Description
Technical Field
[0001] This invention relates to the field of water level monitoring devices, and specifically to an automated water level monitoring device for water conservancy projects. Background Technology
[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their goals. Most existing water conservancy projects are equipped with water level monitoring instruments to enhance the safety of the water conservancy projects.
[0003] Existing automated water level detection devices generally consist of a column erected on the riverbank and an ultrasonic radar mounted on the column's crossbar. In use, the ultrasonic radar emits ultrasonic waves into the water surface and detects the reflected sound waves to determine data such as wave crests and troughs. Alternatively, a measuring rod is erected in the water, and the water level is determined by visually observing the scale on the measuring rod or by attaching a float to the measuring rod.
[0004] However, when using ultrasonic radar to detect the crests and troughs of rivers, if there are suspended debris in the water, some ultrasonic waves will pass through the water surface and be reflected back by the debris, leading to misjudgments of water level. When using a measuring rod erected in the water to detect the water level, the underwater conditions are unknown. If there are reefs in front of the measuring rod, the water flow hitting the reefs will cause the water surface above them to move differently than other parts, resulting in errors in the measuring rod's water level detection. The detection effect is poor. In some areas with rainy and dry seasons, the hydrological conditions during the high-water and low-water periods are quite different, making it difficult for the above-mentioned detection agencies to detect accurately. Summary of the Invention
[0005] Based on this, the purpose of this invention is to provide an automated water level monitoring device for water conservancy projects, to solve the problems of using ultrasonic radar to detect the peaks and troughs of rivers. If there are suspended debris in the water, some ultrasonic waves will pass through the water surface and be reflected back by the debris, leading to misjudgment of the water level. When using a measuring rod erected in the water to detect the water level, the underwater conditions are unknown. If there are rocks in front of the measuring rod, the water flow hitting the rocks will cause the water surface above them to move differently than other parts, resulting in errors in the measuring rod's water level detection and poor detection results. Furthermore, in some areas with rainy and dry seasons, the hydrological conditions during the high-water and low-water periods are quite different, making it difficult for the above-mentioned detection methods to detect accurately.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An automated water level monitoring device for water conservancy projects includes a base, an outer support on the top surface of the base, and an inner support that is slidably and vertically connected to the inner support. An inner float is located inside the inner support, and multiple rotating rods are rotatably connected to the top surface of the inner float. A flow velocity detection float is rotatably connected to the top of each rotating rod. A flow velocity detection mechanism that cooperates with the inner float is located inside the outer support. The flow velocity detection mechanism includes a regular polygonal column, an impeller, a bevel gear, a rotating sleeve, and a wind speed detection wheel. The regular polygonal column is rotatably connected to the inner float, and a rotating sleeve that cooperates with the regular polygonal column is located inside the outer support. An impeller is rotatably connected to the top surface of the base, and a bevel gear that meshes with the rotating sleeve is connected to one end of the impeller's shaft. A wind speed detection wheel is connected to the top of the regular polygonal column above the inner float.
[0008] By adopting the above technical solutions, the inner float plate can detect the normal water level height, the rotating rod combined with the flow velocity detection float plate can detect the wind speed and water flow velocity under different conditions, the impeller can detect the water flow velocity when the regular polygonal column is in conjunction with the rotating sleeve, and the wind speed detection wheel can detect the wind speed after the regular polygonal column is separated from the rotating sleeve.
[0009] The present invention is further configured such that the flow rate detection mechanism includes a limiting bracket and a multi-section connecting rod, the limiting bracket is fixedly installed inside the outer bracket, and the rotating sleeve is rotatably connected to the limiting bracket, and the bottom end of the regular polygonal column is connected to a multi-section connecting rod that is rotatably connected to the base.
[0010] By adopting the above technical solution, the position of the fixed rotating sleeve of the bracket is limited, and the lifting range of the inner floating plate and the inner bracket is limited by the multiple connecting rods.
[0011] The present invention is further configured such that the inner float plate is composed of a float plate ring and an inner rotating ring, the inner rotating ring is located inside the float plate ring and is rotatably connected to the float plate ring, the rotating rods are all rotatably connected to the inner rotating ring, and the regular polygonal column is rotatably connected to the inner rotating ring.
