Description

Technical Field

[0001] The utility model belongs to the technical field of plant stress experimental equipment, and particularly relates to a plant stress experimental device with an automatic water control structure. Background Art

[0002] Soil moisture control in plant stress experiments is crucial, as it directly affects the accuracy and reliability of the experimental results. Appropriate soil moisture is the basis for plant physiological activities such as photosynthesis, respiration, and nutrient absorption. In stress experiments, by accurately controlling soil moisture, we can simulate the growth environment under different moisture conditions, observe the response of plants to water stress, and then study their growth and development mechanisms. Too much or too little water will have adverse effects on plants. Excessive moisture can cause root suffocation, affecting the plant's absorption of oxygen and nutrient transport; while excessive dryness can inhibit plant photosynthesis and transpiration, leading to hindered plant growth and development. Therefore, reasonable soil moisture control is the key to ensuring the accuracy of experimental results.

[0003] Most cultivation devices in the prior art are planting pots. During the experiment, people mostly use quantitative watering pots to manually water the plants in a quantitative manner. It is easy for people to forget, causing the plants to lack water and thus affecting the accuracy of the experimental results. In addition, people need to rest at night, and the planting pots / quantitative watering pots do not have a structure that automatically detects soil moisture and replenishes water, requiring manual operation. Therefore, it is difficult for existing cultivation devices to achieve real-time monitoring and automatic control of water replenishment, which is inconvenient to use. Based on this, we provide a plant stress experimental device with an automatic water control structure to solve the above technical problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a plant stress experimental device with an automatic water control structure in order to solve the above problems, aiming to solve the technical problem that the cultivation device in the prior art does not have a structure for automatically detecting soil moisture and replenishing water, making it difficult to achieve real-time monitoring and automatic control of water replenishment operations.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A plant stress experimental device with an automatic water control structure includes a water storage tank, a weighing base disposed on the top of the water storage tank, a rotating base disposed on the top of the weighing base, a water collection tray disposed on the top of the rotating base and driven to rotate by the rotating base, a planting pot placed in the water collection tray, a soil moisture sensor placed in the planting pot, an irrigation component disposed on the top of the planting pot, a water recovery component located in the water collection tray, and a controller;

[0007] The controller is used to control the irrigation component to replenish water to the plants and control the water recovery component to recycle excess water according to the soil moisture signal measured by the soil moisture sensor.

[0008] As a further optimization scheme of the present invention, the rotating base includes a supporting base and a rotating motor arranged inside the supporting base. The output shaft of the rotating motor extends out of the top of the supporting base and is connected to the bottom of the water collecting tray. The bottom of the water collecting tray and the top of the supporting base are rotatably connected through bearings.

[0009] As a further optimized solution of the present invention, the planting pot includes a pot body, at least one bottom support leg arranged at the bottom of the pot body, and a plurality of drainage holes opened at the bottom of the pot body.

[0010] As a further optimization scheme of the present invention, the irrigation assembly includes a water delivery pump, a water delivery pipe connected to the output end of the water delivery pump, a sprinkler head connected to the output end of the water delivery pipe and located on the top of the basin body, and a fixing rod provided on the top of the water storage tank body for supporting and fixing the water delivery pipe and the sprinkler head. The input end of the water delivery pump extends into the interior of the water storage tank body.

[0011] As a further optimization scheme of the present invention, the water recovery component includes a filter element arranged at the bottom of the water collection tray, a water suction head arranged outside the filter element, a water suction pipe connected to the output end of the water suction head, a drainage pump connected to the output end of the water suction pipe, and a drainage pipe connected to the output end of the drainage pump. The leakage holes are all located within the protection range of the filter element, and the output end of the drainage pipe extends to the inside of the water storage tank.

[0015] 1) The utility model can automatically control the irrigation component to replenish water to the plants through the soil moisture signal measured by the soil moisture sensor, and can replenish water to the plants in time to avoid water shortage in the plants, thereby ensuring accurate control of soil moisture during the plant stress experiment. It has a high degree of automation, can also reduce manual workload, and is easy to use;

[0016] 2) When the irrigation assembly is used to irrigate the planting pot, the rotating base can be used to drive the planting pot to rotate.

[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] like Figure 1-3As shown, a plant stress experimental device with an automatic water control structure includes a water storage tank 1, a weighing base 6 provided on the top of the water storage tank 1, a rotating base 7 provided on the top of the weighing base 6, a water collection tray 8 provided on the top of the rotating base 7 and driven to rotate by the rotating base 7, a planting pot 9 placed in the water collection tray 8, a soil moisture sensor 10 placed inside the planting pot 9, an irrigation component provided on the top of the planting pot 9, a water recovery component located inside the water collection tray 8, and a controller 17;

[0024] The controller 17 is used to control the irrigation component to replenish water to the plants and control the water recovery component to recycle excess water according to the soil moisture signal measured by the soil moisture sensor 10.

[0025] It should be noted that, in this embodiment, the signal output ends of the weighing base 6 and the soil moisture sensor 10 are connected to the signal input end of the controller 17 , and the signal input end of the rotating motor 72 is connected to the signal output end of the controller 17 .

