[0029] Embodiment 1:
[0030] See also Figure 1-5 The utility model describes the above technical solution in detail through the following embodiments:
[0031] A power box for electric power engineering, comprising:
[0032] The power box 1 comprises a box body 11, a wire hole 15 is formed through the bottom of the box body 11, the wire hole 15 is used for wires and cables to enter the box body 11, a wire tube 2 is provided below the wire hole 15, and an adjustment component 3 is provided at the wire inlet of the wire tube 2.
[0033] The power box 1 is a metal box, which is made of metal plates by bending and welding. The wire holes 15 are circular holes, and there are two of them.
[0034] A mounting plate 14 is fixedly mounted in the box body 11 via isolation studs 13 , and the wire holes 15 are located between the mounting plate 14 and the back plate of the box body 11 .
[0035] The isolation stud 13 is threadedly connected to the box body 11 to separate a space between the mounting plate 14 and the back plate of the box body 11. The mounting plate 14 is fixedly connected to the isolation stud 13 by screws. After the wires and cables enter the box body 11 through the wire hole 15, they enter the back of the mounting plate 14.
[0036] A door 12 is rotatably mounted on the front side of the box body 11 via hinges.
[0037] The box door 12 is used to protect the equipment in the box body 11.
[0038] The wire passing pipe 2 includes a connecting pipe 21, which is welded and installed just below the wire passing hole 15. The connecting pipe 21 is connected to a bent pipe 23 through a vertical pipe 22, and the bent pipe 23 is connected to a fixed pipe 24. The fixed pipe 24 is connected to the adjustment component 3. The wire passing pipe 2 is used to protect the cables and prevent rainwater from entering.
[0039] The vertical pipe 22 is threadedly connected to the connecting pipe 21, and the curved pipe 23 is threadedly connected to the vertical pipe 22. The curved pipe 23 has a bending angle of 90°, which is used to change the direction of the wires and cables. At the same time, the bending increases the air flow resistance.
[0040] A clamping groove 25 is provided at the head of the fixing tube 24 .
[0041] The clamping groove 25 and the fixing pipe 24 are welded, and the fixing pipe 24 and the bent pipe 23 are threadedly connected. The outer diameter of the clamping groove 25 is greater than the outer diameter of the fixing pipe 24.
[0042] The adjustment component 3 includes a rotating tube 32 , which is rotatably connected to the fixed tube 24 via a locking ring 31 . A tube diameter adjustment component is provided between the inside of the rotating tube 32 and the fixed tube 24 , and is used to change the inner diameter of the rotating tube 32 .
[0043] The locking ring 31 is sleeved on the fixed tube 24 and wraps the outside of the clamping groove 25. The locking ring 31 can slide along the fixed tube 24. The axis of the rotating tube 32 coincides with the axis of the fixed tube 24.
[0044] The rotating tube 32 is threadedly connected to the locking ring 31 and abuts against the top surface of the clamping groove 25 . A plurality of guide grooves 33 are provided on the inner side of the rotating tube 32 .
[0045] When the locking ring 31 is tightened, the end surface of the rotating tube 32 abuts against the top surface of the slot 25, and the locking ring 31 abuts against the bottom surface of the slot 25, and the rotating tube 32 cannot rotate under the action of friction. When the locking ring 31 is loosened, the end surface of the rotating tube 32 is separated from the top surface of the slot 25, and the rotating tube 32 can rotate.
[0046] The pipe diameter adjustment assembly includes a fixed ring 34 and a sliding ring 35 . The fixed ring 34 is fixedly installed in the slot 25 . The sliding ring 35 is slidably connected to the guide slot 33 . A plurality of rotating ball slots 36 are provided on the opposite side of the fixed ring 34 and the sliding ring 35 .
[0047] The fixing ring 34 and the clamping groove 25 are in interference fit, and the inner diameter of the fixing ring 34 is the same as the inner diameter of the sliding ring 35 .
