Description

Technical Field

[0001] The present invention relates to the technical field of seawater detection equipment, and in particular to a marine water pollutant detection device. Background Art

[0002] The marine industry is the pillar of the economic development of coastal areas. For many humans living by the sea, the ocean is their most important source of food and economy. Once the marine environment is polluted and damaged, the toxic substances in seawater will accumulate continuously through the food chain. Once the heavy metal elements in seawater are ingested by humans, they are difficult to excrete, causing serious diseases, and thus threatening people's lives and safety. Therefore, detecting seawater pollutants is a key link in protecting the marine ecological environment and ensuring the sustainable utilization of marine resources.

[0003] Traditional seawater pollutant detection devices use submersible pumps placed in the sea to pump seawater into seawater analyzers for chemical analysis. However, when the seawater ebbs, the water level around the submersible pump becomes shallower, and the seawater pumped at this time often contains a large amount of sediment, causing deviations in the analysis results of the seawater analyzer and even damaging the seawater analyzer.

The described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Embodiment 1

[0039] As Figures 1 to 2 shown, the present invention provides a marine water pollutant detection device, including:

[0040] A floating board 1, on which a plurality of sliding holes are equidistantly arranged along the circumferential direction;

[0041] A water intake mechanism, which is slidably installed on the floating board 1 through the sliding holes, and a floating block 2 is slidably sleeved at the bottom of the water intake mechanism;

[0042] A limiting component, which is fixedly sleeved on the water intake mechanism and is located above the floating block 2. The limiting component is used to close the water inlet 7 of the water intake mechanism by adjusting the position of the floating block 2;

[0043] A detection box, which is fixedly installed in the middle of the top of the floating board 1. A detection mechanism for detecting seawater is arranged in the detection box. The water outlet of the water intake mechanism is communicated with the detection mechanism, and a drainage port 3 is opened at the bottom of the side wall of the detection box;

[0044] A controller 4 and a signal transceiver 5. The water intake mechanism, the detection mechanism, and the signal transceiver 5 are all electrically connected to the controller 4. The signal transceiver 5 is used to send the detection result of the detection mechanism to the control terminal, and the signal transceiver 5 is used to receive the control instruction output by the control terminal.

[0045] When the present invention is in use, the whole detection device is positioned by a rope to ensure that the detection device samples and detects within a specified range. Through the setting of the floating plate 1, the detection device floats on the sea surface. The water intake mechanism pumps seawater into the detection box for detection, and the detection results are transmitted through the signal transceiver 5. When the sea water ebbs and the water level becomes shallower, under the action of the floating block 2, the water intake mechanism moves upward relative to the floating plate 1, so that a certain distance is always reserved between the water intake of the water intake mechanism and the seabed. When the sea water level continues to become shallower, through the setting of the limit component, the limit component can be used to push the floating block 2 to slide down along the water intake mechanism, so as to block the water inlet 7 of the water intake mechanism by the floating block 2, prevent sediment on the seabed from entering the detection box, and ensure the accuracy of the detection results.

[0046] Further optimized solution, the water intake mechanism includes:

[0047] A vertical water intake pipe 6, the vertical water intake pipe 6 is slidably installed in the sliding hole, an inlet 7 is opened on the bottom side wall of the vertical water intake pipe 6, and the floating block 2 and the limit component are both installed on the vertical water intake pipe 6; a limit plate one 8 is fixedly connected to the bottom end of the vertical water intake pipe 6, and the bottom end of the floating block 2 is in limit cooperation with the limit plate one 8;

[0048] A counterweight 9, the counterweight 9 is fixedly connected to the bottom end of the vertical water intake pipe 6 through a cable 10;

[0049] A water pump 11, the water pump 11 is fixedly installed on the top end of the floating plate 1, the inlet 7 of the water pump 11 is communicated with the top end of the vertical water intake pipe 6 through a telescopic hose 12, the outlet of the water pump 11 is communicated with the detection mechanism, and the water pump 11 is electrically connected to the controller 4.

[0050] Through the setting of the counterweight 9, it can be ensured that when the water depth is sufficient, the vertical water intake pipe 6 can completely enter the sea water. When the water level becomes shallower, the counterweight 9 touches the bottom first, and then as the water level becomes shallower, the floating block 2 on the vertical water intake pipe 6 starts to play a role, driving the vertical water intake pipe 6 to move upward until the limit component on the vertical water intake pipe 6 contacts the bottom end of the floating plate 1 and the bottom end of the floating block 2 contacts the limit plate one 8, at which time the vertical water intake pipe 6 can no longer move upward. At this time, the floating block 2 blocks the inlet 7 on the vertical water intake pipe 6, and the water pump 11 can no longer pump seawater into the detection box. At this time, the controller 4 controls the corresponding water pump 11 to close to prevent the water pump 11 from being damaged by dry burning.

