control equipment such as farmland irrigation systems and weather stations.

[0042] LoRa Module: LoRa (Long Range) is a communication technology based on low-power wide area networks, suitable for a wide range of agricultural applications, such as farmland monitoring and agricultural IoT. LoRa modules can be used to transmit environmental parameters, crop growth data, and enable interconnection between farmland equipment.

[0043] Wi-Fi Module: A Wi-Fi module is a common wireless communication module suitable for data transmission and remote control in agricultural information systems. Using a Wi-Fi module, farmers can remotely monitor and control greenhouses, irrigation equipment, etc., via smartphones or computers. In this embodiment, the linkage of a ZigBee module, an NB-IoT module, a LoRa module, and a Wi-Fi module is used to control the opening and closing of the water pump body 101 and the external air source device 201 according to the crop conditions. At the same time, the power of the water pump body 101 and the external air source device 201 can be adaptively adjusted according to the tested crop conditions. The specific power adjustment is common knowledge in the prior art and will not be elaborated here.

[0044] 2. Connect the information module: Connect the selected information module to the remote control room and the irrigation device in the crop area;

[0045] 3. Configure network connection: When using the Wi-Fi module, connect the module to the local area network of the irrigation device;

[0046] IV. Programming and Development: Based on the requirements of the selected module, write code for both the device and the cloud. Typically, a device application / firmware needs to be developed to communicate with the information module and handle remote control commands. At the same time, a cloud application / service is also needed to receive and process data and commands from the device.

[0048] VI. Remote Control Application / Interface: A mobile phone, computer, or web-based application that allows users to remotely connect to the device and perform corresponding control operations;

[0049] Furthermore, a drain valve body 15 is connected to the other side wall of the air intake box 13. The drain valve body 15 is a shut-off valve, which can discharge liquid water that has seeped into the end of the air intake box 13. A rotating blade shaft 16 is vertically arranged inside the air intake box 13. The rotating blade shaft 16 is composed of a bottom blade and an upper rotating shaft. The gas discharged into the air guide pipe assembly 14 can drive the rotating blade shaft 16 to rotate in a specific direction. A bearing hole is preset on the bottom end face of the contact part between the bottom of the transmission box 5 and the water spray box 3, and the upper extension end of the rotating shaft passes through the bearing hole to the inside of the transmission box 5.

[0050] The air-driven rotary assembly also includes a pushing block 17 circumferentially disposed on the outer side of the upper extension end of the rotating blade shaft 16, and a pushed arc block 18 disposed on the inner end of the mixing plate 8. The rotation direction of the pushing block 17 enables the inclined side of the air-driven blade shaft 16 to push and contact the pushed arc block 18. When the rotating blade shaft 16 rotates, the pushed arc block 18 contacts the inclined surface of the pushing block 17 and performs a horizontal pushing motion.

[0051] Example 3:

[0052] Further explanation based on Embodiment 2: A supporting arc plate 19 is provided on the mixing plate 8 to provide support for the expandable sleeve 7 after deformation and expansion, thereby increasing the deformation area of ​​the expandable sleeve 7. The expandable sleeve 7 is made of silicone rubber. Since the internal volume of the annular frame 10 is fixed, when the expandable sleeve 7 expands, it will press the liquid water inside the annular frame 10 into the spray nozzle 4 for accelerated discharge. A mixing groove 20 is provided on the outer wall of the mixing plate 8, and the upper and lower parts of the expandable sleeve 7 are respectively provided with an auxiliary flow liquid inlet channel 21 and an auxiliary flow air inlet channel 22, which are connected to the mixing groove 20. The inner wall surfaces of the auxiliary flow liquid inlet channel 21 and the auxiliary flow air inlet channel 22 are woven with stretchable ropes for support. The ropes 21 are made of... The auxiliary flow liquid inlet channel 21 and the auxiliary flow air inlet channel 22 are constructed using rubber material with a hardness greater than that of the expandable sleeve 7 and graphite fiber in a braided state. The top of the transmission box 3 and the annular frame 10 form an inlet chamber that is connected to the water guide pipe 2. The inlet end of the auxiliary flow liquid inlet channel 21 is connected to the top wall of the transmission box 3 and is connected to the inlet chamber. The auxiliary flow liquid inlet channel 21 is used for the inflow of some liquid water that flows into the inlet chamber from the water guide pipe 2. The top of the air inlet box 13 is provided with an exhaust ring groove 23 on the wall opposite to the bottom end of the sprinkler box 3. The exhaust ring groove 23 is connected to the auxiliary flow air inlet channel 22. The inner side of the mixing groove 20 is provided with a flow guiding arc block 24, which is used to limit the flow direction of the gas discharged into the auxiliary flow air inlet channel 22.