[0048] When the rotating tube 32 rotates, the sliding ring 35 can be driven to rotate, and the sliding ring 35 can slide along the guide groove 33 at the same time.
[0049] The two opposite rotating ball grooves 36 are connected by a ball head connecting rod 37 . Both ends of the ball head connecting rod 37 can rotate in the rotating ball groove 36 . A fireproof cloth 38 is arranged in the space surrounded by the ball head connecting rod 37 .
[0050] The fireproof cloth 38 is cylindrical, and the two ends of the fireproof cloth 38 are glued and fixed to the inner side surfaces of the fixed ring 34 and the sliding ring 35. When the sliding ring 35 rotates, it can drive one end of the ball head connecting rod 37 to rotate around the axis of the rotating tube 32. Since the other end of the ball head connecting rod 37 is rotatably connected to the rotating ball groove 36 of the fixed ring 34, and the fixed ring 34 cannot rotate, the ball head connecting rod 37 will tilt. As a result, the space surrounded by the ball head connecting rod 37 will become an hourglass shape, with inconvenient inner diameters at both ends and a smaller inner diameter in the middle.
[0051] At the same time, since the ball head connecting rod 37 is tilted, the vertical distance between the two ends of the ball head connecting rod 37 is shortened, so the sliding ring 35 will move along the guide groove 33 toward the fixed ring 34. The fireproof cloth 38 will twist and shrink along with the sliding ring 35.
[0052] When the wires and cables pass through the fixing ring 34 and the sliding ring 35 , they will be clamped by the ball head connecting rod 37 and the fireproof cloth 38 , thereby preventing external dust or animals from entering the box body 11 .
[0053] When the operator of this embodiment uses the equipment, he inserts the wires and cables from the opening of the rotating tube 32, passes through the fireproof cloth 38, enters the fixed tube 24, and then passes through the bent tube 23, the vertical tube 22 and the connecting tube 21 in sequence, and enters the box body 11 from the wire hole 15. At this time, the head of the wires and cables is located on the back of the mounting plate 14.
[0054] After the cable is inserted, the locking ring 31 is loosened to release the fixing of the rotating tube 32 .
[0055] A torque is applied to the rotating tube 32 to drive the rotating tube 32 to rotate.
[0056] When the rotating tube 32 rotates, the sliding ring 35 can be driven to rotate, and the sliding ring 35 can slide along the guide groove 33 at the same time.
[0057] When the sliding ring 35 rotates, it can drive one end of the ball head connecting rod 37 to rotate around the axis of the rotating tube 32. Since the other end of the ball head connecting rod 37 is rotatably connected to the rotating ball groove 36 of the fixed ring 34, and the fixed ring 34 cannot rotate, the ball head connecting rod 37 will tilt. As a result, the space surrounded by the ball head connecting rod 37 will become an hourglass shape, with the inner diameters of the two ends being inconvenient and the inner diameter in the middle becoming smaller.
[0058] At the same time, since the ball head connecting rod 37 is tilted, the vertical distance between the two ends of the ball head connecting rod 37 is shortened, so the sliding ring 35 will move along the guide groove 33 toward the fixed ring 34. The fireproof cloth 38 will twist and shrink along with the sliding ring 35.
[0059] The wires and cables passing through the fireproof cloth 38 are clamped by the fireproof cloth 38 and the ball head connecting rod 37. The wires and cables can be fixed and protected, and small animals or dust from the outside can be prevented from entering the box body 11.
[0060] After the fireproof cloth 38 and the ball head connecting rod 37 clamp the wires and cables, tighten the locking ring 31. The end surface of the rotating tube 32 abuts against the top surface of the slot 25, and the locking ring 31 abuts against the bottom surface of the slot 25. Under the action of friction, the rotating tube 32 cannot rotate. Therefore, the sliding ring 35 cannot move.
[0061] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
