Description
Technical Field
[0001] This invention relates to the field of suspended beacon technology, specifically to a suspended beacon for hydrological monitoring. Background Technology
[0002] Hydrological monitoring is a complex and comprehensive system engineering project that uses scientific methods to monitor, measure, analyze, and provide early warnings about the spatial and temporal distribution and changing patterns of water in nature. There are many types of hydrological monitoring floats, among which marine buoys are automatic marine hydrological, water quality, and meteorological observation stations mainly composed of observation buoys anchored at sea. Marine buoys are unmanned, relatively highly automated, and excellent marine meteorological and hydrological observation and telemetry equipment. They can collect the basic marine hydrological and meteorological data required for deep-sea scientific research, offshore oil development, port construction, and other purposes on a long-term and continuous basis, in accordance with regulations.
[0003] The basic application of traditional hydrological monitoring buoys is to place them in the water area to monitor the water. However, these buoys have significant drawbacks. On the one hand, since the monitoring process takes place in a water environment, it is necessary to prevent the internal detection equipment from being affected by water and causing short circuits. On the other hand, it is also necessary to ensure the proper storage of monitoring data and prevent data loss. Although current technology has greatly improved the sealing performance of buoys, providing better protection for the internal data storage media and data acquisition devices, and alleviating the above problems to some extent, buoys are still prone to capsizing when there are large waves in the water. After capsizing, the impact force on the buoy will further increase, which can easily lead to the anchor chain breaking, causing the buoy to be washed away by the waves, ultimately resulting in the loss of monitoring data.
[0004] Although existing technologies can connect the buoy to the data collector through a connecting mechanism and protect the cable between the buoy and the data collector, they still have the following limitations: First, the device only protects the cable between the buoy and the data collector, but it cannot protect the floating buoy when the wind and waves are large, which can easily cause the floating buoy to capsize; Second, if the floating buoy is subjected to a large impact and the anchor chain breaks, the data cannot be retrieved, which can easily lead to data loss. Summary of the Invention
[0005] In view of this, the present invention provides a suspended buoy for hydrological monitoring, which can solve the problem that the suspended buoy is easily washed away and monitoring data is lost when the sea surface waves are large in the prior art.
[0006] The technical solution adopted in this invention is as follows:
[0007] A suspended buoy for hydrological monitoring includes a first float, a connecting block, a water quality monitor, an installation structure, a storage device, and a second float.
[0008] The bottom of the first float is provided with a connecting block, and the bottom of the connecting block is fixedly connected with an anchor chain. The interior of the first float is provided with an installation structure for connecting with the connecting block. The water quality monitor is installed on the connecting block.
[0009] The surface of the connecting block has evenly distributed slots for docking with the mounting structure; the interior of the connecting block is equipped with a memory for storing data; the top of the connecting block is provided with evenly distributed second floats; the bottom of the first float is provided with a groove that matches the second float.
[0010] Furthermore, the mounting structure includes a mounting ring fixedly connected to the bottom of the first float. The mounting ring has evenly distributed storage cavities inside. The inner wall of the storage cavity is slidably connected to a locking block along the radial direction of the mounting ring. One end of the locking block passes through the storage cavity and extends into the interior of the corresponding locking groove. The bottom of the end of the locking block near the locking groove is provided with an inclined surface.
[0011] Furthermore, the end of the card block away from the card slot is fixedly connected to the inner wall of the storage cavity by a third spring, and the inside of the mounting ring is provided with connecting channels that are staggered with the storage cavity, and two adjacent storage cavities are connected through the connecting channels.
[0012] Furthermore, the mounting structure also includes a rotating ball, a mounting rod, a connecting rope, a sliding plate, a pull rod, a rotating rod, and a second spring;
[0013] The rotating ball is rotatably connected to the inside of the first float. The first float has a connecting cavity located below the rotating ball. The lower surface of the rotating ball extends into the connecting cavity and is fixedly connected to an installation rod. The lower end of the installation rod is fixedly connected to a connecting rope.
[0014] The first float has a liquid storage chamber located below the connecting cavity. A sliding plate is slidably connected to the inner wall of the liquid storage chamber. A pull rod is fixedly connected to the top of the sliding plate. The upper end of the pull rod extends into the interior of the connecting cavity, and a rotating rod is ball-jointed at the top of the pull rod. The upper end of the rotating rod is fixedly connected to the other end of the connecting rope. A second spring is fixedly connected between the top of the sliding plate and the inner wall of the liquid storage chamber.
[0015] The first float has uniformly distributed flow channels inside. One end of the flow channel is connected to the liquid storage chamber, and the other end of the flow channel is connected to the connecting channel. Hydraulic oil is filled between the bottom of the slide plate and the inside of the liquid storage chamber.