[0012] By adopting the above technical solution, the inner rotating ring can rotate independently to prevent the inner rotating ring from driving the inner support to rotate. The rotation between the regular polygonal column and the inner rotating ring can ensure that the rotation between the regular polygonal column and the inner rotating ring will not affect each other.
[0013] The present invention is further configured such that a battery is disposed inside the base, and a chip is integrated inside the base.
[0014] By adopting the above technical solution, the battery can power electronic components, and the chip can detect data from the outside world.
[0015] The present invention is further configured such that the flow velocity detection float is composed of a float plate and a flow-pushing bowl, and the float plates of all the flow velocity detection floats can be combined together to form a circular tube shape, and the flow-pushing bowls are all located on the outside of the float plate.
[0016] By adopting the above technical solution, the floating plates can be combined into a cylindrical shape to prevent the floating plates from affecting the flow velocity detection floating plates' detection of wind speed. The propulsion bowl is located on the outside of the floating plates to facilitate the wind or water to push the flow velocity detection floating plates.
[0017] The present invention is further configured such that an outer float plate connected to a float ring is connected to the outer side of the inner support, and an inclined surface is provided on the top surface of the outer support to cooperate with a connecting rod connected to the outer float plate and the float ring.
[0018] By adopting the above technical solution, the outer float plate can increase the buoyancy of the inner float plate and increase the adsorption force between the water and the float plate. The inclined surface of the top surface of the outer support facilitates the better descent of the connecting rod between the outer float plate and the float plate ring.
[0019] The present invention is further configured such that all the sections of the multi-section connecting rod are pipes or rods with angular cross-sections.
[0020] By adopting the above technical solution, all the multi-section rods are pipes or rods with angular cross-sections, which can drive the multi-section connecting rods to rotate synchronously when the regular polygonal column rotates.
[0021] The present invention is further configured such that the bottom surface of the base is rotatably connected to a plurality of fixed pins, and the inner side of the fixed pins is connected to a ratchet gear that cooperates with the base. The bottom surface of the base is rotatably connected to a pawl that cooperates with the ratchet gear, and a return spring is connected between the pawl and the base. The bottom end of the fixed pin is inclined outward.
[0022] By adopting the above technical solution, when the fixed pin opens through the inclined plane, the ratchet, pawl and return spring can cooperate to prevent the fixed pin from rotating.
[0023] The present invention is further configured such that an angle sensor is provided at the pivot between the rotating rod and the inner rotating ring, and a water level sensor that cooperates with the outer support is installed on the float ring.
[0024] By adopting the above technical solution, the angle sensor can determine the peak and trough of the wave by detecting the angle of the rotating rod and the water level height detected by the water level sensor.
[0025] The invention is further configured such that a solar power generation panel is provided on the top surface of the outer floating plate, and a rotary generator connected to multiple connecting rods is installed inside the base.
[0026] By adopting the above technical solutions, both solar panels and rotary generators can provide power to the storage battery.
[0027] Compared with existing technologies, the present invention has the following main advantages and effects:
[0028] This invention utilizes an inner and outer support system. During the dry season, the impeller is submerged in water, and a rotating sleeve drives a regular polygonal column to rotate, which in turn drives a tachometer to detect the water flow rate during the dry season. Simultaneously, a closed flow velocity detection float can detect the wind speed. During the wet season, the inner float rises, causing the rotating rod to open. The water flow can then push the flow velocity detection float to rotate and detect the flow velocity. At the same time, the water flow's push on the float changes the angle of the rotating rod, allowing the detection of wave crests and troughs. Furthermore, the float rotates during detection, enabling the detection of the entire circular space, thus expanding the detection range and greatly reducing the impact of factors such as reefs on the detection results.

[0039] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present patent.
[0040] The present invention will now be described in further detail with reference to the accompanying drawings, illustrating an automated water level monitoring device for water conservancy projects.
