Description

Technical Field

[0001] This invention belongs to the field of power engineering, specifically a safety protection device for power generation lines. Background Technology

[0002] A power transmission line is a line used to transmit electrical energy between power plants, substations, and power users. It is an important component of the power supply system, responsible for transmitting and distributing electrical energy.

[0003] Since the power generation line is located outdoors, it is subject to damage due to the influence of external environmental factors. After the power generation line is damaged, wiring tools are usually used to reconnect the line and then continue to use it.

[0004] As society progresses, people's demands for safety are constantly increasing. In order to reduce the number of times power generation lines are damaged, protection is usually provided at the connection points of the lines. For this purpose, people have invented power generation line safety protection devices.

[0005] However, research has revealed certain drawbacks in the use of the aforementioned power generation line safety protection devices.

[0006] The existing safety protection device for power generation lines is a combination of tape and sleeve. When in use, the tape is wound around the connection of the power generation line, and then the connection is sleeved with a sleeve and the position of the sleeve is fixed.

[0007] This type of power generation line safety protection device is not comprehensive in protecting the power generation line. It protects the connection of the power generation line, but it cannot limit the connection of the power generation line. When the power generation line swings, the connection is subjected to great force and will pull against each other, and the connection is prone to secondary damage.

[0008] The current power generation line safety protection device has a relatively simple protective effect, only protecting the joint position and unable to provide any other protective effect, which does not meet people's usage requirements. Therefore, we have proposed a power generation line safety protection device. Summary of the Invention

[0009] To overcome the shortcomings of the prior art, this application provides a power generation line safety protection device, which includes a corrugated pipe structure and a line clamping device structure. During use, the internal reserved setting of the power generation line protection component and the line clamping device clamp the line, which can limit the position of the line. The impact on the line joints is small during the shaking of the line, and it has a certain buffer space. The impact of thermal expansion and contraction on the power generation line safety protection device is small, which can extend the service life of the power generation line.

[0010] The technical solution adopted by this application to solve its technical problem is:

[0015] The corrugated pipe, the limiting sleeve, and the line opening are coaxially arranged.

[0016] This invention describes a power generation line safety protection device, which includes a corrugated pipe structure and a line clamping device structure. In use, the power generation line protection component has internal reserved settings, and the line clamping device clamps the line, which can limit the position of the line. During the shaking of the line, the impact on the line joints is small, and it has a certain buffer space. The thermal expansion and contraction have a small impact on the power generation line safety protection device, which can extend the service life of the power generation line.

[0017] Preferably, the limiting frame includes a horizontal plate, a support rod, and a limiting plate;

[0018] A mounting box is provided on the end face of the horizontal plate away from the protection components of the power generation line;

[0020] The wiring opening is provided on the limiting plate, and the lower end of the support rod is fixedly connected to the outer surface of the limiting plate.

[0021] The elastic limiting component is disposed between the two sets of horizontal plates, and the end face of the corrugated pipe is fixedly connected to the limiting plate.

[0022] The elastic limiting component applies an inward force to the horizontal plate, limiting the distance of the power generation line protection components and preventing the bellows from being damaged due to excessive stretching during line swaying.

[0023] The combination of the horizontal plate and the elastic limiting component limits the position of the power generation line protection component, which can support the power generation line and reduce the pressure at the connection of the power generation line.

[0024] Preferably, the elastic limiting assembly includes several sets of elastic limiting components, each of which includes a shock-absorbing spring and a telescopic rod. The shock-absorbing spring is disposed outside the telescopic rod, and both ends of the shock-absorbing spring and both ends of the telescopic rod are respectively fixedly connected to two sets of horizontal plates.

[0025] The shock-absorbing springs and telescopic rods work together to cushion the impact and limit the direction of movement.

[0026] Preferably, the power generation line protection assembly includes a mounting ring and a power generation line joint protection component;

[0027] There are two sets of mounting rings, which are connected to the bellows.

[0028] The protective components for the power line joints are installed between two sets of mounting rings.

[0030] Preferably, the protective component for the power generation line connector includes a lower base and an upper cover plate;

[0031] The two ends of the lower body are respectively fixedly connected to two sets of mounting rings;

[0036] The card slot is located on the lower body;

[0037] The snap-fit ​​spring is installed on the lower end face of the upper cover plate and snaps into the snap-fit ​​groove.

