Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture devices, in particular to an aquaculture oxygenation device. BACKGROUND

[0002] Aquaculture equipment is an important technical support for the efficient development of modern aquaculture and the reform of the aquaculture industry structure, and its equipment types mainly include aquaculture equipment, aquaculture environment detection equipment, and aquaculture object sensing equipment. As an important basis for implementing aquaculture, aquaculture equipment covers production links such as temperature control, feeding, filtration, oxygenation, sterilization, pollution collection, grading, and catching. Among them, the aquaculture oxygenation equipment is the core means to control the dissolved oxygen of the aquaculture water, and the dissolved oxygen of the aquaculture water directly affects the yield and efficiency of the aquaculture industry. Therefore, the oxygenation equipment plays an important role in the field of aquaculture. Common oxygenation equipment types include aeration type and wave making type. The aeration type oxygenation equipment mainly applies to the deep layer of the water body for oxygenation work and cannot be moved, and its oxygenation area is limited. The wave making type oxygenation equipment mainly applies to the surface layer of the water body for oxygenation work, but cannot complete the oxygenation task of the deep layer of the water body. Obviously, the traditional oxygenation equipment is affected by the water environment and has a single application occasion.

The moving pair and the air injection equipment realize oxygenation treatment of the pool water at different depths, and the dissolved oxygen sensor detects the oxygen content of the pool water. When the oxygen content of the pool water is low, a prompt message is sent to the operator. Although the device improves the oxygenation effect, it cannot effectively realize the dissolved oxygen concentration regulation of any area in the aquaculture water body, and the oxygenation capacity is limited. At the same time, due to the limitation of its working purpose, the length of the slide rail must be adapted to the depth of the pool water, which will result in that the increase of the depth of the pool water will prolong the size of the slide rail, increase the cost and increase the operation and maintenance difficulty. Different pool water depths correspond to different lengths of the slide rail, which seriously limits the applicability of the device. Further, the device ignores the influence of impurities (such as floating algae and particulate matter) in the pool water environment on its working process. SUMMARY

[0028] In the description of the present embodiment, it should also be noted that the terms "set", "connected", "connected" should be understood broadly unless otherwise specified and limited.

[0029] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0030] Reference Figures 1 to 5 The present embodiment discloses an aquaculture oxygenation device, comprising a device main body 100, an external screw driving device 110, a floating assembly 200; the device main body 100 comprises: an expansion device 120, a gas pressure generating device 130; the external screw driving device 110 is symmetrically installed on the outside of the device main body 100 on both sides, and is provided with an aeration hole 111; the expansion device 120 directly contacts the external environment, and changes the volume of the expansion device 120 by adjusting the volume of the gas; the gas pressure generating device 130 is communicated with an air inlet pipe 131 at the front end, and the inlet of the air inlet pipe 131 is arranged on the floating assembly 200; the outlet of the gas pressure generating device 130 is also communicated with the aeration hole 111 of the external screw driving device 110.

[0031] As a further scheme of the present embodiment: the expansion device 120 comprises a high-pressure gas chamber 121, a compression cavity 122, a first valve 133, a second valve 134; the high-pressure gas chamber 121 is communicated with the outlet of the gas pressure generating device 130, and the first valve 133 is arranged at the communication position; the high-pressure gas chamber 121 is communicated with the aeration hole 111, and the second valve 134 is arranged at the communication position; the outer end of the compression cavity 122 directly contacts the external environment, and the inner end is communicated with the high-pressure gas chamber 121; a piston 123 is arranged in the compression cavity 122, and the piston 123 is in sealed sliding contact with the inner side wall of the compression cavity 122; a spring 124 is connected between the piston 123 and the compression cavity 122, and the spring 124 tends to move the piston 123 to the inner end of the compression cavity 122, helping the piston 123 to reset.

