Technical Field

[0001] This invention relates to the field of electrical engineering technology, specifically to an intelligent power measurement device for generator control. Background Technology

[0002] Currently, with the continuous advancement of my country's modernization process, the demand for electricity is increasing, and the number of large-scale generating units put into operation is also growing. The increase in generating unit capacity and electricity load has led to greater mutual influence between generating units and the power grid.

[0003] Existing intelligent power measurement devices for generator control require the connecting wires on the generator to be wound around the terminals when connecting to the power detector, and then the fixing bolts are tightened with special tools. This process is quite cumbersome. Furthermore, during subsequent generator testing, the generator will generate a certain amount of vibration during operation, which will cause the connecting parts to vibrate. Due to the vibration, the fixing bolts may loosen, resulting in poor contact and abnormal test data. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent power measurement device for generator control, which solves the problem mentioned in the background art. In existing intelligent power measurement devices for generator control, the connection wires on the generator need to be wound around the terminals and then tightened with special tools when connecting to the power detector. This process is cumbersome. Furthermore, during subsequent generator testing, the generator will generate a certain amount of vibration during operation, which will cause the connecting parts to vibrate. Due to the vibration, the fixing bolts may loosen, resulting in poor contact and abnormal test data.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent power measurement device for generator control, comprising a generator, a power detector disposed on one side of the generator, a connection hole provided on one side of the power detector, a connecting wire fixedly connected to the generator, the other end of the connecting wire being used to connect to the power detector, a connecting post fixedly connected inside the power detector, the connecting post being located on one side of the connection hole, a rotating plate sleeved on the connecting post, one end of the rotating plate being rotatably connected to the connecting post, and a fixing post fixedly connected to the other end of the rotating plate, the fixing post being used to wind the connecting wire around the connecting post;

[0006] When the device connects the connecting wire on the generator to the power detector, it can automatically wind the connecting wire around the connecting post under the action of the fixing post.

[0007] Furthermore, a sliding column is slidably connected inside the fixed column, the sliding column passes through the rotating plate, and a sliding ball is fixedly connected to one end of the sliding column.

[0008] Furthermore, a sliding rod is slidably connected to the other end of the sliding column, a spring is provided between the sliding column and the sliding rod, and a lower pressure ring is fixedly connected to the other end of the sliding rod. The lower pressure ring is sleeved on the connecting column and is slidably connected to the connecting column.

[0009] Furthermore, a contact arc surface is provided on one side of the pressure ring, and an inclined extrusion groove is provided on one side of the pressure ring. The contact arc surface and the inclined extrusion groove are used to guide the connecting line.

[0010] Furthermore, a gear is fixedly connected to the lower side of the rotating plate, the gear is sleeved on the connecting column, and the gear is rotatably connected to the connecting column.

[0011] Furthermore, the power detector has a guide arc groove inside, which is used to slide with the fixed post and guide the fixed post.

[0012] Furthermore, the power detector has an arc-shaped groove inside, the sliding column is slidably connected to the arc-shaped groove, and a guide groove is provided on the side wall of the arc-shaped groove for guiding the sliding ball.

[0013] Furthermore, a hydraulic rod is installed inside the power detector, and a fixed rod is fixedly connected to the power output end of the hydraulic rod. A rack is fixedly connected to one end of the fixed rod, and the rack is used to mesh with the gear.

[0014] Furthermore, a limiting groove is provided on the fixed rod, and a limiting rod is slidably connected inside the limiting groove. The limiting rod is slidably connected to a first straight groove, an oblique groove, and a second straight groove. The first straight groove, the oblique groove, and the second straight groove are fixedly connected to each other. The first straight groove, the oblique groove, and the second straight groove are formed inside the power detector.

[0015] Furthermore, an abutment block is fixedly connected to the other end of the limiting rod, and the abutment block is used to squeeze the connecting line.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0017] I. This invention automatically completes the tight winding, arc-surface pressing, and wire end locking of the connecting wire through hydraulically driven integrated mechanical linkage. This process ensures a large contact area and stable and uniform pressure between the connecting wire and the connecting post, fundamentally eliminating problems such as increased contact resistance, overheating, or signal attenuation caused by poor contact. This provides a stable and high-quality electrical signal input foundation for high-precision electrical energy measurement at the back end.

