Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a cable with multi-channels and a high heat dissipation self-checking module. Background Art

[0002] A cable is a wire product used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. It mainly consists of one or more insulated wire cores, as well as the covering layer, protective layer, and outer protective layer on its outer side. During use, cables are mostly in complex mechanical stress and corrosive environments. After long-term use, problems such as fatigue damage or corrosion are likely to occur, directly affecting the service life of the cable. Traditional cables can neither monitor the state changes of their inner and outer layers in real time, nor assist in improving the internal heat dissipation effect, and cannot automatically switch the inner and outer circulation modes according to the internal temperature changes, resulting in a very limited heat dissipation effect and relatively troublesome connection and disassembly. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that traditional cables can neither monitor the state changes of their inner and outer layers in real time, nor assist in improving the internal heat dissipation effect, and cannot automatically switch the inner and outer circulation modes according to the internal temperature changes, resulting in a very limited heat dissipation effect and relatively troublesome connection and disassembly.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a cable with multi-channels and a high heat dissipation self-checking module, including an internal conductor. A filling inner sheath, an armor, and an outer sheath are respectively arranged on the outer side of the internal conductor. The internal conductor includes a core wire, a core wire shield, an insulating layer, an insulating shield layer, a water blocking tape, and a PE sheath. An inner layer diversion tube with a spiral structure layout is arranged between the filling inner sheath and the PE sheath. A spiral-shaped outer side diversion groove is formed on the inner side surface of the outer sheath. Lateral connection covers protruding upward axially are provided at both ends of the outer sheath. An end detection assembly cover is axially fixed at the position of the lateral connection cover. A circulating diversion fan connected to the inner layer diversion tube and the outer side diversion groove is arranged inside the end detection assembly cover.

[0005] A first communication conduit connected to the inner layer diversion tube and a second communication conduit connected to the outer side diversion groove are fixed on the inner side surface of the lateral connection cover. A first communication cover tube matched with the first communication conduit and a second communication cover tube matched with the second communication conduit are fixedly assembled on the inner side surface of the end detection assembly cover.

[0006] Closed sealing grooves matched with the lateral connection cover are symmetrically formed on both sides of the end detection assembly cover.

[0007] Retractable locking buckles are installed on the arc-shaped surface of the closed sealing groove. An annular adjusting assembly for controlling the retractable locking buckles is installed inside the end detection assembly cover.

[0008] An annular diversion chamber for installing a circulating diversion fan is fixedly assembled inside the end detection assembly cover.

[0009] Both the first connecting cover pipe and the second connecting cover pipe are connected to the inside of the annular diversion chamber.

[0010] A temperature sensing module and a humidity sensing module are respectively and fixedly installed inside the first connecting cover pipe and the second connecting cover pipe.

[0011] Two electric control one-way valves are arranged on the side wall of the end detection assembly cover.

[0012] An inner expansion groove matched with the telescopic locking buckle is formed on the arc surface of the closing sealing groove. The telescopic locking buckle includes an arc-shaped adjusting cover slidably installed in the inner expansion groove, a locking tongue fixed on the extrusion surface of the arc-shaped adjusting cover, and a control lead screw threadedly assembled inside the arc-shaped adjusting cover.

[0013] The annular adjusting assembly includes an external control seat fixed on the outer side surface of the end detection assembly cover, an adjusting worm rotatably installed inside the external control seat, and an annular partial gear ring rotatably installed inside the end detection assembly cover. The lateral tooth surface of the annular partial gear ring is meshed and driven with the top straight tooth head of the control lead screw, and the worm gear surface on the outer arc surface of the annular partial gear ring is meshed and driven with the adjusting worm.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) In a cable with a multi-channel and high heat dissipation self-checking module of the present invention, an inner layer diversion pipe with a spiral structure layout is arranged between the filling inner sheath and the PE sheath, a spiral-shaped outer diversion groove is formed on the inner side surface of the outer sheath, and end detection assembly covers are axially fixed at both ends of the cable. A circulating diversion fan inside the end detection assembly cover forms a circulating flow path between the inner layer diversion pipe and the outer layer diversion groove, so that the inner and outer layers can be quickly heat-exchanged, greatly improving the heat exchange performance of the whole cable;

[0016] (2) By adopting the design of the inner layer diversion pipe and the outer layer diversion groove, the safety of the heat dissipation structure of the whole cable can be greatly ensured;

[0017] (3) The use of the inner layer diversion pipe with a spiral structure layout and the outer layer diversion groove does not affect the bending of the cable;

[0026] The present invention will now be further described in detail with reference to 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.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connection" 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 situations.