[0032] Further, the volume of the high-pressure air chamber 121 is related to the weight of the oxygenation device itself. The heavier the oxygenation device, the greater the gravity of the device itself, and the greater the required buoyancy. Increasing the volume of the high-pressure air chamber 121 can increase the displacement of the oxygenation device, and increasing the displacement can increase the buoyancy of the oxygenation device itself. Therefore, when the weight of the oxygenation device itself is determined, the volume of the high-pressure air chamber 121 can be determined in the design stage.

[0033] The air pressure generating device 130 in the embodiment uses existing technologies, such as a piston air pressure generator, a compressor, an air pump, etc.

[0034] In use, the device body 100 is located below the water surface, the float assembly 200 floats on the water surface, the inlet of the air inlet pipe 131 is arranged on the float assembly 200, and external air flows into the air pressure generating device 130 through the inlet of the air inlet pipe 131. Since the outlet of the air pressure generating device 130 is communicated with the expansion device 120 and the aeration hole 111, when the compressed gas in the air pressure generating device 130 enters the expansion device 120, it first enters the high-pressure gas chamber 121 and then flows into the compression cavity 122, and the volume of the gas in the expansion device 120 gradually increases. When the compressed gas does not enter the expansion device 120 but directly flows out of the aeration hole 111 to the external water body, the continuous oxygenation function of the oxygenation device can be realized. Therefore, in order to realize the conversion of the above functions, a first valve 133 is arranged at the communication position of the air pressure generating device 130 and the high-pressure gas chamber 121. When the first valve 133 is opened, the compressed gas mainly flows into the expansion device 120. When the first valve 133 is closed, the compressed gas directly flows into the aeration hole 111 through the pipeline to enter the outside. At the same time, in order to realize the reduction of the volume of the gas in the expansion device 120, an exhaust port is arranged to realize this function. The aeration hole 111 is used as the exhaust port of the high-pressure gas chamber 121, and a second valve 134 is arranged at the communication position of the high-pressure gas chamber 121 and the aeration hole 111. When the second valve 134 is opened, the gas in the expansion device 120 is discharged to the outside through the aeration hole 111. When the second valve 134 is closed, the gas in the expansion device 120 cannot flow to the outside. At this point, the working principle of the oxygenation device moving along the depth of the water body is as follows: when the second valve 134 is closed and the first valve 133 is opened, the volume of the gas in the expansion device 120 increases, the gas pushes the piston 123 in the compression cavity 122 to move to the outer end of the compression cavity 122, thereby increasing the volume of the expansion device 120, increasing the displacement of the oxygenation device, and making the buoyancy of the oxygenation device greater than its weight, so that the oxygenation device floats upward along the depth of the water body. When the oxygenation device floats to a certain height in the water environment, the first valve 133 is closed, and the gas in the expansion device 120 is slightly discharged through the second valve 134, so that the buoyancy of the oxygenation device is equal to its weight, and the oxygenation device is suspended in the water environment. When the first valve 133 is closed and the second valve 134 is continuously opened, the gas in the expansion device 120 is discharged through the aeration hole 111, the piston 123 in the compression cavity 122 is gradually reset under the pulling force of the spring 124, the volume of the expansion device 120 is reduced, the displacement of the oxygenation device is reduced, and the buoyancy of the oxygenation device is less than its weight, so that the oxygenation device sinks along the depth of the water body. When the oxygenation device needs to reach the working water area, in addition to using the expansion device 120 to make the oxygenation device float, sink and suspend along the depth of the water body, an external screw drive device 110 is also needed to provide driving force for the oxygenation device, so that the oxygenation device can move in a plane, such as linear motion or turning.Through the cooperation of the inflation device 120 and the external screw driving device 110, the oxygenation device can reach any position in the water body to perform the oxygenation work. When the oxygenation device works under the water surface, the device main body 100 is located under the water surface, and the float assembly 200 floats on the water surface. The inlet of the air inlet pipe 131 arranged on the float assembly 200 contacts the external gas, and the external gas is sucked in through the air inlet pipe 131 by the gas pressure generating device 130. At this time, the first valve 133 and the second valve 134 are closed, and the gas pressure generating device 130 directly discharges the compressed gas to the outside through the aeration hole 111 to perform the oxygenation work. At the same time, the external screw driving device 110 causes the change of the motion state of the water body in contact with it, so that the water body appears turbulent flow. The gas discharged from the aeration hole 111 contacts the turbulent flow, which on the one hand improves the breaking speed of the discharged gas bubbles, and on the other hand accelerates the diffusion of the oxygen-containing water body through the turbulent flow, so as to promote the dissolution of the gas in the water. Since the aeration hole 111 is in communication with the high-pressure gas chamber 121, the excess gas in the inflation device 120 can also be discharged through the aeration hole 111 to complete the oxygenation work of the oxygenation device, avoiding the waste of the gas sucked into the oxygenation device.

