Description

Technical Field

[0001] The present invention relates to the technical field of water level monitoring, and particularly to a water level monitoring alarm device. Background Art

[0002] Water level monitoring plays an indispensable role in many fields such as water conservancy, environmental protection, urban water supply and drainage, etc. Precise and reliable water level monitoring can provide key data support for water resource management, flood control and disaster reduction, industrial production, etc. With the continuous development of technology, various water level monitoring alarm devices have emerged. Some patented technologies have solved specific problems to a certain extent, but there are still many areas to be improved.

[0003] When the existing water level monitoring devices monitor waters with large waves, the relatively high-frequency waves are likely to cause deviations between the water level detection data and the actual data, thus generating incorrect information, resulting in poor credibility of the alarm information when the water level warning threshold is exceeded, and affecting the water level monitoring effect. A water level monitoring device for intelligent water conservancy disclosed in Patent No. 202421088585.2 uses structures such as a floating board, rollers, and rotating rods to sense water level changes and transmit signals, and cooperates with a capacitance liquid level gauge to monitor the water level. However, during the long-term operation of this device, the water level monitoring alarm device is troubled by performance degradation caused by impurity attachment. In waters with turbid water, eutrophication, or a large amount of aquatic plants, impurities such as algae, sediment, and aquatic plants are easily attached to the surfaces of key components such as the floating board and sensors. The growth of algae will increase the surface roughness of the components, increase the water flow resistance, and affect the smooth movement of the floating board; the accumulation of sediment may change the center of gravity and buoyancy distribution of the floating board, causing deviations in the measurement results; the entanglement of aquatic plants may directly hinder the normal lifting and lowering of the floating board, and even lead to device failures.

[0004] Therefore, it is necessary to provide a water level monitoring alarm device to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a water level monitoring alarm device to solve the existing problems in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A water level monitoring alarm device, comprising

[0008] a float assembly, the float assembly includes a main float body and an auxiliary float body, and the main float body and the auxiliary float body are connected by a connecting arm.

[0009] A steady flow cover, and a float assembly is located inside the steady flow cover. A cleaning component is arranged inside the steady flow cover. The cleaning component realizes the cleaning of the float assembly through a water pump, and the water pump is arranged on the outer wall of the steady flow cover.

[0010] As a further scheme of the present invention, the steady flow cover includes a cylindrical barrel body.

Flow guiding grooves are formed on the outer side wall of the cylindrical barrel body, and the flow guiding grooves are spirally distributed on the outer surface of the cylindrical barrel body.

[0011] As a further scheme of the present invention, the cross support frame includes two limiting circular frames arranged vertically and crosswise. Outer spherical ring grooves are formed on each of the limiting circular frames, and the two outer spherical ring grooves communicate with each other. The connecting ball is slidably connected in the outer spherical ring groove.

[0012] As a further scheme of the present invention, the main float body includes a main floating ball. Turbulence fins are arranged on the outer surface of the main floating ball. The inside of the main floating ball is divided into several sealed cavities by partition sheets.

[0028] Embodiment 1

[0029] As Figure 1 and Figure 5 — Figure 9 As shown, a water level monitoring alarm includes a float assembly 5. The float assembly 5 includes a main float 503 and an auxiliary float 502, and the main float 503 and the auxiliary float 502 are connected by a connecting arm 501. The main float 503 and the auxiliary float 502 are made of a new type of high-strength, low-density and more weather-resistant aviation-grade carbon fiber composite material. This material not only has several times the strength of ordinary engineering plastics, but also can effectively resist ultraviolet rays, high and low temperatures, and chemical corrosion, greatly extending the service life of the float. A cross support frame 504 is connected to the main float 503. One end of the flexible rope 1 is connected with a connecting ball 6, and the connecting ball 6 is slidably connected in the cross support frame 504.

