Description

Technical Field

[0001] This utility model relates to the field of power monitoring technology, and more specifically, to a real-time monitoring device for new energy power. Background Technology

[0002] With the profound transformation of the global energy structure, the new energy industry is showing a vigorous development trend, especially in the power sector, where the installed capacity of new energy power generation is constantly increasing, and new energy power equipment such as electric vehicles are becoming increasingly popular. However, new energy power systems have their own unique complexity and dynamism, and traditional power monitoring methods are no longer sufficient to meet the requirements of new energy power systems for real-time performance, accuracy, and reliability.

[0003] New energy sources of electricity are diverse, including solar, wind, and hydropower. However, the power generation process of these energy sources is greatly affected by natural conditions, exhibiting significant intermittency and volatility. Taking photovoltaic power generation as an example, changes in sunlight intensity lead to large fluctuations in output power; wind power generation is constrained by wind speed and direction, resulting in highly unstable power output. This unstable power output poses a significant challenge to the stable operation of the power system. Failure to monitor power parameters in a timely and accurate manner may lead to problems such as grid voltage fluctuations and frequency deviations, and even threaten the safety of the entire power system.

[0004] Meanwhile, the widespread application of new energy power equipment has placed higher demands on the security and stability of power supply. For example, if key parameters such as charging current and voltage cannot be monitored in real time during the charging process of electric vehicles, overcharging and overvoltage faults may occur, which will not only shorten battery life but also pose serious safety hazards and may cause accidents such as fires. Moreover, as the scale of new energy power systems continues to expand, power networks are becoming increasingly complex. Traditional monitoring equipment and methods are lagging behind in data acquisition, transmission, and processing, making it difficult to achieve comprehensive and real-time control over the operating status of the power system. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a real-time monitoring device for new energy power, which can achieve precise positioning and stable connection of the charging connector through the ingenious design of magnetic drive components and control sleeve.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A real-time monitoring device for new energy power includes a charging gun body, a built-in charging module installed inside the charging gun body, a control sleeve fixedly connected to the end of the charging gun body, a matching charging connector slidably installed inside the control sleeve, an installation groove opened at the upper end of the charging connector, a magnetic drive component fixedly installed in the installation groove, an electromagnet corresponding to the magnetic drive component fixedly installed inside the charging gun body, and the charging connector and the built-in charging module connected by a flexible cable.

[0010] Furthermore, the magnetic drive component includes a mounting base fixedly installed in the mounting groove. The upper end of the mounting base has a lifting groove, and a matching telescopic block is slidably installed in the lifting groove. A compression spring is fixedly installed between the telescopic block and the bottom wall of the lifting groove. A magnetic block is fixedly installed on the end of the mounting base near the electromagnet. Stops are fixedly installed on both the left and right sides of the upper end of the mounting base. Under the action of the magnetic field of the electromagnet, the magnetic block can indirectly drive the charging connector to move back and forth inside the charging gun body through the mounting base. When the mounting base moves, the control sleeve applies a squeezing force to the telescopic block, causing it to overcome the elastic force of the compression spring and enter the lifting groove. At this time, the mounting base can move normally until it is blocked by the stop and stops and achieves positioning, which can ensure the stability of the charging connector after movement.

[0011] Furthermore, the upper end of the telescopic block has a trapezoidal structure that is smaller at the top and larger at the bottom, and both the left and right ends are rounded.

[0012] Furthermore, the control sleeve includes a fixing ring that is fixedly connected to the charging gun body. The upper left and right sides of the fixing ring are fixedly installed with inner buckling blocks. The inner buckling blocks can not only apply pressure to the telescopic block, but also fit into the telescopic block and the stop block to achieve positioning.

[0013] Furthermore, a pair of integrally formed strip-shaped sliders are fixedly installed on the outer end of the charging connector. A pair of strip-shaped grooves matching the strip-shaped sliders are opened on the inner side of the fixing ring, and the strip-shaped sliders are slidably installed on the inner side of the strip-shaped grooves. The cooperation between the strip-shaped sliders and the strip-shaped grooves can improve the stability of the charging connector when it moves and prevent non-working rotation.

[0014] Furthermore, anti-collision protrusions are fixedly installed at both the upper and lower ends of the charging gun body, and the anti-collision protrusions are raised structures facing outwards, which can provide collision protection when the charging gun body is accidentally dropped, reducing the damage caused by direct impact.

[0015] Furthermore, the charging gun body has heat dissipation holes at both the front and rear ends, and a dustproof mesh is fixedly installed inside the heat dissipation holes. The heat dissipation holes can dissipate heat in time during charging, and the dustproof mesh can isolate foreign objects from the outside.

