Description

Technical Field

[0001] The utility model relates to the technical field of hydroponic pools, in particular to a cultivation pool for aquatic plants. Background Art

[0002] Aquatic plants refer to those plants that can grow in water. They have special structures and physiological characteristics adapted to the aquatic environment. When cultivating aquatic plants, a cultivation pool is required, which is a facility for cultivating and maintaining aquatic plants.

[0003] The cultivation pool usually consists of a cultivation pool, a floating board, a pipe and a water pump. The floating board is provided with through holes. When cultivating aquatic plants, usually clear water mixed with nutrient solution is injected into the cultivation pool, and then the aquatic plants are placed into the through holes of the floating board, and the floating board is placed on the top of the cultivation pool. The water pump is started to pump the clear water inside the cultivation pool out through the pipe and then transported back into the cultivation pool from one side of the cultivation pool, so that the clear water inside the cultivation pool can flow and mix with the air, or the clear water inside the cultivation pool is pumped out by the water pump and the pipe, and dripped into the cultivation pool in the form of water droplets from the water outlet end of the pipe, so that the clear water inside the cultivation pool splashes to mix with the air, thereby dissolving the oxygen in the air into the clear water.

[0004] However, through the above two methods of mixing clear water with air, less air is mixed, so that the effect of dissolving oxygen in clear water is poor, and it is not convenient to increase the oxygen content in the clear water. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a cultivation pool for aquatic plants, aiming to improve the problem that in the prior art, through the above two methods of mixing clear water with air, less air is mixed, so that the effect of dissolving oxygen in clear water is poor, and it is not convenient to increase the oxygen content in the clear water.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: A cultivation pool for aquatic plants, comprising:

[0007] A cultivation pool, one side of the cultivation pool is communicated with a pipe, and the other end of the pipe passes through the bottom wall of the cultivation pool and extends into the cultivation pool, so that the water inside the cultivation pool can circulate;

[0008] A funnel, fixedly connected to one side of the cultivation pool, the bottom of the funnel is communicated with a connecting pipe, and one end of the connecting pipe is communicated with the end of the pipe close to the cultivation pool;

[0009] A water pump, communicated with the outside of the pipe.

[0010] As a further description of the above technical solution:

[0011] Further included is a baffle fixedly connected to one side of the inner side wall of the cultivation pond close to the pipeline.

[0012] As a further description of the above technical solution:

[0013] A throat tube is installed at the water outlet end of the pipeline. The diameter of the throat tube is smaller than that of the pipeline, and one end of the connecting pipe is connected to the upper side of the throat tube.

[0014] As a further description of the above technical solution:

[0015] A floating plate is installed at the top of the cultivation pond. A plurality of through holes are provided on the floating plate for placing aquatic plants.

[0016] As a further description of the above technical solution:

[0017] The baffle is arranged in a V-shaped structure.

[0018] As a further description of the above technical solution:

[0019] Convex blocks are fixedly connected to the bottom of the cultivation pond.

[0020] The utility model has the following beneficial effects:

[0021] In the utility model, when the water pump is started, the clear water inside the cultivation pond enters the pipeline and flows inside the pipeline. When the clear water flows into the throat tube, the flow rate of the clear water reaches the maximum value and the pressure drops to the lowest. At this time, the throat tube will generate suction to suck the external air into the pipeline through the funnel and the connecting pipe to be mixed with the clear water, so as to increase the oxygen content in the clear water.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Referring to Figures 1-3 , an embodiment provided by the present invention: an aquatic plant cultivation pool, including a cultivation pool 1, a groove is opened at the top of the cultivation pool 1, a floating plate 4 is placed inside the groove, and a plurality of through holes are opened at the top of the floating plate 4.

[0029] Inject clear water mixed with nutrient solution into the cultivation pool 1, and place aquatic plants in the through holes of the floating plate 4. Place the floating plate 4 into the groove at the top of the cultivation pool 1 so that the root systems of the aquatic plants can extend into the clear water, enabling the root systems of the aquatic plants to absorb the nutrients in the clear water.

