[0002] Power cables are devices used to transport high-voltage electricity. When using power cables, high-voltage electricity can be transported effectively. The main function of power cables is to transmit and distribute electrical energy to ensure the normal operation of the power system. They are used in urban and rural power systems to connect power plants, substations, and to transport high-voltage power from power plants to substations, and then distribute the electricity to households, businesses, and industrial users through low-voltage cables.

[0003] The inventor discovered in his daily work that power cables still have at least the following problems: When using power cables, high-voltage electricity can be transported very well. The main function of power cables is to transmit and distribute electrical energy to ensure the normal operation of the power system. They are used in urban and rural power systems to connect power plants, substations, and to transport high-voltage power from power plants to substations, and then distribute the electricity to households, businesses, and industrial users through low-voltage cables. However, in actual use, because the surface of the cable is equipped with a rubber sheath, the cable needs to be wrapped around the surface of the collecting roller during transportation to avoid bending. This requires the collecting roller to collect the cable, which is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bend-resistant power cable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bending-resistant power cable, comprising a cable body, a protective device provided on the surface of the cable body, a limiting device provided at one end of the cable body, the protective device comprising a steel wire, and a locking groove provided on the surface of the cable body, the steel wire being disposed inside the locking groove.

[0006] The effect achieved by the above components is that when using the protective device, the steel wires are manually squeezed into the slots, which can strengthen the surface of the cable body to a certain extent, thus preventing the cable body from bending.

[0007] Preferably, the surface of the steel wire is uniformly provided with grooves, the inner wall of the groove is provided with a rubber ring, the surface of the rubber ring is fixedly connected with a fixing sleeve, and the fixing sleeve is sleeved on the surface of the cable body.

[0008] The effect achieved by the above components is that the rubber ring is manually placed on the inner wall of the groove, and then the fixing sleeve is placed on the surface of the cable body, which makes it easier to confine the steel wire inside the locking groove.

[0009] Preferably, the surface of the cable body is uniformly provided with fixing grooves, the inner wall of the fixing groove is provided with a rubber block, and the end of the rubber block away from the fixing groove is fixedly connected to the inner wall of the fixing sleeve.

[0010] The effect achieved by the above components is to squeeze the rubber block inside the fixing groove, which can effectively restrict the fixing sleeve to the surface of the cable body.

[0011] Preferably, the inner wall of the groove is provided with a positioning groove, the inner wall of the positioning groove is provided with a rubber rod, the bottom of the rubber rod is fixedly connected with a rubber ball, and the rubber ball is located at the bottom of the inner wall of the positioning groove.

[0012] The effect achieved by the above components is to squeeze the rubber rod into the inside of the positioning groove and squeeze the rubber ball to the bottom of the inner wall of the positioning groove, which can effectively prevent the steel wire from sliding on the inner wall of the positioning groove.

[0014] The effect achieved by the above components is as follows: when using the limiting device, the two fixing rings are respectively fitted onto the surfaces of the two ends of the cable body that are close to each other, and then the connecting strip is controlled to slide on the inner wall of the connecting groove. This makes it easy to restrict the two ends of the two cable bodies together, which makes it easy to connect the two ends of the two cable bodies together later.

[0015] Preferably, a rubber ring is fixedly connected to the inner wall of the fixing ring, and the surface of the rubber ring is uniformly provided with notches.

[0016] The effect achieved by the above components is that when the retaining ring is fitted onto the surface of the cable body, the rubber ring is well squeezed against the surface of the cable body, which can effectively restrict the retaining ring to the surface of the cable body. The notch allows the rubber ring to deform to a greater extent.

[0017] Preferably, a bolt is rotatably inserted into one side of the connecting strip, and the bolt thread is inserted into the side of the fixing ring away from the connecting strip.

[0018] The effect achieved by the above components is to allow manual control of bolt rotation, which facilitates control of the connecting strip sliding on the inner wall of the connecting groove.

[0019] Preferably, a damping rod is fixedly connected to the inner wall of the two fixed rings, and a spring is sleeved on the surface of the damping rod. The two ends of the spring are fixedly connected to the two opposite sides of the two fixed rings, respectively.

[0027] Example 1, as Figure 1-4 As shown, a bending-resistant power cable has a protective device 2 on the surface of the cable body 1 and a limit device 3 at one end of the cable body 1. When using power cables, high-voltage power can be transported effectively. The main function of power cables is to transmit and distribute electrical energy to ensure the normal operation of the power system. They are used in urban and rural power systems to connect power plants, substations, and to transport high-voltage power from power plants to substations, and then distribute the power to households, businesses, and industrial users through low-voltage cables.

