Description

Technical Field

[0001] The utility model relates to the technical field of oxygenators, in particular to a deep-water oxygenator for aquatic lobster farming. Background Art

[0002] In the process of aquaculture, aerators are usually used to oxygenate the fish pond, accelerate the convection of the water, increase the dissolved oxygen in the middle and lower layers of the water, promote the oxidative decomposition of organic matter, reduce the occurrence of diseases, and effectively prevent lobsters from "floating". At present, the type of aerator used in deep-water aquaculture is an inflatable aerator. The inflatable aerator is mainly composed of a motor, an air pump, a delivery pipe and an aeration stone. The air pump is driven by a motor to rotate and generate airflow, which delivers oxygen in the atmosphere into the water through the delivery pipe. The aeration stone is then responsible for releasing oxygen into the water through the micropores in the airflow.

[0003] Aeration stones are usually installed near the bottom of the fish pond for regular ventilation. However, the micropores in the aeration stones are completely exposed. When the aeration stones are not ventilated, lobsters will float silt and other impurities at the bottom of the pond into the micropores in the aeration stones. After the aeration stones have been used for a long time, the micropores in the aeration stones are very likely to be blocked by silt and other impurities, thereby affecting the normal flow of air. Utility Model Content

[0004] The utility model aims to solve the problem that the oxygenation stones used in the inflatable aerator in the prior art may be blocked by impurities such as silt, and proposes a deep-water oxygenation device for aquatic lobster farming.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A deep-water oxygenation device for aquatic lobster farming, comprising an oxygenation bubble stone, wherein the upper end surface of the oxygenation bubble stone is rotatably provided with a combined dust cover;

[0007] A driving mechanism is arranged on the lower end surface of the combined dust cover, and the driving mechanism includes a plurality of mutually symmetrical and parallel air cylinders and a plurality of telescopic rods. The plurality of telescopic rods are respectively lifted and installed in the plurality of air cylinders, and the top ends of the plurality of telescopic rods are all arranged on the lower end surface of the combined dust cover.

[0008] Preferably, the lower air inlets of the plurality of air cylinders and the air inlet of the oxygen-enhancing bubble stone are interconnected via a diverter.

[0009] Preferably, the diverter is composed of a main pipe, a plurality of diverter pipes and an air inlet joint, the air inlets of the plurality of diverter pipes are respectively fixedly connected and arranged on the periphery of the main pipe, the air outlet of the air inlet joint is fixedly connected to the main pipe, the terminal air outlets of the plurality of diverter pipes are respectively fixedly connected to the air inlets of the plurality of air cylinders, and the terminal air outlet of the main pipe is fixedly connected to the air inlet of the oxygen-enhancing bubble stone.

[0010] Preferably, a piston is fixedly connected to the lower end of the telescopic rod, and the piston is telescopically installed in the gas cylinder. A sealing ring is fixedly installed on the inner wall of the top end of the gas cylinder, and the sealing ring is arranged on the periphery of the telescopic rod.

[0011] Preferably, a sleeve is fixedly provided on the periphery of the oxygen-enhancing bubble stone, a through hole is provided at the lower end of the sleeve, the main pipe passes through the through hole, a plurality of circular grooves are symmetrically provided on both sides of the top of the sleeve, and a lower baffle is provided in the inner cavity at the lower end of the sleeve.

[0012] Preferably, the combined dust cover includes a plurality of fan blades, the head ends of the plurality of fan blades are arranged in a circle with the central axis of the sleeve as the center, a rubber sheet is connected between the head ends of the plurality of fan blades, and the two sides of the fan blades are rotatably installed in the two circular grooves through two corner blocks.

[0013] Compared with the prior art, the utility model provides a deep-water oxygenation device for aquatic lobster farming, which has the following beneficial effects:

[0014] The deep-water oxygenation device for aquatic lobster farming distributes the input oxygen to two air cylinders and an oxygenation bubble stone through a flow divider, and the inner cavity pressure gradually increases to lift the fan blades in the combined dust cover, and the micropores in the oxygenation bubble stone are responsible for releasing oxygen into the pool water through the airflow;

[0015] After the fan blades rotate upward at an angle, they still block the upper surface of the oxygen-enhancing bubble stone in the horizontal direction, thereby preventing the silt and impurities that sink vertically in the water from blocking the micropores in the oxygen-enhancing bubble stone. The silt and impurities that move upward at the lower end of the oxygen-enhancing bubble stone are also blocked by the sleeve and the lower baffle. In addition, the oxygen-enhancing bubble stone is used to drive the silt and impurities away from the upper surface of the oxygen-enhancing bubble stone under the thrust of the airflow discharged from the micropores, thereby ensuring that the micropores at the upper end of the oxygen-enhancing bubble stone will not be blocked by silt and impurities.

