Description

Technical Field

[0001] This utility model relates to the field of hydropower engineering technology, and in particular to an underwater cable protection structure for hydropower engineering. Background Technology

[0002] Hydropower engineering, also known as water conservancy and hydropower engineering, refers to engineering technologies that utilize water resources. It mainly includes a series of engineering activities such as hydropower generation, farmland irrigation, urban water supply, river management, flood control and disaster reduction, water environment protection and ecological restoration.

[0003] According to the search results, a submarine cable protection component for preventing damage (publication number CN111697524B) includes a main body, a cleaning device movably installed inside the main body, and a guide block movably installed outside the cleaning device. Guide grooves are provided on both sides of the guide block. A reinforcing rotating rod is movably installed at the lower end of the main body. Because the guide blocks are continuously and equidistantly arranged outside the cleaning device, when the submarine current impacts the outside of the cleaning device, the force applied to the guide block is increased. This causes the cleaning device to rotate between the outside of the cable and the inside of the main body. Furthermore, the drive groove is annular and continuously curved in a wave-like shape. When the cleaning device rotates, the reinforcing rotating rod within the drive groove allows the cleaning device to move left and right along the trajectory of the drive groove while rotating, thus scraping off marine organisms attached to the outside of the cable. This achieves the effect of reducing the impact of submarine currents on the cable while simultaneously cleaning off attached organisms.

[0004] Based on the aforementioned patent, by effectively cleaning the external attached organisms, the maintenance cost of submarine cables is greatly reduced, and the cleaning device's rotation cleaning effect on marine organisms is further improved. It ensures that the submarine current can only contact and exert force on the guide block that moves onto the cleaning device, avoiding the submarine current from contacting the guide block at the lower end of the cleaning device and generating the opposite force. It also prevents the device body and cable from being pulled upwards and away from the cable's preset position when the submarine current impacts. However, the device is only fixed by the blades being inserted into the mud and sand at the bottom of the water. The fixing effect is not good enough. The cable and device are likely to move due to the influence of the water flow. Long-term use will also cause loosening and movement problems.

[0005] In response to this technical problem, this application proposes an underwater cable protection structure for hydropower projects. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an underwater cable protection structure for hydroelectric engineering. The base plate is fixed to the bottom of the water by a fixed column, and the fixed head inside the fixed column is moved outward by rotating the rotating plate, thereby improving the fixing effect between the fixed column and the bottom of the water, and thus improving the fixing effect of the entire device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An underwater cable protection structure for hydropower engineering includes a base plate, a support base fixedly connected to the top center of the base plate, a lower protective plate fixedly connected to the top of the support base, an upper protective plate disposed at the top of the lower protective plate, the outer walls of the lower protective plate being connected to the upper protective plate on both sides via connecting components, fixing posts disposed at the four corners of the inner wall of the base plate, a limit ring fixedly connected to the outer wall of the top of the fixing post, multiple fixing components disposed at the bottom inner wall of the fixing post to improve the fixing effect of the device, a driving component disposed on the inner wall of the fixing post to drive the fixing components to operate, and a buffer plate connected to the outer wall of the upper protective plate via multiple buffer components to reduce the impact on the device.

[0009] Furthermore, the connecting assembly includes lower connecting plates fixedly connected to both sides of the outer wall of the lower protective plate, and upper connecting plates fixedly connected to both sides of the outer wall of the upper protective plate. The lower connecting plates and the upper connecting plates are connected by bolts.

[0010] Furthermore, the fixing assembly includes a plurality of sliding rods slidably connected to the inner wall at the bottom end of the fixing column. Each sliding rod has a fixing head fixedly connected to its outer end and a top plate fixedly connected to its inner end. The top plate is connected to the inner wall of the fixing column by a first spring.

[0011] Furthermore, one end of the first spring is connected to the ejector plate, and the other end of the first spring is connected to the inner wall of the fixed column.

[0012] Furthermore, the driving assembly includes an extrusion cone located on the inner wall of the fixed column, with sliders fixedly connected to both ends of the extrusion cone. The outer walls of the sliders are slidably connected to the inner wall of the fixed column. A rotating plate is rotatably connected to the top of the limiting ring, and a screw is fixedly connected to the bottom of the rotating plate. The bottom of the screw is threadedly connected to the top of the extrusion cone.

[0013] Furthermore, one end of the inner side of the ejector plate corresponds to the bottom end of the extrusion cone.

[0014] Furthermore, the buffer assembly includes multiple connecting seats fixedly connected to the outer wall of the upper protective plate. A sliding ring is slidably connected to the inner wall of the connecting seat. A connecting rod is fixedly connected to one end of the outer side of the sliding ring.

[0015] Furthermore, one end of the second spring is connected to the sliding ring, and the other end of the second spring is connected to the inner wall of the connecting seat.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the base plate is fixed to the bottom of the water by a fixing column, and then the fixing head inside the fixing column is moved outward by rotating the rotating plate, which improves the fixing effect between the fixing column and the bottom of the water, thereby improving the fixing effect of the entire device.

