Description

Technical Field

[0001] The present invention relates to the technical field of environmental analysis, and in particular, to a system for evaluating the impact of land-based aquaculture on the marine environment. Background Art

[0002] Land-based aquaculture refers to a mode of aquaculture that artificially simulates an aquatic environment on land and uses technologies such as a recirculating water system and water quality regulation. This mode breaks through the limitations of traditional water area aquaculture and can achieve efficient aquaculture anywhere, especially suitable for areas with water resource shortages or limited land resources.

[0003] During the aquaculture process, pollutants will inevitably penetrate into the surrounding environment through seepage and then enter the water body around the land-based aquaculture farm. Therefore, land-based aquaculture has potential pollution risks to the surrounding water environment and even to the marine environment. However, there is currently a lack of means for evaluating the degree of impact of land-based aquaculture on the surrounding water environment and the marine environment.

[0004] In view of this, the present application is specifically proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a system for evaluating the impact of land-based aquaculture on the marine environment, which can effectively evaluate the potential impact degree of land-based aquaculture on the surrounding water environment and the marine environment, and can provide reference and guidance for water environment treatment and the optimization and upgrading of land-based aquaculture.

[0006] The embodiments of the present invention are implemented as follows:

[0007] A system for evaluating the impact of land-based aquaculture on the marine environment includes: a data center and a water quality monitoring terminal.

[0008] There are multiple water quality monitoring terminals, and all of them are electrically connected to the data center.

[0009] The water quality monitoring terminal is used to be arranged in the water body around the land-based aquaculture farm to obtain the water quality data around the land-based aquaculture farm.

[0010] The data center is used to determine the upstream water body and the downstream water body around the land-based aquaculture farm according to the hydrodynamic model. The water quality data of the water quality monitoring terminal in the upstream water body is used as upstream data, and the water quality data of the water quality monitoring terminal in the downstream water body is used as downstream data.

[0011] The data center is used to determine the types and amounts of pollutants released by the land-based aquaculture farm into the water body according to the upstream data and the downstream data.

[0012] The data center is also used to determine the water flow path between the land-based aquaculture farm and the ocean according to the hydrodynamic model, and determine the types and amounts of residual pollutants entering the ocean based on the water flow path, pollutant types, pollutant amounts, and the self-purification ability of the water flow path.

[0013] The data center is also used to evaluate the degree of impact on the marine environment based on the types and amounts of residual pollutants.

[0014] Furthermore, the water quality monitoring terminal includes: a water quality detection sensor, a base body, a first sliding member, and a second sliding member.

[0015] One end of the base body is used to extend into the water body, denoted as the water inlet end. The other end of the base body is used to be arranged outside the water body, denoted as the outside-water end. The base body is provided with a detection channel that penetrates to the surface of the water inlet end.

[0016] The first sliding member is slidably fitted in the detection channel and is slidably sealed with the inner wall of the detection channel. The second sliding member is arranged on the side of the first sliding member away from the outside-water end and can be slidably fitted in the detection channel. When the second sliding member is slidably fitted in the detection channel, the second sliding member is slidably sealed with the inner wall of the detection channel.

[0017] The first sliding member and the second sliding member are arranged at intervals, and the water quality detection sensor is installed on the side of the first sliding member close to the second sliding member.

[0018] The first sliding member and the second sliding member are driven by a driving mechanism. The driving mechanism is used to drive the first sliding member and the second sliding member to move between a first sliding position and a second sliding position. When the first sliding member and the second sliding member are at the first sliding position, the first sliding member is located at one end of the end face of the detection channel close to the water inlet end, and the second sliding member is located outside the detection channel. When the first sliding member and the second sliding member are at the second sliding position, both the first sliding member and the second sliding member are located inside the detection channel.

[0019] Furthermore, a first accommodation cavity is formed in the base body. A first piston is slidably fitted in the first accommodation cavity and is slidably sealed with the inner wall of the first accommodation cavity. A first elastic member is abutted between the first piston and one end wall of the first accommodation cavity.

[0020] A first flow channel and a second flow channel are formed in the end wall of the first accommodation cavity away from the first elastic member. A one-way mechanism is arranged in the first flow channel to prevent the fluid in the first accommodation cavity from leaving the first accommodation cavity through the first flow channel.

