Description

Technical Field

[0001] This utility model relates to the technical field of water quality monitoring equipment, specifically a dual-energy-harvesting self-collecting water quality monitoring robot. Background Technology

[0002] Water quality monitoring equipment detects relevant indicators such as pH, residual chlorine, O3, and ORP in the pool water using probes and sends the results to a water quality monitoring and control instrument. This instrument then automatically alarms, displays, adjusts, and controls related equipment to maintain water quality. However, marine water quality monitoring robots have limited energy supplies, and their battery life directly affects their operational duration. Currently, most AUVs have short operating times, especially when operating far from shore, where the limitations are particularly pronounced, and energy replenishment is difficult: in the marine environment, robots cannot replenish energy as easily as land robots, and once the battery is depleted, they may need to return to their mother ship or base for charging.

[0003] Currently, most robots are powered by solar energy, but this requires sufficient sunlight, is greatly affected by weather, and has a relatively low energy density. Robots need large solar panel areas to collect enough energy, which to some extent limits the size and flexibility of the inspection robots.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-3 The diagram shows a dual-energy-harvesting self-collecting water quality monitoring robot, comprising a dual-energy-harvesting unit, an energy storage device 6, a water quality monitoring module, and a self-moving robot module. The water quality monitoring module includes an upper control unit and a lower multi-parameter integrated sensor. The energy storage device 6 is connected to the control unit's power socket via a coaxial cable for timely power supply. Each sensor probe is fixed to the lower left of the vehicle body 3 to collect water quality parameter data in real time. The self-moving robot module includes a rotor, pulleys, and floats 4. The rotor is fixed to the upper side of the vehicle body 3, and two pulleys pass through the vehicle body 3 and are fixed to the bottom of the vehicle body 3. Two floats 4 are connected to both ends of each pulley, with two opposing floats 4 distributed at both ends of the pulleys, enabling the robot's autonomous movement and navigation.

[0031] The upper-level power management unit of the water quality monitoring module is powered by the power distribution circuit of the energy storage device 6, and is connected to a flexible flat cable via a connector. The probes of the lower-level multi-parameter integrated sensor contact the water body through a streamlined window on the lower side of the vehicle body 3 to collect water quality data. Water quality monitoring is based on a core microprocessor, with each sensor receiving water quality data from the energy storage module. The main control chip processes and stores the collected data, sending it to the server on the online platform. The server platform stores and analyzes the water quality data using algorithms to determine the water quality status and, based on set thresholds and early warning mechanisms, determines whether any water quality anomalies have occurred. If an anomaly is detected, appropriate measures are taken promptly, such as sending alarm information to relevant personnel.

[0032] The self-propelled robot module is powered by an energy storage module. It controls the rotor and float 4 by running integrated navigation algorithms in a microprocessor. Based on preset monitoring tasks and target areas, it plans its movement path using GIS data.

[0033] The power management module output terminal is connected to the rear power distribution circuit. It has multiple DC-DC conversion modules inside, which power the water quality monitoring module on the left and the self-moving robot propulsion motor.

[0034] Energy storage device 6 stores the electrical energy converted by the dual energy harvesters and supplies power to different systems through distribution circuits. Located in the middle of vehicle body 3, energy harvesters are connected to a rectifier module via shielded twisted-pair cables. The module employs a full-bridge rectifier structure to convert unstable AC power into DC power. The rectifier output is connected to a power management module via DC wires, where lithium batteries or supercapacitors are used for storage in the middle of the main vehicle body 3.

[0035] The dual energy harvester includes a booster box 5 and a propeller 2. The booster box 5 is suspended and fixed to the inner wall of the vehicle body 3 and horizontally connected to the propeller 2 via a shaft. It also vertically connects to the energy storage device 6 below via the shaft. The propeller 2 is located on the outside of the vehicle body 3 and receives external thrust, converting the kinetic energy of the water flow into electrical energy through electromagnetic induction and friction. The thrust generated by the propeller 2 is calculated as follows: neglecting the compressibility and viscosity of the water flow, assuming uniform velocity and density at the impeller cross-section, and ignoring pressure gradient changes, the tower shadow effect of the tower hub on the impeller, and temperature changes, the flow field in the impeller channel satisfies the continuity equation, momentum equation, and energy conservation equation. By analyzing the relationship between velocity, pressure, and kinetic energy, the power, thrust, and torque parameters of the propeller 2 are solved.

