Description

Technical Field

[0001] This application belongs to the field of water quality monitoring technology, specifically relating to a floating monitoring system for water quality monitoring. Background Technology

[0002] In the field of water quality testing, floating monitoring systems are commonly used to monitor the surrounding environment and water quality. This is achieved through water quality sensors on the floating monitoring system. These sensors are high-maintenance-frequency components and are usually located in the middle of the floating monitoring system. However, for large-scale floating monitoring systems, placing the sensors in the middle makes it difficult for maintenance personnel to disassemble and maintain them on the water. Furthermore, large floating monitoring systems are not easily lifted out of the water to shore or a boat for disassembly and maintenance. Therefore, the water quality sensors can be placed at the edge of the floating monitoring system to facilitate disassembly and maintenance on the water. However, placing them at the edge can easily cause the center of gravity of the floating monitoring system to shift, meaning the system cannot maintain its balance in the water.

[0003] To address the aforementioned issues, a balancing device can be added to the edge of the floating monitoring system. Specifically, the balancing device is located on the edge of the floating monitoring system furthest from the water quality sensor, meaning the balancing device and the water quality sensor are symmetrically distributed. However, in actual design, the relative positions of the balancing device and the water quality sensor are not absolutely balanced and symmetrical. Therefore, the problem of the floating monitoring system's center of gravity shifting and affecting its balance still exists. At the same time, this arrangement can also easily lead to an increase in the outer dimensions and overall weight of the floating monitoring system.

[0004] In summary, the floating monitoring systems involved in the relevant technologies have problems such as large external dimensions, large overall weight, and the inability to achieve a balanced setup when monitoring water quality. Summary of the Invention

[0005] This application discloses a floating monitoring system for water quality monitoring, which solves the problems of large external dimensions, large overall weight, and inability to achieve balanced setup when monitoring water quality in related technologies.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A floating monitoring system for water quality monitoring includes:

[0008] A hollow float, with a first through hole on its edge for applying tension, so that the floating monitoring system can move to a preset position;

[0009] A monitoring device is installed in the middle of the floating body. The monitoring device includes a housing, a base and a camera. The housing and the base enclose an installation space. The camera is installed in the installation space and the base is installed on the floating body.

[0010] A photovoltaic module is disposed on the upper surface of the float and surrounds the monitoring device, and the photovoltaic module is inclined upward along the edge of the float in the direction extending toward the central axis of the float.

[0011] A sensor assembly, comprising a sensor, the sensor including at least one of a temperature sensor, a chemical oxygen demand sensor, a nitrate nitrogen sensor, a turbidity sensor, a total organic carbon sensor, a dissolved organic carbon sensor, and a colorimetric sensor;

[0012] The photovoltaic module is electrically connected to the storage battery;

[0013] The float is partially submerged in water, and its edge is provided with symmetrically arranged second through holes and mounting grooves. The sensor assembly is detachably installed in the second through hole, and a portion of the sensor assembly is submerged in water to detect water quality. The battery is installed in the mounting groove.

[0014] The sensor assembly has a first weight A, the battery has a second weight B, the central axis of the float and the sensor assembly have a first distance La, and the central axis of the float and the battery have a second distance Lb.

[0015] The float has a first protrusion that can be immersed in water. The value of A*La-B*Lb is a first value. When the first value is positive, the first protrusion is positioned close to the sensor assembly. When the first value is negative, the first protrusion is positioned close to the battery.

[0016] The technical solution adopted in this application can achieve the following beneficial effects:

[0017] In this application, the first through-hole on the edge of the float allows operators to easily pull or push the floating monitoring system to a preset detection position in the water. The monitoring equipment on the float facilitates observation of the surrounding aquatic environment, the photovoltaic modules on the float improve battery life, and the sensor assembly detects water quality, thus obtaining more detection parameters. Furthermore, since the second through-hole is located on the edge of the float, the sensor assembly is also located on the edge of the float, which facilitates maintenance personnel disassembling and maintaining the sensor assembly from the water. Moreover, because the second through-hole and the mounting slot are symmetrically arranged on the float,… The battery and sensor assembly are symmetrically arranged on the float, and the floating monitoring system is balanced by a first protrusion on the float. Specifically, the first protrusion can be positioned close to the sensor assembly or the battery to center the center of gravity of the floating monitoring system. This means that the buoyancy generated by the portion of the floating monitoring system below the water level is located at the center of the system, balancing gravity and maintaining the system's equilibrium in the water. Furthermore, since both the battery and sensor assembly are housed within the float, the overall size and weight of the floating monitoring system are relatively small. Therefore, the floating monitoring system disclosed in this application solves the problems of large external dimensions, heavy overall weight, and inability to achieve balance when monitoring water quality in related technologies.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The floating monitoring system for water quality monitoring disclosed in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0043] Please refer to Figures 1-19 This application discloses a floating monitoring system for water quality monitoring. The disclosed floating monitoring system includes a float 100, a monitoring device 200, a photovoltaic module 300, a sensor assembly 400, and a battery 500.

[0044] The float 100 has a hollow structure, and the edge of the float 100 is provided with a first through hole 110 for applying tension. The operator can grasp the edge of the float 100 well through the first through hole 110, so that the operator can pull or push the float 100, thereby moving the floating monitoring system to a preset position. The preset position can be the position for detecting water quality, or the position for the operator to disassemble and maintain the floating monitoring system.

[0045] The monitoring device 200 can be used to monitor sewage discharge and ecological changes in the water body surrounding the floating monitoring system. The monitoring device 200 can be installed in the middle of the float 100, i.e., a position far from the edge of the float 100. Alternatively, the monitoring device 200 can be installed at the edge of the float 100. The monitoring device 200 may include a housing 210, a base 220, and a camera 230. The housing 210 and base 220 form an installation space. The camera 230 is located within the installation space, and the base 220 is located on the float 100. In other words, the camera 230 is integrated onto the float 100 through the housing 210 and base 220, and the housing 210 and base 220 protect the camera 230 to ensure its normal operation.

[0046] The photovoltaic module 300 converts solar energy into electrical energy, which is stored in the battery 500. The photovoltaic module 300 is electrically connected to the battery 500, ensuring the normal operation of the floating monitoring system. The photovoltaic module 300 is mounted on the upper surface of the float 100 and surrounds the monitoring device 200. In this configuration, the photovoltaic module 300 surrounds the float 100, with a blank area in the middle of the float 100 to facilitate the installation of the monitoring device 200. Specifically, the photovoltaic module 300 is inclined on the float 100, meaning the upper surface of the float 100 is inclined, and the photovoltaic module 300 is inclined upwards along the edge of the float 100 towards its central axis. This arrangement maximizes the area of ​​the photovoltaic module 300 without changing the circumferential dimensions of the floating monitoring system, thereby improving its endurance. Optionally, the photovoltaic module 300 can be horizontally mounted on the float 100.

[0047] The sensor assembly 400 includes a sensor 410 for detecting water quality. The sensor 410 may include at least one of the following: a temperature sensor, a chemical oxygen demand sensor, a nitrate nitrogen sensor, a turbidity sensor, a total organic carbon sensor, a dissolved organic carbon sensor, a color sensor, a dissolved oxygen detection probe, a pH detection probe, a conductivity detection probe, an oil in water detection probe, a blue-green algae detection probe, a residual chlorine detection probe, a chloride ion detection probe, a salinity detection probe, a fluoride ion detection probe, a redox potential detection probe, a suspended solids detection probe, a chlorophyll a detection probe, an ammonia nitrogen detection probe, a sludge detection probe, and an integrated ammonia nitrogen and nitrate nitrogen detection probe, in order to obtain more detection parameters and improve the detection utilization rate of the floating monitoring system.

[0048] Part of the float 100 can be submerged in water to facilitate the detection of water quality by the floating monitoring system. The float 100 also has symmetrically arranged second through holes 120 and mounting grooves 130 on its edge. That is, the second through holes 120 and mounting grooves 130 are located on both sides of the monitoring device 200. The sensor assembly 400 is detachably installed in the second through hole 120. Specifically, after the sensor assembly 400 is installed in the second through hole 120, it can be detachably installed in the second through hole 120 by the quick-clamp mechanism 670 provided on the float 100. The quick-clamp mechanism 670 can quickly install or remove the sensor assembly 400. Since the sensor assembly 400 is located inside the second through hole 120, part of the sensor assembly 400 can be immersed in water along with part of the float 100 to detect water quality. The battery 500 is located in the mounting groove 130. After part of the float 100 is immersed in water, the mounting groove 130 can prevent water from contacting the battery 500, thereby ensuring that the battery 500 can work normally.