[0051] Further optimized solution, the limit component includes:

[0052] A limit plate two 13, the limit plate two 13 contacts the top end of the floating block 2, and the limit plate two 13 is fixedly sleeved on the vertical water intake pipe 6;

[0053] The third limiting plate 14 is fixedly sleeved on the vertical water intake pipe 6, and the third limiting plate 14 is located above the second limiting plate 13. A plurality of through holes are evenly arranged at equal intervals in the circumferential direction on the third limiting plate 14;

[0054] A plurality of top push rods 15, the bottom end of the top push rod 15 is fixedly connected to the floating block 2, and the top end of the top push rod 15 penetrates through the through hole and is located above the third limiting plate 14.

[0055] When the vertical water intake pipe 6 moves upward through the floating block 2, since the relative position between the floating block 2 and the vertical water intake pipe 6 does not change, the top push rod 15 will also move upward with the vertical water intake pipe 6. When the top end of the top push rod 15 contacts the floating plate 1 and the vertical water intake pipe 6 still moves upward, under the action of the top push rod 15, the floating block 2 moves downward relative to the vertical water intake pipe 6 until the floating block 2 contacts the first limiting plate 8. At this time, the water inlet 7 on the vertical water intake pipe 6 is blocked, and the vertical water intake pipe 6 cannot move upward.

[0056] For a further optimized solution, the detection mechanism includes:

[0057] A water storage tank 16 is arranged in the detection box, and the water outlet of the water pump 11 is communicated with the water storage tank 16;

[0058] A seawater analyzer 17 is located above the water storage tank 16. The seawater analyzer 17 is fixedly installed on the inner wall of the detection box, and the seawater analyzer 17 is electrically connected to the controller 4.

[0059] During use, water is added to the water storage tank 16 through the water pump 11, and the seawater analyzer 17 is used to analyze the water in the water storage tank 16 to detect pollutants in the seawater. When the seawater is repeatedly detected, water is continuously added to the water storage tank 16 through the water pump 11. When the water storage tank 16 is full and overflows, and seawater continuously enters and flows out of the water storage tank 16, the seawater in the water storage tank 16 is replaced, so as to realize the repeated detection of seawater pollutants and make the detection structure more accurate.

[0060] For a further optimized solution, a filter screen 18 is fixedly arranged between the water storage tank 16 and the detection box.

[0061] Through the setting of the filter screen 18, large particle pollutants existing in the seawater can be directly intercepted. By judging the intercepted substances on the filter screen 18 and combining the detection structure of the seawater analyzer 17, the detection of seawater pollutants can be made more accurate.

[0062] For a further optimized solution, to facilitate the removal of substances on the filter screen 18 in the detection box, the detection box includes a box body 19 and a box cover 20 detachably installed on the top of the box body 19, and a sealing ring is provided between the box body 19 and the box cover 20; the controller 4 and the signal transceiver 5 are both installed on the outer top of the box cover 20.

[0063] For a further optimized solution, to facilitate the power supply to the electrical equipment, a storage battery is provided in the box body 19, and the storage battery is fixedly installed on the box cover 20 and is used to supply power to the electrical equipment.

[0064] For a further optimized solution, to extend the service life of the device, a photovoltaic panel is laid on the top end of the box cover 20, and the photovoltaic panel is used to supply power to the storage battery.

[0065] For a further optimized solution, the lengths of multiple vertical water intake pipes 6 are the same; when the floating block 2 contacts the second limiting plate 13, the distance between the top end of the top push rod 15 and the floating plate 1 is the same.

[0066] By setting the multiple vertical water intake pipes 6 to have the same length, when the sea water ebbs and the water level becomes shallower, the detection device can stand on the seabed by the support of the vertical water intake pipes 6, which helps to protect the detection device and extend its service life.

[0067] Embodiment 2

[0068] As Figure 3 shown, the difference between this embodiment and Embodiment 1 is only that the lengths of the multiple vertical water intake pipes 6 increase sequentially; when the floating block 2 contacts the second limiting plate 13, the distance between the top end of the top push rod 15 and the floating plate 1 is the same.

[0069] By setting the vertical water intake pipes 6 with different lengths, seawater at different water depths can be sampled and detected in deep water areas. During detection, only a single water pump 11 needs to be sequentially controlled for water supply.

[0070] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