[0041] like Figure 1-9As shown, an automated water level monitoring device for water conservancy projects includes a base 1, an outer support 2 on the top surface of the base 1, and an inner support 3 slidably connected inside the outer support 2. During installation, if it is during the high-water season, a "cofferdam" is constructed at the installation location, the water inside the "cofferdam" is pumped out, and then the device is inserted into the riverbed cleared by the cofferdam. Finally, cement is poured in for reinforcement. If it is during the low-water season, the device can be directly inserted into the riverbed and reinforced with hydraulic cement. Before pouring, a barrier is inserted around the device to prevent the uncured cement from being washed away by the water flow. A float ring 401 is slidably connected inside the inner support 3, and an inner rotating ring 402 is rotatably connected inside the float ring 401. The inner rotating ring 402 and the float ring 401 are connected... A rotation speed detector is installed, and four evenly arranged rotating rods 5 are rotatably connected to the top surface of the inner rotating ring 402. A flow velocity detection float 6 is rotatably connected to the other end of each rotating rod 5. An angle sensor 20 is installed at the connection between the rotating rod 5 and the inner rotating ring 402. A water level sensor 21, which cooperates with the outer support 2, is installed on the inner float 4. A flow velocity detection mechanism, which cooperates with the inner float 4, is set inside the outer support 2. During the dry season or when the water level does not reach the predetermined height, the float ring 401 is positioned low due to the low water level. Therefore, the inner support 3 restricts the rotating rods 5 from opening, and the flow velocity detection float 6 is in a vertical state. Wind can drive the rotating rods 5 and the inner rotating ring 402 to rotate by blowing the flow velocity detection float 6. The device can detect the rotational speed of the inner rotating ring 402, which is the wind speed at that time. Simultaneously, the flow velocity detection mechanism can detect the water flow velocity. During the dry season, the water flow is relatively gentle, resulting in smoother wave peaks and troughs. The inner float 4 can directly detect the water level. During the high-water season, when the water level reaches the preset height, the inner float 4 is pushed to the highest point of the inner support 3. At this time, the rotating rod 5 extends out of the inner support 3, so that the inner support 3 no longer restricts the rotating rod 5. Due to the outer center of gravity of the flow velocity detection float 6, the rotating rod 5 opens, and the flow velocity detection float 6 floats on the water surface. The water flow can then impact the flow velocity detection float 6, causing the rotating rod 5 to rotate. At this time, the rotational speed of the inner rotating ring 402 is the water flow velocity. Due to the surface tension of the water, the flow velocity detection... The float 6 is always held aloft by the water. The waves of the water flow will cause the flow velocity detection float 6 to rise and fall. When the flow velocity detection float 6 rises and falls, it will cause the rotating rod 5 to rotate. The angle sensor 20 can determine the wave crests and troughs by detecting the rotation angle of the rotating rod 5 and the water level height detected by the inner float 4. Since the rotating rod 5 is rotating while detecting wave crests and troughs, it can detect wave crests and troughs at all positions of the circular part with the length of the rotating rod 5 as the radius. By integrating and comparing the data, the influence of underwater reefs and other objects on the detection results can be minimized. At this time, the flow velocity detection mechanism rises to detect the wind speed. When the water level continues to rise, the inner float 4 can drive the inner support 3 to rise to adapt to higher water levels.
[0042] The flow velocity detection float 6 consists of a float plate and a pusher bowl, with the pusher bowl located on the outside of the float plate. The float plate can be assembled into a cylindrical shape. When the rotating rod 5 is upright, the float plate is assembled into a cylindrical shape to prevent the float plate from causing turbulence to the wind, which would make the flow velocity detection float 6 less accurate in detecting wind speed. When the rotating rod 5 is open and the flow velocity detection float 6 floats on the water surface, the pusher bowl is located below the water surface. The water flow impacts the concave surface of the pusher bowl, causing the rotating rod 5 to drive the inner rotating ring 402 to rotate. The convex surface of the pusher bowl can guide the water flow, greatly reducing the resistance between the water flow and the pusher bowl.
