Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a device for promoting the attachment of American black mussels to a pond water inlet. Background Art

[0002] The American black mussel, also known as the zebra mussel, is native to the Pacific and Atlantic coasts of tropical America. It is a typical invasive species. The American black mussel has a strong ability to adapt to the environment and can tolerate salinity levels of 2 to 40. It has a high reproduction rate and can easily form high-density clusters of the same species after entering a new water body and become the dominant species in the area. It is a very harmful fouling organism. It is densely distributed under the cabin or in the pipes, causing damage to the engine or propeller of the ship and slowing down the speed of the ships. It attaches to hydraulic structures such as the sluice gates of pumped power stations, corroding the hydraulic structures, and will also block the buildings after death and falling off. It attaches to oyster farming facilities such as cages, sinking cages, floats and oyster shells, competing with oysters for food, which also has a great impact on the oyster farming industry, reducing production by 60%-70%.

[0003] In recent years, the larvae of American black mussels have been densely distributed in the breeding ponds, pond walls, gates and bottoms through water exchange of breeding ponds and inflow of natural seawater from the outside. First, they absorb a large amount of nutrients such as phytoplankton and organic debris in the water, compete with farmed shellfish for food, inhibit the growth and development of farmed shellfish, and affect the quality of aquatic products, and even die of emaciated due to lack of feed; resulting in low concentration of unicellular algae in the pond and clear and transparent water quality, which is easy to breed large-scale reproduction of Enteromorpha and cause secondary harm. Second, it reduces the habitat area of ​​farmed organisms and can cover the beach of farmed shellfish, causing them to suffocate and die; third, after excessive reproduction in the pond, they die and rot due to lack of feed or sudden changes in the environment, causing hypoxia at the bottom and the production of a large number of toxic substances, which harms the farmed organisms in the pond and even kills them. Therefore, we propose an American black mussel attachment device at the water inlet of the pond to promote the concentrated attachment of larvae, reduce the larval content in the breeding pond and the harm of breeding.

[0029] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] The utility model provides Figure 1-4 The American black mussel attachment device at the water inlet of the pond shown comprises a gate frame 1, a filter cone cavity 2 is provided at the middle end of the gate frame 1, and a threaded attachment frame 3 is provided inside the filter cone cavity 2, the threaded attachment frame 3 comprises an attachment frame 301, an outer filter hole 302, a frame 303, screws 304, a spiral ring 305, an attachment ring 306, an attachment layer 307 and an inner filter hole 308, and the outer filter holes 302 are distributed on the outer wall around the attachment frame 301, one end of the attachment frame 301 is connected to the frame 303, and screws 304 are distributed on the surface of the frame 303, the inner wall of the attachment frame 301 is distributed with a spiral ring 305, and the attachment ring 306 is attached to one side of the spiral ring 305, the inner wall of the attachment ring 306 is provided with an attachment layer 307, and the inner filter hole 308 is opened inside the attachment layer 307;

[0031] In order to maintain the filtration and attachment of black mussel eggs during the drainage process of the aquaculture pond, Figure 3-4As shown, the attachment layer 307 is evenly distributed along the inner wall around the attachment ring 306, and the inner filter holes 308 are evenly opened in irregular shapes along the surface of the attachment layer 307. When the black mussel eggs enter the attachment frame 301 through the drainage water, since the attachment frame 301 itself adopts a conical structure, when the eggs in the water flow flow into the attachment frame 301 along the conical inner wall, the water flow will pass through the spiral ring 305 and the conical structure, so that the water flow increases the contact with the attachment layer 307 on the inner wall of the attachment ring 306 when it is discharged. The surface allows the eggs attached to the water flow to stay and adhere to the uneven structure of the attachment layer 307 surface during the spiral discharge process, thereby reducing the introduction of eggs from the external water flow. Since the outer filter hole 302 is in contact with the inner filter hole 308, during the attachment process, a portion of the attached eggs are discharged into the filter layer 202 inside the cavity frame 201 through the inner filter hole 308 opened on the surface of the attachment layer 307 and the outer filter hole 302 that is in contact and connected. This reduces the content of eggs discharged into the water and also facilitates the subsequent cleaning of the equipment.

[0032] In order to facilitate the cleaning of the attachment treatment device after filtering and attaching mussel eggs, Figure 3-4 As shown, the frame 303 and the attachment frame 301 form a detachable structure through screws 304, and the spiral rings 305 and the attachment rings 306 are arranged in layers along the inner wall of the attachment frame 301. After the device has been placed and used for a long period of time, the screws 304 at the front end of the frame 303 can be unscrewed to complete the detachment of the frame 303 and the attachment frame 301, so that the worker can take out each set of interlocking attachment rings 306 and spiral rings 305 on the inner wall of the attachment frame 301 one by one for cleaning, so that it is easy to continue to use, and the overall operation and cleaning process is convenient.

