Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment protection technology, and in particular to an insulating protective cover for a live-installed distribution network parallel trench clamp. Background Technology
[0002] In power distribution network transmission lines, the parallel groove clamp is a key component for connecting conductors. It is in a complex outdoor environment for a long time, and its safe and stable operation is directly related to the power supply reliability of the power distribution network.
[0003] However, in actual operation, parallel groove clamps are susceptible to interference from various factors. Birds often nest near parallel groove clamps, and the twigs, wires, and other materials used for nesting may fall between the clamps or conductors, causing short circuits. Simultaneously, bird droppings accumulating on the clamp surface can adversely affect its insulation performance. Rodents such as rats may gnaw on the insulation of the clamps or conductors, causing insulation damage and leading to line faults. Furthermore, lightweight floating objects such as kites, plastic films, and strips of cloth can easily become entangled in the clamps or conductors under wind conditions, causing line tripping accidents. Moreover, corrosive substances such as acid rain and salt spray accelerate the oxidation and aging of the metal components of the clamps, reducing their mechanical strength and conductivity, and shortening their service life. Additionally, with increased operating time, the clamps may loosen, leading to increased contact resistance and localized overheating. If not detected and addressed promptly, this can cause more serious line faults. Therefore, protective structures are needed to protect the clamps.
[0004] However, traditional parallel trench clamp protection measures have obvious drawbacks: on the one hand, installation and maintenance often require power outages, which can affect the normal power supply of the distribution network, reduce power supply reliability, and cause inconvenience to industrial production and residents' lives; on the other hand, traditional protection devices can only provide simple physical isolation and cannot monitor the operating temperature of the parallel trench clamp in real time, making it difficult to detect potential faults such as local overheating in advance; in addition, some fully enclosed protection designs can cause water and dust to accumulate inside the device, which not only hinders the heat dissipation of the parallel trench clamp, but also affects the normal operation of detection work such as infrared thermometry, making it difficult to grasp the operating status of the clamp in a timely manner.
[0005] Therefore, it is necessary to provide an insulating protective cover for live-installed distribution network and trench clamps to solve the above-mentioned technical problems. Utility Model Content
[0006] This utility model provides an insulating protective cover for live-installed parallel trench clamps in power distribution networks, which solves the problems of traditional parallel trench clamp protection measures requiring power outages for installation, inability to monitor temperature in real time, and limited protective effects.

An octagonal opening is opened at the bottom of the first sheath and the second sheath. A temperature measuring element is embedded inside the first sheath and the second sheath. Multiple locking components are provided on the outer side of the first sheath and the second sheath for limiting the distance between the first sheath and the second sheath.

[0014] Preferably, the bird deterrent assembly includes a support rod, a fixing block, multiple connecting rods, multiple air guides, and multiple reflectors. The fixing block is rotatably connected to the top of the support rod, the multiple connecting rods are fixedly installed on the side of the fixing block, the multiple air guides are respectively fixedly installed on one end of the multiple connecting rods, and the multiple reflectors are respectively fixedly installed on the inner side of the multiple air guides.

[0016] Preferably, a metal plate is fixedly installed on the bottom of the inner side of the limiting frame, and a magnetic plate is fixedly installed on the bottom of the mounting frame, with the magnetic plate being magnetically attached to the top of the metal plate.