[0035] As a further scheme of the embodiment: the external screw driving device 110 includes a driver 112, and the output shaft of the driver 112 is drivingly connected with a propeller 113. The propeller 113 is provided with a plurality of aeration holes 111 on the blades.

[0036] Further, the blades of the propeller 113 are provided with a plurality of aeration holes 111 on the blade surfaces.

[0037] Further, the external screw driving device 110 is installed on the cantilevers on both sides of the device main body 100, and the two are connected through a rotary connecting device 114. The rotation axis of the external screw driving device 110 is perpendicular to the line connecting the symmetric points of the two external screw driving devices 110, and the rotation axis of the rotary connecting device 114 is parallel or coincides with the line connecting the symmetric points of the two external screw driving devices 110, so that the tip circle of the propeller 113 of the external screw driving device 110 can be parallel or perpendicular to the horizontal plane.

[0038] Through the technical solution, the embodiment can have two working states, including an oxygenation working state under water and an oxygenation working state on water. When the oxygenation device works under water, the external screw driving device 110 drives the rotation of the propeller 113 through the driver 112 to provide driving force for the planar motion of the oxygenation device. In a normal state, the tip circle of the propeller 113 is perpendicular to the horizontal plane. When the rotation speeds of the left and right propellers are consistent, the oxygenation device moves in a straight line. When the rotation speeds of the left and right propellers 113 have a large difference, the oxygenation device can turn. When the propeller 113 contacts with the water body, the rotational motion of the propeller 113 drives the water body in contact with it to move, so that the original motion state of the contact water body changes, and the water body appears turbulent flow. The water body after the motion state changes will contact the gas discharged from the plurality of aeration holes 111 on the blade surface of the propeller 113. With the bubbles entering the turbulent water body, the turbulent flow on one hand improves the breaking speed of the discharged bubbles, and on the other hand accelerates the diffusion of the oxygen-containing water body through the turbulent flow, thereby shortening the time for the gas to dissolve in the water.

[0039] When the oxygenation device works under water, according to the different water body environment, such as water flow environment, water temperature, water dissolved oxygen concentration, etc., the oxygenation device can adjust the parallel or perpendicular of the tip circle of the propeller 113 to the horizontal plane. When the tip circle of the propeller 113 is parallel to the horizontal plane, the direction of the turbulent flow caused by the propeller 113 is perpendicular to the horizontal plane, and the oxygen-containing water body in the turbulent flow also supplies oxygen to the depth direction of the aquaculture water body. At this time, since the tip circle of the propeller 113 is parallel to the horizontal plane, the rotation of the propeller 113 will provide driving force for the motion of the oxygenation device along the depth of the water body. The oxygenation device needs to adjust the second valve 134 to slightly exhaust or inflate, so as to reduce or increase the volume of the gas in the inflation device 120, so as to reduce or increase the buoyancy of the oxygenation device, so as to offset the influence of the upward or downward driving force. When the tip circle of the propeller 113 is perpendicular to the horizontal plane, the direction of the turbulent flow caused by the propeller 113 is parallel to the motion direction of the device main body, and the oxygen-containing water body in the turbulent flow also supplies oxygen along the motion direction of the turbulent flow, and the rotation of the propeller 113 will provide driving force for the planar motion of the oxygenation device. At the same time, by adjusting the power of the gas pressure generating device 130, the speed of aeration can be controlled; by adjusting the rotation speed of the aeration propeller 113, the strength and speed of the turbulent flow effect of the water body caused by the propeller 113 can be controlled.

