[0020] The present invention will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0021] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in , , and , a cable with multi-channel and high heat dissipation self-checking module includes an internal conductor. A filling inner sheath 1, an armor 2, and an outer sheath 3 are respectively arranged outside the internal conductor. The internal conductor includes a core wire 4, a core wire shield 5, an insulating layer 6, an insulating shield layer 7, a water-blocking tape 8, and a PE sheath 9. An inner layer diversion pipe 10 with a spiral structure layout is arranged between the filling inner sheath 1 and the PE sheath 9. A spiral-shaped outer side diversion groove 11 is formed on the inner side surface of the outer sheath 3. Axially upwardly protruding lateral connection covers 12 are provided at both ends of the outer sheath 3. An end detection assembly cover 13 is axially fixed at the position of the lateral connection cover 12. A circulating diversion fan 14 communicating with the inner layer diversion pipe 10 and the outer side diversion groove 11 is arranged inside the end detection assembly cover 13.

[0023] Adjacent cables are fixed through the end detection and assembly cover 13. By rotating, the inner diversion pipe 10, the outer diversion groove 11, and the circulating diversion fan 14 are connected in series. When the circulating diversion fan 14 rotates, air is drawn from the inner diversion pipe 10 into the interior of the end detection and assembly cover 13, and then flows back from the end detection and assembly cover 13 into the interior of the outer diversion groove 11. The outer sheath 3 dissipates the internal temperature to the outside, and at the same time, the overall external impact resistance of the cable can be improved by inflating the interior.

[0024] To facilitate installation and connection, a first connecting conduit 121 communicating with the inner diversion pipe 10 and a second connecting conduit 122 communicating with the outer diversion groove 11 are fixed on the inner side surface of the lateral connecting cover 12. A first connecting cover pipe 131 cooperating with the first connecting conduit 121 and a second connecting cover pipe 132 cooperating with the second connecting conduit 122 are fixedly assembled on the inner side surface of the end detection and assembly cover 13.

[0025] The first connecting cover pipe 131 is sleeved on the first connecting conduit 121 and is connected and fixed to the first connecting conduit 121. The second connecting cover pipe 132 is sleeved on the second connecting conduit 122 and is connected and fixed to the second connecting conduit 122.

[0026] To facilitate assembly and fixation on both sides, closed sealing grooves cooperating with the lateral connecting cover 12 are symmetrically provided on both sides of the end detection and assembly cover 13.

[0027] To facilitate locking and fixation, telescopic locking buckles 15 are installed on the arc surface of the closed sealing groove, and an annular adjusting assembly 16 for controlling the telescopic locking buckles 15 is installed inside the end detection and assembly cover 13.

[0028] To facilitate installation, an annular diversion chamber 133 for installing the circulating diversion fan 14 is fixedly assembled inside the end detection and assembly cover 13.

[0029] To facilitate connection and diversion, both the first connecting cover pipe 131 and the second connecting cover pipe 132 are connected to the inside of the annular diversion chamber.

[0030] To facilitate temperature and humidity monitoring and control, a temperature sensing module 17 and a humidity sensing module 18 are respectively and fixedly installed inside the first connecting cover pipe 131 and the second connecting cover pipe 132.

[0031] The temperature sensing module 17 is fixed inside the first connecting cover pipe 131, and the humidity sensing module 18 is fixed inside the second connecting cover pipe 132.

[0032] To facilitate electric control of the external circulation, two electric control one-way valves 19 are provided on the side wall of the end detection and assembly cover 13.

[0033] To cooperate with the switching control between the internal and external cycles, the electronically controlled one-way valve 19 is composed of a magnetically controlled one-way valve in the prior art. One is responsible for one-way inward air extraction, and the other is responsible for one-way outward exhaust. When the internal circulation temperature in the cable accumulates heat severely, and the humidity sensor on the outer surface of the end detection and assembly cover 13 monitors that the dryness meets the requirements, at this time, the electronically controlled one-way valve 19 on the side wall of one end detection and assembly cover 13 opens for external air intake, and the electronically controlled one-way valve 19 on the side wall of the other end detection and assembly cover 13 opens for external exhaust. At this time, an air flow path for the external cycle can be formed.

[0034] Once the external cycle starts, it indicates that water has entered the cable. A warning signal is sent to the remote terminal through the communication components in the cable in the prior art. The signal transmission method and installation method are in the prior art. Then, the remote terminal monitors the humidity change inside the cable. If the humidity change remains unchanged, manual maintenance is required; if the humidity decreases, no manual maintenance is required.

[0035] To cooperate with the adjustment and locking, an inner telescopic groove matching the telescopic locking buckle 15 is provided on the arc surface of the closing sealing groove. The telescopic locking buckle 15 includes an arc-shaped adjustment cover 151 slidably installed in the inner telescopic groove, a locking tongue 152 fixed on the extrusion surface of the arc-shaped adjustment cover 151, and a control lead screw 153 threadedly assembled inside the arc-shaped adjustment cover 151.

[0036] To cooperate with the adjustment and rotation, the annular adjustment assembly 16 includes an external control seat 161 fixed on the outer side surface of the end detection and assembly cover 13, an adjustment worm 162 movably installed inside the external control seat 161, and an annular partial gear ring 163 movably installed inside the end detection and assembly cover 13. The lateral tooth surface of the annular partial gear ring meshes with the top straight tooth head of the control lead screw 153 for transmission, and the worm gear surface on the outer arc surface of the annular partial gear ring 163 meshes with the adjustment worm 162 for transmission.

[0037] By rotating the adjustment worm 162, the annular partial gear ring 163 is driven to rotate. Then, the annular partial gear ring 163 drives the straight tooth head at the top of the control lead screw 153, synchronously driving the control lead screw 153 to rotate. Then, the control lead screw 153 drives the arc-shaped adjustment cover 151 to slide and adjust inside the inner telescopic groove. The locking tongue 152 on the inner side of the arc-shaped adjustment cover 151 is used to squeeze and lock the outer side of the lateral connection cover 12, thereby fixedly assembling the lateral connection cover 12 and the end detection and assembly cover 13.

[0038] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
