Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an oxygenation device for aquaculture ponds. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to finished aquatic product under artificial feeding and management. In a broader sense, aquaculture can also include aquatic resource enhancement. Pond aeration equipment is an indispensable part of aquaculture. It increases the oxygen content in the water, providing sufficient oxygen for aquatic organisms and ensuring their normal growth.

[0003] In the existing technology, there are many types of aerators used in aquaculture ponds. Common impeller aerators cannot oxygenate the bottom water of deeper ponds, and their oxygenation range is relatively limited. They cannot meet the oxygenation needs of aquaculture ponds of different depths, thus limiting the applicability of impeller aerators. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing technologies for aerators used in aquaculture ponds have many types, and the common impeller aerator cannot oxygenate the bottom water of deeper ponds, resulting in a limited oxygenation range and failing to meet the oxygenation needs of aquaculture ponds at different depths, thus limiting the applicability of impeller aerators.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an aeration device for aquaculture ponds, comprising: a connecting plate, a rotating rod rotatably connected to the center of the connecting plate, a waterproof motor fixedly connected to the top of the connecting plate, the output end of the waterproof motor fixedly connected to one end of the rotating rod, and a plurality of connecting rods fixedly connected in a circumferential array on the outer surface of the connecting plate, further comprising: A circular ring is fixedly connected to the outer surface of the connecting plate. Multiple connecting rods are fixedly connected in a circular array on the outer surface of the connecting plate. An arc-shaped block is fixedly connected to one end of each connecting rod. A fixing ring is fixedly connected to the outer surface of each connecting rod. A sleeve is fixedly connected to the inner wall of the fixing ring. A piston rod is slidably connected to the inside of the sleeve. An arc-shaped block is fixedly connected to one end of the piston rod. An air outlet pipe is fixedly connected to one side of the sleeve. A rubber hose is detachably connected to one end of the air outlet pipe. A conical air disc is detachably connected to one end of the rubber hose. An L-shaped air inlet pipe is fixedly connected to the outer surface of the sleeve. A spring is provided on the outer surface of the piston rod.

[0006] Preferably, the spring is fixedly connected to the fixed hanging ring and the arc-shaped block, and the outer surface of the L-shaped air intake pipe is fixedly connected to a protective cover by a bracket.

[0007] Preferably, a float is fixedly connected to one end of the connecting rod, and an impeller is fixedly connected to the other end of the rotating rod.

[0008] Preferably, the outer surface of the conical air plate has multiple air holes arranged in a circumferential array, a gravity ball is fixedly connected to the bottom of the conical air plate, and the L-shaped air inlet pipe, sleeve, air outlet pipe, rubber hose and conical air plate are connected to each other, and the multiple air holes are connected to the conical air plate.

[0009] Preferably, a one-way valve is fixedly connected to the inner wall of the rubber hose near the conical air disc, and a two-way valve is fixedly connected to the inner wall of the L-shaped air inlet pipe near the protective cover.

[0010] Preferably, the outer surface of the connecting rod is provided with a plurality of circular holes at equal intervals, and two movable lifting rings are slidably connected to the outer surface of the connecting rod. An adjusting rod is slidably connected to the top of the movable lifting rings, and one end of the adjusting rod is slidably connected to the inside of one of the circular holes.

[0011] Preferably, a second spring is provided on the outer surface of the adjusting rod, and the second spring is fixedly connected to the L-shaped plate and the adjusting rod respectively.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 0. This utility model, through the rotation of the rotating rod, can drive the ring, connecting rod two, and arc-shaped block one to rotate, causing arc-shaped block one to contact arc-shaped block two and apply a force, causing arc-shaped block two to drive the piston rod to move into the sleeve, increasing the air pressure inside the sleeve. Since the opening direction of one-way valve one is from the air outlet pipe towards the conical air plate, and the opening direction of one-way valve two is from the outside towards the sleeve, one-way valve one is open and one-way valve two is closed at this time, allowing gas to pass through the air outlet pipe, rubber hose, and conical air plate in sequence, generating bubbles, and evenly distributing the bubbles to the surroundings through the air holes, thus stimulating the water at the bottom of the pond. When the first and second arc-shaped blocks separate, the second arc-shaped block, under the restoring force of the first spring, can move the piston rod away from the sleeve. At this time, the air pressure inside the sleeve decreases, causing the first one-way valve to close and the second one-way valve to open, allowing outside air to enter the inside of the sleeve through the L-shaped air inlet pipe, preventing water from entering the rubber hose. This process is repeated, which can generate a large number of bubbles at the bottom of the pond. This allows for simultaneous aeration of the water at different depths above and below the pond, increasing the range of aeration and thus improving the applicability of the device.

