Description

Technical Field

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding and management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive farming, intensive farming and high-density intensive farming.

[0003] Aquaculture provides delicious seafood to many people, but farmers need to do a lot of work to provide delicious seafood to customers. One of the tasks is to supply oxygen to the breeding ponds. At the same time, in the dry season or when there is insufficient rain, water needs to be added to the breeding ponds regularly. Replenishing water can ensure that the water body will not dry up and maintain the ecological balance.

[0004] In the prior art, when oxygenating the breeding pond, a water pump is started, and the water pump inputs water into a central tube, and the water in the central tube is sprayed to the outside, and the water at the bottom of the breeding pond is pumped to the upper end of the water surface to dissolve the external oxygen. Then, when the water falls on the surface of the breeding pond, it stirs up water splashes, so that the contact area between the external oxygen and the water surface of the breeding pond is increased, and the oxygenation operation is completed.

[0005] However, the existing device has the following shortcomings during use: The existing device is not convenient for supplying oxygen while filling water into the culture pond, which reduces the scope of use of the device.

[0006] In the existing device, the position of the nozzle is fixed, which makes the spraying range of the nozzle small and reduces the dissolution efficiency of oxygen.

[0015] Preferably, a rotating rod is connected to one side of the mounting frame via a bearing, one end of the rotating rod movably penetrates the filter screen and is fixedly connected to a scraper, and a spiral fan blade is fixedly sleeved on the outer surface of the rotating rod.

[0018] An oxygenation method for an aquaculture oxygenation device comprises the following steps: Step 1: Start the second drive motor through the PLC controller to make the two bidirectional threaded rods rotate synchronously. The two bidirectional threaded rods drive the four first moving blocks to move relative to each other. With the cooperation of the first U-shaped block, the second U-shaped block and the connecting rod, the lifting plate and the four support rods rise, and the conveying hard pipe is lifted to the required height.

[0019] Step 2: Start the water pump through the PLC controller. The water pump pumps water into the filter cartridge. The filter screen filters impurities. At the same time, the water in the filter cartridge drives the spiral fan blades to rotate, and then drives the scraper to scrape the filter screen. At the same time, the solenoid valves on the flushing pipe and the sewage pipe are opened through the PLC controller, and then water is poured into the filter cartridge through the flushing pipe to flush the filter screen and the filter cartridge, so that the impurities can be discharged through the sewage pipe.

[0020] Step 3: The water pump generates vibration during operation, and the silencer sponge absorbs the noise. At the same time, the vibration causes the mounting plate to move downward. At this time, the hydraulic damping rod is squeezed. At the same time, the third U-shaped block and the second connecting rod drive the second moving block to move. The shock-absorbing spring is squeezed by the second moving block and begins to shrink. The elastic potential energy of the shock-absorbing spring and the damping effect of the hydraulic damping rod jointly reduce the vibration force.

[0021] Step 4: The water pump draws water into the filter cartridge, and then enters the connecting hard pipe after passing through the first telescopic tube, the second telescopic tube and the third telescopic tube, and then is sprayed out through the delivery hard pipe and the spray hole, so that the water dissolves the external oxygen and falls on the surface of the breeding pond. Then, the first drive motor is started through the PLC controller, thereby driving the delivery hard pipe to move and rotate at the same time.

[0022] Step 5: When the moving seat moves to contact one of the sensors, one of the sensors transmits a signal to the PLC controller. After receiving the signal, the PLC controller starts the first drive motor to reverse, causing the moving seat to move in the opposite direction. When the moving seat moves in the opposite direction and contacts another sensor, similarly, the PLC controller starts the first drive motor to rotate forward, allowing the conveying tube to reciprocate.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets an oxygenation mechanism, and with the cooperation of a fixed plate, a limit rod, a one-way threaded rod, a movable seat, a connecting hard pipe, a conveying hard pipe, a spraying hole, a fixed block, a rack, a gear, a first drive motor, a sensor, and a PLC controller, the purpose of reciprocating and rotating the conveying hard pipe is achieved, thereby solving the problem of a small spraying range, improving the dissolution efficiency of oxygen, and facilitating the oxygenation operation while filling water into the aquaculture pond.

[0024] 2. The present invention provides a noise reduction mechanism, and the silencer sponge absorbs noise. At the same time, under the elastic potential energy of the shock-absorbing spring and the damping action of the hydraulic damping rod, it has a buffering and shock-absorbing effect, effectively reducing noise. At the same time, it reduces vibration and effectively avoids the impact on the device and the surrounding environment, thereby improving the stability and service life of the device.

[0025] 3. By setting up the adjustment mechanism and starting the second drive motor through the PLC controller, under the action of the linkage structure, the lifting plate drives the four support rods to move upward, thereby driving the conveying hard pipe to move upward, which has the effect of adjusting the height of the conveying hard pipe, thereby expanding the spraying range and further improving the dissolution efficiency of oxygen.

