Description

Technical Field

[0001] The utility model relates to the technical field of plant planting, in particular to a real-time monitoring device. Background Art

[0002] Indoor planting is the activity of growing plants in an indoor environment. It is usually used to grow various plants using substrates when there are no adequate outdoor planting conditions, such as indoor ornamental plants, herbs, vegetables, etc. In the process of using substrates for planting, it is necessary to regularly monitor the changes in electrical conductivity (EC) and pH (pH) to reflect whether the fertilizer and water added during the planting process meet the growth needs of the plant.

[0003] The monitoring process in the prior art is to first saturate the substrate, then sample the soaking liquid in the substrate and measure its EC / pH value. However, this method is usually used for monitoring in a small range. When it is necessary to monitor EC and pH in real time in substrate planting over a large range (such as in a vertical farm), conventional operations require a lot of manpower, which is time-consuming and labor-intensive. In addition, since the amount of water and fertilizer sprayed during indoor planting is relatively small, the amount of overflow after saturated immersion of the substrate is small. The overflowing soaking liquid is difficult to completely submerge the sensor probe. When the sensor measures, the measurement result will be inaccurate because the probe is not in sufficient contact with the sample. Utility Model Content

[0004] The purpose of the utility model is to provide a real-time monitoring device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a real-time monitoring device, suitable for a plant rack, wherein the plant rack has a drainage outlet, a drainage channel is downwardly provided on the bottom surface of the inner wall of the plant rack, the drainage channel is inwardly retracted, a converging flow channel is provided between the drainage channel and the drainage outlet, a sensor is provided in the converging flow channel, and a baffle with a top surface higher than the sensor is provided at the edge of the drainage outlet.

[0006] Preferably, the drainage channel extends in a slope toward the drain outlet.

[0007] Preferably, a converging opening is formed at the junction of the converging flow channel and the drainage channel.

[0008] Preferably, the width of the converging flow channel is smaller than the diameter of the drain outlet.

[0009] Preferably, the converging flow channel extends in a slope toward the drain outlet.

[0010] Preferably, the baffle is fixedly mounted at the end of the converging flow channel.

[0011] Preferably, the sensor is a conductivity sensor.

[0012] Preferably, the sensor is a pH sensor.

[0013] The real-time monitoring device has the following beneficial effects:

[0014] In the real-time monitoring device, after the matrix in the plant rack is saturated and soaked, the overflowed soaking liquid flows outward, is drained through the drainage channel, enters the converging flow channel and flows toward the drainage outlet. By arranging a baffle at the edge of the drainage outlet of the plant rack, the baffle increases the drainage liquid level, and the soaking liquid cannot be discharged quickly, but is gathered in the converging flow channel. The gathered soaking liquid submerges the probe of the sensor, so that the probe is fully in contact with the soaking liquid, thereby improving the accuracy of the sensor measurement result.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, the utility model provides an embodiment of a real-time monitoring device, which is suitable for a plant rack 1. Several plant racks 1 are arranged in a vertical farm. A drainage port 2 is provided on the plant rack 1. A drainage channel 3 is provided downward on the bottom surface of the inner wall of the plant rack 1. The drainage channel 3 is inwardly retracted and extends in a slope toward the drainage port 2, so that after the substrate in the plant rack 1 is saturated and soaked, the overflowed soaking liquid can flow into the drainage channel 3.

[0021] Specifically, a converging channel 4 is opened between the drainage channel 3 and the drain outlet 2, and a converging port is formed at the connection between the converging channel 4 and the drainage channel 3. Similarly, the converging channel 4 extends in a slope toward the drain outlet 2, and the soaking liquid in the drainage channel 3 flows through the converging port and gathers in the converging channel 4. The width of the converging channel 4 is smaller than the diameter of the drain outlet 2, so that the soaking liquid can be completely discharged from the drain outlet 2 to avoid the soaking liquid remaining around the drain outlet 2. A sensor 6 is arranged in the converging channel 4, and the sensor 6 is a conductivity sensor for detecting the EC of the soaking liquid.

[0022] Furthermore, a baffle 5 with a top surface higher than the sensor 6 is provided at the edge of the drain outlet 2. The baffle 5 is fixedly installed at the end of the converging flow channel 4 to block the soaking liquid in the converging flow channel 4 so that the soaking liquid is gathered in the converging flow channel 4. As the soaking liquid converges, the liquid level in the converging flow channel 4 continues to rise until the soaking liquid submerges the probe of the sensor 6. After the conductivity sensor detects the EC of the soaking liquid, the liquid level exceeds the top surface height of the baffle 5. At this time, the soaking liquid passes over the baffle 5 and is discharged from the drain outlet 2.

[0023] The top surface height of the baffle plate 5 is lower than the top surface height of the drain outlet 2 , so as to prevent the soaking liquid from overflowing after passing over the baffle plate 5 , thereby causing liquid residue around the drain outlet 2 .

[0024] In this embodiment, after the substrate in the plant rack 1 is saturated and soaked, the overflowed soaking liquid flows outward, is drained through the drainage channel 3, and the soaking liquid enters the converging channel 4 and flows toward the drain port 2. The baffle 5 increases the drainage liquid level, and the soaking liquid cannot be discharged quickly, but is gathered in the converging channel 4. The gathered soaking liquid submerges the probe of the conductivity sensor, so that the probe is in full contact with the soaking liquid, and the soaking liquid is monitored in real time, thereby improving the accuracy of the measurement results of the sensor 6. The conductivity sensor detects the EC of the soaking liquid, and judges whether the fertilizer and water added during the planting process meet the growth needs of the plant based on the measured value, which is convenient for adjusting subsequent maintenance operations.

[0025] It is understandable that when the measurement method in the prior art is applied in a large-scale planting environment such as a vertical farm, it is necessary to sample and test the soaking liquid in several plant racks 1, which increases the labor cost and time cost, and is very time-consuming and labor-intensive. Although the sensor 6 is directly placed at the drain outlet to measure the overflowed soaking liquid, no manual sampling is required, but the overflowed soaking liquid will overflow, and the amount of water and fertilizer sprayed for indoor planting is small, and the overflowed soaking liquid is limited. The limited soaking liquid is difficult to completely submerge the sensor 6 on the basis of overflow, which makes it easy for the sensor 6 to measure inaccurately due to insufficient contact of the probe with the soaking liquid. The present application uses a baffle 5 to collect the limited soaking liquid in the converging channel 4, which can increase the contact between the sensor 6 probe and the soaking liquid.

[0026] In another embodiment, the sensor 6 is a pH sensor, which detects the pH value of the soaking liquid. The pH value is used to determine whether the fertilizer and water added during the planting process meet the growth requirements of the plants, so as to facilitate the adjustment of subsequent maintenance operations.

[0027] Working principle: After the substrate in the plant rack 1 is saturated and soaked, the overflowed soaking liquid flows outward, is drained through the drainage channel 3, enters the converging flow channel 4 and flows toward the drain port 2. The baffle 5 raises the drainage liquid level, and the soaking liquid cannot be discharged quickly, but is gathered in the converging flow channel 4. The gathered soaking liquid submerges the probe of the sensor 6, so that the probe is fully in contact with the soaking liquid, and the soaking liquid is monitored in real time.

[0028] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