[0030] The main float 503 includes a main float ball 503a, the outer surface of which is provided with a spoiler fin 503b, the interior of the main float ball 503a is divided into several sealed chambers by a spacer 503c, the outer layer of the spoiler fin 503b is made of a thin and tough flexible rubber material, which can bend adaptively according to the direction of the water flow, further guiding the water flow to smoothly bypass the float; the inner layer is embedded with a lightweight and high-strength carbon fiber skeleton to ensure that the spoiler fin 503b does not deform under long-term water flow impact, and at the same time, The spoiler fins 503b are arranged in a staggered manner, and the angle between adjacent fins is 15°-20°. Compared with uniform distribution, the water flow can be more fully disturbed, and the impact force of the water flow on the float can be reduced. The spoiler fins 503b guide and disturb the water flow. In addition to reducing the impact force of the water flow on the float, they can also effectively dissipate the energy of the water flow. When the water flow hits the spoiler fins 503b, the staggered arrangement structure causes the water flow to generate turbulence, and the kinetic energy of the water flow is dispersed and consumed in the turbulent process. This not only reduces the direct impact of the water flow on the float assembly 5, but also protects the float surface from erosion by high-speed water flow. The surface of the float that is in the water flow environment for a long time is easily worn due to the scouring of the water flow. The presence of the spoiler fins 503b greatly reduces the risk of such wear and tear, and further extends the service life of the float assembly 5. The role of the spoiler fins 503b is not limited to protecting the float itself, but also affects the water flow environment around the float. After the water flows through the spoiler fins 503b, its flow rate and direction change, forming a relatively stable water flow area around the float. This stable area helps to reduce other debris from approaching the float assembly 5 and reduce the possibility of debris entangled with the float and the rope. For example, in some waters with more aquatic plants, the water flow after the action of the spoiler fins can wash the aquatic plants to an area away from the float assembly 5, ensuring that the float assembly 5 can work normally in a complex water environment and improving the adaptability of the water level monitoring alarm under different water conditions.

[0031] The sealed cavity ensures that the float assembly 5 can maintain good floating performance as a whole even if part of the cavity is damaged.

[0032] The cross support frame 504 includes two limit circular frames 504a arranged vertically and crosswise, each limit circular frame 504a is provided with an outer spherical annular groove 504b, and the two outer spherical annular grooves 504b are interconnected, and the connecting ball 6 is slidably connected in the outer spherical annular groove 504b, and the depth of the outer spherical annular groove 504b is greater than the radius of the connecting ball 6, and the cross-sectional radius of the outer spherical annular groove 504b is equal to the radius of the connecting ball 6, which not only ensures the sliding of the connecting ball 6, but also prevents it from escaping from the annular groove, ensuring that in complex environments such as water flow, wind and waves, the connection between the flexible rope 1 and the main float 503 is stable and can adapt to the changes in the posture of the float.

[0033] An inner spherical annular groove 504c is provided on each limiting circular frame 504a, and the two inner spherical annular grooves 504c are interconnected. A limiting ball 503d is provided on the main float 503a, and the limiting ball 503d is slidably connected to the inner spherical annular groove 504c. The depth of the outer inner spherical annular groove 504c is greater than the radius of the limiting ball 503d, and the cross-sectional radius of the inner spherical annular groove 504c is equal to the radius of the limiting ball 503d, which not only ensures the sliding of the limiting ball 503d, but also prevents it from leaving the annular groove.

[0034] Under the action of water flow and wind and waves, the float assembly 5 will produce complex movement postures, including horizontal displacement, vertical rise and fall, and inclination at different angles. The sliding of the connecting ball 6 in the outer spherical ring groove 504b of the cross support frame 504 can adapt well to these dynamic changes. When the float assembly 5 is horizontally displaced by the impact of lateral water flow, the connecting ball 6 can slide along the outer spherical ring groove 504b. At the same time, due to the vertical cross structure of the cross support frame 504, the excessive displacement of the float assembly 5 can be limited to a certain extent, ensuring that it moves within a reasonable range. When the float assembly 5 produces a large vertical displacement due to the rapid rise and fall of the water level, the connecting ball 6 can also slide in the outer spherical ring groove 504b, ensuring that the flexible rope 1 always maintains a stably connected with the float assembly 5, and continuously and accurately transmits the float position information.