[0040] When the oxygen increasing device works on the water surface, the oxygen increasing device floats to the water surface by the expansion device 120, and at this time, the principle of wave making is used to increase the oxygen in the surface water. In the underwater oxygen increasing working state, the tip circle of the propeller 113 is perpendicular to the horizontal plane, while in the oxygen increasing working state on the water surface, the tip circle of the propeller 113 is parallel to the horizontal plane. The rotation of the propeller 113 makes the spray splash in the air, increases the contact area of the water body and the air, and improves the oxygen content of the water body; when the high-oxygen water body splashes to the surrounding water body, not only the dissolved oxygen is brought into the water body, but also the air is brought below the water surface to generate a large number of bubbles, further promoting the mixing and contact of the air and the water body, so as to achieve the effect of rapidly increasing the oxygen in the surface water. At the same time, when the propeller 113 makes waves, the plurality of aeration holes 111 on the propeller 113 also come into contact with the surface water, and the gas discharged from the aeration holes 111 will enter the surface water. The surface water containing gas forms spray under the rotating action of the propeller 113, and the bubbles in the surface water break in the process of forming spray due to the change of the water body movement state, accelerating the process of bubble dissolution in the surface water, and further improving the oxygen content of the spray; when the spray splashes to the surrounding, the oxygen content of the surrounding water body will be rapidly improved and continuously diffused to the external water body.

[0041] As a further scheme of the embodiment: the external spiral driving device 110 is provided with an ultrasonic wave generating component 115, the ultrasonic wave generating component 115 adopts a ring shape, the diameter of the ring is greater than the rotating diameter of the propeller 113, the ultrasonic wave generating component 115 is rotationally connected with the two sides of the device main body 100 through the rotating connection device 114, the driver 112 is fixed on the ultrasonic wave generating component 115, the output shaft of the driver 112 is coaxial with the ultrasonic wave generating component 115, and the edge of the propeller blade of the propeller 113 is opposite to the inside of the ultrasonic wave generating component 115.

[0042] In use, the ultrasonic wave generating component 115 generates high-frequency sound waves around the ring body, and the water impurities, bubbles and water quality in the area where the sound waves are located will be affected. By using the cleaning effect of the ultrasonic wave generating component 115, on the one hand, the impurities clogging the aeration holes 111 of the propeller 113 in the water body are cleaned, so as to avoid the influence of the impurities on the exhaust function of the aeration holes 111, and on the other hand, the output shaft of the driver 112 is cleaned, so as to avoid the influence of the rotating movement of the propeller 113. At the same time, the bubbles discharged from the aeration holes 111 contact the high-frequency sound waves generated by the ultrasonic wave generating component 115, which accelerates the cracking of the bubbles, thereby shortening the process of gas dissolution in water. Therefore, by the power of the ultrasonic wave generating component 115, the cracking degree of the bubbles can be controlled, that is, the speed of gas dissolution in water can be controlled. Moreover, the ultrasonic wave has the effect of purifying water quality, which meets the concept of green and environmental protection.

[0043] As a further scheme of the embodiment, the air pressure generating device 130 is provided with a second one-way valve 135 at the position where the air pressure generating device 130 communicates with the aeration hole 111; the second one-way valve 135 allows the compressed gas discharged from the air pressure generating device 130 to be discharged from the aeration hole 111, and prevents the backflow of external air or water into the air pressure generating device 130.