[0053] A vertical plate 25 is provided on the mixing plate 8. A main through hole is pre-set on the upper part of the side wall of the vertical plate 25. A sleeve rod 26 slides through the main through hole on the upper part of the side wall of the vertical plate 25. A reset spring sleeve rod 27 is movably inserted into the groove of the sleeve rod 26. The inner end of the reset spring sleeve rod 27 is fixedly set on the inner side wall of the sprinkler box 3. The free end of the spring on the reset spring sleeve rod 27 is fixedly sleeved on the vertical plate 25. The spring on the reset spring sleeve rod 27 generates a spring thrust in the reset direction on the mixing plate 8 through the vertical plate 25.

[0054] Example 4:

[0055] Further explanation based on Embodiment 3: A limit stop 28 is provided on the sleeve rod 26, the vertical plate 25 is located outside the limit stop 28, and a fixing plate 29 is provided on the top wall of the annular frame 10. The fixing plate 29 is located inside the fiber stop 28, and the sleeve rod 26 slides through the preset hole on the fixing plate 29. An inner push spring 30 is sleeved on the sleeve rod 26 between the limit stop 28 and the fixing plate 29. The spring force on the return spring sleeve rod 27 is greater than that of the inner push spring 30. The outer wall of the sealing block 12 The upper part is provided with a water-receiving groove 31, which is used to bear the thrust of the water discharged from the water guide pipe 2. The liquid water discharged from the water guide pipe 2 generates an inward thrust on the sealing block 12 through the water-receiving groove 31. When the mixing plate 8 moves outward, the sealing block 12 is pushed by the water-receiving groove 31 and the inward push spring 30 and blocks the liquid inlet 11. When the mixing plate 8 moves inward, the spring on the reset spring sleeve 27 indirectly generates a reset thrust on the mixing plate 8. At the same time, the vertical plate 25 pushes the limiting block 28 and separates the sealing block 12 from the liquid inlet 11.

[0056] The inner side of the annular frame 10 is provided with several partitions 32 to separate adjacent expandable sleeves 7, which facilitates the liquid pushing movement of the liquid pushing plates 9 in different directions within the annular frame 10. The outlet end of the mixing tank 20 is provided with a guide plate 33 to discharge the discharged gas-liquid mixture toward the corresponding water spray nozzle 4. The deflection angle of the guide plate 33 can be adaptively adjusted so that it can discharge the discharged gas-liquid mixture in a specific direction.