[0021] The inner wall of the detection channel is provided with an input hole, an output hole and a drain hole. There are multiple input holes, and the multiple input holes are arranged at intervals along the axial direction of the detection channel. The output hole is located on one side of the input hole close to the outer end of the water and is arranged at intervals with the input hole. The drain hole is located on one side of the detection channel far from the output hole and is correspondingly arranged with the output hole. The input holes are all communicated with the first flow channel, and the output hole is communicated with the second flow channel.

[0022] When the first sliding member and the second sliding member are at the first sliding position, the first sliding member closes all the drain hole, the output hole and the input hole. When the first sliding member and the second sliding member are at the second sliding position, the area between the first sliding member and the second sliding member is communicated with the input hole farthest from the outer end of the water.

[0023] The driving mechanism is further configured to drive the first sliding member and the second sliding member to move to a third sliding position, and the third sliding position is located on one side of the second sliding position away from the first sliding position. During the process of the first sliding member and the second sliding member moving from the second sliding position to the third sliding position, the driving mechanism is further configured to drive the second sliding member to approach the first sliding member. When the first sliding member and the second sliding member move to the third sliding position, the distance between the first sliding member and the second sliding member reaches the lower threshold value, the area between the first sliding member and the second sliding member is communicated with the input hole farthest from the water inlet end, the drain hole and the output hole are closed by the first sliding member, and the water in the area between the first sliding member and the second sliding member is conveyed to the first accommodating cavity through the input hole.

[0024] The driving mechanism is further configured to drive the first sliding member and the second sliding member to move to a fourth sliding position, and the fourth sliding position is located on one side of the third sliding position away from the second sliding position. When the first sliding member and the second sliding member are at the fourth sliding position, the input holes are all disconnected from the area between the first sliding member and the second sliding member, the output hole and the drain hole are both connected to the area between the first sliding member and the second sliding member, the first piston pushes the water in the first accommodating cavity through the output hole under the action of the first elastic member, and the water in the area between the first sliding member and the second sliding member is discharged through the drain hole to flush the water quality detection sensor.

[0025] Further, a second accommodating cavity is further formed in the base body. The second accommodating cavity is arranged in parallel and at intervals with the first accommodating cavity. A second piston is slidably fitted in the second accommodating cavity, and the second piston is slidably sealed with the inner wall of the second accommodating cavity. A second elastic member is abutted between the second piston and one end wall of the second accommodating cavity. A third flow channel is formed in one end wall of the second accommodating cavity away from the second elastic member.

[0026] The inner wall of the detection channel is provided with air outlet holes and exhaust holes. The air outlet holes and the exhaust holes are respectively arranged on opposite sides of the detection channel, and the air outlet holes and the exhaust holes are correspondingly arranged and are located on the side of the output hole and the liquid discharge hole close to the outer end of the water. The air outlet holes communicate with the third flow channel.

[0027] One end of the first accommodating cavity close to the first elastic member is provided with a first notch communicating with the outside. The first piston is fixedly connected with a first rod body, and the first rod body extends outside the first accommodating cavity through the first notch. A push plate is fixedly connected to the outer end of the first rod body.

[0028] One end of the second accommodating cavity close to the second elastic member is provided with a second notch communicating with the outside. The second piston is fixedly connected with a second rod body, and the second rod body extends outside the second accommodating cavity through the second notch. A mating plate is fixedly connected to the outer end of the second rod body, and the mating plate is located on the side of the push plate away from the first accommodating cavity.

[0029] The second piston is provided with an air inlet hole penetrating through it, and the air inlet hole is fitted with a one-way valve flap, so that when the second piston moves towards the side where the second elastic member is located, the outside air can enter the side of the second piston away from the second elastic member through the air inlet hole.

[0030] When the water in the area between the first sliding member and the second sliding member is conveyed into the first accommodating cavity through the input hole, the push plate pushes the mating plate, so that the second piston moves towards the side where the second elastic member is located.

[0031] When the first sliding member and the second sliding member are located at the first sliding position, the second sliding position, the third sliding position and the fourth sliding position, the air outlet holes and the exhaust holes are both closed by the first sliding member.

