Description

Technical Field

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

[0002] A water sampling buoy station is an automatic water quality monitoring laboratory set up in watersheds such as rivers, lakes, reservoirs, and nearshore sea areas. It is a small water quality monitoring system placed in the water area, which uses a water quality monitoring instrument as its core, and combines sensor technology with a buoy body, power supply system, and data transmission equipment.

[0003] Most buoy platforms on the market are based on a buoy body, equipped with various monitoring sensors and supporting equipment. This allows for continuous and automatic monitoring of water quality changes in the tested water body, objectively recording water quality conditions, and timely detection of abnormal changes. This enables water pollution forecasting for target water areas or downstream regions, and the study of water diffusion and self-purification mechanisms. The buoy body is typically made of polyethylene and carries various sensors. To prevent the buoy platform from shifting off course due to wave impact, existing technologies also include chains and anchors. The anchor is connected to the chain, and upon reaching the designated area, the anchor is deployed, along with the chain, to secure the buoy platform in place, preventing displacement under wave action.

[0004] In current technology, during the operation of a buoy platform, in addition to being easily deviated from the predetermined test area due to the action of waves, when the waves are too large, multiple layers of waves will continuously push the buoy platform away from the predetermined test area, causing the chain between the buoy platform and the anchor to tighten. Under the pushing effect of the waves, the buoy platform will rise and be supported by the waves. After the waves move away, since the center of gravity of the buoy platform is above the water surface, there is a risk of it capsizing during the resetting process due to the chain restriction. This may lead to water entering and damaging waterproof components such as the battery inside the buoy platform, or even causing the buoy platform to overturn and sink into the water, resulting in the scrapping of the equipment.

[0011] Preferably, a cleaning brush is fixed to the upper part of the central column via a screw, and the cleaning brush is located at the top of the swing arm; the cleaning brush is used to clean the probe.

[0018] 1.

This can maintain more effective stability when large waves lift the buoy platform body, preventing the impact force of large waves from overturning the entire buoy platform equipment. Secondly, after the large waves move away, the buoy platform body returns to its original position, and the central column generates relative displacement toward the buoy platform body.

With the help of the bristles on the inner side of the cleaning brush, the residual impurities on the probe can be cleaned. Secondly, when the central column moves away from the buoy platform body and has relative displacement, since the anti-clogging screen cylinder is fixed to the buoy platform body, the cleaning brush on the central column will collide with the bottom support of the anti-clogging screen cylinder, which can shake off the residual impurities on the cleaning brush, thereby achieving the purpose of cleaning the cleaning brush.

Detailed Implementation

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 4As shown in the embodiment of the present invention, a water sample testing buoy platform includes a buoy platform body 1; a sealed box 13 is fixedly connected to the top of the buoy platform body 1, and the sealed box 13 is used to carry a probe 5 and a battery; a through hole 19 is opened in the center of the buoy platform body 1, and the probe 5 in the sealed box 13 passes through the buoy platform body 1 via a cable 51; the battery is used to power the probe 5; an anti-clogging screen cylinder 3 is fixedly connected to the bottom of the buoy platform body 1 and coaxially with the through hole 19; the probe 5 is arranged in the anti-clogging screen cylinder 3; a baffle 16 is fixedly connected to the bottom of the through hole 19, and a balance auxiliary unit is connected through the center of the baffle 16, and the balance auxiliary unit includes a central column 45; the central column 45 is connected through the center of the baffle 16; the balance auxiliary unit is used to maintain the stability of the buoy platform body 1 in the water. To avoid the problem of the buoy platform 1 being pushed up to the point of detachment from the water surface when the waves are too large and continuous, causing it to flip over upon returning to the water surface due to the high center of gravity, thus rendering the equipment unusable, the buoy platform 1, made of high-molecular-weight polyethylene, has excellent buoyancy and can easily float on the water surface. After reaching the predetermined area, the probe 5 is manually submerged to measure various parameters in the water, including COD, dissolved oxygen, and other parameters. To prevent aquatic plants from entangled in the probe 5 and causing defects in the data collected, an anti-clogging screen 3 at the bottom of the buoy platform 1 isolates the aquatic plants around it, preventing the probe 5 from getting tangled. Furthermore, the buoy platform 1 may be dislodged from the water surface due to excessively high waves, or the water surface may suddenly drop, potentially causing the buoy platform 1 to become unusable. During the reset process, the float may flip over and sink into the water, rendering the entire float platform unusable. To address this, a central column 45 is installed at the center of the float platform body 1, with chains and anchors connected to its bottom surface. This design limits the position of the float platform body 1. Furthermore, the central column 45 lowers the center of gravity of the entire device, shifting it from the center of the float platform body 1 to below it. Due to the buoyancy of the float platform body 1, the entire float platform remains afloat. The central column 45 extends downwards through the baffle 16 relative to the float platform body 1. Because the central column 45 is restrained by the chains and remains submerged in the bottom water, the overall center of gravity of the device is lowered. When impacted by waves, the chains straighten, and the float platform body 1 can undergo upward relative displacement along the central column 45 under the impact of the waves. Therefore, this design provides effective balance and stability to the float platform body 1.