[0016] Furthermore, the buoy also includes an auxiliary structure, which is disposed on the side of the first float. Several adjustment cavities are evenly opened on the side of the first float in the circumferential direction. A squeezing plate is slidably connected to the inner wall of the adjustment cavity. An adjustment rod is fixedly connected to one side of the squeezing plate. The other end of the adjustment rod passes through the first float and is fixedly connected to a trigger plate. A first spring is fixedly connected between the other side of the squeezing plate and the inner wall of the adjustment cavity. A counterweight cavity is formed between the side of the squeezing plate near the trigger plate and the interior of the adjustment cavity.
[0017] The bottom of the first float is provided with evenly distributed connecting pipes that are connected to the adjacent counterweight chambers. The connecting pipes are provided with a first one-way valve to allow water to pass through and enter the counterweight chamber in one direction. The bottom of the first float is provided with evenly distributed drain pipes that are connected to the adjacent counterweight chambers. The drain pipes are provided with a second one-way valve to allow water to be discharged from the counterweight chamber in one direction.
[0018] Furthermore, the end of the drain pipe away from the counterweight cavity bends toward the connecting block and is parallel to the bottom surface of the first float.
[0019] Furthermore, the top of the first float is provided with a mounting shell, inside which a battery and a programmable logic controller are installed; the programmable logic controller is provided with a remote transmission module, which can transmit the data monitored by the water quality monitor to a remote terminal; the top of the first float is provided with a photovoltaic panel located above the mounting shell.
[0020] Beneficial effects:
[0021] 1. When the buoy of this invention is impacted by strong winds and waves, the connecting block separates from the mounting structure on the first float, reducing the impact of wind and waves and the burden on the anchor chain. This facilitates the subsequent recovery of the memory, avoids the loss of monitoring data, and reduces losses.
[0022] 2. When the first float tilts more than 30° due to waves, the rotating ball and the mounting rod rotate synchronously under the action of gravity. The rotating rod is driven by the connecting rope, causing the pull rod to extend from the liquid storage chamber. During this process, the sliding plate can move synchronously to increase the space between the bottom of the sliding plate and the liquid storage chamber. At this time, under the action of the third spring, the locking block can be driven to retract into the storage chamber, thus releasing the limit on the connecting block. The principle is simple, the space utilization is high, the mechanism is ingeniously designed, and the reliability is high.
[0023] 3. When the waves are small, the waves hit the trigger plate of the auxiliary structure of the present invention, causing the trigger plate to move towards the first float. At this time, the squeezing plate can be driven to slide along the inner wall of the adjustment cavity by the adjustment rod. In this process, the internal space of the counterweight cavity can be increased, so that water can be drawn in through the connecting pipe and injected into the counterweight cavity to increase the counterweight in the direction of the waves hitting the first float and reduce the possibility of capsizing.
[0024] 4. The photovoltaic panel set in this invention can achieve long-term self-powering, eliminating the need for frequent battery replacements and breaking through the endurance bottleneck of unattended floating buoys; secondly, the photovoltaic panel combined with battery energy storage can provide power around the clock, avoiding power outages that could lead to monitoring interruptions and ensuring the integrity and reliability of hydrological data.

Detailed Implementation
[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] The present invention provides a suspended buoy for hydrological monitoring, comprising a first float 1, a connecting block 2, a water quality monitor, an installation structure 6, a memory 5, and a second float 201.
[0036] like Figure 1 , Figure 2 , Figure 3 As shown, a connecting block 2 is provided at the bottom of the first float 1, and an anchor chain 4 is fixedly connected to the bottom of the connecting block 2. An anchor claw is provided at the bottom of the anchor chain 4 to contact the bottom of the water. An installation structure 6 for connecting with the connecting block 2 is provided inside the first float 1. A water quality monitor is installed on the connecting block 2. Specifically, a protective shell is provided at the bottom of the connecting block 2, and the surface of the protective shell has evenly distributed water passage grooves. The water quality monitor is installed inside the protective shell for monitoring the water.
[0037] The first float 1 has a mounting shell 101 on its top, which houses a battery and a programmable logic controller (PLC). The PLC transmits data wirelessly to the water quality monitor. The PLC has a remote transmission module that transmits the data to a remote terminal, such as a mobile app or computer. A photovoltaic panel 102 is mounted on top of the first float 1, above the mounting shell 101, converting solar energy into electrical energy stored in the battery to power the PLC, remote transmission module, and water quality monitor. The battery and water quality monitor are connected using two quick-connect male and female cables. During separation, the cables can quickly separate under tension without affecting the separation process.