[0038] When in use, the snap-fit ​​groove and snap-fit ​​spring cooperate with each other. When in use, the lower seat and the upper cover are facing each other, and the lower seat is pressed so that the upper cover is in contact with the lower seat. At this time, the snap-fit ​​spring is snapped into the snap-fit ​​groove to achieve a seal.

[0039] The connection between the lower seat and the upper cover can be fitted with sealing strips or other sealing structures, which improves the performance.

[0040] This invention describes a safety protection device for power generation lines, which includes a protective component for the power generation line connector. The lower body of the protective component is detachably connected to the upper cover plate via a snap-fit ​​assembly. In use, the snap-fit ​​spring in the snap-fit ​​assembly can be pried open to separate the snap-fit ​​spring from the snap-fit ​​groove, and then the upper cover plate can be pulled to directly inspect the connector of the power generation line. This makes maintenance relatively convenient.

[0042] The curved rubber strip further defines the position of the power lines at both ends of the power line joint, reduces the impact of the corrugated pipe stretching and contracting on the power line joint, extends the service life of the power line joint, and thus reduces the number of maintenance operations.

[0043] Preferably, the line clamping device includes shape memory metal plates, and the number of shape memory metal plates is several groups. The several groups of shape memory metal plates are all installed on the inner surface of the limiting sleeve near one end, and the several groups of shape memory metal plates are arranged in a ring.

[0045] When in use, rotating the limiting sleeve causes the shape memory metal plate to contact different positions with the annular ring, causing the shape memory metal plate to tilt and press against the surface of the power generation line, thus achieving the limiting of the limiting sleeve.

[0046] Rubber strips can be used on the end face of the memory metal plate. The rubber strips can protect the power generation circuit and prevent damage to the circuit's outer sheath.

[0066] This application provides a power line safety protection device that addresses the shortcomings of existing power line safety protection devices, which combine tape and sleeve structures. In these devices, the tape is wound around the connection point of the power line, and then the sleeve is used to secure the connection and fix its position. This type of device is not comprehensive in its protection of the power line; while it protects the connection point, it cannot limit its movement. When the power line swings, the connection point experiences significant force, leading to pulling and secondary damage. This invention's power line safety protection device incorporates a corrugated pipe structure and a line clamping device. During use, the internal design of the power line protection components and the line clamping device effectively limit the line's position. This minimizes the impact on the line joints during shaking and provides a buffer space, reducing the impact of thermal expansion and contraction on the power line safety protection device, thus extending the service life of the power line and resulting in better performance.

[0067] Example 1:

[0068] A power generation line safety protection device, such as Figures 1-7 As shown, it includes a limit frame 1, a power generation line protection assembly, and a limit sleeve 4;

[0069] There are two sets of limiting frame 1, and an elastic limiting component is provided between the two sets of limiting frame 1. The limiting frame 1 is provided with a line through hole 2. Both ends of the power generation line protection component are provided with corrugated pipes 3, and one end of the corrugated pipe 3 is connected to the limiting frame 1. There are two sets of limiting sleeves 4. The limiting sleeves 4 are located on the side of the limiting frame 1 away from the power generation line protection component. The limiting sleeves 4 are provided with a line clamping device inside.

[0070] Among them, the corrugated pipe 3, the limiting sleeve 4, and the line opening 2 are coaxially arranged.

[0071] The corrugated pipe 3, the limiting sleeve 4, and the line opening 2 are connected, and the power generation line can directly pass through the corrugated pipe 3, the limiting sleeve 4, and the line opening 2 when in use.

[0072] The line clamping device includes a memory metal plate 15. The number of memory metal plates 15 is several groups. The several groups of memory metal plates 15 are all installed on the inner surface of the limiting sleeve 4 near one end. The several groups of memory metal plates 15 are arranged in a ring.

[0073] The outer surface of the limiting plate 7 is provided with an annular groove 16, and one end of the limiting sleeve 4 is rotatably connected to the annular groove 16 by a thread. The limiting plate 7 is provided with an annular ring 17, which is in close contact with the outer surface of the memory metal plate 15.

