Description

Technical Field

[0001] This utility model relates to the field of non-smooth surface structures, specifically a wear-resistant biomimetic structure that can be adaptively adjusted. Background Technology

[0002] In modern industry, fluid equipment has long faced surface damage problems caused by fluid erosion, particle wear, and cavitation effects. This type of wear significantly reduces the service life of fluid equipment, affects the energy efficiency of fluid transportation, and results in high maintenance and replacement costs. Wear problems severely restrict the development of major equipment such as ships in a low-energy-consumption and sustainable manner. Therefore, it is imperative to develop a new anti-wear technology suitable for fluid equipment.

[0003] In nature, many organisms achieve highly efficient wear resistance through non-smooth surface structures, providing important insights for the engineering field. For example, the surface of pangolin scales consists of multiple layers of oriented microgrooves, which can disperse external loads and reduce contact stress during soil excavation through structural deformation; the nacreous layer of seashells induces crack deflection through a microscopic "brick-and-mortar" structure, significantly delaying material fracture; and the non-smooth texture on the skin surface of desert lizards reduces frictional loss by guiding the flow of sand grains. Based on these biological characteristics, researchers have conducted biomimetic research and successfully developed a series of biomimetic non-smooth structures with excellent wear resistance.

[0004] While biomimetic non-smooth structures have shown potential in the field of wear resistance, existing technologies still have many limitations. Most engineering biomimetic structures use fixed geometric parameters (such as groove depth and protrusion height), and their wear resistance performance is highly dependent on preset operating conditions. The inability to change the wear-resistant structure in real time severely restricts their efficiency. Therefore, there is an urgent need for an adaptive biomimetic non-smooth structure that can adjust its morphological parameters in real time according to fluid characteristics to overcome the static limitations of existing technologies and achieve long-term wear resistance under dynamic operating conditions. Utility Model Content

[0005] This invention addresses the current limitations of existing technologies in adjusting the parameters of flow guiding structures by providing a wear-resistant biomimetic structure that can adaptively adjust the depth and diameter of the flow guiding structure.

[0006] An adaptively adjustable wear-resistant biomimetic structure, comprising:

[0007] A plate body, wherein the plate body is provided with multiple mounting slots;

[0008] A flow guide plate is disposed in the mounting groove, and flow guide grooves are formed at both ends of the flow guide plate to guide the flow of fluid;

[0009] An adjustment mechanism is provided to dynamically adjust the height of the guide plate and the opening size of the guide channel to adapt to different fluid conditions.

[0010] A driving device, which is connected to the adjustment mechanism, is used to drive the adjustment mechanism to achieve dynamic adjustment of the guide plate;

[0011] Furthermore, the adjustment mechanism includes a threaded rod and a movable plate. The threads on both sides of the center point of the horizontal axial section of the threaded rod have opposite directions of rotation. The movable plate is threaded onto both ends of the threaded rod. The movable plate is connected to the guide plate through a traction plate. The rotation of the threaded rod drives the movable plate to move in opposite directions, thereby adjusting the height of the guide plate.

[0012] Furthermore, the driving device includes a motor and a shaft. The output shaft of the motor is fixedly connected to the shaft, and one end of the shaft is fixedly connected to the threaded rod. The motor drives the threaded rod to rotate, thereby realizing the dynamic adjustment of the guide plate.

[0013] Furthermore, it also includes a quick-installation structure, which is used to quickly install and remove the deflector plate, facilitating maintenance and replacement.

[0014] Furthermore, the quick-installation structure includes an insert block and a locking block. The bottom of the guide plate is provided with an insert block, and the connecting block is provided with an assembly groove corresponding to the insert block. The insert block is slidably inserted into the assembly groove. Push rods are slidably inserted at both ends of the connecting block, and a locking block is fixedly connected to one end of the push rod. The locking block cooperates with the locking groove on the insert block to realize the quick installation and removal of the guide plate.

[0015] Furthermore, the guide plate has wedge-shaped blocks at both ends. The wedge-shaped blocks have a structure that is wider at the top and narrower at the bottom. The wedge-shaped blocks can be horizontally displaced when the guide plate moves downward, thereby adaptively adjusting the opening diameter of the guide groove.