[0036] like Figures 5 to 6As shown, a stop plate 49 is fixedly connected to the top of the central column 45, and a second spring 18 is fixedly connected between the stop plate 49 and the baffle 16; the second spring 18 is sleeved on the central column 45. To reduce the risk of the central column 45 hitting the bottom after a large wave moves away, a second spring 18 is installed between the baffle 16 and the abutment plate 49. The second spring 18 applies upward pressure to the top of the central column 45. When there is no external force, i.e., no wave pushing the buoy platform upward, the overall water level drops, and the chain changes from a taut state to a slack state. At this time, the central column 45 will be pulled towards the buoy platform body 1 by the elastic potential energy of the second spring 18, causing the central column 45 to move closer to the buoy platform body 1 floating on the water surface. This reduces the risk of the central column 45 hitting the bottom and causing oscillation that could damage the probe 5 carried on the buoy platform body 1. When a wave pushes the buoy platform body 1 upward, it is subjected to an impact force. At this time, the elastic potential energy of the second spring 18 is overcome, which in turn causes a relative displacement between the central column 45 and the buoy platform body 1.

[0037] like Figures 1 to 2As shown, the aforementioned balance auxiliary unit also includes multiple swing arms 41; the bottom of the aforementioned central column 45 is provided with a circular array of contraction grooves 48; the top of the aforementioned swing arms 41 is slidably connected to the contraction grooves 48 via collars; a support arm 44 is slidably connected to the middle of the aforementioned swing arms 41; one end of the aforementioned support arm 44 is slidably engaged with the middle of the swing arms 41, and the other end of the support arm 44 is hinged to the bottom of the contraction grooves 48; a third spring 46 is fixedly connected between the upper part of the contraction grooves 48 and the upper part of the swing arms 41, and the third spring 46 applies pressure to the swing arms 41; a counterweight ball 42 is threadedly connected to the top of the aforementioned swing arms 41 via a screw. To further improve the overall stability of the buoy platform when larger waves arrive, multiple swing arms 41 are installed around the bottom of the central column 45. These swing arms 41, along with the counterweight balls 42 at their bases, further lower the overall center of gravity. However, the buoyancy of the buoy platform 1 is still greater than its overall weight. Furthermore, when the waves move away from the buoy platform 1 and the water surface becomes calmer, to prevent the buoy platform 1 from being unable to detect movement in its surrounding area due to a low center of gravity caused by small waves (i.e., a reduced detection range), the swing arms 41 initially expand outward under the pressure of the third spring 46, maintaining a certain angle (denoted as A) with the central column 45. As the central column 45 moves relative to the buoy platform, i.e., as it approaches the buoy platform, the presence of the anti-clogging screen cylinder 3 causes the swing arms to... 41 is located at the bottom of the anti-clogging screen cylinder 3 and does not contact it. When the swing arm 41 moves up with the central column to contact the bottom of the anti-clogging screen cylinder 3, it will be squeezed and cooperate with the fixed-length contraction groove 48, which will restrict the movement of the swing arm 41. At this time, under the connection of the collar, the collar will slide down on the central column 45 to generate relative displacement, and will drive the support arm 44 to rotate, causing the swing arm 41 to expand further. At this time, the angle between the central column 45 and the swing arm 41 becomes larger. The support arm 44 connects the swing arm 41 and the central column 45, which serves as an auxiliary support. When the angle between the swing arm 41 and the central column 45 becomes larger, it will cause the center of gravity of the buoy platform equipment to shift upward. At this time, under the push of small waves, a larger area can be detected within the allowable range under the connection of the chain and the anchor. Under the pressure of the third spring 46, the collar at the top of the swing arm 41 is at the top of the contraction groove 48 and cannot continue to slide upward.

