Description

Technical Field

[0001] This utility model relates to the field of hydraulic tunnel technology, specifically a steel lining reinforcement device for hydraulic tunnels. Background Technology

[0002] Hydraulic tunnels are water passageways excavated in mountains or underground. They can be used for irrigation, power generation, water supply, drainage, water conveyance, construction diversion, and navigation. Because hydraulic tunnels are subject to water erosion over long periods of time, reinforcement devices are installed inside them to extend their service life.

[0003] The existing Chinese patent with publication number CN220888568U discloses a steel-lined reinforced hydraulic tunnel. The hydraulic tunnel pipe has a water flow channel in the middle, and a stainless steel lining is provided on the inner side of the water flow channel. Four reinforcing plates are equidistantly arranged on the upper, lower, left, and right sides of the stainless steel lining. A fixing anchor is welded to the middle of the reinforcing plate. Water-proof grooves are provided on the inner side walls of the stainless steel lining at the reinforcing plates. Four fixing bolts are threaded at the four corners of the inner top wall of the stainless steel lining at the water-proof groove. A limit groove is fixedly provided on the left side of the stainless steel lining at the water-proof groove.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device supports the hydraulic tunnel through a stainless steel lining, but the stainless steel lining has a fixed size and cannot be used in hydraulic tunnels of various diameters, so it needs to be improved; therefore, in order to solve the above problems, a steel lining reinforcement device for hydraulic tunnels is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the above-mentioned technical problems, this utility model proposes a steel lining reinforcement device for hydraulic tunnels.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The hydraulic tunnel steel lining reinforcement device of this utility model includes a hydraulic tunnel body, and a support ring body is provided inside the hydraulic tunnel body. The support ring body includes a ring body one and a ring body two. A reinforcement component is installed on the surface of the support ring body. The reinforcement component includes a plurality of rotating brackets arranged in a ring and a plurality of threaded telescopic rods. The rotating bracket includes a connecting layer located in the middle. The two ends of the connecting layer are respectively rotatably connected to the rotating layer through a shaft. The other end of the rotating layer is rotatably connected to the outer wall of the support ring body. One end of the threaded telescopic rod is fixedly connected to the inner wall of the ring body two, and the other end of the threaded telescopic rod is rotatably connected to the inner wall of the ring body one.

[0007] Preferably, a gear one is fixedly connected to the other end of the threaded telescopic rod, and a gear two is meshed with the outer side of the gear one, with the side wall of the gear two being rotatably connected to the outer wall of the ring body one.

[0008] Preferably, the reinforcing component further includes a plurality of reinforcing holes, which are formed on the surface of the support ring.

[0009] Preferably, a fixing sleeve is fixedly connected to the inner side of the reinforcing hole, and an anchor rod is provided inside the fixing sleeve and the reinforcing hole.

[0010] Preferably, one end of the anchor rod is rotatably connected to a connecting ring, the surface of the connecting ring is provided with a plurality of connecting holes one, and the surface of the fixing sleeve is provided with a plurality of connecting holes two.

[0011] Preferably, bolts are inserted into the interior of the first and second connecting holes, and nuts are threaded onto the outer wall of the bolts.

[0013] Preferably, the support ring and the reinforcing assembly are made entirely of stainless steel.

[0014] The advantages of this utility model are:

[0015] 1. This utility model reduces the distance between ring one and ring two by rotating one end of the threaded telescopic rod. When the distance between ring one and ring two is reduced, the rotating bracket folds outward and unfolds to support and reinforce the inner wall of the hydraulic tunnel body at multiple points, thus preventing the overall collapse caused by internal erosion of the hydraulic tunnel body during long-term use. By adjusting the unfolding range of the rotating bracket, it can be applied to the reinforcement of hydraulic tunnel bodies of various sizes.

[0016] 2. This utility model uses a threaded telescopic rod to connect ring one and ring two. By rotating gear two, multiple sets of gear one are driven to rotate. The rotation of gear one drives the threaded telescopic rod to extend and retract, thereby facilitating quick adjustment of the distance between ring one and ring two and improving the convenience of use.

[0024] 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 scope of protection of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4 As shown, a steel lining reinforcement device for a hydraulic tunnel includes a hydraulic tunnel body 1. A support ring 2 is disposed inside the hydraulic tunnel body 1. The support ring 2 includes a first ring 21 and a second ring 22. A reinforcement component 3 is installed on the surface of the support ring 2. The reinforcement component 3 includes several rotating supports 31 arranged in a ring and several threaded telescopic rods 32. The rotating supports 31 include a connecting layer 311 located in the middle. The two ends of the connecting layer 311 are rotatably connected to rotating layers 312 via shafts. The other end of the rotating layer 312 is rotatably connected to the outer wall of the support ring 2. One end of the threaded telescopic rod 32 is fixedly connected to the inner wall of the second ring 22, and the other end is rotatably connected to the inner wall of the first ring 21. The threaded telescopic rod 32 includes a threaded cylinder end and a threaded rod end, which are threadedly connected. One end of the threaded telescopic rod 32 is the threaded cylinder end, and the other end is the threaded rod end.

