Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a support for pumped storage water transmission pipelines. Background Technology

[0002] Pumped-storage water pipelines are pipeline systems that utilize the mechanical energy of high-altitude energy storage and pumping stations to transport water from low-altitude areas to high-altitude areas. Such systems typically consist of at least two interconnected reservoirs, storing or releasing water energy through various elevation differences.

[0003] When installing pumped storage pipelines, support seats are needed to support and fix the pipeline, especially at corners, to reduce the impact and vibration caused by the water flow inside the pipeline. However, since the support seats are located at the bottom of the pipeline, and the pumped storage water transmission pipeline has a large diameter and is located inside a tunnel, it is difficult to support the existing pipeline. Therefore, integral support seats are troublesome to use and are greatly affected by the terrain. In order to improve the installation efficiency and load-bearing stability, it is necessary to design a support seat for pumped storage water transmission pipelines that is easy to install. Utility Model Content

[0004] The purpose of this utility model is to provide a support for pumped storage water pipelines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support base for pumped storage water pipelines, comprising:

[0006] A first support seat and a second support seat are provided. The first support seat is located in front of the second support seat. A set of grooves is provided on the opposite sides of the first and second support seats. A buffer liner is provided in the grooves.

[0020] 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.

[0021] Please see Figures 1-4A bearing seat for a pumped-storage water pipeline includes a first bearing seat 1 and a second bearing seat 11. The first bearing seat 1 is located in front of the second bearing seat 11. A set of grooves is formed on opposite sides of both the first and second bearing seats 11, and a buffer liner 12 is fixedly installed in each groove. Internally threaded pipes 111 are uniformly fixed on the front side of the second bearing seat 11. A first countersunk hole is formed through the front side of the first bearing seat 1, and a first cross bolt 14 is rotatably installed in the first countersunk hole. The internally threaded pipe 111 is inserted into the first countersunk hole, and the first cross bolt 14 is screwed into the internally threaded pipe 111. A first mounting groove is formed on the inner wall of the first countersunk hole, and a first spring 141 is fixedly installed in the first mounting groove. A first round-headed pin 142 is fixedly installed on the outer wall of the first spring 141. A first positioning hole is formed on the outer wall of the screw head of the first cross bolt 14. The round head of pin 142 is inserted into the first positioning hole. The internal threaded tube 111 is inserted into the first countersunk hole of the first bearing seat 1 and screwed into the first cross bolt 14 in the first countersunk hole. In this way, the second bearing seat 11 can be connected and fixed to the first bearing seat 1. When the first cross bolt 14 is tightened, the first positioning hole on the outside of the first cross bolt 14 is aligned with the first round head pin 142. At this time, the first spring 141 uses its own rebound force to drive the first round head pin 142 to insert into the first positioning hole and lock the first cross bolt 14. This prevents the vibration generated by the water flow in the water pipe 13 during pumping and energy storage from loosening the first cross bolt 14, thereby improving the reliability of the device. Support components are placed at the bottom of the first bearing seat 1 and the second bearing seat 11, and fixing components are placed on the outside of the first bearing seat 1 and the second bearing seat 11.

[0022] The support assembly includes a stud 17, a base 18 fixedly mounted on the bottom of the stud 17, a connecting ring 19 placed on the outer ring of the base 18, a second limiting ring 22 fixedly mounted on the inner side wall of the connecting ring 19, a first annular groove formed on the outer side wall of the base 18, the second limiting ring 22 rotatably disposed within the first annular groove, and a fixing lug 21 fixedly mounted on the outer side wall of the connecting ring 19. First threaded holes are evenly formed on the bottom of the first bearing seat 1 and the second bearing seat 11. The stud 17 is screwed into the first threaded hole. By rotating the stud 17, it can rotate up and down within the first threaded hole, thereby changing the position and height of the base 18. The multiple sets of bases 18 at the bottom of the first and second bearing seats 11 can be independently height-adjusted, so that the first bearing seat 1 and the second bearing seat 11 can be installed more stably on the rough ground. The connecting ring 19 can rotate on the outer ring of the base 18 through the second limiting ring 22, thereby driving the fixing ear 21 to rotate. By adjusting the position of the fixing ear 21, it can be better contacted with the ground. Then, after the expansion bolt is used to pass through the fixing ear 21 and connect it to the ground, the installation of the device is completed. The height-adjustable stud 17 and the position-adjustable fixing ear 21 can improve the stability of the device after installation on the rough ground.

