Description

Technical Field

[0001] This utility model relates to the field of power generation equipment technology, and in particular to a dual-disc linkage efficiency enhancement structure and power generation device. Background Technology

[0002] In the field of mechanical energy conversion and power generation technology, the reciprocating motion generated by linear drive sources such as cylinders is converted into rotary motion through a crank-connecting rod mechanism, thereby driving a generator to generate electricity. In this traditional structure, the cylinder is usually fixed to the frame or the ground, and its piston rod is connected to the crank via a connecting rod, driving the main shaft to rotate.

[0003] However, in some power generation devices, a traditional structure using a single cylinder or multiple cylinders operating in the same phase is employed. When the piston reaches the top (top dead center) and bottom (bottom dead center) of its stroke, the direction of the cylinder's thrust is almost in a straight line with the crank arm, making it impossible to generate effective rotational torque. This phenomenon is called "dead point." This leads to severe periodic fluctuations in the device's output torque. To overcome the "dead point" and smooth the output, a bulky and expensive flywheel must be used. Even so, small fluctuations in rotational speed are still difficult to avoid, which not only cause equipment vibration and noise but also directly affect the stability of power generation quality. Therefore, a dual-disc linkage efficiency-enhancing structure and power generation device are proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a dual-disc linkage efficiency enhancement structure and power generation device, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dual-disc linkage efficiency enhancement structure includes a support frame and two cylinders for driving the structure to move. A rotating shaft is rotatably mounted on the support frame, and a turntable is fixedly connected to both the front and rear sides of the rotating shaft. An eccentric transmission mechanism is provided between the turntable and the cylinder. The eccentric transmission mechanism includes a connecting block eccentrically fixed on the front turntable and the rear turntable. Bolts are threaded onto the connecting block. A collar is fixed to the drive end of both the front cylinder and the rear cylinder. The collar is sleeved on and rotatably connected to the shank of the bolt. There is a 90° phase difference between the power stroke of the rear cylinder connected to the front turntable and the rear turntable. As a further description of the above technical solution: A power generation device with a dual-disc linkage efficiency enhancement structure, the power generation device includes a transmission component linked to the rotating shaft, and a generator driven by the transmission component; As a further description of the above technical solution: The transmission assembly includes a sprocket fixed on the rotating shaft and another sprocket connected to the input end of the generator, and a chain connecting the two sprockets; As a further description of the above technical solution: A gearbox is also provided between the sprocket connected to the input end of the generator and the generator, and the output end of the gearbox is connected to the generator via a synchronous belt. As a further description of the above technical solution: The bottom end of the support frame is fixed with a base, and the front cylinder and the rear cylinder are both mounted on the base through a disassembly and assembly mechanism; As a further description of the above technical solution: The disassembly and assembly mechanism includes a mounting plate connected to the bottom of the cylinder via a mounting groove on the base, and a locking bolt for detachably fixing the mounting plate in the mounting groove. As a further description of the above technical solution: The bottom inner wall of the mounting groove has multiple mounting holes. The locking bolt passes through the mounting plate and is threaded to the mounting holes. The bottom end of the cylinder is fixedly connected to a base plate. A support seat is also rotatably connected between the base plate and the mounting plate.

[0006] This utility model has the following beneficial effects: 1. In this utility model, by setting the power strokes of the front and rear cylinders to a 90° phase difference, torque complementarity is cleverly achieved, eliminating the defect of zero output torque at the "dead point" position in traditional single-cylinder or same-phase structures. This makes the power output of the entire device continuous and stable, without impact or jerking. Therefore, it provides a high-quality rotating power source for the stable operation of the downstream generator, helps to ensure the stability of power output, and reduces the dependence on the large inertia flywheel, thereby reducing the vibration and noise of the device.

[0007] 2. In this utility model, by setting a sliding fit between the mounting groove and the mounting plate, the installation process of the cylinder is made convenient. Especially during maintenance, the cylinder module can be quickly replaced simply by loosening the locking bolts. After reinstallation, the original accuracy can be directly restored without repeating the alignment. This design greatly improves the efficiency of installation and maintenance, reduces labor intensity, and ensures precise alignment between the cylinder and the transmission mechanism, which helps to extend the service life of related components.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a dual-disc linkage efficiency enhancement structure, including a support frame 1 and two cylinders 3 for driving the structure's movement. The support frame 1 provides a stable mounting base for the entire device, and its material can be cast iron or high-strength steel to ensure sufficient rigidity and vibration resistance. A rotating shaft 2 is rotatably mounted on the support frame 1, and a turntable 4 is fixedly connected to both the front and rear sides of the rotating shaft 2. An eccentric transmission mechanism is provided between the turntable 4 and the cylinders 3. The front and rear turntables 4 are fixed to the rotating shaft 2 by key connection or interference fit to ensure that the two rotate synchronously and together form the rotating body.

