Description

Technical Field

[0001] This utility model relates to the field of flywheel energy storage product testing technology, specifically a flywheel energy storage product testing experimental platform. Background Technology

[0002] Flywheel energy storage product testing refers to the systematic testing of the performance, safety, reliability and other indicators of flywheel energy storage systems. It covers multiple aspects such as materials, mechanics, electrical, and environment to ensure that it meets the design requirements and application scenario needs. When testing flywheel energy storage products, a flywheel energy storage product testing experimental platform is required.

[0003] Existing Chinese patent CN219552558U, published on August 18, 2023, discloses a test platform for flywheel energy storage products, relating to the field of flywheel energy storage testing technology. The platform includes a test bench with a guide groove on its upper surface. A first movable base and a second movable base are slidably connected within the guide groove. Supports are symmetrically fixed to the tops of both the first and second movable bases. A rotating shaft is rotatably connected within the two supports. A turntable is fixedly connected to the outer wall of the rotating shaft. Multiple connecting rods are fixedly connected to the outer wall of the turntable. Clamping plates are symmetrically fixed to the outer walls of the multiple connecting rods. Fixed columns are symmetrically fixedly connected within the two clamping plates.

[0004] However, when testing flywheels of different weights, the above-mentioned device requires personnel to adjust it according to the weight of the flywheel to the corresponding number of magnets on the connecting rod before fixing it in place. This is to avoid deviation during testing, which would prevent effective and direct adjustment of the magnetic force and make the adjustment process inconvenient and inefficient.

[0005] Therefore, we propose a novel flywheel energy storage product testing platform to address the aforementioned technical issues. Utility Model Content

[0006] To address the aforementioned issues, a test platform for flywheel energy storage products is provided. This platform solves the problem that, when testing flywheels of different weights, personnel need to adjust the flywheel to the corresponding number of magnetic blocks on the connecting rod before fixing it in place, which prevents displacement during testing and hinders effective and direct adjustment of the magnetic force. This makes the adjustment process inconvenient and inefficient.

[0007] To address the problems in existing technologies, this application provides a test platform for flywheel energy storage products, comprising: The product testing experimental frame has a motor installed on the upper left side by screws, a counter installed on the upper right side of the product testing experimental frame, a flywheel assembly installed between the motor and the counter, and magnetic sleeves sleeved around both ends of the flywheel assembly. A left-side movable adjustment force measuring mechanism is movably installed on the inner left side of the product testing experimental frame. A right-side movable adjustment force measuring mechanism is movably installed on the right side of the product testing experimental frame. Both the right-side and left-side movable adjustment force measuring mechanisms are equipped with offset infrared sensing mechanisms. The offset infrared sensing mechanism, the left-side movable adjustment force measuring mechanism, and the right-side movable adjustment force measuring mechanism are all electrically connected to the control box via connecting lines. The left-side movable adjustment force measuring mechanism includes a first electric telescopic cylinder and a T-shaped movable arm plate. A first coupling is fixedly connected to the end of the telescopic rod of the first electric telescopic cylinder. A connecting rod is fixedly connected to the end of the first coupling away from the telescopic rod. A T-shaped movable arm plate is fixedly connected to the end of the connecting rod away from the first coupling. A plastic sleeve is fixed to the top of the T-shaped movable arm plate. An installation cavity is opened on the top of the plastic sleeve. An electromagnet is fitted on the plastic sleeve. The electromagnet is electrically connected to the control box, and the top of the electromagnet is the N pole.

[0008] Preferably, the right-side moving adjustment force measuring mechanism and the left-side moving adjustment force measuring mechanism have the same structure and are electrically connected to the control box via connecting lines.

[0009] Preferably, the flywheel assembly includes a flywheel body, and horizontally arranged axle rods are fixed symmetrically on both sides of the flywheel body. Magnetic sleeves are fitted on each flywheel axle rod, with the bottom of the magnetic sleeve being the N pole.

[0010] Preferably, the output shaft of the motor is fixedly connected to the end of the flywheel shaft on one side of the flywheel body via a coupling.

[0011] Preferably, the end of the flywheel shaft on the other side of the flywheel body is connected to the counter.

[0012] Preferably, the product testing experimental frame includes a four-hole mounting base plate, the upper surface of which is provided with a T-shaped adjustment groove, a left-side bracket is fixedly connected to the upper left side of the four-hole mounting base plate, and a right-side bracket is fixedly connected to the upper right side of the four-hole mounting base plate.

[0014] Preferably, the centers of the counter and the motor are on the same axis.

