Description

Technical Field

[0001] The present invention relates to the technical field of marine environment observation equipment, and in particular to a marine environment comprehensive observation system capable of avoiding the influence of seawater tide on the observation depth. Background Art

[0002] In the field of marine environment observation, buoy systems and seabed-based systems are the two main means of observation.

[0003] The buoy system is a comprehensive online monitoring device based on modern sensor technology, automatic control technology, and Internet of Things communication technology. It can conduct real-time observation and data collection of hydrological, meteorological, and water quality observation factors, and is widely used in water quality analysis, marine environmental observation, and wind energy resource exploration. Its core technologies include multi-parameter data acquisition, automatic power supply, and intelligent control, which enable all-weather continuous monitoring of hydrological and meteorological parameters, water quality indicators, and location information. The buoy system consists of three core components: an intelligent sensor array, a multi-energy complementary power supply module, and a data acquisition and transmission unit. It supports the simultaneous measurement of water quality, hydrological, meteorological, and other parameters. Its communication system is compatible with 4G networks and satellite transmission, enabling real-time transmission of monitoring data.

[0004] However, the existing traditional buoy system uses a multi-anchor structure for anchoring to achieve real-time collection and transmission of underwater video and profile water quality data. Its construction is difficult and costly, and it cannot achieve water quality profile monitoring in harsh environments such as strong winds and waves, resulting in the loss of monitoring data.

[0005] The seabed-based system can realize the observation of underwater video, bottom water quality, and hydrological elements. In the case of offshore or offshore platforms far away, due to power supply difficulties and the system being deployed on the seabed, real-time data transmission and long-term deployment cannot be achieved. The continuous working time of the system is limited, and data collection is delayed. Affected by offshore fishing operations and seabed siltation, the seabed-based system may be lost and cannot be recovered, resulting in large economic losses.

[0006] With the emergence of new demands for marine environmental observations, such as profile observations and real-time underwater observations, the above two observation methods have major drawbacks and cannot meet new observation needs or have great limitations.

[0007] For profile observation, the existing traditional method is mainly to use a buoy equipped with a winch or anchor to mount multiple devices. The winch's forward and reverse motion is used to deliver the sensor to the specified water depth via a load-bearing cable. During typhoons or high tides, observations cannot be carried out due to the influence of wind speed, waves, and currents, resulting in data loss. The method of mounting multiple devices on the anchor for profile observation requires multiple devices to achieve the function, and underwater maintenance is difficult, the maintenance cycle is short, and the equipment and maintenance costs are high. It is also affected by sea conditions. Under the influence of wind, waves, and currents on the anchor system, the vertical position of the anchor system is offset, making accurate profile observation impossible. Summary of the Invention

[0008] The object of the present invention is to provide a comprehensive marine environment observation system to solve at least one technical problem existing in the above-mentioned background technology.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions: The present invention provides a comprehensive marine environment observation system, including a buoy tower, which is equipped with solar panels, a control box, a water intake pump, a battery compartment and meteorological equipment. A water quality monitoring device is arranged inside the control box. The system also includes a bottom sinker and a support pipe. The support pipe is connected between the bottom sinker and the buoy tower. A plurality of diversion holes are provided on the support pipe. A floating block is provided inside the support pipe. The bottom of the floating block is connected to a plurality of water intake pipes, which are respectively used to take water samples at different depths. The top of the floating block is provided with a plurality of top spring tubes, and the top of each water intake pipe passes through the floating block and is respectively connected to a top spring tube, and the other end of the top spring tube is connected to the water quality monitoring device. The bottom of the floating block is connected to a support pipe, and the top of the support pipe is connected to the water quality monitoring device. The bottom of the support pipe is connected to a bottom spring tube, and the bottom of the support tube is connected to a bottom spring tube, which is used to extract water samples from the bottom layer in the support pipe.

[0010] Furthermore, both ends of the supporting pipe are connected to the bottom sinking stone and the buoy tower respectively through connecting flanges.