Detailed Implementation
[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0034] First Embodiment
[0035] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of an insulating protective cover for a live-installed distribution network parallel trench clamp provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure; Figure 3 for Figure 2 The diagram shows another perspective of the structure; Figure 4 for Figure 1The enlarged schematic diagram of part A is shown. An insulating protective cover for a live-installed distribution network parallel trench clamp includes: a first sheath 1 and a second sheath 2, the first sheath 1 and the second sheath 2 being disposed opposite each other, each having a central hole 3 at one opposite end, each having an octagonal opening 4 at its bottom, each having a temperature measuring element 6 embedded inside, and each having multiple engaging components 5 on its outer surface for limiting the movement between the first sheath 1 and the second sheath 2.
[0036] Each of the multiple engaging components 5 includes a limiting frame 51, an elastic sheet 52, and a snap-fit block 53. The limiting frame 51 is fixedly installed on the side of the first protective sleeve 1, the elastic sheet 52 is fixedly installed on the side of the second protective sleeve 2, and the snap-fit block 53 is fixedly connected to one end of the elastic sheet 52 and snaps into the side of the limiting frame 51.
[0037] The first sheath 1, the second sheath 2, and the temperature measuring element 6 are all made of transparent material.
[0038] One end of the octagonal opening 4 extends to the bottom of the central hole 3.
[0039] Both the first sheath 1 and the second sheath 2 are transparent insulating sheaths made of high light transmittance silicone rubber composite material, which also has flame retardant (UL94V-0 grade), high temperature resistance and anti-aging properties, ensuring that they do not obstruct the equipment's infrared temperature measurement window and the opening and closing indicator.
[0040] Octagonal Opening Design 4: The opening at the bottom of the sheath has an octagonal gradient structure, which can adapt to the installation angle of 0°-90° through elastic deformation, supports live work, and shortens the installation time to less than 7 minutes.
[0041] Temperature sensing element 6: Microencapsulated thermochromic material is embedded on the surface of the sheath, and three temperature thresholds are set (80℃ black warning, 90℃ deep black warning, 100℃ carbonization failure) to achieve irreversible color change to mark the risk of overheating.
[0042] The working principle of the insulating protective cover for the live-lined distribution network parallel trench clamp provided by this utility model is as follows:
[0043] During installation, the octagonal opening 4 allows the first sheath 1 and the second sheath 2 to be inserted into the cables on both sides of the parallel groove clamp without disassembling the cables, enabling live installation. After insertion, the snap-fit block 53 of the snap-fit assembly 5 engages with the limiting frame 51, fixing the first sheath 1 and the second sheath 2 together. The elastic force generated by the deformation of the elastic sheet 52 allows the two to fit tightly together, encasing the parallel groove clamp and providing insulation and protection. The transparent first sheath 1, second sheath 2, and temperature sensor 6 facilitate observation of the parallel groove clamp by staff. The temperature sensor 6 can monitor the temperature in real time and detect overheating problems promptly. When the temperature is below 80℃, the temperature sensor 6 is its original color (transparent); when the temperature is between 80-90℃, it is black; and when the temperature is above 90℃, it is dark black and carbonized.
[0044] Compared with related technologies, the insulating protective cover for live-lined distribution network parallel trench clamps provided by this utility model has the following beneficial effects:
[0045] Through the octagonal opening 4 at the bottom of the first sheath 1 and the second sheath 2, the sheath can be inserted into the cable groove clamp along the cable without disassembling the cable. This eliminates the need for power outages during the installation of traditional protective measures, thus avoiding the impact of power outages on the normal power supply of the distribution network, improving power supply reliability, and reducing inconvenience to industrial production and residents' lives.
[0046] The snap-fit block 53 of the snap-fit assembly 5 snaps into the limiting frame 51, which can make the first sheath 1 and the second sheath 2 securely connected. The elastic force generated by the deformation of the elastic sheet 52 under force can ensure that the two fit tightly together, completely wrapping the parallel groove clamp, effectively blocking interference from external factors such as bird nesting materials, droppings, rodent gnawing, and lightweight hanging objects. At the same time, it can resist the corrosion of metal parts of the parallel groove clamp by corrosive substances such as acid rain and salt spray, and extend its service life.
[0047] The first sheath 1, the second sheath 2, and the temperature measuring element 6 are all made of transparent material, which not only allows staff to directly observe the operating status of the parallel groove clamp, but also does not affect the infrared temperature measurement and other detection work; the temperature measuring element 6 can monitor the temperature of the parallel groove clamp in real time, so that staff can deal with it in time and reduce the risk of line faults.
[0048] Second Embodiment

