Description

Technical Field

[0001] This invention relates to the field of power and communication line protection technology, specifically to a hinged protection device for long-distance secondary cables and optical cables. Background Technology

[0002] OPGW optical cables, as the transmission medium for power signals, undertake the transmission of important services such as protection and dispatch data networks between substations. Their safety and reliability directly affect the effective transmission of various power communication signals. The connection point where the guide optical cable enters the optical cable conduit in the substation structure is a common fault point. Therefore, existing technology has installed a sealing protection device to seal this point. This device includes a hinged outer shell with a rubber liner inside. The rubber liner has holes for the cable to pass through and openings for clamping the end of the conduit. During installation, the end of the conduit is placed in the opening, the cable is placed in the hole, the hinged outer shell is closed, and bolts are used to fix it, thus sealing the connection between the cable and the conduit.

[0003] In the prior art, such as the patent application CN201720897005.8 entitled "A Hinged Optical Cable Sheath Sealing and Protection Device", it consists of a cylindrical shell with an upper end cap and an optical cable liner adhered inside it. The cylindrical shell with the upper end cap is formed by two symmetrically arranged hollow semi-cylindrical shells being bonded together. The outer sides of the bonding surfaces of the two semi-cylindrical shells are hinged together by matching hinges. The other outer side of the bonding surfaces of the two semi-cylindrical shells is provided with a matching wire threaded sleeve structure. Inside the cylindrical shell, there is a fixed optical cable liner made of elastic rubber material with a frustum-shaped upper part and a cylindrical lower part. The lower end of the optical cable liner extends out of the cylindrical shell, and the upper end of the optical cable liner extends out of the hole in the center of the upper end cap of the cylindrical shell.

[0004] This device relies on bolts to keep the hinged outer shell closed and uses a rubber liner to clamp the cable and conduit. Therefore, the connection between the bolt and the outer shell plays a crucial role. Once the bolt loosens, the hinged outer shell will open, and the liner will lose its seal. However, this device is exposed to the elements year-round. In rainy climates, the bolt connection will frequently get wet and damp, accelerating aging and corrosion, causing the bolt to loosen and greatly reducing the device's seal, thus losing its protective effect. To address these issues, a hinged protection device for long-distance secondary cables and optical cables is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a hinged protection device for long-distance secondary cables and optical cables, in order to solve the problem mentioned in the background art that the bolt connection is often exposed to rain and moisture during operation, which accelerates the aging and corrosion, causes the bolts to loosen, greatly reduces the sealing performance of the device, and loses its sealing and protection effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hinged protection device for long-distance secondary cables and optical cables, comprising a body, the body comprising a shell, a first cavity being provided on the inner side of the shell, and a sealing element being provided at the first cavity, a cable hole and a clamping opening being provided through the inner side of the sealing element, the cable hole and the clamping opening being internally connected, and a first connecting seat and a second connecting seat being provided on the outer side of the shell by bolts;

[0007] A protective assembly is provided on the outer side of the housing. The protective assembly includes a protective cover that slides circumferentially along the housing. The inner side of the protective cover has a second cavity for accommodating the first connecting seat, the second connecting seat, and the bolt. During installation, the hinged housing is opened, and the sleeve and cable are placed in the cable hole and clamping port of the sealing element, respectively. Then, the housing is closed, and the first connecting seat and the second connecting seat are connected by bolts to complete the sealing and protection of the connection between the sleeve and the cable. Finally, the protective assembly is operated to cover and protect the bolt connection. With the setting of the protective cover, after the bolts connect the first connecting seat and the second connecting seat, the sliding protective cover can cover the connection to prevent rainwater from directly hitting the connection and reduce the corrosion and aging rate of the connection.

[0008] Preferably, the outer side of the protective cover is evenly distributed with several anti-slip strips, which facilitates the sliding of the protective cover.

[0009] Preferably, the opening of the protective cover is provided with a baffle, and the side of the baffle is provided with a hinge seat.

[0010] Preferably, a torsion spring is provided at the rotatable joint between the protective cover and the baffle, and a rotating shaft is provided on the hinge seat. The torsion spring is located on the outside of the rotating shaft. The torsion spring is used to keep the baffle sealed at the opening of the protective cover, preventing the baffle from opening due to wind or vibration and the protective cover from sliding, thus exposing the connection. Furthermore, when installing bolts, the torsion spring can make the baffle press against the sliding groove of the outer shell, preventing the protective cover and the baffle from easily loosening and affecting the installation of bolts.

