Description

Technical Field

[0001] This utility model relates to the field of data acquisition technology, and in particular to a remote data acquisition terminal for water pump flow. Background Technology

[0002] Remote data acquisition terminals for water pump flow are key equipment in smart water management, agricultural irrigation, and industrial water circulation systems, used to monitor the operating status and water output efficiency of water pumps in real time. However, existing terminals of this type still have many limitations in practical applications, especially in complex open water areas, that urgently need to be addressed.

[0003] First, there are shortcomings in equipment deployment and operational stability. Currently, most data acquisition terminals and water pumps are rigidly connected and fixedly installed on shore or underwater foundations. This installation method is difficult to adapt to environments with drastic water level fluctuations (such as reservoirs and rivers), easily leading to the water pump inlet being exposed to air, causing the pump to run dry, damaging the equipment, interrupting data acquisition, and potentially causing production accidents. Furthermore, fixed installations lack self-adaptive leveling capabilities when facing complex hydrological conditions such as wind, waves, and undercurrents, making the entire system prone to tilting, severely affecting the normal operation of the water pump and the accuracy of data acquisition.

[0004] Secondly, there are long-term maintenance challenges. Traditional terminal equipment, when submerged or exposed to water for extended periods, is highly susceptible to the accumulation of algae, shellfish, and other aquatic organisms on its casing and sensor interfaces. This biofouling increases equipment weight, alters its hydrodynamic properties, and can even clog sensor and pump inlets, leading to buoyancy failure, data distortion, or equipment damage. Frequent manual cleaning and maintenance are not only costly but also difficult to implement in remote or vast waterways, significantly increasing the operational burden. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a remote data acquisition terminal for water pump flow, which aims to improve the problem that existing installation methods are difficult to adapt to environments with drastic water level fluctuations (such as reservoirs and rivers), and easily lead to the water pump inlet being exposed to the air.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a remote data acquisition terminal for water pump flow, comprising a terminal body, wherein a control module and a communication module are provided within the terminal body, the terminal body is connected to a water pump via a connector and is used to acquire the flow data of the water pump, a floating bladder is connected to the terminal body, the floating bladder provides buoyancy for the water pump and the terminal body, an attitude sensing module is integrated inside the floating bladder, the attitude sensing module is electrically connected to the control module and is used to acquire the attitude data of the floating bladder.

[0007] As a further description of the above technical solution: The floating capsule is circumferentially provided with multiple independently controllable bionic tentacle structures. Each bionic tentacle structure has a micro-chamber inside. The terminal body is also provided with an air pump control module. The air pump control module is connected to the micro-chamber through an air passage and is controlled by the control module.

[0008] As a further description of the above technical solution: The floating capsule is made of flexible composite material and its outer surface is coated with an anti-fouling coating. The surface of the biomimetic tentacle structure is provided with micro-textures.

[0009] As a further description of the above technical solution: The air pump control module is also connected to a guide passage, which is respectively arranged around the floating bladder.

[0010] As a further description of the above technical solution: The attitude sensing module is an inertial measurement unit, which includes a three-axis accelerometer and a three-axis gyroscope.

[0011] As a further description of the above technical solution: A one-way valve is installed inside the guide passage.

[0012] As a further description of the above technical solution: The communication module is one or a combination of a 4G CAT1 communication module, an NB-IoT communication module, or a 5G communication module.

[0013] This utility model has the following beneficial effects: In this invention, a floating capsule provides basic buoyancy, and combined with a biomimetic tentacle active balancing system based on attitude sensing feedback, the terminal can effectively resist interference from wind, waves, and undercurrents, maintaining the water pump inlet at the optimal working depth. This fundamentally avoids problems such as cavitation and air intake caused by water level fluctuations or machine tilting, ensuring the continuous, stable, and efficient operation of the water pump, thereby guaranteeing the continuity and reliability of flow data acquisition.

[0014] In this invention, the design of the distributed guide path and one-way valve ensures the high efficiency, precision, and independence of the pneumatic control circuit, enabling the buoyancy adjustment of each bionic tentacle to respond quickly and accurately to control commands, thus enhancing the reaction speed and control accuracy of the entire balance system. Simultaneously, the one-way valve effectively prevents system-wide failure due to localized damage.

[0015] In this invention, the terminal transcends the traditional scope of single flow data acquisition. By integrating attitude data, vibration spectrum, and multi-dimensional information such as the pump's flow and pressure, it achieves in-depth insight into the health status of the pump unit and early fault diagnosis. This transforms the terminal from a simple data logger into an intelligent monitoring system with predictive maintenance capabilities, providing unprecedented data support for users to manage equipment, optimize operation, and formulate maintenance strategies.

[0018] 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.

[0019] Reference Figure 1-3 The present invention provides an embodiment of a water pump flow remote data acquisition terminal, comprising a terminal body 1, a control module 11 and a communication module 12 disposed therein, the terminal body 1 being connected to a water pump 2 via a connector and used to acquire the flow data of the water pump 2, the terminal body 1 being connected to a floating bladder 3, the floating bladder 3 providing buoyancy for the water pump 2 and the terminal body 1, the floating bladder 3 having an integrated attitude sensing module 4, the attitude sensing module 4 being electrically connected to the control module 11 and used to acquire the attitude data of the floating bladder 3.