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0050] Specifically, the second embodiment of this application provides an insulating protective cover for a live-installed distribution network parallel trench clamp, wherein a limiting frame 7 is fixedly installed on the top of both the first sheath 1 and the second sheath 2, an installation frame 8 is provided on the inner side of the limiting frame 7, a warning light 84 is fixedly installed on the top of the installation frame 8, a speaker 83 is fixedly installed on the inner side of the installation frame 8, an installation component 9 is provided on the top of the installation frame 8, and a bird-repelling component 10 is provided on the top of the installation component 9.
[0051] Photovoltaic panels 81 are fixedly installed at both ends of the top of the mounting frame 8, and a storage battery 82 is fixedly installed on the inner side of the mounting frame 8.
[0052] The bird deterrent assembly 10 includes a support rod 101, a fixing block 102, multiple connecting rods 103, multiple air guides 104, and multiple reflectors 105. The fixing block 102 is rotatably connected to the top of the support rod 101. The multiple connecting rods 103 are fixedly installed on the side of the fixing block 102. The multiple air guides 104 are respectively fixedly installed on one end of the multiple connecting rods 103. The multiple reflectors 105 are respectively fixedly installed on the inner side of the multiple air guides 104.
[0053] The mounting assembly 9 includes a threaded ring 91 and a threaded rod 92. The threaded ring 91 is fixedly mounted on the top of the mounting frame 8, and the threaded rod 92 is threadedly connected to the inner side of the threaded ring 91. The top of the threaded rod 92 is fixedly mounted on the bottom of the support rod 101.
[0054] A metal plate 71 is fixedly installed on the bottom of the inner side of the limiting frame 7, and a magnetic plate 85 is fixedly installed on the bottom of the mounting frame 8. The magnetic plate 85 is magnetic to the top of the metal plate 71.
[0055] The photovoltaic panel 81 on top of the mounting frame 8 can convert solar energy into electrical energy and store it in the battery 82 to provide power for electrical components such as warning lights 84 and speakers 83. No additional cables need to be laid, saving energy and offering flexible installation, making it especially suitable for complex outdoor electrical environments.
[0056] The mounting frame 8 is magnetically connected to the metal plate 71 inside the limiting frame 7 via the magnetic plate 85, which facilitates quick installation and disassembly; the bird deterrent assembly 10 is also conveniently installed, disassembled and maintained via the threaded rod 92 of the mounting assembly 9 and the threaded ring 91, which reduces the difficulty of operation and maintenance costs for staff.
[0057] Integrating functions such as bird deterrence, warning, and energy supply, this device not only provides basic protection for parallel trench clamps but also enhances their practicality and ability to ensure line safety, enabling a more comprehensive response to the impact of complex outdoor environments on parallel trench clamps.
[0058] The working principle of the insulating protective cover for the live-lined distribution network parallel trench clamp provided by this utility model is as follows:
[0059] The mounting frame 8 is magnetically connected to the metal plate 71 inside the limiting frame 7 via a magnetic plate 85, facilitating installation and disassembly. The photovoltaic panel 81 generates electricity under sunlight and stores the electrical energy in the battery 82, powering the warning light 84, speaker 83, etc. When in use, the warning light 84 flashes and the speaker 83 emits an alarm sound, which can scare away birds. In the bird deterrent assembly 10, the wind force acts on the wind guide 104, causing the connecting rod 103 and the fixing block 102 to rotate, making the light reflected by the reflector 105 constantly change, thereby scaring away birds. The bird deterrent assembly 10 is connected to the threaded ring 91 via the threaded rod 92 of the mounting assembly 9, which can be easily installed, disassembled, and maintained.
[0060] Compared with related technologies, the insulating protective cover for live-lined distribution network parallel trench clamps provided by this utility model has the following beneficial effects:
[0061] By setting up the bird deterrent component 10, when the wind force acts on the wind deflector 104, it can drive the connecting rod 103 and the fixing block 102 to rotate, so that the light reflected by the reflector 105 changes continuously. Combined with the flashing of the warning light 84 and the alarm sound emitted by the speaker 83, it can drive away birds from multiple dimensions of vision and hearing, effectively reducing the situation of birds nesting near the cable clamp and reducing the risk of line failure caused by bird activity.
[0062] To address the aforementioned problems, this utility model also provides a method for using an insulating protective cover for a live-installed distribution network parallel trench clamp, comprising the following steps:
[0063] S1. Insert the first sheath 1 into the cable on one side of the grooved clamp along the octagonal opening 4, so that the cable passes through the center hole 3, and adjust the position of the first sheath 1 to fit against the side of the grooved clamp.
[0064] S2. In the same way, the second sheath 2 is put into the cable on the other side of the parallel groove clamp, so that the first sheath 1 and the second sheath 2 are relatively close together. The locking block 53 of the locking component 5 is locked into the limiting frame 51 to complete the fixation. After the elastic sheet 52 is deformed by force, it ensures that the two tightly wrap the body of the parallel groove clamp.
[0065] S3. Check the fit between the center hole 3 and the cable, and confirm that the temperature measuring element 6 is facing the direction of direct sunlight.
[0066] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
