Description

Technical Field

[0001] This invention relates to the field of hydrological and meteorological observation technology, and more particularly to the field of hydrological monitoring buoy technology, specifically a hydrological and meteorological observation instrument and its deployment device. Background Technology

[0002] A hydrological buoy is a device used for hydrological monitoring. It typically floats on the water's surface and can be carried by a ship. It measures and transmits hydrological information in real time, including water level, current velocity, current direction, water temperature, and water quality. A launching and deploying device is used to accurately deploy the hydrological buoy to the target water area. For example, patent CN 209441554 U discloses a hydro-meteorological observation instrument, including a buoy body, a balancing body connected to the bottom of the buoy body, a stabilizing ring fitted around the buoy body, a rope connecting the inner wall of the stabilizing ring to the outer wall of the buoy body, a protective sleeve fitted over the upper surface of the buoy body, multiple mounting rods connected to the upper surface of the buoy body, a mounting plate at the intersection of the tops of all the mounting rods, a temperature and humidity sensor mounted on the bottom surface of the mounting plate, a lightning rod mounted on the surface of the mounting plate, a current meter mounted at the bottom of the balancing body, solar panels mounted between the mounting rods, a circuit board inside the buoy body, and navigation lights mounted on the mounting rods. This utility model's observation instrument has a buoyant buoyancy, enabling observation in different water areas. Through special modifications to the buoy body, the stability of the buoy body on the water surface can be maximized. The use of lightning rods for lightning protection ensures normal observation during thunderstorms and provides good protection for the instrument. For example, patent CN 221068394 U discloses a hydrological monitoring buoy deployment device, including a deployment slide. The deployment slide is inclined and has a hollow structure. Several buoys are loaded in the deployment slide, and the buoys are in contact with each other. A connecting lug is fixedly connected to the bottom of the deployment slide. A through groove is opened on the side of the deployment slide, and a fixing plate is fixedly connected to the side of the deployment slide. A main wheel is movably connected to the lower end of the fixing plate. A secondary wheel is fixedly connected to the bottom of the main wheel. Four stop rods are fixedly connected to the outer surface of the secondary wheel, with two of the stop rods jointly positioning one buoy. Through the coordinated arrangement of the deployment slide, buoys, through groove, main wheel, secondary wheel, stop rods, groove, locking block, locking handle, connecting rod, and tension spring, multiple buoys can be pre-loaded and single buoys can be deployed sequentially, resulting in very high deployment efficiency and simple on-site operation. However, based on the current practical use of hydrological buoys and deployment devices, certain drawbacks still exist, such as: 1. Hydrological buoys are subject to significant displacement due to water flow, which can easily lead to collision damage and affect their use in hydrological monitoring. 2. Conventional hydrological buoys have a fixed structure and a stable center of gravity. They cannot be adjusted to lower their center of gravity. When used in complex water environments, they may capsize due to wind and waves, and they are not easy to automatically right themselves, which can easily cause damage. 3. When the buoy is used on the water surface, it cannot automatically drive away birds. Its shell will be damaged by birds trampling, scratching, or even droppings. In addition, water erosion will cause damage. 4. When deploying buoys, they are basically thrown into the water by hand. For waters far from the shore, they are carried and deployed by simple boats. However, when deploying buoys in shallow waters, it is not convenient to ensure long-distance deployment for monitoring. Therefore, we propose a hydro-meteorological observation instrument and its deployment device to solve the problems mentioned above. Summary of the Invention

[0003] The purpose of this invention is to provide a hydro-meteorological observation instrument and its deployment device to solve the problems mentioned in the background art, such as the buoys of the current hydro-meteorological observation instruments and their deployment devices being easily damaged by large displacement, overturning, or being trampled by birds, which affects long-term stable monitoring and use, and the deployment device being inconvenient for long-distance deployment of buoys in shallow water.

The bottom of the second limiting rod is rotatably installed on the top surface of the sealing plate. A second spring is sleeved on the outer side of the bottom of the vertical rod and connected to the bottom of the sealing plate.

[0007] Furthermore: the counterweight mechanism includes a second fixed cylinder and a counterweight block. The second fixed cylinder is integrally fixedly installed in the middle of the bottom end of the lower housing. A through hole is opened on the outer side of the middle of the second fixed cylinder.