[0016] Furthermore, the wedge block is connected to the receiving groove in the mounting groove via a limiting rod. A spring is sleeved on the limiting rod, and the two ends of the spring are fixedly connected to the inner wall of the receiving groove and the wedge block, respectively. The rebound force of the spring can cause the wedge block to automatically return to its initial position when the guide plate separates from the wedge block.

[0017] This invention boasts advantages such as structural innovation, strong dynamic adaptability, precise adjustment, easy disassembly, and excellent expandability. The device employs a unique collaborative design of a guide plate and a wedge block. Through a motor-driven reverse-threaded rod, the moving plates move in opposite directions, enabling flexible adjustment of the guide plate height and dynamically changing the depth of the guide channel. Simultaneously, as the guide plate descends, it presses against the wedge block, and combined with a spring reset system, the opening diameter of the guide channel can be adaptively adjusted to effectively match the requirements of different fluid conditions.

[0018] Compared to traditional biomimetic structures with fixed geometric parameters, this device can adjust its morphological parameters in real time according to fluid characteristics, maintaining its long-term wear resistance. Furthermore, by synchronously driving multiple sets of threaded rods through connecting rods, multiple guide vanes can be adjusted in tandem, offering strong scalability and modular integration onto the surface of large fluid equipment. This provides an efficient solution for low-energy consumption and sustainable operation of equipment such as water turbines, steam turbines, and ships. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to these embodiments.

[0025] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions.

[0026] The technical solution provided by this utility model is as follows:

[0027] This utility model includes a plate body with multiple mounting slots. Each mounting slot contains a guide plate, the two ends of which are bent upwards to form a guide groove. Each mounting slot contains a threaded rod rotatably connected to a threaded rod. The threads on both sides of the center point of the horizontal axial section of the threaded rod are arranged in opposite directions. Each end of the threaded rod is threaded with a movable plate. The top of the movable plate is rotatably connected to a traction plate. The top of the traction plate is rotatably connected to a connecting block. The connecting block is fixedly connected to the bottom of the guide plate. The threaded rods in the mounting slots are fixedly connected to each other by connecting rods. A motor is fixedly connected to the outer wall of one end of the plate body. The output shaft of the motor is fixedly connected to a shaft rod. One end of the shaft rod is fixedly connected to one of the threaded rods.

[0028] The quick-installation structure includes an insert block on the bottom of the guide plate, an assembly groove corresponding to the insert block on the connecting block, the insert block being slidably inserted into the assembly groove, push rods being slidably inserted at both ends of the connecting block, a locking block being fixedly connected to one end of the push rod, the top of one end of the locking block being inclined, a locking groove corresponding to the locking block being provided on the side wall of the insert block, a positioning sleeve being fixedly sleeved at one end of the push rod, and springs being fixedly connected between both ends of the positioning sleeve and the connecting block.

[0029] Furthermore, the inner walls on both sides of the mounting groove are provided with communicating receiving grooves, and one side of the receiving groove is provided with a communicating slot. A limiting rod is slidably inserted into the slot, and a wedge block is fixedly connected to one end of the limiting rod.

[0030] Furthermore, the wedge-shaped block is designed with a structure that is wider at the top and narrower at the bottom;

[0031] Furthermore, a spring is fitted onto the limiting rod, and the two ends of the spring are fixedly connected to the inner wall of the receiving groove and the wedge block, respectively.

[0032] like Figure 1 and Figure 3As shown, this embodiment includes a plate 1 with multiple mounting slots 12. Each mounting slot contains a guide plate 10. The two ends of the guide plate 10 are bent upwards to form guide grooves 17. Each mounting slot 12 is rotatably connected to a threaded rod 16. The threads on both sides of the center point of the horizontal axial section of the threaded rod 16 are in opposite directions. Each end of the threaded rod 16 is threadedly fitted with a moving block 6. The top of the moving block 6 is slidably connected to a sliding rod 3. A traction plate 5 is rotatably connected to the top of the moving block 6. A connecting block 2 is rotatably connected to the top of the traction plate 5. The connecting block 2 is fixedly connected to the bottom of the guide plate 10. The threaded rods 16 in the multiple mounting slots 12 are connected by a connecting... Rod 4 is fixedly connected. A motor 7 is fixedly connected to the outer wall of one end of plate 1. The output shaft of motor 7 is fixedly connected to a shaft 8. One end of shaft 8 is fixedly connected to one of the threaded rods 16. Specifically, the guide grooves on multiple guide plates guide the fluid. The shaft on the output shaft can be rotated by controlling the motor to start. At this time, the shaft drives one of its threaded rods to rotate. When the threaded rods rotate, the connecting rod causes the other threaded rods to rotate as well. Because the threads on both sides of the center point of the horizontal axis section of the threaded rod are set in opposite directions, the two moving blocks connected to the threaded rods move in opposite directions when the threaded rods rotate. At this time, the traction plate on the moving block will pull the guide plate down. See Figure 2 .