[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4A cable with a multi-channel and high heat dissipation self-check module is shown, including 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 tube 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 opened on the inner side surface of the outer sheath 3. Axially at both ends of the outer sheath 3, there are upwardly protruding lateral connection covers 12. An end detection assembly cover 13 is axially fixed at the position of the lateral connection cover 12. Inside the end detection assembly cover 13, there is a circulating diversion fan 14 connected to the inner layer diversion tube 10 and the outer side diversion groove 11.

[0029] Adjacent cables are fixed through the end detection assembly cover 13. By rotating, the inner layer diversion tube 10, the outer side diversion groove 11, and the circulating diversion fan 14 are connected in series. Through the rotation of the circulating diversion fan 14, air is drawn from the inner layer diversion tube 10 into the inside of the end detection assembly cover 13, and then flows back from the end detection assembly cover 13 into the inside of the outer side diversion groove 11. The outer sheath 3 dissipates the internal temperature to the outside. At the same time, the overall external impact resistance of the cable can be improved by inflating the inside.

[0030] In order to cooperate with the installation and connection, a first communication conduit 121 connected to the inner layer diversion tube 10 and a second communication conduit 122 connected to the outer side diversion groove 11 are fixed on the inner side surface of the lateral connection cover 12. A first communication cover tube 131 matched with the first communication conduit 121 and a second communication cover tube 132 matched with the second communication conduit 122 are fixedly assembled on the inner side surface of the end detection assembly cover 13.

[0031] The first communication cover tube 131 is sleeved on the first communication conduit 121 and connected and fixed to the first communication conduit 121. The second communication cover tube 132 is sleeved on the second communication conduit 122 and connected and fixed to the second communication conduit 122.

[0032] In order to cooperate with the assembly and fixation on both sides, closed sealing grooves matched with the lateral connection cover 12 are symmetrically opened on both sides of the end detection assembly cover 13.

[0033] In order to cooperate with the locking and fixation, telescopic locking buckles 15 are installed on the arc surface of the closed sealing groove. An annular adjustment assembly 16 for controlling the telescopic locking buckles 15 is installed inside the end detection assembly cover 13.

[0034] In order to cooperate with the installation, an annular diversion chamber 133 for installing the circulating diversion fan 14 is fixedly assembled inside the end detection assembly cover 13.

[0035] In order to cooperate with the connection and diversion, both the first communication cover tube 131 and the second communication cover tube 132 are connected to the inside of the annular diversion chamber.

[0036] To cooperate with temperature and humidity monitoring and control, a temperature sensing module 17 and a humidity sensing module 18 are respectively fixedly installed inside the first connecting hood tube 131 and the second connecting hood tube 132.

[0037] The temperature sensing module 17 is fixed inside the first connecting hood tube 131, and the humidity sensing module 18 is fixed inside the second connecting hood tube 132.

[0038] To cooperate with the electric control external circulation, two electric control one-way valves 19 are arranged on the side wall of the end detection and assembly hood 13.

[0039] To cooperate with the switching control between internal and external circulations, the electric control 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 air exhaust. When the internal circulation temperature heat collection inside the cable is serious, and the humidity sensor on the outer surface of the end detection and assembly hood 13 monitors that the dryness meets the requirements, at this time, the electric control one-way valve 19 on the side wall of one end of the end detection and assembly hood 13 opens for external air intake, and the electric control one-way valve 19 on the side wall of the other end of the end detection and assembly hood 13 opens for external air exhaust. At this time, an air flow channel for external circulation can be formed.

[0040] Once the external circulation 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.

[0041] To cooperate with adjustment and locking, an inner expansion slot matched with the telescopic locking buckle 15 is arranged 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 expansion slot, 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.

[0042] To cooperate with 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 hood 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 hood 13. The lateral tooth surface of the annular partial gear ring meshes and drives with the top straight tooth head of the control lead screw 153, and the worm gear tooth surface on the outer arc surface of the annular partial gear ring 163 meshes and drives with the adjustment worm 162.

[0043] By rotating the adjusting worm 162, the annular offset gear ring 163 is driven to rotate, and then the straight tooth head at the top of the control lead screw 153 is driven by the annular offset gear ring 163 to synchronously drive the control lead screw 153 to rotate. Then, the control lead screw 153 drives the arc-shaped adjusting cover 151 to slide and adjust inside the inner telescopic groove, and the locking tongue 152 on the inner side of the arc-shaped adjusting cover 151 is used to squeeze and lock the outside of the lateral connecting cover 12, so as to fixedly assemble the lateral connecting cover 12 and the end detection assembly cover 13.

[0044] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing 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.