[0036] See appendix Figure 4 As shown, the booster box 5 contains a first spur gear 5.3, a second spur gear 5.4, a first bevel gear 5.1, a second bevel gear 5.2, and a drive shaft. A circular through hole is opened at the bottom of the booster box 5. The first spur gear 5.3 and the drive shaft are fixedly connected by an interference fit and pivotally connected to the inner wall of the booster box 5. The second bevel gear 5.2 is fixedly connected to the upper end of the drive shaft. The second bevel gear 5.2 meshes with the first bevel gear 5.1. The first bevel gear 5.1 is connected and fixed to the external propeller 2 via a rotating shaft. A central shaft extending through the circular through hole into the booster box 5 is connected to the top of the top cover 6.2. The second spur gear 5.4 and the central shaft connected to the top of the top cover 6.2 are fixedly connected by an interference fit. The first spur gear 5.3 and the second spur gear 5.4 mesh with each other.

[0037] In the additional gearbox, the second spur gear 5.4 connected to the top cover 6.2 has fewer teeth, while the first spur gear 5.3 connected to the drive shaft has more teeth, in order to achieve the function of increasing rotation.

[0038] See appendix Figure 5-8 As shown, the energy storage device 6 includes a conical roller 6.3, a stator coil 6.6, an upper cover 6.2, a fixing ring 6.5, and an annular magnet 6.7. The stator coil 6.6 is shaped like a frustum of a cone and is fixedly connected to the inner wall of the vehicle body 3. A circular through hole is opened in the center of the stator coil 6.6. The upper cover 6.2 extends downward from the middle to form a rotating column, and the lower end of the rotating column passes through the circular through hole in the center of the stator coil 6.6 and is pivotally connected to the inner wall of the vehicle body 3. An annular sleeve is fixedly fitted on the rotating column above the stator coil 6.6, and a fixing ring 6.5 is fixedly installed on its outer ring (that is, the fixing ring 6.5 is not fixed to the stator coil 6.6, but when the upper cover 6.2 rotates, the upper cover 6.2 will drive the fixing ring 6.5 to rotate).

[0039] The retaining ring 6.5 has eight circular holes around it. Eight tapered rollers 6.3 are fitted into each of these eight holes. Specifically, each tapered roller 6.3 has an internal hexagon head screw 6.4 that passes through the retaining ring 6.5 and secures the tapered roller 6.3 to it using conventional methods such as snap-fit, threaded connection, or direct welding. This ultimately forms the top cover 6.2 and the tapered rollers 6.3 as the rotating parts, while the stator coil 6.6 serves as the stationary part.

[0040] The stator coil 6.6 is fitted with a circumferential outer shell 6.1. The outer shell 6.1 also wraps around the circumferentially arranged tapered rollers 6.3 and is fixedly connected to the interior of the car body 3.

[0041] To ensure the in-phase output of the eight triboelectric units, the lower friction contact surfaces of the eight tapered rollers 6.3 during the rolling process are always located on the same electrode. Finger-shaped electrodes are deposited on the tapered surface of the stator coil 6.6. Furthermore, an FEP film can be coated onto the electrodes as a friction material.

[0042] The principle of this invention is as follows: First, wave energy drives the propeller 2 to obtain the power to rotate the shaft. The rotation of the propeller 2 drives the central shaft to rotate. The central shaft increases the rotation speed through the booster box 5. The booster box 5 drives the upper cover 6.2 to rotate. The upper cover 6.2 drives the conical roller 6.3 mounted on the fixed ring 6.5 to rotate. During the rotation of the conical roller 6.3, on the one hand, the ring magnet 6.7 and the stator coil 6.6 generate relative motion, and the magnetic flux in the coil changes periodically, generating an induced electromotive force. On the other hand, the forked electrode is first deposited on the conical surface of the base, and then an FEP film is covered on the electrode as a friction material. The conical roller 6.3, as an independent friction layer, generates relative friction with the FEP film during the rolling process, causing the charge to be transferred alternately between the inner and outer electrodes, thereby generating the current output of the friction module, realizing electromagnetic-friction coupling dual energy capture, and converting wave energy into electrical energy. The generated electrical energy is rectified by a three-phase uncontrolled rectifier bridge, stored in the power management module, and then processed by the power distribution circuit to provide a stable energy supply for subsequent water quality monitoring and other equipment operation.

[0043] The above embodiments are provided for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
