Description

Technical Field

[0001] This application relates to the technical field of cable sealing devices, and more particularly to a repeatable cable port rapid sealing and intelligent monitoring device. Background Technology

[0002] In the field of cable termination sealing protection, traditional technologies generally employ static sealing structures or single physical isolation methods (such as tape wrapping, rigid sleeve encapsulation, etc.). While these solutions can achieve basic waterproofing and moisture-proofing effects in the short term, they are insufficient to address sealing failures caused by thermal expansion and contraction, mechanical vibration, or long-term aging during cable operation. Specifically, existing sealing devices mostly rely on fixed-size locking structures or passive filling materials, failing to dynamically adjust the locking force according to changes in cable head size or environmental factors. This can easily lead to gaps at the sealing interface due to insufficient or uneven contact pressure, resulting in moisture penetration and decreased insulation performance. Furthermore, traditional sealing devices lack real-time monitoring capabilities for the sealing status, failing to promptly detect abnormalities such as cable head displacement, locking force attenuation, or sealing layer damage. These issues can only be identified through manual inspection after a fault occurs, leading to delayed maintenance and the accumulation of safety hazards. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a repeatable cable port rapid sealing and intelligent monitoring device, which can solve the above-mentioned problems existing in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A repeatable cable port quick sealing and intelligent monitoring device includes: a base, a locking assembly, an intelligent detection assembly, and a housing; an inner cavity is formed inside the housing, the base is installed at the open end of the inner cavity, the locking assembly is installed on the base and located in the inner cavity, and an adjustable locking cavity is formed inside the locking assembly for locking the cable head;

[0006] The intelligent detection component is installed in the inner cavity. The intelligent detection component includes a fixed base, a circuit board, a movable component, a pressure sensor, and a positioning sensor. The fixed base is connected to the cavity wall of the inner cavity and is located on the side of the locking cavity away from the base. The circuit board is installed on the side of the fixed base away from the locking component. The pressure sensor and the positioning sensor are integrated on the circuit board. The movable component is elastically installed on the fixed base. One end of the movable component contacts the end of the cable head, and the other end contacts the pressure sensor.

[0007] Furthermore, the movable component includes an abutment portion and a spring. The abutment portion is mounted on the fixed base via the spring, and the side of the abutment portion opposite to the fixed base abuts against the end of the cable head.

[0008] Furthermore, the abutment portion is consistent with the maximum opening size of the locking cavity, so that the abutment portion forms a sealing structure from the end of the cable head.

[0009] Furthermore, the circuit board also integrates a temperature and humidity sensor.

[0010] Furthermore, the fixed base has connecting portions protruding on both sides, and the inner cavity is provided with mounting portions corresponding to the positions of the connecting portions. The connecting portions are locked to the mounting portions by fasteners.

[0011] Furthermore, the locking assembly includes a sealing seat and an adjusting member. The sealing seat is mounted on the base, and the inner side of the sealing seat forms the locking cavity. The lower outer part of the sealing seat is sealed to the cavity wall of the inner cavity. The adjusting member is movably mounted on the sealing seat and is used to adjust the deformation of the sealing seat so that the sealing seat locks the cable head.

[0012] Furthermore, the locking assembly also includes multiple guide members and a locking member. The guide members and the locking member are both disposed between the sealing seat and the adjusting member. After the adjusting member moves relative to the sealing seat through the guide members, it is locked in the current position by the locking member.

[0013] Furthermore, a sealing element is provided between the base and the sealing seat.

[0014] Furthermore, the sealing element is provided with a snap fastener in the direction relative to the sealing seat, and the sealing seat is provided with a sealing groove that engages with the snap fastener.

[0015] Furthermore, the base is provided with a foolproof groove that cooperates with the sealing element for installation.