[0033] like Figure 1 As shown, the gate frame 1 includes a plate frame 101, a top plate 102, a bolt 103, a fluff 104 and a ground plug 105, and the top plate 102 is arranged at the top of the plate frame 101, the bolts 103 are distributed at both ends of the top plate 102, the fluff 104 is connected to both ends of the plate frame 101, and the ground plug 105 is arranged at the bottom end of the plate frame 101;

[0034] In order to keep the gate frame 1 stable when placed at the pond inlet, Figure 1 As shown, the plate frame 101 and the top plate 102 are integrated, and the bolts 103 are symmetrically distributed along the two ends of the top plate 102, the fluff 104 is connected to the middle of the two ends of the plate frame 101, and the ground plugs 105 are equidistantly arranged along the bottom end of the plate frame 101. When using this device to divert water to the breeding pond, the top plate 102 at the top of the plate frame 101 and the bolts 103 at both ends can keep the attachment device stable in the water diversion gate, and the ground plugs 105 distributed at the bottom of the plate frame 101 can be inserted into the underwater beach of the gate when installed, so as to further improve the stability of the gate installation.

[0035] like Figure 2As shown, the filter cone chamber 2 includes a chamber frame 201, a filter layer 202, an inner chamber 203, a water inlet 204 and a drain port 205, and the inner wall of the chamber frame 201 is connected to the filter layer 202, the inner chamber 203 is arranged at the center of the chamber frame 201, and the water inlet 204 is arranged at one end of the inner chamber 203, and the drain port 205 is arranged at the other end of the inner chamber 203;

[0036] Finally, in order to maintain the stability of the adhesion surface during the entire water inflow process, such as Figure 2 As shown, the filter layer 202 is evenly arranged along the inner wall around the cavity frame 201, and the cavity frame 201 is fixedly connected to the gate frame 1. A conical structure design is adopted inside the cavity frame 201 and the cavity frame 201 body to cooperate with the drainage process to increase the contact surface between the water flow and the overall attachment device during the introduction process, thereby increasing the egg attachment efficiency and quantity, and the filter layer 202 adopts a nylon scraping style. When a part of the attached eggs are discharged into the filter layer 202 inside the cavity frame 201 through the inner filter holes 308 opened on the surface of the attachment layer 307 and the outer filter holes 302 that are connected and fit, the high-density nylon scraping around the inner wall of the filter layer 202 will form a baleen structure, thereby intercepting and filtering excess eggs, thereby improving the filterability during the attachment process, and further enhancing the control effect of the pond water diversion process on black mussels.

[0037] In summary, when the attachment device is used, first, when using this device to divert water to the breeding pond, the top plate 102 at the top of the plate frame 101 can be set up at the water inlet position, and then the bolts 103 at both ends of the top plate 102 are nailed into the installation position to fix it. At the same time, the ground plugs 105 distributed at the bottom of the plate frame 101 are inserted into the underwater beach of the gate when installed to keep the attachment device stable at the water diversion gate. When in use, the water flow from the inlet is discharged into the water inlet 204 of the cavity frame 201, and then discharged from the drain port 205 to the breeding pond. During the drainage process, since the attachment frame 301 itself adopts a conical structure, when the eggs in the water flow flow into the attachment frame 301 along the conical inner wall, the water flow will pass through the spiral ring 305 and the conical structure, so that the water flow increases when discharged with the attachment ring 306. The contact surface of the wall attachment layer 307 allows the eggs attached to the water flow to stay and adhere to the uneven structure of the attachment layer 307 surface during the spiral discharge process, and when a part of the attached eggs are discharged into the filter layer 202 inside the cavity frame 201 through the inner filter hole 308 opened on the surface of the attachment layer 307 and the outer filter hole 302 that is connected and fits, the high-density nylon hairs around the inner wall of the filter layer 202 will form a baleen structure, thereby intercepting and filtering the excess eggs. After the device has been placed and used for a long period of time, the screws 304 at the front end of the frame 303 can be unscrewed to complete the detachment of the frame 303 from the attachment frame 301, and the worker can take out and clean each set of interlocking attachment rings 306 and spiral rings 305 on the inner wall of the attachment frame 301 one by one, and then reinstall them for continued use.