[0049] The sensor assembly 400 has a first weight A, which specifically refers to the weight corresponding to the displacement of the sensor assembly 400. In other words, the total amount of water displaced by the portion of the sensor assembly 400 submerged in water is the displacement of the sensor assembly 400, and the weight of the displaced water is the first weight A. At this time, the float 100 can experience a buoyant force in the water corresponding to the first weight A. The battery 500 has a second weight B, which specifically refers to the weight corresponding to the displacement of the battery 500. At this time, the float 100 can experience a buoyant force in the water corresponding to the second weight B. There is a first distance La between the central axis of the float 100 and the sensor assembly 400, and a second distance Lb between the central axis of the float 100 and the battery 500. Since the monitoring device 200 is located at the central axis of the float 100, there is a first distance La between the sensor assembly 400 and the monitoring device 200, and a second distance Lb between the battery 500 and the monitoring device 200.

[0050] A first protrusion 140 protrudes from the float 100. The first protrusion 140 can be submerged in water along with the float 100. The value A*La-B*Lb can be a first value. When the first value is positive, that is, when A*La-B*Lb is greater than zero, it means that the float 100 is tilted towards the side where the sensor assembly 400 is located. In other words, the center of gravity of the floating monitoring system is biased towards the side of the sensor assembly 400. For details, please refer to [reference needed]. Figure 3 The first protrusion 140 can be positioned close to the sensor assembly 400 to increase the drainage volume on the side of the sensor assembly 400, so as to receive greater buoyancy, in order to counteract the influence of the center of gravity of the floating monitoring system being biased towards the side of the sensor assembly 400, so as to keep the floating monitoring system balanced and stable on the water.

[0051] When the first value is negative, that is, when A*La-B*Lb is less than zero, it means that the float 100 is tilted toward the side where the battery 500 is located, that is, the center of gravity of the floating monitoring system is biased toward the side of the battery 500. At this time, the first protrusion 140 can be set close to the battery 500 to increase the displacement on the side of the battery 500 so that it receives greater buoyancy, in order to counteract the effect of the center of gravity of the floating monitoring system being biased toward the side of the battery 500, so that the floating monitoring system can maintain balance and stability on the water.

[0052] In this application, the first through-hole 110 on the edge of the float 100 facilitates the operation of the floating monitoring system to be moved to the preset detection position in the water by the operator. The monitoring device 200 installed on the float 100 facilitates the observation of the surrounding water environment. The photovoltaic module 300 installed on the float 100 improves the endurance of the battery 500. The sensor assembly 400 can detect water quality, thereby obtaining more detection parameters. At the same time, since the second through-hole 120 is located on the edge of the float 100, the sensor assembly 400 is also located on the edge of the float 100. This facilitates the disassembly and maintenance of the sensor assembly 400 by maintenance personnel on the water. Furthermore, since the second through-hole 120 and the mounting groove 130 are symmetrical on the float 100... Therefore, the battery 500 and sensor assembly 400 are symmetrically arranged on the float 100, and the floating monitoring system is balanced by a first protrusion 140 on the float 100. Specifically, the first protrusion 140 can be positioned close to the sensor assembly 400 or the battery 500 so that the center of gravity of the floating monitoring system is centered. That is, the buoyancy generated by the part of the floating monitoring system below the water level is located at the center of the floating monitoring system, which balances with gravity, thus keeping the floating monitoring system balanced in the water. Furthermore, since the battery 500 and sensor assembly 400 are both located inside the float 100, the floating monitoring system has a small external size and a small overall weight. Therefore, the floating monitoring system disclosed in this application can solve the problems of large external size, large overall weight, and inability to achieve balanced setup when detecting water quality in related technologies.

