Description

Technical Field

[0002] In the field of power cables, moisture intrusion can lead to conductor corrosion, decreased insulation performance, and even serious faults such as short circuits, affecting the conductor's power transmission performance and service life.

[0003] Therefore, most power cable projects currently require water-blocking conductors. One common method for water-blocking conductors is to install longitudinal water-blocking strips on or inside the conductor to prevent water from penetrating longitudinally along the conductor.

[0004] However, because the water-blocking tape has a very strong moisture absorption capacity, especially in the plum rain season or in humid environments, the water-blocking tape will not only lose its water-blocking performance after absorbing moisture, but it will also turn yellow, affecting both the water-blocking performance and the product's appearance.

[0055] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0057] In the field of power cables, moisture intrusion can lead to conductor corrosion, decreased insulation performance, and even serious faults such as short circuits, affecting the conductor's power transmission performance and service life.

[0058] Therefore, most power cable projects currently require water-blocking conductors. One common method for water-blocking conductors is to install longitudinal water-blocking strips on or inside the conductor to prevent water from penetrating longitudinally along the conductor.

[0059] However, because the water-blocking tape has a very strong moisture absorption capacity, especially in the plum rain season or in humid environments, the water-blocking tape will not only lose its water-blocking performance after absorbing moisture, but it will also turn yellow, affecting both the water-blocking performance and the product's appearance.

[0060] To address the aforementioned technical problems, this application proposes a moisture-proof device for water-blocking tape. By drying the water-blocking tape, the device prevents the tape from getting damp during use, thereby avoiding the impact of moisture on the water-blocking performance and aesthetics of the tape.

[0061] The technical solution of the water-blocking tape moisture-proof device provided in this application will be described in detail below through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and the same or similar content may not be described again in different embodiments.

[0062] Figure 1 and Figure 2 This is a schematic diagram of a water-blocking tape moisture-proof device provided in an embodiment of this application. (See attached diagram.) Figure 1 and Figure 2In some embodiments, the water-blocking tape moisture-proof device includes a protective box 100, a tape-releasing device 300, and a heating and drying device 200; the tape-releasing device 300 is disposed inside the protective box 100 and is used to install and release the water-blocking tape; a tape-releasing port 105 for the water-blocking tape to pass through is provided on one side of the protective box 100; the heating and drying device 200 is used to heat and dry the inside of the protective box 100 to prevent the water-blocking tape from getting damp.

[0063] In this embodiment, by installing the water-blocking tape on the tape-releasing device 300 located inside the protective box 100, and by heating and drying the inside of the protective box 100 through the heating and drying device 200, the water-blocking tape inside the protective box 100 is effectively prevented from getting damp without affecting the normal use of the water-blocking tape, so that the water-blocking tape can maintain good water-blocking performance and aesthetics.

[0064] See Figure 1 Optionally, the protective box 100 includes a box body 101, and a closable door 102 is provided on one side of the box body 101.

[0065] The closable door 102 allows for easy viewing of the interior of the protective box 100, facilitating the inspection and maintenance of the internal tape feeding device 300 and the replacement of used water-blocking rolls.

[0066] Specifically, the cabinet body 101 on one side of the door 102 is hinged together by a hinge 104 or other hinges to facilitate the opening and closing of the door 102. A door lock 103 can also be installed on the door 102 to prevent the door 102 from being accidentally opened during the use of the water-blocking and moisture-proof device, which would affect the drying effect.

[0067] Specifically, the door 102 can be made of transparent materials such as plexiglass or plastic, which makes it easy to observe the contents of the protective box 100 from the door 102.

[0068] Optionally, multiple casters can be installed at the bottom of the housing 101, which can facilitate moving the protective housing 100 to different working positions.

[0069] See Figure 3 In some embodiments, the tape-laying device 300 includes a mounting frame with a rotatable tape-laying turntable for mounting water-blocking tape.

[0070] In this embodiment, the mounting frame is used to install the tape feeding tray, and the tape feeding turntable is used to install the water-blocking tape. After the water-blocking tape is installed on the tape feeding turntable, the tape feeding turntable can facilitate the tape feeding operation of the water-blocking tape in the subsequent tape feeding process, reduce the labor intensity of the tape feeding operation, and ensure the smooth feeding of the water-blocking tape.

[0071] See Figure 3 Optionally, the tape-laying turntable includes a rotating shaft 305, a first baffle 302, and a second baffle 303; the rotating shaft 305 is rotatably connected to the mounting bracket; the first baffle 302 and the second baffle 303 are spaced apart and mounted on the rotating shaft 305, and the first baffle 302 and the second baffle 303 are used to clamp and install the water-blocking tape.

[0072] Since water-blocking tape is typically packaged in rolls at the factory, and these rolls usually contain a core that supports and maintains the roll shape, the outer baffle is removed during installation. The core of the water-blocking tape is then inserted into the shaft 305, and the baffle is reinstalled, thus installing the water-blocking tape between the first baffle 302 and the second baffle 303.

