Description

Technical Field

[0001] The invention relates to the field of aquaculture and water quality monitoring, and in particular to a simple device for measuring dissolved oxygen in a simulated rice-fish symbiotic floating plate mode. Background Art

[0002] The "rice-fish symbiotic floating board model" is a new type of three-dimensional rice planting model, which can achieve the purpose of "planting rice on water + raising fish underwater" and realize the effect of "one water, two uses, fish and rice symbiosis".

[0003] This model also has several key technical difficulties, one of which is the lack of dissolved oxygen. In order to further improve the efficiency and ecological benefits of fish farming, it is necessary to conduct real-time dissolved oxygen measurement in the rice-fish symbiosis system.

[0004] The current monitoring methods mainly rely on manual sampling and laboratory analysis, which not only consumes a lot of time and energy, but also makes it difficult to achieve real-time monitoring. Therefore, in the application of the rice-fish symbiotic floating plate model, an efficient, accurate and economical dissolved oxygen measurement device is urgently needed to meet the special needs of the rice-fish symbiotic breeding system. Summary of the invention

[0005] The purpose of the present invention is to provide a simple device for simulating dissolved oxygen measurement in a rice-fish symbiosis floating plate mode, which is not only low-cost and easy to operate, but also suitable for rice-fish symbiosis systems of various sizes.

[0006] To this end, the present invention provides a simple device for measuring dissolved oxygen in a floating plate mode simulating rice-fish symbiosis, comprising: a transparent water tank, a rice floating plate planting unit, and an aeration pipe. Fish are raised underwater in the transparent water tank to simulate the water environment of rice-fish symbiosis. An air pump is provided outside the transparent water tank, and an aeration pipe is provided at the bottom of the water tank. The air pump is connected to an air inlet of the pipe so that water can circulate in the water tank. A dissolved oxygen meter is installed outside the transparent water tank, and a dissolved oxygen probe is connected to the dissolved oxygen meter through a cable to measure the dissolved oxygen in water.

[0007] The device is low-cost and easy to operate, and can measure the level of dissolved oxygen in the rice-fish symbiosis system in real time to maintain the dissolved oxygen level in the water body within an appropriate range.

[0008] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0012] Combined with reference Figures 1 to 3 The simple device for measuring dissolved oxygen in a floating plate mode simulating rice-fish symbiosis of the present invention comprises: a transparent water tank 1, a dissolved oxygen meter 2 and a power module 3.

[0013] An appropriate amount of rice is planted in the transparent water tank 1, and a certain number of fish are put in. The rice and fish grow together to form a rice-fish symbiotic environment. The dissolved oxygen meter is connected to the probe 5 through a cable 4, and the other end is connected to the power module 3. By placing the probe 5 in the rice-fish symbiotic water body, the dissolved oxygen is measured.

[0014] An aeration pipe 11 is installed at the bottom of the transparent water tank. The air inlet of the aeration pipe 11 is connected to the air outlet of the air pump 12. The air inlet pipe is provided with evenly spaced small holes 13 to ensure that the bubbles are evenly distributed in the water body so that the water can circulate in the water tank.

[0015] Slide rails 6 and up and down regulators 7 are respectively installed inside and outside the transparent water tank. A self-weight slider 8 is installed on the slide rail 6. The self-weight slider 8 and the up and down regulator 7 are connected by a cable 4. One end of the cable 4 is constrained on the cross bar 9, and the probe 5 is electrically connected to realize the lifting and lowering movement through the up and down regulator 7.

[0016] The cable 4 is used as both an electric cable and a cable. By operating the up and down adjuster 7, the cable 4 can be pulled downward without affecting signal transmission.

[0017] A fixer 10 is provided on the crossbar 9 , and the fixer 10 can be used to fix the probe 5 . The crossbar 9 can be a telescopic rod or a multi-folding rod to reach different horizontal positions in the transparent water tank 1 .

[0018] By moving the upper and lower regulators 7 up and down, the cross bar 9 is driven to move up and down. The lifting of the cross bar 9 will cause the probe 5 to move up and down, so that the probe can be at different heights in the water tank, and the probe 5 can be stably maintained in a horizontal position through the cross bar 9 to perform real-time measurement of dissolved oxygen.

[0019] like Figure 4 As shown, when the dissolved oxygen level measured by the dissolved oxygen meter is lower than the lower limit of the set threshold interval, the air pump 12 is turned on, and when the dissolved oxygen exceeds the upper limit of the set threshold interval, the air pump 12 is stopped, thereby achieving closed-loop control of the dissolved oxygen.

[0020] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
