Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy pipelines, and specifically relates to a water conservancy pipeline connecting device for water conservancy projects. Background Technique

[0002] A water conservancy project refers to physical facilities such as reservoirs, hydropower stations, dams, channels, sluice gates, and pumping stations built by human society to meet the needs of survival and development, prevent and control disasters such as floods, droughts, water pollution, and soil erosion, and meet the water needs of human life and industrial and agricultural production.

[0003] In water conservancy projects, the connection of pipelines is an essential facility. In the "A water conservancy pipeline connecting device for water conservancy projects" mentioned in the publication number "CN217153380U", it is pointed out that the connection structure of existing water conservancy water conveyance pipelines is relatively simple, and the strength it can bear is low. When the water pressure is too high, the connection of the water pipes will burst, resulting in the outflow of water sources and a large amount of waste. It mainly uses structures such as a bottom sealing pipe, an upper sealing pipe, and a sealing ring to connect water conservancy pipelines. However, during the actual installation of pipelines, the pipelines need to deal with problems such as thermal expansion, avoiding damage, and occupying space. Therefore, the layout of the pipelines is often curved, and the above method cannot connect the pipelines at the corners. Therefore, it needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the existing technology and provide a water conservancy pipeline connecting device for water conservancy projects.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water conservancy pipeline connecting device for water conservancy projects, including two groups of positioning pipe fittings, a corner pipeline, and two groups of vertical pipelines, further including:

[0006] An angle adjustment mechanism, which is arranged on the positioning pipe fitting and is used for connecting pipelines with different angles;

[0007] Among them, the angle adjustment mechanism includes a movable plate. The movable plate is hinged to the top of the positioning pipe fitting through a round shaft. A threaded rod passes through between the two movable plates. The threaded rod is fixed to one side of the movable plate. A nut is threadedly connected to the outer surface of the threaded rod. A sealing groove is provided on the inner wall of the positioning pipe fitting, and a sealing ring is inlaid on the inner wall of the positioning pipe fitting. Fixing plates are fixed at both ends of the positioning pipe fitting, and the two fixing plates are fixed by bolts.

[0008] In the above, the positioning pipe fitting includes an upper positioning pipe and a lower positioning pipe. Movable plates are fixed on the outer surfaces of the upper positioning pipe and the lower positioning pipe. Sealing grooves and sealing rings are provided on the inner walls of the upper positioning pipe and the lower positioning pipe, and fixing plates are fixed on both sides thereof.

[0009] As described above, when the bolt fixes the two groups of fixing plates, the upper positioning pipe and the lower positioning pipe can form a ring.

[0010] As described above, the upper positioning pipe and the lower positioning pipe are wrapped around the outer surfaces of the vertical pipe and the corner pipe. Sealant is bonded at the butt joint of the vertical pipe and the corner pipe. The sealing rings are located on both sides of the sealing groove and are in extrusion contact with the vertical pipe and the corner pipe.

[0011] As described above, the vertical pipes are located at both ends of the corner pipe, and the ends of the vertical pipes are in contact with the corner pipe. The contact part of the vertical pipe and the corner pipe bulges outwards and is embedded in the inner wall of the sealing groove and is adapted to the sealing groove.

[0012] As described above, there are two nuts arranged on the surface of each group of threaded rods. The two nuts are respectively located on both sides of a group of movable plates and clamp the movable plates.

[0013] Compared with the prior art, the water conservancy pipeline connection device for water conservancy projects has the following beneficial effects:

[0014] First, through the cooperation between the nut and the threaded rod, the present invention can fix the movable plate, thereby controlling the distance between the two groups of positioning pipe fittings. At the same time, through the cooperation between the movable plate and the round shaft, the rotation of the positioning pipe fittings can be controlled. Therefore, the included angle and distance between the two groups of positioning pipe fittings can be controlled, enabling them to be sleeved on the corner pipe and the vertical pipe. At the same time, through the cooperation between the fixing plate and the bolt, the corner pipe and the vertical pipe are fixed in the middle of the positioning pipe fittings, thereby facilitating the connection of vertical or corner pipes.

[0015] Second, the present invention bonds sealant between the corner pipe and the vertical pipe, and through the cooperation between the sealing groove and the corner pipe and the vertical pipe, the separation of the corner pipe and the vertical pipe is restricted. At the same time, the sealing rings distributed on both sides of the sealing groove seal both sides of the pipe connection, improving the sealing performance, and the distance between the two groups of movable plates is restricted by the nut, improving the stability of the pipe connection.

[0016] Other advantages, objectives, and features of the present invention will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-5 shown, the present utility model provides a water conservancy pipeline connection device for water conservancy projects, including two groups of positioning pipe fittings 1, a corner pipe 10 and two groups of vertical pipes 11, and further including:

[0025] An angle adjustment mechanism, which is arranged on the positioning pipe fitting 1 and is used for connecting pipes with different angles;

[0026] Among them, the angle adjustment mechanism includes a movable plate 3. The movable plate 3 is hinged to the top of the positioning pipe fitting 1 through a round shaft 2. A threaded rod 4 passes through between the two groups of movable plates 3. The threaded rod 4 is fixed to one side of the movable plate 3. A nut 5 is threadedly connected to the outer surface of the threaded rod 4. A sealing groove 6 is opened on the inner wall of the positioning pipe fitting 1. A sealing ring 7 is inlaid on the inner wall of the positioning pipe fitting 1. Fixing plates 8 are fixed at both ends of the positioning pipe fitting 1. The two groups of fixing plates 8 are fixed by bolts 9.