[0015] The advantages of this utility model compared to the prior art are: 1. In this utility model, both the electromagnet and the magnetic sleeve are N poles. Utilizing the working principle of magnetic repulsion between like poles, the magnetic sleeve can be suspended above the electromagnet. With the current regulator of the control box, the magnetic force of the electromagnet can be adjusted by changing the current, adapting to the testing needs of flywheel components of different weights. There is no need to manually adjust the position of the magnetic block, which greatly improves the adjustment efficiency and solves the problem of cumbersome adjustment in traditional devices.

[0016] 2. The left and right movable force measuring mechanisms of this utility model have the same structure.

[0019] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0020] See Figures 1-6 As shown, Example 1 This embodiment provides a technical solution: a flywheel energy storage product testing and experimental platform, such as... Figures 1-6 As shown, it includes a product testing experimental frame, a motor 4, a counter 2, a flywheel assembly, a magnetic sleeve 7, a left-side movable adjustment force measuring mechanism, a right-side movable adjustment force measuring mechanism 6, and an offset infrared sensing mechanism.

[0021] A motor 4 is screwed onto the upper left side of the product testing frame, providing the driving force for the test. A counter 2 is fitted onto the upper right side of the frame for easy counting. A flywheel assembly is installed between the motor 4 and the counter 2. The flywheel assembly stores energy up to the maximum number of revolutions through the driving force provided by the motor 4. When stopped, the flywheel assembly, through its stored energy, drives the motor 4 to rotate. The number of revolutions of the flywheel assembly is recorded by the counter 2. By comparing two sets of revolution counts, the energy storage efficiency of flywheel assemblies of different weights can be determined. Magnetic sleeves 7 are fitted around both ends of the flywheel assembly, with the bottom of the magnetic sleeves 7 being the N pole.

[0022] The product testing and experimental frame can support the installation of various components. The product testing and experimental frame includes a four-hole mounting base plate 1, which can be installed in a designated position with screws and can be placed stably. The upper surface of the four-hole mounting base plate 1 has a T-shaped adjustment groove 12. The area of ​​the T-shaped adjustment groove 12 can restrict the movement direction of the left and right movable adjustment force measuring mechanisms 6. A left support 11 is welded to the upper left side of the four-hole mounting base plate 1 to ensure the stability of the left support 11. A right support 13 is welded to the upper right side of the four-hole mounting base plate 1 to ensure the stability of the right support 13. A rubber pad is installed at the connection between the left bracket 11 and the motor 4. The rubber pad increases friction, making the installation more stable and secure, and preventing test deviations caused by the rotation and shaking of the motor 4. The right bracket 13 and the counter 2 are fixed together by a sleeve connection for stable placement, and the counter 2 can perform counting. The centers of counter 2 and motor 4 are on the same axis, which effectively ensures that the flywheel assembly will not deviate when rotating.

[0023] The flywheel assembly includes a flywheel body 5, which is used for energy storage testing of the workpiece. Horizontally mounted axle rods 51 are symmetrically fixed to both sides of the flywheel body 5, and these axle rods 51 can be externally mounted for testing. Each flywheel axle rod 51 is fitted with a magnetic sleeve 7, the position of which can be adjusted to suit different testing requirements. The output shaft of the motor 4 is fixedly connected to the end of the flywheel shaft 51 on one side of the flywheel body 5 via a coupling. When the output shaft of the motor 4 rotates, it can drive the flywheel body 5 to rotate via the flywheel shaft 51 on one side through the coupling, which can reach the maximum number of revolutions of the flywheel body 5 to store energy.

[0024] The end of the flywheel shaft 51 on the other side of the flywheel body 5 is connected to the counter 2. The number of rotations of the flywheel body 5 is synchronized with the number of rotations of the flywheel shaft 51 on the other side, and the number of rotations of the flywheel shaft 51 on the other side is recorded by the counter 2.

[0025] Example 2 This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-5 As shown, to further better realize this utility model, the following arrangement is specifically adopted: the left movable adjustment force measuring mechanism is movably installed on the inner side of the left end of the product testing experimental frame. The left movable adjustment force measuring mechanism can adjust and change its left position as needed. The right side of the left movable adjustment force measuring mechanism is movably installed on the product testing experimental frame. The right movable adjustment force measuring mechanism 6 can adjust and change its position on the right side as needed.

