[0002] A glass greenhouse is a type of modern agricultural facility that uses glass as its primary light-transmitting covering material. Its structure typically consists of a high-quality steel frame and high-strength tempered glass as the covering material, offering excellent light transmission, impact resistance, and corrosion resistance. Glass greenhouses are rationally designed to withstand various natural environmental conditions, ensuring overall stability and ease of installation and maintenance. Existing glass greenhouses utilize specialized irrigation systems to ensure crop growth.

[0003] A search revealed an automatic irrigation device for a large glass greenhouse, as disclosed in announcement number CN212279112U. Its main features include: a greenhouse, an electrical control cabinet, and a soil moisture sensor; the electrical control cabinet is located inside the greenhouse, and the soil moisture sensor is also installed inside the greenhouse; a water spray pipe is located inside the greenhouse, and a nozzle is installed at the top of the water spray pipe; a pressure gauge is located at the end of the water spray pipe, and the pressure gauge is connected to the water spray pipe via a flange; a water pump is connected to the pressure gauge via a water supply pipe, and a water supply pipe valve is installed in the middle of the water supply pipe; an overflow pipe is located on the side of the water supply pipe, and an overflow pipe valve is installed in the middle of the overflow pipe; and an air humidity sensor is located inside the greenhouse.

[0004] In actual use, the applicant found that when the above-mentioned irrigation device is started, all the planting fields in the entire glass greenhouse will be irrigated as a whole. However, since the soil moisture evaporation in many areas of the planting fields is low and the humidity meets the planting needs, the planting fields will be over-irrigated and the irrigation water will be directly lost, resulting in low water resource utilization. In order to solve the above-mentioned problems, an automatic irrigation device for glass greenhouses is provided. Utility Model Content

[0010] In a preferred embodiment, an electrically controlled valve two is installed on the inlet side of the main water supply pipe, and the electrically controlled valve two is electrically connected to the PLC controller.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, soil moisture sensors in each planting area are used to detect the soil moisture in the planting field within that area, and the moisture data is transmitted to the PLC controller. The PLC controller then compares the data with a set threshold. When the soil moisture in a planting area is lower than the threshold, the PLC controller controls the corresponding electronic valve in that planting area to open, thereby irrigating that planting area.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The following will combine Figures 1-2 A detailed description of an automatic irrigation device for a glass greenhouse according to an embodiment of the present invention will be provided. Example

[0018] This utility model provides an automatic irrigation device for a glass greenhouse, as shown in the following embodiment. Figures 1 to 2 As shown, the structure includes a glass greenhouse 1, inside which are planting fields 2. The planting fields 2 are divided into multiple planting areas 3 of equal size. Each planting area 3 has a corresponding sprinkler irrigation network 4 above it. A main water supply pipe 5 is fixedly connected to the top crossbeam inside the glass greenhouse 1. Multiple branch water supply pipes 6 are installed on the main water supply pipe 5. The branch water supply pipes 6 are connected to the sprinkler irrigation network 4. In this structure, crops are planted in the planting fields 2. Water flows from the main water supply pipe 5 to the branch water supply pipes 6. The branch water supply pipes 6 supply water to the sprinkler irrigation network 4 corresponding to each planting area 3, thereby providing individual sprinkler irrigation for each planting area 3.

[0019] refer to Figures 1 to 2 As shown, an electrically controlled valve 7 is fixedly installed on the water supply pipe 6. Multiple soil moisture sensors 8 are buried in the planting fields 2 within each planting area 3. A control cabinet 9 is installed inside the glass greenhouse 1, and a PLC controller 10 is installed inside the control cabinet 9. The electrically controlled valve 7 and the soil moisture sensors 8 are electrically connected to the PLC controller 10. This structure uses the soil moisture sensors 8 in each planting area 3 to detect the soil moisture in the planting fields 2 within that planting area 3 and transmits the moisture data to the PLC controller 10. The PLC controller 10 then compares the data with a set threshold. When the soil moisture in a planting area 3 is lower than the threshold, the PLC controller 10 controls the electrically controlled valve 7 corresponding to that planting area 3 to open, thereby irrigating that planting area. The entire structure can control the irrigation of planting fields 2 in zones. Compared with the existing whole irrigation method, it can achieve precise irrigation by zone, avoid water waste caused by whole irrigation, and improve water resource utilization.

[0020] refer to Figures 1 to 2As shown, the sprinkler irrigation network 4 includes a branch pipe 11 and two hangers 12. The branch pipe 11 is connected to the branch water supply pipe 6. Sprinkler pipes 13 are fixedly connected to the branch pipe 11 at equal intervals. Multiple extension pipes 14 are fixedly connected to the sprinkler pipes 13. Sprinkler heads 15 are fixedly installed at the lower end of the extension pipes 14. The two sides of the sprinkler pipes 13 are fixedly installed on the hangers 12. The hangers 12 are fixedly installed on the inner top beam of the glass greenhouse 1. This structure uses the hangers 12 to connect the sprinkler pipes 13 to the inner top beam of the glass greenhouse 1. When irrigating, the branch water supply pipe 6 delivers water to the branch pipe 11. Then, the branch pipe 11 distributes the water to each sprinkler pipe 13. The sprinkler pipes 13 distribute the water to the extension pipes 13 and spray the water out through the sprinkler heads 15, thereby irrigating the planting area 3.

[0021] refer to Figures 1 to 2 As shown, a water pump 16 is connected to the inlet end of the main water supply pipe 5. The water pump 16 is electrically connected to the PLC controller 10. In this structure, the water pump 16 is used to pump water from the water storage tank into the main water supply pipe 5, thereby supplying water to the sprinkler system. The PLC controller 10 controls the start and stop of the water pump 16.

[0022] refer to Figures 1 to 2 As shown, an electric control valve 17 is installed on the inlet side of the main water supply pipe 5. The electric control valve 17 is electrically connected to the PLC controller 10. This structure uses the electric control valve 17 to control the opening and closing of the main water supply pipe 5, and the PLC controller 10 controls the operation of the electric control valve 17.

[0023] The implementation principle of an automatic irrigation device for a glass greenhouse according to an embodiment of this application is as follows: When in use, when the soil moisture sensor 8 in the planting area 3 detects that the soil moisture of the planting field 2 in the planting area 3 is lower than the threshold, the PLC controller 10 controls the second electric control valve 17 and the first electric control valve 7 corresponding to the planting area 3 to open, and then controls the water pump 16 to start. At this time, the water pump 16 pumps the water in the water storage tank into the main water supply pipe 5. The main water supply pipe 5 delivers the water to the branch water supply pipe 6 corresponding to the planting area 3. The branch water supply pipe 6 supplies the water to the branch water pipe 11 corresponding to the planting area 3. Then the branch water pipe 11 flows the water to each spray pipe 13 above the planting area 3. The spray pipe 13 flows the water to the extension pipe 13 and sprays the water out through the spray head 15, thereby realizing the irrigation of the planting area 3.

[0024] It should be noted that the PLC controller 10, water pump 16, electrically controlled valve 2 17, electrically controlled valve 1 7, and soil moisture sensor 8 mentioned above are all well-known devices in the art. The preferred model of the PLC controller 10 is Siemens S7-1200, and the model of the soil moisture sensor 8 is XR61-TDR2. The specific control devices and programs of the PLC mentioned above have been implemented in the art, and this application does not improve the specific control devices and programs of the PLC, so they will not be described in detail here.