[0027] Specifically, the threaded telescopic rod 32 is used to connect ring 5 body one and ring body two 22. In use, the supporting ring body 2 is placed inside the hydraulic tunnel body 1, and then one end of the threaded telescopic rod 32 is rotated to reduce the distance between ring body one 21 and ring body two 22. When the distance between ring body one 21 and ring body two 22 is reduced, the rotating bracket 31 folds outward and unfolds to abut against the inner wall of the hydraulic tunnel body 1 for multi-point support and reinforcement, so as to avoid the overall collapse caused by the internal erosion of the hydraulic tunnel body during long-term use. By adjusting the unfolding range of the rotating bracket 31, it can be used to reinforce hydraulic tunnel bodies 1 of various sizes.

[0028] The reinforcement component 3 also includes several reinforcement holes 36, which are formed on the surface of the support ring 2. A fixing sleeve 37 is fixedly connected to the inside of the reinforcement hole 36, and an anchor rod 4 is provided inside the fixing sleeve 37 and the reinforcement hole 36.

[0029] Specifically, the anchor rod 4 is inserted into the main body 1 of the hydraulic tunnel through the fixing sleeve 37 and the reinforcement hole 36 to fix the support ring 2 and prevent it from falling off.

[0030] One end of the anchor rod 4 is rotatably connected to a connecting ring 5. The surface of the connecting ring 5 is provided with several connecting holes 6. The surface of the fixing sleeve 37 is provided with several connecting holes 7. Bolts 8 are inserted into the connecting holes 6 and 7. Nuts 9 are threadedly connected to the outer wall of the bolts 8.

[0031] Specifically, the connecting ring 5 can rotate to facilitate the alignment of the first connecting hole 6 with the second connecting hole 7. An anchor rod 4 of appropriate length is selected according to the distance between the main body 1 of the hydraulic tunnel and the supporting ring body 2, so that when the anchor rod 4 is inserted into the main body 1 of the hydraulic tunnel, the connecting ring 5 completely fits the fixing sleeve 37. Then, the bolt 8 is passed through the first connecting hole 6 and the second connecting hole 7 and connected to the nut 9, thereby connecting the anchor rod 4 to the supporting ring body 2 and improving the support strength.

[0032] A support layer 313 is fixedly connected to the outer wall of the connecting layer 311, and a rubber layer is fixedly connected to the outer wall of the support layer 313.

[0033] Specifically, when the rotating bracket 31 rotates, the support layer 313 abuts against the inner wall of the hydraulic tunnel body 1, and the rubber layer increases the friction with the inner wall of the hydraulic tunnel body 1.

[0034] The support ring 2 and the reinforcing component 3 are made entirely of stainless steel.

[0035] Example 2

[0036] For comparison with Example 1, please refer to Figure 5As shown, this utility model provides another embodiment, in which the other end of the threaded telescopic rod 32 is fixedly connected to a gear 33, and the outer side of the gear 33 is meshed with a gear 34, and the side wall of the gear 34 is rotatably connected to the outer wall of the ring 21.

[0037] When adjusting the distance between ring 1 21 and ring 22, rotating gear 2 34 drives multiple sets of gear 1 33 to rotate. The rotation of gear 1 33 drives the threaded telescopic rod 32 to extend and retract, thus facilitating quick adjustment of the distance between ring 1 21 and ring 22.

[0038] Working principle: During use, the support ring 2 is placed inside the main body 1 of the hydraulic tunnel. Then, one end of the threaded telescopic rod 32 is rotated to reduce the distance between the first ring 21 and the second ring 22. When the distance between the first ring 21 and the second ring 22 is reduced, the rotating bracket 31 folds outward and unfolds to abut against the inner wall of the main body 1 of the hydraulic tunnel for multi-point support and reinforcement. This prevents the main body of the hydraulic tunnel from collapsing due to internal erosion during long-term use. By adjusting the unfolding range of the rotating bracket 31, it can be used to reinforce the main body 1 of hydraulic tunnels of various sizes.

[0039] By inserting the anchor rod 4 through the fixing sleeve 37 and the reinforcement hole 36 into the main body 1 of the hydraulic tunnel, and then connecting the bolt 8 through the connecting hole 1 6 and the connecting hole 2 7 to the nut 9, the anchor rod 4 is connected to the support ring 2, thereby fixing the support ring 2 to prevent it from falling off.
