[0002] Water conservancy and hydropower refer to the comprehensive field of using water resources for water conservancy project construction and hydropower generation. Water conservancy projects are mainly used to control, regulate and utilize surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits;
[0003] A fastening device is a mechanical device used to connect, fix and clamp objects. Its main function is to ensure the firm and reliable connection between different components and prevent loosening, separation or displacement under various external forces;
[0004] Some fastening devices can only be applied to components with specific specifications, shapes or sizes. For different types of water conservancy and hydropower construction objects, such as various pipelines, etc., and the fixed positions cannot be adjusted flexibly, so the versatility is poor and it cannot meet the diverse construction needs. In water conservancy and hydropower construction, due to factors such as the impact of water flow and the vibration of equipment, large instantaneous impacts will be generated. Since the fastening device lacks a buffer device, these impact forces will directly act on the fastening components, which may cause deformation and fracture of fasteners such as bolts and nuts. Therefore, a fastening device for water conservancy and hydropower construction is proposed to solve the above problems. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a fastening device for water conservancy and hydropower construction, including a fixed base 1 and an adjusting table 2. Fixing mechanisms are threadedly connected to the left and right sides of the top of the adjusting table 2, and the fixing mechanisms are used to fix the pipe.
[0031] The fixing mechanism includes an upper housing 3 and a lower housing 4. On both the left and right sides of the bottom of the lower housing 4, a first threaded column 12 is fixedly connected. The lower housing 4 is threadedly connected to the adjusting table 2 through the first threaded column 12. A second nut 10 is threadedly connected to the bottom of the first threaded column 12. On the left side of the top of the lower housing 4, a threaded lead screw 8 is threadedly connected. The bottom end of the threaded lead screw 8 is threadedly connected to a first nut 9. The top end of the threaded lead screw 8 is rotatably connected to the upper housing 3. At the central position inside the upper housing 3, an upper shock-absorbing tile 5 is fixedly connected. At the central position inside the lower housing 4, a shock-absorbing mechanism is provided, and the shock-absorbing mechanism is used to absorb the vibration generated by the pipeline.
[0032] The shock-absorbing mechanism includes a lower shock-absorbing tile 6. The bottom of the lower shock-absorbing tile 6 is fixedly connected to the central position of the bottom of the lower housing 4. On both sides of the left and right ends near the center inside the lower shock-absorbing tile 6, shock-absorbing springs 7 are fixedly connected. The pipeline is fixed between the upper shock-absorbing tile 5 and the lower shock-absorbing tile 6. When the pipeline generates vibration, the kinetic energy is absorbed by the shock-absorbing springs 7, thereby reducing the damage to the pipeline.
[0033] Refer to Figure 3 and Figure 4 , at the central position of the bottom end of the adjusting table 2, a second threaded column 13 is fixedly connected. The second threaded column 13 passes through the fixed base 1. The fixed base 1 and the adjusting table 2 are threadedly connected through a third nut 11 and the second threaded column 13. On the top of the right side of both the upper housing 3 and the lower housing 4, a fixing buckle 14 is fixedly connected. After the upper housing 3 and the lower housing 4 clamp the pipeline, they are threadedly connected through the fixing buckle 14. When in use, when adjusting the height of the pipeline to be fixed, that is, adjusting the relative height of the adjusting table 2 to the fixed base 1.
[0034] Working principle: In water conservancy and hydropower projects, when fixing the pipeline, the fixed base 1 is fixed on a fixed platform, such as a cement pier, through the countersunk threaded hole 15. After fixing, due to the overall length of the pipeline being too long, there will be a deviation in the height to be fixed. At this time, the horizontal height of the adjusting table 2 is adjusted by moving the height of the second threaded column 13. After adjustment, the third nuts 11 at both ends of the fixed base 1 are tightened. Subsequently, the upper shock-absorbing tile 5 is opened through the threaded lead screw 8, and the pipeline is placed between the upper shock-absorbing tile 5 and the shock-absorbing spring 7. Due to the width of the pipeline, after adjusting the height of the threaded lead screw 8, the first nut 9 is tightened. Subsequently, the upper housing 3 and the lower housing 4 are fastened through the fixing buckle 14. When the pipeline generates vibration due to water hammer effect, etc., the force generated by the vibration is transmitted through the lower shock-absorbing tile 6 and then absorbed by the shock-absorbing spring 7, reducing the damage to the pipeline.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
