Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrological monitoring equipment technology, and in particular to an integrated solar-powered low-power water level measuring instrument. Background Technology
[0002] The solar-powered low-power water level meter is an intelligent device that integrates solar power supply with low-power sensing and data transmission technologies. It can stably collect water level data from water tanks, rivers, and other water bodies for a long time without the need for traditional power grids, and then store and transmit the data. It is widely used in agricultural irrigation, water conservancy and hydrological monitoring, domestic water supply, and industrial and ecological scenarios where there is a lack of power supply and manual monitoring is difficult. It has advantages such as reducing deployment and maintenance costs, improving management efficiency, and strong environmental adaptability. It solves the water level monitoring problem in remote, power-free scenarios and is a key device for water conservation, efficiency improvement, and cost reduction in related fields.
[0003] A typical solar-powered low-power water level meter consists of a solar power module, a water level sensing module, and a data processing and transmission module. The solar power module enables energy self-sufficiency by storing energy during the day and using a battery circuit board for power at night or on cloudy days. A low-power MCU wakes up the water level sensing module at preset intervals to collect data via ultrasonic, pressure, or float sensors. The MCU then processes, converts, and filters the data before transmitting it remotely via local display and storage or a low-power wireless communication module as needed. The entire process is based on on-demand startup and minimal energy consumption, achieving grid-connected, low-power, and stable water level monitoring.
[0004] Existing low-power solar-powered water level gauges cannot be connected to the housing via threads, which also hinders easy disassembly and maintenance. In terms of installation compatibility, the lack of a universal threaded connection design forces the use of non-standard methods such as adhesive bonding and binding for fixation. This not only results in low stability, making the device prone to displacement and affecting measurement accuracy, but also fails to accommodate most standardized mounting accessories, requiring custom-made fixing structures, increasing installation complexity and cost. This is particularly unfavorable for scenarios where precise sensor positioning is required. Furthermore, the difficulty in disassembling the device necessitates forceful disassembly in case of malfunction, prolonging maintenance time, damaging the housing and internal wiring, compromising original sealing performance, and increasing the risk of subsequent malfunctions and labor costs. Therefore, this paper proposes an integrated low-power solar-powered water level gauge to address these issues. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1 to 3 This utility model provides an embodiment of an integrated solar-powered low-power water level measuring instrument, including a measuring rod 1 and a support mechanism 4. The measuring rod 1 is the core carrier for water level measurement, while the support mechanism 4 provides the installation and support foundation for solar power supply-related components. The two work together to ensure the realization of the overall function of the equipment. A measuring scale 2 is fixedly connected to the outside of the measuring rod 1. The measuring scale 2 allows staff to intuitively read the water level height and quickly obtain basic water level information without relying on electronic data, improving the convenience of on-site inspection. A sensing mechanism 6 is slidably connected inside the measuring rod 1.
[0036] The top of the measuring rod 1 is fixedly connected to the detection mechanism 3. As the core component for water level data acquisition and processing, the detection mechanism 3 can convert water level changes into identifiable signals to support subsequent data applications. The detection mechanism 3 includes a housing 31, which provides protection for the internal components of the detection mechanism 3 to prevent external rainwater and dust from affecting the operation of the components. The bottom of the housing 31 is fixedly connected to the top of the measuring rod 1. This fixing method can ensure that the housing 31 and the measuring rod 1 are stably connected and prevent the detection mechanism 3 from shifting due to vibration, wind and other factors in the outdoor environment, thus ensuring the accuracy of water level detection.
[0037] The outer shell 31 is threadedly connected to a protective shell 34. The threaded connection design allows the protective shell 34 to be quickly disassembled and installed, facilitating subsequent maintenance of the internal components of the detection mechanism 3. At the same time, the protective shell 34 further enhances the sealing and protection effect inside the outer shell 31, reducing the risk of component damage. Inside the outer shell 31, a battery circuit board 32 is fixedly connected by screws. The screw connection method facilitates the installation and replacement of the battery circuit board 32. The battery circuit board 32 can process the signals transmitted by the main control chip 33 and convert them into intuitive water level data, providing a basis for data storage or transmission. Inside the outer shell 31, the main control chip 33 is fixedly connected by spot welding, facilitating the maintenance and debugging of the main control chip 33. The main control chip 33 can sense changes in water level and generate corresponding signals, and is a key sensing component for water level detection.
