Technical Field

[0001] The utility model relates to the technical field, and more particularly to a laboratory watering device. Background Art

[0002] In the field of modern agricultural science and technology, especially in the research of plant breeding and genetic improvement, plant cultivation in the laboratory is a key link. Traditional laboratory plant cultivation methods rely on manual operations by scientific personnel. In particular, in the breeding process of crops such as wheat, watering operations are indispensable. However, with the increase in experimental treatment groups, relying solely on manual quantitative irrigation with graduated cylinders is not only inefficient, but also easily affects the accuracy of experimental results due to improper operation. This manual operation method not only increases the labor intensity of scientific researchers, but also limits the expansion of experimental scale and the precise control of experimental data.

[0003] Many laboratories have begun experimenting with automated equipment to assist with plant cultivation, but these devices are often limited in functionality and unable to meet the demands of conducting multiple experiments simultaneously. In complex situations where different experimental groups require different treatments, existing automated equipment cannot flexibly adjust watering amounts and timing, compromising experimental reproducibility and comparability.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] Example 1

[0027] See Figure 1 , a laboratory watering device, including a controller 1, a liquid level relay 2, a flow meter 4, a solenoid valve 5, an adjustable overflow port 8, an adjustable nozzle 11, an experimental container, an overflow pipe 12, a water supply pipeline, a main pipeline, and a branch pipeline. One end of the main pipeline is connected to a water source. In this embodiment, the water source can be a faucet 3, and the other end is connected to the experimental container through a branch pipeline. The main pipeline is sequentially provided with a flow meter 4 and a solenoid valve 5. The flow meter 4, the solenoid valve 5 and the controller 1 are electrically or communicatively connected. In this embodiment, three groups of experimental containers are provided, corresponding to three branch pipelines. Of course, different numbers of experimental containers can also be set according to actual needs. The experimental containers are all provided with an adjustable overflow port 8. The position of the overflow port of the corresponding experimental container can be changed through the adjustable overflow port 8, thereby ensuring that the amount of water in the seedling tray 9 does not exceed the set value. The adjustable overflow port 8 is connected to the overflow pipe 12 through a redundant hose.

[0028] It should be noted that the controller 1 in this embodiment is made based on the single-chip microcomputer STM32, and the single water supply volume and water supply period can be set through the control panel on the single-chip microcomputer. The solenoid valve 5 is a commercially available normally closed solenoid valve. The controller 1 can quantitatively water the system by controlling the closing of the solenoid valve 5. The flow meter 4 can detect the flow of the main line. When the flow reaches the set value, the controller 1 controls the solenoid valve 5 to close, thereby completing the quantitative water supply to the experimental container; the liquid level relay 2 and the adjustable nozzle 11 are both commercially available parts. The liquid level relay 2 can adopt SHRIHKD DF-96D, and the adjustable nozzle 11 can adopt a quick-insert atomizing adjustable nozzle.

[0029] See Figure 1 In this embodiment, the experimental container is a seedling tray 9, the number of which is 3. Of course, other containers can also be used. The seedling tray 9 is a box structure with an open top and a circumferentially closed structure, which contains liquid. The top of the seedling tray 9 is detachably fixedly connected with a plurality of seedling boxes 10. The bottom of the seedling box 10 is provided with holes connected to the seedling tray 9 so that water can enter the seedling box 10. The seedling box 10 is filled with soil, and the capillary phenomenon of the soil can be used to achieve quantitative watering of the plants; the seedling tray 9 and the seedling box 10 can be plug-in matched. Specifically, a connecting groove adapted to the seedling box 10 is formed on the seedling tray 9, and the connecting groove and the seedling box 10 can be engaged;

[0030] See Figure 2 、 Figure 3 、 Figure 4 , the adjustable overflow port 8 includes an overflow port A plate 801, an overflow port B plate 802, an adjusting slide 8021, and a fixing screw 803. The overflow port B plate 802 can move relative to the overflow port A plate 801. The overflow port A plate 801 and the overflow port B plate 802 are fixedly connected to the seedling tray 9 by fixing screws 803. In this embodiment, the overflow port B plate 802 forms a side wall of the seedling tray 9. Four screw holes 8011 are opened on the overflow port A plate 801, which are respectively located at the four corners of the overflow port A plate 801. An adjusting port 8013 is opened on the overflow port A plate 801; a sealing ring 8012 is fixedly connected to the overflow port A plate 801 and the overflow port B plate 802, and the size of the sealing ring 8012 is larger than the adjusting slide 8021;

[0031] The overflow port B plate 802 has the same structure as the overflow port A plate 801. The adjusting slide 8021 is fixed between the overflow port A plate 801 and the overflow port B plate 802. A screw fixing port 8022 is provided on the adjusting slide 8021. The screw fixing port 8022 is formed with an external thread and a through hole is opened on it to form an overflow outlet 804. The size of the screw fixing port 8022 is adapted to the size of the adjusting port 8013 so that it can slide up and down relative to the adjusting port 8013. The screw fixing port 8022 is connected and fastened to the overflow port B plate 802 through a nut, and the nut is against the overflow port B plate 802. Of course, the overflow port A plate 801 and the overflow port B plate 802 can also be fixed by fixing screws 803, and the adjusting slide 8021 located between the overflow port A plate 801 and the overflow port B plate 802 is clamped.

[0032] See Figure 1 The main pipeline is connected to the branch pipeline through a four-way quick-plug interface 6, and the branch pipeline is connected to the seedling tray 9 and the adjustable nozzle 11 through a three-way quick-plug interface 7. The adjustable nozzle 11 is arranged above the seedling tray 9. In this embodiment, the detection end of the liquid level relay 2 is arranged in one of the seedling trays 9. Since the three branch pipelines have the same diameter, the liquid level of one of the seedling trays 9 is used as the reference liquid level.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that it can work without being connected to the controller 1, and can work through the liquid level relay 2. When the liquid level relay 2 in this embodiment is used alone to work, the use cost and operation cost can be greatly reduced. The liquid level relay 2 is a prior art product, that is, a commercially available part with a low cost, and other components are all commercially available parts.

[0035] Specifically, by setting the position information of the liquid level sensing module in the liquid level relay 2, when the water level in the seedling tray 9 drops beyond the sensing range of the liquid level sensing module in the liquid level relay 2, the liquid level relay 2 sends an electrical signal to the solenoid valve 5 to control the opening of the solenoid valve 5 and start supplying water to the seedling tray 9. When the water level reaches the sensing range of the liquid level sensing module in the liquid level relay 2, the liquid level relay 2 stops sending electrical signals to the solenoid valve 5, and the solenoid valve 5 closes, that is, the system stops supplying water. In this working mode, the method of supplying water to the plants and the control method of the adjustable overflow port 8 are the same as those in Example 1. It should be noted that the algorithms or software involved can be those in the prior art.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