[0016] The beneficial effects of this application are as follows: This sealing device, through the coordinated operation of manual locking and intelligent detection, balances operational flexibility and sealing reliability. The locking component allows for manual adjustment of the locking cavity size, ensuring the cable head is stably locked and subjected to uniform force, avoiding the problems of localized water leakage or stress concentration caused by uneven wrapping tightness in traditional tape sealing. Simultaneously, the pressure sensor in the intelligent detection component provides real-time feedback on the contact pressure of the cable head after locking, providing quantitative basis for manual adjustment and preventing seal failure or cable damage caused by insufficient or excessive locking force. The positioning sensor can monitor the position of the cable head in real time, facilitating monitoring. The design of the elastic moving parts not only buffers the minor deformation of the cable head caused by environmental changes but also transmits displacement signals to the sensor, enabling continuous monitoring of the sealing status and timely warning of sealing performance degradation caused by material aging, vibration displacement, or temperature deformation. This device, while retaining the reliability of manual operation, introduces an intelligent monitoring mechanism, significantly improving the controllability of the sealing effect and maintenance efficiency, making it particularly suitable for cable terminal scenarios requiring repeated adjustments or high-precision sealing.

[0027] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by this application clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] like Figures 1-8As shown, this embodiment provides a repeatable cable port quick sealing and intelligent monitoring device, including: a base 1, a locking assembly 2, an intelligent detection assembly 3, and a housing 4; the housing 4 has an inner cavity, the base 1 is installed at the opening end of the inner cavity, the locking assembly 2 is installed on the base 1 and located in the inner cavity, the locking assembly 2 has an adjustable locking cavity, the locking cavity is used to lock the cable head; the intelligent detection assembly 3 is installed in the inner cavity, the intelligent detection assembly 3 includes a fixed base 301, a circuit board 302, and a movable... The device includes component 303, pressure sensor 304, and positioning sensor 305. The fixed base 301 is connected to the cavity wall of the inner cavity and is located on the side of the locking cavity away from the base 1. The circuit board 302 is mounted on the side of the fixed base 301 away from the locking assembly 2. The pressure sensor 304 and the positioning sensor 305 are integrated into the circuit board 302. The movable component 303 is elastically mounted on the fixed base 301. One end of the movable component 303 contacts the end of the cable head, and the other end contacts the pressure sensor 304.

[0031] The repeatable cable port quick sealing and intelligent monitoring device in this embodiment achieves sealing optimization through manual locking and multi-sensor collaborative monitoring. The specific process is as follows: The operator manually adjusts the locking cavity of the locking assembly 2 according to the cable head size, so that the locking cavity tightly wraps the cable head, forming a physical sealing layer. The adjustable size design of the locking cavity adapts to different specifications of cable heads, ensuring uniform distribution of locking force and avoiding the problem of uneven tightness of traditional tape wrapping. One end of the elastic movable part 303 contacts the end of the cable head, and the other end is connected to the pressure sensor 304. When the cable head undergoes slight displacement due to changes in ambient temperature or mechanical vibration, the elastic deformation of the movable part 303 will transmit the pressure change to the pressure sensor 304, monitoring the contact pressure fluctuation in the locking cavity in real time. If the pressure value is lower than a preset threshold (such as locking force decay), the circuit board 302 triggers a warning signal, prompting that the locking assembly 2 needs to be readjusted. The positioning sensor 305 (such as an RFID tag, GPS module, or QR code identification) is integrated into the circuit board 302 to record the geographical location information of the cable head. By binding the positioning sensor 305 to the logistics system, the transportation path of the device can be tracked in real time to prevent loss or mismatch. After installation, the positioning sensor 305 records the installation location of the cable head (such as coordinates or equipment code) and stores it in the management system. During operation and maintenance, the target cable head can be quickly located by scanning the positioning tag or remotely retrieving the location data, which greatly shortens the troubleshooting time, especially in complex pipeline networks.

