Technical Field

[0001] This invention relates to the field of dike technology, and in particular to a monitoring device and remote monitoring method for flooding of river dike sections. Background Technology

[0002] my country has basically constructed a flood control engineering system mainly consisting of dikes, reservoirs, and flood storage and detention areas in major river basins, forming a flood management concept that combines engineering measures with non-engineering measures. In the process of water conservancy development, in order to prevent problems caused by the rapid rise of water levels at dike sections, facilities and equipment are used for monitoring.

[0003] A Chinese patent application with application number 202010548853.4 discloses a monitoring device and remote monitoring method for flooding of river embankment sections. The device includes a hanging rod fixedly installed above the monitoring body, a horizontal plate fixedly installed above the hanging rod, and two grooves fixedly installed on the inner wall of the monitoring body. A guide rod 1 is installed inside the monitoring body, and a guide rod 2 is fixedly installed on one side of the guide rod 1. The guide rod 1 is fixedly connected to the groove through a wireless sensor contact switch, and the guide rod 2 is fixedly connected to the groove through an alarm contact switch.

[0004] In the prior art, when using a remote detection device to detect water level, the device cannot be adjusted in height. When different water level limits are required for alarm detection, the device needs to be re-fixed, which is too cumbersome. Therefore, this invention provides a monitoring device and remote monitoring method for flooding of river embankment sections. Summary of the Invention

[0005] The main objective of this invention is to provide a monitoring device and remote monitoring method for flooding of river embankment sections, aiming to solve the aforementioned technical problems.

[0006] To achieve the above objectives, this invention proposes a monitoring device for flooding of a river embankment section, comprising a semi-circular cover, a fixed column, and a movable column; a fixed plate is fixedly connected to the top of the fixed column; a first groove is formed at the top of the movable column; the fixed column is slidably connected within the first groove; both the fixed column and the first groove are square in plan view; a set of locking grooves are formed on the outer wall of the fixed column; a threaded column is threadedly connected to the outer wall of the movable column; and a water level detection element is provided inside the semi-circular cover.

[0007] In existing technologies, when using remote detection devices to detect water level height, the height of the detection device cannot be adjusted. Therefore, when different water level heights need to be limited for alarm detection, the detection device needs to be re-fixed, which is cumbersome. To address this, the present invention achieves the following effect in the aforementioned components: the fixing column and fixing plate are fixed to the river embankment by fasteners. When different water level heights need to be detected for alarm purposes, the threaded column can be rotated in the reverse direction to disengage from the locking groove. Then, the moving column can be manually pushed down. After adjusting the water level height to be measured, the threaded column is rotated in the forward direction to engage with the locking groove, thus fixing the moving column to the fixing column. The height of the water level detection device can be adjusted, facilitating alarm detection at different water level heights. The operation is simple and convenient, and it is applicable to river embankments of different heights, thus expanding its application range.

[0008] The water level detection device includes a fixed block; a fixed block is fixedly connected to the center of the top of the semi-circular cover; a second groove is formed at the bottom of the fixed block; a pushing block is fixedly connected to the bottom of the second groove by a spring; a first through groove is formed at the bottom of the pushing block; a rotating shaft is rotatably connected to the inner wall of the first through groove; a first rotating rod is fixedly connected to the rotating shaft, and torsion springs are provided at both ends of the rotating shaft; a first float is fixedly connected to one end of the first rotating rod, and a second float is fixedly connected to the other end; the inner diameter of the second float is larger than that of the first float; a position sensor is provided inside the second float; a pair of symmetrically distributed water outlet holes are formed on the semi-circular cover; a filter screen is fixedly connected to the inner wall of the bottom of the semi-circular cover.