[0011] Furthermore, a counterweight block is provided at the inner bottom of the support pipe, and the bottom end of the bottom spring tube is connected to the counterweight block.

[0012] Furthermore, an underwater camera is provided on the bottom sunken stone, and the underwater camera is connected to the control box through a cable.

[0013] Furthermore, a valve is connected between each top spring tube and the water intake pump.

[0014] The beneficial effects of the present invention are as follows: it can simultaneously realize real-time collection and observation of data on hydrological, meteorological, water quality and other observation elements at different depths above and below the water; it does not require a winch mounted on a buoy or multiple devices mounted on an anchor, thus solving the problem of difficult offshore construction and reducing labor costs; it avoids the problem of profile observation accuracy being affected by extreme environments such as wind speed, waves, currents and tides.

DETAILED DESCRIPTION

[0018] To facilitate understanding of the present invention, the present invention is further explained below with reference to specific embodiments in conjunction with the accompanying drawings. However, the specific embodiments do not constitute a limitation on the embodiments of the present invention.

[0019] Those skilled in the art should understand that the drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily necessary for implementing the present invention.

[0020] like Figure 1 As shown, in one specific embodiment, a comprehensive marine environment observation system is provided, comprising a buoy tower 1 equipped with a solar panel 2, a control box 3, a water pump 15, a battery compartment, and meteorological equipment. The control box 3 houses a water quality monitoring device 4. The buoy tower 1 provides buoyancy support, while the solar panel 2 converts solar energy into electrical energy, which is then transmitted to batteries in the battery compartment for storage. This energy is then used to power electrical devices such as the meteorological equipment, the control box 3, the water pump, and the water quality monitoring device 4, which monitors the quality of the water samples collected.

[0021] The comprehensive marine environment observation system of this embodiment also includes a bottom sinker 5 and a support pipe 6; the support pipe 6 is connected between the bottom sinker 5 and the buoy tower 1. Specifically, the two ends of the support pipe 6 are respectively connected to the bottom sinker 5 and the buoy tower 1 through connecting flanges. The main function of the bottom sinker 5 is to fix the buoy tower 1 to prevent it from shifting with the drift of the ocean current or sinking into the muddy bottom. The support pipe 6 is connected between the bottom sinker 5 and the buoy tower 1, and serves as a connecting medium between the bottom sinker 5 and the buoy tower 1, so that the buoy tower 1 can avoid displacement under the action of the bottom sinker 5, and at the same time prevent the buoy tower 1 from shaking with the waves, thereby ensuring the stability of the buoy tower 1, and allowing the buoy tower 1 to carry more equipment such as the control box 3, meteorological equipment, solar panels 2, etc., to achieve all-round marine environment monitoring. Among them, in order to realize the extraction of water samples at different depths in the support pipe 6, a plurality of diversion holes 7 are provided on the support pipe 6, and the inside of the support pipe 6 is connected to the external seawater through the diversion holes 7, so that seawater samples can be extracted. The evenly distributed diversion holes 7 allow the seawater to exchange freely and reduce the impact on the structure. Therefore, while the support pipe 6 serves as a connecting medium between the bottom sinking stone 5 and the buoy tower 1, it also provides a more stable environment for extracting water samples, avoiding the influence of ocean currents. One or more layers of filter nets can also be set on the inside or outside of the support pipe 6 to filter impurities in the seawater, preventing impurities from being extracted into the water quality monitoring equipment 4 and affecting the accuracy of water quality monitoring or clogging the pipes of the water quality monitoring equipment.

[0022] A plurality of water intake pipes 9 of different lengths are provided in the support pipe 6. Each water intake pipe 9 can be connected to a water intake pump 15 through its own valve 16. Water intake pipes 9 of different lengths can obtain seawater samples at different depths. When it is necessary to monitor the seawater quality at a certain depth, the valve 16 of the water intake pipe 9 with a length reaching the depth is opened, and the water intake pump 15 is started to extract the seawater sample at the depth into the water quality monitoring equipment 4 for water quality monitoring.