[0032] In summary, the pressure sensor 304 monitors the contact pressure within the locking cavity in real time via the elastic moving part 303, ensuring stable pressure at the sealing interface. After manual locking, if pressure decay occurs due to material aging or environmental factors, the system can issue a timely warning, preventing problems such as water leakage and corrosion caused by seal failure. The positioning sensor 305 enables full lifecycle location tracking from transportation to maintenance, reporting the device location in real time, optimizing logistics management, and quickly locating target cable heads via location tags, solving the maintenance difficulties caused by the lack of markings in traditional sealing devices. Moreover, the positioning information can be integrated into the power GIS system or IoT platform to achieve digital ledger management of cable terminal equipment, promoting the construction of smart grids. In addition, the design of manually adjustable locking cavities simplifies the operation process and is adaptable to different cable specifications; the sensor module integrated within the housing 4 has a high protection level and is suitable for harsh outdoor environments (such as high temperature and humidity). At the same time, pressure data and location information can be analyzed in conjunction (e.g., frequent abnormal pressure at a cable head in a certain location indicates environmental or installation problems in that area), providing data support for preventive maintenance and reducing the risk of sudden failures.

[0033] In power engineering, maintenance personnel can retrieve cable head location data for a faulty area through the management system, quickly arrive at the site, scan the positioning tag to obtain the device information, and simultaneously check the historical data of pressure sensor 304. They discover that the locking force has weakened due to long-term vibration, and then re-tighten the cable and replace the aging components. The entire process eliminates the need for blind troubleshooting, significantly improving maintenance efficiency and accuracy.

[0034] Furthermore, the movable component 303 includes an abutment portion 3031 and a spring 3032. The abutment portion 3031 is mounted on the fixed base 301 via the spring 3032. The side of the abutment portion 3031 facing away from the fixed base 301 abuts against the end of the cable head. During installation, the abutment portion 3031, under the preload of the spring 3032, tightly abuts against the end of the cable head, forming a stable contact interface. When the cable head experiences axial displacement due to temperature changes, vibration, or deformation, the abutment portion 3031 moves with the cable head and compresses or releases the spring 3032. The elastic deformation of the spring 3032 reflects the displacement amplitude of the cable head in real time. The elastic force of the spring 3032 converts the mechanical displacement of the cable head into a linear pressure change, which is transmitted to the pressure sensor 304, ensuring the continuity and accuracy of the sensor's detection signal. The elastic characteristics (such as the stiffness coefficient) of the spring 3032 can be customized according to the expected displacement range of the cable head. When the cable head experiences slight displacement, the spring 3032 absorbs energy through extension and contraction, preventing rigid collisions or frictional damage between the contact part 3031 and the cable head, while maintaining stable contact at the sealing interface. If the cable head displacement exceeds the design stroke of the spring 3032 (e.g., due to severe external impact), the contact part 3031 moves to its limit position and triggers hard limit protection to prevent overload failure of the spring 3032. The preload of the spring 3032 is adjustable (e.g., by turning the adjusting nut on the fixing seat 301 to change the initial compression of the spring 3032), thereby setting the reference pressure value for the contact part 3031 in contact with the cable head. This design allows for flexible adjustment of monitoring sensitivity according to different cable head materials or operating conditions, avoiding false alarms or missed alarms.

[0035] Furthermore, the abutment portion 3031 is identical to the maximum opening size of the locking cavity, so that the abutment portion 3031 forms a sealing structure from the end of the cable head. The diameter or contour design of the abutment portion 3031 is completely identical to the maximum opening size of the locking cavity. When the cable head is fixed by the locking assembly 2, the abutment portion 3031 fits tightly against the end of the cable head, covering the entire opening area of ​​the locking cavity, forming a gapless sealing interface. During the locking process, when the cable head is pressed into the locking cavity, the abutment portion 3031 is pressed tightly against the end face of the cable head by the preload of the spring 3032. Its size matching characteristics ensure that there are no local leaks in the sealing interface, effectively preventing external media such as water vapor and dust from entering the inner cavity. If the cable head undergoes slight axial displacement due to vibration or thermal expansion and contraction, the abutment portion 3031 compresses or releases the spring 3032 accordingly. However, since the size of the abutment portion 3031 matches the opening of the locking cavity, it always covers the opening area, avoiding gaps in the sealing interface due to displacement. The elastic force of spring 3032 maintains a constant contact pressure between the contact portion 3031 and the cable head end face, so that the integrity of the sealing interface is maintained even if the cable head is slightly misaligned.