[0038] The surface of the connecting block 2 has evenly distributed slots 202 for docking with the mounting structure 6; the interior of the connecting block 2 is equipped with a memory 5 for storing data, which can store and record the data monitored by the water quality monitor. The top of the connecting block 2 is provided with evenly distributed second floats 201, and the bottom of the first float 1 is provided with a groove that matches the second float 201.
[0039] Mounting structure 6 includes mounting ring 601, rotating ball 604, mounting rod 613, connecting rope 607, sliding plate 614, pull rod 608, rotating rod, and second spring 606, such as Figure 6 , Figure 7 , Figure 8 As shown.
[0040] The mounting ring 601 is fixedly connected to the bottom of the first float 1. The mounting ring 601 has evenly distributed storage cavities 610 inside. The inner wall of the storage cavity 610 is slidably connected to the locking block 612 along the radial direction of the mounting ring 601. One end of the locking block 612 passes through the storage cavity 610 and extends into the interior of the corresponding locking groove 202. The bottom of the end of the locking block 612 near the locking groove 202 is provided with a slope.
[0041] The end of the card block 612 away from the card slot 202 is fixedly connected to the inner wall of the storage cavity 610 through the third spring 611. The mounting ring 601 has a connecting channel 603 that is staggered with the storage cavity 610 inside. Two adjacent storage cavities 610 are connected through the connecting channel 603.
[0042] The upper end of the connecting block 2 can be inserted into the interior of the mounting ring 601. During this process, the upper end of the connecting block 2 can press the inclined surface of the locking block 612 to retract it into the interior of the receiving cavity 610. At the same time, the locking block 612 can press the third spring 611 during the retraction process. After the connecting block 2 is installed in place, the locking block 612 is adjusted to reset and inserted into the interior of the slot 202, thereby achieving the purpose of limiting the position of the connecting block 2.
[0043] The rotating ball 604 is rotatably connected inside the first float 1. The first float 1 has a connecting cavity 605 located below the rotating ball 604. The lower surface of the rotating ball 604 extends into the connecting cavity 605 and is fixedly connected to the mounting rod 613. The lower end of the mounting rod 613 is fixedly connected to the connecting rope 607.
[0044] The first float 1 has a liquid storage cavity 609 located below the connecting cavity 605. A sliding plate 614 is slidably connected to the inner wall of the liquid storage cavity 609. A pull rod 608 is fixedly connected to the top of the sliding plate 614. The upper end of the pull rod 608 extends into the interior of the connecting cavity 605, and a rotating rod is ball-jointed at the top of the pull rod 608. The upper end of the rotating rod is fixedly connected to the other end of the connecting rope 607. A second spring 606 is fixedly connected between the top of the sliding plate 614 and the inner wall of the liquid storage cavity 609.
[0045] The first float 1 has evenly distributed flow channels 602 inside. One end of the flow channel 602 is connected to the liquid storage cavity 609, and the other end of the flow channel 602 is connected to the connecting channel 603. Hydraulic oil is filled between the bottom of the slide plate 614 and the inside of the liquid storage cavity 609.
[0046] When the first float 1 tilts at an angle exceeding 30° due to the influence of surface waves, it faces a significant risk of capsizing. When the tilt angle exceeds 30°, the surface waves are large, exerting a significant impact on the entire device. This undoubtedly increases the burden on the anchor chain 4, potentially leading to breakage and the entire device being swept away over time. Waves smaller than 30° are generally considered smaller and unlikely to cause the first float 1 to capsize, thus preventing the movement described below.
[0047] When the first float 1 tilts more than 30° due to waves, the rotating ball 604 and the mounting rod 613 rotate synchronously under the action of gravity. Since the mounting rod 613 maintains its center of gravity vertically downward as it rotates with the rotating ball 604, and the tilt of the first float 1 changes their relative positions, the connecting rope 607 drives the rotating rod, causing the pull rod 608 to move synchronously. As the pull rod 608 moves, it synchronously drives the slide plate 614 to move and compresses the second spring 606. The ball joint connection between the rotating rod and the pull rod 608 will not cause jamming due to the offset direction of the mounting rod 613. At the same time, the upward movement of the slide plate 614 increases the space between the bottom of the slide plate 614 and the inside of the liquid storage cavity 609. At this time, under the action of the third spring 611, the locking block 612 can be driven to retract into the storage cavity 610 and the hydraulic oil can be guided back into the storage cavity 609 through the connecting channel 603 and the flow channel 602 for storage. At the same time, the limiting of the connecting block 2 is released, so that the first float 1 and the connecting block 2 can be separated in the case of large wind and waves, reducing the impact of wind and waves and facilitating the subsequent recovery of the memory 5. The setting of the second float 201 can ensure that after the first float 1 is separated, the connecting block 2 can float on the water surface under the action of the second float 201 for easy retrieval later. This avoids the loss of data caused by the anchor chain 4 breaking and the entire device being blown away by wind and waves in bad weather.