[0009] The aforementioned components achieve the following effects: After the water enters the semi-circular cover, the water surface comes into contact with the second float. Utilizing the buoyancy of the water, the second float is pushed upwards. Then, the first rotating rod rotates, causing the second float to move upwards and the first float to move downwards. Simultaneously, the upward movement of the second float triggers the position sensor to determine the height of the water level rise. The time of the rise is used to determine the rate of water level rise. When the first and second floats are at the same horizontal level, the first rotating rod operates when the buoyancy of the second float equals the buoyancy of the first float plus the torsion spring force. At this point, the height of the second float is at its maximum, which is the predetermined water level alarm height. The filter screen prevents aquatic plants and other impurities from entering the semi-circular cover and affecting the water level detection device. Furthermore, when the water level fluctuates rapidly due to waves and wind, the collision and vibration between the second float and the filter screen enhances the cleaning of impurities on the filter screen.

[0010] A pair of symmetrically distributed alarms are fixed to the bottom of the fixed plate; a second wireless contact switch is fixed to the bottom of the second groove; and a first wireless contact switch is fixed to the top of the push block.

[0011] The effect achieved by the above components is as follows: after the first rotating rod is in the horizontal position, the push block will be in the highest position of compressing the spring. Then, the push block moves upward and drives the second wireless contact switch and the first contact switch to make contact with each other, thereby triggering the alarm. This makes it convenient to sound the alarm in rainy weather or in environments with poor visibility, and to remind people outside.

[0012] A first cavity is provided inside the movable column; a second through groove is provided on both side walls of the first cavity; a rotating shaft is rotatably connected in the second through groove; a second rotating rod is fixedly connected to the rotating shaft; the second rotating rod is fixedly connected to the outer side wall of the movable column by a spring; one end of the second rotating rod is located in the first cavity, and the other end is fixedly connected to a vibrating ball; the second rotating rod is driven to rotate by a pusher in the first cavity.

[0013] The effect achieved by the above components is as follows: When the monitoring device is performing monitoring, in order to prevent fish in the water from damaging the detection device, after the semi-circular cover is placed at the designated monitoring height, the second rotating rod will be driven to rotate by the pusher. The rotation of the second rotating rod will cause the vibrating ball to swing back and forth, thereby colliding with the outer wall of the semi-circular cover. The collision will generate vibration, and the vibration will make the semi-circular cover a vibration source, which can deter the surrounding organisms in the water. This can effectively ensure that the semi-circular cover is not affected by external objects and can effectively protect the water level detection device.

[0014] The pushing component includes a first rotating shaft; the first rotating shaft is rotatably connected to the inner wall of the first cavity, and both ends of the first rotating shaft extend out of the moving column and are fixedly connected to a fan wheel; a pair of third grooves are provided on the outer side wall of the first rotating shaft; a moving block is fixedly connected to the third groove by a spring; one side wall of the moving block is an arc-shaped surface;

[0015] The effect achieved by the above components is as follows: the rotation of the impeller drives the first rotating shaft to rotate, which in turn drives the moving block to rotate. When the moving block rotates from bottom to top, the arc-shaped surface of the moving block and the end of the second rotating rod come into contact with each other. At this time, the moving block pushes the second rotating rod to drive the vibrating ball closer to the semi-circular cover for collision. During the collision, the end of the second rotating shaft is in a fixed state. At this time, the moving block will enter the third groove under the action of the arc-shaped surface. At the same time, when the moving block rotates from top to bottom, the arc-shaped surface of the moving block will push the vibrating ball of the second rotating shaft to move away from the semi-circular cover. Then, when the first rotating shaft rotates, the moving block and the second rotating rod separate. At this time, the second rotating shaft will rebound under the action of spring force, thus enabling collision processing of the semi-circular cover and ensuring its working effect. At the same time, the cyclical rotation of the second rotating shaft can provide a continuous collision state in windy environments.