[0032] The driving mechanism is further used to drive the first sliding member and the second sliding member to move to the fifth sliding position, and the fifth sliding position is located on the side of the fourth sliding position away from the third sliding position.

[0033] When the first sliding member and the second sliding member are located at the fifth sliding position, the air outlet holes and the exhaust holes are both communicated with the area between the first sliding member and the second sliding member, and the output hole and the liquid discharge hole are both disconnected from the area between the first sliding member and the second sliding member, so that the second piston under the action of the second elastic member pushes the air in the second accommodating cavity into the area between the first sliding member and the second sliding member through the third flow channel to perform air flow cleaning and drying on the water quality detection sensor.

[0034] Furthermore, a relief groove is also formed on the inner wall of the detection channel. The relief groove is formed by the depression of the inner wall of the detection channel and extends along the axial direction of the detection channel. The relief groove is located on the side of the air outlet holes and the exhaust holes close to the outer end of the water. A rack arranged along the axial direction of the detection channel is provided in the middle of the bottom of the relief groove.

[0035] The first sliding member has a transmission inner cavity, and a relief notch communicating the transmission inner cavity with the outside is formed in the side wall of one end of the first sliding member away from the second sliding member.

[0036] The driving mechanism includes: a driver, a transmission rod, a mating gear, and a transmission gear unit.

[0037] The driver is in transmission cooperation with the first sliding member. The mating gear is installed in the relief notch with damping. The transmission rod is arranged along the axial direction of the detection channel and penetrates the first sliding member. The transmission rod extends into the transmission inner cavity and is in sliding cooperation with the first sliding member, and there is a sliding seal between the transmission rod and the first sliding member. The transmission rod is fixedly connected to the second sliding member, and the mating gear and the transmission rod are in transmission cooperation through the transmission gear unit. Wherein, the transmission ratio between the mating gear and the transmission rod is less than 1.

[0038] When the first sliding member and the second sliding member move between the first sliding position and the second sliding position, the mating gear is located on the side of the rack near the water inlet end, and the mating gear does not rotate.

[0039] When the first sliding member and the second sliding member move between the second sliding position and the third sliding position, the mating gear meshes with the rack and is driven by the rack, so that the second sliding member approaches the first sliding member.

[0040] When the first sliding member and the second sliding member move between the third sliding position and the fifth sliding position, the mating gear is located on the side of the rack away from the water inlet end, and the mating gear does not rotate.

[0041] Further, a sliding groove is formed on the side surface of the mating gear. The sliding groove is recessed from the side wall of the mating gear, and the groove is perpendicular to the rotation axis of the mating gear.

[0042] Guide ribs are arranged on the groove side wall of the relief groove. The guide ribs are arranged along the axial direction of the detection channel, and guide ribs are provided on both the side of the rack near the water inlet end and the side away from the water inlet end.

[0043] When the first sliding member and the second sliding member move between the first sliding position and the second sliding position, the guide rib on the side of the rack near the water inlet end is in sliding cooperation with the sliding groove to prevent the mating gear from rotating.

[0044] When the first sliding member and the second sliding member are located at the second sliding position, the guide rib on the side of the rack near the water inlet end just separates from the sliding groove, and the mating gear just meshes with the rack.

[0045] When the first sliding member and the second sliding member are located at the third sliding position, the guide rib on the side of the rack away from the water inlet end just cooperates with the sliding groove, and the mating gear just separates from the rack.

[0046] When the first sliding member and the second sliding member move between the third sliding position and the fifth sliding position, the guiding rib on the side of the rack away from the water inlet end slidably cooperates with the sliding groove to prevent the mating gear from rotating.

[0047] Further, both the first elastic member and the second elastic member are springs.

[0048] Further, when the first piston abuts against the end of the first receiving cavity away from the first elastic member, and the second piston abuts against the end of the second receiving cavity away from the second elastic member, the pushing plate abuts against the mating plate.

[0049] Further, a plurality of input holes are uniformly spaced along the axial direction of the detection channel.

[0050] Further, both the first receiving cavity and the second receiving cavity are arranged along the axial direction of the detection channel.

