Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a DC cable protection bracket. Background Art

[0002] DC cable is a conductor system used to transmit direct current power. Unlike AC cables, DC cables only transmit direct current signals with consistent voltage and current directions. DC cables can be used for long-distance power transmission and have lower power consumption during long-distance transmission. Therefore, they are suitable for high-voltage and long-distance transmission lines.

[0003] During the installation of DC cables, they are supported by mounting brackets. However, the brackets tightly ensure that the cables maintain the correct position and shape during installation and operation. The outer wall of the DC cable cannot be effectively protected. The DC cable will still be worn by pressure, extrusion, shear and other forces. Therefore, we propose a DC cable protection bracket to solve the existing problem. Utility Model Content

[0006] Preferably, the rear end of the support plate is connected to the installation frame, and the support rod and one end of the pressure rod are both provided with a towing rod, which is relatively distributed and has one end in a convex shape. The support plate is fixed to the outer wall of the installation frame, and the DC cable temporarily placed on the upper end of the support rod is limited by the towing rod to prevent the DC cable from detaching from the support rod due to the weight generated.

[0007] Preferably, the rear end of the installation frame is provided with symmetrically distributed brackets, and mounting holes are provided inside the brackets. The brackets are docked with the base and are plugged with the mounting parts through the mounting holes.

[0008] Preferably, the inner walls at both ends of the travel groove are provided with sliding grooves, and the slider is slidably installed inside the sliding groove and the travel groove. The slider slides inside the travel groove and the sliding groove, and obtains longitudinal sliding guidance inside the installation frame, and the travel plate connected thereto obtains sliding guidance.

[0009] Preferably, bearings are embedded and installed inside the upper end of the installation frame and the lower end of the travel groove, and the screw is rotatably inserted into the bearings. The screw rotates inside the installation frame through the bearings to obtain rotation support.

[0010] Preferably, the outer casings are relatively distributed and are semicircular in shape. The separated outer casings are sleeved on the outer side of the DC cable.

[0011] Preferably, one end of the spring is connected to the inner wall of the outer casing, and the outer casing is provided with through holes distributed at equal intervals. A guide rod with one end connected to the ferrule is provided inside the spring, and one end of the guide rod slides through the through hole, and an insulating pad is provided inside the ferrule. The ferrule is elastically supported inside the outer casing by the spring, and the guide rod limits the spring to prevent the spring from deflecting. The guide rod slides longitudinally inside the outer casing through the through hole during the squeezing process of the spring. The insulating pad not only plays an insulating role, but also plays a protective supporting role due to its own toughness.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model supports the cable on the support rod so that the DC cable maintains the correct position and shape during installation and operation, and the outer side of the DC cable is sleeved with an outer jacket to protect its outer wall, and the clamping sleeve in direct contact with the outer wall of the DC cable elastically supports it. When subjected to external force, the DC wire fence ring is buffered and protected by the clamping sleeve, and the universal tubes intermittently distributed on the outer jacket can adjust the bending of the outer jacket shell when the DC cable is bent at a large angle, thereby effectively protecting the DC cable during use.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, a DC cable protection bracket proposed by the utility model includes a mounting frame 1, a motor 2, a travel plate 4, an outer sleeve 9 and a ferrule 11. The front side of the mounting frame 1 is provided with a travel plate 4, and the front end of the travel plate 4 is provided with equidistantly distributed pressure rods 5. A support plate 6 is provided below the travel plate 4. The rear end of the support plate 6 is connected to the mounting frame 1. The front end of the support plate 6 is provided with equidistantly distributed support rods 7. The support rods 7 and one end of the pressure rod 5 are both provided with drag rods 8. The drag rods 8 are relatively distributed and one end is convex. The rear end of the mounting frame 1 is provided with symmetrically distributed brackets. 12, a mounting hole is provided inside the bracket 12, a motor 2 is provided at the upper end of the mounting frame 1, a screw 3 is provided at the output end of the motor 2, a travel groove 13 is provided inside the mounting frame 1, a slider 15 is provided at the rear end of the travel plate 4, slide grooves 14 are provided on the inner walls at both ends of the travel groove 13, the slider 15 is slidably installed in the slide groove 14 and the travel groove 13, bearings 16 are embedded and installed inside the upper end of the mounting frame 1 and the lower end of the travel groove 13, the screw 3 is rotatably inserted into the bearing 16, a screw hole is provided inside the slider 15, and the screw 3 is rotatably inserted into the screw hole.

[0021] Based on the implementation steps of Example 1: the DC cable is placed on the support rod 7, and the motor 2 drives the screw rod 3 to rotate. Because the slider 15 is guided, the thread inside the slider 15 is pushed to drive the travel plate 4 to descend, thereby driving multiple pressure rods 5 to press the DC cable at multiple positions. The pressed DC cable remains stable, and the installation frame 1 is installed with the base surface through the bracket 12 to support the DC cable during the laying process;

[0022] After the upper end of the DC cable is clamped, the cable is prevented from loosening, and it is suitable for clamping and fixing wire fences of various specifications, and is flexible to use.

[0023] like Figure 1-Figure 4As shown, compared with the first embodiment, a DC cable protection bracket proposed by the utility model further includes: a relatively distributed outer shell 9 is arranged between the support rod 7 and the pressure rod 5, the outer shell 9 is relatively distributed and is semicircular, and an intermittently distributed universal tube 10 is embedded and installed inside the outer shell 9, and equidistantly distributed clamping sleeves 11 are arranged inside the outer shell 9, and a spring 18 is arranged at the upper end of the clamping sleeve 11, one end of the spring 18 is connected to the inner wall of the outer shell 9, and equidistantly distributed through holes 17 are opened inside the outer shell 9, and a guide rod 19 with one end connected to the clamping sleeve 11 is arranged inside the spring 18, and one end of the guide rod 19 slides through the through hole 17, and an insulating pad 20 is arranged inside the clamping sleeve 11.

[0024] In this embodiment, when the DC cable is laid, the DC cable is placed inside the clamping sleeve 11, and the upper and lower ends of the DC cable are both sleeved inside the outer sleeve 9. The outer sleeve 9 is pressed and held by the pressure rod 5. When the wire fence needs to change direction at a bend, the universal tube 10 is moved to bend the outer sleeve 9 to adapt to the angle of the DC cable after bending, thereby achieving effective sleeve connection of the DC cable at the bend. When the impact force acts on the outer sleeve 9, the spring 18 is used to buffer and protect the DC cable. When the protection requirement of the DC cable needs to be strengthened, the wear on the DC cable is reduced by protecting the outside of the DC cable.