[0016] A push rod is fixedly connected to the top of the push block, and the push rod passes through the fixed block, the semi-circular cover and the moving column, extends into the first cavity and is fixedly connected to the push plate; the push plate is slidably connected to the inner wall of the first cavity; a first locking post is fixedly connected to the top of the push plate; a fourth groove is provided on the first locking post; a second locking post is fixedly connected to the bottom of the fourth groove by a spring; a positioning groove is provided on the arc-shaped surface of the moving block;

[0017] The aforementioned components achieve the following effects: When the alarm is activated, the alarm is in operation. To prevent vibration, when the push block causes the second and first wireless contact switches to contact each other, the push block moves upward, which in turn moves the push plate via the push rod. The push plate then moves the first locking post upward, causing the second locking post and the curved surface of the moving block to contact each other. Under the action of the spring in the second locking post and the moving block, the second locking post engages in the positioning groove, thereby limiting and fixing the first rotating shaft. This effectively prevents vibration from affecting the alarm's operation. When the alarm ends and the water level drops, the moving block moves downward, causing the second locking post to disengage from the locking groove, releasing the fixation on the first rotating shaft and ensuring subsequent operation.

[0018] A set of symmetrically distributed circular shells is fixed to the bottom of the semi-circular cover; a shell core is set inside the circular shells; the shell core is spherical;

[0019] The effect achieved by the above components is as follows: a set of circular shells is provided at the bottom of the semi-circular cover. When the vibrating ball and the semi-circular cover collide with each other, the core of the shell and the circular shell will undulate under the action of vibration, thereby increasing the vibration effect. At the same time, the circular shells are used to place the monitoring device on the ground. At this time, the circular shells can isolate the semi-circular cover from the ground and prevent impurities on the ground from affecting the water level detection component.

[0020] The shell core is fixed to the inner wall of the circular shell by a first elastic rope; a second cavity is opened in the moving column, and the second cavity is located directly below the first cavity; a push block is fixed to the bottom of the second cavity by an elastic sheet; the push block is connected to the shell core by a first thin rope; a set of magnetic layers is opened on the outer wall of the first rotating shaft; the push block is magnetic, and the magnetic layers and the push block attract each other.

[0021] The effect achieved by the above components is as follows: when the first rotating shaft rotates, the magnetic attraction between the magnetic layer and the pusher block is mutual. When the magnetic layer rotates and becomes misaligned, the pusher block will move back and forth under the action of the elastic sheet, and then pull the shell core back and forth through the first thin rope, which can generate vibration noise in the water, and further play the role of driving away aquatic organisms.

[0022] The top section of the fixing plate is arc-shaped; a solar panel is fixedly attached to the fixing plate, and the solar panel is also arc-shaped.

[0023] The effects achieved by the above components are as follows: the top of the fixing plate is arc-shaped to ensure that there will be no accumulation on rainy days, and the arc-shaped solar panel can be exposed to sunlight in different directions to ensure energy storage effect.

[0024] A remote monitoring method for a monitoring device used for flooding of river embankment sections, the remote monitoring method being suitable for the aforementioned monitoring device for flooding of river embankment sections, the method comprising the following steps:

[0025] S1: Fix the fixing plate to the river embankment with the fastener, and then adjust the height of the semi-circular cover above the water surface by using the threaded column and the locking groove through the moving column;

[0026] S2: When the water level rises, it will push the second float to rotate. The height value of the rise is obtained through the position sensor. When the water level rises to the alarm interface, the first float and the second float are on the horizontal surface. At this time, the first wireless contact switch and the second wireless contact switch are in contact with each other, thereby triggering the alarm to issue a warning.

[0027] S3: When the alarm is triggered, the push block moves upward, which will cause the second locking pin to engage in the positioning groove of the moving block, thereby limiting and fixing the first rotating shaft.

[0028] S4: After the prevention is completed, the height of the moving column can be manually adjusted to trigger an alarm for water levels at different heights.

[0029] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0030] (1) This invention allows the threaded column to be disengaged from the locking groove by rotating it in the opposite direction. Then, the movable column is manually pushed down. When the water level height to be measured is adjusted, the threaded column is rotated in the forward direction to lock it into the locking groove, thereby fixing the movable column on the fixed column. The height of the water level detection component can be adjusted to facilitate alarm detection and processing for different water level heights. The operation is simple and convenient. It can also be applied to river embankments of different heights, thus improving its application range.