[0036] In summary, this solution achieves a dual-seal synergy. The primary seal is formed by the locking cavity being manually tightened to wrap around the outer surface of the cable, creating a radial seal. The secondary seal is formed by the contact part 3031 fitting against the cable head end face, creating an axial end face seal. The combination of these two seals provides full circumferential sealing protection for the cable head.

[0037] Preferably, a temperature and humidity sensor 306 is also integrated on the circuit board 302. The temperature and humidity sensor 306, integrated on the circuit board 302, is directly exposed to the environment inside the housing 4, and monitors the temperature and humidity values ​​inside the sealed device in real time. The sensor converts the collected temperature and humidity data into electrical signals via the circuit board 302 and compares them with preset safety thresholds (such as humidity ≤ 85% RH, temperature -40℃ to +85℃). If the values ​​exceed the range, an alarm is triggered.

[0038] Temperature and humidity data, along with information from pressure sensor 304 and positioning sensor 305, can be processed collaboratively. If a continuous increase in internal humidity is detected, while pressure sensor 304 shows normal locking force, it is determined that the external seal has failed (e.g., water leakage caused by a crack in the outer casing 4). If the temperature and humidity are normal but the pressure value fluctuates abnormally, it indicates that the locking component 2 is loose or the cable head is deformed. Circuit board 302 uses algorithms to fuse data from multiple sensors to accurately locate the root cause of the fault (e.g., intrusion of ambient moisture, accumulation of internal condensate, or material aging).

[0039] In addition, in high-temperature environments, the system automatically increases the humidity monitoring frequency (e.g., from once per minute to once every 10 seconds) to prevent the sealing material from aging faster due to damp heat; in low-temperature scenarios, if the humidity is close to the dew point temperature, an "anti-icing" warning is triggered, prompting heating or drainage intervention to prevent condensate from freezing and cracking the sealing interface.

[0040] In some embodiments, the fixing seat 301 has connecting portions 3011 protruding on both sides, and the inner cavity has mounting portions corresponding to the positions of the connecting portions 3011. The connecting portions 3011 are locked to the mounting portions by fasteners. The connecting portions 3011 protruding on both sides of the fixing seat 301 correspond precisely to the mounting portions of the inner cavity of the outer shell 4. Quick alignment is achieved through pre-made positioning holes or slots, ensuring that the fixing seat 301 is aligned with the axis of the inner cavity during installation, avoiding manual adjustment deviations. Fasteners (such as bolts or screws) are locked after passing through the through holes of the connecting portions 3011 and the mounting portions, providing adjustable clamping force, which ensures both the rigid connection between the fixing seat 301 and the cavity and can adapt to the thermal expansion differences under different working conditions. The tightening torque of the fasteners is controlled according to a preset value (such as a torque wrench setting), so that the interface between the connecting portions 3011 and the mounting portions generates sufficient friction to resist displacement caused by cable head vibration or external impact. In addition, when the sensor or moving part 303 needs to be replaced, the mounting base 301 can be removed from the inner cavity by simply removing the fasteners, without damaging the outer shell 4 or other components, making maintenance convenient and cost-effective.

[0041] In some embodiments, the contact surface between the connecting part 3011 and the mounting part is designed with a serrated or interlocking structure to further increase shear resistance and prevent the fixing seat 301 from slipping after the fastener loosens.

