Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection equipment, in particular to a water quality detection device for aquaculture. Background Art

[0002] Aquaculture is a branch of agriculture that utilizes available waters for breeding (including planting) to cultivate aquatic animals and plants using aquaculture techniques and facilities, tailored to the ecological habits of the species and their specific environmental conditions. Aquaculture is categorized into marine aquaculture and freshwater aquaculture, depending on the nature of the waters. Before engaging in marine aquaculture, water quality testing is required to ensure a stable growth environment for the aquatic products.

[0003] Compared with aquaculture in a fixed breeding area, when conducting seawater aquaculture, due to the wide source of seawater, pollutants may be transmitted from all angles and depths in the sea. Once the pollution enters the breeding area, it can cause abnormal water quality, thereby endangering the safety of aquaculture.

[0004] In the current aquaculture process, water quality detection devices are usually installed on the sea surface to conduct real-time water quality detection. However, the detection probe is limited by the position of the buoy and the detection range is limited. When the detection probe data is abnormal, it means that the water quality change has spread to the aquaculture area, which is not conducive to responding in the first time and is likely to have a greater impact on aquaculture.

[0029] See also Figure 1-4 The utility model provides a water quality detection device for aquaculture, comprising a buoy 1, a photovoltaic component 2 is arranged on the top of the buoy 1, and a positioning seat 3 is fixedly connected to the center of the bottom of the buoy 1.

[0030] A sampling kit 4 is provided at the bottom of the positioning seat 3 .

[0031] The sampling kit 4 includes an outer casing 401, and a counterweight block 8 is fixedly connected to the bottom of the outer casing 401. On the one hand, it can improve the stability of the buoy 1 at sea, and on the other hand, it can ensure that the sampling kit 4 can be in a vertical state as much as possible, thereby improving the accuracy of the water quality extraction position.

[0032] The top of the outer casing 401 is fixedly connected with a connecting seat 6, which is threadedly connected to the positioning seat 3. When the buoy 1 docks, the sampling kit 4 and the detection mechanism 5 can be removed together, the water can be drained, and the water quality can be tested.

[0033] A first motor 402 is fixedly connected to the top of the outer casing 401, and a water storage cylinder 403 is slidably connected to the inside of the outer casing 401. A water inlet 408 is provided on one side of the water storage cylinder 403, and an opening 409 corresponding to the water inlet 408 is provided on the side wall of the outer casing 401. A sleeve 404 is fixedly connected to the top of the water storage cylinder 403, and a driving shaft of the first motor 402 is fixedly connected to a screw 405 threadedly connected to the sleeve 404. A limiting groove 406 is provided on the inner wall of the outer casing 401, and a limiting plate 407 is fixedly connected to the outer side wall of the sleeve 404. The limiting plate 407 is slidably connected to the limiting groove 406, so that the sleeve 404 can be vertically lifted and lowered under the limiting action of the limiting groove 406, thereby driving the water storage cylinder 403 to lift and lower.

[0034] Among them, several water storage tanks 7 are provided in the water storage cylinder 403, and a water inlet 408 is provided on the side wall of each water storage tank 7. The water inlet 408 corresponds to the opening 409 one by one, and a waterproof sealing ring is provided around the outer wall of the water inlet 408. When the water inlet 408 and the opening 409 correspond, seawater can be poured into the water storage tank 7 for sampling, which is convenient for subsequent removal for further water quality testing.

[0035] In this embodiment, the outer casing 401 and the water storage tube 403 are both made of corrosion-resistant engineering plastics, which have good corrosion resistance and impact resistance when working underwater and are not easily damaged during long-term underwater work.

[0036] A detection mechanism 5 is fixedly connected to one side of the outer wall of the sampling kit 4 .

[0037] The detection mechanism 5 includes a slide 501, a second motor 502 is fixedly connected to the top of the slide 501, a screw rod 503 is fixedly connected to the driving shaft of the second motor 502, a slide 504 is threadedly connected to the outer wall of the screw rod 503, and a positioning frame 505 is fixedly connected to the side of the slide 504 away from the slide 501, and a detection probe 506 is arranged inside the positioning frame 505.

[0038] A locking bolt 507 is provided on the outer wall of the positioning frame 505. The locking bolt 507 passes through the positioning frame 505 and is rotatably connected to a clip. The clip fits tightly against the outer wall of the detection probe 506. By tightening the locking bolt 507, the detection probe 506 can be easily assembled on the positioning frame 505.

[0039] In this embodiment, an equipment box 9 is fixedly connected to the outer wall of the buoy 1, and a wireless network signal transceiver module corresponding to the detection probe 506 is provided inside the equipment box 9, so as to facilitate the real-time transmission of the data measured by the detection probe 506 to the wireless network terminal of the onshore staff, so as to facilitate the real-time control of water quality data.

[0040] In this embodiment, a waterproof casing is provided on the outside of the first motor 402 and the second motor 502 to provide waterproof protection for the motors and facilitate the normal operation of the motors under seawater.

[0041] During use, the sampling kit 4 with the water storage tank 7 emptied is threadedly installed on the bottom of the positioning seat 3. After the buoy 1 is launched into the water, the buoy 1 can float on the sea surface under the action of the counterweight 8. At the same time, the sampling kit 4 can be located as vertically as possible in the sea. The electronic equipment on the buoy 1, such as the first motor 402 and the second motor 502, are all powered by the photovoltaic component 2. Before sampling, the corresponding power supply lines of the two motors are connected and powered on.

[0042] The sampling kit 4 is equipped with several water storage tanks 7, which can be used to extract seawater of different depths. After the buoy 1 comes ashore, the water can be taken out for depth detection. Steel rings are provided on both sides of the buoy 1, and ropes can be connected to the steel rings. After the buoy 1 is dropped into the deep sea water, it is convenient to retrieve the buoy 1.

[0043] Staff can send signals to the signal transceiver module in the equipment box 9 through wireless network terminals such as mobile phones and computers. The equipment box 9 is also equipped with a control module corresponding to the first motor 402 and the second motor 502, so that staff can remotely control the start and stop of electronic equipment.

[0044] During sampling, the first motor 402 is started to drive the screw 405 to rotate, driving the sleeve 404 to rise and fall under the limiting action of the limiting groove 406, and driving the water storage cylinder 403 to rise. When the water inlet 408 is connected to the corresponding opening 409, the sampling port is opened, and seawater can naturally pass through the sampling port into each water storage tank 7, realizing the synchronous collection of seawater at different depths. After the collection is completed, the water storage cylinder 403 is lowered, and the water inlet 408 is staggered with the opening 409, that is, the sampling port is closed. After the subsequent buoy 1 comes ashore, the outer casing 401 is placed horizontally, the first motor 402 is started again, and the sampling port is reopened, so that seawater at different depths can be released, which is convenient for further detection and research on the seawater quality.

[0045] When the buoy 1 goes into the sea, a real-time water quality detection probe 506 is provided outside the sampling kit 4, which can detect the water quality in real time. At the same time, when the second motor 502 is started, it can drive the slide 504 to slide in the slide 501, adjust the detection depth of the detection probe 506, and use the wireless network signal transceiver module to transmit data to the workstation in real time.

[0046] When multiple sets of water quality data show abnormalities, the sampling kit 4 is activated to sample the water quality, and then the buoy 1 is recovered and the water quality is sent to the laboratory for further in-depth testing and research.