[0035] The cooperation between the limiting ball 503d and the inner spherical annular groove 504c plays an important stabilizing role for the float assembly 5 in a complex environment. When the float assembly 5 is violently shaken by wind and waves, the sliding of the limiting ball 503d in the inner spherical annular groove 504c can limit the excessive rotation and displacement of the main float 503a. For example, when wind and waves blow from a certain direction, the main float 503a may have a large degree of tilt and rotation. When the limiting ball 503d slides in the annular groove, it will generate a reverse force on the main float 503a, inhibiting its excessive movement, so that the main float 503a maintains a relatively stable posture. This stabilizing effect not only helps to ensure that the float assembly 5 accurately senses the water level, but also reduces the abnormal tension on the flexible rope 1 due to excessive shaking of the float, thereby extending the service life of the rope.

[0036] During the entire working process, the double float structure of the main float 503 and the auxiliary float 502 works together through the connecting arm 501 to effectively balance the torque and reduce the shaking of the float under the action of water flow and wind and waves. The spoiler fin 503b reduces the impact of the water flow on the float by guiding and disrupting the water flow.

[0037] According to Archimedes' principle, the torque can be effectively balanced. Since the two floating bodies are subjected to buoyancy at different positions, the line of action of the resultant force does not coincide with the line of action of gravity, and the torque generated can offset each other, thereby reducing the shaking of the float under the action of water flow and wind and waves, allowing the float to float more stably on the water surface and accurately reflect water level changes.

[0038] Under the interference of water flow and wind and waves, the float of the traditional float water level gauge is prone to shaking, resulting in measurement errors. When the float assembly 5 is immersed in water, it will receive an upward buoyant force, the magnitude of which is equal to the gravity of the displaced liquid. The double-float structure of the main float 503 and the auxiliary float 502 works together through the connecting arm 501. Since the line of action of the resultant buoyant force on the two floats does not coincide with the line of action of gravity, the generated torques cancel each other out. For example, when the main float 503 has a tendency to tilt due to the impact of water flow on one side, the reverse torque generated by the buoyant force on the auxiliary float 502 can balance this tendency, reducing the shaking of the float under the action of water flow and wind and waves, enabling the float assembly 5 to float more stably on the water surface like the float in the stable state of the traditional gauge, accurately reflecting the water level change, and being more stable than the traditional single-float structure in complex environments.

[0039] Embodiment 2

[0040] Based on Embodiment 1, as Figure 1 — Figure 2 shown, the float assembly 5 is located inside the flow stabilizer 2. The flow stabilizer 2 is made of high-strength aluminum alloy and is anodized on the surface to enhance corrosion resistance. The flow stabilizer 2 continuously provides a stable working environment for the float assembly 5. The flow stabilizer 2 includes a cylindrical barrel 201. Connecting cover frames 203 are threadedly connected to both the upper and lower ends of the cylindrical barrel 201. When it is necessary to clean the filter grille 204 or perform maintenance on the inside of the flow stabilizer, the staff can easily unscrew the connecting cover frame 203 for quick maintenance operations. The tightness of the threaded connection also ensures that there is no looseness between the connecting cover frame 203 and the cylindrical barrel 201 under the impact of water flow, ensuring the overall sealing and structural stability of the flow stabilizer. A filter grille 204 is installed on the connecting cover frame 203. The mesh size of the filter grille 204 is selected according to the floating objects in the monitored water area. For example, in waters with more waterweeds, a grille with a smaller mesh size is used to effectively block floating objects from entering the inside of the flow stabilizer 2 and prevent them from entangling the float and the rope, affecting the normal operation of the device. Regularly cleaning the filter grille can ensure the smoothness of the device. A flow guiding groove 202 is formed on the outer side wall of the cylindrical barrel 201, and the flow guiding groove 202 is spirally distributed on the outer surface of the cylindrical barrel 201, which can guide the water flow to flow smoothly around the float assembly 5 along a specific path, further reducing the interference of the water flow on the float. A detachable counterweight is provided at the bottom of the flow stabilizer 2, and the stability of the flow stabilizer 2 can be adjusted according to the actual water flow situation.

