Description

Technical Field

[0001] This invention belongs to the field of buoy technology, specifically relating to a water quality monitoring buoy. Background Technology

[0002] In recent years, with the unprecedented development of the shipping industry, the volume of maritime freight has increased significantly year by year, and the number of ships entering and leaving ports has continued to increase. Although the public's environmental awareness has been continuously enhanced, international conventions and domestic and foreign laws and regulations for preventing ship pollution have become more and more perfect, the standards have become higher and higher, and the enforcement has become more and more strict, and the administrative law enforcement departments have always paid attention to the investigation and punishment of ship pollution of the marine environment, the phenomena of unidentified oil pollution at sea, ship operation pollution accidents, and ships illegally discharging sewage in port waters still occur from time to time, posing a serious threat to the port water environment.

[0003] Currently, the main methods for marine pollution monitoring include satellite remote sensing, aerial remote sensing, ship remote sensing, fixed-point monitoring, and marine buoy monitoring. Among these, marine buoy monitoring has become an important means of marine pollution monitoring due to its advantages such as high automation, continuous monitoring, no need for manpower and material resources, and convenient maintenance and management. However, marine buoy monitoring still has significant drawbacks. In windy or high-wave conditions, the buoys are unstable and experience significant swaying, which not only has a significant impact on the buoys themselves but also causes them to drift away from the monitoring area due to large waves, affecting the monitoring of marine pollution in the region. Based on this, this application proposes a water quality monitoring buoy that can reduce buoy swaying and drift. Summary of the Invention

[0004] The purpose of this invention is to provide a water quality monitoring buoy that, by setting a first anti-sway mechanism and a second anti-sway mechanism, can significantly reduce the amplitude and frequency of swaying of the buoy when there are large waves.

[0005] The specific technical solution adopted by this invention is as follows:

[0006] A water quality monitoring buoy, including

[0007] The floating body includes an upper floating body and a lower floating body, wherein the lower floating body is provided with a first anti-roll mechanism and a second anti-roll mechanism;

[0008] A marker frame, which is disposed above the upper buoy and is configured as a component of the equipment required for mounting the buoy;

[0009] An anchoring mechanism, configured to fix the buoy in a designated position;

[0010] A monitoring device, installed at the bottom of the lower buoy, is configured to monitor the water quality in the area where the buoy is located;

[0011] The first anti-roll mechanism includes an anti-roll plate disposed on the outer surface of the lower float, and the anti-roll plate has a closed state that is fitted into the surface of the lower float and an open state that is set at an angle to the lower float; the second anti-roll mechanism is disposed on the outer surface of the lower float, and the second anti-roll mechanism has a fixed part and a movable part, wherein the movable part can move along the fixed part to reduce the swaying of the buoy in the vertical direction.

[0012] As a preferred technical solution, the anti-sway plate is movably connected to the lower float via a movable shaft, and the surface of the lower float is provided with a groove that matches the anti-sway plate. When the anti-sway plate is in the closed state, it is fitted into the groove by an interference fit. The outer surface of the anti-sway plate is also provided with a semi-circular ring. When the anti-sway plate is in the unfolded state, one end of the cable is fixed to the semi-circular ring, and the other end is fixed to the bottom of the target frame, so that the anti-sway plate is in the unfolded state.

[0013] As a preferred technical solution, the fixed part of the second anti-roll mechanism is integrally formed with the lower float. One end of the moving part is sleeved in the fixed part and keeps the moving part able to move within the fixed part. A compression spring is also provided in the fixed part. When the moving part moves along the fixed part, the moving part can cause the compression spring to deform. An anti-roll disc is provided at the end of the moving part away from the fixed part.

[0014] As a preferred technical solution, the monitoring equipment includes a water quality monitor, a three-channel sensor, and a phosphate sensor.

[0015] As a preferred technical solution, the top of the frame is equipped with a warning light, a lightning rod, a weather sensor, and a GPS.

[0016] As a preferred technical solution, a solar panel is also provided in the middle of the frame.