[0043] The specific structure of the flow rate detection mechanism is as follows: Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, a regular polygonal column 7 is rotatably connected to the middle of the inner rotating ring 402, and a multi-section connecting rod 12 rotatably connected to the base 1 is connected to the bottom end of the regular polygonal column 7. A limiting bracket 11 is fixedly installed inside the outer bracket 2, and a rotating sleeve 10 that cooperates with the regular polygonal column 7 is rotatably connected inside the limiting bracket 11. An impeller 8 is rotatably connected to the top surface of the base 1, and a bevel gear 9 that meshes with the rotating sleeve 10 is connected to one end of the shaft of the impeller 8. A wind speed detection wheel 13 is connected to the top of the regular polygonal column 7 above the inner floating plate 4. A speed sensor that cooperates with the multi-section connecting rod 12 is installed inside the base 1. During the dry season or when the water level has not reached the predetermined height, the inner floating plate 4 is lower, the regular polygonal column 7 meshes with the rotating sleeve 10, and the water flow impacts the impeller 8, causing the impeller 8 to rotate. This, in turn, drives the rotating sleeve 10 to rotate through the bevel gear 9, thereby causing the regular polygonal column 7 and the multi-section connecting rod 12 to rotate. The sensor detects the water flow velocity. During the high-water season, after the water level reaches the preset height, the regular polygonal column 7 rises with the inner float plate 4 and is pulled out of the rotating sleeve 10 (the function of the multi-section connecting rod is to limit the rise and fall of the regular polygonal column and prevent it from tilting after detaching from the rotating sleeve, so the regular polygonal column and the multi-section connecting rod always remain connected). The wind speed detection wheel 13 extends out of the inner support 3, and the wind can blow the wind speed detection wheel 13 to rotate (at this time, the wind speed is detected by the wind speed detection wheel 13, and the flow velocity detection plate floats on the water surface. The flow velocity detection float plate 6 at its bottom drives the inner rotating ring 402 to rotate. The speed sensor detects the flow velocity by detecting the speed of the inner rotating ring 402). This drives the regular polygonal column 7 to rotate and detect the wind speed. Waves may hit the wind speed detection wheel 13. Therefore, when the speed of the wind speed detection wheel 13 suddenly decreases, the speed is not recorded. The multi-section connecting rod 12 can also limit the rise and fall of the inner support 3.
[0044] Among them, the multi-section connecting rod 12 is a pipe or rod with an angular cross section, so that the regular polygonal column 7 can drive all the multi-section connecting rods 12 to rotate synchronously. The diameter of the outer circle of the telescopic part of the multi-section connecting rod 12 is smaller than the radius of the inner circle of the regular polygonal column 7, so that the rotating sleeve 10 will not affect the rotation of the regular polygonal column 7 after the water level reaches the threshold. The bottom surface of the regular polygonal column 7 is provided with a guide slope that cooperates with the rotating sleeve 10, so that the regular polygonal column 7 can be inserted into the rotating sleeve 10 when it descends again after disengaging from the rotating sleeve 10.
[0045] Based on the above structure, in this embodiment, an outer float plate 15 connected to the inner float plate 4 is sleeved on the outside of the inner support 3, and an inclined surface is provided on the top surface of the outer support 2 to cooperate with the connecting rod connected to the outer float plate 15 and the float plate ring 401. An inclined ring 14 is provided on the top surface of the inner support 3. The buoyancy can be increased by the outer float plate 15, and when the water level drops, the tension of the water on the inner float plate 4 can be increased by the outer float plate 15, which can better pull the inner float plate 4 down. When the inner float plate 4 is down, it can cooperate with the guide of the inclined ring 14 to pull the rotating rod 5 to retract and close.
[0046] To power the electronic components inside the device, a storage battery 19 is installed inside the base 1, a solar power panel is installed on the top surface of the outer floating plate 15, and a rotary generator connected to the multi-section connecting rod 12 is installed inside the base 1. The storage battery 19 can be powered by the solar power panel and the rotary generator. A chip is integrated inside the base 1 to facilitate the transmission of detection data to the outside world, making it more convenient to use.
