Description

Technical Field

[0001] This utility model relates to the field of electrical wiring protection technology, and in particular to an electrical wiring insulation protection device for power plants. Background Technology

[0002] Power plants are a core component of the power supply system, responsible for generating electricity to meet society's electricity needs. Within a power plant, the electrical wiring network plays a crucial role, connecting generators, transformers, switchgear, and other electrical equipment to ensure the transmission, distribution, and control of electrical energy. However, these electrical wiring systems have potential insulation problems that can lead to electrical faults, fires, and even personal safety risks.

[0003] Patent document CN221240073U discloses an electrical wiring insulation protection device for power plants. The device includes a main body, which is a circular hollow roller design. An internal temperature gauge and a power starter block are both mounted on the surface of the main body, facilitating observation during use. A heating coil is installed on the inner wall of the main body. This design ensures that the device can quickly and effectively insulate exposed wiring surfaces without posing a risk of open flame exposure. Furthermore, it can be used to insulate wiring of varying lengths, effectively guaranteeing the device's efficiency and providing a quick and easy operating experience.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: the use of hollow roller-type protective devices can only cover the surface of exposed lines of a specified specification. However, when providing insulation protection for exposed lines of larger or smaller specifications, the outer shell of the roller-type device is difficult to close or there are gaps between it and the smaller exposed lines, resulting in poor practical applicability. In addition, after achieving the coverage of the exposed lines, the lack of a positioning structure causes the protective device to move along the length of the line during long-term use, leading to the exposure of the stripped ends of the lines. Therefore, an electrical wiring insulation protection device for power plants is designed to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide an electrical wiring insulation protection device for power plants to address the above-mentioned technical problems, thereby solving the technical issues of inconvenience in using it for different specifications of lines and the ease with which it can be moved or misaligned.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An electrical wiring insulation protection device for power plants includes a protective shell, an insulating layer, and a set of wiring, wherein the stripped sections of the set of wiring are intertwined to form a connection node, and further includes:

[0008] An elastic mechanism is provided between the protective shell and the insulating layer, the elastic mechanism being able to expand the insulating layer to cover the connection node;

[0009] Two tensioning mechanisms, connected between the protective shell and the insulating layer, are capable of relative movement to shrink the insulating layer and wrap it around the connection node; and

[0010] Two limiting mechanisms are respectively located at both ends of the protective shell, and each consists of a clamp that can be fixed to the wiring and a connecting plate that can drive the clamp to approach the wiring.

[0011] As a preferred embodiment of the electrical wiring insulation protection device for power plants provided by this utility model, the elastic mechanism is composed of elastic bodies arranged at equal intervals along the inner circumference and axial direction of multiple protective shells, and the multiple elastic bodies are all rubber strips or tension springs.

[0012] As a preferred embodiment of the electrical wiring insulation protection device for power plants provided by this utility model, both of the tensioning mechanisms consist of multiple pull straps equidistantly connected to the insulation layer along the length of the protective shell, a clamping strap integrated with one or two of the pull straps, and a blocking part capable of fixing any length of the pull strap.

[0013] In a preferred embodiment of the electrical wiring insulation protection device for power plants provided by this utility model, the pull straps of the two tensioning mechanisms are arranged alternately, and the pull strap of one of the tensioning mechanisms passes around the lower outer side of the insulation layer in the open state and passes through the top of the protective shell to connect with the clamping tape. The lower outer side of the insulation layer is provided with a groove that allows the pull strap to penetrate into the insulation layer.

[0014] As a preferred embodiment of the electrical wiring insulation protection device for power plants provided by this utility model, the tape includes a first tape body, a set of teeth disposed inside the first tape body and capable of fixedly engaging with the blocking part, and a pull body capable of moving the first tape body and its set of teeth within the blocking part.

[0015] As a preferred embodiment of the electrical wiring insulation protection device for power plants provided by this utility model, the damping part includes a first base fixed to the outside of the protective shell, a stop tooth that is telescopically moved within the first base by a set of springs and can be limited on a set of locking teeth, and a set of pushers that can drive the stop tooth to move within the first base.

[0016] As a preferred embodiment of the electrical wiring insulation protection device for power plants provided by this utility model, the clamp includes a second base rotatably connected to one end of a connecting plate away from the protective shell, a second belt body with one end fixed to the second base body and the other end capable of extending into the second base body, and a worm gear capable of driving the second belt body to advance into the second base body. A plurality of limiting grooves capable of cooperating with the worm gear are equally spaced on the second belt body.