[0053] Optionally, the float 100 has a second protrusion 150 protruding from the side opposite to the monitoring device 200. The second protrusion 150 is used to support the floating monitoring system when it is placed on the ground. The bottom of the second protrusion 150 needs to protrude from the bottom of the sensor assembly 400 or be flush with the bottom of the sensor assembly 400, so as to prevent the bottom of the sensor assembly 400 from contacting the ground when the floating monitoring system is placed on the ground, thereby preventing the sensor assembly 400 from being damaged.

[0054] Optionally, this application can determine which side of the float 100 the first protrusion 140 is located on using only the first value, that is, whether the first protrusion 140 is located on the side where the sensor assembly 400 is located or on the side where the battery 500 is located.

[0055] In another embodiment, this application can also obtain the distance between the central axis of the float 100 and the first protrusion 140 through a first value, that is, obtain the specific setting position of the first protrusion 140. Specifically, the first protrusion 140 has a third weight C, which specifically refers to the weight corresponding to the displacement of the first protrusion 140 after it is fully submerged in water. In other words, the total amount of water displaced when the first protrusion 140 is fully submerged in water is the displacement of the first protrusion 140, and the weight of this displaced water is the third weight C. At this time, the float 100 can be subjected to buoyancy in the water corresponding to the third weight C, and there is a third distance Lc between the central axis of the float 100 and the first protrusion 140, that is, there is a third distance Lc between the first protrusion 140 and the monitoring device 200. The third weight C and the third distance Lc can be determined by the following formula:

[0056] A*La-B*Lb=C*Lc;

[0057] Where A represents the first weight, La represents the first distance, B represents the second weight, and Lb represents the second distance.

[0058] In this embodiment, not only can the specific side of the float 100 where the first protrusion 140 is located be determined, but also the specific setting position of the first protrusion 140 can be determined after reasonably selecting the weight of the displacement corresponding to the first protrusion 140 after it is immersed in water. That is, the third distance Lc between the central axis of the float 100 and the first protrusion 140 can be determined. At this time, the first protrusion 140 and the float 100 can play the role of a balanced floating monitoring system more stably after being immersed in water.

[0059] Optionally, the first protrusion 140 may be a strip-shaped protrusion. In this case, the first protrusion 140 may be provided only on one side of the sensor assembly 400 or only on one side of the battery 500, that is, only on one side of the sensor assembly 400 or only on one side of the battery 500.

[0060] In another embodiment, the first protrusion 140 is an annular protrusion and is arranged around the sensor assembly 400 or the battery 500. This further increases the water displacement on the side of the sensor assembly 400 or the side of the battery 500, thereby further increasing the buoyancy to further counteract the effect of the center of gravity eccentricity of the floating monitoring system, so that the floating monitoring system can maintain a more balanced and stable position on the water.

[0061] Alternatively, please refer to Figure 4The floating monitoring system may further include a first limiting member 610. When the battery 500 is installed in the mounting slot 130, the first limiting member 610 restricts the vertical movement of the battery 500, preventing it from detaching from the mounting slot 130. Specifically, the first limiting member 610 may be located at the opening of the mounting slot 130 and connected to the float 100 to prevent vertical movement of the battery 500. Optionally, the first limiting member 610 may be detachably connected to the battery 500 via a connector, or the first limiting member 610 may be integrally formed with the battery 500, so that when the first limiting member 610 is connected to the float 100, the battery 500 can be stably positioned within the mounting slot 130. Optionally, the first limiting member 610 may be a sheet metal part.

[0062] Since the first limiting member 610 is only used to limit the movement of the battery 500 in the vertical direction, in order to limit the movement of the battery 500 in the horizontal direction, the floating monitoring system may also include a connecting adhesive. The space between the mounting groove 130 and the battery 500 can be completely filled with the connecting adhesive, and the connecting adhesive can cover the battery 500. At this time, the connecting adhesive can play the role of fixing, sealing and moisture protection, that is, the connecting adhesive can fully protect the battery 500. At the same time, the connecting adhesive can prevent the battery 500 from shaking in the mounting groove 130.