When the lifting plate 207 moves upward, it drives the supporting rods 213 to move upward, and then drives the conveying hard pipe 506 to move upward, which makes it easy to adjust the height of the conveying hard pipe 506 and improves the spraying range.

[0033] like Figure 4 , Figure 6 and Figure 7As shown, the noise reduction shell 401 is bolted to the top of the support plate 3, the PLC controller 513 is installed on one side of the noise reduction shell 401, and a noise-reducing sponge 402 is arranged on the inner side of the noise reduction shell 401.

Under the action of the hydraulic damping rod 403, the second movable block 408, the third U-shaped block 409 and the second connecting rod 410, a buffering and shock-absorbing effect is achieved, thereby improving the stability of the device.

[0034] like Figure 4 and Figure 6 As shown, the filter cartridge 601 is fixedly connected to one side of the noise reduction shell 401, one end of the filter cartridge 601 is fixedly connected to a first telescopic tube 602, and the other end of the filter cartridge 601 is fixedly connected to a water pump 603. The end of the first telescopic tube 602 away from the filter cartridge 601 is movable and passes through the noise reduction shell 401 and the silencer sponge 402 and is connected to the input end of the water pump 7. A mounting frame 604 and a filter screen 605 are fixedly connected inside the filter cartridge 601. By setting the water pump 603, it is convenient to connect the water pipe to an external water source. The filter screen 605 is set to filter and remove impurities from the water to avoid impurities blocking the pipeline.

[0035] like Figure 4 As shown, one side of the mounting frame 604 is connected to a rotating rod 606 via a bearing, one end of the rotating rod 606 is movably inserted into the filter screen 605 and is fixedly connected to a scraper 607, and a spiral blade 608 is fixedly sleeved on the outer surface of the rotating rod 606. When the water pump 7 is working, the power of the water flow can drive the spiral blade 608 to rotate, which is convenient for driving the scraper 607 to rotate and scrape the filter screen 605, so as to prevent impurities from blocking the filter screen 605 and affecting the use of the device.

[0036] like Figure 4As shown, the outer surface of the filter cartridge 601 is fixedly connected with a flushing pipe 609 and a drain pipe 610, and both the flushing pipe 609 and the drain pipe 610 are installed with an electromagnetic valve 611. The output end of the water pump 7 is fixedly connected with a second telescopic tube 514. By setting the flushing pipe 609, it is convenient for the operator to pour water into the filter cartridge 601, so as to flush the surface of the filter net 605 and the inside of the filter cartridge 601. The drain pipe 610 is set to facilitate the removal of impurities, and the electromagnetic valve 611 is convenient to open and close through the PLC controller 513.

[0037] like Figure 3 , Figure 6 and Figure 8 As shown, one end of the second telescopic tube 514 away from the water pump 7 movably passes through the noise reduction shell 401 and the silencer sponge 402 and is fixedly connected to the third telescopic tube 515. One end of the third telescopic tube 515 away from the second telescopic tube 514 is rotatably connected to the connecting hard tube 505. By arranging the second telescopic tube 514 and the third telescopic tube 515, it is convenient to transport water to the transport hard tube 506 through the connecting hard tube 505.

[0038] The method of use and working principle of the device: In the preparation stage, push the device to move it to the side of the breeding pond, and extend the delivery hard pipe 506 above the breeding pond, then step on the brake pads on the universal wheel to fix the device, connect the wiring terminal of the PLC controller 513 and the wiring port inside the device, and then connect the water pump 603 to the external water source.

[0039] During the adjustment stage, the second drive motor 205 is started through the PLC controller 513, and the second drive motor 205 drives one of the two-way threaded rods 202 to rotate, and one of the two-way threaded rods 202 drives one of the wheels 203 to rotate synchronously, and one of the wheels 203 drives the belt 204 to move synchronously, so that the belt 204 drives the other wheel 203 to rotate synchronously, thereby driving the two two-way threaded rods 202 to rotate synchronously, and the four limit blocks 212 limit the four first moving blocks 206, so that the two two-way threaded rods 202 drive the four first moving blocks 206 to move relative to each other, and under the action of the four first U-shaped blocks 208, the four second U-shaped blocks 209 and the four first connecting rods 210, the lifting plate 207 drives the four support rods 213 to move upward, thereby driving the conveying hard pipe 506 to move upward and move the conveying hard pipe 506 to a suitable height.

[0040] During the filtering stage, the water pump 7 is started through the PLC controller 513, and the water pump 7 draws water into the filter cartridge 601 through the pumping pipe 603. The filter screen 605 filters and removes impurities from the drawn water. At the same time, the water in the filter cartridge 601 drives the spiral blades 608 to rotate, and the spiral blades 608 drive the rotating rod 606 to rotate, and the rotating rod 606 drives the scraper 607 to rotate. The rotating scraper 607 scrapes the filter screen 605. When the device is finished working, the solenoid valve 611 on the flushing pipe 609 and the sewage pipe 610 is opened through the PLC controller 513, and then water is poured into the flushing pipe 609 to flush the surface of the filter screen 605 and the inside of the filter cartridge 601, so that the impurities are discharged through the sewage pipe 610.