[0020] The floating capsule 3 is provided with multiple independently controllable bionic tentacle structures 5 around its circumference. The bionic tentacle structures 5 are provided with micro chambers 51 inside. The terminal body 1 is also provided with an air pump control module 13. The air pump control module 13 is connected to the micro chambers 51 through an air passage and is controlled by the control module 11.

[0021] The floating capsule 3 is made of flexible composite material and its outer surface is coated with an anti-fouling coating. The surface of the biomimetic tentacle structure 5 is provided with micro-textures 52.

[0022] Specifically, the floating bladder 3 serves as the buoyancy foundation of the entire system, ensuring that the inlet of the water pump 2 is always submerged at the optimal water intake depth. When the system tilts due to wind, waves, or undercurrents, the attitude sensing module 4 integrated within the floating bladder sends tilt data to the control module 11 in real time. The control module 11 then drives the air pump control module 13 to inflate the micro-chamber 51 of the bionic tentacle structure 5 on the lower tilt side, increasing its volume and buoyancy; simultaneously, it vents air from the bionic tentacle on the higher tilt side, reducing its buoyancy. Through this independent and differentiated buoyancy adjustment, a righting torque is generated, driving the entire platform back to its balanced posture, thereby ensuring the stable operation of the water pump 2 and preventing air from being drawn in or pumped out due to the inlet being exposed above the water surface. Meanwhile, the micro-textures 52 on the surface of the biomimetic tentacle structure 5 and the anti-fouling coating on the float body can effectively destroy the attachment conditions of aquatic organisms such as algae and shellfish, achieve self-cleaning by utilizing the natural flow of water, significantly reduce the accumulation of biological dirt, and maintain the buoyancy performance of the float and the stability of the system.

[0023] The air pump control module 13 is also connected to a guide passage 14, which is set around the floating bladder 3.

[0024] Attitude sensing module 4 is an inertial measurement unit, which includes a three-axis accelerometer and a three-axis gyroscope.

[0025] A one-way valve 15 is installed inside the guide passage 14.

[0026] The communication module 12 is one or a combination of a 4G CAT1 communication module, an NB-IoT communication module, or a 5G communication module.

[0027] Specifically, the guide passage 14 forms a distributed airflow network, ensuring that the gas generated by the air pump control module 13 can be quickly and evenly delivered to the target bionic tentacle structure 5. The internal one-way valve 15 strictly prevents backflow of gas or liquid, ensuring the independence and controllability of the air pressure in each tentacle chamber, thereby accurately executing balance commands. The triaxial acceleration and triaxial gyroscope data collected by the attitude sensing module 4 are not only used to calculate the attitude angle of the float in real time, but their deeper value lies in the fact that after this dynamic data is uploaded to the cloud via the communication module 12, it can be fused and analyzed with the flow and pressure data of the water pump 2. For example, a continuous peak vibration at a specific frequency may indicate an imbalance or blockage of the impeller of the water pump 2; abnormal fluctuations in attitude data may be associated with inlet blockage or external collisions. This multi-dimensional data fusion upgrades the terminal from a single flow acquisition system to a comprehensive water pump 2 health status monitoring system. The communication module 12 is selected according to different application scenarios: NB-IoT is suitable for low-power, wide-coverage outdoor scenarios; 4G CAT1 achieves a balance between data volume and real-time performance; and 5G is used for critical tasks with extremely high requirements for control command latency, realizing a precise match between communication methods and business needs.

[0028] Working Principle: The floating capsule 3 serves as the buoyancy foundation of the entire system, ensuring that the inlet of the water pump 2 is always submerged at the optimal water intake depth. When the system tilts due to wind, waves, or undercurrents, the attitude sensing module 4 (i.e., the inertial measurement unit, including a three-axis accelerometer and a three-axis gyroscope) integrated within the floating capsule 3 monitors the system in real time and sends the attitude data to the control module 11. The control module 11 then drives the air pump control module 13 to precisely inflate the micro-chamber 51 of the bionic tentacle structure 5 on the lower tilt side through a distributed air path network consisting of a guide passage 14 (with a one-way valve 15 installed inside to prevent backflow), causing it to expand in volume and increase buoyancy. Simultaneously, the upper tentacle vents air to reduce buoyancy. This independent and differentiated buoyancy adjustment generates a righting torque, driving the entire platform to restore balance, thereby ensuring the stable operation of the water pump 2 and preventing air cavitation or intake. Meanwhile, the micro-textures 52 on the surface of the biomimetic tentacles work synergistically with the anti-fouling coating on the body of the floating bladder 3 to effectively disrupt the attachment conditions of aquatic organisms, achieving self-cleaning through natural water flow and maintaining the long-term stability of the system. Furthermore, the dynamic data collected by the attitude sensing module 4, along with the flow rate and pressure data of the water pump 2, are uploaded to the cloud via the communication module 12 for fusion analysis. This allows the terminal to not only monitor operating parameters but also identify specific vibration spectra and attitude anomalies, enabling early warnings of impeller imbalance, blockages, and other faults. Thus, it upgrades from a single flow acquisition device to a comprehensive water pump 2 health status monitoring system.

[0029] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