[0051] The beneficial effects of the technical solution of the embodiment of the present invention include:

Detailed implementation manners

[0066] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Components of the embodiments of the present invention generally described and illustrated in the accompanying drawings herein can be arranged and designed in a variety of different configurations.

[0067] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but is merely representative of selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0068] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0069] Terms such as "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0070] In addition, terms such as "parallel" and "perpendicular" do not mean that components are required to be absolutely parallel or perpendicular, but can be slightly inclined. For example, "parallel" only means that its direction is more parallel relative to "perpendicular", and does not mean that the structure must be completely parallel, but can be slightly inclined.

[0071] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, terms such as "arrangement", "installation", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0072] To overcome the deficiencies in the prior art, this embodiment provides a land-based aquaculture impact assessment system for the marine environment. The land-based aquaculture impact assessment system for the marine environment includes: a data center (not shown in the figure) and a water quality monitoring terminal.

[0073] There are multiple water quality monitoring terminals, and the water quality monitoring terminals are all electrically connected to the data center for sending relevant data to the data center.

[0074] The water quality monitoring terminal is used to be arranged in the water body around the land-based aquaculture farm to obtain the water quality data around the land-based aquaculture farm. Among them, the water quality monitoring terminals can be arranged at preset intervals according to the actual situation. The water quality monitoring terminals need to be arranged in the water bodies around the land-based aquaculture farm, including but not limited to: surface currents, underground undercurrents, etc.

[0075] The data center is used to determine the upstream water body and the downstream water body around the land-based aquaculture farm according to the hydrodynamic model, that is, to confirm the upstream water body and the downstream water body of the land-based aquaculture farm according to the movement direction of the water body shown in the hydrodynamic model. Among them, the water quality data of the water quality monitoring terminals in the upstream water body are used as upstream data, and the water quality data of the water quality monitoring terminals in the downstream water body are used as downstream data.

[0076] The data center is used to determine the types and amounts of pollutants released by the land-based aquaculture farm into the water body according to the upstream data and the downstream data, that is, to determine the types and amounts of pollutants released by the land-based aquaculture farm into the water body according to the differences in pollutants in the upstream data and the downstream data.

[0077] The data center is also used to determine the water flow path between the land-based aquaculture farm and the ocean according to the hydrodynamic model, and to determine the types and amounts of residual pollutants entering the ocean according to the water flow path, the types of pollutants, the amounts of pollutants, and the self-purification ability of the water flow path.

[0078] The data center is also used to evaluate the degree of impact on the marine environment according to the types and amounts of residual pollutants.

[0079] Through this design, the water body conditions around the land-based aquaculture farm can be monitored more comprehensively, and at the same time, the potential impact degree on the marine environment can be predicted and evaluated according to the hydrodynamic model.

[0080] Generally speaking, the system for evaluating the impact of land-based aquaculture on the marine environment provided by the embodiments of the present invention can effectively evaluate the potential impact degree of land-based aquaculture on the surrounding water environment and the marine environment, and can provide reference and guidance for water environment treatment and the optimization and upgrading of land-based aquaculture.

[0081] Specifically, in this embodiment, please refer to Figures 1-6 , the water quality monitoring terminal includes: a water quality detection sensor 100, a base body 200, a first sliding member 300, and a second sliding member 400.

[0082] One end of the base body 200 is used to extend into the water body, denoted as the water inlet end 210. The other end of the base body 200 is used to be arranged outside the water body, denoted as the water outside end 220.

[0083] The substrate 200 is provided with a detection channel 230. The detection channel 230 extends from the water outer end 220 of the substrate 200 to the water inlet end 210, and the detection channel 230 penetrates to the surface of the water inlet end 210.

[0084] The first sliding member 300 is slidably fitted in the detection channel 230 and is in close contact with and slidably sealed against the inner wall of the detection channel 230. The second sliding member 400 is provided on the side of the first sliding member 300 away from the water outer end 220. The second sliding member 400 can be slidably fitted in the detection channel 230 and can also slide along the detection channel 230 and leave the detection channel 230 from one port of the detection channel 230 close to the water inlet end 210. When the second sliding member 400 is slidably fitted in the detection channel 230, the second sliding member 400 is in close contact with and slidably sealed against the inner wall of the detection channel 230.