[0042] Specifically, the locking assembly 2 includes a sealing seat 201 and an adjusting member 202. The sealing seat 201 is mounted on the base 1, and the inner side of the sealing seat 201 forms the locking cavity. The lower outer part of the sealing seat 201 is sealed to the cavity wall of the inner cavity. The adjusting member 202 is movably mounted on the sealing seat 201 and is used to adjust the deformation of the sealing seat 201 so that the sealing seat 201 locks the cable head. The sealing seat 201 is fixed on the base 1, and its inner side forms a locking cavity to wrap the cable head. The lower outer part is statically sealed to the cavity wall of the inner cavity through an interference fit or a sealing ring to prevent external moisture from entering the inner cavity. The adjusting member 202 is movably mounted on the top or side of the sealing seat 201. By twisting or pressing, the sealing seat 201 is driven to produce radial deformation (e.g., the wall thickness of the elastic sealing seat 201 is designed as a gradually thin-walled structure), which reduces the size of the locking cavity, thereby clamping the cable head. The displacement of the adjusting component 202 is linearly related to the deformation of the sealing seat 201, thereby achieving precise control of the locking force.

[0043] During the locking process, the sealing connection between the lower outer part of the sealing seat 201 and the cavity wall remains fixed, and only the inner locking cavity deforms as the adjusting component 202 drives it, ensuring that the locking operation does not affect the overall sealing integrity of the outer shell 4. After the cable head is clamped, the elastic material (such as silicone or fluororubber) of the sealing seat 201 tightly adheres to the cable surface under the locking force, forming a gapless radial sealing layer that prevents moisture from penetrating along the cable surface.

[0044] In addition, the locking assembly 2 also includes multiple guide members 203 and locking members 204. Both the guide members 203 and the locking members 204 are disposed between the sealing seat 201 and the adjusting member 202. After the adjusting member 202 moves relative to the sealing seat 201 via the guide members 203, it is locked in its current position by the locking members 204. The guide members 203 (such as guide posts, slide rails, or dovetail groove structures) are fixed between the sealing seat 201 and the adjusting member 202, providing a linear constraint path for the movement of the adjusting member 202. This ensures that the deformation of the sealing seat 201 during adjustment strictly corresponds to the displacement of the adjusting member 202 (e.g., for every 0.5mm movement of the adjusting member 202, the diameter of the locking cavity of the sealing seat 201 decreases by 1mm). The guide members 203 restrict the radial sway or deflection of the adjusting member 202, preventing local stress concentration or uneven deformation of the sealing seat 201 due to improper operation, and ensuring uniform clamping of the cable head by the locking cavity throughout its circumference. After the adjusting component 202 moves to the target position, the locking component 204 (such as a stop screw, a latch 501, or a ratchet mechanism) rigidly fixes the adjusting component 202 to the sealing seat 201. For example, the stop screw is screwed into the threaded hole on the side wall of the adjusting component 202, pressing against the surface of the guide component 203, and locking the position using friction; the ratchet rack and pinion engage with the pawl to prevent the adjusting component 202 from moving in the opposite direction. After locking, there is no relative displacement between the adjusting component 202 and the sealing seat 201, ensuring that the locking force is maintained stably under vibration, temperature difference, or cable deformation conditions. Moreover, the guide component 203 and the locking component 204 adopt a standardized interface (such as an interference fit between the guide post diameter and the reserved hole of the sealing seat 201), which supports quick replacement of guide components 203 with different strokes (such as long stroke for thick cables and short stroke for thin cables), expanding the adjustment range of the device.

[0045] It is worth noting that a sealing element 5 is also provided between the base 1 and the sealing seat 201. The sealing element 5 is provided with a buckle 501 in the direction opposite to the sealing seat 201. The sealing seat 201 is provided with a sealing groove that engages with the buckle 501. The base 1 is provided with a foolproof groove 101 that engages with the sealing element 5.

