Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for hydropower construction, specifically an auxiliary bending and guiding device for hydropower installation. Background Technology

[0002] During plumbing and electrical installations, conduits often need to be bent to adapt to different installation environments and wiring requirements. Traditional bending methods often rely on manual operation, which is not only inefficient but also makes it difficult to guarantee bending accuracy and consistency, while increasing labor intensity. Furthermore, manual bending can easily lead to damage or deformation of the conduits at the bends, affecting the normal operation and safety of the plumbing and electrical system. A search revealed Chinese Patent Publication No. CN119159787A, which discloses an auxiliary bending and guiding device for plumbing and electrical installations. This device includes a base plate, a traction arm fixed to the surface of the base plate, a swing arm rotatably connected to the surface of the base plate, connecting plates fixed to the ends of both the swing arm and the traction arm, a pad fixed to one end of the connecting plate, and a rubber plate fixed to the top surface of the pad.

[0003] While the above technical solutions can achieve precise control of the bending angle of the wiring conduit and improve bending accuracy and consistency, they require the rotation of multiple screws and nuts during use, making the operation cumbersome and increasing the workload. Furthermore, the wiring conduit is prone to some recovery due to internal stress after bending, and the above technical solutions cannot eliminate this stress, making them inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary bending and guiding device for hydropower installation, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an auxiliary bending guide device for water and electricity installation, including a base, an L-shaped base plate fixedly connected to the upper surface of the base, an adjustable limiting mechanism installed on the upper surface of the L-shaped base plate, a first electric heating rod fixedly installed at the center of the upper surface of the L-shaped base plate, a first protective sleeve sleeved on the outer surface of the first electric heating rod, and an adjustable bending guide mechanism installed through the outer surface of the L-shaped base plate;

[0006] The adjustable bending guide mechanism includes a connecting rod rotatably connected to the center of the lower surface of the L-shaped base plate. One end of the connecting rod is fixedly connected to a vertical rod. The upper surface of the L-shaped base plate is provided with an arc-shaped groove that matches the vertical rod. A rectangular block is fixedly connected to the top of the vertical rod. A horizontal rod is slidably connected to the outside of the rectangular block. One end of the horizontal rod is fixedly connected to a second electric heating rod. A second protective sleeve is rotatably sleeved on the outer surface of the second electric heating rod.

[0007] Preferably, a positioning rod is fixedly connected to the top of the rectangular block, and a locking nut is threaded onto the outer surface of the positioning rod to facilitate locking the position of the crossbar.

[0008] Preferably, the crossbar has a T-slot inside that mates with the rectangular block and the positioning rod, facilitating adjustment of the crossbar.

[0009] Preferably, the adjustable limiting mechanism includes a limiting plate slidably connected to the upper surface of the L-shaped base plate, a slider fixedly connected to the bottom end of the limiting plate, and an elongated groove that cooperates with the slider on the top of the L-shaped base plate to facilitate limiting one end of the wiring conduit.

[0010] Preferably, the inside of the long groove is rotatably connected to a lead screw that is threadedly connected to the inside of the slider, and one end of the lead screw is fixedly connected to a turntable to facilitate adjustment of the position of the limiting plate.

[0011] Preferably, a controller is fixedly installed on one side of the upper surface of the L-shaped base plate to facilitate the control of the opening and closing of the first electric heating rod and the second electric heating rod.

[0012] This utility model provides an auxiliary bending guide device for hydropower installation. It has the following beneficial effects:

[0013] This auxiliary bending guide device for water and electricity installation, through its adjustable limiting mechanism, first electric heating rod, and adjustable bending guide mechanism, can not only quickly guide and bend wiring pipes of different diameters, but also simplify operation and reduce workload. Furthermore, it can heat the wiring pipe during bending, which can change the stress distribution at the bend, making it less likely to revert to its original state after removal, thereby improving the bending effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example 1:

[0022] like Figure 1 and Figure 3 As shown, an auxiliary bending guide device for hydroelectric installation includes a base 1. An L-shaped base plate 2 is fixedly connected to the upper surface of the base 1. An adjustable limiting mechanism 3 is installed on the upper surface of the L-shaped base plate 2. The adjustable limiting mechanism 3 includes a limiting plate 31 slidably connected to the upper surface of the L-shaped base plate 2. A slider 32 is fixedly connected to the bottom end of the limiting plate 31. A long groove that mates with the slider 32 is opened on the top of the L-shaped base plate 2. A lead screw 33, which is threadedly connected to the inside of the slider 32, is rotatably connected through the long groove. A turntable 34 is fixedly connected to one end of the lead screw 33. In use, the turntable 34 is rotated according to the diameter of the wiring conduit. The rotation of the turntable 34 drives the lead screw 33 to rotate, which in turn drives the slider 32 and the limiting plate 31 to move through the thread, facilitating the limiting of one end of wiring conduits of different diameters.

[0023] Example 2:

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a first electric heating rod 4 is fixedly installed at the center of the upper surface of the L-shaped base plate 2. A first protective sleeve 5 is fitted onto the outer surface of the first electric heating rod 4. An adjustable bending guide mechanism 6 is installed through the outer surface of the L-shaped base plate 2. The adjustable bending guide mechanism 6 includes a connecting rod 61 rotatably connected to the center of the lower surface of the L-shaped base plate 2. A vertical rod 62 is fixedly connected to one end of the connecting rod 61. An arc-shaped groove 63 that mates with the vertical rod 62 is opened on the upper surface of the L-shaped base plate 2. A rectangular block 64 is fixedly connected to the top of the vertical rod 62. A horizontal rod 65 is slidably connected to the outside of the rectangular block 64. A second electric heating rod 66 is fixedly connected to one end of the horizontal rod 65. A second protective sleeve 67 is rotatably fitted onto the outer surface of the second electric heating rod 66. A positioning rod 68 is fixedly connected to the top of the rectangular block 64. A locking nut 69 is threaded onto the outer surface of the positioning rod 68. A T-shaped groove that mates with the rectangular block 64 and the positioning rod 68 is opened inside the horizontal rod 65. A controller is fixedly installed on one side of the upper surface of the L-shaped base plate 2.

[0025] Adjust the positions of the crossbar 65, the second electric heating rod 66, and the second protective sleeve 67 according to the diameter of the wiring conduit, so that one side of the second protective sleeve 67 abuts against the outer wall of the wiring conduit. Then, lock the crossbar 65 with the locking nut 69. Insert the external bending spring into the wiring conduit to prevent it from collapsing during bending. Then, activate the first electric heating rod 4 and the second electric heating rod 66 through the controller to collect heat on both sides of the wiring conduit. Rotating the crossbar 65 will drive the second protective sleeve 67 to rotate and guide the bending of the wiring conduit. After bending is completed, turn off the first electric heating rod 4 and the second electric heating rod 66. Because the wiring conduit is heated during bending, the stress distribution inside it can be changed, making it less likely to recover after bending and removal, thereby improving the bending effect.

[0026] Working principle: During use, the turntable 34 is rotated according to the diameter of the wiring conduit. The rotation of the turntable 34 drives the lead screw 33 to rotate, which in turn drives the slider 32 and the limiting plate 31 to move through the thread, making it convenient to limit one end of wiring conduits of different diameters. The positions of the crossbar 65, the second electric heating rod 66 and the second protective sleeve 67 are adjusted according to the diameter of the wiring conduit, so that one side of the second protective sleeve 67 abuts against the outer wall of the wiring conduit. Then, the crossbar 65 is locked by locking the locking nut 69. The external bending spring is inserted into the inside of the wiring conduit to prevent it from being crushed during bending. Then, the controller starts the first electric heating rod 4 and the second electric heating rod 66 to collect heat on both sides of the wiring conduit. Rotating the crossbar 65 will drive the second protective sleeve 67 to rotate and guide the bending of the wiring conduit. After bending is completed, the first electric heating rod 4 and the second electric heating rod 66 are turned off. Because the wiring conduit is heated during bending, the stress distribution inside it can be changed, making it less likely to recover after bending and removal, thereby improving the bending effect.