[0026] The controller 17 can control the irrigation component to replenish water to the plants based on the soil moisture signal measured by the soil moisture sensor 10. The principle is that after the water evaporates, the soil moisture decreases. When the measured soil moisture signal is within the set range, the controller 17 can control the irrigation component to replenish water to the plants.

[0027] In plant stress experiments, soil moisture control requires high standards. Therefore, being able to accurately detect soil moisture and control irrigation components to replenish water to plants in a timely manner is the key to the smooth progress of plant stress experiments. Real-time monitoring of soil moisture and timely replenishment of water ensure that the results of plant stress experiments are highly accurate and reliable.

[0028] In addition, the components above the weighing base 6, including the planting pot 9 and the plants planted therein, can be weighed as a whole, and the growth weight of the planted plants can be calculated in combination with the humidity data measured by the soil moisture sensor 10.

[0029] Preferably, the rotating base 7 includes a supporting base 71 and a rotating motor 72 arranged inside the supporting base 71. The output shaft of the rotating motor 72 extends out of the top of the supporting base 71 and is connected to the bottom of the water collecting tray 8. The bottom of the water collecting tray 8 is rotatably connected to the top of the supporting base 71 through a bearing. When replenishing water to the plants, the rotating motor 72 is started. The operation of the rotating motor 72 will drive the water collecting tray 8 and the planting pot 9 placed inside the water collecting tray 8 to rotate together, making it convenient to replenish water to the soil in a circle inside the planting pot 9, so that the replenished water is distributed more evenly.

[0030] Preferably, the planting pot 9 includes a pot body 91, at least one bottom leg 92 provided at the bottom of the pot body 91, and several drainage holes 93 opened at the bottom of the pot body 91. For some plants, the soil needs to be thoroughly irrigated each time with water, which will result in excessive watering. At this time, the excess water will fall to the bottom of the water collecting tray 8 through the drainage holes 93. The bottom legs 92 can separate the bottom of the pot body 91 from the bottom of the water collecting tray 8 by a distance, so that the excess water can seep downward through the drainage holes 93. For plants that do not need to irrigate the soil each time with water, it is sufficient to directly control the amount of water used for each additional irrigation.

[0031] Preferably, the irrigation assembly includes a water delivery pump 3, a water delivery pipe 4 connected to the output end of the water delivery pump 3, a sprinkler head 5 connected to the output end of the water delivery pipe 4 and located at the top of the basin body 91, and a fixing rod 2 provided on the top of the water storage tank body 1 for supporting and fixing the water delivery pipe 4 and the sprinkler head 5. The input end of the water delivery pump 3 extends to the inside of the water storage tank body 1.

[0032] When the plants need to be supplemented with water, the controller 17 controls the water delivery pump 3 to extract water from the water storage tank 1 and deliver it to the sprinkler head 5 through the water delivery pipe 4, and then spray it into the basin 91 through the sprinkler head 5.

[0033] It should be noted that, in this embodiment, the spray head 5 is a spray head 5 whose size of the liquid mist can be manually adjusted.

[0034] In this embodiment, the signal input end of the water delivery pump 3 is connected to the signal output end of the controller 17. The amount of water replenished each time can be controlled by controlling the time when the water delivery pump 3 pumps water through the controller 17.

[0035] Preferably, the water recovery component includes a filter element 11 arranged at the bottom of the water collection tray 8, a water suction head 14 arranged outside the filter element 11, a water suction pipe 13 connected to the output end of the water suction head 14, a drainage pump 12 connected to the output end of the water suction pipe 13, and a drainage pipe 15 connected to the output end of the drainage pump 12. The leakage holes 93 are all located within the protection range of the filter element 11, and the output end of the drainage pipe 15 extends to the inside of the water storage tank 1.

[0036] It should be noted that, in this embodiment, the filter element 11 is a ring-shaped filter screen plate.

[0037] In this embodiment, the signal input end of the drainage pump 12 is connected to the signal output end of the controller 17 .

[0038] The excess water accumulated inside the water collection tray 8 can be operated by the drainage pump 12, and extracted using the suction head 14 and the suction pipe 13, and then transported back to the water storage tank 1 through the drainage pipe 15. Among them, the filter element 11 is used to filter out impurities such as soil and plant roots in the excess water, reducing or preventing impurities such as soil and plant roots from entering the suction head 14 and the suction pipe 13 along with the water extraction.

[0039] Preferably, the water storage tank body 1 is provided with a water inlet pipe 101 and a water outlet pipe 102, the water inlet pipe 101 is provided with a sealing cover, and the water outlet pipe 102 is provided with a switch valve. By opening the sealing cover, water can be added to the water storage tank body 1 through the water inlet pipe 101, and by opening the switch valve, the water inside the water storage tank body 1 can be discharged through the water outlet pipe 102.

[0040] Preferably, the water tank body 1 is provided with a low liquid level alarm 16 for monitoring the low liquid level inside the water tank body 1. It should be noted that, in this embodiment, the signal output end of the low liquid level alarm 16 is connected to the signal input end of the controller 17. When the water level inside the water tank body 1 is low, the staff is prompted to add water to the water tank body 1.

[0041] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