[0074] The shape memory metal plate 15 is arranged in a ring shape, which can contact the power generation line from all directions. It has a wide contact area with the power generation line and high stability when fixed.

[0075] When in use, rotating the limiting sleeve 4 causes the shape memory metal plate 15 to contact the annular ring 17 at different positions, causing the shape memory metal plate 15 to be tilted and press against the surface of the power generation line, thereby achieving the limiting of the limiting sleeve 4.

[0076] The end face of the memory metal plate 15 can be made of rubber strips. The rubber strips can protect the power generation line and prevent damage to the surface of the power generation line.

[0077] This invention describes a power generation line safety protection device, which includes a corrugated pipe structure and a line clamping device structure. During use, the power generation line protection component has internal reserved settings, and the line clamping device clamps the line, which can limit the position of the line. The impact on the line joints is small during the shaking of the line, and it also has a certain buffer space. The impact of thermal expansion and contraction on the power generation line safety protection device is small, which can extend the service life of the power generation line.

[0078] Example 2:

[0079] Based on Example 1, such as Figures 1-7 As shown, this embodiment is the structure of the limiting frame 1;

[0080] The limiting frame 1 includes a horizontal plate, a support rod 6, and a limiting plate 7;

[0081] A mounting box 5 is provided on the end face of the horizontal plate away from the power generation line protection component; there are several sets of support rods 6, and the upper end of the support rod 6 is fixedly connected to the lower end face of the horizontal plate; the line through-hole 2 is opened on the limiting plate 7, and the lower end of the support rod 6 is fixedly connected to the outer surface of the limiting plate 7.

[0082] The elastic limiting component is set between the two sets of horizontal plates, and the end face of the corrugated pipe 3 is fixedly connected to the limiting plate 7.

[0083] The elastic limiting component applies a force to the horizontal plate inward, limiting the distance of the power generation line protection component and preventing the bellows 3 from being overstretched and damaged during line swaying.

[0084] The combination of the horizontal plate and the elastic limiting component limits the position of the power generation line protection component, which can support the power generation line and reduce the pressure at the connection of the power generation line.

[0085] The elastic limiting assembly includes several sets of elastic limiting components, each including a shock-absorbing spring 8 and a telescopic rod 9. The shock-absorbing spring 8 is disposed outside the telescopic rod 9, and both ends of the shock-absorbing spring 8 and both ends of the telescopic rod 9 are fixedly connected to two sets of horizontal plates respectively.

[0086] The shock-absorbing spring 8 and the telescopic rod 9 work together to buffer and limit the direction of movement.

[0087] The power line protection assembly includes mounting ring 10 and power line joint protection components;

[0088] There are two sets of mounting rings 10, and the mounting rings 10 are connected to the bellows 3.

[0089] The protective components for the power line joint are installed between the two sets of mounting rings 10.

[0090] Protective components for generator line joints serve to protect the generator line joints and prevent external debris from coming into contact with the connection points.

[0091] The protective components for the power generation line joint include a lower base 11 and an upper cover 12;

[0092] The two ends of the lower seat 11 are respectively fixedly connected to two sets of mounting rings 10;

[0093] The upper cover plate 12 is located at the upper end of the lower base body 11;

[0094] The lower body 11 is detachably connected to the upper cover 12 via a snap-fit ​​assembly.

[0095] The lower seat 11 and the upper cover 12 are detachably connected, which makes it easy to disassemble and assemble, and allows maintenance personnel to regularly check the condition of the power generation line joints.

[0096] The snap-fit ​​assembly includes several sets of snap-fit ​​components, each of which includes a snap-fit ​​slot 13 and a snap-fit ​​spring 14.

[0097] The card slot 13 is formed on the lower base 11;

[0098] The snap-fit ​​spring 14 is installed on the lower end face of the upper cover plate 12 and snaps into the snap-fit ​​groove 13.

[0099] When in use, the snap-fit ​​groove 13 and the snap-fit ​​spring 14 cooperate with each other. When in use, the lower seat 11 and the upper cover 12 are placed opposite each other, and the lower seat 11 is pressed so that the upper cover 12 is attached to the lower seat 11. At this time, the snap-fit ​​spring 14 is snapped into the snap-fit ​​groove 13 to achieve a seal.