[0018] Second, this invention allows for the one-click completion of the entire process from wiring to fastening by inserting the connecting wire and activating the hydraulic rod. This design transforms the tedious and skillful wiring operations (such as screwing and crimping) that traditionally rely on professionals to perform manually into automated and standardized mechanical actions, significantly improving operational efficiency, reducing reliance on the skill level of operators, and making the connection work faster and less labor-intensive.

[0019] Third, the entire set of mechanical actions of this invention is precisely controlled by a preset trajectory groove. This standardized connection process eliminates the uncertainty of human operation, so that each test can obtain repeatable and reliable electrical connection quality, ensuring the consistency and comparability of test results.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to embodiments.

[0032] Example: An intelligent power measurement device for generator control, such as... Figures 1-8 As shown, the device includes a generator 1, a power detector 2 on one side of the generator 1, a connection hole 3 on one side of the power detector 2, a connecting wire 4 fixedly connected to the generator 1, the connecting wire 4 being a copper wire with a certain rigidity (which can be freely selected by professionals in this field), the other end of the connecting wire 4 being used to connect to the power detector 2, a connecting post 5 fixedly connected inside the power detector 2, the connecting post 5 being located on one side of the connection hole 3, a rotating plate 6 being sleeved on the connecting post 5, one end of the rotating plate 6 being rotatably connected to the connecting post 5, and a fixing post 7 fixedly connected to the other end of the rotating plate 6, the fixing post 7 being used to wind the connecting wire 4 around the connecting post 5. Through the design of the rotating plate 6 and the fixing post 7, the connecting wire 4 can be wound around the connecting post 5 when the rotating plate 6 rotates around the connecting post 5, so that the generator 1 and the power detector 2 can be connected.

[0033] The power detector 2 contains a signal input card, a signal processing card, and a human-machine interface card. The signal input card has multiple internal PT1 modules, multiple internal measurement CT modules, an internal CT module, and an internal PT module. The signal processing card has a synchronous sampling chip, a first microprocessor, and an AD sampling chip that converts AC signals into DC signals and sends them to the first microprocessor. The first microprocessor samples, calculates, analyzes, and statistically analyzes the signals to obtain power quality data. The internal PT1 modules are used to receive and detect the three-phase voltage signals passed through the external PT1. The internal measurement CT modules are used to receive and detect the three-phase current signals passed through the external measurement CT. Through seamless current switching technology, the influence of excessive current or non-periodic components in the measuring current transformer, which could cause the transmitter to fail to output power correctly, can be effectively avoided.

[0034] The seamless current switching technology in this invention is an advanced technology that maintains the continuity and stability of output or measurement when switching between ranges or modes in current measurement or power output. The core of this technology lies in its ability to smoothly switch from one range or mode to another without interrupting measurement or output. This is typically achieved through the following methods:

[0035] Multi-range parallel processing: Multiple ranges are set inside the sensor or measuring device, and these ranges can work simultaneously, automatically selecting the most suitable range for processing in real time according to the magnitude of the input signal.

[0036] High-precision conversion algorithm: Advanced algorithms are used to ensure that the output or measured value remains continuous and stable during range switching, avoiding jumps or distortions.

[0037] Hardware optimization: By optimizing the hardware design of sensors and measurement circuits, response time and interference during range switching are reduced, thereby improving overall performance.

[0038] When the device connects the connecting wire 4 on the generator 1 to the power detector 2, it can automatically wrap the connecting wire 4 around the connecting post 5 under the action of the fixing post 7.

[0039] The fixed column 7 has a sliding column 8 inside, which passes through the rotating plate 6. One end of the sliding column 8 is fixedly connected to a sliding ball 9. The design of the sliding ball 9 allows it to guide the sliding column 8 when it moves.

[0040] A sliding rod 10 is slidably connected to the other end of the sliding column 8. A spring 11 is provided between the sliding column 8 and the sliding rod 10. A lower pressure ring 12 is fixedly connected to the other end of the sliding rod 10. The lower pressure ring 12 is sleeved on the connecting column 5 and is slidably connected to the connecting column 5. Through the design of the spring 11, the sliding column 8 drives the sliding rod 10 and the lower pressure ring 12 to slide downward. After the lower pressure ring 12 presses the connecting line 4 tightly, the spring 11 deforms as it continues to slide downward, and there will be no jamming.