[0008] Furthermore, the bottom surface of the lower housing is provided with a buffer plate at equal angles. The buffer plate has an arc-shaped triangular structure, and the inner side of the buffer plate is integrally fixed with the counterweight mechanism.

[0009] Furthermore: the upper outer edge and the lower outer edge are both inclined on the outer side of the upper shell and the lower shell, and an upper magnetic ring and a lower magnetic ring are respectively provided on the outer side of the upper outer edge and the lower outer edge, and a reflective strip is attached to the top surface of the upper magnetic ring at an equal angle.

[0010] Furthermore, the protective pad includes a first protective pad and a second protective pad, which are respectively disposed on the inner sides of the upper outer edge and the lower outer edge, and the contact surfaces of the first protective pad and the second protective pad are sealed together.

[0011] Furthermore: the protective pad includes a third protective pad, which is disposed between the upper outer edge and the lower outer edge, and the outer side of the third protective pad has a groove with a spiral structure.

[0012] The present invention also provides the following technical solution: a launching and deployment device for a hydro-meteorological observation instrument, the launching and deployment device comprising an integrally fixed support frame, a mounting plate and a drive frame, the mounting plate being symmetrically arranged on both sides of the top of the support frame, the drive frame being symmetrically fixed at the upper and lower ends of the mounting plate, the drive frame having a drive shaft rotatably mounted on both ends of the inner side of the drive frame, a transmission belt being drivenly connected to the outer side of the drive shaft, and a magnetic plate fixed inside the drive frame being arranged on the inner side of the transmission belt, the magnetic plate being in contact with the bottom of the transmission belt.

[0013] Furthermore: a second sliding groove is provided at the middle of the end of the mounting plate, a second slider is slidably connected inside the second sliding groove, a second sliding rod is fixedly installed in the middle of the second sliding groove, the second slider is slidably installed on the outside of the second sliding rod, a third spring is connected to the outside of the second slider and sleeved on the outside of the second sliding rod, and a buffer rod is horizontally arranged between the mounting plates and connected to the inside of the second sliding groove.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: the hydro-meteorological observation instrument and its deployment device can effectively reduce displacement caused by wind and waves, enhance stability by adjusting and lowering the center of gravity, automatically drive away birds, ensure stable monitoring and use of the buoy, and the deployment device is convenient for deploying the buoy at a distance in shallow water. 1. This solution includes an upper housing, a top cover, a bottom plate, a battery, and a mounting frame. The upper housing, top cover, and bottom plate form a closed cavity to facilitate the installation of the battery and mounting frame, and to assemble and use the monitoring elements, so that it can be placed in water for hydrological monitoring. 2. This solution includes a first sliding groove, a first sliding rod, a fixed plate, a first sliding block, and a photovoltaic panel. The fixed plate forms a sliding structure on the outside of the first sliding rod through the first sliding block. When a bird steps on it, the fixed plate automatically slides down due to the bird's own weight, thus scaring the bird away. The fixed plate is also equipped with a photovoltaic panel to facilitate the conversion of light energy. 3. This design includes an upper outer edge, an upper magnetic ring, a lower outer edge, and a lower magnetic ring. The upper and lower outer edges protrude outwards at the ends of the upper and lower housings, which enhances the structural strength of the upper and lower housings and facilitates the installation of the upper and lower magnetic rings, making it easier to use with the launch and delivery device. 4. This solution includes a buffer plate, which is set at an angle on the bottom surface of the lower shell. Through the arc-shaped structure of the buffer plate, when encountering wind, waves and water flow, the water flow can drive it to rotate, thereby dissipating the force and reducing the displacement caused by wind, waves and water flow. 5. This design includes a first fixed cylinder, a sleeve, a counterweight, and a fixed rod. When the buoy enters the water, the buoyancy of the water causes the vertical rod to move upward, causing the first and second limiting rods to lose their engagement with the limiting top plate. This allows the counterweight, fixed rod, and limiting top plate to slide down inside the sleeve, thereby extending the counterweight, lowering the overall center of gravity of the buoy, and enhancing its stability. 6. This solution includes a second fixed cylinder, a telescopic rod, and a counterweight. When the buoy enters the water, water enters the interior of the second fixed cylinder. The liquid level sensor detects the water and transmits a signal to the controller. The controller then controls the telescopic rod to extend or retract, thereby raising or lowering the counterweight and adjusting the center of gravity. 7. This solution includes a first protective pad and a second protective pad. The ends of the first and second protective pads are respectively attached to the inner sides of the upper and lower outer edges. The tight fit between the first and second protective pads facilitates collision protection for the buoy during use. 8. This solution includes a third protective pad and a groove. When the buoy rotates due to wind and waves, the spiral structure of the groove can drive the buoy to rise and fall in the water, thereby converting the thrust of the wind and waves into a spiral tangential force and reducing displacement. 9. This solution includes a drive frame, a conveyor belt, and a magnetic plate. The buoy is placed inside the launching device by magnetic attraction between the magnetic plate and the upper and lower magnetic rings. The buoy is launched after the magnetic attraction between the upper outer edge and the lower magnetic ring and the magnetic plate is lost, thanks to the transmission drive of the conveyor belt. 10. This design includes a second chute, a second slider, a third spring, and a buffer rod. The buffer rod helps to cushion the placed buoy, and the buoy squeezes and slides the buffer rod and the second slider inside the second chute, which is facilitated by the elastic release of the third spring, increasing the initial velocity of the buoy during deployment and thus increasing the deployment distance.

