Description

Technical Field

[0001] This utility model belongs to the field of water level monitoring technology, and in particular relates to an adjustable-length wireless communication water level measuring device. Background Technology

[0002] Water level monitoring is a core foundational task in fields such as water conservancy projects, municipal water supply, environmental governance, and industrial production. The accuracy, real-time nature, and equipment adaptability of the data directly affect the scientific validity of critical decisions regarding flood control scheduling, water resource allocation, and production safety management. However, current mainstream water level gauge products still have many technical limitations in practical applications, making it difficult to meet the monitoring needs of complex scenarios. Specific pain points are as follows: Traditional float-type and submersible level gauges typically employ a fixed cable and bracket design, relying on wired methods such as RS485 and Ethernet for data transmission. Once the cable length is fixed at the factory, it cannot be flexibly adjusted. For example, if a level gauge used for shallow water monitoring needs to be moved to deep water, a longer cable, bracket, and even the core sensor must be replaced. Conversely, if a level gauge used for deep water monitoring needs to be moved to shallow water, the cable of the level sensor must be re-cut and rewired; otherwise, the sensor may touch or even be buried in silt, leading to inaccurate level measurements or even equipment damage. These frequent changes between deep and shallow water monitoring scenarios not only increase the procurement cost of level monitoring equipment but also require downtime for disassembly, recalibration, and debugging, causing monitoring interruptions and severely impacting data continuity.

[0003] Therefore, there is an urgent need to design an adjustable-length wireless communication water level measurement device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-length wireless communication water level measuring device, which has the advantages of flexible range adjustment and adaptability to different depth scenarios, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of the adjustable-length wireless communication water level measuring device of this utility model is as follows: An adjustable-length wireless communication water level measuring device includes a data receiving module and a data acquisition module. The data acquisition module is used to collect water level data. The data acquisition module is electrically connected to the data receiving module and transmits the collected water level data to the data receiving module. Both the data acquisition module and the data receiving module are connected to steel wire ropes. A winding and unwinding assembly is provided between the data acquisition module and the data receiving module. Both the data acquisition module and the data receiving module are connected to the winding and unwinding assembly via steel wire ropes. The winding and unwinding assembly can wind and unwind the steel wire ropes of the data acquisition module and / or the data receiving module.

[0006] Furthermore, the take-up and take-up assembly includes a bracket, within which are a first take-up reel and a second take-up reel. Both the first take-up reel and the second take-up reel can rotate relative to the bracket. The first take-up reel is connected to the data acquisition module via a steel wire rope, and the steel wire rope connected to the data acquisition module is wound around the first take-up reel. The second take-up reel is connected to the data receiving module via a steel wire rope, and the steel wire rope connected to the data receiving module is wound around the second take-up reel.

[0007] Furthermore, both the first and second take-up reels are equipped with manual locking devices. After the length of the wire rope is adjusted, the first and / or second take-up reels are fixed by the manual locking devices.

[0008] Furthermore, both the first and second take-up reels are equipped with constant force springs, which can balance the tension of the wire rope in real time. When the first and / or second take-up reels take up the wire rope, the constant force springs assist the first and / or second take-up reels in taking up the wire rope.

[0009] Furthermore, both the first and second take-up reels are equipped with first hooks on their wire ropes, and the data acquisition module and data receiving module are equipped with second hooks.

[0010] Furthermore, the data acquisition module is equipped with a water level sensor, which collects water level data.

[0011] Furthermore, the data acquisition module includes an acquisition MCU module, an RS485 communication module, and an acquisition LoRa wireless communication module. The communication terminal of the acquisition MCU module is connected to the RS485 communication module and the acquisition LoRa wireless communication module. The water level sensor transmits water level data to the acquisition MCU module through the RS485 communication module. The acquisition MCU module saves the data. The acquisition LoRa wireless communication module transmits water level data and acquisition time information to the data receiving module.

[0012] Furthermore, the data acquisition module also includes a LoRa acquisition antenna, which provides network services for the LoRa wireless communication module.

[0013] Furthermore, the data receiving module includes a receiving MCU module, an NB-IoT communication module, and a receiving LoRa wireless communication module.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0019] The following is a reference to the appendix. Figure 1 To be continued Figure 6 This invention describes an adjustable-length wireless communication water level measuring device.

[0020] An adjustable-length wireless communication water level measuring device includes a data receiving module 12 and a data acquisition module 11. The data acquisition module 11 is used to collect water level data. The data acquisition module 11 is electrically connected to the data receiving module 12. The data acquisition module 11 transmits the collected water level data to the data receiving module 12. Steel wire ropes are connected to both the data acquisition module 11 and the data receiving module 12. A winding and unwinding assembly 13 is provided between the data acquisition module 11 and the data receiving module 12. Both the data acquisition module 11 and the data receiving module 12 are connected to the winding and unwinding assembly 13 through steel wire ropes. The winding and unwinding assembly 13 can wind up and unwind the steel wire ropes of the data acquisition module 11 and / or the data receiving module 12.

[0021] By adjusting the length of the wire rope through the extension and retraction component 13, the device can adapt to different water depth environments and is suitable for various water level measurement scenarios, such as rivers, reservoirs, or wellheads, thus improving the versatility of the device. Furthermore, the electrical connection between the data acquisition module 11 and the data receiving module 12 ensures the real-time transmission of water level data, reduces data latency, and facilitates real-time monitoring and rapid response. At the same time, the wire rope connection method makes the module easy to deploy and retrieve, reducing operational complexity.