[0027] Through the cooperation between the threaded rod 4 and the movable plate 3, the movable plate 3 can move along the outer surface of the threaded rod 4. At the same time, through the cooperation between the nut 5 and the threaded rod 4, the movable plate 3 can be fixed, so that the distance between the two groups of positioning pipe fittings 1 can be controlled. At the same time, through the cooperation between the movable plate 3 and the circular shaft 2, the positioning pipe fitting 1 can be controlled to rotate, so the angle and distance between the two groups of positioning pipe fittings 1 can be controlled, so that they can be sleeved on the corner pipe 10 and the vertical pipe 11. At the same time, through the cooperation between the fixed plate 8 and the bolt 9, the corner pipe 10 and the vertical pipe 11 are fixed to the middle part of the positioning pipe fitting 1, and the assembly point of the corner pipe 10 and the vertical pipe 11 can be positioned through the sealing groove 6 and closed by the sealing ring 7, thereby ensuring its sealing and facilitating the connection of vertical or corner pipes.

[0028] like Figure 1 , 2 As shown, the positioning pipe fitting 1 includes an upper positioning tube 101 and a lower positioning tube 102, and movable plates 3 are fixed to the outer surfaces of the upper positioning tube 101 and the lower positioning tube 102, and sealing grooves 6 and sealing rings 7 are provided on the inner walls of the upper positioning tube 101 and the lower positioning tube 102, and fixed plates 8 are fixed on both sides thereof.

[0029] Through the design of the upper positioning tube 101 and the lower positioning tube 102, they can be respectively covered on the upper surface and the lower surface of the corner pipe 10 and the vertical pipe 11, and at the same time, the two sets of fixing plates 8 are fixed by bolts 9, so that the upper positioning tube 101 and the lower positioning tube 102 can be positioned, and then the corner pipe 10 and the vertical pipe 11 can be connected and sealed through the upper positioning tube 101 and the lower positioning tube 102.

[0030] like Figure 1 , 4 As shown, when the bolts 9 fix the two sets of fixing plates 8, the upper positioning tube 101 and the lower positioning tube 102 can form a circular ring.

[0031] Through the design of the bolts 9 , the upper positioning tube 101 and the lower positioning tube 102 can be fixed. At this time, the upper positioning tube 101 and the lower positioning tube 102 will form a ring, so that they can fit with the corner pipe 10 and the vertical pipe 11 .

[0032] like Figure 2 , 3 As shown in Figure 4, the upper positioning tube 101 and the lower positioning tube 102 are covered on the outer surfaces of the vertical pipe 11 and the corner pipe 10, and the joints of the vertical pipe 11 and the corner pipe 10 are bonded with sealant. The sealing ring 7 is located on both sides of the sealing groove 6 and is in extrusion contact with the vertical pipe 11 and the corner pipe 10.

[0033] Through the design of the sealing ring 7, since the sealing ring 7 is located on both sides of the sealing groove 6, and the sealing groove 6 is located at the docking part of the corner pipe 10 and the vertical pipe 11, the corner pipe 10 and the vertical pipe 11 can be sealed to prevent water from overflowing.

[0034] As Figure 2 , 3 shown, the vertical pipes 11 are located at both ends of the corner pipe 10, and the ends of the vertical pipes 11 are in contact with the corner pipe 10. The parts where the vertical pipes 11 and the corner pipe 10 are in contact bulge outwards, and the inner walls of the parts embedded in the sealing groove 6 are adapted to the sealing groove 6.

[0035] Through the design of the sealing groove 6, since the parts where the vertical pipe 11 and the corner pipe 10 are in contact bulge outwards, and the bulging parts of the vertical pipe 11 and the corner pipe 10 are embedded in the inner wall of the sealing groove 6, it can play a role in limiting the vertical pipe 11 and the corner pipe 10, and prevent gaps from appearing between the vertical pipe 11 and the corner pipe 10.

[0036] As Figure 5 shown, there are two sets of nuts 5 arranged on the surface of each group of threaded rods 4. The two sets of nuts 5 are respectively located on both sides of a group of movable plates 3 and clamp the movable plates 3.

[0037] Through the design of the nut 5, the movable plate 3 can be fixed, and the movement of the threaded rod 4 along the inner side of the movable plate 3 can be restricted. Thus, the two groups of movable plates 3 can be supported by the threaded rod 4, and the strength of the pipe connection can be improved.

[0038] Working principle:

[0039] First, through the cooperation between the threaded rod 4 and the movable plate 3, the movable plate 3 can move along the outer surface of the threaded rod 4. At the same time, through the cooperation between the nut 5 and the threaded rod 4, the movable plate 3 can be fixed. Thus, the distance between the two groups of upper positioning pipes 101 and the two groups of lower positioning pipes 102 can be controlled. At the same time, through the cooperation between the movable plate 3 and the round shaft 2, the rotation of the positioning pipe fitting 1 can be controlled. Therefore, the included angle and distance between the two groups of positioning pipe fittings 1 can be controlled. After that, the upper positioning pipe 101 and the lower positioning pipe 102 are sleeved on the corner pipe 10 and the vertical pipe 11, and through the cooperation between the fixing plate 8 and the bolt 9, the corner pipe 10 and the vertical pipe 11 are fixed between the upper positioning pipe 101 and the lower positioning pipe 102. At the same time, the assembly part of the corner pipe 10 and the vertical pipe 11 can be positioned through the sealing groove 6, and the connection between the pipes is completed.

[0040] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