[0031] (2) This invention utilizes the rotation of the wind turbine to drive the first rotating shaft to rotate. When the first rotating shaft rotates, it will drive the moving block to rotate. When the moving block rotates from bottom to top, the arc-shaped surface of the moving block and the end of the second rotating rod come into contact with each other. At this time, the moving block pushes the second rotating rod to drive the vibrating ball to approach the semi-circular cover for collision. The collision will generate vibration, and the vibration will form a vibration source for the semi-circular cover, which can deter the surrounding organisms in the water. It can effectively ensure that the semi-circular cover is not affected by external objects and can effectively protect the water level detection device. Attached Figure Description

[0050] like Figures 1 to 6As shown, an embodiment of the present invention provides a monitoring device for flooding of a river embankment section, comprising a semi-circular cover 1, a fixed column 11, and a movable column 12; a fixed plate 16 is fixedly connected to the top of the fixed column 11; a first groove 13 is formed at the top of the movable column 12; the fixed column 11 is slidably connected within the first groove 13; both the fixed column 11 and the first groove 13 are square in plan view; a set of locking grooves 14 are formed on the outer wall of the fixed column 11; a threaded column 15 is threadedly connected to the outer wall of the movable column 12; a water level detection element is provided inside the semi-circular cover 1; in the prior art, when using a remote detection device to detect water level height, because the water level detection device cannot be adjusted in height, when it is necessary to limit different water level heights for alarm detection, it is necessary to re-fix the detection element. The traditional measuring device is too cumbersome to operate. Therefore, in this invention, the fixed column 11 and fixed plate 16 are fixed to the river embankment by fasteners. When different water level heights need to be detected for alarm purposes, the threaded column 15 can be rotated in the reverse direction to disengage from the locking groove 14. Then, the movable column 12 can be manually pushed down. After adjusting the water level height to be measured, the threaded column 15 is rotated in the forward direction to engage with the locking groove 14, thus fixing the movable column 12 to the fixed column 11. The height of the water level detection element can be adjusted, facilitating alarm detection at different water level heights. The operation is simple and convenient, and it is applicable to river embankments of different heights, thus expanding its application range.

[0051] The water level detection component includes a fixed block 2; a fixed block 2 is fixedly connected to the center of the top of the semi-circular cover 1; a second groove 27 is provided at the bottom of the fixed block 2; a push block 21 is fixedly connected to the bottom of the second groove 27 by a spring; a first through groove 22 is provided at the bottom of the push block 21; a rotating shaft is rotatably connected to the inner wall of the first through groove 22; a first rotating rod 23 is fixedly connected to the rotating shaft, and torsion springs are provided at both ends of the rotating shaft; a first float 24 is fixedly connected to one end of the first rotating rod 23, and a second float 25 is fixedly connected to the other end; the inner diameter of the second float 25 is larger than that of the first float 24; a position sensor is provided inside the second float 25; a pair of symmetrically distributed water outlet holes 26 are provided on the semi-circular cover 1; a filter screen 28 is fixedly connected to the inner wall of the bottom end of the semi-circular cover 1; during operation, after the water enters the semi-circular cover 1, the water surface will come into contact with the second float 25, and the buoyancy of the water will be used to move the second float 25. When the ball 25 is pushed upward, the first rotating rod 23 rotates. At this time, the second float 25 moves upward and the first float 24 moves downward. Simultaneously, the second float 25 moves upward to the position sensor to determine the height of the water level rise. The time of the rise is used to determine the rate of water level rise. After the first float 24 and the second float 25 are at the same level, the first rotating rod 23 is in a situation where the buoyancy of the second float 25 is equal to the buoyancy of the first float 24 and the torsion spring force. At this time, the height of the second float 25 is at its maximum value, which is the limited water level alarm height. At the same time, the filter screen 28 can prevent some aquatic plants and other impurities from entering the semi-circular cover 1 and affecting the use of the water level detection device. At the same time, when the water level fluctuates rapidly due to waves and wind, the second float 25 will collide and vibrate with the filter screen 28, which can increase the cleaning of impurities on the filter screen 28.