[0041] One side of the pressure ring 12 is provided with an abutting arc surface 13. Through the design of the pressure ring 12 and the abutting arc surface 13, when the pressure ring 12 slides down, it can use the abutting arc surface 13 to abut the connecting wire 4 towards the connecting post 5, so that the connecting wire 4 can make tight contact with the connecting post 5 and prevent poor contact. One side of the pressure ring 12 is provided with an inclined extrusion groove 14. The abutting arc surface 13 and the inclined extrusion groove 14 are used to guide the connecting wire 4. At the same time, through the design of the inclined extrusion groove 14, the wire end of the connecting wire 4 can be fixed, so that the connecting wire 4 can make tighter contact with the connecting post 5.

[0042] A gear 15 is fixedly connected to the lower side of the rotating plate 6. The gear 15 is sleeved on the connecting column 5 and is rotatably connected to the connecting column 5. Through the design of the gear 15, the subsequent gear 15 can drive the rotating plate 6 and the fixed column 7 to rotate together during the rotation process.

[0043] The power detector 2 has a guide arc groove 16 inside. The guide arc groove 16 is used to slide and connect with the fixed post 7. The guide arc groove 16 is used to guide the fixed post 7. Through the design of the guide arc groove 16, the position of the fixed post 7 can be restricted to prevent the fixed post 7 from deviating during the sliding process.

[0044] The power detector 2 has an arc-shaped groove 17 inside, and the sliding column 8 is slidably connected to the arc-shaped groove 17. A guide groove 18 is provided on the side wall of the arc-shaped groove 17. The guide groove 18 is used to guide the sliding ball 9. (See...) Figure 6 The guide chute 18 has one section as a straight chute and one section as an inclined chute.

[0045] The power detector 2 has a hydraulic rod 19 installed inside. The power output end of the hydraulic rod 19 is fixedly connected to a fixed rod 20. One end of the fixed rod 20 is fixedly connected to a rack 21. The hydraulic rod 19 is designed to provide power to the rack 21. The rack 21 is used to mesh with the gear 15. By sliding the rack 21, the gear 15 can be driven to rotate.

[0046] A limiting groove 22 is provided on the fixed rod 20. A limiting rod 23 is slidably connected inside the limiting groove 22. A first straight groove 24, an oblique groove 25, and a second straight groove 26 are slidably connected to the limiting rod 23. The first straight groove 24, the oblique groove 25, and the second straight groove 26 are fixedly connected to each other. The first straight groove 24, the oblique groove 25, and the second straight groove 26 are provided inside the power detector 2.

[0047] The other end of the limiting rod 23 is fixedly connected to an abutment block 27, which is used to squeeze the connecting wire 4. Through the design of the abutment block 27, the end of the connecting wire 4 can be squeezed, so that the connecting wire 4 can be more firmly wrapped around the connecting post 5.

[0048] When generator 1 needs to be tested, insert the end of the connecting wire 4 on generator 1 into the inside of the connecting hole 3 so that the end of the connecting wire 4 can be inserted into the inside of the power detector 2. At this time, the connecting wire 4 is located between the connecting post 5 and the fixed post 7. Then, start the hydraulic rod 19 so that the hydraulic rod 19 can drive the fixed rod 20 and the rack 21 to slide. The rack 21 can drive the gear 15 so that the gear 15 can rotate. When the gear 15 rotates, it can drive the rotating plate 6 to rotate together, so that the rotating plate 6 can rotate around the connecting post 5. When the rotating plate 6 rotates, it can drive the fixed post 7, the sliding post 8, the sliding ball 9, the sliding rod 10, the spring 11 and the lower pressure ring 12 to move together, so that the lower pressure ring 12 can rotate on the connecting post 5.

[0049] When the rotating plate 6 rotates, it drives the fixed column 7 to rotate around the connecting column 5. At this time, the fixed column 7 slides inside the guide arc groove 16, so that the fixed column 7 can squeeze and abut against the connecting line 4 between the connecting column 5 and the fixed column 7, so that the connecting line 4 can be wrapped around the connecting column 5, and the connecting line 4 can be connected to the power detector 2.