[0047] Furthermore, to facilitate the installation of the device, multiple fixed pins 16 are rotatably connected to the bottom surface of the base 1, and a ratchet 17 that mates with the base 1 is connected to the inner side of the fixed pins 16. A pawl 18 that mates with the ratchet 17 is rotatably connected to the bottom surface of the base 1, and a return spring is connected between the pawl 18 and the base 1. The bottom end of the fixed pins 16 is inclined outward. When the device is inserted into the riverbed, the inclined surface of the fixed pins 16 will cause the fixed pins 16 to open outward. The ratchet 17, pawl 18 and return spring can prevent the fixed pins 16 from rotating, so that the device is temporarily fixed. When pouring cement, there is no need to manually straighten the device, which is more convenient.
[0048] Example 2
[0049] The difference from Embodiment 1 is that the base 1 is connected to a wire. During use, the electronic components inside the device are powered through the wire, and the detected data is transmitted to the outside through the same wire, making the power supply and information transmission of the device more stable.
[0050] During installation, if it is during the high-water season, a "cofferdam" is built at the installation site. The water inside the cofferdam is then pumped out, and the device is inserted into the cleared riverbed. Finally, cement is poured in for reinforcement. If it is during the low-water season, the device can be directly inserted into the riverbed and reinforced with hydraulic cement. Before pouring, a barrier is inserted around the device to prevent the uncured cement from being washed away by the water flow. When inserting the device into the riverbed, the inclined surface of the fixing pin 16 causes it to open outwards. The ratchet 17, pawl 18, and return spring cooperate to prevent the fixing pin 16 from rotating, thus temporarily fixing the device. Simultaneously, the impeller 8 needs to face the water flow. During use, in the low-water season or when the water level has not reached the predetermined height... The inner float 4 is positioned low, and the regular polygonal column 7 meshes with the rotating sleeve 10. The water flow impacts the impeller 8, causing it to rotate. This, in turn, drives the rotating sleeve 10 to rotate via the bevel gear 9, which in turn drives the regular polygonal column 7 and the multi-section connecting rod 12 to rotate. The water flow velocity is detected by a speed sensor. During the high-water season, when the water level reaches a preset height, the inner float 4 is pushed to the highest point of the inner support 3. At this time, the rotating rod 5 extends out of the inner support 3, causing the inner support... Frame 3 no longer restricts the rotating rod 5. Because the outer center of gravity of the flow velocity detection float 6 causes the rotating rod 5 to open, the flow velocity detection float 6 floats on the water surface. The water flow can then impact the flow velocity detection float 6, causing the rotating rod 5 to rotate. At this time, the rotational speed of the inner rotating ring 402 is the water flow velocity. Due to water surface tension, the flow velocity detection float 6 is always adhered to the water surface. The waves of the water flow will cause the flow velocity detection float 6 to rise and fall. When the flow velocity detection float 6 rises and falls, it causes the rotating rod 5 to rotate. The angle sensor 20 can determine the wave crests and troughs by detecting the rotation angle of the rotating rod 5 in conjunction with the water level height detected by the inner float 4. Furthermore, the rotating rod 5 rotates simultaneously when detecting wave crests and troughs, thus enabling detection... By integrating and comparing the data of all positions of the wave crests and troughs in the circular section with the length of the rotating rod 5 as the radius, the influence of underwater reefs and other objects on the detection results is minimized. At the same time, the regular polygonal column 7 follows the rise of the inner float plate 4 and pulls out the rotating sleeve 10, and the wind speed detection wheel 13 extends out of the inner support 3. The wind can blow the wind speed detection wheel 13 to rotate, which in turn drives the regular polygonal column 7 to rotate and detect the wind speed. Since the waves may hit the wind speed detection wheel 13, the rotation speed is not recorded when the speed of the wind speed detection wheel 13 suddenly decreases. The multi-section connecting rod 12 can also limit the lifting and lowering range of the inner support 3. When the water level continues to rise, the inner float plate 4 can drive the inner support 3 to rise to adapt to higher water levels.
[0051] This invention creatively detects water levels based on the different hydrological characteristics of the wet and dry seasons, avoiding the problem of inaccurate results when using the same method for water level detection in the past.