[0052] A pair of symmetrically distributed alarms 32 are fixedly connected to the bottom of the fixed plate 16; a second wireless contact switch 31 is fixedly connected to the bottom of the second groove 27; a first wireless contact switch 3 is fixedly connected to the top of the push block 21; during operation, after the first rotating rod 23 is in the horizontal position, the push block 21 will be in the highest position of compressing the spring. Then, the push block 21 moves upward and drives the second wireless contact switch 31 and the first contact switch to make contact with each other, and then drives the alarm 32 to sound an alarm. This makes it convenient to sound an alarm in rainy weather or in environments with poor visibility, and to remind people outside.

[0053] A first cavity 33 is provided inside the movable column 12; a second through groove 34 is provided on both side walls of the first cavity 33; a rotating shaft is rotatably connected inside the second through groove 34; a second rotating rod 35 is fixedly connected to the rotating shaft; the second rotating rod 35 is fixedly connected to the outer wall of the movable column 12 by a spring; one end of the second rotating rod 35 is located inside the first cavity 33, and the other end is fixedly connected to a vibrating ball 36; the second rotating rod 35 is driven to rotate by a pusher inside the first cavity 33; during operation, when the monitoring device is monitoring, in order to prevent some fish in the water from damaging the detection device, after the semi-circular cover 1 is placed at the designated monitoring height, the second rotating rod 35 will be driven to rotate by the pusher. The rotation of the second rotating rod 35 will cause the vibrating ball 36 to swing back and forth, thereby colliding with the outer wall of the semi-circular cover 1. The collision will generate vibration, and the vibration will make the semi-circular cover 1 a vibration source, which can deter the surrounding organisms in the water, effectively ensuring that the semi-circular cover 1 is not affected by external objects, and effectively protecting the water level detection device.

[0054] The pushing component includes a first rotating shaft 4; the first rotating shaft 4 is rotatably connected to the inner wall of the first cavity 33, and both ends of the first rotating shaft 4 extend out of the moving column 12 and are fixedly connected to a fan wheel 41; a pair of third grooves 42 are provided on the outer side wall of the first rotating shaft 4; a moving block 43 is fixedly connected to the third groove 42 by a spring; one side wall of the moving block 43 is an arc-shaped surface 44; during operation, the rotation of the fan wheel 41 drives the first rotating shaft 4 to rotate, and the rotation of the first rotating shaft 4 drives the moving block 43 to rotate. When the moving block 43 rotates from bottom to top, the arc-shaped surface 44 of the moving block 43 and the end of the second rotating rod 35 come into contact with each other. At this time, the moving block 43 pushes the second rotating rod 35 to drive the vibrating ball. 36 approaches the semi-circular cover 1 to collide. During the collision, the end of the second rotating shaft is in a fixed state. At this time, the moving block 43 will enter the third groove 42 under the action of the arc surface 44. At the same time, when the moving block 43 rotates from top to bottom, the arc surface 44 of the moving block 43 will push the vibrating ball 36 of the second rotating shaft to move away from the semi-circular cover 1. Then, when the first rotating shaft 4 rotates, the moving block 43 and the second rotating rod 35 disengage. At this time, the second rotating shaft will rebound under the action of spring force, thus being able to collide with the semi-circular cover 1 to ensure its working effect. At the same time, the cyclic rotation of the second rotating shaft can achieve a continuous collision state in windy environments.

[0055] A push rod 5 is fixedly connected to the top of the push block 21, and the push rod 5 passes through the fixed block 2, the semi-circular cover 1 and the moving column 12, extends into the first cavity 33 and is fixedly connected to the push plate 51; the push plate 51 is slidably connected to the inner wall of the first cavity 33; a first locking post 52 is fixedly connected to the top of the push plate 51; a fourth groove 54 is provided on the first locking post 52; a second locking post 55 is fixedly connected to the bottom of the fourth groove 54 by a spring; a positioning groove 53 is provided on the arc-shaped surface 44 of the moving block 43; when working, in the alarm state, the alarm 32 is in the working state. At this time, in order to avoid vibration, the push block 21 drives the second wireless contact switch 31 and the first wireless contact switch. When the two parts come into contact, the upward movement of the push block 21 will drive the push plate 51 to move through the push rod 5. The movement of the push plate 51 will drive the first locking post 52 to move upward, so that the second locking post 55 and the arc surface 44 of the moving block 43 come into contact with each other. Then, under the action of the spring of the second locking post 55 and the moving block 43, the second locking post 55 is locked into the positioning groove 53, thereby limiting and fixing the first rotating shaft 4. At this time, the vibration generated at this time can effectively avoid affecting the working state of the alarm 32. When the alarm ends and the water level drops, the downward movement of the moving block 43 will drive the second locking post 55 to disengage from the locking groove 14, releasing the fixation of the first rotating shaft 4 and ensuring the subsequent working state.