[0038] like Figures 1 to 2 As shown, a limiting groove 43 is provided on the side of the aforementioned swing arm 41, and one end of the support arm 44 facing the swing arm 41 is slidably connected to the limiting groove 43 via a screw, with the end of the screw fixed by a nut. To improve the connection effect between the support arm 44 and the swing arm 41, the support arm 44 is threaded through the limiting groove 43 on the side of the swing arm 41 via a screw, and the screw is connected by a nut. This facilitates disassembly and maintenance, and prevents the support arm 44 from sliding on the inner side of the swing arm 41 via a pin shaft, where it may be jammed by impurities and unable to rotate at an angle.

[0039] like Figures 6 to 8 , Figure 11 As shown, a cleaning brush 47 is fixed to the upper part of the central column 45 via a screw, and the cleaning brush 47 is located at the top of the swing arm 41. The cleaning brush 47 is used to clean the probe 5. Furthermore, in order to clean the probe 5, a cleaning brush 47 is provided on the upper part of the central column 45, which generates relative displacement between the central column 45 and the buoy platform body 1. That is, when a large wave comes, the central column 45 can move up and down intermittently. At this time, the central column 45 will drive the cleaning brush 47 to intermittently contact the probe 5 and clean the probe 5. By utilizing the impact force of the wave, in conjunction with the central column 45 and the cleaning brush 47, intermittent cleaning of the probe 5 can be achieved, reducing the number of regular maintenance cleanings and improving the overall self-maintenance of the buoy platform equipment.

[0040] like Figure 6 As shown, a plurality of circular arrayed limiting tubes 17 are fixedly connected to the bottom of the baffle 16, and the cable 51 passes through the limiting tubes 17. The top of the probe 5 abuts against the bottom opening of the limiting tube 17. The probe 5 is aligned with the axis of the limiting tube 17. The cleaning brush 47 is arranged correspondingly to the probe 5. In order to prevent the probe 5 from being misaligned or colliding with the cleaning brush 47 when the cleaning brush 47 performs intermittent cleaning, the limiting tubes 17 are used to limit the probe 5 at the end of the limiting tubes 17. The limiting tubes 17 and the cleaning brush 47 are arranged correspondingly so that the cleaning brush 47 can clean the probe 5, which is aligned with the axis of the limiting tube 17, when it moves up and down. The cleaning brush 47 has a U-shaped structure and bristles on its inner side. When it moves up and down axially, the bristles can be used to clean the surface of the probe 5.

[0041] like Figures 6 to 8As shown, the side wall of the buoy platform body 1 is provided with several grooves 14, and a rotating shaft 23 is rotatably connected in each groove 14; the output end of the rotating shaft 23 is used to connect to a generator; a movable undulating platform 21 is rotatably connected in the middle of the rotating shaft 23; a ratchet disk 22 is provided on one side of the movable undulating platform 21, and the rotating shaft 23 is aligned with the axis of the ratchet disk 22; a connecting plate 232 is fixedly connected to one side of the middle of the rotating shaft 23, and a pawl 231 is hinged to the connecting plate 232 via a shaft; the pawl 231 is engaged with the ratchet disk 22; a first spring 15 is fixedly connected between the grooves 14 and the inner side wall of the movable undulating platform 21, and the first spring 15 applies pressure to the movable undulating platform 21. To conserve energy and utilize natural potential energy, a movable undulating platform 21, rotatably connected to the side of the buoy platform 1, rotates under the impact of waves. When the movable undulating platform 21 rotates, it drives the rotating shaft 23 to rotate through the engagement of the ratchet disc 22 and the pawl 231. Since the output end of the rotating shaft 23 is electrically connected to a generator installed inside the buoy platform 1, the mechanical kinetic energy of the rotating shaft 23 can be converted into electrical energy, which is then stored in a battery via wires, thus conserving energy and utilizing natural potential energy. The purpose of potential energy generation is twofold. After the movable undulating platform 21 rotates, the first spring 15 can be used to drive the movable undulating platform 21 to reset, thereby achieving continuous rotation and generating electricity under the subsequent wave impact effect. During the reset process of the movable undulating platform 21, the ratchet disk 22 and the pawl 231 are in a sliding fit relationship, and the rotating shaft 23 will not rotate in the opposite direction. The connecting plate 232 is used to restrict the connection between the rotating shaft 23 and the ratchet disk 22. That is, the connecting plate 232 is rotatably connected to the inside of the ratchet disk 22, and also serves to support the pawl 231.