[0100] The connection between the lower seat 11 and the upper cover plate 12 can be fitted with sealing structures such as sealing strips, which improves the performance.

[0101] A groove can also be provided at the connection between the lower seat 11 and the upper cover plate 12. Using the groove in conjunction with sealing strips and other sealing structures will improve the performance.

[0102] This invention describes a safety protection device for power generation lines, which includes a protective component for power generation line joints. The lower seat 11 of the protective component is detachably connected to the upper cover 12 via a snap-fit ​​assembly. In use, the snap-fit ​​spring 14 in the snap-fit ​​assembly can be pried open to separate the snap-fit ​​spring 14 from the snap-fit ​​groove 13. Then, the upper cover 12 can be pulled to directly inspect the joint of the power generation line. This device is easy to maintain and can reduce the workload of maintenance personnel.

[0103] Arc-shaped rubber strips 18 are provided on the upper end face of the lower seat body 11 and the lower end face of the upper cover plate 12 near both ends. The end face of the arc-shaped rubber strip 18 on the lower seat body 11 is in close contact with the end face of the arc-shaped rubber strip 18 on the upper cover plate 12.

[0104] The arc-shaped rubber strip 18 further defines the position of the power lines at both ends of the power line joint, reduces the impact of the corrugated pipe 3 on the power line joint when it stretches and contracts, extends the service life of the power line joint, and thus reduces the number of maintenance operations.

[0105] Example 3:

[0106] Based on Example 2, such as Figures 1-7 As shown, this embodiment illustrates the structure of the mounting box 5;

[0107] The installation box 5 is equipped with a rope reel, one end of the rope on the rope reel passes through the end face of the installation box 5, and the outer surface of the installation box 5 is equipped with a limiting component for limiting the position of the rope.

[0108] A rope reel can automatically wind up a rope. After use, simply loosen the other end of the rope, and it will automatically wind up again, making it very convenient to use.

[0109] When in use, the two ends of the rope reel are connected to fixed structures such as cable racks, which can tighten and support the entire device and support the cable.

[0110] One end of the rope reel is equipped with a stop to prevent the rope from being completely wound into the installation box 5. The stop is equipped with a pull ring, which makes it easy to pull out the rope, making it convenient to use.

[0111] The limiting assembly includes a slide 19, a slider 20, and a compression spring 22;

[0112] The slide groove 19 is formed on the outer surface of the mounting box 5; the slider 20 is slidably installed in the slide groove 19, and the outer surface of the slider 20 is provided with an arc-shaped pressure block 21 for pressing the rope on the rope rewinder;

[0113] The two ends of the compression spring 22 are fixedly connected to the upper end face of the slider 20 and the inner top surface of the groove 19, respectively.

[0114] This invention describes a safety protection device for power generation lines, which includes a rope reel and a limiting component. In use, the telescopic extension of the rope reel can be connected to a nearby fixed structure to limit the position of the safety protection device for the power generation lines, thereby supporting the power generation lines and improving their stability. The limiting component allows workers to easily adjust the rope length, making it convenient to use.

[0115] It should be noted that, in use, the damaged power generation line of this invention is passed through the limiting sleeve 4, the line through-hole 2, the corrugated pipe 3 and the mounting ring 10, and extended into the interior of the lower seat 11. Then, the line is properly connected, and the upper cover plate 12 is covered, so that the snap-fit ​​spring piece 14 on the upper cover plate 12 is inserted into the snap-fit ​​groove 13 on the lower seat 11 and snaps in place. After snapping in place, the arc-shaped rubber strips 18 are opposite each other, thereby fixing the position of the power generation line. Then, the power generation line is squeezed from both ends, and a part of the power generation line is inserted into the space where the corrugated pipe 3 is located for expansion and contraction buffering. Then, the limiting sleeve 4 is rotated to change the position of the memory metal plate 15, so that the memory metal plate 15 contacts the annular ring 17, and the memory metal plate 15 is tilted and snapped onto the power generation line, thereby limiting the power generation line.

[0116] Before or after use, slider 20 can be slid to pull the rope, which can then be tied to a nearby building or cable rack to support the line.

[0117] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