[0044] As a further scheme of the embodiment, the device main body 100 further comprises an electrical cabin 140 for placing water-fearing electrical components, such as a battery, a motor of the air pressure generating device 130, a controller, a positioning device, etc.; the electrical cabin 140 is a sealed cavity, and the electrical cabin 140 communicates with the air pressure generating device 130 through a first one-way valve 132, which allows the gas to enter the electrical cabin 140 from the air pressure generating device 130; after the gas enters the electrical cabin 140, a positive air pressure is established in the electrical cabin 140, and the existence of the positive air pressure can prevent the water from the outside from seeping into the electrical cabin 140 through the gap, thereby effectively preventing the water from entering the electrical cabin 140 due to the failure of the sealing of the electrical cabin 140; the electrical cabin 140 further comprises an air pressure detection sensor, which can detect whether the air pressure value of the electrical cabin 140 decreases before each submersion work of the oxygenation device, so as to check whether the electrical cabin 140 has a gas leakage phenomenon.

[0045] As a further scheme of the embodiment, the floating assembly 200 comprises a solar panel 201, and the internal equipment of the electrical cabin 140 is connected with the solar panel 201 by wires, the wires are located in a wire tube 206, one end of the wire tube 206 is sealingly connected with the electrical cabin 140, and the other end of the wire tube 206 is sealingly connected with the solar panel 201; the wire tube 206 is located inside the air inlet pipe 131. By arranging the wire tube 206 inside the air inlet pipe 131, the direct contact between the external water and the wire tube 206 can be effectively prevented. Moreover, the air inlet pipe 131 inhales the gas, so that a negative air pressure is formed in the air inlet pipe 131; the wire tube 206 is sealingly connected with the electrical cabin 140, and the gas in the electrical cabin 140 fills the wire tube 206, so that a positive air pressure is formed in the wire tube 206; therefore, the wire tube 206 and the air inlet pipe 131 outside the wire tube 206 form a pressure difference, which further prevents the water from the outside from seeping into the wire tube 206.

[0046] As a further scheme of the embodiment, the float assembly 200 further comprises a float 202, the inlet of the air inlet pipe 131 is arranged on the upper surface of the float 202, an air filter screen 203 is arranged at the inlet of the air inlet pipe 131, a water blocking component 204 is arranged around the inlet of the air inlet pipe 131 on the upper surface of the float 202, and a rain shelter component 205 is arranged above the inlet of the air inlet pipe 131. The rain shelter component 205 completely covers and is higher than the air filter screen 203 and the water blocking component 204. The air filter screen 203 can block larger impurities in the air to prevent them from entering the inlet of the air inlet pipe 131. The water blocking component 204 can adopt a ring-shaped water blocking plate which can block the water on the upper surface of the float 202 from flowing into the inlet of the air inlet pipe 131. The rain shelter component 205 adopts a conical rain shelter on the top and a rain shelter support column on the bottom, which can block rainwater and prevent rainwater from flowing into the inlet of the air inlet pipe 131.

[0047] As a further scheme of the embodiment, the device further comprises a flow guide plate which is symmetrically arranged on the two sides of the device body 100 and is rotatably connected to the device body 100. The rotation axis of the rotatable connection device is parallel to the axis of the rotatable connection device 114. When the oxygenation device encounters an oncoming water flow, the flow guide plate can swing around the device body 100 with the fluctuation of the water flow, reducing the influence of the water flow on the oxygenation device and stabilizing the balance of the oxygenation device.

[0048] In summary, the adjustable parameters of the embodiment include the tip circle of the propeller 113 being parallel or perpendicular to the horizontal plane, the power of the air pressure generating device 130, the rotation speed of the propeller 113 (i.e. the power of the driver 112), and the power of the ultrasonic wave generating component 115. The above parameters can be adjusted according to different water environments, and the specific adjustment scheme can be set through experiments and empirical values, which will not be expanded here. To achieve the above adjustment process, it is foreseeable that the embodiment should also be provided with a dissolved oxygen detection sensor, a water flow speed detection sensor, and a temperature detection sensor to detect different water environments such as water body position (above the water surface, below the water surface), water flow environment, water temperature, water dissolved oxygen concentration, and water impurities. In addition, an obstacle detection sensor can also be provided to detect whether the oxygenation device will encounter obstacles during movement. If obstacles are encountered, the obstacle sensor and the controller can be used in cooperation to avoid obstacles.

[0049] The above only describes the preferred embodiment of the present application in detail, and does not limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