[0063] In another embodiment, the floating monitoring system may further include a second limiting member 620. The side wall of the mounting groove 130 is limited and engaged with the battery 500 by the second limiting member 620. That is, the second limiting member 620 can limit the battery 500. At the same time, when the mounting groove 130 is filled with adhesive, the amount of adhesive used can be reduced due to the presence of the second limiting member 620, which can reduce the overall weight of the floating monitoring system to a certain extent.

[0064] Alternatively, please refer to Figure 10 and Figure 11 The housing 210 is provided with a monitoring window 211, and the camera 230 is opposite to the monitoring window 211 so that the camera 230 can observe the surrounding water environment through the monitoring window 211. The housing 210 must be sealed to the base 220 to prevent water from entering the installation space enclosed by the housing 210 and the base 220. The base 220 can be non-detachably connected to the float 100. For example, the base 220 can be welded or glued to the float 100.

[0065] In another embodiment, the base 220 is detachably connected to the float 100. Specifically, both the edge of the base 220 and the float 100 have mounting holes. The floating monitoring system may also include a first connector 630, one end of which passes through the mounting hole 221 of the base 220 and is detachably connected to the mounting hole of the float 100. In this case, the base 220 can be easily installed on or removed from the float 100, so that the monitoring device 200 can be easily installed on or removed from the float 100 for maintenance. Optionally, the first connector 630 may be a threaded connector, and the mounting hole on the float 100 may be a threaded hole.

[0066] Optionally, the number of cameras 230 can be one, and correspondingly, the number of monitoring windows 211 opened on the housing 210 is also one.

[0067] In another embodiment, there are at least two cameras 230, and correspondingly, there are at least two monitoring windows 211. Each monitoring window 211 is spaced apart on the housing 210, and each monitoring window 211 has a different orientation. Each camera 230 corresponds to each monitoring window 211. In this case, multiple cameras 230 can monitor from different angles at the same time, which makes the monitoring range of the monitoring device 200 larger, thus making it easier to observe sewage discharge, ecological changes, etc. around the water body.

[0068] Optionally, the monitoring device 200 may further include an inner decorative component 250, a light-transmitting lens 260, a lens retainer 270, and an outer decorative component 280 arranged sequentially. The light-transmitting lens 260 is used to seal the monitoring window 211 to prevent dust, water, and other impurities from entering the installation space through the monitoring window 211. The lens retainer 270 is attached to the side of the light-transmitting lens 260 facing away from the camera 230, so that the light-transmitting lens 260 is stably sealed on the monitoring window 211. The outer decorative component 280 and the inner decorative component 250 are located on opposite sides of the light-transmitting lens 260. Specifically, the outer decorative component 280 serves as an outer peripheral component, and the inner decorative component 250 serves as an inner component, with both the outer decorative component 280 and the inner decorative component 250 serving a decorative function. Furthermore, a better sealing effect can be achieved through the assembly of the inner decorative component 250, the light-transmitting lens 260, the lens retainer 270, and the outer decorative component 280.

[0069] In this embodiment, to improve the shooting effect of the camera 230, the monitoring device 200 may further include a supplementary light 240. The supplementary light 240 is positioned close to the camera 230; in other words, the supplementary light 240 and the camera 230 can be arranged side by side so that the supplementary light 240 can provide supplementary lighting to the object being photographed by the camera 230, thereby ensuring that the object captured by the camera 230 is clearer. Of course, the monitoring device 200 may not include the supplementary light 240.

[0070] Optionally, the floating monitoring system may also include a warning light 640 and a weather sensor 650. The housing 210 has a first expansion interface 212. Specifically, the first expansion interface 212 is located on the top of the housing 210. The warning light 640 is positioned at the first expansion interface 212, and the weather sensor 650 is positioned above the warning light 640. The warning light 640 and the weather sensor 650 can be electrically connected to the first expansion interface 212 to ensure their normal operation. Thus, the warning light 640 and the weather sensor 650 are integrated into the monitoring device 200, further maximizing the space on the float 100 and making the floating monitoring system more compact, thereby increasing its integration level. Meanwhile, since the warning light 640 is specifically used to remind surrounding vessels to maintain a certain distance from the floating monitoring system to prevent collisions, and the weather sensor 650 can detect the weather conditions of the environment in which the floating monitoring system is located, such as the surrounding wind force, this broadens the detection range and applicability of the floating monitoring system. Of course, the floating monitoring system may also be without the warning light 640 and the weather sensor 650, or may only have one of them.

