Description

Technical Field

Traditional coordinate measuring machines are inefficient and require the introduction of equipment such as laser trackers. The assembly time for a single flywheel is 2-3 times longer than that for a single structure.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of a preferred embodiment of a combined flywheel energy storage device provided by this utility model; Figure 2 for Figure 1 The diagram shows an enlarged view of part A. A combined flywheel energy storage device includes: a flywheel disk 1, a moving mechanism 2 disposed on the surface of the flywheel disk 1, and a moving block 21 movably mounted on the surface of the flywheel disk 1; The fixing mechanism 3 includes a toothed block 31, which is movably mounted on the surface of the flywheel disk 1, and the number of moving blocks 21 is multiple.

[0017] The function of the moving mechanism 2 is to change the energy storage capacity of the flywheel 1 by changing the mass at different positions of the flywheel 1. There are multiple moving blocks 21, which are arranged in a circular array on the surface of the flywheel 1 and are arc-shaped. By changing the circumference of the multiple moving blocks 21, the position of the moving blocks 21 on the surface of the flywheel 1 is changed. According to the rotational inertia, the kinetic energy formula and the relationship between the mass distance from the axis and the rotational kinetic energy, it can be seen that the farther the mass is from the axis, the greater the kinetic energy at the same angular velocity. The function of the fixing mechanism 3 is to adjust the position of the moving blocks 21 and fix the moving blocks 21. There are multiple toothed blocks 31, which are arranged in a circular array and are composed of teeth on the outer surface of an arc-shaped block.

[0018] The surface of the flywheel 1 is connected to a limiting member 22, and one end of the moving block 21 is movably connected to the surface of the limiting member 22. The limiting member 22 is used to limit the movement of the moving block 21.

[0019] The number of limiting members 22 is the same as the number of moving blocks 21, and they are fixedly connected to the surface of the flywheel disk 1 in a one-to-one correspondence with the moving blocks 21. They can be sliding grooves and sliding rods, etc., preferably sliding grooves. A slider is fixedly connected to one end of the surface of each moving block 21. The sliders are slidably embedded in the interior of the corresponding limiting member 22. The movement of the moving block 21 is limited by the connection between the slider and the limiting member 22.

[0020] A push-pull rod 23 is connected to the surface of the movable block 21. The push-pull rod 23 is used to connect and drive the movable block 21. The other end of the push-pull rod 23 is movably connected to the surface of the rotating disk 24.

[0021] The number of push-pull rods 23 is the same as the number of moving blocks 21. One end of each rod is rotatably connected to the surface of the corresponding moving block 21. The rotating disk 24 is rotatably connected to the surface of the flywheel disk 1 on the same axis as the flywheel disk 1. The other end of the push-pull rods 23 is movably connected to the surface of the rotating disk 24 in a circular array.

[0022] A rotating disk 24 is movably mounted on the surface of the flywheel disk 1, and the rotating disk 24 is used to drive the other end of the push-pull rod 23 to rotate.

[0023] By rotating the rotating disk 24, the other ends of multiple push-pull rods 23 are rotated, which can limit the position of the limiting member 22 and the slider. One end of the push-pull rod 23 can give the moving block 21 a pushing or pulling force, thereby changing the position of the moving block 21.

[0024] The toothed block 31 is movably connected to the surface of the rotating disk 24, the toothed ring 32 is fixedly connected to the surface of the flywheel disk 1, and the toothed block 31 is connected to the inner surface of the toothed ring 32.

[0025] There are multiple toothed blocks 31, which are movably connected to the surface of the rotating disk 24 in a circumferential array. The rotating disk 24 has the same number of grooves in a circumferential array on its surface. Each toothed block 31 has a slider fixedly connected to its surface. The slider is embedded in the corresponding groove and a spring is fixedly connected to its surface. The toothed ring 32 is a ring-shaped sleeve with teeth connected in an array on its inner surface. The rotating disk 24 is movably installed inside the toothed ring 32. Without the limiting effect of the fixed ring 33, the spring pushes the toothed block 31, causing it to disengage from the toothed ring 32. Thus, the teeth on the surfaces of the toothed block 31 and the toothed ring 32 are no longer meshed, and the rotating disk 24 loses its fixing force.

[0026] A fixing ring 33 is connected to the surface of the rotating disk 24, and a bolt 34 is connected to the surface of the fixing ring 33. The fixing ring 33 is used to limit and fix the tooth block 31, and the bolt 34 is used to fix the fixing ring 33.

[0027] The fixing ring 33 is ring-shaped and can be fitted onto the outer surface of the flywheel disc 1 flange. Its width is just enough to fit between the flange and the toothed block 31. The surface of the fixing ring 33 has multiple threaded holes. By threading the bolt 34 into the fixing ring 33 and the rotating disc 24, the fixing ring 33 can be fixed on the surface of the rotating disc 24, that is, the toothed block 31 and the toothed ring 32 can be meshed and fixed.

[0028] The working principle of the combined flywheel energy storage device provided by this utility model is as follows: When adjusting the energy storage capacity of the flywheel disk 1, first unscrew the bolt 34 from the internal thread of the retaining ring 33, then remove the retaining ring 33 from the surface of the moving block 21. Under the action of the spring, the toothed block 31 disengages from the surface of the toothed ring 32, thus the rotating disk 24 loses its fixing force. Then rotate the rotating disk 24, which in turn drives the other end of the push-pull rod 23 to rotate. At the connection limit between the moving block 21 and the limiting member 22, the angle of the push-pull rod 23 changes, and the other end pushes and pulls the moving block 21. Based on the moment of inertia, kinetic energy formula, and physical principles, the closer the moving block 21 is to the flywheel disk... The larger the storage size of the edge, the more the moving block 21 moves to the appropriate position. Then, the fixing ring 33 is fitted onto the middle flange of the flywheel disk 1 and connected to the surface of the rotating disk 24. Under the push limit of the fixing ring 33, the tooth block 31 moves outward and meshes with the inner surface of the tooth ring 32. Then, the bolt 34 is threaded into the inside of the fixing ring 33, so that the fixing ring 33 is fixed inside the rotating disk 24. Restricted by the fixing ring 33, the tooth block 31 meshes with the surface of the tooth ring 32 and is fixed, so the rotating disk 24 is fixed and the push-pull rod 23 cannot rotate. The moving block 21 is then fixed on the surface of the flywheel disk 1.

[0029] Compared with related technologies, the combined flywheel energy storage device provided by this utility model has the following beneficial effects: This utility model provides a combined flywheel energy storage device. Through the connection and transmission of the fixing mechanism 3, multiple moving blocks 21 can be driven to move on the surface and can be fixed, thereby changing the mass of different positions on the surface of the flywheel disk 1 and realizing the change of the energy storage capacity of the flywheel disk 1. There is no need to install and connect multiple flywheel disks 1, and the operation is convenient.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
