Description

Technical Field

[0001] This application relates to the field of water level monitoring, and in particular to a water level monitoring device for water conservancy projects. Background Technology

[0002] In the field of water conservancy engineering, water level monitoring plays a crucial role in project scheduling, flood control and drought relief, and water resource management. With the continuous development of water conservancy, the demand for accurate water level data collection and real-time transmission is increasing. Accurate water level monitoring data can provide strong support for scientific decision-making in water conservancy projects, help to rationally allocate water resources, ensure the safe and stable operation of water conservancy facilities, and is of great significance to the development of the entire water conservancy industry and social stability.

[0003] Currently, water level monitoring devices in water conservancy projects typically connect a float and a potentiometer indirectly. The float is placed in the water body to be monitored, and the float causes the resistance value of the potentiometer to change as the water level rises and falls. The change in resistance value is then mapped to the change in water level value, thereby measuring the water level change.

[0004] However, the floats and potentiometers of existing water level monitoring devices are directly exposed to the air, making them susceptible to wind loads, snow loads, or other environmental disturbances, as well as affecting their own guiding accuracy. This can lead to the devices failing to accurately measure water level changes. Solving these technical problems is a matter that those skilled in the art need to consider. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a water level monitoring device for water conservancy projects.

[0006] In one embodiment, the water level monitoring device for a water conservancy project includes a support member and a monitoring component. The support member is installed on the ground adjacent to the water body to be monitored. The monitoring component includes a monitoring part and a protective part with an internal receiving space. The protective part is connected to the support member, and a through groove is formed at the bottom of the protective part, communicating with the receiving space. The monitoring part includes a floating part, a resistance regulating part, and a control part. The resistance regulating part is built into the receiving space and connected to the protective part. The floating part is buoyantly disposed within the receiving space and is configured to rise and fall with changes in water level, guided by the receiving space. The floating part is drivenly connected to the adjusting shaft of the resistance regulating part, used to change the resistance value of the resistance regulating part as the water level rises or falls. The control part is electrically connected to the resistance regulating part to sense changes in water level.

[0007] Understandably, the physical shielding of the protective component 22 and the internal housing space 221 form a monitoring environment that integrates protection and guidance. This benefits the monitoring component 21 and its integration within the housing space 221, preventing the monitoring component 21 from being directly exposed to the external environment and reducing interference from wind loads, snow loads, or other environmental factors. Simultaneously, the protective component 22 provides precise guidance for the float, enhancing the transmission stability between the float and the resistance regulating component 212. This device improves the reliability and stability of the measurement data, resulting in higher credibility of the monitoring results and enhancing the monitoring performance of water level monitoring devices in water conservancy projects.

[0008] In one embodiment, the protective member has several through holes on its side wall near the bottom, and the through holes are connected to the receiving space.

[0009] Understandably, the through-hole ensures that the water levels inside and outside the protective structure remain synchronized in real time, guaranteeing the accuracy of monitoring. At the same time, the through-hole can dampen and buffer the violent fluctuations in the external water caused by waves or turbulence, making the water level changes inside the containment space more gradual.

[0010] In one embodiment, the monitoring component further includes a connector, which includes a rack and a first gear. The first gear is sleeved on the adjustment shaft of the resistance adjustment component. The rack is connected to the float and moves up and down with the float as the water level changes. The rack meshes with the first gear to drive the first gear to rotate so that the resistance value of the resistance adjustment component changes.

[0011] Understandably, compared to rope traction or linkage transmission, the rack and pinion connection offers a rigid connection. When the float changes slightly with the water level, the rack can precisely drive the first gear to rotate through meshing, thereby adjusting the resistance regulator. The rack and pinion connection eliminates the slippage or slack that can occur with flexible connections, improving the response speed of the resistance regulator to changes in water level.

[0012] In one embodiment, the rack includes two sets of teeth, which are located on both sides of the rack.

[0013] In one embodiment, the connector further includes at least two second gears, which are built into the receiving space and movably connected to the inner wall of the protective member. The at least two second gears are respectively disposed on both sides of the rack and mesh with the toothed teeth.