[0013] 1. In this utility model, by manually pulling the adjusting rod upward, it disengages from the inside of the round hole, releasing the restriction on the L-shaped plate. Simultaneously, the second spring is stretched, allowing the movable lifting ring to slide on the first connecting rod. After adjusting to a suitable position, the adjusting rod is released, allowing it to be inserted into one of the round holes under the restoring force of the second spring. This achieves the restriction of the L-shaped plate and the movable lifting ring. In this way, not only can the rubber hose be supported by the movable lifting ring, but the depth of the conical air plate sinking can also be adjusted according to the length of the rubber hose. Thus, this device can be used for rubber hoses within a certain length range. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Examples, such as Figure 1-4 As shown, this utility model provides an aeration device for aquaculture ponds, including: a connecting plate 1, a rotating rod 102 rotatably connected to the center of the connecting plate 1, a waterproof motor 101 fixedly connected to the top of the connecting plate 1, the output end of the waterproof motor 101 fixedly connected to one end of the rotating rod 102, and multiple connecting rods 104 fixedly connected in a circumferential array on the outer surface of the connecting plate 1; and a ring 2 fixedly connected to the outer surface of the connecting plate 1, with multiple connecting rods 201 fixedly connected in a circumferential array on the outer surface of the connecting plate 1, and an arc-shaped block 202 fixedly connected to one end of each connecting rod 201. A fixed lifting ring 304 is fixedly connected to the outer surface of the connecting rod 104. A sleeve 305 is fixedly connected to the inner wall of the fixed lifting ring 304. A piston rod 306 is slidably connected inside the sleeve 305. An arc-shaped block 307 is fixedly connected to one end of the piston rod 306. An air outlet pipe 311 is fixedly connected to one side of the sleeve 305. A rubber hose 3 is detachably connected to one end of the air outlet pipe 311. A conical air disc 301 is detachably connected to one end of the rubber hose 3. An L-shaped air inlet pipe 309 is fixedly connected to the outer surface of the sleeve 305. A spring 308 is provided on the outer surface of the piston rod 306.

[0019] Furthermore, such as Figure 1-4 As shown, spring 308 is fixedly connected to fixed hanging ring 304 and arc-shaped block 307 respectively, and protective cover 310 is fixedly connected to the outer surface of L-shaped air intake pipe 309 through bracket.

[0020] Furthermore, such as Figure 1-4 As shown, a float 105 is fixedly connected to one end of the connecting rod 104, and an impeller 103 is fixedly connected to the other end of the rotating rod 102. The float 105 allows the device to float on the pond. By rotating the rod 102 to drive the impeller 103 to rotate, the pond water can be stirred, thus increasing oxygen levels.

[0021] Furthermore, such as Figure 1-4 As shown, the outer surface of the conical air plate 301 has multiple air holes 302 arranged in a circumferential array. A gravity ball 303 is fixedly connected to the bottom of the conical air plate 301. The L-shaped air inlet pipe 309, the sleeve 305, the air outlet pipe 311, the rubber hose 3 and the conical air plate 301 are connected to each other. The multiple air holes 302 are connected to the conical air plate 301. Through the above arrangement, the gas inside the sleeve 305 can pass through the air outlet pipe 311, the rubber hose 3, the conical air plate 301 and the air holes 302 in sequence to generate bubbles and oxygenate the bottom of the pond.

[0022] Furthermore, such as Figure 1-4As shown, a one-way valve is fixedly connected to the inner wall of the rubber hose 3 near the conical air plate 301, and a one-way valve is fixedly connected to the inner wall of the L-shaped air inlet pipe 309 near the protective cover 310. With the above arrangement, when the air pressure inside the sleeve 305 increases, the one-way valve opens and the one-way valve closes, allowing the gas to pass through the air outlet pipe 311, the rubber hose 3, and the conical air plate 301 in sequence, generating bubbles, and evenly generating bubbles around the sleeve through the air hole 302. When the air pressure inside the sleeve 305 decreases, the one-way valve closes and the one-way valve opens, allowing external gas to enter the interior of the sleeve 305 through the L-shaped air inlet pipe 309, preventing water from entering the rubber hose 3.