[0017] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0018] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0019] This utility model provides an electrical wiring insulation protection device for power plants. Through a stretching mechanism, the insulation layer can be contracted to cover the stripped section of the line of any specification, achieving the insulation protection effect of the existing method of shrinking insulation sleeve by heating. Moreover, no other auxiliary tools are required during operation. The insulation layer can be quickly and conveniently contracted to cover the line by simply driving the stretching mechanism.

[0020] This utility model provides an electrical wiring insulation protection device for power plants. By using a limiting mechanism, the insulation layer is connected and fixed to the part of the line away from the stripped section, based on the insulation layer covering the stripped section of the line. This prevents the insulation layer from moving and dislodging due to the passage of time or external influences, thus exposing the stripped section of the line. This ensures that the stripped section is permanently protected by the insulation of the device. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] like Figure 1 and Figure 2As shown, this type of electrical wiring insulation protection device for power plants includes a protective shell 1, an insulating layer 2, a set of wiring 3, an elastic mechanism 5, two tensioning mechanisms 6, and two limiting mechanisms 7. The insulating layer 2 is located inside the protective shell 1, and under the connection of the elastic mechanism 5, the insulating layer 2 is connected and restricted to form a cylindrical shape as shown in the figure. Thus, the stripped sections of the set of wiring 3 can pass through the connecting nodes 4 formed by intertwining with each other, which are located inside the insulating layer 2. Under the action of the tensioning mechanism 6 located between the protective shell 1 and the insulating layer 2, the insulating layer 2 can be driven to shrink relatively. The shrinking insulating layer 2 wraps around and covers the connecting nodes 4, thereby achieving insulation protection for the connecting nodes 4.

[0035] Two limiting mechanisms 7 are respectively connected to both ends of the protective shell 1. After the insulation layer 2 achieves insulation protection for the connection node 4, they are fixed to the part of a set of wiring 3 away from the connection node 4, thereby strengthening the position of the insulation layer 2 on the connection node 4, that is, making it difficult for the insulation layer 2 to detach from the connection node 4 and preventing the connection node 4 from being exposed.

[0036] like Figure 3 As shown, and for reference Figure 1 and Figure 2 The elastic mechanism 5 is composed of multiple elastic bodies 51 arranged equidistantly along the inner circumference and axial direction of the protective shell 1. The insulating layer 2 is connected and restricted by the multiple elastic bodies 51 at multiple angles and positions. It is originally a flat single layer shape, but is connected and stretched and the two ends are closed close together. Thus, a set of wiring nodes 4 that can accommodate a certain specification range of wiring 3 are formed in the insulating layer 2. The elastic bodies 51 can connect and restrict the shape formed by the insulating layer 2, and can also be stretched and deformed under external force (e.g., tensioning mechanism 6). That is, the elastic body 51 is stretched and lengthened, so the insulating layer 2 shrinks with the deformation of the elastic body 51 and according to the direction of the force. At the same time, the accommodating space formed in the insulating layer 2 shrinks and can be tightly fitted to the outside of the connection node 4. In some embodiments, the elastic body 51 is a rubber strip or a tension spring, or other components that can be stretched and deformed under force and shrink and reset when no force is applied.

[0037] like Figure 4 As shown, and for reference Figure 1 and Figure 2Both tensioning mechanisms 6 consist of multiple pull straps 61 equidistantly connected to the insulating layer 2 along the length of the protective shell 1, a retaining strap 62 integrally connected to one or two pull straps 61, and a stopping part 63 capable of fixing any length of the pull strap 61. Specifically, the pull straps 61 of the two tensioning mechanisms 6 are arranged in an alternating vertical arrangement. Taking one as an example, one end of the pull strap 61 passes through one side of the insulating layer 2 and is integrally connected to the other side, while the other end of the pull strap 61 passes around the lower outer side of the insulating layer 2 in the open state, and extends upward through the protective shell 1 to connect with the retaining strap 62 located on the outside. Furthermore, the lower outer side of the insulating layer 2 has a locking mechanism that allows for... The pull strap 61 is able to penetrate the groove in the insulating layer 2. When the insulating layer 2 is pulled by the clip 62 and the pull strap 61, one end of the insulating layer 2 connected to the pull strap 61 will move towards the other end or inward or outward to overlap. The overlapping ends of the insulating layer 2 will reduce the accommodating space inside the insulating layer 2 until it is reduced to the state of being able to wrap and cover the connecting node 4. It should be noted that a protruding edge is provided on one side of the insulating layer 2. The protruding edge can cause the other side to move into the insulating layer 2 when it moves close to the protruding edge, so as to achieve the state of overlapping of the two ends to reduce the internal space.