[0018] Please see Figures 1-11 The present invention provides the following technical solution: A hydrometeorological observation instrument includes: an upper housing 1, an upper outer edge 101, an upper magnetic ring 102, a reflective strip 103, a sealing ring 104, a top cover 2, a first sliding groove 201, a first sliding rod 202, a first spring 203, a hole cover 204, a wire hole 205, a slot 206, a fixing plate 3, a first slider 301, a photovoltaic panel 302, a base plate 4, a battery 5, a mounting frame 6, a fixing bracket 601, a lower housing 7, a lower outer edge 701, a lower magnetic ring 702, a buffer plate 703, a first fixing cylinder 8, a through hole 801, a sealing plate 802, a sleeve 803, a vertical rod 804, and a float. 805, First limiting rod; 806, Second limiting rod; 807, Second spring; 808, Second fixed cylinder; 81, Liquid level sensor; 8101, Controller; 8102, Telescopic rod; 8103, Counterweight; 9, Fixed rod; 901, Limiting top plate; 902, First protective pad; 10, Second protective pad; 11, Third protective pad; 12, Groove; 1201, Support frame; 13, Mounting plate; 14, Drive frame; 15, Drive shaft; 1501, Transmission belt; 1502, Magnetic plate; 1503, Second slide groove; 16, Second slider; 1601, Second slide rod; 1602, Third spring; and 17, Buffer rod. The upper housing 1 is equipped with a detection element inside. The top cover 2 has a hemispherical structure. The bottom end of the top cover 2 is threadedly fixed to the upper housing 1. A sealing ring 104 is provided between the upper housing 1 and the top cover 2. The fixing plate 3 is slidably installed above the top cover 2. A photovoltaic panel 302 is attached to the surface of the fixing plate 3. The bottom plate 4 is sealed and fixedly connected to the bottom end of the upper housing 1. A storage battery 5 is provided on the surface of the bottom plate 4. An installation frame 6 is provided above the storage battery 5. The lower housing 7 is connected to the bottom of the upper housing 1. A downward telescopic counterweight mechanism is provided inside the lower housing 7. The upper shell 1 and the lower shell 7 are respectively integrally provided with an upper outer extension edge 101 and a lower outer extension edge 701 at their ends. Magnetic elements are provided on the outer sides of the upper outer extension edge 101 and the lower outer extension edge 701 to assist in delivery and retrieval. Protective pads are provided on the inner sides of the upper outer extension edge 101 and the lower outer extension edge 701. The upper outer extension edge 101 and the lower outer extension edge 701 are both inclined on the outer sides of the upper shell 1 and the lower shell 7. An upper magnetic ring 102 and a lower magnetic ring 702 are respectively provided on the outer sides of the upper outer extension edge 101 and the lower outer extension edge 701. A reflective strip 103 is attached to the top surface of the upper magnetic ring 102 at equal angles.

