Description

Technical Field

[0001] The invention relates to the technical field of swimming crab breeding, in particular to a bottom oxygenation device for swimming crab breeding. Background Art

[0002] The bottom aeration device for swimming crab farming is to provide enough oxygen to support the normal growth and reproduction of swimming crabs during the farming process. Swimming crab farming generally adopts different forms such as ponds, cages or seawater aquaculture systems. In these systems, due to the large volume of water and high farming density, the dissolved oxygen in the water may be insufficient, so an aeration device is needed to improve the water quality and ensure that there is sufficient oxygen in the water.

[0003] For example, in the "A pond bottom-filling aeration device for swimming crab breeding" with publication number: CN103875589A, the aeration main pipe is installed around the pond, the diameter of the aeration main pipe is 75mm~100mm, and the distance from the bottom of the pond to 10~20cm; the aeration branch pipe is connected to the aeration main pipe through a tee, each of the aeration branch pipes is 8m~10m apart, the diameter of the aeration branch pipe is 20mm~25mm, and the aeration device is arranged in a "mesh" shape as a whole; a plurality of oxygenating structures are drilled through the upward surface of the aeration branch pipe, each of the oxygenating structures is 1m~1.2m apart, and the oxygenating structure is composed of 5~8 oxygenating holes surrounded in a ring, and the aperture of the oxygenating hole is 0.6mm~0.8mm. The present invention increases oxygen through pipe micropores at the bottom of the breeding pond, changes single-point oxygenation into comprehensive oxygenation, upper-layer oxygenation into bottom-layer oxygenation, and dynamic oxygenation into static oxygenation, thereby optimizing the ecological environment of the breeding pond.

[0004] However, in the prior art, although this type of oxygenation device has the effect of changing single-point oxygenation to comprehensive oxygenation, upper-layer oxygenation to bottom-layer oxygenation, and dynamic oxygenation to static oxygenation, and optimizes the ecological environment of the breeding pond, it is lacking in oxygenating waters at different depths. Although swimming crabs are benthic organisms, the water body of the breeding pond is not uniform, and there are differences in oxygen concentration between water layers. If the oxygen in the upper waters of the water body is insufficient, it will affect the overall water quality and circulation of the water body, and may cause stratification of the water body. Especially in warm seasons, when the temperature of the pond water body is high, the dissolved oxygen in the surface waters is easy to decrease. If oxygen is not added in time, an anaerobic layer may be formed on the surface of the water body, thereby affecting the water quality of the entire water body.

[0005] Therefore we propose a bottom oxygenation device for swimming crab culture to solve the above-mentioned problems. Summary of the invention

The material of the connecting pipe B107 is a rubber hose. The design of the rubber hose material of the connecting pipe B107 makes it easy to reel up the connecting pipe B107, thereby avoiding the situation where the connecting pipe B107 is soaked in water for a long time and causes corrosion of the connecting pipe B107 to affect the water quality.

[0023] Embodiment 2: Figure 7-8As shown, a slot 200 is provided on the surface of the gas storage plate 126, and a filter plate 201 is inserted inside the slot 200. The design of the filter plate 201 prevents impurities in the water from falling into the bubbler 127 and causing the bubbler 127 to be blocked. A slide bar A202 is slidably connected inside the gas storage plate 126, and a spring A203 is sleeved on the surface of the slide bar A202. A plug block 204 is fixedly installed on the top of the slide bar A202, and a paddle 205 is fixedly installed on the surface of the plug block 204. A slide groove 206 is provided on the top surface of the gas storage plate 126, and a slider 207 is slidably connected inside the slide groove 206. A paddle 208 is fixedly installed on the top surface of the slider 207, and a scraper 209 is fixedly installed on the bottom surface of the paddle 208. The filter plate 201 is connected to the slot 200. The plug block 204 is slidably connected to the gas storage plate 126, the plug block 204 is slidably connected to the filter plate 201, the paddle plate 208 is slidably connected to the gas storage plate 126, the scraper plate 209 is slidably connected to the filter plate 201, and the sliding design of the scraper plate 209 and the filter plate 201 makes it easy to clean the impurities on the surface of the filter plate 201, thereby preventing the impurities on the surface of the filter plate 201 from falling onto the bubbler 127 when the filter plate 201 is taken out. One end of the spring A203 is connected to the bottom surface of the plug block 204, and the other end is connected to the inner surface of the gas storage plate 126. The design of the spring A203 and the plug block 204 makes it easy to replace the filter plate 201, thereby improving the efficiency of replacing the filter plate 201.

[0024] In this embodiment, by toggling the paddle 208, the paddle 208 will drive the slider 207 to slide in the slide groove 206 when moving, and will also drive the scraper 209 to clean the surface of the filter plate 201. After the impurities on the surface of the filter plate 201 are cleaned, the paddle block is toggled again, and the paddle block drives the plug block 204 to move. After the plug block 204 slides out of the filter plate 201, the filter plate 201 can be pulled out of the slot 200, and then a new filter plate 201 is inserted into the slot 200. At this time, the paddle block is released again, and the plug block 204 slides under the elastic force of the spring A203. After the plug block 20 After the filter plate 201 is inserted into the filter plate 201, the replacement of the filter plate 201 can be completed.

At the same time, the design of the scraper 209 also cleans the impurities on the surface of the filter plate 201 before replacing the filter plate 201. When the filter plate 201 is replaced, the impurities on the surface of the filter plate 201 fall into the bubbler 127, causing the bubbler 127 to be blocked.