[0023] The valve 16 can be a solenoid valve, which is controlled to open and close by the controller in the control box 3. When water needs to be taken, the controller controls the solenoid valve connected to the water intake pipe 9 at the corresponding depth to open, and controls the water intake pump 15 to start to extract seawater samples at that depth.

[0024] In actual applications, the depth of seawater will change due to the influence of tides. In order to ensure that seawater samples of different depths can be normally extracted for monitoring when the depth of seawater changes, a movable float 8 is provided inside the support pipe 6. The float 8 can always float on the water surface. Multiple water intake pipes 9 are connected to the float 8. When the depth of seawater changes, the water intake pipes 9 can always keep taking water samples at a predetermined depth below the water surface.

[0025] For example, in a specific application example, based on the actual conditions such as the depth of the seawater area to be monitored, such as the influence of tides, the maximum depth of the seawater in this area is 20 meters and the minimum is 15 meters. According to the monitoring requirements, water samples are taken at three different depths of about 2 meters, 8 meters, and 12 meters below the water surface. In this case, three water intake pipes 9 of different lengths are set in the support pipe 6. The lengths of the three water intake pipes 9 below the lower surface of the float 8 are about 2 meters, 8 meters, and 12 meters respectively. The water intake pipes 9 are made of hard material. The upper ends of the water intake pipes 9 pass through the float 8 and are then connected to their respective valves 16 through different pipelines. The three valves are then connected to the water intake pump 15. When it is necessary to take a water sample at a depth of 2 meters, the valve 16 of the water intake pipe 9 with a length of 2 meters below the lower surface of the float 8 is opened, the other two valves 16 are closed, and the water intake pump 15 is turned on to draw the seawater sample into the water quality monitoring device 4 for water quality monitoring. When it is necessary to take a water sample at a depth of 8 meters, the valve 16 of the water intake pipe 9, which is 8 meters long and below the lower surface of the float 8, is opened, the other two valves 16 are closed, and the water intake pump 15 is turned on to draw a seawater sample into the water quality monitoring device 4 for water quality monitoring. When it is necessary to take a water sample at a depth of 12 meters, the valve 16 of the water intake pipe 9, which is 8 meters long and below the lower surface of the float 8, is opened, the other two valves 16 are closed, and the water intake pump 15 is turned on to draw a seawater sample into the water quality monitoring device 4 for water quality monitoring.

[0026] In this embodiment, to ensure that the buoy 8 floats with the water surface and prevent the buoy 8 from sinking below or separating from the water surface due to the rigidity of the pipes when the seawater level rises or falls, resulting in failure to properly extract seawater samples to the predetermined depth, a plurality of top spring tubes 10 are provided on the top of the buoy 8. One end of each of the top spring tubes 10 is connected to the multiple water intake pipes 9, and the other end of each of the top spring tubes 10 is connected to the water quality monitoring device 4. The number of top spring tubes 10 corresponds to the number of water intake pipes 9. The top end of each water intake pipe 9 passes through the buoy 8 and is connected to a top spring tube 10. The top spring tubes 10 are then connected to corresponding valves 16. The other end of each valve 16 is connected to a rigid pipe mounted on the buoy tower 1 and connected to a water intake pump 15. The connection and installation of the water intake pump 15 and the rigid pipe are conventional techniques and can be easily implemented by those skilled in the art without inventive effort. The specific installation method will not be further described here. By setting the top spring tube 10, the float 8 can always remain floating on the water surface, avoiding the situation where the float 8 sinks below the water surface due to rising water level, and avoiding the situation where the float 8 leaves the water surface due to falling water level, thereby ensuring the accuracy of the water intake depth.