[0019] The above technical solution involves connecting the upper shell 1, top cover 2, and bottom plate 4 to form a sealed cavity, facilitating the installation of the battery 5 and mounting frame 6. The mounting frame 6 is fixed above the bottom plate 4 by a fixing bracket 601, which also limits and fixes the battery 5. A photovoltaic panel 302 on the outside of the fixing plate 3 facilitates continuous power conversion, ensuring long-term hydrological monitoring. A counterweight mechanism at the bottom of the lower shell 7 lowers the buoy's center of gravity after it enters the water, enhancing its stability. Protective pads on the outside of the upper shell 1 and lower shell 7 ensure stable protection during use, guaranteeing long-term use. The upper magnetic ring 102 and lower magnetic ring 702 fixed on the outside of the upper shell 1 and lower shell 7 can be used for deployment. During retrieval, magnetic floatable components can be remotely launched. By pulling with a cable, the floatable components are attracted to the upper magnetic ring 102 or lower magnetic ring 702, allowing the buoy to be pulled back for recovery.

[0020] Among them: such as Figure 2 , Figure 3 , Figure 4 and Figure 6 In the top cover 2, a first sliding groove 201 is provided at equal angles on the outer side of the top. A first sliding rod 202 is fixedly installed in the middle of the first sliding groove 201. A first slider 301 is fixedly installed in the middle of the bottom surface of the fixing plate 3. The fixing plate 3 is slidably connected to the outer side of the first sliding rod 202 through the first slider 301. A first spring 203 is connected to the outer side of the first slider 301 and sleeved on the outer side of the first sliding rod 202. The centers of the top cover 2, the first sliding rod 202, the fixing plate 3 and the first slider 301 are located at the same point. A hole cover 204 is installed in the middle of the top of the top cover 2. A hollow groove 206 is provided on the bottom side of the hole cover 204. A wire hole 205 communicating with the top of the first sliding groove 201 is connected to the outer side of the hollow groove 206.

[0021] The above technical solution is adopted: the fixed plate 3 is slidably connected to the outside of the first slide rod 202 through the first slider 301. When the bird steps on it, the fixed plate 3 slides down due to the bird's gravity, which can scare the bird away. The fixed plate 3 is reset by the elastic action of the first spring 203. The design of the center of the top cover 2, the first slide rod 202, the fixed plate 3 and the first slider 301 being located at the same point ensures that the sliding trajectory of the fixed plate 3 is a concentric circle with the center of the top cover 2, which can avoid jamming and collision. The wiring is connected through the wire hole 205 opened at the top of the first slide groove 201, and the top of the top cover 2 is sealed by the hole cover 204.

[0022] Among them: such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8In the middle, the counterweight mechanism includes a first fixed cylinder 8 and a counterweight block 9. The first fixed cylinder 8 is integrally fixedly installed in the middle of the bottom end of the lower housing 7. The counterweight block 9 is located at the bottom inner side of the first fixed cylinder 8. A through hole 801 is opened on the outer side of the middle part of the first fixed cylinder 8. A sealing plate 802 is fixedly installed at the top of the first fixed cylinder 8. A sleeve 803 is integrally fixed to the sealing plate 802. A fixed rod 901 is telescopically connected inside the sleeve 803. The counterweight block 9 is fixedly connected to the bottom end of the fixed rod 901. A limiting top plate 902 is connected to the top of the fixed rod 901. A locking block protrudes symmetrically outward from the side of the limiting top plate 902 and slides up and down connected to the sleeve 803. Inside the sealing plate 802, vertical rods 804 are symmetrically slidably connected up and down. A float 805 is fixedly installed at the bottom end of the vertical rod 804. A first limiting rod 806 is rotatably connected to the inner side of the top end of the vertical rod 804. A second limiting rod 807 is rotatably connected to the bottom end of the first limiting rod 806. The bottom end of the second limiting rod 807 is rotatably installed on the top surface of the sealing plate 802. A second spring 808 connected to the bottom of the sealing plate 802 is sleeved on the outer side of the bottom of the vertical rod 804. A buffer plate 703 is provided at equal angles on the bottom surface of the lower housing 7. The buffer plate 703 has an arc-shaped triangular structure. The inner side of the buffer plate 703 is integrally fixed with the first fixed cylinder 8.