[0038] The top of the main control chip 33 is slidably connected to the inside of the protective shell 34. This connection method allows the protective shell 34 to limit and protect the top of the main control chip 33, preventing excessive displacement of the main control chip 33 during equipment operation and ensuring sensing accuracy. The bottom of the main control chip 33 is slidably connected to the top of the battery circuit board 32, ensuring that the signal generated by the main control chip 33 is stably transmitted to the battery circuit board 32, reducing interference during signal transmission and improving the accuracy of data processing. The bottom of the measuring rod 1 is threadedly connected to the mounting shell 35. The mounting shell 35 is slidably connected to the base 37, and the base 37 is slidably connected to the sealing ring 36. The support mechanism 4 is slidably connected to the mounting component 5. The sliding connection facilitates the adjustment of the position of the mounting component 5 inside the support mechanism 4. The mounting component 5 can stably fix the support mechanism 4 at the designated installation point, ensuring the installation firmness of the solar-related components.
[0039] The support mechanism 4 includes a solar panel 41, which absorbs sunlight and converts it into electrical energy to provide energy support for the overall operation of the equipment. It is the core component for realizing the equipment's independence from the power grid and energy self-sufficiency. An adjustment component 42 is fixedly connected to the bottom of the solar panel 41. The fixed connection ensures that the solar panel 41 and the adjustment component 42 are firmly connected. The adjustment component 42 can adjust the angle of the solar panel 41 so that the solar panel 41 can better receive sunlight and improve the solar energy conversion efficiency. The adjustment component 42 has multiple holes inside, which provide space for the installation component 5 to pass through and adjust its position. It can also be used to further fix the position of the adjustment component 42 with bolts 44 and other components, thereby enhancing the stability of the support mechanism 4.
[0040] The internal grooved connection of the adjustment component 42 is connected to the bolt 44. The grooved connection allows the bolt 44 to be stably fixed inside the adjustment component 42. The bolt 44 can tightly connect the adjustment component 42 and the mounting bracket 43 to prevent them from loosening during equipment operation. The external thread of the bolt 44 is connected to the mounting bracket 43. The threaded connection has good connection firmness. The mounting bracket 43 provides support for the adjustment component 42 and the solar panel 41. It is also a key component that works with the mounting component 5 to fix the support mechanism 4.
[0041] Reference Figures 3 to 5 The mounting component 5 includes a sliding block 51, which is the core connecting component of the mounting component 5. By sliding within the relevant components, the mounting component 5 can be connected to the support mechanism 4 and the embedded shell 54. A limiting plate 56 is fixedly connected to the outside of the sliding block 51. The fixed connection ensures that the limiting plate 56 moves synchronously with the sliding block 51. The limiting plate 56 can limit the sliding range of the sliding block 51 within the adjusting component 42, preventing the sliding block 51 from extending too far into the adjusting component 42 and affecting the installation stability. The bottom of the limiting plate 56 is slidably connected to the top of the adjusting component 42. The slidable connection facilitates the adjustment of the position of the limiting plate 56 with the sliding block 51, and at the same time allows the limiting plate 56 to fit tightly against the top of the adjusting component 42.
[0042] To enhance the stability of the connection between the mounting component 5 and the adjusting component 42, the outer side of the sliding block 51 is slidably connected to the inside of the adjusting component 42. This sliding fit facilitates the insertion of the sliding block 51 into the adjusting component 42, laying the foundation for the subsequent connection with the pre-embedded shell 54. At the same time, the position of the sliding block 51 inside the adjusting component 42 can be finely adjusted according to the installation requirements. The sliding plate 52 is slidably connected inside the sliding block 51. The sliding connection allows the sliding plate 52 to move flexibly inside the sliding block 51, providing a power transmission path for the extension and retraction of the limiting block 53. A spring 57 is fixedly connected to the inner side of the sliding plate 52. The fixed connection ensures that the spring 57 generates a stable elastic force on the sliding plate 52.
[0043] Spring 57 can move sliding plate 52 by its own extension and retraction, thereby realizing the extension and retraction of limiting block 53. It is the key power component for fixing and disassembling mounting component 5. Limiting block 53 is fixedly connected to the outside of sliding plate 52. The fixed connection allows sliding plate 52 to drive limiting block 53 to move synchronously. Limiting block 53 can be inserted into the slot 55 of embedded shell 54 to fix sliding block 51 and embedded shell 54, thereby stably fixing support mechanism 4 in a designated position. The outside of limiting block 53 is slidably connected to the inside of sliding block 51. The slidable connection facilitates the extension and retraction of limiting block 53 inside sliding block 51. During installation, limiting block 53 can be retracted so that sliding block 51 can pass into embedded shell 54. After installation, limiting block 53 is extended to achieve fixation.