[0041] When water flows through the flow stabilizer cover 2, first of all, the filter grille 204 intercepts floating objects in the water to prevent them from entering the interior of the flow stabilizer cover 2 and affecting the normal operation of the float assembly 5. The water flow flows along the spiral diversion groove 202 on the outer wall of the cylindrical barrel 201. The spiral diversion groove 202 changes the direction of the water flow, making it smoothly surround the float assembly 5. During this process, the impact force of the water flow on the float is dispersed and weakened, reducing the swaying of the float and providing a more stable environment for the float assembly 5 to accurately sense the water level change. At the same time, by adjusting the counterweight at the bottom of the flow stabilizer cover 2 according to the water flow situation, it can ensure that the flow stabilizer cover 2 remains stable under different water flow conditions and continuously plays the role of stabilizing the flow. When the water flow situation changes, the flow stabilizer cover 2 needs to quickly adapt and remain stable. For example, when the river enters the flood season and the water flow speed suddenly increases, the counterweight at the bottom of the flow stabilizer cover 2 can play a role in time to enhance its stability. At the same time, the spiral diversion groove 202 will guide the high-speed water flow to more smoothly surround the float assembly 5. Although the water flow impact force increases, through the action of the flow stabilizer cover 2, the interference received by the float can still be controlled within a small range. When the water flow direction changes, such as the water flow at a turning point, the structural design of the flow stabilizer cover 2 enables it to adapt to the change of the water flow direction. The spiral diversion groove 202 will readjust the surrounding path of the water flow according to the change of the water flow direction to ensure that the float assembly 5 is finally in a stable water flow environment and accurately senses the water level change, providing continuous and reliable monitoring guarantee for the water level monitoring alarm under complex and changeable water flow conditions.

[0042] Embodiment III

[0043] On the basis of Embodiment II, as Figure 3 — Figure 4 shown, a cleaning component 4 is provided inside the flow stabilizer cover 2. The cleaning component 4 realizes the cleaning of the float assembly 5 through a water pump 3, and the water pump 3 is arranged on the outer wall of the flow stabilizer cover 2; the cleaning component 4 includes a spiral communication pipe 402. A cavity is formed inside the side wall of the flow stabilizer cover 2, and the spiral communication pipe 402 is located in the cavity. The water outlet end of the water pump 3 is communicated with the spiral communication pipe 402 through a diversion pipe 401. A spray pipe 403 is vertically communicated with the spiral communication pipe 402, and the spray pipe 403 penetrates through the flow stabilizer cover 2 and extends into the interior of the flow stabilizer cover 2. The included angle between adjacent spray pipes 403 remains the same, so that the water flow can be evenly sprayed on the surface of the float assembly 5.

[0044] When the water quality of the monitored water area is poor and impurities such as algae, silt, and waterweed are easily attached to the surface of the float component 5, the cleaning component 4 can be started according to the actual situation. For example, a timed cleaning mode can be set to start the cleaning program every 6 hours or 24 hours according to the water quality. The surface resistance or weight change of the float component 5 can also be monitored by a sensor. When a certain threshold is reached, the cleaning component 4 is automatically triggered to work. After the water pump 3 is started, water is drawn from the outside and, after pressurization, is transported to the spiral connecting pipe 402 through the guide pipe 401. The spiral connecting tube 402 evenly distributes the water flow to each spray pipe 403. Due to the special structure of the spiral connecting tube 402, the water flow can maintain a relatively stable pressure and flow rate when flowing in the tube, ensuring that each spray pipe 403 can spray with appropriate water pressure and water volume. The spray pipe 403 sprays the water flow to the surface of the float assembly 5. The strong water flow can wash away the algae, mud and other impurities attached to the surface of the float. For the water grass and other debris wrapped around the float and the spoiler fins, they can also be washed away by the impact of the water flow. During the spraying process, the water flow can not only clean the surface of the float assembly 5, but also flush the inside of the stabilizer cover 2 to a certain extent to prevent impurities from accumulating in the stabilizer cover 2. After the water flow is cleaned, part of it is discharged from the stabilizer cover 2 through the filter grille 204, and the other part forms a cycle in the stabilizer cover 2, and continues to participate in the cleaning process until the cleaning procedure is completed. In this way, the cleaning component 4 effectively keeps the float component 5 clean, ensuring that it can work normally in a complex water quality environment without affecting the accuracy of water level monitoring, and further improving the overall performance and reliability of the water level monitoring alarm.