[0016] Furthermore, the built-in charging module includes a charging circuit, a microcontroller, a current detection unit, and a voltage detection unit.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] (1) This utility model achieves precise positioning and stable connection of the charging connector through the ingenious design of the magnetic drive component and control sleeve. The cooperation between the magnetic block and the electromagnet ensures that the charging connector will not loosen due to slight shaking of external force during the charging process, thus ensuring the continuity of the charging process. At the same time, the current detection unit and voltage detection unit of the built-in charging module can monitor the charging current and voltage in real time and accurately. Once an abnormality occurs, the microcontroller quickly controls the charging circuit to stop charging and physically disconnects it, effectively avoiding safety hazards such as overcharging and overvoltage, greatly improving the safety of the charging process, and protecting the service life of the charging equipment and battery.

[0020] (2) The charging gun body of this utility model is made of high-strength engineering plastic material. Combined with the anti-collision protrusions at the top and bottom, it can effectively resist external impacts such as accidental drops and collisions, reducing the risk of equipment damage due to physical damage. The design of heat dissipation holes and dustproof nets not only ensures that the equipment can dissipate heat in time during the charging process, preventing the performance of internal components from deteriorating or being damaged due to overheating, but also isolates external dust, debris and other foreign objects from entering the equipment, avoiding short circuits and other faults caused by the accumulation of foreign objects.

[0030] Example 1:

[0031] Please see Figures 1-4 A real-time monitoring device for new energy power includes a charging gun body 1. The charging gun body 1 is made of high-strength engineering plastic, possessing good mechanical strength, impact resistance, and weather resistance, capable of withstanding external forces such as collisions and friction during daily use. It also possesses a certain degree of flame retardancy, ensuring safe use. The charging gun body 1 houses a built-in charging module 101, which consists of a charging circuit, a current detection unit, and a voltage detection unit. The charging circuit employs a high-efficiency switching power supply circuit design, using MOSFET power devices and a high-frequency transformer to achieve high conversion efficiency, stably converting the input electrical energy into voltage and current suitable for the charging equipment. The current detection unit uses a Hall current sensor, utilizing the Hall effect principle to quickly and accurately detect the charging current magnitude with an accuracy of ±1%. The voltage detection unit uses a high-precision resistor voltage divider network combined with a high-precision analog-to-digital converter (ADC) to achieve accurate measurement of the charging voltage, with a measurement error not exceeding ±0.5%.

[0032] The control sleeve 2, which is fixedly connected to the end of the charging gun body 1, consists of a fixing ring 201 and an inner snap-fit ​​block 202. The fixing ring 201 is made of aluminum alloy, and the inner snap-fit ​​block 202 is made of reinforced polyoxymethylene (POM) plastic. A charging connector 3 is slidably installed on the inner side of the control sleeve 2. A pair of integrally molded strip sliders 7 are fixedly installed on the outer end of the charging connector 3, which cooperate with the strip grooves 203 on the inner side of the fixing ring 201. Both the strip sliders 7 and the strip grooves 203 are made of stainless steel and are precision machined with low surface roughness, which ensures the smoothness and stability of the movement of the charging connector 3 and effectively prevents it from rotating in a non-working direction during movement.

[0033] The magnetic drive component 9, located in the mounting slot at the upper end of the charging connector 3, includes a mounting base 901, a magnetic block 902, a telescopic block 903, a compression spring 904, and a stop 905. The mounting base 901 is made of engineering plastic, possessing good insulation properties and a certain degree of mechanical strength. The magnetic block 902 uses neodymium iron boron permanent magnet material, characterized by high remanence, high coercivity, and high energy product, enabling it to generate strong magnetic force under the magnetic field of the electromagnet 8. The telescopic block 903 is made of high-strength nylon, with a trapezoidal structure at the top (smaller at the top, larger at the bottom) and rounded corners on both sides, facilitating its engagement with the inner locking block 202 of the control sleeve 2 to achieve the telescopic function. The compression spring 904 is made of high-quality stainless steel spring wire, possessing good elasticity and fatigue resistance, maintaining stable elasticity after multiple extensions and retractions. The stop 905, also made of engineering plastic, limits the movement range of the mounting base 901, ensuring the stability of the charging connector 3 after movement.

[0034] The anti-collision protrusions 5 at the top and bottom of the charging gun body 1 are made of silicone rubber. This material has good elasticity and cushioning performance, and can effectively absorb impact energy and reduce damage caused by direct impact when the charging gun body 1 is accidentally dropped. The dustproof mesh 6 fixedly installed in the heat dissipation holes at the front and rear ends of the charging gun body 1 has good air permeability and dustproof effect, which can not only ensure timely heat dissipation during charging, but also isolate external dust, debris and other foreign objects.