[0044] The outer side of the sliding block 51 is slidably connected to the embedded shell 54. The slidable connection facilitates the insertion of the sliding block 51 into the embedded shell 54. The embedded shell 54 is fixed in the designated position in advance, providing a basic carrier for the fixing of the installation component 5 and the support mechanism 4. The outer side of the limiting block 53 is slidably connected to the inside of the embedded shell 54. The slidable connection facilitates the movement of the limiting block 53 inside the embedded shell 54 and its engagement with the slot 55, ensuring that the limiting block 53 can stably fix the sliding block 51 to the embedded shell 54. The top of the embedded shell 54 is slidably connected to the bottom of the adjusting component 42. The slidable connection facilitates the precise docking of the adjusting component 42 and the embedded shell 54, ensuring that the sliding block 51 can be smoothly inserted into the embedded shell 54. At the same time, it also allows the bottom of the adjusting component 42 to fit tightly with the top of the embedded shell 54, enhancing the stability of the support mechanism 4 after installation.
[0045] The interior of the embedded shell 54 is provided with a slot 55, which provides a locking space for the limiting block 53. When the limiting block 53 slides into the slot 55, the slot 55 can limit the limiting block 53, preventing the sliding block 51 from coming out of the interior of the embedded shell 54, thus ensuring the stability of the fixing effect of the installation component 5. The outer side of the limiting block 53 is slidably connected to the interior of the slot 55. The slidable connection facilitates the smooth sliding of the limiting block 53 into the slot 55, and after locking, the limiting block 53 and the slot 55 can fit tightly together, further improving the firmness of the connection between the sliding block 51 and the embedded shell 54, and ensuring that the support mechanism 4 is stably fixed in the designated position.
[0046] refer to Figure 2 and Figure 3 The sensing mechanism 6 includes a lower shell 61, the outer side of which is slidably connected to the inside of the measuring rod 1. This sliding connection allows the lower shell 61 to be flexibly adjusted in position within the measuring rod 1 according to actual water level changes or maintenance needs, making it easy to adapt to different monitoring scenarios. A pressure sensor 62 is slidably connected inside the lower shell 61. This sliding connection allows the pressure sensor 62 to be finely adjusted within the shell 61, ensuring that it can accurately contact the water entering the measuring rod 1, thereby accurately acquiring water pressure data. An upper shell 63 is threadedly connected to the outer side of the lower shell 61. This threaded connection not only achieves a stable connection between the upper shell 63 and the lower shell 61, but also facilitates quick disassembly for inspection or replacement of the internal pressure sensor 62, ensuring the continuous and stable operation of the sensing mechanism 6.
[0047] Working principle: When the staff needs to install the solar panel 41, the pre-embedded shell 54 can be fixed in the designated position in advance. Then, the mounting bracket 43 is placed on top of the pre-embedded shell 54, and the sliding plate 52 is pressed into the sliding block 51. The sliding plate 52 will then move the limiting block 53 into the sliding block 51. After the sliding block 51 passes through the inside of the adjusting component 42 and reaches the inside of the pre-embedded shell 54, the sliding plate 52 can be released. The sliding plate 52 will then be pushed outward by the compressed spring 57, causing the limiting block 53 to slide out of the inside of the sliding block 51 and into the inside of the slot 55. At this time, the mounting bracket 43 can be fixed in the designated position by the cooperation of the limiting plate 56 and the limiting block 53.
[0048] After the measuring rod 1 is installed in the appropriate position, multiple measuring scales 2 are provided on the outside of the measuring rod 1. The water level can then be visually observed by measuring the scales 2. The protective shell 34 and the outer shell 31 are connected by threads, allowing for quick disassembly of the protective shell 34. This allows for testing and maintenance of the main control chip 33 and battery circuit board 32 inside. The main control chip 33 can collect signals and upload them to the cloud. All working logic is processed through the main control chip 33. The bottom of the measuring rod 1 is provided with a mounting shell 35. The mounting shell 35 is tightened by threads to protect the bottom from being blocked by bottom mud, which would affect the detection. The water level detection is handled by the pressure sensor 62. Water will enter the interior of the measuring rod 1 through the holes opened inside the base 37, and the pressure sensor 62 can then detect it.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
