[0017] 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.

[0018] In the embodiments, by Figure 1 and Figure 2 A buffer flow collection and guiding device is provided, comprising a conduit 1, the top end of which is connected to two flow collection pipes 3 via a flange 2. The lower halves of the two flow collection pipes 3 are interconnected. A retaining frame 4 is provided on the outer side of each of the two flow collection pipes 3. The top ends of the two retaining frames 4 are respectively fixedly connected to two rotating seats 5. The two rotating seats 5 are fixedly connected to each other via a connecting rod 6. A rotating shaft 7 is rotatably connected to each of the opposite sides of the two rotating seats 5. A baffle plate 8 is fixedly connected between the two rotating shafts 7. The baffle plate 8 is located on the inner side of the two flow collection pipes 3 and is adapted to the inner wall of the flow collection pipes 3. A driving mechanism 9 for driving the baffle plate 8 to rotate is provided on the flange 2.

[0019] With the above setup, fluid enters the device from the top inlets of the two manifolds 3. Since the lower halves of the manifolds 3 are interconnected, some fluid naturally converges through the connecting area upon entry, initially achieving balanced flow distribution. The diameter of the manifolds 3 gradually narrows from top to bottom, and the converging section design further concentrates the fluid, reducing inlet turbulence. The drive mechanism 9 controls the rotation angle of the baffle plate 8 through the rotating shaft 7, adjusting its position within the manifolds 3. The baffle plate 8 and the inner wall of the manifolds 3 form a narrow flow channel, increasing local resistance and forcing the fluid to slow down and flow evenly. The connecting rod 6 ensures that the rotating seats 5 on both sides move synchronously, avoiding flow deviation or vibration. The change in the rotation angle of the baffle plate 8 directly changes the fluid dynamics. The flow distribution is such that when the baffle plate 8 partially blocks the flow channel, the fluid impacts the surface of the baffle plate 8, and the energy is dissipated through the rigid support of the structural damping frame 4 and the rotating seat 5, thus achieving a buffering function. The guide surface of the baffle plate 8 guides the fluid to the central area of ​​the manifold 3, preventing the generation of local eddies and ensuring that the flow direction is consistent with the axis of the conduit 1. After buffering and guiding, the fluid flows into the conduit 1 through the lower half of the manifold 3. The straight structure of the conduit 1 further stabilizes the flow field, reduces pressure pulsation, and outputs to the downstream system. The rotation angle of the baffle plate 8 can be adjusted in real time by the drive mechanism 9, which can not only reduce the fluid impact energy, but also flexibly control the flow rate according to the working conditions, making it highly adaptable.

[0020] Reference Figure 1 and Figure 2 The drive mechanism 9 includes an extension arm 91. The extension arm 91 is mounted on the top of the flange 2. The outer side of the extension arm 91 is hinged to a mounting base 92. The bottom end of the mounting base 92 is bolted to a cylinder 93. The inner side of the cylinder 93 is slidably connected to a cylinder push rod 94. The top of the cylinder push rod 94 is mounted to a top head 95. The inner side of the top head 95 has a through hole 96. The inner side of the through hole 96 is fitted with a U-shaped rod 97. The two ends of the U-shaped rod 97 are respectively fixedly connected to the inner sides of two rotating shafts 7.

[0021] With the above-mentioned structure, the cylinder 93 is powered by an external air source or hydraulic system. The cylinder push rod 94 moves linearly along the axis inside the cylinder 93. The top head 95 of the cylinder push rod 94 moves synchronously with the push rod. The U-shaped rod 97 in its through hole 96 is pushed or pulled back. The two ends of the U-shaped rod 97 are respectively fixed to the inner sides of the two rotating shafts 7. When the top head 95 extends and retracts with the cylinder push rod 94, the U-shaped rod 97 drives the rotating shaft 7 to rotate around its own axis. The rigid connection of the U-shaped rod 97 ensures that the rotation angles of the two rotating shafts 7 are completely synchronized, preventing the baffle plate 8 from getting stuck due to uneven force on both sides. The rotation of the rotating shaft 7 directly drives the baffle plate 8 to swing in the manifold 3. The opening and closing angle of the baffle plate 8 can be precisely adjusted by the stroke length of the cylinder 93. The hinge design of the extension arm 91 and the mounting base 92 allows the cylinder 93 to swing slightly during the movement, adapting to the trajectory changes when the rotating shaft 7 rotates, reducing structural stress. By controlling the extension and retraction of the cylinder 93, the degree of expansion of the baffle plate 8 can be precisely set to adapt to different flow rate, pressure or fluid characteristic requirements.

[0022] Reference Figure 1 and Figure 2 The diameter of the through hole 96 is larger than the diameter of the U-shaped rod 97;

[0023] Through the above structural design, the gap design allows a small amount of grease to remain in the through hole 96, ensuring long-term lubrication without frequent maintenance. When the cylinder 93 moves rapidly or fluid impact causes the U-shaped rod 97 to be momentarily stressed, the spare space in the through hole 96 provides a slight oscillation buffer for the U-shaped rod 97, preventing rigid impact from being transmitted to the rotating shaft 7 and the baffle plate 8, and protecting key structures such as the rotating seat 5 and the connecting rod 6 from vibration damage.