[0042] like Figures 1 to 2 As shown, an aluminum alloy bracket 11 is fixed to the top of the buoy platform, and a solar panel 12 is fixed to the side wall of the aluminum alloy bracket 11. The solar panel 12 is electrically connected to a storage battery via wires. The aluminum alloy bracket 11 is located outside the sealed box 13. In order to further utilize natural potential energy to generate electricity during the day, the solar panel 12 is installed to absorb and convert solar energy to generate electricity, which is then converted into electrical energy by a converter and stored in a storage battery to power the probe 5 and the related cloud platform. The cloud platform is used to transmit the information collected by the probe 5.

[0043] like Figures 1 to 2 As shown, an inwardly facing sleeve 131 is fixedly connected to the center of the aforementioned sealing box 13, and the central column 45 passes through the sleeve 131. When the central column 45 undergoes vertical axial displacement, it will extend upward to the sealing box 13. In order to prevent the presence of the sealing box 13 from affecting the displacement of the central column 45, the middle part of the sealing box 13 is set as an inwardly facing sleeve 131, which can extend the movable stroke of the central column 45.

[0044] like Figure 4 , Figures 9-10 As shown, the bottom of the anti-clogging screen cylinder 3 is provided with a base support 31; the central column 45 passes through the center of the base support 31, and the inner diameter of the base support 31 is smaller than the outer diameter of the cleaning brush 47. In order to allow the swing arm 41 to expand to a greater angle when the central column 45 moves relative to the buoy platform body 1, thereby achieving the upward movement of the overall center of the buoy platform, a base support 31 is set at the bottom of the anti-clogging screen cylinder 3. When the central column 45 moves relative to the buoy platform body 1, the central column 45 will drive the swing arm 41 to move together. When the swing arm 41 contacts the base support 31 at the bottom of the anti-clogging screen cylinder 3, it will be squeezed and the collar will move downward relative to the central column 45. After the support arm 44 rotates, the swing arm 41 can be further expanded. In the initial state, the swing arm 41 is located at the bottom of the anti-clogging screen cylinder 3 and does not contact the anti-clogging screen cylinder 3. At the same time, when the central column 45 moves away from the buoy platform body 1 and moves relative, the cleaning brush 47 set on the central column 45 will collide with the base support 31, so that the impurities remaining on the cleaning brush 47 are shaken out of the cleaning brush 47, preventing the cleaning brush 47 from having impurities remaining in its bristles during the intermittent up and down cleaning process and scratching the probe 5.

[0045] Working principle: During the operation of the buoy platform, in addition to being easily deviated from the predetermined test area by the action of waves, when the waves are too large, multiple layers of waves will continuously push the buoy platform away from the predetermined test area, causing the chain between the buoy platform and the anchor to tighten. Under the pushing effect of the waves, the buoy platform will rise and be supported by the waves. After the waves move away, since the center of gravity of the buoy platform is above the water surface, there is a risk of it overturning during the resetting process due to the chain restriction. This may lead to water entering the buoy platform and damaging components that require waterproofing, such as the battery, or even causing the buoy platform to overturn and sink into the water, resulting in the equipment being scrapped.

[0046] To avoid the problem of the buoy platform 1 being pushed up to the center of gravity above the normal water surface when the waves are too large and continuous, which could cause it to flip over upon returning to the water surface due to the high center of gravity, potentially rendering the equipment unusable, this device uses a buoy platform 1 made of high-molecular-weight polyethylene material. This material provides excellent buoyancy, allowing it to float easily on the water surface. After reaching the designated area, the probe 5 is manually submerged to measure various parameters in the water, including COD and dissolved oxygen. To prevent aquatic plants from entangled in the probe 5 and causing data defects, an anti-clogging screen 3 is installed at the bottom of the buoy platform 1 to prevent clogging. The aquatic plants around the screen cylinder 3 are cleared to prevent them from tangling the probe 5. This also prevents the buoy platform 1 from deviating from the normal water surface due to high waves, and to prevent the buoy platform 1 from flipping and sinking during the reset process due to a sudden drop in water level, thus rendering the entire buoy platform unusable. A central column 45 is installed at the center of the buoy platform 1, with a chain and anchor connected to its bottom to limit its position. Furthermore, the central column 45 lowers the overall center of gravity of the equipment, shifting it from the center of the buoy platform 1 to below it. Relying on the buoyancy of the buoy platform 1, the entire buoy platform can still float on the water surface, even in the event of high waves. When the buoy platform 1 is subjected to waves, it will undergo an upward relative displacement. That is, the central column 45 will penetrate downwards through the baffle 16 relative to the buoy platform 1. Because the central column 45 is restrained by the chain and remains in the bottom water, the overall center of gravity of the equipment is lowered. When dealing with wave impact, the chain straightens, and the buoy platform 1 can undergo an upward relative displacement under the impact of the waves. Therefore, it can provide effective balance and stability to the buoy platform 1. Secondly, in order to bring the central column 45 closer to the buoy platform after a large wave has moved away, thereby reducing the risk of the central column 45 hitting the bottom, a second spring 18 is installed between the baffle 16 and the abutment plate 49. The second spring 18 applies an upward force to the top of the central column 45. Under pressure, without external force, i.e. without waves pushing the buoy platform upward, the overall water level drops, and the chain changes from a taut state to a slack state. At this time, the central column 45 will be pushed by the elastic potential energy of the second spring 18 to produce a relative displacement towards the buoy platform body 1, so that the central column 45 is closer to the buoy platform body 1 floating on the water surface, thereby reducing the impact of the central column 45 touching the bottom and causing oscillation that could damage the probe 5 carried on the buoy platform body 1. When waves push the buoy platform body 1 upward, it is subjected to impact force, and the buoy platform body 1 and the central column 45 produce a relative displacement. At this time, the elastic potential energy of the second spring 18 is overcome, which in turn causes a relative displacement between the central column 45 and the buoy platform body 1.