[0041] During the noise reduction stage, the water pump 7 will generate certain vibrations during operation, and the noise generated inside the noise reduction shell 401 is absorbed by the sound-absorbing sponge 402. At the same time, when the water pump 7 vibrates, the mounting plate 404 is forced to move downward, and the hydraulic damping rod 403 is squeezed. At this time, under the action of the third U-shaped block 409 and the second connecting rod 410, the second moving block 408 is driven to move, and the second moving block 408 moves to squeeze the shock-absorbing spring 407. Under the elastic potential energy of the shock-absorbing spring 407 and the damping action of the hydraulic damping rod 403, the vibration force is reduced.

[0042] During the water inlet oxygenation stage, the water filtered by the filter cartridge 601 passes through the first telescopic tube 602, the second telescopic tube 514 and the third telescopic tube 515 and then enters the connecting hard tube 505, and then is sprayed out through the delivery hard tube 506 and the spray hole 507, so that the water dissolves the external oxygen and falls on the surface of the culture pond. The first drive motor 511 is started by the PLC controller 513, and the first drive motor 511 drives the one-way threaded rod 503 to rotate, and the limit rod 502 limits the one-way threaded rod 503, so that the moving seat 504 drives the connecting hard tube 505 to move. Since the gear 510 and the rack 509 are meshed and connected, the connecting hard tube 505 moves and rotates at the same time, thereby The conveying hard pipe 506 is driven to move and rotate at the same time. When the moving seat 504 moves to contact one of the sensors 512, one of the sensors 512 receives a signal that the moving seat 504 has moved to the target position. One of the sensors 512 transmits the signal to the PLC controller 513. After receiving the signal, the PLC controller 513 starts the first drive motor 511 to reverse, so that the moving seat 504 moves in the opposite direction. When the moving seat 504 moves in the opposite direction and contacts another sensor 512, similarly, the PLC controller 513 starts the first drive motor 511 to rotate forward, so that the conveying hard pipe 506 reciprocates, and oxygenation is performed while water is entering the culture pond.

10. An oxygenation method for an aquaculture oxygenation device, characterized in that: The aquaculture oxygenation device according to claim 9 is used, comprising the following steps: S1: The second driving motor (205) is started through the PLC controller (513), so that the two bidirectional threaded rods (202) rotate synchronously, and the two bidirectional threaded rods (202) drive the four first moving blocks (206) to move relatively, and under the coordination of the first U-shaped block (208), the second U-shaped block (209) and the connecting rod (210), the lifting plate (207) and the four supporting rods (213) rise, and the conveying hard pipe (506) is lifted to the required height; S2: The water pump (7) is started through the PLC controller (513), and the water pump (7) pumps water into the filter cartridge (601). The filter screen (605) filters impurities. At the same time, the water in the filter cartridge (601) drives the spiral blade (608) to rotate, thereby driving the scraper (607) to scrape the filter screen (605). The solenoid valves (611) on the flushing pipe (609) and the sewage pipe (610) are opened through the PLC controller (513), and then water is poured into the filter cartridge (601) through the flushing pipe (609), flushing the filter screen (605) and the filter cartridge (601), so that the impurities can be discharged through the sewage pipe (610); S3: The water pump (7) generates vibration during operation, and the noise-absorbing sponge absorbs the noise. At the same time, the vibration causes the mounting plate (404) to move downward, and the hydraulic damping rod (403) is squeezed. At the same time, the second moving block (408) is driven to move under the action of the third U-shaped block (409) and the second connecting rod (410). The shock-absorbing spring (407) is squeezed by the second moving block (408) and begins to contract. The elastic potential energy of the shock-absorbing spring (407) and the damping action of the hydraulic damping rod (403) jointly reduce the vibration force. S4: The water pump (7) draws water into the filter cartridge (601), and then the water passes through the first telescopic tube (602), the second telescopic tube (514) and the third telescopic tube (515) and enters the connecting hard tube (505), and then is sprayed out through the delivery hard tube (506) and the spray hole (507), so that the water dissolves the external oxygen and falls on the surface of the breeding pond. Then, the first drive motor (511) is started through the PLC controller (513), thereby driving the delivery hard tube (506) to move and rotate at the same time; S5: When the movable seat (504) moves to contact one of the sensors (512), one of the sensors (512) transmits a signal to the PLC controller (513). After receiving the signal, the PLC controller (513) starts the first drive motor (511) to rotate in reverse, so that the movable seat (504) moves in the reverse direction. When the movable seat (504) moves in the reverse direction and contacts another sensor (512), similarly, the PLC controller (513) starts the first drive motor (511) to rotate forward, so that the conveying tube (506) can reciprocate.