[0038] As the space inside the insulation layer 2 shrinks, the elastic mechanism 5 will be stretched and deformed by the movement of the insulation layer 2. When the insulation layer 2 is not pulled by the clip 62 and the pull strap 61, the elastic mechanism 5 will elastically reset, allowing the insulation layer 2 to reset and form a state with a larger internal space, so that the connection node 4 that is not insulated can be inserted.

[0039] While the cassette 62 and the pull strap 61 are moving, the cassette 62 will move within the blocking part 63. The blocking part 63 allows the cassette 62 to move in only one direction and prevents the cassette 62 from moving in the opposite direction within the blocking part 63. As the cassette 62 continues to move on the blocking part 63, the insulating layer 2 is contracted. When the cassette 62 stops moving, the blocking part 63 maintains the state of the insulating layer 2 being contracted and locks the connection state of the tightly fitting connecting node 4 after the insulating layer 2 is contracted, thus providing insulation protection.

[0040] Furthermore, such as Figure 5 As shown, and for reference Figure 1 , Figure 2 and Figure 4The cassette 62 includes a first cassette body 621, a set of teeth 622 disposed inside the first cassette body 621 and capable of fixedly engaging with the blocking part 63, and a pull body 623 capable of moving the first cassette body 621 and its set of teeth 622 within the blocking part 63; the blocking part 63 includes a first base 631 fixed to the outside of the protective shell 1, a stop tooth 633 that is telescopically movable within the first base 631 by a set of springs 632 and can be limited on the set of teeth 622, and a set of push bodies 634 capable of moving the stop tooth 633 within the first base 631;

[0041] The first belt 621 and its set of locking teeth 622 are continuously moved through the first base 631 by the pull body 623. During the movement, since the locking teeth 622 and the blocking teeth 633 are triangular, and there is a groove between the blocking teeth 633 to retain the blocking teeth 633, the locking teeth 622 continuously move downward, which will drive the blocking teeth 633 to squeeze the spring 632, so that the blocking teeth 633 regularly extend and retract in the first base 631. That is, the extension and retraction movement is: the blocking teeth 633 contact the locking teeth 622 and squeeze the spring 632 to move inward in the first base 631 - the blocking teeth 633 do not contact the locking teeth 622 and the spring 632 resets, causing the blocking teeth 633 to extend and retract outward and be located in the groove between the blocking teeth 633. When the first belt 621 does not move, since the blocking teeth 633 are located in the groove between the blocking teeth 633, the first belt 621 is restricted from disengaging and moving in the opposite direction.

[0042] When the entire tape 62 needs to be positioned in the blocking part 63, so as not to apply a contraction force to the insulating layer 2, the pusher 634 drives the stop tooth 633 to squeeze the spring 632 and move the stop tooth 633 into the first base 631, so that the stop tooth 633 does not contact the locking tooth 622 of the first tape body 621, thereby the tape 62 formed by the first tape body 621 and the locking tooth 622 can be dislocated in the blocking part 63 including the first base 631.

[0043] like Figure 6 As shown, and for reference Figure 1 and Figure 2 Taking one of the limiting mechanisms 7 as an example, it consists of a clamp 71 that can be fixed to the wiring 3 and a connecting plate 72 that can drive the clamp 71 to approach the wiring 3; after the clamp 71 approaches and is fixed to the wiring 3 under the drive, the insulation layer 2 can stay outside the connection node 4 for a long time.

[0044] Furthermore, such as Figure 7 As shown, and for reference Figure 6The clamp 71 includes a second base 711 rotatably connected to one end of the connecting plate 72 away from the protective shell 1, a second belt 712 with one end fixed to the second base 711 and the other end able to extend into the second base 711, and a worm 713 capable of driving the second belt 712 to advance into the second base 711. Multiple limiting grooves 714 that can cooperate with the worm 713 are equally spaced on the second belt 712.

[0045] One end of the second belt 712 is placed inside the second base 711, and the limiting groove 714 on the side of the second belt 712 is sleeved outside the spiral path of the worm 713. As the worm 713 rotates, the limiting groove 714 on the second belt 712 will contact the worm 713 one after another. At the same time, the second belt 712 continues to move and penetrates the second base 711, so that the diameter of the second belt 712 is reduced, so that it can be wrapped and fixed outside the wiring 3.

[0046] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