[0048] Under normal conditions, the second spring 606 can maintain the position of the slide plate 614, so that the hydraulic oil can be squeezed through the flow channel 602 and the connecting channel 603 and injected into the storage cavity 610 to maintain the position of the locking block 612. When the slide plate 614 moves up, the locking block 612 can retract into the storage cavity 610 under the action of the third spring 611.
[0049] like Figure 4 , Figure 5 As shown, the buoy also includes an auxiliary structure 3, which is disposed on the side of the first float 1. Several adjustment cavities 304 are evenly opened on the side of the first float 1 along the circumference. A pressing plate 305 is slidably connected to the inner wall of the adjustment cavity 304. An adjustment rod 302 is fixedly connected to one side of the pressing plate 305. The other end of the adjustment rod 302 passes through the first float 1 and is fixedly connected to a trigger plate 301. A first spring 306 is fixedly connected between the other side of the pressing plate 305 and the inner wall of the adjustment cavity 304. A counterweight cavity is formed between the side of the pressing plate 305 near the trigger plate 301 and the interior of the adjustment cavity 304.
[0050] The bottom of the first float 1 is provided with evenly distributed connecting pipes 307 that communicate with adjacent counterweight chambers. A first one-way valve 303 is installed inside the connecting pipe 307 to allow water to flow unidirectionally into the counterweight chamber. The bottom of the first float 1 is also provided with evenly distributed drain pipes 309 that communicate with adjacent counterweight chambers. A second one-way valve 308 is installed inside the drain pipe 309 to allow water to flow unidirectionally out of the counterweight chamber. The end of the drain pipe 309 away from the counterweight chamber bends towards the connecting block 2 and is parallel to the bottom surface of the first float 1.
[0051] When the waves are relatively calm, the waves can impact the trigger plate 301, causing it to move towards the first float 1. At this time, the adjusting rod 302 can drive the squeezing plate 305 to slide along the inner wall of the adjusting cavity 304. During this process, the internal space of the counterweight cavity can be increased to form a negative pressure, thereby drawing water through the connecting pipe 307 and injecting it into the counterweight cavity to increase the counterweight in the direction of the waves impacting the first float 1 and reduce the possibility of capsizing. After the water surface becomes calm, the first spring 306 can drive the squeezing plate 305 to reset, thereby draining the water stored in the counterweight cavity through the drain pipe 309.
[0052] Among them, the first one-way valve 303 and the second one-way valve 308 are both relatively mature components in the existing technology. The first one-way valve 303 can allow water to pass through and enter the interior of the counterweight chamber in one direction, while the second one-way valve 308 can allow water to be discharged from the interior of the counterweight chamber in one direction.
[0053] Working principle: When the waves are small, the waves can impact the trigger plate 301, causing it to move towards the first float 1. At this time, the adjusting rod 302 can drive the squeezing plate 305 to slide along the inner wall of the adjusting cavity 304. During this process, the internal space of the counterweight cavity can be increased, thereby drawing water through the connecting pipe 307 and injecting it into the counterweight cavity to increase the counterweight in the direction of the waves impacting the first float 1, reducing the possibility of capsizing. After the water surface becomes calm, the first spring 306 can drive the squeezing plate 305 to reset, thereby draining the water stored in the counterweight cavity through the drain pipe 309. When the first float 1 is affected by the waves and the overall tilt angle exceeds 30°, the tilting mounting rod 613 of the first float 1 can drive the rotating rod through the connecting rope 607 to move the pull rod 608 upwards synchronously, thereby driving the sliding plate 305 to move upwards. The plate 614 moves and compresses the second spring 606. The ball joint connection between the rotating rod and the pull rod 608 will not cause jamming due to the offset direction of the mounting rod 613. At the same time, the upward movement of the sliding plate 614 increases the space between the bottom of the sliding plate 614 and the inside of the liquid storage cavity 609. At this time, under the action of the third spring 611, the locking block 612 can be driven to retract into the storage cavity 610, thereby releasing the restriction on the connecting block 2. This allows the first float 1 to be separated from the connecting block 2 in the event of strong winds and waves, reducing the impact of wind and waves and facilitating the subsequent recovery of the memory 5. The setting of the second float 201 ensures that after the first float 1 is separated, the connecting block 2 can float on the water surface under the action of the second float 201 for easy retrieval. This avoids the loss of data caused by the anchor chain 4 breaking and the entire device being blown away by wind and waves in severe weather.
[0054] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