[0050] As the rotating plate 6 drives the fixed column 7 to rotate around the connecting column 5, the sliding column 8 slides within the arc groove 17, while the sliding ball 9 slides within the straight groove of the guide groove 18. When the end of the connecting line 4 is about to wrap around the connecting column 5, the sliding ball 9 slides to the inclined groove of the guide groove 18. Guided by the inclined groove of the guide groove 18, [the following text is missing]. Figure 6The sliding ball 9 will drive the sliding column 8 to slide downwards together. As the sliding column 8 slides downwards, under the action of the spring 11, it will pull the sliding rod 10 and the pressure ring 12 to slide downwards together. As the pressure ring 12 slides downwards, the contact arc surface 13 on the pressure ring 12 will contact and squeeze the connecting wire 4, so that the pressure ring 12 can move towards the connecting column 5, so that the connecting wire 4 can be tightly attached to the surface of the connecting column 5. At the same time, under the guidance of the inclined extrusion groove 14, the end of the connecting wire 4 after wrapping around the connecting column 5 can be stuck in the inclined extrusion groove 14 together with the connecting wire 4 body, further enabling the connecting wire 4 to have close contact with the connecting column 5.

[0051] It should be noted that if the diameter of the connecting wire 4 is large, the lower pressure ring 12 has already pressed the connecting wire 4 tightly. At this time, when the sliding ball 9 continues to slide down, the spring 11 will deform as the force increases. At this time, the sliding rod 10 slides inside the sliding column 8. This design can prevent jamming. In addition, the spring 11 will not deform before being pressed tightly. The maximum diameter of the connecting wire 4 does not exceed the angle of the opening of the contact arc surface 13.

[0052] While the hydraulic rod 19 pushes the fixed rod 20 to slide, it can also drive the limiting rod 23 to slide together. The limiting rod 23 slides in the first straight groove 24. As it continues to push, when the limiting rod 23 slides into the inclined groove 25, under the guidance of the inclined groove 25, one end of the limiting rod 23 will slide in the limiting groove 22, so that the limiting rod 23 can drive the abutment block 27 to move together. Through this design, it is possible to prevent the abutment block 27 from blocking the end of the connecting wire 4 when the connecting wire 4 is wrapped around the connecting post 5.

[0053] Subsequently, the limiting rod 23 slides inside the second straight groove 26. As the hydraulic rod 19 continues to push, the abutment block 27 can squeeze the end of the connecting wire 4, which can prevent the end of the connecting wire 4 from sticking up, so that the end of the connecting wire 4 can be in tight contact with the body of the connecting wire 4, and further make the connecting wire 4 in tight contact with the connecting post 5.

[0054] When it is necessary to remove the connecting wire 4 from the power detector 2, simply activate the hydraulic rod 19 to pull it back, so that the various structures inside the power detector 2 can return to their initial state, and then the connecting wire 4 can be pulled out directly.

[0055] In this embodiment: when it is necessary to connect the connecting wire 4 on the generator 1 to the power detector 2, after inserting the connecting wire 4 into the connecting hole 3 to a sufficient length, the hydraulic rod 19 is activated, causing the hydraulic rod 19 to drive the rack 21, which in turn drives the gear 15 to rotate. As the gear 15 rotates, it drives the rotating plate 6 and the fixed column 7 to rotate around the connecting column 5, allowing the connecting wire 4 to wrap around the connecting column 5, thus establishing a stable connection between the generator 1 and the power detector 2. While the fixed column 7 rotates, the design of the sliding ball 9 and the guide groove 18 allows the sliding ball 9 to pull the sliding column 8 and the lower pressure ring 12. Pressing down, and with the design of the contact arc surface 13, the connecting line 4 can be tightly attached to the connecting post 5, further ensuring that the connecting line 4 can make close contact with the connecting post 5; when the hydraulic rod 19 is activated, it will drive the fixed rod 20 and the limiting rod 23 to move together. Guided by the first straight slide groove 24, the inclined slide groove 25 and the second straight slide groove 26, the limiting rod 23 can drive the contact block 27 to squeeze and abut against the end of the connecting line 4, which can prevent the end of the connecting line 4 from lifting up, so that the end of the connecting line 4 can make close contact with the body of the connecting line 4, and further ensure that the connecting line 4 can make close contact with the connecting post 5.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