[0018] 2. In this utility model, the friction of the cable can be reduced by the lower protective plate and the upper protective plate. When the buffer plate is impacted by a collision object, the collision object can be buffered by the cooperation of the sliding ring and the elastic force of the second spring, thereby reducing the impact on the cable and improving the cable's protection.

[0025] 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.

[0026] Reference Figures 1-3This utility model provides an embodiment of an underwater cable protection structure for hydropower engineering, comprising a base plate 1, a support base 2 fixedly connected to the top center of the base plate 1, a lower protective plate 3 fixedly connected to the top of the support base 2, an upper protective plate 7 provided at the top of the lower protective plate 3, lower connecting plates 4 fixedly connected to both sides of the outer wall of the lower protective plate 3, and upper connecting plates 6 fixedly connected to both sides of the outer wall of the upper protective plate 7. The lower connecting plates 4 and the upper connecting plates 6 are connected by bolts 5. Fixed posts 8 are provided at the four corners of the inner wall of the base plate 1. Limiting rings 9 are fixedly connected to the outer wall of the top of the fixed posts 8. Multiple sliding rods 10 are slidably connected to the inner wall of the bottom end of the fixed posts 8. A fixed head 11 is fixedly connected to one end of the outer side of each sliding rod 10. Each end is fixedly connected to an ejector plate 12. The ejector plate 12 is connected to the inner wall of the fixed column 8 by a first spring 13. One end of the first spring 13 is connected to the ejector plate 12, and the other end of the first spring 13 is connected to the inner wall of the fixed column 8 to improve the fixing effect of the device. An extrusion cone 14 is provided on the inner wall of the fixed column 8. Slider 15 is fixedly connected to both ends of the extrusion cone 14. The outer wall of the slider 15 is slidably connected to the inner wall of the fixed column 8. A rotating plate 17 is rotatably connected to the top of the limiting ring 9. A screw 16 is fixedly connected to the bottom of the rotating plate 17. The bottom of the screw 16 is threaded to the top of the extrusion cone 14. One end of the inner side of the ejector plate 12 corresponds to the bottom of the extrusion cone 14 to drive the fixed component to operate.

[0027] Specifically, the cable is placed inside the lower protective plate 3 and the upper protective plate 7, and the lower protective plate 3 and the upper protective plate 7 are fixed by the upper connecting plate 6 to protect the cable. Then, the fixing post 8 on the bottom plate 1 is fixed to the bottom of the water. By rotating the rotating plate 17, the screw 16 is rotated, which in turn drives the extrusion cone 14 to move downward, pushing out the ejector plate 12, which in turn drives the slide rod 10 to move outward, and then drives the fixing head 11 to move outward and lock it on the bottom of the water, which improves the fixing effect of the fixing post 8. Moreover, the elastic force of the first spring 13 can drive the fixing head 11 to reset when not in use.

[0028] Reference Figure 1 and Figure 4 Multiple connecting seats 18 are fixedly connected to the outer wall of the upper protective plate 7. A sliding ring 19 is slidably connected to the inner wall of the connecting seat 18. A connecting rod 20 is fixedly connected to one end of the outer side of the sliding ring 19. The sliding ring 19 is connected to the inner wall of the connecting seat 18 by a second spring 21. A buffer plate 22 is fixedly connected to one end of the outer side of the connecting rod 20. One end of the second spring 21 is connected to the sliding ring 19, and the other end of the second spring 21 is connected to the inner wall of the connecting seat 18 to reduce the impact on the device.

[0029] Specifically, when the outer wall of the buffer plate 22 is impacted, the impact is transmitted to the connecting seat 18 through the connecting rod 20. With the cooperation of the sliding ring 19 and the elastic force of the second spring 21, the impact can be buffered, reducing the impact force on the cable and improving the protection of the device.

[0030] Working Principle: First, the cable is placed between the lower protective plate 3 and the upper protective plate 7, and the two are firmly fixed together by the upper connecting plate 6 to protect the cable. Then, the fixing post 8 on the base plate 1 is anchored to the bottom of the water. By rotating the rotating plate 17, the screw 16 can be driven to rotate, which in turn causes the extrusion cone 14 to move downwards, pushing the ejector plate 12 outwards. This action, in turn, causes the sliding rod 10 to slide outwards, thereby pushing the fixing head 11 outwards and locking it to the bottom of the water, thus enhancing the stability of the fixing post 8. Furthermore, the elasticity of the first spring 13 ensures that the fixing head 11 can automatically reset when not in use. Secondly, when the outer wall of the buffer plate 22 is impacted, the impact force is transmitted to the inside of the connecting seat 18 through the connecting rod 20. Thanks to the synergistic effect of the sliding ring 19 and the second spring 21, the impact energy can be effectively absorbed, reducing the impact on the cable and thus improving the protective performance of the device.

[0031] 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.