[0071] Optionally, other types of expansion devices may also be installed on the first expansion interface 212, and this application embodiment does not impose specific limitations on this.

[0072] Optionally, a second expansion interface 213 may also be provided on the housing 210. Specifically, the second expansion interface 213 is provided on the side of the housing 210. The second expansion interface 213 and the monitoring window 211 may be located on the same surface of the housing 210. A memory card may be inserted into the second expansion interface 213 to store images captured by the camera 230. The second expansion interface 213 may also be other interfaces used for debugging. To prevent impurities from entering the second expansion interface 213, an interface cover 290 is detachably provided at the second expansion interface 213. The interface cover 290 is used to cover the second expansion interface 213, thereby protecting the second expansion interface 213.

[0073] Alternatively, please refer to Figure 1The photovoltaic module 300 may include at least two photovoltaic panels, which are spaced apart and electrically connected to the battery 500. The photovoltaic panels include a first photovoltaic panel 310 and a second photovoltaic panel 320. The first photovoltaic panel 310 may cover the second through-hole 120, thereby covering the sensor assembly 400. The second photovoltaic panel 320 may cover the mounting groove 130, thereby covering the battery 500. To facilitate disassembly and maintenance of the sensor assembly 400, the first photovoltaic panel 310 needs to be detachably mounted on the float 100, or the first photovoltaic panel 310 needs to be rotatably disposed on the float 100, so as to facilitate opening the first photovoltaic panel 310 for disassembly and maintenance of the sensor assembly 400. For details, please refer to... Figures 13 to 15 The first photovoltaic panel 310 may include a solar panel 312, which is rotatably disposed on the float 100.

[0074] In another embodiment, the solar panel 312 is generally made of aluminum and is relatively thin. Therefore, repeated rotation of the solar panel 312 will damage it. In this case, the first photovoltaic panel 310 may also include a support plate 311 connected to the solar panel 312. The support plate 311 supports the solar panel 312 and can improve the structural strength of the first photovoltaic panel 310, that is, protect the solar panel 312 and prevent it from being damaged. In this embodiment, the support plate 311 can be rotatably mounted on the float 100 via a hinge mechanism 315. Specifically, the hinge mechanism 315 is detachably connected to the base 220 mentioned above via a third connector 660, so that the hinge mechanism 315 is mounted on the float 100 via the base 220.

[0075] Optionally, the number of hinge mechanisms 315 can be at least two, with multiple hinge mechanisms 315 spaced apart on the support plate 311 to ensure the rotational stability of the support plate 311.

[0076] Optionally, the support plate 311 is not provided with the support rod 313 described below. During the process of disassembling and repairing the sensor assembly 400, or during the process of installing the sensor assembly 400, the operator can always hold the support plate 311 to disassemble or install the sensor assembly 400.

[0077] In another embodiment, a support rod 313 is rotatably provided on the side of the support plate 311 opposite to the solar panel 312. When the first photovoltaic panel 310 is opened, i.e., when the support plate 311 is rotated, the first photovoltaic panel 310 rotates open by a certain angle, allowing the support rod 313 to rotate to contact the float 100 to support the first photovoltaic panel 310. At this time, the operator can disassemble or install the sensor assembly 400. After disassembling or installing the sensor assembly 400, i.e., during the process of closing the first photovoltaic panel 310, the operator can pull the support rod 313 to drive the support plate 311 back to its original position, thereby restoring the first photovoltaic panel 310 to its original position to cover the second through hole 120. At this time, the support rod 313 can be reset. Thus, the support plate 311 facilitates the operator's disassembly or installation of the sensor assembly 400 and facilitates the operator's closure of the first photovoltaic panel 310.

[0078] Optionally, when the first photovoltaic panel 310 is closed, in order to prevent the first photovoltaic panel 310 from being accidentally opened during the operation of the floating monitoring system, the first photovoltaic panel 310 can be locked with the float 100 through the locking mechanism 314 to ensure the stability of the engagement between the first photovoltaic panel 310 and the float 100.