[0017] As a preferred technical solution, the diameter of the lower floating body is larger than the diameter of the upper floating body, and the volume of the lower floating body is larger than the volume of the upper floating body.

[0018] As a preferred technical solution, the anchoring mechanism includes an anchor and an anchor chain.

[0019] The technical effects achieved by this invention are as follows:

[0020] This invention incorporates a first anti-sway mechanism. When the buoy is placed in the water, the anti-sway plate of the first anti-sway mechanism unfolds and is kept in an unfolded position by a cable. When the buoy rolls, the anti-sway plate tilts with the buoy and cuts into the water flow. The difference in water flow velocity on both sides generates reverse resistance, which counteracts and reduces the swaying. When the buoy is retracted, the cable can be untied, and the anti-sway plate can be inserted into a groove on the surface of the buoy body with an interference fit. This makes it easy to store, does not take up space, and is convenient to use.

[0021] The present invention incorporates a second anti-roll mechanism. When waves generate troughs and crests, the buoy will sway longitudinally. At this time, the waves will cause the moving part of the second anti-roll mechanism to move upward and compress the compression spring in the fixed part. The elastic potential energy of the compression spring in the fixed part is used to counteract and reduce the swaying of the buoy caused by the waves in the vertical direction.

[0031] Example

[0032] A water quality monitoring buoy includes a buoy body, a buoy frame 9, an anchoring mechanism 5, and monitoring equipment.

[0033] The float comprises an upper float 1 and a lower float 2. The lower float 2 is equipped with a first anti-roll mechanism 4 and a second anti-roll mechanism 3. The first anti-roll mechanism 4 includes an anti-roll plate 41 disposed on the outer surface of the lower float 2, and the anti-roll plate 41 has a closed state that is fitted into the surface of the lower float 2 and an open state that is set at an angle to the lower float 2. The second anti-roll mechanism 3 is disposed on the outer surface of the lower float 2 and has a fixed part 33 and a movable part 32. The movable part 32 moves along the fixed part 33 to reduce the vertical sway of the buoy. It should be noted that the float can be made of polymer materials, such as polyethylene, polypropylene, etc. In this embodiment, the float uses a PE shell filled with PU foam, which takes into account corrosion resistance, buoyancy and cost. The first anti-roll mechanism 4 and the second anti-roll mechanism 3 are also made of PE material. Furthermore, the diameter of the lower float 2 is larger than that of the upper float 1, and the volume of the lower float 2 is larger than that of the upper float 2. The center of gravity of the entire buoy is located on the lower float 2, which can effectively improve the overall stability of the buoy. In addition, those skilled in the art should understand that this water quality monitoring buoy also includes an electronic chamber, which is located inside the float body. The main components and functions of the electronic chamber are equivalent to those of the electronic chamber in traditional water quality monitoring buoys. Those skilled in the art can directly apply the electronic chamber components of existing water quality monitoring buoys to this application, and the specific description of the electronic chamber components and functions will not be provided here.

[0034] The buoy frame 9 is positioned above the upper buoy 1. The buoy frame 9 can be used to install the necessary equipment components for the buoy, such as warning lights 11, lightning rods, GPS and / or BeiDou navigation systems, weather sensors, and solar panels 10. It can also be used to install cameras (not shown in the diagram), radar reflectors (not shown in the diagram), etc., as needed. It should be noted that all of the above components are commercially available products and will not be further described here. The buoy frame 9 can be made of aluminum alloy or stainless steel. There are no special requirements for the structural design of the buoy frame 9; it mainly needs to meet the requirements of the buoy's main structural design and equipment installation.

[0035] The anchoring mechanism 5 is used to fix the buoy in a designated position to complete water quality monitoring of a specific water area. The anchoring mechanism 5 includes an anchor and an anchor chain, with one end of the anchor chain fixed to the center of the bottom of the buoy and the other end of the anchor chain connected to the anchor.

