Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to an oxygenation device for aquaculture. Background Technology
[0002] In the field of aquaculture, the dissolved oxygen content in the water is one of the key factors affecting the growth, survival and health of farmed organisms. Farmed organisms such as fish and shrimp need to consume dissolved oxygen in the water during respiration. With the continuous increase in stocking density, the demand for dissolved oxygen by farmed organisms increases sharply. Therefore, in order to ensure the smooth operation of aquaculture and improve the yield and quality, it is necessary to use aquaculture oxygenation devices to increase the dissolved oxygen content in the water.
[0003] Currently, the most common oxygenation devices on the market are aerators. Aerators throw water into the air to form a water curtain, allowing water and air to come into full contact, increasing dissolved oxygen, constantly renewing the water surface, and improving dissolved oxygen efficiency. Aerators can meet the oxygenation needs of aquaculture to a certain extent.
[0004] However, most existing aeration devices lack flexible filtration functions. In some aquaculture areas with fewer impurities or algae, the filter structure such as the filter screen near the aerator's intake will significantly obstruct the water flow when the aerator is working, increasing the water intake pressure. This causes the aerator's spray height to decrease, resulting in insufficient mixing of the sprayed water with oxygen in the air, thus affecting the aeration effect. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0026] Example 1
[0027] Reference Figures 1-5 This is the first embodiment of the present invention, which provides an aeration device for aquaculture, including an aerator body 1. A floating mechanism 2 for buoyancy of the aerator body 1 and a filtration mechanism 3 for filtration are provided on the outer side of the aerator body 1. The filtration mechanism 3 includes a mounting frame 31, a sliding groove 32 inside the mounting frame 31, a filter plate 33 inside the sliding groove 32, a connecting groove 34 evenly distributed on the middle end face of the mounting frame 31, a positioning groove 35 evenly distributed inside the sliding groove 32, and a limit assembly inside the mounting frame 31. Component 36, the outer side of the aerator body 1 is provided with a connecting component 4 for connecting the aerator body 1 and the floating mechanism 2. The limiting component 36 includes an annular plate 361. The connecting groove 34 is slidably connected to a limiting cylinder 362. The limiting cylinder 362 is slidably connected to a positioning post 363. The end face of the positioning post 363 and the inner wall of the limiting cylinder 362 are fixedly connected to a compression spring 364. The outer side of the positioning post 363 is circumferentially arranged with a limiting rod 365. The inner wall of the limiting cylinder 362 is circumferentially arranged with a limiting groove 366.
[0028] Specifically, the limiting cylinder 362 is fixedly connected inside the filter plate 33, the limiting rod 365 is slidably connected inside the limiting groove 366, the limiting rod 365 is slidably connected inside the limiting cylinder 362, and the end of the limiting rod 365 away from the positioning post 363 is fixedly connected to the end face of the annular plate 361. The floating mechanism 2 includes a float plate 21 fixedly connected to the outside of the mounting frame 31, and traction holes 22 are evenly opened on the outer periphery of the float plate 21.
[0029] The mounting frame 31 has a conical structure. The aerator body 1 is located in the center of the mounting frame 31. The filter plate 33 is slidably connected to the inside of the slide groove 32. There are at least four filter plates 33, all of which are slidably connected to the inside of the slide groove 32. The end of the positioning column 363 away from the limiting cylinder 362 will abut against the inside of the positioning groove 35 under the action of the compression spring 364. The limiting rod 365 is slidably connected to the inside of the limiting groove 366. When the annular plate 361 is rotated, the limiting rod 365 can synchronously drive the limiting cylinder 362 to move through the limiting groove 366.