[0057] The working principle is as follows: The water pump body 101 and the external air source device 201 are connected to an external power supply and an information module. The gas discharged into the air duct assembly 14 can drive the rotating blade shaft 16 to rotate in a specific direction. This causes the rotating blade shaft 16 to drive the inclined surface of the pushing block 17 to circulate and push the pushed arc block 18 to make contact. Under the action of the pushing block 17, the pushed arc block 18 drives the mixing plate 8 to move horizontally in a circulatory motion. Under the support of the supporting arc plate 19, it drives the expandable sleeve 7 to expand and contract in a circulatory manner. When the mixing plate 8 moves outward, the sealing block 12 moves inward under the action of the water thrust and the internal pushing spring 30 in the water-receiving groove 31, and temporarily blocks the liquid inlet 11 to facilitate irrigation water inside the annular frame 10. Under the action of external force, the water is discharged towards the spray nozzle 4 end. At the same time, when the mixing plate 8 drives the liquid pusher 9 to move outward, it can generate water thrust on the spray nozzle 4 end. The gas discharged from the external air source device 201 of the air-push rotating component passes through the air guide pipe group 14, the exhaust ring groove 23 and the auxiliary flow inlet 22 in sequence and is discharged from the mixing groove 20 end on the side of the mixing plate 8. As the gas flows in the mixing groove 20, a negative pressure suction will be generated in the auxiliary flow inlet 21 section. At the same time, the liquid water discharged from the water guide pipe 2 will be discharged into the mixing groove 20 through the auxiliary flow inlet 21. Since the internal space volume of the annular frame 10 is fixed, the expandable sleeve 7 will deform and expand, and with the cooperation of the liquid pusher 9, the liquid water in the annular frame 10 will be sprayed out from the spray nozzle 4 end in a high flow rate over a wide area.

[0058] When the mixing plate 8 moves inward, the spring on the reset spring sleeve 27 indirectly generates a push force in the reset direction on the mixing plate 8. At the same time, the vertical plate 25 pushes the limiting block 28 and separates the sealing block 12 and the liquid inlet 11. The water guide pipe 2 discharges liquid water and quickly replenishes the liquid water in the annular frame 11 through the liquid inlet 11. This invention only requires a separate external air source device 201 to spray the irrigation water in the sprinkler box 3 through the air guide pipe group 14. It has the characteristics of saving usage costs and facilitating subsequent maintenance, and spraying the flowing liquid water in a large-scale irrigation manner.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

2. The irrigation device containing an external gas source according to claim 1, characterized in that: The inner side of the annular frame is provided with several partitions to separate adjacent expandable sleeves. The outlet end of the mixing tank is provided with a guide plate to direct the discharged gas-liquid mixture toward the corresponding water spray nozzle.

3. A method for using an irrigation device containing an external gas source, characterized in that, Using the irrigation device described in claim 2, the water pump body and the power supply terminal of the external air source device are connected to an external power supply and an information module. Gas is discharged into the air duct assembly to drive the rotating blade shaft to rotate in a directional manner. This causes the rotating blade shaft to drive the inclined surface of the pushing block to circulate and contact the pushed arc block. Under the action of the pushing inclined block, the pushed arc block drives the mixing plate to perform a horizontal circulatory pushing motion. Supported by the supporting arc plate, the expandable sleeve circulatoryly expands and contracts. When the mixing plate moves outward, the sealing block moves inward under the action of water thrust and the internal pushing spring in the water-receiving groove, temporarily blocking the inlet. This facilitates the discharge of irrigation water inside the annular frame towards the sprinkler end under external force. When the mixing plate drives the pushing plate outward, it generates water thrust on the sprinkler end. The gas discharged from the gas source equipment passes through the gas guide pipe assembly, exhaust ring groove, and auxiliary flow inlet channel in sequence, exiting from the mixing tank end on the side of the mixing plate. As the gas flows in the mixing tank, a negative pressure suction is generated in the auxiliary flow liquid inlet section. Liquid water discharged from the water guide pipe is discharged into the mixing tank through the auxiliary flow liquid inlet channel. Since the internal space volume of the annular frame is fixed, the expandable sleeve deforms and expands, and with the cooperation of the liquid pusher plate, the liquid water in the annular frame is sprayed out from the sprinkler end at a high flow rate over a wide area. When the mixing plate moves inward, the spring on the reset spring sleeve indirectly generates a reset thrust on the mixing plate. The vertical plate pushes the limit block and separates the sealing block from the liquid inlet. Liquid water is discharged into the water guide pipe and replenishes the liquid water in the annular frame through the liquid inlet. The external gas source equipment sprays irrigation water in the sprinkler box through the gas guide pipe assembly.