[0014] Understandably, the second gears on both sides clamp the rack, effectively restricting its horizontal freedom and forcing it to move only in a straight line against gravity. This connection method reduces the likelihood of the rack tilting, wobbling, or disengaging from the first gear due to uneven force during lifting and lowering.

[0015] In one embodiment, a track is connected to the side of the support member near the monitoring component, and the track is vertically arranged along the direction of gravity.

[0016] In one embodiment, the water level monitoring device for water conservancy projects further includes a driving component, which is connected to a protective component and is driven to a support component via a track guide.

[0017] Understandably, the connection between the drive unit and the track allows the monitoring device to adjust its height along the direction of gravity. When there is a large difference in water level, the overall height of the monitoring component can be adjusted via the drive unit to ensure that the monitoring component is always within a reasonable monitoring range. Furthermore, when the water level monitoring device in a water conservancy project needs maintenance or is threatened by a major flood, the drive unit can lift the entire monitoring component to a higher position above the water surface, facilitating maintenance or protecting the equipment.

[0018] In one embodiment, the float is connected to a stabilizing block, which is located on the side of the float away from the resistance adjustment element.

[0019] Understandably, the stabilizing block increases the weight at the bottom of the float, lowering its center of gravity. A low center of gravity ensures the float remains vertical and floats on the water, preventing it from capsizing or tilting during floating. This also ensures the rack moves along the direction of gravity, guaranteeing smooth operation of the drivetrain.

[0020] In one embodiment, the monitoring component further includes a wireless transmitter that is communicatively connected to the control component.

[0021] Understandably, wireless communication technology enables remote real-time uploading of water level data, eliminating the need for manual on-site readings. This allows for precise real-time control of water level data, meeting the demands of modern water conservancy projects for automated and information-based scheduling.

[0022] In one embodiment, a limiting member is connected to the top of the rack.

[0023] Understandably, the presence of the limiting component prevents the rack from disengaging from the first gear during its movement along the direction of gravity, thus ensuring the stable operation of the monitoring component. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 To be continued Figure 2 This application will be described in further detail.

[0028] In one embodiment, the water level monitoring device for a water conservancy project includes a support member 1 and a monitoring component 2. The support member 1 is installed on the ground adjacent to the water body to be monitored. The monitoring component 2 includes a monitoring element 21 and a protective element 22 with an internal receiving space 221. The protective element 22 is connected to the support member 1, and a through groove 222 is provided at the bottom of the protective element 22, which communicates with the receiving space 221. The monitoring element 21 includes a float 211, a resistance adjusting element 212, and a control element 213. The resistance adjusting element 212 is built into the receiving space 221 and connected to the protective element 22. The float 211 is floatably disposed within the receiving space 221 and is configured to rise and fall with changes in water level under the guidance of the receiving space 221. The float 211 is drivenly connected to the adjusting shaft of the resistance adjusting element 212 to change the resistance value of the resistance adjusting element 212 when the water level rises or falls. The control element 213 is electrically connected to the resistance adjusting element 212 to sense changes in water level.

[0029] In this embodiment, refer to Figure 1 and Figure 2The support component 1 can be made of square stainless steel plate and is set on the ground adjacent to the water body to be tested. The monitoring component 2 is set above the water surface of the water body to be tested. The protective component 22 can be cylindrical in shape, and the through groove 222 at the bottom of the protective component 22 communicates with the receiving space 221. The resistance adjustment component 212 can be a multi-turn precision potentiometer with a resistance of 10 kΩ. Known and feasible components can be selected, which will not be elaborated. The resistance adjustment component 212 is built into the receiving space 221 near the top of the protective component 22, and the side wall of the resistance adjustment component 212 away from the adjustment shaft is connected to the inner wall of the protective component 22. The control component 213 is set in the receiving space 221 near the resistance adjustment component 212 and is electrically connected to the resistance adjustment component 212. The float 211 can be made of high-density polyethylene material. The float 211 can be spherical with a diameter between 180 and 220 mm. The float 211 is connected to the adjustment shaft of the resistance adjustment component 212. The float 211 rises and falls with the change of the water level of the water body to be detected, thereby driving the adjustment shaft of the resistance adjustment component 212 to rotate and adjust the resistance value of the resistance adjustment component 212.