[0085] The first sliding member 300 and the second sliding member 400 are arranged at intervals. The first sliding member 300 extends along the axial direction of the detection channel 230. The water quality detection sensor 100 is installed on the end face of the first sliding member 300 close to the second sliding member 400.

[0086] The first sliding member 300 and the second sliding member 400 are driven by a driving mechanism. The driving mechanism is used to drive the first sliding member 300 and the second sliding member 400 to move between a first sliding position and a second sliding position.

[0087] When the first sliding member 300 and the second sliding member 400 are at the first sliding position, the first sliding member 300 is located at one end of the detection channel 230 close to the end face of the water inlet end 210, and the second sliding member 400 is located outside the detection channel 230. In this embodiment, when the first sliding member 300 and the second sliding member 400 are at the first sliding position, the end face of the first sliding member 300 close to the second sliding member 400 is flush with one port of the detection channel 230 close to the water inlet end 210, as Figure 1 shown.

[0088] When the first sliding member 300 and the second sliding member 400 are at the second sliding position, both the first sliding member 300 and the second sliding member 400 are located inside the detection channel 230. The area between the first sliding member 300 and the second sliding member 400 is filled with water, as Figure 2 shown.

[0089] With this design, when it is necessary to detect the water quality of the water body, the driving mechanism is used to control the first sliding member 300 and the second sliding member 400 to be at the first sliding position, and the water quality detection sensor 100 can continuously detect the flowing water body.

[0090] When the water body does not need to be detected temporarily, the driving mechanism can be used to control the first sliding member 300 and the second sliding member 400 to be in the second sliding position, the water quality detection sensor 100 is recovered into the detection channel 230, and the opening of the detection channel 230 is closed by the second sliding member 400, so as to prevent the water quality detection sensor 100 from being damaged by floating objects or suspended matters when it is in the external water body for a long time.

[0091] Further, a first accommodating cavity 240 is formed in the base body 200. A first piston 241 is slidably fitted in the first accommodating cavity 240, and the first piston 241 is in close contact with and slidably sealed against the inner wall of the first accommodating cavity 240. A first elastic member 242 is abutted between the first piston 241 and one end wall of the first accommodating cavity 240. Optionally, the first accommodating cavity 240 is arranged along the axial direction of the detection channel 230, and the first elastic member 242 is abutted between one end wall of the first accommodating cavity 240 close to the outer water end 220 and the first piston 241. In the natural state, under the elastic force of the first elastic member 242, the first piston 241 is attached to one end wall of the first accommodating cavity 240 close to the water inlet end 210.

[0092] A first flow channel 243 and a second flow channel 244 are formed in one end wall of the first accommodating cavity 240 away from the first elastic member 242. A one-way mechanism (not shown in the figure) is arranged in the first flow channel 243. The one-way mechanism allows the fluid to enter the first accommodating cavity 240 through the first flow channel 243 and prevents the fluid in the first accommodating cavity 240 from leaving the first accommodating cavity 240 through the first flow channel 243. The one-way mechanism can be a one-way valve, a valve flap, etc., and is not limited thereto.

[0093] Input holes 231, output holes 232 and drain holes 233 are formed in the inner wall of the detection channel 230. There are a plurality of input holes 231, and the plurality of input holes 231 are arranged in parallel and at intervals along the axial direction of the detection channel 230. Optionally, the axis lines of the input holes 231 are all arranged along the radial direction of the detection channel 230.

[0094] The output holes 232 are located on one side of the input holes 231 close to the outer water end 220 and are arranged at intervals from the input holes 231. The drain holes 233 are located on one side of the detection channel 230 away from the output holes 232 and are arranged corresponding to the output holes 232. Optionally, the drain holes 233 and the output holes 232 are coaxially arranged and are both arranged along the radial direction of the detection channel 230.

[0095] The input holes 231 are all communicated with the first flow channel 243, and the output holes 232 are communicated with the second flow channel 244.

[0096] When the first sliding member 300 and the second sliding member 400 are at the first sliding position, the first sliding member 300 closes all the drain holes 233, output holes 232 and input holes 231, as Figure 1 shown.