[0025] Embodiment 3: According to Figure 9-10As shown, a U-shaped groove 301 is provided inside the culture pond 100, a slide bar B303 is slidably connected inside the culture pond 100, a spring B304 is sleeved on the surface of the slide bar B303, a top plate 300 is fixedly installed at one end of the slide bar B303, a soft pad 302 is fixedly installed on the surface of the top plate 300, and the design of the soft pad 302 plays a role in protecting the frame 120 and the slide 123, thereby preventing the frame 120 and the slide 123 from being scratched by contact with the top plate 300. The top plate 300 is in a U-shape and is slidably connected to the U-shaped groove 301. One end of the spring B304 is connected to the surface of the top plate 300, and the other end is connected to the inner surface of the breeding pond 100. The design of the spring B304 drives the top plate 300 to return to the U-shaped groove 301 after the frame 120 and the slide 123 are moved apart, thereby preventing the swimming crabs in the water from crawling into the U-shaped groove 301 and being pinched when the frame 120 moves.

[0026] In this embodiment, when in use, the frame 120 and the slide 123 are driven to move by the motor B112 and the bidirectional motor C121. After the frame 120 moves to the top plate 300, the top plate 300 is driven to move into the U-shaped groove 301, thereby completing the storage of the frame 120, the slide 123 and the gas storage plate 126, thereby preventing the gas storage plate 126, the bubbler 127 and the connecting pipe B107 from being corroded by being soaked in water for a long time, thereby polluting the water source. After the frame 120, the slide 123 and the air storage plate 126 are away from the top plate 300, the top plate 300 will be reset by the elastic force of the spring B304, thereby preventing the swimming crabs in the breeding pond 100 from crawling into the U-shaped groove 301 and causing the swimming crabs to be pinched by the frame 120 and the slide 123. At the same time, it also makes it easier to maintain and repair the air storage plate 126, the connecting pipe B107 and the bubbler 127.

[0027] The use method and working principle of the device: when the gas storage plate 126 needs to be moved horizontally, the motor B112 only needs to be turned on, and the motor B112 will drive the gear C114. When the gear C114 rotates, it will drive the gear D116 and the gear E117 to rotate through the toothed chain B115, and the gear D116 and the gear E117 will respectively drive the screw rod A118 and the screw rod B119 to rotate. When the screw rod A118 and the screw rod B119 rotate, they will drive the frame 120 to slide in the limit groove 113, thereby driving the slide 123 and the gas storage plate 126 to move horizontally; When the air storage plate 126 needs to be raised or lowered, the bidirectional motor C121 only needs to be turned on. The bidirectional motor C121 will drive the gear F122 to rotate. When the gear F122 rotates, it will drive the carriage 123 to slide inside the frame 120, thereby driving the limiting wheel 125 to roll inside the frame 120. After the carriage 123 drives the air storage plate 126 and the bubbler 127 to move to the water area where oxygenation is required, the air pump 101 can be turned on, thereby realizing oxygenation of water areas of different depths in the culture pond 100. After the oxygenation is completed, When the gas storage plate 126 needs to be reset after completion, the motor A108 only needs to be turned on, and the motor A108 will drive the gear B109 to rotate, and the gear B109 will drive the gear A106 to rotate through the toothed chain A110, thereby driving the winding roller 104 to wind up the connecting pipe B107. The movable design of the gas storage plate 126 has the effect of increasing oxygen in waters of different depths, thereby avoiding the situation where the dissolved oxygen in the surface waters is easily reduced, causing an oxygen-free layer to form on the surface of the water body, thereby affecting the water quality of the entire water body; When the filter plate 201 needs to be cleaned, the dial plate 208 only needs to be moved. The dial plate 208 will drive the slider 207 to slide in the slide groove 206, and will also drive the scraper 209 to clean the surface of the filter plate 201. When the filter plate 201 needs to be replaced, it is only necessary to wait until the impurities on the surface of the filter plate 201 are cleaned, and then the shifting block is shifted, and the shifting block will drive the plugging block 204 to move. After the plugging block 204 slides out of the filter plate 201, the filter plate 201 can be pulled out of the slot 200, and then a new filter plate 201 is inserted into the slot 200. At this time, the shifting block is released, and the plugging block 204 slides due to the elastic force of the spring A203. After the plugging block 204 is inserted into the filter plate 201, the filter plate 201 can be replaced. The design of 201 not only prevents the bubbler 127 from being blocked by impurities, but also facilitates the cleaning and replacement of the filter plate 201, thereby avoiding the damage of the air pump 101 caused by the blockage of the bubbler 127. At the same time, the design of the scraper 209 also cleans the impurities on the surface of the filter plate 201 before replacing the filter plate 201. When the filter plate 201 is replaced, the impurities on the surface of the filter plate 201 fall into the bubbler 127, causing the bubbler 127 to be blocked. When it is necessary to move the air storage plate 126, the bubbler 127 and the connecting pipe B107 out of the water, it is only necessary to turn on the motor B112 and the bidirectional motor C121, and the motor B112 and the bidirectional motor C121 will drive the frame 120 and the slide 123 to move. After the frame 120 moves to the top plate 300, it will drive the top plate 300 to move into the U-shaped groove 301, thereby completing the storage of the frame 120, the slide 123 and the air storage plate 126, thereby preventing the air storage plate 126, the bubbler 127 and the connecting pipe B107 from being blocked. In order to prevent the swimming crabs from being corroded and polluting the water source due to long-term soaking in water, after the frame 120, the slide 123 and the air storage plate 126 are away from the top plate 300, the top plate 300 is reset by the elastic force of the spring B304, thereby preventing the swimming crabs in the breeding pond 100 from crawling into the U-shaped groove 301 and being injured by the frame 120 and the slide 123. At the same time, it also facilitates the maintenance and repair of the air storage plate 126, the connecting pipe B107 and the bubbler 127.