[0047] To further improve the overall stability of the buoy platform when larger waves arrive, multiple swing arms 41 are installed around the bottom of the central column 45. These swing arms 41, along with the counterweight balls 42 at their bases, further lower the overall center of gravity. However, the buoyancy of the buoy platform 1 is still greater than its overall weight. Furthermore, when the waves move away from the buoy platform 1 and the water surface becomes calmer, to prevent the buoy platform 1 from being unable to detect its surrounding area under the influence of small waves due to an excessively low center of gravity (i.e., a reduced detection range), the swing arms 41 initially expand outwards under the pressure of the third spring 46, maintaining contact with the central column 45. A certain angle is maintained, denoted as A. When the central column 45 moves relative to the buoy platform, that is, when the central column 45 moves closer to the buoy platform, the movement of the swing arm 41 is restricted due to the presence of the anti-blocking screen cylinder 3. Consequently, under the connection of the collar, further expansion will occur. At this time, the angle between the central column 45 and the swing arm 41 changes from A to A+B, where B is the angle of the swing arm 41's subsequent expansion. The support arm 44 connects the swing arm 41 and the central column 45, serving as an auxiliary support. When the angle between the swing arm 41 and the central column 45 increases, it will cause the center of gravity of the buoy platform equipment to shift upward. At this time, under the push of small waves, a larger area can be detected within the allowable range under the connection of the chain and anchor.

[0048] Secondly, to achieve cleaning of the probe 5, a cleaning brush 47 is installed on the upper part of the central column 45. This creates relative displacement between the central column 45 and the buoy platform body 1. Specifically, when large waves arrive, the central column 45 can move up and down intermittently. At this time, the central column 45 will cause the cleaning brush 47 to intermittently contact and clean the probe 5. Utilizing the impact force of the waves, in conjunction with the central column 45 and the cleaning brush 47, intermittent cleaning of the probe 5 can be achieved, reducing the frequency of regular maintenance and improving the overall self-maintenance of the buoy platform equipment. To prevent the probe 5 from misaligning or colliding with the cleaning brush 47 during intermittent cleaning, a limiting tube 17 is used to limit the probe 5 at its end. The limiting tube 17 is correspondingly positioned with the cleaning brush 47, ensuring that the probe 5 is precisely positioned during the up-and-down movement of the cleaning brush 47. For cleaning the probe 5 aligned with the axis of the limiting tube 17, the cleaning brush 47 has a U-shaped structure with bristles on its inner side. The bristles can clean the surface of the probe 5 when the axial displacement is vertical. In order to allow the swing arm 41 to expand to a larger angle when the central column 45 moves relative to the buoy platform body 1, thereby realizing the upward movement of the overall center of the buoy platform, a base support 31 is set at the bottom of the anti-clogging screen cylinder 3. The swing arm 41 can be further expanded through the sliding cooperation between the base support 31 and the swing arm 41. At the same time, when the central column 45 moves away from the buoy platform body 1, the cleaning brush 47 set on the central column 45 will collide with the base support 31, so that the impurities remaining on the cleaning brush 47 are shaken out of the cleaning brush 47, preventing impurities from remaining in the bristles of the cleaning brush 47 during the intermittent vertical cleaning process and scratching the probe 5.