[0097] When the first slider 300 and the second slider 400 are at the second sliding position, the area between the first slider 300 and the second slider 400 communicates with the input hole 231 that is farthest from the water outer end 220, as Figure 2 shown.

[0098] The driving mechanism is also used to drive the first slider 300 and the second slider 400 to move to the third sliding position, and the third sliding position is located on the side of the second sliding position away from the first sliding position.

[0099] During the process of the first slider 300 and the second slider 400 moving from the second sliding position to the third sliding position, the driving mechanism is also used to drive the second slider 400 to approach the first slider 300. During this process, since the second slider 400 gradually approaches the first slider 300, the water in the area between the first slider 300 and the second slider 400 is transported to the first accommodating cavity 240 through the input hole 231.

[0100] When the first slider 300 and the second slider 400 move to the third sliding position, the distance between the first slider 300 and the second slider 400 reaches the lower limit threshold (the lower limit threshold can be flexibly set according to actual needs), the area between the first slider 300 and the second slider 400 communicates with the input hole 231 that is farthest from the water inlet end 210, and the liquid discharge hole 233 and the output hole 232 are closed by the first slider 300. At this time, the amount of water stored in the first accommodating cavity 240 reaches the maximum, as Figure 3 shown.

[0101] The driving mechanism is also used to drive the first slider 300 and the second slider 400 to move to the fourth sliding position, and the fourth sliding position is located on the side of the third sliding position away from the second sliding position.

[0102] When the first slider 300 and the second slider 400 are at the fourth sliding position, the input hole 231 is disconnected from the area between the first slider 300 and the second slider 400, the output hole 232 and the liquid discharge hole 233 are both connected to the area between the first slider 300 and the second slider 400, and the first piston 241 pushes the water in the first accommodating cavity 240 out through the output hole 232 under the action of the first elastic member 242, and the water in the area between the first slider 300 and the second slider 400 is discharged through the liquid discharge hole 233, and the generated water flow can wash the water quality detection sensor 100, as Figure 4 shown.

[0103] With this design, when it is no longer necessary to continue detecting the water body, the water collected in the first accommodation chamber 240 can be used to flush the water quality detection sensor 100, ensuring the cleanliness of the water quality detection sensor 100, thereby guaranteeing the stability of the water quality detection sensor 100 and facilitating the extension of the service life of the water quality detection sensor 100.

[0104] Furthermore, a second accommodation chamber 250 is also formed in the base body 200. The second accommodation chamber 250 is arranged in parallel and at an interval with the first accommodation chamber 240. A second piston 251 is slidably fitted in the second accommodation chamber 250, and the second piston 251 is in close contact with and slidably sealed against the inner wall of the second accommodation chamber 250. A second elastic member 253 is abutted between the second piston 251 and one end wall of the second accommodation chamber 250. A third flow channel 254 is formed in one end wall of the second accommodation chamber 250 away from the second elastic member 253 (i.e., the end wall of the second accommodation chamber 250 close to the water inlet end 210). In the natural state, under the elastic force of the second elastic member 253, the second piston 251 is in close contact with the end wall of the second accommodation chamber 250 close to the water inlet end 210.

[0105] Air outlet holes 234 and exhaust holes 235 are formed in the inner wall of the detection channel 230. The air outlet holes 234 and the exhaust holes 235 are respectively arranged on opposite sides of the detection channel 230, and the air outlet holes 234 and the exhaust holes 235 are correspondingly arranged and are located on the side of the output hole 232 and the liquid discharge hole 233 close to the outer end 220 of the water. The air outlet holes 234 are communicated with the third flow channel 254. Optionally, the air outlet holes 234 and the exhaust holes 235 are coaxially arranged and are both arranged along the radial direction of the detection channel 230.

[0106] A first notch 245 communicating with the outside is formed in one end of the first accommodation chamber 240 close to the first elastic member 242. The first piston 241 is fixedly connected with a first rod body 246. The outer diameter of the first rod body 246 is smaller than the inner diameter of the first notch 245. The first rod body 246 extends outside the first accommodation chamber 240 through the first notch 245, and a push plate 247 is fixedly connected to the outer end of the first rod body 246. In this embodiment, the first rod body 246 extends along the axial direction of the first accommodation chamber 240, and the push plate 247 is arranged perpendicular to the first rod body 246.

