Description

Technical Field

[0001] This invention belongs to the field of plant irrigation technology, specifically relating to an intelligent irrigation system for greenhouses. Background Technology

[0002] Effective irrigation is essential for greenhouse vegetable cultivation. However, current irrigation systems are generally operated manually, with water pipes dragged to designated locations for irrigation. This method is complex, requiring the water pipes to be stretched and pulled, causing significant inconvenience to operators, resulting in low efficiency and uneven irrigation.

[0003] To address the aforementioned problems, spraying devices are commonly used to irrigate crops in greenhouses. Currently, the number of nozzles and the distance between them in most spraying devices are fixed. For example, patent application number CN201820504960.5 discloses a three-dimensional intelligent irrigation system suitable for greenhouses. This system involves two water pipes installed on opposite sides of the greenhouse, each with multiple sprinklers fixed at intervals. Irrigation is controlled by a control box. However, when planting different plants, the position of each plant cannot be adjusted accordingly. Furthermore, to improve the spraying effect, multiple nozzles are typically used, increasing spraying costs and making it difficult to individually control the opening and closing of each nozzle, resulting in cumbersome operation. Summary of the Invention

[0004] To address the aforementioned problems, this invention aims to provide an intelligent irrigation system for greenhouses.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A smart irrigation system for greenhouses includes a connected dispensing device and a spraying device.

[0007] The spraying device includes a second water supply pipe, and multiple connector assemblies are provided along the length of the second water supply pipe;

[0008] The bracket is located below the second water supply pipe, and the connector assembly is located between the second water supply pipe and the bracket;

[0009] The nozzle is slidably connected to the bracket via a mounting head, and the mounting head is in contact with the bracket.

[0010] A first magnetic block is provided on one side of the top of the mounting head, and a second magnetic block that attracts the first magnetic block is provided at the bracket corresponding to each connector assembly.

[0011] The connector assembly includes a first connector and a second connector that are sequentially connected to the second water supply pipe; both the first connector and the second connector are hollow inside and can be detachably connected.

[0012] The second connector is equipped with a filter screen, and below the filter screen is a receiving cavity. At the bottom of the receiving cavity is a circular arc-shaped block, and in the middle of the arc-shaped block is an opening for water to flow through.

[0013] The arc-shaped block is equipped with matching balls; a third magnetic block for attracting the balls is provided on the mounting head. The third magnetic block is located on the other side of the top of the mounting head via a connecting rod, and the connecting rod is perpendicular to the side wall of the second connector.

[0014] A groove adapted to the second connector is provided on the top of the mounting head, and a vertically arranged drain hole is provided below the groove, which is connected to the nozzle.

[0015] An intake chamber is provided inside the drain hole, and a detachable air tube is connected to the intake chamber. The air tube passes through the mounting head and the bracket in sequence and extends outward to connect with the air pump.

[0016] Two opposing brackets are installed below the second water supply pipe. The cross-section of the brackets is U-shaped. The length of the brackets is parallel to the length of the second water supply pipe.

[0017] The mounting head is rectangular and is installed between two opposing brackets.

[0018] The mixing device includes a mixing tank, a fertilizer tank, and a clean water tank; the mixing tank is connected to the clean water tank and the fertilizer tank respectively through conveying pipes; a conveying pump and a pressure gauge are installed on the conveying pipes; a first water delivery pipe connected to a second water delivery pipe is installed on the mixing tank.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The present invention discloses an intelligent irrigation system for greenhouses, wherein the mounting head and the nozzle are connected, and the mounting head can slide along the length of the support. The spacing and position of the nozzles can be adjusted by moving the mounting head, which is more convenient when spraying plants in different locations. Compared with fixed nozzles, the number of nozzles is reduced, and the irrigation area of ​​the plants can be adjusted by moving the position of the nozzles, so that the overall irrigation is more uniform.

[0021] The second connector is equipped with ball bearings to seal the opening. With the cooperation of multiple magnets, the second water supply pipe is connected to the nozzle. The ball bearings prevent water leakage and allow the second connector to be opened and closed independently. Compared with the whole sprinkler system, which cannot control the opening of each nozzle individually, this indirectly reduces the waste of sprinkler water. Only a few specific nozzles need to be turned on.

[0022] The mounting base has an internal suction chamber that is connected to the air pipe. Water flows into the suction chamber, and the principle of a jet pump is used to send water into the nozzle, further enhancing the atomization effect of the water flow. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. All modifications, substitutions and alterations made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0030] Combined with reference Figures 1 to 4 The intelligent irrigation system for greenhouses in this invention consists of two parts: a dispensing device and a spraying device connected to the dispensing device.