[0030] The physical shielding of the protective component 22 and the internal housing space 221 form a monitoring environment that integrates protection and guidance. This is beneficial for the monitoring component 21 and its integration within the housing space 221, preventing the monitoring component 21 from being directly exposed to the external environment and reducing interference from wind loads, snow loads, or other environmental factors. Simultaneously, the protective component 22 provides precise guidance for the float, enhancing the transmission stability between the float and the resistance regulating component 212. This device improves the reliability and stability of the measurement data, resulting in higher credibility of the monitoring results and enhancing the monitoring performance of the water level monitoring device in water conservancy projects.

[0031] In one embodiment, a track 11 is connected to the side of the support member 1 near the monitoring component 2, and the track 11 is vertically arranged along the direction of gravity.

[0032] In one embodiment, the water level monitoring device for water conservancy projects further includes a drive component 3, which is connected to the protective component 22. The drive component 3 is guided and driven to the support component 1 via the track 11.

[0033] In this embodiment, the track 11 is arranged along the direction of gravity and detachably connected to the side of the support member 1 near the protective member 22. The height of the track 11 along the direction of gravity is equal to that of the support member 1. The drive member 3 can be a motor. The side wall of the drive member 3 away from the output end is detachably connected to the side wall of the protective member 22 near the support member 1. The output end of the drive member 3 is engaged with the track 11, and the drive member 3 can drive the protective member 22 to rise and fall along the track 11. The connection between the drive member 3 and the track 11 allows the monitoring device to adjust its height along the direction of gravity. When the water level difference is large, the overall height of the monitoring component 2 can be adjusted by the drive member 3 to keep the monitoring component 2 within a reasonable monitoring range. At the same time, when the water level monitoring device of the water conservancy project needs maintenance or is threatened by a major flood, the drive member 3 can lift the entire monitoring component 2 to a high place above the water surface for easy maintenance or to protect the equipment.

[0034] In one embodiment, the monitoring component 21 further includes a connector 214, which includes a rack 2141 and a first gear 2142. The first gear 2142 is sleeved on the adjusting shaft of the resistance adjusting component 212. The rack 2141 is connected to the float 211 and rises and falls with the float 211 as the water level changes. The rack 2141 is meshed with the first gear 2142 to drive the first gear 2142 to rotate so that the resistance value of the resistance adjusting component 212 changes.

[0035] In this embodiment, refer to Figure 1 The first gear 2142 is sleeved on the adjusting shaft of the resistance regulating component 212 and detachably connected to the adjusting shaft. The bottom of the rack 2141 is connected to the top of the float 211, and the top of the rack 2141 meshes with the first gear 2142. Compared with rope traction or linkage transmission, the gear and rack 2141 meshing connection has the characteristics of a rigid connection. When the float 211 changes slightly with the water level, the rack 2141 can precisely drive the first gear 2142 to rotate through meshing, thereby adjusting the resistance regulating component 212. The gear and rack 2141 meshing connection eliminates the slippage or looseness that may exist in flexible connections, improving the response speed of the resistance regulating component 212 to water level changes.

[0036] In one embodiment, a limiting member 21411 is connected to the top of the rack 2141.

[0037] In this embodiment, the limiting member 21411 can be a square stainless steel block. The limiting member 21411 can prevent the rack 2141 from disengaging from the first gear 2142 during the movement along the direction of gravity, thus ensuring the stable operation of the monitoring component 21. In one embodiment, the rack 2141 includes two sets of teeth, which are located on both sides of the rack 2141.

[0038] In one embodiment, the connector 214 further includes at least two second gears, which are built into the receiving space 221 and movably connected to the inner wall of the protective member 22. The at least two second gears are respectively disposed on both sides of the rack 2141 and mesh with the tooth pattern.