[0012] The eccentric transmission mechanism includes a connecting block 6 eccentrically fixed on the front turntable 4 and the rear turntable 4. Bolts 7 are threaded onto the connecting block 6. The drive ends of the front cylinder 3 and the rear cylinder 3 are both fixed with collars 5. The collars 5 are fitted and rotatably connected to the rod of the bolts 7. The eccentric installation of the connecting block 6 is the key to realizing the rotational motion. The size of its eccentricity determines the radius of the crank. The bolts 7 are used as crank pins here. The threaded connection facilitates installation and fastening. There is a 90° phase difference between the front cylinder 3 connected on the front turntable 4 and the rear cylinder 3 connected on the rear turntable 4 during their power strokes. The phase difference is achieved by fixing the connecting blocks 6 on the front and rear turntables 4 at an angle of 90° offset from each other during installation. This ensures that when one cylinder 3 is at the "dead point" position with the minimum output torque, the other cylinder 3 is exactly at the position with the maximum output torque. The torque outputs of the two cylinders are perfectly complementary, thereby enabling the rotating shaft 2 to obtain continuous and smooth rotational power.

[0013] Reference Figure 1 , Figure 2 and Figure 3 A dual-disc linkage efficiency-enhancing power generation device includes a transmission assembly linked to a rotating shaft 2, and a generator 13 driven by the transmission assembly. The transmission assembly includes a sprocket 9 fixed on the rotating shaft 2 and another sprocket 9 connected to the input end of the generator 13, and a chain 10 connecting the two sprockets 9. A gearbox 11 is also provided between the sprocket 9 connected to the input end of the generator 13 and the generator 13. The chain drive has the advantages of accurate transmission ratio, strong load-bearing capacity and non-slippage, and is suitable for reliably transmitting the large torque generated by the rotating shaft 2. The output end of the gearbox 11 is connected to the generator 13 through a synchronous belt 12. The function of the gearbox 11 is to increase the speed transmitted from the rotating shaft 2 to match the generator 13 to achieve the rated power generation speed. The synchronous belt 12 connects the gearbox 11 and the generator 13, which can ensure the accuracy of the transmission ratio and avoid speed fluctuations. At the same time, the synchronous belt drive also has the advantages of low noise and shock absorption, which is beneficial to the protection of the generator 13.

[0014] Reference Figure 1 , Figure 3 and Figure 5The support frame 1 has a base 8 fixed to its bottom end. Both the front cylinder 3 and the rear cylinder 3 are mounted on the base 8 via a disassembly and assembly mechanism. The base 8 provides a wide and stable ground foundation and serves as a platform for mounting the cylinder 3. The disassembly and assembly mechanism includes a mounting plate 15 connected to the bottom of the cylinder 3 via a mounting groove 14 opened on the base 8, and a locking bolt for detachably fixing the mounting plate 15 in the mounting groove 14. The side wall of the mounting groove 14 acts as a guide, ensuring that the mounting plate 15 can only move along a predetermined trajectory, facilitating alignment. The bottom inner wall of the mounting groove 14 has multiple mounting holes 16. The locking bolt passes through the mounting plate 15 and is threaded into the mounting holes 16. The design of multiple mounting holes 16 provides locking options at different positions, increasing installation flexibility. The bottom end of the cylinder 3 is fixedly connected to a base plate 18, and a support seat 17 is rotatably connected between the base plate 18 and the mounting plate 15.

[0015] Working principle: When the high-pressure gas drives the piston of the front cylinder 3 to move, the collar 5 fixed at its drive end will push the bolt 7. Since the bolt 7 is eccentrically fixed to the front turntable 4 through the connecting block 6, the linear thrust of the cylinder 3 will be converted into a rotational torque on the turntable 4, thereby driving the rotating shaft 2 to rotate. A 90° phase difference is set between the power stroke of the front cylinder 3 and the rear cylinder 3. When the piston of one cylinder 3 moves to the top or bottom of its stroke, i.e., the "dead point", and the output torque is zero, the piston of the other cylinder 3 is exactly in the middle of its stroke. At this moment, the rotational torque generated is the maximum. Through this torque complementary "relay" method, the two cylinders 3 work together to ensure that the rotating shaft 2 can obtain continuous and stable power input at any time, providing a high-quality, shock-free rotational power source for the stable operation of the subsequent generator 13. In traditional power units, the bottom of the cylinder is usually rigidly mounted on the ground directly or via a simple fixing plate. This method makes it difficult to accurately adjust the alignment of the cylinder and the transmission mechanism during initial installation, and the process of disassembling the cylinder for later maintenance is extremely cumbersome and laborious. In this device, during installation, the mounting plate 15 connected to the bottom of the cylinder 3 is placed into the preset mounting groove 14 on the base 8. The mounting groove 14 acts as a guide rail, allowing the cylinder 3 to be easily finely adjusted in front and behind before locking to achieve precise alignment with the turntable 4. After alignment, the locking bolt is passed through the mounting plate 15 and screwed into the mounting hole 16 at the bottom of the mounting groove 14, which can quickly and firmly fix the cylinder 3. When the cylinder 3 needs to be repaired or replaced, simply loosen the locking bolt, and the entire cylinder module can be easily pulled out along the mounting groove 14. After maintenance, it can be pushed back in to restore the original positional accuracy without repeating the alignment. This design greatly simplifies the installation and disassembly process, shortens maintenance time, and ensures the accuracy of installation.

[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