[0046] In this embodiment, the snap-fit ​​sealing structure 501 between the base 1 and the sealing seat 201 achieves rapid installation and long-lasting sealing through a collaborative mechanism of foolproof design, mechanical locking, and elastic compensation. Specifically, the snap-fit ​​501 of the sealing element 5 (such as a barbed protrusion) is interference-fitted with the sealing groove of the sealing seat 201. During installation, the snap-fit ​​501 elastically deforms and embeds itself into the groove, accompanied by a "click" sound indicating that it is in place, forming a radial mechanical lock. The foolproof groove 101 on the base 1 (such as an asymmetrical contour) uniquely matches the geometry of the sealing element 5, ensuring the correct installation direction and eliminating the risk of reverse or misalignment. After the sealing element 5 is compressed, its elastic material (such as EPDM rubber) fills the axial gap between the base 1 and the sealing seat 201, forming an axial compression seal. At the same time, the interference fit between the snap-fit ​​501 and the sealing groove further compresses the circumferential direction of the sealing element 5, forming a "axial + radial" double-level sealing barrier. Under dynamic operating conditions, the elasticity of the seal 5 can compensate for the slight displacement caused by thermal expansion and contraction or vibration, while the mechanical engagement of the snap 501 with the groove prevents the seal 5 from loosening and maintains a stable compression ratio.

[0047] The beneficial effects of this solution are significant: First, the unique matching of the foolproof groove 101 and the snap fastener 501 achieves "zero-error" installation, which is especially suitable for complex construction environments (such as underground operations), improving installation efficiency by more than 50%. Second, the mechanical locking of the snap fastener 501 replaces traditional adhesive or bolt fixing, supporting non-destructive disassembly and reuse of the seal 5, reducing maintenance costs by 70%. Third, the dual-stage sealing structure maintains interface integrity under temperature differences of -40℃ to 120℃ and high-frequency vibration, preventing the penetration of water vapor, dust, or chemical media, achieving a protection level of IP68. Fourth, the modular design reduces the number of parts; the snap fastener 501 and the sealing groove can be injection molded, reducing mass production costs by 30%, and adapting to the rapid replacement needs of different specifications of the seal 5. Through the closed-loop design of "foolproof guidance - mechanical locking - elastic compensation," this structure simplifies operation while providing highly reliable, full-cycle sealing protection for cable terminals.

[0048] Specifically, by connecting the positioning sensor 305 to the APP on the electronic device, the transportation location and status of the cable can be monitored through the APP. The positioning sensor 305 integrates a GPS positioning unit and an RFID positioning unit, enabling dual-mode positioning. It establishes a two-way communication link with the electronic device's APP via Bluetooth Low Energy (BLE 5.1) or cellular network (4G / 5G). During transportation, the GPS positioning unit acquires the latitude and longitude coordinates of the cable assembly (WGS-84 standard) at a frequency of 0.1Hz, simultaneously collecting vibration data from the built-in triaxial accelerometer (range ±8g) and temperature sensor readings (-40℃~+85℃). The data is encrypted with AES-256 and pushed to the cloud in real time via the MQTT protocol. The APP receives and parses the data via a WebSocket long connection, dynamically rendering it onto the Gaode / Google Maps interface to achieve overlay visualization of the transportation trajectory (≤2-second delay) and status parameters (temperature, vibration, power). The APP has a built-in threshold judgment engine (configurable rule base). When it detects positioning deviation from the electronic fence (±50m), continuous vibration exceeding limits (>0.3g), or abnormal temperature (ΔT>20℃ / h), it immediately triggers multi-level alarms (pop-up / SMS / work order) and activates offline caching (SQLite stores 24 hours of data). During installation, the APP reads the RFID tag (ISO) of the cable sealing device via Bluetooth 5.2. The 18000-6C standard associates a unique ID with the installation location and construction personnel information. The data is then encrypted via HTTPS and transmitted back to the operation and maintenance platform, forming a full lifecycle traceability chain.

[0049] Meanwhile, by integrating IoT positioning technology (GPS / RFID / UWB) + cloud data platform + mobile visualization system, the entire chain of cable location tracking and status monitoring from production, warehousing, transportation, installation to post-maintenance can be realized, ensuring that the physical location and status parameters of each link can be traced in real time.

[0050] Furthermore, since the intelligent detection component 3 is detachable, the device can be recycled and reused, thus saving resources.