[0036] The monitoring equipment is installed at the bottom of the lower buoy 2 and is configured to monitor the water quality in the area where the buoy is located. It monitors the water quality of the relevant water area in real time and transmits the data to the monitoring backend in real time. The data processing and transmission process and method of water quality monitoring can adopt the existing technology in this field, which will not be described in detail here.

[0037] In a preferred embodiment, the anti-sway plate 41 is movably connected to the lower float 2 via a movable shaft 43, and the surface of the lower float 2 is provided with a groove 21 that matches the anti-sway plate 41. When the anti-sway plate 41 is in the closed state, it is fitted into the groove 21 by an interference fit. The outer surface of the anti-sway plate 41 is also provided with a semi-circular ring 42. When the anti-sway plate 41 is in the unfolded state, one end of a cable (not shown in the figure) is fixed to the semi-circular ring 42, and the other end of the cable (not shown in the figure) is fixed to the bottom of the frame 9, so that the anti-sway plate 41 is in the unfolded state. The anti-sway plate 41, the movable shaft 43, and the float are all made of polymer materials, which are easy to manufacture and lightweight. When the buoy is not submerged in water, the anti-sway plate 41 is inserted into the groove 21 on the surface of the buoy through an interference fit, which facilitates the storage of the anti-sway plate 41 and does not occupy space. When the buoy is submerged in water, the anti-sway plate 41 is first manually pulled out of the groove 21 through the semi-circular ring 42, and then fixed to the bottom of the buoy frame 9 with one end of the self-provided cable, so that the anti-sway plate 41 is in the unfolded state. It should be noted that the unfolding angle of the anti-sway plate 41 can be adjusted according to the experiment or needs, and is not limited here. It should also be noted that the flipping angle of the anti-sway plate 41 can be limited by setting a limiting structure to ensure that the anti-sway plate 41 will not continue to flip upward due to the action of wind and waves after unfolding, thus failing to achieve the anti-sway function. The limiting structure is a common structure in the mechanical field. For example, a combination of limiting protrusion and stop block can be used. When the anti-sway plate 41 flips to the preset angle, the limiting protrusion contacts the stop block to prevent further rotation.

[0038] In a preferred embodiment, the fixed part 33 of the second anti-roll mechanism 3 is integrally formed with the lower float 2. One end of the moving part 32 is fitted inside the fixed part 33, allowing the moving part 32 to move within the fixed part 33. A compression spring 34 is also provided inside the fixed part 33. When the moving part 32 moves along the fixed part 33, it causes the compression spring 34 to deform. An anti-roll disc 31 is provided at the end of the moving part 32 away from the fixed part 33. In this embodiment, the fixed part 33 (cylindrical structure), the moving part 32 (cylindrical structure), and the anti-roll disc 31 in the second anti-roll mechanism 3 are all made of the same polymer material as the float. The compression spring 34 is made of a material with strong corrosion resistance, especially resistant to chloride ion corrosion, such as 316L stainless steel. When waves generate troughs and crests, the buoy will sway longitudinally. At this time, the waves will cause the moving part 32 of the second anti-sway mechanism 3 to move upward and compress the compression spring 34 in the fixed part 33. The elastic potential energy of the compression spring 34 in the fixed part 33 is used to counteract and reduce the swaying of the buoy caused by the waves in the vertical direction.

[0039] In a preferred embodiment, the monitoring device includes a water quality monitor 6, a three-channel sensor 7, and a phosphate sensor 8. The water quality monitor 6, the three-channel sensor 7, and the phosphate sensor 8 are products currently available on the market. For example, the water quality monitor 6 can be an AMT-FB301 multi-parameter water quality sensor, and the three-channel sensor 7 can be a Minos・X three-parameter measuring instrument, etc. No specific limitation is made here.

[0040] Finally, it should be noted that other matters not covered in this application can be implemented using existing technologies in water quality monitoring buoys in this field. The core improvement of this application lies in the provision of a first anti-sway mechanism 4 and a second anti-sway mechanism 3 on the buoy body to reduce the amplitude and frequency of buoy swaying, thereby avoiding any impact on the buoy itself and on water quality monitoring.

[0041] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