[0030] When using this aeration device in aquaculture areas with few impurities or algae, first pull the annular plate 361 away from the mounting frame 31. During this process, the movement of the annular plate 361 causes the positioning pin 363 to disengage from the positioning groove 35 via the limiting rod 365. The limiting rod 365 slides inside the limiting groove 366, compressing the compression spring 364. At this time, rotating the annular plate 361 causes the limiting cylinder 362 to move synchronously inside the connecting groove 34 through the cooperation of the limiting rod 365 and the limiting groove 366. The connecting groove 34 can limit the movement of the limiting cylinder 362. Therefore, when the annular plate 361 is pulled, the limiting cylinder 362 will not move vertically. Since the limiting cylinder 362 is fixedly connected inside the filter plate 33, when the limiting cylinder 362 moves inside the connecting groove 34, it will synchronously drive the filter plate 33 to move, so that the filter plate 33 moves through the sliding groove 32 into the mounting bracket 31. When the filter plate 33 moves into place, the annular plate 361 is released. Under the action of the compression spring 364, the positioning pin 363 will be driven to engage inside the positioning groove 35. To limit the position of the filter plate 33, a traction rope is connected to the traction hole 22. The traction rope and traction hole 22 are used to fix the position of the device on the water surface and prevent it from drifting away due to water fluctuations. The device is placed in the water, and the float plate 21 makes the upper part of the aerator body 1 float on the water surface. The power is turned on and the aerator body 1 is started. At this time, the filter plate 33 is in the retracted state and the mounting bracket 31 is in the open state. Water can directly enter the water intake range of the aerator body 1 from the open position of the mounting bracket 31. Without the obstruction of the filter plate 33, the aerator body 1 can be reduced in size. The suction pressure during operation increases the spray height of the aerator body 1, allowing the water sprayed from the aerator body 1 to mix more fully with oxygen in the air, thus effectively improving the oxygenation effect. When there are many impurities or algae in the aquaculture area, the annular plate 361 can be rotated in the reverse direction to open the filter plate 33. The mounting frame 31 and the filter plate 33 form a barrier. At this time, water can only enter the suction range of the aerator body 1 through the filter plate 33, thereby filtering impurities or algae in the aquaculture area and preventing damage to the aerator body 1.
[0031] Example 2
[0032] Reference Figures 1-8This is the second embodiment of the present invention. Based on the previous embodiment, the difference is that it provides an aeration device for aquaculture. The connecting component 4 includes a connecting plate 41 fixedly connected to the outside of the aerator body 1. The outer periphery of the connecting plate 41 is evenly provided with snap-fit grooves 42. The inner side of the mounting bracket 31 is evenly provided with mounting grooves 43. Limiting plates 44 are slidably connected inside each mounting groove 43. A connecting block 45 is fixedly connected to one end of each limiting plate 44 near the connecting plate 41, and the limiting plate 44 is further away from the connecting block 45. One end of each of the 5 is fixedly connected to a first spring 46. The middle end face of the mounting frame 31 is fixedly connected to a limiting post 47 in a circular array. The outer side of the limiting post 47 is slidably connected to a pressure plate 48. The end of the pressure plate 48 near the mounting frame 31 is fixedly connected to a pressure ring 49. The end face of the pressure plate 48 and the end face of the mounting frame 31 are evenly fixedly connected to a second spring 411. The middle end of the mounting frame 31 near the pressure plate 48 is evenly fixedly connected to a handle 412. The middle end of the mounting frame 31 near the pressure plate 48 is provided with an annular groove 413.
[0033] Specifically, the connecting blocks 45 are all slidably connected inside the mounting groove 43, the end of the first spring 46 away from the limiting plate 44 is fixedly connected inside the mounting groove 43, the pressure ring 49 is slidably connected inside the annular groove 413, the second spring 411 is sleeved on the outside of the limiting post 47, and the annular groove 413 and the mounting groove 43 are interconnected.
[0034] The connecting block 45 is angled at the end away from the limiting plate 44, and the connecting block 45 is compatible with the snap-fit groove 42. The first spring 46 is set inside the mounting groove 43. The pressure plate 48 can only move along the limiting post 47. The handle 412 is set outside the pressure plate 48. The pressure ring 49 is slidably connected inside the annular groove 413, and the end of the pressure ring 49 away from the pressure plate 48 abuts against the angled surface of the connecting block 45.
[0035] When in use, if it is necessary to disassemble and maintain the aerator body 1 and the floating mechanism 2, or to clean the surface of the filter plate 33, the pressure plate 48 can be pressed towards the connecting plate 41. The second spring 411 is compressed under force, and the pressure plate 48 drives the pressure ring 49 to slide into the interior of the annular groove 413, and squeezes the beveled surface of the connecting block 45, so that the connecting block 45 slides inside the mounting groove 43. The limiting plate 44 slides synchronously, compressing the first spring 46, so that the end of the connecting block 45 is disengaged from the interior of the snap-fit groove 42, and the aerator body 1 can be separated from the floating mechanism 2. During installation, the above operation is reversed. After separation, the aerator body 1 is no longer obstructed by the floating mechanism 2 and the filter mechanism 3, which makes it easier to clean and maintain the aerator body 1, and also makes it easier to clean the filter plate 33 in the filter mechanism 3. At the same time, with this setting, it is not necessary to use wrenches or other tools to disassemble it, and only one person is needed to operate it, thereby improving the efficiency and cost of maintenance.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