[0023] The above technical solution enables the buoy to automatically slide the float 805 and vertical rod 804 upwards by the buoyancy of the water after the buoy enters the water. This causes the first limiting rod 806 and the second limiting rod 807 to rotate, losing their locking and limiting effect on the limiting top plate 902. This allows the fixing rod 901 and the counterweight 9 to automatically slide down inside the sleeve 803, thereby adjusting and lowering the overall center of gravity of the buoy, maintaining and increasing its stability. It can also automatically right itself when it overturns. Furthermore, the buffer plate 703 is fixed between the outer side of the first fixing cylinder 8 and the bottom surface of the lower shell 7. Through its arc-shaped structure, it can dissipate the impact force of wind and waves by rotation, thereby reducing its lateral displacement and increasing its protective performance.

[0024] Among them, such as Figure 9 and Figure 10 In the middle, the counterweight mechanism includes a second fixed cylinder 81 and a counterweight block 9. The second fixed cylinder 81 is integrally fixedly installed in the middle of the bottom end of the lower housing 7. A through hole 801 is opened on the outer side of the middle part of the second fixed cylinder 81. A telescopic rod 8103 is fixedly installed inside the second fixed cylinder 81. The bottom end of the telescopic rod 8103 is fixedly connected to the counterweight block 9. A liquid level sensor 8101 is installed on the top surface inside the second fixed cylinder 81, and a controller 8102 is provided on the top surface of the second fixed cylinder 81.

[0025] The above technical solution is adopted: the second fixed cylinder 81 replaces the original first fixed cylinder 8. After entering the water, the liquid level sensor 8101 detects the water entry, and the controller 8102 controls the extension of the telescopic rod 8103 to adjust the height of the counterweight 9, thereby adjusting the center of gravity position, which facilitates automatic control.

[0026] Among them: such as Figure 2 , Figure 3 and Figure 4 In the middle, the protective pad includes a first protective pad 10 and a second protective pad 11. The first protective pad 10 and the second protective pad 11 are respectively disposed on the inner side of the upper outer extension edge 101 and the lower outer extension edge 701, and the contact surfaces of the first protective pad 10 and the second protective pad 11 are sealed and fitted together.

[0027] The above technical solution is adopted: after the upper shell 1 and the lower shell 7 are connected and fixed, the first protective pad 10 and the second protective pad 11 are attached to the outside of the upper shell 1 and the lower shell 7, so that the buoy can be used for external protection when it is in use.

[0028] Among them: such as Figure 11 In the middle, the protective pad includes a third protective pad 12, which is disposed between the upper outer extension 101 and the lower outer extension 701. The outer side of the third protective pad 12 has a groove 1201 with a spiral structure.

[0029] The above technical solution is adopted: the third protective pad 12 is set around the outside of the upper shell 1 and the lower shell 7 to provide protection. At the same time, when the buoy rotates due to the impact of wind and waves, the spiral structure of the groove 1201 can make the buoy rise and fall in the water, thereby eliminating the thrust, further reducing displacement, and ensuring monitoring and use within the predetermined area.

[0030] Please see Figure 1 and Figures 12-14 The present invention provides the following technical solution: A launching and deployment device for a hydro-meteorological observation instrument includes: a support frame 13, a mounting plate 14, a drive frame 15, a drive shaft 1501, a transmission belt 1502, a magnetic plate 1503, a second slide 16, a second slider 1601, a second slide rod 1602, a third spring 1603, and a buffer rod 17. The mounting plate 14 is symmetrically arranged on both sides of the top of the support frame 13. The drive frame 15 is symmetrically fixed at the upper and lower ends of the mounting plate 14. The drive shaft 1501 is rotatably mounted on both ends of the inner side of the drive frame 15. The drive shaft 1501 is connected to the outer side of the drive belt 1502. The magnetic plate 1503 is fixed inside the drive frame 15 on the inner side of the drive belt 1502. The magnetic plate 1503 is in contact with the bottom of the drive belt 1502. The middle of the end of the mounting plate 14 is provided with a second slide groove 16. The second slider 1601 is slidably connected inside the second slide groove 16. The middle of the second slide groove 16 is fixedly installed with a second slide rod 1602. The second slider 1601 is slidably installed on the outer side of the second slide rod 1602. The outer side of the second slider 1601 is connected with a third spring 1603 sleeved on the outer side of the second slide rod 1602. The inner side of the second slide groove 16 is connected with a buffer rod 17 that is transversely arranged between the mounting plates 14.