[0023] Furthermore, such as Figure 1-4 As shown, multiple circular holes 106 are equidistantly opened on the outer surface of the connecting rod 104. Two movable lifting rings 4 are slidably connected to the outer surface of the connecting rod 104. An adjusting rod 402 is slidably connected to the top of the movable lifting ring 4. One end of the adjusting rod 402 is slidably connected to the inside of one of the circular holes 106. The movable lifting ring 4 provides a certain support for the rubber hose 3. By pulling the adjusting rod 402 upward, it is disengaged from the inside of the circular hole 106, releasing the restriction on the L-shaped plate 401 and the movable lifting ring 4, allowing the movable lifting ring 4 to slide along the outer surface of the connecting rod 104.

[0024] Furthermore, such as Figure 1-4 As shown, a second spring 403 is provided on the outer surface of the adjusting rod 402. The second spring 403 is fixedly connected to the L-shaped plate 401 and the adjusting rod 402 respectively. By loosening the adjusting rod 402, it is inserted into one of the round holes 106 under the reset force of the second spring 403, thereby limiting the L-shaped plate 401 and the movable lifting ring 4.

[0025] Working Principle: In use, first select rubber hoses 3 of different lengths according to the depth of the aquaculture pond, connect the rubber hoses 3 to the air outlet pipe 311, and pass them through two movable rings 4. Then, install the conical air disc 301 at one end of the rubber hose 3. Place this device in the pond; under the action of the float 105, the device will float in the pond. Secure the device with ropes, causing the conical air disc 301 to sink to the bottom of the pond under the action of the gravity ball 303. This straightens the rubber hose 3, allowing it to slide along the inside of the movable rings 4. Then, the controller starts the waterproof motor 101, causing its output shaft to drive the rotating rod 102 to rotate, simultaneously driving the impeller 103 to rotate, thus purifying the pond. The water in the system is stirred and oxygenated. Simultaneously, the rotation of the rotating rod 102 drives the ring 2, connecting rod 201, and arc-shaped block 202 to rotate, causing arc-shaped block 202 to contact arc-shaped block 307 and apply a force. This causes arc-shaped block 307 to drive the piston rod 306 to move into the sleeve 305, increasing the air pressure inside the sleeve 305. Since the opening direction of one-way valve 1 is from the outlet pipe 311 towards the conical air plate 301, and the opening direction of one-way valve 2 is from the outside towards the sleeve 305, one-way valve 1 is open and one-way valve 2 is closed. This allows gas to pass through the outlet pipe 311, rubber hose 3, and conical air plate 301 in sequence, generating bubbles. These bubbles are then evenly distributed to the surrounding area through the air hole 302. This device aerates the water at the bottom of the pond. When arc-shaped block 202 separates from arc-shaped block 307, the resetting force of spring 308 causes arc-shaped block 307 to move piston rod 306 away from sleeve 305. At this time, the air pressure inside sleeve 305 decreases, causing one-way valve 1 to close and one-way valve 2 to open, allowing outside air to enter sleeve 305 through L-shaped air inlet pipe 309, preventing water from entering rubber hose 3. This process repeats, generating a large number of bubbles at the bottom of the pond. This allows for simultaneous aeration of the water at different depths, both above and below the pond, increasing the aeration range and thus improving the device's applicability. Pull the adjusting rod 402 upwards by hand to disengage it from the inside of the round hole 106, releasing the restriction on the L-shaped plate 401. Simultaneously, the second spring 403 is stretched. At this time, the movable lifting ring 4 can be pushed to slide on the connecting rod 104. Adjust it to a suitable position, then release the adjusting rod 402. Under the restoring force of the second spring 403, it is inserted into one of the round holes 106, thus limiting the L-shaped plate 401 and the movable lifting ring 4. In this way, not only can the rubber hose 3 be supported by the movable lifting ring 4, but the length of the rubber hose 3 can also be adjusted appropriately, and the depth of the conical air plate 301 sinking can be adjusted, so that this device can be used for rubber hoses 3 within a certain length range.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