[0035] The charging connector 3 is connected to the built-in charging module 101 via a flexible cable 4. The conductor of the flexible cable 4 is made of multiple strands of high-purity oxygen-free copper wire, and the outer layer is wrapped with an insulation layer and a wear-resistant sheath. The insulation layer is made of polyvinyl chloride (PVC) material, and the sheath is made of polyurethane (PU) material, which ensures the cable's flexibility, electrical insulation performance and wear resistance, and can adapt to the movement requirements of the charging connector 3.

[0036] In terms of circuit control, the built-in microcontroller (MCU) of the charging module is responsible for processing and analyzing the data collected by the current detection unit and the voltage detection unit. When the device starts working, the MCU controls the electromagnet 8 to be energized, and adjusts the current of the electromagnet 8 according to the preset program, thereby controlling the magnetic field strength. The magnetic field generated by the electromagnet 8 attracts the magnetic block 902 of the magnetic drive component 9, which indirectly drives the charging connector 3 to move back and forth inside the charging gun body 1 through the mounting base 901. During the movement of the mounting base 901, the inner snap-fit ​​block 202 of the control sleeve 2 applies a squeezing force to the telescopic block 903, causing it to overcome the elastic force of the compression spring 904 and enter the lifting groove, allowing the mounting base 901 to move normally. When the mounting base 901 moves to the predetermined position, it stops moving due to the obstruction of the stop block 905. At this time, the inner snap-fit ​​block 202 is precisely engaged between the telescopic block 903 and the stop block 905 to achieve positioning and ensure the stable connection of the charging connector 3. During the charging process, the current detection unit and voltage detection unit collect charging current and voltage data in real time and transmit the data to the microcontroller MCU. The microcontroller MCU analyzes and processes the data. If abnormal data is detected, such as overcurrent or overvoltage, the charging circuit is immediately controlled to stop charging.

[0037] Working principle:

[0038] When charging is required, the microcontroller (MCU) first controls the electromagnet 8 to be energized, and the electromagnet 8 generates a magnetic field. Under the repulsive effect of the magnetic field of the electromagnet 8, the magnetic block 902 in the magnetic drive component 9 drives the mounting base 901 to move. Since the mounting base 901 is fixedly installed in the mounting groove of the charging connector 3, it indirectly drives the charging connector 3 to move forward and extend along the guide of the strip slider 7 and the strip groove 203 inside the charging gun body 1, so that the charging operation can be performed normally.

[0039] During the movement of the mounting base 901, the inner locking block 202 of the control sleeve 2 will contact the telescopic block 903. Since the upper end of the telescopic block 903 has a trapezoidal structure that is smaller at the top and larger at the bottom, the inner locking block 202 will apply a squeezing force to the telescopic block 903, causing it to overcome the elastic force of the compression spring 904 and enter the lifting groove. In this way, the mounting base 901 can move normally without obstruction. When the mounting base 901 moves to the predetermined position, it will be blocked by the stop block 905 and stop moving. At this time, the inner locking block 202 is just locked between the telescopic block 903 and the stop block 905, realizing the positioning of the charging connector 3, ensuring that the charging connector 3 is stably connected to the charging equipment, and starting the charging operation.

[0040] During the charging process, the current detection unit and voltage detection unit of the built-in charging module 101 play crucial roles. The current detection unit uses a Hall current sensor to detect the charging current in real time and converts the detected current signal into an electrical signal, which is then transmitted to the microcontroller (MCU). The voltage detection unit measures the charging voltage in real time through a high-precision resistor divider network and an analog-to-digital converter (ADC), and transmits the voltage data to the MCU. The MCU analyzes and processes the collected current and voltage data and compares it with preset normal operating parameter ranges. If the data is within the normal range, the charging process continues. If abnormal data such as overcurrent or overvoltage is detected, the MCU will immediately issue a control signal to stop the charging circuit. At the same time, it will send an alarm message to the user's mobile terminal through indicator light flashing or wireless communication module, alerting the user to the abnormality in the charging process and preventing damage to the charging equipment and battery due to charging failure.

[0041] When charging is finished or the charging connection needs to be disconnected, the microcontroller MCU controls the electromagnet 8 to change the direction of the magnetic field, attract the magnetic block 902, push the mounting base 901 to drive the charging connector 3 to reset, the inner locking block 202 separates from the telescopic block 903 and the stop block 905, and the charging connector 3 returns to the initial position, completing one charging and monitoring process. In case of an accident, it can also be physically disconnected in an emergency to ensure charging safety.

[0042] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