[0039] In this embodiment, the connector 214 includes two second gears, which are built into the receiving space 221. The two second gears are positioned below the resistance adjusting member 212 along the direction of gravity and are movably connected to the inner wall of the protective member 22. The rack 2141 includes two sets of teeth, which mesh with the two second gears respectively. The meshing connection between the second gears on both sides and the rack 2141 increases the connection stability between the second gears and the rack 2141. The second gears on both sides clamp the rack 2141, effectively restricting its horizontal freedom and forcing it to move only in a straight line against gravity. This connection method reduces the occurrence of tilting, swaying, or disengagement from the first gear 2142 due to uneven force during lifting and lowering. In other embodiments, the protective member 22 may also be provided with an inner sleeve, the inner diameter of which is slightly larger than the outer diameter of the rack 2141, for partially surrounding the rack 2141 to achieve radial limiting of the rack 2141.

[0040] In one embodiment, the protective member 22 has a plurality of through holes 223 on its side wall near the bottom, and the plurality of through holes 223 are connected to the receiving space 221.

[0041] In this embodiment, the through hole 223 is formed at the bottom of the side wall of the protective member 22, and the through hole 223 is connected to the receiving space 221. The through hole 223 ensures that the water levels inside and outside the protective member 22 remain synchronized in real time, ensuring the accuracy of monitoring. At the same time, the through hole 223 can dampen and buffer the violent fluctuations of the external water body caused by waves or turbulence, making the water level changes inside the receiving space 221 more gradual. The floating member 211 is configured to be basically located inside the protective member 22, to prevent the floating member 211 from swaying too much along the axial direction due to the water flow after it comes out of the receiving space 221, and to avoid serious jamming between the rack 2141 and the resistance regulating member 212.

[0042] In one embodiment, the float 211 is connected to a stabilizing block 2111, which is located on the side of the float 211 away from the resistance adjustment member 212.

[0043] In this embodiment, the stabilizing block 2111 can be made of lead or stainless steel. The stabilizing block 2111 increases the counterweight at the bottom of the float 211, lowering its center of gravity. This low center of gravity ensures that the float 211 always maintains a vertical posture and floats on the water surface, preventing it from tipping or tilting during floating. It also ensures that the rack 2141 always moves in the direction of gravity, guaranteeing the smooth operation of the transmission chain.

[0044] In one embodiment, the monitoring component 2 further includes a wireless transmitter 23, which is communicatively connected to the control component 213.

[0045] In this embodiment, refer to Figure 1 and Figure 2 The wireless transmission component 23 can employ a long-distance communication module operating at a frequency of 433 MHz. The wireless transmission component 23 is communicatively connected to the control component 213 and is mounted on the top of the support component 1. Through wireless communication technology, remote real-time uploading of water level data is achieved, eliminating the need for manual on-site readings. This enables real-time and accurate control of water level data, meeting the demands of modern water conservancy projects for automated and information-based scheduling. It is understood that both the wireless transmission component 23 and the control component 213 can utilize known and feasible structures; their specific models, structures, and signal interaction logic are not detailed here.

[0046] The implementation principle of the water level monitoring device for water conservancy projects in this embodiment is as follows: The water level monitoring device in this embodiment provides stable support through the support member 1, and the protective member 22 protects the monitoring component 21 from the influence of the external environment. The float 211 rises and falls with the water level, and the resistance value of the resistance regulating member 212 is changed through the connecting member 214. The control member 213 senses the change in resistance value to monitor the water level. The through hole 223, the two sets of teeth of the rack 2141, the second gear, and the stabilizing block 2111 on the protective member 22 all improve the accuracy and stability of the monitoring. The wireless transmission member 23 realizes the real-time remote transmission of water level data, which facilitates the monitoring and management of the water level by the staff. Compared with the existing water level monitoring methods, the connection between the float and the potentiometer in this application is set inside the protective member 22, which effectively avoids the interference of wind load, snow load or other environmental factors, and has the advantages of stable monitoring performance and high reliability of monitoring results.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