[0033] In this embodiment, as Figure 4 and Figure 5 As shown, the quick-installation structure includes an insert block 18 on the bottom of the guide plate 10, and an assembly groove 23 on the connecting block 2 corresponding to the insert block 18. The insert block 18 is slidably inserted into the assembly groove 23. Push rods 19 are slidably inserted into both ends of the connecting block 2. A locking block 20 is fixedly connected to one end of the push rod 19. The top of one end of the locking block 20 is inclined. A slot 24 corresponding to the locking block 20 is provided on the side wall of the insert block 18. A positioning sleeve 21 is fixedly sleeved on one end of the push rod 19. Springs 22 are fixedly connected between both ends of the positioning sleeve 21 and the connecting block 2. Specifically, the insert block on the bottom of the guide plate is pressed into the assembly groove on the connecting block. At this time, the two ends of the insert block abut against the inclined surface on the locking block. At the same time, the locking block will push the push rod 19 to move. The positioning sleeve stretches the springs on both ends. When the locking block and the slot are parallel, the spring rebound force causes the push rod to push the locking block back into the slot to realize the assembly between the guide plate and the connecting block, which makes it easy to replace the guide plate.

[0034] In this embodiment, both sides of the inner wall of the mounting groove 12 are provided with a connected receiving groove 14, and one side of the receiving groove 14 is provided with a connected slot 13. A limiting rod 15 is slidably inserted into the slot 13. One end of the limiting rod 15 is fixedly connected to the wedge block 9. Specifically, when the guide plate moves down, both ends will press against the wedge block, moving from the narrow side to the wide side of the wedge block. At the same time, under the pressure of the guide plate, the wedge block causes the limiting rod to slide in the slot and store the wedge block into the receiving groove. By using the wedge block as the top structure of the guide plate, and the tops of the two opposing wedge blocks as the openings of the guide groove, the opening diameter and depth of the guide structure are expanded.

[0035] In this embodiment, the wedge block 9 is designed with a wider top and a narrower bottom, which causes horizontal displacement under the pressure at both ends of the guide plate 10.

[0036] In this embodiment, a spring 11 is sleeved on the limiting rod 15. The two ends of the spring 11 are fixedly connected to the inner wall of the receiving groove 14 and the wedge block 9, respectively. The spring's rebound force can cause the wedge block to automatically return to its initial position when the guide plate 10 and the wedge block 9 are separated.

[0037] The working process of this embodiment is as follows: Under the drive of the motor 7, the shaft 8 on the output shaft rotates. At this time, the shaft 8 drives one of its threaded rods 16 to rotate. When the threaded rod 16 rotates, the connecting rod 4 causes the other threaded rods to rotate as well. Since the threads on both sides of the center point of the horizontal axis of the threaded rod 16 are set in opposite directions, when the threaded rod 16 rotates, the two moving blocks 6 threaded on it move in opposite directions, which makes the included angle between the two traction plates 5 larger, pulling the guide plate 10 down. When the guide plate 10 moves down, the two ends will move from the narrow side of the wedge block 9 to the wide side. Under the pressure of the guide plate 10, the wedge block 9 causes the limiting rod 15 to slide in the slot 13 and store the wedge block 9 into the receiving groove 14. The wedge block 9 serves as the top structure of the guide plate 10, and the tops of the two opposing wedge blocks 9 serve as the openings of the guide groove 17, thereby realizing the dynamic adjustment of the depth and opening diameter of the guide structure. The variations in the depth and opening diameter of the aforementioned flow guiding structures can alter the area and thickness of the low-velocity reflux zone on the surface of fluid equipment, reducing the direct impact of particles carried in the fluid on the equipment surface and achieving superior anti-wear performance. Simultaneously, it can also address the issue of excessively thick low-velocity regions reducing fluid velocity within the equipment, thereby improving its hydraulic performance.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
