[0028] Example 1

[0029] See attached Figure 1-3The present application provides an automatic irrigation device for rapid breeding of rapeseed in a greenhouse, comprising a support frame 1, a water tank 2 and an irrigation mechanism 3, wherein the irrigation mechanism 3 comprises a sprinkler head 301, a delivery pipe 302 and a gravity sensing plate 303, wherein the water tank 2 is connected to the sprinkler head 301 through the delivery pipe 302, and the sprinkler head 301 is connected to the support frame 1, an electric water valve 304 is arranged at the connection between the water tank 2 and the delivery pipe 302, the gravity sensing plate 303 is arranged in the middle of the support frame 1, a pressure sensor is arranged on the gravity sensing plate 303, the gravity sensing plate 303 is electrically connected to the electric water valve 304, and the delivery pipe 302 is provided with a flow control mechanism 4. This device is provided with a gravity sensing plate 303, and a planting pot planted with cabbage-shaped rapeseed is placed above the gravity sensing plate 303. After the gravity sensing plate 303 detects the weight reduction, it controls the electric water valve 304 to open. The electric water valve 304 injects the water in the water tank 2 into the delivery pipe 302. The water in the delivery pipe 302 is pumped to the sprinkler head 301 under the control of the flow control mechanism 4 to spray the planting pot. After the planting pot is sprayed with enough water, the weight increases. After the gravity sensing plate 303 senses enough pressure, it sends a signal to the electric water valve 304 to close and stop water injection. In summary, this device is provided with a gravity sensing plate 303, an electric water valve 304 and a flow control mechanism 4, so that the sprinkler head 301 can automatically replenish the spray when the planting pot lacks water, which can improve the uniformity of irrigation and save manpower.

[0030] Specifically, the support frame 1 is configured as a multi-layer structure composed of a plurality of rectangular frames 5, the middle of each layer of the rectangular frames 5 is connected to the gravity sensing plate 303, and each layer of the rectangular frames 5 is provided with the corresponding electric water valve 304, the delivery pipeline 302, the flow control mechanism 4 and the sprinkler head 301. The multi-layer structure of the device can improve space utilization and the efficiency of breeding and irrigation.

[0031] Specifically, the delivery pipeline 302 is configured as a U-shaped structure 305, and the flow control mechanism 4 is disposed at the bottom of the delivery pipeline 302. Figure 2 A three-way pipe 306 is arranged on one side of the U-shaped structure 305 close to the water tank 2. The upper end of the three-way pipe 306 is connected to the outside, the lower end of the three-way pipe 306 is connected to the delivery pipe 302, and the right side of the three-way pipe 306 is connected to the water tank 2 through the electric water valve 304. The U-shaped structure 305 enables the flow control mechanism 4 to control the flow according to the change in water pressure generated when the electric water valve 304 injects water into the U-shaped structure 305, that is, the change in the water injection height on the right side of the U-shaped structure 305 will cause the water pressure at the flow control mechanism 4 to change, and the flow control mechanism 4 controls the flow according to the water pressure.

[0032] Specifically, the flow control mechanism 4 includes a water pressure sensor 401 and an electric water pump 402, and the water pressure sensor 401 is electrically connected to the electric water pump 402. The water pressure sensor 401 provided in the device can sense the water pressure generated by the height of the water column on the right side of the U-shaped structure 305, and when the water pressure increases, the electric water pump 402 is controlled to start and deliver water to the sprinkler head 301 for irrigation.

[0033] When the planting pot lacks water, the gravity sensing plate 303 senses that the weight has been reduced to below the preset value, and the gravity sensing plate 303 controls the electric water valve 304 to start, and delivers water to the U-shaped structure 305. The water column on the right side of the U-shaped structure 305 rises, and the water pressure sensor 401 senses that the pressure has reached the preset value, and controls the electric water pump 402 to start, and delivers part of the water in the delivery pipe 302 to the sprinkler head 301 for spraying irrigation. The gravity sensing plate 303 detects the weight change. If the weight does not return to above the preset value after irrigation, the electric water valve 304 continues to open and inject water, and the above steps are repeated for irrigation. Otherwise, the water injection is stopped. By watering through the above steps, and adjusting the duration of a single start of the electric water pump 402 and the amount of water sprayed by the sprinkler head 301 according to the needs of the site, excessive irrigation can be prevented. If the gravity sensing plate 303 is used to directly control the irrigation of the sprinkler head 301, the gravity sensing plate 303 will sense that the weight has increased to above the preset value, and then send a signal to control the sprinkler head 301 to stop irrigation. The stopping of the spraying action of the sprinkler head 301 may be delayed, resulting in excessive irrigation, which will affect the breeding of Brassica napus.

[0034] Specifically, the water tank 2 is provided with a water inlet 201 at the upper part away from the support frame 1, and a switch valve 202 is provided at the water inlet 201. The water inlet 201 can be connected to a water source to replenish the water in the water tank 2 to avoid the device being unable to irrigate normally due to lack of water in the water tank 2.

[0035] Specifically, a spray valve is provided at the connection between the spray head 301 and the delivery pipe 302. The spray valve can control the switch and spray flow rate of the spray head 301, and cooperate with the electric water pump 402 to control the spray distance and height of the spray head 301 for more accurate spraying.

[0036] Specifically, the spray head 301 is arranged on the side of the support frame 1 away from the water tank 2, and the spray direction of the spray head 301 is toward the side close to the water tank 2. The spray head 301 is arranged on the side so that the entire gravity sensing plate 303 can be sprayed by one spray head 301, saving the device cost.

[0037] Specifically, the bottom of the spray head 301 is fixedly connected to the support frame 1 via a support rod 307. The support rod 307 can prevent the spray head 301 from shaking during spraying, causing the spraying position to deviate, and can improve the reliability of the device.

[0038] Example 2

[0039] Refer to the attached Figure 4 The difference between this embodiment and embodiment 1 is that the spray head 301 is arranged above the gravity sensing plate 303, and the spray direction of the spray head 301 is vertically downward toward the gravity sensing plate 303. The top of the spray head 301 is fixedly connected to the support frame 1 through a conveying pipe 302. The spray head 301 is arranged just above the gravity sensing plate 303, which can irrigate the Brassica napus more accurately and improve the irrigation effect.

[0040] Specifically, a plurality of the spray heads 301 are arranged above any of the gravity sensing plates 303, a corresponding pressure sensor is arranged below any of the spray heads 301, and the spray valve is electrically connected to the pressure sensor. By arranging a plurality of spray heads 301 and a plurality of pressure sensors, the water shortage of different Brassica napus plants can be detected separately, and targeted irrigation can be performed, further improving the reliability of the device.

[0041] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