[0031] The mixing device includes a water tank 11, a fertilizer tank 10, and a mixing tank 9. The mixing tank 9 is connected to the water tank 11 and the fertilizer tank 10 via a conveying pipe 12. A conveying pump 13 and a pressure gauge 14 are installed on the conveying pipe 12 between the mixing tank 9 and the water tank 11 and between the mixing tank 9 and the fertilizer tank 10, respectively. The conveying pump 13 delivers water and fertilizer into the mixing tank 9 for mixing. After mixing, the fertilizer is delivered to the spraying device through the first water delivery pipe 15 located on the mixing tank 9.

[0032] The spray device includes a second water supply pipe 1 connected to the first water supply pipe 15. Two opposing supports 2 are installed below the second water supply pipe 1. The supports 2 have a U-shaped cross-section; that is, in this embodiment, the U-shaped openings 63 of the two supports 2 are opposite each other. The length direction of the supports 2 is parallel to the length direction of the second water supply pipe 1.

[0033] Multiple connector assemblies are provided along the length of the second water supply pipe 1. The connector assemblies are located between the second water supply pipe 1 and the support 2. Each connector assembly includes a first connector 5 and a second connector 6 that are sequentially connected to the second water supply pipe 1.

[0034] Specifically, multiple first connectors 5 are evenly installed on the side of the second water supply pipe 1 facing the bracket 2. The first connectors 5 are hollow inside and communicate with the inside of the second water supply pipe 1. The first connectors 5 are threaded.

[0035] A second connector 6 is threadedly installed on the first connector 5. The interior of the second connector 6 is hollow. A filter screen 60 is horizontally arranged inside the second connector 6. A receiving cavity 61 is arranged below the filter screen 60. A ball bearing 64 is placed inside the receiving cavity 61. A circular arc-shaped block 62 is provided at the bottom of the receiving cavity 61. The curvature of the arc-shaped block 62 is adapted to the ball bearing 64. An opening 63 for water to pass through is provided in the middle of the arc-shaped block 62. The ball bearing 64 can block the opening 63 under normal conditions.

[0036] An installation head 4 is evenly placed between two opposing brackets 2. The installation head 4 is rectangular and is in contact with the bracket 2. The installation head 4 can slide along the length of the bracket 2. A nozzle 3 is vertically installed below the installation head 4. A groove 42 for the second connector 6 to be inserted is provided at the middle of the top of the installation head 4. A vertically arranged drain hole 43 is provided below the groove 42. The drain hole 43 is located at the middle vertical position inside the installation head 4 and is connected to the nozzle 3. By horizontally dragging the nozzle 3, the installation head 4 can be moved within the bracket 2.

[0037] A first magnetic block 40 is provided on one side of the top of the mounting head 4. A second magnetic block 20, which attracts the first magnetic block 40, is provided at the corresponding bracket 2 of each connector assembly. The second magnetic blocks 20 are located on the inner wall of the bracket 2. The second magnetic blocks 20 are intermittently and evenly distributed on the inner wall of the bracket 2. At the same time, each second magnetic block 20 corresponds to each first connector 5. The purpose of setting the second magnetic blocks 20 to correspond to the first connector 5 is that, since the bracket 2 is relatively long, when moving the mounting head 4, water will only flow from the second connector 6 into the interior of the mounting head 4 when the mounting head 4 is moved directly below the first connector 5, that is, when the first magnetic block 40 is moved directly below the second magnetic block 20. Under these conditions, the mounting head 4 will move towards the second connector 6. At this time, the operator can feel the mounting head 4 moving upward, thus letting the operator know that the mounting head 4 has moved to the designated position and is installed in place.

[0038] Drag the nozzle 3 along the length of the bracket 2. When the mounting head 4 moves directly below the second connector 6, the first magnetic block 40 and the second magnetic block 20 attract each other, thereby driving the mounting head 4 to move toward the second connector 6, so that the second connector 6 aligns with the groove 42 of the mounting head 4, thus connecting the mounting head 4, the nozzle 3, and the second water supply pipe 1.