[0016] When the diverter stops inputting oxygen, the pressure in the two air cylinders and the oxygen-enhancing bubble stone gradually decreases, and they gradually sink under the deadweight of the fan blades and telescopic rod, as well as the elastic force of the rubber sheet, and finally cover the two fan blades in the combined dust cover on the upper end surface of the oxygen-enhancing bubble stone, effectively preventing impurities such as silt from entering the micropores in the oxygen-enhancing bubble stone, thereby correspondingly increasing the service life of the oxygen-enhancing bubble stone.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Reference Figure 1-3 A deep-water oxygenation device for aquatic lobster farming comprises a sleeve 1, a through hole 11 is arranged at the lower end of the sleeve 1, and a plurality of circular grooves 12 are symmetrically arranged on both sides of the top of the sleeve 1, and an oxygenation bubble stone 6 is coaxially slidably installed in the sleeve 1, the outer ring side wall of the oxygenation bubble stone 6 and the inner wall of the sleeve 1 are in contact with each other, and the upper surface of the sleeve 1 and the upper surface of the oxygenation bubble stone 6 are on the same horizontal plane, and a lower baffle plate 7 is coaxially fixed in the inner cavity of the lower end of the sleeve 1 by screws, and the sleeve 1 and the baffle plate 7 are used in combination to protect and seal the lower end and the periphery of the oxygenation bubble stone 6.

[0024] In this embodiment, the upper end surface of the oxygen-enhancing bubble stone 6 is rotatably provided with a combined dust cover 5, the combined dust cover 5 is circular as a whole, the inner ring part is connected to the upper end center axis position of the oxygen-enhancing bubble stone 6, and the outer ring can be rotated and lifted, and the combined dust cover 5 includes a plurality of blades 51, the head ends of the plurality of blades 51 are arranged in a circle with the center axis of the sleeve 1 as the center, and a rubber sheet 52 is sealed and fixedly connected between the head ends of the plurality of blades 51, and the two sides of the blades 51 are rotatably installed in the two circular grooves 12 through two corner blocks 53 respectively, the corner blocks 53 and the blades 51 are fixedly connected, and the corner blocks 53 and the circular grooves 12 are rotatably connected;

[0025] Reference Figure 1-3 It can be seen that the number of fan blades 51 in the combined dust cover 5 in the present application is specifically two. When the combined dust cover 5 is placed horizontally on the bottom of the pool water, if there is no external force pushing, the preset weight of the two fan blades 51 in the water is greater than the buoyancy in the water, and they will naturally droop and cover the upper surface of the oxygen-enhancing bubble stone 6, thereby effectively preventing impurities such as silt from entering the micropores in the oxygen-enhancing bubble stone 6.

[0026] In this embodiment, a driving mechanism is provided on the lower end surface of the dustproof plate 5, and the driving mechanism is mainly used to push the ends of the fan blades 51 in the combined dustproof cover 5 to rotate and lift up when the oxygen-enhancing bubble stone 6 releases oxygen, so as to ensure that the oxygen-enhancing bubble stone 6 can be used normally. The driving mechanism includes a plurality of mutually symmetrical and parallel air cylinders 3 and a plurality of telescopic rods 4. The specific number of the air cylinders 3 and the telescopic rods 4 is two. The two telescopic rods 4 are respectively lifted and installed in the two air cylinders 3, and the top ends of the two telescopic rods 4 are both arranged on the lower end surfaces of the ends of the two fan blades 51 in the combined dustproof cover 5;

[0027] A piston 41 is fixedly connected to the lower end of the telescopic rod 4. The outer diameter of the piston 41 is larger than the outer diameter of the telescopic rod 4. The piston 41 is telescopically installed in the gas cylinder 3. The outer diameter of the piston 41 is the same as the inner diameter of the gas cylinder 3, that is, the piston 41 and the gas cylinder 3 are sealed and connected. A sealing ring 31 is fixedly installed on the inner wall of the top end of the gas cylinder 3. The inner ring diameter of the sealing ring 31 is smaller than the inner diameter of the gas cylinder 3. The sealing ring 31 is closed and arranged on the periphery of the telescopic rod 4. The sealing ring 31 and the piston are used in conjunction with each other, one is for sealing, and the other is for limiting, so as to prevent the telescopic rod 4 from detaching upward from the gas cylinder 3.