[0107] A second accommodation cavity 250 is provided with a second notch 255 communicating with the outside at one end close to the second elastic member 253. The second piston 251 is fixedly connected with a second rod body 256. The outer diameter of the second rod body 256 is smaller than the inner diameter of the second notch 255. The second rod body 256 extends out of the second accommodation cavity 250 through the second notch 255. A mating plate 257 is fixedly connected to the outer end of the second rod body 256. The mating plate 257 is located on the side of the push plate 247 away from the first accommodation cavity 240. In this embodiment, the second rod body 256 extends along the axial direction of the second accommodation cavity 250, and the mating plate 257 is perpendicular to the second rod body 256.

[0108] The second piston 251 is provided with an air inlet hole 252 passing through it. The air inlet hole 252 is fitted with a one-way valve flap (not shown in the figure). When the second piston 251 moves towards the side where the second elastic member 253 is located, the outside air can push open the one-way valve flap and enter the side of the second piston 251 away from the second elastic member 253 through the air inlet hole 252. When the second piston 251 is stationary or moves towards the water inlet end 210, the one-way valve flap closes.

[0109] When the water in the area between the first sliding member 300 and the second sliding member 400 is conveyed to the first accommodation cavity 240 through the input hole 231, the push plate 247 pushes the mating plate 257, so that the second piston 251 moves towards the side where the second elastic member 253 is located. During this process, the outside air can push open the one-way valve flap and enter the side of the second piston 251 away from the second elastic member 253 through the air inlet hole 252, and the second accommodation cavity 250 realizes the collection of gas.

[0110] When the first sliding member 300 and the second sliding member 400 are at the first sliding position, the second sliding position, the third sliding position, and the fourth sliding position, both the air outlet hole 234 and the exhaust hole 235 are closed by the first sliding member 300.

[0111] The driving mechanism is further configured to drive the first sliding member 300 and the second sliding member 400 to move to a fifth sliding position, and the fifth sliding position is located on the side of the fourth sliding position away from the third sliding position.

[0112] When the first slider 300 and the second slider 400 are at the fifth sliding position, both the air outlet hole 234 and the exhaust hole 235 communicate with the area between the first slider 300 and the second slider 400, and both the output hole 232 and the liquid discharge hole 233 are disconnected from the area between the first slider 300 and the second slider 400. At this time, since the water in the first accommodation chamber 240 has been discharged, the first piston 241, the first rod body 246, and the push plate 247 have all been reset. The mating plate 257 is no longer blocked by the push plate 247. Under the action of the second elastic member 253, the second piston 251 pushes the air in the second accommodation chamber 250 into the area between the first slider 300 and the second slider 400 through the third flow channel 254. The pushed air is finally discharged through the exhaust hole 235, and the generated air flow can clean and dry the water quality detection sensor 100 by air flow, such as Figure 5 as shown.

[0113] Through this design, when it is no longer necessary to continue detecting the water body, after flushing the water quality detection sensor 100, the water quality detection sensor 100 can also be cleaned and dried by air flow, which can further improve the cleanliness of the water quality detection sensor 100, thus better ensuring the stability of the water quality detection sensor 100 and also facilitating further extension of the service life of the water quality detection sensor 100.

[0114] Furthermore, please combine Figures 7-9 to see that a relief groove 236 is also formed on the inner wall of the detection channel 230. The relief groove 236 is formed by the depression of the inner wall of the detection channel 230 and extends along the axial direction of the detection channel 230. The relief groove 236 is located on the side of the air outlet hole 234 and the exhaust hole 235 close to the outer water end 220. A rack 237 arranged along the axial direction of the detection channel 230 is provided in the middle of the bottom of the relief groove 236. The length of the rack 237 is less than the length of the relief groove 236.

[0115] The first slider 300 has a transmission inner cavity 310, and a relief notch 320 communicating the transmission inner cavity 310 with the outside is formed on the side wall of the end of the first slider 300 away from the second slider 400.

[0116] The drive mechanism includes: a driver (not shown in the figure), a transmission rod 510, a mating gear 520, and a transmission gear unit 540.