[0056] A set of symmetrically distributed circular shells 6 are fixed to the bottom of the semi-circular cover 1; a shell core 61 is provided inside the circular shell 6; the shell core 61 is spherical; during operation, a set of circular shells 6 are provided at the bottom of the semi-circular cover 1. When the vibrating ball 36 and the semi-circular cover 1 collide with each other, the shell core 61 and the circular shell 6 will undulate under the action of vibration, thereby increasing the vibration effect. At the same time, the circular shells 6 are used to place the monitoring device on the ground. At this time, the circular shells 6 can isolate the semi-circular cover 1 from the ground and prevent impurities on the ground from affecting the water level detection element.

[0057] The core 61 is fixed to the inner wall of the circular shell 6 by a first elastic rope 65; a second cavity 62 is provided inside the moving column 12, and the second cavity 62 is located directly below the first cavity 33; a push block 63 is fixed to the bottom of the second cavity 62 by an elastic sheet 64; the push block 63 is connected to the core 61 by a first thin rope 66; a set of magnetic layers 67 is provided on the outer wall of the first rotating shaft 4; the push block 63 is magnetic, and the magnetic layers 67 and the push block 63 attract each other; during operation, when the first rotating shaft 4 rotates, the magnetic layers 67 and the push block 63 attract each other. When the magnetic layers 67 rotate and become misaligned, the push block 63 will move back and forth under the action of the elastic sheet 64, thereby pulling the core 61 back and forth through the first thin rope 66 to generate vibration noise in the water, which further serves to drive away aquatic organisms.

[0058] The top section of the fixed plate 16 is arc-shaped; a solar panel 68 is fixedly attached to the fixed plate 16, and the solar panel 68 is arc-shaped; when working, the arc-shaped top of the fixed plate 16 can ensure that there will be no accumulation in rainy weather, and the arc-shaped solar panel 68 can be irradiated by the sun in different directions to ensure the energy storage effect.