[0022] The take-up and take-down assembly 13 includes a bracket, and a first take-up reel and a second take-up reel are provided inside the bracket. Both the first take-up reel and the second take-up reel can rotate relative to the bracket. The first take-up reel is connected to the data acquisition module 11 via a steel wire rope, and the steel wire rope connected to the data acquisition module 11 is wound around the first take-up reel. The second take-up reel is connected to the data receiving module 12 via a steel wire rope, and the steel wire rope connected to the data receiving module 12 is wound around the second take-up reel.

[0023] The first and second take-up reels control the wire ropes of the data acquisition module 11 and the data receiving module 12, respectively, allowing the positions of the two modules to be adjusted independently. This facilitates the precise placement of measurement points, avoids mutual interference, and simplifies the length adjustment process. Users can quickly complete the deployment manually, saving time and manpower.

[0024] Both the first and second take-up reels are equipped with manual locking devices 132. After the length of the wire rope is adjusted, the first and / or second take-up reels are fixed by the manual locking devices 132. After adjustment, the manual locking devices 132 can firmly fix the take-up reels, prevent the wire rope from slipping or loosening accidentally, ensure that the measurement position remains fixed, and improve the accuracy of data acquisition.

[0025] Both the first and second take-up reels are equipped with constant force springs. These springs balance the wire rope tension in real time. When the first and / or second take-up reels are winding the wire rope, the constant force springs assist them in winding. The constant force springs provide auxiliary force during the winding and unwinding of the wire rope, reducing the force required for manual operation and making the winding and unwinding process easier and smoother. This is especially suitable for scenarios requiring long-term or frequent adjustments. Furthermore, the constant force springs balance the tension in real time, preventing the wire rope from being too tight or too loose, reducing the risk of wear and breakage, and improving the safety and durability of the device.

[0026] Both the first and second take-up reels have a first hook 131 connected to their wire ropes, and the data acquisition module 11 and the data receiving module 12 have a second hook 14 connected to them. The first hook 131 of the first take-up reel can be hooked to the second hook 14 of the data acquisition module 11, and the first hook 131 of the second take-up reel can be hooked to the second hook 14 of the data receiving module 12.

[0027] The wire rope is made of galvanized rust-proof material and coated with fluoroplastic to enhance wear resistance. Both ends are connected to the take-up reel and the first hook respectively through snap-on connectors, making disassembly and replacement convenient.

[0028] The data acquisition module 11 is equipped with a water level sensor 10, which collects water level data.

[0029] The data acquisition module 11 includes an acquisition MCU module 111, an RS485 communication module, and an acquisition LoRa wireless communication module 115. The communication terminal of the acquisition MCU module 111 is connected to the RS485 communication module 114 and the acquisition LoRa wireless communication module 115. The water level sensor 10 transmits water level data to the acquisition MCU module 111 through the RS485 communication module 114. The acquisition MCU module 111 saves the data. The acquisition LoRa wireless communication module 115 transmits water level data and acquisition time information to the data receiving module 12.

[0030] The data acquisition module 11 also includes a LoRa acquisition antenna 116, which provides network services for the LoRa wireless communication module 115.

[0031] The data acquisition module 11 also includes an acquisition power interface 113 and a power conversion module 112. The power conversion module 112 receives 12V power from the acquisition power interface 113 and converts it into 5V power. The acquisition power interface 113 is connected to the acquisition MCU module 111 through the power conversion module 112 to supply power to the acquisition MCU module 111. The acquisition power interface 113 is also connected to the water level sensor 10 through the power conversion module 112 to supply power to the water level sensor 10.

[0032] The data receiving module 12 includes a receiving MCU module 121, an NB-IoT communication module 123, and a receiving LoRa wireless communication module 126. The receiving MCU module 121 is connected to the NB-IoT communication module 123 and the receiving LoRa wireless communication module 126. After the receiving LoRa wireless communication module 115 receives the data from the data acquisition module 11, it is transmitted to the receiving MCU module 121. The receiving MCU module 121 saves the data. The data from the data acquisition module 11 is sent to the remote server through the NB-IoT communication module.

[0033] The data receiving module 12 also includes a Bluetooth communication module 124, which is connected to the communication terminal of the receiving MCU module 121 and can be configured with parameters via a mobile APP.

[0034] The data receiving module 12 also includes a receiving LoRa antenna 127 and an NB-IoT Bluetooth dual antenna 125. The receiving LoRa antenna 127 provides network services for the receiving LoRa wireless communication module 126, and the NB-IoT Bluetooth dual antenna 125 provides network services for the NB-IoT communication module 123 and the Bluetooth communication module 124.

[0035] The data receiving module 12 also includes a receiving power interface 122, which supplies power to the receiving MCU module 121.

[0036] The acquisition MCU module 111 and the receiving MCU module 121 also have sleep mode and clock reading functions, specifically: When the water level measuring device is not performing a measurement task, the acquisition MCU module 111 and the receiving MCU module 121 will enter sleep mode, and the acquisition LoRa wireless communication module 115 and the receiving LoRa wireless communication module 126 will also enter low-power mode. At the same time, the power supply to most of the peripheral circuits will be turned off, so that the water level measuring device enters sleep state. At this time, the current of the entire device is reduced to the nanoamp level, thereby greatly reducing the power consumption of the device. When the water level measuring device needs to perform water level monitoring, the receiving MCU module 121 will wake up and send the acquisition command to the acquisition LoRa wireless communication module 115. After receiving the acquisition command, the acquisition MCU module 111 will wake up and turn on the power supply of the peripheral circuits to collect water level data.

[0037] The device is equipped with a high-precision clock built into the acquisition MCU module 111 and the receiving MCU module 121 to provide accurate time. Each time the device is woken up, it can be automatically calibrated to the server time. The system is woken up according to the device's sleep time and data acquisition time set in the acquisition MCU module 111 and the receiving MCU module 121, thereby ensuring the stability of the device during use.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