[0031] The above technical solution involves filling the buoy into the space between the drive frame 15, which allows the magnetic plate 1503 to magnetically attract the upper magnetic ring 102 and the lower magnetic ring 702 between the transmission belt 1502 and the magnetic plate 1503. Through the transmission belt 1502, the buoy can slide outward. When the magnetic connection between the transmission belt 1502 and the upper magnetic ring 102 and the lower magnetic ring 702 is lost, the buoy can be launched and thrown out by inertia. Furthermore, the elastic sliding of the second slider 1601 inside the second slide groove 16 and the obstruction of the buffer rod 17 can buffer the filling of the buoy. The buoy squeezes the buffer rod 17 and the second slide groove 16. During the launch, the elastic potential energy of the third spring 1603 can increase the initial launch speed of the buoy, thereby increasing the casting distance. This makes it more suitable for use in shallow water areas where it is not suitable to enter. Example 1

[0032] The bottom of the support frame 13 is assembled onto a hydrological detection device used for water navigation, such as a trimaran. An adjustable base that can be raised, rotated, and spun can be installed on the bottom to adjust the angle and orientation of the support frame 13, so as to adjust the launch and release position. First, the buoy is placed from the top of the drive frame 15 toward the inside of the drive frame 15. During placement, the upper magnetic ring 102 and the lower magnetic ring 702 provided on the outer side of the upper housing 1 and the lower housing 7 are in contact with the transmission belt 1502 on the inside of the drive frame 15, so that the upper magnetic ring 102 and the lower magnetic ring 702 are magnetically attracted to the magnetic plate 1503 with the transmission belt 1502 in between. The external drive shaft 1501 drives the transmission belt 1502 to drive, and the friction between the transmission belt 1502 and the lower magnetic ring 702 and the upper magnetic ring 102 is used to bring the buoy to the inside of the end of the drive frame 15. The drive conveyor belt 1502 is reversed. Through the magnetic attraction between the upper magnetic ring 102 and the lower magnetic ring 702 and the magnetic plate 1503, when the conveyor belt 1502 is reversed, it can drive the buoy to slide stably outward on the inside of the drive frame 15. When the buoy slides to the top of the drive frame 15, the upper magnetic ring 102 and the lower magnetic ring 702 are disengaged from the magnetic plate 1503 at the top of the drive frame 15. Under the action of inertia, the buoy is launched outward from the inside of the drive frame 15 by the conveyor belt 1502. Meanwhile, when the buoy is placed inside the drive frame 15, its bottom contacts the buffer rod 17 first, which can prevent the buoy from falling. The end of the buffer rod 17 is fixed inside the second slider 1601. The second slider 1601 forms an elastic structure outside the second slider 1602 through the third spring 1603, which can buffer the placement of the buoy. By squeezing the buoy toward the end of the drive frame 15, the third spring 1603 is compressed. When the buoy is deployed, the elastic potential energy of the third spring 1603 is released, which can increase the initial speed of the buoy launch and deployment, so as to ensure long-distance deployment. After the buoy is deployed to the designated area, its center of gravity is low, causing the bottom of the lower housing 7 to sink into the water. Simultaneously, a through hole 801 is provided in the middle of the first fixing cylinder 8, which is integrally fixed to the bottom of the lower housing 7. Water enters the interior of the first fixing cylinder 8 through the through hole 801. Under the buoyancy of the water, the float 805 causes the vertical rod 804 to slide up and down on both sides of the sealing plate 802. When the vertical rod 804 slides upward, it causes the top of the first limiting rod 806 to move upward, and through the vertical rod 804, the first limiting rod 806, and the second limiting rod 807... The sequential hinge between the sealing plate 802 and the first limiting rod 806 and the second limiting rod 807 increases the angle between them, and their connecting nodes move to the outside of the sleeve 803. This causes the nodes of the first limiting rod 806 and the second limiting rod 807 to lose their limiting effect on the bottom of the limiting top plate 902. This facilitates the sliding of the limiting top plate 902 and the fixing rod 901 downward inside the sleeve 803 by the weight of the counterweight 9, so as to ensure that the counterweight 9 extends downward inside the first fixing cylinder 8, lowers the overall center of gravity of the buoy, and increases the overall stability of the buoy. When the buoy is in use, the upper part of the upper shell 1 is exposed above the water surface. The upper outer edge 101 integrally formed on the top side of the upper shell 1, after the upper magnetic ring 102 is fixed, reflective strips 103 are attached to the surface of the upper magnetic ring 102 at equal angles to provide reflective indication. Meanwhile, a fixing plate 3 is provided on the outer side of the top cover 2. A photovoltaic panel 302 is installed on the fixing plate 3. The photovoltaic panel 302 can ensure the energy supply for long-term hydrological monitoring. The bottom surface of the fixing plate 3 is slidably connected to the inside of the first sliding groove 201 opened on the top surface of the top cover 2 through an integrally set first slider 301. A first sliding rod 202 is fixed inside the first sliding groove 201 to slide the first slider 301. A first spring 203 is sleeved on the outside of the first sliding rod 202 and connected to the outside of the first slider 301 to maintain the unstable installation of the fixing plate 3. When the fixing plate 3 is stepped on by birds, it will automatically slide downward to drive away birds through its unstable structure. Under the elastic action of the first spring 203, the fixing plate 3 can automatically reset to ensure its stable use. The top of the first chute 201 is provided with a wire hole 205 that communicates with the top of the top cover 2, which can be used for wire connection. Before the buoy is used, the battery 5 is installed on the surface of the bottom plate 4 fixed inside the bottom of the upper housing 1, and the mounting frame 6 is fixed by the fixing bracket 601. The mounting frame 6 can be used to install detection elements such as water level, flow rate, flow direction, water temperature and water quality monitoring. After the wiring is completed inside, the hole cover 204 is fixedly connected to the top of the top cover 2, and the empty groove 206 corresponding to the wire hole 205 is opened on the outer side of the bottom of the hole cover 204 to ensure the wiring. When the top cover 2 and the upper housing 1 are threaded together, a sealing ring 104 is sandwiched in it to ensure sealing. The lower housing 7 at the bottom of the buoy is also connected to the upper housing 1 by a threaded connection. Before the connection, the outer side of the upper housing 1 is fitted with the first protective pad 10 by the upper outer extension edge 101, and the outer side of the lower housing 7 is fitted with the second protective pad 11 by the lower outer extension edge 701. The integrated extension of the upper outer extension edge 101 and the lower outer extension edge 701 can enhance the structural strength of the upper housing 1 and the lower housing 7, and facilitate the installation of the upper magnetic ring 102 and the lower magnetic ring 702 for launch and deployment. After the connection between the upper housing 1 and the lower housing 7, the contact surfaces between the first protective pad 10 and the second protective pad 11 can be sealed and fitted to ensure protective use. When the buoy is in use, it can be protected by the first protective pad 10 and the second protective pad 11 when it encounters the impact of wind and waves or the collision of debris and rocks. When the water flow impacts, the water flow will impact the outside of the buffer plate 703 fixed to the bottom end face of the lower shell 7. Through the equal angle arc setting of the buffer plate 703, the impact force can be rotated and deflected when the water flow impacts, so as to reduce the impact force on the buoy and ensure the safe use of the buoy for a long time. Example 2