[0028] In this embodiment, the lower air inlets of the two air cylinders 3 and the air inlet of the oxygen-enhancing bubble stone 6 are connected to each other through the diverter 2. The diverter 2 is composed of a main pipe 21, two diverter pipes 22 and an air inlet joint 23. The main pipe 21 slides through the through hole 11, and the main pipe 21 and the lower baffle 7 are in contact with each other. The air inlets of the plurality of diverter pipes 22 are respectively fixedly connected and arranged on the periphery of the main pipe 21. Figure 2The diverter 2 is provided with an air inlet and three air outlets. The air outlet of the air inlet joint 23 is fixedly connected to the main pipe 21, the end air outlets of the two diverter pipes 22 are fixedly connected to the air inlets of the two air cylinders 3 respectively, and the end air outlet of the main pipe 21 is fixedly connected to the air inlet of the oxygen-enhancing bubble stone 6, that is, the diverter 2 is mainly used to divide the pressure of the input airflow.

[0029] It should be noted that the fan blades 51 and the telescopic rod 4 are made of high-density metal or stone, which is much higher than the density of water. They are in a sinking state in the water and are used to sink and reset by their own weight. The rubber sheet 52 is made of highly elastic rubber. When the ends of the two fan blades 51 rotate and move, the head ends of the two fan blades 51 will compress the rubber sheet 52 to accumulate elastic potential energy, which can assist in the later reset of the two fan blades 51 and the two telescopic rods 4. That is, the rubber sheet 52 is used to block impurities such as silt and to assist in reset.

[0030] In the utility model, the air inlet of the air inlet joint 23 and the end of the delivery pipe in the inflatable aerator are connected to each other. The air pump in the inflatable aerator is driven by a motor to rotate and generate airflow, and oxygen in the atmosphere is sent to the diverter 2 in the water through the delivery pipe. The diverter 2 divides the input oxygen into three paths, which are respectively sent to two air cylinders 3 and the oxygen-enhancing bubble stone 6 for pressure division. The inner cavity pressure of the two air cylinders 3 and the oxygen-enhancing bubble stone 6 gradually increases to lift the fan blades 51 in the upper combined dust cover 5. In particular, the inner cavity pressure of the air cylinder 3 increases, which will lift the telescopic rod 4 at the upper end. The raised telescopic rod 4 is used to lift the fan blades 51 in the combined dust cover 5, and then the oxygen-enhancing bubble stone 6 is responsible for releasing oxygen into the water through the micropores thereon.

[0031] refer to Figure 1 After the fan blades 51 tilt upward, the fan blades 51 can still block the upper surface of the oxygen-enhancing bubble stone 6 in the horizontal direction, thereby preventing the silt and impurities that sink vertically in the water from blocking the micropores in the oxygen-enhancing bubble stone 6. The silt and impurities that move upward at the lower end of the oxygen-enhancing bubble stone 6 are also blocked by the sleeve 1 and the lower baffle 7. In addition, the oxygen-enhancing bubble stone 6 is used to drive the silt and impurities away from the upper surface of the oxygen-enhancing bubble stone 6 under the thrust of the airflow discharged from the micropores, thereby ensuring that the micropores at the upper end of the oxygen-enhancing bubble stone 6 will not be blocked by silt and impurities.

[0032] When the inflatable aerator is turned off, there is a lack of oxygen input in the inner cavities of the two air cylinders 3 and the oxygen-enhancing bubble stone 6, and the internal pressure gradually decreases. The deadweight of the fan blades 51 and the telescopic rod 4, as well as the rubber sheet 52 that accumulates elastic potential energy, will also assist the two fan blades 51 and the two telescopic rods 4 to reset and gradually sink, and finally cover the two fan blades 51 in the combined dust cover 5 on the upper end surface of the oxygen-enhancing bubble stone 6, effectively preventing impurities such as silt from entering the micropores in the oxygen-enhancing bubble stone 6, thereby correspondingly increasing the service life of the oxygen-enhancing bubble stone 6.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