[0079] Optionally, the first photovoltaic panel 310 may also include a seal 318, which is disposed around the support plate 311. When the first photovoltaic panel 310 is closed, the seal 318 is sealed to the float 100 to ensure the sealing of the first photovoltaic panel 310 and the float 100.

[0080] Optionally, the first photovoltaic panel 310 may also include a second connector 316, and the solar panel 312 and the support plate 311 may be detachably connected directly through the second connector 316, which may specifically be a threaded connector.

[0081] In another embodiment, the first photovoltaic panel 310 may further include a connecting plate 317, which is attached to the edge of the solar panel 312 to avoid shading a large area of ​​the solar panel 312. The second connector 316 can pass through the connecting plate 317 and the solar panel 312 in sequence and is detachably connected to the support plate 311. That is, at this time, the connecting plate 317 is sandwiched between the end of the second connector 316 and the solar panel 312, which makes the connection stress on the solar panel 312 less concentrated, thereby avoiding excessive damage to the solar panel 312. Moreover, the second connector 316 and the connecting plate 317 can improve the overall connection strength of the first photovoltaic panel 310.

[0082] Alternatively, other photovoltaic panels of the photovoltaic module 300 can also be detachably connected to the float 100 via the second connector 316 and the connecting plate 317.

[0083] Optionally, the first photovoltaic panel 310 and the second photovoltaic panel 320 of the photovoltaic module 300 can be designed as polygonal irregular shapes so that the photovoltaic module 300 occupies as much of the upper surface of the floating body 100 as possible. In this case, the photovoltaic module 300 has a larger area, which means that this arrangement has the highest area utilization rate. At the same time, the design tilt angle of the first photovoltaic panel 310 and the second photovoltaic panel 320 can be reduced, thereby reducing the overall height of the floating monitoring system, that is, lowering the center of gravity of the floating monitoring system, thereby improving the stability of the floating monitoring system.

[0084] Alternatively, please refer to Figures 16 to 19 The sensor assembly 400 may also include a protective cover 420, a mounting bracket 430, and a handle 440. The sensor 410 is detachably mounted on the mounting bracket 430. Specifically, the mounting bracket 430 may have a plurality of threaded holes 431 spaced apart. The plurality of sensors 410 may correspond one-to-one with the plurality of threaded holes 431 and be threadedly engaged. The mounting bracket 430 is detachably mounted inside the protective cover 420 so that part of the sensor 410 is mounted inside the protective cover 420. At this time, the protective cover 420 can protect the sensor 410. The protective cover 420 has a water inlet hole 421, that is, water can enter the protective cover 420 through the water inlet hole 421 so that the sensor 410 can detect water quality. The handle 440 may include a gripping part 441, a rotating shaft 442, and a limiting part 443 that are bent relative to each other and connected in sequence. The mounting bracket 430 has a first mating hole, and the protective cover 420 has a second mating hole 422. The handle 440 is rotatably disposed in the first mating hole and the second mating hole 422 via the rotating shaft 442. That is, the handle 440 can rotate relative to the protective cover 420 and the mounting bracket 430, and the handle 440 can always be limited and engaged with the protective cover 420 during rotation, so that when the operator grips the gripping part 441 and applies force, the entire sensor assembly 400 can be moved.

[0085] In another embodiment, when the handle 440 is rotated to the first position, i.e. when the handle 440 is picked up, the limiting part 443 can engage with the protective cover 420 in the vertical direction. At this time, the protective cover 420, the mounting bracket 430, and the sensor 410 can be taken out simultaneously through the handle 440, so as to facilitate the operator to maintain the sensor assembly 400. When the handle 440 is rotated to the second position, i.e. when the handle 440 is put down, the limiting part 443 is released from the limiting engagement with the protective cover 420, so that the protective cover 420 and the mounting bracket 430 can be separated. At this time, the operator can remove the protective cover 420 separately to clean the impurities inside the protective cover 420, thereby preventing the impurities inside the protective cover 420 from affecting the normal operation of the sensor 410. At the same time, the sensor 410 can be disassembled and maintained or additional sensors 410 can be added.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
