Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, and in particular to a suspended monitoring device based on aquaculture cages. Background Technology

[0002] Cage aquaculture is a fish farming method conducted in waterways. Its overall structure includes a frame, netting, floats, sinkers, and cables. The frame can be made of metal, wood, or bamboo, and its design must consider resistance to wind and waves. The netting includes the net skirt, net bottom, net cover, and feeding channels, and its design comes in various forms, such as square, octagonal, and hexagonal.

[0003] Water quality monitoring helps fish farmers understand water quality conditions in a timely manner, such as dissolved oxygen, pH value, ammonia nitrogen, and nitrite. For example, Chinese Patent Publication No. CN215422301 U discloses an integrated buoy-cage for fish farming, water quality, and biological behavior monitoring. This integrated buoy-cage for fish farming, water quality, and biological behavior monitoring includes a column buoy and a cage farming component. The column buoy has a built-in water quality monitoring component for detecting water quality and an environmental monitoring module for monitoring biological behavior, while the cage farming component is located on the column buoy. The integrated buoy-cage for fish farming, water quality, and biological behavior monitoring provided by this invention forms a unified whole through the column buoy and the cage farming component, essentially a marine ranch column buoy. The presence of a net provides space for fish farming, while the external connecting floats and fixing ribs, while constituting the cage structure, also effectively solve the problem of inaccurate data acquisition caused by vortex-induced vibration of the column buoy.

[0004] In actual operation, the water quality analysis device extracts and analyzes seawater through a water inlet pipe. However, considering that there are many floating objects, silt, and seaweed in the seawater, and there is a lack of measures to filter the seawater, directly extracting and analyzing the seawater can easily lead to blockage of the water inlet pipe or malfunction of the analysis device after long-term use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that lack measures for filtering seawater, and to propose a suspended monitoring device based on a net cage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a suspended monitoring device based on a cage, including a net set between a floating frame and a counterweight. The floating frame is fixedly connected to the upper rope of the net, and a monitoring buoy is set at the top of the net via a central floating platform. The monitoring buoy is equipped with a data acquisition and monitoring device, which includes a monitoring lens and a data acquisition head connected through a data acquisition tube.

[0008] The sampling head is detachably connected to a filter element via a closed assembly. The sampling head and the filter element work together to filter and extract seawater.

[0009] Furthermore, one end of the collecting head is connected to the collecting tube, and the other end is recessed inward to form a receiving cavity, through which the filter element is provided, and multiple water inlet holes are also provided around the collecting head.

[0010] Furthermore, the closing assembly includes a fixing plate and several cover plates. The fixing plate is fixedly connected to the open end of the acquisition head, and its end face is also provided with a through hole that matches the opening of the acquisition head. The fixing plate has several first mating grooves arranged in a circular array along the through hole. The cover plates are slidably connected to the first mating grooves through guide portions, and they close together to close the through hole.

[0011] Furthermore, it also includes a movable plate, the end face of which is provided with a second mating groove corresponding to the guide portion. The second mating groove is slidably connected to the guide portion. A pair of oppositely arranged guide portions extend to the top and are provided with stop plates, which stop the movable plate.

[0012] Furthermore, a connecting rod is rotatably connected to the side of the fixed plate via an extension portion, and a gear is fixedly connected to the top of the connecting rod. The periphery of the movable plate is provided with tooth grooves, and the gear meshes with the tooth grooves to rotate.

[0013] Furthermore, the tail end of the connecting rod is provided with a stop portion, and a fixing portion is provided on the periphery by a spring. The fixing portion is slidably connected to the connecting rod by a limiting member, and its end face is provided with a protrusion that engages with the slot at the bottom of the extension portion.

[0014] The present invention proposes a suspended monitoring device based on a net cage, which has the following advantages: The present invention can monitor the underwater environment through a monitoring lens, and filter and extract seawater in conjunction with a collection tube and collection head. The underwater environment can be judged by analyzing the seawater. Furthermore, the closed component allows for quick replacement of the filter element, preventing the filter element from becoming clogged by silt and seaweed after long-term use and losing its filtering effect. This can greatly reduce the impurities contained in the seawater, prevent the collection tube from becoming clogged, and extend the service life of the analysis device. In addition, the fixing part can fix multiple cover plates to prevent the cover plates from rotating and opening and closing freely, which could cause the filter element to detach from the collection head.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A suspended monitoring device based on a net cage includes a net 3 disposed between a float 1 and a counterweight 2. The float 1 and the upper rope of the net 3 are fixedly connected, and a monitoring buoy 4 is provided at the top of the float via a central floating platform. The monitoring buoy 4 is equipped with a data acquisition and monitoring device, which includes a monitoring lens 41 and a data acquisition head 43 connected via a data acquisition tube 42.

[0023] The collection head 43 is detachably connected to a filter element 44 via a closure component 5. The collection head 43 and the filter element 44 are used together to filter and extract seawater.