[0028] Reference Figure 2 and Figure 3 The protective device 2 includes a steel wire 202. The surface of the cable body 1 is provided with locking grooves 201. The steel wire 202 is placed inside the locking grooves 201. When using the protective device 2, the steel wire 202 is manually pressed into the locking grooves 201, thereby strengthening the surface of the cable body 1 to a certain extent and preventing the cable body 1 from bending. The surface of the steel wire 202 is uniformly provided with grooves 203. A rubber ring 205 is provided on the inner wall of the groove 203. A fixing sleeve 206 is fixedly connected to the surface of the rubber ring 205. The fixing sleeve 206 is fitted onto the surface of the cable body 1. The rubber ring 205 is manually fitted onto the inner wall of the groove 203, and then the fixing sleeve 206 is fitted onto the surface of the cable body 1. This facilitates the confinement of the steel wire 202 within the locking grooves 201. The cable body 1 has uniformly formed fixing grooves 204 on its surface. A rubber block 207 is provided on the inner wall of the fixing groove 204. The end of the rubber block 207 away from the fixing groove 204 is fixedly connected to the inner wall of the fixing sleeve 206, pressing the rubber block 207 into the fixing groove 204. This can effectively restrict the fixing sleeve 206 on the surface of the cable body 1. A positioning groove 208 is formed on the inner wall of the groove 203. A rubber rod 209 is provided on the inner wall of the positioning groove 208. A rubber ball 210 is fixedly connected to the bottom of the rubber rod 209. The rubber ball 210 is located at the bottom of the inner wall of the positioning groove 208, pressing the rubber rod 209 into the positioning groove 208 and pressing the rubber ball 210 into the bottom of the inner wall of the positioning groove 208. This can effectively prevent the steel wire 202 from sliding on the inner wall of the locking groove 201.

[0029] Reference Figure 4The limiting device 3 includes two fixing rings 301, which are respectively fitted onto the surfaces of the two ends of the cable body 1 that are close to each other. A connecting groove 304 is provided on one side of each fixing ring 301. A connecting strip 305 is slidably connected to the inner wall of the connecting groove 304. The end of the connecting strip 305 away from the connecting groove 304 is fixedly connected to one side of the other fixing ring 301. When using the limiting device 3, the two fixing rings 301 are respectively fitted onto the surfaces of the two ends of the cable body 1 that are close to each other, and then the connecting strip 305 is controlled to slide on the inner wall of the connecting groove 304. This facilitates the restriction of the two ends of the cable body 1 together, making it easier to connect the two ends of the cable body 1 together later. A rubber ring 302 is fixedly connected to the inner wall of the fixing ring 301. Notches 303 are evenly provided on the surface of the rubber ring 302. When the fixing ring 301 is fitted onto the surface of the cable body 1... When the rubber ring 302 is pressed firmly against the surface of the cable body 1, the fixing ring 301 is effectively restricted to the surface of the cable body 1. The notch 303 allows the rubber ring 302 to deform more. A bolt 306 is inserted through one side of the connecting strip 305. The bolt 306 is threaded through the fixing ring 301 on the side away from the connecting strip 305. The bolt 306 can be manually rotated, which facilitates the control of the connecting strip 305 sliding on the inner wall of the connecting groove 304. A damping rod 307 is fixedly connected to the inner wall of the two fixing rings 301. A spring 308 is sleeved on the surface of the damping rod 307. The two ends of the spring 308 are fixedly connected to the two opposite sides of the two fixing rings 301. By pulling the fixing rings 301 towards the middle through the spring 308, the ends of the two fixing rings 301 away from the connecting strip 305 can be restricted together.

[0030] Working principle: When using power cables, high-voltage electricity can be effectively transported. The main function of power cables is to transmit and distribute electrical energy, ensuring the normal operation of the power system. They are used in urban and rural power systems to connect power plants and substations, transporting high-voltage power from power plants to substations, and then distributing the electricity to households, businesses, and industrial users via low-voltage cables. When using protective device 2, manually press the steel wire 202 into the inside of the locking groove 201, manually fit the rubber ring 205 onto the inner wall of the groove 203, press the rubber rod 209 into the inside of the positioning groove 208, and press the rubber ball 210 into the bottom of the inner wall of the positioning groove 208. This effectively prevents the steel wire 202 from sliding on the inner wall of the locking groove 201. Press the rubber block 207 into the inside of the fixing groove 204, which effectively restricts the fixing sleeve 206 on the surface of the cable body 1, thus facilitating the restriction of the steel wire 202 in the locking groove 201. The internal structure of 01 can strengthen the surface strength of the cable body 1 to a certain extent, thus preventing the cable body 1 from bending. When using the limiting device 3, the two fixing rings 301 are respectively fitted onto the surfaces of the two ends of the cable body 1 that are close to each other. When the fixing rings 301 are fitted onto the surface of the cable body 1, the rubber rings 302 are well squeezed against the surface of the cable body 1, thus effectively restricting the fixing rings 301 to the surface of the cable body 1. The notch 303 allows the deformation range of the rubber rings 302 to become larger. The bolt 306 is manually controlled to rotate, which facilitates the control of the connecting strip 305 sliding on the inner wall of the connecting groove 304, thus facilitating the restriction of the two ends of the cable body 1 together. The fixing rings 301 are pulled towards the middle by the spring 308, which allows the ends of the two fixing rings 301 away from the connecting strip 305 to be restricted together, thus facilitating the subsequent connection of the two ends of the cable body 1 together.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