[0059] Working Principle: In existing technologies, when using remote detection devices to detect water level, the height of the detection device cannot be adjusted. When different water level heights need to be limited for alarm detection, the detection device needs to be re-fixed, which is cumbersome. Therefore, in this invention, the fixed column 11 and fixed plate 16 are fixed to the river embankment by fasteners. When different water level heights need to be detected for alarm, the threaded column 15 can be rotated in the reverse direction to disengage from the locking groove 14. Then, the moving column 12 is manually pushed down. After adjusting the water level to be measured, the threaded column 15 is rotated forward to engage with the locking groove 14, thus fixing the moving column 12 to the fixed column 11. The height of the water level detection device can be adjusted, facilitating alarm detection at different water level heights. The operation is simple and convenient, and it is applicable to river embankments of different heights, increasing its range of use. After the water enters the semi-circular cover 1, the water surface will contact the second float 25, utilizing the buoyancy of the water... The force pushes the second float 25 upward, and then the first rotating rod 23 rotates. At this time, the second float 25 moves upward and the first float 24 moves downward. At the same time, the position sensor uses the rising height of the second float 25 to determine the height of the water level rise, and the rising height time is used to determine the rising rate of the water level. After the first float 24 and the second float 25 are at the same horizontal plane, the first rotating rod 23 is in a situation where the buoyancy of the second float 25 is equal to the buoyancy of the first float 24 and the torsion spring force. At this time, the height of the second float 25 is at its maximum value, which is the limited water level alarm height. At the same time, the filter screen 28 can prevent some water plants and other impurities from entering the semi-circular cover 1 and affecting the use of the water level detection device. After the first rotating rod 23 is in the horizontal position, the push block 21 will be in the highest position of compressing the spring. Then, the push block 21 moves upward and drives the second wireless contact switch 31 to contact the first contact switch, and then drives the alarm 32 to sound an alarm. This can be conveniently alarmed in rainy weather or in environments with poor visibility, and can easily remind people outside.The rotation of the impeller 41 drives the first rotating shaft 4 to rotate. When the first rotating shaft 4 rotates, it drives the moving block 43 to rotate. When the moving block 43 rotates from bottom to top, the arc-shaped surface 44 of the moving block 43 and the end of the second rotating rod 35 come into contact with each other. At this time, the moving block 43 pushes the second rotating rod 35, causing the vibrating ball 36 to approach the semi-circular cover 1 for collision. During the collision, the end of the second rotating shaft is in a fixed state. At this time, the moving block 43, under the action of the arc-shaped surface 44, enters the third groove 42. Simultaneously, when the moving block 43 rotates from top to bottom... When the movable block 43's arc-shaped surface 44 pushes the vibrating ball 36 of the second rotating shaft away from the semi-circular cover 1, and then when the first rotating shaft 4 rotates, the movable block 43 and the second rotating rod 35 disengage. At this time, the second rotating shaft will rebound under the action of spring force, thus enabling collision processing of the semi-circular cover 1 to ensure its working effect. At the same time, the cyclic rotation of the second rotating shaft can provide a continuous collision state in windy environments. When in alarm mode, the alarm 32 is in working mode. In this case, to avoid vibration, the vibrating ball 36 of the second rotating shaft is pushed away from the semi-circular cover 1. When the moving block 21 causes the second wireless contact switch 31 and the first wireless contact switch 3 to come into contact, the upward movement of the moving block 21 will cause the moving plate 51 to move via the moving rod 5. The movement of the moving plate 51 will cause the first locking post 52 to move upward, so that the second locking post 55 and the arc-shaped surface 44 of the moving block 43 come into contact. Then, under the action of the spring of the second locking post 55 and the moving block 43, the second locking post 55 is locked into the positioning groove 53, thereby limiting and fixing the first rotating shaft 4. At this time, the vibration generated can be effectively prevented from affecting the operation of the alarm 32. In this state, when the alarm ends and the water level drops, the moving block 43 moves downward, causing the second locking post 55 to disengage from the locking slot 14, releasing the fixation on the first rotating shaft 4 and ensuring subsequent operation. When the first rotating shaft 4 rotates, the magnetic attraction between the magnetic layer 67 and the push block 63 causes the push block 63 to move back and forth under the action of the elastic sheet 64. This, in turn, pulls the shell core 61 back and forth through the first thin rope 66, generating vibration noise in the water and further driving away aquatic organisms.

[0060] like Figure 7 The following describes a remote monitoring method for a monitoring device used for monitoring flooding of river embankment sections. This remote monitoring method is suitable for the aforementioned monitoring device for monitoring flooding of river embankment sections. The steps of this method are as follows:

[0061] S1: Fix the fixing plate 16 to the river embankment with the fastener, and then adjust the height of the semi-circular cover 1 from the water surface by means of the threaded column 15 and the locking groove 14 and the moving column 12.

[0062] S2: When the water level rises, it will push the second float 25 to rotate. The height value of the rise is obtained through the position sensor. When the water level rises to the alarm interface, the first float 24 and the second float 25 are on the horizontal surface. At this time, the first wireless contact switch 3 and the second wireless contact switch 31 are in contact with each other, thereby driving the alarm 32 to issue a warning.

[0063] S3: When the alarm is triggered, the push block 21 moves upward, which will cause the second locking post 55 to engage in the positioning groove 53 of the moving block 21, thereby limiting and fixing the first rotating shaft 4.

[0064] S4: After the prevention is completed, the height of the movable column 12 can be manually adjusted to trigger an alarm for water levels at different heights.