[0024] It should be added that the counterweight 2 is connected to the lower line of the net 3 by ropes, which is used to work with the float 1 to pull the net 3 to maintain its shape. Of course, the lower line of the net 3 is connected to the seabed by ropes and anchors.

[0025] The monitoring buoy 4 is equipped with an antenna on its top for transmitting data to the control unit, and a water pump connected to the collection pipe 42 is installed inside it. The water pump sends the seawater drawn by the collection pipe 42 to the detection device, and works with the monitoring lens 41 to detect and analyze the data of the underwater environment.

[0026] Furthermore, one end of the collecting head 43 is connected to the collecting tube 42, and the other end is recessed inward to form a receiving cavity, through which the filter element 44 is provided, and multiple water inlet holes are also provided on the periphery of the collecting head 43.

[0027] Specifically, the filter element 44 is a filter cotton core, which filters mud, sand, seaweed and other impurities in seawater. In addition, the length of the filter cotton core is slightly greater than the length of the receiving cavity. After the closing component 5 closes the opening of the collection head 43, the two ends of the filter cotton core are pressed against the inlet of the collection tube 42 to prevent impurities from entering.

[0028] Furthermore, the closing component 5 includes a fixing plate 51 and several cover plates 52. The fixing plate 51 is fixedly connected to the open end of the collection head 43, and its end face is also provided with a through hole that matches the opening of the collection head 43. The fixing plate 51 has several first mating grooves 53 arranged in a circular array along the through hole. The cover plates 52 are slidably connected to the first mating grooves 53 through guide portions 54, and they are closed together to close the through hole.

[0029] It is worth mentioning that the cover plates 52 have the same structure and are fixedly connected to the guide portion 54. The working method of the closing component 5 can be referred to the closing structure of the camera shutter in the prior art.

[0030] More specifically, it also includes a movable plate 55, the end face of which is provided with a second mating groove 56 corresponding to the guide portion 54. The second mating groove 56 is slidably connected to the guide portion 54. The top of a pair of oppositely arranged guide portions 54 is extended and provided with a stop plate 57, which stops the movable plate 55.

[0031] In specific operation, when the movable plate 55 is rotated, the guide part 54 is driven by the second mating groove 56 to move the cover plate 52. When the guide part 54 is driven, it will move the cover plate 52 along the trajectory of the first mating groove 53. Then the cover plates 52 can be dispersed and closed. By closing the opening of the collection head 43, the opening of the receiving cavity is closed, so as to fix the filter element 44.

[0032] The aforementioned stop plate 57 is used to stop the movable plate 55 and to fix the movable plate 55 to prevent the movable plate 55 from separating from the fixed plate 51.

[0033] In general, the side of the fixed plate 51 is rotatably connected to the connecting rod 511 through the extension portion, the top of the connecting rod 511 is fixedly connected to the gear 512, the periphery of the movable plate 55 is provided with a toothed groove 551, and the gear 512 meshes with the toothed groove 551 to rotate.

[0034] Finally, the end of the connecting rod 511 is provided with a stop and a fixing part 58 is provided on the periphery by a spring 513. The fixing part 58 is slidably connected to the connecting rod 511 by a limiting member, and its end face is provided with a protrusion 581, which engages with the slot 66 at the bottom of the extension part.

[0035] It should be noted that the two ends of the spring 513 are fixedly connected to the side of the stop part and the fixed part 58. The limiting member includes a limiting groove and a limiting block. The side of the connecting rod 511 is provided with a limiting groove along the axis. The inner hole of the fixed part 58 is slidably connected to the limiting groove through the limiting block.

[0036] The limiting member is used to circumferentially lock the fixing part 58, and the fixing part 58 is fixed to the fixing plate 51 by the protrusion 581. Then, the connecting rod 511 is locked by the fixing part 58 to prevent the connecting rod 511 from rotating freely. In addition, the fixing part 58 has push-pull parts on both sides.

[0037] Working method: During operation, the fixed part 58 is pulled down by the push-pull part, the fixed part 58 moves down along the limit groove, and the protrusion 581 is disengaged from the fixed plate 51. After the connecting rod 511 is unlocked, the connecting rod 511 is rotated to mesh with the tooth groove 551 through the gear 512, thereby driving the movable plate 55 to rotate.

[0038] When the movable plate 55 rotates, the guide part 54 is driven by the second mating groove 56 to move the cover plate 52. When the guide part 54 is driven, it will move the cover plate 52 along the trajectory of the first mating groove 53. Then the cover plates 52 can be dispersed and closed, which makes it easy to replace the filter element 44.

[0039] Similarly, rotating the connecting rod 511 in the opposite direction causes the movable plate 55 to drive the cover plate 52 to close the opening of the collection head 43, thus fixing the filter element 44. The protrusion 581 engages with the movable plate 55 to fix the connecting rod 511. The collection and monitoring device extracts and analyzes seawater through the collection tube 42 and the collection head 43, and transmits data to the control unit through the top antenna.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