[0030] One side of the cultivation pool 1 is connected to a pipeline 2. One end of the pipeline 2 is connected to the bottom of the cultivation pool 1. The water inlet end of the pipeline 2 is flush with the bottom of the cultivation pool 1. A water pump 8 is connected to one end of the pipeline 2 near the bottom of the cultivation pool 1. A throat tube is installed at the water outlet end of the pipeline 2. The diameter of the throat tube is smaller than that of the pipeline 2. The specific installation method of the throat tube is: two conical tubes are butted with their smaller-diameter ends and welded together to form a connected cylindrical structure. A connecting pipe 7 is connected to the upper side of the narrowest part of the throat tube. One end of the connecting pipe 7 is connected to a funnel 3. As Figure 3 shown, the funnel 3 is fixedly connected to one side of the cultivation pool 1.

[0031] Start the water pump 8 to make the clear water inside the cultivation pool 1 enter the pipeline 2. The clear water will flow towards the throat tube. At this time, the flow rate of the clear water gradually increases, and the pressure also gradually decreases. When the clear water flows through the throat tube, the flow rate of the clear water reaches the maximum value and the pressure drop in the throat tube also reaches the lowest. At this time, the low pressure inside the throat tube causes the funnel 3 and the connecting pipe 7 to generate suction to transport air into the pipeline 2 to mix with the clear water, increasing the oxygen content in the clear water.

[0032] When it is necessary to add nutrient solution to the clear water, pour the nutrient solution into the funnel 3. Because the pressure inside the throat tube is relatively low when the clear water is flowing, the connecting pipe 7 will generate suction, sucking all the nutrient solution inside the funnel 3 into the pipeline 2, so as to avoid nutrient solution residue inside the funnel 3 and spraying it into the cultivation pool 1 together with the clear water from the water outlet end of the pipeline 2. And compared with directly adding the nutrient solution into the clear water, by adding the nutrient solution in the above way, it is not necessary to stir the clear water after adding the nutrient solution into the clear water.

[0033] On one side of the inner wall of the cultivation pool 1 close to the pipeline 2, a baffle 5 is fixedly connected. The baffle 5 is arranged in a V-shaped structure. After the clear water flows out of the pipeline 2, it will impact on the baffle 5, enabling the clear water to generate a vortex, increasing the contact area and contact time between the clear water and the air, and thus facilitating the dissolution of oxygen into the clear water.

[0034] A plurality of bumps 6 are fixedly connected to the bottom of the cultivation pool 1. When the clear water inside the cultivation pool 1 flows, the bumps 6 will disrupt the flow of the clear water, causing the clear water to generate turbulence, increasing the contact area and contact duration between the clear water and the air, and enabling more air to be mixed into the clear water.

[0035] Pour the clear water mixed with nutrient solution into the cultivation pool 1. Then place the floating plate 4 on the top of the cultivation pool 1, and put the aquatic plants into the through holes, so that the roots of the aquatic plants extend into the clear water. Start the water pump 8 to make the clear water inside the cultivation pool 1 enter the pipeline 2. When the clear water flows into the throat pipe, the flow rate of the clear water reaches the maximum value and the pressure drops to the lowest. At this time, the low pressure inside the throat pipe will cause the funnel 3 and the connecting pipe 7 to generate suction, sucking the external air into the pipeline 2 through the connecting pipe 7 to be mixed with the clear water. When the clear water flows out of the pipeline 2 and enters the cultivation pool 1, it will impact on the surface of the baffle 5 to generate a vortex, increasing the contact area between the clear water and the air and increasing the oxygen content in the clear water.

[0036] Through the above method, the clear water inside the cultivation pool 1 can flow. During the flow of the clear water inside the cultivation pool 1, the bumps 6 will disrupt the flow of the clear water, causing the clear water inside the cultivation pool 1 to generate turbulence, increasing the contact area and contact time between the clear water and the air, and facilitating the dissolution of oxygen in the air into the clear water.

[0037] When it is necessary to add nutrient solution to the clear water again, pour the nutrient solution into the funnel 3, and then transport the nutrient solution inside the funnel 3 to the pipeline 2 through the connecting pipe 7, and enter the cultivation pool 1 together with the clear water inside the pipeline 2.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