[0011] Preferably, the baffle is provided with a guide plate, and a notch is provided on one side of the protective cover. The slider is aligned with the insertion port and inserted to slide into the groove. Finally, the plug is embedded in the insertion port to prevent the slider from easily falling out of the groove. A notch is also provided on the side of the protective cover away from the opening, and the notch is matched with the groove.

[0012] Preferably, the outer side of the outer shell is provided with a sliding groove, and a block is provided at one end of the top of the sliding groove. The sliding groove is a raised structure provided on the outer side of the outer shell, and a groove is provided at the raised structure to prevent the protective cover and baffle from easily loosening and affecting the installation of bolts.

[0013] Preferably, the inner side of the first connecting seat is provided with a through hole, and the inner side of the second connecting seat is provided with a threaded hole. The through hole and the threaded hole can provide an effective connection and limiting function, ensuring stability.

[0014] Preferably, the inner side of the protective cover is provided with a slider, and one end of the slide groove has an insertion port at the top. The slide groove has an insertion port, and the protective cover has a slider on the side near the outer shell. During assembly, simply fit the protective cover to the outer shell, align the slider with the insertion port, and insert it to slide the slider into the slide groove. Finally, insert the plug into the insertion port to prevent the slider from easily detaching from the slide groove. The protective cover also has a notch on the side away from the opening, which fits into the slide groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, by opening the hinged outer shell, placing the sleeve and cable at the cable hole and clamping opening of the sealing component respectively, and then closing the outer shell, the first connecting seat and the second connecting seat are connected by bolts to complete the sealing and protection of the connection between the sleeve and the cable. Finally, the protective component is operated to cover and protect the bolt connection. With the setting of the protective cover, after the bolts connect the first connecting seat and the second connecting seat, the sliding protective cover can cover the connection to prevent rainwater from directly hitting the connection and reduce the corrosion and aging rate of the connection.

[0017] 2. In this invention, the anti-slip strip facilitates the sliding of the protective cover, and the torsion spring keeps the baffle sealed at the opening of the protective cover, preventing the baffle from opening due to wind or vibration and the protective cover from sliding, thus exposing the connection. Furthermore, when installing bolts, the torsion spring can press the baffle against the groove of the outer shell, preventing the protective cover and baffle from easily loosening and affecting the installation of bolts.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: As Figures 1-6 As shown, the present invention provides a technical solution: a hinged protection device for long-distance secondary cables and optical cables, including a body 100, characterized in that: the body 100 includes a shell 110, a first cavity is provided on the inner side of the shell 110, and a sealing member 120 is provided at the first cavity, a cable hole 221 and a clamping port 522 are provided through the inner side of the sealing member 120, the cable hole 221 and the clamping port 522 are connected internally, and a first connecting seat 311 and a second connecting seat 312 are provided on the outer side of the shell 110 by bolts 313;

[0028] A protective assembly 130 is provided on the outer side of the housing 110. The protective assembly 130 includes a protective cover 231 that slides circumferentially along the housing 110. The inner side of the protective cover 231 has a second cavity for accommodating the first connecting seat 311, the second connecting seat 312, and the bolt 313.

[0029] In this embodiment, during installation, the hinged outer shell 110 is opened, and the sleeve and cable are placed at the cable hole 221 and clamping port 522 of the sealing component 120, respectively. Then, the outer shell is closed, and the first connecting seat 311 and the second connecting seat 312 are connected by bolts 313 to complete the sealing and protection of the connection between the sleeve and the cable. Finally, the protective component 130 is operated to cover and protect the connection of bolts 313. With the setting of the protective cover 231, after the bolts 313 connect the first connecting seat 311 and the second connecting seat 312, the sliding protective cover 231 can cover the connection to prevent rainwater from directly hitting the connection and reduce the corrosion and aging rate of the connection.

[0030] Example 2: Figures 1-2 As shown, a number of anti-slip strips 236 are evenly distributed on the outer side of the protective cover 231. A baffle 232 is provided at the opening of the protective cover 231. A hinge seat 235 is provided on the side of the baffle 232. A torsion spring 233 is provided at the rotational engagement point between the protective cover 231 and the baffle 232. A rotating shaft 234 is provided on the hinge seat 235. The torsion spring 233 is located on the outer side of the rotating shaft 234.