[0073] The water-blocking tape is then pulled out from the unwinding port on the protective box 100. During this pulling process, the unwinding turntable rotates, enabling the unwinding operation of the water-blocking tape. During unwinding, the first baffle 302 and the second baffle 303 limit and guide the water-blocking tape, maintaining its unwinding direction. The first baffle 302 and the second baffle 303 also prevent the water-blocking tape from becoming tangled during unwinding.

[0074] Specifically, the shaft 305 and the mounting bracket are rotatably connected by a bearing, which can reduce friction and wear, and enhance load-bearing capacity and stability.

[0075] See Figure 4 Optionally, the rotating shaft 305 is provided with a first lock nut 309 and a second lock nut 304; the first lock nut 309 is used to position and install the first baffle 302; the second lock nut 304 is used to position and install the second baffle 303.

[0076] Among them, the lock nut is a special type of nut. After reaching the predetermined position on the rotating shaft 305, the lock nut fixes itself on the rotating shaft 305 and is fixedly connected to the baffle, so that the baffle is installed at the predetermined position on the rotating shaft 305 to play a reliable fixing role.

[0077] Specifically, the lock nut is fixedly connected to the rotating shaft 305 and the baffle by screws.

[0078] See Figure 4 Optionally, one end of the rotating shaft 305 passes through the mounting bracket and is fitted with a drive wheel 301, which is used to connect to the drive mechanism.

[0079] Specifically, by installing a drive wheel 301 at one end of the rotating shaft 305 and connecting the drive wheel 301 to the drive mechanism, the drive mechanism drives the drive wheel 301 to rotate, which in turn drives the rotating shaft 305 to rotate. The rotating shaft 305 further drives the water-blocking belt installed on the belt feeding turntable to rotate, thereby realizing the automatic feeding of the water-blocking belt, improving the feeding efficiency of the water-blocking belt, and reducing the labor intensity of feeding the water-blocking belt.

[0080] Specifically, the drive mechanism is a drive motor, and the drive wheel 301 is connected to the drive motor via a belt or chain, thereby using the drive motor to drive the belt or chain to rotate the drive wheel 301.

[0081] See Figure 3 Optionally, the mounting bracket includes a base 306 and a stand 308; the base 306 is fixedly connected to the bottom of the protective box 100; the stand 308 is fixedly mounted on the base 306.

[0082] The mounting bracket is stably installed at the bottom of the protective box 100 via the base 306, and the upright 308 provides an installation position for the mounting rollers.

[0083] Specifically, the base 306 and the protective box 100 are fixedly connected by bolts, so that the base 306 and the protective box 100 have a detachable connection structure, which facilitates the disassembly and maintenance of the mounting bracket in the future.

[0084] Specifically, the base 306 and the upright 308 are welded and fixed together to ensure the firmness of the connection between the base 306 and the upright 308.

[0085] See Figure 3 Optionally, multiple reinforcing support plates 307 are provided between the stand 308 and the base 306.

[0086] Among them, multiple reinforcing support plates 307 are set between the upright 308 and the base 306 to ensure the stability of the upright 308 installed on the base 306.

[0087] Specifically, the reinforcing support plate 307 is a right-angle plate, with one right-angled side fixedly connected to the upright frame 308 and the other right-angled side fixedly connected to the base 306. The right-angle plate is welded and fixed to the upright frame 308 and the base 306.

[0088] See Figure 1 In some embodiments, the heating and drying device 200 includes a fan 201 and a drying gun 203; the fan 201 is connected to the air inlet of the drying gun 203 through an air duct 202; the nozzle of the drying gun 203 is connected to the inner cavity of the protective box 100.

[0089] In this embodiment, the main structural components of the fan 201 include an impeller, casing, air inlet, support, and motor. The fan 201 converts mechanical energy into the pressure and kinetic energy of the gas through the rotation of the impeller, thereby achieving gas transport and discharge. The core component of the drying gun 203 is a heating element, such as a heating wire or heating tube. The heating element generates heat energy by energizing it, converting electrical energy into heat energy, and transferring it to the surrounding air. The heated air is drawn into the drying gun 203 and sprayed into the protective box 100 through the nozzle to heat and dry the water-blocking strip inside the protective box 100.

[0090] By using the fan 201 in conjunction with the drying gun 203, the fan 201 helps to diffuse the hot air, avoid localized overheating, and improve overall drying uniformity. At the same time, the diffusion of hot air by the fan 201 also increases the area covered by the hot air, thereby improving drying efficiency.

[0091] Optionally, a filter screen is provided at the nozzle of the drying gun 203.

[0092] Among them, by setting a filter screen at the nozzle of the drying gun 203, the filter screen can intercept dust, particles or impurities in the air and prevent them from entering the protective box 100 and contaminating the water-blocking belt, so as to keep the water-blocking belt clean.

[0093] Optionally, a temperature sensor can also be installed inside the protective box 100 to collect the temperature inside the protective box 100, thereby adjusting the power of the drying gun 203 according to the temperature inside the protective box 100 to avoid the temperature inside the protective box 100 being too high or too low.