[0023] The fixing assembly includes support plates 15. Each of the two sets of support plates 15 has a set of sliding grooves on opposite sides. Sliding plates 23 are slidably disposed within the sliding grooves. Anti-slip pads 2 are fixedly disposed on opposite sides of each of the two sets of sliding plates 23. Two sets of connecting holes are evenly distributed on the opposing sides of each of the two sets of sliding plates 23. A second annular groove is formed on the inner wall of each connecting hole. Two sets of threaded countersunk holes are evenly distributed on the opposing sides of the two sets of support plates 15. The threaded countersunk holes communicate with the sliding grooves, and second cross bolts 16 are screwed into the threaded countersunk holes. The outer ring of the stud of the second cross bolt 16 is fixedly provided with a first limiting ring 161. The stud portion of the second cross bolt 16 is located in the connecting hole. The first limiting ring 161 is rotatably disposed in the second annular groove. The inner side wall of the threaded countersunk hole is provided with a second mounting groove. The second spring 162 is fixedly disposed in the second mounting groove. The outer side wall of the second spring 162 is fixedly provided with a second round head pin 163. The outer side wall of the screw head of the second cross bolt 16 is provided with a second positioning hole. The round head portion of the second round head pin 163 is inserted into the second positioning hole. Two sets of support plates 15 are respectively fixed on the opposite sides of the first bearing seat 1 and the second bearing seat 11. The anti-slip pad 2 is tightly fitted to the outer side wall of the stud 17. By rotating the second cross bolt 16 counterclockwise, the anti-slip pad 2 of the sliding plate 23 is pulled into the groove through the first limiting ring 161, thereby separating the anti-slip pad 2 from the stud 17. After the height position of the stud 17 is determined, the second cross bolt 16 is rotated clockwise to push the sliding plate 23 closer to the stud 17 through the first limiting ring 161, thereby making the anti-slip pad 2 tightly fitted to the stud 17. The friction between the studs 17 fixes the studs 17. When the second cross bolt 16 is tightened, the second round head pin 163 aligns with the second positioning hole. The second spring 162 uses its own rebound force to drive the second round head pin 163 into the second positioning hole, thereby locking the second cross bolt 16. This prevents the vibration generated by the water flow in the water pipe 13 during pumping and energy storage from loosening the second cross bolt 16. The water pipe 13 is placed in the groove of the first bearing seat 1 and the second bearing seat 11. Two sets of buffer liners 12 are wrapped around the outer wall of the water pipe 13.

[0024] Working principle: Rotating the second cross bolt 16 counterclockwise pulls the anti-slip pad 2 of the sliding plate 23 into the groove through the first limiting ring 161, thereby separating the anti-slip pad 2 from the stud 17. The water supply pipe 13 is placed between the grooves of the first bearing seat 1 and the second bearing seat 11. The internally threaded pipe 111 is inserted into the first countersunk hole of the first bearing seat 1 and screwed into the first cross bolt 14 in the first countersunk hole. This allows the second bearing seat 11 to be docked and fixed to the first bearing seat 1. At this time, the buffer liner 12 in the groove will wrap around the water supply pipe 13. The buffer liner 12 can reduce the water flow in the water supply pipe 13 during pumping and energy storage. Vibration generated by the internal flow of water: When the first cross bolt 14 is tightened, the first positioning hole on the outer side of the first cross bolt 14 aligns with the first round head pin 142. At this time, the first spring 141 uses its own rebound force to drive the first round head pin 142 into the first positioning hole to lock the first cross bolt 14. This prevents the vibration generated by the water flow in the water pipe 13 during pumping and energy storage from loosening the first cross bolt 14, thereby improving the reliability of the device. By rotating the stud 17, it can be rotated up and down in the first threaded hole, thereby changing the position and height of the base 18. Due to the bottom of the first bearing seat 1 and the second bearing seat 11... Each of the multiple bases 18 can be independently height-adjusted, allowing the first support base 1 and the second support base 11 to be installed more stably on rough ground. The connecting ring 19 can rotate on the outer ring of the base 18 via the second limiting ring 22, thereby rotating the fixing ear 21. By adjusting the position of the fixing ear 21, it can be better aligned with the ground. After using expansion bolts to connect the fixing ear 21 to the ground, the installation of the device is completed. The height-adjustable stud 17 and the position-adjustable fixing ear 21 improve the stability of the device after installation on rough ground. After the position is determined, the second cross bolt 16 is rotated clockwise to push the sliding plate 23 closer to the stud 17 through the first limiting ring 161, so that the anti-slip pad 2 and the stud 17 are tightly fitted. The friction between the anti-slip pad 2 and the stud 17 fixes the stud 17. When the second cross bolt 16 is tightened, the second round head pin 163 is aligned with the second positioning hole. The second spring 162 uses its own rebound force to drive the second round head pin 163 to insert into the second positioning hole, thereby locking the second cross bolt 16. This prevents the vibration generated by the water flow in the water pipe 13 during pumping and energy storage from loosening the second cross bolt 16.