[0033] The difference from Embodiment 1 is that this embodiment provides a solution based on Embodiment 1, using a different counterweight mechanism, which includes: The second fixed cylinder 81 is fixed to the bottom middle of the lower housing 7, so that the second fixed cylinder 81 replaces the fixed position of the first fixed cylinder 8. When the buoy enters the water, water enters the interior of the second fixed cylinder 81 through the through hole 801 in the middle of the second fixed cylinder 81. After the liquid level sensor 8101 fixed to the bottom surface of the interior of the second fixed cylinder 81 detects the presence of water, the controller 8102 determines that water has entered the buoy and controls the telescopic rod 8103 to extend, so that the counterweight block 9 connected to the bottom end of the telescopic rod 8103 extends downward to lower the center of gravity and ensure the stable use of the buoy. Example 3

[0034] The difference from Embodiment 1 is that this embodiment provides a solution based on Embodiment 1, using a different protective pad, namely a third protective pad 12. The third protective pad 12 is completely surrounded and disposed on the outside of the upper shell 1 and the lower shell 7, with its upper and lower ends respectively attached to the inner sides of the upper outer extension 101 and the lower outer extension 701. At the same time, a spiral groove 1201 is formed on the outer surface of the third protective pad 12. When the water flow impacts and causes the buoy to rotate, the spiral structure of the groove 1201 causes the buoy to rise and fall in the water, which can reduce the large displacement of the buoy caused by the water flow impact, and facilitate stable hydrological detection in a certain area.
