Description

Technical Field

[0001] The present application relates to the technical field of electric power engineering, and in particular to an electric power engineering cable joint protection component. Background Art

[0002] The reason why the cable joints of power engineering need to be protected is that the main cable joints are usually outdoors or in harsh environments, and are easily eroded and damaged by natural factors such as sunlight, rain, wind and sand, which can easily cause oxidation, leakage and short circuit, thus affecting their normal operation and service life. The existing cable joints are generally protected by wrapping the joints with multiple layers of insulating tape, or by putting a soft rubber sleeve on the cable joint, and then using high temperature to shrink the soft rubber sleeve to fix it at the cable joint;

[0003] With respect to the above-mentioned related technologies, the inventor believes that, although the existing soft rubber sleeve or insulating tape can play a corresponding protective role on the cable joint, if the cable joint has a short circuit or other phenomena, it needs to be disassembled to inspect and repair the cable joint, which is relatively inconvenient and affects the actual work efficiency. Moreover, the insulating tape and soft rubber sleeve may not be convenient to be reused after being disassembled, which correspondingly increases the actual use cost;

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

[0020] By adopting the above technical scheme, firstly, two groups of cables to be connected can be inserted into the protective tube 1 through the elastic hose 2. At this time, by rotating the first knob 5, the corresponding protective part can be driven to fix and protect the cable joint. At the same time, by rotating the second knob 8, the first screw 7 connected to the elastic steel ring 6 can be driven to rotate, so that the connection of the elastic steel ring 6 shrinks and closes, which can correspondingly drive the elastic hose 2 to shrink, so that the inner wall can fit closely to the surface of the cable to prevent dust and water from entering the cable joint of the protective tube 1. The sealing cover 3 can be opened by pulling the handle 4, and then the first knob 5 can be rotated in the opposite direction to loosen the cable joint of the cable, so as to facilitate and quickly repair the cable joint. At the same time, the waterproof sealing gasket 15 can be used to seal and protect the sealing cover 3 and the protective tube 1 to prevent water or dust from entering the cable joint of the protective tube 1. The connection between the first knob 5 and the protective tube 1 is also provided with a waterproof sealing gasket, which can also play a good sealing and waterproof role.

[0021] Reference Figure 1 and Figure 3 The protective member includes a second screw 9, a threaded sleeve 10, a limiting rod 11, a sliding block 12, a fixing plate 13 and a protective pad 14. The end of the first knob 5 close to the protective tube 1 is fixedly connected to the second screw 9, and the end of the second screw 9 away from the first knob 5 is rotatably connected to the inner cavity side wall of the protective tube 1 through a rotating shaft. The surface of the second screw 9 is threadedly connected with two groups of threaded sleeves 10, one side of the two groups of threaded sleeves 10 is fixedly connected with a fixing plate 13 by bolts, and the inner cavity side walls of the two groups of fixing plates 13 are fixedly connected with a protective pad 14. The two groups of fixing plates 13 are fixedly connected with the sliding block 12 on one side away from the threaded sleeve 10 by bolts. The inner cavity side walls of the two groups of sliding blocks 12 are slidably connected to the limiting rod 11, and both ends of the limiting rod 11 are fixedly connected to the inner cavity side walls of the protective tube 1 by bolts;

[0022] By adopting the above technical solution, when the first knob 5 is rotated, the second screw rod 9 can be driven to rotate, and the fixing plate 13 can be limited by the limiting rod 11 and the two groups of sliding blocks 12 on its surface. Since the second screw rod 9 has two groups of opposite thread patterns on its surface, the two groups of threaded sleeves 10 on its surface can be driven to move inward or outward at the same time, thereby driving the two groups of fixing plates 13 and protective pads 14 to move, and the cable joints are protected and fixed. The two groups of protective pads 14 are both made of good insulating materials. When the cable joints need to be repaired and inspected, the first knob 5 can be rotated in the opposite direction to separate the two groups of fixing plates 13 and loosen the cable joints.

[0023] The implementation principle of an electric power engineering cable joint protection component in the embodiment of the present application is as follows: first, two groups of cables to be connected can be inserted into the protection tube 1 through the elastic hose 2. At this time, the first knob 5 can be rotated to drive the second screw rod 9 to rotate. The fixing plate 13 can be limited by the limiting rod 11 and the two groups of sliding blocks 12 on its surface. Since the second screw rod 9 has two groups of opposite thread patterns on its surface, the two groups of threaded sleeves 10 on its surface can be driven to move inward or outward at the same time, thereby driving the two groups of fixing plates 13 and the protection pads 14 to move, and the cable joints can be protected and fixed. Both groups of protection pads 14 are made of good insulating materials. At the same time, the first screw rod 7 connected to the elastic steel ring 6 can be driven to rotate by rotating the second knob 8, so that the connection of the elastic steel ring 6 shrinks and moves closer, which can drive the elastic hose 2 to shrink, so that its inner wall can fit closely to the surface of the cable to prevent dust and water from entering the cable joint of the protection tube 1, and when it is necessary When repairing and inspecting the cable joint, the first knob 5 can be rotated in the opposite direction to separate the two sets of fixing plates 13 and loosen the cable joint. The sealing cover 3 can be opened by pulling the handle 4, so that the cable joint can be repaired and inspected conveniently and quickly. At the same time, the waterproof sealing gasket 15 can be used to seal the sealing cover 3 and the protective tube 1 to prevent water or dust from entering the cable joint of the protective tube 1. The connection between the first knob 5 and the protective tube 1 is also provided with a waterproof sealing gasket, which can also play a good sealing and waterproof role. The overall operation is simple and easy to use. It can not only protect the cable joint to prevent dust or water from entering the cable joint, but also protect and fix the joint to prevent loosening, etc., and it is convenient to repair and inspect the cable joint at any time, which can not only effectively improve its actual work efficiency, but also its overall protection component can be used repeatedly, which can also effectively reduce its actual use cost accordingly.