[0031] In this embodiment, the anti-slip strip 236 facilitates the sliding of the protective cover 236, and the torsion spring 233 keeps the baffle 232 sealed at the opening of the protective cover 231, preventing wind or vibration from opening the baffle 232 and causing the protective cover 231 to slide and expose the connection. Furthermore, when installing the bolt 313, the torsion spring 233 can press the baffle 232 against the groove 336 of the outer shell 110. The groove 336 is a raised structure on the outside of the outer shell 110, and the groove is provided at the raised structure to prevent the protective cover 231 and the baffle 232 from easily loosening and affecting the installation of the bolt 313.

[0032] Example 3: As Figures 3-6 As shown, a guide plate 3320 is provided on the baffle 232, a notch 6311 is provided on one side of the protective cover 231, a sliding groove 336 is provided on the outer side of the outer shell 110, a block 437 is provided at one end of the top of the sliding groove 336, a through hole 5110 is provided on the inner side of the first connecting seat 311, a threaded hole 5120 is provided on the inner side of the second connecting seat 312, a slider 6310 is provided on the inner side of the protective cover 231, and an insertion port 6360 is provided at the top of one end of the sliding groove 336.

[0033] In this embodiment, during operation, simply sliding the protective cover 231 causes the guide plate 3320 to initially contact the bolt 313. Continuing to slide the protective cover 231 causes the inclined surface of the guide plate 3320 to rub against the bolt 313, automatically flipping the guide plate 3320 and the baffle 232. Simultaneously, the torsion spring 233 automatically twists. As the protective cover 231 continues to slide until the guide plate 3320 and the baffle 232 pass the bolt 313 connection, the torsion spring 233 returns to its original position, flipping the baffle 232 to seal the opening of the outer casing 110. The bolt 313 and the connection are not exposed, making it difficult for air and rainwater to enter and corrode it. The guide plate 3320 can also be moved while the protective cover 231 is sliding. The baffle 232 is automatically flipped. Without the guide plate 3320, after the bolt 313 is installed, the protective cover 231 will slide and cause the baffle 232 to press against the bolt 313. At this time, it cannot slide and the baffle 232 must be manually flipped over to pass the connection. After the protective cover 231 completely covers the connection, the baffle 232 can be released to seal the opening of the protective cover 231. When the guide plate 3320 is set, the inclined surface of the guide plate 3320 can contact the bolt 313, and the guide plate 3320 flips and drives the baffle 232 to flip, so that the protective cover 231 can automatically seal the opening of the connection after sliding and covering it, without manual operation.

[0034] In this invention, when using the hinged protection device for long-distance secondary cables and optical cables, the first step during installation is to open the hinged outer casing 110, place the sleeve and cable respectively at the cable hole 221 and clamping opening 522 of the sealing component 120, then close the outer casing, and connect the first connecting seat 311 and the second connecting seat 312 with bolts 313 to complete the sealing and protection at the connection between the sleeve and the cable. At this time, the device is... Figure 6 The state shown is as follows; finally, operate the protective component 130 to cover and protect the bolt 313 connection; during operation, simply slide the protective cover 231, and the guide plate 3320 will first contact the bolt 313. Continuing to slide the protective cover 231 will cause the inclined surface of the guide plate 3320 to rub and slide against the bolt 313, causing the guide plate 3320 and the baffle 232 to automatically flip over, and at the same time automatically twist the torsion spring 233. Continue to slide the protective cover 231 until the guide plate 3320 and the baffle 232 pass the bolt 313 connection, and the torsion spring 233 returns to its original state, flipping the baffle 232 to seal the opening of the outer casing 110. At this time, the device is... Figure 5As shown, bolts 313 and the connection are not exposed, making it difficult for air and rainwater to enter and corrode them. When assembling the protective cover 231, a socket 6360 is provided at the slide groove 336, and a slider 6310 is provided on the side of the protective cover 231 near the outer shell 110. During assembly, simply fit the protective cover 231 against the outer shell 110, align the slider 6310 with the socket 6360, and insert it to slide the slider 6310 into the slide groove 336. Finally, the plug 437 is embedded in the socket 6360 to prevent the slider 6310 from easily dislodging from the slide groove 336. A notch 6311 is also provided on the side of the protective cover 231 away from the opening, and the notch 6311 mates with the slide groove 336.