[0039] Under the influence of gravity, the ball bearing 64 falls vertically to the arc-shaped block 62, sealing the opening 63 of the second connector 6. At this time, the impact force of the water flow in the second water supply pipe 1 will create an impact force on the ball bearing 64, firmly sealing the opening 63 of the second connector 6. A connecting rod 7 is horizontally fixed on the other side of the top of the mounting head 4. In this embodiment, the connecting rod 7 is arranged in a "7" shape, with one end horizontally positioned and perpendicular to the side wall of the second connector 6. A third magnetic block 41 for attracting the ball bearing 64 is provided at the end of the connecting rod 7. When the mounting head 4 moves toward the second connector 6 under the action of the first magnetic block 40 and the second magnetic block 20, the third magnetic block 41 at the end of the connecting rod 7 will move vertically along the outer wall of the second connector 6. Under the magnetic force of the third magnetic block 41, the ball 64 is attracted by the third magnetic block 41 and moves toward the direction of the third magnetic block 41. Then the opening 63 of the second connector 6 is opened, and the water flow will flow from the second water supply pipe 1 through the first connector 5 and the second connector 6 into the nozzle 3 and spray out from the nozzle 3.

[0040] An intake chamber 8 is provided inside the drain hole 43. A detachable air pipe 81 is connected to the intake chamber 8. The air pipe 81 passes through one side of the mounting head 4 and the bracket 2 in sequence and extends outward to connect with the air pump.

[0041] Specifically, an air pipe 81 is connected to one side of the mounting head 4. The air pipe 81 extends outward from the bracket 2 to connect with the air pump. A groove is provided on one side of the bracket 2 for the air pipe 81 to pass through. The air pipe 81 can be detached from the mounting head 4. The air pipe 81 is connected to the air pump. By adding gas and adjusting the gas flow rate, the water sprayed from the nozzle 3 can have a certain impact force and can make the water droplets form a mist, which can be evenly distributed on the plant to achieve the effect of even spraying of the plant.

[0042] In this invention, the mounting head 4 is connected to the nozzle 3, and the mounting head 4 can slide along the length of the bracket 2. By moving the mounting head 4, the spacing and position of the nozzle 3 can be adjusted, which is more convenient when spraying plants in different positions. Compared with fixed nozzles 3, the number of nozzles 3 is reduced, and the irrigation area of ​​the plants can be adjusted by moving the position of the nozzles 3, so that the overall irrigation is more uniform.

[0043] When the position of the nozzle 3 needs to be adjusted, the mounting head 4 is moved to slide within the bracket 2. At this time, the mounting head 4 is first moved downward to disengage it from the second connector 6. Under the action of water pressure in the second water supply pipe 1, the ball 64 in the second connector 6 will be pushed by the water to the arc block 62, sealing the opening 63 and preventing leakage. After the nozzle 3 moves to the designated position, the mounting head 4 is pushed upward. At this time, under the action of the first magnetic block 40 and the second magnetic block 20, the mounting head 4 docks with the second connecting head 6. The connecting rod 7 on the mounting head 4 will also move upward along the outer wall of the second connecting head 6. Under the action of the third magnetic block 41, the ball 64 moves to the side of the third magnetic block 41, and the opening 63 of the second connecting head 6 is exposed. The water in the second water supply pipe 1 enters the nozzle 3 through the mounting head 4. Therefore, the second connecting head 6 can be opened and closed individually during the movement of the nozzle 3. Compared with the whole sprinkler equipment, the opening of each nozzle 3 can be controlled individually, thereby indirectly reducing the waste of sprinkler water. Only one or a few specific nozzles 3 need to be opened.

[0044] The mounting base has an internal suction chamber 8 that is connected to the air pipe 81. Water flows into the suction chamber 8, and the principle of the jet pump is used to send water into the nozzle 3, which further enhances the atomization effect of the water flow.

[0045] The irrigation system operates as follows: Water in the water tank 11 and fertilizer in the fertilizer tank 10 are mixed in a specific ratio and transported to the mixing tank 9 via the delivery pipe 12. The mixture is then stirred and combined in the mixing tank 9. After mixing, the fertilizer solution is delivered to the second water delivery pipe 1 via the first water delivery pipe 15. The bracket 2 is installed directly above the plant to be sprayed, and the second water delivery pipe 1 is located directly above the bracket 2. When spraying the plant at a designated location, the nozzle 3 is dragged along the length of the bracket 2. Once the nozzle 3 reaches the desired spray position, the mounting head 4 is pushed upwards. At this point, under the action of the first magnetic block 40 and the second magnetic block 20, the mounting head 4 moves upwards, and the groove 42 of the mounting head 4 aligns with the second connecting head 6. Then, under the action of the third magnetic block 41, the ball bearing 64 moves towards the third magnetic block 41. The fertilizer solution flows through the opening 63 of the second connecting head 6 and is sprayed out from the nozzle 3 after passing through the drain hole 43. When the fertilizer liquid is sprayed out from the nozzle 3, the air pump is turned on, and the gas enters the suction chamber 8 through the air pipe 81. Using the principle of the jet pump, the water is then sprayed out.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention.