[0026] The right-side and left-side movable adjustment force measuring mechanisms have the same structure, facilitating installation. They are electrically connected to the control box via connecting cables, allowing for start-stop control. The left-side mechanism includes a first electric telescopic cylinder 34 and a T-shaped movable arm plate 3. The first electric telescopic cylinder 34 provides the telescopic force for displacement. The T-shaped movable arm plate 3 can be limited and adjusted within the T-shaped adjustment groove 12 of the four-hole mounting base plate 1. A first coupling 35 is fixedly connected to the end of the telescopic rod of the first electric telescopic cylinder 34. When the telescopic rod of the first electric telescopic cylinder 34 extends, it can drive the first coupling 35 to move inward. A connecting rod 36 is fixedly connected to the end of the first coupling 35 away from the telescopic rod, allowing the connecting rod 36 to move inward. A T-shaped movable arm plate 3 is fixedly connected to the end of the connecting rod 36 away from the first coupling 35. The connecting rod 36 can drive the T-shaped movable arm plate 3 to move inward. A plastic sleeve 31 is fixedly attached to the upper end of the T-shaped movable arm plate 3 with epoxy resin. The position of the plastic sleeve 31 can be changed during the movement of the T-shaped movable arm plate 3. An installation cavity 33 is opened on the top of the plastic sleeve 31. An electromagnet 32 ​​is sleeved on the plastic sleeve 31. The electromagnet 32 ​​can be limited and installed in the plastic sleeve 31 through the area of ​​the installation cavity 33. Electromagnet 32 ​​is electrically connected to the control box, allowing the control box to energize or de-energize electromagnet 32. This causes electromagnet 32 ​​to generate magnetic force (i.e., N pole and S pole), causing the N pole of electromagnet 32 ​​to face upwards. The plastic sleeve 31 then moves electromagnet 32 ​​synchronously to below the magnetic sleeve 7. The N pole radiation area of ​​electromagnet 32 ​​gradually overlaps with the N pole radiation area of ​​magnetic sleeve 7. Utilizing the principle of magnetic repulsion between like poles, the magnetic sleeve levitates above the electromagnet. The current regulator inside the control box can supply different current magnitudes, thus changing the magnetic force of electromagnet 32 ​​according to the current. Adjusting the magnetic force of electromagnet 32 ​​is more convenient, and compared to the comparison device, it does not require further fixation, making testing more convenient and efficient.

[0027] Example 3 This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 2 and Figure 6 As shown, to further better realize this utility model, the following configuration is specifically adopted: an offset infrared sensing mechanism is fixedly installed inside both the right-side moving adjustment force measuring mechanism 6 and the left-side moving adjustment force measuring mechanism. The offset infrared sensing mechanism, the left-side moving adjustment force measuring mechanism and the right-side moving adjustment force measuring mechanism 6 are all electrically connected to the control box through connecting lines. The offset infrared sensing mechanism is used to detect whether the two ends of the flywheel assembly are horizontal.

[0028] The offset infrared sensing mechanism includes a sensor mounting plate 8 fixed to one side of the T-shaped movable arm plate 3 to ensure the stability of the sensor mounting plate 8. An infrared sensor 81, penetrating both its upper and lower ends, is longitudinally fixed on the sensor mounting plate 8. The infrared sensor 81 emits infrared light for distance detection. The extension line of the central axis of the infrared sensor 81 is perpendicular to the central axis of the flywheel shaft 51. The infrared light emitted by the infrared sensor 81 contacts the flywheel shaft 51, thus measuring the positional distance between them. When the two ends of the flywheel shaft 51 are placed parallel, the distance between them is the same. The detection data is transmitted to the control box, and operators can view this data through the control box.

[0029] Working principle: During use, the platform is fixed at the designated test position using the four-hole mounting base plate 1. The left end of the flywheel shaft 51 of the flywheel assembly is connected to the output shaft of the motor 4, and the right end is fitted into the counter 2, ensuring a stable installation. Based on the weight of the flywheel body 5, the current of the electromagnet 32 ​​is adjusted by controlling the control box to change its magnetic force. At the same time, the first electric telescopic cylinder 34 is activated, driving the T-shaped movable arm plate 3 to move along the T-shaped adjustment groove 12, adjusting the relative position of the electromagnet 32 ​​and the magnetic sleeve 7. The flywheel shaft 51 is then suspended and stabilized by the magnetic repulsion.

[0030] During testing, start motor 4 to drive flywheel shaft 51 and flywheel body 5 to rotate. Counter 2 records the number of rotations in real time. During the test, the offset infrared sensing mechanism monitors whether the flywheel is offset. The control box adjusts the magnetic force to ensure test stability. After the test is completed, turn off motor 4 and electromagnet 32, remove the flywheel assembly, and check the test data.

[0031] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