[0027] The multiple water intake pipes 9 can be rigid pipes made of a rigid material and can pass through the float 8 at different locations and be arranged side by side along the same straight line, ensuring that seawater samples from different depths of the same cross-section can be extracted. To ensure that the float 8 can stably rise and fall with the water surface within the support pipe 6, the float 8 can be configured as a circular shape that matches the support pipe 6, with a diameter slightly smaller than the diameter of the support pipe 6 to ensure that it can move within the support pipe 6.

[0028] To ensure that seawater samples can be consistently extracted from the bottom of the support pipe 6 regardless of the depth of the seawater, a support pipe 11 is connected to the bottom of the float 8. The bottom of the support pipe 11 is connected to a bottom spring tube 12. The top of the support pipe 11 passes through the float 8 and connects to the water quality monitoring device 4. Of course, the support pipe 11 is not directly connected to the water quality monitoring device 4. Instead, after passing through the float 8, it is first connected to a valve 16 through a pipe. The valve 16 then connects to a water pump 15 through a pipe, which in turn connects to the water quality monitoring device. A counterweight 13 is provided at the bottom of the support pipe 6, to which the bottom end of the bottom spring tube 12 is connected. This ensures that when the seawater depth changes, the expansion and contraction of the bottom spring tube 12 ensures that the float 8 remains afloat, while the bottom spring tube 12 is able to consistently extract seawater samples from the bottom of the support pipe 6.

[0029] In practical applications, the water intake pipe 9 can also be a flexible pipe made of flexible material, and the ends of multiple water intake pipes 9 are respectively fixed at different depths of the support pipe 11. The support pipe 11 can be made of stainless steel to prevent corrosion by seawater and ensure a long service life.

[0030] In practical applications, stainless steel can be considered as the material for the support pipe 6. On the one hand, as a connecting medium between the bottom sinking stone 5 and the buoy tower 1, stainless steel has a stronger rigid support function, while protecting the internal water intake components such as the water intake pipe 9 and the spring tube; on the other hand, stainless steel can avoid erosion by seawater, extend its service life, ensure the reliability of water quality monitoring, and reduce maintenance costs.

[0031] In a specific embodiment, an underwater camera 14 is provided on the bottom sunken stone 5, and the underwater camera 14 is connected to the control box 3 via a cable. The underwater camera 14 can collect underwater video data of the monitored water area and upload it to the monitoring service background for observation by monitoring personnel, thereby realizing the collection and observation of underwater hydrological videos.

[0032] In another specific embodiment, in order to monitor the water quality of the surface, middle and bottom layers of the required sea area, the bottom end of the water intake pipe 9 for extracting surface seawater can be directly fixed on the lower surface of the floating block, and the bottom end of the water intake pipe 9 for extracting middle seawater can be fixed in the middle of the support tube 11, and then the bottom seawater sample is extracted through the bottom spring tube 12.

[0033] The comprehensive marine environment observation system described in this embodiment is designed to lower the tide when the buoy 8 within the support pipe 6. At the lowest tide, the top spring tube 10 is in a stretched state, while the bottom spring tube 12 is in a retracted state. At high tide, the buoy 8 rises with the tide. At the highest tide, the top spring tube 10 is in a retracted state, while the bottom spring tube 12 is in a stretched state. This allows for precise cross-sectional monitoring of the surface, middle, and bottom layers. An underwater camera 14 is mounted and secured via pre-reserved fixing holes in the bottom sinker 5. The cable connecting the underwater camera 14 is wrapped around the support pipe 6 and then connected to the control box 3, enabling real-time transmission of underwater video and power supply. The top of the buoy tower 1 can be equipped with meteorological equipment, and the control box 3 houses water quality monitoring equipment 4 and a controller. The controller controls the operation of various pumps, including the water pump, and the switching of valves, sequentially collecting water samples from the surface, middle, and bottom layers into sample cups. The water quality monitoring equipment then tests the samples in the sample cups.

[0034] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solutions disclosed in the present invention without the need for creative work should be included in the scope of protection of the present invention.