[0117] The driver is in transmission cooperation with the first slider 300 and is used to drive the first slider 300 to move along the detection channel 230.

[0118] The mating gear 520 is installed in the relief notch 320 in a damped manner. The transmission rod 510 is arranged along the axial direction of the detection channel 230 and penetrates through the first sliding member 300. The transmission rod 510 extends into the transmission cavity 310 and is in sliding fit with the first sliding member 300. A sliding seal is provided between the transmission rod 510 and the first sliding member 300.

[0119] The transmission rod 510 is fixedly connected to the second sliding member 400, and the mating gear 520 and the transmission rod 510 are in transmission fit through a transmission gear unit 540.

[0120] Among them, the transmission ratio between the mating gear 520 and the transmission rod 510 is less than 1. That is to say, during the rotation of the mating gear 520, if the teeth of the mating gear 520 move a distance of s along the circumferential direction, then the distance that the mating gear 520 drives the transmission rod 510 to move through the transmission gear unit 540 is greater than s.

[0121] When the first sliding member 300 and the second sliding member 400 move between the first sliding position and the second sliding position, the mating gear 520 is located on the side of the rack 237 close to the water inlet end 210. The mating gear 520 is not engaged with the rack 237 and does not rotate.

[0122] When the first sliding member 300 and the second sliding member 400 move between the second sliding position and the third sliding position, the mating gear 520 meshes with the rack 237 and is driven by the rack 237 to make the second sliding member 400 approach the first sliding member 300.

[0123] When the first sliding member 300 and the second sliding member 400 move between the third sliding position and the fifth sliding position, the mating gear 520 is located on the side of the rack 237 far from the water inlet end 210. The mating gear 520 is not engaged with the rack 237 and does not rotate.

[0124] Furthermore, a sliding groove 530 is provided on the side surface of the mating gear 520. The sliding groove 530 is formed by a recess in the side wall of the mating gear 520, and the groove is perpendicular to the rotation axis of the mating gear 520.

[0125] Guide ribs 238 are provided on the groove side wall of the relief groove 236. The guide ribs 238 are arranged along the axial direction of the detection channel 230. Guide ribs 238 are provided on both the side of the rack 237 close to the water inlet end 210 and the side far from the water inlet end 210.

[0126] When the first sliding member 300 and the second sliding member 400 move between the first sliding position and the second sliding position, the guide rib 238 on the side of the rack 237 close to the water inlet end 210 is in sliding fit with the sliding groove 530 to prevent the mating gear 520 from rotating. As Figure 7 shown.

[0127] When the first slider 300 and the second slider 400 are at the second sliding position, the guiding rib 238 on the side of the rack 237 close to the water inlet end 210 just separates from the sliding groove 530, and the mating gear 520 just meshes with the rack 237. As Figure 8 shown.

[0128] When the first slider 300 and the second slider 400 are at the third sliding position, the guiding rib 238 on the side of the rack 237 away from the water inlet end 210 just mates with the sliding groove 530, and the mating gear 520 just separates from the rack 237. As Figure 9 shown.

[0129] When the first slider 300 and the second slider 400 move between the third sliding position and the fifth sliding position, the guiding rib 238 on the side of the rack 237 away from the water inlet end 210 slidably mates with the sliding groove 530 to prevent the mating gear 520 from rotating.

[0130] Through the above design, the driver can directly complete the entire linkage process only by driving the first slider 300, which is simple and efficient.

[0131] Optionally, both the first elastic member 242 and the second elastic member 253 are springs.

[0132] Optionally, when the first piston 241 fits against the end of the first receiving cavity 240 away from the first elastic member 242, and the second piston 251 fits against the end of the second receiving cavity 250 away from the second elastic member 253, the push plate 247 fits against the mating plate 257.

[0133] Optionally, the plurality of input holes 231 are uniformly spaced along the axial direction of the detection channel 230.

[0134] In summary, the land-based aquaculture impact assessment system on the marine environment provided by the embodiments of the present invention can effectively evaluate the potential impact degree of land-based aquaculture on the surrounding water environment and the marine environment, and can provide reference and guidance for water environment governance and the optimization and upgrading of land-based aquaculture.
